Embodiment Construction

[0109] Figures 1a to 1d is a schematic diagram of an aerosol generating system comprising a cartridge according to an embodiment of the invention. Figure 1a Is a schematic illustration of an aerosol generating device 10 and a separate cartridge 20 which together form an aerosol generating system. In this example, the aerosol generating system is an electrically operated smoking system.

[0110] Cartridge 20 contains an aerosol-forming substrate and is configured to be received within cavity 18 within the device. When the aerosol-forming substrate provided in the cartridge 20 is exhausted, the cartridge should be replaceable by the user. Figure 1a Cartridge 20 is shown just prior to insertion into the device, wherein Figure 1a Arrow 1 in indicates the direction of cartridge insertion.

[0111] The aerosol-generating device 10 may be portable and may be about the size of a conventional cigar or cigarette. The device 10 comprises a body 11 and a mouthpiece portion 12 . ...

Abstract

An aerosol-generating system comprising a liquid storage portion (20) comprising a rigid housing (24) holding a liquid aerosol-forming substrate, the housing having an opening and a fluid permeable heater assembly (30) comprising a plurality of electrically conductive filaments, wherein the fluid permeable heater assembly is fixed to the housing and extends across the opening of the housing. The provision of a heater assembly that extends across an opening of a liquid storage portion allows for a robust construction that is relatively simple to manufacture. This arrangement allows for a large contact area between the heater assembly and liquid aerosol-forming substrate. The heater assembly may be substantially flat allowing for simple manufacture.

Description

technical field [0001] The present invention relates to an aerosol generating system comprising a heater assembly adapted to vaporize a liquid. In particular, the present invention relates to handheld aerosol generating systems, such as electrically operated smoking systems. Background technique [0002] One type of aerosol generating system is an electrically operated smoking system. Hand-held electrically operated smoking systems consisting of a device part comprising batteries and control electronics and a cartridge part comprising an aerosol-forming substrate supply and an electrically operated vaporizer are known. Cartridges that include both an aerosol-forming substrate supply and a vaporizer are sometimes referred to as "atomizing cartridges". Vaporizers generally comprise a coil of heater wire wrapped around an elongated wick immersed in a liquid aerosol-forming substrate. The cartridge portion usually includes not only an aerosol-forming substrate supply and an e...
