  • Patent number: 9981214
    Abstract: A vacuum filter backflushing system having an air recapturing adapter coupled to a vacuum motor's air exhaust port which recaptures a portion of exhaust air and introduces the air into a recaptured air passage. The recaptured air passage is coupled to an air flow director which is configured to direct air to an air filter. The air flow director is configured to selectively prevent air from flowing through the filters in a normal air flow direction and allow the air in the recaptured air passage to backflush the filter by dislodging particles from air filter media. The recaptured air passage can terminate after a last air filter, such that the recaptured air passage is pressurized, or the recaptured air passage can recouple back into the air exhaust port or the air recapturing adapter, such that the air is in constant motion in the recaptured air passage.

  • Publication number: 20150143658
    Abstract: A robot cleaner that sweeps dust on the floor toward its center and absorbs the dust through a small-area inlet with a strong suction force, by a cleaning tool that integrates functions of side brushes and a main brush into one. The present disclosure also provides a robot cleaner that enables a large-diameter foreign material to be guided to and effectively absorbed through the inlet without interference by a cleaning tool. The robot cleaner includes a main unit including a fan motor and a dust collector and having an inlet arranged on a base to absorb foreign materials, and a cleaning tool arranged in the bottom of the base, extending to a front side of the base from the inlet and guiding a foreign material on a floor to a side of the inlet, wherein the cleaning tool is arranged to be movable by an external force.

  • Patent number: 9027202
    Abstract: Highly efficient particulate collectors, such as for dust and street debris collected by a mobile street cleaning vehicle, with very low pressure loss are disclosed. One embodiment uses a specially contoured passage to separate the solid particles from particulate-laden gas stream by rapid directional change at a throat region. By using the Venturi effect at the accelerating zone communicating with a gas return channel from the particulate retaining chamber, a small amount of the gas will be recirculated from the deposit zone to help move and retain the separated particles in a confined collection receptacle.
