Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high voltage generator used to generate a high voltage by applying an impact to a piezoelectric element, and to cause a spark discharge from the high voltage to ignite gas or the like.

As shown in FIG. 1, in a conventional high voltage generator, a cylindrical operator 4 is slidably inserted back and forth into an outer storage body 2 containing a piezoelectric element unit 1 via a return spring 3. An impactor 6 having a pin 5 is slidably fitted into the child 4 via an impact spring 7, and the pin 5 of the impactor 6
is fitted into a cam hole 8 provided in the operator 4 and a single-shaped cam hole 9 in the outer storage body 2.

With this configuration, when the operator 4 is pressed in the direction of arrow A,
The pin 5 of the impactor 6 that engages with the stepped part of the single-shaped cam hole 9 accumulates impact energy due to the compression of the impact spring 7, and eventually the pin 5 becomes 1 due to the inclined part of the cam hole 8 provided in the operator 4. When the engagement with the stepped portion of the cam hole 9 is released, the impactor 6 slides toward the piezoelectric element unit 1 due to the impact energy caused by the compression of the impact spring 7, applying an impact to the piezoelectric element unit 1, and causing a high rise. It was used to obtain voltage.

Furthermore, when the operating force on the operator 4 is released, the operator 4 and impactor 6 slide back in the direction opposite to the direction of arrow A due to the return spring 3, and the pin 5 of the impactor 6 is moved back to the single-shaped cam. Hole 9
It was designed to be engaged with the step part in preparation for the next operation.

In this way, in the conventional high voltage generator, the operator 4
During the pressing operation, an impact is applied to the piezoelectric element unit 1 by the impactor 6, thereby generating a high voltage.

In pocket lighters that use such high voltage generators, ignition can be ensured by delaying the timing at which the high voltage is generated as much as possible from the timing at which the gas is injected, and the pocket lighter itself is not a luxury item. However, the above-mentioned conventional high-voltage generator could not satisfy the above-mentioned demands.

The present invention aims to eliminate the above-mentioned conventional drawbacks, ensure ignition, and provide a new operating method and operating feel.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.

Reference numeral 10 denotes a case-like storage body with an open top surface, and a piezoelectric element unit 11 is fixedly stored in one end of the interior of the storage body 10, and an impactor 12 and this impactor 1 are slidably housed.
Impact spring 1 that always urges 2 toward the piezoelectric element unit 11
3 is stored.

Further, a pin 14 is provided on the upper surface of the impactor 12 so as to protrude upward, and this pin 14 is connected to the storage body 10.
It fits into a single-shaped cam hole 16 of a cam plate 15 that is placed on the top surface of the cam plate 15.

The upper surface of this cam plate 15 has a bent piece 1 provided on the storage body 10.
A plate-shaped operating lever 19 slidably held by 7.18 is disposed, and one end of this operating lever 19 is provided with a downwardly bent portion 20, and this bent portion 20 and the storage body 1
A return spring 2 is provided between the outer end surface on the piezoelectric element unit side of 0 and
1 is arranged, and this operating lever 19 is always biased toward the bending portion 20 side.

A deformed pentagonal cam notch or cam hole 22 is provided on the other end side of the operating lever 19, and the above-mentioned impactor 1
The second pin 14 is located within this cam notch or cam hole 22.

In such a configuration, the operating lever 19 is returned to the spring 2.
1, the pin 14 of the impactor 12 is pushed into the cam notch or cam hole 2 of the operating lever 19.
2 and slides in the direction A while receiving rotational torque in the direction of inclination.

Due to this sliding, the impactor 12 moves away from the piezoelectric element unit 11 while elastically contracting the impact spring 13.

If the operating lever 19 is further pressed, the pin 14 will eventually fall into the stepped portion 16a of the single-shaped cam hole 16 of the cam plate 15.

The pressing operation of the operating lever 19 is now stopped, and the fourth
As shown in the figure, impact energy is applied to the impactor 12 due to the elastic contraction of the impact spring 13, and the impactor 12 is held in a held state by the depression of the stepped portion 16a of the pin 14.

If you release the pressing force on the operating lever 19 in this situation,
The operating lever 19 starts sliding return due to the return spring 21, and the cam notch or cam hole 22 of the operating lever 19
When the inclined portion 22b on the other end hits the pin 14 and pushes out the pin 14 from the stepped portion 16a of the single-shaped cam hole 16, the impactor 1
2 is no longer held, and the impactor 12 slides forcefully toward the piezoelectric element unit 11 due to the accumulated energy of the impact spring 13, collides with the piezoelectric element unit 11, and generates a high voltage in the piezoelectric element unit 11.

Along with this operation, the operating lever 19 slides back and prepares for the next operation.

As described above, since the high voltage generator of the present invention is barked, the pressing operation of the operating lever is completed and the high voltage is generated in the piezoelectric element unit by the impact from the impactor during the period of sliding return, so the pocket lighter It has the advantage of being able to discharge sparks in a state where sufficient gas is injected, increasing ignition efficiency, and meeting the user's needs as it differs from the conventional operating sensation. It has great practical value.
