Description

Technical Field

[0001] The present application relates to the technical field of water purifiers, and in particular to a method for monitoring and processing a water purifier and an externally connected monitoring device. Background Art

[0002] With the development of the economy and the gradual improvement of people's living quality, people are paying more and more attention to the quality of household water. Therefore, some families choose to install a water purifier at the faucet so that the tap water can reach the standard for direct drinking. Most current water purifier products use the method of PP filter element + activated carbon + RO membrane to filter tap water. Among them, the RO membrane, as the core part of the water purifier, uses reverse osmosis technology to filter out calcium, magnesium, bacteria, organic matter, inorganic matter, metal ions and radioactive substances in the tap water. However, in areas with poor water quality, the service life of the RO membrane is relatively short, so it needs to be replaced frequently. Since the RO membrane of brand water purifiers uses the exclusive interface of that brand, the RO membrane cannot be universal and the replacement price is expensive. Therefore, more and more people choose to DIY water purifiers to improve the cost performance.

[0003] The water purifier filter element of the DIY water purifier also consists of a PP filter element + activated carbon + RO membrane. The prices and water purification effects of different types of PP filter elements, activated carbon and RO membranes are also different, and the difference is particularly obvious in the selection of RO membranes. As two important parameters of the RO membrane, the salt rejection rate and the flow rate, the prices of RO membranes with different parameters vary greatly. Nowadays, there are a wide variety of water purifier filter elements on the market, and users of DIY water purifiers often don't know which type of water purifier filter element is suitable for their own use.

[0004] In view of the above related technologies, the inventor believes that there is an urgent need for a method for monitoring and processing a water purifier and an externally connected monitoring device to help users select suitable water purifier filter elements by monitoring the daily use of DIY water purifiers. Summary of the Invention

[0005] In order to help users select suitable water purifier filter elements by monitoring the daily use of DIY water purifiers, the present application provides a method for monitoring and processing a water purifier and an externally connected monitoring device.

[0006] In the first aspect of the present application, a water purifier monitoring and processing statistics method is provided, which is applied to a server. The method includes: obtaining water purifier monitoring information; the water purifier monitoring information includes: the TDS value of tap water, filter element parameter information, and filter element usage information; based on the water purifier monitoring information, determining the current working state of the water purifier; the current working state includes: a normal working state and an abnormal working state; when the water purifier is in the normal working state, obtaining the total daily water consumption and the daily water purifier usage times; based on the total daily water consumption and the daily water purifier usage times, calculating the average daily water consumption and the average daily water purifier usage times within a preset time period; based on the average daily water consumption and the average daily water purifier usage times, determining the water usage state; based on preset filter element selection condition information, determining multiple alternative solutions; when the water purifier is in the abnormal working state, based on the water usage state and the multiple alternative solutions, recommending filter element models to the user.

[0007] By adopting the above technical solution, the server determines whether the current working state of the water purifier is normal by obtaining the water purifier monitoring information. When the water purifier is in a normal working state, the server obtains the user's water usage situation by monitoring the total daily water consumption and the daily water purifier usage times. The server obtains the user's demand for selecting a filter element through the preset filter element selection condition information. When the filter element of the current water purifier needs to be replaced, the server recommends the most suitable filter element to the user based on the user's water usage situation and the demand for selecting a filter element.

[0008] Optionally, the filter element parameter information includes: a first desalination rate and a first flow rate value; the filter element usage information includes: a current TDS value and a current flow rate value; the determining the current working state of the water purifier based on the water purifier monitoring information specifically includes: calculating a first TDS value based on the TDS value of tap water and the first desalination rate; calculating a first difference and a first ratio, the first difference being the result value of subtracting the first TDS value from the current TDS value, and the first ratio being the ratio of the current flow rate value to the first flow rate value; when the first difference is within a preset first range and the first ratio is within a preset second range, determining the current working state of the water purifier to be the normal working state.

[0009] By adopting the above technical solution, the server determines the working condition of the water purifier by calculating the difference between the current TDS value and the first TDS value, and the ratio of the current flow rate value to the first flow rate value, and determines the current working state of the water purifier to be the normal working state when the first difference is within the preset first range and the first ratio is within the preset second range by real-time monitoring of the water purifier filter element situation.

[0010] Optionally, after calculating the first difference and the first ratio, the method further includes: when the first difference is outside the preset first range and / or the first ratio is outside the preset second range, determining the current working state of the water purifier as the abnormal working state.

[0011] By adopting the above technical solution, when the first difference is within the preset first range and / or the first ratio is within the preset second range, determining the current working state of the water purifier as the abnormal working state can promptly discover that the filter element of the water purifier cannot be used continuously and needs to be replaced in time.

[0012] Optionally, the water usage state includes: a first water usage state and a second water usage state; determining the water usage state based on the daily average water consumption and the daily average number of times the water purifier is used specifically includes: when the daily average water consumption within the preset time period is greater than or equal to a preset first threshold and / or when the daily average number of times the water purifier is used within the preset time period is greater than or equal to a preset second threshold, determining it as the first water usage state; when the daily average water consumption within the preset time period is less than the preset first threshold and when the daily average number of times the water purifier is used within the preset time period is less than the preset second threshold, determining it as the second water usage state.

[0013] By adopting the above technical solution, the server determines the user's water usage characteristics based on the user's daily average water consumption and the daily average number of times the water purifier is used within the preset time period, so as to subsequently recommend filter elements according to the user's water usage characteristics.

[0014] Optionally, the preset filter element selection condition information includes: pressure bucket selection information and price range selection information; determining multiple alternative solutions based on the preset filter element selection condition information specifically includes: obtaining multiple alternative solutions based on the pressure bucket selection information and the price range selection information.

[0015] By adopting the above technical solution, the server determines multiple alternative solutions based on the preset filter element selection condition information, so as to subsequently recommend filter elements according to the multiple alternative solutions.

[0016] Optionally, after determining multiple options to be selected, the method further includes: obtaining the second desalination rate and the second flow rate value of each option to be selected according to the multiple options to be selected; calculating the second TDS value based on the TDS value of the tap water and the second desalination rate; calculating the estimated usage duration of each option to be selected under the TDS value of the tap water and the water usage state according to the second TDS value and the second flow rate value of each option to be selected; sorting the estimated usage durations in descending order; the recommending the filter element model to the user includes: recommending the options to be selected with the estimated usage duration before the preset ranking according to the result of the descending order sorting.

[0017] By adopting the above technical solution, the estimated service life of each option to be selected is calculated through the second TDS value and the second flow rate value of each option to be selected, and the estimated service lives are sorted to obtain the filter element selection option with a longer service life under the current user's water usage state, and it is recommended to the user.

[0018] Optionally, the recommending the options to be selected with the estimated usage duration before the preset ranking according to the result of the descending order sorting specifically includes: when the user is in the first water usage state, recommending the options to be selected with the second flow rate value greater than or equal to the first flow rate value and the estimated usage duration before the preset ranking; when the user is in the second water usage state, recommending the options to be selected with the estimated usage duration before the preset ranking.

[0019] By adopting the above technical solution, when in the first water usage state, the server recommends the options to be selected with the second flow rate value greater than or equal to the first flow rate value and the estimated usage duration before the preset ranking, and when the user is in the second water usage state, recommends the options to be selected with the estimated usage duration before the preset ranking. It is possible to recommend a filter element more suitable for the user's current water usage state within the user's selection target range, improving the user's subsequent water usage experience.

[0020] In the second aspect of the present application, a water purifier external monitoring device is provided. The device includes an acquisition module, a processing module, and a recommendation module. The acquisition module is used to acquire the TDS value of tap water, water purifier monitoring information, and filter element selection condition information. The processing module is used to determine the current working state of the water purifier based on the water purifier monitoring information. The acquisition module is further used to acquire the total daily water consumption and the daily water purifier usage times. The processing module is further used to calculate the average daily water consumption and the average daily water purifier usage times within a preset time period based on the total daily water consumption and the daily water purifier usage times, determine the water usage state based on the average daily water consumption and the average daily water purifier usage times, determine multiple alternative solutions based on the filter element selection condition information, generate a suitable recommendation solution based on the water usage state and the multiple alternative solutions, and the recommendation module is used to recommend to the user based on the suitable recommendation solution generated by the processing module.

[0021] In the third aspect of the present application, an electronic device is provided, which includes a processor, a memory, a user interface, and a network interface. The memory is used to store instructions, the user interface and the network interface are used to communicate with other devices, and the processor is used to execute the instructions stored in the memory so that the electronic device executes the method described in any one of the first aspects of the present application.

[0022] In the fourth aspect of the present application, a computer-readable storage medium is provided.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The server determines whether the current working state of the water purifier is normal by acquiring the water purifier monitoring information.

[0038] To help users select suitable water purifier filters by monitoring the daily usage of DIY water purifiers, this application provides a water purifier monitoring and processing method, which is applied to a server. Referring to Figure 1 and Figure 2 , which show a schematic flow diagram of a water purifier monitoring and processing method provided by an embodiment of this application and a schematic diagram of a DIY water purifier provided by an embodiment of this application, including the following steps S101-S107:

[0039] Step S101: Obtain water purifier monitoring information; the water purifier monitoring information includes: the TDS value of tap water, filter element parameter information, and filter element usage information.

[0040] In the above step, the server obtains the water purifier monitoring information.

[0041] Specifically, in this technical solution, as Figure 2As shown in the figure, the filter element of the water purifier includes a PP filter element, activated carbon, and a RO membrane. The PP filter element and the activated carbon are both installed in corresponding filter bottles, and the RO membrane is installed in the RO membrane housing. The water outlet of the filter bottle of the PP filter element is connected to the water inlet of the filter bottle of the activated carbon through a water conduit, and the water outlet of the filter bottle of the activated carbon is connected to the water inlet of the RO membrane housing where the RO membrane is installed through a water conduit. Tap water first enters from the water inlet of the filter bottle of the PP filter element, and the sediment in the tap water is filtered out by the PP filter element. Then it flows into the water inlet of the filter bottle of the activated carbon from the water outlet of the filter bottle of the PP filter element. After the large-diameter pollutants and residual chlorine are filtered out by the activated carbon, it then flows into the water inlet of the RO membrane housing of the RO membrane from the water outlet of the filter bottle of the activated carbon. Then, the calcium, magnesium, bacteria, organic matter, inorganic matter, metal ions, and radioactive substances are filtered out by the RO membrane, so as to achieve the effect of reducing the TDS value of tap water. Among them, the TDS value is the value of the total dissolved solids in water. When the TDS value is 0-9, it is pure water; when the TDS value is 10-60, it is mountain spring water or mineralized water; when the TDS value is 60-100, it is purified water; when the TDS value is 100-300, it is tap water. If the TDS value is above 300, it is polluted water. This application monitors the daily use of the DIY water purifier by users. When the core filter element RO membrane inside the current DIY water purifier needs to be replaced, combined with the specific water usage situation of the user and the filter element selection conditions, it recommends a suitable RO membrane for the user. Therefore, the water purifier monitoring information is the TDS value of tap water, the filter element parameter information, and the filter element usage information obtained by the server through the monitoring device.

[0042] Step S102: Based on the water purifier monitoring information, determine the current working state of the water purifier; the current working state includes a normal working state and an abnormal working state.

[0043] In the above steps, the server determines the current working state of the water purifier according to the obtained filter element parameter information and filter element usage information.

[0044] Specifically, in this technical solution, the filter element parameter information includes the first desalination rate and the first flow rate value, that is, the desalination rate of the RO membrane produced by the manufacturer and the flow rate value per second calculated according to the theoretical flux of the RO membrane. The desalination rate of the RO membrane and the theoretical flux of the RO membrane are provided by the manufacturer. The desalination rate of the RO membrane on the market is 95%-98%, and the theoretical fluxes are 50G, 75G, 100G, 200G, 400G, 600G, 800G, 1000G. The greater the flux, the higher the water outlet efficiency of the RO membrane; taking 200G as an example, it represents that the daily water filtration volume of the RO membrane is 200 gallons. The filter element usage information includes the current TDS value and the current flow rate value, that is, the TDS value detected after being filtered by the filter element and the current flow rate value per second of the water purifier. The server will determine whether the water purifier is currently in a normal working state or an abnormal working state according to the obtained filter element parameter information and filter element usage information.

[0045] In a possible implementation, referring to Figure 3 , which shows the flowchart of a water purifier monitoring and processing method provided by an embodiment of the present application Figure 1 , step S102 specifically includes the following steps S201 - S203:

[0046] Step S201: Calculate the first TDS value based on the TDS value of tap water and the first desalination rate.

[0047] In the above step, the server will calculate the first TDS value according to the TDS value of tap water and the first desalination rate.

[0048] Specifically, in this technical solution, the first TDS value is the theoretical TDS value of tap water after passing through the RO membrane. Its calculation formula is: theoretical TDS value = tap water TDS value * (1 - RO membrane desalination rate). For example, if the TDS value of the tap water currently used by the user is 100 and the RO membrane desalination rate is 98%, then the theoretical TDS value is 2.

[0049] Step S202: Calculate the first difference and the first ratio. The first difference is the result value of subtracting the first TDS value from the current TDS value, and the first ratio is the ratio of the current flow value to the first flow value.

[0050] In the above step, the server uses the current TDS value minus the first TDS value to obtain the first difference; calculates the ratio of the current flow value to the first flow value to obtain the first ratio.

[0051] For example, the current TDS value detected by the monitoring device is 5, and the first TDS value is 2, then the first difference is 3; the flux of the RO membrane obtained by the monitoring device is 200G, 1G = 3.785L, then by converting 200G into ml and dividing by the number of seconds in 24 hours, that is, 200 * 3.785 * 1000 / 86400, the first flow value can be obtained as 8.76ml / s; the current flow value obtained by the monitoring device is 8ml / s, then the first ratio is 0.91.

[0052] Step S203: When the first difference is within a preset first range and the first ratio is within a preset second range, determine that the current working state of the water purifier is the normal working state.

[0053] In the above step, when the server calculates that the first difference is within a preset first range and the first ratio is within a preset second range, it determines that the current working state of the water purifier is the normal working state.

[0054] Specifically, in this technical solution, the preset first range is 0 - 30, and the preset second range is 0.8 - 1. In the above example, the first difference is 3 and the first ratio is 0.91, both of which are within the preset ranges, so it can be determined that the current working state of the water purifier is the normal working state.

[0055] In a possible implementation manner, referring to Figure 4 which shows the flowchart of a water purifier monitoring and processing method provided by an embodiment of the present application Figure 2 after step S202, the following step S301 is further included:

[0056] Step S301: When the first difference is outside the preset first range and / or the first ratio is outside the preset second range, determine that the current working state of the water purifier is the abnormal working state.

[0057] In the above step, when the server calculates that the first difference is outside the preset first range and / or the first ratio is outside the preset second range, it determines that the current working state of the water purifier is the abnormal working state.

[0058] Step S103: When the water purifier is in the normal working state, obtain the total daily water consumption and the daily water purifier usage times.

[0059] In the above step, when the server determines that the water purifier is in the normal working state, it obtains the total daily water consumption and the daily water purifier usage times.

[0060] Specifically, in this technical solution, due to the working characteristics of the RO membrane, an RO booster pump must be used to filter water, and when the RO membrane filters water, a certain proportion of wastewater will be generated, and the ratio of its water output to the wastewater is 1:n. Therefore, the server will monitor the water output after the RO membrane filters water every day, and calculate the total daily water consumption as the water output * (1 + n). The server will monitor the number of times the booster pump is switched on and off to obtain the daily water purifier usage times.

[0061] Step S104: Based on the total daily water consumption and the daily water purifier usage times, calculate the average daily water consumption and the average daily water purifier usage times within a preset time period.

[0062] In the above step, the server will calculate the average daily water consumption and the average daily water purifier usage times within the preset time period after the preset time period according to the total daily water consumption and the daily water purifier usage times.

[0063] Specifically, in this technical solution, the preset time period is 30 days. When using the monitoring device externally connected to the water purifier of this application, the externally connected monitoring device of the water purifier will monitor the total daily water consumption and the daily water purifier usage times of the user within every 30 days. Then, add up all the total daily water consumptions within these 30 days and divide by 30 to obtain the average daily water consumption; add up the daily water purifier usage times within these 30 days and divide by 30 to obtain the average daily water purifier usage times.

[0064] Step S105: Determine the water usage status based on the average daily water consumption and the average daily water purifier usage times.

[0065] In the above step, the server determines the user's water usage status according to the average daily water consumption and the average daily water purifier usage times.

[0066] Specifically, in this technical solution, the water usage status includes a first water usage status and a second water usage status. Among them, the first water usage status is a status of relatively high water consumption, and the second water usage status is a status of relatively low water consumption.

[0067] In a possible implementation manner, referring to Figure 5 , which shows the flow schematic diagram of a water purifier monitoring and processing method provided by an embodiment of this application Figure 3 , step S105 specifically includes the following steps S401 - S402:

[0068] Step S401: When the average daily water consumption within the preset time period is greater than or equal to the preset first threshold and / or when the average daily water purifier usage times within the preset time period is greater than or equal to the preset second threshold, determine it as the first water usage status.

[0069] In the above step, when the average daily water consumption within the preset time period is greater than or equal to the preset first threshold and / or when the average daily water purifier usage times within the preset time period is greater than or equal to the preset second threshold, the server determines the user's water usage status as the first water usage status.

[0070] Specifically, in this technical solution, the preset first threshold is 10L, and the preset second threshold is 20 times. For example, if the average daily water consumption of user A within every 30 days is 12L and the average daily water purifier usage times within every 30 days is 20 times, then it can be determined that the water usage status of user A is a status of relatively high water consumption; if the average daily water consumption of user B within every 30 days is 9L and the average daily water purifier usage times within every 30 days is 23 times, then it can be determined that the water usage status of user B is a status of relatively high water consumption; if the average daily water consumption of user C within every 30 days is 15L and the average daily water purifier usage times within every 30 days is 15 times, then it can be determined that the water usage status of user C is a status of relatively high water consumption.

[0071] Step S402: When the average daily water consumption within a preset time period is less than a preset first threshold and when the average daily water purifier usage times within the preset time period is less than a preset second threshold, it is determined as the second water usage state.

[0072] In the above step, when the average daily water consumption within a preset time period is less than a preset first threshold and when the average daily water purifier usage times within the preset time period is less than a preset second threshold, the server determines that the user's water usage state is the second water usage state.

[0073] For example, if the average daily water consumption of user D within every 30 days is 5L and the average daily water purifier usage times within every 30 days is 10 times, it can be determined that the water usage state of user D is a state of less water consumption.

[0074] Step S106: Based on the preset filter selection condition information, determine multiple alternative solutions.

[0075] In the above step, the server determines multiple alternative solutions according to the filter selection condition information selected by the user.

[0076] Specifically, in this technical solution, the preset filter selection condition information is the filter selection condition information selected when the user uses the monitoring device externally connected to the water purifier. The filter selection condition information includes: pressure bucket selection information and price range selection information.

[0077] In a possible implementation manner, referring to Figure 6 , which shows the process schematic of a water purifier monitoring and processing method provided by an embodiment of the present application Figure 4 , step S106 specifically includes the following step S501:

[0078] Step S501: Based on the pressure bucket selection information and the price range selection information, obtain multiple alternative solutions.

[0079] In the above step, the server obtains multiple alternative solutions according to the pressure bucket selection information and the price range selection information selected by the user.

[0080] Specifically, in this technical solution, the pressure barrel selection information includes whether to install a pressure barrel, and the price range selection information includes multiple price ranges. Since the pressure barrel is connected to the water outlet of the RO membrane, it can store a large amount of filtered tap water at one time and flow out together with the water filtered in real time during use, thus accelerating the water outlet speed. Therefore, matching a pressure barrel with a small-flux RO membrane can effectively solve the problem of slow water outlet of the small-flux RO membrane. However, since some DIY water purifier users believe that storing water through a pressure barrel will affect the quality of the filtered water, whether to install a pressure barrel is one of the options for the filter selection condition information. For example, the price range can be divided into three ranges: below 200 yuan, 200 yuan to 500 yuan, and above 500 yuan. If the filter selection condition information selected by user A is: not installing a pressure barrel, and the price range is above 500 yuan, the server will determine m alternative solutions according to user A's selection.

[0081] In a possible implementation manner, referring to Figure 7 which shows the flowchart of a water purifier monitoring and processing method provided by an embodiment of the present application Figure 5 after step S106, the following steps S601 - S605 are further included:

[0082] Step S601: Obtain the second desalination rate and the second flow rate value of each alternative solution according to multiple alternative solutions.

[0083] In the above step, the server will obtain the second desalination rate and the second flow rate value of each alternative solution.

[0084] Specifically, in this technical solution, the second desalination rate is the desalination rate of the RO membrane in each alternative solution; the second flow rate value is the sum of the flow rate value of the pressure barrel and the flow rate value of the RO membrane. The commonly used pressure barrel on the market is a 3G capacity pressure barrel, and the flow rate value of this pressure barrel is 2L / min, that is, 33.33ml / s; in the above example, the flow rate value calculated by the 200G RO membrane is 8.76ml / s, then the second flow rate value of the 200G RO membrane plus the pressure barrel at this time is 42.09ml / s.

[0085] Step S602: Calculate the second TDS value based on the TDS value of tap water and the second desalination rate.

[0086] In the above step, the server will calculate the second TDS value according to the TDS value of tap water and the second desalination rate.

[0087] Specifically, in this technical solution, the method for calculating the second TDS value is the same as the method for calculating the first TDS value, so it will not be elaborated here.

[0088] Step S603: Calculate the estimated usage duration of each alternative solution under the TDS value and water usage status of tap water based on the second TDS value and the second flow rate value of each alternative solution.

[0089] In the above step, the server calculates the estimated lifespan of the RO membrane of each alternative solution under the TDS value and water usage status of tap water based on the second TDS value and the second flow rate value of each alternative solution.

[0090] Specifically, in this technical solution, since the estimated service life of each RO membrane is related to the manufacturing process, the quality of tap water, and the water consumption of users. Therefore, the estimated service life T = Z 1 / Z 2 , where Z 1 = k*(30 / μ + 0.2X / λ). Where Z 1 is the estimated total water consumption value, Z 2 is the average daily water consumption value of the user, X is the flow rate value after converting the second flow rate value from ml / s to L / h, μ is the increase value of the TDS value of this type of RO membrane per 1000L of water filtered measured by the experimenter according to the TDS value of different tap waters, λ is the attenuation value of the flow rate value of this type of RO membrane per 1000L of water filtered measured by the experimenter according to the TDS value of different tap waters, and k is the coefficient value of the curve obtained by fitting the actual service life of the RO membrane with the total water consumption through matlab software.

[0091] Step S604: Sort the estimated usage durations in descending order.

[0092] In the above step, the server sorts the estimated usage durations from high to low according to the estimated usage duration of each alternative solution.

[0093] Step S605: Recommend the alternative solutions whose estimated usage durations are before the preset ranking according to the result of the descending order sorting.

[0094] In the above step, the server recommends the alternative solutions whose estimated usage durations are before the preset ranking according to the result of the descending order sorting.

[0095] In a possible implementation manner, referring to Figure 8 , which shows the flowchart of a water purifier monitoring and processing method provided by an embodiment of the present application Figure 6 , step S605 specifically includes the following steps S701 - S702:

[0096] Step S701: When the user is in the first water usage state, recommend the alternative solutions whose second flow rate value is greater than or equal to the first flow rate value and whose estimated usage durations are before the preset ranking.

[0097] In the above steps, when the user is in a state of relatively high water consumption, the server will recommend to the user a to-be-selected solution whose second flow value is greater than or equal to the first flow value and whose estimated usage duration is among the top in the preset ranking.

[0098] Specifically, in this technical solution, the preset ranking is the top three. Since the server will obtain multiple to-be-selected solutions based on the filter element selection condition information selected by the user, the server will screen the multiple to-be-selected solutions, select the to-be-selected solutions whose second flow value is greater than or equal to the first flow value, and recommend the top three of the remaining to-be-selected solutions.

[0099] It should be noted that if there is no matching to-be-selected solution after the server's screening, the server will ask the user to re-select the filter element selection condition information, and based on the newly selected filter element selection condition information by the user, perform screening and recommendation again.

[0100] Step S702: When the user is in the second water usage state, recommend the to-be-selected solutions whose estimated usage duration is among the top in the preset ranking.

[0101] In the above steps, when the user is in a state of relatively low water consumption, the server will recommend the to-be-selected solutions whose estimated usage duration is among the top in the preset ranking.

[0102] Specifically, in this technical solution, multiple to-be-selected solutions will be obtained based on the filter element selection condition information selected by the user, and the server will screen the multiple to-be-selected solutions and recommend the top three of the remaining to-be-selected solutions.

[0103] It should be noted that since the user's water consumption is relatively low, the server will comprehensively judge from two aspects, namely price and estimated usage duration, whether there is a replacement solution for the current filter element among the to-be-selected solutions.

[0104] Step S107: When the water purifier is in an abnormal working state, recommend filter element models to the user based on the water usage state and multiple to-be-selected solutions.

[0105] In the above steps, when the water purifier is in an abnormal working state, the server will recommend filter element models to the user according to the user's water usage state and multiple to-be-selected solutions.
