摘要： A cyclonic separation device and a vacuum cleaner including the cyclonic separation device are disclosed. The cyclonic separation device includes a housing and a cyclonic separation device. The cyclonic separation device is provided in the housing to allow dirt in a dust-containing airflow to be separated. The cyclonic separation device includes a first-stage cyclone separator and second-stage cyclone separators located downstream of the first-stage cyclone separator in a flow direction of the airflow. The second-stage cyclone separators surround the first-stage cyclone separator. The first-stage cyclone separator includes an air guide channel and a first-stage cyclone channel surrounding a part of the air guide channel. The dust-containing airflow enters, from the air guide channel, the first-stage cyclone channel for cyclonic separation and then enters the second-stage cyclone separators again through the air guide channel.

摘要： A vacuum cleaner comprising a dirty air intake and a cyclonic separating apparatus connected in series. The cyclonic separating apparatus comprises a plurality of cyclonic separators connected in parallel. The vacuum cleaner further comprises a bleed valve provided upstream of the plurality of cyclonic separators. The bleed valve opens to admit bled air into the plurality of cyclonic separators in response to a drop in pressure in the vacuum cleaner. The bleed valve is also connected to the inlets of the plurality of cyclonic separators via a common plenum.
