[0085] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0086] like Figure 1 As shown in the illustration, an embodiment of this application provides a water purification system comprising: an inlet component 110, an electro-adsorption filter component 120, a reverse osmosis filter component 130, an outlet component 140, and a water circuit control component 150. The inlets of both the electro-adsorption filter component 120 and the reverse osmosis filter component 130 are connected to the inlet component 110, and the outlet of the electro-adsorption filter component 120 is connected to the inlet of the reverse osmosis filter component 130. The outlets of both the electro-adsorption filter component 120 and the reverse osmosis filter component 130 are connected to the outlet component 140.

[0087] In this embodiment, the water inlet assembly 110 is used to receive raw water from the water inlet of the water purification system and pre-treat the raw water to remove impurities such as silt, rust, colloidal organic matter, and trace pollutants, thus achieving initial filtration of the raw water. In practical applications, the water inlet assembly 110 includes a water tank 113 for storing a portion of the pre-filtered raw water, so that the water purification system can meet the user's water demand when the user takes a large amount of water.

[0088] In this embodiment, the electro-adsorption filtration component 120 is used to remove charged substances from water, including anions and cations, such as K+. + Ca 2+ Pb 2+ Cl - HCO 3- SO4 2-In practical applications, the electro-adsorption filter component 120 uses electro-purification and desalination technology to remove charged substances. The working principle of electro-purification and desalination technology is as follows: two porous carbon materials are used as electrode materials. After applying positive and negative charges to the electrode materials respectively, when water flows through the water channel between the two electrodes, charged ions in the water with opposite polarities to the electrode materials migrate to the electrode materials under the drive of the electric field and are adsorbed and removed, thereby achieving water desalination.

[0089] In practical applications, when the electrode material becomes saturated with adsorption, its regeneration can be achieved by reversing the connection of the positive and negative electrodes. After reversing the connection, the anions and cations adsorbed by the positive and negative electrodes will detach from the electrode material under electrostatic repulsion after the electrode polarity changes. Driven by the water flow, they are then discharged from the water pipes, thus regenerating the electrode material. The voltage required to provide the electric driving force during operation is generally in the low voltage range (<2.5V), resulting in low energy consumption. Furthermore, the regeneration capability of the electrode material significantly extends its service life.

[0090] In this embodiment, the reverse osmosis filter assembly 130 is used to remove impurities such as metal ions and organic matter from the water. It should be noted that the reverse osmosis filter assembly 130 can be used alone in a water purification system, or it can be used in conjunction with the electro-adsorption filter assembly 120 to provide users with filtered water that meets their water quality requirements.

[0091] In this embodiment, the water outlet assembly 140 is used to perform end-of-pipe water treatment functions such as intercepting toner in the water path and improving taste. The water outlet assembly 140 includes the water outlet of the water purification system, which can be configured as any type of faucet to provide users with filtered water.

[0092] In this embodiment, the water circuit control component 150 includes a water valve, a reversing valve, a check valve 133, a water pump, etc., and is used to limit the conduction state of the water circuit, the direction of water flow, and the water flow velocity, etc., of the water flow parameters. It should be noted that the specific type of the water circuit control component 150 can be selected according to the actual application scenario. In this embodiment, the water circuit control component 150 can be replaced with a device having equivalent functions.

[0093] In practical applications, the water purification system also includes a controller, which is connected to each water circuit control component 150 and the electro-adsorption filtration component 120 to control the water flow through different components sequentially according to the corresponding water circuits in the water purification system, thereby achieving the supply of water with different water quality parameters. Furthermore, the controller can control the electro-adsorption module in the electro-adsorption filtration component 120 to switch between brine absorption mode and regeneration mode based on the usage status of the corresponding electro-adsorption module, ensuring that while supplying water, there is sufficient time for the electro-adsorption module to complete its regeneration.

[0094] In this embodiment, the water path control component 150 is disposed between the water path pipes of the water purification system. The water path control component 150 is used to control the water to flow from the inlet component 110 through the electro-adsorption filter component 120 and / or the reverse osmosis filter component 130 to the outlet component 140 according to the water purification mode.

[0095] In practical applications, the flow paths of water in a water purification system include five types:

[0096] In the first scenario, when the water purification mode is set to the first mode, water flows from the inlet component 110 through the electro-adsorption filter component 120 to the outlet component 140. The specific flow path is as follows: Figure 4 As shown.

[0097] The second scenario involves water flowing from the inlet component 110 through the reverse osmosis filter component 130 to the outlet component 140, with the specific flow path as follows: Figure 6 As shown.

[0098] The third method involves water flowing from the inlet component 110 through the electro-adsorption filter component 120 and the reverse osmosis filter component 130 to the outlet component 140. The specific flow path is as follows: Figure 7 As shown.

[0099] Fourthly, in the fourth water purification mode, water flows from the inlet component 110 through the electro-adsorption filter component 120 and the reverse osmosis filter component 130 to the outlet component 140. The specific flow path is as follows: Figure 8 As shown.

[0100] The fifth type is where water flows directly from the inlet component 110 to the outlet component 140.

[0101] In this embodiment, the fifth method will only be activated when neither the electroadsorption filter assembly 120 nor the reverse osmosis filter assembly 130 can achieve effective filtration. In a specific embodiment, such as... Figure 2 As shown, the water body will flow sequentially through the first filter element 111, the second filter element 112, the third water valve 158, the second reversing valve, the check valve 133, and the post-treatment filter element 141 to the outlet of the water purification system.

[0102] In this embodiment, the water purification modes include a first mode, a second mode, a third mode, and a fourth mode. Under different purification modes, the filtered water provided by the water purification system has different drinking effects. Specifically, the first mode can be referred to as a standalone electroadsorption water production mode, the second mode as a standalone reverse osmosis membrane water production mode, the third mode as a reverse osmosis membrane-assisted electroadsorption combined purification water production mode, and the fourth mode as a reverse osmosis + electroadsorption hybrid water production mode. It should be noted that in the first and fourth modes, the filtered water provided by the water purification system contains some non-charged substances, such as metasilicic acid, which can provide users with mineral-rich drinking water. In the second and third modes, the water purification system can achieve thorough filtration of the water, providing users with cleaner drinking water.

[0103] In a specific embodiment, in the third mode, the electro-adsorption filter component 120 can serve as the water supply end of the reverse osmosis filter component 130, providing the reverse osmosis filter component 130 with soft water that has removed multivalent ions, thereby effectively extending the lifespan of the reverse osmosis filter element 131. In the fourth mode, the electro-adsorption filter component 120 can operate at a lower load, providing a longer time for the regeneration mode of the electro-adsorption module, thereby ensuring the complete regeneration of the electrode material.

[0104] In this embodiment, the specific water purification mode settings can be customized by the user through the control panel or control buttons of the water purifier, or automatically configured by a pre-configured program on the water purifier. For example, the default water purification mode is mode four, switching to another mode only when the current mode fails. The specific switching order can be mode four, mode three, mode two, and mode one. It should be noted that the automatic switching order of the water purification modes can be customized according to the actual application scenario. It should also be noted that the control panel and control buttons of the water purifier can be adaptively designed according to the needs of the actual application scenario.

[0105] In summary, this embodiment provides a water purification system that can automatically switch water purification modes according to the user's water purification needs. In actual use, it not only provides users with safe and healthy drinking water but also automatically maintains the filter components, greatly extending their lifespan. By using different water flow directions, it achieves flexible adjustment of drinking water quality, meeting the diverse needs of users for drinking water quality.

[0106] In one embodiment, such as Figure 2As shown, the electro-adsorption filtration assembly 120 includes a first electro-adsorption module 121 and a second electro-adsorption module 122. The water inlet assembly 110 is connected to the water inlet of the first electro-adsorption module 121 and the water inlet of the second electro-adsorption module 122, respectively. The water outlet of the first electro-adsorption module 121 and the water outlet of the second electro-adsorption module 122 are connected to the water inlet of the reverse osmosis filtration assembly through a first water flow branch, connected to the water outlet assembly 140 through a second water flow branch, and connected to the wastewater outlet of the water purification system through a third water flow branch.

[0107] When the electro-adsorption filter component 120 is in operation, the water circuit control component 150 controls the water to flow through the first electro-adsorption module 121 or the second electro-adsorption module 122 to the water flow branch corresponding to the water purification mode.

[0108] In this embodiment, the main function of the first electroadsorption module 121 and the second electroadsorption module 122 is to remove charged substances from the water, including cations and anions, such as K+. + Ca 2+ Pb 2+ Cl - HCO 3- SO4 2- The working principle of the electroadsorption module in this embodiment is as follows: Figure 3 As shown, it should be noted that the electroadsorption module in this embodiment can be either an electroadsorption module without an ion exchange membrane or an electroadsorption module with an ion exchange membrane. The core components of the electroadsorption module without an ion exchange membrane performing desalination include a current collector, electrode material adhered to the surface of the current collector (the effective ion removal component is an adsorbent carbonaceous material, or other materials with ion adsorption capacity, or a composite material composed of carbon and other materials with ion adsorption capacity), and a DC power supply for controlling the voltage. In contrast, when the electroadsorption module with an ion exchange membrane is performing desalination, the anion exchange membrane is close to the positive electrode, and the cation exchange membrane is close to the negative electrode; the anion exchange membrane and cation exchange membrane only allow anions and cations to pass through, respectively.

[0109] refer to Figure 3 The working principle of the electro-adsorption module without ion exchange membrane in desalination mode is as follows: Figure 3 As shown in (A), the working principle in regeneration mode is as follows: Figure 3 As shown in (B), the working principle of the electro-adsorption module with ion exchange membrane in desalination mode is as follows. Figure 3 As shown in (C), the working principle in regeneration mode is as follows: Figure 3 As shown in (D).

[0110] In this embodiment, the electro-adsorption filtration assembly 120 includes at least two electro-adsorption modules, which can achieve the control of one electro-adsorption module for desalination and water production, and the other electro-adsorption module for regeneration. This allows the electro-adsorption filtration assembly 120 to continuously supply drinking water with filtered positive and negative ions to the water purification system while performing regeneration.

[0111] In one embodiment, such as Figure 4 and Figure 5 As shown, the water circuit control component 150 includes a first directional valve 151, a second directional valve 152, and a third directional valve 153. It should be noted that the directional valve in this embodiment is a three-way valve; in practical applications, the directional valve can be replaced by other types of multi-way valves that can achieve the same function.

[0112] The first end of the first reversing valve 151 is connected to the outlet of the first electro-adsorption module 121, the second end of the first reversing valve 151 is connected to the outlet of the second electro-adsorption module 122, and the third end of the first reversing valve 151 is connected to the first end of the second reversing valve 152.

[0113] The second end of the second reversing valve 152 is connected to the inlet water assembly 110 and the reverse osmosis filter assembly 130, respectively, and the third end of the second reversing valve 152 is connected to the outlet water assembly 140.

[0114] The first end of the third reversing valve 153 is connected to the outlet of the first electro-adsorption module 121, the second end of the third reversing valve 153 is connected to the outlet of the second electro-adsorption module 122, and the third end of the third reversing valve 153 is connected to the wastewater outlet.

[0115] In this embodiment, Figure 4 In the process, when the water purification mode of the water purification system is the first mode and the first electro-adsorption module 121 is in the desalination mode, the water flows from the water tank 113 through the first water pump 155, the first water valve 154, the first electro-adsorption module 121, the first end of the first reversing valve 151, the third end of the first reversing valve 151, the first end of the second reversing valve 152, the third end of the second reversing valve 152, the check valve 133, and the post-treatment filter element 141, until it flows to the outlet of the water purification system.

[0116] exist Figure 5 In the process, when the water purification mode of the water purification system is the first mode, the first electro-adsorption module 121 is in the regeneration mode and the second electro-adsorption module 122 is in the desalination mode, the regenerated water of the first electro-adsorption module 121 flows as follows: the water flows from the water tank 113 through the first water pump 155, the first water valve 154, the first electro-adsorption module 121, the first end of the third reversing valve 153, and the third end of the third reversing valve 153, until it flows to the wastewater outlet of the water purification system.

[0117] In this embodiment, the flow direction of the first, second, and third water flow branches in the aforementioned scheme can be adjusted by setting three reversing valves. In practical applications, each end of the reversing valve can be controlled to open or close as needed. For example, in the first water flow branch, the third reversing valve 153 can open the first and third ends to direct the outlet water of the first electroadsorption module 121 to the wastewater outlet. The third reversing valve 153 can also open the second and third ends to direct the outlet water of the second electroadsorption module 122 to the wastewater outlet. The first reversing valve 151 and the second reversing valve 152 can also open designated water paths, which will not be elaborated here.

[0118] Things to know, such as Figures 4-8 As shown, water paths marked with arrows indicate flowable water paths, while those without arrows indicate non-flowing water paths. The water flow direction of the water purification system can be adaptively switched on and off by the water path control component 150 according to the needs of the actual application scenario to achieve the corresponding water purification mode.

[0119] In one embodiment, the electro-adsorption filtration assembly 120 further includes a first sensor 123 and a second sensor 124. The first sensor 123 is disposed in the inlet branch of the electro-adsorption filtration assembly 120, and the second sensor 124 is disposed in the outlet branch of the electro-adsorption filtration assembly 120. In this embodiment, the first sensor 123 and the second sensor 124 can be water quality sensors, water temperature sensors, or water flow sensors, used to detect total dissolved solids, water temperature, water flow rate, or water velocity. It should be noted that the specific types of the first sensor 123 and the second sensor 124 can be configured according to the needs of the actual application scenario.

[0120] In practical applications, the health status of the first electroadsorption module 121 and the second electroadsorption module 122 includes the following various scenarios:

[0121] In the first scenario, the first desalination parameters of both the first electroadsorption module 121 and the second electroadsorption module 122 are greater than or equal to a preset parameter threshold, and either electroadsorption module enters the desalination mode.

[0122] In the second scenario, the first desalination parameter of the first electro-adsorption module 121 is greater than or equal to a preset parameter threshold, and the first desalination parameter of the second electro-adsorption module 122 is less than the preset parameter threshold. In this scenario, the first electro-adsorption module 121 enters the desalination mode, and the second electro-adsorption module 122 enters the regeneration mode.

[0123] In the third scenario, if the first desalination parameter of the first electroadsorption module 121 is less than a preset parameter threshold, and the first desalination parameter of the second electroadsorption module 122 is greater than or equal to the preset parameter threshold, the first electroadsorption module 121 enters the regeneration mode, and the second electroadsorption module 122 enters the desalination mode.

[0124] Fourthly, when the first desalination parameters of the first electroadsorption module 121 and the second electroadsorption module 122 are both less than the preset parameter threshold, both the first electroadsorption module 121 and the second electroadsorption module 122 enter the regeneration mode.

[0125] Specifically, in the first, second, and third cases, the water circuit control component 150 controls the water to flow through the electro-adsorption module in desalination mode to the water flow branch corresponding to the water purification mode.

[0126] In the fourth case, if the electro-adsorption filter assembly 120 is found to be inoperable, the water circuit control assembly 150 controls the water to flow from the inlet assembly 110 through the reverse osmosis filter assembly 130 to the outlet assembly.

[0127] It should be noted that the first desalination parameter is calculated based on the first sensing parameter detected by the first sensor 123 and the second sensing parameter detected by the second sensor 124.

[0128] In this embodiment, it is assumed that the first sensor 123 is sensor 1 and the second sensor 124 is sensor 2. The first sensor 123 is used to detect the influent water quality of the electro-adsorption module, and the second sensor 124 is used to detect the product water quality of the electro-adsorption module. The calculation formula for the first desalination parameter is as follows: It should be noted that the first desalination parameter can also be called the first desalination rate.

[0129] In one embodiment, when the electro-adsorption filtration component 120 is in operation, if the first desalination parameter of the current electro-adsorption module is greater than or equal to a preset parameter threshold, the current electro-adsorption module enters the desalination mode, and the water circuit control component 150 controls the water to flow through the current electro-adsorption module to the water flow branch corresponding to the water quality purification mode.

[0130] If the first desalination parameter of the current electro-adsorption module is less than the preset parameter threshold, the current electro-adsorption module enters the regeneration mode, and the water circuit control component 150 controls the water to flow through another electro-adsorption module to the water flow branch corresponding to the water quality purification mode.

[0131] In this embodiment, it is assumed that the desalination rate threshold of the system is R, that is, the preset parameter threshold is R. Optionally, the preset value R can be controlled within the range of 30% to 95%, and the actual value of the preset value R can be adjusted according to the different functions to be achieved.

[0132] In this embodiment, if Control the current electroadsorption module to enter desalination mode. If This controls the current electroadsorption module to enter regeneration mode.

[0133] This embodiment uses the first sensor 123 and the second sensor 124 to monitor the desalination rate of the electro-adsorption module and automatically switch the mode of the electro-adsorption module according to the desalination rate, thereby effectively ensuring the ion adsorption efficiency of the electro-adsorption module and ensuring the water production effect.

[0134] In one embodiment, the electro-adsorption filtration assembly 120 further includes a third sensor 125, which is disposed in the third water flow branch. It should be noted that the specific type of the third sensor 125 is the same as that of the first sensor 123 or the second sensor 124.

[0135] The difference between the third sensing parameter detected by the third sensor 125 and the first sensing parameter is calculated. If the difference is less than the preset difference threshold, the electro-adsorption module in regeneration mode is determined to have completed regeneration.

[0136] In this embodiment, the water quality of the wastewater generated by the electro-adsorption module is further detected by a third sensor 125. The difference between the third sensing parameter and the first sensing parameter is calculated. When the difference is less than a preset difference threshold ΔT, it is determined that the electro-adsorption module has completed regeneration. It should be noted that the preset difference threshold ΔT can be configured between 5 and 20 mg / L. The preset difference threshold can be configured according to the needs of the actual application scenario.

[0137] In one embodiment, the water circuit control component 150 includes a first water pump 155, a first water valve 154, a second water pump 157, and a second water valve 156. The first water pump 155 and the second water valve 156 are disposed in the water inlet branch of the first electro-adsorption module 121, and the second water pump 157 and the second water valve 156 are disposed in the water inlet branch of the second electro-adsorption module 122.

[0138] In this embodiment, the first water pump 155 and the second water pump 157 are used to regulate the inlet flow rate of the first electro-adsorption module 121 and the second electro-adsorption module 122, respectively. The conduction states of the first water valve 154 and the second water valve 156 correspond to the working states of the first electro-adsorption module 121 and the second electro-adsorption module 122. When the first electro-adsorption module 121 is in working mode (salt absorption mode or regeneration mode), the first water valve 154 is open. When the second electro-adsorption module 122 is in working mode (salt absorption mode or regeneration mode), the second water valve 156 is open.

[0139] In one embodiment, the water inlet assembly 110 includes a pretreatment filter cartridge and a water tank 113. The inlet of the pretreatment filter cartridge is connected to the inlet of the water purification system, and the outlet of the pretreatment filter cartridge is connected to the inlet of the water tank 113, the inlet of the reverse osmosis filter assembly 130, and the water outlet assembly 140, respectively.

[0140] The inlet of water tank 113 is connected to the inlet of reverse osmosis filter assembly 130 and the outlet of water assembly 140, respectively, and the outlet of water tank 113 is connected to the inlet of electro-adsorption filter assembly 120.

[0141] In this embodiment, the pretreatment filter element includes a first filter element 111 and a second filter element 112. The first filter element 111 can be a high-precision PP filter element (filtration accuracy <5µm, including fused-in and pleated forms) or an ultrafiltration filter element. Its main function is to remove non-charged substances such as silt, rust, and colloidal organic matter from the water, especially colloidal organic pollutants, to prevent contamination of the electro-adsorption module and coverage of effective adsorption active sites. The second filter element 112 can be a carbon filter element, including activated carbon filter element, carbon fiber filter element, or functional carbon filter element. Its main function is to adsorb and remove trace pollutants such as non-charged small molecule antibiotics and pesticide residues from the water.

[0142] Water tank 113 is mainly used to store water filtered by the first filter element 111 and the second filter element 112. It should be noted that a corresponding liquid level sensor can be installed in water tank 113 to determine whether water needs to be added. When the liquid level in water tank 113 is insufficient, the water level in water tank 113 will be lowered until the water level in water tank 113 exceeds a preset liquid level threshold.

[0143] In one embodiment, the water circuit control component 150 includes a third water valve 158 and a third water pump 159. The third water valve 158 and the third water pump 159 are arranged in the inlet branch of the reverse osmosis filter component 130. One side of the third water valve 158 is connected to the outlet of the pretreatment filter element and the inlet of the water tank 113, respectively, and the other side of the third water valve 158 is connected to the inlet of the reverse osmosis filter component 130 and the outlet component 140, respectively.

[0144] In this embodiment, the third water valve 158 and the third water pump 159 are used in conjunction with the reverse osmosis filter element 131 to supply reverse osmosis feed water. It should be noted that the first water pump 155 and the second water pump 157 can be self-priming pumps, such as self-priming pumps or peristaltic pumps, and the flow rate can be controlled by adjusting the voltage. The third water pump 159 is a booster pump, which can provide boosting and pressure-maintaining capabilities for the reverse osmosis filter element 131.

[0145] In one embodiment, the water outlet assembly 140 includes a post-treatment filter element 141, the reverse osmosis filtration assembly 130 includes a reverse osmosis filter element 131, the inlet of the post-treatment filter element 141 is connected to the outlet of the electro-adsorption filtration assembly 120, the outlet of the reverse osmosis filter element 131 and the water inlet assembly 110 respectively; the outlet of the post-treatment filter element 141 is connected to the outlet of the water purification system; the inlet of the reverse osmosis filter element 131 is connected to the water inlet assembly 110.

[0146] In this embodiment, the reverse osmosis filter element 131 is used to remove metal ions, organic matter, etc. from the water. It can be used as a supplementary treatment to the electro-adsorption module or as a separate purification unit. The reverse osmosis filter element 131 has two operating states: water production and flushing.

[0147] Post-treatment filter cartridge 141 is mainly used to intercept carbon powder in the water circuit and improve the taste. It can be a non-woven fabric or carbon filter cartridge with non-woven fabric, a filter cartridge combined with PP, an ultrafiltration and carbon composite filter cartridge, etc.

[0148] In this embodiment, the reverse osmosis filter element 131 is also connected to the third end of the second directional valve 152 via a check valve 133. The reverse osmosis filter element 131 is also connected to the wastewater outlet of the water purification system via a wastewater valve 134. The check valve 133 is used to prevent backflow of water. The wastewater valve 134 is used to facilitate cleaning of the reverse osmosis filter element 131.

[0149] The water outlet assembly 140 also includes a fifth sensor 142, which is of the same type as the aforementioned sensor. When the fifth sensor 142 detects water flow, it indicates that the water outlet assembly 140 is in the water outlet state and can provide drinking water to the user.

[0150] In one embodiment, the reverse osmosis filtration assembly 130 further includes a fourth sensor 132, which is disposed at the outlet of the reverse osmosis filtration assembly 130. A second desalination parameter is calculated based on the fourth sensing parameter, the first sensing parameter, the second sensing parameter, and the fourth sensing parameter detected by the fourth sensor 132. The water circuit control assembly 150 adjusts the inlet flow rate of the electro-adsorption module in desalination mode according to the second desalination parameter.

[0151] In this embodiment, the fourth sensor 132 is of the same type as the first sensor 123, the second sensor 124, or the third sensor 125. The fourth sensor 132 is mainly used to detect the quality of the permeate from the reverse osmosis membrane. In practical applications, water quality is generally monitored through TDS values, conductivity, etc.

[0152] In this embodiment, the formula for calculating the second desalination parameter is:

[0153]

[0154] In this sensor configuration, sensor 1 is the first sensing parameter, sensor 2 is the second sensing parameter, and sensor 3 is the fourth sensing parameter. The flow rate of reverse osmosis filter element 131 is... This refers to the water flow rate of the electroadsorption module.

[0155] In this embodiment, the controllable range of the second desalination parameter ΔR can be 30~95%, according to The measured values ​​are used to adjust the flow rate of the water pump corresponding to the current electroadsorption module to regulate the water quality.

[0156] Taking the first electroadsorption module 121 as an example, with the first sensing parameter of the first sensor 123 = 100 mg / L, the fourth sensing parameter of the fourth sensor 132 = 10 mg / L, the second sensing parameter of the second sensor 124 = 50 mg / L, and the flow rates V1 = 1 L / min and V2 = 0.5 L / min, and the preset value of ΔR being 90%, the calculated ΔR = [(100-10)*1 + (100-50)*0.5] / [(1+0.5)*100] = 76.7% < 90%. Since the desalination rate of the reverse osmosis membrane needs to be stable above 90%, the desalination rate of the electroadsorption module needs to be adjusted. The flow rate of the electroadsorption module is an important factor affecting the desalination rate. The higher the flow rate, the shorter the residence time of water in the electroadsorption module, and the lower the desalination rate. The lower the flow rate, the longer the residence time of water in the electroadsorption module, and the higher the desalination rate. Therefore, the desalination rate of the electro-adsorption module can be increased by reducing the flow rate of the first water pump 155, thereby increasing the desalination rate of the mixed water; similarly, if the desalination rate of the mixed water is too high, it can be adjusted by increasing the flow rate of the first water pump 155.

[0157] In one embodiment, when the second desalination parameter is greater than or equal to the first threshold, the water circuit control component 150 increases the inlet flow rate of the electro-adsorption module in desalination mode. When the second desalination parameter is less than or equal to the second threshold, the water circuit control component 150 decreases the inlet flow rate of the electro-adsorption module in desalination mode, wherein the first threshold is greater than the second threshold.

[0158] In this embodiment, the threshold of the second desalination parameter can be set to two different thresholds, for example, the first threshold is 95% and the second threshold is 90%. It should be noted that the actual values ​​of the first threshold and the second threshold can be configured according to the needs of the application scenario.

[0159] In summary, this embodiment provides a water purification system capable of freely switching between different water purification paths. The corresponding water purification mode can be adjusted simply by controlling the operating status of the water path control component 150 and the electro-adsorption filter component 120. The electro-adsorption filter component 120 provides two electro-adsorption modules, enabling continuous water supply while simultaneously regenerating the electro-adsorption modules. The simultaneous inclusion of the electro-adsorption filter component 120 and the reverse osmosis filter component 130 in the water purification system meets the user's flexible water supply needs. Furthermore, it effectively extends the service life of the filter components, greatly improving the flexibility of the water purification system.

[0178] S1303, when the second desalination parameter is greater than or equal to the first threshold, increase the influent flow rate of the electro-adsorption module in desalination mode.

[0179] S1304, when the second desalination parameter is less than or equal to the second threshold, the influent flow rate of the electro-adsorption module in desalination mode is reduced, wherein the first threshold is greater than the second threshold.

[0180] In summary, this embodiment provides a water purification system control method that enables free switching between different water purification circuits. The corresponding water purification mode can be adjusted simply by controlling the operating status of the water circuit control component and the electro-adsorption filtration component. The electro-adsorption filtration component provides two electro-adsorption modules, allowing for continuous water supply while the electro-adsorption modules regenerate. Equipping the water purification system with both electro-adsorption and reverse osmosis filtration components meets the user's flexible water supply needs. Furthermore, it effectively extends the service life of the filtration components, greatly improving the flexibility of the water purification system.
