CYCLONE-TYPE DUST COLLECTOR AND VACUUM CLEANER WITH CYCLONE-TYPE DUST COLLECTOR Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: cyclone-type dust collector has first cyclone for purifying of dust-laden air, plurality of second cyclones for separation of finely dispersed dust particles by secondary extraction of dust with the use of centrifugal force from air, which had been preliminarily purified in first cyclone, and inlet-outlet cover, which is mounted on top part of first cyclone and of second cyclones for providing communication between first cyclone and second cyclones and through which dust-free air is discharged from second cyclone.

EFFECT: increased dust collecting efficiency by using plurality of cyclones as parts of compact construction to thereby prevent suction force of vacuum cleaner from decreasing.
