Abstract
A bi-direction pumping droplet mist ejection apparatus includes a casing which has two sides each has an inlet and a plurality of nozzle orifices, and a piezoelectric plate located in the casing and clamped and anchored by a clamping pad on one end thereof. The casing has a reservoir and an ejection chamber located on each of two sides of the piezoelectric plate. The reservoir and the ejection chamber are interposed by flow guiding slant surfaces and buffer edges to enable the piezoelectric plate and the nozzle orifices to form a gap therebetween to cerate nozzle and dispersion effects so that after the piezoelectric plate is activated fluid may be ejected evenly through the nozzle orifices on two sides to generate even fuel ejection and a desired atomization effect in a bi-direction fashion.
