[0048] The embodiments of the present application provide an aerosol generating device for generating aerosol for a user to smoke.

[0049] Referring to Figure 1 , Figure 2 , Figure 9 , Figure 15 and Figure 17 , the aerosol generating device includes an atomization assembly 10 and a plurality of additional oil tanks 20.

[0050] The atomization assembly 10 includes a mounting cover 11, a mounting assembly 12, and an atomizer 13, the atomizer 13 is arranged in the mounting assembly 12 and cooperates with the mounting assembly 12 to form a main storage cavity 10b, the mounting cover 11 is located outside the mounting assembly 12 and is detachably connected with the mounting assembly 12, and the mounting cover 11 cooperates with the mounting assembly 12 to form a mounting space 10a.

[0051] The additional oil tank 20 is arranged in the mounting space 10a, and the additional storage cavity 20a can communicate with the main storage cavity 10b.

[0052] The main storage cavity 10b stores aerosol generating substrate, and the atomizer 13 can convert the aerosol generating substrate in the main storage cavity 10b into aerosol by heating or the like, and the aerosol is discharged from the aerosol generating device for the user to smoke.

[0053] The additional storage cavity 20a stores aerosol generating substrate.

[0054] In the state that the additional storage cavity 20a communicates with the main storage cavity 10b, the aerosol generating substrate in the additional storage cavity 20a can enter the main storage cavity 10b to supplement the consumption of the aerosol generating substrate in the main storage cavity 10b and increase the number of puffs of the aerosol generating device.

[0055] The mounting cover 11 and the mounting assembly 12 are detachably connected, so that after the aerosol generating substrate in at least part of the additional oil tank 20 is consumed or other problems such as blockage occur, the mounting cover 11 and the mounting assembly 12 are disassembled and the additional oil tank 20 is replaced, and then the mounting cover 11 and the mounting assembly 12 are reinstalled to restore the normal use of the aerosol generating device.

[0056] The aerosol-generating device in the embodiments of the present application is advantageous in increasing the total volume of the aerosol-generating substrate that can be stored in the aerosol-generating device, increasing the number of times of suction for the user, and in making each of the additional tanks 20 back up each other, so that the main storage chamber 10b can still be supplied with the aerosol-generating substrate in the case that some of the additional tanks 20 have problems, and in simultaneously supplying the main storage chamber 10b with different types of aerosol-generating substrate, improving the user experience. By providing the mounting space 10a, the additional tank 20 can be protected to some extent, and at the same time, the position of the additional tank 20 can be constrained and fixed, reducing the probability that the additional tank 20 and the atomization assembly 10 cannot be connected due to displacement during use.

[0057] The specific way in which the mounting cover 11 and the mounting assembly 12 are detachably connected is not limited.

[0058] For example, one of the mounting cover 11 and the mounting assembly 12 is provided with an elastic buckle, and the other is provided with a clamping groove. At least part of the elastic buckle can be embedded in the clamping groove or come out of the clamping groove through elastic deformation of the elastic buckle, so as to realize the fixing and separation between the mounting cover 11 and the mounting assembly 12.

[0059] In some embodiments, the total volume of the additional storage chambers 20a of all the additional tanks 20 is greater than the volume of the main storage chamber 10b, so as to improve the efficiency of supplementing the aerosol-generating substrate into the main storage chamber 10b and reduce the frequency of replacing the additional tank 20.

[0060] In some embodiments, the volume of the additional storage chamber 20a of a single additional tank 20 is greater than the volume of the main storage chamber 10b, so as to further improve the efficiency of supplementing the aerosol-generating substrate into the main storage chamber 10b and reduce the frequency of replacing the additional tank 20.

[0061] In some embodiments, referring to Figure 3 , Figure 4 and Figure 6 , one of the mounting assembly 12 and the additional tank 20 is externally provided with a plug-in column 121, and the other is provided with a plug-in channel 20b. The plug-in column 121 is provided with a fluid channel 121a, the fluid channel 121a communicates with one of the main storage chamber 10b and the additional storage chamber 20a, the plug-in channel 20b communicates with the other, and the plug-in column 121 can be inserted into the plug-in channel 20b to make the plug-in channel 20b communicate with the main storage chamber 10b and the additional storage chamber 20a.

[0062] Referring to Figure 6The installation assembly 12 can be provided with the insertion column 121, the insertion channel 20b is communicated with the main storage cavity 10b, the additional oil tank 20 is provided with the insertion channel 20b, and the fluid channel 121a is communicated with the additional storage cavity 20a. Alternatively, the installation assembly 12 can be provided with the insertion channel 20b, the fluid channel 121a is communicated with the main storage cavity 10b, the additional oil tank 20 is provided with the insertion column 121, and the insertion channel 20b is communicated with the additional storage cavity 20a.

[0063] The limiting action between the inner wall of the insertion channel 20b and the insertion column 121 plays a guiding and restraining role on the movement between the additional oil tank 20 and the installation assembly 12, facilitating the communication between the main storage cavity 10b and the additional storage cavity 20a, and reducing the difficulty of user operation. It is also conducive to reducing the probability that the additional oil tank 20 and the atomization assembly 10 cannot be communicated due to displacement during normal use of the aerosol generating device.

[0064] It can be understood that the speed of the atomizer 13 absorbing and converting the aerosol generating substrate into aerosol is limited. Therefore, it is necessary to limit the speed of the aerosol generating substrate in the main storage cavity from entering the atomizer 13, so as to reduce the probability that the aerosol generating substrate absorbed in the atomizer 13 is oversaturated and affects the user's smoking experience.

[0065] In some embodiments, referring to Figure 3 and Figure 10 The aerosol generating device further comprises a liquid storage member 30 capable of absorbing the aerosol generating substrate by capillary action, and at least one of the main storage cavity 10b and the additional storage cavity 20a is provided with the liquid storage member 30.

[0066] After the liquid storage member 30 contacts with the aerosol generating substrate, the aerosol generating substrate can be absorbed by the liquid storage member 30 and stored in the space in the pores by capillary action. At least part of the pores are communicated with each other, so that the aerosol generating substrate can flow to the area with lower content in the liquid storage member 30.

[0067] In this way, the adsorption and blocking of the aerosol generating substrate by the liquid storage member 30 can reduce the speed of supplementing the aerosol generating substrate to the atomizer 13 and reduce the probability of oversaturation of the aerosol generating substrate absorbed in the atomizer 13.

[0068] It can be understood that the pores of the liquid storage member 30 can be macroscopically identifiable pores or microscopically unidentifiable pores, as long as they meet the requirements of absorbing the aerosol generating substrate by capillary action and allowing airflow to pass through.

[0069] The specific form of the liquid storage member 30 is not limited, for example, a fiber structure woven or twisted from cotton, sponge, polyester, nylon, etc. It can also be a porous ceramic material.

[0070] In some embodiments in which the liquid storage member 30 is arranged in the main storage cavity 10b, the atomizer 13 is in fluid communication with the liquid storage member 30, so that the aerosol generating substrate in the liquid storage member 30 can flow directly to the atomizer 13.

[0071] In some embodiments, referring to Figure 10 The liquid storage member 30 is arranged in one of the main storage cavity 10b and the additional storage cavity 20a that is in communication with the fluid channel 121a, and the liquid storage member 30 covers the communication port of the one with the fluid channel 121a.

[0072] That is, in the embodiments in which the main storage cavity 10b is in communication with the fluid channel 121a, the aerosol generating substrate in the fluid channel 121a must pass through the liquid storage member 30 to enter the main storage cavity 10b; in the embodiments in which the additional storage cavity 20a is in communication with the fluid channel 121a, the aerosol generating substrate in the additional storage cavity 20a must pass through the liquid storage member 30 to enter the fluid channel 121a.

[0073] In this way, the aerosol generating substrate must pass through the liquid storage member 30 during the process of flowing from the additional storage cavity 20a to the atomizer 13, so that the aerosol generating substrate cannot flow directly to the atomizer 13, thereby facilitating better control of the speed of the additional aerosol generating substrate to the atomizer 13; at the same time, it is also beneficial to reduce the risk of the aerosol generating substrate overflowing or leaking to the outside during the process of disassembling and assembling the additional storage cavity 20.

[0074] In some embodiments, the fluid channel 121a is filled with the liquid storage member 30. In this way, it is beneficial to better control the speed of the additional aerosol generating substrate from the additional storage cavity 20a to the atomizer 13, and to reduce the risk of aerosol generating substrate leakage.

[0075] In some embodiments, the liquid storage member 30 is arranged in one of the main storage cavity 10b and the additional storage cavity 20a that is in communication with the insertion channel 20b, and the liquid storage member 30 covers the communication port of the one with the insertion channel 20b.

[0076] That is, in the embodiments in which the main storage cavity 10b is in communication with the insertion channel 20b, the aerosol generating substrate flows directly into the liquid storage member 30 after flowing out of the fluid channel 121a; in the embodiments in which the additional storage cavity 20a is in communication with the insertion channel 20b, the aerosol generating substrate in the additional storage cavity 20a must pass through the liquid storage member 30 to enter the fluid channel 121a.

[0077] Thus, in the process of the aerosol generating substrate flowing from the additional storage cavity 20a to the atomizer 13, the aerosol generating substrate has to pass through the liquid storage member 30, so that the aerosol generating substrate cannot directly flow to the atomizer 13, thereby facilitating better control of the speed of the additional aerosol generating substrate to the atomizer 13; at the same time, it is also beneficial to reduce the risk of the aerosol generating substrate in one of the main storage cavity 10b and the additional storage cavity 20a communicated with the plug-in channel 20b overflowing or leaking to the outside during the disassembly and assembly of the additional oil tank 20.

[0078] In some embodiments, in the state that the additional storage cavity 20a is communicated with the main storage cavity 10b, a part of the plug-in column 121 can be inserted into the liquid storage member 30 in one of the main storage cavity 10b and the additional storage cavity 20a communicated with the plug-in channel 20b. Thus, the aerosol generating substrate in the liquid storage member 30 can enter the fluid channel 121a.

[0079] In some embodiments, referring to Figure 4 , Figure 5 , Figure 11 and Figure 12 , the plug-in channel 20b is provided with a sealing film 21, and the sealing film 21 is used to block the plug-in channel 20b. The plug-in column 121 can break through the sealing film 21 to communicate the additional storage cavity 20a with the main storage cavity 10b.

[0080] It can be understood that the aerosol generating substrate cannot penetrate through the sealing film 21.

[0081] Thus, it is beneficial to reduce the risk of the aerosol generating substrate in the additional storage cavity 20a and the main storage cavity 10b leaking before the additional oil tank 20 and the atomization assembly 10 are used for the first time, thereby facilitating the transportation and storage of the additional oil tank 20 and the atomization assembly 10.

[0082] The specific material of the sealing film 21 is not limited, such as an aluminum plastic film, a plastic sealing film, etc.

[0083] In some embodiments, referring to Figure 6 and Figure 10 , the end of the plug-in column 121 is provided with at least one pointed end 1211, which gradually shrinks away from the additional oil tank 20 or the atomizer 13 provided with the plug-in part along the extension direction of the plug-in column 121. Thus, it is more beneficial to break through the sealing film 21 through the pointed end 1211.

[0084] In some embodiments, referring to Figure 13 and Figure 14 , the aerosol generating device further comprises a sealing plug 40, which is used to block the fluid channel 121a. That is, the fluid channel 121a is in a blocked state.

[0085] The fluid passage 121a comprises a blocked state and a communicated state. The blocked state of the fluid passage 121a refers to a state in which the sealing plug 40 blocks the fluid passage 121a, and the aerosol generating substrate cannot pass through the fluid passage 121a. In this state, the sealing plug 40 is in the first position range relative to the insertion column 121.

[0086] The communicated state of the fluid passage 121a, referring to Figure 15 and Figure 16 , refers to a state in which the sealing plug 40 no longer blocks the fluid passage 121a, and the aerosol generating substrate can pass through the fluid passage 121a. In this state, the sealing plug 40 is in the second position range relative to the insertion column 121.

[0087] In this way, it is beneficial to reduce the risk of leakage of the aerosol generating substrate during transportation and storage of the additional tank 20 or the atomizer 13 provided with the fluid passage 121a.

[0088] The specific way in which the sealing plug 40 blocks the fluid passage 121a is not limited, for example, referring to Figure 14 , a portion of the sealing plug 40 is located in the fluid passage 121a and sealingly fits the inner wall of the fluid passage 121a.

[0089] It can be understood that during use of the aerosol generating device by a user, the sealing plug 40 needs to be moved first to change the fluid passage 121a from the blocked state to the communicated state.

[0090] In some embodiments provided with the sealing plug 40 and the sealing film 21, referring to Figures 14 to 16 , in the state in which the sealing plug 40 blocks the fluid passage 121a, a portion of the sealing plug 40 protrudes from the insertion column 121 for insertion into one end of the insertion passage 20b, so that during insertion of the insertion column 121 into the insertion passage 20b, the sealing plug 40 abuts against the sealing film 21 before the insertion column 121 and drives the sealing film 21 to move the sealing plug 40, so as to switch the fluid passage 121a from the blocked state to the communicated state.

[0091] In the state in which the sealing plug 40 blocks the fluid passage 121a, the main storage cavity 10b and the additional storage cavity 20a are not communicated, and the atomizer assembly 10 or the additional tank 20 can be realized for separate storage and transportation. In this state, a portion of the sealing plug 40 protrudes from the fluid passage 121a away from the side opening of the additional storage cavity 20a or the main storage cavity 10b.

[0092] In the process of inserting the insertion column 121 into the insertion channel 20b, the sealing plug 40 is in contact with the sealing film 21 and cannot break the sealing film 21, the insertion column 121 continues to move relative to the insertion channel 20b, the sealing film 21 exerts a force on the sealing plug 40, so that the sealing plug 40 moves in the fluid channel 121a and moves from the first position range to the second position range, and the fluid channel 121a switches from the blocked state to the connected state.

[0093] It can be understood that, in the connected state of the fluid channel 121a, the insertion column 121 breaks the sealing film 21.

[0094] Therefore, in the process of inserting the insertion column 121 into the insertion channel 20b, the insertion channel 20b and the fluid channel 121a can be connected, which is beneficial to simplify the operation of the user and improve the convenience of use.

[0095] The specific material of the sealing plug 40 is not limited, for example, rubber, silica gel, etc.

[0096] In some embodiments provided with the sealing plug 40, referring to Figure 15 and Figure 16 , the aerosol generating device further comprises a stopper 22, one of the atomizer 13 and the additional oil reservoir 20 provided with the insertion channel 20b is provided with the stopper 22, in the process of inserting the insertion column 121 into the insertion channel 20b, the stopper 22 can abut against the sealing plug 40 in the insertion direction of the insertion column 121 and drive the sealing plug 40 to move, so that the fluid channel 121a switches from the blocked state to the connected state.

[0097] That is, in the process of inserting the insertion column 121 into the insertion channel 20b, the stopper 22 abuts against the sealing plug 40, and with the relative movement of the insertion column 121 and the insertion channel 20b, the sealing plug 40 is subjected to a force, so that the sealing plug 40 moves in the fluid channel 121a and moves from the first position range to the second position range, and the fluid channel 121a switches from the blocked state to the connected state.

[0098] Therefore, in the process of inserting the insertion column 121 into the insertion channel 20b, the fluid channel 121a can be connected, which is beneficial to simplify the operation of the user and improve the convenience of use.

[0099] In some embodiments provided with the stopper 22, in the connected state, some embodiments, referring to Figure 15 , the stopper 22 is completely located inside one of the main storage cavity 10b and the additional storage cavity 20a which is in communication with the insertion channel 20b; in some other embodiments, a part of the stopper 22 is inserted into the inside of the insertion channel 20b.

[0100] In some embodiments, referring to Figure 15The linear direction in which the insertion direction of the insertion post 121 of the insertion channel 20b is located is a first direction, and the stopper 22 is a columnar structure extending along the first direction. In this way, it is beneficial to directly form the stopper 22 by stripping along the first direction during the process of injection molding the stopper 22, which is beneficial to simplify the manufacturing process.

[0101] In some examples provided with the stopper 22, referring to Figure 15 and Figure 16 The aerosol generating device further comprises an elastic member 50, one of the atomizer 13 and the additional oil reservoir 20 provided with the fluid channel 121a is provided with the elastic member 50, and the sealing plug 40 drives the elastic member 50 to produce elastic deformation during the process of inserting the insertion post 121 into the insertion channel 20b, so as to make the sealing plug 40 have a movement tendency of plugging the fluid channel 121a.

[0102] During the process of inserting the insertion post 121 into the insertion channel 20b, the stopper 22 pushes the sealing plug 40 to move, and the sealing plug 40 synchronously drives the elastic member 50 to produce elastic deformation and accumulate elastic potential energy. During the process of replacing the additional oil reservoir 20, the insertion post 121 is pulled out of the insertion channel 20b, the stopper 22 is out of contact with the sealing plug 40, and the elastic potential energy of the elastic member 50 is released to push the sealing plug 40 to move and re-plug the fluid channel 121a.

[0103] In this way, in the case that the fluid channel 121a communicates with the main storage cavity 10b, it is beneficial to reduce the probability of foreign matter entering the inside of the main storage cavity 10b during the process of replacing the additional oil reservoir 20, and reduce the risk of leakage of the aerosol generating substrate remaining in the main storage cavity 10b; in the case that the fluid channel 121a communicates with the additional storage cavity 20a, it is beneficial to reduce the risk of leakage of the aerosol generating substrate in the replaced additional oil reservoir 20.

[0104] In some embodiments, referring to Figure 16 The elastic member 50 is located inside one of the additional storage cavity 20a and the main storage cavity 10b which communicates with the fluid channel 121a, so as to reduce the adverse interference of the outside to the elastic deformation of the elastic member 50.

[0105] The specific type of the elastic member 50 is not limited, and an example is that, referring to Figure 16 The linear direction in which the insertion direction of the insertion post 121 of the insertion channel 20b is located is a first direction, the elastic member 50 is a spring, the spring can stretch and contract along the first direction, one end of the spring along the first direction abuts against the sealing plug 40, and the inner wall of one of the additional storage cavity 20a and the main storage cavity 10b which communicates with the fluid channel 121a abuts against the other end of the spring.

[0106] In some embodiments, referring to Figure 2 , Figures 6 to 8The mounting assembly 12 comprises a main body portion 122 and a column portion 123, the column portion 123 is arranged at one side end of the main body portion 122 along the first direction, the additional oil tank 20 is arranged perpendicularly to the first direction with the column portion 123, and at least part of the additional oil tank 20 is located at one side of the main body portion 122 along the first direction.

[0107] In this way, the column portion 123 can limit the additional oil tank 20 perpendicularly to the first direction, and the main body portion 122 can limit the additional oil tank 20 along the first direction.

[0108] In some embodiments, a plurality of additional oil tanks 20 are arranged around the column portion 123, and the axis of the arrangement extends along the first direction, so that the column portion 123 can limit the plurality of additional oil tanks 20.

[0109] In some embodiments, referring to Figure 2 The mounting cover 11 is provided with a first air outlet channel 11a penetrating through the mounting cover 11, the first air outlet channel 11a is in communication with the outside of the aerosol generating device, and the atomizer 13 is provided with an atomization cavity 13a, the atomization cavity 13a is in communication with the first air outlet channel 11a. The aerosol generated by the atomizer 13 enters the atomization cavity 13a and is discharged to the outside of the aerosol generating device through the first air outlet channel 11a for the user to smoke.

[0110] The specific way in which the atomization cavity 13a is in communication with the first air outlet channel 11a is not limited.

[0111] In some embodiments provided with the first air outlet channel 11a and the atomization cavity 13a, referring to Figure 2 and Figure 8 The atomizer 13 is arranged in the main body portion 122, and the column portion 123 is provided with a second air outlet channel 123a, the second air outlet channel 123a is in communication with the first air outlet channel 11a and the atomization cavity 13a.

[0112] That is, the column portion 123 is a hollow structure, forming a fluid medium flow path of the atomization cavity 13a→the second air outlet channel 123a→the first air outlet channel 11a.

[0113] In this way, the column portion 123 can realize the function of conveying aerosol, make use of the space of the column portion 123 itself, improve the space utilization rate, and facilitate the structure of the aerosol generating device to be more compact; facilitate the extension of the conveying path length of the aerosol in the aerosol generating device, and facilitate the cooling of the aerosol.

[0114] In other embodiments provided with the first air outlet channel 11a and the atomization cavity 13a, referring to Figure 9 and Figure 10 The atomizer 13 is arranged in the column portion 123, and the first air outlet channel 11a is in communication with the atomization cavity 13a and the outside of the aerosol generating device.

[0115] Thus, the size of the aerosol-generating device along the first direction is shortened, and the portability of the aerosol-generating device is improved. The length of the conveying path of the aerosol in the aerosol-generating device is shortened, and the amount of condensation of the aerosol in the aerosol-generating device is reduced.

[0116] It can be understood that the mounting cover 11 is provided with a suction nozzle, and the outlet of the first air outlet channel 11a is located on the suction nozzle for a user to suck.

[0117] In some embodiments in which the atomizer 13 is arranged in the columnar portion 123, referring to Figure 10 , the insertion direction of the insertion column 121 inserted into the insertion channel 20b is perpendicular to the first direction. Thus, the length of the flow path of the aerosol in the additional storage cavity 20a into the main storage cavity 10b is shortened, and the speed of supplementing the aerosol-generating substrate into the main storage cavity 10b is improved.

[0118] In some embodiments, the number of the main storage cavities 10b is one, and each of the plurality of additional storage cavities 20a is in communication with the main storage cavity 10b.

[0119] In some embodiments, referring to Figure 17 and Figure 18 , the number of the main storage cavities 10b is a plurality and corresponds to the number of the additional storage cavities 20, and the atomizer 13 is provided with a plurality of liquid inlet channels 13d, and each of the main storage cavities 10b is in communication with at least one of the liquid inlet channels 13d.

[0120] Thus, in the case that some of the main storage cavities 10b and the liquid inlet channels 13d are blocked, the other main storage cavities 10b and the liquid inlet channels 13d can normally function, and the service life of the aerosol-generating device is prolonged.

[0121] In some embodiments, referring to Figure 18 , the atomizer 13 comprises a mounting seat 131 and an atomizing core 132. The mounting seat 131 is provided with a mounting cavity and a liquid inlet channel 13d. The atomizing core 132 is arranged in the mounting cavity and is in sealing contact with the inner wall of the mounting cavity to divide the mounting cavity into a first sub-cavity 13b and a second sub-cavity 13c. The first sub-cavity 13b is in communication with the liquid inlet channel 13d, and the second sub-cavity 13c is in communication with the first air outlet channel 11a.

[0122] The atomizing core 132 can convert the aerosol-generating substrate in contact with the atomizing core 132 into an aerosol by heating or the like.

[0123] Thus, the aerosol-generating substrate in each of the liquid inlet channels 13d can enter the first sub-cavity 13b and contact the atomizing core 132.
