Abstract

A smoking article includes identification information encoded on the smoking article. The smoking article can be used with an electrically heated smoking system having a detector for detecting the smoking article and distinguishing the smoking article from other articles based on the identification information. A cleaning article includes identification information encoded on the cleaning article. The cleaning article cleans an electrically heated smoking system having a detector for detecting the cleaning article and distinguishing the cleaning article from other articles based on the identification information. An electrically heated smoking system for receiving an article configured for use with the smoking system includes: a cavity for receiving the article having identification information encoded thereon, a heating element, a power supply, electrical hardware, and a detector capable of detecting the presence of the article in the cavity and distinguishing the article from other articles based on the identification information.

First claim

We claim:

1. A cleaning article comprising:
encoded identification information on the cleaning article, said cleaning article being configured for cleaning an electrically heated smoking system having a detector for detecting the cleaning article and distinguishing the cleaning article from other articles based on the encoded identification information.

2. The cleaning article of claim 1 , wherein the identification information is printed on the article.

3. The cleaning article of claim 1 , wherein the identification information comprises at least one of visible ink, ultra violet (UV) ink, infra red (IR) ink, phosphorescent ink, fluorescent ink or metallic ink.

4. The cleaning article of claim 1 , wherein the identification information comprises one or more of: smoking article type, aerosol-forming substrate type, cleaning article type, cleaning means information, cleaning ingredient type, date of production, place of production, production batch number, other production details, and use-by date.

5. The cleaning article of claim 1 , wherein the identification information is arranged to change as the article is used.

6. An electrically heated smoking system for receiving the cleaning article of claim 1 , the system comprising:
a cavity for at least partially receiving the cleaning article, the cleaning article including the encoded identification information thereon;
at least one heating element;
a power supply for supplying power to the at least one heating element;
electrical hardware connected to the power supply and the at least one heating element; and
a detector capable of detecting the presence of the cleaning article in the cavity and distinguishing the cleaning article from a smoking article receivable in the cavity among articles, based on the identification information.

7. The electrically heated smoking system of claim 6 , wherein the system is arranged to initiate, when the detector detects the cleaning article in the cavity.

8. The electrically heated smoking system of claim 6 , wherein the electrical hardware is arranged to establish a heating protocol for the at least one heating element based on the cleaning article identified by the detector.

9. The electrically heated smoking system of claim 6 , wherein the detector comprises an optical sensor including at least one light emitter and at least one light sensor, and the identification information is printed on the cleaning article.

10. The electrically heated smoking system of claim 6 , wherein the identification information is configured to be altered during heating so as to indicate whether the cleaning article has been used.
