DESCRIPTION:
BRIEF SUMMARY
This application is the national phase under 35 U.S.C. .sctn.371 of prior PCT International Application No., PCT/JP97/01954, which has an International filing date of Jun. 9, 1996, which designated the United States of America, the entire contents of which are hereby incorporated by reference.
TECHNICAL FIELD
The present invention relates to a heater for heating a flavor generation piece in order to enjoy inhalation of a flavor and simulated smoking and a flavor generation instrument using the same and, more particularly, to a flavor generation heater and instrument used for generating a flavor as an inhalation target by heating a material and not by combustion.
BACKGROUND ART
A simulated smoking article employed for enjoying the flavor and smoke of tobacco without burning tobacco is already known, and various types of simulated smoking articles have been proposed.
Jpn. Pat. Appln. KOKAI Publication No. 3-232481 discloses a typical concept of a conventional simulated smoking article. The article of this reference uses, e.g., a rod-like solid material. When the solid material is heated by an electric heating element, an inhalation target, e.g., a flavor, is generated.
In the article utilizing such an electric heating element, if a power supply is incorporated in the article, the internal structure is complicated to increase the cost, and once the article causes a trouble, it is difficult to repair. In use of an external power supply, if the power supply and the smoking article are connected to each other with a cord, not only the location where the article can be used is limited, but also the cord becomes an obstacle. Inversely, if the article is formed such that it is removed from the external power supply when used for smoking, the heated state of the material can only be maintained until the user's inhalation (puffing) operation is complete about once or twice.
U.S. Pat. No. 4,945,931 discloses a simulated smoking article using a pressurized aerosol container. In the article of this reference, the puffing operation of the user swings the vanes to mechanically open the outlet port of the container, and the aerosol is emitted.
In the article utilizing such a pressurized flavor gas source, it is difficult to adjust the opening/closing valve such that the flavor gas can be emitted continuously. More specifically, in the article of this type, if the opening/closing vale is formed to have a simple structure, all of the pressurized flavor gas may undesirably be emitted until a puffing operation is complete twice or three times.
DISCLOSURE OF INVENTION
The present invention has been made in view of the above problems, and has as its object to provide a flavor generation heater and instrument which have a simple structure and enable continuous generation of a flavor.
According to the first aspect of the present invention, there is provided a heater for heating, without burning, a flavor generation piece, having an air intake port for taking in air therein and a suction port through which a user inhales a flavor and incorporating a material containing at least a flavor substance, thereby generating the flavor, characterized by comprising: extinction of the combustion portion; exhaust path; path, heat exchange being performed between a fluid flowing in the exhaust path and a fluid flowing in the air pipe; and generation piece.
According to the second aspect of the present invention, there is provided a heater for heating, from an outside of a heat conduction wall without burning, a material which is stored inside the heat conduction wall of a flavor generation piece and contains at least a flavor substance, thereby generating a flavor, the flavor generation piece having an air intake port for taking in air therein and a suction port through which a user inhales the flavor, characterized by comprising: extinction of the combustion portion; exhaust path; and flavor generation piece such that the heat conduction wall is located in the exhaust path.
According to the third aspect of the present invention, there
