[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0053] First, the existing aerosol generating device mainly includes a battery assembly, an atomization assembly, and an atomization cartridge. The battery assembly is used to provide electrical energy to the atomization assembly, and the atomization cartridge is used to provide atomization liquid to the atomization assembly. The atomization assembly converts electrical energy into heat energy, and then atomizes the atomization liquid into aerosol. When the user inhales, the external air is mixed with the aerosol and flows into the user's mouth through the air flow channel in the atomization cartridge. However, in the related art, the airway structure in the atomization cartridge is relatively complex and needs to be formed by complex mold injection molding or assembled through a relatively complex assembly process, resulting in inconvenient production of the atomization cartridge.

[0054] To solve the above technical problems, according to the first aspect of the present application, an atomization cartridge 100 is provided, as Figure 1 shown. The atomization cartridge 100 mainly includes a housing 10 and a liquid cup 20.

[0055] Among them, reference can be made to Figure 3 and Figure 4 . Figure 3 is a schematic structural diagram of the housing 10, Figure 4 is Figure 3 a structural cross-sectional view of the housing 10 in Figure 3 . The housing 10 is provided with an installation cavity 11, an installation opening 12, and an air outlet hole 13. The installation opening 12 and the air outlet hole 13 are respectively located at both ends of the installation cavity 11 and are respectively communicated with the installation cavity 11. Specifically, the overall external habit of the housing 10 is approximately a cuboid block. Therefore, reference can be made to Figure 3 for the direction indication. The housing 10 has opposite height, length, and width directions. The interior of the housing 10 is hollow to form the installation cavity 11, and both ends of the housing 10 in the height direction are respectively provided with the installation opening 12 and the air outlet hole 13. The installation opening 12 is located at the lower end of the housing 10 and is communicated with the installation cavity 11 for installing the liquid cup 20 into the installation cavity 11. The air outlet hole 13 is located at the upper end of the housing 10, and the air outlet hole 13 communicates the installation cavity 11 with the outside of the housing 10. When the user inhales, the air flow flows from the installation cavity 11 into the air outlet hole 13 and then into the user's mouth from the air outlet hole 13.

[0056] As Figure 1 or Figure 2As shown, the liquid cup 20 is used to store the atomizing liquid, and the liquid cup 20 is installed in the installation cavity 11. An air flow channel 30 is formed at an interval between the outer wall of the liquid cup 20 and the inner wall of the installation cavity 11. One end of the air flow channel 30 communicates with the installation opening 12, and the other end communicates with the air outlet hole 13.

[0057] Specifically, in this embodiment, reference can be made to Figure 5 , the liquid cup 20 includes a cup body 25 and a cover body 26. The cup body 25 is provided with a liquid storage cavity 251 and an installation port 252 communicating with the liquid storage cavity 251. The liquid storage cavity 251 is used to store the atomizing liquid. The cover body 26 is covered at the installation port 252, and a sealing member 27 is also clamped between the outer peripheral wall of the cover body 26 and the inner peripheral wall of the liquid storage cavity 251, so as to seal the assembly gap between the cover body 26 and the cup body 25 and avoid liquid leakage. A liquid outlet channel also penetrates through the cover body 26, and a liquid absorbing member 28 is provided at the liquid outlet of the liquid outlet channel close to the installation opening 12. The atomizing liquid flows from the liquid storage cavity 251 into the liquid outlet channel and then flows from the liquid outlet channel to the liquid absorbing member 28. Reference can be made to Figure 9 , the liquid absorbing member 28 is used to abut against the heating element 50 on the atomizing assembly 300, so that the heating element 50 can heat and atomize the atomizing liquid on the liquid absorbing member 28.

[0058] After the atomizing liquid is atomized into aerosol, in order to enable the aerosol to flow to the air outlet hole 13 along with the air flow, in this embodiment, as Figure 1 shown, after the liquid cup 20 is installed in the installation cavity 11 of the housing 10, an air flow channel 30 is also formed at an interval between the outer wall of the liquid cup 20 and the inner wall of the installation cavity 11. One end of the air flow channel 30 communicates with the installation opening 12, and the other end communicates with the air outlet hole 13. After the atomizing cartridge 100 is assembled to the atomizing assembly 300, the installation opening 12 can be made to communicate with the atomizing channel 70 on the atomizing assembly 300. In this way, the air flow channel 30 can communicate with the atomizing channel 70 through the installation opening 12. The aerosol can flow into the air flow channel 30 along with the air flow, then flow along the air flow channel 30 to the air outlet hole 13, and finally flow out through the air outlet hole 13.

[0059] It should be noted that in order to form the air flow channel 30 at an interval between the outer wall of the liquid cup 20 and the inner wall of the installation cavity 11, the volume of the liquid cup 20 can be made smaller than the volume of the installation cavity 11. When the liquid cup 20 is installed in the installation cavity 11, the liquid cup 20 cannot fill the installation cavity 11 completely, but fills a part of the installation cavity 11, and the unfilled gap can form the air flow channel 30. It should be noted that the formed air flow channel 30 needs to communicate with the installation opening 12 and the air outlet hole 13, so as to ensure that the aerosol can flow to the air outlet hole 13 through the air flow channel 30 and flow out through the air outlet hole 13.

[0060] Alternatively, the overall volume of the liquid cup 20 is substantially adapted to the volume of the installation cavity 11. An air guide groove is recessed on the outer wall of the liquid cup 20 or the inner wall of the installation cavity 11. The air guide groove extends from the installation opening 12 to the air outlet hole 13, thereby forming an air flow channel 30. The air guide groove can extend linearly along the height direction of the liquid cup 20 or the housing 10, or can extend in a curved shape on the outer periphery of the liquid cup 20 or the inner periphery of the installation cavity 11, as long as the installation opening 12 and the air outlet hole 13 can be connected.

[0061] In summary, it can be understood that the air flow channel 30 in the atomization cartridge 100 of the present application is formed by the gap between the liquid cup 20 and the housing 10 after the liquid cup 20 is installed in the housing 10, without the need for additional forming or assembly of the airway structure. This makes the forming method of the air flow channel 30 very simple and convenient, simplifies the production process of the atomization cartridge 100, and effectively solves the technical problem that the forming process of the air flow channel 30 in the existing atomization cartridge 100 is relatively complex.

[0062] Optionally, in one embodiment, as Figure 1 or Figure 2 shown, the installation opening 12 and the air outlet hole 13 are respectively located at both ends in the height direction of the housing 10. The air flow channel 30 at least includes a first air duct 31 extending along the height direction of the housing 10. Specifically, there is at least one gap between the outer wall of the liquid cup 20 and the inner wall of the installation cavity 11, and this gap extends along the height direction of the housing 10 and forms the first air duct 31. It can be understood that since the installation opening 12 and the air outlet hole 13 are respectively located at both ends in the height direction of the housing 10, when the air flow channel 30 includes the first air duct 31 extending along the height direction of the housing 10, the flow path of the air flow can be reduced, enabling the air flow to flow from the installation opening 12 to the air outlet hole 13 faster.

[0063] It should be noted that the first air duct 31 can be provided with one or multiple. For example, optionally, in one embodiment, as Figure 6 shown, the outer wall of the liquid cup 20 includes a first outer wall 21 and multiple second outer walls 22. The first outer wall 21 and the multiple second outer walls 22 constitute the outer peripheral wall of the liquid cup. The outer peripheral wall of the liquid cup and the cup body top wall 23 constitute the outer wall of the liquid cup 20. Specifically, in this embodiment, the outer wall of the liquid cup 20 includes one first outer wall 21, three second outer walls 22, and one cup body top wall 23. As Figure 4 shown, the inner wall of the installation cavity 11 includes a first inner wall 111 and multiple second inner walls 112. The first inner wall 111 and the multiple second inner walls 112 constitute the inner peripheral wall of the installation cavity 11. The inner peripheral wall of the installation cavity 11 and the cavity top wall 113 constitute the inner wall of the installation cavity. Specifically, in this embodiment, the inner wall of the installation cavity includes one first inner wall 111, three second inner walls 112, and one cavity top wall 113.

[0064] Among them, please combine Figure 1 , Figure 4 , Figure 5 and Figure 6 , the first outer wall 21 and the first inner wall 111 are arranged opposite to each other and spaced apart to form a first air passage 31. A plurality of second outer walls 22 and a plurality of second inner walls 112 correspond one by one and are arranged in close contact. That is, in this embodiment, only one first air passage 31 is formed by spacing between the liquid cup 20 and the outer shell 10. In this way, the concentrated flow of air can be realized, which is convenient for controlling the flow direction of the air and can avoid the situation that the air flow is scattered and affects the taste.

[0065] It should be noted here that in order to make a plurality of second outer walls 22 and a plurality of second inner walls 112 correspond one by one and be in close contact, the liquid cup 20 can be press-fitted into the installation cavity 11. When assembling, the liquid cup 20 is inserted into the installation cavity 11 with force. Except for the first outer wall 21 and the first inner wall 111 being spaced apart, a plurality of second outer walls 22 and a plurality of second inner walls 112 are in close contact with each other. Alternatively, an adhesive can be provided between a plurality of second outer walls 22 and a plurality of second inner walls 112 so that a plurality of second outer walls 22 and a plurality of second inner walls 112 are bonded together.

[0066] Optionally, in one embodiment, as Figure 3 , Figure 4 and Figure 6 shown, the length direction of the outer shell 10 is parallel to the length direction of the liquid cup 20, and the height direction of the outer shell 10 is parallel to the height direction of the liquid cup 20. The first outer wall 21 extends along the height direction of the liquid cup 20 and is located on one side of the length direction of the liquid cup 20. The first inner wall 111 extends along the height direction of the outer shell 10 and is located on one side of the length direction of the outer shell 10. Since the first air passage 31 is formed by spacing between the first outer wall 21 and the first inner wall 111, the first air passage 31 is located on one side of the length direction of the outer shell 10 or the liquid cup 20. This is beneficial to reducing the width dimension of the outer shell 10 and the liquid cup 20, and further beneficial to the flat design of the atomization cartridge 100 (such as the flat design of the mouthpiece 15), which is convenient for the user to put it into the mouth for sucking.

[0067] Optionally, in one embodiment, as Figure 4 shown, the inner wall of the installation cavity 11 further includes a cavity top wall 113 opposite to the installation opening 12. The air outlet hole 13 penetrates through the cavity top wall 113, and the air outlet hole 13 is centrally arranged in the length direction of the outer shell 10. In this way, the air flow (i.e., the aerosol mixed gas) can flow into the oral cavity from the middle position of the user's mouth, ensuring that the smoke amount at each position in the oral cavity is more uniform, thereby improving the taste and avoiding the technical problem of uneven taste at each position in the oral cavity.

[0068] AsFigure 1 As shown, the outer wall of the liquid cup 20 further includes a cup top wall 23 spaced opposite to the top wall 113 of the cavity. A second air passage 32 is formed by the spacing between the cup top wall 23 and the top wall 113 of the cavity. The second air passage 32 extends along the length direction of the outer shell 10, and one end of the second air passage 32 communicates with the first air passage 31, and the other end communicates with the air outlet hole 13. The first air passage 31 and the second air passage 32 together constitute an air flow passage 30.

[0069] It can be understood that by forming the second air passage 32 with the cup top wall 23 and the top wall 113 of the cavity spaced apart, the second air passage 32 connects the first air passage 31 and the air outlet hole 13. It is possible to ensure that the air flow can flow from the middle position in the user's mouth into the oral cavity while the first air passage 31 is on one side in the length direction of the outer shell 10, that is, while realizing the flat design of the atomizing cartridge 100, and also ensuring the smoking taste.

[0070] Optionally, in one embodiment, as Figure 1 or Figure 5 shown, the first outer side wall 21 includes a connected first diversion section 211 and a second diversion section 212. The first diversion section 211 extends along the height direction of the outer shell 10. The second diversion section 212 is connected between the first diversion section 211 and the cup top wall 23, and the second diversion section 212 is inclined toward the side where the air outlet hole 13 is located relative to the first diversion section 211.

[0071] Specifically, in Figure 1 it, the lower end of the first diversion section 211 is located at the installation opening 12, the upper end is connected to the lower end of the second diversion section 212, and the upper end of the second diversion section 212 is connected to the cup top wall 23. And in the length direction of the outer shell 10, the air outlet hole 13 is located on the right side of the first diversion section 211. Therefore, the second diversion section 212 is inclined to the right relative to the first diversion section 211, so that the air flow can be guided to the air outlet hole 13, making the air flow flow from the first air passage 31 to the second air passage 32 and the air outlet hole 13 faster and more smoothly.

[0072] Optionally, in one embodiment, as Figure 1 or Figure 5 shown, a first arc-shaped diversion section 24 is further connected between the second diversion section 212 and the cup top wall 23. It can be understood that since the air flow needs to turn when flowing from the first air passage 31 into the second air passage 32, by providing the first arc-shaped diversion section 24 between the second diversion section 212 and the cup top wall 23, the turning of the air flow can be made smoother, improving the use experience.

[0073] Optionally, in one embodiment, as Figure 1 or Figure 4As shown, a second arc-shaped flow guiding section 114 is further connected between the first inner side wall 111 and the cavity top wall 113. Similarly, when the air flow flows along the first inner side wall 111 to the cavity top wall 113, the air flow needs to turn and flow towards the air outlet 13. Therefore, by arranging the second arc-shaped flow guiding section 114 between the first inner side wall 111 and the cavity top wall 113, the turning of the air flow can be further made smoother, improving the usability.

[0074] Optionally, in an embodiment, as Figure 4 shown, a positioning boss 14 also protrudes from the cavity top wall 113. The positioning boss 14 extends from the cavity top wall 113 towards the installation opening 12. And as Figure 1 shown, the positioning boss 14 abuts against the cup top wall 23, so that the positioning of the liquid cup 20 can be realized during the combined installation, avoiding the situation that the depth of the liquid cup 20 inserted into the installation cavity 11 is too large or too small, which may lead to the second air passage 32 being too large or too small.

[0075] It should be noted that the specific position of the positioning boss 14 can be flexibly designed according to needs, as long as it can realize the positioning of the liquid cup 20 and does not affect the air flow towards the air outlet 13.

[0076] For example, optionally, in an embodiment, as Figure 1 or Figure 4 shown, the positioning boss 14 is located on the side of the air outlet 13 away from the first inner side wall 111. In this way, before the air flow reaches the air outlet 13, the positioning boss 14 can be avoided from obstructing the air flow. And in this embodiment, the positioning boss 14 has a guiding side wall 141 facing the first inner side wall 111, and the guiding side wall 141 is smoothly connected to the inner wall of the air outlet 13. In this way, the air flow can be guided from the second air passage 32 into the air outlet 13. That is to say, the positioning boss 14 in this embodiment not only positions the liquid cup 20 but also guides the air flow, achieving the effect of multi-purpose use of one object.

[0077] Optionally, in an embodiment, as Figure 7 shown, the liquid cup 20 is press-fitted into the housing 10 in the width direction of the housing 10. Specifically, in the width direction of the housing 10, the width of the installation cavity 11 is adapted to the width of the liquid cup 20. During assembly, the liquid cup 20 can be forced into the installation cavity 11, so that both sides of the liquid cup 20 in the width direction are press-fitted into the installation cavity 11. It can be understood that this is not only convenient for the installation of the liquid cup 20 but also can ensure the stability of the liquid cup 20 after installation.

[0078] Optionally, in an embodiment, as Figure 4 shown, the air outlet 13 includes a diffusion section 131. Please also refer to Figure 2, one end of the diffusion section 131 communicates with the air flow channel 30, and the other end communicates with the outside of the housing 10. In the direction away from the liquid cup 20, the inner diameter of the diffusion section 131 gradually increases. Specifically, in this embodiment, the diffusion section 131 is in an inverted cone shape. The inner diameter of the end of the diffusion section 131 communicating with the air flow channel 30 is smaller, and the inner diameter of the end communicating with the outside of the liquid cup 20 is larger. In the direction away from the liquid cup 20, the inner diameter of the diffusion section 131 gradually increases. It can be understood that the diffusion section 131 with a gradually increasing inner diameter can cause the aerosol to spread before entering the user's mouth, and thus can fill the user's oral cavity faster, improving the use experience.

[0079] It should be noted here that the diffusion section 131 can be directly connected to the air flow channel 30, that is, the air outlet 13 only includes the diffusion section 131, and the entire air outlet 13 is in an inverted cone shape. In the direction away from the liquid cup 20, the inner diameter of the air outlet 13 gradually increases.

[0080] Or, optionally, in an embodiment, as Figure 4 shown, the air outlet 13 further includes a connecting section 132. Please refer to Figure 2 again. The diffusion section 131 is connected to the air flow channel 30 through the connecting section 132, and the connecting section 132 is cylindrical, that is, the inner diameter at each position in the connecting section 132 is set to be the same, which can prevent the aerosol from spreading prematurely in the air outlet 13.

[0081] Optionally, in an embodiment, the liquid cup 20 is provided with a liquid storage cavity 251 and a liquid outlet channel 912 communicating with the liquid storage cavity 251. A first seal 920 is provided in the liquid storage cavity 251. The first seal 920 includes a seal block 921 and an elastic arm 922. One end of the elastic arm 922 is fixedly arranged relative to the liquid cup 20, and the other end is connected to the seal block 921. The seal block 921 can move relative to the liquid cup 20.

[0082] Wherein, when at least part of the seal block 921 is located in the liquid outlet channel 912, the elastic arm 922 is in a deformed state and has an elastic restoring force for keeping the seal block 921 blocking the liquid outlet channel 912; when the seal block 921 is located outside the liquid outlet channel 912, the elastic arm 922 is in a deformed state and has an elastic restoring force for driving the seal block 921 to block the liquid outlet channel 912.

[0083] Specifically, in this embodiment, as Figures 10 to 12 shown, the liquid cup 20 includes a cup body 25 and a cup cover assembly 914. Among them, as Figure 12As shown, a liquid storage cavity 251 is provided inside the cup body 25, and an installation opening 252 communicating with the liquid storage cavity 251 is provided at the lower end of the cup body 25; the cup cover assembly 914 includes a cover body 26 and a second seal 27 sleeved on the cover body 26. The cover body 26 is fixed at the installation opening 252 of the cup body 25 in a snap - connection manner to cover the installation opening 252. The second seal 27 is at least partially clamped between the outer peripheral wall of the cover body 26 and the inner peripheral wall of the cup body 25, thereby sealing the assembly gap between the cover body 26 and the cup body 25 and preventing the atomized liquid from leaking out through the assembly gap between the cup body 25 and the cover body 26.

[0084] A liquid outlet channel 912 also penetrates through the cover body 26. As Figure 13 shown, Figure 13 For Figure 12 a partial structural schematic diagram of the liquid cup 20 in

[0085] Of course, in some other embodiments, the cup body 25 and the cover body 26 can be integrally formed. At this time, the opening for injecting the atomized liquid and installing the first seal 920 can be provided at the upper end of the liquid cup 20 (the upper and lower are referenced by the orientation indication in Figure 10 ).

[0086] As Figure 10 or Figure 11 shown, the first seal 920 is arranged inside the liquid storage cavity 251, and the first seal 920 includes a sealing block 921 and an elastic arm 922. The sealing block 921 can move relative to the liquid cup 20. One end of the elastic arm 922 is fixedly arranged relative to the liquid cup 20, and the other end is connected to the sealing block 921. Among them, as Figure 10 shown, when at least part of the sealing block 921 is located inside the liquid outlet channel 912, the elastic arm 922 is in a deformed state and has an elastic restoring force to keep the sealing block 921 blocking the liquid outlet channel 912. Reference can be made to Figure 18 , when the sealing block 921 is located outside the liquid outlet channel 912, the elastic arm 922 is in a deformed state and has a tendency to drive the sealing block 921 to block the liquid outlet channel 912.

[0087] Specifically, the outer shape of the sealing block 921 can be adapted to the liquid outlet channel 912. For example, in the structural scheme shown in Figure 14 , the liquid outlet channel 912 is a circular channel. Therefore, as Figure 15As shown, the overall shape of the sealing block 921 is also designed as a cylinder, which can better block the liquid outlet channel 912. In addition, the material of the sealing block 921 can be elastic rubber, which can not only seal the liquid outlet channel 912 well, but also has a relatively light weight, avoiding excessive weight of the liquid cup 20.

[0088] It should be noted that, it can be combined with Figure 10 and Figure 13 Understand that the sealing block 921 can block the liquid outlet channel 912 by blocking the inner liquid outlet 121 of the liquid outlet channel 912, or can also block the liquid outlet channel 912 by extending into the liquid outlet channel 912 (for example, when the liquid outlet channel 912 is conical, the sealing block 921 is blocked at the middle position of the liquid outlet channel 912), and can also block the liquid outlet channel 912 by blocking the outer liquid outlet 122 of the liquid outlet channel 912 (for example, when the liquid outlet channel 912 is conical, the sealing block 921 blocks at the outer liquid outlet 122).

[0089] As Figure 10 shown, one end of the elastic arm 922 is fixedly arranged relative to the liquid cup 20. Since the liquid cup 20 includes a cup body 25 and a cover body 26, one end of the elastic arm 922 can be directly or indirectly fixed on the cup body 25, or can also be directly or indirectly fixed on the cover body 26. And the other end of the elastic arm 922 is connected to the sealing block 921. In this embodiment, the elastic arm 922 and the sealing block 921 are integrally formed. Of course, in other embodiments, the elastic arm 922 can also be connected by means of clamping, bonding, tying, etc.

[0090] In this embodiment, when the sealing block 921 blocks the liquid outlet channel 912, the elastic arm 922 is also in a deformed state and maintains a tendency to drive the sealing block 921 to block the liquid outlet channel 912, which can make the sealing block 921 not easily separate from the liquid outlet channel 912 to open the liquid outlet channel 912, achieving a better sealing effect.

[0091] It should be noted that the number of the elastic arms 922 can be one or multiple. For example, when there is one elastic arm 922, in order to make the elastic arm 922 have sufficient elasticity, the elastic arm 922 can be a metal spring piece. One end of the metal spring piece is fixedly connected to the cup body 25 of the liquid cup 20, and the other end is fixed to the upper end of the sealing block 921 and presses the sealing block 921 against the inner liquid outlet 121 of the liquid outlet channel 912, so as to block the liquid outlet channel 912.

[0092] For another example, the elastic arms 922 can be provided in two, three, four, five, etc. A plurality of elastic arms 922 can be arranged at intervals in the circumferential direction of the sealing block 921, and each elastic arm 922 is connected to the sealing block 921 at one end and to the cup body 25 or the cover body 26 at the other end. This can increase the acting force on the sealing block 921, so that the sealing block 921 can block the liquid outlet channel 912 more tightly, improving the sealing effect. Further, the plurality of elastic arms 922 can be evenly spaced, so that the forces at various positions of the sealing block 921 are more uniform, and thus the liquid outlet channel 912 can be blocked more stably.

[0093] Further, in this embodiment, the sealing block 921 is further configured to be pushed away and located outside the liquid outlet channel 912, thereby opening the liquid outlet channel 912. At this time, the elastic arm 922 is also in a deformed state and has a tendency to drive the sealing block 921 to block the liquid outlet channel 912.

[0094] Specifically, since the liquid cup 20 of the present application is used on the atomization cartridge 100, and the atomization cartridge 100 needs to be installed on the atomization assembly 300, reference can be made to Figure 17 and Figure 18 , Figure 17 which is a structural cross-sectional view of an embodiment of the aerosol atomization cartridge 100 of the present application, Figure 18 which is a partial structural cross-sectional view of the aerosol generating device 400 of the present application. A push rod 80 can be provided on the atomization assembly 300. The push rod 80 extends along the axial direction of the liquid outlet channel 912. When the atomization cartridge 100 with the liquid cup 20 is installed on the atomization assembly 300, the push rod 80 extends into the liquid storage cavity 251 through the liquid outlet channel 912 and pushes the sealing block 921 to move, so that the sealing block 921 is separated from the liquid outlet channel 912 to open the liquid outlet channel 912. Then, the atomization liquid in the liquid storage cavity 251 can flow out through the liquid outlet channel 912 and flow onto the atomization assembly 300 to be atomized by the atomization assembly 300.

[0095] Because the elastic arm 922 still has a tendency to drive the sealing block 921 to block the liquid outlet channel 912, when the atomization cartridge 100 is removed from the atomization assembly 300, so that the sealing block 921 is no longer pushed by the push rod 80, the sealing block 921 will move back to the position blocking the liquid outlet channel 912 under the elastic force of the elastic arm 922, thereby preventing the atomization liquid in the liquid cup 20 from flowing out and leaking through the liquid outlet channel 912.

[0096] In summary, it can be understood that in the liquid cup 20 of the embodiment of the present application, by arranging a first seal 920 in the liquid storage cavity 251 of the liquid cup 20, the first seal 920 includes a sealing block 921 and an elastic arm 922. The sealing block 921 is arranged to block the liquid outlet channel 912, and the elastic arm 922 is in a deformed state and maintains a tendency to drive the sealing block 921 to block the liquid outlet channel 912. That is, the elastic arm 922 fixes the sealing block 921 at the position of blocking the liquid outlet channel 912. It is not easy for the sealing block 921 to overcome the elastic force of the elastic arm 922 to open the liquid outlet channel 912, thereby avoiding the atomized liquid from flowing out and leaking from the liquid outlet channel 912.

[0097] When in use, a push rod 80 can be preset on the atomization assembly 300. When the atomization cartridge 100 with the above liquid cup 20 is installed on the atomization assembly 300, the sealing block 921 can be pushed open by the push rod 80 extending into the liquid outlet channel 912 to open the liquid outlet channel 912, so that the atomized liquid in the liquid cup 20 can flow out from the liquid outlet channel 912 and be atomized by the atomization assembly 300.

[0098] Since the elastic arm 922 still maintains a tendency to drive the sealing block 921 to block the liquid outlet channel 912 after the sealing block 921 is pushed open, when the atomization cartridge 100 is removed from the atomization assembly 300, so that the sealing block 921 is no longer pressed by the push rod 8, the sealing block 921 will move back to the position of blocking the liquid outlet channel 912 under the elastic force of the elastic arm 922, thereby avoiding the atomized liquid in the liquid cup 20 from flowing out and leaking from the liquid outlet channel 912.

[0099] Optionally, in one embodiment, there are multiple elastic arms 922, and the multiple elastic arms 922 are arranged at intervals along the circumferential direction of the sealing block 921. Specifically, in Figure 15 there are two elastic arms 922, and the two elastic arms 922 are arranged opposite to each other along the diameter direction of the sealing block 921. Of course, in other embodiments, the number of elastic arms 922 can also be three, four, five, etc. The multiple elastic arms 922 are arranged at intervals along the circumferential direction of the sealing block 921, which can increase the acting force of the elastic arm 922 on the sealing block 921, so that the sealing block 921 can better and more stably block the liquid outlet channel 912 and improve the sealing effect.

[0100] It should be noted that when there are multiple elastic arms 922, the multiple elastic arms 922 can be respectively fixed to the liquid cup 20, or can be indirectly fixed to the liquid cup 20 through an intermediate member. For example, optionally, in one embodiment, as Figure 10 and Figure 11 shown, the first seal 920 further includes a fixing ring 923. One end of the elastic arm 922 is connected to the sealing block 921, and the other end is connected to the fixing ring 923, and the fixing ring 923 is fixedly connected to the liquid cup 20.

[0101] Specifically, in this embodiment, the sealing block 921, the plurality of elastic arms 922, and the fixing ring 923 are integrally formed. The fixing ring 923 surrounds the sealing block 921, and the elastic arms 922 are connected between the sealing block 921 and the fixing ring 923. The fixing ring 923 is fixedly connected to the liquid cup 20, so that one end of the elastic arm 922 is fixedly arranged relative to the liquid cup 20.

[0102] It can be understood that by providing the fixing ring 923, the plurality of elastic arms 922 are connected to the fixing ring 923, and the fixing ring 923 is fixedly connected to the liquid cup 20. In this way, it is not necessary to connect the plurality of elastic arms 922 to the liquid cup 20 one by one, simplifying the assembly process, thereby improving the assembly efficiency and reducing the production cost.

[0103] It should be noted that the fixing ring 923 can be fixedly connected to the liquid cup 20 by means of snap connection, bonding, screw connection, etc. For example, optionally, in one embodiment, as Figure 12 shown, a first engaging structure 9131 is provided on the inner wall of the liquid storage cavity 251. As Figure 15 shown, a second engaging structure 231 is provided on the fixing ring 923. Please refer to Figure 10 , the first engaging structure 9131 and the second engaging structure 231 are detachably engaged. It can be understood that the fixing ring 923 is detachably connected to the liquid cup 20 through the first engaging structure 9131 and the second engaging structure 231, which can not only achieve the stable connection between the fixing ring 923 and the liquid cup 20, but also facilitate the assembly and disassembly of the fixing ring 923, and further facilitate the replacement or repair of the first seal 920 during use.

[0104] It should be noted that one of the first engaging structure 9131 and the second engaging structure 231 can be a slot, and the other can be a convex. Or optionally, in one embodiment, as Figure 13 shown, the first engaging structure 9131 includes an adjacent first annular convex 1311 and a first annular slot 1312. As Figure 15 shown, the second engaging structure 231 includes an adjacent second annular convex 2311 and a second annular slot 2312; please refer to Figure 10 again, the first annular convex 1311 is inserted into the second annular slot 2312, and the second annular convex 2311 is inserted into the first annular slot 1312.

[0105] That is, the first engaging structure 9131 and the second engaging structure 231 are engaged by means of mutual insertion. It can be understood that this can make the engagement between the first engaging structure 9131 and the second engaging structure 231 more stable and reliable, avoiding the situation that the fixing ring 923 is driven to disengage from the liquid cup 20 when the elastic arm 922 is stressed, and ensuring the stable installation of the first seal 920.

[0106] In addition, it can be understood that if the length of the first annular convexity 1311 inserted into the second annular slot 2312 is too small, or the length of the second annular convexity 2311 inserted into the first annular slot 1312 is too small, the fixing ring 923 is relatively easily pulled by the elastic arm 922 and separated from the liquid cup 20. Therefore, in order to avoid the above problems, optionally, the length of the first annular convexity 1311 extending into the second annular slot 2312 and the length of the second annular convexity 2311 extending into the first annular slot 1312 are both greater than or equal to 1.5 mm, so as to avoid the situation that the fixing ring 923 is pulled and separated from the liquid cup 20 due to too small insertion depth.

[0107] Optionally, in one embodiment, as Figure 15 or Figure 16 shown, the fixing ring 923 includes a base ring body 232, a first ring body 233 and a second ring body 234. The first ring body 233 and the second ring body 234 are connected to the base ring body 232. The second ring body 234 surrounds the first ring body 233, and the first ring body 233 and the second ring body 234 are spaced apart to form the second annular slot 2312. The second ring body 234 constitutes the second annular convexity 2311, and one end of the elastic arm 922 is connected to the first ring body 233.

[0108] Please refer to Figure 10 、 Figure 13 and Figure 16 for understanding. When the elastic arm 922 is stretched and deformed to pull the fixing ring 923, the fixing ring 923 mainly overcomes the pulling force of the elastic arm 922 through the interaction between the second ring body 234 (i.e., the second annular convexity 2311) and the first annular convexity 1311, thereby avoiding the fixing ring 923 from loosening from the liquid cup 20. Therefore, it can be understood that if the width of the second ring body 234 is small, the engagement of the fixing ring 923 on the liquid cup 20 will be unstable and prone to loosening under the pulling of the elastic arm 922. Therefore, in this embodiment, in the width direction of the second annular slot 2312, the width of the second ring body 234 is greater than the width of the first ring body 233. It can be understood that by setting the width of the second ring body 234 to be larger, the second ring body 234 can have a greater clamping force in the first annular slot 1312, be able to better overcome the pulling force of the elastic arm 922, and make the fixing ring 923 be fixed on the liquid cup 20 more stably.

[0109] Optionally, in one embodiment, as Figure 12As shown, the liquid cup 20 includes a cup body 25 and a cup lid assembly 914. The cup body 25 has a liquid storage cavity 251 and an installation opening 252 communicating with the liquid storage cavity 251. The cup lid assembly 914 is covered at the installation opening 252, and a liquid outlet channel 912 penetrates through the cup lid assembly 914. Among them, the sealing block 921 abuts against the cup lid assembly 914 and blocks the liquid outlet channel 912. Please also refer to Figure 10 and Figure 16 , the cup lid assembly 914 also abuts against the side of the base ring body 232 away from the first annular card slot 1312 to limit the second ring body 234 from disengaging from the first annular card slot 1312.

[0110] Specifically, in this embodiment, please refer to Figure 10 、 Figure 13 and Figure 16 for understanding. If the pulling force of the elastic arm 922 is large enough to pull the fixing ring 923 and disengage it from the cup body 25, the second ring body 234 (i.e., the second annular convex 2311) on the fixing ring 923 will move downward first and disengage from the first annular card slot 1312. Therefore, as long as the downward movement of the second ring body 234 can be restricted, the disengagement of the fixing ring 923 from the cup body 25 can be restricted. So in this embodiment, by making the cup lid assembly 914 also abut against the side of the base ring body 232 away from the first annular card slot 1312, that is, the cup lid assembly 914 abuts against the lower side of the base ring body 232, the second ring body 234 can be restricted from disengaging from the first annular card slot 1312, and further the fixing ring 923 can be stably engaged with the cup body 25.

[0111] Among them, it should be noted that the cup lid assembly 914 may only include the lid body 26, or may include the lid body 26 and other components. For example, optionally, in an embodiment, as shown in Figure 12 or Figure 13 , the cup lid assembly 914 includes the lid body 26 and the second sealing member 27. The lid body 26 is snap-fitted and installed on the card hole 133 of the cup body 25 through the snap 1411, and a liquid outlet channel 912 penetrates through the lid body 26. The second sealing member 27 is clamped between the outer peripheral wall of the lid body 26 and the inner peripheral wall of the cup body 25 to seal the gap between the lid body 26 and the cup body 25 and prevent the atomized liquid from leaking. In addition, in this embodiment, reference can be made to Figure 10 , the second sealing member 27 also abuts against the base ring body 232, so that there is also a certain sealing effect between the fixing ring 923 and the second sealing member 27, further improving the sealing performance of the entire liquid cup 20.

[0112] In addition, in order to ensure that after the sealing block 921 opens the liquid outlet channel 912, the atomized liquid in the liquid storage cavity 251 can continuously flow from the liquid storage cavity 251 into the liquid outlet channel 912 and flow out from the liquid outlet channel 912, as shown in Figure 13 andFigure 14 As shown, an air pressure balance channel 1412 is further provided on the cover body 26. One end of the air pressure balance channel 1412 is located at the top of the cover body 26 and communicates with the liquid storage cavity 251, and the other end is located at the bottom of the cover body 26 and communicates with the outside of the liquid cup 20. In order to prevent the atomized liquid from flowing out through the air pressure balance channel 1412, the second seal 27 also covers one end of the air pressure balance channel communicating with the liquid storage cavity 251, so that the air pressure balance channel 1412 can be sealed when the air pressures inside and outside the liquid cup 20 are balanced, and the atomized liquid is prevented from flowing out through the air pressure balance channel 1412.

[0113] As the atomized liquid continuously flows out, the air pressure in the liquid storage cavity 251 decreases and is lower than the air pressure outside the liquid cup 20. At this time, the second seal 27 opens one end of the air pressure balance channel 1412 communicating with the liquid storage tank 9213 under the action of the internal and external pressure difference, so that the air outside the liquid cup 20 can flow into the liquid storage cavity 251 through the air pressure balance channel, making the air pressures inside and outside the liquid cup 20 balanced, and thus ensuring that the atomized liquid can continuously flow out from the liquid outlet channel 912.

[0114] Optionally, in an embodiment, as Figure 16 shown, the elastic arm 922 is also connected to the base ring body 232. Specifically, in this embodiment, since the width of the first ring body 233 is small, in order to prevent breakage between the first ring body 233 and the base ring body 232, which may lead to the disconnection of the elastic arm 922 from the fixed ring 923, in this embodiment, the elastic arm 922 is also connected to the base ring body 232, that is, the elastic arm 922 is connected to both the first ring body 233 and the base ring body 232, which can improve the connection stability between the elastic arm 922 and the fixed ring 923 and prevent the disconnection between the elastic arm 922 and the fixed ring 923.

[0115] Optionally, in an embodiment, as Figure 15 shown, the fixed ring 923 has opposite length and width directions; on the length direction of the fixed ring 923, elastic arms 922 are respectively connected to both sides of the sealing block 921, and / or, on the width direction of the fixed ring 923, elastic arms 922 are respectively connected to both sides of the sealing block 921.

[0116] Specifically, in this embodiment, the overall shape of the fixed ring 923 is approximately rectangular ring-shaped, so the fixed ring 923 has opposite length and width directions, and the size of the fixed ring 923 in its length direction is greater than its size in the width direction. And in this embodiment, there are two elastic arms 922, which can not only ensure that the elastic arms 922 have sufficient acting force on the sealing block 921, but also make the structure of the first seal 920 relatively simple and easy to produce.

[0117] Regarding the positions of the two elastic arms 922, the two elastic arms 922 can be located on opposite sides of the sealing block 921 along the length direction of the fixed ring 923. In this way, the length of the elastic arms 922 can be relatively long, so as to reduce the thrust required to push open the sealing block 921, making it easier and more convenient to install the atomization cartridge 100 on the atomization assembly 300.

[0118] Alternatively, the two elastic arms 922 can also be located on opposite sides of the sealing block 921 along the width direction of the fixed ring 923. In this way, the length of the elastic arms 922 can be relatively short, thereby reducing the occupied space of the first seal 920 in the liquid storage cavity 251, enabling the liquid cup 20 to store more atomization liquid.

[0119] Optionally, in an embodiment, as Figure 16 shown, the sealing block 921 has a sealing end 9211 at one end in its axial direction. As Figure 13 shown, the liquid outlet channel 912 has an inner liquid outlet 121 communicating with the liquid storage cavity 251. The inner liquid outlet 121 is provided with an inclined sealing surface 1211, and the inclined sealing surface 1211 extends along the circumferential direction of the inner liquid outlet 121. As Figure 10 shown, the sealing end 9211 abuts against the inclined sealing surface 1211.

[0120] Specifically, in this embodiment, the lower end of the sealing block 921 is the sealing end 9211, and the sealing end 9211 abuts against the inclined sealing surface 1211 at the inner liquid outlet 121. It can be understood that by providing the inclined sealing surface 1211 at the inner liquid outlet 121, the circumferential side of the sealing end 9211 can be in close contact with the inclined sealing surface 1211, thereby better sealing the liquid outlet channel 912 and avoiding the leakage of atomization liquid due to the existence of gaps.

[0121] Optionally, in an embodiment, as Figure 16 shown, the sealing end 9211 is provided with an arc-shaped sealing surface 2111, and the arc-shaped sealing surface 2111 extends along the circumferential direction of the sealing block 921. As Figure 10 shown, the arc-shaped sealing surface 2111 abuts against the inclined sealing surface 1211. Specifically, in this embodiment, the arc-shaped sealing surface 2111 is formed by chamfering the periphery of the sealing end 9211. In this way, not only can the sealing end 9211 be in close contact with the inclined sealing surface 1211, but also when the sealing block 921 is pushed and moved by the push rod 80, the probability of the sealing block 921 getting stuck in the inner liquid outlet 121 can be reduced, making the opening of the liquid outlet channel 912 smoother.

[0122] Optionally, in an embodiment, as Figure 16As shown, a positioning groove 9212 is provided on the end face of the sealing block 921 facing the liquid outlet channel 912. The positioning groove 9212 is used for the push rod 80 to extend into and push open the sealing block 921. Specifically, in this embodiment, the size and shape of the positioning groove 9212 are adaptively designed to match the push rod 80 for pushing open the sealing block 921. For example, when the push rod 80 is a round rod, the positioning groove 9212 is also designed as a round groove, and the inner diameter of the positioning groove 9212 is slightly larger than the outer diameter of the push rod 80, so that the push rod 80 can just penetrate into the positioning groove 9212. It can be understood that by setting the positioning groove 9212 to position the push rod 80, it is possible to avoid a large relative sliding between the push rod 80 and the sealing block 921 during the process of pushing the sealing block 921, ensuring that the push rod 80 can stably push open the sealing block 921.

[0123] Optionally, in one embodiment, as Figure 15 or Figure 16 shown, a liquid storage groove 9213 is provided on the end face of the sealing block 921 facing away from the liquid outlet channel 912. The liquid storage groove 9213 is used for storing the atomized liquid. Specifically, in this embodiment, the liquid storage groove 9213 can not only reduce the occupied space of the sealing block 921 in the liquid storage cavity 251, so that the liquid cup 20 can store more atomized liquid, but also reduce the weight of the sealing block 921, making the entire liquid cup 20 lighter.

[0124] It should be noted here that since the entire aerosol generating device 400 is in a nearly horizontal state when the user uses the aerosol generating device 400, the atomized liquid in the liquid storage groove 9213 can flow out and reach the liquid outlet channel 912. Of course, in order to prevent the atomized liquid from remaining in the liquid storage groove 9213, liquid outlet small holes can be provided on the side wall of the liquid storage groove 9213, so that the atomized liquid in the liquid storage groove 9213 can flow out and reach the liquid outlet channel 912.

[0125] Optionally, in one embodiment, as Figure 13 shown, the liquid outlet channel 912 has an outer liquid outlet 122. The outer liquid outlet 122 is communicated with the outside of the liquid cup 20, and an installation groove 1221 is provided at the outer liquid outlet 122. Please refer to Figure 10 again. An absorbent member 28 is installed in the installation groove 1221. The absorbent member 28 can be absorbent cotton, absorbent ceramic, etc. The absorbent member 28 is used for adsorbing the atomized liquid. When the atomization cartridge 100 is installed on the atomization assembly 300, the absorbent member 28 abuts against the heating element 50 on the atomization assembly 300, so that the heating element 50 can heat the atomized liquid on the absorbent member 28 to atomize the atomized liquid into aerosol. And in this embodiment, the absorbent member 28 is provided with a through hole 281 communicated with the liquid outlet channel 912. The through hole 281 is used for the push rod 80 to extend into and push open the sealing block 921, which facilitates the push rod 80 to pass through the through hole 281 and the liquid outlet channel 912, and then push open the sealing block 921 to open the liquid outlet channel 912.

[0126] Alternatively, optionally, in another embodiment, the liquid cup 20 is provided with a liquid storage cavity 251 and a liquid outlet channel 912. The liquid outlet channel 912 has opposite inner liquid outlet 121 and outer liquid outlet 122. The inner liquid outlet 121 communicates with the liquid storage cavity 251, and the outer liquid outlet 122 communicates with the outside of the liquid cup 20. A liquid absorbing member 28 is further provided at the outer liquid outlet 122, and the liquid absorbing member 28 is used for adsorbing the atomized liquid.

[0127] Specifically, in this embodiment, no first sealing member 920 is provided in the liquid storage cavity 251 of the liquid cup 20. At this time, a liquid absorbing member 28 is provided at the outer liquid outlet 122 of the liquid outlet channel 912. The liquid absorbing member 28 can be absorbent cotton, absorbent ceramic, etc. The liquid absorbing member 28 can absorb the atomized liquid from the liquid outlet channel 912, and the liquid absorbing member 28 can lock the atomized liquid, so as to avoid the leakage of the atomized liquid from the liquid outlet channel 912.

[0128] According to the second aspect of the present application, as Figure 8 and Figure 9 shown, an aerosol generating device 400 is provided, which includes a battery assembly 200, an atomizing assembly 300 and the atomizing cartridge 100 of any one of the above embodiments. The atomizing assembly 300 is mounted on the battery assembly 200, and the atomizing assembly 300 is provided with an atomizing channel 70. The atomizing cartridge 100 is mounted on the atomizing assembly 300, and the air flow channel 30 communicates with the atomizing channel 70.

[0129] Specifically, as Figure 9 shown, the battery assembly 200 mainly includes a battery 40 and a conductive terminal 41 electrically connected to the battery 40. The atomizing assembly 300 mainly includes a heating element 50 and an electrode member 60. One end of the electrode member 60 is electrically connected to the heating element 50. When the atomizing assembly 300 is mounted on the battery assembly 200, the electrode member 60 is also in electrical contact with the conductive terminal 41, so that the battery 40 can supply power to the electrode member 60, and the electrode member 60 then transfers electrical energy to the heating element 50.

[0130] The atomizing assembly 300 is further provided with an atomizing channel 70. The heating element 50 is located in the atomizing channel 70, or the heating element 50 is located on one side of the atomizing channel 70. When the atomizing cartridge 100 is mounted on the atomizing assembly 300, the mounting opening 12 of the housing 10 communicates with the atomizing channel 70, and thus the air flow channel 30 can communicate with the atomizing channel 70 through the mounting opening 12. In addition, the atomizing cartridge 100 can also be provided with a liquid absorbing member 28, and the liquid absorbing member 28 is used for adsorbing the atomized liquid in the liquid cup 20. When the atomizing cartridge 100 is mounted on the atomizing assembly 300, the liquid absorbing member 28 abuts against the heating element 50 so that the heating element 50 can atomize the atomized liquid when it is energized and heated.

[0131] It can be combined with Figure 8 andFigure 9 When the heating element 50 generates heat and atomizes the atomized liquid on the liquid absorption member 28, the aerosol generated in the atomization channel 70 can flow into the air flow channel 30 along with the air flow, then flow along the air flow channel 30 to the air outlet 13, and finally flow out through the air outlet 13.

[0132] Of course, the battery assembly 200 may further include components such as a circuit board and a microphone, and the atomization assembly 300 may further include components such as a bracket, a seal 27, and a support ceramic. Specifically, it can be designed according to the relevant prior art.

[0133] It can be understood that since the aerosol generating device 400 includes the atomization cartridge 100 of any one of the above embodiments, the aerosol generating device 400 has all the beneficial effects of the above atomization cartridge 10, and the details are not described herein again in the present disclosure.
