Abstract
A micro pump having noise-reduced pressure-releasing structure includes a convergence plate, a valve sheet, a chamber plate, and a micro pump. The convergence plate has a convergence outlet and a discharge outlet. The valve sheet has a valve hole and a discharge recessed portion. The chamber plate has a recessed hole, a fluid determine hole, fluid through holes, and a receiving trough. The micro pump is in the receiving trough. During operation of the micro pump, the fluid is firstly transmitted to the fluid through hole and the fluid determine hole to push the valve sheet, and the fluid determine hole pushes the discharge recessed portion to block the discharge outlet. Then, since the pressure of the fluid at the fluid through hole pushes the valve sheet, the fluid flows through the valve hole so as to be discharged out from the convergence outlet.
