As can be seen from the above table, if the thickness of the protection net 146 is too small (the material thickness is 1.5 mm), the strength of the protection net 146 is directly affected, so that the protection net 146 generates resonance sound when the ceiling fan 100 is operated, resulting in noise rise, and thus, the thickness of the protection net 146 is preferably 2 mm to 3 mm. If the interval between two adjacent radial ribs 1461 is too small (the interval between the ribs 1461 is 5mm or 6 mm), the air intake is greatly reduced, and the effect of the ceiling fan 100 is directly affected, so the interval between two adjacent radial ribs 1461 is preferably 7 mm to 10 mm. If the distance between the plane of the protection net 146 and the plane of the ring body 145 is too small (the height of the protection net 146 is 8 mm), the air intake is greatly reduced, and the effect of the ceiling fan 100 is directly affected, so the distance between the plane of the protection net 146 and the plane of the ring body 145 is preferably 10 mm to 16 mm.
