As shown in figures 1 and 2, in the use of the novel box type non-negative pressure water supply device, the rest use processes and methods of the box type non-negative pressure water supply device body are consistent with those of the existing box type non-negative pressure water supply device. Tap water enters the water tank 101 through the electromagnetic valve 41 with the valve core opened for storage (the tap water does not flow into the water tank 101 after being full), during operation, the tap water simultaneously enters the flow stabilizing tank of the box type negative pressure-free water supply device body (no negative pressure flow controller ensures that no negative pressure is generated in the flow stabilizing tank), the control system controls the booster pump connected with the flow stabilizing tank to work, the water in the flow stabilizing tank is pumped out and pressurized to enter a user pipeline, the pressure sensor arranged at the side of the user pipeline monitors the water pressure in the user pipeline in real time and outputs the water pressure to the control system, when the water pressure is too high, the control system controls the booster pump to lose power, when the water pressure is too low, the control system controls the booster pump to be powered, thus, under the premise that enough. When the water consumption peak and the water supplied by tap water are pressurized by the booster pump connected with the steady flow tank and the water consumption in the water consumption area cannot be met, the control system can control the booster pump connected with the water outlet end at the lower part of the water tank to be powered on to work, so that the water in the water tank 101 enters the user pipeline side through the second electromagnetic valve 42 opened by the valve core, and the normal water consumption of a user is ensured.

As shown in fig. 1 and 2, after the 220V ac power supply enters the regulated power supply a, the regulated power supply a outputs a stable 6V dc power supply at pins 3 and 4 under the action of its internal circuit, and enters the two terminals 1 and 2 of the power supply input of the time control switch a1, so that the time control switch a1 is in a power-on working state. After the time switch a1 is powered on, under the action of its internal circuit and the 3 and 4-pin output power supply time set by the technician, power supply with a certain time is output at certain time intervals to enter the two ends of the power supply input of the electromagnetic valve DC and DC1 and the two ends of the power supply input of the control circuit (for example, 5-day power supply output at 3 o' clock in the evening). In a certain time period when the electromagnetic valves DC and DC1 are powered on to work at certain intervals, the electromagnetic valves DC and DC1 are closed when the electromagnetic valves DC and DC1 are powered on to work for 5 minutes at intervals of 5 days and 3 night, so that tap water does not enter the water tank any more, and water in the water tank does not flow out of the water tank any more. After the control circuit is electrified to work, the singlechip A2 outputs a low level for 5 minutes from a first low level output end 18 pin under the combined action of a peripheral element resistor R (reset), a crystal oscillator BX (provide a clock signal) and an electrolytic capacitor C (power supply filter), the low level is amplified by PNP triode Q1 power and enters a positive power input end of a relay J1 through phase inversion, then, the relay J1 is electrified to attract two control input contacts of the relay J1 to be respectively closed with two normally open contacts, because the two poles of the 220V power supply and the two control input contacts of the relay J1 are respectively connected through wires, two normally open contact ends of the relay J1 are respectively connected with two ends of the power input of the water pump M through wires, and therefore, the relay J1 is electrified to attract two control input contacts of the relay J1 to be respectively closed with the two normally open contacts, and the water pump M can be electrified to. When the pin 18 of the first low level output end of the singlechip A2 outputs a low level signal, after 10 seconds, the singlechip A2 outputs a low level of zero 50 seconds for 4 minutes from the pin 19 of the second low level output end, the low level enters the positive power supply input end of the relay J2 through the power amplification and phase inversion of the PNP triode Q2, and then the relay J2 is electrified to pull in the control input contact and the normally open contact to be closed; because the positive power supply input end of the electromagnetic valve DC2 is connected with the normally open contact end of the relay J2 through a lead, after the relay J2 is electrified to attract the control input contact and the normally open contact of the relay J2 to be closed, the electromagnetic valve DC2 can be electrically operated as a valve core to be opened. Through the aforesaid, this novel every interval 5 days, 3 point water pump M in the dark night can be got electric work 5 minutes, and solenoid valve DC2 gets electric case and opens zero 50 seconds 4 minutes. After the water pump M is electrically operated, water in the water tank 101 is pumped and pressurized and is sprayed out from the water spray holes 71 at the lower ends of the plurality of flushing pipes under high pressure, high-pressure water flow spraying cleaning is performed on the bottom in the water tank 101, and the flushed impurities are discharged through the electromagnetic valve DC2 with the valve core opened. In this is novel, solenoid valve DC2 postpones 10 seconds work because when just beginning, the bottom impurity needs the certain time in the water tank is fallen in the water jet, just begins solenoid valve DC 2's case and just opens, can let the clear water flow out, leads to unnecessary water source extravagant. In this application, the water pump output pressure water, when the bottom in the flush pipe 7 flush tank 101, the water that contains impurity is discharged from the lower part in the water tank in step, and the time of 5 minutes is enough to discharge the waste water that the bottom impurity produced in the water tank (follow-up less time, for example 10 seconds, what the water pump sprayed is the clear water, reaches effective discharge waste water). It should be noted that, the time of the control and control circuit of the time controlled switch a1 and the time of the electromagnetic valves DC and DC1 are not fixed, and the user can set the time as required, for example, the power time outputted by the time controlled switch a1 is 3 minutes, so the total working time of the water pump M and the electromagnetic valve DC2 will not exceed 3 minutes, and in any case, the lower part of the water tank can be flushed clean in the required time period (the first time the user can observe how much time the waste water after flushing can reach the cleaning state, and the power output time of the time controlled switch can be set subsequently). In this is novel, time switch A1's 3 and 4 feet do not export the power after, solenoid valve DC, DC1 and control circuit all no longer work, and initial condition is got back to the circuit, and like this, initial operating condition has just also been got back to box no negative pressure water supply installation body, for the bottom is ready in the flush tank of next time.
