At this time, the second rotating shaft 260 will rotate counterclockwise again under the action of the torsion spring and return to the initial position (as shown in the attached figure). Figure 4 Then the lever 390 abuts against the second baffle 370 again, and the cycle repeats, thereby driving the hair dryer 250 to swing back and forth.

[0035] The overhead cable ice-melting transformer also includes a temperature sensor, a controller, and a battery. The temperature sensor is located at the top of the housing 110. The battery is used to power the temperature sensor, the controller (e.g., a single-chip microcomputer), the first motor 340, the second motor 470, the third motor 430, and the resistance heating wire 440. The controller is used to obtain the real-time temperature value collected by the temperature sensor. When the real-time temperature value falls below a preset value (e.g., 3°C, which is prone to ice formation), the controller controls the second motor 470, the third motor 430, and the resistance heating wire 440 to start synchronously, and controls the first motor 340 to start. The controller also controls the first motor 340 to switch direction at preset intervals, thereby causing the lifting arm 230 to reciprocate. Specifically, the preset duration is the time it takes for the lifting arm 230 to move from a high position to a low position (or vice versa) (e.g., 3 seconds).
