HAIR STYLING ATTACHMENT

[0001] This application claims priority to Chinese Patent Application No. 202610138354.5, filed on January 31, 2026, which is hereby incorporated by reference in its entirety.

[0002] The present disclosure belongs to the technical field of hairdressing technology, and in particular to a hair styling attachment.

[0003] Conventional hair styling (especially curling) typically involves multiple separate steps: first, wet hair needs to be roughly dried with a hair dryer, and a curling iron or roller is then used to manually wind the hair for heat setting. Existing curling devices that rely on manual winding or mechanical clamping mechanisms easily cause hair pulling and friction, resulting in cuticle damage and hair breakage.

[0004] Moreover, although some automatic hair curlers can achieve rotational winding, they still depend on clamping plates or toothed structures to physically fix an end portion of the hair, failing to fundamentally resolve the problems of pulling damage and operational complexity. Therefore, there is an urgent market need for a hair styling tool that integrates drying and styling, is easy to operate, and can protect hair to the greatest extent.

[0005] The present disclosure provides a hair styling attachment, which is intended to eliminate mechanical pulling and friction on hair caused by clips, teeth, and the like of conventional curling irons, thereby achieving damage-free styling.

[0006] The present disclosure provides a hair styling attachment, including a styling body, where an air cavity is formed inside the styling body, and the styling body has a styling surface for contacting hair;

[0007] an air-guiding structure disposed on the styling body and being in communication with the air cavity;

[0008] where the air-guiding structure is configured to form a negative-pressure adsorption zone near the styling surface when a fluid flows through the air cavity, thereby causing the hair to be adsorbed onto the styling surface; and

[0009] the styling body is configured to make relative rotational movement with the hair adsorbed onto the styling surface, such that the hair is wound around the styling body.

[0010] Further, the air-guiding structure is provided with an air-guiding chamber in communication with the air cavity and an air outlet formed in the air-guiding chamber, and the air outlet is configured to guide the fluid toward the styling surface.

[0011] Further, the air-guiding structure further includes a connecting portion and an air-guiding portion in communication with the air-guiding chamber, the connecting portion is provided with a second inclined surface, the air-guiding portion is provided with a first inclined surface, the first inclined surface forms an angle A with a central axis L1 of the air-guiding structure, and the second inclined surface forms an angle B with the central axis L1 of the air-guiding structure.

[0012] Further, the angle A is greater than 30° and less than 75°, and the angle B is greater than 15° and less than 60°.

[0013] Further, the air-guiding structure has a configuration symmetrically arranged about its own central axis L1, such that two air outlets are formed in a symmetrical arrangement, thereby forming two symmetrical negative-pressure adsorption zones on the styling surface.

[0014] Further, the styling surface is provided with a plurality of comb teeth arranged in an array along the styling body, and gaps for accommodating the hair are formed between adjacent comb teeth.

[0015] Further, the hair styling attachment further includes a guide member disposed within the air cavity and rotatably connected to the styling body, where an opening is formed in a side wall of the guide member, and an air inlet in communication with the air-guiding structure is formed in the styling body; and a position of the opening relative to the air inlet is changed by rotating the guide member, thereby adjusting distribution of the fluid.

[0016] Further, a rotatable groove is formed on the styling body, the guide member includes a flow-guiding portion, and a projection adapted to the rotatable groove is disposed on the flow-guiding portion; and by rotating a rotatable portion of the guide member, the projection moves along a trajectory of the rotatable groove, thereby limiting orientation of the opening to rotate between a first position and a second position.

[0017] Further, the rotatable groove is arcuate.

[0018] Further, a plurality of air-guiding structures are provided, and are arranged in an array along an axial direction of the styling body.

[0019] Compared with the prior art, the present disclosure has the beneficial effects:

[0020] The present disclosure innovatively provides air-guiding structures of specific configurations on the styling body, and employs the Bernoulli's principle and the Coandă effect to form stable negative-pressure adsorption zones near the styling surface through the high-speed outflowing air, thereby replacing conventional mechanical clamping or manual winding, achieving gentle, damage-free adsorption fixation of hair, and integrating negative-pressure adsorption, rotational winding, and hot air (or cold air) blowing/setting functions into a single attachment. When adsorption occurs, the airflow immediately begins to dry and heat the hair directly attached to the surface, thereby realizing an efficient process of “styling starting upon adsorption.” The operation is simple. The user only needs to bring the hair tips close to the styling surface to achieve automatic adsorption, and then complete winding through simple rotation (manual or automatic operation), thereby reducing the difficulty of operation.

[0036] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments acquired by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present disclosure.

[0037] As shown in FIGS. 1-4, the present disclosure provides a hair styling attachment, including a styling body 1 and an air-guiding structure 2 disposed on the styling body 1. An air cavity 11 is formed inside the styling body 1, and the air-guiding structure 2 is in communication with the air cavity 11. When a fluid flows through the air cavity 11, the air-guiding structure 2 is capable of forming a negative-pressure adsorption zone near a styling surface 12 of the styling body 1, such that hair 3 is adsorbed onto the styling surface 12 for drying to achieve a drying effect. Specifically, the styling body 1 is configured to allow relative rotational movement with the hair 3 attached to its outer peripheral surface, thereby causing the hair 3 to be wound around the styling body 1. By guiding hot air to the styling surface 12 through the air-guiding structure 2, drying and heat setting are performed directly while adsorbing the hair 3, thereby significantly saving styling time.

[0038] When in use, as shown in FIG. 3, a user mounts the hair styling attachment onto a main unit, and turns on the main unit. The main unit is a hair dryer. The fluid, typically hot air or cold air, is driven by a fan of the main unit to flow into the air cavity 11 inside the styling body 1. A strand of hair 3 is taken by a user, and its hair tip 31 is placed close to or gently against an outer peripheral surface of the styling surface 12 of the styling body 1, in which case, a high-speed airflow ejected from the air-guiding structure 2 blows toward the styling surface 12. According to Bernoulli's principle and Coandă effect, the high-speed airflow flowing closely along the styling surface 12 generates the significant negative-pressure adsorption zone around the styling surface. Under the action of the negative pressure, the hair tip 31 located near the styling surface 12 is gently adsorbed and attached to the styling surface 12, the adsorption force replaces the method of manually winding or fixing with clips in conventional curling irons, avoiding damage to the hair 3 caused by manual pulling, achieving damage-free styling, and ensuring that an end portion of the hair 3 is in close contact with the styling surface, with simple and convenient operation, saving time and improving curling efficiency.

[0039] As shown in FIG. 4, the hot air continuously flowing through the air cavity 11 transfers its thermal energy directly to the tightly attached hair 3 through a wall surface of the styling body 1, directly acting on each section of wet hair that has just been wound onto the styling surface 12, using its velocity and heat to rapidly disperse and carry away moisture on the hair 3, drying the hair 3. The user keeps a hair root 32 of the hair 3 substantially stationary while manually operating the styling body 1, or the styling body 1 automatically begins to rotate about its own axis under motor drive. Since the hair tip 31 has been firmly adsorbed onto the styling surface 12 by negative pressure, when the styling body 1 rotates, the hair 3 is automatically and uniformly spirally wound along the outer peripheral surface of the styling body 1. A winding direction is from the hair tip 31 to the hair root 32, that is, the rotational movement causes the already adsorbed hair tip 31 to first serve as a fixed starting point, and subsequent hair sections are tightened and wound onto the styling body 1 section by section.

[0040] As shown in FIG. 5, during the winding process, the air-guiding structure 2 continuously operates, and the negative-pressure adsorption zone exists at all times, ensuring that the wound hair 3 is continuously attached to the styling surface 12 without loosening. In addition, when the fluid flowing through the air cavity 11 is hot air, it uniformly and efficiently heats and sets the tightly attached hair 3, or when the fluid is cold air, it performs cooling setting.

[0041] As shown in FIG. 5, after the hair 3 is wound to a desired position, the user may maintain this state for a short period, and continuous hot air is used to complete final setting and thorough drying. Thereafter, cold air may be switched on for cooling and setting to lock the hairstyle. After the fluid is turned off or a flow rate is reduced, the negative pressure disappears, thus the user can easily remove the formed curl from the styling body 1, obtaining a curled hairstyle with uniform and elastic curls from the hair root to the hair tip 31.

[0042] Specifically, as shown in FIG. 6, the air-guiding structure 2 is provided with an air-guiding chamber 24 in communication with the air cavity 11, and an air outlet 21 is formed in the air-guiding chamber 24. The styling surface 12 is an outer peripheral surface of the styling body 1. The air outlet 21 is configured to guide fluid toward the styling surface 12 of the styling body 1, such that a negative-pressure adsorption zone is formed on the styling surface 12. When the air outlet 21 blows fluid, such as air, at a high speed toward the outer peripheral surface of the styling body 1, the airflow flows closely against the surface, forming a low-pressure zone, that is, the negative-pressure adsorption zone. The negative-pressure adsorption zone may adsorb the hair 3, thereby achieving adsorption fixation or other functions.

[0043] Preferably, the air-guiding structure 2 may be configured as conical, triangular, columnar, cylindrical, or the like. In this embodiment, the air-guiding structure 2 is columnar.

[0044] In one embodiment, the air-guiding structure 2 may be disposed obliquely on the styling body 1.

[0045] As shown in FIG. 7, in another embodiment, a central axis L1 of the air-guiding structure 2 is perpendicular to a central axis L2 of the styling body 1.

[0046] Specifically, as shown in FIGS. 6 and 8, when the air-guiding structure 2 is cylindrical, the air-guiding structure 2 includes a connecting portion 22 and an air-guiding portion 23 that are integrally formed. The air-guiding portion 23 is disposed at an end away from the styling surface 12. The air-guiding portion 23 includes a first inclined surface 231, and the connecting portion 22 is provided with a second inclined surface 221. The first inclined surface 231 forms an included angle A with the central axis L1 of the air-guiding structure 2, the second inclined surface 221 forms an included angle B with the central axis L1 of the air-guiding structure 2, the two inclined surfaces are arranged opposite to each other, and the first inclined surface 231 and the second inclined surface 221 may be arranged parallel to each other or formed into an acute angle, together forming a guiding flow channel.

[0047] During operation, as shown in FIGS. 6-8, airflow enters the air-guiding structure 2 from the air cavity 11 and flows toward the air-guiding portion 23 at its end. The airflow is first guided by the first inclined surface 231 to change direction to flow toward the styling surface 12. Subsequently, the second inclined surface 221 further constrains and guides the airflow. Under the combined action of the two inclined surfaces, the airflow flows through the flow channel formed between them and is finally blown from the air outlet 21 toward the styling surface 12 of the styling body 1 in a concentrated way at a specific angle.

[0048] Preferably, the angle A is greater than 30° and less than 75°, and the angle B is greater than 15° and less than 60°. Within these ranges, the angles of the inclined surfaces ensure that the airflow obtains sufficient lateral guiding components to effectively blow toward the styling surface 12 while maintaining smooth transition, avoiding excessive flow resistance and vortices caused by abrupt angle changes, thereby achieving efficient and stable guiding and flowing effects.

[0049] In this embodiment, a cross section of the air-guiding portion 23 is triangular, and the air-guiding structure 2 is symmetrically arranged along its own central axis L1, that is, one air-guiding structure 2 includes two air outlets 21, and two first inclined surfaces 231 and two second inclined surfaces 221. Based on this structure, after entering the air-guiding structure 2, the airflow from the air cavity 11 is naturally divided into two streams by the internal symmetrical structure. The two streams then respectively enter elongated flow channels on both sides, are accelerated and directed under the constraint and guidance of the first inclined surfaces 231 and the second inclined surfaces 221, and finally are ejected from the air outlets 21 on the side walls downward at a certain included angle at a high speed and symmetrically toward the styling surface 12. The dual air outlet structure expands an effective action area and achieves more uniform hot air coverage, which helps to improve drying and setting speed and consistency of styling effects, and simultaneously forms two symmetrical negative-pressure adsorption zones on the styling surface 12. This not only enables the hair 3, especially thicker hair bundles, to be adsorbed and attached to the styling surface 12 more quickly and evenly from both sides, but also fundamentally prevents twisting or deviation of the hair 3 due to unilateral force during adsorption and winding, ensuring smooth and stable winding action.

[0050] Preferably, the air-guiding structure 2 may be detachably connected, snap-fitted, bonded, screwed, magnetically connected to the styling surface 12, or integrally injection-molded with the styling body 1. In this embodiment, the air-guiding structure 2 is integrally injection-molded with the styling body 1.

[0051] Specifically, as shown in FIG. 7, the air-guiding structures 2 are arranged in an array along the central axis L2 of the styling body 1, such that the dual-side airflow effect is continuously distributed along an axial direction of the styling body 1. This creates a series of uniform and stable negative-pressure adsorption zones across the entire styling surface 12, thereby achieving efficient and balanced adsorption and attachment of more and longer hair bundles. The symmetrical and continuous force field distribution further ensures that the hair 3 is subjected to uniform force during winding, effectively preventing twisting and deviation, and ensuring smooth styling, and stable and consistent setting effects.

[0052] In addition, the two air-guiding structures 2 are symmetrically arranged along the central axis L2 of the styling body 1 in upper and lower directions, that is, they are respectively disposed on an upper side and a lower side of the styling body 1.

[0053] The air-guiding structures 2 are arranged adjacent to each other at certain intervals on the styling surface 12. The styling surface 12 serves as an outer peripheral working surface of the styling body 1 and is configured to support the hair 3.

[0054] In addition, as shown in FIG. 7, in order to further optimize the distribution, positioning, and heat transfer of the hair 3 during styling and to improve the uniformity and efficiency of styling, a plurality of comb teeth 4 are further arranged on the styling surface 12 in an array along the axial direction of the styling body 1. These comb teeth 4 are arranged at certain intervals, and gaps 41 for accommodating the hair 3 are formed between adjacent comb teeth 4. This naturally separates the hair bundles, preventing mutual entanglement or knotting during winding, thereby achieving the management of hair bundles at a physical level.

[0055] In addition, the comb teeth 4 increase contact points and support points between the styling surface 12 and the hair 3, which not only more stably supports the hair 3 but also facilitates more uniform transfer of heat or cold to the hair 3 through contact conduction. Moreover, the gaps 41 between the comb teeth 4 form natural airflow channels, wall-attached airflow ejected from the air-guiding structures 2 can flow along these natural airflow channels, such that the negative-pressure effect can act not only on a side of the hair 3 facing the styling surface 12, but also penetrate between the hair bundles, thereby producing a more three-dimensional and more secure adsorption effect.

[0056] Further, as shown in FIGS. 9-10, the attachment further includes a guide member 5. The guide member 5 is disposed inside the air cavity 11 and is rotatably connected to the air cavity 11. The guide member 5 further includes an air inlet chamber 56. The guide member 5 is connected to a hair dryer main body, and the guide member 5 receives hot air or cold air from the hair dryer main body through the air inlet chamber 56.

[0057] Specifically, as shown in FIGS. 9-10, the guide member 5 is provided with an opening 51, and the styling body 1 is internally provided with an air inlet 13. The air inlet 13 is in communication with the air-guiding structures 2, and the opening 51 is in communication with the air inlet 13. During operation, airflow from the hair dryer main body blows toward the guide member 5 and then enters the air cavity 11 through the opening 51, and further flows to the air-guiding structures 2 through the air inlet 13.

[0058] Preferably, the guide member 5 is cylindrical.

[0059] Further, as shown in FIG. 10, the guide member 5 includes a flow-guiding portion 52 located inside the air cavity 11 and a rotatable portion 53 extending outside the air cavity 11, and the opening 51 is provided on the flow-guiding portion 52. When in use, an orientation of the opening 51 on the flow-guiding portion 52 may be adjusted by rotating the exposed rotatable portion 53.

[0060] Embodiment 1: The opening 51 is circumferentially arranged along an entire circumferential wall of the flow-guiding portion 52. This configuration enables the airflow to uniformly flow to all air-guiding structures 2, thereby achieving balanced air supply on an entire circumference.

[0061] Embodiment 2: The opening 51 is arranged only on half of the circumferential wall of the flow-guiding portion 52, while the other half of the circumferential wall is in a sealed state. By rotating the rotatable portion 53, a circumferential position of the opening 51 may be changed, thereby selectively guiding the airflow to portions of the air-guiding structures 2 corresponding to the opening 51, achieving partitioned or directional air supply. In the present disclosure, the opening 51 of the guide member 5 is configured as in Embodiment 2.

[0062] Further, as shown in FIG. 11, an arcuate rotatable groove 14 is formed at an end of the styling body 1 away from the air inlet 13. A projection 521 adapted to the rotatable groove 14 is disposed on a side wall of the corresponding position of the flow-guiding portion 52. By rotating the rotatable portion 53, the projection 521 moves along an arcuate trajectory of the rotatable groove 14, thereby limiting the orientation of the opening 51 to rotate between a first position 54 and a second position 55.

[0063] As shown in FIG. 12, in the first position 54, the opening 51 directly faces and is in full communication with the air-guiding structures 2 on the upper side or a designated side of the styling body 1, and the airflow is entirely blown out through the air-guiding structure 2 on the side, achieving concentrated air supply on a single side.

[0064] As shown in FIG. 13, in the second position 55, the orientation of the opening 51 is in an intermediate state, and the airflow is divided into two parts, respectively flowing to and communicating with the air-guiding structures 2 on the upper and lower sides, thereby achieving simultaneous balanced air supply on both sides.

[0065] Specifically, as shown in FIGS. 2 and 14, the attachment further includes a first snap-fit block 6, which is designed to provide stable support for the rotatable portion 53 and define its installation position.

[0066] Specifically, as shown in FIGS. 2 and 14, the first snap-fit block 6 is provided with a connecting hole 61 cooperating with the rotatable portion 53, and the rotatable portion 53 is rotatably inserted through the connecting hole 61. The first snap-fit block 6 is fixedly connected to the styling body 1 in a snap-fit manner, thereby assembling and positioning the rotatable portion 53 and the guide member 5 connected thereto as a whole onto the styling body 1.

[0067] Further, as shown in FIGS. 2 and 14, the first snap-fit block 6 is further provided with a first snap-fit hook 62, and the styling body 1 is provided with a second snap-fit hook 15 matching the first snap-fit hook 62. During installation, the rotatable portion 53 is first inserted through the connecting hole 61 of the first snap-fit block 6; the first snap-fit hook 62 of the first snap-fit block 6 is then aligned with the second snap-fit hook 15 on the styling body 1; and finally, a pressure is applied to make the first snap-fit hook 62 and the second snap-fit hook 15 snap into engagement with each other, completing a reliable connection between the first snap-fit block 6 and the styling body 1, thereby firmly assembling the rotatable portion 53 and the guide member 5 connected thereto as a whole in a predetermined position.

[0068] Specifically, as shown in FIGS. 2 and 14, the attachment further includes a second snap-fit block 7. The second snap-fit block 7 includes a mounting portion 71 for connecting with a hair dryer main body. The second snap-fit block 7 is fixedly connected to a side of the styling body 1 away from the first snap-fit block 6 in a snap-fit manner.

[0069] Further, in order to achieve rapid assembly with the styling body 1, the second snap-fit block 7 is further provided with a third snap-fit hook 72, and an outer surface of the styling body 1 is provided with a fourth snap-fit hook 16 matching the third snap-fit hook 72. During installation, by aligning and pressing the third snap-fit hook 72 with the fourth snap-fit hook 16, a reliable snap-fit connection between the second snap-fit block 7 and the styling body 1 can be achieved, thereby completing structural fixation of the attachment to a connection end of the hair dryer main body.

[0070] Working principle of the present disclosure will be described in detail below:

[0071] The main unit is started, and hot/cold air is pumped into the air cavity inside the styling body and is ejected at a high speed through the air outlets of the air-guiding structures along a tangent or at a specific angle to the styling surface. According to Bernoulli's principle and Coandă effect, the high-speed airflow generates a stable negative-pressure adsorption zone near the styling surface; the user brings the hair tips close to the styling surface, and under the action of the negative pressure, the hair tips are gently adsorbed and tightly attached to the styling surface, completing the initial fixation for styling; and the hair roots are kept relatively stationary for rotational winding and drying/setting at the same time while the styling body rotates about its own axis (manually by the user or driven by a motor). Since the hair tips have been adsorbed and fixed, the hair is automatically and uniformly spirally wound around the styling body. The negative-pressure adsorption zone is maintained to ensure that the wound hair remains attached; and the wet hair wound around the styling body is directly blown to accelerate moisture evaporation simultaneously, thereby achieving drying; the attached hair is uniformly heated (or cooled) by hot air (or cold air) for setting; after winding to a desired position, the airflow is maintained for a short period to complete final setting. After the airflow is turned off or switched, the negative pressure disappears, and the formed curls may be easily removed, obtaining a hairstyle with uniform curl and good elasticity.

[0072] The innovation of the present disclosure lies in a novel design that provides air-guiding structures of specific configurations on the styling body, and employs Bernoulli's principle and Coandă effect to form stable negative-pressure adsorption zones near the styling surface through the high-speed outflowing air, thereby replacing conventional mechanical clamping or manual winding, achieving gentle, damage-free adsorption fixation of hair, and integrating negative-pressure adsorption, rotational winding, and hot air (or cold air) blowing/setting functions into a single attachment. When adsorption occurs, the airflow immediately begins to directly dry and heat the hair attached to the surface, thereby realizing an efficient process of “styling starting upon adsorption.” The operation is simple. The user only needs to bring the hair tips close to the styling surface to achieve automatic adsorption, and then complete winding by means of simple rotation (manual or automatic operation), thereby reducing the difficulty of operation.
