Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ignition mechanism for a lighter for smoking or the like, and particularly to an inexpensive ignition mechanism that can be easily and reliably ignited by a single operation without soiling a fingertip. It is related to.

[0002]

2. Description of the Related Art The following has already been used as an ignition mechanism in a lighter. (1) Piezoelectric Ignition Mechanism The gas emitted from the nozzle is ignited by applying a shock to the piezoelectric element to cause electric discharge between the discharge electrode and the tip of the nozzle. (2) Electric Ignition Mechanism The gas discharged from the nozzle is ignited by discharging the charge stored in the capacitor from the battery to the step-up transformer. (3) Flint Type Ignition Mechanism A rotary file and a igniting stone pressed against the rotary file by the force of a spring are provided, and the rotary file is rotated to generate a spark, which is emitted from the nozzle. It is designed to ignite gas

[0003]

The above-mentioned conventional piezoelectric ignition mechanism and electric ignition mechanism are preferable in that ignition can be performed by a single operation, but the timing of vaporized gas release Since it is difficult to set the discharge state and the discharge state, defective products are likely to occur in the manufacturing process, resulting in a poor yield. Further, in these ignition mechanisms, since expensive components such as piezoelectric elements or batteries, capacitors, step-up transformers are used in addition to the conductive material, there is a problem that the manufacturing cost increases. On the other hand, the flint type ignition mechanism has a drawback that it requires two operations of rotating the rotating file and pressing the operation lever at the time of ignition. Further, since the flint type ignition mechanism is designed so that the rotary file is directly rotated by the user's finger, the unevenness of the peripheral surface of the rotary file causes pain on the user's fingertip, and further the rotary file is rotated. There is also a problem that the fingertips and clothes are contaminated by the residual powder of sparks attached to the. The present invention has been made to solve the above problems, and to provide an inexpensive ignition mechanism that can easily and reliably ignite a single operation without soiling the fingertip.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above problems by improving a flint type ignition mechanism that can be manufactured at low cost. That is, the present invention is provided with a rotary file and a igniting stone that presses against the rotary file by the force of a spring, and by rotating the rotary file to generate a spark, the fuel discharged from the nozzle In the ignition mechanism adapted to ignite, a gear is provided coaxially with the rotary file on at least one side of the rotary file,
The operating member is pivotally supported in the vicinity of the gear so as to be tiltable in the direction of moving toward and away from the gear and vertically movable, and the operating member is provided with at least one claw portion corresponding to the tooth portion of the gear. Is integrally formed with the operating member via a hinge part so as to be tiltable in the direction of moving toward and away from the gear, and a coil spring is attached between the lower end of the operating member and the lighter body, and the coil spring keeps the operating member in the gear direction at all times. (EN) An ignition mechanism in a lighter, characterized in that an operating member and a nozzle elevating lever are associated with each other so that the nozzle is raised via the nozzle elevating lever when the operating member is pushed down. It is a thing.

In order to constantly press the operating member in the direction of the gear by the coil spring, it is desirable that the lower end of the operating member be an inclined surface that is inclined so that the gear side becomes higher.

In order to constantly press the operating member in the gear direction by the coil spring, it is desirable that the center of the coil spring is located farther from the gear than the center of the support shaft of the operating member. In the present specification including the claims, the "supporting shaft of the operating member" includes not only the supporting shaft protruding from the operating member but also the supporting shaft for the operating member protruding from the lighter body.

[0007]

[Ignition Mechanism of Claim 1] In the ignition mechanism of Claim 1, the lighter is ignited by a single action of simply pushing down the operating member with a finger. The operating member is tiltable in the direction of coming in and out of contact with the gear of the rotating file and is constantly pressed in the direction of the gear by a coil spring mounted between the lower end of the operating member and the lighter body. When the operation member is pushed down against the force of
The claw portion integrally formed with the operating member via the hinge portion smoothly engages with the tooth portion of the gear of the rotating file, and rotates the rotating file via the gear. At this time, since the claw portion can be tilted in the direction toward and away from the gear by the hinge portion, the rotation angle of the gear during each ignition operation is always constant, resulting in stable ignition performance. Incidentally, when the rotation angle of the gear during each ignition operation is not constant, the engagement between the claw portion and the tooth portion of the gear during the next ignition operation becomes insufficient or the engagement position becomes inappropriate, Therefore, the lighter may not be ignited or may be difficult to ignite. When the rotating file rotates, friction is generated between the rotating file and the igniting stone that is pressed against the rotating file by the force of the spring, and a spark is generated. On the other hand, when the operating member is pushed down, the nozzle is raised via the nozzle lifting lever, and the fuel is discharged from the nozzle. Therefore, the fuel discharged from the nozzle is ignited by the spark. After ignition, when the finger is released from the operating member, the operating member is pushed upward by the coil spring attached between the lower end of the operating member and the lighter body. At this time, the operating member is constantly pressed by the coil spring in the direction of the gear, but the operating member can be tilted in the direction of moving toward and away from the gear, and the claw portion of the operating member moves toward and away from the gear by the hinge. Since the claw portion of the operating member can smoothly ride over the tooth portion of the gear, it returns to the original position above the gear. Also,
When the operating member is pushed upward by the coil spring in this way, the nozzle elevating lever is released from being pushed down by the operating member, so that the nozzle is lowered to its original position by the return spring and the fuel discharge is stopped. Therefore,
The lighter goes out. As a result, the lighter returns to the state before ignition.

[Ignition mechanism according to claim 2] When the lower end of the operating member is inclined so that the gear side becomes higher, the coil spring makes the lower end surface of the operating member parallel to the upper end surface of the coil spring. Since the desired force is exerted on the operating member, the operating member is always preferably pressed in the gear direction.

[Ignition Mechanism of Claim 3] When the center of the coil spring is located farther from the gear than the center of the spindle of the operating member, the coil spring rotates the operating member around the spindle. Since it is pushed up in the direction of tilting, the operating member is always preferably pressed in the gear direction.
