ELECTROSTATIC ROTARY ATOMIZING SPRAY DEVICE PROVIDED WITH ATOMIZER CUP

摘要

PROBLEM TO BE SOLVED: To remarkably reduce a charge present in a passage for sending a coating material to a rotating atomizer cup by embedding plural conductive extension parts in the conical trapezoidal front part of the atomizer cup and providing a 1st end part and a 2nd opposite end part in the conductive extension parts. SOLUTION: Plural conductive passages 240, 242 are formed in the main body of an atomizer cup 200 and the conductive passages 240, 242 are constituted of 2 kinds. The 1st kind of the conductive passage 240 is formed slenderly and each slender conductive passage 240 is provided with a 1st end part 240a and a 2nd end part 240b. Further, each extension part 244 of the 2nd slender conductive passage 242 is provided with a 1st end part 244a adjacent to a 2nd end part 242b of the 2nd slender conductive passage 242 and a 1st opposite end part 44b and a 2nd opposite end part 244c branched in the opposite end part of each extension part 244 are provided.
