[0002] Currently, water purifiers are mainly used to reduce the total dissolved solids (TDS) level of drinking water to meet safe drinking standards. However, a high TDS level will cause the water purifier filter cartridge to wear out too quickly, requiring timely cleaning.

[0003] In existing technologies, the flushing function of a water purifier can be manually triggered to clean the filter cartridge; alternatively, a flushing command can be pre-set to be issued when the water purifier reaches a fixed water production time or volume to clean the filter cartridge. However, due to differences in water quality in different regions, the consumption rate of the filter cartridge also varies, and a fixed cleaning method cannot guarantee effective cleaning, thus reducing the lifespan of the filter cartridge. Summary of the Invention

[0004] This invention provides a method, apparatus, electronic device, and storage medium for rinsing water purifier filter cartridges, which can more effectively rinse the filter cartridges and increase their service life.

[0005] In a first aspect, the present invention provides a method for rinsing a water purifier filter element, comprising:

[0016] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the rinsing method for a water purifier filter element as described in any embodiment of the present invention.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] Figure 1This is a schematic flowchart of a rinsing method for a water purifier filter element provided by the present invention. This method can be executed by a rinsing device for the water purifier filter element provided by the present invention, which can be implemented using software and / or hardware. In a specific embodiment, the device can be integrated into an electronic device, such as a water purifier. The following embodiments will illustrate this using the integration of the device into an electronic device as an example. Figure 1 The method may specifically include the following steps:

[0026] Step 101: Determine the average total dissolved solids (TDS) value of the water entering the water purifier based on the location information of the water purifier.

[0027] Total dissolved solids refers to the total amount of solids dissolved in water, expressed in milligrams per liter.

[0028] Specifically, the location information of the water purifier can be obtained through a positioning system pre-installed inside the purifier, through the purifier's internet connection, or by the user uploading the purifier's location information after binding the purifier to their device. For example, the water purifier's location information might be that it is located in a specific administrative district of a city.

[0029] After obtaining the location information of the water purifier, the average TDS value of that geographical location is queried and used as the average TDS value of the water entering the water purifier.

[0030] In this embodiment of the invention, the average TDS value of the water entering the water purifier is determined based on the location information of the water purifier, providing a data basis for subsequently determining the first TDS difference.

[0031] Step 102: Obtain the initial TDS value of the water purifier's output water, and determine the first TDS difference based on the inlet TDS value and the initial output TDS value.

[0032] Optionally, the initial TDS value of the water purifier is determined based on the historical TDS values ​​of the water purifier after the filter cartridge was replaced within a historical period.

[0033] Specifically, each time the filter cartridge is replaced, the TDS value of the output water is detected by a probe installed inside the water purifier. The average TDS value of the output water within 24 hours after each filter cartridge replacement is recorded, resulting in multiple historical output water TDS values. Then, the initial TDS value is determined based on the average of the historical output water TDS values ​​after multiple filter cartridge replacements over a period of time. Next, the initial TDS value is subtracted from the inlet water TDS value to obtain the first TDS difference value.

[0034] In this embodiment of the invention, by determining the initial effluent TDS value, a first TDS difference is obtained, which provides a data basis for judging the subsequent filter cartridge flushing.

[0035] Step 103: Determine the current TDS value of the water purifier's outlet water, and determine the second TDS difference based on the inlet water TDS value and the current outlet water TDS value.

[0036] For example, the current TDS value of the effluent is obtained by using any effluent more than 24 hours after the filter cartridge is replaced; then the current TDS value of the effluent is subtracted from the TDS value of the influent to obtain the second TDS difference.

[0037] In this embodiment of the invention, by determining the current TDS value of the effluent, a second TDS difference is obtained, which provides a data basis for judging the subsequent filter cartridge flushing.

[0038] Step 104: Determine the ratio of the second TDS difference to the first TDS difference, and when the ratio meets the preset conditions, flush the filter element of the water purifier.

[0039] Optionally, the preset condition refers to the ratio of the second TDS difference to the first TDS difference being less than a preset ratio.

[0040] Optionally, a preset ratio is determined based on the ratio of the second TDS difference to the first TDS difference when the water quality treated by the water purifier does not meet the preset requirements within a historical time period. Therefore, when the ratio of the second TDS difference to the first TDS difference is less than the preset ratio, it can be determined that the filter element has been somewhat consumed, and its achievable water purification effect no longer meets the water purifier's purification requirements, necessitating filter element flushing.

[0041] In this embodiment of the invention, the ratio of the second TDS difference to the first TDS difference is first determined, and then a preset ratio is obtained. The comparison between the two determines whether to flush the filter element, so that the water purifier can flush the filter element more effectively and increase the service life of the filter element.

[0042] The present invention determines the average total dissolved solids (TDS) value of the influent water of the water purifier based on the location information of the water purifier; obtains the initial effluent TDS value of the water purifier, and determines a first TDS difference based on the influent TDS value and the initial effluent TDS value; determines the current effluent TDS value of the water purifier, and determines a second TDS difference based on the influent TDS value and the current effluent TDS value; determines the ratio of the second TDS difference to the first TDS difference, and flushes the filter element of the water purifier when the ratio meets a preset condition. This invention determines the average TDS value of the incoming water based on the location information of the water purifier, eliminating the need to test the TDS value of the incoming water. Then, it determines a first TDS difference based on the incoming water TDS value and the initial outgoing water TDS value, and a second TDS difference based on the incoming water TDS value and the current outgoing water TDS value. The ratio of the second TDS difference to the first TDS difference is calculated, and this ratio is used to determine the current level of wear on the water purifier filter. Flushing is only performed when the filter has reached sufficient wear, achieving more effective rinsing of the filter and increasing its lifespan.

[0043] Figure 2 This is another schematic diagram of the flushing method for the water purifier filter element provided by the present invention, as shown below. Figure 2 As shown, the method may include the following steps:

[0044] Step 201: Based on the location information of the water purifier, search the table of relationship between location information and inlet water TDS value to determine the inlet water TDS value of the water purifier.

[0045] Specifically, the location information of the water purifier is obtained by positioning, and the inlet TDS value of the water purifier is determined by searching in the relationship table between location information and inlet TDS value.

[0046] In this embodiment of the invention, the inlet TDS value of the water purifier is determined by searching the relationship table between the location information and the inlet TDS value based on the location information of the water purifier, thus providing a data basis for subsequently determining the first TDS difference.

[0047] Step 202: Determine the initial effluent TDS value based on the historical effluent TDS values ​​after the filter cartridge was replaced within the historical time period.

[0048] For example, after replacing the filter cartridge in a water purifier, record the number of times the water is dispensed and the TDS value of each dispensed water within 24 hours after the filter cartridge replacement. Calculate and record the average TDS value of the dispensed water within 24 hours as the historical TDS value. After multiple filter cartridge replacements, obtain multiple historical TDS values, calculate the average of the multiple historical TDS values, and use it as the initial TDS value for the dispensed water.

[0049] In this embodiment of the invention, the initial TDS value of the effluent is determined based on the historical TDS values ​​of the effluent after the filter cartridge of the water purifier is replaced within a historical time period, providing a data basis for subsequently determining the first TDS difference.

[0050] Step 203: Subtract the initial effluent TDS value from the influent TDS value to obtain the first TDS difference.

[0051] Specifically, after determining the influent TDS value and the initial effluent TDS value, the first TDS difference can be determined according to Formula 1.

[0052] △T1=T1-T2 Formula 1

[0053] Where △T1 represents the first TDS difference, T1 represents the influent TDS value, and T2 represents the initial effluent TDS value.

[0054] In this embodiment of the invention, the first TDS difference is calculated, providing a data basis for determining the subsequent filter element rinsing.

[0055] Step 204: Determine the current TDS value of the water purifier's outlet water. Subtract the current TDS value of the outlet water from the inlet water TDS value to obtain the second TDS difference.

[0056] Specifically, after determining the influent TDS value and the current effluent TDS value, the second TDS difference can be determined according to Formula 2.

[0057] △T2=T1-T3 Formula 2

[0058] Where △T2 represents the second TDS difference and T3 represents the current effluent TDS value.

[0059] In this embodiment of the invention, the second TDS difference is calculated, providing a data basis for determining the subsequent filter element flushing.

[0060] Step 205: Determine the preset ratio based on the ratio of the second TDS difference to the first TDS difference when the water quality treated by the water purifier does not meet the preset requirements during the historical time period.

[0061] Among them, the preset requirements refer to the water purification effect that the water purifier can achieve when it is working normally, such as the TDS value of the water output of the water purifier should not be greater than 100 mg / L.

[0062] Specifically, when the water quality treated by the water purifier within a historical period does not meet the preset requirements, meaning the water purifier filter cannot achieve the preset purification effect, the filter needs to be flushed. In this case, after determining the second TDS difference and the first TDS difference, the preset ratio can be determined according to Formula 3.

[0063] a=△T2 ’ / △T1 Formula 3

[0064] where a is a preset ratio, and △T2 ’ is the second TDS difference when the water quality treated by the water purifier during the historical time period does not meet the preset requirements.

[0065] In the embodiments of the present invention, calculations are performed based on the water quality treated by the water purifier during the historical time period not meeting the preset requirements to obtain the preset ratio when the water purifier filter element needs to be flushed, which plays a decisive role in the subsequent judgment of filter element flushing.

[0066] Step 206: Determine the ratio of the second TDS difference to the first TDS difference, and when it is determined that the ratio is less than the preset ratio, flush the filter element of the water purifier.

[0067] Specifically, after determining the second TDS difference and the first TDS difference, the ratio can be determined according to Formula 4.

[0068] A = △T2 / △T1 Formula 4

[0069] where A represents the ratio of the second TDS difference to the first TDS difference.

[0070] When it is determined that A < a, it is determined that the filter element of the water purifier cannot achieve the preset water purification effect, and the filter element of the water purifier is flushed.

[0071] In the embodiments of the present invention, by determining the ratio of the second TDS difference to the first TDS difference and comparing it with the preset ratio, it plays a decisive role in judging whether to flush the filter element of the water purifier, enabling the water purifier to perform more effective flushing of the filter element and increasing the service life of the filter element.

[0072] The solution of the present invention determines the average total dissolved solids TDS value of the water inlet of the water purifier according to the position information of the water purifier; obtains the initial outlet TDS value of the water purifier, and determines the first TDS difference according to the inlet TDS value and the initial outlet TDS value; determines the current outlet TDS value of the water purifier, and determines the second TDS difference according to the inlet TDS value and the current outlet TDS; determines the ratio of the second TDS difference to the first TDS difference, and when it is determined that the ratio meets the preset conditions, flushes the filter element of the water purifier. That is, the present invention determines the average inlet TDS value according to the position information of the water purifier without detecting the inlet TDS value of the water purifier; then determines the first TDS difference according to the inlet TDS value and the initial outlet TDS value, determines the second TDS difference according to the inlet TDS value and the current outlet TDS, calculates the ratio of the second TDS difference to the first TDS difference, judges the current consumption degree of the water purifier filter element through the ratio, and flushes when the water purifier filter element has reached sufficient consumption, realizing more effective flushing of the water purifier filter element and increasing the service life of the filter element.
