Description

Technical Field

[0001] The invention relates to the technical field of UVC photocatalyst sterilization equipment, in particular to a UVC photocatalyst sterilization equipment with a self-checking and maintenance function. Background Art

[0002] UVC photocatalyst sterilization equipment is a device that uses ultraviolet rays (UVC) of a specific wavelength to destroy the DNA structure of microorganisms, thereby achieving a sterilization effect. Photocatalyst is a photocatalyst that can promote chemical reactions under light conditions and enhance the sterilization effect. This type of equipment is usually used in fields such as air purification, water treatment and surface disinfection. It can effectively kill viruses, bacteria and fungi without producing harmful ozone derivatives.

[0003] The Chinese patent application with application number CN202121383511.8 discloses a photocatalyst ultraviolet sterilization and disinfection device, including a shell with an air inlet and an air outlet, wherein an ultraviolet emitting mechanism, a blowing mechanism and a photocatalyst mechanism are arranged in the shell, and the ultraviolet emitting mechanism includes at least one group of UVA emitting components and at least one group of UVC emitting components, and the UVA emitting components are facing the photocatalyst mechanism. Under the action of the blowing mechanism, air will enter the shell from the air inlet and be discharged from the air outlet: during the flow of air, the UVC emitting component will emit UVC to kill bacteria and viruses in the air, and the UVA emitting component will emit UVA to the photocatalyst mechanism. The titanium dioxide in the photocatalyst mechanism will absorb UVA and convert water molecules and oxygen in the air into strong oxidizing groups and hydroxyl free radicals. The strong oxidizing groups and hydroxyl free radicals can degrade toxic and harmful gases in the air, and can kill a variety of bacteria and viruses. This application improves the sterilization effect;

[0004] Although such a setting will allow air to enter the casing from the air inlet and be discharged from the air outlet under the action of the blowing mechanism: during the flow of air, the UVC emitting component will emit UVC to kill bacteria and viruses in the air, but there is usually dust in the air. During the continuous flow of air, the dust in the air will adhere to the surface of the UVC emitting component. When used for a long time, dust may accumulate too much, resulting in thick dust on the surface of the UVC emitting component, affecting the irradiation effect of ultraviolet rays on bacteria in the air. It is necessary to set up a corresponding air filtration structure. In addition, it is also necessary to set up a corresponding cleaning structure to reduce the frequency of replacement of the air filtration structure and enhance the continuity of use.
