Rotation is on arc-shaped rack 4 to drive fan head 1 to rotate on fan head bracket 2.Oscillating fan device in the present embodiment exists
Stepper motor 3 is set on fan head bracket 2, drives gear assembly to move on arc-shaped rack 4 by stepper motor 3, thus band
The dynamic fan head 1 being similarly installed on fan head bracket 2 is rotated up and down, and realizes that fan is blown up and down.Arc-shaped rack 4 is installed
On rack gear fixed frame 5, rack gear fixed frame 5 is also installed on fan head bracket 2, and fan head bracket 2 is connected with the column of fan
It connects.
The present embodiment middle gear component includes the one-stage gear 6 being connected with 3 output shaft of stepper motor and nibbles with one-stage gear 6
The secondary gear 7 of conjunction, secondary gear 7 are meshed with arc-shaped rack 4.Gear assembly further includes stepper motor fixinig plate 8 and installation
In the gear fixinig plate 9 on stepper motor fixinig plate 8, one-stage gear 6 and stepper motor 3 are installed on stepper motor fixinig plate 8
Two sides, secondary gear 7 are installed on gear fixinig plate 9.The output axis connection of one-stage gear 6 and stepper motor 3, by stepper motor
3 drive rotation, and one-stage gear 6 drives the secondary gear 7 being meshed to rotate again, and the effect of secondary gear 7 is that speed regulation is slowed down.Due to
Secondary gear 7 is also engaged with arc-shaped rack 4, therefore secondary gear 7 is moved in arc-shaped rack 4, and motion profile is arc-shaped rack 4
Thus shape completes the transmitting of the power of rack-and-pinion, since stepper motor fixinig plate 8 is movably arranged on fan head bracket 2, when
Gear also will drive the stepper motor fixinig plate 8 fixed with gear and turn on fan head bracket 2 in arcuate movement on rack gear
Dynamic, the side of stepper motor fixinig plate 8 is fixedly connected with the side of fan head 1, and then fan head 1 also carries out upper and lower pendulum therewith
It is dynamic, realize air-supply up and down.
The shape of arc-shaped rack 4 is sector in the present embodiment, and central angle is greater than 90 degree, the fan head 1 in the present embodiment
The section swung up and down be from level to substantially vertical, therefore the central angle of arc-shaped rack 4 is slightly larger than 90 degree, restriction fan head
The central angle of 1 swing angle, certain arc-shaped rack 4 can also suitably be turned down according to use demand, the yaw of such fan head 1
Angle can be also limited in accordingly in lesser angular range.
Fan head 1 includes motor 11, the motor front housing 12 on 11 output shaft of motor, for fixing horse in the present embodiment
Up to 11 motor bracket 13 and be fixed on the resistance gear assembly 14 of 13 side of motor bracket；During resistance gear assembly 14 includes
Heart gear 141 and the reversible gear 142 engaged with central gear 141, the quantity of reversible gear 142 are two, are respectively set
Top and left part in central gear 141；It further include the left-handed shaft 15 and dextral shaft set on the corresponding two sides of motor bracket 13
16, dextral shaft 16 passes through central gear 141；Stepper motor fixinig plate 8 is fixed on the left side of motor bracket 13.Fan head 1 is used
