Abstract

A method for generating an aerosol from an aerosol generating material using an aerosol delivery device is disclosed. The method includes the step of supplying power to a heating element to begin heating the aerosol generating material to an operating temperature (e.g., a temperature at which the aerosol is generated). The method provides a signal to a user indicating that, after a first predetermined time, the user may begin inhaling from the device. The method reduces the supply of power to the heating element after a second predetermined time or after the user has stopped inhaling. In this way, the user may be guided to inhale from the device. The timing may be adjusted to suit a specific delivery and/or device.

Description

ELECTRONIC AEROSOL PROVISION SYSTEM The present disclosure relates to non-combustible aerosol provision systems. Electronic aerosol delivery systems, such as e-cigarettes, generally possess a reservoir of a source liquid containing a formulation typically containing nicotine, from which an aerosol is generated, for example, through heat vaporization. Thus, the aerosol source for the aerosol delivery system may include a heater having a heating element arranged to receive the source liquid from the reservoir, for example, through wicking/capillary action. While the user inhales from the device, power is supplied to the heating element to vaporize the source liquid near the heating element, thereby generating an aerosol for inhalation by the user. Such devices are typically provided with one or more air inlet holes located away from the mouthpiece end of the system. When the user sucks on the mouthpiece connected to the mouthpiece end of the system, air is drawn in through the inlet holes and past the aerosol source. A flow path exists connecting the mouthpiece opening and the aerosol source. Accordingly, air inhaled after passing the aerosol source follows the flow path to the mouthpiece opening, where a portion of the aerosol from the source is carried along with the air. The aerosol-carrying air exits the aerosol delivery system through the mouthpiece opening for inhalation by the user. Other aerosol delivery devices generate aerosols from solid materials such as tobacco or tobacco derivatives. Such devices operate in a manner largely similar to the aforementioned liquid-based systems in that the solid tobacco material is heated to an evaporation temperature to generate an aerosol, which is subsequently inhaled by the user. In heated systems, care must be taken to ensure that the heated material does not reach excessive temperatures to carbonize or burn, thereby preventing the generation of undesirable components delivered to the aerosol. Meanwhile, some heated systems require a significant amount of time to reach the operating temperature. Various approaches that help solve some of these problems are described. According to a first aspect of specific embodiments, a method for generating an aerosol from an aerosol generating material using an aerosol providing device is provided, the method comprising: supplying power to a heating element to begin heating the aerosol generating material to an operating temperature; providing a signal to a user indicating that the user may begin inhaling from the device after a first predetermined time; and reducing the supply of power to the heating element after a second predetermined time or after the user has stopped inhaling. In some embodiments, the operating temperature of the heating element is set based on the length of a first predetermined time period. In some embodiments, the operating temperature (T op ) of the heating element is set as follows: T op = A - (B xt delay ), Here, A and B are constants, and t delay is the first predetermined time. In some embodiments, when the first predetermined time is greater than 0 (zero) seconds and less than 8 seconds, the heating element is heated to an operating temperature of 200°C to 350°C. In some embodiments, when the first predetermined time is 2 to 8 seconds, the heating element is heated to an operating temperature of 200°C to 270°C. In some embodiments, when the first predetermined time is 2 to 8 seconds, the heating element is heated to an operating temperature of 220°C to 250°C. In some embodiments, when the first predetermined time is 0 to 2 seconds, the heating element is heated to an operating temperature of more than 250°C and/or more than 270°C. In some embodiments, the heating element is heated to an operating temperature of 350°C or lower. According to an embodiment, the method further comprises the step of supplying power to a heating element before supplying power to the heating element for a first predetermined period, and the power supplied before the first predetermined period is set to a level such that the heating element is heated to a temperature below the operating temperature. In some embodiments, the second predetermined time is 1 second to 10 seconds. In some embodiments, the aerosol-generating material is an amorphous solid.

In some embodiments, the thickness of the amorphous solid is 0.05 mm to 0.4 mm. In some embodiments, the signal can be perceived by the user by inhalation.
