Dust filter system for a vacuum cleaner and vacuum cleaner

摘要

The unit (1) has an air inlet opening (3), and an air outlet opening (4), where air flows from the inlet opening to the outlet opening. A cylindrically formed grating structure (5) carries an air conducting unit (13) i.e. rod, that extends over a section of the structure. The structure has openings (7), and a dust filter (9) covers one of the openings. The conducting unit and the dust filter are separated from each other by a wall (14), where the dust filter and the wall are arranged at a distance from each other. The conducting unit is arranged at a casing surface of the structure.
