[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.

[0038] 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.

[0039] In the description of the embodiment of the present invention, the "first direction" orientation or position relationship is based on the attached Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 The direction or position relationship shown by the arrow X in the middle; the direction or position relationship of the "second direction" is based on the attached Figures 1 to 3 、 Figure 5 、 Figure 7 The orientation or position relationship is shown by the arrow Y in the figure. It should be understood that these orientation terms are only used to facilitate the description of the embodiments of the present invention and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present invention.

[0040] The present invention provides an aerosol generating device. Figures 1 to 4 The aerosol generating device includes an atomizer 20 and an additional oil tank 10.

[0041] The atomizer 20 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.

[0042] The atomizer 20 includes an air outlet channel 21 b and a main storage chamber 21 c. The air outlet channel 21 b communicates with the outside of the aerosol generating device and extends along a first direction.

[0043] The main storage chamber 21c stores an aerosol-generating substrate. The atomizer 20 heats the aerosol-generating substrate stored in the main storage chamber 21c and converts it into an aerosol. The generated aerosol enters the air outlet passage 21b and exits the aerosol-generating device through the outlet of the air outlet passage 21b for inhalation by the user.

[0044] It can be understood that the main storage chamber 21c and the air outlet channel 21b are isolated from each other.

[0045] The air outlet channel 21b extends along a first direction, that is, the flow direction of the aerosol in the air outlet channel 21b and the flow direction out of the aerosol generating device are the first direction.

[0046] The additional oil reservoir 10 is located on one side of the atomizer 20 along the second direction, where the first and second directions intersect. In other words, the additional oil reservoir 10 is located on one side of the outlet channel 21b along the second direction, and is not located on one side of the atomizer 20 along the first direction. This advantageously eliminates the need for aerosol discharged from the atomizer 20 through the outlet channel 21b to pass through the additional oil reservoir 10 before leaving the aerosol generating device, thereby shortening the airflow path in the outlet channel 21b.

[0047] The additional oil tank 10 is provided with an additional storage chamber 11 a and a liquid inlet channel 11 b.

[0048] The additional storage chamber 11 a is used to store the aerosol-generating substrate.

[0049] The additional oil tank 10 can move relative to the atomizer 20 to switch the aerosol generating device between an on state and a off state; in the on state, the liquid inlet channel 11b is opened to connect the main storage chamber 21c and the additional storage chamber 11a; in the off state, the liquid inlet channel 11b is closed to isolate the main storage chamber 21c and the additional storage chamber 11a.

[0050] That is to say, the liquid inlet channel 11b can only be opened or closed through the relative movement between the additional oil tank 10 and the atomizer 20, and the liquid inlet channel 11b cannot be opened or closed by separately controlling the components in the additional oil tank 10 or the components in the atomizer 20.

[0051] It is understandable that the aerosol generating device is in the on state only when the additional oil tank 10 moves relative to the atomizer 20 to within a specific spatial range; outside the specific spatial range, the aerosol generating device is in the off state.

[0052] The aerosol generating device in the embodiment of the present application, on the one hand, by making the direction of the additional oil tank 10 relative to the atomizer 20 different from the extension direction of the air outlet channel 21b, is conducive to shortening the length of the air flow path in the air outlet channel 21b, thereby helping to reduce the condensation generated by the aerosol in the air outlet channel 21b, and helping to improve the user experience; on the other hand, by controlling the relative movement between the additional oil tank 10 and the atomizer 20, it is conducive to the user to adjust the amount of aerosol generating matrix added to the main storage chamber 21c from the additional storage chamber 11a as needed, which is conducive to reducing the adverse effect of excessive aerosol generating matrix in the main storage chamber 21c on the taste of the generated aerosol, and is also conducive to reducing the probability of leakage of the aerosol generating matrix in the discarded additional oil tank 10.

[0053] It is understood that the specific manner in which the additional oil tank 10 moves relative to the atomizer 20 is not limited. The additional oil tank 10 may rotate relative to the atomizer 20, or the additional oil tank 10 may translate relative to the atomizer 20 along a linear direction, for example, along the second direction, to switch the aerosol generating device between the on and off states.

[0054] In some embodiments, see Figure 1 and Figure 3 In the projection range perpendicular to the first direction, at least part of the projection of the additional oil tank 10 is located outside the projection range of the atomizer 20, so as to reduce the total size of the aerosol generating device along the first direction and improve the portability of the aerosol generating device.

[0055] In some embodiments, the nebulizer 20 and the additional oil tank 10 are detachably connected so that the additional oil tank 10 can be replaced with a new one after the aerosol-generating substrate in the additional oil tank 10 is exhausted.

[0056] 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 buckle, and the other is provided with a slot. The elastic buckle can be embedded in the slot or removed from the slot through elastic deformation.

[0057] In some embodiments, see Figure 1 and Figure 3 The aerosol generating device further includes a power supply assembly 30, which can be electrically connected to the atomizer 20. In this way, the atomizer 20 is powered by the power supply assembly 30 so that the atomizer 20 can operate normally.

[0058] The power supply assembly 30 includes a battery. The specific type of the battery is not limited, such as a lithium battery.

[0059] In some embodiments, the power supply assembly 30 , the atomizer 20 , and the additional oil tank 10 are detachably connected to each other.

[0060] That is to say, the power supply assembly 30 and the atomizer 20 may be detachably connected; the atomizer 20 and the additional oil tank 10 may be detachably connected; or the power supply assembly 30 and the additional oil tank 10 may be detachably connected.

[0061] This is beneficial for replacing the power supply assembly 30, the atomizer 20 and the additional oil tank 10 when they are damaged, which is beneficial for extending the service life of the aerosol generating device, is beneficial to environmental protection, and reduces the user's usage cost.

[0062] In some embodiments, see Figures 1 to 3 、 Figure 5 The atomizer 20 includes a mouthpiece 23, which is provided with an air outlet 23a extending along a first direction. The air outlet 23a forms at least a portion of the air outlet channel 21b and the outlet of the air outlet 23a is the outlet of the air outlet channel 21b. The mouthpiece 23 is used for the user to inhale.

[0063] This helps shorten the flow path length of the aerosol from its generation position in the atomizer 20 to the user's mouth during the user's aerosol inhalation process, thereby improving the user experience.

[0064] In some embodiments, see Figure 5 The mouthpiece 23 is located at one end of the atomizer 20 along the first direction to reduce interference caused by the power supply assembly 30 when the user inhales the aerosol.

[0065] In some embodiments, see Figure 3 and Figure 5 The atomizer 20 includes a mounting groove 20a, which is located on one side of the air outlet channel 21b along the second direction. The mounting groove 20a is open on a side away from the air outlet channel 21b, and at least a portion of the additional oil tank 10 is located in the mounting groove 20a.

[0066] That is, one side of the mounting groove 20a along the second direction is open.

[0067] In this way, on the one hand, the inner wall of the mounting groove 20a can be used to provide a certain degree of protection for the additional oil tank 10, thereby reducing the risk of leakage of the additional oil tank 10 due to collision; on the other hand, the inner wall of the mounting groove 20a can guide and limit the relative movement between the additional oil tank 10 and the atomizer 20, thereby improving the convenience for the user to operate the aerosol generating device to switch between the on state and the off state.

[0068] In some embodiments, see Figure 1 and Figure 3 The additional oil tank 10 cover is arranged at the opening of the mounting groove 20a to reduce the probability that foreign matter enters the mounting groove 20a and blocks the relative movement between the additional oil tank 10 and the atomizer 20 when the user uses the aerosol generating device.

[0069] In some embodiments where a power supply assembly 30 is provided, see Figure 1 The power supply assembly 30 is located on the outlet side of at least one of the atomizer 20 and the additional oil tank 10 away from the outlet channel 21b along the first direction.

[0070] That is to say, the power supply assembly 30 may be located only on the outlet side of the atomizer 20 away from the air outlet channel 21b along the first direction, may be located only on the outlet side of the additional oil tank 10 away from the air outlet channel 21b along the first direction, or may be located on the outlet side of the atomizer 20 and the additional oil tank 10, both away from the outlet side of the air outlet channel 21b along the first direction.

[0071] In this way, the aerosol discharged from the atomizer 20 through the air outlet channel 21b does not need to pass through the power supply assembly 30 before leaving the aerosol generating device, thereby shortening the length of the air flow path in the air outlet channel 21b; and reducing the interference caused by the power supply assembly 30 when the user inhales the aerosol.

[0072] In some embodiments, see Figure 3 、 Figure 6 and Figure 7 , the first direction is perpendicular to the second direction, and the liquid inlet channel 11b extends along the second direction.

[0073] This is beneficial for further reducing the size of the aerosol generating device along the first direction, making the structure of the aerosol generating device more compact.

[0074] In some embodiments, the first direction is perpendicular to the second direction and the liquid inlet channel 11b extends along the second direction. Figure 7 In the conducting state, in a projection perpendicular to the second direction, the projection of the liquid inlet channel 11b is located within the projection range of the additional storage chamber 11a.

[0075] In this way, it is beneficial to reduce the size of the additional oil tank 10 along the first direction, thereby facilitating the reduction of the size of the aerosol generating device along the first direction.

[0076] In some embodiments, the first direction is perpendicular to the second direction and the liquid inlet channel 11b extends along the second direction. Figure 3 , the projection of the liquid inlet channel 11b is located within the projection range of the main storage chamber 21c.

[0077] In this way, the size of the aerosol generating device along the first direction is reduced, which helps to make the structure of the aerosol generating device more compact.

[0078] It is understood that, when a user uses the aerosol generating device, the first direction is substantially along the vertical direction, ie, the linear direction where gravity lies.

[0079] In some embodiments, the first direction is perpendicular to the second direction and the liquid inlet channel 11b extends along the second direction. Figure 7 The distance between the inner wall of the additional storage chamber 11a on the side closer to the outlet of the air outlet channel 21b along the first direction and the inner wall of the liquid inlet channel 11b on the side closer to the outlet of the air outlet channel 21b along the first direction is a first distance, and the distance between the inner wall of the additional storage chamber 11a on the side farther from the outlet of the air outlet channel 21b along the first direction and the inner wall of the liquid inlet channel 11b on the side farther from the outlet of the air outlet channel 21b along the first direction is a second distance. The first distance and the second distance are not equal. In other words, D1 ≠ D2, and can be either D1>D2 or D1<D2.

[0080] See Figure 7 When D1>D2 and the first direction is substantially vertical, the connection between the liquid inlet channel 11b and the additional storage chamber 11a is closer to the bottom wall of the additional storage chamber 11a than to the top wall of the additional storage chamber 11a. This allows the aerosol-generating substrate in the additional storage chamber 11a to flow more fully through the liquid inlet channel 11b into the main storage chamber 21c in the connected state due to gravity, thereby improving the utilization of the aerosol-generating substrate in the additional storage chamber 11a and reducing waste.

[0081] See Figure 7When D1 < D2 and the first direction is substantially vertical, the connection point between the liquid inlet channel 11b and the additional storage chamber 11a is closer to the top wall of the additional storage chamber 11a than to the bottom wall of the additional storage chamber 11a. This facilitates the flow of the aerosol-generating substrate within the additional storage chamber 11a below the connection point between the liquid inlet channel 11b and the additional storage chamber 11a due to gravity, preventing the liquid level of the aerosol-generating substrate within the additional storage chamber 11a from flowing directly out of the additional storage chamber 11a. This requires the user to adjust the position of the aerosol-generating device to allow the aerosol-generating substrate within the additional storage chamber 11a to enter the main storage chamber 21c. For example, by inverting the aerosol-generating device so that the outlet of the air outlet channel 21b faces downward, which helps to reduce the adverse effect of excessive aerosol-generating substrate within the main storage chamber 21c on the taste of the generated aerosol.

[0082] The specific method for opening and closing the liquid inlet channel 11b is not limited.

[0083] For example, see Figure 3 、 Figure 4 、 Figures 8 to 11 The additional oil tank 10 includes a shell assembly 11 and a sealing member 12. The shell assembly 11 is provided with an additional storage chamber 11a and a liquid inlet channel 11b; the sealing member 12 includes a sealing portion 121 and an elastic reset portion 122. The sealing portion 121 is provided in the additional storage chamber 11a and blocks the liquid inlet channel 11b. Part of the elastic reset portion 122 is fixed relative to the shell assembly 11. The liquid inlet channel 11b is used for inserting the atomizer 20 therein to push the sealing portion 121 out of the liquid inlet channel 11b. In the conducting state, the sealing portion 121 is out of the liquid inlet channel 11b, and the elastic reset portion 122 generates elastic deformation to cause the sealing portion 121 to generate a movement trend toward the liquid inlet channel 11b to block the liquid inlet channel 11b.

[0084] The blocking portion 121 is used to cover the opening where the liquid inlet channel 11 b communicates with the additional storage chamber 11 a .

[0085] When the blocking portion 121 blocks the liquid inlet channel 11 b , the liquid inlet channel 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 liquid inlet channel 11 b .

[0086] At least part of the nebulizer 20 is inserted into the liquid inlet channel 11b until it abuts against the blocking portion 121, thereby pushing the blocking portion 121 to move, so that the blocking portion 121 is separated from the liquid inlet channel 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.

[0087] 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 .

[0088] 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 is disengaged from the housing assembly 11, thereby releasing the blocking effect of the blocking portion 121 on the liquid inlet channel 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.

[0089] When the nebulizer 20 is in contact with the sealing portion 121, although the sealing portion 121 has a tendency to move toward the liquid inlet channel 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 liquid inlet channel 11b, so that the sealing portion 121 is no longer subjected to the abutting force exerted on it by the nebulizer 20, and under the action of the elastic force of the elastic reset portion 122 on the sealing portion 121, the seal 12 moves toward the liquid inlet channel 11b until the sealing portion 121 abuts against the shell assembly 11 and re-blocks the liquid inlet channel 11b.

[0090] It is understandable that after the atomizer 20 is detached from the liquid inlet channel 11b, when the blocking portion 121 blocks the liquid inlet channel 11b, the elastic reset portion 122 is in an elastically deformed state so that the blocking portion 121 maintains the state of blocking the liquid inlet channel 11b.

[0091] In this way, on the one hand, when the atomizer 20 is inserted into the liquid inlet channel 11b, it is helpful to maintain the position of the sealing portion 121 in the additional storage chamber 11a, 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 liquid inlet channel 11b after the atomizer 20 is pulled out from the liquid inlet channel 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.

[0092] In some embodiments, see Figures 3 to 5The atomizer 20 includes a mounting assembly 21 and an atomizer core 22. A accommodating chamber 21a is provided in the mounting assembly 21. The atomizer core 22 is provided in the accommodating chamber 21a. The atomizer core 22 and the inner wall of the accommodating chamber 21a form a main storage chamber 21c. The mounting assembly 21 is provided with a plug-in column 211. An exchange channel 211a is provided in the plug-in column 211. The exchange channel 211a connects the main storage chamber 21c 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. In the conductive state, the exchange hole 211b connects the exchange channel 211a with the additional storage chamber 11a.

[0093] 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.

[0094] The insertion column 211 is inserted into the liquid inlet channel 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.

[0095] In some embodiments, see Figures 3 to 5 The insert post 211 and the liquid inlet channel 11b both extend in the second direction. This allows the aerosol generating device to switch between an on and off state by linearly moving the atomizer 20 and the additional oil reservoir 10 in the first direction. The cooperation between the insert post 211 and the inner wall of the liquid inlet channel 11b guides and limits the movement of the atomizer 20 and the additional oil reservoir 10 in the second direction, facilitating user operation.

[0096] In some embodiments, see Figure 5 The insert column 211 is provided with exchange holes 211b on both sides along the first direction. In this way, when the outlet of the air outlet channel 21b is facing upward or downward, the aerosol generating substrate in the additional storage chamber 11a can smoothly enter the exchange channel 211a under the action of gravity.

[0097] In some embodiments where a nozzle piece 23 is provided, see Figure 5 The suction nozzle 23 is provided on one side of the mounting assembly 21 along the first direction.

[0098] In some embodiments with mounting slots 20a, see Figure 5 The mounting groove 20a is located on one side of the mounting assembly 21 along the second direction.

[0099] In some embodiments, see Figure 9 and Figure 11 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.

[0100] The multiple elastic restoring portions 122 means that the number of the elastic restoring portions 122 is not less than 2.

[0101] In some embodiments where the number of the elastic restoring portion 122 is multiple, see Figures 3 to 5 The liquid inlet channel 11b extends along the second direction, the elastic reset portion 122 extends perpendicular to the second direction, and the elastic reset portions 122 are evenly arranged around the blocking portion 121 with an axis extending along the second direction.

[0102] Under the guidance of the liquid inlet channel 11 b , the atomizer 20 pushes the blocking portion 121 to move along the second 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 .

[0103] 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 second direction and a second force component perpendicular to the second direction. Under the action of the first force component, the sealing portion 121 can move along the second 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 second direction and enabling the sealing portion 121 to accurately seal the liquid inlet channel 11b after the atomizer 20 is removed from the liquid inlet channel 11b.

[0104] The elastic reset portions 122 are evenly arranged, meaning that, in a projection perpendicular to the second 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°.

[0105] In some embodiments, see Figure 7 and Figure 8 The connection position between the elastic reset portion 122 and the blocking portion 121 is located on a side of the blocking portion 121 away from the liquid inlet channel 11 b along the second direction.

[0106] 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 second direction.

[0107] In some embodiments where the number of the elastic restoring portion 122 is multiple, see Figure 8 and Figure 9 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 .

[0108] In some embodiments, see Figure 8 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 chamber 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 liquid inlet channel 11b is provided in at least one of the first shell 111 and the second shell 112.

[0109] 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.

[0110] 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.

[0111] 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 .

[0112] The liquid inlet channel 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 .

[0113] 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.

[0114] In some embodiments, see Figures 6 to 9 The liquid inlet channel 11b passes through the first shell 111, and the installation space is open on one side along the second direction. The liquid inlet channel 11b extends along the second direction, and the inner wall of the installation space is provided with a stop rib 1121 extending along the second 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 second direction.

[0115] 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 second direction is opposite to the direction of the second 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.

[0116] The number of the stop rib 1121 is not limited and can be one; Figure 7 and Figure 9 , or multiple.

[0117] In some embodiments, the edge of the communication port between the liquid inlet channel 11 b and the additional storage chamber 11 a is chamfered so that the blocking portion 121 can be more smoothly inserted into the liquid inlet channel 11 b to achieve blocking.

[0118] In some embodiments, the edge of the blocking portion 121 facing the liquid inlet channel 11 b is chamfered so that the blocking portion 121 can be more smoothly inserted into the liquid inlet channel 11 b to achieve blocking.

[0119] 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.

[0120] For example, the injection tube of the injection device is inserted into the liquid inlet channel 11b and abuts against the blocking portion 121. This pushes the blocking portion 121 to move, releasing the blocking effect on the liquid inlet channel 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 blocking portion 121 is reset by the elastic reset portion 122, thereby sealing the liquid inlet channel 11b.

[0121] In some embodiments, see Figure 8 、 Figure 10 and Figure 12 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.

[0122] 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, there is no need to open the liquid inlet channel 11b. The blocking portion 121 can be installed in the liquid inlet channel 11b before injection with an external force greater than the force applied by the elastic reset 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).

[0123] 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.

[0124] 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.

[0125] It can be understood that after the nebulizer 20 is inserted into the liquid inlet channel 11b, there is a gap between it and the inner wall of the liquid inlet channel 11b, so that the nebulizer 20 can be smoothly inserted and subsequently removed. However, the gap between it and the inner wall of the liquid inlet channel 11b poses a risk of leakage of the aerosol-generating matrix.

[0126] In some embodiments, see Figure 8 and Figure 12 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 liquid inlet channel 11b and is sealed and fitted with the inner wall of the liquid inlet channel 11b. The avoidance hole 132a is used for the atomizer 20 to be inserted into the interior thereof to enter the liquid inlet channel 11b.

[0127] 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 liquid inlet channel 11b.

[0128] In some embodiments, see Figure 12 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.

[0129] 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.

[0130] In some embodiments, see Figure 12 The sealing ring 132 is an annular structure to improve the sealing effect.

[0131] In some embodiments, see Figure 12 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 .

[0132] In some embodiments having a first housing 111 and a second housing 112, see Figure 8 The injection hole 11c and the liquid inlet channel 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 liquid inlet channel 11b extend along the second 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.

[0133] 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.

[0134] In other embodiments, see Figure 3 and Figure 5 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.

[0135] In some embodiments, see Figure 4 and Figure 5The exchange hole 211b is open on one side of the blocking portion 121 along the second 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 second direction, which is beneficial to making the structure of the atomizer 20 more compact.

[0136] The number of the exchange holes 211b may be one or more.

[0137] In some embodiments, see Figure 3 The atomizer 20 also includes a liquid reservoir 24 located within the main storage chamber 21c. The liquid reservoir 24 has pores that allow it to absorb the aerosol-forming substrate through capillary action. Furthermore, due to the presence of the liquid reservoir 24, when the additional oil tank 10 is removed, the aerosol-forming substrate in the main storage chamber 21c does not flow directly to the atomizer core 22 due to gravity, potentially causing leakage.

[0138] The liquid storage element 24 is in fluid communication with the atomizer core 22 .

[0139] The liquid storage member 24 has a plurality of pores. After the liquid storage member 24 contacts the aerosol-generating substrate, the aerosol-generating substrate can be absorbed by the liquid storage member 24 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 24 and be transported to the atomizer core 22 in fluid communication with the liquid storage member 24.

[0140] 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 24, 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 24 via the interconnected pores. In other words, the channels formed by the interconnected pores in the liquid reservoir 24 allow both airflow and aerosol-generating substrate to flow through.

[0141] 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 24 , and then supplied to the atomizer core 22 through the liquid storage member 24 .

[0142] The various embodiments / implementations of the present invention can be combined with each other without causing any contradiction.
