Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See appendix Figure 1 To be continued Figure 4 An oxygen generator that outputs high-pressure oxygen and high-pressure air includes: a high-pressure air system, an oxygen generation system, a circuit control system (400), and a booster system; the high-pressure air system includes: an air compressor (101) and a high-pressure air storage tank (102), a pressure regulating tee (103) is connected to the high-pressure air storage tank (102), a pressure regulating valve (104) is connected to one end of the pressure regulating tee (103), the pressure regulating valve (104) is connected to the oxygen generation system, and the other end of the pressure regulating tee (103) is connected to the high-pressure air outlet (105); the oxygen generation system is connected to the booster system, and the circuit control system (400) is electrically connected to the high-pressure air system, the oxygen generation system, and the booster system respectively.

[0022] An oxygen generator that outputs high-pressure oxygen and high-pressure air includes a high-pressure air system, an oxygen generation system, a circuit control system, and a pressurization system. The high-pressure air system outputs high-pressure air and also supplies the required compressed air to the oxygen generation system. The oxygen generation system separates oxygen from the air using molecular sieve adsorption technology to generate high-purity oxygen, which is then pressurized to a set pressure by the pressurization system. The high-pressure air system includes an air compressor and a high-pressure air storage tank. The high-pressure pump compresses and delivers air, storing it in the high-pressure air storage tank. The high-pressure air storage tank stores and stably supplies high-pressure air. A pressure regulating tee connected to the high-pressure air storage tank can split the high-pressure air, with one path entering the oxygen generation system through a pressure regulating valve. One path serves as the raw material gas, while another path outputs it through a high-pressure air outlet for external use. A pressure regulating valve precisely controls the pressure input to the oxygen generation system, ensuring the molecular sieve operates efficiently and stably, and preventing excessively high or low gas pressure entering the oxygen generation system, thus guaranteeing oxygen purity and production efficiency. The oxygen generation system is connected to a booster system; the oxygen separated by the oxygen generation system enters the booster system for secondary pressurization to reach the required output pressure. The boosted high-pressure oxygen is then output through a dedicated oxygen outlet. The circuit control system can monitor and regulate the operating status of the high-pressure air system, oxygen generation system, and booster system in real time, ensuring the coordinated and stable operation of each system. Preset programs enable start / stop control, pressure regulation, and fault alarm functions.

[0023] Preferably, the pressurization system includes a booster pump (300) and a high-pressure oxygen storage tank (301), wherein the high-pressure oxygen storage tank (301) is disposed at the output end of the booster pump (300); the oxygen generation system includes an oxygen generation module (200) and an oxygen generation solenoid valve (201), wherein the oxygen generation solenoid valve (201) is connected to the pressure regulating valve (104) through a water removal filter (202), the oxygen generation solenoid valve (201) is connected to the oxygen generation module (200), and the oxygen generation module (200) is connected to the booster pump (300).

[0024] Thus, the pressurization system includes a booster pump and a high-pressure oxygen storage tank. The booster pump further compresses the oxygen generated by the oxygen generating module and sends it to the high-pressure oxygen storage tank for storage, ensuring stable output pressure and meeting the high-purity oxygen requirements for medical or industrial use. The oxygen generating system includes an oxygen generating module and an oxygen generating solenoid valve. The oxygen generating solenoid valve is connected to a pressure regulating valve through a water removal filter to precisely control the start, stop, and direction of airflow, ensuring that the compressed air entering the oxygen generating module is clean and dry, improving the service life of the molecular sieve and the purity of the oxygen. The oxygen generated by the oxygen generating module is pressurized by the booster pump and stored in the high-pressure oxygen storage tank, which allows for buffered storage of oxygen.

[0025] Preferably, there are two sets of air compressors (101), and the two sets of air compressors (101) are connected in parallel. An air check valve (106) is provided between the air compressor (101) and the high-pressure air storage tank (102). A condenser (107) is provided between the air check valve (106) and the air compressor (101). A fan (108) is provided on the condenser (107). An exhaust tee (109) is provided between the condenser (107) and the check valve (106). An exhaust solenoid valve (110) is connected to the exhaust tee (109).

[0026] In this way, the two sets of air compressors operate in parallel, serving as backups for each other, which improves the continuity and stability of the system's air supply. The air check valve prevents high-pressure air from flowing back, ensuring the safe operation of the air compressors. The condenser, in conjunction with the fan, effectively reduces the temperature of the compressed air, causing the moisture in the air to condense and precipitate out quickly.

[0027] Preferably, an oxygen filter (302) is provided between the oxygen generating module (200) and the booster pump (300).

[0028] In this way, the oxygen filter installed between the oxygen generating module and the booster pump can further remove trace amounts of moisture and impurities from the oxygen, ensuring that the gas entering the booster pump is clean and dry.

[0029] Preferably, an oxygen venting tee (303) is provided between the booster pump (300) and the high-pressure oxygen storage tank (301), one end of the oxygen venting tee (303) is connected to an oxygen venting solenoid valve (304), and an oxygen check valve (305) is provided between the oxygen venting tee (303) and the high-pressure oxygen storage tank (301).

[0030] In this way, the oxygen venting tee and the oxygen venting solenoid valve work together to vent the residual low-purity oxygen in the pipeline during the initial start-up of the booster pump or when it stops, ensuring the stability of the oxygen purity in the high-pressure oxygen storage tank; the oxygen check valve prevents high-pressure oxygen backflow and protects the safe operation of the booster pump; and the high-pressure oxygen storage tank can buffer and store oxygen.

[0031] Preferably, an air pressure controller (111) is provided on the high-pressure air storage tank (102), and an oxygen pressure controller (306) is provided on the high-pressure oxygen storage tank (301). The circuit control system (400) is electrically connected to the air pressure controller (111) and the oxygen pressure controller (306) respectively. The circuit control system (400) is electrically connected to the exhaust solenoid valve (110), the oxygen exhaust solenoid valve (304), the oxygen generation solenoid valve (201), and the pressure regulating valve (104).

[0032] In this way, the air pressure controller and oxygen pressure controller monitor the pressure in their respective storage tanks in real time. When the set upper limit is reached, the circuit control system automatically shuts down the air compressor or oxygen generation module, and restarts it when the pressure falls below the set lower limit, thus achieving stable control of the gas supply pressure. Simultaneously, the circuit control system links the exhaust solenoid valve, oxygen exhaust solenoid valve, and pressure regulating valve according to the pressure status, ensuring stable gas pressure and compliant purity during system start-up, shutdown, and operation, thereby improving overall operational safety and automation. During system operation, high-pressure air is precisely reduced in pressure by the pressure regulating valve before entering the oxygen generation module. The opening and closing of the oxygen generation solenoid valve is controlled by the circuit control system based on oxygen demand and system pressure status, ensuring precise matching between oxygen generation and delivery.

[0033] Preferably, the high-pressure air system, oxygen generation system, circuit control system (400) and pressurization system are housed in a cabinet (500), and a working surface (501) is provided on the upper part of the cabinet (500).

[0034] In this way, the cabinet can accommodate the compressed air system, oxygen generation system, circuit control system (400) and pressurization system, and provide the equipment with a neat appearance and safety protection. The working surface on the upper part of the cabinet can be used to place other equipment or items for convenient operation.

[0035] Preferably, the bottom of the cabinet (500) is provided with casters (502).

[0036] In this way, the casters facilitate the movement and positioning of the entire device, making it especially suitable for usage scenarios that require frequent position adjustments, thereby improving the flexibility and ease of operation of the equipment.

[0037] Preferably, the circuit control system (400) is connected to an AC contactor (401) and a time relay (402).

[0038] In this way, AC contactors are used to control the power supply to high-power components, ensuring smooth start-up and shutdown of equipment such as air compressors and booster pumps, and avoiding current surges. Time relays, on the other hand, implement timing control for system start-up, shutdown, venting, and oxygen removal operations, ensuring that each step is executed according to a preset logical sequence, improving the coordination and reliability of system operation, and further enhancing the automation level and safety performance of the entire machine. The time relays work in conjunction with the circuit control system, and can be programmed with delayed start-up and step-by-step operation to avoid pressure fluctuations and sudden increases in power load caused by the simultaneous operation of multiple components.

[0039] Preferably, a second high-pressure oxygen storage tank (307) is also connected in series on the high-pressure oxygen storage tank (301).

[0040] In this way, the two high-pressure oxygen storage tanks effectively improve oxygen storage capacity and supply stability, meeting the demand for continuous high-flow oxygen. Simultaneously, through two-stage pressure equalization and buffering, the system's start-up and shutdown frequency is reduced, extending equipment lifespan. Furthermore, multiple high-pressure oxygen storage tanks can be added in parallel or series to expand storage capacity and adapt to oxygen demands under different operating conditions.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions are all considered to be within the protection scope of the present utility model.
