ACOUSTIC NOZZLE WITH VORTEX SPRAYER Russian patent published in 2018 - IPC B05B17/04 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to devices for spraying of liquids, solutions. Acoustic nozzle with the vortex atomizer contains housing made in the form of supply fitting with central hole and cylindrical sleeve rigidly and coaxially connected thereto, in which a conical chamber for liquid supply to the nozzle is located, as well as an acoustic unit. Nozzle made in the form of an inverted glass is connected to the cylindrical sleeve, in its lower part. In the bottom of the cup is a turbulent swirler of the air flow with at least two inclinations to the axis of the nozzle in the form of cylindrical holes and a central cylindrical throttle opening connected to the mixing chamber of the nozzle, in series connected to the diffuser outlet chamber. Acoustic unit consists of two resonant structures. One of the resonance structures is located in the cylindrical sleeve upper part and is made in the form of at least two Helmholtz resonators consisting of resonator spherical chambers with neck. Second resonant structure adjoins the nozzle with the bottom and cylindrical throttle opening end surface and is made in the form of additional resonance chamber, made in the form of annular recess in the cylindrical sleeve, separated from the acoustic cavity by the annular partition, in which resonance bushings are fixed.

EFFECT: technical result of invention is increasing spraying efficiency by spray cone increasing.
