ACOUSTIC ATOMIZER Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for liquid spraying or atomizing.

SUBSTANCE: invention relates to equipment for spraying of fluids and can be used in fire fighting, agriculture, chemical industry and heat power engineering. This is achieved by the fact that in an acoustic nozzle for spraying liquids containing a hollow housing with a nozzle and a central core, the housing is provided with a channel for liquid supplying and contains a coaxial, rigidly coupled with housing bushing with a nozzle fixed in its lower part and made in the form of a cylindrical two-stage, the upper cylindrical stage of which is connected by means of a threaded connection to a central core coaxial with it having a central hole and mounted with an annular gap with respect to the inner surface of the cylindrical bushing, wherein the annular gap is connected to at least three radial channels formed in a two-stage bushing connecting it to an annular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical step, wherein annular cavity is connected to the body fluid supply channel, to a central core, in its lower part, a diffuser is rigidly attached, made in the form of a truncated cone coaxial with the central hole of the core and attached by its upper base to the base of the cylinder of the central core, and to truncated cone lower base by means of at least three spokes divider is attached, which is made in form of round end plate, which edges are bent towards the annular gap, and on the truncated cone outer side surface there are screw grooves.

EFFECT: high efficiency of liquid atomizing.
