Description

Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to a double anti-odor and anti-backflow floor drain. Background Art

[0002] A floor drain refers to a drainage appliance connecting the ground and a drainage pipe system, and is an important interface connecting the drainage pipe system and the indoor ground. As an important component of the drainage system in a residence, its performance directly affects the quality of indoor air and is very important for controlling the peculiar smell in the bathroom.

[0003] Floor drains are often installed in places with a lot of water use such as bathrooms and balconies. In addition to water leakage at home, the most annoying thing is the return of odors, so the floor drain becomes particularly important. In real life, people often report that the floor drain will return odors, making the room stink. Not to mention the return of odors, the drainage speed is very slow, and the phenomenon of water accumulation around often occurs; especially for low-floor users, they sometimes encounter blockages in the pre-buried downpipes on the floor, resulting in the phenomenon of sewage flowing back from the floor drain into the house, causing environmental pollution at home, and property losses such as soaking of walls, floors and furniture. For this reason, we propose a double anti-odor and anti-backflow floor drain. Content of the Utility Model
