Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment control, and in particular to a method, device, equipment, storage medium and program product for identifying the life of a filter element. Background Art

[0002] As people's living standards continue to improve, their requirements for drinking water are also increasing. Water purifiers have become one of the basic appliances in people's homes. The filter element is the core material for purifying water quality and needs to be replaced on time to ensure excellent filtering effects. The life of the filter element is generally determined by a flow meter that detects the flow rate flowing through the filter element or the water production time. The former method will not report the filter element life when the flow meter is damaged. The latter method uses the water production time to determine the parameters. For the sake of safety, a large margin is left when setting the parameters, which may cause waste in places with good water quality. Both of the above judgment methods will lead to inaccurate identification of the filter element life, and when the user's water consumption is small or not used for a long time, the filter element expiration conditions may not be met for a considerable period of time. If there is no prompt for element replacement for too long, it will cause confusion to the user and affect the user experience. Summary of the Invention

[0003] In view of this, the present invention provides a method, device, equipment, storage medium and program product for identifying the life of a filter element to solve the problem of inaccurate identification of the life of a filter element.

[0004] In a first aspect, the present invention provides a method for identifying the life of a filter element, the method comprising:

[0005] During the operation of the filter element, obtain the water flow rate, water production time and power-on time of the filter element;

[0006] Check whether the flow meter has any abnormality;

[0007] If the flow meter does not show any abnormality, the filter element life span is determined based on the water flow rate and the power-on time of the whole machine.

[0008] If the flow meter is abnormal, the filter element life will be determined based on the water production time and the power-on time of the entire machine.

[0009] The method for identifying the life of a filter element provided in an embodiment of the present invention detects whether the flow meter has any abnormality during the operation of the filter element. If no abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water flow rate and the power-on time of the entire machine. If an abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water production time and the power-on time of the entire machine. By integrating the water flow rate, water production time, the power-on time of the entire machine and the status of the flow meter, the present invention can accurately identify the life of the filter element, avoid situations such as waste of the filter element due to unexpired life or excessive use affecting water quality, and thus improve user experience and satisfaction.

[0010] In an optional embodiment, whether the life of the filter element has expired is determined based on the water flow rate and the power-on time of the entire machine, including: obtaining the rated water flow rate and rated power-on time of the filter element; determining whether the water flow rate reaches the rated water flow rate, and if so, determining that the life of the filter element has expired; if not, determining the remaining water production time based on the rated water flow rate, water flow rate and water production time, and determining whether the power-on time of the entire machine reaches the rated power-on time, and if so, determining that the life of the filter element has expired.

[0011] The present invention identifies the filter element life according to the water flow rate and the power-on time of the whole machine when there is no abnormality in the flow meter, thereby accurately monitoring the water purification condition of the filter element and intuitively reflecting the impact of the water purification work on the filter element. At the same time, combined with the power-on time of the whole machine, it avoids the situation where bacteria grows and affects the water quality due to long-term power-on without water purification.

[0012] In an optional embodiment, whether the life of the filter element has expired is determined based on the water production time and the power-on time of the entire machine, including: obtaining the remaining water production time; determining whether the water production time reaches the remaining water production time, and if so, determining that the life of the filter element has expired; if not, determining whether the power-on time of the entire machine reaches the rated power-on time, and if so, determining that the life of the filter element has expired.

[0013] The present invention can avoid the situation where the flow meter is damaged and the filter element life cannot be identified by identifying the filter element life according to the water production time and the power-on time of the entire machine when an abnormality occurs in the flow meter, thereby improving user experience.

[0014] In an optional embodiment, the remaining water production time is determined based on the rated water flow, the water flow rate and the water production time, including: calculating the difference between the rated water flow rate and the water flow rate to obtain the remaining water flow rate; calculating the ratio of the water production time and the water flow rate to obtain the unit water production time; calculating the product of the remaining water flow rate and the unit water production time to obtain the remaining water production time.

[0015] The present invention uses a flow meter to assist in monitoring the unit water production time of the filter element, which can take into account the situation that the operating capacity of the pump will be reduced during long-term operation, thereby updating the remaining water production time and reducing the calculation deviation of the flow meter caused by the reduction in the pump operating capacity.

[0016] In an optional embodiment, obtaining the rated water flow rate of the filter element includes: obtaining the initial water flow rate, the minimum water flow rate and the preset attenuation slope of the filter element; calculating the flow rate difference between the initial water flow rate and the minimum water flow rate, and taking the ratio of the flow rate difference to the attenuation slope as the rated water flow rate.

[0017] The present invention can determine the upper limit of the filtration capacity of the filter element by calculating the rated water flow rate of the filter element, thereby providing a comparison basis for the water flow rate and accurately identifying whether the filter element has expired.

[0018] In an optional embodiment, the detecting whether the flow meter is abnormal includes: obtaining the number of pulses of the flow meter, and if the number of pulses is less than a preset pulse value, determining that the flow meter is abnormal, otherwise determining that the flow meter is not abnormal.

[0019] The present invention detects whether the flow meter has any abnormality according to its working status, which can avoid the situation where the filter element life cannot be identified due to the abnormality of the flow meter, resulting in no prompt for element replacement for a long time, providing users with accurate and reliable element replacement prompts and improving user experience.

[0020] In an optional embodiment, if an abnormality occurs in the flow meter, whether the life of the filter element has expired is determined based on the water production time and the power-on time of the entire machine. The step also includes: if the flow meter returns to normal, returning to the step of detecting whether the flow meter has an abnormality; if the flow meter does not have an abnormality, determining whether the life of the filter element has expired based on the water flow rate and the power-on time of the entire machine.

[0021] The present invention identifies the filter element life by the water flow rate when the flow meter returns to normal, and can select a relatively more intuitive and accurate identification method, thereby avoiding errors caused by the decline in pump operating capacity due to long-term water production, and improving the accuracy of filter element life identification.

[0022] In a second aspect, the present invention provides a device for identifying the life of a filter element, the device comprising:

[0023] The information acquisition module is used to obtain the water flow rate, water production time and power-on time of the filter element during the operation of the filter element;

[0024] Anomaly detection module, used to detect whether the flow meter has any abnormality;

[0025] The first life identification module is used to determine whether the filter element has expired based on the water flow rate and the power-on time of the whole machine if there is no abnormality in the flow meter;

[0026] The second life identification module is used to determine whether the life of the filter element has expired based on the water production time and the power-on time of the entire machine if an abnormality occurs in the flow meter.

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0039] The present invention is applicable to scenarios where filter cartridge life is identified during the water purification process of a water purifier, thereby providing timely filter replacement prompts to the user. Taking a water purifier as an example, the present invention provides a method for identifying filter cartridge life by comprehensively analyzing water flow rate, water production time, machine power-on time, and flowmeter status to accurately identify filter cartridge life.

[0040] According to an embodiment of the present invention, an embodiment of a method for identifying the life of a filter element is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0041] In this embodiment, a method for identifying the life of a filter element is provided, which can be used in the above-mentioned water purifier. Figure 1 FIG. 1 is a flow chart of a method for identifying the life of a filter element according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0042] Step S101 , during the operation of the filter element, obtaining the water flow rate, water production time and power-on time of the filter element.

[0043] Specifically, in an embodiment of the present invention, the water purifier uses a filter element to achieve physical filtration and chemical filtration, thereby removing impurities, odors or harmful substances in the water. As an important component of the water purifier, the filter element will gradually reduce its filtering effect as the water purification time increases, and may also cause blockages, increase the risk of bacterial growth, etc., so it is necessary to remind the user to replace it in time. By deploying a flow meter on the water purifier, the embodiment of the present invention can measure the water flow through the filter element during the operation of the filter element. On the one hand, it is used to control the water output, and on the other hand, it measures the water flow through the filter element. At the same time, after the water purifier is powered on, regardless of whether water purification is carried out, the power-on time of the whole machine will be recorded, and when the filter element filters the water flow to make water, the water making time will be recorded. Therefore, the power-on time of the whole machine must be greater than the water making time.

[0044] Step S102: Check whether the flow meter is abnormal.

[0045] Specifically, in an embodiment of the present invention, the flow meter, as an electronic device, will inevitably cause abnormal conditions due to various reasons, including flow meter damage, blockage, water source switch problems, accessory failure, insufficient water pump boost, pipe bending or deformation, too low water temperature, insufficient output power of the power adapter, etc. In this case, if the water purifier can still prepare purified water normally, the water flow through the filter element is still increasing, but the flow meter cannot measure it, resulting in the inability to accurately identify whether the life of the filter element has expired. Therefore, the embodiment of the present invention obtains the number of pulses of the flow meter according to the working status of the flow meter. If the number of pulses is less than the preset pulse value, it is determined that the flow meter has an abnormality, otherwise it is determined that the flow meter has no abnormality. Then, when an abnormality occurs or no abnormality occurs, the life of the filter element is identified by comprehensively considering the water flow through the filter element, the water production time and the power-on time of the entire machine.

[0046] Step S103: If the flow meter does not show any abnormality, determine whether the filter element has expired based on the water flow rate and the power-on time of the whole machine.

[0047] Specifically, in the embodiment of the present invention, because the water flow rate can intuitively reflect the current working condition of the water purifier filter element, the greater the water flow rate, the shorter the life of the filter element. Therefore, when there is no abnormality in the flow meter, it is preferred to judge whether the filter element life has expired based on the water flow rate. At the same time, considering that the water purifier may have a small user water consumption or has not been used for a long time, at this time, although the water flow rate of the filter element is not large, the filter element may breed bacteria if used for too long, thereby affecting the water quality and being detrimental to the health of the user. Therefore, while identifying the life according to the water flow rate, judging whether the filter element life has expired based on the power-on time of the water purifier can further improve the accuracy of the filter element life identification.

[0048] Step S104: If the flow meter is abnormal, determine whether the life of the filter element has expired based on the water production time and the power-on time of the entire machine.

[0049] Specifically, in the embodiment of the present invention, although the water production time recorded by the filter element during the water purification process cannot directly reflect the working status of the filter element compared with the water flow rate, it can also indirectly reflect the current status of the filter element, that is, the longer the water production time, the greater the usage of the filter element, and the shorter the life of the filter element. Therefore, in the embodiment of the present invention, when an abnormality occurs in the flow meter, the filter element life is judged based on the water production time to see whether it has expired, which can avoid the situation where the flow meter abnormality cannot be identified and the filter element life is prompted. At the same time, it is still considered that the water purifier may have a small user water consumption or has not been used for a long time. At this time, although the water production time of the filter element does not increase much, the filter element has been used for too long. Therefore, while identifying the life according to the water production time, judging whether the filter element life is expired according to the power-on time of the water purifier can further improve the accuracy of the filter element life identification.

[0050] The method for identifying the life of a filter element provided in an embodiment of the present invention detects whether the flow meter has any abnormality during the operation of the filter element. If no abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water flow rate and the power-on time of the entire machine. If an abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water production time and the power-on time of the entire machine. By integrating the water flow rate, water production time, the power-on time of the entire machine and the status of the flow meter, the present invention can accurately identify the life of the filter element, avoid situations such as waste of the filter element due to unexpired life or excessive use affecting water quality, and thus improve user experience and satisfaction.

[0051] In this embodiment, a method for identifying the life of a filter element is provided, which can be used in the above-mentioned water purifier. Figure 2 FIG. 1 is a flow chart of a method for identifying the life of a filter element according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0052] Step S201: During the operation of the filter element, obtain the water flow rate, water production time and power-on time of the filter element. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0053] Step S202: Check whether the flow meter is abnormal. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0054] Step S203: If the flow meter does not show any abnormality, determine whether the filter element has expired based on the water flow rate and the power-on time of the whole machine.

[0055] Specifically, the above step S203 includes:

[0056] Step S2031, obtaining the rated water flow rate and rated power-on time of the filter element.

[0057] Specifically, in the embodiment of the present invention, after production, each filter element can determine the rated water flow rate and rated power-on time based on the filter element's filtration capacity. The maximum service life of the filter element after power-on is set according to the filter element drawing requirements, that is, the rated power-on time of the filter element is determined; the attenuation of the filter element water flow rate QB is tested under standard solution conditions based on the filter element material and area, and the entire system is used to obtain the attenuation slope k, and the initial water flow rate QB of the filter element is obtained at the same time. 初始 and minimum water flow rate QB 终止 , initial water flow rate QB 初始 The water flow rate of the new filter element, the minimum water flow rate QB 终止 The minimum flow rate required by the water purifier system is used to calculate the initial water flow rate QB 初始 and minimum water flow rate QB 终止The flow rate difference ΔQB between the two values ​​is taken, and the ratio of the flow rate difference ΔQB to the attenuation slope k is taken as the rated water flow rate L. The calculation formula is as follows:

[0058] L=(QB 初始 -QB 终止 ) / k=ΔQB / k

[0059] Step S2032, determining whether the water flow rate reaches the rated water flow rate, and if so, determining that the filter element has expired.

[0060] Specifically, in the embodiment of the present invention, Figure 3 As shown, the flow meter measures the real-time water flow l of the filter element and determines whether the water flow l exceeds the rated water flow L. If it exceeds, it is determined that the filter element has expired and a reminder to replace the filter element is issued to the user.

[0061] Step S2033: If not, the remaining water production time is determined based on the rated water flow, water flow rate and water production time, and whether the power-on time of the whole machine reaches the rated power-on time is judged. If it is reached, it is determined that the filter element life has expired.

[0062] Specifically, in the embodiment of the present invention, if the water flow rate l of the filter element does not exceed the rated water flow rate L, it proves that the filter element can still work normally at this time. However, due to the differences in water usage patterns of different users, some users have a large water consumption, so the power-on time of the whole machine is relatively short, while some users have a small water consumption, or may not be used for a long time, in which case the power-on time of the whole machine is relatively long. As long as the filter element is powered on and starts working, regardless of whether the water consumption is large or small, the probability of bacteria breeding will increase over time. Therefore, if Figure 3 As shown, in the embodiment of the present invention, when the water flow rate l does not exceed the rated water flow rate L, the power-on time t of the water purifier is set to 上电 Make a judgment, if the whole machine power-on time reaches the rated power-on time t 通电 , it is determined that the filter element life has expired. If not, it is operating normally.

[0063] In some optional implementations, in order to prevent the flow meter from being unable to determine whether the filter element is expired due to abnormality, the water production time t 制水 However, since the pump's operating capacity (water flow per unit time) will decrease during long-term operation, the lower the capacity, the slower the water production speed, resulting in a gradual increase in the time required to produce the same amount of water. Therefore. Figure 3 As shown, the embodiment of the present invention uses a flow meter to assist in real-time monitoring of the pump running time per unit flow, that is, the unit water production time t 单位 , correct the flow rate and calculation deviation caused by the reduction of pump operation capacity, that is, when there is no abnormality in the flow meter, update the remaining water production time t of the filter element in real time 剩余The calculation process is as follows: Calculate the difference between the rated water flow L and the water flow l to obtain the remaining water flow L 剩余 ; Calculate water production time t 制水 The ratio of the water flow rate l to the unit water production time t 单位 ; Calculate the remaining water volume L 剩余 and unit water production time t 单位 The product of the remaining water production time t 剩余 , the calculation formula is as follows:

[0064]

[0065] The method for identifying the life of a filter element provided in an embodiment of the present invention detects whether the flow meter has any abnormality during the operation of the filter element. If no abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water flow rate and the power-on time of the entire machine. If an abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water production time and the power-on time of the entire machine. By integrating the water flow rate, water production time, the power-on time of the entire machine and the status of the flow meter, the present invention can accurately identify the life of the filter element, avoid situations such as waste of the filter element due to unexpired life or excessive use affecting water quality, and thus improve user experience and satisfaction.

[0066] In this embodiment, a method for identifying the life of a filter element is provided, which can be used in the above-mentioned water purifier. Figure 4 FIG. 1 is a flow chart of a method for identifying the life of a filter element according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0067] Step S401: During the operation of the filter element, obtain the water flow rate, water production time and power-on time of the filter element. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0068] Step S402: Check whether the flow meter is abnormal. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0069] Step S403: If the flow meter is abnormal, determine whether the life of the filter element has expired based on the water production time and the power-on time of the entire machine.

[0070] Specifically, the above step S403 includes:

[0071] Step S4031, obtaining the remaining water production time.

[0072] Specifically, in the embodiment of the present invention, when the flow meter is normal, the rated water flow L, the water flow l and the water production time t 制水 Real-time update of remaining water production time t剩余 Therefore, when the flow meter is abnormal, the latest remaining water production time t can be obtained. 剩余 , this time is determined based on the current pump operating capacity.

[0073] Step S4032, determining whether the water production time reaches the remaining water production time, and if so, determining that the filter element has expired.

[0074] Specifically, in the embodiment of the present invention, Figure 3 As shown, when the filter element life cannot be identified based on the water flow rate, the water production time t 制水 Whether the remaining water production time t is exceeded 剩余 To determine whether the filter element has expired. 制水 Exceeding the remaining water production time t 剩余 , which proves that the filter element has been working for a long time and can no longer meet user needs. The filter element is judged to have expired and the user is prompted to replace the element.

[0075] Step S4033: If not, determine whether the power-on time of the whole machine has reached the rated power-on time. If so, determine that the filter element life has expired. Figure 2 Step S2033 of the illustrated embodiment will not be described in detail here.

[0076] Step S404: If the flow meter returns to normal, the process returns to the step of detecting whether the flow meter is abnormal. If the flow meter is not abnormal, the process determines whether the life of the filter element has expired based on the water flow rate and the power-on time of the entire machine.

[0077] Specifically, in this embodiment of the present invention, if the flow meter malfunctions, the water purifier will remind the user to replace the flow meter. After the flow meter is replaced, the water flow measurement of the filter element will be restored, and the filter element life span will be determined based on the water flow rate and the power-on time of the entire system.

[0078] The method for identifying the life of a filter element provided in an embodiment of the present invention detects whether the flow meter has any abnormality during the operation of the filter element. If no abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water flow rate and the power-on time of the entire machine. If an abnormality occurs, the method determines whether the life of the filter element has expired based on the obtained water production time and the power-on time of the entire machine. By integrating the water flow rate, water production time, the power-on time of the entire machine and the status of the flow meter, the present invention can accurately identify the life of the filter element, avoid situations such as waste of the filter element due to unexpired life or excessive use affecting water quality, and thus improve user experience and satisfaction.
