Abstract
The invention provides a device structure and an air purifier. The device structure comprises a gas-sensitive resistor, a heating wire and a catalysis material layer; the gas-sensitive resistor is connected with the heating wire in series, the heating wire is coated with the catalysis material layer, the resistance of the gas-sensitive resistor is increased with the reduction of concentration of the assigned gas, so that when the concentration of the assigned gas is reduced, the heating wire reduces the heating temperature of the catalysis material layer, and the catalytic reaction speed of the catalysis material layer to the assigned gas is slowed. The device structure controls the catalytic reaction speed according to the gas concentration of the assigned gas, removal of the assigned gas is guaranteed, consumption of the catalysis material layer is reduced, and the usage cost is saved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a device structure and an air purifier. Background technique [0002] The existence of harmful gas in indoor air will endanger human health. In order to solve this problem, the existing method is to install harmful gas removal materials or devices indoors. [0003] The currently used harmful gas removal material is mainly activated carbon. Activated carbon can remove harmful gas by adsorbing gas. However, due to the upper limit of the adsorption capacity of activated carbon, activated carbon cannot effectively and continuously reduce the concentration of indoor harmful gases. [0004] The currently used harmful gas removal device uses thermal catalytic technology to degrade harmful gases in the air by heating the catalytic material. Compared with activated carbon, it has a continuous ability to remove harmful gases. However, since the harmful gas removal device is always kept i...
