The output end of the gear set is meshed with the rack 34, namely, the motor 33 drives the gear set to rotate, so that the whole heating element is driven to move along the length direction of the rack 34. The controller is used for controlling the start and stop of the motor 33 so that the heating element can be used for baking the cut tobacco segments of the cigarettes 9 in a segmented mode. For example, the motor 33 is controlled in a timing manner by the controller, and when the heating element is baked for a set time, the motor 33 drives the heating element to move to the next position to continue baking.

Specifically, the first accommodating cavity is internally provided with an air flow sensor, the air flow sensor is used for detecting the air flow in the first accommodating cavity, and the air flow sensor is electrically connected with the controller. The gas flow rate is detected by the gas flow sensor, and the number of times the user sucks the cigarette 9 is calculated by using the detection data. And then controls the motor 33 to operate according to the sucking times. For example, the cut tobacco segments of the cigarette 9 are divided into a plurality of segments, and smoke generated by heating one segment can be sucked for N times, and when the smoke exceeds N times, tobacco components in the smoke are reduced, so that the sucking taste is affected. Therefore, through the inspection data of the airflow sensor, after the user absorbs N times, the motor 33 can be controlled to work, so that the motor 33 drives the heating piece to move to the next section for heating and baking, the lasting consistency of the taste absorbed by the user is ensured, and the experience effect is improved.
