Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Referring to Figures 1-3, an exhaust device includes a first pipe 1, with a second pipe 2 communicating with its interior at one end. Adjustment mechanisms connected to the second pipe 2 are provided on both sides of the first pipe 1. Each adjustment mechanism includes a housing 3 fixedly mounted on the outer wall of the second pipe 2. A partition 11 is provided inside the housing 3. A rotating shaft 8 located above the partition 11 is rotatably connected to one side wall of the housing 3. A worm gear 9 is fixedly mounted at one end of the rotating shaft 8. A worm 5 is rotatably connected between the top of the partition 11 and the inner wall of one end of the housing 3. The worm 5 meshes with the worm gear 9, and the worm gear 9 cooperates with the worm 5 to achieve… Power transmission and deceleration make the adjustment process smoother. Two connecting rods 10 are slidably connected to the partition 11. The connecting rods 10 serve as the connecting parts between the mounting frame 6 and the worm gear 9 to realize the transmission of force. The ends of the two connecting rods 10 away from the second tube 2 are fixedly connected to the same mounting frame 6. The drive rod 7 is rotatably connected to the side wall of the worm gear 9 near the mounting frame 6. One end of the worm 5 passes through the inner wall of one end of the outer shell 3 and is fixedly installed with a knob 4 located outside the outer shell 3. The mounting frame 6 is located on the side of the worm gear 9 away from the rotating shaft 8. The drive rod 7 passes through the mounting frame 6 and is slidably connected to the inner wall of the mounting frame 6.

[0020] Two connecting rods 10 are fixedly connected to the same mounting block 12 at one end near the second pipe 2. A poking rod 13 is fixedly installed on the side wall of the mounting block 12 near the second pipe 2. A mounting cylinder 15 is rotatably connected to the second pipe 2. An adjusting block 16 located inside the second pipe 2 is fixedly installed on the outer wall of the mounting cylinder 15. The adjusting block 16 changes the ventilation area and airflow direction of the second pipe 2 by rotation, thereby controlling the exhaust volume. A sealing ring 17 is provided on the outer wall of the adjusting block 16 between the adjusting block 16 and the inner wall of the second pipe 2. The sealing ring 17 ensures the sealing between the adjusting block 16 and the inner wall of the second pipe 2 to prevent air leakage. A sliding groove 14 is provided on the poking rod 13. A slider 18 is fixedly installed on the inner wall of the mounting cylinder 15. One end of the poking rod 13 is located inside the mounting cylinder 15. The sliding groove 14 is arc-shaped and extends along the axial direction of the poking rod 13. The slider 18 is located inside the sliding groove 14 and is slidably connected to the sliding groove 14.

[0021] In use, this utility model allows the worm gear 5 to rotate by turning the knob 4. The worm gear 5 meshes with the worm wheel 9, which in turn rotates the shaft 8 and the worm wheel 9. When the worm wheel 9 rotates, the two connecting rods 10 and the drive rod 7 cooperate with the mounting frame 6, causing the mounting frame 6 to move up and down. Ultimately, this causes the mounting block 12 and the chuck rod 13 to move down. The slider 18 and the slide groove 14 cooperate to rotate the mounting cylinder 15 and the adjusting block 16. This allows for adjustment of the airflow direction and exhaust area on both sides of the first pipe 1 in the second pipe 2, making it convenient to use.
