Aerosol-generating system comprising moveable cartridge

1. An aerosol-generating system, comprising:

a housing comprising an air inlet and an air outlet defining an air flow path therebetween;

a heater element; and

a cartridge moveably mounted in the housing and reversibly displaceable from a first position to a second position, the cartridge comprising a moveable plunger, a liquid storage portion configured to hold an aerosol-generating liquid, and an opening configured to deliver the aerosol-generating liquid,

wherein the cartridge is further configured to activate release of a portion of the aerosol-generating liquid through the opening, when the cartridge is moved by an airstream created between the air inlet and the air outlet within the housing.

2. The aerosol-generating system according to claim 1 , wherein the cartridge is a polymeric material.

3. The aerosol-generating system according to claim 1 , wherein the opening is a funnel-shaped opening.

4. The aerosol-generating system according to claim 3 , wherein the plunger has a shape that corresponds to the funnel-shaped opening of the cartridge.

5. The aerosol-generating system according to claim 1 , further comprising a resilient element configured to bias the cartridge in the first position.

6. The aerosol-generating system according to claim 5 , wherein the resilient element is a compression spring disposed between an outlet end of the housing and a pressure chamber.

7. The aerosol-generating system according to claim 1 , wherein the heater element is provided at a distal end of an aerosol forming chamber.

8. The aerosol-generating system according to claim 1 , further comprising a resilient element configured to bias the cartridge in the first position, such that the opening of the cartridge is pressed against the heater element.

9. The aerosol-generating system according to claim 1 , further comprising a self-centering structure disposed at a distal end of an aerosol forming chamber or on the heater element.

10. The aerosol-generating system according to claim 9 ,

wherein the cartridge further comprises a nozzle,

wherein the self-centering structure includes a conical portion, and

wherein the nozzle of the cartridge is seated on the self-centering structure when the cartridge is in the first position.

11. The aerosol-generating system according to claim 10 , wherein the self-centering structure comprises a release pin, the nozzle of the cartridge being slideably seated on the release pin and being configured to slide along the release pin from a closing position to a release position upon movement of the cartridge from the first position into the second position.

12. The aerosol-generating system according to claim 11 ,

wherein the nozzle includes a release end having a cylindrical shape, the release pin having a cylindrical shape that corresponds to an inner cross-section of the release end of the nozzle, and

wherein a central part of the release pin has an area with reduced diameter relative to another part of the release pin.

13. The aerosol-generating system according to claim 1 , further comprising actuation means for forcing the moveable plunger into the cartridge.

14. The aerosol-generating system according to claim 13 ,

wherein the actuation means comprises a coupling element that is sealingly coupled to the cartridge,

wherein the coupling element comprises a membrane and defines a pressure chamber between the membrane and the plunger, and

wherein the membrane is configured to be pushed inwardly upon movement of the cartridge from the first position to the second position.

15. The aerosol-generating system according to claim 14 , further comprising a stationary element against which the membrane is pressed upon movement of the cartridge from the first position to the second position,

wherein a pressure in the pressure chamber is increased upon pressing of the membrane, such that the plunger is moved into the cartridge and the portion of the aerosol-generating liquid is dispensed through the opening of the cartridge.

16. A process of manufacture of an aerosol-generating system, comprising:

providing a housing comprising an air inlet and an air outlet defining an air flow path therebetween;

providing a heater element disposed inside the housing; and

providing a cartridge and moveably mounting the cartridge in the housing such that the cartridge is reversibly displaceable from a first position to a second position, the cartridge comprising a moveable plunger, a liquid storage portion configured to hold an aerosol-generating liquid, and an opening configured to deliver the aerosol-generating liquid,

wherein the cartridge is further configured to activate release of a portion of the aerosol-generating liquid through the opening, when the cartridge is moved by an airstream created between the air inlet and the air outlet within the housing.
