Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and more specifically, to an ultraviolet germicidal lamp and a sterilization device. Background Art

[0002] An ultraviolet germicidal lamp is a kind of lamp that uses the germicidal effect of ultraviolet rays for sterilization and disinfection, and is widely used in the disinfection and sterilization of water, air, clothes, etc. Traditional ultraviolet germicidal lamps usually consist of a lamp tube and four electrode pins arranged at both ends of the lamp tube for power connection. According to the different power connection ends of the lamp tube, ultraviolet germicidal lamps can be divided into two types: single-end wiring and double-end wiring. Among them, the single-end wiring ultraviolet germicidal lamp can realize the power connection of the four electrode pins at both ends of the lamp tube by only installing a lamp socket at one end of the lamp tube, and has the advantages of simple structure, cost saving, more beautiful appearance, and more flexible and convenient installation and use, and is used more and more.

[0003] In order to facilitate the processing and setting of the electrode pins and the appearance aesthetics, in the prior art, the four electrode pins of the single-end wiring ultraviolet germicidal lamp have the same length and are cross-symmetric, and an anti-fooling installation structure is realized by setting different spacings. However, this anti-fooling structure has the following problems: (1) The anti-fooling structure is not intuitive enough: Since the spacing differences of the four electrode pins are small, the user needs to try many times to correctly install the ultraviolet germicidal lamp on the lamp socket; (2) The lamp socket is prone to heat: After the ultraviolet germicidal lamp is powered on and used, heat will be generated between the four electrode pins and the power connection end inside the lamp socket. In the prior art, the lengths of the four electrode pins extending into the lamp socket are the same, resulting in a large amount of heat gathering at the same place in the lamp socket, and the lamp socket will be softened after long-term use, shortening the service life of the lamp socket.

[0004] Therefore, there is still room for improvement in the anti-fooling structure and heat dissipation design of the single-end wiring ultraviolet germicidal lamp in the prior art, and a new structural design is needed to solve the above problems. Summary of the Utility Model
