[0002] In the prior art, the dust separation device of the vacuum cleaner includes a first-stage cyclone separator located upstream, a plurality of second-stage cyclone separators located downstream, and the upstream cyclone separator performs coarse separation of large dust. The second-stage cyclone separators are arranged in parallel, the downstream cyclone separators separate the fine dust, and finally output clean airflow from the airflow outlets of the downstream cyclone separators, and each airflow outlet is connected to the airflow output channel conduit after converging and then enter the vacuum source, and usually the airflow output channel conduit is located outside the upstream cyclone separator, resulting in a long airflow output channel conduit, and the designer needs to arrange the position of the airflow output channel conduit during product design so as to facilitate the connection with the vacuum The source is connected, which leads to the difficulty of the overall shape design and the increase of the volume of the device

Embodiment Construction
[0016] See attached figure 1 , a dust separation device for a vacuum cleaner, comprising a first-stage cyclone separator 20 located upstream and a plurality of second-stage cyclone separators 21 located downstream, and each of the second-stage cyclone separators 21 is arranged in parallel. The first-stage cyclone separator 20 includes a first cyclone cylinder 3, and a first cyclone chamber 1 is formed between the first cyclone cylinder 3 and the dust accumulation cylinder 17, and the first cyclone cylinder 1 A first air inlet 5 is opened on the body 3, and the first air inlet 5 communicates with the first cyclone chamber 1. There are multiple second-stage cyclone separators 21, each comprising a second cyclone cylinder 7, which has a second air inlet 10 on the second cyclone cylinder 7, and the second air inlet 10 is connected to the second cyclone cylinder. The second cyclone chamber 11 in the body 7 communicates with each other, and there is a guide pipe 18 at the central p...

The dust separator of vacuum cleaner includes the first upstream cyclonic separator, and several second downstream cyclonic separators in parallel. The first cyclonic separator is provided with airflow output duct, and the second cyclonic separators are provided with airflow outlets, which are converged before being communicated with the inner cavity of the airflow output duct. The dust collector is inside the first cyclonic separator, so that the airflow output duct does not occupy the separating space of the dust separator and has no influence on the dust separating effect, and the overall volume of the two stages of separator may be reduced to facilitate the communication of the airflow output duct to the vacuum source.
