Folding Air Filter Screens/Doors

Abstract

The invention discloses a folding type air filtering screen window / screen door which comprises a window door frame. A singly opened or oppositely opened foldable honeycomb type air filtering screen is installed on the window door frame. The honeycomb type air filtering screen comprises two layers of filtering surfaces, the joint of the two layers of filtering surfaces is provided with a plurality of hexagonal honeycomb connecting channels, and the filtering surfaces are formed by compounding an outer plane framework material layer and an inner efficient low-resistance air filtering material layer; or the filtering surfaces are formed by compounding an outer plane framework material layer, a middle efficient low-resistance air filtering material layer and an inner plane framework material layer. The folding type air filtering screen window / screen door is made by adopting the honeycomb type air filtering screen, can efficiently intercept fine particles such as PM2.5 without affecting air circulation, have multiple functions such as energy saving, noise prevention, heat insulation, purification and mosquito prevention, can replace a conventional screen window / screen door, filter outdoor polluted air and then introduce the air indoors, and maintain indoor air circulation.

Description

technical field [0001] The invention relates to a screen window / door, in particular to a folding air filter screen window / door. Background technique [0002] With our rapid urbanization process, industrial and economic development, air pollution is becoming more and more serious (especially fine particle pollution such as PM2.5), especially since 2013, the smog weather mainly caused by PM2.5 pollution Invading most of the eastern part of China, important cities such as Beijing and Shanghai suffered greatly, and people's health was seriously affected. Severe smoggy weather outside makes it impossible for ordinary people to open windows for ventilation, while indoor air that is not circulated makes people uncomfortable and has a long-term serious impact on people's health. [0003] Existing screen windows and screen doors are divided into cotton gauze, polyester cloth, etc. according to their materials, and usually have fine meshes, which can block the entry of insects such a...

AI Technical Summary

Problems solved by technology

Conventional yarn does not affect air circulation, but due to its large mesh size, it cannot isolate fine particles such as PM2.5. In today's deteriorating environment, the haze weather can only be protected by closing doors and windows, and cannot be opened for replacement. Air, if you want to make yarn from similar mask materials that can isolate PM2.5 and other fine particles, the air resistance is too large to achieve the ventilation effect
