The quick-release connector cover 22 will drive the metal spring 24 to deform. As the position of the quick-release connector cover 22 changes, the limit of the steel ball 26 inside the speaker hole 25 will be reduced. At this time, the steel ball 26 can be displaced to a certain extent. At this time, the external water outlet pipe can be inserted into the inside of the second connector 21, and then the quick-release connector cover 22 is loosened. At this time, the metal spring 24 is reset, so that the quick-release connector cover 22 re-presses the steel ball 26 and cannot move, and the steel ball 26 presses the outer wall of the pipe. Due to the height adaptation between the first connector 1 and the quick-release connector assembly 2 or the universal connector assembly 3 and different ways of installing the pipe, the user can choose to install the pipe through the first connector 1, the universal connector assembly 3 or the quick-release connector assembly 2 according to their needs;
[0030] A check valve assembly 4 can be installed inside the second inner tank 12. When external water flows downward through the first connector 1, it will pass through the first water hole 45. At this time, the water will impact the anti-backflow circular plate 42, causing it to slide on the circular plate support column 43, and then pass through the second water hole 46. At this time, the water is in an open state, and water can pass normally. However, if the water flows back and first impacts the anti-backflow circular plate 42, the anti-backflow circular plate 42 will slide on the circular plate support column 43 until it blocks the entire second water hole 46. Then, the second water hole 46 is in a closed state. In this way, the connector has a backflow prevention function during use.
[0031] The entire check valve assembly 4 can also be replaced with a filter element 5. The columnar filter can filter out some impurities such as mud, sand, and gravel. In this way, the joint has a filtering function during use.
