【考案の詳細な説明】
本考案は１〜２ ＭＨｚの圧電振動子の厚み振動により

提供するものである。[Detailed description of the invention] The present invention relates to an improvement of an ultrasonic atomizer that atomizes liquids such as water and kerosene using the thickness vibration of a piezoelectric vibrator of 1 to 2 MHz. The purpose of the present invention is to provide a piezoelectric vibrator mounting structure that does not leak liquid even when used for a long period of time when atomizing.

た液体６を霧化するように構成している。A conventional ultrasonic atomizer has a hole 2 formed at the bottom of an atomization chamber 1, as shown in FIG. The liquid 6 stored in the atomization chamber 1 to a predetermined level is atomized by applying high-frequency human power to the piezoelectric vibrator 3 from an external oscillation circuit or the like.

There was a drawback that the liquid 6 leaked out of the atomization chamber 1 due to the loss of elasticity.
