Abstract

Disclosed herein are methods and systems to vaporize extract, plant material containing organic material and the like utilizing convection heating via one or more manifolds each in fluid communication with a section of chamber containing organic material. The manifolds may be valved and may contain temperature sensors.

Claims

1. A portable vaporizer comprising:

a battery power supply;

a generally hollow body containing a manifold having an open top;

an intake fluidly communicating from the exterior of the body to the manifold;

a convection heating system comprising;

at least two heating elements each in thermal contact with the manifold;

at least one temperature sensor positioned in the manifold;

a controller in signal communication with the temperature sensor;

a chamber having a air permeable floor fluidly connected to the open top of the manifold;

an illumination communication display;

an on/off switch;

a cover that mates with the body above the chamber having a fluid pathway for vapor inhalation; and

,

wherein the controller controls the power supplied to each heating element in response to information it processes from the temperature sensor.

2. The vaporizer of claim 1 wherein the controller is in signal communication with the communication display.

3. The vaporizer of claim 1 further comprising at least one wall within the manifold to direct airflow.

4. The vaporizer of claim 3 further comprising a second temperature sensor within the manifold.

5. The vaporizer of claim 4 further comprising two zoned regions in the manifold each associated with a temperature sensor.

6. The vaporizer of claim 5 wherein the controller controls each heating element to tune the temperature of the air passing through each zone of the manifold.

7. The vaporizer of claim 1 further comprising:

a cover off sensor in signal communication with the controller; and

,

wherein the controller interrupts power to heating elements of the cover is off.

8. A vaporizer system comprising:

a controller;

a heating chamber having an open top surrounded by an annular wall and having a air permeable floor;

a manifold in thermal contact with at least two heating elements;

an intake to allow air to pass into the manifold;

an exit to allow heated air to pass out of the manifold;

an on/off switch;

a power supply;

a cover with an interface to close off the open top of the chamber;

an inhalation intake connected to a fluid pathway passing from inside the cover; and

,

wherein the power supply is electrically connected to the heating elements and the controller via the on/off switch; and

,

wherein each heating element is separately controlled by the controller.

9. The system of claim 8, further comprising at least one temperature sensor in thermal contact with the manifold connected to the controller and the controller in response to temperature sensor measurements adjusts the amount and/or timing of electricity provided to a turned on heating.

10. The system of claim 8 further comprising an illumination communications controlled by the controller.

11. The system of claim 8 further comprising a body surrounding at least the heating chamber.

12. The system of claim 11 further comprising an illumination communications system controlled by the controller visible from the exterior of the body.

13. The system of claim 8 wherein the controller at least one of monitors the amount of time a heating element is at a predetermined range of temperature and monitors when a predetermined time is met.

14. A vaporizing method, the method comprising:

placing organic plant material in a chamber;

connecting a manifold having a heater therein controlled by a control board connected to a battery supply to at least one valve whereby a fluid pathway for air is provided to the valve;

providing a fluid pathway from the valve to at least a portion of the chamber;

partially sealing the chamber with a cover having a fluid exit;

heating the air in the manifold to a predetermined temperature;

the user actuating the valve to open the fluid pathway;

the control board indicating to the user via an illumination communication that the users may inhale; and

, during inhalation at the fluid exit heated air from the first manifold passes through a predetermined section of the material in the chamber releasing vapor.
