[0024] Based on the above technical features, by setting the sunken box 2, the upper end surface of the box 2 is flush with the upper end surface of the toilet bowl 1, reducing the space occupied by the barrel body, and by separating the water storage part and the water suction pipe part 3 in the box 2, the box 2 can realize the functions of water storage and water discharge and water absorption while having a simple structure. Through the installation cavity 5, different placement components can be set in the installation cavity 5 according to different needs to achieve control; and through the integrated design, the manufacturing process is simplified. The flushing control of the barrel body is realized by setting the three-way valve, and the tap water fills the water storage tank 4 through the water inlet valve 26. When the water volume reaches the adjusted amount, the water inlet valve 26 closes the water inlet; when flushing, the electronic control board issues a flushing command to control the water pump 27 to shut down / start, and pump the water out of the water tank 4. At the same time, the electronic control board issues a command to control the three-way reversing valve to start the water flow at the set time to start the injection nozzle 18 or the washing nozzle 17 to complete washing, injection siphon flushing, and sewage flushing. When the water level of the water tank 4 sinks, the water inlet valve 26 will open until the water tank is full of water and is ready for the next sewage flushing. Since the tank body 2, water pump 27 and three-way valve reversing valve are sunken, there are not too many requirements for water pressure and flow. As long as the external tap water can enter the sunken water tank and fill it up, flushing and sewage can be carried out. Through the connection and driving action between the water inlet valve 26, water pump 27 and the three-way reversing valve, it is particularly suitable for users with low water pressure and low flow on high floors, which greatly improves the flushing and sewage discharge effect of the smart toilet and achieves a very good water-saving effect.
