DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, it is a structural diagram of a water purification device with a sterilization function provided by an embodiment of the present invention, comprising a box body 1, a partition 2 is fixedly installed in the inner cavity of the box body 1, and the partition 2 divides the inner cavity of the box body 1 into a debris removal cavity 21 and a water purification cavity 22, a water inlet 11 connected to the water purification cavity 22 is arranged on the side wall of the box body 1, a drain pipe 12 connected to the water purification cavity 22 is fixedly installed on the bottom wall of the box body 1, and a filtering mechanism 3 is arranged in the inner cavity of the box body 1, and the filtering mechanism 3 includes a filter screen 31, a positioning component 32, a purge assembly 33, and a filter assembly 34. The filter screen 31 is an annular belt-shaped structure. The positioning component 32 is located in the inner cavity of the box body 1 and is connected to the filter screen 31. The positioning component 32 is used to position the filter screen 31 in the impurity removal chamber 21 and the water purification chamber 22. The purge component 33 is located in the impurity removal chamber 21 and above the filter screen 31. The guide component 34 is located in the impurity removal chamber 21 and below the filter screen 31. The positioning component 32, the purge component 33 and the guide component 34 are respectively connected to the drive component 35. The driving assembly 35 is connected to the housing 1, and the driving assembly 35 controls the filter screen 31 to rotate in the impurity removal chamber 21 and the water purification chamber 22 by cooperating with the positioning assembly 32. When the filter screen 31 rotates, the driving assembly 35 cooperates with the purge assembly 33 to blow high-pressure air on the surface of the filter screen 31, and the driving assembly 35 cooperates with the guide assembly 34 to transport the impurities cleaned from the surface of the filter screen 31 to the outside of the housing 1. The bottom wall of the water purification chamber 22 is provided with a plurality of groups of ultraviolet lamp posts 4. A cleaning assembly 5 that cooperates with the ultraviolet lamp column 4 is arranged in the cavity 22, and the cleaning assembly 5 includes a positioning ring 51 and an adjusting portion 52. The positioning ring 51 is sleeved on the outside of the ultraviolet lamp column 4, and a cleaning ring 511 is fixedly installed on the inner wall of the positioning ring 51. The cleaning ring 511 is made of sponge material, one end of the adjusting portion 52 is connected to the purge assembly 33, and the other end of the adjusting portion 52 is connected to the positioning ring 51. The adjusting portion 52 is used to control the positioning ring 51 and the cleaning ring 511 to reciprocate in the vertical direction outside the ultraviolet lamp column 4.

[0026] When in use, the sewage to be purified is transported to the water cleaning chamber 22 through the water inlet 11. The filter 31 in the water cleaning chamber 22 can filter the sewage. The impurities in the sewage will adhere to the surface of the filter 31. After the sewage is filtered, the ultraviolet lamp column 4 can irradiate and sterilize the sewage, and then the disinfected sewage can be discharged through the drain pipe 12.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the guide assembly 34 includes a horizontal cylinder 341 fixedly installed in the de-impurity chamber 21 and located directly below the purge pipe 332, the upper surface of the horizontal cylinder 341 is provided with an opening, one end of the horizontal cylinder 341 extends to the outside of the box body 1, and a rotating column 342 is rotatably installed in the horizontal cylinder 341, and a spiral auger 343 is provided on the surface of the rotating column 342.

[0032] The high-pressure air blows the impurities off the surface of the filter 31, and the impurities fall into the horizontal cylinder 341.

The spiral auger 343 can easily push the impurities in the horizontal cylinder 341 to the outside of the box body 1.

[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, as a preferred embodiment of the present invention, the driving assembly 35 includes a group of upper bearing rollers 321 and a group of rotating columns 333, one end of which extends to the outside of the box body 1 and are respectively fixedly installed with first synchronous gear plates 351, the two groups of first synchronous gear plates 351 are commonly connected with a first synchronous belt 352, the other end of the upper bearing roller 321, the rotating column 342 and one end of another group of rotating columns 333 extend to the outside of the box body 1 and are respectively fixedly installed with second synchronous gear plates 353, the surfaces of multiple groups of second synchronous gear plates 353 are commonly connected with second synchronous belts 354, and a motor 355 is fixedly installed on the side wall of the box body 1, and the output shaft of the motor 355 is connected to the upper bearing roller 321.

[0034] When in use, the motor 355 drives the upper bearing roller 321 to rotate, and the upper bearing roller 321 cooperates with the lower bearing roller 322 to drive the filter screen 31 to rotate in the impurity removal chamber 21 and the water purification chamber 22. When the upper bearing roller 321 rotates, it drives the first synchronous toothed disc 351 to rotate. The two sets of first synchronous toothed discs 351 cooperate with the first synchronous belt 352 to drive the rotating column 333 to rotate synchronously. When the upper bearing roller 321 rotates, it drives the second synchronous toothed disc 353 to rotate. The multiple sets of second synchronous toothed discs 353 cooperate with the second synchronous belt 354 to drive the rotating column 342 and the rotating column 333 to rotate synchronously.

[0035] like Figure 3 , Figure 4 , Figure 8 As shown, as a preferred embodiment of the present invention, the adjusting portion 52 includes vertical grooves respectively opened on the two side walls opposite to each other in the inner cavity of the box body 1, and upper sliding blocks 521 slidably connected to the vertical grooves are fixedly installed at both ends of the extrusion plate 335, and a connecting rod 523 is fixedly installed on the bottom wall of the upper sliding block 521, and a lower sliding block 522 slidably connected to the vertical grooves is fixedly installed on the bottom end of the connecting rod 523, and multiple groups of lower sliding blocks 522 are commonly fixedly installed with a bottom plate 524, and multiple groups of brackets 525 are fixedly installed on the side walls of the bottom plate 524, and the end of the bracket 525 away from the bottom plate 524 is connected to the positioning ring 51.

[0036] When the extrusion plate 335 moves in the vertical direction, it drives the upper sliding block 521 to move synchronously in the vertical direction in the vertical groove. The upper sliding block 521 cooperates with the connecting rod 523 to drive the lower sliding block 522 to move synchronously. Multiple groups of lower sliding blocks 522 drive the bottom plate 524 to move back and forth in the vertical direction in the clean water chamber 22. The bottom plate 524 cooperates with the bracket 525 to drive the positioning ring 51 and the cleaning ring 511 to move back and forth in the vertical direction on the outside of the ultraviolet lamp column 4. The cleaning ring 511 can automatically clean impurities and scale attached to the surface of the ultraviolet lamp column 4.

[0039] The working principle of the present invention is: when in use, the sewage to be purified is transported to the water purification chamber 22 through the water inlet 11, and the filter 31 in the water purification chamber 22 can filter the sewage, and the impurities in the sewage will adhere to the surface of the filter 31. After the sewage is filtered, the ultraviolet lamp column 4 can irradiate and sterilize the sewage, and then the disinfected sewage can be discharged through the drain pipe 12. When filtering the sewage, the motor 355 drives the upper bearing roller 321 to rotate, and the upper bearing roller 321 cooperates with the lower bearing roller 322 to drive the filter 31 to rotate in the impurity removal chamber 21 and the water purification chamber 22. When the upper bearing roller 321 rotates, it drives the first synchronous gear disc 351 to rotate, and the two sets of first synchronous gear discs 351 cooperate with the first synchronous belt 352 to drive the rotating column 333 to rotate synchronously.

The extrusion plate 335 can compress the airbag 338 when moving downward. The airbag 338 cooperates with the conduit 339 to transport high-pressure air to the purge pipe 332 and further blow it toward the surface of the filter 31. The high-pressure air can easily blow impurities off the surface of the filter 31. The high-pressure air blows impurities off the surface of the filter 31, and the impurities fall into the horizontal cylinder 341. The rotating column 342 drives the spiral auger 343 to rotate, and the spiral auger 343 can easily push the impurities in the horizontal cylinder 341 to the outside of the box body 1.

[0041] When the extrusion plate 335 moves in the vertical direction, it drives the upper sliding block 521 to move synchronously in the vertical direction in the vertical groove. The upper sliding block 521 cooperates with the connecting rod 523 to drive the lower sliding block 522 to move synchronously. Multiple groups of lower sliding blocks 522 drive the bottom plate 524 to move back and forth in the vertical direction in the clean water chamber 22. The bottom plate 524 cooperates with the bracket 525 to drive the positioning ring 51 and the cleaning ring 511 to move back and forth in the vertical direction on the outside of the ultraviolet lamp column 4. The cleaning ring 511 can automatically clean impurities and scale attached to the surface of the ultraviolet lamp column 4.

Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
