[0027] The hair curler of the preferred embodiment of the present invention is as follows Figure 1-6As shown, it includes a handle 10, a heating portion 20 provided at the front end of the handle 10, and a heat-conducting clip 30 hinged on the side wall of the front end of the handle 10; the heat-conducting clip 30 is side by side with the heating portion 20; a first electric heating element 40 is provided on the heat-conducting clip 30; when the heat-conducting clip 30 is closed, the inner and outer side walls of the heat-conducting clip respectively form two heating positions for heating the hair, thereby taking into account both the uniformity and ease of operation of heating on both sides of the hair while keeping the overall volume change small, and providing a better user experience; in actual use, the hair can be continuously and evenly heated by the two heat sources of the two heating positions (i.e., the first electric heating element 40 and the heating portion), resulting in a better and faster qualitative effect, and after the user wraps the hair around the closed heating portion and the heat-conducting clip, the outer side of the heat-conducting clip still maintains a relatively high temperature to meet the requirements for curling the hair.

[0028] Among them, the heating part 20 and the handle 10 are both cylindrical, and the overall assembly shape of the two is also cylindrical. Of course, the handle 10 can also be of other shapes, as long as it meets the conditions of convenience for daily use; specifically, the heating part 20 includes a heat pipe 21, which is generally made of aluminum pipe or iron pipe, and the heating part 20 also includes a second electric heating element 22 installed inside the heat pipe 21. The second electric heating element 22 generally adopts any one of a heating film, a ceramic heating plate, a PTC heating plate or a thick film heating plate.

[0029] The handle 10 is coaxially connected to the rear end of the heat pipe 21 through the connecting nozzle 50, and a plug 60 and a decoration 70 are installed at the front end of the heat pipe 21 to beautify the appearance and protect the internal components.

[0030] In addition, in order to facilitate assembly and avoid interference from high temperatures, the control panel 80 and the buttons 90 are both arranged on the handle 10, and the handle 10 is designed to be a structure that can be radially disassembled in half. The handle 10 specifically includes an upper cover 11 and a lower cover 12, and the control panel 80 is arranged in a cavity between the upper cover 11 and the lower cover 12; wherein, in order to take into account both the convenience of processing and the beautification of appearance, the upper cover 11 and the lower cover 12 are divided into an inner layer and an outer layer. The upper cover 11 is specifically an upper body 111 and an upper cover 112 provided on its outer side wall, and the lower cover 12 is specifically a lower body 121 and a lower cover 122 provided on its outer side wall. This design can also hide the screw holes and snap-in positions on the upper body 111 and the lower body 121 that affect the appearance.

[0031] A power line 100 connected to the control panel 80 is provided at the rear end of the handle 10 to provide driving power and power to the first / second electric heating element.

[0032] In this embodiment, the first electric heating element 40 is embedded in the interior of the thermally conductive clip 30, and the thickness of the thermally conductive clip 30 is less than or equal to 5 mm to ensure the lightness and compactness of its structure and avoid affecting the appearance due to excessive thickness.

[0033] In this embodiment, the first electric heating element 40 is any one of a heating film, a ceramic heating plate, a PTC heating plate or a thick film heating plate. Preferably, this embodiment specifically adopts a heating film and its thickness is less than or equal to 3 mm to avoid excessively increasing the overall thickness of the thermally conductive clip 30. Of course, other thicknesses can also be selected according to actual conditions.

[0034] In this embodiment, a mounting groove 110 is provided on a side wall of the thermally conductive clip 30 facing away from the heating portion 20, and the first electric heating element 40 is disposed in the mounting groove 110 to further reduce the overall thickness of the thermally conductive clip 30, facilitate the installation and fixation of the first heating element, and beautify the appearance.

[0035] In this embodiment, the first electric heating element 40, the mounting groove 110 and the thermally conductive clip 30 are all in the shape of long strips. The mounting groove 110 is arranged along the length direction of the thermally conductive clip 30. The thermally conductive clip is also provided with a clamping fixture 130 for fixing the first electric heating element 40 in the mounting groove 110 to ensure the stability of the structural parts and avoid shaking of the components during use, producing abnormal noise or position movement affecting the use effect.

[0036] Furthermore, the clamping fixture is an arc-shaped plate whose outer contour is larger than the contour of the mounting groove, and an interlayer member 120 is provided between the heating film and the clamping fixture. The interlayer member 120 is silicone. When assembled in place, the clamping fixture 130 seals the interlayer member 120 and the first electric heating member 40 in the mounting groove 110, and presses the first electric heating member 40 against the bottom surface of the mounting groove, so as to further make the heating film more stable after assembly, and to buffer the situation where the local clamping force generated by the assembly is too large and causes damage to the heating film.

[0037] Among them, in order to further ensure the neatness of the overall appearance of the product, an opening 1101 for wiring is provided at the rear end of the bottom surface of the installation groove 110, and a U-shaped rib 140 is provided on the concave side of the heat conductive clip 30, which is half surrounded by the edge of the opening 1101. The opening 1101 of the U-shaped rib 140 faces the handle 10, and a partition 150 is provided at the lower end of the U-shaped rib 140 to seal the lower end opening. The partition 150 is L-shaped, and the outer wall of the longitudinal end of the partition 150 is snap-connected with the inner wall of the connecting part of the two arms of the U-shaped rib 140. After installation, the left and right sides of the partition 150 are tightly pressed against the inner walls of the two arms of the U-shaped rib 140, and a wiring channel 160 facing backward is enclosed by the partition 150 and the U-shaped rib 140 to facilitate the connection of the heating film wires to the inside of the handle 10.

[0038] Furthermore, the connecting nozzle 50 is also cylindrical, with its front end inserted into the heat pipe 21 and its rear end covered and fixed by the handle 10 to achieve the connection between the two.

[0039] In this embodiment, the heat-conducting clip 30 is arc-shaped and the curvature of its concave surface is consistent with the curvature of the side wall of the heating portion 20. The concave surface of the heat-conducting clip 30 and / or the outer wall of the heating portion are provided with a friction-reducing layer component (not shown). The design of this layer component can reduce the pulling force on the hair when the user clamps the hair, ensuring smooth perming and pulling along the hair. The layer component can be a coating or a sheet-like component. The coating can be a Teflon coating, taking into account the requirements of high-temperature stability and low friction. The sheet-like component can also be made of low-friction and high-temperature resistant materials such as PTFE, PEEK or fluoroplastics, but the excellent degree of thermal conductivity needs to be taken into consideration.

[0040] In this embodiment, the rear end of the thermally conductive clip 30 has a pressing extension portion 170 that is convenient for the user to press and open the thermally conductive clip 30. Furthermore, the handle is provided with an elastic return member 180 that provides an elastic return force for the pressing extension portion 170. When the thermally conductive clip 30 is in the closed state, the elastic return member 180 presses outward against the end of the pressing extension portion 170 away from the rotating shaft 31 of the thermally conductive clip 30, so that the thermally conductive clip 30 and the pressing extension portion 170 form a lever structure with its rotating shaft as the turning point. When the elastic return member 180 presses outward against the pressing extension portion 170, the thermally conductive clip 30 can be kept in contact with the outer wall of the heating portion 20; wherein, the elastic return member 180 can be a spring or a torsion spring or a U / V-shaped and elastic metal spring.

[0041] Furthermore, a groove 51 is provided on the side wall of the connecting nozzle 50, and the protrusion 171 on the lower side of the pressing extension portion 170 is hinged in the groove 51 through the rotating shaft 31. A through hole is provided on the rear side wall of the groove 51, which is connected to the inner cavity of the handle for the wires of the heating film to pass through; when assembled in place, the through hole is directly opposite to and connected to the wiring channel 160, and also serves the purpose of hiding the wiring.

[0042] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
