And because the second filter body 2 is arranged between the first filter screen 11 and the second filter screen 12, the replacement time of the first filter body 1 or the second filter body 2 can be delayed, and the service life of the filter assembly can be prolonged. Therefore, the filter assembly provided by the embodiment of the utility model has the advantages of good filter effect, convenience in installation and disassembly and lower cost.

For example, the first screen 11 and the second screen 12 may filter solid contaminants and gaseous contaminants, respectively. As another example, both the first screen 11 and the second screen 12 may filter solid contaminants and gaseous contaminants. It is understood that the target pollutant may be formaldehyde, TVOC, bacterial, or viral pollutant, and the kind of specific decomposition and filtration of the target pollutant is not specifically limited in this application.

In some embodiments, as shown in fig. 2 and 3, the second filter body 2 includes a third filter screen 21, the third filter screen 21 having a catalytic layer for catalytically decomposing toxic organic compounds. It is understood that in embodiments of the present application, the target contaminant may be formaldehyde. The catalytic layer is a manganese catalytic layer, and can decompose formaldehyde, so that formaldehyde in the air can be purified.

Optionally, as shown in fig. 3, the second filter body 2 further includes a fourth filter 22, where the fourth filter 22 is disposed on a side of the third filter 21 adjacent to the second filter 12, the first filter 11, the third filter 21, the fourth filter 22 and the second filter 12 can filter air sequentially, and the fourth filter 22 can block the catalytic products on the third filter 21 from entering the second filter 12.

When the third filter 21 catalyzes the target pollutant in the air, the catalytic product on the third filter 21 may fall to the bottom of the accommodating chamber 14 or enter into the second filter 12. According to the filter assembly provided by the embodiment of the utility model, the third filter screen 21 is arranged to avoid the risk of falling of catalytic products on the third filter screen 21, and on the other hand, the third filter screen 21 can also filter pollutants such as dust or peculiar smell, so that the integral filtering effect of the filter assembly is improved.

In some embodiments, the first screen 11, the second screen 12, the third screen 21, and the fourth screen 22 may be manufactured by crimping, glue injection, structural design, or mold production. The filter material can be chemical fiber filter material, glass fiber, PTFE, electrostatic cotton, electrostatic dust collector, active carbon, adsorptive material, photocatalyst material, antibacterial and antiviral material, antiallergic raw material, etc.

Alternatively, as shown in fig. 2 and 3, the first filter screen 11 has a particulate matter filter layer, and the second filter screen 12 has an activated carbon adsorption layer. It can be understood that the particulate matter filtering layer of the first filter screen 11 can filter particulate solid pollutants, the third filter screen 21 can catalytically decompose toxic organic compounds, and the activated carbon adsorption layer of the second filter screen 12 can adsorb and filter peculiar smell or residual solid pollutants, so that the filtering assembly of the embodiment of the utility model can realize better filtering effect of the filtering assembly by classifying the pollutants and complementing the filter screens at different levels.

In some embodiments, as shown in fig. 1 to 4, the first filtering body 1 further includes a first frame 13, the first filter screen 11 and the second filter screen 12 are integrated on the first frame 13, and the first filter screen 11, the second filter screen 12 and the first frame 13 define a receiving cavity 14 together. Specifically, the first screen 11 and the second screen 12 are arranged in parallel and on both sides in the thickness direction of the first frame 13, respectively, and the enclosed accommodation chamber 14 is a rectangular chamber. For example, the first frame 13 may be a paper frame, a plastic frame, or a metal frame. The filter assembly of the embodiment of the utility model can protect the outer edges of the first filter screen 11 and the second filter screen 12 by integrating the first filter screen 11 and the second filter screen 12 on the first frame 13, is convenient for processing and manufacturing the first filter body 1, and has higher structural strength.

Optionally, as shown in fig. 1 to 4, the second filtering body 2 further includes a second frame 23, and the third screen 21 and the fourth screen 22 are integrated on the second frame 23. For example, the second frame 23 may be a paper frame, a plastic frame, or a metal frame. The filter assembly of the embodiment of the utility model can protect the outer edges of the third filter screen 21 and the fourth filter screen 22 by integrating the third filter screen 21 and the fourth filter screen 22 on the second frame 23, and the second filter body 2 has higher structural strength and is not easy to damage.

In some embodiments, as shown in fig. 2, the outer peripheral wall of the second filter body 2 is in close contact with the inner peripheral wall of the receiving chamber 14, so that the second filter body 2 is clamped within the receiving chamber 14. It will be appreciated that the second filter body 2 may be mounted in the receiving chamber 14 in a drawing manner, and that the second filter body 2 may be drawn directly out of the receiving chamber 14 when the second filter body 2 needs to be replaced. Since the outer peripheral wall of the second filter body 2 is tightly attached to the inner peripheral wall of the accommodating cavity 14, the problem that the second filter body 2 shakes relative to the first filter body 1 can be avoided after the second filter body 2 is mounted in the accommodating cavity 14, and the stability of the second filter body 2 after being mounted is improved.

Optionally, as shown in fig. 4, a notch 24 is provided on one side of the second filter body 2, and a protrusion (not shown) is provided in the accommodating chamber 14, and the notch 24 matches with the protrusion. For example, the notch 24 is located at a position of the second filter body 2 adjacent to the top corner of the bottom of the accommodating chamber 14. Accordingly, the location of the protrusion corresponds to the notch 24. It will be appreciated that the second filter body 2 has a front side and a back side, i.e. the third filter screen 21 needs to be located outside the fourth filter screen 22. Due to the notch 24, when the user installs the second filter body 2 reversely, other parts of the second filter body 2 are propped against the protruding part, so that the second filter body 2 cannot be pushed into and extend into the accommodating cavity 14 completely, thereby reminding the user of the installation error. Similarly, when the user correctly positions the front and back sides of the second filter body 2, the notch 24 corresponds to the protrusion, so that the second filter body 2 can be pushed into the accommodating cavity 14 entirely. The filter assembly of the embodiment of the utility model can avoid the problem of reverse installation of the second filter body 2 by arranging the notch 24 and the convex part, thereby improving the convenience of the filter assembly installation.

On the other hand, since the first filter screen 11 and the second filter screen 12 can filter solid contaminants or gaseous contaminants, the second filter body 2 can filter target contaminants, thereby performing composite filtration on contaminants in the air and improving the air filtering effect. And because the second filter body 2 is arranged between the first filter screen 11 and the second filter screen 12, the replacement time of the first filter body 1 or the second filter body 2 can be delayed, and the service life of the filter assembly can be prolonged. Therefore, the filter assembly of the air purifier has good filter effect, convenient installation and disassembly and lower cost.
