VACUUM CLEANER Russian patent published in 2019 - IPC A47L5/28 

FIELD: satisfaction of vital human requirements.

SUBSTANCE: disclosed is a vacuum cleaner comprising a nozzle (N) for cleaning a surface, a suction tube (T) for receiving inlet air from a nozzle (N), a cyclone device having a cyclone (C) and a container (DC) for contaminants, both directed perpendicularly to a suction tube (T). Inlet of cyclone device is connected with suction tube (T), from which inlet air moves, following in spiral around center, in first direction perpendicular to suction tube (T) to reach stage (V), on which the contaminants are separated from the inlet air to produce the cyclone outlet air. At this stage, the cyclone outlet air moves through the channel in a second direction perpendicular to the suction tube (T) and opposite to the first direction to reach the output of the cyclone unit. Vacuum cleaner comprises filter (F) for outlet air of cyclone and generator (A) of air flow for generation of air flow through suction tube (T), cyclone (C) and filter (F). When nozzle (N) touches surface and suction tube (T) is located in horizontal position, first and second directions are perpendicular to surface, wherein perpendicular concept allows deviation of not more than 35°.

EFFECT: vacuum cleaner is proposed.
