Abstract:
1. A device for spraying, a liquid that can be electrically insulating at least through electrostatic forces, the device being designed to atomize this liquid or to control the beat of the oscillations thereof, this device comprising a nozzle which forms a channel for feeding the liquid to at least one orifice for spraying said liquid out of the device and which incorporates, in proximity to this orifice, a first electrode and a second electrode configured to inject electric charges into the liquid, wherein the edge of this orifice comprises, on one side of the channel, at least one protruding end of the first electrode which protrudes into this channel and which is configured to be in contact with the liquid and, on another side of the channel, an electrically insulating nozzle body in which the second electrode is embedded adjacent to the first electrode, so that the intensity of the electrostatic field at said or each protruding end is maximized.
