Abstract

A smoking device for generating and releasing smoking vapor free from contamination into the mouth of a user comprising a mouthpiece for providing vapor for inhalation to a user including a tubular casing containing a heater for heating a smoking substance at a substantially constant low temperature by regulating the flow of fuel by a thermal regulator and further having means for visual indication of the operation of the device.

Claims

1. A device for generating an inhalable vapor, the device comprising:

a casing comprising a heater having a vaporization chamber to hold a smokable material in a cartridge; and

a mouthpiece for use in connection with the casing, the mouthpiece comprising an air inlet for entry of fresh air into the casing and a hollow tube comprising an inhalation passage, the hollow tube extends into the vaporization chamber for releasing the inhalable vapor generated within the casing through the inhalation passage to a user.

2. The device of claim 1, wherein said air inlet is directed downwards.

3. The device of claim 1, wherein said air inlet is directed along a diagonal through the mouthpiece.

4. The device of claim 1, wherein said hollow tube comprises a puncturing means.

5. The device of claim 1, wherein the vaporization chamber is accessed through a door.

6. The device of claim 1, wherein the heater is electric or battery-powered.

7. The device of claim 1 further comprising a fuel source for the heater.

8. The device of claim 7 wherein the fuel source is butane.

9. The device of claim 7, wherein one or more of the fuel source, the mouthpiece and the cartridge are configured for removal from the device.
