Technical Field

[0001] This utility model relates to the field of hair styling equipment technology, and in particular to a hair curler. Background Technology

[0002] With the improvement of people's living standards, hair styling is receiving more and more attention, and there are many kinds of hair styling devices used. Curling is a styling option that is frequently used when styling hair. Currently, the curling tools on the market are generally hair dryers with curling combs, or clamp-type manual curling irons / sticks. Curling irons are a kind of DIY hair styling tool, and hairdressers in hair salons and hair parlors will use a set of curling iron tools.

[0003] The current drawback of hair curlers is that although the design of the heat-conducting clips and heating tubes can fit snugly against and heat the hair, there is still a certain gap between the heating rod and the clips during actual use. This gap can cause a temperature difference between the clips and the heating rods, resulting in uneven heating of the hair.

[0004] Therefore, this solution requires a new type of curling iron to address the aforementioned problems. Utility Model Content

[0030] The preferred embodiment of the hair curler of this utility model, such as Figure 1-6As shown, it includes a handle 10, a heating part 20 located at the front end of the handle 10, and a heat-conducting clip 30 hinged to the front side wall of the handle 10; the heat-conducting clip 30 is arranged side by side with the heating part 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 form two heating positions for heating the hair, thereby achieving both uniform heating of the hair on both sides and ease of operation with minimal changes in overall volume, resulting in a better user experience; in actual use, the hair can be continuously and evenly heated by the two heat sources (i.e., the first electric heating element 40 and the heating part) at the two heating positions, resulting in better and faster styling effect, and after the user wraps the hair around the closed heating part and heat-conducting clip, the outer side of the heat-conducting clip still has a high temperature to meet the requirements for curling the hair.

[0031] Both the heating element 20 and the handle 10 are cylindrical, and their overall assembly shape is also cylindrical. Of course, the handle 10 can also be other shapes, as long as they meet the requirements for convenient daily use. Specifically, the heating element 20 includes a heat-conducting pipe 21, which is generally made of aluminum or iron. The heating element 20 also includes a second electric heating element 22 installed inside the heat-conducting pipe 21. The second electric heating element 22 is generally made of any one of heating film, ceramic heating element, PTC heating element or thick film heating element.

[0032] The handle 10 is coaxially connected to the rear end of the heat pipe 21 via the connecting nozzle 50. A plug 60 and a decorative element 70 are installed at the front end of the heat pipe 21 to beautify the appearance and protect the internal components.

[0033] In addition, to facilitate assembly and avoid interference from high temperatures, the control board 80 and buttons 90 are both located on the handle 10. The handle 10 is designed to be radially detachable in half. The handle 10 specifically includes an upper cover 11 and a lower cover 12, with the control board 80 located in the cavity between the upper cover 11 and the lower cover 12. To balance ease of processing and aesthetic appeal, both the upper cover 11 and the lower cover 12 are divided into inner and outer layers. The upper cover 11 specifically consists of an upper body 111 and an upper cover 112 located on its outer side wall. The lower cover 12 specifically consists of a lower body 121 and a lower cover 122 located on its outer side wall. This design also conceals the screw holes and clip positions on the upper body 111 and the lower body 121, which are structural components that affect aesthetics.

[0034] The handle 10 has a power cord 100 at the rear end that connects to the control board 80 to provide drive power and power the first / second electric heating element.

[0035] In this embodiment, the first electric heating element 40 is embedded inside the heat-conducting clip 30, and the thickness of the heat-conducting clip 30 is less than or equal to 5mm, so as to ensure the lightweight and compactness of its structure and avoid excessive thickness affecting the appearance.

[0036] In this embodiment, the first electric heating element 40 is any one of a heating film, a ceramic heating element, a PTC heating element, or a thick film heating element. Preferably, this embodiment uses a heating film with a thickness of less than or equal to 3 mm to avoid excessively increasing the overall thickness of the heat-conducting clip 30. Of course, other thicknesses can also be selected according to the actual situation.

[0037] In this embodiment, the heat-conducting clip 30 has a mounting groove 110 on the side wall opposite to the heating part 20. The first electric heating element 40 is disposed in the mounting groove 110 to further reduce the overall thickness of the heat-conducting clip 30, facilitate the installation and fixation of the first heating element, and improve the appearance.

[0038] In this embodiment, the first electric heating element 40, the mounting groove 110, and the heat-conducting clamp 30 are all elongated. The mounting groove 110 is arranged along the length of the heat-conducting clamp 30. The heat-conducting clamp is also provided with a clamping fastener 130 to fix the first electric heating element 40 in the mounting groove 110, so as to ensure the stability of the structural components and avoid the components from shaking and making abnormal noise or moving in position during use, which would affect the use effect.

[0039] Furthermore, the clamping fastener is an arc-shaped plate with an outer contour larger than that of the mounting groove. A partition 120 is also provided between the heating film and the clamping fastener. The partition 120 is made of silicone. When assembled, the clamping fastener 130 seals the partition 120 and the first electric heating element 40 in the mounting groove 110 and presses the first electric heating element 40 against the bottom surface of the mounting groove. This further stabilizes the heating film after assembly and buffers the situation where excessive local clamping force during assembly causes damage to the heating film.

[0040] To further ensure the overall neatness of the product's appearance, the bottom rear end of the mounting groove 110 has a wiring opening 1101, and the concave side of the heat-conducting clip 30 has a U-shaped rib 140 that partially surrounds the edge of the opening 1101. The opening 1101 of the U-shaped rib 140 faces the handle 10, and the lower end of the U-shaped rib 140 has a partition 150 that seals its lower opening. The partition 150 is L-shaped, and the outer wall of the longitudinal end of the partition 150 is snapped to 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 abut against the inner walls of the two arms of the U-shaped rib 140. The partition 150 and the U-shaped rib 140 together form a wiring channel 160 with the window facing backward, so as to facilitate the connection of the heating film's wires into the handle 10.

[0041] Furthermore, the connecting nozzle 50 is also cylindrical, with its front end inserted into the heat pipe 21, while its rear end is covered and fixed by the handle 10 to achieve the connection between the two.

[0042] 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 part 20. The concave surface of the heat-conducting clip 30 and / or the outer side wall of the heating part have 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 the smoothness of the hair straightening. The layer component can be a coating or a sheet component. The coating can be a Teflon coating, which takes into account the requirements of high temperature stability and low friction. The sheet component can also be made of low friction and high temperature resistant materials such as PTFE, PEEK or fluoroplastics, but the degree of thermal conductivity needs to be considered.

[0043] In this embodiment, the rear end of the heat-conducting clip 30 has a pressing extension 170 that facilitates the user to press and open the heat-conducting clip 30. Furthermore, the handle is provided with an elastic reset member 180 that provides an elastic reset force to the pressing extension 170. When the heat-conducting clip 30 is closed, the elastic reset member 180 presses against the end of the pressing extension 170 away from the pivot 31 of the heat-conducting clip 30, so that the heat-conducting clip 30 and the pressing extension 170 form a lever structure with their pivot as the pivot point. When the elastic reset member 180 presses against the pressing extension 170, the heat-conducting clip 30 can be kept attached to the outer wall of the heating part 20. The elastic reset member 180 can be a spring, a torsion spring, or a U / V shaped elastic metal spring.

[0044] Furthermore, a groove 51 is provided on the side wall of the connecting nozzle 50. The protrusion 171 on the lower side of the pressing extension 170 is hinged in the groove 51 via a pivot 31. A through hole communicating with the inner cavity of the handle is provided on the rear side wall of the groove 51 to allow the heating film wire to pass through. When assembled, the through hole is directly connected to the wiring channel 160, thus also concealing the wiring. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
