Abstract: An oxygen generator includes an adsorption tower and an exhaust muffler. The adsorption tower includes a loading cavity for loading a molecular sieve, and a nitrogen exhaust port in communication with the filling cavity; the exhaust muffler includes a gas inlet and a gas outlet, the gas inlet being in communication with the nitrogen exhaust port; and the exhaust muffler is configured to only allow a gas to flow unidirectionally from the gas inlet to the gas outlet. In the oxygen generator, the exhaust muffler is arranged at the nitrogen exhaust port of the adsorption tower, and the exhaust muffler is configured to only allow a gas to flow unidirectionally from the gas inlet to the gas outlet.
