Tower-shaped air purification device

Abstract

The invention discloses a tower-shaped air purification device. An air discharging hole is formed in the top end face of a shell, and an air feeding hole opposite to and communicating with the air discharging hole is formed in the bottom of the shell; an ozone ultraviolet lamp and an ozone reduction ultraviolet lamp are vertically mounted on the top end face of the shell, and the surfaces of the ozone ultraviolet lamp and the ozone reduction ultraviolet lamp are coated with photocatalyst nanometer titania layers; a control device is mounted in the shell to control working states of the ozone ultraviolet lamp and the ozone reduction ultraviolet lamp; a supporting frame is erected on the shell in a tower mode, and an ultraviolet protective cover encloses the periphery of the supporting framein a tower mode and is provided with an airflow hole; a light blocking part blocking ultraviolet ray perpendicular emitting is arranged at the hole edge of the airflow hole; a fan is mounted in the shell, an air inlet and the air feeding hole are formed correspondingly, and an air outlet and the air discharging hole are formed correspondingly; and an activated carbon layer is mounted in the shelland located above the air outlet of the fan. The airflow hole of a light closing structure is formed in the ultraviolet protective cover of the air purification device, and ultraviolet light is not perpendicularly emitted to harm human bodies while it is ensured that air flowing through the interior of an air purifier freely exits and enters.

Description

technical field [0001] The invention relates to a tower-shaped air purification device. Background technique [0002] In the home environment, particleboard, MDF, plywood and other wood-based panels are generally used, but these panels contain a large amount of formaldehyde, which will pollute the indoor air and cause great harm to human health. [0003] Existing air purifiers are generally large in size, occupying a lot of household area, and are not easy to store or move. Moreover, in the prior art, disinfection and air purification of indoor space with direct ultraviolet irradiation and ozone disinfection will bring certain harm: for example, the direct ultraviolet irradiation sterilization method is only effective for that part of the outer surface facing the light source, However, it does not have a sterilizing effect on the back-to-light or sheltered places, and ozone will cause secondary pollution to the indoor space. [0004] Therefore, there is an urgent need for ...
