Description

Perm core

This creation is about a perm core technology, especially a perm core that allows the perm core to be safer and faster when heated, more precise in temperature sensing, and faster and safer to create a perfect hairstyle.

Beauty is a human nature. No matter whether a man or a woman wants to look good, the hairstyle will affect the appearance of a person. If the hair is suitable for oneself, the appearance will definitely double the extra points and it will look younger. Type, let people have more confidence.

So every time I go to the hair salon to sort out my hair style every time, whether it is haircut or perm, it is a way to change the hair style. The hair style created by perm will be more changeable, and the effect on the appearance will be more obvious, so Many salon hairdressers will introduce more popular perm and corresponding perm machines to help create a more beautiful and stylish hair style.

The common perm core structure used in the perm machine is more commonly provided with a nickel wire, a ceramic heating piece or a heating film inside the core body, and the heating perm is directly performed. However, the conventional perm core has no temperature control device, and the temperature control through the nickel wire, the ceramic heater or the heat film is not easy and dangerous, and it is easier. Because the perm temperature is too hot, it is not self-aware, so it is not only easy to damage the hair quality, but also may cause dangerous situations such as burning of the perm core.

Therefore, how to create a perm core with NTC thermistor and temperature snap switch inside, which makes the temperature sensing more precise, avoids overheating of the perm core, improves the safety during perm, and makes the perm safer and faster. The ability to create a perfect curly hair style will be the active disclosure of this creation.

The purpose of this creation is to provide a perm core, which is mainly provided with a temperature control device, which can make the temperature sensing more precise, avoid the temperature overheating during perming, damage the perm hair and damage the perm core, make the perm more safe and fast, hairdressing The stylist can also create a more perfect curly hairstyle to enhance the practicality of the perm core.

In order to achieve the above purpose, the present invention provides a perm core comprising: a core body, a heat conducting ring wire and a temperature control device. The inside of the core body has an accommodating space; the heat conducting ring wire is disposed in the accommodating space, and the heat conducting ring wire forms a receiving portion; the temperature control device is disposed in the accommodating portion of the heat conducting ring wire, and the temperature control device has a circuit board a temperature snap switch disposed on the circuit board and an NTC thermistor, and one side of the temperature control device is provided with an ear plug.

In a preferred embodiment, the core body is provided with a wide-type thermochromic rubber band or a narrow-type thermochromic rubber band. The heat-conductive loop wire is composed of a nickel-chromium alloy wire wrapped around the surface of the inner core and then covered with a heat-resistant tape. The left and right sides of the circuit board of the temperature control device are connected to the left and right ends of the heat conducting ring wire, and are fixed to the left and right ends of the inner winding core through copper rivets. The temperature control device is provided with a positive pole, a negative pole and a signal point, and is connected with a positive pole The point, the negative pole and the signal point are electrically connected to the ear plug.

The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily appreciate other advantages and effects of the present invention from the disclosure herein.

The embodiments of the present invention are described below with reference to the drawings. It should be noted that the following drawings are simplified schematic diagrams, and only the basic concept of the creation is illustrated in a schematic manner, and only the structure related to the creation is illustrated in the drawings. Rather than drawing according to the number, shape and size of the components in actual implementation, the types, quantities and proportions of the components in actual implementation are not limited to the illustrations, and can be changed according to the actual design requirements.

First, please refer to FIG. 1 and FIG. 2, which is a perspective exploded view of a preferred embodiment of the present permanent wave core and a combined three-dimensional appearance. As shown in the figure, the present invention is a perm core 1, including A core body 11, a heat-conductive loop wire 12, and a temperature control device 13. The core body 11 has an accommodating space 110 therein; the heat-conducting wire 12 is disposed in the accommodating space 110, the heat-conducting wire 12 forms a receiving portion 120, and the heat-conducting wire 12 is surrounded by a nichrome wire. The surface is further covered with a heat-resistant adhesive tape; the temperature control device 13 is disposed in the accommodating portion 120 of the heat-conductive loop wire 12, and the temperature control device 13 has a circuit. The board 131 has a temperature jump switch 132 and an NTC thermistor 133 disposed on the circuit board 131. One side of the temperature control unit 13 is provided with an ear plug type plug 130.

In a preferred embodiment, the core body 11 is provided with a wide-format thermochromic rubber band 111 or a narrow-type thermochromic rubber band, a wide-type thermochromic rubber band 111 or a narrow-type thermochromic rubber band. When the temperature is preheated, the color changes from blue to transparent white, or from red to transparent white, making it easier for the user to see that the temperature has reached the preset value. Of course, the color change of the thermochromic rubber band 111 is not limited to the foregoing. In other different embodiments, the color change may be different. The temperature control device 13 is provided with a positive electrode, a negative electrode, and a signal point, and is connected to the positive electrode. The negative pole and the signal point are electrically connected to the ear plug 130, and the temperature sensing point is designed to be better and safer.

With the above configuration, the temperature control device 13 is first disposed in the accommodating portion 120 of the heat-conducting loop wire 12 and then disposed in the accommodating space 110 of the core body 11 to complete the overall assembly. In actual use, according to the usual perm curling step, a region of the hair to be boiled is wound on the core body 11 respectively, and then the ear insert plug 130 on the side of the temperature control device 13 is inserted into the external hair iron. On the (not shown), and then through the hair iron to heat, you can create a perfect curly hairstyle. Moreover, since the temperature control device 13 is provided inside the permanent waving core 1, the temperature can be accurately controlled, and the damage of the hair or the damage of the core body 11 caused by excessive heating can be avoided, and the safety during perming can be improved.
