DISPOSABLE CARTRIDGE FOR ELECTROSTATIC SPRAY DEVICE

摘要

An electrostatic spraying device (5) being configured and disposed to electrostatically charge and dispense a product from a supply or cartridge (200) to a point of dispersal. This device has a reservoir (220) configured to contain the supply of product and a nozzle (280) to disperse the product. A channel is disposed between the reservoir (220) and the nozzle (280), wherein the channel permits the electrostatic charging of the product upon the product moving within the channel. A positive displacement mechanism is used to move the product from the reservoir (220) to the nozzle (280). A portion of the high voltage electrode being disposed between the reservoir and the nozzle is used to electrostatically charge the product within the channel at a charging location. A mixing mechanism may be disposed between the reservoir and the nozzle to reconstitute any product which may have separated. The high voltage contact may be spring biased in direction towards the high voltage electrode. The high voltage electrode may be annular to improve contact with the high voltage contact. A locking mechanism may be added to secure the connection between the high voltage contact and the high voltage electrode. A locking feature may be added to secure the disposable cartridge within the device. An ejection feature may be added to release the disposable cartridge from the device.
