Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pocket lighter, and in particular, it can be used in a normal use mode represented by ignition of a cigarette or the like and a remote ignition form represented by ignition of a stove or fireworks. The present invention relates to a portable pocket lighter that can be used by switching.

[0002]

2. Description of the Related Art In a conventional pocket lighter, a nozzle is arranged inside a windshield so that a combustion flame generated by ignition is emitted from a flame burnout hole provided in the windshield. Therefore, although there is no particular problem in igniting a cigarette or the like, when trying to ignite a firework or a stove, it is dangerous because the hand holding the lighter is easily exposed to the combustion heat of the ignition. In order to avoid such a danger, there is a special lighter in which a nozzle is largely projected from the lighter body, but in this case, there is a problem that portability is poor because the lighter becomes large.

[0003]

SUMMARY OF THE INVENTION The present invention is capable of producing a combustion flame in a normal use mode in which a combustion flame is burned out from a flame burnout hole provided in a windshield, and a combustion flame in a protruding position far away from the flame burnout hole. An object of the present invention is to diversify the use mode without impairing the portability, which is the original function of the pocket lighter, by making it possible to arbitrarily switch the remote ignition mode.

[0004]

In order to solve the above problems, the present invention is a pocket lighter in which a nozzle faces a flame burnout hole provided in a windshield, and the nozzle is configured to be retractable from the flame burnout hole. In addition, it is characterized in that a switching means for switching between two positions, that is, a lowered position where the nozzle is located inside the windshield and an elevated position where the nozzle is projected from the flame outlet to the outside of the windshield is provided.

[0005]

In the state where the nozzle is located inside the windshield, as in the case of a normal pocket lighter, the protective action of the windshield prevents the combustion gas ejected from the nozzle from scattering, so that good ignition is performed. Be done. On the other hand, when the nozzle is operated to project to the outside of the windshield, a combustion flame is generated at a position away from the hand holding the lighter, and therefore safety at the time of igniting fireworks or a stove increases. Further, since the nozzle can be retracted and stored inside the windshield after use, portability is not impaired.

[0006]

According to the present invention, the normal use mode and the remote ignition mode can be selectively used by retracting the nozzle from the windshield, and the nozzle can be stored inside the windshield after use. In addition, the usage mode can be diversified without impairing the portability which is the original function of the pocket lighter.
