CYCLONE SEPARATOR FOR VACUUM CLEANER Russian patent published in 2009 - IPC A47L9/16 

FIELD: instrument making.

SUBSTANCE: cyclone separator for vacuum cleaner incorporates the 1^st cyclone to feed air into its lower part and to release air through its top part, designed to separate dust and air. The 1^st dust collector is arranged right around the 1^st cyclone, the former communicating with the latter. Several 2^nd cyclones are fitted above the 1^st cyclone to separate dust and air and communicating with the latter. The 1^st cyclone houses the 2^nd dust collector to communicate with several 2^nd cyclones. In compliance with one version, the cyclone separator includes the 1^st cyclone assembly comprising the 1^st cyclone incorporating an air intake element arranged at the 1^st cyclone bottom and an air release element fitted at the 1^st cyclone top. The 1^st dust collector envelopes the 1^st cyclone and has a chamber to collect dust coming from the latter. The 1^st cyclone houses the 2^nd dust collector to communicate with several 2^nd cyclones. The 2^nd cyclone assembly is arranged above the 1^st cyclone one and incorporating several 2^nd cyclones fitted above the fist cyclone assembly. The bottom of the 2^nd cyclones accommodates an element to guide dust and to communicate 2^nd cyclones with 2^nd dust collector. The 2^nd cyclone assembly is furnished with the top cover, while the 2^nd cyclones are closed with a casing. The 2^nd cyclone assembly is designed so that the lower end of 2^nd cyclones seats at a distance from the 1^st cyclone.

EFFECT: compact design, efficient dust separation and no effect of collected dust on air flow swirling.
