An air purifier and a filter cleaner are provided. The filter cleaner is configured to be mounted in an air purifier. The filter cleaner comprises a motor, a cleaning member and a gear mechanism. The motor is configured to drive the gear mechanism to drive a radially outwards facing surface of a cylindrical air filter or a filter holding case past the cleaning member. The air purifier can comprise a polygonal casing and the cylindrical air filter can be located inside the polygonal casing so that a space is formed between the radially outwards facing surface of the cylindrical air filter and the inside corners of the polygonal casing. The filter cleaner can be located in the space between the corner and the filter.

A vapor relief strainer cleaning assembly comprises a turbine and dislodger assembly, wherein the turbine is configured to move a dislodger assembly disposed within a vapor screen relief vessel. Exemplary dislodger assemblies are configured to be powered by vapor or gas and to use excess vapor or gas optionally to dislodge non-condensable contaminants from the filter screen or to facilitate contaminant dislodgement from the inner wall of the filter screen.

An upright two-stage dust collector includes a base unit, a suction blower unit, a filter unit and a dust collecting unit. The suction blower unit has a suction blower body. The filter unit includes a filter body, a coarse particle dust filter cartridge disposed in the filter body, and a fine particle dust filter element disposed in the coarse particle dust filter cartridge. The fine particle dust filter element is coaxially inserted in the coarse particle dust filter cartridge. The air after the first dust collection is filtered by the fine particle dust filter element to perform the second dust collection. Through the combination of the above units, in addition to a two-stage dust collecting effect, the dust collector occupies less space and can be used conveniently.

The present invention relates to a method of implanting a blood clot removal device in a patient's body, by cutting the skin of the patient's body, dissecting an area of the patient's vascular system, placing the blot clot removal device at the dissected area, and connecting a blood flow passageway of the blood clot removal device to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway.

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 method of securing a connecting tube for use in an implantable device for implantation in human or mammal patient, wherein the tube is adapted to move patient fluid or hydraulic treatment fluid from one part of the patient, via the at least one connecting tube to another part of the patient, the connecting tube having a distal end adapted to be located in an organ of the human or mammal patient for drainage of a patient fluid or in a reservoir for movement av hydraulic treatment fluid, from a treatment area of the human or mammal patient into the organ.

An air purifier and a filter cleaner in which the air filter can be placed in its operational position during the cleaning. The filter cleaner is configured to perform mechanical cleaning of the air-filter by making a cleaning member contact the surface of the air-filter for a first period of time, and to perform sterilization of the air-filter by applying UV light on the air-filter for a second period of time.

An agricultural equipment air screen cleaning assembly having a frame having an airflow opening having a non-circular outer perimeter, a screen mounted to the frame within the airflow opening and extending to the non-circular outer perimeter, a motor, and a suction wand operatively connected to the motor and located on an upstream side of the screen. The suction wand is rotatably connected about a rotation axis at a central region of the screen, and includes: at least one distal end that is movable in a radial direction with respect to the rotation axis to follow the non-circular outer perimeter as the suction wand rotates about the rotation axis, one or more inlet openings facing the screen, and an internal suction flow path in fluid connection with the one or more inlet openings, the suction flow path extending from a manifold to the distal end of the suction wand.
