The air supply fan 5 draws the air outside the oven body 1 into the first shell 4 through the air supply pipe 22. The first filter 8 can filter the dust in the air to avoid contaminating the interior of the oven body 1. The filtered air then flows into the interior of the oven body 1 through the air inlet pipe 2, accelerating the gas flow in the oven body, thereby accelerating the heat dissipation speed of the test sample; the exhaust fan 7 draws out the gas inside the oven body 1, so that the gas flows into the second shell 6 through the air outlet pipe 3 and passes through the second filter 9 and the activated carbon board 10 in sequence. The second filter 9 can filter out the particulate impurities contained in the gas, and the activated carbon board 10 can absorb the odor contained in the gas to avoid causing indoor air pollution.
