[0002] With the development of people's industrial level, the requirements for quality of life are getting higher and higher. At present, due to the increasingly serious water quality problems and the gradual improvement of people's living standards, water purifiers have gradually become one of the important household appliances in life. Water purifiers can filter and purify raw water such as tap water or bottled water, remove various impurities in the water to obtain pure water, and then output pure water for users to use by opening and closing the faucet.

[0003] In addition to being controlled by the user, the faucet can also be controlled by the water purifier itself, which increases convenience. Traditional water purifiers generally use high-pressure switch valves or electronically controlled faucets to control the working state of the water purifier.

[0065] The water purification equipment control method provided in the embodiment of the present application can be applied to Figure 1 In the water purification equipment shown. Figure 1As shown, the present application provides a water purification device, including a flow sensor 102, a water flow driving device 104, a water purification pipeline 106, a water tap 108 and a controller 110. The water flow driving device 104 and the flow sensor 102 are both arranged in the water purification pipeline 106, and the water tap 108 is arranged at one end of the water purification pipeline 106 close to the water outlet. The flow sensor 102, the water flow driving device 104 and the water tap 108 are all connected to the controller 110. The flow sensor 102 collects the water purification flow parameter of the water purification pipeline 106 and sends it to the controller 110. The controller 110 is used to control the water flow driving device 104 and the water tap 108 based on the water purification device control method recorded in each embodiment of the present application.

[0066] Among them, the flow sensor 102 is arranged in the water purification pipeline 106, and can detect the water flow in the water purification pipeline 106. When the water purification equipment uses different models of water taps 108, the water flow detected is different. When the water tap 108 is in different working states, such as different gears, the water flow detected is also different. When the water flow drive device 104 is in different working states, the water flow detected is also different, wherein the working state of the water flow drive device 104 can correspond to the working state of the water tap 108. The water flow drive device 104 can be a device such as a water pump that can drive the water in the water purification pipeline 106. The controller 110 is connected to the water flow drive device 104 and can control the start and stop and working state of the water flow drive device 104. Further, the controller 110 is connected to the water tap 108 and can control the start and stop and working state of the water tap 108.

[0067] During the operation of the water purification equipment, the controller 110 controls the water flow driving device 104 to drive the water in the water purification pipeline 106 based on the needs corresponding to the instructions issued by the user, and simultaneously controls the water tap 108 to open and the flow sensor 102 to start working, so that water flows to the water outlet of the water purification pipeline 106 and flows out from the water tap 108 for the user to drink.

[0068] Furthermore, the water purification pipeline 106 can filter and purify water, so that the raw water flowing into the water inlet of the water purification pipeline 106 is purified, and pure water (also called purified water) flows out from the water outlet of the water purification pipeline 106 through the water tap 108. In an exemplary embodiment, the water purification pipeline 106 includes a first filter device and a second filter device. The first filter device can be a composite filter element, and the composite filter element can be provided with a multi-layer filter element, which can filter water repeatedly; the second filter device can be an RO (Reverse Osmosis) membrane filter element, and the RO membrane filter element can separate the solvent and solute in the solution under pressure, that is, separate the impurities in the water for purification. The first filter device and the second filter device are connected in sequence and arranged at different positions of the water purification pipeline 106 to filter the water flowing through in sequence.

[0069] Specifically, the pipeline in the water purification pipeline 106 connects the first filter device and the second filter device, and the raw water at the water inlet can be purified by the first filter device and the second filter device in sequence, and then output through the water tap 108. Optionally, the first filter device may include a pre-filter element and a post-filter element, and the raw water at the water inlet first flows through the pre-filter element of the first filter device for a first filtration, then flows through the second filter device for a second filtration, and then returns to the post-filter element of the first filter device for a third filtration, and then output to the water tap 108.

[0070] Furthermore, a solenoid valve is also provided on the clean water pipeline 106, which can control the on-off of the pipeline at the set position, for example, a water inlet solenoid valve is provided on the pipeline between the pre-filter element of the first filter device and the second filter device. A check valve can also be provided on the clean water pipeline 106 to prevent the water from flowing in reverse, and the check valve can be provided between the second filter device and the water tap 108. Optionally, the flow sensor 102 can be provided on the pipeline between the second filter device and the post-filter element of the first filter device, and the water flow driving device 104 can be provided on the pipeline between the pre-filter element of the first filter device and the second filter device.

[0071] Exemplarily, the water flow driving device 104 may be a pressure-stabilizing pump, the flow sensor 102 may be a flow meter, and the water tap 108 may be an electrically controlled tap.

[0072] In an exemplary embodiment, Figure 2 As shown, a water purification equipment control method is provided, and the method is applied to Figure 1 The controller 110 in FIG. 1 is taken as an example to illustrate the method, which includes the following steps 202 to 206. Among them:

[0073] Step 202, obtaining the water purification flow parameters of the water purification equipment.

[0074] The water purification device includes a flow sensor, which is arranged in the water purification pipeline of the water purification device and can monitor the amount of purified water output by the water purification pipeline. When the water purification device is started and water is discharged, it is equivalent to that the water purification device is in a working state. At this time, water flows out of the water faucet of the water purification device. The flow sensor can detect the water flow in the water purification pipeline and transmit it to the controller so that the controller can obtain the purified water flow parameters.

[0075] The clean water flow parameter can characterize the clean water volume output by the water inlet equipment. Optionally, when the flow sensor does not reset the count each time, the data detected may include historical clean water volume and other data. The controller analyzes the historical clean water volume in combination with the start and stop of the water purification equipment and the control log of the water purification equipment at historical moments to obtain the clean water flow parameter of the water purification equipment being started this time.

[0076] Step 204, determining the pipeline delay duration based on the clean water flow parameter.

[0077] Specifically, the controller can determine the pipeline delay time based on the clean water flow parameter and the software processing logic in the controller. For example, different delay gears are divided according to the size of the clean water flow parameter, and each delay gear corresponds to a different pipeline delay time. After obtaining the clean water flow parameter, the controller determines the delay gear corresponding to the clean water flow parameter and determines the pipeline delay time accordingly.

[0078] The pipeline delay time takes into account the water flow in the pipeline between the water flow driving device and the water tap in the water purification pipeline of the water purification equipment. The size of the water flow and the water pressure are likely to impact the water tap when the water purification equipment stops supplying water, causing the water tap to shake and be damaged. Therefore, a pipeline delay time is calculated based on the size of the water flow, so as to reduce the impact on the water tap when the water purification equipment stops supplying water, and achieve smooth and reliable water stop control.

[0079] In an exemplary embodiment, the controller may also determine the pipeline delay time based on the clean water flow parameter in other ways, such as Figure 3 As shown, step 204 includes step 302: based on the clean water flow parameter and the preset delay parameter, calculating and determining the pipeline delay time.

[0080] Specifically, the controller stores a preset delay parameter, which is a set value used to calculate the pipeline delay time. After obtaining the clean water flow parameter, the controller will combine the clean water flow parameter and the preset delay parameter to calculate the pipeline delay time. The preset delay parameter can be a constant or a function. By combining the clean water flow parameter for calculation, the accurate pipeline delay time is obtained.

[0081] Exemplarily, the preset delay parameter is a one-dimensional linear function, whose independent variable is the clean water flow parameter, and whose dependent variable is the calculated pipeline delay time. For example, the preset delay parameter is n=kQ+n0, where n is the pipeline delay time; k is a constant parameter, and k is greater than 0; Q is the clean water flow parameter; and n0 is a preset value. After obtaining the clean water flow parameter, the controller substitutes the clean water flow parameter into the function of the preset delay parameter to obtain the pipeline delay time.

[0082] Step 206, in response to the stop water intake signal, control the water flow driving device of the water purification equipment to close, and after the closing time reaches the pipeline delay time, control the water intake tap of the water purification equipment to close.

[0083] The water flow driving device is arranged on the water purification pipeline of the water purification equipment, and the water tap is arranged on one end of the water purification pipeline of the water purification equipment near the water outlet. The controller connects the water flow driving device and the water tap, and can control the start and stop and working state of the water flow driving device and the water tap. The specific connection relationship and setting method have been recorded in the previous text and will not be repeated here.

[0084] Specifically, during the water outlet process, the water purification device may trigger a stop water extraction signal in response to an operation performed by the user; or it may trigger a stop water extraction signal based on the water consumption, water use time or other set parameters recorded by the controller. In the case where the water purification device triggers a stop water extraction signal, the controller responds to the stop water extraction signal and needs to control the water extraction tap of the water purification device to stop outputting water. Since it is necessary to consider reducing the impact of the water pressure in the pipeline on the water extraction tap, the controller immediately controls the water flow drive device of the water purification device to close when responding to the stop water extraction signal, stops the water pump in the water purification pipeline, and reduces the water flow rate and water pressure in the pipeline. Then, based on the pipeline delay time calculated in the previous sequence, the pipeline delay time is delayed on the basis of the closure of the water flow drive device, that is, the water extraction tap is controlled to close when the closure time of the water flow drive device reaches the pipeline delay time.

[0085] Due to the delay, the water pressure in the water purification pipeline can be further reduced through the water tap within the delay period of the pipeline. At this time, closing the water tap will not cause too much water pressure impact on the water tap, which can alleviate the shaking of the water tap when the water purification equipment is cut off, and ensure the reliability of the use of the water purification equipment.

[0086] The above-mentioned water purification equipment control method includes obtaining the water purification flow parameters of the water purification equipment, determining the pipeline delay time based on the water purification flow parameters, controlling the water flow driving device of the water purification equipment to close in response to the stop water intake signal, and controlling the water intake tap of the water purification equipment to close after the closing time reaches the pipeline delay time. Among them, the water flow driving device is arranged in the water purification pipeline of the water purification equipment, and the water intake tap is arranged at one end of the water purification pipeline of the water purification equipment close to the water outlet. By controlling the water intake tap to close after the pipeline delay time, the water flow driving device and the water intake tap can be controlled to close at staggered times when the water purification equipment is closed, thereby reducing the pressure of the water in the water purification pipeline on the water intake tap when it is closed, thereby improving the reliability of the use of the water purification equipment.

[0087] In an exemplary embodiment, the water extraction stop signal of the water purification device may be triggered by the water extraction amount. Figure 4 As shown, the water purification equipment control method further includes steps 402 to 404. Among them, steps 402 to 404 can be performed after step 202 or after step 204, as long as they are performed before step 206.

[0088] Step 402, obtaining the set water intake volume of the water purification equipment.

[0089] Specifically, the controller stores a set water intake, which can be preset and fixed in the water purification device, or selected by the user during the current startup of the water purification device. The value of the set water intake is not limited here. In this embodiment, it is equivalent to configuring a certain set water intake each time the water purification device is started. The water purification device discharges water based on the set water intake, and the controller controls the water flow driving device and the water tap accordingly for the user to take water.

[0090] Step 404, determining whether the water purification device triggers a water intake stop signal according to the set water intake volume and water purification flow parameters.

[0091] Specifically, the controller obtains the clean water flow parameter in real time, monitors the water flow during this startup, and compares the clean water flow parameter with the set water intake, and determines whether to trigger a stop water intake signal based on the set water intake and the clean water flow parameter.

[0092] Optionally, when the water flow rate of this startup in the real-time monitored water purification flow parameters has not reached the set water intake volume, the controller can determine that the water purification equipment has not triggered the stop water intake signal at this time; when the water flow rate of this startup in the real-time monitored water purification flow parameters reaches the set water intake volume, the controller can determine that the water purification equipment has triggered the stop water intake signal at this time.

[0093] Furthermore, since the impact of the water pressure in the water purification pipeline on the water tap needs to be considered when controlling the water purification equipment, the condition for triggering the stop water intake signal can be adjusted based on the set water intake amount. Figure 5 As shown, step 404 includes steps 502 to 506 .

[0094] Step 502, calculating the pipeline reserve of the water purification pipeline of the water purification equipment based on the pipeline delay time.

[0095] Wherein, the pipeline delay duration is calculated based on step 204, and steps 402 to 404 may be performed after step 204. If steps 402 to 404 are performed after step 202 and before step 204, step 204 needs to be performed before step 502 to calculate the pipeline delay duration.

[0096] Specifically, after the controller calculates the pipeline delay time, it calculates the pipeline retention of the clean water pipeline within the pipeline delay time according to the pipeline delay time, that is, the water flow rate discharged from the tap within the pipeline delay time. The water flow rate can be obtained based on the pipeline delay time and the clean water flow rate parameter. The clean water flow rate parameter may include the clean water flow rate. On the basis of the known clean water flow rate and time (pipeline delay time), the flow rate, that is, the pipeline retention, can be calculated.

[0097] It should be noted that since the water flow drive device has been turned off during the pipeline delay period, the water flow rate during the pipeline delay period should be lower than the water flow rate when the water flow drive device is working normally. In other words, the value of the clean water flow rate obtained based on the clean water flow parameter will be slightly higher than the actual clean water flow rate during the pipeline delay period. The controller can calculate the clean water flow rate of the clean water flow parameter based on historical experience, the assistance of data models, analysis and simulation of cloud big data, or the settings of the staff, and obtain flow rate data that is closer to the actual situation to calculate the pipeline retention.

[0098] Step 504, calculating the water outage trigger parameter according to the set water intake and pipeline retention.

[0099] Specifically, the set water intake is the water flow that meets the user's needs, and it is also the water flow that the water purification equipment should actually output. In order to reduce the impact and damage of water pressure on the water tap, the controller needs to close the water flow drive device in advance while considering the pipeline retention volume, and close the water tap after the water flow of the pipeline retention volume flows out, that is, after the pipeline delay time. In this way, the water purification equipment can accurately meet the needs of users while ensuring the stability of the use of the water purification equipment. Therefore, the controller will set the water intake minus the pipeline retention volume, and the difference obtained is used as the water outage trigger parameter.

[0100] Step 506: When the purified water flow rate parameter reaches the water stop trigger parameter, a water extraction stop signal is triggered.

[0101] Specifically, after the controller calculates the water cut-off trigger parameter, it will use the water cut-off trigger parameter as the trigger value to determine whether the water extraction stop signal is triggered. The controller obtains the water purification flow parameter in real time, and when the water flow rate of this startup in the real-time monitored water purification flow parameter has not reached the water cut-off trigger parameter, the controller can determine that the water purification device has not triggered the water extraction stop signal at this time; when the water flow rate of this startup in the real-time monitored water purification flow parameter reaches the water cut-off trigger parameter, the controller can determine that the water purification device has triggered the water extraction stop signal at this time.

[0102] In this embodiment, the pipeline retention volume is calculated based on the pipeline delay duration, and the water stop trigger parameters are calculated according to the management retention volume and the set water intake volume. The trigger conditions of the water intake stop signal are adjusted, and the water stop control of the water purification equipment is performed from the perspective of flow rate, thereby improving the accuracy of the water purification equipment control.

[0103] After calculating the water stop trigger parameter based on the set water intake and pipeline retention, the conditions for triggering the water stop signal can also be adjusted from the perspective of time. Figure 6 As shown, after step 504, the water purification equipment control method further includes steps 602 to 606.

[0104] Step 602, determining the duration of this round of water extraction based on the water outage trigger parameter and the clean water flow parameter.

[0105] Specifically, while calculating the water cut-off trigger parameter, the controller also obtains the clean water flow parameter in real time. The clean water flow rate in the clean water flow parameter can be used as a reference, the flow value of the water cut-off trigger parameter can be used as the denominator, and the clean water flow rate can be used as the numerator. The time required for the flow of the water cut-off trigger parameter to be discharged at the clean water flow rate can be obtained through division operation, that is, the duration of this round of water extraction. The duration of this round of water extraction can represent the time required for the water tap to complete the output of the set water intake volume during the current startup of the water purification equipment, and the time required for the clean water volume obtained by the user to meet the user's needs.

[0106] Step 604, obtaining the startup parameters of the water purification equipment.

[0107] Specifically, the start-up and water shut-off of the water purification equipment are controlled by the controller, so the controller can obtain the start-up parameters of the water purification equipment, that is, the start-up duration of the water purification equipment. The controller can obtain the start-up parameters by recording the start-up duration of the water flow drive device, or it can obtain the start-up parameters by starting the timing when the flow sensor detects that there is water flowing in the water purification pipeline.

[0108] Furthermore, the startup parameters can be obtained based on the clean water flow parameters, for example, by calculating the clean water flow data and the clean water flow rate data in the clean water flow parameters. Then the clean water flow parameters of the water purification equipment can include the startup parameters of the water purification equipment. In this case, step 604 can be replaced by determining the startup parameters of the water purification equipment according to the clean water flow parameters.

[0109] Step 606: When the start parameter matches the duration of this round of water extraction, a signal to stop water extraction is triggered.

[0110] Specifically, after the controller obtains the start-up parameters, it will use the duration of this round of water extraction as the trigger value to determine whether the stop water extraction signal is triggered. The controller obtains the start-up parameters in real time, or calculates the start-up parameters in real time based on the water purification flow parameters. When the duration of this start-up in the real-time start-up parameters has not reached the duration of this round of water extraction, the controller can determine that the water purification device has not triggered the stop water extraction signal at this time; when the duration of this start-up in the real-time start-up parameters reaches the duration of this round of water extraction, the controller can determine that the water purification device has triggered the stop water extraction signal at this time.

[0111] In this embodiment, the duration of this round of water extraction is determined based on the water stop trigger parameter and the water purification flow parameter, and the start parameter is obtained. The start parameter is then compared with the duration of this round of water extraction, and the stop water extraction signal is triggered when the two match. By triggering the stop water extraction signal from the perspective of time, a multi-dimensional optional triggering method for the stop water extraction signal is provided, which is conducive to improving the accuracy of water purification equipment control.

[0112] In an exemplary embodiment, Figure 7 As shown, after step 202, the water purification equipment control method further includes steps 702 to 704.

[0113] Step 702, recording the startup parameters of the water purification equipment, and determining the lower limit value of the water purification flow rate based on the startup parameters.

[0114] The startup parameter of the water purification device may refer to the startup duration of the water purification device. The controller may obtain the startup parameter by recording the startup duration of the water flow driving device, or may obtain the startup parameter by starting the timing when the flow sensor detects that water flows in the water purification pipeline.

[0115] Furthermore, the startup parameter can be obtained based on the clean water flow parameter, for example, by calculating the clean water flow data and the clean water flow rate data in the clean water flow parameter. Then the clean water flow parameter of the water purification device can include the startup parameter of the water purification device. In this case, step 702 can be replaced by determining the startup parameter of the water purification device according to the clean water flow parameter, and determining the lower limit of the clean water flow based on the startup parameter.

[0116] The controller stores the lower limit of the purified water flow rate, which can be determined based on the actual structural settings of the water purification equipment, such as the water flow drive device, the diameter or length of the purified water pipeline, and has different lower limits according to different structural settings. After obtaining the startup parameters, the startup time of the water purification equipment in this startup is obtained. The controller combines the startup parameters and the stored lower limit of the purified water flow rate, and multiplies the two to obtain the lower limit of the purified water flow rate.

[0117] Step 704, comparing the purified water flow parameter with the purified water flow lower limit value to determine the working state of the flow sensor of the water purification equipment.

[0118] Specifically, the controller compares the clean water flow parameter collected by the flow sensor with the calculated lower limit of the clean water flow, and determines the working state of the flow sensor of the water purification equipment according to the comparison structure. When the clean water flow parameter is greater than or equal to the lower limit of the clean water flow, it indicates that the flow in the clean water pipeline detected by the flow sensor is within the actual possible clean water flow range, which can prove that the working state of the flow sensor is normal. When the clean water flow parameter is less than the clean water flow, it indicates that the flow in the clean water pipeline detected by the flow sensor is lower than the lowest lower limit of the clean water flow range in the clean water pipeline, which can indicate that the working state of the flow sensor is faulty.

[0119] Furthermore, when the working state of the flow sensor is faulty, but the water purification device is still starting to discharge water, it is necessary to add a minimum water stop control to the control of the water purification device to avoid abnormal water stop control of the water purification device due to abnormal working state of the flow sensor. Figure 8 As shown, after step 704, the water purification equipment control method further includes steps 802 to 804.

[0120] Step 802: When the flow sensor of the water purification device is in a faulty state, the threshold duration of this round is calculated based on the lower limit of the water purification flow rate and the set water intake of the water purification device.

[0121] Specifically, if the controller determines that the working state of the flow sensor of the water purification equipment is faulty, then the water flow in the water flow parameter obtained by the flow sensor is erroneous flow data. The controller needs to trigger the stop water intake signal from another angle based on the erroneous flow data to ensure reliable water outage control of the water purification equipment. The controller then calculates the threshold duration of this round based on the calculated lower limit of the water flow and the set water intake obtained when the water purification equipment is started. Specifically, the set water intake is divided by the lower limit of the water flow to obtain the threshold duration of this round.

[0122] Step 804: When the start parameter matches the threshold duration of this round, a signal to stop taking water is triggered.

[0123] After the controller obtains the startup parameters, if the flow sensor fails and the water extraction duration of this round is unreliable, the threshold duration of this round will be used as the trigger value to determine whether the stop water extraction signal is triggered. The controller obtains the startup parameters in real time. When the duration of this startup in the real-time startup parameters has not reached the threshold duration of this round, the controller can determine that the water purification equipment has not triggered the stop water extraction signal at this time; when the duration of this startup in the real-time startup parameters reaches the threshold duration of this round, the controller can determine that the water purification equipment has triggered the stop water extraction signal at this time.

[0124] In this embodiment, by detecting the working state of the flow sensor of the water purification equipment, and being able to calculate the threshold duration of this round based on the set water intake and the lower limit of the water purification flow when the working state of the flow sensor is faulty, the threshold duration of this round is used as the trigger condition for the stop water intake signal when the flow sensor fails. The flow sensor can be detected, and the water stop control of the water purification equipment can be ensured to be effective and reliable when the flow sensor fails, avoiding the waste of a large amount of water resources due to water stop failure, thereby improving the reliability of the use of the water purification equipment.

[0125] Based on the same technical concept, the present application also provides a water purification device, such as Figure 1 As shown, the present application provides a water purification device, including a flow sensor 102, a water flow driving device 104, a water purification pipeline 106, a water tap 108 and a controller 110. The water flow driving device 104 and the flow sensor 102 are both arranged in the water purification pipeline 106, and the water tap 108 is arranged at one end of the water purification pipeline 106 close to the water outlet. The flow sensor 102, the water flow driving device 104 and the water tap 108 are all connected to the controller 110. The flow sensor 102 collects the water purification flow parameter of the water purification pipeline 106 and sends it to the controller 110. The controller 110 is used to control the water flow driving device 104 and the water tap 108 based on the water purification device control method recorded in each embodiment of the present application.

[0126] Among them, the flow sensor 102 is arranged in the water purification pipeline 106, and can detect the water flow in the water purification pipeline 106. When the water purification equipment uses different models of water taps 108, the water flow detected is different. When the water tap 108 is in different working states, such as different gears, the water flow detected is also different. When the water flow drive device 104 is in different working states, the water flow detected is also different, wherein the working state of the water flow drive device 104 can correspond to the working state of the water tap 108. The water flow drive device 104 can be a device such as a water pump that can drive the water in the water purification pipeline 106. The controller 110 is connected to the water flow drive device 104 and can control the start and stop and working state of the water flow drive device 104. Further, the controller 110 is connected to the water tap 108 and can control the start and stop and working state of the water tap 108.

[0127] During the operation of the water purification equipment, the controller 110 controls the water flow driving device 104 to drive the water in the water purification pipeline 106 based on the needs corresponding to the instructions issued by the user, and simultaneously controls the water tap 108 to open and the flow sensor 102 to start working, so that water flows to the water outlet of the water purification pipeline 106 and flows out from the water tap 108 for the user to drink.

[0128] Furthermore, the water purification pipeline 106 can filter and purify water, so that the raw water flowing into the water inlet of the water purification pipeline 106 is purified, and pure water (also called purified water) flows out from the water outlet of the water purification pipeline 106 through the water tap 108. In an exemplary embodiment, the water purification pipeline 106 includes a first filter device and a second filter device. The first filter device can be a composite filter element, and the composite filter element can be provided with a multi-layer filter element, which can filter water repeatedly; the second filter device can be an RO (Reverse Osmosis) membrane filter element, and the RO membrane filter element can separate the solvent and solute in the solution under pressure, that is, separate the impurities in the water for purification. The first filter device and the second filter device are connected in sequence and arranged at different positions of the water purification pipeline 106 to filter the water flowing through in sequence.

[0129] Specifically, the pipeline in the water purification pipeline 106 connects the first filter device and the second filter device, and the raw water at the water inlet can be purified by the first filter device and the second filter device in sequence, and then output through the water tap 108. Optionally, the first filter device may include a pre-filter element and a post-filter element, and the raw water at the water inlet first flows through the pre-filter element of the first filter device for a first filtration, then flows through the second filter device for a second filtration, and then returns to the post-filter element of the first filter device for a third filtration, and then output to the water tap 108.

[0130] Furthermore, a solenoid valve is also provided on the clean water pipeline 106, which can control the on-off of the pipeline at the set position, for example, a water inlet solenoid valve is provided on the pipeline between the pre-filter element of the first filter device and the second filter device. A check valve can also be provided on the clean water pipeline 106 to prevent the water from flowing in reverse, and the check valve can be provided between the second filter device and the water tap 108. Optionally, the flow sensor 102 can be provided on the pipeline between the second filter device and the post-filter element of the first filter device, and the water flow driving device 104 can be provided on the pipeline between the pre-filter element of the first filter device and the second filter device.

[0131] Exemplarily, the water flow driving device 104 may be a pressure-stabilizing pump, the flow sensor 102 may be a flow meter, and the water tap 108 may be an electronically controlled tap.

[0132] Furthermore, in one embodiment, the water purification device further includes a wastewater pipeline and a wastewater solenoid valve disposed on the wastewater pipeline, the wastewater pipeline is connected to the second filter device, and is used to flush the first filter device and the second filter device and then discharge the wastewater. The wastewater solenoid valve is connected to the controller 110, and is used to adjust the opening and closing of the wastewater pipeline under the control of the controller 110.

[0133] In order to better understand the above solution, a detailed explanation is given below in conjunction with a specific embodiment.

[0134] In one embodiment, Fig. 9 As shown, the water purification equipment includes a pipeline and a composite filter element 1 (first filtering device) on the pipeline, a water inlet solenoid valve 2, a main flow meter 3, a pressure-stabilizing pump 4 (water flow driving device), an RO membrane filter element 5 (second filtering device), a water purification flow meter 6 (flow sensor), a water purification check valve 7, an electric control faucet 8 (water purification faucet), a reflux solenoid valve 9, a reflux check valve 10, a waste water solenoid valve 11 and a controller not shown in the figure. Among them, the raw water enters the pre-filter element of the composite filter element 1 through the raw water inlet, and then passes through the water inlet solenoid valve 2, the main flow meter 3, and the pressure-stabilizing pump 4 to reach the RO membrane filter element 5. At this time, the reflux solenoid valve 9 is closed, and the filtered water passes through the water purification flow meter 6 to reach the post-filter element of the composite filter element 1, and then flows through the water purification check valve 7 to reach the electric control faucet 8 to output pure water. Among them, the reflux solenoid valve 9 and the reflux check valve 10 are used to clean the RO membrane filter element 5 and discharge the waste water through the waste water solenoid valve 11.

[0135] When the controller receives the water intake signal to start the water purification equipment, it controls the water inlet solenoid valve 2, the pressure regulating pump 4, and the electric control faucet 8 to open, and the tap water (raw water) enters from the raw water inlet and is filtered in sequence through the pre-filter element of the composite filter element 1, the RO membrane filter element 5, and the post-filter element of the composite filter element 1, and then the clean water is discharged through the electric control faucet 8.

[0136] When the controller triggers the stop water extraction signal and responds, the water inlet solenoid valve 2 and the pressure regulating pump 4 are controlled to be closed instantly, and the solenoid valve in the electric faucet 8 is closed after a delay of n seconds. Preferably, the delay time n varies with the change of the clean water flow rate Q, n=kQ+n0, k is a constant, k>0, and n0 is a set value.

[0137] The water purification equipment can also realize an optimization method of quantitative water extraction. 定量 , when the water flow meter 6 reads (L 定量 -L0), the water purification equipment is controlled to stop water production as in the above steps. Among them, the preset value L0 is the water production during the period from receiving the stop water extraction signal to the electric control faucet 8 delaying closing for n seconds, and the water production time (the duration of this round of water extraction) is T 取水 (min) = (L 定量 -L0) / L 净水流量计 .

[0138] The water purification equipment can also implement a fixed-time quantitative water extraction guarantee plan to ensure that water production can be stopped normally when the flow meter fails. Select the flow lower limit Q0 of this water purification equipment to calculate the quantitative water extraction time t 取水 (this round threshold duration) t 取水 (min) = L 定量 / Q0 (L / min), take T 取水 With t 取水 The first one to arrive will decide to stop drawing water.

[0139] In this embodiment, by controlling the water faucet to close after a delay period in the pipeline, the water flow drive device and the water faucet can be controlled to close at staggered times when the water purification equipment is closed, thereby reducing the pressure of water in the water purification pipeline on the water faucet when it is closed, thereby improving the faucet shaking caused by water pressure and improving the reliability of the water purification equipment.

[0140] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
