[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.
[0027] Figure 1 This is a flowchart illustrating a method for determining filter cartridge lifespan provided in this application. This method can be executed by the filter cartridge lifespan determination device provided in this application, which can be implemented using software and / or hardware. In a specific embodiment, the device can be integrated into a water purification device, which can be a water purifier. The following embodiments will illustrate this using the integration of the device into a water purification device as an example. (Reference) Figure 1 The method may specifically include the following steps:
[0028] Step 101: Obtain the impurity content of the water effluent, the water flow rate, and the booster pump current value from the water purification equipment.
[0029] Among them, the effluent impurity content is the total dissolved solids (TDS) value of the pure water flowing out of the water purification equipment, the effluent flow rate is the pure water flow rate of the pure water flowing out of the water purification equipment, and the booster pump current value is the working current value of the booster pump.
[0030] Specifically, when the water purification equipment is working, it can detect in real time the impurity content of the water output, the water flow rate, and the current value of the booster pump.
[0031] For example, the water purification equipment includes an outlet water impurity content detection sensor to obtain the outlet water impurity content; the water purification equipment includes an outlet water flow detection sensor to obtain the outlet water flow; and the water purification equipment includes a booster pump current value detection sensor to obtain the booster pump current value.
[0032] Step 102: Determine the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value.
[0033] Optionally, the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value are determined based on a first preset functional relationship, a second preset functional relationship, and a third preset functional relationship. The first preset functional relationship includes the functional relationship between the effluent impurity content and the corresponding actual lifespan value; the second preset functional relationship includes the functional relationship between the effluent flow rate and the corresponding actual lifespan value; and the third preset functional relationship includes the functional relationship between the booster pump current value and the corresponding actual lifespan value.
[0034] Specifically, after obtaining the impurity content of the water purifier's output water, a first preset function relationship is queried, and the actual lifespan value corresponding to the measured impurity content of the output water is obtained based on the first preset function relationship; after obtaining the output water flow rate, a second preset function relationship is queried, and the actual lifespan value corresponding to the output water flow rate is obtained based on the second preset function relationship; after obtaining the booster pump current value of the water purifier, a third preset function relationship is queried, and the actual lifespan value corresponding to the booster pump current value is obtained based on the third preset function relationship.
[0035] For example, the first preset functional relationship is as follows: Figure 2 The function graph shown has the following second preset function relationship: Figure 3 The function graph shown has the following third preset function relationship: Figure 4 The function graph shown is illustrated below. For example, when the measured effluent impurity content is 50 mg / L, the actual lifespan corresponding to the effluent impurity content is approximately 0.9; when the measured effluent flow rate is 1 L / min, the actual lifespan corresponding to the effluent impurity content is approximately 0.5; and when the measured booster pump current is 2 A, the actual lifespan corresponding to the booster pump current is approximately 1.
[0036] Step 103: Obtain the preset weights corresponding to the impurity content of the effluent, the effluent flow rate, and the booster pump current value.
[0037] The preset weights for the impurity content of the effluent, the effluent flow rate, and the booster pump current value are weight coefficients pre-set by the manufacturer.
[0038] Specifically, preset weights are obtained for the effluent impurity content, effluent flow rate, and booster pump current value. The preset weight for effluent impurity content is 0.3, for effluent flow rate it is 0.5, and for booster pump current value it is 0.2.
[0039] Step 104: Determine the remaining lifespan of the filter element of the water purification equipment based on the actual lifespan values corresponding to the impurity content, flow rate, and booster pump current value of the effluent, and the preset weights corresponding to the impurity content, flow rate, and booster pump current value of the effluent, respectively.
[0040] Optionally, the lifespan coefficient is obtained by multiplying the actual lifespan values corresponding to the impurity content, flow rate, and booster pump current value of the effluent, and summing the preset weights corresponding to the impurity content, flow rate, and booster pump current value of the effluent, respectively.
[0041] Specifically, after determining the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, and the preset weights corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, the lifespan coefficient is determined by multiplying the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, and the preset weights corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, and then summing them.
[0042] A=0.5×X+0.3×Y+0.2×Z Formula 1
[0043] Where A represents the lifespan coefficient, X represents the actual lifespan value corresponding to the outflow rate, Y represents the actual lifespan value corresponding to the impurity content in the outflow, and Z represents the actual lifespan value corresponding to the booster pump current.
[0044] Optionally, the remaining lifespan of the filter element can be calculated based on the lifespan factor and the preset lifespan value of the filter element.
[0045] The preset lifespan value of the filter element is a fixed lifespan value preset at the factory.
[0046] Specifically, after determining the life coefficient of the filter element, the remaining life of the filter element is calculated based on the life coefficient and the preset life value of the filter element. That is, the remaining life of the filter element can be determined according to Formula 2.
[0047] F = A × K Formula 2
[0048] Where F represents the remaining life of the filter element, A represents the life coefficient, and K represents the preset life value of the filter element.
[0049] The solution proposed in this application obtains the impurity content of the effluent, the flow rate of the effluent, and the current value of the booster pump from the water purification equipment; determines the actual lifespan values corresponding to the impurity content, flow rate, and booster pump current value; obtains the preset weights corresponding to the impurity content, flow rate, and booster pump current value; and determines the remaining lifespan of the filter element of the water purification equipment based on the actual lifespan values and preset weights corresponding to the impurity content, flow rate, and booster pump current value of the effluent, flow rate, and booster pump current value. In other words, the solution proposed in this application can determine the remaining lifespan of the filter element of the water purification equipment by obtaining the actual lifespan values corresponding to the impurity content, flow rate, and booster pump current value of the effluent, combined with the corresponding preset weights. It comprehensively considers multiple factors affecting the lifespan of the filter element and uses the actual lifespan values as calculation data, thus improving the accuracy of filter element lifespan calculation and allowing the filter element to be used more effectively.
[0050] Figure 5 This is another flowchart illustrating the filter life determination method provided in this application, as shown below. Figure 5 As shown, the method may include the following steps:
[0051] Step 201: Obtain the impurity content of the water purifier, the water flow rate, and the booster pump current value.
[0052] Step 202: Based on the effluent impurity content, query the first preset function relationship to obtain the actual lifespan value corresponding to the effluent impurity content.
[0053] The first preset functional relationship includes the functional relationship between the effluent impurity content and the actual lifespan value corresponding to the effluent impurity content. For example, the first preset functional relationship can be a function graph or a functional formula.
[0054] Specifically, after obtaining the impurity content of the water purifier's output water, the system queries a preset first function relationship and obtains the actual lifespan value corresponding to the measured output water impurity content based on the first preset function relationship.
[0055] For example, the first preset functional relationship is as follows: Figure 2 The function graph shown indicates that when the measured effluent impurity content is 0 mg / L, the actual lifespan corresponding to the measured effluent impurity content is approximately 1; when the measured effluent impurity content is 25 mg / L, the actual lifespan corresponding to the measured effluent impurity content is approximately 0.95; when the measured effluent impurity content is 50 mg / L, the actual lifespan corresponding to the measured effluent impurity content is approximately 0.9; when the measured effluent impurity content is 80 mg / L, the actual lifespan corresponding to the measured effluent impurity content is approximately 0.6; and when the measured effluent impurity content is 99 mg / L, the actual lifespan corresponding to the measured effluent impurity content is approximately 0.
[0056] Step 203: Obtain the actual lifespan value corresponding to the water flow rate by querying the second preset function relationship based on the water flow rate.
[0057] The second preset functional relationship includes the functional relationship between the water flow rate and the actual lifespan value corresponding to the water flow rate. For example, the second preset functional relationship can be a function graph or a functional expression.
[0058] Specifically, after obtaining the outflow rate, the system queries the second preset function relationship and obtains the actual lifespan value corresponding to the outflow rate based on the measured outflow rate and the second preset function relationship.
[0059] For example, the second preset functional relationship is as follows: Figure 3 The function graph shown indicates that when the measured outflow rate is 2 L / min, the actual lifespan corresponding to the impurity content in the outflow is approximately 1; when the measured outflow rate is 1 L / min, the actual lifespan corresponding to the impurity content in the outflow is approximately 0.5; when the measured outflow rate is 0.6 L / min, the actual lifespan corresponding to the impurity content in the outflow is approximately 0.25; and when the measured outflow rate is 0 L / min, the actual lifespan corresponding to the impurity content in the outflow is approximately 0.
[0060] Step 204: Based on the booster pump current value, query the third preset function relationship to obtain the actual life value corresponding to the booster pump current value.
[0061] The third preset functional relationship includes the functional relationship between the booster pump current value and the actual life value corresponding to the booster pump current value. For example, the third preset functional relationship can be a function graph or a function formula.
[0062] Specifically, after obtaining the current value of the booster pump of the water purification equipment, the third preset function relationship is queried, and the actual life value corresponding to the booster pump current value is obtained based on the measured booster pump current value and the third preset function relationship.
[0063] For example, the third preset function relationship is as follows: Figure 4 The function graph shown indicates that when the measured booster pump current is 0A, the actual lifespan of the booster pump is approximately 1; when the measured booster pump current is 1A, the actual lifespan is approximately 1; when the measured booster pump current is 2A, the actual lifespan is approximately 1; when the measured booster pump current is 3A, the actual lifespan is approximately 0.85; and when the measured booster pump current is 3.5A, the actual lifespan is approximately 0.
[0064] Step 205: Obtain the preset weights corresponding to the impurity content of the effluent, the effluent flow rate, and the booster pump current value.
[0065] Specifically, the preset weights for obtaining the water impurity content, water flow rate, and booster pump current value are 0.3, 0.5, and 0.2, respectively.
[0066] Step 206: Multiply the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value by the preset weights corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, and then sum them to obtain the lifespan coefficient.
[0067] Specifically, after determining the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, and the preset weights corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, the lifespan coefficient can be obtained by multiplying the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, and the preset weights corresponding to the effluent impurity content, effluent flow rate, and booster pump current value, and then summing them.
[0068] For example, when the actual lifespan values corresponding to the effluent impurity content, effluent flow rate, and booster pump current value are determined to be 0.5, 0.4, and 0.3 respectively, the lifespan coefficient is 0.41 according to Formula 1.
[0069] Step 207: Calculate the remaining lifespan of the filter element based on the lifespan factor and the preset lifespan value of the filter element.
[0070] Specifically, after determining the life coefficient of the filter element, the remaining life of the filter element is calculated by multiplying the life coefficient by the preset life value of the filter element.
[0071] Step 208 shows the remaining lifespan of the water purifier's filter cartridge.
[0072] Specifically, the remaining lifespan of the filter element will be displayed so that users can understand its remaining lifespan.
[0073] For example, the remaining lifespan of the water purifier's filter cartridge can be displayed to the user through one or more devices such as a display screen, a buzzer, or a speaker; or the remaining lifespan of the filter cartridge can be displayed by sending information to the user's smart device connected to the water purifier. For instance, an LCD screen can be used to display the remaining lifespan of the filter cartridge in real time for the user to view.
[0074] Step 209: When the remaining lifespan of the filter element is lower than the preset remaining lifespan threshold, an alarm is issued.
[0075] The preset remaining lifespan threshold is the preset remaining lifespan threshold when it is recommended to stop using the filter cartridge. For example, the preset remaining lifespan threshold can be 1 minute.
[0076] Specifically, when the remaining lifespan of the filter cartridge falls below a preset threshold, an alarm will be issued to the user, reminding them to stop using the current filter cartridge. The user can then stop using the current filter cartridge by replacing it or by replacing the entire water purifier.
[0077] For example, an alarm can be issued to the user via one or more devices such as a display screen, a buzzer, or a speaker, or by sending a message to the user's smart device connected to the water purifier. For instance, when the remaining lifespan of the filter cartridge is lower than a preset remaining lifespan threshold, a buzzer sounds and a message is pushed to the user's mobile phone that the current remaining lifespan of the filter cartridge is lower than the preset remaining lifespan threshold.
[0078] It should be understood that, although Figure 5 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 5 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

In other words, the solution proposed in this application can determine the remaining lifespan of the filter element of the water purification equipment by obtaining the actual lifespan values corresponding to the impurity content, flow rate, and booster pump current value of the effluent, combined with the corresponding preset weights. It comprehensively considers multiple factors affecting the lifespan of the filter element and uses the actual lifespan values as calculation data, thus improving the accuracy of filter element lifespan calculation and allowing the filter element to be used more effectively.
