[0035] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present disclosure may be combined with each other, and the detailed description in the specific implementation manner should be understood as an explanation of the purpose of the embodiments of the present disclosure and should not be regarded as an improper limitation on the embodiments of the present disclosure.

[0036] In the description of the embodiments of the present disclosure, the "first direction" orientation or position relationship is based on the orientation or position relationship shown in Figures 2, 4, 6, 9 and 11, and the "second direction" orientation or position relationship is based on the orientation or position relationship shown in Figure 8. It should be understood that these orientation terms are only for the convenience of describing the embodiments of the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present disclosure.

[0037] An embodiment of the present disclosure provides an aerosol generating device for generating aerosol for inhalation by a user. Referring to FIG. 1 to FIG. 5 , the aerosol generating device includes an atomizer 10 and a power supply assembly 20 .

[0038] The atomizer 10 is provided with an atomizing core, which can contact the aerosol-generating matrix and atomize the aerosol-generating matrix to form an aerosol for the user to inhale by heating or other means.

[0039] The aerosol generating substrate may be stored in the nebulizer 10 or in other components of the aerosol generating device.

[0040] It should be noted that the relevant structure and principles of the atomizing core contacting the aerosol-generating substrate and atomizing it have been applied in related technologies and will not be elaborated here.

[0041] The atomizer 10 is provided with a conductive column 11, which is used to contact the atomizer core and supply power to the atomizer core so that the atomizer core can use the electrical energy to atomize the aerosol-generating matrix to form an aerosol.

[0042] It is understandable that at least a portion of the conductive pillar 11 is made of a conductive material, and the specific type of the conductive material is not limited, such as copper.

[0043] The power supply assembly 20 is used to provide electrical energy to other electrical components in the aerosol generating device.

[0044] The power supply assembly 20 includes a bracket assembly 21 , a conductive member 22 and a battery 23 .

[0045] The battery 23 is used as a power source for the aerosol generating device.

[0046] The specific type of the battery 23 is not limited, for example, a lithium battery.

[0047] The bracket assembly 21 is provided with a communication hole 21 a , and the conductive member 22 is passed through the communication hole 21 a and is electrically connected to the battery 23 ;

[0048] Alternatively, the bracket assembly 21 defines a mounting space 211a, in which the battery 23 is located. The mounting space 211a provides a mounting location for the battery 23 and provides some protection. The connecting hole 21a extends along a first direction, and the conductive member 22 is disposed in the connecting hole 21a and electrically connected to the battery 23.

[0049] The specific form of electrical connection between the conductive member 22 and the battery 23 is not limited. The conductive member 22 may be in direct contact with the positive and negative electrodes of the battery 23; or the conductive member 22 may be connected to the control circuit board and electrically conductive, and the control circuit board may be connected to the positive and negative electrodes of the battery 23 and electrically conductive, so that the voltage and current output by the battery 23 to the conductive member 22 can be regulated by the control circuit board.

[0050] It is understood that at least a portion of the conductive member 22 is made of a conductive material, and the specific type of the conductive material is not limited, such as copper.

[0051] The conductive pillar 11 is inserted into the communicating hole 21 a so that at least a portion of the conductive member 22 is sandwiched between the inner wall of the communicating hole 21 a and the conductive pillar 11 , and the conductive member 22 is electrically connected to the conductive pillar 11 .

[0052] That is to say, after the conductive column 11 is inserted into the connecting hole 21a, at least part of the conductive part 22 is located between the inner wall of the connecting hole 21a and the conductive column 11 and fits with both, so that the conductive part 22 is subjected to the squeezing force from the inner wall of the connecting hole 21a and the conductive column 11. On the one hand, the friction between the conductive column 11 and the conductive part 22, and between the conductive part 22 and the inner wall of the connecting hole 21a is increased; on the other hand, the relative movement between the conductive column 11 and the conductive part 22 is restricted.

[0053] When at least a portion of the conductive member 22 is sandwiched between the inner wall of the connecting hole 21a and the conductive column 11, the relative positions of the atomizer 10 and the power supply assembly 20 also remain stable, and a conductive loop is formed between the battery 23, the conductive member 22 and the conductive column 11, so that the power supply assembly 20 can supply power to the atomizer 10.

[0054] The embodiment of the present disclosure inserts the conductive column 11 into the connecting hole 21a and abuts against the conductive part 22 located in the connecting hole 21a. While achieving electrical connection between the conductive column 11 and the conductive part 22 to provide electrical energy from the power supply assembly 20 to the atomizer 10, the friction between the conductive column 11 and the conductive part 22 and between the conductive part 22 and the inner wall of the connecting hole 21a is increased, thereby suppressing the tendency of relative movement between the three along the first direction, thereby facilitating the relative position between the conductive column 11 and the conductive part 22 to remain stable, and facilitating the stability of the electrical connection between the two. There is no need to set up additional connecting structural parts to maintain the relative position between the conductive column 11 and the conductive part 22, nor is there any need to set up additional electrical connectors to achieve electrical connection between the atomizer 10 and the power supply assembly 20, which is beneficial to reducing the number of components in the aerosol generating device, reducing assembly steps, and reducing production costs.

[0055] It can be understood that after the conductive column 11 is inserted into the connecting hole 21a, it can be pulled out again to achieve the purpose of replacing the atomizer 10, so that it is suitable for a detachable aerosol generating device, so that operations such as replacement of the battery 23 and replenishment of the aerosol generating matrix can be achieved in a detachable manner, thereby realizing the recycling of various components in the aerosol generating device; it can also no longer be pulled out, so that it is suitable for a disposable aerosol generating device, which is beneficial to reducing the expected service life requirements of the components in the aerosol generating device and reducing the number of components, thereby reducing the cost of the aerosol generating device.

[0056] It can be understood that there is a gap fit between the outer side surface of the conductive column 11 perpendicular to the first direction and the inner wall of the connecting hole 21a, so that the conductive part 22 can enter the gap between the two, thereby achieving the purpose of at least part of the conductive part 22 being clamped between the inner wall of the connecting hole 21a and the conductive column 11 perpendicular to the first direction, and reducing the probability of pushing the conductive part 22 along the first direction during the process of inserting the conductive column 11 into the connecting hole 21a and making it impossible for the conductive part 22 to be clamped between the conductive column 11 and the inner wall of the connecting hole 21a.

[0057] The specific number of the conductive pillars 11 , the conductive members 22 and the communication holes 21 a is not limited and can be one or more.

[0058] For example, referring to Figures 2 to 5, the number of conductive columns 11, connecting holes 21a and conductive parts 22 is two, and the three are configured in a one-to-one correspondence. One conductive column 11 and one conductive part 22 are both electrically connected to the positive pole of the battery 23, and the other conductive column 11 and the other conductive part 22 are both electrically connected to the negative pole of the battery 23 to form a conductive loop.

[0059] The conductive column 11 can completely pass through the connecting hole 21a, that is, the end of the conductive column 11 close to the power supply assembly 20 along the first direction passes through the connecting hole 21a and faces away from the opening of the atomizer 10 along the first direction; or the end of the conductive column 11 close to the power supply assembly 20 along the first direction is located in the connecting hole 21a.

[0060] It can be understood that the shape of the conductive member 22 should be conducive to improving its conductivity and connection stability.

[0061] In some embodiments, referring to FIG. 2 to FIG. 8 , the conductive member 22 is provided with a conductive through-hole 221 a extending along a first direction. The conductive column 11 is passed through the conductive through-hole 221 a , and an interference fit is formed between the conductive column 11 and the inner wall of the conductive through-hole 221 a .

[0062] This is beneficial for increasing the contact surface between the conductive pillar 11 and the conductive member 22 , improving the friction between the two, and maintaining a stable relative position between the two.

[0063] It is understandable that there is an interference fit between the inner wall of the conductive through hole 221 a and the conductive pillar 11 , and the conductive pillar 11 is difficult to insert into the conductive through hole 221 a .

[0064] In some embodiments, referring to FIG. 3 , FIG. 5 , and FIG. 6 to FIG. 8 , the conductive member 22 is provided with a deformation groove 221 b , which connects the conductive through hole 221 a and the exterior of the conductive member 22 along the second direction, and the first direction is orthogonal to the second direction.

[0065] By providing the deformation groove 221b, the structural strength of the conductive part 22 can be reduced, so that when the conductive column 11 is inserted into the conductive through-hole 221a, the gap of the deformation groove 221b can be enlarged, thereby expanding the conductive through-hole 221a. While facilitating the insertion of the conductive column 11 into the conductive through-hole 221a, the conductive part 22 can utilize the elastic contraction of its own material to maintain fit with the conductive column 11, thereby improving the connection stability between the conductive column 11 and the conductive part 22.

[0066] In some embodiments, referring to FIG. 6 , the deformation groove 221 b extends along the first direction to both ends of the conductive through hole 221 a , thereby facilitating adaptation to different insertion depths of the conductive pillar 11 in the conductive through hole 221 a .

[0067] In some embodiments, referring to Figures 2 to 8 , the conductive member 22 includes a cylindrical portion 221. The inner space of the cylindrical portion 221 forms a conductive through-hole 221a. The cylindrical portion 221 is sandwiched between the inner wall of the through-hole 21a and the conductive pillar 11. In other words, the cylindrical portion 221 is inserted into the through-hole 21a, and the conductive pillar 11 is inserted into the conductive through-hole 221a.

[0068] The conductive column 11 is inserted into the conductive through hole 221a, that is, the cylindrical portion 221 is arranged around the outer wall of the conductive column 11 perpendicular to the first direction, which is beneficial to increasing the contact surface between the conductive column 11 and the conductive member 22, which is beneficial to improving the friction between the two and more beneficial to maintaining the relative position between the two stable.

[0069] The cylindrical portion 221 is inserted into the connecting hole 21a, that is, the inner wall of the connecting hole 21a is arranged on the outer wall of the cylindrical portion 221 perpendicular to the first direction, which is beneficial to increase the contact surface between the inner wall of the connecting hole 21a and the conductive part 22, which is beneficial to increase the friction between the two and is more beneficial to maintain the relative position between the two stable.

[0070] In this way, by providing the cylindrical portion 221 on the conductive member 22 , it is more conducive to stabilizing the relative positions between the conductive column 11 and the conductive member 22 , and between the conductive member 22 and the inner wall of the connecting hole 21 a , which is conducive to stabilizing the electrical connection between the conductive column 11 and the conductive member 22 .

[0071] The cylindrical portion 221 is cylindrical.

[0072] It can be understood that the cross-sectional shape of the conductive through hole 221 a perpendicular to the first direction is the same as the cross-sectional shape of the conductive pillar 11 perpendicular to the first direction.

[0073] The specific shapes of the cross-section of the conductive through hole 221a perpendicular to the first direction and the cross-section of the conductive column 11 perpendicular to the first direction are not limited, for example, both are circular, so as to reduce the probability of stress concentration during the insertion of the conductive column 11 into the conductive through hole 221a and causing damage to both.

[0074] It can be understood that the cross-sectional shape of the outer surface of the cylindrical portion 221 perpendicular to the first direction is the same as the cross-sectional shape of the communicating hole 21 a perpendicular to the first direction.

[0075] The specific shapes of the cross-sectional shape of the outer surface of the cylindrical portion 221 perpendicular to the first direction and the cross-sectional shape of the connecting hole 21a perpendicular to the first direction are not limited, for example, both are circular, so as to reduce the probability of stress concentration during the insertion of the conductive column 11 into the conductive through hole 221a and causing damage to the cylindrical portion.

[0076] The specific manufacturing method of the cylindrical portion 221 is not limited. For example, the copper sheet is wound around a straight line extending along the first direction as the rotation axis to form the cylindrical portion 221, and deformation grooves 221b are formed at intervals along the circumference of the winding. The manufacturing process is simple and the manufacturing cost is low.

[0077] It is understandable that, since the cylindrical portion 221 is a hollow structure, the cylindrical portion 221 is easily deformed under the action of external shear force and is not easy to restore to its original shape.

[0078] In some embodiments, referring to Figures 6 to 8 , the conductive member 22 further includes a connecting piece 222 electrically connected to the battery 23. In other words, the connecting piece 222 is electrically connected to the cylindrical portion 221 so that current can be transferred from the battery 23 to the cylindrical portion 221 via the connecting piece 222.

[0079] The connecting piece 222 is a sheet-like structure, which can be easily bent along its thickness direction to achieve electrical connection with the battery 23, reducing the assembly precision requirements and helping to improve assembly efficiency; it prevents the battery 23 from directly contacting the cylindrical portion 221 and exerting force on the cylindrical portion 221, causing the cylindrical portion 221 to deform.

[0080] In some embodiments, referring to FIG. 6 to FIG. 8 , the cylindrical portion 221 is located in the communication hole 21 a , and the connecting piece 222 is disposed at one end of the cylindrical portion 221 close to the battery 23 and extends out of the communication hole 21 a to be electrically connected to the battery 23 .

[0081] The cylindrical portion 221 is completely located in the communicating hole 21 a , thereby shielding the cylindrical portion 221 and reducing the probability of deformation caused by collision between the cylindrical portion 221 and foreign objects during assembly.

[0082] In some embodiments, referring to FIG. 5 and FIG. 8 , one of the conductive member 22 and the conductive column 11 is provided with a positioning protrusion 223 , and the other is provided with a positioning groove 11 a . The positioning protrusion 223 and the positioning groove 11 a cooperate with each other to ensure that the conductive member 22 and the conductive column 11 are stopped and engaged.

[0083] In this way, the inner wall of the positioning groove 11a and the stopper cooperation between the positioning protrusion 223 limit the relative movement tendency between the conductive column 11 and the conductive member 22, so that the relative position of the two remains stable, which is conducive to maintaining the electrical connection between the two.

[0084] In some embodiments, the positioning protrusion 223 protrudes perpendicularly to the first direction, and the positioning groove 11a is open on one side perpendicular to the first direction, so that the conductive pillar 11 and the conductive member 22 are stopped and engaged along the first direction to limit the tendency of relative movement between the conductive pillar 11 and the conductive member 22 along the first direction.

[0085] In some embodiments, the positioning groove 11a is an annular groove with a straight line extending along the first direction as the rotation axis, so that during the assembly of the conductive column 11 and the conductive member 22, the positioning protrusion 223 can be accurately inserted into the positioning groove 11a, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0086] The specific number of the positioning protrusions 223 is not limited and can be one or more. In an embodiment where there are multiple positioning protrusions 223, the multiple positioning protrusions 223 are arranged circumferentially with a straight line extending along the first direction as the axis. This helps to ensure uniform force between the conductive pillar 11 and the conductive member 22, and better maintain the stability of the relative position between the two.

[0087] The specific method of forming the positioning protrusion 223 is not limited.

[0088] For example, in an embodiment where the positioning protrusion 223 is located on the conductive part 22, referring to FIG6, the material of the conductive part 22 is copper, and the positioning protrusion 223 is formed on the other side by stamping on the side of the conductive part 22 facing away from the conductive column 11, thereby utilizing the good ductility of copper to simplify the manufacturing process of the positioning protrusion 223 and improve production efficiency.

[0089] 6 and 8 , in an embodiment with a cylindrical portion 221 , the positioning protrusion 223 is located on the inner wall of the conductive through-hole 221 a so that the conductive member 22 can directly cooperate with the positioning protrusion 223 and the positioning groove 11 a during insertion into the conductive through-hole 221 a , thereby simplifying the assembly steps.

[0090] It is understood that it is necessary to suppress the relative movement between the inner wall of the communication hole 21 a and the conductive member 22 .

[0091] In some embodiments, referring to FIG5 , FIG7 and FIG8 , the conductive member 22 includes a deformable portion 22 b , which is capable of elastic deformation so as to abut against the inner wall of the communicating hole 21 a .

[0092] In this way, the friction force generated by the abutment between the deformable portion 22 b and the inner wall of the communicating hole 21 a suppresses the relative movement between the conductive member 22 and the bracket assembly 21 , thereby facilitating the improvement of the connection stability between the conductive member 22 and the conductive column 11 .

[0093] The specific method of forming the deformation portion 22b is not limited.

[0094] In some embodiments, referring to FIG5 , FIG7 , and FIG8 , the conductive member 22 is provided with a stopper spring 224 . The stopper spring 224 is connected to the conductive member 22 at a first end 2241 along the first direction and separated from the conductive member 22 at a second end 2242 along the first direction. The stopper spring 224 is elastically deformable so as to abut against the inner wall of the communication hole. In other words, the stopper spring 224 forms the deformable portion 22b.

[0095] The second end 2242 is located on a side of the first end 2241 close to the inner wall of the communicating hole 21a. In other words, the second end 2242 is used to abut against the inner wall of the communicating hole 21a.

[0096] The stop spring 224 undergoes elastic deformation, allowing the second end 2242 to move. When the conductive member 22 is sandwiched between the inner wall of the connecting hole 21a and the conductive post 11, the inner wall of the connecting hole 21a squeezes the stop spring 224, and the distance perpendicular to the first direction between the second end 2242 and the first end 2241 is smaller than when the conductive member 22 is not sandwiched between the inner wall of the connecting hole 21a and the conductive post 11. As a result, elastic potential energy accumulates in the stop spring 224. Driven by this elastic potential energy, the second end 2242 tends to move toward the inner wall of the connecting hole 21a, thereby maintaining contact with the inner wall of the connecting hole 21a.

[0097] On the one hand, under the action of elastic potential energy, the contact force perpendicular to the first direction between the inner wall of the connecting hole 21a and the second end 2242 is increased, thereby increasing the friction force between the two, which is beneficial to suppressing the relative movement between the inner wall of the connecting hole 21a and the conductive part 22; on the other hand, relative movement occurs between the inner wall of the connecting hole 21a and the conductive part 22, and under the action of elastic potential energy, the second end 2242 can scrape against the inner wall of the connecting hole 21a, or even insert into the inner wall of the connecting hole 21a, thereby suppressing the relative movement between the inner wall of the connecting hole 21a and the conductive part 22.

[0098] The specific number of the stopping springs 224 is not limited and can be one or more.

[0099] It will be appreciated that the relative positional relationship between the first end 2241 and the second section is related to the assembly relationship of the aerosol generating device.

[0100] Exemplarily, referring to FIG. 5 , the second end 2242 is located on a side of the first end 2241 away from the atomizer 10 along the first direction.

[0101] In this way, when the conductive member 22 is installed into the communicating hole 21a from the end opening of the communicating hole 21a away from the atomizer 10 along the first direction, the inner wall of the communicating hole 21a contacts the second end 2242 and exerts a friction force directed from the first end 2241 to the second end 2242, thereby reducing the scraping force between the second end 2242 and the inner wall of the communicating hole 21a, which is conducive to the installation of the conductive member 22 into the communicating hole 21a; and when the conductive column 11 is installed from the communicating hole 21a along the first direction toward the atomizer 10 During the process of inserting the opening of one end of the conductive column 11 into the connecting hole 21a, the conductive column 11 applies a force from the first end 2241 to the second end 2242 on the conductive member 22, so that the inner wall of the connecting hole 21a contacts the second end 2242 and applies a friction force from the second end 2242 to the first end 2241, thereby increasing the scraping force between the second end 2242 and the inner wall of the connecting hole 21a, thereby reducing the probability of the conductive member 22 moving along the first direction during the insertion of the conductive column 11.

[0102] In some embodiments, referring to FIG. 7 , the conductive member 22 defines a receiving hole 22 a extending perpendicularly to the first direction, and the first end 2241 is connected to an inner wall of the receiving hole 22 a .

[0103] In this way, when the stopping spring 224 is elastically deformed, the receiving hole 22a can accommodate at least a portion of the stopping spring 224, thereby facilitating reduction of the dimension of the conductive element 22 perpendicular to the first direction, making the structure of the conductive element 22 more compact.

[0104] In some embodiments, the accommodating hole 22a can completely accommodate the stop spring piece 224, thereby increasing the stroke of the second end 2242 perpendicular to the first direction, and then accumulating more elastic potential energy, thereby increasing the friction between the stop spring piece 224 and the inner wall of the connecting hole 21a, which is beneficial to the stability of the relative position between the conductive part 22 and the inner wall of the connecting hole 21a.

[0105] The specific method of forming the stop spring 224 is not limited.

[0106] Exemplarily, a partial area of ​​the conductive member 22 is punched out to separate a portion of the area from other portions to form the second end 2242 , thereby forming the stopping spring 224 .

[0107] In some embodiments with a cylindrical portion 221 , referring to FIG. 7 , the stop spring 224 is located in the cylindrical portion 221 .

[0108] It is understandable that during long-term use of the aerosol generating device, foreign matter may enter the communicating hole 21 a , thereby adversely affecting the electrical connection between the conductive member 22 and the conductive column 11 .

[0109] In some embodiments, referring to Figures 5, 6 and 8, the conductive member 22 is provided with a shielding piece 225, which is located in the connecting hole 21a. When the conductive column 11 is inserted into the connecting hole 21a, the shielding piece 225 is located between the opening of the connecting hole 21a on the side close to the battery 23 and the conductive column 11. The shielding piece 225 is used to cover at least part of the connecting hole 21a.

[0110] That is to say, one end of the conductive column 11 close to the power supply component 20 along the first direction is located in the connecting hole 21a, and the shielding piece 225 can block foreign matter from entering the connecting hole 21a from the opening on the side of the connecting hole 21a close to the battery 23, so as to reduce the probability of foreign matter entering the connection position between the conductive column 11 and the conductive part 22, causing a short circuit between the two, and at the same time, it can block the user's line of sight.

[0111] Referring to Figure 8, the blocking piece 225 is spaced apart from the inner wall of the connecting hole 21a to form a gap connecting the spaces on both sides of the blocking piece 225 along the first direction, which is conducive to reducing the manufacturing difficulty of the blocking piece 225; or, the blocking piece 225 is sealed and fitted with the inner wall of the connecting hole 21a to isolate the spaces on both sides of the blocking piece 225 along the first direction from each other, thereby improving the blocking effect of the blocking piece 225 on foreign objects of various sizes.

[0112] In some embodiments where a conductive through hole 221 a is provided, referring to FIG. 8 , the shielding piece 225 is located at an opening position of the conductive through hole 221 a at one end along the first direction.

[0113] In some embodiments where an accommodating hole 22a is provided, see FIG. 5 , the accommodating hole 22a is located between the opening of the communicating hole 21a close to the battery 23 and the accommodating hole 22a to reduce the probability of foreign matter entering the accommodating hole 22a and affecting the elastic deformation of the stop spring 224 .

[0114] In some embodiments, referring to FIG. 3 , a support column 2122 is provided at one end of the bracket assembly 21 close to the atomizer 10 . The support column 2122 extends along a first direction and abuts against the atomizer 10 along the first direction. At least a portion of the communication hole 21 a is located in the support column 2122 .

[0115] On the one hand, by at least part of the connecting hole 21a being located on the support column 2122, the size of the other parts of the bracket assembly 21 close to the end of the atomizer 10 along the first direction is reduced, which helps to make the structure of the bracket assembly 21 more compact; on the other hand, by the abutment between the support column 2122 and the atomizer 10, the insertion depth of the conductive column 11 in the connecting hole 21a can be limited, thereby reducing the probability that the conductive column 11 fails to achieve electrical connection with the conductive member 22 or is inserted too deeply, causing damage to other components in the power supply assembly 20.

[0116] The specific structure of the bracket assembly 21 is not limited.

[0117] For example, referring to Figures 3, 9 and 10, the bracket assembly 21 includes a mounting bracket 211 and a mounting seat 212. The mounting bracket 211 is provided with a mounting space 211a and a mounting hole 211b. The mounting hole 211b passes through the mounting bracket 211 along a first direction to connect the mounting space 211a and the outside of the mounting bracket 211. At least a portion of the mounting seat 212 is passed through the mounting hole 211b along the first direction, and the connecting hole 21a is provided in the mounting seat 212.

[0118] The battery 23 is disposed in the installation space 211 a . The installation space 211 a not only provides an installation location for the battery 23 , but also provides a certain degree of protection for the battery 23 .

[0119] During the assembly process, the conductive member 22 may be first installed into the communicating hole 21 a of the mounting seat 212 , and then the mounting seat 212 may be installed into the mounting hole 211 b .

[0120] In this way, during the process of installing the conductive member 22, the interference of the inner wall of the installation space 211a, the battery 23 and other components is reduced, and there is a larger operating space, which is convenient for personnel or machinery to operate and is conducive to improving assembly efficiency.

[0121] In some embodiments, referring to FIG. 3 and FIG. 10 , the mounting seat 212 has a stop surface 212 a , which is located on a side of the mounting bracket 211 close to the atomizer 10 along the first direction and cooperates with the mounting bracket 211 to stop along the first direction.

[0122] In this way, on the one hand, the relative position between the mounting seat 212 and the mounting bracket 211 along the first direction is constrained, reducing the probability of relative movement between the two and adversely affecting other components in the aerosol generating device; on the other hand, the mounting seat 212 can be supported by the mounting bracket 211 along the first direction, so as to reduce the probability that the mounting seat 212 moves along the first direction during the process of inserting the conductive column 11 into the connecting hole 21a, thereby reducing the probability that the conductive column 11 and the conductive member 22 cannot be electrically connected, and reducing the probability that the mounting seat 212 is deformed by force and damaged.

[0123] The specific structure of the mounting base 212 is not limited.

[0124] For example, referring to Figures 3 and 11, the mounting base 212 includes a stop plate 2121, a support column 2122 and a mounting column 2123. The support column 2122 is located on one side of the stop plate 2121 away from the battery 23 along the first direction, and the mounting column 2123 is located on the other side. The support column 2122 and the mounting column 2123 both extend along the first direction. The mounting column 2123 is passed through the mounting hole 211b. A stop surface 212a is formed on the surface of one side of the stop plate 2121 close to the battery 23, and the connecting hole 21a passes through the stop plate 2121, the support column 2122 and the mounting column 2123.

[0125] The mounting post 2123 is inserted into the mounting hole 211 b so that a stop fit is achieved between the surface of the mounting post 2123 and the inner wall of the mounting hole 211 b , thereby limiting the position of the mounting seat 212 perpendicular to the first direction.

[0126] The stop plate 2121 realizes the stopping cooperation between the mounting bracket 211 and the mounting seat 212, and can also shield the gap between the mounting column 2123 and the inner wall of the mounting hole 211b, thereby reducing the risk of foreign matter entering.

[0127] It can be understood that, in the projection plane perpendicular to the first direction, the projection of the mounting column 2123 and the projection of the support column 2122 are both located within the projection range of the stop plate 2121 , so that the surface of the stop plate 2121 forms a stop surface 212a .

[0128] 9 and 11 , the cross-sectional shape of the mounting post 2123 perpendicular to the first direction and the cross-sectional shape of the mounting hole 211 b perpendicular to the first direction are both circular to reduce the probability of damage due to stress concentration.

[0129] In some embodiments, referring to FIG. 11 , at least a portion of the outer side surface of the support column 2122 perpendicular to the first direction is a conical surface, and its cross-sectional area perpendicular to the first direction gradually increases in a direction away from the atomizer 10, so as to improve the structural strength of the support column 2122 and reduce the probability of the support column 2122 being deformed by the pressure of the atomizer 10, resulting in distortion of the connecting hole 21a.

[0130] It is understood that the number of support columns 2122, mounting columns 2123, and communication holes 21a is the same, and the three correspond one to one. Each support column 2122 and each mounting column 2123 are located on the same stop plate 2121. The stop plate 2121 connects each support column 2122 and each mounting column 2123, thereby fixing the relative position between each support column 2122 and each mounting column 2123.

[0131] In some embodiments having multiple support columns 2122 , referring to FIG. 11 , the mounting base 212 further includes reinforcing ribs 2124 , which are connected between at least two of the support columns 2122 . The reinforcing ribs 2124 suppress the possibility of the support columns 2122 being twisted and deformed under the pressure of the atomizer 10 , thereby improving the overall structural strength of the mounting base 212 .

[0132] The various embodiments / implementations of the present disclosure can be combined with each other unless any contradiction occurs.
