Description

[Detailed Description of the Invention] The present invention relates to a hair iron that curls hair wrapped around a hair-wrapping pipe using steam. When the water supply means attached to the hair wrapping pipe is heated with a heating means to generate steam and the steam is ejected from the steam hole provided in the hair wrapping pipe, the generated steam does not flow smoothly to the steam hole. In addition, if steam accumulates near the water supply means and heats the water supply means, high-temperature water droplets form inside the hair wrapping pipe due to condensation due to the drop in steam temperature, which causes the steam to heat up. If it drips from the hole, it can cause burns.

The present invention was developed in consideration of these points, and its purpose is to control the amount of steam generated with simple operations, and to prevent the generated steam from accumulating near the water supply means. The steam is smoothly guided to the steam hole without any heat, preventing condensation in the hair-wrapping pipe due to a drop in steam temperature, and water seeping and dripping from the water supply means due to overheating of the water supply means. There is a hair iron provided.

The present invention will be described in detail below based on illustrated embodiments.
In the figure, reference numeral 1 denotes a heating element consisting of a positive temperature coefficient thermistor, which is sandwiched between a pair of heat exchanger plates 3 having a semicircular cross section and press-fitted into the heater pipe 2 as shown in FIG. These constitute a heat generating section 4 which is a heating means. The heater pipe 2 has a press-fit holding protrusion 3 on its outer periphery over the entire length in the axial direction.
0 and a group of small protrusions 31, and has a heat storage part 8 for generating steam at the tip. Further, the central tip surface of the heat storage section 8 serves as a steam generation surface 9, and the peripheral portion serves as a steam relief groove 10. 6 is a molded pipe with brittle 5 for hair wrapping on the outer circumferential surface, and a metal pipe 7 that maintains the overall strength and serves as a heat transfer body is arranged concentrically on the inner circumferential surface for hair wrapping. It constitutes the pipe A, and the heat generating part 4
are press-fit concentrically into the metal pipe 7, and the heat generating part 4 is supported by the press-fit holding protrusion 30.

At the tip of the hair wrapping pipe A, a cap 12 for slidably holding a tank block 11 serving as a water supply means is press-fitted and supported by a bead protrusion 13 at the tip of the metal pipe 7. Tank block 11
The end face of the water absorbing body 41 is exposed on the end face of the heat generating part 4, and an elastic body 16, which is a conical coil-shaped compression spring, is arranged between the water absorbing body 41 and the bead protrusion 13 provided on the metal pipe 7. The tank block 11 is biased in the protruding direction by the spring 16, and a steam generation chamber 42 is formed at a distance between the water absorbing body 41 and the heat storage section 8. The steam generation chamber 42 communicates with a steam cavity 43 partitioned into a plurality of chambers by a press-fit holding protrusion 30 between the outer periphery of the heat generating part 4 and the inner periphery of the metal pipe 7. The O-ring 14 attached to the outer periphery of the tank block 11 and the sealing 15 provided at the base end of the heat generating part 4 are in contact with the inner periphery of the metal pipe 7 to form a closed space, and the metal pipe 7 and the formed pipe 6 It communicates with the outside only through a steam hole 32 provided in the.

The metal pipe 7 and the molded pipe 6 are both fixed to the tip of a handle 20 which is divided into two pieces with a screw 21. The handle 20 has a concave concave groove 50 on the outer periphery near the tip, and a rotatable joint 22 from the rear end.
A power cord 51 connected by a power cord 51 is led out, and a power indicator lamp 23 and a reflector plate 24 are attached to the tip.

When the heating element 1 and the power indicator lamp 23 are connected to a power source and the heating element 1 generates heat, this heat heats the heater pipe 2 through the heat transfer plate 3 or directly. The heat of the heater pipe 2 heats the metal pipe 7 by radiation and convection, and also heats the metal pipe 7 by heat transfer through the press-fit holding protrusion 30, which also serves as a positioning member for the heat generating part 4 with respect to the metal pipe 7. . It is preferable that the number of press-fit holding protrusions 30 be three or more in order to uniformly heat the metal pipe 7 in the circumferential direction. still,
The small protrusion group 31 is intended to expand the surface area of the heater pipe 2.

This hair iron heated as described above can generate steam by operating the tank block 11 and supply this steam to the outer periphery of the hair wrapping pipe A. That is, when the tank block 11 is pushed against the elastic body 16 and the water absorbing body 41 is brought into contact with the steam generation surface 9, steam is generated in the steam generation chamber 42. This steam enters the steam cavity 43 from the steam relief groove 10 and is discharged from the steam hole 32. Therefore, hair is wrapped around the hair wrapping pipe A using the brittle 5 integrally molded with the molded pipe 6, and the hair is heated to an appropriate temperature by heat passing through the heat generating part 4 and the metal pipe 7. At the same time, when the tank block 11 is pushed in by hand to generate steam, the steam is supplied to the coiled hair through the steam hole 32, and the hair can be quickly styled without damaging the hair or the scalp. It is.

To describe the situation when steam is generated in more detail, when the tank block 11 is pushed in and the water absorbing body 41 comes into contact with the steam generating surface 9, the elastic body 16 is compressed as shown in FIG. However, this elastic body 16 which is a conical coil spring
The small diameter side of the elastic body 16 is fixed to the tank block 11 and the large diameter side is fixed to the bead protrusion 13 of the metal pipe 7. When compressed, this elastic body 16 becomes a conical cylinder shape, and the steam flows into the tank block 11. While preventing the steam from circulating to the surroundings, the steam flows into the steam cavity 43 due to the inclination angle a of the elastic body 16, the steam relief groove 10, and the shape of the compressed elastic body 16 itself. Therefore, the steam can be released from the steam hole 32 without difficulty, and it is also possible to prevent the steam from condensing due to a temperature drop due to heat loss caused by the steam heating the tank block 11. It is. In addition, unnecessary heating of the tank block 11 causes thermal expansion of the water 45 or the air layer 46 in the tank block 11, leading to a situation where water drips from the tip of the water absorbing body 41 into the steam generation chamber 42, causing the steam hole. Although there is a risk that high temperature water droplets may drip from 32, this can also be prevented.

In addition to the illustrated conical coil spring, the elastic body 16 may also include conical or conical bellows-shaped rubber, a composite material of a coil spring and rubber in which a coil spring is embedded in rubber or a coil spring is covered with rubber, a bamboo shoot spring, etc. Of course, it may be.

As described above, in the present invention, the water supply means is slidable in the axial direction so that when the water supply means is pushed against the elastic body, the water supply means comes into contact with the heating means. Steam can be generated in the required amount with a simple operation, and since the heating means and water supply means are kept out of contact at all times due to the elastic body, there is no possibility of inadvertently blowing out steam. Moreover, this elastic body is shaped into a conical cylinder when compressed, and the small diameter side is used as a water supply means, and the large diameter side is connected to the hair wrapping pipe, so that the generated steam is transferred to the elastic body. This shape allows steam to be guided to a hair wrapping pipe having a steam hole, and prevents harmful effects caused by steam heating the water supply means.
