Abstract:
A cyclone-separator vacuum cleaner, comprising: a main body (1), a suction motor (11), a dust container (2), and a suction inlet base (3). The dust container (2) comprises a container body (21), a container cover (22), and a container base (23). A container air inlet is provided on top of the container body (21). The dust container is provided with a plurality of cyclonic separation conical frustums (24). A tangential air inlet tube (242) is provided on the cyclonic separation conical frustum (24). Openings are provided at the top end and the bottom end of the cyclonic separation conical frustum (24), with the top opening larger than the bottom opening. The top opening of each of the cyclonic separation conical frustum (24) communicates, via a central air channel, with the air inlet of the suction motor (11). An air outlet of the suction motor (11) communicates with an external air discharge outlet provided on the main body (1). A filter frame (221) is provided within a closed air channel, and an air inlet sponge (222) is provided on the filter frame (221). The present invention provides an air channel with a reasonable structure and can achieve effective dust separation and collection. The invention offers strong suction capacities and excellent filter effects to ensure the cleanliness of discharged air. The invention is further provided with an anti-collision function and good cleaning capabilities for relatively inaccessible areas such as baseboards, thereby providing good overall functions. The invention also has good overall stability and low noise.
