Abrégé

The present invention relates to a urinal flushing and draining, sealing, and odor prevention method and device employing magnetic suspension, and resolves the issue of poor sealing performance in the prior art. A urinal body is flushed, drained, and sealed by means of a magnetic suspension flushing and draining valve sealingly sleeved on an upper inner necking of a gutter spout funnel. In the magnetic suspension flushing and draining valve, a top-opened gutter spout cage having an outer periphery of an upper end port is sealingly sleeved on the upper inner necking of the gutter spout funnel is used as a drainage channel. A slide rod having a sealing plate provided at an upper end vertically and slidably engages with a middle portion in the gutter spout cage by means of a vertical sliding engagement support frame, and serves as a spool capable of reciprocating vertically. An upper magnet and a lower magnet having the same polarity at opposite ends, and where vertical repulsion occurs, are respectively provided in a position at a lower end of the slide rod and in a corresponding position at the bottom of the gutter spout cage, and are used to provide an upward reset magnetic repulsion force to the slide rod and the sealing plate. A ring-shaped flange is provided at an upper portion of the gutter spout cage, and the ring-shaped flange and the sealing plate press against each other vertically to achieve sealing. When driven by pushing force resulting from flushing and draining, the sealing plate moves downwards, such that an opening to the drainage channel is formed between the sealing plate and the ring-shaped flange. An initial state is resumed after completion of the flushing and draining. The invention has good sealing performance, is reliable, facilitates water conservation and maintenance, and has a long service life.

Abrégé

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.

The present invention relates to a magnetic levitation-based draining and sealing method and device for a sink capable of odor isolation, for solving the problem of poor sealing performance in the prior art. A water drainage port of the sink discharges water downwards by means of a downward drainage pipe connected to a lower part; an inward-shrinking necking of the downward drainage pipe is sealedly fitted over a magnetic levitation flushing and draining valve for flushing, draining and sealing; the magnetic levitation flushing and draining valve uses an upper-opening water-falling cage of which the periphery of an upper port is sealedly fitted over the inward-shrinking necking of the downward drainage pipe as a downward drainage channel; a sliding rod having a sealing disc at an upper end 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 and used as a valve core reciprocating up and down; 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 to the sliding rod and the sealing disc; the upper part of the water-falling cage is provided with an annular flange plate sealed with the sealing disc in a vertical squeezing mode; under the impulsive force of flushing and draining, the sealing disc moves downwards, the downward drainage channel is opened by means of the sealing disc and the annular flange plate, and the initial state is restored after flushing and draining. The present invention has advantages of good flushing, draining and sealing performance and high reliability.
