Abstract:
1. An electrostatic sprayer, comprising: a nozzle disposed at an end of the electrostatic sprayer, the nozzle including a liquid tip having an outlet for ejection of a liquid; 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 removable cap defining an aperture for permitting passage of an electrostatically-charged liquid spray therethrough, wherein the electrode is captively secured in the removable cap, and wherein the removable cap is detachably secured to the electrostatic sprayer for providing access to the nozzle and electrode when the cap is removed from the electrostatic sprayer; and a calibratable stop mechanism for controlling a position of the electrode with respect to the outlet of the liquid tip by controlling a position of the removable cap with respect to a fixed position of the liquid tip, whereby the position of the electrode with respect to the outlet of the liquid tip is settable and re-settable as the removable cap is removed and replaced once the stop mechanism is calibrated, wherein the calibratable stop mechanism includes a locking ring disposed around the distal end of the electrostatic sprayer at a position behind the removable cap in a direction away from the outlet of the liquid tip.
