Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to an anti-odor drainage floor drain. Background Art

[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. As an important component of the drainage system in a house, its performance directly affects the quality of indoor air and is very important for odor control in the bathroom.

[0003] The floor drains currently in use mainly use a gravity flap at the bottom to prevent odor backflow. When draining water, the water flow impacts the gravity flap to open it, and vice versa, the gravity flap blocks the outlet of the floor drain. However, when the gravity flap and the outlet of the floor drain are abutted, a gap will exist at the joint between the gravity flap and the outlet of the floor drain. Especially when impurities such as hair gather here, the gap will increase, causing the odor in the drainage pipe to overflow back into the room through the gap, resulting in a poor anti-odor effect.

[0004] An easily replaceable floor drain disclosed in application number CN202023176565.5 adopts the above-mentioned gravity flap structure to prevent odor backflow, but there is also the problem of poor odor backflow prevention effect. Utility Model Content
