Abstract
Description
Technical Field
[0001] This invention relates to the field of home-use intelligent hydrogen and oxygen therapy technology, and in particular to a home-use therapeutic device that generates hydrogen and oxygen through water electrolysis for human inhalation. Background Technology
[0002] Hydrogen has been proven to have positive physiological effects on the human body, such as anti-oxidation, anti-inflammation, and enhancing cell vitality. Home-use hydrogen-oxygen therapy machines produce hydrogen and oxygen through water electrolysis technology, allowing users to choose between single hydrogen gas or a mixture for inhalation, achieving health maintenance and adjunctive therapy purposes. However, existing home-use hydrogen-oxygen therapy machines have significant shortcomings in terms of safety, reliability, and user experience.
[0003] Low safety: Existing home-use hydrogen oxygen therapy machines generally lack real-time, multi-level monitoring of key operating parameters (such as water flow, differential pressure, water quality, water level, and temperature). They also lack effective early warning and immediate protection mechanisms for common faults such as water leakage, gas leakage, and sensor malfunction, posing safety hazards.
[0004] Poor reliability and stability: Most existing home-use hydrogen-oxygen therapy machines use open-loop control, meaning that the control chip sends commands unidirectionally to drive the electrolyzer. This lacks real-time feedback on the actual working status (such as current and voltage) and output of the electrolyzer, making it impossible to precisely adjust the power. This results in unstable gas production, poor long-term reliability of the equipment, and a shortened lifespan.
[0005] Poor human-computer interaction experience: The human-computer interaction interface of existing home hydrogen-oxygen therapy machines is usually quite rudimentary, only displaying limited information such as working time and temperature. Users cannot obtain detailed working status and historical operating data, and when the device malfunctions, they often only receive simple indicator light alarms, lacking intuitive explanations of the cause of the malfunction and troubleshooting guidance. This leads to poor communication between users and the device, resulting in a poor user experience.
[0006] Therefore, there is an urgent need in this field for a home-use intelligent hydrogen-oxygen therapy machine with comprehensive safety monitoring, intelligent closed-loop control and rich human-computer interaction functions, to fundamentally solve its shortcomings in safety, reliability and user experience. Summary of the Invention
[0007] The present invention aims to overcome the shortcomings of the prior art and provide a highly safe home-use intelligent hydrogen-oxygen therapy machine and its working method. Its core purpose is to fundamentally improve the safety, operational reliability and user satisfaction of the device by constructing a multi-level safety monitoring system, introducing a closed-loop intelligent control system and enhancing human-computer interaction functions.
[0008] To achieve the above objectives, the technical solution of the present invention is as follows:
[0009] A highly safe home-use intelligent hydrogen-oxygen therapy machine and its operating method are disclosed. The home-use intelligent hydrogen-oxygen therapy machine includes a housing, within which are integrated basic functional modules, a control module, a safety monitoring system, and a human-computer interaction system that are coupled together and uniformly coordinated and controlled by a main control unit.
[0010] The basic functional modules include a water tank and an electrolytic cell connected by pipelines, a hydrogen gas-liquid separator and an oxygen gas-liquid separator for separating hydrogen and oxygen respectively, a circulating water pump for supplying water to the electrolytic cell, a filter resin for filtering water quality, a water replenishment pump for replenishing water to the water tank, a water drain pump for emptying or replacing water, an ultraviolet sterilization module installed on the bottom of the outside of the water tank, a fan module for heat dissipation, and a power supply module for supplying power to the electrolytic cell.

[0012] The safety monitoring system includes a water flow sensor and a multi-functional water condition sensor, both connected to the main control unit, for monitoring water circuit safety; a hydrogen differential pressure sensor and an oxygen differential pressure sensor for monitoring gas circuit safety; and an electrolytic cell temperature sensor and an ambient temperature sensor for monitoring thermal safety.
[0013] The human-computer interaction system includes a touch screen on the surface of the housing for status display and parameter setting, a voice interaction module for voice prompts and alarms, and an LED alarm light for providing visual warnings;
[0014] The main control unit is configured to execute an integrated safety and control strategy: based on the target gas flow rate set by the user, and based on the real-time differential pressure signals fed back by the hydrogen differential pressure sensor and the oxygen differential pressure sensor, as well as the electrolyzer operating electrical parameters fed back by the current detection unit and the voltage detection unit, the output power of the power supply module is dynamically adjusted through a closed-loop control algorithm to accurately stabilize the gas production rate of the electrolyzer; at the same time, the data of all sensors in the safety monitoring system are continuously polled, and when any data exceeds a preset safety threshold, the power supply to the electrolyzer is immediately cut off and the alarm of the human-machine interaction system is triggered.
[0015] Preferably, the hydrogen output end of the electrolyzer is connected to the hydrogen gas-liquid separation device through an independent pipeline, and its outlet is connected to the hydrogen differential pressure sensor; the oxygen output end of the electrolyzer is connected to the oxygen gas-liquid separation device through an independent pipeline, and its outlet is connected to the oxygen differential pressure sensor; thus forming a dual gas path system in which hydrogen and oxygen are completely isolated and independently perform gas-liquid separation and safety monitoring.
[0016] Preferably, the main control unit is configured to: calculate the real-time hydrogen and oxygen flow rates using the differential pressure signals detected by the hydrogen differential pressure sensor and the oxygen differential pressure sensor, combined with a pre-stored flow-differential pressure relationship model, for the purpose of closed-loop control; simultaneously, by monitoring the absolute pressure signals on the high-pressure side of the hydrogen differential pressure sensor and the oxygen differential pressure sensor, to achieve independent safety monitoring of pipeline overpressure, and to immediately execute power cut-off and alarm when the pressure value exceeds the safety set upper limit.
[0017] Preferably, the main control unit is configured to execute a hierarchical security strategy:
[0018] When the water flow sensor detects that the water flow rate is lower than the preset safety threshold, or when the water condition multi-function sensor detects that the water temperature, water quality, or water level does not meet the preset conditions, the device is prevented from starting or is immediately stopped during operation.
[0019] When the temperature detected by the electrolytic cell temperature sensor exceeds the first-level temperature threshold, the fan module is controlled to enhance heat dissipation; if the temperature continues to rise and exceeds the higher second-level temperature threshold, the power supply is immediately cut off and an alarm is triggered.
[0020] Preferably, the power supply module is a programmable switching power supply, whose control terminal is connected to the main control unit and receives PWM signals or analog voltage signals from the main control unit to precisely adjust the power output to the electrolytic cell.
[0021] Preferably, the human-computer interaction system is configured such that, when the equipment malfunctions, the voice interaction module broadcasts the cause of the malfunction and troubleshooting steps, the touch screen displays detailed alarm information and instructions simultaneously, and the LED alarm light provides visual warnings, together forming a multimedia alarm system that combines sound, light, graphics and text.
[0022] Meanwhile, the present invention also provides a working method for the above-mentioned high-safety home-use intelligent hydrogen-oxygen therapy machine, characterized by comprising the following steps:
[0023] S1. When the user turns on the device via the touch screen, the main control unit starts the system self-test program, sequentially checking whether the water tank level, water temperature, water quality, internal ambient temperature of the equipment, and the communication status of each sensor are normal.
[0024] S2. If the system self-test is normal, it will enter the standby interface and wait for user commands; if the self-test is abnormal, the device will be locked immediately and the corresponding alarm will be triggered.
[0025] S3. After receiving the start command, the main control unit controls the circulating water pump to start and detects the water flow through the water flow sensor.
[0026] S4. If the water flow is normal, the main control unit calculates the initial power output parameters based on the target flow rate and controls the power module to supply power to the electrolyzer according to these parameters, starting the electrolysis gas production process; if the water flow signal is abnormal, the start-up process is terminated immediately and the alarm of the corresponding item is triggered.
[0027] S5. During operation, the main control unit continuously collects the working current and working voltage of the electrolyzer, and collects differential pressure signals from the hydrogen differential pressure sensor and the oxygen differential pressure sensor respectively.
[0028] S6. The main control unit calculates the real-time flow rates of hydrogen and oxygen based on the differential pressure signals of hydrogen and oxygen and the pre-stored flow-differential pressure relationship model, compares them with the target flow rate set by the user, and dynamically adjusts the power output to achieve closed-loop flow control.
[0029] S7. The safety monitoring system performs continuous cyclical monitoring throughout the entire operation of the equipment;
[0030] S8. When any sensor value exceeds the limit, the main control unit immediately cuts off the power supply to the electrolytic cell and triggers an alarm in the human-machine interaction system.
[0031] S9. During normal operation, the touch screen updates the operating parameters in real time. All data is uploaded to the cloud server through the communication unit and can be synchronized to the user's smart mobile terminal as needed.
[0032] Compared with the prior art, the beneficial effects of the present invention are:
[0033] 1. Comprehensive safety protection: By integrating multiple sensors such as water flow, differential pressure, water quality, water level, and temperature, a three-dimensional safety monitoring network is constructed, which enables early detection and immediate intervention of potential risks. It can automatically cut off the source of danger (electrolytic cell power supply) and clearly inform users of the specific situation through various means such as sound, light, and graphics, fundamentally eliminating safety hazards in the home environment.
[0034] 2. High reliability and long lifespan: A closed-loop control system based on real-time feedback of current, voltage and gas differential pressure signals (used for real-time calculation of gas flow) is introduced, which enables the main control unit to accurately sense and control the working status and output efficiency of the electrolyzer. This not only ensures the high stability of gas production flow and meets the needs of precision treatment, but also avoids the electrolyzer from working in an overloaded or inefficient state for a long time due to power imbalance, which significantly improves the overall reliability of the equipment and the service life of core components.
[0035] 3. Intelligent and Superior User Experience: A large touchscreen display and intelligent voice interaction module provide an intuitive, rich, and user-friendly two-way human-machine interface. The device not only comprehensively displays real-time and historical data but also proactively "speaks" during malfunctions, accurately guiding users in troubleshooting and resolution. This significantly reduces the user's learning curve and anxiety. Combined with data storage and remote communication functions, it achieves transparent management and personalized services, greatly enhancing user trust, reliance, and satisfaction.

Obviously, what is described herein are only some embodiments of the invention, not all embodiments, and are not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.
[0045] Example 1;
[0046] Please see Figures 1 to 5 A highly safe home-use intelligent hydrogen-oxygen therapy machine, its core lies in the four interconnected systems integrated within the casing 1 and uniformly coordinated and controlled by the main control unit 31: a basic function module, a control module 30, a safety monitoring system, and a human-computer interaction system, wherein:
[0047] Basic functional modules include: water tank 2, electrolytic cell 3, hydrogen gas-liquid separation device 4a and oxygen gas-liquid separation device 4b for separating hydrogen and oxygen respectively, circulating water pump 5 for supplying water to electrolytic cell 3 and water quality filtration device filter resin 8, water replenishment pump 6 for supplying water to water tank 2, drainage pump 7 for emptying or changing water, ultraviolet sterilization module 9 installed on the bottom of the outside of water tank 2, fan module 10 for heat dissipation, power supply module 11 for supplying power to electrolytic cell 3, and hydrogen and oxygen gas outlet 21 fixed on the upper end of the front shell and water inlet and outlet 22 fixed on the lower end of the rear shell.
[0048] The control module 30, as the control center of the equipment, includes a main control unit 31, a current detection unit 32 connected to the main control unit 31 for real-time detection of the working current of the electrolytic cell 3, a voltage detection unit 33 for real-time detection of the working voltage, a storage unit 34 for storing historical data of equipment operation, alarm records, user setting parameters and user experience reports, and a communication unit 35 for uploading equipment data to a cloud server or interacting with the user's smart mobile terminal (such as a mobile APP).
[0049] Safety monitoring system: Composed of multiple sensors, all connected to the main control unit 31, forming a comprehensive safety protection network, including:
[0050] Waterway safety: A water flow sensor 12 is connected to a hose 20 leading to the water inlet of the electrolysis cell 3 to detect whether the waterway is unobstructed and prevent leakage or slow water flow; and a multi-function water condition sensor 50, whose probe is set in the water tank 2, integrates a temperature probe 54 for detecting water temperature, a TDS probe 55 for detecting water quality, a water level float 52 for indicating water level, a high water level ball 51 for water level warning, and a low water level ball 53;
[0051] Gas circuit safety: Two independent differential pressure sensors are provided, namely hydrogen differential pressure sensor 13a and oxygen differential pressure sensor 13b; among them, hydrogen differential pressure sensor 13a is connected to the outlet pipeline of hydrogen gas-liquid separator 4a and is specifically used to monitor the pressure and differential pressure of hydrogen pipeline; oxygen differential pressure sensor 13b is connected to the outlet pipeline of oxygen gas-liquid separator 4b and is specifically used to monitor the pressure and differential pressure of oxygen pipeline.
[0052] Thermal safety: Ambient temperature sensor 14, fixed to the inner wall of the housing, is used to monitor the internal ambient temperature of the equipment and electrolytic cell temperature sensor 15, which is directly fixed to the electrolytic cell 3 and used to accurately monitor the working temperature of the electrolytic cell 3.
[0053] The human-machine interaction system includes a touch screen 40, which is set on the surface of the housing and is used to display the equipment status, real-time operating parameters (including but not limited to hydrogen and oxygen gas flow rate, concentration, temperature, pressure, timer setting, cumulative working time, etc.), alarm information and historical data, and to receive user commands (such as power on / off, timer, water replenishment / drainage, ultraviolet sterilization switch, etc.); as well as a voice interaction module 41 and an LED alarm light 42. They work together with the touch screen 40 to form a multimedia alarm system combining sound, light, and graphics when the equipment malfunctions. The voice interaction module 41 can broadcast the cause of the malfunction and troubleshooting steps in detail, while the LED alarm light 42 provides a conspicuous visual warning.
[0054] Furthermore, the main control unit 31 executes an integrated control and safety strategy: at the control level, based on the target gas flow rate set by the user, it integrates the differential pressure signals fed back by the hydrogen differential pressure sensor 13a and the oxygen differential pressure sensor 13b (calculated as real-time flow rate by the model), the electrical parameters fed back by the current detection unit 32 and the voltage detection unit 33, and dynamically adjusts the output power of the power module 11 (e.g., through PWM signal or analog voltage signal) through a built-in closed-loop control algorithm (e.g., PID), thereby achieving precise and stable control of the gas production rate of the electrolyzer 3; at the safety level, the main control unit 31 continuously polls the data of all sensors in the safety monitoring system, and immediately triggers the protection program once any data exceeds the preset safety threshold.
[0055] Furthermore, this invention constructs a completely isolated dual-gas-path system. The hydrogen output end of the electrolyzer 3 is connected to the hydrogen gas-liquid separator 4a through an independent pipeline, and its outlet is connected to the hydrogen differential pressure sensor 13a. The oxygen output end of the electrolyzer 3 is connected to the oxygen gas-liquid separator 4b through an independent pipeline, and its outlet is connected to the oxygen differential pressure sensor 13b. This design ensures that hydrogen and oxygen are physically isolated from generation to output, realizing independent gas-liquid separation and monitoring.
[0056] Furthermore, both the hydrogen differential pressure sensor 13a and the oxygen differential pressure sensor 13b are configured to perform dual monitoring functions, forming a dual loop that separates control and safety: First, the differential pressure signal obtained through their differential pressure measurement ports, combined with a pre-stored flow-differential pressure relationship model, calculates the real-time flow rates of hydrogen and oxygen respectively, providing accurate feedback for closed-loop control; Second, the absolute pressure signal obtained through their high-pressure side pressure ports independently monitors the static pressure of their respective pipelines in real time. This signal is directly used for overpressure judgment, and once overpressure occurs, the highest priority power-off protection is immediately triggered.
[0057] Furthermore, the main control unit 31 is configured to execute a tiered security strategy to address risks in a differentiated manner:
[0058] Level 1 Risk (Active Intervention): When the temperature detected by the electrolytic cell temperature sensor 15 exceeds the first-level threshold, the main control unit 31 controls the fan module 10 to enhance heat dissipation;
[0059] Level 2 Risk (Protective Shutdown): When water flow interruption, abnormal water level, water quality exceeding standards, electrolytic cell temperature exceeding the second-level safety limit, or pipeline overpressure is detected (judged by the absolute pressure signal on the high-pressure side of the hydrogen / oxygen differential pressure sensor), the main control unit 31 immediately executes protective actions: immediately cuts off the power supply module 11 to the electrolytic cell 3, and simultaneously triggers the human-machine interaction system to execute a multimedia alarm. This alarm is completed by the voice interaction module 41 broadcasting, the touch screen display 40 displaying, and the LED alarm light 42 flashing, forming a three-dimensional alarm system combining sound, light, and graphics.
[0060] Furthermore, the power supply module 11 is a programmable switching power supply, and its control terminal is connected to the main control unit 31. The main control unit 31 sends a PWM signal or an analog voltage signal to the power supply module 11 according to the control algorithm, thereby precisely and linearly adjusting the power output to the electrolytic cell 3.
[0061] Example 2;
[0062] Please see Figure 6 The present invention provides a method for operating a highly safe home-use intelligent hydrogen-oxygen therapy machine. For ease of explanation, only the parts related to the embodiments of the present invention are shown, and are described in detail below:
[0063] S1. The user turns on the device via the touch screen 40. The main control unit 31 starts the system self-test program and sequentially checks the water level, water temperature, water quality, internal ambient temperature of the equipment, and the communication status of each sensor to see if they are normal.
[0064] S2. If the system self-test is normal, it will enter the standby interface and wait for user commands; if the self-test is abnormal, the device will be locked immediately and the corresponding alarm will be triggered.
[0065] S3. After receiving the start command, the main control unit 31 controls the circulating water pump 5 to start and detects the water flow through the water flow sensor 12.
[0066] S4. If the water flow is normal, the main control unit 31 calculates the initial power output parameters according to the target flow rate and controls the power module 11 to supply power to the electrolytic cell 3 according to these parameters to start the electrolysis gas production process; if the water flow signal is abnormal, the start-up process is terminated immediately and the alarm of the corresponding item is triggered.
[0067] S5. During operation, the main control unit 31 continuously collects the working current and working voltage of the electrolytic cell 3, and collects the differential pressure signals from the hydrogen differential pressure sensor and the oxygen differential pressure sensor respectively.
[0068] S6 and main control unit 31 calculate the real-time flow rates of hydrogen and oxygen based on the differential pressure signal of hydrogen and oxygen and the pre-stored flow-differential pressure relationship model, respectively, compare them with the target flow rate set by the user, and dynamically adjust the power output to achieve closed-loop flow control.
[0069] S7. The safety monitoring system performs continuous cyclical monitoring throughout the entire operation of the equipment;
[0070] S8. When any sensor value exceeds the limit, the main control unit 31 immediately cuts off the power supply to the electrolytic cell 3 and triggers an alarm in the human-machine interaction system.
[0071] S9. During normal operation, the touch screen 40 updates the operating parameters in real time, and all data is uploaded to the cloud server through the communication unit 35, and can be synchronized to the user's smart mobile terminal as needed.
[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
