CYCLONE-TYPE DUST COLLECTOR FOR VACUUM CLEANER Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: dust collector has cyclone casing mounted on extension sleeve of vacuum cleaner and adapted for creating swirling air flow from admitted air, grid for filtering of backward swirling air flow, cyclone cover equipped with partially supported plate arranged in accordance with grid, garbage passage for directing garbage particles into garbage receiver, first connecting member for connecting cyclone casing to garbage receiver and second connecting member adapted for connecting garbage receiver to cyclone cover. Thus, grid is prevented from contamination with garbage accumulated in garbage receiver and tending to be drawn back, regardless of user's position. Also, grid is prevented from damage or garbage sticking to grid is prevented from falling during removal of accumulated garbage by user.
