Air leakage prevention detection device for fire mask production

The invention discloses an air leakage prevention detection device for fire mask production, and particularly relates to the field of air leakage prevention detection.The air leakage prevention detection device comprises a host, an elastic head mold is arranged on the host, and the elastic head mold is used for being supported in a fire mask during detection; the simulation assembly comprises a main body part, a lower jaw part and a first driving part, the lower jaw part is hinged to the lower side of the main body part, and the first driving part is used for driving the lower jaw part to swing up and down. According to the invention, the lower jaw part swings up and down, so that the opening and closing condition of the mouth of a person can be simulated, the stretching of human face muscles can also be simulated, if air leakage occurs during detection, different gases are mixed, and whether the fire mask leaks or not can be judged by detecting the content of the test gas in the mixed gas; and the fire mask
