Description
Technical field
The present invention relates to household electrical appliance technical fields, more particularly to fan structure.
Background technology
Fan is a kind of common small household appliances, and the composition of fan is very simple, is exactly blade, motor, bearing and frame.But
To be a fan will accomplish that air quantity is big, mute or even rotating speed is controllable, it is desired nonetheless to which some many technologies are supported.Fan electricity
Machine generally use DC brushless motor, fan blade shape common are sickle, trapezoidal and AVC patents flanging type etc..Phase
For, sickle flabellum is quieter when operating, but the wind pressure generated is also smaller；Trapezoidal flabellum easy tos produce greater pressure,
But noise is relatively also larger.Flanging type is relatively good design, and larger wind pressure, but mesh can be generated while keeping low noise
Before be only used in the product of AVC, the blade of cpu fan is usually between 6 to 12.It is, in general, that the less appearance of blade quantity
It is also easy to produce larger wind pressure, but running noise is also larger；And more then just the opposite of blade quantity.Above several fan blade
All there is wind-force deficiency, less efficient, wind-force dissipates the shortcomings of overflowing.
Invention content
The object of the present invention is to provide a kind of electric fans, it can efficiently reduce air drag, will not leak out, efficiency compared with
Height, wind energy and utilization rate of electrical are high, and wind-force is powerful, lossless, overflow without dissipating.
The mesh of the present invention is achieved through the following technical solutions：A kind of electric fan, including the engine base of underbelly with
And the fan head on top, guard envelope is outside whole flabellum, and rear end is fixed by four screws with fan head front end, and leaf dish is
Flat circular configuration, the center of circle are equipped with the through-hole being interference fitted with the flange of flange, and 90 degree of angles are set center of circle radiation direction each other
There are fusiformis diversion trench, periphery to be equipped with collection wind edge；The blade of flabellum is small black tile shape, and middle part is fixed in the diversion trench of leaf dish,
Four blades, 90 degree of angle arrays each other；Diversion trench surface tangent and leaf dish bottom surface are at degree angle, the motor being located in fan head
Axis and the flange in the leaf dish center of circle are fixed.
The middle part of blade of the flabellum is fixed in leaf dish, and blade is consistent in leaf dish front and back length outstanding.
The wind edge that integrates is cylinder-like structure.
The present invention compared with prior art the advantages of and effect：Using shoe blade and the matched mode of fusiformis diversion trench
Reduce air drag；Leaf dish sum aggregate wind edge is used, the good side of wind direction will not leak out, and efficiency is higher, wind energy and electric energy
Utilization rate is high；So that wind-force is more powerful, and it is lossless, it overflows without dissipating；Whole flabellum also has inertia big, the big feature of wind-force, structure
Simply, the advantages that durability is good.

Specific implementation mode
As shown in Figure 1, a kind of electric fan, including fan leaf 6, guard 5, motor shaft 4, fan head 3, fuselage 1 and engine base 2；
Whole flabellum includes blade 6, leaf dish 7, collection wind edge 8, diversion trench 9 and through-hole 10；The blade 6 of flabellum is fixed on the water conservancy diversion of leaf dish 7
In slot 9, four blades 6 are mutually every 90 degree of angle arrays；Leaf dish 7 is flat disk-shaped structure, and edge is equipped with collection wind edge 8, and bottom is equipped with
The diversion trench 9 of four fusiformis, 9 surface tangent of diversion trench is with 7 bottom surface of leaf dish at 30 degree of angles, and four diversion trenches 9 are mutually every 90 degree of folders
Angle array, 7 centre of leaf dish are equipped with the through-hole 10 being interference fitted with the flange of flange 11；4 one end of motor shaft in fan head 3
It is fixed with the flange 11 in 7 center of circle of leaf dish.Guard 5 is arranged outside whole flabellum, is fixed on fan head 3 by four screws；
1 top of fuselage connects fan head 3, and 1 lower part of fuselage is connect by upright bar with engine base 2.
Further, the blade 6 of the flabellum is small black tile shape, and 6 surface tangent of blade is pressed from both sides with 7 bottom surface of leaf dish at 30 degree
Angle.6 middle part of the blade is fixed in leaf dish 7, and blade 6 is consistent in the length of 7 front and back of leaf dish.The collection wind edge 8 is
Cylinder-like structure.The motor shaft 4 is fixed by bolt and the flange 11 in 7 center of circle of leaf dish.
This entirety fan-leaf fan generating wind-force to be a kind of using whole flabellum, manufactures refrigerant household electrical appliance.Using watt
Shape blade and the matched mode of fusiformis diversion trench reduce air drag；Use the collection of leaf dish and periphery setting cylinder-like structure
Wind edge will not leak out, and efficiency is higher, and wind energy and utilization rate of electrical are high；So that wind-force is more powerful, and it is lossless, it overflows without dissipating；Whole fan
The advantages that leaf also has inertia big, and the big feature of wind-force is simple in structure, and durability is good.When starting this whole fan-leaf fan,
Motor shaft drives whole flabellum to start to rotate, and the blade at the leaf dish back side endlessly collects air quickly by air flow, compels
Gas is set to flow into diversion trench；The positive blade of leaf dish arranges the gas flowed out from diversion trench to right opposite at this time, and it is empty to reach promotion
The effect of flow of air.Excessive moving air is dissipated by blade simultaneously and encounters leaf dish sum aggregate wind edge, can also be forced to arrange to right opposite,
Moving air is arranged to right opposite to the greatest extent, and flabellum is dissipated without air and overflow, and utilization rate is very high, and due to blade, leaf dish and
Integrate wind edge as overall structure, inertia is larger, and wind-force is larger, and noise is smaller, and the service life is higher, durable.
Specific implementation mode of the present invention does not constitute the limitation to the application range, every in present inventive concept
Within spirit and principle, all any modification, equivalent and improvement etc. that one of skill in the art can make should be included in
Within protection scope of the present invention.
