By the transmission of a turbine worm mechanism, the mechanism is more compact, the meshed carrying capacity is large, the transmission is stable, and the noise is low.
Description
Technical field
The utility model relates to a kind of fan, and especially relating to a kind of manpower that do not need promptly can the moving electronic fan of Automatic fan.
Background technique
People use electric fan more now, but the moulding of electric fan is limited, and are not attractive in appearance, and make the people not have the sensation of natural wind.In addition, the rotational velocity of electric fan is very fast, hurts sb.'s feelings easily.The common fan of agitating uses graceful, has represented a kind of taste and trend of life, yet has wasted time and energy, and is difficult to carry out other motions when shaking fan, comparatively wastes time.Given this, provide a kind of existing life taste, again can be time saving and energy saving, comfortable nice and cool being necessary from the movable pendulum fan utmost point.
The model utility content
The purpose of this utility model provides a kind of fan that can agitate automatically, and can fold, and it is easy to carry, and beautiful shape, moulding uniqueness, can swing governing speed automatically, can also build the comfortable living environment of a kind of elegance to Environmental Conditions, have extraordinary practicability.
For achieving the above object, provide following technological means.
A kind of electronic fan has the covering of the fan of agitating, and comprises pedestal, motor, worm screw, turbine, first connecting rod dish, second connecting rod and third connecting rod.Described pedestal, it supports described covering of the fan; Described motor, it is installed in the pedestal; Described worm screw, it is installed on the described motor shaft; Described turbine, itself and described worm meshing transmission, and have the turbine gear concentric with turbine; Described first connecting rod dish, it is can be around the gear disk of the axle rotation that is installed on pedestal, this gear disk and described turbine meshed transmission gear; Described second connecting rod, it is connected with the eccentric part hinge of described first connecting rod dish at the first connecting rod dish; Described third connecting rod, the one end can be around the axle rotation that is installed on pedestal, and the other end is connected with described second connecting rod hinge; Described covering of the fan moves with described third connecting rod.
The utility model is agitated by the driven by motor covering of the fan, is convenient to speed governing and changes.In addition,, can obtain very big velocity ratio by the turbine and worm mechanism driving, more compact with the crossed helical gears driving mechanism, be positioned over and save the space in the pedestal.In addition, be the line contact between the two-wheeled mesh tooth face, its bearing capacity is much higher than crossed helical gears mechanism.Worm drive is equivalent to power screw, is multiple tooth engagement driving, so stable drive, noise are very little, uses the motor driven fan period of the day from 11 p.m. to 1 a.m can not produce too big noise, is suitable for the various occasions that need peace and quiet and uses.Also have, turbine and worm mechanism has self-locking performance, and when the angle of lead of worm screw during less than the equivalent friction angle of meshing wheel between cog, mechanism has self-locking performance, can realize reverse self-locking, and covering of the fan rocks when promptly having avoided motor motionless.Can to move forward into row before and after can be on third connecting rod 43 by fan seat not folding the time spent for fan.
Description of drawings
Fig. 1 is the schematic representation according to an embodiment's of the present utility model electronic fan; And
Fig. 2 is the schematic representation after folding according to an embodiment's of the present utility model electronic fan.
Embodiment
Fig. 1 shows the electronic fan according to a preferred embodiment of the present utility model, and it comprises that swing gives birth to the covering of the fan 5 of wind, and supports covering of the fan 5 to wait the pedestal 11 of all parts, also has the cover 12 supporting with pedestal 11.
Electronic fan of the present utility model adopts motor 2 as power source, and motor 2 is installed in the pedestal 11.The worm screw 31 that the axle of motor 11 connects turbine and worm mechanism spreads out of power, worm screw 31 and turbine 32 engagement driving.Turbine 32 also has coaxial turbine gear 321, when turbine 32 rotates, and first connecting rod dish 41 engagement driving of turbine gear 321 and quadratic crank mechanism.
This first connecting rod dish 41 is the cogged disk of marginal zone, it is installed on pedestal 11, can rotate around the axis, and is connected with second connecting rod 42 by hinge at the disk eccentric part, therefore when turbine 32 drove 41 rotations of first connecting rod dish by gear engagement, quadratic crank mechanism promptly started.
The axle of third connecting rod 43 also is installed on the pedestal, and second connecting rod 42 is connected with third connecting rod 32 hinges, and when first connecting rod dish 41 carried out circular movement, quadratic crank mechanism was converted into swinging back and forth of third connecting rod 43 with the circular movement of first connecting rod dish 41.
The fan seat 51 of fixing covering of the fan 5 is installed on the third connecting rod 43, so swinging back and forth of third connecting rod 43 change swinging back and forth of covering of the fan 5 into, has finally realized the electronic fan of oscillating-type.
Have a waist hole on third connecting rod 43, add shock mount in the hole, fan seat 51 is connected with third connecting rod 43 hinges, and the axle of hinge is positioned at this waist hole, and this axle can front and back activity in the waist hole, finishes the action of normally opening and folding.Covering of the fan 5 can move forward and backward folding by fan seat 51 on third connecting rod 43.
