Abstract
A droplet generating method includes: providing a micro-pipe for dispensing a first liquid and a container containing a second liquid; providing a moving and locating device for positioning the micro-pipe over the container; providing a liquid driving device connecting to the micro-pipe through a connecting tube; providing a vibrating equipment connected to the micro-pipe for vibrating the micro-pipe; forming a relative periodic vibration between the micro-pipe and the container so that the outlet end of the micro-pipe is displaced to touch the second liquid in the container during a relative periodic vibration; and dispensing the first liquid in the micro-pipe out from the outlet end of the micro-pipe during the relative periodic vibration to generate a plurality of droplets of the first liquid in the second liquid which is induced by a force of the second liquid imposed on the first liquid at the outlet end.
