Abstract: A spray gun for electrostatic painting in which an external electrode sustaining a high voltage can be fixed/removed while sustaining insulation from a spray unit on the ground potential side by limiting current supply to paint appropriately when electrostatic painting is performed using conductive paint, e.g. water based paint, and safety and handling performance are enhanced while ensuring the painting efficiency as the spray gun for electrostatic painting. On the outside of the spray gun (1) having the spray unit (5) at the forward end thereof, the external electrode (7) having an electrode projecting from the forward end part thereof is provided removably at the part (13) of the gun body being connected with the electrode while being separated from the paint passage such that it can be replaced readily. The part being connected with a high voltage output end part through a high resistor for limiting current can be shortened while sustaining safety by providing a turn-up part so that a sufficient creeping discharge preventing distance is ensured up to the exposed part on the outer surface. Furthermore, the electrode body itself is simplified so that it can be replaced with one touch, and it is composed of a flexible resilient material in order to prevent damage.

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.

The attaching and detaching section is set so that a distance at which a juncture with a high-voltage output end through a current-limiting high resistance reaches an outside surface exposure section can be sufficiently taken. The above section can be made to maintain safety and can be made shorter by providing the same with a turning over section. Further, the electrode body itself is simplified and is made exchangeable with a single action of exchange and in addition, the electrode body is configured of a flexible and elastic material for the purpose of failure prevention.
