The extraction seat 401 and the sampling port 415 are fixedly connected to the bottom end of the sampling seat 2. The inner wall of the extraction seat 401 is slidably connected to a partition 402. The outer wall of the partition 402 is provided with a sealing ring 403. The bottom end of the partition 402 is fixedly connected to a first threaded rod 404 extending below the extraction seat 401. The bottom end of the extraction seat 401 is located on the outer wall of the first threaded rod 404 and is rotatably connected to a rotating shaft. Ring 405, the rotating ring 405 is threadedly connected to the first threaded rod 404, the bottom end of the inner wall of the sampling seat 2 is fixedly connected to the mounting seat 406, the interior of the sampling seat 2 is located on one side of the extraction seat 401 and is slidably connected to a baffle 407, the bottom end of the sampling seat 2 is located below the mounting seat 406 and is rotatably connected to a rotating block 412, the top of the rotating block 412 is fixedly connected to a connecting shaft 411, and the top of the connecting shaft 411 is fixedly connected to a second bevel gear 410, The interior of the mounting seat 406 is located on the outer wall of the second bevel gear 410 and is rotatably connected to the first bevel gear 409.

[0031] In this embodiment: when the disinfectant is sampled through the sampling seat 2, the sampling tank 3 is first installed on the sampling port 415, and then the rotating ring 405 is rotated. The rotating ring 405 rotates to drive the first threaded rod 404 to move. The displacement of the first threaded rod 404 drives the partition 402 to slide in the extraction seat 401. The partition 402 slides downward to allow the disinfectant in the pipeline to enter the extraction seat 401. When a certain amount of disinfectant enters, the rotating block 412 is rotated. The rotating block 412 rotates to drive the connecting shaft 411 to rotate. The connecting shaft 411 rotates to drive the second bevel gear 410 to rotate. The second bevel gear 410 rotates to drive the first bevel gear 409 to rotate. The first bevel gear 409 rotates to drive the second threaded rod 408 to rotate. The second threaded rod 408 rotates The movement drives the baffle 407 to move, and the baffle 407 is moved and inserted into the slot 413, closing the top of the extraction seat 401. At the same time, the baffle 407 enters the slot 413 and contacts the extrusion block 416, pushing the extrusion block 416 to move, causing the first spring 417 to be squeezed. The displacement of the extrusion block 416 drives the vertical plate 418 to move, and the displacement of the vertical plate 418 causes the through hole 419 to move into the connecting groove 414, canceling the closure of the connecting groove 414 by the vertical plate 418; at this time, the rotating ring 405 can be rotated to drive the partition 402 to move upward, and the disinfectant between the partition 402 and the baffle 407 flows into the sampling port 415 through the discharge trough 420 and the connecting groove 414, and then enters the sampling tank 3 through the sampling port 415 for sampling.

[0032] It should be noted that the amount of sampled liquid is controlled by adjusting the height of the baffle 402. For easier observation, a transparent observation window with scale can be provided on the sidewall of the extraction seat 401. The discharge chute 420 is L-shaped. When the baffle 407 enters the slot 413, one end of the discharge chute 420 communicates with the interior of the extraction seat 401, and the other end communicates with the connection slot 414.

[0033] After the sampling is completed, the rotating block 412 is rotated to drive the baffle 407 to reset. When the baffle 407 moves out of the slot 413, the squeezing block 416 is reset by the elastic force of the first spring 417, driving the vertical plate 418 to reset and close the connecting slot 414. Then, the rotating ring 405 is rotated to drive the partition 402 to move and reset.

[0034] Please refer to Figures 5 to 8The connecting mechanism 5 includes a fixed groove 501, which is opened on the inner wall of the sampling tank 3. The interior of the sampling port 415 is slidably connected to a fixed block 502 extending from the sampling port 415. A second spring 503 is connected between the fixed block 502 and the sampling port 415. The interior of the sampling seat 2 is slidably connected to a push frame 504 that passes through the fixed block 502. The top of the push frame 504 is fixedly connected to a displacement plate 505. The interior of the sampling seat 2 is rotatably connected to a third threaded rod 506 that passes through the displacement plate 505. The bottom end of the third threaded rod 506 is fixedly connected to a rotating column 507. The extraction seat 401 The interior of the extraction seat 401 is slidably connected to an extrusion frame 508 extending to one side of the sampling port 415, the interior of the extraction seat 401 is located on the outer wall of the extrusion frame 508 and is rotatably connected to a spur gear 509, the interior of the extraction seat 401 is located on the outer wall of the spur gear 509 and is slidably connected to a movable frame 510, a third spring 511 is connected between the movable frame 510 and the extraction seat 401, the bottom end of the movable frame 510 extends to the bottom of the extraction seat 401 and is fixedly connected to a displacement ring 512, the top end of the displacement ring 512 is evenly distributed with first docking blocks 513, and the bottom end of the rotating ring 405 is evenly distributed with second docking blocks 514.

[0035] In this embodiment, when installing the sampling tank 3, the sampling tank 3 is sleeved on the outer wall of the sampling port 415, and the fixing block 502 is engaged into the fixing groove 501 by the elastic force of the second spring 503 to fix the sampling tank 3. When removing the sampling tank 3, the rotating column 507 is rotated, and the rotating column 507 rotates to drive the third threaded rod 506 to rotate, and the third threaded rod 506 rotates to drive the displacement plate 505 to move, and the displacement of the displacement plate 505 drives the pushing frame 504 to move, and the displacement of the pushing frame 504 pushes the fixing block 502 out of the fixing groove 501, so that the fixation of the sampling tank 3 can be cancelled.

[0036] When the sampling tank 3 is not installed on the outer wall of the sampling port 415, the first docking block 513 and the second docking block 514 engage, thereby fixing the rotating ring 405 and preventing sampling when the sampling tank 3 is not installed, which would cause waste. When the sampling tank 3 is installed, the sampling tank 3 is sleeved on the outer wall of the sampling port 415, and the sampling tank 3 moves and contacts the extrusion frame 508, pushing the extrusion frame 508 to move.

At the same time, the baffle 407 enters the slot 413 and contacts the extrusion block 416, pushing the extrusion block 416 to displace, causing the first spring 417 to be squeezed. The displacement of the extrusion block 416 drives the vertical plate 418 to displace. The displacement of the vertical plate 418 causes the through hole 419 to move into the connecting groove 414, canceling the closure of the connecting groove 414 by the vertical plate 418.
