The fan comprises a base used for producing base airflow; a nozzle is provided with an internal channel used for receiving the base airflow; the nozzle is annular; the annular nozzle is provided with an opening for air to pass; an air outlet gap is arranged on the nozzle; the base airflow is emitted through the air outlet gap; the base airflow emitted through the air outlet gap sucks external air to form an airflow; and the air outlet gap is delimited by two inner side surfaces. A plurality of connecting sections are arranged in the air outlet gap for connecting with the two inner side surfaces of the air outlet gap, and the connecting sections and the two inner side surfaces are an integrated whole; and the distance in the narrowest position between the two inner side surfaces of the air outlet gap is 0.3 to 5 millimeters. As the plurality of the connecting sections are arranged in the air outlet gap for connecting with the two inner side surfaces of the air outlet gap, and the connecting sections and the two inner side surfaces are an integrated whole, the air outlet gap is always kept to be in a set width, relative displacement of the two inner side surfaces, which is likely to be generated during the processes of manufacture and operation, is avoided, the air outlet of the fan is reliable, and the performance of the fan is more ideal.
Description
Technical field
The present invention relates to a kind of fan.
Background technique
At present, various fan structures are numerous.Like Chinese patent a kind of " fan " just proposed for No. 200910253241.6.This technological scheme discloses a kind of no flabellum fan component that is used to form air-flow, and this fan component comprises and be loaded into a nozzle on the pedestal that this pedestal is used to produce the air-flow that passes nozzle; This nozzle comprises an inner passage, is used for receiving air-flow from pedestal; Air communication is crossed a mouth and is launched, and this mouth is limited two inner side surfaces of said nozzle; One group of spacing means is used to separate each surface of nozzle; Nozzle limits an opening, is dragged from the air-flow of said mouth emission from the fan component air outside and inhales through said opening; Wherein, spacing means and first surface are incorporate; Another surface is partial on one of them surface of nozzle, so that spacing means can touch second surface, thereby can separate each surface, and produces above-mentioned deflection and do not have related with spacing means.
Because said fans is to drag suction through the air-flow of mouth emission, the air that makes open rear section forms blowing with the air-flow of mouth emission, when the air-flow of mouth emission is inhomogeneous, then can have a strong impact on wind-force.Simultaneously, the spacing means of said fans and first surface are one, and spacing means touches second surface, and separates each surface.Thereby use said fans not enough below existing: make and using process in, be easy to because of the displacement of spacing means or to contact the undesirable fan mouth that causes inhomogeneous, thereby have a strong impact on wind-force, make that the performance of fan is undesirable.
Summary of the invention
The objective of the invention is to: provide a kind of fan mouth size fixing, be beneficial to the fan that produces reliable wind-force.
In order to reach above purpose, the present invention realizes 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 invention has the advantages that: 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 present invention, 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 present invention, two inner side surfaces of said air-out seam the distance at narrow place be 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 present invention, two inner side surfaces of said air-out seam the distance at narrow place be 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 present invention, 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 present invention, 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 present invention, described lead-in chamfered and open centre axial direction are 6 degree angles.It can make the air-out of fan ideal.
