This study aims to thoroughly explore the key influencing factors of e-cigarette
atomization temperature to provide a scientific basis for e-cigarette product
development and avoid the harmful substance release caused by excessively high
atomization temperature. The fourth-generation e-cigarette was selected as the
research object, and the atomization temperature was measured using a method
based on the TCR (Temperature Coefficient of Resistance) to systematically
investigate the effects of puff topographies (puff volume, puff interval, and
puff duration), working parameters (output power and draw resistance), and
solvent ratios on atomization temperature. The results show that solvent ratio,
puff duration, power, puff interval (P<0.01), and puff
volume (P<0.05) are significant influencing factors of
atomization temperature. Puff duration and output power have positive
correlations with atomization temperature, while puff volume, puff interval, and
draw resistance have negative correlations. Regarding the solvent ratio, the
atomization temperature generally increases with the increase of VG mass
fraction in the e-liquid. This study proposes a novel method for measuring the
atomization temperature and clarifies the influence of various factors on
e-cigarette atomization temperature, analyzes the principles and degrees of
influence, and provides theoretical support for optimizing e-cigarette design
and reducing the health risks associated with excessively high atomization
temperature, which is of great significance to the healthy development of the
e-cigarette industry.
