Patent ID: 8747080

Claim:
A fluid pump comprising: an actuator including a disk-shaped diaphragm and a piezoelectric element provided on the disk-shaped diaphragm; a planar section disposed such that the planar section faces the actuator while being in proximity to the actuator; at least one center vent is disposed in a portion at or in an area adjacent to a center of an actuator facing area of the planar section that faces the actuator; a diaphragm support frame which retains the diaphragm with a gap between the diaphragm support frame and an outer circumference of the diaphragm; a conductive connecting portion provided between diaphragm support frame and the diaphragm and supporting the outer circumference of the diaphragm, the conductive connecting portion having an elastic structure; wherein the actuator performs a bending vibration from a central portion of the actuator to a peripheral portion of the actuator such that the actuator is not in contact with the planar section at least while the actuator is being driven; and a drive voltage is applied to the diaphragm through the conductive connecting portion from the diaphragm support frame.
