[0059] Operations of using the toilet system of the present disclosure are as follows.
[0060] I. In a O position state, the water inlet valve 1 is normally open, the drainage valve 3 is normally closed, the water tank 2 has water stored therein, the vacuum release valve 5 is normally open, the intermediate sewage tank 4 is communicated with the vacuum tank 503, the intermediate sewage tank 4 is in a vacuum state, the pressure release valve 6 is normally closed, the intermediate sewage tank 4 is dis-communicated with the pressure tank 602, the suction valve 7 is normally closed, the intermediate sewage tank 4 is disconnected from the toilet 9, the drainage valve 8 is normally closed, and the intermediate sewage tank 4 is dis- communicated with the sewage discharging pipe 12. One or more second check valves 802 are arranged between the drainage valve 8 and the sewage discharging pipe 12, preventing the sewage in the sewage discharging pipe 12 to flow reversely.
[0061] 2. The system start button is pressed to start flushing. The central controller 13 is connected to the system start button 14.

Since the intermediate sewage tank 4 is in the vacuum state, the atmospheric pressure presses the sewage in the toilet 9 into the intermediate sewage tank 4. The open-close control valve of suction valve 701 can control a speed of opening the suction valve 7 and a period of time that the suction valve 7 remains open.
[0063] 4. After the sewage suction is completed, the sewage discharging starts, and a second flushing is performed at the same time. The water inlet valve 1 is controlled to close again, the drainage valve 3 is controlled to open again, the air bag 201 in the water tank 2 is pressurized again, the water is pressed to be drained, and the second flushing is performed. A small amount of water is left in the toilet 9, forming a water seal and facilitating a second use. At this moment, the vacuum release valve 5 remains closed, the suction valve 7 is controlled to reset to close, the toilet 9 is dis-communicated with the intermediate sewage tank 4, and the drainage valve 8 is controlled to open. At this moment, the pressure release valve 6 is controlled to open, the gas in the pressure tank 602 enters the intermediate sewage tank 4, and the intermediate sewage tank 4 is pressurized to discharge the sewage.
[0064] 5. Resetting is started. The water inlet valve 1 is controlled to reset again to open, the drainage valve 3 is reset again to close, the air bag 201 in the water tank 2 is de-pressurized again, the water tank 2 stores water again, and at this moment, the suction valve 7 remains closed, the pressure release valve 6 is controlled to reset to close, the pressure tank 602 is dis- communicated with the intermediate sewage tank 4, the drainage valve 8 is controlled to reset to close, and the intermediate sewage tank 4 is dis-communicated with the sewage discharging pipe 12. At this moment, the vacuum release valve 5 is controlled to reset to open, the intermediate sewage tank 4 is communicated with the vacuum tank 503, the vacuum tank 503 quickly provides the vacuum compensation to the intermediate sewage tank 4, and the intermediate sewage tank 4 is in the vacuum state. At this stage, the system reset is completed, and the system can wait to be used in a next time.
[0065] The above shows only examples of the present disclosure, but does not limit the technical features of the present disclosure. Any simple variations, equivalent substitutions or modifications based on the present disclosure to achieve substantially the same technical effect are covered by the scope of the present disclosure.
