[0020] To be more specific, a fan 22 for air mixing is disposed inside the sealed box 2 .
[0021] A method for testing the air permeability of footwear comprises the following steps: S1: Select the same size of shoe samples, and choose different types of shoe samples for comparison; S2: Put the shoe sample on the shoe mold 8 in the sealed box 2, adjust the positions of the multiple detection probes 18, and measure the carbon dioxide gas content in the sealed box 2 without introducing carbon dioxide and record the data; S3: After completing the data detection without the introduction of carbon dioxide, start the air pump 5 to introduce carbon dioxide gas into the sealed box 2 for a certain period of time, and use the fan 22 to mix the air in the sealed box 2 so that the gas in the sealed box 2 is evenly mixed, and then measure the growth rate of the carbon dioxide gas in the sealed box 2 through the carbon dioxide detector 6 and record the data; S4: Replace different types of shoe samples, repeat the above steps, and judge the air permeability of the shoe samples by observing the growth rate of carbon dioxide gas.

The control group shoe samples are first placed on the shoe mold 8. After the sealed box 2 is closed, the carbon dioxide detector 6 is used to monitor the carbon dioxide content in the sealed box 2 and record the data. Then, the air pump 5 is started to extract the carbon dioxide gas in the gas tank 4 and pass it into the shoe mold 8 for a certain period of time. The introduced carbon dioxide gas is released into the control group shoe sample through the air vent 10, and then released into the sealed box 2 through the air permeability of the control group shoe sample. When the carbon dioxide content in the sealed box 2 increases, the monitoring data of the carbon dioxide detector 6 will change. The growth rate of the carbon dioxide content is recorded to evaluate the air permeability of the control group shoe sample. Finally, experiments are carried out by changing different types of shoe samples and recording the experimental data, so as to evaluate the air permeability of different types of shoes.
