[0027] The present invention will be further described below in conjunction with the accompanying drawings:

[0028] like Figures 1 to 7 The wind reversing device of a hair straightening comb shown in the figure comprises a comb body 1, the comb body 1 is provided with an air inlet 2 and an air outlet 3, the air inlet 2 is provided with an air inlet 21, the comb body 1 is provided with a left air duct 41 and a right air duct 42, the air outlet 3 is provided with a first comb tooth 51, a left air outlet 411 communicating with the left air duct 41, and a right air outlet 421 communicating with the right air duct 42, the comb body 1 is further provided with an air distribution cavity 43 communicating with the air inlet 21, the left air duct 41 and the right air duct 42, the air distribution cavity 43 is provided with a movable part 6 that can block the left air duct 41 or the right air duct 42 by gravity when the comb body 1 is tilted. Among them, the air inlet 2 is provided with a plug connector 20 that can be plugged with a handle, and the plug connector 20 is provided with a clamping block 200 that can be buckled with the handle.

[0029] In this case, by setting a movable part 6 in the air distribution cavity 43, the left air duct 41 or the right air duct 42 can be automatically blocked by gravity according to the tilt angle of the straight hair comb, so that when the user combs the hair, there is no need to manually adjust the airflow direction, and the airflow path will be automatically optimized according to the actual position and movement of the comb; because the air outlet direction always matches the user's combing action, the extra pulling and pressure on the hair caused by the reverse airflow is avoided, and the risk of hair breakage or split ends is reduced. At the same time, more uniform and directional airflow distribution can reduce overheating areas, prevent hair damage caused by local excessive temperature, and provide a gentler hair care experience. Using gravity to change the direction of air outlet not only simplifies the internal mechanical structure, but also reduces the manufacturing cost and maintenance difficulty. Users can enjoy the convenience brought by intelligent airflow control without learning complicated operating steps, which improves the user experience.

[0030] In one embodiment, the movable member 6 includes a swing wheel 61 , a mounting frame 62 is provided in the air inlet 21 , a rotating shaft 63 arranged along the air inlet direction is connected to the mounting frame 62 , and one side of the swing wheel 61 is rotatably connected to the rotating shaft 63 .

[0031] The swing wheel 61 is connected to the mounting frame 62 via a rotating shaft 63, and can quickly respond to changes in the tilt angle of the straightening comb, thereby ensuring the timeliness and accuracy of the air outlet reversal, so that the airflow always cooperates with the user's combing action. The design of the rotating shaft 63 provides a stable rotation support point, ensuring that the swing wheel 61 moves smoothly and without jamming under the action of gravity, thereby ensuring the stability of airflow control. The rotating connection reduces the friction surface and reduces the wear rate between components. Compared with the traditional sliding or rolling contact method, this method can significantly extend the service life of the movable part 6. Among them, the mounting frame 62 can be connected to the wall of the air inlet 21 by interference fit or other connection methods such as snaps.

[0032] In one embodiment, the movable member 6 includes a ball 64, and the air inlet end 2 is further provided with a limiting ring 65 for limiting the ball 64 from rolling out of the air distribution cavity 43.

[0035] The left hollow groove 711 and the right hollow groove 712 can effectively break up the concentrated airflow from the air duct, so that it is more evenly distributed on the hair. This helps to avoid damage to the hair caused by local overheating or excessive airflow concentration, while improving the uniformity of drying and styling. The broken airflow can contact the hair more gently, reducing the risk of pulling and breaking caused by direct blowing, and protecting the health of the hair. In addition, the evenly distributed airflow helps to maintain the moisture balance of the hair, reduce frizziness, and enhance the hair care effect.

[0036] In one embodiment, the comb body 1 includes a comb seat 11, a shell 12 sleeved on the outside of the comb seat 11, and a comb tooth seat 13 connected to the shell 12.
