The present invention concerns an aerosol generation device comprising a finishing element.
The present invention also concerns an assembly method of such an aerosol generation device.
BACKGROUND OF THE INVENTIONDifferent types of aerosol generation devices are already known in the art. Generally, such devices comprise a storage portion for storing an aerosol forming precursor, 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 precursor 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.
In some aerosol generation devices, the precursor is stored in a removable cartridge. Thus, when the precursor 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.
The operation of an aerosol generation device is carried out at least partially by its internal components comprising notably a battery, a printed circuit board and at least a part of the heating system connected to the battery through the circuit board. The internal components may be mounted on a bracket, also called chassis, which is inserted into an outside casing. The outside casing ensures the external design of the device and is handled by the user while operating the aerosol generation device. It protects the internal components of the device against external influence as well as the user against eventual internal problems as for example overheating or battery problems.
One can conceive that it is important to fix the bracket with mounted internal components inside the outside casing. According to the art, it can be done using pins positioned on opposite sides of the outside casing and traversing it to retain the bracket. It can also be done using for example screws or other fixing elements. However, such fixing elements may have a strong visual impact on the external design of the device.

Before describing the invention, it is to be understood that it is not limited to the details of construction set forth in the following description. It will be apparent to those skilled in the art having the benefit of the present disclosure that the invention is capable of other embodiments and of being practiced or being carried out in various ways.
As used herein, the term “aerosol generation device” or “device” may include a vaping device to deliver an aerosol to a user, including an aerosol for vaping, by means of aerosol generating unit (e.g. an aerosol generating element which generates vapor which condenses into an aerosol before delivery to an outlet of the device at, for example, a mouthpiece, for inhalation by a user). The device may be portable. “Portable” may refer to the device being for use when held by a user. The device may be adapted to generate a variable amount of aerosol, e.g. by activating a heater system for a variable amount of time (as opposed to a metered dose of aerosol), which can be controlled by a trigger. The trigger may be user activated, such as a vaping button and/or inhalation sensor. The inhalation sensor may be sensitive to the strength of inhalation as well as the duration of inhalation to enable a variable amount of vapor to be provided (so as to mimic the effect of smoking a conventional combustible smoking article such as a cigarette, cigar or pipe, etc.). The device may include a temperature regulation control to drive the temperature of the heater and/or the heated aerosol generating substance (aerosol pre-cursor) to a specified target temperature and thereafter to maintain the temperature at the target temperature that enables efficient generation of aerosol.
As used herein, the term “aerosol” may include a suspension of precursor as one or more of: solid particles; liquid droplets; gas. Said suspension may be in a gas including air. Aerosol herein may generally refer to/include a vapor. Aerosol may include one or more components of the precursor.
As used herein, the term “aerosol-forming precursor” or “precursor” or “aerosol-forming substance” or “substance” or “vaporizable material” is used to designate any material that is vaporizable in air to form aerosol. Vaporisation is generally obtained by a temperature increase up to the boiling point of the vaporization material, such as at a temperature up to 400° C., preferably up to 350° C. The vaporizable material may, for example, comprise or consist of an aerosol-generating liquid, gel, or wax or the like or an aerosol—generating solid that may be in the form of a rod, which contains processed tobacco material, a crimped sheet or oriented strips of reconstituted tobacco (RTB), or any combination of these. The vaporizable material may comprise one or more of: nicotine; caffeine or other active components. The active component may be carried with a carrier, which may be a liquid. The carrier may include propylene glycol or glycerin. A flavoring may also be present. The flavoring may include Ethylvanillin (vanilla), menthol, Isoamyl acetate (banana oil) or similar.
