Indoor air purification device

Abstract

The invention discloses an indoor air purification device. The device is characterized by comprising a box, an active carbon bag, box covers and a telescopic rod, the box is provided with an upper cavity and a lower cavity, the active carbon bag is placed in the cavities, a shaft hole is formed in the center of the left side face of the box and extends to the center of the right side face of the box so as to penetrate through the box transversely, the telescopic rod is placed in the shaft hole, and the two cavities of the box are covered with the two box covers. The box can turn over forwards and backwards around the telescopic rod, and decoration pollutants including formaldehyde can be adsorbed when the front side of the box faces the room; when the active carbon bag needs to be exposed to the sun, people only needs to turn over the box to make the front side of the box face the outside, and in this way, a backboard separates indoor space from outdoor space, so that secondary indoor pollution caused by formaldehyde diffusion when the active carbon bag is irradiated by the sun is avoided.

Description

technical field [0001] The invention relates to an air purification device, in particular to an indoor air purification device, and belongs to the technical field of air purification. Background technique [0002] Newly renovated or refurbished residences contain decoration pollutants such as formaldehyde. Activated carbon is a good material for adsorbing pollutants such as formaldehyde. Now most of the activated carbon on the market is made into bags of carbon bags and placed indoors. In order to let it absorb formaldehyde independently, in order to ensure the adsorption performance of activated carbon, it is necessary to take it outside to bask in the sun every few days. At present, for high-rise residential areas, the installation of windows and guardrails is not allowed to exceed the facade wall, resulting in activated carbon bags can only be dried on the balcony, mostly due to the problem of balcony area and drying bearing equipment, resulting in inconvenient drying, re...

AI Technical Summary

Problems solved by technology

At present, for high-rise residential areas, the installation of windows and guardrails is not allowed to exceed the facade wall, resulting in activated carbon bags can only be dried on the balcony, mostly due to the problem of balcony area and drying bearing equipment, resulting in inconvenient drying, repeated use of activated carbon bags The efficiency is low, and the effect of purifying indoor pollutants such as formaldehyde is poor
