[0002] Ventilation equipment is a kind of safety equipment widely used in industrial production and life to discharge the harmful gases produced by it from the working space, because it is often used in industrial production plants, biological and chemical laboratories of research and development institutions, and kitchens during cooking. Various harmful gases, odors, moisture, and flammable, explosive, and corrosive substances will be produced. In order to protect the personal safety of operators or users, prevent these toxic and harmful substances from spreading into the working space or use space , Industrial plants, biological and chemical laboratories, and kitchens are usually equipped with ventilation equipment to discharge these toxic and harmful substances, so as to prevent operators or users from inhaling these toxic and harmful substances, which will endanger their personal safety. Or the toxic and harmful substances in the use space are discharged. The existing ventilation equipment generally has a make-up air channel that connects its work space or use space with the external environment, so as to push the work space or Toxic and harmful gases in the use space smoothly flow into the exhaust channel, and then discharged to the working space or outside the use space, thereby reducing the risk of operators or users inhaling toxic and harmful gases. Therefore, the supplementary air channel of the existing ventilation equipment cannot be adjusted. The speed of the wind, and the lack of supplementary air outlets, reduce the exhaust effect of the ventilation equipment, and the existing supplementary air ducts cannot filter the polluted gas and dust in the air, so the discharged gas still causes pollution. We propose a Ventilation equipment and usage method of supplementary air duct
