Abstract
A flow channel assembly (200) of a fluid micro-injection device has a fluid seat (210), a nozzle mounting plate (240), a nozzle (220), a nozzle platen (250) and a fluid supply joint (230). The nozzle (220) is connected to the fluid seat (210) by the nozzle mounting plate (240). The nozzle platen (250) is connected with the nozzle mounting plate (240) to secure the nozzle (220). The fluid supply joint (230) and the fluid seat (210) are connected to control the fluid flowing to the nozzle (220).
Claims12
A flow channel assembly of a fluid micro-injection device, comprising:
- a fluid seat defining a fluid chamber and a flow channel in communication with the fluid chamber therein;
- a nozzle mounting plate disposed under the fluid seat and provided with a through hole communicating with the fluid chamber;
- a nozzle disposed on the nozzle mounting plate and in communication with the through hole, a movable element of the fluid micro-injection device movably passing through the fluid chamber and the through hole to open or close the nozzle;
- a nozzle platen disposed entirely under the nozzle mounting plate and connected with the nozzle mounting plate to fix the nozzle;
- and
- a fluid supply joint communicating with the flow channel to provide fluid to the nozzle through the flow channel and the fluid chamber.
