[0039] The embodiments of the application provide an aerosol generating device, referring to Figures 1 to 6 The aerosol generating device includes an atomization assembly 10 and an additional oil tank 20.

[0040] The atomization assembly 10 has an airflow passage 10a, the atomization assembly 10 comprises a mounting assembly 11 and a plurality of atomization cores 12, the mounting assembly 11 is provided with a mounting space 11a, each atomization core 12 is arranged in the mounting space 11a and surrounded by the inner wall of the mounting space 11a to form a plurality of main storage cavities 10b isolated from each other, the inner wall of the main storage cavity 10b along the first direction is provided with a liquid inlet 10c, the atomization core 12 forms at least part of the inner wall of the airflow passage 10a, the airflow passage 10a is isolated from the main storage cavity 10b, and the plurality of atomization cores 12 are arranged along the first direction and the airflow passages 10a of each atomization core 12 are in series communication with each other.

[0041] The additional oil tank 20 comprises an additional storage cavity 20a, and the liquid inlet 10c is in communication with the additional storage cavity 20a.

[0042] The atomization core 12 can absorb the aerosol generating substrate in the main storage cavity 10b surrounded by the atomization core 12, and the aerosol generating substrate absorbed in the atomization core 12 can be atomized by heating or the like.

[0043] The aerosol generating substrate is a fluid medium.

[0044] The aerosol can diffuse into the airflow passage 10a.

[0045] Both ends of the airflow passage 10a can directly or indirectly communicate with the outside of the aerosol generating device. The air outside the aerosol generating device enters the airflow passage 10a from one end of the airflow passage 10a, mixes with the atomized aerosol generating substrate to form an aerosol, and then the aerosol flows out of the airflow passage 10a from the other end of the airflow passage 10a and finally flows out of the aerosol generating device for the user to smoke.

[0046] The airflow passage 10a and the main storage cavity 10b are isolated from each other, which is beneficial to prevent the aerosol generating substrate in the main storage cavity 10b from directly penetrating into the airflow passage 10a.

[0047] The main storage cavity 10b is used for the aerosol generating substrate.

[0048] Different main storage cavities 10b can store different types and flavors of aerosol generating substrates. For example, part of the main storage cavities 10b store different flavors of aerosol generating substrates, and part of the main storage cavities 10b store ice-type aerosol generating substrates.

[0049] The types of the plurality of atomization cores 12 can be the same or different, and different types of atomization cores 12 can make the generated aerosol have different tastes and flavors. For example, part of the atomization cores 12 are cotton core type atomization cores, and part of the atomization cores 12 are ceramic type atomization cores.

[0050] The additional storage cavity 20a is used to store the aerosol generating substrate, to supplement the consumption of the aerosol generating substrate in the main storage cavity 10b connected thereto, and to prolong the use time.

[0051] The airflow passages 10a of the plurality of atomization cores 12 are arranged in series along the first direction, that is, the airflow can continue to flow into the airflow passage 10a of another atomization core 12 after flowing out of the airflow passage 10a of one atomization core 12.

[0052] The liquid inlet 10c is located on one side of the main storage cavity 10b along the first direction, that is, the aerosol generating substrate in the additional storage cavity 20a flows into the main storage cavity 10b along the first direction.

[0053] The aerosol generating device in the embodiments of the present application has a plurality of atomization cores 12 and corresponding main storage cavities 10b, which are independent of each other, so that different types of atomization cores 12 and different types of aerosol generating substrates stored in different main storage cavities 10b can be installed, which is beneficial to generating aerosols with different tastes and flavors by using only one aerosol generating device, thereby enriching the user's choices; the airflow passages 10a of the plurality of atomization cores 12 are arranged in series along the first direction, which is beneficial to generating aerosols with mixed tastes and flavors, thereby further enriching the user's choices, and on the other hand, the plurality of atomization cores 12 share one total airflow passage, which is beneficial to making the structure more compact, reducing the resistance, improving the continuity of airflow flow, and improving the user's use experience.

[0054] It can be understood that the main storage cavities 10b corresponding to the atomization cores 12 arranged along the first direction are also arranged along the first direction.

[0055] In some embodiments, the airflow passage 10a penetrates the atomization core 12 to form an atomization cavity; in other embodiments, the atomization core 12 and other components in the atomization assembly 10 jointly enclose the airflow passage 10a.

[0056] The plurality of atomization cores 12 are arranged along the first direction, which can be that all the atomization cores 12 in the aerosol generating device are arranged along the first direction, or that part of the atomization cores 12 are arranged along the first direction.

[0057] In some embodiments, the additional oil tank 20 is detachably connected to the atomization assembly 10, so as to replace the additional oil tank 20 with depleted aerosol generating substrate, thereby reducing the user's use cost.

[0058] In some embodiments, the number of additional oil tanks 20 is one, which is beneficial to reducing the outer contour size of the aerosol generating device.

[0059] In some embodiments, the number of additional oil tanks 20 is multiple, so as to supplement the aerosol generating substrate to the plurality of main storage cavities 10b respectively, and improve the flexibility of use.

[0060] The number of additional oil tanks 20 can be the same as or different from the number of atomization cores 12.

[0061] In some embodiments in which the number of additional oil tanks 20 is multiple, referring to Figure 3 , each additional oil tank 20 is arranged along the first direction. In this way, it is beneficial to shorten the distance between each additional oil tank 20 and each main storage cavity 10b arranged along the first direction corresponding thereto, and improve the efficiency of the additional storage cavity 20a supplementing the aerosol generating substrate to the main storage cavity 10b.

[0062] In some embodiments in which the number of additional oil tanks 20 is multiple, referring to Figure 4 and Figure 7 , at least part of the additional oil tanks 20 is provided with a mounting cavity 20b penetrating along the first direction, and at least part of the atomization cores 12 is arranged in the mounting cavity 20b.

[0063] That is, the additional oil tank 20 is sleeved on the side of the axis of the atomization assembly 10 extending in the first direction.

[0064] In this way, in any direction perpendicular to the first direction, the atomization assembly 10 and the additional oil tank 20 are limited by each other, which is beneficial to improve the stability of the communication between the additional storage cavity 20a and the main storage cavity 10b.

[0065] In some embodiments, referring to Figure 4 and Figure 6 , one of the additional oil tank 20 and the mounting assembly 11 is provided with a plug-in column 111, and the other is provided with a plug-in hole 20c, the plug-in column 111 is provided with an exchange channel 111a, the exchange channel 111a communicates one of the additional storage cavity 20a and the main storage cavity 10b, the plug-in hole 20c communicates the other, the plug-in column 111 and the plug-in hole 20c both extend along the first direction and the plug-in column 111 is inserted into the plug-in hole 20c.

[0066] The exchange channel 111a communicates the additional storage cavity 20a and the main storage cavity 10b, and the inner wall of the plug-in hole 20c limits the plug-in column 111.

[0067] In this way, through the cooperation of the plug-in column 111 and the plug-in hole 20c, it is beneficial to limit the relative position of the additional oil tank 20 and the mounting assembly 11, facilitate the communication between the main storage cavity 10b and the additional storage cavity 20a, and reduce the risk of leakage of the aerosol generating substrate caused by the displacement between the main storage cavity 10b and the additional storage cavity 20a during use of the aerosol generating device.

[0068] It can be understood that, in some embodiments in which the installation assembly 11 is provided with the insertion post 111, one end of the exchange passage 111a is open to form the liquid inlet 10c of the main storage cavity 10b; in some embodiments in which the installation assembly 11 is provided with the insertion hole 20c, one end of the insertion hole 20c is open to form the liquid inlet 10c of the main storage cavity 10b.

[0069] One additional storage cavity 20a can be in communication with the main storage cavity 10b through one or more exchange passages 111a.

[0070] In some embodiments, referring to Figure 2 , Figure 3 and Figure 5 , the additional storage cavity 20a and the main storage cavity 10b in communication with each other form a group, and in a projection plane perpendicular to the first direction, the projection of the insertion hole 20c of one group is located outside the projection range of the insertion hole 20c of the other group.

[0071] That is, the additional storage cavity 20a and the main storage cavity 10b of the adjacent two groups are respectively arranged in the first direction.

[0072] In this way, the probability of interference between the insertion post 111 and the insertion hole 20c of the adjacent two groups is reduced, which is beneficial to reduce the overall outer contour size of the additional storage cavity 20 and the atomization assembly 10 in the first direction, and further reduce the overall contour size of the entire aerosol generating device, which is beneficial to improve portability.

[0073] In some embodiments, the insertion hole 20c is provided with a sealing plug, the sealing plug can block the insertion hole 20c to make the insertion hole 20c in a closed state, and the insertion post 111 can push the sealing plug away from the insertion hole 20c during the process of inserting the insertion hole 20c, so that the insertion hole 20c is converted from the closed state to the open state, and in the open state, the additional storage cavity 20a and the main storage cavity 10b are in communication through the exchange passage 111a. In this way, the risk of leakage of the aerosol generating substrate of the additional storage cavity 20 in the unused state is reduced by the sealing plug.

[0074] In the process of user inhaling aerosol, the first direction is generally along the direction of gravity.

[0075] In some embodiments, referring to Figure 3 and Figure 4The plurality of additional oil tanks 20 include a first oil tank 21, at least part of the first oil tank 21 is located on a side of one of the two atomization cores 12 adjacent in the first direction, which is perpendicular to the first direction and downstream of the two atomization cores 12 in the airflow flowing direction within the airflow passage 10a, and an additional storage cavity 20a of the first oil tank 21 is in communication with a main storage cavity 10b corresponding to the other atomization core 12 upstream of the airflow flowing direction.

[0076] That is, the additional storage cavity 20a in the first oil tank 21 and the main storage cavity 10b in communication therewith are arranged at least partially staggered in the first direction.

[0077] In this way, it is beneficial for the aerosol generating substrate in the additional storage cavity 20a of the first oil tank 21 to enter the main storage cavity 10b in communication therewith under the action of gravity as soon as possible during use of the aerosol generating device by the user, improving the efficiency of replenishing the aerosol generating substrate into the main storage cavity 10b and reducing the risk of dry burning of the atomization core 12 and other problems, and improving the user experience.

[0078] The number of the first oil tank 21 can be one or multiple, and all of the plurality of additional oil tanks 20 can be the first oil tank 21, or part of them can be the first oil tank 21.

[0079] In some embodiments, the additional storage cavity 20a in the first oil tank 21 and the main storage cavity 10b in communication therewith are completely staggered in the first direction.

[0080] In this way, it is beneficial for the aerosol generating substrate stored in the additional storage cavity 20a of the first oil tank 21 to enter the main storage cavity 10b under the action of gravity as much as possible.

[0081] In some embodiments, referring to Figure 5 and Figure 6 The plurality of additional oil tanks 20 further include a second oil tank 22, at least part of the second oil tank 22 is located on a side of the last atomization core 12 in the airflow flowing direction within the airflow passage 10a, which is away from other atomization cores 12 in the first direction, and an additional storage cavity 20a of the second oil tank 22 is in communication with a main storage cavity 10b corresponding to the last atomization core 12.

[0082] In this way, on the one hand, it is beneficial for the additional storage cavity 20a of the second oil tank 22 to provide the last main storage cavity 10b in the first direction with aerosol generating substrate more efficiently under the action of gravity, reducing the risk of dry burning of the corresponding atomization core 12 and other problems, and improving the user experience; on the other hand, it is also beneficial for reducing the size of the second oil tank 22 in the direction perpendicular to the first direction, and reducing the overall outer contour size of the aerosol generating device.

[0083] In some embodiments, referring to Figure 5 andFigure 6 The second oil reservoir 22 is provided with a transition air passage 22a, which penetrates the second oil reservoir 22 along the first direction, and one end of the transition air passage 22a is in communication with the airflow passage 10a of the last atomizing core 12 along the airflow flowing direction in the airflow passage 10a, and the other end is in communication with the outside of the aerosol generating device.

[0084] In this way, the airflow discharged from the last airflow passage 10a can enter the transition air passage 22a, and the flow direction of the airflow is directly constrained by the second oil reservoir 22, which is beneficial to reduce the number of components in the aerosol generating device, simplify the structure, and make the structure more compact.

[0085] In some embodiments, referring to Figure 3 The aerosol generating device further comprises a mouthpiece 30 provided with a through air discharge passage 30a, one end of the air discharge passage 30a is in communication with the transition air passage 22a of the second oil reservoir 22, and the other end is in communication with the outside of the aerosol generating device, and the mouthpiece 30 is used for user suction, so that the aerosol in each series airflow passage 10a ultimately enters the user's oral cavity through the transition air passage 22a and the air discharge passage 30a.

[0086] In some embodiments, a part of the outer surface of the additional oil reservoir 20 forms the outer contour surface of the aerosol generating device, and the structure between the part of the outer surface and the inner wall of the additional storage cavity 20a is made of a light-transmitting material, so that the user can see the remaining amount of the aerosol generating substrate in the additional storage cavity 20a.

[0087] In some embodiments, referring to Figure 4 The atomizing assembly 10 further comprises a center tube 13 located in the mounting space 11a, and the center tube 13 is provided with a through mounting passage 13a, and the atomizing core 12 is located in the mounting passage 13a.

[0088] The center tube 13 provides a mounting position for the atomizing core 12.

[0089] The center tube 13 is provided with a through liquid passage hole, and the liquid passage hole is in communication with the mounting passage 13a and the main storage cavity 10b. The atomizing core 12 covers the side opening of the liquid passage hole in communication with the mounting passage 13a, so that the atomizing core 12 can absorb the aerosol generating substrate entering the liquid passage hole.

[0090] It can be understood that the airflow passage 10a is located in the center tube 13.

[0091] In some embodiments, referring to Figure 4 The plurality of atomizing cores 12 comprises a plurality of first sub-cores 121, and the plurality of first sub-cores 121 are located in the mounting passage 13a.

[0092] Therefore, the plurality of first sub-wicks 121 can be installed into the installation space 11a of the center tube 13 at one time during the assembly of the atomization assembly 10, thereby improving the convenience of assembly and reducing the number of components and making the structure of the atomization assembly 10 more compact.

[0093] In some embodiments, the atomization wick 12 is fixed to the center tube 13 by adhesion.

[0094] The plurality of atomization wicks 12 can be a part of the first sub-wicks 121 or all of the first sub-wicks 121.

[0095] In some embodiments, referring to Figure 4 The installation assembly 11 includes an installation shell 112 and a sealing member 113. The installation shell 112 is provided with a containing cavity. The sealing member 113 is arranged in the containing cavity and is in sealing contact with the inner wall of the containing cavity, so as to divide the containing cavity into a plurality of installation spaces 11a. The sealing member 113 is provided with an installation through hole 113a penetrating through the sealing member 113. The installation through hole 113a communicates two adjacent installation spaces 11a.

[0096] Therefore, the containing cavity is divided into a plurality of installation spaces 11a in series and isolation by the sealing member 113, so that the airflow passages 10a of the plurality of atomization wicks 12 are in series communication with each other.

[0097] It can be understood that the installation through hole 113a communicates two airflow passages 10a, so as to realize the purpose of series connection of the two airflow passages 10a.

[0098] In some embodiments, the sealing member 113 is made of one of rubber and silica gel, so as to better realize the sealing of the installation space 11a by elastic deformation of the sealing member 113.

[0099] The number of the sealing member 113 can be one or a plurality.

[0118] In this way, after the aerosol generating substrate on the atomization core 12 is consumed to a certain extent, the liquid storage member 14 can supplement the aerosol generating substrate to the atomization core 12, so that the concentration of the aerosol generating substrate in the atomization core 12 is maintained within a certain range. At the same time, due to the presence of the pores, the airflow can also pass through the liquid storage member 14 through the pores in communication with each other. That is, the channels formed by the pores in the liquid storage member 14 in communication with each other allow airflow to pass through and allow the aerosol generating substrate to flow through.
