Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a cylinder inner wall cleaning machine. Background Art

[0002] Fire extinguishers are one of the most common firefighting equipment currently available and are stored in public places or places where fires may occur.

[0003] Nowadays, the production of fire extinguishers mainly involves several steps, including cylinder molding, cylinder internal molding, and cylinder filling. The internal molding of the cylinder is mainly to improve the anti-corrosion effect of the fire extinguisher. Therefore, in order to ensure the effect of the internal molding, the inner wall of the cylinder needs to be cleaned (mainly by jet cleaning) after the cylinder is molded. However, the current cleaning structure has a single jet direction at the jet end after it is inserted into the cylinder, resulting in a poor cleaning effect.

[0004] In summary, improvements need to be made. Utility Model Content
