Cartomizer for Vapor Generating Device and Vapor Generating Device

Abstract

A cartomizer for a vapor generating device includes: a liquid store, a vapor chimney, a heater disposed between the liquid store and the vapor chimney so that: vapor generating liquid coming from the liquid store, is first heated by the heater, so as to be changed to vapor then exiting from cartomizer by the vapor chimney, an absorbent element disposed at an interface between the heater and the vapor chimney: so as to absorb leakage at the interface, and so as to be removable from cartomizer, through the vapor chimney.

         2 . The cartomizer according to  claim 1 , wherein:
 the vapor chimney has:
 a first open end opening outside of the cartomizer, and 
 a second open end at the interface between the heater and the vapor chimney, and 
   the absorbent element is an absorbent pad disposed:
 at the second open end of the vapor chimney. 
   
     
     
         3 . The cartomizer according to  claim 2 , wherein the absorbent pad fills more than 75% of a cross-section of the second open end of the vapor chimney. 
     
     
         4 . The cartomizer according to  claim 2 , wherein:
 the absorbent pad is disposed:
 away from an external surface of the heater located at the interface between the heater and the vapor chimney, so as not to be in contact with the external surface of the heater, and 
 still sufficiently close to the external surface of the heater so as to absorb an e-liquid droplet located on or forming on the external surface of the heater. 
   
     
     
         5 . The cartomizer according to  claim 4 , wherein:
 the absorbent pad is located at a distance from the external surface of the heater,
 the distance being from 0.5 mm to 2 mm. 
   
     
     
         6 . The cartomizer according to  claim 2 , wherein:
 the absorbent pad has a cross section value of at least 90% of a cross section value of the vapor chimney,   or, the vapor chimney being cylindrical, the absorbent pad being cylindrical, the absorbent pad has a diameter value of at least 95% of a diameter value of the vapor chimney.   
     
     
         7 . The cartomizer according to  claim 2 , wherein:
 the absorbent pad has a square height value which is less than a cross section value of the absorbent pad,   or, the absorbent pad being cylindrical, the absorbent pad has a height value which is less than a diameter value of the absorbent pad.   
     
     
         8 . The cartomizer according to  claim 2 , wherein:
 the heater is a wick and coil heater, and   the absorbent element is disposed at an interface between the coil and the vapor chimney.   
     
     
         9 . The cartomizer according to  claim 8 , wherein:
 the absorbent pad is disposed:
 away from an external surface of the coil located at the interface between the coil and the vapor chimney, so as not to be in contact with the external surface of the coil, and 
 still sufficiently close to the external surface of the coil so as to absorb an e-liquid droplet located on the external surface of the coil. 
   
     
     
         10 . The cartomizer according to  claim 1 :
 further comprising a protective cover of the vapor chimney,   and wherein the absorbent element is disposed at the interface between the heater and the vapor chimney,
 so as to be removable from the cartomizer, through the vapor chimney, by a user of the vapor generating device when removing the protective cover. 
   
     
     
         11 . The cartomizer according to  claim 1 :
 further comprising a protective cover plugging the vapor chimney,   and wherein the absorbent element is secured to the protective cover so as to be removable from the cartomizer simultaneously with the protective cover.   
     
     
         12 . The cartomizer according to  claim 11 , wherein:
 the protective cover comprises an extension:
 which protrudes into the vapor chimney,
 at and end of which is secured the absorbent element. 
 
   
     
     
         13 . The cartomizer according to  claim 10 , wherein:
 the protective cover comprises a cap fitting onto the cartomizer, the cap:
 sealing the vapor chimney, 
   and wherein:   the cap is:
 spherical, 
 and/or made of silicone. 
   
     
     
         14 . The cartomizer according to  claim 1 , wherein:
 the vapor chimney is elongated or cylindrical,   the heater is elongated or cylindrical, and   the vapor chimney being orthogonal to the heater, or the vapor chimney and the heater being disposed relative to each other so as to make a T.
