Abstract
The utility model discloses an air guiding device of a folding type fan. The air guiding device of the folding type fan comprises a base seat for generating fundamental air flow. An impeller and a motor for driving the impeller to rotate are arranged in the base seat. A ring-shaped nozzle is provided with an inner channel for receiving the fundamental air flow, and an air outlet seam is arranged in the ring-shaped nozzle. The fundamental air flow is emitted from the air outlet seam, and the fundamental air flow emitted by the air outlet seam pulls and absorbs outside air to form air flow. The air guiding device of the folding type fan is characterized in that the ring-shaped nozzle is provided with two air inlet ends, wherein the end faces of the two air inlet ends are round. A ventilation part matched with the air inlet ends of the ring-shaped nozzle is arranged in the base seat, and the air inlet end of the ring-shaped nozzle and the ventilation part can rotate relatively. An air inlet end of the ventilation part is connected with an air outlet of the impeller, and two air outlet ends of the ventilation part are connected with the air inlet ends of the ring-shaped nozzle. A flow guiding face is arranged in the ventilation part, and the flow guiding face guides entered air flow from the air inlet end of the ventilation part to the air outlet ends. The function that the ring-shaped nozzle is folded is achieved, and the air guiding device of the folding type fan is little in occupied space after being folded.

Summary of the invention
The purpose of this utility model is: a kind of nozzle give vent to anger efficient, wind-guiding device of the collapsible fan of the fan noise of Jiang Diing greatly of improving is provided.
In order to reach above purpose, the utility model is achieved through the following technical solutions:
A kind of wind-guiding device of collapsible fan comprises: for generation of the pedestal of basic air-flow, be provided with impeller in the pedestal and be used for the drives impeller motor rotating, annular nozzle is provided with for the inner passage that receives basic air-flow, annular nozzle is provided with the air-out seam, the basis air-flow sews emission by this air-out, and the basic air-flow of air-out seam emission is dragged and inhaled outside air formation air-flow; It is characterized in that: described annular nozzle is provided with two inlet ends that end face is rounded, has the vent that matches with the annular nozzle inlet end in the pedestal, can relatively rotate between the inlet end of annular nozzle and vent, the inlet end of described vent links to each other with the impeller exhaust outlet, two outlet sides of vent link to each other with the inlet end of annular nozzle, be provided with guide face in the vent, the air flow guiding that guide face will enter from the inlet end of vent is to the outlet side.
Advantage of the present utility model is: because annular nozzle is provided with two inlet ends that end face is rounded, has the vent that matches with the annular nozzle inlet end in the pedestal, make and to relatively rotate between the inlet end of annular nozzle and vent, to realize the function that annular nozzle is folding, it is little to take up room after making the wind-guiding device of collapsible fan of the present utility model folding.Because be provided with guide face in the vent, the air flow guiding that guide face will enter from the inlet end of vent is to the outlet side, when air-flow enters the vent of threeway shape, guide face meeting dredging flow, thereby reduced windage, improved the vent efficient of giving vent to anger, simultaneously also reducible noise.
In the utility model, described guide face is the cambered surface with cone-shaped top.Guide face adopts said structure, and it is beneficial to dredging flow, thereby has reduced windage, has improved the vent efficient of giving vent to anger, and simple in structure, easily manufactured.
In the utility model, be provided with the noise reduction flow distribution plate in the described vent, the noise reduction flow distribution plate is located in the inlet end of vent.Flow distribution plate can disturb the spiral helicine air-flow of impeller exhaust outlet, forms dredging flow, thereby has reduced windage, has improved the vent efficient of giving vent to anger, and can reduce noise greatly.
In the utility model, described cone-shaped top is located on the projection line of medial axis of air intake, and the noise reduction flow distribution plate is located on the medial axis of air intake, and cone-shaped top and noise reduction flow distribution plate are vertical setting.Guide face and flow distribution plate adopt said structure, and it is beneficial to dredging flow, thereby has reduced windage, have improved the vent efficient of giving vent to anger, and simple in structure, easily manufactured.
