Embodiment Construction

[0011] Such as figure 1 , figure 2 As shown, the cyclone-type secondary separation dust cup of the vacuum cleaner includes a dust cup housing 1, an air outlet 2 opened on the housing and an air inlet 3 tangential to the surrounding wall of the housing, a separator and a bracket placed in the housing 4. The air inlet 13 of the separator is arranged at the lower half of the annular cover 12 . Its position is lower than the air inlet 3 of the casing. There are more than two cylinders 6 arranged side by side with tangential air inlets 7 on the upper ends arranged in the annular cover, and seven cylinders are arranged side by side in the figure. The top of the annular cover and cylinder body are connected with the support. There can be more than two tangential air inlets 7 on the upper end of the cylindrical body 6, and there are two air inlets 7 in the figure. There is a short air outlet pipe 8 coaxially arranged in each cylinder and communicated with the bottom hole of the ...

Abstract

The invention discloses a cleaner cyclone-typed secondary dust separating cup, which comprises the following parts: case, vent on the case, inlet contacted peripherial wall of case, separator in the case, baffle lid on the bottom floor under separator, upper end of separator in connection with rack, inlet of separator under ring-shaped lid, cylinder with inlet on two ends of ring-shaped lid, short vent pipe in connection with bottom rack of rack with the same shaft in each cylinder, conical cylinder in the cylinder at lower position than short pipe, separating ring in connection with lower end of conical cylinder with roof connecting rack, ring-shaped gap among periphery of cylinder, floors on two bottoms of baffle ring and cylinder.

Description

technical field [0001] The invention relates to an accessory of a vacuum cleaner, in particular to a dust cup for secondary separation of air and dust in a cyclone type of the vacuum cleaner. Background technique [0002] At present, general vacuum cleaners use the principle of cyclone centrifugation to separate air from dust, and deposit larger and heavier particles at the bottom of the dust cup. This kind of vacuum cleaner with only one separation device has an unsatisfactory separation effect between air and dust, so the fine dust is easily discharged with the air and deposited on the filter, which reduces the dust collection efficiency. For this reason, in order to improve the separation effect, various dust cups equipped with two separation devices have come out one after another. Chinese Patent Gazette discloses application number "200510094505.X", "Dust Separator for Vacuum Cleaner", which consists of a first-stage cyclone separator located upstream and a plurality o...
