Patent ID: 8870356

Claim:
A micro-ejector, comprising: an ejection device including a passage for ejecting fluid contained therein, and a piezoelectric actuator providing a driving force for ejecting fluid; a mounting plate including a passage for providing fluid to the ejection device formed therein, a mounting groove on which the ejection device is mounted, and an elastic member formed on one side wall of the mounting groove and enabling the ejection device to be closely fitted to the mounting groove, the elastic member protruding against the ejection device to thereby push the ejection device toward another side wall of the mounting groove; and a connection member formed on the mounting plate, and adopted for connecting the piezoelectric actuator to an external power source, the ejection device being removable from the mounting groove, and the connection member being selectively connected to or disconnected from the piezoelectric actuator depending on whether the ejection device is mounted on or removed from the mounting groove.
