[0027] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , the present utility model provides an embodiment: a pipe joint assembly;

[0028] It includes an inner cylinder 3, a filtration cylinder 4 and a cleaning pipe 5. One side of the filtration cylinder 4 is movably connected to the inner cylinder 3, and the inner cylinder 3 is movably and detachably connected. The inner cylinder 3 is located inside the sleeve 1. A blocking ring 301 is connected to the outside of the inner cylinder 3. One end of the sleeve 1 is connected to the filtration cylinder 4. A first connection port 401 is formed through one side of the filtration cylinder 4, and the first connection port 401 is meshed and connected to the inner cylinder 3. A filter screen 402 is connected inside the filtration cylinder 4. A second connection port 403 is formed through the other side of the filtration cylinder 4. A cleaning pipe 5 is connected through the top of the filtration cylinder 4. A covering cap 501 is connected to the outside of the cleaning pipe 5, and the covering cap 501 is meshed and connected to the cleaning pipe 5. The inner cylinder 3 is detachably connected through the first connection port 401 or the second connection port 403, so that the inner cylinder 3 is located inside the sleeve 1. The inner cylinder 3 is in the shape of a circular ring cylinder. The outside of the inner cylinder 3 is used to connect an external flexible pipe.
