The present disclosure includes a first housing configured in a cylindrical shape, an inlet port provided to the first housing to suck air therein, an inlet pipe communicating with the inlet port and extending to a front side of the housing with a length-directional axis positioned side by side with a ground surface, a cyclone forming part provided to separate dust from air flowing into the first housing, a second housing communicating with the first housing and coupled to a rear side of the first housing, a fan provided with the second housing to provide a suction force to enable air to be sucked into the first housing through the inlet port, a battery provided to supply power to the fan, and a handle part including a handle base coupled to a top side of the first housing and a handle body connected to the handle base.

A wearable vacuum cleaner includes a harness configured to support the wearable vacuum cleaner on a user's back, a housing connected to the harness, a suction motor assembly disposed within the housing and operable to create a working airflow, and a collection bin configured to receive debris separated from the working airflow. The collection bin includes an opening adjacent a bottom portion of the collection bin and a lid moveably coupled to the collection bin to selectively cover the opening in a closed position and uncover the opening in an open position. The lid is movable to the open position to empty the contents of the collection bin through the opening while the collection bin remains attached to the housing.

A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member has an outer wall wherein at least a portion of the outer wall is porous and a plurality of ribs spaced around the outer wall. The ribs have a radial outer side that is positioned radially outwardly of the outer wall.

A surface cleaning apparatus has a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber. The cyclone chamber has a sidewall extending from a first end to an axially opposed second end. A dirt outlet communicating with the dirt collection chamber is provided in the sidewall at a location intermediate the first and second ends of the cyclone chamber.

A method for controlling operation of a dust extractor, the method comprising; obtaining (S1) sensor data (235) related to an airflow (240) into the dust extractor, determining (S2) if the dust extractor is operating in a high airflow operating range based on the sensor data (235), and if the dust extractor is operating in the high airflow operating range, controlling (S3) a fan motor (210) of the dust extractor to reduce the airflow (240) to a reduced flow level (330, 3301) at or above a pre-determined airflow level (340) and below an obtainable flow level (310), wherein the pre-determined airflow level (340) is associated with a dust extraction capability of the dust extractor (100).

A separation structure for a dust cup of a vacuum cleaner is provided and includes a cyclone separator. The cyclone separator is provided with a connecting ring, a plurality of arc blades, a plurality of flat plates, a conical tube and a cylindrical tube. Each arc blade has a top fixedly connected with the connecting ring and a bottom fixedly connected with a respective flat plate. The flat plates are fixedly mounted at a large end of the conical tube. A plurality of air inlets are formed by gaps defined by the connecting ring, the arc blades and the flat plates. The cylindrical tube is fixedly connected with and communicated with the conical tube. A small end of the conical tube is received in the cylindrical tube. An included angle between each arc blade and the respective flat plate is an obtuse angle.

A separation structure for a dust cup of a vacuum cleaner is provided and includes a main body and a separator. The separator is fixedly mounted in an internal space of the main body. The internal space of the main body is divided by the separator into a first chamber, a second chamber and a third chamber. The separator is provided with a through hole, an air intake portion and a plurality of sedimentation portions communicated with the air intake portion. The plurality of sedimentation portions are arranged around the air intake portion. A length of the air intake portion is smaller than a length of each of the plurality of sedimentation portions. The air intake portion is communicated with the second chamber, the plurality of sedimentation portions are communicated with the third chamber. The first chamber is communicated with the second chamber via the through hole.

A vacuum cleaner separation system having: a cyclone tube having a cyclone chamber and an inner wall having a substantially cylindrical appearance defining a center axis; an inlet channel offset with respect to the center axis for receiving dust laden air; a dust outlet for discharging dust from the cyclone tube; an air outlet for discharging air from the cyclone tube; and a helical member arranged within the cyclone tube in an opposite region of the cyclone tube with respect to the air outlet. The helical member defines or partly defines a helical passage around the center axis from the inlet channel to the cyclone chamber for generating a centrifugal flow in the cyclone chamber. The helical passage has a substantially constant cross sectional area and the helical passage is rotated 360° or less than 360° around the center axis.

A surface cleaning apparatus has a housing defining at least part of a cyclone chamber and a pre-motor filter chamber. In one embodiment, the housing is pivotally mounted to the main body of a hand vacuum cleaner. The housing is moveable between an in use position and an emptying position, in which the cyclone chamber and the pre-motor filter are concurrently openable.
