The invention belongs to the technical field of cigarette quality control, and especially relates to a cigarette combustion detection device, a cigarette combustion detection method and an applicationthereof. The cigarette combustion detection device comprises a rotating disc type smoking unit, a sucker, a clamping rotating unit, a cigarette ash knock-down unit, an observation unit, a linear scanning unit and a control unit. The invention further provides a cigarette combustion detection method. The invention further provides the application of the cigarette combustion detection device or thecigarette combustion detection method. In the detection device provided by the invention, the linear scanner can rotate a cigarette when scanning the cigarette, the linear scanner can splice the pictures after scanning the cigarette surfaces line by line, thereby effectively preventing distortion; and the technical defects that the distortion is easily produced in a detection result image and thedetection efficiency is low in the method for evaluating and detecting the defects of the cigarette in the combustion process in the prior art can be solved.
