[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1, as Figures 1 to 6 As shown, a flow-through ultraviolet sterilization device includes an outer tube 1, an upper sleeve 2 fixedly installed at the upper end of the outer tube 1, a lower sleeve 3 fixedly installed at the lower end of the outer tube 1, a water outlet 4 provided on the side of the upper sleeve 2, a plurality of lamp sleeve mounting holes 5 evenly opened on the upper end face of the upper sleeve 2, an upper cover 6 installed on the upper sleeve 2, a plurality of wire outlet holes 23 opened on the surface of the upper cover 6, the wire outlet holes 23 being vertically aligned with the lamp sleeve mounting holes 5; a wire outlet plug 7 is installed on the wire outlet hole 23;

[0024] The lower end of the lower sleeve 3 is closed, and an inlet 8 is provided on the side of the lower sleeve 3. A fixing plate 9 is fixedly installed at the bottom of the inner cavity of the lower sleeve 3. Several rubber sleeves 10 are fixedly installed on the surface of the fixing plate 9. The rubber sleeves 10 are vertically aligned with the lamp sleeve mounting hole 5. Multiple lamp sleeves 11 are arranged parallel to each other along the axial direction in the inner cavity of the outer sleeve 1. The lower end of the lamp sleeve 11 is closed, and the lower end of the lamp sleeve 11 is fixedly installed in the middle of the rubber sleeves 10. The upper end of the lamp sleeve 11 passes through the outlet hole 23 and is sealed to the outlet hole 23. An ultraviolet lamp 12 is installed inside the lamp sleeve 11. The upper end of the ultraviolet lamp 12 is connected to one end of the cable, and the other end of the cable passes through the outlet plug 7 and is connected to the external circuit.

[0025] Working principle:

[0026] During installation, first open the top cover 6, then insert each lamp sleeve 11 downwards through the lamp sleeve mounting hole 5 into the outer sleeve 1, ensuring that the lower end of each lamp sleeve 11 is inserted and fixed into the rubber sleeve 10 on the surface of the fixing plate 9, thus achieving the installation and fixing of each lamp sleeve 11. Next, insert each ultraviolet lamp 12 from the upper end of the lamp sleeve 11 into the interior of the lamp sleeve 11, ensuring that the cable at the upper end of each ultraviolet lamp 12 passes through the through hole in the middle of the outlet plug 7 to lead outwards. Then, seal the top cover 6 onto the upper end face of the upper sleeve 2, and then seal each outlet plug 7 into each outlet hole 23, thus achieving a sealing and closing effect for each ultraviolet lamp 12. This effectively prevents water from flowing into each lamp sleeve 11 along the outer sleeve 1. The entire installation process is convenient and quick. When a specific UV lamp 12 needs to be repaired or replaced, the corresponding outlet plug 7 can be removed from the corresponding outlet hole 23 to remove and replace the corresponding UV lamp 12. It is not necessary to completely dismantle the entire UV sterilization device, which makes maintenance and repair work easier during use.

[0027] When in use, first connect the cables of each ultraviolet lamp 12 to the external circuit to power on each ultraviolet lamp 12. During use, the water first enters the lower sleeve 3 through the inlet 8, then passes through the outer sleeve 1 and flows out from the outlet 4 on the side of the upper sleeve 2. During the flow through the outer sleeve 1, the ultraviolet rays emitted by each ultraviolet lamp 12 inside the outer sleeve 1 can kill bacteria in the water flow.

[0028] In Example 2, as a further preferred embodiment of Example 1, a flange edge 13 is provided on the outer periphery of the upper end of the upper sleeve 2. Multiple sets of rotating shaft seats 14 are evenly provided on the lower surface of the flange edge 13. A screw 15 is rotatably connected to the middle of each set of rotating shaft seats 14 through a pin. Several vertical slots 16 are correspondingly opened on the outer periphery of the flange edge 13 and the outer periphery of the upper cover 6. The screw 15 corresponds to the vertical slots 16. A nut 17 is threadedly connected to the screw 15. The nut 17 abuts against the upper surface of the upper cover 6.

[0029] Therefore, when sealing the upper cover 6 onto the upper sleeve 2, the vertical slots 16 on the outer periphery of the upper cover 6 can be aligned one by one with the vertical slots 16 on the flange edge 13 of the upper sleeve 2. Then, each screw 15 is rotated upwards so that the screw 15 is inserted into each vertical slot 16. After that, the nuts 17 are tightened so that each nut 17 is pressed against the upper surface of the upper cover 6. Thus, the stability of the connection between the upper cover 6 and the upper sleeve 2 is effectively guaranteed by the joint pressing and fixing effect of each nut 17 on the outer periphery of the upper cover 6.

[0030] In embodiment three, as a further preferred embodiment one, a waterproof top cover 18 is provided on the upper surface of the top cover 6. All cable outlets 23 are located within the waterproof top cover 18. The bottom surface of the waterproof top cover 18 has several cable outlet slots 19, the number of which is the same as the number of ultraviolet lamps 12. The cable passes through the cable outlet plug 7 and then exits through the cable outlet slots 19. The waterproof top cover 18 provides waterproof protection for each cable outlet 23. Furthermore, by creating the cable outlet slots 19 on the bottom surface of the waterproof top cover 18, the cables of each ultraviolet lamp 12, after exiting through the central through-hole of the cable outlet plug 7, can be led out through the cable outlet slots 19 and connected to an external circuit.

[0031] In Example 4, as a further preferred embodiment of Example 3, a cable support frame 20 is fixedly installed on the upper surface of the cover 6. The cables are movably connected to the cable support frame 20, and the cable support frame 20 is close to the outlet slot 19. This allows the cables of each ultraviolet lamp 12 to be orderly connected to the cable support frame 20 after being led out from the central through hole of the outlet plug 7, thus avoiding the problem of inconvenient maintenance caused by messy cables.

[0032] In Example 5, as a further preferred embodiment of Example 1, a rubber sleeve 21 is fixedly installed inside the lamp sleeve mounting hole 5. The lamp sleeve 11 is sealed to the rubber sleeve 21, and a sealing gasket 22 is provided at the upper end of the rubber sleeve 21. The sealing gasket 22 is pressed between the upper sleeve 2 and the upper cover 6. The rubber sleeve 21 effectively ensures the sealing connection between the outer surface of each lamp sleeve 11 and the lamp sleeve mounting hole 5, thereby effectively preventing water from entering each lamp sleeve 11 along the inner side of the outer sleeve 1. Furthermore, by providing the sealing gasket 22 at the upper end of the rubber sleeve 21, the sealing gasket 22 is located between the upper sleeve 2 and the upper cover 6. Therefore, when the nut 17 is tightened so that the upper cover 6 is pressed tightly against the upper end face of the upper sleeve 2, the sealing gasket 22 can more effectively seal the lamp sleeve mounting hole 5 through the pressing action between the upper sleeve 2 and the upper cover 6. Moreover, the greater the tightening force of the upper cover 6, the better the sealing effect of the sealing gasket 22.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
