Description

Technical Field

[0001] This utility model relates to the field of beauty and hairdressing tools, and in particular to a hair care comb, such as a straightening comb. Background Technology

[0002] Hair straighteners are widely used in the hairdressing industry to straighten hair. They mainly consist of a shell, bristles, and a handle. Some also include heating elements, highly thermally conductive metal bristles (such as heated bristles), and heat insulation devices. Hair is straightened more easily after passing through the heated metal bristles. Traditional hair straighteners can only comb hair; even with heating elements, they only help heat the hair and are not very effective at straightening it. Therefore, some have invented hair straighteners with a blower function. For example, Chinese invention patent application CN119523239A discloses a hair straightener with an airflow diversion device and a hair straightener. This device, by incorporating a movable component within the air distribution chamber, automatically blocks the left or right airflow channel based on the comb's tilt angle and gravity. This allows users to automatically optimize the airflow path based on the comb's position and movement without manually adjusting the airflow direction. However, the airflow of this solution can only blow out along the direction of the comb teeth, and cannot blow out in the direction of combing the hair. Therefore, its function is only to avoid the extra pulling and pressure on the hair caused by the reverse airflow, and reduce the risk of hair breakage or split ends, but it cannot help straighten the hair. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a hair care comb with a more reasonable and simpler structure that allows air to blow out in the direction of hair combing, thus helping to straighten hair and improving the straightening effect and user experience.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A hair care comb, comprising a shell, a comb tooth assembly, and an air duct. The comb tooth assembly includes fixed comb teeth and movable comb teeth. The fixed comb tooth assembly includes fixed comb teeth and a fixed comb tooth seat, with the fixed comb tooth seat fixedly mounted on the shell. An air outlet channel is provided in the fixed comb tooth seat. The movable comb tooth assembly includes movable comb teeth and a movable comb tooth seat, with the movable comb tooth seat movably mounted at the air outlet channel of the fixed comb tooth seat to form a structure that can swing left and right. The air duct is disposed in the shell, and the movable comb tooth assembly is connected to the air duct, allowing air to pass through the gaps created on its left and right sides when the movable comb tooth assembly swings. An airflow channel is formed, which is connected to the air duct. Guide edges extend outward from both sides of the movable comb tooth seat to form flow guides, and stop edges extend towards the middle from both sides of the air outlet channel on the fixed comb tooth seat to form stop edges. The width of the entire movable comb tooth seat is greater than the width of the air outlet channel between the two stop edges, so that when the movable comb tooth swings to one side, the flow guide edge on that side rotates to press down on the stop edge on the same side to close the airflow channel on that side and expose the airflow channel on the other side. The side of the flow guide edge opposite to the stop edge is set as an arc-shaped concave surface, so that the outer end of the flow guide edge bends towards the stop edge. The arc-shaped concave surface forms a structure that guides the air outlet in the same direction as the hair combing.

[0005] Furthermore, pins are provided at both ends of the movable comb tooth seat, and the pins are embedded in the fixed comb tooth seats at both ends of the air outlet channel to form a structure that can rotate left and right.

[0006] Furthermore, at least one retaining ring is provided on each shaft pin, and a rotating groove is provided in the movable comb tooth seat at the position corresponding to the retaining ring, and the retaining ring is engaged in the rotating groove.

[0007] Furthermore, it also includes heated comb teeth and heat-insulating comb teeth. The heated comb teeth are connected to a heating element, and the heat-insulating comb teeth include heat-insulating comb teeth and heat-insulating comb tooth seats. The heat-insulating comb teeth are fitted over the outside of the heated comb teeth, and each heated comb tooth corresponds to one heat-insulating comb tooth.

[0008] Furthermore, the heat-insulating comb tooth seat cover locks the pin of the movable comb tooth seat on the fixed comb tooth seat, allowing the pin to rotate between the fixed comb tooth seat and the heat-insulating comb tooth seat.

[0009] Furthermore, the movable comb teeth are located in the middle area of ​​the fixed comb teeth, and the heated comb teeth are located on one or both sides next to the movable comb teeth.

[0010] More preferably, the heated comb teeth are arranged in at least two rows on each side of the movable comb teeth, and the heated comb teeth in adjacent rows are staggered.

[0011] Preferably, the bottom of the air duct has a structure that gradually rises forward, so that the distance between the movable comb seat and the bottom of the air duct gradually decreases forward.

[0012] Furthermore, the housing includes a front shell and a bottom cover, which are assembled and connected to fix the fixed comb teeth, heat-insulating comb teeth, and air duct. A connector is installed at the tail end of the front shell and the bottom cover, and a conductive pin is installed in the connector. An adapter plate is provided between the front end of the connector and the tail end of the front shell and the bottom cover, and the heating element and the conductive pin are electrically connected through the adapter plate. A connecting groove is provided on the surface of the connector, and a detachable connection structure is formed with the main unit with the fan through the connecting groove.

[0013] This invention features stop edges on both sides of the air outlet channel of the fixed comb tooth base, and guide edges extending outward from both sides of the movable comb tooth plate to cover the stop edges. When the movable comb tooth oscillates left and right during hair combing, the guide edge on one side presses down on the stop edge on the corresponding side to close the airflow channel on that side, while simultaneously opening the airflow channel on the other side. The airflow follows the extension direction of the guide edge and blows outward through the airflow channel, making the direction of airflow essentially the same as the direction of hair combing. This achieves the goal of straightening hair while drying it, resulting in a better straightening effect and improved user experience. Attached Figure Description

Detailed Implementation

[0023] In this embodiment, refer to Figures 1-8 The hair care comb, which can be used with a main unit 8 equipped with a fan, includes a housing consisting of a face shell 11 and a back cover 12, a comb tooth assembly, and an air duct 6. The comb tooth assembly includes fixed comb teeth 2 and movable comb teeth 3. The fixed comb teeth 2 includes fixed comb teeth 21 and fixed comb tooth seats 22. The fixed comb tooth seats 22 are fixedly installed on the face shell 11, and an air outlet channel 23 is provided in the fixed comb tooth seats 22. The movable comb teeth 3 includes movable comb teeth 31 and movable comb tooth seats 32. The movable comb tooth seats 32 are movably installed at the air outlet channel 23 of the fixed comb tooth seats 22 to form a structure that can swing left and right, with a swing angle of 3-45 degrees. The air duct 6 is installed in the bottom cover 12 and pressed down by the face shell 11 (the air duct 6 can also be set as an integral structure with the bottom cover 12). The movable comb teeth 3 is connected to the air duct 6, and when the movable comb teeth 3 swings, air is generated on its left and right sides. The gap forms an airflow channel 9, which is connected to the air duct 6. The two sides of the movable comb tooth seat 32 extend outward to form a guide edge 35. The two sides of the fixed comb tooth seat 22 extend towards the middle along the air outlet channel 23 to form a stop edge 24. The width of the entire movable comb tooth seat 32 is greater than the width of the air outlet channel 23 between the two stop edges 24. When the movable comb tooth 3 swings to one side, the guide edge 35 on that side rotates to press the stop edge 24 on the same side to close the airflow channel 9 on that side and expose the airflow channel 9 on the other side. The side of the guide edge 35 opposite to the stop edge 24 is set as an arc-shaped concave surface 36, so that the end of the guide edge 35 is slightly raised towards the stop edge 24. In this way, the air outlet is guided in the same direction as the hair combing through the arc-shaped concave surface 36, which can significantly help straighten the hair 10 and make the hair smoother. For example, when combing hair to the right 10, the movable comb teeth 31 rotate to the left due to the force to the left. At this time, the airflow channel 9 on the left side is closed, and the airflow channel 9 on the right side is fully opened, so that the air blows out to the right along the arc-shaped concave surface 36 of the right guide 35 in the direction of combing hair. Figure 5 As shown. When combing your hair to the left for 10 seconds, the direction of the airflow will change to the left, following the direction of combing the hair, as shown. Figure 6As shown.

[0024] A pivot pin 33 is provided at both the front and rear ends of the movable comb tooth seat 32. The pivot pin 33 is embedded in the fixed comb tooth seat 22 at both ends of the air outlet channel 23 to form a structure that can rotate left and right, that is, rotate around the pivot pin 33.

[0025] A retaining ring 34 is provided on each shaft pin 33. A rotating groove 25 is provided in the movable comb tooth seat 32 at the position corresponding to the retaining ring 34. The retaining ring 34 is engaged in the rotating groove 25, which can play a role in preventing it from falling off.

[0026] It also includes heated comb teeth 4 and heat-insulating comb teeth 5. The heated comb teeth 4 are connected to heating elements 41 (PTC and / or NTC heating elements). The heat-insulating comb teeth 5 includes heat-insulating comb teeth 51 and heat-insulating comb tooth seats 52, which can be made of silicone. The heat-insulating comb teeth 5 are fitted over the outside of the heated comb teeth 4, and each heated comb tooth 51 corresponds to one heat-insulating comb tooth 4. The heated comb teeth 4 heat the hair to soften it and further straighten and smooth it.

[0027] The heat-insulating comb tooth seat 52 covers the fixed comb tooth seat 22 and locks the shaft pin 33 of the movable comb tooth seat 32, so that the shaft pin 33 can rotate between the fixed comb tooth seat 22 and the heat-insulating comb tooth seat 52.

[0028] The movable comb teeth 3 are located in the middle area of ​​the fixed comb teeth 2, and the heated comb teeth 4 are located on both sides of the movable comb teeth 3 (only one side is also acceptable). There are two rows of heated comb teeth 4 on each side of the movable comb teeth 3, and the adjacent rows of heated comb teeth 4 are staggered to provide greater friction to the hair and further improve the straightening effect.

[0029] The bottom of the air duct 6 is a structure that gradually rises forward, so that the distance between the movable comb seat 32 and the bottom of the air duct 6 gradually decreases forward, which can create a squeezing effect on the air and increase the pressure of the air blown out.

[0030] The front cover 11 and the bottom cover 12 are assembled and connected to fix the fixed comb teeth 2, the heat-insulating comb teeth 5 and the air duct 6. A connector 7 is installed at the tail end of the front cover 11 and the bottom cover 12, and a conductive pin 72 is provided in the connector 7. An adapter plate 73 is provided between the front end of the connector 7 and the tail end of the front cover 11 and the bottom cover 12, and the heating element 41 and the conductive pin 72 are electrically connected through the adapter plate 73. A connecting groove 71 and an anti-detachment groove are provided on the surface of the connector 7. A connecting buckle and an anti-detachment buckle can be provided on the main unit 8 to match the connecting groove 71 and the anti-detachment groove respectively. The connecting buckle and the connecting groove 71, the anti-detachment buckle and the anti-detachment groove are interlocked to form a detachable connection structure with the main unit 8. This allows for flexible replacement of main units with different functions. For example, a heating element 81 can be provided in the main unit 8 to blow out hot air.

[0031] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
