Since the stopper protrusion 4012 of the connecting rod 401 is above the piston 604, at this time, the upward movement of the connecting rod 401 does not drive the piston 604, i.e., the piston 604 maintains the initial state. When the pull rope 501 is pulled to the highest position, the flap cover 402 is loosened, and falls under the action of gravity until the water outlet 301 is closed, and the connecting rod 401 returns to the initial state.
When the hydraulic assembly 60 drains, the pressure water source enters the hydraulic chamber 6012 through the water inlet 602, the piston 604 is pressed to move up and abut against the limiting protrusion 4012, so as to pull the connecting rod 401 to drive the flap cover 402, the sealing element 404 is separated from the base 30 to open the water outlet 301, and the water outlet valve is opened to drain water to the toilet. Since the pull rope 501 is movably connected to the connecting rod 401, the pull rope 501 can only be pulled to drive the connecting rod 401, the connecting rod 401 cannot return to drive the pull rope 501, and at this time, the pull rope 501 maintains an initial state. When the hydraulic chamber 6012 stops the water supply, the piston 604 starts moving down by the spring 605, and discharges the water in the hydraulic chamber 6012 from the gaps 70 between the piston 604 and the cylinder 601 and between the cylinder 601 and the connecting rod 401 until the water discharge port 301 is closed, and the connecting rod 401 returns to the initial state.
The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
