Because the sealing rings are arranged around the contact between the air channel of the cleaning head assembly and the battery injection port 21 for pressing and sealing, the cleaning head assembly can be ensured to be in a closed environment during working, and environmental pollution caused by electrolyte leakage is prevented.

Further, the above embodiment is suitable for cleaning the battery after the secondary liquid injection, the secondary liquid injection is to supplement the electrolyte after the primary liquid injection, after the secondary liquid injection is completed, the liquid injection port of the battery is completely closed, and at this time, the residual liquid removing device is connected with the liquid injection port of the battery, so that the electrolyte remained on the liquid injection port can be cleaned. However, in some special cases, it is necessary to clean the electrolyte injection port after the battery is injected once. The primary liquid injection is to inject electrolyte into the battery through the liquid injection cup, and after the primary liquid injection is completed, the liquid injection port is not closed, so that the liquid injection port needs to be closed after the secondary liquid injection is completed.
