Abstract

The invention provides an air conditioner comprising an air conditioner main body, the air conditioner main body comprises a filter net, the filter net is plated with TiO2 coating layer, the TiO2 coating layer is doped with NxOy and transition metal oxide, a light source is provided in the air conditioner main body; the NxOy and the transition metal oxide can cooperate to catalyze the TiO2, so that the nano TiO2 can catalyze the required light area from the ultraviolet light area to the visual light area, thereby improving the photochemical catalysis activity of the nano TiO2, increasing the selection range of the light source, improving the deodorization effect, meanwhile, the selectivity of the light source is much more and the price is low.

Description

technical field [0001] The invention relates to the field of air purification devices, in particular to an air conditioner capable of purifying air. Background technique [0002] With the gradual improvement of modern living standards, people's requirements for environmental conditions are getting higher and higher. For this reason, a variety of air purification devices have emerged to address the serious problem of indoor environmental pollution. The most common one is to use chemicals to clean the air. Treatment, such as solid or liquid air fresheners, but this kind of air fresheners more or less contain chemical components that are harmful to the body, and the purification of the air is not thorough enough; Technology to purify the air, most of which use TiO 2 The filter screen performs photocatalytic reaction under ultraviolet light, or it needs to add special catalysts such as nano-silver to carry out catalytic reaction under visible light, but the selection of light s...
