Description
Technical field
The utility model is related to flabellum technical field, more particularly to a kind of flexible flabellum.
Background technology
Flabellum is the constituent of desk fan and ceiling fan, is driven by motor, rotates to generate the component of wind.The flabellum of ceiling fan
Usually three pieces, the flabellum of desk fan is usually five, and the section of common electric fan is generally curved.The flabellum width of fan
There is design with angle, to see depending on the load power of motor, if only seeing that rotating speed is certain discounting for power of motor, more
See the angle of flabellum, if the same certainly flabellum of the angle of flabellum it is wide wind it is big.And the design and making of flabellum are all in
It is now the symmetrical structure of systematicness, can like this generates the wind regime of uniform stabilization.Common are valve has three valves, and four
Valve, five leaves fan, double layer sash etc., the flabellum of existing fan generally includes a wheel hub and is outwards integrally extended by the outer peripheral edge of wheel hub
Several blades.Blade is usually obliquely installed clockwise or counterclockwise, is made an uproar with improving the wind sweeping area of blade and reduction
Sound and other effects.However, since the wheel hub of existing flabellum is integrally formed with blade, the need that blade is rotated along single direction can only be met
It asks, when changing blade lean direction to adapt to different demands, in addition die sinking is also needed to make, cost is higher, and present
Flabellum sharp edges, flabellum material is harder, once using accidentally, being easy to damage human body, danger is very high.For this purpose,
It is proposed that a kind of flexibility flabellum.
Utility model content
The main purpose of the utility model is that a kind of flexible flabellum is provided, by being equipped with card wire, card wire in blade surface
The earth magnetism magnetic line of force can be cut when flabellum is blown towards east-west direction, so that card wire both ends generate certain electrical potential difference, make card wire
Needle point on assemble a small amount of charge, have to the micronic dust in air and harmful macromolecular and adsorb and ionization decomposition so that
For flabellum in air event is promoted, air laterally slips over blade surface, is then sent out forward, this will be in the process since air will flow
Card wire through blade surface, therefore original block-like air will be combed segmentation by card wire, form tiny fragment group, thus become
Soft temperature is soft, and user is made to feel more comfortable happy.By being surrounded by frame in blade, can prevent the edge of flexible blade because by
Power is excessive and deforms upon, and generates pressure release phenomenon, ensure that the turning power on motor can be smoothly transferred on fan leaf.Pass through
Equipped with blade made of polypropylene and glass fiber compound material, flexible blade can be according to the fluid force side itself being subject to
To difference, the radian of adjust automatically cambered surface makes the cambered surface of blade and the flow curve of fluid preferably coordinate, so as to alleviate
The turbulent flow phenomenon of fluid reduces the mutual impact between fluid, the noise that flabellum generates when running is greatly lowered, but also
The own wt of flabellum is alleviated, can effectively be solved the problems, such as in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of flexibility flabellum, including revolving bed, axis hole, blade, card wire and metal derby, the revolving bed centre of surface position
Equipped with axis hole, the axis hole one side is equipped with mounting hole, is equipped with metal derby in the revolving bed, the revolving bed one side is fixedly connected
Blade, the blade surface are equipped with card wire, and the blade one side is equipped with frame, and the blade is equipped with rectangle with frame junction
Slot.
Further, the blade particular number is provided with three groups.
Further, the card wire is card wire made of metal material.
Further, the frame is coated on blade surrounding.
Further, the frame is frame made of ABS plastic material.
Compared with prior art, the utility model has the advantages that：
1st, by being equipped with card wire in blade surface, card wire can cut earth magnetism magnetic force when electric fan is blown towards east-west direction
Line so that card wire both ends generate certain electrical potential difference, makes to assemble a small amount of charge on the needle point of card wire, to the micronic dust in air with
And harmful macromolecular has absorption and ionization decomposition so that for flabellum in air event is promoted, air laterally slips over flabellum
Then surface is sent out forward, in the process since air will flow through the card wire of blade surface, original block-like air will for this
It is combed and splits by card wire, form tiny fragment group, it is soft thus to become soft temperature, makes user's sensation more comfortable happy.
2nd, it by being surrounded by frame in blade, can prevent the edge of flexible blade from being deformed upon due to stress is excessive, produce
Raw pressure release phenomenon, ensure that the turning power on motor can be smoothly transferred on fan leaf.
3rd, by being equipped with blade made of polypropylene and glass fiber compound material, flexible blade can be subject to according to itself
Fluid matasomatism force direction difference, the radian of adjust automatically cambered surface, make blade cambered surface and fluid flow curve it is preferable
Cooperation, so as to alleviate the turbulent flow phenomenon of fluid, reduces the mutual impact between fluid, makes the noise that flabellum generates when running big
Amplitude reduction, and also reduce the own wt of flabellum.
