Problems solved by technology

[0005] 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.

Abstract

The invention provides a seal of a floor drain core, belonging to the floor drain technical field. It solves the problem of poor reliability of floor drain. The seal includes a rod-shaped rod portionand a seal portion fixed to the upper end of the rod portion, The upper side surface of the seal portion is formed with a drainage surface including a curved surface or a plurality of inclined planes,and the drainage surface of the seal portion is provided with a plurality of flow guide grooves extending from the middle portion to the edge of the seal portion, and the side walls of the flow guidegrooves are provided with a flow guide surface which is inclined or curved. The local leaky core seal has the advantage of good reliability in use.

Description

[0001] (This application is a divisional application based on the invention of 201611270023.X magnetic levitation floor drain core) technical field [0002] The invention belongs to the technical field of floor drains, and relates to a floor drain core and a sealing member of the floor drain core. Background technique [0003] 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. [0004] 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 drai...
