[0002] Water purification equipment removes harmful substances such as suspended solids, bacteria, viruses, heavy metals, residual chlorine, and odors from water through physical or chemical means, bringing the water quality up to specific drinking or usage standards. With the gradual improvement of people's living standards, the high demand for water quality has led to the widespread adoption of water purification equipment or integrated water purification appliances in kitchens, living rooms, and bathrooms, becoming a crucial link in ensuring daily water safety and improving the quality of life.

[0003] However, most current water purification equipment uses relatively fixed and uniform standard purification methods, ignoring the real-time dynamic changes in the quality of the incoming water. In reality, the quality of raw water fluctuates significantly due to factors such as geographical environment, seasonal changes, aging pipe networks, and secondary water supply. Current water purification equipment is prone to a significant reduction in filter lifespan when the raw water quality is poor, while operating according to the standard process when the raw water quality is good wastes the filter's dirt-holding capacity and adsorption capacity, failing to achieve on-demand use. Therefore, current water purification equipment suffers from short lifespan and high operating costs. Summary of the Invention

[0050] Figure 13 This is an internal structural diagram of a computer device in one embodiment. Detailed Implementation

[0051] 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.

[0052] In one embodiment, such as Figure 1As shown, a water purification device is provided, which includes a multi-stage filtration assembly 102 connected between an inlet (not shown) and an outlet 101, multiple valve assemblies 103, a water quality detection assembly 104, and a controller (not shown) that is communicatively connected to the water quality detection assembly 104 and the valve assemblies 103 respectively.

[0053] Among them, the filter component 102 is the core component of the water purification equipment that has the function of filtering water. The filter component 102 can remove impurities, particulate matter, odors, bacteria or harmful substances in the fluid through physical interception, adsorption or chemical reaction, thereby purifying the fluid.

[0054] In the water purification equipment, the filtration level of each filter component 102 increases sequentially from the inlet to the outlet 101, and each filter component 102 is connected to the subsequent filter components 102 through a pipeline.

[0055] The inlet is where the unfiltered raw water enters the water purifier. The inlet can be connected to a water source, such as an external tap or an internal water tank. The outlet 101 is where the filtered water is discharged.

[0056] The filtration grade is a parameter used to characterize the smallest particle size or molecular weight range that the filter element 102 can retain. A higher grade indicates that it can intercept smaller particles and produce purer water. Each stage of the filter element 102 has a different filtration grade and therefore a different filtration function. For example, the earlier stages primarily filter large particles, while later stages primarily filter small impurities and adsorb odors and harmful gases. Taking a three-stage filtration system as an example, the first stage filter element can use polypropylene (PP) meltblown cotton, utilizing capillary action and mechanical interception to remove large particles such as sediment and rust. The second stage filter element can use activated carbon, such as granules or compressed carbon rods, primarily to adsorb residual chlorine, discoloration, odors in the water, and harmful gases such as formaldehyde and benzene in the air. The third stage filter element can use an RO reverse osmosis membrane to remove heavy metals, viruses, and scale, producing pure water.

[0057] Understandably, the filtration levels of each filter element 102 increase sequentially from the inlet to the outlet 101. Furthermore, each filter element 102 is connected to all subsequent filter elements 102 via piping. This means that the filter elements 102 are arranged from low to high filtration level and connected end-to-end along the direction from the inlet to the outlet 101. For example, the outlet of the first-stage filter element is connected to the inlet of the second-stage filter element, the outlet of the second-stage filter element is connected to the inlet of the third-stage filter element, and so on. Simultaneously, each filter element 102 can be connected to all subsequent filter elements 102 via piping. Taking a purification device with four stages of filtration as an example, the first-stage filter element can be connected to the second-stage filter element, as well as the third and fourth-stage filter elements via piping. Similarly, the second-stage filter element can be connected to the third-stage filter element, as well as the fourth-stage filter element via piping.

[0058] The valve assembly 103 is an electromechanical device with at least two switchable flow paths. The valve assembly 103 has at least two opening directions, and by changing its opening direction, it can open or block a specific pipeline, thereby achieving a change in water flow direction or on / off control. By installing the valve assembly 103 on the connecting pipelines of each filter assembly 102, the water flow direction can be adjusted, allowing the raw water to flow through the target filter assembly for filtration.

[0059] In one embodiment, the valve assembly 103 may be located at the branch points of the pipelines.

[0060] In one embodiment, valve assembly 103 may be a solenoid valve.

[0061] The water quality detection component 104 is a device component installed between the first-stage filtration component and the inlet, used to detect the water quality of the raw water flowing into the inlet, and capable of sensing the concentration of impurities in the water. By setting up the water quality detection component 104, the actual water quality information of the raw water can be accurately obtained, thereby determining the water quality status of the raw water, and providing an accurate data basis for subsequently determining which filtration level of filtration component 102 to use for filtration.

[0062] In one embodiment, the water quality detection component 104 can be a single water quality sensor or a sensor array consisting of multiple water quality sensors. For example, it can be a TDS probe or other sensors.

[0063] In one embodiment, a water quality detection component 104 can be installed at the water inlet of each stage of the filtration components in the water purification device.

[0064] For example, the controller in the water purification equipment is communicatively connected to the water quality detection component 104 and the valve component 103 respectively. In actual use, the controller can receive the digital signal sent by the water quality detection component 104 to obtain the water quality information of the raw water. Then, based on the water quality status reflected by the water quality information, it determines at least one target filter component from each filter component 102, determines the valve adjustment parameters of each valve component 103 based on the target filter component, and controls each valve component 103 to adjust the water flow direction according to the valve adjustment parameters, and uses the target filter component to filter the raw water.

[0065] In the above embodiment, a multi-stage filtration assembly is connected between the inlet and outlet of the water purification equipment. The filtration level of each filtration assembly increases sequentially from the inlet to the outlet. Each filtration assembly is connected to the subsequent filtration assemblies through a pipeline. Multiple valve assemblies are provided for the connection management of each filtration assembly. By controlling the opening direction of each valve assembly, the water flow direction of the water purification equipment can be adjusted, thereby realizing the on-demand reconstruction of the water flow path. A water quality detection component is also installed between the first-stage filtration component and the inlet to detect the water quality information of the raw water. The controller can determine the target filtration component that matches the water quality status based on the water quality information. Then, it controls the valve components to adjust the water flow direction and uses the target filtration component to filter the raw water. By reconstructing the water flow path as needed, the controller can dynamically adapt to the water quality status of the raw water. For example, it can guide raw water with better quality to bypass the downstream filtration components to complete the filtration, thus extending the service life of the downstream filtration components. For raw water with poor quality, it can construct a multi-stage filtration path including the downstream filtration components for filtration. While ensuring the quality of the output water, it can effectively improve the service life of the purification equipment and reduce the equipment operating costs.

[0066] When water purification equipment is running, in addition to the quality of the raw water, the water flow rate is also a key factor affecting the purification effect. For example, if the raw water quality is poor and the flow rate is too fast, the water flow will not have enough contact time with the filter element, and there is a risk that the pollutants will not have enough time to be fully adsorbed or intercepted. They may directly penetrate the filter element, resulting in the concentration of pollutants in the water exceeding the standard.

[0067] Based on this, in one embodiment, such as Figure 2 As shown, the water purification equipment may also include a flow adjustment component 201 disposed between the first-stage filtration component and the water inlet. The flow adjustment component 201 is communicatively connected to the controller and is used to adjust the flow rate of the raw water entering the first-stage filtration component.

[0068] The flow adjustment component 201 is a device component capable of changing the volume of fluid passing through the inlet per unit time. For example, the flow adjustment component 201 may include at least one of a flow adjustment valve or a water pump. The flow adjustment valve can control the flow rate of raw water passing through it per unit time by changing its opening degree; for example, the valve opening degree may include fully open, half open, or 1 / 3 open. The water pump can adjust its speed by changing the motor power supply frequency, thereby controlling the flow rate of raw water passing through the inlet and entering the first-stage filtration component per unit time; for example, the water pump power may be 100%, 50%, or 20% of its rated power.

[0069] Understandably, when the diameter of the inlet is fixed, adjusting the raw water flow rate is equivalent to adjusting the raw water velocity.

[0070] The first-stage filtration component refers to the filtration component with the lowest filtration level among the multi-stage filtration components, which is mainly used to intercept large-diameter suspended solids in the raw water.

[0071] For example, the controller can determine a target water flow velocity that matches the water quality status reflected in the water quality information. The target water flow velocity is positively correlated with the water quality status; that is, the better the water quality, the lower the risk of insufficient pollutant adsorption even with rapid flow, thus requiring a faster target water flow velocity. Conversely, the worse the water quality, the less contact time between the water flow and the filter element, resulting in insufficient adsorption or interception of pollutants and poor filtration; therefore, requiring a slower target water flow velocity. After determining the target water flow velocity, the controller can determine the target flow adjustment parameters for the flow adjustment component 201 based on the correlation between the water flow velocity and the water flow rate, and then control the flow adjustment component 201 to operate according to the target flow adjustment parameters.

[0072] In one embodiment, the controller has a pre-set mapping relationship between water flow velocity and water flow rate. After the target water flow velocity is determined, the mapping relationship can be directly looked up based on the target water flow velocity to determine the target water flow rate corresponding to the target water flow velocity. Then, the target flow rate adjustment parameter of the flow rate adjustment component is determined based on the target water flow rate.

[0073] In the above embodiments, by setting a flow adjustment component, the raw water flow rate can be dynamically adjusted according to the water quality test results, thereby adjusting the raw water flow velocity. When the raw water quality is poor, the flow velocity is reduced to prolong the contact time between the water and the filter medium, which can improve the impurity interception efficiency. When the raw water quality is good, the flow velocity is increased to reduce unnecessary flow resistance, achieving synergistic optimization of filtration efficiency and operating costs.

[0074] Because water purification equipment can be installed in different scenarios, even with a fixed inlet diameter, the initial flow rate of raw water entering the equipment may vary. For example, different water pressures in different scenarios will result in different flow rates. Therefore, to improve the accuracy of raw water flow rate adjustment, in one embodiment, such as... Figure 3 As shown, the water purification equipment may also include a flow detection component 301 disposed between the first-stage filter component and the water inlet. The flow detection component 301 is communicatively connected to the controller and is used to detect the flow rate of the raw water flowing into the water inlet.

[0075] Among them, the flow detection component 301 is a device component used to detect the flow rate of raw water flowing into the inlet. When the raw water flows through the flow detection component 301, the sensing element inside the flow detection component 301 can convert the kinetic energy or pressure difference of the water flow into a pulse signal, analog voltage or digital signal. The characteristic parameters of the signal have a deterministic correspondence with the volume of water passing through the cross section per unit time, thereby realizing the real-time measurement of the water flow rate at that location.

[0076] In one embodiment, the flow detection component 301 may be a flow sensor, such as a flow meter.

[0077] In one embodiment, a flow detection component 301 can be installed at the water inlet of each stage of the filtration components in the water purification device.

[0078] For example, the controller can obtain the diameter of the device inlet, determine the target flow rate matching the target water flow velocity based on the diameter, and accurately obtain the initial flow rate of the raw water through the flow detection component 301. Based on the target flow rate and the initial flow rate, the controller determines the target flow rate adjustment parameters.

[0079] In the above embodiments, by setting a flow detection component, the initial flow rate of the raw water can be accurately detected. After determining the target flow rate based on the inlet diameter and the target flow velocity, the target flow rate adjustment parameter can be determined based on the deviation between the measured initial flow rate and the target flow rate. By controlling the flow adjustment component to operate according to the target flow rate adjustment parameter, the actual flow rate can be adjusted to the target value, thereby achieving precise closed-loop control of the water flow velocity. This ensures that the actual flow velocity can always stably match the target flow rate under dynamic flow rate changes, effectively improving the filtration efficiency and controllability of the purification equipment.

[0080] Based on the same inventive concept, in one embodiment, such as Figure 4 As shown, a water purification equipment control method is provided. Taking the application of this method to the controller of a water purification equipment as an example, the method includes the following steps:

[0081] S402, Obtain water quality information of the raw water flowing into the water purification equipment.

[0082] Raw water refers to untreated water that has not been filtered by a water purification system and is introduced from an external water source. The quality of raw water can vary depending on the environment.

[0083] The raw water quality information is collected by a water quality detection component installed at the inlet of the water purification equipment, and is used to characterize the raw water quality. This water quality information includes, but is not limited to, single or multiple numerical parameters such as total dissolved solids (TDS), turbidity (NTU), residual chlorine concentration, and pH value.

[0084] For example, a water quality detection component installed at the inlet of the water purification equipment will detect the water quality of the raw water flowing through it and transmit the detection signal to the controller. The controller can receive the detection signal and determine the water quality information of the raw water flowing into the water purification equipment.

[0085] S404, Based on the water quality status reflected by the water quality information, at least one target filter component is determined from the filter components in the water purification equipment.

[0086] Water quality status is a classification result that reduces water quality information to discrete levels. It can be a qualitative classification label obtained by comprehensively evaluating one or more values ​​in the water quality information, used to characterize the range of pollution level of the current raw water. For example, when the TDS of the raw water is greater than or equal to 400, the water quality status of the raw water can be judged as "poor"; when the TDS of the raw water is less than 400 but greater than or equal to 200, the water quality status of the raw water can be judged as "moderate".

[0087] In this water purification system, the filtration levels of each filter component increase sequentially from the inlet to the outlet, and each filter component is connected to subsequent filter components via piping. The target filter component is selected from all filter components based on the current water quality of the raw water. It can be a single target filter component or multiple target filter components. For example, in cases of poor water quality, all filter components can be designated as target filter components; conversely, in cases of excellent water quality, only the first-stage filter component may be used as the target filter component.

[0088] For example, after obtaining the water quality information of the raw water, the controller can determine at least one target filter component from the filter components in the water purification equipment based on the water quality status reflected by the water quality information.

[0089] In one embodiment, the controller can pre-set a mapping relationship between water quality status and each filter component. After determining the water quality status of the raw water, the controller can look up the mapping relationship between the water quality status and each filter component, and determine at least one target filter component that matches the water quality status from among the filter components.

[0090] S406, Determine the valve adjustment parameters of each valve component in the water purification equipment based on the target filter component.

[0091] Each valve assembly is installed on the connecting pipe of each filter assembly and is used to adjust the direction of water flow.

[0092] Valve adjustment parameters are the driving parameters required to switch the valve assembly from its current state to a target state. To connect the water flow path corresponding to the target filter assembly, the controller needs to determine the target state that each valve assembly needs to achieve, and then determine the corresponding valve adjustment parameters based on the target state. For example, the valve core may be rotated 90°, 45°, or left unadjusted.

[0093] For example, the controller can determine the water flow path through the target filter component based on the target filter component, and then determine the target state that each valve component needs to achieve based on the water flow path. For each valve component, the controller can determine the valve adjustment parameters corresponding to the valve component based on the target state of the valve component.

[0094] S408 controls each valve assembly to adjust the water flow direction according to the adjustment parameters of each valve, and uses the target filter assembly to filter the raw water.

[0095] Adjusting the water flow direction refers to changing the valve state of the valve assembly to make the water flow through different paths in the pipeline network of the water purification equipment. After receiving the drive command sent by the controller, each valve assembly can respond to the drive command and control its internal motor or electromagnet to drive the valve core to move to the specified position, thereby changing the passage combination at each pipeline connection point, so that the water flow switches from the current path to the target path flowing through the target filter assembly.

[0096] For example, the controller can generate drive commands according to the adjustment parameters of each valve, and control each valve component to adjust the valve state through the drive commands, thereby adjusting the water flow direction so that the raw water flows through the target filter component for filtration.

[0097] In the aforementioned water purification equipment control method, raw water quality information is obtained through water quality detection and mapped to a water quality state. Then, based on this state, a matching target filter component is selected from a multi-stage filtration system. Furthermore, by calculating and adjusting the parameters of each valve, the water flow path is switched, ensuring that the raw water only flows through the specific filtration stage required for the current water quality. Therefore, when the raw water quality is good, the subsequent high-precision filter cartridge can be bypassed to reduce unnecessary consumption; when the water quality is poor, the entire process can be activated to ensure safe effluent. This achieves differentiated utilization of filter cartridge lifespan and on-demand allocation of purification resources, effectively improving the service life of the purification equipment and reducing equipment operating costs.

[0098] In one embodiment, the water quality information includes the total dissolved solids (TDS) value. S404, based on the water quality status reflected in the water quality information, determining at least one target filtration component from among the filtration components in the water purification device includes: comparing the TDS value with each candidate water quality range to determine the target water quality range to which the raw water's water quality status belongs. From among the filtration components, the filtration component that matches the target water quality range is determined as the target filtration component.

[0099] Total dissolved solids (TDS) is a quantitative indicator of the total mass concentration of dissolved inorganic salts and some organic matter in water. It represents the total mass of all dissolved solids per unit volume of water, expressed in milligrams per liter (mg / L) or parts per million (ppm). This value is obtained by measuring the conductivity of a water sample and converting it using temperature compensation. It reflects the total content of dissolved salts in the water, such as the total content of carbonates, chlorides, and sulfates of calcium, magnesium, sodium, and potassium.

[0100] In this context, a candidate water quality interval is a discrete sub-interval formed by dividing the continuously distributed total dissolved solids (TDS) value range according to its numerical range. Each candidate water quality interval corresponds to a different water quality state. Understandably, designers pre-set multiple TDS thresholds and divide the water quality into multiple candidate intervals based on these thresholds. Taking three TDS thresholds A, B, and C as an example, candidate water quality intervals can include ≥A, A~B, B~C, and <C. Here, A~B means the TDS value is greater than or equal to B and less than A. B~C means the TDS value is greater than or equal to C and less than B, and so on. Different candidate water quality intervals correspond to different water quality states. For example, if the candidate water quality interval is ≥A, the corresponding water quality state is poor. If the candidate water quality interval is A~B, the corresponding water quality state is moderate. If the candidate water quality interval is B~C, the corresponding water quality state is good. If the candidate water quality interval is <C, the corresponding water quality state is very good.

[0101] For example, after obtaining the total dissolved solids value of the raw water, the controller can compare the candidate water quality intervals of the total dissolved solids value range to determine the target water quality interval to which the raw water quality state belongs, and determine the filter component that matches the target water quality interval from among the filter components as the target filter component.

[0102] In one embodiment, the controller is pre-set with matching relationships between each candidate water quality range and each filter component. After determining the target water quality range to which the raw water quality state belongs, the controller can find matching relationships based on the target water quality range and determine the filter component that matches the target water quality range as the target filter component.

[0103] In the above embodiments, by discretizing the continuously changing total dissolved solids value into several candidate water quality intervals and screening the corresponding filter components by interval matching, the decision basis for the purification path is improved from a single numerical threshold to interval-level judgment. This can eliminate frequent path switching caused by measurement fluctuations near a single threshold. Furthermore, the combination of different filtration levels corresponding to different water quality intervals can ensure that the purification accuracy is strictly matched with the influent water quality, thereby achieving refined utilization of filter cartridge resources.

[0104] In one embodiment, such as Figure 5 As shown, the water purification equipment control method may also include the following steps:

[0105] S502, based on the water quality status reflected in the water quality information, determine the target water flow velocity that matches the water quality status.

[0106] The target flow velocity is the desired flow rate of raw water with its current quality within the water purification equipment. The target flow velocity is positively correlated with water quality; better water quality means a lower risk of insufficient pollutant adsorption even with rapid flow, thus requiring a faster target flow velocity. Conversely, poorer water quality means insufficient contact time between the water and the filter element, resulting in inadequate adsorption or interception of pollutants and poor filtration; therefore, a slower target flow velocity is required.

[0107] For example, the controller can determine a target water flow velocity that matches the water quality status based on the water quality information.

[0108] In one embodiment, the controller is pre-set with a mapping relationship between various water quality states and water flow velocities. After the water quality state is determined, the mapping relationship can be found using the water quality state to determine the target water flow velocity that matches the water quality state.

[0109] In one embodiment, the controller is pre-configured with a flow rate determination function for each water quality state. After determining the raw water quality state, the controller can calculate the target flow velocity matching the water quality state based on the flow rate determination function corresponding to that state. It is understood that the flow rate determination function can be a function set by the designer based on experiments or experience. For example, in the case of poor water quality, the corresponding flow rate determination function could be V_water = (TA) / A + 200 (mL / s). In the case of moderate water quality, the corresponding flow rate determination function could be V_water = (TB) / B + 250 (mL / s).

[0110] S504, determine the target flow adjustment parameters of the flow adjustment component in the water purification equipment based on the target water flow velocity.

[0111] The flow adjustment component is used to adjust the flow rate of raw water entering the first-stage filtration component. The target flow adjustment parameter is the driving parameter required for the flow adjustment component to switch from its current state to the target state.

[0112] For example, the controller can determine the target flow adjustment parameters of the flow adjustment component in the water purification equipment based on the target water flow velocity. For example, the target flow adjustment parameters may include adjusting the valve opening to be fully open, or adjusting the power of the water pump to 50% of its rated power, etc.

[0113] In one embodiment, the controller has a pre-set mapping relationship between water flow velocity and water flow rate. After the target water flow velocity is determined, the mapping relationship can be directly looked up based on the target water flow velocity to determine the target water flow rate corresponding to the target water flow velocity. Then, the target flow rate adjustment parameter of the flow rate adjustment component is determined based on the target water flow rate.

[0114] S506 controls the operation of the flow adjustment component according to the target flow adjustment parameters.

[0115] For example, after obtaining the target flow adjustment parameters of the flow adjustment component in the water purification equipment, the controller can control the flow adjustment component to operate according to the target flow adjustment parameters.

[0116] In the above embodiments, by establishing a positive correlation between water quality status and target water flow velocity, the controller reduces the flow velocity as water quality deteriorates, thereby extending the contact time between a unit volume of water and the filter medium, increasing the retention probability and adsorption sufficiency, and thus improving the filtration reliability of the water purification equipment. Conversely, increasing the flow velocity as water quality improves can effectively shorten the flow time, reduce pumping energy consumption, and increase the water production rate per unit time, thereby achieving a synergistic optimization of purification effect and operating efficiency.

[0117] In one embodiment, S504, determining the target flow adjustment parameter of the flow adjustment component in the water purification device based on the target water flow velocity includes: determining a target flow rate matching the target water flow velocity based on the inlet diameter of the water purification device; obtaining the initial flow rate of the raw water; and determining the target flow adjustment parameter based on the target flow rate and the initial flow rate.

[0118] Among them, the inlet diameter is the internal geometric scalar of the pipe flow cross-section inside the inlet, and the inlet diameter determines the maximum communication capacity of the water flow at that cross-section. It is the fundamental geometric parameter for calculating the conversion relationship between flow rate and flow velocity.

[0119] The target flow rate is the desired volumetric flux required to achieve the target water flow velocity. The initial flow rate is the actual volumetric flux of raw water flowing into the purification equipment without flow adjustment.

[0120] For example, the controller can obtain the diameter of the inlet in the water purification device, determine the cross-sectional area of ​​the inlet based on the diameter, and then calculate the product of the cross-sectional area and the target water flow velocity to obtain the target flow rate matching the target water flow velocity. At the same time, the controller can detect the initial flow rate of the raw water through the flow detection component, and determine the target flow adjustment parameters required to finally drive the flow adjustment component to operate based on the difference between the target flow rate and the initial flow rate.

[0121] In one embodiment, the controller can use a PID algorithm to determine the target flow adjustment parameters required to drive the flow adjustment component to operate based on the difference between the target flow and the initial flow.

[0122] In the above embodiments, by obtaining the actual diameter of the water purification equipment itself as a geometric reference, the target water flow velocity is accurately converted into the corresponding target flow rate, and the measured value of the initial flow rate is introduced to form a closed-loop feedback. The controller calculates the adjustment parameters by comparing the deviation between the target flow rate and the initial flow rate, so that the flow adjustment component can calibrate the actual flow rate to the target value. This can effectively reduce the flow deviation caused by factors such as upstream water pressure fluctuations, differences in pipeline resistance, and manufacturing tolerances of the diameter, so that the actual water flow velocity accurately converges to the target value, thereby improving the filtration reliability of the water purification equipment.

[0123] In one embodiment, such as Figure 6 As shown, a water purification device for use in an ice maker is provided, wherein the water purification device may include three filtration units, namely a first-stage filtration unit 601, a second-stage filtration unit 602 and a third-stage filtration unit 603.

[0124] Each stage of the filtration unit can consist of a filter element 604, an inlet end 605, an outlet end 606, a water quality sensor 607, and a flow sensor 608.

[0125] Among them, filter element 604 is a device that filters water and is the core component of the filtration system. It removes impurities, particulate matter, odors, bacteria or harmful substances from the fluid through physical interception, adsorption or chemical reaction, thereby purifying the fluid.

[0126] The inlet 605 and outlet 606 can be constructed using pipes, connectors, and interfaces. The inlet 605 of the first-stage filtration unit is connected at one end to the filter element 604 via a pipe, and at the other end to either tap water or water pumped into the internal water tank—the water source. The outlet 606 of the final-stage filtration unit needs to be connected to a faucet or outlet to supply water to the user.

[0127] The water quality sensor 607 is a sensor that can detect the concentration of impurities in the water, such as a TDS probe or other sensors. Each filter unit has a corresponding water quality sensor 607 installed at its inlet 605.

[0128] The flow sensor 608 is a sensor that can detect the flow rate of liquid, such as a flow meter. Each filter unit has a corresponding flow sensor 608 installed at its inlet 605.

[0129] The water purification equipment has a water pump 609 installed before the water inlet 605 of the first-stage filtration unit. The water pump 609 is used to control the water flow rate. For example, the water flow rate can be controlled by adjusting the operating power of the water pump. It is understood that the water pump can be an electric motor pump.

[0130] Each stage of the filtration system is connected end-to-end via piping. However, the first-stage filtration unit 601 is also connected to the third-stage filtration unit 603 via piping. This means that each preceding filtration unit is connected to all subsequent filtration units via piping. At each branch point of the piping, there is a valve that controls the water flow direction. Specifically, there is a first valve 610 located between the first-stage and second-stage filtration units 601 and 602, a second valve 611 located between the second-stage and third-stage filtration units 602 and 603, a third valve 612 located between the third-stage filtration unit 603 and the outlet, and a fourth valve 613 located between the first-stage and third-stage filtration units 601 and 603. These valves can be anything such as solenoid valves, as long as they control the water flow direction.

[0131] Each stage of the filtration system has a different function. The earlier stages primarily filter large particles, while the later stages focus on filtering finer impurities and adsorbing odors and harmful gases from the water. For example, the filter element of the first-stage filtration unit 601 can be made of PP meltblown cotton, which uses the capillary action of the fibers and mechanical interception to remove large particles such as sediment and rust. The filter element of the second-stage filtration unit 602 can be made of activated carbon (granular or compressed carbon rods), which is mainly used to adsorb residual chlorine, discoloration, and odors in the water, as well as harmful gases such as formaldehyde and benzene in the air. The filter element of the third-stage filtration unit 603 can be made of RO reverse osmosis membrane, which can remove heavy metals, viruses, and scale, producing pure water.

[0132] To maximize the lifespan of the filter cartridges in the filtration unit and obtain the best water quality, different purification processes need to be adopted for different influent water qualities, namely, using different water purification paths, water flow paths, and water flow rates. Among them, the water flow rate can be controlled by the power control of the water pump 609. For example, the power of the water pump 609 can be controlled to 100%, 50%, 20% of its rated power, etc., to control the flow rate of water in the internal pipeline.

[0133] Wherein, the control of the water purification path is essentially the control of water flow direction, which can be realized by starting the water pump 609 and controlling the opening and closing of valves. By intercepting water flow and preventing it from entering a certain filter unit, the purpose of making water with different inlet water qualities follow different paths can be achieved.

[0134] In actual use, as Figure 7 shows, the control method for a water purification device may comprise the following steps:

[0135] First, the controller needs to delimit water quality intervals and detect the water quality at the water inlet end in real time. Illustratively, the controller may use the water quality sensor 607 to continuously collect the TDS value at the water inlet end. It can be understood that the higher the TDS value, the worse the water quality. The controller records this value as T, for example, when TDS=350, it is recorded as T=350. Fixed TDS values are set in the system, such as values A, B and C, where A>B>C, and different intervals are set, such as intervals of ≥A, A~B, B~C, <C, etc. Wherein, A~B means that the value is ≥B and <A, B~C means that the value is ≥C and <B, and so on. For example: set A=400, B=200, C=50. Detect which interval the real-time T value falls into, and enter the filtering procedure corresponding to the interval. Different intervals correspond to different filtering procedures. For example, when T=350, T falls into the interval A~B.

[0136] Subsequently, the controller needs to set filtering procedures for different intervals. Since different water qualities require different water flow rates and filtering paths, different procedures can be set to correspond to different inlet water qualities. For example: when the inlet water quality is ≥A, proceed to Procedure 1; when the inlet water quality is between A and B, proceed to Procedure 2; when the inlet water quality is between B and C, proceed to Procedure 3; when the inlet water quality is <C, proceed to Procedure 4. Different procedures have different flow rate formulas, which respectively control the opening status of valves 610 on different pipelines and the pumping power of the water pump 609, so that the water flow rate and filtering path of water with different qualities entering the filtering system can be controlled.

[0137] Procedure 1, Procedure 2, Procedure 3 and Procedure 4 will be specifically described below:

[0138] Wherein, Procedure 1 corresponds to the water quality interval T≥A, indicating that the raw water quality is poor at this time. As Figure 8 shows, the controller can use the water pump 609 to adjust the opening size to control the water flow speed, so that vwater=(T-A) / A+200 (mL / s), and control the first valve 610, the second valve 611 and the third valve 612 to adjust the valve opening direction, so that the channels below the first valve 610, the second valve 611 and the third valve 612 are closed, thus the raw water can pass through as Figure 8The water flow direction indicated by the dashed line is filtered through the first-stage filtration unit 601, the second-stage filtration unit 602, and the third-stage filtration unit 603. This ensures that the water flows into the three filtration units and completes the filtration in sequence. The flow rate is slow, impurities are fully absorbed, and the filter element is not damaged or clogged, thus extending the filter element's lifespan.

[0139] In this case, the water quality range corresponding to Program 2 is A>T≥B, indicating that the raw water quality is moderate at this time. Figure 9 As shown, the controller can control the water flow rate by adjusting the opening size of the water pump 609, ensuring that v_water = (TB) / B + 250 (mL / s). It also controls the opening directions of the first valve 610, second valve 611, third valve 612, and fourth valve 613, closing the channel to the right of the first valve 610, the channel to the left of the second valve 611, the channel to the right of the fourth valve 613, and the channel below the third valve 612. This allows raw water to flow through... Figure 9 The water flow direction indicated by the dashed line is filtered through the first-stage filtration unit 601 and the third-stage filtration unit 603. This ensures that the water flow only enters two filtration units, completing the filtration sequentially. The flow rate is moderate, and impurities are fully absorbed without wasting resources. The water can be filtered cleanly without the need for a second-stage filter element, greatly extending the filter element's lifespan.

[0140] In this case, the water quality range corresponding to program 3 is B>T≥C, indicating that the raw water quality is relatively good at this time. Figure 10 As shown, the controller can control the water flow rate by adjusting the opening size of the water pump 609, making v_water = (TC) / C + 300 (mL / s). It also controls the opening direction of the first valve 610, the second valve 611, the third valve 612, and the fourth valve 613, closing the channel below the first valve 610, the channel to the right of the second valve 611, the channel to the left of the third valve 612, and the channel to the left of the fourth valve 613. This allows the raw water to flow through... Figure 10 The water flow direction indicated by the dashed line is filtered through the first-stage filtration unit 601 and the second-stage filtration unit 602, without passing through the third-stage filtration unit 603. This ensures that the water flow only enters two filtration units and completes the filtration in sequence. The flow rate is moderate to fast, so impurities are fully absorbed without wasting resources. The water can be filtered cleanly without the need for a third-stage filter element, which greatly extends the life of the filter element.

[0141] In this case, the water quality interval corresponding to program 4 is T < C, indicating that the raw water quality is very good at this time. Figure 11As shown, the controller can control the water flow rate by adjusting the opening size of the water pump 609, ensuring that v_water = 400 (mL / s). It also controls the opening direction of the first valve 610, the second valve 611, the third valve 612, and the fourth valve 613, closing the channel to the right of the first valve 610, all channels controlled by the second valve 611, and the channel to the left of the third valve 612. This allows the raw water to flow through... Figure 11 The water flow direction indicated by the dotted line means that the water only passes through the first-stage filter unit 601 for filtration, without passing through the second-stage filter unit 602 and the third-stage filter unit 603. This ensures that the water only enters one filter unit and the flow rate is relatively fast. Because the water quality is relatively good, even if it passes through the first-stage filter element, the internal impurities can be fully absorbed, without wasting resources. The water can be filtered clean without the need for the second and third-stage filter elements, which greatly extends the life of the filter element.

[0142] The above-mentioned water purification equipment control method can balance water quality and extend filter life by real-time detection of influent water quality, such as TDS value (T), setting different programs, and dynamically adjusting water flow speed and filtration path by controlling pumps and valves at different locations in the water circuit.
