Black smoke valuing mechanism and black smoke generating device

The utility model belongs to the technical field of tail gas detection, and discloses a black smoke valuing mechanism and a black smoke generating device. The black smoke valuing mechanism comprises a valuing shell, a transparent baffle, a light source and a detection assembly. The transparent baffle is arranged in the constant value shell so as to divide the constant value shell into a gas containing cavity and a constant value cavity which are not communicated with each other, and the gas containing cavity is used for storing black smoke; the light source is arranged in the constant value cavity and used for irradiating light into the gas containing cavity. The detection assembly is arranged in the constant value shell and used for detecting the intensity of light penetrating through the black smoke in the gas containing cavity. The blackness value of the black smoke in the gas containing cavity can be determined through the black smoke value setting mechanism according to the detected light intensity chang
