[0023] Figure 1 This is a schematic diagram of an intelligent bubble concentration control system for a bubble water machine provided in the first embodiment of this application. Detailed Implementation

[0024] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0025] The first embodiment of this application provides an intelligent bubble concentration control system for a bubble water machine. Please refer to... Figure 1 This figure is a schematic diagram of the first embodiment of this application. The following is in conjunction with... Figure 1 The first embodiment of this application provides a detailed description of an intelligent bubble concentration control system for a bubble water machine.

[0026] The intelligent bubble concentration control system for the bubble 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 regulation system provided by the present embodiment, used to inject gas into water in a precisely controllable manner to achieve the generation of target bubble concentration. The module includes a gas supply unit, a flow regulation unit, an injection nozzle or diffuser, and an interface for communication with the control processing unit 105.

[0029] The gas injection module 101 obtains gas through the gas supply unit, which can be food-grade gas such as carbon dioxide, nitrogen, or oxygen, and the specific choice can be determined according to the target application and user demand. 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 by a pressure stabilizing valve to ensure stable 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 and ensure that the injected gas meets safety standards. If the gas purity is detected to be out of the required range, the module will send an alarm signal to the control processing unit to prevent further operation.

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

[0032] The flow regulation unit adjusts the flow size dynamically according to the concentration deviation value by receiving the flow parameters calculated by the control processing unit. For example, when the concentration sensing module 103 feedbacks that the bubble concentration is lower than the target concentration, the control processing unit increases the gas flow through the flow regulation 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] To further improve accuracy, the flow regulation unit can be equipped with a closed-loop control circuit, which combines an internal flow sensor to detect the actual gas flow and adjusts the valve opening through feedback to avoid concentration deviation caused by system error.

[0034] The injection nozzle or diffuser is the key interface between the gas injection module and water, which functions 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 micro-porous diffusion design, which uniformly diffuses gas in the form of tiny bubbles into water through multiple small pore diameters. This design can significantly increase the contact area between gas and water, thereby improving the stability and dissolution efficiency of the bubbles. In certain cases, guide vanes can be arranged around the diffuser to form a vortex structure, further optimizing the uniformity of bubble distribution.

[0036] In addition, to adapt to different concentration requirements, the nozzle can be designed as an adjustable aperture structure. Users can select different nozzle modes, such as "high concentration micro-bubble 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 with the control processing unit 105 through a communication interface to realize data exchange and instruction reception. The interface usually adopts digital signal communication mode, 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 parameter sent by the control processing unit and feedback the flow adjustment unit and the gas injection state in real time, including actual flow, gas pressure and nozzle opening state information. This information is used by the control processing unit to dynamically adjust the operating parameters of other modules (such as the water temperature regulation module 102 and the pressure regulation module 104) to form 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 adjustment unit of the gas injection module according to the difference between the set value and the real-time concentration. The flow adjustment unit adjusts the valve opening to inject gas into the nozzle at a set flow rate. At the same time, the pressure regulation 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 uniformly injected into the water through the nozzle, and the generated bubble concentration is detected in real time by the concentration sensing module 103 to form a closed-loop control.

[0040] Through the above structure and function design, the gas injection module 101 can realize high-precision and high-stability bubble generation, ensuring that the system can meet the performance requirements in various use scenarios, while significantly improving user experience and equipment reliability.

[0041] The water temperature regulation module 102 is connected with 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 regulation module 102 is an important part of the system, and its main function is to monitor and adjust the water temperature in real time to ensure that the water temperature can meet the uniformity and stability requirements of bubble distribution in 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 residence time of bubbles are directly affected by water temperature. The water temperature regulation module works with the gas injection module 101 to optimize the bubble concentration while effectively improving the quality of bubble water.

[0043] The water temperature regulation 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. To ensure the accuracy of water temperature regulation, a high-sensitivity semiconductor sensor or a thermistor can be selected as the water temperature sensor, which can capture water temperature changes with millisecond-level response time. This real-time water temperature feedback ensures that the module can quickly respond to water temperature fluctuations and avoid uneven bubble distribution or unstable bubbles due to large temperature changes.

[0044] The heating unit typically uses a resistance heater, a thin-film heater, or an immersion heating rod, and its power can be dynamically set according to the water volume and target temperature requirements. For example, when the water temperature is detected to be below the preset range, the heating unit quickly starts and heats the water temperature to the target value through precise power output. In the case of cooling, the cooling unit can use a thermoelectric refrigeration component or a cooling plate with a cooling circuit to quickly cool the water temperature to ensure it is within the set range. The cooling unit is particularly important in summer environments or high-frequency use cases, as the cooling function can effectively prevent the negative effects of high water temperature on bubble water quality.

[0045] The water temperature regulation module communicates with the control processing unit through a digital signal interface. The control processing unit dynamically adjusts the water temperature parameters based on the real-time concentration signal provided by the concentration sensing module 103 and the user's preset bubble concentration requirements. For example, when the bubble concentration requirement is high, the system will prioritize adjusting the water temperature to the temperature range that is best for bubble distribution (e.g., 4°C to 10°C) to enhance the stability of the bubbles in the water and extend their retention time. In low concentration mode, the water temperature may be set to a higher range to meet user demand for different bubble sensory experiences.

[0046] To further optimize the performance of the water temperature regulation module, a closed-loop control algorithm can be designed inside the module, which combines PID (Proportional-Integral-Derivative) 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 in the case of external environmental temperature changes or water volume changes, ensuring that the output water temperature is always stable within the target range. In addition, the module can store historical temperature data and combine it with data from the concentration sensing module and bubble retention time evaluation module to optimize future water temperature control strategies, improving the overall efficiency and user experience of the system.

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

[0048] To facilitate user maintenance, the water temperature regulation module can also be designed with cleaning and self-checking functions. In the long-term use process, minerals in the water may form deposits on the heating or cooling unit, affecting the performance of the module. Through the built-in cleaning mode, the system can periodically automatically clean the heating and cooling units, prolonging the service life of the module and ensuring the regulation accuracy. In addition, the self-checking function can monitor the running state of the module in real time, and issue an alarm to the user or automatically adjust the operating parameters when an abnormal condition is detected, to ensure the safety and stability of the system.

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

[0050] The concentration sensing module 103 is configured 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 sensing module 103 is one of the core components of the system, and its function is to detect the bubble concentration of the generated bubble water in real time and transmit this concentration value in the form of a signal to the control processing unit 105, providing key data support for subsequent dynamic adjustment and closed-loop control. The design of the concentration sensing 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 regulation.

[0052] The module mainly consists 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, usually composed of a laser emitter and a photoreceiver. The laser emitter passes through the bubble water with a specific wavelength laser beam, and the receiver collects signals containing bubble concentration information based on the scattering, absorption, and reflection changes of the light beam in the water. To improve detection accuracy and applicability, multiple wavelengths of laser can be used, combined with the different absorption characteristics of different wavelengths for bubbles and water, to accurately distinguish the subtle changes in bubble particle size and concentration.

[0053] Optical detection units require stable optical path structures within the module, often equipped with waterproof protection and anti-reflection coatings to ensure long-term reliability. Meanwhile, to avoid interference from impurities or bubbles in the water flow, the sensor module can be designed to form a stable flow area within the water flow channel. This stable area is usually achieved by setting up flow straightening plates or turbulence buffering devices before and after the sensing area, ensuring constant flow velocity and uniform bubble distribution in the sensing area, thereby improving detection accuracy.

[0054] The data processing unit collects and analyzes signals from the photoreceiver in real time, using embedded processors or FPGA hardware accelerators for signal filtering, amplification, and normalization. Through built-in algorithms, the module can extract characteristic parameters representing bubble concentration from the collected signals, such as optical scattering intensity, signal periodicity, and spectral distribution. To improve robustness, the algorithm can be combined with machine learning techniques, trained with multiple bubble water samples before the module is shipped, to automatically adapt to complex detection environments under different water quality, gas types, and temperature conditions.

[0055] The signal output unit is responsible for transmitting the processed concentration information in the form of digital or analog signals to the control processing unit 105. To ensure the stability and real-time nature 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 such as Bluetooth or Wi-Fi according to requirements, to facilitate flexible arrangement and remote monitoring of the module. Signal output can include real-time concentration values, bubble distribution information, and device operating status, such as optical path contamination alarms or sensor failure alerts.

[0056] The installation location of the concentration sensor module is also crucial in system design, usually located in the area after the gas and water have fully mixed in the water flow channel. This location ensures that the sensor module monitors the most representative bubble concentration, while avoiding detection bias caused by incomplete bubble formation or excessive decomposition. The physical installation method of the module usually adopts buckle type, embedded type, or flange connection, combined with sealing structure, to ensure the stability and safety of the module under high pressure or high flow rate conditions.

[0057] The concentration sensor module can be combined with other types of sensing technology, such as acoustic sensing technology or electrochemical sensing technology, to form a multi-modal detection structure. Acoustic sensing technology uses ultrasonic wave attenuation and reflection characteristics when propagating in bubble water, which can complement optical detection technology and improve detection capability for 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] To meet the individual needs of different users for bubble concentration, the concentration sensing module can also be pre-set with multiple detection sensitivity modes, such as a high sensitivity mode for accurate detection of fine 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 operating state.

[0059] In summary, the concentration sensing module 103 in the 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 intelligent bubble concentration regulation.

[0060] The pressure regulation module 104 is configured in the gas supply path of the gas injection module and is used to detect and regulate the pressure of gas injection to maintain stable bubble size and distribution during the bubble generation process.

[0061] The pressure regulation module 104 is a key component in the system that ensures 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 size, distribution, and dissolution efficiency of the bubbles. Precise regulation of gas pressure not only affects the uniformity of bubble generation, but also directly determines the stability of the bubbles and their residence time in water.

[0062] The pressure regulation module is composed 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 fast response and generate an electric signal proportional to the pressure value in a high-pressure environment. To enhance its adaptability, the sensor's working range can cover a variety of gas pressure conditions, from low pressure (such as a few thousand pascals) to high pressure (such as several megapascals), ensuring efficient operation of the device in different gas types and use environments.

[0063] The pressure regulating valve is the actuator of pressure control, which dynamically adjusts the flow area of the gas through the supply path according to the control signal, thereby changing the gas pressure. The regulating valve can be designed with proportional electromagnetic valves or servo-controlled valves, with precise opening adjustment function, and the response speed usually reaches milliseconds to ensure the real-time performance of pressure regulation. To further improve stability, a pressure buffer chamber can be designed inside the valve body to reduce the disturbance of gas flow rate changes on the regulation process.

[0064] The signal processing unit connects the pressure sensor with the control processing unit, receives the pressure signal and converts it into a standardized digital signal, while monitoring the fluctuations in the signal to eliminate noise. The signal processing unit embeds a pressure calibration algorithm that can dynamically adjust the offset value and gain parameters of the sensor output, ensuring the accuracy and consistency of pressure measurement. In addition, the unit can perform a short-term average calculation on the detected pressure data to filter out transient pressure fluctuations caused by gas flow fluctuations.

[0065] The control interface is responsible for data interaction 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, realizing closed-loop pressure regulation. The interface usually uses digital communication protocols such as Modbus or CAN bus to ensure the stability and real-time performance of data transmission. In more complex designs, the pressure regulation module can also communicate directly with the gas flow regulation module to achieve joint optimization of pressure and flow.

[0066] The design and layout of the pressure regulation module directly affect 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 pressure regulation can meet the real-time requirements of the system. In addition, to avoid the influence of external environmental changes on the performance of the module, the shell of the pressure regulation module is made of corrosion-resistant, air-tight 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 regulation module is reflected in many aspects. First, by adjusting the gas pressure, the module can control the gas flow rate into the water, thereby achieving precise control of bubble particle size. When the target bubble concentration of the system is high, the pressure regulation module will increase the gas injection pressure to ensure that the gas can be uniformly dispersed in the water within a short period of time; while in the low concentration mode, the module reduces the gas pressure to avoid excessive dispersion of gas leading to a decrease in dissolution efficiency. Second, the module can also maintain the stability of the pressure during bubble generation. The pressure of the gas supply bottle may gradually decrease due to the reduction of use, and the pressure regulation module can dynamically compensate for the pressure drop by adjusting the opening of the valve, thereby ensuring the consistency of bubble generation.

[0068] The pressure regulation 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 gas requires higher pressure to form uniform bubble distribution. The module can also dynamically optimize the pressure regulation strategy according to 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 decrease in dissolution efficiency.

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

[0070] Further, the pressure regulation module is specifically used for:

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

[0072] According to the comparison result, a pressure deviation signal is generated, and the gas injection pressure is dynamically adjusted in combination with the current gas flow information to optimize the particle size and distribution of the bubbles.

[0073] The role of the pressure regulation module in the intelligent bubble concentration regulation system of the bubble 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. Through integrated sensors and control algorithms, the module accurately coordinates the relationship between gas pressure and gas flow to meet the high requirements for bubble generation conditions during system operation.

[0074] The pressure regulation module first acquires the current pressure and gas flow in the gas supply path through a pressure sensor and a flow meter. The pressure sensor is installed in the supply path of the gas injection module and can convert the detected gas pressure into an electrical signal and transmit this signal to the processing unit of the pressure regulation 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 regulation module. These data constitute the core input information for the pressure regulation 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 according to the user's set bubble concentration requirement and liquid environment conditions. 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 regulation module combines the current flow information to dynamically adjust the gas injection pressure. 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 electromagnetic valve or a servo-controlled valve. The pressure regulating device quickly responds to the signal sent by the module by changing the resistance of the gas injection path or adjusting the opening of the valve to achieve precise pressure regulation.

[0077] While dynamically adjusting, the pressure regulation module also considers the coupling relationship between flow and pressure. Since gas flow directly affects the formation rate and particle size distribution of bubbles, the module analyzes the flow information simultaneously when adjusting the pressure. For example, when the gas flow is large, appropriately increasing the pressure can ensure the uniformity of bubble particle size; conversely, when the flow is small, reducing the pressure can prevent bubbles from being too concentrated or broken. In this process, the control logic of the module not only bases on the pressure deviation value, but also combines the dynamic change trend of gas flow to ensure the stability and accuracy of the regulation result.

[0078] In addition, the pressure regulation 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 compare it with the target pressure. If there is still a deviation after 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 regulation process, avoiding abnormal bubble generation caused by over-regulation or under-regulation.

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

[0080] The control processing unit 105 is in communication connection with the gas injection module, the water temperature regulation module, the concentration sensing module, and the pressure regulation module, 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 regulation module, and the pressure parameter of the pressure regulation module according to the concentration deviation value, dynamically correcting the bubble concentration and particle size; calculating the target bubble concentration based on a preset mode or user-defined setting.

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

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

[0083] The control processing unit first receives the concentration signals from the concentration sensing module, which contain the actual bubble concentration information of the current 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 closed-loop control algorithms, such as proportional-integral-derivative (PID) control or fuzzy control algorithms. These algorithms can dynamically adjust the flow parameters of the gas injection module, the output temperature of the water temperature regulation module, and the pressure value of the pressure regulation module, so as to realize real-time optimization of bubble concentration and particle size under the joint adjustment of multi-dimensional parameters.

[0084] The embedded software module in the control processing unit is composed of multiple sub-modules, including data acquisition module, parameter calculation module, regulation strategy module and 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 in combination with the user-set mode or target value. The regulation strategy module generates adjustment instructions according to 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 specific bubble concentration requirements through the user interaction unit, such as "high concentration mode" or "low concentration mode". The system will automatically adjust the working state of each module according to the preset optimal parameters. In the user-defined mode, the control processing unit allows users to manually set parameters such as bubble concentration, water temperature and gas pressure to meet the user's individual needs.

[0086] Another important function of the control processing unit is to implement the recording and analysis of 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 adjustment and compensate for possible errors by adjusting the weight parameters of the control algorithm, thereby achieving more accurate control.

[0087] To enhance the intelligent 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 according to the change of environmental 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 more accurate optimal drinking recommendations to the user.

[0088] The control processing unit is connected with the user interaction unit through the communication module, realizing the bidirectional information transmission between the user and the system. The user can view the current bubble water generation state, adjust the mode parameters, or receive drinking recommendations through the mobile terminal 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 the user can download the latest control algorithm and function module through the wireless communication module, thereby continuously improving the performance and applicability of the system.

[0089] To ensure the safety and reliability of system operation, the control processing unit designs multiple protection mechanisms. For example, when the concentration sensing module or other execution modules detect abnormal signals, the control processing unit can trigger the automatic protection mode, suspend system operation, and send an alarm to the user. At the same time, the control processing unit has built-in redundant data storage function to ensure that important data will not be lost in case of system power failure or failure.

[0090] Through close integration with various modules, the control processing unit plays the role of command center in the system, can flexibly coordinate the working state of multiple modules and efficiently execute complex control tasks. Through multi-dimensional parameter closed-loop control, intelligent control strategy, and user-friendly interaction design, it improves the quality of bubble water.

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

[0092] receiving the real-time bubble concentration signal C detected by the concentration sensing module current and comparing it with the target bubble concentration C target to generate a concentration deviation value ΔC = C target -C current ;

[0093] C target Target gas bubble concentration, unit: mol / L, set by user through user interaction unit; current Current gas bubble concentration detected by concentration sensing module in real time, unit: mol / L;

[0094] Calculate the new gas flow according to the following formula 1:

[0095]

[0096] Wherein, F gas，new New gas flow, unit: L / min, represents the adjusted gas injection speed;

[0097] F gas，old Current gas flow, unit: L / min, monitored by gas injection module;

[0098] k1, k2 are empirical optimization constants; k1 is the concentration deviation influence coefficient, recommended value is 0.5; k2 is the concentration change rate influence coefficient, recommended value is 0.1;

[0099] Concentration change rate, calculated by concentration sensing module through concentration change in a short time;

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

[0101]

[0102] Wherein, T water，new New water temperature, water temperature after dynamic adjustment;

[0103] T water，old Current water temperature;

[0104] ΔH is the enthalpy change, unit: J / mol, which describes the heat change when the gas is dissolved in water, which can be calculated by the following formula:

[0105]

[0106] Wherein, R is the gas constant; T is the average temperature; k H1 Henry's coefficient at temperature T1; k H2 Henry's coefficient at temperature T2;

[0107] For example, the k H of carbon dioxide at 298K is 45 mol / (L·P a ), and the k H at 308K is 18 mol / (L·Pa ), the solubility enthalpy change is calculated as follows:

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

[0109] 2. Calculate

[0110] 3. Substitute the empirical formula:

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

[0112] This result is close to the actual experimental value, which is sufficient to meet the needs of many engineering applications. In formula 2, ΔH can be estimated as -19.4.

[0113] k4, k5 are empirical optimization constants; k4 is the dissolution heat influence coefficient, and the recommended value is 1.0; k5 is the concentration deviation influence coefficient, and the recommended value is 0.1.

[0114] According to the following formula 3, the new gas pressure is calculated:

[0115]

[0116] Where, P gas，new is the new gas pressure, unit is P a , indicating the dynamically adjusted gas injection pressure;

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

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

[0119] k6, k7 are empirical optimization constants, and the recommended value of both is 0.1.

[0120] According to the new gas flow, the new water temperature and the new gas pressure, 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 are adjusted respectively.

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

[0122] The user interaction unit 106 is a key module in the system that directly interacts with the user, and undertakes multiple functions of information input, mode selection, and state feedback, providing an intuitive and convenient operation interface for the user, while significantly improving the system's ease of use and personalized experience. 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 over the running state of the bubble water machine.

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

[0124] In order to ensure that the needs of different users can be met, the user interaction unit designs multiple preset modes and custom functions. Preset modes such as "high concentration mode", "low concentration mode", or "child mode" are optimized according to different use scenarios, so that ordinary users can quickly generate the required bubble water without deep technical details. And custom functions allow advanced users to manually input target concentration, water temperature, and pressure parameters, and view the system's response in real time through the interface, meeting more personalized needs.

[0125] This module also integrates a state feedback function, which shows the system running status to the user in real time. For example, when the control processing unit detects that the concentration deviation value exceeds the normal range, the user interface will pop up a warning message, prompting the user to adjust the parameters or check the equipment. At the same time, the user interaction unit will display the working state of the concentration sensing module and the pressure control module, helping the user to intuitively understand the health status of the equipment. If a fault is detected or maintenance is needed, 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] To enhance user experience, the user interaction unit not only focuses on functionality, but also pays attention to visual and operational aesthetics and smoothness. The interface design of the touch panel and mobile application adopts a modular layout, with each functional area carefully optimized to ensure clear information hierarchy and 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 are highlighted through pop-up windows or high-light effects to attract the user's attention.

[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 at appropriate times. 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. At the same time, combined with the data provided by the bubble retention time evaluation module 108, the user interaction unit can display real-time optimal drinking recommendations, such as "current sparkling water is suitable for drinking" and "bubble concentration will decrease soon, please drink as soon as possible."

[0128] In the design of modern smart home appliances, remote control and cloud connection are important development directions, and the user interaction unit fully embodies this trend. Through the cloud connection function of the mobile application, users can not only remotely monitor the device's running status, but also receive device firmware updates and optimization plans. System updates may include new preset modes, algorithm optimization, or interface improvements, which 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 device's running data to the cloud to generate long-term use reports or personalized service recommendations.

[0129] The hardware part of the user interaction unit is designed to be durable and environmentally friendly. For example, the touch panel is designed to be waterproof and can work reliably in humid environments, and its screen material is treated to be scratch-resistant, extending the service life of the device. The communication module of the mobile application adopts a low-power design to ensure that long-term connection does not cause excessive battery consumption to the user's device.

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

[0131] Further, the user interaction unit includes a touch panel configured to display detailed state 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 users can view detailed information by expanding the menu step by step through touch operations, while supporting the adjustment of 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 configured to support remote real-time control and state monitoring functions, wherein users can remotely set the target concentration, temperature, and pressure of the bubble water through the mobile application, while receiving push notifications of real-time generation status, including the current bubble concentration, water temperature, pressure, and optimal drinking time recommendation of the bubble water, and the application can automatically recommend generation parameters according to user preference history to optimize user experience.

[0133] The user interaction unit provides a brand-new multi-dimensional interaction method, combining touch panels and mobile applications, significantly improving user control ability and use experience of the bubble water machine. Touch panels and mobile applications each have unique functions, while realizing seamless connection between local operation and remote monitoring, meeting the diverse needs of users for personalized settings and real-time feedback.

[0134] The touch panel is designed as an embedded interface, directly integrated into the external operation area of the bubble water machine, through which users can conveniently view detailed state information of bubble water generation. The touch panel adopts a multi-level menu design, which can expand detailed data step by step 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, and when they need to understand in depth, they can further expand to view real-time change trends, historical data, and system analysis results of each parameter through touch gestures. The sensitivity and intuitiveness of touch operations enable users to quickly grasp the running status of the system, while conveniently adjusting the settings.

[0135] To realize precise and personalized control, the touch panel supports various gesture operations such as sliding and clicking. For example, users can adjust the target value of bubble concentration by sliding, and click to switch the set range of water temperature and pressure. All adjustments will take effect in real time, and the touch panel display area will be updated synchronously with the predicted effects after parameter changes, such as adjusted bubble retention time and water saturation state. This immediate feedback function not only enhances the interaction of operations, but also enables users to optimize parameter settings according to real-time display results, ensuring that the quality of bubble water meets expectations.

[0136] The mobile application further expands the operating range of the system, providing remote control and state monitoring functions through smart devices. Users can set the target concentration, water temperature, and pressure parameters of the sparkling water at any time and place through the application without directly touching the machine body. The mobile application also supports push notification functions. During the generation of sparkling water, users can receive real-time updates on the current bubble concentration, water temperature, pressure, and bubble retention time. The pushed notifications not only include current state data but also contain 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 when not near the device.

[0137] Notably, the mobile application not only supports real-time control and monitoring but also has user preference analysis and intelligent recommendation functions. The system records users' historical setting parameters, such as commonly used bubble concentrations, water temperature ranges, and preferred bubble retention times, and generates personalized recommendations based on these data through built-in algorithms. For example, if a user often chooses a certain bubble concentration and specific water temperature, the system will actively recommend the same parameter settings in similar future usage scenarios, reducing user adjustment time and improving operational convenience. This optimization design based on user behavior analysis significantly enhances the intelligence level of the system and user stickiness.

[0138] The combination of the touch panel and the mobile application not only embodies the comprehensiveness of the user interaction unit in terms of function 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 trends of modern intelligent devices, greatly improving user operation satisfaction and the market competitiveness of the system.

[0139] Furthermore, the user interaction unit includes a voice interaction module for receiving user voice commands through natural language processing technology and adjusting bubble concentration, water temperature, and pressure parameters according to the commands, while providing voice feedback information on the generated state, including current bubble concentration, pressure adjustment progress, and predicted bubble retention time. The voice interaction module supports multi-language recognition and personalized voice command settings to enhance the user's touchless control experience.

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

[0141] The core function of the voice interaction module is to receive user voice instructions and analyze their content. The module is built-in with a high-precision voice recognition engine, which can accurately capture user voice input, even in noisy environments, and improve the accuracy of voice recognition through noise reduction algorithms. Users can directly issue instructions through natural language, such as "increase the bubble concentration a little" "set the water temperature to ten degrees" "reduce the gas pressure", etc. The voice interaction module can quickly analyze the specific meaning of the instructions and extract the target parameters. The parsed instructions are passed to the control processing unit to drive the relevant modules (such as the 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 real-time voice feedback function. When the system completes the instruction adjustment or is executing the adjustment, the module will generate corresponding voice broadcast information. For example, after the user issues an instruction 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 requires 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 is clear and accurate, ensuring that the user always understands the running 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 Chinese local dialect, the module can support recognition and broadcast in different languages through the expansion and dynamic update of the language library. In addition, the module allows users to personalize voice instructions. For example, users can define short voice instructions for common operations, such as "regular settings" or "cold water mode", and the system will quickly execute a series of parameter adjustments according to the pre-defined mapping relationship, without the need to input specific instructions one by one each time.

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

[0145] By introducing natural language processing technology, multi-language support and personalized setting functions, the voice interaction module greatly improves the intelligent level of user interaction, making the bubble water machine intelligent bubble concentration control system not only meet the traditional parameter adjustment needs, but also provide services in a more user-friendly way. This non-contact, intuitive and efficient interaction mode lays a solid foundation for the expansion of the application scenarios of the system and the improvement of user satisfaction.

[0146] The communication module 107 is in communication connection with the control processing unit and the user interaction unit, and is used to realize remote operation and state feedback of the system.

[0147] The communication module 107 is the core bridge connecting the control processing unit and the user interaction unit in the system, and its function is to realize the bidirectional transmission and real-time feedback of data, so as to ensure the efficient operation of the intelligent bubble concentration control system of the bubble water machine and the improvement of user experience. The design of the communication module considers the diversified needs of modern intelligent devices, including stability, real-time, security and adaptability, so as to ensure that users can easily control the device and obtain system state information through remote or local ways.

[0148] The communication module supports multiple communication methods to meet the needs of different use 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) technology. Wi-Fi communication is suitable for scenarios that require remote control, such as users who want to start or adjust the running state of the bubble water machine remotely through mobile applications outside the home; Bluetooth is suitable for short-distance fast connection and local control, such as immediate setting and feedback when users operate the device in the kitchen. Low-power Bluetooth significantly reduces energy consumption while maintaining a longer connection time, making it very suitable for scenarios that require continuous monitoring of device operation. 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 is composed of a communication chip, an antenna, a signal processing unit and a power management unit. The communication chip is the core of the module, responsible for signal sending and receiving. The chip usually chooses high-performance, low-power models, such as chips supporting 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, ensuring stable connection of the device in different positions. The signal processing unit decodes, filters and corrects data to ensure the integrity and accuracy of transmitted data.

[0150] The communication module interacts with the control processing unit and the user interaction unit through standardized protocols. Common communication protocols include MQTT, HTTP, Modbus and custom binary protocols. MQTT protocol is suitable for transmitting real-time state data and control instructions due to its lightweight and high efficiency; HTTP protocol can be used for remote access of mobile applications, and secure HTTPS encryption channel is used to realize bidirectional transmission of data; 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 identity verification mechanisms to ensure the security of the system's communication. Data encryption uses the AES-256 standard to protect user settings, device status, and other sensitive information from being leaked or tampered with during transmission. Identity verification is achieved through the OAuth 2.0 protocol or similar authentication methods, limiting unauthorized access and preventing devices from being improperly controlled or interfered with.

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

[0153] In actual operation, the communication module provides strong support for the system's intelligence. For example, when the user sets the target bubble concentration through the mobile terminal application, the communication module will quickly transmit the instructions to the control processing unit, triggering the corresponding control process. At the same time, the communication module will transmit real-time concentration, gas flow, water temperature, and bubble retention time, and other key state information back to the user interaction unit, allowing the user to view at any time. In remote operation scenarios, users can start the device, modify parameters, or receive device operation reports through mobile devices, even if they are far away, they can still fully control the system.

[0154] To further enhance user experience, the communication module supports remote firmware updates (OTA). Users can push update packages through the cloud, and the communication module will automatically download and install the new version of software after receiving the update instructions, ensuring that the device always maintains the latest functions and optimal performance. In addition, the communication module can upload device operation data to the cloud upon user authorization, generating long-term operation reports or optimizing device control algorithms.

[0155] The design of the communication module also fully considers future scalability. For example, it can be compatible with home Internet of Things platforms, integrating with smart home systems to achieve voice control or scene linkage. Users can start the device or select specific modes through simple voice commands, and link the operation status of the bubble water machine with other home appliances (such as smart refrigerators or air purifiers), creating a more intelligent home experience.

[0156] Through close integration with the control processing unit and 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 guarantees, state monitoring, adaptive adjustment, and scalability design.

[0157] The bubble retention time evaluation module 108 is used to predict the bubble retention time of the sparkling water based on the real-time signals of the concentration sensing module and the calculations of the control processing unit, and to provide the user with optimal drinking recommendations through the user interaction unit.

[0158] The bubble retention time evaluation module 108 is an important component of the system, its main function is to predict the retention time of bubbles in sparkling water based on the real-time bubble concentration signals provided by the concentration sensing module and the dynamic calculations of the control processing unit, and to provide the user with optimized drinking recommendations accordingly. The design of this module aims to improve the user's subjective perception of the quality of sparkling water, while maximizing the drinking value of sparkling water, so that users can enjoy their drinks in the best state of bubbles.

[0159] This module analyzes a variety of parameters such as bubble concentration, particle size distribution, water temperature and gas pressure in water, uses mathematical modeling and empirical formulas to calculate the stability and retention time of bubbles in water. Specifically, the retention time of bubbles is affected by many factors, for example, higher bubble concentration and small particle size bubbles often mean longer retention time, while higher water temperature may accelerate the dissipation of bubbles. The bubble retention time evaluation module quantifies these complex relationships into a dynamic prediction model, and the control processing unit outputs real-time results based on this model.

[0160] The core of the module is a multivariate calculation engine, which has built-in dynamic models of bubble physical behavior and parameter optimization algorithms. Based on real-time data such as the current bubble concentration value provided by the concentration sensing module, the gas injection pressure monitored by the pressure control module, and the water temperature parameters detected by the water temperature control module, the calculation engine dynamically updates the input variables of the model. Through multiple iterations of calculation, the module can accurately predict the retention time of bubbles under specific conditions. For example, when the user sets the target as high-concentration sparkling water, the evaluation module will calculate the optimal retention time range of bubbles under this condition based on the data provided by the system, and provide a prompt to the user.

[0161] In order to adapt to different user needs, the design of the module takes into account the diversity of drinking preferences. For example, some users may want bubbles to be more persistent, while others may prefer the explosive feeling of bubbles at the entrance. To this end, the bubble retention time evaluation module allows users to select preferences such as "high stability" or "strong impact" in the mobile app or touch panel, and the system will adjust the model parameters accordingly to predict the bubble retention time under different modes.

[0162] The calculation results of the 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 show the trend of bubble state change in a graphical way, including the decay curve of bubble concentration over time or the comparison chart under different conditions. This visualization design helps users intuitively understand the variation law of bubble residence time, so as to make optimal decisions in different use scenarios.

[0163] An important extension function of the bubble residence time evaluation module is the deep integration with the user interaction unit. Through real-time calculation and prediction, the module can actively prompt the drinking suggestion 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 according to real-time monitoring data. If the user wants to extend the residence time of the bubbles, the module will also provide optimization suggestions, such as reducing water temperature or increasing gas injection pressure.

[0164] In order to further improve the intelligent level of the module, 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 chooses to drink after the bubbles have significantly weakened several times, the system will adjust the threshold of the model according to this behavior, optimize the prediction results to be closer to the actual needs of the user.

[0165] In terms of industrial design, the bubble residence time evaluation module balances performance and energy consumption through efficient hardware and software combination. The hardware part of the module uses embedded microprocessors, which can run complex calculation tasks with low power consumption. The software part reduces redundant calculations through algorithm optimization to ensure real-time response capability under multiple parameter conditions. The module also designs a self-learning function, which continuously iterates and optimizes the calculation model to improve prediction accuracy and system adaptability.

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

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

[0168] Further, the bubble residence time evaluation module is specifically used for:

[0169] The bubble residence time T of the bubble water is predicted according to Formula 4 as follows bubble :

[0170]

[0171] where ΔH is the enthalpy change of dissolution; 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 the current conditions; C current is the concentration of the gas in the current bubble water; v flow is the liquid convection intensity; v crit is the critical flow velocity; a 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 residence time evaluation module of the embodiment is used to predict the bubble residence time T of the bubble water generated bubble . The residence time is calculated by Formula 4, and the goal is to accurately estimate the life cycle of the bubble from generation to dissipation according to the physical and chemical properties of bubble dissolution and the liquid flow environment.

[0173] The formula is:

[0174]

[0175] The formula is composed of multiple parts, which respectively reflect the comprehensive influence of dissolution thermodynamics, mass transfer kinetics, liquid convection, temperature and pressure, etc. on the bubble residence time.

[0176] First, ΔH is the enthalpy change of dissolution, with the unit of J / mol. It represents the energy change when the gas is dissolved in the liquid, which is the key driving force for the dissolution rate of the gas. For carbon dioxide, the typical value is -19.4 kJ / mol, which can be consulted from a chemical handbook or determined by experiment. ΔH in Formula 4 can be calculated using -19.4.

[0177] k mass is the gas mass transfer coefficient, with the unit of m / s. It describes the speed of the gas diffusing from the bubble surface to the liquid, which depends on the viscosity of the liquid, temperature and the properties of the gas. The typical value is 0.001 m / s, which can be calibrated by experiment in the system. Increasing the stirring or convection intensity of the liquid will increase the value of k mass .

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

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

[0180] A = k A · F gas

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

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

[0183] C sat = k H · P gas

[0184] where k H is the Henry's coefficient, in mol / (L·P a ), with a typical value of 29.4 mol / (L·P a ) (for carbon dioxide); P gas is the current gas pressure, detected by the pressure sensing module.

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

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

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

[0188] The critical flow rate v crit is an experimentally calibrated value, with a recommended value of 0.01 m / s. This term reflects the property that at higher convection intensities, the bubble is more likely to escape the liquid surface.

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