[0040] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0041] In order to facilitate understanding of the embodiments of the present application, relevant content regarding filter element life detection is first introduced here.

[0042] As people's living standards are getting higher and higher, the requirements for drinking water are also getting higher and higher. Water purifiers have become one of the basic appliances in people's homes. The filter element is the core component for purifying water quality, and it needs to be replaced on time to ensure excellent filtering effects and the quality of users' drinking water. The life of the filter element is generally detected by a flow meter to detect the flow rate or flow rate of the filter element. When the flow meter is blocked or damaged, the flow rate or flow rate of the filter element detected by the flow meter cannot be obtained, so that the judgment result of the filter element life will be advanced or postponed or even not reported, causing losses to users or affecting users' use of high-quality water quality.

[0043] In order to solve the above-mentioned technical problem that when the flow meter fails, the flow rate or flow velocity detected by the flow meter cannot be obtained, so that the judgment result of the filter element life will be advanced or postponed or even not reported, the present invention proposes a filter element life detection method. The implementation details of the filter element life detection method of this embodiment are specifically described below. The following content is only the implementation details provided for the convenience of understanding, and is not necessary for the implementation of this solution.

[0044] Embodiment 1:

[0045] The filter element life detection method of this embodiment can be applied to electronic devices with communication, computing and data storage capabilities. The specific process can be as follows: Figure 1 As shown, including:

[0046] Step S1, counting the total water flow rate and water flow rate of the filter element currently used in the water purifier.

[0047] The use period of the filter element is divided into a normal period and an abnormal period according to whether the flow meter in the water purifier is normal.

[0048] In one example, detecting whether a flow meter in the water purifier is normal includes:

[0049] Obtaining the number of pulses detected by the flow meter per unit time;

[0050] When the number of pulses detected by the flow meter per unit time does not meet the preset pulse number requirement, it is determined that the flow meter is abnormal, and the time when the flow meter is abnormal is recorded;

[0051] When the number of abnormalities of the flow meter reaches a preset number threshold within a preset first time period, the flow meter is determined to be faulty.

[0052] The pulse number requirement, for example, is that the pulse number detected by the flow meter per unit time is less than a preset lower limit value, or the pulse number detected by the flow meter per unit time is greater than a preset upper limit value.

[0053] Specifically, when in the normal period, the water flow rate and water flow velocity detected by the flow meter correspond to the water flow rate and water flow velocity that need to be counted; when in the abnormal period, the water flow rate and water flow velocity equivalently detected based on the operating status of the pump in the water purifier correspond to the water flow rate and water flow velocity that need to be counted.

[0054] Wherein, when in the abnormal period, the pump is provided with a mapping relationship in the operation state when detecting the water flow volume and the water flow velocity with the flow meter in the previous normal period. That is, when the pump is running, the detection time required for the flow meter to detect the unit water flow volume in the normal time period before the abnormal period, and the detection time may also represent the pump operation time corresponding to the unit water flow volume in the normal time period before the abnormal period.

[0055] In some embodiments, during the abnormal period, equivalently detecting the amount of water flowing and the water flow rate based on the operating state of the pump in the water purifier includes:

[0056] Determine the detection time required by the flow meter to detect the unit water flow in a normal period before the abnormal period, and map the detection time required for the unit water flow to the unit operating time of the pump in the abnormal period, and obtain the water flow and water flow rate based on equivalent detection of the unit operating time;

[0057] A first water flow rate detected by the flow meter in a normal period before the abnormal period is determined, and the first water flow rate is used as the water flow rate equivalently detected by the pump in the abnormal period.

[0058] Step S2, determining whether the service life of the filter element has expired based on the total water flow rate and water flow rate of the filter element.

[0059] For example, when the total water flow rate of the filter element is greater than or equal to a preset water flow rate upper limit, the life of the filter element is determined to have expired; when the water flow rate of the filter element is less than or equal to a preset water flow rate threshold, the life of the filter element is determined to have expired. The water flow rate upper limit and the water flow rate threshold can be set to specific values ​​based on actual experimental tests.

[0060] In order to let the user know the expiration of the life of the filter element in time and replace the filter element to ensure the user's water experience, when the life of the filter element is determined to have expired, a prompt message can also be sent to the user. The prompt message can be any prompt method that can convey information to the user, such as voice prompt, information prompt, light prompt, etc.

[0061] In addition, considering that there may be a problem with the installation of the filter element, resulting in the water flow rate of the filter element being less than or equal to the preset water flow rate threshold when the filter element is just used, thus leading to a misjudgment of the life of the filter element, a judgment condition is added to the step of "when the water flow rate of the filter element is less than or equal to the preset water flow rate threshold, the life of the filter element is judged to have expired", namely:

[0062] Determining whether the total water flow through the filter element is greater than or equal to a preset water flow lower limit;

[0063] When the total water flow rate of the filter element is greater than or equal to a preset water flow rate lower limit, and the water flow rate of the filter element is less than or equal to a preset water flow rate threshold, it is determined that the life of the filter element has expired.

[0064] Specifically, on the basis that the total water flow rate of the filter element is greater than or equal to the preset lower limit of the water flow rate, whether the life of the filter element has expired is further judged by whether the water flow rate of the filter element is less than or equal to the preset water flow rate threshold value. This can avoid the situation where the water flow rate of the filter element is less than or equal to the preset water flow rate threshold value when the filter element is just in use due to problems with the installation of the filter element, thereby leading to misjudgment of the life of the filter element.

[0065] In some embodiments, in order to improve the accuracy of the filter life detection, the water flow upper limit is designed to be set specifically according to the water quality of the user's home. Several levels of water flow upper limit can be set for the filter according to different water qualities. When the filter is used, the water flow upper limit of the filter is set according to the water quality of the inlet water in the filter environment.

[0066] Specifically, the method further includes: detecting the water quality of the inlet water of the water purifier; and adjusting the upper limit of the water flow rate according to the corresponding relationship between the preset water quality and the upper limit of the water flow rate according to the inlet water quality of the water purifier.

[0067] The water quality of the water purifier where the filter element is located can be tested by a TDS (total dissolved solids) pen. The upper limit of the water flow rate of the filter element can be adjusted manually after the user tests the water quality, or it can be automatically adjusted according to the water quality test results of the TDS pen. In this way, the upper limit of the water flow rate of the filter element can be reasonably set in combination with the actual water quality conditions in the user's home, thereby improving the accuracy of the life detection of the filter element and maximizing the utilization rate of the filter element.

[0068] In some embodiments, in order to provide accuracy of the filter element life detection, the method further includes: obtaining the material of the filter element and the flux of the filter element; and determining the water flow rate threshold value according to the material of the filter element and the flux of the filter element.

[0069] Specifically, considering that the materials and fluxes of filter elements of different models are different, and the materials and fluxes of filter elements of different models are different when the filter element expires, that is, when the filtering effect is no longer ideal, the water flow rate of the filter element is also different. Therefore, by setting the corresponding water flow rate threshold according to the material and flux of the filter element, the accuracy of the filter element life detection can be improved.

[0070] The method provided in this embodiment counts the total water flow rate and water flow rate of the filter element currently used in the water purifier; and determines whether the life of the filter element has expired based on the total water flow rate and water flow rate of the filter element; wherein the use period of the filter element is divided into a normal period and an abnormal period according to whether the flow meter in the water purifier is normal; when in the normal period, the water flow rate and water flow rate detected by the flow meter are used as the water flow rate and water flow rate that need to be counted; when in the abnormal period, the water flow rate and water flow rate equivalently detected based on the operating state of the pump in the water purifier are used as the water flow rate and water flow rate that need to be counted, wherein, when in the abnormal period, the pump is set with a mapping relationship in the operating state when detecting the water flow rate and water flow rate with the flow meter in the previous normal period; thereby achieving the accuracy of the life calculation of the filter element to be continuously ensured to the greatest extent when the flow meter of the water purifier fails.

[0071] Embodiment 2:

[0072] Another embodiment of the present application relates to a filter element life detection device. The implementation details of the filter element life detection device of this embodiment are specifically described below. The following content is only for the convenience of understanding the implementation details, and is not necessary for the implementation of this solution. The schematic diagram of the filter element life detection device of this embodiment can be as follows Figure 2 As shown, it includes a statistical module, a life detection module, a fault detection module, a prompt module, a first adjustment module and a second adjustment module.

[0073] The statistics module is used to count the total water flow and water flow rate of the filter element currently used in the water purifier.

[0074] The use period of the filter element is divided into a normal period and an abnormal period according to whether the flow meter in the water purifier is normal; in the normal period, the water flow rate and water flow velocity detected by the flow meter are used as the water flow rate and water flow velocity to be counted; in the abnormal period, the water flow rate and water flow velocity equivalently detected based on the operating state of the pump in the water purifier are used as the water flow rate and water flow velocity to be counted.

[0075] Wherein, when in the abnormal period, the pump is provided with a mapping relationship in the operation state when detecting the water flow volume and the water flow velocity with the flow meter in the previous normal period. That is, when the pump is running, the detection time required for the flow meter to detect the unit water flow volume in the normal time period before the abnormal period, and the detection time may also represent the pump operation time corresponding to the unit water flow volume in the normal time period before the abnormal period.

[0076] In some embodiments, during the abnormal period, equivalently detecting the amount of water flowing and the water flow rate based on the operating state of the pump in the water purifier includes:

[0077] Determine the detection time required by the flow meter to detect the unit water flow in a normal period before the abnormal period, and map the detection time required for the unit water flow to the unit operating time of the pump in the abnormal period, and obtain the water flow and water flow rate based on equivalent detection of the unit operating time;

[0078] A first water flow rate detected by the flow meter in a normal period before the abnormal period is determined, and the first water flow rate is used as the water flow rate equivalently detected by the pump in the abnormal period.

[0079] The fault detection module is used to detect whether the flow meter in the water purifier is normal.

[0080] In one example, the fault detection module is used to obtain the number of pulses detected by the flow meter per unit time; when the number of pulses detected by the flow meter per unit time does not meet the preset pulse number requirement, the flow meter is determined to be abnormal and the time when the flow meter abnormality occurs is recorded; when the number of abnormalities of the flow meter reaches a preset number threshold within a preset first time period, the flow meter is determined to be faulty.

[0081] The pulse number requirement, for example, is that the pulse number detected by the flow meter per unit time is less than a preset lower limit value, or the pulse number detected by the flow meter per unit time is greater than a preset upper limit value.

[0082] The life detection module is used to determine whether the life of the filter element has expired based on the total water flow rate and water flow rate of the filter element.

[0083] In some examples, the life detection module is used to determine that the life of the filter element has expired when the total water flow of the filter element is greater than or equal to a preset water flow upper limit value; and is also used to determine that the life of the filter element has expired when the water flow rate of the filter element is less than or equal to a preset water flow rate threshold value. The water flow upper limit value and the water flow rate threshold value can be set to specific values ​​based on actual experimental detection.

[0084] In order to let the user know the expiration of the life of the filter element in time and replace the filter element to ensure the user's water experience, when the life of the filter element is determined to be expired, the device also includes a prompt module, which is used to send a prompt message to the user when the life of the filter element is determined to be expired. The prompt message can be any prompt method that can convey information to the user, such as voice prompt, information prompt, light prompt, etc.

[0085] In addition, considering that there may be a problem with the installation of the filter element, resulting in the water flow rate of the filter element being less than or equal to the preset water flow rate threshold when the filter element is just in use, thereby causing a misjudgment of the life of the filter element. In the step of "when the water flow rate of the filter element is less than or equal to the preset water flow rate threshold, the life of the filter element is determined to have expired", a judgment condition is added, and the life detection module is also used to judge whether the total water flow of the filter element is greater than or equal to the preset water flow lower limit; when the total water flow of the filter element is greater than or equal to the preset water flow lower limit, and the water flow rate of the filter element is less than or equal to the preset water flow rate threshold, the life of the filter element is determined to have expired.

[0086] Specifically, on the basis that the total water flow rate of the filter element is greater than or equal to the preset lower limit of the water flow rate, whether the life of the filter element has expired is further judged by whether the water flow rate of the filter element is less than or equal to the preset water flow rate threshold value. This can avoid the situation where the water flow rate of the filter element is less than or equal to the preset water flow rate threshold value when the filter element is just in use due to problems with the installation of the filter element, thereby leading to misjudgment of the life of the filter element.

[0087] In some embodiments, in order to improve the accuracy of the filter life detection, the water flow upper limit is designed to be set specifically according to the water quality of the user's home. Several levels of water flow upper limit can be set for the filter according to different water qualities. When the filter is used, the water flow upper limit of the filter is set according to the water quality of the inlet water in the filter environment.

[0088] Specifically, the device also includes a first adjustment module for detecting the inlet water quality of the water purifier, and adjusting the upper limit of water flow according to the corresponding relationship between the preset water quality and the upper limit of water flow according to the inlet water quality of the water purifier.

[0089] The water quality of the water purifier where the filter element is located can be tested by a TDS pen. The upper limit of the water flow rate of the filter element can be adjusted manually after the user tests the water quality, or the upper limit of the water flow rate of the filter element can be automatically adjusted according to the water quality test result of the TDS pen. In this way, the upper limit of the water flow rate of the filter element can be reasonably set in combination with the actual water quality of the user's home, thereby improving the accuracy of the life detection of the filter element and maximizing the utilization rate of the filter element.

[0090] In some embodiments, in order to provide accuracy of the filter element life detection, the device also includes a second adjustment module for obtaining the material of the filter element and the flux of the filter element; and determining the water flow rate threshold according to the material of the filter element and the flux of the filter element.

[0091] Specifically, considering that the materials and fluxes of filter elements of different models are different, and the materials and fluxes of filter elements of different models are different when the filter element expires, that is, when the filtering effect is no longer ideal, the water flow rate of the filter element is also different. Therefore, by setting the corresponding water flow rate threshold according to the material and flux of the filter element, the accuracy of the filter element life detection can be improved.

[0092] The device provided in this embodiment counts the total water flow and water flow rate of the filter element currently used in the water purifier through a statistical module; and determines whether the life of the filter element has expired according to the total water flow and water flow rate of the filter element through a life detection module; wherein the use period of the filter element is divided into a normal period and an abnormal period according to whether the flow meter in the water purifier is normal; when in the normal period, the water flow and water flow rate detected by the flow meter correspond to the water flow and water flow rate that need to be counted; when in the abnormal period, the water flow and water flow rate equivalently detected based on the operating state of the pump in the water purifier correspond to the water flow and water flow rate that need to be counted, wherein, when in the abnormal period, the pump and the flow meter in the previous normal period are set with a mapping relationship in the operating state when detecting the water flow and water flow rate; thereby achieving the maximum accuracy of the life calculation of the filter element when the flow meter of the water purifier fails.

[0093] It is worth mentioning that all modules involved in this embodiment are logic modules. In practical applications, a logic unit can be a physical unit, a part of a physical unit, or a combination of multiple physical units. In addition, in order to highlight the innovative part of this application, this embodiment does not introduce units that are not closely related to solving the technical problems proposed by this application, but this does not mean that there are no other units in this embodiment.

[0094] Embodiment three:

[0095] Based on the above embodiments, this embodiment provides an application example.

[0096] like Figure 3 As shown, the flow meter is detected to be normal. During the period when the flow meter is normal, the water flow rate and water flow velocity detected by the flow meter correspond to the water flow rate and water flow velocity of the filter element that need to be counted; during the period when the flow meter fails, the water flow rate and water flow velocity equivalently detected based on the operating status of the pump in the water purifier correspond to the water flow rate and water flow velocity of the filter element that need to be counted.

[0097] Among them, during the normal period of the flow meter, the water flow rate L1 detected by the flow meter is based on the relationship between the number of pulses corresponding to the flow meter and the water flow rate, and the water flow rate L per second is calculated according to the number of pulses actually detected by the flow meter per second. 秒 And the water flow rate QB, the unit of QB is liters per second. For example, the water flow rate L per second 秒 If the flow rate is 1 liter of water per second, the water flow rate is accumulated in units of 1 liter of water, that is, the detected water flow rate L1 is increased by 1 for every liter of water flow.

[0098] During the period of flow meter abnormality, the water flow rate QB detected by the flow meter in the previous normal period before the abnormal period is used as the water flow rate detected in the abnormal period. When in the abnormal period, the pump and the flow meter in the previous normal period are set with a mapping relationship QP in the running state when detecting the water flow rate and the water flow rate. QP represents the running time t of the pump corresponding to each liter of water flowing through, QP = 1 / QB. During the abnormal period, the detected water flow L2 is increased by 1 for every t seconds of the running time of the pump.

[0099] Specifically, the water flow rate detected by the flow meter in a normal period before the current abnormal period is an average value detected by the flow meter in the normal period before the current abnormal period.

[0100] The total water flow rate and water flow rate of the filter element currently used in the water purifier are counted. The total water flow rate of the filter element currently used includes the sum of the water flow rate L1 detected by the flow meter during the normal period and the water flow rate L2 detected by the flow meter during the abnormal period during the use of the filter element.

[0101] The total amount of water flowing through the filter element and the water flow rate are used to determine whether the filter element has expired. Figure 3 As shown, first determine the total water flow L of the filter element 已过 Is it greater than or equal to the preset lower limit of water flow L? min , when the total water flow of the filter element L 已过 Less than the lower limit of water flow L minWhen the total water flow rate L of the filter element is 已过 Greater than or equal to the preset lower limit of water flow L min When the total water flow rate L of the filter element is further determined 已过 Is it greater than or equal to the preset upper limit of water flow L? max , when the total water flow of the filter element L 已过 Greater than or equal to the upper limit of the amount of water L max When the total water flow rate L of the filter element is 已过 Less than the preset upper limit of water flow L max When the water flow rate QB of the filter element is less than or equal to the preset water flow rate threshold QB 到期 When the water flow rate QB of the filter element is less than or equal to the preset water flow rate threshold QB 到期 When the filter element is judged to have a service life that is not expired, the filter element service life judgment process ends; when the water flow rate QB of the filter element is less than or equal to the preset water flow rate threshold QB 到期 When the filter element is used, it is determined that the life of the filter element has expired, and the process for determining the life of the filter element is terminated.
