The utility model provides an electricity is folded and is piled the mixing pump, and by a piezoelectric stack pump, the 2nd piezoelectric stack pump and hybrid tube are formed, the hybrid tube is placed in between a piezoelectric stack pump and the 2nd piezoelectric stack pump, and the hybrid tube is equipped with T type pipeline, and T type pipeline both ends link to each other with first export check valve and second export check valve respectively, the during operation, the pulse signal who exerts different frequency and amplitude to a piezoelectric stack and the 2nd piezoelectric stack respectively, a liquid gets into first pump chamber through first entry check valve to go into T type pipeline through first export bill to the valve flow, B liquid passes through the the second entrance check valve and gets into the second pump chamber, and goes into T type pipeline through the second export bill to the valve flow, a liquid and the B liquid hybrid tube that flows after abundant mixture in T type pipeline. The utility model discloses utilize piezoelectric stack as the driver to the defeated outflow and the power output of piezoelectric pump is improved, the bigger power of mixing can be provided for polymer density solution and thick liquid's mixture.
