ACOUSTIC ATOMIZER Russian patent published in 2018 - IPC B05B17/04 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to devices for spraying of liquids, solutions. Acoustic atomizer comprises a body made in the form of a supply fitting with a central hole and rigidly connected to it coaxially with a cylindrical sleeve, in which a conical chamber for supplying liquid to the nozzle is located. Acoustic atomizer also comprises an acoustic unit. Nozzle made in the form of an inverted barrel is connected to the cylindrical sleeve, in its lower part. In the bottom of the barrel there 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 resonant 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 resonant chamber, made in the form of annular recess in the cylindrical sleeve, separated from the acoustic cavity by the annular partition, in which resonant bushings are fixed.

EFFECT: increased spraying efficiency due to spray cone increasing.
