DEVICE FOR DUST SEPARATION OF VACUUM CLEANER Russian patent published in 2011 - IPC A47L9/16 

FIELD: personal use articles.

SUBSTANCE: there are versions to implement device for dust separation of a vacuum cleaner. Device for separation of dust for vacuum cleaner in compliance with the present versions of implementation includes a cyclone, where multiple vortex air flows are formed; hole for dust exhaust in order to discharge dust separated with the help of multiple vortex air flows. Dust-collecting reservoir to hold dust discharged from dust exhaust hole, in which cyclone comprises vessel, where air passes along its inner surface, and a pair of sides. At the same time each of sides forms one of two side surfaces of body and forms an outlet hole for air exhaust.

EFFECT: increased efficiency of dust separation and is achieved by increasing quantity of holes, to let through air flows formed in cyclone; increased volume of air flow passing through cyclone, due to reduction of losses when passing through increased quantity of air channels.
