Description

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese patent applications No. 202422054774.4, filed on August 22, 2024, entitled "An Additional Oil Tank and Aerosol Generating Device" and No. 202421629187.7, filed on July 10, 2024, entitled "Electronic Atomizing Device and Atomizer", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, specifically to an aerosol generating device. Background Technology

[0004] Aerosol generating devices are used to generate aerosols for users to inhale.

[0005] The aerosol generating device includes an atomizer and an auxiliary oil tank. The reservoir in the atomizer absorbs the aerosol generating matrix and converts it, delivering it to the atomizing core. The atomizing core then converts the aerosol generating matrix into aerosol. When the aerosol generating matrix in the atomizer is depleted to a certain extent, the aerosol generating matrix stored in the auxiliary oil tank enters the atomizer through its outlet to replenish it, thereby extending the service life of the aerosol generating device.

[0006] It is understandable that the amount of aerosol generating matrix that the reservoir can absorb is limited. If too much aerosol generating matrix from the auxiliary oil tank enters the atomizer or is replenished too quickly, it can easily lead to oversaturation of the aerosol generating matrix stored in the reservoir, which in turn will adversely affect the taste of the aerosol formed by the atomizing coil.

[0053] DETAILED DESCRIPTION

[0054] It should be noted that the technical features in the embodiments of the present application can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation of the purpose of the embodiments of the present application, and should not be regarded as an improper limitation of the embodiments of the present application.

[0055] ​​​In the description of the embodiments of this utility model, the orientation or positional relationship of the "first direction" is based on the orientation or positional relationship shown by arrow X in the accompanying drawings, wherein x1 represents one direction of the direction and x2 represents another direction of the direction; the orientation or positional relationship of the "second direction" is based on the orientation or positional relationship shown by arrow Y in the accompanying drawings.

[0056] It should be understood that these directional terms are only for the convenience of describing the embodiments of the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of the present invention.

[0057] This application provides an aerosol generating device for forming an aerosol from an aerosol generating matrix through heating or other means for users to inhale.

[0058] See Figures 1 to 4 , Figures 11 to 14 , Figures 21 to 23 The aerosol generating device includes an atomizer 10 and an auxiliary oil tank 20.

[0059] The atomizer 10 includes an atomizing component 11 and a liquid storage component 12. The atomizing component 11 includes a main storage chamber 10a. The liquid storage component 12 is located inside the main storage chamber 10a. The main storage chamber 10a has a main communication port 10d on the inner wall of the first side along the first direction.

[0060] The auxiliary oil tank 20 includes an auxiliary storage cavity 20a, and the inner wall of the auxiliary storage cavity 20a is provided with an auxiliary communication port 20c.

[0061] A portion of one of the atomizer 10 and the auxiliary oil tank 20 is movable relative to the other to switch between a connected state and a sealed state. In the connected state, at least a portion of the auxiliary storage chamber 20a is arranged with the main storage chamber 10a along a second direction, and the auxiliary connection port 20c is located on the inner wall of the portion of the auxiliary storage chamber 20a along a first direction close to the main connection port 10d. The first direction is perpendicular to the second direction. The main connection port 10d and the auxiliary connection port 20c are used for the auxiliary storage chamber 20a to connect with the main storage chamber 10a. In the sealed state, the auxiliary storage chamber 20a is isolated from the main storage chamber 10a.

[0062] The atomizing component 11 includes an atomizing core 111, which is used to absorb the aerosol generating matrix in the main storage chamber 10a and convert the aerosol generating matrix into aerosol by means of heating or other methods.

[0063] The liquid storage member 12 is provided with pores to be able to absorb at least part of the aerosol generating substrate in the main storage cavity 10a by capillary action, and is in fluid communication with the atomization assembly 11 to enable the aerosol generating substrate to flow from one to the other. The specific manner of achieving fluid communication between the two is not limited, such as direct contact between the two, or a channel is provided between the two to enable fluid to pass through the channel to achieve contact with the two.

[0064] After the liquid storage member 12 is in contact with the aerosol generating substrate, the aerosol generating substrate can be absorbed by the liquid storage member 12 and stored in the space in the pores by capillary action; at least part of the pores are in communication with each other so that the aerosol generating substrate can be transported through the liquid storage member 12 to the atomization core 111 of the atomization assembly 11 in fluid communication with the liquid storage member 12.

[0065] The main storage cavity 10a is provided with a main communication port 10d on the inner wall of one side in the first direction, which means that the vertical bisector between the two points farthest apart in the first direction of the main storage cavity 10a is located on one side of the main communication port 10d in the first direction. The geometric center of the main communication port 10d and one of the two points farthest apart in the first direction of the main storage cavity 10a are farther apart than the other.

[0066] The additional oil compartment 20 includes a communication state and a sealed state.

[0067] In the communication state, the additional storage cavity 20a is in communication with the main storage cavity 10a, so that the aerosol generating substrate in the additional storage cavity 20a can enter the main storage cavity 10a to supplement the consumption of the aerosol generating substrate in the main storage cavity 10a.

[0068] In the sealed state, the aerosol generating substrate in the additional storage cavity 20a is difficult to flow out of the additional storage cavity 20a.

[0069] The additional communication port 20c is located on the inner wall of one side of the additional storage cavity 20a in the first direction close to the main communication port 10d, which means that the vertical bisector between the two points farthest apart in the first direction of the additional storage cavity 20a is located on one side of the additional communication port 20c in the first direction. The geometric center of the additional communication port 20c and one of the two points farthest apart in the first direction of the additional storage cavity 20a are farther apart than the other.

[0070] Referring to Figure 4 , Figure 14 and Figure 23In the communicating state, at least part of the aerosol generating substrate needs to move along a first direction of a first orientation towards the additional communicating port 20c, and after entering the main storage cavity 10a, these aerosol generating substrates need to flow along a second orientation of the first direction to other parts of the main storage cavity 10a. The first orientation is opposite to the second orientation. Therefore, during the process of these aerosol generating substrates from the additional storage cavity 20a to the main storage cavity 10a, the flow direction needs to be reversed by approximately 180°.

[0071] It should be noted that the first orientation and the second orientation refer to two orientations of the first direction opposite to each other, rather than each representing a specific orientation. For example, referring to Figure 3 and Figure 13 , if x1 represents the first orientation, x2 represents the second orientation; for another example, referring to Figure 23 , if x1 represents the second orientation, x2 represents the first orientation.

[0072] The aerosol generating device in the embodiments of the present application, on the one hand, through the liquid storage member 12, it can first absorb the aerosol generating substrate entering the main storage cavity 10a, and then release the aerosol generating substrate to the atomization assembly 11, which is conducive to limiting the speed of supplementing the aerosol generating substrate to the atomization assembly 11, and reducing the probability of affecting the taste of the aerosol inhaled by the user when at least part of the atomization assembly 11 is immersed in the aerosol generating substrate; on the other hand, in the communicating state, at least part of the aerosol generating substrate needs to move along one orientation of the first direction towards the additional communicating port 20c, and after entering the main storage cavity 10a, these aerosol generating substrates need to flow along another orientation of the first direction to other parts of the main storage cavity 10a, so that at least part of the aerosol generating substrate reverses the flow direction during the flow process from the additional storage cavity 20a to the main storage cavity 10a, which delays the flow speed of the aerosol generating substrate, further conducive to controlling the speed of supplementing the aerosol generating substrate to the atomization assembly 11, and the additional communicating port 20c is located on the side of the additional storage cavity 20a close to the main communicating port, which is conducive to shortening the flow path of the aerosol generating substrate between the main communicating port 10d and the additional communicating port 20c, and improving the efficiency of supplementing the aerosol generating substrate into the main storage cavity 10a.

[0073] It can be understood that one part of the atomizer 10 can move relative to the other part to switch between the communicating state and the sealed state; or one part of the additional oil store 20 can move relative to the other part to switch between the communicating state and the sealed state.

[0074] It can be understood that the pores of the liquid storage member 12 can be macroscopically identifiable holes that can be identified by the naked eye, or microscopically unidentifiable holes that cannot be identified by the naked eye, as long as they meet the requirements of absorbing the aerosol generating substrate by capillary action and allowing airflow to pass through.

[0075] The specific form of the liquid storage member 12 is not limited, such as cotton, sponge, polyester, nylon, and other chemical fibers woven, twisted into a fiber structure, etc.

[0076] It can be understood that the aerosol generating substrate is infiltrated with the liquid relative to the material of the first liquid storage member 12, so that the aerosol generating substrate is attached or absorbed to the first liquid storage member 12.

[0077] In the communication state, the communication can be achieved through the channel formed by the atomizer 10 and the additional oil tank 20 between the main communication port 10d and the additional communication port 20c; it can be that a part of the additional oil tank 20 is inserted into the main storage cavity 10a through the main communication port 10d, so that the additional communication port 20c is communicated with the main storage cavity 10a through the channel of the additional oil tank 20; it can also be that a part of the atomizer 10 is inserted into the additional storage cavity 20a through the additional communication port 20c, so that the main communication port 10d is communicated with the additional storage cavity 20a through the channel of the atomizer 10.

[0078] In some embodiments, in the communication state, the main communication port 10d is located on the inner wall of the main storage cavity 10a on the side perpendicular to the first direction, and the additional communication port 20c is located on the inner wall of the additional storage cavity 20a on the side perpendicular to the first direction.

[0079] Along the first direction, the space in the additional storage cavity 20a is divided into a first part and a second part with the geometric center of the additional communication port 20c as the boundary, and the volume of the first part is greater than that of the second part; along the first direction, the space in the main storage cavity 10a is divided into a third part and a fourth part with the geometric center of the main communication port 10d as the boundary, and the volume of the third part is greater than that of the fourth part. And the first part and the third part are located on the same side along the first direction. The aerosol generating substrate in the first part needs to move towards the additional communication port 20c along the first direction of the first direction, and after entering the main storage cavity 10a, the aerosol generating substrate needs to flow to the third part along the first direction of the second direction.

[0080] In some embodiments, referring to Figure 14 and Figure 17 , the main communication port 10d is located on the inner wall of one end of the main storage cavity 10a along the first direction.

[0081] In this way, it is beneficial to make more aerosol generating substrates entering the main storage cavity 10a need to flow in the opposite direction, which further helps to slow down the speed of the aerosol generating substrate supplementing into the main storage cavity 10a as a whole.

[0082] In some embodiments, referring to Figure 4 and Figure 10The additional communication port 20c is located on the inner wall of one end of the additional storage cavity 20a along the first direction.

[0083] In this way, more of the aerosol generating substrate entering the main storage cavity 10a needs to flow in the reverse direction, which further slows down the speed of the aerosol generating substrate replenishing into the main storage cavity 10a as a whole.

[0084] In some embodiments, referring to Figures 1 to 3 , Figure 7 , Figures 11 to 13 , Figure 17 , Figures 21 to 23 , Figure 26 The atomization assembly 11 includes an air outlet passage 10b that is isolated from the main storage cavity 10a and communicates with the outside of the aerosol generating device.

[0085] The air outlet passage 10b is used to discharge the aerosol formed by the atomizer 10. During the user's inhalation of the aerosol, the aerosol enters the user's oral cavity through the outlet of the air outlet passage 10b.

[0086] The air outlet passage 10b is separated from the main storage cavity 10a, so that the aerosol generating substrate in the main storage cavity 10a cannot enter the air outlet passage 10b and leak.

[0087] In some embodiments, referring to Figures 1 to 3 , Figure 7 , Figures 11 to 13 , Figure 17 , Figures 21 to 23 , Figure 26 The air outlet passage 10b extends along the first direction, and the extension direction of the air outlet passage 10b is a straight line direction, which is beneficial to reduce the resistance of the user during the inhalation of the aerosol, and also beneficial to reduce the probability of condensate being formed in the air outlet passage 10b due to the reduction of the flow rate of the aerosol.

[0088] It can be understood that during the user's inhalation of the aerosol, the first direction is generally along the vertical direction, and the outlet of the air outlet passage 10b faces upward.

[0089] In some embodiments in which the air outlet passage 10b extends along the first direction, referring to Figure 3 , Figure 7 , Figure 13 and Figure 17 The main communication port 10d is located on the side of the main storage cavity 10a close to the outlet of the air outlet passage 10b.

[0090] That is, the additional communication port 20c is located on the side of the additional storage cavity 20a close to the outlet of the air outlet passage 10b.

[0091] Thus, during the user's puffing, the main communication port 10d is located at the top side of the main storage cavity 10a, and the additional communication port 20c is located at the top side of the additional storage cavity 20a. Since the aerosol generating substrate in the additional storage cavity 20a is deposited downward under the action of gravity, more aerosol generating substrate is difficult to enter the main storage cavity 10a through the main communication port 10d and the additional communication port 20c, thereby facilitating the control of the speed and quantity of the aerosol generating substrate replenished into the main storage cavity 10a.

[0092] It can be understood that, in the case that the user does not use the aerosol production device, the outlet of the air outlet channel 10b can be directed downward by inverting the aerosol production device, so that the main communication port 10d is located at the bottom side of the main storage cavity 10a, and the additional communication port 20c is located at the bottom side of the additional storage cavity 20a. Under the action of gravity, the aerosol generating substrate can enter the main storage cavity 10a.

[0093] It can be understood that, in the case that the user continuously puffs the aerosol, the aerosol generating substrate in the main storage cavity 10a is rapidly consumed, which is likely to cause the risk of dry burning of the atomization assembly 11.

[0094] During the user's puffing, at least part of the additional storage cavity 20a is located on one side of the main storage cavity 10a along the horizontal direction, which is beneficial to reduce the height difference between the top wall of the main storage cavity 10a and the top wall of the additional storage cavity 20a along the first direction, thereby reducing the difference in gravitational potential energy between the aerosol generating substrate in the additional storage cavity 20a and the aerosol generating substrate in the main storage cavity 10a, and reducing the kinetic energy of the aerosol generating substrate in the additional storage cavity 20a flowing into the main storage cavity 10a, thereby achieving the purpose of controlling the flow rate of the aerosol generating substrate.

[0095] In other embodiments in which the air outlet channel 10b extends along the first direction, referring to Figure 23 , the main communication port 10d is located on the side of the main storage cavity 10a away from the outlet of the air outlet channel 10b.

[0096] That is, the additional communication port 20c is also located on the side of the additional storage cavity 20a away from the outlet of the air outlet channel 10b.

[0097] Thus, during the user's puffing, more aerosol generating substrate can be replenished into the main storage cavity under the action of gravity, which is beneficial to reduce the problem of dry burning of the atomizer 10 and improve the user's experience.

[0098] It can be understood that the aerosol generating substrate in the additional storage cavity 20a has more gravitational potential energy than the aerosol generating substrate in the main storage cavity 10a, so as to convert the gravitational potential energy into kinetic energy of the aerosol generating substrate in the additional storage cavity 20a flowing into the main storage cavity 10a.

[0099] In some embodiments, referring to Figures 5 to 7 The atomization assembly 11 further includes a main passage 10c that is in communication with the main storage cavity 10a to form a main communication port 10d.

[0100] The main passage 10c is in communication with the outside of the atomizer 10.

[0101] In some embodiments, at least a portion of the main passage 10c is located on a side of the main storage cavity 10a that is closer to the additional storage cavity 20a in the second direction, so as to facilitate shortening the length of the main passage 10c.

[0102] In some embodiments, referring to Figure 9 , Figure 10 , Figure 19 , Figure 20 , Figure 24 and Figure 25 The additional oil tank 20 further includes an additional passage 20b that is in communication with the additional storage cavity 20a to form an additional communication port 20c.

[0103] The additional passage 20b is in communication with the outside of the additional oil tank 20.

[0104] In some embodiments, at least a portion of the additional passage 20b is located on a side of the additional storage cavity 20a that is closer to the main storage cavity 10a in the second direction, so as to facilitate shortening the length of the additional passage 20b.

[0105] In some embodiments provided with the main passage 10c and the additional passage 20b, referring to Figures 2 to 4 , Figures 12 to 14 A portion of one of the main storage cavity 10a and the additional storage cavity 20a is offset from the other in the first direction, and at least a portion of at least one of the main passage 10c and the additional passage 20b is projected in the projection of the portion of the main storage cavity 10a and the additional storage cavity 20a that is offset from each other in a projection plane that is perpendicular to the second direction.

[0106] The main passage 10c and the additional passage 20b together form a passage for the aerosol-generating substrate to flow through, so as to achieve the communication between the main storage cavity 10a and the additional storage cavity 20a.

[0107] A portion of one of the main storage cavity 10a and the additional storage cavity 20a is offset from the other in the first direction. That is, in the first direction, a portion of one of the main storage cavity 10a and the additional storage cavity 20a protrudes from the other, and a portion of the main storage cavity 10a is projected in the projection of the additional storage cavity 20a in a projection plane that is perpendicular to the second direction.

[0108] At least part of the projection of at least one of the main channel 10c and the additional channel 20b is located in the projection of the main storage cavity 10a and the additional storage cavity 20a being staggered from each other by a portion, which is conducive to shortening the distance between the main communication port 10d and the additional communication port 20c, and further conducive to shortening the total length of the main channel 10c and the additional channel 20b, and conducive to reducing the residual of the aerosol generating substrate in the main channel 10c and the additional channel 20b.

[0109] In some embodiments, referring to Figure 4 and Figure 14 , the main channel 10c includes a first sub-channel 10ca and a second sub-channel 10cb in communication with each other, the first sub-channel 10ca is in communication with the main storage cavity 10a to form the main communication port 10d, and the second sub-channel 10cb is in communication with the additional channel 20b.

[0110] It can be understood that, in order to adapt to the design requirements of sealing, electrical conduction, and arrangement of the liquid storage member 12 in the atomizer 10, the structure in the atomizer 10 is more complex than that of the additional oil compartment 20. The extension direction of the first sub-channel 10ca is different from that of the second sub-channel 10cb, which is conducive to avoiding the arrangement of other devices in the atomizer 10 and improving the space utilization rate in the atomizer 10.

[0111] In some embodiments, referring to Figure 4 and Figure 7 , Figure 9 and Figure 10 , in the communication state, the first sub-channel 10ca extends along the second direction, the additional channel 20b and the second sub-channel 10cb both extend along the first direction, the second sub-channel 10cb, the additional channel 20b, and the additional storage cavity 20a are arranged along the first direction in sequence, and the second sub-channel 10cb is located on the side of the first sub-channel 10ca along the first direction close to the additional storage cavity 20a.

[0112] The aerosol generating substrate in the additional storage cavity 20a flows into the additional channel 20b along the first direction, and then continues to flow into the second sub-channel 10cb along the first direction, and then turns into the first sub-channel 10ca, and flows into the main storage cavity 10a from the first sub-channel 10ca along the second direction. Part of the aerosol generating substrate entering the main storage cavity 10a flows to other parts of the main storage cavity 10a along the second direction.

[0113] In this way, it is conducive to further shortening the total length of the main channel 10c and the additional channel 20b, and conducive to making the outline of the atomizer 10 and the additional oil compartment 20 more compact.

[0114] It can be understood that the main communication port 10d is located on the inner wall of the side of the first protruding portion 10aa along the second direction close to the additional storage cavity 20a.

[0115] In some embodiments, referring to Figure 4 and Figure 7 , the main storage cavity 10a comprises a first protruding portion 10aa protruding from one end of the main storage cavity 10a along the first direction, the first protruding portion 10aa being in communication with the first sub-channel 10ca.

[0116] In some embodiments, in a projection plane perpendicular to the second direction, the projection of the main channel 10c and the projection of the additional channel 20b are both located within the projection range of the first protruding portion 10aa, so as to reduce the amount of aerosol generating substrate remaining in the main channel 10c.

[0117] In some embodiments, referring to Figure 13 , Figure 14 , Figure 16 , Figure 17 and Figure 20 , in the communication state, the additional channel 20b and the second sub-channel 10cb both extend along the second direction, the second sub-channel 10cb, the additional channel 20b and the additional storage cavity 20a are arranged in sequence along the second direction, the first sub-channel 10ca extends along the first direction, and the first sub-channel 10ca is located on the side of the second sub-channel 10cb close to the main storage cavity 10a along the first direction.

[0118] Part of the aerosol generating substrate in the additional storage cavity 20a flows along the first direction in a first direction, turns and then continues to flow into the additional channel 20b along the second direction, and then enters the second sub-channel 10cb, turns again and then flows from the second sub-channel 10cb into the first sub-channel 10ca along a second direction of the first direction, and finally continues to flow into the main storage cavity 10a along the second direction of the first direction.

[0119] In this way, it is beneficial to further shorten the total length of the main channel 10c and the additional channel 20b, and beneficial to make the outline of the atomizer 10 and the additional oil compartment 20 more compact.

[0120] In some embodiments, referring to Figure 14 and Figure 20 , the additional storage cavity 20a comprises a second protruding portion 20aa protruding from one end of the main storage cavity 10a along the first direction, the second protruding portion 20aa being in communication with the additional channel 20b.

[0121] It can be understood that the additional communication port 20c is located on the inner wall of the side of the second protruding portion 20aa close to the main storage cavity 10a along the second direction.

[0122] In some embodiments, in a projection plane perpendicular to the second direction, the projection of the main passage 10c and the projection of the additional passage 20b are both located within the projection range of the second protrusion 20aa, so as to reduce the size of the main passage 10c and the additional passage 20b and reduce the amount of aerosol generating substrate remaining in the main passage 10c.

[0123] In some embodiments provided with the main passage 10c and the additional passage 20b, the main passage 10c is located at one side of the main storage cavity 10a along the second direction, in the connected state, a part of the additional oil tank 20 is inserted into the main passage 10c, and the additional passage 20b is open at one side along the second direction to form an additional communication port 20c, and the other side is open for communication with the main storage cavity 10a.

[0124] The aerosol generating substrate in the additional storage cavity 20a first flows along the first direction of the first direction, and then flows along the second direction to enter the additional passage 20b. After flowing out of the additional passage 20b, part of the aerosol generating substrate flows along the second direction to a part of the main storage cavity 10a, and the other part flows along the second direction of the second direction to the other part of the main storage cavity 10a.

[0125] In this way, it is beneficial to reduce the overall outer size of the atomizer 10 and the additional oil tank 20 after the main storage cavity 10a and the additional storage cavity 20a are connected, and it is beneficial to make the structure of the aerosol generating device more compact.

[0126] In other embodiments provided with the main passage 10c and the additional passage 20b, referring to Figure 23 , the main passage 10c is located at one side of the main storage cavity 10a along the second direction, in the connected state, a part of the atomizer 10 is inserted into the additional passage 20b, and the main passage 10c is open at one side along the second direction to form a main communication port 10d, and the other side is open for communication with the additional storage cavity 20a.

[0127] A part of the atomizer 10 is inserted into the additional passage 20b from the opening of the end of the additional passage 20b away from the additional communication port 20c.

[0128] The aerosol generating substrate in the additional storage cavity 20a first flows along the first direction of the first direction, and then flows along the second direction to enter the additional passage 20b. After flowing out of the additional passage 20b, part of the aerosol generating substrate flows along the second direction to a part of the main storage cavity 10a, and the other part flows along the second direction of the second direction to the other part of the main storage cavity 10a.

[0129] In this way, it is beneficial to reduce the overall outer size of the atomizer 10 and the additional oil tank 20 after the main storage cavity 10a and the additional storage cavity 20a are connected, and it is beneficial to make the structure of the aerosol generating device more compact.

[0130] It can be understood that the part of the atomizer 10 and the inner wall of the additional channel 20b are sealed and fit with each other.

[0131] In some embodiments, referring to Figure 23 In the projection plane perpendicular to the second direction, the projection of the main channel 10c and the projection of the additional channel 20b are both located within the projection range of the main storage cavity 10a and within the projection range of the additional storage cavity 20a.

[0132] In some embodiments, the additional channel 20b extends linearly along the second direction, so that the part of the atomizer 10 is inserted into the additional channel 20b in a linear direction, simplifying the operation steps of the user.

[0133] In some embodiments, referring to Figure 4 , Figure 14 and Figure 23 The liquid storage member 12 covers at least part of the main communication port 10d.

[0134] In this way, it is beneficial for the aerosol generating substrate to be more quickly absorbed by the first liquid storage member 12 after flowing out of the main channel 10c, reducing the probability of the aerosol generating substrate flowing directly to the atomization core 111.

[0135] The specific way in which a part of the additional oil tank 20 can move relative to another part to switch between the communication state and the sealing state is not limited.

[0136] In some embodiments, referring to Figure 4 , Figures 8 to 10 , Figure 14 , Figures 18 to 20 The additional oil tank 20 includes a sealing movable block 22 and a shell assembly 21, the shell assembly 21 includes the additional channel 20b and the additional storage cavity 20a, the additional channel 20b communicates with the additional storage cavity 20a to form the additional communication port 20c and communicates with the outside of the shell assembly 21, the sealing movable block 22 is provided with a through adapter channel 22a, and the atomizer 10 can push the sealing movable block 22 to translate or rotate relative to the shell assembly 21 to switch the additional oil tank 20 between the communication state and the sealing state. In the sealing state, the sealing movable block 22 seals the opening provided in the additional channel 20b, and in the communication state, the adapter channel 22a communicates with the additional channel 20b.

[0137] The part of the atomizer 10 can be inserted into the adapter channel 22a through one end opening of the adapter channel 22a, so that the part of the atomizer 10 can abut against the inner wall of the adapter channel 22a. A force transmission path is formed by the abutment between the atomizer 10 and the sealing movable block 22, so that the sealing movable block 22 can move with the atomizer 10 and further move relative to the shell assembly 21.

[0138] Translation, refers to the sealing movable block 22 can be relative to the shell assembly 21 along a linear direction of movement.

[0139] Rotation, refers to the sealing movable block 22 can be relative to the shell assembly 21 with a linear rotation center.

[0140] In the sealed state, the sealing movable block 22 relative to the shell assembly 21 to the first position, so that the sealing movable block 22 cover additional channel 20b for the opening of the shell assembly 21 outside the communication, so that the aerosol generating substrate is difficult to leak from the additional channel 20b inside.

[0141] In the communication state, the sealing movable block 22 relative to the shell assembly 21 to the second position, located in the adapter channel 22a atomizer 10 part of the channel can be connected with the additional channel 20b, so that the additional storage cavity 20a inside the aerosol generating substrate through the adapter channel 22a into the atomizer 10.

[0142] Some embodiments, the sealing movable block 22 located outside the shell assembly 21.

[0143] Some embodiments, a part of the atomizer 10 can be inserted into the adapter channel 22a and abut with the inner wall of the adapter channel 22a to push the sealing movable block 22 relative to the shell assembly 21 translation or rotation.

[0144] It can be understood that, in the additional oil bunker 20 and atomizer 10 separated state, the additional oil bunker 20 in the sealed state.

[0145] It can be understood that, the atomizer 10 can not enter the additional channel 20b, to avoid the atomizer 10 and the inner wall of the additional channel 20b abutment so that the sealing movable block 22 can not be relative to the shell assembly movement.

[0146] Some embodiments, refer to Figures 13 to 20 , a part of the atomizer 10 can be inserted into the adapter channel 22a and can push the sealing movable block 22 relative to the shell assembly 21 translation along the first direction.

[0147] Some embodiments, refer to Figures 8 to 10 , Figures 18 to 20The additional oil tank 20 further comprises a cover 23, which is arranged on the outer surface of the shell assembly 21 and forms a limiting space with the shell assembly 21, the additional channel 20b is in communication with the limiting space, and the sealing movable block 22 is located in the limiting space and is in stop cooperation with the cover 23 and the shell assembly 21 at two ends along the penetrating direction of the adapter channel 22a. The cover 23 is provided with an avoiding channel 23a penetrating along the penetrating direction of the adapter channel 22a, the avoiding channel 23a is in communication with the adapter channel 22a and the outside of the additional oil tank 20, and a part of the atomizer 10 can penetrate through the avoiding channel 23a and be inserted into the adapter channel 22a.

[0148] The sealing movable block 22 is located in the limiting space and is clamped between the cover 23 and the shell assembly 21, so as to limit the movement range of the sealing movable block 22 and reduce the probability of falling off of the sealing movable block 22 from the shell assembly 21.

[0149] After a part of the atomizer 10 is inserted into the adapter channel 22a, the atomizer 10 can move in the avoiding channel 23a. The inner wall of the avoiding channel 23a can guide and constrain the movement of the atomizer 10, so that the sealing movable block 22 can move along the predetermined movement route.

[0150] In some embodiments, referring to Figures 4 to 8 A part of the atomizer 10 can be inserted into the adapter channel 22a and can push the sealing movable block 22 to rotate relative to the shell assembly 21.

[0151] In some embodiments, referring to Figure 8 The rotation axis 22b of the sealing movable block 22 is in the first direction, so that the rotation of the sealing movable block 22 does not interfere with the cooperation between the atomizer 10 and the sealing movable block 22.

[0152] In some embodiments, referring to Figures 8 to 10 The additional oil tank 20 is provided with a placement hole 21a, which is open at least on one side along the first direction, and at least part of the atomizer 10 is located in the placement hole 21a.

[0153] It can be understood that the additional storage cavity 20a and the additional channel 20b are isolated from each other by the placement hole 21a.

[0154] The inner wall of the placement hole 21a can limit the part of the atomizer 10 entering the placement hole 21a.

[0155] The placement hole 21a enables the shell assembly 21 to protect at least part of the atomizer 10, thereby reducing the probability of damage of the atomizer 10 due to bumping and other factors during use of the aerosol generating device.

[0156] In some embodiments, referring toFigures 23 to 25 The additional oil tank 20 comprises a sealing member 24 and a housing assembly 21, the housing assembly 21 comprises an insertion channel 21e and an additional storage cavity 20a, the insertion channel 21e communicates with the additional storage cavity 20a to form an additional communication port 20c and communicates with the outside of the housing assembly 21, the sealing member 24 comprises a blocking part 241 and an elastic reset part, the blocking part 241 is arranged in the additional storage cavity 20a and blocks the insertion channel 21e, part of the elastic reset part is fixed to the housing assembly 21, the insertion channel 21e is used for inserting the atomizer 10 into the inside to push the blocking part 241 to move away from the insertion channel 21e, in the communication state, the blocking part 241 moves away from the insertion channel 21e, the elastic reset part is elastically deformed to make the blocking part 241 generate a movement trend towards the insertion channel 21e to block the insertion channel 21e.

[0157] The blocking part 241 is used for covering the additional communication port 20c.

[0158] In the state that the blocking part 241 blocks the insertion hole, the insertion hole is not communicated with the additional storage cavity 20a, and the aerosol generating substrate in the additional storage cavity 20a cannot flow out of the additional oil tank 20 through the insertion hole.

[0159] The atomizer 10 is at least partially inserted into the additional channel 20b until abutting against the blocking part 241, and then pushes the blocking part 241 to move, so that the blocking part 241 moves away from the additional channel 20b to enable communication with the additional storage cavity 20a, and the aerosol generating substrate in the additional storage cavity 20a can enter.

[0160] The elastic reset part can be elastically deformed under external force to stretch and contract with the movement of the blocking part 241.

[0161] It can be understood that the atomizer 10 pushes the blocking part 241 to relatively move until the blocking part 241 is out of contact to realize the unblocking effect of the blocking part 241 on the additional channel 20b. During the movement of the blocking part 241, the elastic reset part is elastically deformed to enable the part connected with the blocking part 241 to relatively move with respect to the relatively fixed part, and then the elastic reset part exerts an elastic force on the blocking part 241.

[0162] In the state of abutting against the blocking part 241, although the blocking part 241 has a movement tendency of moving towards the additional channel 20b due to the elastic force applied by the elastic reset part, the abutting force on the blocking part 241 is balanced with the elastic force of the elastic reset part on the blocking part 241, so that the position of the blocking part 241 is relatively fixed, and the aerosol generating substrate in the additional storage cavity 20a can flow into the middle more stably; in the state of the additional oil compartment 20 being separated for replacement, the blocking part 241 is separated from the additional channel 20b, so that the blocking part 241 is no longer subjected to the abutting force, and under the action of the elastic force of the elastic reset part on the blocking part 241, the sealing part 24 moves towards the additional channel 20b until the blocking part 241 abuts against and re-blocks the additional channel 20b.

[0163] In this way, by using the elastic force of the elastic reset part, the position of the blocking part 241 in the additional storage cavity 20a can be maintained in the state that the atomizer 10 is inserted into the additional channel 20b, and the abnormal noise caused by the shaking of the blocking part 241 in the additional storage cavity 20a is reduced; on the other hand, the blocking part 241 can re-block the additional channel 20b after the atomizer 10 is pulled out of the additional channel 20b, and the probability of leakage of the aerosol generating substrate in the additional storage cavity 20a after the additional oil compartment 20 is removed from the aerosol generating device is reduced.

[0164] In some embodiments, referring to Figure 5 , Figure 15 and Figure 26 , one of the atomizer 10 and the additional oil compartment 20 is provided with a containing groove 10f, which is open along the second direction towards the side of the other one so that a part of the other one can be embedded in the containing groove 10f. In this way, the inner wall of the containing groove 10f can play a certain protection and limiting role.

[0165] In some embodiments, referring to Figure 5 , Figure 15 and Figure 26 , the outer surface of the atomizer 10 is provided with a plug-in column 112, at least part of the plug-in column 112 is used for being inserted into the additional oil compartment 20, and at least part of the main channel 10c is located in the plug-in column 112, so as to maintain the communication between the additional storage cavity 20a and the main storage cavity 10a by the stop cooperation between the plug-in column 112 and the additional oil compartment 20.

[0166] It can be understood that the plug-in column 112 is used for being inserted into the adapter channel 22a or the plug-in channel 21e.

[0167] In some embodiments, referring to Figure 1 , Figure 11 and Figure 21The aerosol-generating device further comprises a power supply assembly 30 for electrically connecting with the atomizer 10 to provide electric energy to the atomizer 10, and any two of the power supply assembly 30, the atomizer 10 and the additional oil tank 20 are detachably connected, so as to facilitate disassembly of any one of them and facilitate mutual constraint of the three to improve the connection stability.
