[0055] Referring to FIGS. 1a-1e, a male sexual stimulation device according to an embodiment of the present disclosure is shown. In this embodiment, the male sexual stimulation device 100k includes a first stimulation member 20k, a second stimulation member 30k, and a driving assembly.

[0056] As shown in FIG. 1c and FIG. 1e, the first stimulation member 20k defines a first chamber 22k therein, and the second stimulation member 30k defines a second chamber 32k therein. The first chamber 22k and the second chamber 32k are arranged in sequence along an axial direction of the male sexual stimulation device 100k, communicating with each other and cooperatively forming an accommodating chamber. The accommodating chamber is elongated and generally column-shaped, and configured with a shape and a size being suitable for accommodating a male genitalia therein.

[0057] During use, as shown in FIG. 1c, the male genitalia is inserted into the accommodating chamber of the device 100k. Under the action of the driving assembly, the first stimulation member 20k generates a first motion, such as clamping and kneading; and, the second stimulation member 30k generates a different second motion, such as linear movement, rotation, vibration, and etc. The first and second stimulation members 20k, 30k simultaneously stimulate the male genitalia in different manners, thus the user is more likely to reach orgasm with the help of the present device 100k.

[0058] The first and second stimulation members 20k, 30k are both made of soft materials, such as silicone, which have a soft touch and a certain elastic buffering effect, making the users feel more comfortable. In this embodiment, the second stimulation member 30k is hollow and cylindrical-shaped, and the second chamber 32k extends through two axial ends of the second stimulation member 30k. When the device 100k is in use, the male genitalia is inserted into the second chamber 32k through an end of the second stimulation member 30k away from the first stimulation member 20k. A front end of the male genitalia, i.e. the glans, passes through the second chamber 32k and extends into the first chamber 22k of the first stimulation member 20k. Preferably, an end of the first stimulation member 20k away from the second stimulation member 30k is closed, enclosing the glans of the male genitalia that extends into the first chamber 22k.

[0059] As shown in FIG. 1c, in this embodiment, the first and second stimulation members 20k, 30k are separated from each other in the axial direction, with a gap defined therebetween, so that the first and second stimulation members 20k, 30k do not interfere with each other during movement. In some embodiments, elastic structures such as elastic sheets, elastic strips, etc. may be provided between the first and second stimulation members 20k, 30k, as long as they do not affect their movement, especially not affect telescopic movement of the second stimulation member 30k. Preferably, the elastic structure is integrally formed with the first and second stimulation members 20k, 30k through injection molding.

[0060] As shown in FIG. 1i, in this embodiment, the first stimulation member 20k is generally mouth-like, and includes a first stimulation portion 20ak and a second stimulation portion 20bk which are opposite to each other, and the first chamber 22k is defined between the first stimulation portion 20ak and the second stimulation portion 20bk. Under the action of the driving assembly, the first stimulation portion 20ak and the second stimulation portion 20bk swing towards or away from each other, clamping and kneading the glans of the male genitalia accommodated in the first chamber 22k. In the illustrated embodiment, the first stimulation portion 20ak and the second stimulation portion 20bk may be connected with each other in a circumferential direction, so that the first stimulation member 20k in whole is annular and can more tightly enclose the glans of the male genitalia.

[0061] Preferably, the first stimulation member 20k is concave at a connection point of the first stimulation portion 20ak and the second stimulation portion 20bk, so that the swinging of the first stimulation portion 20ak and second stimulation portion 20bk will not affect each other. In some embodiments, the first stimulation portion 20ak and the second stimulation portion 20bk may be separated in the circumferential direction, which is not limited to specific embodiments.

[0062] As shown in FIGS. 1f-1i, the driving assembly includes a driving source and swinging arms. In this embodiment, the swinging arms includes a first swinging arm 56ak engaged with the first stimulation portion 20ak, and a second swinging arm 56bk engaged with the second stimulation portion 20bk.

[0063] The driving source preferably is a gear motor, and includes a driving motor 40k and first and second output wheels 42k, 44k driven by the motor 40k to rotate with a speed about of 1000k rpm. The first output wheel 42k is connected to the first and second swinging arms 56ak through a first transmission unit 50k, so as to drive the first stimulation portion 20ak and the second stimulation portion 20bk of the first stimulation member 20k to swing relative to each other. The second output wheel 44k is connected to the second stimulation member 30k through a second transmission unit 60k, so as to drive the second stimulation member 30k to do reciprocating movement in the axial direction.

[0064] As shown in FIG. 1f and FIG. 1i, the first transmission unit 50k includes a first transmission member 52k and a first sliding member 54k.

[0065] The first transmission member 52k is connected to the first output wheel 42k, including a first transmission shaft 53k that is eccentrically set relative to a rotary axis of the first output wheel 42k. When the first output wheel 42k rotates, the first transmission shaft 53k revolves around the rotary axis of the first output wheel 42k. Referring to FIG. 8k, the rotary axis of the first output wheel 42k extends along the Y direction, and the first transmission shaft 53k rotates in the XZ plane, generating displacements in both the X direction and the Z direction.

[0066] The first sliding member 54k is provided with a first sliding groove 541k, and the first transmission shaft 53k is slidably inserted into the first sliding groove 541k. The first sliding groove 541k is elongated, with a width in the X direction substantially equivalent to the diameter of the first transmission shaft 53k and a length in the Z direction much greater than the diameter of the first transmission shaft 53k. In this way, the movement of the first transmission shaft 53k in the X direction causes the first sliding member 54k to move together in the X direction; while the movement of the first transmission shaft 53k in the Z direction is converted into the sliding of the first transmission shaft 53k along the first sliding groove 541k relative to the first sliding member 54k.

[0067] By means of cooperation of the first transmission shaft 53k and the first sliding groove 541k, the rotation of the first transmission member 52k in the XZ plane is converted into a linear reciprocating movement of the first sliding member 54k in the X direction. Preferably, as shown in FIG. 1d and FIG. 1i, the first sliding member 54k protrudes outwardly to form a first guide block 543k, and a first guide member 70k with an elongated first guide groove 72k is provided and fixed inside the device 100k. After assembly, the first guide block 543k of the first sliding member 54k is slidably engaged into the first guide groove 72k of the first guide member 70k, guiding the movement of the first sliding member 54k in the X direction.

[0068] The first swinging arm 56ak and the second swinging arm 56bk are generally the same in construction and arranged opposite to each other. Each of the first and second swinging arms 56ak, 56bk includes a connecting section 561k and a swinging section 563k. The connecting sections 561k of the two swinging arms 56ak, 56bk are movably connected to the first sliding member 54k, and the swinging sections 563k of the two swinging arms 56ak, 56bk extend into the first stimulation portion 20ak and the second stimulation portion 20bk of the first stimulation member 20k, respectively.

[0069] Preferably, the first swinging arm 56ak and the second swinging arm 56bk are made of hard materials, such as plastic, metal and etc., which can better transmit the force to the first stimulation portion 20k and the second stimulation portion 20bk. Preferably, during the process of forming the first stimulation member 20k, the swinging section 563k of the first swinging arm 56ak is fixed integrally into the first stimulation portion 20ak, and the swinging section 563k of the second swinging arm 56bk is fixed integrally into the second stimulation portion 20bk.

[0070] In this embodiment, the connecting section 561k and swinging section 563k of each of the two swinging arms 56ak, 56bk are angled with each other, and a pivot 80k is provided at a connection of the connecting section 561k and swinging section 563k of each of the two swinging arms 56ak, 56bk. The two pivots 80k are arranged in parallel intervals, and extend along the Y direction that is perpendicular to the telescopic movement direction (i.e., the X direction) of the first sliding member 54k. By means of the pivots 80k, the two swinging arms 56ak, 56bk can be rotatably set into the device 100k. In some embodiments, the pivots 80k are fixed in the device 100k, and each swinging arm 56ak, 56bk is rotatably mounted around a corresponding pivot 80k. In some embodiments, each swinging arm 56ak, 56bk may be fixedly connected to the corresponding pivot 80k, and the pivots 80k are rotatably set in the device 100k.

[0071] When the first sliding member 54k moves in the X direction, the connecting sections 561k of the two swinging arms 56ak, 56bk move along with the first sliding member 54k, causing the two swinging arms 56ak, 56bk to rotate around their respective axis rods 80k, thereby causing the swinging sections 563k of the two swinging arms 56ak, 56bk to swing towards or away from each other, finally driving the first stimulation portion 20ak and the second stimulation portion 20bk to swing towards/away from a central portion of the first chamber 22k synchronously. When the first stimulation portion 20ak and the second stimulation portion 20bk swing towards each other, the first stimulation member 20k is closed to clamp the male genitalia; and, when the first stimulation portion 20ak and the second stimulation portion 20bk swing away from each other, the first stimulation member 20k is opened to release the male genitalia. Compared to existing devices, the first stimulation member 20k, which clamps and kneads the male genitalia, especially the glans of the male genitalia, provides more effective stimulation, so that the user is more likely to reach orgasm.

[0072] As shown in FIG. 1i, the first sliding groove 541k is provided at one end of the first sliding member 54k, and the other end of the first sliding member 54k protrudes outwardly to form a connecting portion 545k. The connecting section 561k of each swinging arm 56ak, 56bk defines a connecting hole 565k therein, and the connecting portion 545k is movably inserted into the connecting holes 565k of the swinging arms 56ak, 56bk. When the first sliding member 54k moves in the X direction, the connecting portion 545k can move and rotate in the connecting holes 565k of the swinging arms 56ak, 56bk, thereby allowing the swinging arms 56ak, 56bk to rotate about the corresponding pivot 80k. In this embodiment, the first sliding member 54k is provided with two connecting portions 545k, each of which is inserted into the connecting hole 565k of one of the two swinging arms 56ak, 56bk.

[0073] In some embodiments, one of the first swinging arm 56ak and the second swinging arm 56bk may be fixed, for example, the first swinging arm 56ak may be fixed inside the device 100k, and the second swinging arm 56bk may be rotatably mounted inside the device 100k through the pivot 80k. In this situation, the first sliding member 54k is connected to the connecting section 561k of the second swinging arm 56bk, allowing the second swinging arm 56bk to rotate about the pivot 80k, thereby enabling the swinging section 563k of the second swinging arm 56bk to swing relative to the first swinging arm 56ak. In this way, the first stimulation portion 20ak of the first stimulation member 20k remains stationary, and the second stimulation portion 20bk swings back and forth relative to the first stimulation portion 20ak under the driving of the second swinging arm 56bk, which may also produce a clamping and kneading stimulation effect to the male genitalia that extends into the first chamber 22k.

[0074] In some embodiments, a vibration motor 58k may be provided in the first stimulation portion 20ak and/or second stimulation portion 20bk of the first stimulation member 20k (referring to FIG. 1c), so that the first stimulation member 20k can further stimulate the male genitalia through vibration, further improving the stimulation effect.

[0075] As shown in FIG. 1f and FIG. 1i, the second transmission unit 60k includes a second transmission member 62k and a second sliding member 64k.

[0076] The second transmission member 62k is connected to the second output wheel 44k, and includes a second transmission shaft 63k that is set eccentrically relative to a rotary axis of the second output wheel 44k. When the second output wheel 44k rotates, the second transmission shaft 63k revolves around the rotary axis of the second output wheel 44k. Referring to FIG. 7k, the rotary axis of the second output wheel 44k extends along the Z direction, and the second transmission shaft 63k rotates in the XY plane, generating displacements in both the X direction and the Y direction.

[0077] The second sliding member 64k is provided with a second sliding groove 641k, and the second transmission shaft 63k is movably inserted into the second sliding groove 641k. The second sliding groove 641k is elongated, with a width in the X direction substantially equivalent to the diameter of the second transmission shaft 63k and a length in the Y direction much greater than the diameter of the second transmission shaft 63k. In this way, the movement of the second transmission shaft 63k in the X direction causes the second sliding member 64k to move together in the X direction; and, the movement of the second transmission shaft 63k in the Y direction is converted into the sliding of the second transmission shaft 63k along the second sliding groove 641k relative to the second sliding member 64k.

[0078] By means of cooperation of the second transmission shaft 63k and the second sliding groove 641k, the rotation of the second transmission member 62k in the XY plane is converted into linear reciprocating motion of the second sliding member 64k in the X direction. Preferably, as shown in FIG. 1e and FIG. 1i, the second sliding member 64k protrudes outwardly to form a second guide block 643k, and the device 100k is fixedly provided with a second guide member 74k, and a second guide member 74k with an elongated second guide groove 76k is fixed inside the device 100k. The second guide block 643k of the second sliding member 64k is engaged into the second guide groove 76k of the second guiding member 74k, guiding the movement of the second sliding member 64k in the X direction.

[0079] In the illustrated embodiment, the second transmission unit 60k is set at an end of the first stimulation member 20k away from the second stimulation member 30k. There is a large distance between the second sliding member 64k and the second stimulation member 30k, and a connecting rod 66k is provided therebetween to achieve long-distance power transmission, so that the second sliding member 64k can drive the second stimulation member 30k to move back and forth in the X direction, stimulating a portion of the male genitalia, such as a rear end of the male genitalia, in the second chamber 32k. It should be understood that, according to the position of the second sliding member 64k and the second stimulation member 30k inside the device 100k, the connecting rod 66k may be single or multiple. In some embodiments, when the positions of the second sliding member 64k and the second stimulating member 30k are close to each other, the connecting rod 66k may be omitted.

[0080] As shown in FIG. 1c and FIG. 1i, a plurality of protrusions 34k extends inwardly from an inner circumferential surface of the second stimulation member 30k towards the second chamber 32k. The protrusions 34k may be convex points, convex pillars, convex strips, convex ribs, etc., which compresses the male genitalia in the second chamber 32k, further enhancing the stimulation effect of the second stimulation member 30k.

[0081] As shown in FIG. 1c and FIG. 1i, an outer circumferential surface of the second stimulation member 30k is concaved to form an annular groove, in which a fixing ring 36k is accommodated. The fixing ring 36k may be made of hard material and used for connecting the second stimulation member 30k to the second transmission unit 60k. Preferably, the fixing ring 36k is integrally fixed onto the second stimulation member 30k during the injection molding process of the second stimulation member 30k.

[0082] As shown in FIG. 1f and FIG. 1i, an outer wall of the fixing ring 36k protrudes to form a guide portion 38k, in which a guide rod 82k is movably inserted. The guide rod 82k is fixed in the device 100k and extends along the X direction, so as to guide the movement of the second stimulation member 30k in the X direction. The guide portion 38k and the guide rod 82k are preferably multiple, so that the force on the second stimulation member 30k is more balanced, and thus the movement of the second stimulation member 30ki s more stable.

[0083] Specifically, the first guide member 70k, the second guide member 74k, the pivots 80k, the guide rods 82k, and the like may be fixed in a shell 90k of the device 100k. As shown in FIG. 1e, the shell 90k includes an inner shell and an outer shell that encloses the inner shell, wherein the inner shell includes a first inner shell 92k, a second inner shell 93k, and a third inner shell 94k, and the outer shell includes a first shell 96k and a second shell 97k.

[0084] The first inner shell 92k is generally cylindrical-shaped, with a first space therein for mounting the first and second stimulation members 20k, 30k. The second inner shell 93k and the second inner shell 93k are connected to each other by, for example, snap-fitting, and a second space is formed therebetween for mounting the transmission unit. Preferably, as shown in FIG. 1c, a structure formed by the second inner shell 93k and the second inner shell 93k has an open end at a side thereof facing the first stimulation member 20k, and a close end of the first stimulation member 20k covers and seals the open end.

[0085] The first shell 96k and the second shell 97k, which may be connected through snap-fitting, cooperatively form the outer shell of the device 100k. Preferably, the outer shell and the first inner shell 92k are spaced from each other in the radial direction, thereby forming a space therebetween for extending of the connecting rod 66k therethrough to connecting the second stimulation member 30k to the second transmission unit 60k. In the illustrated embodiment, an end of the connecting rod 66k is provided with a pin 68k, and the first inner shell 92k forms a slot which is elongated in the X direction. During assembly, the pin 68k extends through the slot into the first inner shell 92k to connect the fixing ring 36k.

[0086] As shown in FIG. 1c and FIG. 1e, the shell 90k is further equipped with a battery 84k, a circuit board, and etc. The battery 84k is electrically connected to electronic components inside the device 100k, such as the driving motor 40k, the vibration motor 58k, etc., through the circuit board. Control buttons 99k are provided on the shell 90k, through which the operation of the device 100k, such as the rotary speed and direction of the driving motor 40k, the vibration frequency of the vibration motor 58k, and etc., can be controlled, so that the first and second stimulation members 20k, 30k can provide different degrees of stimulation according to user needs.

[0087] In this embodiment, the first output wheel 42k and the second output wheel 44k are both gears and mesh with each other. The rotary axis of the first output wheel 42k is perpendicular to the rotary axis of the second output wheel 44k, so that the first transmission component 50k and the second transmission unit 60k can be arranged at different sides of the device 100k, fully utilizing the internal space of the device 100k and making the product size controllable. In addition, meshing of the first output wheel 42k and the second output wheel 44k allows the first and second stimulation members 20k, 30k both to be driven by the same motor 40k, further simplifying the structure and saving costs.

[0088] In the illustrated embodiment, a transmission component 46k, such as a worm gear, is provided between the driving motor 40k and the first output wheel 42k, the second output wheel 44k, which can not only transmit the torque from the driving motor 40k to the first output wheel 42k and the second output wheel 44k, but also change the direction of torque transmission as needed. In some embodiments, other transmission units, such as bevel gears, planetary gears, pulleys, etc., or a combination of multiple transmission units, may be provided between the driving motor 42k and the first and second output wheels 42k, 44k.

[0089] In addition, in some embodiments, the driving assembly may include multiple driving motors, wherein the first output wheel 42k and the second output wheel 44k are separated from each other and connected to different driving motors, so that the movement of the first and second stimulation members 20k, 30k can be controlled separately.

[0090] Referring to FIGS. 1j-1m, a male sexual stimulation device according to another embodiment of the present disclosure is shown. In this embodiment, the male sexual stimulation device 100k includes a first stimulation member 20k, a second stimulation member 30k, and a driving assembly. A first chamber 22k is defined in the first stimulation member 20k, and a second chamber 32k is defined in the second stimulation member 30k. The first chamber 22k and the second chamber 32k are arranged in sequence and communicated to each other, cooperatively forming an accommodating chamber to accommodate a male genitalia.

[0091] Differently, the driving assembly of this embodiment includes a first motor 47k and a second motor 48k, wherein the first motor 47k is used to drive the first stimulation member 20k, and the second motor 48k is used to drive the second stimulation member 30k.

[0092] In this embodiment, the first motor 47k is a rotary motor that drives an output wheel 49k to rotate at an appropriate speed. The output wheel 49k is connected to the first and second swinging arms 56ak, 56bk through a transmission unit 50k. As shown in FIG. 1m and FIG. 1n, the transmission unit 50k includes a first transmission member 52k and a first sliding member 54k. The first transmission member 52k includes a first transmission shaft 53k eccentrically arranged relative to a rotary axis of the output wheel 49k, and a first sliding groove 541k is defined in the first sliding member 54k. The first transmission shaft 53k is movably inserted into the first sliding groove 541k.

[0093] The first swinging arm 56ak and the second swinging arm 56bk each are rotatably mounted in the device 100k through a pivot 80k, with one end thereof movably connected to the first sliding member 54k and the other end thereof extending into the first stimulation portion 20ak or the second stimulation portion 20bk of the first stimulation member 20k.

[0094] Under the action of the first motor 47k, the first transmission shaft 53k rotates in the XZ plane, and through its cooperation with the first sliding groove 541k, drives the first sliding member 54k to move back and forth in the X direction, which in turn drives the first swinging arm 56ak and the second swinging arm 56bk connected to it to swing relative to each other, finally causing the first stimulation portion 20ak and the second stimulation portion 20bk to clamp and knead the glans of the male genitalia accommodated in the first chamber 22k.

[0095] In this embodiment, the second motor 48k is a vibration motor embedded in the second stimulation member 30k, causing the second stimulation member 30k to vibrate at high frequency, thereby stimulating the male genitalia accommodated in the second chamber 32k.

[0096] In this embodiment, the first and second stimulation members 20k, 30k, under the action of the driving assembly, stimulate the male genitalia in different manners, wherein the first stimulation member 20k has a clamping and kneading effect on the male genitalia, and the second stimulation member 30k has a vibrating stimulating effect on the male genitalia. The two different effects enable the male genitalia to be fully stimulated, resulting in better user experience.

[0097] It should be understood that the second stimulation member 30k may be driven to move back and forth in the axial direction while vibrates under the driving of the second motor 48k, thereby further enhancing its stimulation effect. For example, a transmission unit may be provided to connect the second stimulation member 30k to the first motor 47k; or, an additional motor can be provided to drive the second stimulation member 30k to move back and forth.

[0098] It should be understood that the second stimulation member 30k may be driven to rotate while vibrates under the driving of the second motor 48k, thereby further enhancing its stimulation effect. The rotation of the second stimulation member 30k may be driven by the first motor 47k or by an additional motor. In addition, the linear movement, rotation of the second stimulation member may be performed independently, that is, without starting the vibration motor 48k or without setting the vibration motor 48k.

[0099] In this embodiment, as shown in FIG. 1l and FIG. 1m, the device 100k further includes an air pump 86k, which is connected to the first chamber 22k of the first stimulation member 20k through a pipeline, so as to suck air from the first chamber 22k to generate a negative pressure effect, further stimulating the male genitalia, especially the glans, in the first chamber 22k. As shown in FIG. 1l, the bottom of the first stimulation member 20k is provided with a hole 24k, which is connected to the pipeline of the air pump 86k, so that the air in the first chamber 22k can be discharged. To simplify the drawings, the pipeline between the air pump 86k and the hole 24k is not shown.

[0100] During use, the male genitalia may be stimulated only by the swinging of the first and/or second stimulation portions of the first stimulating member, and may be further stimulated by the linear movement, rotation, vibration, etc. of the second stimulating member, and/or may be further stimulated by the suction of the air pump, getting better stimulation effect and better user experience.

[0101] In conclusion, a pinching and holding function that stimulates the male penis is achieved by the above embodiment of the present disclosure. Furthermore, the present disclosure also provides the following embodiments that stimulates male penis by pinching and holding function.

[0102] According to another embodiment of the present disclosure, referring to FIGS. 2 to 5, a male sexual stimulation device 100 having an accommodating space 10 extending along a longitudinal direction of the male sexual stimulation device 100 for insertion of a male penis. The male sexual stimulation device 100 includes a first massage component 20 and a second massage component 30. The first and second massage components 20, 30 are arranged one after another in the longitudinal direction. The first massage component 20 defines a first cavity 11 constituting a first part of the accommodating space 10. The second massage component 30 defines a second cavity constituting a second part of the accommodating space 10. The first massage component 20 is drivable to slide in the longitudinal direction. The second massage component 30 is drivable to slide in the longitudinal direction too. Upon driven, the first massage component 20 and second massage component 30 slide towards or away from each other in the longitudinal direction.

[0103] The male sexual stimulation device 100 of the present disclosure is used for electrically massaging the genitalia, such as the penis, for providing an intense sexual stimulation to the penis. During use, the penis is inserted into the accommodating space 10 constituted by the first and second massage components 20, 30. With the reciprocating movements of the first massage component 20 and the second massage component 30 towards and away from each other, the first and second massage components 20, 30 cooperatively provide holding and pinching stimulation for penis, which improves the users' sexual experience.

[0104] In the above embodiment, the male sexual stimulation device 100 includes an actuator 60 and a transmission component 40 in torque-transmission connection with the actuator 60. The actuator 60 is arranged on a bottom side of the transmission component 40, and the first and second massage components 20, 30 are arranged on a top side of the transmission component 40. The first massage component 20 is in torque-transmission connection with the transmission component 40 and is drivable to slide by the actuator 60 through the transmission component 40. The second massage component 30 is in torque-transmission connection with the transmission component 40 and is drivable to slide by the actuator 60 through the transmission component 40.

[0105] That is, both the first and second massage components 20, 30 are in torque-transmission connection with the transmission component 40, so that the actuator 60 can simultaneously drive the first and second massage components 20, 30 to move towards or away from each other in the longitudinal direction via the transmission component 40. In FIG. 4, the longitudinal direction is indicated with the X-direction, and the Z-direction indicates a vertical direction extending in the top and bottom that is perpendicular to the longitudinal direction.

[0106] Specifically, the transmission component 40 includes a first actuating element 41 connected to the first massage component 20 and a second actuating element 42 connected to the second massage component 30. The first and second actuating elements 41, 42, driven by the actuator 60 drive the first and second massage components 20, 30 to slide towards or away from each other along the longitudinal direction.

[0107] Specifically, in one embodiment, referring to FIGS. 2 to 5, the first massage component 20 includes a first guide slider 21 having a first engagement groove 211, and the second massage component 30 includes a second guide slider 31 having a second engagement groove 311. The transmission component 40 includes at least one guide rail 43, preferably two guide rails 43. The two guide rails 43 are fixed relative to the housing 83, arranged in parallel and extend in the longitudinal direction. The first and second guide sliders 21, 31 are respectively slidably mounted on the two guide rails 43.

[0108] The first engagement groove 211 and the second engagement groove 311 are elongated. Extension directions of the first engagement groove 211 and second engagement groove 311 intersect respectively reciprocal sliding directions of the first massage component 20 and the second massage component 30. Preferably, the first engagement groove 211 extends along a lateral direction that is perpendicular to the reciprocal sliding direction of the first massage component 20, and the second engagement groove 311 extends along a lateral direction that is perpendicular to the reciprocal sliding direction of the second massage component 30. The lateral direction is indicated with the Y-direction shown in FIG. 4. The first actuating element 41 and the second actuating element 42 are slidably engaged in the first engagement groove 211 and the second engagement groove 311, respectively.

[0109] The first and second guide sliders 21, 31 are respectively slidably mounted to the two guide rails 43, providing guidance and limiting effect on the first and second massage components 20, 30. When the first and second actuating elements 41, 42 rotate, which cause movements of the first and second massage components 20, 30 through the engagements with the first and second engagement grooves 211, 311 respectively, due to the restriction of the fixed guide rails 43, the first and second massage components 20, 30 can only perform linear movements along the guide rails 43, which ensures that the first and second massage components 20, 30 can move stably and have a structural reliability during pinching massage for the penis. In particular, the design of the two parallel spaced apart guide rails 43 can form a dual-side restriction and guidance for the first and second massage components 20, 30, which can further improve the stability of the reciprocating movements of the first and second massage components 20, 30.

[0110] In the above embodiment, particularly refer to FIG. 3, the first massage component 20 includes a first flexible body 22 defining the first cavity 11 and a first support 23, and the second massage component 30 includes a second flexible body 32 defining the second cavity 12 and a second support 33.

[0111] The first support 23 is used to fix the first flexible body 22 to the first guide slider 21. The second support 33 is used to fix the second flexible body 32 to the second guide slider 31.

[0112] The first and second supports 23, 33 are typically made of materials with a certain hardness and anti-deformation ability, such as rigid plastics, metals, etc., so that the first and second supports 23, 33 can serve as the skeletons of the first and second flexible bodies 22, 32 to provide enough structural strength for supporting and positioning. For example, the first and second flexible bodies 22, 32 are annular, and correspondingly the first and second supports 23, 33 are also annular structures.

[0113] The first and second guide sliders 21, 31 are slidably mounted to the at least one guide rail 43, preferably two guide rails 43, so as to drive the first and second massage components 20, 30 to reciprocate along the at least one guide rail 43 with a certain travel distance, driven by the transmission component 40, thereby achieving the reciprocating movements of the first and second massage components 20, 30 towards and away from each other.

[0114] The first and second flexible bodies 22, 32 may be made of a soft material, including but not limited to stretchable soft silicone, which is non-toxic, antibacterial and chemically stable. Therefore, such skin-friendly soft material can improve the users' experience.

[0115] In the above embodiment, at least one of the first flexible body 22 and the second flexible body 32 may be a circumferentially closed annular structure. The first and second supports 23, 33 are attached to the exteriors of the first and second flexible bodies 22, 32, respectively. In other embodiments, at least one of the first flexible body 22 and the second flexible body 32 may be an annular structure with a notch, i.e., disconnected in the circumferential direction.

[0116] In the above embodiment, as shown in FIG. 3, a gap between the first massage component 20 and the second massage component 30 in the longitudinal direction defines a third cavity 13, that constitutes a third part of the accommodating space 10. That is, the penis may insert into the third cavity 13 along the longitudinal direction of the first and second flexible bodies 22, 32, and an end of the first flexible body 22 towards the second flexible body 32 and an end of the second flexible body 32 towards the first flexible body 22 squeeze the penis to achieve the massage effect.

[0117] Alternatively, the first cavity 11 defined by the first massage component 20, the second cavity 12 defined by the second massage component 30, and the third cavity 13 defined by the gap between the first massage component 20 and the second massage component 30 cooperatively form the accommodating space 10 for massaging the penis. During use, the penis is sequentially inserted into the first cavity 11, the third cavity 13, and the second cavity 12 along the longitudinal direction. The first and second massage components 20, 30 form a sliding kneading massage on the penis in the course of the reciprocating motions of the first and second massage components 20, 30 towards and away from each other.

[0118] Alternatively, the male sexual stimulation device 100 may include a connecting body provided between the first and second flexible bodies 22, 32 along the longitudinal direction. The first flexible body 22, the second flexible body 32 and the connecting body are integrally molded as a one-piece structure. The gap between the first and second flexible bodies 22, 32 and the connecting body forms the third cavity 13. The first cavity 11, the second cavity 12, and the third cavity 13 cooperatively form the accommodating space 10. Since the first flexible body 22, the second flexible body 32 and the connecting body are integrally molded as a one-piece structure, but the first guide slider 21 and the second guide slider 22 are two parts individual to each other, when the first and second guide sliders 21, 22 move towards or away from each other, the first and second flexible bodies 22, 32 will be deformed under the constraints of the connecting body, so that it is possible to form a pinch massage for the penis inserted into the accommodating space 10.

[0119] In the above embodiment, the male sexual stimulation device 100 further includes a housing 83. The actuator 60, the transmission component 40, and the first and second massage components 20, 30 are assembled to the housing 83. The housing 83 together with the actuator 60, the transmission component 40, and the first and second massage components 20, 30 form a modular structure, and the male sexual stimulation device 100 therefore has a compact structure and a lightweight volume, which is convenient to use and saves effort, enhancing the sense of using experience.

[0120] The male sexual stimulation device 100 further includes a circuit board 81 and a battery 82. The actuator 60 is a motor. The battery 82 is electrically connected to the circuit board 81. The circuit board 81 is electrically connected to the motor. The motor is in torque-transmission connection with the transmission component 40. The circuit board 81 is used to receive input commands or instructions from the users, such as switching on, switching off, adjusting the speed, mode, etc., the circuit board 81 then outputs working commands to the motor, so that the motor in turn can output corresponding torque to the transmission component 40 at a preset speed, and thereby controlling the first and second massage components 20, 30 to perform a reciprocating massage on the penis at the desired speed and squeezing force.

[0121] The battery 82 is used to power the entire device. Preferably, the battery 82 is a rechargeable battery 82 to enhance the durability and convenience in use of the male sexual stimulation device 100.

[0122] In one embodiment, the transmission component 40 may include specifically a drive gear 44, a first driven gear 45, and a second driven gear 46, a first eccentric rod 451, and a second eccentric rod 461. The drive gear 44 is in torque-transmission connection with the actuator 60. The first and second driven gears 45, 46 are both engaged with the drive gear 44 and arranged on radially opposite sides of the drive gear 44. The first eccentric rod 451 is fixed on the first driven gear 45 and slidably arranged within the first engagement groove 211 of the first guide slider 21. The second eccentric rod 461 is fixed on the second driven gear 46 and slidably arranged within the second engagement groove 311 of the second guide slider 31. That is, the first eccentric rod 451 fixed on the first driven gear 45 serves as the first actuating element 41, the second eccentric rod 461 fixed on the second driven gear 46 serves as the second actuating element 42.

[0123] During use, the actuator 60, i.e., the motor, drives the drive gear 44 to rotate, and the drive gear 44 in turn drives the first driven gear 45 and the second driven gear 46 to rotate in opposite directions simultaneously. The rotation of first driven gear 45 causes the first eccentric rod 451 to slide in the first engagement groove 211, and the first eccentric rod 451 in turn drives the first guide slider 21 to move by applying a push or pull force to the side wall of the first engagement groove 211, which in turn causes the first massage component 20 to move longitudinally along a first direction.

[0124] Similarly, the rotation of the second driven gear 46 causes the second eccentric rod 461 to slide in the second engagement groove 311, and the second eccentric rod 461 in turn drives the second guide slider 31 to move by applying a push or pull force to the side wall of the second engagement groove 311, which in turn causes the second massage component 30 to move longitudinally along a second direction opposite to the first direction. The first massage component 20 and the second massage component 30 move longitudinally in opposite directions, thereby enabling the two massage components 20, 30 to move linearly towards or away from each other, and achieving a massage effect on the penis.

[0125] FIGS. 6 and 7 show an alternative transmission component 40. In this embodiment, the actuator 60 is arranged on one longitudinal end of the first and second massage components 20, 30, and the transmission component 40 is arranged on a bottom side of the first and second massage components 20, 30. The actuator 60 is a motor. The battery 82 is electrically connected to the circuit board 81. The circuit board 81 is electrically connected to the motor.

[0126] The transmission component 40 includes a rotating wheel 50 having a third eccentric rod 501 and a push-pull rod 51 having an elongated hole 511. A drive shaft of the motor is in torque-transmission connection with the rotating wheel 50. The third eccentric rod 501 is slidably engaged into the elongated hole 511.

[0127] The transmission component 40 further includes a first moving block 47 having a first rack 471 extending along the longitudinal direction, a second moving block 48 having a second rack 481 extending along the longitudinal direction, and a transmission gear 49 meshed with both the first rack 471 and the second rack 481. The first and second racks 471, 481 are both engaged with the transmission gear 49 and disposed on opposite sides of the transmission gear 49. Two guide rails 43 are arranged in parallel and both extend in the longitudinal direction. The first and second massage portions 20, 30 are slidably mounted to the guide rails 43.

[0128] The first moving block 47 is connected to one longitudinal end of the push-pull rod 51, a portion of the first moving block 47 as the first actuating element 41 is engaged into the first engagement groove 211 of the first guide slider 21. A portion of the second moving block 48 as the second actuating element 42 is engaged into the second engagement groove 311. Two sides of each of the first guide slider 21 and the second guide slider 31 are slidably mounted to two guide rails 43 respectively.

[0129] In summary, the difference between the embodiment depicted in FIGS. 6-7 and the embodiment shown in FIGS. 2-5 are as follows. The embodiment depicted in FIGS. 6-7 adopts the push-pull movement of the push-pull rod 51, coupled with the meshing transmission among the first rack 471, the transmission gear 49 and the second rack 481. When the motor is actuated, the rotating wheel 50 together with the third eccentric rod 501 rotates, which causes the push-pull rod 51 to move linearly in a first direction, and drives the transmission gear 49 to rotate through the first rack 471, and the rotation of the transmission gear 49 drives the second rack 481 to move linearly in a second direction opposite to the first direction. The first rack 471 and the second rack 481 move linearly in opposite directions mean the first moving block 47 and the second moving block 48 move linearly in opposite directions, and the first moving block 47 and the second moving block 48 in turn drive the first guide slider 21 of the first massage component 20 and the second guide slider 31 of the second massage component 30 to move towards or away from each other, thereby achieving the massage effect on the penis inserted into the accommodating space 10.

[0130] In this embodiment, the portion of the first moving block 47 is engaged into the first engagement groove 211 of the first guide slider 21 to achieve the connection of the first moving block 47 and the first guide slider 21. The portion of the second moving block 48 is engaged into the second engagement groove 311 of the second guide slider 31 to achieve the connection of the second moving block 48 and the second guide slider 31. However, it should be noted that, the connection between the first moving block 47 and the first guide slider 21, and the connection between the second moving block 48 and the second guide slider 31 can be achieved by other means, for example, snapping-fitting, interference fit, or form-fitting connection. That is, in this embodiment, there is no need for the first moving block 47 to slide relative to the first guide slider 21, and there is no need for the second moving block 48 to slide relative to the second guide slider 31, the first and second moving blocks 47, 48 can thus be detachably or fixedly connected to the corresponding guide sliders 21, 31 by any known connection means. Alternatively, the first moving block 47 and the first guide slider 21 may be integrally formed as one single piece, and the second moving block 48 and the second guide slider 31 may be integrally formed as one single piece.

[0131] FIGS. 8 and 9, show a yet alternative transmission component 40. In this embodiment, the transmission component 40 is arranged on a bottom side of the first and second massage components 20, 30, and the actuator 60 is arranged on one longitudinal end of the transmission component 40. The actuator 60 is a motor. The battery 82 is electrically connected to the circuit board 81. The circuit board 81 is electrically connected to the motor.

[0132] The transmission component 40 includes a first transmission rod 52 extending along the longitudinal direction and a first gear set 53. A drive shaft of the motor is in torque-transmission connection with the first gear set 53. The first transmission rod 52 is provided with a first gear portion 521 and a first threaded portion 522 at two longitudinal ends, respectively. The first gear portion 521 is engaged with the first gear set 53.

[0133] The transmission component 40 further includes a first moving block 47, a second moving block 48, a transmission gear 49, and two guide rails 43. The guide rails 43 extend along the longitudinal direction and are arranged in parallel. The first moving block 47 includes a first threaded sleeve 472 and a first rack 471 connected to each other. The first rack 471 extends along the longitudinal direction. The first threaded sleeve 472 is threadedly engaged with an exterior of the first threaded portion 522. The first moving block 47 can move linearly but cannot rotate. Thus, due to the engagement between the first threaded portion 522 and the first threaded sleeve 472, the first moving block 47 moves linearly as the first transmission rod 52 rotates.

[0134] A portion of the first moving block 47 as the first actuating element 41 is engaged into the first engagement groove 211 of the first guide slider 21. The second moving block 48 is provided with a second rack 481 extending along the longitudinal direction. The first and second racks 471, 481 are both engaged with the transmission gear 49 and disposed on opposite sides of the transmission gear 49 along the lateral direction. A portion of the second moving block 48 as the second actuating element 42 is engaged into the second engagement groove 311. Two ends of each of the first guide slider 21 and the second guide slider 31 are slidably mounted on the two guide rails 43 respectively.

[0135] In summary, the differences between the embodiment shown in FIGS. 8-9 and the aforementioned embodiment of FIGS. 2-5 and embodiment of FIGS. 6-7 are as follows. The torque output from the motor is firstly transmitted to the first gear set 53, which reduces the speed and increases the torque by the first gear set 53 and then transmitted to the first transmission rod 52, which can drive the first transmission rod 52 to rotate though the first gear portion 521. During the rotation of the first transmission rod 52, due to the threaded engagement between the first threaded portion 522 and the first threaded sleeve 472, the first transmission rod 52 drives the first threaded sleeve 472, i.e., the first moving block 47 to push or pull the first guide slider 21 to move along the two guide rails 43, depending on the rotation direction of the motor. At the same time, due to the engagements among the first rack 471, the transmission gear 49 and the second rack 481, the linear movement of the first rack 471 corresponds to the linear movement of the second rack 481 in a direction opposite to that of the first rack 471, as a result, the first moving block 47 and the second moving block 48 move simultaneously in opposite directions, which in turn cause the first guide slider 21 of the first massage component 20 and the second guide slider 31 of the second massage component 30 to move towards or away from each other, thereby achieving the massage effect on the penis inserted into the accommodating space 10.

[0136] Similar to the embodiment shown in FIGS. 6-7, the first moving block 47 and the first guide slider 21 may be connected by other means or integrally formed as one single piece. The second moving block 48 and the second guide slider 21 may be connected by other means or integrally formed as one single piece. Details please refer to the above descriptions and will not be repeated again.

[0137] FIG. 10 shows a yet alternative transmission component 40. In this embodiment, the transmission component 40 is arranged on a bottom side of the first and second massage components 20, 30, and the actuator 60 is arranged on one longitudinal end of the transmission component 40. The actuator 60 is a motor. The battery 82 is electrically connected to the circuit board 81. The circuit board 81 is electrically connected to the motor.

[0138] The transmission component 40 includes a first transmission rod 52 extending along the longitudinal direction and a first gear set 53. A drive shaft of the motor is in torque-transmission connection with the first gear set 53. The first transmission rod 52 is provided with a first gear portion 521, a first threaded portion 522 and a second threaded portion 542. The first gear portion 521, the first threaded portion 522 and the second threaded portion 542 are spaced apart along an axial direction of the first transmission rod 52. The first gear portion 521 is engaged with the first gear set 53.

[0139] The transmission component 40 further includes a first moving block 47, a second moving block 48, and two guide rails 43 extending along the longitudinal direction and arranged in parallel along the lateral direction. The first moving block 47 includes a first threaded sleeve 472 threadedly engaged with an exterior of the first threaded portion 522. The first moving block 47 also includes a portion serving as the first actuating element 41 that is engaged into the first engagement groove 211 of the first guide slider 21. The second moving block 48 includes a second threaded sleeve 482 threadedly engaged with an exterior of the second threaded portion 542. The second moving block 48 further includes a portion serving as the second actuating element 42 that is engaged into the second engagement groove 311 of the second guide slider 31. Two ends of each of the first guide slider 21 and the second guide slider 31 are slidably mounted on the two guide rails 43 respectively. The first moving block 47 and the second moving block 48 can move linearly but cannot rotate.

[0140] In summary, the differences between the embodiment of FIG. 10 and the embodiment shown in FIGS. 8-9 are as follows. The first transmission rod 52 is provided with both the first and second threaded portions 522, 542, that are respectively threadedly engaged with the first threaded sleeve 472 and the second threaded sleeve 482. When the first transmission rod 52 is rotated clockwise or counterclockwise, it drives both the first threaded sleeve 472 and the second threaded sleeve 482 to slide, and the sliding direction of the first threaded sleeve 472 at the first threaded portion 522 is opposite to the sliding direction of the second threaded sleeve 482 at the second threaded portion 542.

[0141] In this way, the first transmission rod 52 can simultaneously drive the first threaded sleeve 472 and the second threaded sleeve 482 due to their engagements with the first threaded portion 522 and the second threaded portion 542, respectively, so that the first moving block 47 and the second moving block 48 in turn cause the first guide slider 21 of the first massage component 20 and the second guide slider 31 of the second massage component 30 to move towards or away from each other, thereby achieving the massage effect on the penis inserted into the accommodating space 10. The embodiment of FIG. 10 adopts fewer parts and components and therefore has higher structural reliability.

[0142] Similar to the embodiment shown in FIGS. 6-7, the first moving block 47 and the first guide slider 21 may be connected by other means or integrally formed as one single piece. The second moving block 48 and the second guide slider 31 may be connected by other means or integrally formed as one single piece. Details please refer to the above descriptions and will not be repeated again.

[0143] In the above embodiments, the first and second massage components are driven by a same motor with a same transmission assembly, and move simultaneously. It should be understood that, in other embodiments, the two massage components 20, 30 may be driven by two different actuators with respective individual transmission components. For example, FIG. 11 shows a yet alternative transmission component 40. In this embodiment, the transmission component 40 is arranged on a bottom side of the first and second massage components 20, 30, which is different from the above embodiments. In this embodiment, two motors 61, 62 are provided. Specifically, the actuator 60 includes a first motor 61 and a second motor 62. The first motor 61 and the second motor 62 are arranged on two longitudinal ends of the transmission component 40, respectively. The battery 82 is electrically connected to the circuit board 81. The circuit board 81 is electrically connected to the motors.

[0144] The transmission component 40 includes a first gear set 53 and a second gear set 55 respectively in torque-transmission connection with first motor 61 and the second motor 62. The transmission component 40 further includes a first transmission rod 52, a second transmission rod 54, a first moving block 47, a second moving block 48 and two guide rails 43 extending along the longitudinal direction and arranged in parallel along the lateral direction.

[0145] The first transmission rod 52 is provided with a first gear portion 521 and a first threaded portion 522. The first gear portion 521 is engaged with the first gear set 53, so that the first transmission rod 52 is driven by the first motor 61 to rotate through the first gear set 53.

[0146] The first moving block 47 includes a first threaded sleeve 472 threadedly engaged with an exterior of the first threaded portion 522. A portion of the first moving block 47 as the first actuating element 41 is engaged into the first engagement groove 211 of the first guide slider 21. The first moving block 47 can move linearly but cannot rotate. Due to the engagement between the first thread sleeve 472 and the first threaded portion 522, the first moving block 47 moves linearly as the first transmission rod 52 rotates.

[0147] The second transmission rod 54 is provided with a second gear portion 541 and a second threaded portion 542. The second gear portion 541 is engaged with the second gear set 55, so that the second transmission rod 54 is driven by the second motor 62 to rotate through the second gear set 55. That is, the first transmission rod 52 and the second transmission rod 54 are driven by the first motor 61 and the second motor 62, respectively and independently.

[0148] The second moving block 48 includes a second threaded sleeve 482 threadedly engaged with an exterior of the second threaded portion 542. A portion of the second moving block 48 as the second actuating element 42 is engaged into the second engagement groove 311 of the second guide slider 31. The second moving block 48 can move linearly but cannot rotate. Due to the engagement between the second thread sleeve 482 and the first threaded portion 542, the second moving block 48 moves linearly as the second transmission rod 54 rotates.

[0149] Two ends of each of the first guide slider 21 and the second guide slider 31 are slidably engaged with the two guide rails 43 respectively.

[0150] The working principle of the embodiment shown in FIG. 11 is basically the same as that of the embodiment of FIG. 10 described above, with the only difference in that the first and second massage components 20, 30 are driven to move towards or away from each other independently by means of the respective motors, gear sets, and threaded transmission pairs. The first massage component 20 is driven individually via the first motor 61, the first gear set 53, the first transmission rod 52, and the first moving block 47, and the second massage component 30 is driven individually via the second motor 62, the second gear set 55, the second transmission rod 54, and the second moving block 48. This structural design at least ensures that when one of the motors fails, the other motor is still able to drive the corresponding massage component to achieve the reciprocating movement, which in turn ensures that the first and second massage components 20, 30 continue to perform the movement that moves towards or away relative to each other, thereby improving the reliability of the male sexual stimulation device 100.

[0151] The present disclosure further provides an alternative embodiment, referring to FIGS. 12 to 19. In this embodiment, the first massage component 20 and the second massage components 30 that are linearly movable towards or away from each other are provided. This embodiment differs from the above embodiments in the structure of the first massage component 20.

[0152] In this embodiment, the first massage component 20 includes a first massage portion 24 and a second massage portion 25 respectively located at two opposite lateral sides of the first cavity 11. The first massage portion 24 and the second massage portion 25 are drivable to move towards or away from each other along a lateral direction that non-parallel the longitudinal direction.

[0153] In some embodiments, the male sexual stimulation device 100 further includes a pinch component 70. The pinch component 70 drives the first massage portion 24 and the second massage portion 25 to move towards or away from each other when the first massage component 20 is driven to slide by the transmission component 40. In this way, it is possible to increase or decrease the size of the space of the first cavity 11, so as to achieve a periodic pinching massage for the penis inserted into the first case 11.

[0154] During use, after the penis has been inserted into the accommodating space 10 constituted by the first cavity 11 of the first massage component 20 and the second cavity 12 of the second massage component 30, the actuator 60 can be started, which outputs a driving force to the transmission component 40 which drives the first and second massage components 20, 30 to move towards or away from each other, so that the first and second massage components are able to form stimulating effects of pinching and holding for penis.

[0155] During the operation, the first massage portion 24 and the second massage portion 25 of the first massage component 20 are driven to move towards or away from each other, so as to simultaneously pinch the penis inserted into the first cavity 11 for a better massage effect.

[0156] Referring to FIGS. 18 and 19, the structure of the transmission component 40 of this embodiment is similar to that provided in the embodiment of FIGS. 2-5. The transmission component 40 includes a drive gear 44, a first driven gear 45, and a second driven gear 46, a first eccentric rod 451, a second eccentric rod 461, and two guide rails 43 extending along the longitudinal direction and arranged in parallel along the lateral direction. The actuator 60 includes a motor. The battery 82 is electrically connected to the circuit board 81. The circuit board 81 is electrically connected to the motor.

[0157] The drive gear 44 is in torque-transmission connection with the actuator 60. The first and second driven gears 45, 46 are both engaged with the drive gear 44 and arranged on radially opposite sides of the drive gear 44. The first eccentric rod 451 is fixed on the first driven gear 45 and slidably arranged within the first engagement groove 211 of the first guide slider 21. The second eccentric rod 461 is fixed on the second driven gear 46 and slidably arranged within the second engagement groove 311 of the second guide slider 31. Two sides of the second guide slider 31 are slidably mounted to the two guide rails 43 respectively. That is, the first eccentric rod 451 fixed on the first driven gear 45 serves as the first actuating element 41, a second eccentric rod 461 fixed on the second driven gear 46 serves as the second actuating element 42.

[0158] This embodiment differs from the first embodiment in that, referring to FIGS. 14 and 16, the transmission component 40 further includes a first bevel gear 56 and a second bevel gear 57. The first bevel gear 56 is connected to a drive shaft of the motor. The second bevel gear 57 is engaged with the first bevel gear 56 and is coaxially connected to the drive gear 44. Thus, the rotational power output from the motor is transferred to the second bevel gear 57 through the first bevel gear 56, and the second bevel gear 57 brings the drive gear 44 to rotate together, which can drive the first and second driven gears 45, 46 meshing with the drive gear 44 to rotate simultaneously. By means of the gear transmission, the transmission ratio can be made stable, the transmission of the power can be smooth, and it can effectively ensure that the first massage component 20 and the second massage component 30 accurately move towards or away from each other, thereby ensuring the massage effect on the penis.

[0159] In this embodiment, referring to FIGS. 14, 15 and 17, one end of the first massage portion 24 and one end of the second massage portion 25 are connected to two ends of the first guide slider 21, respectively. The first massage portion 24 and the second massage portion 25 are spaced apart from each other to enclose the first cavity 11. The pinch component 70 is configured to be movable and connected to at least one of the first and second massage portions 24, 25. So that at least one of the first and second massage portions 24, 25 is able to move towards or away from the center of the first cavity 11 to decrease or increase the space of the first cavity 11 under the actuation of the pinch component 70.

[0160] To ensure comfort during the penis pinching, both the first massage portion 24 and the second massage portion 25 are made of flexible materials, such as rubber, silicone, foam, or the like.

[0161] Specifically, there may be a variety of implementations that enable the reciprocating movements of the first and second massage portions 24, 25 towards or away from the center of the first cavity 11. For example, the pinch component 70 may adopt an inflatable airbag, and the expansion or contraction of the airbag can drive the first massage portion 24 and/or the second massage portion 25 to move. Alternatively, the pinch component 70 may employ a sliding component, which drives the first and second massage portions 24, 25 to slide towards or away from the center of the first cavity 11, or the like.

[0162] In particular, in this embodiment, the pinch component 70 includes a first swing rod 71, a second swing rod 72, a first actuating block 73, and a second actuating block 74. The first actuating block 73 and second actuating block 74 are respectively provided with a first inclined slot 731 and a second inclined slot 741. The extension directions of the first and second inclined slots 731, 741 are both inclined at an angle relative to the longitudinal direction. The extension directions of the first and second inclined slots 731, 741 may be parallel to each other.

[0163] The first swing rod 71 and the second swing rod 72 are slidably and rotatably mounted around the two guide rails 43 respectively.

[0164] Specifically, the first swing rod 71 includes a first tubular body 713 slidably mounted around one guide rail 43, a first swing arm 711 and a first guide arm 712 extending outwardly from the first tubular body 713. The first swing arm 711 and the first guide arm 712 extend in different directions. The first swing arm 711 passes through the first guide slider 21 and extends into the first massage portion 24. The first guide arm 712 is slidably engaged in the first inclined slot 731.

[0165] Similarly, the second swing rod 72 includes a second tubular body 723 slidably mounted around one guide rail 43, a second swing arm 721 and a second guide arm 722 extending outwardly from the second tubular body 723. The second swing arm 721 and the second guide arm 722 extend in different directions. The second swing arm 721 passes through the first guide slider 21 and extends into the second massage portion 25. The second guide arm 722 is slidably engaged in the second inclined slot 741.

[0166] When the first actuating element 41 drives the first guide slider 21 to reciprocate along the longitudinal direction, the first guide slider 21 drives the first swing rod 71 and the second swing rod 72 to slide along the longitudinal direction. As the first and second swing rods 71, 72 slide, the first guide arm 712 slides in the first inclined slot 731, and the second guide arm 722 slides in the second inclined slot 741. Due to the inclination of the slots 731, 741, when the first swing rod 71 and the second swing rod 72 slide in the longitudinal direction, the first and second guide arms 712, 722 slide inclinedly, which cause the first and second guide arms 712, 722 rotate about the guide rails 43, and in turn the first and second swing arms 711, 721 swing towards or away from each other.

[0167] Specifically, during the movement of the first massage component 20 along the guide rail 43 away from the second massage component 30, the first guide arm 712 and the second guide arm 722 simultaneously slide from the low point to the high point along the first inclined slot 721 and the second inclined slot 741, respectively. The first swing arm 711 and the second swing arm 721 rotate towards each other, with the central axis of the corresponding guide rail 43 as the axis of rotation. So that the first swing arm 711 and the second swing arm 721 drive the first massage portion 24 and the second massage portion 25, respectively, to move towards the center of the first cavity 11, thereby applying a pinching massage effect on the penis.

[0168] During the movement of the first massage component 20 along the guide rail 43 towards the second massage component 30, the first guide arm 712 and the second guide arm 722 simultaneously slide from the high point to the low point along the first inclined slot 721 and the second inclined slot 741, respectively. The first swing arm 711 and the second swing arm 721 rotate away from each other, with the central axis of the corresponding guide rail 43 as the axis of rotation. Consequently, the first swing arm 711 and the second swing arm 721 drive the first massage portion 24 and the second massage portion 25, respectively, to move apart, thereby releasing the pinching effect on the penis. Thus, in this embodiment, the first massage component 20 actually has two massage modes which are longitudinal sliding massage and lateral pinching massage, thereby further enhancing the massage effect.

[0169] In this embodiment, the structure of the second massage component 30 is the same as that in the embodiment shown in FIGS. 2-5, and therefore will not be repeated here.

[0170] In this embodiment, the movement of the first massage component 20 along the guide rail 43 away from the second massage component 30 causes the first massage portion 24 and the second massage portion 25 to move towards each other in the lateral direction; and the movement of the first massage component 20 along the guide rail 43 towards the second massage component 30 causes the first massage portion 24 and the second massage portion 25 to move away from each other in the lateral direction. However, it should be understood that, in other embodiments, the relationship between the longitudinal movement of the first massage component 20 relative to the second massage component 30 and the lateral movements of the first and the second massage portions 24, 25 may be opposite to that in this embodiment, by changing the extension direction of the inclined slots.

[0171] In some embodiments, at least one of the first massage portion 24 and the second massage portion 25 is provided with at least one vibration component 80. The vibration component 80 may be a vibration motor. Preferably, each of the first massage portion 24 and the second massage portion 25 is provided with one vibration component 80 installed inside. During the pinching massage applied by the first and second massage portions 24, 25 on the penis, the at least one vibration component 80 simultaneously applies a vibration effect on the penis, further improving the massage effect. In other embodiments, the second massage component 30 is also provided with the at least one vibration component 80 to further enhance the massage effect on the penis.
