[0002] Ultraviolet sterilization and disinfection uses ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA or RNA in the cells of microorganisms, causing productive cell death and regenerative cell death, thereby achieving the effect of sterilization and disinfection. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics, and 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.

[0003] The existing water treatment ultraviolet disinfection device mainly includes a pipe for containing water, and an ultraviolet lamp is placed inside the pipe. When water enters the pipe, the ultraviolet lamp is easily collided with the inner wall of the pipe after being impacted and surged by the water flow, causing damage to the ultraviolet lamp.

[0026] Working principle:

[0027] During installation, first clamp the lower end of the quartz sleeve 8 into the port fixing frame 7, then insert the upper end of the quartz sleeve 8 into the rubber sealing sleeve 5, and make the quartz sleeve 8 and the rubber sealing sleeve 5 be accommodated together in the hollow channel of the external thread base 4, then screw the sealing cover 6 onto the outer surface of the external thread base 4, and press the rubber sealing sleeve 5 through the sealing cover 6, thereby effectively ensuring the sealing effect between the quartz sleeve 8 and the upper end of the pipeline 1, and preventing water from flowing out along the pipeline 1 from the connection of the plug 10 above the tee pipe 2.

[0028] Before use, the ultraviolet lamp 9 is connected to a power source through a plug 10 so that the ultraviolet lamp 9 is powered on. During use, water flows in from the lower end of the pipe 1. During the process of passing through the pipe 1, the ultraviolet rays emitted by the ultraviolet lamp 9 can kill bacteria in the water. The sterilized water flows along the pipe 1 toward the upper end and flows out from the water outlet 3 on the side of the tee pipe 2.

[0029] Embodiment 2, as a further preferred embodiment of embodiment 1, the hollow channel is a truncated cone structure which is wide at the top and narrow at the bottom. The rubber sealing sleeve 5 includes an annular sealing column 51 and a pressed flange 52. The pressed flange 52 is coaxially arranged at the upper end of the annular sealing column 51. The annular sealing column 51 and the pressed flange 52 are an integrated structure.

[0030] By setting the hollow channel to a truncated cone structure that is wide at the top and narrow at the bottom, when the rubber sealing sleeve 5 is pressed by the sealing cover 6, the lower end of the annular sealing column 51 is gradually squeezed by the quartz sleeve 8 and the inner wall of the hollow channel. The tighter the sealing cover 6 is screwed, the better the sealing effect is, thereby effectively ensuring the sealing effect between the quartz sleeve 8 and the inner wall of the hollow channel. In addition, by setting the pressing flange 52, the sealing cover 6 can better apply downward pressure to the rubber sealing sleeve 5, and the pressing flange 52 can also further achieve the sealing effect between the sealing cover 6 and the external thread base 4.

[0034] The lower end of the quartz sleeve 8 can be stably fixed by the clamping block 74. In addition, by providing multiple support plates 73 and setting the support plates 73 parallel to the axis of the pipeline 1, the stability of the connection between the outer ring column 71 and the inner ring column 72 can be enhanced without blocking the water flow.
