Description

Technical Field

[0001] This utility model relates to the field of pure water and sparkling water preparation, and in particular to a sparkling water flushing reverse osmosis membrane system for pure water and sparkling water preparation water circuit. 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 bubble water flushing reverse osmosis membrane system that can produce both pure water and sparkling water, and can use the produced sparkling water to flush the reverse osmosis membrane filter element, thereby preventing scaling of the reverse osmosis membrane filter element, ensuring the cleanliness and hygiene of the reverse osmosis membrane filter element, and increasing the service life of the reverse osmosis membrane filter element.

[0004] The technical solution of the bubble water flushing reverse osmosis membrane system for pure water and bubble water preparation circuit 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, and the booster pump is connected to a third water inlet valve and an air outlet connector. The aerated water mixing module has a third inlet valve connected to a reverse osmosis membrane filter element. The reverse osmosis membrane filter element is equipped with a second inlet connector, a pure water connector, and a wastewater connector. The third inlet valve is connected to the second inlet connector. The pure water connector is connected to a post-filter element. The post-filter element is connected to a pure water valve, which is connected to a pure water outlet. The wastewater connector is connected to a wastewater valve, which is connected to a wastewater outlet. The aerated water mixing module is equipped with a third inlet connector and an aerated water connector. The third inlet connector is connected to a booster pump. The aerated water connector is connected to an aerated water valve and a fourth inlet valve. The aerated water valve is connected to an aerated water outlet. The fourth inlet valve is connected to the second inlet connector of the reverse osmosis membrane filter element.

[0005] Furthermore, the outlet of the pre-filter is connected to a first one-way valve and a first pressure sensor.

[0006] Furthermore, a second one-way valve is connected between the air intake valve and the first air intake connector of the air intake and water intake module.

[0007] Furthermore, a third one-way valve and a second pressure sensor are connected between the pure water connector of the reverse osmosis membrane filter element and the post-filter element.

[0008] Furthermore, a bubbler is connected between the bubble water connector and the bubble water valve of the bubble water mixing module.

[0009] The beneficial effects of the bubble water flushing reverse osmosis membrane system of the present invention for the preparation of pure water and bubble water are: 1. It can prepare pure water or bubble water as needed. Pure water is used for drinking water, and bubble water can be used for drinking. In addition, bubble water has a strong cleaning ability and can also be used to clean fruits, vegetables, dishes, etc. with good cleaning effect. Second, the reverse osmosis membrane filter element is rinsed with the prepared bubble water. The bubble water has a strong cleaning ability. When the bubble water is rinsing the reverse osmosis membrane filter element, the bursting of the bubbles has an impact force, which can better clean the reverse osmosis membrane filter element, prevent dirt from accumulating inside the reverse osmosis membrane filter element, and increase the service life of the reverse osmosis membrane filter element.

[0013] This utility model relates to a bubble water flushing reverse osmosis membrane system for pure water and bubble water preparation circuits, such as... Figure 1 — Figure 3 As shown, 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 stabilizing valve 7. The pressure stabilizing 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 stabilizing 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 third water inlet valve 13 and a bubble water mixing module 14. The third water inlet valve 13 is connected to a reverse osmosis membrane filter element 15. The reverse osmosis membrane filter element 15 is provided with a second inlet connector 16, a pure water connector 17, and a wastewater connector 18. The third inlet valve 13 is connected to the second inlet connector 16. The pure water connector 17 is connected to the post-filter element 19. The post-filter element 19 is connected to the pure water valve 20. The pure water valve 20 is connected to the pure water outlet 21. The wastewater connector 18 is connected to the wastewater valve 22. The wastewater valve 22 is connected to the wastewater outlet 23. The aerated water mixing module 14 is provided with a third inlet connector 24 and an aerated water connector 25. The third inlet connector 24 is connected to the booster pump 6.

The fourth inlet valve 27 is connected to the second inlet connector 16 of the reverse osmosis membrane filter element 15.

[0014] Furthermore, the outlet of the pre-filter 3 is connected to a first one-way valve 29 and a first pressure sensor 30. The first one-way valve 29 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 30 can monitor the water pressure of the raw water input to the inlet 1 in real time.

[0015] Furthermore, a second one-way valve 31 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 31 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 32 and a second pressure sensor 33 are connected between the pure water connector 17 of the reverse osmosis membrane filter element 15 and the post-filter element 19. The third check valve 32 can prevent backflow of pure water in the pipeline between the reverse osmosis membrane filter element 15 and the post-filter element 19, and the second pressure sensor 33 can monitor the water pressure of the pure water output by the reverse osmosis membrane filter element 15 in real time.

[0017] Furthermore, an aerator 34 is connected between the aerator 25 and the aerator 26 of the sparkling water mixing module 14. The aerator 34 (the specific structure of the aerator 34 is existing technology and can be directly purchased from the market) can further aerate the sparkling water, making the aerator 34 have a higher aerator 34.

[0018] This utility model discloses a bubble water flushing reverse osmosis membrane system for preparing pure water and bubble water. When people want to obtain pure water (see appendix) Figure 1 Open the first inlet valve 4, the third inlet valve 13, the pure water valve 20, and the wastewater valve 22, and close the second inlet valve 5, the air inlet valve 12, the aerated water valve 26, and the fourth inlet valve 27. The raw water (which can be tap water) is sent to the pre-filter cartridge 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 29 and the first inlet valve 4. The booster pump 6 pressurizes the water after the first filtration and then sends it to the reverse osmosis membrane filter cartridge 15 through the third inlet valve 13 and the second inlet connector 16 for the second filtration. After filtration by the reverse osmosis membrane filter cartridge 15, it is separated into pure water and wastewater. The pure water is sent to the post-filter cartridge 19 through the pure water connector 17 and the third one-way valve 32 for the third filtration. The filtered pure water is output through the pure water valve 20 and the pure water outlet 21, while the wastewater is discharged through the wastewater connector 18 and the wastewater valve 22, and finally discharged from the wastewater outlet 23. When people want to get sparkling water (see appendix) Figure 2Open the second water inlet valve 5, air inlet valve 12, and bubble water valve 26, and close the first water inlet valve 4, third water inlet valve 13, pure water valve 20, wastewater valve 22, and fourth water inlet valve 27. Raw water is transported to the pre-filter element 3 through the water inlet 1 for the first filtration. The water after the first filtration is transported to the pressure regulating valve 7 through the first one-way valve 29 and the second water inlet valve 5. The pressure regulating valve 7 regulates the pressure of the water after the first filtration, and then transports it to the air and water inlet module 8 through the first water inlet connector 9 (the specific structure of the air and water inlet module 8 is existing technology, see patent number 202221629426X, patent name is "integrated bubble water generating mechanism". The air and water inlet module is similar to the jet cavity structure of the patent, and has a shell, a first water inlet connector, a first air inlet connector, a jet cavity, a Venturi jet, a first water outlet connector, etc.). Gas (which can be carbon dioxide or air) is transported through the air inlet 2, air inlet valve 12, second one-way valve 31, and first water outlet connector. The gas is delivered to the air-water inlet module 8 via the gas connector 10. The gas and the water after the first filtration are mixed for the first time in the air-water inlet module 8. The mixture is then delivered to the booster pump 6 via the first water outlet connector 11. The booster pump 6 pressurizes the first gas-water mixture and then delivers it to the bubble water mixing module 14 via the third water inlet connector 24 (the specific structure of the bubble water mixing module 14 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 this 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 14 to obtain fully mixed bubble water. The bubble water is delivered to the bubbler 34 via the bubble water connector 25 for further aeration, and finally output via the bubble water valve 26 and the bubble water outlet 28. When people want to rinse the reverse osmosis membrane filter element 15 with sparkling water (see appendix) Figure 3Open the second water inlet valve 5, air inlet valve 12, fourth water inlet valve 27, and wastewater valve 22, and close the first water inlet valve 4, third water inlet valve 13, pure water valve 20, and aerated water valve 26. Raw water is transported to the pre-filter 3 through inlet 1 for the first filtration. The water after the first filtration is transported to the pressure regulating valve 7 through the first one-way valve 29 and the second water inlet valve 5. The pressure regulating valve 7 regulates the pressure of the water after the first filtration, and then it is transported to the air and water inlet module 8 through the first water inlet connector 9. Gas is transported to the air and water inlet module 8 through the air inlet 2, air inlet valve 12, second one-way valve 31, and first air inlet connector 10. The gas and the water after the first filtration are then transported together. Water undergoes a first gas-liquid mixture in the air-water inlet module 8 and is then transported from the first water outlet connector 11 to the booster pump 6. The booster pump 6 pressurizes the first gas-liquid mixture and then transports it to the bubble water mixing module 14 via the third water inlet connector 24. The first gas-liquid mixture undergoes a second gas-liquid mixture in the bubble water mixing module 14 to obtain fully mixed bubble water. The bubble water is then transported to the reverse osmosis membrane filter element 15 via the fourth water inlet valve 27 and the second water inlet connector 16. The bubble water rinses the reverse osmosis membrane filter element 15 and discharges the dirt in the reverse osmosis membrane filter element 15 through the wastewater connector 18, the wastewater valve 22, and the wastewater outlet 23.
