The base 1002 is mounted on the bottom plate 4 of the oxygen concentrator. A U-shaped plate 1003 is installed on the base 1002. A wet curtain 1004 is installed in the U-shaped plate 1003. The wet curtain 1004 is directly opposite to the air outlet of the fan 1001 and the heat dissipation pipe 8. A water retaining wall is installed at one end of the U-shaped plate 1003. Plate 1005, a dripping pipe 1006 is installed between the water retaining plate 1005 and the U-shaped plate 1003, the dripping pipe 1006 is connected to the liquid outlet pipe 608, a small hole is opened on the outer surface of the dripping pipe 1006, and a dripping pipe is installed in the small hole, a water trough is opened between the lower bottom edge of the wet curtain 1004 and the U-shaped plate 1003, a return pipe 1007 is installed on one side of the U-shaped plate 1003, the return pipe 1007 is connected to the water trough, the return pipe 1007 is connected to the cleaning device 11 pipeline, and the fan 1001 is connected to the control system.

[0029] When water enters the drip pipe 1006, the water slowly drips from the drip pipe on the drip pipe 1006 into the wet curtain 1004, and the fan 1001 blows the nitrogen and oxygen sent by the third reversing valve 907 onto the wet curtain 1004, so that the water on the wet curtain 1004 evaporates and absorbs heat, forming cold wind that blows toward the heat dissipation pipe 8, and the excess water will flow into the water tank and flow into the water pump through the reflux pipe 1007, and the water pump will send the water into the water tank 1101.

[0030] The cleaning device 11 includes a water tank 1101, which is installed on the metal protective shell 701. A water pump is installed inside the water tank 1101, and the water inlet of the water pump is connected to the return pipe 1007. A solenoid valve 1102 is installed on one side of the water tank 1101, and a water outlet pipe 1103 is installed at one end of the solenoid valve 1102. One end of the water outlet pipe 1103 is installed at one end of the rotating shaft 6042. The water pump and the solenoid valve 1102 are connected to the control system. When the oxygen generator stops being used, the solenoid valve 1102 is controlled to open, and the water in the water tank 1101 enters the rotating shaft 6042 through the water outlet pipe 1103, and is sprayed out through the water outlet holes on the outer surface of the rotating shaft 6042 to flush out the impurities accumulated on the dust screen 6041 and the scraper 6045. The flushed water flows from the short pipe 605 to the first reversing valve 606, and the first reversing valve 606 switches to the liquid outlet pipe 608. The filter net in the liquid outlet pipe 608 filters out the impurities in the water, and the filtered water enters the drip pipe 1006.

[0031] Working principle of the present invention: During operation, the air compressor 704 is started manually through the touch screen 3, and the air compressor 704 draws air in through the air inlet pipe 5. When the air enters the dust removal and sterilization box 601, the ultraviolet lamp 603 removes biological pollutants such as bacteria in the air, and the sterilized air is blown to the fan blades 6043, and the fan blades 6043 drive the shaft 6042 to rotate, and the shaft 6042 drives the dustproof net 6041 to rotate. When the dustproof net 6041 rotates, it rubs against the rubber rod 6044 to form static electricity, which adsorbs impurities such as dust and particles in the air on the outside of the dustproof net 6041, scraping Plate 6045 scrapes off the impurities adsorbed on the dustproof net 6041 to prevent the rubber rod 6044 from contacting the accumulated dust and affecting the formation of static electricity. The air after dust removal and sterilization is delivered into the short tube 605 through the rotation of the fan blade 6043. The first reversing valve 606 is controlled to open the passage of the first air outlet pipe 607. The air after dust removal and sterilization enters the air inlet of the air compressor 704 through the first air inlet pipe 703. The air compressor 704 compresses the air and delivers it into the second air outlet pipe 702 from the air outlet of the air compressor 704. The air enters the heat dissipation pipe 8 from the second air outlet pipe 702.

[0032] When the air enters the heat dissipation pipe 8, the fan 1001 blows the nitrogen and oxygen sent by the third reversing valve 907 onto the wet curtain 1004, causing the water on the wet curtain 1004 to evaporate and absorb heat, forming cold wind that blows toward the heat dissipation pipe 8, dissipating the air in the heat dissipation pipe 8, causing the compressed air temperature to drop rapidly, and entering the air inlet of the first adsorption device 902 through the second reversing valve 906.

[0033] When air enters the first adsorption device 902, the molecular sieve in the first adsorption device 902 adsorbs nitrogen in the air, and a part of the separated oxygen enters the fourth reversing valve 913 through the first oxygen inlet pipe 910, and enters the oxygen storage tank 909 through the oxygen outlet pipe 908. After the oxygen is reduced in pressure by the pressure reducing valve, it is sent to the humidification cup 12. The humidified oxygen is sent to the patient's oxygen supply pipe. Another part of the oxygen enters the second oxygen inlet pipe 911 through the connecting pipe 912, and enters the first oxygen inlet pipe 911 through the second oxygen inlet pipe 911. In the second adsorption device 903, the nitrogen in the molecular sieve after being adsorbed for a period of time is flushed into the third reversing valve 907, and the third reversing valve 907 sends the nitrogen and oxygen to the air inlet of the fan 1001. After the molecular sieve in the first adsorption device 902 is adsorbed for a period of time, the second reversing valve 906 will switch to the air inlet pipe of the second adsorption device 903, the third reversing valve 907 will switch to the air outlet pipe of the first adsorption device 902, and the fourth reversing valve 913 will switch to the second oxygen inlet pipe 911, and the cycle will continue.

[0034] When the air compressor 704 generates vibration during operation, the air compressor 704 drives the upper plate 7051 to press downward, the guide rod 7052 on the upper plate 7051 slides downward in the support block 7053, the pressure block 7057 on the support rod 7058 presses the sliding plate 7056 to move downward, the sliding plate 7056 compresses the spring 7055, and the vibration of the air compressor 704 is transmitted to the spring 7055, and the spring 7055 absorbs the vibration, thereby reducing the vibration of the air compressor 704.

[0035] When the oxygen generator stops using, the solenoid valve 1102 is controlled to open, and the water in the water tank 1101 enters the rotating shaft 6042 through the water outlet pipe 1103, and is sprayed out through the water outlet hole on the outer surface of the rotating shaft 6042 to flush out the impurities accumulated on the dust screen 6041 and the scraper 6045. The flushed water flows from the short pipe 605 to the first reversing valve 606, and the first reversing valve 606 switches to the liquid outlet pipe 608. The filter net in the liquid outlet pipe 608 filters out the impurities in the water, and the filtered water enters the drip pipe 1006. The water slowly drips from the drip pipe on the drip pipe 1006 into the wet curtain 1004, so that the surface of the wet curtain 1004 is moistened, and the excess water flows from the wet curtain surface 1004 to the water tank, and flows to the water pump through the reflux pipe 1007, and the water pump sends the water into the water tank 1101.
