Abstract
A kind of convergent blow fan, it is to have fixed arc wind gathering hurdle on the fan blade top, the other end is fan blade handle and gear thereof; The location control mechanism of fan blade is to be made of pedestal, flap, tooth bar group; Fan blade handle and gear thereof lay respectively in the circular hole and cavity that pedestal and flap constitute, and the tooth bar of tooth bar group is respectively in the cavity and gear engagement, and the angle of adjustable fan blade.This electric fan is by the size of the change controlled wind speed of fan blade angle; Wind gathering efficient height, wind-force is big; Noiseless; Do not need at a high speed power saving; The fore-and-aft direction of wind can change.
Description
The present invention belongs to electric fan.
No matter what use at present is electric fan, ceiling fan, or ventilating fan, generally all is made up of supporting mechanism, motor, fan blade and location control mechanism thereof.They have following common weakness, and exactly: one, fan blade is all fixed, and can not regulate wind speed with the angle of regulating fan blade, want to change the size of its wind-force, and its rotating speed only changes; Two, wind is little, not wind gathering; Three, noise is arranged.
The purpose of this invention is to provide the adjustable wind gathering electric fan of a kind of fan blade angle.It is big that it has the low wind-force of speed, noise free.
The object of the present invention is achieved like this: fixed an arc wind gathering hurdle on the top of each fan blade of electric fan, its planar development is a rectangular, and the other end is that fan blade handle and gear thereof fuse; The location control mechanism of fan blade is to be made of pedestal, flap, tooth bar group; Fan blade handle and gear thereof lay respectively at pedestal and flap and constitute in 2～4 pairs of circular holes and the cavity, and the fan blade handle is rotatable in circular hole, and 2～4 tooth bars of tooth bar group are respectively in a cavity and gear engagement, and the adjustable fan blade angle; All mechanical fixation between pedestal, flap, the tooth bar group.
The present invention has following advantage:
1. fan blade angle is adjustable, and the size of energy controlled wind speed.
2. wind-force is big, wind gathering efficient height.
3. outside 0.5 meter, can't hear noise.
4. do not need to run up power saving.
5. the fore-and-aft direction of wind is adjustable.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is a fan blade location control mechanism structural representation.
With reference to Fig. 1, Fig. 2, the supporting mechanism 1 of electric fan is supporting motor 2, the fan blade location control mechanism by screw motor 2 the axle on.The fan blade location control mechanism is made of pedestal 6, flap 7, tooth bar group 8.Pedestal 6 and flap 7 constitute 3 circular holes and 3 cavitys, and each circular hole and a cavity interlink.Between pedestal 6 and the flap 7 by screw.The blade face of 3 fan blades 3 is horizontal plane respectively, arc wind gathering hurdle 4 is all being fixed on its top, the radian on this radian and fan blade 3 tops, radian when rotating with fan blade 3 tops is consistent, arc wind gathering hurdle 4 plane outspread drawings are rectangulars, intersect vertically with fan blade 3 tops, their intersection line divides the ratio at 4 two ends, wind gathering hurdle to be respectively 3: 1 and 1: 3.The plane outspread drawing on arc wind gathering hurdle 4 also can be right-angled trapezium, and it is to intersect vertically along hypotenuse and fan blade 3 tops, and in the front of fan blade 3, the ratio at two ends of right-angled trapezium is 3: 1.The handle of 3 fan blades 3 is stuck in 3 circular holes of pedestal 6, flap 7 formations, is between fan blade handle and the circular hole and rotates contact, and 3 gears 5 just in time place three cavitys, and the diameter of gear is greater than the diameter of circular hole.3 tooth bars of tooth bar group 8 are distinguished in the hole of three difference cavity bodies on the white flaps 7, reach in the cavity to be meshed with three gears 5, and the rotation of control gear 5, thus reach the angular dimension of controlling fan blade 3, promptly control the size of wind-force.Fan blade 3 adjustable angle scopes are-65～+ 65 degree, and are calm during zero degree.During low speed, 65 degree wind reach maximum.If 0～65 degree wind direction is forward, 0～-65 degree wind direction is backward so.This electric fan will be rectangular arc wind gathering hurdle 4 with plane outspread drawing.If fan blade 3 adjustable angle scopes are 0～65 degree, at this moment needing only with plane outspread drawing has been the arc wind gathering hurdle 4 of right-angled trapezium, and this has only wind forward.Tooth bar group 8 has outside thread with flap 7, after fan blade 3 is transferred to several angle, carries out relative fixed by exterior nut cap between them.In motor 2 shell fronts, can be provided with one all over circular blade cover 9 in fan blade 3 work peripheral spaces.An oscillation controller can also be set in electric fan.
Operational circumstances is: electric fan is when being example with present low-speed running, should earlier fan blade 3 be transferred to 60～65 degree, with exterior nut cap with flap 7 and tooth bar group 8 relative fixed, connect power supply, wind was big when the wind-force before the electric fan had electric fan to run up, its wind-force is diminished, have only angle with fan blade 3 to diminish or increase, also can lower the rotating speed of electric fan again.When fan blade 3 is spent at zero degree and 90, will change the wind direction of electric fan front and back.When regulating fan blade 3 angles is when bearing the number of degrees, just can change the direction of electric fan to fore blow, and blowing backward, up to negative angle is 60～65 when spending, and to the wind maximum of after-blow, its wind-force is diminished, have only angle with fan blade 3 to diminish or increase, the rotating speed that lowers electric fan more also can be realized.
