Electrostatic Fluid Delivery System

An electrostatic sprayer device, comprising:

• a housing having a removable fluid reservoir, the fluid reservoir defining a cavity adapted to contain a fluid;
• at least one nozzle on the housing, the nozzle being fluidly connected to the reservoir via at least one fluid passageway, wherein the at least one nozzle emits fluid out of the housing in a direction;
• a pump in the housing coupled to the fluid reservoir, wherein the pump propels fluid from the reservoir to the at least one nozzle via the at least one fluid passageway, wherein the pump includes a diaphragm that moves relative to two channels inside the pump so as to propel fluid through the pump;
• an electrode assembly system that electrostatically charges the fluid as the fluid passes through the at least one fluid passageway, wherein the electrode assembly system includes:
• a first electrode inside the pump, wherein the first electrode applies an electrical charge to fluid entering the pump, and a second electrode inside the pump wherein the second electrode applies an electrical charge to fluid exiting the pump;
• an electrically conductive tube that defines a portion of the at least one fluid passageway, wherein at least an electrically conductive portion of the tube is electrically coupled to the electrostatic module, and wherein the electrically conductive portion of the tube physically contacts the fluid as the fluid flows through the tube such that the electrically conductive portion applies an electrical charge to the fluid;
• and wherein the electrostatic module also electrostatically charges the fluid inside the reservoir such that the fluid is electrostatically charged at both the reservoir and at the electrode assembly;
• a direct current battery inside the housing, wherein the battery powers at least one of the electrostatic module and the pump.
