Aerosol Delivering System Comprising a Priming Bulb, and Cartridge and Aerosol Generating Device Comprising Such an Aerosol Delivering System

Abstract

An aerosol delivering system for an aerosol generating device and/or a cartridge is provided herein. The aerosol delivering system includes a main reservoir storing a liquid vaporisable material, a vaporising unit configured to vaporise the vaporisable material and a priming bulb arranged between the main reservoir and the vaporising unit.The priming bulb includes a bulb inlet connected to the main reservoir and a bulb outlet connected to the vaporising unit, and being configured, upon its actuating, to expel a predetermined quantity of vaporizable material from the bulb outlet and suck the same quantity of vaporizable material from the bulb inlet.

1 . An aerosol delivering system for an aerosol generating device and/or a cartridge, the aerosol delivering system comprising a main reservoir storing a liquid vaporisable material, a vaporising unit configured to vaporise the vaporisable material and a priming bulb arranged between the main reservoir and the vaporising unit,
 the priming bulb comprising a bulb inlet connected to the main reservoir and a bulb outlet connected to the vaporising unit, and being configured, upon its actuating, to expel a predetermined quantity of the liquid vaporizable material from the bulb outlet and suck an equal quantity of the liquid vaporizable material from the bulb inlet.   
     
     
         2 . The aerosol delivering system according to  claim 1 , further comprising a secondary reservoir arranged between the vaporising unit and the priming bulb, the secondary reservoir being connected to the bulb outlet. 
     
     
         3 . The aerosol delivering system according to  claim 2 , wherein the secondary reservoir defines an internal volume configured to receive the predetermined quantity of vaporisable material. 
     
     
         4 . The aerosol delivering system according to  claim 1 , wherein the predetermined quantity of vaporisable material corresponds to a dose of the vaporisable material for a single vaping session. 
     
     
         5 . The aerosol delivering system according to  claim 1 , wherein the priming bulb is configured to be actuated by a user before starting a vaping session. 
     
     
         6 . The aerosol delivering system according to  claim 1 , wherein the priming bulb comprises a housing defining an internal volume of the priming bulb. 
     
     
         7 . The aerosol delivering system according to  claim 6 , wherein the priming bulb further comprises an inlet valve allowing a flow passage from the bulb inlet to the internal volume of the priming bulb and an outlet valve allowing a flow passage from the internal volume of the priming bulb to the bulb outlet. 
     
     
         8 . The aerosol delivering system according to  claim 7 , wherein the inlet valve and the outlet valve are formed as one single piece. 
     
     
         9 . The aerosol delivering system according to  claim 8 , wherein said piece comprises a support part and a flexible part extending around the support part, the support part defining a through hole. 
     
     
         10 . The aerosol delivering system according to  claim 6 , wherein the housing of the priming bulb is made at least partially from an elastic material. 
     
     
         11 . The aerosol delivering system according to  claim 10 , wherein actuating the priming bulb corresponds to a compression of the housing of the priming bulb. 
     
     
         12 . The aerosol delivering system according to  claim 1 , wherein the bulb inlet and the bulb outlet are formed by two concentric conduits. 
     
     
         13 . A cartridge configured to operate with an aerosol generating device, the cartridge comprising the aerosol delivering system according to  claim 1 . 
     
     
         14 . An aerosol generating device comprising an aerosol delivering system according to  claim 1 .
