[0002] An air disinfection machine is a machine that disinfects air through principles such as filtration, purification, and sterilization, and is applicable to the air disinfection of spaces such as operating rooms, treatment rooms, and wards. In addition to killing bacteria, viruses, molds, spores, etc., that is, so-called sterilization and disinfection, some models can also remove organic pollution gases such as formaldehyde and phenol in indoor air, and can also kill or filter allergens such as pollen. With the improvement of people's living standards, people pay more and more attention to the quality of the air in the environment where they are located. The existing air disinfection machines have poor disinfection effects, the internal disinfection structure is not convenient for disassembly and assembly, and at the same time, impurities carried in the air entering the inside of the disinfection machine are also likely to cause bump damage, and the impact on the air inlet will also easily affect the subsequent use of the disinfection machine.
