Background
The drainer is commonly used in places such as a toilet, a kitchen and the like as a drainage device, is mostly arranged at the bottom of a basin or a water tank, has two functions of water storage and drainage, and has a drainage outlet which is mostly directly connected with the drainer.
Most of the existing drainers adopt pipeline connection to discharge sewage, a water inlet pipe and a water outlet pipe are connected by a straight-through type drainage pipe at a water outlet, and odor of the sewer pipe can escape from the drainer when the drainer is opened after long-time use, so that the surrounding environment is influenced. In order to solve the problem, some sewers in the market use a U-shaped or S-shaped pipeline connected between the bottom of the drainer and the sewer pipe, and use water at a bent part to achieve the purpose of sealing the sewer pipe, so that peculiar smell in the sewer pipe cannot escape to the outside of the drainer. However, the bent pipeline has small water storage capacity, and water sealed by the water seal is easy to dry, so that the deodorization function is poor. Especially for a sink in a kitchen, foreign matters such as residues and the like are more and easy to block a pipeline, so that the sink is slow to drain, troublesome to clean and inconvenient to live.
