Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a printing machine, and more particularly to an ink jet splitting micro nozzle. [Prior Art] U.S. Patent No. 7,219,982 discloses a conventional inkjet device micro-nozzle comprising an ink tank, a fixing plate, a solenoid and a piston, the fixing plate being coupled to the ink robbing side, the snail The wire tube is fixed to the fixing plate, the piston is coupled to one side of the fixing plate, and the solenoid is interposed between the fixing plate and the piston. When the solenoid is energized, a magnetic force is generated, and the piston is magnetically attracted to the solenoid to be squeezed into the interior of the ink tank, causing ink to be ejected. However, the structure of the micro-nozzle of the spray device 4 causes an increase in manufacturing cost, and the fine particle distribution around the particles ejected by the micro-nozzle of the ink-jet device is caused to cause poor printing quality. Referring to Fig. 1, it is another conventional ink jet device micro-injector 1 which comprises an ink containing chamber 91, a recording sheet 92, an ink tube 93, and a piezoelectric ring 94. The bottom of the ink chamber 91 has an opening 911 at the bottom; the nickel piece 92 covers the opening 911 of the valley ink to 91, and the day is released 921; the ink tube 93 is worn (four) 4 and the nickel piece 92 forms an ink. The hole 3 passes through the top portion 91 of the valley ink chamber and extends into the fog palace 91; the piezoelectric ring piece 94 fits and extends to the conventional ink jet device micro nozzles ^, 2 and surrounds the ink discharge. Hole 921. The piezoelectric ring piece 94 is deformed, and when t=2, the piezoelectric effect is used to drive the depression, and the nickel piece 9 garment 94 is driven into the ink containing chamber 91. At this time, since the nickel piece 92 is pressed, the chamber is pressed. A depression is formed in 91. Each of the inks has a space of 91, so that the ink discharge holes 921 of the ink 201024098 92 form microdroplets. Then, the piezoelectric ring piece 94' deforms the piezoelectric ring piece to form a protrusion, drives the _92_ raw, and detaches the micro-droplet on the hole 921 to complete the ink-jet process. . However, the conventional ink jet device micro-nozzle still has the following disadvantages, for example, the piezoelectric ring piece 94 has a limited amount of deformation, and the deformation amount can only be compressed and squeezed.

The first step is the same as the inkjet program described above when applied to a low-viscosity ink, and the deformation controller 7 drives the first deformation ring piece 5 and the second deformation ring piece 6 to be concavely deformed toward the inner space by a piezoelectric effect. As shown in FIG. 7 , the second step is: the first deformation ring piece 5 is kept recessed toward the inner space, that is, the first elastic piece 2 is not reset, and the second deformation ring piece 6 is directed to the ink. A protrusion is formed outside the chamber to drive the second elastic sheet 3 to also protrude toward the outside of the ink containing chamber i to separate the micro droplets from the ink outlet hole 33, as shown in FIG. Thus, when the first elastic sheet 3 is formed into a convex shape, the instantaneous elastic force is not caused by the resetting of the first elastic sheet 2, and the amount of actuation force generated by the second elastic sheet 3 is insufficient to be used. In the high return of the ink. In summary, the present invention particularly provides the first deformation ring piece 5 and the second deformation ring piece 6 on the inner side _ opposite sides, and drives the first deformation ring piece 5 and the second through the deformation controller 7 The deformation ring piece 6 drives the first elastic piece and the second elastic piece 3 to generate deformations, and the deformation controller 7 can control the deformation of the two deformation ring pieces W^曰1 according to different timing control of the inks with different viscosity. _Poor' increases the success rate of droplet ejection from the micro-drops attached to the ink-dissipation port to improve ink-jet accuracy. As mentioned earlier, this. The first green sheet 2 and the first-elastic & sheet 3 cover the reduced diameter step portion 201024098 11 of the ink containing chamber i to adjust the capacity of the ink containing chamber 1 and The first elastic piece 2 and the second elastic piece 3 are respectively attached to the first elastic piece 2 and the second elastic piece 3 to control deformation of the first elastic piece 2 and the second elastic piece 3 to be extruded. Ink or ink. In addition, by controlling the flow of the ink jet, the ink jet device micro-nozzle of the present invention can be applied to low-viscosity and high-viscosity inks to improve the usability.
