CYCLONE-TYPE SEPARATOR OF VACUUM CLEANER (VERSIONS) Russian patent published in 2009 - IPC A47L9/16 

FIELD: engines and pumps.

SUBSTANCE: proposed cyclone-type separator is designed as component of a vacuum cleaner inhausting dust and other contaminants particles through a suction head. The separator contains a primary cyclone that has an air inlet and an air outlet arranged in its bottom and top parts accordingly, a primary contaminant receptacle chamber encapsuling the primary cyclone and designed to provide for collection of contaminant particles as may be discharged therefrom and multiple secondary cyclones positioned over the primary cyclone perpendicular to its central axis. In the centre of the multiple secondary cyclones there is an air outlet connector arranged flow-communicating with the secondary cyclones. Outside the primary contaminant receptacle chamber there is a secondary contaminant receptacle chamber arranged providing for collection of contaminant particles as may be discharged from the secondary cyclones. With the proposed design version the separator contains a primary cyclone that has an air inlet and an air outlet arranged in its bottom and top parts accordingly, a primary contaminant receptacle chamber encapsuling the primary cyclone and designed to provide for collection of contaminant particles as may be discharged therefrom and multiple secondary cyclones positioned over the primary cyclone with a upgrade tilt relative to the primary cyclone upper plane. Outside the primary contaminant receptacle chamber there is a secondary contaminant receptacle chamber arranged serving for collection of contaminant particles as may be discharged from the secondary cyclones. With another separator design version the secondary cyclone unit contains multiple secondary cyclones positioned over the primary cyclone unit perpendicular to the central axis thereof, an air outlet connector positioned in the centre of the multiple secondary cyclones and flow-communicating therewith and a casing encapsuling the secondary cyclones.

EFFECT: separator space-effectiveness combined with uniformity of suction effort distribution per secondary cyclone and improved dust capturing performance.
