When the first pipe 1 and the second pipe 2 have been installed, the connecting pipe 3 can still be removed between the first pipe 1 and the second pipe 2, which is convenient for disassembly, can meet market demand, and is suitable for promotion. When using the utility model, if the connecting pipe 3 needs to be disassembled after the first pipe 1 and the second pipe 2 have been installed, the internal threaded pipe 4 is rotated forward to move the two internal threaded pipes 4 in a direction close to each other. The internal threaded pipe 4 drives the slider 5 to slide in the corresponding first annular groove 6 until the internal threaded pipe 4 is no longer threadedly connected to the first pipe 1 and the second pipe 2. At this time, the connecting pipe 3 can be removed between the first pipe 1 and the second pipe 2, so as to facilitate cleaning of the inner walls of the first pipe 1, the second pipe 2 and the connecting pipe 3; when installing the connecting pipe 3, place the connecting pipe 3 between the first pipe 1 and the second pipe 2 so that the two ends of the connecting pipe 3 are connected to the first pipe in turn.

The filter 21 can filter the exhausted gas to avoid clogging the pipe; the two ends of the connecting pipe 3 are sequentially abutted against the first pipe 1 and the second pipe 2, so that the two filter screens 21 are limited, so that the filter screens 21 are located in the corresponding fourth annular groove 20.

[0018] Specifically, as shown in the figure, the connecting pipe 3 described in the present embodiment is divided into a first connecting pipe 30 and a second connecting pipe 31. The first connecting pipe 30 and the second connecting pipe 31 are exactly the same and are symmetrically distributed. After the installation is completed, one end of the first connecting pipe 30 and the second connecting pipe 31 are respectively in contact with the filter screens 21 in the first pipe 1 and the second pipe 2, and the ends of the first connecting pipe 30 and the second connecting pipe 31 close to each other are in contact with each other. The first annular groove 6 is successively opened at the ends of the first connecting pipe 30 and the second connecting pipe 31 far away from each other, the inner periphery of the second connecting pipe 31 is fixedly connected to one end of the inner pipe 38, the inner periphery of the second connecting pipe 31 is fixedly connected to the outer periphery of one end of the inner pipe 38, the inner periphery of the first connecting pipe 30 is in airtight sliding contact with the outer periphery of the inner pipe 38, and the other end of the inner pipe 38 is provided with a second annular groove 32, and the outer periphery of the second annular groove 32 is far away from the second One end of the connecting pipe 31 is communicated with the outside world respectively, a circular ring 33 is fixedly installed on the inner circumference of the first connecting pipe 30, and the outer circumference of the circular ring 33 is fixedly connected to the inner circumference of the first connecting pipe 30, the circular ring 33 is located in the second annular groove 32, the inner circumference of the second annular groove 32 is provided with a thread, and an internal threaded ring 34 is installed with the thread, and a plurality of L-shaped rods 35 are fixedly installed on the internal threaded ring 34, and a strip slide groove 36 is provided on the inner circumference of the first connecting pipe 30 corresponding to the L-shaped rod 35, and the L-shaped rod 35 is slidably installed in the strip slide groove 36 respectively, and the L-shaped rod 35 can slide left and right along the strip slide groove 36, and a second annular sealing gasket 37 is provided between the internal threaded ring 34 and the circular ring 33, and the inner circumference of the second annular sealing gasket 37 is gap-matched with the inner circumference of the second annular groove 36, and the first connecting pipe 30, the second connecting pipe 31, the second annular groove 32, the circular ring 33, the internal threaded ring 34 and the second annular sealing gasket 37 are coaxially arranged. The second connecting pipe 31 is screwed forward, and the second connecting pipe 31 drives the inner pipe 38 to rotate. Since the outer peripheral thread of the second annular groove 32 on the inner pipe 38 cooperates with the installation of the inner thread ring 34, and the L-shaped rod 35 is slidably installed in the strip slide groove 36, the inner thread ring 34 moves to the right, and the inner thread ring 34 moves to the right and squeezes the second annular sealing gasket 37 together with the circular ring 33, so that the second annular sealing gasket 37 expands to seal the gap between the first connecting pipe 30 and the inner pipe 38; when the first pipe 1 and the second pipe 2 that have been installed are connected, When the distance between the first connecting tube 30 and the second connecting tube 31 is greater than the length of the connecting tube 3, the second connecting tube 31 moves to the right, and the second connecting tube 31 moves to the right, driving the inner tube 38 and the internal threaded ring 34 to move to the right.
