Separator and dust suction device

Abstract

The invention relates to a separator and a dust suction device. The dust suction device comprises the separator, the separator comprises a first separating body and a second separating body, the first separating body is provided with a first inner cavity and a first inlet communicating with the first inner cavity; the second separating body is arranged in the first inner cavity, a separating cavity is formed between the second separating body and the first separating body, the second separating body is provided with a second inner cavity and a second inlet communicating with the second inner cavity, and the second inlet communicates with the separating cavity. According to the separator, a mixture of gas and dust particles enters into the separating cavity through the first inlet of the first separating body firstly, the dust particles with the large mass and density are separated from air, thus first-level separating is realized, and the dust particles with the small mass and density enter the second inner cavity through the second inlet located in the second separating cavity from the separating cavity to be further separated. The separator can separate the mixture of the gas and the dust particles layer by layer, and is good in separating effect.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a separator and a dust suction device. Background technique [0002] With the continuous improvement of social economy and consumption level, users have higher and higher requirements for vacuum cleaners. At present, the separator used to separate gas and dust in vacuum cleaners generally has the problem of poor separation effect, which will cause dust to enter the motor and affect the service life of the motor; more seriously, the motor does not have the ability to filter dust, and the dust passing through the motor will eventually It will be discharged to the outside world, causing pollution to the environment and affecting human health. Contents of the invention [0003] Based on this, it is necessary to provide a separator and a dust suction device with good separation effect. [0004] Its technical scheme is as follows: [0005] A separator, comprising: a first ...
