Abrégé

Disclosed are a non-contact e-cigarette heater, and a heating control method and control device for a ceramic heating body (10). The ceramic heating body (10) comprises a heating body (11) and a heating circuit (12), wherein the heating body (11) is of a column shape, a porous channel (101) is provided in the heating body (11), and the heating circuit (12) is arranged on the heating body (11) so as to heat air passing through the porous channel (101). The heating control method comprises the following steps: when a non-contact e-cigarette heater is started, controlling a heating circuit (12) to perform a heating operation by using a first operating voltage, and timing an operating time of the heating circuit (12); detecting an operating current of the heating circuit (12); and performing, according to the operating time of the heating circuit (12) and the operating current of the heating circuit (12), depressurization control on the operating voltage of the heating circuit (12). By controlling the operating voltage of the heating circuit (12), the effect of air heating required for smoking can be achieved, dynamic power compensation is not required, and temperature control is not required, thereby not only simplifying the complexity of control, but also achieving a better control response effect.
