Description

FIELD OF THE INVENTION The present invention concerns an aerosol generation set comprising a pair of magnetic elements. The aerosol generation set according to the invention further comprises an aerosol generation device and a case configured to receive such a device. The present invention also concerns an operation method associated to such an aerosol generation set. BACKGROUND OF THE INVENTION Different types of aerosol generation devices are already known in the art. Generally, such devices comprise a storage portion for storing a vaporizable material, which can comprise for example a liquid or a solid. A heating system is formed of one or more electrically activated resistive heating elements arranged to heat said vaporizable material to generate the aerosol. The aerosol is released into a flow path extending between an inlet and outlet of the device. The outlet may be arranged as a mouthpiece, through which a user inhales for delivery of the aerosol. For example, such an aerosol generation device is known from GB 2 542 010 A. In some aerosol generation devices, the vaporizable material is stored in a removable cartridge. Thus, when the vaporizable material is consumed, the cartridge can be easily removed and replaced. In order to attach the removable cartridge to the device body, a screw-threaded connection can for example be used. Some aerosol generation devices are configured to be stored in a case. Such a case may be adapted to receive an aerosol generation device, eventually with a removable cartridge. This can simplify carrying of the device and protect it for example against shocks. Some cases can also prevent leakage of the vaporizable material contained in the cartridge. According to some examples, the case can be provided with a rechargeable battery able to recharge the battery of the aerosol generation device when for example an external power source is not available. According to some other examples, the case can allow the device power connection to an external power source and/or device data connection with an external device. A case can thus present an important object for the user of an aerosol generation and its UX design ("user experience design") has to be constantly improved. Particularly, easy operation of the case until using the aerosol generation device is essential for most of the users. For example, some users may expect to be able to operate the case and the aerosol generation device using one hand. SUMMARY OF THE INVENTION One of the aims of the present invention is to improve the UX design of an aerosol generation set and make it easier to be operated by a user. For this purpose, the invention relates to an aerosol generation set according to independent claim 1.

Thanks to these features, the case including the aerosol generation device can be easily operated. For example, the aerosol generation device can be easily removed from the case when the user is intending to use the device. Additionally, this extraction can be performed using only one hand. According to some embodiments, the case is closed when the movable part is in the closed position and the case is opened and the aerosol generation device is able to be put into the cavity or removed from it when the movable part is in the opened position. According to some embodiments, the movable part forms an access lid to the case. Thanks to these features, the aerosol generation device can be easily removed from the case after being carried inside the case in a closed position. According to some embodiments, the trigger event consists in a manual opening of the case or in activating a button by a user Thanks to these features, the aerosol generation device can be removed from the case upon its opening. According to some embodiments, the case is a charging case configured to charge the aerosol generation device when it is received in the cavity. Thanks to these features, the aerosol generation device can be charged while being stored in the case. One of the said magnetic elements is a permanent magnet and the other is a coil connected to the electric circuitry and configured to generate a magnetic field repelling the permanent magnet. Thanks to these features, a magnetic interaction between
