Embodiment Construction

[0092] figure 1 There is shown an aerosol generating system 10 comprising an aerosol generating device 12 and an aerosol forming cartridge 14 according to one embodiment of the invention.

[0093] The aerosol-generating device 12 includes a body 16 defining a cavity including an opening at a downstream end of the body 16 through which the aerosol-forming cartridge 14 is inserted into the cavity. The device 12 also includes an electrical contact assembly 18 disposed adjacent the opening for receiving the aerosol-forming cartridge.

[0094] A removable mouthpiece 20 is provided at the upstream end of the device 12, wherein the mouthpiece 20 is removed from the device 12 so that the aerosol-forming cartridge 14 can be inserted into the device 12, and then after the aerosol-forming cartridge 14 is fully inserted, the mouthpiece 20 is re-inserted. Attached to device 12. The mouthpiece cover 22 is removable to cover the mouthpiece 20 when the device 12 is not in use.

Abstract

The present invention relates to an electrically operated aerosol generating system (10) comprising an aerosol generating device (12), and first and second removable aerosol-forming cartridges (40, 60) each comprising a resistive heater. The first removable aerosol-forming cartridge (40) includes a first aerosol-forming substrate requiring a first heating profile, and the second removable aerosol-forming cartridge (60) includes a second aerosol requiring a second heating profile form the matrix. The aerosol-generating device (12) includes a body (16) defining a cavity, and for removably receiving one of the first and second aerosol-forming cartridges (40, 60) in the cavity. The sol forms at least one opening of the cartridge. The aerosol generating device (12) also includes a power supply and a control unit for controlling the supply of current from the power supply to the resistance heater. The control unit is arranged to detect whether a first or second aerosol-forming cartridge (40, 60) has been received in said chamber based on the resistive load of the respective resistive heater. The control unit is further configured to control the supply of current to the at least one resistive heater according to the first heating profile or the second heating profile in response to detecting the aerosol-forming cartridge.

Description

technical field [0001] The present invention relates to an aerosol generating system configured to detect and identify different types of aerosol forming cartridges. The present invention finds particular application in the use of an aerosol generating system for heating a nicotine-containing aerosol-forming substrate. Background technique [0002] One type of aerosol generating system is an electrically operated smoking system. Hand-held electrically operated smoking systems are known which consist of an electric heater, an aerosol-generating device including batteries and control electronics, and an aerosol-forming cartridge. [0003] Aerosol-forming cartridges for electrically operated smoking systems are generally only designed specifically for the corresponding aerosol-generating device, since the flavor is generated and released by controlled heating of the aerosol-forming substrate. Therefore, when attempting to use, for example, an aerosol-generating device with an...
