Title:
TEMPERATURE MEASUREMENT SYSTEM FOR HEAT-NOT-BURN CIGARETTE, AND TEMPERATURE MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2024/037519
Kind Code:
A1
Abstract:
A temperature measurement system for a heat-not-burn cigarette (1), and a temperature measurement method. The system comprises a high-frequency electromagnetic wave heating device (2) used for heating an aerosol generation section of the cigarette (1), and a temperature measurement device (3). The temperature measurement device (3) comprises: a light source portion (31) used for generating pulsed light; a light transmission portion (32) connected to the light source portion (31) and used for receiving and transmitting the pulsed light; a probe (33) provided at the end of the light transmission portion (32) distant from the light source portion (31), a fluorescent material (34) being provided on the end surface of the probe (33) inserted into the cigarette (1), and the fluorescent material (34) receiving the pulsed light and being excited by the pulsed light to generate a fluorescent signal; and a detection portion (35) used for receiving the fluorescent signal and obtaining the temperature inside the cigarette (1) on the basis of the fluorescent signal. The temperature measurement system for the heat-not-burn cigarette (1) and the temperature measurement method allow for measurement of the heating temperature of the heat-not-burn cigarette (1) in a strong magnetic field environment, and the measurement result is more accurate.
