Referring to fig. 1 to 3, an air disinfecting and purifying device 100 provided by the present application will be described. The air sterilization and purification device 100 comprises a casing 10, an air pumping assembly, a sterilization and disinfection assembly 40, a purification and filtration assembly 30, an air duct bracket 20 and an air duct assembly 60. The casing 10 is used for protecting the internal components of the air sterilization and purification device 100, the casing 10 has a first air inlet 11, a second air inlet 12 and an air outlet 13, and air can enter the casing 10 from the first air inlet 11 or enter the casing 10 from the second air inlet 12, and then is discharged outside the casing 10 from the air outlet 13. The air extracting component is located in the casing 10 and disposed adjacent to the air outlet 13, and is used for driving the air entering the casing 10 to be discharged from the air outlet 13, so as to extract the air in the casing 10, and further enable the air to enter the casing 10 from the first air inlet 11 and the second air inlet 12, so as to increase the flowing speed of the air in the casing 10, and further increase the air purifying efficiency and the air sterilizing efficiency of the air sterilizing and purifying device 100.

The air duct bracket 20 is disposed in the casing 10 and is used for guiding the air entering the casing 10 from the first air inlet 11 to the air exhausting assembly, that is, after the air enters the casing 10 from the first air inlet 11, the air flows to the air exhausting assembly in the air duct bracket 20 and then is exhausted from the air outlet 13. Meanwhile, the air duct bracket 20 may also be used to guide the air entering the casing 10 from the second air inlet 12 to flow to the air exhausting assembly, that is, after the air enters the casing 10 from the second air inlet 12, the air flows to the air exhausting assembly in the air duct bracket 20 and then is exhausted from the air outlet 13.
