| description | The invention discloses an ultrasonic micro-flow pump which comprises a liquid outlet pipe and a pump body. A micro-control pipeline and a piezoelectric cavity are arranged in the pump body, and the piezoelectric cavity is annularly arranged on the micro-control pipeline; the piezoelectric cavity is internally provided with piezoelectric ceramic, the piezoelectric ceramic is connected to an external power supply through an electrode, the piezoelectric ceramic acts on the micro-control pipeline, the liquid outlet pipe is inserted into the micro-control pipeline in a penetrating manner, and the micro-control pipeline is arranged on the annular side of the liquid outlet pipe in a wrapping manner; the vibration frequency of the piezoelectric ceramic can be controlled by adjusting the current of the external power supply, and then the extrusion amount of the material is controlled, so that the controllable range is large, the extrusion amount can be controlled within a very small numerical value, and the precision |
