[0007] In a preferred embodiment, a thermal insulation rib is provided at the lower end of the thermal insulation pad, and the thermal insulation pad abuts against the comb body through the thermal insulation rib.

[0008] In a preferred embodiment, a buckle is provided at the lower end of the top cover, a slot cooperating with the buckle is provided on the comb body, and a second through hole for the buckle to pass through is also provided on the thermal insulation pad.

[0009] In a preferred embodiment, the edge of the thermal insulation pad is recessed inward to form the second through hole.

[0010] In a preferred embodiment, the top cover comprises a separate top cover body and an operating cover.

[0011] The top end of the top cover body is provided with a concave installation groove, the operation cover is installed in the installation groove, and the operation cover is spaced apart from the groove wall of the installation groove.

[0012] In a preferred embodiment, the top cover body is provided with positioning ribs, and the operating cover is provided with positioning grooves cooperating with the positioning ribs.

[0013] In a preferred embodiment, the operating cover also includes an operating cover body and a cover plate, the operating cover body has a cavity, a first screw hole is provided in the cavity, a second screw hole is provided on the top cover body, and a third screw hole is provided on the comb head body, and the operating cover body, the top cover body and the comb head body are fixedly connected by screws passing through the first screw hole, the second screw hole and the third screw hole, and the cover plate is connected to the operating cover body to hide the screws.

[0014] In a preferred embodiment, the thickness of the heat insulating air layer is not less than 3 mm.

[0015] In a preferred embodiment, the thermal insulation pad is made of aerogel felt or mica board.

[0016] Compared with the prior art, this application has at least the following technical effects:

[0017] 1. The comb head of the present application is provided with supporting ribs at the lower end of the top cover, and the top cover is in contact with the comb head body through the supporting ribs, so that a heat-insulating air layer is formed between the top cover and the comb head body. Since the thermal conductivity of air is low, it is difficult for the heat of the comb head body to be transferred to the top cover through the heat-insulating air layer, which can greatly reduce the temperature of the top cover and improve the safety of the hot air comb. Moreover, since the top cover is in contact with the comb head body through the supporting ribs, the contact area between the top cover and the comb head body is reduced, which reduces solid heat transfer and further reduces the temperature of the top cover.

[0018] 2. A heat insulation pad is provided between the top cover and the comb body. The heat insulation pad is provided with a first through hole for the support rib to pass through. The heat insulation pad has poor thermal conductivity and can reduce the heat transfer of the comb body. Moreover, the double-layer heat insulation effect of the heat insulation pad and the heat insulation air layer can greatly prevent the heat transfer of the comb body, reduce the temperature of the top cover, and improve the safety of the hot air comb.

[0019] 3. Insulating ribs are provided under the thermal insulation pad, and the thermal insulation pad is in contact with the comb body through the thermal insulation ribs. The presence of the thermal insulation ribs reduces the contact area between the thermal insulation pad and the comb body, and reduces the heat conduction between the thermal insulation pad and the comb body. Moreover, the presence of the thermal insulation ribs can form an air layer between the thermal insulation pad and the comb body, further reducing the temperature of the thermal insulation pad, and then reducing the temperature of the top cover.

[0020] 4. A buckle is provided at the lower end of the top cover, and a slot is provided on the comb body. The top cover is connected to the slot of the comb body through the buckle. At the same time, a second through hole allowing the buckle to pass through is formed on the edge of the thermal insulation pad. The top cover can be connected to the comb body through the cooperation of the buckle and the slot. The installation structure is simple and convenient, and it is easy to produce and manufacture.

[0021] 5. The top cover includes a separate top cover body and an operating cover. The top cover body and the operating cover are two separate parts that can slow down heat transfer. The top cover body transitions between the comb body and the operating cover, which can slow down the transfer of heat from the comb body to the operating cover, reduce the temperature of the operating cover, and thus improve the user's safety. A concave mounting groove is provided at the top of the top cover body, and the operating cover is installed in the mounting groove. The operating cover and the groove wall of the mounting groove are spaced apart, which can reduce heat transfer between the operating cover and the top cover body, reduce the temperature of the operating cover, and improve the user's safety.

[0022] 6. The top cover body is provided with positioning ribs, and the operating cover is provided with positioning grooves that cooperate with the positioning ribs. The cooperation between the positioning ribs and the positioning grooves can prevent mistakes. BRIEF DESCRIPTION OF THE DRAWINGS

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. For example Figures 1 to 6 As shown, in order to solve the problem that the top cover 2 of the hot air comb in the prior art overheats and affects the user's operation safety, the present application provides a hot air comb head. Specifically, the comb head includes a comb head body 1 and a top cover 2. The comb head body 1 is provided with an air cavity inside. One end of the comb head body 1 is connected to the handle of the hot air comb and receives the hot air flow from the handle. The other end of the comb head body 1 is connected to the top cover 2. The hot air generated by the hot air component enters the air cavity of the comb head body 1 and is discharged through the air outlet on the surface of the comb head body 1. The lower end of the top cover 2 is provided with a supporting rib 212, and the top cover 2 is abutted against the comb head body 1 through the supporting rib 212 to form a heat insulating air layer between the top cover 2 and the comb head body 1.

[0037] The handle of the hot air comb of the present application is provided with a hot air component capable of generating hot air, and the comb head and the handle may be detachably connected or fixedly and non-detachably connected.

[0038] like Figure 2 , 3As shown, the hot air comb of the present application is provided with a support rib 212 at the lower end of the top cover 2, and the top cover 2 is in contact with the comb body 1 through the support rib 212, so that a heat insulating air layer is formed between the top cover 2 and the comb body 1. Since the thermal conductivity of air is low, it is difficult for the heat of the comb body 1 to be transferred to the top cover 2 through the heat insulating air layer, which can greatly reduce the temperature of the top cover 2 and improve the safety of the hot air comb. Moreover, since the top cover 2 is in contact with the comb body 1 through the support rib 212, the contact area between the top cover 2 and the comb body 1 is reduced, which reduces solid heat transfer and further reduces the temperature of the top cover 2.

[0039] Specifically, in the present application, a bristle body 12 is provided on one side of the surface of the comb body 1, and aluminum teeth and an aluminum tooth sheath 11 covering the outside of the aluminum teeth are provided on the other side. The bristle body 12 is provided with comb teeth and an air outlet connected to the wind cavity. The airflow generated by the hot air component in the handle is discharged through the air outlet in the bristle body 12, so that the hair can be combed while drying. Moreover, the aluminum teeth have a higher temperature, so the hair can be straightened, so that the hot air comb has a better hair combing effect.

[0040] In this application, if Figure 3 As shown, the aluminum tooth sheath 11 includes a top plate 111, a bottom plate 113 and a sheath plate 112 connected between the top plate 111 and the bottom plate 113, the top plate 111 is located at the top end of the comb body 1, the bottom plate 113 is located at the bottom end of the comb body 1, and the sheath plate 112 is covered on the outside of the aluminum teeth. The top cover 2 is fixed to the top plate 111 of the aluminum tooth sheath 11. Preferably, the top cover 2 has the same shape as the top plate 111 of the aluminum tooth sheath 11, and the top cover 2 can prevent the user from contacting the aluminum tooth sheath 11 and getting burned.

[0041] In the present application, the thickness of the heat insulating air layer is preferably not less than 3 mm. A thicker heat insulating air layer can greatly reduce the heat transfer between the comb body 1 and the top cover 2, thereby improving the safety of the hot air comb. It is understandable that from the perspective of reducing the volume of the hot air comb, the thickness of the heat insulating air layer should not be too large. An overly large heat insulating air layer will result in a low space utilization rate for the entire hot air comb, which is not conducive to miniaturization design.

[0042] like Figure 1 , 2 4, in order to further reduce the temperature of the top cover 2 and improve the safety of the hot air comb, in the present application, a heat insulation pad 3 is further provided between the top cover 2 and the comb body 1, and a first through hole 32 is provided on the heat insulation pad 3 for the support rib 212 to pass through. The heat insulation pad 3 is clamped between the top cover 2 and the comb body 1. When the top cover 2 is installed on the comb body 1, the support rib 212 at the lower end of the top cover 2 passes through the first through hole 32 on the heat insulation pad 3 and is supported on the comb body 1. Specifically, the heat insulation pad 3 is provided between the top plate 111 of the aluminum tooth sheath 11 and the top cover 2.

[0043] Since the material of the heat insulation pad 3 is generally a material with a low thermal conductivity, such as aerogel felt or mica board, it can greatly reduce the heat transfer from the comb body 1 to the top cover 2, thereby reducing the temperature of the top cover 2. Moreover, through the dual heat insulation effect of the heat insulation air layer and the heat insulation pad 3, the temperature of the top cover 2 can be greatly reduced, thereby improving the safety of the hot air comb.

[0044] It is understandable that, in the present application, a heat-insulating air layer can be formed between the top cover 2 and the heat-insulating pad 3, and a heat-insulating air layer can also be formed between the heat-insulating pad 3 and the comb body 1. In a preferred embodiment of the present application, a raised heat-insulating rib 33 is provided at the lower end of the heat-insulating pad 3, and the heat-insulating pad 3 abuts against the comb body 1 through the heat-insulating rib 33, and a heat-insulating air layer is formed between the heat-insulating pad 3 and the comb body 1. The temperature of the top cover 2 is greatly reduced through the double barrier of the heat-insulating pad 3 and the heat-insulating air layer.

[0045] like Figure 1-4 As shown, in order to realize the easy installation of the top cover 2, the comb body 1, and the heat insulation pad 3, in the present application, a buckle 211 is provided at the lower end of the top cover 2, a groove 1111 cooperating with the buckle 211 is provided on the comb body 1, and a second through hole 31 is provided on the heat insulation pad 3 for the buckle 211 to pass through. When the top cover 2 is installed on the comb body 1, the installation of the top cover 2 and the comb body 1 is realized by the cooperation of the buckle 211 and the groove 1111. Since the heat insulation pad 3 is clamped between the top cover 2 and the comb body 1, the heat insulation pad 3 can be reliably fixed when the top cover 2 is connected to the comb body 1. In a preferred embodiment of the present application, the second through hole 31 is formed by the inward depression of the edge of the heat insulation pad 3.

[0046] like Figure 1 , 3 , 5 and 6, in the present application, in order to further reduce the temperature of the top cover 2, the top cover 2 is made into parts, that is, the top cover 2 is composed of a top cover body 21 and an operating cover 22, the top cover body 21 is fixed to the comb body 1, the heat insulation pad 3 is clamped between the top cover body 21 and the comb body 1, and the operating cover 22 is installed at the upper end of the top cover body 21. The operating cover 22 and the top cover body 21 are divided into parts rather than an integral arrangement, which can effectively block the heat of the comb body 1 from being transferred to the operating cover 22, further reducing the temperature of the operating cover 22 and improving the user's safety.

[0047] In the present application, a concave mounting groove 214 is provided at the top of the top cover body 21, and the operating cover 22 is installed in the mounting groove 214. The operating cover 22 and the groove wall of the mounting groove 214 are spaced apart, which can effectively prevent the heat from being transferred from the top cover body 21 to the operating cover 22. It can be understood that in the present application, the support rib 212 is formed at the lower end of the top cover body 21.

[0048] In addition, in the present application, a positioning rib 215 is provided on the top cover body 21, and the operating cover 22 is provided because the positioning rib 215 cooperates with the positioning groove 221. Through the cooperation of the positioning rib 215 and the positioning groove 221, the anti-misalignment limiting of the operating cover 22 and the top cover body 21 can be achieved.

[0049] Specifically, the operating cover 22 includes an operating cover body 222 and a cover plate 223. The operating cover body 222 has a cavity, and a first screw hole 224 is arranged in the cavity. The top cover body 21 is provided with a second screw hole 213, and the top plate 111 of the aluminum tooth sheath 11 is provided with a third screw hole 1112. The top cover body 21, the operating cover 22, and the aluminum tooth sheath 11 are fixed by screws passing through the first screw hole 224, the second screw hole 213, and the third screw hole 1112 in sequence, so as to realize the fixation of the operating cover body 22, the top cover body 21 and the comb head body 1, and then the cavity of the operating cover body 222 is blocked by the cover plate 223.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention and will not be listed one by one here.
