Abstract

An aerosol-generating product for modulating the release of a flavor substances includes an aerosol product, a heating element having two stage heat supply bodies and a sealing element, a power source, a control module, and a housing. The aerosol product is provided with an aerosol-generating substrate and a flavor carrier, and the aerosol-generating substrate and the flavor carrier are respectively arranged in a space or range formed by the first heat supply body and the second heat supply body and are sealed and isolated from the outside through the sealing element. The present invention provides an aerosol-generating product and method for modulating the release of flavored substances. It has a separate structure for modulating flavored substances, and the release of external flavor substances is more uniform and stable; there is no air flow through the aerosol-generating substrate and the flavor carrier, and there is no convection heat transfer. The temperature of the heating device remains stable during the operation, and the aerosol release is more stable. At the same time, no power compensation is required, the power consumption of the heating element is stable, and the requirements for the power supply and the control module are lower, which reduces the cost of aerosol-generated product.

First claim

1 . An aerosol-generating product for modulating the release of flavored substances, comprising an aerosol product ( 4 ), a heating element ( 5 ), a power source ( 2 ), and a control module ( 3 ), characterized in that
an aerosol-generating substrate ( 41 ) and a flavor carrier ( 42 ) are provided at a front end of said aerosol product ( 4 ), an aerosol filtering section ( 43 ) is provided at a rear end of said aerosol product, a hollow aerosol extraction cavity ( 44 ) is provided inside the middle of the aerosol product, and a sidewall through hole ( 441 ) is provided on a side wall of the aerosol extraction cavity ( 44 ); said heating element ( 5 ) is a hollow cavity with an opening opened at one end thereof, a first heat supply body ( 52 ) for heating aerosol-generating substrates is arranged on a side wall of the heating element ( 5 ) close to a closing end, a second heat supply body ( 53 ) for heating the flavor carrier is arranged on the side wall of the heating element ( 5 ) close to the opening end, and a sealing element ( 51 ) is arranged at the closing end of the heating element ( 5 ) and/or a rear end of the second heat supply body ( 53 ); one end of said aerosol product ( 4 ) is detachably arranged within the heating element ( 5 ), the aerosol-generating substrate ( 41 ) and the flavor carrier ( 42 ) are respectively arranged in a space or range formed by the first heat supply body ( 52 ) and the second heat supply body ( 53 ) during the operation or the use of the aerosol-generating product and are sealed and isolated from the outside through the sealing element ( 51 ), and the sidewall through hole ( 441 ) is arranged at a rear end of the sealing element ( 51 ).

2 . The aerosol-generating product for modulating the release of flavored substances according claim 1 , characterized in that said aerosol-generating product further comprises a housing ( 1 ), said power source ( 2 ) and said control module ( 3 ) are disposed inside said housing ( 1 ), wherein said power supply source ( 2 ) is communicated with said control module ( 3 ), a cavity ( 11 ) is provided at one end of said housing ( 1 ), said heating element ( 5 ) is disposed in said cavity ( 11 ), and said heating element ( 5 ) is communicated with said control module ( 3 ).

3 . The aerosol-generating product for modulating the release of flavored substances according claim 1 , characterized in that the sidewall through holes ( 441 ) is communicated with the interior of the aerosol extraction cavity ( 44 ), the diameter of said sidewall through hole ( 441 ) is preferably 0.2-2 mm.

4 . The aerosol-generating product for modulating the release of flavored substances according claim 1 , characterized in that the aerosol-generating substrate ( 41 ) may be a tobacco substrate, an herbal substrate, or a chemical formula synthetic substrate.

5 . The aerosol-generating product for modulating the release of flavored substances according claim 1 , characterized in that said flavor carrier ( 42 ) is an aerosol-generating substrate carrying with flavored substances.

6 . The aerosol-generating product for modulating the release of flavored substances according claim 1 , characterized in that the flavor carrier ( 42 ) is an organic or inorganic material carrying with flavored substances, having a porous structure, moldable, and heat resistance properties.

7 . The aerosol-generating product for modulating the release of flavored substances according claim 1 , characterized in that the first heat supply body ( 52 ) is preferably at a temperature of 200-800° C. and the second heat supply body ( 53 ) is preferably at a temperature of 30-500° C.

8 . The aerosol-generating product for modulating the release of flavored substances according claim 3 , characterized in that the number of said sidewall through hole ( 441 ) are plural.

9 . A method of modulating the release of flavored substances of the aerosol-generating product according to claim 1 , characterized in that,
by controlling the power supplied to the heating element, the first heat supply body ( 52 ) of the heating element is raised to a first temperature and the second heat supply body ( 53 ) of the heating element is raised to a second temperature, wherein the first temperature and second temperature are selected such that the aerosol is continuously generated and the flavored substances is continuously released during the operation of the aerosol-generating product; when smoking, due to the presence of the sealing element, the external air does not flow through the aerosol-generating substrate and the flavor carrier, but directly enters into the interior of the aerosol-generating product through the sidewall through holes, and enters the consumer's mouth after mixing with the aerosol generated by the aerosol-generating substrate and the flavored substances released by the flavor carrier within the space or range formed by the aerosol extraction cavity ( 44 ).

10 . The aerosol-generating product for modulating the release of flavored substances and the method thereof according to claim 1 , characterized in that said front end refers to the end away from the consumer's mouth, and said rear end refers to the end near the consumer's mouth.
