1. piezoelectric pump that is used for pumping fluid, described pump comprises:

  • Housing;

    Be positioned at the actuator of housing, the voltage that wherein is applied to actuator impels actuator to apply active force;

    Primary diaphragm near described actuator;

    Be positioned at the piston assembly of housing, described piston assembly is removable between at least one primary importance and second place;

    The first-class body cavity that limits by described housing, primary diaphragm and piston assembly;

    Be positioned at the connection fluid that is used for primary diaphragm is connected to piston assembly of first-class body cavity;

    Second fluid chamber that limits by described housing and piston assembly;

    The inlet valve that is communicated with second fluid chamber;

    The outlet valve that is communicated with second fluid chamber;

    Wherein, the active force that is applied by described actuator makes the primary diaphragm displacement, force the connection fluid that piston assembly is moved to the described second place from described primary importance, and the volume of mobile change second fluid chamber of piston assembly between the primary importance and the second place, thereby make fluid enter second fluid chamber and discharge from second fluid chamber by outlet valve by inlet valve.
