An Aerosol Generating System and Device Including a Liquid Capsule and a Holder with a Heater

Abstract

An electronic cigarette system including a liquid capsule having a reservoir for holding vaporizable material, a holder-facing surface, a vapor pipe with an vapor inlet at the holder-facing surface, an inhalation opening, a liquid exit port arranged at the holder-facing surface, and a capsule holder for removably receiving the liquid capsule. The capsule holder including a capsule accommodating opening, a heating device, and a mesh for being soaked with the vaporizable material. When the liquid capsule and the capsule holder are interconnected to each other, a fluid chamber is formed between an outer surface the capsule accommodating opening and the holder-facing surface and when the liquid capsule and the capsule holder are interconnected to each other, a fluidic connection path is formed from the reservoir to the fluid chamber via the liquid exit port, to reach the inhalation opening.

         3 . The electronic cigarette system of  claim 1 , wherein the heating device includes a first heating element for heating at a temperature T 1 , a second heating element for heating at a temperature T 2 , the first heating element arranged upstream along the fluidic connection path as compared to the second heating element-, wherein T 2 >T 1 . 
     
     
         4 . The electronic cigarette system of  claim 3 , wherein the first heating element includes a plate-like shaped heater arranged at the bottom wall of the capsule accommodating opening, and the second heating element includes a ring-shaped heater arranged around the conically-shaped side wall of the capsule accommodating opening. 
     
     
         5 . The electronic cigarette system of  claim 1 , wherein the capsule holder includes a valve opening device for opening the liquid exit port when the liquid capsule is connected to the capsule holder. 
     
     
         6 . The electronic cigarette system of  claim 2 , wherein the wicking element is arranged at the second conically-shaped side wall of the liquid capsule,
 wherein when the liquid capsule and the capsule holder are interconnected to each other, the conically-shaped side wall of the capsule holder and the conically-shaped side wall of the liquid capsule exert a compressive force to the wicking element.   
     
     
         7 . The electronic cigarette system of  claim 1 , further comprising:
 a sealing element arranged between the liquid capsule and the capsule holder.   
     
     
         8 . The electronic cigarette system of  claim 1 , wherein the capsule holder includes an air inlet channel in fluidic communication with an external environment and the fluid chamber. 
     
     
         9 . The electronic cigarette system of  claim 1 , wherein the liquid capsule includes a turnable ring configured to open and close a fluidic communication between liquid exit ports and the fluid chamber. 
     
     
         10 . An electronic cigarette system comprising:
 a first element having a liquid container for holding vaporizable material, a vapor pipe that is configured to at least partially traverse the liquid container, and a liquid exit port; and   a second element including an opening for receiving the first element, a mechanism for opening the liquid exit port, and a heater; and   a wicking element for being soaked with vaporizable material,   wherein the mechanism for opening the liquid exit port is configured to open the liquid exit port when the first element is placed into the opening of the second element, and   wherein the opening of the second element has a conical surface, and the heater is configured to heat the conical surface of the opening.   
     
     
         11 . The electronic cigarette system of  claim 10 , wherein the heater includes a circular heating device arranged around the conical surface, and the heater is configured to match with a position of the wicking element of the second element. 
     
     
         12 . The electronic cigarette system of  claim 10 , wherein at least one of the first and the second element includes a connection mechanism for removable interconnection of the first element with the opening of the second element. 
     
     
         13 . The electronic cigarette system of  claim 13 , wherein the interconnection of the first and the second element exerts a compressive force on the wicking element by the conical surface.
