Description

Technical Field

[0001] The present application relates to the technical field of atomizers, and in particular to an atomizer host and an aerosol generating device. Background Art

[0002] At present, the heat-not-burn (HNB) products on the market are usually in the form of long cylindrical strips. The heating element is independent of the aerosol-generating matrix. When used, the user inserts the heating element into the aerosol-generating matrix or wraps it around the outside of the aerosol-generating matrix. The heating element and the aerosol-generating matrix are in direct contact. Energy is applied to the heating element to make it heat up and then bake the aerosol-generating matrix to produce aerosol for the user to inhale.

[0003] Due to the shape of the traditional heat-not-burn aerosol generating matrix, the aerosol generating matrix is ​​in direct contact with the heating element, and the local aerosol generating matrix is ​​always heated by the heating element for a long time. The aerosol generating matrix is ​​repeatedly heated for a long time, which is prone to produce a burnt smell, affecting the consistency of taste, and thus affecting the user experience.

[0011] The difference between the second preset time length and the first preset time length is 5 seconds to 15 seconds.

[0012] Among them, when the controller detects that the heating process of the heating element is interrupted and the total working time of the interrupted heating element reaches a third preset time, the next heating element is controlled to start working, and the third preset time is shorter than the second preset time.

[0013] The difference between the third preset time length and the second preset time length is 1 second to 5 seconds.

[0014] Wherein, the first preset time period includes: a first time period, a second time period and a third time period.

[0017] Wherein, the first temperature is 20-30°C, the second temperature is 300-350°C, and the third temperature is 220-280°C.

The aerosol-generating article 1 is disposed at one end of the atomizing main unit 3 near the gas connection assembly 2; that is, the aerosol-generating article 1 is disposed between the gas connection assembly 2 and the atomizing main unit 3, and the aerosol-generating article 1 contacts the heating element 31.

[0056] See also Figure 2 , Figure 2 It is a structural schematic diagram of the first embodiment of the aerosol generating product provided by this application.

[0057] The aerosol-generating article 1 includes an aerosol-generating substrate 11 and an encapsulation layer 12. The encapsulation layer 12 covers at least a portion of the aerosol-generating substrate 11, separating the aerosol-generating substrate 11 from the heating element 31. The aerosol-generating article 1 is replaceable and can be used as a disposable item. The area of ​​the aerosol-generating substrate 11 covered by the encapsulation layer 12 is selected based on the specific implementation; it is sufficient that the encapsulation layer 12 separates the aerosol-generating substrate 11 from the heating element 31; that is, the area of ​​the aerosol-generating substrate 11 covered by the encapsulation layer 12 is sufficient to prevent direct contact between the aerosol-generating substrate 11 and the heating element 31.

[0058] The heating element 31 is used to heat the encapsulation layer 12, which transfers heat to the aerosol-generating substrate 11 within the aerosol-generating article 1 to form an aerosol. This is known as resistive heating of the aerosol-generating article 1. Alternatively, the heating element 31 is an electromagnetic element, such as an electromagnetic coil, and the encapsulation layer 12 generates eddy currents and heats the aerosol-generating substrate 11 in the electromagnetic element's magnetic field, thereby heating the aerosol-generating substrate 11 to form an aerosol. This is known as electromagnetic heating of the aerosol-generating article 1. When electromagnetic heating of the aerosol-generating article 1 is used, the encapsulation layer 12 serves as the heating layer. The heating layer generates eddy currents and self-heats in the magnetic field of the heating element 31 (electromagnetic element), thereby heating the aerosol-generating substrate 11 to form an aerosol.

[0059] When resistively heating the aerosol-generating article 1, the encapsulation layer 12 has uniform thermal conductivity and can be made of glass, ceramic, metal, or other materials to meet the requirements; that is, the encapsulation layer 12 can be a metal layer, a ceramic layer, or a glass layer. It will be appreciated that the uniform thermal conductivity of the encapsulation layer 12 enables uniform heating of the aerosol-generating substrate 11, which helps improve the consistency of aerosol quality, namely, the consistency of taste. When electromagnetically heating the aerosol-generating article 1, the encapsulation layer 12 is made of a metal that can heat in a magnetic field, such as aluminum foil.

[0060] By configuring the aerosol-generating article 1 to include an aerosol-generating substrate 11 and an encapsulation layer 12, with the encapsulation layer 12 covering at least a portion of the aerosol-generating substrate 11, the encapsulation layer 12 separates the aerosol-generating substrate 11 from the heating element 31, preventing direct contact between the heating element 31 and the aerosol-generating substrate 11. This also prevents aerosol residue from adhering to the heating element 31 when the heating element 31 heats the aerosol-generating substrate 11 to generate aerosol, thereby avoiding the problem of aerosol residue adhering to the heating element 31 and being difficult to clean. Even if the heating element 31 is reused, the taste of the aerosol is not affected, thereby improving the user experience. Furthermore, since the encapsulation layer 12 covers at least a portion of the aerosol-generating substrate 11, after the aerosol-generating substrate 11 is consumed, the encapsulation layer 12 and the aerosol-generating substrate 11 are discarded together, and a new aerosol-generating article 1 is used, making replacement of the aerosol-generating substrate 11 more convenient, faster, and cleaner.

[0061] In a specific implementation, the aerosol-generating matrix 11 can be in the form of a powder, filaments, or aggregated to form a block. The aerosol-generating matrix 11 is in the form of a powder or filament. Since powders or filaments cannot be shaped, a mold is required. The encapsulation layer 12 is laid in the mold and filled with the aerosol-generating matrix 11 to obtain an aerosol-generating product 1 of a predetermined shape. The aerosol-generating matrix 11 is in the form of a block, which makes it easier to assemble the aerosol-generating matrix 11 and the encapsulation layer 12 to form the aerosol-generating product 1. The aerosol-generating matrix 11 can be designed into a columnar, layered, or other shape as needed to obtain the desired shape of the aerosol-generating product 1. In the following description, the aerosol-generating matrix 11 is described as a block.

[0062] It is understandable that the encapsulation layer 12 covering the aerosol generating substrate 11 is at least partially used to separate the aerosol generating substrate 11 from the heating element 31 . To ensure higher heating efficiency, this portion of the encapsulation layer 12 is bonded to the aerosol generating substrate 11 .

[0063] In the first embodiment of the aerosol-generating article 1, the aerosol-generating substrate 11 is aggregated to form a columnar structure, and the encapsulation layer 12 is configured as a hollow columnar structure that covers the sides of the aerosol-generating substrate 11. For example, the encapsulation layer 12 can be in the form of a sheet, which is wound around to form the hollow columnar structure; or the encapsulation layer 12 can be in the form of a ribbon, which is spirally wound to form the hollow columnar structure. The aerosol-generating article 1 in this embodiment can utilize either resistive heating or electromagnetic heating, depending on the specific needs. It should be understood that in this embodiment, the sides of the aerosol-generating substrate 11 serve as the heating surface, while the bottom serves as the aerosol release surface.

[0064] For example, the columnar body formed by the aggregation of the aerosol-generating substrate 11 can be a cylinder, a triangular prism, a quadrangular prism, etc. The structural dimensions of the encapsulation layer 12 are configured to match the structural dimensions of the aerosol-generating substrate 11. It is sufficient that the encapsulation layer 12 completely covers the side surfaces of the aerosol-generating substrate 11. To ensure high heating efficiency, the encapsulation layer 12 is disposed in close contact with the side surfaces of the aerosol-generating substrate 11.

[0065] When electromagnetic heating is used to generate the aerosol product 1, the heating element 31 is an electromagnetic component, and the encapsulation layer 12 is a heating layer. The heating layer generates eddy currents in the magnetic field of the electromagnetic component and generates heat to heat the aerosol generating matrix 11 to form an aerosol. The heating layer is arranged in a columnar structure and forms a non-closed loop, and the aerosol generating matrix 11 is arranged in the columnar structure. Specifically, the heating layer is curled and arranged to form a receiving space, and the receiving space is used to receive the aerosol generating matrix 11. The heating layer has a first end and a second end opposite to the first end, and the first end is arranged opposite to the second end. The surface of the heating layer that contacts the aerosol generating matrix 11 is the inner wall surface of the receiving space, and the surface of the heating layer that is not in contact with the aerosol generating matrix 11 is the outer wall surface of the receiving space. The first end and the second end of the heating layer are both spaced apart from the inner wall surface and the outer wall surface of the receiving space.

[0066] In one embodiment, the aerosol generating substrate 11 is aggregated to form a columnar body, and the heating layer is arranged around the side of the aerosol generating substrate 11 to form a hollow tubular body, and a notch is provided on the side wall of the hollow tubular body, so that the heating layer forms a non-closed loop. In other words, the first end and the second end of the heating layer are arranged opposite to each other and spaced apart. The opposite ends of the hollow tubular body are both open ends, and the heating layer covers the side of the aerosol generating substrate 11. The structure is as follows: Figure 2 wherein the notch extends from one end of the hollow tubular body to the other end along the axial direction of the hollow tubular body.

[0067] In another embodiment, the heating layer is in the shape of a rectangular sheet, and the heating layer is curled around one side to form a hollow column, and there is a gap between the two opposite sides of the heating layer so that the heating layer forms a non-closed loop, the structure is as follows Figure 2 As shown. It is understood that the cross-sectional shape of the aerosol generating substrate 11 can be circular, triangular, or the like. When the cross-sectional shape of the aerosol generating substrate 11 is circular, the diameter of the aerosol generating substrate 11 is 3.0 mm to 20 mm. The heating layer is aluminum foil or copper foil, and the thickness of the heating layer is 0.05 mm to 0.3 mm.

[0068] When resistive heating aerosol generating article 1 is used, Figure 2 The encapsulation layer 12 in the structure can form a closed loop or a non-closed loop, and the specific design is based on the needs.

[0069] See also Figure 3, Figure 3 It is a structural schematic diagram of the second embodiment of the aerosol generating product provided by this application.

[0070] In a second embodiment of the aerosol-generating article 1, the aerosol-generating substrate 11 is assembled into a columnar shape; illustratively, the aerosol-generating substrate 11 may be a cylinder, a triangular prism, a quadrangular prism, or the like. An insertion groove 111 is provided on the aerosol-generating substrate 11. The encapsulation layer 12 is disposed within the insertion groove 111 and covers the inner wall of the insertion groove 111. The heating element 31 is inserted into the cavity 120 formed by the encapsulation layer 12. The aerosol-generating article 1 in this embodiment utilizes resistive heating. It will be appreciated that the inner wall of the insertion groove 111 of the aerosol-generating substrate 11 in this embodiment serves as the heating surface, while the outer surface of the aerosol-generating substrate 11 may serve as the aerosol release surface, with the specific design being determined as needed. In one embodiment, the encapsulation layer 12 may be folded into a multi-layer structure and then inserted into the aerosol-generating substrate 11. During use, the sheet-like heating element 31 is inserted between the layers of the encapsulation layer 12 to prevent contact between the heating element 31 and the aerosol-generating substrate 11.

[0071] See also Figure 4 , Figure 4 It is a structural schematic diagram of the third embodiment of the aerosol generating product provided by this application.

[0072] In a third embodiment of the aerosol-generating article 1, an aerosol-generating substrate 11 is assembled to form a laminate. An encapsulation layer 12 is stacked and arranged with the aerosol-generating substrate 11 and rolled together into a columnar or column-like shape, such as a spring roll. This ensures that the outer surface of the aerosol-generating substrate 11 is wrapped by the encapsulation layer 12, and the interior of the aerosol-generating substrate 11 is also provided with the encapsulation layer 12. Specifically, the encapsulation layer 12 has a first end and a second end, the second end being rolled around the first end to form a roll, and the aerosol-generating substrate 11 is filled in the gaps between the rolled encapsulation layer 12. For example, the cross-section of the aerosol-generating substrate 11 laminate can be square, rectangular, or the like, and the columnar shape formed by the aerosol-generating substrate 11 and the encapsulation layer 12 being rolled together can be cylindrical, triangular, or quadrangular. The aerosol-generating article 1 in this embodiment can utilize either resistive or electromagnetic heating, depending on the specific needs.

[0073] It will be appreciated that in this embodiment, the cylindrical side surfaces formed by the curling of the aerosol-generating substrate 11 and the encapsulation layer 12 serve as the heating surface, while the bottom surface serves as the aerosol-releasing surface. The structural dimensions of the encapsulation layer 12 are coordinated with those of the layered aerosol-generating substrate 11, allowing the encapsulation layer 12 to curl together with the aerosol-generating substrate 11 and ensuring that the encapsulation layer 12 separates the aerosol-generating substrate 11 from the heating element 31.

[0074] When electromagnetic heating is used to generate the aerosol product 1, the heating element 31 is an electromagnetic component, and the encapsulation layer 12 is a heating layer. The heating layer generates eddy currents in the magnetic field of the electromagnetic component and generates heat to heat the aerosol generating matrix 11 to form an aerosol. The heating layer is arranged in a columnar structure and forms a non-closed loop, and the aerosol generating matrix 11 is arranged in the columnar structure. Specifically, the aerosol generating matrix 11 is gathered to form a columnar body, and the heating layer is a rectangular sheet. One side of the heating layer is located on the side of the aerosol generating matrix 11, and the heating layer is curled. The other side of the heating layer is located inside the aerosol generating matrix 11 to form a non-closed loop (such as Figure 4 As shown). That is, the aerosol-generating substrate 11 is covered on the heating layer, the second end of the heating layer is coiled around the first end, the first end of the heating layer is curled and located inside the aerosol-generating substrate 11, and the second end of the heating layer is located outside the aerosol-generating substrate 11. The inner wall surface of the receiving space is the first surface 127 of the heating layer and the portion of the second surface 128 of the heating layer that is curled into the aerosol-generating substrate 11; the outer wall surface of the receiving space is the portion of the second surface 128 of the heating layer that is not curled into the aerosol-generating substrate 11 and is not in contact with the aerosol-generating substrate 11. The first end of the heating layer is spaced apart from the inner wall surface of the receiving space, and the second end of the heating layer is spaced apart from the outer wall surface of the receiving space.

[0075] See also Figure 5 , Figure 5 It is a structural schematic diagram of the fourth embodiment of the aerosol generating product provided by the present application.

[0076] In a fourth embodiment of the aerosol-generating article 1, the aerosol-generating substrate 11 is aggregated to form a layered structure, and the encapsulation layer 12 covers the entire outer surface of the aerosol-generating substrate 11. Furthermore, a first through-hole 121 is provided in the encapsulation layer 12 on the side of the aerosol-generating substrate 11 away from the heating element 31 to release the aerosol. The aerosol-generating article 1 in this embodiment can utilize either resistive heating or electromagnetic heating, depending on the specific needs.

[0077] For example, the cross-section of the aerosol-generating substrate 11 layer can be circular, square, rectangular, or the like, depending on the specific design. It will be appreciated that in this embodiment, since the encapsulation layer 12 covers the entire outer surface of the aerosol-generating substrate 11, the surfaces of the aerosol-generating substrate 11 in contact with the encapsulation layer 12 are both heating surfaces, and the surface of the aerosol-generating substrate 11 corresponding to the first through-holes 121 in the encapsulation layer 12 serves as the aerosol-releasing surface.

[0078] See also Figure 6 and Figure 7 , Figure 6 is a schematic structural diagram of the fifth embodiment of the aerosol generating article provided by the present application, Figure 7This is another structural schematic diagram of the fifth embodiment of the aerosol generating article provided by the present application.

[0079] In the fifth embodiment of the aerosol-generating article 1, the aerosol-generating matrix 11 is aggregated to form a layered structure. For example, the cross-section of the aerosol-generating matrix 11 layered structure can be circular, square, rectangular, or the like, depending on the specific design. The encapsulation layer 12 covers the surface of the aerosol-generating matrix 11 on the side closest to the heating element 31, thereby separating the aerosol-generating matrix 11 from the heating element 31. Specifically, the encapsulation layer 12 encloses a recess 122, in which the aerosol-generating matrix 11 is disposed. The recess 122 includes an annular sidewall and a bottom wall, with a lug 1221 formed on the outer side of the annular sidewall to facilitate attachment of the aerosol-generating article 1 to the atomizer 3.

[0080] It will be understood that in this embodiment, the surface of the aerosol-generating substrate 11 in contact with the encapsulation layer 12 serves as the heating surface, and any surface of the aerosol-generating substrate 11 other than that in contact with the encapsulation layer 12 can serve as the aerosol-releasing surface, depending on specific needs. Specifically, the bottom surface of the aerosol-generating substrate 11 may mate with the bottom wall of the recess 122, and the side surfaces of the aerosol-generating substrate 11 may or may not contact the annular sidewall of the recess 122, depending on specific needs. The aerosol-generating article 1 in this embodiment can utilize either resistive heating or electromagnetic heating, depending on specific needs.

[0081] In one embodiment, the plurality of aerosol-generating articles 1 are independent of each other; the packaging layers 12 of the plurality of aerosol-generating articles 1 are independent of each other, such as Figure 6 As shown. Specifically, each packaging layer 12 is surrounded by a recess 122, and multiple packaging layers 12 are surrounded by multiple recesses 122. An aerosol generating matrix 11 is provided in each recess 122, and adjacent recesses 122 are spaced apart. In order to facilitate the assembly of the aerosol generating product 1 in the aerosol generating device, the packaging layer 12 of the aerosol generating product 1 not only covers the surface of the aerosol generating matrix 11 on the side close to the heating element 31, but also bends toward the side of the aerosol generating matrix 11 to form a hanging ear 1221 so that the aerosol generating product 1 can be overlapped on the atomizing host 3; in this embodiment, the hanging ears 1221 of adjacent recesses 122 are spaced apart. That is, the packaging layer 12 is bent to form the recess 122, and the aerosol generating matrix 11 is provided in the recess 122. The distance between the annular sidewall of the recess 122 and the side of the aerosol-generating substrate 11 is 0.1 mm to 1.0 mm, which allows for better aerosol release. Optionally, the distance between the annular sidewall of the recess 122 and the side of the aerosol-generating substrate 11 is 0.2 mm to 0.3 mm. The bottom surface of the aerosol-generating substrate 11 is in contact with the bottom wall of the recess 122 to improve heating efficiency.

[0082] In another embodiment, in order to facilitate the assembly of multiple aerosol-generating articles 1 together in an aerosol-generating device, the multiple aerosol-generating articles 1 are provided as an integral structure; that is, the packaging layer 12 of the multiple aerosol-generating articles 1 is a whole layer structure, and the packaging layer 12 forms the multiple aerosol-generating articles 1 into an integral structure, such as Figure 7 As shown. Specifically, there are multiple recesses 122 formed by the encapsulation layer 12, that is, the encapsulation layer 12 is bent to form multiple recesses 122 arranged at intervals, and aerosol generating matrices 11 are provided in each of the multiple recesses 122. The annular side walls of adjacent recesses 122 are spaced apart so that adjacent aerosol generating matrices 11 are independent of each other, so that adjacent aerosol generating matrices 11 can be heated independently of each other, and adjacent aerosol generating matrices 11 are not affected by each other when heated. The ears 1221 of adjacent recesses 122 have a common part. Furthermore, in order to improve thermal efficiency, the encapsulation layer 12 is provided with a first partition hole 123 on the ear 1221 of the common part between adjacent recesses 122, which uses air insulation to reduce heat conduction between adjacent recesses 122, so that adjacent aerosol generating matrices 11 do not affect each other to the greatest extent when heated. The distance between the annular sidewall of the recess 122 and the side of the aerosol-generating substrate 11 is 0.1 mm to 1.0 mm, which allows for better aerosol release. Optionally, the distance between the annular sidewall of the recess 122 and the side of the aerosol-generating substrate 11 is 0.2 mm to 0.3 mm. The bottom surface of the aerosol-generating substrate 11 is in contact with the bottom wall of the recess 122 to improve heating efficiency.

[0083] See also Figure 8 and Figure 9 , Figure 8 : is a structural schematic diagram of the sixth embodiment of the aerosol generating article provided by the present application, Figure 9 This is another structural schematic diagram of the sixth embodiment of the aerosol generating article provided by the present application.

[0084] In the sixth embodiment of the aerosol-generating article 1 , the structure of the aerosol-generating article 1 is substantially the same as that in the fifth embodiment, except that it further comprises a cover layer 13 .

[0085] In the sixth embodiment of the aerosol-generating article 1, the aerosol-generating substrate 11 is aggregated to form a layered structure. For example, the cross-section of the aerosol-generating substrate 11 layered structure can be circular, square, rectangular, or the like, depending on the specific design. The encapsulation layer 12 covers the surface of the aerosol-generating substrate 11 on the side closest to the heating element 31, thereby separating the aerosol-generating substrate 11 from the heating element 31. Specifically, the encapsulation layer 12 encloses a recess 122, within which the aerosol-generating substrate 11 is disposed. The recess 122 includes an annular sidewall and a bottom wall, with a lug 1221 formed on the outer side of the annular sidewall to facilitate attachment of the aerosol-generating article 1 to the atomizer 3. The covering layer 13 covers at least a portion of the encapsulation layer 12 and the opening of the recess 122. The aerosol-generating substrate 11 is located between the encapsulation layer 12 and the covering layer 13. The covering layer 13 is provided with a second through hole 131 corresponding to the opening of the recess 122, for releasing aerosol. Specifically, the covering layer 13 is disposed on the surface of the encapsulation layer 12 and covers the recess 122. The covering layer 13 is provided with a second through-hole 131 corresponding to the recess 122. The primary function of the covering layer 13 is to secure the aerosol-generating substrate 11 within the recess 122. The covering layer 13 is secured to the encapsulation layer 12 by riveting, wrapping, or using high-temperature-resistant glue. The covering layer 13 is made of metal; alternatively, the covering layer 13 is made of aluminum foil. The thickness of the covering layer is 0.02 mm to 0.1 mm; alternatively, the thickness of the covering layer is 0.02 mm to 0.05 mm.

[0086] It will be understood that in this embodiment, the surface of the aerosol-generating substrate 11 in contact with the encapsulation layer 12 serves as the heating surface, and any surface of the aerosol-generating substrate 11 other than that in contact with the encapsulation layer 12 can serve as the aerosol-releasing surface, depending on specific needs. Specifically, the bottom surface of the aerosol-generating substrate 11 may mate with the bottom wall of the recess 122, and the side surfaces of the aerosol-generating substrate 11 may or may not contact the annular sidewall of the recess 122, depending on specific needs. The aerosol-generating article 1 in this embodiment can utilize either resistive heating or electromagnetic heating, depending on specific needs.

[0087] In one embodiment, the plurality of aerosol-generating articles 1 are independent of each other; that is, the packaging layers 12 of the plurality of aerosol-generating articles 1 are independent of each other, and the covering layers 13 of the plurality of aerosol-generating articles 1 are independent of each other; that is, one packaging layer 12 surrounds and forms one recess 122, and one covering layer 13 covers one recess 122. Figure 8 Specifically, the configuration of the encapsulation layer 12 is similar to Figure 6 The encapsulation layer 12 in the provided aerosol generating article 1 is provided in the same manner, and the cooperation relationship between the encapsulation layer 12 and the aerosol generating substrate 11 is the same as that of the aerosol generating article 1. Figure 6The cooperation relationship between the encapsulation layer 12 and the aerosol generating substrate 11 in the provided aerosol generating product 1 is the same and will not be described in detail.

[0088] In another embodiment, in order to facilitate the assembly of multiple aerosol-generating articles 1 together in an aerosol-generating device, the multiple aerosol-generating articles 1 are provided as an integral structure; that is, the packaging layer 12 of the multiple aerosol-generating articles 1 is a whole layer structure, and the covering layer 13 of the multiple aerosol-generating articles 1 is a whole layer structure. The packaging layer 12 and the covering layer 13 form the multiple aerosol-generating articles 1 into an integral structure, such as Figure 9 Specifically, the configuration of the encapsulation layer 12 is similar to Figure 7 The encapsulation layer 12 in the provided aerosol generating article 1 is provided in the same manner, and the cooperation relationship between the encapsulation layer 12 and the aerosol generating substrate 11 is the same as that of the aerosol generating article 1. Figure 6 The relationship between the encapsulation layer 12 and the aerosol generating substrate 11 in the provided aerosol generating product 1 is the same and will not be described in detail. Figure 7 The aerosol-generating article 1 provided, Figure 9 In the provided aerosol-generating product 1, the covering layer 13 covers a plurality of recesses 122, and second through holes 131 are provided at positions of the covering layer 13 corresponding to the recesses 122 to release aerosols; second partition holes 132 are provided on the covering layer 13 corresponding to the first partition holes 123, and air insulation is utilized to reduce heat conduction between adjacent recesses 122, so that adjacent aerosol-generating substrates 11 do not affect each other to the greatest extent possible when heated.

[0089] In the first, second, third, fourth, fifth, and sixth embodiments of the aerosol-generating article 1, the encapsulation layer 13 is made of metal; alternatively, the encapsulation layer 13 is made of copper foil or aluminum foil. To achieve higher heating efficiency, the thickness of the encapsulation layer 13 is set to 0.05 mm to 0.3 mm; alternatively, the thickness of the encapsulation layer 13 is 0.1 mm to 0.15 mm.

[0090] In the first and second embodiments of the aerosol-generating article 1, the maximum distance between two points on the cross-section of the cylindrical body of the aerosol-generating substrate 11 is 0.5 mm to 3 mm, which facilitates better heating of the aerosol-generating substrate 11 and prevents prolonged local heating of the aerosol-generating substrate 11. In the third, fourth, fifth, and sixth embodiments of the aerosol-generating article 1, the thickness of the sheet of the aerosol-generating substrate 11 is set to 0.5 mm to 3 mm. The thinner the thickness, the more conducive it is to heating the surface of the aerosol-generating substrate 11 away from the encapsulation layer 12, the shorter the time it takes for the aerosol-generating substrate 11 to be heated and used, and the avoidance of prolonged local heating of the aerosol-generating substrate 11, thereby preventing the occurrence of a burnt smell that affects the taste. Optionally, the thickness of the aerosol-generating substrate 11 is 1.0 mm to 2.0 mm.

[0091] In the fourth, fifth and sixth embodiments of the aerosol-generating article 1, the cross-sectional shape of the sheet of the aerosol-generating substrate 11 is circular, and the diameter of the aerosol-generating substrate 11 is set to 3.0 mm-20 mm; optionally, the diameter of the aerosol-generating substrate 11 is 8.0 mm-12.0 mm.

[0092] In the following description, the aerosol generating article 1 adopts the sixth embodiment. Figure 9 The structure shown.

[0093] See also Figure 10 , Figure 10 This is a structural diagram of the atomizer host provided in this application.

[0094] The atomizing host 3 also includes a housing 30, a mounting base 32, a controller 33, and a power supply 34. The housing 30 has an installation space 300; the mounting base 32 is disposed in the installation space 300 and is exposed from one end of the housing 30 to cooperate with the gas communication component 2 to form the atomizing chamber 24 (see Figure 25 The mounting seat 32 is formed with at least one mounting portion 320 for mounting an aerosol-generating article 1. The heating element 31 is disposed corresponding to the mounting portion 320 and is configured to heat the aerosol-generating article 1. A controller 33 and a power supply 34 are disposed within the mounting space 300 and on a side of the mounting seat 32 away from the gas communication assembly 2. The controller 33 controls the power supply 34 to supply power to the heating element 31. It will be appreciated that one or more aerosol-generating articles 1 may be disposed in the mounting portion 320, or one aerosol-generating article 1 may be disposed in one mounting portion 320. Specifically, the number of mounting portions 320 and the number of heating elements 31 may be the same as the number of aerosol-generating articles 1, and the design is determined based on specific needs. In the following description, it is assumed that one aerosol-generating article 1 is disposed in one mounting portion 320.

[0095] See also Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the structure of the mounting base in the atomizer host provided in this application. Figure 12 This is another structural schematic diagram of the mounting base in the atomizer host provided in this application.

[0096] In a specific implementation, at least one mounting portion 320 is formed on the mounting seat 32, which may be at least one groove 321 formed on the mounting seat 32, one groove 321 serving as a mounting portion 320, and the internal space formed by the groove 321 is the mounting position of the aerosol generating article 1 (e.g., Figure 11 As shown), that is, the groove 321 serves as a mounting portion 320 for accommodating the aerosol generating product 1; a plurality of protrusions 322 may be provided on the mounting seat 32, and the space formed by the plurality of protrusions 322 is the mounting position of the aerosol generating product 1, and the space formed by the plurality of protrusions 322 serves as a mounting portion 320 (as shown Figure 12 The arrangement of the mounting portion 320 can be designed as needed, as long as it can fix the aerosol generating product 1.

[0097] In order to improve the heating efficiency, there is a gap between the side surface of the aerosol generating product 1 and the inner side surface of the mounting portion 320 to achieve air insulation. The heating element 31 and the inner side surface of the mounting portion 320 are at least partially spaced apart to achieve air insulation between the heating element 31 and the inner wall surface of the groove 321, so that most of the heat generated by the heating element 31 to heat the aerosol generating product 1 is absorbed by the aerosol generating product 1, and a very small part is conducted to the mounting seat 32, thereby reducing heat loss.

[0098] See also Figure 13 , Figure 13 It is a partial cross-sectional schematic diagram of the first embodiment of the atomizer host provided by this application.

[0099] In the first embodiment of the atomizer main unit 3, a recess 321 is formed on the mounting base 32 as the mounting portion 320. Specifically, the mounting portion 320 forms the recess 321, and the aerosol-generating article 1 and the heating element 31 are disposed within the recess 321. Specifically, the recess 321 includes a receiving cavity (not shown) for accommodating the aerosol-generating article 1. The heating element 31 is disposed within the recess 321. When energized, the heating element 31 generates heat to heat the aerosol-generating article 1. Specifically, when energized, the heating element 31 generates heat to heat the encapsulation layer 12, which then conducts the heat to the aerosol-generating substrate 11 to form an aerosol; in other words, resistive heating of the aerosol-generating article 1 is employed. To improve heating efficiency, the heating element 31 is positioned in contact with the encapsulation layer 12 of the aerosol-generating article 1. It is understood that one or more heating elements 31 may be disposed within the mounting portion 320, as long as they can achieve uniform heating of the aerosol-generating article 1. The selection of heating elements 31 is based on specific needs. The following description assumes that one heating element 31 is provided in the mounting portion 320 .

[0100] In one embodiment, a plurality of aerosol-generating articles 1 are provided, and a mounting base 32 is formed with a plurality of mounting portions 320. Each mounting portion 320 houses a heating element 31 and an aerosol-generating article 1. Specifically, the mounting base 32 is provided with a plurality of recesses 321, with each recess 321 serving as a mounting portion 320, and each recess 321 housing an aerosol-generating article 1. The atomizer 3 includes a plurality of heating elements 31, with each heating element 31 corresponding to each mounting portion 320, i.e., each recess 321 housing a heating element 31. The pins of the heating elements 31 are electrically connected to the power supply 34 outside the housing cavity. The pins of the heating elements 31 may bypass the housing cavity to connect to the power supply 34, or they may pass through the bottom wall of the recess 321 to connect to the power supply 34.

[0101] In order to ensure uniform heating of the aerosol-generating product 1, the projection of the aerosol-generating product 1 on the heating element 31 covers at least a portion of the heating element 31, that is, the area of ​​the surface of the heating element 31 in contact with the aerosol-generating product 1 is larger than the surface area of ​​the heating element 31, so that the heating element 31 heats the entire cross-section of the aerosol-generating product 1 uniformly, which is conducive to maintaining a consistent taste.

[0102] Because the aerosol-generating article 1 and the heating element 31 are positioned within the recess 321 formed by the mounting base 32, the heating element 31 heats the aerosol-generating article 1 within the recess 321. To improve heating efficiency and minimize heat loss, the mounting base 32 is constructed from a low-thermal-conductivity, high-temperature-resistant material, such as ceramic or foam. In this embodiment, the mounting base 32 is constructed from a low-thermal-conductivity, high-temperature-resistant ceramic. To prevent interference between adjacent recesses 321, third partition holes 323 are provided between adjacent recesses 321 on the mounting base 32, further minimizing heat loss.

[0103] In order to further improve the heating efficiency, a gap is provided between the side surface of the aerosol generating product 1 and the side surface of the groove 321 to achieve air insulation; the heating element 31 and the inner wall surface of the groove 321 are at least partially spaced apart to achieve air insulation between the heating element 31 and the inner wall surface of the groove 321, so that most of the heat generated by the heating element 31 to heat the aerosol generating product 1 is absorbed by the aerosol generating product 1, and a very small part is conducted to the mounting base 32, thereby reducing heat loss.

[0104] In one embodiment, the heating element 31 includes a heating element 311 and a mounting ear 312 fixedly connected to the heating element 311. The heating element 311 is connected to the side of the groove 321 via the mounting ear 312, that is, the heating element 311 is fixed to the groove 321 via the mounting ear 312; and the heating element 311 and the bottom surface of the groove 321 are spaced apart to achieve air insulation. It is understood that the smaller the contact area between the mounting ear 312 and the side of the groove 321, the more conducive it is to reducing heat loss. The mounting ear 312 only needs to be able to fix the heating element 311 to the side of the groove 321. In multiple grooves 321, the heating element 31 is fixed to the groove 321 in the same manner.

[0105] In another embodiment, a protrusion 3211 is provided on the bottom surface of the groove 321, and the heating element 31 is provided above the protrusion 3211. The protrusion 3211 contacts a portion of the heating element 31, and the heating element 31 is at least partially spaced from the side surface of the groove 321 to achieve air insulation. It is understood that the smaller the contact area between the protrusion 3211 and the heating element 31, the more conducive it is to reducing heat loss. The protrusion 3211 can fix the heating element 31 in the groove 321. In multiple grooves 321, the heating element 31 is fixed to the groove 321 in the same manner.

[0106] In this embodiment, in order to ensure that the position of the heating element 31 is fixed and to prevent the heating element 31 from shaking in the groove 321, the heating element 31 includes a heating element 311 and a mounting ear 312 fixedly connected to the heating element 311. The heating element 311 is spaced apart from the side of the groove 321. The heating element 311 is connected to the side of the groove 321 through the mounting ear 312, and the heating element 311 is spaced apart from the bottom surface of the groove 321. A protrusion 3211 is provided on the bottom surface of the groove 321, and the heating element 311 overlaps the protrusion 3211. In other words, the heating element 311 is fixed to the groove 321 through the mounting ear 312 and the protrusion 3211. In multiple grooves 321, the heating element 31 is fixed to the groove 321 in the same manner.

[0107] By configuring the heating element 31 to heat up to 500°C within 3 seconds, the heating element 31 can rapidly bring the aerosol-generating substrate 11 in the aerosol-generating article 1 to its volatilization temperature, releasing the aerosol. Furthermore, by utilizing the high thermal conductivity of the encapsulation layer 12 in the aerosol-generating article 1, the thinness and rapid thermal conductivity of the aerosol-generating substrate 11, the low thermal conductivity and high-temperature resistance of the mounting base 32, and the air insulation between the mounting base 32, the heating element 31, and the aerosol-generating article 1, the overall thermal efficiency is improved, allowing the aerosol-generating substrate 11 in the aerosol-generating article 1 to rapidly release the aerosol.

[0108] See also Figure 14a 、 14b and Figure 15 , Figure 14a This is a cross-sectional schematic diagram of an embodiment of a heating element in the first embodiment of the atomizer host provided by this application. Figure 14b This is a cross-sectional schematic diagram of another embodiment of the heating element in the first embodiment of the atomizer host provided by this application. Figure 15 This is a schematic diagram of the three-dimensional structure of the heating element in the first embodiment of the atomizer host provided by this application.

[0109] The heating element 31 includes a heating body 311 and a mounting ear 312. The heating body 311 includes a heat-conducting base layer 319, a heating circuit layer 315, and an electrode 317; that is, the heating element 31 includes a heat-conducting base layer 319, a heating circuit layer 315, and an electrode 317. The heat-conducting base layer 319 includes a first surface and a second surface opposite to each other, and the second surface of the heat-conducting base layer 319 is used to contact the aerosol generating article 1; the heating circuit layer 315 is arranged on the first surface of the heat-conducting base layer 319. By arranging the heating circuit layer 315 on the first surface of the heat-conducting base layer 319, the temperature of the entire surface of the heat-conducting base layer 319 is uniform; that is, the entire surface of the heat-conducting base layer 319 is a high-temperature area. The electrode 317 is arranged on the surface of the heating circuit layer 315 on the side away from the heat-conducting base layer 319 and is electrically connected to the heating circuit layer 315.

[0110] The heating element 31 further includes a pin 317 a , one end of which is connected to the electrode 317 , and the other end of which is used to be connected to the power source 34 .

[0111] Existing heating elements mostly are inserted into the aerosol generating matrix, with a small part exposed outside the aerosol generating matrix. The part of the heating element inserted into the aerosol generating matrix forms a high-temperature zone to heat the aerosol generating matrix; the part exposed outside the aerosol generating matrix forms a low-temperature zone to facilitate setting the assembly fulcrum of the lead wire; a lead wire zone is provided in the low-temperature zone to set the lead wire and realize the electrical connection between the heating element and the controller. The heating element adopts a layout of high-temperature zone + low-temperature zone + lead wire zone, and uses the low-temperature zone as the assembly fulcrum, resulting in poor temperature uniformity; while the entire surface of the heating element 31 of the present application is a high-temperature zone with uniform temperature, and the electrode 317 is assembled in the high-temperature zone.

[0112] The heating element 311 of the heating element 31 in this application is a sheet-like structure. By configuring the heating element 311 as a sheet-like structure, the heating element 31 is in contact with the aerosol-generating product 1 over a large area, achieving uniform heating of the aerosol-generating product 1 and, in turn, achieving a consistent taste. The heating circuit layer 315 generates heat and conducts its heat to the thermally conductive base layer 319. To improve the heat utilization rate of the heating circuit layer 315, the thickness of the thermally conductive base layer 319 is 0.1mm-1.0mm; optionally, the thickness of the thermally conductive base layer 319 is 0.2mm. The shape of the thermally conductive base layer 319 can be circular, square, or other shapes as required.

[0113] The heat-conducting base layer 319 can be made of a heat-conducting ceramic material. The heating element 31 further includes a protective layer 316, which is arranged on the surface of the heating circuit layer 315 away from the heat-conducting base layer 319 (eg, Figure 14a The shape of the protective layer 316 is designed according to the shape of the heat-conducting base layer 319. The material of the protective layer 316 has high hardness and high temperature resistance, so as to protect the heating circuit layer 315 and improve the high temperature stability of the heating circuit layer 315. Optionally, the material of the protective layer 316 is ceramic glaze.

[0114] The heat-conducting base layer 319 can also be made of a metal material. The heating element 31 further includes an insulating layer 314 and a protective layer 316. The insulating layer 314 is disposed between the heat-conducting base layer 319 and the heating circuit layer 315. The protective layer 316 is disposed on the surface of the heating circuit layer 315 away from the insulating layer 314. In other words, the protective layer 316 is disposed on the surface of the heating circuit layer 315 away from the heat-conducting base layer 319 (e.g., Figure 14bAs shown). Specifically, the heat-conducting base layer 319 is made of a metal material with a high thermal conductivity coefficient, such as stainless steel, copper alloy, aluminum alloy, etc.; this type of material has good strength and toughness, is not easy to break, has good reliability, and has good temperature field uniformity of the heat-conducting base layer 319 under rapid temperature increase. Optionally, the material of the heat-conducting base layer 319 is 430 stainless steel. The shapes of the insulating layer 314 and the protective layer 316 are designed according to the shape of the heat-conducting base layer 319. The material of the protective layer 316 has high hardness and high temperature resistance to protect the heating circuit layer 315 and improve the high temperature stability of the heating circuit layer 315. Optionally, the material of the protective layer 316 is ceramic glaze.

[0115] Since the heating element 311 is arranged in close contact with the aerosol generating product 1, only one surface of the heating element 311 is in contact with the aerosol generating product 1, that is, only the second surface of the heat-conducting base layer 319 is in contact with the aerosol generating product 1. There is no need to provide an insulating layer 314 on both the first surface and the second surface of the heat-conducting base layer 319, and further, there is no need to provide a double-sided protective layer 316, thereby simplifying the process flow.

[0116] In order to further increase the contact area between the heating element 31 and the aerosol generating product 1, the second surface of the thermally conductive base layer 319 is set to a curved surface structure, and the corresponding surface of the aerosol generating product 1 that contacts the second surface of the thermally conductive base layer 319 is a curved surface, that is, the surface of the aerosol generating product 1 that contacts the heating element 31 is a curved surface; and the bending direction and degree of the surface of the aerosol generating product 1 that contacts the heating element 31 are set to match the bending direction and degree of the thermally conductive base layer 319.

[0117] Furthermore, the heat generated by the heating circuit layer 315 is transferred to the thermally conductive base layer 319. To achieve a uniform temperature across the entire surface of the thermally conductive base layer 319, the first surface of the thermally conductive base layer 319 is also configured as a curved surface. The curvature direction and degree of the first surface are the same as those of the second surface; that is, the first surface of the thermally conductive base layer 319 is configured as a curved surface structure corresponding to the second surface. In one embodiment, the first and second surfaces bulge away from the electrode 317. In another embodiment, the first and second surfaces bulge toward the electrode 317.

[0118] It is understood that when the thermally conductive base layer 319 is made of a metal material and both the first and second surfaces of the thermally conductive base layer 319 have curved structures, in order to achieve uniform temperature across the entire surface of the thermally conductive base layer 319, the insulating layer 314 has an arc-shaped cross-section, with the curvature direction and degree of this arc being the same as the curvature direction and degree of the second surface of the thermally conductive base layer 319. The insulating layer 314 maintains excellent stability and insulation properties even at high temperatures.

[0119] Mounting ears 312 are provided on the thermally conductive base layer 319. Specifically, multiple mounting ears 312 are spaced apart around the periphery of the thermally conductive base layer 319. The mounting ears 312 are used to secure the heating element 311. The ratio of the contact length between the mounting ears 312 and the side of the thermally conductive base layer 319 to the perimeter of the side of the thermally conductive base layer 319 is less than 1:12. The smaller the contact area between the mounting ears 312 and the thermally conductive base layer 319, the less heat is transferred from the heating element 311 to other components through the mounting ears 312, which helps reduce heat loss from the heating element 311. The mounting ears 312 only need to be sized to secure the heating element 311.

[0120] It is understood that the mounting ears 312 can be formed by extending outward from the periphery of the thermally conductive base layer 319. Optionally, the thickness of the mounting ears 312 is less than that of the thermally conductive base layer 319, which can reduce the amount of heat transferred from the heating element 311 to other components through the mounting ears 312, thereby reducing heat loss from the heating element 31. The heating element 31 is mounted in the groove 321 via the mounting ears 312. An air gap is formed between the thermally conductive base layer 319 and the sidewalls of the groove 321, utilizing air insulation to improve the energy utilization rate of the heating element 31.

[0121] The heating circuit layer 315 in the heating element 31 has a TCR characteristic and is electrically connected to the controller 33 via electrodes 317. The heating circuit layer 315 can heat up to 500°C within 3 seconds. The entire heating circuit layer 315 is a high-temperature zone; the electrodes 317 disposed on the heating circuit layer 315 are assembled in this high-temperature zone.

[0122] See also Figure 16 , Figure 16 This is a schematic structural diagram of the heating layer of the heating element in the first embodiment of the atomizer host provided by this application.

[0123] The heating circuit layer 315 is a heating circuit, bent into a pattern comprising a first section 3151, a second section 3152, and a third section 3153. The first section 3151 is positioned adjacent to the edge of the thermally conductive base layer 319 and has two opposing first notches 3154. The second section 3152 and the third section 3153 are positioned within the area enclosed by the first section 3151. Both sections 3152 and 3153 are connected to the first end 3151, and the pattern formed by the second and third sections 3152 and 3153 is symmetrically arranged. Specifically, the two ends of the second section 3152 are connected to the two ends of one of the first notches 3154 in the first section 3151, and the two ends of the third section 3153 are connected to the two ends of the other first notch 3154 in the first section 3151. There are two electrodes 317, one connected to the second section 3152 and the other connected to the third section 3153.

[0124] Exemplarily, the cross-section of the heat-conducting base layer 319 is circular; the first section 3151 of the heating circuit layer is arranged adjacent to the edge of the insulating layer 314 to form a circular ring and has two oppositely arranged first notches 3154; the second section 3152 and the third section 3153 are arranged in the circular ring formed by the first section 3151, and the second section 3152 and the third section 3153 are respectively triangular and form second notches 3155 at the top corners, and the triangles formed by the second section 3152 and the third section 3153 are symmetrically arranged; the two ends of the second notch 3155 of the second section 3152 are respectively connected to the two ends of one of the first notches 3154 of the first section 3151, and the two ends of the second notch 3155 of the third section 3153 are respectively connected to the two ends of the other first notch 3154 of the first section 3151.

[0125] In the first embodiment of the atomizer host 3, the controller 33 controls the operation of the heating element 31 to heat the aerosol-generating product 1 within the mounting portion 320 corresponding to the heating element 31. Specifically, the controller 33 can control multiple heating elements 31 to operate simultaneously, or it can control multiple heating elements 31 to operate sequentially, depending on the specific design needs. When the controller 33 controls multiple heating elements 31 to operate sequentially, the aerosol-generating products 1 within the multiple mounting portions 320 are heated sequentially. That is, after the controller 33 controls one heating element 31 to heat one aerosol-generating product 1, it controls the next heating element 31 to heat the next aerosol-generating product 1. The controller 33 controls the total operating time of each heating element 31 to be a first preset duration, which is the time it takes for the aerosol-generating substrate 11 in the aerosol-generating product 1 to be completely consumed.

[0126] The total heating time of the multiple aerosol-generating products 1 is the same as the total heating time of a conventional heat-not-burn (HNB) product. The total number of aerosol puffs that can be taken after the multiple aerosol-generating products 1 are heated is the same as the number of aerosol puffs that can be taken after the conventional heat-not-burn (HNB) product is heated. By replacing the conventional heat-not-burn (HNB) product with multiple aerosol-generating products 1, the thickness of the aerosol-generating substrate 11 in the aerosol-generating products 1 is set to 0.5 mm to 3 mm, reducing the volume of the aerosol-generating substrate. By heating the multiple aerosol-generating products 1 sequentially, it is possible to avoid prolonged heating of a portion of the aerosol-generating substrate 11, thereby preventing a burnt smell that affects the taste and improving the consistency of the taste.

[0127] In one embodiment, the controller 33 controls the next heating element 31 to start operating before the total operating time of the previous heating element 31 reaches the first preset duration. Specifically, the controller 33 controls the next heating element 31 to start operating when the total operating time of the previous heating element 31 reaches the second preset duration, and the second preset duration is shorter than the first preset duration. The difference between the second preset duration and the first preset duration is 5 seconds to 15 seconds; optionally, the difference between the second preset duration and the first preset duration is 10 seconds.

[0128] When the total working time of a heating element 31 controls by the controller 33 reaches the second preset time length, the next heating element 31 is controlled to start working, so that when the heating of an aerosol generating product 1 is coming to an end, the next aerosol generating product 1 is preheated in advance, thereby making the release amount of aerosol more stable, avoiding the sudden decrease in the aerosol release amount, and helping to improve the user experience.

[0129] In one embodiment, the controller 33 detects whether the heating process of the heating element 31 is interrupted. When the controller 33 detects an interruption in the heating process of the heating element 31 and the total operating time of the interrupted heating element 31 reaches a third preset time, the controller 33 controls the next heating element 31 to begin operating. Because the heating element 31 may still have residual heat to heat the aerosol-generating article 1 after the interruption, consuming a small amount of aerosol-generating substrate, to avoid dry heating of the heating element 31, the third preset time is shorter than the second preset time; the difference between the third preset time and the second preset time is 1 second to 5 seconds. In other words, when controlling the multiple heating elements 31 to begin operating, the controller 33 first detects whether the heating process of the heating element 31 was interrupted. If so, the controller 33 activates the interrupted heating element 31 first, i.e., heats the unconsumed aerosol-generating article 1 first. When the total heating time of the interrupted heating element 31 reaches the third preset time, the controller 33 controls the next heating element 31 to preheat the next aerosol-generating article 1.

[0130] See also Figure 17 , Figure 17 This is a schematic diagram of the relationship between heating time and temperature of the aerosol generating product provided in this application.

[0131] The controller 33 controls the continuous working time of the first heating element 31 to be a first preset duration; the first preset duration of the first heating element 31 includes: a first time period, a second time period and a third time period. The controller 33 controls the first heating element 31 to increase the temperature of the aerosol generating substrate 11 in the aerosol generating article 1 from the first temperature to the second temperature during the first time period, to decrease the temperature of the aerosol generating substrate 11 in the aerosol generating article 1 from the second temperature to the third temperature during the second time period, to maintain the aerosol generating substrate 11 in the aerosol generating article 1 at the third temperature during the third time period, and to stop heating at the end of the third time period.

[0132] The first preset duration of the first heating element 31 further includes a fourth period, which is located between the first period and the second period. During the fourth period, the aerosol-generating substrate 11 in the aerosol-generating article 1 is maintained at the second temperature.

[0133] The first time period is 5-7 seconds, the second time period is 3-5 seconds, the third time period is 22-25 seconds, and the fourth time period is 3-4 seconds. The first temperature is 20-30°C, the second temperature is 300-350°C, and the third temperature is 220-280°C. Alternatively, the first temperature is 25°C, the second temperature is 330°C, and the third temperature is 250°C. The third temperature is the temperature at which the aerosol-generating substrate 11 can release aerosol.

[0134] In one embodiment, the controller 33 controls the continuous operation time of the second, third, and fourth heating elements 31, excluding the first heating element 31, to be a first preset duration. The first preset duration of the second, third, and fourth heating elements 31, excluding the first heating element 31, includes a fifth period and a sixth period. The controller 33 controls the heating elements 31 to increase the temperature of the aerosol-generating substrate 11 in the aerosol-generating article 1 from the first temperature to the third temperature during the fifth period, maintain the aerosol-generating substrate 11 in the aerosol-generating article 1 at the third temperature during the sixth period, and stop heating at the end of the sixth period. The first period is 2 to 5 seconds, and the second period is 25 to 28 seconds.

[0135] The first heating element 31 heats the aerosol-generating substrate 11 in the first aerosol-generating article 1 to a second temperature higher than the temperature at which it releases the aerosol (the third temperature) within a first time period, which is beneficial for the aerosol-generating substrate 11 to quickly release the aerosol, so that when the user inhales the aerosol-generating device, they can inhale the aerosol in the shortest possible time, thereby improving the user's experience. It is understandable that since the next heating element 31 is started to preheat the next aerosol-generating article 1 when the heating of one heating element 31 reaches the end, the second heating element 31, the third heating element 31, and the fourth heating element 31 other than the first heating element 31 do not need to first heat the aerosol-generating substrate 11 in the corresponding second aerosol-generating article 1, the third aerosol-generating article 1, and the fourth aerosol-generating article 1 to the second temperature and then cool it to the third temperature, and can directly heat it to the third temperature. Since most of the aerosol generating matrix 11 in the corresponding aerosol generating product 1 is consumed when the heating element 31 reaches the end of heating, the concentration of the released aerosol is reduced. In order to ensure the consistency of the released aerosol concentration, the next heating element 31 is started to heat the next aerosol generating product 1 to release the aerosol when the heating of one heating element 31 reaches the end of heating to ensure the consistency of the taste.

[0136] It is understood that after the controller 33 controls one heating element 31 to operate for the second preset duration, it controls the next heating element 31 to begin operating. At this point, the next heating element 31 corresponds to an unheated aerosol-generating article 1. That is, after the controller 33 detects that the aerosol-generating substrate 11 in the aerosol-generating article 1 has been heated for the first preset duration, the controller 33 no longer controls the corresponding heating element 31 to operate, thereby preventing the heating element 31 from drying out and wasting energy. The number of mounting portions 320, heating elements 31, and aerosol-generating articles 1 is set accordingly and designed as needed.

[0137] See also Figure 18 and Figure 19 , Figure 18 This is a partial structural diagram of the second embodiment of the atomizer host provided by this application. Figure 19 It is a partial cross-sectional schematic diagram of the second embodiment of the atomizer host provided by this application.

[0138] In the second embodiment of the atomizing main unit 3, the structure of the atomizing main unit 3 is substantially the same as that of the first embodiment, and the functions and control methods of the controller 33 are the same. The difference lies in the structure of the heating element 31 and the positional relationship between the heating element 31 and the mounting portion 320. The aerosol generating product 1 provided on the atomizing main unit 3 in the second embodiment can be Figure 5-9 The aerosol-generating article 1 is shown.

[0139] In this embodiment, the heating element 31 is an electromagnetic component, which is used to provide a changing magnetic field. Specifically, the electromagnetic component includes an electromagnetic coil, and the encapsulation layer 12 is a heating layer. The heating layer generates eddy currents in the magnetic field of the electromagnetic component and generates heat to heat the aerosol generating matrix 11 to form an aerosol. That is, when the changing magnetic field generated by the electromagnetic coil penetrates the metal heating layer, eddy currents are generated to make the metal heating layer generate heat and heat the aerosol generating matrix 11. The electromagnetic coil is wound in a plane to form a disc structure, that is, after one end of the electromagnetic coil is fixed, the other end is wound along the outside of the electromagnetic coil. The electromagnetic coil is arranged on the bottom surface of the groove 321, and the side of the electromagnetic coil is spaced apart from the side of the groove 321, and the electromagnetic coil is spaced apart from the aerosol generating product 1.

[0140] Based on the working mode of the controller 33 controlling the heating element 31, an aerosol generating method is provided. Figure 20 , Figure 20 It is a flow chart of an aerosol generation method provided in this application.

[0141] The steps of the aerosol generation method are as follows:

[0142] S01: Provide a plurality of aerosol-generating articles and a plurality of heating elements.

[0143] Specifically, the aerosol-generating articles 1 and the heating elements 31 are arranged correspondingly; that is, the number of aerosol-generating articles 1 is the same as the number of heating elements 31 , and one heating element 31 heats one aerosol-generating article 1 .

[0144] The aerosol-generating article 1 comprises an aerosol-generating substrate 11 and an encapsulation layer 12 , wherein the encapsulation layer 12 covers at least a portion of the aerosol-generating substrate 11 , such that the encapsulation layer 12 separates the aerosol-generating substrate 11 from the heating element 31 .

[0145] The heating element 31 comprises a resistance wire that heats the encapsulation layer 12, causing the encapsulation layer 12 to bake the aerosol-generating substrate 11 to produce an aerosol. Alternatively, the heating element 31 comprises an electromagnetic coil. The electromagnetic coil and the encapsulation layer 12 (the encapsulation layer 12 is a heating layer) generate heat under the influence of the electromagnetic coil's magnetic field, and the encapsulation layer 12 heats the aerosol-generating substrate 11 to form an aerosol. To improve the heating efficiency of the heating element 31, the encapsulation layer 12 is positioned in close contact with the heating element 31.

[0146] S02: The controller controls the multiple heating elements to work in sequence.

[0147] Specifically, the controller 33 controls the plurality of heating elements 31 to sequentially heat the aerosol-generating article 1. The plurality of heating elements 31 operate for a first preset duration. When a heating element 31 operates for a second preset duration, the controller 33 controls the next heating element 31 to begin operating. The second preset duration is shorter than the first preset duration.

[0148] In this method, the method in which the controller 33 controls the heating element 31 can realize the functions of the controller 33 described above, which will not be described in detail here.

[0149] See also Figure 21-25 , Figure 21 is a schematic structural diagram of the gas communication component provided in this application, Figure 22 is a cross-sectional schematic diagram of a gas communication component provided in this application, Figure 23 is a cross-sectional schematic diagram of the top cover in the gas communication assembly provided in this application, Figure 24 is a cross-sectional schematic diagram of the bottom cover in the gas communication assembly provided in this application, Figure 25 It is a partial cross-sectional schematic diagram of the aerosol generating device provided in this application.

[0150] The gas communication assembly 2 includes a top cover 21 and a bottom cover 22. The top cover 21 defines a first cavity 211 and a second cavity 212, which communicate with each other. The wall of the second cavity 212 is provided with an air outlet 231 for the user to inhale. The bottom cover 22 includes a bottom cover body 221 and a protrusion 222 disposed on the bottom cover body 221. The bottom cover body 221 is disposed within the first cavity 211, and the protrusion 222 is disposed within the second cavity 212. The protrusion 222 is provided with an air outlet channel 23.

[0151] The bottom cover 22 is used to cooperate with the end of the atomizer main unit 3 equipped with the aerosol generating product 1 to form an atomization chamber 24. That is, the gas communication component 2 and the atomizer main unit 3 cooperate to form the atomization chamber 24. The aerosol generating product 1 is arranged at the end of the atomizer main unit 3 near the gas communication component 2, and the aerosol generating product 1 is located within the atomization chamber 24. Specifically, the bottom cover body 221 includes a first surface 2211 and a second surface 2212 disposed opposite the first surface 2211. The protrusion 222 is provided on the first surface 2211, and the second surface 2212 has a recess 2213. The recess 2213 cooperates with the end of the atomizer main unit 3 equipped with the aerosol generating product 1 to form the atomization chamber 24.

[0152] The bottom cover body 221 is spaced apart from the top wall of the first cavity 211 to form an air inlet channel 25; that is, the air inlet channel 25 is defined between the bottom cover 22 and the top cover 21, and the air inlet channel 25 connects the atomizing chamber 24 to the outside atmosphere, and the air outlet channel 23 connects the atomizing chamber 24 to the air outlet hole 231. By forming the air inlet channel 25 between the top cover 21 and the bottom cover 22, during the user's inhalation process, cold air from the outside continuously flows into the air inlet channel 25. As the air flows into the atomizing chamber 24, it carries heat into the air inlet channel 25, thereby cooling the top cover 21, that is, cooling the outer wall of the nozzle assembly 2, and improving the cooling efficiency to prevent high temperature from burning the user.

[0153] In order to allow external air to flow from one end of the gap between the top cover 21 and the bottom cover 22 to the other end after entering the suction nozzle assembly 2, an air inlet 251 is set on the side wall of the first cavity 211. The cavity wall of the second cavity 212 includes a top wall and an annular side wall, and the air outlet 231 is set on the top wall of the second cavity 212. The top surface of the protrusion 222 abuts the top wall of the second cavity 212, and the annular side wall of the second cavity 212 is spaced apart from the side surface of the protrusion 222. A shielding sheet 26 is provided between the annular side wall of the second cavity 212 and the side surface of the protrusion 222. The shielding sheet 26 divides the cavity formed by the protrusion 222, the second cavity 212 and the first cavity 211 into a first space 261 and a second space 262; external air enters the first space 261 through the air inlet 251, and enters the second space 262 along the extension direction of the protrusion 222 in the first space 261. It is understandable that the shielding piece 26 can be provided on the side surface of the protrusion 222 or on the annular side wall of the second cavity 212 .

[0154] See Figure 25 In this embodiment, the shielding sheet 26 is disposed on the side surface of the protrusion 222. Specifically, the shielding sheet 26 is disposed on both sides of the protrusion 222. Because the bottom cover body 221 is spaced apart from the top wall of the first cavity 211, one end of the shielding sheet 26 extends onto the bottom cover body 221, causing a portion of the shielding sheet 26 to abut against the inner wall of the first cavity 211. The other end of the shielding sheet 26 extends toward the top wall of the second cavity 212, thereby dividing the cavity formed by the protrusion 222, the second cavity 212, and the first cavity 211 into a first space 261 and a second space 262.

[0155] In one embodiment, the end of the shielding sheet 26 near the second cavity 212 abuts against the top wall of the second cavity 212, and a notch 263 is provided at the end of the shielding sheet 26 near the second cavity 212 to connect the first space 261 with the second space 262. The size of the notch 263 is designed based on the suction resistance and air intake requirements.

[0156] In another embodiment, the end of the shielding sheet 26 near the second cavity 212 abuts against the top wall of the second cavity 212, and a through hole is provided at the end of the shielding sheet 26 near the second cavity 212 to connect the first space 261 with the second space 262. The size of the through hole is designed based on the suction resistance and air intake requirements.

[0157] In another embodiment, a gap is formed between the end of the shielding sheet 26 proximal to the second cavity 212 and the top wall of the second cavity 212, thereby connecting the first space 261 with the second space 262. The distance (gap) between the end of the shielding sheet 26 proximal to the second cavity 212 and the top wall of the second cavity 212 is 4 mm to 7 mm, and the size of the gap is designed based on the required suction resistance and air intake.

[0158] In one embodiment, the bottom cover 22 further includes an elastic member 223, which is disposed on the bottom cover body 221 and is used to compress the aerosol-generating product 1, thereby ensuring a close fit between the aerosol-generating product 1 and the heating element 31 of the atomizer 3. A mounting hole 2214 is provided on the bottom wall of the recess 2213 of the bottom cover body 221 for mounting the elastic member 223. Specifically, the structural dimensions and arrangement of the mounting hole 2214 are coordinated with those of the elastic member 223.

[0159] The elastic member 223 has a recess 2231 on its surface near the aerosol generating product 1, so that the air outlet of the aerosol generating product 1 is exposed in the recess 2231, that is, the aerosol atomized by the aerosol generating product 1 is released into the recess 2231; the side wall of the recess 2231 has a through hole or notch, so that the aerosol in the recess 2231 can enter the atomization chamber 24.

[0160] The bottom cover body 221 is provided with multiple elastic members 223. One elastic member 223 is provided corresponding to the protrusion 222, and the other elastic members 223 are arranged on the bottom cover body 221 in a direction away from the protrusion 221. The elastic member 223 farthest from the protrusion 222 is provided with a first connecting hole 2232 for connecting the air inlet channel 25 with the atomizing chamber 24. The elastic member 223 corresponding to the protrusion 222 is provided with a second connecting hole 2233 for connecting the atomizing chamber 24 with the air outlet channel 23.

[0161] It can be understood that an elastic member 223 is provided on the bottom cover body 221, and at least one pit 2231 is provided on the side of the elastic member 223 close to the aerosol generating product 1. The pit 2231 is arranged corresponding to the aerosol generating product 1, and a notch or a through hole is provided on the side wall of the pit 2231 to cooperate with the aerosol generating product 1 to form an atomization chamber 24; the elastic member 223 is provided with a second connecting hole 2233 corresponding to the protrusion 222 to connect the atomization chamber 24 with the air outlet channel 23; the elastic member 223 is provided with a first connecting hole 2232 corresponding to the aerosol generating product 1 farthest from the protrusion 222 to connect the air inlet channel 25 with the atomization chamber 24.

[0162] See also Figure 26 , Figure 26 It is a gas flow diagram of the gas communication component provided in this application.

[0163] After the outside atmosphere enters the gas communication component through the air inlet 251, it flows along the extension direction of the protrusion 222 from the first space 261 through the notch 263 on the shielding sheet 26 into the second space 262, then enters the gap between the bottom cover body 221 and the top wall of the first cavity 211, and then enters the atomization chamber 24 through the first connecting hole 2232, carrying the aerosol into the air outlet channel 23 through the second connecting hole 2233, and then is inhaled by the user from the air outlet hole 231.

[0164] In order to fully carry away the aerosol in the atomization chamber 24, the through hole or notch on the side wall of the first connecting hole 2232 on the elastic member 223 farthest from the protrusion 222 is set at a position away from the adjacent elastic member 223; the through hole or notch on the side wall of the second connecting hole 2233 on the elastic member 223 corresponding to the protrusion 222 is set at a position away from the adjacent elastic member 223.

[0165] It can be understood that the structures of the gas connection component 2 and the atomizer host 3 introduced above are applicable to the structures of the fourth embodiment, the fifth embodiment and the sixth embodiment of the aerosol generating product 1 provided in this application; for the structures of the first embodiment and the third embodiment of the aerosol generating product 1 provided in this application, this application also provides an atomizer host 3 with another structure.

[0166] See also Figure 27 , Figure 27 It is a structural schematic diagram of another aerosol generating device provided in this application.

[0167] The aerosol-generating device includes an aerosol-generating article 1, a gas communication component 2, and an atomizing main unit 3. The atomizing main unit 3 includes a housing 30, a heating element 31, a controller 33, and a power supply 34. The controller 33 and power supply 34 are disposed within the cavity formed by the housing 30, with the controller 33 controlling the power supply 34 to supply power to the heating element 31. A mounting slot 35 is formed at one end of the housing 30, which is used to accommodate the heating element 31 and the aerosol-generating article 1. Specifically, the heating element 31 is disposed on the sidewall of the mounting slot 35, and the aerosol-generating article 1 is disposed within the space enclosed by the heating element 31.

[0168] The gas communication component 2 includes a cooling element 28 and a filter element 27. The cooling element 28 is arranged between the aerosol generating product 1 and the filter element 27. The cooling element 28 is a tubular body, and the tubular body forms a connecting hole. In one embodiment, one end of the cooling element 28 is inserted into the mounting groove 35 and connected to the aerosol generating product 1, and the other end is arranged outside the mounting groove 35 and connected to the filter element 27. The encapsulation layer 12 in the aerosol generating product 1 heats the aerosol generating matrix 11 to generate aerosol, and the aerosol reaches the filter element 27 through the connecting hole. In the process of the aerosol passing through the connecting hole, there is heat loss, so that the temperature of the aerosol is reduced before it is transmitted to the user's mouth through the suction filter element 27, avoiding the aerosol temperature being too high and scalding the user. The material of the cooling element 28 is a heat-resistant and dense material; for example, the material of the cooling element 28 can be plastic or ceramic.

[0169] The filter 27 is mounted on the end of the cooling element 28 that is distal to the mounting slot 35. The filter 27 covers the end of the communication hole that is distal to the mounting slot 35, allowing aerosol in the communication hole to pass through the filter 27 and into the user's mouth. The filter 27 is used to filter out aerosol-generating substrate 11 that enters the communication hole along with the aerosol airflow. The filter 27 can be made of a porous material, such as a cotton wick.

[0170] The structures of the atomizing main unit 3 and the gas communication component 2 in this embodiment are applicable to the structures of the first and third embodiments of the aerosol generating product 1 provided in this application; the heating element 31 is a resistive heating element.

[0171] See also Figure 28 , Figure 28 This is a structural schematic diagram of another aerosol generating device provided in this application.

[0172] The aerosol generating device comprises an aerosol generating product 1, a gas communication component 2 and an atomizing host 3. Figure 28 Aerosol generating device and Figure 27 The structure of the aerosol generating device is basically the same, the difference is that the heating element 31 is an electromagnetic heating element, the heating element 31 includes a spiral coil, and a mounting sleeve 36 is provided in the spiral coil for accommodating the aerosol generating product 1.

[0173] Specifically, the spiral coil and the mounting sleeve 36 are disposed together in the mounting groove 35, the spiral coil is disposed on the outer surface of the mounting sleeve 36, and the cavity formed by the mounting sleeve 36 is used to accommodate the aerosol generating product 1. In one embodiment, the spiral coil is embedded in the side wall of the mounting groove 35 (such as Figure 28 In another embodiment, the spiral coil is interference fit with the side wall of the mounting groove 35 or is fixed to the mounting groove 35 by a buckle structure.

[0174] If the heating element 31 is a resistive heating element, the present application provides an aerosol generating method, the steps are as follows:

[0175] S11: providing an aerosol-generating article, the aerosol-generating article comprising an aerosol-generating substrate and an encapsulation layer.

[0176] Specifically, the aerosol-generating article 1 comprises an aerosol-generating substrate 11 and an encapsulation layer 12 , wherein the encapsulation layer 12 covers at least a portion of the aerosol-generating substrate 11 , so that the encapsulation layer 12 separates the aerosol-generating substrate 11 from the heating element 31 .

[0177] S12: The heating element heats the packaging layer, so that the packaging layer bakes the aerosol generating matrix to generate aerosol.

[0178] Specifically, the heating element 31 is used to heat the aerosol-generating article 1. The heating element 31 comprises a resistance wire that heats the encapsulation layer 12, causing the encapsulation layer 12 to bake the aerosol-generating substrate 11 to generate aerosol. In other words, the heating element 31 heats the encapsulation layer 12, causing the encapsulation layer 12 to bake the aerosol-generating substrate 11 to generate aerosol. To improve the heating efficiency of the heating element 31, the encapsulation layer 12 is positioned in close contact with the heating element 31.

[0179] Any combination of the above-described structures of the aerosol generating product 1 , the nozzle assembly 2 , and the atomizing host 3 can be used to implement the method. Therefore, the device structure corresponding to the method will not be described in detail.

[0180] If the heating element 31 is an electromagnetic heating element, the present application provides an aerosol generating method, the steps are as follows:

[0181] S31: Providing an aerosol-generating article, the aerosol-generating article comprising an aerosol-generating substrate and an encapsulation layer.

[0182] Specifically, the aerosol-generating article 1 comprises an aerosol-generating substrate 11 and an encapsulation layer 12 , wherein the encapsulation layer 12 covers at least a portion of the aerosol-generating substrate 11 , so that the encapsulation layer 12 separates the aerosol-generating substrate 11 from the heating element 31 .

[0183] S32: Providing a changing magnetic field to the aerosol generating article through an electromagnetic component, thereby generating eddy currents in the packaging layer and generating heat, thereby heating the aerosol generating matrix.

[0184] Specifically, the heating element 31 is an electromagnetic component. When the electromagnetic component is energized, a changing magnetic field is generated. When the changing magnetic field generated by the electromagnetic component penetrates the packaging layer 12, eddy currents are generated to heat the packaging layer 12 and heat the aerosol generating matrix 11.

[0185] Any combination of the above-described structures of the aerosol generating product 1 , the nozzle assembly 2 , and the atomizing host 3 can be used to implement the method. Therefore, the device structure corresponding to the method will not be described in detail.
