STAREEVA SWIRL ATOMIZER Russian patent published in 2018 - IPC B05B1/34 B05B1/26 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to fluid and solvent sprayers and may be used in machine building, chemical and food industries. Swirl atomizer comprises case with screw aligned in the case bottom section, and located in case upper part union with cylindrical hole for fluid supply connected with diffuser, axially symmetric to case and union. Screw is pressed into the body to make cylindrical chamber above said screw and aligned with the diffuser and communicated therewith. Screw is made solid. Outer surface of the screw is two serially connected surfaces, one of which is at least a single-threaded groove with a right or left thread and is located inside the housing. Second smooth surface represents a body of revolution axisymmetrically connected with spraying disc located perpendicular to body axis to extend beyond casing bottom end. Both straight line and n-order curve may make a generating line of said surface. Surface of the spraying disc extending beyond the casing bottom end is made bent toward the lower part of the case and has radial cuts on the peripheral part alternating with the continuous part of the surface of the spraying disc. Diffuser is connected to the end lower part of the atomizer body, enclosing the spray disk. At the top of the diffuser there are at least three ejection openings. Spraying disc is displaced along the axis of the atomizer down from the smooth surface of the body of rotation of the screw connected to the screw surface of the screw by an amount depending on the viscosity of the liquid being sprayed and connected to the screw by means of a rod. In the diffuser, holes are formed on its lateral surface that are designed to suck external air into the dissector, consisting of a perforated plate in the form of a circle mounted on the diffuser cut. Two additional shell mesh splitters are installed on the plate. Cone with a vertex facing the diffuser is fixed on top of the perforated plate. Spherical perforated surface is fixed from below.

EFFECT: technical result of the invention is an increase in the spraying efficiency of liquid.
