DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a catalytic combustion type heating device for warming a human body by utilizing heat obtained by catalytically burning a liquefied fuel gas.

[0002]

2. Description of the Related Art Conventionally, as a heating tool for warming a part of a human body, for example, a heating tool using a commercial power supply having a planar heater embedded therein has been generally used. In addition, an adhesive has been added to a disposable body warmer that utilizes heat obtained from a chemical reaction of iron oxide powder, and is used by attaching it to an arbitrary part of a human body.

[0003]

According to such a conventional heating tool, since a commercial power supply voltage is applied to the heater, it is necessary to provide a power cord and connect to the commercial power supply, and there is no power supply. There was a problem that it could not be used for outdoor use. It is also considered to use a battery instead of the power cord, but there is a problem that the battery is heavy, is inconvenient to use, and is not practical.

[0004] Further, in the case of utilizing a chemical reaction, since there is no temperature control means, it is difficult to heat the human body at an arbitrary temperature corresponding to the ambient temperature, and it is only required to use the human body for several hours at a time. Must be disposable,
They also had the problem of being uneconomical.

The present invention has been made to solve the above-mentioned problems, and can stably perform catalytic combustion even when a tension is applied to a mounting portion by the movement of a human body. It is an object of the present invention to provide a catalytic combustion type heating device that can be appropriately heated.

[0006]

According to the present invention, in order to achieve the above object, heat is generated by oxidizing air in a catalytic combustion heating section with a fuel gas stored in a fuel tank to generate heat. The heating unit is housed in a heating unit, and the heating unit is mounted on a human body by a mounting unit. An intake pipe for taking in outside air to be supplied to the catalytic combustion heating section is extended on one of the mounting sections, and a telescopic section is formed on the other mounting section.

[0007] Thereby, any part of the human body can be safely and appropriately warmed in any place without connection to the commercial power supply in accordance with the ambient temperature, and the mounting part is moved by the movement of the mounted human body. The tension acting on the intake pipe can be absorbed by the expansion and contraction portion, and the application of tension to the intake pipe can be prevented.

[0008]

The mounting unit is formed on both sides of the heating unit, and a catalyst is mounted on one of the mounting unit sides. The intake pipe for taking in the outside air to be supplied to the combustion heating part is extended, and a telescopic part is formed on the other mounting part side.The tension is caused by the movement of the human body from the state where the mounting part is superimposed and mounted on the human body. Even if the state in which the air intake works repeatedly, this can be absorbed by the expansion and contraction part provided in the mounting part, preventing breakage and misalignment due to excessive tension applied to the intake pipe. And supply it to the catalytic combustion heating section. It can sustain catalytic combustion.

According to a second aspect of the present invention, there is provided a fuel tank for storing a fuel gas, a catalytic combustion heating section for oxidizing the fuel gas and air to generate heat, and a fuel tank and a catalytic combustion heating section.
