| description | The utility model discloses an air flow detection device which comprises a vacuum pump, a first connecting pipe, a second connecting pipe, calibration equipment and an air leading-in module. The air leading-in module, the second connecting pipe, the calibration equipment, the first connecting pipe and the vacuum pump are connected in sequence to form an internally-through structure. The air leading-in module comprises a first air leading-in unit and a second air leading-in unit, and the first air leading-in unit and the second air leading-in unit are connected in series and form an internally-through structure. According to the air flow detection device provided by the utility model, the plurality of air leading-in units are connected in series to form the air leading-in module, so that aplurality of products can be detected at the same time, and the detection time is effectively shortened and the detection efficiency is improved when the products with different flows need to be detected in a detection chambe |
