[0002] Piezoelectric jet valves are typically suitable for jetting small volumes of viscous fluids, and are applicable to various electronic industry circuit boards using UV-curable adhesives, epoxy resins, conductive silver pastes, thermally conductive greases, fluxes, and hot-melt structural adhesives. They can handle adhesive viscosities ranging from tens of centipascals to tens of thousands of centipascals. Furthermore, due to their high precision, high efficiency, and wide applicability, their market share is gradually expanding.

[0003] With the widespread application of piezoelectric injection valves, the flow channel module, as an important component of the valve body, has been subject to various user demands, including but not limited to ease of cleaning, ease of installation, and size limitations. Currently, cleaning and maintenance of the flow channel module requires first removing the entire piezoelectric valve from the machine, then disassembling the flow channel for cleaning. This necessitates recalibrating the dispensing accuracy after the piezoelectric valve maintenance is complete, wasting considerable time. Consequently, many users neglect maintenance and cleaning, affecting the valve body's performance and lifespan.

[0004] To address this issue, this utility model provides a piezoelectric jet valve body flow channel module, which solves the problem that existing piezoelectric valve flow channel modules are not suitable for quick cleaning and maintenance, thus affecting the performance and lifespan of the piezoelectric valve. This optimizes the convenience of cleaning the flow channel module while ensuring that the performance and lifespan of the valve body are not affected by cleaning. Utility Model Content
