Detailed implementation manners

[0134] Next, the technical solutions in the embodiments of the present application will be clearly and completely described 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.

[0135] First of all, the existing aerosol generating device mainly includes an atomization cartridge and an atomization host. The atomization host is usually composed of a battery assembly and an atomization assembly. Among them, the battery assembly is used to provide electrical energy for the atomization assembly, the atomization cartridge is used to provide atomization liquid for the atomization assembly, and the atomization assembly converts electrical energy into heat energy, and then atomizes the atomization liquid into aerosol for the user to consume.

[0136] However, in the related art, the atomization assembly and the battery assembly in the atomization host are fixed as a whole. When one of the atomization assembly and the battery assembly is damaged or scrapped, the other will be discarded together, resulting in a relatively high use cost of the aerosol generating device.

[0137] To solve the above technical problems, according to the first aspect of the present application, as Figure 1 shown, an atomization host 400 is provided. The atomization host 400 mainly includes an atomization assembly 100 and a battery assembly 200.

[0138] Among them, as Figure 1 shown, the atomization assembly 100 includes a mounting shell 81 and an atomizer 810. The atomizer 810 is mounted on the mounting shell 81, and the atomizer 810 is used to atomize the atomization liquid. The atomizer 810 is also provided with an atomization electrode 862. Specifically, in this embodiment, the mounting shell 81 is a hollow column, the atomizer 810 is mounted in the mounting shell 81, and the atomizer 810 is used to convert electrical energy into heat energy to heat the atomization liquid so that the atomization liquid is atomized. Therefore, the atomizer 810 at least includes a heating element 82 and an atomization electrode 862. The heating element 82 can be made of a metal material, such as iron wire, copper mesh, etc. The atomization electrode 862 can also be made of a metal material such as iron or copper, and the atomization electrode 862 is electrically connected to the heating element 82, so that the heating element 82 can be connected to the circuit. When the heating element 82 is powered on, it can convert electrical energy into heat energy, and then heat and atomize the atomization liquid.

[0139] In addition, as Figure 4As shown, the upper and lower ends of the installation shell 81 are also open, so as to facilitate the loading of the atomization cartridge 300 and the battery assembly 200 and their respective connections to the atomizer 810. For the length of the installation shell 81 in the up and down direction, it can be flexibly set according to needs. For example, in one embodiment, when the installation shell 81 is also required to accommodate the atomization cartridge 300 and the battery assembly 200, the length of the installation shell 81 can be set longer to form accommodation cavities (i.e., the first cavity 811 and the second cavity 812) on the upper and lower sides of the atomizer 810 respectively, and the atomization cartridge 300 and the battery assembly 200 are respectively partially accommodated in the two cavities. Or, in some other embodiments, the length of the installation shell 81 in the up and down direction is adapted to the atomizer 810, and thus it is only used to accommodate the atomizer 810.

[0140] As Figure 1 shown, in this embodiment, the battery assembly 200 includes an installation frame 71, a battery body 72, and a power supply electrode 63. The installation frame 71 is detachably connected to the installation shell 81. The battery body 72 is installed on the installation frame 71, and a power supply electrode 63 is connected to the battery body 72. The power supply electrode 63 is detachably in electrical contact with the atomization electrode 862. Specifically, the installation frame 71 is a base component in the battery assembly 200 for installing components such as the battery body 72, the control board 74, and the airflow induction switch 75 (also known as the microphone head). Therefore, the installation frame 71 can be a plastic part, which can make the battery assembly 200 lighter in weight and lower in cost. The type of the battery body 72 is not limited and can be a lithium battery, a nickel-metal hydride battery, etc. And the battery body 72 can be installed on the installation frame 71 in a non-detachable manner or in a detachable manner.

[0141] A power supply electrode 63 is also connected to the battery body 72. There are two power supply electrodes 63, one of which is connected to the positive electrode and the other is connected to the negative electrode, so as to form an electrical conduction loop with the atomization electrode 862 and the heating element 82, and thus provide electrical energy for the atomizer 810.

[0142] Crucially, in this embodiment, the installation frame 71 is detachably connected to the installation shell 81, and the power supply electrode 63 is detachably in electrical contact with the atomization electrode 862. Specifically, the installation frame 71 and the installation shell 81 can be detachably connected by means of screw connection (i.e., internal threads and external threads are respectively provided on the installation frame 71 and the installation shell 81), screw connection, snap connection, magnetic attraction connection, etc. And after the installation frame 71 and the installation shell 81 are connected, a detachable electrical contact is formed between the power supply electrode 63 and the atomization electrode 862, which can not only meet the need for the battery body 72 to supply power to the atomizer 810, but also facilitate the separation of the power supply electrode 63 and the atomization electrode 862 when disassembly is required.

[0143] In summary, it can be understood that in the atomizing main unit 400 according to the embodiment of the present application, by detachably connecting the mounting shell 81 in the atomizing component 100 and the mounting bracket 71 in the battery component 200, and detachably electrically contacting the atomizing electrode 862 on the atomizer 810 and the power supply electrode 63 on the battery body 72, after the atomizing component 100 and the battery component 200 are assembled into the atomizing main unit 400, power supply from the battery body 72 to the atomizer 810 can be realized, and when one of the atomizing component 100 and the battery component 200 needs to be replaced, the atomizing component 100 and the battery component 200 can be disassembled and replaced, instead of replacing both the atomizing component 100 and the battery component 200 together, thus reducing the usage cost.

[0144] Optionally, in one embodiment, one of the mounting shell 81 and the mounting bracket 71 is press-fitted into the other. Specifically, as Figure 4 shown, an installation cavity 818 is formed in the mounting shell 81. First openings 512 and second openings 513 are respectively formed at two ends of the installation cavity 818. The atomizer 810 is installed in the installation cavity 818, and the atomizer 810 divides the installation cavity 818 into a first cavity 811 and a second cavity 812. The first cavity 811 communicates with the first opening 512, and the second cavity 812 communicates with the second opening 513. Reference can be made to Figure 1 , the mounting bracket 71 with the battery body 72 is inserted into the second cavity 812 from the second opening 513, and the mounting bracket 71 is press-fitted into the second cavity 812, that is, the mounting bracket 71 is press-fitted into the mounting shell 81.

[0145] It can be understood that in this embodiment, by press-fitting the mounting bracket 71 into the mounting shell 81, during assembly, it is only necessary to forcefully insert the mounting bracket 71 into the mounting shell 81, and during disassembly, it is only necessary to forcefully pull the mounting bracket 71 out of the mounting shell 81, so the disassembly and assembly are very simple and convenient.

[0146] Of course, in some other embodiments, it is also possible to press-fit the mounting shell 81 into the mounting bracket 71. For example, the mounting bracket 71 is provided with a cavity for the mounting shell 81 to be inserted and installed, and the mounting shell 81 is press-fitted into the cavity formed on the mounting bracket 71.

[0147] In addition, it should be noted that one of the mounting shell 81 and the mounting bracket 71 may be provided with a plugging protrusion, and the other may be provided with a plugging groove, and the plugging protrusion is press-fitted into the plugging groove. For example, a plugging protrusion is provided on the end face of the mounting shell 81 facing the mounting bracket 71, and a corresponding plugging groove is provided on the end face of the mounting bracket 71 facing the mounting shell 81. The mounting shell 81 is press-fitted into the plugging groove on the mounting bracket 71 through the plugging protrusion, so that press-fitting between the mounting shell 81 and the mounting bracket 71 can also be realized.

[0148] Optionally, in one embodiment, at least one of the atomizing electrode 862 and the power supply electrode 63 is a conductive elastic sheet, and the conductive elastic sheet is squeezed into a deformed state. Specifically, as Figure 1 shown, the atomizing electrode 862 is an electrode column, and the power supply electrode 63 is a conductive elastic sheet. After the atomizing assembly 100 and the battery assembly 200 are assembled, the atomizing electrode 862 and the power supply electrode 63 are in contact with each other, and the power supply electrode 63 is squeezed by the atomizing electrode 862 into a deformed state, so as to ensure stable contact between the atomizing electrode 862 and the power supply electrode 63 and avoid the problem of poor contact between the atomizing electrode 862 and the power supply electrode 63.

[0149] Alternatively, it can also be that the atomizing electrode 862 is a conductive elastic sheet and the power supply electrode 63 is an electrode column. After the atomizing assembly 100 and the battery assembly 200 are assembled, the atomizing electrode 862 and the power supply electrode 63 are in contact with each other, and the atomizing electrode 862 is squeezed by the power supply electrode 63 into a deformed state.

[0150] Or, it can also be that both the atomizing electrode 862 and the power supply electrode 63 are conductive elastic sheets. After the atomizing assembly 100 and the battery assembly 200 are assembled, the atomizing electrode 862 and the power supply electrode 63 are in contact with each other, and the power supply electrode 63 and the atomizing electrode 862 are squeezed against each other and both are in a deformed state.

[0151] In some embodiments, as Figures 1 to 4 shown, the atomizing assembly 100 includes a mounting shell 81, a heating element 82, a sealing seat 83, and a support member 84.

[0152] The mounting shell 81 is arranged in a rod shape and has a hollow inner cavity. Both the top end and the bottom end of the mounting shell 81 are arranged as open ends. The inner cavity of the mounting shell 81 is divided into a first cavity 811 and a second cavity 812. The inside of the first cavity 811 is configured to be able to accommodate at least a part of the atomizing cartridge 300, and the atomizing cartridge 300 is arranged to be removably received in the first cavity 811. The inside of the second cavity 812 is configured to be able to accommodate at least a part of the battery assembly 200, and the battery assembly 200 is arranged to be removably received in the second cavity 812.

[0153] The sealing seat 83 is made of flexible silicone material, and the sealing seat 83 is arranged inside the mounting shell 81 and is used to separate the first cavity 811 and the second cavity 812. As Figure 5 shown, the sealing seat 83 includes a main body portion 831 and a clamping portion 832, and the clamping portion 832 protrudes towards the direction close to the first cavity 811 relative to the main body portion 831. The main body portion 831 is sealingly connected to the mounting shell 81, and a plurality of sealing ribs are further arranged on the outer surface of the main body portion 831, so as to effectively prevent the leakage of the atomizing liquid.

[0154] As Figure 4As shown, the support member 84 is made of a hard material, and the support member 84 is connected to the sealing seat 83. Among them, the clamping portion 832 is located on the side of the support member 84 away from the main body portion 831.

[0155] The heating element 82 is disposed between the clamping portion 832 and the support member 84, and the heating element 82 is disposed closer to the first cavity 811 relative to the support member 84.

[0156] By clamping the heating element 82 between the support member 84 and the clamping portion 832 of the sealing seat 83, the fixing of the heating element 82 is achieved, and the heating element 82 is disposed closer to the first cavity 811 relative to the support member 84. The atomizing liquid provided by the atomizing cartridge 300 is directly provided to the heating element 82 for atomization. And the above atomizing assembly 100 does not include a liquid guiding element. Therefore, even if different flavored atomizing cartridges 300 are replaced, the atomizing liquid provided by the atomizing cartridge 300 is directly provided to the heating element 82, thus not affecting the taste of the aerosol generated by the atomizing of the atomizing assembly 100.

[0157] In some embodiments, as Figures 5 to 7 shown, the sealing seat 83 includes a first clamping arm 8324 and a second clamping arm 8325 arranged at intervals. The sealing seat 83 further includes a receiving groove 8323. The support member 84 is disposed in the receiving groove 8323, and the receiving groove 8323 is located between the first clamping arm 8324 and the second clamping arm 8325. Among them, the clamping portion 832 includes a first clamping portion 8321 and a second clamping portion 8322. The first clamping arm 8324 is connected between the first clamping portion 8321 and the main body portion 831, and the second clamping arm 8325 is connected between the second clamping portion 8322 and the main body portion 831.

[0158] It should be noted that the first clamping portion 8321 and the first clamping arm 8324 can be integrally formed, and the second clamping portion 8322 and the second clamping arm 8325 can be integrally formed. The first clamping portion 8321 and the second clamping portion 8322 are arranged to be the parts located on the support member 84 and used for clamping the heating element 82. The first clamping arm 8324 is arranged to extend longitudinally along the mounting shell 81 and used for connecting the first clamping portion 8321 and the main body portion 831. The second clamping arm 8325 is arranged to extend longitudinally along the mounting shell 81 and used for connecting the second clamping portion 8322 and the main body portion 831.

[0159] As Figure 6 or Figure 7As shown, the first clamping arm 8324 is provided with a first positioning hole 8331, and the second clamping arm 8325 is provided with a second positioning hole 8332. In a specific embodiment, the first positioning hole 8331 and the second positioning hole 8332 are respectively arranged as blind hole structures, and one side of the first positioning hole 8331 and the second positioning hole 8332 is open and communicates with the receiving groove 8323. The first clamping arm 8324 and the second clamping arm 8325 are arranged as an asymmetric structure. One end of the first clamping arm 8324 extends to the front end of the main body portion 831, and the other end of the second clamping arm 8325 extends to the rear end of the main body portion 831. A circumferentially extending flange structure is further arranged between the first clamping arm 8324 and the second clamping arm 8325. The first clamping arm 8324, the second clamping arm 8325 and the flange structure jointly enclose to form the receiving groove 8323.

[0160] As Figure 9 shown, the support member 84 includes a base portion 841, a first boss portion 8421 and a second boss portion 8422. The first boss portion 8421 and the second boss portion 8422 protrude relative to the base portion 841 towards the direction close to the first cavity 811, and the first boss portion 8421 and the second boss portion 8422 are respectively located on both sides of the base portion 841. Please refer to Figure 6 , a part of the first boss portion 8421 is arranged in the first positioning hole 8331, a part of the second boss portion 8422 is arranged in the second positioning hole 8332, and the base portion 841 is held and received in the receiving groove 8323.

[0161] As Figure 5 and Figure 8 shown, the heating element 82 includes a heating portion 821, a first conductive portion 8221 and a second conductive portion 8222. The heating portion 821 is electrically connected to the battery assembly 200 through the first conductive portion 8221 and the second conductive portion 8222. The heating portion 821 is used to generate high-temperature heat after the first conductive portion 8221 and the second conductive portion 8222 are energized, so as to atomize the atomized liquid into aerosol. The first conductive portion 8221 and the second conductive portion 8222 are respectively connected to both sides of the heating portion 821. Among them, as Figure 6 shown, a part of the heating portion 821 is respectively located on the first boss portion 8421 and the second boss portion 8422. The first conductive portion 8221 is located in the first positioning hole 8331 and is clamped between the first boss portion 8421 and the first clamping portion 8321. The second conductive portion 8222 is located in the second positioning hole 8332 and is clamped between the second boss portion 8422 and the second clamping portion 8322.

[0162] By clamping the first conductive part 8221 and the second conductive part 8222 at both ends of the heating part 821, a part of the heating part 821 is supported on the first boss part 8421 and the second boss part 8422, so that the heating element 82 can be stably arranged between the support part 84 and the clamping part 832. Further, the main body part of the heating part 821 is suspended between the first boss part 8421 and the second boss part 8422, and the spaced space between the heating part 821 and the base part 841 of the support part 84 forms an atomization channel 883, which is beneficial to the sufficient atomization of the atomization liquid.

[0163] In some embodiments, as Figure 4 and Figure 10 shown, the atomization assembly 100 further includes a base 85, and the base 85 is arranged in the mounting shell 81 and is used to support the sealing seat 83. The base 85 is made of a hard plastic material, and the main body part 831 of the sealing seat 83 is arranged at the connection part between the mounting shell 81 and the base 85, so as to seal the connection gap between the mounting shell 81 and the base 85. In a specific implementation, as Figure 4 shown, the base 85 is fixedly connected to the mounting shell 81 through a pin 851. At least two first pin positioning holes 813 are arranged on the mounting shell 81, and at least two second pin positioning holes 852 are arranged on the base 85. The first pin positioning holes 813 and the second pin positioning holes 852 are arranged opposite to each other, and the pin 851 sequentially passes through the first pin positioning hole 813 and the second pin positioning hole 852, so as to fix the base 85 on the mounting shell 81.

[0164] In some embodiments, as Figures 1 to 4 shown, the atomization assembly 100 further includes a push rod 86. The atomization cartridge 300 is removably received in the first cavity 811. As Figure 2 or Figure 3 shown, a first seal 920 for sealing its liquid outlet channel 912 is arranged inside the atomization cartridge 300. The push rod 86 is used to push open the first seal 920, so that the atomization liquid inside the atomization cartridge 300 can flow out through the liquid outlet channel 912 and flow onto the heating element 82.

[0165] By arranging the push rod 86 on the atomization assembly 100, during the process of the cooperation connection between the atomization cartridge 300 and the atomization assembly 100, the push rod 86 can push open the first seal 920 arranged on the atomization cartridge 300, so that the atomization liquid inside the atomization cartridge 300 can flow out and flow onto the heating element 82.

[0166] As Figure 4As shown, the push rod 86 is made of a hard plastic material or a metal material to form a rod-shaped body. The push rod 86 sequentially passes through the base 85, the sealing seat 83, the support member 84, and the heating element 82, and protrudes relative to the top surface where the clamping portion 832 of the sealing seat 83 is located. In a specific embodiment, as Figure 10 shown, a first through hole 853 is provided on the base 85, as Figure 7 shown, a push rod sealing hole 834 is provided on the sealing seat 83, as Figure 8 shown, a through hole 8212 is provided on the heating portion 821 of the heating element 82. Please refer to Figure 4 , the first through hole 853, the push rod sealing hole 834, the second through hole 845, and the through hole 8212 are longitudinally connected along the installation shell 81, facilitating the push rod 86 to sequentially pass through the first through hole 853, the push rod sealing hole 834, and the through hole 8212. Among them, as Figure 6 and Figure 7 shown, one end of the main body portion 831 is provided with a push rod sealing column 8341, and the push rod sealing hole 834 penetrates through the main body portion 831 and the push rod sealing column 8341. As Figure 9 shown, a second through hole 845 is provided on the support member 84, and the push rod sealing column 8341 is received in the second through hole 845 of the support member 84. An interference fit is formed between the push rod 86 and the push rod sealing column 8341, thereby effectively preventing the atomized liquid from leaking through the connection gap between the push rod 86 and the sealing seat 83. Moreover, the aperture of the through hole 8212 of the heating element 82 is larger than the outer diameter of the push rod 86, facilitating the push rod 86 to pass through the heating element 82.

[0167] In some embodiments, as Figure 4 and Figure 10 shown, a second convex table surface 8531 is further provided on the inner wall where the first through hole 853 of the base 85 is located. The push rod 86 includes a first section and a second section. The outer diameters of the first section and the second section are different, and an inwardly concave first convex table surface 861 is formed at the connection between the first section and the second section. The second convex table surface 8531 of the push rod 86 abuts against the second convex table surface 8531 of the base 85.

[0168] In some embodiments, as Figure 8 shown, the heating portion 821 of the heating element 82 is provided as a heating disk with a mesh structure. The first conductive portion 8221 and the second conductive portion 8222 are respectively provided as rectangles, and the through hole 8212 is located at the center of the heating disk.

[0169] The heating plate is made of an alloy material with high resistivity. Suitable alloy materials include iron-chromium-aluminum materials, stainless steel materials, nickel-chromium alloy materials, pure nickel materials, or pure titanium materials. By providing a mesh structure on the heating plate, the heating part 821 has a suitable resistance, and at the same time, this mesh structure is also conducive to the aerosol generated by atomization on the heating part 821 passing through.

[0170] The conductive part is made of a metal material with excellent electrical conductivity. Suitable conductive metal materials include copper. The resistivity of the material used for the conductive part is significantly lower than the resistivity of the material used for the heating part 821. Therefore, during the process of the heating part 821 generating high-temperature heat, the heat generated by the conductive part is less. Thus, the conductive part can be clamped between the support part of the sealing seat 83 and the support member 84, while a part of the heating part 821 is placed on the support member 84, but the heating part 821 does not contact the sealing seat 83. It can be understood that during the energization process of the heating part 821, high-temperature heat can be generated. If the heating part 821 is in direct contact with the sealing seat 83, and the sealing seat 83 is made of a silicone material, when the high-temperature heat generated by the heating part 821 exceeds 400 °C, it will cause the sealing seat 83 to carbonize, thereby affecting the sealing performance of the sealing seat 83.

[0171] In some embodiments, as Figure 9 shown, four boss parts 842 are provided on the base part 841 of the support member 84, namely the opposite first boss part 8421 and second boss part 8422, and the opposite third boss part 8423 and fourth boss part 8424. The first boss part 8421 and the second boss part 8422 are respectively used to support the left and right sides of the heating part 821, and the third boss part 8423 and the fourth boss part 8424 are respectively used to support the front and rear ends of the heating part 821, so that the heating part 821 can be stably placed and fixed on the support member 84. It can be understood that in other alternative examples, a plurality of boss parts 842 can be provided on the base part 841 of the support member 84, and the number of the boss parts 842 is adaptively adjusted according to the shape and size of the heating part 821.

[0172] In some embodiments, the support member 84 is made of a dense ceramic material. The ceramic material can withstand high temperatures, and the boss part 842 of the support member 84 is arranged between the heating part 821 and the main body part 831 of the sealing seat 83, so as to be able to isolate the high-temperature heat generated by the heating part 821 from being transmitted to the main body part 831 of the sealing seat 83, thereby causing the sealing seat 83 to soften and affecting the sealing performance of the sealing seat 83.

[0173] It should be noted that dense ceramics are relative to porous ceramics. Dense ceramics do not have a porous structure, so it is difficult to store the atomized liquid in dense ceramics. Dense ceramics are only used to support the heating element 82.

[0174] In some embodiments, as Figures 2 to 4 shown, the atomization electrode 862 includes two conductive columns, namely the first conductive column 8621 and the second conductive column 8622. The first conductive column 8621 is electrically connected to the first conductive part 8221, and the second conductive column 8622 is electrically connected to the second conductive part 8222. The first conductive column 8621 penetrates through the base 85 and the main body 831 of the sealing seat 83 and extends into the first positioning hole 8331 to be electrically connected to the first conductive part 8221. The second conductive column 8622 penetrates through the base 85 and the main body 831 of the sealing seat 83 and extends into the second positioning hole 8332 to be electrically connected to the second conductive part 8222. In a specific implementation, as Figure 10 shown, two second conductive column holes 854 are provided on the base 85. As Figure 6 shown, two first conductive column holes 836 are provided on the main body 831 of the sealing seat 83. One of the second conductive column holes 854 and one of the first conductive column holes 836 are longitudinally connected along the mounting shell 81 and communicate with the first positioning hole 8331. The first conductive column 8621 sequentially passes through one of the second conductive column holes 854 and one of the first conductive column holes 836 and enters the first positioning hole 8331 to be electrically connected to the first conductive part 8221. The other second conductive column hole 854 and the other first conductive column hole 836 are longitudinally connected along the mounting shell 81 and communicate with the second positioning hole 8332. The second conductive column 8622 sequentially passes through one of the second conductive column holes 854 and one of the first conductive column holes 836 and enters the second positioning hole 8332 to be electrically connected to the second conductive part 8222.

[0175] Correspondingly, as Figure 9 shown, two avoidance holes 844 are further provided on the base part 841 of the support member 84. The two avoidance holes 844 are respectively located on both sides of the base part 841. One of the avoidance holes 844 is for the first conductive column 8621 to pass through, and the other avoidance hole 844 is for the second conductive column 8622 to pass through. In a specific implementation, the base part 841 of the support member 84 is arranged in a disc shape corresponding to the heating plate. Two extension platforms 843 are respectively provided at the left end and the right end of the base part 841. The two extension platforms 843 can be respectively received into the first positioning hole 8331 and the second positioning hole 8332. A part of the first convex part 8421 is located on one of the extension platforms 843, and another part of the first convex part 8421 is located on the base part 841. A part of the second convex part 8422 is located on the other extension platform 843, and another part of the second convex part 8422 is located on the base part 841. The two avoidance holes 844 are respectively arranged on the two extension platforms 843.

[0176] In some embodiments, asFigure 3 , Figure 7 and Figure 10 As shown, the atomizer assembly 100 is also provided with an air inlet hole 881, which is configured to be composed of a first air vent 855 located on the base 85 and a second air vent 835 located on the sealing seat 83, wherein the first air vent 855 is connected to the second air vent 835 along the longitudinal direction of the mounting shell 81, and the second air vent 835 is located on one side of the first clamping arm 8324 or the second clamping arm 8325.

[0177] The air inlet hole 881 formed by the combination of the first air hole 855 and the second air hole 835 is located on one side of the first clamping arm 8324 or the second clamping arm 8325, that is, the air inlet hole 881 is located on one side of the heating part 821, and the interval space between the heating part 821 and the base part 841 of the support member 84 is set as the atomization channel 883, that is, the air inlet hole 881 is located on one side of the atomization channel 883, and the air inlet hole 881 and the atomization channel 883 are staggered to prevent condensation from entering the air inlet hole 881.

[0178] like Figure 11 As shown, the mounting shell 81 has a first side wall 2411a and a second side wall 2411b opposite to each other, and the first clamping arm 8324 and the second clamping arm 8325 both extend between the first side wall 2411a and the second side wall 2411b, and one end of the first clamping arm 8324 abuts against the first side wall 2411a, and the other end is spaced apart from the second side wall 2411b, at which time the first clamping arm 8324 and the second side wall 2411b are spaced apart to form a first guide port 246. One end of the second clamping arm 8325 abuts against the second side wall 2411b, and the other end is spaced apart from the first side wall 2411a, at which time the second clamping arm 8325 and the first side wall 2411a are spaced apart to form a second guide port 247.

[0179] like Figure 11 As shown, the air inlet 881 is located on the side of the second clamping arm 8325 away from the first clamping arm 8324 , and the side of the first clamping arm 8324 away from the second clamping arm 8325 is provided with a space for communicating with the air flow channel 30 in the atomizer bomb 300 .

[0180] like Figure 11As shown, when the user inhales, the air flow flows from the air inlet hole 881 to the upper part of the sealing seat 83, then flows along the second clamping arm 8325 towards the first side wall 2411a and reaches the second diversion port 247. After the air flow flows into the second diversion port 247, it flows between the first clamping arm 8324 and the second clamping arm 8325 towards the second side wall 2411b, so as to carry the aerosol generated by atomization towards the first diversion port 246. After the air flow reaches the first diversion port 246, it flows out of the first diversion port 246 in a direction away from the second clamping arm 8325, and then continues to flow along the first clamping arm 8324 towards the first side wall 2411a, so as to flow into the air flow channel 30 in the atomization cartridge 300 (which can be understood in combination with Figure 28 and Figure 29 ).

[0181] That is to say, in this embodiment, when the user inhales the aerosol generating device 500, the flow path of the air flow is S-shaped, and the air flow passes through the position where the heating element 82 is located during the flowing process, so that the air can better mix with the aerosol and then flow into the user's mouth together, avoiding the situation that some aerosol does not flow out to the user's mouth together with the air, thereby affecting the taste.

[0182] Please refer to Figure 13 , the battery assembly 200 includes a mounting bracket 71 and a battery body 72.

[0183] Among them, as Figure 15 shown, the mounting bracket 71 is made of a rigid plastic material. The mounting bracket 71 includes opposite top covers 7131 and bottom covers 7132 and side walls 7133 connected between the top cover 7131 and the bottom cover 7132. The top cover 7131, the bottom cover 7132 and the side walls 7133 enclose to form a battery cavity 711. An opening 714 is also provided on the mounting bracket 71. The battery body 72 can be inserted into the battery cavity 711 through the opening 714, and the battery body 72 can be removed from the battery cavity 711 through the opening 714.

[0184] Since the battery body 72 is removably received in the battery cavity 711, it is beneficial for the battery body 72 to be recycled, meeting the European environmental protection requirements.

[0185] Please combine Figure 13 and Figure 14 , when a part of the battery assembly 200 is received in the second cavity 812, the opening 714 is blocked by the atomizer 810, thereby preventing the battery body 72 from being exposed through the opening 714, which is not conducive to the safe use of the battery body 72.

[0186] When the user needs to replace or recycle the battery body 72, the battery assembly 200 is removed out of the second cavity 812, and the opening 714 is exposed. The user can move the battery body 72 out of the battery cavity 711 through the opening 714. When the user needs to install the battery body 72, the battery body 72 is received into the battery cavity 711 through the opening 714, and the operation is simple and fast.

[0187] It should be understood that the opening 714 is blocked by the atomizer 810. When the opening 714 is on one side of the mounting frame 71, the opening 714 is blocked by the mounting shell 81. When the opening 714 is on the top cover of the mounting frame 71, the opening 714 is blocked by the atomizer 810.

[0188] In some embodiments, referring to Figure 15 and Figure 16 , only a part of the bottom cover 7132 of the mounting frame 71 is received in the second cavity 812, and the other part of the bottom cover 7132 of the mounting frame 71 is exposed outside the mounting shell 81. An operation part 712 is arranged on the bottom cover 7132 of the mounting frame 71, and the operation part 712 is arranged on the part of the bottom cover 7132 located outside the mounting shell 81. The battery assembly 200 is configured to drive the battery assembly 200 to be removed out of the second cavity 812 by applying an external force to the operation part 712, or the battery assembly 200 is configured to drive the battery assembly 200 to be received into the second cavity 812 by applying an external force to the operation part 712, so that the separation operation or the installation operation of the battery assembly 200 and the atomizer 810 is simple and fast, improving the user experience.

[0189] In one example, the operation part 712 is arranged as a groove, and the groove provides a handle position, so as to facilitate applying an external force to the battery assembly 200.

[0190] In some embodiments, referring to Figure 14 and Figure 16 , the battery assembly 200 is configured to be removed out of the second cavity 812 or received into the second cavity 812 along the longitudinal direction of the mounting shell 81. The longitudinal direction of the mounting shell 81 is the Y direction as shown in Figure 4 . Correspondingly, the battery assembly 200 is arranged to be inserted into or removed out of the second cavity 812 through the bottom open end of the mounting shell 81, so that the mounting shell 81 can block the mounting frame 71 of the battery assembly 200 and the battery body 72 as much as possible, maintaining the integrity of the overall structure of the aerosol generating device 500.

[0191] In some embodiments, referring to Figures 15 to 18, the battery assembly 200 further includes two power supply electrodes 63. Both of the two power supply electrodes 63 are conductive elastic sheet structures. The two power supply electrodes 63 are respectively arranged to be electrically connected to the two atomizing electrodes 862 of the atomizer 810. A first assembly groove 7151 and a second assembly groove 7152 are provided on the top cover 7131 of the mounting bracket 71. The first power supply electrode 631 is fixed in the first assembly groove 7151, and the second power supply electrode 632 is fixed in the second assembly groove 7152.

[0192] Since the conductive elastic sheet has elasticity, after the battery assembly 200 is inserted into the second cavity 812, the power supply electrode 63 can stably abut against the atomizing electrode 862 of the atomizer 810, so that the battery assembly 200 and the atomizer 810 maintain a stable electrical connection. It can be understood that if the power supply electrode 63 is replaced with an electrode post in the related art, the contact area at the top end of the electrode post is limited, so that a stable electrical connection between the atomizing assembly and the power supply assembly cannot be ensured.

[0193] In some embodiments, referring to Figures 15 to 18 , both of the two power supply electrodes 63 are arranged to be bent structures. The two power supply electrodes 63 include a first power supply electrode 631 and a second power supply electrode 632. As Figure 18 shown, the first power supply electrode 631 includes a first bent section 6311, a second bent section 6312, and a third bent section 6313 that are connected in sequence. The first bent section 6311 and the second bent section 6312 are received in the first assembly groove 7151, and the third bent section 6313 is located on the top end surface of the mounting bracket 71 and abuts against one of the atomizing electrodes 862 of the atomizer 810. In an example, the third bent section 6313 is arranged to be an arch structure, and the top end surface of the third bent section 6313 is arranged to be a plane, so as to increase the elasticity of the third bent section 6313 and form a stable electrical connection surface between the third bent section 6313 and the atomizing electrode 862.

[0194] In a specific implementation, the second power supply electrode 632 includes four bending segments, namely a fourth bending segment 6321, a fifth bending segment 6322, a sixth bending segment 6323, and a seventh bending segment 6324. The fourth bending segment 6321 and the fifth bending segment 6322 are received in the second assembly groove 7152. The sixth bending segment 6323 is located on the top surface of the mounting bracket 71 and abuts against another atomizing electrode 862 of the atomizer 810. The seventh bending segment 6324 extends into the battery cavity 711 and abuts against the top of the battery body 72. In an example, the sixth bending segment 6323 is arranged as an arch structure, and the top surface of the sixth bending segment 6323 is arranged as a flat surface, so as to increase the elasticity of the sixth bending segment 6323 and form a stable electrical connection surface between the sixth bending segment 6323 and the atomizing electrode 862. The seventh bending segment 6324 is inclined, so that the second power supply electrode 632 has sufficient elasticity to facilitate abutment with the battery body 72.

[0195] In some embodiments, referring to Figure 13 and Figure 19 , the battery assembly 200 further includes a frame seal 73, a control board 74, and an airflow induction switch 75.

[0196] The frame seal 73 is arranged inside the mounting bracket 71. Multiple sealing ribs are arranged on the outer surface of the frame seal 73, so as to form a sealed connection between the frame seal 73 and the mounting bracket 71. As Figure 20 shown, the frame seal 73 is provided with a receiving cavity 731, and the receiving cavity 731 is used to receive the airflow induction switch 75.

[0197] As Figure 13 or Figure 19 shown, the control board 74 is arranged between the frame seal 73 and the battery body 72. The control board 74 is connected to the bottom end of the battery body 72 and the airflow induction switch 75. The control board 74 is arranged to be electrically connected to the heating element 82 of the atomizer 810, so as to control whether the heating element 82 is turned on for heating.

[0198] The airflow induction switch 75 includes an opposite first side 751 and a second side 752. The first side 751 is arranged as a sensing end, and the second side 752 is arranged as an atmospheric pressure end. The first side 751 is connected to the airflow channel inside the aerosol generating device 500, and the second side 752 is connected to the external air pressure. When the user sucks, a negative pressure is generated in the airflow channel inside the aerosol generating device 500. When the negative pressure sensed by the first side 751 reaches the threshold of the airflow induction switch 75, the airflow induction switch 75 converts the pressure difference signal into an electrical signal and transmits it to the control board 74, and the control board 74 further drives the battery body 72 to provide power for the heating element 82 of the atomizer 810.

[0199] In some implementations, such asFigure 13 and Figure 19 As shown in Figure 19 , the battery assembly 200 is provided with an air intake structure. The air intake structure includes an air intake port 716 provided on the bottom cover 7132 of the mounting bracket 71 and an air intake passage 62 provided between the side wall 7133 of the mounting bracket 71 and the mounting shell 81. Among them, the opening 714 on the mounting bracket 71 is provided on the side wall 7133 of the mounting bracket 71. Therefore, a sufficient gap is formed between the side wall where the opening 714 of the mounting bracket 71 is located and the mounting shell 81. This gap is set as the air intake passage 62, and the air intake port 716 is communicated with the air intake passage 62.

[0200] In some embodiments, with continued reference to Figure 13 、 Figure 16 and Figure 19 Figure 19 , the air intake structure includes a first ventilation hole 732 located on the frame seal 73 and a second ventilation hole 741 located on the control board 74. The first ventilation hole 732 and the second ventilation hole 741 are communicated longitudinally along the mounting bracket 71. Among them, the longitudinal direction of the mounting bracket 71 is the same as the Y direction of Figure 4 Figure 4 . The first ventilation hole 732 and the second ventilation hole 741 are used to communicate the air intake port 716 and the air intake passage 62. External air enters the first ventilation hole 732 and the second ventilation hole 741 through the air intake port 716 and then enters the air intake passage 62. Among them, the air intake passage 62 is staggered from the second ventilation hole 741 and the first ventilation hole 732, so as to prevent the condensate entering the air intake passage 62 from leaking to the outside through the second ventilation hole 741 and the first ventilation hole 732.

[0201] In some embodiments, as shown in Figure 16 Figure 16 , the battery assembly 200 is further provided with an induction air passage structure of the air flow induction switch 75. The induction air passage structure includes a third ventilation hole 733 located on the frame seal 73. One end of the third ventilation hole 733 is communicated with the air intake port 716, and the other end of the third ventilation hole 733 is communicated with the second side 752 of the air flow induction switch 75. The induction air passage structure further includes a fourth ventilation hole 742 located on the frame seal 73. One end of the fourth ventilation hole 742 is communicated with the air intake passage 62, and the other end of the fourth ventilation hole 742 is communicated with the first side 751 of the air flow induction switch 75.

[0202] In some implementations, as shown in Figure 16As shown, the battery assembly 200 further includes a button 61, which is mounted on the mounting bracket 71. The button 61 can be disposed on the bottom surface of the mounting bracket 71 or on the side wall of the mounting bracket 71. The button 61 is electrically connected to the control board 74. By operating the button 61, the heating element 82 of the atomizer 810 can be driven to dry burn, thereby removing the carbon deposits on the heating element 82. It can be understood that the heating element 82 generates high temperature through dry burning, so that the carbon deposits on the heating element 82 are vaporized at high temperature, thus preventing the heating element 82 from accumulating too much carbon deposits after long-term high-temperature heating, which affects the taste of the aerosol generated by its atomization.

[0203] As Figure 2 , Figure 13 or Figure 28 shown, according to a second aspect of the present application, an aerosol generating device 500 is provided. The aerosol generating device 500 includes an atomizer cartridge 300 and the atomization main unit 400 in any one of the above embodiments. The atomizer cartridge 300 is used to store the atomization liquid, and the atomizer cartridge 300 is mounted on the atomization assembly 100, and the atomizer cartridge 300 is used to provide the atomization liquid to the atomizer 810.

[0204] Specifically, reference can be made to Figure 2 , the atomizer cartridge 300 is provided with a liquid storage chamber 251 and a liquid outlet passage 912 communicating with the liquid storage chamber 251. The liquid storage chamber 251 stores the atomization liquid. The atomization liquid can flow out of the liquid storage chamber 251 through the liquid outlet passage 912. A liquid absorbing member 28 (such as absorbent cotton, absorbent ceramic, etc.) can be disposed at the liquid outlet of the liquid outlet passage 912. The liquid absorbing member 28 adsorbs the atomization liquid from the liquid outlet passage 912, and the liquid absorbing member 28 abuts against the heating element 82 of the atomizer 810. Furthermore, the heating element 82 can heat and atomize the atomization liquid in the liquid absorbing member 28.

[0205] It can be understood that since the aerosol generating device 500 includes the atomization main unit 400 of any one of the above embodiments, the aerosol generating device 500 has all the beneficial effects of the above atomization main unit 400, and the present disclosure will not elaborate herein.

[0206] It should be noted here that the atomizer cartridge 300 can be installed on the atomization assembly 100 in a non-detachable manner or in a detachable manner. For example, optionally, in one embodiment, as Figure 10As shown, the atomizing cartridge 300 includes a housing 10 and a liquid cup 20. The liquid cup 20 is installed inside the housing 10 and is used to store the atomizing liquid and supply the atomizing liquid to the atomizer 810. The housing 10 is detachably connected to the mounting shell 81. That is to say, the atomizing cartridge 300 and the atomizing assembly 100 are also detachably connected. In this way, when the atomizing liquid in the atomizing cartridge 300 is consumed, the atomizing cartridge 300 can be detached separately and a new atomizing cartridge 300 can be replaced, without the need to replace the atomizing assembly 100 together, so that the atomizing assembly 100 can be used until it is scrapped, avoiding waste and reducing the use cost.

[0207] It should be noted that the housing 10 of the atomizing cartridge 300 and the mounting shell 81 of the atomizing assembly 100 can be detachably connected by means of threaded connection, screw connection, snap connection, magnetic attraction connection, etc. The specific connection method can be flexibly selected according to needs.

[0208] For example, optionally, one of the housing 10 and the mounting shell 81 is press-fitted into the other. Specifically, in one embodiment, please refer to Figure 2 and Figure 4 , the mounting shell 81 forms a first cavity 811 on the upper side of the atomizer 810. The first cavity 811 has a first opening 512 opposite to the atomizer 810, and the housing 10 of the atomizing cartridge 300 is press-fitted into the first cavity 811. In this way, during assembly, as long as the atomizing cartridge 300 is inserted into the mounting shell 81 with force, and during disassembly, as long as the atomizing cartridge 300 is pulled out of the first cavity 811 with force, the assembly and disassembly are very convenient.

[0209] Of course, in another embodiment, it is also possible that the housing 10 of the atomizing cartridge 300 is provided with a cavity for the installation to be inserted, and the mounting shell 81 is press-fitted into the housing 10 after being inserted, which is also convenient for the assembly and disassembly of the atomizing cartridge 300 and the atomizing assembly 100.

[0210] Optionally, in one embodiment, reference can be made to Figure 23 and Figure 24 , Figure 23 is a schematic structural diagram of the housing 10, Figure 24 is Figure 23 a structural sectional view of the housing 10 in Figure 23 The housing 10 is provided with an assembly cavity 11, an assembly opening and an air outlet 13. The assembly opening and the air outlet 13 are respectively located at both ends of the assembly cavity 11 and are respectively communicated with the assembly cavity 11. Specifically, the overall outer habit of the housing 10 is approximately rectangular parallelepiped-shaped. Therefore, reference can be made to Figure 24As shown, the interior of the outer shell 10 is hollow to form an assembly cavity 11. At both ends of the outer shell 10 in the height direction, an assembly opening and an air outlet hole 13 are respectively provided. The assembly opening is located at the lower end of the outer shell 10 and is communicated with the assembly cavity 11 for installing the liquid cup 20 into the assembly cavity 11. The air outlet hole 13 is located at the upper end of the outer shell 10, and the air outlet hole 13 communicates the assembly cavity 11 with the outside of the outer shell 10. When the user sucks, the air flow flows from the assembly cavity 11 into the air outlet hole 13 and then from the air outlet hole 13 into the user's mouth.

[0211] As Figure 21 or Figure 22 shown, the liquid cup 20 is used to store the atomizing liquid, and the liquid cup 20 is installed in the assembly 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 assembly cavity 11. One end of the air flow channel 30 is communicated with the assembly opening, and the other end is communicated with the air outlet hole 13.

[0212] Specifically, in this embodiment, reference can be made to Figure 25 , 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 opening 252 communicated 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 opening 252, and a sealing member 27 is further 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. The cover body 26 is also penetrated with a liquid outlet channel, and a liquid absorbing member 28 is provided at the liquid outlet of the liquid outlet channel close to the assembly opening. The atomizing liquid flows from the liquid storage cavity 251 into the liquid outlet channel and then from the liquid outlet channel to the liquid absorbing member 28. Reference can be made to Figure 29 , the liquid absorbing member 28 is used to abut against the heating element 82 on the atomizing assembly 100, so that the heating element 82 can heat and atomize the atomizing liquid on the liquid absorbing member 28.

[0213] 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 21 shown, after the liquid cup 20 is installed in the assembly cavity 11 of the outer shell 10, 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 assembly cavity 11. One end of the air flow channel 30 is communicated with the assembly opening, and the other end is communicated with the air outlet hole 13. After the atomizing cartridge 300 is assembled to the atomizing assembly 100, the assembly opening can be communicated with the atomizing channel 883 on the atomizing assembly 100, so that the air flow channel 30 can be communicated with the atomizing channel 883 through the assembly opening. 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.

[0214] It should be noted that, in order to form an air flow channel 30 at intervals between the outer wall of the liquid cup 20 and the inner wall of the assembly cavity 11, the volume of the liquid cup 20 can be made smaller than the volume of the assembly cavity 11. When the liquid cup 20 is installed in the assembly cavity 11, the liquid cup 20 cannot fill the assembly cavity 11 completely, but only fills a part of the assembly 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 be communicated with the assembly 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 from the air outlet hole 13.

[0215] Alternatively, the overall volume of the liquid cup 20 is basically adapted to the volume of the assembly cavity 11. An air guiding groove is recessed on the outer wall of the liquid cup 20 or the inner wall of the assembly cavity 11. The air guiding groove extends from the assembly opening 12 to the air outlet hole 13, thereby forming the air flow channel 30. The air guiding 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 assembly cavity 11, as long as it can communicate the assembly opening 12 and the air outlet hole 13.

[0216] In summary, it can be understood that the air flow channel 30 in the atomizing cartridge 300 of the present application is formed at intervals 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, making the forming method of the air flow channel 30 very simple and convenient, simplifying the production process of the atomizing cartridge 300, and effectively solving the technical problem that the forming process of the air flow channel 30 in the existing atomizing cartridge 300 is relatively complex.

[0217] Optionally, in an embodiment, as Figure 21 or Figure 22 shown, the assembly opening and the air outlet hole 13 are respectively located at both ends in the height direction of the housing 10, and 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 at intervals between the outer wall of the liquid cup 20 and the inner wall of the assembly cavity 11, and this gap extends along the height direction of the housing 10 to form the first air duct 31. It can be understood that since the assembly opening 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, so that the air flow can flow from the assembly opening 12 to the air outlet hole 13 faster.

[0218] It should be noted that the first air duct 31 can be provided with one or multiple. For example, optionally, in an embodiment, as Figure 26As shown, the outer wall of the liquid cup 20 includes a first outer wall 21 and a plurality of second outer walls 22. The first outer wall 21 and the plurality of second outer walls 22 form the outer peripheral wall of the liquid cup. The outer peripheral wall of the liquid cup and the top wall 23 of the cup body form 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 top wall 23 of the cup body. As Figure 24 shown, the inner wall of the assembly cavity 11 includes a first inner wall 111 and a plurality of second inner walls 112. The first inner wall 111 and the plurality of second inner walls 112 form the inner peripheral wall of the assembly cavity 11. The inner peripheral wall of the assembly cavity 11 and the top wall 113 of the cavity form the inner wall of the assembly cavity 11. Specifically, in this embodiment, the inner wall of the assembly cavity includes one first inner wall 111, three second inner walls 112, and one top wall 113 of the cavity.

[0219] Among them, please refer to Figure 21 , Figure 24 , Figure 25 and Figure 26 . 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. The plurality of second outer walls 22 and the plurality of second inner walls 112 are in one-to-one correspondence and are closely attached to each other. That is, in this embodiment, only one first air passage 31 is formed between the liquid cup 20 and the outer shell 10. This can achieve the concentrated flow of air, which is convenient for controlling the flow direction of air and can avoid the situation that the air flow is dispersed and affects the taste.

[0220] It should be noted here that in order to make the plurality of second outer walls 22 and the plurality of second inner walls 112 in one-to-one correspondence and closely attached, the liquid cup 20 can be press-fitted into the assembly cavity 11. When assembling, the liquid cup 20 is inserted into the assembly cavity 11 with force. Except for the first outer wall 21 and the first inner wall 111 being spaced apart, the plurality of second outer walls 22 and the plurality of second inner walls 112 are closely attached to each other. Alternatively, an adhesive can be provided between the plurality of second outer walls 22 and the plurality of second inner walls 112 so that the plurality of second outer walls 22 and the plurality of second inner walls 112 are bonded together.

[0221] Optionally, in one embodiment, as Figure 23 , Figure 24 and Figure 26As 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 side wall 21 extends along the height direction of the liquid cup 20 and is located on one side in the length direction of the liquid cup 20. The first inner side wall 111 extends along the height direction of the outer shell 10 and is located on one side in the length direction of the outer shell 10. Since the first air passage 31 is formed by the spacing between the first outer side wall 21 and the first inner side wall 111, the first air passage 31 is located on one side in 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 atomizing cartridge 300 (such as the flat design of the mouthpiece 15), making it convenient for the user to put it in the mouth for inhalation.

[0222] Optionally, in one embodiment, as Figure 24 shown, the inner wall of the assembly cavity 11 further includes a cavity top wall 113 opposite to the assembly opening 12. The air outlet hole 13 penetrates the cavity top wall 113, and the air outlet hole 13 is centrally arranged in the length direction of the outer shell 10. This can enable the air flow (i.e., the aerosol mixed gas) to flow into the oral cavity from the middle position in 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.

[0223] As Figure 21 shown, the outer wall of the liquid cup 20 further includes a cup body top wall 23 spaced opposite to the cavity top wall 113. The cup body top wall 23 and the cavity top wall 113 are spaced to form a second air passage 32. The second air passage 32 extends along the length direction of the outer shell 10, and one end of the second air passage 32 is communicated with the first air passage 31, and the other end is communicated with the air outlet hole 13. The first air passage 31 and the second air passage 32 together constitute the air flow channel 30.

[0224] It can be understood that by making the cup body top wall 23 and the cavity top wall 113 spaced to form the second air passage 32, and the second air passage 32 connects the first air passage 31 and the air outlet hole 13, it can ensure that the air flow can flow from the middle position in the user's mouth to the oral cavity while the first air passage 31 is located on one side in the length direction of the outer shell 10, that is, it can not only achieve the flat design of the atomizing cartridge 300, but also ensure the inhalation taste.

[0225] Optionally, in one embodiment, as Figure 21 or Figure 25 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 body top wall 23, and the second diversion section 212 is inclined towards the side where the air outlet hole 13 is located relative to the first diversion section 211.

[0226] Specifically, in Figure 21 , the lower end of the first diversion section 211 is located at the assembly 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 top wall 23 of the cup body. 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, enabling the air flow to flow from the first air passage 31 to the second air passage 32 and the air outlet hole 13 faster and more smoothly.

[0227] Optionally, in an embodiment, as Figure 21 or Figure 25 shown, a first arc-shaped diversion section 24 is further connected between the second diversion section 212 and the top wall 23 of the cup body. 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 top wall 23 of the cup body, the turning of the air flow can be made smoother, improving the user experience.

[0228] Optionally, in an embodiment, as Figure 21 or Figure 24 shown, a second arc-shaped diversion section 114 is further connected between the first inner side wall 111 and the top wall 113 of the cavity. Similarly, when the air flow flows along the first inner side wall 111 to the top wall 113 of the cavity, the air flow needs to turn and flow to the air outlet hole 13. Therefore, by providing the second arc-shaped diversion section 114 between the first inner side wall 111 and the top wall 113 of the cavity, the turning of the air flow can be further made smoother, improving the user experience.

[0229] Optionally, in an embodiment, as Figure 24 shown, a positioning boss 14 protrudes from the top wall 113 of the cavity. The positioning boss 14 extends from the top wall 113 of the cavity towards the assembly opening 12, and as Figure 1 shown, the positioning boss 14 abuts against the top wall 23 of the cup body. In this way, the positioning of the liquid cup 20 can be achieved during the combined installation, avoiding the situation that the depth of the liquid cup 20 inserted into the assembly cavity 11 is too large or too small, which may lead to the second air passage 32 being too large or too small.

[0230] 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 achieve the positioning of the liquid cup 20 and does not affect the air flow towards the air outlet hole 13.

[0231] For example, optionally, in an embodiment, as Figure 21 or Figure 24As shown, the positioning boss 14 is located on the side of the air outlet 13 away from the first inner wall 111, so that before the air flow reaches the air outlet 13, the positioning boss 14 can be prevented from obstructing the air flow. And in this embodiment, the positioning boss 14 has a guiding side wall 141 facing the first inner wall 111, and the guiding side wall 141 is smoothly connected to the inner wall of the air outlet 13, so that 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.

[0232] Optionally, in one embodiment, as Figure 27 shown, the liquid cup 20 is press-fitted into the outer shell 10 in the width direction of the outer shell 10. Specifically, in the width direction of the outer shell 10, the width of the assembly cavity 11 is adapted to the width of the liquid cup 20. During assembly, the liquid cup 20 can be forced into the assembly cavity 11, so that both sides of the liquid cup 20 in the width direction are press-fitted into the assembly 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.

[0233] Optionally, in one embodiment, as Figure 24 shown, the air outlet 13 includes a diffusion section 131. Please also refer to Figure 2 , one end of the diffusion section 131 is connected to the air flow channel 30, and the other end is connected to the outside of the outer shell 10, and 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 connected to the air flow channel 30 is smaller, and the inner diameter of the end connected to 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.

[0234] 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.

[0235] Or, optionally, in one embodiment, as Figure 4 shown, the air outlet 13 further includes a connection section 132. Please also refer to Figure 22 , the diffusion section 131 is connected to the air flow channel 30 through the connection section 132, and the connection section 132 is cylindrical, that is, the inner diameter at each position in the connection section 132 is set to be the same, so as to prevent the aerosol from diffusing prematurely in the air outlet 13.

[0236] Optionally, in one embodiment, as Figure 30 shown, 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 arranged 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.

[0237] 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.

[0238] Specifically, in this embodiment, as Figures 30 to 32 shown, the liquid cup 20 includes a cup body 25 and a cup cover assembly 914. Among them, as Figure 12 shown, a liquid storage cavity 251 is arranged in the cup body 25, and an installation opening 252 communicating with the liquid storage cavity 251 is arranged 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 clamping 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 from the assembly gap between the cup body 25 and the cover body 26.

[0239] The cover body 26 is also provided with a liquid outlet channel 912 penetrating through it. As Figure 33 shown, Figure 33 is Figure 32 a partial structural schematic diagram of the liquid cup 20 in

[0240] Of course, in some other embodiments, the cup body 25 and the cover body 26 can be integrally formed. At this time, the openings for injecting the atomized liquid and installing the first seal 920 can be arranged at the upper end of the liquid cup 20 (the upper and lower are referenced by the orientation indication in Figure 10 ).

[0241] As Figure 30 or Figure 31As shown, the first seal 920 is disposed in the liquid storage chamber 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 a part of the sealing 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 sealing block 921 blocking the liquid outlet channel 912. Reference can be made to Figure 38 , 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.

[0242] Specifically, the outer shape of the sealing block 921 can be adapted to the liquid outlet channel 912. For example, in the Figure 34 shown structural solution, the liquid outlet channel 912 is a circular channel. Therefore, as Figure 35 shown, the overall outer shape of the sealing block 921 is also designed as a cylindrical shape, so as to 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 light weight, avoiding excessive weight of the liquid cup 20.

[0243] It should be noted that, in combination with Figure 30 and Figure 33 , it can be understood 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 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 blocks at the middle position of the liquid outlet channel 912), or 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).

[0244] As Figure 30 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 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.

[0245] In this embodiment, when the sealing block 921 blocks the liquid outlet channel 912, the elastic arms 922 are also in a deformed state and maintain a tendency to drive the sealing block 921 to block the liquid outlet channel 912. In this way, the sealing block 921 is not easily separated from the liquid outlet channel 912 to open the liquid outlet channel 912, achieving a good sealing effect.

[0246] 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 elastic sheet. One end of the metal elastic sheet 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.

[0247] For another example, the elastic arms 922 can be provided with two, three, four, five, etc. A plurality of elastic arms 922 can be arranged at intervals along the circumferential direction of the sealing block 921, and each elastic arm 922 is connected to the sealing block 921 at one end and connected to the cup body 25 or the cover body 26 at the other end. In this way, the acting force on the sealing block 921 can be increased, so that the sealing block 921 can block the liquid outlet channel 912 more tightly and improve 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.

[0248] Further, in this embodiment, the sealing block 921 is further configured to be pushed open and located outside the liquid outlet channel 912, thereby opening the liquid outlet channel 912. At this time, the elastic arms 922 are also in a deformed state and have a tendency to drive the sealing block 921 to block the liquid outlet channel 912.

[0249] Reference can be made to Figure 37 and Figure 38 , Figure 37 which is a structural cross-sectional view of an embodiment of the aerosol atomizing cartridge 300 of the present application, Figure 38 which is a partial structural cross-sectional view of the aerosol generating device 500 of the present application. A push rod 86 can be provided on the atomizing assembly 100. The push rod 86 extends along the axial direction of the liquid outlet channel 912. When the atomizing cartridge 300 with the liquid cup 20 is installed on the atomizing assembly 100, the push rod 86 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, and then the atomizing liquid in the liquid storage cavity 251 can flow out through the liquid outlet channel 912 and flow onto the atomizing assembly 100 to be atomized by the atomizing assembly 100.

[0250] Since the elastic arm 922 still has a tendency to drive the sealing block 921 to block the liquid outlet channel 912, when the atomizing cartridge 300 is removed from the atomizing assembly 100 and the sealing block 921 is no longer pressed by the push rod 86, 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 atomizing liquid in the liquid cup 20 from flowing out and leaking through the liquid outlet channel 912.

[0251] In summary, it can be understood that in the liquid cup 20 of the embodiment of the present application, by providing a first sealing member 920 in the liquid storage cavity 251 of the liquid cup 20, the first sealing member 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 has 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 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 preventing the atomizing liquid from flowing out and leaking through the liquid outlet channel 912.

[0252] When in use, the atomizing cartridge 300 can be installed on the atomizing assembly 100. The sealing block 921 can be pushed open by the push rod 86 extending into the liquid outlet channel 912 to open the liquid outlet channel 912, so that the atomizing liquid in the liquid cup 20 can flow out through the liquid outlet channel 912 and be atomized by the atomizing assembly 100.

[0253] Since the elastic arm 922 still has 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 atomizing cartridge 300 is removed from the atomizing assembly 100 and the sealing block 921 is no longer pressed by the push rod 86, 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 atomizing liquid in the liquid cup 20 from flowing out and leaking through the liquid outlet channel 912.

[0254] 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, Figure 35 in, 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 arms 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.

[0255] 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 30 and Figure 31 shown, the first seal 920 further includes a fixing ring 923. One end of the elastic arm 922 is connected to the seal block 921, and the other end is connected to the fixing ring 923. The fixing ring 923 is fixedly connected to the liquid cup 20.

[0256] Specifically, in this embodiment, the seal block 921, the multiple elastic arms 922 and the fixing ring 923 are integrally formed. The fixing ring 923 surrounds the seal block 921, and the elastic arms 922 are connected between the seal 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.

[0257] It can be understood that by providing the fixing ring 923, the multiple 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 multiple elastic arms 922 to the liquid cup 20 one by one, which simplifies the assembly process, thereby improving the assembly efficiency and reducing the production cost.

[0258] 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 32 shown, a first engaging structure 9131 is provided on the inner wall of the liquid storage cavity 251. As Figure 35 shown, a second engaging structure 231 is provided on the fixing ring 923. Please refer to Figure 30 , 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.

[0259] 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 33 shown, the first engaging structure 9131 includes an adjacent first annular convex 1311 and a first annular slot 1312. As Figure 35 shown, the second engaging structure 231 includes an adjacent second annular convex 2311 and a second annular slot 2312; Please refer to Figure 30The first annular clamping protrusion 1311 is inserted into the second annular clamping groove 2312 , and the second annular clamping protrusion 2311 is inserted into the first annular clamping groove 1312 .

[0260] That is, the first engaging structure 9131 and the second engaging structure 231 are engaged with each other by plugging into each other. 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, avoid the situation where the elastic arm 922 is driven to separate the fixing ring 923 from the liquid cup 20 when the force is applied, and ensure the stable installation of the first seal 920.

[0261] In addition, it can be understood that if the length of the first annular protrusion 1311 inserted into the second annular groove 2312 is too small, or the length of the second annular protrusion 2311 inserted into the first annular groove 1312 is too small, the fixing ring 923 will be more easily pulled out of the liquid cup 20 by the elastic arm 922. Because, in order to avoid the above problems, optionally, the length of the first annular protrusion 1311 extending into the second annular groove 2312 and the length of the second annular protrusion 2311 extending into the first annular groove 1312 are both greater than or equal to 1.5 mm. This can avoid the situation where the fixing ring 923 is pulled out of the liquid cup 20 due to the small insertion depth.

[0262] Optionally, in one embodiment, if Figure 35 or Figure 36 As 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. The first ring body 233 and the second ring body 234 are spaced apart to form a second annular groove 2312. The second ring body 234 constitutes a second annular protrusion 2311. One end of the elastic arm 922 is connected to the first ring body 233.

[0263] Please combine Figure 30 , Figure 33 and Figure 36It can be understood that 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 convex 2311) and the first annular convex 1311, thereby preventing the fixing ring 923 from coming loose 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, better overcome the pulling force of the elastic arm 922, and enable the fixing ring 923 to be more stably fixed on the liquid cup 20.

[0264] Optionally, in one embodiment, as Figure 32 shown, the liquid cup 20 includes a cup body 25 and a cup cover assembly 914. The cup body 25 has a liquid storage cavity 251 and an installation port 252 communicating with the liquid storage cavity 251. The cup cover assembly 914 is covered at the installation port 252, and a liquid outlet channel 912 penetrates through the cup cover assembly 914; wherein, the sealing block 921 abuts against the cup cover assembly 914 and blocks the liquid outlet channel 912. Please also combine Figure 30 and Figure 36 , the cup cover assembly 914 also abuts against the side of the base ring body 232 away from the first annular slot 1312 to limit the second ring body 234 from disengaging from the first annular slot 1312.

[0265] Specifically, in this embodiment, please combine Figure 30 , Figure 33 and Figure 36 to understand that 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 first move downward and disengage from the first annular 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 engagement with the cup body 25 can be restricted. Therefore, in this embodiment, by making the cup cover assembly 914 also abut against the side of the base ring body 232 away from the first annular slot 1312, that is, the cup cover 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 slot 1312, and further the fixing ring 923 is stably engaged with the cup body 25.

[0266] Among them, it should be noted that the cup cover assembly 914 may only include a cover body 26, or may include a cover body 26 and other components. For example, optionally, in one embodiment, as Figure 32 orFigure 33 As shown, the cup lid assembly 914 includes a lid body 26 and a second seal 27. The lid body 26 is snap-fitted onto the locking hole 133 of the cup body 25 through a snap 1411, and a liquid outlet channel 912 penetrates through the lid body 26. The second seal 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. Additionally, in this embodiment, reference can be made to Figure 10 , the second seal 27 also abuts against the base ring body 232. In this way, there is also a certain sealing effect between the fixing ring 923 and the second seal 27, further improving the sealing performance of the entire liquid cup 20.

[0267] In addition, 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 Figure 33 and Figure 34 shown, an air pressure balance channel 1412 is further provided on the lid body 26. One end of the air pressure balance channel 1412 is located at the top of the lid body 26 and communicates with the liquid storage cavity 251, and the other end is located at the bottom of the lid 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 the end of the air pressure balance channel that communicates with the liquid storage cavity 251. In this way, the air pressure balance channel 1412 can be sealed when the air pressures inside and outside the liquid cup 20 are balanced, preventing the atomized liquid from flowing out through the air pressure balance channel 1412.

[0268] 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 the end of the air pressure balance channel 1412 that communicates with the liquid storage cavity 251 under the action of the internal and external pressure difference. In this way, 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 further ensuring that the atomized liquid can continuously flow out from the liquid outlet channel 912.

[0269] Optionally, in one embodiment, as Figure 36 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, to avoid breakage between the first ring body 233 and the base ring body 232, which may cause the elastic arm 922 to be disconnected from the fixing 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. In this way, the connection stability between the elastic arm 922 and the fixing ring 923 can be improved, avoiding disconnection between the elastic arm 922 and the fixing ring 923.

[0270] Optionally, in one embodiment, as Figure 35 shown, the fixing ring 923 has opposite length and width directions; on the length direction of the fixing ring 923, elastic arms 922 are respectively connected to both sides of the sealing block 921, and / or, on the width direction of the fixing ring 923, elastic arms 922 are respectively connected to both sides of the sealing block 921.

[0271] Specifically, in this embodiment, the overall shape of the fixing ring 923 is approximately rectangular ring-shaped, so the fixing ring 923 has opposite length and width directions, and the dimension of the fixing ring 923 in its length direction is greater than its dimension 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.

[0272] For 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 fixing ring 923, so that the length of the elastic arms 922 can be relatively long, to reduce the thrust required to push open the sealing block 921, making it easier and more convenient to install the atomizing cartridge 300 on the atomizing assembly 100.

[0273] Or, the two elastic arms 922 can also be located on opposite sides of the sealing block 921 along the width direction of the fixing ring 923, so that 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 atomizing liquid.

[0274] Optionally, in one embodiment, as Figure 36 shown, the sealing block 921 has a sealing end 9211 at one end in its axial direction, as Figure 33 shown, the liquid outlet channel 912 has an inner liquid outlet 121 communicating with the liquid storage cavity 251, and 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 30 shown, the sealing end 9211 abuts against the inclined sealing surface 1211.

[0275] 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 atomizing liquid due to the existence of gaps.

[0276] Optionally, in one embodiment, as Figure 36 shown, the sealed 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 rounding the periphery of the sealed end 9211, which can not only enable the sealed end 9211 to be in close contact with the inclined sealing surface 1211, but also reduce the probability of the sealing block 921 getting stuck inside the inner liquid outlet 121 when the sealing block 921 is pushed and moved by the push rod 86, making the opening of the liquid outlet channel 912 smoother.

[0277] Optionally, in one embodiment, as Figure 36 shown, a positioning groove 9212 is provided on the end surface of the sealing block 921 facing the liquid outlet channel 912, and the positioning groove 9212 is used for the push rod 86 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 86 for pushing open the sealing block 921. For example, when the push rod 86 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 86, so that the push rod 86 can just penetrate into the positioning groove 9212. It can be understood that by setting the positioning groove 9212 to position the push rod 86, the large relative sliding between the push rod 86 and the sealing block 921 during the process of pushing the sealing block 921 can be avoided, ensuring that the push rod 86 can stably push open the sealing block 921.

[0278] Optionally, in one embodiment, as Figure 35 or Figure 36 shown, a liquid storage groove 9213 is provided on the end surface of the sealing block 921 facing away from the liquid outlet channel 912, and the liquid storage groove 9213 is used for storing the atomization 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, enabling the liquid cup 20 to store more atomization liquid, but also reduce the weight of the sealing block 921, making the entire liquid cup 20 lighter.

[0279] It should be noted here that when the user uses the aerosol generating device 500, the entire aerosol generating device 500 is in a nearly horizontal state, so the atomization liquid in the liquid storage groove 9213 can flow out and reach the liquid outlet channel 912. Of course, in order to prevent the atomization liquid from staying in the liquid storage groove 9213, liquid outlet small holes can be opened on the side wall of the liquid storage groove 9213 so that the atomization liquid in the liquid storage groove 9213 can flow out and reach the liquid outlet channel 912.

[0280] Optionally, in one embodiment, as Figure 33As shown, the liquid outlet channel 912 has an outer liquid outlet 122 which is in communication with the outside of the liquid cup 20. An installation groove 1221 is provided at the outer liquid outlet 122. Please also refer to Figure 10 , a liquid absorption member 28 is installed in the installation groove 1221. The liquid absorption member 28 can be liquid absorption cotton, liquid absorption ceramics, etc. The liquid absorption member 28 is used to adsorb the atomized liquid. When the atomization cartridge 300 is installed on the atomization assembly 100, the liquid absorption member 28 abuts against the heating element 82 on the atomization assembly 100, so that the heating element 82 can heat the atomized liquid on the liquid absorption member 28 to atomize the atomized liquid into aerosol. And in this embodiment, the liquid absorption member 28 is provided with a through hole 281 communicating with the liquid outlet channel 912. The through hole 281 is used for the push rod 86 to extend into and push open the sealing block 921, so that it is convenient for the push rod 86 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.

[0281] 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 an inner liquid outlet 121 and an outer liquid outlet 122 which are opposite to each other. The inner liquid outlet 121 is in communication with the liquid storage cavity 251, and the outer liquid outlet 122 is in communication with the outside of the liquid cup 20. A liquid absorption member 28 is further provided at the outer liquid outlet 122, and the liquid absorption member 28 is used to adsorb the atomized liquid.

[0282] 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 absorption member 28 is provided at the outer liquid outlet 122 of the liquid outlet channel 912. The liquid absorption member 28 can be liquid absorption cotton, liquid absorption ceramics, etc. The liquid absorption member 28 can absorb the atomized liquid from the liquid outlet channel 912, and the liquid absorption member 28 can lock the atomized liquid, so as to avoid the leakage of the atomized liquid from the liquid outlet channel 912.
