Description

Technical Field

[0001] This utility model relates to the field of pure water and sparkling water preparation, and in particular to a reverse osmosis membrane flushing system for pure water and sparkling water preparation. Background Technology

[0002] As people's living standards continue to improve, they are paying more and more attention to the health of their drinking water, leading to the widespread use of household water purifiers. Water purifiers primarily filter raw water using reverse osmosis membrane filters (RO membrane filters). The filtered pure water enters the pressure tank or is output from the pure water outlet, while most wastewater is discharged through the wastewater outlet. A small amount of wastewater and impurities remain in the reverse osmosis membrane filter. If not cleaned regularly, these impurities will affect the lifespan and filtration efficiency of the reverse osmosis membrane filter. Existing technologies typically involve directly disassembling the reverse osmosis membrane filter for cleaning, which is cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a reverse osmosis membrane flushing system that can produce both pure water and sparkling water, and can flush the reverse osmosis membrane filter element with a large amount of raw water, and can also flush the reverse osmosis membrane filter element when the sparkling water outlet is opened, so as to avoid scaling of the reverse osmosis membrane filter element, ensure the cleanliness and hygiene of the reverse osmosis membrane filter element, and increase the service life of the reverse osmosis membrane filter element.

[0004] The technical solution of the reverse osmosis membrane flushing system for pure water and sparkling water preparation circuits of this utility model is as follows: It includes a water inlet and an air inlet. The water inlet is connected to a pre-filter cartridge, which is connected to a first water inlet valve and a second water inlet valve. The first water inlet valve is connected to a booster pump, and the second water inlet valve is connected to a pressure stabilizing valve. The pressure stabilizing valve is connected to an air and water inlet module. The air and water inlet module is equipped with a first water inlet connector, a first air inlet connector, and a first water outlet connector. The first water inlet connector is connected to the pressure stabilizing valve. The air inlet is connected to an air inlet valve, which is connected to the first air inlet connector of the air and water inlet module. The first water outlet connector is connected to the booster pump. The booster pump is connected to the reverse osmosis membrane filter element. The reverse osmosis membrane filter element is equipped with a second inlet water connector, a pure water connector, and a wastewater connector. The second inlet water connector is connected to the booster pump. The pure water connector is connected to the post-filter element. The post-filter element is connected to the pure water valve. The pure water valve is connected to the pure water outlet. The wastewater connector is connected to the wastewater valve and the aerated water mixing module.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] This utility model relates to a reverse osmosis membrane flushing system for pure water and bubble water preparation circuits, such as... Figure 1 —As shown in the figure, the system includes a water inlet 1 and an air inlet 2. The water inlet 1 is connected to a pre-filter element 3, which is connected to a first water inlet valve 4 and a second water inlet valve 5. The first water inlet valve 4 is connected to a booster pump 6, and the second water inlet valve 5 is connected to a pressure regulating valve 7. The pressure regulating valve 7 is connected to an air and water inlet module 8. The air and water inlet module 8 is equipped with a first water inlet connector 9, a first air inlet connector 10, and a first water outlet connector 11. The first water inlet connector 9 is connected to the pressure regulating valve 7. The air inlet 2 is connected to an air inlet valve 12, which is connected to the first air inlet connector 10 of the air and water inlet module 8. The first water outlet connector 11 is connected to the booster pump 6, which is connected to a reverse osmosis membrane filter element 13. The reverse osmosis membrane filter element 1... The reverse osmosis membrane filter 13 is equipped with a second inlet connector 14, a pure water connector 15, and a wastewater connector 16. The second inlet connector (14) is connected to the booster pump 6. The pure water connector 15 is connected to the post-filter cartridge 17. The post-filter cartridge 17 is connected to the pure water valve 18. The pure water valve 18 is connected to the pure water outlet 19. The wastewater connector 16 is connected to the wastewater valve 20 and the bubble water mixing module 21. The wastewater valve 20 is connected to the wastewater outlet 22. The bubble water mixing module 21 is equipped with a third inlet connector 23 and a bubble water connector 24. The third inlet connector 23 is connected to the wastewater connector 16 of the reverse osmosis membrane filter cartridge 13. The bubble water connector 24 is connected to the bubble water valve 25. The bubble water valve 25 is connected to the bubble water outlet 26.

[0014] Furthermore, the outlet of the pre-filter 3 is connected to a first one-way valve 27 and a first pressure sensor 28. The first one-way valve 27 prevents water in the pipeline between the pressure regulating valve 7 and the pre-filter 3 from flowing back into the pre-filter 3, and the first pressure sensor 28 can monitor the water pressure of the raw water input to the inlet 1 in real time.

[0015] Furthermore, a second one-way valve 29 is connected between the air intake valve 12 and the first air intake connector 10 of the air intake and water intake module 8. The second one-way valve 29 can prevent backflow of gas in the pipeline between the air intake valve 12 and the air intake and water intake module 8.

[0016] Furthermore, a third check valve 30 and a second pressure sensor 31 are connected between the pure water connector 15 of the reverse osmosis membrane filter element 13 and the post-filter element 17. The third check valve 30 can prevent backflow of pure water in the pipeline between the reverse osmosis membrane filter element 13 and the post-filter element 17, and the second pressure sensor 31 can monitor the water pressure of the pure water output by the reverse osmosis membrane filter element 13 in real time.

[0017] Furthermore, an aerator 32 is connected between the aerator 24 and the aerator 25 of the aerator mixing module 21. The aerator 32 (the specific structure of the aerator 32 is existing technology and can be directly purchased from the market) can further aerate the aerator, making the aerator 32 have a higher aerator rate.

[0018] This utility model discloses a reverse osmosis membrane flushing system for preparing pure water and sparkling water. When people want to obtain pure water (see appendix)... Figure 1 Open the first inlet valve 4, pure water valve 18, and wastewater valve 20, and close the second inlet valve 5, air inlet valve 12, and aerated water valve 25. Raw water (which can be tap water) is sent to the pre-filter 3 through the inlet 1 for the first filtration. The water after the first filtration is sent to the booster pump 6 through the first one-way valve 27 and the first inlet valve 4. The booster pump pressurizes the water after the first filtration and then sends it to the reverse osmosis membrane filter 13 through the second inlet connector 14 for the second filtration. After filtration by the reverse osmosis membrane filter 13, it is separated into pure water and wastewater. The pure water is sent to the post-filter 17 through the pure water connector 15 and the third one-way valve 30 for the third filtration. The filtered pure water is output through the pure water valve 18 and the pure water outlet 19, while the wastewater is discharged through the wastewater connector 16 and the wastewater valve 20, and finally discharged from the wastewater outlet 22. When people want to rinse the reverse osmosis membrane filter element 13 with raw water (see appendix) Figure 2 Open the first inlet valve 4 and the wastewater valve 20, and close the second inlet valve 5, the air inlet valve 12, the pure water valve 18, and the aerated water valve 25. The raw water is sent to the pre-filter 3 through the inlet 1 for the first filtration. The water after the first filtration is sent to the booster pump 6 through the first check valve 27 and the first inlet valve 4. The booster pump pressurizes the water after the first filtration and then sends it to the reverse osmosis membrane filter 13 through the second inlet connector 14. Since the pure water valve 18 is closed, the water after the first filtration is directly output from the wastewater connector 16 of the reverse osmosis membrane filter 13. The water after the first filtration is used to rinse the reverse osmosis membrane filter 13 and discharge the dirt in the reverse osmosis membrane filter 13 through the wastewater valve 20 and the wastewater outlet 22. When people want to rinse the reverse osmosis membrane filter element 13 with pre-mixed gas-liquid gas-bubbling water (see appendix) Figure 3Open the second water inlet valve 5, air inlet valve 12, and wastewater valve 20, and close the first water inlet valve 4, pure water valve 18, and aerated water valve 25. Raw water is transported through inlet 1 to pre-filter 3 for the first filtration. The water after the first filtration is transported through the first one-way valve 27 and the second water inlet valve 5 to the pressure regulating valve 7. The pressure regulating valve 7 regulates the pressure of the water after the first filtration, and then it is transported through the first water inlet connector 9 to the air and water inlet module 8 (the specific structure of the air and water inlet module 8 is existing technology, see patent number 202221629426X, patent name "Integrated Aerated Water Generator"). The air and water inlet module is similar to the jet cavity structure of this patent, and has a shell, a first water inlet connector, a first air inlet connector, and a jet cavity. In the structure (such as Venturi jet generator, first water outlet connector, etc.), gas (which can be carbon dioxide or air) is delivered to the air-water inlet module 8 through air inlet 2, air inlet valve 12, second one-way valve 29, and first air inlet connector 10. The gas and the water after the first filtration are mixed for the first time in the air-water inlet module 8 and delivered to the booster pump 6 through the first water outlet connector 11. The booster pump 6 pressurizes the first gas-liquid mixture (i.e., the initially mixed gas-liquid bubble water) and delivers it to the reverse osmosis membrane filter element 13 through the second water inlet connector 14. The initially mixed gas-liquid bubble water rinses the reverse osmosis membrane filter element 13 and discharges the dirt in the reverse osmosis membrane filter element 13 through the wastewater connector, wastewater valve 20, and wastewater outlet 22. When people want to get sparkling water (see appendix) Figure 4Open the second water inlet valve 5, air inlet valve 12, and aerated water valve 25, and close the first water inlet valve 4, pure water valve 18, and wastewater valve 20. Raw water is sent to the pre-filter cartridge 3 through the water inlet 1 for the first filtration. The water after the first filtration is sent to the pressure regulating valve 7 through the first one-way valve 27 and the second water inlet valve 5. The pressure regulating valve 7 regulates the pressure of the water after the first filtration, and then sends it to the air and water inlet module 8 through the first water inlet connector 9. Gas is sent to the air and water inlet module 8 through the air inlet 2, air inlet valve 12, second one-way valve 29, and first air inlet connector 10. The gas and the water after the first filtration are mixed for the first time in the air and water inlet module 8, and then sent to the booster pump 6 through the first water outlet connector 11. The booster pump 6 pressurizes the first gas-liquid mixture and then sends it to the reverse air outlet 14. In the reverse osmosis membrane filter element 13, the first gas-liquid mixture can carry out the dirt in the reverse osmosis membrane filter element 13 and enter the bubble water mixing module 21 through the third water inlet connector 23 (the specific structure of the bubble water mixing module 21 is also existing technology, see patent number 202221629426X, patent name "integrated bubble water generating mechanism", the bubble water mixing module is similar to the gas-liquid mixing chamber structure of the patent, and has a shell, a third water inlet connector, a microporous shearing device, a flow limiting plate, a bubble water connector and other structures). The first gas-liquid mixture undergoes a second gas-liquid mixing in the bubble water mixing module 21 to obtain fully gas-liquid mixed bubble water. The bubble water is transported to the bubbler 32 through the bubble water connector 24 for further foaming, and finally output through the bubble water valve 25 and the bubble water outlet 26.
