Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may mean A or B. The "and / or" in the text is only a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] To improve the usage efficiency and safety of the water treatment device, an embodiment of the present application provides a flow control method, and the execution subject of the flow control method is the water treatment device. The following is a detailed description. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments. Please refer to Figure 1 , Figure 1 It is a controller architecture diagram of a flow control method provided by an embodiment of the present application. The specific process of the flow control method can be as follows:

[0029] Figure 1It is a schematic diagram of the scenario of a flow control method provided by an embodiment of the present application.

[0030] As Figure 1 shown, the water treatment device includes a solenoid valve, a negative pressure valve, a flow meter, a capacitance sensor, a water pump, and an instant heating unit. Among them, the solenoid valve is used to control the opening and closing of the water flow. It controls the opening and closing of the valve through an electromagnetic signal to ensure that water flows into the water treatment device only when needed. The negative pressure valve is used to prevent negative pressure from being generated inside the water treatment device to ensure smooth water flow. The negative pressure valve will automatically open when the internal pressure of the water treatment device is too low to prevent water backflow or the formation of a vacuum inside the controller. The flow meter is used to measure the incoming water flow and can provide real-time flow data for monitoring and controlling the water flow. The capacitance sensor is used to detect the characteristics of water, such as water quality, temperature, or other parameters. The water pump is used to provide power to pump water from the water inlet to the instant heating unit. The instant heating unit is used to heat the water delivered by the water pump to the temperature required by the user.

[0031] Specifically, when the water treatment device is operating, water flows in from the water inlet. At this time, the solenoid valve receives an opening signal to allow water to flow in, and at the same time, the negative pressure valve ensures that no negative pressure is generated inside the water treatment device to prevent pipeline deformation or rupture. The flow meter collects the water flow at the water inlet every preset time interval within a preset unit time and sends the water flow within the preset unit time to the controller of the water treatment device. The controller compares the obtained water flow with a preset flow threshold to determine the water usage load level of the water treatment device. Among them, the water usage load level is divided into an intervention load level and a safety load level. When the water treatment device is at the safety load level, it means that the user's water demand is small, and the water flow provided by the water inlet can meet the user's actual water demand, that is, the incoming water flow is greater than the user's water consumption. In this scenario, there is no need to adjust the operating voltage of the water pump.

[0032] When the water usage load level of the water treatment device is the intervention load level, it indicates that the user's water demand is relatively large, and the water flow rate entering from the water inlet cannot fully meet the user's actual water demand, that is, the inlet water flow rate is less than the user's water consumption. In this scenario, the inlet water temperature at the water inlet is further obtained in real time through the built-in water temperature sensor. By comparing the inlet water temperature with the preset inlet water temperature threshold, when the inlet water temperature is lower than the inlet water temperature threshold, the controller of the water treatment device determines that a longer heating time is required to reach the hot water temperature required by the user. Therefore, the operating voltage of the water pump is reduced to reduce its output power, thereby slowing down the water flow rate and ensuring that the water has sufficient residence time in the instant heating unit for sufficient heating. This can not only ensure that the water temperature meets the user's needs, but also automatically reduce the operating voltage of the water pump to reduce unnecessary energy consumption and mechanical wear to achieve energy-saving effects, while avoiding problems such as uneven heating or unstable controller caused by too fast water flow, improving the efficiency, stability and safety of the entire water supply controller.

[0033] Exemplarily, when the user turns on the water treatment device, water enters from the water inlet at this time. The solenoid valve receives the operation signal of the water treatment device and allows the water flow to pass through. The negative pressure valve ensures that there is no negative pressure in the system. The flow meter measures the inlet water flow rate every 5 seconds and sends it to the controller. Suppose that within 1 minute, the inlet water flow rate recorded by the flow meter is 30 liters, while the preset safe flow threshold is 40 liters. The controller finds that the current water flow rate is lower than the preset safe threshold and determines it as the intervention load level. At this time, the built-in water temperature sensor shows that the inlet water temperature is 10 degrees Celsius, which is lower than the set threshold of 15 degrees Celsius. In order to ensure that the user can obtain hot water with sufficient temperature, the controller decides to reduce the operating voltage of the water pump from 220 volts to 180 volts, slow down the water flow rate, so that the water has more time to be heated in the instant heating unit, while reducing the energy consumption and wear of the water pump, and improving the use efficiency and safety of the water treatment device.

[0034] Based on Figure 1 the scene diagram shown below, the following will be combined with Figures 2 - 7 to introduce in detail a flow control method provided by an embodiment of the present application.

[0035] Based on the above situation, an embodiment of the present application proposes a flow control method. Please refer to Figure 2 , Figure 2 which is a schematic flow chart of a flow control method provided by an embodiment of the present application. As Figure 2 shown, the method of the embodiment of the present application may include the following steps S101 - step S103.

[0036] S101, obtain the inlet water flow rate at the water inlet of the water treatment device within a preset time period.

[0037] In the embodiments of the present application, the flowmeter is usually installed on the pipeline at the water inlet of the water treatment equipment. Common flowmeters include electromagnetic flowmeters, turbine flowmeters, vortex street flowmeters, etc., and no specific limitations are imposed here. Taking the electromagnetic flowmeter as an example, based on Faraday's law of electromagnetic induction, when a conductive liquid flows in a magnetic field, an induced electromotive force will be generated in the direction perpendicular to both the magnetic field direction and the liquid flow direction, and this electromotive force is proportional to the flow velocity of the liquid.

[0038] The flowmeter itself is equipped with a signal output device for transmitting the measured flow signal (usually an analog signal or a digital signal) to the connected data acquisition unit. Among them, the data acquisition unit can be a module on the control main board of the water treatment equipment or a dedicated external data collector. For analog signals, the data acquisition unit will convert them into digital signals through an analog-to-digital conversion (ADC) circuit for subsequent processing and storage.

[0039] Specifically, the inlet water timer is enabled when the water treatment equipment is in an operating state. Within a preset duration, the data acquisition unit will collect the flow data transmitted by the flowmeter at a certain frequency (for example, once per second) and store these data in a preset storage area. When the preset duration ends, the data acquisition unit will process the stored flow data. If the flow data is instantaneous flow, it is necessary to calculate the cumulative flow within the preset duration and record it as the inlet water flow within the preset duration. For a stable flow, the cumulative flow can be simply obtained by multiplying the instantaneous flow by the preset duration to get the inlet water flow within the preset duration. However, if the flow is fluctuating, it is necessary to perform integral calculation on the flow data at each time point to determine the inlet water flow within the preset duration.

[0040] S102. Compare the inlet water flow with a preset flow threshold to determine the water usage load level of the water treatment equipment.

[0041] Specifically, the water treatment equipment obtains the inlet water flow data through the flowmeter installed on the inlet pipeline. This flowmeter can measure and transmit the flow velocity information of the water flow at the inlet in real time, and the data acquisition unit will process the signal transmitted by the flowmeter and convert it into a directly readable inlet water flow value.

[0042] When the data acquisition unit receives the current inlet water flow data, it starts to perform a comparison operation with the preset flow threshold. Three flow thresholds are preset in the water treatment equipment, namely the first flow threshold, the second flow threshold, and the third flow threshold, and the first flow threshold is greater than the second flow threshold which is greater than the third flow threshold.

[0043] If the detected water inlet flow rate is equal to or greater than the first flow threshold, it indicates that the water inlet condition of the current water treatment device is in an ideal state, with sufficient water volume and within the range that the water treatment device can handle efficiently and safely. At this time, the water usage load level of the water treatment device is determined to be the safe load level. Under the safe load level, the operating voltage of the water pump of the water treatment device does not require additional intervention or adjustment and can continuously and stably treat the inlet water to meet the expected water quality standards.

[0044] If the water inlet flow rate is equal to or greater than the second flow threshold but less than the first flow threshold, it means that although the water inlet flow rate has not reached the optimal state, it is still at an acceptable relatively high level. However, it has begun to approach the range that can affect the treatment effect or operating stability of the water treatment device. At this time, the water usage load level of the water treatment device is determined to be the first intervention load level. If the water inlet flow rate is equal to or greater than the third flow threshold and less than the second flow threshold, the water usage load level of the water treatment device is determined to be the second intervention load level. Under the second intervention load level, through the process of comparing the water inlet flow rate with the preset flow threshold, the water treatment device can accurately determine its own water usage load level and implement corresponding coping strategies according to different levels, so as to ensure that the device can operate as efficiently and stably as possible under different water inlet flow rate conditions.

[0045] S103. If the water usage load level is the intervention load level, obtain the water inlet temperature of the water treatment device and determine the operating voltage of the water pump based on the water inlet temperature.

[0046] Specifically, when the water usage load level is determined to be the first intervention load level, the controller of the water treatment device immediately obtains the current initial operating voltage of the water pump. This initial operating voltage can be obtained by a voltage sensor connected to the water pump or read from the operating parameter record of the water pump. At the same time, the temperature sensor in the water treatment device measures the water inlet temperature, obtains the current water inlet temperature value, and compares it with the preset water temperature threshold. If the water inlet temperature is less than the water temperature threshold, it indicates that under the current first intervention load level, the water inlet temperature is low, which will affect the overall heating process. Then, the controller adjusts the initial operating voltage of the water pump to the first target operating voltage according to the preset adjustment strategy. The first target operating voltage is a voltage value obtained through experiments or theoretical calculations and is suitable for this low-temperature and first intervention load level working condition to enable the water pump to operate efficiently and stably, so as to ensure that under this load level and water inlet temperature condition, the water pump can operate at an appropriate power to maintain the normal circulation and treatment process of the water flow inside the water treatment device.

[0047] When it is determined that the water usage load level is the second intervention load level, first obtain the initial operating voltage of the water pump. Then, judge the inlet water temperature. If the inlet water temperature is equal to or higher than the water temperature threshold, it means that although it is at the second intervention load level, the inlet water temperature is relatively high. At this time, adjust the initial operating voltage to the first target operating voltage to optimize the operating parameters of the water pump under this working condition and ensure that the equipment can operate effectively at this load level and higher inlet water temperature. If the inlet water temperature is lower than the water temperature threshold when the water usage load level is the second intervention load level, then adjust the initial operating voltage to the second target operating voltage. This second target operating voltage is specifically set for this low-temperature and second intervention load level situation. Different from the first target operating voltage, the second target operating voltage can better adapt to this more challenging operating condition, enabling the water pump to still maintain a certain operating performance in a low-load and low-temperature environment, minimizing the impact on the entire water treatment process, and ensuring that the water treatment equipment can operate as stably as possible under different load levels and combinations of inlet water temperatures, achieving effective control and optimization of the water treatment process.

[0048] As can be seen from the above, by obtaining the inlet water flow rate at the water treatment equipment inlet within a preset time period and comparing it with a preset flow rate threshold, the water usage load level of the water treatment equipment can be accurately determined. This not only helps to promptly detect and respond to potential changes in water usage demand but also effectively avoids problems such as water pump overload or underload caused by abnormal flow rates, thereby significantly improving the safety of water pump use. If the water usage load level is determined to be the intervention load level, further obtain the inlet water temperature and precisely adjust the operating voltage of the water pump based on this temperature. Adopting this solution can ensure that the water flow obtains an appropriate heating time in the instant heating unit, meeting the user's demand for hot water temperature while avoiding energy waste caused by insufficient or excessive heating. By dynamically adjusting the water pump voltage, unnecessary mechanical wear can also be reduced, extending the service life of the water pump.

[0049] In the actual scenario, since the actual water usage data of users will show dynamic changes, it is necessary to adjust the operating voltage of the water pump in real time according to the actual water usage data of users. Please refer to Figure 3 , Figure 3 which is a schematic flow diagram of a flow control method provided by an embodiment of the present application. As Figure 3 shown, the method of the embodiment of the present application may include the following steps S201 - S204.

[0050] S201, if the inlet water flow rate is equal to or greater than a preset first flow rate threshold, determine that the water usage load level of the water treatment equipment is the safe load level.

[0051] In the embodiment of the present application, if it is detected that the influent flow rate is equal to or greater than the first flow rate threshold, this indicates that the influent situation of the current water treatment device is in an ideal state, with sufficient water volume and within the range that the water treatment device can efficiently and safely handle. At this time, the water usage load level of the water treatment device is determined to be the safe load level. Under the safe load level, the operating voltage of the water pump of the water treatment device does not require additional intervention or adjustment and can continuously and stably treat the influent to meet the expected water quality standards.

[0052] Exemplarily, the first flow rate threshold is 800 milliliters per minute, and when the water treatment device is operating, the flowmeter continuously monitors the water flow situation at the influent port. When it is detected that the influent flow rate reaches 900 milliliters per minute in a certain monitoring, since 900 milliliters per minute is greater than the preset first flow rate threshold of 800 milliliters per minute, according to the established rule, the water treatment device determines that its current water usage load level is the safe load level at this time. This means that the current water volume entering the device is sufficient and within the ideal range that the device can efficiently handle, and there is no need to adjust or intervene in the operating voltage of the water pump.

[0053] S202, if the influent flow rate is equal to or greater than the preset second flow rate threshold and less than the first flow rate threshold, then determine that the water usage load level of the water treatment device is the first intervention load level.

[0054] In the embodiment of the present application, if the influent flow rate is equal to or greater than the second flow rate threshold but less than the first flow rate threshold, it means that although the influent flow rate has not reached the best state, it is still at an acceptable relatively high level, but it has begun to approach the range that may affect the treatment effect or operating stability of the device. At this time, determine that the water usage load level of the water treatment device is the first intervention load level, where the second flow rate threshold can be set according to the actual usage scenario and is not specifically limited here.

[0055] Exemplarily, the second flow rate threshold is 600 milliliters per minute. When the influent flow rate at the influent port is monitored to be 700 milliliters per minute, since it is greater than the preset second flow rate threshold of 600 milliliters per minute and less than the first flow rate threshold of 800 milliliters per minute, the water usage load level of the water treatment device is determined to be the first intervention load level at this time.

[0056] S203, if the influent flow rate is equal to or greater than the preset third flow rate threshold and less than the second flow rate threshold, then determine that the water usage load level of the water treatment device is the second intervention load level.

[0057] In the embodiment of the present application, if the influent flow rate is equal to or greater than the third flow rate threshold and less than the second flow rate threshold, at this time determine that the water usage load level of the water treatment device is the second intervention load level, where the third flow rate threshold can be set according to the actual usage scenario and is not specifically limited here.

[0058] Exemplarily, the third flow rate threshold is 400 milliliters per minute. The flow meter detects that the water inlet flow rate at the water inlet is 500 milliliters per minute within a preset duration. Since it is greater than the third flow rate threshold of 400 milliliters per minute and less than the second flow rate threshold of 600 milliliters per minute, the water usage load level of the water treatment device is determined to be the second intervention load level.

[0059] S204, if the water inlet flow rate is less than the third flow rate threshold, generate a load prompt message and control the water pump to operate at the minimum operating voltage.

[0060] Specifically, the flow meter in the water treatment device accurately measures the flow rate of the water inlet in real time and transmits the measurement data to the controller of the water treatment device. When the controller receives water inlet flow rate data less than the preset third flow rate threshold, it immediately triggers the load prompt message generation mechanism. At this time, the controller constructs a complete load prompt message according to a pre-set information template, including key information such as device number, abnormal water inlet flow rate value, time stamp, etc. Then, through a built-in communication module, such as a communication module based on Wi-Fi, Bluetooth or cellular network, the load prompt message is sent to a mobile device associated with the water treatment device.

[0061] At the same time, the controller sends an instruction to the drive circuit of the water pump, requiring the operating voltage of the water pump to be adjusted to the minimum operating voltage. This instruction is transmitted to the voltage regulating device of the water pump through an electrical control circuit, and the device gradually reduces the voltage according to the instruction until the minimum operating voltage set value is reached. During the adjustment process, the change of the voltage will be continuously monitored to ensure the accuracy and stability of the adjustment.

[0062] Exemplarily, after the controller receives the water inlet flow rate data sent by the flow meter and finds that the water inlet flow rate is lower than the third flow rate threshold, the controller quickly generates a corresponding load prompt message, for example, "The water usage load exceeds the load threshold, please pay attention", and sends the load prompt message to the user's mobile phone APP or broadcasts it through a smart device.

[0063] Please refer to Figure 4 , Figure 4 which is a schematic diagram of the scenario of a flow control method provided by an embodiment of the present application. As Figure 4As shown: Starting from obtaining the influent flow rate, first compare the influent flow rate with the first flow rate threshold. If the influent flow rate is greater than or equal to the first flow rate threshold, the water treatment device is at the safe load level; if it is less than the first flow rate threshold, continue to compare it with the second flow rate threshold. If the influent flow rate is greater than or equal to the second flow rate threshold and less than the first flow rate threshold, it is at the first intervention load level; if it is less than the second flow rate threshold, then compare it with the third flow rate threshold. If the influent flow rate is greater than or equal to the third flow rate threshold and less than the second flow rate threshold, it is at the second intervention load level; if it is less than the third flow rate threshold, generate a load prompt message.

[0064] As can be seen from the above, when the influent flow rate reaches or exceeds the first flow rate threshold, the water treatment device is at the safe load level and can operate stably and efficiently. Secondly, for the cases of the first intervention load level and the second intervention load level, the water treatment device can take corresponding optimization intervention measures according to different load levels to ensure that the treatment effect still meets the standards when there are certain fluctuations in the influent flow rate. Finally, when the influent flow rate is less than the third flow rate threshold, generating a load prompt message can timely notify personnel to check and solve problems. At the same time, controlling the water pump to work at the minimum operating voltage can prevent the water pump from being damaged, while ensuring the basic operating state of the water treatment device and prolonging the service life of the water treatment device.

[0065] Since there will be additional power overflow when the influent flow rate is small and the operating voltage of the water pump is high, and when the influent water temperature is low, if the water pump power is large, it will cause the water flow to be too fast, resulting in the water temperature not being heated to the temperature required by the user. Therefore, it is necessary to control the operating voltage of the water pump according to the influent flow rate and the influent water temperature. Please refer to Figure 5 , Figure 5 is a flowchart of a flow control method provided by an embodiment of the present application. As Figure 5 shown, the method of the embodiment of the present application may include the following steps S301 - S305.

[0066] S301, determine the water use load level of the water treatment device.

[0067] Specifically, for the execution process of S301, please refer to the above S102 and will not be elaborated here.

[0068] S302, if the water use load level is the first intervention load level, obtain the initial operating voltage of the water pump.

[0069] Specifically, when the water use load level of the water treatment device is determined to be the first intervention load level (that is, the influent flow rate is equal to or greater than the preset second flow rate threshold and less than the first flow rate threshold), the controller obtains the current operating voltage of the water pump and defines it as the initial operating voltage.

[0070] Exemplarily, when the water usage load level of the water treatment device is the first intervention load level, the current operating voltage of the water pump is obtained as 200V, and at this time, 200V is determined as the initial operating voltage of the water pump.

[0071] S303. If the inlet water temperature is less than the water temperature threshold, then adjust the initial operating voltage to the first target operating voltage.

[0072] In the embodiment of the present application, the water temperature threshold can be set according to the actual application scenario, and no specific limitation is made here.

[0073] Specifically, under the first intervention load level, obtain the inlet water temperature at the water inlet of the water treatment device according to the preset water temperature sensor, and compare it with the preset water temperature threshold. If the inlet water temperature is less than the water temperature threshold, then adjust the initial operating voltage of the water pump to the first target operating voltage. Among them, the first target operating voltage can be the voltage obtained after reducing the initial operating voltage by 10%, and the first target operating voltage can also be set according to the actual usage scenario, and no specific limitation is made here.

[0074] Exemplarily, the water treatment device is at the first intervention load level and the water temperature threshold is 15 degrees Celsius, and the inlet water temperature detected by the water temperature sensor is 10 degrees Celsius. At this time, since the inlet water temperature is less than the water temperature threshold, the initial operating voltage is decreased by 10% to obtain the first target operating voltage. For example, if the initial operating voltage is 220V, then the first target operating voltage is 198V, and control the water pump to operate at 198V.

[0075] S304. If the water usage load level is the second intervention load level, then adjust the initial operating voltage to the first target operating voltage when the inlet water temperature is equal to or greater than the water temperature threshold.

[0076] In the embodiment of the present application, when the water usage load level is the second intervention load level (that is, the inlet water flow rate is equal to or greater than the preset third flow rate threshold and less than the second flow rate threshold), the inlet water temperature is also obtained based on the preset water temperature sensor. If the inlet water temperature is equal to or greater than the water temperature threshold, then adjust the initial operating voltage of the water pump to the first target operating voltage. Among them, for the execution process of adjusting the initial operating voltage to the first target operating voltage, please refer to the above S303, and details are not described here again.

[0077] S305. When the water usage load level is the second intervention load level, if the inlet water temperature is less than the water temperature threshold, then adjust the initial operating voltage to the second target operating voltage.

[0078] Specifically, at the second intervention load level, the water inlet temperature of the water treatment device is obtained according to a preset water temperature sensor and compared with a preset water temperature threshold. If the water inlet temperature is less than the water temperature threshold, the initial operating voltage of the water pump is adjusted to a second target operating voltage. The second target operating voltage can be the voltage obtained by reducing the initial operating voltage by 15%, and the second target operating voltage can also be set according to the actual usage scenario, which is not specifically limited here.

[0079] Exemplarily, when the water treatment device is at the second intervention load level, the water temperature threshold is 15 degrees Celsius, and the water inlet temperature detected by the water temperature sensor is 10 degrees Celsius. At this time, since the water inlet temperature is less than the water temperature threshold, the initial operating voltage is decreased by 15% to obtain the second target operating voltage. For example, if the initial operating voltage is 220V, the second target operating voltage is 157V, and the water pump is controlled to operate at 187V.

[0080] Please refer to Figure 6 , Figure 6 which is a schematic diagram of the scenario of a flow control method provided by an embodiment of the present application. As Figure 6 shown: First, the inlet water flow is compared with a first flow threshold. If it is greater than or equal to the first flow threshold, it enters the safe load level; if it is less than the first flow threshold, it is compared with a second flow threshold. If it is greater than or equal to the second flow threshold, it enters the first intervention load level, and then further determines whether to apply the first target operating voltage according to the relationship between the inlet water temperature and the water temperature threshold; if it is less than the second flow threshold, it is compared with a third flow threshold. If it is greater than or equal to the third flow threshold, it enters the second intervention load level, and further determines whether to apply the first target operating voltage or the second target operating voltage according to the relationship between the inlet water temperature and the water temperature threshold; if it is less than the third flow threshold, a load prompt message is generated. The entire flowchart determines the load level and operating voltage of the water treatment device by judging the inlet water flow and temperature.

[0081] As can be seen from the above, for the first intervention load level, adjusting the voltage of the water pump according to the inlet water temperature can enable the water pump to adapt to temperature changes, optimize the operating efficiency and reduce energy consumption when the inlet water temperature is low. For the second intervention load level, adjusting the voltage of the water pump according to the inlet water temperature can maintain the stability of the device and prevent overheating failures when the inlet water temperature is high; when the inlet water temperature is low, it can make the water pump operate at an appropriate power, protect the device, save energy, and improve the reliability of the operation of the water treatment device.

[0082] Since in the actual scenario, the actual water usage data of users will show dynamic changes, it is necessary to adjust the operating voltage of the water pump in real time according to the actual water usage data of users. As Figure 7 shown, the method of the embodiment of the present application may include the following step S401.

[0083] S401. When the water pump is operating at the first target operating voltage or the second target operating voltage, if it is detected that the water usage load level has returned to the safe load level, control the water pump to operate at the initial operating voltage.

[0084] Specifically, when the water pump is operating at the first target operating voltage or the second target operating voltage, continuously monitor the water usage load level. Once it is detected that the water inflow rate reaches or meets the preset flow threshold, that is, when the water usage load level has returned to the safe load level, immediately send a control signal to the voltage regulation module of the water pump. This control signal will instruct the voltage regulation module to adjust the operating voltage of the water pump from the current first target operating voltage or second target operating voltage back to the initial operating voltage.

[0085] During the adjustment process, the voltage regulation module will gradually change the power supply voltage of the water pump according to the requirements of the control signal. For example, if the water pump is restored from the first target operating voltage to the initial operating voltage, the voltage regulation module will increase the power supply voltage to the initial value; if it is restored from the second target operating voltage, it will also accurately adjust to the initial operating voltage.

[0086] As can be seen from the above, through the voltage control and monitoring mechanism, it can be ensured that the water pump can smoothly switch from the low-voltage operating state to the initial operating voltage state, thereby ensuring that the water treatment equipment operates at the best performance under the safe load level, avoiding damage to the water pump caused by voltage mutation, and ensuring the stable operation and service life of the water treatment equipment.

[0087] Based on Figure 1 the scenario schematic diagram, the flow control device provided by the embodiment of the present application will be introduced in detail below.

[0106] In the embodiments of the present application, by obtaining the inlet water flow rate at the water treatment device inlet within a preset time period and comparing it with a preset flow rate threshold, the water usage load level of the water treatment device can be accurately determined. This not only helps to timely detect and respond to potential changes in water usage demand but also effectively avoids problems such as water pump overload or underload caused by abnormal flow rates, thereby significantly improving the usage safety of the water pump. If the water usage load level is determined to be an intervention load level, the inlet water temperature is further obtained, and based on this temperature, the operating voltage of the water pump is precisely adjusted. Adopting this solution can ensure that the water flow obtains an appropriate heating time in the instant heating unit, meeting the user's demand for hot water temperature while avoiding energy waste caused by insufficient or excessive heating. By dynamically adjusting the water pump voltage, unnecessary mechanical wear can also be reduced, extending the service life of the water pump.
