[0002] The structure of the germicidal lamp can refer to the Chinese utility model patent with the application number 201920967269.5 and the name of an all-round germicidal UVC lamp. In recent years, with the progress of technology and the promotion of environmental protection regulations, due to problems such as short lifespan, low energy efficiency, and containing harmful substances, UV mercury lamps have gradually been replaced by more efficient and environmentally friendly LED light sources. LED light sources have advantages such as high energy efficiency, instant response, environmental protection, low heat effect, long lifespan, wavelength selectivity, and easy control, making them dominant in multiple application fields. In order to achieve all-round disinfection for the existing LED germicidal lamp in the water dispenser tank, usually more than two germicidal lamp components need to be installed in the tank, which has the disadvantages of complex installation structure, poor heat dissipation effect, and unstable performance.
