[0015] In order to more clearly illustrate the technical solutions in the present invention or the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. The drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0016] Figure 1 This is one of the structural diagrams of the photoelectric synergistic pure oxygen source negative ion generation system provided in an embodiment of the present invention; Figure 2 This is the second structural diagram of the photoelectric synergistic pure oxygen source negative ion generation system provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0018] The working principle of traditional negative oxygen ion generators is usually to discharge ambient air containing multiple pollutants to generate negative ions. Due to the complexity and instability of air composition, traditional technology makes it difficult to achieve source control of the purity of negative oxygen ions. As a result, the so-called "negative oxygen ions" generated are actually mixed with various charged components, posing a potential threat to human health.

[0019] Therefore, research on the purity of negative oxygen ions at the source has revealed that while water electrolysis technology has been maturely applied in hydrogen production, its byproduct, high-purity oxygen (purity >99.5%), has long been underutilized, resulting in significant resource waste. This demonstrates the technical limitations of both aforementioned fields. Using high-purity oxygen produced by water electrolysis as the source medium for negative oxygen ion generation would effectively address the key issues in both fields. On the one hand, it would effectively prevent the contamination of ambient air pollutants, ensuring the purity of negative oxygen ions at the source; on the other hand, it would provide high-value-added applications for the oxygen byproduct of water electrolysis, achieving resource recycling.

[0020] Therefore, in response to this technological gap, the present invention has improved a negative ion generation system based on a photoelectric synergistic pure oxygen source. The negative ion generation system can use electrolysis of high-purity oxygen as the reaction medium, ensure the purity of negative oxygen ions from the source, and significantly improve the efficiency and stability of negative oxygen ion generation, and increase the concentration of negative oxygen ions, thereby posing a potential threat to human health.

[0021] Specifically, Figure 1 This is one of the structural schematic diagrams of the photoelectric synergistic pure oxygen source negative ion generation system provided in an embodiment of the present invention.

[0022] like Figure 1 As shown, the photoelectric synergistic pure oxygen source negative ion generation system provided in an embodiment of the present invention may include a photovoltaic power generation device 1, an AC / DC inverter device, an electrolyzer 5, an oxygen flow monitor 8, a negative oxygen ion generation chamber 10, a vacuum pump 9, a fan 11, a negative oxygen ion buffer chamber 13, a one-way airflow valve 14 and a negative oxygen ion output chamber 15.

[0023] The photovoltaic power generation device 1, the electrolytic cell 5, the vacuum pump 9, and the fan 11 are each connected to the AC / DC inverter device. The first output end of the electrolytic cell 5 is connected to the input end of the oxygen flow monitor 8; the output end of the oxygen flow monitor 8 and the input end of the vacuum pump 9 are connected to the negative oxygen ion generating chamber 10; the negative oxygen ion generating chamber 10 is connected to the negative oxygen ion buffer chamber 13 via the fan 11; and the negative oxygen ion buffer chamber 13 is connected to the negative oxygen ion output chamber 15 via the one-way airflow valve 14.

[0024] In a specific implementation process, the photovoltaic power generation device 1 can use a high-efficiency monocrystalline silicon solar cell panel to convert solar energy into DC power, and then use an AC / DC inverter device to power the electrolytic cell 5, vacuum pump 9, and fan 11.

[0025] The AC / DC inverter device includes a DC / DC inverter 2 and a DC / AC inverter 3. It can use MPPT (maximum power point tracking) technology to stabilize the photovoltaic power generated by the photovoltaic power generation device 1, ensuring that the photovoltaic array always operates at the optimal power output point. It also converts the output voltage of the photovoltaic power generation device 1 into a target voltage, which includes the voltage of the electrolytic cell 5, the voltage of the vacuum pump 9, and the voltage of the fan 11. The voltage of the electrolytic cell 5 and the voltage of the fan 11 can be DC voltages, and the voltage of the vacuum pump 9 can be AC ​​voltages.

[0026] The vacuum pump 9 can adopt an oil-free vortex structure, which first evacuates the interior of the ion generating chamber to ensure that there is no other air source, and then introduces the pure oxygen produced by the electrolytic cell 5.

[0027] The electrolyzer 5 uses proton exchange membrane electrolysis technology. Water molecules undergo an oxidation reaction at the anode to produce oxygen and H⁺. H⁺ passes through the proton exchange membrane to the cathode and combines with electrons to produce hydrogen. Oxygen is transported to the negative oxygen ion generating chamber 10 via the first output end of the electrolyzer 5 and the oxygen flow monitor 8, and negative oxygen ions are generated by the negative oxygen ion generating chamber 10. Among them, the oxygen flow monitor 8 can use a MEMS thermal mass flowmeter, which controls the opening of the proportional valve through a PID algorithm to accurately adjust the pure oxygen flow rate. The negative oxygen ion generating chamber 10 is made of metal or wood, and the surface of the material is sprayed with tourmaline nanoparticles to generate electrons and generate negative oxygen ions with pure oxygen.

[0028] The negative oxygen ions generated in the negative oxygen ion generating chamber 10 are sent by the fan 11 to the negative oxygen ion buffer chamber 13 for stabilization and uniform distribution. After that, they flow through the one-way airflow valve 14 to the negative oxygen ion output chamber 15, which outputs the negative oxygen ions. These negative oxygen ions are high in purity, stable in concentration, and free of pollutants, providing an innovative solution for fields with strict air quality requirements such as medical purification and aerospace life support. Among them, the fan 11 can be a small DC fan using a brushless EC motor with a noise level of ≤35dB, which promotes gas flow within the system, enhances the efficiency of negative oxygen ion generation, and promotes the delivery of the output unit.

[0029] The photoelectric synergistic pure oxygen source negative ion generation system of this embodiment utilizes the light energy generated by the photovoltaic power generation equipment 1 to supply power to electrical equipment such as the electrolyzer 5, and uses the pure oxygen produced by electrolysis of water in the electrolyzer 5 as the source oxygen source, so that the negative oxygen ions finally output are of high purity, stable concentration and free of pollutant doping.

[0030] In a specific implementation, the photoelectric-synergistic pure oxygen source negative ion generation system may further include a control device 20 and a sensor for the negative ion generation chamber (not shown in the figure). The control device 20 is connected to the inverter device, the sensor for the negative ion generation chamber, and the blower 11 (the connection relationship is not shown in the figure). The control device 20 may be connected to the DC / AC inverter 3.

[0031] In a specific implementation process, the negative oxygen ion generating chamber sensor may include a temperature sensor, a humidity sensor, a pressure sensor, and a negative oxygen ion concentration monitoring sensor. The number of each type of sensor can be multiple, evenly distributed on the outside of the cavity wall of the negative oxygen ion generating chamber 10. In this way, the pressure value, temperature value, negative oxygen ion concentration and other sensor data of the negative oxygen ion generating chamber 10 can be obtained. Based on the data obtained by the negative ion generating chamber sensor, the control parameters of the fan 11 are determined; based on the control parameters, the fan 11 is controlled to operate so that the concentration fluctuation range of the negative oxygen ions is within a preset range, tends to be stable, and meets indoor needs. Among them, the control parameters of the fan 11 include the outlet wind pressure of the fan 11 and the air supply volume of the fan 11.

[0032] That is to say, based on the negative oxygen ion concentration value of the negative oxygen ion generating chamber 10, it can be judged whether the negative oxygen ions in the negative oxygen ion generating chamber 10 meet the generation concentration requirements. According to the difference with the expected concentration, temperature, humidity and pressure, the wind pressure of the fan 11 and the air supply volume of the fan 11 can be adjusted to promote the circulation of oxygen in the cavity, increase the contact area between the oxygen molecules and the tourmaline coating, significantly improve the negative oxygen ion generation efficiency, and at the same time maintain the positive pressure of the negative oxygen ion generating chamber relative to the negative oxygen ion buffer chamber.

[0033] In a specific implementation process, the residence time of the negative oxygen ions in the negative oxygen ion buffer chamber 13 can be increased by controlling the closure of the one-way airflow valve 14. In this way, the negative oxygen ions can be fully mixed in the negative oxygen ion buffer chamber 13, making the negative oxygen ions more uniform and more stable.

[0034] In a specific implementation process, the photoelectric coordinated pure oxygen source negative ion generating system of this embodiment may also include an oxygen throttle valve 16, a sensor for photovoltaic power generation equipment 1 (not shown in the figure) and a sensor for a generating chamber 12, and the oxygen throttle valve 16 is connected to a control device 20. The control device 20 is also configured to control the electrolysis current of the electrolytic cell 5, the opening of the oxygen throttle valve 16 and the opening of the oxygen flow monitor 8 according to the sensing data of the sensor 12 for the generating chamber. In this way, closed-loop control of parameters such as the electrolysis current and ion concentration is achieved. Among them, the ion concentration sensor of the sensor 12 for the generating chamber can adopt a parallel plate electrostatic collection structure to monitor the concentration of negative oxygen ions in the generating chamber in real time.

[0035] In a specific implementation process, it was discovered during the research process that the leaf veins of plants form a fractal network through multi-level branching of main veins, lateral veins, and fine veins, which has the following important functions: supporting leaves, transporting water and nutrients (through vascular bundles), and conducting gas exchange for photosynthesis.

[0036] Based on this discovery, it can be known that the leaf veins of plants have a diversion function. Therefore, in this embodiment, an array of bionic leaf vein structures (not shown in the figure) can be set on the inner wall of the negative oxygen ion buffer chamber 13. The bionic leaf vein structure can be used to divert the negative oxygen ions in the negative oxygen ion buffer chamber 13, so that the negative oxygen ions in the negative oxygen ion buffer chamber 13 are more evenly distributed.

[0037] Specifically, the air outlet of the fan 11 can be aligned with the partition between the negative oxygen ion buffer chamber 13 and the negative oxygen ion generating chamber 10. In this way, the negative oxygen ions sent in by the fan 11 can flow along the bionic leaf vein structure on the partition and other internal parts, and gradually flow toward the center of the chamber to avoid excessive flow rate, so that the negative oxygen ion concentration inside the negative oxygen ion buffer chamber 13 is relatively uniform. That is to say, compared with the chamber whose inner wall of the negative oxygen ion buffer chamber 13 is not provided with the bionic leaf vein structure, the flow of negative oxygen ions is slower and more uniform, so that the negative oxygen ions are mixed more evenly in the negative oxygen ion buffer chamber 13.

[0038] It should be noted that other methods can also be used to guide part of the negative oxygen ions delivered by the fan 11 to a target cavity wall of the negative oxygen ion buffer chamber 13, so that the negative oxygen ions delivered by the fan 11 flow preferentially along the bionic leaf vein structure on the target cavity wall, such as adding a guide plate, which will not be explained one by one here.

[0039] Figure 2 This is the second structural diagram of the photoelectric synergistic pure oxygen source negative ion generation system provided by the embodiment of the present invention, such as Figure 2 As shown, the photoelectric coordinated pure oxygen source negative ion generating system of this embodiment is Figure 1 Based on the illustrated embodiments, the technical solution of the present invention is further described.

[0040] See also Figure 2 The photoelectric synergistic pure oxygen source negative ion generation system may further include a hydrogen recovery and processing device 7 and a hydrogen throttle valve 17. The input end of the hydrogen recovery and processing device 7 is connected to the second output end of the electrolyzer 5 through the hydrogen throttle valve 17, and the output end of the hydrogen recovery and processing device 7 is provided with a hydrogen explosion-proof pressure relief valve 19. The hydrogen recovery and processing device 7 can efficiently collect and purify the generated hydrogen, improve the purity of the hydrogen, and ensure safe storage and subsequent utilization.

[0041] Continue to see Figure 2 To further increase the concentration of negative oxygen ions, the photoelectrically coordinated pure oxygen source negative ion generation system can also include an oxygen purification device 6. The first output of the electrolyzer 5 is connected to the input of the oxygen flow monitor 8 via the oxygen purification device 6. The oxygen purification device 6 utilizes a molecular sieve adsorption tower structure, which improves the purity of the generated oxygen through gas-liquid separation, cooling and washing, drying, and catalytic removal of impurities. This results in a purer oxygen concentration entering the negative oxygen ion generation chamber 10, generating a higher concentration of negative oxygen ions. The oxygen purification device is also equipped with an oxygen explosion-proof pressure relief valve 18.

[0042] Continue to see Figure 2 A porous diffusion plate is provided on one side of the negative oxygen ion output chamber 15, so that the negative oxygen ions can flow out of the negative oxygen ion output chamber 15 evenly and output high-concentration negative oxygen ions safely.

[0043] In a specific implementation process, each explosion-proof hydraulic valve and other safety protection devices adopt a multi-level interlock design, which can integrate oxygen concentration monitoring, pressure protection and explosion-proof pressure relief functions, and ensure the safe operation of the system under abnormal working conditions through real-time environmental monitoring and automatic emergency response mechanism.

[0044] Continue to see Figure 2 The photovoltaic-synergistic pure oxygen source negative ion generation system may also include an energy storage device 4. The DC-DC inverter 2 is connected to the fan 11 via the energy storage device 4, and the energy storage device 4 is used to store the electrical energy of the photovoltaic power generation device 1; the DC-AC inverter 3 is connected to the vacuum pump 9. The energy storage device 4 may include a lithium-ion battery pack.

[0045] The photoelectric coordinated pure oxygen source negative ion generation system of this embodiment uses the electricity generated by the photovoltaic power generation equipment 1 to drive the electrolyzer 5 to electrolyze water to produce high-purity oxygen. After purification by the oxygen purification device 6, the pure oxygen is transported to the negative oxygen ion generation chamber 10; the fan 11 promotes air flow, increases the contact between oxygen and the surface of the tourmaline nanoparticle coating, and achieves efficient generation of negative oxygen ions; the generated negative oxygen ions are stabilized in the buffer chamber and evenly released into the target environment through the negative oxygen ion output unit of the porous diffusion plate; during the operation of the system, the intelligent control system monitors the ion concentration and system parameters in real time, and ensures the precise control of the negative oxygen ion concentration by adjusting parameters such as electrolysis power and oxygen flow, thereby realizing the intelligent control function; the hydrogen generated by the system is purified and stored by the recovery and treatment system and can be reused as clean energy, thereby realizing the efficient energy utilization function. In this way, through the coordinated cooperation of photovoltaic power generation and electrolytic oxygen production, the system can ensure stable operation in an off-grid environment, while avoiding secondary pollution of the air by traditional negative ion generators. By setting multiple safety protection devices, the oxygen concentration and system status can be monitored in real time to ensure safe and reliable operation. The present invention organically integrates photovoltaic power generation, electrolytic oxygen production and negative ion generation technologies to achieve a high-purity, high-efficiency and high-stability negative oxygen ion generation function.

[0046] In a specific implementation process, the photoelectric synergistic pure oxygen source negative ion generation system works as follows: 1. System startup phase: Photovoltaic power generation equipment 1 converts solar energy into DC power, which, after voltage stabilization by DC-DC inverter 2, provides power to the electrolyzer 5 and stores excess energy in the lithium-ion battery pack. When the system starts, vacuum pump 9 first evacuates the negative oxygen ion generating chamber 10 to ensure a pure initial environment.

[0047] 2. Oxygen preparation and purification stage: After receiving a stable power supply, electrolyzer 5 begins operating, electrolyzing pure water to produce hydrogen and oxygen. The oxygen undergoes a multi-stage purification process in oxygen purification unit 6, including gas-liquid separation, molecular sieve adsorption, and catalytic oxidation, ultimately yielding medical-grade oxygen with a purity of ≥99.5%. The purified oxygen, after flow regulation by oxygen flow monitor 8, enters negative oxygen ion generator 10.

[0048] 3. Negative oxygen ion generation stage: Within the negative oxygen ion generating chamber 10, electrons are generated based on the thermoelectric effect and spontaneous polarization of the tourmaline nanoparticle coating. These released electrons combine with oxygen molecules to form negative oxygen ions. A small DC blower 11 promotes the circulation of oxygen within the chamber, increasing the contact area between oxygen molecules and the tourmaline coating, significantly improving the efficiency of negative oxygen ion generation. The generated negative oxygen ions then enter the negative oxygen ion buffer chamber 13, where the ion population is stabilized and homogenized.

[0049] 4. Output and control stage: After stabilizing, the negative oxygen ions flow through one-way airflow valve 14 into negative oxygen ion output chamber 15, where they are evenly released into the target environment via the output unit of the porous diffusion plate. The control device 20 monitors the output concentration in real time using an ion concentration sensor and dynamically adjusts parameters such as electrolysis power and oxygen flow rate to maintain the negative oxygen ion concentration within an adjustable range of 1500-5000 ions / cm³.

[0050] 5. Hydrogen recovery and utilization stage: The hydrogen generated by the system is purified by the hydrogen recovery and processing device 7 and then stored. It can be used as clean energy for fuel cell power generation or other industrial purposes, thereby achieving efficient recycling of energy.

[0051] 6. Safety protection measures: The system is equipped with multiple safety protection devices, including: (1) special explosion-proof pressure relief valves are installed at the high-pressure node of the oxygen delivery pipeline and the end of the hydrogen recovery pipeline, respectively. The spring-preloaded structure with a burst pressure of 1.5 times the working pressure is used to ensure millisecond response in the event of overpressure; (2) PT100 temperature sensors (measurement accuracy ±0.5℃) are arranged at key locations such as the PEM electrolyzer 5 and the ion generator chamber, and the power is automatically reduced when the temperature is abnormal; (3) The control system integrates three-level protection programs: primary warning (automatic adjustment when parameters deviate), secondary intervention (partial shutdown when the abnormality persists), and ultimate protection (emergency cutting off all power supplies and starting pressure relief). At the same time, a hardware emergency stop button is set at a conspicuous position on the operation panel to form a full closed-loop safety protection system of "monitoring-warning-disposal".

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
