Electrostatic spraying device

摘要

An electrostatic spraying device includes a device body having a paint supply passage, a paint nozzle located on a distal end of the device body and having a paint flow passage communicating with the paint supply passage and a paint outlet, a high-voltage generating part configured to generate high voltage with which paint is charged, and a high-voltage electrode disposed a predetermined distance backwardly away from the paint outlet on an outer periphery of the device body, so as to be separated from the paint flow passage. The device further includes a conductor located between the high-voltage generating part and the high-voltage electrode, a spring located between the high-voltage electrode and the conductor, a high-voltage electrode case detachably attached to the device body to enclose the high-voltage electrode, and a grip mounted on an end of the device body, which end is located opposite the paint nozzle.

1. An electrostatic spraying device comprising:
a device body having a paint supply passage connected to a paint supply source; a paint nozzle provided on a distal end of device body and having a paint flow passage communicating with the paint supply passage and a paint outlet formed through a distal end of the paint flow passage; a high-voltage generating part configured to generate high voltage with which paint sprayed from the paint outlet is charged; a high-voltage electrode to which the high voltage generated by the high voltage generating part is applied, wherein the high-voltage electrode is disposed at a position a predetermined distance backwardly away from the paint outlet on an outer periphery of the device body, so as to be separated from the paint flow passage and thereby to be insulated from the paint flow passage; a conductor provided between the high-voltage generating part and the high-voltage electrode; a spring provided between the high-voltage electrode and the conductor; a high-voltage electrode case detachably attached to the device body to enclose the high-voltage electrode; and a grip provided on an end of the device body, which end is located opposite the paint nozzle.
