[0043] The embodiment of the present application provides an aerosol generating device 1.

[0044] It should be noted that the specific type of aerosol generating device 1 provided by the embodiment of the present application is not limited. For example, the aerosol generating device 1 can be a medical atomization equipment, can also be an air humidifier, and can also be an electronic cigarette or the like.

[0045] Please refer to Figures 1 to 8 , the aerosol generating device 1 comprises an atomization assembly, at least one additional oil tank 20, a suction nozzle 30 and an air outlet channel 1a.

[0046] The atomization assembly comprises a plurality of atomization core assemblies 10, each of which has a main storage cavity 10a and an atomization cavity 10b in communication with each other, the main storage cavity 10a is used for storing an aerosol generating substrate, and each atomization core assembly 10 is arranged along a first direction, and the first direction intersects the axial direction of the aerosol generating device 1.

[0047] At least one additional oil tank 20 is located on one side of at least one atomization core assembly 10 along the axial direction, and the additional oil tank 20 has an additional storage cavity 20a, and the additional storage cavity 20a is in communication with at least one main storage cavity 10a.

[0048] The suction nozzle 30 is in communication with at least one atomization cavity 10b through the air outlet channel 1a.

[0049] The plurality refers to two, three and more. For example, the number of atomization core assemblies 10 is two.

[0050] The at least one can be one or multiple. Exemplarily, the number of the additional oil tanks 20 is multiple, and the multiple additional oil tanks 20 can be arranged at intervals along the first direction, and each of the additional oil tanks 20 is independent and does not interfere with each other, and the additional storage cavities 20a of each of the additional oil tanks 20 are not communicated with each other.

[0051] Each of the atomization core assemblies 10 has a main storage cavity 10a and an atomization cavity 10b communicated with each other, which means that for each of the atomization core assemblies 10, when not being docked with the additional oil tank 20, the main storage cavity 10a of the atomization core assembly 10 itself reserves the aerosol generating substrate, and the aerosol generating substrate in the main storage cavity 10a can enter the atomization cavity 10b and be atomized in the atomization cavity 10b to generate aerosol. The arrangement of the main storage cavity 10a can reduce the probability of dry burning, and when being communicated with the additional storage cavity 20a, the aerosol generating substrate in the additional storage cavity 20a can be guided to the corresponding atomization cavity 10b for atomization, so as to improve the aerosol generated by a single atomization core assembly 10.

[0052] Each of the atomization core assemblies 10 is arranged at intervals along the first direction, which means that each of the atomization core assemblies 10 can work independently and does not interfere with each other, and each of the main storage cavities 10a of each of the atomization core assemblies 10 is not communicated with each other, and there is no shared part or intersection part.

[0053] The first direction intersects with the axial direction of the aerosol generating device 1, and the included angle between the first direction and the axial direction of the aerosol generating device 1 can be an acute angle, an obtuse angle or a right angle. Exemplarily, the first direction is perpendicular to the axial direction of the aerosol generating device 1.

[0054] The at least one additional oil tank 20 is located on one side of the at least one atomization core assembly 10 along the axial direction, that is, the additional oil tank 20 can be docked with the atomization core assembly 10 along the axial direction.

[0055] The additional oil tank 20 can be located at one end of the atomization core assembly 10 close to the mouthpiece 30 along the axial direction, and at this time, the mouthpiece 30, the additional oil tank 20 and the atomization core assembly 10 are sequentially docked along the axial direction. The additional oil tank 20 can also be located at one end of the atomization core assembly 10 away from the mouthpiece 30 along the axial direction, and at this time, the mouthpiece 30, the atomization core assembly 10 and the additional oil tank 20 are sequentially docked along the axial direction.

[0056] The docking mode between the mouthpiece 30, the additional oil tank 20 and the atomization core assembly 10 can be detachable docking or non-detachable docking, which is not limited herein.

[0057] The additional storage cavity 20a communicates with at least one of the main storage cavities 10a, that is, only one of the plurality of atomization core assemblies 10 can be provided with the additional oil tank 20, and the additional oil tank 20 communicates with one of the main storage cavities 10a to supplement the aerosol generating substrate to the corresponding atomization cavity 10b. The other atomization core assemblies 10 are not provided with the additional oil tank 20, and only rely on the main storage cavity 10a of the atomization core assembly 10 to supply the aerosol generating substrate to the atomization cavity 10b. Alternatively, the additional storage cavity 20a communicates with a plurality of main storage cavities 10a. The plurality of main storage cavities 10a can be the main storage cavities 10a of all atomization core assemblies 10, or can be part of the main storage cavities 10a of all atomization core assemblies 10. In this way, a single additional storage cavity 20a can provide aerosol generating substrate for a plurality of main storage cavities 10a.

[0058] Exemplarily, the number of additional storage cavities 20a defined by a single additional oil tank 20 is one. The single additional storage cavity 20a communicates with one main storage cavity 10a.

[0059] The air outlet channel 1a is a set of channels that can supply the airflow to the air inlet 30 downstream of each atomization cavity 10b along the airflow direction.

[0060] It can be understood that, in the embodiment in which the air inlet 30, the additional oil tank 20, and the atomization core assembly 10 are sequentially connected in the axial direction, the air outlet channel 1a can include the airflow channel in the additional oil tank 20 and the set of airflow channels between the air inlet 30 and the additional oil tank 20. In the embodiment in which the air inlet 30, the atomization core assembly 10, and the additional oil tank 20 are sequentially connected in the axial direction, the air outlet channel 1a can be the set of airflow channels between the air inlet 30 and the atomization core assembly 10.

[0061] It should be noted that the air inlet 30 communicates with at least one atomization cavity 10b through the air outlet channel 1a, that is, the air inlet 30 can communicate with any one or more atomization cavities 10b through the air outlet channel 1a. When the air inlet 30 communicates with one of the atomization cavities 10b through the air outlet channel 1a, the negative pressure of the air inlet 30 can act on the atomization cavity 10b. The negative pressure of the air inlet 30 can act on the atomization cavity 10b through the air outlet channel 1a. Aerosol is generated in the atomization cavity 10b, and the aerosol flows to the air inlet 30 through the air outlet channel 1a under the action of the negative pressure of the air inlet 30, so that the user can inhale. At this time, the remaining atomization cavities 10b are not connected to the air inlet 30, and the negative pressure of the air inlet 30 cannot act on the remaining atomization cavities 10b through the air outlet channel 1a. When the air inlet 30 communicates with all atomization cavities 10b through the air outlet channel 1a, the negative pressure of the air inlet 30 can act on all atomization cavities 10b. The aerosol generated by each atomization cavity 10b flows to the air inlet 30 through the air outlet channel 1a.

[0062] It can be understood that the communication with one atomization cavity 10b, the non-communication with the rest of the atomization cavities 10b, or the communication with all the atomization cavities 10b can be realized by the movement of the suction nozzle 30 itself, or the movement of the rest of the structure can realize the communication of the suction nozzle 30 with one atomization cavity 10b, the non-communication with the rest of the atomization cavities 10b, and the communication with all the atomization cavities 10b, and at this time, the rest of the structure can define at least part of the air outlet channel 1a.

[0063] That is, the suction nozzle 30 can selectively communicate with at least any one of the plurality of atomization cavities 10b. In this way, the user can change different suction modes, for example, the user can realize larger mouth suction and / or different taste suction of a single aerosol generating device 1 by making the suction nozzle 30 communicate with different one of the atomization cavities 10b respectively, or the user can realize larger content of aerosol suction at one time and / or simultaneous suction of different taste mixed aerosol at one time, and realize the diversification of suction by making the suction nozzle 30 communicate with multiple atomization cavities 10b at the same time.

[0064] Exemplarily, in some embodiments, one end of the air outlet channel 1a can have multiple interfaces to respectively interface with each atomization cavity 10b, and the other end of the air outlet channel 1a can have only one interface which communicates with the suction nozzle 30, in which case the negative pressure of the suction nozzle 30 can act on each atomization cavity 10b through the interface of the other end of the air outlet channel 1a, and each atomization cavity 10b can simultaneously perform atomization work, in which case the suction nozzle 30 communicates with all the atomization cavities 10b through the air outlet channel 1a.

[0065] In other embodiments, referring to Figure 2 and Figure 7 , one end of the air outlet channel 1a can have multiple interfaces to respectively interface with each atomization cavity 10b, and the other end of the air outlet channel 1a can also have multiple interfaces, at least any one of the multiple interfaces communicates with the suction nozzle 30, in which case the negative pressure of the suction nozzle 30 can be transmitted to at least any one of the atomization cavities 10b, and at least any one of the atomization cavities 10b performs atomization work, in which case one end of the air outlet channel 1a can communicate with any one or more of the atomization cavities 10b to realize the air outlet of a single atomization cavity 10b or the simultaneous air outlet of multiple atomization cavities 10b.

[0066] In still other embodiments, one end of the air outlet channel 1a can have multiple interfaces which are separably interfaced with each atomization cavity 10b, and the other end of the air outlet channel 1a can also have multiple interfaces which are separably interfaced with the suction nozzle 30. In this way, the communication of the suction nozzle 30 with one atomization cavity 10b or the simultaneous communication with multiple atomization cavities 10b can be realized by the communication of the interfaces at both ends of the air outlet channel 1a with the atomization cavities 10b and the suction nozzle 30 respectively.

[0067] Note that the aerosol generating substrate includes, but is not limited to, a material for medical, health, beauty, and health care purposes.

[0068] It can be understood that the amount of aerosol generating substrate stored in each main storage cavity 10a can be consistent or inconsistent. For example, the amount of aerosol generating substrate stored in each main storage cavity 10a is consistent.

[0069] The aerosol generating device 1 provided by the embodiments of the present application has at least one additional oil tank 20 and a plurality of atomization core assemblies 10, which can make the aerosol generating device 1 have enough aerosol generating substrate, generate enough aerosol, reduce the risk of dry burning during atomization, and have high atomization uniformity. In addition, the nozzle 30 communicates with at least one atomization cavity 10b through the air outlet channel 1a, which can meet the different needs of users for the amount of aerosol and the taste of suction, and improve the user experience.

[0070] In some embodiments, referring to Figures 2 to 8 , the number of additional oil tanks 20 is multiple, and the multiple additional oil tanks 20 correspond to the multiple main storage cavities 10a one by one. The main storage cavity 10a is used to guide the aerosol generating substrate in the additional storage cavity 20a to the atomization cavity 10b, and the multiple additional storage cavities 20a are arranged along the first direction.

[0071] That is, the number of additional oil tanks 20 is consistent with the number of atomization core assemblies 10, each atomization core assembly 10 corresponds to one additional oil tank 20, and one additional oil tank 20 is arranged corresponding to one main storage cavity 10a and one atomization cavity 10b. In this way, a single additional oil tank 20 only needs to be connected to one atomization core assembly 10, which is convenient to connect and will not interfere with other atomization core assemblies 10 and additional oil tanks 20. The replenishment of aerosol generating substrate can also be more smooth. If the additional oil tank 20 and the atomization core assembly 10 are detachably connected, and the atomization core assembly 10 and the additional oil tank 20 are arranged one by one, the convenience of disassembly and assembly can also be increased.

[0072] In this embodiment, the multiple additional oil tanks 20 correspond to the multiple main storage cavities 10a one by one, which is convenient to connect, and at the same time, can supplement more aerosol generating substrate for the corresponding main storage cavity 10a, so that a single atomization core assembly 10 can generate more aerosol, and increase the aerosol that a single aerosol generating device 1 can generate. At the same time, the arrangement of multiple additional oil tanks 20 can also increase the simplicity of connecting the additional oil tank 20 and the atomization core assembly 10, and facilitate the formation of a symmetrical arrangement structure.

[0073] For example, in some embodiments, referring to Figures 2 to 5 , Figures 7 to 8, the number of the atomizing core assemblies 10 is two, the number of the additional oil tanks 20 is two, the two additional oil tanks 20 are symmetrically arranged, and the two atomizing core assemblies 10 are symmetrically arranged at the center, so that the shape and size of each additional oil tank 20 are the same, the shape and size of each atomizing core assembly 10 are the same, the atomizing core assemblies 10 can be interchangeably installed at the intended positions without distinguishing, and the assembly efficiency is improved. The intended position refers to the designed installation position of the atomizing core assembly 10.

[0074] In some embodiments, referring to Figure 3 The aerosol generating device 1 is provided with an air inlet channel 1c, at least any one of the atomizing cavities 10b is in communication with the external environment through the air inlet channel 1c, and the aerosol generating device 1 comprises at least one sensor for detecting the airflow in the air inlet channel 1c.

[0075] Here, the air inlet channel 1c is a space for the airflow in the external environment to flow, which is located upstream of each atomizing cavity 10b along the airflow direction.

[0076] It can be understood that at least any one of the atomizing cavities 10b is in communication with the external environment through the air inlet channel 1c, which means that any one of the atomizing cavities 10b can be in air communication with the air inlet channel 1c, and the remaining atomizing cavities 10b can be in abutment with the air inlet channel 1c, but the air in the external environment cannot enter the remaining atomizing cavities 10b, at this time, only one atomizing cavity 10b performs atomization work; or part (more than one) or all of the atomizing cavities 10b can be in communication with the air inlet channel 1c, at this time, part (more than one) or all of the atomizing cavities 10b perform atomization work.

[0077] Exemplarily, taking the number of the atomizing cavities 10b as two as an example, the air inlet channel 1c can comprise a main air inlet channel, a first starting air passage and a second starting air passage, the first starting air passage and the second starting air passage are not in communication with each other, one end of the first starting air passage is in communication with the main air inlet channel, and the other end is in communication with one atomizing cavity 10b, one end of the second starting air passage is in communication with the main air inlet channel, and the other end is in communication with the other atomizing cavity 10b, and the main air inlet channel is in communication with the external environment. When the air outlet channel 1a is in air communication with one of the atomizing cavities 10b, under the negative pressure of the suction nozzle 30, the airflow in the external environment flows to one of the first starting air passage or the second starting air passage through the main air inlet channel, and the other one of the first starting air passage or the second starting air passage does not intake air, at this time, only one atomizing core assembly 10 performs atomization work. When the air outlet channel 1a is in air communication with both of the atomizing cavities 10b, under the negative pressure of the suction nozzle 30, the airflow in the external environment flows to the first starting air passage or the second starting air passage through the main air inlet channel, respectively, to flow to the two atomizing cavities 10b, at this time, both of the atomizing core assemblies 10 perform atomization work.

[0078] The sensor can detect the airflow flow in the air inlet channel 1c, and exemplarily detect a negative pressure signal, so that the aerosol generating device 1 can start the corresponding atomization core assembly 10 according to the negative pressure signal, and close the atomization core assembly 10 without the negative pressure signal. Exemplarily, when only one atomization cavity 10b is in air outlet communication with the air outlet channel 1a, at this time, the negative pressure of the suction nozzle 30 acts on the atomization cavity 10b, the sensor can detect the negative pressure signal transmitted by the atomization cavity 10b, so that the atomization core assembly 10 can be powered on to realize atomization, while the remaining atomization cavities 10b are not in air outlet communication with the air outlet channel 1a, and the negative pressure of the suction nozzle 30 cannot act on the remaining atomization cavities 10b, so that the sensor cannot detect the negative pressure signal, and the atomization core assembly 10 corresponding to the remaining atomization cavities 10b cannot be powered on and cannot atomize. In this way, in this embodiment, the sensor is provided to increase the atomization reliability and reduce the probability of mis-starting, and at the same time, the atomization starting is more convenient without the need for pressing a key or the like.

[0079] In some embodiments, the suction nozzle 30, the additional oil tank 20 and the atomization core assembly 10 are sequentially butted in the axial direction. In this way, on the one hand, the resistance of the aerosol generating substrate in the additional oil tank 20 to flow to the main storage cavity 10a can be reduced to increase the flow smoothness, and on the other hand, at least a part of the air outlet channel 1a can be defined by the additional oil tank 20, so that there is a sufficient air outlet path to make the temperature of the aerosol flowing to the suction nozzle 30 appropriate.

[0080] In some embodiments, referring to Figure 2 and Figure 7 , the air outlet channel 1a includes a plurality of sub-air passages 1b which are not in communication with each other, one end of each sub-air passage 1b corresponds to one of the plurality of atomization cavities 10b, and the other end of at least one sub-air passage 1b is in communication with the suction nozzle 30.

[0081] That is, the number of sub-air passages 1b corresponds to the number of atomization cavities 10b.

[0082] The other end of at least one sub-air passage 1b is in communication with the suction nozzle 30. Here, it can be that only the other end of one sub-air passage 1b is in communication with the suction nozzle 30, at this time, the negative pressure of the suction nozzle 30 can act on the corresponding atomization cavity 10b through the sub-air passage 1b, the atomization cavity 10b can intake air to perform atomization, and the remaining sub-air passages 1b are not in communication with the suction nozzle 30, so the negative pressure of the suction nozzle 30 cannot act on the corresponding atomization cavity 10b through the remaining sub-air passages 1b, and the remaining atomization cavities 10b do not intake air and do not perform atomization. Of course, it can also be that the other end of all sub-air passages 1b is in communication with the suction nozzle 30, at this time, the negative pressure of the suction nozzle 30 can act on the corresponding atomization cavity 10b through all sub-air passages 1b, and all atomization cavities 10b can intake air to perform atomization.

[0083] Of course, it can also be that part (more than one) of all sub-air channels 1b are in communication with the suction nozzle 30, and another part is not in communication with the suction nozzle 30. Details can be referred to the above, and will not be repeated here.

[0084] It can be understood that the manner of realizing that the suction nozzle 30 is not in communication with the atomization cavity 10b is not limited, for example, the suction nozzle 30 can be staggered with the sub-air channel 1b to realize the non-communication, or the intermediate structure can be used for stopping.

[0085] The arrangement of the sub-air channel 1b is not limited. Exemplarily, taking the number of sub-air channels 1b as two as an example, please refer to Figure 2 and Figure 7 , the two sub-air channels 1b are arranged at intervals along the first direction, one end of the two sub-air channels 1b is directly in communication with one atomization cavity 10b respectively, and at least any one of the two sub-air channels 1b is directly in communication with the suction nozzle 30. In this case, one end (the end opposite to the atomization cavity 10b) of the air outlet channel 1a has two interfaces, and the other end (the end opposite to the suction nozzle 30) has two interfaces, and the two sub-air channels 1b are arranged in parallel.

[0086] In other embodiments, one end of the two sub-air channels 1b is directly in communication with one atomization cavity 10b respectively, and the other end of the two sub-air channels 1b is indirectly in communication with the suction nozzle 30, that is, the air outlet channel 1a is also provided with a mixed air channel, the other end of the two sub-air channels 1b is in communication with the mixed air channel, and the end of the mixed air channel away from the two sub-air channels 1b is in communication with the suction nozzle 30. In this embodiment, one end (the end opposite to the atomization cavity 10b) of the air outlet channel 1a has two interfaces, and the other end (the end opposite to the suction nozzle 30) has only one interface.

[0087] In this embodiment, the sub-air channel 1b can be arranged one by one with each atomization cavity 10b, and the air outlet is smooth and reliable. At the same time, the suction nozzle 30 can selectively communicate with at least any one of the sub-air channels 1b, which is convenient to meet the different needs of users for the amount of aerosol suction and the taste of suction, and improves the user experience.

[0088] The formation of the air outlet channel 1a is not limited. Exemplarily, in the embodiment in which the suction nozzle 30, the additional oil tank 20, and the atomization core assembly 10 are sequentially butted along the axial direction, the additional oil tank 20 has a space that is not in communication with the additional storage cavity 20a, and the space defines at least one sub-air channel 1b. When the additional oil tank 20 corresponds to the atomization cavity 10b one by one, a single additional oil tank 20 defines one sub-air channel 1b.

[0089] Exemplarily, please refer to Figure 4 , Figure 5 and Figure 8The additional oil tank 20 corresponds to the atomization cavity 10b one-to-one, and a space between the inner wall and the outer wall of the additional oil tank 20 defines an additional storage cavity 20a, and the inner wall of the additional oil tank 20 defines at least part of the sub-air channel 1b. In this way, the liquid storage sealing property and reliability can be improved, the airflow passage can be reduced, and the axial size of the aerosol generating device 1 can be reduced.

[0090] For example, the sub-air channel 1b can be coaxially arranged with the atomization cavity 10b in communication with the atomization cavity 10b. In this way, the aerosol can flow smoothly from the atomization cavity 10b to the corresponding sub-air channel 1b, the turning probability can be reduced, and the atomization efficiency can be improved.

[0091] The manner in which the suction nozzle 30 selectively communicates with any one of the sub-air channels 1b is not limited.

[0092] In some embodiments, referring to Figures 1 to 5 The suction nozzle 30 can move relative to the additional oil tank 20 to communicate with at least one of the sub-air channels 1b.

[0093] It should be noted that the movement of the suction nozzle 30 can be rotation, sliding, or a combination of multiple movement forms, which is not limited herein.

[0094] For example, the suction nozzle 30 is rotationally connected to at least one of the additional oil tanks 20. Here, when the number of additional oil tanks 20 is one, the suction nozzle 30 is rotationally connected to the one additional oil tank 20, and when the number of additional oil tanks 20 is multiple, the suction nozzle 30 is rotationally connected to all of the additional oil tanks 20. In this way, the suction nozzle 30 can rotate relative to at least one of the additional oil tanks 20 to rotate the suction nozzle 30 relative to the sub-air channels 1b, thereby changing the communication mode of the suction nozzle 30 with the sub-air channels 1b and realizing the communication of the suction nozzle 30 with at least one of the sub-air channels 1b.

[0095] That is, in this embodiment, the communication mode with the sub-air channels 1b is adjusted by the movement of the suction nozzle 30 itself without the need for additional intermediate structures. After the atomization of all the aerosol generating substrates corresponding to one of the atomization cavities 10b is completed, the atomization of the next atomization cavity 10b can be realized by moving the suction nozzle 30, multiple large-volume puffs can be realized, or when the suction flavor needs to be changed or the aerosol suction amount needs to be increased, the movement of the suction nozzle 30 can also be realized to meet various suction requirements and improve the user experience. At the same time, the overall structure of the aerosol generating device 1 can also be relatively simple.

[0096] In other embodiments, referring to Figures 5 to 8The aerosol-generating device 1 comprises a switch member 50 arranged between the mouthpiece 30 and the atomization core assembly 10, the switch member 50 has a communication hole 50a defining at least part of the air outlet channel 1a, and the switch member 50 is movable relative to the mouthpiece 30 and the atomization core assembly 10 to enable the mouthpiece 30 to communicate with at least one of the atomization cavities 10b through the communication hole 50a.

[0097] It should be noted that the movement of the switch member 50 can be rotation, sliding or a combination of multiple movement forms, which is not limited here.

[0098] It should be noted that the number of switch members 50 is not limited, and there can be only one switch member 50, which enables the mouthpiece 30 to communicate with at least one atomization cavity 10b, or there can be multiple switch members 50, which is not limited here.

[0099] It can be understood that the switch member 50 is arranged between the mouthpiece 30 and the atomization core assembly 10. In the embodiment in which the mouthpiece 30, the additional oil tank 20, and the atomization core assembly 10 are sequentially butted in the axial direction, the switch member 50 is arranged at the butt joint of the mouthpiece 30 and the additional oil tank 20, and at this time, the communication hole 50a and the additional oil tank 20 jointly define the air outlet channel 1a. In the embodiment in which the mouthpiece 30, the atomization core assembly 10, and the additional oil tank 20 are sequentially butted in the axial direction, the switch member 50 is arranged at the butt joint of the mouthpiece 30 and the atomization core assembly 10, and the additional oil tank 20 does not participate in the structural composition of the air outlet channel 1a. The communication hole 50a defines the air outlet channel 1a, and when the switch member 50 corresponds to each atomization cavity 10b, the communication hole 50a of one switch member 50 defines one sub-air passage 1b.

[0100] In this way, the communication of the mouthpiece 30 with at least one of the atomization cavities 10b through the communication hole 50a includes multiple cases.

[0101] The first case is that the additional oil tank 20 is arranged between the mouthpiece 30 and the atomization core assembly 10, the additional oil tank 20 defines at least part of the sub-air passage 1b, there is only one switch member 50, the switch member 50 has only one communication hole 50a, and when the switch member 50 moves relative to the mouthpiece 30 and the atomization core assembly 10, the sub-air passage 1b communicated with the communication hole 50a is adjusted to enable the mouthpiece 30 to communicate with different sub-air passages 1b respectively. In this case, the mouthpiece 30 communicates with one sub-air passage 1b at a time, the communication hole 50a is not part of the sub-air passage 1b, and the communication hole 50a is a common communication passage. Through the movement of the single communication hole 50a, the communication with different sub-air passages 1b is realized, and then the communication with different atomization cavities 10b is realized.

[0102] The second kind: the number of switch pieces 50 is only one, and the single switch piece 50 is provided with multiple communication holes 50a, the number of communication holes 50a corresponds to the number of atomization cavities 10b, at this time, the communication hole 50a defines at least part of the sub-air channel 1b. In this case, the setting position of the additional oil storehouse 20 is not limited. Through the movement of the switch piece 50, the communication or misalignment between the multiple communication holes 50a and the corresponding atomization cavities 10b is realized, so that the single suction nozzle 30 is communicated with one or more atomization cavities 10b.

[0103] The third kind: the number of switch pieces 50 is multiple, and the single switch piece 50 is provided with one communication hole 50a, the number of communication holes 50a corresponds to the number of atomization cavities 10b. At this time, the communication hole 50a defines at least part of the sub-air channel 1b. In this case, the setting position of the additional oil storehouse 20 is not limited. Through the movement of the multiple switch pieces 50, the communication or misalignment between the multiple communication holes 50a and the corresponding atomization cavities 10b is realized, so that the single suction nozzle 30 is communicated with one or more atomization cavities 10b.

[0104] It should be noted that in this embodiment, there is no relative movement between the suction nozzle 30, the atomization core assembly 10 and the additional oil storehouse 20.

[0105] In this embodiment, the switch piece 50 is provided, and only by the movement of the switch piece 50, the suction nozzle 30 is communicated with at least one atomization cavity 10b through the communication hole 50a, which can reduce the structural limitation of the suction nozzle 30, at the same time, the communication reliability and disconnection reliability of the switch piece 50 are high, and the state switching of the aerosol generating device 1 is more reliable.

[0106] The specific structure of the switch piece 50 is not limited, which can be a knob structure or other types of structures, which is not limited here.

[0107] Exemplarily, please refer to Figure 7 and Figure 8 , the suction nozzle 30 is provided with at least one through slot 30a in the axial direction, the switch piece 50 includes a main body part 501 and a driving part 502 connected with each other, the driving part 502 is arranged in the through slot 30a and exposed on the outer surface of the aerosol generating device 1, the main body part 501 is provided with a communication hole 50a, and the driving part 502 can drive the main body part 501 to rotate relative to the suction nozzle 30 under the action of an external force, so that the communication hole 50a is communicated with at least one of the suction nozzle 30 and each atomization cavity 10b, or the communication hole 50a is misaligned with the suction nozzle 30.

[0108] The driving part 502 is arranged in the through groove 30a and exposed on the outer surface of the aerosol generating device 1, the through groove 30a provides a mounting space and a movement space for the driving part 502, the driving part 502 can be seen by the user, and the user can make the main body part 501 rotate relative to the suction nozzle 30 by applying an external force to the exposed driving part 502, so that the communication hole 50a moves relative to the suction nozzle 30. When the communication hole 50a communicates the suction nozzle 30 with at least one of the atomization cavities 10b, the aerosol generated by at least one of the atomization cavities 10b can flow to the suction nozzle 30 through the communication hole 50a to be inhaled by the user, and when the communication hole 50a is misaligned with the suction nozzle 30, the communication hole 50a disconnects each atomization cavity 10b from the suction nozzle 30, and none of the atomization cavities 10b generates aerosol, that is, the aerosol generating device 1 is in a closed state.

[0109] In this embodiment, the cooperation of the driving part 502 and the main body part 501 can increase the state switching reliability of the aerosol generating device 1, and the switching is convenient and does not need to be operated greatly, and the operation convenience is high.

[0110] In some embodiments, referring to Figure 7 and Figure 8 , the number of switch parts 50 is multiple, and the number of switch parts 50 corresponds to the number of atomization cavities 10b one by one. In this way, one switch part 50 corresponds to opening or closing the communication of one atomization cavity 10b with the suction nozzle 30, which is convenient for the user to know without needing to judge which atomization cavity 10b is, and one-to-one setting makes the switching more reliable and reduces the switching complexity.

[0111] In some embodiments, referring to Figure 2 and Figure 7 , the additional oil tank 20 includes at least one liquid guiding structure 203, the liquid guiding structure 203 is arranged on the side of the additional oil tank 20 close to the atomization core assembly 10, the liquid guiding structure 203 protrudes from the inner wall of the additional oil tank 20, the inner wall of the additional oil tank 20 is provided with at least one notch 20b, the notch 20b communicates with the air outlet channel 1a, the aerosol generating device 1 includes at least one liquid suction part 60, the at least one liquid suction part 60 is exposed to the air outlet channel 1a through the notch 20b and closes the notch 20b, and at least part of the liquid guiding structure 203 contacts the liquid suction part 60 to guide the condensate in the air outlet channel 1a to the liquid suction part 60.

[0112] It should be noted that part of the condensate is inevitably generated in the flow process of the aerosol, and in addition, the aerosol remaining in the air outlet channel will also generate condensate when the user stops using it. The backflow of the condensate to the atomization cavity easily makes the taste of the aerosol fade, affecting the user experience.

[0113] Therefore, in the embodiment, by arranging the liquid guide structure 203, the liquid guide structure 203 can guide the condensed liquid flowing back from the air outlet channel 1a to the atomization cavity 10b to the liquid suction member 60, and the liquid suction member 60 can adsorb the condensed liquid, so that the condensed liquid is not easy to flow back to the atomization cavity 10b, and the user experience is improved.

[0114] It can be understood that the number of the liquid guide structure 203 corresponding to one atomization cavity 10b can be one or multiple. For example, the number of the liquid guide structure 203 corresponding to one atomization cavity 10b is multiple, and the multiple liquid guide structures 203 are symmetrically arranged about the axis of the sub-air passage 1b corresponding to the atomization cavity 10b.

[0115] The specific structure of the liquid guide structure 203 is not limited. For example, the extension direction of the liquid guide structure 203 can be the same as the extension direction of the sub-air passage 1b.

[0116] It should be noted that the gap 20b is in communication with the air outlet channel 1a, and the gap 20b and the additional storage cavity 20a are not in communication with each other. The gap 20b is used for the liquid suction member 60 to be in abutment with the air outlet channel 1a.

[0117] The liquid suction member 60 is exposed to the air outlet channel 1a through the gap 20b and closes the gap 20b, which means that the liquid suction member 60 can be exposed to the air outlet channel 1a under the action of the gap 20b, so that the condensed liquid guided by the liquid guide structure 203 can directly flow to the liquid suction member 60, reducing the probability of backflow, and the liquid suction member 60 closes the gap 20b, that is, while adsorbing the condensed liquid, the probability of air leakage of the air outlet channel 1a is reduced.

[0118] It can be understood that the number of the liquid suction member 60 corresponding to one atomization cavity 10b can be one or multiple. For example, the number of the liquid suction member 60 corresponding to one atomization cavity 10b is multiple, so as to increase the reliability of liquid suction. For example, please refer to Figure 2 and Figure 7 The number of the liquid suction member 60 corresponding to one atomization cavity 10b is two, one of which adsorbs the condensed liquid adsorbed by the liquid guide structure 203, and the other of which adsorbs the condensed liquid adsorbed by the previous liquid suction member 60, so as to adsorb enough condensed liquid.

[0119] The specific structure of the liquid suction member 60 is not limited. For example, the liquid suction member 60 can be liquid suction cotton.

[0120] The specific structure of the additional oil store 20 is not limited.

[0121] In some embodiments, please refer to Figure 3 and Figure 5The additional oil tank 20 comprises a shell portion 201 and a sealing movable member 202, the shell portion 201 defines an additional storage cavity 20a, and the sealing movable member 202 is arranged on the side of the shell portion 201 facing the atomizing core assembly 10, and the atomizing core assembly 10 comprises a lead-through member 103.

[0122] When the additional oil tank 20 is separated from the atomizing core assembly 10, the sealing movable member 202 breaks the fluid path between the additional storage cavity 20a and the main storage cavity 10a.

[0123] When the additional oil tank 20 is connected with the atomizing core assembly 10, the lead-through member 103 drives the sealing movable member 202 to move relative to the shell portion 201 to make the additional storage cavity 20a and the main storage cavity 10a in fluid communication.

[0124] Exemplarily, the inner wall and the outer wall of the shell portion 201 define an aerosol generating substrate, and the inner wall of the shell portion 201 defines at least part of the sub-air channel 1b.

[0125] In this embodiment, when the additional oil tank 20 is not connected with the atomizing core assembly 10, the aerosol generating substrate in the additional oil tank 20 is sealed by the sealing movable member 202, which is isolated from air and the atomizing core assembly 10, thereby reducing the risk of leakage and facilitating transportation and storage in non-use condition. When the additional oil tank 20 is connected with the atomizing core assembly 10, the force generated by the connection drives the lead-through member 103 to drive the sealing movable member 202 to move relative to the shell portion 201, thereby opening the shell portion 201 and enabling the aerosol generating substrate to flow from the shell portion 201 to the atomizing core assembly 10, thereby increasing the reliability of atomization.

[0126] In some embodiments, referring to Figure 5 One end of the sealing movable member 202 is a fixed end 202a, and the other end is a free end 202b, the fixed end 202a is connected with the shell portion 201 and there is no relative movement between them, and the lead-through member 103 is used to drive the free end 202b to rotate relative to the connection between the free end 202b and the fixed end 202a.

[0127] The number of sealing movable members 202 is two, and the rotation directions of the free ends 202b of the two sealing movable members 202 are opposite.

[0128] The fixed end 202a is connected with the shell portion 201 and there is no relative movement between them, which means that the fixed end 202a and the shell portion 201 are in a relatively static state, and the sealing movable member 202 rotates relative to the shell portion 201 through the free end 202b.

[0129] That is, a single additional oil tank 20 comprises two sealing movable members 202, and here, the two sealing movable members 202 can be separately arranged or integrally formed.

[0130] Exemplarily, the free ends 202b of the two sealing movable members 202 are centrally symmetrically arranged about the axis of the shell 201, and the axis of the shell 201 can be parallel to the axial direction of the aerosol generating device 1.

[0131] In this embodiment, the arrangement of the two sealing movable members 202 can increase the liquid flow rate of the shell 201 and improve the atomization uniformity. The rotating directions of the free ends 202b of the two sealing movable members 202 are opposite, which can further increase the flow smoothness of the aerosol generating substrate of the shell 201 towards the atomization core assembly 10.

[0132] The specific structure of the atomization core assembly 10 is not limited.

[0133] In some embodiments, referring to Figure 2 and Figure 7 , the atomization core assembly 10 includes an atomization core 101 and a liquid storage member 102. The atomization core 101 is arranged in the atomization cavity 10b, and the liquid storage member 102 is located in the main storage cavity 10a. The liquid storage member 102 stores the aerosol generating substrate, and the liquid storage volume of the liquid storage member 102 is smaller than the liquid storage volume of the additional oil reservoir 20.

[0134] It can be understood that the liquid storage member 102 can be a structure such as liquid storage cotton.

[0135] The atomization core 101 can be a structure such as a heating wire or a heating mesh.

[0136] In this embodiment, the liquid storage member 102 can provide the aerosol generating substrate for the atomization cavity 10b, reduce the probability of dry burning of the atomization core 101, and the liquid storage volume of the liquid storage member 102 is smaller than the liquid storage volume of the additional oil reservoir 20, i.e., the amount of the aerosol generating substrate stored by the liquid storage member 102 is smaller than the amount of the aerosol generating substrate stored by the additional oil reservoir 20. In this way, the structural complexity of the atomization core assembly 10 can be reduced, and the atomization reliability can be improved. A single atomization core assembly 10 can atomize sufficient aerosol generating substrate to meet the user's smoking demand.

[0137] In some embodiments, referring to Figures 2 to 4 , Figures 7 to 8 The aerosol generating device 1 includes a power supply assembly 40, and the atomization core assembly 10 includes a conductive member 104. The atomization core assembly 10 or the power supply assembly 40 forms a mounting area 10c that is not in communication with the atomization cavity 10b. The power supply assembly 40 includes a power supply member 401, the power supply member 401 is arranged in the mounting area 10c, one end of the conductive member 104 is electrically connected to the atomization core 101, and at least part of the other end of the conductive member 104 is arranged in the mounting area 10c and is in separable electrical contact with the power supply member 401.

[0138] It can be understood that the specific structure of the mounting area 10c is not limited, which can be a hole or other mounting structure, which is not limited herein. Exemplarily, the mounting area 10c is arranged on the atomization core assembly 10.

[0139] The mounting area 10c is not in communication with the atomization cavity 10b, which means that the mounting area 10c and the atomization cavity 10b have no intersection or shared part. The electrically conductive part 104 and the power supply part 401 are electrically connected outside the atomization cavity 10b, which increases the electrical connection reliability.

[0140] The electrically conductive part 104 and the power supply part 401 are in separable electrical contact, that is, the electrically conductive part 104 and the power supply part 401 can be separated or abutted, which reduces the inconvenience of using welding and is convenient to disassemble and assemble.

[0141] In this embodiment, the electrically conductive part 104 is bent and deformed to realize contact with the power supply part 401. On the one hand, the contact is tight, and on the other hand, it is also convenient to realize detachable electrical connection.

[0142] The number of the electrically conductive part 104 of the single atomization core assembly 10 and the corresponding power supply part 401 is not limited, and exemplarily, the number of the electrically conductive part 104 of the single atomization core 101 and the corresponding power supply part 401 is three respectively.

[0143] Exemplarily, in the embodiment in which the number of the atomization core assembly 10 is two, the two groups of power supply parts 401 corresponding to the two atomization core assemblies 10 are arranged symmetrically about the axis center of the power supply assembly 40. In this way, the atomization core assemblies 10 can be distinguished, which is convenient to increase the smoothness of the connection between the atomization core assemblies 10 and the power supply assembly 40.

[0144] The electrically conductive part 104 can be a pin structure, and the power supply part 401 can be an electrode column structure, which is not limited herein.
