  • Patent number: 7320719
    Abstract: A filter device adapted for filtering fluids flowing one of into or out of a fluid duct. In one embodiment, the filter device comprises a container having one or more walls, wherein at least one of the walls is at least partially rigid and a first opening and a filter element mounted in the first opening so that the filter element forms at least a portion of one of the walls. The one or more container and the interior face of the filter element define an interior adapted for collecting contaminants in a fluid flowing out of the fluid duct. The container further comprises a second opening adapted for sealingly and removably connecting the filter device to the fluid duct so as to provide fluid communication between the interior of the filter device and the fluid duct, wherein the second opening is further adapted for being closed when the filter device is removed from the fluid duct.

  • Patent number: 7318848
    Abstract: A dust collector is disposed between an intake port and an exhaust port in a vacuum cleaner. Air flows from the intake port into the exhaust port along an airflow path in the dust collector. The dust collector includes a dust-collecting net disposed in the path, and a dust-brushing unit. When air flows from the intake port into the exhaust port, a plurality of dust brushes of the dust-brushing unit rotate to brush the net so as to remove dust from the net. Therefore, air can flow unimpeded through the net.

    Abstract: A vacuum cleaner includes a motor-driven blower for drawing air and a dust-catching unit for separating dust from the air drawn by the blower and catching the dust separated from the air. A receptacle is located between the blower and the dust-catching unit and holds a filter for filtering the air that has passed through the dust-catching unit. An airflow control device is arranged between the filter and the blower. The airflow control device generates a first airflow, which passes through the dust-catching unit and the filter and goes toward the motor-driven blower. The airflow control device generates a second airflow, too, which bypasses the filter, passes through at least a part of the dust-catching unit, and goes toward the motor-driven blower. The part of the dust-catching unit is located downstream of the receptacle, with respect to a direction in which the second airflow goes.

  • Patent number: 7175682
    Abstract: An electric vacuum cleaner is equipped with a dust collection unit (20) that can be detachably installed in the air passage en route from a suction unit to an electric fan of the cleaner. The dust collection unit (20) comprises a dust collecting case (21) for accumulating dust sucked in, a lid member (32) that can be opened to discharge the accumulated dust; and a lock mechanism (clamp lever) (33) for locking the lid member 32 tightly closed. The electric vacuum cleaner is further provided with a lid opening mechanism (lid opening stick (35) for forcibly opening the lid member (32) in cooperation with the lock mechanism locking the lid member. Even when the sealing pressure of the packing is high or when the accumulated dust does not weigh on the lid member because the dust is compacted on the inner wall of the dust collecting case, the lid member can be opened without difficulty to discharge the dust, without opening it by hand. Thus, the user can avoid handling unsanitary dust.

  • Patent number: 7146681
    Abstract: A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters the main suction opening, passes through the cyclonic chamber, and passes to an outlet of the suction source. Particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber.

  • Patent number: 7147683
    Abstract: A valve and trigger cyclically connect a vacuum and a blower to a filter. The valve box has three openings, the first connectable to the vacuum, the second connectable to the blower and the third connectable to the filter. A gate inside the box, biased by the blower and the vacuum toward closing the first opening, is held against the bias by a trigger outside the box to close the second opening. The external trigger intervally operates to release the interior gate to close the first opening and open the second opening. The blower operates only if the trigger is operating. The gate is released once for approximately 1/12 of a cycle interval during each trigger operating interval. A plurality of valves can be combined in a system with one trigger for cyclically sequentially connecting a plurality of filters to the vacuum and the blower.

  • Patent number: RE39473
    Abstract: An upright vacuum cleaner includes an upright housing section and a nozzle base section. A cyclonic airflow dirt and dust separating chamber is defined in the upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle base section and into the cyclonic airflow chamber. The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container that defines the chamber. A main filter element filters residual contaminants from the suction airstream between the chamber and the suction source. An exhaust filter housing includes an airstream suction duct in fluid communication with an outlet of the airflow chamber and an inlet of the suction source. An outlet of the suction source is in fluid communication with an exhaust plenum of the exhaust filter housing.

  • Patent number: RE39595
    Abstract: A vacuum cleaner filter bag retainer includes slots on each side which receive a cardboard plate attached to a filter bag. The plate is slid into the slots of the filter bag retainer such that openings in the plate and bag match with an opening in the filter bag retainer. The retainer is attached to a tank through an opening in the tank, and an inlet fitting extends from outside the tank, through the retainer, and into the bag. The inlet fitting, therefore, prevents the bag from sliding out of the slots in the retainer. A swivel fitting loosely traps the inlet fitting adjacent the filter bag retainer through threads on the swivel fitting and the retainer. The inlet fitting also holds a hose to the inlet fitting.
