Description
Technical field
The utility model is related to fan technology fields, and in particular to a kind of fan of blasting high-efficiency.
Background technology
Fan is a kind of common electrical equipment, and existing electric fan blade is typically by three pieces or five fan blade
Composition, blade is extended by axial portions, and since blade is longer, after fan electromotor band movable vane piece rotation, the wind speed of generation is edge
Highest, center is minimum, and the wind speed of central part is low, is easy to form turbulent flow, can not blow farther out, central part wastes motor
Energy makes the less efficient of fan blade, and in addition to this, blade blowout is rotary wind, and traditional fan screen is by circle
Steel wire is made, and without guide functions, wind is after blowing out a distance, and due to the effect of centrifugal force, wind meeting four, which dissipates, floats, user
Feel that air quantity is little.
Utility model content
For the defects in the prior art, the utility model provides a kind of fan of blasting high-efficiency, is sent with improving fan
The efficiency of wind, wind speed is more stable, noise smaller.
The utility model provides a kind of fan of blasting high-efficiency, including electric fan and is used for driving fan fan blade rotating
Dynamic motor, is provided with connecting plate in the middle part of the electric fan, and the connecting plate is smooth platy structure, in connecting plate
The heart is connected with the output shaft of the motor, and the outer peripheral edge of connecting plate is connected with an annular frame, the outer peripheral edge of the annular frame
At least 7 blades are distributed in annular array.
Using the above structure, multiple blades are distributed in the periphery of annular frame, when motor drives electric fan rotation, outside
The blade linear velocity enclosed is much larger than the speed of inner ring, and inner ring is connecting plate, is equivalent to the blade for eliminating inner ring, all blade collection
In in outermost, keep the wind speed that rotation generates consistent, traditional blades will not be formed because the inconsistent formation of inside and outside wind speed turbulent flow,
Connecting plate is smooth platy structure, and when rotation not will produce sinuous flow and noise, and therefore, which improves the effect of air-supply
Rate, wind speed is more stable, noise smaller.
Further, the distance between axle center of the annular frame and the electric fan and the outer edge of blade and the wind
The ratio for fanning the distance between axle center of flabellum is more than 0.5.
Further, it is enclosed with guard around the electric fan, the guard includes front mesh enclosure and rear net cover, described
Front mesh enclosure has the diversion division of blade setting described in the recessed portion of connecting plate setting and face described in face, the recessed portion phase
It is recessed inwardly for diversion division, the rear net cover is connected on the outer cover of motor.By being arranged recessed portion, not only good appearance,
And the blade air duct of annular is formed in guard, turbulent flow is advantageously reduced, noise is reduced.
Further, the spoke that the diversion division is radiated from several outer rims from front mesh enclosure recessed portion to the outer profile of front mesh enclosure
Item forms, and the spoke is laminated structure.The wind of blade blowout is the wind of rotation, and the wind of rotation becomes after the spoke of sheet
The wind of straight line improves the air quantity of air-supply and the distance of air-supply.
Further, the ratio of the size of the width and depth of the spoke is less than 0.5.
Further, the inner fovea part of the front mesh enclosure is the reticular structure of hollow out, the inner fovea part and diversion division one at
Type.Beauty, convenient for manufacture.
Further, the inner fovea part of the front mesh enclosure is provided centrally with Decorative Cover.
Further, the connecting plate is in the arc or tapered smooth structure of indent.When electric fan rotates, air-flow can be right
Blade generates an active force backward, by that in the bowl-shape or tapered smooth structure of indent, can reduce connecting plate setting
The moment of flexure that the active force generates connecting plate ensures that structure is not easy to deform to the ability to bear of connecting plate.
The utility model has the beneficial effects that：Multiple blades of the utility model are distributed in the periphery of annular frame, work as electricity
When machine drives electric fan rotation, peripheral blade linear velocity is much larger than the speed of inner ring, and inner ring is connecting plate, is equivalent to cancellation
The blade of inner ring, all blades concentrate on outermost, keep the wind speed that rotation generates consistent, will not form traditional blades because interior
The turbulent flow of the outer inconsistent formation of wind speed, connecting plate are smooth platy structure, and when rotation not will produce sinuous flow and noise, therefore,
The fan structure improves the efficiency of air-supply, and wind speed is more stable, noise smaller.
