[0002] Combs are common daily necessities. With the advancement of technology and to cater to people's needs, there are many types of combs. Among them, a hair straightening comb is a common functional comb. Because it can use heating to achieve a quick hair straightening effect, it is loved by beauty lovers with messy hair or other people who have hair straightening care needs.

[0003] Existing hair straightening combs are usually thick and heavy, occupy a large space, and are inconvenient to store and carry out; they are also heavy to the touch, and the user's arms and wrists are easily fatigued during the hair straightening care process. At the same time, existing hair straightening combs are all provided with multiple rows of comb teeth in the width direction. When using the hair straightening comb, the user usually holds the hair straightening comb in accordance with the usage habits so that the width direction of the hair straightening comb is roughly consistent with the length direction of the hair, and moves the hair straightening comb along the length direction of the hair to perform hair straightening care. During use, the existing hair straightening comb has a large contact range in the length direction of the hair, and the hair straightening comb often needs to be moved along the length direction of the hair to achieve the hair straightening effect. Therefore, when the user only needs to perform hair straightening care on a local short range in the length direction of the hair or on shorter hair, due to the limitation of the width of the hair straightening comb, this operation is often difficult to achieve, or difficult to operate, and the effect achieved is not ideal.

[0004] It can be seen that users still have the above-mentioned problems when using existing hair straightening combs, which leads to the low frequency of use of the purchased hair straightening combs by users, and this also becomes a limiting factor for consumers when purchasing hair straightening combs. Summary of the invention

[0005] The purpose of the present invention is to provide an ultra-thin hair straightening comb to solve the technical problem that the hair straightening comb in the prior art is relatively thick and heavy, which causes the users to have the above-mentioned troubles and affects the user experience.

[0006] The ultra-thin hair straightening comb provided by the present invention comprises a comb body and a heating component, wherein the comb body is provided with a plurality of comb teeth arranged in a straight line in a row along its length direction, and at least part of the plurality of comb teeth are thermally conductive; the heating component is fixed on the comb body to heat the comb teeth with thermal conductivity; and the thickness of the comb body is not greater than 15 mm.

The movable tooth is connected with a movable plate, the movable plate is slidably connected to the heat-conducting mounting plate, and the movable tooth can approach or move away from the fixed tooth adjacent to it under the sliding action of the movable plate.

[0010] Further, the heat-conducting mounting plate includes a plate-shaped mounting portion. One end of one side plate surface of the mounting portion is bent to form a chute. The fixed teeth are spaced and mounted on the bottom wall of the chute. A positioning hole is arranged on the chute, and the positioning hole is arranged between two adjacent fixed teeth;

[0011] The movable plate is arranged in the chute. The movable tooth is inserted into the positioning hole and can slide along the positioning hole to change the distance between the movable tooth and the adjacent fixed tooth.

[0012] Further, the movable plate extends towards the handle to have an operating portion, a control assembly is arranged on the handle, and the control assembly is connected to the operating portion.

[0013] Further, a positioning groove is arranged on the side surface of the fixed tooth facing the movable tooth, and the movable tooth is inserted into the positioning groove in the initial state.

[0014] Further, the number of the movable teeth is multiple, the movable teeth and the fixed teeth are alternately arranged in sequence. A positioning groove is arranged on one side of the fixed tooth facing the adjacent movable tooth, and the positioning grooves of all the fixed teeth are arranged on the same side of the corresponding fixed teeth. The movable teeth are inserted into the positioning grooves in the initial state.

[0015] Further, the ultra-thin straightening comb further includes a temperature detection mechanism. The temperature detection mechanism is arranged inside the heat-insulating housing, and the temperature detection mechanism is in contact with the heat-conducting mounting plate;

[0016] And / or, a negative ion mechanism is further arranged inside the comb body.

Detailed implementation manners

[0028] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment

[0030] As Figures 1 to 7 shown, this embodiment provides an ultra-thin straightening comb, including a comb body and a heating component 400. A plurality of comb teeth 200 arranged in a straight line in a row are provided on the comb body along its length direction, and at least some of the plurality of comb teeth 200 have heat conductivity. The heating component 400 is fixed on the comb body and is connected to the comb teeth 200 with heat conductivity to heat the comb teeth 200 with heat conductivity.

[0031] Wherein, the length direction of the comb body is also the direction in which a plurality of comb teeth 200 are arranged at intervals in sequence, which is also the left-right direction shown in Figure 1 and Figure 2 In this embodiment. The statement that "at least some of the plurality of comb teeth 200 have thermal conductivity" can be understood as that all of the plurality of comb teeth 200 have thermal conductivity or some of the plurality of comb teeth 200 have thermal conductivity. Among them, when some of the comb teeth 200 have thermal conductivity, preferably, a plurality of comb teeth 200 at a continuous position in a section in the arrangement direction of a row of teeth have thermal conductivity, that is, the comb teeth 200 at a local continuous position of a row of teeth have the function of straightening hair by heating. Generally speaking, when the ultra-thin hair straightening comb does not turn on the heating function of the heating component 400, it can be used as an ordinary comb. Therefore, to meet the requirement of quickly straightening hair, usually all of the plurality of comb teeth 200 of the ultra-thin hair straightening comb have thermal conductivity.

[0032] In this embodiment of the ultra-thin hair straightening comb, the comb teeth 200 with thermal conductivity can heat the hair under the action of the heating component 400 during the process of grooming the hair, so as to achieve the purpose of straightening the hair. The comb body of this embodiment of the ultra-thin hair straightening comb improves the user experience. Specifically, only one row of teeth is arranged along the length direction of the comb body of the ultra-thin hair straightening comb. Compared with the form of arranging multiple rows of comb teeth 200 in the prior art, the thickness of the comb body in the direction perpendicular to the length direction of the comb teeth 200 (this thickness is equivalent to the width in the multi-row arrangement direction of multiple rows of comb teeth 200 in the prior art, corresponding to the dimension in the direction perpendicular to the paper surface shown in Figure 1 or Figure 2 can be reduced. Even the thickness of the comb teeth 200 in this direction can be reduced as much as possible according to needs. Correspondingly, the comb body can be made as ultra-thin as possible. The comb body is equivalent to a thin plate, solving the problem of the heaviness of the hair straightening comb, having the advantage of being convenient to carry, and being light in weight during use. During the long-term use by the user, the wrists and arms are not likely to feel fatigued. At the same time, the contact range of the ultra-thin hair straightening comb in the hair length direction is reduced. Even if the user needs to straighten and care for a local short range in the hair length direction or short hair, the ultra-thin hair straightening comb can still move within the range to be cared for along the hair length direction, and there is no difficulty in operation. And because the ultra-thin hair straightening comb can move within the range to be cared for, the straightening effect within the range to be cared for can also be ensured.

[0033] In the embodiment, the comb body generally includes a handle 300 and a comb tooth part. Specifically, referring to Figure 1 or Figure 2 shown, the handle 300 is generally rectangular, and the comb tooth part generally has a rectangular outline as a whole. The handle 300 is fixedly connected to one end of the comb tooth part in the length direction (the left-right direction shown in Figure 1 and Figure 2 ). The thickness of the handle 300 and the comb tooth part (the dimension in the direction perpendicular to the paper surface shown in Figure 1 and Figure 2 ),Figure 2 A plurality of comb teeth 200 are arranged on the comb tooth portion along the length direction of the comb tooth portion, and a heating assembly 400 is arranged on the comb tooth portion and connected to the comb teeth 200 having thermal conductivity.

[0034] The comb teeth and the handle 300 may be integrally constructed or separately fixedly connected. It is understandable that the handle 300 and the comb teeth form a long, thin plate-shaped comb body. When using the ultra-thin hair straightening comb, the user holds the handle 300 for operation, which is convenient and comfortable. At the same time, since the comb teeth 200 and the heating component 400 are both arranged on the comb teeth, when the user holds the handle 300, the problem of hand burns due to the heat generated by the heating component 400 is avoided, thereby improving the comfort of the user when using the ultra-thin hair straightening comb.

[0035] It should be noted that the handle 300 is not limited to the one given in this embodiment. Figure 1 or Figure 2 In the form shown, for example, the handle 300 can also be connected in the width direction of the comb teeth portion, which is equivalent to the length direction of the comb teeth 200 ( Figure 1 and Figure 2 The comb tooth portion (in the up and down direction shown) is widened on the side away from the comb teeth 200 to form a handle 300.

[0036] The multiple comb teeth 200 of the ultra-thin hair straightening comb of this embodiment can be fixed in various ways. In a specific implementation, the multiple comb teeth 200 are all fixedly connected to the comb body, and preferably one end of the multiple comb teeth 200 is fixedly connected to the heat-conducting mounting plate 220, and the heat-conducting mounting plate 220 is fixed to the comb tooth portion and connected to the heating component 400 for heat transfer, thereby achieving a fixed connection between the comb teeth 200 and the comb tooth portion, and transferring the heat of the heating component 400 to the comb teeth 200 with heat-conducting performance through the heat transfer performance of the heat-conducting mounting plate 220. In this specific implementation, the multiple comb teeth 200 preferably have heat-conducting performance. Optionally, the heat-conducting mounting plate 220 is fastened to the comb tooth portion by screws 902 or screws.

[0037] like Figure 1As shown, in another specific implementation form, a part of multiple comb teeth 200 is fixedly connected to the comb body, and the other part is movably connected to the comb body. For the convenience of description, they are respectively defined as fixed teeth 210 and movable teeth 230. Among them, the number of fixed teeth 210 is usually multiple, and its fixing form is the same as the previous form, that is, multiple fixed teeth 210 are fixed on the heat-conducting mounting plate 220. The heat-conducting mounting plate 220 is fixedly connected to the comb tooth part, and the heat-conducting mounting plate 220 is connected to the heating component 400. The number of movable teeth 230 can be one or more. The movable teeth 230 are arranged between adjacent fixed teeth 210 and can move between its adjacent fixed teeth 210 to adjust the distance between the movable teeth 230 and its adjacent fixed teeth 210.

[0038] In this embodiment, the ultra-thin straightening comb mainly takes the example that the comb teeth 200 include fixed teeth 210 and movable teeth 230 for explanation. For this form, in this embodiment, the number of movable teeth 230 is multiple, and the fixed teeth 210 and the movable teeth 230 are arranged alternately; that is, multiple comb teeth 200 are arranged according to the rule of one fixed tooth 210, one movable tooth 230, one fixed tooth 210, one movable tooth 230... In order to facilitate driving multiple movable teeth 230 simultaneously, multiple movable teeth 230 are fixedly spaced on the same movable plate 240, and by driving the movable plate 240, multiple movable teeth 230 move synchronously relative to the fixed teeth 210.

[0039] It can be understood that the multiple comb teeth 200 of the ultra-thin straightening comb in this embodiment are divided into two types: movable teeth 230 and fixed teeth 210. The movable teeth 230 can move relative to the fixed teeth 210, so that the tooth pitch between the movable teeth 230 and the fixed teeth 210 can be adjusted as needed. In particular, when using the ultra-thin straightening comb for straightening hair care, by moving the movable teeth 230 towards their adjacent fixed teeth 210, the hair can be clamped between the movable teeth 230 and the fixed teeth 210, thereby improving the heat transfer efficiency. And because the hair can be clamped and pulled, the straightening hair care efficiency is improved and the straightening hair care effect is better.

[0040] Among them, the movable connection between the movable teeth 230 and the comb body (that is, the comb tooth part) can be that the movable teeth 230 are directly slidably connected to the comb tooth part. At this time, a guide groove can be provided on the comb tooth part, and the movable plate 240 can be slidably arranged in the guide groove. It can also be as Figure 3 or Figure 5 shown, the movable teeth 230 are indirectly slidably connected to the comb body (that is, the comb tooth part). Specifically, a sliding groove 221 is provided on the heat-conducting mounting plate 220, and the movable plate 240 is slidably arranged in the sliding groove 221 to be slidably connected to the comb tooth part through the sliding groove 221.

[0041] Among them, this embodiment mainly aims at Figure 3The installation form of the movable tooth 230 is described in detail, which has better advantages. This is because the movable tooth 230 usually also has heat conduction performance. The movable plate 240 and the movable tooth 230 can be made of the same material. A chute 221 is provided on the heat conduction mounting plate 220, and the movable plate 240 is slidably abutted in the chute 221, so that the heat conduction mounting plate 220 and the movable plate 240 have a large heat transfer area. The heat conduction mounting plate 220 can not only transfer heat to the movable plate 240 but also quickly transfer it to the movable plate 240, enabling the movable tooth 230 to be quickly heated and improving the heating efficiency of the comb teeth 200.

[0042] It should be noted that in the way of installing the movable plate 240 connected to the movable tooth 230 by providing the chute 221 on the heat conduction mounting plate 220, since the number of movable teeth 230 is multiple and the movable teeth 230 and the fixed teeth 210 are alternately arranged, usually the movable plate 240 and the movable tooth 230 are taken as a whole and assembled into the chute 221 from one side of the heat conduction mounting plate 220. This easily causes misalignment between the movable tooth 230 and the fixed tooth 210 in the thickness direction ( Figure 3 the left - right direction shown). To solve this problem, as Figure 3 or Figure 5 shown, the heat conduction mounting plate 220 of this embodiment includes an integrally - formed mounting portion 223. The mounting portion 223 is in the shape of a thin plate. The lower edge of the mounting portion 223 is bent towards one side to form an upward - opening chute 221. The fixed tooth 210 is mounted on the bottom wall of the chute 221, and a guide hole is provided on the bottom wall of the chute 221 between adjacent fixed teeth 210. That is, referring to Figure 5 , the chute 221 is provided on one side of the mounting portion 223. The mounting portion 223 forms one side wall of the chute 221. On one side of the mounting portion 223, there is another side wall (defined as the first side wall 222) disposed opposite at intervals. A bottom wall is connected between the first side wall 222 and the lower edge of the mounting portion 223. The bottom wall is connected to the fixed tooth 210, and a guide hole penetrating in the length direction of the fixed tooth 210 ( Figure 5 the up - down direction shown) is provided at the position between adjacent fixed teeth 210. When installing the movable tooth 230, the movable plate 240 and the movable tooth 230 are placed above the chute 221, and then each movable tooth 230 is aligned with the positioning hole 224 one by one and inserted into the positioning hole 224. At this time, the movable plate 240 abuts in the chute 221. It should be noted that since the movable tooth 230 needs to move relative to the fixed tooth 210 in the length direction of the comb body, the length of the positioning hole 224 in the length direction of the comb body is greater than the width of the movable tooth 230 in this direction.

[0043] It can be understood that in the above structural form of the heat-conducting mounting plate 220, the thickness of the fixing teeth 210 can be consistent with the thickness of the lower surface of the bottom wall of the sliding groove 221, and it is not affected by the thickness of the mounting portion 223. Even if the thickness of the mounting portion 223 is relatively thin, the strength of the fixing teeth 210 can be ensured. Moreover, the width of the first side wall 222 of the heat-conducting mounting plate 220 ( Figure 1 or Figure 2 the up-and-down direction shown) can be smaller than the width of the mounting portion 223, which further facilitates the assembly between the moving teeth 230 and the fixing teeth 210, and can form an installation space for other components on the side of the mounting portion 223 facing the first side wall 222, enabling reasonable arrangement of the components and reducing the overall thickness of the ultra-thin straightening comb.

[0044] In order to facilitate the user to use the adjustment or clamping function of the moving teeth 230 of the ultra-thin straightening comb during actual use, an operation portion 241 for controlling the movement of the moving plate 240 is provided on the moving plate 240 of this embodiment. The operation portion 241 extends towards the handle 300 side, and a control component 700 is provided on the handle 300. The control component 700 is connected to the operation portion 241 so that when the user holds the handle 300 with one hand, the control component 700 can be operated simultaneously, and then the operation portion 241 is pushed by the control component 700 to realize the movement of the moving plate 240 driving the moving teeth 230.

[0045] As an implementable cooperation form between the control component 700 and the operation portion 241, a first inclined surface 242 inclined relative to the length direction of the comb body is provided on the operation portion 241. The control component 700 includes a control block 710. The control block 710 abuts against the first inclined surface 242, and the control block 710 can move in a direction perpendicular to the length direction of the comb body to push the first inclined surface 242 to drive the moving plate 240 and the moving teeth 230 to move along the length direction of the comb body.

[0046] Specifically, in this embodiment, as shown in Figure 1 or Figure 2 , the first inclined surface 242 of the operation portion 241 is inclined gradually away from the comb tooth portion in the direction from the end where the moving teeth 230 are connected to the moving plate 240 (the root of the moving teeth 230) to the end where the moving teeth 230 are away from the moving plate 240 (the head of the moving teeth 230), that is, Figure 1 the direction from top to bottom. The control block 710 of the control component 700 is equivalent to a button. The control block 710 is arranged on the side of the first inclined surface 242 facing the comb tooth portion, and the control block 710 abuts against the first inclined surface 242. Pressing the control block 710 causes the control block 710 to move Figure 2 upward, and the first inclined surface 242 drives the moving teeth 230 to move to the right, thereby reducing the distance between the moving teeth 230 and the adjacent right fixing teeth 210 on the right side, and thus clamping the hair.

[0047] The reverse movement of the moving tooth 230 can be achieved in various forms, and it is preferably automatically reset after being pressed. This embodiment provides a specific form of automatic reset, such as Figure 1 or Figure 2 As shown, the control component 700 further includes a reset member 720. The reset member 720 is used to reset the control block 710 so that the moving plate 240 is reset to the initial position. Specifically, the reset member 720 should be able to reset the control block 710 and at the same time reset the moving plate 240. In this embodiment, the reset member 720 is disposed between the control block 710 and the moving plate 240. The reset member 720 includes an abutting plate 724, a positioning block, a first spring 725 and a second spring 726. The positioning block is fixedly connected to the handle and is generally arranged in a "cross" shape, including a first positioning plate 721, a positioning column 723 connected to one side of the first positioning plate 721, and a second positioning plate 722 connected to the other side of the first positioning plate 721. The abutting plate 724 is connected to the side of the moving plate 240 where the moving tooth 230 is provided and is close to the operation portion 241. The first positioning plate 721 is generally arranged parallel to the length direction of the fixed tooth 210 or the moving tooth 230. The positioning column 723 is disposed on the side of the first positioning plate 721 facing the moving tooth 230 and is disposed in the middle of the first positioning plate 721. The second positioning plate 722 is perpendicular to the first positioning plate 721 and is disposed in the middle of the first positioning plate 721. Both ends of the first spring 725 abut between the abutting plate 724 and the first positioning plate 721, and the first spring 725 is sleeved outside the positioning column 723; at this time, since the positioning column 723 is disposed in the middle of the first positioning plate 721, the plate surface of the first positioning plate 721 around the positioning column 723 can abut and limit the first spring 725. Both ends of the second spring 726 abut between the second positioning plate 722 and the control block 710. Since the second positioning plate 722 is located in the middle of the first positioning plate 721, the part of the first positioning plate 721 on the side close to the control block 710 can guide and position the second spring 726. When the pressing external force on the control block 710 is removed, under the action of the second spring 726 and the first spring 725, the control block 710 moves downward, and the moving tooth 230 moves leftward to reset.

[0048] As a preferred form, in this embodiment, when the moving tooth 230 abuts against the fixed tooth 210 on its left, the moving tooth 230 cannot move further, that is, when the moving tooth 230 is reset to abut against the left fixed tooth 210, it is the stable state of the moving tooth 230, which can be understood as the initial position of the moving tooth 230. The state is as Figure 2 shown. The fixed tooth 210 on the adjacent side of any moving tooth 230 ( Figure 2 the left fixed tooth 210) serves as the limiting member for the reset of the moving tooth 230 and serves as the initial position of the moving tooth 230. In the initial state, the moving tooth 230 only abuts against the fixed tooth 210 on the other adjacent side of it (Figure 2 There is a tooth gap for hair to pass through between the fixed teeth 210 on the right side of the middle, so that when combing hair, the hair being combed can be clamped by the moving tooth 230 and the fixed tooth 210 when the control block 710 is pressed.

[0049] It should be noted that the first inclined surface 242 can also be arranged on the side of the control block 710 facing the handle 300, and only the inclination direction of the first inclined surface 242 and the corresponding reset member 720 and the control block 710 need to be adjusted adaptively. At the same time, the moving tooth 230 can also move to the side away from the handle 300 when the control block 710 is pressed and reset to the side of the handle 300 during reset, and only adaptive adjustments need to be made during actual design. To facilitate the user to control the control block 710 with the thumb, the control block 710 is preferably arranged on the side of the handle 300 facing the comb teeth 200.

[0050] To improve the cooperation stability between the control block 710 and the first inclined surface 242, preferably, a second inclined surface that cooperates with the first inclined surface 242 is arranged on the control block 710. It can be understood that when the second inclined surface arranged on the control block 710 is in contact with the first inclined surface 242, the contact area between the control block 710 and the first inclined surface 242 is relatively large, thereby improving the cooperation stability between the control block 710 and the first inclined surface 242.

[0051] During the hair combing process, if there is a gap or unevenness between the moving tooth 230 and the fixed tooth 210 with which it abuts in the initial position, it will cause the hair to be caught in the gap, and further cause the hair to be broken and the scalp to be pulled painfully during the combing process. To solve this problem, as Figure 1 or Figure 5 shown, a positioning groove 211 is formed by inwardly recessing the side of the fixed tooth 210 where it abuts against the moving tooth 230 in the initial position, and the positioning grooves 211 of all the fixed teeth 210 are arranged on the same side of their corresponding fixed teeth 210. Specifically, the upper end of the side of the fixed tooth 210 where it abuts against the moving tooth 230 is inwardly recessed to form an L-shaped positioning groove 211, that is, the positioning groove 211 includes an integrally formed vertical side wall and a horizontal bottom wall, the horizontal bottom wall is at the head position of the fixed tooth 210, and the vertical side wall is consistent with the length extension direction of the fixed tooth 210. Among them, both the vertical side wall and the horizontal bottom wall are formed by the fixed tooth 210 itself. The head of the moving tooth 230 is shorter than the head of the fixed tooth 210 so that the moving tooth 230 can move into the positioning groove 211 of the fixed tooth 210. At the same time, the width of the moving tooth 230 ( Figure 1 the left-right direction shown) is the same as the width of the horizontal side wall of the positioning groove 211, so that when the moving tooth 230 moves to the positioning groove 211, the fixed tooth 210 and the moving tooth 230 cooperate to form a comb tooth 200 with a flat surface.

[0052] The comb teeth part of the ultra-thin straightening comb in this embodiment further includes a heat insulation housing 100, which has heat insulation performance. The heat conduction mounting plate 220 and the moving plate 240 are installed in the heat insulation housing 100. The fixed teeth 210 and the moving teeth 230 pass through the heat insulation housing 100 and are exposed on one side of the heat insulation housing 100. The handle 300 is fixedly connected to the heat insulation housing 100.

[0053] The heating component 400 of the ultra-thin straightening comb in this embodiment is preferably an electrothermal film 410. The electrothermal film 410 is laid on one side surface of the heat conduction mounting plate 220, and the other side surface of the heat conduction mounting plate 220 abuts against one inner wall of the heat insulation housing 100. Specifically, the electrothermal film 410 is arranged on the side of the heat conduction mounting plate 220 facing the sliding groove 221 and is located at one end of the first side wall 222 far from the fixed teeth 210. A pressing plate 901 is arranged on the side of the electrothermal film 410 far from the heat conduction mounting plate 220. The pressing plate 901 and the heat insulation housing 100 are fastened by fasteners such as screws 902 or bolts, so as to press and fix the electrothermal film 410 and the heat conduction mounting plate 220.

[0054] Among them, in order to facilitate the installation of components such as the fixed teeth 210 and the moving teeth 230 into the heat insulation housing 100, the heat insulation housing 100 in this embodiment can be a split structure, including a front shell 102, a rear shell 103, and an upper shell 101 connecting the front shell 102 and the rear shell 103. The front shell 102 and the rear shell 103 are arranged at intervals relatively, forming an installation space for the comb teeth part.

The temperature detection mechanism can be a conventional device for detecting temperature. Specifically, the temperature detection mechanism in this embodiment is a temperature sensor 420. As shown in Figure 3 , below the side of the heat conduction mounting plate 220 where the electrothermal film 410 is installed and above the first side wall 222, there is a reserved installation space. An installation groove 9011 is arranged on the pressing plate 901. The temperature sensor 420 is fixed in the installation groove 9011 and is pressed and fixed to the heat insulation housing 100 through the pressing plate 901.

[0056] Preferably, in order to intelligently control the heating of the ultra-thin straightening comb, the ultra-thin straightening comb further includes a control panel 500, and the control panel 500 is connected to the temperature sensor 420 and the control switch 411 of the electrothermal film 410. Specifically, the control panel 500 is a circuit board provided with a control program and belongs to a conventional controller. The control switch 411 of the electrothermal film 410 is arranged on the back of the handle 300, that is, on the side away from the comb teeth 200. An accessory cavity 310 is arranged on the side of the handle 300 close to the comb tooth part. The operation part 241 of the moving plate 240 and the reset part 720 are arranged in the accessory cavity 310. The control panel 500 is installed on the side of the operation part 241 away from the first inclined surface 242. The temperature feedback and control between the control panel 500, the temperature sensor 420 and the electrothermal film 410 can adopt existing similar conventional technologies. The control panel 500 can realize multi-gear control during the heating process of the electrothermal film 410, and the heating power of the electrothermal film 410 is different in different gears.

[0057] The ultra-thin straightening comb of this embodiment further includes a negative ion mechanism.

A cover body 322 is further arranged on the handle 300 corresponding to the side of the insertion port. The cover body 322 can limit the lithium battery in the receiving cavity, and the cover body 322 can be opened to replace the lithium battery.

[0059] It can be understood that after the energy supply mechanism 800 is set, the ultra-thin straightening comb can be used without being plugged in, so as to meet the user's need to use the comb body anytime and anywhere and improve the user experience. The form of arranging the energy supply mechanism 800 in the handle 300 does not occupy extra space and better meets the requirement of small occupied space.

[0060] The thickness of the ultra-thin straightening comb in this embodiment can be processed to not exceed 15 millimeters, that is, the thickness of the fixed teeth 210, the heat-insulating housing, and the handle 300 do not exceed 15 millimeters.
