The embodiment of the utility model discloses an automatic air volume adjusting device, which comprises a simulation chamber, an air volume adjusting device and a control device, and is characterized in that the simulation chamber comprises an air inlet fan and an air outlet fan; the nitrogen injection pipeline is used for providing nitrogen into the simulation chamber; the control assembly is electrically connected with the air inlet fan and the air outlet fan and used for controlling the air volume of the air inlet fan and the air volume of the air outlet fan. The control assembly is adopted to adaptively control the air inlet volume and the air outlet volume, so that the control precision and the accuracy of the simulation environment are improved, and in addition, the phenomenon of'peculiar smell 'in the simulation room is greatly improved; the whole automatic air volume adjusting process follows the principle of a single variable, the air volume of inlet air and the amount of nitrogen entering the simula
