The following will be described with reference to examples:

example 1:

the washing wastewater on the upstairs is collected and guided to the toilet flushing water tank 3053 below the upstairs for storage. Because the electromagnetic overflow valve is normally open, when the infrared curtain does not detect that someone is in the toilet and the water level of the toilet flushing water tank 3053 reaches or exceeds the overflow water level, the wastewater exceeding the overflow pipe 30532 directly overflows to the toilet flushing water tank 3053 at the lower layer, and then overflows and is stored layer by layer; when the infrared curtain detects someone like the lavatory, then open moisturizing solenoid valve 3083 moisturizing, close overflow solenoid valve 3084 simultaneously and stop the overflow, the overflow water level is started to cross by the water tank water level, then cross inverted U-shaped siphon top inflection point, it flows to the lower bottom O venturi tube of water tank, gather here, until being full of the O venturi tube, when the water of gathering in the lower section of the inverted U-shaped siphon on O venturi tube upper portion is enough to overcome the air jacking in the toilet flushing water pipe of O venturi tube lower part, so that towards the groove with the trend of "avalanche", because the effect that the O venturi tube is full of water sealed simultaneously, form the negative pressure in the inverted U-shaped siphon, form 305siphon promptly, the water in the toilet flushing water tank 3 is inhaled fast and is accomplished, the air gets into the inverted U-shaped siphon, the toilet flushing is accomplished.

If the infrared curtain detects that someone is in the toilet and the water level of the water tank does not reach the overflow water level, the water replenishing electromagnetic valve 3083 is opened for replenishing water, the overflow electromagnetic valve 3084 is closed for stopping overflow, when siphon is formed for flushing the toilet, the liquid level sensor 3082 arranged on the O-shaped pipe detects the flushing water level, the power supply of the water replenishing electromagnetic valve 3083 and the overflow electromagnetic valve 3084 is turned off, water replenishing is stopped, overflow is prepared, tap water is saved, and preparation is made for next water storage and flushing.

Someone is like the lavatory, and when the waste water of flushing cistern 3053 storage did not reach the overflow water level, the function of moisturizing solenoid valve 3083 is to supply the siphon flex point with the water level fast, plays the effect of start-up. When someone is in the toilet and the stored waste water does not reach the overflow water level, the water replenishing electromagnetic valve 3083 has the function of quickly replenishing water to the water tank, and the function in the later stage is to quickly replenish the water level to the siphon inflection point to play a role in starting. Therefore, the water replenishing solenoid valve 3083 functions to replenish water and activate the toilet flushing.

Example 2:

4 electro-contact pressure gauges y0, y1, y2, y3 and y3 are provided as pressure sensors 2063 on a municipal water network, and the pressure gauges y2 and y3 are respectively set to 0.35Mpa, 0.34Mpa, 0.3Mpa and 0.15Mpa, respectively, to control whether the first pressurizing pump 202 is started or not. When the municipal water supply pressure is lower than the set parameter of 0.15Mpa, the y3 contact is disconnected, the first pressure pump 202 cannot be started, and the water pump is prevented from idling; when the municipal water supply pressure is higher than the set parameter of 0.15MPa, the y3 contact is closed to prepare for water supply, when the pressure of the pressurized water supply is lower than the set lower limit parameter of 0.3MPa, the y2 contact is closed to automatically switch on the control power supply, the first pressurizing pump 202 is started to pressurize the water supply. The pressure gauges y1 and y3 cooperate to control whether the first pressurizing pump 202 is stopped or not. When the pressure of the pressurized water supply reaches the set upper limit parameter of 0.34MPa or the pressure of the municipal water supply is lower than the set parameter of 0.15MPa, the contacts of y1 and y3 are disconnected, the first pressurizing pump 202 automatically stops rotating, and the pressurization is stopped; the pressure gauge y0 has an overpressure protection function, when the y1 fails, the pressure of the pressurized water supply exceeds the on-line parameter of 0.34Mpa, but the first pressurizing pump 202 does not stop running, and the pressure of the pressurized water supply continuously rises to reach the limit parameter of 0.35Mpa, y0 is disconnected, so that the first pressurizing pump 202 is forced to automatically stop running, and an alarm signal is sent out.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
