AI Technical Summary

Technical Problem

Existing activated carbon filters, due to their non-foldable or non-separable monolithic structure, occupy a large space during transportation and storage, increasing transportation costs, and their poor sealing makes them prone to leakage, affecting the filtration effect.

Method used

A foldable activated carbon filter is designed, with a hinged housing structure that allows folding. The housing connection is equipped with a sealing strip and a compression spring to ensure airtightness and enhance the sealing performance after closure.

Benefits of technology

It saves space during transportation and storage, improves sealing, prevents gas leakage, and enhances filtration efficiency.
