TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water drain, especially relates to a bounce water drain. BACKGROUND

[0002] In daily life, the water drain is an indispensable part in the water tank, washbasin and other drainage equipment, which plays an important role in controlling water flow discharge and preventing odor backflow. The traditional bounce water drain is usually composed of a water drain body, a bounce core and a sealing structure. However, the existing bounce water drain has some obvious defects.

[0003] On the one hand, the traditional bounce water drain has a deficiency in sealing performance. Due to the imperfect sealing design between the bounce core and the drain outlet, it is easy to cause sealing failure during long-term use, which can cause sewer odor backflow, indoor air pollution and affect people's living environment and quality of life. On the other hand, in order to realize the deodorization function, some bounce water drains need to keep the sealing state of the bounce core to the drain outlet for a long time. However, this long-term sealing will cause the bounce core to be frequently squeezed and rubbed, which can easily damage its parts and reduce the service life of the bounce water drain. Frequent replacement of the water drain not only increases the use cost, but also brings installation and maintenance troubles. SUMMARY
