[First embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the hair iron 1 of this embodiment includes a main body 10, a heat plate 20, a plurality of heat protectors 30, a pair of upper comb portions and a pair of

lower comb portions

40a and 40b (in FIG. 1). (Not shown for the lower part 40b).
(About main unit 10)
The main body 10 is a rod-shaped support member formed in a substantially circular or elliptical cross section. A heat plate 20 and a plurality of heat protectors 30 that cover a part of the heat plate 20 are provided at approximately half of the longitudinal direction from the front end of the main body 10 toward the base.
The remaining half of the main body 10 in the longitudinal direction functions as a grip portion 12 gripped by the user.

Inside the main body 10, a heating element that generates heat upon being supplied with electric power is disposed (not shown). The heating element is, for example, a heating wire or a metal plate. The heating element generates heat when power is supplied from a power cord 10 c provided at the base of the main body 10. The heating element is in contact with the heat plate 20 inside the main body 10, and when the heating element generates heat, this heat is transmitted to the heat plate 20, and as a result, the heat plate 20 generates heat. In addition, without providing a heating element inside the main body 10, power may be directly supplied to the heat plate 20 via the power cord 10c to cause the heat plate 20 to generate heat directly.

The grip part 12 includes a switch part 10b. The switch unit 10b is for receiving an On / Off operation by the user. The switch portion 10b is for receiving a temperature setting operation when applying curl or the like to the hair.
The switch portion 10b is electrically interposed between the heating element and the power cord 10c. The switch unit 10b includes an electric circuit for increasing or decreasing the supply amount of the power supplied from the power cord 10c to the heating element. The electric circuit is composed of electronic elements. The amount of power supplied to the heating element can be increased or decreased by this electric circuit. As a result, the temperature of the heat plate 20 can be raised or lowered to a temperature desired by the user.
By supplying the radiated heat to the user's hair due to the heat generated by the heat plate 20, curling or the like can be easily applied to the hair.

(About heat plate 20)
In FIG. 1, the portion corresponding to the heat plate 20 is hatched to make the drawing easier to see. The heat plate 20 is disposed at the end of the main body 10. The heat plate 20 functions as a winding drum heated by electric heat. Since the heat plate 20 generates heat at a high temperature, it is desirable that the heat plate 20 be formed of a good thermal conductor. For example, the heat plate 20 is formed of ceramics or metal.

The heat plate 20 has a curved surface corresponding to the outer peripheral surface of the main body 10. The heat plate 20 is provided in close contact with the main body 10 with an adhesive or screwing. The heat plate 20 can be formed in various shapes. Specifically, the heat plate 20 is a plurality of rectangular metal plates having curved surfaces corresponding to the outer peripheral surface of the main body 10, a plurality of semi-cylindrical metal plates, or a cylindrical metal plate. There is. The heat plate 20 is bonded or screwed to the outer peripheral surface of the main body 10 by combining any one or more of these. And the heat plate 20 is arrange | positioned so that it may become a cross-sectional substantially circular shape as shown in FIG. 2 as a whole. The heat plate 20 may be formed to have a substantially elliptical cross section corresponding to the cross sectional shape of the main body 10.
The heat plate 20 is provided with a hole 20a for inserting a pair of upper comb portions and a pair of lower comb portions and a pair of upper comb portions and a pair of

lower comb portions

40a and 40b.

(About multiple heat protectors 30)
The plurality of heat protectors 30 are members for preventing the user from feeling hot or being burned. Therefore, it is desirable that the heat protector 30 be formed of a poor heat conductor that does not reach a high temperature. For example, the heat protector 30 may be formed of a heat resistant plastic such as polyethersulfone (PES) or polyetheretherketone (PEEK).
The plurality of heat protectors 30 may be provided by, for example, using a plate of metal or the like as a core member and coating the core member with a heat-resistant plastic or the like. Thus, the rigidity of the heat protector 30 can be improved by using a metal plate as a core member.
The plurality of heat protectors 30 are disposed on the outer peripheral surface of the heat plate 20 on the central axis of the main body 10 (see reference numeral A in FIGS. 1 and 2) so as to be interposed between the heat plate 20 and the user's skin. They are provided so as to be orthogonal to each other.

By providing the heat protector 30 on the surface of the heat plate 20, it is possible to balance the prevention of burns and the effective supply of heat released from the heat plate 20 to the hair.

(About a pair of upper comb part and a pair of

lower comb part

40a, 40b)
The pair of upper comb portions and the pair of

lower comb portions

40a, 40b (especially, see FIG. 2) have substantially the same configuration and function, and therefore, the pair of upper comb portions 40a will be mainly described here.
The pair of upper comb portions 40 a is provided so as to protrude from the winding drum portion of the main body 10 provided with the heat plate 20 with the base portion parallel to the central axis of the main body 10.
This will be described in detail. The pair of upper comb portions 40a is composed of a plurality of

pin bodies

41a and 42a, respectively. The base portions of the plurality of

pin bodies

41 a and 42 a are respectively arranged in a straight line so as to be parallel to the central axis of the main body 10 and provided on the side surface of the main body 10. The pin body 42a is provided on the side surface opposite to the side surface of the main body 10 provided with the pin body 41a.

The plurality of

pin bodies

41a and 42a are provided so that the tip portions thereof are orthogonal to the central axis of the main body 10 from between the plurality of heat protectors 30 through the hole 20a.
The

pin bodies

41 a and 42 a are desirably heat-defective conductors formed of a heat-resistant plastic like the heat protector 30. However, the

pin bodies

41a and 42a may be formed by, for example, using a pin-shaped metal or the like as a core member and coating the core member with a poor heat conductor.
The

pin bodies

41a and 42a may be formed integrally with the heat protector 30. That is, the

pin bodies

41 a and 42 a may be provided so as to protrude from the heat protector 30. In this case, it is not necessary to provide the hole 20a in the heat plate 20. Thus, by forming the

pin bodies

41a and 42a integrally with the heat protector 30, it is possible to reduce the manufacturing process and the cost.

The

pin bodies

41a and 42a function as guides for guiding the hair near the heat plate 20 while adjusting the flow of the user's hair. By adjusting the flow of the hair by the

pin bodies

41a and 42a, the heat from the heat plate 20 is easily supplied to the hair evenly. As a result, curling and the like can be easily and quickly performed.
The lower comb portion 40b includes a plurality of

pin bodies

41a and 42a constituting the upper comb portion 40a and

corresponding pin bodies

41b and 42b.

(how to use)
Next, the usage method of the hair iron 1 comprised as mentioned above is demonstrated using FIG. Here, the user is a woman with long hair. Then, it is assumed that the user uses the hair iron 1 to curl his own hair.
First, the user sets (selects) the heat generation temperature of the heat plate 20 by operating the switch unit 10b. In the hair iron 1, it is assumed that the setting of the heat generation temperature and the heat generation On operation can be performed together. That is, the supply of electric power to the heat generating part in the main body 10 is started from the moment when the heat generation temperature is set. As a result, the heat plate 20 has heat at the set temperature.

Here, the user brings a part of the heat plate 20 into contact with his hair. Then, the user lowers the hair iron 1 toward the longitudinal direction of the hair while rotating the hair iron 1 in the direction of the arrow shown in FIG.
At this time, the hair is guided along the vicinity of the outer peripheral surface of the heat plate 20 while the flow of the hair is adjusted by the upper comb portions and the

lower comb portions

40a and 40b. As a result, the heat of the heat plate 20 can be uniformly applied to the hair. Since the outer peripheral surface of the heat plate 20 has a substantially circular cross section, the user's hair can be easily curled by this shape and the supply of heat. That is, it can be easily applied to the user's hair.

At this time, the heat protector 30 prevents contact between the user's skin and the heat plate 20. Therefore, it is possible to prevent the user from feeling hot or being burned. In the hair iron 1, since the user's skin can be protected from heat by the heat protector 30, the heat plate 20 can generate heat at a higher temperature than the conventional hair iron.
In short, when the hair iron 1 is used, it is possible to prevent the user from feeling hot or getting burned during the setting, and good operability can be obtained.

[Modification 3]
Furthermore, like the hair iron 4 shown in FIG. 7, the hair iron 1 described in the first embodiment (see FIG. 1 and the like) has a function of generating negative ions and treating hair. Good.
Specifically, as shown in FIG. 7, an opening 12 a having a predetermined size extending to the inside of the grip portion 12 is provided at a predetermined portion of the grip portion 12 (here, in the vicinity of the heat plate 20). Furthermore, a pair of discharge electrodes 50 are provided in the grip portion 12 so as to face each other. Further, a high voltage generator 51 for applying a high voltage to the pair of discharge electrodes 50 is disposed inside the grip portion 12.
The pair of discharge electrodes 50 are desirably provided so that one end portions are exposed from the wall surface of the opening 12a.

The high voltage generator 51 includes a booster circuit. The high voltage generator 51 is supplied with power through the power cord 10c. The high voltage generator 51 boosts the voltage based on the supplied power. Finally, the high voltage generator 51 applies the boosted voltage to the pair of discharge electrodes 50. In the high voltage generator 51, On / Off of voltage application to the discharge electrode 50 is controlled by the switch unit 10 b. It is desirable to cover the opening 12a with a mesh-like cover 52 so that the user does not get hurt by touching the discharge electrode 50 to which a voltage has been applied.

With the configuration as described above, the discharge electrode 50 to which a high voltage is applied causes atoms and molecules in the air in the opening 12a to obtain electrons and be negatively charged, so-called negative ions are generated. The generated negative ions are released from the gap of the cover 52, and a treatment effect that gives gloss or firmness to the hair near the opening 12a can be expected.
This will be described in detail. When negative ions are generated, moisture in the air may be refined. This refined moisture effectively penetrates and is absorbed by the hair. At this time, it is said that the hair's metabolic function is promoted by the moisturizing effect and the action of mineral ions, and the water combined with the negative ions regenerates and repairs the cuticle damaged by, for example, static electricity. As a result, it is possible to expect the effect of giving the hair firmness and luster, and improving the hair quality to a smooth and smooth texture.

Here, it has been described that the pair of discharge electrodes 50 are disposed so that one end portion is exposed from the wall surface of the opening 12a. However, instead of the discharge electrodes 50, a discharge tube (ozone tube) formed in a columnar shape. Can also be arranged. At this time, it is desirable to arrange the discharge tube in the opening 12a so that the surface of the discharge tube is exposed to the outside of the grip portion 12. This discharge tube is, for example, a tube made of quartz glass filled with low-pressure mercury vapor.
When a high voltage generated by the high voltage generator 51 is applied to the discharge tube, ultraviolet rays are emitted to the outside of the discharge tube. Ozone (O ₃ ) is generated in the vicinity of the discharge tube by the action of the ultraviolet rays. The generated ozone is released from the gap between the covers 52. As a result, a treatment effect that gives gloss or firmness to the hair near the opening 12a can be expected.

The concentration of ozone generated here is preferably less than 0.1 ppm. Further, considering the deodorizing and bactericidal effects for removing germs that cause dandruff, itching, and offensive odor, the ozone concentration is preferably about 0.004 ppm to 0.06 ppm, for example. In order to obtain a suitable cosmetic effect on the scalp and hair, it is preferable that ozone is generated at a concentration of about 0.06 ppm to 0.09 ppm, for example.
Simultaneously with the generation of ozone, negative ions may be generated when ultraviolet rays emitted from the discharge tube pass through the air. In this case, a higher treatment effect due to the ozone and negative ions described above can be expected.

As a further modification, like the hair iron 5 shown in FIG. 8, the opening 12a, the discharge electrode 50, the high voltage generator 51, and the like described in the modification 3 (see FIG. 7) are used in the second embodiment (see FIG. 4). You may make it provide in the hair iron 2 demonstrated in).
In this case, the opening 12a, the discharge electrode 50, and the like can be provided in the upper arm portion and / or the

lower arm portions

211a and 211b. Of course, instead of the discharge electrode 50, the hair iron 5 may be provided with a discharge tube (ozone tube) formed in a columnar shape.
