In this embodiment, one end of the return line 700 is connected to the raw water line 300 between the first control valve 310 and the pressure boosting device 320.

This water purification waterway system has several usage patterns, specifically as follows:

and (3) a normal water making mode: as shown in fig. 3, when the user turns on the first water intake switch 410, the pressure detection device 430 obtains a water pressure release signal of the pure water pipeline and feeds the signal back to the controller, and the first control valve 310 and the booster pump are activated by the signal, at which time the second control valve 610 and the third control valve 710 are in a closed state. Tap water enters the water storage container 100 for storage, and under the pumping action of the pressurizing device 320, water in the water storage container 100 is conveyed to the raw water pipeline 300 through the water outlet 120. The water in the raw water pipeline 300 enters the reverse osmosis filter element 200 through the raw water inlet 210 for filtration, and the raw water is filtered to obtain pure water and concentrated water. Pure water enters the pure water pipeline through the pure water port 220, finally flows through the first water intake switch 410 and is discharged for users. The concentrated water flows into the concentrated water pipeline through the concentrated water port 230, the concentrated water flows back into the water storage container 100 through the concentrated water pipeline and the water return port 130, and the concentrated water and the raw water in the water storage container 100 are mixed and diluted. Since the water inlet 110 and the water outlet 120 are adjacent to each other and the water return opening 130 and the water outlet 120 are far away from each other, raw water which is not mixed with concentrated water is preferentially used when water is discharged from the water outlet 120.

Pure water reflux mode: as shown in fig. 4, after the user finishes taking the pure water, the first water taking switch 410 is turned off, and the system enters the pure water reflux mode. When the first water intake switch 410 is closed, the pure water pipeline 400 is pressurized, the pressure detector 430 feeds back a signal to the controller, the first control valve 310 and the pressure booster 320 are kept activated, the second control valve 610 is kept closed, and the third control valve 710 is activated. At this time, the water in the water storage container 100 is pumped by the pressure boosting device 320 to continue to deliver the raw water to the raw water pipeline 300. After the raw water is filtered by the reverse osmosis filter element 200, the obtained concentrated water continuously flows back into the water storage container 100 through the concentrated water pipeline 500; the obtained pure water flows back to the raw water pipeline 300 through the pure water pipeline 400 and the return water pipeline, the pure water is mixed with the raw water on the raw water pipeline 300 to dilute the water before entering the raw water port 210, the concentration of the filtered concentrated water is reduced, and the water concentration (TDS value) on the concentrated water side of the reverse osmosis filter element 200 is further reduced. After the pure water reflux mode is started for a certain time, the first control valve 310, the second control valve 610 and the pressurizing device 320 are closed, and the system stops water production. Therefore, when the water enters a normal water making mode next time, the user takes the first cup of water with a low TDS value.

Automatic drainage mode: when the tap water pipe does not supply water to the water storage container 100 for a long time or the normal water production mode is used for a long time, the water concentration in the water storage container 100 will increase, and the time can be set on the controller. At this time, the second control valve 610 is opened, and the water in the water storage container 100 is automatically discharged through the second branch 600. Or the concentrated water is directly discharged from the second branch 600 during water production and does not flow back into the water storage container 100. Or the controller prompts the user after the set time is reached, and the user can directly open the second water taking switch 810 to discharge the concentrated water.

Self-watering mode: the user can directly turn on the second water intake switch 810 to take the water in the water storage container 100 for use, and the water can be used for washing hands, watering flowers, mopping floor, flushing toilets and other applications which do not have high requirements on water quality.

In some embodiments of the present invention, the second check valve 510 and the waste water valve 520 are disposed on the concentrated water pipeline 500, and the second check valve 510 ensures the concentrated water discharged from the concentrated water inlet 230 to flow in one direction toward the water storage container 100, so as to prevent the concentrated water from flowing back into the reverse osmosis filter element 200. The waste water valve 520 is used for controlling the flow rate of the concentrated water on the concentrated water pipeline 500, and the waste water valve 520 can be a flow valve.

In some embodiments of the present invention, a water quality detecting device 900 is further provided, and the water quality detecting device 900 is used to detect the concentration of the water discharged from the water storage container 100. The water quality detecting device 900 may be installed on the raw water pipeline 300 near the water outlet 120. Or the water quality detecting device 900 is installed in the water storage container 100 and near the water outlet 120. When the water quality detection device 900 detects that the water concentration reaches the preset value, the second control valve 610 is opened, and the prepared concentrated water does not flow back into the water storage container 100 any more, or the water in the water storage container 100 is directly discharged through the second branch 600.

In some embodiments of the present invention, a waterway structure 150 is disposed in the water container 100. The waterway structure 150 may be a partition structure as shown in fig. 1, the water inlet 110 and the water outlet 120 are disposed at the upper portion of the water storage container 100, the water return port 130 is disposed at the lower portion of the water storage container 100, a plurality of partitions distributed up and down are installed inside the water storage container 100, and each partition is staggered left and right in sequence at intervals, so that a long mixing path is formed between the water outlet 120 and the water return port 130. The concentrated water at the lower part of the water storage container 100 can be mixed with the raw water at the upper part only through the mixing path, so that the raw water newly entering the water storage container 100 is discharged from the water outlet 120 for use.
