Problems solved by technology
The tobacco sheets closest to the heater blades may be heated differently than the tobacco sheets furthest from the heater, which may lead to variability in the amount of aerosol generated over time and possible overheating of the tobacco sheets closest to the heater

Embodiment Construction
[0085] figure 1 A cross-sectional view of an aerosol generating system or an aerosol generating system or device is shown. The aerosol forming article includes substantially spherical or spherical beads or pellets 1, the beads or pellets having core 2 coated with an aerosol forming substrate 4. The core 2 is made of glass, and the glass is an inert material, so it does not produce unwanted by-products when the bead 1 is heated. The glass also has a high melting temperature, so that it is possible to withstand the temperature (usually less than 500 ° C) during the heating period (usually less than 500 ° C) without losing its structural integrity. The glass core 2 is also smooth and non-permeable or non-porous, so that the aerosol forming substrate 4 is only located on its surface. This makes it easier to accurately control the amount of aerosol forming the matrix 4 on the surface of the core 2, and reduce the variability between the beads.

Abstract
An aerosol-generating system comprises an aerosol-generating article (1), and the aerosol- generating article comprises a single metered dose of an aerosol-forming substrate; an airflow pathway (108) arranged between an air inlet (110) and an air outlet (112); an aerosolisation chamber (116) arranged at a location along the airflow pathway (108) such that the airflow pathway passes through at least a portion of the aerosolisation chamber (116); and a flow controller (122, 124) for selectively controlling the flow of air through the airflow pathway (108). The flow controller (122, 124) has an open configuration in which air can flow into and out of the aerosolisation chamber (116) and a closed configuration in which air is substantially prevented from flowing into and out of the aerosolisation chamber (116), wherein the aerosolisation chamber (116) is configured to open to receive only one aerosol-generating article (1) at a time; and the aerosolisation chamber (116) is configured to close to contain the aerosol-generating article (1). The aerosol-generating system further comprises a heating element (118, 120) arranged to heat the aerosolisation chamber (116) when the aerosol- generating article (1) is received within the aerosolisation chamber (116), wherein the aerosol-generating system is configured to heat the aerosolisation chamber (116) containing the aerosol-generating article (1) only when the flow controller (122, 124) is in the closed configuration.
Description
Technical field [0001] The present invention relates to an aerosol generating system for use with a device for use with the system, and a method of producing an aerosol. In particular, the present invention relates to a hand-held gas sol generating system and apparatus, which forms a matrix by heating to form a matrix to produce an aerosol to suck or inhale from the user. Background technique [0002] Hand-held electric operating aerosol generating means and system is known from the apparatus portion including a battery and control electronics, a portion for receiving or receiving an aerosol forming a matrix and an electric operation heating for heating an aerosol to generate an aerosol. Composition. It also includes a tobacco portion, and the user can suck it on the tobacco portion to inhale an aerosol into their mouth. [0003] Some devices and systems form a matrix or electron liquid in a liquid aerosol stored in a liquid storage portion. Such devices typically use the core to...
