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

[0036] In the description of the embodiments of the present utility model, the orientation or position relationship of the "first direction" is based on the attached Figure 2 , Figure 4 , Figure 6 , Fig. 9 and Fig.11 The orientation or position relationship shown in the “second direction” is based on the Figure 8 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the embodiments of the utility model and simplifying the description, rather than indicating or implying 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 utility model.

[0037] The present invention provides an aerosol generating device for generating aerosol for a user to inhale. Figures 1 to 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 substrate and atomize the aerosol generating substrate to form an aerosol for the user to inhale by heating or other means.

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

[0040] It should be noted that the relevant structure and principles of the atomizer core contacting the aerosol-generating substrate and atomizing it have been applied in the relevant technology 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, such as a lithium battery.

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

[0048] Or the bracket assembly 21 is provided with an installation space 211a, and the battery 23 is arranged in the installation space 211a. The installation space provides an installation position for the battery 23 and plays a certain protective role. The connecting hole 21a extends along the first direction, and the conductive member 22 is penetrated in the connecting hole 21a and electrically connected to the battery 23.

[0049] The specific form of the 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 a control circuit board and electrically connected, and the control circuit board may be connected to the positive and negative electrodes of the battery 23 and electrically connected, so as to regulate the voltage and current output by the battery 23 to the conductive member 22 through the control circuit board.

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

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

[0053] When at least part 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 utility model inserts the conductive column 11 into the connecting hole 21a and abuts against the conductive member 22 located in the connecting hole 21a. While realizing the electrical connection between the conductive column 11 and the conductive member 22 to provide the power supply assembly 20 with electric energy to the atomizer 10, the friction between the conductive column 11 and the conductive member 22 and between the conductive member 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 member 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 members to maintain the relative position between the conductive column 11 and the conductive member 22, and there is no need to set up additional electrical connectors to realize the electrical connection between the atomizer 10 and the power supply assembly 20, which is conducive 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 as to realize the replacement of the battery 23, the replenishment of the aerosol generating matrix and other operations 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 reduce the expected service life requirements of the components in the aerosol generating device and reduce 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 member 22 can enter the gap between the two, thereby achieving the purpose of at least part of the conductive member 22 being clamped between the inner wall of the connecting hole 21a and the conductive column 11 perpendicular to the first direction, thereby reducing the probability of pushing the conductive member 22 along the first direction during the process of inserting the conductive column 11 into the connecting hole 21a and failing to clamp the conductive member 22 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 connecting holes 21 a is not limited, and may be one or more.

[0058] For example, see Figures 2 to 5 The number of the conductive column 11, the connecting hole 21a and the conductive member 22 are all two, and the three are configured in a one-to-one correspondence. One conductive column 11 and one conductive member 22 are both electrically connected to the positive electrode of the battery 23, and the other conductive column 11 and the other conductive member 22 are both electrically connected to the negative electrode of the battery 23, so as to form a conductive loop.

[0059] The conductive column 11 may completely pass through the connecting hole 21a, that is, one end of the conductive column 11 close to the power supply assembly 20 along the first direction passes through the connecting hole 21a and is away from the opening of the atomizer 10 along the first direction; alternatively, one 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, see Figures 2 to 8 The conductive member 22 is provided with a conductive through hole 221a penetrating along the first direction, and the conductive column 11 is penetrated in the conductive through hole 221a. The conductive column 11 and the inner wall of the conductive through hole 221a are in interference fit.

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

[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 it is difficult for the conductive pillar 11 to be inserted into the conductive through hole 221 a .

[0064] In some embodiments, see Figure 3 , Figure 5 , Figures 6 to 8 The conductive member 22 is provided with a deformation groove 221b, and the deformation groove 221b connects the conductive through hole 221a and the outside of the conductive member 22 along the second direction. The first direction is orthogonal to the second direction.

[0065] By setting the deformation groove 221b, the structural strength of the conductive member 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 to thereby expand the conductive through hole 221a. While facilitating the insertion of the conductive column 11 into the conductive through hole 221a, the conductive member 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 member 22.

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

[0067] In some embodiments, see 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, and the cylindrical portion 221 is sandwiched between the inner wall of the connecting hole 21a and the conductive column 11. That is, the cylindrical portion 221 is inserted into the connecting hole 21a, and the conductive column 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 increase the contact surface between the conductive column 11 and the conductive member 22, which is beneficial to improve the friction between the two, and is more beneficial to keep 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 improve the friction between the two and further beneficial to keep the relative position between the two stable.

[0070] Thus, 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 via 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-sectional shape of the conductive through hole 221a perpendicular to the first direction and the cross-sectional shape 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 and damage to both during the process of inserting the conductive column 11 into the conductive through hole 221a.

[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 and damage to the cylindrical portion during the insertion of the conductive column 11 into the conductive through hole 221a.

[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 a rotation axis to form the cylindrical portion 221, and deformation grooves 221b are formed at intervals along the circumferential direction 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 the original shape.

[0078] In some embodiments, see Figures 6 to 8 The conductive member 22 further includes a connecting piece 222, and the connecting piece 222 is electrically connected to the battery 23. That is, the connecting piece 222 is electrically connected to the cylindrical portion 221, so that the current can be transmitted from the battery 23 to the cylindrical portion 221 through 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, thereby reducing the assembly precision requirements and improving 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, see Figures 6 to 8 The cylindrical portion 221 is located in the communicating 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 communicating 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, see Figure 5 and Figure 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 11a. The positioning protrusion 223 and the positioning groove 11a cooperate with each other to make the conductive member 22 and the conductive column 11 stop and cooperate.

[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 column 11 and the conductive member 22 are stopped and matched along the first direction to limit the tendency of relative movement between the conductive column 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 difficulty of assembly and improving the efficiency of assembly.

[0086] The specific number of the positioning protrusions 223 is not limited, and can be one or more. In the 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 an axis, so that the force between the conductive column 11 and the conductive member 22 is uniform, and the relative position stability between the two is better maintained.

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

[0088] For example, in the embodiment where the positioning protrusion 223 is located on the conductive member 22, see Figure 6 The conductive member 22 is made of copper, and a positioning protrusion 223 is formed on the other side of the conductive member 22 by stamping the side 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] See also Figure 6 and Figure 8 In the embodiment with the cylindrical portion 221, the positioning protrusion 223 is located on the inner wall of the conductive through hole 221a, so that the conductive member 22 can directly achieve the matching between the positioning protrusion 223 and the positioning groove 11a during the insertion of the conductive through hole 221a, thereby simplifying the assembly steps.

[0090] It can be 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, see 5. Figure 7 and Figure 8 The conductive member 22 includes a deformation portion 22b, which can be elastically deformed so that the deformation portion 22b abuts against the inner wall of the connecting hole 21a.

[0092] In this way, the friction force generated by the abutment between the deformable portion 22 b and the inner wall of the connecting hole 21 a suppresses the tendency of 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, see 5. Figure 7 and Figure 8 The conductive member 22 is provided with a stop spring 224, the first end 2241 of the stop spring 224 along the first direction is connected to the conductive member 22, and the second end 2242 along the first direction is separated from the conductive member 22, and the stop spring 224 can be elastically deformed so that the stop spring 224 abuts against the inner wall of the connecting hole. In other words, the stop spring 224 forms the deformation portion 22b.

[0095] The second end 2242 is located at 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 to enable 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 column 11, the inner wall of the connecting hole 21a squeezes the stop spring 224, and the distance between the second end 2242 and the first end 2241 perpendicular to the first direction is smaller than that when the conductive member 22 is not sandwiched between the inner wall of the connecting hole 21a and the conductive column 11, so that elastic potential energy is accumulated in the stop spring 224. Driven by the elastic potential energy, the second end 2242 has a tendency to move toward the inner wall of the connecting hole 21a, so that the second end 2242 maintains 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 between the inner wall of the connecting hole 21a and the second end 2242 perpendicular to the first direction 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 stop spring pieces 224 is not limited, and may be one or more.

[0099] It can be understood 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] For example, see Figure 5 The second end 2242 is located at 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 to the atomizer 10 During the process of inserting the opening of one end of the connecting hole 21a 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, see Figure 7 The conductive member 22 is provided with a receiving hole 22a penetrating perpendicularly to the first direction, and the first end 2241 is connected to the inner wall of the receiving hole 22a.

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

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

[0107] In some embodiments with a cylindrical portion 221, see Figure 7 , the stopping spring piece 224 is located at the cylindrical portion 221 .

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

[0109] In some embodiments, see Figure 5 , Figure 6 and Figure 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 assembly 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 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 and causing risks such as a short circuit between the two, and at the same time, it can block the user's line of sight.

[0111] See also Figure 8 The shielding 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 shielding piece 225 along the first direction, thereby helping to reduce the manufacturing difficulty of the shielding piece 225; or, the shielding piece 225 is sealed and fitted with the inner wall of the connecting hole 21a to isolate the spaces on both sides of the shielding piece 225 along the first direction from each other, thereby improving the shielding effect of the shielding piece 225 on foreign objects of various sizes.

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

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

[0114] In some embodiments, see Figure 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 the 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 partially positioning the connecting hole 21a on the supporting column 2122, it is helpful to reduce the size of the other parts of the bracket assembly 21 near the end of the atomizer 10 along the first direction, which is helpful to make the structure of the bracket assembly 21 more compact; on the other hand, by the abutment between the supporting 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, see Figure 3 , Fig. 9 and Fig.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 penetrates 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 penetrated in 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 position for the battery 23 , but also plays a certain protective role 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, interference from components such as the inner wall of the installation space 211a and the battery 23 is reduced, providing a larger operating space, making it easier for personnel or machinery to operate, and thus helping to improve assembly efficiency.

[0121] In some embodiments, see Figure 3 and Fig.10 The mounting seat 212 is provided with a stop surface 212a, 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, thereby reducing the probability of relative movement between the two and causing adverse effects on 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 to reduce the probability that the mounting seat 212 moves along the first direction during the insertion of 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, thereby 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, see Figure 3 and Fig.11 The mounting seat 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 penetrated into the mounting hole 211b. A stop surface 212a is formed on one side surface of the stop plate 2121 close to the battery 23. 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 stop 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 supporting 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] See also Fig. 9 and Fig.11 The cross-sectional shape of the mounting column 2123 perpendicular to the first direction and the cross-sectional shape of the mounting hole 211b perpendicular to the first direction are both circular, so as to reduce the probability of damage due to stress concentration.

[0129] In some embodiments, see Fig.11At least part 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 the direction away from the atomizer 10, so as to improve the structural strength of the support column 2122 and reduce the probability that the support column 2122 is deformed by the pressure of the atomizer 10 and the connecting hole 21a is twisted.

[0130] It can be understood that the number of the support columns 2122, the mounting columns 2123 and the communication holes 21a is the same, and the three correspond to each other, and each support column 2122 and each mounting column 2123 are located on the same stop plate 2121. Each support column 2122 and each mounting column 2123 are connected by the stop plate 2121, so that the relative position between each support column 2122 and each mounting column 2123 is fixed.

[0131] In some embodiments with multiple support columns 2122, see Fig.11 The mounting base 212 also includes a reinforcing rib 2124, which is connected between at least two support columns 2122, so as to suppress the probability of the support columns 2122 being twisted and deformed under the pressure of the atomizer 10 through the reinforcing rib 2124, thereby improving the overall structural strength of the mounting base 212.
