Abstract

PURPOSE:To enable the discharge time to be taken long, by a method wherein a conductive resin body is arranged between a piezoelectric element to be struck by an impactor via butting metal and a receiver metal, in the titled device for gas ignition. CONSTITUTION:A conductive resin body 10 is placed between the receiver metal 3 and the piezoelectric element 4. This construction produces the integral oscillation of the element 4 with the resin body 10 because the impact energy from an impactor 6 is received by the element 4 and the resin body 10 which has elasticity. Therefore, the ignition performance improves with a long discharge time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high voltage generator for gas ignition used in cigarette lighters, gas appliances, and the like.

2. Description of the Related Art Conventionally, this type of high voltage generator has had a configuration as shown in FIG. In FIG. 3, reference numeral 1 denotes an outer box, and a pad 2 and a receiver are provided with a pad 3 and a piezoelectric element 4 located therebetween. Further, 5 is an inner box, which is provided with an impactor 6, an impact bottle 7, and an impact spring 8, and is slidably fitted into the outer box 1. A return spring 9 is housed on the mating side of the inner box 5 of the outer box 1.

When the end surface 5a of the inner box 5 is pressed to the left in FIG.
Since it is engaged with, it presses the impact spring 8 and the return spring 9. In particular, the impact spring 8 is in a state where impact energy is stored. When further pressure is applied and the inner box 5 moves by a certain stroke, the impact bottle 7 opens a window portion (not shown) having a tapered portion provided on the inner box 5 facing the cam portion of the outer box 1.
is released from the cam section. Therefore, the compressed impact spring 8 is also released, and the stored impact energy is applied by the impactor 6 to the piezoelectric element 4 via the pad 2, generating a high voltage. At this time, the gold plate 3 serves as an impact receiver and a ground, and the high voltage is applied to the end face 5a1 of the inner box 5 through the pad 2, impactor 7, and impact spring 8. : Provided hole 5
It is taken out from b. After that, when the pressure on the inner box 5 is released, the inner box 5 is returned to its original position by the compressed return spring 9, and at the same time, the released impact bottle 7 is again engaged with the cam part provided on the outer box 1. be stopped.

Problems to be Solved by the Invention In the conventional configuration described above, when the impact energy from the impactor 6 is applied to the piezoelectric element 4 via the pad 2, the impact is directly applied to the metal pad 3 with low elasticity. As a result, the voltage waveform generated from the piezoelectric element 4 hardly oscillated, making it impossible to obtain a long discharge time, and as a result, the ignition performance was also insufficient. The discharge current waveform is shown in FIG.

Means for Solving the Problems In order to solve the above problems, the high voltage generator of the present invention includes:
A conductive resin body is disposed between the piezoelectric element, which is struck by the impactor through the metal, and the metal.

Effect: According to the above configuration, when impact energy is applied to the piezoelectric element, the piezoelectric element is integrated with the conductive resin body! lJ
Therefore, it becomes possible to take a longer discharge time.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 is a cross-sectional view of a high voltage generator according to an embodiment of the present invention, and the same components as those shown in FIG. 3 are given the same reference numerals and their explanations will be omitted. In FIG. 1, reference numeral 10 denotes a conductive resin body, and this conductive resin body 10 is installed between the metal plate 3 and the piezoelectric element 4.

Hereinafter, the effects of the above configuration will be explained.

Since the piezoelectric element 4 and the elastic conductive resin body 10 receive the impact energy from the impactor 6, the piezoelectric element and the conductive resin body 10 vibrate together. Therefore, the discharge current of the piezoelectric element 4 is as shown in Fig. 2, and the discharge time is long (,
Improves ignition performance.

Effects of the Invention As described above, according to the present invention, since the conductive resin body is disposed between the piezoelectric element and the gold plate, the impact energy from the impactor is transferred between the piezoelectric element and the elastic conductive resin body. Since these components vibrate together, the discharge time becomes longer and the ignition performance can be greatly improved.
