Abstract
The utility model discloses a head-shaking mechanism for a fan, and the mechanism comprises a fan motor, a head-shaking driving disc, a head-shaking pedestal, a swinging rod, and a crank seat. The crank seat is fixed on the head-shaking pedestal, and is provided with a first vertical shaft and a second vertical shaft. The head-shaking driving disc is provided with a third vertical shaft which is eccentrically disposed on the head-shaking driving disc. The fan motor is disposed above the head-shaking pedestal in a swinging manner through the first vertical shaft. One end of the swinging rod is connected with the second vertical shaft, and the other end of the swinging rod is connected with the third vertical shaft. The mechanism is characterized in that the tail of the fan motor is fixedly equipped with a head-shaking motor; the head-shaking driving disc is connected to a motor shaft of the head-shaking motor; the head-shaking pedestal is provided with an optoelectronic switch; and the optoelectronic switch is disposed to be opposite to the swinging rod. Compared with a conventional fan, the mechanism is simple in structure, and the head-shaking angle of the fan is random and adjustable.
Description
[technical field]
The utility model relates to a kind of fan, is specifically related to a kind of oscillating head mechanism of fan.
[background technique]
Conventional fan has yaw function, when fan electromotor is worked, not only driving electric fan to rotate blows, the power of fan electromotor drives yaw drive plate to rotate after slowing down by speed reducer simultaneously, and then drive fan to carry out yaw action, so the swaying angle of conventional fan after design is fixing non-adjustable, yaw speed also can only decide according to the rotational velocity of fan electromotor, and this obviously can not finely meet the usage requirement of fan.Although also there are now some technology to improve conventional fan, its yaw action is accomplished arbitrarily controlled, structure relative complex, can not carry out practice and extension, so also seen in the market Related product, does not occur.
[summary of the invention]
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to be to provide a kind of conventional fan of comparing to have fan oscillating mechanism simple in structure, any adjustable advantage of oscillating fan angle.
For solving the problems of the technologies described above, the utility model takes following technological scheme to complete:
A kind of fan oscillating mechanism, comprise fan electromotor, yaw drive plate, yaw base, fork and crank base, crank base is fixed on yaw base, crank base is provided with the first vertical pivot and the second vertical pivot, yaw drive plate is provided with the 3rd vertical pivot, the 3rd vertical pivot eccentric setting on yaw drive plate, fan electromotor is by the swingable setting above yaw base of the first vertical pivot, described fork one end is connected with the second vertical pivot, the other end is connected with the 3rd vertical pivot, it is characterized in that: the afterbody of described fan electromotor is installed with yaw motor, described yaw drive plate is connected on the motor shaft of yaw motor, on described yaw base, optoelectronic switch is installed, optoelectronic switch is facing to fork setting.The output of described optoelectronic switch is electrically connected to the time relay and switch power.
The fan oscillating mechanism that adopts technique scheme has carried out few change of trying one's best on the basis of conventional fan, makes it compare conventional fan and has advantages of that simple in structure, oscillating fan angle is any adjustable.Working principle of the present utility model is: yaw moves by special yaw Electric Machine Control, and yaw motor replaces the gearbox structure of fourth conventional fan, and so, the action of the yaw of fan has just departed from and the contacting of fan electromotor; Then, when yaw machine operation, fan carry out yaw action, fork can swing accordingly, monitor the initial position of fork and time Control yaw motor to the duration of oscillation of a direction, thereby it is adjustable arbitrarily to realize oscillating fan angle by optoelectronic switch.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing, each details of the utility model specific embodiment is described further:
As shown in the figure, fan oscillating mechanism of the present utility model, comprise fan electromotor 1, yaw motor 3, yaw drive plate 5, yaw base 10, fork 11 and crank base 9, crank base 9 is fixed on yaw base 10, crank base 9 is provided with the first vertical pivot 7 and the second vertical pivot 8, yaw drive plate 5 is provided with the 3rd vertical pivot 6, the 3rd vertical pivot 6 eccentric setting on yaw drive plate 5, fan electromotor 1 is by the swingable setting above yaw base 9 of the first vertical pivot 7, described fork 11 one end are connected with the second vertical pivot 8, the other end is connected with the 3rd vertical pivot 6, by supporting plate 2, the afterbody at fan electromotor 1 fixedly mounts described yaw motor 3, described yaw drive plate 5 is connected on the motor shaft 4 of yaw motor, on described yaw base 10, optoelectronic switch 12 is installed, optoelectronic switch 12 is the initial position before swing and arranging facing to fork 11, the output of described optoelectronic switch 12 is electrically connected to the time relay 13 and switch power 14.
Working principle of the present utility model is: during fan electromotor 1 work, drive electric fan to rotate and blow, and drive fan to carry out yaw action during yaw motor 3 work, when fan is done yaw action, fork 11 can swing accordingly, initial position and the time relay 13 by optoelectronic switch 12 monitoring forks 11 are controlled yaw motor 3 durations of oscillation to a direction, just can realize the adjustable arbitrarily of oscillating fan angle, when the time that the time relay arranges is grown, the pendulum angle of fan is large, when time that the time relay arranges in short-term, the pendulum angle of fan is little.
