Embodiment 1
[0017] like figure 1 As shown, the angle sensor-based fan head rotation angle adjustment structure of this embodiment includes a fan bracket 1 and a fan head 3 mounted on the fan bracket 1 through a rotating shaft 2 (the rotating shaft 2 can rotate on the fan bracket 1), and the fan A motor 4 is fixed on the top of the bracket 1, and the motor shaft of the motor 4 drives the rotating shaft 2 and the fan head 3 on the rotating shaft 2 to rotate through the gear pair 5; the adjustment mechanism also includes an angle sensor 6 for detecting the rotation angle of the rotating shaft 2 And a controller (not shown in the figure) with an input unit, the controller is connected with the motor 4 through a reciprocal switch to control the operation of the motor 4 .
[0018] The above-mentioned angle sensor 6 can be directly installed on the rotating shaft 2, and the rotating angle of the fan head 3 can be obtained by detecting the rotating angle of the rotating shaft 2 (the rotating shaf...
Embodiment 2
[0024] This embodiment adopts the rotation angle adjustment structure of the fan head 3 in Embodiment 1 to adjust the rotation angle of the fan head 3. The specific method is as follows: the input unit is the gear position, and different gear numbers represent different angle values; The controller controls the rotation of the motor 4, and detects the angle at which the fan head 3 turns through the angle sensor 6; The controller controls the reverse rotation of the motor 4 through the forward-reverse switch; when the gear input by the input unit is 0 gear, the controller controls the motor 4 to stop working.
[0025] In this embodiment, there are five gears in total, which are gear 0, which means that the fan head 3 does not swing; gear 1, which means that the fan head 3 swings within an angle range of 30 degrees; gear 2, which means that the fan head 3 is 30 degrees swing angle; 3 gears, fan head 3 swings at 60 degrees; 4 gears, fan head 3 swings at 90 degrees; 5 gears, fan h...
