摘要

A miniature pump includes a cylinder, a piston module, a driving module and a wall body. The cylinder has a first end and a second end opposite to each other along a direction. The piston module is accommodated in the cylinder. The piston module has at least one pumping chamber structure protruded towards the second end, and the pumping chamber structure is able to extend or retract along the direction. The driving module is located at the second end and connected to the pumping chamber structure, configured to drive the pumping chamber structure to extend or retract along the direction. The wall body at least partially surrounds a position of the pumping chamber structure near the first end, and is located between the cylinder and the pumping chamber structure.
