[0036] The interception structure 2 includes a connecting flange 201, a sealing gasket A 202, a water passage 203, a sealing gasket B 204 and an interception passage 205;

[0037] The connecting flange 201 is fixedly arranged at the water inlet port of the pump housing 1; the sealing gasket A202 is arranged at one side of the connecting flange 201; one side of the water passage 203 is in contact with the sealing gasket A202; the sealing gasket B204 is arranged at the other side of the water passage 203; one side of the intercepting channel 205 is in contact with the sealing gasket B204; wherein, the connecting flange 201, the sealing gasket A202, the water passage 203, the sealing gasket B204 and the intercepting channel 205 are fixedly connected by a plurality of screws 206 and nuts 207, the screw 206 passes through the intercepting channel 205, the sealing gasket B204, the water passage 203, the sealing gasket A202 and the connecting flange 201 in sequence, the nut 207 is threadedly installed at the end through which the screw 206 passes, and a filter screen 2053 is arranged on one side of the inner cavity of the intercepting channel 205, and the mesh size of the filter screen 2053 is selected and used by the technical personnel of this profession according to the actual situation.

[0038] The utility model has the advantages of filtering the water entering the pump casing 1 and removing impurities in the water by arranging the connecting flange 201, the sealing gasket A202, the water passage 203, the sealing gasket B204, the intercepting passage 205 and the filter screen 2053, thereby solving the problem that the water entering the water pump containing impurities will affect the height of the water discharged from the water pump outlet.

[0039] Specifically, an annular groove 2052 is opened on one side of the inner cavity of the intercepting channel 205, and the circular ring of the filter net 2053 is embedded in the annular groove 2052; wherein, the inner ring wall of the circular ring of the filter net 2053 is aligned with the inner cavity wall of the intercepting channel 205.

[0040] The utility model has the advantage of hiding the ring of the filter screen 2053 by setting the annular groove 2052, and not hindering the passage of water.

[0041] Furthermore, a baffle plate 2051 is fixedly provided on the other side of the inner cavity of the intercepting channel 205; wherein the baffle plate 2051 is configured to be in a circular bucket shape, and the baffle plate 2051 is inclined inwardly.
