A cleaning mechanism, a cleaning device, and an air conditioner are disclosed. The cleaning mechanism is configured to remove dust of an member object to be cleaned, and includes a dust suction member and a switch member. The dust suction member is movable in a reciprocating manner with respect to a surface to be cleaned of the object, and is provided with at least two separate dust suction chambers each having a dust suction port. In an extension direction of the dust suction chambers, a projected length of the dust suction port on the surface to be cleaned is smaller than the length of the surface to be cleaned. Each of the dust suction chambers is configured to communicate with a fan, and the switch member selectively communicates the fan with one of the dust suction chambers.

A dust collector capable of recollecting the particulate dust is disclosed. The dust collector comprises a collector body having a dust collection tube, a dust collection barrel, a filter barrel which comprises a filter net and an air conduit with one end connected to the inner portion of the filter barrel and another end formed into an air outlet adaptor, a dust clean device and an air suction unit which drives the air with particulate dust to pass the filter net and a cover used to either close or open the air outlet adaptor. When the particulate dust has been accumulated on the filter net more than a preset volume, the dust collector will start to operate its clean maintenance process. The cover will be uncovered from the air outlet adaptor and one end of the dust collection tube will be fixed onto the air outlet adaptor.

A method for removing residual filter cakes that remain adhered to a filter after typical particulate removal methodologies have been employed, such as pulse-jet filter element cleaning, for all cleanable filters used for air pollution control, dust control, or powder control.

A filter assembly for a gas turbine system includes a filter element configured to remove entrained particles from air which passes through the filter element in a first direction toward a central air passageway. A motion generator arranged to rotate the filter element about a longitudinal axis extending in an airflow direction of the air passageway to cause particles accumulated on the filter element to fall downwardly away from the filter element due to gravity.

A filter cleaning device has an improved structure which is capable of effectively cleaning dust in a filter used in an air conditioner. The filter cleaning device includes: a filter; a brush unit movably installed at one side of the filter to separate dust from the filter; a brush movement unit configured so that the brush unit is movable along the filter; and brush guides installed at two sides of the brush unit to guide a movement of the brush unit. Each of the brush guides includes: a first guide groove formed so that the brush unit is moved to be in contact with the filter; and a second guide groove formed so that the brush unit is moved to be separated from the filter.

A device is provided that provides an unbiased filtration effect and an effect of removing captured substances through backwashing by causing a fluid to uniformly pass through a filter element over the entire length in an axial direction at the time of backwashing so as to efficiently rotate a captured-substance removal tool in a filtration unit 1 which includes the captured-substance removal tool 20 axially supported inside the tubular filter element 2 to be rotatable.

A filtering device for removing particles from a bodily fluid of a patient is disclosed. The device is implantable in the patient's body and comprises a tube forming a main fluid passageway for bodily fluid, through which the bodily fluid passes when the tube is implanted, wherein the tube is sized and adapted to be fluidly connected to the bodily fluid. The device further comprises a filter connected to the tube, and a filter cleaning device for cleaning the filter.

A dust removal device includes: an upper cover, a base, a support body, and a dust collector. The support body couples with the upper cover and the base. The dust collector includes: a first connecting member, a second connecting member, and a dust collecting body. The dust collecting body is coupled with the first connecting member and the second connecting member and has a folded structure. When an external force enables a shape of the first dust collecting body to be changed, a distance between the first connecting member and the second connecting member is also changed. In a cleaning mode, the dust collecting body is stretched and compressed in a reciprocating manner by using a structure of the dust collecting body.

Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing and an annular filter assembly, wherein the filter assembly is located inside the housing and comprises a filter material. The filter material may be, for example, an electroformed nickel screen having a smooth working surface and expanding pores. A rotating cleaning assembly comprising a distributor and wipers may be located inside the filter assembly.

A filter assembly for a dryer appliance is provided. The filter assembly includes a filter medium rotatably mounted within a filter cassette that is removably received within a filter slot of the dryer appliance. The filter medium has a first portion and a second portion that are selectively exposed to a stream of exhaust air from the dryer appliance to extract lint. While one portion is filtering lint, a lint removal system removes the lint from the other portion collected during the prior cycle. After each cycle, a motor is configured for rotating the filter medium to expose the clean portion of the filter. The filter cassette is removably received within the filter slot using a magnetic latching mechanism, a securing cover, or another suitable mechanism. A scrubber mechanism may also be used to remove stubborn lint.
