The top of the box 3 is fixedly connected to a housing 6. The inner side of the housing 6 is movably connected to an exhaust pipe 7. The side of the housing 6 is fixedly connected to a box 8. The bottom of the box 8 is provided with a lifting assembly 9. The bottom of the lifting assembly 9 is provided with a clamp 10.

[0023] It should be noted that the filter layer 5 is made of polyester fiber. Polyester fiber can remain stable in high-temperature environments and is not easily deformed or melted. At the same time, it can effectively capture oil fumes and fine particles, providing a good filtration effect.

[0024] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The lifting assembly 9 includes a first motor 11, which is fixedly connected to the inside of the housing 8. The output end of the first motor 11 is fixedly connected to a first transmission wheel 12 via a coupling. A transmission chain 13 is rotatably connected to the side of the first transmission wheel 12. A second transmission wheel 14 is sleeved on the inner side of one end of the transmission chain 13. A threaded rod 15 is fixedly connected to the bottom end of the second transmission wheel 14. A column 16 is threadedly connected to the side of the threaded rod 15. A fixing plate 17 is fixedly connected to one end of the column 16. The bottom end of the fixing plate 17 is fixedly connected to the clamp 10.

[0025] It should be noted that: the upper two ends of the fixing plate 17 are fixed with columns 16. The fixing plate 17 and the two columns 16 cooperate to form a limiting structure to prevent the columns 16 from rotating with the threaded rod 15.

[0026] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The side of the mounting plate 4 is attached to the inside of the box 3, and the mounting plate 4 and the inside of the box 3 form a sliding connection.

[0027] It should be noted that: one end of the mounting plate 4 is provided with a handle, and the filter layer 5 and the top of the mounting plate 4 form an interlocking structure.

[0028] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The diameter of the first transmission wheel 12 is the same as the diameter of the second transmission wheel 14, and the first transmission wheel 12 and the second transmission wheel 14 are always on the same horizontal line.

[0029] It should be noted that two transmission chains 13 are distributed at equal distances and staggered on the side of the first transmission wheel 12.

[0030] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 One end of the exhaust pipe 7 is fixedly connected to a circular hollow piece 18. An annular groove 20 is provided on the inner side of the housing 6. The side of the circular hollow piece 18 fits against the inner side of the annular groove 20, and the circular hollow piece 18 and the annular groove 20 form a sliding connection.

[0031] It should be noted that the height of the annular groove 20 is twice the height of the circular hollow piece 18, and the circular hollow piece 18 limits the exhaust pipe 7 through the annular groove 20.

[0032] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 A square hollow piece 19 is fixedly connected to the lower part of the circular hollow piece 18. A square groove 21 is provided below the annular groove 20. The shape of the square groove 21 is the same as that of the square hollow piece 19. The square hollow piece 19 limits the circular hollow piece 18 through the square groove 21.

[0033] It should be noted that the square hollow piece 19 and the square groove 21 form an interlocking structure.

[0034] The working principle of the exhaust device for a barbecue grill provided by this utility model is as follows: The user clamps the device next to the grill using the clamp 10. The exhaust fan 2 inside the outer shell 1 draws in the smoke, which is then exhausted through the exhaust pipe 7. The filter layer 5 inside the housing 3 filters the fumes, preventing excessive grease from adhering to the inner wall of the exhaust pipe 7. After use, the filter layer 5 can be replaced using the mounting plate 4. The lifting component 9 inside the housing 8 can adjust the distance between the device and the fumes, making it suitable for different usage situations. The first motor 11 drives the first transmission wheel 12 to rotate, and the transmission chain 13 on the side of the first transmission wheel 12 drives the second transmission wheel 14 to rotate synchronously. The second transmission wheel 14 drives the threaded rod 15 to rotate, which in turn drives the column 16 to move up and down. To prevent the column 16 from rotating with the threaded rod 15, the fixing plate 17 can limit the column 16, thus allowing the two columns 16 to rise and fall smoothly. According to the usage requirements, the orientation of the exhaust pipe 7 can be adjusted by the circular hollow piece 18 at the bottom of the exhaust pipe 7. The circular hollow piece 18 rotates smoothly inside the annular groove 20. The square hollow piece 19 at the bottom of the circular hollow piece 18 engages with the square groove 21. The square hollow piece 19 and the square groove 21 cooperate to limit the exhaust pipe 7 and prevent the angle of the exhaust pipe 7 from deflecting during use.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
