The resistance test of e-cigarette is mainly used to measure the resistance of e-cigarette, which is suitable for quality control of e-cigarette production and testing of e-cigarette. When the device simulates the smoking action of people and inhales the air with a fixed flow rate of 17.5ml/s on the e-cigarette, a certain vacuum pressure will be generated at the suction end of the e-cigarette, and this pressure is the suction resistance, referred to as the suction resistance. The suction resistance can be measured by measuring this pressure.
