Abstract: PROBLEM TO BE SOLVED: To provided an electrostatic coating spray gun excellent in operability and employing low voltage system for improving safety and for more miniaturization, the spray gun having been demanded since there are many problems in which an electrically conductive coating material causes a problem when electrified directly, consequently an external electrode system of indirect electrification is generally used however such system brings about a practical problem in handleability and safety when miniaturized.
SOLUTION: The electrostatic coating spray gun is constituted in such a way that an atomizer is arranged at the distal end of the spray gun to atomize the coating material discharged from a coating material nozzle arranged in the central part of the atomizer and the atomized coating material is applied to the objected to be coated while applying high-voltage static electricity to particles of the atomized coating material, wherein the potential of coating material side of the spray gun is set to be ground potential, a charging electrode as an external electrode is arranged on the outside surface or inside surface of an air cap and a compressed air flow passage is formed between a coating material jetting spout of the ground potential and the charging electrode. A discharge from the electrode to the coating material side (grounded side) is restrained in charging by compressed air, so that required potential is maintained, ionized discharging is efficiently performed and particles of the coating material are electrified. As a result, since a potential drop is prevented, the voltage necessary for electrifying particles of the coating material can be lowered.
