Fluid microdispensing device and its flow path assembly

摘要

A flow path assembly 200 of a microfluid injection device, wherein the flow path assembly 200 includes a fluid base 210 , a nozzle 220 , and a fluid supply joint 230 , and the fluid base 210 communicates with each other inside the fluid base 210 . The fluid chamber 211 and the flow path 212 are partitioned, the nozzle 220 communicates with the fluid chamber 211, and the movable element of the fluid micro-jet device movably passes through the fluid chamber 211 to the nozzle ( 220 is opened and closed, and the fluid supply joint 230 communicates with the flow path 212 , thereby supplying a fluid to the nozzle 220 through the flow path 212 and the fluid chamber 211 .
