Description

Technical Field

[0001] The present specification relates to the technical field of tea bar machines, and in particular to a waterproof control method for a bottom-inlet tea bar machine. Background Art

[0002] As a common drinking water device, the design of the water inlet method of the tea bar machine is directly related to the user experience and the reliability of the equipment. Traditional tea bar machines generally adopt the upper water inlet method. Although this design meets the basic water intake needs to a certain extent, it has many disadvantages. The main problems of the upper water inlet method are water splashing and cumbersome manual operation. During the water inlet process, due to the large impact of the water flow, it is easy to splash water, affecting the overall aesthetics of the equipment and may also cause pollution to the surrounding environment. In addition, the user needs to manually open the lid of the pot to take water. This operation is not only cumbersome, but may also cause safety hazards such as scalding due to improper operation. In order to solve these problems, the lower water inlet tea bar machine came into being. The lower water inlet tea bar machine realizes the function of directly taking water from the bucket to the heating pot by setting a coupler that inlets water from the bottom, effectively avoiding the problems of water splashing and manual lid opening caused by the upper water inlet method, and greatly improving the user experience. The user only needs to place the kettle on the coupler to automatically complete the water taking process without manual operation, which is convenient and safe.

[0003] However, when the user lifts the kettle during the water intake process, a small amount of water will spray into the coupler. If the water contacts the electronic components such as NTC (negative temperature coefficient thermistor) in the coupler, it may cause a short circuit and failure. As an important temperature sensor in the tea bar machine, the failure of NTC will directly affect the normal operation of the equipment, such as inaccurate heating temperature and failure of the protection mechanism. During the water intake process of the tea bar machine, the water pump is turned on. If the kettle is lifted during this process, the water pump must be immediately turned off to stop the water discharge, otherwise it will cause water to splash through the coupler and flow into the coupler, causing the NTC to fail. The main reason for the water inflow of the lower water inlet coupler is that during the operation of the water pump, the kettle is manually lifted, resulting in the moment of lifting, the water pump has not completely stopped working, and a small amount of water is sprayed into the coupler. In summary, during the use of the lower water inlet tea bar machine, the operation of manually lifting the kettle will lead to the risk of the coupler contacting water and failing, affecting the normal operation of the tea bar machine. Summary of the invention

[0020] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0021] The embodiment of this specification provides a waterproof control method for a bottom-inlet tea bar machine. It should be noted that the execution subject in the embodiment of this specification can be a server or any device with data processing capabilities. Figure 1 A schematic flow chart of a waterproof control method for a bottom water inlet tea bar machine provided in an embodiment of this specification, such as Figure 1 As shown, it mainly includes the following steps:

[0022] Step S101, determining the current voltage detection cycle corresponding to the temperature sensor of the tea bar machine.

[0023] During the water intake process of the tea bar machine, the water pump is turned on. If the kettle is lifted during this process, the water pump must be immediately turned off to stop discharging water, otherwise water will splash out through the coupler and flow into the coupler, causing NTC failure. Figure 2 The following is a schematic diagram of a water intake scenario of a bottom-inlet tea bar machine provided in an embodiment of this specification. A temperature sensor is provided at the bottom of the tea bar machine pot body, such as Figure 2 As shown, the temperature sensor is a negative temperature coefficient (NTC) temperature sensor. A coupler assembly is arranged at the bottom of the kettle body. The bottom of the kettle body is an upper coupler assembly, and the bottom of the kettle body is a lower coupler assembly. The coupler assembly is connected to a water pump to form a water circuit. The water pump is used to pump water to the water storage device. The NTC temperature sensor is connected to the main control board through the coupler iron sheet terminal. When the kettle is placed on the base normally, the coupler iron sheet terminals are in close contact to ensure that the circuit between the NTC temperature sensor and the main control board is unobstructed. When the kettle is lifted, the connection between the coupler iron sheet terminals is disconnected, resulting in a circuit interruption between the NTC temperature sensor and the main control board. The main control board can determine that the kettle has been lifted by detecting this circuit interruption signal. Since the control command to turn off the water pump is almost sent and controlled in real time, the influence of this time length can be almost ignored. Therefore, in order to control the water pump to be turned off at the moment the kettle is lifted, it is necessary to strictly control the detection cycle of the kettle lifting detection to ensure that the kettle is detected to be lifted within this detection cycle, so as to shorten the time between the actual kettle lifting operation and the detection board detecting the kettle lifting.

[0024] During the research on the bottom-inlet tea bar machine, experiments were conducted on the water pump voltage and NTC voltage. It was found that for a certain type of NTC temperature sensor, when the kettle is lifted, the main control board detects that the time from NTC disconnection to the water pump stopping is 20ms. In other words, if you want to turn off the water pump at the moment the kettle is lifted, you need to shorten the control time from NTC disconnection to water pump stopping to less than 20ms. If the time between NTC disconnection detection and water pump stopping exceeds 20ms, residual water will spray into the coupler at the moment the kettle is lifted, causing NTC detection failure. However, for tea bar machines equipped with different types of temperature sensors, the time from the main control board detecting the temperature sensor disconnection to the water pump stopping at the moment the kettle is lifted is different. Therefore, it is necessary to determine the current voltage detection cycle corresponding to the temperature sensor in each tea bar machine.

[0025] Determining a current voltage detection cycle corresponding to the temperature sensor of the tea bar machine specifically includes: obtaining a waterproof control time threshold corresponding to the tea bar machine; and determining a current voltage detection cycle corresponding to the temperature sensor through the waterproof control time threshold.

[0026] In one embodiment of the present specification, the waterproof control time threshold corresponding to the tea bar machine is obtained. The waterproof control time threshold here refers to the total time from when the kettle is lifted to when the water pump starts to shut down. During the water fetching process, even if the kettle is lifted quickly by humans, the water pump can be controlled to shut down quickly, and the residual water will not spray into the coupler to cause NTC failure. Through this waterproof control time threshold, the current voltage detection cycle corresponding to the temperature sensor is determined to ensure that the kettle lifting operation can be detected within the current voltage detection cycle.

[0027] Obtaining the waterproof control time threshold corresponding to the tea bar machine specifically includes: obtaining sensor specification data corresponding to the temperature sensor of the tea bar machine, and determining a kettle lifting test parameter set based on the sensor specification data, wherein the kettle lifting test parameter set includes sensor voltage acquisition parameters and water pump voltage acquisition parameters; performing a kettle lifting test on the tea bar machine according to the kettle lifting test parameter set, and collecting sensor voltage detection data and water pump voltage detection data; analyzing the sensor voltage detection data and the water pump voltage detection data to determine the waterproof control time threshold corresponding to the tea bar machine.

[0028] There are differences in the types of temperature sensors built into different tea bar machines, which leads to different temperature sensor acquisition accuracy. In this context, there are differences in the waterproof control time thresholds corresponding to different tea bar machines. When determining the waterproof control time threshold corresponding to the tea bar machine, it is necessary to test the tea bar machine as a whole. During the test, the test data collected after manual pot lifting operation is used to obtain the waterproof control time threshold corresponding to the tea bar machine. Before conducting the whole machine test, it is necessary to set the test parameter set according to the type of temperature sensor in different tea bar machines.

[0029] First, obtain the sensor specification data corresponding to the temperature sensor of the tea bar machine. Different sensor specifications correspond to different sensor accuracies and corresponding voltage acquisition parameters. In addition, in addition to determining the acquisition parameters of the sensor voltage during the whole machine test, since the waterproof control time threshold that needs to be determined is the time threshold from detecting the kettle being lifted to the water pump starting to shut down, it is also necessary to determine the acquisition period of the water pump voltage. The acquisition parameters of the water pump voltage are closely related to the sensor acquisition parameters. Using the sensor accuracy in the sensor specification data, determine the kettle lifting test parameter set, which includes the sensor voltage acquisition parameters and the water pump voltage acquisition parameters.

[0030] After determining the above-mentioned kettle test parameter set, build a whole machine test environment for the tea bar machine. When conducting the whole machine test here, you can set up an external probe, one end of an external probe is connected to the water pump, and the other end is grounded; one end of the other external probe is connected to the temperature sensor, and the other end is grounded. After the tea bar machine is powered on, control the water pump to take water. At the same time, use two external probes and high-precision data acquisition equipment to perform voltage detection on the water pump and temperature sensor according to the kettle test parameter set. You can also design a software test algorithm to collect data. For example, set the NTC detection function, scan once every 4ms according to the kettle test parameter set, collect the NTC voltage value once every 4ms, and convert it into a digital signal through AD. The software algorithm is designed to collect 20 NTC data per cycle, filter out the maximum and minimum values, and calculate the average value of the remaining 18 data as the output value of a collection cycle. The total time for one cycle is 80ms. The scanning cycle of the water pump detection function is set to scan once every 4ms, and the water pump voltage value Vpump is collected every 4ms and converted into a digital signal through AD. The software algorithm is designed to collect 10 water pump voltage value data per cycle, filter out the maximum and minimum values, and take the average of the remaining 8 data as the output value of a collection cycle. The total time for one cycle is 40ms.

[0031] After that, additional manual intervention is added to collect sensor voltage detection data and water pump voltage detection data by lifting the kettle during the water extraction process. It should be noted that the sensor voltage detection data and water pump voltage detection data here include the voltage changes during the normal water extraction process and the kettle lifting process. According to the sensor voltage detection data and the water pump voltage detection data, the waterproof control time threshold corresponding to the tea bar machine is determined.

[0032] In this process, multiple tests can be performed, for example, after starting the water pump, the kettle lifting operation can be performed multiple times to obtain the sensor voltage detection data and the water pump voltage detection data corresponding to the multiple kettle lifting operations during one water extraction process; the water pump can also be started multiple times, and the manual kettle lifting operation can be performed after each start of the water pump. The test results of multiple tests are averaged and used as the waterproof control time threshold. Since the smaller the setting of the waterproof control time threshold is, the more conducive it is to waterproof control, the waterproof control time threshold can also be determined by the minimum value of multiple test results.

[0033] During the test, the voltage of the water pump and temperature sensor is accurately collected through external probes to ensure the accuracy of the data. The direct measurement method reduces the loss and interference in the signal transmission process and improves the reliability of the data. Through multiple tests, more data samples can be collected to reduce the impact of accidental errors. Averaging or taking the minimum value of the data from multiple tests can further improve the accuracy and stability of the results. The waterproof control time threshold determined according to the test data is more in line with the actual working conditions of the tea bar machine. When the kettle is lifted, the water pump is shut down in time to prevent water overflow or leakage, thereby improving the waterproof performance of the tea bar machine. By optimizing the test parameters and data processing methods, the test time can be shortened and the response speed of the waterproof control can be improved. The accurate waterproof control time threshold helps prevent water damage and extend the service life of the tea bar machine. By optimizing the waterproof control performance, the maintenance and replacement costs caused by water damage can be reduced, and users do not have to worry about water overflow or leakage during use.

[0034] Based on the sensor specification data, a set of kettle test parameters is determined, specifically including: determining the sensor voltage acquisition parameters corresponding to the temperature sensor according to the sensor acquisition accuracy in the sensor specification data, wherein the sensor voltage acquisition parameters include the minimum voltage acquisition period and the sensor voltage acquisition quantity corresponding to the temperature sensor voltage; determining the minimum voltage acquisition period corresponding to the water pump voltage according to the minimum voltage acquisition period corresponding to the temperature sensor voltage, and determining the water pump voltage acquisition quantity based on the sensor voltage acquisition quantity, wherein the water pump voltage acquisition quantity is less than the sensor voltage acquisition quantity.

[0035] In one embodiment of the present specification, during the test of the tea bar machine, it is necessary to determine the voltage acquisition parameters of the temperature sensor. At the same time, since the test item is the maximum allowable time from the temperature sensor disconnection to the water pump shutdown, the voltage detection of the water pump is correlated with the voltage detection of the temperature sensor, so it is also necessary to reasonably set the acquisition parameters of the water pump voltage. The following is an example of determining the collection of test parameters of the kettle in the way of designing the software test algorithm collection: First, obtain the acquisition accuracy information in the temperature sensor specification data, which usually includes key parameters such as the resolution and response time of the temperature sensor. These parameters will directly affect the accuracy and real-time performance of the voltage acquisition. According to the acquisition accuracy and response time of the temperature sensor, determine the minimum acquisition cycle of the temperature sensor voltage, and set the number of sensor voltage acquisitions. For example, the minimum acquisition cycle is 4ms, and the number of sensor voltage acquisitions can be set to 20, that is, collect the NTC voltage value every 4ms, collect a total of 20 NTC voltage data, filter out the maximum and minimum values, and calculate the average value of the remaining 18 data as the output value of a collection cycle. The total time of a cycle is 80ms.

[0036] Since the voltage detection of the water pump is correlated with the voltage detection of the temperature sensor, the minimum collection period of the water pump voltage can be set according to the minimum collection period of the temperature sensor voltage. The number of water pump voltage collections is set based on the number of sensor voltage collections, combined with the changing characteristics of the water pump voltage and the test requirements. Since the change of the water pump voltage is relatively stable, the number of water pump voltage collections can be less than the number of temperature sensor collections, and can be set to half of the number of NTC sensor voltage collections. For example, the minimum collection period of the water pump voltage is 4ms, and the water pump voltage value is collected once every 4ms. A total of 10 water pump voltage values ​​are collected, and the maximum and minimum values ​​are filtered out of the data. The remaining 8 data are averaged as the output value of a collection period. The total time for one cycle is 40ms.

[0037] The sensor voltage detection data and the water pump voltage detection data are analyzed to determine the waterproof control time threshold corresponding to the tea bar machine, specifically including: determining the sensor disconnection detection time through the sensor voltage detection data; determining the water pump stop time according to the water pump voltage detection data; determining the waterproof control time threshold corresponding to the tea bar machine based on the sensor disconnection detection time and the water pump stop time.

[0038] In one embodiment of the present specification, the sensor voltage detection data and the water pump voltage detection data are analyzed to determine the threshold value of the waterproof control time corresponding to the tea bar machine. The sensor voltage detection data is the continuous voltage output generated by the temperature sensor when the device is powered on, the water extraction operation, and the kettle lifting operation. The sensor voltage detection data is analyzed to identify the moment when the voltage suddenly drops, at which time the sensor has been disconnected. This time point is marked as the sensor disconnection detection time. The water pump voltage detection data is analyzed to find the moment when the voltage drops below a certain threshold and lasts for a period of time (indicating that the water pump has stopped working), and this time point is marked as the water pump stop operation time. The time difference between the sensor disconnection detection time and the water pump stop operation time is calculated. The time difference reflects the time from the sensor failure to the water pump response stop, and the corresponding waterproof control time in the current test is determined. According to the above method, the waterproof control time corresponding to multiple test processes is obtained, and the threshold value of the waterproof control time corresponding to the tea bar machine is determined by taking the average value or the minimum value.

[0039] By analyzing the sensor voltage detection data, the moment when the voltage suddenly drops, that is, the time when the sensor is disconnected, can be accurately identified, ensuring the accuracy of the disconnection time; by analyzing the water pump voltage detection data, the time when the water pump stops running can be determined, thereby evaluating the response speed of the water pump to the sensor disconnection; by determining a reasonable waterproof control time threshold, the water pump can be shut down in time when the sensor is disconnected, effectively preventing damage caused by water leakage.

[0040] When determining the current voltage detection cycle corresponding to the temperature sensor through the waterproof control time threshold, it can be implemented in two ways, and the following are two corresponding embodiments:

[0041] Embodiment 1: Determining the current voltage detection cycle corresponding to the temperature sensor through the waterproof control time threshold, specifically comprising: determining the current voltage detection cycle corresponding to the temperature sensor according to the product of the waterproof control time threshold and a preset margin ratio.

[0042] In one embodiment of the present specification, after determining the waterproof control time threshold, a safety margin is set based on the waterproof control time threshold. First, the margin ratio is pre-set, for example, it can be set to 80%. The setting of the margin ratio can be based on empirical data. The smaller the margin ratio is set, the larger the reserved safety margin is. For example, when the margin ratio is set to 80%, the corresponding safety margin is 20%. The current voltage detection period corresponding to the temperature sensor is determined by multiplying the waterproof control time threshold and the margin ratio. For example, if the waterproof control time threshold of the temperature sensor of the tea bar machine is 20ms, the corresponding current voltage detection period is 20ms*80%, which is 16ms; if the waterproof control time threshold of the temperature sensor of the tea bar machine is 30ms, the corresponding current voltage detection period is 30ms*80%, which is 24ms.

[0043] After determining the waterproof control time threshold, the method of further setting a safety margin on this basis brings many beneficial effects to the voltage detection cycle setting of the tea bar machine temperature sensor; by setting the safety margin, it can be ensured that on the basis of the waterproof control time threshold, additional time is reserved for possible unexpected situations (such as voltage fluctuations, sensor response delays, etc.), which helps to prevent safety hazards caused by insufficient time, thereby improving overall safety; the setting of the safety margin helps to reduce the impact of environmental factors or internal changes on the voltage detection cycle, ensures that the tea bar machine can operate more stably, helps to maintain the accuracy and reliability of the tea bar machine temperature sensor, and thus ensures the overall performance of the tea bar machine; through reasonable voltage detection cycle settings, the waterproof control effect of the tea bar machine can be improved.

[0044] Embodiment 2: Determine the current voltage detection period corresponding to the temperature sensor through the waterproof control time threshold, specifically including: obtaining the theoretical voltage detection parameter of the temperature sensor, wherein the theoretical voltage detection parameter includes the theoretical collection period of each voltage data; determine the standard control time parameter corresponding to the temperature sensor through the waterproof control time threshold and a pre-set margin ratio; based on the theoretical voltage detection parameter, correct the standard control time parameter to determine the current voltage detection period corresponding to the temperature sensor.

[0045] In one embodiment of the present specification, when the current voltage detection period corresponding to the temperature sensor is determined by the waterproof control time threshold, the theoretical voltage detection parameter of the temperature sensor is obtained. It should be noted that the theoretical voltage detection parameter includes the theoretical acquisition period of each voltage data. The theoretical acquisition period here can be determined by the specification parameters of the temperature sensor and can be directly set to the minimum acquisition period of the test phase, such as 4ms. After determining the theoretical voltage detection parameter, the standard control time parameter corresponding to the temperature sensor is determined by the waterproof control time threshold and the pre-set margin ratio. The setting of the margin ratio here is the same as the margin ratio setting in the above-mentioned embodiment 1. The standard control time parameter corresponding to the temperature sensor is determined by multiplying the waterproof control time threshold and the margin ratio. Using the theoretical voltage detection parameter, the standard control time parameter is corrected to determine the current voltage detection period corresponding to the temperature sensor.

[0046] Based on the theoretical voltage detection parameter, the standard control time parameter is corrected to determine the current voltage detection period corresponding to the temperature sensor, specifically including: dividing the standard control time parameter and the theoretical voltage detection parameter to determine the remainder between the standard control time parameter and the theoretical voltage detection parameter; when the remainder is non-zero, determining the current voltage detection period corresponding to the temperature sensor based on the difference between the standard control time parameter and the remainder.

[0047] In one embodiment of the present specification, a division operation is performed on the standard control time parameter and the theoretical voltage detection parameter, and the standard time parameter is divided by the theoretical voltage detection parameter to obtain the remainder between the standard control time parameter and the theoretical voltage detection parameter. For example, assuming that the standard control time parameter is 16ms and the theoretical voltage detection parameter is 5ms, the remainder of 16 / 5 is 1. After obtaining the remainder between the standard control time parameter and the theoretical voltage detection parameter, the remainder is subtracted from the standard control time parameter to obtain the current voltage detection period corresponding to the temperature sensor. The current voltage detection period obtained in the above manner ensures that the current voltage detection period is an integer multiple of the theoretical voltage detection parameter, and complete sensor voltage data can be collected, and also ensures that the current voltage detection period is less than the standard control time parameter to meet the reserved safety margin.

[0048] Step S102, under the triggering of the water pump water intake operation of the tea bar machine, the voltage value of the temperature sensor is collected according to the current voltage detection cycle to determine multiple sensor voltage data.

[0049] In one embodiment of the present specification, under the triggering of the water pump water extraction operation of the tea bar machine, the sensor detection cycle is set according to the current voltage detection cycle, and detection is performed once per theoretical voltage detection parameter within the sensor detection cycle. That is to say, multiple sensor voltage values ​​can be collected within the sensor detection cycle. Assume that the theoretical voltage detection parameter is 5ms, and the current voltage detection cycle is 15ms, that is, a sensor voltage data is detected every 5ms, and a total of 3 data are detected within 15ms, and the 3 detected data are all sensor voltage data.

[0050] Step S103, based on the voltage data of multiple sensors, the tea bar machine is subjected to a kettle lifting operation detection, and when the kettle lifting operation is detected, the water pump is controlled to be turned off.

[0051] In one embodiment of the present specification, since the sensor voltage of the temperature sensor will change accordingly when the user lifts the kettle, the tea bar machine can be detected for lifting the kettle based on multiple sensor voltage data. When the lifting kettle operation is detected, a shutdown instruction is sent to the water pump according to a preset control logic.

[0052] Based on the multiple sensor voltage data, the tea bar machine is subjected to a kettle lifting operation detection, specifically comprising: obtaining the disconnection reference voltage data corresponding to the temperature sensor when the kettle is lifted; and performing a kettle lifting operation detection on the tea bar machine according to the multiple sensor voltage data and the disconnection reference voltage data.

[0053] In one embodiment of the present specification, the disconnection reference voltage data corresponding to the temperature sensor when the kettle is lifted is obtained. It should be noted that the disconnection reference voltage data here can obtain the corresponding reference value during the whole machine test. Generally, the disconnection voltage of the NTC sensor is 5V. The kettle lifting operation detection is performed on the tea bar machine through the relationship between the multiple sensor voltage data corresponding to the temperature sensor collected in the current voltage detection cycle and the disconnection reference voltage data.

[0054] In one embodiment of the present specification, when performing the kettle lifting detection by comparing the magnitude relationship between multiple sensor voltage data and disconnection reference voltage data, multiple determination methods can be used. For example, if a specified number of sensor voltage data are not less than the reference voltage data in a row, it is determined that the kettle lifting operation is detected. For another example, if more than half of the data collected in the current voltage detection cycle are not less than the reference voltage data, it is determined that the kettle lifting operation is detected.

[0055] According to the multiple sensor voltage data and the disconnection reference voltage data, the tea bar machine is subjected to a kettle lifting operation detection, specifically comprising: determining the average voltage data of the multiple sensor voltage data; when the average voltage data is not less than the disconnection reference voltage data, determining that the kettle lifting operation is detected.

[0056] In one embodiment of the present specification, the average voltage data of multiple sensor voltage data can also be calculated to determine the relationship between the average voltage data and the disconnection reference voltage data. When the average voltage data is not less than the disconnection reference voltage data, it is determined that the kettle lifting operation is detected.

[0057] Through comprehensive judgment of multiple sensor voltage data, the detection accuracy of the kettle lifting operation can be improved and the possibility of misjudgment can be reduced; the disconnection reference voltage data is used as the judgment basis. This data can be obtained through whole machine testing, ensuring the matching with the actual use environment. At the same time, by comparing the size relationship between multiple sensor voltage data and the disconnection reference voltage data, it can be more flexibly adapted to the kettle lifting operation detection in different situations; when the kettle lifting operation is detected, a shutdown command is immediately sent to the water pump to avoid water overflow caused by the continued operation of the water pump.

[0058] Through the above technical scheme, firstly, by determining the current voltage detection cycle corresponding to the temperature sensor of the tea bar machine, the current voltage detection cycle is determined on the basis of considering the control time between disconnecting the sensor and stopping the water pump in the tea bar machine, thereby ensuring that the setting of the current voltage detection cycle meets the waterproof control time corresponding to the tea bar machine; by continuously collecting multiple temperature sensor voltage data corresponding to the temperature sensor within the current voltage detection cycle, through the comprehensive judgment of multiple sensor voltage data, the kettle lifting operation can be discovered in time, the detection time of the kettle lifting operation is shortened, and the detection accuracy of the kettle lifting operation can be improved, and the possibility of misjudgment is reduced; when the kettle lifting operation is detected, the water pump is immediately controlled to be turned off, thereby avoiding a small amount of water from being sprayed into the coupler due to lifting the kettle during the operation of the water pump, effectively preventing the risk of short-circuit failure of electronic components such as NTC in the coupler due to contact with moisture, and by collecting voltage data in real time within the current voltage detection cycle, the voltage data is used to accurately detect the kettle lifting operation and immediately turn off the water pump, effectively avoiding a small amount of water from being sprayed into the coupler due to lifting the kettle.
