[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] By adding a filter assembly between the baffle plate and the protective plate, the baffle plate can limit and fix the filter assembly, and the protective plate can provide shielding protection for the filter assembly. The filter assembly is not easily damaged by external forces, and when outside air passes between the protective plate and the baffle plate, dust in the air will be filtered out by the filter assembly.
