The utility model discloses a theory of operation and use flow:

(1) primary water purification: municipal administration running water gets into from the water inlet 18 of water purifier, through the preliminary filtration of the PP charcoal composite filter core of "a membrane shell 17" the inside, large granule pollutants and chemical substances such as rust, impurity, alga, chlorine residue in aquatic are filtered and are clear away, if: the pollution degree of the tap water inlet is calculated according to the numerical value of 500, the numerical value is reduced to 200 through the primary filtration of the 'first membrane shell 17' filter element), the primary purified water with the pollution degree of 200 flows out from the 'first membrane shell 17', and large-particle pollutants are removed through the primary purified water generated after the primary filtration, so that the blockage of a 'precision filter membrane' is effectively reduced, and the service life of the 'precision filter element' is prolonged.

(2) Precise water production: the water purification faucet arranged on the vegetable washing basin is opened, the water pressure of the water purification discharge port 1 is reduced, the water purification discharge port is communicated with the high-voltage switch 2 connected in series with the water purification faucet, the mains supply connected with a lead supplies power to the water inlet electromagnetic valve 15 and the booster pump 16, so that the water pressure and the flow of primary purified water are increased, the primary purified water reaches the water inlet 5 of the second membrane shell 4 through the third tee joint 8, a part of the primary purified water passes through the membrane of the precision filter membrane and reaches the water purification port 13 of the second membrane shell 4 under the action of the water pressure of the precision filter element arranged in the water purification faucet, the part of the primary purified water flows through the first check valve 11, the fourth tee joint 10 and the water purification tank 12, then flows through the third check valve 3 and the high-voltage switch 2 and finally flows out from the water purification discharge port 1, and the part of the precisely filtered purified water (the pollution degree value is reduced from 200 to 0), thoroughly removes the pollutants, and ensures that clean and sanitary purified water continuously flows out of the 'purified water faucet'.

(3) And (3) discharging wastewater: and a part of primary purified water flows out from a water outlet 14 at the position of the second membrane shell 4, the flow is limited by the waste water ratio 7, and finally the waste water is discharged from the waste water outlet 6, so that the waste water amount is compressed by the waste water ratio 7, and the functions of reducing discharge and saving water are realized.

(4) Water purification and backwashing: the water purifying tap arranged on the vegetable washing basin is closed, the precisely filtered purified water is not discharged any more, but is stored in the water purifying tank 12, until the vegetable washing basin is full, the water pressure of the purified water discharge port 1 rises, the high-voltage switch 2 connected with the purified water discharge port in series is disconnected, the mains supply connected with a lead wire stops supplying power, the water inlet channel of the primary purified water entering the second membrane shell 4 by the water inlet electromagnetic valve 15 and the booster pump 16 is closed, the water inlet channel is disconnected due to the closing of the water inlet electromagnetic valve 15, the water pressure at the third three-way 8 and the water inlet 5 is reduced, when the water pressure is lower than the water pressure of the fourth three-way 10 at the water purifying tank 12, the high-pressure water stored in the water purifying tank 12 can only flow out from the second check valve 9 due to the reverse installation of the first check valve 11, and the precisely filtered purified water can only enter from the water inlet 5 of the second membrane shell 4 due to the closing of the water inlet electromagnetic valve 15, continuously takes away fine pollutants (the pollution degree value is reduced to 0), and the pollutants flow out from a waste water port 6 connected with a waste water ratio 7 and are discharged when the pressure at two ends of a second check valve 9 is balanced, and water stored in a water purifying tank 12 stops flowing back, so that the function of backwashing the filter membrane of the second membrane shell 4 by purifying water is realized.
