[0025] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the technical solutions in the embodiments of the present application are further described in detail through the following embodiments and in combination with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. It should also be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, rather than all structures.

[0026] Figure 1 A schematic diagram of the structure of the water purification device provided in the embodiment of the present application. Figure 1 As shown, the water purification device includes: a water inlet pipeline 10, a composite filter element 11, a booster pump 12, a reverse osmosis filter element 13 (or reverse osmosis membrane) and a water outlet pipeline 14 connected in series.

[0027] Wherein, a pressure sensor (such as a pressure gauge 15) is provided in the water inlet pipeline 10, and the water inlet pressure of the water purification equipment can be collected through the pressure sensor.

[0028] The composite filter element 11 may include a pre-filter element and a post-filter element. The pre-filter element may be a PP cotton filter element, a carbon rod filter element, etc., which is used to perform primary filtration on the raw water flowing in through the water inlet pipe 10 to produce primary purified water. Users can use this primary purified water to wash fruits, vegetables, tableware, etc. Optionally, the water purification device may be provided with a total dissolved solids (TDS) probe 16 on the pipe between the pre-filter element and the water purification port, and the water quality of the purified water may be detected by the TDS probe 16.

[0029] The purified water after being filtered by the pre-filter is pressed into the reverse osmosis filter element 13 by the booster pump 12, and the reverse osmosis filter element 13 further filters the purified water to generate pure water; the post-filter element further performs post-stage filtration on the pure water, such as a post-carbon rod filter element. Optionally, a TDS probe can also be provided on the pipeline between the reverse osmosis filter element 13 and the post-filter element of the water purification equipment, and the water quality of the pure water can be detected by the TDS probe. Optionally, the above-mentioned TDS probe can be integrated with a temperature sensor.

[0030] A faucet can be installed at the end of the water outlet pipe 14. The faucet can be a combined clean water / pure water outlet faucet, or it can be two faucets that each outlet water, namely a clean water outlet faucet and a pure water outlet faucet. This embodiment of the present application does not limit this.

[0031] The reverse osmosis filter element 13 may be provided with a wastewater solenoid valve, and the concentrated water filtered by the reverse osmosis filter element is discharged from the water purification equipment through the wastewater solenoid valve and the wastewater pipeline.

[0032] The above water purification equipment provides a quantitative water extraction function, which can automatically stop the water supply after the water extraction is completed. During the water extraction process, the user does not need to wait for the water extraction to end, which is very convenient. The control logic of the quantitative water extraction function of the above water purification equipment is as follows:

[0033] Figure 2 A flow chart of a control method for a water purification device provided in an embodiment of the present application. Figure 2 As shown, the method may include:

[0034] S201. In response to a user's quantitative water extraction instruction, determine a current water outlet speed correction parameter of a water purification device.

[0035] In actual use, the actual water output speed of the water purification equipment is not constant, that is, the actual water output speed of the water purification equipment is not necessarily completely equivalent to the nominal theoretical water output speed. It will be affected by many factors, such as the inlet water temperature, the state of the reverse osmosis filter element and the inlet water pressure, etc. Therefore, when receiving the user's quantitative water extraction instruction, it is also necessary to determine the current water output speed correction parameter of the water purification equipment in combination with the operating status of the water purification equipment, and use the water output speed correction parameter to correct the theoretical water output speed of the water purification equipment.

[0036] Among them, the theoretical water output rate refers to the nominal water output rate of the water purification equipment. For example, the theoretical water output rate of a reverse osmosis water purification equipment with a flux of 400G is 1L / minute, the theoretical water output rate of a reverse osmosis water purification equipment with a flux of 600G is 1.56L / minute, and the theoretical water output rate of a reverse osmosis water purification equipment with a flux of 1200G is 3L / minute.

[0037] Optionally, the water purification device may include a touch button and / or a voice acquisition module, so that the user can trigger the quantitative water extraction instruction and set the water output through the touch button and / or the voice acquisition module. Of course, when the water purification device is bound to the user terminal, the user can also trigger the quantitative water extraction instruction and set the water output through a preset application on the user terminal, that is, the water purification device can also obtain the quantitative water extraction instruction and set the water output sent by the preset application on the user terminal, which improves the flexibility of user use and allows the user to select the control method of quantitative water extraction according to actual needs. This embodiment does not limit the triggering method of the quantitative water extraction instruction.

[0038] S202: Correct the theoretical water outlet speed of the water purification device according to the water outlet speed correction parameter to obtain the estimated water outlet speed of the water purification device.

[0039] After obtaining the water outlet speed correction parameter, the theoretical water outlet speed can be corrected using the water outlet speed correction parameter. For example, the ratio between the theoretical water outlet speed and the parameter value of the water outlet speed correction parameter can be determined as the estimated water outlet speed of the water purification device.

[0040] In this embodiment, the flow meter is not used directly to measure the actual water outlet speed of the water purification equipment. Instead, various factors affecting the operation of the water purification equipment are comprehensively considered, and the determined water outlet speed correction parameters are used by software to correct the theoretical water outlet speed of the water purification equipment. This makes the estimated water outlet speed closer to the actual water outlet speed, improves the accuracy of quantitative water extraction, and does not increase the structural complexity and manufacturing cost of the water purification equipment.

[0041] S203: Determine the water output duration according to the water output corresponding to the quantitative water intake instruction and the estimated water output speed.

[0042] Among them, the quantitative water extraction instruction can carry the water output required by the user. After obtaining the estimated water output speed of the water purification equipment, the ratio between the water output and the estimated water output speed can be determined as the water output time required for the quantitative water extraction process.

[0043] S204, controlling the water purification equipment to execute a quantitative water intake task according to the water output time.

[0044] After the water output time is obtained, the water purification device is controlled to perform the quantitative water extraction task according to the water output time. Optionally, the timing is started after the water production is started, and when the timing reaches the calculated water output time, the water purification device is controlled to stop water output, thereby achieving the purpose of quantitative water output.

[0045] In actual applications, when triggering a quantitative water extraction instruction, the user can also set the purpose of this quantitative water extraction, that is, the above-mentioned quantitative water extraction instruction may carry water extraction purpose information. In this case, optionally, the above-mentioned S204 may include: determining the required water outlet temperature of the water purification equipment according to the water extraction purpose information carried in the quantitative water extraction instruction; controlling the water purification equipment to perform the quantitative water extraction task according to the required water outlet temperature and water outlet time.

[0046] Among them, the above-mentioned water use information indicates the purpose of quantitative water intake, for example, the water use may include making tea, making milk, making coffee, medical water, baby water, cooking, etc. Each water use information corresponds to a certain water outlet demand temperature, and there may be differences between the water outlet demand temperatures corresponding to each water use information. For example, the water outlet demand temperature corresponding to making tea is higher, and the water outlet demand temperature corresponding to making milk is relatively lower. Therefore, after the water production is started, the water outlet demand temperature of the water purification equipment can be determined based on the water use information, and the water purification equipment can be controlled to perform the heating operation according to the water outlet demand temperature, and the water purification equipment can be controlled to discharge water according to the water outlet time calculated above, so that the actual water output and actual water outlet temperature of the water purification equipment can meet user needs, thereby improving the intelligence of the water purification equipment.

[0047] The control method of the water purification equipment provided in the embodiment of the present application fully considers the influence of various factors on the water outlet speed of the water purification equipment, and corrects the theoretical water outlet speed of the water purification equipment through the current water outlet speed correction parameter of the water purification equipment, so as to obtain a more accurate water outlet speed, which is then converted into water outlet time, and the water purification equipment is controlled to perform the quantitative water intake task through the water outlet time, thereby ensuring the accuracy of the water output of the quantitative water intake function.

[0048] In one embodiment, optionally, Figure 3 As shown, the current water outlet speed correction parameter of the water purification device determined in S201 may include:

[0049] S301. Collect the current water inlet temperature of the water purification equipment through a temperature sensor.

[0050] Among them, the TDS probe of the water purification equipment can be integrated with a temperature sensor. The inlet water temperature will affect the water outlet speed of the water purification equipment. The lower the inlet water temperature, the higher the viscosity of the water, and the slower the water outlet speed. Therefore, the inlet water temperature of the water purification equipment can be collected through the temperature sensor integrated in the TDS probe. Of course, a temperature sensor can also be set in the water inlet pipeline of the water purification equipment to collect the inlet water temperature of the water purification equipment.

[0051] S302: Determine a first water outlet speed correction coefficient corresponding to the water inlet temperature.

[0052] After the inlet water temperature is collected, the inlet water temperature will correspond to a first water outlet speed correction coefficient. Optionally, the inlet water temperature can be compared with a standard water temperature, and the first water outlet speed correction coefficient corresponding to the inlet water temperature can be determined based on the comparison result. The standard water temperature corresponds to the theoretical water outlet speed.

[0053] As an optional implementation, the process of S302 may be: querying a preset mapping relationship table based on the inlet water temperature to obtain a first water outlet speed correction coefficient corresponding to the inlet water temperature.

[0054] The preset mapping relationship table includes the correspondence between different water inlet temperatures and the first water outlet speed correction coefficient. Specifically, the preset mapping relationship table can be constructed based on a large amount of experimental data. After the water inlet temperature is obtained, the first water outlet speed correction coefficient corresponding to the water inlet temperature can be obtained by looking up the table.

[0055] S303: Determine the current second water outlet speed correction coefficient of the target reverse osmosis filter element.

[0056] During the long-term use of the water purification equipment, the target reverse osmosis filter element will inevitably experience flow attenuation due to blockage caused by pollution of the target reverse osmosis filter element. Therefore, the current second water outlet speed correction coefficient of the target reverse osmosis filter element can be determined based on the usage of the target reverse osmosis filter element.

[0057] As an optional implementation method, the above-mentioned S303 process can be: collecting actual water outlet flow rates of multiple sample reverse osmosis filter elements of the same specification as the target reverse osmosis filter element at different usage time points; determining the flow attenuation curve of the target reverse osmosis filter element based on the water outlet flow rates of each sample reverse osmosis filter element at different usage time points and the nominal water outlet flow rate before use; determining the current second water outlet speed correction coefficient of the target reverse osmosis filter element based on the cumulative usage time and the flow attenuation curve of the target reverse osmosis filter element.

[0058] Specifically, by selecting multiple sample reverse osmosis filter elements of the same specification as the target reverse osmosis filter element for testing, that is, collecting the water outlet flow rate of each sample reverse osmosis filter element at different use time points during its service life, and determining the flow attenuation of each sample reverse osmosis filter element as the use time increases during its service life based on the ratio between the water outlet flow rate of each sample reverse osmosis filter element at different use points and the nominal water outlet flow rate before use, and then generating a flow attenuation curve of the target reverse osmosis filter element during its service life based on the flow attenuation of each sample reverse osmosis filter element. Among them, the flow attenuation curve characterizes the corresponding relationship between different use times and the second water outlet speed correction coefficient. Furthermore, based on the cumulative use time and flow attenuation curve of the target reverse osmosis filter element, the current second water outlet speed correction coefficient of the target reverse osmosis filter element is determined.

[0059] Correspondingly, optionally, the above S202 may include: correcting the theoretical water outlet speed of the water purification device according to the first water outlet speed correction coefficient and the second water outlet speed correction coefficient to obtain the estimated water outlet speed of the water purification device.

[0060] For example, the estimated water outlet speed v of the water purification device can be calculated according to the following formula: 预估 :

[0061] v 预估 =v 理论 / ɑ / β;

[0062] Among them, v 理论 is the theoretical water outlet speed of the water purification equipment, ɑ is the first water outlet speed correction coefficient, and β is the second water outlet speed correction coefficient.

[0063] In this embodiment, the water inlet temperature of the water purification equipment and the state of the target reverse osmosis filter element are comprehensively considered, and a corresponding water outlet speed correction coefficient is introduced to correct the theoretical water outlet speed of the water purification equipment, so that the estimated water outlet speed is closer to the actual operation of the water purification equipment, thereby improving the accuracy of quantitative water extraction.

[0064] In practical applications, the water inlet pressure of the water purification equipment will also affect the water outlet speed. Therefore, in one embodiment, optionally, Figure 4 As shown, before determining the current water outlet speed correction parameter of the water purification device, the method further includes:

[0065] S401. Collect the water inlet pressure of the water purification equipment through a pressure sensor.

[0066] Among them, a pressure sensor is arranged in the water inlet pipeline of the water purification equipment, and the water inlet pressure of the water purification equipment is collected through the pressure sensor.

[0067] S402: When the water inlet pressure is within a preset water pressure range, a step of determining a current water outlet speed correction parameter of the water purification device is executed.

[0068] S403: When the water inlet pressure is less than the lower limit of the preset water pressure range, the quantitative water intake function is turned off, and a prompt message indicating that the quantitative water intake function is unavailable is output.

[0069] The preset water pressure interval is a water pressure range that can ensure the normal water output of the water purification equipment. Usually, the reverse osmosis water purification equipment generally requires an inlet pressure of 0.1-0.4MPa, and the preset water pressure interval can be set based on this. When the collected inlet pressure is within the preset water pressure interval, the quantitative water intake control logic described in the above embodiments S201-S204 is executed, that is, the theoretical water output speed of the water purification equipment is corrected in combination with the inlet water temperature and the target reverse osmosis filter element state to achieve the accuracy of quantitative water intake.

[0070] When the water inlet pressure is less than the lower limit of the preset water pressure range, the water inlet flow rate will decrease, resulting in a decrease in the water outlet flow rate. This is an abnormal working condition, and the user's waiting time is too long, and it is difficult to meet the user's quantitative water intake needs. In this case, the quantitative water intake function can be turned off, and the user is prompted that the quantitative water intake function is unavailable. Optionally, the user can also be prompted for the reason why the quantitative water intake function is unavailable, such as outputting a prompt message "The quantitative water intake function is temporarily turned off due to insufficient water inlet pressure."

[0071] Optionally, the water purification device may further include a speaker, and while turning off the quantitative water extraction function, a voice prompt message indicating that the quantitative water extraction function is unavailable may be output through the speaker. Optionally, the water purification device may further include an indicator light arranged on the faucet, and the indicator light may display a specific color to indicate that the quantitative water extraction function is unavailable. For example, when the quantitative water extraction function is unavailable, the indicator light may be set to red, and after the quantitative water extraction function is restored, the indicator light may be set to green. In this way, the color change of the indicator light helps the user to better understand whether the quantitative water extraction function is available. Of course, a display screen may also be provided on the water purification device, and the data module on the display screen may be used to indicate that the quantitative water extraction function is unavailable. Regardless of whether an indicator light, a speaker or a display screen is provided, as long as the effect of prompting that the quantitative water extraction function is unavailable is achieved, these do not deviate from the principles of the present application, and therefore will fall within the scope of protection of the present application.

[0072] In this embodiment, in addition to considering the effects of the inlet water temperature and the target reverse osmosis filter element state on the water output speed of the water purification equipment, the effect of the inlet water pressure on the water output speed is also considered, thereby improving the accuracy of quantitative water extraction. In addition, when the water output cannot meet user needs, the quantitative water extraction function is turned off and a prompt message indicating that the quantitative water extraction function is not available is output, thereby improving the intelligence of the water purification equipment and enhancing the user experience.
