[0060] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0061] To purify water, a water purification system first filters tap water entering the system's water inlet through a filter cartridge assembly, performing other water treatment processes. Minerals are then added to the filtered water as needed. A filter cartridge assembly can consist of one or more filter cartridges connected in sequence. These filter cartridges can include pre-treatment filters, reverse osmosis filters, KDF filters, and softening filters. Pre-treatment filters primarily remove large impurities such as silt, rust, and suspended solids, and absorb residual chlorine, odor, color, and some organic and chemical contaminants. Reverse osmosis filters primarily filter out smaller particles, bacteria, viruses, certain chemicals, and even minerals. When equipped with a reverse osmosis membrane, they can also effectively remove dissolved solids, including various salts. Kinetic Degradation Fluxion (KDF) filters primarily remove heavy metals (such as lead and mercury) and inhibit bacterial growth. Softening filters primarily remove hardness minerals (calcium and magnesium) and prevent scale formation.

[0062] At present, in the relevant technology, the water source passes through two pipes, one pipe is connected to the reverse osmosis filter element in the water inlet system to obtain pure water, and the other pipe is connected to the mineral filter element in the water inlet system to obtain mineral water. However, the filtration of the water source by the mineral filter element can make the water source have beneficial elements, but the purification effect of the water source is limited, which cannot meet the user's requirements for water quality, resulting in a poor user experience.

[0063] Please also refer to Figures 1 to 2 , an embodiment of the present application provides a water purification system 100 and a water purification device, the water purification system 100 includes a pure water pipeline 100a, a mineral water pipeline 100b, a pre-treatment filter element 103, a reverse osmosis filter element 104 and a mineralized filter element 105, the pure water pipeline 100a includes a first water outlet valve 101, the mineral water pipeline 100b includes a second water outlet valve 102, the water inlet of the pre-treatment filter element 103 is connected to the system water inlet 106, the water inlet of the reverse osmosis filter element 104 is connected to the water outlet of the pre-treatment filter element 103, the water outlet of the reverse osmosis filter element 104 is connected to the system water outlet through the pure water pipeline 100a and the mineral water pipeline 100b, the mineralized filter element 105 is installed in the mineral water pipeline 100b, and at least one of the first water outlet valve 101 and the second water outlet valve 102 can adjust the water flow rate.

[0064] The first outlet valve 101 and the second outlet valve 102 can be manually operated. Alternatively, the first outlet valve 101 and the second outlet valve 102 can be electrically operated, i.e., solenoid valves, electric valves, etc., without specific limitation herein. The pure water pipeline 100a and the mineral pipeline can be made of one or more materials such as PVC, PE, PP, stainless steel, copper pipe, etc., without specific limitation herein.

[0065] The pre-treatment filter element 103 can be one or more of a stainless steel filter element, a PP cotton filter, a ceramic filter, a compression filter, and an activated carbon filter, etc., and is not specifically limited here. The pre-treatment filter element 103 can remove visible impurities such as mud, rust, and insect eggs in the water.

[0066] The reverse osmosis filter element 104 can be composed of one or more of cellulose acetate and polyamide. The main functions of the reverse osmosis filter element 104 include filtering microorganisms, removing suspended matter, removing organic matter, removing heavy metals, etc., thereby effectively purifying water quality and ensuring the safety and hygiene of water quality.

[0067] It is understood that after passing through the reverse osmosis filter element 104, the water will branch into two channels: one for entering the pure water pipeline 100a, and the other for entering the mineral water pipeline 100b. The direction of the water flow is controlled by operating the first outlet valve 101 and the second outlet valve 102. It should be noted that when tap water enters the water purification system 100 through the system water inlet 106, it has a certain water pressure, which allows water molecules in the reverse osmosis filter element 104 to pass through the membrane in the opposite direction of natural osmosis to obtain pure water, while impurities are blocked on one side of the membrane, thereby achieving the separation of water and impurities.

[0068] The mineralized filter element 105 is installed in the mineral water pipeline 100b. When the second water outlet valve 102 is opened, the water filtered by the reverse osmosis filter element 104 enters the mineral water pipeline 100b and flows out from the system water outlet 107 after passing through the mineralized filter element 105.

[0069] The primary function of the mineralized filter 105 is to replenish minerals and improve water quality. Furthermore, it regulates the water's pH. By adjusting the water's pH to a slightly alkaline level, the mineralized filter 105 improves the water's taste and nutritional value, making it more suitable for human health. This treated water is not only healthier but also boasts improved permeability, diffusion, and solubility, thereby enhancing its overall quality.

[0070] Mineralized filter element 105 is primarily composed of medical stone, a non-toxic, harmless composite mineral or medicinal rock with a certain degree of biological activity. Its chemical composition includes the common elements Ca, Mg, Si, Al, Fe, K, and Na, as well as small amounts of rare elements, rare earth elements, and radioactive elements. Medical stone exhibits properties such as adsorption, solubility, pH adjustment, biological activity, and mineralization.

[0071] See also Figure 3 When the user needs pure water, close the second water outlet valve 102, then open the first water outlet valve 101, and tap water enters the water purification system 100 from the system water inlet 106. The tap water is first filtered once by the pre-treatment filter element 103, and then filtered twice by the reverse osmosis filter element 104 to obtain pure water. Finally, it is discharged from the pure water outlet through the pure water pipe.

[0072] See also Figure 4 When the user needs mineral water with the highest concentration, close the first water outlet valve 101, then open the second water outlet valve 102, and tap water enters the water purification system 100 from the system water inlet 106. The tap water is first filtered once through the pre-treatment filter element 103, and then filtered twice through the reverse osmosis filter element 104 to obtain pure water. Subsequently, it is filtered three times through the mineralization filter element 105 to obtain mineral water, and finally discharged from the mineral water outlet through the mineral water pipeline 100b.

[0073] See also Figure 5 When the user needs to adjust the concentration of mineral water, for ease of understanding, taking the first water outlet valve 101 as an example of an adjustable water flow rate, the second water outlet valve 102 is opened and the water flow rate at the first water outlet valve 101 is adjusted. Tap water enters the water purification system 100 from the system water inlet 106, is first filtered by the pre-treatment filter element 103, and then filtered twice by the reverse osmosis filter element 104. It is then divided into the pure water pipeline 100a and the mineral water pipeline 100b. When the water flow rate at the first water outlet valve 101 is reduced, the flow rate of the pure water pipeline 100a will decrease, and the ratio of mineral water to pure water flowing out of the system water outlet 107 will increase, resulting in mineral water with a higher concentration. When the water flow rate at the first water outlet valve 101 is increased, the flow rate of the pure water pipeline 100a will increase, and the ratio of mineral water to pure water flowing out of the system water outlet 107 will decrease, resulting in mineral water with a lower concentration.

[0074] Conversely, taking the example of a second water outlet valve 102 that can adjust the water flow rate, opening the first water outlet valve 101 and adjusting the water flow rate at the second water outlet valve 102, when the water flow rate at the second water outlet valve 102 is reduced, the flow rate of the mineral water pipeline 100b will decrease, and the ratio of mineral water to pure water flowing out of the system water outlet 107 will decrease, resulting in mineral water with a lower concentration. When the water flow rate at the second water outlet valve 102 is increased, the flow rate of the mineral water pipeline 100b will increase, and the ratio of mineral water to pure water flowing out of the system water outlet 107 will increase, resulting in mineral water with a higher concentration.

[0075] The first water outlet valve 101 and the second water outlet valve 102 may be one of which can adjust the water flow rate, or the first water outlet valve 101 and the second water outlet valve 102 may both be able to adjust the water flow rate, which is not specifically limited here.

[0076] The water purification system 100 in the embodiment of the present application connects the pre-treatment filter element 103, the reverse osmosis filter element 104, and the mineralization filter element 105 in series. After the reverse osmosis filter element 104 filters the water, the mineral water is obtained through the mineralization filter element 105, thereby improving the water quality of the mineral water and thus enhancing the user experience. At the same time, the user can choose to open the first water outlet valve 101 or the second water outlet valve 102 according to their needs to obtain pure water or mineral water, thereby facilitating user use. The user can also adjust the water flow rate through one of the first water outlet valve 101 and the second water outlet valve 102 to obtain the desired concentration of mineral water, thereby enhancing the user experience.

[0077] See also Figure 2In some embodiments of the present application, the water purification system 100 further includes a housing 119 having a first water inlet, a first water outlet, a second water inlet, and a second water outlet. The pre-treatment filter element 103 and the mineralized filter element 105 are both mounted within the housing 119. The first water inlet and the first water outlet are in communication with the pre-treatment filter element 103, while the second water inlet and the second water outlet are in communication with the mineralized filter element 105. The system water inlet 106 is in communication with the first water inlet, while the water inlet of the reverse osmosis filter element 104 is in communication with the first water outlet. The water outlet of the reverse osmosis filter element 104 is in communication with the second water inlet, while the system water outlet 107 is in communication with the second water outlet. With this arrangement, the pre-treatment filter element 103 and the mineralized filter element 105 are disposed within the same housing 119, thereby simplifying the structure of the water purification system 100. Furthermore, the housing 119 can protect the pre-treatment filter element 103 and the mineralized filter element 105. The housing 119 can also be used to protect the water purification system 100, which is not specifically limited herein. The housing 119 can be made of a metal material or a harder plastic material, which is not specifically limited herein.

[0078] It should be noted that the outer shell 119 is provided with a first inner cavity 1191 and a second inner cavity 1192. The first inner cavity 1191 is connected to the first water inlet and the first water outlet. The pre-treatment filter element 103 is installed in the first inner cavity 1191 and divides the first inner cavity 1191 into a first water inlet channel 1193 and a first water outlet channel 1194. The first water inlet channel 1193 is connected to the first water inlet, and the first water outlet channel 1194 is connected to the first water outlet.

[0079] After the tap water at the system water inlet 106 flows to the first water inlet, the tap water will enter the first water inlet channel 1193 through the first water inlet, and then enter the first water outlet channel 1194 after being filtered by the pre-treatment filter element 103, and flow out from the first water outlet.

[0080] The second inner cavity 1192 is connected to the second water inlet and the second water outlet. The mineralized filter element 105 is installed in the second inner cavity 1192 and divides the second inner cavity 1192 into a second water inlet channel 1195 and a second water outlet channel 1196. The second water inlet channel 1195 is connected to the second water inlet, and the second water outlet channel 1196 is connected to the second water outlet.

[0081] When the second water outlet valve 102 is opened, the water filtered by the reverse osmosis filter element 104 flows to the second water inlet, and then enters the second water inlet channel 1195 through the second water inlet, and then enters the second water outlet channel 1196 after being filtered by the mineralized filter element 105, and flows out from the second water outlet.

[0082] There are many ways to set up the first inner cavity 1191 and the second inner cavity 1192. The first inner cavity 1191 and the second inner cavity 1192 are spaced apart in the vertical direction. The first inner cavity 1191 and the second inner cavity 1192 can also be spaced apart in the horizontal direction. One of the first inner cavity 1191 and the second inner cavity 1192 is arranged in a ring shape and is located outside the other. No specific limitation is made here.

[0083] Preferably, one of the first inner cavity 1191 and the second inner cavity 1192 is annular and located outside the other. For ease of explanation, the annular configuration of the first inner cavity 1191 is used as an example. In this case, the pre-treatment filter element 103 is annular, and the first water inlet channel 1193 and the first water outlet channel 1194 are also annular. This increases the contact area between the pre-treatment filter element 103 and the tap water, thereby improving the filtration efficiency of the pre-treatment filter element 103. Conversely, taking the annular configuration of the second inner cavity 1192 as an example, the mineralized filter element 105 is annular, and the second water inlet channel 1195 and the second water outlet channel 1196 are also annular. This increases the contact area between the mineralized filter element 105 and the water filtered by the reverse osmosis filter element 104, thereby improving the filtration efficiency of the mineralized filter element 105.

[0084] TDS (Total Dissolved Solids) stands for Total Dissolved Solids. Dissolved solids are any minerals, salts, metals, cations, or anions dissolved in water. Total dissolved solids include inorganic salts like calcium, magnesium, potassium, and sodium, as well as small amounts of water-soluble organic matter. In other words, TDS refers to all substances in water that are invisible to the naked eye. It measures the turbidity of water, meaning the lower the TDS content, the purer the water.

[0085] When the water purification system 100 stops operating and water no longer flows within it, a portion of the concentrate and permeate remain on both sides of the reverse osmosis filter element 104's membrane. Without external pressure, an osmotic pressure difference reappears, resulting in bidirectional osmosis: pure water permeates toward the concentrated water side, and vice versa. After prolonged idle time, the salt content of the water on both sides of the reverse osmosis filter element 104's membrane becomes similar. At this point, when the user opens the first or second outlet valve 101, 102, the first glass of water that flows out of the system's water outlet 107 will have a higher TDS value. This is the first glass of water problem with water purifiers.

[0086] For this reason, see Figure 6The water purification system 100 also includes a circulation pipeline 100c, a circulation control valve 113 and a booster pump 114. One end of the circulation pipeline 100c is connected to the water outlet of the reverse osmosis filter element 104, and the other end of the circulation pipeline 100c is connected to the water inlet of the reverse osmosis filter element 104. The circulation control valve 113 is installed on the circulation pipeline 100c; the water inlet of the booster pump 114 is connected to the other end of the circulation pipeline 100c, and the water outlet of the booster pump 114 is connected to the water inlet of the reverse osmosis filter element 104.

[0087] With such an arrangement, when the water purification system 100 stops working, the circulation control valve 113 is opened and the booster pump 114 is started, which can drive the water to circulate in the circulation pipeline 100c and the reverse osmosis filter element 104, thereby ensuring that the water flowing out of the water outlet of the reverse osmosis filter element 104 is always pure water. Furthermore, after being idle for a long time, when the user opens the first water outlet valve 101 or the second water outlet valve 102, the TDS value of the first cup of water flowing out of the system water outlet 107 is low, so that the user can drink the first cup of water with peace of mind.

[0088] It should be noted that the water purification equipment is provided with a controller, which is electrically connected to the first water outlet valve 101, the second water outlet valve 102, the circulation control valve 113 and the booster pump 114. When the controller detects that the first water outlet valve 101 and the second water outlet valve 102 are both in the closed state, it will open the circulation control valve 113 and start the booster pump 114 to allow water to circulate in the circulation pipeline 100c and the reverse osmosis filter element 104.

[0089] The controller can control the circulation control valve 113 to remain open and the booster pump 114 to operate, thereby maintaining the water flow in the circulation pipeline 100c and the reverse osmosis filter 104. The controller can also periodically open the circulation control valve 113 and periodically activate the booster valve to ensure that the water flow is regularly maintained in the circulation pipeline 100c and the reverse osmosis filter 104. Preferably, the controller periodically opens the circulation control valve 113 and periodically activates the booster valve, thereby reducing the power consumption of the water purification system 100 and the loss of the reverse osmosis filter 104.

[0090] Further, see Figure 6 The water purification system 100 further includes a first one-way valve 115 installed in the circulation pipeline 100c. The first one-way valve 115 is used to prevent water at the water outlet of the pre-treatment filter element 103 from flowing into the circulation pipeline 100c. This arrangement ensures that the water in the circulation pipeline 100c flows from the water outlet of the reverse osmosis filter element 104 to the water inlet of the reverse osmosis filter element 104, and prevents water at the water outlet of the pre-treatment filter element 103 from directly entering the pure water pipeline 100a or the mineral water pipeline 100b through the circulation pipeline 100c.

[0091] In some embodiments of the present application, the reverse osmosis filter element 104 is provided with two water inlets, which are respectively connected to the pre-treatment filter element 103 and the circulation pipeline 100c. In this configuration, the water filtered by the pre-treatment filter element 103 enters the reverse osmosis filter element 104 through one water inlet, and the water in the circulation pipeline 100c enters the reverse osmosis filter element 104 through the other water inlet, thereby preventing the water filtered by the pre-treatment filter element 103 from directly entering the circulation pipeline 100c.

[0092] See also Figure 6 In some embodiments of the present application, the water purification system 100 further includes a first common pipeline 100d, one end of which is connected to the water inlet of the reverse osmosis filter element 104, and the other end of which is connected to the water outlet of the pre-treatment filter element 103 and the circulation pipeline 100c. A booster pump 114 is installed in the first common pipeline 100d, and the water inlet of the booster pump 114 is connected to the water outlet of the pre-treatment filter element 103 and the circulation pipeline 100c. It can be understood that one end of the circulation pipeline 100c is located between the water outlet of the pre-treatment filter element 103 and the water inlet of the reverse osmosis filter element 104.

[0093] With this arrangement, when the circulation control valve 113 is closed and the first water outlet valve 101 or the second water outlet valve 102 is open, tap water enters the water purification system 100 from the system water inlet 106, is filtered by the pre-treatment filter element 103, and then enters the first common pipeline 100d. Under the pressure of the booster pump 114, it enters the reverse osmosis filter element 104, thereby improving the filtration efficiency of the reverse osmosis filter element 104 and, in turn, the water purification efficiency of the water purification system 100. At the same time, the booster pump 114 can drive the water to circulate within the circulation pipeline 100c and the reverse osmosis filter element 104, and the booster pump 114 can also increase the pressure of the water entering the reverse osmosis filter element 104.

[0094] See also Figure 7 In some embodiments of the present application, the water purification system 100 further includes a connecting pipe 100e, one end of which is connected to the water outlet of the reverse osmosis filter element 104, and the other end of which is connected to the system pipeline machine interface 116. With this arrangement, the water purification system 100 can be connected to a pipeline machine via the system pipeline machine interface 116, thereby improving the practicality of the water purification system 100.

[0095] The water outlet method of a pipeline air conditioner can be mechanical, solenoid-controlled, or inductively controlled, without specific limitations here. The function of a pipeline air conditioner can be either warming or cooling, without specific limitations here. The cooling method of a pipeline air conditioner with a cooling function can be either electronic or compressor, without specific limitations here.

[0096] In some embodiments of the present application, the reverse osmosis filter element 104 is provided with two water outlets, which are respectively connected to the pure water pipeline 100a and the mineral water pipeline. In this way, the pure water pipeline 100a and the mineral water pipeline 100b are separated by the two water outlets, thereby preventing the water in one of the pure water pipeline 100a and the mineral water pipeline 100b from flowing back into the other pipeline.

[0097] In some embodiments of the present application, the reverse osmosis filter element 104 is provided with three water outlets, which are respectively connected to the pure water pipeline 100a, the mineral water pipeline 100b and the circulation pipeline 100c. In this way, the pure water pipeline 100a, the mineral water pipeline 100b and the circulation pipeline 100c are separated by the three water outlets, thereby preventing the water in one of the pure water pipeline 100a, the mineral water pipeline 100b and the circulation pipeline 100c from flowing back into other pipelines.

[0098] In some embodiments of the present application, the reverse osmosis filter element 104 is provided with four water outlets, which are respectively connected to the pure water pipeline 100a, the mineral water pipeline 100b, the circulation pipeline 100c, and the connecting pipeline 100e. This arrangement separates the pure water pipeline 100a, the mineral water pipeline 100b, the circulation pipeline 100c, and the connecting pipeline 100e through the four water outlets, thereby preventing water in one of the pure water pipeline 100a, the mineral water pipeline 100b, the circulation pipeline 100c, and the connecting pipeline 100e from flowing back into the other pipelines.

[0099] See also Figure 5 In some embodiments of the present application, the water purification system 100 further includes a second common pipeline 100f. One end of the second common pipeline 100f is connected to the water outlet of the reverse osmosis filter element 104, and the other end of the second common pipeline 100f is connected to the pure water pipeline 100a and the mineral water pipeline 100b. This arrangement allows water to flow to the pure water pipeline 100a and the mineral water pipeline 100b separately simply by connecting the second common pipeline 100f, thereby simplifying the structure of the reverse osmosis filter element 104.

[0100] Please also refer to Figures 5 and 6 In some embodiments of the present application, the water purification system 100 further includes a second common pipeline 100f. One end of the second common pipeline 100f is connected to the water outlet of the reverse osmosis filter element 104, and the other end of the second common pipeline 100f is connected to the pure water pipeline 100a, the mineral water pipeline 100b, and the circulation pipeline 100c. This arrangement allows water to flow to the pure water pipeline 100a, the mineral water pipeline 100b, and the circulation pipeline 100c separately simply by routing the second common pipeline 100f, thereby simplifying the structure of the reverse osmosis filter element 104.

[0101] Please also refer to Figures 5 to 7 In some embodiments of the present application, the water purification system 100 further includes a second common pipeline 100f. One end of the second common pipeline 100f is connected to the water outlet of the reverse osmosis filter element 104, and the other end of the second common pipeline 100f is connected to the pure water pipeline 100a, the mineral water pipeline 100b, the circulation pipeline 100c, and the connecting pipeline 100e. This arrangement allows water to flow to the pure water pipeline 100a, the mineral water pipeline 100b, the circulation pipeline 100c, and the connecting pipeline 100e separately simply by routing the second common pipeline 100f, thereby simplifying the structure of the reverse osmosis filter element 104.

[0102] See also Figure 1 In some embodiments of the present application, the water purification system 100 further includes a second one-way valve 117. The water outlet of the reverse osmosis filter element 104 is connected to the pure water pipeline 100a, the mineral water pipeline 100b, and the connecting pipeline 100e via the second one-way valve 117. The second one-way valve 117 is used to prevent water from the pure water pipeline 100a, the water inlet of the mineralized filter element 105, and the connecting pipeline 100e from flowing back to the water outlet of the reverse osmosis filter element 104. This configuration ensures that water from the water outlet of the reverse osmosis filter element 104 flows into the pure water pipeline 100a, the mineral water pipeline 100b, and the connecting pipeline 100e.

[0103] Preferably, water filtered through reverse osmosis filter element 104 first passes through one end of circulation pipeline 100c, then flows through second one-way valve 117 to pure water pipeline 100a, mineral water pipeline 100b, and connecting pipeline 100e. This arrangement prevents water from flowing into circulation pipeline 100c from pure water pipeline 100a, the water inlet of mineralized filter element 105, and connecting pipeline 100e.

[0104] Further, see Figure 7 The water purification system 100 also includes a high-pressure switch 118, which is installed in the connecting pipe 100e. It should be noted that the second one-way valve 117 maintains pressure at the end of the high-pressure switch 118 closest to the first one-way valve 115. With this arrangement, when the pipeline water heater needs water replenishment, the pipeline water heater inlet control valve opens. At this time, because the second one-way valve 117 maintains pressure at the end of the high-pressure switch 118 closest to the second one-way valve 117, the opening of the pipeline water heater inlet control valve causes the pressure at the other end of the high-pressure switch 118 to drop. As a result, the high-pressure switch 118 detects the pressure drop in the connecting pipe 100e and opens, allowing water filtered by the reverse osmosis filter 104 to enter the pipeline water heater through the connecting pipe 100e and the system pipeline water heater interface 116.

[0105] When the pipeline machine is filled with water, the pipeline machine water inlet control valve is closed. At this time, since the second one-way valve 117 maintains pressure on the end of the high-pressure switch 118 close to the second one-way valve 117, the closure of the pipeline machine water inlet control valve will cause the pressure at the other end of the high-pressure switch 118 to rise, so that the high-pressure switch 118 will detect the pressure increase in the connecting pipeline 100e, and then close the high-pressure switch 118 to prevent the water filtered by the reverse osmosis filter element 104 from entering the system pipeline machine interface 116.

[0106] It should also be noted that when the pipeline is not connected to the pipeline machine, the system pipeline machine interface 116 can be blocked to prevent water from flowing out of the system pipeline machine interface 116. When the system pipeline machine interface 116 is connected to the pipeline machine and the water purification system 100 is not equipped with a high-pressure switch 118, the valve on the water inlet pipeline of the pipeline machine can be controlled to control whether the system pipeline machine interface 116 is outflowing.

[0107] Specifically, the water purification equipment includes a controller, which is electrically connected to the high-pressure switch 118. When the pipeline machine needs to be replenished with water, the pipeline machine water inlet control valve is opened. At this time, the high-pressure switch 118 will detect the pressure drop in the connecting pipeline 100e and send a signal to the controller. The controller controls the high-pressure switch 118 to open. When the pipeline machine is filled with water, the pipeline machine water inlet control valve is closed. At this time, the high-pressure switch 118 will detect the pressure increase in the connecting pipeline 100e and send a signal to the controller. The controller controls the high-pressure switch 118 to close.

[0108] See also Figure 1 In some embodiments of the present application, the water purification system 100 further includes a first water quality detection probe 108, which is installed behind the water outlet of the reverse osmosis filter element 104. With such a configuration, the water quality of the water flowing out of the water outlet of the reverse osmosis filter element 104 can be detected by the first water quality detection probe 108.

[0109] Specifically, the water purification equipment includes a controller, which is electrically connected to the first water quality detection probe 108 and the first water outlet valve 101. When the first water quality detection probe 108 detects that the water quality does not meet the standards, it will send a signal to the controller. The controller will close the first water outlet valve 101 and / or the second water outlet valve 102 to prevent users from drinking substandard water.

[0110] Furthermore, the water inlet device also includes an alarm, and the controller is electrically connected to the alarm. When the first water quality detection probe 108 detects that the water quality does not meet the standard, it will send a signal to the controller, and the controller will control the alarm to work to remind the user.

[0111] See also Figure 1In some embodiments of the present application, the water purification system 100 further includes a second water quality detection probe 109, which is installed between the pre-treatment filter element 103 and the reverse osmosis filter element 104. In this arrangement, the water quality of the water filtered by the pre-treatment filter element 103 can be detected by the second water quality detection probe 109.

[0112] Specifically, the water purification equipment includes a controller, which is electrically connected to the second water quality detection probe 109, the first water outlet valve 101 and the second water outlet valve 102. When the second water quality detection probe 109 detects that the water quality does not meet the standards, it will send a signal to the controller, and the controller will close the first water outlet valve 101 and the second water outlet valve 102 to prevent users from drinking substandard water.

[0113] Furthermore, the water inlet device also includes an alarm, and the controller is electrically connected to the alarm. When the second water quality detection probe 109 detects that the water quality does not meet the standard, it will send a signal to the controller, and the controller will control the alarm to work to remind the user.

[0114] The first water quality detection probe 108 and the second water quality detection probe 109 can be selected from a total dissolved solids (TDS) probe, a conductivity probe, a pH probe, and the like.

[0115] See also Figure 1 In some embodiments of the present application, the water purification system 100 further includes a water inlet valve 110, which is installed between the system water inlet 106 and the pre-treatment filter element 103. With this arrangement, when the user needs to replace the pre-treatment filter element 103, the water inlet valve 110 can be closed to prevent tap water from flowing into the pre-treatment filter element 103, making it easier for the user to maintain the pre-treatment filter element 103.

[0116] The operation of reverse osmosis filter 104 is essentially a process of liquid concentration. As water flows through the membrane surface of reverse osmosis filter 104, the salt content in the water increases, causing the osmotic pressure of the water to also increase. As the concentration of minerals (and contaminants) in the water increases, some of these minerals (and contaminants) will deposit on the membrane surface of reverse osmosis filter 104, clogging the pores of the reverse osmosis membrane. This results in a decrease in the membrane's water output and salt rejection rate, affecting the purification effect.

[0117] For this reason, see Figure 8Water purification system 100 also includes a drain line 100g and a drain valve 112. The drain outlet of reverse osmosis filter element 104 communicates with system drain outlet 111 via drain line 100g, and drain valve 112 is mounted on drain line 100g. This arrangement allows some water to wash away minerals and contaminants deposited on the membrane surface of reverse osmosis filter element 104 and then be discharged from system drain outlet 111 through the drain outlet of reverse osmosis filter element 104 and drain line 100g. This ensures that the water production and desalination capacity of reverse osmosis filter element 104 are not reduced, thus maintaining the filtration effect.

[0118] Specifically, the water purification equipment includes a controller, which is electrically connected to the drain valve 112. The controller will periodically control the drain valve 112 to open. In this way, part of the water in the reverse osmosis filter element 104 will flush out the minerals and pollutants deposited on the membrane surface of the reverse osmosis filter element 104 and regularly discharge from the system drain outlet 111 through the drain outlet of the reverse osmosis filter element 104 and the drain pipe 100g, thereby reducing water waste.
