A magnetic levitation floor drain core

Abstract

The invention provides a magnetic levitation floor drain core, belongs to the technical field of fixing construction, and aims to solve the technical problem of high failure possibility of the automatic sealing performance of the conventional floor drain. The magnetic levitation floor drain core comprises a core body and a sealing cover, wherein a water inlet is formed in the upper end of the core body; a water outlet is formed in the lower end of the core body; a magnet II is arranged in the sealing cover; a housing with a sealed inner chamber is fixed at the lower end of the core body; a magnet I is fixed in the inner chamber of the housing and below the magnet II; the sealing cover is arranged between the water outlet and the housing; the sealing cover is tightly clung to the water outlet under the action of the repulsive force between the magnet I and the magnet II, so as to be sealed. Through the adoption of the magnetic levitation floor drain core, the automatic sealing performance of the floor drain can be kept effective for a long time.

Description

technical field [0001] The invention belongs to the technical field of fixed buildings and relates to a magnetic suspension floor drain core. Background technique [0002] The floor drain is an important device connecting the drainage pipe system and the indoor floor, and is an important part of the drainage system in the residence. Its performance directly affects the quality of the indoor air, and is very important for the odor control in the bathroom. In order to achieve the purpose of deodorization and insect prevention, a sealing device is arranged in the existing floor drain, and the sealing device seals the floor drain after the drainage of the floor drain is completed, so as to achieve the purposes of deodorization and insect prevention. But this kind of floor drain cannot be automatically sealed, and often cannot play the purpose of automatic deodorization and insect protection when in use. The Chinese invention patent with the notification number CN103410213B disc...

AI Technical Summary

Problems solved by technology

The magnetic straight-through combined floor drain can reset the sealing cover in time after draining water, and realize an effective seal between the sealing cover and the lower outlet of the floor drain body. However, its disadvantage is that the inner magnetic strip is exposed in the installation hole , during the drainage process, the inner magnetic strip moves down with the guide rod, and the water may directly contact the inner magnetic strip. When there are fine metal impurities such as iron filings in the water, the fine metal impurities are easily absorbed by the inner magnetic strip. As more and more fine metals are absorbed at any time, the inner magnetic strip will become heavier, and the magnetic force of the inner magnetic strip will also weaken, resulting in weakened or even invalidated automatic sealing performance of the sealing cover
