RUBBISH SEPARATING DEVICE TO VACUUM CLEANER Russian patent published in 2007 - IPC A47L9/16 

FIELD: deices for separating and collecting rubbish driven to motion with the aid of airflow created by means of suction aggregate of vacuum cleaner.

SUBSTANCE: device includes air inlet duct opened in tangential direction to rubbish separating chamber restricting inner volume in the form of cylinder. In central part of chamber there is at least one opening communicated with duct connected with suction aggregate of vacuum cleaner. Rubbish separating chamber has duct for disposal of rubbish arranged in radial direction and communicated with sealed reservoir for collecting centrifugally separated rubbish. Air inlet duct and duct for separating rubbish are formed in the same level n rubbish separating chamber. Diametrical cross section of said chamber exceeds by 2 -10 times the least cross section of ducts for supplying rubbish from suction tip of vacuum cleaner. End portion of rubbish disposal duct communicated with rubbish separating chamber has height equal to height of said chamber; cross section of inlet duct is round one and it has diameter 25 - 35 mm.

EFFECT: reduced size, simplified design of device.
