[0001] This utility model belongs to the field of hair styling tool technology, specifically a wireless curling comb. Background Technology

[0002] A heated curling brush is a hairdressing tool used for drying wet hair and creating simple curls. It consists of a heating element, a highly conductive metal comb head, and a heat-resistant and well-insulated handle. Heated curling brushes are divided into two main categories: corded and cordless. Corded curling brushes are powered by AC mains electricity, while cordless curling brushes are powered by a built-in rechargeable battery. Therefore, cordless curling brushes require their heating element to have excellent heat transfer efficiency and low heat storage to achieve fast heat transfer, low energy consumption, and to maximize battery life per charge.

[0003] In actual use, the fit between the heating element and the inner wall of the curling barrel of existing wireless curling combs is easily affected by the assembly structure, and the uniformity of the fit of the heating element in some products needs further optimization. Summary of the Invention

[0004] To address the problems mentioned in the background art, this utility model provides a wireless curling comb to solve the problems of poor uniformity of heating film adhesion and poor fixation stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wireless curling comb, characterized in that it comprises: a curling barrel shell, a heating element, and a connecting base. The curling barrel shell has a hollow cylindrical structure, and its outer wall is provided with comb teeth. The connecting base is connected to the bottom end of the curling barrel shell. The heating element is assembled in the inner wall area of ​​the curling barrel shell, and the heating element includes an elastic clamping member and a heating film. The heating film is wrapped around the elastic clamping member, inserted into the inner wall of the curling barrel shell, and connected to the connecting base.

[0006] Optionally, the elastic clamping member is an open-type hollow cylindrical shell structure, and its outer diameter in its natural state is larger than the inner wall diameter of the hair curler shell.

[0007] Optionally, the elastic clamping member is made of elastic modified engineering plastic, specifically thermoplastic elastomer modified polypropylene copolymer.

[0008] Optionally, the connecting seat has an annular groove and a circular hole groove communicating with the annular groove inside. The inner wall of the elastic clamping member has clamping holes on opposite sides, and its lower edge is embedded in the annular groove. The clamping hole is engaged in the circular hole groove.

[0009] Optionally, the connecting seat has an annular groove and a circular hole groove communicating with the annular groove inside. The inner wall of the elastic clamping member has clamping holes on opposite sides, and its lower edge is embedded in the annular groove. The clamping hole is engaged in the circular hole groove.

[0010] Optionally, the heating film is adapted to the inner wall contour of the elastic clamp and the clamping hole, and is covered or wrapped around and fixed to the inner wall of the elastic clamp and the two clamping holes.

[0011] Optionally, the comb teeth assembly is arranged in multiple rows along the axial direction of the hair curler housing, and each row of comb teeth is evenly spaced along the circumference of the hair curler housing.

[0012] Optionally, it also includes a handle housing, the top of which is connected to the connector, and a PCB control board and a power supply are housed inside.

[0015] Optionally, the connector is made of polycarbonate copolymer, the depth of the annular groove is 0.5mm-1mm, and the size of the circular groove is adapted to the size of the clamping hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs an open-type hollow cylindrical shell structure with an elastic clamping component in conjunction with a heating film. Since the outer diameter of the elastic clamping component in its natural state is larger than the inner diameter of the curling tube shell, the heating film can fit more tightly against the inner wall of the curling tube shell, helping to improve the uniformity of temperature distribution in the heating area. The fitting design of the clamping holes on the inner wall of the elastic clamping component and the heating film, combined with the snap-fit ​​engagement of the corresponding grooves on the connecting seat, enhances the fixing effect of the heating film on the elastic clamping component, reducing the possibility of displacement of the heating film during assembly and use. Simultaneously, the open-type structure design of the elastic clamping component simplifies the assembly operation of the heating component inside the curling tube shell and maintains the fit between the heating film and the inner wall of the curling tube shell during use, helping to maintain a relatively stable heating effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5 As shown, this utility model provides a wireless curling comb, characterized in that it includes: a curling barrel shell 1, a heating element, and a connecting seat 2. The curling barrel shell 1 has a hollow cylindrical structure, and its outer wall is provided with comb teeth 4. The connecting seat 2 is connected to the bottom end of the curling barrel shell 1. The heating element is assembled in the inner wall area of ​​the curling barrel shell 1. The heating element includes an elastic clamping member 3 and a heating film 7. The heating film 7 is wrapped around the elastic clamping member 3, inserted into the inner wall of the curling barrel shell 1, and connected to the connecting seat 2.

[0020] The elastic clamping member 3 is an open hollow cylindrical shell structure, and its outer diameter in its natural state is larger than the inner wall diameter of the hair curler shell 1.

[0021] The elastic clamping member 3 is made of elastic modified engineering plastic, specifically thermoplastic elastomer modified polypropylene copolymer.

[0022] The connecting seat 2 has an annular groove 5 and a circular hole groove 6 communicating with the annular groove 5. The inner wall of the elastic clamping member 3 has clamping holes 8 on opposite sides, and its lower edge is embedded in the annular groove 5. The clamping holes 8 are engaged in the circular hole groove 6.

[0023] The connecting seat 2 has an annular groove 5 and a circular hole groove 6 communicating with the annular groove 5. The inner wall of the elastic clamping member 3 has clamping holes 8 on opposite sides, and its lower edge is embedded in the annular groove 5. The clamping holes 8 are engaged in the circular hole groove 6.

[0024] The heating film 7 is adapted to the inner wall contour of the elastic clamping member 3 and the clamping hole 8, and is covered or wrapped and fixed to the inner wall of the elastic clamping member 3 and the two clamping holes 8.

[0025] The comb teeth assembly 4 is arranged in multiple rows along the axial direction of the hair curler shell 1, and each row of comb teeth is evenly spaced along the circumference of the hair curler shell 1.

[0026] It also includes a handle housing 9, the top of which is connected to the connecting base 2. The housing contains a PCB control board 10 and a power supply 11. The power supply 11 is electrically connected to the PCB control board 10. The heating film 7 is electrically connected to the PCB control board 10 through a wire. The wire passes through the circular hole groove 6 and the wiring channel of the connecting base 2.

[0027] The bottom of the handle housing 9 is fitted with a power switch 12 that is electrically connected to the PCB control board 10. The power switch 12 is a push-button switch, and its surface is flush with the bottom end face of the handle housing 9.

[0028] The power source 11 is a lithium-ion battery, which is fixed inside the handle housing 9 by a battery bracket.

[0029] The connector 2 is made of polycarbonate copolymer, the depth of the annular groove 5 is 0.5mm-1mm, and the size of the circular hole groove 6 is adapted to the size of the clamping hole 8.

[0030] Specifically, in this invention, an elastic clamping member 3 with an open hollow cylindrical shell structure is used in conjunction with a heating film 7. Since the outer diameter of the elastic clamping member 3 in its natural state is larger than the inner wall diameter of the hair curler shell 1, the heating film 7 can fit more tightly against the inner wall of the hair curler shell 1, which helps to improve the uniformity of temperature distribution in the heating area. The fitting design of the clamping hole 8 on the inner wall of the elastic clamping member 3 and the heating film 7, combined with the snap-fit ​​of the annular groove 5 and the circular hole groove 6 on the connecting seat 2, can enhance the fixing effect of the heating film 7 on the elastic clamping member 3 and reduce the possibility of displacement of the heating film 7 during assembly and use. At the same time, the open structure design of the elastic clamping member 3 makes the assembly operation of the heating component in the hair curler shell 1 easier, and can maintain the fit between the heating film 7 and the inner wall of the hair curler shell 1 during use, which helps to maintain a relatively stable heating effect.

[0031] Specifically, during assembly, the elastic clamp 3 is first slightly contracted along the opening direction so that its outer diameter fits the inner wall of the hair curler shell 1 and is then placed inside the tube. After release, the elastic clamp 3 naturally fits the inner wall of the hair curler shell 1. Then, the connecting seat 2 is aligned with the bottom end of the hair curler shell 1 so that the lower edge of the elastic clamp 3 is embedded in the circular groove 5, and the clamping hole 8 is precisely engaged with the circular groove 6 to complete the positioning and fixing of the heating component.

[0032] The working principle and usage process of this utility model are as follows: After pushing the power switch 12 at the bottom of the handle housing 9, the PCB control board 10 connects the power supply circuit of the power supply 11 and the heating film 7. After the heating film 7 is powered on, it generates heat. With the help of the structure design of the elastic clamp 3, whose outer diameter is larger than the inner wall diameter of the hair curler housing 1 in its natural state, its open cylindrical shell is tightly attached to the inner wall of the hair curler housing 1, so that the heat is evenly conducted to the whole of the hair curler housing 1. The user holds the handle housing 9 and combs the hair through the comb tooth assembly 4 on the outer wall of the hair curler housing 1, while wrapping the hair around the hair curler housing 1. The stable heat conducted by the body of the curler is used to curl and shape the hair. During use, the snap-fit ​​structure between the elastic clamp 3 and the connecting seat 2 maintains the fixed and attached state of the heating film 7, ensuring consistent heating. After styling, press the power switch 12 again to cut off the circuit and turn off the device.
