Abstract
The present invention is an electrostatic spraying device to electrostatically charge and dispense a product from a reservoir to a point of dispersal that includes a nozzle having an exit orifice and being disposed at the point of dispersal to disperse the product. A channel is included that permits the electrostatic charging of product. A positive displacement mechanism is used to move the product from the reservoir to the nozzle. A power source supplies an electrical charge. A portion of a high voltage electrode being disposed between the reservoir and the nozzle is used to electrostatically charge product within the channel at a charging location. A distance between the charging location and the nozzle exit orifice is governed by V /d<100,000, wherein V =an output voltage of said high voltage power supply and d=linear distance between the charging location and said nozzle exit orifice.
