[0061] Embodiments of the present disclosure will be described in detail below. The embodiments described with reference to the accompanying drawings are merely examples. An electronic-cigarette vaporization component 100 according to an embodiment of a first aspect of the present disclosure will be described below with reference to FIG. 1 to FIG. 12.

[0062] As shown in FIG. 1 to FIG. 12, the electronic-cigarette vaporization component 100 according to the embodiment of the first aspect of the present disclosure includes a housing 1 and a vaporization core fixing device 2. The housing 1 has a liquid storage cavity 111 provided therein, an outlet channel 112, and a vaporization cavity 113 in communication with the outlet channel 112. An air inlet 121 in communication with the vaporization cavity 113 and an air outlet 114 in communication with the outlet channel 112 are provided on the housing 1. The vaporization core fixing device 2 is fixed in the housing 1, i.e., the vaporization core fixing device 2 is fixedly connected with the housing 1. The fixed connection may be that the vaporization core fixing device 2 presses against an inner side wall of the housing 1. The vaporization core fixing device 2 separates the liquid storage cavity 111 and the vaporization cavity 113, and the vaporization core fixing device 2 is formed with a mounting groove 211 and a communication channel 23. The mounting groove 211 is separated from the communication channel 23. A first end of the communication channel 23 is in communication with the vaporization cavity 113, and a second end of the communication channel 23 is in communication with one end of the outlet channel 112 distant from the air outlet 114. At least a portion of the communication channel 23 is arranged obliquely with respect to the outlet channel 112. A vaporization core component 4 is arranged in the mounting groove 211. The vaporization core component 4 is in communication with the liquid storage cavity 111 and the vaporization cavity 113 respectively. The vaporization core component 4 is configured to heat and vaporize an e-liquid in the liquid storage cavity 111 to form an aerosol into the vaporization cavity 113. A user inhales through the air outlet 114. Outside air enters the vaporization cavity 113 through the air inlet 121, and is mixed with the aerosol in the vaporization cavity 113, for inhalation by the user through the outlet channel 112.

[0063] For example, in the example of FIG. 1 and FIG. 2, the outlet channel 112 may be arranged in a middle part of the housing 1, the liquid storage cavity 111 is located on an outer peripheral side of the outlet channel 112, and the liquid storage cavity 111 is configured to store the e-liquid. The vaporization core fixing device 2 is fixed in the housing 1, and the vaporization core fixing device 2 is located on one side of the outlet channel 112 close to the air inlet 121. The vaporization core component 4 is fixedly mounted in the mounting groove 211, and a shape of the mounting groove 211 matches a shape of the vaporization core 9, so as to firmly mount the vaporization core 9 on the vaporization core fixing member 2. The vaporization cavity 113 is located on one side of the vaporization core fixing device 2 distant from the liquid storage cavity 111. The e-liquid in the liquid storage cavity 111 may be heated and vaporized by the vaporization core component 4 to form an aerosol, which enters the vaporization cavity 113. The air outlet 114 is provided at a center of a top of the housing 1. The air outlet 114 is in communication with the outlet channel 112. The air inlet 121 is provided at a bottom of the housing 1 and is in communication with the vaporization cavity 113. During inhalation by the user, outside air enters the vaporization cavity 113 through the air inlet 121.

[0064] As shown in FIG. 3 to FIG. 5, because the communication channel 23 is provided on the vaporization core fixing device 2, and at least a part of the communication channel 23 is arranged obliquely with respect to the outlet channel, the aerosol in the vaporization cavity 113 can smoothly flow to the outlet channel 112 and be inhaled through the air outlet 114, and the space required for arranging the communication channel is also reduced, thereby achieving the miniaturization design of the electronic-cigarette vaporization component.

[0065] According to an embodiment of the present disclosure, the first end of the communication channel 23 is located between the mounting groove 211 and an inner side wall of the housing 1, and a central axis of the first end of the communication channel 23 is closer to the inner side wall of the housing 1 than a central axis of the outlet channel 112 is. With such an arrangement that the communication channel 23 is arranged on the vaporization core fixing device and one end of the communication channel 23 in communication with the vaporization cavity 113 is located on one side of the mounting groove 211, the communication channel 23 of the present disclosure can save space and facilitate the miniaturization design of the electronic-cigarette vaporization component, compared with the arrangement of a separate channel for communicating the vaporization cavity 113 with the outlet channel 112 in the prior art. Moreover, compared with the arrangement of a zigzag communication channel and a curved communication channel in the prior art, the communication channel of the present disclosure makes the aerosol flow more smoothly during inhalation.

[0066] According to an embodiment of the present disclosure, the housing has a length direction, a width direction, and a thickness direction, a maximum dimension of the housing in the length direction is larger than a maximum dimension of the housing in the width direction, and the maximum dimension of the housing in the width direction is larger than or equal to a maximum dimension of the housing in the thickness direction. As shown in FIG. 1 to FIG. 2, the length direction of the housing 1 is defined as a direction B, the width direction of the housing 1 is defined as a direction A, and the thickness direction of the housing 1 is perpendicular to the length direction and the width direction, that is, the length direction, the width direction, and the thickness direction of the housing 1 are perpendicular to each other. According to an embodiment of the present disclosure, the maximum dimension of the housing 1 in the thickness direction is smaller than the maximum dimension of the housing 1 in the width direction, that is, the maximum dimension of the housing 1 in the thickness direction is the smallest, the housing 1 is flat, and the maximum dimension of the housing 1 in the length direction and the maximum dimension of the housing 1 in the width direction depend on actual situations. When the vaporization device 100 is used in an electronic cigarette as a cartridge, the length direction is generally the same as the length direction of the cigarette rod, i.e. the length direction is an extending direction from the cartridge to the cigarette rod.

[0067] According to an embodiment of the present disclosure, as shown in FIG. 4 to FIG. 6, the first end of the communication channel 23 is in communication with the vaporization cavity 113, and the first end of the communication channel 23 is staggered from the mounting groove 211 in the width direction of the housing 1, that is, the first end of the communication channel 23 is located on one side of the mounting groove 211 in the width direction of the housing 1, and at least a part of the communication channel 23 is inclined with respect to the outlet channel 112 in the width direction of the housing 1. The structural design where the end of the communication channel 23 in communication with the vaporization cavity 113 is provided on one side of the mounting groove 211 in the width direction and at least a part of the communication channel 23 extends toward an end of the outlet channel 112 distant from the air outlet 114 in the width direction of the housing 1 to form a communication connection allows for a smaller thickness of the housing 1 and is more in line with the user's usage habit, as compared with the arrangement of a channel for communicating the vaporization cavity 113 with the outlet channel 112 in the thickness direction of the housing 1.

[0068] According to an embodiment of the present disclosure, as shown in FIG. 4 to FIG. 6, the communication channel 23 includes a second channel segment 231 and a second connecting segment 232 in communication with each other, and the second channel segment 231 extends obliquely in the width direction of the housing 1 toward an end of the outlet channel 112 distant from the air outlet 114, that is, the second channel segment 231 is inclined in the width direction with respect to the outlet channel 112. The second connecting segment 232 is sleeved on an outer peripheral side of the end of the outlet channel 112 distant from the air outlet 114. That is, the second channel segment 231 of the communication channel 23 and the mounting groove for mounting the vaporization core component 4 are arranged in the width direction of the housing 1, and in the width direction of the housing 1, and the second channel segment 231 of the communication channel 23 extends obliquely from the vaporization core fixing device 2 toward the outlet channel 112 and is in communication with the outlet channel 112. In other words, in the width direction of the housing 1, a central axis of the second channel segment 231 forms an acute angle with the central axis of the outlet channel 112. The aerosol in the vaporization cavity 113 enters the outlet channel 112 through the communication channel 23, and the communication channel 23 does not occupy space in the thickness direction of the housing 1, so that an ultra-thin design of the housing 1 can be achieved to meet user requirements. In addition, the second channel segment 231 of the communication channel 23 is arranged obliquely in the width direction of the housing 1 with respect to the outlet channel 112, so that the aerosol in the vaporization cavity 113 can smoothly enter the outlet channel 112, thereby reducing the resistance to inhalation of the electronic cigarette, and improving user experience.

[0069] The electronic-cigarette vaporization component 100 of the present disclosure needs to be used with a cigarette rod when used in an electronic cigarette. The user inhales through the air outlet 114. In this case, a pneumatic sensor (for example, an airflow sensor) in the cigarette rod detects the inhalation, and a power source in the cigarette rod is electrically connected to the vaporization core module 4. The vaporization core module 4 starts heating. During this process, the e-liquid in the liquid storage cavity 111 is guided to the vaporization core module 4 to be heated and vaporized to form an aerosol, which enters the vaporization cavity 113. At the same time, outside air enters the vaporization cavity 113 through the air inlet 121 and is mixed with the aerosol in the vaporization cavity 113. The mixture enters the outlet channel 112 through the communication channel 221 and reaches the air outlet 114 for inhalation by the user. When the user stops inhaling through the air outlet 114, the electrical connection between the power source in the cigarette rod and the vaporization core component 4 is disconnected, and the power source stops supplying power to the vaporization core component 4. It needs to be explained herein that in some electronic cigarettes, the electronic-cigarette vaporization component 100 and the cigarette rod are configured as separate structures, which can be combined detachably, and in some electronic cigarettes, the electronic-cigarette vaporization component 100 and the cigarette rod are configured as a non-detachable structure. This is not specifically limited herein.

[0070] According to some embodiments of the present disclosure, an included angle between a central axis of the second channel segment 231 and the central axis of the outlet channel 112 ranges from 20° to 70°, and a central axis of the second connecting segment 232 coincides with the central axis of the outlet channel 112. When the included angle between the central axis of the second channel segment 231 and the central axis of the outlet channel 112 is controlled to 20°-70°, the resistance to inhalation of the electronic cigarette is minimized while satisfying the ultra-thin design of the electronic-cigarette vaporization component 100. Therefore, the flow rate of the e-liquid can be slowed down to reduce the formation of condensate such as e-liquid, to prevent the user from breathing into the e-liquid in liquid form, providing a better user experience.

[0071] According to an embodiment of the present disclosure, as shown in FIG. 4 to FIG. 6, the vaporization core fixing device 2 includes a fixing portion 21 and a channel portion 22.

That is to say, the channel portion 22 is in communication with the vaporization cavity 113 through the communication hole 212 provided on the fixing portion 21. According to an embodiment of the present disclosure, the fixing portion 21 and the channel portion 22 are of an integrated structure.

[0074] According to an embodiment of the present disclosure, a connecting wall is connected between a side wall of the second connecting segment 232 and a side wall of the second channel segment 231, the connecting wall and the side wall of the second connecting segment 232 are perpendicular to each other, the connecting wall forms an angle with the side wall of the second channel segment 231, and an end surface of the end of the outlet channel 231 distant from the air outlet 114 presses against the connecting wall. According to an embodiment of the present disclosure, the end surface of the end of the outlet channel 112 distant from the air outlet 114 presses against the connecting wall in the length direction of the housing 1.

A side surface of the vaporization portion 4112 distant from the liquid guiding portion 4111 is a vaporization surface. The heating element 412 is arranged on the vaporization surface. The projected area of the liquid guiding portion 4111 is smaller than the projected area of the vaporization portion 4112 in the direction perpendicular to the length direction of the housing 1. According to an embodiment of the present disclosure, in the vaporization core component 4, the liquid absorption surface is arranged opposite to the vaporization surface, and an area of the liquid absorption surface is smaller than an area of the vaporization surface, so that the e-liquid absorbed by the liquid absorption surface can fully penetrate into the surface of the vaporization region on the vaporization surface, to prevent the e-liquid absorbed by the liquid absorption surface from gathering in the region outside the vaporization region on the vaporization surface and being inhaled by the user due to excessively quick penetration.

When the pressure in the vaporization cavity 113 is greater than the pressure in the liquid storage cavity 111, the air exchange channel is opened under the pressure difference between the vaporization cavity 113 and the liquid storage cavity 111 to reduce the pressure in the vaporization cavity 113, so that the e-liquid in the liquid storage cavity 111 can smoothly flow to the vaporization core component 4. When the pressure in the vaporization cavity 113 is not greater than the pressure in the liquid storage cavity 111, indicating a pressure balance between the liquid storage cavity 111 and the vaporization cavity 113, the air exchange channel is closed, to prevent the e-liquid in the liquid storage cavity 111 from entering the vaporization cavity through the air exchange channel, i.e., to prevent e-liquid leakage. Therefore, the pressure difference between the liquid storage cavity 111 and the vaporization cavity 113 can be effectively adjusted through the air exchange channel, so that the pressure in the liquid storage cavity 111 can be greater than the pressure in the vaporization cavity 113, to ensure that the e-liquid can smoothly flow to the vaporization core component 4 and be effectively vaporized.

By such a configuration, when the e-liquid in the liquid storage cavity 111 flows into the air exchange groove 216 and enters the vaporization cavity 113 through the air exchange through hole 215, the flow of the e-liquid from the air exchange groove 216 to the air exchange through hole 215 is from a “lower position” to a “higher position” because the air exchange through hole 215 is at a higher position and is closer to the liquid storage cavity 111. In this way, the e-liquid in the liquid storage cavity 111 can be prevented from flowing into the vaporization cavity 113 through the air exchange groove 216 and the air exchange through hole 215, thereby preventing the e-liquid from being inhaled by the user.
