[0033] The following will be combined with the attached Figure 1-6 The hot air comb of the present application is introduced in detail.

[0034] The hot air comb of the present application comprises a combing head 2, a handle 3, a power cord 4, and a top cover assembly 1. The combing head 2 is mounted on the upper end of the handle 3, the top cover assembly 1 is arranged on the upper end of the combing head 2, and the lower end of the handle 3 is connected to the power cord 4. When a user uses the hot air comb, the power cord 4 is plugged into an external power source, the handle 3 is held, and the comb teeth on the combing head 2 are used to comb the hair, so as to achieve the effect of drying the hair and cutting the hair at the same time.

[0035] An air duct is arranged inside the comb head 2, a hair-planting body is arranged on the surface of the comb head 2, comb teeth and an air outlet connected to the comb teeth are arranged on the hair-planting body, the handle 3 includes an outer shell 32 and an inner shell 31 arranged inside the outer shell 32, the inner shell 31 is a hollow cylinder, a driving motor 6, a circuit board and a first heating element 10 are arranged inside the inner shell 31, the inner shell 31 includes a first half shell 311 and a second half shell 314 split along the axial direction of the inner shell 31, the first half shell 311 and the second half shell 314 are fixedly connected, the first half shell 311, or the second half shell 314, or the first half shell 311 and the second half shell 314 are transparent at the corresponding position of the circuit board 13. With such a configuration, the movement of the internal wires can be observed through the inner shell 31, which is convenient for observing whether the internal components are reliably installed during the production process, thereby improving the reliability of the entire machine. Splitting the inner shell 31 into the first half shell 311 and the second half shell 314 can facilitate the installation of electronic components in the inner shell 31.

[0036] In the present application, the second half shell 314 includes an upper half shell 312 and a lower half shell 313. The upper half shell 312 and the first half shell 311 are enclosed to form an upper cavity. The drive motor 6 is installed in the upper cavity. The lower half shell 313 and the first half shell 311 are enclosed to form a lower cavity. The circuit board 13 is installed in the lower cavity. The lower half shell 313 is a transparent part. By setting the lower half shell 313 as a transparent part, the line routing in the lower cavity can be fully observed through the lower half shell 313, thereby improving the reliability of the assembly process. Preferably, the length of the lower half shell 313 is greater than the length of the circuit board 13. In this way, the lower half shell 313 can be fully utilized to observe the installation of components in the lower cavity. Since the lower half shell 313 is a transparent part, the material of the transparent part is generally polyethylene, polyvinyl chloride, polypropylene, polycarbonate, etc., and the heat resistance of the above materials is generally poor. In order to prevent the inner shell 31 from overheating and melting, the present application splits the second half shell 314 into an upper half shell 312 and a lower half shell 313, and only sets the lower half shell 313 as a transparent part, which can reduce the area of ​​the transparent part as much as possible and improve the heat resistance of the inner shell 31.

[0037] Specifically, in the present application, the lower end of the lower half shell 313 is clamped with the first half shell 311, the upper end of the lower half shell 313 is fastened with the first half shell 311 by the second screw 11, the lower end of the upper half shell 312 is clamped with the first half shell 311, and the upper end of the upper half shell 312 is fastened with the first half shell 311 by the third screw 12. The upper half shell 312, the lower half shell 313 and the first half shell 311 are fastened by the second screw 11 and the third screw 12, so that the inner shell 31 can be reliably installed.

The partition 3111 is provided with air holes 15 to allow air flow to pass through. The partition 3111 can separate the upper cavity and the lower cavity, reduce the heat transfer from the upper cavity to the lower cavity, and avoid overheating damage to the circuit board in the lower cavity. Specifically, the drive motor 6 is installed above the partition 3111, and the first heating element 10 is installed in the upper cavity above the drive motor 6. When the drive motor 6 is working, the airflow generated is blown toward the first heating element 10, and the hot air is formed after being heated by the first heating element 10, and then flows to the air duct in the combing head 2. In the present application, the first heating element 10 includes a heating frame and a heating wire wound on the heating frame. In other implementations, the first heating element 10 can also adopt other forms of heating devices.

[0039] In the present application, a wire hole 3122 is provided on the upper half shell 312, and a wire management groove 3123 is provided on the outer side of the upper half shell 312. The wire hole 3122 is located above the wire management groove 3123. The wires electrically connected between the circuit board 13 and the drive motor 6 are fixed through the wire management groove 3123, and then the wire hole 3122 enters the inner shell 31 and is connected to the drive motor 6. The wires are located in the space between the inner shell 31 and the outer shell 32 to reduce the wind resistance in the air duct. A sealing member for sealing the wire hole 3122 is also provided to prevent the airflow of the inner shell 31 from overflowing from the wire hole 3122, resulting in loss of air volume and air pressure, and heating of the handle.

The outer shell 32 is provided with a groove 16 for installing the switch cover plate 9. The circuit board 91 is arranged between the outer shell 32 and the inner shell 31. A through hole 17 is provided in the switch cover plate 9 and the groove 16. The button 92 is assembled on the switch cover plate 9 and extends into the through hole 17 to cooperate with the circuit board 91. The circuit board 91 is electrically connected to the circuit board 13. The hot air comb can be turned on and off, and the air temperature and wind speed of the hot air comb can be adjusted.

[0041] In addition, a filter screen 7 and an air inlet screen cover 8 sleeved on the outside of the filter screen 7 are also provided at the end of the handle 3 .

[0042] The combing head 2 of the present application is provided with a slot 14 at the lower end, and a clip rib 3121 is provided at the upper end of the upper half shell 312. When the handle 3 is mounted on the combing head 2, the clip rib 3121 is inserted into the slot 14, and the first screw 5 is sequentially passed through the slot and the screw holes on the clip rib 3121 to achieve the installation of the combing head 2 of the handle 3. Specifically, the inner shell 31 and the combing head 2 can be installed first, and then the outer shell 32 can be sleeved on the outer side of the inner shell 31. The outer shell 32 can be assembled later to cover the first screw 5, thereby ensuring the aesthetic appearance of the hot air comb.
