Vapour Generation Device Vaporisation Component

Abstract

A vaporisation component of a vapour generation device includes 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. The first surface includes a plurality of recessed portions configured to interfere with an airflow in the airflow channel and affect a distribution of droplets in the generated vapour flow. The evaporator component further includes one or more evaporator channels arranged therethrough to connect the first surface to a reservoir configured to store the vaporisable substance. The evaporator channels are configured to transport the vaporisable substance from the reservoir to openings in the first surface.

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 a vapour generation device in a direction toward a mouthpiece, wherein the first surface comprises a plurality of recessed portions configured to interfere with an airflow in the airflow channel and affect a distribution of droplets in the generated vapour flow;   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.   
     
     
         2 . The vaporisation component of  claim 1 , wherein openings of the one or more evaporator channels are alternately arranged with the plurality of recessed portions in the first surface. 
     
     
         3 . The vaporisation component of  claim 1 , wherein the plurality of recessed portions include a plurality of dimples in the first surface. 
     
     
         4 . The vaporisation component of  claim 1 , wherein the recessed portions are hemispherical or substantially hemispherical in shape. 
     
     
         5 . The vaporisation component of  claim 1 , wherein each of the plurality of recessed portions is arranged to provide a circular airflow in the proximity of the respective recessed portion when air flows over the first surface. 
     
     
         6 . The vaporisation component of  claim 1 , wherein each of the plurality of recessed portions has a depth of 1 to 10 mm. 
     
     
         7 . The vaporisation component of  claim 1 , wherein at least a portion of the first surface is non-flat with respect to the airflow channel so as to interfere with the airflow in the airflow channel and affect the distribution of droplets in the generated vapour flow. 
     
     
         8 . The vaporisation component of  claim 7 , wherein the plurality of recessed portions are arranged in the non-flat portion of the first surface. 
     
     
         9 . The vaporisation component of  claim 7 , wherein the non-flat portion of the first surface has a curved profile. 
     
     
         10 . The vaporisation component of  claim 1 , wherein the first surface has hydrophobic properties. 
     
     
         11 . The vaporisation component of  claim 10 , wherein the hydrophobic properties are provided by a hydrophobic layer. 
     
     
         12 . The vaporisation component of  claim 1 , further comprising the reservoir configured to store the vaporisable substance, the reservoir being connected with a second surface of the evaporator component, wherein the second surface is distinct from the first surface. 
     
     
         13 . A cartridge for use with a vapour generating device, the cartridge comprising the vaporisation component of  claim 1 . 
     
     
         14 . A vapour generating device comprising the vaporisation component of  claim 1 .
