Vapour Generation Device Vaporisation Component

Abstract

A vaporisation component of a vapour generation device is provided. The vaporisation component comprises an evaporator component configured to generate a vapour flow by vaporising a vaporisable substance. The evaporator component has a first surface over which air flows in an airflow channel of a vapour generation device in a direction toward a mouthpiece. At least a portion of the first surface is non-flat with respect to the airflow channel so as to interfere with an airflow in the airflow channel and affect a distribution of droplets in the generated vapour flow.

1 . A vaporisation component of a vapour generation device, wherein the vaporisation component comprises:
 an evaporator component configured to generate a vapour flow by vaporising a vaporisable substance, the evaporator component having a first surface over which air flows in an airflow channel of the vapour generation device in a direction toward a mouthpiece, wherein at least a portion of the first surface is non-flat with respect to the airflow channel so as to interfere with an airflow in the airflow channel and affect a distribution of droplets in the generated vapour flow.   
     
     
         2 . The vaporisation component of  claim 1 , wherein the evaporator component further comprises one or more evaporator channels arranged therethrough to connect the first surface to a reservoir configured to store the vaporisable substance, and wherein the evaporator channels are configured to transport the vaporisable substance from the reservoir to openings in the first surface. 
     
     
         3 . The vaporisation component of  claim 2 , wherein the evaporator component is a block with one or more through-holes passing through the block to form the one or more evaporator channels arranged through the block. 
     
     
         4 . The vaporisation component of  claim 1 , wherein the non-flat portion of the first surface has a curved profile. 
     
     
         5 . The vaporisation component of  claim 4 , wherein the non-flat portion of the first surface comprises a plurality of curved profiles. 
     
     
         6 . The vaporisation component of  claim 4 , wherein the curved profile is curved in at least one dimension of the first surface. 
     
     
         7 . The vaporisation component of  claim 4 , wherein the curved profile is curved in two dimensions of the first surface. 
     
     
         8 . The vaporisation component of any one of  claim 4 , wherein the curved profile is substantially concave. 
     
     
         9 . The vaporisation component of any one of  claim 4 , wherein the curved profile is substantially convex. 
     
     
         10 . The vaporisation component of any one of  claim 4 , wherein the curved profile comprises convex and concave portions. 
     
     
         11 . The vaporisation component of  claim 1 , wherein the non-flat portion of the first surface linearly tapers inward to the airflow channel in a direction of the airflow, or wherein the first surface linearly tapers inward to the airflow channel in a direction opposite to the direction of the airflow. 
     
     
         12 . The vaporisation component of  claim 1 , wherein the first surface further comprises a plurality of recessed portions configured to interfere with the airflow in the airflow channel and affect the distribution of droplets in the vapour flow. 
     
     
         13 . The vaporisation component of  claim 1 , wherein the first surface has hydrophobic properties. 
     
     
         14 . The vaporisation component of  claim 1 , further comprising a reservoir configured to house the vaporisable substance, the reservoir being in connection with a second surface of the evaporator component, wherein the second surface is distinct from the first surface. 
     
     
         15 . A cartridge for use with a vapour generating device, the cartridge comprising the vaporisation component of  claim 1 . 
     
     
         16 . A vapour generating device comprising the vaporisation component of  claim 1 . 
     
     
         17 . A vapour generating device comprising the cartridge of  claim 15 .
