DEVICE FOR DUST SEPARATION IN VACUUM CLEANER Russian patent published in 2011 - IPC A47L9/16 

FIELD: personal use articles.

SUBSTANCE: device for dust separation is intended for a vacuum cleaner. Device comprises dust separator, forming multiple feeds for air, guide for suction, which directs air flow, containing dust, to dust separator, distribution unit, connected to multiple feeds for air, for distribution of air from guide for section into multiple feeds for air of dust separator, dust exhaust, arranged with the possibility to discharge dust separated from air sucked through according feeds for air, and container for accumulation of dust discharged from dust exhaust. Air feeds are arranged at each side of dust separator, and dust exhaust is arranged between air feeds. Dust separator comprises body to develop cyclone air flow and a pair of lateral sides formed to shape each side of casing. Each of lateral sides of casing forms an exhaust for air discharge, from which the dust is separated. Device may comprises multiple exhausts formed in separator, arranged with the possibility to exhaust air, from which dust is separated. In version of device design each of cyclone air flows in separator moves in direction of meeting each other.

EFFECT: improved efficiency of dust separation with reduced losses of air, reduced efforts of user when manipulating container for dust discharge.
