Effect of different vaping parameters on the release of electronic cigarette

In addition to power and e-liquid, the smoke generated by electronic cigarettes is one of the key factors affecting smoke.

The fixed vaping duration is 3s, the vaping frequency is 30s, and the vaping capacity is 55mL. The effects of vaping curves such as sine wave, square wave and triangle wave on aerosol particle phase (TPM) and nicotine release were investigated. The results are shown in Table 1. When the square wave vaping the electronic cigarette, the aerosol phase particle (TPM) and nicotine release amount is slightly higher than the sine wave and the triangle wave. This may be due to the fact that the square wave vaping the electronic cigarette when the airflow rate reaches the extreme value to make the electronic cigarette effective working time. Slightly larger than the other two vaping curves, the corresponding phase emission (TPM) and nicotine release of the electronic cigarette aerosol are slightly higher than the sine wave and triangle wave vaping curve.

The fixed vaping curve is square wave, the vaping frequency is 30s, and the vaping capacity is 55mL. The effects of different vaping durations on the release of nicotine from vape aerosols under two power states are investigated. As the duration of vaping increases, the release of nicotine from the vape aerosol also increases. This may be because the duration of the vape vaping increases, and the operating temperature of the heating wire gradually rises, resulting in an increase in the release amount of the nicotine aerosol.

The fixed vaping curve is a square wave with a vaping duration of 3 s and a vaping capacity of 55 mL. The effects of different vaping frequencies on the release of nicotine from vape aerosols were investigated. As the frequency of vaping increases, the release amount of nicotine from the electronic cigarette aerosol is basically unchanged. This may be because the vape vaping interval is sufficient to restore the temperature of the vape heating wire to its original working state.

The fixed vaping curve is square wave, the vaping frequency is 30s, and the vaping duration is 3s. The effects of different vaping capacities on the release of nicotine from vape aerosols under two power states are investigated. As the vaping capacity increases, the release amount of nicotine from the electronic cigarette aerosol increases. This may be because increasing the vaping capacity increases the airflow rate of vaping, thereby increasing the amount of nicotine released by the electronic cigarette aerosol.

The experimental results show that with the increase of the power of the electronic cigarette battery, the amount of nicotine released and the TLP of the aerosol total particle phase also increase linearly, for a disposable replaceable cartridge with a fixed value of 3.1 Ω.
