DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular gas cylinder (hereinafter referred to as a "circular gas cylinder") provided in a concave disk serving as a main body. With the extra fine honeycomb honeycomb crater,
In order to generate far-infrared rays while maintaining the complete combustion and high temperature of the gas, and to control the thermal power by expansion and contraction of a coil spring provided at the fuel inlet pipe connection of the crater. The present invention relates to a ceramic portable gas stove characterized by having the above configuration.

[0002]

2. Description of the Related Art The applicant of the present invention filed Japanese Utility Model Application No. 344421 in 1996, provided a circular gas cylinder and a very fine honeycomb-shaped ceramic crater inside a concave disk body,
A portable gas stove has been proposed in which the two are connected by an appropriate conduit so that the introduced fuel and air are burned with high efficiency while appropriately controlling the mixture, and the fuel is supplied from a commercially available cassette gas cylinder.

[0003]

Although such a technique has been able to obtain a reasonable result, the high-pressure liquefied gas as a fuel does not completely evaporate and also depends on a fine mixture mixed in the fuel. Therefore, there is a problem that the ceramic crater is easily clogged, and as a result, the inside of the gas cylinder is further covered with a fine felt filter medium to filter the liquefied gas fuel, and the crater is as far as possible. The fuel delivery course had to be as long as possible so that the fuel conduit could be heated and the fuel inside could evaporate before reaching the crater. Therefore, this treatment naturally complicates the structure inside the stove and has a disadvantage of high cost. The present invention aims to remedy such disadvantages.

[0004]

Therefore, according to the present invention, the felt-like filter medium provided in the gas cylinder is an extremely efficient filter medium, and the finely-divided ceramic combustion portion is formed by the filtered fuel. In addition to preventing the clogging, the ceramic crater and the circular gas cylinder are directly connected via a coil spring to simplify and increase the efficiency of taking in the air mixed with the fuel gas, thereby improving the disadvantages of the prior art. Successful.

[0005]

According to the above configuration, the ceramic portable gas stove of the present invention can prevent the ceramic crater from being clogged by the highly filterable felt filter medium provided in the circular gas cylinder. In addition, a telescopic coil spring is fitted and connected to this circular gas cylinder and the fuel introduction pipe attached to the ceramic combustion part, and the amount of mixed air taken in is controlled by the elasticity of each coil spring piece. In addition, a fuel outflow fine-adjustment adjustment bolt is screwed onto the fuel outflow portion of the circular bus cylinder so as to adjust the combustion rate of the fuel, and a fuel inlet from the cassette cylinder of the circular gas cylinder is further provided. At the bottom of the concave disk body, at the same time, on the left, right, bottom, and back, provide an appropriate number and shape of heat radiation and air intake,
The intended problem has been solved by increasing the combustion and heat radiation effects of the stove, while enhancing the design of its appearance. The invention will now be described with reference to preferred embodiments.
