: The author has found the sucking process outflow phenomenon existing in piezoelectric pump during the outflow experiment. To explain the reason of outflow in sucking process, the fluid-structure interaction model of piezoelectric vibrator, fluid and check valve is founded. The simulation analysis turns out that the pump chamber pressure increases sharply in the later of sucking process because of the flow inertia, which is the root cause of sucking process outflow. The output flow should include two part, bulk flow and inertial flow, which will provide theoretical reference to piezoelectric pump outflow control.
