[0002] At present, with the rapid development of modern industry, the continuous acceleration of work pace and the continuous improvement of working conditions, people often work and live in relatively closed rooms to reduce the impact of external air pollution. As the ventilation in the room is extremely poor, people work and live for a long time under such conditions, and the oxygen content in the environment will inevitably decrease. Oxygen is the first need for human life activities. People living in such an oxygen-deficient environment may eventually experience headaches, dizziness, memory loss and other phenomena. In severe cases, it may lead to decreased function of organs such as the heart, brain, and lungs, and decreased immunity. The split oxygen generator currently used is basically composed of an outdoor unit and an indoor unit. The outdoor unit is mainly placed outdoors to concentrate the oxygen in the air and transport oxygen to the indoor unit for indoor personnel.

[0021] By adopting the above technical solution, the dustproof net 13 is cleaned by using the roller brush 35 .

[0022] Gears 37 are fixedly mounted on both ends of the two roller brushes 35 , and two symmetrically distributed tooth plates 36 are fixedly mounted in the two rainproof covers 2 , and the gears 37 mesh with the corresponding tooth plates 36 .

[0023] By adopting the above technical solution, while the roller brush 35 slides, the gears 37 at both ends thereof are engaged with the toothed plates 36 to drive the roller brush 35 to rotate to clean the dustproof net 13.

[0024] Reciprocating screws 34 are rotatably installed on both sides of the two rainproof covers 2. Slide blocks 341 are slidably clamped in the thread grooves of the four reciprocating screws 34.

[0033] By adopting the above technical solution, the worm 81 drives the worm wheel 82 to rotate, and the worm wheel 82 drives the dust suction fan 7 to rotate.

[0034] Working principle: The external air enters the compressor 5 through the air inlet 12 and the filter 4 for compression. The dust screen 13 in the air inlet 12 will filter out the large particles of impurities in the air, and the filter 4 will filter out the tiny impurities in the air. The compressed air enters the oxygen generator 6 to generate oxygen, and is transported into the indoor unit through the corrugated hose 11. When there are many impurities adsorbed on the dust screen 13, the driving motor 31 drives the two rotating wheels located in the main body through the synchronous belt 33 and the synchronous wheel 32. The multithread rod 34 and the worm 81 rotate synchronously. The reciprocating screw rod 34 rotates, so that the slider 341 drives the connecting rod 342 to slide in its threaded groove, and the connecting rod 342 drives the roller brush 35 to slide back and forth along the dustproof net 13. While the roller brush 35 slides, the gears 37 at both ends of the roller brush 35 engage with the toothed plate 36 to drive the roller brush 35 to rotate to clean the dustproof net 13. At the same time, the worm 81 drives the worm wheel 82 to rotate, and the worm wheel 82 drives the dust suction fan 7 to rotate, so that the cleaned impurities are blown out of the rain cover 2.
