However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example 1

[0020] like Figure 1 As shown, the utility model provides a technical solution: a novel reverse osmosis zero stale water micro-discharge water-saving equipment, including a zero stale water ion return waterway 1, a water storage tank concentrated water discharge waterway 2, a tap water inlet and outlet waterway 3 and a RO working waterway 4;

[0022] The RO membrane 11 is connected to a first one-way valve 9 at the front end of the pure water solenoid valve 25, the output end of the first one-way valve 9 is connected to a second one-way valve 10, and the output end of the second one-way valve 10 is connected to a water storage tank 8;

[0023] The output end of the water storage tank 8 is connected to the first PPF 20, the output end of the first PPF 20 is connected to the composite carbon 21, the output end of the composite carbon 21 is connected to the self-priming booster pump 22, the output end of the self-priming booster pump 22 is connected to the discharge solenoid valve 6, and the output end of the discharge solenoid valve 6 is provided with a concentrated water discharge outlet 7;

[0024] The tap water inlet and outlet water path 3 includes a tap water inlet 5, the output end of the tap water inlet 5 is connected to a pressure reducing valve 15 and a second low-pressure switch 17, the output end of the pressure reducing valve 15 is connected to a normally open solenoid valve 14, the output end of the normally open solenoid valve 14 is connected to the input end of the water storage tank 8, the water inlet regulating switch 16 is connected between the pressure reducing valve 15 and the water inlet regulating switch 16, the output end of the water storage tank 8 is connected to the tap water outlet, the water storage tank 8 and the tap water outlet are connected with a fourth one-way valve 18, a first low-pressure switch 13 and a third one-way valve 19, the output end of the water storage tank 8 is connected to The first PPF20, the output end of the first PPF20 is connected to the composite carbon 21, the output end of the composite carbon 21 is connected to the self-priming booster pump 22, the input end of the RO membrane 11 is connected to the second PPF23, the pure water solenoid valve 25 is connected to the pure water TDS probe 12, the output end of the RO membrane 11 is connected to the waste water solenoid valve 24, the output end of the waste water solenoid valve 24 is connected to the input end of the water storage tank 8, the output end of the high pressure switch 27 is connected to the post-carbon 29, the output end of the post-carbon 29 is connected to the pure water faucet 30, and the water storage tank 8 is directly connected to the tap water outlet 31.

[0025] In this embodiment, the RO membrane 11 is connected to the pure water solenoid valve 25 to form a zero-stale water ion return water path 1. 3 minutes before starting up, the pure water solenoid valve 25 is closed, and the stale water exceeding the standard passes through the first one-way valve 9 and the second one-way valve 10 and flows back to the water storage tank 8, completing the zero-stale water return and reconstruction function. The water storage tank 8, the first PPF 20, the composite carbon 21, the self-priming booster pump 22, the discharge solenoid valve 6 and the concentrated water discharge outlet 7 are connected end to end to form the concentrated water discharge water path of the water storage tank 8. When the pure water TDS probe 12 detects that the pure water has reached a certain value, the concentrated water discharge procedure is started, and the discharge is completed and the closing procedure is completed, which is beneficial to increase the service life of R011, ensure that the TDS value of the pure water outlet does not exceed the standard, and ensure that the equipment can continue to work and produce water, and can ensure that the RO membrane 11 is not damaged, and the quality of domestic water is guaranteed. When the tap water inlet and the RO equipment water replenishment water circuit are designed, the pressure difference between the water storage tank 8 and the RO membrane 11 can be effectively controlled to achieve RO equipment circulation water production, while not changing the domestic water use habits and ensuring the domestic water pressure. The water tank 8 is directly connected to the tap water outlet; the water tank 8 is connected to the fourth one-way valve 18, the first low-pressure switch 13, the third one-way valve 19, and the tap water outlet 31, and the first low-pressure switch 13 is linked to the normally open solenoid valve 14. This is the tap water outlet design. In the tap water outlet design, the first low-pressure switch 13 is connected between the fourth one-way valve 18 and the third one-way valve 19. The advantage is that the first low-pressure switch 13 has a stable working state and will not jump at high frequency, which increases the service life of the pressure reducing valve 15 and the normally open solenoid valve 14, making domestic water more stable and improving the user experience. The pure water TDS probe 12 is used to detect the water quality of the pure water outlet of the RO membrane 11. The pure water TDS value setting is the core point of RO equipment control. When the pure water TDS probe 12 and the pure water outlet TDS value in the RO membrane 11 exceed the standard, the equipment starts the concentrated water discharge program, the concentrated water is discharged, and the water production is restored. While ensuring the quality of the water, the purpose of water saving is also achieved. This utility model application adopts a dual water channel design, and the domestic water and RO machine water share a water storage tank. When the water in the water storage tank reaches a certain high concentration, it is discharged to achieve the purpose of water saving. Generally, the ratio of pure wastewater to pure wastewater can reach 3 to 9:1, and the water saving effect is obvious.

[0026] The working principle of this embodiment: when in use, first, when the pure water TDS probe 12 detects that the pure water has reached a certain value, the concentrated water discharge program is started, and the discharge is completed and the closing program is completed, which is beneficial to increase the service life of R011, ensure that the TDS value of the pure water outlet does not exceed the standard, and can ensure that the equipment can continue to work and produce water, and can ensure that the RO membrane 11 is not damaged, and the water quality of domestic water is guaranteed. When the tap water inlet and the RO equipment water replenishment water circuit are designed, the pressure difference between the water storage tank 8 and the RO membrane 11 can be effectively controlled to achieve RO equipment circulation water production, while not changing the domestic water use habits and ensuring the domestic water pressure. The water tank 8 is directly connected to the tap water outlet 31, and the water tank 8 is connected to the fourth one-way valve 18, the first low-pressure switch 13, the third one-way valve 19, and the tap water outlet 31. The first low-pressure switch 13 is linked to the normally open solenoid valve 14. This is the tap water outlet design. In the tap water outlet design, the first low-pressure switch 13 is connected between the fourth one-way valve 18 and the third one-way valve 19. The advantage is that the working state of the first low-pressure switch 13 is stable and will not jump at high frequency, which increases the service life of the pressure reducing valve 15 and the normally open solenoid valve 14. When the pure water TDS probe 12 and the pure water outlet TDS value in the RO membrane 11 exceed the standard, the equipment starts the concentrated water discharge program, the concentrated water is discharged, and water production is restored. While ensuring the quality of the water, the purpose of water saving is also achieved. This utility model application adopts a dual water channel design, and the domestic water and RO machine water share a water storage tank. When the water in the water storage tank reaches a certain high concentration, it is discharged to achieve the purpose of water saving. Generally, the ratio of pure wastewater to pure wastewater can reach 3 to 9:1, and the water saving effect is obvious.
