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...
