The wastewater multi-stage purification mechanism also includes a rack 10, the lower end of the rack 10 is fixedly connected to the bottom of the wastewater treatment box 3, an externally threaded pipe 15 is arranged on the right side of the filter box 5, the left end of the externally threaded pipe 15 is fixedly connected to the right side of the filter box 5, the externally threaded pipe 15 is communicated with the filter box 5, an internally threaded pipe 14 is rotatably connected inside the externally threaded pipe 15, an external drain port 11 is arranged on the top of the externally threaded pipe 15, an internal drain port 22 is arranged on the top of the internally threaded pipe 14, a gear 13 is arranged on the right end of the internally threaded pipe 14, the internally threaded pipe 14 is fixedly connected to the gear 13, and the gear 13 is meshed with the rack 10. The wastewater conveying assembly includes a conveying pipe 19, the upper and lower ends of which are respectively fixedly connected to the filter boxes 5 on the upper and lower sides, the conveying pipe 19 is connected to the filter box 5, a vertical rod 21 is arranged inside the conveying pipe 19, a plurality of cross rods 18 are fixedly arranged at the bottom end of the vertical rod 21, the cross rods 18 are fixedly connected to the inner wall of the conveying pipe 19, an elastic sleeve 16 is sleeved on the outer side of the vertical rod 21, the elastic sleeve 16 is conical, and the top of the elastic sleeve 16 is fixedly connected to the top of the vertical rod 21. The wastewater conveying assembly also includes a plurality of second springs 20, which are arranged around the vertical rod 21, one end of the second spring 20 is fixedly connected to the vertical rod 21, and the other end of the second spring 20 is fixedly connected to the inner wall of the elastic sleeve 16. The wastewater conveying assembly also includes a silicone ring 17, which is sleeved on the bottom of the elastic sleeve 16 and is fixedly connected to the bottom of the elastic sleeve 16.

[0035] When in use, the connecting hose 26 is passed through the through hole 2 to extend the connecting hose 26 to the outside of the wastewater treatment box 3, and the wastewater is introduced into the uppermost filter box 5 through the connecting hose 26 and the water inlet pipe 25. After the wastewater is filtered by the activated carbon in the uppermost filter box 5, it is discharged into the wastewater treatment box 3 through the inner drain port 22 and the outer drain port 11 in sequence, and then discharged through the drain pipe 4. At this time, since the delivery pipe 19 between the uppermost filter box 5 and the filter box 5 below it is blocked by the elastic sleeve 16 and the silicone ring 17, the wastewater in the uppermost filter box 5 cannot enter the filter box 5 below it through the delivery pipe 19.

[0036] After the wastewater is filtered by the activated carbon in the top filter box 5 for a period of time, the impurities in the wastewater are continuously accumulated in the top filter box 5, so that the overall weight of the top filter box 5 is continuously increased, so that the top filter box 5 slides down along the guide rod 6 to stretch the first spring 8, and the filter box 5 drives the gear 13 to move down synchronously through the external threaded tube 15 and the internal threaded tube 14. Since the gear 13 is meshed with the rack 10, the gear 13 rotates during the downward movement, and the gear 13 drives the internal threaded tube 14 to rotate, so that the outer drain port 11 and the inner drain port 22 that originally overlapped with each other rotate relative to each other. The outer drain port 11 and the inner drain port 22 are moved, so that the overlapping area of ​​the outer drain port 11 and the inner drain port 22 is continuously reduced, thereby reducing the drainage volume of the wastewater discharged through the inner drain port 22 and the outer drain port 11, so that the water pressure of the uppermost filter box 5 is increased. Under the action of the water pressure, the water flow squeezes the elastic sleeve 16 and compresses the second spring 20, so that the elastic sleeve 16 and the silicone ring 17 are deformed and no longer block the delivery pipe 19, so that the wastewater in the uppermost filter box 5 enters the filter box 5 below it and is filtered again, and then the wastewater is discharged into the wastewater treatment box 3 through the inner drain port 22 and the outer drain port 11 on the lower filter box 5.

[0037] If the wastewater has been filtered before entering the lower filter box 5, no filtered impurities will accumulate in the lower filter box 5, the weight of the lower filter box 5 will not increase, the lower filter box 5 will not move downward, the water pressure in the filter box 5 will not increase, and the wastewater will no longer enter the filter box 5 of the next level through the delivery pipe 19.

[0038] If the wastewater is not filtered cleanly before entering the lower filter box 5, filtered impurities will continue to accumulate in the lower filter box 5, and the weight of the lower filter box 5 will continue to increase. The lower filter box 5 will continue to move downward, causing the water pressure in the filter box 5 to continue to increase. Under the action of the water pressure, the elastic sleeve 16 and the silicone ring 17 will be deformed and will no longer block the delivery pipe 19, and the wastewater will enter the filter box 5 of the next level through the delivery pipe 19.

[0039] Example 3

[0040] like Figure 1-6 As shown, when other parts are the same as those of Example 2, the difference between this embodiment and Example 2 is that an activated carbon addition pipe 23 is provided on the left side of the filter box 5, the right end of the activated carbon addition pipe 23 is fixedly connected to the filter box 5, the activated carbon addition pipe 23 is connected to the inside of the filter box 5, and the left end of the activated carbon addition pipe 23 is threadedly connected with a sealing cap 24. Remove the sealing cap 24, and the activated carbon in the filter box 5 can be replaced through the activated carbon addition pipe 23.
