Apparatus for separating dust from vacuum cleaner

Abstract

A dust separator unit of vacuum cleaner is composed of an upstream inertial separator with less energy consumption and a downstream cyclone separator in which part of said upstream inertial separator is extended.

Description

technical field [0001] The invention relates to a dust separating device on a vacuum cleaner. Background technique [0002] In the prior art, the dust separation device on the vacuum cleaner usually includes a two-stage separator, such as the equipment provided by the invention patent 01807570.3, which includes an upstream cyclone separator and a plurality of downstream cyclone separators, and the air flow is between the upstream cyclone separator and the downstream cyclone separator. Cyclone separation is carried out in the separator, so that the dust is separated from the air flow, and in order to make the structure of the whole device compact, the downstream cyclone separator is inserted in the upstream cyclone separator. But this kind of setting including two-stage cyclone makes it consume more energy in the process of separating dust, so the power of the correspondingly set motor is also larger, resulting in higher cost of use, and due to the ...

AI Technical Summary

Problems solved by technology

But this kind of setting including two-stage cyclone makes it consume more energy in the process of separating dust, so the power of the correspondingly set motor is also larger, resulting in higher cost of use, and due to the upstream cyclone separator The cylinder must be designed to be roughly cylindrical, so the entire product is mainly cylindrical, which limits the shape design of the entire product
