Method and apparatus relating to electronic smoking-substitute devices

Abstract

An electronic smoking-substitute device 110 includes a tube containing a reservoir 310 containing a liquid. The liquid includes a substance to be inhaled by the user, for example a nicotine dilution. The device also has a heating element 320 , the heating element is a coil and is in direct contact with the reservoir 310 . A power source 340 is arranged to power the heating element.

1 . An electronic smoking-substitute device comprising a tube containing:
 a reservoir containing a liquid, the liquid comprising a substance to be inhaled by the user;   a heating element, the heating element being a coil and being in direct contact with the reservoir; and   a power source, arranged to power the heating element.   
   
   
       2 . A device as claimed in  claim 1 , in which the reservoir is not removable from the tube without dismantling other parts of the device or destroying the device. 
   
   
       3 . A device as claimed in  claim 1 , in which the power source is not rechargeable. 
   
   
       4 . A device as claimed in  claim 1 , in which the power source is connected directly to the heating element. 
   
   
       5 . A device as claimed in  claim 1 , in which the power source is sufficient to enable at least 600 inhalations of atomised liquid. 
   
   
       6 . A device as claimed in  claim 1 , in which the tube is a plastics material. 
   
   
       7 . A device as claimed in  claim 1 , in which the tube, reservoir, heating element and power source form a single unit. 
   
   
       8 . A device as claimed in  claim 1 , in which the reservoir and the heating element form a first part and the power supply forms a second part. 
   
   
       9 . A device as claimed in  claim 1 , further comprising a switch for activation of the heating element. 
   
   
       10 . A device as claimed in  claim 9 , wherein the switch is a push switch located on the external surface of the tube. 
   
   
       11 . A device as claimed in  claim 9 , wherein the switch is an internal switch activated by a user sucking on the device. 
   
   
       12 . A device as claimed in  claim 1 , wherein the heating element is directly integrated with the reservoir.
