Description

Floating ball type floor drain

Technical Field

The utility model belongs to the field of floor drains, and particularly relates to a floating ball type floor drain.

Background

The floor drain is a communication port for connecting the drainage pipeline system with the indoor ground, a cover plate which is flush with the ground and is distributed with holes is arranged on the existing floor drain, and water on the ground flows into the drainage pipeline system through the cover plate and the floor drain, so that the influence of water stored on the ground on living and living of people is prevented.

Problems with existing floor drains: the floor drain can not prevent the reverse odor of the drainage system, and the floor drain generally has no non-return function, when the downstream of the drainage pipeline of a user is blocked, sewage in the drainage pipeline returns water to the user's home through the floor drain, so that furniture in the user's home is soaked, and peculiar smell in the returned water can be released in the user's home, thereby seriously affecting the living and living of the user.

Chinese patent (application publication No. CN108755914a, application publication No. 2018.11.06) discloses a split floating type large-flow anti-overflow drain, wherein the bottom of the floor drain cavity is provided with an anti-overflow device, the anti-overflow device comprises a sealing ball bracket cavity and an anti-overflow floating and anti-odor-resistant sealing ball, the bottom surface of the sealing ball bracket cavity is provided with a water outlet, the anti-overflow floating and anti-odor-resistant sealing ball is arranged in the sealing ball bracket cavity, and the anti-overflow floating and anti-odor-resistant sealing ball can be in sealing fit with the water outlet on the bottom surface of the sealing ball bracket cavity; the lower end of the sewage isolation sealing sleeve pipe extends into the cavity of the sealing ball bracket, and the anti-overflow floating deodorizing sealing ball can be in sealing fit with the lower end of the sewage isolation sealing sleeve pipe; in the above patent, by arranging the anti-overflow floating deodorization sealing ball at the bottom of the floor drain cavity, when the drain pipeline is blocked and water returns, the water level of the returned water in the sealing ball bracket cavity gradually rises, and the anti-overflow floating deodorization sealing ball in the sealing ball bracket cavity gradually floats along with the water level and is in sealing contact with the lower end of the dirt-isolation sealing sleeve, so that the returned water is prevented from flowing to the ground through the dirt-isolation sealing sleeve; however, the problem exists that as the anti-overflow floating deodorization sealing ball is arranged in the cavity of the sealing ball bracket, the passing area between the anti-overflow floating deodorization sealing ball and the cavity of the sealing ball bracket is smaller, so that the passing area of floor drain drainage is lower, the drainage efficiency is affected, and the use of a user is affected; meanwhile, due to the fact that the passing area of the position is small, when small-volume impurities fall into the cavity of the sealing ball bracket through the cover plate, accumulation is easy to occur between the anti-overflow floating deodorization sealing ball and the cavity of the sealing ball bracket, the cavity of the sealing ball bracket is blocked, or the anti-overflow floating deodorization sealing ball is clamped on the cavity of the sealing ball bracket, and therefore the anti-return water function cannot be achieved.

The present utility model has been made in view of this.
