[0005] The aerosol-generating device includes an atomizer and an additional oil tank. An atomization core in the atomizer can absorb aerosol-generating substrate and convert the aerosol-generating substrate into aerosol. After the aerosol-generating substrate in the atomizer is consumed to a certain extent, the aerosol-generating substrate stored in the additional oil tank enters the atomizer through the outlet of the additional oil tank to play a replenishing role, thereby prolonging the service life of the aerosol-generating device.

[0006] In the related art, because of the existence of the additional oil tank, the overall size of the aerosol-generating device is increased, and the flow path of the aerosol can be too long, which can easily increase the probability of condensation of the aerosol during flow, reduce the amount of discharged aerosol, and adversely affect the user's inhalation experience.

DETAILED DESCRIPTION

[0070] 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 the explanation and description of the purpose of the embodiments of the present application, and should not be regarded as improper limitation of the embodiments of the present application.

[0071] In the description of the embodiments of the present application, the "first direction" orientation or positional relationship is based on the orientation or positional relationship shown by the arrow X in the drawing; the "second direction" orientation or positional relationship is based on the orientation or positional relationship shown by the arrow Y in the drawing.

[0072] It should be understood that these orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the embodiments of the present application.

[0073] The embodiments of the present application provide an aerosol generating device for forming an aerosol by heating or the like from an aerosol generating substrate for a user to smoke.

[0074] Referring to Figures 1 to 4 , Figures 15 to 17 , Figure 23 , Figure 25 , Figure 26 and Figure 29 , the aerosol generating device includes an atomizer 10 and an additional oil storehouse 20.

[0075] The atomizer 10 comprises an air outlet passage 10b and a main storage cavity 10a, the outlet of the air outlet passage 10b communicates with the outside of the aerosol generating device, and the air outlet passage 10b extends along a first direction.

[0076] The additional oil tank 20 is located at least partially on at least one side of the atomizer 10 along a second direction, the first direction intersects the second direction, and the additional oil tank 20 comprises a sealing movable block 22 and a housing assembly 21, the housing assembly 21 comprises a fluid passage 20b and an additional storage cavity 20a, and the fluid passage 20b communicates the additional storage cavity 20a with the outside of the housing assembly 21.

[0077] The atomizer 10 and the sealing movable block 22 are capable of moving together relative to the housing assembly 21 to switch the additional oil tank 20 between a communication state and a sealing state.

[0078] In the sealing state, the sealing movable block 22 closes the fluid passage 20b, and in the communication state, the fluid passage 20b is opened to communicate the main storage cavity 10a with the additional storage cavity 20a.

[0079] The air outlet passage 10b is used to discharge the aerosol formed by the atomizer 10. During the user inhaling the aerosol, the aerosol enters the user's oral cavity through the outlet of the air outlet passage 10b.

[0080] The outlet of the air outlet passage 10b is oriented in the first direction, and during the user inhaling the aerosol, the first direction is generally along the vertical direction, and the outlet of the air outlet passage 10b is oriented upward.

[0081] The main storage cavity 10a is capable of storing a certain amount of aerosol generating substrate, and the atomizer 10 converts the aerosol generating substrate in the main storage cavity 10a into aerosol.

[0082] The additional storage cavity 20a is capable of storing a certain amount of aerosol generating substrate, and in the state that the main storage cavity 10a communicates with the additional storage cavity 20a, the aerosol generating substrate in the additional storage cavity 20a can enter the main storage cavity 10a to supplement the amount of aerosol generating substrate in the main storage cavity 10a, so that the atomizer 10 can supply aerosol for a longer time.

[0083] It can be understood that the aerosol generating substrate is a fluid medium, so that the aerosol generating substrate can flow between the main storage cavity 10a and the additional storage cavity 20a.

[0084] At least part of the additional oil tank 20 is located on at least one side of the atomizer 10 along the second direction, which is beneficial to reduce the size of the aerosol generating device along the first direction.

[0085] The atomizer 10 and the sealing movable block 22 are in contact, so that the atomizer 10 and the sealing movable block 22 form a force transmission path.

[0086] The user, after exerting a force on at least one of the atomizer 10 or the additional tank 20, the atomizer 10 and the sealing movable block 22 can synchronously move relative to the housing assembly 21, so that the sealing movable block 22 can move relative to the housing assembly 21 to at least two different relative positions respectively. When the two are in one of the relative positions, the additional tank 20 is in a communication state, the fluid channel 20b is open and in communication with the main storage cavity 10a, so that the main storage cavity 10a is in communication with the additional storage cavity 20a; when the two are in the other relative position, the sealing movable block 22 closes the fluid channel 20b, and the main storage cavity 10a is not in communication with the additional storage cavity 20a, so that the aerosol generating substrate can no longer flow from the additional storage cavity 20a into the main storage cavity 10a.

[0087] In the aerosol generating device in the embodiments of the present application, at least part of the additional tank 20 is located on one side of the atomizer 10 along the second direction, and the length of the flow path of the aerosol is determined by the length of the gas outlet channel 10b of the atomizer 10, which reduces the influence of the size of the additional tank 20, is beneficial to shorten the length of the flow path of the gas flow in the gas outlet channel 10b, and is beneficial to reduce the probability of condensation of the aerosol in the gas outlet channel 10b; moreover, since the additional tank 20 and the atomizer 10 need to cooperate with each other to realize the movement of one part relative to the other part, so as to realize the communication or disconnection of the main storage cavity 10a and the additional storage cavity 20a, it is beneficial for the user to use the additional tank 20 of a specific shape cooperating with the atomizer 10, so that the specific length of the flow path of the atomizer 10 is used in cooperation with the specific aerosol generating substrate, so as to obtain better user experience, and it is also beneficial to reduce the probability of leakage of the aerosol generating substrate due to accidental opening of the main storage cavity 10a or the additional storage cavity 20a alone during separate packaging and transportation of the additional tank 20 or the atomizer 10 respectively; in addition, by additionally providing the additional storage cavity 20a, it is beneficial to reduce the volume of the main storage cavity 10a, and is beneficial to further reduce the probability of leakage of the aerosol generating substrate during separate transportation of the atomizer 10, and is beneficial to maintain the freshness of the aerosol generating substrate during use of the aerosol generating device.

[0088] In some embodiments, the first direction is perpendicular to the second direction.

[0089] In some embodiments, the atomizer 10 and the additional tank 20 are detachably connected, so as to replace the additional tank 20.

[0090] In some embodiments, reference can be made to Figure 4 , Figure 5 , Figure 11 , Figure 13 and Figure 37The atomizer 10 further comprises a main passage 10c extending along the second direction and communicating the main storage cavity 10a with the outside of the atomizer 10. The atomizer 10 is provided with a plug-in post 112 extending along the second direction, which is configured to be inserted into the additional oil tank 20 and stopper-fitted with the additional oil tank 20 perpendicularly to the second direction, so that the relative position between the atomizer 10 and the additional oil tank 20 is fixed.

[0091] In some embodiments, referring to Figure 3 , Figure 4 , Figure 17 , Figure 18 , Figure 21 and Figure 22 The atomizer 10 comprises an atomization assembly 11 and a liquid storage member 12. The atomization assembly 11 comprises a main storage cavity 10a, an air outlet passage 10b and a main passage 10c. The liquid storage member 12 is arranged in the main storage cavity 10a and 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.

[0092] The liquid storage member 12 is in fluid communication with the atomization assembly 11, so that the aerosol generating substrate can flow from one to the other. The specific way of realizing the fluid communication between the two is not limited, for example, the two are in direct contact, or a passage is arranged between the two to enable the fluid to contact the two through the passage.

[0093] After the liquid storage member 12 contacts 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.

[0094] In some embodiments, referring to Figure 4 and Figure 18 The liquid storage member 12 covers at least part of the main communication port 10d.

[0095] In this way, it is beneficial for the aerosol generating substrate flowing out of the main passage 10c to be more quickly absorbed by the first liquid storage member 12, reducing the probability of the aerosol generating substrate flowing directly to the atomization core 111.

[0096] The adapter passage 22a extends along the first direction to enable the atomizer 10 to be inserted thereinto along the first direction. The adapter passage 22a can be a blind hole extending along the first direction, or a through hole extending along the first direction.

[0097] In some embodiments, referring to Figures 8 to 10 , Figure 12 , Figure 14 , Figure 23 ,Figure 25 、 Figure 26 and Figure 29 The sealing movable block 22 is located outside the housing assembly 21 and is provided with an adapter passage 22a, a part of the atomizer 10 can be inserted into the adapter passage 22a and can push the sealing movable block 22 to translate or rotate relative to the housing assembly 21, so as to switch the additional oil tank 20 between the communication state and the sealing state.

[0098] A part of the atomizer 10 can be inserted into the adapter passage 22a through an end opening of the adapter passage 22a, so that the part of the atomizer 10 can abut against the inner wall of the adapter passage 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 then move relative to the housing assembly 21.

[0099] Translation refers to that the sealing movable block 22 can move along a certain linear direction relative to the housing assembly 21.

[0100] Rotation refers to that the sealing movable block 22 can rotate relative to the housing assembly 21 with a certain linear direction as the rotation center.

[0101] In the sealing state, the sealing movable block 22 moves to a first position relative to the housing assembly 21, so that the sealing movable block 22 covers the opening of the fluid passage 20b for communication with the outside of the housing assembly 21, so that the aerosol generating substrate is difficult to leak from the fluid passage 20b.

[0102] In the communication state, the sealing movable block 22 moves to a second position relative to the housing assembly 21, and a part of the atomizer 10 can communicate with the fluid passage 20b, so that the aerosol generating substrate in the additional storage cavity 20a enters the atomizer 10 through the adapter passage 22a.

[0103] The inner wall of the adapter passage 22a plays a role of restraint and limiting on the part of the atomizer 10 inserted into the adapter passage 22a, which reduces the probability of disengagement between the sealing movable block 22 and the atomizer 10 during the movement of the sealing movable block 22 together with the atomizer 10.

[0104] It can be understood that in the state that the additional oil tank 20 is separated from the atomizer 10, the additional oil tank 20 is in the sealing state.

[0105] In some embodiments, referring to Figures 8 to 10 、 Figure 12 、 Figure 14 、 Figure 23 、 Figure 25 、 Figure 26 and Figure 29The switching channel 22a extends through the sealing movable block 22 along the first direction. In the communication state, the fluid channel 20b communicates with the switching channel 22a, so that the main storage cavity 10a communicates with the additional storage cavity 20a.

[0106] The switching channel 22a extends along the first direction so that the atomizer is inserted along the first direction. The switching channel 22a is open at one end along the first direction for the insertion of the atomizer 10, and is open at the other end for communication with the fluid channel 20b.

[0107] The switching channel 22a also functions to communicate the main storage cavity 10a with the additional storage cavity 20a, so as to facilitate the compact structure of the atomizer 10 and the additional oil tank 20.

[0108] It can be understood that the atomizer 10 cannot enter the fluid channel 20b, so as to avoid the abutment between the atomizer 10 and the inner wall of the fluid channel 20b, which makes the sealing movable block 22 unable to move relative to the assembly of the shell.

[0109] In some embodiments, the atomizer 10 can abut the additional oil tank 20 along the extension direction of the switching channel 22a, so as to limit the depth of the atomizer 10 inserted into the part of the switching channel 22a, and reduce the probability of the atomizer 10 entering the fluid channel 20b.

[0110] In some embodiments, the outer surface of the shell assembly 21 is provided with a guide groove, and at least part of the sealing movable block 22 is located in the guide groove, so that the inner wall of the guide groove functions to constrain and guide the movement of the sealing movable block 22, and facilitates the movement of the sealing movable block 22 along the predetermined movement route.

[0111] In some embodiments, in the communication state, the sealing movable block 22 is clamped between the part of the atomizer 10 and the shell assembly 21, so that the part of the atomizer 10 and the shell assembly 21 can shield the sealing movable block 22, and reduce the probability that foreign matter in the process of using the aerosol device causes the sealing movable block 22 and the shell assembly 21 to be difficult to move relative to each other.

[0112] In some embodiments, referring to Figure 17 and Figure 18 , the part of the atomizer 10 is located on one side of the shell assembly 21 along the first direction, the sealing movable block 22 is located on the side of the shell assembly 21 along the first direction close to the atomizer 10, and the switching channel 22a extends along the first direction.

[0113] In this way, the part of the atomizer 10 can be inserted into the switching channel 22a along the first direction. This facilitates the reduction of the size of the overall outer contour of the atomizer 10 and the shell assembly 21 along the second direction in the communication state.

[0114] In some embodiments, referring to Figure 16and Figure 17 The housing assembly 21 is located on the side of the atomizer 10 away from the outlet of the air outlet passage 10b in the first direction.

[0115] In some embodiments, referring to Figure 26 The sealing movable block 22 translates relative to the housing assembly 21 in the second direction. The operation mode of translation is simple, which facilitates the operation of the user and reduces the difficulty of use of the user.

[0116] In some embodiments, referring to Figure 19 、 Figure 23 、 Figure 25 、 Figure 29 and Figure 31 The sealing movable block 22 rotates relative to the housing assembly 21, and the first rotation axis 22b formed by the rotation extends in the first direction. The operation mode of rotation is simple, which is conducive to reducing the active space required by the housing assembly 21 during movement and reducing the probability of interference between the housing assembly 21 and other devices in the aerosol generating device during movement.

[0117] It can be understood that the atomizer 10 needs an atomization core 111 for converting the aerosol generating substrate into aerosol and directly contacts the user's mouth, and the hygiene requirement is higher. Therefore, the manufacturing cost of the atomizer 10 is higher than that of the additional oil tank 20.

[0118] In some embodiments, referring to Figure 19 and Figure 23 The housing assembly 21 further comprises a placement hole 21a, the placement hole 21a is open on at least one side in the first direction to form a first placement opening 21b, and at least part of the atomizer 10 can be inserted into the placement hole 21a through the first placement opening 21b.

[0119] It can be understood that the additional storage cavity 20a and the fluid passage 20b are both isolated from the placement hole 21a.

[0120] The inner wall of the placement hole 21a can limit the part of the atomizer 10 entering the placement hole 21a.

[0121] The placement hole 21a allows the housing assembly 21 to protect at least part of the atomizer 10, reducing the probability of damage to the atomizer 10 due to bumping and other factors during use of the aerosol generating device.

[0122] In some embodiments, referring to Figure 23 The placement hole 21a extends through the housing assembly 21 in the first direction, so as to increase the size of the placement hole 21a in the first direction, which is conducive to increasing the volume of the part of the atomizer 10 located in the placement hole 21a.

[0123] In some embodiments, referring toFigure 25 、 Figure 26 and Figure 29 The housing assembly 21 further comprises a placement slot 21c which is open along at least one side in the first direction to form a first placement opening 21b and open along one side in the second direction to form a second placement opening 21d, and at least a portion of the atomizer 10 is capable of being inserted into the placement slot 21c through at least one of the first placement opening 21b and the second placement opening 21d.

[0124] It can be understood that the additional storage cavity 20a and the fluid channel 20b are each isolated from the placement slot 21c.

[0125] The inner wall of the placement hole 21a is capable of limiting the portion of the atomizer 10 entering the placement slot 21c.

[0126] By means of the placement slot 21c, the housing assembly 21 is capable of protecting at least a portion of the atomizer 10, and reducing the probability of damage to the atomizer 10 due to bumping and other factors during use of the aerosol generating device.

[0127] In some embodiments, at least a portion of the atomizer 10 is capable of being inserted into the placement slot 21c through the open position of the placement slot 21c in the first direction. In this way, it is beneficial to improve the flexibility of the cooperation between the atomizer 10 and the additional oil store 20.

[0128] In some embodiments provided with the placement slot 21c, referring to Figure 26 The sealing movable block 22 translates relative to the housing assembly 21 in the second direction, and in this way, by means of the placement slot 21c, the second placement opening 21d is in communication with the outside of the housing assembly 21, which is beneficial to reduce the outer contour size of the housing assembly 21 and make the structure of the aerosol generating device more compact, while meeting the requirement of the translation stroke of the housing assembly 21 relative to the atomizer 10.

[0129] The specific number of the additional oil stores 20 is not limited. For example, referring to Figure 19 and Figure 24 the number of the additional oil stores 20 is one; for example, referring to Figure 27 and Figure 30 the number of the additional oil stores 20 is multiple.

[0130] In some embodiments in which the number of the additional oil stores 20 is multiple, referring to Figure 28 and Figure 31 the multiple additional oil stores 20 surround to form a placement space 20d for accommodating at least a portion of the atomizer 10.

[0131] It can be understood that in some embodiments, referring to Figure 28 and Figure 31 the multiple placement slots 21c form the placement space 20d.

[0132] In some embodiments including the placement space 20d, referring to Figure 31 , a plurality of additional oil tanks 20 surround the formed surrounding axis 20e and extend along the first direction, the placement space 20d is open along at least one side of the first direction, and at least part of the atomizer 10 is located in the placement space 20d.

[0133] Along the circumference of the surrounding axis 20e, two adjacent additional oil tanks 20 abut each other. In this way, it is beneficial to limit the relative position between the additional oil tanks 20, and it is beneficial to improve the stability of the relative position between the additional oil tanks 20.

[0134] The specific number of the plurality of additional oil tanks 20 is not limited, for example, referring to Figure 28 , the number of additional oil tanks 20 is two; for another example, referring to Figure 31 , the number of additional oil tanks 20 is four.

[0135] It can be understood that, in the process of the user operating the atomizer 10 to rotate relative to the shell assembly 21, it is necessary to enable the user to perceive that the additional oil tank 20 has switched to the sealed state, so as to reduce the risk of leakage of the aerosol generating substrate caused by user misoperation.

[0136] Specifically, referring to Figure 19 , Figure 20 , Figure 23 and Figure 24 , one of the additional oil tank 20 and the atomizer 10 is provided with a sliding block 213, and the other is provided with a sliding groove 11d and a limiting groove 11e, the sliding groove 11d extends along the extension direction of the adapter channel 22a, the sliding groove 11d is open at one end along the extension direction of the adapter channel 22a to form an entrance 11g and the other end is in communication with the limiting groove 11e, the limiting groove 11e extends along the rotation direction of the sealing movable block 22 and one side thereof along the rotation direction of the sealing movable block 22 is provided with a limiting surface 11f, the sliding block 213 can enter and exit the sliding groove 11d through the entrance 11g and slide in the sliding groove 11d and the limiting groove 11e, and in the communication state, the sliding block 213 abuts against the limiting surface 11f along the rotation direction of the sealing movable block 22.

[0137] In the process of inserting the atomizer 10 into the adapter channel 22a, the sliding block 213 is simultaneously inserted into the sliding groove 11d through the entrance 11g and moves along the extension direction of the adapter channel 22a until the atomizer 10 is inserted into the adapter channel 22a to a depth that meets the preset requirement, and then the atomizer 10 and the sealing movable block 22 are rotated together so that the sliding block 213 is simultaneously rotated relative to the inner wall of the limiting groove 11e until the sliding block 213 abuts against the limiting surface 11f on one side of the inner wall of the sealing movable block 22 in the rotation direction, so that the atomizer 10 and the sealing movable block 22 cannot rotate relative to the shell assembly 21. In this way, the user can perceive through the force feedback that the sealing movable block 22 is in the connected state and can normally use the aerosol generating device.

[0138] It can be understood that the rotation direction of the sliding block 213 relative to the inner wall of the limiting groove 11e has two directions. In some embodiments, at least one of the atomizer 10 and the additional oil store 20 is provided with an indication pattern of the rotation direction, so that the user can know the preset direction of the rotation direction of the sliding block 213 relative to the inner wall of the limiting groove 11e according to the indication pattern, thereby improving the user experience.

[0139] The number of the sliding groove 11d and the limiting groove 11e is the same as the number of the sliding block 213, which can be one or multiple.

[0140] In some embodiments, referring to Figure 23 , the sliding groove 11d and the limiting groove 11e or the sliding block 213 are arranged on the inner wall of the placement hole 21a or the placement groove 21c, so as to reduce the probability that foreign matters from the outside enter the sliding groove 11d and the limiting groove 11e and cause the atomizer 10 and the sealing movable block 22 to be unable to rotate relative to each other.

[0141] In some embodiments, the sliding block 213 is provided with a clamping groove, and the limiting groove 11e is provided with a positioning protrusion, the limiting surface 11f is formed on one side surface of the positioning protrusion in the rotation direction of the sealing movable block 22, and the sliding block 213 can be elastically deformed so that the positioning protrusion can be embedded in the clamping groove. In the connected state, the positioning protrusion is embedded in the clamping groove, and the limiting surface 11f abuts against the inner wall of the clamping groove in the rotation direction of the sealing movable block 22.

[0142] In this way, it is beneficial to keep the position of the atomizer 10 and the shell assembly 21 stable in the rotation direction of the sealing movable block 22.

[0143] In some embodiments, referring to Figure 3 and Figure 4 , the sealing movable block 22 is located on one side of the shell assembly 21 close to the atomizer 10 in the second direction, and the adapter channel 22a penetrates in the second direction.

[0144] In this way, a portion of the atomizer 10 can be inserted into the adapter channel 22a in the second direction.

[0145] In some embodiments, referring to Figure 5 and Figure 12 the sealing movable block 22 is translated relative to the housing assembly 21 in a direction perpendicular to the second direction. The operation mode of translation is simple, which is convenient for the user to operate and reduces the difficulty of use for the user.

[0146] Referring to Figure 5 the direction perpendicular to the second direction can be the first direction; referring to Figure 12 it can also be a direction perpendicular to the first direction and the second direction.

[0147] In some embodiments, referring to Figure 13 and Figure 14 the sealing movable block 22 is rotated relative to the housing assembly 21 and the second rotation axis 22c formed thereby extends in the second direction. The operation mode of rotation is simple, which is conducive to reducing the active space required by the housing assembly 21 during movement and reducing the probability of interference with other devices in the aerosol generating device during movement of the housing assembly 21.

[0148] In some embodiments, referring to Figure 18 the fluid channel 20b and the additional storage cavity 20a form an additional communication port 20c at a position of communication therebetween, and the additional communication port 20c is located on one side of the additional storage cavity 20a in the first direction.

[0149] That is, the perpendicular 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.

[0150] The perpendicular bisector between the two points farthest apart in the first direction of the additional storage cavity 20a refers to the perpendicular bisector of the connecting line formed by the two points farthest apart in the first direction of the additional storage cavity 20a.

[0151] As the aerosol in the additional storage cavity 20a is consumed, the aerosol generating device in the additional storage cavity 20a can deposit on the side of the additional storage cavity 20a close to the ground under the action of gravity, with the outlet of the air outlet channel 10b facing upward or downward.

[0152] In this way, it is beneficial to adjust the posture of the aerosol generating device so that the additional communication port 20c is located on the side of the additional storage cavity 20a closer to the ground, so that the aerosol generating substrate enters the fluid channel 20b, and the utilization rate of the aerosol generating substrate in the additional storage cavity 20a is improved.

[0153] In the embodiment where the additional storage cavity 20a is located on the side of the additional storage cavity 20a away from the outlet of the air outlet passage 10b along the first direction, the additional communication port 20c is located on the side of the additional storage cavity 20a closer to the ground during the user's process of smoking the aerosol. In the embodiment where the additional storage cavity 20a is located on the side of the additional storage cavity 20a close to the outlet of the air outlet passage 10b along the first direction, the user needs to supplement the main storage cavity 10a during the use process, and the aerosol generating device can be inverted so that the outlet of the air outlet passage 10b faces downward and the additional communication port 20c is located on the side of the additional storage cavity 20a closer to the ground.

[0154] In some embodiments, the number of additional oil tanks 20 is at least two, and the two additional oil tanks 20 are respectively located on one side of the atomizer 10 along the second direction.

[0155] In this way, the two additional oil tanks 20 are beneficially away from each other, reducing the interference of the other additional oil tank 20 with the user's operation during the disassembly and assembly of one of the additional oil tanks 20, and improving the operation efficiency.

[0156] In some embodiments, referring to Figure 3 , Figure 19 , Figure 27 and Figures 8 to 10 , the end surface of the atomizer 10 on the side away from the outlet of the air outlet passage 10b along the first direction is a first end surface 10e, the end surface of the additional oil tank 20 on the side away from the outlet of the air outlet passage 10b along the first direction is a second end surface 20f, and the first end surface 10e and the second end surface 20f are flush with each other in the communication state.

[0157] The first end surface 10e and the second end surface 20f are both flat surfaces.

[0158] In this way, the first end surface 10e and the second end surface 20f are beneficially used as the surface on which the aerosol generating device is placed, the outlet of the air outlet passage 10b faces upward, and the risk of condensate flowing out of the air outlet passage 10b is reduced.

[0159] In some embodiments, the first end surface 10e and the second end surface 20f are both perpendicular to the first direction, and the first end surface 10e and the second end surface 20f are beneficially used as the surface on which the aerosol generating device is placed, and the air outlet passage 10b extends along the vertical direction.

[0160] In some embodiments, referring to Figure 12 , Figure 14 , Figure 23 , Figure 25 , Figure 26 , Figure 29 andFigure 5 The 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 20g together with the shell assembly 21, and the sealing movable block 22 is arranged in the limiting space 20g. The two ends of the sealing movable block 22 along the extension direction of the adapter channel 22a are respectively in abutting stop cooperation with the cover 23 and the shell assembly 21. The cover 23 is provided with an avoiding channel 23a penetrating along the extension 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 pass through the avoiding channel 23a and be inserted into the adapter channel 22a.

[0161] The sealing movable block 22 is arranged in the limiting space 20g and clamped between the cover 23 and the shell assembly 21, so as to limit the activity range of the sealing movable block 22 and reduce the probability of separation between the sealing movable block 22 and the shell assembly 21.

[0162] 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.

[0163] It can be understood that the extension direction of the avoiding channel 23a is adapted to the predetermined movement route of the sealing movable block 22. For example, the sealing movable block 22 is in translational movement, and the avoiding channel 23a extends along a straight line direction; for another example, the sealing movable block 22 is in rotational movement, and the avoiding channel 23a extends along an arc direction.

[0164] In some embodiments, the cover 23 and the shell assembly 21 are detachably connected.

[0165] It can be understood that in the communication state, the tendency of the atomizer 10 to separate from the adapter channel 22a needs to be inhibited.

[0166] In some embodiments, referring to Figure 11 and Figure 5The limiting protrusion 211 is provided on one of the side of the atomizer 10 facing the additional oil tank 20 and the side of the additional oil tank 20 facing the atomizer 10, and the other side is provided with a stop space 11a, a plug hole 11b and a limiting hole 11c. The limiting protrusion 211 is provided with a stop block 2111 on the side perpendicular to the extension direction of the adapter channel 22a. The plug hole 11b and the limiting hole 11c are both in communication with the stop space 11a and the outside along the extension direction of the adapter channel 22a. The limiting protrusion 211 can pass through the limiting hole 11c along the extension direction of the adapter channel 22a so that the stop block 2111 is located in the stop space 11a. The plug hole 11b and the limiting hole 11c are in communication along the movement direction of the sealing movable block 22 relative to the housing assembly 21 so that the limiting protrusion 211 can pass between the plug hole 11b and the limiting hole 11c. In the sealing state, the stop block 2111 is in abutment with the inner wall of the stop space 11a along the extension direction of the adapter channel 22a.

[0167] During the process of inserting the atomizer 10 into the adapter channel 22a, at least part of the limiting protrusion 211 and the stop block 2111 pass through the plug hole 11b into the stop space 11a. In this state, in the projection plane perpendicular to the extension direction of the adapter channel 22a, the projection of the limiting protrusion 211 and the projection of the stop block 2111 are both located within the projection range of the plug hole 11b. During the process of moving the sealing movable block 22 driven by the atomizer 10, the limiting protrusion 211 enters the limiting hole 11c through the position where the plug hole 11b is in communication with the limiting hole 11c. In this state, in the projection plane perpendicular to the extension direction of the adapter channel 22a, at least part of the projection of the stop block 2111 is located outside the projection range of the limiting hole 11c, so that the stop block 2111 can abut with the inner wall of the stop space 11a, thereby making it difficult to separate from the stop space 11a through the limiting hole 11c, and further making it difficult for the atomizer 10 to separate from the adapter channel 22a.

[0168] In this way, in the communication state, the additional storage cavity 20a can stably provide aerosol generating substrate into the main storage cavity 10a, which is conducive to maintaining the sealing between the atomizer 10 and the inner wall of the adapter channel 22a, reducing the risk of leakage of aerosol generating substrate in the additional storage cavity 20a, and improving user experience.

[0169] In some embodiments including the cover 23, referring to Figure 12 , Figure 14 and Figure 13 , the cover 23 is provided with a plug hole 11b and a limiting hole 11c, the plug hole 11b and the limiting hole 11c pass through the cover 23, and at least part of the limiting space 20g forms the stop space 11a. In this way, the space utilization rate in the aerosol generating device is improved by utilizing the existing structure formed by the cover 23 and the housing assembly 21, and the structure of the aerosol generating device is more compact.

[0170] In some embodiments including the cover 23, referring to Figure 14 and Figures 5 to 7 , the housing assembly 21 is provided with a rotating shaft 212 protruding from the outer surface of the housing assembly 21 along the extension direction of the rotating channel 22a, the sealing movable block 22 is provided with a first rotating through hole penetrating along the extension direction of the rotating channel 22a, the cover 23 is provided with a second rotating through hole penetrating along the extension direction of the rotating channel 22a, the rotating shaft 212 is arranged in the first rotating through hole and the second rotating through hole and protrudes from the outside of the cover 23, and the outer surface of the atomizer 10 is provided with a rotating hole 10h which is open along the extension direction of the rotating channel 22a, and a part of the rotating shaft 212 can be embedded in the rotating hole 10h.

[0171] In this way, the central axis of the rotating shaft 212 forms the second rotating axis 22c of the atomizer 10 and the sealing movable block 22, and through the rotating hole 10h and the first rotating through hole, the atomizer 10 and the sealing movable block 22 are respectively limited in the direction perpendicular to the rotating axis.

[0172] In some embodiments, referring to Figures 5 to 7 , the atomizer 10 and the sealing movable block 22 can be translated relative to the housing assembly 21 in the direction perpendicular to the second direction, and one of the atomizer 10 and the additional oil tank 20 is provided with a containing groove 10f which is open to the side of the other in the second direction so that a part of the other can be embedded in the containing groove 10f and stop cooperating with the inner wall of the containing groove 10f at least in the direction perpendicular to the second direction.

[0173] In this way, the inner wall of the containing groove 10f limits the relative movement of the atomizer 10 and the additional oil tank 20, which is convenient for controlling the movement stroke of the two and is beneficial for the user to perceive that the main storage cavity 10a and the additional storage cavity 20a are in the connected state or the disconnected state.

[0174] In some embodiments, referring to Figure 3 , at least one side of the containing groove 10f open in the direction perpendicular to the second direction forms an entrance and exit, and at least part of the one of the atomizer 10 and the additional oil tank 20 which is not provided with the containing groove 10f can enter the containing groove 10f through the entrance and exit. In this way, the relative movement of the atomizer 10 and the additional oil tank 20 is adapted to the way of entering and exiting the containing groove 10f, which is convenient for the user to operate.

[0175] In some embodiments, referring to Figure 5 , Figure 8 and Figures 32 to 34At least part of the surface of the atomizer 10 near one end of the additional oil tank 20 is a third end surface 10g perpendicular to the second direction, and at least part of the surface of the additional oil tank 20 near one end of the atomizer 10 is a fourth end surface 20h perpendicular to the second direction. In a state in which the main storage cavity 10a and the additional storage cavity 20a are in communication, the third end surface 10g and the fourth end surface 20h abut along the second direction.

[0176] The third end surface 10g and the fourth end surface 20h are both planar.

[0177] The third end surface 10g and the fourth end surface 20h abut each other, which is conducive to increasing the contact area of the two and improving the stability of the movement of the atomizer 10 and the additional oil tank 20 relative to each other in the process of relative movement between the atomizer 10 and the additional oil tank 20 by using the third end surface 10g and the fourth end surface 20h to constrain each other along the second direction.

[0178] In some embodiments, referring to Figure 36 , Figure 35 The additional oil tank 20 includes a sealing member 24 and a housing assembly 21. The housing assembly 21 includes an insertion channel 21e and an additional storage cavity 20a. The insertion channel 21e communicates the additional storage cavity 20a and the outside of the housing assembly 21. The sealing member 24 includes a blocking portion 241 and an elastic return portion. The blocking portion 241 is arranged in the additional storage cavity 20a and blocks the insertion channel 21e. Part of the elastic return portion is fixed to the housing assembly 21. The insertion channel 21e is used for inserting the atomizer 10 into the insertion channel 21e to push the blocking portion 241 away from the insertion channel 21e. In a state in which the main storage cavity 10a and the additional storage cavity 20a are in communication, the blocking portion 241 is away from the insertion channel 21e, and the elastic return portion is elastically deformed to make the blocking portion 241 have a movement trend towards the insertion channel 21e to block the insertion channel 21e.

[0179] The blocking portion 241 is used for covering the opening of the position where the insertion hole and the additional storage cavity 20a are in communication.

[0180] In a state in which the blocking portion 241 blocks the insertion channel 21e, the insertion channel 21e is not in communication 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 channel 21e.

[0181] At least part of the atomizer 10 is inserted into the insertion channel 21e until the atomizer 10 abuts against the blocking portion 241, thereby pushing the blocking portion 241 to move, so that the blocking portion 241 is away from the insertion channel 21e to enable the atomizer 10 to be in communication with the additional storage cavity 20a, and the aerosol generating substrate in the additional storage cavity 20a can enter the atomizer 10.

[0182] The elastic reset portion can be elastically deformed under an external force to stretch and contract with the movement of the blocking portion 241.

[0183] It can be understood that the atomizer 10 drives the blocking portion 241 to move relative to the shell assembly 21 until the blocking portion 241 is out of contact with the shell assembly 21 to achieve the unblocking effect of the blocking portion 241 on the insertion channel 21e. During the movement of the blocking portion 241, the elastic reset portion elastically deforms to enable the part connected to the blocking portion 241 to move relative to the part fixed relative to the shell assembly 21, thereby enabling the elastic reset portion to exert an elastic force on the blocking portion 241.

[0184] In the state where the atomizer 10 abuts against the blocking portion 241, although the blocking portion 241 has a movement trend towards the insertion channel 21e due to the elastic force exerted by the elastic reset portion, the abutting force of the atomizer 10 on the blocking portion 241 balances the elastic force of the elastic reset portion on the blocking portion 241, so that the position of the blocking portion 241 is relatively fixed, and the aerosol generating substrate in the additional storage cavity 20a can flow into the atomizer 10 more stably; in the state where the additional cartridge 20 is separated from the atomizer 10 for replacement, the atomizer 10 is separated from the insertion channel 21e, so that the blocking portion 241 is no longer subjected to the abutting force exerted by the atomizer 10, and under the action of the elastic force of the elastic reset portion on the blocking portion 241, the sealing member 24 moves towards the insertion channel 21e until the blocking portion 241 abuts against the shell assembly 21 and re-blocks the insertion channel 21e.

[0185] It can be understood that after the atomizer 10 is separated from the insertion channel 21e, the elastic reset portion is in an elastically deformed state in the state where the blocking portion 241 blocks the insertion channel 21e, so that the blocking portion 241 maintains the state of blocking the insertion channel 21e.
