Aerosol-generating device
An aerosol-generating device is disclosed. The aerosol-generating device of the disclosure includes An aerosol-generating device comprising: a body; and a cartridge coupled to the body, the cartridge comprising: a first chamber configured to store liquid therein; an insertion space in communication with an outside of the cartridge; a second chamber in communication with the insertion space; a cartridge inlet through which the second chamber is in communication with the outside; a wick provided in the second chamber and configured to be in communication with the first chamber; and a heater configured to heat the wick, wherein the body comprises a column extending to be adjacent to the cartridge, and a first channel formed between the column and the cartridge allowing communication between the cartridge inlet and the outside.
1 . An aerosol-generating device comprising:
a body; and
a cartridge coupled to the body, the cartridge comprising:
a first chamber configured to store liquid therein;
an insertion space in communication with an outside of the cartridge;
a second chamber in communication with the insertion space;
a cartridge inlet through which the second chamber is in communication with the outside;
a wick provided in the second chamber and configured to be in communication with the first chamber; and
a heater configured to heat the wick,
wherein the body comprises a column extending to be adjacent to the cartridge, and a first channel formed between the column and the cartridge allowing communication between the cartridge inlet and the outside.
2 . The aerosol-generating device according to claim 1 , wherein the first channel corresponds to a recessed surface of the column facing the cartridge.
3 . The aerosol-generating device according to claim 2 , wherein the first channel extends along the column.
4 . The aerosol-generating device according to claim 1 , further comprising a sensor provided at the column configured to detect airflow.
5 . The aerosol-generating device according to claim 4 , wherein the first channel is one of a plurality of first channels, with the sensor disposed therebetween.
6 . The aerosol-generating device according to claim 1 , wherein the body comprises a mount having a space into which a lower portion of the cartridge is inserted, the column extending from one side of the mount, and
wherein the mount comprises:
a mount hole in communication with the cartridge inlet; and
a second channel formed at the mount and configured to allow communication between the first channel and the mount hole.
7 . The aerosol-generating device according to claim 6 , wherein the mount comprises:
a first bottom configured to support the lower portion of the cartridge and having the mount hole formed therethrough; and
a second bottom disposed below the first bottom, wherein the second channel is formed between the first bottom and the second bottom.
8 . The aerosol-generating device according to claim 7 , wherein the second channel corresponds to a recessed surface of at least one of the first bottom or the second bottom.
9 . The aerosol-generating device according to claim 7 , wherein the mount comprises a channel seal disposed between the first bottom and the second bottom and configured to seal the second channel.
10 . The aerosol-generating device according to claim 9 , wherein the channel seal is made of an elastic material.
11 . The aerosol-generating device according to claim 9 , wherein the cartridge comprises a cartridge inlet port surrounding the cartridge inlet and projecting downwards,
wherein the channel seal comprises a channel seal port extending through the first bottom to surround the mount hole, and
wherein the cartridge inlet port is inserted into the channel seal port.
12 . The aerosol-generating device according to claim 6 , further comprising:
a sensor provided at the column and configured to detect airflow; and
a third channel extending from the second channel to an inside of the column to a position of the sensor.
13 . The aerosol-generating device according to claim 12 , wherein the sensor is disposed at a position higher than the second channel.
14 . The aerosol-generating device according to claim 1 , wherein the cartridge comprises a chamber inlet port projecting upwards from a bottom of the second chamber and defining a chamber inlet allowing the second chamber to communicate with the cartridge inlet.
15 . The aerosol-generating device according to claim 14 , wherein a position of the chamber inlet is misaligned with a center of the wick.
