Description

Technical Field

[0002] Printing inkjet nozzle is a key component used in digital inkjet printing of textiles. It is responsible for spraying ink directly onto fabrics to generate high-resolution images and complex pattern effects. This nozzle usually adopts micro-piezoelectric technology to accurately control the spraying of ink to achieve fine printing patterns.

[0003] In the prior art, printing inkjet nozzles are frequently opened and closed during operation and have a certain service life. They need to be completely replaced after 300 days of normal operation. The rubber pads will become fatigued, so the entire nozzle needs to be replaced. In addition, the nozzles need to be replaced when they are blocked and cannot be sprayed, or when they cannot be cleaned due to excessive impurities. In the prior art, printing inkjet nozzles use electromagnetic type. When the printing inkjet nozzles are installed in the corresponding positions, the corresponding wires need to be electrically connected. When the snap-fit ​​area is narrow, it is not conducive to the installation of the printing inkjet nozzles.
