[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1 - Figure 6 A sewage pump which is easy to clean comprises a pump body 1 and a connecting ring 2 installed at the water inlet end of the pump body 1, the connecting ring 2 is connected to a mounting ring 3 on the side away from the pump body 1, the mounting ring 3 is connected to a filter screen cover on the side away from the pump body 1, the filter screen cover comprises an annular bottom plate 4, an annular filter screen 5 and a top plate 6, one side of the annular bottom plate 4 is connected to the side of the mounting ring 3 away from the connecting ring 2, and the other side is fixedly connected to the annular filter screen 5, and one end of the annular filter screen 5 away from the annular bottom plate 4 is fixedly connected to the top plate 6.

[0024] like Figure 1 - Figure 6 As shown, the utility model is similar to the existing sewage pump structure that is easy to clean, such as the sewage pump that is easy to clean disclosed in the patent with announcement number CN214221511U. The main improvement of the utility model is that it can reduce the blockage of the sewage pump water inlet end, and it is convenient to disassemble and clean the filter cover, such as Figures 1 to 6 As shown, when the sewage pump which is easy to clean in the utility model is in use, the mounting ring 3 is mounted on the connecting ring 2 on the pump body 1, and then the annular bottom plate 4 of the filter screen cover is connected to the mounting ring 3. When the sewage flows to the water inlet of the sewage pump, it will first be filtered through the annular filter screen 5, and larger impurities will be blocked on the outside of the annular filter screen 5, thereby reducing the blockage of the pump body 1 and ensuring the normal operation of the pump body 1. At the same time, when there are many impurities on the outside of the annular filter screen 5, the filter screen cover can be removed from the mounting ring 3, so as to facilitate the cleaning of the outside of the annular filter screen 5.

[0025] like Figure 1 - Figure 6As shown, the connection ring 2 is fixedly connected to the mounting ring 3 by a plurality of bolts. The connection ring 2 is similar to existing sewage pumps or water pumps, such as the sewage pump of model QW50, which is basically provided with screw holes, and the connection ring 2 is connected to the mounting ring 3 by bolts, which can be applicable to the connection and installation of most sewage pumps, thereby improving the applicability of the installation structure.

[0026] like Figure 2 - Figure 6 As shown, a through hole 601 is formed on one side of the top plate 6 away from the annular filter screen 5, and a circular filter screen 7 is fixedly connected to the inner wall of the through hole 601. When the annular filter screen 5 is used to filter impurities in sewage, the circular filter screen 7 on the top plate 6 can also be used for filtering, thereby further increasing the filterable area of ​​the filter screen cover and improving the filtering efficiency.

[0027] like Figure 6 As shown, a plurality of reinforcing rods 8 are fixedly connected to the inner wall of the through hole 601, and the plurality of reinforcing rods 8 are all located on the side of the circular filter screen 7 close to the pump body 1, and the plurality of reinforcing rods 8 are cross-arranged. When sewage carries a large amount of impurities and flows through the circular filter screen 7, the impurities accumulate on the circular filter screen 7, and when the circular filter screen 7 is squeezed, the reinforcing rods 8 can support the circular filter screen 7, thereby improving the firmness of the circular filter screen 7 and reducing the damage rate of the circular filter screen 7.

[0028] like Figure 5 and Figure 6 As shown, the inner wall of the annular filter 5 is fixedly connected with a plurality of support rods 9, and both ends of the plurality of support rods 9 are respectively fixedly connected with the top plate 6 and the annular bottom plate 4. The top plate 6 and the annular bottom plate 4 can be fixed in relative position by the plurality of support rods 9, thereby increasing the supporting force of the top plate 6 and the annular bottom plate 4, and preventing the annular filter 5 from bending. At the same time, when a large amount of impurities are accumulated on the outside of the annular filter 5, the plurality of support rods 9 can also support the annular filter 5, thereby preventing the annular filter 5 from being squeezed and damaged, and improving the connection firmness of the overall filter cover.

[0029] like Figure 1 - Figure 6 As shown, the side of the mounting ring 3 close to the annular bottom plate 4 is provided with a plurality of L-shaped card slots 301, and the plurality of L-shaped card slots 301 are symmetrical along the outer edge of the side of the mounting ring 3 close to the annular bottom plate 4, and the side of the annular bottom plate 4 close to the mounting ring 3 is fixedly connected with a plurality of L-shaped card blocks 10 matching the plurality of L-shaped card slots 301, and the plurality of L-shaped card blocks 10 are respectively slidably connected with the plurality of L-shaped card slots 301. When a large amount of impurities are accumulated on the outside of the filter screen cover, gradually affecting the sewage flowing into the water inlet on the pump body 1, the entire filter screen cover can be rotated to one side, so that the L-shaped card blocks 10 slide and separate from the L-shaped card slots 301, thereby smoothly removing the filter screen cover from the mounting ring 3, facilitating the cleaning of the filter screen cover and maintaining the filtering effect of the filter screen cover.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
