A concentrated water outlet 504 is connected to the water inlet passage 200, and the concentrated water outlet 504 is connected to the front end of the first control valve 220 through a water pipe.

The pressurizing structure for pumping the water in the pure water portion 511 to the raw water end 101 includes the following embodiments:

The pure water bubble membrane system comprises the following working modes:

pure water use mode: in this mode, the first control valve 220, the second control valve 410, and the first booster pump 210 are opened, and the third control valve 520 and the fourth control valve 540 are closed. As shown in fig. 2, when a user opens the faucet, raw water enters the reverse osmosis filter element 100 through the water inlet passage 200 and the raw water end 101 to perform a normal filtering operation, pure water formed after filtering enters the pure water passage 300 through the pure water end 102 to be discharged for the user, and generated waste water enters the waste water passage 400 through the waste water end 103 to be discharged to an external environment.

Bubble membrane pure water preparation mode: as shown in fig. 3, when the user finishes using water in the pure water use mode, the water tap is turned off, which corresponds to closing the pure water passage 300. The tap water is continuously supplied to the water inlet passage 200, and at this time, since the pure water passage 300 is closed, pure water obtained by filtering raw water by the reverse osmosis filter element 100 flows into the pure water portion 511 through the pure water end 102 and the pure water inlet 501 to be stored, and waste water generated by filtering is still discharged to the waste water passage 400 through the waste water end 103. Until the pure water part 511 is filled with pure water, the pure water passage 300 is in a high-pressure state, the pressure switch detection device 310 feeds back signals to the whole machine after detecting high-pressure signals of the pure water passage 300, and all valve bodies of the whole system are stopped to enter a standby state.

When the reverse osmosis filter element 100 is not used for a long time, the concentrated water in the reverse osmosis filter element 100 can permeate to the pure water, so that the pure water is polluted.

Pure water bubble membrane mode: as shown in fig. 4, when the system detects that the user does not perform the pure water usage mode for a while, the system opens the third control valve 520, the fourth control valve 540 and the fourth check valve 550, at this time, the first control valve 220 and the second control valve 410 are in a closed state, pure water in the pure water portion 511 is pumped to the raw water portion 101 through the pure water outlet 502, the pure water enters the reverse osmosis filter element 100 to mix with the residual raw water, normal reverse osmosis filtration is performed, concentrated water is recycled to the concentrated water portion 512 through the waste water portion 103, the fourth check valve 550 and the concentrated water inlet 503 in sequence, and the pure water originally remaining in the reverse osmosis filter element 100 is replaced by the newly filtered pure water and recycled to the pure water portion 511.

When the user opened the pure water user mode, open tap, open pure water passageway 300, under the effect of first booster pump 210, the dense water in dense water portion 512 gets into inhalant canal 200, mix with the running water, get into reverse osmosis filter core 100 through first control valve 220 and carry out filtration treatment and use, utilize bubble membrane passageway 500 from circulation pure water bubble membrane mode, need not discharge waste water to outer environment and can reach the purpose of pure water bubble membrane under pure water bubble membrane mode, and solve the too high problem of first cup water TDS value, whole system access control mode is clear simple.

The electric devices of the system, such as the first control valve 220, the second control valve 410, the third control valve 520, the fourth control valve 540, the first booster pump 210, the second booster pump 570, the fourth check valve 550, the pressure switch detection device 310, and the like, can be connected with external electric control components for control.

In some embodiments of the present invention, an elastically deformable water bladder (not shown) is disposed in the water-driven tank 510, and the water bladder divides the interior of the water-driven tank 510 into a pure water portion 511 and a concentrated water portion 512, and the interior of the water bladder forms the concentrated water portion 512. In the pure water bubble membrane mode, when the concentrated water enters the concentrated water portion 512, the volume of the water bladder constituting the concentrated water portion 512 increases, and the pure water in the pure water portion 511 is pumped toward the raw water end 101.

Further, a second check valve 560 is provided between pure water terminal 102 and pure water inlet 501, and pure water is ensured to flow unidirectionally from pure water terminal 102 toward pure water inlet 501 in the bubble film pure water mode and pure water bubble film mode by means of second check valve 560.

Further, the pure water passage 300 is provided with a third check valve 320, and the pure water in the pure water passage 300 is prevented from flowing backward toward the pure water end 102 by the third check valve 320.

In some embodiments of the present invention, the water inlet passage 200 is provided with a composite filter element 230, and the raw water is filtered by the composite filter element 230 before entering the reverse osmosis filter element 100, so as to further improve the water purification effect.

In some embodiments of the present invention, the activated carbon filter 330 is disposed on the pure water passage 300, and in the pure water usage mode, the pure water filtered by the reverse osmosis filter 100 flows into the activated carbon filter 330 for three times of filtration, so as to further improve the water purification effect.

Since the concentrate inlet 503 and the concentrate outlet 504 are operated in different modes, respectively, the concentrate interface 506 realizes single inlet or single outlet of the concentrate in a specific mode.

In some embodiments of the present invention, a pressure reducing valve 202 is disposed at the raw water inlet 201 of the water inlet passage 200; as shown in fig. 1, a pressure reducing valve may be disposed at the rear end of the composite filter element 230, and tap water passes through the raw water inlet 201, is filtered by the composite filter element 230, and is then reduced in pressure by the pressure reducing valve 202 for subsequent treatment.
