Water-saving toilet flushing apparatus having water saving property

摘要

The present invention relates to a toilet seat comprising a dual flush device for performing both a short flush cycle and a long flush cycle in a toilet tank including a flushing valve operated by an actuating arm, The present invention also relates to a trap passage sealing apparatus for a toilet tank in which a toilet tank includes an overflow pipe and an inflow water control member.;The double washable mechanism includes a cam, and the cam operable as a handle is rotatably supported at a position adjacent to the actuating arm. When rotating in the first direction, the cam presses and pivots the actuating arm to perform long-term flushing. During rotation in the second direction, the cam presses the operation arm to pivot to perform short-cycle flushing. The lever is pivotally supported with respect to the actuating arm and includes a first position in which the blocking of the contact with the actuating arm is released and a second position in which the lever supports the return of the actuating arm for a predetermined time when the cam rotates in the second direction 2 position. The buoy is connected to the lever to determine the predetermined time. When the cam rotates in the second direction, the lever pivots the lever into the second position.;On the other hand, the trap path seal-sealing apparatus includes an end portion slidably supported along the overflow pipe so as to move in accordance with a change in the water level in the tank as the tank is washed and refilled. The water hose for sewing includes a free end connected to the buoy through which water is introduced from the influent water regulator. The water hose for the sewing material selectively directs water to at least one of the tank and the overflow pipe depending on the position of the buoy determined by the vet in the tank.
