The plurality of flow channel water inlets 61 are arranged at intervals, so that when the motor 2 shaft 21 drives the impeller 7 to rotate, the water entering the pump chamber 6 rotates with the impeller 7 and is discharged to the drain 9 from different flow channel water inlets 61 respectively, to avoid concentrated discharge from one flow channel water inlet 61. Preferably, each flow channel water inlet 61 is tangent to the side wall of the pump chamber 6. When the water flows along the rotating path formed by the rotation of the impeller, the setting position of the flow channel water inlet 61 can adapt to the flow trajectory of the water flow and ensure the flow rate of the water flow; corresponding to each flow channel water inlet 61, a water flow channel 62 is formed in the pump housing 1 around the outer periphery of the pump chamber 6, and the water flow channel 62 is spiral and leads to the drain 9; the focus here is on Figure 6 In this specific embodiment, there are two flow channel water inlets 61, which are arranged opposite to each other, one of which is close to the drain port 9, so that part of the water flows out quickly, and the other flow channel water inlet 61 is far away from the drain port 9, and the water flow channel 62 where it is located forms a turbine-shaped guide channel, so that a beam of water with a high flow rate is formed in the guide channel to accelerate the discharge of water. Of course, in other embodiments, the flow channel water inlet 61 can also be three, four or more, not limited to this, and those skilled in the art can design it according to specific circumstances.

[0045] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
