ELECTROSTATIC SPRAY DEVICE

摘要

An electrostatic spray device (10) has a spray cartridge (15), an electric power source (16), and a controller (17). In the spray cartridge (15), a nozzle unit (30) is provided at the lower part of a solution tank (20). A spray nozzle (31) of the nozzle init (30) is positioned below the liquid level (51) in the solution tank (20). There is a head difference between the tip of the spray nozzle (31) and the liquid level (51) in the solution tank (20), and an aqueous solution in the solution tank (20) is supplied into the spray nozzle (31) by the head difference. When a voltage is applied to the spray head (31) by the power source (16), the aqueous solution is sprayed from the tip of the spray nozzle (31).
