Abstract

The disclosure provides a plasma module, a disinfection and sterilization apparatus, and an air duct assembly. An outer surface of the plasma module at least includes a domed surface and a flat surface, an edge of the domed surface being in sealed connection with an edge of the flat surface. The plasma module further includes a plasma emission probe, at least a part of the plasma emission probe being exposed outside an outer surface of the domed surface; and a plasma generator, the plasma generator being arranged inside the plasma module, and the plasma generator being electrically connected to a part, located inside the plasma module, of the plasma emission probe. By using the plasma module, the wind resistance is reduced, and the flow efficiency of positive and negative ions generated by the plasma generator is improved, so that the sterilization efficiency is increased.
