Background

The floor drain is an important interface for connecting a drainage pipeline system and indoor ground, is used as an important part of a drainage system in a house, is widely applied to areas needing drainage, such as kitchens, bathrooms, balconies and the like, and is used for discharging sewage accumulated in the areas through the floor drain, and the drainage pipe inevitably becomes dirty after long-time use, so that bacteria are bred to pollute the indoor environment. Also, there is often some dirt that can drain with the water and reach the drain, accumulating over time causing clogging of the drain.

In the prior art, a filter screen is usually arranged in a floor drain to prevent dirt from entering a drain pipe as much as possible, or the floor drain is disassembled to clean the inside. But has the following disadvantages:

1. the drain pipe is deep and inconvenient to clean, the floor drain needs to be manually disassembled for cleaning, the drain pipe butted at the water outlet of the floor drain cannot be effectively cleaned, bacteria are easy to breed after long-term use, and the quality of indoor air is influenced;

2. even if a filter screen filters large dirt, part of sundries or waste can be discharged along with sewage, and the solid dirt can not be thoroughly discharged for a long time and can be continuously accumulated in a drain pipe until the blockage, so that the sewage can not be normally discharged.
