Abstract: A mop structure of converting vertical linear displacement into unidirectional rotation for dewatering a mop comprises: a lower pipe with the bottom coupled to a mop head and the internal side fixed to a spiral rod; a driving pipe, having an interconnecting hole engaged with the spiral rod for passing the spiral rod and disposed at the internal side of the lower pipe, and a circular upwardly facing ratchet disposed at the top of the driving pipe; a fixing pipe, having a penetrating hole formed at the middle of the fixing pipe for passing the spiral rod and disposed at the top of the driving pipe, a circular downwardly facing ratchet installed at the top inside the fixing pipe and corresponding to the circular upwardly facing ratchet of the driving pipe, such that after the spiral rod is passed out from the penetrating hole, a fixing mechanism is provided for limiting the fixing pipe and the driving pipe on the spiral rod; and an upper pipe, with the bottom fixed to the fixing pipe after the bottom of the uppe

Abstract: An armrest includes a base and an arm support. The base has a connecting portion and an installing portion. A first surface at an end of the connecting portion is opposite to the installing portion. The arm support is adapted to assemble with the base, and the arm support is pivotable with respect to the base. The arm support includes a second surface abutting the first surface, with a cavity defined in one of the first and second surfaces. An engaging member is pivotally received in the cavity in a single pivoting direction from an unlocked position to a locked position. The arm support is fixed to the base in the locked position.

Abstract: A method for breaking the cell walls of microalgae includes cultivating microbes in a cultivating liquid, adding microalgae into the cultivating liquid to mix with the microbes, releasing a hydrolysis ferment from the microbes, hydrolyzing cell walls of the microalgae by the hydrolysis ferment of the microbes to decompose the cell walls of the microalgae into saccharide, and removing the microalgae from the cultivating liquid. Thus, the microbes release the hydrolysis ferment after the microalgae touch the microbes so as to hydrolyze and decompose the cell walls of the microalgae in a moderate manner without breaking the contents of the microalgae so that the contents of the microalgae can be released, absorbed and used completely.

Abstract: A curtain includes a curtain bracket (1) having an end to which a rotation driving device (3) is mounted. The rotation driving device (3) can actuate a curtain reeling drum (4A) to rotate a curtain cloth (7) or actuate a reeling rope device (4) to rotate a curtain cloth or shade (7). A reverse rotation releasing device (5) and a resilience reverse rotation mechanism (14) are connected to the rotation driving device (3). The rotation driving device (3) is comprised of a pull rope rotary disc (3c), a unidirectional clutch device (6) connected to the pull rope rotary disc (3c), and a rewinding spring (3e) mounted between the pull rope rotary disc (3c) and a pull rope rotary disc box (3a). Thus, only one cord is sufficient to control opening of the curtain cloth or shade (7), and reverse rotation of the curtain reel drum (4A) is not adversely affected by the rotation driving device (3). It is convenient to use while avoiding injury to children.

Abstract: An adjusting structure of an armrest of a chair contains a first body having a bottom plate and a fitting tube; a vertically moving mechanism inserted in the fitting tube and including a second body, an actuating member, a controlling member, and a lip; a retaining mechanism including an engaging member and locking panel inserted in the through hole of the second body; a support element fitted onto the fitting tube and including a cutout to receive a pressing member; a resilient element secured in the support element and one end thereof being biased against an inner side of the support element, and another end of the resilient element abutting against the pressing member and the control end of the controlling member, the pressing member being used to compress the resilient element.

Abstract: A sucker attachment device includes a support base, a pivot seat pivotally mounted on the support base, a sucker mounted on the pivot seat, a rotation disk swivelably mounted on the support base, and a receptacle assembly mounted on the rotation disk. The pivot seat has a spherical universal connector pivotally mounted on the support base. The support base has an end portion formed with a spherical pivot recess, and the universal connector is rotatably mounted in the pivot recess of the support base. Thus, when the support base is pivoted relative to the universal connector, the universal connector is rotated in the pivot recess through 360° so that the support base is pivoted relative to the pivot seat to change the angle and direction between the sucker and the receptacle assembly freely.
