In order to form a full water column as much as possible in the communication pipe 30, in the present embodiment, the water seal 40 is provided in the communication pipe 30 near one end of the inlet 11 of the toilet body. Specifically, the communication pipe 30 includes a vertical pipe section 31 and a pipe section 32 with a U-shaped structure, which is connected to the lower end of the vertical pipe section 31 in a sealing manner, the U-shaped structure forms the water seal 40, please refer to fig. 3, and the water seal 40 has a water seal cover L. The inlet at the upper end of the vertical pipe section 31 is communicated with the water outlet 21 of the water tank, and the outlet of the pipe section 32 with the U-shaped structure is communicated with the water inlet 11 of the toilet body. The outlet of the U-shaped pipe section 32 is sealed from the inlet 11 of the toilet body by a sealing member 80, preferably a bellows seal 80. It is understood that the communication channel 30 may be formed by integral molding.
In this embodiment, the water tank 20 is further provided with an overflow pipe 50 communicated with the communication pipe 30, the overflow pipe 50 is arranged on a drain valve 70 arranged in the water tank 20, an inlet 51 of the overflow pipe 50 is communicated with an inner cavity of the water tank, an outlet 52 of the overflow pipe 50 is communicated with a drain outlet 21 of the water tank, and when the water tank is in a non-overflow state, the inlet 51 of the overflow pipe 50 is positioned above a normal water level of the water tank. The flushing structure further comprises an on-off device 60, wherein the on-off device 60 controls the communication between the overflow pipeline 50 and the inner cavity of the water tank 20 when the water tank 20 is in an overflow state, and the on-off device 60 cuts off the communication between the overflow pipeline 50 and the inner cavity of the water tank 20 when the water tank 20 is not in the overflow state. Through setting up on-off device 60, can guarantee overflow pipe 50's normal overflow function, can avoid again when normal use the air from overflow pipe 50 flow in communicating pipe 30, ensure that communicating pipe 30's the water function of reserving in advance is reliable, simple structure.
Specifically, the on-off device 60 includes a floating barrel 61 and a sealing cover 62 linked with the floating barrel 61, the floating barrel 61 moves up and down along with the water level in the water tank 20 to drive the sealing cover 62 to be in sealing fit with or separated from the top end opening 51 of the overflow pipeline 50, and the top end opening 51 of the overflow pipeline 50 is the inlet 51 of the overflow pipeline 50.
