Air passing device

Abstract

The invention provides an air passing device, and relates to the technical field of air purification. The air passing device comprises a filtering structure, a light purification part and a reflecting part. The filtering structure is provided with a first side and a second side, the first side is the air inlet front side of the filtering structure, and the second side is the air inlet rear side of the filtering structure. The light purification part is arranged on one side of the first side and the second side of the filtering structure or arranged in the extending direction of one side of the first side and the second side, and is suitable for generating sterilization light rays and irradiating the sterilization light rays on the filtering structure. The reflecting part is arranged on an incident path of the sterilizing light rays irradiated by the light purification part, and the reflecting part is suitable for reflecting the sterilization light rays to the other side of the first side and the second side of the filtering structure. In this way, on the premise that the single light purification part is arranged, the irradiation area of the light purification part on the filtering structure is increased while energy consumption is not increased, and multi-directional sterilization and disinfection of the filtering structure are achieved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air passage device. Background technique [0002] Air purifiers, also known as "air cleaners", can absorb, decompose or transform various air pollutants, effectively improve air cleanliness, and provide users with clean and safe air. Today, people's requirements for air purifiers are not only to filter the air, but also hope to kill the bacteria attached to the filter structure inside the purifier. [0003] Mature technologies for sterilization and disinfection of filter structures are mainly: high-temperature sterilization and ultraviolet sterilization. Among them, the high-temperature heating sterilization treatment method has the problems of large components and high prices. The ultraviolet lamp itself is low in cost and can destroy microbial cell bodies through the emitted ultraviolet rays The molecular structure in it can cause cell death, so as to achieve the b...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that a single ultraviolet lamp can only irradiate the air inlet front side or the air inlet rear side of the filter structure in the prior art in which the filter structure is sterilized by ultraviolet light, resulting in incomplete sterilization. Thereby providing a wind passing device
