Perm lot containing film heater {A perm lot containing film heater}

The present invention relates to a rod for permer with a built-in film heater, and more particularly, by incorporating a film heater in the inside of the rod, the structure is simple, light weight, good manufacturing and assembly, one side of the +, A pair of contact terminals are soldered or ultrasonically fused with wires and connected to the terminals of the film heater, and around the contact terminals are fixed with hexagon nuts, and the plugs of the power jacks opposite the hexagon nuts are connected to the Easy to connect In addition, by incorporating a bimetal and a temperature sensor, it is possible to prevent the rod from overheating, and since the rod is used at a temperature of 100 to 150 ° C, the temperature can be controlled so as not to rise to the maximum temperature, thereby improving the efficiency of the perm. It relates to a rod for permer with a built-in film heater.

In general, the perm rod is an essential perm device that is used to give a wave of hair when perm, until now a variety of proposals have been widely used. Among them, the rod structure most commonly used has a cylindrical body and a plurality of protrusions formed at both ends of the body to hang rubber bands in the circumferential direction. When using this, the bundle of hair was wrapped around the outer periphery of the cylindrical body with a perm or cloth, and then wound to the required length, and the perm was used with the perm solution while the hair was fixed with rubber bands using both protrusions of the rod. However, the general rod structure used in this way has a disadvantage in that it takes a very long time because it only has a function of winding the hair, and the wave is not even and there is a problem in that it is difficult to produce a variety of waves.

On the other hand, in recent years, a configuration has been proposed to shorten the perm time and produce various waves by providing a PTC heater or a silicone heating wire that generates heat by supplying power to the rod at the same time, so that the permaper and the dry can be simultaneously produced. .

Examples of the above can be seen in FIG. 1, which is an exploded perspective view showing the overall configuration of a conventional permanent battery heater-loaded PTC heater, and FIG. 2, which is a front sectional view of the permanent heater-loaded PTC heater. The permanent rod 100 is a cylindrical body 10 having an overall appearance, a support member 20 inserted into and fastened to the inside of the body 10, and fixed to the support member 20 and heated by a heater. The upper and lower heat plates 30 are configured. The body 10 is formed in a cylindrical shape in which one side is opened, and protrusions 11 are formed along the circumferential direction, respectively, on both sides of the rubber band, and the rod 100 is placed on a perm not shown at the center of one side. A ring 12 for fixing is formed. The support member 20 is inserted into the body 10 and is fixed. At one end thereof, an insertion groove 21 into which a separate plug connected to a perm and an electric wire is formed is formed, and the other side is formed in a plate shape. The support surface 22 which consists of is formed integrally. A pair of contact terminals 23 are inserted into the insertion groove 21 to maintain a state of protruding side by side into the insert, thereby inserting the plug connected to the perm into the insertion groove 21 to contact the plug and the contact. As the terminal 23 is connected, power is supplied from the perm. In addition, a square fastening hole 24 is drilled in a pair on the support surface 22 of the support member 20, and a separate rectangular heater 25 is inserted into and fastened to the fastening hole 24. The heater 25 may be fastened to both side fastening holes 24 depending on the purpose of use of the rod, or may be used by selectively fastening only one.

In addition, hot plates 30 and 30a are fastened to upper and lower portions of the support surface 22, respectively.

The hot plates 30 and 30a are formed in the same structure and fastened symmetrically to each other, that is, the metal pieces having good thermal conductivity are bent in a semicircle to be tightly fastened to the support surfaces 22, respectively. That is, the fastening piece 31 is formed in which the hot plates 30 and 30a are bent at one side end thereof, and is coupled to the contact terminal 23 as a separate bolt 32 to be energized. At this time, a slightly protruding surface 33 is formed on the contact surface of the hot plate 30, 30a to be in intimate contact with the heater 25 fastened to the fastening hole 24 of the support surface 22. However, the conventional rod as described above has a problem in that its configuration is complicated, its number of parts, its manufacture and assembly are not good, and the reliability of the product is deteriorated since the contacts are not good and the temperature cannot be controlled due to the supply of power.

The present invention was created in order to solve the above problems, and by incorporating a film heater inside the rod, its configuration is simple and lightweight, and manufacturing and assembling is good, and a pair of + and-contact terminals on one side Film is soldered or ultrasonically fused with wires and connected to the terminals of the film heater, and the-contact terminal is fixed with a hexagonal nut, and the plug of the power jack on the opposite side of the hexagonal nut is easily connected to the permator. It is an object of the present invention to provide a rod for permer with a heater.

Another object is to incorporate a bimetal and a temperature sensor, to prevent the rod from overheating, and because the rod is used at a temperature of 100 to 150 ℃, it is possible to control the temperature so as not to rise to the maximum temperature, perma time It is to provide a permanent rod for film that has a built-in film heater that can shorten and produce various waves to improve the efficiency of the perm.
