Abstract

The cyclone type dust cup of vacuum cleaner includes a casing with air outlet and tangent air inlet, and a separator set inside the casing. The separator has an air inlet, an isolating cover below the air inlet, and a double-layer pipe with coaxial inner pipe and outer pipe in greater height than the inner pipe and closed bottom, and the air inlet is communicated through the inner pipe to the air outlet. The present invention features that the cup-shaped air inlet of the separator consists of several screw sheets arranged homogeneously; the air outlet of the dust cup may be set in the cup cover or the bottom of the casing; one three-blade rotating sheet is set inside the extending pipe below the outer pipe; and the dusty air is thrice separated inside the cavity of the dust cup in high separating effect.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaner manufacturing, in particular to a separation device for air and dust of a centrifugal vacuum cleaner. Background technique [0002] The application number I have applied for is "200510049880.2", "Integral double-separated vacuum cleaner dust cup". Compared with the prior art, although the effect of separating air and dust has been greatly improved, there is still a small amount of fine dust that has not been separated. The air flow is adsorbed on the filter of the vacuum cleaner. After repeated use, a lot of dust still accumulates on the filter, which blocks the circulation of the air over time. Therefore, it is necessary to produce a separator with better separation effect on the original basis. . Contents of the invention [0003] The technical problem to be solved by the present invention is that the separation effect of the dust cup of the vacuum cleaner with two separation functions...
