1Stability of the object's composition
If circumferential heating or central heating element is used for heating the cigarette, then the cigarette can be heated evenly, but heat accumulates in the smoke due to poor air circulation causing mouth burning
Solution Approach 1:
The cigarette is divided into multiple heating segments (first heating segment, second heating segment, etc.) along its length. Each segment is heated independently with different heating temperatures, allowing precise control of temperature distribution to prevent heat accumulation at the mouth end while ensuring even heating throughout the cigarette body.
Solution Approach 2:
Different heating temperatures are applied to different segments of the cigarette. The first heating segment (closer to the mouth) uses a lower heating temperature, while the second heating segment (farther from the mouth) uses a higher heating temperature. This local differentiation ensures uniform smoke temperature and prevents mouth burning.
2Device complexity
If uniform heating temperature is applied to the entire cigarette, then the heating process is simple, but the temperature of vaped smoke becomes uneven causing discomfort
Solution Approach 1:
The heating temperatures of different cigarette segments are dynamically adjusted based on real-time temperature detection. The detection unit monitors temperatures at various positions, and the processing unit continuously optimizes heating temperatures for each segment to maintain uniform smoke temperature, adapting to changing conditions during vaping.
Solution Approach 2:
A detection unit is positioned to detect the temperature of the cigarette or smoke in real-time. This temperature information is fed back to the processing unit, which adjusts the heating temperatures of different segments accordingly, creating a closed-loop control system that ensures uniform smoke temperature.

AI summary
A segmented heating temperature control method and apparatus for an electronic vaping set, and an electronic device. The method comprises: acquiring vaping set parameter information, and dividing into at least two e-cigarette heating segments on the basis of the vaping set parameter information (S101); determining an initial heating temperature of a vaping set, and constructing a neural convolutional network model according to the initial heating temperature of the vaping set, so as to calculate a first temperature change curve of each e-cigarette heating segment under a preset suction condition (S102); and on the basis of the first temperature change curve, separately adjusting the initial heating temperature corresponding to each e-cigarette heating segment to obtain each adjusted heating temperature, so that the temperature range of a second temperature change curve corresponding to each adjusted heating temperature is within a preset range (S103). The interior of the vaping set is divided into several e-cigarette heating segments, and by simulating and adjusting the temperature change of each e-cigarette heating segment in the vaping set vaping process under a certain vaping condition, the temperature corresponding to the finally vaped vapor being relatively balanced is ensured, and mouth-burning is prevented from occurring when a user is vaping.
