Definitions
- the present invention relates to a vaping device, also called hereafter "aerosol generation device", and more precisely to a vaping device arranged for providing at least two different aerosols.
- Most of the aerosol generation devices comprise a first aerosol generation assembly comprising a first aerosol outlet (possibly defined in a mouthpiece (possibly exchangeable)) and configured for producing (by heating) a first aerosol that is delivered by this first aerosol outlet when their user inhales through this first aerosol outlet during a vaping session.
- a first aerosol generation assembly comprising a first aerosol outlet (possibly defined in a mouthpiece (possibly exchangeable)) and configured for producing (by heating) a first aerosol that is delivered by this first aerosol outlet when their user inhales through this first aerosol outlet during a vaping session.
- the user When vaping, the user inhales the aerosol specially designed to provide a pleasant sensory experience which essentially activates his taste receptors.
- the aerosol can be flavored to enhance the taste.
- odors and smells are also produced providing stimuli possibly interfering or complementing with the taste stimuli.
- the consumer experience might not be optimal, as for instance the olfactive experience might not be as pleasant or intense as expected and/or simply might not perfectly match the taste experience.
- an aerosol generation device further comprising a second aerosol generation assembly, configured for diffusing a second aerosol (and more precisely a scent (or flavor)) in surroundings of the aerosol generation device.
- This aerosol generation device comprises a mouthpiece with the first outlet for delivering the first aerosol into the mouth of its user and a scent reservoir that communicates with the surroundings through a membrane. This membrane releases passively and continuously the scent into the surroundings (or environment), which allows a continuous olfactory perception of this scent by the user and then an improvement of his sensory experience.
- the continuous and uncontrolled release of the scent into the surroundings might not be appropriate especially when this is not the right time, such as for instance when a vaping session is not taking place or when it is not allowed or else when it is disturbing for others.
- the intensity of the scent at a chosen instant cannot be controlled and the scent (or flavor) cannot be easily and rapidly changed.
- an object of this invention is to propose a solution to this problem, in particular to improve and better control the vaping sensory experience.
- This aerosol generation device is characterized in that its second aerosol generation assembly is configured for controllably diffusing at least one second aerosol that is a scent through at least one second aerosol outlet positioned on the aerosol generation device.
- the first aerosol generation assembly comprises a first aerosol outlet configured for releasing the first or heated aerosol.
- This first aerosol outlet may be formed in a permanent or exchangeable mouthpiece of the aerosol generation device.
- the embodiment of aerosol generation device may comprise other aspects or features, considered separately or combined, as defined hereafter.
- the invention aims at proposing an aerosol generation device 1 configured for controllably providing at least two different aerosols; one of which is released into the surroundings, to improve the overall sensory experience including the olfactive sensory experience.
- the aerosol generation device 1 is an E-vapor device. So, it comprises a first aerosol-forming substance 12 that is a liquid. But an aerosol generation device 1 according to the invention could be of another type, and notably it could be a T-vapor (or heat-not-burn) device, for instance, in which the aerosol-forming substance may be formed at least in part of tobacco and/or reconstituted tobacco substrate.
- the first aerosol-forming substance 12 may comprise one or more of nicotinoid(s), cannabinoid(s), caffeine, tobacco material, organic acids, salts, flavoring, and combinations thereof, and a carrier (e.g. a liquid solvent) which may include propylene glycol, glycerin, triethyl citrate (or TEC), triacetin, trimethylene glycol, water, ethanol, and combinations thereof.
- a carrier e.g. a liquid solvent
- TEC triethyl citrate
- anosol may include a suspension of substance as one or more of solid particles, liquid droplets and gas. Such a suspension may be in a gas including air.
- an aerosol generation device comprises at least first 2 and second 3 aerosol generation assemblies.
- the first aerosol generation assembly 2 is configured for producing a first aerosol by heating a first aerosol-forming substance 12 during a vaping session.
- the first aerosol generation assembly 2 may comprise a first aerosol outlet 4 and is configured for producing the first aerosol that is intended for being delivered by this first aerosol outlet 4 when a user inhales through this first aerosol outlet 4 during a vaping session.
- This first aerosol is generated from the first aerosol-forming substance 12 mixed with air.
- the first aerosol generation assembly 2 may comprise a cartridge (or capsule or else container (or reservoir)) 5 containing the first aerosol-forming substance 12 (here a liquid).
- a cartridge 5 may be exchangeable, in order to be manually replaced or refilled by the user when there is no more first aerosol-forming substance 12 in it.
- This exchangeable cartridge (or capsule) 5 can be installed manually, at least partly, into a dedicated cavity of the first aerosol generation assembly 2 or of an external casing (or body) 15 of the aerosol generation device 1 (which contains the first aerosol generation assembly 2).
- the first aerosol generation assembly 2 may comprise an aerosol generation unit 6, comprising a reservoir 5 containing the first aerosol-forming substance 12, an air flow channel 7, a heating chamber 32, a first heater 13, and a first aerosol channel 8.
- the aerosol generation unit 6 may be an exchangeable cartridge, capsule or pod. In a variant, only the reservoir 5 may be an exchangeable cartridge, capsule or pod.
- the first heater 13 is arranged for aerosolizing the first aerosol-forming substance 12 in the heating chamber 32 that is also fed with air provided by the air flow channel 7 and originating from outside, in order to generate a first aerosol.
- the heating chamber 32 may comprise a transport element 33 to transport the first aerosol-forming liquid 12 from the cartridge 5 to the heating chamber 32 in the area comprising the first heater 13.
- this transport element 33 may be a capillary element (possibly a capillary wick or mesh) having one end or two opposite ends.
- the first heater 13 may comprise a resistive coil wound around the capillary element 33 and connected to internal electrodes via lead wires. This first heater 13 is supplied with electrical energy originating from a first power source 14.
- the transport element can be made of ceramic, mesh or fibres of filaments.
- the first heater 13 may not necessarily be a resistive coil but may be an ohmic heater, such as an ohmic heating track printed on a surface of the transport element or a coil-and-wick assembly, or a thin film, or a micro-electronic-mechanical-system (or MEMS) having at least one microfluidic die and a heater arranged for heating liquid to force liquid through the die, or else may be an induction heater, for instance.
- an ohmic heater such as an ohmic heating track printed on a surface of the transport element or a coil-and-wick assembly, or a thin film
- MEMS micro-electronic-mechanical-system
- the first aerosol channel 8 is in fluid communication with the heating chamber 32 to collect the vaporized substance mixed with the air that defines the first aerosol.
- This first aerosol channel 8 comprises an outlet 10 for delivering the first aerosol to the user when the user is inhaling.
- the outlet 10 feeds a mouthpiece 11 comprising the first aerosol outlet 4.
- the outlet 10 of the first aerosol channel 8 could be the first aerosol outlet 4.
- the user temporarily couples the mouthpiece 11 to his mouth for inhaling the first aerosol during each puff (or draw or inhalation phase).
- the mouthpiece 11 may be integral with the external casing (or body) 15 of the aerosol generation device 1. But this mouthpiece 11 could be an additional part coupled to the external casing (or body) 15.
- the cartridge (or capsule or else container (or reservoir)) 5 could be part of a cartomizer, possibly exchangeable and further comprising the first heater 13.
- the cartridge can be a tobacco refill inserted into a device comprising the first heater 13, as illustrated in figure 7 (described below).
- the first power source 14 is housed in the external casing 15 of the aerosol generation device 1.
- the first power source 14 may be a rechargeable battery.
- the external casing 15 may comprise an electrical connector to which a charger cable may be connected during a charging session of the first rechargeable battery 14.
- a charger cable may be coupled to an (AC) adapter or to a wall socket.
- the charger cable and/or the (AC) adapter may belong to the aerosol generation device 1.
- the electrical energy supplied to the first heater 13 during a vaping session is controlled by a first controller 16.
- This first controller (or control unit) 16 may comprise at least a processor and a memory arranged for performing operations for controlling at least the first aerosol generation assembly 2 (and notably the first heater 13) during a vaping session and also the first power source 14 during a possible charging session.
- the processor may be a digital signal processor (or DSP), or an application specific integrated circuit (ASIC), or else a field programmable gate array (FPGA). More generally, the processor may comprise integrated (or printed) circuits, or several integrated (or printed) circuits connected therebetween through wired or wireless connections.
- integrated (or printed) circuits refers here to any type of device capable of carrying out at least one electric or electronic operation.
- the memory may be a random access memory (or RAM). But it may be any type of device arranged for storing program instructions for the processor.
- the functions of the first controller (or control unit) 16 may be carried out through the operation of program logic, through dedicated logic, through the interaction of program control and dedicated logic, or even manually (by the user). These functions may be provided through the use of dedicated hardware as well as hardware capable of executing software in association with appropriate software.
- the first controller (or control unit) 16 (and notably its processor and memory) may be fixed onto a first printed circuit board (or PCB) 17 (here housed in the external casing 15).
- PCB printed circuit board
- the first controller (or control unit) 16 may also comprise, in addition to its processor and memory, an input interface, a mass memory (notably for storing intermediate data produced during its calculus and processing), and an output interface for delivering messages and instructions at least for controlling the aerosol generation assembly 2 (and notably the first heater 13) and the electronic component(s) (such as switch(es)) supplying the electrical power (stored in the first power source 14) to the first aerosol generation assembly 2.
- a mass memory notably for storing intermediate data produced during its calculus and processing
- an output interface for delivering messages and instructions at least for controlling the aerosol generation assembly 2 (and notably the first heater 13) and the electronic component(s) (such as switch(es)) supplying the electrical power (stored in the first power source 14) to the first aerosol generation assembly 2.
- the second aerosol generation assembly 3 is configured for controllably diffusing at least one second aerosol that is a scent into the surroundings of the aerosol generation device 1, through at least one second aerosol outlet 18 that is positioned on the aerosol generation device 1.
- the second aerosol outlet 18 is preferably positioned on a lateral side of the aerosol generation device (as illustrated non limitatively), or on an end opposite to the first aerosol outlet 4, such as on the bottom end of the aerosol generation device 1.
- Each second aerosol outlet 18 may be defined in the external casing 15 of the aerosol generation device 1 as illustrated in the non-limiting examples of figures 1 and 3 to 6 , or in an external casing (or body) 22 of the second aerosol generation assembly 3 as illustrated in the non-limiting example of figure 2 .
- the control of the diffusion of the scent (or second aerosol) into the surroundings of the aerosol generation device 1 it is now possible to improve the sensory experience by properly controlling the olfactive release, e.g. to prevent releasing (or diffusing) scent in the user's environment (for instance to not disturb neighbor(s)), or else to decrease or increase the intensity of the scent at any time before, during or after a vaping session. Therefore, the sensory experience of the user and/or of the user's neighbors can be improved.
- the second aerosol generation assembly 3 may be configured to automatically activate for diffusing the second aerosol after a chosen or predetermined number of successive user's suctions (or puffs). This allows to reproduce automatically the beginning of a cigarette smoking session, because the releasing (or diffusion) of scent only starts after the chosen or predetermined number of user's suctions (or puffs).
- This number may be chosen by the user by means of a user interface of the first aerosol generation assembly 2 or of the second aerosol generation assembly 3, or may be fixed (by design) and therefore not modifiable by the user.
- the automatic activation can be triggered by the first controller 16 (when the second aerosol generation assembly 3 does not comprise its own second controller 19 as illustrated in the non-limiting examples of figures 3 to 6 ), or by a second controller 19 of the second aerosol generation assembly 3 (as illustrated in the non-limiting examples of figures 1 and 2 ).
- the second controller 19 needs to be coupled to the first controller 16 to be informed when the chosen or predetermined number of user's suctions (or puffs) has been reached.
- the chosen or predetermined number may be comprised between three and eight.
- the chosen or predetermined number may be equal to four or five.
- the chosen or predetermined number may take any value as it depends notably on the flavor intensity and/or the efficiency to diffuse and/or on the user's preference, but also on the number of puffs per vaping session. For instance, if one considers an average of twelve puffs per vaping session, the scent may be diffused before reaching the middle of the vaping session.
- the second aerosol generation assembly 3 may be configured to automatically activate for diffusing the second aerosol at the same time as the first aerosol generation assembly 2 or after the first aerosol generation assembly 2 has been activated for diffusing the first aerosol. This does not mean it is necessary that the release (or diffusion) of scent starts when the second aerosol generation assembly 3 has been activated. Indeed, the release (or diffusion) of scent may be delayed by scheduling after the activation of the second aerosol generation assembly 3.
- the automatic activation can be triggered by the first controller 16 (when the second aerosol generation assembly 3 does not comprise its own second controller 19 as illustrated in the non-limiting examples of figures 3 to 6 ), or by a second controller 19 of the second aerosol generation assembly 3 (as illustrated in the non-limiting examples of figures 1 and 2 ).
- the second controller 19 needs to be coupled to the first controller 16 to be informed when the first aerosol generation assembly 2 is or has been activated.
- the second aerosol generation assembly 3 may be configured for being manually activated by the user. So, in this case it is the user who decides when he wants the scent to be released (or diffused) by activating the second aerosol generation assembly 3.
- Such an activation can be controlled by means of a dedicated button 20 that is fixed to the external casing 15 of the aerosol generation device 1 as illustrated in the non-limiting examples of figures 1 and 3 , or in an external casing (or body) 21 of the second aerosol generation assembly 3 as illustrated in the non-limiting example of figure 2 .
- this activation can be controlled by selecting a dedicated sub menu by means of a user interface of the first aerosol generation assembly 2 (under control of its first controller 16) or of the second aerosol generation assembly 3 (under control of its second controller 19).
- the second aerosol generation assembly 3 may be activated by a mechanical pusher using hand pressure to squeeze the container or a deformable chamber containing a second aerosol-forming substance 21, from which the second aerosol (or scent) is generated, and expel this second aerosol-forming substance 21 through a delivery nozzle such as a spray nozzle.
- the external casing 15 of the aerosol generation device 1 may house removably at least a part of the second aerosol generation assembly 3. This allows replacing the whole second aerosol generation assembly 3 or a part of the latter (3), and notably the element containing the second aerosol-forming substance 21, or else refilling this element with second aerosol-forming substance 21 when it is empty.
- the second aerosol generation assembly 3 may be externally attached to the external casing 15 of the aerosol generation device 1.
- the second aerosol generation assembly 3 comprises an external casing 22 comprising coupling means cooperating with corresponding coupling means of the external casing 15 of the aerosol generation device 1.
- Such a variant allows the aerosol generation device 1 to be used with or without a second aerosol generation assembly 3.
- the second aerosol generation assembly 3 when the second aerosol generation assembly 3 is automatically activated by the first controller 16, additional electrical coupling means must be provided on the external casings 15 and 22 to allow the first controller 16 to send a triggering signal or command intended for activating the second aerosol generation assembly 3.
- the second aerosol generation assembly 3 comprises a dedicated button 20 fixed to its external casing 22 as illustrated in the non-limiting example of figure 2 , or a dedicated sub menu that can be selected through a user interface of the second aerosol generation assembly 3 (under control of its second controller 19).
- the second aerosol generation assembly 3 may comprise an exchangeable cartridge (or capsule or else container (or reservoir)) comprising at least one second aerosol-forming substance 21, or an exchangeable cartomizer comprising a cartridge comprising at least one second aerosol-forming substance 21 and possibly exchangeable.
- a cartomizer usually comprises a body comprising at least one cartridge (or reservoir), arranged for storing an aerosol-forming substance, a heater for aerosolizing or vaporizing this aerosol-forming substance to generate an aerosol, at least one air inlet, and an aerosol outlet.
- the second aerosol generation assembly 3 may comprise at least two second aerosol outlets 18, notably when it does not comprise its own second controller 19.
- the first controller 16 (or the possible second controller 19) may be arranged for selectively controlling access to these second aerosol outlets 18 to control the diffusion of the second aerosol (or scent) spatially and/or in intensity into the surroundings.
- the second aerosol generation assembly 3 may comprise as many flaps or valves 23 as second aerosol outlets 18, each flap or valve 23 controlling access to a corresponding second aerosol outlet 18 and being controlled by the first controller 16 or possibly by the second controller 19.
- Each flap or valve 23 has at least a totally closed position, a totally opened position, and possibly at least one partially opened position.
- the second aerosol generation assembly 3 may comprise at least two different second aerosol-forming substances 21 and at least two second aerosol outlets 18 associated respectively with these second aerosol-forming substances 21, for instance to avoid cross-contamination between the different second aerosols.
- the first controller 16 (or the possible second controller 19) may be arranged for controlling selectively access to these second aerosol outlets 18 to control diffusion of different second aerosols, generated respectively from the second aerosol-forming substances 21, into the surroundings.
- This embodiment may allow the user to select the scent or the mixing of scents to be released (or diffused).
- the second aerosol generation assembly 3 may comprise as many flaps or valves as second aerosol outlets 18, each flap or valve controlling access to a corresponding second aerosol outlet 18 and being controlled by the first controller 16 or possibly by the second controller 19.
- the (each) valve can be active or passive.
- the (each) valve can be passive (as a check valve) if enough internal pressure is created in the heating chamber to expel the scent. This internal pressure can be created by mechanical means (e.g a piston).
- the second aerosol outlet 18 can be designed as a spray nozzle. When the reservoir is opened, e.g. by mechanical actuation such as a pusher on a check valve, the substance is sprayed into a multitude of tiny droplets of scent.
- the (each) second aerosol-forming substance 21 may be a liquid (possibly with a water-based formulation) stored in a dedicated cartridge 25. But, this is not mandatory. Indeed, and as illustrated in the non-limiting example of figure 6 , the second aerosol generation assembly 3 may comprise at least one porous material 24 impregnated with a second aerosol-forming substance 21 and arranged for releasing a second aerosol (or scent) from its impregnated second aerosol-forming substance 21 when it is heated to a temperature greater than a threshold.
- the porous material is a zeolite material because it has a high capacity to absorb solvent-based aerosol-forming substance and a good heat retention.
- the solvent can be water and/or (an)other aerosol-forming agent(s), such as glycerine and/or propylene glycol (PG).
- PG propylene glycol
- the type of flavor (or scent) released by the second aerosol may be menthol, fruit, or berry, and may complement or alter the notes of the primary flavor of the first aerosol.
- the first aerosol can contain nicotine whereas the second aerosol does not.
- the heating of the first 12 and second 21 aerosol-forming substances may be independent one from the other or shared.
- the heating of the first 12 and second 21 aerosol-forming substances are independent. So, the first 2 and second 3 aerosol generation assemblies have respectively first 13 and second 26 heaters controlled separately and arranged for heating respectively the first 12 and second 21 aerosol-forming substances for generating respectively the first and second aerosols.
- the second heater 26 may surround a small part of the cartridge (or capsule or else container (or reservoir)) 25, comprising a second aerosol-forming substance 21, to heat the latter (21).
- the cartridge 25 could comprise a reservoir containing the second aerosol-forming substance 21 and a heating chamber fed with the second aerosol-forming substance 21 and comprising a transport element to transport the second aerosol-forming substance 21 from its reservoir to the heating chamber in the area comprising the second heater 26.
- this transport element may be a capillary element (possibly a capillary wick or mesh) having at least one feeding end.
- the second heater 26 may comprise a resistive coil wound around the capillary element, or an ohmic heater, such as an ohmic heating track printed on a surface of the transport element or a coil-and-wick assembly, or a thin film, or a micro-electronic-mechanical-system (or MEMS) having at least one microfluidic die and a heater arranged for heating liquid to force liquid through the die, or else may be an induction heater, for instance.

- the aerosol flow channel 29 comprises preferably a flap or valve 31 controlling its access or the access to the corresponding second aerosol outlet 18. This option allows preventing/authorizing release (or diffusion) of the scent via the second aerosol outlet 18.
- the flap or valve 31 can be controlled by the button 20 or by the first controller 16 or else by a solenoid activated by the first controller 16.
- the second heater 26 may be a coil associated with a susceptor or a resistive coil heater.
- the coil is arranged for generating an electromagnetic field when it is supplied with an electrical current, and the susceptor is arranged for transforming this electromagnetic field into heat.
- the second heater 26 could be located inside the cartridge (or capsule) 25.
- the second heater 26 is supplied with electrical energy originating from the first power source 14 (as illustrated in figures 4 and 5 ), or from a second power source 27 of the second aerosol generation assembly 3 (as illustrated in figures 1 and 2 ).

- the second controller (or control unit) 19 may comprise at least a processor and a memory arranged for performing operations for controlling at least the second aerosol generation assembly 3 (and notably the second heater 26) and also the second power source 27 during a possible charging session.
- this processor may be a digital signal processor (or DSP), or an application specific integrated circuit (ASIC), or else a field programmable gate array (FPGA). More generally, this processor may comprise integrated (or printed) circuits, or several integrated (or printed) circuits connected therebetween through wired or wireless connections.
- this memory may be a random access memory (or RAM). But it may be any type of device arranged for storing program instructions for the associated processor.
- the second controller (or control unit) 19 may be fixed onto a second printed circuit board (or PCB) 28 (housed in the external casing 15 or 22).
- the second controller (or control unit) 19 may also comprise, in addition to its processor and memory, an input interface, a mass memory (notably for storing intermediate data produced during its calculus and processing), and an output interface for delivering messages and instructions at least for controlling the second aerosol generation assembly 3 (and notably the possible second heater 26) and the electronic component(s) (such as switch(es)) supplying the electrical power (stored in the second power source 27).
- a mass memory notably for storing intermediate data produced during its calculus and processing
- an output interface for delivering messages and instructions at least for controlling the second aerosol generation assembly 3 (and notably the possible second heater 26) and the electronic component(s) (such as switch(es)) supplying the electrical power (stored in the second power source 27).
- the first 12 and second 21 aerosol-forming substances have a shared heating. So, only the first aerosol generation assembly 2 has a first heater 13 arranged for heating the first 12 and second 21 aerosol-forming substances for generating respectively the first and second aerosols. This allows to simplify the second aerosol generation assembly 3 because the latter (3) does not need to comprise a second heater.
- the first heater 13 may be arranged for heating the first 12 and second 21 aerosol-forming substances respectively to first and second temperatures. But this is not mandatory.
- the second aerosol generation assembly 3 comprises a cartridge (or capsule or else container (or reservoir)) 25 comprising a second aerosol-forming substance 21 and set in the vicinity of the first heater 13 to allow heating of this second aerosol-forming substance 21 to a temperature that is sufficient for inducing generation of a second aerosol (or scent).
- the second aerosol generation assembly 3 comprises a porous material 24 impregnated with a second aerosol-forming substance 21 and set in the vicinity of the first heater 13 to allow heating of this impregnated second aerosol-forming substance 21 to a temperature that is greater than the threshold and therefore sufficient for inducing generation of a second aerosol (or scent).
- the second aerosol generation assembly 3 may comprise an ultrasonic vibrating element configured to change the second aerosol-forming substance 21 into the second aerosol.
- the ultrasonic vibrating element may be a vibrating mesh nebulizer (such as the one described below) or a surface acoustic wave (or SAW) nebulizer.
- the external casing 15 comprises an internal chamber 35 in which a consumable 36 comprising the first aerosol-forming substance 12 can be introduced.
- this consumable 36 may be a tobacco stick.
- the first aerosol-forming substance 12 comprises tobacco and/or reconstituted tobacco material.
- the substance comprises homogenized tobacco material (i.e. reconstituted tobacco such as cast sheet, tobacco paper or laminated tobacco sheet) and one or more of tobacco lamina, cellulose fibre or flavor.

- the consumable 36 may comprise a filter 37, downstream of the first aerosol-forming substance 12.
- the consumable 36 is partly inserted into the internal chamber 35. But in a variant it could be fully inserted into the internal chamber 35.
- the first aerosol-forming substance 12 is heated by the first heater 13 that is supplied with electrical energy originating from the power source 14, in this non-limiting example.
- the first heater 13 surrounds the internal chamber 35, and therefore a part of the consumable 36 (and more precisely its first aerosol-forming substance 12) to heat the latter (12).
- the first heater 13 may be a thin film heater wrapped around the outer surface of the internal chamber 35 to heat its side walls and at least a part of its internal volume (which therefore defines a heating chamber).

- the first heater 13 could be located inside the consumable 36 or inside the internal chamber 35.
- the second aerosol generation assembly 3 may comprise a cartridge 25 comprising a reservoir containing the second aerosol-forming substance 21 and a nebulizer 40, for instance.
- the nebulizer 40 may be a mesh nebulizer comprising a piezo electric element 38 intended for oscillating a mesh 39 to pump the second aerosol-forming substance (here a liquid) 21 through this mesh 39.
- the size of the droplets is about twice the size of the holes of the mesh 39.
- the nebulizer 40 could be a jet nebulizer or an ultrasonic nebulizer.
- a jet nebulizer is based on a pressure container and a valve opening and closing, and requires a pressurized cartridge containing the second aerosol-forming substance 21. It is also recalled that an ultrasonic nebulizer has a transducer intended for oscillating the second aerosol-forming liquid 21 to change it to the second aerosol.
- the nebulizer 40 could be replaced with a scent diffuser based on a porous substrate containing scent oil (or second aerosol-forming substance 21) and activated by an activating mechanism.
- the nebulizer 40 could be replaced by a micro-electronic-mechanical-system (or MEMS) having at least one microfluidic die and a heater arranged for heating liquid to force liquid through the die.
