Abstract

An aerosol-generating device is disclosed. The aerosol-generating device includes a cartridge, which includes a first container and a second container includes a plurality of chambers isolated from each other, and is rotatably coupled to the first container, a housing, which has a reception space into which the cartridge is inserted, a dial gear, which is disposed in the housing, includes a rotating shaft parallel to a rotating shaft of the second container, and rotatably engages with the second container, and a battery, which is disposed in the housing adjacent both to the dial gear and to the reception space in a longitudinal direction of the rotating shaft of the dial gear.

First claim

What is claimed is:

1 . An aerosol-generating device comprising:
a cartridge including a first container and a second container, wherein the second container includes a plurality of chambers isolated from each other, and is rotatably coupled to the first container such that the plurality of chambers are rotatable relative to the first container; a housing, which has a reception space into which the cartridge is inserted; a dial gear, which is disposed in the housing, includes a rotating shaft parallel to a rotating shaft of the second container, and rotatably engages with the second container; and a battery, which is disposed in the housing adjacent both to the dial gear and to the reception space in a longitudinal direction of the rotating shaft of the dial gear.

2 . The aerosol-generating device according to claim 1 , wherein the battery is disposed at a lateral side of the reception space, and wherein the dial gear is disposed at the lateral side of the reception space and above the battery.

3 . The aerosol-generating device according to claim 1 , further comprising a cartridge gear, which is disposed in the housing to be coaxial with the second container, wherein an inner circumferential surface of the cartridge gear surrounds the reception space and engages an outer circumferential surface of the second container to rotate together with the second container, and wherein an outer circumferential surface of the cartridge gear engages the dial gear to rotate with the dial gear.

4 . The aerosol-generating device according to claim 3 , wherein the second container has a guide slit formed at an outer circumferential surface thereof, and wherein the cartridge gear includes an inner circumferential protrusion, which projects from the inner circumferential surface of the cartridge gear and into the guide slit.

5 . The aerosol-generating device according to claim 4 , wherein the guide slit extends in a longitudinal direction of the rotating shaft of the second container to vertically guide the cartridge along the inner circumferential protrusion.

6 . The aerosol-generating device according to claim 1 , further comprising a dial, which is disposed in the housing in the longitudinal direction of the rotating shaft of the dial gear to rotate together with the dial gear, wherein at least a portion of the dial is exposed to an outside of the housing.

7 . The aerosol-generating device according to claim 6 , wherein the dial is disposed at an upper portion of the housing.

8 . The aerosol-generating device according to claim 1 ,
wherein an outlet is at an upper portion of the second container to allow air to be discharged therethrough, wherein the aerosol-generating device further comprises: a container head, which is disposed over the second container around the outlet; and a mouthpiece, which is pivotably coupled to the container head and has a suction passage, wherein a seating portion corresponding to a depressed portion of an upper portion of the housing is positioned over the battery and has a shape corresponding to the mouthpiece, wherein the mouthpiece is seated in the seating portion to close the upper portion of the housing when the mouthpiece is pivoted to a first position, and the mouthpiece is separated from the seating portion to allow the suction passage to communicate with the outlet when the mouthpiece is pivoted to a second position.

9 . The aerosol-generating device according to claim 1 , further comprising:
a heater disposed in the first container; and a controller, which is disposed under the reception space and the battery in the housing, and is configured to control an operation of the heater.

10 . The aerosol-generating device according to claim 1 , further comprising a rotary switch, which is disposed over the battery and is configured to detect a position of the dial gear.

11 . The aerosol-generating device according to claim 1 , further comprising a flow sensor, which is disposed under the battery to face a side surface of a lower portion of the reception space, and is configured to detect a flow of air introduced into the cartridge.
