Abstract
Discharge device includes voltage application circuit that applies output voltage to load including discharge electrode holding liquid to generate discharge in discharge electrode. Voltage application circuit includes a function of varying a magnitude of output voltage, and a function of switching a discharge period that is a period for varying the magnitude of output voltage to any one of a plurality of periods having different lengths with a lapse of time.
Claims12
A discharge device comprising:
- a voltage application circuit programmed to:
- apply an output voltage to a load including a discharge electrode holding a liquid to cause the discharge electrode to generate electrical discharge,
- vary a magnitude of the output voltage to increase and then decrease in one discharge period, and
- switch a discharge period to any one of a plurality of periods different from each other based on a lapse of time, the discharge period being a period from a time at which the magnitude of the output voltage starts increasing to a time at which the magnitude starts increasing again.
An electrostatic atomization device comprising
- a voltage application circuit;
- a discharge electrode configured to hold a liquid;
- and
- a liquid supply unit configured to supply the liquid to the discharge electrode, wherein
- the voltage application circuit is programmed to:
- apply an output voltage to the discharge electrode thereby electrostatically atomizing the liquid,
- vary a magnitude of the output voltage, and
- switch a discharge period to any one of a plurality of periods different from each other based on a lapse of time, the discharge period being a period from a time at which the magnitude of the output voltage starts increasing to a time at which the magnitude starts increasing again.
