An airflow channel module for oxygen concentrator is provided, including at least two molecular sieves, an oxygen storage unit, an air expelling unit, an air channel module, an air intake/expel module, and an automatic valve. The airflow channel module utilizes the oxygen storage channel and the air channel hidden inside the air channel module, the air intake channel, the air expelling channel and the air supply channel hidden in the air intake/expel module, and the automatic valve to control the flow of the air, oxygen and the nitrogen. By modularizing the airflow channel and eliminating the exposed hoses in conventional oxygen concentrator, the airflow channel module simplifies the assembly and maintenance of the oxygen concentrator.
