Abstract
The utility model relates to a folding-blade fan consisting of a rotating plate, fan blades, springs, slide ways, a fixed shaft and movable pulleys, wherein the rotating plate serves as a connecting part and a driving part for a motor and the fan blades and can be made into various shapes according to the shape of the whole fan. The fan blades are hinged with the rotating plate and provided with the slide ways for fixing the movable pulleys. The springs are arranged between the fan blades and the rotating plate, with one end fixed on the rotating plate and the other end connected with one of the slide ways on the fan blades, for providing pulling power during the folding and unfolding process of the fan blades. During the use of the utility model, the fan blade unfolds at different angles according to different rotating speed, thereby generating wind in directions. The fan blades can be folded so as to prevent dust forming depositing on the fan blades when the fan is not used. The change in the unfolding angle of the fan blades provides the fan different shapes, thereby easily realizing the combined functions of practicality, multi-function, interests and decoration.
Description
Technical field:
The utility model relates to fan, relates in particular to the flexible wing fan.
Background technique:
At present commercially available various fans rotate under the drive of rotating disc for the fan wing is fixed on the rotating disc.This layout makes the wind direction of fan single, and the fan wing is piled up dust easily under not commentaries on classics of the fan state, has limited the performance of fan functionality to a certain extent, has also limited the development in the fan moulding.
The model utility content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of flexible wing fan is provided, and both can bring into play the function of prior art fan, can further excavate the extension function and the space design of fan again.
Flexible wing fan described in the utility model includes the fan wing, rotating disc, stationary axle, spring, movable pulley and sliding rail and forms.Said rotating disc is a main component of the present utility model, and rotating disc is again link and the driving component that connects the motor and the fan wing, and rotating disc can be made different shapes to adapt to the moulding needs of whole fan.The fan wing and rotating disc that flexible wing fan described in the utility model relates to are hinged, have on the fan wing can limit slippage the sliding rail of wheel, the purpose that sliding rail is set is to make the fan wing even in the force variation of folding and expansion process medi-spring, and amplitude of variation is not too large.The spring that the utility model relates to is the associate member of fan, and said spring is installed between the fan wing and the rotating disc.One end of spring is fixed on the rotating disc, and the other end of spring is connected with sliding rail on the fan wing by movable pulley, provides folding pulling force in the folding or expansion process of the fan wing.
Working principle of the present utility model is: when fan was not worked, the fan wing was folded up under the effect of spring tension; When fan rotated, the fan wing launched gradually under the acting in conjunction of centrifugal force that the fan wing rotate to produce and spring tension, and along with the different fan wings of rotating speed are different start points.
Usefulness of the present utility model is: in use because the angle that the different fan spanes of rotating speed are opened is also different, thereby can produce the wind of different direction.The fan wing of folding up can be avoided fan superincumbent accumulation of dust under user mode not.The variability of the start point of the fan wing gives fan different moulding again.Practicability, multifunctionality, interest and the ornamental combination of fan have easily been realized.
Description of drawings:
Embodiment:
Referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows in conjunction with the embodiments: flexible wing fan described in the utility model includes rotating disc 1, sliding rail 2, the fan wing 3, movable pulley 4, spring 5 and stationary axle 6 and forms.Said rotating disc 1 is a main component of the present utility model, and rotating disc 1 is again link and the driving component that connects the motor and the fan wing 3, and rotating disc 1 can be made different shapes to adapt to the moulding needs of whole fan.The fan wing 3 that flexible wing fan described in the utility model relates to is hinged with rotating disc 1, have on the fan wing 3 can limit slippage the sliding rail 2 of wheel 4, the purpose that sliding rail 2 is set is to make the fan wing 3 even in the force variation of folding and expansion process medi-spring 5, and amplitude of variation is not too large.Also can say so, the fan wing 3 is hinged with rotating disc 1, and the fan wing 3 is provided with fixedly movable pulley 4 and can guarantees the force variation uniform sliding rail 2 of the fan wing 3 at folding and expansion process medi-spring 5, and amplitude of variation is not too large.The said spring 5 of the utility model is the associate member of fan, and said spring 5 is installed between the fan wing 3 and the rotating disc 1.One end of spring 5 is fixed on the rotating disc 1, and the other end of spring 5 is connected with sliding rail 2 on the fan wing 3 by movable pulley 4, the fan wing 3 fold or expansion process in folding pulling force is provided.Working principle of the present utility model is: when fan was not worked, the fan wing 3 was folded up under the effect of spring 5 pulling force; When fan rotates, rotate at the fan wing 3 that the fan wing 3 launches gradually under the acting in conjunction of the centrifugal force that produces and spring 5 pulling force, and along with the different fan wings 3 of rotating speed are different start points.Usefulness of the present utility model is: in use because the angle that the different fan wings 3 of rotating speed launch is also different, thereby can produce the wind of different direction.The fan wing of folding up 3 can be avoided fan superincumbent accumulation of dust under user mode not.The variability of the start point of the fan wing 3 gives fan different moulding again, has easily realized practicability, multifunctionality, interest and the ornamental combination of fan.
