Description

Technical Field

[0001] The utility model relates to the field of heat-not-burn electronic smoking devices, in particular to an aerosol generating device and an aerosol generating system. Background Art

[0002] As health awareness grows, consumers are increasingly demanding tobacco products that reduce tar and harm, while pursuing nicotine satisfaction. The global market is in urgent need of innovative new tobacco products. In recent years, new tobacco products designed to reduce the release of harmful ingredients and the risk of smoking have seen explosive growth, and the development of heated tobacco devices has become a focus of attention.

[0003] Currently, the heating methods of smoking devices are mainly divided into two forms: internal core heating and external heating. Internal core heating is when the heating element is a heating plate or a heating needle, which is inserted into the inside of the cigarette to heat the tobacco product in direct contact. External heating is when the heating element is a cylindrical heating chamber, which heats the outer surface of the tobacco product. Whether it is a heated smoking device with internal core heating or external heating, the cleaning problem of the heated smoking device has always been a pain point that users cannot completely solve. In particular, during the heating process, condensation and heating residues are easily accumulated on the inner wall and bottom of the heating chamber of the smoking device. If the smoking device is not thoroughly cleaned after each use, the residue will be heated again during the next heating and puffing. In turn, this will not only affect the taste of the newly heated cigarette, but may also lead to health risks caused by multiple heating pollution. Therefore, it is imperative to conveniently and thoroughly solve the cleaning problem of heated smoking devices.

[0004] In the development and promotion of new tobacco products, consumers, manufacturers, and research institutions need to work together to continuously improve product design and user experience through technological innovation and market research. Future new heated tobacco devices will undoubtedly reach new heights in cleanliness and health, providing consumers with a safer and more comfortable experience and meeting their growing health needs.

In order to provide a deep understanding of the present utility model, many specific details will be included in the following description. The present utility model can also be implemented without these details. In addition, in order to avoid confusing or obscuring the key points of the present utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0042] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] The terms "first", "second", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0044] In the description of this embodiment, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0045] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings.

[0046] In the present utility model, preferably, the aerosol generating article can be a smoking article in the shape of a cigarette; more preferably, the aerosol generating article is a solid aerosol generating article, including but not limited to tobacco sheets, tobacco granules, cut tobacco, reconstituted tobacco, etc., which are tobacco products that can be heated by a heating device to generate smoke for a user to inhale. Among them, the heating device is also the aerosol generating device.

[0047] As Figures 1-5 shown, the present utility model provides an aerosol generating device 0, which has an axis, and the axis is, for example, Figures 1-5 the x direction as shown, and includes: a first body 1, the first body 1 includes a receiving cavity 11, and the receiving cavity 11 extends through the first body 1 along the axis (for example Figures 1-5 the x direction as shown), and the receiving cavity 11 is used to receive the aerosol generating article 00 (as Figure 8 shown); the receiving cavity 11 includes a first opening 111 and a second opening 112, and the insertion end 01 of the aerosol generating article (as Figure 8 shown) can be inserted into the receiving cavity 11 from the first opening 111 to the second opening 112, and the heating element 13 can be used to heat the aerosol generating article 00 received in the receiving cavity 11. Among them, the heating element 13 and the receiving cavity 11 are fixedly connected.

[0048] A second body 2, along the axis (for example Figures 1-5The x direction shown in the figure) is docked with the first main body 1 and has a first docking end 22, and the first docking end 22 is provided with a collecting portion 21; it should be noted that the collecting portion 21 of the present invention includes a recessed portion 21' and / or absorbent cotton, etc., which can be used to receive the residue from the aerosol generating product 00 after being heated.

[0049] The first body 1 has a first position and a second position relative to the second body 2. In the first position (for example Figure 1 As shown), the collecting portion 21 and the accommodating chamber 11 are arranged in an axial direction (eg Figures 1-5 The heating element 13 can heat the aerosol generating product 00 contained in the accommodating cavity 11, and the collecting portion 21 can be used to receive the residue from the aerosol generating product 00 after being heated; in the second position (e.g. Figures 2-5 As shown), the accommodating cavity 11 is away from the collecting portion 21, so that the collecting portion 21 is exposed and the residue on the collecting portion 21 can be cleaned. That is, the second body 2 is movably connected to the first body 1; when in the first position, the second body 2 is axially (for example Figures 1-5 when in the second position, the position of the first body 1 relative to the second body 2 changes, so that the collecting portion 21 is exposed.

[0050] Since the aerosol-generating article 00 is located in the accommodating chamber 11, when heated by the heating device, it will produce residues such as end threads, residues, and condensate. Therefore, the collection portion 21 at the bottom of the accommodating chamber 11 can receive these residues, thereby preventing them from contaminating other components of the smoking device. At this time, the relative positions of the second body 2 and the first body 1 can be changed, exposing the collection portion 21 at the first docking end 22, thereby exposing the residues and allowing the user to clean the smoking device very conveniently.

[0051] By adopting the above technical solution, the present invention divides the aerosol generating device 0 into a modular design of a first body 1 and a second body 2, and sets a receiving cavity 11 and a heating element 13 in conjunction with the first body 1, and Figures 1-5The collection part 21 of the second body 2 is disposed opposite to the accommodation cavity 11 in the x-direction (as shown), so that residues such as end filaments and condensate generated after heating the aerosol generating article 00 in the accommodation cavity 11 can be effectively received and accommodated by the collection part 21, preventing contamination of other components of the smoking device. By cooperating with the position change of the first body 1 relative to the second body 2, the collection part 21 is exposed, allowing the user to easily clean the residues. Therefore, through the mutual cooperation of the above entire technical solution, not only the cleaning efficiency, cleaning effect and user experience of the smoking device are improved, the maintenance difficulty is reduced, and the service life of the smoking device is extended. In addition, after each use, since the smoking device can be cleaned cleanly, it is also beneficial to enhance the user's purer smoking experience.

[0052] In some possible embodiments provided by the present utility model, in the first position, at least a part of the side surface of the insertion end 01 of the aerosol generating article can pass through the second opening 112 and be placed outside the second opening 112. Since a part of the insertion end 01 of the aerosol generating article protrudes out of the second opening 112, when the aerosol generating article 00 is heated, the liquid or residue generated can directly leak out completely from the second opening 112, and hardly adheres to the side wall of the accommodation cavity around the second opening 112, thus facilitating almost cleaning-free.

[0053] As Figure 3 In the embodiment shown, the collection part 21 of the present utility model is, for example, a recessed part 21', and the recessed part 21' is used to receive the residues from the accommodation cavity 11; preferably, in the first position, the recessed part 21' can abut against the insertion end 01 of the aerosol generating article 00. More preferably, the recessed part 21' can deform the insertion end, as Figure 8 shown; that is, when the aerosol generating article 00 is inserted into the accommodation cavity 11 until it abuts against the inner wall of the recessed part 21', the recessed part 21' exerts an external force on the insertion end 01 of the aerosol generating article, causing the insertion end 01 to be squeezed and deformed, and then at least partially compressing the insertion end 01. This can not only effectively fix the aerosol generating article 00 at an appropriate position in the accommodation cavity 11, prevent the insertion end 01 of the aerosol generating article from protruding excessively from the second opening 112, but also prevent and / or reduce the residue of the atomizable substance (such as tobacco shreds and tobacco residues) of the aerosol generating article 00 from falling. Thus, while avoiding the generation of end residues at the insertion end, the residues are all received by the recessed part 21', and the inner wall of the accommodation cavity 11 is also prevented from being contaminated, which is beneficial to further solving the cleaning problem of the heated smoking device. Among them, the part of the recessed part 21' of the present utility model that abuts against the insertion end 01 of the aerosol generating article includes an angle with the axial direction (such as Figures 1-5 shown in the x-direction) (such as Figure 8The curved surface or inclined surface set in β) therein. Preferably, the angle β is 20° to 70°, so as to ensure that air can enter the aerosol generating article 00 while squeezing and deforming the insertion end 01, thereby ensuring that the suction resistance for the user is appropriate; specifically, the inclined surface can be a single inclined surface or a double inclined surface. Preferably, the center line of the accommodating cavity 11 deviates from the lowest end of the recess 21' to provide a portion that abuts against the insertion end 01 of the aerosol generating article.

[0054] In Figure 2 and Figure 3 In the embodiment shown, the second body 2 and the first body 1 are movably connected by magnetic attraction, so that the first body 1 and the second body 2 are detachably connected. Thus, the second body 2 and the first body 1 can be easily detachably connected. Magnetic attraction connection is actually a type of pull-out connection, that is, when an external force is applied to the aerosol generating device 0, it can be disassembled into two independent modules, the second body 2 and the first body 1 (as shown in Figure 2 ). The two independent modules, the second body 2 and the first body 1, can be reconnected into an integrated aerosol generating device 0 through magnetic attraction. The magnetic attraction connection not only ensures the stability of the connection but also provides a convenient disassembly method. Users can quickly separate the first body 1 and the second body 2 for cleaning and maintenance, greatly improving the operability and convenience of use of the device. In addition, the magnetic attraction connection avoids complex mechanical structures, reduces the failure points, and extends the service life of the device.

[0055] Specifically, referring to Figure 3 shown, in this embodiment, 2 first magnet blocks 141, 142 are arranged in the first body 1. The 2 first magnet blocks 141, 142 are respectively arranged on both sides of the second docking end 12 along the first direction (such as the y direction shown in Figures 2-6 ), and the 2 first magnet blocks 141, 142 are fixedly connected to the inner wall of the second docking end 12. The first direction (such as the y direction shown in Figures 2-6 ) is perpendicular to the axial direction (for example, the x direction shown in Figures 1-5 ), that is, the first direction (such as the y direction shown in Figures 2-6 ) is the length direction of the aerosol generating device 0 in the embodiment. Correspondingly, 2 second magnet blocks 231, 232 are also arranged in the second body 2. The 2 second magnet blocks 231, 232 are respectively arranged on both sides of the first docking end 22 along the first direction (such as the y direction shown in Figures 2-6 ), and the 2 second magnet blocks 231, 232 are fixedly connected to the inner wall of the first docking end 22, and the 2 first magnet blocks 141, 142 and the 2 second magnet blocks 231, 232 are along the axial direction (for example Figures 1-5The two first magnet blocks 141 and 142 are oppositely arranged in the x direction (as shown). At this time, when the two first magnet blocks 141 and 142 are respectively docked with the two second magnet blocks 231 and 232, the second main body 2 and the first main body 1 are connected. In addition, the first magnet blocks 141 and 142 are arranged inside the first main body 1, and the second magnet blocks 231 and 232 are arranged inside the second main body 2, without being exposed outside the casings of the first main body 1 and the second main body 2, so that users do not need to consider the impact on the first magnet blocks 141 and 142 and the second magnet blocks 231 and 232 when cleaning the smoking device, which is also beneficial to improving the stability of magnetic connection use. Thus, users can conveniently disassemble the first main body 1 and the second main body 2 to better clean the smoking device. In some possible embodiments provided by the present utility model, the specific magnetic field intensity of the first magnet blocks 141 and 142 or the second magnet blocks 231 and 232 is not limited.

[0056] Reference Figure 4 And Figure 6 As shown, in this embodiment, the movable connection between the second main body 2 and the first main body 1 is a hinge connection, and the first main body 1 can be flipped relative to the second main body 2 through the hinge. That is to say, users only need to flip the first main body 1 to expose the collection part 21, and then can clean the smoking device, bringing a more convenient and reliable use experience to users.

[0057] Specifically, in some possible embodiments provided by the present utility model, the hinge connection is a flip-type connection. The first docking end 22 is on one side along the second direction (such as Figure 4 And Figure 6 Shown in the z direction) and the second docking end 12 corresponds to the same side along the second direction (such as Figure 4 And Figure 6 Shown in the z direction) are connected through the hinge part 16, thereby realizing the hinge connection between the second main body 2 and the first main body 1. Thus, the first main body 1 takes the axis where the hinge part 16 is located as the rotation axis, and the first main body 1 can be flipped relative to the second main body 2, and the position of the first main body 1 changes, so that the collection part 21 is at least partially or completely exposed. Specifically, the hinge part 16 includes structures such as hinges, pins, and pin holes that can realize hinge connection. Among them, the second direction (such as Figure 4 And Figure 6 Shown in the z direction) is perpendicular to the axial direction (for example Figures 1-5 Shown in the x direction), and the axial direction (for example Figures 1-5 Shown in the x direction), the first direction (such as Figures 2-6 Shown in the y direction), and the second direction (such as Figure 4 And Figure 6 Shown in the z direction) intersect pairwise, that is, the second direction (such as Figure 4 And Figure 6 Shown in the z direction) is the width direction of the aerosol generating device 0 in the embodiment.

[0058] Reference Figure 5 As shown, in this embodiment, the first main body 1 of the present utility model is connected to the second main body 2 through a rotating shaft 15. The rotating shaft 15 is perpendicular to the first docking end 22. The first main body 1 can rotate relative to the second main body 2 along the rotating shaft 15. That is, the connection mode between the first main body 1 and the second main body 2 is a rotary connection. Thus, the user can adjust the position of the first main body 1 through a simple rotation action, so that the collection part 21 is exposed, facilitating cleaning, maintenance, inspection or replacement of internal components. And through the connection mode of the rotating shaft 15, the smoothness and accuracy of the operation are improved. At the same time, it is beneficial to maintain the compactness of the device, improving the overall operation convenience and user experience.

[0059] Specifically, in some possible embodiments provided by the present utility model, one side of the first docking end 22 along the first direction (such as Figures 2-6 the y direction shown) and the corresponding side of the second docking end 12 along the first direction (such as Figures 2-6 the y direction shown) are connected through the rotating shaft 15, thereby realizing the connection between the second main body 2 and the first main body 1 through the rotating shaft 16. Thus, the first main body 1 takes the axis where the rotating shaft 15 is located as the rotation axis, and the first main body 1 can rotate clockwise or counterclockwise relative to the second main body 2, and the positions of the first main body 1 and the second main body 2 are relatively staggered, so that the collection part 21 is at least partially or completely exposed. Further, the rotating shaft 16 includes a shaft and a shaft seat. One shaft seat is provided on each of one side of the first docking end 22 and the second docking end 12 along the first direction (such as Figures 2-6 the y direction shown). The two shaft seats are arranged oppositely along the axial direction (for example Figures 1-5 the x direction shown). The two ends of the shaft are respectively inserted and connected to the two shaft seats, thereby connecting the second main body 2 and the first main body 1 through the rotating shaft 16.

[0060] Further, continuing to refer to Figure 1 shown, there is a gap 102 between the first main body 1 and the second main body 2, and the aerosol generating device 0 intakes air through the gap 102. That is to say, the gap 102 is the air intake channel of the aerosol generating device 0, and external air enters the internal accommodation cavity 11 through the gap 102. Thus, the structure of the aerosol generating device 0 is simplified, no additional air path design is required, and good air flow distribution is ensured. And the air intake channel is exactly located between the first docking end 22 and the second docking end 12. Combining with the way of the movable connection between the second main body 2 and the first main body 1, the user can clean the air intake channel while cleaning the residues, which is beneficial to further enhancing the user's suction experience.

[0061] Preferably, the accommodation cavity 11 of the present utility model is along the axial direction (for example Figures 1-5a through - type structure from top to bottom in the x - direction (as shown); more preferably, the accommodating cavity 11 has a constant - diameter straight - through structure along the axial direction (e.g., Figures 1-5 the x - direction as shown). Thus, it can avoid the cleaning dead - ends caused by complex cavity structures, making it easy for residues to be discharged, preventing the accumulation of residues, reducing the maintenance difficulty, being more conducive to cleaning, reducing the dirt, condensate and bacterial growth inside the smoking device, and being more hygienic and healthy. Moreover, the accommodating cavity 11 with a constant - diameter straight - through structure is beneficial to providing a uniform air - flow channel when heating the aerosol - generating article 00, reducing the air - flow resistance, ensuring the stability of the aerosol - generating process, and also being beneficial to ensuring the long - term stable operation and excellent performance of the aerosol - generating device.

[0062] Furthermore, in this embodiment, the depth of the recess 21' along the axial direction (e.g., Figures 1-5 the x - direction as shown) is 1 - 2 mm. Setting the depth of the recess 21' within the above range can not only ensure that the recess 21' can effectively accommodate the residues from the inside of the accommodating cavity 11, such as end - falling filaments, condensate, etc., and prevent them from spreading to other components, but also facilitate thorough cleaning with tools, etc., reducing the cleaning dead - ends, improving the cleaning efficiency, making the cleaning process more convenient, and reducing the maintenance cost. In addition, it can assist the constant - diameter straight - through accommodating cavity 11 in limiting the aerosol - generating article 00, especially the recess 21' that deviates from the center line of the accommodating cavity 11.

[0063] In some possible embodiments provided by the present utility model, as Figure 7 shown, the aerosol - generating device 0 further includes two waterproof covers 3, and the two waterproof covers 3 respectively cover both ends of the first body 1 along the axial direction (e.g., Figures 1-5 the x - direction as shown) for sealed connection. At this time, the user can also clean the smoking device by means of water washing, which is more convenient and the cleaning effect of water washing is also better. Specifically, the shape of the waterproof cover 3 is the same as the shapes of the two end faces of the first body 1 along the axial direction (e.g., Figures 1-5 the x - direction as shown). One of the end faces is, for example, the second docking end 12, that is to say, the shape of the waterproof cover 3 is the same as the shape of the second docking end 12, so that the two waterproof covers 3 correspondingly cover the two end faces. A silica gel ring 31 can also be provided between the waterproof cover 3 and the first body 1 to further improve the tightness of the connection between the waterproof cover 3 and the first body 1, thereby improving the waterproof performance of the first body 1 and the reliability of the long - term stable operation of the aerosol - generating device. Similarly, the second body 2 can also be provided with a waterproof cover 3, that is to say, the shape of the waterproof cover 3 is also the same as the shape of the first docking end 22 to seal the first docking end 22. Further, a silica gel ring 31 can be provided between the waterproof cover 3 and the second body 2, which will not be elaborated here. Therefore, through the above - mentioned settings, the cleaning effect and convenience of the smoking device are further improved to achieve thorough cleaning of the smoking device.

[0064] In some possible embodiments provided by the present utility model, the first body 1 includes a heating element 13, and the heating element 13 is disposed on the outer periphery of the accommodation cavity 11 or defines the accommodation cavity 11. Thus, the problem of uneven heating of the aerosol generating article 00 is reduced by providing a uniform heat distribution by the heating element 11, and the quality of the generated aerosol is improved. Among them, the heating element 13 defines the accommodation cavity 11, that is, at least a part of the heating element 13 forms at least a part of the accommodation cavity 11, that is, at least a part of the heating element 13 also serves as at least a part of the accommodation cavity 11. The heating methods of the present utility model include but are not limited to electromagnetic heating, resistance heating, or infrared heating, etc. For the electromagnetic heating method, the susceptor serves as the heating element 13, which defines the accommodation cavity 11. Further, the first body 1 further includes a housing 10, and the accommodation cavity 11 is hermetically connected to the housing 10. Through the cooperative sealing arrangement, it is more convenient to clean. For example, the smoking device can be cleaned by water washing, and the above-mentioned heating element 13 and the circuit will not be damaged. Only the heating element 13 needs to be dried after water washing, and then it can be used continuously, which also ensures the reliability of the use of the aerosol generating device 0.

[0065] Preferably, the heating element 13 is sleeved on the outer periphery of the accommodation cavity 11, avoiding direct contact between the heating component and the tobacco product. Therefore, when the user considers cleaning the accommodation cavity 11 of the smoking device, there is no need to worry about damaging the heating element. Therefore, while ensuring efficient heating, the cleaning and maintenance experience can be optimized, and the reliability of the device use and user satisfaction are enhanced. For example, referring to Figure 3 As shown, in the embodiment of the present utility model, the heating element 13 of the present utility model is a heating tube, and the heating tube is sleeved on the outer periphery of the accommodation cavity 11.

[0066] Further, both ends of the heating element 13 along the axial direction (for example, the x direction as shown in Figures 1-5 ) are respectively 2 to 3 mm away from both ends of the first body 1 along the axial direction (for example, the x direction as shown in Figures 1-5 ). The above setting, on the one hand, prevents the temperature at the downstream end of the aerosol generating article 00 from being too high, resulting in a poor suction taste for the user; on the other hand, it prevents the temperature from being too high when the collection part 21 is exposed, which may scald the user, and is beneficial for the user to safely clean the smoking device.

[0067] In some possible embodiments provided by the present utility model, Figure 3 Combined with Figure 6As shown, the first body 1 has a second docking end 12. The second docking end 12 is provided with first conductive electrodes 121 and 122, and the first docking end 22 is provided with second conductive electrodes 221 and 222. When the second body 2 is docked with the first body 1, the first conductive electrodes 121 and 122 are in contact and conduct electricity with the second conductive electrodes 221 and 222. Preferably, the first conductive electrodes 121 and 122 and the second conductive electrodes 221 and 222 are arranged oppositely along the axial direction (for example Figures 1-5 the x direction shown). That is to say, one of the first conductive electrodes 121 and 122 is provided on the second docking end 12, and the first docking end 22 is correspondingly provided with the second conductive electrodes 221 and 222 along the axial direction (for example Figures 1-5 the x direction shown). Furthermore, when the second body 2 is docked with the first body 1, the first conductive electrodes 121 and 122 are in contact and conduct electricity with the second conductive electrodes 221 and 222 to realize the electrical connection between the first body 1 and the second body 2; when the second body 2 is separated from the first body 1 or the relative position changes, the first conductive electrodes 121 and 122 and the second conductive electrodes 221 and 222 may not be in contact and conduct electricity, and the circuit between the first body 1 and the second body 2 can be disconnected.

[0068] Through the above settings, the electrical connection or circuit disconnection between the first body 1 and the second body 2 is realized, which simplifies the circuit connection structure of the smoking device and realizes the fast and stable electrical connection between the first body 1 and the second body 2. At the same time, when the second body 2 is separated from the first body 1 or the relative position changes, the circuit can be conveniently disconnected. On the one hand, it can prevent problems such as the first body 1 being continuously heated to cause dry burning, overheating damage to the smoking device or scalding the user when the first body 1 and the second body 2 are accidentally separated or the relative position changes; on the other hand, the user does not need to worry about electric shock and other accidents when directly cleaning the smoking device when forgetting to turn off the circuit of the smoking device. In addition, the above-set electrical connection method also reduces the use of cables and connectors, avoids complex internal circuit layouts, and reduces potential fault points. Furthermore, the dead corners during the cleaning of the smoking device are also correspondingly reduced, making the cleaning work more thorough. Therefore, this setting not only realizes convenient and stable electrical connection, but also greatly improves the cleaning effect and maintenance convenience of the smoking device, thereby improving the overall performance and user satisfaction, and providing a reliable guarantee for the long-term stable operation of the aerosol generating device 0.

[0069] Specifically, the first conductive electrodes 121 and 122 of the present utility model are arranged inside the first body 1 and are respectively arranged on both sides of the second docking end 12 along the first direction (such as Figures 2-6 the y direction shown), and at least a part of the first conductive electrodes 121 and 122 protrudes from the second docking end 12 along the axial direction (for example Figures 1-5 the x direction shown). The second conductive electrodes 221 and 222 are arranged inside the second body 2 and are along the first direction (such asFigures 2-6 y direction shown) are respectively disposed on both sides of the first docking end 22, and at least a portion of the second conductive electrodes 221, 222 is axially (eg Figures 1-5 The x direction shown in the figure protrudes from the first docking end 22. This is beneficial to improving the reliability of the electrical connection between the first body 1 and the second body 2.

[0070] In the above-mentioned embodiments, the second body 2 of the present invention includes a circuit board and a battery 25. The circuit board and battery 25 are connected to the second conductive electrodes 221 and 222. When the first body 1 and the second body 2 are docked, the first conductive electrodes 121 and 122 and the second conductive electrodes 221 and 222 are in contact and connected, thereby achieving electrical connection of the entire aerosol generating device 0. Specifically, the circuit board includes a main circuit board 24 and a charging circuit board 26. The main circuit board 24 is used to control the operation of the heating element 13 of the aerosol generating device 0, the electrical connection between the first body 1 and the second body 2, and to detect heating circuit failures. Furthermore, to prevent the conductive liquid used when cleaning the smoking device from causing the second conductive electrodes 221 and 222 to come into contact with the conductive liquid and thus become connected, the main circuit board 24 also includes a detection unit to detect the connection signal of the second conductive electrodes 221 and 222. The connection signal may include current, voltage, power, etc. The device then determines whether the connection signal is caused by the electrical connection between the first and second bodies 1 and 2, or by some other unexpected event. If the connection signal is detected to be caused by the electrical connection between the first and second bodies 1 and 2, the smoking device operates normally; if the connection signal is detected to be caused by an unexpected event, the smoking device does not operate. The charging circuit board 26 is used to control the charging and discharging of the battery 25 and to detect battery status, including overheating.

[0071] The present utility model provides an aerosol generating system, comprising the aerosol generating device 0 and the aerosol generating product 00 in any of the above embodiments.

[0072] By adopting the above technical solution, the user can clean the aerosol generating device 0 conveniently, thereby improving the cleaning efficiency of the aerosol generating device 0 and the user's inhalation experience, reducing the maintenance difficulty, and extending the service life of the aerosol generating device 0.

[0073] In summary, through the modular design concept, specifically, the entire aerosol generating device 0 is axially divided into two modules: the first main body 1 and the second main body 2. The first main body 1 may include a receiving cavity 11, a heating element 13, first magnet blocks 141, 142, and first conductive electrodes 121, 122. Among them, the housing of the first main body 1 can be made of heat-insulating material to improve the comfort of users. The second main body 2 may include a collection part 21, second magnet blocks 231, 232, second conductive electrodes 221, 222, a circuit board, and a battery 25. Furthermore, through the mutual cooperation of the components of the first main body 1 and the second main body 2, the efficiency and safety of the process of the smoking device heating to generate aerosol are ensured. Among them, the receiving cavity 11 adopts a through design from top to bottom, and the generated condensate and tobacco residue are better accommodated in the recessed part 21' (i.e., the collection part 21) of the second main body 2. With the movable connection between the first main body 1 and the second main body 2, it is convenient and simple for users to clean the smoking device. And the first main body 1 and the second main body 2 can achieve power-on communication or circuit disconnection through the electrode conductive sheet, improving the safety of users and the simplicity of cleaning the smoking device, and further thoroughly solving the cleaning problem of the smoking device.
