[0022] Specifically, the cleaning assembly 4 consists of seven parts: a support frame 401, a motor 402, a rotating rod 403, a connecting rod 404, a fan blade 405, a mounting plate 406 and a cleaning brush 407. The support frame 401 is fixedly connected to the inner wall of the mounting tube 1, the motor 402 is fixedly mounted on the support frame 401, the rotating rod 403 is fixedly connected to the output shaft of the motor 402, the other end of the rotating rod 403 is fixedly connected to the connecting rod 404, the outer surface of the rotating rod 403 is fixedly connected to three fan blades 405, the other end of the connecting rod 404 is fixedly connected to the mounting plate 406, and the mounting plate 406 is fixed A cleaning brush 407 is connected, and the left side of the cleaning brush 407 is in contact with the outer surface of the barrier net 3. The fan blade 405 is located on the left side of the barrier net 3. The ventilation volume is adjusted by controlling the rotation speed of the fan blade 405 to achieve more refined ventilation adjustment. While ensuring indoor air circulation, it effectively prevents pest invasion. The connecting rod 404 is driven to rotate by the rotating rod 403, and then the cleaning brush 407 is driven by the mounting plate 406 to clean the dust and dirt accumulated on the barrier net 3. At the same time, air blowing is performed with the cooperation of the motor 402, the rotating rod 403 and the fan blade 405 to regularly clean the dust and dirt on the surface of the barrier net 3.

[0023] Specifically, by arranging the ventilation net 2 to be located on the left side of the blocking net 3, the mesh size of the ventilation net 2 is larger than the mesh size of the blocking net 3, thereby making the overall structure more reasonable.

[0024] Specifically, three fan blades 405 are arranged radially and evenly distributed on the outer surface of the connecting rod 404 with the connecting rod 404 as the center. The motor 402 drives the fan blades 405 to rotate through the rotating rod 403 to adjust the ventilation volume, thereby achieving more refined ventilation adjustment, ensuring indoor air circulation, and effectively preventing pest invasion.

[0025] Specifically, a connecting ring is fixedly installed at the center of the barrier net 3, and the right end of the connecting rod 404 passes through the connecting ring and extends to the right side of the connecting ring, thereby making the overall structure more stable.

[0026] When implementing, follow these steps:

[0027] 1) First, the mesh sizes of the ventilation net 2 and the barrier net 3 are different. The mesh size of the barrier net 3 is moderate, which can effectively prevent the invasion of small insects and small animals, while the mesh size of the ventilation net 2 is large, which can ensure air circulation;

[0028] 2) Then, by setting a cleaning assembly 4, the connecting rod 404 is driven to rotate by the rotating rod 403, and then the cleaning brush 407 is driven by the mounting plate 406 to clean the dust and dirt accumulated on the barrier net 3;

[0030] In summary, the insect and rodent proof net for the exhaust duct is provided with a ventilation net 2 and a barrier net 3, and the mesh sizes of the ventilation net 2 and the barrier net 3 are different. The mesh size of the barrier net 3 is moderate, which can effectively prevent the invasion of small insects and small animals, and the mesh size of the ventilation net 2 is larger, which can ensure air circulation. By providing a cleaning component 4, the ventilation volume is adjusted by controlling the rotation speed of the fan blades 405, so as to achieve more refined ventilation adjustment, and effectively prevent the invasion of pests while ensuring indoor air circulation. The connecting rod 404 is driven to rotate by the rotating rod 403, and then the cleaning brush 407 is driven by the mounting plate 406 to clean the dust and dirt accumulated on the barrier net 3. At the same time, air blowing is performed with the cooperation of the motor 402, the rotating rod 403 and the fan blades 405, and the dust and dirt on the surface of the barrier net 3 are regularly cleaned to prevent pests from breeding in the net. This solves the problem that the insect and rodent proof net for the exhaust duct on the market currently has dust and dirt accumulation after long-term use, which in turn affects the ventilation effect.
