An ink inlet channel is arranged in the middle of the base layer, and a pressure cavity is arranged in the cavity wall layer. The jet hole layer is provided with jet holes, the base layer is provided with a cavity wall layer and a jet hole layer in turn, the pressure chamber is communicated with the ink inlet channel and the jet hole respectively, and the cross section of the ink inlet channel is curved, which includes A base rectangular portion, a base extension portion a and a base extension portion b, a plurality of base extension portions a are respectively provided on both sides of the base rectangular portion in the width direction, and a base extension portion b is respectively provided at both ends of the base rectangular portion in the length direction; The invention has better printing quality, higher printing precision, timely ink supply, can completely fill the flow channel, and improve the inkjet quality.

Description

technical field [0001] The invention discloses a liquid jet flow channel, which belongs to the technical field of MEMS technology. Background technique [0002] The main element of the print head of an ink jet printer is a nozzle plate, which includes an ink supply channel, an ejection chamber and an ejection port for ejecting ink from the print head. Due to the widespread use of inkjet printers, in order to improve inkjet efficiency and reduce manufacturing costs, the nozzle plate has undergone significant design changes. In an attempt to accommodate high-speed printing and the high definition of the printed image, the design of the nozzle plate has also changed. While improvements in printhead design have enabled printheads to achieve higher resolution at higher print speeds, such improvements have presented new problems relative to the cost of manufacturing the nozzle plate due to the complexity of the design. The degree has increased so that, for the design of more com...
