Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a catalytic combustion hair curler device for general household use that does not require a power supply and is easy to use.

Conventional Structure and Problems Conventionally, in this type of hair curler device, as shown in FIG. It was there. However, with this configuration, when hair is wrapped around the hair wrapping section 4, especially when hair containing moisture is wrapped, the temperature drop of the hair wrapping section 4 is transmitted to the spatial bimetal 1 of the heat transfer cylinder 6 and the combustion chamber 3. hand,
The bimetal 1 controls the temperature, and therefore the response of the temperature control is extremely poor.Moreover, the temperature of the bimetal 1 is higher than that of the hair curling part 4, which causes problems in response. Therefore, the temperature of the hair wrapping section 4 was set high in advance to anticipate the drop in temperature when the hair was wrapped. However, the maximum temperature for curling and styling your hair on a daily basis is 140"C, and higher temperatures can cause damage to your hair. will be exposed to.

Unfortunately, since the bimetal 1 is located close to the catalyst 2, which is the heat source, the distance relationship between them is delicate, making it difficult to set the temperature during manufacturing, and the distance changes due to falls etc. during use. In addition, in order to sense the temperature of the space in the combustion chamber 3, the bimetal 1, which is in direct contact with the high-temperature combustion gas, is equipped with a low-expansion metal invar on the inner sleeve. However, the drawback was that only elements that sense temperature based on the difference in solid expansion of metals, such as high-expansion brass, could be used for the outer shaft.

Purpose of the invention.

The present invention solves these conventional problems, allows the temperature of the hair curling part of the hair curler to respond quickly to external factors and always maintains the set temperature, and also makes it easy to adjust the set temperature during manufacturing.

By communicating between the parts, the temperature can be automatically and quickly controlled to a preset temperature in response to changes in room temperature due to the usage environment or changes in temperature such as when hair is curled. By changing the temperature, the temperature at which the heat-sensitive element is sensitive can be set arbitrarily.Also, since the heat-sensitive element is not located in a combustion chamber with a catalytic heat source, the set temperature may change due to drops, vibrations, or shocks. It is safe to use for many years.
