Abstract: A handheld vacuum cleaner includes a dust cup assembly, a suction nozzle assembly and a handle assembly. The dust cup assembly includes a cup casing, an airflow generation device and a cyclone separation device, both of which are arranged in the cup casing, the airflow generation device being arranged above the cyclone separation device and positioned on a downstream side of the cyclone separation device, and an air vent being formed in a top of the cup casing. The suction nozzle assembly is mounted to the cup casing and defines a suction channel. The handle assembly is mounted to the cup casing and used to be held. With the structure, a blowing direction of the air vent is not towards a surface to be cleaned, so as to prevent the wind from the air vent blows away dust on the surface to be cleaned and hence ensure a cleaning effect.

Abstract: 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.
