Anti-odor well lid

Abstract

The utility model discloses an anti-odor well lid, which relates to the well lid technical field, and comprises a lid frame, the inner side of the lid frame is provided with an anti-odor mechanism, the anti-odor mechanism comprises a pipeline assembly and an active assembly, the pipeline assembly is used for intercepting part of liquid, the active assembly is used for actively preventing odor, and the pipeline assembly is used for blocking part of liquid. Through the arrangement of the anti-odor mechanism, after sewage enters the inner side of the pipeline assembly, part of liquid can be intercepted through a U-shaped structure, the intercepted liquid plays a role in sealing the coiled pipe to prevent odor, and meanwhile, a worker needs to start the driving assembly under the support of the coiled pipe and the frame plate; the driving assembly is used for promoting air in the cover frame to flow downwards into the drainage pipeline, so that the effect of preventing odor returning is achieved, and the air is prevented from being polluted by the odor returning.
