Electronic cigarette and method for adjusting flow rate of gas flow of electronic cigarette

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.

Description

TECHNICAL FIELD[0001]The present application relates to the field of electronic products, and more particularly to an electronic cigarette and a method for adjusting flow rate of gas flow of the electronic cigarette.BACKGROUND[0002]With a rising attention to health, people come to realize the tobacco is harmful to health, thus the electronic cigarette which is both able to ease a craving for tobacco and less harmful to health is produced. The electronic cigarette is usually configured to atomize specially prepared tobacco oil and simulate tastes of smoking. When preparing the tobacco oil, materials harmful to health, such as nicotine, tar and the like, are removed to eliminate the harm to health. As the tobacco oil contains no harmful material that makes people be addicted, such as nicotine, tar and the like, the nicotine addiction will be reduced after smoking the electronic cigarette. Therefore, the electronic cigarette has an effect on assisting in quitting smoking.[0003]In the p...

AI Technical Summary

Benefits of technology

[0023]S12: blowing at the mouthpiece and generating airflow flowing backwards the mouthpiece to make a pressure inside the electronic cigarette higher than the atmospheric pressure outside, and the airflow path is sealed up by the floating sphere to avoid tobacco oil inside the atomizer flowing to the battery inside the cigarette rod.

[0024]By implementing the electronic cigarette and the method for adjusting flow rate of gas flow of the electronic cigarette of the present application, the following advantages can be achieved: by means of arranging a pressure regulating valve unit in the airflow path, it is able to control the airflow rate flowing into

Problems solved by technology

However, the airflow rate flowing into the electronic cigarette is fixed because the diameter of the intake hole is fixed, and it is difficult to adjust the amount of smoke by adjusting the airflow rate.

In addition, the tobacco oi
