Abstract
A vacuum cleaner having two stages of spiral separation structures is provided. The vacuum cleaner having two stages of spiral separation structures includes a first-stage spiral separator, a second-stage spiral separator, a first dust collection assembly and a second dust collection assembly. The first-stage spiral separator and the second-stage spiral separator are sequentially connected and arranged between a dust collection inlet and a filtering structure of the vacuum cleaner along a gas flow direction. A first spiral channel uses the principle of centrifugal force to separate relatively large and heavy particles in airflow for the first time, and the separated particles fall into the first dust collection assembly to complete the first particle separation and collection.

A vacuum cleaner having two stages of spiral separation structures, comprising a first-stage spiral separator, a second-stage spiral separator, a first dust collection assembly and a second dust collection assembly, wherein the first-stage spiral separator and the second-stage spiral separator are sequentially connected and arranged between a dust collection inlet and a filtering structure of the vacuum cleaner along a gas flow direction;
- wherein the first-stage spiral separator comprises a first spiral channel for driving airflow entering from the dust collection inlet to separate particles for the first time;
- wherein the first dust collection assembly communicates with an outlet end of the first spiral channel for collecting particles generated by separation for the first time;
- wherein the second-stage spiral separator comprises a second spiral channel for driving the airflow after separation for the first time to separate particles for the second time;
- and wherein the second dust collection assembly hermetically communicates with an outlet end of the second spiral channel for collecting particles generated by separation for the second time.
