Alternatively, since the second treatment surface is formed of a concave curved surface having a smaller curvature than the first treatment surface, the hair is locally sandwiched between the tip of the first treatment surface and the second treatment surface. Thus, sufficient curling can be performed.

In addition, since the second processing surface is a flat surface or a concave curved surface having a smaller curvature than the first processing surface, there is a displacement between the first and second processing surfaces due to the backlash of the holding arm during the holding operation. Even if it occurs, the deviation can be absorbed and the hair can be securely held between the first and second treatment surfaces, and the curling of the curl can be performed reliably.

When the temperature control is performed so that the temperature difference between the first and second processing surfaces is generated between the first and second processing surfaces, sufficient curling wrinkles can be obtained by heating the hair with the temperature difference between the inside and the outside. You can make it.

When the temperature control is performed within a temperature difference range of 120 ° C. to 180 ° C., the temperature difference between the inside and the outside becomes suitable for curling, and the curling of the curl can be more reliably performed.

When the temperature control is performed only on the first processing surface in the range of 120 ° C. to 180 ° C., the internal and external heating temperatures and the temperature difference are suitable for curling, and the curling of the curl is more reliably performed. be able to.

The purpose of sufficient curling of the curl was realized by a hair iron that locally pinches the hair.

Next, a case where curling is performed using the hair iron 1 will be described.

First, when the hair iron 1 is used, a basic substance such as ammonia, monoethanolamine, triethanolamine or the like is added to an aqueous solution mainly containing a mercapto compound (reducing agent) such as thioglycolic acid or cysteine on the hair. Is added to the solution adjusted to pH 6-10. By this application, the disulfide bond of cystine contained in the keratin protein in the hair is reduced and cleaved as a mercapto group. Thereafter, the hair is washed with water and dried with a dryer or the like, and then curled on the hair by the treatment of the heated hair iron 1.

Specifically, the temperature of the ceramic heater 69 is controlled by the control of the temperature control device 4, and the ceramic heater 69 is controlled to be heated to 120 ° C. to 180 ° C. And
The gripping portions 21 and 23 of the sandwiching arms 7 and 9 are gripped, and force is applied by applying a thumb and an index finger to the force application portions 25 and 27 to sandwich the hair between the hot plates 67 and 68 of the treatment bodies 11 and 13. Thereby, hair is pinched between the 1st process surface 72 of the hot plate 67, and the 2nd process surface 78 of the hot plate 68, and the 120 degreeC-180 degreeC heating of the 1st process surface 72 is carried out. Rapid heat stress is applied only to the inside of the hair.

At this time, since the magnet plate 71 is set so that the S poles are opposed to each other, when the processing bodies 11 and 13 approach each other by the holding operation of the holding arms 7 and 9, the magnet plate 71 repels each other, At the same time, the second spring 75 is bent in response to the repulsion, so that the magnet plates 71 are parallel to each other. Thereby, the processing body 11
, 13 are corrected in posture, and the correction surfaces 72 and 78 become parallel. Therefore, when the processing surfaces 72 and 78 of the processing bodies 11 and 13 are brought into close contact with each other by further progress of the holding operation,
Close contact can be made in a parallel state from the beginning.

At the time of the holding heating, the first processing surface 72 is a convex curved surface and the second processing surface 78 is a flat surface. Therefore, the tip of the first processing surface 72 and the second processing surface 78 are The hair is pinched locally only at one point of the opposite portion. Therefore, a sudden heat stress can be locally applied to the hair.

Thereafter, while maintaining this state, the hair iron 1 is gradually rotated with the holding arm 7 inward while sliding the holding arms 7 and 9 toward the hair ends. This makes it possible to reliably perform artificial curling of the curl while continuously applying local heat stress to the hair. If you want to stretch the eyelashes or correct artificial curls,
Without rotating the hair iron 1, the holding arms 7 and 9 are slid to the hair tips.

When the holding arms 7 and 9 are slid, the holding force between the holding arms 7 and 9 is slightly relaxed so that the second spring 75 does not bend completely. Thereby, even when the hair has a thick hair bundle or a thin hair bundle, the second spring 75 bends to cause the first and second holding surfaces 72 and 78 to follow the thick hair bundle or the thin hair bundle. Can be first, second
The holding arms 7 and 9 can be smoothly slid while the hair is reliably held by the holding surfaces 72 and 78.

Moreover, since the first treatment surface 72 and the second treatment surface 78 locally pinch the hair linearly at one point, the holding arms 7 and 9 can be easily and smoothly slid with respect to the hair. The curl brazing operation can be easily performed.

Furthermore, by sliding the holding arms 7 and 9, tension can be given to the hair, and the hair can be surely pressed against the second treatment surface 78 and the curling of the curl can be reliably performed. it can.

Further, since the second treatment surface 78 is a flat surface, it is caused by frictional resistance between the nail arms 7 and 9 and the hair and the first and second treatment surfaces 72 and 78 during the sliding. Even if a shift occurs between the first and second processing surfaces 72 and 78, the shift is absorbed to the first
The hair can be securely held between the second treatment surfaces 72 and 78, and the curling of the curl can be reliably performed.

Since the second processing surface 78 is a plane that is substantially perpendicular to the clamping direction, even when the second processing surface 78 is displaced from the first processing surface 72 as described above, the clamping arms 7 and 9 are narrowed. The holding force can be reliably applied to the hair as a holding force with the first treatment surface 72, and the curling of the curl can be reliably performed.

On the other hand, since the hair moves at a predetermined speed between the magnet plates 71 facing the south pole, reduction energy is generated according to Fleming's right-hand rule. This energy is generated from the south pole of the magnet plate 71 in which the electrons of the magnetic pole rotate to the right, and promotes the reducing action of the first liquid. Moreover, it also serves to close the cuticle that forms the surface layer of the hair. When the cuticle is closed, ultraviolet rays can be prevented from entering the hair, and the hair can be prevented from being damaged by the ultraviolet rays.

Moreover, the cluster of the water of a 1st liquid becomes small with the energy of this reduction. By reducing this cluster, the permeability of the first liquid into the hair is increased. Therefore, the reducing action of the first liquid is further promoted. As a result, it is possible to shorten the treatment time with the risk of damaging the hair, and it is possible to suppress hair damage.

After that, a second liquid composed of an aqueous solution of an oxidizing agent such as sodium bromate or hydrogen peroxide was applied to the hair, and as a result, the mercapto group was oxidized to generate a new disulfide bond in the hair, and this curled state was changed. Can be immobilized.

As described above, when curling is performed by pinching hair in a wide range between a pair of treatment surfaces that are generally opposed to each other as in the conventional case, curling in a local or minute range is performed. Although the brazing force was weakened, and curling of the curl could not be sufficiently performed, according to the hair iron 1 of the present example, the first contact was made locally.
By the second treatment surfaces 72 and 78, the hair can be pinched and heated locally to curl the curl reliably.

In this embodiment, since the first treatment surface 72 and the second treatment surface 78 locally pinch the hair linearly at one point, the holding arms 7 and 9 can be easily slid with respect to the hair. The curl brazing operation can be performed easily and reliably.

Furthermore, by sliding the holding arms 7 and 9, the hair can be tensioned and the hair can be surely pressed against the first treatment surface 72, and the curling of the curl can be more reliably performed. it can.

In addition, in the present embodiment, since the second processing surface 78 is a flat surface, the holding arm 7
, 9 is slid against the hair, even if a deviation occurs between the first and second treatment surfaces 72, 78, the deviation is absorbed and the hair between the first, second treatment surfaces 72, 78 is absorbed. Can be securely held and curling of the curl can be performed reliably.

In this embodiment, since the temperature of the ceramic heater 69 is controlled so that a temperature difference occurs between the treatment bodies 11 and 13 during the warming, the hair is sufficiently curled with the temperature difference between the inside and outside. be able to.

In this embodiment, since the temperature difference is controlled in the range of 120 ° C. to 180 ° C., the temperature difference between the inside and outside becomes suitable for curling, and curling of the curl can be performed more reliably.

In this embodiment, the first processing surface 72 is controlled in a range of 120 ° C. to 180 ° C.,
Since the second processing surface 78 is set to room temperature, the heating temperature and temperature difference between the inside and outside are more suitable for curling, and curling of the curling can be performed more reliably.

Note that the second processing surface can be modified as shown in FIG. FIG. 10 is a front view showing the tip side of the hair iron. As shown in FIG. 10, the hair iron 1 </ b> A includes a second processing surface 78 </ b> A instead of the second processing surface 78 of the first embodiment. The second processing surface 78 </ b> A is formed by a concave concave curved surface having a smaller curvature than the first processing surface 72.

In the hair iron 1A, in addition to having the same operational effects as in the first embodiment, when the holding arms 7 and 9 are slid with respect to the hair, the distance between the first and second treatment surfaces 72 and 78A is reduced. Even if a deviation occurs, the first processing surface 72 is guided to the center side by the concave shape of the second processing surface 78A, and the deviation is corrected. Accordingly, it is possible to reliably maintain the nipping state between the first and second processing surfaces 72 and 78A and perform more reliable curling.

In addition, this invention is not limited to the said Example, A various change is possible. For example, one or both of the treatment bodies 11 and 13 may be fixed so that they cannot move with respect to the distal end sides 29 and 31. Magnet plate 71, first spring 7
