摘要： A connector, comprising: a housing which has a first port, a second port, and a first chamber in communication with the first port and the second port; a cover, which is connected to the housing and which has a second chamber in communication with the first chamber; and a bulging portion, which is disposed in the first chamber and protrudingly extends toward the second chamber. A side groove which obliquely curves and extends towards the second chamber is provided in the first chamber. The groove structure of the connector can guide a portion of fluid which is flowing into the first chamber from the first port towards the second chamber, so as to form a spiral upward vortex, thereby enlarging a flushing region, increasing the flushing efficiency, and reducing the risk of pollution.
