Smoking substitute apparatus

Abstract

The present invention provides a smoking system apparatus ( 150 ) in which there is a valve ( 190 ) movable between an open position in which fluid flow from a reservoir to a vaporizer is permitted, and a closed position in which fluid flow from the reservoir to the vaporizer is prevented, the valve configured to move from the closed position to the open position upon engagement of the smoking system apparatus ( 150 ) with a main body ( 120 ) to form a smoking substitute system ( 110 ). Such a system is also provided by the present invention.

1 . A smoking system apparatus for engagement with a main body to form a smoking substitute system, the smoking system apparatus comprising:
 a reservoir for storing a liquid aerosol precursor,   a vaporizer in fluid communication with the reservoir for vaporizing aerosol precursor received from the reservoir, and   
       a valve movable between an open position in which fluid flow from the reservoir to the vaporizer is permitted, and a closed position in which fluid flow from the reservoir to the vaporizer is prevented, the valve configured to move from the closed position to the open position upon engagement of the smoking system apparatus with the main body, wherein the valve is magnetic or is formed of a magnetic material. 
     
     
         2 . (canceled) 
     
     
         3 . A smoking substitute system comprising:
 a smoking substitute apparatus comprising a reservoir for storing a liquid aerosol precursor, a vaporizer in fluid communication with the reservoir for vaporizing aerosol precursor received from the reservoir, and a valve movable between an open position in which fluid flow from the reservoir to the vaporizer is permitted, and a closed position in which fluid flow from the reservoir to the vaporizer is prevented; and   a main body comprising an engagement portion for releasable engagement with the smoking substitute apparatus, the engagement portion comprising a valve interaction element configured to cause the valve to move from the closed position to the open position upon engagement of the smoking substitute apparatus with the engagement portion.   
     
     
         4 . (canceled) 
     
     
         5 . A smoking substitute system according to  claim 3 , wherein either both the valve and the valve interaction element comprise magnets or one of the valve and the valve interaction element comprises a magnet and the other comprises a magnetic material. 
     
     
         6 . A smoking substitute apparatus according to  claim 1 , wherein the vaporizer is in fluid communication with the reservoir via a liquid supply passage when the valve is in the open position;
 the valve being positioned in the liquid supply passage and blocking it while in the closed position.   
     
     
         7 . A smoking substitute apparatus according to  claim 1 , wherein the vaporizer comprises a wick which is in fluid communication with the reservoir via a liquid supply passage when the valve is in the open position. 
     
     
         8 . A smoking substitute apparatus according to  claim 1 , wherein the valve is recessed inside the smoking substitute apparatus when in the closed position. 
     
     
         9 . A smoking substitute apparatus according to  claim 1 , wherein the valve extends from the smoking substitute apparatus, into a corresponding recess in the main body, when in the open position. 
     
     
         10 . A smoking substitute system according to  claim 3 , wherein the vaporizer is in fluid communication with the reservoir via a liquid supply passage when the valve is in the open position;
 the valve being positioned in the liquid supply passage and blocking it while in the closed position.   
     
     
         11 . A smoking substitute system according to  claim 3 , wherein the vaporizer comprises a wick which is in fluid communication with the reservoir via a liquid supply passage when the valve is in the open position. 
     
     
         12 . A smoking substitute system according to  claim 3 , wherein the valve is recessed inside the smoking substitute apparatus when in the closed position. 
     
     
         13 . A smoking substitute system according to  claim 3 , wherein the valve extends from the smoking substitute apparatus, into a corresponding recess in the main body, when in the open position.
