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.

Abstract: The lamp provided in the disclosure includes: a lamp body, a light source and a switch device for controlling the light source, wherein the lamp body forms an installation space and an opening of the installation space, the light source is provided in the installation space and faces towards the opening, the lamp has an exposed portion, and the opening is located at the exposed portion; the switch device is provided in the installation space, and a trigger end of the switch device is provided towards the opening; or the switch device is provided at the opening or adjacent to the opening, and the trigger end of the switch device is exposed outside the exposed portion. The user only needs to detach some components of the exposed portion to expose the trigger end of the switch device, and the user is able to also perform direct observation and operation.

Abstract: The disclosure provides an air purifier. The air purifier includes a shell, a first plasma generator, a filter assembly, a second plasma generator, and a ventilation assembly. An air inlet and an air outlet are formed in the shell. A ventilation channel is formed between the air inlet and the air outlet of the shell. The first plasma generator, the filter assembly, the second plasma generator, and the ventilation assembly are separately arranged in the ventilation channel. In an air outlet direction of the ventilation channel, the first plasma generator is arranged between the air inlet and the filter assembly, and the second plasma generator is arranged between the filter assembly and the air outlet. By adopting the above structure, the first plasma generator is arranged between the air inlet and the filter assembly, and a plasma wall is formed on the periphery of the filter assembly.
