Description

The present invention relates to an aerosol generating device or a case with a plurality of power sources. Each of the plurality of power sources can be designed with the possibility of removal and/or with the possibility of selection.

In some systems, the aerosol generating device is configured to accommodate an aerosol generating article comprising a solid aerosol forming substrate, such as an assembled corrugated tobacco sheet. In these systems, the device typically comprises an atomizer configured to heat the aerosol forming substrate when the article is placed in the device. The aerosol generating article may also comprise a filter that is wrapped together with the aerosol forming substrate in the form of a rod, similar to a traditional cigarette. In other systems, the device is configured to accommodate a cartridge comprising an atomizer and a liquid aerosol forming substrate. Such cartridges are often referred to as cartomizers. Common types of atomizer used in cartomizers comprise a coil of heater wire wound around an elongated wick impregnated with a liquid aerosol forming substrate.

Heating the aerosol-forming substrate can be an energy-intensive process. Large energy storage units may be required, which increases the size and weight of the aerosol-generating devices and may negatively impact the handling of such devices.

Some systems use an aerosol generating device with a single-use energy reserve in combination with a charging station or case with a higher energy storage capacity. The aerosol generating device can be removed from the charging station or case before use and reinserted into the charging station after use. The charging station or case can recharge the aerosol generating device between uses. Other systems include a charging station or case with an additional aerosol generating device. However, adding a second aerosol generating device can also double the need for cleaning such devices.

It would be desirable to provide a solution to ensure continuous use of the aerosol generating device.

According to one aspect of the present invention, a charging case for an aerosol-generating device is proposed, wherein the charging case comprises a case connector, a plurality of case cavities, a mounting section and a case control unit. The case connector is configured to receive power from an external source. Each of the plurality of case cavities is configured to accommodate at least one of the plurality of power sources. The mounting section is configured to connect the aerosol-generating device to the charging case. The case control unit is configured to charge the first of the plurality of power sources via the case connector using power from the external power source and to charge the aerosol-generating device connected to the mounting section via the second of the plurality of power sources or via the case connector using power from the external power source.

Inclusion of a plurality of cavities of the case, configured to accommodate at least one of the plurality of power sources, can provide a redundancy of power sources and guarantee continued operation in the event of failure of one of the plurality of power sources, which is an advantage. Additionally, inclusion of a control unit of the case, configured to charge the aerosol-generating device through one of the plurality of power sources or through a connector of the case, can reduce the load exerted on the plurality of power sources, and thus increase their service life. For example, it is possible that the plurality of power sources are not charged and discharged simultaneously, and the charging case can charge the aerosol-generating device directly from an external power source. In addition, the mounting section can supply power to the aerosol-generating device and charge it during use of the device.

According to another aspect of the present invention, an aerosol generating device is proposed, comprising a heater for heating an aerosol-forming substrate; a device casing comprising a plurality of cavities for power sources, wherein each of the plurality of cavities for power sources is configured to accommodate at least one of the plurality of power sources; and a selector configured to select a first power source from said plurality of power sources inserted into the plurality of cavities for power sources, and configured to supply power to the heater from the selected first power source.
