Abstract

The invention provides a self-cleaning high-speed and high-efficiency inkjet piezoelectric spray head. The self-cleaning high-speed and high-efficiency inkjet piezoelectric spray head comprises a nozzle. An inkjet channel is arranged on the nozzle. The inkjet channel comprises a communicating section and a nozzle section. An ink outlet of the communicating section is connected with an ink inlet ofthe nozzle section. A multistage gradient micro-nano structure is arranged on the inner wall of the nozzle section. The multistage gradient micro-nano structure comprises a micron-level structure anda nano-level structure. The micron-level structure is arranged on the inner wall surface of the nozzle section. The nano-level structure is arranged on the micron-level structure. According to the self-cleaning high-speed and high-efficiency inkjet piezoelectric spray head, the inner wall surface of the inkjet channel has good hydrophobicity, so that ink does not generate flow resistance and viscosity in the extrusion process of the piezoelectric spray head, the self-cleaning function of the inner wall structure of the nozzle is realized, the inkjet performance of the piezoelectric spray headis improved, and the maintenance frequency and cost of the piezoelectric spray head are reduced.

Description

technical field [0001] The invention relates to a self-cleaning high-speed and high-efficiency ink-jet piezoelectric nozzle. Background technique [0002] The nozzle is the core component of the inkjet printer. The ink ejects liquid droplets with a certain speed to the printing medium through the nozzle. The internal structure of the traditional nozzle is an ordinary smooth surface, such as figure 1 , presents a statistically significant roughness, does not have a regular microstructure on the surface, and the inner wall of the nozzle has a high degree of hydrophilicity. The speed and precision with which ink is ejected is low. Moreover, when the viscosity of the ink at the nozzle part increases, it will cause flexible clogging, resulting in disconnection failures, which will affect the overall performance of the printer, and will waste ink during cleaning and increase costs. [0003] The above problems should be considered and solved in the design and production process o...
