A miniature pump includes a driving unit and an airflow control unit, which includes a bladder supporter, a compression unit, a valve base and an output valve. The compression unit has multiple intake valves and multiple bladders, each intake valve covers the corresponding intake through hole, each intake through hole is surrounded by a circular wall, wherein the circular wall is disposed on a bottom surface of the corresponding intake valve or a top surface of the corresponding bladder supporter. The valve base is arranged over the compression unit, and the valve base has multiple output through holes aligned with the bladders respectively. When the bladder is compressed, air inside the bladder is output via the output through hole and the output valve. When the bladder is decompressed, external air is introduced into the bladder via the intake through hole and the intake valve.
