It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

The terms "first", "second" and the like are only used for descriptive purposes and do not represent any order, quantity or importance, but are only used to distinguish different components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific circumstances.

[0040] Figure 1 A schematic diagram of the structure of a water purification system provided by an embodiment of the utility model is shown as follows: Figure 1 As shown, the water purification system includes: an inlet pipeline 10, a purified water pipeline 20, an air inlet pipeline 30 and a reverse osmosis membrane filter assembly 40; the first end of the inlet pipeline 10 is connected to the raw water inlet A, and the second end of the inlet pipeline 10 is connected to the first water inlet 40a of the reverse osmosis membrane filter assembly 40; the inlet pipeline 10 includes an inlet solenoid valve 103 and a micro bubble water generating assembly 101, and the inlet solenoid valve 103 and the micro bubble water generating assembly 101 are sequentially arranged at the raw water inlet A and the reverse osmosis membrane filter assembly Between the components 40, the microbubble water generating component 101 is used to generate microbubble water; the first end of the clean water pipeline 20 is connected to the first water outlet 40b of the reverse osmosis membrane filtration component 40, and the second end of the clean water pipeline 20 is connected to the water outlet faucet B; the clean water pipeline 20 includes a clean water solenoid valve 202, and the clean water solenoid valve 202 is used to control the on-off of the water inlet pipeline 10 and the clean water pipeline 20; the air inlet end of the air inlet pipeline 30 is connected to the air pump 301, and the air outlet end of the air inlet pipeline 30 is connected to the water inlet pipeline 10.

[0041] Specifically, Figure 1 As shown, the raw water inlet A is the tap water inlet, the water inlet pipeline 10 is the water inlet path of the raw water, and the water inlet solenoid valve 103 is used to control the flow state of the raw water in the water inlet pipeline 10. When the water inlet solenoid valve 103 is turned on, the unfiltered raw water flows through the water inlet pipeline 10 to the first water inlet 40a of the reverse osmosis membrane filter assembly 40; when the water inlet solenoid valve 103 is closed, the unfiltered raw water cannot flow to the first water inlet 40a of the reverse osmosis membrane filter assembly 40. In the normal pure water intake mode, the raw water flows from the first water outlet 40b of the reverse osmosis membrane filter assembly 40 to the clean water pipeline 20 after being filtered by the reverse osmosis membrane filter assembly 40. After the user turns on the water outlet faucet B, the pure water flows out from the water outlet faucet B.

[0042] Continue to refer Figure 1 The microbubble water generating assembly 101 is installed in the area of ​​the water inlet pipeline 10 near the reverse osmosis membrane filter assembly 40. The air inlet end of the air inlet pipeline 30 is connected to the air pump 301, and the air outlet end is connected to the water inlet pipeline 10, and the air outlet end is arranged upstream of the microbubble water generating assembly 101. After the air pump 301 is turned on, the air pump 301 can transport external air to the water inlet pipeline 10, and the gas and the raw water in the water inlet pipeline 10 become microbubble water after passing through the microbubble water generating assembly 101.

[0043] The size of the bubbles inside the microbubble water is generally between 1 and 100 microns. Since the microbubble water is filled with a large number of tiny bubbles, it appears milky white in visual effect. Microbubble water has a strong decontamination ability and is widely used in the fields of skin cleaning, fruit and vegetable washing, and sewage treatment. Based on the above advantages of microbubble water, this embodiment proposes that microbubble water can be used to clean the reverse osmosis membrane of the reverse osmosis membrane filter assembly 40.

[0044] In this embodiment, the water purification system may include a cleaning mode. In the cleaning mode, the air pump 301 can be controlled to open, the water inlet solenoid valve 103 can be controlled to open, and the water purification solenoid valve 202 can be closed, and the microbubble water generating component 101 can be controlled to work, and the microbubble water generating component 101 is used to generate microbubble water. The microbubble water flows to the reverse osmosis membrane filter component 40 through the first water inlet 40a, and the dirt deposited on the surface of the reverse osmosis membrane is cleaned by the microbubble water. In this way, the cleaning of the reverse osmosis membrane can be achieved without the need to add an additional cleaning pipeline. While ensuring the cleaning effect of the reverse osmosis membrane, the cleaning efficiency is improved, thereby extending the service life of the reverse osmosis membrane and ensuring that the filtered pure water has a better taste.

[0045] In an embodiment of the utility model, a water purification system comprises: a water inlet pipeline, a clean water pipeline, an air inlet pipeline and a reverse osmosis membrane filter assembly; the first end of the water inlet pipeline is connected to the raw water inlet, and the second end of the water inlet pipeline is connected to the first water inlet of the reverse osmosis membrane filter assembly; the water inlet pipeline comprises a water inlet solenoid valve and a micro-bubble water generating assembly, the water inlet solenoid valve and the micro-bubble water generating assembly are sequentially arranged between the raw water inlet and the reverse osmosis membrane filter assembly, and the micro-bubble water generating assembly is used to generate micro-bubble water; the first end of the clean water pipeline is connected to the first water outlet of the reverse osmosis membrane filter assembly, and the second end of the clean water pipeline is connected to the water outlet faucet; the clean water pipeline comprises a water purification solenoid valve, and the water purification solenoid valve is used to control the on-off of the water inlet pipeline and the clean water pipeline; the air inlet end of the air inlet pipeline is connected to the air pump, and the air outlet end of the air inlet pipeline is connected to the water inlet pipeline. With the above solution, in the cleaning mode, microbubble water can be introduced into the reverse osmosis membrane filter assembly, and the reverse osmosis membrane surface can be cleaned with microbubble water to ensure the cleanliness of the reverse osmosis membrane and improve the service life and filtering effect of the reverse osmosis membrane filter assembly. In addition, the above solution does not require the additional setting of cleaning pipelines, and does not require the addition of detergents to clean the reverse osmosis membrane, which can simplify the structure of the water purification system and the cleaning process of the reverse osmosis membrane and improve the cleaning efficiency.

[0046] Optional, you can continue to refer to Figure 1 In some embodiments, the water purification system also includes a concentrate water pipeline 50, a first end of the concentrate water pipeline 50 is connected to the second water outlet 40c of the reverse osmosis membrane filtration assembly 40, a second end of the concentrate water pipeline 50 is connected to the concentrate water outlet C, and the concentrate water pipeline 50 includes a concentrate water solenoid valve 501, which is used to control the on-off of the concentrate water pipeline 50 and the water inlet pipeline 10.

[0047] Specifically, in the pure water intake mode, the raw water is filtered into pure water with less impurities and concentrated water with more impurities after passing through the reverse osmosis membrane filter assembly 40. The second water outlet 40c of the reverse osmosis membrane filter assembly 40 is connected to the concentrated water pipeline 50. When the concentrated water solenoid valve 501 is opened, the concentrated water can be discharged through the concentrated water pipeline 50.

[0048] In this embodiment, the cleaning mode may include a direct flushing procedure. When the direct flushing procedure is executed, the air pump 301, the water inlet solenoid valve 103 and the concentrated water solenoid valve 501 are controlled to be turned on, and the water purification solenoid valve 202 is closed. Since the concentrated water solenoid valve 501 is turned on, the second water outlet 40c of the reverse osmosis membrane filtration assembly 40 is connected to the concentrated water pipeline 50, and the microbubble water after cleaning the reverse osmosis membrane can flow into the concentrated water pipeline 50 and finally be discharged from the concentrated water outlet C. In this way, after the direct flushing procedure is executed, the reverse osmosis membrane is cleaned, and no sewage remains in the water purification system pipeline.

[0049] Optionally, a concentrate water outlet valve 502 may be provided in the concentrate water pipeline 50. The concentrate water outlet valve 502 may be installed between the concentrate water solenoid valve 501 and the concentrate water outlet C. The concentrate water outlet valve 502 is used to adjust the outlet water flow rate.

[0050] Optional, you can continue to refer to Figure 1 The water purification system also includes a return pipe 60, a first end of the return pipe 60 is connected to the second water outlet 40c of the reverse osmosis membrane filtration component 40, a second end of the return pipe 60 is connected to the water inlet pipe 10, and the second end of the return pipe 60 is connected to the upstream pipe of the micro bubble water generating component 101; the return pipe 60 includes a return solenoid valve 601 and a first one-way valve 602, the return solenoid valve 601 is used to control the connection and disconnection of the return pipe 60 and the water inlet pipe 10, the inlet of the first one-way valve 602 is close to the first end of the return pipe 60, and the outlet of the first one-way valve 602 is close to the second end of the return pipe 60.

[0051] Specifically, Figure 1 As shown, the first end of the return line 60 can be connected to the portion of the concentrated water line 50 between the second water outlet 40c of the reverse osmosis membrane filtration assembly 40 and the concentrated water solenoid valve 501, and the second end of the return line 60 can be connected to the downstream line of the water inlet solenoid valve 103 in the water inlet line 10. The return solenoid valve 601 and the first one-way valve 602 can be installed in sequence between the first end and the second end of the return line 60. When the return solenoid valve 601 is turned on, the water path between the return line 60 and the water inlet line 10 is connected, and when the return solenoid valve 601 is closed, the water path between the return line 60 and the water inlet line 10 is disconnected. The first one-way valve 602 is used to control the water flow direction in the return line 60 to always be the direction from the first end of the return line 60 to the second end.

[0052] In this embodiment, the cleaning mode may include a direct flushing program and a circulating flushing program. The execution order of the direct flushing program and the circulating flushing program is not limited, and those skilled in the art can set it according to actual conditions. When executing the circulating flushing program, the reflux solenoid valve 601 is controlled to be turned on, the water purification solenoid valve 202 is closed, the concentrated water solenoid valve 501 is closed, and the micro bubble water generating component 101 is working. At the same time, the air pump 301 can be controlled to be turned on or off. If the circulating flushing program is executed after the direct flushing program, since there is already gas in the pipeline during the direct flushing program, the air pump 301 can be controlled to be turned off during the circulating flushing program, which has an energy-saving effect; if the circulating flushing program is executed before the direct flushing program, the air pump 301 can be controlled to be turned on during the circulating flushing program to ensure that there is gas in the pipeline.

[0053] In this way, under the circulating flushing procedure, the microbubble water circulates between the water inlet pipe 10, the reverse osmosis membrane filter assembly 40, part of the concentrated water pipe 50, the connection node between the concentrated water pipe 50 and the return pipe 60, and the return pipe 60, and the microbubble water circulates to flush the reverse osmosis membrane, continuously flushing away the dirt on the surface of the reverse osmosis membrane, thereby improving the cleaning effect of the reverse osmosis membrane.

[0054] Optionally, the cleaning mode also includes a drainage procedure, which is executed after the circulating flushing procedure; in the drainage procedure, the concentrated water solenoid valve 501 is controlled to be opened, and the reflux solenoid valve 601 is controlled to be closed, and the microbubble water for circulating flushing the reverse osmosis membrane is discharged through the concentrated water outlet C.

[0055] Further, in an exemplary embodiment, the direct flushing procedure may be performed first and then the circulating flushing procedure may be performed. In this setting mode, the cleaning mode includes the direct flushing procedure, the circulating flushing procedure and the draining procedure. After the circulating flushing procedure is performed, the water inlet solenoid valve 103 and the concentrated water solenoid valve 501 are controlled to be opened, the clean water solenoid valve 202 and the reflux solenoid valve 601 are closed, the microbubble water generating assembly 101 stops working, and the washed sewage is discharged from the concentrated water outlet C.

[0056] Of course, in some other embodiments, the circulating flushing mode may be executed first and then the direct flushing procedure. Since the wastewater used to clean the reverse osmosis membrane is directly discharged in the direct flushing procedure, the drainage procedure may no longer be set. The cleaning mode consists of the circulating flushing procedure and the direct flushing procedure.

[0057] Optional, you can continue to refer to Figure 1 The concentrated water pipeline also includes a water quality detection device 503; the water quality detection device 503 and the concentrated water solenoid valve 501 are sequentially arranged in the communication path between the first end and the second end of the concentrated water pipeline 50; the water quality detection device 503 is used to detect impurity parameters in water.

[0058] like Figure 1As shown, the water quality detection device 503 can be arranged in the concentrated water pipeline 50 between the second water outlet 40c of the reverse osmosis membrane filter assembly 40 and the reflux pipeline 60. The water quality detection device 503 can detect the impurity content in the water (microbubble water or concentrated water) flowing through it and generate an impurity parameter. It is understandable that when the water purification system is used in the pure water intake mode, if the impurity parameter detected by the water quality detection device 503 is large (for example, exceeding the impurity parameter threshold), it means that the impurity content in the concentrated water exceeds the normal range. At this time, it can be judged that the reverse osmosis membrane surface is seriously blocked and the reverse osmosis membrane needs to be cleaned, thereby controlling the water purification system to enter the cleaning mode.

[0059] In this embodiment, the impurity parameters detected by the water quality detection device 503 are used as the basis for judging whether to enter the cleaning mode. The reverse osmosis membrane cleaning work is matched with the actual use status of the reverse osmosis membrane, and intelligent automatic cleaning of the water purification system can be achieved.

[0060] Optionally, the specific type of the water quality detection device 503 is not limited, for example, it can be a total organic carbon (TOC) sensor, a chemical oxygen demand (COD) sensor, a turbidity sensor or a conductivity probe, but is not limited to this. Any device that can detect the impurity content in water is within the scope of the technical solution protected by the embodiment of the utility model.

[0061] Optionally, the water purification system also includes a controllable board (not shown in the figure), which is electrically connected to the water inlet solenoid valve 103, the microbubble water generating assembly 101, the concentrated water solenoid valve 501, the reflux solenoid valve 601 and the water quality detection device 503 respectively.

[0062] The control panel is the main control panel of the water purification system. All the electronic control components in the water purification system can be controlled by the control panel. The opening and closing of the above components and the judgment of the cleaning mode are all completed by the control panel.

[0063] Optionally, the control panel may also be electrically connected to the concentrated water outlet valve 502 to control the drainage rate through the concentrated water outlet valve 502 .

[0064] Optional, Figure 2 A schematic diagram of the structure of another water purification system provided by an embodiment of the utility model, Figure 3 This is a schematic diagram of the structure of another water purification system provided by the embodiment of the utility model. Figure 1 , the outlet end of the air inlet pipe 30 is directly connected to the water inlet pipe 10; or, refer to Figure 2 , the outlet end of the air inlet pipeline 30 is connected to the return pipeline 60, and is connected to the water inlet pipeline 10 through the return pipeline 60; or, refer to Figure 3The air outlet end of the air intake pipeline 30 is connected to the concentrated water pipeline 50, and is connected to the water intake pipeline 10 through the concentrated water pipeline 50 and the return pipeline 60; a second one-way valve 302 is provided in the air intake pipeline 30, the inlet of the second one-way valve 302 is close to the air pump 301, and the outlet of the second one-way valve 302 is close to the air outlet end of the air intake pipeline 30.

[0065] Specifically, in Figure 1 In the embodiment shown, the air outlet end of the air inlet pipeline 30 is directly connected to the water inlet pipeline 10; Figure 2 In the illustrated embodiment, the air outlet end of the air inlet pipeline 30 is connected to the return pipeline 60, and then connected to the water inlet pipeline 10 through the return pipeline 60; Figure 2 In the illustrated embodiment, the air outlet end of the air inlet pipeline 30 is connected to the concentrated water pipeline 50 , and further connected to the water inlet pipeline 10 through the concentrated water pipeline 50 and the return pipeline 60 .

[0066] Among them, a second one-way valve 302 can be set in the air intake pipeline 30, the inlet of the second one-way valve 302 is close to the air pump 301, and the outlet is close to the air outlet end. The second one-way valve 302 is used to prevent the water flow in the water inlet pipeline 10, the return pipeline 60 or the concentrated water pipeline 50 from flowing back to the air intake pipeline 30.

[0067] Optional, you can continue to refer to Figure 1 The water inlet pipeline 10 also includes a first filter element 102, an air dissolving tank 104 and a booster pump 105; the first filter element 402 is located between the raw water inlet A and the water inlet solenoid valve 103, and the air dissolving tank 104 and the booster pump 105 are arranged between the water inlet solenoid valve 103 and the micro-bubble water generating component 101; the clean water pipeline 20 also includes a second filter element 201, and the second filter element 201 and the clean water solenoid valve 202 are sequentially arranged in the connecting path between the first end and the second end of the clean water pipeline 20.

The first filter element 102 is a pre-treatment filter element, which is used to perform coarse filtration on the raw water. The air dissolving tank 104 is used to mix the gas and water in the water inlet pipeline 10 so that the gas and water are mixed evenly, and prevent the gas from entering the booster pump 105 and causing the booster pump 105 to be blocked. The booster pump 105 is connected to the control panel, and the booster pump 105 is used to pressurize the water. Among them, the air outlet end of the air inlet pipeline 30 and the second end of the return pipeline 60 can be connected to the water inlet pipeline 10 between the water inlet solenoid valve 103 and the air dissolving tank 104.

[0069] Of course, the arrangement positions of the components in the water inlet pipeline 10 are only examples. In actual application, the positions of the components can be adjusted according to actual needs.

[0070] like Figure 1 As shown, the second filter element 201 and the water purification solenoid valve 202 can be arranged in sequence between the reverse osmosis membrane filter assembly 40 and the water outlet faucet B. The second filter element 201 is a post-processing filter element, which is used to filter the pure water entering the water purification system again to improve the taste of the pure water.

[0071] When the water purification system is in the pure water intake mode, the control panel can control the water inlet solenoid valve 103, the booster pump 105, the foaming solenoid valve 1011, the water purification solenoid valve 202, the concentrated water solenoid valve 501 and the concentrated water outlet valve 502 to open, the reflux solenoid valve 601 and the air pump 301 to close, and adjust the flow control valve 1061 to the maximum opening. The raw water is filtered by the reverse osmosis membrane filter assembly 40 to become pure water and concentrated water. The pure water flows to the water purification pipeline 20 through the first water outlet 40b. When the user turns on the water outlet faucet B, the pure water flows out from the water outlet faucet B; the concentrated water flows to the concentrated water pipeline 50 through the second water outlet 40c, and is finally discharged to the sewer from the concentrated water outlet C.

[0072] In the direct flushing procedure of the cleaning mode, the control panel can specifically control the water inlet solenoid valve 103, the air pump 301, the booster pump 105, the concentrated water solenoid valve 501 and the concentrated water outlet valve 502 to be opened, the clean water solenoid valve 202 and the reflux solenoid valve 601 to be closed, and the microbubble water generating component 101 to work. In the circulating flushing procedure of the cleaning mode, the control panel can specifically control the booster pump 105 and the reflux solenoid valve 601 to be opened, the water inlet solenoid valve 103, the clean water solenoid valve 202, the air pump 301, the concentrated water solenoid valve 501 and the concentrated water outlet valve 502 to be closed, and the microbubble water generating component 101 to work. In the drainage procedure of the cleaning mode, the control panel can specifically control the water inlet solenoid valve 103, the booster pump 105, the concentrated water solenoid valve 501 and the concentrated water outlet valve 502 to be opened, the air pump 301, the clean water solenoid valve 202 and the reflux solenoid valve 601 to be closed, and the microbubble water generating component 101 to stop working.

[0073] Optional, you can continue to refer to Figure 1 The water inlet pipeline 10 may also include a water-gas ratio regulating mechanism 106 and a pressure detection component 107, and the water-gas ratio regulating mechanism 106 and the pressure detection component 107 are sequentially arranged in the communication path between the raw water inlet A and the dissolved gas tank 104.

[0074] Specifically, the water-gas ratio adjustment mechanism 106 can be installed between the first filter element 102 and the water inlet solenoid valve 103, and the water-gas ratio adjustment mechanism 106 is used to control the distribution ratio of water and gas in the downstream water inlet pipeline 10. Optionally, the pressure detection component 107 is arranged between the water inlet solenoid valve 103 and the gas dissolving tank 104, and the pressure detection component 107 is used to detect the pressure before the pump, that is, the water pressure in the water inlet pipeline 10 downstream of the water-gas ratio adjustment mechanism 106. The pressure detection component 107 can be a pressure gauge, but is not limited thereto.

[0075] Exemplarily, the water-gas ratio regulating mechanism 106 may include a flow control valve 1061 and a pressure reducing valve 1062, and the flow control valve 1061 and the pressure reducing valve 1062 are arranged in parallel. The flow control valve 1061 is electrically connected to the control board, and the flow control valve 1061 may be a stepping motor, but is not limited thereto. The control board may adjust the distribution ratio of the inlet water in the parallel pipeline by changing the opening of the flow control valve 1061. The larger the opening of the flow control valve 1061, the larger the water flow flowing to the water inlet solenoid valve 103 through the flow control valve 1061; the smaller the opening of the flow control valve 1061, the smaller the water flow flowing to the water inlet solenoid valve 103 through the flow control valve 1061. The larger the water flow flowing to the water inlet solenoid valve 103 through the flow control valve 1061, the greater the pressure in the water inlet pipeline 10 upstream of the gas dissolving tank 104, and the gas is less likely to enter the water inlet pipeline 10, and vice versa, the gas is more likely to enter the water inlet pipeline 10.

[0076] Based on the above structure, when the water purification system is in the direct flushing program, the control panel can adjust the flow control valve 1061 to a preset opening range. Within the preset opening range, the water flow through the flow control valve 1061 is moderate, so that the pressure in the downstream water inlet pipeline 10 is moderate, ensuring that the gas can enter the water inlet pipeline 10. When the water purification system is in the circulation flushing program, the control panel can control the flow control valve 1061 to close. When the water purification system is in the drainage program, the control panel can adjust the flow control valve 1061 to the maximum opening, so that the raw water has a large pressure to flow to the downstream pipeline, ensuring the sewage discharge effect.

[0077] Optional, you can continue to refer to Figure 1 The micro-bubble water generating component 101 includes a bubble solenoid valve 1011, and the bubble solenoid valve 1011 includes an open state and a closed state. In the open state, the raw water remains unchanged after passing through the bubble solenoid valve 1011. In the closed state, the raw water passes through the bubble solenoid valve 1011 to form micro-bubble water.

[0078] Specifically, the bubbler solenoid valve 1011 is an integrated component of a bubbler and a solenoid valve. For example, the bubbler can be installed in the internal passage of the solenoid valve. When the bubbler solenoid valve 1011 is turned on, the water flows directly through the bubbler solenoid valve 1011 without passing through the bubbler, and the water flows in the original water form; when the bubbler solenoid valve 1011 is closed, the water flows through the bubbler and is formed into micro-bubble water under the action of the bubbler. Among them, the specific structure of the bubbler is the same as that in the prior art, which is not repeated or limited here. In this embodiment, the bubbler and the solenoid valve are integrated as the micro-bubble water generating component 101, which can simplify the structure of the water purification system.

[0079] Based on the structure of the microbubble water generating component 101, controlling the microbubble water generating component 101 to work mentioned in the above embodiment is to control the bubble solenoid valve 1011 to be closed, and the raw water is converted into microbubble water through the bubble solenoid valve 1011; controlling the microbubble water generating component 101 to stop working is to control the bubble solenoid valve 1011 to be open, and the raw water directly flows through the bubble solenoid valve 1011.

[0080] Of course, in other embodiments, the microbubble water generating assembly 101 may include a solenoid valve and a bubbler, which are arranged in parallel. When executing the direct flushing program and the circulating flushing program, the control board controls the solenoid valve to close, and the raw water flows to the pipeline where the bubbler is located; when executing the drainage program and the pure water intake mode, the control board controls the solenoid valve to open, and the raw water flows to the pipeline where the solenoid valve is located.

[0081] Optional, you can continue to refer to Figure 1 The water purification system also includes a microbubble water pipeline 70, the water inlet end of the microbubble water pipeline 70 is connected to the second end of the water inlet pipeline 10, and the water outlet end of the microbubble water pipeline 70 is connected to the water outlet faucet B; a microbubble water solenoid valve 701 is provided in the microbubble water pipeline 70, and the microbubble water solenoid valve 701 is used to control the connection and disconnection of the microbubble water pipeline 70 and the water inlet pipeline 10.

[0082] Among them, the micro-bubble water solenoid valve 701 is electrically connected to the control board, and the water inlet purification system also includes a micro-bubble water intake mode. When the user needs to take micro-bubble water, the control board controls the water purification system to enter the micro-bubble water intake mode. Specifically, the water inlet solenoid valve 103, the booster pump 105, the air pump 301 and the micro-bubble water solenoid valve 701 can be controlled to open, the water purification solenoid valve 202, the reflux solenoid valve 601, the concentrated water solenoid valve 501 and the bubble solenoid valve 1011 can be closed, and the flow control valve 1061 is adjusted to a preset opening range (to ensure that the pressure value at the pressure detection component 107 is within the preset pressure value range). The raw water is roughly filtered through the first filter element 102, and enters the air dissolving tank 104 after being depressurized by the water-gas ratio adjustment mechanism 106; the outside air enters the air dissolving tank 104 after passing through the air pump 301 and the second one-way valve 302, and is dissolved in the water through the air dissolving tank 104; the water-gas mixture is pressurized by the booster pump 105, and then the pressure is released through the bubble solenoid valve 1011 to produce micro-bubble water, and flows out from the water outlet faucet B through the micro-bubble water solenoid valve 701.

[0083] For example, the working process of the water purification system provided by the embodiment of the utility model is specifically introduced below. First, the water purification system is started;

[0084] In the pure water intake mode, the water inlet solenoid valve 103, the booster pump 105, the foaming solenoid valve 1011, the clean water solenoid valve 202, the concentrated water solenoid valve 501 and the concentrated water outlet valve 502 are controlled to open, the reflux solenoid valve 601 and the air pump 301 are closed, and the flow control valve 1061 is adjusted to the maximum opening. The raw water is filtered by the reverse osmosis membrane filter assembly 40 to become pure water and concentrated water. The pure water flows to the clean water pipeline 20 through the first water outlet 40b. When the user turns on the water outlet faucet B, the pure water flows out from the water outlet faucet B; the concentrated water flows to the concentrated water pipeline 50 through the second water outlet 40c, and is finally discharged to the sewer from the concentrated water outlet C.

[0085] In the microbubble water intake mode, the water inlet solenoid valve 103, the booster pump 105, the air pump 301 and the microbubble water solenoid valve 701 are controlled to be open, the reflux solenoid valve 601, the concentrated water solenoid valve 501 and the bubble solenoid valve 1011 are closed, and the flow control valve 1061 is adjusted to a preset opening range. The raw water is roughly filtered through the first filter element 102, and enters the air dissolving tank 104 after being depressurized by the water-gas ratio adjustment mechanism 106; the outside air enters the air dissolving tank 104 after passing through the air pump 301 and the second one-way valve 302, and is dissolved in the water through the air dissolving tank 104; the water-gas mixture is pressurized by the booster pump 105, and then the pressure is released by the bubble solenoid valve 1011 to produce microbubble water, and flows out from the water outlet faucet B through the microbubble water solenoid valve 701.

[0086] In the cleaning mode, the water inlet solenoid valve 103, the air pump 301, the booster pump 105, the concentrated water solenoid valve 501 and the concentrated water outlet valve 502 are first controlled to open, and the other components are closed to execute the direct flushing program. Further, after the direct flushing program executes the preset flushing time, the booster pump 105 and the reflux solenoid valve 601 are controlled to open, and the other components are closed to execute the circulation flushing program. When the impurity parameter meets the first preset parameter, the water purification system is controlled to enter the drainage program; when the impurity parameter does not meet the preset parameter, the circulation flushing program continues to be executed. In the drainage program, the water inlet solenoid valve 103, the booster pump 105, the foaming solenoid valve 1011, the concentrated water solenoid valve 501 and the concentrated water outlet valve 502 are controlled to open, and the flow control valve 1061 is adjusted to the maximum opening, and the other components are closed. After the drainage program executes the preset drainage time, the direct flushing program is entered again, and the direct flushing program, the circulation flushing program and the drainage program are executed cyclically. Before executing the next direct flushing program, it can be determined whether the impurity parameter meets the second preset parameter. If so, the drainage program is immediately entered again to end the cleaning mode after the microbubble water is discharged; if not, the direct flushing program is continued.
