AI Technical Summary

Technical Problem

In existing heated cigarettes, because the airflow channel on the device is downstream of the aerosol generation matrix, it is difficult to effectively record the consumer's smoking behavior, resulting in an inability to accurately obtain smoking characteristics.

Method used

A differential pressure sensor is installed inside the cigarette holder to monitor the pressure difference between the space formed by the seal, the cigarette, and the cigarette holder and the atmosphere. Combined with a data acquisition unit, a data storage unit, and a data analyzer, the consumer's smoking behavior is recorded and analyzed in real time.

Benefits of technology

It enables accurate recording of consumers' inhalation behavior in a closed aerosol generation device, and can estimate the amount of flue gas based on pressure difference changes, optimize heating process control, and improve the accuracy of data analysis and user experience.

Abstract

This invention belongs to the field of heated cigarette technology, specifically relating to an aerosol generating device, an aerosol generating system, and a method for operating the same. The aerosol generating device includes: a cigarette holder, a sealing element, a temperature controller, a differential pressure sensor, a data acquisition unit, a data storage unit, a data analyzer, and a heating element. The temperature controller is configured to adjust the output power of the heating element based on the results of the data analyzer and transmit the output power to the data storage unit. The differential pressure sensor is configured to transmit the data of its detected differential pressure change over time to the data storage unit. The data storage unit automatically receives and stores power and differential pressure data from the data acquisition unit. The data storage unit is configured to provide the data required for analysis to the data analyzer. This application enables the recording and analysis of smoking behavior data, which can be used for heating process control.
