AI Technical Summary

Technical Problem

The prior art is difficult to accurately detect the internal temperature field of the heating cigarette without breaking and invading the heating cigarette, especially under electromagnetic and infrared heating methods, the positioning of the temperature measuring tool is inaccurate and susceptible to electromagnetic field interference.

Method used

The pre-arranged actual heating smoke and reference heating smoke are used to measure the temperature in real time on its outer surface and the exposed end of the cigarette through a non-contact temperature measuring device. The internal temperature distribution of the cigarette is calculated using the temperature difference, and combined with the smoker and the calculation unit. Data processing to generate a temperature dynamic cloud map.

Benefits of technology

It realizes the accurate detection of the dynamic distribution of the internal temperature field of the heating cigarette without destroying the structure of the heating cigarette, avoiding inaccurate positioning of the temperature measuring tool and interference from the electromagnetic field, and improving the accuracy and simplicity of measurement.

Abstract

The invention provides a dynamic detection method and system for internal temperature distribution of a heated cigarette, and relates to the technical field of cigarette burning and smoking index detection.The method comprises the steps that an actual measurement heating smoking set and a reference heating smoking set which are arranged in a set temperature measurement area in advance are used for heating an actual measurement cigarette and a reference cigarette clamped by the actual measurement heating smoking set and the reference heating smoking set respectively; wherein the actually measured heating smoking set and the reference heating smoking set adopt heating smoking sets of the same model, and the material of the reference cigarette has thermal stability within the heating temperature range of the heating smoking sets; smoking the actually measured cigarette and the reference cigarette by using a smoking machine; performing real-time temperature measurement on the actual measurement heating smoking set, the reference heating smoking set and the exposed ends of the actual measurement cigarette and the reference cigarette by using a non-contact temperature measurement device to obtain temperature data; and according to the temperature data, obtaining an actually measured dynamic cloud picture of the internal temperature of the cigarette. The internal temperature field of the heated cigarette in the heating process can be detected under the condition that the heating smoking set is not broken or intruded.
