First rib 21, and there is air duct between consecutive web, the exhaust air flue of fan can be adjusted and change blowing range and promoted
Wind speed.
The wind speed for the wind being oriented to air duct faster will be understood by, for example, people are when breathing out, by hand
Flare shape is placed on the speed of gas that the speed of the gas of face both sides exhalation obviously breathes out than usual faster.
For example, by the way that air duct is arranged, inventor has found that under equal conditions the wind of fan blowout passes through the prior art
In front mesh enclosure wind speed be 180m/s, and the front mesh enclosure wind speed passed through in the application is 260m/s, and wind speed obtained significantly carrying
It rises.
Specifically, as shown in Figure 1, Figure 2 and Figure 3, cover body 10 is in the ring discoid with central through hole 11.Decoration 20

The air duct for penetrating through decoration 20 along the longitudinal direction is formed between one rib 21.
Wherein, there are multiple gaps, the wind that gap allows fan to blow out to pass through between multiple the first adjacent ribs 21, this
Gap namely air duct, it is to be understood that the front mesh enclosure 100 of the air duct that is formed between two neighboring first rib 21 in fan
There is certain width, being also equivalent to air duct, there is certain length, the side of the first rib 21 to limit wind direction four in axial direction
Week diffusion, that is to say, that air duct has guiding role to wind, and therefore, air duct has certain width (to be greater than in front-rear direction
5 millimeters), multiple air ducts can converge at least part wind blown out from fan, in this way, being equivalent to the blowing face of reducing
Product, therefore, wind speed faster, also improves the air supplying distance of fan, and user receives blowing, comfort level higher a long way off.Some realities
It applies in example, as depicted in figs. 1 and 2,21 curved strip of the first rib.In this way, the shape in the air duct between two consecutive webs
It is restricted to curve strip, for straight air duct, every curve air duct can blow out more wind.Certainly, above-mentioned implementation
