A bed with formaldehyde adsorption function

Abstract

The invention provides a bed having a formaldehyde adsorption function. The bed includes a bed body and a formaldehyde adsorption mechanism accommodated therein. The formaldehyde adsorption mechanismincludes a fixing base, an adsorption cylinder, a flexible waterproof shield band, an adsorption cylinder driving member and a first controller. The adsorption cylinder is rotatably installed on the fixing base; a plurality of adsorption cavities are formed in the adsorption cylinder at interval and are filled with active carbon. A plurality groups of adsorption holes are arranged on the circumferential wall of the adsorption cylinder, every group of the adsorption holes being communicated with a corresponding adsorption cavity. The flexible waterproof shield band is fixedly connected with thefixing base and sleeves the circumferential wall of the adsorption cylinder, thus sealing the adsorption holes. The two opposite ends of the flexible waterproof shield band are in detachably connection, wherein a communicating space is formed between the two opposite ends, so that at least one adsorption cavity is communicated with exterior through the corresponding adsorption holes. The adsorption cylinder driving member is arranged on the fixing base and is connected to the adsorption cylinder. The first controller is connected with the adsorption cylinder driving member. The bed has the formaldehyde adsorption function.

Description

technical field [0001] The invention relates to a bed, especially a bed 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 occupied by water...

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
