AI Technical Summary

Technical Problem

In existing air filtration devices, the primary filter is easily clogged by impurities during use, resulting in reduced air intake efficiency. Moreover, the cleaning process is cumbersome, increasing workload and maintenance frequency.

Method used

A multi-layer composite air filtration device for cleanrooms based on uniform airflow distribution was designed. The cleaning brush is driven to move back and forth by a drive mechanism. Combined with a limiting and locking mechanism, the primary filter can be cleaned conveniently. The impurities are automatically cleaned and collected by a transmission mechanism and a collection mechanism.

Benefits of technology

It simplifies the cleaning process of the pre-filter, reduces maintenance frequency, improves cleaning efficiency and the practicality of the device, and ensures the stability and cleanliness of air filtration.
