Abstract

The portable essence vaporizer according to the present invention comprises a heat source for heating up an air flow which is passed through a substance from which the essence is to be extracted and is supplied to the user, and it comprises a heat exchanger which provides heat generated by the heat source to the air flow, and a thermal insulation which insulates the exterior from the heat source and the exchanger, said insulation being preferably microporous and having monolithic structures of metal oxides, amorphous silica or glass filaments, and the heat exchanger comprising an open cell foam structure; the vaporizer provides a satisfactory extraction and at the same time is of reduced size and has reduced electrical consumption.

Claims

1. A portable essence vaporizer for extracting an essence and supplying it to a user, which comprises a heat source for heating up an air flow which is passed through a substance from which one can extract an essence, and is supplied to a user, said vaporizer comprising a heat exchanger provided in such a way that the heat generated by the heat source is supplied to the air flow, and a thermal insulation for insulating the heat source and the heat exchanger from the exterior.

2. The vaporizer according to claim 1, wherein the thermal insulation comprises a nanoporous material with pores of a size of less than 50 nm.

3. The vaporizer according to claim 2, wherein the nanoporous material is microporous, with pores of a size of less than 2 nm.

4. The vaporizer according to claim 1, wherein the thermal insulation comprises monolithic structures of metal oxides, amorphous silica and glass filaments.

5. The vaporizer according to claim 1, wherein the heat exchanger comprises an open cell foam structure.

6. The vaporizer according to claim 5, wherein the open cell foam structure has a specific surface area of between 50 and 200 cm²/cm³.

7. The vaporizer according to claim 5, wherein the open cell foam structure is metallic.

8. The vaporizer according to any claim 5, wherein the open cell foam structure is ceramic.

9. The vaporizer according to claim 1, wherein the heat exchanger comprises a tubular piece, the heat source being provided at least partially inside the tubular piece.

10. The vaporizer according to claim 9, wherein the thermal insulation comprises a tubular element which at least partially surrounds the heat exchanger, the thermal insulation, tubular element and heat exchanger being housed within a casing which may be handled by a user.

11. The vaporizer according to claim 1, further comprising a duct for the circulation of the air flow, said duct comprising an extraction chamber for housing the substance being provided downstream of the heat source.

12. The vaporizer according to claim 11, further comprising a humidifier disposed in such a way that the air flow passes through it.

13. The vaporizer according to claim 12, wherein the humidifier is disposed downstream of the extraction chamber so that the air flow passes through it after extracting the essence.

14. The vaporizer according to claim 12, wherein the humidifier is disposed upstream of the extraction chamber, so that the air flow passes through it before extracting the essence.

15. The vaporizer according to claim 1, further comprising an inhalation nozzle through which a user inhales air so as to cause said air flow which passes through the substance from which the essence is to be extracted and which is inhaled by the user.

16. The vaporizer according to claim 15, wherein the inhalation nozzle comprises a first branch through which the air that is inhaled by the user passes and at least a second branch through which the air that is exhaled by the user passes.

17. The vaporizer according to claim 16, further comprising a vapor collector for filtering a vapor exhaled by the user after essence extraction.

18. The vaporizer according to claim 17, wherein the vapor collector comprises activated carbon.

19. Vaporizer according to claim 17, wherein the vapor collector comprises at least an entrance which is to be connected to a second branch of the inhalation nozzle and at least an exit which is to be open to the exterior.
