[Effect]

According to the configuration of the present invention, the heat from the heating device inside the handle is transmitted by the heat pipe, increasing the temperature of the hair curling section.

[Example-]

A first embodiment of the present invention will be described based on FIGS. 1 to 4. As shown in FIG. 2, this hair curler is composed of a hair curling part A and a handle part B. Attach the water tank 1 to the tip of the pipe 7 that forms the main body of the hair wrapping part A, and
A changeover switch S is provided in the housing 11 which is the main body of the switch. The housing 11 consists of two half-cylindrical split housings IIA and IIB.

As shown in FIG. 1, the heat pipe 2 is loosely fitted into the pipe 7 of the hair wrap section A, and its base end 2a protrudes from the pipe 7 and is inserted into the housing 11 of the handle section B. . The base end 2a of the heat pipe 2 is formed into a flat shape, and the heating devices 3 are attached to both sides. The heating device 3 consists of a resistance heating element and is connected to a power cord 21 with a lead wire 20. The pipe 7 is fixed to the housing 11 with a support 4, and the heat pipe 2 is press-fitted through a hole in the support 4. In the vicinity of the support 4, a sealing backing 5 is provided between the heat pipe 2 and the inner surface of the pipe 7. A P1 cylindrical heat storage body 6 is press-fitted over the tip of the heat pipe 2.

The heat storage body 6 has an axial protrusion 6a on its outer peripheral surface, and is fixed to the inner surface of the pipe 7 with this protrusion 6a.

A cylindrical cap 9 is fixed to the tip of the pipe 7, and a water tank 1 is fit into the cap 9 so as to be freely protrusive and retractable.

A spring 10 that urges the water tank 1 to protrude is interposed between the water tank 1 and the heat storage body 6. The water tank 1 has a water absorbent material 1a made of felt or the like inside. As shown in FIG. 3, the pipe 7 has a dovetail-shaped bristle fitting groove 7a and a steam hole 7b, and the proximal end connecting portion 8a of the bristle 8 fits into the bristle fitting groove 7a. .

The operation of the above configuration will be explained. When the changeover switch S is turned on, the heating device 3 is energized and generates heat, and the base end 2a of the heat pipe 2 is also heated at the same time. heat pipe 2
has the property of easily transmitting heat, so the heat storage body 6 at the tip
The heat of the heating device 3 is also quickly conducted, and the pipe 7 is also heated.

At this time, press the tip of the water tank l to move the water absorbing body 1a to the heat storage body 6.
Steam is generated when it comes into contact with.

Water in the water tank 1 is sent to the water absorbent body 1a by capillary action. The generated steam flows into the pipe 7 and is discharged to the outside from the steam hole 7b.

Steam entering the handle part B from the pipe 7 is caused by
This is blocked by a seal backing 5. When you stop pushing the water tank 1, the restoring force of the spring 10 causes the water absorbent body 1a to
moves away from the heat storage body 6, and the generation of steam stops.
