Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of germicidal lamps, in particular to an ultraviolet germicidal lamp. Background Art
[0002] Ultraviolet disinfection technology is based on the principles of modern epidemiology, medicine and photodynamics. It uses specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to irradiate flowing water, directly killing various bacteria, viruses, parasites, algae and other pathogens in the water, thereby achieving the purpose of disinfection. The lamp tube of the ultraviolet disinfection lamp is made of ultraviolet-transparent glass or quartz glass, allowing ultraviolet rays to penetrate through the glass tube wall, thereby achieving the purpose of disinfection. It is widely used in hospitals, laboratories, homes, office environments and other places.
[0003] Existing ultraviolet sterilization lamp beads generally include a quartz bulb shell and a filament encapsulated inside. The existing filament structure is generally a drop-down type, with the lowest point of the filament suspended and connected to the glass bead bracket. At the same time, the glass bead bracket is used to fix the lamp corner. The lamp corner is welded to the molybdenum sheet, and the molybdenum sheet is welded to the molybdenum rod. It is processed through a series of processes such as clamping, baking, and high vacuum. The overall structure is relatively complex and the processing process is long. We have made improvements to this. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the existing ultraviolet germicidal lamp has a relatively complex overall structure and a relatively long processing process.

Compared with the prior art, the glass bead bracket workpiece and related processes are saved, and the filament does not need to be hung on the glass bead bracket, which is replaced by two groups of lamp horns. By changing the shape of the filament, the structure is simpler, more stable and reduces the cost.
[0006] Preferred technical solution 1: The lamp corners are arranged in a Z-shape bend, and the upper end spacing of the two groups of lamp corners is greater than the lower end spacing.
[0007] Preferred technical solution 2: The bulb shell is made of quartz glass and is pressed and formed.
