Description

Technical Field

[0001] This application relates to the technical field of formaldehyde pollution purification devices, and particularly to a formaldehyde pollution purification device. Background Art

[0002] Formaldehyde has been determined by the World Health Organization as a carcinogenic and teratogenic substance, is a recognized allergen, and is also one of the potential strong mutagens. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, pregnancy syndrome, leukemia and other diseases, and can also cause neonatal chromosomal abnormalities and memory and intelligence decline in teenagers. Among all exposed people, children and pregnant women are particularly sensitive to formaldehyde and are most harmed after absorption. People need to decorate new houses and offices. Since a large amount of artificial boards (such as plywood, blockboard, medium density fiberboard, particleboard, laminate flooring and engineered wood flooring, etc.) are used in decoration and furniture manufacturing, and a large amount of adhesives made with highly toxic formaldehyde are required for the production of artificial boards. Since the formaldehyde in the adhesives has a very long release period, generally up to 15 years, formaldehyde has become the main pollutant in indoor air.

[0003] In the existing formaldehyde pollution purification devices, the efficiency of removing formaldehyde is often not high, the use is rather cumbersome, and it is not convenient to replace the internal filter materials. Prolonged use may reduce the formaldehyde removal efficiency. Utility Model Content

[0006] By adopting the above technical solution, by setting an exhaust fan, during use, place the device housing in the room where formaldehyde needs to be removed. Then, the indoor air is inhaled into the interior of the suction pipe from air inlet 1 and air inlet 2 through the exhaust fan, and then discharged into the interior of the water tank through the other end of the suction pipe.
