Magnetic levitation floor drain core

Abstract

The invention provides a magnetic suspension floor drain core, which belongs to the technical field of floor drains. It solves the problem of poor reliability of the existing floor drain. The magnetic levitation floor drain core includes a cylindrical cylinder, a cylindrical inner shell connected to the cylinder, and a seal. The lower end of the cylinder is connected to a bracket. The seal includes a rod and a sealing part. The rod is passed through In the bracket, a reset mechanism is provided between the seal and the bracket, and the seal can abut the lower end of the inner shell and seal under the action of the reset mechanism. The middle part of the sealing part protrudes upward and forms an upper side of the sealing part. The drainage surface includes a curved surface or several inclined planes. The drainage surface of the sealing part also has several drainage grooves extending from the middle to the edge of the sealing part. The side walls of the drainage groove have an inclined or curved surface. A flow guide surface is provided, and the flow guide surface can receive the force of the water flow and cause the sealing member to rotate around the axis of the rod portion. The magnetic suspension floor drain core has the advantage of good reliability in use.

Description

technical field [0001] The invention belongs to the technical field of floor drains and relates to a magnetic suspension floor drain core. Background technique [0002] The floor drain is an important interface connecting the drainage system with the indoor ground. It is installed on the ground of various places such as kitchens, bathrooms and balconies. Although the floor drain is small in size, as 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. [0003] For this reason, people have designed a kind of self-sealing type floor drain and have applied for Chinese patent (its application number is: 200920314302.0; Its announcement number is: CN201554081U), this self-sealing type floor drain comprises the cylinder body that has water inlet and water outlet and is positioned at The panel above the cylinder, the water inlet of the cylinder communic...

Problems solved by technology

[0004] However, in the actual use of the floor drain, the water that needs to be discharged from the floor drain is often mixed with some small impurities, and the sealing plate used to seal the water outlet in the above-mentioned self-sealing floor drain is flat, which is very easy to make impurities remain. On the upper side of the sealing plate, it will lead to adhesion between the sealing plate and the cylinder or the inability to effectively seal due to the existence of impurities, and the reliability of the floor drain is poor.
