Problems solved by technology

[0002] The dust separation device on the existing vacuum cleaner usually includes a first separator and a downstream separator, wherein the downstream separator is a cyclone separator, and the dusty airflow is roughly separated in the first separator, so that the large ash is separated, The airflow entering the downstream separator is separated with high efficiency, so that the fine dust is separated. Since the separation efficiency of the first separator is low, the separation burden of the downstream separator is heavy, and because the separation in the first separator All the airflow after the large ash enters the downstream separator, so the flow rate of the airflow entering the downstream separator is relatively large, which makes the effect of cyclone separation in the downstream separator poor, resulting in low dust filtration efficiency of the entire dust separation device

Abstract

The dust separator of vacuum cleaner includes the first separator, and one cyclonic separator. The first separator includes one upstream dust chamber with dusty wind inlet and one airflow distributing chamber with the first airflow outlet, the second airflow outlet and the first filter in the second airflow outlet. The cyclonic separator has one cyclone inlet communicated with the first airflow outlet and one cyclone outlet. Partial airflow after separating large grain dust in the first separator flows out directly from the second airflow outlet, and this reduces the quality of airflow entering the cyclonic separator, raises the cyclonic separating effect and increases the airflow quality of the whole separator.
