Abstract
An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

19. An electrostatic sprayer apparatus comprising:
-
a main body housing configured to receive a power source; a nozzle assembly disposed at a first end of the main body housing; a reservoir configured to have a fluid disposed therein, wherein the reservoir is releasably attachable to the main body housing and is configured for fluid communication with the nozzle assembly when attached to the main body housing, the reservoir comprising; a reservoir housing comprising at least one guide surface, the at least one guide surface configured to align the reservoir housing with the main body housing for attachment thereto; an internal cavity defined by the interior surface of the reservoir housing and configured to receive the fluid; and an opening in the reservoir housing, the opening configured to enable the receiving of the fluid into the internal cavity; one or more releasable attachment mechanisms, the one or more releasable attachment mechanisms comprising one or more pairs of complementary engageable features on the main body housing and the reservoir housing that are configured for lockingly attaching the reservoir to the main body housing; a pump disposed within the main body housing, the pump configured to be powered by the power source and to pump at least a portion of the fluid from the reservoir to the nozzle assembly for dispensing the electrostatically charged at least portion of the fluid through the nozzle assembly to an exterior of the electrostatic sprayer apparatus; an electrostatic module disposed within the main body housing; at least one electrode assembly in electrical communication with the electrostatic module via a conductive wire, the at least one electrode assembly configured for electrostatic charging of the at least portion of the fluid; and a cap assembly configured to mate with the reservoir to occlude the opening, the cap assembly further configured to, when the reservoir is attached to the main body housing, form a seal between the reservoir and the pump and enable the fluid communication between the reservoir and the nozzle assembly. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. An electrostatic sprayer apparatus comprising:
-
a main body housing configured to receive a power source; a nozzle assembly disposed at a first end of the main body housing; a reservoir configured to have a fluid disposed therein, wherein the reservoir is releasably attachable to the main body housing and is configured for fluid communication with the nozzle assembly when attached to the main body housing, the reservoir comprising; a reservoir housing comprising one or more guide projections on a surface of the reservoir housing, each of the one or more guide projections configured to interact with a complimentary surface of the main body housing for the alignment of the reservoir relative to the main body housing during attachment thereto; an internal cavity defined by the interior surface of the reservoir housing and configured to receive the fluid; and an opening disposed in a top surface of the reservoir housing, the opening configured to enable the receiving of the fluid into the internal cavity, the opening defined by a neck having one or more flanges or threads; one or more releasable attachment mechanisms, the one or more releasable attachment mechanisms comprising one or more pairs of complementary engageable features on the main body housing and the reservoir housing that are configured for lockingly attaching the reservoir to the main body housing; a pump disposed within the main body housing, the pump configured to be powered by the power source and to pump at least a portion of the fluid from the reservoir to the nozzle assembly for dispensing the at least portion of the fluid through the nozzle assembly to an exterior of the electrostatic sprayer apparatus; a one-way valve in fluid communication with the reservoir, the one-way valve configured to vent atmospheric fluid into the internal cavity as the pump generates a vacuum in the reservoir; an electrostatic module disposed within the main body housing; at least one electrode assembly in electrical communication with the electrostatic module via a conductive wire, the at least one electrode assembly configured for electrostatic charging of the at least portion of the fluid; and a cap assembly configured to mate with the neck of the opening to occlude the opening of the reservoir, the cap assembly comprising; a cap body comprising one or more complimentary features configured to engage with the one or more flanges or threads of the neck for the mating thereto; and a conduit disposed on a top surface of the cap body, the conduit configured for fluid communication with the pump; wherein the cap assembly is further configured to, when the reservoir is attached to the main body housing, form a seal between the reservoir and the pump and enable the fluid communication between the reservoir and the nozzle assembly; and wherein the reservoir and the cap assembly are configured such that, when the reservoir is attached to the main body housing, the cap assembly mated with the opening is disposed inside of the main body housing. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48)
