Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet disinfection, in particular to a self-cleaning ultraviolet disinfector. Background Art

[0002] Ultraviolet sterilization and disinfection uses ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growth cell death and / or regenerative cell death, thereby achieving the effect of sterilization and disinfection.

[0003] Ultraviolet sterilizers can also be used in water to disinfect bacteria in the water. Since ultraviolet lamps need to be immersed in water for a long time for disinfection, they are easily attached by dirt or impurities in the water, which greatly reduces the transmittance of the ultraviolet lamps. Most existing methods are to disassemble the ultraviolet lamps, take them out of the sterilizer and wipe them. Although this method can remove dirt or impurities on the ultraviolet lamps, frequent disassembly can easily cause damage to the internal parts and ultraviolet lamps, and the stability and safety are relatively low. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, in the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0036] The utility model provides a self-cleaning ultraviolet disinfector, Figure 1 To the attached Figure 5 It can be seen that a self-cleaning ultraviolet sterilizer mainly includes the following parts or components: a sterilization barrel 10, an ultraviolet lamp 11, a first rotating shaft 13, a rotating ring 14, a wiper plate 15, and a mounting plate 133.

[0037] In the present invention, the disinfection barrel 10 is provided with a first liquid inlet 101, a first liquid outlet 102, a second liquid inlet 103, and a second liquid outlet 104; a plurality of ultraviolet lamps 11 are evenly arranged in the disinfection barrel 10 along the circumferential direction of the disinfection barrel 10; a first rotating shaft 13 is vertically arranged in the disinfection barrel 10 within the plurality of ultraviolet lamps 11 and rotates under the drive of a first motor 12; a rotating ring 14 is sleeved on the first rotating shaft 13 in the disinfection barrel 10 and moves along the axial direction of the first rotating shaft 13 under the drive of a moving assembly 20, and when the first rotating shaft 13 rotates, the rotating ring 14 rotates with the first rotating shaft 13;

[0038] A plurality of wiping plates 15 are arranged in the disinfection barrel 10 and are evenly arranged along the circumferential direction of the first rotating shaft 13. Each wiping plate 15 is connected to the rotating ring 14 and the first rotating shaft 13 through a transmission assembly. When the rotating ring 14 moves, the wiping plate 15 approaches or moves away from the first rotating shaft 13. When the first rotating shaft 13 and the rotating ring 14 rotate, the wiping plate 15 can be rotated synchronously through the transmission assembly. A first brush 151 is provided on the side of the wiping plate 15 facing the ultraviolet lamp tube 11; the mounting plate 133 is vertically arranged in the disinfection barrel 10 between the ultraviolet lamp tube 11 and the inner wall of the disinfection barrel 10, and a second brush 134 is provided on the first side of the mounting plate 133 facing the ultraviolet lamp tube 11. The bottom of the mounting plate 133 is connected to the bottom of the first rotating shaft 13 through the cross plate 131.

[0039] During use, the water to be disinfected enters the disinfection barrel 10 from the first liquid inlet 101, and the ultraviolet lamp 11 disinfects the water and then discharges it from the first liquid outlet 102. When the ultraviolet lamp 11 needs to be cleaned, the moving component 20 drives the rotating ring 14 to move, so that the rotating ring 14 drives the multiple wiping plates 15 to move away from the first rotating shaft 13 at the same time through the multiple transmission components, until the first brush 151 on the wiping plate 15 contacts the ultraviolet lamp 11, and the cleaning liquid is sent from the second liquid inlet 103 to the disinfection barrel 10. After the cleaning liquid is added, The first motor 12 drives the first rotating shaft 13 to rotate, and the first rotating shaft 13 drives the rotating ring 14, the transmission assembly, and the wiping plate 15 to rotate synchronously. The first brush 151 on the wiping plate 15 cleans one side of the ultraviolet lamp 11. At the same time, the first rotating shaft 13 drives the mounting plate 133 to rotate synchronously through the transverse plate 131, so that the second brush 134 on the mounting plate 133 cleans the other side of the ultraviolet lamp 11. Dirt or impurities on the ultraviolet lamp 11 can be removed without disassembling the ultraviolet lamp 11, thereby improving stability and safety.

[0040] Specifically, the mechanism has flexible operability, that is, when not in use, the wiping plate 15 can be retracted to reduce the occupied space area and prevent the ultraviolet light from being blocked from disinfecting the water. When in use, it can be opened to effectively wipe each ultraviolet lamp 11.

[0041] Specifically, the first rotating shaft 13 may have more through holes or an opening at the bottom, so there is no need to consider whether water will accumulate inside the first rotating shaft 13 .

[0042] As an embodiment, Figure 1 To the attached Figure 3It can be seen that the first rotating shaft 13 is a hollow structure with an open top. A long slot hole 135 is provided on the first rotating shaft 13 along its axial direction. The moving assembly 20 includes a first hydraulic cylinder 21 on the disinfection barrel 10; the connecting ring 22 is provided inside the first rotating shaft 13 and is connected to the rotating shaft at the end of the piston rod of the first hydraulic cylinder 21. The connecting plate 23 on the connecting ring 22 passes through the long slot hole 135 and is connected to the rotating ring 14.

[0043] The piston rod of the first hydraulic cylinder 21 drives the connecting ring 22 to move along the axial direction of the first rotating shaft 13. The connecting ring 22 drives the rotating ring 14 to move on the first rotating shaft 13 through the connecting plate 23. After moving to a suitable position, the first motor 12 drives the first rotating shaft 13 to rotate. The first rotating shaft 13 drives the connecting plate 23 to rotate synchronously through the long slot hole 135. The connecting plate 23 drives the connecting ring 22 and the rotating ring 14 to rotate.

[0044] Specifically, a guide key arranged along the axial direction of the first rotating shaft 13 can also be added, and the guide key is slidably connected to the guide groove added to the inner wall of the rotating ring 14. When the first rotating shaft 13 rotates, the rotating ring 14 can be driven to rotate through the cooperation of the guide key and the guide groove.

[0045] In this embodiment, in conjunction with the appendix of the specification Figure 1 To the attached Figure 3 As can be seen, the transmission assembly includes two first connecting rods 16, which are arranged in a scissor-like manner within the disinfection barrel 10 between the wiper plate 15 and the first rotating shaft 13. The first ends of the two first connecting rods 16 are respectively hinged to the wiper plate 15, and the second ends of the two first connecting rods 16 are respectively hinged to the first rotating shaft 13 and the rotating ring 14. When the rotating ring 14 moves, the two first connecting rods 16 swing, thereby driving the wiper plate 15 away from or closer to the first rotating shaft 13.

[0046] As an embodiment, Figure 5 It can be seen that a filter box 30 is provided at the bottom of the disinfection barrel 10, the feed port on the filter box 30 is connected to the second liquid outlet 104, and a filter plate 31 is horizontally provided in the filter box 30 below the feed port.

[0047] The dirt and impurities removed from the ultraviolet lamp 11 will float in the cleaning liquid. If they are directly discharged, it will inevitably cause a waste of resources. Therefore, a filter box 30 is installed to discharge the cleaning liquid containing dirt and impurities from the second liquid outlet 104 into the filter box 30. The dirt and impurities in the cleaning liquid are filtered out by the filter plate 31. The filtered cleaning liquid can be recycled to save resources.

[0048] In this embodiment, in conjunction with the appendix of the specification Figure 5As can be seen, a pusher assembly 40 is provided on the filter plate 31, and a collection box 32 is provided on one side of the pusher assembly 40 to receive debris on the filter plate 31. The pusher assembly 40 includes a pusher plate 41 movably mounted on the filter plate 31, with the pusher plate 41 and the collection box 32 positioned opposite each other; a first screw 42 horizontally disposed within the filter box 30 above the filter plate 31 and driven to rotate by a second motor 44, the first screw 42 being threadedly connected to the pusher plate 41; and an optical axis 43 disposed parallel to the first screw 42 and slidably connected to the pusher plate 41.

[0049] When there is too much dirt and impurities on the filter plate 31, the filtering efficiency of the filter plate 31 will be affected. For this reason, the pushing assembly 40 can prevent excessive accumulation of dirt and impurities, and maintain the filtering efficiency of the filter plate 31. When the pushing assembly 40 is running, the second motor 44 drives the first screw 42 to rotate, and the rotation of the first screw 42 drives the pushing plate 41 to move along the axial direction of the first screw 42. During the movement of the pushing plate 41, the dirt and impurities on the filter plate 31 are pushed into the collection box 32, and the optical axis 43 can maintain the balance of the pushing plate 41 when it moves.

[0050] As an embodiment, Figure 4 As can be seen, the second side surfaces of the transverse plate 131 and the mounting plate 133 are respectively provided with third brushes 132. When the first rotating shaft 13 drives the transverse plate 131 and the mounting plate 133 to rotate, the third brushes 132 can clean the inner wall and bottom of the sterilizing barrel 10, effectively keeping the interior of the sterilizing barrel 10 clean.

[0051] As an embodiment, the outer surface of the wiping plate 15 is arc-shaped, which can effectively prevent the sharp corners from touching the ultraviolet lamp 11 and causing damage to the ultraviolet lamp 11.

[0052] In this embodiment, in conjunction with the appendix of the specification Figure 5 As can be seen, a water drop hole 33 is provided at the bottom of the collection box 32. After the dirt and impurities are pushed to the collection box 32, the redundant cleaning liquid can be discharged from the water drop hole 33, reducing waste.
