  • Patent number: 8220101
    Abstract: A telescopically rotatable mop, comprising: an internal and external rod fitting to each other in a linearly and telescopically movable state; an engaging element positioned within the opening at the top of the internal rod; a driving element formed in an elongated shape and positioned within the external rod in such a way that the driving element is moved up and down synchronically with the external rod; an actuating element positioned within the engaging element for accommodating the driving element, the engaging element being driven in a single direction when the actuating element is rotated by the driving element. An annular element rotatable clockwise and counterclockwise at 360° is mounted on the top portion of the engaging element. The actuating element received within the engaging element has a smaller length, thereby creating a gap for the lifting and lowering purposes. In this way, a more smooth operation with less effort is ensured when the internal and external rods rotate in a telescopic way.

  • Patent number: 8087878
    Abstract: A powerless diversion plate of a ceiling air-conditioning circulation machine includes a bearing block and a bearing within a circular inflow/outflow hole for installing a diversion disc having a plurality of radial separation pieces. A plurality of conic and ring-shaped diversion pieces are positioned around the connection shaft. The diversion disc is separated by the ring-shaped diversion pieces and the radial separation pieces to create air inflow/outflow zones. The diversion disc has a downward protruding middle part and a staged structure at the rim thereof to form a predetermined shape. This obviates a powered motor, as the radial separation pieces of the diversion disc serve as a working surface, and respond to forced air for causing the diversion disc to be driven in 360° rotation to diffuse air downward or suck air upward in a flowing way, thereby enhancing air-outflowing and convection efficiency and reducing energy consumption and carbon release.
