An electric heating device having an air channel includes an upper cover component and a lower shell component. A heater component is arranged in a lower shell of the lower shell component, and includes a heater shell, a heating member and a heating member base arranged in the heater shell. A ventilation portion is arranged at a heating member base to guide an air flow to the heating member, and is matched with a first air inlet on the lower shell and a second air inlet on the heater shell. The air flow is led to the heating member from an outside of the lower shell through the first air inlet, the second air inlet, and the ventilation in sequence.
