Abstract: The present invention relates to a magnetic levitation-based downward discharging, sealing, and deodorizing method and device for a floor drain, for solving the problem in the prior art of poor sealing performance. Upper and lower annular bosses of a drain hole of a floor drain end plate are respectively equipped with an upper coarse drain plate and a lower fine drain plate. A port of a bottom annular boss of a bottom plate of the drain hole of the floor drain end plate is sealably sleeved with a magnetic levitation flushing and discharging valve located below the lower fine drain plate. The magnetic levitation flushing and discharging valve uses a top-open water-falling cage of which the periphery of an upper port is sealably sleeved on the port of the bottom annular boss as a downward discharging channel. A sliding rod having an upper end provided with a sealing disc is provided in the middle part in the water-falling cage in a vertical sliding-fit mode by means of a vertical sliding-fit support frame. The opposite positions of the lower end of the sliding rod and the bottom of the water-falling cage are respectively provided with upper and lower homopolar magnets for providing magnetic repelling power for upward resetting. The upper part of the water-falling cage is provided with an annular flange sealed with the sealing disc in a vertical squeezing mode. Under the impulsive force of flushing and discharging, the sealing disc moves downwards, the downward discharging channel between the sealing disc and the annular flange is opened, and after flushing, discharging and flow-stopping, the sealing disc restores, under the action of the magnetic repelling power, an initial state in which the sealing disc is sealed with the annular flange in a vertical squeezing mode. The present invention has the advantages of good sealing performance and easy maintenance.
