Novel structure of magnetic suspension floor drain core

Abstract

The invention discloses a novel structure of a magnetic suspension floor drain core. The novel structure comprises a core body and a sealing cover, the core body is internally provided with a drainagechannel, the bottom of the core body is connected with a shell through connecting arms, and the drainage channel is formed by gaps between the shell and the core body; a guide sleeve is arranged in the center of the shell, and the bottom of the guide sleeve is sealed by the shell; the sealing cover is downwards provided with a guide pillar, and the guide pillar is slidably and cooperatively connected with the guide sleeve; a magnetic restoration structure is arranged between the guide pillar and the shell, and the guide pillar generates upward-pushing restoration force under the effect of themagnetic restoration structure to make the sealing cover block a water outlet of the drainage channel. According to the novel structure, the bottom of the guide sleeve is completely sealed, the contact of a magnet on the guide pillar and the outside is isolated fundamentally, the occurrence of the phenomena of attracting magnetic impurities is avoided, and normal restoration of the guide pillar is guaranteed; meanwhile, a conical bevel is arranged on the upper end face of the shell to avoid the situation that the upper end face of the shell and the inner side face of the sealing cover fit andattract each other, and it is guaranteed that the floor drain core has effective deodorization and insect prevention functions.

Description

technical field [0001] The invention relates to a floor drain core, in particular to a novel structure of a magnetic suspension floor drain core. Background technique [0002] Patent CN104863246B discloses a magnetic levitation floor drain core, the main purpose of which is to isolate the outer magnet, that is, the contact problem between the magnet one and water. [0003] In the above structure, the guide rod is set in a guide sleeve that penetrates up and down, and the bottom of the guide sleeve directly communicates with the outside world. When the guide rod slides to the limit position during the drainage process, the guide rod slides to the bottom of the guide sleeve. The magnet three is easy to absorb the magnetic impurities from the outside. As a result, the gravity of the guide rod will increase and affect the reset. [0004] In addition, the shell used in the above structure is spherical, and the outer surface of the shell can fit the inner surface of the sealing c...

Problems solved by technology

However, in actual use, it is found that water will inevitably enter the mating surface formed by the outer surface of the housing and the inner surface of the sealing cover during the drainage process, and the water itself has a strong surface tension. When the side surface is attached to the outer surface of the shell, the sealing cover of the column will be tightly adsorbed due to the effect of water surface tension. As a result, the sealing cover will not be able to rise and reset normally after the drainage is completed, resulting in the failure of the anti-odor and anti-insect effects
