[0039] Embodiment 1

[0040] like Figure 1 and Figure 2 As shown, the present embodiment provides an initial water production mode of a pure water dilution device, and the water path of the present embodiment is: tap water → pre-filter element 11 → second solenoid valve 6 → booster pump 13 → RO filter element 14 → one-inlet and two-outlet solenoid valve 1 → first TDS probe 4 → first three-way valve 2 → post-filter element 12 → water purification faucet 19 → pure water; in the initial water production mode, the first TDS probe 4 records the TDS value when the system is used for the first time.

[0041] Another water path in this mode is: RO filter element 14 → concentrated water solenoid valve 15 → second three-way valve 16 → waste water, which can discharge the waste water generated in the system.

[0042] Embodiment 2

[0043] like Figure 1 and Figure 3 As shown, this embodiment provides a first water stop mode of a pure water dilution device. The water path of this embodiment is: tap water → pre-filter 11 → second solenoid valve 6 → booster pump 13 → RO filter element 14 → one-inlet and two-outlet solenoid valve 1 → pure water dilution tank 5; wherein when water enters the pure water dilution tank 5, the water is produced to the float position in the tank and stops.

[0044] Another water path in this mode is: RO filter element 14 → concentrated water solenoid valve 15 → second three-way valve 16 → waste water; waste water generated in the system can be discharged.

[0045] Embodiment 3

[0046] like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment provides a re-water production mode of a pure water dilution device. The water path of this embodiment is: tap water → pre-filter element 11 → second solenoid valve 6 → booster pump 13 → RO filter element 14 → one-inlet and two-outlet solenoid valve 1 → pure water dilution tank 5 → second TDS probe 8 → first solenoid valve 10 → first three-way valve 2 → post-filter element 12 → water purification tap 19 → pure water; this mode improves the desalination rate of the equipment through the pure water in the pure water dilution tank 5, dilutes the first cup of water from the filter element used again, thereby reducing the TDS of the first cup of water; another water path is: RO filter element 14 → concentrated water solenoid valve 15 → second three-way valve 16 → waste water (see Figure 4 ) can discharge the waste water generated in the system.

[0047] In addition, when the second TDS probe 8 recognizes that the TDS value of pure water is lower than the TDS value recorded by the first TDS probe 4 in the previous water production, the diaphragm pump 17 is turned on, and the water path of the system is: tap water → pre-filter element 11 → second solenoid valve 6 → booster pump 13 → RO filter element 14 → one-inlet and two-outlet solenoid valve 1 → first TDS probe 4 → first three-way valve 2 → post-filter element 12 → water purification faucet 19 → pure water, the first TDS probe 4 records the TDS value of water when the system is used this time; RO filter element 14 → concentrated water solenoid valve 15 → second three-way valve 16 → waste water, which can discharge the waste water generated in the system; pure water dilution tank 5 → diaphragm pump 17 → second three-way valve 16 → waste water, which can discharge the waste water diluted in the pure water dilution tank 5 to ensure the cleanliness of the pure water in the pure water dilution tank 5 (see Figure 5 ).

[0048] Embodiment 4

[0049] like Figure 1 and Figure 3 As shown, this embodiment provides a water-stopping mode for a pure water dilution device. The water path of this embodiment is: tap water → pre-filter element 11 → second solenoid valve 6 → booster pump 13 → RO filter element 14 → one-inlet and two-outlet solenoid valve 1 → pure water dilution tank 5; wherein, after water enters the pure water dilution tank 5, the water production stops after reaching the float position in the tank. Another water path in this mode is: RO filter element 14 → concentrated water solenoid valve 15 → second three-way valve 16 → waste water, which can discharge the waste water generated in the system. The subsequent water production process repeats the control actions of the water-stopping mode and the water-stopping mode.
