AI Technical Summary

Technical Problem

The existing window structure cannot effectively block the intrusion of external pollutants when the window is open for ventilation, and the cleaning of window screens is cumbersome and can easily cause secondary pollution.

Method used

Design a multi-layer composite air purification window structure, including dust removal and purification structures, and use a fan and non-woven fabric roller shutter to achieve air purification and convenient cleaning. It includes a dust collection box, a purification box, a non-woven fabric layer and multiple layers of filter materials, a fan control panel, etc.

Benefits of technology

It enables the purification of indoor air and the expulsion of polluted air when the glass windows are closed, while also facilitating the cleaning of window screens, reducing secondary pollution, and improving air purification effectiveness and aesthetics.

Abstract

A multi-layered composite air-purifying window structure includes a window frame comprising a top frame, a bottom frame, side frames, and a middle frame. The internal spaces of the top, bottom, and middle frames are interconnected, while the internal spaces of the two side frames are independently set. A first dust-removing air inlet is provided on the middle frame, and a dust-removing air outlet is provided on the bottom frame. A dust-removing structure, including a dust collection box and a first fan, is installed within the middle frame. A second dust-removing air inlet is provided on the top frame, which also features a non-woven fabric roller blind. Several purification air inlets and outlets are provided on the side frames, and a purification structure, including a purification box and a second fan, is installed within the side frames. This solution solves the problems of existing technologies where opening windows for ventilation fails to prevent the intrusion of external pollutants, and where cleaning screens is cumbersome and prone to secondary pollution.
