BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic diagram of an intelligent bubble concentration control system for a sparkling water machine provided in the first embodiment of the present application. DETAILED DESCRIPTION

[0024] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0025] The first embodiment of the present application provides an intelligent bubble concentration control system for a sparkling water machine. Figure 1 , which is a schematic diagram of the first embodiment of the present application. Figure 1 A first embodiment of the present application provides a system for controlling the intelligent bubble concentration of a sparkling water machine, which is described in detail.

[0026] The intelligent bubble concentration control system of the sparkling water machine includes a gas injection module 101, a water temperature control module 102, a concentration sensing module 103, a pressure control module 104, a control processing unit 105, a user interaction unit 106, a communication module 107 and a bubble retention time evaluation module 108.

[0027] The gas injection module 101 is used to inject gas into water at an adjustable flow rate according to a set bubble concentration target.

[0028] The gas injection module 101 is one of the core components of the control system provided in this embodiment, and is used to inject gas into water in a precisely controllable manner to achieve the generation of a target bubble concentration. The module includes a gas supply unit, a flow regulating unit, an injection nozzle or a diffuser, and an interface for communicating with the control processing unit 105.

[0029] The gas injection module 101 obtains gas through a gas supply unit, and the gas can be food-grade gas such as carbon dioxide, nitrogen or oxygen, and the specific selection can be determined according to the target application and user needs. The gas supply unit can use a high-pressure gas tank or be directly connected to a gas generating device (such as a carbon dioxide generator), and the gas pressure is controlled within a certain range through a pressure regulating valve to ensure the stability of the input gas flow.

[0030] In high-end applications, the gas supply unit can be equipped with a gas composition sensor to monitor the gas purity in real time to ensure that the injected gas meets safety standards. If it is detected that the gas purity does not meet the requirements, the module will send an alarm signal to the control processing unit to prevent further operation.

[0031] The flow regulating unit is a key component for achieving precise bubble concentration control in the gas injection module 101. The unit is usually composed of an electronically controlled proportional valve or a mass flow controller (MFC), and adjusts the injection flow of the gas in real time through an electronic control signal.

[0032] The flow regulating unit receives the flow parameters calculated by the control processing unit and dynamically adjusts the flow size according to the concentration deviation value. For example, when the concentration sensor module 103 feedbacks that the bubble concentration is lower than the target concentration, the control processing unit increases the gas flow through the flow regulating unit, and vice versa. The response time of flow regulation is usually controlled at the millisecond level to ensure the real-time and stability of the bubble water generation process.

[0033] In order to further improve the accuracy, the flow regulation unit can be equipped with a closed-loop control circuit, combined with an internal flow sensor to perform secondary detection of the actual gas flow, and adjust the valve opening through feedback to avoid concentration deviation caused by system errors.

[0034] The injection nozzle or diffuser is the key interface between the gas injection module and water. Its function is to inject gas into water and achieve sufficient mixing. The design of the nozzle directly affects the bubble size, distribution and stability, so it needs to be optimized according to the principles of fluid mechanics.

[0035] The nozzle can adopt a microporous diffusion design to evenly diffuse the gas into the water in the form of tiny bubbles through multiple tiny apertures. This design can significantly increase the contact area between the gas and water, thereby improving the stability and dissolution efficiency of the bubbles. In certain cases, a guide plate can be set around the diffuser to form a vortex structure to further optimize the uniformity of bubble distribution.

[0036] In addition, in order to meet different concentration requirements, the nozzle can be designed with an adjustable aperture structure. The user can select different nozzle modes, such as "high concentration microbubble mode" or "low concentration large bubble mode" through the user interaction unit 106 to meet different drinking preferences.

[0037] The gas injection module is connected to the control processing unit 105 via a communication interface to achieve data exchange and command reception. The interface usually uses a digital signal communication method, such as I 2 C or CAN bus to ensure high-speed and stable data transmission.

[0038] The communication interface is used to receive the target flow parameters sent by the control processing unit, and to provide real-time feedback on the flow regulating unit and gas injection status, including information such as actual flow, gas pressure, and nozzle opening status. This information is used by the control processing unit to dynamically adjust the operating parameters of other modules (such as the water temperature control module 102 and the pressure control module 104), forming a closed-loop system of multi-parameter linkage control.

[0039] When the user sets the target bubble concentration through the user interaction unit, the control processing unit sends instructions to the flow regulating unit of the gas injection module according to the difference between the set value and the real-time concentration. The flow regulating unit adjusts the valve opening to inject the gas into the nozzle at the set flow rate. At the same time, the pressure control module 104 detects and maintains the gas pressure in the optimal range to ensure the stability of the gas flow rate and diffusion effect at the nozzle. Finally, the gas is evenly injected into the water through the nozzle, and the concentration sensor module 103 detects the generated bubble concentration in real time to form a closed-loop control.

[0040] Through the above-mentioned structural and functional design, the gas injection module 101 can achieve high-precision and high-stability bubble generation, ensuring that the system can meet the performance requirements in a variety of usage scenarios, while significantly improving user experience and equipment reliability.

[0041] The water temperature control module 102 is connected to the gas injection module and is used to monitor the water temperature in real time and adjust the water temperature according to the bubble concentration requirement to optimize the distribution and stability of the bubbles.

[0042] The water temperature control module 102 is an important part of the system. Its main function is to monitor and adjust the water temperature in real time to ensure that the water temperature can meet the requirements of uniformity and stability of bubble distribution during the process of bubble generation and dissolution. Water temperature plays a key role in the generation of bubble water, because the formation, particle size stability and retention time of bubbles are directly affected by water temperature. The water temperature control module works in coordination with the gas injection module 101 to effectively improve the quality of bubble water while optimizing the bubble concentration.

[0043] The water temperature control module 102 includes a water temperature sensor, a heating unit, a cooling unit and a control interface. The water temperature sensor is used to monitor the current water temperature in real time and transmit the measurement signal to the control processing unit 105. In order to ensure the accuracy of water temperature control, the water temperature sensor can use a highly sensitive semiconductor sensor or a thermistor, which can capture water temperature changes with a millisecond response time. This real-time water temperature feedback ensures that the module can respond quickly to water temperature fluctuations and avoid uneven bubble distribution or unstable bubbles due to excessive temperature changes.

[0044] The heating unit usually adopts a resistive heater, a thin film heater or an immersion heating rod, and its adjustable power range is dynamically set according to the water volume and target temperature requirements. For example, when the water temperature is detected to be lower than the preset range, the heating unit starts quickly and heats the water temperature to the target value through precise power output. In the case of cooling, the cooling unit can adopt a thermoelectric cooling component or a cooling plate with a cooling circuit to ensure that the water temperature is controlled within the set range by rapid cooling. The role of the cooling unit is particularly important. In summer environments or high-frequency use, the cooling function can effectively prevent the negative impact of excessive water temperature on the quality of sparkling water.

[0045] The water temperature control module communicates with the control processing unit through a digital signal interface. The control processing unit dynamically adjusts the water temperature parameters according to the real-time concentration signal provided by the concentration sensor module 103 and the bubble concentration requirement preset by the user. For example, when the bubble concentration requirement is high, the system will preferentially adjust the water temperature to the temperature range for optimal bubble distribution (e.g., 4°C to 10°C) to enhance the stability of the bubbles in the water and prolong their residence time. In low concentration mode, the water temperature may be set within a higher range to meet the user's needs for different bubble sensory experiences.

[0046] In order to further optimize the performance of the water temperature control module, a closed-loop control algorithm can be designed inside the module, which combines PID (proportional-integral-differential) control or fuzzy logic control to dynamically adjust the output of the heating and cooling units. This closed-loop control method can quickly correct water temperature deviations when the external ambient temperature changes or the water volume changes, ensuring that the output water temperature is always stable within the target range. In addition, the module can also optimize future water temperature control strategies by storing historical temperature data and combining data from the concentration sensor module and the bubble retention time evaluation module to improve the overall efficiency of the system and user experience.

[0047] In order to meet the diverse usage scenarios, the water temperature control module can also be equipped with an adaptive mode. In this mode, the module will automatically adjust the water temperature control range and response speed according to the user's usage habits and actual environmental conditions. For example, when the system detects that the ambient temperature is low, the adaptive mode will give priority to increasing the response speed of the heating unit, and enhance the cooling capacity of the cooling unit in a high temperature environment.

[0048] To facilitate user maintenance, the water temperature control module can also be designed with cleaning and self-checking functions. During long-term use, minerals in the water may form deposits on the heating or cooling unit, thus affecting the performance of the module. With the built-in cleaning mode, the system can automatically clean the heating and cooling units regularly to extend the service life of the module and ensure the control accuracy. In addition, the self-checking function can monitor the operating status of the module in real time, and send an alarm to the user or automatically adjust the operating parameters when abnormal conditions are detected to ensure the safety and stability of the system.

[0049] In summary, the water temperature control module 102 in this system is not just a simple water temperature adjustment device, but a key module integrating real-time monitoring, high-precision control, multi-scenario adaptation and intelligent optimization. Its design ensures that the system can provide the optimal water temperature conditions during the bubble generation process, greatly improving the distribution uniformity, particle size stability and retention time of bubbles, significantly improving the user's drinking experience, and providing strong support for the overall intelligence of the system.

[0050] The concentration sensor module 103 is disposed in the water flow channel and is used to detect the real-time bubble concentration of the generated bubble water and generate a concentration signal.

[0051] The concentration sensor module 103 is one of the core components of the system. Its function is to detect the bubble concentration of the generated bubble water in real time and transmit this concentration value to the control processing unit 105 in the form of a signal, providing key data support for subsequent dynamic adjustment and closed-loop control. The design of the concentration sensor module is based on the combination of fluid mechanics and optical detection technology, ensuring that it can monitor the distribution and concentration of bubbles in water with high precision and high responsiveness, meeting the requirements of intelligent control.

[0052] The module is mainly composed of an optical detection unit, a data processing unit, a signal output unit, and a special sensing structure installed in the water flow channel. The optical detection unit is its core component, which is usually composed of a laser transmitter and a photoelectric receiver. The laser transmitter passes a laser beam of a specific wavelength through the bubbling water, and the receiver collects a signal containing information about the bubble concentration based on the scattering, absorption, and reflection changes of the beam in the water. In order to improve the detection accuracy and scope of application, multi-wavelength lasers can be used, combined with the differential absorption characteristics of bubbles and water at different wavelengths, so as to accurately distinguish subtle changes in bubble particle size and concentration.

[0053] The optical detection unit needs to form a stable optical path structure inside the module, and is usually equipped with waterproof protection devices and anti-reflective coatings to ensure long-term reliability. At the same time, in order to avoid the interference of impurities or irregular movement of bubbles in the water flow on the detection results, the sensor module can be designed to form a flow stability zone in the water flow channel. This stable zone is usually achieved by setting rectifiers or turbulence buffers before and after the sensing area to ensure that the flow velocity of the water in the sensing area is constant and the bubbles are evenly distributed, thereby improving the accuracy of detection.

[0054] The data processing unit collects and analyzes the signals from the photoelectric receiver in real time, and uses an embedded processor or FPGA hardware accelerator to filter, amplify and normalize the signals. Through the built-in algorithm, the module can extract characteristic parameters that characterize the bubble concentration from the collected signal, such as optical scattering intensity, signal periodicity and spectrum distribution. In order to improve robustness, the algorithm can be combined with machine learning technology and trained with multiple groups of bubble water samples before the module leaves the factory to automatically adapt to complex detection environments under different water quality, gas type and temperature conditions.

[0055] The signal output unit is responsible for transmitting the processed concentration information in the form of digital signals or analog signals to the control processing unit 105. To ensure the stability and real-time performance of communication, the concentration sensor module supports mainstream communication protocols, such as I 2 C, SPI or RS485, and can be designed as a wireless communication method according to needs, such as Bluetooth or Wi-Fi, to facilitate flexible layout and remote monitoring of modules. Signal output can include real-time concentration value, bubble distribution information and equipment operation status, such as light path contamination alarm or sensor failure reminder.

[0056] The installation position of the concentration sensor module is also very critical in the design of the system. It is usually located in the area after the gas and water are fully mixed in the water flow channel. This position ensures that the sensor module monitors the most representative bubble concentration while avoiding detection deviations caused by incomplete formation or excessive decomposition of bubbles. The physical installation method of the module usually adopts a snap-on, embedded or flange connection, combined with a sealing structure to ensure the stability and safety of the module when operating under high pressure or high flow rate conditions.

[0057] The concentration sensing module can be combined with other types of sensing technologies, such as acoustic sensing technology or electrochemical sensing technology, to form a multimodal detection structure. Acoustic sensing technology uses the attenuation and reflection characteristics of ultrasonic waves when propagating in bubble water, which can complement optical detection technology and improve the detection ability of high-concentration bubble water. Electrochemical sensing technology is suitable for detecting changes in the solubility of specific gas components in water, thereby further improving the applicability and detection range of the system.

[0058] In order to meet the personalized needs of different users for bubble concentration, the concentration sensor module can also preset multiple detection sensitivity modes, such as a high sensitivity mode for accurate detection of small bubbles and a low sensitivity mode for rapid detection of large bubbles. These modes can be selected through the user interaction unit 106, or automatically switched by the control processing unit according to the system operation status.

[0059] In summary, the concentration sensing module 103 in this system significantly improves the accuracy and real-time performance of bubble concentration detection through highly integrated optical detection, precise signal processing, diversified communication methods and flexible installation design, providing a solid technical foundation for realizing intelligent bubble concentration control.

[0060] The pressure regulating module 104 is disposed in the gas supply path of the gas injection module and is used to detect and adjust the pressure of the gas injection to maintain a stable bubble particle size and distribution during the bubble generation process.

[0061] The pressure control module 104 is a key component in the system to ensure the stability and consistency of the bubble generation process. The main function of this module is to perform real-time pressure detection and regulation on the gas supply path of the gas injection module to control the pressure level when the gas enters the water flow, thereby optimizing the bubble size, distribution and dissolution efficiency. The precise control of gas pressure not only affects the uniformity of bubble generation, but also directly determines the stability of the bubble and its residence time in water.

[0062] The pressure control module consists of a pressure sensor, a pressure regulating valve, a signal processing unit and a control interface. The pressure sensor is installed at a key position in the gas supply path to monitor the pressure changes of the gas in real time. The sensor usually adopts a high-precision piezoelectric or strain gauge design, which can provide a fast response and generate an electrical signal proportional to the pressure value under high pressure. In order to enhance its adaptability, the working range of the sensor can cover a variety of gas pressure conditions, from low pressure (such as several kilopascals) to high pressure (such as several megapascals), ensuring that the equipment can work efficiently under different gas types and usage environments.

[0063] The pressure regulating valve is a pressure-controlled actuator that is used to dynamically adjust the cross-sectional area of ​​the gas flow through the supply path according to the control signal, thereby changing the gas pressure. The regulating valve can be designed as a proportional solenoid valve or a servo control valve, with precise opening adjustment function, and the response speed usually reaches milliseconds to ensure the real-time pressure regulation. To further improve stability, a pressure buffer chamber can be designed inside the valve body to reduce the interference of sudden changes in gas flow rate on the regulation process.

[0064] The signal processing unit connects the pressure sensor and the control processing unit to receive the pressure signal and convert it into a standardized digital signal, while monitoring the signal fluctuation to eliminate noise. The signal processing unit has an embedded pressure calibration algorithm that can dynamically adjust the offset value and gain parameters of the sensor output to ensure the accuracy and consistency of the pressure measurement. In addition, the unit can calculate the average value of the detected pressure data in a short period of time to filter out the instantaneous pressure fluctuations caused by gas flow fluctuations.

[0065] The control interface is responsible for data exchange with the control processing unit, receiving the pressure set value from the control processing unit, and returning the execution result of the pressure regulating valve to the control processing unit to achieve closed-loop pressure control. This interface usually uses a digital communication protocol, such as Modbus or CAN bus, to ensure the stability and real-time performance of data transmission. In more complex designs, the pressure control module can also communicate directly with the gas flow control module to achieve joint optimization of pressure and flow.

[0066] The design and layout of the pressure control module are directly related to its performance. The module is usually installed upstream of the gas supply path, close to the gas injection module, to ensure that the response speed of the pressure regulation can meet the real-time requirements of the system. In addition, to avoid the impact of external environmental changes on the performance of the module, the housing of the pressure control module is made of corrosion-resistant and airtight materials, such as stainless steel or high-strength engineering plastics, and is equipped with a sealing structure.

[0067] In actual operation, the role of the pressure control module is reflected in many aspects. First, by adjusting the gas pressure, the module can control the gas flow rate entering the water, thereby achieving precise control of the bubble particle size. When the system target bubble concentration is high, the pressure control module will increase the gas injection pressure to ensure that the gas can be evenly dispersed in the water in a shorter time; in the lower concentration mode, the module will reduce the gas pressure to avoid excessive dispersion of the gas and lead to a decrease in dissolution efficiency. Secondly, the module can also maintain pressure stability during the bubble generation process. The pressure of the gas supply bottle may gradually decrease due to reduced usage. The pressure control module can dynamically compensate for the pressure drop by adjusting the opening of the valve to ensure the consistency of bubble generation.

[0068] The pressure control module can work with the gas type identification module to automatically adjust the pressure range according to different gas types. For example, carbon dioxide has a higher dissolution efficiency and is suitable for a lower pressure range, while nitrogen requires a higher pressure to form a uniform bubble distribution. The module can also dynamically optimize the pressure regulation strategy based on environmental conditions (such as temperature and humidity). For example, in a high temperature environment, the module will appropriately increase the gas pressure to compensate for the reduction in dissolution efficiency.

[0069] By linking with the control processing unit, the pressure control module can provide the system with stable and precise gas injection conditions, greatly improving the quality and consistency of the bubble water. Its design not only meets the basic needs of the current intelligent bubble water machine for pressure control, but also significantly improves the intelligence level of the system by introducing high-precision sensing technology, fast-response adjustment mechanism and multi-parameter linkage control, laying an important foundation for realizing intelligent control of high-quality bubble water.

[0070] Furthermore, the pressure control module is specifically used for:

[0071] Detecting real-time gas pressure and gas flow in a gas supply path, and comparing the real-time gas pressure with a preset target pressure;

[0072] Based on the comparison results, a pressure deviation signal is generated, and combined with the current gas flow information, the gas injection pressure is dynamically adjusted to optimize the bubble size and distribution.

[0073] The role of the pressure control module in the intelligent bubble concentration control system of the sparkling water machine is to monitor and dynamically adjust the gas injection pressure in real time, thereby optimizing the particle size and distribution of the bubbles. The module uses integrated sensors and control algorithms to accurately coordinate the relationship between gas pressure and gas flow to meet the high requirements for bubble generation conditions during system operation.

[0074] The pressure control module first obtains the current pressure and gas flow in the gas supply path in real time through the pressure sensor and flow meter. The pressure sensor is installed in the supply path of the gas injection module, which can convert the detected gas pressure into an electrical signal and transmit this signal to the processing unit of the pressure control module. At the same time, the flow meter detects the real-time flow of the gas and synchronously transmits the flow data to the pressure control module. These data constitute the core input information for the pressure control module to calculate and adjust.

[0075] After receiving the real-time pressure and flow data, the module compares the current pressure value with the preset target pressure. The target pressure is a standard value preset based on the bubble concentration requirements and liquid environmental conditions set by the user. When there is a difference between the real-time pressure and the target pressure, the module generates a pressure deviation signal to quantify the size and direction of the difference. If the current pressure is lower than the target pressure, the deviation signal is positive, indicating that the gas pressure needs to be increased; if the current pressure is higher than the target pressure, the deviation signal is negative, indicating that the gas pressure needs to be reduced.

[0076] Based on the pressure deviation signal, the pressure control module dynamically adjusts the gas injection pressure in combination with the current flow information. During the adjustment process, the module calculates the required pressure adjustment amount through the built-in control algorithm and sends the adjustment signal to the pressure regulating device in the gas injection module, such as a variable solenoid valve or a servo control valve. The pressure regulating device responds quickly to the signal sent by the module and achieves precise pressure regulation by changing the resistance of the gas injection path or adjusting the opening of the valve.

[0077] While making dynamic adjustments, the pressure control module also takes into account the coupling relationship between flow and pressure. Since the gas flow directly affects the formation rate and particle size distribution of bubbles, the module will simultaneously analyze the flow information when adjusting the pressure. For example, when the gas flow is large, appropriately increasing the pressure can ensure the uniformity of the bubble particle size; conversely, when the flow is small, lowering the pressure can prevent the bubbles from being too concentrated or bursting. In this process, the control logic of the module is not only based on the pressure deviation value, but also combined with the dynamic change trend of the gas flow to ensure the stability and accuracy of the control results.

[0078] In addition, the pressure control module has a built-in closed-loop feedback control mechanism. After each pressure adjustment, the module will monitor the adjustment result in real time and make a new comparison with the target pressure. If there is still a deviation after the adjustment, the module will further refine the adjustment parameters until the actual pressure reaches the target range. Closed-loop control ensures the accuracy of the entire pressure adjustment process and avoids abnormal bubble generation caused by over-adjustment or under-adjustment.

[0079] Through the above design, the pressure control module can accurately adjust the gas injection pressure under complex operating conditions to achieve optimal control of bubble size and distribution. The innovation of this module is that it not only adjusts the pressure independently, but also comprehensively considers the relationship between gas flow and bubble generation dynamics, thereby significantly improving the quality and consistency of the sparkling water.

[0080] The control processing unit 105 is communicatively connected with the gas injection module, the water temperature control module, the concentration sensing module and the pressure control module, and is used for receiving the concentration signal of the concentration sensing module; comparing the concentration signal with the target bubble concentration to generate a concentration deviation value; adjusting the gas flow parameter of the gas injection module, the water temperature parameter of the water temperature control module and the pressure parameter of the pressure control module according to the concentration deviation value, and dynamically correcting the bubble concentration and particle size; and calculating the target bubble concentration based on a preset mode or a user-defined setting.

[0081] The control processing unit 105 is the core component of the present invention, which is responsible for comprehensive management and dynamic control of the entire intelligent bubble concentration control system of the sparkling water machine. Through communication connection with the gas injection module, water temperature control module, concentration sensing module and pressure control module, the control processing unit can receive multiple real-time signals and perform complex logic processing to ensure accurate regulation of bubble concentration, particle size and distribution, and ultimately achieve the generation of high-quality sparkling water.

[0082] The control processing unit includes a processor, memory, input and output interfaces, and embedded control software. The processor can be a high-performance microcontroller (such as the ARM Cortex-M series) or an embedded system chip (such as FPGA or SoC), which has powerful computing and real-time processing capabilities, can quickly respond to external signal changes and generate control instructions. The memory is used to store key parameters, historical data, and control algorithms for system operation, and can dynamically update the stored content according to user needs.

[0083] The control processing unit first receives the concentration signal from the concentration sensing module, which contains the actual bubble concentration information of the bubble water. By comparing the concentration signal with the target bubble concentration value, the control processing unit calculates the concentration deviation value in real time and generates adjustment instructions accordingly. In order to achieve precise control, the control processing unit uses a closed-loop control algorithm, such as proportional-integral-differential (PID) control or fuzzy control algorithm. These algorithms can dynamically adjust the flow parameters of the gas injection module, the output temperature of the water temperature control module, and the pressure value of the pressure control module according to the concentration deviation value, thereby realizing real-time optimization of bubble concentration and particle size under the linkage adjustment of multi-dimensional parameters.

[0084] The embedded software module in the control processing unit consists of multiple submodules, including a data acquisition module, a parameter calculation module, a control strategy module, and a communication module. The data acquisition module is responsible for receiving real-time signals from various sensors, including concentration signals, water temperature signals, pressure signals, and gas flow signals. The parameter calculation module calculates the optimal working parameters of each execution module based on the mode or target value set by the user. The control strategy module generates adjustment instructions based on the calculation results and sends the instructions to the corresponding execution module.

[0085] In addition, the control processing unit supports multiple working modes, including preset mode and user-defined mode. In the preset mode, the user selects a specific bubble concentration requirement, such as "high concentration mode" or "low concentration mode" through the user interaction unit. The system automatically adjusts the working state of each module according to the preset optimal parameters. In the user-defined mode, the control processing unit allows the user to manually set parameters such as bubble concentration, water temperature and gas pressure to meet the user's personalized needs.

[0086] Another important function of the control processing unit is to record and analyze historical data. By analyzing the historical records of concentration changes, temperature fluctuations, and pressure adjustments, the control processing unit can optimize the control strategy and improve the efficiency and stability of the system. For example, the system can identify the nonlinear relationship between gas injection flow and pressure regulation, and compensate for possible errors by adjusting the weight parameters of the control algorithm, thereby achieving more precise control.

[0087] In order to enhance the intelligence level of the system, the control processing unit can also analyze the user's usage habits and environmental conditions by integrating machine learning algorithms. For example, the system can predict the bubble concentration that the user may choose based on the changes in ambient temperature and adjust the relevant parameters in advance to achieve a seamless operation experience. At the same time, the control processing unit can dynamically optimize the calculation model of the bubble retention time evaluation module to provide users with more accurate optimal drinking recommendations.

[0088] The control processing unit is connected to the user interaction unit through the communication module to realize two-way information transmission between the user and the system. The user can view the current state of bubble water generation, adjust mode parameters or receive drinking suggestions through the mobile application or touch panel. The control processing unit transmits key data of system operation to the user interface, including bubble concentration, water temperature, gas flow and system fault alarm information. In addition, the control processing unit supports remote upgrade function, and users can download the latest control algorithms and functional modules through the wireless communication module, thereby continuously improving the performance and applicability of the system.

[0089] In order to ensure the safety and reliability of system operation, the control processing unit is designed with multiple protection mechanisms. For example, when the concentration sensor module or other execution modules detect abnormal signals, the control processing unit can trigger the automatic protection mode, suspend the system operation and issue an alarm to the user. At the same time, the control processing unit has a built-in redundant data storage function to ensure that important data will not be lost when the system is powered off or fails.

[0090] Through close integration with each module, the control processing unit plays the role of the command center in this system, which can flexibly coordinate the working status of multiple modules and efficiently perform complex control tasks. It improves the quality of sparkling water through closed-loop control of multi-dimensional parameters, intelligent regulation strategy and user-friendly interactive design.

[0091] Furthermore, the control processing unit is specifically used for:

[0092] Receive the real-time bubble concentration signal C detected by the concentration sensor module current and compare it with the target bubble concentration C target Compare and generate concentration deviation value ΔC = C target -C current ;

[0093] C target is the target bubble concentration, in mol / L, set by the user through the user interaction unit; C current is the current bubble concentration detected in real time by the concentration sensor module, in mol / L;

[0094] According to the following formula 1, calculate the new gas flow rate:

[0095]

[0096] Among them, F gas，new is the new gas flow rate, in L / min, indicating the adjusted gas injection speed;

[0097] F gas，old is the current gas flow rate in L / min, monitored by the gas injection module;

[0098] k 1 , k 2 is the empirical optimization constant; k 1 k is the concentration deviation influence coefficient, the recommended value is 0.5; 2 is the concentration change rate influence coefficient, the recommended value is 0.1;

[0099] is the concentration change rate, which is calculated by the concentration sensor module through the concentration change in a short period of time;

[0100] Calculate the new water temperature according to the following formula 2:

[0101]

[0102] Among them, T water，new is the new water temperature, is the water temperature after dynamic adjustment;

[0103] T water，old is the current water temperature;

[0104] ΔH is the dissolution enthalpy change, in J / mol, which describes the heat change when the gas dissolves in water and can be calculated using the following formula:

[0105]

[0106] Where R is the gas constant; T is the average temperature; k H1 is at temperature T 1 Henry's coefficient under H2 is at temperature T 2 Henry's coefficient under

[0107] For example, the k of carbon dioxide at 298 K isH =45mol / (L·P a ), k at 308K H =18mol / (L·P a ), calculate its dissolution enthalpy change as follows:

[0108] 1. Take the average temperature T = (298 + 308) / 2 = 303K;

[0109] 2. Calculation

[0110] 3. Substitute into the empirical formula:

[0111] ΔH=--8.314·303·0.916≈-19.4kJ / mol

[0112] This result is close to the actual experimental value and is sufficient to meet the needs of many engineering applications. The ΔH in Formula 2 can adopt this estimated value, that is, ΔH is -19.4.

[0113] k 4 , k 5 is the empirical optimization constant; k 4 k is the thermal influence coefficient of dissolution, the recommended value is 1.0; 5 is the concentration deviation influence coefficient, and the recommended value is 0.1.

[0114] Calculate the new gas pressure according to Formula 3 below:

[0115]

[0116] Among them, P gas，new is the new gas pressure, in P a , represents the dynamically adjusted gas injection pressure;

[0117] P gas，old is the current gas pressure, in P a , monitored by the pressure control module;

[0118] η water is the viscosity, the unit is P a ·s, here we can take a typical value of 1.0×10 -3 P a ·s;

[0119] k 6 , k 7 These are empirical optimization constants, and the recommended values ​​for both are 0.1.

[0120] According to the new gas flow rate, the new water temperature and the new gas pressure, the gas flow rate parameters of the gas injection module, the water temperature parameters of the water temperature control module and the pressure parameters of the pressure control module are adjusted respectively.

[0121] The user interaction unit 106 includes a mobile application or a touch panel, which is used to receive the user's mode selection, concentration setting, and display the generation status of the bubble water.

[0122] The user interaction unit 106 is a key module in the system that directly interacts with the user. It undertakes multiple functions such as information input, mode selection, and status feedback, provides users with an intuitive and convenient operation interface, and significantly improves the usability and personalized experience of the system. The user interaction unit can include a mobile application, a touch panel, or other forms of user interface devices, and through communication connection with the control processing unit 105, it can achieve comprehensive control of the operating status of the bubble water machine.

[0123] The core design of this module is to provide users with a simple and clear way of interaction. The touch panel can be designed as a high-resolution color screen that supports multi-touch and can clearly display the real-time parameters of bubble water generation, including information such as bubble concentration, water temperature, gas flow and current mode. Users can complete mode switching, target concentration setting and other parameter adjustments through touch gestures. The mobile application uses a smartphone or tablet as an interactive carrier, provides wireless connection function, supports Bluetooth or Wi-Fi protocol, and allows users to complete the same functions through remote operation. In addition, the mobile application can expand more functions, such as recording user usage habits, recommending optimization settings, and pushing system maintenance reminders to users.

[0124] In order to ensure that the needs of different users can be met, the user interaction unit is designed with a variety of preset modes and custom functions. Preset modes such as "high concentration mode", "low concentration mode" or "children's mode" optimize system parameters according to different usage scenarios, so that ordinary users can quickly generate the required sparkling water without in-depth understanding of technical details. The custom function allows advanced users to manually enter parameters such as target concentration, water temperature and pressure, and view the system's response effect in real time through the interface to meet more personalized needs.

[0125] The module also integrates a status feedback function to show the user the system operation status in real time. For example, when the control processing unit detects that the concentration deviation value is beyond the normal range, the user interface will pop up a warning message to prompt the user to adjust the parameters or check the equipment. At the same time, the user interaction unit will display the working status of the concentration sensing module and the pressure control module to help users intuitively understand the health status of the equipment. If a fault is detected or maintenance is required, the user interaction unit can provide detailed fault analysis and guide the user to complete the necessary operations, such as replacing the gas tank or cleaning the sensor.

[0126] In order to improve the user experience, the user interaction unit not only focuses on functionality, but also on visual and operational beauty and smoothness. The interface design of the touch panel and mobile application adopts a modular layout, and each functional area has been carefully optimized to ensure a clear information hierarchy to avoid user confusion during operation. For example, the main interface displays the current mode and basic parameters, the secondary interface provides detailed adjustment options, and fault warnings and maintenance prompts attract user attention through pop-up windows or highlight effects.

[0127] The user interaction unit also has intelligent learning and recommendation functions. By recording the user's operation history and parameter setting habits, the system can analyze the user's preferences and provide optimization suggestions when appropriate. For example, if the user frequently selects a specific bubble concentration, the system will automatically recommend the corresponding preset mode and prompt the user to save it as a shortcut mode. At the same time, combined with the data provided by the bubble retention time evaluation module 108, the user interaction unit can display the best drinking suggestions in real time, such as "The current bubble water is suitable for drinking" and "The bubble concentration is about to decrease, please drink it as soon as possible".

[0128] In the design of modern smart home appliances, remote control and cloud connection are important development directions, and user interaction units also fully reflect this trend. Through the cloud connection function of the mobile application, users can not only remotely monitor the operation status of the device, but also receive device firmware updates and optimization solutions. System updates can include new preset modes, algorithm optimizations, or interface improvements. These updates will be pushed to users in the form of notifications and guide users to easily complete the update operation. In addition, users can choose to upload the operation data of the device to the cloud to generate long-term usage reports or personalized service recommendations.

[0129] The hardware design of the user interaction unit focuses on durability and environmental adaptability. For example, the touch panel adopts a waterproof design to work reliably in humid environments, and its screen material is scratch-resistant to extend the service life of the device. The communication module of the mobile application adopts a low-power design to ensure that long-term connection will not cause excessive battery consumption on the user's device.

[0130] Through efficient linkage with the control processing unit, the user interaction unit not only achieves comprehensive functions, but also sets a new benchmark in intelligence and personalization. Users can easily control the complex process of sparkling water production and enjoy an optimized drinking experience through an intuitive interface. This design fully meets the needs of different types of users, and can provide consistent convenience and high-quality services from ordinary families to professional fields.

[0131] Furthermore, the user interaction unit includes a touch panel, which is configured to display detailed status information of the bubble water generation process through a multi-level menu, including real-time bubble concentration, water temperature, gas pressure and predicted values ​​of bubble retention time, and the user can expand the menu level by level through touch operation to view detailed information, and support adjusting the set values ​​of bubble concentration, water temperature and pressure through sliding and clicking gestures, thereby realizing personalized control;

[0132] The user interaction unit includes a mobile application, which is configured to support remote real-time control and status monitoring functions, wherein the user can remotely set the target concentration, water temperature and pressure of the sparkling water through the mobile application, and receive push notifications of the real-time generation status, the notification content including the current bubble concentration, water temperature, pressure and the best drinking time recommendation for the sparkling water, and the application can automatically recommend generation parameters based on the user preference history to optimize the user experience.

[0133] The user interaction unit provides a new multi-dimensional interaction mode, which combines the touch panel and mobile application to significantly improve the user's control ability and user experience of the sparkling water machine. The touch panel and mobile application each have unique functions, and at the same time realize the seamless connection between local operation and remote monitoring, meeting the user's diverse needs for personalized settings and real-time feedback.

[0134] The touch panel is designed as an embedded interface, directly integrated into the external operating area of ​​the sparkling water machine, through which users can easily view detailed status information of the sparkling water generation. The touch panel adopts a multi-level menu design, which can gradually expand detailed data according to user needs. For example, users can see a brief overview of key parameters such as bubble concentration, water temperature, and pressure on the initial interface. When they need to understand more, they can further expand and view the real-time change trend, historical data and system analysis results of each parameter through touch gestures. The sensitivity and intuitiveness of touch operation allow users to quickly understand the operation status of the system and easily adjust settings.

[0135] To achieve precise and personalized control, the touch panel supports multiple gestures such as sliding and clicking. For example, users can adjust the target value of bubble concentration by sliding, and switch the setting range of water temperature and pressure by clicking. All adjustments will take effect in real time, and the expected effect of the parameter change, such as the adjusted bubble retention time and water saturation state, will be updated synchronously in the display area of ​​the touch panel. This instant feedback function not only enhances the interactive feeling of operation, but also enables users to optimize parameter settings based on the real-time display results to ensure the quality of the sparkling water meets expectations.

[0136] The mobile app further expands the operating range of the system, providing users with remote control and status monitoring functions through smart devices. Users can set the target concentration, water temperature and pressure parameters of the sparkling water through the app anytime and anywhere without directly contacting the machine. The mobile app also supports push notifications. During the process of sparkling water generation, users can receive real-time updates on the current bubble concentration, water temperature, pressure and bubble retention time. The push notification content includes not only the current status data, but also optimization suggestions, such as the best drinking time range prompt. This active push function ensures that users can keep abreast of system dynamics and make adjustments or decisions even if they are not next to the device.

[0137] It is worth noting that the mobile application is not limited to real-time control and monitoring, but also has user preference analysis and intelligent recommendation functions. The system will record the user's historical setting parameters, such as commonly used bubble concentration, water temperature range, and preferred bubble retention time, and generate personalized recommendations based on these data through a built-in algorithm. For example, if a user often chooses a certain bubble concentration and a specific water temperature, the system will actively recommend the same parameter settings in similar usage scenarios in the future, reducing the user's adjustment time and improving operational convenience. This optimized design based on user behavior analysis significantly enhances the system's intelligence level and user stickiness.

[0138] The combination of touch panel and mobile application not only reflects the comprehensiveness of the user interaction unit in terms of functions, but also realizes seamless collaboration from local operation to remote control. Whether it is local intuitive display and adjustment, or remote real-time monitoring and intelligent push, the user interaction unit is systematically designed around user experience and efficiency, making the entire sparkling water machine system more in line with the trend of modern smart devices, greatly improving the user's operational satisfaction and the market competitiveness of the system.

[0139] Furthermore, the user interaction unit includes a voice interaction module, which is used to receive the user's voice commands through natural language processing technology, and adjust the bubble concentration, water temperature and pressure parameters according to the commands, and at the same time feedback voice broadcast information of the generated status, including the current bubble concentration, pressure adjustment progress and predicted bubble retention time. The voice interaction module supports multi-language recognition and personalized settings of voice commands to enhance the user's contactless control experience.

[0140] The voice interaction module introduces a new contactless operation mode in the intelligent bubble concentration control system of the sparkling water machine. Through natural language processing technology, the module can accurately identify and analyze the user's voice commands, adjust the system parameters in real time, and provide users with clear and real-time voice feedback information. This interaction mode not only simplifies the operation process, but also significantly improves the intelligence and convenience of the user experience.

[0141] The core function of the voice interaction module is to receive the user's voice commands and parse their content. The module has a built-in high-precision voice recognition engine that can accurately capture the user's voice input. Even in a noisy environment, it can improve the accuracy of voice recognition through noise reduction algorithms. Users can directly issue commands through natural language, such as "increase the bubble concentration a little bit", "set the water temperature to ten degrees", "reduce gas pressure", etc. The voice interaction module can quickly parse the specific meaning of the command and extract the target parameters. The parsed instructions will be passed to the control processing unit to drive related modules (such as gas injection module, water temperature control module and pressure control module) to perform corresponding operations.

[0142] During the adjustment process, the voice interaction module also has a real-time voice feedback function. When the system completes the command adjustment or is performing the adjustment, the module will generate corresponding voice broadcast information. For example, after the user issues a command to adjust the bubble concentration, the module will broadcast the specific value of the current concentration and the adjustment progress through voice; when the user requests to query the generation status, the module can feedback detailed information, including the current bubble concentration, water temperature, gas pressure, and predicted bubble retention time. These feedback information are clear and accurate, ensuring that users always understand the operating status of the system.

[0143] The multi-language recognition function of the voice interaction module is one of its important innovations. The module supports voice input and output in multiple languages, and users can choose the language environment that suits them according to their needs. Whether it is common English, Chinese, or local dialects of China, the module can support the recognition and broadcasting of different languages ​​through the expansion and dynamic update of the language library. In addition, the module allows users to personalize voice commands. For example, users can define short voice commands for common operations, such as "general settings" or "cold water mode", and the system will quickly perform a series of parameter adjustments based on the predefined mapping relationship, without having to enter specific commands one by one each time.

[0144] The design of the voice interaction module also pays special attention to the optimization of the contactless control experience. In many practical scenarios, such as in the kitchen environment or when both hands are occupied, users may not be able to touch the screen or use mobile applications, and voice interaction provides a convenient solution. Users can complete complex settings and monitoring operations only through voice, which greatly improves the ease of use of the system.

[0145] By introducing natural language processing technology, multi-language support and personalized setting functions, the voice interaction module has greatly improved the intelligent level of user interaction, so that the intelligent bubble concentration control system of the sparkling water machine can not only meet the traditional parameter adjustment needs, but also provide services in a more user-friendly way. This contactless, intuitive and efficient interaction method has laid a solid foundation for the expansion of the system's application scenarios and the improvement of user satisfaction.

[0146] The communication module 107 is connected to the control processing unit and the user interaction unit for realizing remote operation and status feedback of the system.

[0147] The communication module 107 is the core bridge connecting the control processing unit and the user interaction unit in this system. Its function is to realize two-way data transmission and real-time feedback to ensure the efficient operation of the intelligent bubble concentration control system of the bubble water machine and improve the user experience. The design of the communication module takes into account the diverse needs of modern smart devices, including stability, real-time, security and adaptability, so as to ensure that users can easily control the device and obtain system status information remotely or locally.

[0148] The communication module supports multiple communication methods to meet the needs of different usage scenarios. Its main communication methods include wireless communication and wired communication. In terms of wireless communication, the communication module integrates Wi-Fi, Bluetooth and Bluetooth Low Energy (BLE) technologies. Wi-Fi communication is suitable for scenarios that require remote control, such as when users want to remotely start or adjust the operating status of a sparkling water machine outside their home through a mobile application; Bluetooth is suitable for short-distance fast connection and local control, such as instant settings and feedback when users operate equipment in the kitchen. Bluetooth Low Energy significantly reduces energy consumption while maintaining a long connection time, which is very suitable for scenarios where equipment operation is continuously monitored. Wired communication methods such as USB or RS485 are mainly used in industrial environments or scenarios that require high reliability to ensure the stability and anti-interference ability of data transmission.

[0149] The hardware part of the communication module consists of a communication chip, antenna, signal processing unit, and power management unit. The communication chip is the core of the module and is responsible for sending and receiving signals. The chip usually uses high-performance, low-power models, such as chips that support dual-band Wi-Fi (2.4GHz and 5GHz) to enhance signal coverage and transmission rate. The antenna design optimizes the gain and directivity of the signal to ensure that the device can maintain a stable connection in different locations. The signal processing unit decodes, filters, and corrects the data to ensure the integrity and accuracy of the transmitted data.

[0150] The communication module interacts with the control processing unit and the user interaction unit through standardized protocols. Commonly used communication protocols include MQTT, HTTP, Modbus, and custom binary protocols. The MQTT protocol is suitable for transmitting real-time status data and control instructions due to its lightweight and high efficiency; the HTTP protocol can be used for remote access of mobile applications and realizes two-way data transmission through a secure HTTPS encrypted channel; Modbus provides a stable and reliable communication method for industrial applications, suitable for complex industrial environments.

[0151] The communication module integrates data encryption and user authentication mechanisms to ensure the communication security of the system. Data encryption adopts the AES-256 standard to protect user settings, device status and other sensitive information from being leaked or tampered during transmission. Authentication is achieved through the OAuth 2.0 protocol or similar authentication methods to limit unauthorized access and prevent improper control or interference of the device.

[0152] The communication module also has status monitoring and adaptive adjustment functions. It can monitor the connection status and signal strength of the device in real time, and try to automatically reconnect when it detects a connection interruption or weak signal. In order to optimize the utilization of the system's network resources, the communication module has built-in traffic management functions. For example, when the network is busy, the module will give priority to transmitting high-priority data (such as fault alarms or control instructions) and delay the transmission of low-priority data (such as historical status records).

[0153] In actual operation, the communication module provides strong support for the intelligence of the system. For example, when the user sets the target bubble concentration through the mobile application, the communication module will quickly transmit the command to the control processing unit to trigger the corresponding regulation process. At the same time, the communication module will transmit key status information such as real-time concentration, gas flow, water temperature and bubble retention time back to the user interaction unit for users to view at any time. In the remote operation scenario, users can start the device, modify parameters or receive device operation reports through mobile devices, and can fully control the system even if they are in a different place.

[0154] To further enhance the user experience, the communication module supports remote updates (OTA) of device firmware. Users can push update packages through the cloud, and the communication module will automatically download and install the new version of the software after receiving the update command, ensuring that the device always maintains the latest functions and optimal performance. In addition, the communication module can also upload the device's operating data to the cloud based on the user's authorization, which can be used to generate long-term operation reports or optimize the device's control algorithm.

[0155] The design of the communication module also fully considers future scalability. For example, it can be compatible with the home IoT platform and realize voice control or scene linkage through integration with the smart home system. Users can start the device or select a specific mode through simple voice commands, and at the same time link the operating status of the bubble water machine with other home appliances (such as smart refrigerators or air purifiers) to build a more intelligent home experience.

[0156] Through close integration with the control processing unit and the user interaction unit, the communication module 107 not only realizes the basic functions of data transmission and remote control, but also provides comprehensive technical support for the system through security assurance, status monitoring, adaptive adjustment and scalability design.

[0157] The bubble retention time evaluation module 108 is used to predict the bubble retention time of the generated bubble water based on the real-time signal of the concentration sensor module and the calculation of the control processing unit, and provide the best drinking suggestion to the user through the user interaction unit.

[0158] The bubble retention time evaluation module 108 is an important part of the system. Its main function is to predict the retention time of bubbles in the bubble water based on the real-time bubble concentration signal provided by the concentration sensing module and the dynamic calculation of the control processing unit, and provide optimized drinking suggestions to the user accordingly. The design of this module is intended to enhance the user's subjective perception of the quality of the bubble water, while maximizing the drinking value of the bubble water, so that the user can enjoy the drink in the best state of bubbles.

[0159] This module calculates the stability and residence time of bubbles in water by comprehensively analyzing multiple parameters such as bubble concentration, particle size distribution, water temperature and gas pressure, using mathematical modeling and empirical formulas. Specifically, the residence time of bubbles is affected by many factors. For example, higher bubble concentration and smaller bubble size often mean longer residence time, while higher water temperature may accelerate the dissipation of bubbles. The bubble residence time assessment module quantifies these complex relationships into a dynamic prediction model, and the control processing unit outputs real-time results based on the model.

[0160] The core of the module is a multivariable calculation engine with a built-in dynamic model of the physical behavior of bubbles and a parameter optimization algorithm. The calculation engine dynamically updates the input variables of the model based on real-time data, such as the current bubble concentration value provided by the concentration sensor module, the gas injection pressure monitored by the pressure control module, and the water temperature parameter detected by the water temperature control module. Through multiple iterative calculations, the module can accurately predict the residence time of bubbles under specific conditions. For example, when the user sets the goal of high-concentration bubble water, the evaluation module will calculate the optimal residence time range of bubbles in this state based on the data provided by the system and provide prompts to the user.

[0161] In order to adapt to the needs of different users, the module is designed to take into account the diversity of drinking preferences. For example, some users may want bubbles to last longer, while others pay more attention to the burst of bubbles when they enter the mouth. To this end, the bubble retention time evaluation module allows users to select preferences in the mobile application or touch panel, such as "high stability" or "strong impact". The system will adjust the model parameters based on these choices to predict the bubble retention time in different modes.

[0162] The calculation results of this module are not only fed back to the user in numerical form, but also presented in an intuitive way. For example, the user interface can graphically display the changing trend of the bubble state, including the decay curve of the bubble concentration over time or the prediction comparison chart under different conditions. This visual design helps users intuitively understand the changing law of bubble retention time, so as to make the best decision in different usage scenarios.

[0163] An important extended function of the bubble retention time evaluation module is the deep integration with the user interaction unit. Through real-time calculation and prediction, the module can actively prompt drinking suggestions when the user starts the system. For example, when the user generates sparkling water, the system may prompt "the best drinking time is within 10 minutes" and dynamically update this suggestion based on real-time monitoring data. If the user wants to extend the retention time of bubbles, the module will also provide optimization suggestions, such as lowering the water temperature or increasing the gas injection pressure.

[0164] In order to further improve the module's intelligence level, the module introduces a data-driven optimization algorithm. By recording the user's usage habits and actual drinking feedback, the system can gradually improve the parameters of the prediction model. For example, if the user repeatedly chooses to drink after the bubbles have obviously weakened, the system will adjust the model's threshold based on this behavior and optimize the prediction results to be closer to the user's actual needs.

[0165] At the industrial design level, the bubble residence time evaluation module achieves a balance between performance and energy consumption through a combination of efficient hardware and software. The hardware part of the module uses an embedded microprocessor that can run complex computing tasks with low power consumption. The software part reduces redundant calculations through algorithm optimization to ensure real-time response capabilities under multi-parameter conditions. The module is also designed with a self-learning function to improve prediction accuracy and system adaptability by continuously iterating and optimizing the calculation model.

[0166] Unlike traditional sparkling water machines that rely mainly on static parameter designs, the bubble retention time evaluation module can dynamically adjust the calculation strategy to respond to changes in environmental conditions in real time. For example, in a high temperature environment, the module will take into account the adverse effects of rising water temperature on bubble retention time and compensate by optimizing other parameters (such as increasing gas concentration or adjusting pressure) to maximize the quality of the sparkling water.

[0167] Through tight integration with the entire system, the bubble retention time evaluation module not only improves the quality of sparkling water, but also significantly enhances the user experience. It not only meets the diverse needs of different users for bubble status, but also guides users to enjoy sparkling water more scientifically through intelligent calculation and prompt functions.

[0168] Furthermore, the bubble residence time assessment module is specifically used for:

[0169] According to the following formula 4, the bubble retention time T of the generated sparkling water is predicted bubble :

[0170]

[0171] Where ΔH is the dissolution enthalpy change; k mass is the gas mass transfer coefficient; A is the effective exchange area of ​​the bubble; C sat is the saturation concentration of the gas under current conditions; C current v is the current gas concentration in the bubble water; flow is the liquid convection intensity; v crit is the critical velocity; α is the temperature correction coefficient; T water is the current water temperature; β is the pressure correction coefficient; P gas is the current gas pressure.

[0172] The bubble retention time evaluation module of this embodiment is used to predict the bubble retention time T of the generated bubble water. bubble The residence time is calculated by Equation 4, which aims to accurately estimate the life cycle of bubbles from generation to dissipation based on the physicochemical properties of bubble dissolution and the liquid flow environment.

[0173] The formula is:

[0174]

[0175] This formula consists of multiple parts, which reflect the comprehensive influence of factors such as dissolution thermodynamics, mass transfer kinetics, liquid convection, temperature and pressure on the bubble residence time.

[0176] First, ΔH is the enthalpy change of dissolution, in J / mol. It represents the energy change when a gas dissolves in a liquid and is the key driver of the gas dissolution rate. For carbon dioxide, its typical value is -19.4 kJ / mol, which can be found in a chemistry handbook or determined experimentally. The ΔH in Equation 4 can be calculated using -19.4.

[0177] k mass is the gas mass transfer coefficient in m / s. It describes the rate at which gas diffuses from the bubble surface into the liquid and depends on the viscosity of the liquid, the temperature and the properties of the gas. The typical value is 0.001 m / s and can be calibrated experimentally in this system. Increasing the agitation or convection intensity of the liquid will increase k mass The value of .

[0178] A is the effective exchange area of ​​the bubble, in m 2 The exchange area A can be estimated by the gas flow rate and injection conditions.

[0179] Assume that the volume flow rate of injected gas is F gas(Unit: L / min), the effective exchange area can be calculated by the following formula:

[0180] A=k A ·F gas

[0181] Among them, k A is an empirical constant related to the geometry of the injection system, with a recommended value of 10 -6 m 2 / L / min.

[0182] C sat is the saturation concentration of the gas under current conditions, in mol / L. It is calculated by Henry's law:

[0183] C sat =k H ·P gas

[0184] Among them, k H is Henry coefficient, unit is mol / (L·P a ), with a typical value of 29.4 mol / (L·P a )(Carbon dioxide); P gas It is the current gas pressure detected by the pressure sensing module.

[0185] C current It is the gas concentration in the current bubble water, in mol / L. It is detected and provided in real time by the concentration sensor module.

[0186] The effect of liquid convection on the bubble residence time is described.

[0187] v flow It is the convection intensity of the liquid, measured in m / s, and can be calculated from the parameters of the flow sensor or injection module.

[0188] Critical flow velocity v crit It is an experimental calibration value, and the recommended value is 0.01m / s. This item reflects the characteristic that bubbles are more likely to escape from the liquid surface when the convection intensity is high.

[0189] is the temperature correction term, where T water The current water temperature in K, provided by the water temperature control module. The correction coefficient α describes the effect of water temperature on the bubble dissolution rate, and the recommended value is 0.01.

[0190] is the pressure correction term, which reflects the effect of gas pressure on the residence time. The recommended value of the correction factor β is 0.001. Higher gas pressure will extend the residence time of bubbles because it increases the resistance of the gas in the bubble to release into the liquid.

[0191] After multiplying each part of the formula, the comprehensive factors affecting the bubble residence time are fully described. T calculated by the formula bubble , directly represents the average life cycle of bubbles. This result can be fed back to the user interface in real time to remind users of the best time to drink sparkling water or to further optimize system parameters.
