Abstract

An electrostatic spray nozzle including: a paint nozzle having a labial paint spout hole for spurting a paint under pre­ determined liquid pressure; an air nozzle having an air blow hole forwardly of the paint spout hole for blowing air streams to­ ward the spurted paint to accelerate atomization of the paint; and a needle electrode located forward of the air spout hole and applied with a high voltage to charge the atomized particles of the paint to a predetermined potential. Atomization of the paint which is spurted from the paint spout hole is accelerated by pressurized air streams from the air spout hole, while prevent­ ing the tailing phenomenom. The atomized paint particles are charged by passage through an ionizing zone which is formed around the needle electrode, thereby promoting the efficiency of paint deposition and at the same time the efficiency of paint atomization by the electrostatic atomizing action.
