Abstract

A cartridge and an aerosol-generating device including the same are disclosed. The cartridge of the disclosure includes a first container comprising a first chamber configured to store a liquid; a second container coupled to the first container and comprising a second chamber; a wick disposed in the second chamber and in communication with the first chamber; a heater configured to heat the wick; a cartridge inlet formed at an outer wall of the second container; a connection passage formed in the second container and configured to provide a passage between the cartridge inlet and the second chamber; and a blocking wall formed in the connection passage and positioned in front of the cartridge inlet.

1 . A cartridge comprising:
 a first container comprising a first chamber configured to store a liquid;   a second container coupled to the first container and comprising a second chamber;   a wick disposed in the second chamber and in communication with the first chamber;   a heater configured to heat the wick;   a cartridge inlet formed at an outer wall of the second container;   a connection passage formed in the second container and configured to provide a passage between the cartridge inlet and the second chamber; and   a blocking wall formed in the connection passage and positioned in front of the cartridge inlet.   
     
     
         2 . The cartridge according to  claim 1 , wherein the cartridge inlet is formed at a position higher than a bottom of the connection passage. 
     
     
         3 . The cartridge according to  claim 1 , wherein the second container comprises:
 a lower case coupled to the first container; and   a frame accommodated in the lower case and configured to partition an inside of the lower case to define the second chamber and the connection passage,   wherein the frame comprises a chamber inlet allowing the second chamber to communicate with the connection passage.   
     
     
         4 . The cartridge according to  claim 3 , wherein the chamber inlet formed at a side wall of the frame at a position higher than a bottom of the second chamber. 
     
     
         5 . The cartridge according to  claim 3 , wherein the frame comprises:
 a lower wall forming a bottom of the second chamber and supported by a bottom of the lower case; and   the side wall extending upwards from the lower wall to define a side portion of the second chamber.   
     
     
         6 . The cartridge according to  claim 1 , wherein the blocking wall extends higher than a position of the cartridge inlet. 
     
     
         7 . The cartridge according to  claim 3 , wherein the blocking wall extends higher than a position of the chamber inlet. 
     
     
         8 . The cartridge according to  claim 3 , wherein the frame further comprises:
 a first frame portion configured to form a bottom of the first chamber and partition the first chamber from the connection passage; and   a second frame portion configured to partition an inside of the lower case into the connection passage and the second chamber, wherein the chamber inlet is formed at the second frame portion.   
     
     
         9 . The cartridge according to  claim 3 , wherein the frame further comprises a round surface defining a portion of the connection passage and disposed adjacent to an upper end of the blocking wall, wherein the round surface extends toward the chamber inlet. 
     
     
         10 . The cartridge according to  claim 9 , wherein the frame comprises:
 a first frame portion configured to form a bottom of the first chamber; and   a second frame portion configured to partition an inside of the lower case into the second chamber and the connection passage, wherein the chamber inlet is formed at the second frame portion, and   wherein the round surface is formed between the first frame portion and the second frame portion.   
     
     
         11 . An aerosol-generating device comprising:
 the cartridge described in  claim 1 ; and   a body configured to allow the cartridge to be coupled thereto.   
     
     
         12 . The aerosol-generating device according to  claim 11 , further comprising:
 a sensor mounted in the body and disposed adjacent to the cartridge inlet, wherein the sensor is configured to sense flow of air passing through the cartridge inlet.   
     
     
         13 . The aerosol-generating device according to  claim 12 , wherein the body comprises:
 a lower body; and   an upper body disposed above the lower body and comprising a mount configured to receive the second container,   wherein the mount comprises a sensor accommodation portion formed at a side wall of the mount and configured to accommodate the sensor therein.   
     
     
         14 . The aerosol-generating device according to  claim 13 , wherein the second container is positioned adjacent to the sensor accommodation portion.
