Liquid injection nozzle cleaning mechanism

The utility model relates to a cleaning mechanism for a liquid injection nozzle. The cleaning mechanism comprises a cleaning part, a fixing part and a spray valve, the cleaning part is of a hollow structure, and a cleaning cavity used for containing the liquid injection nozzle is formed in the cleaning part. The fixing part wraps the outer side face of the cleaning part. The spray valve is fixed to the fixing part, and the interior of the spray valve communicates with the cleaning cavity through a spray channel. The DMC solvent atomized by the spraying valve flows through the spraying channel through compressed air, enters the cleaning cavity and washes the liquid injection nozzle in the cleaning cavity, the sprayed DMC solvent has high impact force, residual electrolyte on the periphery of the liquid injection nozzle can be effectively removed, and in addition, the cleaning efficiency is improved. Free floating objects formed by the crystallized electrolyte under the action of the DMC solvent can be separate
