Description

RELATED APPLICATIONS

[0001] This application claims priority to Chinese patent application No. 202210962760.5, filed on August 11, 2022, entitled "AEROSOL GENERATING PRODUCT, PREPARATION METHOD THEREFOR, AND ELECTRONIC ATOMIZATION APPARATUS", the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

[0002] The present application relates to the field of electronic atomization technologies, and in particular, to an aerosol generating product, a preparation method therefor, and an electronic atomization apparatus.

BACKGROUND

[0003] Currently, in the market of heat-not-burning products, the mainstream heating technologies are resistive heating and electromagnetic heating. These heating methods primarily rely on heat conduction, convection, and radiation to transfer heat from the outside to the inside. There is inevitably a temperature gradient within the matrix of aerosol-generating products, leading to uneven heating of the matrix and thus localized overheating of the matrix. Therefore, conventional heating methods face issues such as low heating efficiency, high energy consumption, and poor heating uniformity, which results in insufficient aerosol release and inconsistent performance of aerosol generating products, affecting the consumer's puffing experience.

[0004] Microwaves, as a form of electromagnetic wave, can be used for both information transmission and heating. Microwaves also have significant applications in drying, extraction, and sterilization. For instance, industrial products like microwave ovens show superior heating efficiency, energy consumption, and safety over other conventional heating methods. Utilizing microwaves for heating the aerosol-generating products offers advantages such as high heating efficiency, low energy consumption, and uniform heating. However, when microwaves are used for heating the aerosol-generating products, challenges remain, including poor stability of microwave heating and unsatisfactory flavor during puffing the aerosol-generating products.

[0065] Microwaves at specific frequencies can generate thermal effects through a heated body, primarily due to the coupling between microwaves and polar molecules within the heated body, which leads to displacement polarization, ion polarization, and microwave dissipation, resulting in the conversion of microwave energy into heat, thereby increasing the temperature of the heated body. A quantitative factor in this process is the dielectric constant and dielectric loss of any heated body. The material with a high dielectric constant is more effective at absorbing microwaves and dissipating microwaves to some extent to achieve the heating effect. In the present embodiments, the aforementioned dielectric material with a dielectric constant that does not change with temperature is added into the aerosol generating product, which slows down the rate of change of the dielectric constant of the aerosol generating product during microwave heating, thereby promoting the stability of microwave heating and improving the consistency of sensory quality before and after puffing. Furthermore, compared to other dielectric materials, the incorporation of the aforementioned dielectric material does not affect the puffing flavor of the aerosol generating product.

[0066] Additionally, each of the components of the aforementioned dielectric material exhibits the dielectric property. By adjusting the ratio of the components, the dielectric constant of the aerosol generating product can be regulated, such that the aerosol generating product exhibits more beneficial coupling performance with microwave heating, better heating efficiency, and sensory quality performances.
