Abstract

The invention provides a liquid jet manufacturing method, a liquid jet and a printing device. The liquid jet manufacturing method comprises forming a plurality pressure generating units at intervals on a first substrate; forming a plurality of pressure cavities, which correspond to the pressure generating units, and a plurality of common cavities communicated with the pressure cavities on the first surface of the substrate; forming transition layers on the pressure cavities through the bonding process, and forming a jet hole plate on the transition layers; forming jet holes communicated with the pressure cavities on the jet hole plate and the transition layers through the photoetching process. According to the liquid jet manufacturing method, the pressure cavities and the common cavity are formed on the first surface of the first substrate, so that when more pressure cavities of liquid jets are required, the pressure cavities can be formed independently on the first substrate without reducing the mechanical strength of the first substrate; during the manufacturing process, damage to the first substrate can be avoided, so that the yield rate of the liquid jets can be improved, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to printing technology, in particular to a method for manufacturing a liquid ejection head, a liquid ejection head and a printing device. Background technique [0002] The liquid nozzle of the printer changes the volume of the pressure chamber through the deformation of the piezoelectric element and the vibration plate, so that the ink in the pressure chamber is ejected from the nozzle hole. [0003] A conventional liquid spray head includes a substrate, a vibrating plate and a piezoelectric element arranged on the first surface of the substrate, and an orifice plate bonded on the second surface of the substrate (the surface opposite to the first surface). The existing manufacturing method of the liquid ejection head is: form a vibrating plate and a piezoelectric element on the first surface of the substrate, and etch a plurality of corresponding piezoelectric element positions on the substrate through an etching process on the se...
