[0042] In the utility model embodiment, as shown in the figure, Figures 1 to 3 The heating assembly 10 comprises a heat conducting member 11, a silica gel heat conducting sheet 12 and a ceramic heating element 13. The heat conducting member 11 has a hair ironing portion 111 and a mounting surface 112. The hair ironing portion 111 is used for contacting hair. The mounting surface 112 is located on the heat conducting member 11 and faces away from the hair ironing portion 111. The silica gel heat conducting sheet 12 is attached to the mounting surface 112 to be in thermal conduction connection with the heat conducting member 11. The ceramic heating element 13 has a heat transfer surface. The heat transfer surface is attached to the surface of the silica gel heat conducting sheet 12 which faces away from the mounting surface 112.

[0043] Specifically, the ceramic heating element 13 is substantially in the form of a sheet. The length of the silica gel heat conducting sheet 12 is not less than the length of the ceramic heating element 13. The width of the silica gel heat conducting sheet 12 is not less than the width of the ceramic heating element 13, so as to ensure that the silica gel heat conducting sheet 12 separates the ceramic heating element 13 and the heat conducting member 11. The silica gel heat conducting sheet 12 has good insulation and heat conductivity. At the same time, as a flexible material, the silica gel heat conducting sheet 12 can be well attached to the surface of the mounting surface 112 and the ceramic heating element 13 to reduce the gap and ensure good heat conduction without using silicone grease.

[0044] The utility model technical scheme sets the silica gel heat conducting sheet 12 between the heat conducting member 11 and the ceramic heating element 13. Since the silica gel heat conducting sheet 12 has good insulation, it can effectively prevent current leakage between the heat conducting member 11 and the ceramic heating element 13 and ensure electrical safety. At the same time, the silica gel heat conducting sheet 12 has good heat conductivity and flexibility. Compared with the way of coating a polymer-based insulating film on the ceramic heating element 13, the silica gel heat conducting sheet 12 can directly contact the surface of the ceramic heating element 13, so the heat conduction efficiency is higher. The silica gel heat conducting sheet 12 can also be tightly attached to the surface of the mounting surface 112 and the ceramic heating element 13 by applying pressure, so as to ensure that the heat conducting member 11, the silica gel heat conducting sheet 12 and the ceramic heating element 13 are in close contact, which can improve the heat conduction effect and avoid applying silicone grease and other heat conducting mediums.

[0045] In some embodiments, the heating assembly 10 further comprises an insulating member 14 which covers the side of the ceramic heating element 13 facing away from the silica gel heat conducting sheet 12. That is, the ceramic heating element 13 can be sandwiched by the insulating member 14 and the silica gel heat conducting sheet 12, so as to improve electrical safety.

That is, the two protruding ribs 113 can be used to confine the silica gel heat-conducting sheet 12 and the ceramic heating body 13 on the mounting surface 112, and facilitate the positioning and mounting of the silica gel heat-conducting sheet 12 and the ceramic heating body 13. In addition, when the heating assembly is used in a straightening iron, the protruding ribs 113 can be connected to the housing of the straightening iron. Optionally, the heat-conducting member 11 is made of aluminum or ceramic.

[0048] In some embodiments, each protruding rib 113 is provided at the end away from the mounting surface 112 with a protruding portion 114 extending towards the other protruding rib 113, and the protruding portion 114 and the ceramic heating body 13 are spaced apart to form a mounting space. In this way, the protruding ribs 113 and the protruding portions 114 form a hook, which can be used to connect to the housing of the straightening iron when the heating assembly is used in the straightening iron.

[0049] In some embodiments, the heating assembly 10 further comprises a mounting seat 15 and an elastic member. The mounting seat 15 is mounted on the side of the heat-conducting member 11 away from the ironing portion 111, and the elastic member is located between the ceramic heating body 13 and the mounting seat 15 to press the ceramic heating body 13 and the silica gel heat-conducting sheet 12 against the mounting surface 112. Specifically, the mounting seat 15 is connected to the heat-conducting member 11 to be fixed on the heat-conducting member 11, and the elastic member can be a spring, a spring sheet or a rubber block. In this way, the mounting seat 15 and the heat-conducting member 11 can be assembled into an integral module, and when the straightening iron is assembled, the mounting seat 15 can be connected to the housing of the straightening iron, which facilitates the assembly of the straightening iron. Of course, in other embodiments, the ceramic heating body 13 and the silica gel heat-conducting sheet 12 can be pressed against the heat-conducting member 11 by the structure on the housing of the straightening iron when the straightening iron is assembled.

Specifically, the clamping groove 115 is provided through at both ends in the length direction of the rib 113, and the mounting seat 15 can be mounted from one end of the rib 113, so that the clamping protrusion 153 slides into the clamping groove 115. In this way, the heat conduction piece 11 can be better limited in the receiving groove 152, and installation is facilitated.

[0051] Optionally, the mounting seat 15 includes two seat bodies 151, each of which is provided with a receiving groove 152, and the receiving groove 152 on each seat body 151 is provided open at one end. During installation, one end of the heat conduction piece 11 can be inserted into the receiving groove 152 of one of the seat bodies 151, and the other end can be inserted into the receiving groove 152 of the other seat body 151, and after installation, the open ends of the two seat bodies 151 are butted. In this way, the length of the single seat body 151 matched with the rib 113 can be reduced, and installation is facilitated.

[0052] In some embodiments, the heat generating assembly 10 further includes a heat-conducting adhesive tape covering the hair straightening part 111. In operation, the heat of the heat conduction piece 11 can be conducted to the heat-conducting adhesive tape, and the hair straightening is achieved by the heat-conducting adhesive tape contacting the hair. Compared with the method of directly contacting the hair with the heat conduction piece 11, the temperature of the heat-conducting adhesive tape is relatively low, and the heat-conducting adhesive tape has a slight softening effect at the use temperature, which can reduce the damage to the hair quality. Moreover, the heat-conducting adhesive tape is relatively smooth when contacting the hair, so that the hair is more smooth when being straightened. In addition, when contacting the hair through the heat-conducting adhesive tape, the heat-conducting adhesive tape also has a good antistatic effect, which can prevent the hair from being entangled, knotted and frizzy due to static electricity.

[0053] Optionally, the heat-conducting adhesive tape is an acetic acid cloth, so as to have a better slight softening effect and antistatic effect. In other embodiments, the heat-conducting adhesive tape is a silica gel cloth.

In this way, the number of the ceramic heating bodies 13 is increased, the distance between the installation surface 112 and the outer wall surface of the heat-conducting piece 11 is short, the heating speed of the heating assembly 10 is improved, and the two ceramic heating bodies 13 are distributed in the circumferential direction of the heat-conducting piece 11, so that the heat-conducting piece 11 is uniformly heated.
