Description

Aerosol generating section and aerosol generating product

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on April 3, 2024, with application number 202410401154.5 and invention name “An aerosol generating segment and aerosol generating product”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of aerosol generation, and in particular to an aerosol generating section and an aerosol generating product. Background Art

[0003] Aerosol-generating products are products that release aerosols. Heated aerosol-generating products utilize an external heat source to heat an aerosol-generating substrate, generating a nicotine-containing aerosol for inhalation. This design is intended to replace traditional aerosol-generating products, such as cigarettes. Compared to traditional cigarettes, which typically burn at temperatures above 800°C, common heated aerosol-generating products typically operate at temperatures below 400°C. This significantly reduces the content of harmful components in the aerosol, thereby minimizing the impact on consumer health and environmental pollution.

[0004] Heated aerosol-generating products need to be used in conjunction with an aerosol-generating device. The aerosol-generating device can directly or indirectly heat the aerosol-generating product to produce an aerosol containing nicotine. Currently, common aerosol-generating devices are equipped with a heating needle (or heating plate), which is inserted into the aerosol-generating product to heat the aerosol-generating substrate. There are two common problems with this heating method. One is that the heating needle (or heating plate) breaks during use; the other is that the aerosol-generating product is prone to adhesion to the heating needle (or heating plate) after being heated.

[0005] Another existing method for heating aerosol-generating products is induction heating. Based on the principle of electromagnetic induction heating, this technology incorporates a susceptor within the aerosol-generating section of the aerosol-generating product. This susceptor is then induction-heated in a dedicated aerosol-generating device. Heat generated by the susceptor is transferred to the aerosol-generating substrate via heat conduction, thereby generating aerosol. Unlike traditional direct heating, this design ensures that the heating element does not directly contact the aerosol-generating substrate, reducing the need for cleaning and preventing damage during use, thereby providing a superior user experience.

[0006] As shown in FIG1 , in aerosol-generating products of the prior art, a receptor 3 is provided in the aerosol-generating substrate 2 of the aerosol-generating section 1, and the receptor 3 is subjected to electromagnetic induction heating by a matching aerosol-generating device. A similar atomization section 4 is usually provided at the end of the aerosol-generating section 1 for sealing. As shown in FIG2 , in some aerosol-generating products of the prior art, an O-shaped filter stick 5 is provided at the end of the aerosol-generating section 1 for sealing. As shown in FIG3 , in some aerosol-generating products of the prior art, a tipping paper 6 is used to seal the end of the aerosol-generating section 1. As shown in FIG4 , in even some aerosol-generating products of the prior art, the end of the aerosol-generating section 1 is completely open and not sealed.

[0007] However, in the above-mentioned aerosol generating products, the susceptors used are all flat sheet structures, and the heating area for aerosol generation is mainly concentrated in the central area of ​​the aerosol generating section 1, resulting in uneven heating and low heating efficiency.

This allows for a wider contact area between the sensor and the aerosol-generating substrate. When the sensor generates heat, the heat is not concentrated entirely in a single area within the aerosol-generating segment, but rather is generated over a wider area within the aerosol-generating segment, improving heating uniformity and efficiency.

[0047] In order to help those skilled in the art better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout the description of this application, "plurality" or "several" means two or more, unless otherwise specifically defined.

[0051] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the efficacy and purpose that can be achieved by this application.

[0052] The present invention provides an aerosol-generating section, comprising an aerosol-generating substrate and a susceptor disposed within the aerosol-generating substrate; wherein the susceptor comprises at least a first susceptor and a second susceptor connected to the first susceptor, wherein the first susceptor and the second susceptor are disposed in an inclined direction relative to each other; or, the susceptor is a twisted susceptor sheet. The susceptors in the aerosol-generating section adopt a multi-segment structure with mutually inclined orientations or a twisted sheet structure. Compared to existing flat sheet structures, the susceptors provided by the present invention have a wider contact area with the aerosol-generating substrate. When the susceptors generate heat, the heat is not completely concentrated in a single area within the aerosol-generating section, but rather is generated over a wider area within the aerosol-generating section, thereby improving heating uniformity and efficiency.

[0053] Referring to Figures 5, 6, 9, and 10, this embodiment provides an aerosol generating section 100, specifically an induction-heated aerosol generating section. The aerosol generating section 100 can be used in conjunction with an external device to generate heat through internally disposed receptors within the aerosol generating section 100, thereby generating aerosol.

[0054] The aerosol-generating section 100 includes an aerosol-generating substrate 10 and a susceptor 20 disposed within the aerosol-generating substrate 10. The aerosol-generating substrate 10 is a substrate that, when heated, produces an inhalable aerosol. The susceptor 20 is an object that converts electromagnetic energy into heat in an alternating magnetic field. The susceptor 20 can be manufactured from one or more materials. The susceptor 20 can be made of any metal material that can be heated to a temperature sufficient to generate an aerosol by induction heating, such as aluminum alloy, ferrite, stainless steel, or Permalloy.

[0055] Specifically, the heating mechanism of the susceptor 20 can be achieved by applying high-frequency alternating current to an induction coil, generating an alternating magnetic field. Under the influence of the alternating magnetic field, eddy currents are generated in the susceptor placed in the alternating magnetic field, increasing the resistance of the susceptor 20 and significantly increasing its internal heat. Alternatively, the heating mechanism of the susceptor 20 can be achieved by repeatedly magnetizing and demagnetizing the iron crystals in the susceptor 20 material by the alternating magnetic field, causing rapid magnetic domain flipping, resulting in hysteresis loss, and thus generating more heat. The susceptor 20 can be made of the desired material according to actual use requirements. It only needs to be controlled by an external device to generate heat in the susceptor 20, thereby generating aerosol in the aerosol generating section 100.

[0056] The sensor 20 includes at least a first sensor 21 and a second sensor 22 connected to the first sensor 21. The first sensor 21 and the second sensor 22 are arranged in an oblique direction relative to each other. In other words, the sensor 20 is composed of at least two units arranged in different directions, rather than a single flat sheet-like structure. Therefore, when the sensor 20 generates heat, the heating area of ​​the sensor 20 is not a straight line with a certain thickness, but rather a non-linear cross-section. This allows the sensor 20 to generate heat over a wider area within the aerosol-generating substrate 10, allowing the sensor 20 to heat all sides of the aerosol-generating substrate 10 more evenly and improving the heating efficiency of the aerosol-generating substrate 10.

[0057] It should be noted that the inclination between the first susceptor 21 and the second susceptor 22 can be transversely inclined and / or longitudinally inclined. For example, in the cross-sectional view of the aerosol generating section shown in FIG5 , the first susceptor 21 and the second susceptor 22 are arranged transversely inclined relative to each other, with the angle between them not being 0° or 180°, and the first susceptor 21 and the second susceptor 22 are arranged to extend axially of the aerosol generating section 100. Alternatively, in the longitudinal cross-sectional view of the aerosol generating article shown in FIG9 , the first susceptor 21 and the second susceptor 22 are arranged longitudinally inclined relative to each other, with the angle between them not being 0° or 180°, and the first susceptor 21 and the second susceptor 22 are arranged to extend radially (or parallel to the radial direction) of the aerosol generating section 100.

[0058] Furthermore, it should be noted that the first and second susceptors 21, 22 may also extend at an angle. For example, when the first and second susceptors 21, 22 extend toward the axial direction of the aerosol-generating segment 100, the first and second susceptors 21, 22 may extend at an angle along the axial direction. That is, one of the two axial ends of the first and second susceptors 21, 22 may be closer to the central axis of the aerosol-generating segment 100 than the other, and the extension direction of the first and second susceptors 21, 22 may not be completely parallel to the axial direction of the aerosol-generating segment 100. Similarly, when the first and second susceptors 21, 22 extend toward (or parallel to) the radial direction of the aerosol-generating segment 100, the extension direction of the first and second susceptors 21, 22 may not be completely parallel to the radial direction of the aerosol-generating segment 100.

[0059] Alternatively, as shown in FIG10 , the susceptor 20 may be a twisted susceptor sheet. A twisted susceptor sheet refers to a sheet-like structure in which the two ends of the susceptor 20 are twisted relative to each other to a certain degree, and the surface connecting the two ends of the susceptor 20 is a curved surface rather than a flat surface. In other words, the susceptor 20 is not a flat sheet structure. This means that when the susceptor 20 senses heat, the heating area of ​​the susceptor 20 is not located in a single linear region, but rather has a certain range. This allows the susceptor 20 to heat a wider area within the aerosol-generating substrate 10, allowing the susceptor 20 to heat the various sides of the aerosol-generating substrate 10 more evenly and improving the heating efficiency of the susceptor 20 on the aerosol-generating substrate 10.

[0060] That is to say, the specific structural shape of the sensor 20 is a structure having at least two mutually inclined units or a twisted sheet structure, that is, the sensor 20 is a pleated sensor, which can increase the contact range between the sensor 22 and the aerosol generating substrate 10, thereby improving the uniformity of heating and improving the heating efficiency.

[0061] Compared to the prior art, the aerosol generating section 100 provided in this embodiment has a heating area of ​​the sensor 20 that is no longer concentrated in the central area during induction heating, but can extend to a wider area of ​​the aerosol generating substrate 10. This can improve the heating uniformity of the aerosol generating substrate 10 by the sensor 20 and also improve the heating efficiency.

[0062] Preferably, in one embodiment, the aerosol generating material in the aerosol generating substrate 10 is randomly filled. That is, the material for generating aerosol in the aerosol generating substrate 10 is randomly filled, rather than uniformly arranged in a certain order. Herein, disordered filling means that the aerosol generating material is arranged in the aerosol generating section 100 in an irregular form. For example, when the material for generating aerosol in the aerosol generating substrate 10 is tobacco, the arrangement of each tobacco is disorderly and disorderly, rather than arranging the tobacco in sequence. The aerosol generating substrate 10 is manufactured using a molding process similar to that of traditional cigarettes, rather than an orderly filling process similar to that of paper filter rods.

[0063] Preferably, in one embodiment, the aerosol-generating material is one or more of atomized shredded tobacco, expanded shredded tobacco, reconstituted tobacco leaf shreds, and reconstituted tobacco leaf flakes. That is, the aerosol-generating material can be in the form of a single material structure or a mixture of multiple material structures.

[0064] Preferably, in one embodiment, the aerosol-generating material is a plant material, and the plant material includes a tobacco material and / or a non-tobacco material. The non-tobacco material may be a herbaceous plant material other than tobacco.

[0065] Preferably, in one embodiment, when the aerosol generating material includes the tobacco material, the tobacco material includes one or more of tobacco leaves, tobacco stems, tobacco powder, homogenized tobacco and expanded tobacco.

[0066] Preferably, in one embodiment, the aerosol-generating substrate 10 includes nicotine salt, wherein the nicotine salt can be formed by adding a suitable acid including an organic acid or an inorganic acid to nicotine.

[0067] Preferably, in one embodiment, the sensor 20 includes a first sensor 21 and a second sensor 22. That is, in this embodiment, the sensor 20 adopts a structure in which at least two units are arranged obliquely relative to each other, rather than a twisted sheet-like structure. The first sensor 21 and the second sensor 22 are arranged sequentially along the radial direction of the aerosol generating section 100. For example, in the embodiment shown in FIG5 , the sensor 20 is composed of only one first sensor 21 and one second sensor 22. The cross-section of the sensor 20 is generally V-shaped. This structure allows the sensor 20 to generate heat not only in the central area of ​​the aerosol generating section 100 during induction heating, but also in a larger area near the central area. Of course, in other embodiments, the sensor 20 may also be composed of a larger number of first sensors 21 and a larger number of second sensors 22.

[0068] Preferably, in one embodiment, a plurality of (at least two) first receptacles 21 are provided, and the plurality of first receptacles 21 are sequentially spaced apart along the radial direction of the aerosol generating section 100, and a second receptacle 22 is connected between two adjacent first receptacles 21. That is, in this embodiment, the receptacle 20 is composed of a plurality of first receptacles 21 and second receptacles 22 connected end to end in sequence, wherein the plurality of first receptacles 21 and second receptacles 22 connected end to end in sequence means that the tail of the previous first receptacle 21 is connected to the head of the second receptacle 22, and the tail of the second receptacle 22 is connected to the head of the next first receptacle 21. For example, in the embodiment shown in FIG6, the receptacle 20 is composed of two first receptacles 21 and two second receptacles 22, and the cross-section of the receptacle 20 presents an overall "W"-shaped structure. The receptacles 20 can be arranged vertically, as shown in FIG7; or the receptacles 20 can be arranged horizontally, as shown in FIG8. Of course, in other embodiments, the sensor 20 may also be composed of two first sensor 21 and one second sensor 22, so that the cross-section presents a "Z"-shaped structure. In other embodiments, the sensor 20 may also be composed of a larger number of first sensor 21 and second sensor 22.

[0069] Preferably, in one embodiment, the susceptor 20 includes a first susceptor 21 and a second susceptor 22. That is, in this embodiment, the susceptor 20 is a structure of at least two units arranged obliquely relative to each other, rather than a twisted sheet-like structure. The first susceptor 21 and the second susceptor 22 are sequentially arranged along the axial direction of the aerosol generating section 100.

[0070] Preferably, in one embodiment, a plurality (at least two) of the first receptacles 21 are provided. The plurality of first receptacles 21 are sequentially spaced apart along the axial direction of the aerosol generating section 100, and a second receptacle 22 is connected between two adjacent first receptacles 21. That is, in this embodiment, the receptacle 20 is composed of a plurality of first receptacles 21 and second receptacles 22 connected end to end. The phrase "a plurality of first receptacles 21 and second receptacles 22 connected end to end" means that the tail of the preceding first receptacle 21 is connected to the head of the second receptacle 22, and the tail of the second receptacle 22 is connected to the head of the following first receptacle 21. For example, in the embodiment shown in FIG9 , the receptacle 20 is composed of a plurality of first receptacles 21 and a plurality of second receptacles 22, and the cross-section of the receptacle 20 exhibits an overall wavy structure. Similarly, the number of first receptacles 21 and second receptacles 22 included in the receptacle 20 can also be selected.

[0071] Preferably, in one embodiment, both the first susceptor 21 and the second susceptor 22 are flat sheet structures. That is, the susceptor 20 is composed of a plurality of flat sheet units connected together, and adjacent units are tilted relative to each other, rather than parallel, thereby improving heating uniformity and efficiency.

[0072] Preferably, in one embodiment, the angle between the first susceptor 21 and the second susceptor 22 is 30-135°. More preferably, in one embodiment, the angle between the first susceptor 21 and the second susceptor 22 is 60-90°. This can further improve heating uniformity and heating efficiency.

[0073] Preferably, in one embodiment, the susceptor 20 is a twisted susceptor sheet. That is, in this embodiment, the susceptor 20 is a twisted sheet structure, rather than a structure in which at least two units are arranged at an angle relative to each other. The susceptor 20 is twisted along the axial direction of the aerosol-generating segment 100. That is, the susceptor 20 is arranged along the axial direction of the aerosol-generating segment 100, and the susceptor 20 is twisted to a certain extent at both ends of the axial direction of the aerosol-generating segment 100. Specifically, the susceptor 20 is arranged at the center of the aerosol-generating substrate 10. Of course, in other embodiments, the susceptor 20 can also be twisted along other directions of the aerosol-generating segment 100, such as radially, as long as the twisted susceptor 20 can prevent the heating areas on each side from being concentrated in a single area when heating. By twisting the susceptor 20 along the axial direction of the aerosol-generating segment 100, the heating uniformity and heating efficiency can be further improved.

[0074] Preferably, in one embodiment, the twist angle of the susceptor sheet in the aerosol generating section 100 is 15°-20° per millimeter. For example, in the aerosol generating section 100 of 12 mm, the twist angle of the susceptor sheet is 180°-360°.

[0075] Preferably, in one embodiment, it further comprises a wrapping body 30, which wraps around the outer periphery of the aerosol generating substrate 10. Specifically, the wrapping body 30 can be made of paper.

[0076] Preferably, in one embodiment, the ratio of the projected width of the susceptor 20 to the diameter of the aerosol-generating segment 100 is 0.4-0.75. That is, the ratio of the width of the orthographic projection of the susceptor 20 onto a cross section of the aerosol-generating segment 100 to the diameter of the aerosol-generating segment 100 on that cross section is between 0.4-0.75. For example, in one embodiment, if the projected width of the susceptor 20 is 3 and the diameter of the aerosol-generating segment 100 is 7, the ratio is 3 / 7 = 0.43; if the projected width of the susceptor 20 is 4 and the diameter of the aerosol-generating segment 100 is 7, the ratio is 4 / 7 = 0.57; and if the projected width of the susceptor 20 is 5 and the diameter of the aerosol-generating segment 100 is 7, the ratio is 5 / 7 = 0.71. This structure can further improve heating uniformity and efficiency. The projected width of the susceptor 20 refers to the distance between two outermost points of the susceptor 20 on a cross section of the aerosol generating section 100 .

[0077] Preferably, in one embodiment, the susceptor 20 is a twisted susceptor sheet. That is, in this embodiment, the susceptor 20 is a twisted sheet structure rather than a structure in which at least two units are arranged obliquely relative to each other. The ratio of the width of the susceptor sheet (untwisted) to the diameter of the aerosol generating section 100 is 0.4-0.75.

[0078] Preferably, in one embodiment, the projection width of the sensor 20 is 4-7 mm.

[0079] Preferably, in one embodiment, the diameter of the aerosol generating section 100 is 5-8 mm.

[0080] Preferably, in one embodiment, the thickness of the susceptor 20 is 20-100 μm. More preferably, in one embodiment, the thickness of the susceptor 20 is 40-65 μm. The thickness of the susceptor 20 refers to the distance between the inner and outer surfaces of the susceptor 20 in a cross-section of the aerosol generating section 100. This structure minimizes the space occupied by the susceptor 20 and affects the arrangement of materials in the aerosol generating substrate 10, while ensuring the heating effect as much as possible.

[0081] Please refer to FIG. 9 and FIG. 11 . In one embodiment, an aerosol generating article 1000 is provided, which includes the aerosol generating section 100 , the hollow section 200 and the filtering section 300 connected in sequence.

[0082] The above description is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present invention, but these improvements all fall within the scope of protection of the present invention.
