Description

Cyclonic vacuum duster

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 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, 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, by first end wall, the second opposed end wall, intermediate member between described first end wall and second end wall is formed cyclone separator, described intermediate member is cylindrical or the band portion truncated cone shape, in the described cyclone separator, be provided with the air suction inlet tangential near described first end wall with described cyclone separator, the air outlet slit of tubulose stretches in the described intermediate member and with vacuum source from described first end wall and is connected, the intermediate member sidewall at the close described second end wall place on the described intermediate member is provided with the dust separation exit passageway, perhaps described second end wall is provided with the dust separation exit passageway, described dust separation exit passageway makes through the direction of motion of this isolated dust haply and be angle less than 90 degree between the eddy axis that the cyclone separator of first end wall to the second end wall is set up, the outlet of described dust separation exit passageway is arranged in 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 invention will be further described below in conjunction with drawings and Examples:
