RUYAN?electronic Cigarette consists of some micro-electronic components such as airflow sensor, control circuit, executive circuit, high-power integrated circuit, high-frequency ultrasonic sounder, atomizing chamber mask, built-in lithium ion battery, by which it can carry out such high-tech humanized functions as airflow sensing, smoke simulation, smoke temperature simulation, standby at any moment. Meanwhile, as far as the biological technology is concerned, it can make smokers enjoy the same pleasure as that of traditional cigarette when inhaling the nicotine smog droplet, imitating the whole process of smoking. RUYAN Cigarette creates a healthy smoking cultural atmosphere, and has been eulogized by authoritative experts as the perfect combination of modern micro-electronic technology, biological technology and the conception of healthy life. In the body of RUYAN cigarette, low thickness nicotine liquid enters atomizing cell after ultramicro atomizing pump pressurizing and is supercritically atomized into about 0.5-1.5um fog drops in the high-frequency untrasonic vibration field. Then the smog droplets will be dispersed into aerosols by the inhaled airflow and finally the aerosol will be formed into vapour which simu
