Abstract (en)

[origin: EP2774687A1] An electrostatic sprayer (1) includes: a tank (71); a spray nozzle (72) attached to the tank (71); a transport unit (40) which transports a spray liquid in the tank (71) to a tip (72a) of the nozzle (72); a counter electrode (12) exposed at an outer surface; and an electric field generation mechanism (6) which applies a voltage to the spray liquid to generate an electric field between the tip (72a) of the spray nozzle (72) and the counter electrode (12) so that the spray liquid is sprayed from the spray nozzle (72). The electrostatic sprayer (1) is provided with an output control section (62) which switches the polarity of the voltage applied by the electric field generation mechanism (6) alternately between the positive and negative polarities, and the counter electrode (12) is comprised of an ungrounded electrode.
