The input end of the power adapter 4 is connected to a power cord 41. The power cord 41 extends out of the end cap 1 through the wire outlet 11 so that the power cord 41 is connected to the power supply. The power adapter 4 can convert the voltage of the power supply from 220V to 24-36V and output the power cord from the output of the power adapter 4. End output, the output end of the power adapter 4 is connected to the first connector 42, the connector 2 is provided with a through hole 21 respectively connected to the interior of the end cover 1 and the interior of the shell 3, the lampshade 6 is arranged in the shell 3, and the end of the lampshade 6 close to the connector 2 is open and sealed with the connector 2, the ultraviolet lamp 5 is installed in the lampshade 6, the ultraviolet lamp 5 is connected to the first connector 42 through the second connector 51, the first connector 42 matches the second connector 51 and can be disassembled and separated, the shell 3 is provided with a water inlet 31 and a water outlet 32, and there is a distance between the inner wall of the shell 3 and the outer wall of the lampshade 6 to form a circulation channel.

[0022] The working principle of this embodiment is as follows: when working, the power cord 41 is connected to the power supply, and the ultraviolet lamp 5 is connected to the first connector 42 through the second connector 51. The power adapter 4 converts the voltage of the power supply for the ultraviolet lamp 5 to work. The ultraviolet lamp 5 works within a safe voltage range and has high safety. The liquid that needs to be sterilized is transported to the shell 3 through the water inlet 31, then flows in the circulation channel, and finally discharged from the water outlet 32. During this process, the ultraviolet lamp 5 in the lampshade 6 emits ultraviolet rays to sterilize the liquid, and the sterilization effect is good. The lampshade 6 is sealed and connected to the connecting piece 2, so that the ultraviolet lamp 5 is separated from the liquid in the shell 3, ensuring the normal operation of the ultraviolet lamp 5.

During assembly, the first positioning block 61 and the straight pipe of the lamp tube group 52 are first assembled and connected, and the second positioning block 62 and the curved pipe of the lamp tube group 52 are assembled and connected. Then, the first positioning block 61, the lamp tube group 52 and the second positioning block 62 are placed together in the lampshade 6, so that the first positioning block 61 and the second positioning block 62 respectively cooperate with the inside of the lampshade 6, thereby realizing the installation and fixation of the lamp tube group 52, and easy disassembly and assembly.
