Abstract

A closestool for preventing a sewage pipeline from returning odor comprises a closestool body, an odor isolation module and a sewage pump which are mutually connected; the odor isolation module comprises a shell and a sealing assembly arranged in the shell, and the sealing assembly divides the shell into a sewage inlet side and a sewage discharge side; the sealing assembly is actuated to open by negative pressure generated by a sewage pump located at a sewage side to communicate with a sewage passage between the sewage outlet and the sewage pump, and is reset to a position closing the sewage passage by an elastic member when the negative pressure disappears. By creating a negative pressure on the trapway side, the seal assembly opens the trapway and resets the sliding seal to a position closing the trapway via the resilient member. Because the closestool does not need water seal, the odor backflow caused by the reduction of the height of the water seal due to the fact that the closestool is not used for a long time is overcome, the uncomfortable feeling of splashing of liquid caused by the fact that excrement falls into the water seal is avoided, meanwhile, a trap used for storing the water seal is not needed, and the porcelain burning process difficulty of the closestool is reduced.
