[0024] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] As shown in the figure, a double-row heated straight hair comb includes a shell 1, a heating component 2 and a comb tooth cover 3. The front end of the shell 1 is formed with a mounting cavity 11, and the heating component 2 is arranged in the mounting cavity 11. The heating component 2 includes a heating element 21, a mounting plate 22, a first tooth plate 23 and a second tooth plate 24. The first tooth plate 23 and the second tooth plate 24 are respectively formed with two rows of first comb teeth 231 and two rows of second comb teeth 241. The second tooth plate 24 is provided with a plurality of mounting holes 242 located between two adjacent second comb teeth 241 for the first comb teeth 231 to pass through. The heating element 21 is arranged on the mounting plate 22, and the first tooth plate 23 is stacked on the first tooth plate 23. On the heating element 21, the second tooth plate 24 is stacked on the first tooth plate 23 so that the first comb teeth 231 pass through the mounting holes 242, and the two side ends of the mounting plate 22 are bent and folded on the second tooth plate 24. Through the limiting effect of the mounting plate 22, the heating element 21, the first tooth plate 23 and the second tooth plate 24 are stably stacked to form a heating assembly. The first tooth plate 23 is provided with a first heat dissipation port 232 located between the two rows of first comb teeth 231, and the first tooth plate 23 is provided with a heat dissipation groove 233 on the surface facing the heating element 21, which penetrates the first tooth plate 23 to one side and is connected to the first heat dissipation port 232, and the heat dissipation groove 233 connects the first heat dissipation port 232 with the mounting cavity 11.

[0026] In the above structure, the first comb teeth 231 are located between two adjacent second comb teeth 241 after passing through the mounting holes 242. The heat generated by the heating element 21 connected to the electronic control is first conducted to the first tooth plate 23 in contact with it, and the first tooth plate 23 then conducts the heat to the second tooth plate 24 in contact with it. The first tooth plate 23 and the second tooth plate 24 simultaneously conduct the heat to the first comb teeth 231 and the second comb teeth 241 integrally formed therewith, so as to perform a straightening treatment on the hair stuck between the first comb teeth 231 and the second comb teeth 241 when combing the hair. During the above heat conduction process, the heat accumulated at the contact point between the heating element 21 and the first tooth plate 23 (that is, the area between the two rows of first comb teeth 231 on the first tooth plate 23) is dissipated into the mounting cavity 11 through the first heat dissipation port 232 and the heat dissipation groove 233, preventing local overheating of the first tooth plate 23 and the second tooth plate 24, thereby ensuring that the temperature of the first comb teeth 231 and the second comb teeth 241 is balanced, thereby ensuring high straightening efficiency while avoiding damage to the hair.

[0027] In addition, based on the above structure, a plurality of positioning grooves 234 are formed on the first tooth plate 23, and a plurality of positioning protrusions 243 are formed on the second tooth plate 24 that match the positioning grooves 234 and are inserted into the positioning grooves 234 one by one. The cooperation between the positioning protrusions 243 and the positioning grooves 234 limits the relative displacement between the first tooth plate 23 and the second tooth plate 24, so that the first tooth plate 23 and the second tooth plate 24 can be more stably stacked, thereby ensuring the stability between the first comb teeth 231 and the second comb teeth 241, so as to more stably cooperate to straighten the hair stuck between the first comb teeth 231 and the second comb teeth 241.

[0028] In addition, based on the above structure, a second heat dissipation port 12 opposite to the heat dissipation slot 233 is provided on the side wall of the installation cavity 11, so that the installation cavity 11 is connected with the rear end of the shell 1. Through the action of the second heat dissipation port 12, the heat accumulated at the contact point between the heating element 21 and the first tooth plate 23 can be dissipated to the rear end of the shell 1 through the second heat dissipation port 12, that is, the heat dissipation space available for heat flow is increased, further preventing local overheating of the first tooth plate 23 and ensuring the temperature balance of the first comb teeth 231 and the second comb teeth 241.

[0029] In addition, based on the above structure, a mounting foot 235 is formed on each of the four corners of the first tooth plate 23, and four mounting grooves 13 matching the mounting feet 235 are formed on the side walls of the mounting cavity 11. The bottom wall of the mounting groove 13 is higher than the bottom wall of the mounting cavity 11. The mounting foot 235 is placed in the mounting groove 13 to form a first thermal insulation gap 14 between the mounting plate 22 and the bottom wall of the mounting cavity 11. The first thermal insulation gap 14 isolates the mounting plate 22 from the mounting cavity 11 to avoid direct contact between the mounting plate 22 and the shell 1, thereby preventing the heat of the heating element 21 from being directly transferred to the shell 1 and causing overheating of the shell 1, thereby playing a scalding prevention role.

[0030] In addition, on the basis of the above structure, the shell 1 is composed of an upper shell 15 and a lower shell 16, and the installation cavity 11 is arranged on the upper shell 15. A second thermal insulation gap 17 connected to the installation cavity 11 is formed between the front end of the upper shell 15 and the front end of the lower shell 16. The second thermal insulation gap 17 isolates the outer wall of the installation cavity 11 from the lower shell 16 and reduces the heat conducted to the lower shell 16 (the user may touch the lower shell 16 during use) to play a scalding prevention role. The second thermal insulation gap 17 connected to the installation cavity 11 also increases the dissipation space of the heat accumulated at the contact point between the heating element 21 and the first tooth plate 23, thereby further preventing local overheating of the first tooth plate 23 and ensuring the stable balance of the first comb teeth 231 and the second comb teeth 241.

[0031] In addition, based on the above structure, the first comb teeth 231 and the second comb teeth 241 are tongue-shaped, so that the first comb teeth 231 and the second comb teeth 241 have curved tooth surfaces. The first comb teeth 231 and the second comb teeth 241 with curved tooth surfaces make the channel for the hair to pass through formed therebetween wavy. While increasing the contact area between the first comb teeth 231 and the second comb teeth 241 and the hair to improve the hair straightening efficiency, it also creates a certain resistance when the hair passes between the first comb teeth 231 and the second comb teeth 241, thereby better grabbing the hair and achieving better hair straightening efficiency.

[0032] In addition, based on the above structure, a plurality of anti-scalding teeth 31 surrounding the first comb teeth 231 and the second comb teeth 241 are formed on the comb tooth cover 3. The thickness of the anti-scalding teeth 31 gradually decreases from bottom to top, so that the gap between two adjacent anti-scalding teeth 31 gradually increases from bottom to top. When combing hair, the larger gap at the top of the two anti-scalding teeth 31 makes it easier for hair to be stuck between the two anti-scalding teeth 31 and between the first comb teeth 231 and the second comb teeth 241, while the smaller gap at the bottom of the two anti-scalding teeth 31 has a certain gripping effect on the hair stuck between the two anti-scalding teeth 31, thereby achieving better hair straightening efficiency.

[0033] When the comb tooth cover 3 is in the state of being pressed down, the hair straightening comb 31 of the present invention will be easily broken.

[0034] The second retaining plate 51 is engaged with the second retaining hole 162 so that the mounting snap ring 5 presses the decorative plate 4 onto the lower shell 16. The second retaining plate 51 is engaged with the second retaining hole 162 so that the mounting snap ring 5 presses the decorative plate 4 onto the lower shell 16. The cooperation between the second retaining plate 51 and the second retaining hole 162 limits the displacement of the mounting snap ring 5 relative to the lower shell 16, so that the mounting snap ring 5 can detachably fix the decorative plate 4 on the shell by tightly abutting the mounting edge 41. The decorative plate 4 is located on the back of the shell and can play a decorative role as well as a scalding role. In addition, the second retaining plate 51 is engaged with the second retaining hole 162 so that the mounting snap ring 5 presses the decorative plate 4 onto the lower shell 16.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
