Abstract
The invention discloses a piezoelectric vibration structure of an ink-jet printing head. The piezoelectric vibration structure comprises a vibration thin plate and a piezoelectric element, the vibration thin plate is composed of a material a and a material b, the piezoelectric element is composed of a top electrode, piezoelectric ceramics, a bottom electrode, a base plate and hinge support micro-areas, when the top electrode and the bottom electrode are electrified at the same time, the piezoelectric ceramics deforms, then the vibration thin plate deforms, ink is squeezed, and then the ink issprayed out. Compared with the prior art, the piezoelectric vibration structure has the following advantages that 1, a driving structure of the piezoelectric ink-jet printing head is simple in preparation process, and the repeatability is good; 2, the piezoelectric vibration structure has high vibration amplitude and frequency and long service life; and 3, the piezoelectric vibration structure canbe made of multi-layer materials such as metal, silicide, polymers, inorganic matter, organic matter or semiconductors, and the preparation cost is low.
