[0045] The water inlet joint 2 is connected to the external pipeline. After flushing, when the water level in the water tank is lower than the preset low water level, the inner buoy 72 drops as the water level drops. The drop of the inner buoy 72 drives the connecting rod 8 to move. The movement of the connecting rod 8 drives the swing rod 9 to move. The movement of the swing rod 9 opens the water stop valve core 3. The water in the external water pipe enters the valve body 1 through the water inlet joint 2. The water flows into the valve core cavity 11. The water pressure can lift the anti-siphon component 5 to open the water guide port. The water flows into the water guide cavity 12 through the water guide port, and then enters the water outlet pipe 6 from the water guide cavity 12. The anti-siphon component 5 After being lifted up, the air inlet 41 is closed, so that the water guide cavity 12 is closed, and the water in the water guide cavity 12 enters the water replenishment pipe 42, and the water replenishment pipe 42 is used to provide water replenishment for the toilet to form a water seal; when the water level in the water tank rises to a preset high water level, the inner buoy 72 floats up with the water level rising, and the floating of the inner buoy 72 drives the connecting rod 8 to move, and the connecting rod 8 drives the swing rod 9 to move.
