Abstract
An electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, and a cooling means which condenses the water on the emitter electrode from within the surrounding air, and a high voltage source applying a high voltage across the emitter electrode and the opposed electrode to electrostatically charge the water for atomizing charged minute water particles from a discharge end of the emitter electrode. The device further includes a controller for discharging the charged minute water particles in a stable manner. The controller monitors a discharge current flowing between the two electrodes to control the cooling means for keeping the discharge current at a predetermined level, thereby regulating the atomizing amount of the charged minute particles from the emitter electrode.
