PROBLEM TO BE SOLVED: To provide an atomizer capable of detecting a water leakage, which requires no electrode for water leakage detection and is not affected by sticking of bubbles and the temperature change.SOLUTION: A driving circuit 101 or a resistance value detection circuit 102 is connected between the exciting electrode E of a vibrator 32 and a vibration plate 31 via a switching circuit 103. Normally the switching circuit 103 selects the diving circuit 101 to apply the driving voltage of the driving circuit 101 to the vibrator 32 and in timing performing the water leakage detection, selects the resistance value detection circuit 102. In this state, the resistance value detection circuit 102 generates a voltage signal corresponding to the insulation resistance value between the exciting electrode E of the vibrator 32 and the vibration plate 31.COPYRIGHT: (C)2012,JPO&INPIT【課題】漏水検出用の電極が不要で、且つ気泡の付着や温度変化の影響を受けずに漏水を検知できる噴霧装置を構成する。【解決手段】振動子32の励振電極Eと振動板31との間に切替回路103を介して駆動回路101又は抵抗値検出回路102が接続される。通常、切替回路103は駆動回路101を選択して、駆動回路101の駆動電圧を振動子32へ印加し、漏水検知を行うタイミングでは、抵抗値検出回路102を選択する。この状態で抵抗値検出回路102は振動子32の励振電極Eと振動板31との間の絶縁抵抗値に応じた電圧信号を発生する。【選択図】図7
