Problems solved by technology

During the use of the germicidal lamp, the germicidal lamp gradually heats up with the increase of the working time. The temperature of the germicidal lamp itself will affect the ultraviolet illuminance of the germicidal lamp and the service life of the germicidal lamp. The current germicidal lamp is generally installed with a fan. The lamp tube dissipates heat, and the germicidal lamp with this structure has poor heat dissipation effect and cannot greatly reduce the temperature of the lamp tube, so that the existing germicidal lamps have the problems of low ultraviolet illuminance and short service life

Abstract

The invention relates to an excimer sterilizing lamp which comprises a lamp tube, a first electrode and a second electrode; an air storage cavity is formed in the lamp tube and is kept airtight with the outside; a heat pipe and a first radiator are further included; an inner through hole is formed in the lamp tube; the air storage cavity is arranged around the inner through hole of the lamp tube,and the air storage cavity is filled with working gas; the first electrode is arranged in the inner through hole of the lamp tube in a penetrating manner; the second electrode is arranged on the outercircumferential surface of the lamp tube, and a high-voltage electric field formed by matching the first electrode and the second electrode penetrates through the air storage cavity of the lamp tube;one part of the heat pipe penetrates into the inner through hole of the lamp tube, and the other part of the heat pipe is positioned outside the lamp tube; the first radiator is located beside the lamp tube, and the first radiator is connected with the part, located outside the lamp tube, of the heat pipe to dissipate heat. The excimer sterilizing lamp has the advantages of simple structure, reasonable design, good lamp tube heat dissipation effect, high ultraviolet illuminance, long service life and the like. The invention further relates to an excimer sterilizing device.

Description

technical field [0001] The invention relates to the technical field of sterilization and disinfection equipment, in particular to an excimer germicidal lamp; the invention also relates to an excimer sterilization device. Background technique [0002] The germicidal lamp tubes equipped with the existing sterilizing devices all contain mercury. The principle is that the temperature in the germicidal lamp tube is raised by heating to generate mercury vapor, and as the temperature rises, the mercury vapor is also excited and decomposes. emits ultraviolet light. During the use of the germicidal lamp, the germicidal lamp gradually heats up with the increase of the working time. The temperature of the germicidal lamp itself will affect the ultraviolet illuminance of the germicidal lamp and the service life of the germicidal lamp. The current germicidal lamp is generally installed with a fan. The lamp tube dissipates heat, and the germicidal lamp with such a structure has a poor he...
