Abstract:
A spraying device for dispensing electrostatically charged liquid droplets comprising:a container holding a liquid at one end and having an aperture at another end; a nozzle assembly including (a) a longitudinal hollow tube terminating in a metallic structure, (b) the metallic structure including at least one aperture formed therein for fluid communication with the hollow tube; and (c) a wire conductor having an end connected to the metallic structure; the longitudinal hollow tube inserted in the aperture of the container for fluid communication with the liquid; a charge accumulator disposed in the liquid for accumulating electrostatic charges; and the wire conductor having another end connected to the charge accumulator; wherein the wire conductor transfers the electrostatic charges to the metallic structure and the liquid, when dispensed as droplets by the nozzle, receives the electrostatic charges.
