The molecular sieve inside the fixing pipe 4 needs to be replaced regularly. When replacing the molecular sieve, the screws on the surface of the foot pad 201 can be removed, the extension pipe 302 is separated from the exhaust pipe of the compressor 102, and the rubber plug 701 is pulled out of the through pipe 601. In this way, workers can take out the four fixing pipes 4 from the oxygen generator main body 1 at one time. The cover plate 6 is threadedly connected to the fixing pipe 4. After the cover plate 6 is taken out, the fixing pipe 4 is inverted, and the molecular sieve inside the fixing pipe 4 can pour out from the top of the fixing pipe 4. A spiral blade 5011 is fixedly installed on the outer end surface of the connecting rod 501 at the upper end of the knob 5. At this time, the worker can rotate the knob 5.
