AI Technical Summary

Problems solved by technology

The filter bottle cover adopts the design of the tower structure, and the first opening and the second opening are arranged on different layers of the tower structure, and then through the cooperation with the valve body of the tower structure, the valve body and the filter bottle cover are realized. The separation of water and effluent, the structure of this filter device is more complicated
