Abstract: An atomizer including an air motor and a rotary atomizing head is mounted in a front side of a housing member, outer surfaces of which are covered in a cover member. Further, a high voltage discharge electrode assembly is provided around a front side of the housing member, with an outer periphery of the cover member circumvented by a blade ring of the high voltage discharge electrode assembly. An edge portion in the shape of a thin blade is provided at a projected rear end of the blade ring. Thus, an electric field is concentrated at the edge portion to induce a corona discharge on and around the entire blade ring.

Abstract: An atomizer (1) which is composed of an air motor (2) and a rotary atomizing head (3) is mounted in a front side of a housing member (9), outer surfaces (9A) of which are covered in a cover member (10). Further, a high voltage discharge electrode assembly (15) is provided around a front side of the housing member (9), with outer periphery of the cover member (10) circumvented by a blade ring (17) of the high voltage discharge electrode assembly (15). An edge portion (19) in the shape of a thin blade is provided at a projected rear end of the blade ring (17). Thus, electric field is concentrated at the edge portion (19) to induce a corona discharge on and around entire blade ring (17).
