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

FIELD: devices for spraying or atomizing liquids.

SUBSTANCE: invention relates to devices for liquids, solutions spraying. Acoustic unit for 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. 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 is located coaxially with a conical chamber and is made in the form of a coaxially located hollow resonant conical sleeve consisting of sections with resonant holes connected to the cavity for supplying compressed air or gas. Cavity for supplying compressed air or gas is located between the inner surface of the cylindrical sleeve and the hollow resonant conical sleeve which is connected by means of inclined cylindrical holes to the mixing chamber of the nozzle. Cavity with the supply of compressed air through resonant holes is connected to an additional resonant chamber, which is in the form of an annular recess in a cylindrical sleeve, separated from the cavity by an annular partition in which resonance sleeves are fixed.

EFFECT: increasing spraying efficiency due to spray cone increasing.
