The same parts as those in FIG. 1 are designated by the same reference numerals to simplify the description. In the present embodiment, as shown in FIGS. 4 and 5, the volume of the space portion of the piezoelectric element housing portion 12a of the outer case 12 is set to 2.5 or more when the volume of the piezoelectric element 3 is set to 1. Part of the impact receiver 2 and the piezoelectric element 3 are housed, and in this state, the base metal 4 is inserted,
With the pressure applied by the pressure spacer 5, the highly adhesive epoxy resin 13 is filled in the outer peripheral portion of the piezoelectric element 3 in the space of the piezoelectric element storage portion 12a and integrally fixed.
このように構成された本実施例の高電圧発生装置によれ

与えられた衝撃力で圧電素子３は高接着性エポキシ樹脂
１３との共振により効率よく振動を誘起する。つまり、
第６図に示す放電電流波形のように振動波形数が多く、
放電時間Ｔ2も長くなり、従って放電エネルギー（斜線
部面積）も高くなるものである。According to the high voltage generator of this embodiment having such a structure, the piezoelectric element 3 is firmly adhered and coated with the high adhesive epoxy resin 13, and these are integrated so that the piezoelectric element 3 is provided by the hammer 9. The impact force causes the piezoelectric element 3 to efficiently induce vibration due to resonance with the highly adhesive epoxy resin 13. That is,
There are many vibration waveforms like the discharge current waveform shown in FIG.
The discharge time T 2 also becomes long, and therefore the discharge energy (hatched area) also becomes high.
ここで、外ケース１２の圧電素子用収納部１２ａの空間
部の体積を圧電素子３の体積の２．５倍より小さくする
と、高接着性エポキシ樹脂１３による圧電素子３の接着
保持強度が低下する等の理由により振動波形数が少な
く、放電時間も短く、放電エネルギーの小さいものとな
るとともに、圧電素子３自体の耐久性能の低いものとな
るのであった。Here, if the volume of the space of the piezoelectric element housing portion 12a of the outer case 12 is made smaller than 2.5 times the volume of the piezoelectric element 3, the adhesive holding strength of the piezoelectric element 3 by the highly adhesive epoxy resin 13 is reduced. Therefore, the number of vibration waveforms is small, the discharge time is short, the discharge energy is small, and the durability of the piezoelectric element 3 itself is low.
次にこの点を第７図を用いて説明する。Next, this point will be described with reference to FIG.
第７図(A)〜(D)の夫々のＸ軸は放電電流、Ｙ軸は放電時
間、各波形は放電電流波形を示している。In each of FIGS. 7A to 7D, the X-axis shows the discharge current, the Y-axis shows the discharge time, and each waveform shows the discharge current waveform.

It shows how many times when the volume of the piezoelectric element 3 is set to 1. Therefore, if (a) is large, the space is large, and a large amount of the highly adhesive epoxy resin 13 is included in the piezoelectric element 3.
Will be filled in the outer periphery of.
次に第７図(A)〜(D)の(b)はハンマ９で何回衝撃を加え
た場合までこの第７図(A)〜(D)の放電電流波形が得られ
るかを示したもので、耐久性能を示すものである。Next, FIGS. 7 (A) to 7 (D), (b), show how many times the hammer 9 gives impact until the discharge current waveforms of FIGS. 7 (A) to 7 (D) can be obtained. It shows durability performance.
つまりハンマ９による衝撃により圧電素子３が割れたり
すると振動回数が急激に減少することとなるので、この
耐久性能を求めているのである。In other words, if the piezoelectric element 3 is cracked by the impact of the hammer 9, the number of vibrations will be sharply reduced, so this durability performance is required.
またこの耐久性能(b)が何回まで維持できれば良品とす
るかの判断基準については、ライターの使用実態を目安
とし、具体的には次のように定めている。The criteria for determining how long the durability performance (b) can be maintained before it becomes a non-defective product is based on the actual usage of the lighter and is specifically set as follows.
タバコ２５本／日×３年（３６５日×３）＝２７，３７
５回 したがって、第７図(A)，(B)では夫々ｂ＝５００，ｂ＝
１０，０００とこの２７，３７５回よりも耐久性能が劣
るので「否」となる。25 cigarettes / day x 3 years (365 days x 3) = 27,37
5 times Therefore, in FIGS. 7A and 7B, b = 500 and b =, respectively.
Since the durability performance is 10,000, which is inferior to the 27,375 times, the result is "No".
また第７図(C)，(D)ではｂ＝１００，０００以上で上記
２７，３７５よりも大であるので「良」となる。Further, in FIGS. 7 (C) and 7 (D), b is 100,000 or more, which is larger than the above-mentioned 27,375, so that it is “good”.
なお１００，０００以上とは１０万回衝撃を加えても
「良」であったものであり、それ以上の試験は中断し
た。It should be noted that 100,000 or more means "good" even after 100,000 impacts, and further tests were stopped.
次に第７図を用いて圧電素子用収納部１２ａの空間部の
体積と放電電流波形について説明する。Next, the volume of the space of the piezoelectric element housing portion 12a and the discharge current waveform will be described with reference to FIG.
まず第７図(A)はａ＝１．２の時、つまり第１図に示し
た従来例の放電電流波形を示したものであり、振動波形
数は３回で、しかも放電時間も短いものとなっている。First, FIG. 7 (A) shows the discharge current waveform of the conventional example shown in FIG. 1 when a = 1.2, the number of vibration waveforms is 3 and the discharge time is short. Has become.
第７図(B)のものはａ＝２．０とした時のもので、これ
であれば振動波形数も６回と多く、しかも放電時間も第
７図(A)の時よりも長くなっている。The one in FIG. 7 (B) is the one when a = 2.0. In this case, the number of vibration waveforms is as many as 6, and the discharge time is longer than that in FIG. 7 (A). ing.
第７図(C)はａ＝２．５で、第４図，第５図に示した本
実施例に示すものの放電電流波形を示している。これは
第６図のごとく振動波形数も１１回と多く、しかも第７
図(C)のごとく第７図(B)のものより放電時間は長くなっ
ている。FIG. 7 (C) shows the discharge current waveform of the one shown in FIGS. 4 and 5 with a = 2.5. As shown in FIG. 6, this has a large number of vibration waveforms of 11 times, and the seventh
As shown in Fig. 7C, the discharge time is longer than that of Fig. 7B.
第７図(D)のものはａ＝３．０の時の放電電流波形を示
し、振動波形数，放電時間とも第７図(C)のものと同様
の結果が得られた。FIG. 7 (D) shows the discharge current waveform when a = 3.0, and the same results as in FIG. 7 (C) were obtained for both the number of vibration waveforms and the discharge time.
それでは次に(a)を第７図(A)から(D)へと大きくすると
上述したように振動波形数が増加するのか、(b)の耐久
性能が向上するのかという理由について説明する。Then, the reason why whether the number of vibration waveforms is increased or the durability performance of (b) is improved by increasing (a) from FIG. 7 (A) to (D) will be explained.
すなわち空間部の体積を、圧電素子３の体積に比較して
大きくすると、そこに充填する高接着性エポキシ樹脂１
３の量を多くすることができるので、その分圧電素子３
を外周から保持する力が大きくなり、またこの高接着性
エポキシ樹脂１３が一体化されることにより圧電素子３
の質量が大きくなる。That is, when the volume of the space is made larger than the volume of the piezoelectric element 3, the highly adhesive epoxy resin 1 filled therein is filled.
Since the amount of 3 can be increased, the piezoelectric element 3
The force for holding the piezoelectric element 3 from the outer circumference is increased, and the highly adhesive epoxy resin 13 is integrated to make the piezoelectric element 3
The mass of becomes large.
そしてこのように圧電素子３を大量の高接着性エポキシ
樹脂で保持すれば、ハンマ９による衝撃で圧電素子３が
割れにくくなり、その結果として上述のごとく耐久性能
がきわめて長くなるのである。If the piezoelectric element 3 is held by a large amount of highly adhesive epoxy resin as described above, the piezoelectric element 3 is less likely to be broken by the impact of the hammer 9, and as a result, the durability performance becomes extremely long as described above.
また大量の高接着性エポキシ樹脂１３が一体化される結

撃で圧電素子３の振動回数が多くなり、それにともなっ

の安定したものとなるのである。When the mass of the piezoelectric element 3 becomes large as a result of the integration of a large amount of highly adhesive epoxy resin 13, the number of vibrations of the piezoelectric element 3 due to the impact of the hammer 9 increases, and the number of vibration waveforms also increases accordingly. , And the ignition characteristics are stable.
そして第７図(A)〜(D)に示す結果から(b)の耐久性能が

The volume of the space portion is 2.5 or more when the volume of the piezoelectric element 3 is 1, and the piezoelectric element 3 is housed in this space portion. And the piezoelectric element 3 and the highly adhesive epoxy resin 13 are integrated into a high voltage generator.

The discharge time is long, the discharge energy is large, the ignition characteristics are stable, and the piezoelectric element can be prevented from cracking or the like due to the impact of the impact mechanism, and a high voltage generator having excellent durability can be provided.

Not only a large coil is required, but also a coil storage portion must be provided, and the overall shape tends to be large, and even if this is done, the life of the piezoelectric element cannot be extended. The number of parts can be reduced because the coil for resonance is not used, and the coil housing does not have to be provided separately. Therefore, even if the space of the piezoelectric element housing becomes a little large, it does not increase in size. Moreover, since the life of the piezoelectric element can be extended, it is extremely effective.
