In order to reach above purpose, the utility model is realized through following technological scheme:
A kind of fan comprises: the pedestal that is used to produce basic air-flow; Nozzle is provided with the inner passage that is used to receive basic air-flow; Described nozzle is an annular nozzle, and annular nozzle has the opening that can supply air to pass through, and nozzle is provided with the air-out seam; The basis air communication is crossed this air-out seam and is launched, and the basic air-flow of air-out seam emission is dragged and inhaled outside air and form air-flow; Described air-out seam is limited two inner side surfaces; It is characterized in that: be provided with two inner side surfaces that some linkage sections are used to connect the air-out seam in the described air-out seam, linkage section and two inner side surfaces are one; Two inner side surfaces of the said air-out seam distance at narrow place are the 0.3-5 millimeter.
The advantage of the utility model is: owing to be provided with two inner side surfaces that some linkage sections are used to connect the air-out seam in the air-out seam, linkage section and two inner side surfaces are one; Make the width of air-out seam remain the width of setting, avoided the issuable relative displacement in manufacturing and using process of two inner side surfaces, thereby made that the air-out of this practical fan is reliable that fan performance is better.When two inner side surfaces of air-out seam when the distance at narrow place is the 0.3-5 millimeter, its air-out that can guarantee fan is reliable.
In the utility model, described nozzle comprises leading portion and back segment, takes the leading portion of wind seam and the inner passage that back segment is combined to form nozzle out of.It can guarantee that air-out seam width is under the situation of setting width all the time, makes that the manufacturing of nozzle is more convenient.
In the utility model, two inner side surfaces of the said air-out seam distance at narrow place are the 1-3 millimeter.When the distance between two inner side surfaces of air-out seam was the 1-3 millimeter, the air-out of fan was comparatively desirable.
In the utility model, two inner side surfaces of the said air-out seam distance at narrow place are 1.5 millimeters.When the distance between two inner side surfaces of air-out seam was 1.5 millimeters, the air-out of fan was ideal.
In the utility model, described air-out seam is provided with lead-in chamfered, and lead-in chamfered length is greater than 2 millimeters, and lead-in chamfered and open centre axial direction are 0.2-20 degree angle.Above-mentioned lead-in chamfered can guide the direction of basic air-flow, the air-flow that it can converge the emission of air-out seam, and the air-flow that is beneficial to the emission of wind seam is dragged the suction outside air.
In the utility model, described lead-in chamfered and open centre axial direction are 1-10 degree angle.It can make the air-out of fan comparatively desirable.
In the utility model, described lead-in chamfered and open centre axial direction are 6 degree angles.It can make the air-out of fan ideal.
