Maglev emission closed odor isolation methodand device for sink

Abstract

The invention relates to a maglev emission closed odor isolation method and device for a sink. In order to solve the problem of poor sealing performance of the existing technology, a water outlet of the sink drains water down through a lower drainage pipe connected to the lower part, aninward-shrinking mouthof the lower drainage pipeand a magnetic suspension flushing valve are in sealed sleeving-fit with each other for flushing closure, the periphery of one upper port of the magnetic suspension flushing valveand an upper-opening water falling cage which is in sealed sleeving-fit with the inward-shrinking mouth of the lower drainage pipe are used as a lower drain channel, through a vertical sliding-fit support frame,the middle partin the waterfalling cage is equipped with a sliding rod with a closed disc at the upper endin a vertical sliding-fitmode, as a valve core with up and down reciprocating movement, the opposite positions of the lower end of the sliding rod and the bottom of the water fillingcage are respectively equipped with upper and lower homopolar magnets for providing upward reset magnetic repulsive force to the sliding rod and the closed disc, and the upper part of the water filling cage is provided with a ring type flange plate sealed with the closed disc in an up-down squeezing mode;under the impact of flushing force, the closed disc goes down, the lower channel is opened through the closed disc and the ring type flange plate, and the initial state is restored after flushing and flow-stopping. The maglev emission closed odor isolation method and device have the advantages ofgood flushingsealing performance and high reliability.

Description

technical field [0001] The invention relates to a washbasin, in particular to a method and device for magnetic suspension discharge sealing and odor isolation of the washbasin. Background technique [0002] With the improvement of people's awareness of the hazards of the sundries under the washbasin, it is extremely rare for the drain of the washbasin to be blocked. The main problem at present is that the drain under the washbasin is not well closed, and it is easy to return to odor. question. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, and provide a method for magnetic suspension discharge sealing and odor isolation of a washbasin with good flushing and sealing performance, and the present invention also relates to a device for realizing the method. [0004] In order to achieve the above-mentioned purpose, the magnetic levitation discharge and odor isolation method of the washbasin o...
