Smokeless flavor inhalator
A smokeless flavor inhalator includes a tobacco material as a flavor generator, and a heater for heating the tobacco material to allow flavor components to be released from the tobacco material while preventing smoke from being generated from the tobacco material. The heater has a carbon heat source and a cooling element. The carbon heat source and the cooling element cooperatively keep the heating temperature of the tobacco material at a temperature of 50 to 200° C.
1. A flavor inhalator comprising:
a heat source;
a tobacco material located downstream of the heat source;
a housing having a constant outer diameter and a constant inner diameter, the housing comprising:
a first section formed by a heat source holder attached to at least a part of the heat source and a second section,
wherein a peripheral wall of the heat source holder includes a first material including a first metal layer which constitutes an inner surface of the peripheral wall, a paper layer which is superposed on the first metal layer, and an incombustible material layer which is superposed on the paper layer, and
wherein the second section is formed of a second material different than the first material.
2. The flavor inhalator according to claim 1 , wherein the incombustible material layer is a second metal layer.
3. The flavor inhalator according to claim 1 , wherein the incombustible material layer is a ceramic layer.
4. The flavor inhalator according to claim 1 , wherein the incombustible material layer has a plurality of air inlet holes.
5. The flavor inhalator according to claim 4 , wherein the plurality of air inlet holes are located downstream of the heat source.
6. The flavor inhalator according to claim 4 , wherein the plurality of air inlet holes are arranged at intervals in a circumferential direction of the incombustible material layer.
7. The flavor inhalator according to claim 4 , wherein the plurality of air inlet holes are arranged in a circumferential direction of a segment of the tobacco material.
8. The flavor inhalator according to claim 1 , wherein the heat source need not have air permeability in order to prevent from inflow or outflow of a gas through the heat source.
9. The flavor inhalator according to claim 1 , further comprising an air impermeability material arranged adjacent to the heat source.
10. The flavor inhalator according to claim 9 , wherein the air impermeability material is interposed between the heat source and the tobacco material.
11. The flavor inhalator according to claim 1 , wherein at least one metal layer of the heat source holder extends to a segment of the tobacco material and transfers heat of the heat source to the tobacco material.
12. The flavor inhalator according to claim 1 , wherein at least one of the first metal layer and the incombustible material layer is made of an aluminum alloy.
13. The flavor inhalator according to claim 1 , wherein the paper layer is obtained from incombustible paper.
14. The flavor inhalator according to claim 1 , further comprising an air permeable stopper coupled to a downstream proximal end of a segment of the tobacco material.
15. The flavor inhalator according to claim 14 , wherein the air permeable stopper is made of a filter material.
16. The flavor inhalator according to claim 14 , further comprising a filter material coupled to downstream of the air permeable stopper.
17. The flavor inhalator according to claim 1 , further comprising a cool section coupled to downstream of the heat source; wherein the cool section includes passages through which aerosol generated from the flavor inhalator is able to pass.
18. The flavor inhalator according to claim 1 , further comprising a cool section coupled to downstream of the heat source; wherein the cool section has a total inner surface, which is able to contact aerosol generated from the flavor inhalator, as a heat exchange area of 500 mm 2 or more.
19. The flavor inhalator according to claim 1 , wherein the second section is a material holder surrounding the tobacco material.
20. The flavor inhalator according to claim 1 , further comprising a third section made of a different material than the first section and second section, wherein the second section is between the first section and third section.
