[0002] The electric heating hair straightening comb is a hair straightening tool different from the existing pliers-type hair straighteners. It has a comb shape and can use electric heating to straighten the hair during the hair combing process. It is very convenient to use. The structural principle is to use metal materials to make comb teeth and use ceramic heating elements to transfer temperature to the metal comb teeth. When combing hair, the hair passes through the metal comb teeth to be heated and the hair is straightened under the corresponding combing tension. The existing method often directly heats the heat-conducting comb teeth and then acts on the hair. The comb teeth heating temperature of this method is relatively high, and it is easy to burn the hair or damage the scalp when directly acting on the hair; another method is to install plastic comb teeth outside the heat-conducting comb teeth, and the heat of the plastic comb teeth acts on the hair. This method is prone to waste of heat energy, and the plastic comb teeth are prone to burn after long-term use.

By setting a switch on the main body, when in use, the heating component can be directly powered by an external AC power supply connected to the charging interface, or it can be powered by a battery, which can be portable, plug-and-play, and charge-while-use, meeting the user's needs. At the same time, the switch can be controlled by the control chip to switch the series-parallel relationship between the first heating element and the second heating element, which can adapt to different power supply modes and achieve high efficiency and low loss. This patent directly acts on the hair through the heated comb teeth, which has high heat and is prone to hair burning. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0033] A preferred embodiment of the utility model is a hair straightening comb that can efficiently dry hair and visualize the amount of electricity; Figure 1 , Figure 3 and Figure 5As shown, the housing 1 is composed of an upper housing 100 and a lower housing 2 which are detachably connected and fixed, and the housing is divided into two parts, one part is used to fix the comb tooth assembly 2 in a comb tooth assembly fixing cavity 102, and the other part is used to hold a handle 103. The comb tooth assembly 2 is fixed in the comb tooth assembly fixing cavity, and a heating component 3 is also arranged in the comb tooth assembly fixing cavity 102. The heating component is located below the comb tooth assembly so as to heat the comb teeth. A control panel 5 and a battery 4 for powering the control panel are arranged in the handle 103. The control panel is connected to the heating component and controls and adjusts the heating intensity of the heating component. A control button 8 connected to the control panel is also arranged on the outer surface of the handle. The control button 8 includes a switch button 80 for starting or closing the straight hair comb, and a gear adjustment button 81 for adjusting the control panel to change the working mode of the heating component. A charging port 6 for charging the battery is provided at the end of the handle, and a display screen 10 for displaying the battery power is provided inside the handle. A lens 9 is also provided on the handle for convenient viewing of the appearance through the mirror. It should be noted that the mirror can be set on any side of the handle, and a hollow window is provided on the handle corresponding to the display screen to facilitate the display screen to display the power.

[0034] Specifically, Figure 2-5 and Figure 11-Figure 12 As shown, the comb tooth assembly 2 includes a nylon comb tooth assembly 20 and an aluminum alloy comb tooth assembly 21 inserted into the nylon comb tooth assembly. The aluminum alloy comb tooth assembly 21 includes an aluminum alloy comb tooth bottom plate 210 and an aluminum alloy comb tooth assembly fixing ear 211 protruding from the aluminum alloy comb tooth bottom plate, and the aluminum alloy comb tooth assembly is fixed in the nylon comb tooth assembly 20 through the aluminum alloy comb tooth assembly fixing ear. The aluminum alloy comb tooth assembly 21 also includes an aluminum alloy comb tooth 212 arranged above the aluminum alloy comb tooth bottom plate. The nylon comb tooth assembly 20 includes a nylon comb tooth bottom plate 202 and nylon comb teeth 200 and 201 arranged on the nylon comb tooth bottom plate. The nylon comb teeth are arranged in a hollow shape, and a nylon comb tooth hollow cavity 2003 is arranged therein. The aluminum alloy comb tooth assembly is inserted into the nylon comb tooth hollow cavity 2003 through the aluminum alloy comb tooth 212 inserted into the nylon comb tooth bottom plate to complete the fixing of the nylon comb tooth assembly and the aluminum alloy comb tooth assembly.

[0035] Furthermore, if Figure 2As shown in FIG. 10 , the nylon comb teeth are divided into outer nylon comb teeth 200 and inner nylon comb teeth 201. The outer nylon comb teeth are arranged around the inner nylon comb teeth. Hollow surfaces 2002 are arranged on both sides of the inner nylon comb teeth 201. The aluminum alloy comb teeth 212 are provided with heating arc surfaces 2120 corresponding to the hollow surfaces. When the aluminum alloy comb tooth assembly is fixed in the nylon comb tooth assembly, the heating arc surface is just located at the hollow surface, so that the heating arc surface contacts the hair for drying. It should be noted that the aluminum alloy comb teeth do not need to be inserted into the outer nylon comb teeth, that is, the outer nylon comb teeth do not need to be provided with hollow surfaces, and they can be set at room temperature. They can be set to be solid or hollow, so as to avoid accidental contact with the outer nylon comb teeth when using a straight hair comb and cause injury, and to avoid contact between other objects and the outer nylon comb teeth, which is safer.

[0036] Furthermore, if Figure 2 , Figure 8 , Fig.10 and Fig.12 As shown, a concave limiting groove 2121 is provided between the two groups of heating arc surfaces 2120, and a limiting column 2004 is provided in the hollow cavity of the nylon comb teeth corresponding to the limiting groove, so as to limit the aluminum alloy comb teeth in the horizontal direction to prevent the aluminum alloy comb teeth from shaking left and right, and also to prevent the shaking left and right to cause a gap between the heating arc surface and the hollow surface, thereby causing the hair to be stuck. The nylon comb teeth 200 and 201 are provided with a solid tip 2000, and a cavity for accommodating the aluminum alloy comb tooth tip 2122 is provided in the solid tip, and a gap 2001 is left between the upper end of the cavity and the upper end of the aluminum alloy comb tooth tip, so as to prevent the heat of the aluminum alloy comb teeth from being transferred to the solid tip through the aluminum alloy comb tooth tip, thereby avoiding damage to the scalp. At the same time, the gap also allows the nylon comb teeth to have a certain movable distance, so that the solid tip has a certain movement buffer when contacting the scalp to avoid damage to the scalp.

[0037] Furthermore, if Fig.10 and Fig.12 As shown, the outermost nylon comb tooth hollow cavity of the internal nylon comb teeth 201 is provided with a step 2005. Due to the setting of the step, the upper surface of the aluminum alloy comb tooth bottom plate and the lower surface of the nylon comb tooth bottom plate are only in contact at the periphery, while the middle part is hollowed out. When the straight hair comb is used, the middle comb teeth can be moved in the hollowed-out cavity under force, avoiding the force of the comb teeth from acting completely on the scalp, and a certain degree of force release is performed through the hollowed-out cavity, which has a better effect and better protection for the scalp. In order to make it more convenient to dry hair, the internal nylon comb teeth are arranged symmetrically on the left and right as a whole, and the height of the middle part is successively reduced along the two ends, so that the nylon comb teeth can realize the connection of the tip to form a virtual arc surface, thereby improving the hair drying effect. In order to further facilitate the hair combing effect, the solid tip adopts a flat elliptical shape, which has a better hair combing effect.

[0038] Furthermore, if Figure 3As shown, a heating component connection cavity 22 is provided under the bottom plate of the nylon comb tooth assembly, and the heating component 3 includes a heating plate 30, which conducts heat to the aluminum alloy comb teeth through heating of the heating plate, thereby heating the aluminum alloy comb teeth. And a heat insulation cover 33 is provided under the heating plate, and the heat insulation cover is fixed under the nylon comb tooth assembly, so that the heating plate is fixed in the heating component connection cavity, and a mica heat insulation sheet 31 is provided under the heating plate to prevent heat loss, so that the heat is more concentratedly conducted to the aluminum alloy comb teeth, and the mica heat insulation sheet is fixed under the bottom plate of the nylon comb tooth assembly through a stainless steel pressing plate 32 to reduce the distance between the heating plate and the nylon comb teeth, accelerate the heat transfer, and reduce the heat loss. At the same time, the double-layer insulation effect of the mica heat insulation sheet and the heat insulation cover also prevents the lower surface of the lower shell from being heated.

[0039] Furthermore, if Figure 3-4 As shown, a negative ion device 7 is also provided in the handle 103, and the negative ion device is arranged close to the heating component 3. An air guide port 330 is provided on the side of the heat insulation cover 33 close to the negative ions. When the negative ions are working, the negative ions enter the heating component connecting cavity 22 through the air guide port, and flow out through the gap between the nylon comb teeth and the aluminum alloy comb teeth to act on the hair, thereby maintaining the hair and avoiding the occurrence of frizzy hair and the like.

[0040] It should be noted that in the present invention, the aluminum alloy comb teeth can be replaced with comb teeth made of other heat-conducting materials, that is, the heat of the heating plate can be transferred to the heating arc surface for heating. The nylon comb teeth can be replaced with heat-insulating comb teeth such as plastic comb teeth, that is, the heat cannot be transferred to the insulating comb teeth, thereby achieving a heat-insulating effect. The negative ion device can also be replaced with other disinfection devices to disinfect and sterilize the scalp and hair, etc., which should all fall within the protection scope of the present invention.

[0041] A preferred embodiment 2 of the utility model is a hair straightening comb that dries hair efficiently and has visible power consumption. The difference from the embodiment 1 is that a vibration component device (not shown in the figure) can also be arranged in the heating component connection cavity, which vibrates when combing the hair to maintain the scalp, with better effect.

[0042] It should be understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
