AI Technical Summary
The existing bathroom drainage pipe connections lack a secondary sealing structure, which makes it easy for odors or liquids to leak after a long period of use, affecting convenience.
The odor-proof toilet drain pipe consists of a pipe body and a connector. The connector has annular mounting grooves and sealing rings at both ends, and contains expansion seals and sealing plugs. Rubber material and water-absorbing resin are used to increase the sealing effect, and water vapor evaporation is achieved through air grooves and vents. Combined with the design of the odor-proof plug, the backflow of odors is reduced.
It achieves multiple sealing protections to prevent liquid leakage and odor leakage, improving ease of use and safety.
