The device comprises a bottom plate, a first fixing plate is fixedly connected to the upper surface of the bottom plate, a shell is in threaded connection with the outer side wall of the first fixing plate, a first filtering net, a formaldehyde filtering net and an activated carbon plate are arranged in the shell, the formaldehyde filter screen is located above the first filter screen, the activated carbon plate is located above the formaldehyde filter screen, in the using process of the device, the shellis in threaded connection with the first fixing plate, so that the shell is convenient to disassemble, meanwhile, the first filter screen, the formaldehyde filter screen and the activated carbon plateare in sliding connection on the rod body. The first filter screen, the formaldehyde filter screen and the activated carbon plate are convenient to disassemble, replace or clean, the air purificationeffect of the device is guaranteed, formaldehyde is purified more thoroughly, air purification work is facilitated, operation is easy, and convenience is brought to users.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, in particular to an air purification filter device for removing formaldehyde. Background technique [0002] As we all know, the content of volatile organic compounds in ordinary decoration materials is generally relatively high, for example: paints, coatings, plywood, particle board, foam filling materials, plastic veneers, etc. all contain formaldehyde, benzene, toluene, ethanol, chloroform, etc. Effective removal of these volatile organic compounds in the decorated house will form "indoor pollution", which will have some impact on the health of the occupants. "Indoor pollution" means that the amount of air pollutants entering the room exceeds The self-purification ability of the indoor environment will cause the decline and deterioration of the indoor air quality, which will directly or indirectly have adverse effects on the body of the occupants. Air purifiers are also calle...

AI Technical Summary

Problems solved by technology

[0003] China's public authorized invention: CN209865594U discloses a formaldehyde-removing indoor air purifier, which includes a casing, a particle filter, an air intake pipe, a protective casing, and a fan. The bottom of the casing is equipped with mutually symmetrical fans. The multiple filtering functions of the air purifier have been realized. However, in the actual use process, the filter components such as the filter screen need to be cleaned regularly to avoid clogging of the filter screen to ensure the filtering effect of the filter screen. In the process of use, it is not conducive to the disassembly, cleaning or replacement of the filter screen and filter parts, which is not conducive to the purification of the air, and brings inconvenience to the users. Therefore, an air purification filter device for removing formaldehyde is proposed.
