Abstract
An electrostatically atomizing device includes an emitter electrode, an opposed electrode disposed in an opposed relation to the emitter electrode, liquid supply means for supplying a liquid to the emitter electrode, and high voltage generating means for applying a high voltage across the emitter electrode and the opposed electrode. The liquid supplied onto the emitter electrode is electrostatically charged through application of the high voltage, as a result of which charged minute liquid particles are discharged from a discharge end of the emitter electrode. The device includes detecting means for detecting a discharge condition developed between the emitter electrode and the opposed electrode, and a controller for controlling the high voltage generating means to regulate its voltage output so as to maintain a predetermined discharge condition, based on detection results by the detecting means. Charged minute particles can be continuously generated in an amount corresponding to the predetermined discharge condition, by adjusting the discharge voltage that is applied to the emitter electrode.
