Description

Technical Field

[0001] The present application relates to the technical field of water treatment equipment, and in particular to a water quality information display method, device, water treatment equipment and storage medium. Background Art

[0002] With the development of social economy, people are paying more and more attention to the quality of drinking water. In the field of water purification technology, adding alkaline filter materials to water treatment equipment has become an important means to improve water quality. When in contact with water flow, alkaline filter materials can release mineral ions that are beneficial to human health, such as calcium ions, magnesium ions, potassium ions, etc., and effectively adjust the pH value (acidity and alkalinity) of the effluent water. The pH value of drinking water treated with alkaline filter materials can approach the ideal target pH value range, such as between 6.5 and 8.5, which helps maintain the acid-base balance in the human body and has a positive impact on human health.

[0003] In actual applications, during the use of water treatment equipment, the pH value may not be within the above target pH range. For example, when the alkaline filter material is first used, it has abundant surface active sites and strong ion exchange capacity, which will release a large amount of mineral ions into the water in a short period of time, causing the water quality pH value to exceed the upper limit of the target pH range. On the other hand, as the alkaline filter material is used for a longer period of time and approaches its service life cycle, the ion exchange active sites inside the filter material decrease, and its ability to release mineral ions decreases significantly, and the pH value may be lower than the lower limit of the target pH range. Existing technologies usually recommend that users do not use water that exceeds the above target pH range, or replace the alkaline filter material in a timely manner. However, this results in a poor user experience and fails to maximize the potential of the alkaline filter material. Summary of the invention

DETAILED DESCRIPTION

[0018] 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 only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] The water quality information display method provided in the embodiment of the present application is mainly used in water treatment equipment in home life or office places to monitor and control the pH value of the water quality of the water treatment equipment.

[0020] Water treatment equipment is a device used to improve water quality, remove impurities from water or adjust water quality, such as a water purifier, a water purifier machine, etc. The water treatment equipment in the embodiment of the present application is a water purifier with a mineral mineralization function. A water purifier with a mineral mineralization function refers to a type of water purification equipment that can deeply purify tap water and add mineral elements required by the human body to make the water quality reach a standard similar to that of mineral water. After removing harmful substances, the water purifier with a mineral mineralization function reincorporates minerals such as calcium, magnesium, iron, and zinc required by the human body into the water by adding mineral-rich filter materials. These minerals exist in an ionic state and are easier for the human body to absorb.

[0021] The water treatment equipment may include a filter element assembly, a filter, a reverse osmosis device, etc. The filter element assembly in the embodiment of the present application may include one or more alkaline filter materials, which are a filter element or material used for water treatment, and its main function is to convert acidic water into alkaline water, usually by reducing the acidity of water through negative ions, thereby increasing the alkalinity of water.

[0022] One alkaline filter material corresponds to one alkaline water channel. When multiple alkaline filter materials are used, the water channels between the multiple alkaline filter materials are usually set in parallel to ensure that the water flow can pass through each filter material evenly.

[0023] In the embodiments of the present application, the alkaline filter material contains alkaline substances. For a plurality of alkaline filter materials, the types and dissolution rates of the alkaline substances contained in different alkaline filter materials are different. Therefore, the alkaline strengths of different alkaline filter materials are different, thereby achieving different alkaline treatment effects.

[0024] The following uses two alkaline filter materials as an example to illustrate the interaction between alkaline filter materials and their effects in water treatment: For example, in a filter element assembly, the first alkaline filter material is filled with weakly acidic ore, while the second alkaline filter material is filled with ore rich in calcium and magnesium. When the water flows through the first alkaline filter material first, the acidic substances precipitated from the first alkaline filter material can effectively promote the precipitation of calcium and magnesium in the subsequent second alkaline filter material. This promotion effect not only improves the mineralization efficiency, but also makes the water rich in minerals that are beneficial to the human body after passing through the entire filter element assembly.

[0025] For example, in a filter element assembly, the first alkaline filter material is filled with weakly alkaline ore, while the second alkaline filter material is filled with zinc and copper-containing ore. When the water flows through the first alkaline filter material first, the alkaline substances precipitated from the first alkaline filter material will inhibit the precipitation of zinc and copper elements in the second alkaline filter material. This inhibition relationship can control the content of certain minerals in the water.

[0026] For example, in a filter element assembly, the first alkaline filter material contains alkaline minerals of different contents, while the second alkaline filter material contains calcium magnesium minerals of different contents. By adjusting the flow rate of the water flow channel between the first alkaline filter material and the second alkaline filter material, the concentration of different mineralized elements can be flexibly adjusted to meet the specific needs of different users for water quality.

[0027] In the design of the filter element assembly, the arrangement and combination of different filter materials are also crucial. For example, a combination of a surface strong alkaline material (such as brucite) and an inner weak alkaline material (such as calcite) is used. This design allows the filter element to quickly release strong alkaline substances in the early stage, and as the use time goes by, the inner weak alkaline material gradually takes effect, thus ensuring that the filter element can maintain a moderate alkalinity strength throughout its service life.

[0028] By designing and combining different types of alkaline filter materials and their water channel settings, precise mineralization of water quality can be achieved. This not only helps to improve the safety and health of water quality, but also meets the personalized needs of different users for water taste and nutritional value.

[0029] According to the relevant provisions of the "Sanitary Standards for Drinking Water", the normal pH value of drinking water is 6.5-8.5, because a lower pH value is prone to corroding metal water pipes, while a higher pH value causes the calcium and magnesium ions in the water to precipitate and form scale, which has adverse effects on human health.

[0030] In view of the many benefits of alkaline water to human health and the clear provisions of the pH value of water quality in the "Sanitary Standards for Drinking Water", it is particularly important to accurately monitor the pH value of the water quality of water purifiers with mineral mineralization functions. This is not only related to the safety and health of users' drinking water, but also directly affects the stable operation of the equipment and user experience.

[0031] To achieve this goal, the present application embodiment proposes a water quality information display method for use in water treatment equipment for home life or office. The method aims to ensure that the mineralized water is safe and meets health standards when it reaches the user end by real-time monitoring and regulating the pH value of the water.

[0032] See also Figure 1 The figure is a schematic diagram of the structure of the water treatment equipment provided in the embodiment of the present application.

[0033] The water treatment equipment mainly includes the following parts: a faucet body 1, a display module 2, a filter element assembly 3, a control module 4, a detection module, a communication module 6, a radar 7 and a water pipe 8.

[0034] The faucet body 1 is the main structure of the water treatment equipment, including a connection part and a main body. The connection 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 the display module 2. At least one display area is provided on the main body for installing the light-emitting unit.

[0035] The display module 2 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 information or remind the user to perform certain operations.

[0036] 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 first detection meter 51 and a second detection meter 52.

[0037] The filter element assembly 3 is used to mineralize the water flow in the water supply waterway. The filter element assembly 3 is arranged on the water supply waterway, and the filter element assembly 3 includes one or more alkaline filter materials 31, which improve the water quality through the alkaline filter materials 31 to provide healthier and better tasting drinking water. The filter element assembly 3 includes a water inlet end and a water outlet end, and the water inlet end and the water outlet end are respectively provided with a detector.

[0038] The control module 4 is the intelligent core of the water treatment equipment, which is connected to the display module 2, the 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 2. The control module 4 can intelligently adjust the water quality according to the user's biological information to meet the user's personalized needs.

[0039] The communication module 6 is used to communicate with the control module 4 to realize remote control and data transmission. The communication module 6 can transmit the soluble substance content value to a remote device or server, so that the user can view and manage it at any time.

[0040] Radar 7 can be used to sense the approach or departure of the user, thereby automatically closing the faucet and achieving a more convenient and energy-saving water use experience. Radar 7 can also be used in combination with other water quality monitoring sensors to jointly build a water quality monitoring system. When the water quality is abnormal, radar 7 can cooperate with display module 2 and light-emitting unit to issue a warning signal. For example, when radar 7 senses the approach of a user, the control module 4 controls the display module 2 and the light-emitting unit to issue a warning signal, so that the approaching user will notice the warning signal in time, thereby reminding the user to deal with it in time.

[0041] The water treatment equipment can be connected to the household water inlet and used. Users can easily obtain mineralized and purified drinking water through the water treatment equipment to meet the daily drinking water needs of the family.

[0042] like Figure 2 As shown, in one embodiment, a method for displaying water quality information is provided, and the method for displaying water quality information specifically comprises the following steps: S1: receiving a water outlet instruction, wherein the water outlet instruction carries first water flow speed information; S2: Obtaining a first soluble substance content value upstream of an alkaline filter material and a second soluble substance content value downstream of the alkaline filter material in a water treatment device; S3: Calculate the current soluble substance content difference according to the first soluble substance content value and the second soluble substance content value; S4: Calculate a first current outlet water pH value based on the current soluble substance content difference, and adjust the first water flow rate according to the first current outlet water pH value to obtain water quality information corresponding to the water outlet instruction, wherein the water quality information includes an outlet water pH value, and the outlet water pH value is within a preset target pH value range; S5: Displaying the water quality information through the display interface of the water treatment equipment.

[0043] In the above step S1 of this embodiment, the water treatment device can receive the water outlet instruction in a variety of ways. For example, the water treatment device is equipped with a physical button. When the user presses the button, the button circuit generates an electrical signal, and the electrical signal is received through the interface connected to the button circuit, thereby identifying it as a water outlet instruction. For another example, a water outlet instruction sent from a mobile phone APP or other remote control device is received through a network (such as Wi-Fi, Bluetooth, etc.). The above-mentioned first water flow rate can be a preset fixed water flow rate value or a preset fixed water flow rate interval. It is also possible to select a suitable speed as the first water flow rate within the preset fixed water flow rate interval according to the user's water outlet type requirements.

[0044] In step S2, in the field of water treatment, the soluble substance content value is usually used to measure the total amount of dissolved substances in water, and these dissolved substances may include salts, minerals, organic matter, etc. By detecting the soluble substance 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 substance content value may include the soluble substance content value or the conductivity.

[0045] The total dissolved solids (TDS) value refers to the total amount of solids dissolved in water, including both inorganic and organic matter. The unit of measurement is mg / L (1mg / L=1ppm), 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 sensor is an instrument that reflects the mineralization degree of water quality by measuring the conductivity of water.

[0046] Conductivity is a measure of the concentration of ions in water, and it 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, and it 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.

[0047] The detector can be installed at appropriate locations in the water treatment equipment, e.g. Figure 3 As shown, a first detector 51 is installed at the upstream position of the alkaline filter material 31 of the water treatment equipment to detect the soluble substance content value (i.e., the first soluble substance content value) upstream of the alkaline filter material 31 in real time. The first soluble substance content value is the soluble substance content value before the water flows through the alkaline filter material 31, that is, the soluble substance content value of the raw water. Similarly, a second detector 52 is installed at the downstream position of the alkaline filter material 31 of the water treatment equipment to detect the soluble substance content value (i.e., the second soluble substance content value) downstream of the alkaline filter material 31 in real time. The second soluble substance content value is the soluble substance content value after the water flows through the alkaline filter material 31.

[0048] In the above step S3, in order to obtain the soluble substance content difference, the first soluble substance content value may be subtracted from the second soluble substance content value.

[0049] like Figure 3 As shown, assuming that the first detector 51 is a first TDS sensor, the first TDS sensor detects the first soluble substance content value upstream of the alkaline filter material as TDS1, and the second detector 52 is a second TDS sensor, the second TDS sensor detects the second soluble substance content value downstream of the alkaline filter material as TDS2, then the soluble substance content difference It can be expressed as: .

[0050] Assuming that the first detector 51 is a first conductivity sensor, the first conductivity sensor detects a first soluble substance content value upstream of the alkaline filter material as conductivity 1, and the second detector 52 is a second conductivity sensor, and the second conductivity sensor detects a second soluble substance content value downstream of the alkaline filter material as conductivity 2, then the difference in soluble substance content (Δconductivity) can be expressed as: Δconductivity=conductivity2-conductivity1.

[0051] The difference in dissolved matter content indicates the change in dissolved matter content in water during the treatment process and can be used to evaluate the performance of water treatment equipment or monitor changes in water quality.

[0052] It should be understood that in water treatment equipment with mineral spring function, the difference in dissolved matter content is usually not less than 0. The reason is that water treatment equipment reintegrates the mineral elements needed by the human body into the water by adding mineral-rich filter materials (such as calcium, magnesium, zinc and other ores). These minerals exist in the water in ions or dissolved states. This process will increase the content of dissolved substances in the water. Even if purification is carried out before mineralization to remove harmful substances and impurities in the water, this part of the reduction is mainly non-mineral dissolved solids. The minerals added in the mineralization process will compensate for or even exceed this reduction, causing the overall dissolved matter content value to increase.

[0053] In the above step S4, in order to obtain the pH value of the effluent, in a specific embodiment, mapping can be performed according to a pre-set mapping relationship between the soluble substance content difference and the effluent pH value. The effluent pH values ​​corresponding to different soluble substance content differences measured by a large number of experiments are collected in advance, and then these data are fitted to establish a mapping relationship between the soluble substance content difference and the effluent pH value. The mapping relationship can be in a tabular form or a functional relationship. For example, the soluble substance content difference, such as Linear fitting with pH value gives the relationship: . Among them, a is the source term constant, and b is the amplitude index, both of which are related to the alkaline performance of the alkaline filter material and are measured experimentally. According to the current soluble substance content difference, the corresponding effluent pH value is found in the preset mapping relationship. For the mapping relationship in tabular form, by traversing the table, find the record closest to the current soluble substance content difference, and obtain the corresponding effluent pH value as the first current effluent pH value; for the mapping relationship of the functional relationship, substitute the current soluble substance content difference into the function for calculation to obtain the effluent pH value. According to the preset mapping relationship, the effluent pH value is inferred by the measured and calculated soluble substance content difference, which avoids the addition of expensive pH meters and reduces the cost of water quality monitoring.

[0054] In some embodiments, a preset soluble substance content difference threshold is set in the water treatment equipment. When the measured soluble substance content difference is not within the preset soluble substance content difference threshold range, information about insufficient soluble substance content is generated, and the user is notified through the local display of the water treatment equipment and / or APP reminder that the minerals in the alkaline filter material have been consumed and the alkaline filter material needs to be replaced.

[0055] The water treatment equipment stores a preset target pH range, such as 6.5 to 8.5, or 7.5 to 8.5, and the user can flexibly adjust it according to specific usage requirements. When it is determined that the first current water outlet pH value is not within the preset target pH range, it is necessary to send different control signals to the water flow control device to adjust the water flow rate according to the specific situation. The water flow control device adjusts the water pump speed or the solenoid valve opening accordingly according to the signal sent by the terminal to adjust the water flow rate. By adjusting the water flow rate, the dissolution amount of mineral ions in the water treatment equipment is adjusted, so that the pH value of the water outlet gradually approaches the preset target pH range, so that the water treatment equipment whose water outlet does not meet the target pH range requirements can still output water within the preset target pH range.

[0056] In the above step S5, the display interface display method for the soluble substance content information includes a mineral ring preset on the display interface of the water treatment equipment. When the above soluble substance content difference is not within the soluble substance content difference threshold, the color of the mineral ring is adjusted to a preset warning color, such as red; or the mineral ring is flashed at a preset frequency; or the mineral ring is not lit to prompt the user, etc.

[0057] There are many ways to display the pH value interface. For example, in some embodiments, a vertical light bar can be used to display the pH. From bottom to top, the pH gradually increases from 6.5 to 8.5. The light bar is gradually filled according to the received pH value of the water outlet until the corresponding pH value position is reached. When the pH value is lower or higher than the set value of the light bar, the light bar is set to flash red as a whole, and an APP or the like prompts that it is too high or too low. In other embodiments, an LCD screen can be used for display; an indicator light can also be used for display, and different pH value intervals correspond to different colored indicator lights. The color combination of the indicator lights indicates that the current pH value is within the target pH value range, etc.

[0058] Optionally, the display interface of the water treatment equipment can also display, for example, a signal / value display area for presenting signals such as the remaining life of the alkaline filter material, the networking status of the water treatment equipment, and values ​​such as water output and fault codes.

[0059] Optionally, a water volume selection area can also be displayed on the display interface of the water treatment equipment. The user can click to select the required water output. Different water outputs correspond to different numbers of clicks, or different water outputs correspond to different symbols, and the selected water output size is presented in the numerical display area.

[0060] The present application calculates different water quality information through the difference in soluble substance content, avoiding the use of multiple water quality detection equipment, thereby saving the cost of using water treatment equipment; and then compares the first current water outlet pH value with the preset target pH value range, and adjusts to a suitable water flow rate according to the comparison result, so as to adjust the dissolution amount of mineral ions in the water treatment equipment through the water flow rate, so that the pH value of the water outlet gradually approaches the preset target pH value range, so that the water treatment equipment whose water outlet does not meet the requirements of the target pH value range can still output water within the preset target pH value range, thereby extending the service life of the alkaline filter material in the water treatment equipment and giving full play to the use potential of the alkaline filter material.

[0061] In some optional embodiments, the step S4 of calculating the first current outlet water pH value based on the current soluble substance content difference, adjusting the first water flow rate according to the first current outlet water pH value, obtaining the water quality information corresponding to the outlet water instruction, and the outlet water pH value being within the preset target pH value range includes: S41: Obtaining a first current outlet water pH value corresponding to the current soluble substance content difference according to a preset soluble substance content difference-outlet water pH value mapping relationship; S42: comparing the first current outlet water pH value with a preset target pH value range; S43: when the first current outlet water pH value is within the preset target pH value range, using the first current outlet water pH value as the outlet water pH value in the water quality information; S44: When the first current outlet water pH value is not within the preset target pH value range, controlling the water treatment device to outlet water at a second water flow rate, wherein the second water flow rate is not equal to the first water flow rate; S45: Detecting a second current pH value of the outlet water at the second water flow rate, and using the second current pH value of the outlet water as the outlet water pH value in the water quality information.

[0062] In the above step S41 of the present embodiment, the above first current outlet water pH value can be obtained by mapping according to a preset mapping relationship of soluble substance content difference-outlet water pH value. The method for establishing the mapping relationship of soluble substance content difference-outlet water pH value is the same as the previous step S4, and this embodiment will not be repeated here. According to the current soluble substance content difference, the corresponding outlet water pH value is searched in the preset mapping relationship as the above first current outlet water pH value. For the mapping relationship in the form of a table, by traversing the table, find the record closest to the current soluble substance content difference, and obtain the corresponding outlet water pH value as the first current outlet water pH value; for the mapping relationship of the functional relationship, substitute the current soluble substance content difference into the function for calculation to obtain the first current outlet water pH value.

[0063] In the above step S42, after obtaining the first current water outlet pH value, the first current water outlet pH value is compared with the lower limit value and the upper limit value of the preset target pH value range. If the first current water outlet pH value is greater than or equal to the lower limit value and less than or equal to the upper limit value, it is determined to be within the target pH value range; otherwise, it is determined not to be within the target pH value range.

[0064] In the above step S43, when it is determined that the first current water outlet pH value is within the preset target pH value range, a control signal will be sent to the water flow control device (such as a water pump, a solenoid valve, etc.) of the water treatment equipment to control it to adjust the water flow rate to the first water flow rate (for example, by adjusting the speed of the water pump or the opening of the solenoid valve to achieve water outlet at the first water flow rate), and directly use the first current water outlet pH as the water outlet pH value for display on the display interface of the water treatment equipment.

[0065] In the above step S44, when it is determined that the first current water outlet pH value is not within the preset target pH value range, it is necessary to send different control signals to the water flow control device according to the specific situation to adjust the water flow rate. Specifically, if the first current water outlet pH value is higher than the upper limit of the target pH value range, it means that the mineral ion concentration in the water is too high. At this time, the second water flow rate can be set to be faster than the first water flow rate to speed up the flow of water, reduce the contact time between the alkaline filter material and water, and reduce the dissolution amount of mineral ions. On the contrary, if the first current water outlet pH value is lower than the lower limit of the target pH value range, it means that the mineral ion concentration in the water is too low. At this time, the second water flow rate can be set to be slower than the first water flow rate to increase the contact time between the alkaline filter material and water and increase the dissolution amount of mineral ions. The water flow control device adjusts the water pump speed or the solenoid valve opening accordingly according to the signal sent by the terminal to achieve water outlet at the second water flow rate.

[0066] In the above step S45, after adjusting the water outlet speed to a suitable second water flow speed, the dissolution amount and dissolution rate of mineral ions in the water outlet from the water treatment equipment also change accordingly, that is, the second soluble substance content value changes, thereby causing the soluble substance content difference to change, and then the second current water outlet pH value also changes accordingly. The specific second current water outlet pH value can be calculated by the method of calculating the pH value by the soluble substance content difference as described above.

[0067] This embodiment selects a suitable second water flow rate so that the water treatment equipment whose outlet water does not meet the target pH value range requirements can still output water within the preset target pH value range, and uses the re-detected second current outlet water pH value as the outlet water pH value for display on the display interface, thereby extending the service life of the alkaline filter material in the water treatment equipment. Through in-depth analysis of the difference in the content of soluble substances, users are provided with interrelated and diverse water quality information, which is conducive to a more comprehensive judgment of the use of the alkaline filter material, so as to give full play to the use potential of the alkaline filter material.

[0068] In some optional embodiments, when the first current outlet water pH value is not within the preset target pH value range, the step S44 of controlling the water treatment equipment to discharge water at a second water flow rate, wherein the second water flow rate is not equal to the first water flow rate, comprises: S441: When the first current outlet water pH value is higher than the preset target pH value range, calculating a first current pH difference between the first current outlet water pH value and an upper limit of the preset target pH value range; S442: Obtaining a first adjusted flow rate corresponding to the first current pH difference according to a preset pH difference-adjusted flow rate mapping relationship; S443: taking the sum of the first water flow rate and the first adjusted flow rate as the second water flow rate, and controlling the water treatment equipment to discharge water at the second water flow rate.

[0069] In step S441 of this embodiment, after receiving the first current water outlet pH value, it is compared with the upper limit of the preset target pH value range. If the first current water outlet pH value is greater than the upper limit, it can be determined that the first current water outlet pH value is higher than the preset target pH value range.

[0070] In the above step S442, in order to obtain the pH difference-adjusted flow rate mapping relationship, it is necessary to conduct a large number of experiments in advance to measure the flow rate required to adjust the outlet pH value to fall within the target range under different pH differences, and organize these data into a pH difference-adjusted flow rate mapping relationship. The mapping relationship can be in a tabular form or a function relationship obtained by fitting.

[0071] After calculating the first current pH difference, search for the corresponding first adjusted flow rate in the preset mapping relationship according to the first current pH difference. For a mapping relationship in the form of a table, traverse the table to find the record closest to the first current pH difference, and obtain the corresponding adjusted flow rate as the first adjusted flow rate; for a functional relationship, substitute the first current pH difference into the function for calculation to obtain the first adjusted flow rate corresponding to the first current pH difference. By using the preset mapping relationship and determining the first adjusted flow rate according to the first current pH difference, it is possible to accurately adjust the water flow rate according to the specific degree to which the pH value deviates from the target range, thereby improving the effectiveness of the water flow rate adjustment.

[0072] In the above step S443, after obtaining the first water flow velocity and the first adjusted flow velocity, an addition operation is performed to obtain the second water flow velocity, and a control signal corresponding to the calculated second water flow velocity is sent to a water flow control device (such as a water pump or a solenoid valve). After receiving the signal, the water flow control device adjusts its own working parameters (such as a water pump adjusting the motor speed, and a solenoid valve adjusting the valve opening) to make the water flow velocity reach the second water flow velocity and discharge water.

[0073] In this embodiment, when the first current water outlet pH value is too high, the second water flow rate is obtained by adding the first water flow rate to the first adjustment flow rate, and the water flow rate can be dynamically adjusted according to the degree to which the first current water outlet pH value is higher than the target range. Increasing the water flow rate can reduce the contact time between water and alkaline filter materials, reduce the amount of mineral ion dissolution, and make the water outlet pH value fall into the preset target pH value range, effectively improving water quality and enhancing user experience.

[0074] In other optional embodiments, when the first current water outlet pH value is too high, the specific numerical value of the first adjusted flow rate can be a preset fixed value; it can also be determined according to a preset rule, for example, the second water flow rate is a preset multiple (greater than 1) of the first water flow rate, such as 1.5 times, 2 times, etc.

[0075] In some optional embodiments, when the first current outlet water pH value is not within the preset target pH value range, the step S44 of controlling the water treatment equipment to discharge water at a second water flow rate, wherein the second water flow rate is not equal to the first water flow rate, comprises: S444: When the first current outlet water pH value is lower than the preset target pH value range, calculating a second current pH difference between the first current outlet water pH value and a lower limit of the preset target pH value range; S445: Obtaining a second adjusted flow rate corresponding to the second current pH difference according to a preset pH difference-adjusted flow rate mapping relationship; S446: Taking the difference between the first water flow rate and the second adjusted flow rate as the second water flow rate, and controlling the water treatment equipment to discharge water at the second water flow rate.

[0076] In the above step S444 of this embodiment, after receiving the first current outlet water pH value, the second current pH difference is calculated by the following calculation formula: second current pH difference = lower limit of the preset target pH value range - first current outlet water pH value.

[0077] In the above step S445, similar to the above step S442, a pH difference-adjusted flow rate mapping relationship is established, and the second adjusted flow rate corresponding to the second current pH difference is obtained according to the mapping relationship. The specific process is not repeated in this embodiment.

[0078] In the above step S446, after obtaining the first water flow rate and the second adjusted flow rate, the second water flow rate is calculated by the second water flow rate = first water flow rate - second adjusted flow rate. The control signal corresponding to the calculated second water flow rate is sent to the water flow control device (such as a water pump or a solenoid valve). After receiving the signal, the water flow control device adjusts its own working parameters to achieve water discharge at the second water flow rate. For the water pump, reduce the motor speed; for the solenoid valve, reduce the valve opening.

[0079] In this embodiment, when the first current water outlet pH value is too low, the second water flow rate is obtained by subtracting the second adjusted flow rate from the first water flow rate, which can reduce the water flow rate and increase the contact time between water and alkaline filter material, so that the alkaline filter material has more time to release mineral ions into the water, thereby increasing the pH value of the water outlet to fall within the preset target pH value range, effectively improving the water quality and enhancing the user experience.

[0080] In other optional embodiments, when the first current water outlet pH value is too low, the specific value of the second adjusted flow rate can be a preset fixed value; it can also be determined according to a preset rule, for example, the second water flow rate is a preset multiple (less than 1) of the first water flow rate, such as 0.5 times, 0.7 times, etc.

[0081] In some optional embodiments, the step S45 of detecting the second current outlet water pH value at the second water flow rate and using the second current outlet water pH value as the outlet water pH value in the water quality information includes: S451: After a first preset time from the start of water discharge, real-time detection of a second current water discharge pH value at the second water flow rate; S452: Determine whether the second current outlet water pH value is within the preset target pH value range; S453: If the second current outlet water pH value is within the preset target pH value range, the second current outlet water pH value is displayed on the water treatment device in a preset display manner.

[0082] In the above step S451 of this embodiment, when the water treatment equipment starts to discharge water at the second water flow rate, the timing module is started at the same time. The timing module can be a hardware-based timer or a timing function in a software program. When the timing value reaches a first preset time (the first preset time can be pre-set based on experiments or experience, such as 10 seconds), the operation of calculating the second current water outlet pH value is triggered. The calculation of the second current water outlet pH value can be calculated using a method similar to that of obtaining the first current water outlet pH value, which will not be repeated in this embodiment.

[0083] After changing the water flow rate, when the water flow rate just starts to change, the concentration distribution of dissolved substances in the water and the rate of related chemical reactions will be affected. For example, the treatment effect of alkaline filter materials on water may change due to the change of water flow rate, and the content of dissolved substances in the water will also change accordingly, and these changes will eventually affect the pH value of the effluent water. These changes take a certain amount of time to stabilize.

[0084] Specifically, when the water flow rate increases or decreases, the soluble substances in the water need a certain amount of time to redistribute and reach a new dissolution equilibrium. In this process, the difference in the content of soluble substances will gradually change and tend to stabilize, and then the pH value of the effluent will gradually stabilize. In the early stage when the water flow rate has just changed, the pH value detected at this time may not be accurate because the change in the total dissolved solids content has not yet reached equilibrium. After the first preset period of time, the water flow state, dissolution and distribution of soluble substances in the water treatment equipment basically reach a new equilibrium. At this time, the second current effluent pH value detected is more accurate and can more truly reflect the actual pH value of the effluent from the water treatment equipment at the new water flow rate.

[0085] In the above step S452, after obtaining the second current water outlet pH value, it is compared with the lower limit value and the upper limit value of the preset target pH value range. If the second current water outlet pH value is greater than or equal to the lower limit value and less than or equal to the upper limit value, it is determined to be within the preset target pH value range; otherwise, it is determined not to be within the target pH value range.

[0086] In the above step S453, when it is determined that the second current outlet water pH value is within the preset target pH value range, the display control program is called to display the second current outlet water pH value.

[0087] Normally, through the above adjustment, the pH of the outlet water can be adjusted to the preset target pH range. If the pH of the outlet water still does not reach the preset target pH range under special circumstances, the second water flow rate can be further increased to the preset maximum water flow rate to quickly reduce the pH of the outlet water so that it reaches the user's ideal target pH range, thereby improving the user experience.

[0088] In the early stage of the new water treatment equipment being put into use, it is possible that the alkaline filter material will release a large amount of mineral ions into the water in a short period of time due to its abundant surface active sites and strong ion exchange capacity when it is first put into use, causing the pH value of the effluent to exceed the upper limit of the target pH value range. At this time, by speeding up the water flow rate, the initial effluent pH value can be reduced to a certain extent, so as to reach the user's ideal target pH value range, avoid directly displaying too high a pH value, which may cause the user to discard a large amount of effluent in the early stage, and is conducive to maximizing the use potential of the alkaline filter material.

[0089] As the alkaline filter material is used for a longer time and approaches its service life cycle, the number of ion exchange active sites inside the filter material decreases, and its ability to release soluble substances decreases significantly, and the pH value may be lower than the lower limit of the target pH range. At this time, the pH value can be increased to a certain extent by reducing the water flow rate, so that it is still within the target pH range acceptable to the user, extending the service life of the alkaline filter material and giving full play to the potential of the alkaline filter material. While continuing to use the alkaline filter material in this way, it is necessary to promptly send a reminder to the user through a preset reminder method that the filter material needs to be replaced, informing the user that the alkaline filter material is approaching its service life and needs to be replaced in time, giving the user sufficient time to prepare a new alkaline filter material, and still providing the user with water within the target pH range during the user's preparation period. The preset reminder method can be a sound reminder, playing a specific prompt tone or voice message through the built-in speaker, such as "alkaline filter material needs to be replaced"; it can also be a light reminder, such as flashing a specific color indicator light on the device; it can also be a reminder message pushed through a mobile phone APP bound to the device, so that the user can receive a notification of replacing the alkaline filter material on the mobile phone in time.

[0090] In some embodiments, the water quality information further includes soluble substance content information, and before the step S4 of displaying the water quality information through the display interface of the water treatment device, the step further includes: S461: Determine whether the current soluble substance content difference is within a preset soluble substance content difference threshold range; S462: If yes, then generate water quality information indicating that the content of dissolved substances meets the standard.

[0091] In this embodiment, if the current soluble substance content difference is within the preset soluble substance content difference threshold range, water quality information that the soluble substance content meets the standard is generated. The water quality information that the soluble substance content meets the standard can be displayed on the display interface in the following manner. For example, when the user takes water, the mineral ring set on the display interface is lit to present it to the user. If the current soluble substance content difference is lower than the preset soluble substance content difference threshold range, water quality information that the soluble substance content does not meet the standard is generated, the mineral ring is not lit, and the user is notified through the APP or other methods that the minerals in the alkaline filter material have been consumed. If the current soluble substance content difference is higher than the preset soluble substance content difference threshold range, the mineral ring is displayed in red, and the user is notified through the APP or other methods that the minerals in the alkaline filter material exceed the standard.

[0092] In some specific embodiments, the water quality information also includes soluble substance content information, and the water output instruction also carries water output information; before the step S4 of displaying the water quality information through the display interface of the water treatment device, the method includes: S463: Based on the current soluble substance content difference, calculate the content of a preset type of mineral in the water output corresponding to the water volume information, and generate first water quality information, wherein the first water quality information includes information on the content of the preset type of mineral; S464: Identify whether the water outlet instruction comes from a designated user; S465: If yes, then obtain the daily drinking water data of the designated user, wherein the daily drinking water data includes the cumulative amount of drinking water consumed by the designated user on the day and the cumulative content of the preset types of minerals; S466: Accumulate the content of the preset mineral types in the first water quality information to the cumulative content of the preset mineral types in the drinking water data of the day, and add the water output to the cumulative drinking water intake of the day, to obtain the updated drinking water data of the designated user on the day, and use the updated drinking water data of the day as the second water quality information; S467: Generate the water quality information corresponding to the water outlet instruction, where the water quality information includes the first water quality information and / or the second water quality information.

[0093] In step S463 of this embodiment, the above-mentioned preset types of minerals include, for example, calcium, magnesium, strontium, metasilicic acid, potassium, sodium, etc., and the corresponding contents of various preset types of minerals are searched according to the mapping relationship between the preset soluble substance content difference and the preset type of mineral content. Combined with the water output information carried in the water output instruction, the specific content of each preset type of mineral in the water output can be calculated. The above-mentioned first water quality information includes information on the content of preset types of minerals, and the content of each preset type of mineral in the first water quality information can be displayed in the display interface in the form of numbers or the like.

[0094] In the above step S464, when a water discharge instruction is received, a user identification device (such as face recognition, fingerprint recognition, etc.) provided on the water treatment device can be used to determine whether the water discharge instruction comes from a designated user. If the water discharge instruction is sent via a mobile terminal, it can be determined whether the water discharge instruction comes from a designated user by comparing the user ID.

[0095] In the above steps S465-S466, independent drinking water data records are established for each designated user, and these records are stored in the database, with the user ID of the designated user as the index. The daily drinking water data will be updated in real time with each drinking operation of the user, and can reflect the changes in the drinking water and mineral intake of the designated user in real time, providing users with more accurate personalized water quality information, and helping users to reasonably control mineral intake and water drinking. When the designated user takes water, the above second water quality information is displayed through the display interface. In some other embodiments, the second water quality information can also be displayed in the user APP of the designated user.

[0096] In the above step S467, water quality information is generated according to different situations, and appropriate water quality information services can be provided for different types of users. For ordinary users, first water quality information including mineral content information of the output water is provided; for designated users, second water quality information including personalized daily water intake and mineral intake information is further provided to meet the needs of different users.
