DEDUSTING DEVICE FOR VACUUM CLEANER Russian patent published in 2009 - IPC A47L9/16 

FIELD: items of private and domestic use.

SUBSTANCE: dedusting device is provided for separation of dust from air in vacuum cleaner. Device allows cyclone units, containing the first cyclone unit, the second cyclone unit, connected with providing of air receiving from the first cyclone unit and located inside the first cyclone unit, and the third cyclone unit, connected with providing of air receiving from the second cyclone unit and located inside the second cyclone unit. Cyclone units are connected for successive passing of air from one cyclone unit to the other cyclone unit and each of them is implemented with providing of creation of vortex motion of air and dust separation from air. Air is introduced into the top part of the first cyclone unit and withdrawn through its bottom part, introduced into bottom part of the second cyclone unit and withdrawn through its top part, and introduced into the top part of the third cyclone unit and withdrawn through its bottom part. Each cyclone unit contains dust-collecting chamber and case of dust-collector, in which casing of the second dust-collector is located inside case of the first dust-collector, case of the third dust-collector is located inside case of the second dust-collector. The first dust-collecting chamber is limited by casing of the first dust-collector and case of the second dust-collector, the second dust-collecting chamber is located inside case of the second dust-collector, and the third dust-collecting chamber is limited by case of the third dust-collector and exhaust pipe.

EFFECT: compactness of deduster at high performance of dust separation in it without reduction of sucking effort.
