AI Technical Summary
Existing cell factory sealing devices are cumbersome to use and increase the risk of cell fluid contamination, making it difficult to meet the operational needs of different stages.
Design a sealing device including a cover, a filter element, and connecting pipes. The device achieves sealing and ventilation of the cell factory through different installation methods of the cover. It uses a PTFE membrane as the filter element, combines a reinforcing plate to improve the strength of the filter element, and supports convenient replacement of the filter element.
It simplifies the operation process of cell factories, reduces the risk of external contamination, meets the usage needs at different stages, and improves the strength of filter elements and the ease of filter replacement.
