Abstract

PROBLEM TO BE SOLVED: To provide a hair iron which shortens the application time, is neat in the finish after the application and hardly damages the hair. SOLUTION: The hair is moved at a prescribed speed between magnets 13 of which S poles are disposed to face each other after the application of a first liquid to the hair. Reduction energy is, therefore, generated from the S poles of the magnets 13 in which the electrons of the magnetic poles are rotated clockwise by Fleming's right-hand rule. As a result, the reduction effect of the first liquid is accelerated. A cuticle is closed to prevent the intrusion of UV rays into the hair. The clusters of the water of the first liquid are made smaller by the reduction energy and the penetratability of the first liquid into the hair is enhanced. Consequently, the reduction effect of the first liquid is further accelerated and the time required for the application which is liable to be accompanied by the damage of the hair may be shortened. Accordingly, the finish after the application is made neat and the hair may be made hardly damaged.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair iron and, more particularly, to a hair iron for applying a straight permanent or permanent wave to hair.

[0002]

2. Description of the Related Art Straight irons are known as a device for extending natural hair and correcting artificial permanent waves. A conventional straight iron has a structure in which a pair of hair-clamping arms whose bases are pivotally mounted, and a heating element (heater) is attached to each of the hair-clamping arms at a position facing the distal end. . At the time of using this straight iron, first, an aqueous solution mainly containing a first agent, that is, a mercapto compound (reducing agent) such as thioglycolic acid or cysteine, is added to the hair.
A basic substance such as monoethanolamine or triethanolamine is added, and a solution adjusted to pH 6 to 10 is applied. By this application, the disulfide bond of cystine contained in the keratin protein in the hair is reduced and cut as a mercapto group, and then, after washing the hair with water,
This hair is straightened with a straight iron heated to 160-180 ° C.

[0003] Specifically, the roots of the hairs are pinched by the ends of both hair holding arms, and the hair holding arms are slid to the hair tips as they are. As a result, the hair heated by the heat of the heating element is lengthened and becomes straight straight hair. In addition,
Thereafter, a second solution consisting of an aqueous solution of an oxidizing agent such as sodium bromate or hydrogen peroxide is applied to the hair, and as a result, the mercapto group is oxidized to generate a new disulfide bond in the hair. Will be fixed.

[0004]

However, such a conventional straight iron has the following problems. That is, since the hair was simply heated by the heating element, the treatment time was relatively long. This usually results in 160-180
The hair was easily damaged at the time of performing the treatment while applying high heat of the heating element of ℃ and exposed to the first liquid of the reducing agent, and the finish of the hair after the treatment was poor.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hair iron which can shorten the treatment time, has a beautiful finish after the treatment, and is hard to damage the hair. Another object of the present invention is to provide a hair iron that can lower the heating temperature of hair by a heater during treatment and can prevent hair loss.

[0006]

According to a first aspect of the present invention, there is provided a hair iron having a pair of hair holding arms for holding hair, wherein the hair holding arm is provided with a heating element for heating hair. And a hair iron in which a pair of magnets are disposed with their S poles facing each other at positions opposed to both hair holding arms. Hair is not limited to human hair,
Including pet hair such as dogs and cats. The hair-clamping arm
The material, shape, number, and the like are not limited as long as the hair can be sandwiched.

[0007] The material, size, shape, mounting position and the like of the heating element are not limited. As a material, various heaters such as a ceramic heater can be adopted. The shape is
It may be an elongated plate or the like. This heating element is usually arranged on the inner side of the two hair holding arms facing each other. However, the present invention is not limited to this, and may be provided on only one of them. In addition, as the magnet, for example, an electromagnet wound with a coil can be employed in addition to various permanent magnets such as neodymium. Further, both the permanent magnet and the electromagnet may be used in combination. Furthermore, as a magnet, 10,000
Gauss or more, especially 15,000 gauss or more is preferable. The magnets must be arranged at least one each at a position facing the both hair holding arms. Moreover,
These magnets need to be arranged with their south poles facing each other.

According to a second aspect of the present invention, there is provided a hair iron provided with a high-frequency vibrator for applying high-frequency vibration to hair on the hair holding arm. The high-frequency vibrator may be provided on both or any one of the two hair holding arms. The material of the high-frequency vibrator is not limited. For example, barium titanate or the like can be employed. Further, the high-frequency vibration generator that vibrates the high-frequency vibrator is not limited. For example, an electric signal generating unit that generates an electric signal in a high frequency region, a converter (piezoelectric element) that converts a signal from the high frequency region into mechanical vibration in a high frequency region, and a high frequency vibration through a booster. Device. Further, hair may be heated by high frequency from a high frequency oscillator.

[0009]

According to the present invention, for example, after the first liquid is applied to the hair, the hair is pinched by the ends of both hair holding arms, and the hair holding arm is slid to the hair tips as it is, the heat of the heating element is increased. The hair heated by is stretched and becomes straight straight hair. At this time, the hair moves at a predetermined speed between the magnets facing the S pole. By this, Fleming's right hand rule, that is, when moving the lead perpendicular to the magnetic field line in the magnetic field perpendicular to the magnetic field, the index finger and the right finger of the right hand move in the direction of the magnetic field and the direction of the movement of the conductor, Energy is generated by the law that the current flows in the direction of the middle finger pointing perpendicular to them.

[0010] This energy is generated as a force by which the electrons of the magnetic pole promote the reducing action from the S pole of the right-rotating magnet. Accordingly, this energy promotes the reducing action of the first liquid and also functions to close the cuticle forming the surface layer of the hair. When the cuticle closes, it blocks UV light from trying to enter the interior of the hair. Moreover,
The cluster of water of the first liquid is reduced by this energy. When the clusters of water are reduced in this way, the permeability of the first liquid to the hair is increased. Thereby, the reducing action of the first liquid is further promoted. As a result, it is possible to shorten the treatment time in which the hair is easily damaged. Therefore, the finish after the treatment is beautiful, and the hair is not easily damaged.

In particular, according to the second aspect of the present invention, the high-frequency vibrator of the hair-clamping arm is vibrated during the treatment. By the action of this high frequency, the heating temperature of the hair by the heating element at the time of treatment can be reduced from, for example, about 160 to 180 ° C. to, for example, 120 ° C. or less. In addition, since the high frequency vibration stimulates the scalp, the effect of preventing hair loss can be obtained.

FIG. 2 is an enlarged front view of a heat conductive plate and a magnet used in a hair iron according to one embodiment of the present invention.
FIG. 3 is a cross-sectional view of a hair-clamping arm used in a hair iron according to one embodiment of the present invention.

In FIG. 1, reference numeral 10 denotes a hair iron according to an embodiment of the present invention.
Is a pair of hair-clamping arms 11 for clamping hair, a pair of heaters H provided on both hair-clamping arms 11 and heating elements for heating hair, and satisfactorily transfers heat generated by each heater H to the hair side. A pair of heat conductive plates 12 to be transmitted and a pair of magnets 13 provided at opposing positions of the hair holding arms 11 with their S poles facing each other. Each of the two hair holding arms 11 is made of a synthetic resin material, and has a structure in which two partial arms 11a that are halved at an intermediate position in the width direction are fitted and connected. The bases of the hair holding arms 11 are rotatably supported by a shaft 14 made of the same synthetic resin material.
Inside each hair holding arm 11, a groove 11b extending in the arm length direction is formed. A power cord 15 is connected to the base of one of the hair holding arms 11.

Each of the heaters H is a horizontally long plate-shaped member, and heats the hair to a maximum temperature of 180 ° C. via the heat conductive plate 12. Each of the heat conducting plates 12 is a horizontally long material made of aluminum and the front surface thereof is coated with fluorine, and a storage groove of the heater H is formed on the back surface of the horizontally long material.
On the back surface at both ends in the width direction of the heat conductive plate 12, hook portions 12a, 12b having slightly different shapes for engaging the heat conductive plate 12 with the corresponding groove portions 11b of the hair holding arm 11 are provided.
Are integrally formed. These opposing hooks 12
A magnet storage part is provided between a and 12b. The magnet 13 is housed in this magnet housing.

As the magnet 13, a 15000 gauss neodymium magnet, which is a kind of permanent magnet, is employed. The magnet 13 may be reduced in magnetic force when exposed to high heat. Therefore, the outer surface is covered with a silicone rubber packing 16 made of heat-resistant rubber. Further, the magnet 13 is provided with each of the facing locking portions 12a,
The large and small magnet hooking pieces 12c and 12d, which are different from each other in shape and protrude from the magnet 12b, are held so as to be wrapped inside the magnet housing portion. In the figure, reference numeral 17 denotes an arm holding stopper that is provided to protrude from the inner surface near the base of one of the hair holding arms 11 and keeps a constant arm interval when the arm is held.

Next, a method of using the hair iron according to one embodiment of the present invention will be described. After applying the first liquid to the hair, as shown in FIG. 1, the hair is sandwiched between the heat conducting plates 12 while holding both hair holding arms 11 in a hand. Thereafter, the hair holding arm 11 is slid to the tip of the hair while maintaining the state. Thus, the hair sandwiched between the heat conductive plates 12 heated by the heater H is stretched while being heated. Therefore, straight hair is obtained. At this time, the hair
It moves at a predetermined speed between the magnets 13 facing the south pole. Thereby, reduction energy is generated by Fleming's right-hand rule. This energy is generated from the S pole of the magnet 13 in which the electrons of the magnetic pole rotate clockwise, and promotes the reducing action of the first liquid. In addition, it also functions to close the cuticle forming the surface layer of the hair. When the cuticle closes, it can block UV light from entering the interior of the hair and prevent the hair from being damaged by the UV light. Also, the energy of this reduction reduces the size of the cluster of water in the first liquid. By reducing the size of the cluster, the permeability of the first liquid to the hair is increased. Therefore, the reducing action of the first liquid is further promoted. As a result, it is possible to shorten a treatment time accompanied by a risk of damage to the hair. As a result, the finish after the treatment is beautiful, and the hair is not easily damaged.

A high-frequency vibrator (not shown) may be provided on the hair-clamping arm 11 to vibrate the heat-conducting plate 12 during this operation. By doing so, the action of the high frequency can reduce the heating temperature of the hair by the heater H during the treatment from about 160 to 180 ° C. in the past to, for example, 120 ° C. or less. In addition, since the high frequency vibration stimulates the scalp, the effect of preventing hair loss can be obtained.

[0018]

According to the present invention, since the magnets whose S poles are opposed to each other are disposed at the opposing positions of the pair of hair-clamping arms, the operation can be shortened. The finish is beautiful and the hair is not easily damaged.

In particular, according to the second aspect of the present invention, since the high-frequency vibrator is attached to the arm portion, the heating temperature of the hair by the heating element can be reduced, and hair loss can be prevented.
