Description

Technical Field

[0001] This utility model belongs to the field of germicidal lamp technology, specifically relating to a lifting germicidal lamp. Background Technology

[0002] Humans have an increasing need to eliminate viruses, bacteria, and mites. However, current methods for eliminating these viruses, bacteria, and mites mainly involve spraying and cleaning with chemical disinfectants. Many chemical disinfectants are consumed in large quantities, are costly, and can even be harmful to humans. Another commonly used sterilization method is the use of ultraviolet (UV) germicidal lamps. The effective area of ​​existing UV sterilization is typically within a certain range around the UV lamp, generally 1.5-2 meters. Traditional germicidal lamps are fixed in location and their height is not adjustable. When used in high spaces, the distance from the surface to be sterilized is too great, exceeding the effective sterilization distance and limiting the sterilization range. Utility Model Content
