Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] An aerosol generating device is a device that enables an aerosol generating matrix to produce aerosols for a user to inhale when heated without combustion. The device includes a housing, a heating element, a power supply providing electrical power to the heating element, and a display screen for displaying at least some parameters of the aerosol generating device. The display screen needs to be located inside the housing, and a seal needs to be provided between the display screen and the housing to prevent liquids or dust from entering the display screen or its surface. A tubular housing is not conducive to establishing a seal between the display screen and the housing because, during the process of assembling the sealing layer into the housing from one end along with the display screen, the sealing layer may warp or shift due to being scratched by the display screen cover on the housing, thus affecting the sealing effect. Therefore, known housings at least include a first part and a second part, which, when joined together, enclose the display screen within the housing.

[0003] However, setting the shell to be assembled from multiple scattered parts not only results in poor shell consistency and affects the aesthetics of the aerosol generating device, but also increases the assembly process of the aerosol generating device and affects its production efficiency. Utility Model Content

[0004] The purpose of this application is to provide an aerosol generating device that can solve the problem of seal warping or displacement during the process of assembling interactive components from one end of a tubular housing into the housing.

[0005] At least one embodiment of this application provides an aerosol generating apparatus, the aerosol generating apparatus comprising:

[0006] A tubular shell with a transverse through hole, and the shell having a first end and a second end arranged opposite to each other in the longitudinal direction;

[0007] A light-transmitting cover, comprising a first portion located inside the housing and a second portion at least partially located within the through-hole; and

[0008] The interactive components include an elastic element, a display screen, and a frame-shaped seal disposed on the outer edge region of the display screen;

[0009] The interactive component is configured to be fitted into the housing from the first end, and the elastic member elastically deforms during the process of fitting the interactive component into the housing, causing the display screen to move inward to prevent the cover from scratching the seal, and when the display screen corresponds to the second part, the elastic member provides elastic force to seal the connection between the display screen and the first part.

[0010] As an example, the interactive component also includes a first bracket for holding the display screen, the elastic element supporting the first bracket, the first bracket having a third end disposed toward the first end and a fourth end disposed toward the second end in the longitudinal direction;

[0011] During the process of assembling the interactive component into the housing, the deformation of the elastic element causes the fourth end to sink inward first, and then the sinking degree decreases, causing the first bracket to tilt first, and then return to being parallel to the longitudinal direction when the display screen is set to correspond to the second part.

[0012] As an example, the elastic element is disposed corresponding to the central region of the first bracket; or

[0013] The third end is provided with a pivot, allowing the first bracket to rotate relative to the housing. The elastic element supports the first bracket at or near the fourth end; or

[0014] The elastic element has at least two parts, at least one of the elastic elements is located at or near the third end of the first bracket, and at least one of the elastic elements is located at or near the fourth end of the first bracket.

[0015] As an example, the fourth end has a first guide portion that is tilted;

[0016] During the process of assembling the interactive component into the housing, the first guide portion is used to guide the first bracket to slide past the edge of the first portion to the inside of the first portion.

[0017] As an example, the first bracket includes a receiving cavity and a sidewall defining a portion of the boundary of the receiving cavity, the display screen being received in the receiving cavity, and the sidewall including a protrusion and a recess;

[0018] The first part includes a base and a longitudinally extending ridge disposed on the base. The first guide portion is part of the sidewall and is located on the side of the ridge away from the recess, so as to guide the ridge to slide to abut against the ridge during the process of assembling the interactive component into the housing. When the ridge abuts against the ridge, the elastic member deforms to tilt the first bracket, thereby causing the seal to be spaced apart from the base.

[0019] As an example, the ridge is configured to slide along the protrusion to abut against the recess during the assembly of the interactive component into the housing, wherein the first bracket is parallel to the longitudinal direction and the seal abuts against the base when the ridge primarily abuts against the recess of the protrusion and the recess.

[0020] As an example, the sidewall also includes a third guide portion that connects the protrusion and the recess and is disposed at an angle, the third guide portion being configured to guide the convex edge toward the end disposed at the second end to slide from the protrusion to the recess during the process of assembling the interactive component into the housing.

[0021] As an example, the end of the protruding ridge facing the first end has an inclined second guide portion, which slides along the first guide portion during the assembly of the interactive component into the housing to guide the protruding ridge to slide into contact with the protrusion; and / or

[0022] The end of the protruding ridge facing the second end has a fourth guide portion that is inclined. The fourth guide portion slides along the third guide portion during the process of the interactive component being assembled into the housing to guide the protruding ridge to slide away from the protrusion and slide to abut against the recess.

[0023] As an example, a fifth guide portion is provided on the inner side of the end of the base facing the first end, and the protruding ridge is spaced apart from the fifth guide portion; and / or

[0024] A sixth guide portion is provided on the inner side of the end of the base facing the second end, and the protruding ridge is spaced apart from the fifth guide portion.

[0025] As an example, the aerosol generating device also includes a power source disposed inside the housing;

[0026] The interactive component also includes a circuit board electrically connected to the power supply and a micro switch disposed on the circuit board, and the display screen is electrically connected to the circuit board;

[0027] The micro switch is located inside the first bracket, and the second part is in clearance fit with the housing in the through hole, so that the second part can move slightly along the central axis of the through hole. The first bracket is configured to trigger the micro switch when the cover is pressed.

[0028] As an example, one end of the elastic element abuts against the circuit board, and the other end abuts against the first bracket.

[0029] As an example, the interactive component also includes an elastic pad disposed between the micro switch and the first bracket.

[0030] As an example, the aerosol generating apparatus further includes a second support and a heating assembly for heating the aerosol generating matrix to generate aerosols;

[0031] Both the heating component and the interaction component are held on the second bracket, so that the three are assembled into a whole inside the housing.

[0032] As an example, the aerosol generating device further includes an end cap assembly connected to a first end of the housing to shield the second support.

[0033] The aerosol generating device provided in the above embodiments includes a tubular housing, a light-transmitting shielding cover, and an interactive component. At least a portion of the second part of the shielding cover is disposed in a transverse through-hole on the housing, while the first part of the shielding cover is located inside the housing. The interactive component can be assembled into the housing from its first end. During assembly, the elastic element of the interactive component undergoes elastic deformation, causing the display screen to move inward to prevent the shielding cover from scratching the sealing element. Furthermore, when the display screen is positioned corresponding to the second part, the elastic element provides elastic force to ensure a tight seal between the first part and the display screen. Therefore, before assembling the interactive component into the housing, the housing is already a tubular structure, and the interactive component, during its insertion into the tubular housing, can prevent the shielding cover from scratching the first part. This reduces the assembly process of the aerosol generating device, improves its production efficiency, and ensures good sealing between the display screen and the first part after assembly.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0052] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements. When an element is referred to as being "connected to" another element, it can be directly connected to the other element, or there may be one or more intervening elements.

[0053] Please refer to Figures 1-3This application provides an embodiment of an aerosol generating device 100, which includes a tubular housing 1, a light-transmitting cover 2, and an interactive component with a display screen 31. The interactive component 3 is disposed inside the housing 1 and corresponding to the cover 2, such that at least a portion of the cover 2 is located outside the display screen 31. Light signals on the display screen 31 can be transmitted through the cover 2, allowing the user to identify the information displayed on the display screen 31 by observing the cover 2.

[0054] The tubular housing 1 has a first end 11 and a second end 12 arranged opposite each other in the longitudinal direction, and the wall between the first end 11 and the second end 12 encloses the tubular structure. The tubular structure can be circular, rectangular, elliptical, polygonal or other shapes, without specific limitations. At least one of the first end 11 and the second end 12 is open, so that it can be entered by the interaction component 3.

[0055] A through hole 13 is provided on the wall of the housing 1, such that the through hole 13 is arranged laterally and its central axis is perpendicular to the longitudinal direction. In such a case... Figure 3 In the illustrated embodiment, the through hole 13 is spaced apart from both the first end 11 and the second end 12. The distance between the through hole 13 and the first end 11 may be smaller than the distance between the through hole 13 and the second end 12, but is not limited thereto.

[0056] The housing 1 can be a metal housing, a plastic housing, or a composite housing. The housing 1 can be formed by a single molding process. The housing 1 can also be a pre-formed product or standard part assembled from multiple components before being assembled with the interacting components.

[0057] The cover 2 includes a first portion 21 located inside the housing 1 and a second portion 22 located at least partially in the through hole 13. In some embodiments, the cross-sectional area of ​​the first portion 21 is larger than the cross-sectional area of ​​the second portion 22, such that the first portion 21 cannot pass through the through hole 13, thereby allowing the cover 2 to remain connected to the housing 1 after the housing 1 is combined with the interaction component 3, helping to prevent the cover 2 from detaching from the housing 1. The first portion 21 and the second portion 22 can be integrally formed.

[0058] The interactive component 3 also includes a frame-shaped seal 32 disposed on the outer edge region of the display screen 31. The display screen 31 primarily displays information through its central area. The frame-shaped seal 32 is disposed on the edge region of the display screen 31 and surrounds the central region of the display screen 31 to prevent the seal 32 from obstructing the information displayed on the display screen 31. The seal 32 may include foam or silicone. The seal 32 may be a one-piece molded frame structure. The seal 32 may be a frame structure formed by splicing multiple sealing components. The seal 32 can be fixed to the outer surface of the display screen 31 by adhesive. Of course, the seal 32 can also be connected to the display screen 31 in other ways. The display screen 32 can be any suitable screen; for example, the display screen 31 can be an LCD screen.

[0059] The interactive component 3 also includes an elastic element 33, which is configured to be fitted into the housing 1 from the first end 11. The elastic element 33 is configured to elastically deform during the fitting of the interactive component 3 into the housing 1, causing the display screen 31 to move inward to prevent the cover 2 from scratching the seal 33. When the display screen 31 corresponds to the second part 22, it provides elasticity so that the seal 33 seals the connection between the display screen 31 and the first part 21.

[0060] The first part 21 of the cover 2 is located inside the housing 1, such that at least a portion of the inner surface of the first part 21 and at least a portion of the inner surface of the housing 1 form a step-like structure. Therefore, during the process of assembling the interactive component 3 into the housing 1 so that the display screen 31 is aligned with the second part 22 of the cover 2, the interactive component 3 needs to "climb" up this step. During this process, the elastic element 33 has elastic deformation, so that the display screen 31 and the sealing element 32 provided on the display screen 31 can both move inward to avoid the cover 2 from scratching the sealing element 32, so that the sealing element 32 does not warp, shift and / or twist in the longitudinal direction. Thus, when the display screen 31 is aligned with the second part 22, the sealing element 32 can provide a good seal between the display screen 31 and the first part 21.

[0061] It should be noted that the "preventing the cover 2 from scratching the seal 32" may include: (1) during the process of assembling the interactive component 3 into the housing 1, before the second part 22 of the cover 2 corresponding to the display screen 31 is set, there is no contact between the cover 2 and the seal 32; or (2) during the process of assembling the interactive component 3 into the housing 1, before the second part 22 of the cover 2 corresponding to the display screen 31 is set, there may be contact between the cover 2 and the seal 32, but the resistance of the cover 2 to the seal 32 is small, so that the seal 32 is not enough to curl, shift and / or twist in the longitudinal direction, for example, the resistance of the cover 2 to the seal 32 is less than the adhesive force between the display screen 31 and the seal 32.

[0062] Furthermore, "the display screen 31 is set to correspond to the second part 22" mainly refers to the central area of ​​the display screen 31 being set to correspond to the second part 22, so that the information displayed on the display screen 31 is displayed through the second part 22. Figure 1 and Figure 8 In the embodiment shown, the first part 21 and the second part 22 are stacked horizontally, so that the light emitted by the display screen 31 can pass through the first part 21 and the second part 22 in sequence and be emitted.

[0063] In some embodiments, reference may be made to Figures 2-7 The interactive component 3 also includes a first bracket 34 for holding the display screen 31. An elastic element 33 supports the first bracket 34. The elastic element 33 acts on the display screen 31 by acting on the first bracket 34, which can prevent the display screen 31 from being damaged due to uneven force.

[0064] More specifically, the first support 34 may include a bottom wall and a side wall 341. The bottom wall is located inside the display screen 31 and is used to support the display screen 31; the elastic member 33 can abut against the bottom wall. The side wall 341 is connected to the bottom wall and is disposed on the side of the display screen 31, enabling the display screen 31 to be positioned. The first support 34 also has a receiving cavity 342, in which at least a portion of the display screen 31 is held; both the bottom wall and the side wall 341 define a portion of the boundary of the receiving cavity 342.

[0065] At least a portion of the seal 32 is located outside the receiving cavity 342 to provide a seal between the cover 2 and the display screen 31.

[0066] In some embodiments (not shown), during the process of assembling the interactive component 3 into the housing 1, the elastic element 33 undergoes elastic deformation, causing the first bracket 34 to sink or translate inward as a whole, thereby increasing the lateral distance between the first bracket 34, the display screen 31, the sealing element 32 and the cover 2, and preventing the cover 2 from scratching the sealing element 32.

[0067] Alternatively, in some embodiments, reference may be made to Figure 6The first bracket 34 has a third end 343 facing the first end 11 and a fourth end 344 facing the second end 12 in the longitudinal direction. During the process of assembling the interactive component 3 into the housing 1, the elastic element 33 undergoes elastic deformation, causing the fourth end 344 on the first bracket 34 to sink inward first, and / or the third end 343 on the first bracket 34 to tilt outward, causing the first bracket 34 to tilt. Therefore, the first bracket 34 can more easily "climb" the aforementioned step, preventing the cover 2 from scratching the seal 32. Then, the sinking degree of the fourth end 344 and / or the tilting degree of the third end 343 on the first bracket 34 decreases, and when the display screen 31 corresponds to the second part 22, the first bracket 34 returns to being parallel to the longitudinal direction, so that the seal 32 can be evenly pressed against the cover 2.

[0068] Based on this, as a typical example (not shown), the elastic element is set in the central area of ​​the first bracket, so that the elastic element supports the central area of ​​the first bracket, allowing the third and fourth ends of the first bracket to swing laterally, thereby allowing the first bracket to tilt.

[0069] As another typical example (not shown), the third end is provided with a pivot, allowing the first bracket to rotate relative to the housing. Specifically, the first bracket can rotate around the central axis of the pivot. The elastic element supports the first bracket at or near the fourth end, allowing the fourth end to sink inward and enabling the first bracket to tilt. When the fourth end sinks or rises, the position of the third end can remain unchanged.

[0070] As another typical example, see [reference] Figure 5 and Figure 6 The elastic element 33 has at least two parts, with at least one elastic element 33 supporting the first bracket 34 at or near the third end 343, and at least one elastic element 33 supporting the first bracket 34 at or near the fourth end 344. This allows the third end 343 and the fourth end 344 of the first bracket 34 to swing laterally, thereby enabling the first bracket 34 to tilt.

[0071] Two of the multiple elastic elements 33 are defined as the first elastic element and the second elastic element. The first elastic element 331 supports the first bracket 34 at or near the third end 343, and the second elastic element 332 supports the first bracket 34 at or near the fourth end 344. When the fourth end 334 sinks, the first elastic element 331 and the second elastic element 332 can have opposite deformation directions.

[0072] The elastic element 33 may include a spring arm, a silicone product, a spring, or a torsion spring, and is not limited thereto.

[0073] In some embodiments, reference may be made to Figure 6 and Figure 7 The fourth end 334 has a first guide portion 3411 that is inclined. During the process of assembling the interactive component 3 into the housing 1, the first guide portion 3411 is used to guide the first bracket 34 to slide over the edge of the first part 21 to the inside of the first part 21. In other words, the first guide portion 3411 is used to guide the first bracket 34 to "climb" the aforementioned step, so that the first bracket 34 can move more easily to the inside of the cover 2.

[0074] The first guide portion 3411 may include multiple inclined surfaces connected in sequence, and the different inclined surfaces may have different slopes or shapes. The first guide portion 3411 may include only one inclined surface. It should be noted that the inclined surface may include an inclined plane or a curved surface.

[0075] In some embodiments, reference may be made to Figure 4 , Figure 6 and Figure 7 The sidewall 341 of the first support 34 includes a protrusion 3412 and a recess 3413, such that the outer end of the first support 34 is a non-flush structure. The first guide portion 3411 can be a component of the sidewall 341, and the first guide portion 3411 is located on the side of the protrusion 3412 opposite to the recess 3413.

[0076] The first part 21 includes a base 211 and a longitudinally extending ridge 212 disposed on the base 211. During the assembly of the interactive component 3 into the housing 1, the ridge 212 can slide along the outer end of the sidewall 341. When the display screen 31 is positioned corresponding to the second part 22, the sidewall 341 supports the ridge 212. The base 211 can be positioned corresponding to the seal 32. When the display screen 31 is positioned corresponding to the second part 22, the seal 32 can provide a seal between the display screen 31 and the base 211.

[0077] During the assembly of the interactive component 3 into the housing 1, the first guide portion 3411 guides the protrusion 212 to slide until it abuts against the protrusion 3412. When the protrusion 212 abuts against the protrusion 3412, the elastic member 33 deforms, causing the first bracket 34 to tilt, thereby allowing the seal 32 to be spaced apart from the base. This prevents the base 211 from scratching the seal 32 during the abutment of the protrusion 212 against the protrusion 3412.

[0078] As the protrusion 212 slides along the first guide portion 3411, the fourth end 344 sinks inward, causing the first support 34 to tilt. During the process of the protrusion sliding along the first guide portion 3411, the inward sinking degree of the fourth end 344 gradually increases, and the tilting degree of the first support 34 gradually increases accordingly.

[0079] In some embodiments, the protrusion 212 is configured to slide along the protrusion 3412 to abut against the recess 3413 during the assembly of the interaction component 3 into the housing 1. When the protrusion 212 primarily abuts against the recess 3413 in both the protrusion 3412 and the recess 3413 (see reference...), Figure 4 The first bracket 34 is parallel to the longitudinal direction, and the seal 32 abuts against the base 211.

[0080] In some embodiments, reference may be made to Figure 4 , Figure 6 and Figure 7 The sidewall 341 also includes a third guide portion 3414 that connects the protrusion 3412 and the recess 3413 and is inclined. The third guide portion 3414 is configured to guide the end of the protrusion 212 facing the second end 12 to slide from the protrusion 3412 to the recess 3413 during the process of assembling the interactive component 3 into the housing 1. This prevents the protrusion 212 from abruptly falling from the protrusion 3412 to the recess 3413, allowing the end of the protrusion 212 facing the second end 12 to smoothly transition from contact with the protrusion 3412 to contact with the recess 3413.

[0081] As the convex ridge 212 slides along the convex portion 3412, the inward sinking of the fourth end 344 gradually increases, and the inclination of the first bracket 34 gradually increases accordingly. The lateral distance between the sealing element 32 located at or near the third end 343 and the base 211 can gradually decrease.

[0082] As the protruding rib 212 slides along the third guide portion 3414, the fourth end 344 remains in a downward-sloping inward state, while the first support 34 remains in an inclined state. During the sliding process of the protruding rib 212 along the third guide portion 3414, the downward slope of the fourth end 344 gradually decreases, and the inclination of the first support 34 decreases accordingly. Until the protruding rib 212 slides away from the third guide portion 3414 and abuts against the recess 3413, the first support 34 returns to being parallel to the longitudinal direction.

[0083] Meanwhile, as the ridge 212 slides along the third guide portion 3414, the lateral distance between the seal 32 located at or near the third end 343 and the base 211 can gradually increase, thereby preventing the end of the base 211 located towards the first end 11 from scraping the seal 32.

[0084] In some embodiments, reference may be made to Figure 8 The protruding ridge 212 has an inclined second guide portion 2121 on the end facing the first end 11. The second guide portion 2121 slides along the first guide portion 3411 during the process of assembling the interactive component 3 into the housing 1, so as to guide the protruding ridge 212 to slide to abut against the protrusion 3412.

[0085] In some embodiments, reference may be made to Figure 8 The end of the protruding ridge 212 facing the second end 12 has an inclined fourth guide portion 2122. During the process of assembling the interactive component 3 into the housing 1, the fourth guide portion 2122 slides along the third guide portion 3414 to guide the protruding ridge 212 to slide away from the protrusion 3412 and slide to abut against the recess 3413.

[0086] In some embodiments, reference may be made to Figure 8 A fifth guide portion 2111 is provided on the inner side of the end of the base 211 facing the first end 11 to prevent the end of the base 211 facing the first end 11 from scratching the seal 32. The protruding ridge 212 is spaced apart from the fifth guide portion 2111. The end of the base 211 facing the first end 11 can interfere with the housing 1 inside the housing 1, thereby preventing the first portion 21 from passing through the through hole 13.

[0087] In some embodiments, reference may be made to Figure 8 A sixth guide portion 2112 is provided on the inner side of the end of the base 211 facing the second end 12 to prevent the end of the base 211 facing the second end 12 from scratching the seal 32. The protruding ridge 212 and the sixth guide portion 2112 are spaced apart. The end of the base 211 facing the second end 12 can interfere with the housing 1 inside the housing 1, thereby preventing the first portion 21 from passing through the through hole 13.

[0088] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 also includes a power supply 5, which is located inside the housing 1 to provide electrical power to the display screen 31.

[0089] The interactive component 3 also includes a circuit board 36 electrically connected to the power supply 5 and a micro switch 35 disposed on the circuit board 36. The micro switch 35 is located inside the first bracket 34, and the second part 22 is clearance-fitted with the housing 1 in the through hole 13, so that the second part 22 can move slightly along the central axis of the through hole 13. The first bracket 34 is configured to trigger the micro switch 35 when the cover 2 is pressed.

[0090] The power supply 35 may include any suitable battery, such as a lithium battery. The display screen 31 is electrically connected to the circuit board 36, and in turn, the display screen 31 is electrically connected to the power supply 5.

[0091] Further, you can refer to Figure 5 One end of the elastic member 33 abuts against the circuit board 36, and the other end abuts against the first bracket 34.

[0092] Therefore, when the second part 22 of the cover 2 is pressed, the cover 2 moves inward laterally, causing the first bracket 34 to move inward, and the bottom wall of the first bracket 34 triggers the micro switch 35. When the pressing force applied to the second part 22 is removed, the elastic element 33 provides elastic force, driving the first bracket 34 to move outward, and the first bracket 34 drives the cover 2 to move outward laterally, the second part 22 resets, and the triggering of the micro switch 35 is released.

[0093] In some embodiments, reference may be made to Figure 5 and Figure 6 The interactive component 3 also includes an elastic pad 37, which is disposed between the micro switch 35 and the first bracket 34, so that the contact between the first bracket 34 and the micro switch 35 can be a soft contact, which is beneficial to protect the micro switch 35. Furthermore, when the aerosol generating device 100 slides or falls, the elastic pad 37 can play a buffering role to prevent the micro switch 35 from being accidentally triggered.

[0094] In some embodiments, reference may be made to Figure 2 The aerosol generating apparatus 100 also includes a heating component 6, which is used to heat the aerosol generating matrix to generate aerosols.

[0095] In some embodiments, the aerosol-generating matrix includes a liquid matrix. The liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may comprise, but is not limited to, water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. The vitamin mixture may be a mixture containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited to this.

[0096] When the aerosol generating matrix includes a liquid matrix, the aerosol generating apparatus 100 may further include a container for storing the liquid matrix, with the heating assembly 6 in fluid communication with the container to atomize the liquid matrix into an aerosol through heating. Based on this, the heating assembly 6 may include a liquid-absorbing element and a heating element. The liquid-absorbing element is used to adsorb the liquid matrix and is capable of transferring at least a portion of the adsorbed liquid matrix to the heating range of the heating element, so that the liquid matrix is ​​heated and atomized by the heating element. The heating element may be disposed on the liquid-absorbing element.

[0097] In some embodiments, the aerosol-generating matrix includes a solid matrix. The solid matrix may include tobacco-containing material containing volatile tobacco flavor compounds that are released from the matrix upon heating. Alternatively, the solid matrix may include non-tobacco materials. The solid matrix may include one or more of, for example, powders, granules, pellets, flakes, strips, bands, or sheets, containing one or more of herbaceous plant leaves, tobacco leaves, tobacco vein fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, and expanded tobacco.

[0098] When the aerosol generating matrix includes a solid matrix, the heating component 6 may include an internal heating component, an external heating component, and / or an air heating component.

[0099] As used herein, the term "external heating assembly" refers to a heating assembly positioned outside the solid matrix when the solid matrix is ​​assembled in the aerosol generating apparatus 100. As used herein, the term "internal heating assembly" refers to a heating assembly positioned at least partially within the solid matrix when the solid matrix is ​​assembled in the aerosol generating apparatus 100. As used herein, the term "air heating assembly" refers to a heating assembly used to heat air in an air intake channel that enters the solid matrix through the air intake channel. The air heating assembly heats the air flowing through the air intake channel into high-temperature air, which then enters the solid matrix and exchanges heat with the solid matrix, thereby heating and baking the solid matrix.

[0100] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 also includes a second support 4, on which the heating component 6 and the interaction component 3 are both held, so that the heating component 6, the interaction component 3 and the second support 4 form a whole. This whole can then be assembled into the housing 1, which helps to further reduce the assembly process of the aerosol generating device 100 and improve the production efficiency of the aerosol generating device 100.

[0101] More specifically, the first bracket 34 can be fixed to the second bracket 4 by a snap-fit ​​connection, and the second bracket 4 can support the circuit board 36. The second bracket 4 may have a receiving cavity 41, in which a portion of the heating component 6 can be placed, and the aerosol generating matrix can also be placed in the receiving cavity 41.

[0102] In some embodiments, reference may be made to Figure 1 and Figure 2 The aerosol generating device 100 also includes an end cap assembly 7, which is connected to the first end 11 of the housing 1 to cover the second support 4.

[0103] Before the end cap assembly 7 is connected to the first end 11 of the housing 1, the second bracket 4 can cover the interaction component 3, thereby hiding the interaction component 3. After the end cap assembly 7 is connected to the first end 11 of the housing 1, the second bracket 4 can be covered by the end cap assembly 7, thereby hiding the second bracket 4.

[0104] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
