Technical Field

[0001] The utility model relates to the field of air purification, in particular to a formaldehyde removal device. Background Art

[0002] Formaldehyde is a colorless gas with a strong irritating odor. Long-term inhalation of formaldehyde is extremely harmful to the human body. The formaldehyde in indoor air mainly comes from the artificial wood boards used in decoration materials and new modular furniture, such as plywood, core board, medium-density fiberboard, and particle board (chipboard). When exposed to heat and deliquesce, the formaldehyde in the adhesive is released. The insulation material used for heat and cold protection in houses, the foam, can also release formaldehyde after aging under the action of light and heat. Paints, chemical fiber carpets, cosmetics, floor glue and other products that use formaldehyde as a preservative can also slowly release formaldehyde.

[0003] Chinese patent announcement number CN214389572U discloses a multi-purpose formaldehyde removal and deodorization purification device. When in use, the bottom of the outer container is squeezed to force the fragile inner container to rupture, so that the second substance flows into the outer container and reacts with the first substance to slowly release chlorine dioxide gas. When in use, the easy-pull bottle cap on the top of the outer container is not torn off. Low-concentration chlorine dioxide can be released into the space through the air-permeable outer container, which can be used for deodorizing a small space. When in use, the easy-pull bottle cap on the top of the outer container is torn off, and high-concentration chlorine dioxide can be directly released into the space, which can be used to remove formaldehyde indoors and in cars.
