TECHNICAL FIELDThis application relates to the field of e-cigarettes, and in particular, to an aerosol-generation system and a charging box.
BACKGROUNDMany vaporization devices (such as an e-cigarette or another electronic nicotine delivery system) are formed by two main components (a vaporizer and a power supply apparatus). A typical vaporizer generally has a function of accommodating a liquid substrate, which includes a reservoir for accommodating a liquid and a vaporization element for evaporating the liquid. The vaporization element is generally implemented as a resistive heater such as a heating wire coil. The power supply apparatus generally includes a battery for supplying power to the vaporization element and a control portion for controlling output power of the battery. In existing products, the power supply apparatus generally further includes an airflow sensor. During operation, the power supply apparatus may activate the vaporizer to work by detecting when a user performs inhalation on an inhaler through an airflow sensor, for example, to control the battery to supply power to the vaporization element. This activation causes the vaporization element to evaporate a small amount of liquid from the reservoir, and an aerosol is generated and then inhaled by the user together with an airflow.
A typical vaporization device is not portable due to size limitations, so it is often used together with a charging box. The charging box provides charging and endurance for the vaporization device. The known problem is that when the vaporization device is placed in the charging box, a gas in a cavity is often compressed to trigger a sensor of the vaporization device, causing false start-up of the vaporization device.
