A cyclonic separating device includes first and second cyclonic separating units. The first cyclonic separating unit is fitted over the second cyclonic separating unit. The second cyclonic separating unit includes first cyclones and second cyclones respectively arranged in a ring shape. Dust falling ends of the first cyclones define an accommodation space therebetween. The second cyclones partially extend into the accommodation space. Each first cyclone comprises first, second and third cone sections, each of which has a cone structure; airflow sucked in the first cyclones is sequentially separated by the first, second and third cone sections, and dust in the airflow is discharged from the third cone section; a central axis of the first cone section is parallel to a longitudinal axis of the dust cup; and an angle between a central axis of the second cone section and a central axis of the third cone section is 5°-20°.

A cleaner includes a dust bin, a motor housing disposed above and coupled to the dust bin, a handle coupled to the motor housing, a cyclone part disposed in the dust bin and configured to separate dust from air, a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone part, and a compression part configured to compress the dust in the dust bin. The compression part includes an operating part disposed in the motor housing and configured to move in a space between an outer portion of the filter part and an inner circumferential surface of the dust bin, a manipulation part disposed outside the motor housing and configured to be manipulated to move the operating part, and a transmission part that is disposed in the motor housing and connects the operating part and the manipulation part.

A cleaner includes: a suction unit; a suction motor that generates suction force for sucking air through the suction unit and includes an impeller; a dust separation unit that includes one or more cyclone units generating cyclonic flow to separate dust from air flowing inside through the suction unit; a dust container that stores dust separated by the dust separation unit and is disposed under the suction motor; a battery disposed behind the dust container to supply power to the suction motor; and a handle disposed behind the suction motor, wherein a rotational axis of the impeller and an axis of the cyclonic flow vertically extend and an extension line from the rotational axis of the impeller passes through the one or more cyclone units.

A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

Provided is a dust collector of a vacuum cleaner, the dust collector including a dust collecting casing including an air inlet, an air outlet, and a foreign substance discharge port, a cyclone module configured to separate foreign substances by inducing a swirling flow of air drawn in via the air inlet, and a discharge door switchable between an open position in which the foreign substance discharge port is opened and a closed position in which the foreign substance discharge port is closed, wherein the cyclone module includes a fixed part and a rotating part having a rotating state in which it is allowed to rotate with respect to the fixed part when the discharge door is in the open position and a locked state in which it is prevented from rotating with respect to the fixed part when the discharge door is in the closed position.

A cleaner of the present disclosure comprises: a suction part; a main body comprising a body and a body cover for opening and closing the lower side of the body, the body comprising a cyclone part for separating dust from dust masses suctioned through the suction part and a dust container for storing the dust separated by the cyclone part; a handle part coupled to the main body; a filter part disposed inside the body, and filtering air, separated from the dust in the cyclone part; a movable part capable of moving inside the body along a space between the outside of the filter part and the inner circumferential surface of the body; an operation part disposed at the outside of the main body to move the movable part; and a delivery part penetrating through the main body, and connecting the movable part to the operation part.
