Preferably, the first mounting structure is a first flange and a second flange arranged on two sides of the root of the comb 100, the second mounting structure is a first insertion groove and a second insertion groove on the comb base 200, the structure of the first insertion groove is matched with the structure of the first flange, and the structure of the second insertion groove is matched with the structure of the second flange. The first insertion groove is provided on the left fixing frame along the length direction of the comb teeth base 200, and the second insertion groove is provided on the right fixing frame along the length direction of the comb teeth base 200. Referring to fig. 9, fig. 9 is a schematic structural view of a heat-conducting comb tooth device of an electrothermal hair straightening comb in embodiment 3 of the present invention. In embodiment 3 of the present invention, the first mounting structures are the first flange 112 and the second flange 113, the first flange 112 and the second flange 113 are respectively disposed on two sides of the root of the comb tooth 100 and respectively formed by protruding two sides of the root of the comb tooth 100, and the comb base 200 is provided with the second mounting structures (the first inserting groove 212 and the second inserting groove 213) matching with the first flange 112 and the second flange 113, so as to facilitate inserting the comb tooth 100 into the comb base 200 and improve the mounting efficiency. The mounting holes 111 on the comb teeth 100 comprise first mounting holes 109 for mounting the heating elements and second mounting holes 110 for mounting the temperature sensors, and the heating elements conduct heat to the comb teeth 100 in all directions during use, so that the heating efficiency can be improved, and the heat dissipation is reduced.

Referring to fig. 10, fig. 10 is a schematic structural view of comb teeth in a heat-conducting comb tooth device of an electrothermal hair straightening comb in embodiment 4 of the present invention, rectangular mounting holes 111 are provided at the root of the comb teeth 100 for mounting heating elements. The comb teeth with the structure can be arranged at the position where temperature monitoring is not needed in a plurality of comb tooth arrays without mounting holes of temperature sensors.

The invention adopts the tooth shape of the specific comb teeth, the splicing structure among the comb teeth and the detachable splicing structure of the comb tooth unit and the comb tooth base, thereby not only improving the hair straightening efficiency and accurately controlling the gap of the comb teeth, but also being convenient to install and improving the installation efficiency. The roots of the comb teeth are provided with mounting holes for mounting heating elements, and the heating elements are positioned inside the comb teeth after mounting, so that the heating elements can conduct heat to the comb teeth in an all-around manner, the heating efficiency is improved, and the heat dissipation is reduced; the two sides of the root of the comb teeth are provided with the first mounting structures, and the comb tooth base is correspondingly provided with the second mounting structures, so that the comb teeth and the comb tooth base can be conveniently mounted, the positioning accuracy is improved, and the mounting efficiency is improved; the comb teeth are arranged in a tongue shape, and the comb teeth are provided with curved transverse cross sections and curvature designs, so that the contact area with hair can be increased, and gaps between the adjacent comb teeth are reasonably arranged, so that the hair can be conveniently inserted, the hair can be effectively clamped, and the hair straightening efficiency is improved; the one side of broach sets up the arch, and the another side sets up the recess, and in the recess of the protruding embedding the place ahead broach of rear broach during the installation, convenient location has improved the installation effectiveness, has still strengthened the steadiness of a plurality of broach.
