- the electric heater is provided with a plurality of apertures or through holes through which liquid may pass from the wick and be vaporized when the heater is activated.
- An open volume at the heater forms a vaporizing chamber.
- the wick is elongated and has an extension section extending outside the heater.
- Vapor generating device is enclosed in a housing together with a power supply and a control unit.
- a mouth piece In the delivery system, there is also a mouth piece and at least one channel or outlet conduit extending from the mouth piece to the vaporizing chamber.
- vaporized liquid present in the vaporizing chamber will be drawn through the at least one duct or outlet conduit to the mouth piece and to the user.
- the mouth piece is inserted into the housing.
- the housing is provided with at least one air inlet connecting vaporizing chamber with the exterior of housing.
- the invention relates to a method of using the system or method as defined above or below for the treatment of a human being a smoking addict, i.e., aid in quitting smoking.

- At least one air inlet 17 is provided and extends into an interior space within housing 46 .
- the invention in a first aspect, as shown in FIG. 2 to FIG. 4 , the invention relates to a vapor generating device 10 for generating a vapor from a liquid, wherein said liquid comprises nicotine or a salt thereof.
- the liquid is contained in a reservoir 14 supported inside said disposable cartridge 42 .
- the embodiments of a vapor generating device 10 shown in FIG. 2 and FIG. 3 comprise a base plate 11 and an elongated wick or similar liquid carrying element extending from base plate 11 inside a tube 30 .
- Tube 30 is hollow with an interior void formed as a central bore 26 in which a wick 24 is received.
- An electric heater 20 encloses a heater section 22 of the wick 24 and the tube 30 .
- Electric heater 20 and housing 46 cooperate to form a vaporization chamber 18 schematically shown in FIG. 2 .
- Electric heater 20 is formed with an interior opening arranged to receive tube 30 .
- a plurality of apertures 28 extends radially from the interior opening to the exterior of the electric heater 20 .
- tube 30 is rigid. Tube 30 is elongated and will enter reservoir 14 through a port 16 when cartridge 42 is inserted into housing 46 .
- Port 16 ensures that there is no leaking of fluid from reservoir 14 .
- At least one sponge 23 is provided inside reservoir 14 .
- Sponge 23 is soaked with liquid.
- electric heater 20 comprises an electrically resistive material embedded within a heat diffusing material.
- Rigid tube 20 comprises a material that allows to be heated by electric heater 20 to above 120° C.
- material of heater 20 withstands temperatures in interval 120° C. to 200° C.
- material of heater 20 withstands temperatures such as at least 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240 or 250° C.
- the rigid tube becomes heated and the liquid present within the openings of the rigid tube 20 becomes heated and vaporize. The vapor moves away towards the mouth piece and into the human being.
- a suitable plastic material can be used for the rigid tube.
- Base plate 11 isolates electric heater 20 from other thermally sensitive components of electronic delivery system 40 .
