The specific structural components and filtering principles not described in detail above are already prior art and are common technical knowledge well-known to those skilled in the art, so no more details will be described.

[0036] In the present utility model, through the settings of the first pipeline 10, the second pipeline 11, and the fan 4, the air inside the heating chamber circulates. During the circulation process, it is preliminarily filtered by the filter rack 3. And in the second pipeline, an oil removal plate 12 and an ultraviolet disinfection lamp 13 assembly are arranged for deep filtration and disinfection, and through the setting of the flow dividing plate 9, independent transportation of the air duct is realized, effectively avoiding the situation of cross-contamination and improving the purity of the air inside the box.
