A reagent nozzle mechanism for a nucleic acid synthesizer

Abstract

This utility model discloses a reagent nozzle mechanism for a nucleic acid synthesizer, comprising: a nozzle base, on which a liquid tube is installed; a connecting seat is provided below the nozzle base; the connecting seat has multiple through slots; a nozzle is disposed in each of the through slots; a connecting ring is fixedly welded to the top of the nozzle; four insertion posts are fixedly welded to the top wall of the connecting seat; each insertion post has a snap-fit ​​groove; and two snap-fit ​​mechanisms are provided on the nozzle base. In use, the connecting seat can be inserted into the insertion slots of the nozzle base via the insertion posts, allowing multiple nozzles to be connected to multiple insertion tubes respectively. An electric push rod can drive a moving rod to move, which in turn moves two snap-fit ​​blocks to snap into the corresponding snap-fit ​​grooves, thus securing the insertion posts. This facilitates the assembly and disassembly of the connecting seat, making it easy to remove multiple nozzles from the connecting seat for disinfection and cleaning.
