Abstract

The utility model discloses a filtering device for an air purifier, which comprises a cylindrical filter cylinder and an air filtering unit, wherein the air filtering unit is arranged on the filter cylinder and sequentially comprises an HEPA (high efficiency particulate air) particulate filter screen layer, an activated carbon filter layer and a nano silver filter layer from outside to inside. When the filtering device works, air entering the filtering device sequentially passes through the HEPA particulate filter screen layer, the activated carbon filter layer and the nano silver filter layer, so that the multi-layer filtering of air can be realized, a better filtering effect can be achieved, and harmful gas, bacteria and smells in air can be effectively purified. The filtering device disclosed by the utility model is simple in structure and easy to use.

Description

A kind of filter of air purifier

Technical field

The utility model relates to the air filtration technology, is specifically related to a kind of filter of air purifier.

Background technology

Air purifier is the small household appliances product that purifies the air of a room, and mainly solves because the air pollution problem inside rooms that finishing or other reasons cause.Air purifier mostly mainly is made of casing, filter, Duct design, motor, power supply, LCDs etc. in the market, and filter has determined the purification efficiency of air purifier.

The filter of existing air purifier only carries out a two-layer filtration to air, and the filter core burden is larger, causes filter effect not good, has shortened the service life of air purifier.

The utility model content

The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes a kind of filter of air purifier, and it has better filter effect.

In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:

A kind of filter of air purifier comprises that a cylindrical shape filtration barrel body, is installed in the air filter unit of described filtration barrel body, and described air filter unit ecto-entad comprises HEPA particulate filter mesh layer, activated carbon filter layer, nano silver filtering layer successively.

Preferably, described HEPA particulate filter mesh layer is wrinkle shape.

Than prior art, the beneficial effects of the utility model are: air filter unit of the present utility model comprises HEPA particulate filter mesh layer, activated carbon filter layer and nano silver filtering layer, can realize the multiple filtration of air, reach better filter effect, and the utility model result is simple, easy to use.

Description of drawings

Fig. 1 is the cutaway view of the filter of a kind of air purifier of the utility model.

The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further, so that clearerly understand the utility model technological thought required for protection.

As shown in Figure 1, be the structural representation of the filter of a kind of air purifier of the utility model, comprise a cylindrical shape filtration barrel body 10 and be installed in the air filter unit 2 of described cylindrical shell 10 inside, be provided with the gas channel that flows for air-flow in the filtration barrel body 10.

Air filter unit 2 ecto-entads comprise HEPA particulate filter mesh layer 21, activated carbon filter layer 22, nano silver filtering layer 23 successively.During work, air enters into air filter unit from the air inlet of filtration barrel body 10, behind the three layer filtration by HEPA particulate filter mesh layer 21, activated carbon filter layer 22, nano silver filtering layer 23, finishes filtration.

HEPA particulate filter mesh layer 21 is as the first filter course, and the effect of its filtration of particulate matters is very obvious.HEPA is interwoven by very tiny organic fiber, and stronger to the capturing ability of particulate, the aperture is small, and adsorption capacity is large, and purification efficiency is high, and possesses water imbibition, is 99.97% for 0.3 micron particle purifying rate.

Activated carbon filter layer 22 has abundant micropore, and very strong adsorption capacity is arranged, and can fully contact with gas (impurity), effectively adsorbs the pollutants such as chlorine residue that prime can't remove in filtering and small organic molecule.

Nano silver filtering layer 23 adopts particle diameter to accomplish that nano level argent simple substance as filtering material, can effectively play the effect of restraining and sterilizing bacteria, effectively purifies air.

In the utility model, HEPA particulate filter mesh layer 21 is wrinkle shape, can increase thus the contact area of HEPA particulate filter mesh layer 21 and air, thereby improves the efficient of filter.

During work, enter into the air of filter successively by HEPA particulate filter mesh layer, activated carbon filter layer, nano silver filtering layer, can reach better filter effect, airborne pernicious gas, bacterium and smell can both effectively be purified; And the utility model result is simple, easy to use.

For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.

Claims

1. the filter of an air purifier, comprise that a cylindrical shape filtration barrel body, is installed in the air filter unit of described filtration barrel body inside, is characterized in that: described air filter unit ecto-entad comprises HEPA particulate filter mesh layer, activated carbon filter layer, nano silver filtering layer successively.

2. the filter of a kind of air purifier as claimed in claim 1, it is characterized in that: described HEPA particulate filter mesh layer is wrinkle shape.
