[0030] The fresh air component 6 includes a high-efficiency antibacterial filter cotton 601, a high-efficiency air filter plate 602 and an air purification box 603 arranged inside the frame 501. The high-efficiency air filter plate 602 is located on the top of the high-efficiency antibacterial filter cotton 601, and the air purification box 603 is located on the top of the high-efficiency air filter plate 602. The exhaust end of the air purification box 603 is connected to the air inlet end of the dual oxygen source compressor 2, and the UV sterilization light strip 604 is arranged at the bottom of the air purification box 603.

[0031] In this embodiment: When the outside air enters the oxygen frame assembly 5, it first contacts the high-efficiency antibacterial filter cotton 601 in the fresh air assembly 6. The high-efficiency antibacterial filter cotton 601 can intercept larger particles of impurities and some bacteria in the air through its special fiber structure and antibacterial material, preventing these impurities and bacteria from entering the subsequent oxygen production system, thereby reducing damage to the dual oxygen source compressor 2 and the molecular sieve system, and also helping to maintain the hygiene of the oxygen space. Then, the air passes through the high-efficiency air filter plate 602. The high-efficiency air filter plate 602 usually has a finer pore structure, which can further filter out tiny particles in the air, such as dust, pollen, etc., to ensure that the air entering the dual oxygen source compressor 2 is purer. Then, the air passes through the UV sterilization light strip to effectively kill bacteria and viruses. , fungi and other microorganisms, and then enter the air purification box 603. The air purification box 603 contains adsorbents, catalysts and other substances, which can effectively remove odors, harmful gases, etc. in the air and deeply purify the air. This series of filtering and purification processes, the treated clean air is discharged from the exhaust end of the air purification box 603, and is transported to the air inlet end of the dual oxygen source compressor 2, providing a high-quality air source for the subsequent oxygen production and pressurization process. In short, the oxygen frame assembly 5, through the synergistic effect of its internal high-efficiency antibacterial filter cotton 601, high-efficiency air filter plate 602 and air purification box 603, comprehensively pre-treats the air entering the compressed oxygen concentrator, provides a clean and safe air environment for the oxygen production process, and ensures the efficient and stable operation of the compressed oxygen concentrator.

[0032] Specifically, such as Figure 3 As shown, a ventilation bottom groove 502 is opened on the bottom side of the interior of the frame 501 , and the interior of the ventilation bottom groove 502 is snap-fitted with the high-efficiency antibacterial filter cotton 601 .

[0033] Specifically, such as Figure 3 As shown, a partition groove 503 is provided in the middle of the frame 501 , the partition groove 503 is communicated with the bottom groove, and the interior of the partition groove 503 is engaged with the high-efficiency air filter plate 602 .

[0034] Specifically, such as Figure 3 As shown, a top groove 504 is provided on the top side of the frame 501 , the top groove 504 is communicated with the partition groove 503 , and the interior of the top groove 504 is engaged with the air purification box 603 .

[0035] In this embodiment, the outside air first enters the ventilation bottom groove 502. Since the high-efficiency antibacterial filter cotton 601 is clamped in the ventilation bottom groove 502, when the air passes through, the high-efficiency antibacterial filter cotton 601 uses its special fiber structure and antibacterial material to intercept larger particles of impurities and some bacteria in the air, thereby preliminarily purifying the air. Then, the air flows from the ventilation bottom groove 502 into the partition groove 503. The high-efficiency air filter plate 602 in the partition groove 503 further filters out tiny particles in the air, such as dust and pollen, making the air purer. Then, the air enters the top groove 504 from the partition groove 503. The air purification box 603 in the top groove 504 removes odors, harmful gases, etc. in the air through its internal adsorbent, catalyst and other substances, thereby deeply purifying the air. The air purified through these three levels of filtration is discharged from the exhaust end of the air purification box 603 and is transported to the intake end of the dual oxygen source compressor 2, providing a high-quality air source for the subsequent oxygen production and pressurization processes, thereby ensuring the efficient and stable operation of the compressed oxygen concentrator.

[0036] Specifically, such as Figure 6 As shown, power supplies 7 are provided on both sides of the top of the frame 501 , and the power supplies 7 are located at the bottom of the housing 3 .

[0037] Specifically, such as Figure 6 As shown, a positioning frame 8 is provided on the top of the power supply 7 , and the positioning frame 8 is bolted to the top of the frame 501 .

[0038] In this embodiment, the power supply 7 provides a stable power source for the operation of the entire compressed oxygen concentrator, ensuring the normal operation of the equipment. The provision of the positioning frame 8 enables the power supply 7 to be firmly mounted on the frame 501, preventing the power supply 7 from loosening or shifting due to vibration and other reasons during the operation of the equipment, thereby ensuring the stability of power supply. In addition, the power supply 7 is disposed on both sides of the top of the frame 501, making full use of the space inside the equipment, making the structure of the entire compressed oxygen concentrator more compact, reducing the space occupied by the equipment, and facilitating line connection and maintenance.

[0039] Specifically, such as Figure 5 As shown, the frame 501 is integrally formed by stamping, and the outer side of the ventilation bottom groove 502, the bottom of the partition groove 503 and the inside of the top groove 504 are all provided with flow grooves.

[0041] In this embodiment: the frame 501 formed by integral stamping has a high structural strength, can withstand various stresses during the operation of the equipment, and ensure the stability and reliability of the equipment. The setting of the circulation groove can make the air circulate more smoothly inside the frame 501, thereby improving the efficiency of air filtration and purification. The bolted sealing plate 9 is convenient for disassembly and installation, and it is convenient for maintenance and replacement of components inside the frame 501. The setting of the arc-shaped air inlet pipe 10 can make the air enter the high-efficiency antibacterial filter cotton 601 more smoothly, reduce the resistance to air flow, and improve the effect of air filtration. At the same time, the arc-shaped air inlet pipe 10 can also play a certain buffering role, preventing external dust and impurities from directly impacting the high-efficiency antibacterial filter cotton 601, thereby extending the service life of the filter cotton.

[0042] Working principle: During the use of the compressed oxygen concentrator, the outside air first enters the interior of the frame 501 through the arc-shaped air inlet pipe 10, and the air first contacts the high-efficiency antibacterial filter cotton 601. Since the high-efficiency antibacterial filter cotton 601 is clamped in the ventilation bottom groove 502, when the air passes through, its special fiber structure and antibacterial material intercept the larger particles of impurities and some bacteria in the air, and perform preliminary purification. Then, the air flows from the ventilation bottom groove 502 into the partition groove 503, and the high-efficiency air filter plate 602 in the partition groove 503 further filters the tiny particles in the air, such as dust, pollen, etc., to make the air purer. Then, the air enters the top groove 504 from the partition groove 503, and the UV sterilization light strip effectively kills various microorganisms such as bacteria, viruses, fungi, etc. in the air. Then, the air The air then enters the air purification box 603, which contains adsorbents, catalysts and other substances. The air purification box 603 in the top groove 504 removes odors, harmful gases and the like in the air through its internal adsorbents, catalysts and other substances, and deeply purifies the air. The air purified through these three levels of filtration is discharged from the exhaust end of the air purification box 603 and is transported to the air inlet end of the dual oxygen source compressor 2. The dual oxygen source compressor 2 starts working. Due to the dual compressor design, it can simultaneously perform oxygen production and pressurization operations. The dual compressors work together to improve the oxygen production efficiency and pressure output capacity. The compressed air enters the subsequent oxygen production process, and high-purity oxygen is separated through devices such as the molecular sieve system, ultimately providing users with high-quality oxygen supply.
