Aerosol-generating device

Abstract

An aerosol-generating device is disclosed. The aerosol-generating device includes a body formed to be elongated and including an opening formed in one end thereof in a longitudinal direction, a cartridge accommodated in an accommodation space in the body through the opening, a guide groove formed by a portion of a side surface of the body being open and extending from the opening in the longitudinal direction of the body, a slit formed by a portion of a side surface of the cartridge, accommodated in the accommodation space, being recessed, and a rib protruding inward from the body and engaged with the slit. The rib extends in the extending direction of the guide groove and is positioned adjacent to the guide groove in the circumferential direction of the body.

What is claimed is: 
     
         1 . An aerosol-generating device comprising:
 a body formed to be elongated, the body comprising an opening formed in one end thereof in a longitudinal direction;   a cartridge accommodated in an accommodation space in the body through the opening;   a guide groove formed by a portion of a side surface of the body being open, the guide groove extending from the opening in the longitudinal direction of the body;   a slit formed by a portion of a side surface of the cartridge, accommodated in the accommodation space, being recessed; and   a rib protruding inward from the body and engaged with the slit,   wherein the rib extends in an extending direction of the guide groove and is positioned adjacent to the guide groove in a circumferential direction of the body.   
     
     
         2 . The aerosol-generating device according to  claim 1 , wherein the rib comprises:
 a first rib disposed adjacent to one side of the guide groove in the circumferential direction of the body; and   a second rib disposed adjacent to an opposite side of the guide groove in the circumferential direction of the body and facing the first rib, and   wherein the slit comprises:   a first slit engaged with the first rib; and   a second slit engaged with the second rib.   
     
     
         3 . The aerosol-generating device according to  claim 1 , wherein the cartridge comprises:
 a cartridge body having a storage chamber provided therein; and   a guide body protruding outward from a side surface of the cartridge body, extending in a longitudinal direction of the cartridge, and coupled to the guide groove.   
     
     
         4 . The aerosol-generating device according to  claim 3 , wherein the slit is elongated along a boundary between the cartridge body and the guide body and is positioned adjacent to the boundary. 
     
     
         5 . The aerosol-generating device according to  claim 1 , comprising a rib groove formed by a portion of the rib being recessed in an outward direction of the body and disposed adjacent to the opening. 
     
     
         6 . The aerosol-generating device according to  claim 5 , comprising a support protrusion formed in the slit, protruding outward from a side surface of the cartridge, and engaged with the rib groove. 
     
     
         7 . The aerosol-generating device according to  claim 6 , wherein the rib groove extends in the longitudinal direction of the body, and wherein the support protrusion extends in a longitudinal direction of the cartridge. 
     
     
         8 . The aerosol-generating device according to  claim 6 , comprising:
 a fixing groove formed by a portion of an inner surface of the body being recessed and extending in the circumferential direction of the body; and   a fixing protrusion protruding outward from a side surface of the cartridge, extending in a circumferential direction of the cartridge, and engaged with the fixing groove.   
     
     
         9 . The aerosol-generating device according to  claim 8 , wherein the fixing groove comprises a plurality of fixing grooves spaced apart from each other in the circumferential direction of the body, and
 wherein the fixing protrusion comprises a plurality of fixing protrusions engaged with each of the plurality of fixing grooves.   
     
     
         10 . The aerosol-generating device according to  claim 8 , wherein, in the longitudinal direction of the body, the rib groove is positioned closer to the opening than the fixing groove. 
     
     
         11 . The aerosol-generating device according to  claim 8 , wherein the rib groove is spaced apart from the fixing groove in the circumferential direction of the body. 
     
     
         12 . The aerosol-generating device according to  claim 8 , wherein an extending direction of the rib groove intersects with an extending direction of the fixing groove. 
     
     
         13 . The aerosol-generating device according to  claim 1 , wherein the slit comprises:
 a first end positioned adjacent to an upper end of the cartridge and covered by an upper surface of the cartridge; and   a second end formed to be open toward a lower end of the cartridge and having a width gradually increasing toward a lower side.   
     
     
         14 . The aerosol-generating device according to  claim 1 , comprising a mouthpiece protruding from one side of the cartridge and having a suction port provided therein,
 wherein an extending direction of the rib corresponds to a protruding direction of the mouthpiece.
