[0001] This invention relates to the field of electronic atomization technology, and in particular to an aerosol generating product, its preparation method, and an electronic atomization device. Background Technology

[0002] Currently, the mainstream heating technologies in the heated non-combustible product market are resistance heating and electromagnetic heating. These methods primarily rely on heat conduction, convection, and radiation to transfer heat from the outside to the inside. However, a temperature gradient inevitably exists within the aerosol-generating product matrix, leading to uneven heating and localized overheating. Therefore, traditional heating methods suffer from low heating efficiency, high energy consumption, and poor heating uniformity, resulting in incomplete aerosol release and inconsistent performance in the aerosol-generating products, negatively impacting the consumer's inhalation experience.

[0003] Microwaves, as a type of electromagnetic wave, can be used for information transmission and heating. They also have important applications in drying, extraction, and sterilization. For example, industrial products like microwave ovens outperform other conventional heating methods in terms of heating efficiency, energy consumption, and safety. Using microwaves to heat aerosol-generated products offers advantages such as high heating efficiency, low energy consumption, and uniform heating. However, when using microwaves to heat aerosol-generated products, issues remain, including poor heating stability and unpleasant taste when inhaled. Summary of the Invention

[0061] Microwaves at specific frequencies can generate a thermal effect through a heated object. This is mainly because polar molecules in the heated object couple with the microwaves, resulting in displacement polarization and ion polarization, leading to microwave dissipation and the conversion of microwave energy into heat energy, thus raising the temperature of the heated object. The quantification factor is that any heated object possesses a dielectric constant and dielectric loss, and high-dielectric materials can better absorb microwaves and dissipate them to a certain extent to achieve heating. In this embodiment, the addition of the aforementioned dielectric material whose dielectric constant does not change with temperature to the aerosol-generating product slows down the rate of change of the dielectric constant during microwave heating, promoting microwave heating stability and improving the consistency of sensory quality. Furthermore, compared with other dielectric materials, the addition of the aforementioned dielectric material does not affect the inhalation experience of the aerosol-generating product.

[0062] In addition, any one of the components in the above dielectric materials has dielectric properties. Adjusting the proportion of each component can control the dielectric constant of the aerosol-generated product, thereby achieving a more beneficial coupling performance with microwave heating and exhibiting good performance in terms of heating effect and sensory quality.

[0063] The present invention also provides a method for preparing an aerosol-generating article according to one embodiment, comprising the following steps:

[0064] Aerosol-generated products are prepared by mixing dielectric materials and atomizing matrix.
