Automatic emitter point cleaners with a detection surface cleaner

Abstract

Example automatic emitter point cleaning systems include: an emitter point configured to produce at least one of positive ions or negative ions within or proximate to an ionization delivery path; an emitter frame configured to hold the emitter point in or proximate to the ionization delivery path; a brush; a motor coupled to the brush to actuate the brush to move past the emitter point; a detection surface coupled to the brush; a sensor configured to detect when the brush is in a predetermined position with respect to a reference position by detecting the detection surface; and a detection surface cleaner configured to clean the detection surface while the brush moves with respect to the emitter frame.
