The entire flush-assisted flush mechanism 10 is mounted in a tank 40 of a toilet, the tank 40 is disposed at the rear end of the bowl 30, the bowl 30 is a ceramic bowl 30, the tank 40 is embedded at the rear end of the bowl 30, and the top of the tank 40 is flush with the top of the bowl 30 (short tank 40).

The connecting device is a four-way pipe 13, and the switching piece 14 moves under the driving of water flow in the four-way pipe 13. Specifically, the water entering the four-way pipe 13 from the first water inlet port 131 flushes the switching member 14 to the direction of the first flushing port 132, so that the water drain port 133 is communicated with the first inlet port, that is, the water entering the four-way pipe 13 from the first water inlet port 131 flows out from the water drain port 133 to the water drain valve 12; the water entering the four-way pipe 13 from the first flushing port 132 (the water pump 11) flushes the switching piece 14 to the direction of the first water inlet port 131, so that the water discharge port 133 and the flushing assisting port 134 are simultaneously communicated with the first flushing port 132, that is, the water entering the four-way pipe 13 from the first flushing port 132 flows out from the water discharge port 133 and the flushing assisting port 134.

The drain valve 12 is opened by the water flow flowing in through the drain port 133, and when the water level in the water tank 40 reaches a certain level (drain water level), the drain valve 12 can be driven to be closed. The drain valve 12 is connected to the injection pipe 121, water discharged from the drain valve 12 passes through the injection pipe 121 to the injection port 31 of the urinal 30, and water injected from the injection port 31 siphons off dirt in the urinal 30. The water discharged from the drain valve 12 is from the water flowing in from the first water inlet port 131 or the water flowing in from the first water flushing port 132.

In this embodiment, the first water inlet port 131 is connected to an external water source (municipal tap water) through the water inlet valve 21, and the water inlet valve 21 can enter the four-way pipe 13 through the first water inlet port 131 and finally be sprayed into the urinal 30 through the drain valve 12 to flush the urinal 30. The water in the water tank 40 is pumped by the water pump 11 through the first water inlet port 131, and the water entering the four-way pipe 13 through the first water inlet port 131 is finally sprayed into the urinal 30 through the drain valve 12 and the flushing assisting pipeline 15 to flush the urinal 30. Wherein, the water inlet valve 21 is an electric or mechanical double-control water inlet valve 21, namely, when the power is on, the water inlet valve 21 can be started by electric control, and when the power is off, the water inlet valve 21 can also be started by mechanical pressing.

When the power is on, the water pump 11 pumps water in the water tank 40 to enter the drain valve 12 and the flushing-assisting pipeline 15 (the position of the first water inlet interface 131 is sealed and blocked by the switching piece 14), the water flows are simultaneously sprayed into the urinal 30 through the spraying pipeline 121 and the flushing-assisting pipeline 15, and two water flows generate strong impact and can generate strong siphonage, so that dirt in the urinal 30 is washed more cleanly, and meanwhile, the noise is smaller under the same impact effect; when the power is off, the water inlet valve 21 is used for feeding water and entering the four-way pipe 13 and the drain valve 12 through the first water inlet port 131 (the flushing assisting pipeline 15 and the first flushing port 132 are sealed and blocked by the switching piece 14), and the water flow is sprayed into the urinal 30 through the drain valve 12 and the spraying pipeline 121 to flush dirt in the urinal 30. Thus, when the power is on, the flushing-assisting flushing mechanism 10 enables the urinal 30 to be flushed more cleanly under the action of two water flows of the injection pipeline 121 and the flushing-assisting pipeline 15, and when the power is off, the water discharge valve 12 directly feeds water through the water inlet valve 21 to flush the urinal 30, so that the urinal 30 can be flushed when the power is off, the power on and power off double control is realized, and the practicability is strong.
