However, as the equipment runs for a longer time, the water pump will inevitably age, and its flow rate performance will decrease accordingly. At this time, there is a lack of real-time monitoring and adjustment mechanism for the actual flow rate of the water pump.

[0058] In order to make the features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0059] The terms "first", "second", "third", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0060] In order to overcome the problem of water output control deviation after the above-mentioned water pump is aged, a closed-loop control system based on flow sensor feedback has also been proposed in the relevant technology. The system monitors the water output of the drinking water equipment in real time by installing a flow sensor, and adjusts the operating status of the water pump according to the actual flow feedback, so as to achieve accurate statistics of the water output and quantitative water supply. However, this solution also faces some challenges. First, the flow sensor may not be able to accurately distinguish whether there is water flowing in the current pipeline during the detection process, which may lead to measurement deviations in some cases. Secondly, high-quality flow sensors and their related maintenance costs are high, which increases the overall manufacturing cost and subsequent maintenance burden of drinking water equipment. Therefore, while pursuing high-precision control, how to balance cost and performance becomes a key issue that needs to be solved in this solution.

[0061] Based on this, an embodiment of the present application provides a water pump flow rate self-calibration method, by first counting the current cumulative working time corresponding to the water pump when the current water level of the water tank changes from the first water level to the second water level, the second water level is lower than the first water level; then, based on the current cumulative working time and the corresponding interval water volume between the first water level and the second water level in the water tank, the current actual flow rate of the water pump is calibrated. Compared with the closed-loop control system based on the flow sensor in the related art, the embodiment of the present application does not require an additional flow sensor, nor does it require complex hardware or software support, so that the drinking water equipment can accurately evaluate and adjust the performance of the water pump through a simple calculation and calibration process, and realize self-calibration of the actual flow rate of the water pump, which can reduce the manufacturing cost and subsequent maintenance cost of the drinking water equipment, making the self-calibration function of the water pump flow rate in the drinking water equipment easier to apply and promote on the existing drinking water equipment, and can avoid the problem of reduced performance of the drinking water equipment due to water pump aging or other factors, thereby improving the overall performance and user experience of the drinking water equipment.

[0062] Please refer to the following Figure 1 , which is a schematic diagram of the structure of a drinking water device provided by an exemplary embodiment of the present application. Figure 1 As shown, the drinking water equipment at least includes a water tank 110 and a water pump 120. Among them:

[0063] The water tank 110 is used to store water. A first water level detection element 130 and a second water level detection element 140 are installed in the water tank 110. The first water level detection element 130 is located at a first water point of the water tank 110, and the second water level detection element 140 is located at a second water point of the water tank 110. The height corresponding to the first water point (first water level) and the height corresponding to the second water point (second water level) can be set according to actual needs, and the embodiment of the present application does not limit this.

[0064] Specifically, the first water level detection element 130 is used to detect the height relationship between the current water level in the water tank 110 and the first water level, and the second water level detection element 140 is used to detect the height relationship between the current water level in the water tank 110 and the second water level; the second water level is lower than the first water level.

[0065] It can be understood that the above-mentioned first water level detection element 130 can be but not limited to a high float in the water tank 110, and the second water level detection element 140 can be but not limited to a low float in the water tank 110, and can be but not limited to a high float in the water tank 110. The above-mentioned first water level detection element 130 and the second water level detection element 140 can be but not limited to using at least one method such as a reed switch, a Hall sensor, a capacitive sensor, etc. to respectively correspond to the height relationship between the current water level in the water tank 110 and the first water level and the second water level.

[0066] The water tank 110 is connected to the water inlet 160 through a water inlet passage. The water inlet passage includes a water inlet switch 150 and a pipe 180. The water inlet switch 150 is used to control the opening or closing of the water inlet passage. When the water inlet switch 150 is in an open state, the water inlet passage is connected, i.e., opened, and the water tank 110 can be replenished with water that needs to be stored from the water inlet 160 through the water inlet passage, and the water level in the water tank 110 will continue to rise; when the water inlet switch 150 is in a closed state, the water inlet passage is interrupted, i.e., closed, and the water level in the water tank 110 will no longer rise.

[0067] The water pump 120 is connected to the water tank 110 through a pipeline, and is used to pump water in the water tank 110 to the water outlet 170 .

[0068] Optionally, the structure of the water tank 110 may be, but is not limited to, cylindrical, rectangular, cube, or a special shape.

[0069] Specifically, after the drinking water equipment is used after leaving the factory, the current cumulative working time corresponding to the water pump when the current water level of the water tank changes from the first water level to the second water level can be counted, and the current actual flow rate of the water pump can be calibrated directly based on the above-mentioned current cumulative working time and the interval water volume corresponding to the above-mentioned first water level and the above-mentioned second water level in the above-mentioned water tank.

[0070] Understandably, Figure 1 The number, shape, connection method, etc. of each component in the drinking water device shown are only examples, and the embodiments of this specification do not specifically limit this.

[0071] Next, combine Figure 1 , taking the controller or processor of a drinking water device executing a water pump flow rate self-calibration as an example, a water pump flow rate self-calibration method provided by an exemplary embodiment of the present application is introduced. For details, please refer to Figure 2, which is a flow chart of a water pump flow rate self-calibration method provided by an exemplary embodiment of the present application. Figure 2 As shown, the water pump flow rate self-calibration method includes the following steps:

[0072] S201, counting the current accumulated working time of the water pump when the current water level of the water tank changes from a first water level to a second water level, wherein the second water level is lower than the first water level.

[0073] Specifically, when the water pump starts working, the water level change in the water tank can be monitored in real time through the water level detection element, and the current cumulative working time (current cumulative working time) of the water pump during the process of the current water level in the water tank changing from the first water level to the second water level can be counted using a timer or time recording function. The above-mentioned current cumulative working time is the total working time of the water pump from the first water level of the water tank to the current water level dropping to the second water level. The above-mentioned current water level is used to characterize the current water level height in the water tank of the drinking water equipment.

[0074] Optionally, the above S201, the implementation process of counting the current accumulated working time corresponding to the water pump when the current water level of the water tank changes from the first water level to the second water level may include but is not limited to: periodically counting the current accumulated working time corresponding to the water pump when the current water level of the water tank changes from the first water level to the second water level, for example but not limited to automatically triggering the statistics of the current accumulated working time corresponding to the water pump and the self-calibration of the water pump flow rate at every preset time period (for example but not limited to daily, weekly, monthly, etc.), so as to realize the function of self-calibration of flow rate of the drinking water equipment without flow sensor at low cost and high efficiency, and improve the overall performance and use experience of the drinking water equipment; or, when the user feels that there is a quantitative deviation or a water consumption statistical deviation during the use of the drinking water equipment, the flow rate calibration instruction may be triggered through but is not limited to the display screen of the drinking water equipment or a terminal or server connected to the drinking water equipment for communication. After receiving the flow rate calibration instruction, the drinking water equipment may respond to the flow rate calibration instruction to count the current accumulated working time corresponding to the water pump when the current water level of the water tank changes from the first water level to the second water level, so as to meet the calibration needs of the user. That is, the embodiment of the present application can calibrate the flow rate of the water pump regularly or on demand, so as to promptly detect and correct changes in the performance of the water pump, thereby enhancing the stability and reliability of the entire drinking water equipment.

[0075] S202: Calibrate the current actual flow rate of the water pump based on the current accumulated working time and the water volume of the interval corresponding to the first water level and the second water level in the water tank.

[0076] Specifically, the above-mentioned interval water volume is calculated based on the initial flow rate and the initial cumulative working time of the water pump, that is, the product of the above-mentioned initial flow rate and the initial cumulative working time. The above-mentioned initial cumulative working time is the cumulative working time corresponding to the water pump during the process when the water level of the water tank changes from the first water level to the second water level when the cumulative use time of the drinking water equipment is less than or equal to the preset time (for example, but not limited to 0, 24 hours, 1 month, 1 year, etc.). After obtaining the current cumulative working time corresponding to the water pump during the process when the current water level of the water tank changes from the first water level to the second water level, the interval water volume corresponding to the first water level and the second water level in the water tank that have been calculated in advance can be read first, and then the current actual flow rate of the water pump can be directly calculated by the formula = interval water volume / current cumulative working time. The above-mentioned current actual flow rate is the actual flow rate of the water pump under the current working conditions. The above-mentioned interval water volume is calculated based on the initial flow rate of the water pump and the historical cumulative working time. The above-mentioned historical cumulative working time is the cumulative working time corresponding to the water pump during the process when the current water level of the water tank changes from the first water level to the second water level, which is counted before the above-mentioned current cumulative working time. For example, but not limited to, the cumulative working time corresponding to the water pump during the process when the current water level of the water tank changes from the first water level to the second water level when the drinking water equipment is used for the first time.

[0077] Optionally, when the cumulative usage time of the drinking water equipment is less than or equal to the preset time, it means that the drinking water equipment is used for the first time or has not been used for a long time. At this time, the water pump of the drinking water equipment has not aged and its flow rate performance has not decreased. Then, the current actual flow rate of the water pump can be directly determined as the initial flow rate. The above initial flow rate is obtained by measuring the flow rate of the water pump in the drinking water equipment in the new machine state by the flow measurement device. The above new machine state is used to characterize the state of the drinking water equipment before leaving the factory or the state that has not been used. The above-mentioned implementation process of calibrating the current actual flow rate of the water pump based on the current cumulative working time and the interval water volume may include but is not limited to: when the cumulative use time of the drinking water equipment is greater than the preset time, it means that the water pump of the drinking water equipment has been used for a long time, and there may be aging that causes its flow rate performance to decrease, then the current flow rate value of the water pump = interval water volume / current cumulative working time will be determined based on the above-mentioned current cumulative working time and interval water volume; then, the current actual flow rate of the water pump is directly updated to the above-mentioned current flow rate value, that is, when the current flow rate value is inconsistent with the initial flow rate, it means that the current actual flow rate of the water pump of the drinking water equipment has changed compared to the initial flow rate in the new machine state, then the current actual The actual flow rate is updated from the initial flow rate to the above-mentioned current flow rate value to realize self-calibration of the water pump flow rate; when the current flow rate value is consistent with the initial flow rate, it means that the current actual flow rate of the drinking water equipment water pump has not changed compared with the initial flow rate in the new machine state, or when the cumulative usage time of the drinking water equipment is not greater than the preset time, it means that the drinking water equipment is used for the first time or has not been used for a long time, and the water pump of the drinking water equipment will not have the problem of aging affecting the flow rate. In this way, the current actual flow rate of the water pump can continue to be maintained at the initial flow rate, avoiding the problem of invalid flow rate calibration when the drinking water equipment is used for the first time or when the water pump is not aged to affect the flow rate, thereby improving the effectiveness of the water pump flow rate self-calibration and avoiding the waste of computing resources of the drinking water equipment.

[0078] In the embodiment of the present application, the current cumulative working time corresponding to the water pump in the process of the current water level of the water tank changing from the first water level to the second water level is first counted, and the second water level is lower than the first water level; then, the current actual flow rate of the water pump is calibrated based on the current cumulative working time and the corresponding interval water volume between the first water level and the second water level in the water tank. Compared with the closed-loop control system based on the flow sensor in the related art, the embodiment of the present application does not require an additional flow sensor, nor does it require complex hardware or software support, so that the drinking water equipment can accurately evaluate and adjust the performance of the water pump through a simple calculation and calibration process, and realize self-calibration of the actual flow rate of the water pump, which can reduce the manufacturing cost and subsequent maintenance cost of the drinking water equipment, making the self-calibration function of the water pump flow rate in the drinking water equipment easier to apply and promote on the existing drinking water equipment, and can avoid the problem of reduced performance of the drinking water equipment due to aging of the water pump or other factors, thereby improving the overall performance of the drinking water equipment and user experience.

[0079] In some possible embodiments, after the current actual flow rate of the water pump is calibrated based on the current accumulated working time and the water volume in the interval corresponding to the first water level and the second water level in the water tank, the water pump flow rate self-calibration method may also include but is not limited to: counting the current water output of the drinking water equipment according to the current actual flow rate and the current working time of the calibrated water pump, or determining the specified working time according to the current actual flow rate and the specified water output of the calibrated water pump, and controlling the water pump to stop working after working for the specified working time.

[0080] Specifically, the above-mentioned current working time refers to the time from the start of the water pump to the current moment. The current water output of the drinking water equipment refers to the amount of water pumped out and delivered from the water tank during the current working time, and is an important parameter for evaluating the performance of the drinking water equipment. After the current actual flow rate of the water pump is calibrated, when the user uses the drinking water equipment to draw water again, the drinking water equipment can record the current working time of the water pump through a timer or clock, and then directly calculate the current water output of the water pump during the current working time based on the product of the calibrated current actual flow rate and the current working time. Thus, the current water output of the drinking water equipment can be accurately calculated through the precise current actual flow rate and current working time of the water pump, avoiding excessive or insufficient water delivery and improving the working efficiency of the drinking water equipment.

[0081] Specifically, the above-mentioned designated water output refers to the amount of water that needs to be delivered by the water pump as set by the user or the system. The above-mentioned designated working time refers to the time the water pump needs to work, which is calculated based on the current actual flow rate of the water pump and the designated water output. After the drinking water equipment obtains the designated water output through user input or system setting, it can calculate the designated working time required for the water pump through division operation based on the designated water output and the current actual flow rate of the calibrated water pump. Then, the working time of the water pump can be set through the controller or timer, and the water pump can be started to work. When the water pump has been working for a specified time, the controller or timer sends a stop signal to stop the water pump.

[0082] In the embodiments of the present application, on the one hand, the user can set a specified water output according to actual needs, and the drinking water equipment automatically calculates and controls the working time of the water pump according to the settings, thereby meeting the user's personalized needs; on the other hand, the working time of the water pump can be accurately controlled to avoid long-term ineffective operation of the water pump, thereby reducing energy consumption and wear and tear and extending the service life of the water pump; on yet another hand, automatic and intelligent water output control and management can be achieved to improve the overall performance and user experience of the drinking water equipment.

[0083] Please refer to the following Figure 3 , which is a flow chart of another water pump flow rate self-calibration method provided by an exemplary embodiment of the present application. Figure 3 As shown, the water pump flow rate self-calibration method includes the following steps:

[0084] S301, counting the current accumulated working time of the water pump when the current water level of the water tank changes from a first water level to a second water level, wherein the second water level is lower than the first water level.

[0085] Specifically, the above S301 is consistent with S201 and will not be repeated here.

[0086] S302: When the water volume of the interval corresponding to the first water level and the second water level in the water tank is in a known state, calibrate the current actual flow rate of the water pump based on the current accumulated working time and the water volume of the interval.

[0087] Specifically, when the water volume of the interval corresponding to the first water level and the second water level in the water tank is in a known state, it means that the water volume of the interval corresponding to the water tank has been calculated and pre-stored in the database after the user has used the drinking water device, and the pre-stored water volume of the interval in the database can be directly read to participate in the calibration of the water pump flow rate. The calibration process in the above S302 is consistent with S202 and will not be repeated here.

[0088] Please continue to refer to Figure 3 ,like Figure 3As shown, in the above S301, after counting the current accumulated working time of the water pump corresponding to the process in which the current water level of the water tank changes from the first water level to the second water level, the water pump flow rate self-calibration method may also include but is not limited to:

[0089] S303, when the interval water volume corresponding to the first water level and the second water level is in an unknown state, the interval water volume is determined based on the initial flow rate of the water pump and the current accumulated working time, and the interval water volume is marked as a known state.

[0090] Specifically, when the interval water volume corresponding to the first water level and the second water level is in an unknown state, it means that the drinking water equipment has not yet calculated the interval water volume. Then, it is necessary to determine the interval water volume based on the initial flow rate of the water pump and the current cumulative working time, that is, the interval water volume is equal to the product of the initial flow rate of the water pump and the current cumulative working time, and mark the interval water volume as a known state, so that there is no need to perform special measurement or design of the interval water volume of the water tank in advance. It can not only realize the non-sensing calculation corresponding to the interval water volume of the water tank of the drinking water equipment during the user's use, but also provide parameter support for the flow rate calibration of the water pump after the subsequent long-term use of the drinking water equipment. There is no need to perform special calibration checks on the drinking water equipment, and the water pump flow rate self-calibration can be completed during the normal use of the drinking water equipment by the user. The above initial flow rate is obtained by measuring the flow rate of the water pump in the drinking water equipment in the new machine state by the flow measurement device.

[0091] Furthermore, when the interval water volume corresponding to the first water level and the second water level is in an unknown state and the cumulative usage time of the drinking water equipment is less than or equal to the preset time, it means that the drinking water equipment is used for the first time or the usage time is not long, and the interval water volume has not been calculated. At this time, the water pump of the drinking water equipment has not aged, and its flow rate performance has not decreased, so flow rate calibration is not required, but preparations are needed for subsequent flow rate calibration, that is, the interval water volume needs to be determined based on the initial flow rate of the water pump and the current cumulative working time, that is, the interval water volume is equal to the product of the initial flow rate of the water pump and the current cumulative working time, and the interval water volume is marked as a known state.

[0092] Alternatively, if Figure 4As shown, before the production of the drinking water equipment, the initial flow rate of the water pump 120 of the drinking water equipment can be actually measured by the flow measurement tooling 420, for example but not limited to first connecting the water pump 120 of the drinking water equipment and the flow sensor 421 of the flow measurement tooling 420 through the waterway, and communicating the controller 410 of the drinking water equipment and the tooling controller 422 of the flow measurement tooling 420. The tooling controller 422 sends a water output instruction to the controller 410 of the drinking water equipment, so that the controller 410 of the drinking water equipment controls the water pump 120 to work, so that water flow is generated in the waterway. After the flow sensor 421 records the water flow in the waterway, it is transmitted back to the tooling controller 422. After the tooling controller 422 obtains the water flow, it sends a water stop instruction to the controller 410 of the drinking water equipment, so that the controller 410 of the drinking water equipment controls the water pump 120 to stop working, and calculates the initial flow rate of the water pump according to the water flow and the water flow duration. Then, the initial flow rate of the water pump is sent to the controller 410 of the drinking water equipment. After the drinking water device receives the initial flow rate sent by the flow measurement device, it can directly save the initial flow rate in the database, so that when the drinking water device is used subsequently when the interval water volume is unknown, the initial flow rate of the water pump can be directly read from the database to calculate the interval water volume.

[0093] Please refer to the following Figure 5 , which is a flow chart of another water pump flow rate self-calibration method provided by an exemplary embodiment of the present application. Figure 5 As shown, the water pump flow rate self-calibration method includes the following steps:

[0094] S501, detecting whether the current water level of the water tank is higher than or equal to the first water level.

[0095] Specifically, after the drinking water equipment is powered on, the first water level detection element (for example, but not limited to a float sensor, a pressure sensor, an ultrasonic sensor, a reed switch, a Hall sensor, a capacitive sensing element, etc.) located at the first water point in the water tank can be used to detect the height relationship between the water level in the water tank and the first water level in real time or periodically, thereby determining whether there is sufficient water in the water tank and whether it is necessary to add water before use.

[0096] S502: If the current water level is higher than or equal to the first water level, the water inlet passage is closed.

[0097] Specifically, after the drinking water device is powered on, if it is detected that the current water level of the water tank is higher than or equal to the first water level, it means that the water in the water tank is sufficient and no more water is needed, then the water inlet switch of the water inlet passage can be controlled to be closed to close the water inlet passage, thereby stopping the water inlet of the water tank. The above-mentioned water inlet passage refers to the path for water to enter the water tank from the outside, such as but not limited to components including a water inlet switch (such as a water inlet valve), a pipe, etc.

[0098] Please continue to refer to Figure 5 ,like Figure 5 As shown, after the above S501, detecting whether the current water level of the water tank is higher than or equal to the first water level, the method may also include but is not limited to:

[0099] S503, if the current water level is lower than the first water level, the water inlet passage is opened until it is detected that the current water level of the water tank is higher than or equal to the first water level and then the water inlet passage is closed.

[0100] Specifically, after the drinking water device is powered on, if it is detected that the current water level of the water tank is lower than the first water level, it means that the water in the water tank is insufficient and water needs to be added before use. Then, the water inlet switch of the water inlet passage can be controlled to open to open the water inlet passage and allow water to enter the water tank. At the same time, the current water level of the water tank is continuously detected by the first water level detection element until it is detected that the current water level reaches or exceeds the first water level, and then the water inlet switch of the water inlet passage is controlled to close to close the water inlet passage.

[0101] S504, when it is detected that the current water level of the water tank changes from a state higher than or equal to the first water level to a state lower than the first water level, start counting the current accumulated working time of the water pump.

[0102] Specifically, when a user uses the drinking water device to normally draw water, the controller of the drinking water device controls the operation of the water pump. The first water level detection element detects the height relationship between the current water level of the water tank and the first water level in real time or at a preset frequency. When it is detected that the current water level drops from being higher than or equal to the first water level to being lower than the first water level, the timer of the drinking water device is triggered to start recording the working time of the water pump. The above-mentioned current cumulative working time is the cumulative working time of the water pump from the time when the current water level becomes lower than the first water level to the current moment, which is used for subsequent flow rate calibration.

[0103] S505, when it is detected that the current water level changes from a state higher than or equal to the second water level to a state lower than the second water level, the counting of the current accumulated working time of the water pump ends.

[0104] Specifically, when the user uses the drinking water device to normally draw water, the second water level detection element will also be used to detect the height relationship between the current water level of the water tank and the second water level in real time or at a preset frequency. When it is detected that the current water level drops from being higher than or equal to the second water level to being lower than the second water level, the timer of the drinking water device is triggered to stop recording the working time of the water pump, and the current cumulative working time of the water pump is counted. The above-mentioned current cumulative working time is the cumulative working time of the water pump from the time when the current water level becomes lower than the first water level to the time when the current water level becomes lower than the second water level, which is used for subsequent flow rate calibration.

[0105] Optionally, during the above-mentioned statistical process of the current cumulative working time, the water inlet passage will be controlled to remain in a closed state to ensure that the current cumulative working time corresponding to the water pump during the process in which the current water level of the water tank changes from the first water level to the second water level can be accurately counted. When the current water level of the water tank is lower than the second water level, the water inlet passage will be opened until it is detected that the current water level of the water tank is higher than or equal to the first water level, and then the water inlet passage will be closed, thereby avoiding the idling of the water pump and allowing the drinking water device to automatically fill and store water after the user has taken the water stored in the water tank, thereby improving the intelligence and flexibility of the drinking water device.

[0106] S506, determining whether the water volume in the interval corresponding to the first water level and the second water level in the water tank is in a known state.

[0107] Specifically, after obtaining the current cumulative working time of the water pump, the interval water volume can be directly read from the database. If the reading is successful, it can be determined that the interval water volume corresponding to the first water level and the second water level in the water tank is in a known state; if the reading fails, it can be determined that the interval water volume corresponding to the first water level and the second water level in the water tank is in an unknown state.

[0108] S507, when the water volume of the interval corresponding to the first water level and the second water level in the water tank is in a known state, calibrate the current actual flow rate of the water pump based on the current accumulated working time and the water volume of the interval.

[0109] Specifically, the above S507 is consistent with S202 and will not be repeated here.

[0110] Please continue to refer to Figure 5 ,like Figure 5 As shown, in the above S506, after determining whether the water volume in the interval corresponding to the first water level and the second water level in the water tank is in a known state, the water pump flow rate self-calibration method may also include but is not limited to:

[0111] S508, when the interval water volume corresponding to the first water level and the second water level is in an unknown state, the interval water volume is determined based on the initial flow rate of the water pump and the current accumulated working time, and the interval water volume is marked as a known state.

[0112] Specifically, the above S508 is consistent with S303 and will not be described again. After marking the interval water volume as a known state, in the subsequent use of the drinking water device, the water pump flow rate self-calibration can be performed with reference to, but not limited to, the above S501-S507.

[0113] Please refer to the following Figure 8 , which is a flow chart of a control method for a drinking water device provided by an exemplary embodiment of the present application. Figure 8As shown, the control method of the drinking water equipment may include but is not limited to the following steps:

[0114] S601, receiving a water fetching instruction.

[0115] Specifically, the water extraction instruction refers to a request issued by a user through a user interface of the drinking water device (such as but not limited to a button, a touch screen, a mobile phone APP, etc.), requiring the drinking water device to provide a certain amount of drinking water. That is, the user triggers the water extraction instruction through the user interface, and the water extraction instruction, for example but not limited to, carries a specified water extraction amount or a specified water extraction time. After the controller of the drinking water device receives and parses the water extraction instruction, it can prepare to execute the corresponding water extraction operation.

[0116] S602, in response to the water intake instruction, when the current water level is higher than the second water level, controlling the water pump to operate.

[0117] Specifically, after receiving the water extraction instruction, it will first detect whether the current water level in the water tank is higher than the second water level. If the current water level is higher than the second water level, it means that there is a certain amount of water in the water tank for the user to use, and then the water pump will be started to start the water extraction operation, thereby avoiding the problem of the water pump running idle and overheating when the current water level in the water tank is low, which affects the service life of the drinking water equipment, and extending the service life of the drinking water equipment.

[0118] Optionally, if it is detected that the current water level is lower than or equal to the second water level, a warning can be directly issued or the user can be prompted that the water tank is short of water and it is not suitable for water extraction operation at present, that is, the water pump will not be started first.

[0119] S603, when it is detected that the drinking water equipment meets the target condition, the water pump is controlled to stop working.

[0120] Specifically, the above target conditions are used to characterize the stop conditions that the drinking water equipment needs to meet during the water extraction process. The above target conditions may include, but are not limited to, one of the following: the current water level is lower than the second water level (indicating that the water in the water tank is about to be taken out), the cumulative water output of the water pump after the current water level changes from higher than or equal to the second water level to lower than the second water level reaches the target water output or the cumulative water output time reaches the target water output time (indicating that the water in the water tank has been taken out and can no longer be extracted). The target water output is used to characterize the maximum water output that the water pump can extract at the second water level. The above target water output time may be, but is not limited to, calculated based on the current actual flow rate of the water pump and the target water output.

[0121] In the embodiment of the present application, when it is detected that the drinking water equipment meets the target conditions, the water pump is controlled to stop working, that is, water extraction is automatically stopped when the water level in the water tank is too low, thereby avoiding faults such as water pump idling and overheating, extending the service life of the equipment, and improving the intelligence level and management efficiency of the drinking water equipment.

[0170] In some possible embodiments, the water tank includes a water inlet passage; the processor 810 executes the above-mentioned when it is detected that the current water level of the water tank changes from a state higher than or equal to the first water level to a state lower than the first water level, before starting to count the current accumulated working time of the water pump, and is further used to execute:

[0171] Detect whether the current water level of the water tank is higher than or equal to the first water level; if so, close the water inlet passage; if not, open the water inlet passage until it is detected that the current water level of the water tank is higher than or equal to the first water level and then close the water inlet passage.
