[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] With the improvement of modern living standards, people's requirements for drinking water quality are getting higher and higher. Traditional faucets only meet the basic water discharge function and can no longer meet the needs of modern families for water quality monitoring, mineralization, aesthetics and other aspects. Therefore, a new type of faucet that integrates water quality monitoring, mineralization and intelligent display has come into being, namely the mineralization faucet. The mineralization faucet not only has the basic water discharge function, but also can monitor water quality in real time, improve water quality through mineralization filter elements, and provide intuitive water quality information and operation interface through intelligent display modules.

[0051] See also Figure 1 Shown is a schematic diagram of the structure of the mineralization faucet provided in an embodiment of the present application.

[0052] The mineralized faucet is mainly composed of the following parts: faucet body, display module, filter element assembly, control module, detection module, communication module and radar.

[0053] The faucet body is the main structure of the mineralized faucet, including a connecting part and a main body. The connecting part and the main body are connected by rotation, which is convenient for the user to adjust the angle and position of the faucet. An installation area is provided on the main body for installing a display module. At least one display area is provided on the connecting part or the main body for installing a light-emitting unit.

[0054] The display module is used to display the user interface, etc. The user interface can have multiple display areas to meet the display requirements of different information. A light-emitting unit can also be set in the display area to provide backlight or indication functions. The color or length can be changed according to the instructions of the control module to intuitively reflect the water quality status or remind the user to perform certain operations.

[0055] The detection module is arranged on the water supply channel, and is used to obtain the dissolved matter content value (for example, the total dissolved solid value or the conductivity) of the water supply channel, and transmit the obtained dissolved matter content value to the control module for processing. The detection module includes a detection meter.

[0056] The filter element assembly is used to mineralize the water flow in the water supply waterway. The filter element assembly is set in the water supply waterway to improve the water quality through the mineralized filter element, providing healthier and better tasting drinking water. The filter element assembly includes an inlet end and an outlet end, and the inlet end and the outlet end are respectively provided with a detector.

[0057] The control module is the intelligent core of the mineral faucet, which is connected to the display module, light-emitting unit, etc., and is used to control the color or length of the light-emitting unit and the display content of the display module. The control module can intelligently adjust the water quality according to the user's biological information to meet the user's personalized needs.

[0058] The communication module is used to communicate with the control module to achieve remote control and data transmission. The communication module can transmit the soluble substance content value to a remote device or server, which is convenient for users to view and manage at any time.

[0059] Radar can be used to sense the user's approach or departure, thereby automatically turning off the faucet and achieving a more convenient and energy-saving water use experience. Radar can also be used in conjunction with other water quality monitoring sensors to build a water quality monitoring system. When the water quality is abnormal, the radar can cooperate with the display module and the light-emitting unit to send out an early warning signal to remind the user to deal with it in time.

[0060] The mineralized faucet can be connected to a water purifier and users can conveniently obtain mineralized and purified drinking water through the mineralized faucet to meet the daily drinking water needs of the family.

[0061] Figure 2 The present invention provides a flow chart of a method for regulating the quality of effluent water according to an embodiment of the present invention. The method for regulating the quality of effluent water includes the following steps.

[0062] S21, obtaining the user's biometric information.

[0063] Bioinformation refers to the information generated by organisms at the genetic, physiological, ecological and other levels. The bioinformation includes biometric information (such as fingerprints, irises, faces, etc.) and physiological information (such as heart rate, blood pressure, blood sugar, etc.).

[0064] One or more sensors may be arranged on the mineralized faucet to directly obtain the biological information of the water user through the one or more sensors. One or more sensors may also be arranged near the mineralized faucet to obtain the biological information of the water user through the one or more sensors and then send it to the mineralized faucet.

[0065] Different types of sensors can be set up accordingly according to the categories of biometric information that need to be obtained. For example, a fingerprint recognition sensor is embedded on the surface of the mineralized faucet to facilitate user touch; a facial recognition sensor is installed on the wall or ceiling near the mineralized faucet to record the facial features of the user who draws water; an infrared body temperature sensor is installed on the side or above the mineralized faucet to measure the user's body temperature; a heart rate monitoring sensor in the form of a bracelet or grip is designed on the mineralized faucet, and the user naturally touches it when using it to monitor the heart rate of the user who draws water; a touch-type skin conductivity sensor is designed, and the user can measure the body's water status with a light touch when using the mineralized faucet. The embodiments of the present application do not impose any restrictions on the installation location, number of installations, and type of sensors. As long as the required biometric information can be accurately and reliably obtained, the sensors can be flexibly selected and configured according to actual needs to achieve a smarter and safer mineralized faucet system.

[0066] S22, determining a recommended water quality range according to the biological information.

[0067] The recommended water quality range refers to a standard range of water quality suitable for drinking, customized based on the user's biological information, to meet the needs of different groups of people for healthy drinking water.

[0068] A correspondence table between biological information and recommended water quality ranges is pre-stored in the mineralized faucet, and the recommended water quality range that matches the biological information of the water user can be queried based on the correspondence table.

[0069] In an optional implementation, determining the recommended water quality range according to the biological information includes:

[0070] determining the age group of the user according to the biometric information;

[0071] The recommended water quality range is determined based on the age group mentioned.

[0072] Among them, the biological information may include one or more combinations of the following: heart rate, blood pressure, blood sugar. Heart rate, blood pressure, and blood sugar are indicators that reflect the physiological condition of the human body, and there is a certain correlation between them and the age group. By analyzing the changing trends of these indicators in different age groups, the approximate age group of a person can be inferred. For example, the heart rate gradually decreases with age: the heart rate of newborns is faster, usually more than 100 beats / minute; the heart rate of children to adolescents gradually drops to the normal range, but is still higher than that of adults; the normal range of heart rate in adults is relatively wide, generally between 60-100 beats / minute; the heart rate level of the elderly is lower than when they were young, but it is still within a certain range. For example, with the increase of age, blood pressure usually tends to rise gradually: blood pressure in childhood is relatively low; and blood pressure in the elderly is relatively high.

[0073] Minerals are essential trace elements for the human body, but people of different ages have different requirements for minerals, and people of different ages have different adaptability to the pH value of water. For example, children have weaker immune systems and may be more suitable for drinking water that is close to neutral to avoid irritation to the gastrointestinal tract. It is recommended to drink high-purity water with a pH value between 6.8-7.2 and a moderate mineral content. Adults are recommended to drink water with a pH value between 6.5-7.5 and a suitable mineral content. The elderly may need water containing an appropriate amount of minerals such as calcium and magnesium to supplement their body needs.

[0074] A first correspondence between a combination of one or more of heart rate, blood pressure, and blood sugar and an age group can be established in advance, and a second correspondence between an age group and a recommended water quality range can be established. The target age group matching the combination of one or more of heart rate, blood pressure, and blood sugar is queried through the first correspondence. After the age group is queried, the recommended water quality range matching the age group is queried through the second correspondence.

[0075] The above optional implementation method determines the age group based on biological information, thereby providing personalized recommended water quality ranges for groups of different age groups, thereby improving the intelligence level of water quality regulation and meeting the personalized needs of people of different age groups.

[0076] In another optional implementation, determining the recommended water quality range according to the biological information includes:

[0077] Perform identification based on the biometric information to obtain personalized features of the user;

[0078] A recommended water quality range is determined based on the personalized characteristics.

[0079] The biometric information may include one or more of the following combinations: face image, iris image, etc.

[0080] As a form of biometrics, facial images and iris images are unique and identifiable, and can therefore be used to provide personalized services to users.

[0081] The facial features or iris features of the water-collecting user can be identified based on the face image or iris image, and compared with the user information stored in the database. Through the comparison, the system can confirm the identity of the user. After confirming the identity of the user, personal information associated with the user can be retrieved from the user database, such as the user's health status, eating habits, drinking water preferences, etc., which are all registered by the user in advance or entered during use. Based on the retrieved user personal information, the recommended water quality range suitable for the user can be further analyzed and determined. For example, if the user has specific health problems (such as kidney disease), water with a lower mineral content can be recommended. Or, if the user prefers water with a sweet taste, mineral water containing a certain amount of minerals can be recommended.

[0082] AI models (deep learning algorithms and convolutional neural networks (CNN), etc.) can also be used to learn a large number of facial images and related health data or facial micro-expressions, eye expressions, etc., to establish a correlation model between facial features and health conditions. In this way, when a facial image of a water user is obtained, the facial image is included in the AI ​​model, and the AI ​​model makes judgments on physiological health status, facial micro-expressions, eye expressions, etc. based on the learned features. In this way, the recommended water quality range is determined based on the correspondence between the pre-established and stored physiological health status, facial micro-expressions, eye expressions, etc. and the recommended water quality range.

[0083] The above optional implementation method identifies the user's personalized characteristics based on biometric information, and determines the recommended water quality range based on the personalized characteristics, thereby providing each user with customized water quality options, which not only improves the personalization level of water quality adjustment, but also provides users with a more convenient and comfortable user experience.

[0084] S23, displaying the recommended water quality range in the water quality display area of ​​the mineral faucet.

[0085] The mineralization faucet of the embodiment of the present application provides a display interface, such as Figure 3As shown, the display interface includes a water quality display area, an operation control area and a status display area. The water quality display area serves as an intuitive window for users to obtain water quality information. By displaying the determined recommended water quality range on the water quality display area of ​​the mineralized faucet, users can clearly see the suitable water quality range recommended by the mineralized faucet based on their own biological information. Users no longer need to perform tedious water quality testing and comparisons, but can simply check the water quality display area of ​​the mineralized faucet to quickly understand the water quality range recommended for them. It is convenient for users to choose drinking water more scientifically based on the recommended water quality range, thereby protecting their own health.

[0086] The intelligent recommendation system of the mineralized faucet does not display information in a fixed manner, but adopts a flexible and diverse display method to adapt to the needs and preferences of different users. In specific implementation, the recommended water quality range can be displayed in the water quality display area of ​​the mineralized faucet according to the user's biological information.

[0087] An optional implementation is to customize the display mode (i.e., the first display mode) according to the age group of the user, and display the recommended water quality range in the water quality display area of ​​the mineral faucet according to the first display mode. For children, the system may use more lively and colorful icons and animations to display the recommended water quality, and at the same time provide simple and easy-to-understand text descriptions to ensure that the information is conveyed accurately and attractively. For middle-aged and elderly users, the system may prefer to use clear and concise text and graphics to reduce the reading burden and improve the readability of the information.

[0088] Another optional implementation is to customize the display mode (i.e., the second display mode) according to the personalized characteristics of the user, and display the recommended water quality range in the water quality display area of ​​the mineral faucet according to the second display mode. For users with special health needs, the system can highlight those water quality parameters that can meet their specific health needs in the water quality display area, such as low sodium, high calcium, etc., and attach corresponding health tips and suggestions to help users make more informed choices.

[0089] The above optional implementation method not only realizes the intelligent water quality recommendation by visually displaying the recommended water quality range in the water quality display area, but also improves the user's sense of participation and satisfaction through personalized display. Users are no longer passive recipients, but become active participants in the entire intelligent recommendation process, and can easily obtain and understand water quality information suitable for them according to their actual situation and needs.

[0090] S24, receiving a water output instruction triggered by the user in the operation control area of ​​the mineral faucet according to the recommended water quality range.

[0091] After viewing the water quality range recommended by the mineral faucet, the user can enter the desired water quality, for example, PH7.5, according to their actual needs and preferences by touching or clicking the water quality display area of ​​the mineral faucet or the mobile phone APP interface. After the mineral faucet detects the user's touch or click operation, it triggers the water output instruction according to the touch or click operation.

[0092] S25, controlling the mineral faucet to discharge water according to the water discharge instruction.

[0093] In order to respond to user needs accurately and quickly, the mineralized faucet analyzes the water output command to extract the water quality expected by the user. Then, the mineralized faucet automatically adjusts its internal filtering, mineralization or purification devices according to the water quality parameters. These devices can include different types of filter elements, mineralized balls, ultraviolet sterilizers, etc., which can accurately adjust the pH value of the water quality to meet the specific needs of users.

[0094] In an optional embodiment, controlling the mineralized faucet to discharge water according to the water discharge instruction includes:

[0095] Obtaining the expected outlet water quality in the outlet water instruction;

[0096] Determining an expected soluble matter content difference according to the expected effluent water quality;

[0097] Obtaining the actual soluble substance content difference of the mineralized tap;

[0098] The mineralized faucet is controlled to discharge water according to the expected soluble substance content difference and the actual soluble substance content difference.

[0099] By collecting a large amount of experimental data, such as different upstream and downstream soluble substance content values, and water samples with different pH values, a corresponding relationship model between the soluble substance content difference (the difference between the upstream and downstream soluble substance content values) and the pH value is established, such as Figure 4 The ΔTDS-PH curve shown. The mineralized faucet finds the difference in dissolved matter content (expected difference in dissolved matter content) corresponding to the expected effluent water quality based on the established ΔTDS-PH curve.

[0100] The mineralization faucet monitors the actual soluble substance content values ​​of the upstream and downstream according to the upstream and downstream sensors, and calculates the actual soluble substance content difference based on the actual soluble substance content values ​​of the upstream and downstream.

[0101] Finally, according to the desired soluble substance content difference and the actual soluble substance content difference, the working state (such as flow rate, time, temperature, etc.) of the filtering, mineralizing or purifying device inside the mineralizing faucet is adjusted to change the soluble substance content of the water outlet so that it gradually approaches the water quality expected by the user. Assuming that the desired soluble substance content difference is ΔTDS_desired and the actual soluble substance content difference is ΔTDS_actual, the flow value that needs to be adjusted is calculated according to the difference between ΔTDS_desired and ΔTDS_actual, and the response characteristics of the system (such as the influence coefficient of flow change on ΔTDS change), so as to control the water outlet according to the flow value that needs to be adjusted.

[0102] In the process of controlling the water output, the system will also monitor the water quality of the output water in real time and make fine adjustments according to the actual situation. If there is still a large gap between the output water quality and the user's expected water quality, the system will continue to adjust the working state of the mineral faucet until the output water quality meets the user's requirements.

[0103] The above optional implementation method controls the water output of the mineralized faucet according to the difference between the expected soluble substance content and the actual soluble substance content, which not only takes into account the water quality expected by the user, but also combines the actual current working state of the mineralized faucet to achieve more accurate and efficient water quality regulation. This application not only improves the accuracy and efficiency of water quality regulation, but also ensures that users can obtain stable, reliable and expected water quality services. This intelligent control method enables the mineralized faucet to better meet the personalized needs of users and improves the satisfaction of user experience.

[0104] In an optional embodiment, the controlling the mineralized faucet to discharge water according to the expected soluble substance content difference and the actual soluble substance content difference includes:

[0105] Obtaining an expected deviation according to the expected soluble substance content difference and the actual soluble substance content difference;

[0106] Calculating a flow adjustment amount based on the desired deviation using a proportional-integral-derivative control module;

[0107] The mineralized faucet is controlled to discharge water according to the flow adjustment amount.

[0108] The difference is calculated based on the expected soluble substance content difference and the actual soluble substance content difference to obtain the expected deviation. By calculating the expected deviation, the difference between the expected soluble substance content difference (expected state) and the actual soluble substance content difference (actual state) can be quantified, providing a clear reference for subsequent control operations.

[0109] If the difference in the expected soluble substance content is greater than the difference in the actual soluble substance content (ΔTDS_desired>ΔTDS_actual), it indicates that the soluble substance content in the current water outlet is lower than the expected soluble substance content. In other words, the content of minerals or other soluble substances in the water is insufficient, and the water quality PH cannot meet the needs of users. It is necessary to increase the water flow rate of the mineralization faucet or increase its water outlet speed, shorten the residence time of water in the mineralizer, so as to increase the soluble substance content in the water outlet, so that it approaches or reaches the expected water quality. If the difference in the expected soluble substance content is less than the difference in the actual soluble substance content (ΔTDS_desired<ΔTDS_actual), it indicates that the soluble substance content in the current water outlet is higher than the expected soluble substance content. In other words, the content of minerals or other soluble substances in the water is too much, and the water quality PH exceeds the needs of users. It is necessary to reduce the water flow rate of the mineralization faucet or reduce its water outlet speed, and extend the residence time of water in the mineralizer to reduce the soluble substance content in the water outlet, so that it approaches or reaches the expected water quality. If the desired soluble substance content difference is equal to the actual soluble substance content difference (ΔTDS_desired=ΔTDS_actual), it means that the soluble substance content in the current water outlet is exactly equal to the desired soluble substance content difference. In other words, the content of minerals or other soluble substances in the water has reached the desired standard, and the water quality PH just meets the user's needs. At this time, there is no need to make any adjustments to the water flow rate of the mineral faucet. The current water outlet state can be maintained, and the water quality of the outlet water can continue to be monitored to ensure its stability.

[0110] In order to smoothly adjust the flow rate and reduce overshoot and oscillation, a proportional-integral-differential (PID) control module is used for control. The PID control module calculates the flow adjustment amount based on the expected deviation, that is, the degree of water quality adjustment required. The flow valve opening of the mineral faucet outlet is adjusted according to the calculated flow adjustment amount to adjust the water flow rate or water speed, thereby controlling the water quality of the mineral faucet. The PID control module can comprehensively consider the current value, past value and change trend of the deviation to calculate a more accurate and stable flow adjustment amount, which helps to achieve precise control of the water outlet of the mineral faucet and achieve effective use and conservation of water resources.

[0111] Input of PID control module: expected deviation between expected dissolved substance content difference (ΔTDS_desired) and actual dissolved substance content difference (ΔTDS_actual), that is, e(t) = ΔTDS_desired-ΔTDS_actual. The expected deviation reflects the difference between the current effluent water quality and the target water quality, and is the basis for the control module to make adjustments.

[0112] The output of the PID control module: the water flow adjustment of the mineral faucet u(t) = Kp×e(t)+Ki×∫e(t)dt+Kd×de(t) / dt, is used to control the content of dissolved substances in the water. The flow adjustment is calculated based on the deviation e(t) and the historical changes of the deviation (calculated by integration and differentiation), aiming to achieve precise control of the water quality.

[0113] Among them, Kp is the proportional coefficient, which determines the degree of immediate response of the control module to the deviation. When the deviation is large, the proportional term will produce a large adjustment amount to quickly reduce the deviation. However, too large a proportional coefficient may cause the system to overshoot and oscillate. Ki is the integral coefficient, which is used to eliminate the static error of the system. It compensates for the accumulation of deviations (i.e., integration) to ensure that the system can eventually reach the desired steady-state value. The existence of the integral term helps to smooth the transition process of the system and reduce overshoot and oscillation. Kd is the differential coefficient, which is used to predict the future change trend of the deviation and compensate in advance. It suppresses the rapid changes of the system by reacting to the rate of change of the deviation (i.e., differential), thereby enhancing the stability and response speed of the system.

[0114] In the above optional implementation mode, the PID control algorithm is used to continuously sample deviations and calculate flow adjustment amounts. The control system can adjust the water flow rate of the mineral faucet in real time to ensure that the content of soluble substances in the outlet water reaches the expected value, thereby indirectly controlling the pH value of the outlet water, thereby achieving precise control of the outlet water quality and effective use of water resources.

[0115] In an optional embodiment, the method further comprises:

[0116] Obtaining the working status of the mineralization faucet;

[0117] The working status is displayed in the status display area of ​​the mineralization faucet.

[0118] The system obtains the current working status of the mineral faucet in real time through built-in sensors or external device interfaces (such as Internet of Things technology). The current working status can include key operating parameters such as water flow, pressure, temperature, remaining filter life, device networking status, fault code, water quality PH value, etc.

[0119] The acquired working status information will be displayed in real time on the status display area of ​​the mineralization faucet, allowing users to intuitively understand the operating status of the equipment, facilitating daily maintenance and troubleshooting.

[0120] The remaining life information of the filter element will be presented to the user in an intuitive manner in the status display area, such as a percentage progress bar, remaining days or recommended replacement date, etc., which helps users replace the filter element in time to ensure the water quality.

[0121] The mineral faucet has IoT functionality and can connect to a home network or cloud server. Network status information (such as Wi-Fi signal strength, network latency, etc.) will be displayed in the status display area to ensure that users understand the network connection status of the device. If the network connection is lost, the system will issue a warning and prompt the user to check the network settings.

[0122] The current water flow rate is displayed in real time, allowing users to understand the water output efficiency of the device. If the water flow rate is lower than the preset value, the system will issue a warning, prompting the user to check whether the water pipe is blocked or whether the device needs maintenance.

[0123] When a device fails, the system will automatically detect and generate a corresponding fault code. The fault code will be displayed in the status display area, and the system will provide possible fault causes and solution suggestions. Users can quickly locate the problem based on the fault code and take corresponding solutions to improve the reliability and stability of the device.

[0124] The above optional implementation methods greatly improve the user experience and the intelligence level of the equipment by adding functions such as filter element remaining life prediction, equipment networking status monitoring, recommended water quality parameter presentation, water flow display and fault code prompt.

[0125] In an optional embodiment, the method further comprises:

[0126] Monitoring the actual water quality of the mineralized faucet;

[0127] Comparing the actual effluent water quality with a preset standard water quality range;

[0128] When the actual outlet water quality is not within the preset standard water quality range, the mineral faucet is controlled to sound an alarm.

[0129] A first sensor is arranged upstream of the filter element, and the first sensor is used to detect the soluble substance content value upstream of the filter element (i.e., the first soluble substance content value). The first soluble substance content value is the soluble substance content value before the water flows through the filter element, that is, the soluble substance content value of the raw water. Similarly, a second sensor is arranged downstream of the filter element, and the second sensor is used to detect the soluble substance content value downstream of the filter element (i.e., the second soluble substance content value). The second soluble substance content value is the soluble substance content value after the water flows through the filter element. The target soluble substance content difference is obtained according to the first soluble substance content value and the second soluble substance content value.

[0130] In order to calculate the pH value of water quality based on the target soluble substance content difference, it is necessary to collect water quality sample data from different water sources and conditions in advance, and fit the possible correlation or functional relationship between the soluble substance content difference and the pH value based on the water quality sample data, and then use the fitted correlation or functional relationship to calculate the pH value of water quality based on the target soluble substance content difference.

[0131] The soluble matter content value is usually used to measure the total amount of dissolved matter in water, which may include salts, minerals, organic matter, etc. By detecting the soluble matter content value, the quality of water and the effect of water treatment equipment can be evaluated. In the embodiment of the present application, in order to more accurately monitor the water quality pH in the water treatment equipment, the soluble matter content value may include a total dissolved solids value or conductivity. The total dissolved solids (TDS) value refers to the total amount of solids dissolved in water, including the content of both inorganic and organic matter. The unit of measurement is milligrams per liter (1 mg / L = 1 ppm), indicating how many milligrams of total dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more dissolved matter is contained in the water. Generally, the conductivity value can be used to roughly understand the salt content in the solution. The higher the conductivity, the higher the salt content, and the higher the TDS value. A TDS sensor is an instrument that reflects the degree of mineralization of water quality by measuring the conductivity of water. Conductivity is an indicator of the ion concentration in water, which reflects the ability of dissolved substances in water to conduct electricity. Dissolved substances in water form ions, which can transmit electric current when moving in water, so conductivity can be used to evaluate the ion concentration in water. The higher the conductivity, the higher the ion concentration in the water, which may contain more dissolved substances. During the water treatment process, conductivity can be used to monitor changes in water quality and evaluate the effectiveness of water treatment equipment.

[0132] When the actual water quality is not within the preset standard water quality range, the system will control the mineral faucet to sound an alarm. The alarm method may include sound alarm, light alarm or screen display alarm. For example, the system can sound an alarm through the built-in speaker, or remind the user through the red warning light or flashing expression icon in the display area. This intuitive visual feedback can quickly attract the user's attention and remind the user to take timely measures to deal with it.

[0133] In order to more intuitively display the water quality, the system can use colored light bars, colored rings, expressions or numerical values ​​to feedback the pH value or TDS value. The colored light bars or colored rings can change colors according to the pH value range, such as green for good water quality, yellow for average water quality, and red for poor water quality. The expression icons can be designed in a more vivid and interesting style, such as a smiling face for water quality that meets the standard and a crying face for water quality that does not meet the standard. The numerical display can directly show the precise value of the pH value or TDS value to the user, so that the user can make a more accurate judgment.

[0134] The above optional implementation method further improves the user experience and the intelligence level of the equipment by adding real-time monitoring and alarm functions of actual effluent water quality, as well as a more intuitive pH value feedback mechanism.

[0135] The method for adjusting the water quality of the outlet water provided in the embodiment of the present application can recommend water quality ranges for different groups of people by obtaining the biological information of the user, which helps to meet the personalized needs of different groups of people for drinking water and ensure that all types of people can obtain drinking water that best suits their physical needs. A water quality display area is set on the mineralized faucet, which can intuitively display the recommended water quality range, so that users can clearly understand the water quality requirements suitable for their bodies. At the same time, users can also trigger water outlet instructions in the operation control area of ​​the mineralized faucet, and control the water outlet according to the water outlet instructions, which improves the user's operational convenience and experience. Compared with traditional water purifier products with a single function, this application makes the water purifier product have stronger functionality and flexibility by intelligently adjusting the outlet water quality. The outlet water quality can be flexibly adjusted according to the actual needs of the user, thereby improving the applicability and market competitiveness of the mineralized faucet.
