In conjunction with reference to figure 3 and Fig. 4, when water purifier also comprises water tank, water purifier also can comprise hydraulic pressure sensor.Hydraulic pressure sensor is arranged at water tank inside, and hydraulic pressure sensor is connected with pilot circuit by wire.Hydraulic pressure sensor is for measuring the hydraulic pressure value in water tank.Hydraulic pressure value in water tank reflects the water storage water yield in water tank, hydraulic pressure value and water storage water yield correlation.Hydraulic pressure value is higher, and the water storage water yield is more; Otherwise hydraulic pressure value is lower, the water storage water yield is fewer.

In step 808, whether pilot circuit detection hydraulic pressure value is greater than the first hydraulic pressure threshold value.If so, following step 809 is then performed; If not, then following step 810 is performed.

In step 809, pilot circuit controls topping-up pump startup work.

When the hydraulic pressure value of water tank inside is greater than the first hydraulic pressure threshold value, show that water tank can normal water supply, now pilot circuit controls topping-up pump and normally starts work, is undertaken drawing water, supercharging by topping-up pump, filters for filter core.

In step 810, pilot circuit does not start topping-up pump.

When the hydraulic pressure value of water tank inside is less than the first hydraulic pressure threshold value, show that water tank cannot normal water supply, reason may be do not have tap water or water shortage in water tank, now pilot circuit does not start topping-up pump, prevent topping-up pump by the moisture pump of each filter core internal adsorption, the efficiency of impact water processed next time.

In addition, after above-mentioned steps 809, pilot circuit also can perform following steps 811 to step 813:

In step 811, pilot circuit detects hydraulic pressure value and whether is less than the second hydraulic pressure threshold value.If so, following step 812 is then performed; If not, then following step 813 is performed.

Wherein, the second hydraulic pressure threshold value is less than the first hydraulic pressure threshold value.

In step 812, pilot circuit control topping-up pump quits work.

Carry out the process of water processed utilizing the water flowed out from water tank, when the hydraulic pressure value of water tank inside is less than the second hydraulic pressure threshold value, show that water tank cannot normal water supply, reason may be that the water yield in water tank is used up or deficiency, now pilot circuit control topping-up pump quits work, prevent topping-up pump by the moisture pump of each filter core internal adsorption, the efficiency of impact water processed next time.

In step 813, pilot circuit keeps topping-up pump normally to work.

Utilizing the water flowed out from water tank to carry out the process of water processed, when the hydraulic pressure value of water tank inside is greater than the second hydraulic pressure threshold value, showing that water tank supplies water normal, when user does not trigger stopping water processed, keeping topping-up pump normally to work.

In addition, when water source water outlet streamflow regime not first predetermined condition time, pilot circuit obtains the hydraulic pressure value in water tank by hydraulic pressure sensor, and when hydraulic pressure value is greater than the first hydraulic pressure threshold value, control topping-up pump startup work, to achieve at water source cannot normal water supply time, maintained the water normal processed of water purifier by the tap water prestored in water tank, guarantee that user still cannot can take a certain amount of pure water during normal water supply at water source, substantially increase Consumer's Experience.
