Abstract

A non-burning type flavor inhaler includes a main body unit having the non-inhalation end; and a capsule unit configured to be attachable/detachable to/from the main body unit. The main body unit includes an aerosol source, an atomizer, and a power source. The capsule unit includes a solid flavor source, and a filter adjacent to the inhalation end side with respect to the flavor source. A part of an outer surface of the flavor source except a portion adjacent to the filter is covered with a predetermined film composed of an impermeable member. The main body unit is provided with a breaker for breaking the part of the predetermined film in a part adjacent to the capsule unit.

First claim

The invention claimed is:

1. A non-burning type flavor inhaler comprising:
a first portion including a power source;
a second portion including a heat source and an aerosol source;
a third portion including a flavor source; and
an aerosol path providing a path of an aerosol from the heat source to the flavor source;
wherein:
the second portion is provided on a mouth piece side of the first portion,
the third portion is provided on a mouth piece side of the second portion,
the aerosol path includes a first aerosol path provided on a side of the heat source and a second aerosol path provided on a side of the flavor source,
a partition member for partitioning the second portion and the third portion is provided between the second portion and the third portion, and
the partition member includes a through hole that forms a part of the second aerosol path.

2. The non-burning type flavor inhaler according to claim 1 , wherein:
the aerosol path extends in a predetermined direction from the first portion to the third portion, and
a cross-sectional area of the second aerosol path perpendicular to the predetermined direction is smaller than a cross-sectional area of at least a part of the first aerosol path perpendicular to the predetermined direction.

3. The non-burning type flavor inhaler according to claim 2 , wherein the part of the first aerosol path is a part where adjacent to the partition member.

4. The non-burning type flavor inhaler according to claim 1 , comprising:
a member provided on a mouth piece side of the third portion,
wherein the member includes openings each having a size for not passing through a material forming the flavor source.

5. The non-burning type flavor inhaler according to claim 1 , wherein the second portion is configured to be attachable/detachable to/from the first portion.

6. The non-burning type flavor inhaler according to claim 1 , wherein the third portion is configured to be attachable/detachable to/from the second portion.

7. The non-burning type flavor inhaler according to claim 1 , comprising:
a fourth portion having a mouth piece opening to provide the aerosol to a user, as a portion different from the third portion.

8. The non-burning type flavor inhaler according to claim 7 , wherein:
the aerosol path extends in a predetermined direction from the first portion to the fourth portion, and
a cross-sectional area of the mouth piece opening perpendicular to the predetermined direction is smaller than a cross-sectional area of the third portion at a downstream end of the aerosol path which is perpendicular to the predetermined direction.

9. The non-burning type flavor inhaler according to claim 1 , wherein the aerosol path is formed by an attachment of the third portion to the second portion.

10. The non-burning type flavor inhaler according to claim 1 , wherein:
the aerosol path extends in a predetermined direction from the first portion to the third portion, and
the third portion includes portions having different cross-sectional areas perpendicular to the predetermined direction.

11. The non-burning type flavor inhaler according to claim 1 , wherein the aerosol source is a liquid and the flavor sour is solid.

12. The non-burning type flavor inhaler according to claim 1 , wherein the aerosol source is formed of a liquid not containing a nicotine component.

13. The non-burning type flavor inhaler according to claim 1 , wherein:
an inner space of the third portion accommodates the flavor source and forms a path of aerosol generated from the heat source,
the third portion includes an upstream portion positioned at an upstream side of the path of aerosol and a downstream portion positioned at a downstream side of the path of aerosol, and
a cross-sectional area of the downstream portion is larger than a cross-sectional area of the upstream portion.

14. The non-burning type flavor inhaler according to claim 4 , wherein the member is a filter.

15. The non-burning type flavor inhaler according to claim 1 , wherein the third portion has a mouth piece opening to provide the aerosol to a user.

16. The non-burning type flavor inhaler according to claim 1 , wherein the partition member is provided at the second portion.
