The atomizing main unit 3 includes a heating element 31, which is arranged at the end of the atomizing main unit 3 close to the gas connection component 2, and the aerosol generating product 1 is arranged at one end of the atomizing main unit 3 close to the gas connection component 2; that is, the aerosol generating product 1 is arranged between the gas connection component 2 and the atomizing main unit 3, and the aerosol generating product 1 is in contact with the heating element 31. The aerosol generating product 1 is fixed by connecting and fixing the gas connection component 2 and the atomizing main unit 3.

The connection method of the gas communication component 2 and the atomizer host 3 is designed according to needs, and this application does not limit this.

[0052] See also Figure 2 , Figure 2 It is a structural schematic diagram of the first embodiment of the aerosol generating product provided by the present application.

[0053] 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. The aerosol generating article 1 is replaceable and can be used as a disposable product. The area of ​​the aerosol generating substrate 11 covered by the encapsulation layer 12 is selected according to the specific implementation, as long as the encapsulation layer 12 can separate 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 such that the aerosol generating substrate 11 and the heating element 31 cannot directly contact each other.

[0054] The heating element 31 is used to heat the encapsulation layer 12, and the encapsulation layer 12 conducts heat to the aerosol generating substrate 11 in the aerosol generating product 1 to form an aerosol, that is, the aerosol generating product 1 is heated by resistance; or the heating element 31 is an electromagnetic component, such as an electromagnetic coil, and the encapsulation layer 12 generates eddy current heating in the magnetic field of the electromagnetic component to heat the aerosol generating substrate 11 to form an aerosol, that is, the aerosol generating product 1 is heated by electromagnetic heating. When the aerosol generating product 1 is heated by electromagnetic heating, the encapsulation layer 12 is a heating layer, and the heating layer generates eddy current self-heating in the magnetic field of the heating element 31 (electromagnetic component), and heats the aerosol generating substrate 11 to form an aerosol.

[0055] When resistive heating is used to generate the aerosol product 1, the encapsulation layer 12 has the property of uniform thermal conductivity and can be made of glass, ceramic, metal, etc., as long as the requirements are met; that is, the encapsulation layer 12 can be a metal layer, a ceramic layer, or a glass layer. It is understandable that the uniform thermal conductivity of the encapsulation layer 12 enables the aerosol generating matrix 11 to be uniformly heated, which is beneficial to improving the consistency of the aerosol quality, that is, improving the consistency of the taste. When electromagnetic heating is used to generate the aerosol product 1, the encapsulation layer 12 is made of a metal that can generate heat in a magnetic field, such as aluminum foil.

[0056] By configuring the aerosol generating product 1 to include an aerosol generating substrate 11 and an encapsulation layer 12, and the encapsulation layer 12 covers 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, avoiding direct contact between the heating element 31 and the aerosol generating substrate 11, and thus avoiding the aerosol residue 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, and even if the heating element 31 is reused, it will not affect the taste of the aerosol, thereby improving the user's experience. Moreover, by covering at least a portion of the aerosol generating substrate 11 with the encapsulation layer 12, 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 product 1 is used, making the replacement of the aerosol generating substrate 11 more convenient, fast and clean.

[0057] In a specific implementation, the aerosol generating matrix 11 can be in the form of powder, filament, or aggregated to form a block. The aerosol generating matrix 11 is in the form of powder or filament. Since the powder or filament cannot be shaped, a mold is required to lay the encapsulation layer 12 in the mold, and the aerosol generating matrix 11 is used for filling, thereby obtaining 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; and the aerosol generating matrix 11 can be designed into a columnar body, a layered body or other shapes as needed, thereby obtaining the desired shape of the aerosol generating product 1. In the following description, the aerosol generating matrix 11 is introduced as a block.

[0058] It is understandable that the packaging 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 a higher heating efficiency, this portion of the packaging layer 12 is arranged in close contact with the aerosol generating substrate 11 .

[0059] In the first embodiment of the aerosol generating product 1, the aerosol generating matrix 11 is gathered to form a columnar body, and the encapsulation layer 12 is set to be a hollow columnar body and covers the side of the aerosol generating matrix 11. For example, the encapsulation layer 12 can be in the form of a sheet, which is formed into a hollow columnar body by winding; the encapsulation layer 12 can also be in the form of a strip, which is formed into a hollow columnar body by spiral winding. The aerosol generating product 1 in this embodiment can use resistive heating or electromagnetic heating, which is selected according to needs. It can be understood that the side of the aerosol generating matrix 11 in this embodiment is the heating surface, and the bottom surface is the aerosol release surface.

[0060] 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 matched with the structural dimensions of the aerosol generating substrate 11, and it is sufficient that the encapsulation layer 12 completely covers the side of the aerosol generating substrate 11. In order to ensure a high heating efficiency, the encapsulation layer 12 is arranged in a close fit with the side of the aerosol generating substrate 11.

[0061] 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. Among them, 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 in contact with 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.

[0062] In one embodiment, the aerosol generating substrate 11 is aggregated to form a columnar body, and the heating layer surrounds 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 are spaced apart from each other. Both opposite ends of the hollow tubular body are open ends, and the heating layer covers the side of the aerosol generating substrate 11. The structure is as follows: Figure 2 As shown; 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.

[0063] 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, and the structure is as follows Figure 2 As shown. It can be understood that the cross-sectional shape of the aerosol generating substrate 11 can be circular, triangular, etc.; 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-20 mm. Among them, the heating layer is aluminum foil or copper foil, and the thickness of the heating layer is 0.05 mm-0.3 mm.

[0064] 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.

[0065] See also Figure 3 , Figure 3 It is a structural schematic diagram of the second embodiment of the aerosol generating product provided by the present application.

[0066] In the second embodiment of the aerosol generating product 1, the aerosol generating matrix 11 is gathered to form a columnar body; illustratively, the aerosol generating matrix 11 can be a cylinder, a triangular prism, a quadrangular prism, etc. An insertion groove 111 is provided on the aerosol generating matrix 11, the encapsulation layer 12 is provided in the insertion groove 111 and covers the inner wall of the insertion groove 111, and the heating element 31 is inserted into the cavity 120 formed by the encapsulation layer 12. The aerosol generating product 1 in this embodiment adopts resistive heating. It can be understood that the inner wall surface of the insertion groove 111 of the aerosol generating matrix 11 in this embodiment is the heating surface, and the outer surface of the aerosol generating matrix 11 can be used as the aerosol release surface, which is specifically designed according to needs. In one embodiment, the encapsulation layer 12 can also be folded into a multi-layer structure and inserted into the aerosol generating matrix 11, and the sheet-like heating element 31 is inserted between the layers of the encapsulation layer 12 when used, so as to avoid the heating element 31 from contacting the aerosol generating matrix 11.

[0067] See also Figure 4 , Figure 4 It is a structural schematic diagram of the third embodiment of the aerosol generating product provided by the present application.

[0068] In the third embodiment of the aerosol generating product 1, the aerosol generating substrate 11 is aggregated to form a layered body, and the encapsulation layer 12 is stacked with the aerosol generating substrate 11 and rolled together into a columnar or column-like shape, such as a spring roll shape, so that the outer surface of the aerosol generating substrate 11 is wrapped by the encapsulation layer 12, and the encapsulation layer 12 is also arranged inside; that is, the encapsulation layer 12 has a first end and a second end, and the second end is rolled around the first end to form a roll, and the aerosol generating substrate 11 is filled in the gap of the rolled encapsulation layer 12. Exemplarily, the cross-section of the aerosol generating substrate 11 layered body can be square, rectangular, etc., and the column formed by the aerosol generating substrate 11 and the encapsulation layer 12 rolling together can be a cylinder, a triangular prism, a quadrangular prism, etc. The aerosol generating product 1 in this embodiment can use resistive heating or electromagnetic heating, which can be selected according to needs.

[0069] It can be understood that the cylindrical side formed by the aerosol generating substrate 11 and the encapsulation layer 12 curling together in this embodiment is the heating surface, and the bottom surface is the aerosol releasing surface. The structural dimensions of the encapsulation layer 12 are matched with the structural dimensions of the layered body of the aerosol generating substrate 11, so that the encapsulation layer 12 and the aerosol generating substrate 11 are curled together, and the encapsulation layer 12 is ensured to separate the aerosol generating substrate 11 from the heating element 31.

[0070] 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. The heating layer is curled, and 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 matrix 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 matrix 11, and the second end of the heating layer is located outside the aerosol generating matrix 11. Among them, the inner wall surface of the receiving space is the first surface 127 of the heating layer, and the part of the second surface 128 of the heating layer curled into the aerosol generating matrix 11; the outer wall surface of the receiving space is the part of the second surface 128 of the heating layer that is not curled into the aerosol generating matrix 11 and is not in contact with the aerosol generating matrix 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.

[0071] 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.

[0072] In the fourth embodiment of the aerosol generating product 1, the aerosol generating substrate 11 is aggregated to form a layered body, and the encapsulation layer 12 covers the entire outer surface of the aerosol generating substrate 11; and a first through hole 121 is provided on 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 product 1 in this embodiment can use resistive heating or electromagnetic heating, which is selected according to the needs.

[0073] For example, the cross-section of the aerosol generating substrate 11 layer can be circular, square, rectangular, etc., and can be designed specifically according to needs. It can be understood 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 all heating surfaces, and the surface of the aerosol generating substrate 11 corresponding to the first through hole 121 on the encapsulation layer 12 is the aerosol release surface.

[0074] See also Figure 6 and Figure 7 , Figure 6 is a schematic structural diagram of a fifth embodiment of an aerosol generating article provided in the present application, Figure 7It is another structural schematic diagram of the fifth embodiment of the aerosol generating article provided by the present application.

[0075] In the fifth embodiment of the aerosol generating product 1, the aerosol generating matrix 11 is aggregated to form a layered body. For example, the cross-section of the layered body of the aerosol generating matrix 11 can be circular, square, rectangular, etc., and is specifically designed according to needs. The encapsulation layer 12 covers the surface of the aerosol generating matrix 11 close to the heating element 31, so as to separate the aerosol generating matrix 11 from the heating element 31. In other words, the encapsulation layer 12 is surrounded to form a recess 122, and the aerosol generating matrix 11 is arranged in the recess 122. The recess 122 includes an annular side wall and a bottom wall, and the outer side of the annular side wall has a hanging ear 1221, so that the aerosol generating product 1 can be overlapped on the atomizing host 3.

[0076] It can be understood that in this embodiment, the surface of the aerosol generating substrate 11 in contact with the encapsulation layer 12 is the heating surface, and the surface of the aerosol generating substrate 11 other than the surface in contact with the encapsulation layer 12 can be the aerosol release surface, which is specifically designed according to needs. That is, the bottom surface of the aerosol generating substrate 11 is in contact with the bottom wall of the recess 122, and the side surface of the aerosol generating substrate 11 may be in contact with the annular side wall of the recess 122, or may not be in contact, which is specifically designed according to needs. The aerosol generating product 1 in this embodiment can use resistive heating or electromagnetic heating, which is specifically selected according to needs.

[0077] 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 arranged in each recess 122, and adjacent recesses 122 are arranged at intervals. In order to facilitate the assembly of the aerosol generating product 1 in the aerosol generating device, in addition to covering the surface of the aerosol generating matrix 11 on the side close to the heating element 31, the packaging layer 12 of the aerosol generating product 1 is also bent 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 arranged at intervals. In other words, the packaging layer 12 is bent to form the recess 122, and the aerosol generating matrix 11 is arranged in the recess 122. The distance between the annular side wall of the recess 122 and the side of the aerosol generating substrate 11 is 0.1 mm-1.0 mm, which is used to better release the aerosol; optionally, the distance between the annular side wall of the recess 122 and the side of the aerosol generating substrate 11 is 0.2 mm-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 the heating efficiency.

[0078] 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 arranged 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 is used to form 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 substrates 11 are arranged in each of the multiple recesses 122. The annular side walls of adjacent recesses 122 are arranged at intervals so that adjacent aerosol generating substrates 11 are independent of each other, so that adjacent aerosol generating substrates 11 can be heated independently of each other, and adjacent aerosol generating substrates 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 ears 1221 of the common part between adjacent recesses 122, and air insulation is used to reduce heat conduction between adjacent recesses 122, so that adjacent aerosol generating substrates 11 are not affected by each other to the greatest extent when heated.

[0080] 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 a cover layer 13 is further included.

[0081] In the sixth embodiment of the aerosol generating product 1, the aerosol generating substrate 11 is aggregated to form a layered body. For example, the cross-section of the aerosol generating substrate 11 layered body can be circular, square, rectangular, etc., and can be designed specifically according to needs. The encapsulation layer 12 covers the surface of the aerosol generating substrate 11 close to the heating element 31, so as to separate the aerosol generating substrate 11 from the heating element 31.

The thickness of the covering layer is 0.02mm-0.1mm; optionally, the thickness of the covering layer is 0.02mm-0.05mm.

[0082] It can be understood that in this embodiment, the surface of the aerosol generating substrate 11 in contact with the encapsulation layer 12 is the heating surface, and the surface of the aerosol generating substrate 11 other than the surface in contact with the encapsulation layer 12 can be the aerosol release surface, which is specifically designed according to needs. That is, the bottom surface of the aerosol generating substrate 11 is in contact with the bottom wall of the recess 122, and the side surface of the aerosol generating substrate 11 may be in contact with the annular side wall of the recess 122, or may not be in contact, which is specifically designed according to needs. The aerosol generating product 1 in this embodiment can use resistive heating or electromagnetic heating, which is specifically selected according to needs.

[0083] 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, such as 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 arranged in the same manner, and the matching relationship between the encapsulation layer 12 and the aerosol generating substrate 11 is the same as Figure 6The matching 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.

[0084] In another embodiment, in order to facilitate the assembly of multiple aerosol generating products 1 together in an aerosol generating device, the multiple aerosol generating products 1 are arranged as an integral structure; that is, the packaging layer 12 of the multiple aerosol generating products 1 is a whole layer structure, and the covering layer 13 of the multiple aerosol generating products 1 is a whole layer structure, and the multiple aerosol generating products 1 are formed into an integral structure by the packaging layer 12 and the covering layer 13. Fig. 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 arranged in the same manner, and the matching relationship between the encapsulation layer 12 and the aerosol generating substrate 11 is the same as Figure 6 The matching 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, Fig. 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 when being heated.

[0085] In the first, second, third, fourth, fifth and sixth embodiments of the aerosol generating article 1, the material of the encapsulation layer 13 is metal; optionally, the material of the encapsulation layer 13 is copper foil or aluminum foil. In order to achieve higher heating efficiency, the thickness of the encapsulation layer 13 is set to 0.05 mm-0.3 mm; optionally, the thickness of the encapsulation layer 13 is 0.1 mm-0.15 mm.

[0086] In the first and second embodiments of the aerosol generating product 1, the farthest distance between two points on the cross section of the columnar body of the aerosol generating substrate 11 is 0.5 mm-3 mm, which is conducive to better heating of the aerosol generating substrate 11 and can prevent the aerosol generating substrate 11 from being locally heated for a long time. In the third, fourth, fifth and sixth embodiments of the aerosol generating product 1, the thickness of the sheet of the aerosol generating substrate 11 is set to 0.5 mm-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, and the shorter the time it takes for the aerosol generating substrate 11 to be heated and used, which can prevent the aerosol generating substrate 11 from being locally heated for a long time, thereby preventing the occurrence of burnt smell affecting the taste; optionally, the thickness of the aerosol generating substrate 11 is 1.0 mm-2.0 mm.

[0087] In the fourth, fifth and sixth embodiments of the aerosol generating product 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 3.0mm-20mm; optionally, the diameter of the aerosol generating substrate 11 is 8.0mm-12.0mm.

[0088] In the following description, the aerosol generating article 1 adopts the sixth embodiment as shown in FIG. Fig. 9 The structure shown.

[0089] See also Fig.10 , Fig.10 It is a structural schematic diagram of the atomizer host provided in this application.

[0090] The atomizing host 3 further includes a housing 30, a mounting seat 32, a controller 33 and a power supply 34. The housing 30 has an installation space 300; the mounting seat 32 is disposed in the installation space 300 and exposed from one end of the housing 30 to cooperate with the gas communication component 2 to form an atomizing chamber 24 (see Fig.25 ); the mounting seat 32 is formed with at least one mounting portion 320, the mounting portion 320 is used to mount the aerosol generating product 1, and the heating element 31 is arranged corresponding to the mounting portion 320, and is used to heat the aerosol generating product 1; the controller 33 and the power supply 34 are arranged in the mounting space 300 and are located on the side of the mounting seat 32 away from the gas communication component 2, and the controller 33 controls the power supply 34 to supply power to the heating element 31. It can be understood that one or more aerosol generating products 1 can be arranged in the mounting portion 320; or one aerosol generating product 1 can be arranged in one mounting portion 320, that is, the number of the mounting portions 320 and the number of the heating elements 31 are the same as the number of the aerosol generating products 1, and the specific design is carried out according to the needs. In the following introduction, it is assumed that one aerosol generating product 1 is arranged in one mounting portion 320.

[0091] See also Fig.11 and Fig.12 , Fig.11 This is a schematic diagram of the structure of the mounting seat in the atomizer host provided by this application. Fig.12 This is another structural schematic diagram of the mounting seat in the atomizer host provided by the present application.

[0092] In a specific implementation, at least one mounting portion 320 is formed on the mounting seat 32, and at least one groove 321 may be formed on the mounting seat 32, one groove 321 serves as a mounting portion 320, and the internal space formed by the groove 321 is the mounting position of the aerosol generating article 1 (such as Fig.11 As shown), that is, the groove 321 is used as a mounting portion 320 for accommodating the aerosol generating product 1; it is also possible to set a plurality of protrusions 322 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 is used as a mounting portion 320 (as shown Fig.12 The installation method of the mounting portion 320 can be designed as required, as long as it can fix the aerosol generating product 1.

[0093] In order to improve the heating efficiency, there is a gap between the side of the aerosol generating product 1 and the inner side of the mounting portion 320 to achieve air insulation, and the heating element 31 and the inner side of the mounting portion 320 are at least partially spaced apart to achieve air insulation between the heating element 31 and the inner wall 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.

[0094] See also Fig.13 , Fig.13 It is a partial cross-sectional schematic diagram of the first embodiment of the atomizer host provided by the present application.

[0095] In the first embodiment of the atomizer host 3, a groove 321 is formed on the mounting seat 32 as the mounting portion 320, that is, the mounting portion 320 forms a groove 321, and the aerosol generating product 1 and the heating element 31 are arranged in the groove 321. Specifically, the groove 321 includes a housing cavity (not shown), and the housing cavity is used to accommodate the aerosol generating product 1. A heating element 31 is arranged in the groove 321, and the heating element 31 generates heat under power-on conditions to heat the aerosol generating product 1. Specifically, the heating element 31 generates heat under power-on conditions to heat the encapsulation layer 12, and the encapsulation layer 12 conducts the heat to the aerosol generating matrix 11 to form an aerosol; that is, the aerosol generating product 1 is heated by resistance. In order to improve the heating efficiency, the heating element 31 is arranged in contact with the encapsulation layer 12 of the aerosol generating product 1. It can be understood that one or more heating elements 31 can be arranged in the mounting portion 320, and the aerosol generating product 1 can be uniformly heated, and it can be selected according to needs. The following description will be made assuming that a heating element 31 is disposed in the mounting portion 320 .

[0096] In one embodiment, a plurality of aerosol generating products 1 are provided, and a plurality of mounting portions 320 are formed on the mounting seat 32, and a heating element 31 and an aerosol generating product 1 are provided in each mounting portion 320. That is, a plurality of grooves 321 are provided on the mounting seat 32, and one groove 321 serves as a mounting portion 320, and one aerosol generating product 1 is provided in one groove 321; the atomizing host 3 includes a plurality of heating elements 31, and one heating element 31 is provided corresponding to one mounting portion 320, that is, one heating element 31 is provided in one groove 321. The pins of the heating element 31 are electrically connected to the power supply 34 outside the accommodating cavity. The pins of the heating element 31 bypass the accommodating cavity to connect to the power supply 34, or the pins of the heating element 31 pass through the bottom wall of the groove 321 to connect to the power supply 34.

[0097] In order to heat the aerosol generating product 1 evenly, the projection of the aerosol generating product 1 on the heating element 31 at least covers 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 area of ​​the surface of the heating element 31, so that the heating element 31 heats the entire cross-section of the aerosol generating product 1 evenly, which is conducive to maintaining a consistent taste.

[0098] Since the aerosol generating product 1 and the heating element 31 are arranged in the groove 321 formed by the mounting seat 32, that is, the heating element 31 heats the aerosol generating product 1 in the groove 321, in order to improve the heating efficiency and reduce the heat loss, the mounting seat 32 is made of a low thermal conductivity and high temperature resistant material, such as ceramics, foam, etc. In this embodiment, the mounting seat 32 is made of low thermal conductivity and high temperature resistant ceramics. In order to avoid mutual influence between adjacent grooves 321, a third partition hole 323 is provided between adjacent grooves 321 on the mounting seat 32, which further reduces the heat loss.

[0099] In order to further improve the heating efficiency, there is a gap between the side of the aerosol generating product 1 and the side 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 of the heating element 31 heating 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.

[0100] 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 through the mounting ear 312, that is, the heating element 311 is fixed to the groove 321 through 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 can be understood that the smaller the contact area between the mounting ear 312 and the side of the groove 321, the more conducive to reducing heat loss, and the mounting ear 312 can fix the heating element 311 on the side of the groove 321. In multiple grooves 321, the heating element 31 is fixed to the groove 321 in the same manner.

[0101] 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 part of the heating element 31, and the heating element 31 and the side of the groove 321 are at least partially spaced apart to achieve air insulation. It is understandable that the smaller the contact area between the protrusion 3211 and the heating element 31, the more conducive to reducing heat loss, and 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.

[0102] In this embodiment, in order to ensure the fixed position of the heating element 31 and 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 in 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 way.

[0103] The heating element 31 is set to be able to heat up to 500° C. within 3 seconds, so that the heating element 31 can quickly make the aerosol-generating substrate 11 in the aerosol-generating product 1 reach its volatilization temperature to release the aerosol. Furthermore, by utilizing the high thermal conductivity of the encapsulation layer 12 in the aerosol-generating product 1, the thin thickness and fast thermal conductivity of the aerosol-generating substrate 11, the low thermal conductivity and high temperature resistance of the mounting seat 32, and the air insulation between the mounting seat 32, the heating element 31 and the aerosol-generating product 1, the overall thermal efficiency is improved, so that the aerosol-generating substrate 11 in the aerosol-generating product 1 can quickly release the aerosol.

Fig.14b It is a cross-sectional schematic diagram of another embodiment of the heating element in the first embodiment of the atomizer host provided by the present application. Fig.15 It is a schematic diagram of the three-dimensional structure of the heating element in the first embodiment of the atomizer host provided by the present application.

[0105] 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 product 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.

[0106] 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 .

[0107] In the prior art, most of the heating element is inserted into the aerosol generating matrix, and a small part is 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 the setting of 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, and the temperature uniformity is poor; 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.

[0108] The heating element 311 of the heating element 31 in the present application is a sheet structure. By setting the heating element 311 as a sheet structure, the heating element 31 is in contact with the aerosol generating product 1 over a large area, so as to achieve uniform heating of the aerosol generating product 1, and thus achieve consistency in taste. The heating circuit layer 315 generates heat and conducts its heat to the heat-conducting base layer 319. In order to improve the heat utilization rate of the heating circuit layer 315, the thickness of the heat-conducting base layer 319 is 0.1mm-1.0mm; optionally, the thickness of the heat-conducting base layer 319 is 0.2mm. The shape of the heat-conducting base layer 319 can be made into a circle, a square, etc. according to requirements.

[0109] 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 disposed on a surface of the heating circuit layer 315 away from the heat-conducting base layer 319 (eg, Fig.14a The shape of the protective layer 316 is designed according to the shape of the heat conductive 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.

[0110] 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. That is, 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., Fig.14bAs shown). Specifically, the heat-conducting base layer 319 is made of a metal material with a high thermal conductivity, 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 uniformity of the temperature field of the heat-conducting base layer 319 under rapid temperature rise. 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.

[0111] 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 thermal conductive base layer 319 is in contact with the aerosol generating product 1. There is no need to set an insulating layer 314 on both the first surface and the second surface of the thermal conductive base layer 319, and further, there is no need to set a double-sided protective layer 316, thereby simplifying the process flow.

[0112] 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 coordinated with the bending direction and degree of the thermally conductive base layer 319.

[0113] Furthermore, the heating circuit layer 315 generates heat and conducts its heat to the heat-conducting base layer 319. In order to achieve uniform temperature on the entire surface of the heat-conducting base layer 319, the first surface of the heat-conducting base layer 319 is also set as a curved surface, and the bending direction and degree of the first surface are the same as the bending direction and degree of the second surface; that is, the first surface of the heat-conducting base layer 319 is set as a curved surface structure corresponding to the second surface. In one embodiment, the convex direction of the first surface and the second surface is the direction away from the electrode 317. In another embodiment, the convex direction of the first surface and the second surface is the direction close to the electrode 317.

[0114] It is understandable that when the heat conductive base layer 319 is made of a metal material, and the first surface and the second surface of the heat conductive base layer 319 are both arc structures, in order to achieve uniform temperature on the entire surface of the heat conductive base layer 319, the cross section of the insulating layer 314 is an arc, and the bending direction and degree of the arc are the same as the bending direction and degree of the second surface of the heat conductive base layer 319. The insulating layer 314 still has excellent stability and insulation performance at high temperatures.

[0115] The mounting ears 312 are arranged on the heat-conducting base layer 319. Specifically, a plurality of spaced mounting ears 312 are arranged on the periphery of the heat-conducting base layer 319. The mounting ears 312 are used to fix the heating element 31. The ratio of the contact length between the mounting ears 312 and the side of the heat-conducting base layer 319 and the perimeter of the side thereof is less than 1:12. The smaller the contact area between the mounting ears 312 and the heat-conducting base layer 319, the less heat the heating element 311 conducts to other components through the mounting ears 312, which is more conducive to reducing the heat loss of the heating element 31. The size setting of the mounting ears 312 can achieve the fixing of the heating element 311.

[0116] It is understandable that the mounting ears 312 can be formed by extending outward from the periphery of the heat-conducting base layer 319. Optionally, the thickness of the mounting ears 312 is less than the thickness of the heat-conducting base layer 319, which can reduce the heat conducted from the heating element 311 to other components through the mounting ears 312, and is conducive to reducing the heat loss of the heating element 31. The heating element 31 is installed in the groove 321 through the mounting ears 312, and an air gap is formed between the heat-conducting base layer 319 and the side wall of the groove 321, and air insulation is used to improve the energy utilization rate of the heating element 31.

[0117] The heating circuit layer 315 in the heating element 31 has a TCR characteristic, and the heating circuit layer 315 is electrically connected to the controller 33 through the electrode 317. The heating circuit layer 315 can be heated to 500°C within 3 seconds. The entire heating circuit layer 315 is a high temperature area; the electrode 317 disposed on the heating circuit layer 315 is assembled in the high temperature area.

[0118] See also Fig.16 , Fig.16 It is a schematic diagram of the structure of the heating layer of the heating element in the first embodiment of the atomizer host provided by the present application.

[0119] The heating circuit layer 315 is a heating circuit, and the heating circuit is bent into a pattern including a first section 3151, a second section 3152, and a third section 3153; the first section 3151 is arranged adjacent to the edge of the heat-conducting base layer 319 and has two first notches 3154 arranged opposite to each other; the second section 3152 and the third section 3153 are arranged in the area enclosed by the first section 3151, and the second section 3152 and the third section 3153 are both connected to the first end 3151, and the pattern enclosed by the second section 3152 and the third section 3153 is arranged symmetrically. Specifically, the two ends 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 third section 3153 are respectively connected to the two ends of the other first notch 3154 of the first section 3151. There are two electrodes 317, one electrode 317 is connected to the second section 3152, and the other electrode 317 is connected to the third section 3153.

[0120] 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 triangles and form second notches 3155 at the vertex, 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.

[0121] In the first embodiment of the atomizer host 3, the controller 33 controls the heating element 31 to work, so as to heat the aerosol generating product 1 in the installation part 320 corresponding to the heating element 31; specifically, the controller 33 can control multiple heating elements 31 to work simultaneously, or control multiple heating elements 31 to work in sequence, and the specific design is based on the needs. When the controller 33 controls multiple heating elements 31 to work in sequence, the aerosol generating products 1 in multiple installation parts 320 are heated in sequence; 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 working time of each heating element 31 to be the first preset time length, and the first preset time length is the time for the aerosol generating matrix 11 in the aerosol generating product 1 to be consumed.

[0122] The total heating time of the multiple aerosol generating products 1 is the same as the total heating time of the traditional heat-not-burn product (HNB), and the total number of puffs of aerosol that can be inhaled after the multiple aerosol generating products 1 are heated is the same as the number of puffs of aerosol that can be inhaled after the traditional heat-not-burn product (HNB) is heated. By replacing the traditional heat-not-burn product (HNB) with multiple aerosol generating products 1, the thickness of the aerosol generating matrix 11 in the aerosol generating products 1 is set to 0.5mm-3mm, the volume of the aerosol generating matrix is ​​reduced, and the multiple aerosol generating products 1 are heated in sequence, which can avoid the aerosol generating matrix 11 from being heated for a long time locally, thereby avoiding the occurrence of burnt smell affecting the taste and improving the consistency of the taste.

[0123] In one embodiment, the controller 33 controls the next heating element 31 to start working in advance before the total working time of a heating element 31 reaches the first preset time. Specifically, the controller 33 controls the next heating element 31 to start working when the total working time of a heating element 31 reaches the second preset time, and the second preset time is shorter than the first preset time. The difference between the second preset time and the first preset time is 5 seconds to 15 seconds; optionally, the difference between the second preset time and the first preset time is 10 seconds.

[0124] When the total working time of a heating element 31 controls by the controller 33 reaches a 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 a sudden decrease in the release amount of aerosol, which is beneficial to improving the user experience.

[0125] In one embodiment, the controller 33 detects whether the heating process of the heating element 31 is interrupted. When the controller 33 detects that the heating process of the heating element 31 is interrupted, and the total working time of the interrupted heating element 31 reaches the third preset time, the next heating element 31 is controlled to start working. Since the heating element 31 has not reached the first preset time, the heating will still have residual heat to heat the aerosol generating product 1 after the heating is interrupted, and a small amount of aerosol generating substrate will be consumed. In order to avoid dry burning 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. That is, when the controller 33 controls multiple heating elements 31 to start working, it first detects whether there is a heating element 31 interrupted during the heating process. If so, the interrupted heating element 31 is operated first, that is, the unconsumed aerosol generating product 1 is heated first, and when the total heating time of the interrupted heating element 31 reaches the third preset time, the next heating element 31 is made to preheat the next aerosol generating product 1.

[0126] See also Fig.17 , Fig.17 It is a schematic diagram of the relationship between heating time and temperature of the aerosol generating product provided in the present application.

[0127] The controller 33 controls the continuous working time of the first heating element 31 to be a first preset time length; the first preset time length 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 product 1 from the first temperature to the second temperature in the first time period, to reduce the temperature of the aerosol generating substrate 11 in the aerosol generating product 1 from the second temperature to the third temperature in the second time period, to maintain the aerosol generating substrate 11 in the aerosol generating product 1 at the third temperature in the third time period, and to stop heating at the end of the third time period.

[0128] The first preset time length of the first heating element 31 also includes a fourth time period, which is located between the first time period and the second time period. During the fourth time period, the aerosol generating substrate 11 in the aerosol generating article 1 is maintained at the second temperature.

[0129] The first time period is 5s-7s, the second time period is 3s-5s, the third time period is 22s-25s, and the fourth time period is 3s-4s. The first temperature is 20-30°C, the second temperature is 300-350°C, and the third temperature is 220-280°C; optionally, 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.

[0130] In one embodiment, the controller 33 controls the continuous working time of the second heating element 31, the third heating element 31, and the fourth heating element 31 except the first heating element 31 to be the first preset time; the first preset time of the second heating element 31, the third heating element 31, and the fourth heating element 31 except the first heating element 31 includes a fifth period and a sixth period; the controller 33 controls the heating element 31 to raise the temperature of the aerosol generating substrate 11 in the aerosol generating article 1 from the first temperature to the third temperature in the fifth period, to maintain the aerosol generating substrate 11 in the aerosol generating article 1 at the third temperature in the sixth period, and to stop heating at the end of the sixth period. The first period is 2s-5s, and the second period is 25s-28s.

[0131] The aerosol generating substrate 11 in the first aerosol generating product 1 is heated to a second temperature higher than the temperature (third temperature) at which the aerosol is released by the first heating element 31 within the first time period, which is conducive to the aerosol generating substrate 11 to quickly release the aerosol, so that when the user inhales the aerosol generating device, the aerosol can be inhaled in the shortest possible time, thereby improving the user's experience. It can be understood that since the next heating element 31 starts to preheat the next aerosol generating product 1 when the heating of a 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 up the aerosol generating substrate 11 in the corresponding second aerosol generating product 1, the third aerosol generating product 1, and the fourth aerosol generating product 1 to the second temperature and then cool down to the third temperature, and can directly heat up to the third temperature. As the heating of the heating element 31 approaches the end, most of the aerosol generating matrix 11 in the corresponding aerosol generating product 1 is consumed, and 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, so as to ensure the consistency of the taste.

[0132] It is understandable that after the controller 33 controls one heating element 31 to work for the second preset time, it controls the next heating element 31 to start working. At this time, the next heating element 31 corresponds to the aerosol generating product 1 that has not been heated. That is, after the controller 33 detects that the aerosol generating substrate 11 in the aerosol generating product 1 has been heated for the first preset time, the controller 33 no longer controls the corresponding heating element 31 to work, so as to avoid the heating element 31 from burning dry and wasting electric energy. The number of the mounting portion 320, the heating element 31 and the aerosol generating product 1 is set correspondingly and designed according to the needs.

[0133] See also Fig.18 and Fig.19 , Fig.18 This is a partial structural diagram of the second embodiment of the atomizer host provided by this application. Fig.19 It is a partial cross-sectional schematic diagram of the second embodiment of the atomizer host provided by the present application.

[0134] In the second embodiment of the atomizer main unit 3, the structure of the atomizer 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, except that the structure of the heating element 31 and the positional relationship between the heating element 31 and the mounting portion 320 are different. The aerosol generating product 1 provided on the atomizer main unit 3 in the second embodiment can be Figure 5-9 An aerosol-generating article 1 is shown.

[0135] 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.

[0136] Based on the working mode of the controller 33 controlling the heating element 31, an aerosol generating method is provided. Fig. 20 , Fig. 20 It is a schematic diagram of a process of an aerosol generation method provided in the present application.

[0137] The steps of the aerosol generation method are as follows:

[0138] S01: Provide multiple aerosol generating articles and multiple heating elements.

[0139] Specifically, the aerosol generating products 1 and the heating elements 31 are arranged correspondingly; that is, the number of the aerosol generating products 1 is the same as the number of the heating elements 31 , and one heating element 31 heats one aerosol generating product 1 .

[0140] 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 .

[0141] The heating element 31 includes a resistance wire, which heats the encapsulation layer 12 so that the encapsulation layer 12 bakes the aerosol generating substrate 11 to generate aerosol; that is, the heating element 31 heats the encapsulation layer 12 so that the encapsulation layer 12 bakes the aerosol generating substrate 11 to generate aerosol. Or the heating element 31 includes an electromagnetic coil, and the electromagnetic coil and the encapsulation layer 12 (the encapsulation layer 12 is a heating layer) generate heat under the magnetic field of the electromagnetic coil, and the encapsulation layer 12 heats the aerosol generating substrate 11 to form an aerosol. In order to improve the heating efficiency of the heating element 31, the encapsulation layer 12 is arranged in a close relationship with the heating element 31.

[0142] S02: The controller controls the multiple heating elements to work in sequence.

[0143] Specifically, the controller 33 controls the plurality of heating elements 31 to sequentially heat the aerosol generating product 1. The plurality of heating elements 31 all work for a first preset time, and when the heating element 31 works for a second preset time, the controller 33 is further used to control the next heating element 31 to start working; the second preset time is shorter than the first preset time.

[0144] In this method, the method in which the controller 33 controls the heating element 31 can realize the functions of the controller 33 introduced above, which will not be described in detail here.

[0146] The gas communication component 2 includes a top cover 21 and a bottom cover 22. The top cover 21 is formed with a first cavity 211 and a second cavity 212 that are interconnected; an air outlet 231 is provided on the cavity wall of the second cavity 212 for the user to inhale. The bottom cover 22 includes a bottom cover body 221 and a protrusion 222 provided on the bottom cover body 221. The bottom cover body 221 is provided in the first cavity 211, and the protrusion 222 is provided in the second cavity 212; the protrusion 222 is provided with an air outlet channel 23.

[0147] The bottom cover 22 is used to cooperate with the end of the atomizer mainframe 3 provided with the aerosol generating product 1 to form an atomizing chamber 24, that is, the gas communication component 2 cooperates with the atomizer mainframe 3 to form the atomizing chamber 24; the aerosol generating product 1 is provided at the end of the atomizer mainframe 3 close to the gas communication component 2, and the aerosol generating product 1 is located in the atomizing chamber 24. Specifically, the bottom cover body 221 includes a first surface 2211 and a second surface 2212 arranged opposite to the first surface 2211, the protrusion 222 is arranged on the first surface 2211, and the second surface 2212 has a recess 2213, and the recess 2213 cooperates with the end of the atomizer mainframe 3 provided with the aerosol generating product 1 to form the atomizing chamber 24.

[0148] 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 bottom cover 22 and the top cover 21 define an air inlet channel 25, and the air inlet channel 25 connects the atomizing chamber 24 with the outside atmosphere, and the air outlet channel 23 connects the atomizing chamber 24 with 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, the outside cold air continuously flows into the air inlet channel 25, and the air flow brings the heat in the air inlet channel 25 during the flow to the atomizing chamber 24, thereby cooling the top cover 21, that is, cooling the outer wall of the nozzle assembly 2, and improving the cooling efficiency to prevent the user from being scalded by high temperature.

[0149] 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 nozzle assembly 2, the air inlet 251 is arranged 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 arranged on the top wall of the second cavity 212. The top surface of the protrusion 222 abuts against the top wall of the second cavity 212, the annular side wall of the second cavity 212 is spaced from the side surface of the protrusion 222, and a shielding sheet 26 is arranged 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; the 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 sheet 26 may be disposed on the side surface of the protrusion 222 , or may be disposed on the annular side wall of the second cavity 212 .

Specifically, the shielding sheet 26 is disposed on both sides of the protrusion 222; since the bottom cover body 221 and the top wall of the first cavity 211 are spaced apart, one end of the shielding sheet 26 extends to the bottom cover body 221, so that part of the shielding sheet 26 abuts against the inner wall surface of the first cavity 211; the other end of the shielding sheet 26 extends toward the top wall close to the second cavity 212, so as to divide 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.

The size of the notch 263 is designed according to the requirements of the suction resistance and the air intake.

[0152] In another embodiment, the shielding sheet 26 is in contact with the top wall of the second cavity 212 at one end thereof, and a through hole is provided at one end thereof to connect the first space 261 with the second space 262. The size of the through hole is designed according to the requirements of the suction resistance and the air intake.

[0153] In another embodiment, there is a gap between the end of the shielding sheet 26 close to the second cavity 212 and the top wall of the second cavity 212, so that the first space 261 is connected to the second space 262. The distance (gap) between the end of the shielding sheet 26 close to the second cavity 212 and the top wall of the second cavity 212 is 4 mm-7 mm, and the size of the gap is designed according to the requirements of the suction resistance and the air intake.

[0154] 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 squeeze the aerosol generating product 1 so that the aerosol generating product 1 is closely fitted with the heating element 31 in the atomizing host 3. A mounting hole 2214 is disposed on the bottom wall of the recess 2213 of the bottom cover body 221, and the mounting hole 2214 is used to mount the elastic member 223; that is, the structural dimensions and arrangement of the mounting hole 2214 are matched with the structural dimensions and arrangement of the elastic member 223.

[0155] The elastic member 223 has a recess 2231 on its surface close to 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 a notch, so that the aerosol in the recess 2231 enters the atomization chamber 24.

[0156] A plurality of elastic members 223 are disposed on the bottom cover body 221, one elastic member 223 is disposed 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. A first connecting hole 2232 is disposed on the elastic member 223 farthest from the protrusion 222, which is used to connect the air inlet channel 25 with the atomizing chamber 24; a second connecting hole 2233 is disposed on the elastic member 223 disposed corresponding to the protrusion 222, which is used to connect the atomizing chamber 24 with the air outlet channel 23.

[0157] 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, and 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.

[0158] See also Fig.26 , Fig.26 It is a schematic diagram of the gas flow of the gas communication component provided in this application.

[0159] After the outside atmosphere enters the gas connecting component through the air inlet hole 251, it enters the second space 262 from the first space 261 through the notch 263 on the shielding sheet 26 along the extension direction of the protrusion 222, then enters the gap between the bottom cover body 221 and the top wall of the first cavity 211, and then enters the atomization cavity 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.

[0160] 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 that deviates 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 that deviates from the adjacent elastic member 223.

[0161] 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 the present application; for the structures of the first embodiment and the third embodiment of the aerosol generating product 1 provided in the present application, the present application also provides an atomizer host 3 with another structure.

The controller 33 and the power supply 34 are arranged in a cavity formed by the housing 30, and the controller 33 controls the power supply 34 to supply power to the heating element 31. An installation groove 35 is formed at one end of the housing 30, and the installation groove 35 is used to accommodate the heating element 31 and the aerosol generating product 1. Specifically, the heating element 31 is arranged on the side wall of the installation groove 35, and the aerosol generating product 1 is arranged in the space formed by the heating element 31.

[0164] The gas communication component 2 includes a cooling element 28 and a filter element 27. The cooling element 28 is disposed 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 disposed 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 an 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 and then transmitted to the user's mouth through the suction filter element 27, so as to avoid the aerosol temperature being too high and scalding the user. Among them, the material of the cooling element 28 is a heat-resistant dense material; for example, the material of the cooling element 28 can be plastic or ceramic.

[0165] The filter 27 is installed at one end of the cooling member 28 away from the installation slot 35, and the filter 27 covers the end of the communication hole away from the installation slot 35, so that the aerosol in the communication hole is transmitted to the user's mouth through the filter 27. The filter 27 is used to filter out the aerosol generating matrix 11 that enters the communication hole along with the airflow of the aerosol. The material of the filter 27 can be a porous material; for example, a cotton core.
