    Abstract: An electronic vapor provision system includes a vaporizer for vaporizing liquid for inhalation by a user of the electronic vapor provision system; a power supply comprising a cell or battery for supplying power to the vaporizer; a sensor for measuring the rate of airflow through the electronic vapor provision system as a result of the inhalation by the user; and a control unit for controlling the power supplied to the vaporizer based on a cumulative airflow for this inhalation by the user, wherein the cumulative airflow is determined based on the measurements of airflow rate by the sensor. Such a system allows the user control over the amount of vaporized liquid obtained in a given inhalation based on the cumulative airflow for the given inhalation.

  • Patent number: 10455863
    Abstract: A cartridge for an e-vaping device enables separate vapors to be formed proximate to separate, respective ends of the cartridge. The cartridge includes multiple reservoirs and separate vaporizer assemblies coupled to separate reservoirs on opposite ends of the reservoirs. The separate reservoirs may hold separate pre-vapor formulations. The separate vaporizer assemblies may draw separate pre-vapor formulations from separate reservoirs towards opposite ends of the cartridge and vaporize the separate pre-vapor formulations via operation of separate heaters proximate to the separate ends. The separate heaters may be independently controlled to independently control vapor formation at the separate ends. The heaters may be controlled to independently control vapor formation rates proximate to the separate ends. The heaters may be controlled to form separate vapors at least one of simultaneously, concurrently, and at different times.

  • 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.

  • Patent number: 10433588
    Abstract: The present application discloses a personal vaporizer system with an e-liquid reservoir isolated from the atomizer. The isolation of the e-liquid reservoir from the atomizer eliminates particles contamination of the e-liquid held in the reservoir and chemical reactions between the atomizer and the e-liquid. Since the residence time of “fresh” e-liquid in the atomizer is only the necessary to vaporize a very small amount of e-liquid, particles contamination of the produced vapor and chemical reactions between the e-liquid and atomizer components are dramatically reduced. This represents a huge health benefit for the consumer, compared to all others personal vaporizers with an e-liquid reservoir. The disclosed system can be used in any type of personal vaporizer, for example in the electronic cigarette market.

  • Patent number: 10398177
    Abstract: The present invention relates to an electronic cigarette and a method for controlling the electronic cigarette. The method for controlling electronic cigarette comprises: reading the available smoking time when an atomization circuit of the electronic cigarette is in a turn-off state and the electronic cigarette detects a user's smoking action; determining whether or not the available smoking time is equal to or less than the first preset value to obtain a first determination result; when the first determination result is YES, outputting a prompt message to remind the user that e-liquid is almost to be exhausted, and outputting the available smoking time and/or available smoking times of the electronic cigarette; determining whether the available smoking time is greater than the second preset value to obtain a second determination result; controlling the atomization circuit to stay in the turn-off state when the second determination result is NO.
