The intake sound of the compressor is silenced by the aluminum alloy elbow 106 in the intake muffler cavity 105. Since the aluminum alloy housing 101 of the intake muffler has a good sound insulation effect, the overall noise is further reduced. For the exhaust silencing device of this small molecular sieve oxygen generator, by setting the aluminum alloy housing 103 of the exhaust muffler, when the device is in use, multiple sound-absorbing sponges 111 are arranged in the exhaust muffler cavity 109 to absorb the generated noise.

For the exhaust silencing device of this small molecular sieve oxygen generator, a butt plate 102 is set to butt and divide the aluminum alloy housing 101 of the intake muffler and the aluminum alloy housing 103 of the exhaust muffler. At the same time, the reinforcing rods 112 arranged inside the butt plate 102 greatly enhance its strength, making it stronger when in use.
