Description
Technical Field
The utility model relates to a fan field, more specifically say, relate to an air duct assembly of fan.
Background
The fan is an electric fan used in hot weather to cool the air, and is a device driven by electricity to generate airflow.
Most of fans used in the current market convert air into airflow to form wind, but in hot summer, the amount of wind blown out by the fans is not large enough, the wind power is not strong enough, the cooling effect is poor, and if an air conditioner is used, electric energy is greatly wasted.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the defect and not enough that prior art handled, provide a wind channel subassembly of fan.
In order to achieve the above object, the utility model discloses the technical scheme who takes is an air duct assembly of fan, including fan housing, set up in flabellum subassembly in the fan housing and be used for the drive flabellum subassembly's driver part, fan housing is including relative air outlet and the air intake that sets up, the diameter of air outlet is greater than the diameter of air intake, flabellum subassembly set up in the fan housing and rather than the inboard wall forms constrictive wind channel.
The fan blade assembly comprises a rotating shaft and fan blades, the rotating shaft is located in the center of the fan shell, the fan blades are arranged on the side wall of the rotating shaft in a surrounding mode, and the driving part is arranged in the rotating shaft.
The thickness of the blades of the fan blade is uniformly changed from small to large along the length direction of the blades and then changed from large to small.
The section of the fan blade component perpendicular to the axial lead of the rotating shaft is gradually increased from the air inlet to the air outlet.
The rotating shaft is in a table shape, and the diameter of the rotating shaft is gradually increased from the air inlet to the air outlet.
The diameter of the side face of the fan shell and the fan blade assembly, which are located on the same plane, is gradually increased from the air inlet to the air outlet.
The driving part is a motor.
The fan blades have 9 pieces.
The utility model has the advantages that:
the utility model provides a wind channel subassembly of fan according to the narrow wind channel of canyon effect design in city, has increaseed the wind-force and the amount of wind of fan simply, has improved the cooling effect of fan, has saved the electric energy simultaneously again, and economic effect is good.
Drawings
Fig. 1 is a schematic view of an air duct assembly of a fan according to the present invention;
fig. 2 is a schematic view of a fan blade of an air duct assembly of the fan according to the present invention;
fig. 3 is a schematic cross-sectional view of a fan blade assembly of an air duct assembly of the fan of the present invention.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the invention, and the direction of the present embodiment is based on the direction of fig. 1.
As shown in fig. 1, an air duct assembly of a fan includes a fan housing 1, a fan blade assembly 2 disposed in the fan housing 1, and a driving component 3 for driving the fan blade assembly 2, the fan housing 1 includes an air outlet 11 and an air inlet 12 disposed opposite to each other, a diameter of the air outlet 11 is greater than a diameter of the air inlet 12, and the fan blade assembly 2 is disposed in the fan housing 1 and forms a narrow air duct with an inner side wall thereof. The utility model discloses according to the narrow wind channel of canyon effect design in city, increaseed the wind-force and the amount of wind of fan simply, improved the cooling effect of fan, saved the electric energy simultaneously again, economic effect is good.
The fan blade assembly 2 includes a rotating shaft 22 located at the center of the fan housing 1 and fan blades 21 annularly disposed on the side wall of the rotating shaft 22, and the driving member 3 is disposed in the rotating shaft 22.
As shown in fig. 1 and 2, the blade thickness of fan blade 21 is uniformly increased from small to large and then decreased from large to small along the length direction. The middle of the fan blade 21 is thick, and the two sides are thin, so that the fan blade 21 is firm and cannot be broken due to overlarge wind pressure.
As shown in fig. 2 and 3, a cross section of the fan blade assembly 2 perpendicular to the axial line of the rotating shaft 22 gradually increases from the air inlet 12 to the air outlet 11. As can be seen at A, B, C, D, E, F in fig. 3, fan blade assembly 2 increases in cross-section from a to F.
The rotating shaft 22 is in a table shape, and the diameter of the rotating shaft 22 gradually increases from the air inlet 12 to the air outlet 11.
The diameter of the side surface of the fan housing 1 and the fan blade assembly 2 located on the same plane gradually increases from the air inlet 12 to the air outlet 11.
The drive means 3 is a motor. The rotation shaft 22 is driven to rotate by the driving part 3, and the rotation shaft 22 drives the fan blades 21 to rotate, and simultaneously stirs air to form wind.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
