Problems solved by technology

[0007] However, the LED light source is placed inside the cavity, and the photocatalyst forms a cylindrical surface. Only one side can be irradiated by ultraviolet light, and the outer side cannot produce catalytic effect because it cannot be irradiated.
Photocatalyst inefficiency
In addition, the public document with the publication number CN104964180A is similar to the above-mentioned existing device, and also uses single-sided irradiation, which also has the problem of low efficiency

Abstract

The invention relates to a purification device, particularly relates to a miniaturized photocatalyst air purification device and belongs to the technical field of air purification. The miniaturized photocatalyst air purification device disclosed by the technical scheme of the invention comprises an air sucking device for sucking air, a catalytic body for decomposing harmful substances and an ultraviolet LED lamp body for being matched with work of the catalytic body, wherein a light emitting face of the ultraviolet LED lamp body faces the catalytic body; the sucking device, the ultraviolet LEDlamp body and the catalytic body are sequentially distributed in the air flowing direction; air sucked by the sucking device sequentially passes through the ultraviolet LED lamp body and the catalytic body to be exhausted. The miniaturized photocatalyst air purification device disclosed by the invention has the advantages of compact structure, ability in effectively achieving air purification, ability in improving purification efficiency, low use cost, safety and reliability.

Description

technical field [0001] The invention relates to a purification device, in particular to a miniaturized photocatalyst air purification device, which belongs to the technical field of air purification. Background technique [0002] With the development of the economy, the problem of air pollution is becoming more and more serious, so it has received extensive attention, and there are more and more equipment for gas purification, but there are also problems such as many dead zones in the internal gas passage, poor heat dissipation or insufficient To the requirements, low power and other disadvantages. [0003] Photocatalyst technology is a relatively ideal means to deal with indoor air pollution and vehicle interior pollution in the world. It uses light and catalyst (catalyst) combination. Under the irradiation of light, it will produce a photocatalytic reaction similar to photosynthesis. Through this The substances produced by this reaction decompose the harmful substances in...
