Abstract:
1. A nozzle for an electrostatic sprayer, the nozzle comprising: a nozzle body having an inlet for receiving a liquid; a removable liquid tip having an outlet at a distal end thereof for ejection of the liquid, wherein the base of the liquid tip is removably mounted to the nozzle body and contacts a surface of the nozzle body forming a seam; an electrode disposed around the outlet of the liquid tip for generating an electric field between the electrode and the liquid for charging the liquid; a dielectric shroud separate from the nozzle body and mounted on the nozzle body so that the dielectric shroud is disposed around the base of the liquid tip at the surface of the nozzle body to form a gap extending between the seam and an inner surface of the dielectric shroud, to prevent leakage currents from reducing an intensity of the electric field; and a removable cap secured to the nozzle body and covering the removable liquid tip and the dielectric shroud.
