[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Please refer to the following: Figures 1 to 6 The hot air comb 100 provided in the embodiments of this application will now be described. The hot air comb 100 includes a handle 10 and a comb head 20.

[0037] The comb head 20 has a hollow groove 21 that runs through its upper and lower surfaces at its center. The comb head 20 is equipped with a light-emitting structure 40. The light-emitting structure 40 has a light-emitting protrusion, a light source assembly 42 that provides a light source to the light-emitting protrusion 411, and a light-shielding part 431. The light-emitting protrusion 411 is exposed on the side of the hollow groove 21. The light-shielding part 431 covers the bottom of the light-emitting protrusion 411 and makes the light source of the light-emitting protrusion 411 shine towards the end of the comb tooth assembly 30.

[0038] In some embodiments, the comb head 20 is disposed at one end of the handle 10, and the upper surface of the comb head 20 is provided with a comb tooth assembly 30 protruding upward. A hollow groove 21 penetrating the upper and lower surfaces is provided at the center of the comb head 20. The comb head 20 has a mounting chamber 22, which is connected to the hollow groove 21 through a clearance notch 23. The mounting chamber 22 is provided with a light-emitting structure 40, which includes a light guide ring 41, a light source assembly 42 that emits light toward the light guide ring 41, and a light shielding ring 43. The light guide ring 41 can extend through the clearance notch 23 to cover the hollow groove 21. The light-emitting protrusion is disposed on the light guide ring and is provided with a light source by the light source assembly. The light source is refracted by the light guide ring and finally emitted from the light-emitting protrusion 411 toward the hollow groove 21 and the comb tooth assembly 30. The light guide ring 41 and the light shield ring 43 are stacked one on top of the other. The light shield ring 43 and the light guide ring 41 extend together through the avoidance notch 23 to the hollow groove 21. The light shielding part 431 is located on the light shield ring 43 and below the light-emitting protrusion 411, thereby blocking the light source from shining downward from the hollow groove 21.

[0039] Specifically, through the hollow groove 21, and with a clearance notch 23 extending through the side of the hollow groove 21 in the mounting chamber 22; the light-emitting protrusion 411 of the light guide ring 41 and the light-shielding part 431 of the light shield ring 43 extend into the hollow groove 21 through the clearance notch 23, so that the light source assembly 42 can be emitted from the light-emitting protrusion 411 into the hollow groove 21 and the comb tooth assembly 30 end, and the light source is blocked from being emitted to the lower surface of the comb head 20 by the light shield 431; firstly, when the user uses the hot air comb 100 to dry or style hair, the problem of strong light shining directly into the eyes can be avoided, thereby improving the safety performance of the hot air comb 100; secondly, the light-emitting protrusion 411 can be extended through the clearance notch 23 into the hollow groove 21. 11. The light source is controlled to shine only onto the hollow groove 21 and the comb tooth assembly 30. The light source can directly and concentratedly illuminate the comb teeth and the hair interspersed therein. Especially for heated combs, it can more effectively apply heat and light source to the target area (such as the hair roots or ends), thereby improving the actual effect of functions such as heated styling, local drying, and hair care. Thirdly, the light source can be diffused through the light guide ring 41 structure, which can solve the problem of direct illumination of LED lights in traditional technology, making the emitted light source more uniform. Moreover, the light source shines only onto the hollow groove 21 and the comb tooth assembly 30, which can improve the overall aesthetics of the hair comb and thus improve the user's visual experience.

[0040] In some embodiments, the hollow groove 21 is provided as a long strip through hole structure or a ring track circular structure; the light guide ring 41 has a first clearance opening 412 at the center position that matches the shape of the hollow groove 21, and the first clearance opening 412 penetrates the upper and lower surfaces of the light guide ring 41; the light shield ring 43 has a second clearance opening 432 at the center position that matches the shape of the hollow groove 21, and the second clearance opening 432 penetrates the upper and lower surfaces of the light shield ring 43.

[0041] Preferably, the first width is defined in the left-right direction of the hollow groove 21, and the second width is defined in the left-right direction of the first clearance opening 412, with the first width being greater than the second width.

[0042] Specifically, the light-emitting protrusion 411 is located at the edge of the hollow groove 21. The light-emitting protrusion 411 has a first light-emitting surface 4111 that emits light upward and a second light-emitting surface 4112 that emits light towards the center of the hollow groove 21. The light-shielding part 431 covers the lower surface of the light-emitting protrusion 411. The light guide ring 41 also has a light-incident protrusion 413. Both the light-incident protrusion 413 and the light-emitting protrusion 411 are located on the upper surface of the light guide ring 41. The light source assembly 42 includes a PCB board 421 and an LED bead 422 integrated on the lower surface of the PCB board 421. The PCB board 421 is located in the mounting chamber 22 and above the light guide ring 41. The LED bead 422 is located above the light-incident protrusion 413.

[0043] This structure enables the LED beads 422 located in the mounting cavity to emit light. This light source is introduced through the light-incident protrusion 413 and emitted from the light-emitting protrusion 411, achieving a uniform light emission effect and reducing the possibility of instantaneous glare and visual interference caused by direct light. Simultaneously, the clever placement of the light-emitting protrusion 411 within the hollow groove 21, along with the light-shielding part 431 covering its bottom, ensures that the light-emitting protrusion 411 emits light only towards the hollow groove 21 and the comb assembly 30. This improves the precise guidance of the light source's propagation path, reducing light leakage or light pollution, thereby significantly enhancing the user experience and safety of the hot air comb 100.

[0044] In other embodiments, the comb head 20 includes an upper comb shell 201 and a lower comb shell 202; the comb tooth assembly 30 includes a comb tooth fixing frame 31 disposed on the upper comb shell 201 or the lower comb shell 202, a first comb tooth seat 32 disposed on the comb tooth fixing frame 31, and a second comb tooth seat 33 disposed between the comb tooth fixing frame 31 and the first comb tooth seat 32. The first comb tooth seat 32 has a plurality of first teeth 321 protruding upward, and the second comb tooth seat 33 has a plurality of second teeth 331 protruding upward; the comb tooth fixing frame 31 and the lower comb shell 202 enclose the mounting chamber 22. The first comb tooth and the second comb tooth extend from bottom to top, and the light source emitted by the light-emitting protrusion 411 can be emitted in the extending direction of the first comb tooth and the second comb tooth.

[0045] It is understood that the first comb tooth section and the second comb tooth section can be any one of comb needles or comb teeth or a combination thereof; heaters are provided in the first comb tooth seat 32 and the second comb tooth seat 33, which can heat each of the first comb tooth section and the second comb tooth section to assist the user in combing hair.

[0046] Preferably, the handle 10 includes an upper handle shell integrally formed on one end of the upper comb shell 201 and a lower handle shell integrally formed on the lower comb shell 202. The upper comb shell 201 and the lower comb shell 202, as well as the upper handle shell and the lower handle shell, can be installed by any of the following processes: snap-fit ​​installation, screw fastening installation, adhesive fixing or welding fixing.

[0047] Specifically, the first comb tooth holder 32 has a first sidewall 322, and the lower comb shell 202 has a second sidewall 2021. The first sidewall 322 and the second sidewall 2021 enclose a hollow groove 21. A clearance notch 23 is provided between the bottom of the first sidewall 322 and the top of the second sidewall 2021. The comb tooth fixing frame 31 and the lower comb shell 202 enclose an installation chamber 22. A light-emitting protrusion 411 is provided at the edge of the first clearance opening 412. The light-emitting protrusion 411 and the light-receiving protrusion 413 are spaced apart and enclose a first installation notch 414 with the opening facing upward. The comb tooth fixing frame 31 has a third sidewall 311. The first sidewall 322 and the third sidewall 311 are stacked inside and outside. The first sidewall 322 and the third sidewall 311 extend downward and are inserted into the first installation notch 414.

[0048] Furthermore, the light-shielding ring 43 is fastened to the lower surface of the light guide ring 41. The upper surface of the light-shielding ring 43 is provided with a second mounting notch 433, and the lower surface of the light guide ring 41 is provided with a fourth sidewall 415 for inserting into the second mounting notch 433. The lower surface of the light-shielding ring 43 is provided with a third mounting notch 434, and the inner and outer distances between the second mounting notch 433 and the third mounting notch 434 are set. The second sidewall 2021 is inserted into the third mounting notch 434. This structure can improve the reliability and convenience of installation between the light-emitting structure 40 and the comb head 20.

[0049] It should be noted that the entire light-shielding ring can be made of an opaque material, or only the light-shielding part can be made of an opaque material; of course, the light-shielding effect can also be achieved by coating or screen-printing paint on the light-shielding ring and / or the light-shielding part to form a light-shielding layer.
