The mode adopted by the current plant tobacco generating device mainly comes from GJB6114-2007 evaluation method for preventing plant tobacco interference of chemical reconnaissance device materials, and the generating mode is a static generating mode. The working mode is that the ignited grass sample is directly placed in a generating cabinet for a fuming test. When the smoke concentration is too low, the grass samples are combusted to increase the smoke inlet amount, and when the smoke concentration is too high, the smoke exhaust amount is increased to dilute the smoke concentration in the box body. The balance of the smoking of the grass sample and the discharge of excess smoke is adjusted by continuously igniting the grass sample to produce smoke of the desired concentration. And when the smoke concentration meets the requirement, the smoke inlet and the smoke outlet are closed simultaneously, and the static balance of the smoke concentration is maintained.
