[0030] Reference Figure 2 and Figure 3 As shown, in this embodiment: the limiting mechanism includes an insertion rod 8 installed on the left side of the toggle plate 6, an insertion groove 9 is opened on the left side of the sliding groove 5, and an opening 10 is opened on the surface of the sliding groove 5. When the staff needs to adjust the airflow of the exhausted smoke, the adjustment plate 4 is moved to a suitable position, the toggle plate 6 is pushed to the left to insert the insertion rod 8 into the opening 10, so that the adjustment plate 4 is limited, and then the clamping plate 7 is moved downward to clamp the toggle plate 6, so that the toggle plate 6 is limited, thereby achieving airflow adjustment of the exhausted smoke.

[0031] Reference Figure 3 As shown, in the present embodiment: the surface of the insertion rod 8 is slidably connected with an elastic spring 11, the end of the elastic spring 11 close to the toggle plate 6 is fixedly connected to the toggle plate 6, and the end of the elastic spring 11 away from the toggle plate 6 is fixedly connected to the inside of the sliding groove 5. Through the setting of the elastic spring 11, when the staff needs to adjust the position of the adjustment plate 4 again, the clamping plate 7 is moved upward to release the limit of the toggle plate 6. At this time, the elastic force stored in the elastic spring 11 is released, so that the elastic spring 11 drives the toggle plate 6 to rebound quickly, releasing the limit on the adjustment plate 4, thereby achieving the rapid release of the limit when the adjustment plate 4 needs to be adjusted.

[0032] Reference Figure 3 As shown, in this embodiment: the front end and the rear end inside the sliding groove 5 are both provided with a first sliding groove 12, the front end and the rear end of the toggle plate 6 are both fixedly connected with a first sliding block 13, the interior of the first sliding groove 12 is slidably connected to the first sliding block 13, and the setting of the first sliding groove 12 and the first sliding block 13 can make the toggle plate 6 move more stably inside the sliding groove 5, preventing the insertion rod 8 from being unable to be inserted into the opening 10 due to deviation.

[0033] Reference Figure 4 and Figure 5 As shown, in this embodiment: a second slide groove 14 is opened at the top and bottom ends inside the processing chamber 2, and a second slider 15 is fixedly connected to the top and bottom ends of the adjustment plate 4. The interior of the second slide groove 14 is slidably connected to the second slider 15. Through the arrangement of the second slide groove 14 and the second slider 15, the adjustment plate 4 can form a stable limit when moving inside the sliding opening 3, thereby improving the adjustment efficiency of the adjustment plate 4.

[0034] Reference Figure 6 and Figure 7As shown, in this embodiment: the pulling mechanism includes a pulling groove 16 opened at the top of the conveying pipe 1, a pulling plate 17 is slidably connected inside the pulling groove 16, a fixing plate 18 is fixedly connected to the bottom end of the pulling plate 17, an exhaust fan 19 is installed on the top of the fixing plate 18, a first connecting plate 20 is fixedly connected to the top of the conveying pipe 1, a threaded rod 21 is rotatably connected inside the first connecting plate 20, a rotating plate 22 is fixedly connected to the rear end of the threaded rod 21, a second connecting plate 23 is fixedly connected to the top of the pulling plate 17, and a second connecting plate 24 is fixedly connected to the top of the pulling plate 17. A limiting groove 24 is provided on the surface of the connecting plate 23. When there is too much dust on the exhaust fan 19 and it needs to be cleaned, the rotating plate 22 is rotated outward to drive the threaded rod 21 to rotate out, so that the pull-out plate 17 is released from the limit, and then the pull-out plate 17 is pulled upward to pull out the exhaust fan 19. At this time, the exhaust fan 19 is cleaned. After completion, the pull-out plate 17 is put back to reset the exhaust fan 19, and then the rotating plate 22 is rotated inward to make the threaded rod 21 rotate into the limiting groove 24, so that the pull-out plate 17 is limited, thereby achieving convenient cleaning of the exhaust fan 19.

[0035] Reference Figure 7 As shown, in the present embodiment: third slide grooves 25 are provided on both sides of the pull-out groove 16, third sliders 26 are fixedly connected on both sides of the pull-out plate 17, and the interior of the third slide groove 25 is slidably connected to the third slider 26. Through the arrangement of the third slide groove 25 and the third slider 26, the pull-out plate 17 is more stable during the process of pulling out and putting back, thereby improving the cleaning efficiency of the exhaust fan 19.

[0036] The practical working principle of the present invention is as follows: when the staff needs to adjust the airflow of the exhaust smoke, when the adjusting plate 4 is moved to the appropriate position, the toggle plate 6 is pushed to the left to insert the insertion rod 8 into the opening 10, so that the adjusting plate 4 is limited, and then the clamping plate 7 is moved downward to clamp the toggle plate 6, so that the toggle plate 6 is limited, thereby achieving the airflow adjustment of the exhaust smoke. Through the setting of the elastic spring 11, when the staff needs to adjust the position of the adjusting plate 4 again, the clamping plate 7 is moved upward to release the limit of the toggle plate 6. At this time, the elastic force stored in the elastic spring 11 is released, so that the elastic spring 11 drives the toggle plate 6 to rebound quickly, and the limit of the adjusting plate 4 is released, thereby achieving the rapid release of the limit when the adjusting plate 4 needs to be adjusted. Through the setting of the first sliding groove 12 and the first sliding block 13, the toggle plate 6 can move more stably in the sliding groove 5 to prevent The present offset causes the insertion rod 8 to be unable to be inserted into the opening 10. By setting the second slide groove 14 and the second slider 15, the adjustment plate 4 can be firmly limited when moving inside the sliding opening 3, thereby improving the adjustment efficiency of the adjustment plate 4. When there is too much dust on the exhaust fan 19 and it needs to be cleaned, the rotating plate 22 is rotated outward to drive the threaded rod 21 to rotate out, so that the pull-out plate 17 is released from the limit, and then the pull-out plate 17 is pulled upward to pull out the exhaust fan 19. At this time, the exhaust fan 19 is cleaned, and after completion, the pull-out plate 17 is put back to reset the exhaust fan 19, and then the rotating plate 22 is rotated inward to make the threaded rod 21 rotate into the limit groove 24, so that the pull-out plate 17 is limited, thereby achieving convenient cleaning of the exhaust fan 19. By setting the third slide groove 25 and the third slider 26, the pull-out plate 17 is more stable during the process of pulling out and putting back, thereby improving the cleaning efficiency of the exhaust fan 19.
