Abstract

There is provided an aerosol-generating system (10) comprising a cartridge (14), an aerosol-generating device (12) and a piercing element (26). The cartridge (14) comprises a cartridge housing (36), and a solid aerosol-forming substrate (38) and a liquid storage housing (44) each positioned within the cartridge housing (36). The cartridge (14) also comprises a liquid aerosol-forming substrate (40)positioned within the liquid storage housing (44) and a frangible seal (48) provided on the liquid storage housing (44). The aerosol-generating device (12) comprises a device housing (16) defining acavity (18) for receiving the cartridge (14), an electric heater (28), a power supply (22) and a controller (24) for controlling a supply of electrical power from the power supply (22) to the electricheater (28). The piercing element (26) is configured to pierce the frangible seal (48) when the cavity (18) receives the cartridge (14). The electric heater (28) is positioned externally from the piercing element (26).

Description

technical field [0001] The present invention relates to an aerosol generating system comprising a cartridge having solid and liquid aerosol-forming substrates and an aerosol generating device having a piercing element. The invention is particularly suitable for use as an electrically operated smoking system. Background technique [0002] One type of aerosol generating system is an electrically operated smoking system. Known hand-held electrically operated smoking systems typically comprise an aerosol-generating device comprising batteries, control electronics and an electric heater for heating the aerosol-forming substrate. An aerosol-forming substrate may be contained within a portion of the aerosol-generating device. For example, an aerosol-generating device may comprise a liquid storage portion in which a liquid aerosol-forming substrate, such as a nicotine solution, is stored. Such devices are often referred to as "e-cigarettes" and they generally contain sufficient l...
