[0034] Working principle of this utility model:

[0035] Refer to the instruction manual appendix Figures 1-6In use of the utility model, firstly, the fan is fixed to the ceiling of the ceiling by the mounting foot plate 14 of the top four corners of the shell body 1, the air guide pipe 15 is connected with the ventilation pipe in the ceiling, so that the air can flow smoothly;

[0036] The driving motor 16 is started, the output shaft of the driving motor 16 drives the fan blade 17 to rotate, so that the fresh air outside is drawn into the room, when the air passes through the ventilation filter groove 18 on the surface of the protective cover plate 2, the dust and foreign matters in the air are effectively intercepted, so that the air entering the room is more clean, with the lapse of time, the protective cover plate 2 surface will accumulate a certain amount of dust and foreign matters, and needs to be cleaned regularly;

[0037] When cleaning, first, the connecting block 6 is moved along the sliding groove 4 by pushing the handle 5, this step is to release the clamping relationship between the connecting block 6 and the assembly groove 7, then, the handle 5 is pulled down, which drives the whole protective cover plate 2 to move downwards, in this process, the first magnetic ring 11 and the second magnetic ring 12 are separated from the adsorption, and the positioning fence 3 is also pulled out from the bottom opening of the shell body 1, after the above steps are completed, the disassembly of the protective cover plate 2 and the shell body 1 is completed, at this time, the dust and foreign matters on the surface of the protective cover plate 2 can be conveniently cleaned, since the bottom opening of the shell body 1 is in an open state at this time, therefore, the inside of the shell body 1 can also be cleaned by taking this opportunity;

[0038] After cleaning, the protective cover plate 2 is reassembled to the bottom of the shell body 1, first, the handle 5 controls the connecting block 6, so that one end of the connecting block 6 does not protrude through the slot, then, the positioning fence 3 is inserted into the bottom opening of the shell body 1, and the protective cover plate 2 is pushed upwards, so that the first magnetic ring 11 and the second magnetic ring 12 are adsorbed together again, finally, the handle 5 is loosened, the connecting block 6 is re-clamped into the assembly groove 7 under the pushing of the spring 10, and the fixing of the protective cover plate 2 and the shell body 1 is completed.
