Aerosol generating material discharge assembly, cartridge, and aerosol generating device

Abstract

An aerosol generating material discharge assembly includes a storage storing an aerosol generating material and including an air inlet through which external air is introduced, a chamber connected to the storage and configured to receive the aerosol generating material from the storage, and a pump configured to allow the external air to flow into the storage through the air inlet by transferring the aerosol generating material to the chamber.

What is claimed is: 
     
         1 . An aerosol generating material discharge assembly comprising:
 a storage storing an aerosol generating material and comprising an air inlet through which external air is introduced;   a chamber connected to the storage and configured to receive the aerosol generating material from the storage; and   a pump configured to allow the external air to flow into the storage through the air inlet by transferring the aerosol generating material to the chamber.   
     
     
         2 . The aerosol generating material discharge assembly of  claim 1 , further comprising an identification member arranged inside the storage and in contact with the aerosol generating material to be moved according to a remaining amount of the aerosol generating material. 
     
     
         3 . The aerosol generating material discharge assembly of  claim 2 , wherein the identification member comprises a distinguishable color. 
     
     
         4 . The aerosol generating material discharge assembly of  claim 2 , wherein the identification member is configured to press the aerosol generating material towards the chamber as air flows into the storage. 
     
     
         5 . The aerosol generating material discharge assembly of  claim 2 , further comprising:
 a guide groove arranged in any one of the storage and the identification member and configured to guide a movement of the identification member; and   a protrusion arranged on another one of the storage and the identification member and coupled to the guide groove.   
     
     
         6 . The aerosol generating material discharge assembly of  claim 2 , wherein the identification member is moved while in contact with an inner surface of the storage. 
     
     
         7 . The aerosol generating material discharge assembly of  claim 2 , wherein the identification member comprises a peripheral portion in contact with an inner surface of the storage and a central portion located on an inner side of the peripheral portion, and
 the central portion comprises a material with a higher density than the peripheral portion.   
     
     
         8 . The aerosol generating material discharge assembly of  claim 2 , wherein the identification member comprises a peripheral portion in contact with an inner surface of the storage and a central portion located on an inner side of the peripheral portion, and
 the peripheral portion comprises a material with a lower coefficient of friction than the central portion.   
     
     
         9 . The aerosol generating material discharge assembly of  claim 1 , further comprising an airflow passage connected to the chamber to allow penetration of the external air, and separated from the air inlet. 
     
     
         10 . The aerosol generating material discharge assembly of  claim 1 , wherein the pump comprises an inlet connected to the storage and an outlet connected to the chamber. 
     
     
         11 . The aerosol generating material discharge assembly of  claim 10 , wherein the pump is arranged inside the chamber comprising a wick into which the aerosol generating material is absorbed, and
 the outlet is connected to the wick.   
     
     
         12 . The aerosol generating material discharge assembly of  claim 10 , wherein the pump is arranged outside the storage and the chamber. 
     
     
         13 . The aerosol generating material discharge assembly of  claim 12 , further comprising a first sealing portion arranged between the inlet and the storage and configured to prevent the aerosol generating material from leaking to the outside of the storage. 
     
     
         14 . A cartridge comprising:
 the aerosol generating material discharge assembly of  claim 1 ;   a wick arranged inside the chamber and into which an aerosol generating material is absorbed; and   a heating portion arranged inside the chamber and configured to heat the aerosol generating material absorbed into the wick.   
     
     
         15 . An aerosol generating device comprising:
 the aerosol generating material discharge assembly of  claim 1 ;   a cartridge comprising the aerosol generating material discharge assembly, a wick arranged inside the chamber and configured to absorb the aerosol generating material, and a heating portion arranged inside the chamber and configured to heat the aerosol generating material absorbed into the wick;   a battery configured to supply power for operation of the pump; and   a processor configured to control the operation of the pump.
