Abstract

The present invention pertains to an aerosol transferring adapter for an aerosol generating device, comprising a liquid storage component and a mouthpiece. The liquid storage component comprises a liquid reservoir for holding a liquid used to generate an aerosol, an airflow channel leading through the liquid reservoir, and a connector fitting arranged around the airflow channel. The mouthpiece comprises at least two mouthpiece compartments being fluidly separated from each other and each leading from at least one mouthpiece inlet to at least one mouthpiece outlet, and a mouthpiece fitting arranged around the mouthpiece inlet and configured to be alignably connected to the connector fitting of the liquid storage component.

Claims

1. A mouthpiece (10b) for an aerosol generating device (100), comprising:

at least two mouthpiece compartments (9a;

9b;

9c;

9d) being fluidly separated from each other and each leading from at least one mouthpiece inlet (5a) to at least one mouthpiece outlet (8), and

a mouthpiece fitting (5) arranged around the mouthpiece inlet (5a), which mouthpiece fitting (5) is configured to be alignably connected to an aerosol generating device (100),

wherein at least one of the at least two mouthpiece compartments is provided with a flavorant, and

wherein the mouthpiece is alignable to selectively direct an airflow towards one of the two mouthpiece compartments in order to control a flavor of the aerosol.

2. The mouthpiece (10b) according to claim 1, wherein at least one of the at least two mouthpiece compartments (9a;

9b;

9c;

9d) comprises an aerosol modifying medium arranged therein.

3. The mouthpiece (10b) according to claim 2, wherein the aerosol modifying medium comprises a flavourant, tobacco, tobacco derivative(s) or a combination thereof.

4. The mouthpiece (10b) according to claim 2, wherein the aerosol modifying medium comprises a filtration material.

5. The mouthpiece (10b) according to claim 2, wherein the aerosol modifying medium comprises a moisturizing/drying pad.

6. The mouthpiece (10b) according to claim 2, wherein at least two of the mouthpiece compartments (9a;

9b;

9c;

9d) comprise different aerosol modifying mediums arranged therein.

7. An aerosol transferring adapter (10) for an aerosol generating device (100), comprising:

a liquid storage component (10a) comprising;

a liquid reservoir (11) for holding a liquid (11a) used to generate an aerosol, an airflow channel (2) leading from the liquid reservoir (11), and a connector fitting (3) arranged around the airflow channel (2); and

a mouthpiece (10b) according to claim 1, the mouthpiece fitting (5) being configured to be alignably connected to the connector fitting (3) of the liquid storage component (10a).

8. The aerosol transferring adapter (10) according to claim 7, further comprising:

at least one sealing ring (4) fitted between the connector fitting (3) and the mouthpiece fitting (5) fluidly sealing the interface between the liquid storage component (10a) and the mouthpiece (10b) against the environment.

9. The aerosol transferring adapter (10) according to claim 7, wherein the connector fitting (3) and the mouthpiece fitting (5) realize complementary snap-fit parts or interlocking clearances.

10. The aerosol transferring adapter (10) according to claim 7, wherein the mouthpiece (10b) is rotatable against the liquid storage component (10a), the rotation causing the airflow channel (2) to connect to a different compartment of the at least two mouthpiece compartments (9a;

9b;

9c;

9d) depending on the rotation position of the mouthpiece (10b).

11. The aerosol transferring adapter (10) according to claim 10, further comprising:

one or more alignment marks (7a;

7b) in the outer housing of the mouthpiece (10b) and/or the liquid storage component (10a) configured to indicate the rotation position of the mouthpiece (10b) to a user of the aerosol generating device (100).

12. An aerosol generating device (100), comprising:

an aerosol transferring adapter (10) according to claim 7; and

a heating element (102) coupled to the liquid reservoir (11) at a liquid interface (1) and configured to heat liquid (11a) in the liquid reservoir (11), thereby generating aerosol in the airflow channel (2).

13. The aerosol generating device (100) according to claim 12, further comprising:

an electrical power source (101) coupled to the heating element (102) and

configured to provide the heating element (102) with electrical energy.

14. The aerosol generating device (100) according to claim 13, further comprising:

a housing (103) enclosing at least the heating element (102) and the electrical power source (101).

15. A method (20) for transferring aerosol within an aerosol generating device (100) according to claim 1, the method comprising the steps of:

generating (21) aerosol by volatilizing compounds of a liquid composition in a liquid reservoir (11) of the aerosol generating device (100);

guiding (22) the generated aerosol to a mouthpiece (10b) of the aerosol generating device (100), the mouthpiece (10b) comprising at least two mouthpiece compartments (9a;

9b;

9c;

9d) being fluidly separated from each other and each leading from a mouthpiece inlet (5a) to a mouthpiece outlet;

aligning (23) the position of the mouthpiece (10b) with respect to the liquid reservoir (11); and

guiding (24) the generated aerosol through at least one of the mouthpiece compartments (9a;

9b;

9c;

9d) depending on the aligned position of the mouthpiece (10b) with respect to the liquid reservoir (11).
