摘要:
Disclosed is an ultrasonic piezoelectric pump in which a piezoelectric pump is integrated with a fluid pipe without a check valve so that the structure can be simplified. The pump includes a fluid pipe having a hollow part formed therein to permit a fluid to flow from a fluid source, a piezoelectric actuator inserted into the hollow part and including a piezoelectric device and a plurality of fluid holes, a controller connected to a lead wire to apply a driving power to the piezoelectric device, and a tapered nozzle inserted into the hollow part in front of the piezoelectric actuator and tapered forward and downwardly.
