Electrostatic fluid sprayer with active fluid cloud dispersal feature and method of electrostatic spraying

An electrostatic sprayer system, comprising:

• a sprayer head for dispensing a charged active liquid containing an active spray compound, wherein the sprayer head includes a first liquid outlet for emitting the active liquid and aft first electrode adjacent to the first liquid outlet for charging the active liquid;
• an air compressor for supplying pressurized air to the sprayer head to form an air sheath between the first liquid outlet and the first electrode to eject the charged active liquid from the first liquid outlet;
• a first vessel containing the active liquid prior to dispensing;
• a second liquid outlet;
• a second electrode adjacent to the second liquid outlet;
• a second vessel containing the non-active liquid;
• a power supply for providing a current and a voltage of a single polarity to the first electrode;
• a flow controller for controlling a flow of the active liquid to the first liquid outlet of the sprayer head;
• and
• a control system for controlling the flow controller such that the active liquid is delivered to the first liquid outlet while spraying of the active liquid is selected, wherein the control system signals the flow controller to de-select spraying of the active liquid, and wherein the electrostatic sprayer system is further configured to emit charged droplets of the non-active liquid that is charged with the single polarity in conjunction with the flow controller de-selecting spraying of the active liquid, wherein the flow controller selects between delivering the active liquid from the first vessel to the first liquid outlet and delivering the non-active liquid from the second fluid vessel to the second liquid outlet, wherein the power supply supplies another voltage and another current to the second electrode to charge the charged droplets of non-active liquid, and wherein the aft compressor further supplies the pressurized aft to eject the charged droplets of non-active liquid.
