  • Patent number: 9498785
    Abstract: 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.

  • Publication number: 20150021419
    Abstract: An electrostatic spraying device includes a device body having a paint supply passage connected to a paint supply source, a paint nozzle located 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 which generates high voltage with which paint sprayed from the paint outlet is charged, and a high-voltage electrode to which the high voltage generated by the high voltage generating part is applied. 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 thereby to be insulated from the paint flow passage.
