[0035] A transmission mechanism is provided on the top of the electric heating body, and the induced draft component and the heating tube 2 are respectively connected to the transmission mechanism. When the induced draft component is running, the transmission mechanism can drive the fins 3 on the heating tube 2 to swing back and forth to increase the contact area between the fins 3 and the flowing air and guide the wind direction.

[0036] In this solution, the rate at which ambient air passes through the electric heating body can be accelerated under the action of the induced draft component, so that the air can circulate better. At the same time, the transmission mechanism will cooperate with the induced draft component to drive the fins 3 on the heating tube 2 to swing back and forth, so that the contact area between the fins 3 and the flowing air is increased and the wind direction is swung to guide.

[0050] As a further solution of the utility model, the outer wall of the housing 1 is provided with a fixing seat 22, and a rotating column 23 is rotatably provided on the fixing seat 22;

[0051] One end of the rotating column 23 is fixedly connected to the output end of the motor 18 . A second bevel gear 24 is disposed on the outer wall of the rotating column 23 . The second bevel gear 24 and the first bevel gear 11 are meshed with each other.

[0052] In this embodiment, since one end of the rotating column 23 is fixedly connected to the output end of the motor 18, the rotating column 23 will rotate along with the output end of the motor 18, and the rotating column 23 will drive the second bevel gear 24 to rotate during the rotation process;
