Abstract

Efficient Heating of a consumable containing tobacco (or other plant material) without combustion using multiple induction heating zones for smoke free release of pant resins for use with tobacco or cannabis , including utilizing a removable cartridge which may contain metal foil regions. The cartridge is placed removably into a guide wherein heating occurs in zones via conductive and/or inductive heating elements. Such heat being at a sufficient temperature to vaporize resins or oils on plant material such as hemp, tobacco and cannabis , for inhalation from the cartridge.

Claims (35)

1. A vaporizer zoned heating system comprising:

a case configured to contain heating elements, power supply and controller;

a controller;

a power supply in signal communication with the controller;

two separately controlled heating elements each affixed cross-sectionally around a portion of a chamber configured as a cartridge guide;

wherein each heating element is in signal communication with the controller;

at least one temperature sensors in thermal communication with at least one of an outer and an inner wall of the cartridge guide and in signal communication with the controller;

a cartridge having an inhalation end and a containment end configured to fit within the cartridge guide and be in thermal communication with the heating elements;

the containment end including a metal layer and configured to hold material; and,

wherein the controller is configured to initiate heating when said cartridge is inserted into the receivor.

2. The vaporizer system of claim 1 , wherein the containment end is a combination of materials including at least paper and foil.

3. The vaporizer system of claim 1 , wherein the heating of the containment end is by conduction.

4. The vaporizer system of claim 1 , wherein the heating of the containment end is by induction.

5. The vaporizer system of claim 1 , wherein the material is tobacco.

6. The vaporizer system of claim 1 , wherein the metal is a foil.

7. The vaporizer system of claim 6 , further comprising the portion of foil closest to the active heating element heats up more than foil remote from the active heating element.

8. The vaporizer system of claim 1 , wherein the controller receives temperature sensor input and controls the timing and/or the amount of power applied to the activate heating element.

9. The vaporizer system of claim 8 , wherein the controller sequentially switches activated heating elements based on at least one of time and temperature.

10. The vaporizer system of claim 9 , wherein power consumption to heat one zone is less than the power needed to heat both zones at once.

11. A method of heating a containment end of a cartridge, the method including:

forming an elongated cartridge with an inhalation end and a containment end;

placing metal layer around the containment end of the cartridge;

placing tobacco to vaporize within the containment end;

wrapping an outer annular wall of a cartridge guide cross sectionally with two separated and separately controlled heating elements;

connecting the heating elements to a controller configured to control the power supplied to each heating element;

inserting the containment end of the cartridge into an interface having a seal and which opens into the cartridge guide;

wherein the cartridge guide is configured to leave the inhalation end outside of the interface;

if the controller determines a cartridge is in the receivor then the controller initiates sequential heating of zones via supplying power to the heating elements;

the controller heats at least one of the cartridge guide and the metal around the containment end.

12. The method of claim 11 , the method further comprising the controller receives temperature sensor input and controls the sequence of activating heating elements and the amount of power applied to each heating element.

13. The method of claim 11 , wherein the metal is foil.

14. The method of claim 13 , wherein the portion of foil closest to the active heating element heats up more than foil remote from the active heating element.

15. The method of claim 12 , wherein the controller sequentially activates one heating zone at a time based on at least one of time and temperature.

16. The method system of claim 15 , wherein sequential heating of zones reduces overheating of the containment end.

17. The method of claim 13 , wherein the heating of the containment end is by induction.
