  • Patent number: 7716784
    Abstract: A suction port assembly and vacuum cleaner having the same is disclosed. The suction port assembly includes a casing comprising a suction port which draws in dust from a surface being cleaned; a drum brush which is disposed rotatably in the casing, on an external surface of which a plurality of bristles are arranged to shake off dust from the surface being cleaned; and a rib which is disposed at a position close to the drum brush, is mounted in the casing so that its one end is in contact with the bristles, and detaches the dust from the bristles when the drum brush rotates; and wherein the bristles are contacted on a slant relative to the rib to prevent the drum brush from rotating when the casing is pulled towards a user.

  • Publication number: 20020026683
    Abstract: According to the invention, a portable surface cleaning apparatus includes a fluid recovery system, a liquid dispensing system, and a rotatable agitation brush comprising a brush body and having a plurality of pliable agitation elements mounted along the brush body for contacting a surface to be cleaned. The agitation elements include a face extending along a length which is sufficient to draw the face across the surface to be cleaned as the brush body is rotated. The agitation elements are formed of elongated straps of fabric having a roughened or textured face and that can be formed of nylon knit strapping, synthetic felt, polyester velour, the loop portion of a hook-and-loop fastener system, pressed fiber material, microfiber polishing cloth, or reinforced synthetic fabric, or, in the alternative, formed of elongated fabric threads or string having a roughened or textured surface and formed of cotton roping or braided polyester threads.

  • Patent number: 6122798
    Abstract: A dust suction head for use in an electric vacuum cleaner, having an air suction port at the bottom of the head. The head has a brush chamber which accommodates therein a freely rotatable brush having blades that extend along the shaft of the rotational brush. The head additionally has an opening and an air passage connected with the opening for taking in and leading fresh air into the vacuum chamber of the cleaner through the brush chamber such that the fresh air passing through the brush chamber impinges on the blades to accelerate the rotational motion of the blades. Thus, the head can obtain a necessary amount of air to rotate the brush at all times, especially when it is brushing a carpet, and maintain its smooth motion on the floor while dusting it.

  • Patent number: 5611109
    Abstract: A cleaning roller for a suction head has a substantially cylindrical base body with a cylindrical mantle surface. The base body is driven in rotation about an axis of rotation. Support members are connected to the base body and project radially past the cylindrical mantle surface. At least one elongate wiper blade with a shaft is fastened to the support members so as to extend parallel to the axis of rotation. The at least one wiper blade in its working position projects from the base body in the radial direction. The wiper blade is pivotable out of the working position about a pivot axis defined by the shaft. The wiper blade is made of elastic material.

  • Patent number: 5365634
    Abstract: A surface treating tool comprising an interconnected cleaning and stripping device for a self contained automated retrieval cleaning apparatus that provides a vacuum recovery and filtration system, with the tool consisting of a rotary brush mounted in an open bottom housing. The brush provides a core having operative connection to a rotating means and includes rows of radially extending resilient flaps carrying at their distal ends peening elements adapted to have contact through the open bottom of the housing with the surface to be cleaned while such surface is being vacuumed. The core can also provide radially extending wire bristles alternately disposed between the rows of resilient flaps.

  • Patent number: 4733432
    Abstract: A power brush e.g. for a vacuum cleaner or street sweeper has its bristle bodies swivelably mounted on a member which is given an orbital movement so that the eccentric axes of the bristle bodies with respect to their swivel axis induces an additional oscillatory motion of each bristle body as it moves in the orbital path generated by the motion of the member on which its carrier is mounted.

  • Patent number: 4430768
    Abstract: Agitator restrictor structure in combination with a revolving or a reciprocating type sweep drive is located close to the nozzle mouth in a suction cleaner by providing a cavity in the agitator structure for recessing the major portion of the cleaning brush to retain the designed bristle tuft lengths. In this location, the agitator structure restricts and changes the shape of the airstream at the nozzle opening to increase its speed, resulting in greater cleaning efficiency.

  • Patent number: 4221018
    Abstract: An improved lawn sweeper for clearing a lawn of accumulated debris such as leaves, pine straw, and the like is disclosed. The novel sweeper comprises, in the embodiment shown, an open-bottomed housing holding a rotating cylinder having a number of very strong, flexible wire cable sections bolted to the cylinder. The ends of the wire cable sections have formed thereon a section of tubing pressed flat on the outer ends thereof. The wire cables are mounted in pairs on the cylinder with the flat tubing sections being toed in somewhat in relation to each adjacent pair. The rapidly moving blades create a strong updraft to sweep up accumulated debris with the toe in of the pressed flat tubing sections creating a swirling action which tends to enhance the lifting of the moving air. The ends of the wire cable sections are positioned above the ground by an adjustable distance ranging from one (1) inch to three (3) inches.

  • Patent number: 4145791
    Abstract: A hand held lightweight apparatus for cleaning lint and fiber waste from the clearer rolls of spinning frames without removing such rolls from the spinning frame includes a driven, monofilament nylon flail which revolves at high speed within a suction head coupled to a vacuum producing apparatus. The nylon cord extends through an opening of the suction head upon each revolution of the driven flail device and the whipping action tears the accumulated lint and waste from the clearer rolls, while sightly roughening the roll surfaces, and the waste is directed to a collection point.
