A table with formaldehyde adsorption function

Abstract

The invention provides a table with a formaldehyde adsorption function. The table comprises a table body and a formaldehyde adsorption mechanism accommodated in the table body. The formaldehyde adsorption mechanism comprises a fixed seat, an adsorption barrel, a flexible waterproof shielding belt, an adsorption barrel driving piece and a first controller. The adsorption barrel is rotatably arranged on the fixed seat and internally provided with a plurality of adsorption cavities. Activated carbon is accommodated in the adsorption cavities. A plurality of sets of adsorption holes are formed inthe circumferential wall of the adsorption barrel. Each set of adsorption holes communicates with the corresponding adsorption cavity. The flexible waterproof shielding belt is connected with the fixed seat and arranged outside the circumferential wall of the adsorption barrel in a sleeving mode so as to seal the adsorption holes in the adsorption barrel. A communicating space is formed between the two opposite ends of the flexible waterproof shielding belt so as to enable one or more adsorption cavities to communicate with the outside world through the corresponding adsorption holes. The adsorption barrel driving piece is arranged on the fixed seat and connected with the adsorption barrel. The first controller is connected with the adsorption barrel driving piece. The table has the formaldehyde adsorption function.

Description

technical field [0001] The invention relates to a table, in particular to a table with formaldehyde adsorption function. Background technique [0002] Formaldehyde is a colorless gas with a strong pungent smell. A large amount of formaldehyde will be released during interior decoration, and long-term exposure of the human body can easily cause various diseases. People usually use the high specific surface area of ​​activated carbon to adsorb formaldehyde in the air, so as to achieve the purpose of purifying the air. In the prior art, people usually place activated carbon in a cloth bag to make a carbon bag or make an activated carbon filter screen and place it in an air cleaner for use. When using the charcoal bag, just place the charcoal bag in the air, which is convenient to use. However, activated carbon can absorb formaldehyde gas and water vapor in the air during use. After a period of use, the pore size inside the activated carbon is very large. Part of it is occupie...

Problems solved by technology

When using the charcoal bag, just place the charcoal bag in the air, which is convenient to use. However, activated carbon can absorb formaldehyde gas and water vapor in the air during use. After a period of use, the pore size inside the activated carbon is very large. Part of it is occupied by water molecules. Therefore, every certain period of time is usually 15-30 days, it is necessary to take the activated carbon to the outdoor exposure to empty the moisture in the aperture. The use time is short and the drying is frequent.

In addition, the formaldehyde adsorbed on the activated carbon is easily released after the adsorption is saturated, causing secondary pollution to the indoor air.

The use of air purifiers will occupy the usable area in the room, resulting in a reduction in the room for people to move around
