摘要： An electrically operated aerosol-generating system may include a reservoir configured to hold a liquid aerosol-forming substrate, an atomizer assembly configured to vaporize the liquid aerosol-forming substrate to form an aerosol, and a pump configured to convey the liquid aerosol-forming substrate from the reservoir to the atomizer assembly. The reservoir may include a substantially rigid housing and an inlet valve that is configured to allow air into the reservoir based on a pressure difference between an interior of the housing and an exterior of the housing exceeding a threshold pressure difference. This improves the reliability and efficiency of delivery of liquid to the wick. The system may further include a robust reservoir that is configured to at least partially mitigate liquid leakage between the reservoir interior and the reservoir exterior.

摘要： A non-combustion-type flavor inhaler includes: an atomization assembly including an atomizer configured to atomize an aerosol source without combustion; and a power supply assembly including a power supply for supplying power to the atomizer. The power supply assembly includes: paired electrodes for electrical connection with the atomizer; and a first electrode and a second electrode electrically connected with the power supply. At least one of the first electrode and the second electrode is electrically connectable to a charger for charging the power supply. The non-combustion-type flavor inhaler is provided with a control circuit configured to detect a predetermined current in an opposite direction to a direction of a current flowing through the first electrode or the second electrode when the charger charges the power supply.

摘要： An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.
