[0024] Example 1 provides a drinking water ultraviolet disinfection device:

[0025] The water cylinder 10 is provided with a water inlet pipe 11 and a water outlet pipe 12 . The water inlet pipe 11 is higher than the water outlet pipe 12 . Drinking water enters the water cylinder 10 through the water inlet pipe 11 and is then discharged through the water outlet pipe 12 .

[0026] Control valves 13 are installed on the water inlet pipe 11 and the water outlet pipe 12 respectively, and the control valves 13 control the water inlet and water outlet.

[0027] The isolation assembly 20 includes a plurality of guide rods 21 fixed to the water filter cylinder 10, and a cover plate 22 is sleeved on the plurality of guide rods 21. The cover plate 22 can be buckled on the top opening of the water filter cylinder 10 to form a closure. The cover plate 22 is buckled on the top opening of the water filter cylinder 10 to form a closure to isolate the drinking water and prevent external impurities from entering the water filter cylinder 10 and affecting the quality of the drinking water. The cover plate 22 can be lifted upward along the plurality of guide rods 21 to facilitate cleaning of the water filter cylinder 10.

[0028] A plurality of through holes are provided on the cover plate 22, and the plurality of through holes are circumferentially distributed. The ultraviolet disinfection assembly 30 includes a plurality of groups of ultraviolet lamp bodies 31, and each group of ultraviolet lamp bodies 31 vertically corresponds to a through hole. Each group of ultraviolet lamp bodies 31 is controlled by a separate wiring harness switch. The ultraviolet lamp body 31 can be inserted into the inner cavity of the water cylinder 10 along the through hole, so that when the drinking water flows through the inner cavity of the water cylinder 10, it is irradiated with ultraviolet rays and disinfected, so that the DNA and RNA structures of bacteria, viruses, and algae biological cells in the drinking water are destroyed, and cell regeneration cannot be carried out, thereby achieving the purpose of disinfecting and purifying the water.

[0029] A ring plate 32 is provided at the top of each set of ultraviolet lamp bodies 31. A drive assembly 40 is used to insert or remove a set of ultraviolet lamp bodies 31 from or into the inner cavity of the water cylinder 10. The drive assembly 40 includes a bracket 41 rotatably mounted on the cover plate 22. An electric cylinder body 42 is mounted on the top of the bracket 41. The movable rod of the electric cylinder body 42 extends vertically downward and is connected to a lifting block 43. The lifting block 43 has a transverse slot 44 for the ring plate 32 to enter.

[0030] When the ultraviolet lamp body 31 needs to be maintained, the bracket 41 is first rotated to drive the lifting block 43 to move circumferentially, so that the ring plate 32 corresponding to the ultraviolet lamp body 31 that needs maintenance enters the transverse groove 44, and then the electric cylinder body 42 is controlled to drive the lifting block 43 to move upward. The lifting block 43 pulls the ring plate 32, thereby driving the ultraviolet lamp body 31 to be pulled out upward along the through hole, so that the ultraviolet lamp body 31 is separated from the inner cavity of the water filter 10. The ultraviolet lamp body 31 is maintained on the water filter 10. After the maintenance is completed, the electric cylinder body 42 is controlled to drive the lifting block 43 to move downward, and the ultraviolet lamp body 31 is reinserted into the inner cavity of the water filter 10. There is no need to manually insert or remove the ultraviolet lamp body 31, the operation is convenient, and the disinfection of drinking water is not stopped during the maintenance operation.

[0031] Example 2: Provide a drinking water ultraviolet disinfection device:

[0032] A lifting block 23 is screwed onto each guide rod 21 , and the lifting block 23 can support the cover plate 22 . When the cover plate 22 is lifted upward along the guide rods 21 to clean the water cylinder 10 , the lifting block 23 can be rotated upward to support the cover plate 22 .

[0033] An indicator light 33 is provided on the upper end of each set of ring plates 32 , and the indicator light 33 is used to display the working status of the ultraviolet lamp body 31 .

[0034] A rubber ring 34 is provided at the lower end of each set of ring plates 32. The rubber ring 34 can abut against the inner wall of the through hole, thereby sealing the through hole.

[0035] The upper and lower ends of the lifting block 43 are respectively screwed to the limiting columns 45, and the limiting columns 45 can be extended into the transverse groove 44 to abut the ring plate 32. After the ring plate 32 enters the transverse groove 44, the two limiting columns 45 can be rotated to extend into the transverse groove 44 to abut the ring plate 32, so that the stability is good during the insertion and removal of the ultraviolet lamp body 31.

[0036] The control valve 13 is connected to the signal of the electric cylinder body 42. When the ultraviolet lamp body 31 is maintained, the control valve 13 receives the working signal of the conductive cylinder body 42, and controls the water inlet and outlet of the water inlet pipe 11 and the water outlet pipe 12 to reduce the water volume, so as to avoid the lack of a group of ultraviolet lamp bodies 31 irradiation affecting the disinfection effect of drinking water.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
