[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid ejection valve structure, and more particularly, to cooking or cooking at a construction site or a reclamation site where there is no pipe for power supply or fuel gas, etc. The present invention relates to a fluid ejection valve structure disposed in a fuel container for a rice cooker that is movable for cooking rice and the like.

2. Description of the Related Art Heretofore, combustion devices such as stoves having a built-in fuel container have been manufactured and used in various places. Since the shape of the fuel container of a combustion device such as a stove is cylindrical, it is appropriate to lay the cylindrical fuel container on its side, and it is necessary to lay it down in the horizontal direction. Was. In order to take out the vaporized gas generated in the cylindrical fuel container and use it as a fuel, a vaporized gas takeout pipe is required. In the case of a cylindrical fuel container in which the vaporized gas outlet of the vaporized gas outlet pipe is laid horizontally, the vaporized gas is not discharged from the liquid phase in the cylindrical fuel container but from the vapor phase. It is usual to take out. Therefore, the vaporized gas is carried into the fluid ejection valve mechanism, where the vaporized gas is ejected from the fuel ejection port to the atmosphere through the fluid ejection valve mechanism. At that time, heat of vaporization will be taken away, and the portion of the fuel outlet and the portion supporting the fuel outlet and the portion of the metal fuel container having a large thermal conductivity will be cooled, and the fuel outlet will not be used for a long time. In this case, the flame does not elongate, the flame gradually shrinks, and eventually, even if the length of the flame is adjusted by a control valve provided on the side of the combustion device such as a stove, the flame can be expected to grow. No longer. Therefore,
For example, in a combustion device such as a cooking stove with a built-in fuel container used in restaurants, etc., even though a considerable amount of liquefied gas remains in the fuel container when the flame becomes smaller, Since fuel containers are often replaced with new ones, those fuel containers that are considered used are often disposed of. Therefore, when the used fuel container that has been disposed of is put into an incinerator as it is, a considerable amount of liquefied gas remaining in the used fuel container is exposed to the high heat in the incinerator, and the temperature rapidly rises. It rises and ruptures the spent fuel container, which in turn causes a massive explosion that can damage the walls of the incinerator and damage nearby people, causing unexpected damage. May occur.

[0003]

In a conventional cylindrical fuel container which is used by being laid down, the vaporized gas is taken out from the upper end portion of the cylindrical fuel container due to the nature of the fuel container which is used by being laid down. Even in a fuel container, residual gas may remain. Therefore, in order to remove the residual gas, it is necessary to pierce the surface of the cylindrical fuel container with a piercing tool or the like, but this is troublesome. Therefore,
It is a first object of the present invention to solve the above-mentioned problem without such troublesome work. Also, in order to fill the container made of a can with a liquid gas, the gas is communicated from the gap formed between the inner surface of the mountain cap and the outer surface of the valve housing, not from the valve stem as in the related art. A second object of the present invention is to fill a container with a liquid gas through a portion of a filling communication passage formed by an inner surface of a mountain cap and an outer surface of a valve housing. In addition, a member for suppressing the passage of the liquid gas is positioned at the opening on both sides of the liquid supply pipe formed in an L shape, and the amount of the liquid gas passing through the liquid supply pipe formed in the L shape can be made a desired amount. According to a third aspect of the present invention, the liquid gas passage suppressing member holding cap is held by the liquid gas passage suppressing member holding cap so as not to be detached from the liquid gas passing member at the rear end portion of the L-shaped liquid supply pipe. Subject.
