When the sealing element of the floor drain core is used, water flows into the diversion trench and impacts on the diversion surface of the side wall of the diversion trench, and the diversion surface is applied with acting force to drive the sealing element to rotate around the axis of the rod part. During this rotation, impurities in the water can move along the edge of the drainage surface facing the seal and be thrown out from the upper side of the seal under the centrifugal force of the seal rotation.
However, when water flows in from the upper end of the cylinder, only part of the water can enter the guide groove and is used for driving the sealing element to rotate, that is, the flowing water can only apply small acting force to the sealing element, and the sealing element can only rotate at a small rotating speed. And when the rotating speed of the sealing element is smaller, part of impurities with smaller mass, which are mixed in water conservancy, are easy to remain on the top surface of the sealing element.
