[0044] This application provides an aerosol-generating article 10, such as... Figure 1-3 As shown, it includes a tobacco segment 1 and a mouthpiece segment 2. The tobacco segment 1 includes a first receptor 11 and a second receptor 12, which are disposed within the tobacco segment 1 and distributed along the axial direction of the aerosol generating article 10. The first receptor 11 is located at one end near the mouthpiece segment 2.

[0045] The aerosol generating article of this application has two receptors, which improves the heating efficiency of the receptors inside the aerosol generating article 10 and increases the amount of smoke generated by the aerosol generating article 10.

[0046] In one embodiment of this application, the mouthpiece segment 2 includes a mouthpiece and a connecting segment. The connecting segment is located between the mouthpiece and the tobacco segment and is used to guide the aerosol to the mouthpiece. The mouthpiece can be held in the mouth of a user, and the user can inhale the aerosol by sucking on the mouthpiece. The tobacco segment includes a tobacco layer, a first receptor 11, a second receptor 12, and a paper layer.

[0047] In one embodiment of this application, the tobacco segment of the aerosol-generating article may include an aerosol-generating matrix. As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form an inhalable aerosol. The aerosol-generating matrix may include tobacco-containing material containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, the aerosol-generating matrix may be a tobacco-containing aerosol-generating matrix or an aerosol-generating matrix containing solid tobacco. Alternatively, the aerosol-generating matrix may include non-tobacco materials. The aerosol-generating matrix may also include an aerosol-forming agent. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.

[0048] As needed, the aerosol generating matrix may contain additional tobacco or non-tobacco volatile aroma compounds released when the aerosol generating matrix is ​​heated. The aerosol generating matrix may also contain microcapsules, which may contain additional tobacco or non-tobacco volatile aroma compounds, and such microcapsules may melt during heating of the solid aerosol generating matrix.

[0049] In one embodiment of this application, an electromagnetic coil is disposed within the aerosol generating apparatus 20, and a first sensor 11 and a second sensor 12 are disposed within the aerosol generating article 10. A power supply device within the aerosol generating apparatus 20 applies alternating current to the electromagnetic coil to generate a changing magnetic field within the space containing the first sensor 11 and the second sensor 12. When the first sensor 11 and the second sensor 12 are in the changing magnetic field, according to the law of electromagnetic induction, the magnetic flux passing through the first sensor 11 and the second sensor 12 changes, generating an induced electromotive force within the first sensor 11 and the second sensor 12. Since the first sensor 11 is a conductor with relatively low resistance, a closed loop is formed within the first sensor 11 under the influence of the induced electromotive force, generating induced eddy currents; similarly, a closed loop is formed within the second sensor 12, generating induced eddy currents. When the eddy current flows inside the first sensor 11 and the second sensor 12, electrical energy is converted into heat energy due to the resistance of the first sensor 11 and the second sensor 12, thereby raising the temperature of the first sensor 11 and the second sensor 12. The heat generated by the first sensor 11 and the second sensor 12 can heat the aerosol generating product 10.

[0050] In one embodiment of this application, the temperature information at the locations of the first sensor 11 and the second sensor 12 is crucial for the temperature control of the aerosol generating device 20. Based on the heating principle of electromagnetic heating, it is known that the heat generated by the first sensor 11 and the second sensor 12 corresponds to the electrical parameters (such as inductance, resistance, or current) at the electromagnetic coil. Thus, the heat generated by the first sensor 11 and the second sensor 12 can be deduced from the electrical parameters of the electromagnetic coil, which in turn allows the deduction of the temperatures of the first sensor 11 and the second sensor 12.

[0051] It should be noted that when the temperature of the first receptor 11 and the second receptor 12 is below the Curie temperature, they typically exhibit ferromagnetism or ferrimagnetism, with internal magnetic domains and spontaneously arranged magnetic moments, resulting in strong magnetism. When the temperature rises above the Curie temperature, the first receptor 11 and the second receptor 12 become paramagnetic. At this point, the magnetic domains disintegrate, the arrangement of magnetic moments becomes chaotic and disordered, the average magnetic moment becomes zero, the magnetism of the material disappears, and its magnetic field easily changes with changes in the surrounding magnetic field.

[0052] In one embodiment of this application, the Curie temperature of the first receptor 11 and the second receptor 12 is determined by the material of the first receptor 11 and the second receptor 12 themselves. The first Curie temperature of the first receptor 11 and the second Curie temperature of the second receptor 12 can be obtained by the material of the first receptor 11 and the second receptor 12.

[0053] In one embodiment of this application, the first receptor 11 has a first Curie temperature below 450°C, and the second receptor 12 has a second Curie temperature above 600°C. This allows one of the first receptor 11 or the second receptor 12 to have a heating function within the heating temperature range of the aerosol generating article 10, while the other has a temperature detection function. Furthermore, when the temperature rises to a certain level, the first receptor 11 and the second receptor 12 lose their magnetism and stop heating, thereby preventing the aerosol generating article 10 from scorching.

[0054] In one embodiment of this application, the first sensor 11 is a high-nickel alloy. The Curie temperature of the high-nickel alloy is below 450°C, ensuring a good correlation between the electrical parameters of the first sensor 11 and the temperature within the heat preservation range of the aerosol generating article 10. The temperature of the aerosol generating article 10 can be determined based on the electrical parameters of the first sensor 11, thereby controlling the temperature of the aerosol generating article 10 by controlling its electrical parameters. In one embodiment of this application, the nickel mass fraction in the high-nickel alloy is greater than or equal to 75%, such as 1J85 or 1J79.

[0055] In one embodiment of this application, the second magnet 12 is a soft magnetic alloy with a distance temperature higher than 600°C. This ensures that the second magnet 12 possesses strong magnetism within the heat preservation range of the aerosol-generating product 10, allowing it to heat the aerosol-generating product 10 under the influence of an electromagnetic field. In one embodiment of this application, the iron mass fraction in the ferromagnetic alloy is greater than or equal to 78%. In one embodiment of this application, the second magnet 12 is pure iron, and an anti-corrosion protective layer can be formed on the surface of the pure iron. This anti-corrosion protective layer can be a nickel layer formed by electroplating.

[0056] In one embodiment of this application, the tobacco segment 1 includes a first tobacco segment 13 and a second tobacco segment 14. A first receptor 11 is disposed within the first tobacco segment 13, and a second receptor 12 is disposed within the second tobacco segment 14. In one embodiment of this application, the morphology of the tobacco in the first tobacco segment 13 is different from that in the second tobacco segment 14. During design, first receptors 11 and second receptors 12 with different characteristics can be selected based on the morphology of the first tobacco segment 13 and the second tobacco segment 14. In one embodiment of this application, the morphology of the tobacco includes ordered tobacco and disordered tobacco. In one embodiment of this application, the tobacco includes particulate tobacco, sheet tobacco, disordered tobacco shreds, and tobacco paste, etc.

[0057] In one embodiment of this application, the first tobacco segment 13 comprises tobacco particles. In one embodiment of this application, the second tobacco segment 14 comprises 20%-80% tobacco particles and 20%-80% disordered tobacco shreds and sheet-like tobacco shreds.
