  • Electronic cigarette with intelligent battery module
    Patent number: 10455862
    Abstract: An electronic cigarette includes a cigarette housing, a cartridge received in the cigarette housing, a vaporizer, and an intelligent battery module. The intelligent battery module includes a battery casing, a battery supporting tray for accommodating at least one battery, a Printed Circuit Board (PCB) supported in the battery casing and is electrically connected to the battery supporting tray, a Main Control Unit (MCU) implemented on the PCB, and a resistance detection circuitry implemented on the PCB for detecting a resistance of the heating element. When the resistance of the heating element reaches a predetermined upper threshold, the MCU is configured to lower or cut off a voltage supplied to the heating element. When the resistance of the heating element reaches a predetermined lower threshold, the MCU is configured to supply a normal voltage to the heating element of the vaporizer.
