By taking Fig. 2 preferred embodiment as an example, the concrete operating principle of tower fan oscillating mechanism and tower fan of the present utility model
It is as follows：The other components of electric machine support 104 and fuselage 200 are combined by connected modes such as screw, buckles, whole
An entirety can be regarded in individual motion process as, the part is the unitary rotation during shaking the head.Drive device 103 is (with stepping
Exemplified by motor) be fixed on electric machine support 104, first gear 101 is installed on step motor shaft, shaft element 107 also by
Screw is connected with electric machine support 104.When stepper motor is rotated by certain direction, phase is also pressed together with first gear 101
Equidirectional rotation, because first gear 101 (as driving gear) and second gear 102 (ring gear, as driven gear) are nibbled
Close (meshing condition is known content, and this is repeated no more), between the two i.e. can relative motion, due to shaft element 107 this zero
The presence of part, actual conditions are that base 100 (namely second gear 102) is motionless, and the effect showed is that base 100 is motionless,
The rotation direction of fuselage 200 and stepper motor when stepper motor goes to certain angle according to standard or demand on the contrary, (set
Angle), stepper motor reversion, fuselage 200 is inverted running, is that the reversing work of shaking the head of fuselage 200 can be achieved by above-mentioned action
Energy.Because the assembling of gear need not consider direction, compared to the crank and rocker mechanism of prior art, Assembly part is reduced, can be with
Greatly improve efficiency of assembling.
Simultaneously as the presence of rolling element 105, the first raceway 1041 and the second raceway 1021 can also smear the silicon of lubrication
Fatty oil, it thereby may be ensured that more steady when fuselage 200 is shaken the head.
When external force of the fuselage 200 by a direction (such as horizontal direction), fuselage 200 will certainly be in the presence of external force
Tilted along the direction of the external force, fuselage 200 produces extruding to rolling element 105, due to the rigidity characteristics of rolling element 105, rolling element
105 elastic deformation is smaller, therefore inclined angle can be accordingly smaller, and the complete machine showed is rocked also just small.
Oscillating mechanism of the present utility model can realize the commutation function of shaking the head of tower fan, and Assembly part is few, is greatly improved
Efficiency of assembling；Simultaneously as the presence of rolling element, can greatly reduce rocking for complete machine.Therefore, oscillating mechanism of the present utility model
It can realize that tower fan steadily commutates after moving and when moving, reduction is rocked, and improves Consumer's Experience, and lifting user is recognized product
Can.In addition, substituting conventional crank and rocker mechanism with gear mechanism, efficiency of assembling is improved, is solved the problems, such as easily stuck.
For those skilled in the art it is easily understood that on the premise of not conflicting, above-mentioned each preferred scheme can be free
Ground combination, superposition.
It should be appreciated that above-mentioned embodiment is only illustrative, and not restrictive, without departing from of the present utility model
In the case of general principle, those skilled in the art can be directed to the various obvious or equivalent modification that above-mentioned details is made
Or replace, all it is included in right of the present utility model.
