BACKGROUND OF THE INVENTION
The present invention relates to an ignition mechanism in a lighter using hexane-based fuel such as petroleum or naphtha, liquid such as alcohol, and liquefied petroleum gas as fuel.
[0002]
[Prior art]
The fuel in the fuel rod is guided to the fuel discharge portion provided above the fuel rod, and the rotary file that is rotatably supported in the vicinity of the fuel discharge portion and the ignition that is energized by the file surface formed on the outer periphery of the rotary file. A lighter is mainly provided which is made of stone and ignites liquid fuel or liquefied petroleum gas discharged from a combustion section on a spark generated by rubbing the ignition stone by rotation of a rotating file to form a flame.
[0003]
This type of lighter has a filed blade on the outer peripheral surface of the rotating file, and there is a risk of damaging the finger when operated directly with a finger. In some cases, rotation auxiliary wheels having a diameter larger than the outer diameter of the rotating file are provided on both side surfaces of the rotating file so that the finger does not directly contact the rotating file.
[0004]
In addition, the side surface of the rotating file is divided, and an engaging piece made of an elastic body is brought into contact with the divided portion, and the file wheel is rotated by a combination of a pinion and a rack gear or a ratchet mechanism, thereby rotating the outer periphery of the file wheel. There are also provided those that ignite by rubbing the filed surface and the ignition stone formed on, and a cap that covers the fuel discharge part of the combustion part in conjunction with the gear mechanism and the ratchet mechanism equipped in the file rotation mechanism. ing.
[0005]
[Problems to be solved by the invention]
The lighter, which consists of a means for igniting by the ignition stone friction caused by the rotation of the file wheel and the structure of the fuel discharge part that ignites and burns the ignition spark, is the simplest mechanism. As a result, normal ignition combustion cannot be obtained during ignition combustion, and there is a problem in safety. Therefore, when the lighter is not used, safety measures such as a cap covering the fuel discharge part of the combustion part are required.
[0006]
However, when the cap that covers the fuel discharge part of the combustion part is configured, the file wheel has the file direction of the file blade, so it is necessary to always keep the rotation direction in a constant direction. On the contrary, the cap that covers the fuel discharge part is When the combustion part that opens at a certain angle is released and the cap covers the combustion part, it is necessary to rotate it in the direction opposite to the opening direction.Therefore, the conventional lighter has to be divided on the side of the file car or on the side of the file car. A complicated structure, such as a combination of gears with a ratchet mechanism, has led to increased costs.
[0007]
Furthermore, in a lighter made of petroleum fuel such as benzene or hexane or liquid fuel such as alcohol, the fuel is vaporized at room temperature when the fuel discharge part is released. It was necessary to suppress vaporization while keeping the discharge part substantially airtight.
[0008]
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a lighter ignition combustion mechanism with a simple mechanism and high safety.
[0009]

Extinguish the formed flame. The rotation direction of the file wheel is always required to rotate in a constant direction because of the direction of the cutting line of the file. However, if the auxiliary operation member is rotated in the opposite direction to that of the ignition operation, the file wheel is the outer periphery of the file wheel. The structure is configured so that only the auxiliary operation member can rotate freely on the file rotation axis and rotate in the direction opposite to the ignition rotation direction. Therefore, it is possible to seal the cap part of the operation assisting member to the fuel discharge part without dividing the filed car side face or to form a complicated gear, etc., and to reliably extinguish the combustion flame formed from the fuel discharge part. In addition, foreign matters such as foreign matters that cause abnormal combustion can be prevented from entering the fuel discharge section, and the vaporization of the fuel from the fuel discharge section can be suppressed, thereby providing a highly safe lighter with a simple structure.
