Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0047] In the field of aerosol generation technology, the structure of an aerosol generating device is usually provided with a containing chamber, which is used to contain an aerosol generating product, and then the aerosol generating product in the containing chamber is heated by a heating component to generate aerosol, which is then discharged along an air outlet channel. Whenever the aerosol generating product is used up, the used aerosol generating product needs to be taken out of the containing chamber and replaced with a new aerosol generating product before it can be used again. Therefore, it is inconvenient to replace the aerosol generating product, and the user experience is poor.

[0048] Based on the above problems, an aerosol generating device is provided in the embodiment of the present application. Figure 1-8 As shown, the aerosol generating device comprises a main body 1 and an assembly 2 .

[0049] The host 1 has a mounting position 10 and an air outlet channel 11, and the air outlet channel 11 is connected to the mounting position 10; the assembly part 2 is rotatably mounted on the mounting position 10; a plurality of accommodating cavities 20 are formed inside the assembly part 2, and the accommodating cavities 20 are used to accommodate aerosol generating products; the accommodating cavities 20 are provided with air outlets 21; the mounting position 10 is provided with a positioning portion 13, and the assembly part 2 is provided with a positioning structure 22; during the rotation of the assembly part 2 at the mounting position 10, each accommodating cavity 20 can be switched to a working state in turn, and in the working state, the air outlet 21 of the corresponding accommodating cavity 20 is connected to the air outlet channel 11, and the positioning portion 13 cooperates with the positioning structure 22 to limit the further rotation of the assembly part 2.

[0050] Among them, the host 1 is formed with an installation position 20 for installing the assembly part 2. In one embodiment, the installation part 20 can be a structure such as a groove, a notch, a cavity, etc. The installation part 20 is provided with a window, and the window and the air outlet of the air outlet channel 11 face different sides of the host 1 respectively. The different sides of the host 10 can refer to the top side, the front side, the left side, the right side, the rear side, and the bottom side. The assembly part 2 can be installed into the installation position through the window, and can also be removed or slid out from the installation position.

[0051] Among them, the accommodation cavity 20 is provided with a replacement opening for the aerosol generating article. In one embodiment, the fitting 2 can be slidably installed into or out of the installation position through the window of the installation position, exposing the replacement opening of the aerosol generating article outside the main body for the user to replace the aerosol generating article.

[0052] The fitting 2 located within the installation position 20 can rotate relative to the main body 1, and during the rotation, the switching of each accommodation cavity 20 on the fitting 2 can be achieved. The process of the fitting 2 rotating and switching is also the process in which each accommodation cavity 20 alternately enters the working state. In the embodiment of the present application, the working state refers to the corresponding accommodation cavity 20 being in the heated position, and the air outlet 21 corresponding to the accommodation cavity 20 is communicated with the air outlet passage 11, so that the aerosol generated by heating can be discharged outward along the air outlet 21 and the air outlet passage 11.

[0053] An air outlet passage 11 communicating with the installation position 10 is formed on the main body 1. Since the fitting 2 is rotatably installed in the installation position 10, through the communication relationship between the installation position 10 and the air outlet passage 11, each accommodation cavity 20 on the fitting 2 can be respectively communicated with the air outlet passage 11. To adapt to the air outlet passage 11, a mouthpiece portion can also be provided on the main body 1, and at least part of the air outlet passage 11 is formed by the hollow interior of the mouthpiece portion. The mouthpiece portion is integrally formed on the main body 1, or the mouthpiece portion can also be detachably connected to the main body 1.

[0054] In addition, the main body 1 in the embodiment of the present application can also be formed by splicing multiple components, and the splicing structure can be fixedly connected through the cooperation of snap fasteners, adhesives, and threaded fasteners. The corresponding assembly space can be provided inside the main body 1, and the assembly space is used to accommodate other components required for the aerosol generating device, including but not limited to a power supply component, a circuit board, etc. Interaction components such as a display, a touch button, and a charging port can also be provided outside the main body. The display can be used to display the usage status of the aerosol generating device; the touch button can be used to control the working state of the aerosol generating device, such as switch adjustment, heating power adjustment, etc.; the charging port can be used to charge the power supply component.

[0055] It is worth mentioning that, in the aerosol generating device according to the embodiments of the present application, the heating method for the aerosol is heat-not-burn, and the specific heating modes include two categories: aerobic heating and anaerobic heating. Among them, the difference between aerobic heating and anaerobic heating is that, when heating the aerosol generating article by aerobic heating, a corresponding air inlet channel needs to be provided, and during the heating process, air is mixed with the aerosol generating article, and the generated aerosol is also discharged along with the air; while for anaerobic heating, no air inlet channel is required, and the air flow does not pass through the aerosol generating article during the heating process. An air inlet channel can be provided outside the air outlet 21 of the accommodation chamber 20 to dilute the aerosol generated by heating, and the aerosol is discharged through the Bernoulli principle. Therefore, according to the difference in the specific heating type, a corresponding air inlet channel 12 can be selectively provided on the main body. When the air inlet channel 12 is provided, it is applicable to the aerobic heating mode, and when the air inlet channel is not provided or the air inlet channel is provided at the air outlet 21 of the accommodation chamber 20, it is applicable to the anaerobic heating mode. Of course, a trigger switch for the on / off of the air inlet channel can also be provided, and the air inlet channel is triggered to communicate with or disconnect from the outside through the trigger switch, so as to achieve the switching between aerobic heating and anaerobic heating.

[0056] In addition, aerobic heating requires mixing air with the aerosol generating article during the heating process. Therefore, an air inlet 23 also needs to be correspondingly provided in the accommodation chamber 20 of the fitting, and air is injected through the connection between the air inlet 23 and the air inlet channel 12. If it is the anaerobic heating mode, in addition to not providing an air inlet channel on the main body 1, it can also be achieved by not providing an air inlet for the accommodation chamber 20.

[0057] The fitting 2 is rotatably connected to the mounting position 10 on the main body 1. During the rotation process, the accommodation chamber 20 on the fitting 2 also changes its position accordingly. At least two mutually partitioned accommodation chambers 20 are provided on the fitting 2, and each accommodation chamber 20 can independently accommodate an aerosol generating article. By setting different types of aerosol generating articles, the generation of aerosols with different flavors can be achieved; and by providing multiple accommodation chambers 20, the available duration is longer after each replacement of the aerosol generating article. For the sake of uniform rotation, each accommodation chamber 20 can be symmetrically distributed about the rotation axis of the fitting 2.

[0058] The accommodation chamber 20 is provided with an air outlet 21 for discharging the aerosol; in addition, the air outlet 21 of the accommodation chamber 20 can also be used as a replacement port for the aerosol generating article, that is, the aerosol generating article can be placed into the accommodation chamber 20 through the air outlet 21 of the accommodation chamber 20.

[0059] In the embodiments of the present application, in order to ensure that when the accommodating cavity 20 switches to the working state, the air outlet 21 of the accommodating cavity 20 can be quickly and accurately aligned and communicated with the air outlet channel 11 on the main body 1, preventing problems such as aerosol leakage and insufficient heating caused by the misalignment between the air outlet 21 of the accommodating cavity 20 and the air outlet channel 11, a positioning portion 13 is provided on the installation position 10, and a positioning structure 22 is provided on the fitting 2. The positioning structure 22 and the positioning portion 13 have matching states corresponding to each accommodating cavity 20. In one matching state, the corresponding accommodating cavity 20 is in the working state. That is to say, in the embodiments of the present application, a positioning structure 22 and a positioning portion 13 are respectively provided on the rotatably connected fitting 2 and the main body 1, and the positioning structure 22 and the positioning portion 13 have a matching state with each other. When the positioning structure 22 and the positioning portion 13 match each other, the corresponding accommodating cavity 20 is in the working state; in other words, the user can judge whether the rotational switching between the fitting 2 and the main body 1 is in place through the matching state between the positioning structure 22 and the positioning portion 13. Therefore, the user can quickly achieve the rotational cooperation between the fitting 2 and the main body 1 during the operation process, so that the corresponding accommodating cavity 20 is in the working state, thereby improving the user experience.

[0060] In some alternative embodiments, please refer to Figure 2-6As shown, in order to achieve the matching state where the positioning structure 22 and the positioning portion 13 respectively correspond to each accommodation cavity 20, the number and position of the positioning structure 22 or the positioning portion 13 can be configured to be correspondingly provided with each accommodation cavity 20. The positioning portion 13 is provided on the inner wall of the installation position 10, and the positioning structure 22 is provided on the outer peripheral side of the fitting 2. When the fitting 2 rotates, it drives the positioning structure 22 to rotate along the inner wall of the installation position 10. When the positioning structure 22 is limited by the positioning portion 13, the rotation of the fitting 2 is restricted. That is to say, in order to make the cooperation state between the positioning structure 22 and the positioning portion 13 correspond to each accommodation cavity 20 respectively, in the embodiment of the present application, the positioning structure 22 located on the fitting 2, its number and setting position correspond to each accommodation cavity 20 one by one. Each accommodation cavity 20 corresponds to a positioning structure 22. The positioning structure 22 is provided on the outer peripheral side of the fitting 2 and cooperates with the positioning portion 13 provided on the inner wall of the installation position 10. Each positioning structure 22 can be individually matched with the positioning portion 13. When the fitting 2 rotates, it correspondingly drives the positioning structure 22 to rotate as well. When the positioning structure 22 is limited by the positioning portion 13 during the rotation process, that is, when the positioning structure 22 and the positioning portion 13 are in a matching state. It is worth mentioning that in the embodiment of the present application, a plurality of positioning structures 22 are provided on the fitting 2, and then the positioning portions 13 provided on the main body 1 are used to match with each positioning structure 22 one by one. In addition, it can also be that a plurality of positioning portions 13 are provided on the main body 1, and then the positioning structures 22 provided on the fitting 2 are used to match with each positioning portion 13 one by one. In the embodiment of the present application, the case where the number and position of the positioning structure 22 correspond to each accommodation cavity 20 one by one will be taken as an example for illustration. In fact, this solution can also be applied to the case where the number and position of the positioning portion 13 correspond to each accommodation cavity 20 one by one, and the embodiment of the present application does not limit it.

[0061] In some alternative embodiments, in order to achieve the limiting connection between the positioning structure 22 and the positioning portion 13, among the positioning portion 13 and the positioning structure 22, one of them can be set as the elastic protrusion 3, and the other is correspondingly set as the recess 4; when any positioning structure 22 is limited by the positioning portion 13, it corresponds to the elastic protrusion 3 being clamped in the recess 4. That is to say, in the embodiment of the present application, through the clamping cooperation between the elastic protrusion 3 and the recess 4, the limiting connection between the positioning portion 13 and the positioning structure 22 is achieved, and at the same time, the matching state between the positioning portion 13 and the positioning structure 22 is also correspondingly achieved. The elastic protrusion 3 and the recess 4 are respectively provided. If the positioning structure 22 is the recess 4, then the positioning portion 13 is correspondingly the elastic protrusion 3, as Figure 2 shown; if the positioning structure 22 is the elastic protrusion 3, then the positioning portion 13 is correspondingly the recess 4, as Figure 3As shown. In other words, in the embodiment of the present application, the matching state corresponding to each accommodating cavity 20 can be achieved by the snap-fitting between multiple elastic protrusions 3 and a recess 4; or, the matching state corresponding to each accommodating cavity 20 can also be achieved by the snap-fitting between multiple recesses 4 and an elastic protrusion 3. Among them, the characteristic of the elastic protrusion 3 is that, during the relative rotation between the assembly part 2 and the host 1, when the elastic protrusion 3 is outside the range of the recess 4, it can be compressed by other parts of the component where the recess 4 is located, and does not affect the rotation between the assembly part 2 and the host 1; when the elastic protrusion 3 enters the range of the recess 4, its elastic deformation is released, and the elastic protrusion 3 is inserted into the recess 4, and the elastic protrusion 3 is limited by the recess 4, and the elastic protrusion 3 is also relatively limited to the recess 4, which provides a sense of position for the operating user, so that the user can realize that the rotation process has been completed, and the user can know that a certain accommodating cavity 20 has entered the working state without checking with the naked eye. The limiting connection between the elastic protrusion 3 and the recess 4 is detachable. By applying a sufficiently large force to make the assembly continue to rotate relative to the main machine, the limiting connection between the elastic protrusion 3 and the recess 4 can be released. After the current accommodating cavity 20 is released from the working state, another accommodating cavity 20 can be put into the working state.

[0062] In some alternative embodiments, please refer to Figure 7 In the structure where a limiting connection is formed between the elastic protrusion 3 and the recess 4, in order to facilitate the release of the connection and positioning between the elastic protrusion 3 and the recess 4, while enhancing the positioning accuracy and positioning speed between the elastic protrusion 3 and the recess 4, the recess 4 may be further provided with a guide slope 41 along the rotation direction of the assembly part. The guide slope 41 may help guide the elastic protrusion 3 to disengage from the recess 4, and may also facilitate the elastic protrusion 3 to slide into the recess 4 along the surface of the guide slope 41, thereby enhancing the positioning accuracy and positioning speed.

[0063] In some alternative embodiments, please refer to Figure 8 , the specific structure of the elastic protrusion 3 may include a fixedly connected elastic connector 31 and a limiting protrusion 32; or, the elastic protrusion 3 is integrally formed of an elastic material. Among them, the elastic connector 31 includes a component with a certain elasticity such as a spring and a spring sheet. By connecting the elastic connector 31 with the limiting protrusion 32, and then connecting the elastic connector 31 to the installation position 10 or the assembly 2, the required elastic protrusion 3 is formed. Under the elastic deformation of the elastic connector 31, the elastic protrusion 3 does not affect the relative rotation between the assembly 2 and the host 1, and can achieve a limiting connection. In addition, the elastic protrusion 3 as a whole can be integrally formed of an elastic material, and the elastic material can include an elastic material such as silicone, or be directly formed of a spring sheet.

[0064] In some embodiments, the recess 4 may be a groove, a blind hole, etc., and the shape and size of the groove and the blind hole may be set according to the actual rotational accuracy requirements; compared with the blind hole, the groove has greater freedom and can allow the elastic protrusion 3 to form a limiting connection with it within a relatively large range.

[0065] In some alternative embodiments, in order to avoid affecting other accommodation cavities 20 when heating the accommodation cavity 20 in the working state and also avoid aerosol leakage, the aerosol generating device may further include a sealing assembly 7. When the fitting 2 is installed in the installation position 10, the sealing assembly 7 is elastically compressed between the fitting 2 and the installation position 10 to hermetically connect the air outlet 21 corresponding to the accommodation cavity 20 in the working state to the air outlet passage 11. Additionally, when the main body 1 further has an air inlet passage 12 and the bottom of the accommodation cavity 20 has an air inlet 23, the sealing assembly 7 is at the bottom of the fitting 2 and is elastically compressed between the fitting 2 and the installation position 10, and this sealing assembly 7 can also be used to hermetically connect the air inlet 23 corresponding to the accommodation cavity 20 in the working state to the air inlet passage 12. The sealing assembly 7 can also increase the damping between the fitting 2 and the main body 1, so that when the accommodation cavity 20 is in the working state, a relatively large external force is required to make the fitting 2 rotate again.

[0066] In some alternative embodiments, the sealing assembly 7 may specifically include an elastic sealing ring 71, and the elastic sealing ring 71 is disposed around the air outlet 21 and / or the air outlet passage 11 and abuts against the opposite end. That is to say, the elastic sealing ring 71 can be fixed on the fitting 2, or fixed on the main body 1, or disposed on both the fitting 2 and the main body 1 at the same time, and the two cooperate with each other to achieve a sealed connection. The elastic sealing ring 71 can press-fit the end face of the fitting 2 and the end face of the installation position 10 to achieve a sealed connection. Additionally, using the elastic sealing ring 71 to achieve the sealed connection between the air outlet 21 and the air outlet passage 11 can also improve the connection strength between the fitting 2 and the main body 1 and reduce the possibility of the fitting 2 detaching from the main body 1.

[0067] In some alternative embodiments, in order to ensure that only one accommodation chamber 20 is in a working state at the same time, a heat insulation layer may be provided on the outer periphery of each accommodation chamber 20; the aerosol generating device further includes a heating assembly configured to heat only the accommodation chamber 20 in the working state. By providing the heat insulation layer, the heat transferred to the outside can be reduced when the accommodation chamber 20 in the working state is working; correspondingly, the heating assembly for heating the heat insulation layer only heats the accommodation chamber 20 in the working state, and the other accommodation chambers 20 are not heated, preventing the aerosol generating articles in the other accommodation chambers 20 from being heated to generate aerosols. The heating method may specifically include magnetic induction heating, hot air heating, etc., and may also be infrared heating, microwave heating, resistance heating, etc. When using hot air heating, a heating assembly may be provided on the air inlet passage 12; in the use state, air will flow through the air inlet passage 12, be heated by the heating assembly and then flow to the accommodation chamber 20 in the working state to heat the aerosol generating article to generate aerosols, and then be output through the air outlet 21 and the air outlet passage 11 in sequence. When using magnetic induction heating, the heating assembly is specifically a magnetic field generating assembly, which is correspondingly adapted to the aerosol generating article provided with a magnetic induction heating element.

[0068] In the embodiment of the present application, an aerosol generating device is provided. Due to the positioning portions 13 and the positioning structures 22 respectively provided on the main body 1 and the fitting 2, when the fitting 2 is rotatably connected to the main body 1, the position of the accommodation chamber 20 can be quickly positioned, thereby realizing the matching of the working state of the corresponding accommodation chamber 20 and improving the user experience.

[0069] In addition, in the embodiment of the present application, an aerosol generating device is further provided. Please refer to Figure 9-14 As shown, the aerosol generating device includes a main body 1 and a fitting 2; wherein, the main body 1 has an installation position 10 and an air outlet passage 11, and the air outlet passage 11 communicates with the installation position 10; the fitting 2 is rotatably installed in the installation position 10; a plurality of accommodation chambers 20 are formed inside the fitting 2, and the accommodation chambers 20 are used for accommodating aerosol generating articles; the accommodation chamber 20 is provided with an air outlet 21; each accommodation chamber 20 has a working state. When any accommodation chamber 20 is rotated to the working state, the air outlet 21 of the accommodation chamber 20 communicates with the air outlet passage 11; the installation position 10 is provided with a positioning portion 13, and the fitting 2 is provided with a positioning structure 22. The positioning structure 22 and the positioning portion 13 have matching states corresponding to each accommodation chamber 20. In the matching state, the corresponding accommodation chamber 20 is in the working state.

[0070] In the embodiment of the present application, the limiting method for the rotational connection between the fitting 2 and the host 1 may further include: there are two receiving cavities 20; the installation position 10 is provided with a window 5, and positioning portions 13 are formed on the opposite two side edges of the window 5 along the rotational direction of the fitting 2, and the edges correspond to the receiving cavities 20 one by one; the positioning structure 22 is a stopper 6 protruding from the outer peripheral side of the fitting, and the stopper 6 is limited to move within the window 5 as the fitting 2 rotates; when the stopper 6 abuts against the edge, the corresponding receiving cavity 20 is in a working state. In the embodiment of the present application, by providing the window 5 and the stopper 6, during the relative rotation of the fitting 2 and the host 1, the stopper 6 is driven to move within the space formed by the window 5. Therefore, the stopper 6 is blocked by the opposite two side edges of the window 5. Since the number of receiving cavities 20 is two, and the number of the opposite two side edges of the window 5 is also two, the two edges respectively correspond to the two receiving cavities 20. When the stopper 6 rotates to abut against one side edge, one of the receiving cavities 20 enters the working state; when the stopper 6 rotates to abut against the other side edge, the other receiving cavity 20 enters the working state. That is to say, when the user operates, only by rotating the fitting 2 in a certain direction, through the connection relationship of the abutment between the stopper 5 and the edge, a sense of being in place is provided for the user, and the user can know that a certain receiving cavity 20 enters the working state without visually checking with the naked eye.

[0071] In some alternative embodiments, please refer to Figure 9 As shown, there may be one stopper 6. When the stopper 6 abuts against the edge on one side, one of the receiving cavities 20 is in a working state. When the stopper 6 abuts against the edge on the other side, the other receiving cavity 20 is in a working state; that is to say, the end faces on both sides of the stopper 6 respectively abut against the two side edges of the window 5 to respectively correspond to one of the receiving cavities 20 being aligned and communicated with the air outlet channel 11.

[0072] Or, please refer to Figure 10 and 11 As shown, there may also be two stoppers 6 corresponding to the receiving cavities 20 one by one. When the stopper 6 abuts against the corresponding edge, the corresponding receiving cavity 20 is in a working state. In this structure, the degrees of freedom in the setting positions of the receiving cavity 20 and the stopper 6 are greater and can be adjusted according to the actual structure of the window 5.

[0073] In some alternative embodiments, such as Figure 13 and 14As shown, in order to realize the reuse of the structure and function of window 5, window 5 can also be used as the entrance for the fitting 2 to be installed in the installation position 10; the accommodation cavities 20 are symmetrically arranged on the fitting 2; the included angles A formed by the two side edges of window 5 and the rotation axis of the fitting 2 facing the window are greater than 180°, and there are two stoppers 6 respectively corresponding to the accommodation cavities 20. In order to insert the fitting 2 into the installation position 10 along window 5, the opening size of window 5 should have a certain range, which is at least half the size of the rotation trajectory of the outer peripheral side of the fitting 2; the larger the opening of the window, the easier the assembly, and the larger the spatial range for the stopper 6 to rotate. If the included angle A formed by the two side edges of window 5 and the rotation axis of the fitting 2 facing the window is greater than 180°, it means that the rotation range of the fitting 2 in the window is relatively large. In order to better realize the limit, two stoppers 6 can be set. The two stoppers 6 respectively correspond to one side edge of window 5, that is, when rotating in the first direction, one stopper 6 abuts against one side edge, and at this time one of the accommodation cavities 20 is in the working state; when rotating in the reverse direction of the first direction, the other stopper 6 abuts against the other side edge, and at this time the other accommodation cavity 20 is in the working state. By setting two stoppers 6, while making the size of window 5 larger, the rotation range of the fitting 2 can be limited, so that the accommodation cavity 20 can match the actual rotation range of each stopper 6. Among them, the included angle A formed by the two side edges of window 5 and the rotation axis of the fitting 2 facing window 5 is greater than 180°, indicating that most of the fitting 2 is exposed outside window 5, and only a small part is located inside window 5. In this case, the rotation range of the fitting 2 can be limited by setting two stoppers 6.

[0074] Alternatively, if the two side edges of window 5 and the rotation axis of the fitting 2 are in the same plane, then there is one stopper 6. The two side edges of window 5 and the rotation axis of the fitting 2 being in the same plane belong to the extreme state of assembling the fitting 2 in the installation position 10. Approximately half of the structure of the fitting 2 is exposed outside window 5, and the other half is located inside window 5. In this case, only one stopper 6 can be set to realize the position switching corresponding to each accommodation cavity 20.

[0075] The aerosol generating device of the present application is used to heat the aerosol generating article. In one embodiment, the aerosol generating article can only have a smoke generating matrix section and a wrapper wrapped outside the smoke generating matrix section; the smoke generating matrix can include at least one of tobacco and / or non-tobacco smoke generating materials and their mixtures, and a cooling section or a filtering section etc. may not be provided downstream of the smoke generating matrix section, so that the cost of the aerosol generating article can be saved.

[0076] In an embodiment of the present application, an aerosol generating device is provided, which has a plurality of accommodating cavities 20. In this way, multiple aerosol generating articles can be loaded at one time each time it is used, and the duration that can be used after each replacement operation is longer, making it more convenient to use. Further, due to the positioning parts 13 and the positioning structures 22 respectively provided on the main body 1 and the fitting 2, when the fitting 2 is rotatably connected to the main body 1, the positions of the accommodating cavities 20 can be quickly positioned, so that the working states of the corresponding accommodating cavities 20 are matched, improving the user experience.

[0077] The present application also provides an aerosol generating system. Please refer to Figure 15 , the aerosol generating system includes an aerosol generating article 8 and the aerosol generating device of any one of the above embodiments.

[0078] The aerosol generating device in the aerosol generating system can be the aerosol generating device involved in any one of the above embodiments and achieve the same or similar functions, which will not be elaborated herein.

[0079] In some embodiments, the aerosol generating article 8 may include a fuming matrix section, and the fuming matrix section may include a fuming matrix and a wrapper for wrapping the fuming matrix. The fuming matrix may include at least one of tobacco-based and non-tobacco-based fuming substances. For example, the non-tobacco fuming substance may include fibers adsorbed with glycerol and propylene glycol, etc. In addition, the fuming matrix may also include other components. The aerosol generating article 8 may also be a solid fuming matrix block. Herein, the "solid fuming matrix block" means that the whole fuming matrix block is a formed body, rather than a loose form such as bulk particles or bulk filaments and flakes. For example, the fuming matrix block may be formed by extruding or stamping the fuming matrix to form a formed body with a certain air permeability. The fuming matrix block may be solidified from a mixture of tobacco or non-tobacco plants, as well as fuming agents, polysaccharides, etc. Structures such as a cooling section for cooling and a filter section for filtering in the existing aerosol generating article 8 can be omitted.

For those skilled in the art of the present invention, based on the idea of the present invention, several simple deductions, deformations or replacements can also be made.
