The water inlet pipe 24 is also connected to the water pump 10 so that the water pump 10 communicates with the water diversion chamber 211.

The valve core 22 is rotatably assembled on the valve body 21 and driven by the rotary driving device, the switching piece is accommodated in the water diversion cavity, namely, the rotary driving device drives the valve core 22 to rotate, and the rotation of the valve core 22 can synchronously drive the switching piece 221 to swing in the water diversion cavity 211 so as to block the first water outlet pipe 25 or the second water outlet pipe 26. Specifically, the switching piece 221 is configured to block the first water outlet pipe 25 when swinging to block the first water outlet 213 in the water distribution cavity 211, and to block the second water outlet pipe 26 when swinging to block the second water outlet 214.

The water inlet valve 40 is provided with a water supplementing hole 41, and the water supplementing hole 41 is communicated with the first water outlet pipe 25 and/or the second water outlet pipe 26 through a water passing pipeline 42; in this embodiment, only the second water outlet pipe 26 is connected. Specifically, the action of the water inlet valve 40 is triggered by the tank buoy 50, i.e. the lifting of the tank buoy 50 controls the opening or closing of the water inlet valve 40.

Further, in this embodiment, the rotation driving device is a switching pontoon 23, and the switching pontoon 23 is linked with the valve core 22 of the switching valve; the switching pontoon 23 drives the valve core 22 to rotate along with the water level lifting movement, so as to drive the switching piece 221 to swing in the water diversion cavity 211 to block the first water outlet pipe 25 or the second water outlet pipe 26.

The embodiment also provides an intelligent toilet, which comprises a toilet seat and a water tank 30, wherein the flushing system with the pump is arranged in the water tank 30, the first water outlet pipe 25 is communicated with a water channel of a brush ring of the toilet seat, and the second water outlet pipe 26 is communicated with a water spraying channel of the toilet seat.

One of the operation modes in this embodiment is as follows: when the tank 30 is full of water, the tank buoy 50 and the switching buoy 23 are in the highest position, and as shown in fig. 1 and 2, the water inlet valve 40 is in a cut-off (i.e., closed) state; the switching buoy 23 controls the switching piece 221 to block the second water outlet 214 and open the first water outlet 213, namely to block the second water outlet 26, and when in operation, the water pump 10 pumps the water in the water tank 30 into the water diversion cavity 211, then enters the first water outlet 25 through the first water outlet 213, and then flows out from the first water outlet 25 (such as flowing out to a brush ring water channel of the toilet seat); as the water level drops, the positions of the water tank buoy 50 and the switching buoy 23 drop along with the water level, and the lowering of the switching buoy 23 drives the valve core 22 to rotate, so as to drive the switching piece 221 to swing from the second water outlet 214 to the first water outlet 213 until the first water outlet 213 is plugged; during the swing, both the second water outlet 214 and the first water outlet 213 are opened, and thus water flows out from the first water outlet pipe 25 and the second water outlet pipe 26; until the first water outlet 213 is blocked, as shown in fig. 3 and 4, the water flows only from the second water outlet pipe 26.

Simultaneously, when the water tank buoy 50 descends to a certain position, the water inlet valve 40 is triggered to be opened, the water inlet valve 40 starts to feed water, meanwhile, one water flow flows into the second water outlet pipe 26 through the water supplementing hole 41 and the water passing pipeline 42, flows out of the second water outlet pipe 26 to the water spraying channel, and finally supplements water for the urinal of the toilet seat, so that the water level in the urinal reaches a preset height. Specifically, in the operation process, the water pump 10 discharges water in the water tank and makes the water drop to a certain water level, and the water inlet valve 40 stops after the water level is replenished, that is, the water pump 10 stops working before the water inlet valve 40, so that the water inlet valve 40 is adopted to replenish water for the flushed urinal, and the design is ingenious. The volume of the water tank 30 does not need to be increased, so that the water tank 30 can be better miniaturized; the adaptability is stronger.

The vertical rod 231 is assembled on the switching buoy 23 in a lifting manner, so that the position of the switching piece 221 is finely adjusted by adjusting the height of the vertical rod 231 relative to the switching buoy 23, if the switching piece 221 cannot completely block the second water outlet 214 when the water tank is at the full water level, at the moment, the switching piece 221 can be adjusted by adjusting the vertical rod 231 to ensure that the second water outlet 214 can be blocked, and the accuracy of the switching piece 221 is ensured.
