Description

Technical Field

[0001] The present application relates to the field of water purifiers, and in particular to a method, device, and storage medium for monitoring the life of a water purifier filter element. Background Art

[0002] With the development of science and technology and people's pursuit of quality of life, the use of water purifiers has become more and more common. The filter element is an important component of the water purifier to achieve water purification. The filter element needs to be replaced after its life span is reached, otherwise the water quality of the water purifier will not meet the standards. The length of time the filter element is used, the amount of water produced and even the quality of the filtered water will affect the life of the filter element. However, the life of the filter element is basically determined by the user's subjective observation of the water output speed of the filter element to determine whether the filter element has expired. However, different users using different installation techniques will cause differences in the life of the filter element.

[0003] When users subjectively observe whether to replace the filter element, they often make inaccurate judgments about the filter element life. For example, the filter element life has not yet expired, and it is wasted if it is directly replaced; or the filter element has expired but the user believes it has not expired, resulting in substandard water quality; or the filter element has not been used for a long time, resulting in structural aging and damage. If it is used at this time, the water output of the filter element will be large, which may easily make the user believe that the filter element life has not expired. Summary of the Invention

[0004] In order to improve the problem that it is difficult for users to subjectively judge whether the filter cartridge life has expired, the present application provides a method, device and storage medium for monitoring the life of a water purifier filter cartridge.

[0005] This application provides a method, device, and storage medium for monitoring the life of a water purifier filter element, which adopts the following technical solutions:

[0006] A method for monitoring the life of a water purifier filter element, the method comprising:

[0007] S1. Assigning initial values to basic operating parameters based on characteristic data of a target filter element. The basic operating parameters include the remaining amount of the filter element, the total water production amount of the filter element, the total usage time of the filter element, and the start operating time of the target filter element;

[0008] S2. Within a preset time period, determine a water production capacity attenuation rate value based on the total water production capacity value of the filter element and by real-time acquisition of the water production flow rate value of the target filter element, and determine a remaining time attenuation rate value based on the total filter element usage time value and the start working time of the target filter element, and update the filter element remaining capacity value according to the water production capacity attenuation rate value and the remaining time attenuation rate value;

[0009] S3. Confirm whether the updated filter element remaining value is greater than a preset remaining value threshold, and if the filter element remaining value is greater than the remaining value threshold, return to step S2; and if the filter element remaining value is not greater than the remaining value threshold, trigger an early warning operation to send a filter element life expiration reminder message to the user.

[0010] By adopting the above technical solution, the filter element remaining value is updated by calculating the water production attenuation rate value and the remaining time attenuation rate value, so that when the water production of the filter element is about to reach the maximum water production, the filter element remaining value will reach the remaining value threshold, or when the use time of the filter element is about to reach the maximum time, the filter element remaining value will also reach the remaining value threshold. By collecting and calculating, more accurate results are obtained, which reduces the inaccuracy caused by the user's subjective observation, allowing the user to replace the filter element after the life of the filter element expires, reducing the probability of increased costs due to early replacement or deterioration of water quality due to late replacement, and reducing the filter element idle for a long time. The low amount of water leads to the probability that the user can continue to use the filter element; the life of the filter element is displayed in the form of data, the remaining water production volume and the remaining usage time are unified into the remaining value of the filter element, and the two variables are calculated and unified into one variable, which greatly facilitates the subsequent judgment of the filter element life and user observation. The user can understand the life of the filter element by observing the remaining value of the filter element, which facilitates calculation and observation; at the same time, the flow rate value is collected in real time for calculation, and the life of the filter element in different environments is reflected in real time, which allows users to observe the status of the filter element more intuitively, ensuring that the filter element is used by the user under good conditions.

[0011] Optionally, the method further includes:

[0012] When the remaining amount value of the filter element is greater than the remaining amount threshold, before returning to step S2, the total water production value of the filter element is compensated according to the water quality parameters of the water source used by the target filter element.

[0013] By adopting the above technical solution, the total water production value of the filter element is compensated according to different water qualities, thereby reducing the probability that the total water production value of the filter element will be reduced due to excessive filtration pressure of the filter element due to poor water quality in the external environment, or the total water production value of the filter element will be increased due to lower filtration pressure of the filter element due to good water quality in the external environment. This makes the calculation of the remaining value of the filter element more accurate, and the judgment of the filter element life more accurate.

[0014] Optionally, the warning operation includes:

[0015] S40, collecting a water temperature value of the water source used by the target filter element and a flow rate value of water produced by the target filter element, and determining a flow rate quantitative value based on the water temperature value and the flow rate value;

[0016] S41, determining a filter element usage time value according to the starting working time, and determining a remaining time quantitative value based on the filter element usage time value and the total filter element usage time value;

[0017] S42. Update the filter element remaining value according to the flow rate quantitative value and the remaining time quantitative value, and send the filter element life expiration reminder information to the customer when the updated filter element remaining value is less than the preset warning threshold value; otherwise, return to step S40.

[0018] By adopting the above technical solution, when the remaining value of the filter element is less than the remaining value threshold, the algorithm is switched to the early warning operation, and the flow rate value and the water temperature value are used for calculation. The flow rate value is used to more accurately calculate the filter element life. Adding the outlet water temperature value to the calculation reduces the influence of the ambient temperature on the filter element life, and reduces the probability that the remaining water production value algorithm will show errors in the filter element life due to the influence of external environmental factors in the calculation of the remaining water production value, making the calculation more accurate and reducing the error; the filter element is used to calculate the service life that the manufacturing material used for the filter element can withstand by the filter element through the use time value, and also reduces the probability of misjudging the filter element life when the water production volume is small but the use time is long; the remaining time quantitative value and the flow rate quantitative value are unified into the filter element remaining value, and then the filter element remaining value is compared with the early warning threshold for judgment, which further improves the accuracy of the judgment and facilitates direct observation of the filter element remaining value to understand the filter element life.

[0019] Optionally, the warning operation further includes:

[0020] After sending the filter cartridge life expiration reminder information to the user, return to step S40, and if the updated filter cartridge remaining value is not greater than the preset shutdown threshold, confirm whether to activate a new filter cartridge, and if it is confirmed that the new filter cartridge has been activated, return to step S1, and if it is not confirmed that the new filter cartridge has been activated, wait for a preset time period and confirm again whether the new filter cartridge has been activated, and if it is still not confirmed that the new filter cartridge has been activated, directly shut down the water purifier where the target filter cartridge is located.

[0021] By adopting the above technical solution, after the filter element expires and the user does not replace the filter element with a new one, in order to reduce the probability of water quality degradation caused by continuing to produce water after the filter element expires, the water purifier will be locked for protection, which also protects the user.

[0022] Optionally, determining a water production capacity attenuation rate value based on the total water production capacity value of the filter element and by real-time acquisition of a water production flow rate value of the target filter element, determining a remaining time attenuation rate value based on the total filter element usage time value and the start working time of the target filter element, and updating the filter element remaining capacity value according to the water production capacity attenuation rate value and the remaining time attenuation rate value includes:

[0023] The flow rate value of the target filter element producing water is collected in real time to determine a unit water production value of the filter element within the time period, wherein the unit water production value of the filter element indicates the amount of water produced by the filter element within the time period, and the usage time value of the filter element is determined based on the starting working time;

[0024] Determine a water production capacity attenuation rate value based on the filter element unit water production value, the filter element total water production value, and the filter element remaining capacity value; and determine a remaining time attenuation rate value based on the filter element usage time value, the filter element total usage time value, and the filter element remaining capacity value;

[0025] The filter element remaining value is updated according to the water production attenuation rate value and the remaining time attenuation rate value.

[0026] By adopting the above technical solution, the remaining water production value of the filter element is calculated by the total water production value of the filter element and the remaining water production value of the filter element, that is, how much water the filter element can still produce. Then, the water production attenuation rate value within the time period is calculated by the unit water production value of the filter element within the time period, the remaining water production value of the filter element, and the remaining water production value of the filter element. This represents the ratio of the water production value generated by the filter element within the current time period to the remaining water production value of the filter element, thereby realizing the calculation of the usage of the filter element itself. The remaining usage time value of the filter element is calculated by the total usage time value of the filter element and the used time value of the filter element, that is, how much time the filter element can still be used. Then, the remaining time attenuation rate value within the time period is calculated by the time value of the time period, the remaining water production value of the filter element, and the remaining usage time value of the filter element. This represents the ratio of the time value of the filter element used within the current time period to the remaining usage time value of the filter element, thereby realizing the calculation of the usage of the filter element itself. When the remaining life of the filter element is long, this algorithm is more accurate and reduces the load on the server.

[0027] Optionally, compensating the total water production value of the filter element according to the water quality parameters of the water source used by the target filter element includes:

[0028] A compensation coefficient is determined based on the water quality parameters of the water source used by the target filter element, a compensation value is determined based on the compensation coefficient and the total water production value of the filter element, a fluctuation number value of the water quality parameter is determined based on the continuous water quality parameters and a preset fluctuation threshold value, a compensation point value is determined based on the fluctuation number value, the remaining value threshold value and the initial filter element remaining value, the number of parts into which the compensation value is divided is determined based on the fluctuation number value, each time the filter element remaining value drops to a new compensation point value, the total water production value of the filter element is compensated based on the divided compensation value, and the total water production value of the filter element for the next time period is determined based on the compensated total water production value of the filter element.

[0029] By adopting the above technical solution, the compensation value is adapted to the fluctuation of the water quality of the external environment through the fluctuation number value. When the water quality of the external environment changes through multiple compensations, the compensation value and the number of compensations change accordingly, which reduces the probability of deviation in the calculation of the remaining value of the filter element due to the previous compensation value when the water quality of the external environment changes. At the same time, by performing compensation a certain number of times instead of compensation in each cycle, the number of calculations during compensation is greatly reduced, thereby reducing the amount of calculation and the pressure on the server. The same server performance and storage space can carry and calculate more filter elements, reducing computing costs.

[0030] Optionally, determining the flow rate quantitative value based on the water temperature value and the flow rate value includes:

[0031] The flow rate values and water temperature values at multiple consecutive time points are respectively obtained, the end values of the flow rate values and the water temperature values are removed, and the average flow rate value and the average water temperature value are respectively determined based on the flow rate values after removing the end values and the water temperature values after removing the end values, and the flow rate quantitative value is determined based on the average value of the average flow rate values and the average water temperature values.

[0032] By adopting the above technical solution, the maximum and minimum values in the flow rate and water temperature values are removed, which reduces the probability of extreme factors or error factors affecting the calculation. By calculating the average value, the flow rate and water temperature values are made more stable, accurate and reference-based when they are used in the calculation of the flow rate quantitative value. This greatly reduces the probability of mis-insertion in the calculation caused by the sudden entry of high and low temperature objects detected by the sensor, resulting in a change in the water temperature value, or a small amount of granular impurities appearing in the incoming water, causing the flow rate to suddenly decrease and then recover, resulting in a change in the flow rate value. This reduces the impact of sudden factors that are not reference-based on the calculation results.

[0033] Optionally, a device for monitoring the life of a water purifier filter element includes an initialization unit, a filter element remaining value update unit, and an early warning operation triggering unit:

[0034] The initialization unit is used to assign initial values to basic operating parameters according to the characteristic data of the target filter element, and the basic operating parameters include the remaining amount of the filter element, the total water production value of the filter element, the total usage time of the filter element, and the starting working time of the target filter element;

[0035] The filter element remaining value updating unit is used to perform a filter element remaining value updating operation within a preset time period, and the filter element remaining value updating operation includes: determining a water production capacity attenuation rate value based on the total water production capacity value of the filter element and by real-time acquisition of the water production flow rate value of the target filter element, and determining a remaining time attenuation rate value based on the total use time value of the filter element and the start working time of the target filter element, and updating the filter element remaining value according to the water production capacity attenuation rate value and the remaining time attenuation rate value, and transmitting the updated filter element remaining value to the early warning operation triggering unit;

[0036] The early warning operation triggering unit is used to confirm whether the updated filter element remaining value is greater than the preset remaining value threshold after receiving the updated filter element remaining value, and when the filter element remaining value is greater than the remaining value threshold, trigger the filter element remaining value updating unit to perform the filter element remaining value updating operation within the next preset time period; and when the filter element remaining value is not greater than the remaining value threshold, trigger the early warning operation to send a filter element life expiration reminder message to the user.

[0037] By adopting the above technical solution, data is collected through the filter element remaining value update unit, and the collected data and the basic working parameters assigned initial values are calculated to obtain the filter element remaining value representing the remaining life of the filter element. The early warning operation unit is then used to remind the user based on the filter element remaining value, thereby realizing automated judgment, facilitating the user's operation judgment, and improving the accuracy of the judgment.

[0038] Optionally, a computer-readable storage medium stores a computer program that can be loaded and executed by a processor, wherein the computer program can implement the method for monitoring the life of a water purifier filter element.

[0039] By adopting the above technical solution, the program executed by the processor is stored in a computer-readable storage medium.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. It can realize real-time observation of the filter element life, and allow users to observe the status of the filter element more intuitively, ensuring that the filter element is used by users in good conditions.

[0042] 2. Unify multiple data indicating the life of the filter element into the remaining value of the filter element to facilitate calculation and observation.

[0051] The following is combined with Figure 1-6 This application is described in further detail.

[0052] The present application discloses a method, device and storage medium for monitoring the life of a water purifier filter element. Figure 1 , a method for monitoring the life of a water purifier filter element includes:

[0053] S1. Assign initial values to basic working parameters according to characteristic data of the target filter element. The basic working parameters include the filter element remaining value Z, the filter element total water production value Y, the filter element total usage time value T, and the starting working time of the target filter element.

[0054] S2. Within a preset time period t, the water production attenuation rate value M is determined based on the total water production value Y of the filter element and by real-time collection of the flow rate value S of the target filter element water production, and the remaining time attenuation rate value N is determined based on the total usage time value Y of the filter element and the starting working time of the target filter element, and the filter element remaining value Z is updated according to the water production attenuation rate value M and the remaining time attenuation rate value N.

[0055] S3. Confirm whether the updated filter element remaining value Z is greater than the preset remaining value threshold A, and if the filter element remaining value Z is greater than the remaining value threshold A, return to step S2; and if the filter element remaining value Z is not greater than the remaining value threshold A, trigger an early warning operation to send a filter element life expiration reminder message to the user.

[0056] Specifically:

[0057] Reference Figure 2 and Figure 3 , S1 is the filter element installation activation, IOT records the filter element activation time, IOT assigns initial values to the basic working parameters according to the characteristic data of the target filter element (filter element ID data), the basic working parameters include the filter element remaining value Z, the total water production value X, the total filter element usage time value T and the starting working time of the target filter element, the filter element remaining value Z is initialized to Z = 100%, the starting working time of the target filter element is the filter element activation time, and the filter element total water production value Y = X.

[0058] In this embodiment, the filter element remaining value Z can be displayed to the user through the display, and the filter element activation time recorded by the IOT can be used as the starting point of the filter element usage time, that is, the total filter element usage time value is counted at the filter element activation time.

[0059] Step S2 includes S21, S22, and S23:

[0060] Reference Figure 2 and Figure 3 S21. Real-time collection of the target filter element water flow rate value S to determine the filter element unit water production value L within the preset time period t. The filter element unit water production value indicates the water production amount generated by the filter element within the time period t. The water production attenuation rate value M is determined based on the filter element unit water production value L, the filter element total water production value Y, and the filter element remaining quantity value Z.

[0061] In this embodiment, the flow rate value S of the water outlet of the filter element can be detected and collected in real time by a flow meter. The time period is t. Assume that one day is a time period t, that is, the flow rate value S collected for the past whole day is obtained at 24:00 every day, and the average value S′ of the flow rate value S for one day is calculated and multiplied by the time of one day to obtain the unit water production value L of the filter element today, that is, L=S′*t.

[0062] Then obtain the filter element unit water production value L collected in the previous time period t and add them together to obtain the filter element water production value L ′ The remaining value Z of the filter element is a percentage value, and the unit water production value L of the filter element, the total water production value Y of the filter element, and the water production value L of the filter element are ′ , the filter element residual value Z is used to calculate the water production attenuation rate value M;

[0063]

[0064] For example: the filter element unit water production value L is 1 ton, the filter element total water production value Y is 100 tons, the filter element has water production value L ′ Take 0 tons and the filter element remaining value Z as 100%, then

[0065] In the next cycle, since the unit water production value L of the filter element in the previous time period t becomes the water production value L of the filter element in the next time period t ′ Therefore, the unit water production value L of the filter element is 1 ton, the total water production value Y of the filter element is 100 tons, and the water production value L of the filter element is ′ Take 1 ton, the filter element remaining value Z is the filter element remaining value Z calculated after the previous time period t, so the filter element remaining value Z is 99%, then

[0066] The water production attenuation rate value M represents the proportion of the filter element unit water production value L in the filter element remaining value Z in the current time period t.

[0067] Reference Figure 2 and Figure 3 S22: Determine the filter element usage time value t based on the starting working time. ′ , based on the filter element usage time value t ′ , the total usage time value T of the filter element, and the remaining value Z of the filter element determine the remaining time decay rate value N.

[0068] t′=∑t;

[0069] For example: the time period t is 1 day, and the filter element has been used for a time value of t ′ Take 0 days, the total filter element usage time value T as 100 days, and the filter element remaining value Z as 100%, then

[0070] In the next time period t, since the time period t of the previous period has passed, it becomes the used time value t of the next period ′ , so the filter element has been used for time value t ′ Take 1 day, the total filter element usage time T is 100 days, and the filter element remaining value Z is the filter element remaining value Z calculated after the previous time period t. Therefore, the filter element remaining value Z is 99%, then

[0071] The remaining time decay rate value N represents the proportion of the time period t consumed in this cycle to the remaining amount Z of the filter element.

[0072] Reference Figure 2 and Figure 3, S23. Update the remaining filter element quantity value Z according to the water production attenuation rate value M and the remaining time attenuation rate value N;

[0073] If M > N, then P = M; if M ≤ N, then P = N; Z = Z - P;

[0074] Example: The water production attenuation rate value M is taken as 1.2%, the remaining time attenuation rate value N is taken as 1%, and the remaining filter element quantity value Z is taken as 100%. Then M = 1.2% > N = 1%, so P = M = 1.2%, and Z = Z - P = 100% - 1.2% = 98.8%.

[0075] In the next cycle, the water production attenuation rate value M is taken as 0.8%, the remaining time attenuation rate value N is taken as 1%, and the remaining filter element quantity value Z is the remaining filter element quantity value Z calculated in the previous time period t. Therefore, the remaining filter element quantity value Z is 98.8%. Then M = 0.8% < N = 1%, so P = N = 1%, and Z = Z - P = 98.8% - 1% = 97%.

[0076] Step S3 includes S31, S32, S33:

[0077] Refer to Figure 2 And Figure 3 , S31. Confirm whether the updated remaining filter element quantity value Z is greater than the preset remaining quantity threshold A.

[0078] The user can adjust and set the remaining quantity threshold A according to conditions such as the filter element model and usage environment.

[0079] Refer to Figure 2 And Figure 3 , S32. When the remaining filter element quantity value Z is not greater than the remaining quantity threshold A, trigger a warning operation.

[0080] Refer to Figure 2 And Figure 4 , S40. Determine the quantity of the water temperature value C of the water source used by the target filter element to be collected and the quantity of the water production flow rate value S of the target filter element based on the preset reference quantity value, determine the quantity of the end values of the flow rate value S to be removed and the quantity of the end values of the water temperature value C to be removed based on the preset error quantity value, determine the average flow rate value S″ and the average water temperature value C′ respectively based on the several flow rate values S after removing the end values and the several water temperature values C after removing the end values, determine the temperature coefficient C″ by looking up the table based on the average water temperature value C′, determine the net flow rate value S″′ based on the temperature coefficient C″ and the average flow rate value S″, and determine the flow rate quantification value W by looking up the table based on the net flow rate value S″′;

[0081]

[0082] For example, if the remaining amount threshold value A is 3%, then when the filter element remaining amount value Z is less than or equal to 3%, the warning operation is triggered. After the warning operation is triggered, steps S21, S22, and S23 will no longer be executed.

[0083] In this embodiment, a water temperature detection sensor can be used to detect the water temperature. The relationship table between the flow rate quantitative value W and the net flow rate value S″′ is: 1350mL / min≤S″′≤1399mL / min, W=1.8%; 1300mL / min≤S″′≤1349mL / min, W=1.5%; S″′≤1000mL / min, W=0%; the relationship table between the average water temperature value C′ and the temperature coefficient C″ is: 18℃≤C′≤27℃, C″=1; 29℃≤C′, C″=1.1; the reference value is 60, the error value is 5, the most recent 60 flow rate values S and water temperature values C are counted, the 5 maximum values are removed, the 5 minimum values are removed, and the remaining 50 flow rate values S and water temperature values C are averaged to obtain the average flow rate value S″ and the average water temperature value C′;

[0084] If the average flow rate S" is 1350 mL / min and the average water temperature C' is 19°C, the temperature coefficient C" = 1 is obtained from the table. Looking up the table, we get W=1.8%.

[0085] If the average flow rate S″ is 1450 mL / min and the average water temperature C′ is 33°C, the temperature coefficient C″ is 1.1. Looking up the table, we get W=1.5%.

[0086] If the average flow rate S" is 999 mL / min and the average water temperature C' is 19°C, the temperature coefficient C" = 1 is obtained from the table. Looking up the table, we get W=0%.

[0087] The flow rate quantitative value W represents the relationship between the current water flow rate of the filter element under the influence of water temperature and the water flow rate of the full-life filter element at the optimal working water temperature.

[0088] Reference Figure 2 and Figure 4 S41, determining the filter element usage time value t' according to the start working time, periodically determining the filter element remaining time value t" based on the filter element usage time value t' and the total filter element usage time T, and determining the remaining time quantitative value V based on the filter element remaining time value t" and the total filter element usage time value T;

[0089] t′=∑t,t″=Tt ′ , For example: If the filter element has been used for 300 days, the total use time T is 365 days, and the remaining time is

[0090] If the used time value t' of the filter element is taken as 320 days, the total service time T of the filter element is taken as 365 days, and the remaining time quantitative value

[0091] If the used time value t' of the filter element is taken as 300 days, the total service time T of the filter element is taken as 340 days, and the remaining time quantitative value

[0092] Refer to Figure 2 And Figure 4 , S42. Update the remaining amount value Z of the filter element according to the flow rate quantitative value W and the remaining time quantitative value V, and when the updated remaining amount value Z of the filter element is less than the preset warning threshold Q, send the reminder information that the filter element life has expired to the customer; otherwise, return to step S40.

[0093] Example: If the flow rate quantitative value W is taken as 1.8%, and the remaining time quantitative value V is taken as 17.8%, then W < V, and Z = W = 1.8%.

[0094] If the flow rate quantitative value W is taken as 1.5%, and the remaining time quantitative value V is taken as 12.3%, then W < V, and Z = W = 1.5%.

[0095] If the flow rate quantitative value W is taken as 0%, and the remaining time quantitative value V is taken as 6.8%, then W < V, and Z = W = 0%.

[0096] And in this embodiment, the remaining amount value Z of the filter element after the warning operation can only decrease. If the remaining amount value Z of the filter element increases, the remaining amount value Z when it has not increased is still displayed.

[0097] If the warning threshold Q is taken as 0%, and the remaining amount value Z of the filter element is taken as 1.8%, then Q < Z, and return to step S40.

[0098] If the warning threshold Q is taken as 0%, and the remaining amount value Z of the filter element is taken as 1.5%, then Q < Z, and return to step S40.

[0099] If the warning threshold Q is taken as 0%, and the remaining amount value Z of the filter element is taken as 0%, then Q = Z. In this embodiment, the reminder information that the filter element life has expired can be output to the user through text messages or software messages to remind that the filter element has expired.

[0100] Refer to Figure 4, S43. After sending the filter cartridge life expiration reminder information to the user, return to step S40, and when the updated filter cartridge remaining value Z is not greater than the preset shut-off threshold B, confirm whether to activate a new filter cartridge, and when it is confirmed that the new filter cartridge has been activated, return to step S1, and when it is not confirmed that the new filter cartridge has been activated, wait for a preset time period and confirm again whether to activate the new filter cartridge, and when it is still not confirmed that the new filter cartridge has been activated, directly shut down the water purifier where the target filter cartridge is located.

[0101] For example: the shutdown threshold B is 0%, the preset time period is seven time periods t, and the time period t is 1 day, that is, the preset cycle is seven times. If the user does not replace the filter element and reset the initial filter element data after the filter element remaining value Z is equal to 0%, that is, seven days after the filter element expires, the machine will be automatically locked.

[0102] Reference Figure 2 and Figure 5 S5. When the filter element remaining value Z is greater than the remaining value threshold A, the compensation coefficient N is determined based on the water quality parameter of the water source used by the target filter element, the compensation value is determined based on the compensation coefficient N and the total water production value X, the fluctuation number value n of the water quality parameter is determined based on the continuous water quality parameters and the preset fluctuation threshold, the compensation point value is determined based on the fluctuation number value n, the remaining value threshold A and the initial filter element remaining value Z, the number of parts of the compensation value is determined based on the fluctuation number value n, each time the filter element remaining value Z drops to a new compensation point value, the filter element total water production value Y is compensated based on the divided compensation value, and the filter element total water production value Y for the next time period is determined based on the compensated filter element total water production value Y, and the process returns to step S21.

[0103] For example: If the value of the water quality parameter continuously rising or falling is greater than the fluctuation threshold, it means that the water quality of the water entering the filter element has changed, and the total water production value Y of the filter element needs to be compensated to correct the filter element life. Therefore, every time the value of the water quality parameter continuously rises or falls greater than the fluctuation threshold, the fluctuation number value n is increased by 1. The water quality parameter data in the calculation of the fluctuation number value n comes from the overall situation data when the previous filter element was used, and the water quality parameter in the compensation value calculation is collected in real time.

[0104] In this embodiment, a TDS water quality detector can be used to detect the water quality of the water source used by the target filter element. The remaining amount threshold value A is 3%, and the fluctuation number value n is 3. Then, the number of compensation points is three. The three compensation points divide the portion of the initial filter element remaining amount value Z that is greater than the remaining amount threshold value A equally, that is, the portion from 3% to 100% is divided into four equal parts. The three compensation point values are 27.25%, 51.5%, and 75.75% respectively.

[0105]

[0106] Whenever the filter element remaining value Z drops to 27.25%, 51.5%, 75.75% for the first time, the total water production value Y of the filter element is compensated by one

[0107] The implementation principle of a method for monitoring the life of a water purifier filter element in an embodiment of the present application is as follows: after the filter element is activated, the user inputs initial data, the IOT detects the water flow rate value S, water temperature value C, water quality parameters, etc., and periodically calculates the filter element remaining value Z. If the filter element remaining value Z is greater than the remaining threshold value A set by the user, the cycle continues. If the filter element remaining value Z is less than or equal to the remaining threshold value A set by the user, it indicates that the filter element life is running out and an early warning operation is triggered. At this time, the filter element remaining value Z is more accurately calculated and obtained by looking up the table through the flow rate value. If the filter element remaining value Z is greater than the early warning threshold value Q, the cycle continues within the early warning operation. If the filter element remaining value Z is less than or equal to the early warning threshold value Q, the user is reminded that the filter element service life has expired.
