Description

Technical Field

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

[0002] As the market's health awareness grows, consumers are pursuing nicotine satisfaction while demanding higher and higher levels of tobacco products that reduce tar and harm. The global market's demand for innovation in new tobacco products has become extremely urgent. In recent years, new tobacco products that reduce the release of harmful ingredients and the risk of smoking have shown explosive growth, and the development of heated tobacco products has become a focus of attention.

[0003] At present, the heating methods of tobacco utensils are mainly divided into two forms: inner core heating and outer peripheral heating. Inner core heating is when the heating element is a heating sheet or a heating needle, and the tobacco products in direct contact are heated by inserting the heating element into the cigarette, while outer peripheral heating is when the heating element is a cylindrical heating chamber, and the outer surface of the tobacco products is heated by the heating chamber. Whether it is a heated tobacco utensil with inner core heating or outer peripheral heating, the cleaning problem of the heated tobacco utensil 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 tobacco utensil. If the tobacco utensil is not thoroughly cleaned after each use, the residue will be heated again during the next heating and puffing. Furthermore, it will not only affect the taste of the newly heated cigarettes, but may also lead to health risks caused by multiple heating pollution. Therefore, it is urgent to conveniently and thoroughly solve the cleaning problem of heated tobacco utensil.

[0004] In the process of developing and promoting 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. In the future, new heated tobacco products will surely reach new heights in terms of cleanliness and health, providing consumers with a safer and more comfortable experience and meeting their growing health needs.

[0041] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may extend based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

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

[0043] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0044] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0045] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] In the present invention, preferably, the aerosol generating product may be a smoking product in the shape of a cigarette; more preferably, the aerosol generating product is a solid aerosol generating product, including but not limited to tobacco flakes, tobacco particles, tobacco shreds, reconstituted tobacco and the like, which can be heated by a heating device to generate smoke for the user to inhale, wherein the heating device is also an aerosol generating device.

[0047] like Figure 1-5 As shown, the present invention provides an aerosol generating device 0, having an axial direction, the axial direction is for example Figure 1-5 In the x direction shown in the figure, the first body 1 includes a first body 1, the first body 1 includes a receiving cavity 11, and the receiving cavity 11 is axially (for example Figure 1-5 The x direction shown in the figure) penetrates the first body 1, and the accommodating cavity 11 is used to accommodate the aerosol generating article 00 (such as Figure 8 The accommodating chamber 11 includes a first opening 111 and a second opening 112, and the insertion end 01 of the aerosol generating article (as shown in Figure 8 As shown in FIG. 1 , the heating element 13 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 product 00 received in the receiving cavity 11. The heating element 13 and the receiving cavity 11 are fixedly connected.

[0048] The second body 2 is axially (eg Figure 1-5 The first butt joint 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 residues 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 axially (eg Figure 1-5The heating element 13 can heat the aerosol generating product 00 contained in the containing cavity 11, and the collecting portion 21 can be used to receive the residue from the aerosol generating product 00 after being heated; at the second position (e.g. Figure 2-Figure 5 As shown in FIG. 1 , 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 removed. 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 (e.g. Figure 1-5 When in the second position, the first body 1 changes position relative to the second body 2, so that the collecting portion 21 is exposed.

[0050] Since the aerosol generating product 00 is located in the accommodating cavity 11, when the aerosol generating product 00 is heated by the heating device, residues such as end threads, residues, condensed liquid, etc. will be generated. Therefore, the collecting portion 21 located at the bottom of the accommodating cavity 11 can receive the end threads, condensed liquid, etc. residues, thereby avoiding contamination of other parts of the smoking device. At this time, the relative positions of the second body 2 and the first body 1 can be changed, so that the collecting portion 21 located at the first docking end 22 is exposed, thereby also exposing the residues, and the user can 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 cooperation with the first body 1, and Figure 1-5 The collecting portion 21 of the second main body 2 is arranged opposite to the accommodating chamber 11 in the x direction as shown, so that the residues such as end threads and condensate generated after the aerosol generating product 00 in the accommodating chamber 11 is effectively received and contained by the collecting portion 21, thereby preventing contamination of other parts of the smoking device. And by coordinating the position change of the first main body 1 relative to the second main body 2, the collecting portion 21 is exposed, and the user can easily clean the residue. Therefore, through the mutual cooperation of the above-mentioned entire technical solution, not only the cleaning efficiency, cleaning effect and user experience of the smoking device are improved, the difficulty of maintenance is reduced, and the service life of the smoking device is extended. In addition, after each use, since the smoking device can be cleaned, it is also conducive to enhancing the user's purer smoking experience.

[0052] In some possible embodiments provided by the present invention, in the first position, at least a portion 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 portion of the insertion end 01 of the aerosol-generating article protrudes out of the second opening 112, liquid or residue generated when the aerosol-generating article 00 is heated can all be directly leaked out from the second opening 112, and will almost not adhere to the side wall of the accommodating cavity around the second opening 112, thereby facilitating substantially cleaning-free.

[0053] like Figure 3 In the embodiment shown, the collecting portion 21 of the present invention is, for example, a recessed portion 21', which is used to receive the residue from the accommodating cavity 11; preferably, in the first position, the recessed portion 21' can abut against the insertion end 01 of the aerosol generating article 00. More preferably, the recessed portion 21' can deform the insertion end, such as Figure 8 As shown; that is, when the aerosol generating product 00 is inserted into the accommodating cavity 11 until it abuts against the inner wall of the recessed portion 21', the recessed portion 21' applies an external force to the insertion end 01 of the aerosol generating product, so that the insertion end 01 is squeezed and deformed, and then at least a part of the insertion end 01 is compacted, which can not only effectively fix the aerosol generating product 00 in an appropriate position in the accommodating cavity 11 and prevent the insertion end 01 of the aerosol generating product from excessively protruding from the second opening 112, but also prevent and / or reduce the residue of the atomizable substance of the aerosol generating product 00 (such as tobacco residue) from falling, thereby avoiding the generation of end residue at the insertion end, while the residue is also completely received by the recessed portion 21', and also avoiding contamination of the inner wall of the accommodating cavity 11, which is conducive to further solving the cleaning problem of the heated smoking device. Among them, the part of the recessed portion 21' of the present invention that abuts against the insertion end 01 of the aerosol generating product includes the part that is axially (for example Figure 1-5 The x-direction shown) is at an angle (e.g. Figure 8 The angle β in the figure is preferably 20° to 70°, so that the airflow can enter the aerosol generating product 00 while the insertion end 01 is squeezed and deformed, thereby ensuring that the user has appropriate inhalation resistance; 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 recessed portion 21' to provide a portion that abuts against the insertion end 01 of the aerosol generating product.

[0054] exist Figure 2 and Figure 3In the embodiment shown, the second body 2 and the first body 1 are movably connected by magnetic connection, so that the first body 1 and the second body 2 can be detachably connected. As a result, the second body 2 and the first body 1 can be easily detachably connected. The magnetic connection is actually a suction-pull connection, that is, when an external force is applied to the aerosol generating device 0, it can be disassembled into two independent modules (such as the second body 2 and the first body 1) of the second body 2 and the first body 1. Figure 2 As shown in the figure, the two independent modules of the second body 2 and the first body 1 can be connected again to form an aerosol generating device 0 through magnetic attraction. The magnetic connection not only ensures the stability of the connection, but also provides a convenient disassembly method. The user can quickly separate the first body 1 and the second body 2 for cleaning and maintenance, which greatly improves the operability and ease of use of the device. In addition, the magnetic connection avoids complex mechanical structures, reduces failure points, and prolongs the service life of the device.

[0055] Specifically, refer to Figure 3 As shown, in this embodiment, two first magnet blocks 141, 142 are disposed in the first body 1, and the two first magnet blocks 141, 142 are arranged along a first direction (such as Figure 2-Figure 6 The two first magnet blocks 141 and 142 are respectively arranged on both sides of the second butt joint end 12, and are fixedly connected to the inner wall of the second butt joint end 12. Figure 2-Figure 6 The y direction shown) is perpendicular to the axial direction (e.g. Figure 1-5 The x direction shown in FIG. 1 ), that is, the first direction (such as Figure 2-Figure 6 The y direction shown in FIG. 1 is the length direction of the aerosol generating device 0 in the embodiment. Two second magnet blocks 231 and 232 are also correspondingly arranged in the second body 2. The two second magnet blocks 231 and 232 are arranged along the first direction (such as Figure 2-Figure 6 The two second magnet blocks 231 and 232 are fixedly connected to the inner wall of the first butt end 22, and the two first magnet blocks 141 and 142 and the two second magnet blocks 231 and 232 are axially (for example, Figure 1-5The first and second magnet blocks 141 and 142 are arranged relative to each other in the x direction shown in the figure. 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 body 2 and the first body 1 are connected. In addition, the first magnet blocks 141 and 142 are arranged in the first body 1, and the second magnet blocks 231 and 232 are arranged in the second body 2, and are not exposed to the outside of the shells of the first and second bodies 1 and 2, so that the user does not need to consider the impact on the first magnet blocks 141, 142 and the second magnet blocks 231 and 232 when cleaning the smoking utensils, which is also conducive to improving the stability of the use of magnetic connection. As a result, the user can easily disassemble the first body 1 and the second body 2 to better clean the smoking utensils. In some possible embodiments provided by the present invention, the present invention does not limit the specific magnetic field strength of the first magnet blocks 141, 142 or the second magnet blocks 231 and 232.

[0056] refer to Figure 4 and Figure 6 As shown, in this embodiment, the movable connection between the second body 2 and the first body 1 is a hinge, and the first body 1 can be flipped relative to the second body 2 through the hinge. That is to say, the user only needs to flip the first body 1 to expose the collecting part 21, and then clean the smoking device, which brings a more convenient and reliable use experience to the user.

[0057] Specifically, in some possible embodiments provided by the present invention, the hinged connection is a flip-top connection, and the first butt end 22 is connected along the second direction (eg Figure 4 and Figure 6 The z direction shown in FIG. 1 is a direction along which the second butt end 12 corresponds to the second direction (as shown in FIG. Figure 4 and Figure 6 The same side of the hinge 16 (as shown in the z direction) is connected by the hinge part 16, thereby realizing the hinge connection between the second body 2 and the first body 1, so that the first body 1 can be turned relative to the second body 2 with the axis of the hinge part 16 as the rotation axis, and the position of the first body 1 changes, so that the collecting part 21 is at least partially or completely exposed. Specifically, the hinge part 16 includes, for example, a hinge, a pin, a pin hole, etc., which can realize the hinged structure. Among them, the second direction (as shown in the z direction) is connected by the hinge part 16, thereby realizing the hinge connection between the second body 2 and the first body 1. Figure 4 and Figure 6 The z direction shown) is perpendicular to the axial direction (eg Figure 1-5 x direction as shown), and axial direction (e.g. Figure 1-5 x direction as shown), the first direction (as shown Figure 2-Figure 6 y direction as shown), the second direction (as shown Figure 4 and Figure 6 The z direction shown in FIG. 1 intersects each other, that is, the second direction (such as Figure 4 and Figure 6 The z direction shown in FIG. 4 is the width direction of the aerosol generating device 0 in the embodiment.

[0058] refer to Figure 5 As shown, in this embodiment, the first body 1 of the present invention is connected to the second body 2 via a rotating shaft 15, the rotating shaft 15 is perpendicular to the first docking end 22, and the first body 1 can rotate relative to the second body 2 along the rotating shaft 15, that is, the connection between the first body 1 and the second body 2 is a rotating connection. Therefore, the user can adjust the position of the first body 1 through a simple rotating action, so that the collecting part 21 is exposed, which is convenient for cleaning, maintenance, inspection or replacement of internal components. And the connection method of the rotating shaft 15 improves the stability and accuracy of the operation, while helping to maintain the compactness of the device, and improving the overall operational convenience and user experience.

[0059] Specifically, in some possible embodiments provided by the present invention, the first butt end 22 is disposed along a first direction (eg Figure 2-Figure 6 The y direction shown in FIG. 1 ) and the second butt end 12 correspond to one side along the first direction (as shown in FIG. Figure 2-Figure 6 The first body 2 and the first body 1 are connected on the same side of the rotating shaft 15 (in the y direction shown in the figure), thereby realizing that the second body 2 and the first body 1 are connected through the rotating shaft 16, so that the first body 1 takes the axis where the rotating shaft 15 is located as the rotation axis, and the first body 1 can rotate clockwise or counterclockwise relative to the second body 2. The positions of the first body 1 and the second body 2 are relatively staggered, so that the collecting part 21 is at least partially or completely exposed. Further, the rotating shaft 16 includes an axis and an axis seat, and the first butt end 22 and the second butt end 12 are connected along the first direction (as shown in the figure). Figure 2-Figure 6 A shaft seat is provided on each side of the y direction shown in the figure, and the two shaft seats are arranged along the axial direction (for example Figure 1-5 The two ends of the shaft are respectively inserted and connected with two shaft seats, so that the second body 2 and the first body 1 are connected through the rotating shaft 16.

[0060] Further, continue to refer to Figure 1 As shown, there is a gap 102 between the first body 1 and the second body 2, and the aerosol generating device 0 takes in air through the gap 102. In other words, the gap 102 is the air inlet channel of the aerosol generating device 0, and the external air enters the interior of the accommodating chamber 11 through the gap 102. As a result, the structure of the aerosol generating device 0 is simplified, no additional air path design is required, and good airflow distribution is guaranteed. The air inlet channel is located between the first docking end 22 and the second docking end 12, and the second body 2 and the first body 1 are movably connected, so that the user can clean the air inlet channel while cleaning the residue, which is conducive to further enhancing the user's suction experience.

[0061] Preferably, the accommodation cavity 11 of the present invention is axially (for example Figure 1-5 More preferably, the accommodating cavity 11 is axially (eg, Figure 1-5 The x direction shown in the figure is a straight-through structure with equal diameters, thereby avoiding the cleaning dead corners caused by the complex cavity structure, making it easy to discharge the residues, preventing the accumulation of residues, reducing the difficulty of maintenance, and being more conducive to cleaning. It can reduce the dirt and condensate inside the smoking device and the breeding of bacteria, making it more hygienic and healthy. When heating the aerosol generating product 00, the accommodating cavity 11 with equal diameter straight-through structure is conducive to providing a uniform airflow channel, reducing the airflow resistance, ensuring the stability of the aerosol generating process, and also conducive to ensuring the long-term stable operation and excellent performance of the aerosol generating device.

[0062] Furthermore, in this embodiment, the recessed portion 21' is axially (eg Figure 1-5 The depth of the recessed portion 21' is 1 to 2 mm in the x direction shown. Setting the depth of the recessed portion 21' to the above range ensures that the recessed portion 21' can effectively contain residues from the inside of the accommodating cavity 11, such as end threads, condensed liquid, etc., to prevent them from spreading to other parts. It is also convenient to use tools to perform thorough cleaning, reduce cleaning dead corners, improve cleaning efficiency, make the cleaning process more convenient, and reduce maintenance costs; in addition, it can assist the equal-diameter straight-through accommodating cavity 11 in limiting the aerosol-generating product 00, especially the recessed portion 21' that deviates from the center line of the accommodating cavity 11.

[0063] In some possible embodiments provided by the present invention, Figure 7 As shown, the aerosol generating device 0 further includes two waterproof covers 3, and the two waterproof covers 3 respectively cover the first body 1 along the axial direction (for example Figure 1-5 At this time, the user can also wash the smoking device by water, which is more convenient and has a better washing effect. Specifically, the shape of the waterproof cover 3 is similar to that of the first body 1 in the axial direction (for example, Figure 1-5 The shapes of the two end faces of the first body 1 (in the x direction shown in the figure) are the same, one of the end faces is, for example, the second docking end 12, that is, 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 cover the two end faces accordingly. A silicone ring 31 may 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 improving the reliability of the long-term stable operation of the aerosol generating device. Similarly, the second body 2 may also be provided with a waterproof cover 3, that is, the shape of the waterproof cover 3 is also the same as the shape of the first docking end 22, so as to seal the first docking end 22, and then the user can also clean the second body 2 by washing with water. Furthermore, a silicone ring 31 may be provided between the waterproof cover 3 and the second body 2, which will not be repeated here. Therefore, through the above-mentioned arrangement, 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 invention, the first body 1 includes a heating element 13, and the heating element 13 is arranged on the periphery of the accommodating cavity 11 or defines the accommodating cavity 11. Thus, the problem of uneven heating of the aerosol generating product 00 is reduced by providing uniform heat distribution through the heating element 11, and the quality of the generated aerosol is improved. Among them, the heating element 13 defines the accommodating cavity 11, that is, at least a part of the heating element 13 forms at least a part of the accommodating cavity 11, that is, at least a part of the heating element 13 also serves as at least a part of the accommodating cavity 11. The heating method of the present invention includes but is not limited to electromagnetic heating, resistance heating or infrared heating. For the electromagnetic heating method, the sensor serves as the heating element 13, which defines the accommodating cavity 11. Further, the first body 1 also includes a shell 10, and the accommodating cavity 11 is sealed and connected to the shell 10. Through the matching sealing arrangement, it is easier 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. The heating element 13 only needs to be dried after water washing, and it can continue to be used, and the reliability of the use of the aerosol generating device 0 is also guaranteed.

[0065] Preferably, the heating element 13 is sleeved on the periphery of the receiving cavity 11, avoiding direct contact between the heating component and the tobacco product, and the user does not need to worry about whether the heating element will be damaged when cleaning the receiving cavity 11 of the smoking device. Therefore, while ensuring efficient heating, the cleaning and maintenance experience is also optimized, enhancing the reliability of the device and user satisfaction. For example, refer to Figure 3 As shown, in the embodiment of the present invention, the heating element 13 of the present invention is a heating tube, and the heating tube is sleeved on the outer periphery of the accommodating cavity 11.

[0066] Furthermore, the heating element 13 is arranged along the axial direction (eg Figure 1-5 The two ends of the first body 1 are respectively connected to the first body 1 along the axial direction (for example Figure 1-5 The two ends of the aerosol generating product 00 are 2 to 3 mm apart in the x direction shown. The above arrangement prevents the downstream end of the aerosol generating product 00 from being too hot, which causes the user to have a bad smoking experience. On the other hand, it prevents the user from being burned by the excessive temperature of the collection part 21 when it is exposed, which helps the user to clean the smoking device safely.

[0067] In some possible embodiments provided by the present invention, Figure 3 Combination Figure 6 As shown, the first body 1 has a second docking end 12, the second docking end 12 is provided with first conductive electrodes 121, 122, the first docking end 22 is provided with second conductive electrodes 221, 222, when the second body 2 is docked with the first body 1, the first conductive electrodes 121, 122 and the second conductive electrodes 221, 222 are in contact and conduction. Preferably, the first conductive electrodes 121, 122 and the second conductive electrodes 221, 222 are axially (e.g. Figure 1-5In other words, the second butt end 12 is provided with a first conductive electrode 121, 122, and the first butt end 22 is arranged along the axial direction (eg Figure 1-5 The second conductive electrodes 221 and 222 are correspondingly provided in the x direction as shown in the figure. Furthermore, when the second body 2 is connected to the first body 1, the first conductive electrodes 121 and 122 and the second conductive electrodes 221 and 222 are in contact and conduction, so as 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 position thereof changes relatively, the first conductive electrodes 121 and 122 and the second conductive electrodes 221 and 222 may not be in contact and conduction, so as to realize the circuit disconnection between the first body 1 and the second body 2.

[0068] By the above arrangement, the electrical connection or circuit disconnection of the first body 1 and the second body 2 is realized, the circuit connection structure of the smoking device is simplified, and the first body 1 and the second body 2 are quickly and stably electrically connected. At the same time, when the second body 2 is separated from the first body 1 or the position changes relatively, the circuit disconnection can be conveniently realized. On the one hand, it can prevent the first body 1 from being continuously heated to the point of dry burning, excessive temperature damaging the smoking device or scalding the user when the first body 1 and the second body 2 are accidentally separated or the position changes relatively; on the other hand, the user does not need to worry about accidents such as electric shock when directly cleaning the smoking device due to forgetting to turn off the circuit of the smoking device. In addition, the electrical connection method of the above arrangement also reduces the use of cables and connectors, avoids complex internal circuit layout, and reduces potential fault points. Furthermore, the dead angle when cleaning the smoking device is correspondingly reduced, making the cleaning work more thorough. Therefore, the arrangement 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 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 invention are disposed in the first body 1 and along a first direction (eg Figure 2-Figure 6 The first conductive electrodes 121 and 122 are respectively disposed on both sides of the second butting end 12, and at least a portion of the first conductive electrodes 121 and 122 is axially (eg Figure 1-5 The second conductive electrodes 221, 222 are disposed in the second body 2 and extend along the first direction (as shown in the x direction) from the second butt end 12. Figure 2-Figure 6 The second conductive electrodes 221 and 222 are respectively disposed on both sides of the first butting end 22, and at least a portion of the second conductive electrodes 221 and 222 is axially (eg Figure 1-5 The x direction shown in the figure protrudes from the first butt 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 embodiments, the second body 2 of the present invention includes a circuit board and a battery 25, and the circuit board and the 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 are in contact with the second conductive electrodes 221 and 222, thereby realizing the 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. Among them, 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 the detection of heating circuit failure. Further, in order to avoid the conductive liquid used in cleaning the smoking device causing the second conductive electrodes 221 and 222 to contact with the conductive liquid and 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, and the connection signal may include current, voltage, power, etc. Then, it is determined whether the connection signal is caused by the electrical connection between the first body 1 and the second body 2, or the connection signal is caused by other unexpected events. If the connection signal is caused by the electrical connection between the first body 1 and the second body 2, the smoking device works normally; if the connection signal is caused by an unexpected event, the smoking device does not work. The charging circuit board 26 is used to control the charging and discharging of the battery 25 and the battery status detection, and the battery status includes overheating, etc.

[0071] The present invention provides an aerosol generating system, comprising an aerosol generating device 0 and an aerosol generating article 00 in any one 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 difficulty of maintenance, and extending the service life of the aerosol generating device 0.

[0073] In summary, the present invention adopts a modular design concept, specifically, the entire aerosol generating device 0 is divided into two modules of a first main body 1 and a second main body 2 along the axial direction, the first main body 1 may include a housing chamber 11, a heating element 13, first magnet blocks 141, 142, and first conductive electrodes 121, 122, wherein the shell of the first main body 1 may be made of heat-insulating materials to improve the comfort of the user. The second main body 2 may include a collecting part 21, second magnet blocks 231, 232, second conductive electrodes 221, 222, a circuit board, and a battery 25. Furthermore, the mutual cooperation of the components of the first main body 1 and the second main body 2 ensures the efficiency and safety of the process of heating the smoking device to generate aerosol. Among them, the housing chamber 11 adopts a through-type design from top to bottom, and the generated condensate and tobacco residue are better accommodated by the recessed part 21' (i.e., the collecting part 21) of the second main body 2. With the setting of the movable connection between the first main body 1 and the second main body 2, the user can conveniently and simply clean the smoking device. Furthermore, the first body 1 and the second body 2 can realize electrical communication or circuit disconnection through the electrode conductive sheet, which improves the safety of users and the convenience of cleaning the smoking device, and further completely solves the cleaning problem of the smoking device.
