DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for driving an ignition file car for a smoking lighter.

[0002]

2. Description of the Related Art At present, two main types of smoking lighters are those having a mechanical ignition mechanism using a firing file vehicle and those having an electronic ignition mechanism using a piezo element. Among them, a mechanical ignition mechanism arranges an ignition file wheel rotatably near a burner nozzle or an ignition core that discharges fuel, and rubs the ignition stone by rotating the ignition file wheel with a finger to ignite sparks. Generate and ignite.

[0003]

The ignition operation of a smoking lighter using a conventional mechanical ignition mechanism involves rotating a firing file wheel with the thumb to generate sparks and rotating the firing file wheel. This requires a series of operations in which the thumb is slid as it is and the operating lever of the burner valve is pushed down to ignite. However, it is surprisingly necessary to rotate the file car so quickly that a spark is generated, and the ignition often fails due to insufficient rotation. Further, unless the thumb rotating the ignition file wheel is slid and the operating lever of the burner valve is operated in a timely manner, there is a possibility that the timing of the generation of the spark and the timing of the ejection of the gas are shifted and the ignition fails.

[0004] If the ignition file is rotated many times due to a failure in ignition, the finger hurts, and if the friction is repeated many times, the ignition file becomes hot and there is a risk of burns. In view of the above, the present invention has an object to provide an ignition file driving apparatus having a new structure.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a driving apparatus for driving an ignition file of a smoking lighter, comprising: a crank mechanism for rotating the ignition file wheel; An operating mechanism that rotates in a fixed direction, and a structure that generates a spark by vigorously rotating the ignition file wheel by the resilient force of the operation mechanism, the human hand does not turn the ignition file wheel, but the operation mechanism It is used to generate resilience.

The crank mechanism in the driving device for the ignition file wheel includes a rotating plate attached to a side surface of the ignition file wheel or for rotating the ignition file wheel as a gear meshing with the ignition file wheel, and a side surface of the rotating plate. And a crankshaft having one end connected to a protruding crankpin. In this case, the operating mechanism accommodates the other end of the crankshaft so as to be vertically slidable and is urged upward, and the vertically moving cylinder is housed therein by being pushed down. An elastic body that accumulates an elastic force that urges the other end of the crankshaft downward,
And a trigger structure for releasing the elasticity of the elastic body when the vertical moving cylinder is pressed down to a predetermined position. According to this, as in the case of an electronic ignition mechanism using a piezo element, ignition is performed as long as the vertical moving cylinder is pressed down with a finger.

[0007] Such an ignition file vehicle, a crank mechanism and an operating mechanism are integrally assembled into one housing to form a unit, so that the unit can be assembled and exchanged with a smoking lighter by a unit exchange type. Yes, even laymen can easily work. Further, in the smoking lighter in this case, the vertical movement guide groove of the pillar provided in the lighter body includes a pusher member for pushing down the vertically moving cylinder of the assembled ignition file driving unit and operating the burner valve operating lever.
