[0109] Figure 3 is a schematic diagram of an electronic device according to an embodiment of this application. Detailed Implementation
[0110] The present application will be further described in detail below with reference to Figures 1-3.
[0111] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments 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.
[0112] This application provides an intelligent and accurate method for calculating filter lifespan, executed by an electronic device. This electronic device can be a server or a terminal device. The server can be a standalone physical server, a server cluster consisting of multiple physical servers, a distributed device, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, and this application does not impose any limitations on this.
[0113] Referring to Figure 1, the method includes: steps S101, S102, S103, and S104, wherein:
[0114] Step S101: Obtain filtered water quality information and qualified water quality information. If the filtered water quality information and qualified water quality information are inconsistent, determine the lifespan of the first filter element.
[0115] In the application embodiment, the filtered water quality information is the water quality information after it has been filtered by the water purifier, and the qualified water quality information is the water quality information after it has been filtered by the water purifier for the first time.
[0116] Specifically, each water purifier is equipped with a monitoring device at both its inlet and outlet to detect water quality. This device collects water quality information in real time as the purifier operates and transmits this information to the electronic device. Upon receiving the water quality information, the electronic device categorizes and stores it in a database based on the operating time and the inlet / outlet. It then sets the water quality information after the first pass through the purifier as qualified water quality information. Subsequently, the electronic device compares the filtered water quality information with the qualified water quality information. If the filtered water quality information does not match the qualified water quality information, it means that impurities still exist in the water after filtration by the filter cartridge, and the water quality does not meet the standards for use. The electronic device then analyzes and processes the data to determine the lifespan of the corresponding first filter cartridge.
[0117] Step S102: Obtain user usage information and determine the lifespan of the second filter element based on the user usage information.
[0118] In the application embodiment, the user information includes filter cartridge usage time and water flow rate.
[0119] Specifically, each filter cartridge in the water purifier has a monitoring device at its installation location to detect user usage information. After receiving the user usage information transmitted by the monitoring device, the electronic device will store it in the database according to the filter cartridge usage time and water flow rate. Then, the electronic device will calculate the lifespan of the second filter cartridge according to the second filter cartridge lifespan calculation formula transmitted by the staff.
[0120] The lifespan of the second filter element corresponding to the user's usage information is calculated using the following formula: Second filter element lifespan = [100% - (n / N + m / M) / 2] * 100%
[0121] Where n represents the user's filter cartridge usage time, m represents the water flow rate after n days, N represents the total number of days the filter cartridge is used, and M represents the total water flow rate of the filter cartridge after N days.
[0122] Step S103: Determine the lifespan overlap based on the lifespan of the first filter element and the lifespan of the second filter element.
[0123] Specifically, the electronic device plots a curve image of the lifespan of the first filter element in the database with usage time as the x-axis and the lifespan of the first filter element as the y-axis, and sets the plotted image as the first curve image; at the same time, the electronic device plots a curve image of the lifespan of the second filter element in the database with usage time as the x-axis and the lifespan of the second filter element as the y-axis, and sets the plotted image as the second curve image; then the electronic device overlays the first curve image and the second curve image, and uses an image algorithm to determine the degree of overlap of lifespans.
[0124] Step S104: If the lifespan overlap is greater than or equal to the preset overlap, then determine the target filter lifespan.
[0125] Specifically, after determining the lifespan overlap, the electronic device matches the lifespan overlap with the preset overlap. If the lifespan overlap is greater than the preset overlap, it means that the filtered water quality meets the user's needs. If the lifespan overlap is less than the preset overlap, it means that the filtered water quality does not meet the user's needs at all, and the filter cartridge has far exceeded its lifespan. If the lifespan overlap is greater than or equal to the preset overlap, it means that the filtered water quality just meets the user's needs, and the filter cartridge has reached its lifespan. The electronic device then sets the weighted average of the lifespans of the first and second filter cartridges corresponding to the filter cartridge overlap being equal to the preset overlap as the target filter cartridge lifespan.
[0126] This application provides an intelligent and accurate method for calculating filter cartridge lifespan. After acquiring filtered water quality information and qualified water quality information, the filtered water quality information is compared with the qualified water quality information. If the filtered water quality information and qualified water quality information are inconsistent, it indicates that impurities still exist in the water after filtration by the filter cartridge, and the water quality does not meet the usage standard. The lifespan of the first filter cartridge is then determined. Next, user usage information is obtained and analyzed to calculate the corresponding lifespan of the second filter cartridge. After determining the lifespan of the second filter cartridge, the overlap between the lifespan of the first filter cartridge and the lifespan of the second filter cartridge is calculated to determine the lifespan overlap, thus avoiding the limitations and errors that may exist in a single judgment method. Then, the lifespan overlap is matched with a preset overlap. If the lifespan overlap is greater than or equal to the preset overlap, it indicates that the filtered water quality just meets the user's needs, and the filter cartridge has reached its service life, thus determining the target filter cartridge lifespan. This improves the accuracy of filter cartridge lifespan calculation.
[0127] If the filtered water quality information is inconsistent with the qualified water quality information, the lifespan of the first filter element is determined, including: splitting the filtered water quality information into multiple sub-filtered water quality information; determining the factors affecting water quality based on the qualified water quality information; determining the weight information based on the factors affecting water quality; determining the water quality score corresponding to each sub-filtered water quality information based on the weight information; if the water quality score is equal to the preset water quality score, obtaining the filter element usage time; and obtaining the lifespan of the first filter element based on the filter element usage time.
[0128] In this embodiment of the application, the qualified water quality information is the water quality information after the first filtration by the water purifier.
[0129] Specifically, the electronic equipment breaks down the filtered water quality information based on the water quality indicators set by the staff, resulting in multiple sub-filtered water quality information. Among these, the water quality indicators include the content of dissolved solids (TDS), pH value, hardness (measured by the content of substances such as calcium carbonate), microbial content (such as the number of bacteria and viruses), and heavy metal content (such as the content of elements like lead, mercury, and cadmium).
[0130] Furthermore, the electronic device compares qualified water quality information with water quality indicators to identify factors affecting water quality and sets them as influencing factors. Based on water quality assessment knowledge, the electronic device determines the importance of each influencing factor and assigns its corresponding weight information. For example, dissolved solids content has a weight of 0.2, pH has a weight of 0.1, hardness has a weight of 0.15, microbial content has a weight of 0.3, and heavy metal content has a weight of 0.25. The electronic device calculates the water quality score for each sub-filtration water quality information based on the weight information corresponding to each influencing factor. The electronic device then compares the water quality score with a preset water quality score. If the water quality score equals the preset score, it indicates that the water quality does not meet the staff's usage standards. The electronic device then generates a filter cartridge usage time acquisition command and transmits it to the filter cartridge timing device, which then transmits the filter cartridge usage time to the electronic device. Upon receiving the filter cartridge usage time, the electronic device sets the corresponding filter cartridge usage time as the first filter cartridge lifespan.
[0131] Obtain user usage information and determine the lifespan of the second filter element based on this information. This includes: inputting the filter element usage time and water flow rate into the filter element lifespan calculation formula to calculate and determine the lifespan of the second filter element; and determining the filter element calculation formula corresponding to the lifespan of the second filter element, including:
[0132] The lifespan of the second filter element corresponding to the user's usage information is calculated using the following formula: Second filter element lifespan = [100% - (n / N + m / M) / 2] * 100%
[0133] Where n represents the user's filter cartridge usage time, m represents the water flow rate after n days, N represents the total number of days the filter cartridge is used, and M represents the total water flow rate of the filter cartridge after N days.
[0134] In this embodiment of the application, the user information includes filter cartridge usage time and water flow rate.
[0135] Specifically, after receiving user usage information, the electronic device classifies and stores the filter cartridge usage time and water flow rate one-to-one. Then, the electronic device filters the filter cartridge usage time and water flow rate to determine the corresponding filter cartridge usage time n, water flow rate M after n days, total number of days of filter cartridge use N, and total water flow rate M after N days. These values are then substituted into the formula to calculate the corresponding second filter cartridge lifespan.
[0136] After determining the lifespan of the second filter element, the process further includes: if the water quality score is less than the preset water quality score, obtaining filter element replacement information; inputting the filter element replacement information into the standard filter element lifespan calculation formula to calculate and determine the standard filter element lifespan; and determining the standard filter element lifespan calculation formula corresponding to the standard filter element lifespan, including:
[0137] The standard filter life corresponding to the standard filter life is calculated using the following formula: C = 100% - N now / N1 C=100%-M now / M1
[0138] Where, N now Indicates the total number of days of use before replacing the filter element, M now The value indicates the total water flow before the filter cartridge is replaced, and C indicates the standard filter cartridge lifespan.
[0139] In this embodiment, the filter replacement information includes the total number of days of use and the total water flow before the filter replacement.
[0140] Specifically, the electronic device compares the water quality score with the preset water quality score. If the water quality score is lower than the preset water quality score, it indicates that the water quality is poor and cannot meet the needs of the staff. The electronic device then generates a filter replacement information acquisition command and transmits it to the corresponding monitoring device. After receiving the filter replacement information acquisition command, the monitoring device immediately transmits the filter replacement information to the electronic device. After receiving the filter replacement information, the electronic device immediately uses the filter replacement information, including the total number of days of use before filter replacement and the total water flow, into the formula to calculate and determine the standard filter life.
[0141] Determine the lifespan overlap based on the lifespan of the first filter element and the lifespan of the second filter element, including: plotting a first curve image based on the lifespan of the first filter element; plotting a second curve image based on the lifespan of the second filter element; determining the image overlap based on the first curve image and the second curve image; and determining the lifespan overlap based on the image overlap.
[0142] Specifically, the electronic device plots a first curve with the number of days from the start to the end of the filter's use as the x-axis and the lifespan of the first filter element as the y-axis. Assume the lifespan of the first filter element is 150 days. When x = 0, the filter element has just begun use, and the remaining lifespan ratio y = 1, meaning the curve's starting point is (0, 1). As time progresses, when x = 150, the filter element's lifespan is exhausted, and the remaining lifespan ratio y = 0, meaning the endpoint is (150, 0). Simultaneously, the electronic device plots a second curve in the same manner.
[0143] Furthermore, the electronic device plots the first curve image and the second curve image in the same coordinate system, analyzes and processes the images, and determines the image overlap degree corresponding to the first curve image and the second curve image; then the electronic device matches the image overlap degree with the corresponding filter element and sets it as the lifespan overlap degree of the filter element.
[0144] Determining the target filter life includes: determining a first weighted average based on the first filter life; determining a second weighted average based on the second filter life; and calculating the mean of the first weighted average and the second weighted average to determine the target filter life.
[0145] In the embodiments of this application, the lifespan of the first filter element includes multiple components, and the lifespan of the second filter element includes multiple components.
[0146] Specifically, the electronic device uses historical data to determine the relevant factors affecting the lifespan of the first filter element and assigns corresponding weights to these factors. For example, factors affecting filter lifespan may include the operating environment (such as temperature and humidity), the quality of the filtered water (pH, hardness, impurity content, etc.), and usage frequency (duration or number of times the filter is turned on each day). The electronic device then calculates a first weighted average based on the weights assigned to these factors; simultaneously, it calculates a second weighted average using the same method; finally, the electronic device calculates the mean of the first and second weighted averages and sets the resulting average as the target filter lifespan.
[0147] After determining the target filter cartridge lifespan, the following steps are also taken: obtaining the number of days of filter cartridge replacement and the actual water flow rate at each filter cartridge replacement; and then using the number of days of replacement to calculate the total optimized usage time in the formula for calculating the total optimized usage time.

[0149] Calculate the total time for optimization using the following formula: N=[(n1+n2+n3+……+n x ) / x] / (100-C)
[0150] Where, {n1+n2+n3+……+n x} indicates the number of days the filter cartridge is used each time it is replaced, and C indicates the standard filter cartridge lifespan;
[0151] The actual flow rate is substituted into the optimized total flow rate calculation formula to obtain the optimized total flow rate.
[0152] The optimized total flow rate corresponding to the actual flow rate includes:
[0153] Calculate the optimized total flow rate using the following formula: M=[(m1+m2+m3+……+m x ) / x] / (100-C)
[0154] Where, {m1+m2+m3+……+m x} indicates the actual water flow rate each time the filter cartridge is replaced, and C indicates the standard filter cartridge lifespan;
[0155] The optimization plan is determined based on the total usage time and the total water flow rate.
[0156] Specifically, water purifiers are equipped with monitoring devices that record the number of days the filter cartridge is used and the actual water flow rate each time the filter cartridge is replaced. The monitoring devices transmit the number of days the filter cartridge is used and the actual water flow rate each time the filter cartridge is replaced to the electronic device. After receiving the number of days the filter cartridge is used and the actual water flow rate each time the filter cartridge is replaced from the monitoring devices, the electronic device uses the number of days the filter cartridge is used to calculate the total optimized usage time using the formula to obtain the total optimized usage time.
[0157] The total optimized usage time corresponding to the changed usage days includes;
[0158] Calculate the total time for optimization using the following formula: N=[(n1+n2+n3+……+n x ) / x] / (100-C)
[0159] Where, {n1+n2+n3+……+n x} indicates the number of days the filter cartridge is used each time it is replaced, and C indicates the standard filter cartridge lifespan;
[0160] The actual flow rate is substituted into the optimized total flow rate calculation formula to obtain the optimized total flow rate.
[0161] The optimized total flow rate corresponding to the actual flow rate includes:
[0162] Calculate the optimized total flow rate using the following formula: M=[(m1+m2+m3+……+m x ) / x] / (100-C)
[0163] Where, {m1+m2+m3+……+m x} indicates the actual water flow rate each time the filter cartridge is replaced, and C indicates the standard filter cartridge lifespan;
[0164] Furthermore, the electronic device optimizes the calculation formula for calculating the lifespan of the second filter element based on the optimized total usage time and optimized total water flow, and generates a corresponding optimization scheme.
