Abstract:
An electrostatic atomizer comprising:(a) a body defining an interior space, an exterior surface, an orifice extending through said body from said interior space to said exterior surface and a fluid entry port communicating with said interior space remote from said orifice; (b) a charge injection structure having a downstream end disposed within said interior space in the vicinity of said orifice; and (c) a counter electrode disposed in the vicinity of said orifice and electrically isolated from said charge injection structure; (d) said body comprising a dielectric structure having a portion disposed directly between said counter electrode and said interior space and directly between said downstream end of said charge injection structure and said counter electrode, whereby said counter electrode is electrically insulated from said interior space, said atomizer being devoid of electrically conductive surfaces other than surfaces of said charge injection structure exposed to said interior space in the vicinity of said charge injection structure.
