Abstract
An inkjet head includes a main body, a film, a piezoelectric atomizer, a cover and a nozzle plate. The main body includes a cavity receiving a fluid with an opening connecting the cavity. The cover is fastened to a top end of the main body. The film is interposed between the cover and the main body. The nozzle plate includes a plurality of nozzles. The nozzle plate is disposed on a bottom end of the main body. The piezoelectric atomizer is interposed between the cover and the film. The piezoelectric atomizer introduces pressure variations in a static pressure to atomize the fluid.
