Description

Technical Field

[0001] This utility model relates to the field of sparkling water and pure water preparation, and in particular to a stable sparkling water and pure water preparation system. 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 through a reverse osmosis membrane. Pure water is output through the pure water outlet of the reverse osmosis membrane filter element (RO membrane filter element), while wastewater is discharged directly through the wastewater outlet. Traditional water purifiers typically only purify and filter water, offering relatively simple functions. For example, ordinary water purifiers cannot provide sparkling water. Therefore, people invented water purifiers that can produce sparkling water and pure water. However, existing water purifiers usually directly input raw water from the inlet and carbon dioxide gas from the air inlet when producing sparkling water or pure water. The raw water and carbon dioxide are mixed through the sparkling water air intake module and the sparkling water mixing module to form sparkling water. Finally, the sparkling water is output from the sparkling water outlet. The disadvantage of this structure is that the raw water is usually the tap water in the household, and the water pressure of the raw water may be unstable. If the raw water pressure is low, it will cause the water to vibrate, resulting in a low bubble rate when the raw water and carbon dioxide are mixed, and the bubbles will easily disappear, resulting in poor sparkling water effect. When the raw water supply is interrupted, it will be impossible to produce pure water and sparkling water. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a stable sparkling water and pure water preparation system that makes the raw water pressure more stable, ensures the effect of sparkling water, and can continue to supply a certain amount of water even when the water supply is interrupted.

[0004] The technical solution of this utility model for a stable sparkling water and pure water preparation system is as follows: It includes a water inlet and an air inlet. The water inlet is connected to a pre-filter, which is connected to a first water inlet valve. The first water inlet valve is connected to the first interface of a four-way connector. The second interface of the four-way connector is connected to a second water inlet valve, which is connected to a booster pump. The third interface of the four-way connector is connected to a pressure stabilizing valve, which 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, which is connected to the first... The three-inlet valve and the sparkling water mixing module are configured as follows: the third inlet valve is connected to the 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 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; the wastewater valve is connected to the wastewater outlet; the sparkling water mixing module is equipped with a third inlet connector and a sparkling water connector; the third inlet connector is connected to the booster pump; the sparkling water connector is connected to the sparkling water valve and the pressure storage tank; the sparkling water valve is connected to the sparkling water outlet; the pressure storage tank is connected to a fourth inlet valve; and the fourth inlet valve is connected to the fourth port of the four-way connector.

[0005] 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.

[0006] 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.

[0007] Furthermore, a bubbler is connected between the bubble water connector and the bubble water valve of the bubble water mixing module.

[0008] Furthermore, a fourth one-way valve is connected between the bubble water connector of the bubble water mixing module and the pressure storage tank.

[0009] Furthermore, a third pressure sensor is connected between the pressure storage tank and the fourth inlet valve.

[0010] Furthermore, a fifth check valve is connected between the fourth inlet valve and the fourth port of the four-way connector.

[0011] The beneficial effects of this utility model of a stable sparkling water and pure water preparation system are: First, it can prepare pure water or sparkling water as needed. Pure water is used for drinking water, and sparkling water can be used for drinking. In addition, sparkling water has a strong cleaning ability and can also be used to clean fruits, vegetables, dishes, etc., with good cleaning effect. Second, a certain amount of water can be stored in the pressure storage tank. When preparing sparkling water or pure water, and the raw water pressure is insufficient or unstable, the pressure storage tank can be used as a water source and water can be output simultaneously with the inlet to make the raw water pressure more stable, reduce the water output shaking caused by unstable water pressure, and make the prepared sparkling water have a good bubble effect. Third, in the event of a water outage, the pressure storage tank can be used directly as a water source, and a certain amount of water can continue to be supplied to prepare sparkling water and pure water.

[0018] Furthermore, the outlet of the pre-filter 3 is connected to a first one-way valve 35 and a first pressure sensor 36. The first one-way valve 35 prevents water in the pipeline between the first inlet valve 4 and the pre-filter 3 from flowing back into the pre-filter 3, and the first pressure sensor 36 can monitor the water pressure of the raw water entering through the inlet 1 in real time.

[0025] This utility model discloses a stable sparkling water and pure water preparation system, which is used when people want to prepare sparkling water (see appendix). Figure 1The first inlet valve 4, air inlet valve 16, and aerated water valve 30 are opened, while the second inlet valve 8, third inlet valve 17, pure water valve 24, wastewater valve 26, and fourth inlet valve 33 are closed. Raw water (which can be tap water) is transported through inlet 1 to the pre-filter cartridge 3 for the first filtration. The water after the first filtration is transported through the first one-way valve 35, the first inlet valve 4, and the first port 6 and the third port 10 of the four-way connector 5 to the pressure regulating valve 11. The pressure regulating valve 11 regulates the water after the first filtration. The pressure is stabilized, and then the gas is delivered to the air and water inlet module 12 via the first water inlet connector 13 (the specific structure of the air and water inlet module 12 is existing technology, see patent number 202221629426X, patent name "Integrated Bubble 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, a jet cavity, a Venturi jetter, a first water outlet connector, etc. The gas (which can be carbon dioxide or air) is introduced through the air inlet connector. The gas is fed into the air-water inlet module 12 via the inlet 2, air inlet valve 16, second one-way valve 37, and first air inlet connector 14. The gas and the water after the first filtration are mixed for the first time in the air-water inlet module 12 and then fed into the booster pump 9 via the first water outlet connector 15. The booster pump 9 pressurizes the first gas-liquid mixture and then feeds it into the bubble water mixing module 18 (the specific structure of the bubble water mixing module 18 is also existing technology, see patent number 202221629426X, patent name is "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 is mixed for the second time in the bubble water mixing module 18 to obtain fully mixed bubble water. The bubble water is fed into the bubble water connector 29 to the bubbler 40 for further aeration and finally output through the bubble water valve 30 and the bubble water outlet 32. When people want to prepare pure water (see appendix) Figure 2 Open the first inlet valve 4, the second inlet valve 8, the third inlet valve 17, the pure water valve 24, and the wastewater valve 26, and close the air inlet valve 16, the aerated water valve 30, and the fourth inlet valve 33. The raw water is sent to the pre-filter cartridge 3 for the first filtration through the inlet 1. The water after the first filtration is sent to the booster pump 9 through the first one-way valve 35, the first inlet valve 4, the first interface 6 and the second interface 7 of the four-way connector 5, and the second inlet valve 8. The booster pump 9 pressurizes the water after the first filtration and then sends it to the reverse osmosis membrane filter cartridge 19 for the second filtration through the third inlet valve 17 and the second inlet connector 20. After filtration by the reverse osmosis membrane filter cartridge 19, the water is separated into pure water and wastewater. The pure water is sent to the post-filter cartridge 23 for the third filtration through the pure water connector 21. The filtered pure water is output through the pure water valve 24 and the pure water outlet 25, while the wastewater is discharged through the wastewater connector 22 and the wastewater valve 26, and finally discharged from the wastewater outlet 27. When it is necessary to store water in pressure storage tank 31 (see appendix) Figure 3 Open the first water inlet valve 4, and close the second water inlet valve 8, air inlet valve 16, third water inlet valve 17, pure water valve 24, wastewater valve 26, aerated water valve 30, and fourth water inlet valve 33. The raw water is transported to the pre-filter 3 through the water inlet 1 for the first filtration. The water after the first filtration is transported to the pressure stabilizing valve 11 through the first one-way valve 35, the first water inlet valve 4, the first interface 6 and the third interface 10 of the four-way connector 5. The pressure stabilizing valve 11 stabilizes the pressure of the water after the first filtration, and then it is transported to the air and water inlet module 12 through the first water inlet connector 13. Then it is output to the booster pump 9 for pressurization through the first water outlet connector 15, and then transported to the pressure storage tank 31 (the specific structure of the pressure storage tank is existing technology) through the aerated water mixing module 18 and the fourth one-way valve 41 for storage. When preparing sparkling water, if the raw water pressure is unstable or insufficient (see appendix) Figure 4 Open the first inlet valve 4, air inlet valve 16, aerated water valve 30, and fourth inlet valve 33, and close the second inlet valve 8, third inlet valve 17, pure water valve 24, and wastewater valve 26. Raw water and pressure storage tank 31 simultaneously begin supplying water. Raw water is transported through inlet 1 to pre-filter 3 for the first filtration. The filtered water is then transported through the first one-way valve 35, the first inlet valve 4, and the first port 6 and third port 10 of the four-way connector 5 to the pressure regulating valve 11. Water stored in the pressure storage tank 31 (the specific structure of the pressure storage tank is based on existing technology, which can output a stable pressure water source) is transported through the fourth inlet valve 33, the fifth one-way valve 43, and the fourth port 34 and third port 10 of the four-way connector 5 to the pressure regulating valve 11. The pressure regulating valve 11 then regulates the water supplied from inlet 1 and pressure storage tank 31. The pressure is stabilized, and then the gas is delivered to the air and water inlet module 12 via the first water inlet connector 13. The gas is delivered to the air and water inlet module 12 via the air inlet 2, air inlet valve 16, second one-way valve 37, and first air inlet connector 14. The gas and the water after the first filtration are mixed for the first time in the air and water inlet module 12, and then delivered to the booster pump 9 via the first water outlet connector 15. The booster pump 9 pressurizes the first gas-liquid mixture and then delivers it to the bubble water mixing module 18. The first gas-liquid mixture is mixed for the second time in the bubble water mixing module 18 to obtain fully mixed bubble water. The bubble water is delivered to the bubbler 40 via the bubble water connector 29 for further aeration, and finally output via the bubble water valve 30 and bubble water outlet 32. If the raw water supply is interrupted, the first water inlet valve 4 is closed, and the water is supplied entirely by the pressure storage tank. When preparing pure water, if the raw water pressure is unstable or insufficient (see appendix) Figure 5Open the first inlet valve 4, the second inlet valve 8, the third inlet valve 17, the pure water valve 24, the wastewater valve 26, and the fourth inlet valve 33; close the air inlet valve 16 and the aerated water valve 30. The raw water and the pressure storage tank 31 begin supplying water simultaneously. The raw water is transported through inlet 1 to the pre-filter 3 for the first filtration. The filtered water is then transported through the first one-way valve 35, the first inlet valve 4, the first port 6 and the second port 7 of the four-way connector 5, and the second inlet valve 8 to the booster pump 9. The water stored in the pressure storage tank 31 is transported through the fourth inlet valve 33, the fifth one-way valve 43, the fourth port 34 and the second port 7 of the four-way connector 5. The second inlet valve 8 delivers water to the booster pump 9, which pressurizes the water from the inlet 1 and the pressure storage tank 31. The water is then delivered to the reverse osmosis membrane filter 19 via the third inlet valve 17 and the second inlet connector 20. After filtration by the reverse osmosis membrane filter 19, the water is separated into pure water and wastewater. The pure water is then delivered to the post-filter 23 via the pure water connector 21 for a third filtration. The filtered pure water is then output via the pure water valve 24 and the pure water outlet 25, while the wastewater is discharged via the wastewater connector 22 and the wastewater valve 26, and finally discharged from the wastewater outlet 27. If the raw water supply is interrupted, the first inlet valve 4 is closed, and the water is supplied entirely by the pressure storage tank.
