Aerosol generating system with means for disabling consumable
An aerosol generating system is provided, including: a storage portion for storing an aerosol-forming substrate, an aerosol generating element for generating an aerosol from the aerosol-forming substrate, control circuitry in communication with the storage portion, and disabling component within the storage portion for rendering the storage portion inoperable in the aerosol generating system in response to a disable signal from the control circuitry. There is also provided a method in an aerosol generating system, including sending a disable signal from the control circuitry to the disabling component following a determination that an amount of the aerosol-substrate in the storage portion is below a threshold level or following a determination of a malfunction in the system.
1. An aerosol generating system, comprising:
a storage portion for storing an aerosol-forming substrate;
an electric heater configured to heat the aerosol-forming substrate to generate an aerosol;
a control circuitry in communication with the storage portion or the electric heater; and
disabling means for rendering the storage portion inoperable in the aerosol generating system in response to a disable signal from the control circuitry,
wherein the control circuitry is configured to determine or estimate when an amount of aerosol-forming substrate in the storage portion is below a threshold amount based on a determination that a temperature or resistance of the electric heater is above a predetermined threshold, and to issue the disable signal when the amount of aerosol-forming substrate in the storage portion is determined or estimated to be below the threshold amount,
wherein the aerosol generating system is an electrically operated smoking system, and
wherein the disabling means is a component that is configured to be switched or damaged by the disable signal to render the storage portion inoperable in a permanent manner.
2. The aerosol generating system according to claim 1 , further comprising a main body, wherein the storage portion is a consumable cartridge configured to couple to the main body.
3. The aerosol generating system according to claim 2 , wherein the control circuitry is arranged in the main body of the aerosol generating system.
4. The aerosol generating system according to claim 1 , wherein the component is an electrical fuse.
5. The aerosol generating system according to claim 1 , wherein the control circuitry is configured to issue the disable signal when the control circuitry has detected a malfunction in the aerosol generating system.
