Abstract
An electrostatic, liquid spray, rotary atomizer has an atomizer housing, a power supply within the housing and an atomizer cup at a front end of the housing. The atomizer cup, which is formed of a non-conductive material, has several elongate conductive pathways embedded in the body of the cup. Each conductive pathway has one end exiting an outer surface at a rear end of the cup for receiving the charge from the power supply and another end exiting an inner surface at a front end of the cup for conveying an electrical charge from the power supply to the liquid (paint) particles passing through the atomizer cup. A number of conductive extensions are embedded in a frustroconical front portion of the cup. Each conductive extension has one end which is contiguous with the inner surface exiting end of selected ones of the conductive pathways, a first opposite end portion exiting an outer surface of the frustroconical front portion of the cup and a second opposite end portion exiting an inner surface of the frustroconical front portion of the cup. An annular charge ring is mounted to the front of the atomizer housing and is configured to accommodate the atomizer cup with conductive pathways and extensions and has an access hole for facilitating insertion of a tool for quickly demounting the atomizer cup for cleaning or replacement.
