The disassembly of the filter screen can filter the small particles of impurities in the air. The small particles of impurities can be collected by setting the collection box and discharged by opening the airtight door. The harmful substances in the air can be removed by setting the activated carbon adsorption screen. Adsorption is carried out, and the filter screen and activated carbon adsorption screen can be cleaned and replaced by opening the airtight door one. By setting a single drive motor, the fan blades on the two rotating shafts can be driven to rotate, thereby saving a certain amount of cost and reducing energy consumption. The setting of the deflector can prevent the wind in the air inlet duct from flowing backwards.
