Abstract
An electronic cigarette comprises a cigarette rod with a battery, an atomizer configured to atomize tobacco oil contained therein, and an airflow path configured to enable the air to flow into the atomizer. A pressure regulating valve unit arranged in the airflow path includes a floating sphere configured to close or open the airflow path according to an airflow direction and to adjust the airflow rate flowing into the airflow path. By means of arranging the pressure regulating valve, it is able to control the airflow rate flowing into the atomizer, hence adjust the amount of smoke sucked to change tastes of smoking and meet users' different needs. Moreover, when blowing to the electronic cigarette, the pressure regulating valve unit will be in a closed state to avoid tobacco oil inside the atomizer flowing to the battery and a control board.
