[0020] like Figures 1-3 As shown, an automatic heating device with adjustable duct length mainly consists of a housing 1, a fan, and a duct structure. The housing 1 has an air inlet 11 and an air outlet 12 at both ends. The fan is a conventional fan and is installed inside the housing 1 to generate hot air. A protective casing 6 is fixedly installed at the top of the housing 1. The protective casing 6 contains an automatic control system that adjusts the fan's heating power. Two retractable signal transmitting antennas 61 are symmetrically arranged on both sides of the protective casing 6. The left end of each antenna 61 is rotatably connected to the protective casing 6. In use, the antennas 61 are rotated counterclockwise to face upwards and then extended for signal reception and transmission. The automatic control system... The system consists of a conventional controller 15, a temperature sensor 16, and an AC transformer 17. The temperature sensor 16 is connected to the controller 15, and the AC transformer 17 is connected to both the fan and the controller 15. In operation, the controller 15 first receives the current signal transmitted by the temperature sensor 16, analyzes and collects the temperature information, and sends control signals to the AC transformer 17 according to the corresponding control program commands to adjust the fan's heating power and avoid ineffective heating and wasted energy. At the same time, the controller 15 sends a signal to the receiving platform of the staff via the control signal transmitting antenna 61, promptly feeding back parameters such as the temperature sensor 16 value and the AC transformer 17 power to the staff for further monitoring.
[0021] The air pipe structure is located on the air outlet 12, which comprises a corrugated pipe 2 fixedly connected with the shell 1, a receiving cylinder 21 sleeved outside the corrugated pipe 2, and a fixing assembly arranged between the receiving cylinder 21 and the shell 1.
