[0004] The aerosol generating device is used to generate aerosol for the user to inhale.

[0005] The aerosol-generating device includes an atomizer and an additional oil tank. The atomizer core absorbs an aerosol-generating substrate and converts it into an aerosol. When 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 its outlet to replenish the substrate, thereby extending the service life of the aerosol-generating device.

[0006] In the related art, the additional oil tank is detachably arranged with the atomizer so that after the aerosol-generating substrate in the additional oil tank is exhausted, the old additional oil tank can be removed and replaced with a new one.

[0007] After the additional oil tank is disassembled and separated from the atomizer, a small amount of aerosol-generating matrix remains. If this residual aerosol-generating matrix leaks, it may adhere to the user's clothing, personal belongings, hands, etc., which is not conducive to the user's experience and may also cause pollution to the surrounding environment.

[0040] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present invention can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the embodiments of the present invention and should not be regarded as an improper limitation on the embodiments of the present invention.

It should be understood that these directional terms are merely for the purpose of facilitating the description of the embodiments of the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed or operate in a specific direction. Therefore, they should not be construed as limiting the embodiments of the present invention.

[0042] The present invention provides an additional oil reservoir containing an aerosol-generating substrate. The additional oil reservoir is disposed within an aerosol-generating device and is used to supply the aerosol-generating substrate to the atomizer. After the aerosol-generating substrate stored in the aerosol-generating device is depleted, the additional oil reservoir can continue to replenish the aerosol-generating substrate, thereby extending the service life of the aerosol-generating device. The additional oil reservoir is detachably connected to other components of the aerosol-generating device, allowing replacement of the aerosol-generating substrate stored in the additional oil reservoir upon depletion.

[0043] See Figures 1 to 3 The additional oil tank 10 includes a housing assembly 11 and a sealing member 12 .

[0044] The housing assembly 11 is provided with an additional storage cavity 11 a and an insertion hole 11 b . The insertion hole 11 b communicates with the additional storage cavity 11 a and the outside of the additional oil tank 10 . The additional storage cavity 11 a is used to store the aerosol generating substrate.

[0045] The sealing member 12 includes a blocking portion 121 and an elastic reset portion 122. The blocking portion 121 is disposed in the additional storage chamber 11a and blocks the insertion hole 11b. Part of the elastic reset portion 122 is fixed relative to the housing assembly 11. The insertion hole 11b is used for inserting the atomizer 20 therein to push the blocking portion 121 out of the insertion hole 11b. When the blocking portion 121 is out of the insertion hole 11b, the elastic reset portion 122 is elastically deformed to cause the blocking portion 121 to move toward the insertion hole 11b to block the insertion hole 11b.

[0046] The aerosol-generating substrate is a fluid.

[0047] The blocking portion 121 is used to cover the opening at the position where the insertion hole 11 b communicates with the additional storage cavity 11 a.

[0048] When the blocking portion 121 blocks the insertion hole 11 b , the insertion hole 11 b is not connected to the additional storage chamber 11 a , and the aerosol generating substrate in the additional storage chamber 11 a cannot flow out of the additional oil tank 10 through the insertion hole 11 b .

[0049] At least part of the nebulizer 20 is inserted into the insertion hole 11b until it abuts against the blocking portion 121, thereby pushing the blocking portion 121 to move, so that the blocking portion 121 is disengaged from the insertion hole 11b so that the nebulizer 20 can be connected to the additional storage chamber 11a, and the aerosol generating matrix in the additional storage chamber 11a can enter the nebulizer 20.

[0050] The elastic restoring portion 122 can be elastically deformed under the action of an external force, so as to expand and contract along with the movement of the blocking portion 121 .

[0051] It is understood that the atomizer 20 pushes the blocking portion 121 to move relative to the housing assembly 11 until the blocking portion 121 disengages from the housing assembly 11, thereby releasing the blocking effect of the blocking portion 121 on the insertion hole 11b. During the movement of the blocking portion 121, the elastic return portion 122 elastically deforms so that the portion connected to the blocking portion 121 can move relative to the portion fixed to the housing assembly 11, thereby causing the elastic return portion 122 to apply an elastic force to the blocking portion 121.

[0052] When the nebulizer 20 is in contact with the sealing portion 121, although the sealing portion 121 has a tendency to move toward the insertion hole 11b due to the elastic force exerted by the elastic reset portion 122, the abutting force of the nebulizer 20 on the sealing portion 121 is balanced by the elastic force of the elastic reset portion 122 on the sealing portion 121, so that the position of the sealing portion 121 is relatively fixed, and the aerosol generating matrix in the additional storage chamber 11a can flow into the nebulizer 20 more stably; when the additional oil tank 10 is separated from the nebulizer 20 for replacement, the nebulizer 20 is detached from the insertion hole 11b, so that the sealing portion 121 is no longer subjected to the abutting force exerted on it by the nebulizer 20. Under the action of the elastic force of the elastic reset portion 122 on the sealing portion 121, the seal 12 moves toward the insertion hole 11b until the sealing portion 121 abuts against the shell assembly 11 and re-blocks the insertion hole 11b.

[0053] It is understandable that after the atomizer 20 is detached from the insertion hole 11b, when the blocking portion 121 blocks the insertion hole 11b, the elastic reset portion 122 is in an elastically deformed state so that the blocking portion 121 keeps blocking the insertion hole 11b.

[0054] The additional oil tank 10 in the embodiment of the present invention, through the elastic force exerted by the elastic reset portion 122 on the sealing portion 121, can, on the one hand, help maintain the position of the sealing portion 121 in the additional storage chamber 11a when the atomizer 20 is inserted into the insertion hole 11b, thereby reducing the abnormal noise generated by the shaking of the sealing portion 121 in the additional storage chamber 11a; on the other hand, it is convenient for the sealing portion 121 to re-seal the insertion hole 11b after the atomizer 20 is pulled out of the insertion hole 11b, thereby reducing the probability of leakage of the aerosol generating matrix in the additional storage chamber 11a after the additional oil tank 10 is removed from the aerosol generating device.

[0055] In some embodiments, the sealing portion 121 is made of food-grade silicone. This reduces the chance of contamination of the aerosol-generating substrate in the additional storage chamber 11a by the sealing portion 121. Furthermore, the elastic force exerted by the elastic return portion 122 on the sealing portion 121 allows the sealing portion 121 to deform elastically, thereby maintaining contact between the sealing portion 121 and the housing assembly 11 and improving the sealing effect of the sealing portion 121.

[0056] In some embodiments, see Figure 3 The elastic restoring portion 122 is located in the additional storage cavity 11 a. In this way, the elastic restoring portion 122 is prevented from being exposed to the outside of the housing assembly 11 and thus being damaged.

[0057] In some embodiments where the elastic restoring portion 122 is located in the additional storage cavity 11 a , the elastic restoring portion 122 is made of food-grade material, such as food-grade silicone, to reduce the probability of the sealing portion 121 contaminating the aerosol-generating substrate in the additional storage cavity 11 a .

[0058] In some embodiments, see Figure 4 and Figure 5 The number of the elastic reset parts 122 is multiple, so that when the elastic force of some of the elastic reset parts 122 fails, the elastic force can still be generated on the blocking part 121.

[0059] The plurality of elastic restoring portions 122 refers to the number of the elastic restoring portions 122 being no less than two.

[0060] In some embodiments where the number of the elastic restoring portion 122 is multiple, see Figures 3 to 5 The insertion hole 11b extends along the first direction, the elastic reset portion 122 extends perpendicular to the first direction, and the elastic reset portions 122 are evenly arranged around the blocking portion 121 with an axis extending along the first direction.

[0061] Under the guidance of the insertion hole 11 b , the atomizer 20 pushes the blocking portion 121 to move along the first direction, driving the elastic restoring portion 122 to stretch, thereby causing the elastic restoring portion 122 to generate an elastic force on the blocking portion 121 .

[0062] After the elastic reset portion 122 is stretched, the elastic force exerted by the elastic reset portion 122 on the sealing portion 121 can be decomposed into a first force component along the first direction and a second force component perpendicular to the first direction. The first force component enables the sealing portion 121 to move along the first direction. The uniform arrangement of the elastic reset portions 122 balances the second force components generated by each elastic reset portion 122, facilitating the stabilization of the position of the sealing portion 121 perpendicular to the first direction and ensuring that the sealing portion 121 accurately seals the insertion hole 11b after the atomizer 20 is removed from the insertion hole 11b.

[0063] The elastic reset portions 122 are evenly arranged, meaning that, in a projection perpendicular to the first direction, the angle between the geometric centers of the projected outlines of any two adjacent elastic reset portions 122 is the same. For example, if there are two elastic reset portions 122, the angle between the geometric centers of the projected outlines of the two elastic reset portions 122 is 180°; for example, if there are three elastic reset portions 122, the angle between the geometric centers of the projected outlines of the two elastic reset portions 122 is 120°; and if there are four elastic reset portions 122, the angle between the geometric centers of the projected outlines of the two elastic reset portions 122 is 90°.

[0064] In some embodiments, see Figure 5 The number of the elastic reset parts 122 is two, so as to simplify the structure of the sealing member 12 and reduce the production cost.

[0065] In the embodiment where the number of the elastic restoring portions 122 is two, the ratio of the dimension of the elastic restoring portion 122 along the second direction to the dimension of the elastic restoring portion 122 along the first direction is not less than 3, and the first direction, the second direction and the extension direction of the elastic restoring portion 122 are perpendicular to each other. Figure 3 and Figure 5 The dimension of the elastic reset portion 122 along the second direction is L1, the dimension of the elastic reset portion 122 along the first direction is L2, and L1 / L2≥3.

[0066] In this way, the elastic reset portion 122 can help suppress the probability of the blocking portion 121 flipping over along the axis perpendicular to the first direction, so that the blocking portion 121 can more smoothly block the insertion hole 11 b.

[0067] In some embodiments, see Figure 3 and Figure 5 The connection position between the elastic restoring portion 122 and the blocking portion 121 is located on a side of the blocking portion 121 away from the insertion hole 11 b along the first direction.

[0068] In this way, the probability of the elastic reset portion 122 interfering with the contact between the blocking portion 121 and the shell assembly 11 is reduced, which is beneficial to increasing the contact area between the elastic reset portion 122 and the blocking portion 121 to improve the connection strength while reducing the size of the blocking portion 121 along the first direction.

[0069] In some embodiments where the number of the elastic restoring portion 122 is multiple, see Figure 4 and Figure 5 The elastic reset portions 122 are connected to each other to improve the connection strength between the elastic reset portion 122 and the blocking portion 121 .

[0070] In some embodiments, see Figures 3 to 5 The shell assembly 11 includes a first shell 111 and a second shell 112, the seal 12 also includes a sealing portion 123, the elastic reset portion 122 is connected between the blocking portion 121 and the sealing portion 123, an installation space is provided in the second shell 112, one side of the installation space is open, the first shell 111 is covered at the open part of the installation space to form an additional storage cavity 11a together with the second shell 112, the sealing portion 123 is clamped between the first shell 111 and the second shell 112, and the insertion hole 11b is provided in at least one of the first shell 111 and the second shell 112.

[0071] The housing assembly 11 is formed by splicing a first housing 111 and a second housing 112. The joint between the first housing 111 and the second housing 112 is sealed by a sealing portion 123 to reduce the probability of leakage of the aerosol generating substrate from the joint.

[0072] The sealing portion 123 is sandwiched between the first housing 111 and the second housing 112 to secure the sealing portion 123 relative to the housing assembly 11. Furthermore, the elastic return portion 122 is connected to the sealing portion 123, securing a portion of the elastic sealing portion 123 relative to the housing assembly 11. This eliminates the need for adhesive bonding or other methods to secure the elastic return portion 122 to the housing assembly 11, simplifying the assembly process and improving assembly efficiency.

[0073] It is understandable that the sealing portion 123 is an annular structure so as to completely seal the joint between the first shell 111 and the second shell 112 , and the blocking portion 121 and the elastic reset portion 122 are located on the inner side of the sealing portion 123 .

[0074] The insertion hole 11 b may be provided separately in the first shell 111 ; may be provided separately in the second shell 112 ; or may be formed by combining the edges of the first shell 111 and the second shell 112 .

[0075] In some embodiments, the elastic reset portion 122 , the blocking portion 121 and the sealing portion 123 are an integrated structure, so as to reduce the number of parts and the number of assembly steps in the assembly process, thereby improving assembly efficiency.

[0076] It is understandable that the elastic reset portion 122 , the blocking portion 121 and the sealing portion 123 may be made of the same material so that the integrated structure can be formed simultaneously.

[0077] It is understandable that, when the atomizer 20 pushes the blocking portion 121 , the elastic reset portion 122 also generates an elastic force on the sealing portion 123 .

[0078] In some embodiments, see Figure 3 and Figure 4 The insertion hole 11b passes through the first shell 111, and the installation space is open on one side along the first direction. The insertion hole 11b extends along the first direction, and the inner wall of the installation space is provided with a stop rib 1121 extending along the first direction. The stop rib 1121 is located on the side of the sealing portion 123 away from the first shell 111 and cooperates with the sealing portion 123 to stop along the first direction.

[0079] When the elastic reset portion 122 is elastically deformed, the component of the elastic force applied by the elastic reset portion 122 to the sealing portion 123 along the first direction is opposite to the direction of the first direction applied by the stop rib 1121 to the sealing portion 123. In this way, the probability of the sealing portion 123 moving due to the elastic force of the elastic reset portion 122 pulling on the sealing portion 123 and affecting the sealing performance is reduced.

[0080] The number of the stop rib 1121 is not limited and can be one; Figure 4 , or multiple.

[0081] It can be understood that the blocking portion 121 blocks the insertion hole 11b by only covering the connection position between the insertion hole 11b and the additional storage chamber 11a; or a portion of the blocking portion 121 is embedded in the insertion hole 11b and sealed to a portion of the inner wall of the insertion hole 11b.

[0082] In some embodiments, the edges of the communication opening between the insertion hole 11 b and the additional storage cavity 11 a are chamfered so that the blocking portion 121 can be more smoothly inserted into the insertion hole 11 b to achieve blocking.

[0083] In some embodiments, the edge of the blocking portion 121 facing the insertion hole 11 b is chamfered so that the blocking portion 121 can be more smoothly inserted into the insertion hole 11 b to achieve blocking.

[0084] The chamfer can be in the form of a bevel or a rounded corner.

[0085] It is understandable that after the assembly of the housing assembly 11 is completed, the aerosol generating substrate needs to be injected into the additional storage chamber 11 a.

[0086] For example, the injection tube of the injection device is inserted into the insertion hole 11b and abuts against the sealing portion 121. This pushes the sealing portion 121 to move, releasing the sealing effect on the insertion hole 11b, thereby allowing the aerosol-generating substrate to be injected into the additional storage chamber 11a. After the injection is completed, the injection tube is removed, and the sealing portion 121 returns to its original position under the action of the elastic return portion 122, thus sealing the insertion hole 11b.

[0087] In some embodiments, see Figure 3 、 Figure 4 and Figure 6 The additional oil tank 10 also includes a sealing plug 13, which includes a sealing block 131. The shell assembly 11 is also provided with an injection hole 11c, which connects the additional storage chamber 11a and the outside of the additional oil tank 10. The sealing block 131 can block the injection hole 11c from the outside of the shell assembly 11.

[0088] In this way, when injecting the aerosol-generating substrate into the additional storage chamber 11a, the injection tube of the injection device can be first inserted into the injection hole 11c, and the aerosol-generating substrate can be directly injected into the additional storage chamber 11a, thereby avoiding the obstruction of the liquid flow by the blocking portion 121 and improving the injection efficiency. Moreover, during the injection process, the insertion hole 11b does not need to be opened. The blocking portion 121 can be installed into the insertion hole 11b before the injection with an external force greater than the force applied by the elastic return portion 122, thereby achieving a better sealing effect and preventing leakage of the additional oil tank 10 during transportation (i.e., before installation in the atomizer 20).

[0089] It is understandable that at least a portion of the sealing block 131 is embedded in the injection hole 11 c and is sealed against at least a portion of the inner wall of the injection hole 11 c, so as to reduce the probability of leakage of the aerosol generating substrate from the injection hole 11 c.

[0090] The sealing block 131 is made of food-grade material, such as food-grade silicone, to reduce the probability of the sealing block 131 contaminating the aerosol-generating matrix in the additional storage chamber 11a; at the same time, the elastic deformation of the sealing block 131 can also improve the sealing effect of the injection hole 11c.

[0091] It is understandable that after the nebulizer 20 is inserted into the insertion hole 11b, there is a gap between it and the inner wall of the insertion hole 11b, so that the nebulizer 20 can be smoothly inserted and subsequently removed. However, the gap between it and the inner wall of the insertion hole 11b poses a risk of leakage of the aerosol generating matrix.

[0092] In some embodiments, see Figure 3 and Figure 6 The sealing plug 13 includes a sealing ring 132, which is provided with a penetrating avoidance hole 132a. At least a portion of the sealing ring 132 is located in the insertion hole 11b and is sealed and fitted with the inner wall of the insertion hole 11b. The avoidance hole 132a is used for the atomizer 20 to be inserted into the interior thereof to enter the insertion hole 11b.

[0093] It is understandable that at least a portion of the inner wall of the avoidance hole 132a is used to seal against the nebulizer 20 to reduce the risk of the aerosol generating substrate leaking from between the nebulizer 20 and the inner wall of the insertion hole 11b.

[0094] In some embodiments, see Figure 6 The inner wall of the avoidance hole 132a is provided with a sealing protrusion, which is used to seal with the atomizer 20 to improve the sealing effect.

[0095] The sealing block 131 is made of food-grade material, such as food-grade silicone, to reduce the probability of the sealing block 131 contaminating the aerosol-generating matrix in the additional storage chamber 11a; at the same time, the elastic deformation of the sealing block 131 can also improve the sealing effect of the avoidance hole 132a.

[0096] In some embodiments, see Figure 6 The sealing ring 132 is an annular structure to improve the sealing effect.

[0097] In some embodiments, see Figure 6 The sealing plug 13 includes a sealing seat 133 , a sealing block 131 and a sealing ring 132 are both arranged on the sealing seat 133 , and the sealing plug 13 is an integrated structure, which is beneficial to reducing the number of parts of the additional oil tank 10 .

[0098] In some embodiments having a first housing 111 and a second housing 112, see Figure 3 The injection hole 11c and the insertion hole 11b are located on the same part of the first shell 111 and the second shell 112, and both the injection hole 11c and the insertion hole 11b extend along the first direction. This helps reduce the distance between the sealing ring 132 and the sealing block 131, thereby reducing the size of the sealing plug 13.

[0099] The present invention also provides an aerosol generating device. Figures 7 to 10 The aerosol generating device includes an atomizer 20 and any of the additional oil tanks 10 in the aforementioned embodiments. The atomizer 20 includes a mounting assembly 21 and an atomizer core 22. The mounting assembly 21 is provided with a accommodating chamber 21a, and the accommodating chamber 21a is provided with an atomizer core 22. The mounting assembly 21 is provided with a plug-in column 211, and the plug-in column 211 is provided with an exchange channel 211a. The exchange channel 211a connects the accommodating chamber 21a and the outside of the atomizer 20. The plug-in column 211 is provided with an exchange hole 211b. The exchange hole 211b passes through the plug-in column 211. When the plug-in column 211 pushes the blocking portion 121 out of the plug-in hole 11b, the exchange hole 211b connects the exchange channel 211a with the additional storage chamber 11a.

[0100] The atomizing core 22 is used to convert the aerosol-generating matrix into aerosol by heating or other means. The aerosol is discharged from the atomizer 20 and is then inhaled by the user.

[0101] The insertion post 211 is inserted into the insertion hole 11b and abuts against the blocking portion 121 to push the blocking portion 121 out of contact with the housing assembly 11, and at least a portion of the exchange hole 211b enters the additional storage chamber 11a. The aerosol generating substrate in the additional storage chamber 11a enters the exchange channel 211a through the exchange hole 211b, and then enters the accommodating chamber 21a and is absorbed by the atomizer core 22, thereby extending the service life of the atomizer core 22; at the same time, the gas in the accommodating chamber 21a can enter the additional storage chamber 11a through the exchange channel 211a and the exchange hole 211b, thereby reducing the probability of negative pressure in the additional storage chamber 11a and inhibiting the aerosol generating substrate from entering the exchange channel 211a through the exchange hole 211b, so that the aerosol generating substrate can be replenished in time.

[0102] In some embodiments, one end of the exchange channel 211a close to the blocking portion 121 is a closed end, and the end of the insertion column 211 inserted into the additional storage cavity 11a can abut against the blocking portion 121, thereby increasing the contact area between the insertion column 211 and the blocking portion 121, which is beneficial for maintaining the relative position of the two stable and reducing the risk of the blocking portion 121 covering the exchange hole 211b due to shaking or vibration during use of the aerosol generating device.

[0103] In other embodiments, see Figure 10 and Figure 11 The end of the exchange channel 211a close to the blocking portion 121 is an open end, so that a part of the blocking portion 121 can be embedded in the exchange channel 211a, thereby limiting the position of the blocking portion 121 through the inner wall of the exchange channel 211a, reducing the risk of the blocking portion 121 covering the exchange hole 211b due to shaking or vibration of the aerosol generating device during use.

[0104] In some embodiments, the atomizer 20 and the additional oil tank 10 are detachably connected.

[0105] The specific method of achieving detachable connection is not limited. For example, one of the atomizer 20 and the additional oil tank 10 is provided with an elastic clip, and the other is provided with a mounting groove. The elastic clip can be embedded in the mounting groove or removed from the mounting groove through elastic deformation.

[0106] Understandably, see Figure 10 , the insertion column 211 is inserted into the avoidance hole 132a.

[0107] In some embodiments, see Figure 9 and 10 The insertion column 211 and the insertion hole 11b both extend along the first direction, and the exchange hole 211b is located on a side of the insertion column 211 that is perpendicular to the first direction.

[0108] The insertion column 211 abuts against the blocking portion 121 along the first direction, thereby reducing the probability of the blocking portion 121 blocking the exchange hole 211b, facilitating smooth flow of aerosol-generating substrate and airflow between the exchange channel 211a and the additional storage chamber 11a.

[0109] In some embodiments, see Figure 10 and Figure 11 The exchange hole 211b is open on one side of the blocking portion 121 along the first direction, so that after the insertion column 211 enters the additional storage chamber 11a, the aerosol generating matrix can immediately enter the exchange channel 211a, which is beneficial to improving the replenishment speed of the aerosol generating matrix and also facilitates shortening the size of the insertion column 211 along the first direction, which is beneficial to making the structure of the atomizer 20 more compact.

[0110] The number of the exchange holes 211b may be one or more.

[0111] In some embodiments where the exchange hole 211b is multiple, see Figure 10 and Figure 11 At least part of the exchange holes 211b are located above the exchange channel 211a along the axial direction of the aerosol generating device.

[0112] The axial direction of the aerosol generating device refers to the direction in which the aerosol exits the aerosol generating device. When a user uses the aerosol generating device, the axial direction of the aerosol generating device is substantially along the vertical direction.

[0113] The upper side of the exchange channel 211 a refers to a direction of the exchange channel 211 a away from the direction of gravity when the user uses the aerosol generating device.

[0114] When a user uses the aerosol generating device, since the density of the gas in the exchange channel 211 a is lower than that of the aerosol generating matrix, bubbles formed by the gas are more likely to gather above the exchange channel 211 a.

[0115] In this way, it is easy for bubbles to enter the additional storage chamber 11 a from the exchange hole 211 b, thereby further reducing the probability of negative pressure in the additional storage chamber 11 a.

[0116] In some embodiments, see Figure 8 and Figure 9 An air outlet channel 21b is provided in the mounting assembly 21, and the air outlet channel 21b connects the atomizing cavity in the atomizing core 22 and the outside of the atomizer 20. The axial direction of the inserting column 211 is perpendicular to the air outlet direction of the air outlet channel.

[0117] The axial direction of the insertion column 211 refers to the direction in which the insertion column 211 is inserted into the additional storage cavity 11 a .

[0118] In this way, when the user inhales the aerosol, it is helpful to reduce the height difference between the liquid level of the aerosol generating matrix in the additional storage chamber 11a and the atomizer core 22 in the direction of gravity, thereby reducing the risk of leakage caused by the pressure generated by the height difference of the aerosol generating matrix acting on the atomizer core 22, which is helpful to improve the anti-leakage effect of the aerosol generating matrix.

[0119] When the user inhales the aerosol, the aerosol generated by the atomizer core 22 enters the atomizer chamber and is then discharged from the outlet of the air outlet channel 21b into the user's mouth. In this state, the third direction is generally vertical, that is, the third direction is parallel to the direction of gravity or forms an acute angle with the direction of gravity.

[0120] In some embodiments, the extension direction of the elastic return portion 122, the first direction, and the axial direction of the aerosol generating device are perpendicular to one another. Thus, if there are two elastic return portions 122 and they are evenly spaced, the insertion hole 11b can be positioned as far below the additional oil tank 10 as possible, allowing the aerosol-generating substrate in the additional storage chamber 11a to flow out of the additional storage chamber 11a as much as possible under the action of gravity.

[0121] In some embodiments, see Figure 9 The atomizer core 22 and the inner wall of the accommodating chamber 21a together form a main storage chamber 21c, which is connected to the exchange channel 211a. The atomizer 20 also includes a liquid storage member 23 located within the main storage chamber 21c. The liquid storage member 23 has pores that allow it to absorb the aerosol-forming substrate through capillary action. Furthermore, due to the presence of the liquid storage member 23, when the additional oil tank 10 is removed, the aerosol-forming substrate in the main storage chamber 21c will not flow directly to the atomizer core 22 due to gravity, causing leakage.

[0122] The liquid storage member 23 has a plurality of pores. After the liquid storage member 23 comes into contact with the aerosol-generating substrate, the aerosol-generating substrate can be absorbed by the liquid storage member 23 through capillary action and stored in the space within the pores. At least some of the pores are interconnected, so that the aerosol-generating substrate can pass through the liquid storage member 23 and be transported to the atomizer core 22 in fluid communication with the liquid storage member 23.

[0123] In this way, after the aerosol-generating substrate on the atomizer core 22 is consumed to a certain extent, the aerosol-generating substrate can be replenished to the atomizer core 22 through the liquid reservoir 23, so that the concentration of the aerosol-generating substrate in the atomizer core 22 is maintained within a certain range. At the same time, due to the presence of pores, airflow can also pass through the liquid reservoir 23 via the interconnected pores. In other words, the channels formed by the interconnected pores in the liquid reservoir 23 allow both airflow and aerosol-generating substrate to flow through.

[0124] The aerosol-generating substrate in the additional storage chamber 11 a enters the main storage chamber 21 c and is absorbed by the liquid storage member 23 , and then supplied to the atomizer core 22 through the liquid storage member 23 .

[0125] The various embodiments / implementations of the present invention can be combined with each other without causing any contradiction.
