[Prior art]

 Conventionally, the structure of a piezoelectric ignition lighter is as shown in FIG. 5, which stores liquefied petroleum gas. Page (2) Lighter body 21 made of synthetic resin or the like equipped with a fuel tank 20, and vaporized gas produced by the liquefied petroleum gas. Gas discharge nozzle 22 having a structure capable of discharging gas, a lever portion 23 for restricting gas discharge, and a spark discharge between the gas discharge nozzle 22 and an electrode 24 provided in the vicinity thereof by hitting a piezoelectric element. It is composed of a piezoelectric unit 25 for generating electrical energy that causes the electric power generation, and an operation button 26 for operating the piezoelectric unit 25.When igniting, when the operation button 26 is pressed, the gas release regulating lever 23 is released. The gas is discharged by rotating, and at the same time, the projection 27 provided on the lower portion of the operation button 26 presses the hammer via the movable body 28 of the piezoelectric unit 25, and the hammering operation of the hammer causes the gas discharge nozzle 22 to move. And the electrode 24 Causing a spark discharge causes ignition is flammable release gas by sparks. Further, when extinguishing the fire, when the finger is released from the operation button 26, the lever portion 23 is rotated to the original position and the discharge of gas is stopped, so that the fire is extinguished.

However, in the conventional piezoelectric ignition lighter, the protrusion 27 of the operation button 26 directly presses the top of the movable body 28 in the piezoelectric unit 25 at the time of ignition, and electric energy is generated by a momentary impact of a hammer. As shown in FIG. 6, the operating dimension of the movable body 28 required for the momentary impact requires about 5 mm in the vertical direction around the rotation support shaft of the normal operation button 26, so that the piezoelectric unit ( Normally, the vertical size of 35 mm to 40 mm) goes deep into the fuel tank 20 of the lighter body 21, so the volume of the tank 20 decreases and the fuel capacity decreases accordingly, and there is a problem of piezoelectric ignition. It was also a factor that prevented the lighter from being downsized.

[Action]

 When the piezoelectric ignition lighter according to the present invention is ignited, the lever portion that restricts the gas release is rotated by pressing the operation button, and the lever action of this lever causes the vaporized gas to be released from the gas release nozzle. Further, by rotating the operation button, the hammer portion is pressed through the movable body of the piezoelectric unit to strike the piezoelectric element, and between the gas discharge nozzle linked to the piezoelectric unit and the electrode provided in the vicinity of this nozzle. A spark discharge is generated to ignite and ignite the released gas. In this case, since the hammer pressing part for operating the hammer part is set lower than the top part of the hammer part of the piezoelectric unit, the piezoelectric unit can be installed above the lighter body. It does not go deep into the tank, so the volume of the tank can be greatly increased compared to that of the conventional page (4).

【Example】

 Next, an embodiment of the piezoelectric ignition unit according to the present invention will be described with reference to the drawings. A lighter body 2 having a fuel tank 1 for containing liquefied petroleum gas, and a gas having a configuration capable of vaporizing and releasing liquefied petroleum gas. A discharge nozzle 3, a lever portion 4 for restricting the discharge of gas, and a piezoelectric element are struck to generate electrical energy between the gas discharge nozzle 3 and an electrode 5 provided in the vicinity of the discharge electrode 3 to generate electrical discharge. In a piezoelectric ignition lighter composed of a piezoelectric unit 6 and an operation button 7 for operating the piezoelectric unit 6, the lighter body 2 is made of a resin such as hard plastic, and a liquefied petroleum gas fuel is used at the bottom. The tank 1 is provided.

It pivots as a fulcrum, and the lever action of this pivots up the gas discharge nozzle 3 locked to the lever portion 4 to enable gas discharge. The surface resistance value of the operation button 7 is preferably 10 KΩ to 40 KΩ, and according to the above value, the spark discharge generated between the electrode 5 and the gas discharge nozzle 3 becomes stable.

Next, reference numeral 17 is a stepped portion for supporting the hammer pressing portion 15 in the operation button 7 provided on the upper portion of the piezoelectric unit 6 and on the side portion of the movable body 18 for hammer operation.

In this case, since the step portion 17 of the hammer pressing portion 15 for operating the movable body 18 for hammer operation is set to be lower than the top of the movable body 18 of the piezoelectric unit 6, the piezoelectric unit 6 includes the lighter main body 2 Since it can be installed on the upper part of the fuel tank 1, the piezoelectric unit 6 does not go deep into the fuel tank 1 in the assembled state, and therefore the tank volume can be greatly increased compared to the conventional one. Also, in the case where the movable body 18 is capped with the stepped portion 17 and is capped, the ignition is carried out by the same operation as in the above embodiment, and even in this case, the hammer for operating the movable body 18 for hammer operation is used. Since the step portion 17 on page 15 (6) of the pressing portion is set lower than the top portion of the movable body 18 of the piezoelectric unit 6, the piezoelectric unit 6 can be installed on the upper portion of the lighter main body 2, so that it is in the assembled state. Since the piezoelectric unit 6 does not go deep into the fuel tank 1, the tank volume can be increased as compared with the conventional one.

Unlike the one hit, the piezoelectric unit does not penetrate deeply into the fuel tank of the lighter body, so the volume of the tank does not decrease and the fuel capacity does not decrease correspondingly, but rather increases the capacity. There is a special effect that can be achieved, and a unique effect that can be achieved by making the piezoelectric ignition lighter smaller. By providing the movable body for the hammer operation of the piezoelectric unit with the step portion which the hammer pressing portion of the operation button can abut, the number of components can be reduced and the assembling can be facilitated.
