Abstract

The utility model relates to a turning angle controller for an oscillation electric fan. A fixed end of an oscillation connecting rod is hinged with a pivot shaft whose position is changeable, and namely the angle of oscillation is between 30 DEG and 90 DEG with a continuously variable effect. The utility model has the advantages of simple structure, easy manufacture, function addition, and energy saving. The utility model can be manufactured in enormous quantities as a new design, and can be used for reforming existing oscillation electric fans with fixed angles.

Description

The electric fan angle controller of shaking the head

The utility model relates to a kind of control gear of electric fan oscillating angle.

The existing electric fan of shaking the head, as desk fan, stand fan, wall fan the similar oscillating mechanism of one cover is arranged all: its fan motor housing all is to be hinged on the mounting by waving vertical shaft, the drive pinion shaft and the passive gearwheel that drive after the worm and worm gear device slows down are housed in the motor field frame, under the gearwheel cam pin is arranged, article one, make an end and the cam pin of the connecting rod that motor body waves hinged, the other end of connecting rod is hinged on fixing little that waves the vertical shaft next door on the mounting.When motor reel rotates, the rotation of drive worm and worm wheel, when if the engaging and disengaging gear of worm-wheel shaft is in jointing state, worm-wheel shaft will drive the drive pinion shaft rotation, thereby drive the gearwheel rotation,, can't move owing to be hinged on the fixing mounting with the other end of cam pin articulated linkage under the gearwheel, thereby the motor field frame itself that has gearwheel has been changeed around waving vertical shaft, its rotation angle generally is about 90 °.If the engaging and disengaging gear on the worm-wheel shaft is in separated state, worm-wheel shaft just can't be with transmission of power to pinion shaft, thereby small gear and gearwheel do not rotate, and motor field frame (fan head) also just can't wave.The panning angle of this electric fan or be 90 °, or be 0.This feels inconvenience very much for using, and also is unfavorable for energy-conservation.

Task of the present utility model is to provide a kind of structure foolproof electric fan oscillating angle controller, and it can make the panning angle of electric fan adjustable continuously in 30 °～90 ° scope.

Task of the present utility model is finished like this: fixed end and the changeable pivot knuckles in position that shake the head connecting rod and the mounting of existing electric fan is hinged get final product.That is to say, in the utility model, be hinged on and also be equipped with in the motor field frame on the mounting by waving vertical shaft through worm and worm gear device the slow down drive pinion shaft and the passive gearwheel of back drive, cam pin is also arranged under the gearwheel, one end and the cam pin of connecting rod are hinged, but the other end and the changeable pivot knuckles in position.

Pivot can be fixed on one and have in the guide rail of sliding poor or guide rod, also can be arranged on an end of a fork, the middle part of this fork or the other end and mounting are hinged, but this articulating point should be slightly larger than the beeline of cam pin to the vertical shaft shaft axis to the distance of variable pivot axis line, go out to hold or the middle part second month in a season with flexible axle, screw rod even people's hand propulsion fork, can make the pivot pin end of fork change the position, thereby the panning angle of electric fan is changed.

In fact, the utility model can make the panning angle of electric fan adjustable continuously in 0 °～90 ° scope, but use was both not too convenient in 0 °～30 ° scopes, did not also have much practical significances, thereby taked can be adjusted in 30 °～90 ° scopes good.

Because the utility model only is an end Placement that changes a connecting rod of original electric fan of shaking the head, to fixedly become adjustable, thereby it is not only simple in structure, making or reforming cost are low, both be convenient to improve design, produced in batches, also be convenient to transform the existing electric fan of shaking the head, made it to have the adjustable kinetic energy of corner, simultaneously can reach certain energy-saving effect, avoid the waste of wind.

Below describe with embodiment and accompanying drawing.

Fig. 1 is a kind of schematic representation that has the electric fan of shaking the head of manual tune fork rotary corner controller that derives from design according to the utility model.Fig. 2 is the sectional view along A-A line among Fig. 1, and Fig. 3 has soft cover steel core wire to regulate the schematic representation of the rotary corner controller of fork, and Fig. 4 has the schematic representation of regulating the sliding rotary corner controller that is pickled with grains or in wine, and Fig. 5 is the schematic representation that the corner control of adjusting screw rod is arranged.

Referring to accompanying

drawing

1 and 2, the vertical shaft 2 of electric fan mounting 1 front end and the preceding lower hinge of motor field frame 3.The worm and worm gear speed reducer 4 that is driven by motor main shaft is equipped with at the motor case rear portion, and its worm-wheel shaft connects with drive pinion shaft 5 through engaging and disengaging gear.Be extended with cam pin 7 with gearwheel 6 lower end surfaces of pinion shaft 5 engagements.The right-hand member of connecting rod 8 and cam pin 7 are hinged, the changeable pivot in left end and position 9 is hinged, this pivot is arranged on the left end of vertical fork 10 near vertical shaft 2, and the mounting position of the middle right part of fork 10 and cam pin 7 belows is hinged, and the right-hand member of fork is as the position of handle in order to adjusting pivot 9.Stir fork along clockwise direction, make pivot 9 near vertical shaft 2, it is big that the panning angle of electric fan just becomes, and when counterclockwise stirring fork, makes pivot 9 become estranged vertical shaft 2, and the panning angle of electric fan just diminishes, and this angle can be regulated in 30 °～90 ° scope continuously.In Fig. 3, the right-hand member of fork 10 and mounting 1 are hinged, are connected with the soft cover steel core wire 11 that is fixed on the mounting relevant position between two rounded ends of fork, and the control end of steel core wire can be arranged on the electric fan control panel.Tension steel core wire 11 can make fork 10 rotate in the counterclockwise direction, makes pivot 9 become estranged vertical shaft 2, to turn panning angle down; Loosen or push steel core wire 11, fork 10 clockwise directions are rotated, allow pivot 9 near vertical shafts 2, to transfer big panning angle.For the clockwise direction that makes fork 10 rotates reliably, can between fork 10 and mounting 1, return torsion spring 12 or extension spring be set.In Fig. 4, the pivot 9 hinged with connecting rod 8 left ends is arranged on the slide block 14 of a convertible position from the cunning poor 13 of vertical shaft 2 horizontal expansions.In Fig. 5, pivot 9 is arranged on the nut 16 of a convertible position from the screw rod 15 of vertical shaft horizontal expansion.Be understood that, as long as change the position of slide block 14 or nut 16, can make pivot 9 near or away from axle 2, thereby the panning angle of electric fan is changed.The foregoing description is partial design representative of the present utility model, and scope of the present utility model is not limited thereto.
