  • Dual control mode-type deodorising and water drainage valve
    Patent number: 9650774
    Abstract: The invention relates to an improved dual control mode-type deodorising and water drainage valve. The water drainage valve includes a linear control water drainage mechanism and a hydraulic water drainage mechanism controlled by a micro-immersible pump. The linear control water drainage mechanism includes a piston with the piston being partitioned into an upper and lower chamber by a central partition plate; the upper chamber is a piston control chamber for controlling the resetting of the piston, and the linear control water drainage mechanism controls the upward action of the piston; and the lower chamber is a water drainage fluid chamber for creating water pressure on the piston. More than one through hole is provided in the central partition plate to communicate with the upper and lower chambers partitioned by the central partition plate.
