Description

Technical Field

[0001] This invention relates to the field of gas regulation technology, and in particular to a multifunctional intelligent gas mixing and regulating integrated machine and its regulation and control method. Background Technology

[0002] Currently, hydrogen and oxygen regulating devices are being used more and more widely in home health and wellness, clinical rehabilitation, beauty and wellness, and consumer applications. In existing technologies, hydrogen and oxygen generators typically use water electrolysis to simultaneously produce hydrogen and oxygen, and for safety reasons, the proportion of the mixed gas is limited to a low level (e.g., hydrogen volume concentration not exceeding 4%) to avoid the risk of hydrogen explosion.

[0003] However, such devices can only provide hydrogen and oxygen, offering limited functionality. They cannot flexibly adjust the type, ratio, and flow rate of the output gas according to the user's individual needs, such as health status, age, physical condition, and usage scenario. Furthermore, it is difficult to achieve high-concentration hydrogen usage under safe and controllable conditions. More importantly, existing technologies generally lack negative ion generation capabilities, preventing the synergistic output of hydrogen, oxygen, and negative ions, which significantly limits the device's application scenarios and effectiveness. Summary of the Invention

[0004] The main objective of this invention is to propose a multifunctional intelligent gas mixing and regulating integrated machine and its regulating and control method, which aims to integrate three functions: hydrogen, preset gas and negative oxygen ions, and adaptively adjust the proportion and flow rate of the output gas according to the user's physiological parameters or external commands, thereby improving the intelligence and flexibility of the equipment.

[0005] To achieve the above objectives, the present invention proposes a multifunctional intelligent gas mixing and regulating integrated machine, comprising: chassis; A gas generation module, installed inside the housing, is used to generate a preset gas; An electrolysis hydrogen production module, installed inside the housing, is used to produce hydrogen. A negative oxygen ion generating module is installed inside the housing to generate an oxygen flow rich in negative oxygen ions. A mixing pipeline, connected to the output terminals of the gas generation module, the electrolytic hydrogen generation module, and the negative oxygen ion generating module, is used to mix preset gas, hydrogen, and negative oxygen ions as needed and output them to the user's nasal spray or face mask; and The main control unit is installed inside the housing and is electrically connected to the electrolytic hydrogen production module, the gas production module and the negative oxygen ion generating module respectively. The main control unit is used to electrically connect with external physiological monitoring equipment. When the user's physiological parameters collected by the external physiological monitoring equipment meet the preset conditions, it controls the gas generation module, the electrolytic hydrogen generation module and the negative oxygen ion generation module to output hydrogen, preset gas or airflow rich in negative oxygen ions in a corresponding proportion and flow rate according to the preset conditions. The external physiological monitoring equipment includes medical-grade monitoring equipment and consumer-grade wearable devices.

[0006] In one embodiment, the output end of the gas generating module is provided with a preset gas output branch, and the negative oxygen ion generating module is connected in series on the preset gas output branch to form physical isolation from the output end of the electrolytic hydrogen generating module. In one embodiment, a preset gas ratio regulating valve is provided on the preset gas output branch, and the output end of the preset gas ratio regulating valve is connected to the negative oxygen ion generating module; the output end of the electrolytic hydrogen production module is provided with a hydrogen ratio regulating valve. The multifunctional gas mixing intelligent regulation integrated machine also includes: An end regulating valve, the input end of which is connected to the output port of the mixing pipeline, and the output end of which is used to connect to a breathing mask; A hydrogen flow sensor is installed at the inlet of the mixing pipeline and electrically connected to the main control unit to detect the hydrogen flow rate before the mixing pipeline in real time. A preset gas flow sensor is installed at the inlet of the mixing pipeline and electrically connected to the main control unit to detect the preset gas flow rate before the mixing pipeline in real time. The main control unit is also used to adjust the opening degree of the hydrogen proportional regulating valve and the preset gas proportional regulating valve according to the feedback signals of the hydrogen flow sensor and the preset gas flow sensor, so as to control the output gas flow rate in a closed loop.

[0007] In one embodiment, the multifunctional gas mixing intelligent regulating integrated machine further includes a multi-gas path switching module installed in the housing. The multi-gas path switching module is electrically connected to the main control unit. The multi-gas path switching module has three input ports and one output port. The first input port is connected to the output terminal of the electrolytic hydrogen production module; the second input port is connected to the output terminal of the gas production module; the third input port is connected to the output terminal of the negative oxygen ion generating module; and the output port is used to connect to an end regulating valve or a breathing mask. The main control unit is also used to control the opening and closing of the three input ports and one output port of the multi-gas path switching module to achieve at least one of the following output modes: pure hydrogen mode, pure preset gas mode, pure negative oxygen ion mode, hydrogen and preset gas mixed mode, and hydrogen-oxygen negative ion mixed mode. The multi-functional gas mixing intelligent regulation integrated machine also includes a multi-dimensional safety monitoring module, which includes: An ambient hydrogen concentration sensor is mounted on the housing and electrically connected to the main control unit to detect the hydrogen concentration in the air surrounding the equipment. An infrared wear detection sensor is installed on the breathing mask and electrically connected to the main control unit to detect whether the mask is worn tightly against the user's face. A pipeline pressure sensor, located at the end of the mixing pipeline and electrically connected to the main control unit, is used to detect the gas pressure within the mixing pipeline; and An electrostatic detection unit is located at the end of the mixing pipeline and is spaced apart from the pipeline pressure sensor. The electrostatic detection unit is electrically connected to the main control unit and is used to detect electrostatic accumulation. The multidimensional safety monitoring module also includes a quick-release valve located at the end of the mixing pipeline, which is used to discharge the mixed gas to the outside or the catalytic hydrogen eliminator in case of an abnormality.

[0008] In one embodiment, the negative oxygen ion generating module includes: A pure water storage bottle is disposed inside the housing and is used to store pure water; A high-pressure orifice plate nozzle, the high-pressure orifice plate nozzle having an air inlet and multiple air outlets connected to the air inlet, the air inlet being connected to the preset gas output branch, used to draw in pressurized preset gas from the air inlet and convert it into a high-speed jet that is discharged from the multiple air outlets; and An impact plate is positioned in front of the high-pressure orifice plate nozzle to receive the impact of a high-speed preset gas jet, so that the high-speed preset gas jet impacts the pure water surface or the impact plate, generating a preset gas flow rich in negative oxygen ions.

[0009] This invention also proposes a regulation and control method using the multifunctional gas mixing intelligent regulation integrated machine as described above, comprising the following steps: Acquire user physiological parameters collected by external physiological monitoring devices or receive doctor's prescription input; Based on the user's physiological parameters or doctor's prescription input, the opening of the hydrogen ratio regulating valve and the preset gas ratio regulating valve are adjusted in real time to control the mixed gas ratio. At the same time, the electrolysis current of the electrolysis hydrogen production module is adjusted in real time to control the hydrogen flow rate, the compressor power or speed of the gas production module is adjusted to control the preset gas flow rate, and the preset gas flow rate introduced into the negative oxygen ion generating module is adjusted to control the negative oxygen ion flow rate. The prepared hydrogen gas is mixed with a preset gas or a preset hydrogen gas stream rich in negative oxygen ions and then output to the user's nose or face mask.

[0010] In one embodiment, the steps of adjusting the electrolysis current of the electrolysis hydrogen production module in real time to control the hydrogen flow rate, adjusting the compressor power or speed of the gas production module to control the preset gas flow rate, and adjusting the preset gas flow rate introduced into the negative oxygen ion generating module to control the negative oxygen ion flow rate according to the user's physiological parameters or doctor's prescription input include: Based on the target total flow rate set by the user and the target hydrogen concentration determined by the user's physiological parameters or doctor's prescription, calculate the hydrogen demand flow rate, the preset gas demand flow rate, and the negative oxygen ion demand flow rate. Based on the hydrogen demand flow rate, the preset gas demand flow rate, and the negative oxygen ion demand flow rate, control signals are simultaneously sent to the hydrogen proportional regulating valve, the preset gas proportional regulating valve, the electrolytic hydrogen production module, the gas production module, and the negative oxygen ion generating module. The hydrogen proportional regulating valve and the preset gas proportional regulating valve operate to their corresponding opening degrees according to the control signal; the electrolysis hydrogen production module adjusts the electrolysis current according to the control signal to match the required hydrogen flow rate; the gas production module adjusts the compressor power or speed according to the control signal to match the required preset gas flow rate; and the negative oxygen ion generating module adjusts the preset gas flow rate introduced into the negative oxygen ion generating module according to the control signal.

[0011] In one embodiment, the main control unit employs a cascade PID control strategy to execute the following steps based on the user's physiological parameters or doctor's prescription input: real-time adjustment of the electrolysis current of the electrolysis hydrogen production module to control the hydrogen flow rate; adjustment of the compressor power or speed of the gas production module to control the preset gas flow rate; and adjustment of the preset gas flow rate into the negative oxygen ion generating module to control the negative oxygen ion flow rate. The cascade PID control strategy includes: The first PID loop is used to obtain the deviation value between the target preset gas flow rate and the actual preset gas flow rate, and adjust the opening of the preset gas proportional regulating valve according to the deviation value to stabilize the preset gas flow rate.

[0012] In one embodiment, the step of inputting the user's physiological parameters or doctor's prescription includes: Based on the user's physiological parameters or doctor's prescription input, determine the current working mode to be entered. The working modes include normal mode and high-hydrogen usage mode. When the user's physiological parameters meet the preset conditions or a doctor's prescription is received, the current working mode is determined to be the high-hydrogen usage mode; otherwise, the current working mode is determined to be the normal mode. The preset conditions include the blood oxygen saturation of the external physiological monitoring device being lower than a preset threshold and the abnormal heart rate lasting for more than a first preset duration.

[0013] In one embodiment, in the normal mode, according to the user-input instructions or preset program, the multi-gas switching module is controlled to selectively output at least one of the following modes: pure hydrogen mode, pure preset gas mode, pure negative oxygen ion mode, hydrogen and preset gas mixed mode, or all gas mixed mode; wherein, when the hydrogen and preset gas mixed mode or all gas mixed mode is selected, the hydrogen volume concentration in the output gas is limited to not exceeding a first preset concentration. When switching between different output modes, the main control unit first switches the output gas to a pure preset gas mode for transition buffering, and then switches to the target output mode after the proportional valve opening is adjusted to the appropriate position. When the user selects the pure hydrogen mode, the main control unit, after receiving the doctor's prescription input and confirming safety, controls the multi-gas switching module to output only hydrogen and activates the safety monitoring strategy.

[0014] In one embodiment, the operating mode further includes a security mode; During the process of mixing the prepared hydrogen with a preset gas or a preset gas stream rich in negative oxygen ions and outputting it to the user, at least one of the following safety parameters is monitored in real time: ambient hydrogen concentration, mask wearing status, pipeline pressure, static electricity accumulation, electrolytic cell temperature, pure water tank level, pure water quality, and casing tilt angle. When any safety parameter is detected to exceed the corresponding safety threshold, the current working mode is immediately interrupted and the system is forcibly switched to the safety mode. In the safety mode, the electrolysis current of the electrolysis hydrogen production module is turned off to stop the generation of hydrogen, the compressor power or speed of the gas production module is maintained, and the preset gas flow rate into the negative oxygen ion generating module is maintained to maintain the output of preset gas or preset gas rich in negative oxygen ions, and the quick release valve is opened to vent the residual hydrogen in the pipeline.

[0015] The technical solution of this invention integrates a gas production module, an electrolytic hydrogen production module, and a negative oxygen ion generating module, and sets up a mixing pipeline and a main control unit to achieve the coordinated preparation and mixed output of hydrogen, preset gas, and negative oxygen ions. Simultaneously, the main control unit adjusts in real time the opening degree of the hydrogen proportioning valve and the preset gas proportioning valve, the electrolysis current of the electrolytic hydrogen production module, the compressor power or speed of the gas production module, and the preset gas flow rate into the negative oxygen ion generating module based on user physiological parameters collected by external physiological monitoring equipment or external commands input by doctors. This allows for adaptive control of the type, proportion, and concentration of the output gas according to individual user needs. Therefore, this invention solves the technical problems of existing hydrogen-oxygen regulation equipment, such as limited functionality, lack of coordinated negative oxygen ion output, inability to dynamically adjust gas proportions based on physiological parameters or external commands, and difficulty in achieving low hydrogen concentration usage under safety limitations. It significantly improves the intelligence, flexibility, user experience, and safety of the equipment. Attached Figure Description

[0023] Traditional hydrogen and oxygen output devices have functional limitations, typically only providing hydrogen and preset gases, making it difficult to flexibly adjust the type, proportion, and flow rate of the output gas according to individual user differences. Furthermore, achieving high-concentration hydrogen use under safe and controllable conditions remains challenging, and they generally lack negative ion generation capabilities, limiting the overall output performance and application scope of the devices.

[0024] For this, please refer to Figure 1This application proposes a multifunctional gas mixing intelligent regulating integrated machine, including a housing, a gas generating module 10, an electrolytic hydrogen generating module 20, a negative oxygen ion generating module 30, a mixing pipeline 40, and a main control unit 50. The gas generating module 10 is installed inside the housing for preparing a preset gas; the electrolytic hydrogen generating module 20 is installed inside the housing for preparing hydrogen; the negative oxygen ion generating module 30 is installed inside the housing for generating a preset gas flow rich in negative oxygen ions; the mixing pipeline 40 is connected to the output terminals of the gas generating module 10, the electrolytic hydrogen generating module 20, and the negative oxygen ion generating module 30, and is used for... The device mixes a preset gas, hydrogen, and negative oxygen ions as needed and outputs them to the user's nasal spray or face mask. A main control unit 50 is installed inside the housing and is electrically connected to the electrolytic hydrogen generation module 20, the gas generation module 10, and the negative oxygen ion generation module 30. The main control unit 50 is used to connect to an external physiological monitoring device. When the user's physiological parameters collected by the external physiological monitoring device meet the preset conditions, the device controls the gas generation module 10, the electrolytic hydrogen generation module 20, and the negative oxygen ion generation module 30 to output hydrogen, the preset gas, or a stream of air rich in negative oxygen ions in a corresponding proportion and flow rate according to the preset conditions.

[0025] The housing refers to the external structure used to house and protect the internal functional modules. Its material and design can be selected according to the application environment and safety requirements of the equipment. The gas generation module 10 is a device that uses molecular sieve adsorption technology to separate a preset gas from the air. Its working principle is based on the difference in adsorption capacity of different gas molecules in the molecular sieve, thereby achieving the preparation of a high-purity preset gas. The electrolytic hydrogen generation module 20 is a device that generates hydrogen through the electrolysis of water. Its core components typically include an electrolytic cell, power supply, and water circulation system. It decomposes water into hydrogen and the preset gas through an electrochemical reaction. The negative oxygen ion generating module 30 is a device that generates a large number of negative oxygen ions by impacting the surface of water or a specific material with a high-speed airflow, causing water or air molecules to ionize. The negative oxygen ion generating module 30 uses purely physical impact throughout the process, producing no ozone, and belongs to the small-particle-size Tai Chi negative oxygen ion generation category. The mixing pipeline 40 refers to the pipeline system used to guide and mix different gas flows. Its design must ensure uniform gas mixing and smooth transmission, and it is usually made of corrosion-resistant materials. The main control unit 50 is the intelligent core of the multifunctional gas mixing intelligent regulation integrated machine. It typically consists of a microprocessor, memory, and input / output interfaces, and is responsible for receiving instructions, processing data, coordinating the work of various functional modules, and realizing automated control of the equipment. External physiological monitoring equipment refers to medical devices capable of collecting user physiological data in real time, such as pulse oximeters, heart rate monitors, and blood pressure monitors. This data can be used to assess the user's health status. User physiological parameters refer to vital sign data obtained through external physiological monitoring equipment, such as blood oxygen saturation, heart rate, respiratory rate, and blood pressure. These parameters reflect the user's real-time physiological state. Preset conditions refer to the logical judgment conditions pre-set in the main control unit 50. When the user's physiological parameters meet these conditions, specific control strategies or operating modes will be triggered.

[0026] This embodiment provides a multifunctional intelligent gas mixing and regulating integrated machine. The integrated machine has an internal casing to house various functional modules. This casing can be made of various materials, such as plastic, metal alloys, or composite materials, and its structural design can be integrally molded or modularly assembled to adapt to different production processes and maintenance needs. A gas generating module 10 is configured inside the casing for preparing a preset gas. This gas generating module 10 can be implemented using traditional pressure swing adsorption (PSA) technology, separating the preset gas from the air through alternating adsorption and desorption processes. The preset gas flow rate can be controlled by adjusting the operating frequency of the compressor or the switching cycle of the adsorption tower.

[0027] Specifically, the gas generation module 10 is a molecular sieve oxygen generation module, which includes a compressor, an air filter connected to the input end of the compressor, several molecular sieve towers connected to the output end of the compressor via a solenoid valve group, and an oxygen storage tank connected to the output end of the molecular sieve towers via a pipeline. The input end of the oxygen storage tank is equipped with a preset gas check valve, and the oxygen storage tank is equipped with a preset gas pressure sensor and a preset gas concentration sensor. The output end of the oxygen storage tank is sequentially connected to a preset gas safety valve and a preset gas proportional regulating valve 60 to ensure a stable pressure for the output preset gas. The compressor controls the preset gas flow rate by adjusting its power or speed, and the solenoid valve group controls the alternating adsorption and desorption of the molecular sieve towers, thereby achieving continuous oxygen supply. The preset gas proportional regulating valve 60 is an electronically controlled proportional valve that receives instructions from the main control unit 50 to precisely regulate the preset gas output flow rate. In other embodiments, the gas generation module 10 can also be a module for preparing filtered and purified compressed air, oxygen-enriched air, and oxygen, and the preset gas can be any of these three types of gases.

[0028] Simultaneously, an electrolytic hydrogen production module 20 is also installed inside the casing for producing hydrogen. This electrolytic hydrogen production module 20 can use alkaline water electrolysis or proton exchange membrane water electrolysis technology to produce hydrogen by electrolyzing pure water. The flow rate of hydrogen can be controlled by adjusting the magnitude of the electrolysis current. The electrolytic hydrogen production module 20 includes an electrolytic cell, a pure water tank mounted on the upper side of the electrolytic cell via a water tank mounting plate, and a hydrogen-water separator. The pure water tank is connected to the electrolytic cell via a pure water pipeline for supplying pure water to the electrolytic cell. The electrolytic cell is equipped with an SPE membrane, a sintered electrolytic positive electrode, and a sintered electrolytic negative electrode. The SPE membrane divides the cell into a hydrogen chamber and a preset gas chamber. The hydrogen chamber is connected to the hydrogen-water separator via a pipeline, and the hydrogen-water separator is connected to a hydrogen storage tank via a hydrogen pipeline. A hydrogen one-way valve is installed at the input end of the hydrogen storage tank, and a hydrogen pressure sensor is installed on the hydrogen storage tank. The output end of the hydrogen storage tank is sequentially connected to a hydrogen safety valve and a hydrogen pressure regulating valve to ensure that the output hydrogen has the same pressure as the preset gas. The electrolysis current of the electrolyzer is controlled by the main control unit 50 to regulate the hydrogen flow rate. An electronically controlled hydrogen proportional regulating valve 70 is also connected in series on the output pipeline of the hydrogen storage tank for precise control of the hydrogen output flow rate.

[0029] In addition, a negative ion generating module 30 is installed inside the casing to generate a preset gas flow rich in negative oxygen ions. This module can generate negative oxygen ions by directly introducing the preset gas flow into a container filled with pure water and using the energy generated when the bubbles burst to ionize the water molecules. The concentration of negative oxygen ions can be roughly controlled by adjusting the preset gas flow rate or the water surface impact intensity.

[0030] To mix and deliver the prepared hydrogen, preset gas, and negative oxygen ions to the user, the integrated machine has a mixing pipeline 40. The hydrogen, preset gas, and negative oxygen ions mix in the pipeline through natural diffusion or a simple Venturi effect, and are ultimately delivered to the user's nose or face mask through a single outlet. The main control unit 50 is electrically connected to the electrolytic hydrogen production module 20, the gas production module 10, and the negative oxygen ion generation module 30. This main control unit 50 can be an embedded controller that, through preset program logic, directly sends start, stop, or power adjustment commands to each module to achieve preliminary control of gas production. The main control unit 50 is also used for electrical connection to external physiological monitoring equipment. The external physiological monitoring equipment can transmit the collected user physiological parameters to the main control unit 50 via wired or wireless means. For example, serial communication or Bluetooth modules can be used for data transmission.

[0031] When the main control unit 50 receives user physiological parameters collected by external physiological monitoring equipment that meet preset conditions, it will control the gas generation module 10, the electrolytic hydrogen generation module 20, and the negative oxygen ion generation module 30 to output hydrogen, preset gas, or negative oxygen ion-rich gas flow in corresponding proportions and flow rates according to these preset conditions. For example, the preset conditions can be a simple threshold judgment. When the blood oxygen saturation is lower than a certain fixed value, the main control unit 50 will trigger a fixed preset gas output mode, or when the heart rate exceeds a certain fixed value, it will trigger a fixed hydrogen output mode. The adjustment of gas proportions and flow rates adopts a closed-loop control algorithm based on real-time feedback, such as cascade PID control, to achieve precise and dynamic adjustment of hydrogen flow rate, preset gas flow rate, and negative oxygen ion flow rate.

[0032] This embodiment provides a multifunctional intelligent gas mixing and regulating unit that integrates hydrogen, preset gas, and negative oxygen ion generation functions. Combined with the main control unit 50's intelligent judgment and control of user physiological parameters collected from external physiological monitoring equipment, it achieves flexible adjustment of the type, proportion, and flow rate of the output gas. Therefore, this unit can provide personalized gas usage plans based on the user's real-time health status, effectively solving the problem of traditional equipment having limited functionality and failing to meet diverse usage needs, significantly expanding the application scenarios and synergistic effects of the equipment.

[0033] Please see Figure 1 Furthermore, this application proposes that the output end of the gas generating module 10 is provided with a preset gas output branch 10a, and the negative oxygen ion generating module 30 is connected in series on the preset gas output branch 10a to form physical isolation from the output end of the electrolytic hydrogen generating module 20.

[0034] Specifically, the preset gas output branch 10a is a pipeline specifically designed to guide the preset gas generated by the gas generating module 10. It can be constructed from corrosion-resistant and pressure-resistant medical-grade tubing to ensure the purity and safety of the preset gas during delivery. The preset gas output branch 10a is designed to provide an independent and pure source of preset gas for the negative ion generating module 30, preventing mixing with other gases (such as hydrogen) before entering the module. The negative ion generating module 30 is connected in series with the preset gas output branch 10a. This series connection means that the preset gas from the gas generating module 10 first flows through the preset gas output branch 10a and then directly enters the negative ion generating module 30 for negative ionization. The negative ion-rich preset gas stream, after negative ionization, is then output from the module and finally merges into the mixing pipeline 40. This layout ensures that the negative ion generation process takes place in a pure oxygen environment, thereby optimizing the efficiency and quality of negative ion generation. This is to physically isolate the hydrogen from the output of the electrolytic hydrogen production module 20. Physical isolation means ensuring, through pipeline layout and connection methods, that the hydrogen produced by the electrolytic hydrogen production module 20 does not directly enter the negative oxygen ion generating module 30. For example, the preset gas output branch 10a and the output of the electrolytic hydrogen production module 20 maintain independent channels before converging into the mixing pipeline 40, and the negative oxygen ion generating module 30 only receives the preset gas from the preset gas output branch 10a. This isolation effectively prevents hydrogen from contacting the potentially humid environment or high-voltage electric field inside the negative oxygen ion generating module 30, thereby significantly reducing the potential risk of explosion or equipment damage.

[0035] Please see Figure 2 and Figure 3 This application further proposes that a preset gas proportion regulating valve 60 is provided on the preset gas output branch 10a, and the output end of the preset gas proportion regulating valve 60 is connected to the negative oxygen ion generating module 30; at the same time, a hydrogen proportion regulating valve 70 is provided at the output end of the electrolytic hydrogen production module 20.

[0036] The preset gas proportional regulating valve 60 is a device for precisely controlling the preset gas flow rate. It can be implemented in various forms; for example, it can be an electromagnetic proportional valve that receives electrical signals from the main control unit 50 to precisely adjust its opening, thereby achieving stepless regulation of the preset gas flow rate. This valve is installed on the preset gas output branch 10a, and its output end is connected to the negative oxygen ion generating module 30. This means that the preset gas flow rate entering the negative oxygen ion generating module 30 and the preset gas flow rate in the subsequent mixing pipeline 40 can both be precisely controlled by this valve. The hydrogen proportional regulating valve 70 is a device for precisely controlling the hydrogen flow rate. Similar to the preset gas proportional regulating valve 60, it can also be implemented as an electromagnetic proportional valve or a mass flow controller to ensure the precise controllability of the hydrogen flow rate. Considering the flammability of hydrogen, the valve is designed and selected with special attention to explosion-proof and sealing performance. This valve is installed at the output end of the electrolytic hydrogen production module 20 and is used to directly regulate the hydrogen flow rate output from the electrolytic hydrogen production module 20, thereby controlling the hydrogen concentration in the mixed gas.

[0037] Through the above technical solution, a preset gas proportioning valve 60 is installed on the preset gas output branch 10a of the gas generation module 10, and a hydrogen proportioning valve 70 is installed at the output end of the electrolytic hydrogen generation module 20. This allows the main control unit 50 to independently and precisely adjust the output flow rates of hydrogen and the preset gas. This solves the problem of inaccurate gas proportioning control in traditional solutions, achieving refined and dynamic control of the mixed gas ratio. The main control unit 50 can adjust the opening of these two proportioning valves according to the user's physiological parameters or the doctor's prescription to change the volume concentration of hydrogen and the preset gas in the output gas in real time, thereby providing a personalized usage plan. In addition, since the preset gas proportioning valve 60 is located before the negative oxygen ion generating module 30, its opening adjustment also indirectly controls the flow rate of the preset gas entering this module, thereby affecting the generation and concentration of negative oxygen ions, and enabling effective regulation of the negative oxygen ion concentration. This precise flow control mechanism not only improves the usability and safety of the intelligent regulating integrated machine, but also provides a hardware foundation for subsequent more complex intelligent control strategies.

[0038] This application further proposes an improvement scheme, please refer to [link / reference needed]. Figure 1 and Figure 2The multi-functional gas mixing intelligent regulating unit also includes an end regulating valve 80, a hydrogen flow sensor 90, and a preset gas flow sensor 100. The input end of the end regulating valve 80 is connected to the output port of the mixing pipeline 40, and its output end is used to connect to a breathing mask. The hydrogen flow sensor 90 is located at the inlet of the mixing pipeline 40 and is electrically connected to the main control unit 50 to detect the hydrogen flow rate before the mixing pipeline in real time. The preset gas flow sensor 100 is also located at the inlet of the mixing pipeline 40 and is electrically connected to the main control unit 50 to detect the preset gas flow rate before the mixing pipeline in real time. The main control unit 50 is also used to adjust the opening of the hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60 based on the feedback signals from the hydrogen flow sensor 90 and the preset gas flow sensor 100, thereby controlling the output gas flow rate in a closed loop.

[0039] Specifically, the end regulating valve 80 is designed to provide a final mixing buffer space before the mixed gas is delivered to the user. Its function is to further homogenize the hydrogen, preset gas, and negative oxygen ions, ensuring thorough mixing of the gas components, thereby providing a more representative sample for subsequent concentration detection and stabilizing the gas output pressure. Specifically, the volume of the end regulating valve 80 is set to 100-500 ml, and it has an internal spiral baffle structure to promote uniform mixing of hydrogen and oxygen ions. More preferably, a hydrogen flow sensor 90 and a preset gas flow sensor 100 are installed at the inlet of the mixing pipeline 40 to monitor the actual hydrogen flow rate before the mixing pipeline in real time and provide feedback to the proportional valve. The hydrogen flow sensor 90 is used to monitor the flow rate of hydrogen from the mixing chamber at the inlet of the mixing pipeline 40 in real time and accurately. Its working principle can be based on electrochemical, thermal conductivity, or semiconductor technologies, quantifying the hydrogen content by detecting the interaction between hydrogen molecules and the sensing element. The sensor converts the detected hydrogen flow signal into an electrical signal and transmits it to the main control unit 50. It is installed at the inlet of the mixing line 40 to ensure that the detected flow rate is the actual hydrogen flow rate in the gas inhaled by the user.

[0040] Similar to the hydrogen flow sensor 90, the preset gas flow sensor 100 is used to monitor the flow rate of the preset gas before mixing in real time. It can operate using electrochemical, zirconium oxide, or paramagnetic principles, converting the detected preset gas concentration information into an electrical signal and feeding it back to the main control unit 50. Working in conjunction with the hydrogen flow sensor 90, the preset gas flow sensor 100 ensures comprehensive monitoring of the two main active components in the mixed gas, providing fundamental data for precise control.

[0041] After receiving real-time feedback signals from the hydrogen flow sensor 90 and the preset gas flow sensor 100, the main control unit 50 compares them with the preset hydrogen flow rate and preset gas flow rate. If a deviation exists, the main control unit 50 calculates the required adjustment amount according to a preset control algorithm (e.g., proportional-integral-derivative (PID) control algorithm) and adjusts the opening of the hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60 accordingly. This closed-loop control mechanism can dynamically compensate for changes in the internal or external environment of the system, ensuring that the concentration of the mixed gas output to the user end is always maintained at the target setpoint, thereby achieving accurate and stable gas delivery.

[0042] By installing a terminal regulating valve 80 at the output port of the mixing pipeline 40, and configuring a hydrogen flow sensor 90 and a preset gas flow sensor 100 to monitor the output gas in real time, the main control unit 50 can obtain data on the concentrations of hydrogen and preset gas in the gas actually inhaled by the user. Based on this, the main control unit 50 uses these feedback signals to perform closed-loop regulation of the hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60, thereby overcoming the problems of inaccurate concentration and instability that may exist in traditional open-loop control. This real-time feedback and dynamic adjustment mechanism ensures that the concentrations of hydrogen and preset gas delivered to the user always accurately meet the preset values ​​or doctor's prescription requirements, greatly improving the accuracy, safety, and reliability of use.

[0043] Optionally, the end regulating valve has a mixing chamber inside, and the mixing chamber is provided with a turbulence structure to promote uniform gas mixing.

[0044] This application further proposes, please refer to, Figure 3 and Figure 4 The multi-functional gas mixing intelligent regulating integrated machine also includes a multi-gas path switching module 110 installed inside the casing. This multi-gas path switching module 110 is electrically connected to the main control unit 50 and has three input ports and one output port. Specifically, the first input port is connected to the output terminal of the electrolytic hydrogen production module 20; the second input port is connected to the output terminal of the gas production module 10; and the third input port is connected to the output terminal of the negative oxygen ion generating module 30. The output port is used to connect to the end regulating valve 80 or a breathing mask. The main control unit 50 is also used to control the opening and closing of the three input ports and one output port of the multi-gas path switching module 110 to achieve at least one of the following output modes: pure hydrogen mode, pure preset gas mode, pure negative oxygen ion mode, hydrogen and preset gas mixing mode, and all gas mixing mode.

[0045] Specifically, the multi-gas-path switching module 110 is a device for selectively connecting multiple gas input sources and a single gas output target. It can be implemented in various forms, such as an array of solenoid valves, rotary valves, or microfluidic valves. For example, by configuring a series of independently controllable solenoid valves, each corresponding to an input or output gas path, the main control unit 50 achieves selective conduction of different gases by precisely controlling the opening and closing combinations of these valves. Its core function is to provide a mechanism for physical isolation and selective connectivity, ensuring that the desired gas can be accurately and purely guided to the output end, while avoiding unnecessary gas cross-contamination or leakage. The three input ports and one output port of the multi-gas-path switching module 110 define its connection topology. The three input ports serve as independent inlets for hydrogen, a preset gas, and a negative oxygen ion flow, respectively, while the one output port collects and exits the selected gas. These interfaces are typically physically connected to the corresponding gas sources and output paths via standard pipe fittings, and their internal structure, through sophisticated valve or channel design, ensures that the input gas can be guided to the output port independently or in combination. The main control unit 50, as the core control component of the entire system, integrates a microprocessor, memory, and corresponding control algorithms. Upon receiving a user command or according to a preset program, the main control unit 50 sends precise electrical signals to the multi-gas switching module 110, driving its internal valves to open and close. For example, in pure hydrogen mode, the main control unit 50 will only open the valve connecting the output of the electrolysis hydrogen production module 20 to the output port of the multi-gas switching module 110, while closing valves of other gas sources, thus ensuring that only hydrogen is output. This intelligent control method gives the equipment high flexibility and adaptability, enabling it to provide customized gas delivery solutions according to different usage requirements.

[0046] Preferably, the multi-gas switching module 110 uses a direct-acting solenoid valve with a working voltage of 24V DC, a response time of ≤30ms, and a nominal diameter of DN3-DN8. Based on software interlocking, a one-way valve is connected in series in the pipeline before the preset gas inlet to prevent hydrogen from flowing back into the preset gas pipeline due to pressure fluctuations.

[0047] Through the aforementioned technical solution, this application introduces a multi-gas path switching module 110, intelligently controlled by the main control unit 50, enabling the integrated machine to move beyond a single mixing output mode. The device can selectively output pure hydrogen, pure preset gas, pure negative oxygen ions, or a mixture of hydrogen and preset gas, or a mixture of all gases, depending on actual needs. This greatly enhances the device's flexibility and functional versatility, solving the problem that traditional single mixing pipelines 40 struggle to independently output multiple single gases or specific gas combinations. Building upon the basic hydrogen, oxygen, and negative ion preparation and mixing functions, the addition of the multi-gas path switching module 110 allows the integrated machine to provide more precise and personalized gas delivery for different health conditions or usage scenarios. For example, pure hydrogen can be directly provided to patients requiring high concentrations of pure hydrogen; pure oxygen can be provided to patients requiring oxygen therapy; and pure negative oxygen ions can be provided for scenarios requiring improved air quality or auxiliary use. This mode-switching capability allows the device to adapt to a wider range of clinical, healthcare, or consumer-grade needs, improving its practical value and the targeted effectiveness of its use. Meanwhile, the precise control of the main control unit 50 ensures the smoothness and safety of switching between different modes, avoiding the risk of cross-contamination or improper mixing of gases.

[0048] Please see Figure 1 and Figure 2 The multi-functional gas mixing intelligent regulating integrated machine also includes a multi-dimensional safety monitoring module 120. This module aims to provide comprehensive safety assurance by integrating multiple sensors to monitor the equipment's operating environment, user status, and key parameters during gas delivery in real time. Its core function is to promptly detect potential safety hazards and report them to the main control unit 50 so that corresponding safety measures can be taken, thereby significantly improving the overall safety and reliability of the equipment.

[0049] Specifically, the multidimensional safety monitoring module 120 includes an ambient hydrogen concentration sensor 121, an infrared wear detection sensor 122, a pipeline pressure sensor 123, and an electrostatic detection unit 124.

[0050] An ambient hydrogen concentration sensor 121 is mounted on the housing and electrically connected to the main control unit 50, used to detect the hydrogen concentration in the air surrounding the equipment in real time. The sensor operates based on electrochemical reactions, catalytic combustion, or thermal conductivity principles, converting the ambient hydrogen concentration into an electrical signal. When the detected hydrogen concentration exceeds a preset safety threshold, the sensor immediately sends an alarm signal to the main control unit 50, indicating a possible hydrogen leak. This provides a basis for the main control unit 50 to take emergency shutdown and ventilation measures, effectively preventing the risk of explosion caused by hydrogen accumulation. In one specific embodiment, the ambient hydrogen concentration sensor 121 is a catalytic combustion type sensor with a range of 0-4% Vol (corresponding to 0-100% LEL lower explosive limit), an accuracy of ±0.1% Vol, and a response time T90 ≤ 15 seconds.

[0051] An infrared wear detection sensor 122 is mounted on the respirator and electrically connected to the main control unit 50 to detect whether the mask is tightly fitted to the user's face. This can be achieved using an infrared emitter and receiver pair, determining the wearing status by detecting the reflection or transmission of infrared light between the mask and the face. For example, when the mask fits tightly to the face, infrared light is blocked or the reflection pattern changes; when the mask is loose or not worn, the infrared light path changes significantly. Based on the signal from the sensor, the main control unit 50 can determine whether the user is using the mask correctly, ensuring that gas is effectively and safely delivered to the user, preventing gas leakage or aspiration. Specifically, the infrared wear detection sensor 122 is installed at the bridge of the nose or the cheek area of ​​the respirator and emits infrared light into the skin. When the infrared wear detection sensor 122 measures a distance ≤1mm, it is determined to be "tightly fitted"; when the distance is >2mm, it is determined to be "not worn / loose".

[0052] A pipeline pressure sensor 123 is located at the end of the mixing pipeline 40 and electrically connected to the main control unit 50 for real-time detection of gas pressure within the mixing pipeline 40. It can be of various types, such as piezoresistive, capacitive, or strain gauge, converting pressure changes within the pipeline into electrical signals. By continuously monitoring the pipeline pressure, the main control unit 50 can promptly detect problems such as pipeline blockage, leakage, or pumping abnormalities, preventing pipeline rupture due to excessive pressure or insufficient gas delivery due to insufficient pressure, thereby ensuring the stability and safety of gas delivery.

[0053] An electrostatic discharge (ESD) detection unit 124 is located at the end of the mixing pipeline 40 and spaced apart from the pipeline pressure sensor 123. The ESD detection unit 124 is electrically connected to the main control unit 50 and is used to detect static electricity accumulation. During gas transport, especially when dry gas flows at high speeds, ESD is easily generated, which may trigger spark discharge and pose a potential ignition risk to flammable gases (such as hydrogen). The ESD detection unit 124 can employ a non-contact ESD field sensor or a contact ESD voltage sensor to monitor the amount of static charge or voltage on the inner wall of the pipeline or in the gas flow in real time. When ESD accumulation reaches a dangerous level, the unit will issue an alarm to the main control unit 50, prompting the main control unit 50 to take measures (such as reducing the gas flow rate, activating the ESD elimination device, or suspending hydrogen output) to eliminate or reduce the ESD risk. Preferably, the ESD detection unit 124 uses a non-contact ESD voltage sensor (based on capacitive coupling principle) installed near the inner wall of the mixing valve. Its ESD voltage threshold is set to 3kV; exceeding this value triggers an alarm.

[0054] Through the above technical solution, this application introduces a multi-dimensional safety monitoring module 120 into the multi-functional gas mixing intelligent regulating integrated machine, significantly improving the safety of equipment operation. This module monitors the hydrogen concentration around the equipment in real time through an ambient hydrogen concentration sensor 121. Once an anomaly is detected, the main control unit 50 can respond promptly, effectively preventing potential dangers caused by hydrogen leakage. An infrared wear detection sensor 122 ensures the correct wearing of the breathing mask, avoiding gas leakage and ineffective delivery, ensuring that users can safely and effectively inhale the required gas. A pipeline pressure sensor 123 continuously monitors the gas pressure within the mixing pipeline 40, enabling timely detection and handling of pipeline anomalies, preventing safety hazards caused by pressure issues. Furthermore, an electrostatic detection unit 124 can monitor and warn of electrostatic accumulation in the pipeline in real time, effectively reducing the risk of hydrogen ignition due to electrostatic discharge.

[0055] Please see Figure 1 and Figure 2 This application further proposes that the multidimensional safety monitoring module 120 also includes a quick-release valve 125 disposed at the end of the mixing pipeline 40, the quick-release valve 125 being used to discharge the mixed gas to the outside or the catalytic hydrogen eliminator in case of an abnormality.

[0056] The quick-release valve 125 is a valve capable of rapidly opening to discharge or divert gas from the mixing pipeline 40. It is characterized by its fast response speed and is typically controlled by an electromagnetically driven or pneumatically driven valve via an electrical signal from the main control unit 50. When the main control unit 50 determines that venting is necessary, the quick-release valve 125 opens rapidly to discharge gas (especially hydrogen) from the mixing pipeline 40, thereby reducing pipeline pressure, preventing overpressure, and avoiding the accumulation of hazardous gases inside the equipment or in the user's environment. The quick-release valve 125 is usually located at the end of the mixing pipeline 40 to ensure effective discharge of the mixed gas to be delivered to the user. In one specific embodiment, the quick-release valve 125 is a normally closed direct-acting solenoid valve with a nominal diameter of DN8-DN10 and a response time ≤20ms. Its discharge port can be connected to the outdoors or a catalytic hydrogen removal unit.

[0057] An abnormal situation occurs when any of the sensors in the multi-dimensional safety monitoring module 120, such as the ambient hydrogen concentration sensor 121, the infrared wear detection sensor 122, the pipeline pressure sensor 123, and the electrostatic detection unit 124, detects a condition exceeding a preset safety threshold. Examples include excessive pressure in the mixing pipeline 40, excessive hydrogen concentration in the surrounding environment, excessive static electricity buildup, or a respirator falling off, preventing normal gas delivery. The main control unit 50 triggers the opening of the quick-release valve 125 based on these abnormal signals.

[0058] Venting the gas mixture outdoors is a direct and low-cost venting method. It involves guiding the mixture (especially hydrogen) to an open space through a dedicated exhaust pipe, allowing it to diffuse rapidly and reduce local concentration. This requires the exhaust outlet to be located away from ignition sources and densely populated areas to ensure safety. Venting the gas mixture to a catalytic hydrogen scavenger is an even safer venting method, particularly suitable for indoor environments or situations with extremely high safety requirements. Catalytic hydrogen scavengers are typically filled with a precious metal catalyst (such as platinum or palladium), which reacts hydrogen with a pre-selected gas in the air at room temperature to produce water, thus completely eliminating the flammability and explosiveness risks of hydrogen. This method ensures that the emitted gas is safe, avoiding the risks associated with direct hydrogen release.

[0059] Please see Figure 1 and Figure 3This application further proposes a negative oxygen ion generating module 30, including a pure water storage bottle 31, a high-pressure orifice nozzle 32, and an impact plate 33. The pure water storage bottle 31 is disposed within the housing and is used to store pure water. The high-pressure orifice nozzle 32 has an air inlet and multiple air outlets connected to the air inlet. The air inlet is connected to the preset gas output branch 10a, used to draw in pressurized preset gas from the air inlet and convert it into a high-speed jet that is discharged from the multiple air outlets. The impact plate 33 is disposed in front of the high-pressure orifice nozzle 32 and is used to receive the impact of the high-speed preset gas jet, so that the high-speed preset gas jet impacts the pure water surface or the impact plate 33, generating a preset gas flow rich in negative oxygen ions.

[0060] Specifically, the pure water storage bottle 31 is used to store pure water for the negative ion generation process. This pure water storage bottle 31 is typically made of corrosion-resistant, non-toxic materials, such as food-grade plastic or stainless steel, to ensure the purity of the stored water. It may contain a liquid level sensor electrically connected to the main control unit 50 for real-time monitoring of the water level. The sensor will issue an alarm or automatically replenish pure water when the water level is too low, ensuring the continuous and stable operation of the negative ion generating module. Furthermore, to prevent microbial growth, the pure water storage bottle 31 may be designed for easy cleaning or have an ultraviolet sterilization function.

[0061] The high-pressure orifice nozzle 32 is one of the core components of the negative ion generating module 30. Its function is to convert the pressurized preset gas from the preset gas output branch 10a into a high-speed jet. This nozzle is typically made of precision-machined corrosion-resistant materials, such as stainless steel or ceramic. Its inlet is connected to the preset gas output branch 10a, ensuring smooth entry of the preset gas. The nozzle's interior is designed with multiple micro-aperture outlet holes. When the pressurized preset gas passes through these micro-holes, it is accelerated by the pressure difference effect and the Venturi effect, forming a fine preset gas jet with extremely high kinetic energy. These high-speed jets are crucial for generating negative oxygen ions, as they will impact the surface of pure water or strike the plate 33, thereby triggering the splitting of water molecules and the release of electrons.

[0062] The impact plate 33 is positioned in front of the high-pressure orifice nozzle 32 to receive the impact of the high-speed preset gas jet. The impact plate 33 is typically made of wear-resistant and corrosion-resistant materials such as stainless steel, titanium alloy, or special ceramics. Its surface can be designed to be smooth, uneven, or have a specific texture to optimize the jet impact effect and maximize the contact area and impact intensity between water molecules and the preset gas jet. When the high-speed preset gas jet impacts the pure water surface or the impact plate 33, it generates intense shear force, cavitation effect, and triboelectric effect, causing water molecule clusters to break down and release electrons. These electrons are subsequently captured by oxygen molecules, thus forming negative oxygen ions. The position and angle of the impact plate 33 can be precisely adjusted according to actual needs to achieve the optimal negative oxygen ion generation efficiency and concentration.

[0063] In one specific embodiment, the orifice diameter of the high-pressure orifice plate nozzle 32 is set to 0.2-1.0 mm, and the number of orifices is set to 1-8 according to the total flow requirement. The material is 316L stainless steel or corrosion-resistant and wear-resistant material. The distance between the impact plate 33 and the nozzle is set to 5-20 mm, and the impact angle is preferably vertical 90° or inclined at an acute angle of 60°-75°. The volume of the pure water storage bottle 31 is set to 200-1000 ml, and a capacitive liquid level sensor or a photoelectric liquid level sensor is installed inside. More preferably, an air ion concentration detector is installed at the air outlet of the negative oxygen ion generating module 30 to feed back the negative oxygen ion flow electrical signal to the main control unit 50 to form a closed-loop control; at the same time, a baffle-type gas-water separator and a terminal medical water mist separator are installed at the upper part of the module air outlet to prevent water mist from entering the pipeline.

[0064] Through the above technical solution, this application provides a negative oxygen ion generating module 30 with a clear structure and well-defined working principle. The pure water storage bottle 31 ensures a pure water source for negative oxygen ion generation, avoiding the impact of impurities on the generation efficiency and purity. The high-pressure orifice nozzle 32 efficiently converts the preset gas into a high-speed jet, providing sufficient kinetic energy for negative oxygen ion generation. The impact plate 33, through a precise physical impact mechanism, causes water molecules to break down and release electrons, thereby forming a high concentration of negative oxygen ions. When this negative oxygen ion generating module 30 is connected in series with the preset gas output branch 10a of the gas generating module 10, it can utilize the preset gas generated by the oxygen generating module as a carrier gas and impact medium, stably and efficiently generating a preset gas flow rich in negative oxygen ions while physically isolating hydrogen. This not only improves the generation efficiency and purity of negative oxygen ions but also provides users with a safer and healthier oxygen-rich negative ion inhalation experience, effectively solving the problem of how to efficiently and stably utilize a preset gas flow to generate high-concentration negative oxygen ions while ensuring purity and safety.

[0065] Please see Figure 1 and Figure 5 The present invention also discloses a regulation and control method using a multifunctional gas mixing intelligent regulation integrated machine, comprising the following steps: S10: Acquire user physiological parameters collected by external physiological monitoring devices or receive doctor's prescription input; S20: Based on the user's physiological parameters or doctor's prescription input, adjust the opening of the hydrogen ratio regulating valve 70 and the preset gas ratio regulating valve 60 in real time to control the mixed gas ratio. At the same time, adjust the electrolysis current of the electrolysis hydrogen production module 20 in real time to control the hydrogen flow rate, adjust the compressor power or speed of the gas production module 10 to control the preset gas flow rate, and adjust the preset gas flow rate introduced into the negative oxygen ion generating module 30 to control the negative oxygen ion flow rate. S30: The prepared hydrogen gas is mixed with a preset gas or a preset hydrogen gas stream rich in negative oxygen ions and then output to the user's nose or face mask.

[0066] The core innovation of this embodiment lies in combining the dynamic feedback of user physiological parameters with the linkage adjustment of multi-module parameters in a closed-loop control manner. This breaks through the limitation of traditional equipment relying solely on fixed-ratio output, and achieves a technical path that accurately adapts to individualized usage needs within a safe threshold. This results in the effect of dynamically increasing the hydrogen concentration to the required level while simultaneously ensuring system safety.

[0067] Specifically, this regulation and control method first receives user physiological parameters such as blood oxygen saturation and heart rate transmitted from external physiological monitoring devices through the main control unit 50, or directly imports usage instructions entered by doctors' prescriptions. Based on the above parameters, the main control unit 50 performs multi-dimensional coordinated regulation: it dynamically adjusts the opening of the hydrogen proportion regulating valve 70 and the preset gas proportion regulating valve 60 in real time to ensure that the hydrogen-oxygen ratio in the mixed gas strictly conforms to the preset usage plan; it synchronously adjusts the electrolysis current intensity of the electrolysis hydrogen production module 20 to make the hydrogen flow rate accurately match the flow rate demand after the opening adjustment; it simultaneously controls the compressor power or speed of the gas production module 10 to ensure that the preset gas supply is consistent with the target ratio; in addition, it achieves gradient regulation of negative oxygen ion concentration by changing the oxygen flow rate introduced into the negative oxygen ion generating module 30.

[0068] For example, when an external physiological monitoring device detects that a user's blood oxygen saturation is below a preset threshold, the main control unit 50 can determine that the user is in a hypoxic state. At this time, it will prioritize increasing the opening of the preset gas proportion regulating valve 60 and correspondingly increase the compressor power of the gas generating module 10 to increase the preset gas output ratio, thereby quickly improving the blood oxygen level. When an abnormally high heart rate is detected, accompanied by abnormal inflammation-related indicators, the main control unit 50 can determine that the anti-inflammatory and antioxidant effects of hydrogen need to be utilized. At this time, it will gradually increase the opening of the hydrogen proportion regulating valve 70 and simultaneously increase the electrolysis current to make the hydrogen concentration exceed the conventional limit and enter the high-hydrogen usage mode. When a user is fatigued or in a sub-healthy state and needs to relax, the main control unit 50 can increase the preset gas flow rate into the negative oxygen ion generating module 30 to increase the concentration of negative oxygen ions, thereby improving the cardiopulmonary environment and mental state.

[0069] Furthermore, this method employs a staged concentration control strategy. When the user's physiological parameters meet the high-hydrogen usage conditions, the main control unit 50 controls the electrolysis current of the electrolytic hydrogen production module 20 to gradually increase, and simultaneously adjusts the opening of the hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60, so that the hydrogen volume concentration in the output gas increases steadily at a fixed rate every preset time interval until the target concentration is reached. During this process, the hydrogen flow sensor 90 and the preset gas flow sensor 100 at the inlet of the mixing pipeline 40 continuously provide real-time flow data, and the main control unit 50 uses this data to make closed-loop corrections to the regulating valve openings, ensuring that the mixed gas composition remains stable within the safe operating range.

[0070] Through the above technical solution, this method effectively solves the defect of traditional equipment that cannot dynamically adjust the gas ratio according to individual differences. Especially in the high hydrogen usage mode, it not only breaks through the safety limit of hydrogen volume concentration not exceeding 4%, but also monitors risk parameters such as ambient hydrogen concentration, mask wearing status and static electricity accumulation in real time through the multi-dimensional safety monitoring module 120. Once an abnormality is detected, it will forcibly switch to the safety mode, retaining only the preset gas or negative oxygen ion output and venting the residual hydrogen. Thus, while expanding the scope of application, it significantly improves the safety, reliability and clinical application value of the equipment.

[0071] Optionally, in the pure hydrogen mode, the adjustable range of hydrogen flow rate is 100-2000 ml / min; in the pure oxygen mode, the preset adjustable range of gas flow rate is 1-10 L / min; in the pure negative oxygen ion mode, the negative oxygen ion flow rate is ≥1 million / cm³, and the preset gas flow rate is 1-5 L / min; in the hydrogen-oxygen mixture or all gas mixture mode, the total flow rate is set to be adjustable from 1-8 L / min, and the hydrogen-oxygen ratio is fixed at 1:24 in the normal mode (hydrogen concentration ≤4%), and can be steplessly adjusted between 2:1 and 1:24 in the high hydrogen usage mode.

[0072] Please see Figure 1 , Figure 5 and Figure 6 This application further proposes a regulation and control method for a multifunctional gas mixing intelligent regulation integrated machine, wherein S20: the steps of adjusting the electrolysis current of the electrolysis hydrogen production module 20 in real time to control the hydrogen flow rate, adjusting the compressor power or speed of the gas production module 10 to control the preset gas flow rate, and adjusting the preset gas flow rate introduced into the negative oxygen ion generating module 30 to control the negative oxygen ion flow rate according to the user's physiological parameters or doctor's prescription input include: S21: Calculate the hydrogen demand flow rate, preset gas demand flow rate, and negative oxygen ion demand flow rate based on the target total flow rate set by the user and the target hydrogen concentration determined by the user's physiological parameters or doctor's prescription input.

[0073] Specifically, the main control unit 50 first obtains the target total flow Q set by the user through the human-computer interaction interface. total —This target total flow rate represents the total rate at which the user expects to inhale the mixed gas, typically ranging from 1 to 8 L / min, and can be customized for different usage scenarios (such as daily health care, exercise recovery, clinical assistance, etc.). Simultaneously, the main control unit 50 determines the target hydrogen volume concentration C based on user physiological parameters (such as blood oxygen saturation, heart rate, etc.) collected from external physiological monitoring equipment or input from a doctor's prescription. H2 The target hydrogen volume concentration reflects the personalized requirements for the proportion of hydrogen in the gas mixture under the current usage scenario; for example, in a regular healthcare mode, this concentration is usually no more than 4%; while in a high-hydrogen usage mode under the guidance of a doctor's prescription, this concentration can exceed the 4% limit as needed. After obtaining the above two parameters, the main control unit 50 uses formula Q... H =Q total ×C H2 Calculate the hydrogen demand flow rate. The calculation of the preset gas demand flow rate needs to be differentiated based on the specific composition of the preset gas: when the preset gas is pure oxygen or a single pure gas, the preset gas demand flow rate Q is... P = Q total ×(1 C H2 When the preset gas is a multi-component mixture (e.g., oxygen-enriched air produced by molecular sieves, with an oxygen volume fraction C...), O2 When the concentration is approximately 90%–95%, with the remainder being nitrogen, etc., if the user is ultimately concerned with the final concentration of a specific component (such as oxygen) in the mixed output gas, it is necessary to convert it based on the preset volume fraction of that component in the gas, i.e., Q. P =Q total ×(C O2 target / C O2 ), where C O2 target is the user's desired oxygen concentration, C. O2 The actual volume fraction of the component in the preset gas is used. The required flow rate of negative oxygen ions is determined based on the user-set target negative oxygen ion concentration or a preset program, and is achieved by adjusting the preset gas flow rate introduced into the negative oxygen ion generating module 30. After the above calculations are completed, the main control unit 50 uses the required flow rate of hydrogen, the preset gas required flow rate, and the required flow rate of negative oxygen ions as input parameters for subsequent synchronous control.

[0074] S22: Based on the hydrogen demand flow rate, the preset gas demand flow rate, and the negative oxygen ion demand flow rate, control signals are simultaneously sent to the hydrogen proportional regulating valve 70, the preset gas proportional regulating valve 60, the electrolytic hydrogen production module 20, the gas production module 10, and the negative oxygen ion generating module 30.

[0075] Specifically, the main control unit 50, based on the hydrogen demand flow rate, preset gas demand flow rate, and negative oxygen ion demand flow rate calculated by S21, simultaneously sends control signals to the five actuators. This synchronous transmission of control signals forms the basis of a dual-layer collaborative control mechanism of "rapid response of the end proportional valve" and "long-term pressure stabilization of the source gas generation module." The hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60, as end actuators, have a fast response speed (typically in the millisecond range) and can quickly act upon receiving the control signal, utilizing the pressure reserve in the gas storage tank or hydrogen storage tank to instantly achieve the required output mixed gas ratio. The electrolytic hydrogen production module 20, the gas production module 10, and the negative oxygen ion generation module 30, as source gas generation mechanisms, have a relatively slow response speed (typically requiring several seconds to tens of seconds to complete the gas production adjustment). However, by synchronously receiving control signals, they can initiate the gas production adjustment process in advance, matching the source gas production with the end demand. This avoids problems such as continuous pressure drop at the source, insufficient gas supply, or long-term system imbalance that may result from relying solely on valve regulation.

[0076] S23: The hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60 are activated to the corresponding opening degree according to the control signal. The electrolytic hydrogen production module 20 adjusts the electrolysis current according to the control signal to match the hydrogen demand flow rate. The gas production module 10 adjusts the compressor power or speed according to the control signal to match the preset gas demand flow rate. S24: The negative oxygen ion generating module 30 adjusts the preset gas flow rate into the negative oxygen ion generating module according to the control signal.

[0077] Specifically, the hydrogen proportional control valve 70 and the preset gas proportional control valve 60 are driven to an opening degree adapted to the target flow rate by their respective actuators (such as stepper motors or proportional electromagnets) according to the control signal. The opening degree of these two proportional control valves is determined collaboratively based on the target mixed gas ratio. For example, if the target hydrogen volume concentration is 4% and the target total flow rate is 3L / min, then the required hydrogen flow rate is 120 ml / min, and the required preset gas flow rate is 2880 ml / min (when the preset gas is pure oxygen). The two proportional control valves are adjusted to their corresponding opening degrees so that the two gases can form the target ratio when they converge in the mixing pipeline 40. At the same time, the electrolytic hydrogen production module 20 changes the hydrogen production rate by adjusting the output current of its electrolysis power supply according to the control signal—when the electrolysis current increases, the electrolysis reaction intensifies and the hydrogen production increases; when the electrolysis current decreases, the hydrogen production decreases accordingly. The gas production module 10 adjusts its internal compressor speed (e.g., via frequency converter control) or duty cycle according to a control signal to change the gas production rate. When the compressor speed increases, the airflow and pressure entering the molecular sieve tower increase, thus increasing the oxygen production rate; conversely, it decreases. The negative oxygen ion generating module 30 controls its negative oxygen ion generation efficiency by adjusting the preset gas flow rate entering the module according to a control signal. A higher preset gas flow rate results in a stronger jet impact from the high-pressure orifice nozzle 32, leading to a higher negative oxygen ion flow rate; conversely, it decreases. Since the negative oxygen ion generating module 30 is connected in series with the preset gas output branch 10a, the preset gas flow rate entering this module is part of the total preset gas flow rate. Therefore, adjusting the negative oxygen ion flow rate must be coordinated with the opening control of the preset gas proportional control valve 60 to ensure that the total preset gas flow rate meets the user-set target total flow rate requirement. Through the coordinated actions of the source and end, the source gas production ratio and the terminal mixing ratio achieve dynamic matching.

[0078] Please see Figure 1 , Figure 5 and Figure 6 The main control unit executes step S20 using a cascaded PID control strategy, which includes: The first PID loop is used to obtain the deviation between the target preset gas flow rate and the actual preset gas flow rate, and adjust the opening of the preset gas proportional control valve 60 according to the deviation to stabilize the preset gas flow rate. Specifically, the first PID loop uses the preset gas flow rate as the controlled variable. The preset gas is both the source of oxygen in the mixed gas and the carrier gas of the negative oxygen ion generating module 30, so the stability of its flow rate directly determines the output quality of the entire system. The input of the first PID loop is the deviation between the target preset gas flow rate (calculated by step S21 based on the target total flow rate and target hydrogen volume concentration set by the user) and the actual preset gas flow rate (feedback in real time by the preset gas flow sensor 100 installed on the output pipeline of the gas generating module 10). After proportional-integral-derivative calculation, the output control quantity adjusts the opening of the preset gas proportional control valve 60 to make the actual preset gas flow rate approach the target value, thereby continuously stabilizing the preset gas flow rate during system operation and providing a stable base flow for the precise control of the second and third PID loops.

[0079] The second PID loop is used to obtain the deviation between the target hydrogen concentration and the actual hydrogen concentration, and adjust the electrolysis current of the electrolysis hydrogen production module 20 according to the deviation. In the mixed gas, the hydrogen concentration is one of the core parameters affecting the performance, but the concentration itself cannot be directly controlled and needs to be indirectly controlled by adjusting the hydrogen flow rate. The input of the second PID loop is the deviation between the target hydrogen concentration (determined by the user's physiological parameters or doctor's prescription) and the actual hydrogen concentration (provided in real time by the hydrogen concentration sensor located downstream of the mixing pipeline 40, or calculated by combining the detection value of the hydrogen flow sensor 90 with the total flow rate). After the deviation value is calculated by the PID, the output control quantity adjusts the electrolysis current of the electrolysis hydrogen production module 20. When the actual concentration is lower than the target concentration, the electrolysis current is increased to increase the hydrogen production and make the concentration rise; when the actual concentration is higher than the target concentration, the electrolysis current is decreased to reduce the hydrogen production and make the concentration fall. The adjustment of the second PID loop must be based on the preset gas flow rate stabilized by the first PID loop, because changes in hydrogen concentration will have a reverse effect on the relative proportion of oxygen in the mixed gas. If the preset gas flow rate is unstable, the control of hydrogen concentration will lose its benchmark.

[0080] Please see Figure 1 and Figure 5 This application further proposes specific steps based on the user's physiological parameters or doctor's prescription input: determining the current working mode to be entered, the working mode including a normal mode and a high-hydrogen usage mode; when the user's physiological parameters meet preset conditions or a doctor's prescription input is received, determining that the current working mode to be entered is the high-hydrogen usage mode; otherwise, determining that the current working mode to be entered is the normal mode.

[0081] Specifically, the main control unit 50 intelligently determines the most suitable operating mode for the device based on user physiological parameters (such as blood oxygen saturation, heart rate, and respiratory rate) obtained from external physiological monitoring devices or prescription information entered by doctors through the device interface. This determination mechanism enables the device to upgrade from a single, passive parameter adjustment to an active mode selection based on actual user needs and medical guidance.

[0082] The aforementioned operating modes are designed to provide the device with two or more preset operating strategies to adapt to different usage objectives. The "Normal Mode" is typically suitable for daily health maintenance, auxiliary use, mild symptom relief, or consumer use. Its gas output parameters (such as hydrogen concentration, preset gas flow rate, and negative ion flow rate) may be set to a relatively mild level or adjustable according to user preferences. Specifically, it limits the hydrogen volume concentration in the output gas to no more than 4% (i.e., a hydrogen-to-oxygen volume ratio of 1:24).

[0083] The "high-hydrogen usage mode" is designed for specific diseases or clinical interventions requiring higher hydrogen concentrations. Its hydrogen output concentration is significantly higher than the conventional mode, specifically allowing a hydrogen volume concentration exceeding 4%, up to a maximum of 66% (i.e., a hydrogen-to-oxygen volume ratio of 2:1), and may be accompanied by more stringent safety monitoring and control strategies. The main control unit 50 can internally preset a set of decision-making logic, such as a rule-based expert system or machine learning model, to analyze input user physiological parameters or doctor's prescriptions and map them to the corresponding operating mode.

[0084] When a user's physiological parameters meet preset conditions, such as blood oxygen saturation falling below a certain threshold and abnormal heart rate persisting for more than a preset duration, or when the main control unit 50 receives a prescription from a doctor explicitly instructing the user to use high-hydrogen mode, the system will automatically determine and switch to high-hydrogen mode. This automatic switching mechanism ensures that the device can provide timely and accurate, more targeted intervention when the user's health condition becomes abnormal or when intensive use is required. Conversely, if the user's physiological parameters are within the normal range and no doctor's prescription for high-hydrogen use has been received, the system will determine and maintain operation in the normal mode.

[0085] Through the aforementioned technical solution, this application can intelligently select the most suitable usage plan based on the user's actual physiological state or professional medical guidance. This avoids the limitations of single fixed parameters or frequent manual adjustments, enabling the device to accurately respond to different usage needs. For example, when the user's physiological parameters become abnormal, the system can automatically switch to a high-hydrogen usage mode, providing more effective intervention (such as increasing the hydrogen concentration to 66%), thereby responding promptly to emergencies and improving the effectiveness and safety of use. In daily use or non-emergency situations, the system maintains the regular mode to avoid unnecessary resource consumption and potential risks. This intelligent mode management significantly improves the device's adaptability, usage accuracy, and user experience.

[0086] The preset conditions include: the blood oxygen saturation of the external physiological monitoring device is lower than the preset threshold and the abnormal heart rate lasts for more than the first preset duration.

[0087] Specifically, external physiological monitoring devices typically refer to pulse oximeters, which non-invasively measure a user's blood oxygen saturation using finger clip or wrist sensors. Blood oxygen saturation is the percentage of oxyhemoglobin in the blood relative to total hemoglobin, and is an important physiological indicator reflecting respiratory and circulatory function. The preset threshold is a lower limit for blood oxygen saturation pre-set by the system, such as 90% or 92% based on clinical guidelines or doctor's recommendations. When the monitored blood oxygen saturation remains below this threshold, the main control unit 50 will identify that the user may be in a state of hypoxia. Simultaneously, the external physiological monitoring device (e.g., an electrocardiogram monitor or a smart wearable device) will also collect the user's heart rate data in real time. Abnormal heart rate refers to a heart rate exceeding the normal range (too fast or too slow), or an irregular heartbeat. The first preset duration is a time length set by the system to determine whether the abnormal heart rate is a persistent state, rather than a brief fluctuation. For example, this duration can be set to 30 seconds or 1 minute based on clinical experience to filter out brief heart rate fluctuations and ensure the persistence of the abnormality. The main control unit 50 continuously monitors heart rate data. Once an abnormal heart rate is detected and continues to reach or exceed the first preset duration, it is considered that the condition is met.

[0088] By employing the aforementioned technical solution, this application establishes a prerequisite for entering high-hydrogen usage mode: the user's blood oxygen saturation level falls below a preset threshold, and abnormal heart rate persists for more than a first preset duration. This enables accurate and real-time assessment of the user's physiological state. When a user experiences a drop in blood oxygen saturation (indicating a risk of hypoxia) accompanied by abnormal heart rate (potentially indicating cardiovascular compensation or dysfunction) for a sustained period, this is typically a clear signal of worsening condition or an emergency. This combined judgment mechanism avoids the possibility of misjudgment based on a single indicator; for example, brief fluctuations in blood oxygen or heart rate may not be a genuine emergency. By introducing the condition of "persisting for more than a first preset duration," the accuracy and reliability of the judgment are further enhanced, effectively filtering out transient physiological fluctuations and ensuring that high-hydrogen usage mode is triggered only in genuine emergency or persistent abnormal states. This allows the integrated device to provide users with high-concentration hydrogen in a timely and automatic manner, providing effective intervention at critical moments, avoiding delays or errors in manual judgment, and significantly improving the timeliness and safety of use.

[0089] Please see Figure 1 and Figure 5 This application further proposes that, in the normal mode, according to the user-input instructions or preset programs, the multi-gas switching module 110 is controlled to selectively output at least one of the following modes: pure hydrogen mode, pure preset gas mode, pure negative oxygen ion mode, hydrogen and preset gas mixing mode, or all gas mixing mode; wherein, when the hydrogen and preset gas mixing mode or all gas mixing mode is selected, the hydrogen volume concentration in the output gas is limited to not exceeding a first preset concentration.

[0090] Specifically, the standard mode is a daily operating state of the multi-functional gas mixing intelligent regulating integrated machine, distinct from the high-hydrogen usage mode. It primarily caters to users' daily health maintenance, wellness needs, or non-emergency usage requirements. In this mode, users can interact with the device in various ways, such as through the touchscreen, physical buttons, knobs, voice recognition module, or a connected smart terminal application, inputting desired commands to select a specific gas output mode. Furthermore, the device can preset various programs that can be automatically executed based on user habits, health management plans, or scheduled tasks. For example, it can automatically switch to a low-concentration hydrogen-oxygen mixture output in sleep mode during specific time periods.

[0091] The multi-gas path switching module 110, as described in the above embodiment, is typically installed inside the housing and electrically connected to the main control unit 50. This multi-gas path switching module 110 typically has three input ports and one output port. The first input port is connected to the output of the electrolytic hydrogen production module 20, the second input port is connected to the output of the gas production module 10, and the third input port is connected to the output of the negative oxygen ion generating module 30. The output port is used to connect to the end regulating valve 80 or a breathing mask. The main control unit 50 achieves precise control of different gas flow paths by controlling the opening and closing of valves or channels inside the multi-gas path switching module 110. For example, when the user selects the pure hydrogen mode, the main control unit 50 will instruct the multi-gas path switching module 110 to only open the passage from the first input port to the output port, while simultaneously closing the passages for the preset gas and the negative oxygen ion gas, thereby achieving the output of pure hydrogen. Similarly, the switching between the pure preset gas mode, the pure negative oxygen ion mode, the hydrogen and preset gas mixing mode, and the mixing mode of all gases is achieved by the main control unit 50 controlling the multi-gas path switching module 110 accordingly.

[0092] When the user selects either the hydrogen-to-preset gas mixing mode or the all-gas mixing mode, to ensure safety, this application specifically emphasizes limiting the hydrogen volume concentration in the output gas to no more than a first preset concentration. This first preset concentration is a pre-set safety threshold, such as 2% or 3% (far below the lower explosive limit of hydrogen in air, 4%). This preset concentration value is typically determined based on safety standards, clinical studies, or industry specifications and is stored in the memory of the main control unit 50. When executing the hydrogen-to-preset gas mixing mode or the all-gas mixing mode, the main control unit 50 monitors and dynamically adjusts the electrolysis current of the hydrogen electrolysis module 20, the compressor power or speed of the gas production module 10, and the opening degrees of the hydrogen proportioning valve 70 and the preset gas proportioning valve 60 in real time to ensure that the hydrogen volume concentration in the mixed gas is always maintained below the first preset concentration. For example, the main control unit 50 can calculate the hydrogen demand flow rate and the preset gas demand flow rate based on the target total flow rate set by the user and the target hydrogen volume concentration determined by the user's physiological parameters or doctor's prescription input, and precisely adjust the working parameters of each module and the opening degree of the proportional control valve through the closed-loop control system.

[0093] Through the above technical solution, this application can greatly enhance the flexibility and personalization of the multi-functional gas mixing intelligent regulating all-in-one machine in conventional mode. Users can conveniently select from various modes such as pure hydrogen, pure preset gas, pure negative oxygen ions, hydrogen mixed with preset gas, or all gas mixture, according to their own needs or health plans, thereby meeting diverse usage requirements. Simultaneously, by strictly limiting the hydrogen volume concentration in the output gas to no more than a first preset concentration in the hydrogen mixed with preset gas or all gas mixture modes, potential safety hazards caused by excessive hydrogen concentration are effectively avoided, ensuring user safety. This design allows the device to provide rich functionality while also ensuring ease of operation and safety, significantly improving user experience and product reliability.

[0094] When switching between different output modes (e.g., from pure hydrogen mode to a hydrogen-preset gas mixture mode), the main control unit 50 uses a ramp-gradual adjustment method to gradually adjust the opening of the hydrogen proportional control valve 70 and the preset gas proportional control valve 60 at a rate of 5% of full scale per second. During the adjustment process, the output gas is forcibly switched to pure oxygen mode as a transition buffer. After the proportional valve opening is adjusted to the appropriate position, the system smoothly switches to the target output mode.

[0095] Furthermore, when switching between different output modes (e.g., from pure hydrogen mode to a hydrogen and preset gas mixture mode, or from pure negative oxygen ion mode to a mixture of all gases), the main control unit 50 employs a two-stage switching strategy combining ramp-up and transition buffering to avoid sudden imbalances in the output mixture composition or instantaneous spikes in hydrogen concentration caused by abrupt changes in the proportions of different gases. The first stage is the transition buffering stage: the main control unit 50 first controls the multi-gas path switching module 110 to forcibly switch the output gas to the pure preset gas mode (i.e., only the preset gas is output, the hydrogen proportioning valve 70 is completely closed, and the negative oxygen ion generating module 30 is suspended), thus serving as a transition buffer for mode switching. The core purpose of this transition buffering stage is to temporarily cut off the hydrogen output during the switching process, fundamentally preventing instantaneous spikes in hydrogen concentration that may occur when the hydrogen proportioning valve 70 and the preset gas proportioning valve 60 are adjusted synchronously due to differences in response speed or timing deviations in control signals, thereby providing a safe gas environment for the subsequent precise adjustment of the proportioning valves. Meanwhile, the preset gas mode ensures the user's basic breathing needs during the switching process, avoiding discomfort caused by gas interruption or imbalance. The duration of the transition buffer phase is dynamically determined by the main control unit 50 based on the degree of difference between the current mode and the target mode, typically ranging from 2 to 5 seconds.

[0096] The second stage is the gradual ramp-in stage: After the transition and buffering stage, the main control unit 50 adopts a gradual ramp-in adjustment method to gradually adjust the opening of the hydrogen proportional control valve 70 and the preset gas proportional control valve 60 to the target opening at a step rate of 5% of full scale per second. Specifically, the main control unit 50 calculates the difference between the current opening and the target opening, divides this difference into multiple small adjustment steps (each step not exceeding 5% of full scale), and sends a control signal once in each step interval, so that the proportional control valve gradually approaches the target position. This gradual adjustment method of "small steps and fast runs" can significantly reduce the airflow impact and pressure fluctuation caused by excessively rapid valve action compared to a one-time large adjustment of the opening. At the same time, it also provides the main control unit 50 with sufficient time window to monitor the feedback signal of the actual flow sensor, ensuring that each adjustment is within the expected control range. During the gradual slope adjustment process, the preset gas proportion regulating valve 60 remains open and continuously outputs preset gas, providing a stable background airflow for the gradual opening of the hydrogen proportion regulating valve 70, thereby further suppressing the instantaneous fluctuation of hydrogen concentration in the initial stage of switching.

[0097] In the above two-stage switching strategy, the multi-gas path switching module 110, the hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60 work together in strict time sequence—first switching the gas path (entering the pure preset gas transition buffer), and then synchronously adjusting the opening of the two proportional valves (gradual ramp entry), thereby ensuring that the gas output to the user is always in a safe and stable state throughout the entire switching process.

[0098] When the user selects the pure hydrogen mode, the main control unit 50, upon receiving the doctor's prescription input and confirming safety, controls the multi-gas switching module 110 to output only hydrogen and activates the safety monitoring strategy.

[0099] Specifically, when a user selects "pure hydrogen mode" through the all-in-one machine's human-machine interface or remote control application, the main control unit 50 recognizes this command. At this time, the main control unit 50 sends a command to the multi-gas path switching module 110, instructing it to only open the path connecting to the output terminal of the electrolysis hydrogen production module 20, while simultaneously closing the paths connecting the gas production module 10 and the negative oxygen ion generating module 30, thus ensuring that only hydrogen is delivered to the user. This precise gas path control is the foundation for achieving a single gas output mode.

[0100] Based on this, the integrated unit will simultaneously activate a pre-set safety monitoring strategy designed to identify and respond to potential hazards. This safety monitoring strategy is a comprehensive safety management framework, including real-time monitoring of various safety parameters, abnormal situation judgment logic, and corresponding emergency response mechanisms. Activating the safety monitoring strategy means that the system will enter a state of high alert, continuously and proactively monitoring key safety indicators related to hydrogen use to prevent accidents.

[0101] Through the above technical solution, when the user selects the pure hydrogen mode, the integrated unit can not only precisely control the multi-gas switching module 110 to output only hydrogen, but more importantly, it can simultaneously activate a comprehensive safety monitoring strategy. This significantly improves the safety of use in pure hydrogen mode, effectively preventing dangers such as fires and explosions that may be caused by hydrogen leakage or accumulation, thereby ensuring the safety of users and equipment.

[0102] Please see Figure 1 and Figure 5 This application further proposes a more comprehensive safety monitoring strategy to ensure safe use in pure hydrogen mode. This safety monitoring strategy includes at least one of the following: continuously monitoring the mask wearing status via an infrared wear detection sensor 122; if the mask is not worn or is loose, immediately shutting off the hydrogen output and triggering an alarm; monitoring the hydrogen concentration around the device in real time via an ambient hydrogen concentration sensor 121 at a frequency not lower than a preset frequency; issuing a warning when the hydrogen concentration exceeds a first proportion, and forcibly shutting off the electrolytic hydrogen production module 20 and starting ventilation when it exceeds a second proportion; monitoring the electrostatic voltage of the output pipeline in real time via an electrostatic detection unit 124; reducing the hydrogen flow rate when the electrostatic voltage exceeds a first preset electrostatic voltage, and immediately cutting off the hydrogen supply and opening the rapid release valve 125 when it exceeds a second preset electrostatic voltage; limiting the duration of continuous use in pure hydrogen mode to a preset value and forcing interval rest; and monitoring the output hydrogen flow rate in real time in pure hydrogen mode, automatically reducing the electrolysis current if the flow rate exceeds a preset safety limit.

[0103] It should be noted that the aforementioned safety monitoring strategy is a proactive and preventative monitoring mechanism, designed for continuous daily monitoring under specific high-risk modes (such as pure hydrogen mode). This safety monitoring strategy employs gradual and reversible intervention measures (such as early warning, flow reduction, and duration limitation) to control risks at their inception. After the anomaly is resolved, the system can automatically recover or require user confirmation before recovery, without affecting the normal operation of the equipment.

[0104] Specifically, the wearing status of the breathing mask is continuously monitored by an infrared wearing detection sensor 122. This sensor is typically integrated into the breathing mask and determines whether the mask fits tightly against the user's face by emitting and receiving infrared signals. If the mask is detected as not being worn or as being loose, it indicates that hydrogen may leak into the environment. At this time, the main control unit 50 will immediately shut off the hydrogen output, stop the operation of the electrolysis hydrogen production module 20, and issue an alarm signal through sound and light to remind the user or caregiver to take timely action, thereby effectively avoiding the risk of hydrogen leakage. The detection period for not wearing or loosening the mask is 3 seconds; that is, if not wearing / loosening is detected for 3 consecutive seconds, an alarm will be triggered and the hydrogen output will be shut off.

[0105] Meanwhile, the ambient hydrogen concentration sensor 121 monitors the hydrogen concentration in the air surrounding the equipment in real time at a frequency no less than a preset frequency. This sensor can be of electrochemical, semiconductor, or catalytic combustion type and is installed on the exterior of the casing or near the equipment. When the detected hydrogen concentration exceeds a first proportion (e.g., 25% of the lower explosive limit of hydrogen), the main control unit 50 will issue a warning signal indicating a potential risk. If the hydrogen concentration further increases and exceeds a second proportion (e.g., 50% of the lower explosive limit of hydrogen), the main control unit 50 will forcibly shut down the electrolytic hydrogen production module 20, stop hydrogen production, and activate the exhaust system to quickly expel the hydrogen around the equipment to eliminate the explosion hazard.

[0106] In addition, the electrostatic detection unit 124 monitors the electrostatic voltage in the output pipeline in real time. Static electricity accumulation may generate sparks in the pipeline, igniting hydrogen gas. The electrostatic detection unit 124 can be a non-contact electrostatic sensor or a contact charge sensor, located at the end of the mixing pipeline 40. When the detected electrostatic voltage exceeds a first preset electrostatic voltage, the main control unit 50 reduces the hydrogen flow rate to reduce friction and electrostatic accumulation. If the electrostatic voltage continues to rise and exceeds a second preset electrostatic voltage, the main control unit 50 will immediately cut off the hydrogen supply and open the quick-release valve 125 to rapidly discharge residual hydrogen gas in the pipeline, thereby effectively preventing fires or explosions caused by electrostatic discharge.

[0107] To ensure user health and stable equipment operation, in pure hydrogen mode, the system limits the continuous use time to a preset value and forces users to take breaks. The main control unit 50 has a built-in timer function. When pure hydrogen mode is activated, the timer starts. Once the preset time (e.g., 60 minutes) is reached, the system will automatically stop hydrogen output and prompt the user to take a break. The system can only be restarted after the break is over, avoiding the uncertain risks that may arise from prolonged inhalation of high-concentration hydrogen.

[0108] Furthermore, in pure hydrogen mode, the system monitors the output hydrogen flow rate in real time. Through a flow sensor installed in the mixing pipeline 40, the main control unit 50 continuously acquires hydrogen flow rate data and compares it with a preset safety limit. If the hydrogen flow rate exceeds the preset safety limit, the main control unit 50 automatically reduces the electrolysis current of the electrolysis hydrogen production module 20, thereby reducing the hydrogen flow rate and bringing it back within the safe range, ensuring the stability and safety of the hydrogen output.

[0109] Through the aforementioned multiple safety monitoring strategies, this application can comprehensively and in real-time monitor various potential risks in pure hydrogen mode. When abnormal mask wearing, excessively high ambient hydrogen concentration, static electricity buildup in pipelines, exceeding usage time limits, or abnormal hydrogen flow are detected, the system can promptly take measures such as shutting off hydrogen output, triggering alarms, activating exhaust ventilation, reducing flow rate, or cutting off and releasing hydrogen, thereby effectively preventing safety accidents such as hydrogen leakage, fire, and explosion. This greatly improves the safety of the multi-functional gas mixing intelligent regulation integrated machine in pure hydrogen mode, ensuring user health and stable equipment operation.

[0110] The safety monitoring strategy automatically stops when the hydrogen volume concentration drops below 4% or when the user exits the high-hydrogen usage mode. When an intervention measure in the safety monitoring strategy (such as shutting off hydrogen output due to a loose mask) is triggered, if the abnormal condition is resolved within a preset time (e.g., 3 seconds), the system automatically resumes hydrogen output and continues monitoring; if the abnormal condition persists for more than the preset time, the system will forcibly switch to safety mode.

[0111] Please see Figure 1 and Figure 5 Furthermore, this application proposes that the operating mode also includes a security mode.

[0112] During the process of mixing the prepared hydrogen with a preset gas or a preset gas stream rich in negative oxygen ions and outputting it to the user, the main control unit 50 monitors at least one of the following safety parameters in real time: ambient hydrogen concentration, mask wearing status, pipeline pressure, static electricity accumulation, electrolysis cell temperature, pure water tank water level, pure water quality, and casing tilt angle. When any safety parameter is detected to exceed the corresponding safety threshold, the main control unit 50 immediately interrupts the current working mode and forcibly switches to the safety mode. In the safety mode, the main control unit 50 shuts off the electrolysis current of the electrolytic hydrogen production module 20 to stop hydrogen production, maintains the compressor power or speed of the gas production module 10, and maintains the preset gas flow rate into the negative oxygen ion generating module 30 to maintain the output of the preset gas or preset gas stream rich in negative oxygen ions, and opens the quick release valve 125 to vent residual hydrogen in the pipeline.

[0113] The safety mode and the aforementioned safety monitoring strategy constitute a layered, collaborative two-tiered safety system, without conflict or overlap. The safety monitoring strategy serves as the first line of defense, responsible for daily proactive monitoring and gradual intervention; while the safety mode is the last line of defense. When the safety monitoring strategy fails to prevent risk escalation or other serious anomalies occur, the system forcibly switches to safety mode. The difference lies in the activation method: the safety monitoring strategy is specifically designed for high-risk modes (such as pure hydrogen mode), employing gradual and reversible measures, and automatically recovering after the anomaly is resolved; the safety mode, on the other hand, applies to serious anomalies occurring in any operating mode, taking thorough and irreversible fallback measures (such as stopping hydrogen production and venting residual hydrogen), and requires manual troubleshooting by the user before recovery. Through the synergistic effect of the two-tiered safety system, flexibility in daily use is ensured while absolute safety is guaranteed in extreme situations.

[0114] Specifically, the safety mode is an emergency response state whose core purpose is to quickly adjust the equipment to the safest operating state when a potential danger is detected, so as to maximize the safety of users and equipment.

[0115] The real-time monitored security parameters include: Ambient hydrogen concentration: The ambient hydrogen concentration in the air surrounding the equipment is detected in real time by an ambient hydrogen concentration sensor 121 installed on the casing. Because hydrogen is flammable and explosive, real-time monitoring is crucial as it could potentially cause a fire or explosion if the ambient hydrogen concentration exceeds a safe threshold.

[0116] Mask wearing status: An infrared wearing detection sensor 122 installed on the breathing mask detects in real time whether the mask is tightly fitted to the user's face. If the mask is not worn properly or is loose, it may cause gas leakage, affecting the effectiveness of use, or even causing hydrogen to accumulate locally, posing a safety hazard.

[0117] Pipeline pressure: The gas pressure within the mixing pipeline 40 is monitored in real time by a pipeline pressure sensor 123 located at the end of the mixing pipeline 40. Abnormal pipeline pressure (too high or too low) may indicate pipeline blockage, leakage, or equipment malfunction, requiring timely handling to avoid pipeline rupture or gas supply interruption. The normal operating pressure range is 20-30 kPa, with a lower alarm limit of 10 kPa (leakage) and an upper alarm limit of 200 kPa (blockage).

[0118] Static electricity buildup: A static electricity detection unit 124, located at the end of the mixing pipeline 40 and spaced apart from the pipeline pressure sensor 123, detects in real time whether static electricity buildup exists in the pipeline. During hydrogen transportation, static electricity buildup may generate sparks and ignite the hydrogen; therefore, monitoring it is a key measure to prevent fires and explosions. When the static voltage exceeds a second preset static voltage, the quick-release valve 125 is opened for a duration of 5 seconds, or closes after a 2-second delay until the static voltage sensor reading returns to zero.

[0119] Electrolyzer temperature: The temperature of the electrolyzer in the hydrogen production module 20 is monitored in real time via a built-in temperature sensor. Excessively high electrolyzer temperature may indicate an abnormal electrolysis process or poor heat dissipation, posing a risk of overheating damage or even safety hazards.

[0120] Pure water tank level: The water level in the pure water storage bottle 31 is monitored in real time by a liquid level sensor. Pure water is an essential medium for the normal operation of the electrolytic hydrogen production and negative oxygen ion generation module 30. If the water level is too low, it will affect gas production and equipment lifespan.

[0121] Pure water quality: The pure water quality in the pure water storage bottle 31 is monitored in real time using methods such as conductivity sensors. Poor water quality may lead to decreased electrolysis efficiency, scaling in the electrolytic cell, or the generation of impurity gases, affecting gas purity and equipment performance.

[0122] Housing tilt angle: The tilt angle of the multi-functional gas mixing intelligent regulating unit is monitored in real time using a tilt sensor. Tilting the equipment may cause internal liquid leakage, component displacement, or operational instability, affecting the safe operation of the equipment.

[0123] When the main control unit 50 detects that any of the above safety parameters exceeds the preset safety threshold, such as excessively high ambient hydrogen concentration, mask detachment, abnormal pipeline pressure, excessive electrostatic voltage, excessively high electrolytic cell temperature, excessively low pure water tank level, substandard pure water quality, or excessive tilt angle of the casing, the system will immediately trigger the safety response mechanism. The main control unit 50 will forcibly interrupt any currently executing operating mode (such as pure hydrogen mode, hydrogen-oxygen mixed mode, etc.) and quickly switch to the aforementioned safety mode.

[0124] In safety mode, the main control unit 50 immediately shuts off the electrolysis current of the electrolysis hydrogen production module 20, thereby stopping hydrogen production and eliminating the potential risks posed by hydrogen at the source. Simultaneously, to ensure users can still receive basic breathing support or comfort in emergencies, the main control unit 50 maintains the compressor power or speed of the gas production module 10 and maintains the preset gas flow rate into the negative oxygen ion generating module 30, continuously outputting the preset gas or a preset gas flow rich in negative oxygen ions. Furthermore, the main control unit 50 opens the quick-release valve 125 to rapidly vent residual hydrogen in the mixing pipeline 40, further reducing the hydrogen concentration in the pipeline and eliminating potential explosion hazards.

[0125] Through the above technical solution, this application can comprehensively cover various safety hazards that may occur during equipment operation. Once any critical safety parameter exceeds the preset threshold, the system will immediately and forcibly switch to a safety mode, rapidly stopping hydrogen production and purging residual hydrogen from the pipeline, thereby effectively eliminating potential risks such as explosions and fires. Simultaneously, by maintaining the output of a preset gas or a preset gas flow rich in negative oxygen ions, it ensures that users can still obtain basic respiratory support or comfort in emergency situations. This proactive and rapid response mechanism significantly improves the safety and reliability of equipment operation, greatly protecting user safety.

[0126] If the triggering condition is a hardware malfunction (such as the electrolyzer temperature exceeding the preset value, the pure water tank level being too low, the pure water quality exceeding the standard, the casing tilt angle exceeding the preset value, internal communication interruption, etc.), the system only allows the user to manually troubleshoot the fault and then restore the normal working mode by operating the reset button or restarting the equipment. If the triggering condition is an externally recoverable condition such as an excessive ambient hydrogen concentration, a mask not being worn or being loose, abnormal pipeline pressure, or static electricity accumulation, the system will automatically issue a prompt sound or interface prompt after the abnormal condition returns to normal and remains stable for a preset time (e.g., the ambient hydrogen concentration drops below 1% and remains stable for 60 seconds, or the mask is correctly worn for more than 3 seconds). After user confirmation, the system will restore the working mode to the state before the malfunction. In safety mode, hydrogen output is completely shut off (hydrogen proportioning valve 70 is closed), but the gas generation module 10 and the negative oxygen ion generating module 30 remain operational to continuously output a preset gas or a preset gas flow rich in negative oxygen ions to ensure basic respiratory support for the user.

[0127] Once the ambient hydrogen concentration exceeds 2%, the electrolysis hydrogen production module 20 is forcibly shut down and cannot automatically resume hydrogen production. The high-hydrogen mode can only be restarted by the user manually clicking "Confirm Resumption" after the ambient concentration drops below 1% and remains stable for 60 seconds.

[0128] When switching from the conventional mode to the high-hydrogen usage mode, the main control unit 50 performs the following operations: The electrolysis current of the electrolysis hydrogen production module 20 is gradually increased, and the opening of the hydrogen proportion regulating valve 70 and the preset gas proportion regulating valve 60 are adjusted simultaneously; so that the hydrogen volume concentration in the output gas increases at a step rate of increasing the third proportion every second preset time period until the target hydrogen concentration is reached; the target hydrogen concentration is determined by the user's physiological parameters or the doctor's prescription input.

[0129] Specifically, the main control unit 50 controls the gradual increase of the electrolysis current of the electrolysis hydrogen production module 20 to achieve a stable and gradual increase in hydrogen flow rate. For example, the main control unit 50 can send a series of gradually increasing voltage or current control signals to the power controller of the electrolysis hydrogen production module 20, so that the electrolysis current increases slowly according to a preset slope or step size, thereby avoiding sudden and large fluctuations in hydrogen flow rate.

[0130] Simultaneously, the main control unit 50 adjusts the opening of the hydrogen proportional regulating valve 70 and the preset gas proportional regulating valve 60. This is to ensure that the hydrogen-oxygen ratio in the mixed gas is precisely controlled as the hydrogen flow rate gradually increases, and that the hydrogen volume concentration rises at a preset step rate. The main control unit 50 can precisely adjust the opening of these two regulating valves by driving a stepper motor or a proportional solenoid valve based on real-time monitoring of the hydrogen and preset gas concentrations, combined with the target concentration rise curve, to maintain the stability and gradual increase of the mixed gas concentration.

[0131] To achieve a smooth increase in hydrogen volume concentration, the main control unit 50 is configured to increase the hydrogen volume concentration in the output gas at a step rate of a third percentage increase every second preset time interval. This means that the main control unit 50 internally sets a time interval (second preset time interval) and a concentration increment (third percentage). After each time interval, the main control unit 50 increases the current target hydrogen concentration by a preset increment and adjusts the electrolysis current and the opening of the proportional control valve accordingly until the final target hydrogen concentration is reached. This step-by-step increase effectively avoids sudden concentration changes and provides a more comfortable adaptation process for the user. In one specific embodiment, the second preset time interval is set to 10 seconds, and the third percentage is set to 1%, meaning the hydrogen volume concentration increases at a step rate of 1% every 10 seconds until the target concentration is reached.

[0132] The target hydrogen flow rate is determined by the user's physiological parameters or the doctor's prescription, reflecting the personalization and precision of the use. The main control unit 50 can have a built-in intelligent algorithm or parameter mapping table to calculate or query the most suitable target hydrogen concentration for the current user based on the user's blood oxygen saturation, heart rate, and other physiological parameters collected by external physiological monitoring equipment, or the specific usage plan entered by the doctor on the operation interface (e.g., requiring a specific percentage of hydrogen concentration).

[0133] Through the above technical solution, when the system switches from the conventional mode to the high-hydrogen usage mode, the hydrogen output concentration can be increased gradually and steadily, rather than suddenly reaching the target concentration. The main control unit 50 controls the electrolysis current of the electrolytic hydrogen production module 20 and synchronously adjusts the opening of the hydrogen proportioning valve 70 and the preset gas proportioning valve 60 to ensure that the hydrogen volume concentration increases at a preset step rate until it reaches the target concentration determined by the user's physiological parameters or a doctor's prescription. This controlled concentration increase process effectively avoids user discomfort or physiological stress reactions that may be caused by a sudden increase in hydrogen concentration, significantly improving user comfort and safety. Simultaneously, determining the target hydrogen flow rate based on individualized physiological parameters or a doctor's prescription achieves precise and personalized use, thereby improving user compliance and effectiveness.

[0134] The following is a specific example to better illustrate the content of this case.

[0135] In a home environment, User A uses a multi-functional gas mixing and intelligent regulating unit for daily use. This multi-functional gas mixing and intelligent regulating unit integrates multiple core functional modules and is intelligently managed by a main control unit 50.

[0136] First, the multi-functional gas mixing intelligent regulating integrated machine houses a gas generating module 10 and an electrolytic hydrogen generating module 20. The gas generating module 10 is responsible for separating and preparing a high-purity preset gas from the air, while the electrolytic hydrogen generating module 20 produces hydrogen by electrolyzing pure water. To provide additional functionality, the integrated machine also includes a negative ion generating module 30. This module introduces the preset gas output from the gas generating module 10 into a pure water storage bottle 31, and then forms a high-speed preset gas jet through a high-pressure orifice nozzle 32, impacting the plate 33 or the surface of the pure water, thereby generating a preset gas flow rich in negative oxygen ions. This design physically isolates the output end of the negative ion generating module 30, which is connected in series on the preset gas output branch 10a, from the output end of the electrolytic hydrogen generating module 20, effectively avoiding the potential mixing risk of hydrogen and the preset gas during the negative ion generation process and improving safety.

[0137] The prepared preset gas, hydrogen, and preset gas stream rich in negative oxygen ions are each connected to a mixing pipeline 40 through their respective output ends. This mixing pipeline 40 is responsible for mixing these three gas streams in a preset ratio and then connecting its output port to a terminal regulating valve 80, ultimately delivering the mixture to user A through a breathing mask. At the inlet of the mixing pipeline 40, a hydrogen flow sensor 90 and a preset gas flow sensor 100 are also installed to detect the hydrogen and preset gas concentrations in the mixed gas in real time.

[0138] The main control unit 50 of the all-in-one machine is the core of the entire system. It is electrically connected to the gas generation module 10, the electrolysis hydrogen generation module 20, the negative oxygen ion generation module 30, and various sensors. The main control unit 50 can also be electrically connected to external physiological monitoring devices (e.g., a pulse oximeter worn on user A's wrist).

[0139] During user A's daily use, external physiological monitoring devices continuously collect user A's physiological parameters, such as blood oxygen saturation and heart rate. When the main control unit 50 receives these physiological parameters and determines that they meet preset conditions (e.g., blood oxygen saturation is below a preset threshold and abnormal heart rate persists for more than a first preset duration), or when it receives a doctor's prescription input, the main control unit 50 will intelligently adjust the working mode and gas output parameters of the all-in-one machine based on this information.

[0140] For example, in normal mode, user A can select different output modes through the all-in-one machine's operating interface, such as pure oxygen mode, pure negative oxygen ion mode, hydrogen-oxygen mixed mode, or all gas mixed mode. When the hydrogen-oxygen mixed mode is selected, the main control unit 50 controls the compressor power or speed of the gas generating module 10, the electrolysis current of the electrolytic hydrogen generating module 20, and the preset gas flow rate into the negative oxygen ion generating module 30 to precisely control the flow rates of hydrogen, preset gas, and negative oxygen ions. Simultaneously, the main control unit 50 also adjusts the opening of the preset gas proportional regulating valve 60 on the preset gas output branch 10a and the hydrogen proportional regulating valve 70 at the output end of the electrolytic hydrogen generating module 20 to achieve the target gas ratio. Through real-time feedback from the hydrogen flow sensor 90 and the preset gas flow sensor 100, the main control unit 50 can perform closed-loop control to ensure accurate and stable output gas concentration. Compared with existing devices that are limited in function and cannot flexibly adjust the types and proportions of gases, this all-in-one machine can provide multiple gas combinations and precise concentration control according to user A's personalized needs, significantly improving the targeting and effectiveness of its use.

[0141] When user A's physiological parameters meet preset conditions, such as persistently low blood oxygen saturation and abnormal heart rate, the main control unit 50 determines that it should enter a high-hydrogen usage mode. At this time, the main control unit 50 gradually increases the electrolysis current of the electrolysis hydrogen production module 20 and simultaneously adjusts the opening of the hydrogen proportion regulating valve 70 and the preset gas proportion regulating valve 60. The hydrogen volume concentration in the output gas will steadily increase at a step rate of increasing by a third proportion every second preset time interval until the target hydrogen flow rate determined by the user's physiological parameters or doctor's prescription is reached. This gradual concentration increase method avoids the discomfort that may be caused by a sudden input of high-concentration hydrogen, improving the safety of use. Existing technologies typically limit the mixed gas ratio to a low level for safety reasons, while this all-in-one machine, through intelligent control and multi-dimensional safety monitoring, can achieve the application of high-concentration hydrogen under safe and controllable conditions, breaking through the limitations of existing technologies.

[0142] To ensure user A's safety during use, the all-in-one machine also integrates a multi-dimensional safety monitoring module 120. This module includes: an environmental hydrogen concentration sensor 121 mounted on the casing for real-time monitoring of the hydrogen concentration in the air surrounding the device; an infrared wearing detection sensor 122 mounted on the breathing mask for detecting whether the mask is tightly fitted to user A's face; a pipeline pressure sensor 123 located at the end of the mixing pipeline 40 for detecting the gas pressure within the pipeline; and an electrostatic detection unit 124 spaced apart from the pipeline pressure sensor 123 for detecting static electricity accumulation.

[0143] When user A selects the pure hydrogen mode, the main control unit 50 initiates a series of safety monitoring strategies. For example, the infrared wear detection sensor 122 continuously monitors the mask wearing status. If it detects that the mask is not worn or is loose, the main control unit 50 immediately shuts off the hydrogen output and issues an alarm. The ambient hydrogen concentration sensor 121 monitors the hydrogen concentration around the device in real time at a frequency no less than a preset frequency. When the concentration exceeds a first proportion, it issues a warning; when it exceeds a second proportion, it forcibly shuts off the electrolysis hydrogen production module 20 and starts the exhaust. The electrostatic detection unit 124 monitors the electrostatic voltage of the output pipeline in real time. When the electrostatic voltage exceeds a first preset electrostatic voltage, it reduces the hydrogen flow rate; when it exceeds a second preset electrostatic voltage, it immediately cuts off the hydrogen supply and opens the rapid release valve 125. In addition, in pure hydrogen mode, the duration of continuous use is limited to a preset value, and mandatory intervals for rest are enforced to further ensure safety. These comprehensive safety monitoring and control measures are not available in existing single-function devices, greatly improving the safety of the equipment in high-concentration hydrogen application scenarios.

[0144] Throughout the gas output process, the main control unit 50 also monitors safety parameters in real time, including ambient hydrogen concentration, mask wearing status, pipeline pressure, static electricity accumulation, electrolytic cell temperature, pure water tank level, pure water quality, and casing tilt angle. If any safety parameter exceeds its corresponding safety threshold, the main control unit 50 immediately interrupts the current operating mode and forcibly switches to a safety mode. In safety mode, the main control unit 50 shuts off the electrolysis current of the hydrogen production module 20 to stop hydrogen production, but maintains the compressor power or speed of the gas production module 10 and the preset gas flow rate into the negative oxygen ion generating module 30 to maintain the output of the preset gas or a preset gas rich in negative oxygen ions. It also opens the quick-release valve 125 at the end of the mixing pipeline 40 to discharge residual hydrogen to the outside or the catalytic hydrogen eliminator. This rapid-response safety mechanism ensures that potential risks can be quickly eliminated under any abnormal circumstances, protecting the life safety of user A.

[0145] In summary, this multifunctional gas mixing and intelligent regulating integrated machine achieves integrated preparation and intelligent output of hydrogen, preset gases, and negative oxygen ions through the organic combination of the casing, gas generation module 10, electrolytic hydrogen generation module 20, negative oxygen ion generation module 30, mixing pipeline 40, and main control unit 50. The main control unit 50 adaptively adjusts the gas type, ratio, and flow rate based on user physiological parameters collected by external physiological monitoring equipment or doctor's prescriptions, and is supplemented by multi-dimensional safety monitoring and control strategies. This solves many problems in existing technologies, such as single function, inability to personalize adjustment, difficulty in safely achieving high-concentration hydrogen use, and lack of negative oxygen ion function, significantly improving the intelligence, flexibility, and safety of the equipment.
