ってきた。Conventional structure and its problems Recently, in the cigarette industry, an increasing number of manufacturers are adopting the piezoelectric ignition method for disposable lighters.Of course, it is necessary to obtain the best ignition method with a low-priced product, and it is necessary to make it more reliable. There is a strong demand for improving the ignition energy in order to ignite a lighter, and there is also an attempt to take advantage of the low price and adopt the high voltage generator developed for disposable lighters for general lighters. There is a growing trend to do so.

６も元の状態に復帰する。The operation of the high voltage generator having the above-described VC configuration will be explained below. First, install it into the outer case 4.
When the inner case 8 is pressed, the impactor 6 accumulates the impact force due to the impact spring 7, and the impactor 6 accumulates the impact force due to the impact spring 7, and furthermore the impactor 6 accumulates the impact force from the impact spring 7, and the impactor 6 accumulates the impact force due to the impact spring 7. When the case 8 is pressed, the impactor pin 9 of the impactor 6 is disengaged from the cam of the outer case 4 by the cam formed in the inner case 8, and therefore the impactor 6 becomes piezoelectric due to the accumulated impact force. An impact is applied to the element 1, and a high voltage is generated from the piezoelectric element 1. Then, when the pressing force is released, the inner case 8 returns to its original state due to the return spring 1o, and accordingly, the impactor 6 also returns to its original state.

As the material for the outer case 4, a polyamide-based molding material was used, but as is well known, polyamide-based resin is
In terms of moisture resistance, it is extremely inferior to other plastic resin materials, so if it is left in a high-temperature flame or a humid atmosphere, the outer case 4 will break, the wire resistance will drop sharply, and the outer case 4 and piezoelectric The adhesive force with the element 1 is also weakened, and the resonance phenomenon between the piezoelectric element 1 and the outer case 4 is also alleviated.As a result, the initial discharge current waveform shown in Fig. 3 changes to the discharge time shown in Fig. 2. The waveform is short and the discharge energy shown by the area of the shaded area is also low.Objective of the Invention δ The present invention has been devised to eliminate the problems of the conventional RP1 as described above, and by improving moisture resistance. SUMMARY OF THE INVENTION The object of the present invention is to provide a high voltage generator that can sustain efficient discharge energy even after being left in a high temperature and humid atmosphere. High voltage generator is
The material of the outer case containing the piezoelectric element is a polycarbonate resin material containing 420 to 40% glass fiber as a reinforcing material, and an epoxy resin is used as the impregnated adhesive for insulating the piezoelectric element. In this case, the adhesive strength of the adhesive that reaches the piezoelectric element and the outer case is almost the same, and the piezoelectric element that is impacted by the impactor resonates with the outer case, and the resonance with the outer case induces vibrations in the piezoelectric element. In addition, since the outer case is made of polycarbonate resin, which has excellent moisture resistance, the same piezoelectric element resonance phenomenon as the initial one can be maintained even after being left in a hot and humid atmosphere. becomes.

In the present invention, the outer case 4 is made of a polycarbonate resin material containing glass fiber as a reinforcing material, and an epoxy resin is used as the impregnated adhesive 5 for insulating the piezoelectric element.

ような効率の良い振動現象が持続するものである。In the high voltage generator of the present invention configured in this manner, the adhesive 6 can have approximately the same adhesive force between the piezoelectric element 1 and the outer case 4, and the impact force applied from the impactor 6 can be reduced. The piezoelectric element 1 resonates with the outer case 4, and vibration is efficiently induced in the piezoelectric element 1 due to the resonance with the outer case 4. As shown in the discharge current waveform shown in Fig. 3, the discharge time T2 is also longer. At the same time, several vibration waveforms are generated with certainty, and the discharge energy (area of the shaded area) also increases.Since the outer case 4 also has excellent moisture resistance, the discharge waveform due to a decrease in adhesive strength, etc. The above-mentioned efficient vibration phenomenon continues without any change.

る。Here, if the reinforcing glass fiber contained in the polycarbonate resin material constituting the outer case 4 is less than 20%, the piezoelectric element 1 of the outer case 4 has a small amount of reinforcing glass fiber.
There are not many irregularities on the adhesion surface, so the adhesion strength does not improve much, and the above-mentioned resonance phenomenon cannot be obtained. On the other hand, if the reinforcing glass fiber content exceeds 40%, molding becomes impossible. Therefore, in the present invention, a polycarbonate resin material containing 20 to 40% of reinforcing glass fiber is used as the outer case 4, and the characteristics shown in FIG. When silicone resin was used as the O adhesive 5 in the case, the adhesiveness of the silicone adhesive was almost non-existent, and no resonance phenomenon was obtained between the outer case 4 and the discharge current waveform. Furthermore, if the outer case 4i is made of ABS resin material, polypropylene resin material, etc., and epoxy resin or silicone resin is used as the adhesive 6, no combination of 2
It was not possible to obtain better results than the characteristics shown in the figure. That is, in the present invention, a resonance phenomenon occurs when the material of the outer case 4 and the thickness 1 of the adhesive 5 are combined as shown in the above embodiment, and the above-mentioned effects cannot be obtained by using either one or other combinations. be. 1. Among the above combinations, when polyamide resin material is used, initially it can obtain the characteristics shown in Figure 3, similar to polycarbonate resin material, but after being left in a hot and humid atmosphere, the characteristics approach those shown in Figure 2. This is not desirable in practice. FIG. 4 Q shows the changes in Jl and 4j properties of polycarbonate and polyamide resin materials when left in humidity. Polycarbonate 1. hardly changes and can maintain its initial properties.
