Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.

[0046] The aerosol generating device provided by the application is used for heating and atomizing the atomized substrate to generate corresponding aerosol. By arranging the connecting seat at the end of the atomizing device of the aerosol generating device away from the mouthpiece, and arranging the cavity seal at the connecting position of the atomizing device and the connecting seat, a plurality of mounting protrusions are asymmetrically arranged at the end of the cavity seal facing the connecting seat, a plurality of mounting slots are correspondingly arranged at the end of the connecting seat facing the cavity seal, the mounting slots are matched with the mounting protrusions in shape, and each mounting protrusion is inserted into a corresponding mounting slot. When assembling, the mounting protrusions and the mounting slots must be one-to-one matched to complete the assembly, so as to prevent misassembly.

[0047] Some embodiments of the aerosol generating device and the cavity seal provided by the application are described below with reference to the accompanying drawings.

[0048] In the embodiments of the first aspect of the application, an aerosol generating device 100 is provided, as shown in Figure 1 Figure 2 and Figure 3 The aerosol generating device 100 includes an atomizing device 1, a power supply device 2, and a connecting seat 3. The atomizing device 1 is used for heating and atomizing the atomized substrate to generate corresponding aerosol. In a first direction, the atomizing device 1 has a mouthpiece 11 at one end, and the aerosol generated inside the atomizing device 1 can be sucked out through the mouthpiece 11. The connecting seat 3 is arranged at the end of the atomizing device 1 away from the mouthpiece 11, and the end of the connecting seat 3 away from the atomizing device 1 is detachably connected with the power supply device 2, so as to realize the connection and assembly of the atomizing device 1 and the power supply device 2 through the connecting seat 3. The end of the atomizing device 1 connected with the connecting seat 3 has a cavity seal 12 for sealing the internal cavity of the atomizing device 1. The end of the cavity seal 12 facing the connecting seat 3 has a plurality of mounting protrusions 121, and the plurality of mounting protrusions 121 are asymmetrically arranged in a second direction perpendicular to the first direction. Correspondingly, the end of the connecting seat 3 facing the atomizing device 1 has a plurality of mounting slots 31, the mounting slots 31 are correspondingly arranged with the mounting protrusions 121, and the shape of each mounting slot 31 is matched with a corresponding mounting protrusion 121. The mounting protrusions 121 are inserted into the corresponding mounting slots 31 in the first direction, so as to realize the alignment and cooperation of the cavity seal 12 and the connecting seat 3. After the overall assembly is completed, the power supply device 2 is electrically connected with the atomizing device 1, so as to supply power to the atomizing device 1 through the power supply device 2.

[0049] ​It should be noted that the number of mounting protrusions 121 in the embodiment can be one or more, and the number of mounting slots 31 matches the number of mounting protrusions 121; the shape of the mounting protrusion 121 includes but is not limited to a cylindrical shape, a square prism, a multi-prism, or other shapes, which can be set according to actual assembly needs, and can facilitate plug-in assembly, and the shape of the mounting slot 31 is adapted to the corresponding mounting protrusion 121.

[0050] In addition, in actual application, different shapes of mounting protrusions can be used to achieve asymmetric arrangement of multiple mounting protrusions, and of course the same shape of mounting protrusion can also be used, and asymmetric arrangement can be achieved by setting different positions, angles, etc. The aerosol generating device is not limited to the cylindrical structure shown in the embodiment, and other structure forms can also be set according to the use requirements. Figure 1

[0051] It can be understood that the common aerosol generating device is usually an assembled structure, and different structural components need to be assembled and connected, for example, the assembly and connection between the atomizing device 1, the connecting seat 3 and the power supply device 2 in the embodiment. During assembly, the positions, directions and angles of the structural components need to meet the design requirements, and accurate alignment is required for correct assembly and connection. However, during manual assembly operation, the operator needs to identify the assembly position, direction and angle of the components, which requires a certain amount of time and effort, and once the identification is incorrect, it may cause assembly errors and affect the normal progress of subsequent processes, especially in batch production, which affects the further improvement of production efficiency.

[0052] The aerosol generating device 100 in the embodiment is provided with a plurality of mounting protrusions 121 and a plurality of mounting slots 31 at the positions where the cavity seal 12 of the atomizing device 1 and the connecting seat 3 are assembled with each other, and the mounting protrusions 121 and the mounting slots 31 must be one-to-one corresponding for assembly by using asymmetric arrangement, so as to play a foolproof prompting role, so that the operator can quickly identify the correct assembly position, direction and angle, prevent assembly misalignment from affecting subsequent processes, and greatly reduce the time spent by the operator in identifying and distinguishing. It is beneficial to improve the working efficiency of processing and assembly.

[0053] In further embodiments of the present application, as Figure 2 , Figure 3 ​As shown, among the plurality of mounting protrusions 121 of the cavity sealing piece 12, the shape of at least one mounting protrusion 121 is different from the shape of other mounting protrusions 121, and correspondingly, the shape of at least one mounting slot 31 is matched therewith. Through the above arrangement, the recognizability can be improved by using mounting protrusions 121 of different shapes and corresponding mounting slots 31, which is beneficial to reduce the identification difficulty of the operator and reduce the time required by the operator to identify, thereby improving the efficiency of the assembly operation.

[0054] It can be understood that if the mounting protrusions 121 all adopt the structure of the same shape, even if there are differences in the assembly position, angle, etc., the recognizability for the operator is relatively low compared with the mounting protrusions 121 of different shapes, and according to common sense, the greater the shape difference between different components, the easier it is to be accurately identified. Therefore, the use of mounting protrusions 121 of different shapes in the embodiment can effectively improve the recognizability.

[0055] Further, as shown in Figure 4 and Figure 5 , on the cavity sealing piece 12, the plurality of mounting protrusions 121 specifically includes first protrusions 122 and second protrusions 123 of different shapes. In the second direction, the first protrusions 122 and the second protrusions 123 are arranged on both sides of the center line of the atomization device 1 in the first direction, so as to reserve enough space for assembly operation and other structures. Correspondingly, as shown in Figure 6 , the plurality of mounting slots 31 of the connecting seat 3 specifically includes first slots 311 and second slots 312 of different shapes, and the first slots 311 and the second slots 312 are also arranged in the second direction. Among them, as an example in Figures 5 to 7 , the shape of the first slot 311 is matched with the first protrusion 122 and is arranged correspondingly with the first protrusion 122, and the first protrusion 122 is inserted into the first slot 311; the shape of the second slot 312 is matched with the second protrusion 123 and is arranged correspondingly with the second protrusion 123, and the second protrusion 123 is inserted into the second slot 312. During the assembly operation, one-to-one correspondence must be performed to complete the plug-in assembly, that is, the first protrusion 122 must be aligned with the first slot 311, and the second protrusion 123 must be aligned with the second slot 312, so as to realize plug-in cooperation, otherwise mutual interference will occur, and the cavity sealing piece 12 and the connecting seat 3 cannot be assembled and connected.

[0056] Further, in a specific example, as shown in Figure 5 and Figure 6In the example shown in FIG. 12, the size of the first protrusion 122 in the second direction is smaller than the size of the second protrusion 123 in the second direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the second direction. The size relationship of the first slot 311 and the second slot 312 in the second direction is adapted to the first protrusion 122 and the second protrusion 123.

[0057] In another specific example, as shown in FIG. 13, the third direction is perpendicular to the first direction and perpendicular to the second direction; the size of the first protrusion 122 in the third direction is larger than the size of the second protrusion 123 in the third direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the third direction. The size relationship of the first slot 311 and the second slot 312 in the third direction is adapted to the first protrusion 122 and the second protrusion 123. Figure 5 Figure 6 In another specific example, as shown in FIG. 13, the third direction is perpendicular to the first direction and perpendicular to the second direction; the size of the first protrusion 122 in the third direction is larger than the size of the second protrusion 123 in the third direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the third direction. The size relationship of the first slot 311 and the second slot 312 in the third direction is adapted to the first protrusion 122 and the second protrusion 123.

[0058] In another specific example, as shown in FIG. 13, the third direction is perpendicular to the first direction and perpendicular to the second direction; the size of the first protrusion 122 in the third direction is larger than the size of the second protrusion 123 in the third direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the third direction. The size relationship of the first slot 311 and the second slot 312 in the third direction is adapted to the first protrusion 122 and the second protrusion 123.

[0059] It should be noted that in actual applications, the above-mentioned several different size relationships can be combined with each other, i.e., the first protrusion 122 and the second protrusion 123 can simultaneously satisfy the above-mentioned multiple size relationships, which can further improve the distinguishability and be beneficial to further improve the assembly operation efficiency.

[0060] Further, as shown in the example of FIG. 14, in a feasible structure, the first protrusion 122 has a first arc surface 1221 protruding outward at one end thereof in the second direction away from the second protrusion 123, and correspondingly, the first protrusion 122 has a second arc surface 1222 concave inward at one end thereof in the second direction toward the second protrusion 123. Since the first protrusion 122 and the second protrusion 123 are respectively arranged on both sides of the center line of the atomization device 1, and the atomization device 1 usually adopts a cylindrical structure, the central position is generally used to set a circular hole structure (for example, a circular hole structure 2 is arranged in the center of the atomization device 1 in FIG. 14). Figure 5 Figure 6 In the example shown in FIG. 12, the size of the first protrusion 122 in the second direction is smaller than the size of the second protrusion 123 in the second direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the second direction. The size relationship of the first slot 311 and the second slot 312 in the second direction is adapted to the first protrusion 122 and the second protrusion 123. Figure 5 ​​As shown in the first air hole 124 in the first embodiment, by setting the first protrusion 122, the first protrusion 122 has the first arc surface 1221 and the second arc surface 1222 at both ends in the second direction, which can be effectively matched with the cavity seal 12 and the outer edge of the atomization device 1, and can be effectively matched with the circular hole structure at the center position, thereby improving the space utilization efficiency; at the same time, by setting the first arc surface 1221 and the second arc surface 1222, the recognizability of the first protrusion 122 can be further improved.

[0061] Further, as shown in the examples in Figure 5 and Figure 6 , in another possible structure, the second protrusion 123 has a concave third arc surface 1231 at least at one end in the third direction, and correspondingly, the second protrusion 123 has a concave fourth arc surface 1232 at one end in the second direction towards the first protrusion 122. Since the first protrusion 122 and the second protrusion 123 are respectively arranged on both sides of the center line of the atomization device 1, and the atomization device 1 usually adopts a cylindrical structure, the center position is generally used to set a circular hole structure (for example, the first air hole 124 shown in the first embodiment), by setting the fourth arc surface 1232, the fourth arc surface 1232 can be effectively matched with the circular hole structure at the center position; and by setting the concave third arc surface 1231 and the fourth arc surface 1232, when the second slot 312 is inserted and matched, the third arc surface 1231 and the fourth arc surface 1232 can also play a certain limiting role, and the recognizability of the second protrusion 123 can be further improved. Figure 5

[0062] It should be noted that the above examples related to the arc surface features can also be used in combination, that is, the first protrusion 122 has the first arc surface 1221 and the second arc surface 1222, and the second protrusion 123 has the third arc surface 1231 and the fourth arc surface 1232.

[0063] In further embodiments of the present application, as shown in Figure 8 , Figure 9 and Figure 10 , the aerosol generating device 100 further comprises an outer shell 42. The outer shell 42 corresponds to the mouthpiece 11, and the atomization device 1, the power supply device 2 and the connecting seat 3 are arranged inside the outer shell 42, the mouthpiece 11 is located outside the outer shell 42, and the end of the mouthpiece 11 towards the power supply device 2 is detachably connected to the outer shell 42 to support and protect the outer shell 42. Among them, the outer shell 42 has at least one opening 421 to communicate the inside and outside of the outer shell 42, and correspondingly, the power supply device 2 has an airway structure 23, and the airway structure 23 communicates with the opening 421 of the outer shell 42 and the atomization device 1, so that external gas can enter the atomization device 1 through the airway structure 23 to carry the aerosol generated by the atomization device 1 to the mouthpiece 11.

[0064] In further embodiments of the present application, as shown in​Figures 1 to 3 as well as Figure 10 As shown, the atomizing device 1 includes a liquid storage chamber 13 and an atomizing core assembly 14. The liquid storage chamber 13 has an internal cavity for containing the atomizing matrix. In a first direction, the end of the liquid storage chamber 13 facing the mouthpiece 11 is connected to the mouthpiece 11. The end of the liquid storage chamber 13 away from the mouthpiece 11 is a through structure and contains a cavity seal 12. The outer wall of the cavity seal 12 is sealed to the inner wall of the liquid storage chamber 13 to seal the atomizing matrix contained within the liquid storage chamber 13. The cavity seal 12 has a first vent hole 124 extending in the first direction. The atomizing core assembly 14 is disposed within the liquid storage chamber 13 and is used to heat the atomizing matrix to atomize it into an aerosol. Figure 11 and Figure 12 As shown, the inner wall of the liquid storage cavity 13 has a first snap-fit ​​structure 131, and the outer wall of the connecting seat 3 has a second snap-fit ​​structure 321 that matches the first snap-fit ​​structure 131. The second snap-fit ​​structure 321 engages with the corresponding first snap-fit ​​structure 131 to achieve the connection and assembly between the liquid storage cavity 13 and the connecting seat 3. When the user performs a suction action on the suction nozzle 11, the airflow can enter the ventilation pipe 142 through the first vent hole 124, and under the action of negative pressure, carry the generated aerosol to the suction nozzle 11.

[0065] In a specific example, such as Figure 10 In the example, the atomizing core assembly 14 specifically includes an intersecting ventilation pipe 142 and an atomizing core body 141. The ventilation pipe 142 extends along a first direction, with one end connected to the mouthpiece 11 and the other end connected to the first ventilation hole 124 of the cavity seal 12. The atomizing core body 141 passes laterally through the ventilation pipe 142 and extends into the cavity of the liquid storage chamber 13 for containing the atomizing matrix, so as to heat and atomize the atomizing matrix and allow the generated aerosol to enter the ventilation pipe 142 and flow towards the mouthpiece 11 with the airflow. The atomizing core body 141 has a conductive structure 1411, which passes through the cavity seal 12 and the connecting seat 3 and is electrically connected to the power supply device 2, so that the power supply device 2 supplies power to the atomizing core body 141, enabling the atomizing core body 141 to generate heat to heat the atomizing matrix.

[0066] To facilitate connection, a connector pipe section can be provided at the end of the first vent 124 away from the mounting protrusion 121, such as... Figure 7 and Figure 10 In the example, during assembly, the connector pipe section can extend into the vent pipe 142 so that the vent pipe 142 can be accurately aligned with the first vent hole 124, and can also play a sealing and limiting role.

[0067] It should be noted that the first clamping structure 131 and the second clamping structure 321 can adopt the structure form of a clamping protrusion and a clamping hole, for example Figure 2 and Figure 12 In the examples, the first clamping structure 131 specifically adopts the form of a clamping protrusion, and the second clamping structure 321 adopts the form of a clamping hole. When the connecting seat 3 is inserted into the liquid storage cavity 13, slight extrusion deformation is generated to make the clamping protrusion extend into the corresponding clamping hole to form clamping fixation. Of course, the clamping protrusion and the clamping hole can also be interchanged in position, and in addition, the clamping hole can also be replaced by a clamping groove. The number of the first clamping structure 131 can be one or more, and the number of the second clamping structure 321 matches that of the first clamping structure 131.

[0068] Further, as examples in Figure 13 and Figure 14 In the first direction, the end of the cavity seal 12 away from the suction nozzle 11 has a first assembly groove 125, the first assembly groove 125 is arranged along the circumference of the cavity seal 12, and the plurality of mounting protrusions 121 are all located inside the first assembly groove 125. Correspondingly, the end of the connecting seat 3 towards the suction nozzle 11 has a second assembly groove 33, the side wall of the second assembly groove 33 is arranged along the circumference of the connecting seat 3 and corresponds to the first assembly groove 125; a plurality of mounting slots 31 are located in the second assembly groove 33, and the second assembly groove 33 has a second air passage 331 penetrating in the first direction. The side wall of the second assembly groove 33 is inserted into the first assembly groove 125 in the first direction and abuts against the inner wall surface of the first assembly groove 125, so as to form a plug-in fit between the cavity seal 12 and the connecting seat 3. Among them, the second air passage 331 communicates with the first air passage 124, so that the airflow can flow to the atomizing core assembly 14 through the second air passage 331 and the first air passage 124.

[0069] Further, as examples in Figures 12 to 14 The outer side wall of the cavity seal 12 has a sealing protrusion 1261 arranged along the circumference, and the sealing protrusion 1261 abuts against the inner wall surface of the liquid storage cavity 13 to seal the contact surface between the cavity seal 12 and the liquid storage cavity 13. Among them, the cavity seal 12 specifically adopts a flexible structure with a certain elasticity, for example, a silica gel structure, which can form an interference fit between the cavity seal 12 and the liquid storage cavity 13 during assembly to enhance the sealing effect between the cavity seal 12 and the liquid storage cavity 13.

[0070] Further, as examples in Figure 2 , Figure 3 and Figure 10In the example shown in FIG. 13, one end of the pressure suction nozzle 11 on the side wall of the liquid storage cavity 13 has a first notch 132, which is circumferentially spaced apart from the first clamping structure 131; correspondingly, the outer side wall of the connecting seat 3 has a first protrusion 34, which is arranged corresponding to the first notch 132 and extends into the first notch 132 to form a plug-in fit. During assembly, the positions of the first notch 132 and the first protrusion 34 can further serve as a prompt; when the mounting protrusion 121 of the cavity seal 12 and the mounting slot 31 of the connecting seat 3 are not correctly aligned, the first protrusion 34 and the first notch 132 will also be positionally deviated, and cannot normally form a plug-in fit, so that the operator can quickly identify the correct assembly position and angle, thereby further improving the assembly operation efficiency. The number of first notches 132 can be one or more, and the number of first protrusions 34 matches the number of first notches 132.

[0071] Further, as shown in the example of FIG. 14, Figure 2 , Figure 3 , Figure 12 and Figure 13 , the power supply device 2 has a third assembly slot 211 at one end facing the atomization device 1, for connecting with the connecting seat 3. The inner side wall of the third assembly slot 211 has a third clamping structure 212, and the outer side wall of the connecting seat 3 has a fourth clamping structure 322 adapted to the third clamping structure 212; one end of the connecting seat 3 away from the suction nozzle 11 is inserted into the third assembly slot 211, and the fourth clamping structure 322 of the connecting seat 3 and the corresponding third clamping structure 212 form a clamping fit, so that the connecting seat 3 and the power supply device 2 are connected and fixed. The third clamping structure 212 and the fourth clamping structure 322 can adopt the structure form of a clamping protrusion and a clamping hole, for example, as shown in the example of FIG. 15, Figure 2 and Figure 12 , the fourth clamping structure 322 specifically adopts the form of a clamping protrusion, and the third clamping structure 212 adopts the form of a clamping hole, so that when the connecting seat 3 is assembled into the third assembly slot 211, it is slightly extruded and deformed, so that the clamping protrusion extends into the corresponding clamping hole to form a clamping fixation. Of course, the clamping protrusion and the clamping hole can also be interchanged in position, and the clamping hole can also be replaced by a clamping slot. The number of third clamping structures 212 can be one or more, and the number of fourth clamping structures 322 matches the number of third clamping structures 212.

[0072] In a specific example, as shown in FIG. 16, Figure 10 , Figures 12 to 14In the example of the power supply device 2, the power supply device 2 specifically comprises a power supply base 21, a power supply battery 221, and a controller 222. The power supply base 21 has a battery accommodating cavity, and the power supply battery 221 and the controller 222 are arranged in the battery accommodating cavity. The power supply base 21 is formed with a third assembly groove 211 at one end thereof in the first direction and towards the atomization device 1, and a third clamping structure 212 is arranged on the side wall of the power supply base 21. The third assembly groove 211 has a third air hole 224, so that the airflow can pass through the third air hole 224 into the third assembly groove 211, and then pass through the second air hole 331 and the first air hole 124 into the atomization core assembly 14. The controller 222 specifically can adopt the form of a circuit board, and corresponding control elements and circuits are arranged on the circuit board. The controller 222 is electrically connected with the power supply battery 221 and the atomization core body 141, so as to control the power supply state of the atomization core body 141. The controller 222 specifically can be provided with a corresponding conductive column 223, which penetrates into the third assembly groove 211 and is electrically connected with the conductive structure 1411 of the atomization core body 141 extending into the third assembly groove 211.

[0073] Further, as shown in the examples of Figure 10 、 Figure 13 and Figure 14 , the cavity seal 12 is provided with a first wire passing channel 1262, and the connecting seat 3 is provided with a second wire passing channel 35 corresponding to the first wire passing channel 1262. The conductive structure 1411 of the atomization core assembly 14 passes through the first wire passing channel 1262 and the second wire passing channel 35, and forms an electrical connection with the power supply device 2. For example, in a specific connection mode, as shown in the examples of Figure 10 、 Figure 13 and Figure 14 , the third assembly groove 211 of the power supply device 2 has a conductive column 223, and one end of the connecting seat 3 towards the power supply device 2 has a conductive slot 36 corresponding to the conductive column 223, and the conductive slot 36 is in communication with the second wire passing channel 35 in the second direction. During assembly, the connecting seat 3 and the atomization device 1 can be connected and assembled first, and then the conductive structure 1411 of the atomization core assembly 14 is passed out of the second wire passing channel 35, and then one end of the conductive structure 1411 passed out of the second wire passing channel 35 is bent to enter the conductive slot 36. Then, the connecting seat 3 and the power supply device 2 are connected and assembled, and the conductive column 223 of the power supply device 2 is inserted into the conductive slot 36 and is in extrusion assembly with the conductive structure 1411, so as to form an electrical connection between the conductive column 223 and the conductive structure 1411. The first wire passing channel 1262 can adopt a hole structure with sealing function, which can normally pass the conductive structure 1411 but the circumferential edge of the conductive structure 1411 is still in a sealed state, so as to prevent the atomization matrix from leaking. The second wire passing channel 35 can also have a similar hole structure, or directly adopt a through hole structure.

[0074] In further embodiments of the present application, as shown in Figure 10 and Figure 12 , the aerosol-generating apparatus 100 further comprises a mouthpiece plug 41. The mouthpiece plug 41 has an insertion section 411 which can be detachably inserted into the mouthpiece 11 to block the mouthpiece 11 in a non-use state to prevent dust and leakage. The outer side wall of the insertion section 411 has a protrusion structure 412 arranged circumferentially, so that when the insertion section 411 is inserted into the mouthpiece 11, the protrusion structure 412 can abut against the inner side wall of the mouthpiece 11 to enhance the sealing effect. Among them, the mouthpiece plug specifically adopts a flexible structure with a certain elasticity, such as a silica gel structure, which has better sealing effect and is also convenient for disassembly and assembly operations.

[0075] In embodiments of the second aspect of the present application, a cavity seal 12 is provided, as shown in Figure 2 , Figure 5 , Figure 6 , the cavity seal 12 can be applied to the atomization device 1 of the aerosol-generating apparatus 100 in any of the embodiments of the first aspect, and is assembled in the liquid storage cavity 13 of the atomization device 1 to seal. The cavity seal 12 has a plurality of mounting protrusions 121 at one end in a first direction, and the plurality of mounting protrusions 121 are arranged asymmetrically in a second direction perpendicular to the first direction, and at least one mounting protrusion 121 has a shape different from that of the other mounting protrusions 121. When the cavity seal 12 is applied to the aerosol-generating apparatus 100, the end of the cavity seal 12 provided with the mounting protrusions 121 is located away from the end of the mouthpiece 11 of the atomization device 1, and each mounting protrusion 121 is respectively inserted and matched with the corresponding mounting slot 31 on the connecting seat 3. When assembling, the mounting protrusions 121 must form one-to-one correspondence with the mounting slots 31, so that the atomization device 1 and the connecting seat 3 can be assembled and connected, otherwise the correct connection cannot be achieved, and the subsequent assembly process cannot be normally carried out, thereby playing a fool-proofing role. The operator can quickly identify the correct assembly position, direction, angle, etc. between the atomization device 1 and the connecting seat 3 through the mounting protrusions 121 and the mounting slots 31, thereby reducing the possibility of assembly errors and improving the efficiency of assembly operations.

[0076] In further embodiments of the present application, as shown in Figure 2 , Figure 4 and Figure 5 , on the cavity seal 12, the plurality of mounting protrusions 121 specifically include first protrusions 122 and second protrusions 123 which are different in shape.

[0077] Further, in a specific example, as shown in FIG. 12, the first protrusion 122 is provided with a first arc surface 1221, and the second protrusion 123 is provided with a second arc surface 1231, and the first arc surface 1221 and the second arc surface 1231 are arranged to be matched with each other. Figure 5 and Figure 6 In the example in FIG. 11, the size of the first protrusion 122 in the second direction is smaller than the size of the second protrusion 123 in the second direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the second direction.

[0078] In another specific example, as shown in FIG. 13, the third direction is perpendicular to the first direction and perpendicular to the second direction; the size of the first protrusion 122 in the third direction is greater than the size of the second protrusion 123 in the third direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the third direction. Figure 5 Figure 6 In another specific example, as shown in FIG. 13, the third direction is perpendicular to the first direction and perpendicular to the second direction; the size of the first protrusion 122 in the third direction is greater than the size of the second protrusion 123 in the third direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the third direction.

[0079] In yet another specific example, the size of the first protrusion 122 in the first direction can be different from the size of the second protrusion 123 in the first direction, so as to improve the distinguishability during the assembly operation by the difference in size of the first protrusion 122 and the second protrusion 123 in the first direction, and correspondingly, the depth size of the first slot 311 of the connecting seat 3 can be matched with the size of the first protrusion 122 of the cavity sealing element 12 in the first direction, and the depth size of the second slot 312 of the connecting seat 3 can be matched with the size of the second protrusion 123 of the cavity sealing element 12 in the first direction.

[0081] Further, as shown in the examples in Figure 5 and Figure 6 , in another possible structure, the second protrusion 123 has a concave third arc surface 1231 at at least one end in the third direction, and correspondingly, the second protrusion 123 has a concave fourth arc surface 1232 at one end in the second direction towards the first protrusion 122. By setting the fourth arc surface 1232, the circular hole structure at the center position can be effectively fitted; and by setting the concave third arc surface 1231 and the fourth arc surface 1232, a certain limiting effect can be achieved when the second slot 312 is inserted and matched, and the recognizability of the second protrusion 123 can be further improved.

The cavity seal 12 can adopt a flexible structure with a certain elasticity, such as a silica gel structure, which can form an interference fit between the cavity seal 12 and the liquid storage cavity 13 during assembly to enhance the sealing effect between the cavity seal 12 and the liquid storage cavity 13.

When the cavity seal 12 is applied to the aerosol generating device 100, the first assembly groove 125 can be inserted and matched with the second assembly groove 33 of the connecting seat 3 to serve as a connection and limiting effect.

[0084] Further, as shown in the examples in Figure 4 , Figure 7 and Figure 10In the example shown in the figure, the cavity seal 12 also has a first air hole 124 through in the first direction, so that when the cavity seal 12 is assembled with the liquid storage cavity 13 of the atomization device 1, the first air hole 124 can be communicated with the atomization device 1 to allow gas to flow into the air passage 142. In order to facilitate connection, the first air hole 124 can have a joint pipe section at the end away from the mounting protrusion 121, and when assembled, the joint pipe section can extend into the air passage 142 to accurately align the air passage 142 with the first air hole 124, and also to seal and limit.
