Abstract

The invention discloses a no-valve reciprocating micro pump. The no-valve reciprocating micro pump comprises an inlet pipe, an upper main pipe, a lower main pipe, a vertical line elastic rod and a horizontal line elastic rod, wherein the upper main pipe and the lower main pipe are connected to form an S-shaped main pipe needed to pump a fluid; the fluid with a speed as a periodic sine function is introduced in the inlet pipe, and drives the line elastic rods to deform; and a certain inhibition effect on the fluid in the pipe is formed by the deformation of the line elastic rods, so that the net pumping flow from left and right is continuously increased. The no-valve reciprocating micro pump has the advantages of simple structure, no need of external voltage, good stability, low cost and convenience for mass production, and can finish high-efficiency fluid pumping.
