Abstract
The cyclonic vacuum cleaner has a cyclonic separator comprising one first end wall, one opposite second end wall and one intermediate part. The intermediate part is cylindrical or partially truncated cone shaped; and the first end wall has one tangent air inlet. The separator features that the second end wall has such a dust separating outlet passage to make the separated dust in the angle of about 90 deg to the axis of vortex flow and the outlet of the separated dust passage is inside the dust collector. The cyclonic separator results in high efficiency separation of the dust particles to the dust collector under the action of the centrifugal force.
Description
The present invention relates to a kind of vacuum cleaner.
In the prior art, EP0966912 discloses a kind of cyclone separator that is used on the vacuum cleaner, it is by first end wall, second end wall of offside and intermediate member are formed the cyclone separator of cyclone, above-mentioned intermediate member is cylindrical or the band portion truncated cone shape, intermediate member has particle sucking-off chamber, eddy flow is gone out by rotational flow separation through the particle that intermediate member blows to second end wall, cyclone is provided with the tangential air suction inlet near the sidewall of first end wall, the tubulose air outlet slit from first end wall stretch into intermediate member and and vacuum source be connected, the separation portion of end wall chamber is stretched in above-mentioned particle sucking-off chamber, open at its sidewall the passway of dust separation exit passageway, and eddy current that cyclone set up general through this particle revolve a quadrature, particle is left in the dust arrester outside the separation portion.In fact, wanting the separated eddy flow track of particle in the cyclone inner chamber roughly is spirality, the movement locus of described particle when separated not can with eddy current axle quadrature, and above-mentioned dust separation exit passageway of the prior art and eddy current axle are quadrature (referring to its accompanying drawings 7), therefore the movement locus of dust separation exit passageway and particle does not match, and influences the motion of particle and is unfavorable for separating of particle and air.
The object of the present invention is to provide a kind of particle that makes to enter dust storage chamber along split tunnel, make the Cyclonic vacuum duster of dust separation better effects if.
Technical scheme of the present invention is: a kind of Cyclonic vacuum duster, form cyclone separator by first end wall, second opposed end wall, intermediate member between described first end wall and second end wall, described intermediate member is cylindrical or the band portion truncated cone shape, in the described cyclone separator, be provided with the air suction inlet roughly tangential with the inwall of described intermediate member near described first end wall; Be provided with the vacuum source suction inlet that is connected with vacuum source away from the described first end wall place; Have the passway of dust separation exit passageway on described second end wall, described dust separation exit passageway make through the direction of motion of this isolated dust haply and the angle α between the eddy axis R that the cyclone separator of first end wall to the second end wall is set up less than 90 degree, the outlet of described dust separation exit passageway is positioned at dust storage chamber, makes isolated dust stay in the described dust storage chamber.
The present invention compared with prior art has following advantage:
Because the set dust separation exit passageway and the movement locus of particle match substantially; therefore make and successfully under action of centrifugal force, to be separated in the dust storage chamber by isolated particle along the dust separation exit passageway; the dust separation exit passageway is positioned on second end wall, makes dust can guarantee separated going out.
