The basic Colpitts excavation circuit described above cannot be applied to an atomizer that uses a piezoelectric element that exhibits all capacitive characteristics near the resonance point of actual atomization. As driving means for such an atomizer, there are two methods: (1) applying a predetermined drive frequency to the piezoelectric element using an external oscillator circuit and changing the frequency according to the temperature characteristics, and (2) utilizing the capacitance of the atomizer. However, conventionally proposed means include arranging an inductance that resonates in series with this capacitance, extracting the resonance signal, and feeding it back to the amplifier to form a self-oscillation system.
