An electrostatic sprayer system for dispensing and dispersing a liquid containing a spray compound includes a spray cloud dispersal feature that reduces the time that a residual spray cloud containing droplets including the spray compound remains suspended after spraying. A method of dispersing the residual spray cloud is implemented by a control system that causes a flow control system to deliver a non-active gas or liquid in conjunction with stopping delivery of the liquid containing the spray agent and charged with the same polarity, so that a charged cloud of the non-active gas or liquid, which may be air, displaces the suspended active fluid particles. The non-active gas or liquid may be dispensed for a predetermined time interval as determined by the control system, or the operator may control the time interval during which that the non-active fluid is dispensed.

An electrostatic spray device, including: a housing, a tubular member, a nozzle and an airflow providing member. In a first direction from a second end portion to a first end portion of the housing, a second opening of the tubular member is located at a side of a first opening of the housing away from the second end portion. The nozzle is at least partially located in a second accommodating space defined by the tubular member. The nozzle is configured to spray mist towards the second opening through a spray opening, and the mist leaves the electrostatic spray device from the second opening in a charged state. The airflow providing member is configured to provide airflow towards the first opening and the second opening.

An electrostatic fluid delivery system that is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a spray that can be directed onto a surface, such as a surface to be cleaned. The system is powered by a DC (direct current) power system. The device can electrically or positively charge a liquid or gas.

A spray ionization device comprising: a first tube that has a first flow path through which a liquid can flow and a first outlet on one end thereof from which the liquid is sprayed; a second tube that surrounds the first tube with a gap therebetween, has a second flow path through which a gas can flow, and has a second outlet on the one end thereof; and an electrode that extends through the interior of the first flow path of the first tube, from the other end thereof to the one end, said electrode being arranged such that the tip thereof is at the same position as the first outlet or is further on the other end side than the first outlet, and said electrode being able to apply a voltage to the liquid by means of a power source connected to the electrode.

The present invention is directed to an electrostatic sprayer for applying disinfectants, agricultural production, pesticides, and other chemicals and liquid solutions. The electrostatic sprayer may be used for indoor and outdoor applications. The electrostatic sprayer provides a solution tank for holding a treatment solution, a base for holding and protecting the mechanical and electrical components, including a power supply, solution pump, and electrostatic generator, of the electrostatic sprayer, a supply hose, and a spray wand. The solution tank further includes input and exit filters to remove particles that may damage the solution pump of clog the spray wand. The spray wand includes spray nozzles with backflow valves and metering disks to control the flow of the treatment solution and close the valve when the treatment solution is not sufficiently pressurized to pass through the backflow valve to prevent leak when not in use. An electrostatic switch is also provided for selectively powering on the electrostatic generator. The electrostatic generator provides a positive charge to an electrode in the solution tank and a negative charge to a grounding strip in the handle of the spray wand providing a negative pathway through Earth to the objects being treated enhancing the electrical attraction of the treatment solution to those items. A grounding strap is also provided to be worn by the user to reduce the resistance in the path between the grounding strip and Earth by bypassing some of the user's clothing and protective gear that may provide resistance to the path.
