[0051] The water-passing component 301 is arranged between the exhaust pipe A2 and the exhaust pipe B4; wherein the water-passing component 301 is positioned between the exhaust pipe A2 and the exhaust pipe B4 by the positioning component 302;

[0052] The water flow assembly 301 includes an inner cylinder 3011 and an outer cylinder 3012;

[0053] The upper and lower ends of the inner cylinder 3011 are in contact with and matched with the opposite sides of the two connection plates 5 respectively; the upper and lower ends of the outer cylinder 3012 are in contact with and matched with the opposite sides of the two connection plates 5 respectively; wherein the outer cylinder 3012 is sleeved on the inner cylinder 3011, and the upper and lower sides of the inner wall of the outer cylinder 3012 are respectively positioned and matched with the outer wall of the inner cylinder 3011 through three connecting rods 3013 arranged in a circular array; wherein a water inlet joint 3015 is fixedly provided at the bottom of the outer wall of the outer cylinder 3012, and the water inlet joint 3015 is connected to an external water inlet pipeline, and a water outlet joint 3014 is fixedly provided at the top of the outer wall of the outer cylinder 3012, and the water outlet joint 3014 is connected to an external water return pipeline;

[0054] The positioning assembly 302 includes a collar 3021, a fixing block B 3027, a fixing block A 3024, a double-headed screw 3026, a rotating handle 3028 and a positioning ring 3022;

[0055] The two sleeve rings 3021 are symmetrically sleeved on the upper and lower ends of the outer cylinder 3012; the two fixing blocks B3027 are respectively fixed on one side of the two sleeve rings 3021; ​​the fixing block A3024 is fixed in the middle of one side of the outer ring wall of the outer cylinder 3012; the double-headed screw 3026 is passed through the fixing block A3024; wherein the double-headed screw 3026 is rotatably connected with the fixing block A3024 through a bearing 3025; wherein the two threaded sections of the double-headed screw 3026 are respectively threadedly passed through the two fixing blocks B3027; the handle 3028 is fixed at the bottom end of the double-headed screw 3026; the two positioning rings 3022 are respectively fixed on the opposite sides of the two sleeve rings 3021; ​​wherein the insertion end of the positioning ring 3022 is plugged into and matched with the annular slot 501 opened on the inner side of the connecting plate 5.

During cleaning, the handle 3028 is rotated, and the double-headed screw 3026 rotates to drive the two sleeves 3021 to move relative to each other along the outer cylinder 3012 until the positioning ring 3022 leaves the annular slot 501, and moves out of the inner cylinder 3011 and the outer cylinder 3012 laterally, and the inner cylinder 3011 and the outer cylinder 3012 are cleaned from the outside; after the cleaning is completed, the inner cylinder 3011 and the outer cylinder 3012 are laterally put back between the exhaust pipe A2 and the exhaust pipe B4, and the handle 3028 is rotated in the opposite direction, and the double-headed screw 3026 rotates in the opposite direction to drive the two sleeves 3021 to move away from each other along the outer cylinder 3012 until the insertion end of the positioning ring 3022 is inserted into the annular slot 501, and the rubber ring 502 and the annular groove 3023 are plugged in, so as to realize the positioning of the inner cylinder 3011 and the outer cylinder 3012, and the inner cylinder 3011 and the outer cylinder 3012 can continue to be used.
