Bubble point air filter screens/doors

Abstract

The invention discloses a bubble point type air filtering screen window / door. The bubble point type air filtering screen window / door comprises a window / door frame; a single bubble point type air filtering screen or double bubble point type air filtering screens is arranged on the window / door frame; the bubble point type air filtering screen consists of a planar framework material layer, an efficient low-resistance air filtering material layer and a bubble point framework material layer which are compounded, and has a sandwich structure; the upper layer of the bubble point type air filtering screen is a planar framework material layer; the middle of the bubble point type air filtering screen is an efficient low-resistance air filtering material layer; and the lower layer of the bubble point type air filtering screen is a bubble point framework material layer. The bubble point type air filtering screen window / door is made of the bubble point type air filtering screen; the bubble point type air filtering screen is high in strength, high in stiffness, low in air resistance and high in air filtering efficiency, can efficiently intercept fine particulate matters such as PM2.5 (particulate matters 2.5), does not affect air circulation, has various functions of energy conservation, noise prevention, thermal insulation, purification and mosquito prevention, and can replace the traditional screen window or door; and after outdoor polluted air is filtered, clean air is guided into an indoor environment, and indoor air circulation is kept.

Description

technical field [0001] The invention relates to a screen window / door, in particular to a bubble point 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 s...

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
