[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0033] As Figure 1 、 Figure 2 and Figure 3 shown, the present utility model discloses a comb tooth structure 400, which is specifically assembled by a heat-conducting comb assembly 10, a heating element 70, a pressing plate assembly 60 and a fixing frame 30. The heating element 70 is pressed and attached to the surface of the heat-conducting comb assembly by the pressing plate assembly, and the whole is assembled by the fixing frame 30, so that the entire comb tooth structure 400 forms a whole, which is convenient for subsequent processes. When assembling the straightening comb, only the assembled comb tooth structure needs to be installed in the corresponding position to complete the assembly, and its installation is convenient and the efficiency is high.

[0034] The heat-conducting comb assembly 10 has a plurality of heat-conducting comb teeth 11 arranged in an array on its front surface, and an installation groove 12 on its back surface. The heat-conducting comb assembly 10 is made of metal, preferably made of a material with good heat-conducting performance such as aluminum. A plurality of heat-conducting comb teeth are integrally formed on its surface, and a plurality of columns of heat-conducting comb teeth are arranged on its front surface. In this embodiment, 3 columns are adopted, and a groove is formed between each column of heat-conducting comb teeth.

[0035] An installation groove is formed at the bottom of the heat-conducting comb assembly. One end of the installation groove is provided with an opening, which is convenient for leading out the lead of the heating element placed therein. The opening can also be a hole structure.

[0036] The heating element 70 is placed in the installation groove 12. The heating element uses MCH (ceramic heating element), which is in the shape of a flat long strip and has a flat surface, so as to be in uniform contact with the bottom of the installation groove, which is convenient for heat conduction to the heat-conducting comb teeth.

[0037] The pressing plate assembly 60 is used to make the heating element closely adhere to the heat conduction comb assembly 10. The main function of this pressing plate assembly is to provide the force to tightly press the heating element on the bottom surface of the installation groove. It is composed of a pressing plate and a compression spring. The pressing plate increases the contact area, and the compression spring is used to provide pressure. At the same time, the compression spring is formed by bending the spring strip multiple times, so that when restricted by the fixing frame, it can generate a force on the pressing plate. The compression spring can also adopt structures such as an annular compression spring or a spring sheet, and is mainly restricted by the fixing frame to form a pressure towards the pressing plate when compressed.

[0038] The fixing frame 30 is used to fix the pressing plate assembly 60 on the back of the heat conduction comb assembly 10. It is specifically in a rectangular frame structure, and there are avoidance structures 31 on both sides thereof that are adapted to the positioning posts 13. It is arranged along the edge of the installation groove to realize the restriction of the compression spring and the pressing piece, and make the pressing piece assembly and the heating element firmly fixed in the installation groove. At the same time, the design of the rectangular frame can reduce its cost.

[0039] The avoidance structure 31 is mainly used for avoiding the positioning posts. It can be an annular sleeve that directly allows the positioning posts to pass through, or can be designed into a positioning post structure by itself, or directly sleeved above the positioning posts.

[0040] After the heat conduction comb assembly 10 and the heating element 70 are assembled by the pressing plate assembly 60 and the fixing frame 30, they form an integral body, that is, the heating element and the pressing plate assembly are fixed by the fixing frame, and one side of the pressing plate assembly is restricted by the fixing frame, thereby applying pressure to the heating element, making the heating element tightly fit in the installation groove and closely adhere to it, improving the heat conduction efficiency.

[0041] There are several positioning posts 13 on the back of the heat conduction comb assembly 10. The positioning posts 13 are distributed on both sides of the installation groove 12. The design of the positioning posts facilitates better alignment during subsequent assembly and ensures the accuracy of the installation position. It can be directly integrally formed by the heat conduction comb assembly or directly realized by the fixing frame.

[0042] In this embodiment, it is integrally formed on the back of the heat conduction comb assembly. There are 4 of them, which are symmetrically arranged on both sides of the installation groove respectively. At the same time, it can also be in an asymmetric manner, or can be formed by the fixing frame above the installation groove. The design of this positioning post is mainly for positioning the installation position with the straight hair comb during assembly, so its setting position can be designed at different positions according to actual needs.

[0043] There is a heat insulation sleeve 50 outside the positioning post 13. The heat insulation sleeve is made of heat insulation rubber and is in a circular ring shape, sleeved on the outside of the positioning post, or can be directly sleeved on the avoidance structure of the fixing frame, playing a heat insulation effect to avoid heat transfer to the shell of the straight hair comb.

[0044] A positioning ring 40 is also provided on the positioning post 13. Preferably, the design of adding the positioning ring can prevent the positioning post integrally formed by the heat-conducting comb assembly from directly contacting the housing of the straightening comb, further improving the heat insulation effect and also playing a positioning role.

[0045] An NTC resistor 80 is also provided in the installation groove 12. The NTC resistor is used for temperature detection so as to realize temperature adjustment. And the NTC resistor 80 is arranged on one side of the heating element 70 and is fixed in the installation groove 12 by the pressing plate assembly 60.

[0046] One side of the pressing plate 61 extends outward to form an arc-shaped pressing member 63 for restricting the NTC resistor 80. The pressing surface of the arc-shaped pressing member matches the surface of the NTC resistor, thereby restricting the position of the NTC resistor in the installation groove to remain unchanged, so that the distance between it and the heating element always remains the same, and further making the temperature detection accuracy more accurate, so that there will be no temperature fluctuations when controlling the heating element during use.

[0047] A fixing plate 20 for fixedly connecting with the straightening comb is also provided outside the heat-conducting comb assembly 10. The fixing plate is installed and matched with the lower side of the heat-conducting comb assembly, and at the same time, the bottom of it realizes the bottom limit by using the avoiding structure of the fixing frame, thereby completing the fixation of the fixing plate and the heat-conducting comb assembly.

[0048] As Figure 4 and Figure 5 shown, the present utility model also discloses a straightening comb, which includes a housing 100. One end of the housing 100 is set as a holding part, a control component 300 is arranged in the holding part, the other end of the housing is provided with a comb tooth assembly groove 110, and an opening for inserting an installation base 500 is provided at one end of the housing 100. The opening is communicated with the comb tooth assembly groove. The above-mentioned comb tooth structure 400 is arranged in the comb tooth assembly groove 110, and the comb tooth structure 400 is fixedly connected with the installation base 500.

[0049] Both ends of the housing 100 are provided with openings. The upper opening is used for the installation of the installation base 500, and the lower opening is used for the installation of the control component 300. Both are fixed in the housing by means of plugging and unplugging. Among them, the installation base 500 enters the comb tooth assembly groove 110 from the opening, and then the comb tooth structure can be installed through the comb tooth assembly groove and fixedly connected with the installation base by using screws, thereby completing the assembly of the comb tooth structure. After the assembly is completed, the comb tooth fastener 200 can be buckled on the comb teeth.

[0050] As Figure 5The surface of the comb fastener is provided with a number of comb teeth, which are arranged in multiple longitudinal rows and are respectively placed between the heat-conducting comb teeth. The size of the comb teeth is smaller than the design of the heat-conducting comb teeth, and the heat-conducting comb teeth are arranged in an alternating manner with the comb teeth, that is, the heat-conducting comb teeth and the comb teeth are not in the same row, and the heat-conducting comb teeth are placed between two adjacent comb teeth. As Figure 8 shown, the alternating design can improve the grasping force. When performing the straightening operation, it can better grasp the hair, and make the hair contact the heat-conducting comb teeth more closely, improving the straightening efficiency.

[0051] As Figure 7 shown, at the same time, the upper surface A of the first comb teeth is designed as an inwardly concave arc surface, and the heat-conducting comb teeth are also designed as arc surfaces accordingly, so as to better fit the scalp and conform to ergonomics.

[0052] Both the first comb teeth and the heat-conducting comb teeth gradually narrow from bottom to top to form a hair guiding channel, which can better gather the hair between the two, better grasp the hair, and perform the straightening operation on the hair.

[0053] The installation base is provided with a number of positioning grooves 510, which play a role in positioning with the positioning ring, facilitating the accurate installation of the comb structure in the installation base and ensuring the accuracy of the installation position each time.

[0054] The lower side opening of the housing is used to install the control component 300. The control component includes a bracket 310 that slides relative to the housing. The bracket 310 is divided into two spaces. One space is used to install the battery 320, and the other space is used to place the control circuit board 330. The control circuit board is connected to the heating element and the NTC resistor through wires to play a control role. An operation key for operating the control circuit board can be set at any position of the holding part. The operation key can be a touch switch, a toggle switch, a touch switch, etc.

[0055] At the same time, the operation key can also be designed at the end of the control component, that is, at the end handle of the whole straightening comb. If it is directly designed on the control component, there is no need to modify the housing, which can maintain the integrity of the whole housing and improve the aesthetics.

[0056] The embodiments should not be regarded as limitations of the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
