Air-flow initially forms rotation status to the outer shroud of spiral wind impeller.The wherein outer shroud circumference of spiral wind impeller
On be provided with outer toroid, by the effect of inside and outside annulus with realize air-flow guide, improve spiral wind impeller
Structural strength and stability.Wherein, the overall incoming air area of spiral wind impeller is less than fuselage air-out area,
Make to have higher rotary speed in the case of same air quantity to resist the suction of negative pressure.
Furthermore it is possible to arrange dust-break cylinder inside two grades of cyclone cylinders 11, between dust-break cylinder and two grades of cyclone cylinders
Being provided with space, this space separates air channel for forming two grades of dust and gas, and dust laden air separates in these two grades of dust and gas
Realize helical rotation in air channel and to produce centrifugal force, dust is fallen along the inwall of two grades of cyclone cylinders.Dust-break
Cylinder medial wall in order to retrain dust and gas this dust-break cylinder inward turning change the line of production raw centrifugal force with resist negative pressure suction,
Realize efficiently separating of dust and gas.Wherein two grades of cyclone cylinders all can be integrated with spiral dust and gas segregation apparatus and add
Work molding structure, is directly mounted at the centre bit of two grades of cyclone cylinders by spiral dust and gas segregation apparatus after molding
The place of putting can complete assembling, and concrete molding mode does not limits.
Also include defecator 15 in the upper end of the air outlet of two grades of tornado dust and gas isolating constructions, filter dress
Putting 15 can be filter cotton, and micro-concentration dust and gas carries out final by filter cotton after fuselage air outlet again
Filter.
When needs vacuum cleaner works, ash storage box 2 is stretched in one-level dirt cup 1, and each assembly all assembles
Putting in place, now, L-type pivoted arm 4 goes to the bottom of ash storage box 2 at the deduction backspin pressing protruding 6, now
Cover plate 3 is built, and is formed with ash storage box 2 and seals, and ash storage box 2 is kept apart with one-level dirt cup 1, vacuum cleaner
Start working, when vacuum cleaner work is complete, when needing the dust within cleaning, extract ash storage box 2, effect
Being released by pressure on L-type pivoted arm 4, and be rotated down under gravity, cover plate 3 simultaneously
Being opened, now the dust in ash storage box 2 drops automatically in one-level dirt cup 1, thus user can be carried out
Disposable ash discarding operation.
The dirt cup structure of the vacuum cleaner with multi-stage cyclone in the present invention, including one-level dirt cup 1 and storage
Ash bin 2, is provided with cover plate 3 bottom ash storage box 2, cover plate 3 is arranged on the end of a L-type pivoted arm 4,
The other end of L-type pivoted arm 4 is fixed in rotary shaft 5, and whole L pivoted arm 4 can be around described rotary shaft 5
Rotate, in one-level dirt cup 1, be provided with a pressing protruding 6, when ash storage box 2 stretches into one-level dirt cup 1, press
Belling plays 6 and deducts L-type pivoted arm 4, makes cover plate 3 automatically cover ash storage box 2 along with L-type pivoted arm 4
