The iron body 101 of the prior art has a tong-shaped image in which the proximal end a is coupled to the rotation shaft 131 so as to be rotatable within a predetermined angle range and the heating elements 113 and 123 are mounted opposite to the distal end d. / Lower arms 111, 121.

Looking at the configuration of the iron body 101 in more detail, the gripping portion (b) is formed in the middle and the force point portion (c) positioned at the rear of the heating element at the tip side of the gripping portion is configured.

When the power is applied by such a configuration, the heating elements 113 and 123 are heated by the temperature control device 103 and the operator grasps the grip portion b and at the same time, applies a thumb and index finger to the force point portion c. When applied, the tip portion d performs the gripping operation. The hair is pinched by this gripping action, and the hair can be straightened and shaped into a desired shape by the heating elements 113 and 123 warming action.

Hair irons are used in various types according to the style and wave curl to be produced in various kinds, and can be divided into straight permanents and wave permanents, which are determined by the shape of the heating elements 113 and 123.

3A and 3B, the hair 2 is wound around the lower arm 21 and then the upper arm 11 and the lower arm 21 are impregnated with the molding agent commonly used during the permanent procedure. ) And the remaining length of the hair is wound around the outer surface of the upper arm (11) to undergo approximately four or more calibration molding steps and two cooling fixing steps as follows.

1) First step straightening shaping (S1): The hair 2 is first curled by the curved portion 3 133 of the upper heating element and the curved portion 1 233 of the lower heating element at a position approximately 1 cm away from the scalp 3. Molding is done to prevent hair rooting and volume. Thus, the hair 2 is prevented from adhering to the scalp 3 and sinking.

At this time, the volume curling is made upward by a predetermined distance away from the root side of the hair, even if the operator does not lift the shoulder by the upper arm 11 coupled to cover the lower arm 21.

2) Two-stage straightening molding (S2): After the first straightening, the hair is straightened between the flat part 131 of the upper heating element and the flat part 231 of the lower heating element through which the hair passes through, and straightening in a straight hair state. During the molding, the ridge 2311 slightly enters the invisible volume.

3) three step calibration (S3); In the two-step calibration, the hair 2 straightened through the flat portions 131 and 231 is secondly curled while passing between the curved portion 4 134 of the upper heating element and the curved portion 2 234 of the lower heating element.

4) Primary cooling fixation (C1): The straightening wave is primarily cooled and fixed while the hair having undergone the three-step straightening molding passes through the bottom face 211 of the lower arm, which is the non-heating part.

5) Four-stage straightening shaping (S4): Curing straightening is again performed while the primary cooled hair passes through the curved portion 5135 of the upper heating element after straightening the shaping.

6) Secondary cooling fixation (C2): The curled hair in the four-step correction is arranged by the upper portion 111 of the upper arm, the cooling fixation is made.

7) Five-step straightening shaping (S5): Curling correction is made once more by the curved portion 6 136 of the upper heating element to the hair that has undergone the second cooling step.

If the hair length is short, only up to four stages of straightening molding are performed in the process.

As described above, the present invention prevents hair curling and scalp adhesion of the hair by volume curling from a position about 1 cm away from the root side of the hair in the first stage straightening molding (S1), and innate curls in the second stage straightening molding (S2). After the shaping process, the remaining distracting waves are straightened.

In this way, the straightening is performed in the two-stage straightening molding (S2) to the three-stage straightening molding (S3), so that curling correction is performed, so that the wave is calibrated and cleanly formed, and then the wave proceeds to the first cooling step (C1). Helps fixation.

Thereafter, curling correction is performed once more in the four-step straightening molding (S4), followed by the second cooling step (C2).

In the present invention, the hair is sequentially dried and straightened in a separate area where the wave is bent step by step, and at the end, since the straight molding is performed in a completely dry state, the hair returns to the state before straightening due to moisture evaporation immediately after straightening, which is a problem of the prior art. Permanent hair, which has been prevented from being fixed and subsequently immobilized, is formed with a soft wave with a neat volume as if it has just been finished in a beauty salon using a roll brush and a hair dryer. Maintained to a degree.

Therefore, after permanent cleaning is not necessary at all, it is possible to maintain a clean and smooth wave at all times without going to the beauty salon.

On the other hand, in the case of a straight permanent procedure that is not a wave permanent, the first stage correcting molding (S1) to the third stage correcting molding (S3), that is, the volume is passed between the upper heating element and the lower heating element without being wound around the arm. It is straight molded with a sense of straight hairstyle.

On the other hand, by installing a gripping means 33 for pushing the distal end of the heating element in the pinching direction on the upper arm 11 and the lower arm 21, the pressure of the heating element is equally applied to the hair disposed on the distal end. Is done.

In addition, the remaining hair is pulled out when the device is rotated in the state where the hair is pinched (pulling) occurs in the present invention, the rotation unit 50 is provided in the present invention by the return spring within a predetermined angle range after the rotation of the device (53) As the tip (d) is rotated, the remaining hair continues to be pinched and the straight hair is neatly straightened to the remaining hair, and when the grip is released for a while, the tip is returned to its original position while the upper / lower arms are momentarily opened again. Repeated calibrations are made.

The predetermined angular range is determined by the fan groove 54 and the stopper 55 whose movement is restricted in the fan groove.

In the above, preferred embodiments of the present invention have been described with reference to the accompanying drawings. Here, the terms or words used in the present specification and claims should not be construed as being limited to ordinary or dictionary meanings, but should be construed as meanings and concepts corresponding to the technical spirit of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

As described in detail above, the hair iron according to the present invention is a curling correction molding after the pre-treatment of each hair in a straight hair state at a time by using a single device is performed when the permanent hair is just finished using a hair dryer in the beauty salon It can maintain voluminous and soft wave for several months as well as free effect of not only wave permanent but also straight permanent procedure as a single device.

In addition, there is an advantage that prevents the root of the hair to be rooted, improve the volume of the root side, and reduce the fatigue by the operator does not have to lift the shoulder.

In addition, since the gripping means for pushing the distal end of the heating element in the pinching direction is provided, the pinching pressure is uniformly applied to perform the procedure efficiently, and the straightening molding is neatly performed without pulling the remaining hair.
