Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair iron that supplies steam to hair wrapped around a hair wrapping pipe to curl the hair.

Traditionally available steam-type hair irons are designed to be used by wrapping the hair around a hair-wrapping pipe and sandwiching it between hair press plates.
This makes it difficult to pinch the ends of the hair, and
There is a problem in that it is cumbersome to change the device depending on whether the hair is curled inward or outward.

For this purpose, as shown in Japanese Patent Application Laid-Open No. 55-19178, a brittle (brush) is provided protruding from the circumferential surface of the hair-wrapping pipe, and the hair is wound around the hair-wrapping pipe using the brittle. However, even with the one shown in the above publication, the metal part of the hair wrapping pipe is exposed to the outside, so hair and skin may come into contact with the high-temperature metal part. It still has the problems of damaging the hair and causing hot feelings.

The present invention has been made in view of these points, and its purpose is to provide a hair iron that can safely and quickly curl hair with steam, and also has other purposes. The purpose of this invention is to provide a hair iron in which the steam emitted from each steam hole is uniform regardless of the distance from the steam generation part.

The present invention will be described in detail below based on illustrated embodiments.
In the figure, reference numeral 4 denotes a heat generating section which is a heating means, and as shown in FIG. It is configured to be sandwiched between plates 3.

The heater pipe 2 is provided with a press-fit holding protrusion 30 and a group of small protrusions 31 over its entire axial length on its outer periphery, and has a heat storage part 8 for generating steam at its tip. Further, the central tip surface of the heat storage section 8 serves as a steam generation surface 9, and the peripheral portion of the tip serves as a steam release groove 10.

The hair wrapping pipe A is composed of a molded pipe 6 having brittle 5 for hair wrapping on the outer peripheral surface, and a metal pipe 7 arranged concentrically with the molded pipe 6 on the inner peripheral side of the molded pipe 6. The heat generating part 4 is press-fit concentrically into a metal pipe 7 that serves both as a heat transfer body and to maintain the overall strength, and is supported in the hair wrapping pipe A by the press-fit holding protrusion 30. There is.

The cap 12 is attached to the tip of the hair wrapping pipe A by press-fitting the bead protrusion 13' of the hair wrapping pipe A.
A tank block 11 serving as a water supply means and having one end surface of a water absorbing body 41 exposed on the end surface on the side of the heat generating section 4 is slidably attached by 2. In addition, the bead protrusion 1 provided on the water absorbing body 41 and the metal pipe 7
a conical coil spring 1 disposed between 3 and 3;
6, the tank block 11 is urged in the protruding direction to create a space between the water absorbing body 41 and the heat storage section 8, and this part is connected to the steam generation chamber 42.
It is said that

The steam generation chamber 42 is a steam cave 43 which is a cylindrical space between the outer periphery of the heat generating part 4 and the inner periphery of the metal pipe 7.
It communicates with The steam cavity 43 and the steam generation chamber 42, which are partitioned into a plurality of chambers by the press-fit holding protrusion 30, are connected to an O-ring 14 attached to the outer periphery of the tank block 11 and a sealing 15 provided at the base end of the heat generating part 4. A closed space is formed by contacting the inner periphery of the metal pipe 7, and communicates with the outside only through the steam holes 32 provided in the metal pipe 7 and the formed pipe 6.

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 the rotatable joint 2 is connected from the rear end.
2 leads out a power cord 51 connected by
and a reflecting plate 24 are attached.

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 is transferred to the heat transfer plate 3.
heating the heater pipe 2 through or directly. The heat of the heater pipe 3 heats the metal pipe 7 by radiation, convection, and 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.

The number of press-fit holding protrusions 30 is 3 from the viewpoint of uniformly heating the inner circumference of the metal pipe 7 in the circumferential direction.
It is preferable that the number is more than one book. The small protrusions 31 are intended to increase the surface area of the heater pipe 3.

This hair iron heated as described above can generate steam by operating the tank block 11 and supply this steam to the outer circumference of the hair wrapping pipe A. That is, when the tank block 11 is pushed against the spring 16 and the water absorbent body 41 is brought into contact with the steam generation surface 9, steam is generated in the steam generation chamber 42. This steam flows from the steam relief groove 10 to the steam cave 43.
and is released from the steam hole 32.

Therefore, the hair is wrapped around the hair wrapping pipe A using the brittle 5 that is integrally formed with the molded pipe 6, and the hair is heated to an appropriate temperature by the heat generated by the heat generating part 4 provided through the metal pipe 7. At the same time, if you push the tank block 11 by hand to generate steam, the steam hole 3
2, steam is supplied to the curled hair, and hair can be quickly styled without damaging the hair or scalp.

More specifically, the brittle 5 as a hair winding means is formed in a plurality of rows divided in the circumferential direction on the outer periphery of the hair winding pipe A, and between specific rows, as shown in FIG. hole 3
2 are provided radially. For this purpose, when curling the hair, as shown in Figure 3,
The blitzle 5 ensures a distance greater than its height between the steam hole 32 and the scalp, and even if the steam hole 32 is facing the scalp, the steam coming out of the steam hole 32 will not travel straight. For this reason, the steam does not reach the scalp directly, eliminating the risk of burns.

This blitzle 5 is a molded pipe 6 made of synthetic resin.
Although the manufacturing process can be greatly simplified if it is integrally molded, it may also be constructed as a separate component made of a different material. In addition, the metal pipe 7 is located on the inner periphery of the formed pipe 6 and acts so that the temperature of each part of the hair wrapping pipe A is uniform, so it is a member with good thermal conductivity and good heat transfer. In this sense, it is preferable that the outer peripheral surface of the metal pipe 7 is formed by inserting it when forming the formed pipe 6, or press-fitting or gluing it into the formed pipe 6 after forming the formed pipe 6, so that the outer peripheral surface of the metal pipe 7 becomes the formed pipe. It is preferable that the steam holes 32, 32 of the two are in contact with the inner circumferential surface of the two.

Further, in terms of ensuring that the steam released from each steam hole 32 is uniform, it is preferable to use the arrangement shown in FIG. 6. That is, steam released from the steam hole 32 from the steam generation chamber 42 through the steam cave 43 is inevitably released from the steam hole 32 closer to the steam generation chamber 42 than from the steam hole 32 located further away. If you have a stronger tendency to curl your hair and curl it, there will be a difference in the curl.

However, as shown in FIG. 6, by making the outer diameter of the metal pipe 7 slightly smaller than the inner diameter of the formed pipe 6, excluding both ends, the difference in diameter between the two A steam reservoir 44 which is a cylindrical cavity is provided, and a metal pipe 7 is provided from the steam cavity 43.
If the steam passing through the steam hole 32 of the molding pipe 6 is made to fill up the steam reservoir 44 and then released from the steam hole 32 of the forming pipe 6, the steam reservoir 44 will act as a damper when the steam is released, and the molding Steam is uniformly released from the steam holes 32 of the pipe 6, and the hair can be uniformly styled. In this case, metal pipe 7
steam hole 32 of the molded pipe 6 and steam hole 3 of the molded pipe 6
It is preferable to make a slight shift from 2 as shown in FIG.

In the present invention, since the hair wrapping pipe is provided with brittle as described above, it is easy to wrap the hair, and the hair wrapping pipe is a metal pipe with good heat conduction properties. Therefore, each part has uniform heat, and since steam is released from the steam hole provided in the hair wrapping pipe, hair can be easily styled without having to raise the temperature of the hair wrapping pipe itself. Moreover, since the inner surface of the hair wrapping pipe is a metal pipe, the structural strength is high, and the metal pipe has good thermal conductivity, so the hair wrapping pipe can be quickly installed. It is possible to increase the temperature and quickly equalize the heat of each part of the hair wrapping pipe, and furthermore, since the temperature rise and heat equalization are quickly achieved in this way, the steam hole can be removed from inside the hair wrapping pipe. The temperature of the steam ejected through the pipe does not become low, and the steam does not condense and come out as high-temperature water, which could lead to burns.The outer surface is a molded pipe, so the high-temperature metal pipe is not heated. Despite the fact that the steam is not exposed to the outside and therefore does not cause dew condensation due to temperature drop, it is possible to eject steam without causing condensation due to temperature drop. It is safe, including the fact that high-temperature water does not spout out.
