Aerosol generating device comprising a vaporizer

Abstract

An aerosol generating device includes a vaporizer configured to generate aerosol from an aerosol generating material, a medium accommodating portion in which a medium through which the aerosol generated by the vaporizer passes is accommodated, a path through which the aerosol generated by the vaporizer flows, and a chamber located between the path and the medium accommodating portion, having an inner diameter greater than an inner diameter of the path, and configured to deliver the aerosol supplied from the path to the medium accommodating portion.

1 . An aerosol generating device including a vaporizer comprising:
 a vaporizer configured to generate aerosol from an aerosol generating material;   a medium accommodating portion in which a medium through which the aerosol generated by the vaporizer passes is accommodated;   a path through which the aerosol generated by the vaporizer flows; and   a chamber located between the path and the medium accommodating portion, having an inner diameter greater than an inner diameter of the path, and configured to deliver the aerosol supplied from the path to the medium accommodating portion,   wherein a direction in which the path extends crosses a direction in which the medium accommodating portion extends.   
     
     
         2 . The aerosol generating device including a vaporizer of  claim 1 , wherein the inner diameter of the chamber is equal to or greater than 70% of an inner diameter of the medium accommodating portion. 
     
     
         3 . The aerosol generating device including a vaporizer of  claim 1 , wherein the chamber comprises:
 a chamber inlet through which the aerosol is received from the path; and   a chamber inclined surface formed opposite to the chamber inlet.   
     
     
         4 . The aerosol generating device including a vaporizer of  claim 1 , wherein the chamber comprises:
 a chamber inlet through which the aerosol is received from the path; and   a chamber curved surface formed opposite to the chamber inlet.   
     
     
         5 . The aerosol generating device including a vaporizer of  claim 1 , wherein the chamber comprises:
 a chamber inlet through which the aerosol is received from the path;   a chamber outlet through which the aerosol is delivered to the medium accommodating portion; and   a chamber lower space formed opposite to the chamber outlet,   wherein the chamber inlet is located between the chamber outlet and the chamber lower space in the direction in which the medium accommodating portion extends.   
     
     
         6 . The aerosol generating device including a vaporizer of  claim 1 , wherein the chamber comprises a chamber inlet through which the aerosol is received from the path,
 wherein at least a part of an inner surface of the chamber inlet is connected to an inner surface of the path in the direction in which the path extends.   
     
     
         7 . The aerosol generating device including a vaporizer of  claim 1 , wherein the chamber comprises a chamber outlet through which the aerosol is delivered to the medium accommodating portion,
 wherein an inner diameter of the chamber outlet is less than an inner diameter of the medium.   
     
     
         8 . The aerosol generating device including a vaporizer of  claim 1 , wherein the chamber comprises a chamber outlet through which the aerosol is delivered to the medium accommodating portion,
 wherein the medium accommodating portion comprises a protrusion protruding from an inner surface of the medium accommodating portion to support the medium.   
     
     
         9 . The aerosol generating device including a vaporizer of  claim 1 , further comprising an expansion chamber located between the chamber and the medium accommodating portion,
 wherein the chamber comprises a chamber outlet through which the aerosol is delivered to the expansion chamber,   wherein an inner diameter of the expansion chamber is greater than an inner diameter of the chamber outlet.   
     
     
         10 . The aerosol generating device including a vaporizer of  claim 1 , further comprising a medium insertion port through which the medium is inserted,
 wherein, when the medium is accommodated in the medium accommodating portion, at least a part of the medium protrudes outward from the medium insertion port.
