CYCLONE-TYPE DUST COLLECTOR AND HANDLE UNIT FOR VACUUM CLEANER PROVIDED WITH SUCH DUST COLLECTOR Russian patent published in 2006 - IPC A47L9/16 A47L9/32 

FIELD: mechanical engineering, in particular, vacuum cleaner having cyclone-type dust collector and handle unit placed in vacuum cleaner suction channel which connects vacuum cleaner casing with suction inlet unit.

SUBSTANCE: handle unit for vacuum cleaner has handle tube equipped with inlet connected to suction inlet and adapted for passage of air therethrough and outlet connected to vacuum cleaner casing and adapted for passage of air therethrough. Handle is provided on handle tube for gripping by user. Cyclone-type dust collector is projecting from handle tube and adapted for centrifugal separation of dust from outer air sucked through inlet of handle tube, and for discharge of cleaned air through outlet of handle tube. Free end of cyclone-type dust collector is directed downstream of handle tube, along suction channel which connects inlet suction unit to vacuum cleaner casing. Cyclone-type dust collector is mounted on suction channel which connects vacuum cleaner casing equipped with vacuum generator to suction inlet unit which sucks dust from surface to be cleaned, and is adapted for centrifugal separation of air sucked through suction inlet unit. Dust collector has cyclone case formed at handle unit which connects extension tube coupled to suction inlet unit with flexible hose joined to vacuum cleaner casing, and dust collecting reservoir detachably connected to cyclone case, wherein end of dust collecting reservoir is directed downstream from handle unit, along suction channel.

EFFECT: increased efficiency through the use of auxiliary suction device in conjunction with cyclone-type dust collector.
