Disposable electronic cigarettes are mainly composed of batteries, atomizers, and e-liquid. The working principle is that the battery provides energy to heat the heating wire in the atomizer to heat the e-liquid and atomize it into vapor, thereby generating smoke and taste similar to traditional cigarettes.
When the user inhales, the airflow sensor detects the change in airflow and triggers the battery to supply power to the atomizer. The heating wire in the atomizer rapidly heats up, heating the e-liquid to the evaporation temperature. The vapor formed after the evaporation of the e-liquid is inhaled into the user's lungs.
Disposable electronic cigarettes usually use an air switch or a microphone chip to control the output and working status of the smoke. The air switch is a device that controls the on and off of the circuit by sensing the airflow. When the user inhales, the air switch opens, connecting the circuit between the battery and the atomizer, thereby generating smoke. The microphone chip is a device that controls the on and off of the circuit by detecting sounds. When the user inhales, the microphone chip detects the sound of inhalation and triggers the battery to supply power to the atomizer, thereby generating smoke.
