Hair curler, hair perm device using the same, and hair perm treatment method using the same

technical field

The present invention relates to a hair curler used for hair perm treatment, a hair perm device using the hair curler and a hair perm treatment method using the device.

Background technique

As a conventional hair perm device, for example, there is a hair perm device described in Japanese Patent No. 3798374. This device is detachably connected with a curling clip on the other end of the cord drawn from the suspended power distribution box, and , has a roll-in tube, the roll-in tube is connected with the hair curler on the cord, the sling can be brought in and out from the aforementioned power distribution box, the sling can hang down the hair curler to any position, and the hair curler, A ceramic heater is connected to the terminal of the detachable pin socket via a wire. In addition, two support rods are planted on the main body of the pin socket to clamp the ceramic heater, and the support rods A nut is fixed at the front end, and a ceramic tube is externally embedded on the reduced-diameter stepped part formed on the main body of the pin socket, and a cover body with a central hole is covered on the opening of the other end of the ceramic tube. A threaded piece with a press seat and a hook is passed through the central hole of the cover body, and is screwed with the aforementioned nut to be uniformly fixed.

The hair perm device is arranged above the head of the person to be permed, and a plurality of hair curlers are arranged on the hair of the person to be permed, and the plurality of hair curlers are connected to a cord extending in a manner suspended from the power distribution box.

However, in the above-mentioned hair curler device, since the ceramic tube is used in the hair curler, the weight is relatively large. In order to reduce the weight, it is necessary to hang the hair curler by a rope hung on a hook provided on its front end. Therefore, The operation is cumbersome, and there is a problem that the cord and the suspension rope are intertwined and entangled, resulting in poor operability. In addition, because of the heavy weight, one hair curler is hung on one cord, thereby increasing the number of cords, and since the above-mentioned hanging rope is added in addition to the cord, not only the structure is further complicated, but also Also make the weight of curler further increase.

In such hair curler devices, it is necessary that the weight of the hair curlers is not transmitted to the head of the person to be curled. Therefore, on the power distribution box arranged above the head of the person to be permed, a sling rope winding-in cylinder is arranged, and the length of the rope sent out from the winding-in cylinder is adjusted. In addition, the sling rope is hung on one end of the hair curler. Perhaps on the hook at both ends, in order not to apply load to the head of the person to be permed, adjust the length of the rope so that it is in a state of tension, so that the perm is carried out in a suspended state.

In this way, during the perm process, if the person to be permed moves the head from the initially adjusted position to the left and right, the tension state of the cord and the sling will change and lose balance; , then the weight of the curler is directly applied to the head, which will cause pain to the permed person. On the contrary, if the cord and the sling are over-tensioned, the hair will be stretched, which will also make the permed person feel uncomfortable. Therefore, the permed person must maintain the initial posture from the beginning to the end of the perm, resulting in a particularly painful state of losing the degree of freedom. In addition, the hair curlers are suspended from the head, and many cords and cords are intertwined. Since the hair is permed while avoiding these cords and cords, the operability is extremely poor.

The present invention was made in view of the above-mentioned circumstances, and its object is as follows: To reduce the weight of hair curlers, a plurality of hair curlers can be connected to one cord, thereby reducing the number of cords, and eliminating the need for hanging ropes As a result, the weight applied to the curlers by cords and ropes can be greatly reduced. At the same time, since the number of cords is also small, the device is simplified, thereby greatly improving operability. In addition, Since the perm is performed with the cord slack instead of a suspension method with tension acting on the cord as in the past, the operability of the perm can be greatly improved, and the perm can be greatly expanded during the perm process. Freedom, eliminating the pressure from the head, you can perm in a relaxed state.
