Description

[Detailed description of the invention] The present invention relates to a high voltage generator that generates high voltage by applying an impact to a piezoelectric element, and more specifically, it provides a device that is easy to assemble and has excellent cost and characteristics. It is something to do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A high voltage generator according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 is a piezoelectric element, and a conductive receiver 3 is disposed at one end of the piezoelectric element 1 via a spacer 2.
A conductive hit body 4 is disposed at the other end via a conductive piece 6 which also serves as a spacer, and this piezoelectric element 1 connects the discharge terminal of the conductive receiver 3 to the outside at the bottom of the outer case 5. It is recessed and stored so that it is exposed.

Reference numeral 8 denotes an inner case fitted into the outer case 5. Inside the inner case 8, there is provided a hammer 7 for striking the conductive hit body 4 of the piezoelectric element 1 and applying an impact to the piezoelectric element 1.
and a hammer spring 9 for applying a striking force to the hammer 7.

A locking pin 7a is attached to the hammer 7, and the locking pin 7a locks into an L-shaped cam hole 5b provided in the outer case 5 and a cam hole 8a in the inner case 8.

Reference numeral 10 denotes a return spring that urges the inner case 8 in a direction to protrude from the outer case 5, and the inner case 8 fitted into the outer case 5 is pushed back by the return spring 10.

The conductive piece 6 is interposed between the piezoelectric element 1 and the conductive hit object 4, and one end thereof has a flat part 6a which also serves as a spacer, and the other end 6b has a flat part 6a which also serves as a spacer. It is exposed through the hole 5C at the fifth end and reaches one end of a threaded portion 5a formed on the outer periphery of one end of the outer case 5.

The hole 5C also serves as an injection hole for the resin that fixes the element 1, and the conductive piece 6 is fitted into the narrow hole 5d and rotated 90 degrees to prevent removal.

That is, the high voltage generator according to the present invention has the inner case 8
By pushing the locking pin 7a of the hammer 7 in the direction of pushing it into the outer case 5, the locking pin 7a of the hammer 7 is released from the cam hole 5b of the outer case 5.
As a result, the hammer 7 hits the conductive hit object 4 of the piezoelectric element 1 by the spring force of the hammer spring 9, and a high voltage is generated from the piezoelectric element 1.

This high voltage can be extracted from between the conductive receiver 3 and the conductive piece 6.

According to the structure of the present invention, one end 6a of the conductive piece 6
is interposed between the conductive hit object 4 and the piezoelectric element 1, making assembly extremely easy, and grounding can be done by having one end of the conductive piece 6 reach one end of the threaded part 5a. This makes it easy to install on various gas appliances, etc.
