Abstract

PURPOSE:To enable fuel to be re-charged and to enable its reuse to be attained by a method wherein a fuel injection valve is provided with a porous sheet filter for preventing liquid fuel from being passed through it and capable of passing fuel in its gaseous state. CONSTITUTION:A fuel injection valve shaft 11 arranged on a porous sheet filter not capable of passing fuel in its liquid state but capable of passing fuel in its gaseous state is operated to close a lateral hole 20 for feeding in a fuel injection valve while being normally set upright so as to prevent a fuel injection from being carried out. When use, the fuel injection valve shaft 11 is inclined to cause the lateral hole 20 for feeding inlet port within the fuel injection valve shaft 11 to be opened and to inject fuel into a lighter and fed into it. With such an arrangement, it is possible to recharge fuel into the lighter.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writer using liquefied gas as a fuel, a method for adjusting the flame length of the writer, and a method for injecting fuel into the writer, and more particularly, to a method for injecting fuel from a fuel injection port. The present invention relates to a writer that uses the liquefied gas as a fuel, a method for adjusting the flame length of the writer, and a method for injecting fuel into the writer.

[0002]

2. Description of the Related Art Disposable lighters have hitherto been frequently used. However, it is difficult to adjust the flame length of the disposable writer, and in many cases, the flame length cannot be adjusted. Therefore, even if the length of the flame is too long, the length of the flame cannot be adjusted, and the user has been confused each time the writer is used. Further, as the name implies, the disposable writer cannot be refilled with fuel once used, so improvement is required, and development of a writer capable of refilling fuel has been necessary.

[0003]

DISCLOSURE OF THE INVENTION Originally, the disposable writer is characterized by low price. Then, we tried to reduce the number of parts as much as possible and make the structure as simple as possible so that it can be manufactured at a low price as an ignition device that replaces the match. However, the low price is naturally limited, and rather, it is necessary to improve and improve the function of the writer. Moreover, in recent years, the problem of waste disposal has become a major issue due to the calls for environmental improvement and protection of nature. So even with a disposable writer,
It is an object of the present invention to provide a reusable writer that can be refilled with fuel to prevent it from being discarded as waste after being used.
