Preferably, activated carbon filter layer is further included, the activated carbon filter layer is abutted with filter screen inner wall, the activated carbon Filter layer includes two-layer nonwoven, the active carbon particle being clipped among two-layer nonwoven.

Through the above technical solutions, activated carbon is granular amorphous carbon, it, can be effective with stronger adsorptivity Ground absorbs the dust in air, particulate etc..

Preferably, the material of the filter screen is polypropylene or glass fibre.

Through the above technical solutions, polypropylene is a kind of hemicrystalline thermoplastic, the filter screen being made from it can The debris such as the dust effectively crossed in air filtering are to purify air, and polypropylene has the property such as impact resistance, wear-resisting, acidproof, alkaline-resisting Can, the filter screen service life being made from it is higher.Glass fibre is a kind of excellent inorganic non-metallic material of personality, by its system Into filter screen can effectively purify suspended matter, particulate, virus and bacterium in air, and glass fibre have it is anti-it is rotten, The advantages that tensile strength is high, the filter screen service life being made from it are higher.

Preferably, it is filled with rose particle in the filter screen.

Through the above technical solutions, Rose Essentielle can be carried by the air that the air filtering core purifies so that air can It is more pure and fresh, and the comfort level of user can be lifted to a certain extent.

Preferably, catch net is arranged with outside the filter screen, is offered in the installation groove bottom wall for being inserted for catch net The slot entered.

Through the above technical solutions, including catch net protects filter screen, catch net stops foreign object to mistake to a certain extent The impact of strainer, adds the service life of strainer.

In conclusion the utility model having the beneficial effect that in contrast to the prior art：Filter screen folds waviness so that Under identical volume, the contact area increase of filter screen and air, then the air filtering core provides the filter area of bigger, filtering It is efficient.

Embodiment

The utility model is described in further detail below in conjunction with attached drawing.

This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but As long as all protected in the right of the utility model be subject to Patent Law.

As illustrated in fig. 1 and 2, a kind of air filtering core, shape are cylinder, its side wall includes activated carbon mistake successively from inside to outside Filtering layer 1, the filter screen 2 being set in outside activated carbon filter layer 1, the catch net 3 being set in outside filter screen 2, activated carbon filter layer 1, Lid 4 is provided with the both ends of filter screen 2 and catch net 3.

As shown in Figures 2 and 3, activated carbon filter layer 1 is annular shape, and activated carbon filter layer 1 includes two-layer nonwoven 11, is clipped in Active carbon particle 12 among two-layer nonwoven 11, activated carbon is granular amorphous carbon, it is with stronger adsorptivity, energy It is enough effectively to absorb the dust in air, particulate etc..

As shown in figure 4, filter screen 2 is circular and folding waviness, outside 2 inner wall of filter screen and activated carbon filter layer 1 Wall is bonded, and the material of filter screen 2 is polypropylene or glass fibre, and is filled with rose particle in filter screen 2, by this The air of air filtering core purification can carry Rose Essentielle so that air can be more pure and fresh, and can be lifted to a certain extent The comfort level of user.

Polypropylene is a kind of hemicrystalline thermoplastic, and the filter screen 2 being made from it can be crossed effectively in air filtering The debris such as dust are to purify air, and polypropylene has the performance such as impact resistance, wear-resisting, acidproof, alkaline-resisting, the filtering being made from it 2 service life of net is higher.
