Description

Electric Heat Hair-Roll Setting Machine}

The present invention relates to a hair roll and a hair permator device. In particular, the present invention relates to an electrothermal hair roll setter having a cylindrical hair roll chip, which is used in a permanent device.

Traditional electrothermal hair roll setters use PTC heating electrical resistance as a heating unit of hair roll setters. The PTC heating electrical resistance is small in size and does not easily mesh with the inner wall of the hair roll setter, so direct heat conduction is difficult. Heat was conducted with two semicircular opening type elastic metal pipes between the PTC heating electrical resistance and the inner wall of the hair roll setter. In the case of such an electrothermal hair roll setter, the weight is large. Customers who want a perm need to weigh several dozen electrothermal hair roll setters over their heads during the perm. Adding a little more weight to each hair roll setter puts a heavy burden on the customer. In addition, both of these electrothermal hair roll setters used the sealing plug to seal the heat transfer unit of the hair roll setter. Since the sealing plug is thin, deformation occurs when the operating temperature of the electrothermal hair roll setter is high, resulting in loss of the sealing effect. And the electrothermal hair roll setter in the cleaning process, the cleaning liquid penetrates into the hair roll setter, the heat transfer unit is damaged and failure occurs.

The technical problem to be solved by the present invention is to provide a heat transfer hair roll setter that is light in weight and excellent in sealing against the heat transfer unit.

In order to solve the technical problem, the technical solution used by the present invention is a kind of electrothermal hair roll setter. It includes a cylindrical hair roll chip and a cylindrical inner tube fitted to the inner hole of the hair roll chip. There is a heat transfer layer between the hair roll chip and the inner tube. There is a conductor in the heat transfer layer, which passes through the hair roll chip and the inner tube and is connected to an external power source. There is a sealing structure between the holes in the hair roll chips on both sides. A seal is formed between the conductor described and the penetrating hair roll chip and the inner tube.

In the electrothermal hair roll setter, the sealing structure is made as possible as ultrasonic welding.

In the electrothermal hair roll setter, the sealing structure may be an adhesive structure.

In the electrothermal hair roll setter, the sealing structure may be a sealing ring type sealing structure.

In the heat transfer hair roll setter, the heat transfer layer may be a heat transfer film attached to the inner tube outer wall.

In the electrothermal hair roll setter, the heat transfer layer may also be a metal heating film.

In the heat transfer hair roll setter, the heat transfer layer may be a heating wire layer wound around the inner tube outer wall.

In the electrothermal hair roll setter, the conductor forms a touch portion on the outside of the hair roll chip and the inner tube as much as possible.

The present invention is structurally supported between the cylindrical hair roll chip and the cylindrical inner tube inserted into the inner hole of the hair roll chip, and is not easily damaged by external force. Both can be made very thin, and the overall weight is light. A stepped heat transfer unit is used between the hair roll chip and the inner tube. The stepped heat transfer unit is not only light in weight, but also has a large heat generation area and excellent heat generation effect as compared with PTC heat generation electric resistance. And since the gap between the inner wall of the hair roll chip can be made very small and even direct contact is possible, no separate metal heat conduction unit is required. Thus, the present invention can reduce the weight compared to the conventional electrothermal hair roll setter. There is also a sealing structure between both sides of the inner tube and the hole inside the hair roll chip. The contact surface axial length of the sealing structure between the cylindrical inner tube and the inner hole of the hair roll chip can be lengthened. The structure is stable and does not easily deform even at high temperatures and does not lose its effect. Thus, the present invention has a very good sealing effect for the heat transfer unit.

The present invention can increase the sealing effect of the heat transfer unit when using the sealing structure of the ultrasonic welding.

Hereinafter, embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

Inventive electrothermal hair roll setter

[Example 1] is as shown in FIG. The electrothermal hair roll setter includes a cylindrical hair roll setter chip 1 and a cylindrical inner tube 2 fitted into an inner hole of the hair roll setter chip. A cylindrical metal heating film 3 is formed between the hair roll setter chip and the inner tube. The metal heat generating film 3 is connected to the metal touch 4 which is fitted to one side of the inner hole through the metal guide line 6. The inner hole on one side of the inner tube 2 and the metal touch 4 form the power socket of the electrothermal hair roll setter. There is an adhesive layer 5 between both of the inner tube 2 and the inner hole of the hair roll setter chip 1 to form a seal between both of the inner tube 2 and the inner hole of the hair roll setter chip 1. When the metal guide wire 6 and the metal touch 4 are injection molded into the inner tube 2, they are interrupted. Thus, an excellent seal is formed with the inner tube 2.

[Example 2] is as shown in FIG. It includes a cylindrical hair roll chip 1 and a cylindrical inner tube 2 inserted into the inner hole of the hair roll chip. There is a heating wire layer 11 wound on the outer wall of the inner tube between the hair roll chip and the inner tube. Both sides of the heating line layer 11 extend from one side of the inner tube 2 through the metal guide line 8 wrapped with copper chips. The metal guide line 8 wrapped with copper chips is interrupted when casting in the inner tube 2 to form an excellent seal with the inner tube 2. There is an elastic sealing plastic ring 7 between both the inner tube 2 and the inner hole of the hair roll chip 1, thereby making a seal between both the inner tube 2 and the inner hole of the hair roll chip 1.

In Example 3, the electrothermal hair roll setter includes a cylindrical hair roll chip 1 and a cylindrical inner tube 2 fitted in the inner hole of the hair roll chip. The heat-transfer film 9 is attached to the outer wall of the middle portion of the inner tube 2, and the heat-transfer film 9 is connected to the outside through a hard metal spiral 10. The metal spiral 10 extends from one side of the electrothermal hair roll setter through the coupling surface between the inner tube 2 and the hair roll chip 1, and forms a power socket of the electrothermal hair roll setter. A sealing structure is formed by ultrasonic welding between both sides of the inner tube 2 and the inner hole of the hair roll chip 1.

The inventive electrothermal hair roll setter structurally supports each other between the cylindrical hair roll chip and the cylindrical inner tube fitted in the inner hole of the hair roll chip. Especially in the case of adhesion or ultrasonic welding, the hair roll chip and the inner tube form an integral body on both sides. It is not easily damaged under the influence of external force. Both can be made very thin, and the overall weight is rather light. A stepped heat transfer unit is used between the hair roll chip and the inner tube. In the case of the stepped heat transfer unit, in particular, the heat transfer film and the metal heat transfer film are light in weight, have a large heat generation area, and have a good heat generation effect, compared with the PTC heat generation electrical resistance. And the gap between the inner wall of the hair roll chip can be made very small and even direct contact is possible. So no separate metal heat conduction unit is needed. Thus, this utility model has significantly reduced weight compared to the conventional electrothermal hair roll setter.

In addition, both sides of the inner tube form a sealing structure between the holes of the hair roll chip. The sealing structure contact surface axial length between the cylindrical inner tube and the inner hole of the hair roll chip can be rather long, and is structurally stable, so that it is not easily deformed even at high temperatures. Especially in the case of adhesion or ultrasonic welding, sealing is more excellent. This utility model is excellent in sealing against a heat transfer unit in a light weight situation. The utility model electrothermal hair roll setter can be washed with a washing liquid, and can be used after washing and drying. The cleaning liquid penetrates into the hair roll setter and does not damage the heat transfer unit and cause breakdown.
