DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The main body 4, the upper cover body 10 and the lower cover body 11 are all made of breathable material. The main body 4 has a plurality of partition walls 8. The plurality of partition walls 8 extend axially and are separated in a radial plane to form a plurality of accommodating holes 6. A plurality of filter particles 5 are arranged in each accommodating hole 6. The upper cover body 10 and the lower cover body 11 are respectively arranged on both ends of the main body 4.

[0030] It should be noted here that the upper cover 10 and the lower cover 11 are both fixedly connected to the main body 4 to prevent the filtered particles 5 from spilling out.

[0031] In a preferred embodiment, the filter particles 5 are AOP solid alkali particles, which can efficiently remove organic matter in the air, such as odor, volatile organic compounds, etc., as well as remove microbial pollutants such as bacteria and viruses.

[0032] It should be noted here that AOP solid alkali granular oil is purchased from Shenzhen Kangfeng Environmental Technology Development Co., Ltd. There are many nano-level pores on the surface of each particle of AOP solid alkali. When polluted air passes through the particles, it will produce a large number of hydroxyl free radicals. Hydroxyl free radicals have very strong oxidizing properties and can quickly oxidize pollutants in the air, such as formaldehyde and bacteria, and turn them into harmless carbon dioxide molecules and water molecules, thereby achieving the effect of cleaning the air.

[0033] In a preferred embodiment, the accommodating hole 6 is in a honeycomb shape.

[0034] It should be noted here that: a number of AOP solid alkali particles are arranged in each accommodating hole 6, and this honeycomb structure can be evenly filled with AOP solid alkali particles to achieve a better purification effect and increase the service life of the filter element 2.

After long-term use, when the AOP solid alkali particles become ineffective, only the filter element 2 needs to be replaced to ensure that the air purifier can effectively purify the air and maintain the efficient operation of the air purifier.

[0036] It should be noted here that the filter element 2, the inner layer component 1 and the outer layer component 3 are arranged in sequence from the inside to the outside, so that the gas is filtered layer by layer, ensuring that harmful gases and odors in the air are filtered out more thoroughly, protecting human health and safety, and can effectively remove bacteria, viruses and other microbial pollutants in the air.

[0037] In a preferred embodiment, the filter element 2 and the inner layer component 1 are interference fit.

[0038] It should be noted here that: when the filter element 2 is not installed in the inner layer component 1, the outer diameter of the filter element 2 is slightly larger than the inner diameter of the inner layer component 1, so that when the filter element 2 is installed in the inner layer component 1, the outer wall of the filter element 2 is elastically deformed and abuts against the inner wall of the inner layer component 1 to prevent the filter element 2 from moving in the axial direction.
