Description

Technical Field

[0001] The utility model relates to a comb, in particular to a comb which can straighten hair. Background Art

[0002] A hair straightening comb is a hair straightening device that uses high temperature to straighten hair. It conducts temperature to the surface of a heat conducting plate through a heating element, and then clamps the hair between the heat conducting plate and the clamping plate to straighten the hair. In order to prevent the teeth of existing hair straightening combs from contacting the scalp or skin of a person, a protective ring is provided around the teeth, which greatly affects the hair straightening effect and is also very easy to clamp the hair.

[0003] Patent number CN202022327292.3 is a hair straightening comb patent, and its technical features are: a hair straightening comb, including a first shell, a second shell detachably fixed to the rear side of the first shell, a control component arranged between the first shell and the second shell, and a heating component arranged on the front side of the first shell, characterized in that the heating component includes a heat insulation block, an electric heating plate, a heat conductive block, a positioning frame and a protective ring; a sink cavity is formed on the front side of the first shell; the heat insulation block is embedded and fixed at the bottom of the sink cavity, a grid portion is formed outwardly on the front side of the heat insulation block, the electric heating plate is attached to the front side of the grid portion, and the The heat-conducting block is attached to the front side of the electric heating plate, the positioning frame is sleeved outside the heat-conducting block and is detachably fixed on the heat-insulating block and arranged in the sink cavity, and the protective ring is detachably fixed at the opening of the sink cavity; a plurality of tongue plates are formed outwardly on the front side of the heat-conducting block, and correspondingly, a plurality of protective rings are formed outwardly on the front side of the protective ring, and the number and positions of the protective rings are matched with the number and positions of the tongue plates, and an end plate is formed outwardly at the upper and lower ends of the front side of the protective ring, the top and bottom tongue plates are respectively arranged on the inner sides of the two end plates, and the remaining plurality of tongue plates are respectively inserted into the plurality of protective rings. We can clearly see from the above patent that the heat conducting plate needs to be protected by a protective ring so as not to burn the user. However, this structure has the following defects: 1. When straightening hair, the hair is easily isolated by the protective ring, so that the hair cannot make good contact with the heat conducting plate, and the straightening effect is poor; 2. The manufacturing process is cumbersome and the cost is high; 3. It is easy to clamp the hair. Since there is a gap between the protective ring and the heat conducting block, the hair can easily enter the above gap and be clamped. Summary of the invention

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a novel hair straightening comb which has good hair straightening effect, low cost and will not cause hair clipping.

[0005] To achieve the above object, the utility model adopts the following technical scheme: a hair straightening comb, comprising a shell, a circuit device, a heating element and a comb body made of a heat-conducting element, characterized in that: the comb body is provided with a mounting portion for mounting the heating element, a row of heat-conducting comb teeth are provided on the comb body, the surface between adjacent heat-conducting comb teeth is a hair straightening working surface, the outer peripheral surface of the heat-conducting comb teeth is a guide surface, the guide surface is composed of two side surfaces and a top surface, an anti-scalding layer is injection-molded on the guide surface of the heat-conducting comb teeth, the working surface of the heat-conducting comb teeth is exposed, the shell is provided with a notch, and the heat-conducting comb teeth are exposed from the notch to form a hair straightening portion.

[0006] By adopting the above scheme, a good straight hair effect can be easily achieved, wherein an anti-scalding layer is injection-molded on the guide surface, so that a seamless connection is achieved between the anti-scalding layer and the guide surface, making the entire comb teeth flexible, and there is no gap between the comb teeth and the anti-scalding layer, so hair clamping will not occur.

[0007] The utility model is further configured as follows: the side surface and the top surface of the guide surface are both provided with convex points or grooves, and the anti-scalding layer is fixedly connected with the side surface and the top surface of the guide surface by means of the convex points or grooves.

[0008] By adopting the above solution, the anti-scalding layer can be well fixed on the guide surface. Specifically, since the comb tooth body is usually made of metal material, and the anti-scalding layer is made of plastic material, the expansion coefficients of the two are different when heated, so the protrusions or grooves are used to pull and achieve a fixed connection between the two.

[0009] A further configuration of the utility model is that: a spherical convex point is arranged on the outer side of the top surface of the guide surface (52) and on the anti-scalding layer, an inverted trapezoidal notch is arranged on the top surface of the guide surface, the bottom surface of the inverted trapezoidal notch is arranged as a rough surface or a stress point, and the anti-scalding layer is injection-molded into the inverted trapezoidal notch to achieve a fixed connection between the two.

[0010] By adopting the above solution, the spherical convex points increase the massage function of the comb teeth when combing the hair, thereby increasing the experience; in addition, the setting of the inverted trapezoidal notch can well ensure that the top of the anti-scalding layer is tightly connected with the top of the comb teeth.

[0011] The last configuration of the utility model is that the mounting portion is a long through hole arranged on one side of the comb body.

[0012] With the above solution, no matter whether an inverted trapezoidal notch or a convex point or a concave groove is used, the top fixed connection is achieved by using a through hole, which is to facilitate the installation of the heating element.

[0013] The utility model is further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0025] like Figures 1-4 As shown, a hair straightening comb comprises a shell 1, a circuit device 2, a heating element 3 and a comb body 4 made of a heat-conducting element, wherein the comb body 4 is provided with a mounting portion 41 for mounting the heating element 3, and the comb body 4 is provided with a row of heat-conducting comb teeth 5, the surface between adjacent heat-conducting comb teeth 5 is a hair straightening working surface 51, the outer peripheral surface of the heat-conducting comb teeth 5 is a guide surface 52, and the guide surface 52 is composed of two side surfaces and a top surface, and an anti-scalding layer 53 is injection-molded on the guide surface 52 of the heat-conducting comb teeth 5, and the working surface of the heat-conducting comb teeth 5 is exposed to the outside, and a notch 6 is provided on the shell 1, and the heat-conducting comb teeth 5 are exposed from the notch 6 to form a hair straightening portion 56, which can conveniently achieve a good hair straightening effect, wherein the anti-scalding layer 53 is injection-molded on the guide surface 52, so that the anti-scalding layer 53 and the guide surface 52 are seamlessly connected, so that the entire heat-conducting comb teeth 5 are flexible, and in addition There is no gap between the heat-conducting comb teeth 5 and the anti-scalding layer 53, and hair clamping will not occur. The side and top surfaces of the guide surface 52 are provided with protrusions or grooves, and the anti-scalding layer 53 relies on the protrusions or grooves to achieve fixed connection with the side and top surfaces of the guide surface 52, so that the anti-scalding layer 53 can be well fixed on the guide surface 52. Specifically, since the comb tooth body 4 is usually made of metal material, and the anti-scalding layer 53 is made of plastic material, the expansion coefficients between the two are different when heated, so the protrusions or grooves are used to pull them to achieve a fixed connection between the two. The outer side of the anti-scalding layer 53 and the top surface of the guide surface 52 is an arc or a plane. When it is an arc, it is gentler on the scalp and can also massage the scalp. The mounting portion 41 is a long through hole arranged on one side of the comb tooth body 4, and the heating element 3 is installed through the long through hole to guide the heat to the comb tooth body 4. Example

[0026] like Figure 3 , Figures 5-7A straightening comb as shown includes a housing 1, a circuit device 2, a heating element 3, and a comb tooth body 4 made of a heat-conducting member. An installation portion 41 for installing the heating element 3 is provided on the comb tooth body 4. A row of heat-conducting comb teeth 5 is provided on the comb tooth body 4. The surface between adjacent heat-conducting comb teeth 5 is a straightening working surface 51, and the outer peripheral surface of the heat-conducting comb tooth 5 is a guiding surface 52. The guiding surface 52 is composed of two side surfaces and a top surface. An anti-scald layer 53 is injection-molded on the guiding surface 52 of the heat-conducting comb tooth 5. The working surface of the heat-conducting comb tooth 5 is exposed. A notch 6 is provided on the housing 1, and the heat-conducting comb teeth 5 project out from the notch 6 to form a straightening portion 56, which can easily achieve a good straightening effect. Among them, by injection-molding the anti-scald layer 53 on the guiding surface 52, seamless connection is achieved between the anti-scald layer 53 and the guiding surface 52, making the entire heat-conducting comb tooth 5 flexible. In addition, there is no gap between the heat-conducting comb tooth 5 and the anti-scald layer 53, and hair clamping will not occur. A convex point or a groove is provided on the side surface of the guiding surface 52, and the anti-scald layer 53 is fixed and connected to the side surface of the guiding surface 52 by relying on the convex point or the groove. In this way, the anti-scald layer 53 can be well-fixed on the guiding surface 52. Specifically, since the comb tooth body 4 is usually made of a metal material and the anti-scald layer 53 is made of a plastic material, the expansion coefficients of the two are different during heating. Therefore, the two are fixedly connected by pulling through the convex point or the groove. A spherical convex point 54 is provided on the anti-scald layer 53 and on the outside of the top surface of the guiding surface 52. An inverted trapezoidal notch 54 is provided on the top surface of the guiding surface 52. The bottom surface of the inverted trapezoidal notch 55 is set as a rough surface or a stress point. The anti-scald layer 53 is injection-molded into the inverted trapezoidal notch 55 to achieve the fixed connection between the two. Among them, the spherical convex point 54 has a massage function when combing the hair, increasing the experience. In addition, the setting of the inverted trapezoidal notch 55 can well ensure that the top end of the anti-scald layer 53 is tightly connected to the top end of the heat-conducting comb tooth 5. The installation portion 41 is a long through-hole provided on one side of the comb tooth body 4. The heating element 3 is installed through the long through-hole to guide heat to the comb tooth body 4.
