Mask type filtering device for window

Abstract

The invention relates to a mask type filtering device for a window. The device comprises a screen window layer and an additional layer, the peripheral edge of the screen window layer is connected witha window body, and the additional layer is movably connected with the window body or the screen window layer. The mask type filtering device is detachably fixed on the window body or the screen window layer; the additional layer is easy to disassemble and assemble, and convenient to replace, so that cleaning becomes convenient; the dustproof filtering effect is achieved through the additional layer; outdoor fresh air can enter a room through the at least two layers of screen windows, outdoor poisonous and harmful microorganisms and bacteria are blocked, and the good effect of preventing outdoor flying dust, microorganisms, poisonous and harmful gas and PM2.5 is achieved.

Description

technical field [0001] The invention relates to the technical field of window screen manufacturing, in particular to a mask-type filter device for windows. Background technique [0002] A screen window is a device installed on a window or an entrance door to prevent mosquitoes or small particles of dust from entering the room. Common screen windows are generally made of steel mesh, which has the characteristics of reliable and durable installation. The existing screen windows mainly include invisible screen windows and flat-opening screen windows. The flat-opening screen window is the most widely used. On the screen window frame, the screen window frame is hinged to the window frame during use, or is slidably arranged in the track of the window frame.

Problems solved by technology

[0003] However, the screens currently used usually only have the functions of preventing mosquitoes, ventilation, and light transmission, and the filtering effect on solid suspended particles such as dust in the air is average. Some smaller mosquitoes or dust particles can still pass through the steel mesh and enter the room. According to calculations, the dust entering the room from ordinary screens accounts for about 80% of the total amount of indoor dust every day. In order to keep it clean, people have to clean it at any time, and buy vacuum cleaners and other equipment, which increases expenses and is time-consuming and laborious.

[0004] In addition, due to the serious air pollution now, resulting in smog, not only affect the hygiene in the living room, but also easily lead to respiratory diseases

In many cases, people want to open the windows for ventilation, but due to the severe smog, after opening the windows, traditional screens cannot prevent the smog from invading the room. Once the windows are opened, the indoor air will also contain a large number of smog particles

In order to reduce indoor smog, many families will choose to use air purifiers. There are also anti-smog filter screens in the prior art, but the current anti-smog screens lack adjustable performance, and they are only a single anti-smog, which has many disadvantages. , for example, the windows have poor lighting, and once the screens are polluted, it is difficult to clean them. When the screens are removed, the entire window has to be closed again, making it impossible to ventilate.

Therefore, the existing filter screens not only have high manufacturing costs, but also reduce the ventilation and light transmission performance of the screens.
