[0058] In some embodiments, the aerosol generating substrate comprises nicotine. The nicotine can comprise nicotine or nicotine salt. Nicotine has a nerve stimulating effect and is used to bring the user a sense of smoking. The first aerosol generated by the first aerosol generating substrate contains nicotine.

[0059] In some embodiments, the aerosol generating substrate comprises a flavoring agent for stimulating the olfactory of the user to provide a fragrance or for stimulating the taste of the user to adjust the taste.

[0060] The flavoring agent can comprise a cooling agent. The cooling agent can make the aerosol refreshing and cool, which helps to enhance the throat moistening effect. The cooling agent can comprise at least one of N,2,3-trimethyl-2-isopropylbutanamide (WS-23), menthol, peppermint oil, and N-ethyl-p-menthyl-3-carboxamide (WS-3).

[0062] The flavoring agent can include a tobacco extract.

[0066] In some embodiments, the first accommodation cavity 311 is configured to store a first aerosol-generating substrate, and the second accommodation cavity 321 is configured to store a second aerosol-generating substrate, so that the first atomizer 31 can generate a first aerosol, and the second atomizer 32 can generate a second aerosol. As an example, the first aerosol-generating substrate and the second aerosol-generating substrate include different components, so that the first aerosol and the second aerosol have different tastes; for example, the first aerosol-generating substrate includes nicotine but does not include a flavoring agent, and the second aerosol-generating substrate includes a flavoring agent; or the first aerosol-generating substrate and the second aerosol-generating substrate include different flavoring agents. As an example, the first aerosol-generating substrate and the second aerosol-generating substrate include components in different proportions, so that the first aerosol and the second aerosol have different tastes; for example, the first aerosol-generating substrate and the second aerosol-generating substrate both include a cooling agent, but the concentrations of the cooling agents are different, so that the cooling taste of the first aerosol and the cooling taste of the second aerosol are different.

[0067] In some embodiments, the first aerosol generating substrate can include a first liquid substrate. Based on this, the first atomizing member 312 can include a first liquid absorbing element and a first heating element disposed on the first liquid absorbing element. The first liquid absorbing element can be a porous body for guiding the first liquid substrate into an atomization range of the heating element.

[0071] In some embodiments, reference can be made to Figure 2, at least a portion of the first atomization member 312 is disposed in the third air conduit 313. In other embodiments, not shown, the first atomizer further comprises a first compartment, the first atomization member is disposed in the first compartment, the first compartment is in communication with the first holding chamber through a liquid passage, such that the first liquid substrate in the first holding chamber can be delivered to the first atomization member, and the first compartment is in fluid communication with the third air conduit, so that the aerosol formed in the first compartment can be guided out by the third air conduit.

In other embodiments, not shown, the second atomizer further comprises a second compartment, the second atomization member is disposed in the second compartment, the second compartment is in communication with the second holding chamber through a liquid passage, such that the second liquid substrate in the second holding chamber can be delivered to the second atomization member, and the second compartment is in fluid communication with the fourth air conduit, so that the aerosol formed in the second compartment can be guided out by the fourth air conduit.

[0073] In some embodiments, reference can be made to Figure 2 , the first atomizer 31 further comprises a first liquid storage element 314, the first liquid storage element 314 has a large number of pores capable of adsorbing a large amount of the first liquid substrate. The first liquid storage element 314 is disposed in the first holding chamber 311, at least a portion of the first liquid substrate stored in the first holding chamber 311 is retained in the first liquid storage element 314, so as to prevent the first liquid substrate from leaking from the first holding chamber 311.

[0074] The liquid storage element includes, but is not limited to, one of the following materials: cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, porous ceramic material, high molecular fiber, or various combinations of the above materials.

[0075] In some embodiments, reference can be made to Figure 2 , the reserve module 2 comprises a first reserve bin 21 and a second reserve bin 22 which are separately arranged, and the first reserve bin 21 and the second reserve bin 22 are both used for storing the aerosol generating substrate.

[0076] The aerosol generating substrate stored in the first reserve tank 21 can be the same as the aerosol generating substrate stored in the second reserve tank 22. Alternatively, the first reserve tank 21 can be configured to store a first aerosol generating substrate, and the second reserve tank 22 can be configured to store a second aerosol generating substrate.

[0077] The reserve module 2 can be connected with the atomization module 3. When the reserve module 2 is connected with the atomization module 3, a fluid channel is established between the first reserve tank 21 and the first containing cavity 311, so that the first reserve tank 21 can be in fluid communication with the first containing cavity 311, thereby the first reserve tank 21 can supplement the first containing cavity 311 with the aerosol generating substrate, so as to prolong the use time of the first atomization member 312 and prolong the total time of the first atomizer 31 generating aerosols.

[0078] Preferably, the capacity of the first reserve tank 21 is greater than the capacity of the first containing cavity 311. For example, the first reserve tank 21 can contain 5ML of the first liquid substrate, and the first containing cavity 311 can contain 1ML of the first liquid substrate.

[0079] When the reserve module 2 is connected with the atomization module 3, a fluid channel is established between the second reserve tank 22 and the second containing cavity 321, so that the second reserve tank 22 can be in fluid communication with the second containing cavity 321, thereby the second reserve tank 22 can supplement the second containing cavity 321 with the aerosol generating substrate, so as to prolong the use time of the second atomization member 322 and prolong the total time of the second atomizer 32 generating aerosols.

[0080] Preferably, the capacity of the second reserve tank 22 is greater than the capacity of the second containing cavity 321. For example, the second reserve tank 22 can contain 5ML of the second liquid substrate, and the second containing cavity 321 can contain 1ML of the second liquid substrate.

[0081] In some embodiments, the sum Q1 of the capacity of the first reserve tank 21 and the capacity of the second reserve tank 22 satisfies: 2ML≤Q1≤10ML. Of course, Q1 can also be greater than 10ML. Wherein, the capacity of the first reserve tank 21 can be the same as the capacity of the second reserve tank 22, of course, the capacity of the first reserve tank 21 can also be different from the capacity of the second reserve tank 22.

[0082] In some embodiments, the sum Q2 of the capacity of the first containing cavity 311 and the capacity of the second containing cavity 321 satisfies: 0ML

[0083] In some embodiments, reference can be made to Figure 2When the reserve module 2 is connected with the atomization module 3, at least two first fluid channels 231 are formed between the first reserve bin 21 and the first containing cavity 311, and the first reserve bin 21 and the first containing cavity 311 are in fluid communication through the at least two first fluid channels 231, so that the air pressure between the first reserve bin 21 and the first containing cavity 311 can achieve dynamic balance. Thus, when the amount of aerosol generating substrate in the first containing cavity 311 decreases, causing the air pressure of the first containing cavity 311 to decrease, the first reserve bin 21 can automatically inject aerosol generating substrate into the first containing cavity 311 under the action of the air pressure difference between the first reserve bin 21 and the first containing cavity 311; when the amount of aerosol generating substrate in the first containing cavity 311 is relatively stable, the first reserve bin 21 can automatically stop injecting aerosol generating substrate into the first containing cavity 311 based on the air pressure balance between the first reserve bin 21 and the first containing cavity 311. The speed at which the first reserve bin 21 supplies aerosol generating substrate to the first containing cavity 311 can be positively correlated with the consumption speed of the aerosol generating substrate in the first containing cavity 311.

[0084] More specifically, reference can be made to Figures 2-4 The reserve module 2 includes a first base 241 arranged at the end of the first reserve bin 21, and at least two first flow guide columns 251 are arranged on the first base 241. At least a part of the first fluid channel 231 that fluidly connects the first containing cavity 311 and the first reserve bin 21 is arranged inside the first flow guide column 251. The first flow guide column 251 is connected with the atomization module 3. More specifically, the first atomizer 31 includes a first sealing plug 331 for sealing at least part of the boundary of the first containing cavity 311, and a plurality of first docking holes 3311 are arranged on the first sealing plug 331. When the reserve module 2 is connected with the atomization module 3, at least a part of the plurality of first flow guide columns 251 are fitted in the plurality of first docking holes 3311 in interference.

[0085] Further, the first flow guide column 251 is provided with a first flow guide outlet 2511 for guiding the aerosol generating substrate in the first fluid channel 231 out of the first flow guide column 251. When the reserve module 2 is connected to the atomization module 3, at least a part of the reserve module 2 is movable relative to the atomization module 3 between a first position and a second position. When at least a part of the reserve module 2 is located at the first position, the first flow guide outlet 2511 is located in the first sealing plug 331, so that the first flow guide outlet 2511 is sealed, and the first fluid channel 231 between the first containing cavity 311 and the first reserve chamber 21 is thus disconnected. When at least a part of the reserve module 2 is located at the second position, the first flow guide outlet 2511 is located outside the sealing range of the first sealing plug 331, so that the first flow guide outlet 2511 is in fluid communication with the first containing cavity 311, and the first fluid channel 231 between the first containing cavity 311 and the first reserve chamber 21 is thus connected. Preferably, the first flow guide outlet 2511 is arranged on the side of the first flow guide column 251.

[0086] In some embodiments, at least a part of the reserve module 2 is movable relative to the atomization module 3 between a first position and a second position, so that when the aerosol generating device is temporarily not needed to be used, for example, when the aerosol generating device is charging, or when the user is sleeping, at least a part of the reserve module 2 is located at the first position, so that the first fluid channel 231 between the first containing cavity 311 and the first reserve chamber 21 is disconnected, to prevent the aerosol generating substrate in the first containing cavity 311 from leaking due to excessive saturation. Of course, at least a part of the reserve module 2 can also be configured to be unidirectionally movable from the first position to the second position relative to the atomization module 3.

[0087] Similarly, in some embodiments, at least a part of the reserve module 2 is movable relative to the atomization module 3 between a first position and a second position, so that when the aerosol generating device is temporarily not needed to be used, for example, when the aerosol generating device is charging, or when the user is sleeping, at least a part of the reserve module 2 is located at the first position, so that the second fluid channel 232 between the second reserve chamber 22 and the second containing cavity 321 is disconnected, to prevent the aerosol generating substrate in the second containing cavity 321 from leaking due to excessive saturation. Of course, at least a part of the reserve module 2 can also be configured to be unidirectionally movable from the first position to the second position relative to the atomization module 3. Figure 2 Figure 3 In some embodiments, when the reserve module 2 is connected to the atomization module 3, at least two independent second fluid channels 232 are formed between the second reserve chamber 22 and the second containing cavity 321, and the second reserve chamber 22 and the second containing cavity 321 are in fluid communication through the at least two independent second fluid channels 232, so that the air pressure between the second reserve chamber 22 and the second containing cavity 321 can be dynamically balanced. In some embodiments, the speed of the aerosol generating substrate supplied from the second reserve chamber 22 to the second containing cavity 321 is positively correlated with the consumption speed of the aerosol generating substrate in the second containing cavity 321.

[0088] More specifically, at least a part of the reserve module 2 is movable relative to the atomization module 3 between a first position and a second position, so that when the aerosol generating device is temporarily not needed to be used, for example, when the aerosol generating device is charging, or when the user is sleeping, at least a part of the reserve module 2 is located at the first position, so that the second fluid channel 232 between the second reserve chamber 22 and the second containing cavity 321 is disconnected, to prevent the aerosol generating substrate in the second containing cavity 321 from leaking due to excessive saturation. Of course, at least a part of the reserve module 2 can also be configured to be unidirectionally movable from the first position to the second position relative to the atomization module 3. Figures 2-4 ​The reserve module 2 comprises a second base 242 arranged at an end of the second reserve chamber 22, and the second base 242 is provided with at least two second flow guide columns 252, and at least a part of the second fluid passage 232, which fluidly connects the second containing cavity 321 and the second reserve chamber 22, is arranged inside the second flow guide column 252. The second flow guide column 252 is connected with the atomization module 3. More specifically, the second atomizer 32 comprises a second sealing plug 332 for sealing at least a part of the boundary of the second containing cavity 321, and the second sealing plug 332 is provided with a plurality of second docking holes 3321, and when the reserve module 2 is connected with the atomization module 3, at least a part of the plurality of second flow guide columns 252 are embedded in the plurality of second docking holes 3321 in a one-to-one correspondence and with interference. The first base 241 and the second base 242 can be integrally formed, or the first base 241 and the second base 242 can be connected with each other. Of course, the first base 241 and the second base 242 can also be arranged in a spaced manner. Similarly, the first sealing plug 331 and the second sealing plug 332 can be integrally formed, or the first sealing plug 331 and the second sealing plug 332 can be connected with each other. Of course, the first sealing plug 331 and the second sealing plug 332 can also be arranged in a spaced manner.

[0089] Further, the second flow guide column 252 is provided with a second flow guide outlet 2521 for guiding the aerosol generating substrate in the second fluid passage 232, and at least a part of the reserve module 2 is movable relative to the atomization module 3 between the first position and the second position when the reserve module 2 is connected with the atomization module 3. When at least a part of the reserve module 2 is located at the first position, the second flow guide outlet 2521 is located in the second sealing plug 332, so that the second flow guide outlet 2521 is sealed, and the second fluid passage 232 between the second containing cavity 321 and the second reserve chamber 22 is thus disconnected; when at least a part of the reserve module 2 is located at the second position, the second flow guide outlet 2521 is located outside the sealing range of the second sealing plug 332, so that the second flow guide outlet 2521 is in fluid communication with the second containing cavity 321, and the second fluid passage 232 between the second containing cavity 321 and the second reserve chamber 22 is thus connected. Preferably, the second flow guide outlet 2521 is arranged on the side of the second flow guide column 252.

[0090] At least a part of the reserve module 2 is movable relative to the atomization module 3 between the first position and the second position. Of course, at least a part of the reserve module 2 can also be configured to be unidirectionally movable from the first position to the second position relative to the atomization module 3.

[0091] Further, when the reserve module 2 is at least partially located in the first position, the first flow outlet 2511 is sealed by the first sealing plug 331, so that the first fluid channel 231 between the first storage chamber 21 and the first containing cavity 311 is disconnected, while the second flow outlet 2521 is sealed by the second sealing plug 332, so that the second fluid channel 232 between the second storage chamber 22 and the second containing cavity 321 is disconnected; when the reserve module 2 is at least partially located in the second position, the first flow outlet 2511 is located outside the sealing range of the first sealing plug 331, so that the first fluid channel 231 between the first storage chamber 21 and the first containing cavity 311 is connected, while the second flow outlet 2521 is located outside the sealing range of the second sealing plug 332, so that the second fluid channel 232 between the second storage chamber 22 and the second containing cavity 321 is connected.

[0092] In other words, the first fluid channel 231 between the first storage chamber 21 and the first containing cavity 311 and the second fluid channel 232 between the second storage chamber 22 and the second containing cavity 321 can be simultaneously connected or disconnected by one operation.

[0093] In other embodiments, the reserve module 2 comprises a first part and a second part which can be driven independently, the first part is arranged in linkage with the first storage chamber 21, and the second part is arranged in linkage with the second storage chamber 22. The first fluid channel 231 between the first storage chamber 21 and the first containing cavity 311 can be disconnected or connected independently by driving the first part; the second fluid channel 232 between the second storage chamber 22 and the second containing cavity 321 can be disconnected or connected independently by driving the second part.

[0094] In other embodiments, the first atomizer 31 and the second atomizer 32 are arranged independently of each other, the first atomizer 31 and the second atomizer 32 can be connected to the reserve module 2 independently of each other, and the first atomizer 31 can be driven independently, so that the first fluid channel 231 between the first storage chamber 21 and the first containing cavity 311 can be disconnected or connected independently; the second atomizer 32 can also be driven independently, so that the second fluid channel 232 between the second storage chamber 22 and the second containing cavity 321 can also be disconnected or connected independently.

[0095] In some embodiments, the first atomizer 31 and the second atomizer 32 are independently arranged. The first atomizer 31 and the second atomizer 32 can be combined into one whole, and then the whole is connected with the storage module 2. For example, the atomization module 3 further comprises a housing, and the first atomizer 31 and the second atomizer 32 are arranged side by side in the housing, so that the relative position between the first atomizer 31 and the second atomizer 32 is determined by the housing, and the first atomizer 31 and the second atomizer 32 are combined with each other. Alternatively, for example, the first atomizer 31 and the second atomizer 32 are spliced or buckled with each other to form a whole.

[0096] Further, the whole formed by the first atomizer 31 and the second atomizer 32 is configured to be disassembled, so that the first atomizer 31 and the second atomizer 32 can be replaced separately.

[0097] Of course, in other embodiments, the first atomizer 31 and the second atomizer 32 can be connected with the storage module 2 respectively and independently. Alternatively, in other embodiments, the first atomizer 31 and the second atomizer 32 can share parts, and specifically, Figure 2 the atomization module 3 further comprises a housing, the housing defines part of the boundary of the first accommodating cavity 311 and part of the boundary of the second accommodating cavity 321, but the first atomization member 312 and the second atomization member 323 are independent of each other.

[0098] Referring to Figures 1-3 , the aerosol-generating device 100 further comprises a mouthpiece module 1 having an air inlet 11, at least part of the mouthpiece module 1 can be held by the user's lips, and when the user holds the mouthpiece module 1, the air inlet 11 is arranged towards the user's oral cavity. The user sucks the aerosol generated by the atomization module 3 by sucking the mouthpiece module 1.

[0099] In some embodiments, not shown, the aerosol-generating device comprises a plurality of mouthpiece modules, and the plurality of mouthpiece modules are connected with the plurality of atomizers one by one, so that the plurality of air inlets can be in fluid communication with the plurality of atomizers one by one.

[0100] In some embodiments, referring to Figure 2 , the number of mouthpiece modules 1 is less than the number of atomizers, and the first atomizer 31 and the second atomizer 32 share the same mouthpiece module 1.

[0101] In some embodiments, referring to Figure 2 , Figure 5 and Figure 6The first atomizing member 312 and the second atomizing member 322 are configured to be able to independently fluidly communicate with the air inlet 11. The first atomizer 31 and the second atomizer 32 belong to the same air flow level and are not in upstream and downstream relationship with each other in the air flow direction. Therefore, the aerosol generated by the first atomizer 31 can flow into the air inlet 11 downstream without passing through the second atomizer 32, and the aerosol generated by the second atomizer 32 can flow into the air inlet 11 downstream without passing through the first atomizer 31.

[0102] In some embodiments, the air inlet 11 is configured to selectively fluidly communicate with one of the first atomizing member 312 and the second atomizing member 322, so that the air paths between the first atomizing member 312 and the air inlet 11 and between the second atomizing member 322 and the air inlet 11 cannot be simultaneously conducted. Therefore, the first atomizer 31 and the second atomizer 32 cannot work at the same time or cannot generate aerosols at the same time. Thus, in some embodiments, the aerosol generating substrate in the first containing cavity 311 and the aerosol generating substrate in the second containing cavity 321 cannot be consumed at the same time, or the time when the first reserve tank 21 supplies the aerosol generating substrate to the first containing cavity 311 and the time when the second reserve tank 22 supplies the aerosol generating substrate to the second containing cavity 321 are staggered with each other. It should be noted that, in some embodiments, the first reserve tank 21 and the second reserve tank 22 are configured to supply the aerosol generating substrate to the first containing cavity 311 and the second containing cavity 321 at the same time. Figures 5-9 In the illustrated embodiments, the direction of fluid in the air path is indicated by a solid thin arrow, and the direction of fluid in the liquid path is indicated by a hollow thick arrow.

[0103] As a typical example, reference can be made to Figure 2 and Figure 5 The reserve module 2 further includes a first air guide pipe 261 for fluid communication with the first atomizing member 312 and a second air guide pipe 262 for fluid communication with the second atomizing member 322. The mouthpiece module 1 is connected to the reserve module 2, and the air inlet 11 is configured to selectively fluidly communicate with one of the first air guide pipe 261 and the second air guide pipe 262, so that the air paths between the first air guide pipe 261 and the air inlet 11 and between the second air guide pipe 262 and the air inlet 11 cannot be simultaneously conducted.

[0104] The first air guide pipe 261 is disposed upstream of the air inlet 11 and the first atomizer 31 or the third air guide pipe 313 in the air flow direction, so that when the air path between the first air guide pipe 261 and the air inlet 11 is conducted, the aerosol generated by the first atomizer 31 can flow into the air inlet 11 through the first air guide pipe 261, and when the air path between the first air guide pipe 261 and the air inlet 11 is disconnected, the air path between the first atomizing member 312 and the air inlet 11 is disconnected.

[0105] The second air guide tube 262 is arranged in the middle of the air flow direction between the air inlet 11 and the second atomizer 32 or the fourth air guide tube 323, so that when the air path between the second air guide tube 262 and the air inlet 11 is connected, the aerosol generated by the second atomizer 32 can flow into the air inlet 11 through the second air guide tube 262, and when the air path between the second air guide tube 262 and the air inlet 11 is disconnected, the air path between the second atomizing member 322 and the air inlet 11 is disconnected.

[0106] The first air guide tube 261 can pass through the first storage compartment 21, and of course the first air guide tube 261 can also be arranged outside the first storage compartment 21. The second air guide tube 262 can pass through the second storage compartment 22, and of course the second air guide tube 262 can also be arranged outside the second storage compartment 22.

[0107] The air inlet 11 can be selectively in fluid communication with one of the first air guide tube 261 and the second air guide tube 262 in various ways.

[0108] For example 1: the mouthpiece module 1 is rotationally connected with the storage module 2, so that the air inlet 11 is in fluid communication with one of the first air guide tube 261 and the second air guide tube 262 by rotation, and is isolated from the other.

[0109] More specifically, please refer to Figure 2 and Figure 3 The air inlet 11 is arranged at the proximal end of the mouthpiece module 1, and the mouthpiece module 1 further comprises an airway tube 12, a base 13 and a first rotation mechanism 14 arranged on the base 13. The proximal end of the airway tube 12 forms the air inlet 11, the distal end of the airway tube 12 is arranged towards the storage module 2, and the base 13 is arranged around the periphery of the airway tube 12. The storage module 2 further comprises a second rotation mechanism 27, and the first rotation mechanism 14 and the second rotation mechanism 27 are rotationally matched. When the mouthpiece module 1 rotates relative to the storage module 2, the mouthpiece module 1 or the storage module 2 rotates around the central axis of the first rotation mechanism 14 and / or the second rotation mechanism 27. Among them, one of the first rotation mechanism 14 and the second rotation mechanism 27 comprises a receiving hole, and the other comprises a rotation column, at least part of the rotation column is rotationally located in the receiving hole.

[0110] When the rotation angle of the mouthpiece module 1 is 0°, the distal end of the airway tube 12 is arranged corresponding to the first atomizer 31 and is in fluid communication with the first air guide tube 261 and the air inlet 11, and the blocking portion on the base 13 is arranged corresponding to the second air guide tube 262, so that the air path between the first air guide tube 261 and the air inlet 11 is connected, and the air path between the second air guide tube 262 and the air inlet 11 is disconnected.

[0111] When the rotation angle of the mouthpiece module 1 is θ, the distal end of the airway tube 12 is arranged corresponding to the second atomizer 32 and is in fluid communication with the second air guide tube 262 and the inhalation port 11, and the blocking portion on the base 13 is arranged corresponding to the first air guide tube 261, so that the air path between the first air guide tube 261 and the inhalation port 11 is disconnected, and the air path between the second air guide tube 262 and the inhalation port 11 is conducted. θ can be equal to 360° / N, N is the number of atomizers in the atomization module 3. For example, when the atomization module 3 includes only the first atomizer 31 and the second atomizer 32, θ can be 180°.

[0112] For example 2: The mouthpiece module 1 is configured to be detachably connected with the reserve module 2 along at least two azimuth angles, so that the inhalation port 11 is selectively in fluid communication with one of the first air guide tube 261 and the second air guide tube 262.

[0113] More specifically, when the mouthpiece module 1 is connected with the reserve module 2 along the first azimuth angle, the inhalation port 11 is in fluid communication with the first air guide tube 261, and when the mouthpiece module 1 is connected with the reserve module 2 along the second azimuth angle, the inhalation port 11 is in fluid communication with the second air guide tube 262.

[0114] Further, when the mouthpiece module 1 is connected with the reserve module 2 along the first azimuth angle, the airway tube 12 of the mouthpiece module 1 is arranged corresponding to the first atomizer 31 and is in fluid communication with the first air guide tube 261 and the inhalation port 11, and the blocking portion on the base 13 is arranged corresponding to the second air guide tube 262, so that the air path between the first air guide tube 261 and the inhalation port 11 is conducted, and the air path between the second air guide tube 262 and the inhalation port 11 is disconnected.

[0115] When it is needed to make the air path between the inhalation port 11 and the second air guide tube 262 conducted, the mouthpiece module 1 is first removed from the reserve module 2, and then the mouthpiece module 1 is connected with the reserve module 2 along the second azimuth angle, so that the distal end of the airway tube 12 is arranged corresponding to the second atomizer 32 and is in fluid communication with the second air guide tube 262 and the inhalation port 11, and the blocking portion on the base 13 is arranged corresponding to the first air guide tube 261, so that the air path between the first air guide tube 261 and the inhalation port 11 is disconnected, and the air path between the second air guide tube 262 and the inhalation port 11 is conducted. The phase difference between the first azimuth angle and the second azimuth angle is β, and β can be equal to 360° / N, N is the number of atomizers in the atomization module 3. For example, when the atomization module 3 includes only the first atomizer 31 and the second atomizer 32, β can be 180°.

[0116] In some embodiments, reference can be made to Figure 2, the suction nozzle module 1 includes a first magnetic member 15, and the reserve module 2 includes a second magnetic member 28, the first magnetic member 15 is configured to be magnetically attracted to the second magnetic member 28 when the suction port 11 is in fluid communication with the first air guide pipe 261 or the second air guide pipe 262. By magnetically attracting the first magnetic member 15 to the second magnetic member 28, it is prevented that the suction nozzle module 1 is rotated relative to the reserve module 2 in an unexpected manner, or is removed from the reserve module 2 in an unexpected manner, thereby facilitating the suction port 11 to remain in fluid communication with the first air guide pipe 261 or the second air guide pipe 262. Meanwhile, the magnetic attraction between the first magnetic member 15 and the second magnetic member 28 can cause the distal end of the airway tube 12 to tightly fit with the reserve module 2, so as to prevent aerosol from leaking from the distal end of the airway tube 12.

[0117] The first magnetic member 15 and the second magnetic member 28 can each have a plurality, and when the suction port 11 is in fluid communication with the first air guide pipe 261 or the second air guide pipe 262, the plurality of first magnetic members 15 and the plurality of second magnetic members 28 can be magnetically attracted to each other in a one-to-one correspondence.

[0118] In some embodiments, the first magnetic member 15 and the second magnetic member 28 can be configured to be magnetically attracted to each other when the suction port 11 is in fluid communication with the first air guide pipe 261 or the second air guide pipe 262. Figure 2 and Figure 3 The aerosol-generating device 100 further includes a porous fiber 4 disposed between the suction nozzle module 1 and the reserve module 2, the porous fiber 4 being configured to adsorb aerosol flowing from the first air guide pipe 261 or the second air guide pipe 262 during rotation of the suction nozzle module 1 relative to the reserve module 2, or after the suction nozzle module 1 is removed from the reserve module 2, or the porous fiber 4 being configured to adsorb condensate formed by condensation of aerosol between the suction nozzle module 1 and the reserve module 2. The porous fiber 4 can be retained in the suction nozzle module 1.

[0119] For example, the aerosol-generating device 100 can include a first adjustment element (not shown) that is movable relative to the reserve module 2 between a third position and a fourth position, the air path between the suction port 11 and the first air guide pipe 261 being open when the first adjustment element is in the third position, and the air path between the suction port 11 and the first air guide pipe 261 being closed when the first adjustment element is in the fourth position.

[0120] Further, the air path between the suction port 11 and the second air guide pipe 262 is open when the first adjustment element is in the third position, and the air path between the suction port 11 and the second air guide pipe 262 is closed when the first adjustment element is in the fourth position.

[0121] The air path between the first atomizer 31 and the first air guide pipe 261 can be opened or closed in various ways, thereby opening or closing the air path between the suction port 11 and the first atomizer 31.

[0122] For example, the aerosol-generating device 100 can include a second adjustment element (not shown) that is movable relative to the reserve module 2 between a fifth position and a sixth position. When the second adjustment element is in the fifth position, the air path between the first air guide 261 and the third air guide 313 is disconnected. When the second adjustment element is in the sixth position, the air path between the first air guide 261 and the third air guide 313 is connected.

[0123] Similarly, the air path between the second atomizer 32 and the second air guide 262 can be connected or disconnected in various ways, thereby achieving the connection or disconnection of the air path between the suction port 11 and the second atomizer 32.

[0124] For example, when the second adjustment element is in the fifth position, the air path between the second air guide 262 and the fourth air guide 323 is connected. When the second adjustment element is in the sixth position, the air path between the second air guide 262 and the fourth air guide 323 is disconnected.

[0125] In some embodiments, the suction port module 1 is connected to the atomization module 3.

[0126] The suction port 11 can be selectively in fluid communication with one of the third air guide 313 and the fourth air guide 323 by rotatingly connecting the suction port module 1 to the atomization module 3, or by detachably connecting the suction port module 1 to the atomization module 3 in at least two azimuthal orientations.

[0127] In some embodiments, the first atomization member 312 and the second atomization member 322 are configured to be simultaneously in fluid communication with the suction port 11 and to be independently operable. Thus, the first atomizer 31 and the second atomizer 32 can be simultaneously operated, or either of the first atomizer 31 and the second atomizer 32 can be operated independently.

[0128] When the first atomization member 312 and the second atomization member 322 are simultaneously operated, the first atomizer 31 and the second atomizer 32 can almost simultaneously generate aerosols, thereby increasing the total amount of aerosols discharged from the suction port 11, or causing the aerosols discharged from the suction port 11 to be a mixed aerosol including at least the first aerosol and the second aerosol.

[0129] In some embodiments, when the first atomization member 312 and the second atomization member 322 are simultaneously operated, the aerosol-generating substrate in the first accommodation cavity 311 and the aerosol-generating substrate in the second accommodation cavity 321 can be almost simultaneously consumed; or when the first atomizer 31 and the second atomizer 32 are simultaneously operated, the second reserve chamber 22 can simultaneously supply the second accommodation cavity 321 with the aerosol-generating substrate while the first reserve chamber 21 supplies the first accommodation cavity 311 with the aerosol-generating substrate.

[0130] When the first atomization member 312 and the second atomization member 322 are both in fluid communication with the air inlet 11 and only the first atomization member 312 is working in both the first atomization member 312 and the second atomization member 322, the aerosol generating substrate in the first containing cavity 311 will be consumed, and the amount of the aerosol generating substrate in the second containing cavity 321 will basically remain stable, so that the first reserve tank 21 can automatically supply the aerosol generating substrate to the first containing cavity 311, and the second flow-through passage 232 between the second reserve tank 22 and the second containing cavity 321 can be in a conductive state, but based on the air pressure balance at this time, the second reserve tank 22 can automatically not supply the aerosol generating substrate to the second containing cavity 321.

[0131] When the first atomization member 312 and the second atomization member 322 are both in fluid communication with the air inlet 11 and only the second atomization member 322 is working in both the first atomization member 312 and the second atomization member 322, the aerosol generating substrate in the second containing cavity 321 will be consumed, and the amount of the aerosol generating substrate in the first containing cavity 311 will basically remain stable, so that the second reserve tank 22 can automatically supply the aerosol generating substrate to the second containing cavity 321, and the first flow-through passage 231 between the first reserve tank 21 and the first containing cavity 311 can be in a conductive state, but based on the air pressure balance at this time, the first reserve tank 21 can automatically not supply the aerosol generating substrate to the first containing cavity 311.

[0132] In some embodiments, when the first atomization member 312 and the second atomization member 322 are both in fluid communication with the air inlet 11, the first atomization member 312 and the second atomization member 322 are configured to alternately atomize the corresponding aerosol generating substrate. For example, in a first time period, only the first atomization member 312 works in the first atomization member 312 and the second atomization member 322, so that the aerosol generating device can generate a first aerosol; in a second time period, only the second atomization member 322 works in the first atomization member 312 and the second atomization member 322, so that the aerosol generating device can generate a second aerosol; in a third time period, only the first atomization member 312 works in the first atomization member 312 and the second atomization member 322 again, so that the aerosol generating device can generate the first aerosol again, and so on. The first atomization member 312 and the second atomization member 322 work alternately, so as to alternately generate the first aerosol and the second aerosol.

[0133] The first atomization member 312 and the second atomization member 322 can use different powers to atomize the aerosol generating substrate. The first atomization member 312 and the second atomization member 322 can use the same power to atomize the aerosol generating substrate.

[0134] In some embodiments, reference can be made to Figures 7-9The third air guide tube 313 is in fluid communication with the fourth air guide tube 323 and the air inlet 11, and is arranged downstream of the fourth air guide tube 323 in the airflow direction. Thus, the first atomizer 31 is arranged downstream of the second atomizer 32 in the airflow direction, and the aerosol generated by the second atomizer 32 needs to flow to the air inlet 11 via the third air guide tube 313.

[0135] As a typical example, reference can be made to Figure 7 and Figure 8 The first air guide tube 261 is in fluid communication with the third air guide tube 313 and the air inlet 11, and is arranged downstream of the third air guide tube 313 in the airflow direction. Thus, the aerosol generated by the first atomizer 31 and the second atomizer 32 needs to flow to the air inlet 11 via the first air guide tube 261. When the first atomizer 31 and the second atomizer 32 work simultaneously, the aerosol generated by the first atomizer 31 and the aerosol generated by the second atomizer 32 can be mixed in the first air guide tube 261. Based on this, the first reserve tank 21 can be arranged between the first atomizer 31 and the mouthpiece module 1.

[0136] As a typical example, reference can be made to Figure 7 The second air guide tube 262 is in fluid communication with the fourth air guide tube 323 and the third air guide tube 313, and is arranged between the fourth air guide tube 323 and the third air guide tube 313 in the airflow direction. Thus, the aerosol generated by the second atomizer 32 needs to flow to the first atomizer 31 via the second air guide tube 262. Based on this, the second reserve tank 22 can be arranged between the first atomizer 31 and the second atomizer 32.

[0137] In some embodiments, reference can be made to Figure 1 The aerosol generating device 100 further comprises a power supply module 120 configured to independently provide electric power to the first atomizer 31 and the second atomizer 32, so that the first atomizer 31 and the second atomizer 32 can work independently. More specifically, the first atomizer 31 and the second atomizer 32 can work independently includes that the first atomizer 31 and the second atomizer 32 can work simultaneously and with the same electric power or with different electric power, the first atomizer 31 and the second atomizer 32 can work alternatively, or the first atomizer 31 and the second atomizer 32 can not work at all.

[0138] The power supply module 120 comprises a power supply (not shown), which can be any suitable battery, such as a lithium battery, a rechargeable battery, or a disposable battery, etc.

[0139] In some embodiments, reference can be made to Figure 1The atomization module 3 is configured to be detachably connected with the power supply module 120, so that the atomization module 3 can be assembled on the power supply module 120 and can also be removed from the power supply module 120. Therefore, the atomizer or the atomization module 3 can be replaced when the service life of the atomization component in the atomizer reaches the upper limit.

[0140] More specifically, the power supply module 120 can further include a bracket 121 and a plurality of groups of power supply electrodes 122 electrically connected with the power supply. The power supply can be held in the bracket 121, and the power supply electrodes 122 are fixed on the bracket. Each atomizer includes a power taking electrode (not shown), and the power taking electrode of each atomizer abuts against a group of power supply electrodes 122. Therefore, when the atomization module 3 is assembled with the power supply module 120, each atomizer can be simply and quickly electrically connected with the corresponding power supply electrode 122, and when it is necessary to remove the atomization module 3 from the power supply module 120, the connection between the atomizer and the corresponding power supply electrode 122 can be conveniently disconnected.

[0141] For more details, please refer to Figure 1 and Figure 2 The atomization module 3 can further include a third magnetic member 34, and correspondingly, the power supply module 120 can also include a fourth magnetic member 123. The fourth magnetic member 123 can be held on the bracket 121. When the atomization module 3 is assembled with the power supply module 120, the third magnetic member 34 is magnetically attracted to the fourth magnetic member 123, so that the atomizer can stably abut against the corresponding power supply electrode 122.

[0142] The power supply module 120 can further include a housing 124. The power supply and the bracket 121 are arranged in the housing 124, and the proximal end of the housing 124 further has a docking cavity 1241. When the atomization module 3 is assembled with the power supply module 120, at least part of the atomization module 3 is located in the docking cavity 1241.

[0143] In some embodiments, at least part of the reserve module 2 is located outside the housing 124, so that at least part of the reserve module 2 is exposed. Therefore, the user can operate the part of the reserve module 2 exposed outside to remove the reserve module 2, so that the reserve module 2 can be replaced.

[0144] Further, the reserve module 2 and the atomization module 3 are configured to be separately stored, and the reserve module 2 and the atomization module 3 can be assembled to form an integral whole which is not easy to be disassembled or cannot be disassembled, so that the user can drive the reserve module 2 to remove the atomization module 3 from the docking cavity 1241 by operating the part of the reserve module 2 exposed outside. Wherein, the reserve module 2 and the atomization module 3 can be assembled to form an integral whole which is not easy to be disassembled, which means that the connection force between the reserve module 2 and the atomization module 3 is greater than the connection force between the atomization module 3 and the power module 120, for example, the connection force between the reserve module 2 and the atomization module 3 is greater than the magnetic attraction force between the third magnetic member 34 and the fourth magnetic member 123, so that when the force acts on the reserve module 2, the connection between the atomization module 3 and the power module 120 can be disconnected before and easily than the connection between the reserve module 2 and the atomization module 3, so that the reserve module 2 can drive the atomization module 3 to be removed from the docking cavity 1241.

[0145] In the embodiments as described above, Figure 3 and Figure 4 The reserve module 2 and the atomization module 3 are connected in a non-disassemblable snap connection manner. Therefore, before the reserve module 2 and the atomization module 3 are assembled, the reserve module 2 and the atomization module 3 can be separately stored, and after the reserve module 2 and the atomization module 3 are assembled, the reserve module 2 and the atomization module 3 cannot be disassembled again. Specifically, the reserve module 2 is provided with a clamping groove 29, and the atomization module 3 is provided with a clamping protrusion 35, the surface of the clamping protrusion 35 facing the second direction is a slope surface, so that the reserve module 2 can be assembled with the atomization module 3 along the first direction, and the second direction is opposite to the first direction; the surface of the clamping protrusion 35 facing the first direction is substantially perpendicular to the first direction, and after the reserve module 2 and the atomization module 3 are assembled, the surface of the clamping protrusion 35 facing the first direction interferes with the edge of the clamping groove 29 in the second direction, so that the reserve module 2 and the atomization module 3 cannot be disassembled again along the second direction.

[0146] Please refer to Figure 1 and Figure 2 The present application provides an embodiment of a reserve assembly 110, which comprises the mouthpiece module 1 according to any one of the above embodiments and the reserve module 2 according to any one of the above embodiments, and the air inlet 11 is configured to be selectively in fluid communication with one of the first air guide pipe 261 and the second air guide pipe 262.

[0147] It should be noted that the specification and drawings of the present application provide a preferred embodiment of the present application, but are not limited to the embodiments described in the specification, and further, those skilled in the art can improve or transform according to the above description, and all these improvements and transformations shall belong to the protection scope of the claims of the present application.
