Aerosol generating product capable of controlling the release of flavor substances, and method thereof.

Abstract

The aerosol product capable of regulating the release of flavor substances comprises an aerosol article 4, a heating element having a two-stage heat source body and a sealing element 51, a power source 2, a control module 3, and a housing 1. The aerosol article 4 is provided with an aerosol-generating substrate 41 and a flavor carrier 42, which are respectively disposed in a space or area formed by a first heat source body 52 and a second heat source body 53, and are sealed and isolated from the outside by a sealing element 51. The article has an independent flavor substance regulating structure, and the flavor substance is released more uniformly and stably. Since the air flow does not flow through the aerosol-generating substrate and the flavor carrier, there is no convective heat exchange, the temperature of the heating device remains stable within the working interval, and the aerosol release is more stable. Furthermore, no power compensation is required, the power consumption of the heating element is stable, the requirements for the power source and the control module are low, and the cost of the aerosol product is reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of tobacco aerosol generation, and particularly to an aerosol generation product for adjusting the release of flavor substances and a method thereof.

Background Art

[0002] Since the purpose for which consumers consume cigarette products is the most direct, the quality of cigarette smoke is an important factor in determining the quality of cigarette products. The flavor of conventional cigarettes mainly relies on a reasonable blend of tobacco leaves, but the flavor of cigarettes can be enriched and corrected by adding aromas, and the flavor of cigarettes can maintain stability. For new tobacco products, especially heated cigarettes and electronic cigarettes, the flavoring effect is more prominent. On the one hand, flavor substances can supplement and improve the natural flavor of the tobacco matrix or the smoking medium. On the other hand, flavor substances have a masking effect on the impurities generated during the aerosol generation process and improve the taste of the aerosol product. In addition, flavor substances can help the aerosol product produce a new and unique style of flavor. Compared with the flavoring process, the release of flavor substances during the use of aerosol generation products is more important, and the stability of the release determines the stability of the aerosol flavor and has an important impact on the quality of the aerosol product.

One end of the aerosol product is detachably disposed within the heating element, and the aerosol generating substrate and the flavor carrier are respectively located within the space or range formed by the first heat source and the second heat source during the operation or use of the aerosol generating product, and are sealed and isolated from the outside through the sealing element, with the side wall through-hole located at the rear end of the sealing element.

[0005] Here, the aerosol generating product that adjusts the release of flavor substances further comprises a housing, the power supply and the control module are located inside the housing, the power supply communicates with the control module, a cavity is provided at one end of the housing, the heating element is located inside the cavity, and the heating element communicates with the control module.

[0006] Optionally, the side wall through-hole communicates with the interior of the aerosol extraction cavity, and the diameter of the side wall through-hole is preferably 0.2 mm to 2 mm.

[0007] The aerosol-generating substrate may optionally be a tobacco substrate, a herb substrate, or a chemically synthesized substrate.
