Description

Technical Field

[0001] The utility model relates to a straightening comb, in particular to a negative ion straightening comb, belonging to the field of hair care products. Background Art

[0002] A comb is a tool for combing hair. Traditional combs can only straighten hair and have a single function. With the development of technology, the functions of combs have gradually increased, and the functions of combs have become more and more comprehensive, such as functions like massage, heating, and negative ions.

[0003] The straightening combs in the prior art generally include heating comb teeth (metal) and anti-scald comb teeth (made of plastic and other materials). After heating the heating comb teeth, sliding over the hair achieves the straightening effect. Some straightening combs are also provided with a negative ion generator to endow them with a negative ion function, so as to eliminate static electricity during the straightening process and care for the hair and scalp.

[0004] However, the existing negative ion straightening combs have the following disadvantages:

[0005] 1. The comb body only has a negative ion generator, resulting in the inability to effectively eliminate static electricity and cannot well care for the hair and scalp;

[0006] 2. The comb teeth are easy to clamp or entangle the hair, resulting in hair breakage;

[0007] 3. It is powered by an AC power supply and cannot be used in scenarios without a socket. Summary of the Invention

[0008] In view of this, the utility model provides a negative ion straightening comb to solve the above problems existing in the prior art.

[0009] The technical solution of the utility model to solve the above technical problems is as follows:

[0010] A negative ion straightening comb includes an upper shell and a lower shell. An installation groove is opened on the lower shell, and comb teeth are embedded in the installation groove. One end of the comb teeth extends away from the installation groove;

[0011] The upper shell and the lower shell are buckled to form a receiving cavity. A power supply, a circuit board, and a negative ion generator that are electrically connected to form a closed circuit are arranged in the receiving cavity. The closed circuit extends on the lower shell to form a key respectively embedded on the lower shell and a negative ion emitting head arranged in the direction of the comb teeth, and the closed circuit extends on the upper shell to form a conductive strip embedded on the upper shell;

[0012] The comb teeth include a plurality of tongue-shaped metal teeth and a plurality of plastic teeth. The side of the metal teeth arranged inside the lower shell is provided with a heating component connected to the closed circuit.

[0013] On the basis of the above technical solution, the utility model can also be improved as follows.

[0014] Further, the metal teeth are distributed in multiple rows and are symmetrically arranged left and right. Both side edges of the metal teeth are provided with positioning grooves. The plastic teeth include a first tooth surrounding the metal teeth and a second tooth sleeved outside the metal teeth. One side of the second tooth close to the installation groove has a cavity adapted to the contour of the metal tooth. The metal teeth are arranged in the cavity and the positioning grooves are in close fit with the inner wall of the second tooth. The outer edge of the second tooth is in a sharp streamline shape.

[0015] As a preferred solution, the depth of the positioning groove decreases gradually outward along the direction of the installation groove, and the two side surfaces of the metal teeth without the positioning grooves form a seamless arc surface with the outer side surface of the second tooth.

[0016] As a more preferred solution, the end of the first tooth and / or the second tooth is provided with a spherical or columnar protrusion.

[0017] Further, a heat insulation sleeve is sleeved on the side of the heating component away from the metal teeth.

[0018] Further, the closed circuit also extends on the lower shell to form a display screen embedded in the lower shell.

[0019] Further, the negative ion emitter is a cluster of conductive wires.

[0020] Further, the power supply is a rechargeable battery, and a charging socket is formed on the upper shell or the lower shell.

[0021] The beneficial effects of the present utility model are as follows:

[0022] The present utility model is provided with a conductive strip and a cluster of conductive wires electrically connected to the negative ion generator, thereby improving the emission effect of negative ions, preventing damage to hair and scalp caused by static electricity.

The arrangement of the conductive strip 11 can form a ground connection when the human body contacts the hair straightener, guiding the elimination of static electricity and avoiding damage to the hair and scalp caused by static electricity. Moreover, the strip shape setting can ensure that the hair straightener contacts the human body in any holding manner, and the contact effect is better than that of a point-like conductive structure.

[0031] The comb tooth 03 includes a number of tongue-shaped metal teeth 31 and a number of plastic teeth. The side of the metal tooth 31 arranged inside the lower shell 02 has a heating component connected to the closed circuit. The tongue-shaped metal teeth 31 are convenient for hair to be inserted and pass through, and have a large contact area with the hair, which can significantly improve the hair straightening efficiency.

The outer edge of the second tooth 33 is in a sharp streamline shape, which is convenient for the comb tooth 03 to be inserted between the hairs and effectively prevents scalding.

[0033] In another embodiment of the present utility model, the depth of the positioning groove decreases outward along the direction of the installation groove 21, and the two side surfaces of the metal teeth 31 without the positioning groove form a seamless arc surface with the outer side surface of the second teeth 33, avoiding hair being wound and clamped.

[0034] In another embodiment of the present utility model, the ends of the first teeth 32 and / or the second teeth 33 are provided with spherical or columnar protrusions 34, further avoiding damage to hair and scalp.

[0035] In another embodiment of the present utility model, a heat insulation sleeve 07 is sleeved on the side of the heating component away from the metal teeth 31, completely covering the heating component to prevent the heating component from making the straightening comb housing heat up, damaging the straightening comb and scalding the user.

[0036] In another embodiment of the present utility model, the closed circuit further extends on the lower shell 02 to form a display screen 08 embedded in the lower shell 02, facilitating the viewing of the working state and working temperature.

[0037] In another embodiment of the present utility model, the negative ion emission head 51 is a cluster of conductive wires, which can effectively improve the negative ion emission effect.
