Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0055] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0056] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0057] First, the terms used in this application will be explained.

[0058] TDS: Total Dissolved Solids, refers to the total amount of soluble inorganic salts in water, including metal ions such as calcium, magnesium, sodium, potassium, iron, and zinc, as well as non-metallic ions such as sulfates, nitrates, and carbonates. TDS values ​​are usually expressed in milligrams per liter (mg / L) or parts per million (ppm).

[0059] Water purification equipment is a device that removes impurities from water through physical, chemical, or biological methods to improve water quality and ensure drinking water safety. It is widely used in homes, commercial establishments, and industrial sectors. Water purification equipment typically includes one or more filtration units, each equipped with a specific type of filter cartridge, such as a pretreatment filter cartridge (to remove large particles), an activated carbon filter cartridge (to adsorb organic matter and residual chlorine), or a reverse osmosis membrane (to remove dissolved salts and microorganisms).

[0060] As a core component of water purification equipment, the performance of filter cartridges gradually declines over time, requiring regular replacement to maintain effective water purification. Currently, most filter cartridge replacement reminders on the market use a simple logic based on fixed times to remind users to replace the filter cartridges.

[0061] However, the method of reminding filter cartridges to be replaced at fixed times has problems such as inaccurate reminders, premature or late replacement of filter cartridges, which affects user experience and water purification quality.

[0062] To address the aforementioned issues, this application provides a method for prompting filter replacement in water purifiers. This method comprehensively considers various factors affecting the lifespan of water purifier filter cartridges, calculating the impact score for each factor. Based on the actual usage of the filter cartridge, different weights are assigned to each factor. By combining these weights, the filter cartridge's condition is comprehensively evaluated to obtain a comprehensive evaluation value. When the comprehensive evaluation value exceeds a threshold, a replacement prompt is sent to the user, ensuring efficient equipment operation and water quality safety. This method, by integrating multiple factors affecting filter cartridges, achieves accurate replacement reminders, avoids untimely replacement, extends the lifespan of the water purifier, guarantees the water purification effect, ensures the quality of drinking water for users, and improves the user experience.

[0063] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0064] Figure 1 A flowchart illustrating the filter replacement reminder method for the water purification equipment provided in this application embodiment. Figure 1 The implementing entity in this embodiment can be, for example, a filter replacement reminder module installed in a water purification device. Figure 1 As shown in this embodiment, the filter replacement reminder method for the water purification equipment includes:

[0065] S101: Obtain multiple filter cartridge indicators for water purification equipment.

[0066] The filter cartridge specifications include at least two of the following: usage time, flow rate data, water quality data, and pressure difference before and after the filter cartridge.

[0067] Understandably, water purification equipment is equipped with various sensors, and different types of sensors can detect real-time data information of different types of filter cartridge indicators. Among them, filter cartridge indicators are used to evaluate the performance and status of the filter cartridges in the water purification equipment, thereby reflecting the real-time status of the filter cartridges in the water purification equipment. This helps users and the filter cartridge replacement reminder module to more accurately understand the working status of the filter cartridges, and thus determine when to issue a replacement reminder to ensure the safety and purity of the water quality.

[0068] In obtaining multiple filter cartridge parameters, the parameters acquired at any given time are set according to the user's needs, including but not limited to: usage time, flow rate data, water quality data, and at least two of the following: pressure difference before and after the filter cartridge. Furthermore, factors such as geographical location, external environment, and user habits can also affect the acquisition of filter cartridge parameters. This application does not impose any special restrictions on the type and number of filter cartridge parameters.

[0069] The main entity executing this step is the filter replacement reminder module installed in the water purification equipment. This module can acquire corresponding data information in real time through various sensors configured in the water purification equipment, thereby obtaining the corresponding filter indicators. If the filter indicators acquired at this time include: usage time, flow rate data, water quality data, and the pressure difference before and after the filter, the usage time and flow rate data can be statistically analyzed using a single time sensor and flow rate sensor, the water quality data is obtained by using multiple water quality detection sensors to obtain the changes in water quality after using the filter, and the pressure difference before and after the filter is calculated by using multiple pressure sensors to detect the pressure at the filter outlet and inlet respectively.

[0070] For example, the water purification equipment is equipped with various sensors including a timer, a flow meter, a TDS sensor, and a pressure sensor. Different types of sensors are used to determine different types of filter cartridge parameters. The timer is used to determine the usage time of the filter cartridge, the flow meter is used to determine the total water volume passing through the filter cartridge, the TDS sensor is used to detect the dissolved concentration in the water in real time, and the pressure sensor is installed at the inlet and outlet of the filter cartridge to monitor the pressure difference before and after the filter cartridge in real time. Through the timer, flow meter, TDS sensor, and pressure sensor, the usage time of the filter cartridge is found to be 3 months, the total water volume passing through the filter cartridge is 5000L, the TDS values ​​at the inlet and outlet of the filter cartridge are 200ppm and 30ppm, respectively, and the pressure difference before and after the filter cartridge is 0.7bar.

[0071] S102: Determine the corresponding index score for each filter element index based on the values ​​of each filter element index.

[0072] S103: Based on the index scores corresponding to each filter element index and the weights corresponding to each filter element index, determine the filter element evaluation value.

[0073] Among them, the index score is used to characterize the degree of influence of filter index on filter life, and the filter evaluation value is used to quantify the current state and performance of the filter.

[0074] Understandably, the score of an indicator reflects the degree to which the corresponding filter element indicator affects the filter element's lifespan. For example, if the water quality before filtration by the current water purifier is very poor, then the corresponding water quality data indicator score will be high, indicating that the current water quality has a significant impact on the filter element's lifespan. The filter element evaluation value is a comprehensive value based on multiple filter element indicators, and the higher the evaluation value, the more severe the performance degradation of the filter element, and the greater the likelihood that it needs to be replaced.

[0075] Furthermore, in filter replacement reminders, weighting is a key factor used to adjust the relative importance of different filter cartridge indicators when calculating the filter cartridge evaluation value. The weighting can be adjusted according to the specific usage environment and equipment requirements, or it can be preset according to different geographical locations. Assigning different weights to different filter cartridge indicators is to more accurately reflect their impact on filter cartridge lifespan, thereby providing more reliable filter cartridge replacement recommendations and ensuring the efficient operation of water purification equipment and the health and safety of users. This application does not impose any special restrictions on the setting of weights for different filter cartridge indicators.

[0076] Based on the specific values ​​of each filter element indicator obtained, the corresponding indicator score for each filter element indicator is determined. Then, combined with the weights corresponding to each filter element indicator, the indicator scores corresponding to each filter element indicator are weighted and calculated, and the resulting weighted value is determined as the filter element evaluation value.

[0077] For example, based on the currently acquired filter cartridge usage time, flow rate data, water quality data, and pressure difference across the filter cartridge, the corresponding index scores for each filter cartridge indicator are determined. The index score for a usage time of 3 months is 60, the index score for a total water volume of 5000L is 50, the index score for a TDS change of 170ppm at the filter cartridge inlet and outlet is 80, and the index score for a pressure difference of 0.7bar across the filter cartridge is 80. Weights are assigned based on the impact of each filter cartridge indicator on the filter cartridge lifespan, with usage time having a weight of 0.2, total water volume having a weight of 0.3, water quality data having a weight of 0.3, and the pressure difference across the filter cartridge having a weight of 0.2. Combining the index scores and weights of each filter cartridge indicator, the filter cartridge evaluation value for the water purification equipment is calculated, and this filter cartridge evaluation value is 67.

[0078] S104: Send a prompt message to the terminal when the filter evaluation value exceeds the preset threshold.

[0079] The preset threshold can be, for example, 80, and the prompt message is used to remind the user to replace the filter cartridge of the water purifier.

[0080] If the filter cartridge evaluation value exceeds the preset threshold, it indicates that the filter cartridge's water purification effect has significantly decreased. At this time, the filter cartridge replacement reminder module sends a replacement reminder to the user to ensure that the user can replace the filter cartridge in a timely manner to maintain the best performance of the equipment and water quality safety. If the filter cartridge evaluation value does not exceed the preset threshold, it indicates that the filter cartridge's performance is still within an acceptable range. At this time, the filter cartridge replacement reminder module continues to monitor the filter cartridge's various indicator data and makes another determination on whether the filter cartridge evaluation value exceeds the preset threshold.

[0081] For example, if the current filter evaluation value is 67, and 67 < 80, it indicates that the current filter evaluation value has not exceeded the preset threshold. In this case, the filter can still guarantee the water purification effect required by the user, and the filter replacement reminder module does not need to send a replacement reminder; it can continue to acquire various filter indicators. If the current filter evaluation value is 85, and 85 > 80, it indicates that the current filter evaluation value has exceeded the preset threshold. In this case, the water purification effect of the filter has significantly decreased and cannot guarantee the water purification effect required by the user. The filter replacement reminder module will then send a reminder message to prompt the user to replace the filter. This reminder message could be: "Dear user, the filter evaluation value of your water purifier has reached 85. We recommend that you replace the filter as soon as possible to ensure water quality safety and the best performance of the equipment."

[0082] The filter replacement reminder method for water purifiers provided in this embodiment acquires multiple filter indicators of the water purifier and determines the corresponding indicator score for each indicator based on its value. Based on the indicator scores and weights of each indicator, a filter evaluation value is determined. When the filter evaluation value exceeds a preset threshold, a reminder message is sent to the terminal. This method, by integrating multiple filter indicators, achieves accurate filter replacement reminders, extends the service life of the water purifier, ensures the water purification effect, and improves the user experience.

[0083] Figure 2 A flowchart illustrating the filter replacement reminder method for the water purification equipment provided in this application embodiment. Figure 2 .like Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, the filter replacement reminder method for water purifiers is described in detail. The filter replacement reminder method for water purifiers shown in this embodiment includes:

[0084] S201: Obtain multiple filter element indicators for water purification equipment.

[0085] Step S201 is similar to step S101 above, and will not be repeated here.

[0086] S202: When the filter element index is the usage time or flow rate data, the filter element usage rate corresponding to the filter element index is determined based on the filter element index and the preset threshold corresponding to the filter element index.

[0087] S203: Based on the filter element usage rate and the preset correspondence between filter element usage rate and indicator score, determine the indicator score corresponding to the filter element indicator.

[0088] Among them, the filter element usage rate is used to indicate the degree or proportion that has been used within the preset service life cycle of the filter element.

[0089] Understandably, when the filter cartridge indicators are usage time or flow rate data, as the usage time or the total amount of water filtered increases, the water purification effect of the filter cartridge will also decrease. In other words, the usage rate will affect the water purification effect of the filter cartridge, thereby affecting the indicator score of the corresponding filter cartridge.

[0090] The filter replacement reminder module has a pre-stored correspondence between preset filter usage rate and indicator score. As the filter usage rate increases, the corresponding indicator score of the filter also decreases. Moreover, the indicator score of different filter indicators corresponds to a unique range of filter usage rate. Therefore, after determining the filter usage rate corresponding to the current filter indicator, the corresponding indicator score can be obtained.

[0091] When the filter element indicator is usage time, the ratio between the currently acquired usage time and the preset threshold corresponding to the usage time is calculated, and the result is determined as the filter element utilization rate corresponding to the usage time. When the filter element indicator is flow rate data, the ratio between the currently acquired flow rate data and the preset threshold corresponding to the flow rate data is calculated, and the result is determined as the filter element utilization rate corresponding to the flow rate data.

[0092] Based on the filter usage rate of the usage duration and flow data obtained in this instance, and combined with the correspondence between filter usage rate and indicator score pre-stored in the filter replacement module, the indicator score corresponding to the usage duration and flow data of each filter indicator is determined.

[0093] For example, the preset usage time threshold is 6 months. If the current usage time is 3 months, the filter cartridge usage rate corresponding to the usage time can be calculated as 50%. Based on the pre-stored correspondence between filter cartridge usage rate and indicator score for usage time, specifically: "If the filter cartridge usage rate is 0-20%, the corresponding indicator score is 20; if the filter cartridge usage rate is 21-40%, the corresponding indicator score is 40; if the filter cartridge usage rate is 41-60%, the corresponding indicator score is 60; if the filter cartridge usage rate is 61-80%, the corresponding indicator score is 80; if the filter cartridge usage rate is 81-100%, the corresponding indicator score is 100," the indicator score corresponding to the usage time filter cartridge indicator can be determined to be 60. If the current water purification system... The total water volume filtered by the filter cartridges is 5000L, and the total water volume that the filter cartridges of this water purifier can filter is 10000L. Therefore, the filter cartridge utilization rate corresponding to the flow rate data can be calculated to be 50%. Based on the pre-stored correspondence between the filter cartridge utilization rate and the index score of the flow rate data, and specifically as follows: if the filter cartridge utilization rate is 0-20%, the corresponding index score is 10; if the filter cartridge utilization rate is 21-40%, the corresponding index score is 30; if the filter cartridge utilization rate is 41-60%, the corresponding index score is 50; if the filter cartridge utilization rate is 61-80%, the corresponding index score is 70; and if the filter cartridge utilization rate is 81-100%, the corresponding index score is 100, the index score corresponding to the filter cartridge indicator of usage time can be determined to be 50.

[0094] S204: Determine the difference in water quality data between raw water and wastewater.

[0095] S205: Determine the index score corresponding to the water quality data based on the raw water quality data and the difference between the raw water quality data and the water quality data.

[0096] Understandably, by comparing the water quality data of the raw water end and the wastewater end, the water purification capacity of the filter element can be evaluated, and the difference in water quality data reflects the purification effect of the filter element during the filtration process. The smaller the difference in water quality data, the better the purification effect of the filter element; conversely, the larger the difference, the worse the purification effect of the filter element.

[0097] Using water quality sensors installed at the raw water end and the wastewater end, water quality data at the raw water end before filtration and water quality data at the wastewater end after filtration are obtained respectively. The difference between the raw water end water quality data and the wastewater end water quality data is calculated. Combined with the raw water end water quality data, the difference in water quality data is analyzed and processed to determine the actual water purification effect of the filter cartridge for that time, thereby determining the index score corresponding to the water quality data.

[0098] Understandably, the filter replacement reminder module pre-stores the correspondence between water quality data differences and indicator scores. As the water quality data difference increases, meaning the filter's water purification effect gradually decreases, the corresponding indicator score gradually increases. Furthermore, since water quality varies in different regions, the correspondence between water quality data differences and indicator scores may need to be adjusted according to the water quality conditions in different regions. In other words, the geographical location of the water purification equipment will also affect the correspondence between water quality data differences and indicator scores. For example, if the water quality in region A is poor and the water quality in region B is good, then the water quality range corresponding to different indicator scores in region A will be higher than the water quality range corresponding to the corresponding indicator scores in region B.

[0099] For example, the specific correspondence between the water quality data difference and the indicator score in the area where the water purification equipment is located is as follows: "A water quality data difference of 180 ppm or above corresponds to an indicator score of 100; a water quality data difference of 150-179 ppm corresponds to an indicator score of 80; a water quality data difference of 120-149 ppm corresponds to an indicator score of 60; a water quality data difference of 90-119 ppm corresponds to an indicator score of 40; a water quality data difference of 60-89 ppm corresponds to an indicator score of 20; and a water quality data difference below 60 ppm corresponds to an indicator score of 20." If the currently detected raw water TDS value is 200 ppm and the wastewater TDS value is 30 ppm, it indicates that the current filter cartridge has a poor filtration effect. The corresponding water quality data difference is 170 ppm. Combining the correspondence between the water quality data difference and the indicator score determined by the raw water quality, it can be determined that the indicator score corresponding to this water quality data difference of 170 ppm is 80.

[0100] S206: Based on the pressure difference across the filter element and the pre-set correspondence between the pressure difference and the index score, determine the index score corresponding to the pressure difference across the filter element.

[0101] Understandably, pressure sensors installed at the filter cartridge inlet and outlet monitor the pressure difference across the filter cartridge in real time. This pressure difference reflects the degree of filter cartridge blockage; specifically, as the blockage increases, the resistance to water flow increases, leading to increased inlet pressure and decreased outlet pressure, thus increasing the pressure difference. Furthermore, the filter cartridge replacement reminder module pre-stores the correspondence between the pressure difference and indicator scores. As the pressure difference increases, the blockage level of the filter cartridge increases, and the corresponding indicator score gradually increases.

[0102] For example, the preset correspondence between pressure difference and index score is as follows: "When the pressure difference across the filter element is in the range of 0-0.2 bar, the index score is 20; when the pressure difference across the filter element is in the range of 0.2-0.4 bar, the index score is 40; when the pressure difference across the filter element is in the range of 0.4-0.6 bar, the index score is 60; when the pressure difference across the filter element is in the range of 0.6-0.8 bar, the index score is 80; when the pressure difference across the filter element is in the range of 0.8 bar or above, the index score is 100." The pressure difference across the filter element is monitored in real time by pressure sensors installed at the inlet and outlet. If the inlet pressure is 2.3 bar and the outlet pressure is 1.5 bar, the pressure difference across the filter element is 0.7 bar, and the corresponding index score is 80.

[0103] S207: Determine the filter element evaluation value based on the index scores corresponding to each filter element index and the weights corresponding to each filter element index.

[0104] Based on the scores of the various filter element indicators obtained so far, and combined with the weights corresponding to each filter element indicator, the scores of each filter element indicator are weighted and calculated, and the resulting weighted value is determined as the filter element evaluation value.

[0105] Understandably, the weights of different filter cartridge indicators can be adjusted based on the actual usage of the filter cartridge. For example, in areas with poor water quality, the weight of water quality data may be increased to reflect its greater impact on the filter cartridge; in environments with high usage frequency, the weights of usage time and flow rate data may be increased.

[0106] Optionally, the usage duration is the duration of the water usage period; before determining the filter element evaluation value based on the index scores corresponding to each filter element index and the weights corresponding to each filter element index, the filter element replacement reminder method of the water purification equipment further includes:

[0107] If the usage time in the second time period exceeds the duration threshold, the weight corresponding to the usage time will be increased.

[0108] The second time period can be, for example, 15 days, and the duration threshold can be, for example, 90 hours.

[0109] For example, if the weight of the filter cartridge indicator "current usage time" is 0.2, and based on the cumulative usage time of the filter cartridge obtained within 15 days, if the cumulative usage time within 15 days is 95 hours (95 hours > 90 hours), it indicates that the user is in a high-frequency water usage environment within 15 days. In this case, the weight of the filter cartridge indicator "usage time" is adjusted to 0.4, and the weights of other filter cartridge indicators are adjusted adaptively. Specifically, the weight of total water volume is adjusted to 0.2, the weight of water quality data is adjusted to 0.2, and the weight of the pressure difference before and after the filter cartridge is adjusted to 0.2.

[0110] Optionally, before determining the filter cartridge evaluation value based on the index scores and weights corresponding to each filter cartridge index, the filter cartridge replacement reminder method for the water purification equipment further includes:

[0111] If the traffic data exceeds the traffic threshold in the third time period, the weight of the traffic data will be increased.

[0112] The third time period can be, for example, 15 days, and the flow threshold can be, for example, 11 tons.

[0113] For example, if the weight of the filter element indicator flow rate is 0.3, the total water volume filtered by the filter element within that time period is determined based on the cumulative total water volume filtered by the filter element over 15 days. If the total water volume filtered by the filter element over 15 days is 12 tons, and 12 tons > 11 tons, it indicates that the user is in a high-frequency water usage environment within 15 days. In this case, the weight of the filter element indicator flow rate is adjusted to 0.4, and the weights of other filter element indicators are adjusted accordingly. Specifically, the weight of usage time is adjusted to 0.2, the weight of water quality data is adjusted to 0.2, and the weight of the pressure difference before and after the filter element is adjusted to 0.2.

[0114] Optionally, before determining the filter cartridge evaluation value based on the index scores and weights corresponding to each filter cartridge index, the filter cartridge replacement reminder method for the water purification equipment further includes:

[0115] If the average value of the raw water quality data in the fourth time period is lower than the water quality threshold, then the weight of the water quality data will be reduced.

[0116] The fourth time period can be, for example, 30 days, and the water quality threshold can be, for example, 60 ppm.

[0117] For example, if the weight of the filter element indicator "water quality data" is 0.3, the raw water quality received by the filter element within 30 days is obtained according to a preset time period, and the average value of the raw water quality data for that time period is calculated. If the average value of the 30-day water quality data corresponding to the filter element is 52 ppm, and 52 ppm < 60 ppm, it indicates that the water quality data before filtration by the filter element is stable and the water quality is excellent. At this time, the weight of the filter element indicator "numerical data" is adjusted to 0.2, and the weights of other filter element indicators are adjusted accordingly. Specifically, the weight of usage time is adjusted to 0.3, the weight of total water volume is adjusted to 0.2, and the weight of the pressure difference before and after the filter element is adjusted to 0.3.

[0118] Understandably, the second, third, and fourth time periods are time cycles distinct from different filter element indicators, and each time period represents the time cycle for obtaining data corresponding to different filter element indicators; the second, third, and fourth time periods may be the same or different. This application does not impose any special restrictions on the specific length of the second, third, and fourth time periods.

[0119] S208: If, within the first time period, the cumulative number of times the filter element evaluation value exceeds the preset threshold exceeds the preset number, a prompt message is sent to the terminal.

[0120] The cumulative number of times is used to indicate the total number of times the filter element evaluation value exceeds a preset threshold within a fixed time period. The first time period can be, for example, 10 minutes, and the preset number of times can be, for example, 50 times.

[0121] If the filter cartridge evaluation value exceeds the preset threshold, it indicates that the filter cartridge's water purification effect has significantly decreased. At this time, the time point when the current filter cartridge evaluation value exceeds the preset threshold is determined, and this time point is used as the starting time point to determine the cumulative number of times the filter cartridge evaluation value exceeds the preset threshold within the first time period.

[0122] If the cumulative number of times the filter cartridge evaluation value exceeds the preset threshold within the first time period exceeds the preset number, it indicates that the current decline in the filter cartridge's water purification effect is caused by a decrease in the filter cartridge's filtration effect. At this time, the filter cartridge replacement reminder module sends a replacement reminder to the user to ensure that the user can replace the filter cartridge in a timely manner to maintain the best performance of the equipment and water quality safety. If the cumulative number of times the filter cartridge evaluation value exceeds the preset threshold within the first time period does not exceed the preset number, it indicates that the current decline in the filter cartridge's water purification effect is caused by external environmental factors, and the filter cartridge's filtration effect has not decreased significantly. At this time, multiple filter cartridge indicators of the water purification equipment continue to be acquired to further determine the filter cartridge evaluation value.

[0123] For example, during the first time period of 10 minutes, the filter cartridge evaluation value is calculated at a fixed frequency of 1 second for 10 consecutive minutes. After each filter cartridge evaluation value is calculated, the filter cartridge evaluation value is compared with a preset threshold. If the filter cartridge evaluation value exceeds the preset threshold, it is counted once, and the cumulative number of times the filter cartridge evaluation value exceeds the preset threshold within 10 minutes is determined. If the cumulative number is 55 times, and 55 times > 50 times, it indicates that the current filter cartridge's water purification effect has decreased due to the filter cartridge's own filtration effect. At this time, the reminder mechanism in the filter cartridge replacement reminder module is triggered, and the user can be notified to replace the filter cartridge through reminder devices such as LED lights, displays, or buzzers.

[0124] Optionally, before sending a notification message to the terminal, the filter replacement notification method for the water purification device further includes:

[0125] Based on one or more of the filter cartridge indicators, the maximum usable time of the filter cartridge is predicted, and the maximum usable time is added to the prompt message.

[0126] Understandably, predicting the maximum usable lifespan of a filter element can help users better plan maintenance and filter replacement times to ensure the continuous and efficient operation of the system. This prediction can be based on a simple usage time indicator or a combination of other filter element indicators. This application does not impose any special restrictions on the method used to predict the maximum usable lifespan of a filter element.

[0127] For example, if the current filter cartridge of the water purifier has a service life of 12 months or 2000 liters of water, and the current usage is as follows: "Used for 6 months, processed flow rate of 1200 liters, current pressure difference across the filter cartridge is 0.7 bar (the critical value for the pressure difference across the filter cartridge is 1.0 bar)"; based on the usage time, the remaining life of the filter cartridge is 6 months; based on the filtered water flow rate, the used ratio is 60%, and the remaining flow rate ratio is 40%, corresponding to approximately 4.8 months; considering that the pressure difference is close to the critical value, it is recommended to shorten the predicted life, and the final predicted maximum usable life can be 4 months; at this time, the filter cartridge replacement reminder module generates the following prompt message: "Dear user, based on your usage habits, it is recommended to replace the filter cartridge within 4 months to ensure the best performance of the water purifier."

[0128] Optionally, depending on the type of terminal the user receives the prompt message from, the prompt message generated by the filter replacement prompt module will also be different, and the generation of prompt message is adapted to different types of terminals, so as to provide users with a suitable prompt experience.

[0129] For example, if a user receives a notification message using a water purifier, the message can be broadcast using the voice broadcast module within the purifier to remind the user to replace the filter cartridge; alternatively, an indicator light on the purifier can flash at different frequencies and colors. There are no specific restrictions on how the notification message is displayed.

[0130] The filter replacement reminder method for water purification equipment provided in this embodiment obtains multiple filter indicators of the water purification equipment. When the filter indicator is usage time or flow rate data, it determines the filter usage rate corresponding to the filter indicator based on the filter indicator and the preset threshold corresponding to the filter indicator. Based on the filter usage rate and the preset correspondence between filter usage rate and indicator score, it determines the indicator score corresponding to the filter indicator. It determines the water quality data difference between the raw water end water quality data and the wastewater end water quality data, and determines the indicator score corresponding to the water quality data based on the raw water end water quality data and the water quality data difference. Based on the pressure difference before and after the filter, and the preset correspondence between pressure difference and indicator score, it determines the indicator score corresponding to the pressure difference before and after the filter. Based on the indicator scores corresponding to each filter indicator and the weight corresponding to each filter indicator, it determines the filter evaluation value of the filter, and sends a reminder message to the terminal when the filter evaluation value exceeds the preset threshold. This method integrates multiple filter cartridge indicators to provide precise reminders for filter cartridge replacement, avoiding the problem of untimely filter cartridge replacement, extending the service life of water purification equipment, ensuring the purification effect of water purification equipment, ensuring the quality of drinking water for users, and improving the user experience.
