[0005] In addition, the visual concentration monitor for online monitoring of cooking fumes in catering enterprises in the prior art cannot perform filtering functions, but only has the function of detection;

[0006] Secondly, the visual concentration monitor for online monitoring of oil smoke in catering enterprises in the prior art cannot be moved, which results in incomplete monitoring and inability to perform real-time monitoring of the entire pipeline;

[0007] Moreover, the visual concentration monitor for online monitoring of cooking fumes in catering enterprises in the prior art cannot view the inner wall of the range hood duct, which results in incomplete real-time monitoring;

[0008] Therefore, a visual concentration monitor for online monitoring of cooking fumes in catering enterprises is designed to solve the above problems. Summary of the invention
