An Aerosol Generating Device, and Associated Aerosol Generating System

Abstract

An aerosol generating device extending along a device axis (Y) and configured to operate with an aerosol generating cartridge. The aerosol generating cartridge may include a cartridge body comprising a dispensing opening and a valve mounted on the dispensing opening. The aerosol generating device may include a heating cavity and a heater. The heating cavity may be configured to receive at least a part of the cartridge and defining a transversal wall. The heater may be integrated in the transversal wall of the heating cavity. The heater may include a flat part and a protruding part protruding from the flat part to face the valve when the cartridge is received at least partially in the heating cavity, the protruding part forming a substantially constant gap (d) with the cartridge when the cartridge is received at least partially in the heating cavity.

         2 . The aerosol generating device according to  claim 1 , wherein the protruding part of the heater has a shape configured to guide a vaporizable material dispensed through the valve, until the flat part. 
     
     
         3 . The aerosol generating device according to  claim 1 , wherein the protruding part of the heater has a triangular cross-section in at least one plane comprising the device axis (Y). 
     
     
         4 . The aerosol generating device according to  claim 1 , wherein the protruding part of the heater defines an edge extending along an axis parallel to the flat part of the heater. 
     
     
         5 . The aerosol generating device according to  claim 4 , wherein the protruding part of the heater further defines a pair of inclined surfaces extending from the edge to the flat part. 
     
     
         6 . The aerosol generating device according to  claim 4 , wherein the edge is designed to face a hole or a slit formed by the valve. 
     
     
         7 . The aerosol generating device according to  claim 1 , wherein the protruding part is arranged in a center of the flat part. 
     
     
         8 . The aerosol generating device according to  claim 1 , wherein the flat part has a substantially circular shape. 
     
     
         9 . The aerosol generating device according to  claim 1 , wherein the flat part comprises a border extending on its periphery and delimiting a receiving space for the vaporizable material. 
     
     
         10 . The aerosol generating device according to  claim 9 , wherein the receiving space is configured to receive a predetermined quantity of the vaporizable material. 
     
     
         11 . The aerosol generating device according to  claim 1 , wherein the flat part and the protruding part form one single piece. 
     
     
         12 . An aerosol generating system comprising:
 an aerosol generating device extending along a device axis (Y); and   an aerosol generating cartridge configured to operate with the aerosol generating device the aerosol generating cartridge comprising a cartridge body having a dispensing opening and a valve mounted on the dispensing opening, and   wherein the the aerosol generating device comprises:
 a heating cavity configured to receive at least a part of the cartridge and defining a transversal wall; and 
 a heater integrated in the transversal wall of the heating cavity, and 
   wherein the heater comprises a flat part and a protruding part protruding from the flat part to face the valve when the cartridge is received at least partially in the heating cavity, the protruding part forming a substantially constant gap (d) with the cartridge when the cartridge is received at least partially in the heating cavity.   
     
     
         13 . The aerosol generating system according to  claim 12 , wherein the valve comprises a movable part configured to be in an open configuration under pressure of the vaporizable material and in a closed configuration otherwise. 
     
     
         14 . The aerosol generating system according to  claim 13 , wherein the valve comprises a pair of lips arranged to face each other and forming between them a slit in the closed configuration of the moveable part and a hole in the open configuration of the moveable part. 
     
     
         15 . The aerosol generating system according to  claim 12 , wherein the aerosol generating cartridge extends along a cartridge axis (X) and comprises a cartridge body, and;
 wherein the cartridge body is deformable under pressure exerted according to the cartridge axis (X) to cause opening of the valve and dispensing of a vaporizable material through the valve.
