  • the first and second flavour carrying units 9, 10 are easily exposable to the flow path 8 of the electronic smoking device 1 which extends from the heating element 4 to the mouthpiece 2. Therefore, a user can easily switch the flavour of the electronic smoking device 1 without having to open the device 1.
  • a recharge with flavoured material 11, 12 can easily be performed.
  • the first and second flavour carrying units 9, 10 may optionally be arranged in a rotatable or switchable member 13, wherein each of the flavour carrying units 9, 10 is selectively rotatable or switchable into the flow path 8. This provides for storing and using mutiple different flavoured materials 11, 12 in a compact but easily accessible manner.
  • the first and the second flavour carrying units 9, 10 may be formed as separate chambers 14 of a multiple chamber device 15 formed as a revolver drum.
  • the chambers 14 are spaced apart from each other.
  • the flavoured materials 11, 12 are then accommodated inside the separate chambers 14, wherein the chambers 14 are also permeable or substantially permeable to vaporized liquid 7.
  • the separate chambers 14 may be aligned with the opening provided in the cap part 32 so that they are separately exposed to the flow path 8. Therefore, a user can rotate a separate chamber 14 with a certain flavoured material 11, 12 into the flow path 8 in order to enjoy the flavour of the respective flavoured material 11, 12 without having to open the electronic smoking device 1.
  • a user can easily rotate the multiple chamber device 15 again in order to discard the currently used chamber 14 with the currently used flavoured material 11, 12 from the flow path 8 and to expose a different flavoured material 11, 12 contained in another chamber 14 to the flow path 8. If a flavoured material 11, 12 is exposed to the flow path 8 in a state in which the flow path 8 is substantially filled with vaporized liquid 7, the airflow of the flow path 8 is forced through the respective chamber 14 exposed to the flow path 8 and the flavoured material 11, 12 therein impregnates the passing vaporized liquid 7 with its respective flavour. Since only the liquid 7 is in contact with the heating element 4, there is no contamination or mixing of different flavours when the flavoured material 11, 12 consumed is changed.
  • the multiple chamber device 15 is exemplarily formed as a rotatable drum of a revolver which comprises four separate chambers 14.
  • Four flavoured materials are interposable within the four separate chambers 14 of the multiple chamber device 15.
  • only two of the four separate chambers 14 are filled.
  • other chamber devices 15 may have 3, 5, 6, 7, 8 or more separate chambers 14.
  • a second embodiment shown in Fig. 3 may be the same as the first embodiment shown in Fig. 1 , except that the electronic smoking device of Fig. 3 may have a substantially rod-shaped body portion 5 containing a heating element 4 and a reservoir 6.
  • the reservoir 6 for receiving liquid 7 is positioned on top of the body portion 5 facing towards the mouthpiece 2 of the electronic smoking device 1.
  • the reservoir 6 could instead be inserted into the body portion 5 (functioning as a housing) and protrude upwards from the body portion 5 thereby facing towards the mouthpiece 2 of the electronic smoking device 1.
  • the diameter of the reservoir 6 may be smaller than the diameter of the body portion 5.
  • the first and second flavour carrying units 9, 10 are exemplarily formed as two separate divisions 16 of a first multiple division disc 17.
  • the substantially cylindrical first disc 17 may be divided into multiple separate divisions 16 or compartments for holding a flavoured material 11, 12.
  • the multiple division disc 17 is divided into four congruent separate divisions 16.
  • the multiple division disc 17 may include 2, 3, 5, 6 or more different separate divisions 16, which also can be of different size.
  • the separate divisions 16 are preferably arranged to adjoin to one another. In such an embodiment, a plurality of different flavoured materials 11, 12 can compactly be stored or contained in a small device. This enables a small and compact realization of the electronic smoking device 1.
  • the electronic smoking device 1 may include a second multiple division disc 17 which is substantially identical to the first multiple division disc 17 in terms of shape and size, except that other flavoured materials 11, 12 are arranged within the separate divisions 16 of the second multiple division disc 17.
  • the first and second multiple division discs 17, if used, may be attachable to one another when they are aligned along a first axis 21 which intersects with the centre points of the first and second multiple division discs 17.
  • the separate divisions 16 of one disc 17 are arranged symmetrically to one another with respect to the first axis 21.
  • the first and second multiple division discs 17 may be attachable to one another via a press-fit connection or via other connection techniques.
  • two separate divisions 16 of the two discs 17 positioned directly above each other are selectively exposable to the flow path 8 at the same time when chosen for consumption by the user respectively. Therefore, the flavours of the flavoured materials 11, 12 contained in these two separate divisions 16 mix when the electronic smoking device 1 is used.
  • the two discs 17 may be rotatable on a common axle coincident with the first axis 21, with the axle fixed directly or indirectly onto the housing.
  • a user can choose the specific alignment of the first and second multiple division discs 17 by attaching the first and second multiple division discs 17 with each other thereby choosing a specific mix of the selected (i.e. aligned) flavoured materials 11, 12 arranged in the separate divisions 16 of the first and second multiple division discs 17 when the electronic smoking device 1 is in operation. In this way, it is up to the user to choose, which separate division 16 of the second multiple division disc 17 is positioned directly above which separate division 16 of the first multiple division disc 17, when attaching the first multiple division disc 17 to the second multiple division disc 17. However, it also possible to use only the first or only the second multiple division disc 17 for consumption, thereby not mixing the flavours of the flavoured materials 11, 12 contained within the separate divisions 16 of a multiple division disc 17. Additional discs may be used in the same way, such as a third and/or a fourth or higher number multiple division disc 17.
  • the electronic smoking device 1 may further include two moveable plates 18 which are configured to selectively modify the course of the flow path 8 inside the body portion 5, to guide the flow path 8 through a specific division 16 of a multiple division disc 17. Therefore, the multiple division discs 17 can be fixed to the body portion 5 of the electronic smoking device 1 and do not have to be moveably attached to it, thereby simplifying construction of the electronic smoking device 1.

  • the first and second moveable plates 18 have a circular shape and each plate 18 comprises a base portion 19 and at least one opening 20 formed in the base portion 19, defining the cross-section of the flow path 8.
  • the moveable plates 18 are each attachable to the multiple division discs 17 via a press-fit connection. However, it is also possible to realize embodiments of the present invention with moveable plates 18 which can be attached to the multiple division discs 17 via different attachment means which are not explicitly disclosed herein. Furthermore, it is also possible to realize embodiments of the present invention with at least one fixed plate that for example can have the shape as described hereinbefore and at least one moveable multiple division disc 17.
  • the first and second moveable plates 18 are rotatable around the first axis 21 and the opening 20 is spaced apart from said first axis 21. In more particular, a centre portion of the opening 20 is spaced apart from said first axis 21.
  • the flow path 8 can be altered around the first axis 21 of the moveable plate 18 thereby separately selecting different divisions 16 of the multiple division discs 17 which prevent a mixing of flavours from separate adjacent divisions 16 containing different flavoured materials 11, 12.
  • the base portions 19 of the moveable plates 18 are exemplarily congruent to three adjacent separate divisions 16 of a multiple division disc 17 of the second embodiment of the electronic smoking device 1 respectively, wherein the opening 20 is congruent to one separate division 16 of a multiple division disc 17 of the second embodiment of the electronic smoking device 1 respectively.
  • the base portions 19 functions as a barrier for an airflow thereby blocking and deflecting the flow path 8 to extend between the openings 20.
  • the flow path 8 is guided through the opening 20 of the first moveable plate 18, the exposed division 16 of the first multiple division disc 17 which is aligned with the opening 20 of the first moveable plate 18, the exposed division 16 of the second multiple division disc 17 which is aligned with the exposed division 16 of the first multiple division disc 17 and the opening 20 of the second moveable plate 18 which is aligned with the exposed separate division 16 of the second multiple division disc 17.
  • the course of the flow path 8 is shown as a dashed line in Fig. 3 .
  • Fig. 4 shows a schematic detailed view of an embodiment of a moveable plate 18 as used in the second embodiment of an electronic smoking device 1 according to the present invention.
  • Fig. 4 shows the interaction of a moveable plate 18 with the reservoir 6 and the liquid 7 contained therein.
  • the moveable plate 18 as shown in Fig. 4 is identical in terms of size and shape to the first moveable plate 18 of the second embodiment of the present invention as shown in Fig. 3 .
  • the liquid 7 is vaporized, it exits the first moveable plate 18 through the opening 20. Therefore, when the first moveable plate 18 is rotated around the first axis 21, the relative position of the opening 20 is altered which modifies the course of the flow path 8, whereby a specific separate division 16 of a multiple division disc 17 ( Fig.
  • a puff detector for detecting a user puffing on a device could be provided and the puff detector could be arranged to initiate the activation of an atomizer when a user puffed on the device
