Abstract

An aerosol-generating device is disclosed. The aerosol-generating device includes a housing; a cartridge disposed in the housing and including a first container and a second container which are rotatably coupled, wherein the second container includes a plurality of chambers which are isolated from each other; a dial gear disposed in the housing and configured to rotate about a rotating shaft parallel to a rotating shaft of the second container; and a cartridge gear coupled to the second container and engaged with the dial gear such that rotation of the dial gear causes rotation of the second container via the cartridge gear.

First claim

What is claimed is:

1 . An aerosol-generating device comprising:
a housing; a cartridge disposed in the housing and including a first container and a second container which are rotatably coupled, wherein the second container includes a plurality of chambers which are isolated from each other; a dial gear disposed in the housing and configured to rotate about a rotating shaft parallel to a rotating shaft of the second container; and a cartridge gear coupled to the second container and engaged with the dial gear such that rotation of the dial gear causes rotation of the second container via the cartridge gear.

2 . The aerosol-generating device according to claim 1 , wherein the cartridge gear is coupled to the second container via a projection projecting from an inner facing surface of the cartridge gear being engaged with a first second guide groove formed at an outer facing surface of the second container.

3 . The aerosol-generating device according to claim 2 , wherein the second guide groove is formed vertically along the outer facing surface of the second container and includes a portion which is wider toward a lower end.

4 . The aerosol-generating device according to claim 3 , wherein the first container includes a first guide groove formed vertically along an outer facing surface of the first container which is configured such that the first guide groove and the second guide groove are continuously aligned.

5 . The aerosol-generating device according to claim 1 , wherein the cartridge is disposed within a reception space of the housing configured to accommodate the cartridge therein, and
wherein an inner facing surface of the cartridge gear corresponds to a shape of a circumferential surface of the reception space, such that a continuous space is defined together by the inner facing surface of the cartridge gear and the reception space.

6 . The aerosol-generating device according to claim 1 , wherein the cartridge is configured such that one of the plurality of chambers of the second container is connectable to the first container via a passage while another of the plurality of chambers of the second container is closed.

7 . The aerosol-generating device according to claim 1 , wherein the plurality of chambers are arranged around the rotating shaft of the second container.

8 . The aerosol-generating device according to claim 1 , further comprising a dial coupled to the dial gear so as to be rotated therewith, wherein at least a portion of the dial is externally exposed from the housing.

9 . The aerosol-generating device according to claim 8 , wherein the dial is configured to rotate coaxially with the dial gear.

10 . The aerosol-generating device according to claim 8 , wherein an outer facing surface of the dial includes an concavo-convex portion formed thereon.

11 . The aerosol-generating device according to claim 10 , wherein the concavo-convex portion has a height lower than a height of gear teeth of the cartridge gear and a height of gear teeth of the dial gear.

12 . The aerosol-generating device according to claim 8 , wherein the dial is disposed at an upper portion of the housing.

13 . The aerosol-generating device according to claim 1 , wherein the cartridge is disposed within a reception space of the housing configured to accommodate the cartridge therein, and the aerosol-generating device further comprises:
a holding groove formed at an outer facing surface of the first container; and a holding protrusion which projects into the reception space and is configured to engage with the holding groove to secure the first container.

14 . The aerosol-generating device according to claim 1 , wherein the cartridge is disposed within a reception space of the housing configured to accommodate the cartridge therein, and the aerosol-generating device further comprises:
a fitting hole disposed at a bottom of the first container; and a fitting protrusion at a bottom of the reception space and configured to be inserted into the fitting hole.

15 . The aerosol-generating device according to claim 14 , wherein the fitting hole and the fitting protrusion are spaced apart from an axis extending from the rotating shaft of the second container.
