[0033] Further, the width of the primary filter tank 5 is greater than the width of the secondary filter tank 6, and the width of the secondary filter tank 6 is greater than the width of the tertiary filter tank 7;

[0034] The outer cap 1 is conical, the inner cap 2, the filter tube 3 and the water pipe 4 are all annular, and the outer cap 1, the inner cap 2, the filter tube 3 and the water pipe 4 are all arranged in concentric circles;

[0035] The bottom of the water pipe 4 is fixedly connected to the bottom plate 10, the bottom of the filter tube 3 and the inner cap 2 are fixedly connected to the top of the bottom plate 10, the top of the bottom plate 10 is fixedly connected with a connecting thread 11, and the bottom plate 10 is threadedly connected to the bottom of the outer cap 1 through the connecting thread 11.

[0036] By adopting the above technical scheme, when in use, the water cap is evenly placed and fixed at the bottom of the water filter tank, and then the sewage to be filtered is placed in the water filter tank. The sewage mixed with a large amount of impurities first enters the inner side of the outer cap 1 through the primary filter slot 5 of the outer cap 1, and then enters the inner side of the inner cap 2 through the secondary filter slot 6 of the inner cap 2, and then enters the inner side of the water pipe 4 through the tertiary filter slot 7 at the upper end of the filter tube 3 and the through slot 8 of the water pipe 4, and finally enters the guide pipe 12 through the water pipe 4 to complete the filtration of the sewage; the widths of the primary filter slot 5, the secondary filter slot 6 and the tertiary filter slot 7 decrease step by step, so that the primary filter slot 5, the secondary filter slot 6 and the tertiary filter slot 7 can filter impurities of different volumes, so that the impurities mixed with the sewage in the process of flowing into the water pipe 4 are gradually filtered out, so that the filtering effect of the water cap is better.

[0037] In this embodiment, the bottom plate 10 is circular, and the bottom plate 10 and the water pipe 4 are arranged concentrically; a circular through hole is provided in the middle of the water pipe 4, the through hole corresponds to the position of the water pipe 4, and the diameter of the through hole is the same as the inner diameter of the water pipe 4;

[0038] Between the filter tube 3 and the lower end of the water pipe 4 is a sedimentation tank 9, which is in a circular shape;

[0039] The middle of the bottom of the base plate 10 is fixedly connected to the guide pipe 12, and the guide pipe 12 is connected to the water pipe 4 through the through hole of the base plate 10; the outer side of the guide pipe 12 is provided with a fixing thread 13, and the guide pipe 12 is threadedly connected to the fixing bolt 14 through the fixing thread 13.

[0040] By adopting the above technical scheme, the widths of the primary filter tank 5, the secondary filter tank 6 and the tertiary filter tank 7 are gradually reduced, so that the closer the water is to the water pipe 4, the slower its flow rate, and the slower the flow rate of water is, the worse the driving force of impurities on impurities, so that impurities in the water can be precipitated.

In addition to being filtered by the multiple layers of filter tanks, impurities in the sewage can also precipitate by themselves, thereby further increasing the filtering effect of the water cap.

[0041] The working principle of the utility model is as follows: when in use, the water cap is evenly placed and fixed at the bottom of the water filter tank, and then the sewage to be filtered is placed in the water filter tank, and the sewage mixed with a large amount of impurities first enters the inner side of the outer cover cap 1 through the primary filter slot 5 of the outer cover cap 1, and then enters the inner side of the inner cover cap 2 through the secondary filter slot 6 of the inner cover cap 2, and then enters the inner side of the water pipe 4 through the tertiary filter slot 7 at the upper end of the filter tube 3 and the through slot 8 of the water pipe 4, and finally enters the guide pipe 12 through the water pipe 4 to complete the filtration of the sewage; the widths of the primary filter slot 5, the secondary filter slot 6 and the tertiary filter slot 7 are gradually reduced, so that the primary filter slot 5, the secondary filter slot 6 and the tertiary filter slot 7 can filter impurities of different volumes, so that the impurities mixed with the sewage in the process of flowing into the water pipe 4 are gradually filtered out, so that the filtering effect of the water cap is better;

[0042] The widths of the primary filter tank 5, the secondary filter tank 6 and the tertiary filter tank 7 decrease step by step, so that the closer the water is to the water pipe 4, the slower its flow rate. The slow-flowing water flow has a worse driving force on impurities, so that impurities in the water can be precipitated. Impurities are initially precipitated between the primary filter tank 5 and the secondary filter tank 6, and impurities are precipitated again between the secondary filter tank 6 and the tertiary filter tank 7. Finally, final precipitation is carried out in the precipitation tank 9. In addition to being filtered by the multiple layers of filter tanks, impurities in the sewage can also precipitate by themselves, thereby further increasing the filtering effect of the water cap.

[0043] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
