Description

Ultraviolet germicidal lamp

Technical field

The invention relates to a lamp, in particular to an ultraviolet germicidal lamp.

Background technique

Ultraviolet rays have a wide range of uses for disinfection and sterilization, in various public places, homes, etc., it can purify the air and eliminate musty odors. In addition, it can also generate a certain amount of negative oxygen ions. The room that has been disinfected by ultraviolet rays is particularly fresh. Ultraviolet disinfection is the use of appropriate wavelengths of ultraviolet rays to destroy the molecular structure of DNA or RNA in microbial cells, causing growth cell death and (or) regenerative cell death, and achieve the effect of sterilization and disinfection. Under such circumstances, the ultraviolet germicidal lamp is naturally popular as a portable product with ultraviolet disinfection and sterilization functions. However, the UV germicidal lamps currently on the market are of mixed quality. Many UV germicidal lamps have insufficient protection, and are easily damaged if carelessly, and the quality cannot be guaranteed.

Summary of the invention

The purpose of the present invention is to provide an ultraviolet germicidal lamp to solve the insufficient protection and easy damage of the ultraviolet germicidal lamp.

In order to achieve the above objectives, the present invention adopts the following technical solutions:

An ultraviolet germicidal lamp includes a lamp tube, a lamp holder and a lamp shade. The lamp tube is electrically connected to the lamp holder. The lamp shade is arranged around the lamp tube; the lamp holder is provided with a lamp holder protective shell surrounding the lamp holder, and the inner wall of the lamp holder protective shell At least one vertical fixing rod is provided on the fixing rod, and a long hole arranged along the axial direction of the fixing rod is arranged in the fixing rod; a detachable connecting ring is provided on the lamp holder protective shell, and the connecting ring is provided with an A fixing part extending from the side, a fixing hole communicating with the long hole is provided on the fixing part; a lampshade connecting ring connected with the lampshade is formed on the connecting ring, and the outer surface of the lampshade connecting ring is provided with at least one peripherally arranged along the lampshade connecting ring The first limit key; the inner wall of the lampshade is provided with a first limit slot that can be buckled and fixed with the first limit key.

The principle of the above technical solution is as follows: the lamp tube is installed on the lamp socket, the lamp socket is installed in the lamp socket protective shell, and the lamp socket protective shell is provided with a connecting ring. By fixing the fixing hole and the long hole, the connecting ring is connected with The lamp holder protective shell is fixedly connected; and the lampshade and the connecting ring are fixedly connected by fastening and fixing the first limit key and the first limit groove.
