MULTICYCLONIC DEDUSTER (VERSIONS) Russian patent published in 2008 - IPC A47L9/16 

FIELD: items of personal and house use.

SUBSTANCE: multicyclonic deduster is used in a vacuum cleaner for clearing air involved by the soaking up brush and contains the dust removal case having suction tube executed on its bottom part and acting on the set length inhausting the air through it, and intended for gathering polluting particles separated from the sucked in air. The first cyclone is located in the case having the first inlet aperture executed in the bottom part of a cyclone with maintenance of the flowing connection with a suction tube, and intended for a direction of air sucked in through the first inlet aperture, and the subsequent branch of polluting particles by centrifugal separation. A number of the second cyclones is mounted inside the case, located outside of the first cyclone on set distances from each other and surrounding the first cyclone. The second cyclones serve for separation of small polluting particles from air let out from the first cyclone. Each of the second cyclones contains the external wall of the second chamber forming the chamber of the second cyclone for separation of small polluting particles from air let out of the first cyclone, and the second inlet apertures for maintenance of a stream of air which has been let out from the first cyclone, in chambers of the second cyclones. Above the case there the cover unit for directing the air let out from the first cyclone to the second cyclones, repeated filtration of air separated from polluting particles in the second cyclones, and release of cleared air outside. The cover unit contains an inlet/outlet cover with channels directing air outlet in corresponding second inlet apertures of the second cyclones of air with an aperture for release of air of the first cyclone, and directing channels for air outlet from the second cyclones partially entering into chambers of the second cyclones. The inlet/outlet cover is closed with the cover of a cyclone collecting air let out of the outlet directing channels, and letting it out. The cyclone cover contains the cylindrical case of the set height with, at least, one inlet aperture for inletting air let out through directing channels located in an inlet/outlet cover and an outlet aperture for letting the air outside. The cover is connected with an open top part of the cover case of a cyclone, and made detachable. The inlet aperture of a cover is executed in the centre of the case basis of a cyclone cover, white the outlet aperture of a cover is executed in a lateral wall of the case of a cyclone cover. The filtering element for filtration of air let out through a cover of a cyclone is located in air access between an inlet/outlet cover and a cyclone cover. The filtering element is inserted into the case of a cyclone cover and placed in air access between inlet and outlet apertures of the cover.

EFFECT: optimum efficiency of the dust collector and simplified clearing of a deduster.
