Electrostatic sprayer

An electrostatic sprayer, comprising:

• a spray gun comprising a nozzle, the spray gun being adapted to combine, at the nozzle, pressurized spray media and pressurized air into an atomized mixture;
• and
• a generator adapted to electrostatically charge, at the nozzle:
• (a) the pressurized spray media;
• or
• the pressurized air;
• or
• both the pressurized spray media and the pressurized air;
• and
• (b) the atomized mixture,
• wherein the nozzle comprises:
• a nozzle body defining opposing inlet and outlet end portions, a first internal passageway extending axially through the nozzle body between the inlet and the outlet end portions and along which the pressurized spray media is communicated, and a second internal passageway along which the pressurized air is communicated, an inlet portion of the second internal passageway extending radially inward, perpendicular to the axial extension of the first internal passageway, into the nozzle body from an exterior surface of the nozzle body,
• wherein the nozzle body further comprises external threads located on the exterior surface proximate the outlet end portion of the nozzle body;
• a spacer positioned at the outlet end portion of the nozzle body and defining a third internal passageway along which the atomized mixture is communicated;
• a static charge ring defining opposing inlet and outlet end portions and a fourth internal passageway extending axially through the static charge ring between the inlet and outlet end portions via which the atomized mixture is discharged from the spacer and to which static charge ring the generator communicates electrostatic charge(s) to electrostatically charge the atomized mixture,
• wherein the static charge ring further comprises internal threads located on an interior surface proximate the inlet end portion of the static charge ring and external threads located on an exterior surface proximate the inlet end portion of the static charge ring;
• and
• a nozzle defining a fifth internal passageway to which the atomized mixture is communicated from the fourth internal passageway of the static charge ring, and via which the atomized mixture is discharged from the nozzle,
• wherein the nozzle tip further comprises internal threads located on an interior surface of the nozzle tip;
• wherein the internal threads of the static charge ring threadably engage the external threads of the nozzle body such that the static charge ring is connected to the nozzle body;
• wherein the spacer is received within the fourth internal passageway of the static charge ring such that at least a portion of the spacer is positioned axially between the outlet end portion of the nozzle body and the outlet end portion of the static charge ring;
• and
• wherein the internal threads of the nozzle tip threadably engage the external threads of the static charge ring such that the nozzle tip is connected to the static charge ring.
