<p>A spiral vacuum cleaner includes a shell (1), a filter chamber covered by the shell (1), a filter placed in the filter chamber, a motor chamber, a vane motor placed in the motor chamber, and a bottom plate (2) covering the internal structure. A suction inlet is disposed on said shell (1), and an air outlet is disposed on the bottom plate (2). Air is sucked into the cleaner through the suction inlet, and then exhausted from the air outlet on the bottom plate (2) after passing through the inside of the cleaner, where an air cushion is formed to achieve a spiral effect. One concave exhaust chamber (21) is respectively and symmetrically disposed at both sides of a central axis of said bottom plate (2). Exhaust holes (22) are provided on the latter half of said exhaust chamber (21) and uniformly distributed in a dot matrix manner. The spiral vacuum cleaner ensures better anti-vibration and anti-shaking performances, and is easier to be operated.</p> |
