Description

Technical Field

[0001] The utility model relates to the technical field of stripping liquid production, in particular to a stripping liquid injection head. Background Art

[0002] In the production process of stripping liquid, some solid substances will inevitably be produced, and these solid substances will enter the packaging barrel during filling, which will affect the quality of the stripping liquid. At present, in order to avoid this effect, the stripping liquid is first allowed to pass through the intermediate tank during liquid filling, and the impurities in the stripping liquid are filtered out through the intermediate tank. However, the intermediate tank currently used has a high cost, and these impurities are easily accumulated on the filter membrane of the intermediate tank during filtration. In order to avoid splashing during the liquid filling process, the intermediate tank is in a closed state, which increases the difficulty of cleaning the filter membrane. If the impurities accumulate excessively, the efficiency of liquid filling packaging will be affected. Utility Model Content
