Double ceramic chip piezoelectric pump

The utility model discloses a double ceramic chip piezoelectric pump which comprises upper and lower shells, a middle shell, upper and lower valve brackets, upper and lower transduction plates, upper and lower valve plates, two seal rings and a divider resistance. Two working chambers are defined by the surfaces, where metal base materials are located, of the two transduction plates and the surfaces of the valve plates, and external power sources of the metal base materials of the two transduction plates have same polarity, and axial leads of the two transduction plates are arranged from top to bottom in a concentric mode. The double ceramic chip piezoelectric pump has the advantages that the structure is compact, flow pressure is multiplied compared with that of a single ceramic chip piezoelectric pump, the service life of piezoelectric ceramic chips are prolonged, and the regulation performance of a piezoelectric pump is effectively improved through a bleeder circuit.
