And the water in the second cavity 1b is discharged into the water tank 20 through the water through hole 115, so that the water in the second cavity 1b is reduced, and the gravity received by the second pontoon 41 is greater than the buoyancy received by the second pontoon 41 because the water in the water storage cavity 411 flows out from the water drain hole slowly, so that the second pontoon 41 descends, and then drives the link mechanism 5 to open the pressure relief opening of the second back pressure cavity 25, the flow path between the water inlet pipe 111 and the second water outlet channel 23 is conducted, and the water in the water inlet channel 21 flows to the toilet bowl through the second back pressure cavity 25 and the second water outlet channel 23, so that the toilet bowl is flushed. When the water tank 20 is in a continuous drainage state, the water level of the water tank 20 is not stopped to drop, the first pontoon 31 is lowered, the connecting rod mechanism 5 driven at the moment opens the pressure relief opening of the first back pressure cavity 24, and water in the water inlet channel 21 flows to the water tank 20 through the first back pressure cavity 24 and the first water outlet channel 22 to supplement water for the water tank 20. When the water level in the water tank 20 drops to a certain height, the water in the water storage cavity 411 of the second pontoon 41 is discharged, and the buoyancy of the second pontoon 41 is greater than the gravity force due to the buoyancy member 4121, so that the second pontoon 41 is in a floating state, and the link mechanism 5 is driven to block the second back pressure cavity 25, thereby closing the flow path between the water inlet channel 21 and the second water outlet channel 23, and after the second water outlet channel 23 is closed, the flow path between the water inlet channel 21 and the first water outlet channel 22 is opened, so that the second water outlet channel 23 can be ensured to have enough water pressure, and the water entering through the water inlet channel 21 is used for supplementing water to the water tank 20.

The buoyancy member 4121 may be a member with high buoyancy such as foam, and bonded together.

Referring to fig. 6 and 7, in an alternative embodiment, the water inlet valve 10 further includes a delay mechanism 6, where the delay mechanism 6 is installed on the bottom wall of the first cavity 1a, and is used to slow down the water outflow speed of the first cavity 1a, so as to slow down the descent speed of the first buoy mechanism 3, and when the water discharge valve flushes the toilet, the water inlet pipe 111 enters the water to assist in flushing the toilet through the second water outlet channel 23, so that the effect of cleaning the toilet is better.

In this embodiment, in order to improve the cleaning effect of the toilet bowl, the water inlet valve 10 further includes a delay mechanism 6, the delay mechanism 6 is mounted on the bottom wall of the first cavity 1a, when the water discharge valve flushes the toilet bowl, the water level in the water tank 20 at this time is lowered, so that the water in the second cavity 1b is discharged into the water tank 20 through the water through hole 115, and the first pontoon mechanism 3 drives the link mechanism 5 to act, so as to open the pressure relief port, and then the flow path between the second water outlet channel 23 and the water inlet channel 21 is conducted, and then the water coming in the water inlet channel 21 is discharged out of the toilet bowl through the second water outlet channel 23, so as to flush the toilet bowl. Under the action of the delay mechanism 6, the water in the first cavity 1a flows out slowly, so that the descending speed of the first pontoon 31 is slowed down in the early stage of water discharge, the flow path between the first water outlet channel 22 and the water inlet channel 21 is in a cut-off state, the water entering from the water inlet channel 21 cannot be discharged into the water tank 20 from the first water outlet channel 22, the water entering from the water inlet channel 21 is discharged out of the toilet through the second water outlet channel 23, the flushing of the toilet by the auxiliary water discharge valve of the water inlet valve 10 is realized, and the sufficient water quantity for auxiliary flushing of the toilet is ensured.

the delay mechanism 6 comprises a delay valve 61 and a delay pontoon 62, the delay valve 61 is rotatably arranged in the first water passing channel 113, one end of the delay pontoon 62 is movably arranged in the first water passing channel 113, the other end of the delay pontoon 62 extends out of the valve body 2, the delay pontoon 62 is used for movably blocking the water outlet 114, the outflow speed of water in the first cavity 1a is slowed down under the combined action of the delay pontoon 62 and the delay valve 61, and further, the water supplementing of the water tank 20 is not carried out by the first water outlet channel 22 in the earlier stage of the operation of the drain valve, so that more water is used for assisting flushing of the toilet.

In this embodiment, in order to drain the water in the first cavity 1a into the water tank 20, a first water passing channel 113 is formed in the bottom wall of the first cavity 1a, and a water outlet 114 is formed in the bottom wall of the first cavity 1a, so that when the first cavity 1a needs to drain, the water is sequentially drained into the water tank 20 from the first water passing channel 113 and the water outlet 114.

Specifically, in order to slow down the water flowing out of the first cavity 1a into the water tank 20, the delay mechanism 6 includes a delay valve 61 and a delay pontoon 62, and the delay valve 61 is rotatably installed in the first water passage 113, one end of the delay pontoon 62 movably penetrates through the first water passage 113, and the other end of the delay pontoon 62 extends out of the valve body 2, that is, the extension pontoon movably penetrates through the first water passage 113 through the water outlet 114 under the driving force of the water, so that the water outlet 114 can be turned on or off. When the water tank 20 is at the normal water level, under the action of water, the time delay pontoon 62 floats in the first water passing channel 113 and stops the water in the first water passing channel 113 from flowing out of the water outlet 114, so that the water cannot flow out of the water tank 20 through the first water passing channel 113 and the water outlet 114, further the first pontoon mechanism 3 is ensured not to sink, and the flow path between the water inlet channel 21 and the first water outlet channel 22 is ensured to be in a cut-off state. When the drain valve works, the water level in the water tank 20 drops, the time delay pontoon 62 sinks after no water is acted, and does not block the flow path between the first water passing channel 113 and the water outlet 114, so that water is discharged out of the water tank 20 through the first water passing channel 113 and the water outlet 114 in sequence, the first pontoon mechanism 3 sinks, and then the link mechanism 5 is driven to open the pressure relief opening, and the flow path between the water inlet channel 21 and the first water outlet channel 22 is conducted, so that water enters the first water outlet channel 22 from the water inlet channel 21 to be discharged into the water tank 20, and water supplementing to the water tank 20 is realized.

When water enters the water tank 20, the surface of the float member 622 facing the connecting leg 621 covers the water outlet 114 under the buoyancy of the water, so that the water in the first cavity 1a cannot be discharged from the water outlet 114. When the water level in the water tank 20 drops, the hook end 6211 is hooked on the bottom wall of the first cavity 1a, thereby opening the opening to allow water in the first cavity 1a to flow out into the water tank 20. Since the sealing rib is formed on the outer peripheral edge of the valve body 2 near the water outlet 114, the sealing performance of the connection between the float member 622 and the water outlet 114 can be improved when the surface of the float member 622 abuts the water outlet 114.
