Abstract

Disclosed herein are aspects of portable vaporizers forming isolated vapor paths through vapor dispensers wherein a material chamber is part of a unitary furnace formed above a resistive heater and aliquots of heated air are drawn through plant-based material in the formed material chamber. A printed circuit board in signal communications with at least one temperature sensor controls the power flow to the resistance heater to select the temperature produced by heating elements in the furnace. A rechargeable battery power supply is mounted in a body to supply power the heating element.

Claims

1. A portable aromatherapy vaporizing system with unitary furnace and material chamber comprising:

a power supply (60);

a heating system comprising;

a unitary furnace (400) with an upper furnace (UF) and a lower furnace (LF) having an inside wall (429′

);

a material chamber (400″

) formed in the UF by dividing the unitary furnace with an air permeable screen (9501);

a heating element (405) inside the lower furnace;

a temperature sensor (90);

a controller (65) in signal communication with at least the sensor, heating element, power supply and on/off control (108A);

a floor gasket configured to hold the open bottom (400B) of the lower furnace

a floor configured to at least partially seal off the floor gasket;

a vent (117A) through at least one of the floor gasket, floor, and through the furnace (117B) providing a fluid connection for air to enter the furnace;

a connection interface gasket (CIG) (9000) providing a seal between the fluid pathway from the open top (400A) of the unitary furnace (400′

) and material chamber (400″

) to a vapor dispensing closing system (9200) having a top closure (9101);

a top portion cavity (9210) within the top closure; and

,

a fluid connection (9108) through the top closure in fluid connection with the top of the furnace.

2. The system of claim 1 further comprising:

a generally hollow body (6002) with an open top (103′

); and

,

the heating system and power supply are within the body.

3. The system of claim 2 wherein the dispensing closing system is configured to reversibly mate with the open top opening (103′

) of the body and forms an air tight seal therewith and a fluid pathway to the open top (400A) of the unitary furnace therewith.

4. The system of claim 2 wherein the temperature sensor is located inside the lower furnace near the floor.

5. The system of claim 2 further comprising a recess (6009) formed in a bottom region (104) of the body, the recess configured to accept insertion of an accessory module.

6. The system of claim 5 further comprising an accessory module configured to removably affix within at least part of the recess.

7. The system of claim 2 further comprising at least one illumination communication means (70/110) in signal communication with the control board which produces an illumination visible on the exterior of the body.

8. The system of claim 1 further comprising at least one airflow sensor (92) in signal communication with the controller.

9. The system of claim 1 further comprising a catch (9500) formed on the inside wall configured to mate with the air permeable screen.

10. The system of claim 2 wherein the top portion cavity is one of fit into the top closure (9101) and formed as part of the top closure.

11. The system of claim 2 wherein the fluid connection (9108) is configured temporarily sealed with the closure tab.

12. The system of claim 2 wherein the fluid connection is configured to reversibly mate with at least one of an inhalation member (9400) and a closure tab (9300).

13. The system of claim 12 wherein the closure tab forms a temporary odor seal with the fluid connection.

14. The system of claim 2 further comprising a sub chamber (900A) containing material is placed in the upper furnace and a flange (900B) catches the open top.

15. The system of claim 2 further comprising a sub chamber (900A) containing material is placed in the upper furnace and held via the air permeable screen.

16. A method to control vaporization in a portable aromatherapy system, the method comprising:

dividing a unitary furnace (400) with an air permeable screen (9501) between a lower furnace section (LF) and an upper furnace section (UF) forming a material section (400″

) having an open top (400A);

placing a resistive heater in the lower furnace section through a floor of the furnace;

monitoring the temperature near the floor with a temperature sensor in signal communication with a controller;

connecting a power supply in signal communication with the controller and whereby the power supply is switchable connected to the resistive heater;

moving an aliquot heated air through the unitary furnace and out of the open top;

moving an aliquot of air into the furnace through the floor into the open bottom (400B); and

,

whereby when the power supply is supplying power the controller is in signal communication with the temperature sensor and controls the amount of power supplied to the resistant heater corresponding to heating the air drawn into the furnace through at least one vent to a selected temperature.

17. The method of claim 16, the method further comprising:

temporarily sealing a portion of the top of the upper furnace with a vapor dispensing closing system (9200);

affixing an inhalation member to the vapor dispensing closing system forming an extended fluid pathway; and

,

inhaling through the inhalation member.

18. The method of claim 17 further comprising at least one illumination communication means in signal communication with the control board which produces an illumination corresponding to a state of the system.
