Description

Composite air filter screen

Technical Field

The utility model belongs to the technical field of filter element nets, and particularly relates to a composite air filter net.

Background

Air purifier mainly is applied to and purifies a large amount of tiny granules of suspension in the air, wide application is in the environment and the home environment that produce the dust, and the filter core then is important component part among the air purifier, adsorption to tiny granule has a lot of effects, current air purifier's filter core net has two kinds of types usually, one kind is the filter core net that accords with by two-layer filter screen, another kind is by two-layer filter screen and compound adsorption material layer between two-layer filter screen constitutes, but these two kinds of filter core net are relatively poor at waterproof performance, get into the air filter effect variation that makes the filter core net when filter core net easily when the water, or even become invalid, based on this, it can waterproof air filter screen to be necessary to develop one kind.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a composite air filter screen to solve the above problems.

This utility model adopts for achieving the above purpose:

a composite air filter screen comprises a filter screen frame and a filter screen body, wherein the filter screen body consists of a first filter paper layer, a second filter paper layer, an active carbon filling layer, a first resin film layer and a second resin film layer, an annular groove is formed in the middle of the inner side wall of the filter screen frame, the filter screen body is embedded in the annular groove, the filter screen body is bonded with the annular groove by using an adhesive, the activated carbon filling layer is filled between the first resin film layer and the second resin film layer, the edges of the first resin film layer and the second resin film layer are connected into a whole through laser edge sealing, the first filter paper layer is connected on the outer side wall of the first resin film layer in a covering manner, the second filter paper layer is connected to the outer side wall of the second resin film layer in a covering mode, and the edges of the first filter paper layer, the second filter paper layer, the first resin film layer and the second resin film layer are connected into a whole through laser edge sealing.

It is further explained that the symmetrical central axial plane of the filter screen frame is coincident with the symmetrical central axial plane of the filter screen body.

Further, the first filter paper layer and the second filter paper layer are HEPA filter screens made of nylon resin materials.

Further, the first resin film layer and the second resin film layer are both polyethylene microporous filtering films, and the pore diameter of the polyethylene microporous filtering films is gradually increased from inside to outside.

Compared with the prior art, the utility model has the beneficial effects that:

through setting up first filter paper layer, second filter paper layer, active carbon filling layer, first resin rete, the complex of second resin rete as an organic whole, use in the actual time, the water that can prevent water filter screen body both sides accumulation in the setting of first resin rete, second resin rete soaks to the active carbon filling layer, only enables the air and enters into to the active carbon filling layer through the micropore on first resin rete, the second resin rete, has prolonged the life of whole filter screen.
