DEVICE TO CLEAN VACUUM CLEANER FILTER Russian patent published in 2011 - IPC A47L9/20 

FIELD: personal use articles.

SUBSTANCE: subject matter of this invention is a device of debris separation for a vacuum cleaner comprising a filtration system, at the same time the specified device comprises a fold filter (13), and also a device (14) to clean the specified filter (13), comprising at least one element (23) of mechanical action resting against a wall of the filter (13), at the same time one of these parts formed by the filter (13) or elements (23) of mechanical action, is movable relative to the other part. The separation device is a device of secondary separation installed at the output of the primary filtration system, besides, the relative mechanical movement between the elements (23) of mechanical action and the filter (13) is ensured with a motor-reducer (10). The elements (146, 148, 444, 446) of mechanical action are installed inside the fold filter (130, 430) and are arranged in the form of several fingers in contact with the filter wall (130, 430), at the same time the specified fingers are installed at two levels along the filter length (130, 430), which reduces air flow turbulence inside the filtering system.

EFFECT: increased efficiency of cleaning.
