Description

Technical Field

[0001] This invention relates to filter cartridge monitoring technology, and more particularly to a filter cartridge monitoring method. Background Technology

[0002] Nowadays, people are paying more and more attention to the health of their drinking water. As a result, water purifiers have become a focus of public attention.

[0003] However, because ordinary consumers cannot distinguish between genuine and counterfeit water purifier filter cartridges, some counterfeit cartridges exist on the market. While these counterfeit cartridges are inexpensive, their quality is far inferior to genuine ones. This results in consumers purchasing counterfeit cartridges being unable to obtain properly purified water, threatening their health. However, the sale of counterfeit cartridges is usually quite covert, making it difficult for brands to combat them. Therefore, obtaining clues about counterfeit cartridges has become a crucial step in combating this problem. Summary of the Invention

[0004] This invention provides a filter cartridge monitoring method to obtain clues about counterfeit filter cartridges, in order to support further efforts to combat counterfeit filter cartridges.

[0005] In a first aspect, embodiments of the present invention provide a filter cartridge monitoring method, comprising:

[0006] Obtain the number of filter cartridges used in each group per unit time;

[0007] Obtain the number of filter cartridges replaced in each group per unit time;

[0008] The ratio between the number of filter cartridges replaced in each group and the number of filter cartridges used up is taken as the filter cartridge replacement rate for each group.

[0009] The marking group is determined according to the preset rules.

[0010] Optionally, after determining the tag group according to preset rules, the method further includes:

[0011] The system pushes out warning messages that include information about the marked groups.

[0012] Optionally, determining the tag group according to preset rules includes:

[0013] The replacement rate of each group is compared with the benchmark replacement rate. If the replacement rate of the first group is lower than the benchmark replacement rate, then the first group is designated as the marked group.

[0014] Optionally, the average value of the replacement rate of the first group within a preset time period is obtained, and the preset value is subtracted from the average value to obtain the benchmark replacement rate.

[0015] Optionally, obtaining the number of filter replacements for each group per unit time includes:

[0016] The number of filter elements replaced is determined by the number of completed filter element replacement work orders. 6. The filter element monitoring method according to claim 1, characterized in that determining the marker group according to preset rules includes:

[0017] The replacement rate of all groups is ranked, and if the second group's ranking is lower than the benchmark ranking, then the second group is designated as the marked group.

[0018] Optionally, the groups may be defined based on region and / or filter type.

[0019] Optionally, the unit of time may include a day or a month.

[0020] Optionally, obtain the number of used filter cartridges per group per unit time, including:

[0021] Obtain the filter cartridge expiration determination result of the water purifier in the third group. If the water purifier determines that the filter cartridge of the water purifier has expired, then the water purifier is determined to be a water purifier with used filter cartridges.

[0022] Alternatively, the filter cartridge usage time of the water purifier in the third group can be obtained. If the filter cartridge usage time exceeds the filter cartridge lifespan, then the water purifier is determined to be the water purifier with the filter cartridge exhausted.

[0023] The number of water purifiers that have used up their filter cartridges is defined as the number of filter cartridges used up.

[0024] Optionally, the groups are defined according to the region, and the color of the map corresponding to each group is filled according to the core replacement rate of each group, and the color of the marked group is filled with a first color.

[0025] Secondly, embodiments of the present invention also provide a filter cartridge monitoring method, comprising:

[0026] Get the number of after-sales core replacement orders completed for each group within a unit of time;

[0027] Get the number of after-sales core replacement orders generated for each group within a unit of time;

[0028] The ratio between the number of completed after-sales core replacement orders and the number of generated after-sales core replacement orders in each group is taken as the completion rate of each group;

[0029] The completion rates of all the groups are ranked. If the fourth group's ranking is lower than the benchmark ranking, then the fourth group is designated as the flag group.

[0030] This invention embodiment obtains the number of used filter cartridges in each group within a unit time; obtains the number of filter cartridges replaced in each group within a unit time; uses the ratio between the number of filter cartridges replaced and the number of used filter cartridges in each group as the replacement rate for each group; and determines marked groups according to preset rules. Because the data related to the replacement rate of the marked groups is abnormal, these marked groups are highly likely to have used counterfeit filter cartridges, and therefore an investigation should be launched against them. This invention embodiment obtains a starting point for investigating counterfeit filter cartridges by acquiring marked groups, thus supporting further actions to combat counterfeit filter cartridges.

[0035] The present invention 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 invention 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 invention, and not all of the structures.

[0036] Figure 1 A flowchart of a filter cartridge monitoring method provided in an embodiment of the present invention is shown below. Figure 1 This invention provides a filter cartridge monitoring method, which can be implemented using hardware and / or software. The method specifically includes the following steps:

[0037] S11: Obtain the number of filter cartridges used in each group per unit time;

[0038] The number of used filter cartridges can be the number of filter cartridges that a user in a group uses up within a unit of time.

[0039] Optionally, groups can be formed based on region and / or filter type. Groups can be based on region, for example, by province, with each province forming a group. Alternatively, groups can be formed by city, district, or the service coverage area of ​​an after-sales service station. Groups can also be formed by filter type; water purifiers have many types of filters, such as PP cotton filters, pre-activated carbon filters, ultrafiltration membrane filters, reverse osmosis membrane filters, and post-activated carbon filters. Groups can be formed based on these types. Groups can also be formed based on both region and filter type. For example, a certain type of filter from a specific city can be grouped together. The grouping method can be determined based on actual needs.

[0040] The unit of time can be a period of time determined according to actual needs, and the embodiments of the present invention do not limit the duration of the unit of time. Optionally, the unit of time may include a day or a month.

[0041] S12: Obtain the number of filter cartridges replaced in each group per unit time;

[0042] The filter replacement quantity can be the number of filter replacements made by users within a group through official channels within a unit of time.

[0043] S13: The ratio between the number of filter cartridges replaced in each group and the number of filter cartridges used up is taken as the replacement rate of each group;

[0044] S14: Determine the tag group according to the preset rules.

[0045] The preset rules can be used to determine the marked groups based on the filter replacement rate or ranking of each group, or based on factors related to the filter replacement rate, such as the upward or downward trend of the filter replacement rate. A marked group may be one that is marked because of a low filter replacement rate or ranking. Since the marked group has a low replacement rate or ranking, it is highly likely that users within the marked group are using counterfeit filters, or filters obtained from unofficial channels, resulting in filter replacements not being counted in the filter replacement count, thus leading to a low replacement rate or ranking. Therefore, investigating the marked groups is sufficient to combat counterfeit filters. This invention provides a direction for combating counterfeit filters.

[0046] Figure 2 A flowchart of a filter cartridge monitoring and early warning method provided in an embodiment of the present invention is shown below. Figure 2 In other embodiments, after determining the tag group according to preset rules, the method further includes:

[0047] S15: Push alert information including information about the tag group.

[0048] This invention can send push notifications to administrators to alert them if a marked group exhibits abnormalities, potentially indicating counterfeit filter cartridges. This prompts administrators to pay attention to the marked group. Furthermore, by providing notifications of abnormalities to marked groups without requiring administrator intervention, this invention significantly simplifies the fight against counterfeit filter cartridges.

[0049] In other embodiments, determining the tag group according to preset rules includes:

[0050] The replacement rate of each group is compared with the benchmark replacement rate. If the replacement rate of the first group is lower than the benchmark replacement rate, the first group is designated as the marked group.

[0051] The baseline filter replacement rate can be determined based on actual needs and past experience. This article will provide a method for determining the baseline filter replacement rate below. A replacement rate lower than the baseline rate may indicate counterfeit filter elements. Therefore, the replacement rate of each group can be assessed. If the replacement rate of any group is lower than the baseline rate, that group is designated as a flagged group. This method allows for quick and accurate identification of flagged groups, facilitating further efforts to combat counterfeit filter elements.

[0052] In other embodiments, the average value of the replacement rate of the first group within a preset time period is obtained, and the average value is subtracted from the preset value to obtain the baseline replacement rate.

[0053] The preset time can be determined according to actual needs, and can be a historical period up to the current time. The average replacement rate of the first group within the preset time can be calculated. This average reflects the consistent replacement rate of this group. If, within this unit of time, the replacement rate of this group shows a decrease greater than the preset value (i.e., below the baseline replacement rate), it is highly likely that counterfeit filter elements have begun to appear in this group. Therefore, it is necessary to designate this group as a marked group. The preset value can be determined according to actual needs.

[0054] In other embodiments, obtaining the number of filter replacements per group per unit time includes:

[0055] The number of filter elements to be replaced is determined by the number of filter element replacement work orders completed.

[0056] The number of filter replacements can be determined by the number of filter replacement work orders completed as reported by the after-sales department. Alternatively, the number of filter replacement work orders completed by the group within a given time period can be obtained directly from the after-sales department via a data interface, and this number can be used as the filter replacement quantity. This method is convenient and reduces the overhead associated with obtaining the number of filter replacement work orders completed within a given time period.

[0057] In other embodiments, determining the tag group according to preset rules includes:

[0058] Rank the replacement rates of all groups. If the second group's ranking is lower than the benchmark ranking, then the second group is designated as the flag group.

[0059] This system allows ranking the filter replacement rates of each group and setting a baseline ranking as needed. If any group ranks below the baseline, it is designated as a flagged group. For example, the baseline ranking could be set to fourth from the bottom. If a group's filter replacement rate is too low, below the baseline, it may be due to the presence of counterfeit filters within that group. Therefore, designating groups below the baseline as flagged groups can support further efforts to combat counterfeit filters.

[0060] In other embodiments, obtaining the number of used filter cartridges per group per unit time includes:

[0061] Obtain the filter cartridge expiration determination result of the water purifier in the third group. If the water purifier determines that the filter cartridge has expired, then the water purifier is determined to be a water purifier with used up filter cartridges.

[0062] Alternatively, obtain the filter cartridge usage time of the water purifier in the third group. If the filter cartridge usage time exceeds the filter cartridge lifespan, then determine that the water purifier is a filter cartridge depleted.

[0063] The number of water purifiers that have used up all their filter cartridges is taken as the number of filter cartridges used up.

[0064] Water purifiers can be categorized into smart networked water purifiers and non-smart networked water purifiers. For smart networked water purifiers, the system can access the filter cartridge expiration flag. The purifier can upload this flag over the network. If any purifier in the group uploads a flag of "1" (indicating that one of its filter cartridges has expired), that purifier is considered to have exhausted its filter cartridges, and the number of used filter cartridges in the group is incremented. After replacing a filter cartridge, the water purifier needs to reset its filter cartridge expiration flag to reassess whether the cartridge has expired. Optionally, if the user resets the flag and the corresponding filter cartridge expiration flag remains "1," it means the user only reset the flag and did not replace the filter cartridge. Therefore, in this case, the number of used filter cartridges in the group remains unchanged.

[0065] For non-smart, non-networked water purifiers, the last filter replacement time or new machine installation time can be obtained through after-sales service orders. Alternatively, a mobile app can be used to request the user to input the last filter replacement time or new machine installation time. Then, the difference between the filter replacement time in the after-sales service order and the current time is checked against the filter lifespan. The filter lifespan can be determined based on the type of filter. Generally, the lifespan of PP cotton filters is 3-6 months, pre-activated carbon filters are 3-6 months, ultrafiltration membrane filters are 3-6 months, reverse osmosis membrane filters are 6-12 months, and post-activated carbon filters are 6-12 months. If the filter lifespan exceeds the filter lifespan, the water purifier is considered a filter-used water purifier. Therefore, the number of used filters can be determined by calculating the total number of water purifiers with used filters in the group.

[0066] Figure 3 This invention provides a map that fills in color based on the core replacement rate; in other embodiments, the map is divided into groups based on the region, and the color of the map corresponding to each group is filled according to the core replacement rate of each group, with the color of the marked group filled as the first color 1.

[0067] This system allows for grouping based on different regions. After determining the marker group, the map area corresponding to that group can be filled with a first color (1). Areas outside the marker group can be filled with a second color. The first and second colors can be determined according to actual needs. For example, the first color can be set to red, and the second color to green. Alternatively, areas outside the marker group can be filled with colors according to the filter replacement rate, with color gradients corresponding to different replacement rates. By filling the map area containing the marker group with the first color (1), the location characteristics, distribution, and area ratio of the marker group to all groups can be clearly and intuitively displayed. This facilitates analysis by management personnel and provides support for further combating counterfeit filter cartridges.

[0068] Figure 4 A flowchart of another filter cartridge monitoring method provided in an embodiment of the present invention is shown below. Figure 4 This invention also provides a filter cartridge monitoring method, comprising:

[0069] S21: Get the number of after-sales core replacement orders completed for each group within a unit of time;

[0070] The number of completed after-sales core replacement orders refers to the number of core replacement orders completed by after-sales service personnel.

[0071] Optionally, groups can be formed based on region and / or filter type. Groups can be based on region, for example, by province, with each province forming a group. Alternatively, groups can be formed by city, district, or the service coverage area of ​​an after-sales service station. Groups can also be formed by filter type; water purifiers have many types of filters, such as PP cotton filters, pre-activated carbon filters, ultrafiltration membrane filters, reverse osmosis membrane filters, and post-activated carbon filters. Groups can be formed based on these types. Groups can also be formed based on both region and filter type. For example, a certain type of filter from a specific city can be grouped together. The grouping method can be determined based on actual needs.

[0072] The unit of time can be a period of time determined according to actual needs, and the embodiments of the present invention do not limit the duration of the unit of time. Optionally, the unit of time may include a day or a month.

[0073] S22: Get the number of after-sales core replacement orders generated per unit time;

[0074] Among them, the number of after-sales replacement orders refers to the number of replacement orders created by the after-sales department based on customer replacement requests.

[0075] S23: The ratio between the number of completed after-sales core replacement orders and the number of generated after-sales core replacement orders in each group is used as the completion rate of each group;

[0076] S24: Rank the completion rates of all groups. If the fourth group's ranking is lower than the baseline ranking, then the fourth group is designated as the marked group.

[0077] In some cases, after-sales personnel may privately sell counterfeit filter cartridges to customers after a home visit, leading to customers canceling their replacement orders. Therefore, ranking completion rates can help identify this problem. A baseline ranking can be set according to actual needs, and the ranking of each group can be compared with the baseline ranking. If a group's ranking is lower than the baseline ranking, that group is designated as a flagged group. For example, the baseline ranking can be set as tenth place, and groups ranked lower than tenth can be designated as flagged groups. Investigating only the flagged groups is sufficient to investigate counterfeit filter cartridges, providing a direction for combating counterfeit filter cartridges. Optionally, the above groups can be replaced with individual after-sales personnel who provide on-site filter replacements. By ranking the completion rate of each after-sales personnel who provide on-site replacements and identifying those ranked lower than the baseline ranking as flagged individuals, the investigation of counterfeit filter cartridges can be effectively directed.

[0078] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
