Electrostatic spraying device and method for controlling electrostatic spraying device

摘要

An electrostatic spraying device (100) provided with a guard electrode (4) different from a spray electrode (1) and a reference electrode (2) between an opening (11) and an opening (12), the magnitude of voltage between the spray electrode (1) or reference electrode (2) and a third electrode being controlled within a predetermined range that is less than the magnitude of the voltage between the spray electrode (1) and the reference electrode (2).
