Floor drain and floor-drain rubber check valve

Abstract

The invention discloses a floor drain and a floor-drain rubber check valve, wherein the floor-drain rubber check valve comprises a mounting part and a water outlet part; the mounting part of the floor-drain rubber check valve is cylindrical, a bent pipe is included between the mounting part and the water outlet part, and the mounting part of the floor-drain rubber check valve is connected with thewater outlet part of a floor-drain shell. In the invention, as the bent floor-drain rubber check valve is adopted, the water outlet part of the floor-drain rubber check valve enters into a transversepipe of the floor drain while in mounting to form same-layer drainage, thereby greatly reducing the height of the floor drain. The floor drain does not need to pass through floors, therefore, not only the leakage caused by perforating can be avoided, but also the bent pipe without the floor drain on a downstair ceiling provides the convenience for downstair maintenance. The floor-drain rubber check valve can play roles of household environment-protection, health protection, mosquito prevention, bacteria-breeding prevention, odor-refluxing prevention and plugging prevention.

Description

[technical field] [0001] The invention relates to a drainage device in a building, in particular to a floor drain and a rubber check valve for the floor drain. [Background technique] [0002] There are two major disadvantages of traditional floor drains. One is that the floor drain is high and needs to pass through the floor. This kind of floor drain is not only inconvenient to maintain and clear, but also easily causes leakage because it passes through the floor. At the same time, it brings difficulties to the decoration downstairs. The traditional rubber floor drain Due to the large length of the check valve, the height of the floor drain cannot be reduced. The floor drain is not designed with a sewage screen, and it is easy to block. The second is to use a water seal to block the odor in the drain pipe. The pressure resistance is low, and the effect of blocking the odor is not ideal, and it is easy to breed mosquitoes, bacteria, cockroaches and other pests. Greatly red...

Problems solved by technology

One is that the floor drain is high and needs to pass through the floor. This kind of floor drain is not only inconvenient to maintain and clear, but also easily causes leakage because it passes through the floor. At the same time, it brings difficulties to the decoration downstairs. The traditional rubber floor drain The height of the floor drain cannot be lowered due to the length of the check valve

The floor drain is not designed with a sewage screen, and it is easy to block

The second is to use water seal to block the odor in the drain pipe, the pressure resistance is low, the effect of blocking the odor is not ideal, and it is easy to breed mosquitoes, bacteria, cockroaches and other pests

Greatly reduce the environmental quality and health protection of the home
