Electrostatic attraction fluid jet device

摘要

An electrostatic attraction fluid jet device comprising an applied voltage control means (10) which is adapted to control a voltage applied to the fluid (2) in the nozzle (4), wherein a diameter of the fluid-ejecting hole (4b) of the nozzle (4) is equal to or less than 8 ¼m. The applied voltage control means (10) is adapted to control a voltage applied to the fluid (2) so that the amount of electric charge, induced to the droplet (3) of the fluid (2) which droplet (3) has just been ejected from the fluid-ejecting hole (4b), is equal to or less than 90 % of the amount of electric charge corresponding to Rayleigh limit of the droplet (3).
