[0003] At present, the floor drain core structure is mainly a magnetic flip cover floor drain core. This kind of floor drain core uses the adsorption of a magnet to flip and seal the cover. This kind of floor drain core may fail after the magnetic force weakens. During daily use in a user's home, iron filings and various impurities may be adsorbed from the sewage, causing the cover to be unable to completely close due to the attachment of impurities, thereby reducing the sealing performance and causing failure.

At this time, the second end 172” of the drive unit contacts the lower elastic end 161, and the lower elastic end 161 interferes with the rotation of the drive unit around the axis of rotation, so that the flip cover 12 remains in the first position. After enough water accumulates in the water passage 111, the accumulated water will press the flip cover 12 to rotate around the axis of rotation, and the second end 172” of the drive unit will overcome the elastic force of the elastic member 16 and lift the lower elastic end 161 until the flip cover 12 is in the second position. If the water accumulation in the water passage 111 decreases and is insufficient to overcome the elastic force of the elastic member 16, the elastic member 16 will drive the second end 172” of the drive unit to rotate in the opposite direction, so that the flip cover 12 returns to the first position.
