Abstract: A refilling device for an article of an aerosol provision system includes refilling control circuitry. The refilling control circuitry is configured to facilitate the transfer of aerosol-generating material from a reservoir to the article when the article is coupled to the refilling device. The refilling control circuitry causes a value of a counter stored on the reservoir to be updated in response to the transfer of the aerosol-generating material. The value of the counter is indicative of the amount of an aerosol generating material in the reservoir.

Abstract: A refilling device for an article of an aerosol provision system includes an article interface configured to receive the article and refilling control circuitry. The refilling circuitry is configured to read, from the article in response to the article being received by the article interface, an indication of a number of times the article has been refilled with aerosol generating material, and transmit, to a remote data store using a wireless communications protocol, the indication.

Abstract: A computer is configured to receive, from a refilling device for an article of an aerosol provision system associated with the computer via a remote data store using a wireless communications protocol, an indication of a number of times the article of the aerosol provision system has been refilled with aerosol generating material. The computer is then configured to provide the indication to a user of the computer.

Abstract: A refilling device for an article of an aerosol provision system includes refilling control circuitry. The refilling control circuitry is configured to facilitate the transfer of aerosol-generating material from a reservoir coupled to the refilling device to the article and cause a value of a counter to be updated in response to the transfer of the aerosol-generating material. The value of the counter is indicative of a number of times the article has been refilled. The refilling control circuitry determines if the article is expired based on a comparison between the updated value of the counter and a refill limit and writes data to computer-readable memory indicating that the article is expired in response to determining that the article is expired.

Abstract: A refilling device for an article of an aerosol provision system includes comprises refilling control circuitry. The refilling control circuitry is configured to read data from the article in response to the article being received by the refilling device and prevent a transfer of aerosol generating material from a reservoir coupled to the refilling device to the article in response to determining that the data indicates that the article has expired.

Abstract: The present disclosure relates to a housing for an aerosol provision system. The housing comprising a reservoir for an electrically conductive aerosolisable material, wherein the potential difference between any two exposed and/or exposable surfaces of one or more metal components which are contained in the housing, is from 0 mV to about 35 mV, wherein the two surfaces are capable of simultaneously being in contact with the aerosolisable material. Also disclosed is a cartomiser comprising a reservoir containing an electrically conductive aerosolisable material, and two exposed and/or exposable surfaces of one or more metal components, wherein the two surfaces are capable of simultaneously being in contact with the electrically conductive aerosolisable material and wherein the change in dissolved metal content of the electrically conductive aerosolisable material after storage of the cartomiser for about 1 to about 8 weeks at about 40° C. is between 0 and about 20%.

Abstract: A vapor provision system includes an aerosol delivery section configured to generate aerosol from liquid in a reservoir, an airflow path through the aerosol delivery section extending from an air inlet to a mouthpiece, a battery section configured to join to the aerosol delivery section and house a battery to provide electrical power to one or more components in the aerosol delivery section, the battery section arranged laterally to at least a portion to the aerosol delivery section with respect to a direction of airflow through the mouthpiece, and an interface region in which a surface of the aerosol delivery section faces a surface of the battery section when the sections are joined, the air inlet being located on the aerosol delivery section in the interface region so as to take in air that has been channeled over part of the battery section.

Abstract: An aerosol delivery component for a vapor provision system includes an air inlet, an airflow path connected to the air inlet and extending through the aerosol delivery component, and an airflow adjuster for varying a level of airflow along the airflow path, the airflow adjuster located in the airflow path downstream from the air inlet.
