2. Description of the Related Art Heretofore, in order to adjust the fuel injection amount of a fuel injector of a lighter, it has been possible to adjust the fuel injection amount by providing a fuel injection amount adjustment mechanism. However, the mechanism for adjusting the amount of fuel injection is extremely complicated and is not always practical. In addition, it is difficult to adjust the fuel injection amount with the simplified fuel injection amount adjustment mechanism. Therefore, practicality cannot be expected with a simplified mechanism for adjusting the amount of fuel injection. In addition, a lighter equipped with a conventional fuel injection amount adjustment mechanism enables adjustment of the fuel injection amount,
Unable to determine the upper limit of lighter flame length,
Occasionally, accidents often occurred because of a flame that was too large.

[0003]

Therefore, in a conventional lighter fuel injection valve, the fuel injection amount is adjusted by a fuel injection amount adjusting mechanism. For this purpose, the fuel injection amount is adjusted. Although the mechanism has an extremely complicated structure, the first object of the present invention is to obtain a practical automatic adjusting device for the flame length of a lighter while avoiding a complicated structure. In addition, it was not possible to specify the upper limit of the flame length of a lighter equipped with a conventional fuel injection amount adjustment mechanism, and an accident occurred due to a flame that was too large, but that was eliminated. This is a second object of the present invention.
