Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet disinfection equipment, in particular to a filter improvement device for an air conditioner built in an ultraviolet disinfection equipment. Background Art

[0002] Ultraviolet disinfection equipment refers to a disinfection device that uses high-intensity ultraviolet germicidal lamps to destroy the internal structures of bacteria and viruses such as DNA, thereby killing pathogenic microorganisms in water. Ultraviolet disinfection equipment is generally equipped with a control cabinet. In the process of using the ultraviolet disinfection equipment control cabinet, in order to cool the cabinet electrical components, a built-in air conditioner is generally provided in the ultraviolet control cabinet. During the use of the built-in air conditioner in the ultraviolet control cabinet, there are more impurities in the air. At this time, a filter is required on the air conditioner outdoor unit to filter out impurities. During the use of the filter, the filter must be cleaned by frequently cleaning the filter. In order to improve the cleaning method of frequently cleaning the filter, a filter improvement device for the built-in air conditioner in ultraviolet disinfection equipment is often required.

[0003] However, in the prior art, the filter on the air-conditioning outdoor unit is generally cleaned by frequently cleaning a single filter. Since there is no placement device on the air-conditioning outdoor unit, the roll-type filter cannot be placed on the air-conditioning outdoor unit. This not only makes it impossible to replace the filter in the form of a roll of paper, but also makes it impossible to reduce the number of times the filter is cleaned, which makes it time-consuming and labor-intensive, and increases the probability of water on the filter entering the air-conditioning outdoor unit, thereby making it more troublesome to use and reducing its improvement effect. In the prior art, it is generally a single filter. Since it is not a roll-type filter, there is no limiting device on the roll-type filter. This will cause the roll-type filter to shake when it is pulled, thereby causing its position to deviate, reducing its use effect. Utility Model Content
