Description

[Detailed Description of the Invention] The present invention relates to a high-voltage generator that applies an impact to a piezoelectric element to obtain a high voltage, and uses the resulting spark to ignite gas in a lighter or the like.

Conventionally, in this type of high voltage generator, impact energy is stored in an impactor by a pressing operation of an operating body, and by continuing to press the operating body, the impactor is rapidly moved by a cam mechanism or the like.

In other words, most of the configurations were based on a series of unidirectional pressing operations.

However, in this type of device, when releasing the impactor in which energy is stored, it feels very difficult to operate, which is a major drawback in pocket lighters and the like.

Therefore, the present invention proposes a concrete structure that eliminates the above-mentioned drawbacks and allows reliable and easy operation by providing separate means for storing impact energy in the impactor and means for releasing it.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a storage body that stores a piezoelectric element 2;
On the end face of the piezoelectric element 2, a stopper 3 that directly receives an impact and a support 4 that holds and fixes the piezoelectric element 2 are arranged.

At the center of the piezoelectric element 2, an intermediate terminal 5 and a high-voltage wire 6 are disposed for extracting electricity.

Further, in the storage body 1, an impactor 7 or an impact spring 8 is arranged so as to abut against the pad 3 and be pressed by an impact spring 8.

Furthermore, an impactor pin 10 protrudes from the impactor 7.

11 is a lever having a tapered portion 11a at the tip;
This lever 11 is built into the storage body 1 in such a manner that it is pressed in the direction of arrow B by a return spring 9 (here, the stopper is omitted because it is not directly related to the present invention).

Further, an L-shaped cam portion 1a is provided on one side of the storage body 1, and a lever 11 is attached to the L-shaped cam g[a].
A tapered portion 11a of the tip is located.

Now, when the lever 11 is pressed in the direction of arrow A against the bias of the return spring 9 from the state shown in FIGS.
1 comes into contact with the impactor pin 10, causing the impactor 7 to move in the direction of arrow A against the impact spring 8.

When the impactor pin 10 eventually reaches the groove of the L-shaped cam portion 1a of the storage body 1, the pin 10 is moved by the elastic energy of the tapered portion 11a of the lever 11 and the impact spring 8 as shown in FIG. It enters the groove of the L-shaped cam portion 1a as shown in FIG.

That is, the impactor 7 is held in a state in which impact energy is stored by the energy of the impact spring 8.

Here, when the pressing force of the lever 11 is removed, the lever 11 returns to its original state due to the energy of the return spring 9.

Thereafter, when the impactor pin 10 is pressed from the lateral force direction F as shown in FIG.
Since the impactor 7 comes off the groove part a and applies an impact to the piezoelectric element 2 via the pad 3, a high voltage can be obtained.

Here, the means for pressing the impactor pin 10 from the lateral force direction F may be installed in a device (for example, a lighter) or may be installed in the mechanical part of the present invention, and there are no particular restrictions. .

The high voltage generator of the present invention is constructed as described above, and by configuring the means for storing impact energy in the impactor and the means for releasing it separately, the impactor with stored energy can be released. In this case, it can be operated with a very light operating force, and it can be operated reliably with a simple structure, so it has great practical value when used in pocket lighters, etc.
