Problems solved by technology

Ordinary dust-proof screens either increase the mesh number of the screen from the physical structure of the screen, or paste a layer of adsorbent material to improve the filtration efficiency of particulate matter, but the filtration efficiency of fine particles is not good. , cannot effectively solve the indoor PM2.5 concentration problem in outdoor haze weather
The charged amount of negative ions released by negative ion powder is limited. If it is used as an anti-smog barrier and directly coated on ordinary window screens, its weak electric field force is difficult to completely capture the haze particles passing through the window screens. It is also difficult for the holes to block large particles in the air, which cannot achieve the effect of preventing haze

Embodiment 1

[0027] like Figures 1 to 3 As shown, a screen window with the effect of purifying air is provided in this embodiment, comprising a window frame 1 and a window screen 2, the window screen 2 includes an inner net 21 and an outer net 22, the outer net 22 is installed on the side facing the outside of the building, and the inner net Net 21 is installed on the inner side of the building, and outer net 22 is a stainless steel wire mesh. Inner net 21 includes fiber membrane layer 211 and activated carbon layer 212, and activated carbon layer 212 is arranged between fiber membrane layer 211 and outer net 22.

[0028] The activated carbon material in the activated carbon layer 212 can be in the form of fibers. The fine carbon particles have a large surface area, are rich in micropores, and have strong adsorption capacity. full exposure to air. When the air containing impurities is adsorbed by the micropores, it plays a role in purification.

[0029] The fiber membrane layer 211 is m...

Embodiment 2

[0032] The structure of the screen window in the present embodiment is basically the same as that of the screen window in Example 1, the difference is that the activated carbon material in the activated carbon layer 212 in the present embodiment is in the form of a porous spherical shape, which also has abundant micropores, and is in contact with air. In the process of full contact, it can fully absorb the impurities in the air.

[0033] The fibrous membrane layer 211 in this embodiment is composed of two layers of non-woven fabric support layer and multi-layer porous membrane layer, and the material used for the porous membrane layer is nanoscale porous material, such as nanoscale porous activated carbon.

[0034] What the fibrous layer in the fibrous film layer 211 in the present embodiment selects is nano-scale polymer material, is the composition of PP, PA and PVA, and the number of overlapping layers of the nanofibrous layer in the present embodiment is 2000 layers, compar...

Embodiment 3

[0037] The structure of the screen window in this embodiment is basically the same as the screen window in Example 1, the difference is that the fiber film layer 211 in this embodiment is made up of two layers of non-woven fabric support layer and one layer of fiber layer, the above fiber layer used The material is a micron-level natural fiber material, which is a combination of silk and wool.

[0038] Other technical features in this embodiment are the same as those in Embodiment 1.

Abstract

The invention discloses a screen window with the function of purifying air, which comprises a window frame 1 and a window screen net. The window screen net includes an inner net and an outer net. On the one hand, the outer mesh is a stainless steel wire mesh, and the inner mesh includes a fiber membrane layer and an activated carbon layer, and the activated carbon layer is arranged between the fiber membrane layer and the outer mesh. As an improvement of the above solution, the window screen of the present invention also includes a ventilation fan located on the outer side of the outer net and a wind speed sensor located on the side of the inner net of the window screen. In addition to preventing mosquitoes, the screen window of the invention can also prevent large particles of dust and even PM2.5 particles, so as to achieve the purpose of purifying the air.

Description

technical field [0001] The invention relates to the technical field of screen windows, in particular to a screen window with the function of purifying air. Background technique [0002] High concentrations of PM2.5 pollution affect ambient air quality and health. PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 μm in the atmosphere, also known as particulate matter that can enter the lungs. Each person inhales an average of about 10,000 liters of air every day. The fine dust that enters the alveoli can be quickly absorbed, and directly enter the blood circulation and distribute to the whole body without detoxification by the liver; secondly, it will damage the ability of hemoglobin to transport oxygen and lose blood. For patients with anemia and circulatory disorders, serious consequences may occur. For example, it can aggravate respiratory diseases and even cause heart diseases such as congestive heart failure and coronary arteries. These part...
