DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-4A fast dust removal structure of a smoke exhaust device includes a smoke exhaust pipe 1, a connecting assembly is arranged on the surface of the smoke exhaust pipe 1, the connecting assembly includes a connecting sleeve 2 fixedly arranged on the surface of the smoke exhaust pipe 1, a bolt 3 is arranged inside the connecting sleeve 2, and the smoke exhaust pipe 1 is stably connected to other equipment through the cooperation of the connecting sleeve 2 and the bolt 3. A motor 4 is fixedly arranged on the top of the smoke exhaust pipe 1, a threaded rod 5 is fixedly arranged on the output end of the motor 4, and the threaded rod 5 is rotatably arranged with the smoke exhaust pipe 1, and a positioning assembly is arranged on the surface of the threaded rod 5, and the positioning assembly includes a positioning sleeve 6 rotatably arranged on the surface of the threaded rod 5, and a support rod 7 is fixedly arranged on the surface of the positioning sleeve 6, and one end of the support rod 7 is fixed to the inner wall of the smoke exhaust pipe 1. The fixed setting is that the positioning sleeve 6 and the support rod 7 cooperate with each other to prevent the threaded rod 5 from shaking, and at the same time avoid the situation that the threaded sleeve 8 and the threaded rod 5 are separated. The surface of the threaded rod 5 is threadedly provided with a threaded sleeve 8, and the surface of the threaded sleeve 8 is fixedly provided with a connecting rod 9. One end of the connecting rod 9 is fixedly provided with a dust removal ring 10, and the surface of the dust removal ring 10 is overlapped with the inner wall of the exhaust pipe 1, and the inner wall of the exhaust pipe 1 is provided with a limiting component, and the limiting component includes an arc-shaped slide groove 11 opened on the inner wall of the exhaust pipe 1, and a slider 12 is slidingly provided inside the arc-shaped slide groove 11, and the slider 12 is fixed to the surface of the dust removal ring 10, and the number of the arc-shaped slide groove 11 and the slider 12 are both two, and the two arc-shaped slide grooves The arc-shaped slide groove 11 and the slider 12 are symmetrically distributed. The dust removal ring 10 is prevented from rotating by cooperating with the slider 12, thereby preventing the threaded sleeve 8 from being unable to rise and fall. The inner wall of the smoke exhaust pipe 1 is provided with a smoke exhaust component. The smoke exhaust component includes a smoke exhaust pipe 2 13 fixedly arranged on the inner wall of the smoke exhaust pipe 1. The inner wall of the smoke exhaust pipe 2 13 is fixedly arranged with the surface of the filter 15. The inner wall of the smoke exhaust pipe 2 13 is fixedly arranged with a high-temperature resistant fan 14. The setting of the high-temperature resistant fan 14 accelerates the exhaust speed of smoke. The inner wall of the smoke exhaust pipe 1 is provided with a filter 15 through the smoke exhaust component. The filter 15 is in an arc-shaped structure, and the filter 15 is made of metal material to prevent the filter 15 from being deformed. The fast dust removal structure of the smoke exhaust device can drive the threaded rod 5 to rotate forward or reversely through the forward or reverse rotation of the motor 4, so that the threaded rod 5 drives the threaded sleeve 8 to move up and down, the threaded sleeve 8 drives the connecting rod 9, and the connecting rod 9 drives the dust removal ring 10 to move up and down, so as to quickly remove dust from the inner wall of the smoke exhaust pipe 1 and the filter 15, thereby avoiding the situation that the smoke exhaust device can only be cleaned by disassembling and opening it after long-term use. There is no need for staff to disassemble and assemble it, and the smoke exhaust pipe 1 and the filter 15 are automatically cleaned at the same time, which not only improves the cleaning speed but also reduces manpower consumption.

[0021] During use: when exhausting smoke, start the high temperature resistant fan 14 so that the high temperature resistant fan 14 draws out the inside of the smoke exhaust pipe 13, which can increase the speed at which the smoke inside the smoke exhaust pipe 1 is discharged through the smoke exhaust pipe 13. At the same time, during the smoke exhaust process, the filter 15 will filter the smoke. When the inner wall of the smoke exhaust pipe 1 and the filter 15 need to be cleaned after long-term use, it is only necessary to start the motor 4 to drive the threaded rod 5 to rotate, so that the threaded rod 5 drives the threaded sleeve 8 to move downward, thereby causing the threaded sleeve 8 to drive the connecting rod 9, and the connecting rod 9 drives the dust removal ring 10 to move downward. During the operation, the dust removal ring 10 scrapes the inner wall of the smoke exhaust pipe 1 and the filter 15 to remove dust. When the bottom of the threaded sleeve 8 moves to overlap with the top of the positioning sleeve 6, the motor 4 can be started in reverse, so that the motor 4 drives the threaded rod 5 to rotate in the opposite direction, so that the threaded rod 5 drives the threaded sleeve 8 to move upward, the threaded sleeve 8 drives the connecting rod 9, and the connecting rod 9 drives the dust removal ring 10 to move upward for reset. At the same time, the inner wall of the smoke exhaust pipe 1 and the filter 15 are subjected to secondary dust removal. While the smoke exhaust pipe 1 and the filter 15 are automatically cleaned together, the cleaning effect is improved.
