[0064] In related technologies, the atomizer in an aerosol generating device needs to be assembled and electrically connected to the aerosol generating host in a specific orientation. This assembly requires precise matching between the electrode components in the atomizer and the power supply components in the aerosol generating host, which increases the assembly difficulty and complexity to some extent, thus affecting assembly efficiency. In addition, incorrect assembly may lead to damage to the device to some extent.

[0065] To address the aforementioned issues, improve the assembly efficiency of the aerosol generating device 100, reduce assembly difficulty, and maintain the sealing performance of the aerosol generating device 100, this application provides an atomizer 10 and an aerosol generating device 100. By improving the structure of the atomizer 10, omnidirectional assembly of the atomizer 10 and the aerosol generating host 20 can be achieved.

[0066] Please see Figure 1 , Figure 2 and Figure 3 This application provides an aerosol generating device 100. Figure 1 This is a schematic diagram of the structure of the aerosol generating device 100 provided in the embodiments of this application. Figure 2 This is a cross-sectional structural schematic diagram of the aerosol generating device 100 provided in an embodiment of this application. Figure 3This is a schematic diagram of the assembly of the atomizer 10 and the power supply component 210 in the aerosol generating device 100 provided in the embodiments of this application.

[0067] Please see Figure 1 and Figure 2 The aerosol generating device 100 includes two parts: an atomizer 10 and an aerosol generating host 20. The atomizer 10 can be connected to the aerosol generating host 20 via a plug-in connection or other detachable connection method. The aerosol generating host 20 includes a connected power supply component 210 and a power source 220. After the atomizer 10 is connected to the aerosol generating host 20, the power supply component 210 connects the power source 220 and the atomizer 10 to supply power to the atomizer 10.

[0068] Specifically, the atomizer 10 can be a cylindrical structure, with one axial end connected to the aerosol generating host 20 and the other end forming a mouthpiece assembly 7. The atomizer 10 can be used to contain and limit the aerosol matrix to be heated, and provide a certain amount of heat to the aerosol matrix to be heated under the condition of being powered on, so that the aerosol matrix is ​​heated and atomized to generate aerosol.

[0069] Please see Figure 2 The atomizer 10 includes an atomizing component 1 and an electrode component 2 electrically connected, and also has a reservoir 501 for containing an aerosol matrix. The atomizing component 1 passes through the reservoir 501 and is in communication with it to ensure that the aerosol matrix located in the reservoir 501 can flow to the atomizing component 1. The atomizing component 1 can be connected to the power supply component 210 in the aerosol generating host 20 through the electrode component 2. Under the action of the power supply component 210, the atomizing component 1 can be electrically heated and atomize the aerosol matrix by heating to generate an aerosol.

[0070] Please see Figure 2 and Figure 3 The atomizer 10 can rotate and cooperate with the power supply component 210 in the aerosol generator 20, so that when the atomizer 10 rotates about its own axis relative to the aerosol generator 20, the electrode component 2 of the atomizer 10 can maintain continuous circuit conduction with the power supply component 210.

[0071] For example, the atomizer 10 can be plugged into the aerosol generator 20, allowing the atomizer 10 to rotate relative to the aerosol generator 20 around its own axis without affecting the normal conduction of the circuit; or, the atomizer 10 can be threaded into the aerosol generator 20, so that after the atomizer 10 is assembled in place, the atomizer 10 can conduct the circuit with the aerosol generator 20.

[0072] In this embodiment, the atomizer 10 is omnidirectionally assembled with the aerosol generator, which can effectively reduce the assembly difficulty of the aerosol generating device 100 and improve the assembly efficiency of the aerosol generating device 100.

[0073] In some embodiments, the power supply assembly 210 includes a bias contact 211 and a centering holding portion 212, wherein the bias contact 211 and the centering holding portion 212 are respectively used to cooperate with different electrodes in the electrode assembly 2. For example, the electrode assembly 2 includes a first electrode 21 and a second electrode 22, the bias contact 211 can cooperate with the first electrode 21, and the centering holding portion 212 can cooperate with the second electrode 22.

[0074] Please see Figure 2 and Figure 3 The atomizer 10 is plugged into the aerosol generator 20. In this state, the atomizer 10 can rotate relative to the aerosol generator 20 with its own axis as the axis. The bias contact portion 211 is configured to maintain a rotational sliding engagement with the first electrode 21, and the central holding portion 212 is configured to maintain a rotational sliding engagement with the second electrode 22.

[0075] In this embodiment, one of the bias contact portion 211 and the centering holding portion 212 is the positive electrode, and the other is the negative electrode.

[0076] Specifically, the centering holding part 212 may include an elastic probe, and the biasing contact part 211 may include either an elastic probe or a ring power supply component. The ring power supply component may be a ring spring sheet made of metal, or a ring structure with power supply function disclosed in related technologies such as a ring electrode made of metal or graphene, or a ring probe made of metal.

[0077] Please see Figure 3 At this time, both the centering holding part 212 and the bias contact part 211 are elastic probes. As the atomizer 10 rotates, the bias contact part 211 can always maintain its engagement with the first electrode 21 in the electrode assembly 2, and the centering holding part 212 can always maintain its engagement with the second electrode 22 in the electrode assembly 2.

[0078] Please see Figure 2 A first airway is formed within the atomizing component 1, and a second airway, connected to the first airway, is formed within the mouthpiece component 7. When the user inhales through the mouthpiece component 7, the aerosol formed in the first airway can flow to the second airway and eventually flow out of the mouthpiece component 7 through the second airway.

[0079] In some embodiments, the atomizer 10 further includes a sealing plug 8, which seals the gap between the liquid reservoir 501, the atomizing assembly 1, and the mouthpiece assembly 7. The atomizing assembly 1 is sealed to the inner wall of the first housing 5 by the sealing plug 8 to enclose and form the liquid reservoir 501. Figure 2 Taking the structure shown as an example, the sealing plug 8 is located inside the second airway and closes the second airway, while the remaining part surrounds the atomizing component 1 and points to one end of the mouthpiece component 7.

[0080] It should be noted that the sealing plug 8 is a removable structure. The sealing plug 8 is configured to seal the second air passage in the factory condition and before use. When the user starts using the aerosol generating device 100, the portion of the sealing plug 8 located between the atomizing assembly 1 and the nozzle assembly 7 can be disconnected by pulling the sealing plug 8, thereby releasing the seal on the second air passage without affecting the sealing performance of the liquid storage chamber 501.

[0081] This application also provides an atomizer 10, please refer to... Figure 4 and Figure 5 . Figure 4 This is a schematic diagram of the structure of the atomizer 10 provided in the embodiments of this application. Figure 5 An exploded view of the atomizer 10 provided in the embodiments of this application.

[0082] In addition to the atomizing component 1, electrode component 2, mouthpiece component 7, and sealing plug 8 described above, the atomizer 10 also includes a first housing 5, a mounting base 3, and a sealing component 6. The first housing 5 forms the circumferential outer shell of the atomizer 10, with one end connected to the mouthpiece component 7 and the other end fitted with the electrode component 2. The mounting base 3 is located within the first housing 5 and connects the atomizing component 1 and the electrode component 2. The sealing component 6 is connected to the mounting base 3 to achieve a sealing fit between the mounting base 3 and the first housing 5, preventing the aerosol matrix in the liquid storage chamber 501 from leaking out through the mounting base 3. The sealing component 6 includes a first sealing sleeve 61 and a second sealing sleeve 62 spaced apart along the axial direction of the atomizer 10.

[0083] Please see Figure 4 and Figure 5 The electrode assembly 2 includes a first electrode 21 and a second electrode 22 coaxially arranged, wherein the first electrode 21 is sleeved outside the second electrode 22. In the atomizer 10 provided in this application embodiment, by improving the structure of the electrode assembly 2, the first electrode 21 and the second electrode 22 can be used to achieve omnidirectional assembly of the power supply device of the atomizer 10 and the aerosol generator 20, thereby reducing the assembly difficulty of the atomizer 10 and the aerosol generator 20 and improving the assembly efficiency.

[0084] Please see Figure 5The atomizing assembly 1 includes a mating atomizing core 11 and a positioning block 12. The pins of the atomizing core 11 can be initially fixed by the positioning block 12 to facilitate the assembly of the atomizing core 11 with the electrode assembly 2. The electrode assembly 2 also includes an insulating seal located between the first electrode 21 and the second electrode 22 to ensure that the coaxially arranged first electrode 21 and second electrode 22 can remain insulated, while achieving a good sealing effect between them to prevent the aerosol matrix from leaking out through the gap between the first electrode 21 and the second electrode 22.

[0085] Figure 6 This is a partial structural diagram of the atomizing component 1 in the atomizer 10 provided in the embodiments of this application.

[0086] Please see Figure 5 and Figure 6 The atomizing core 11 includes a heating element 111, a first pin 112, and a second pin 113. The heating element 111 can be a mesh structure or other similar structures. Both the first pin 112 and the second pin 113 are connected to the heating element 111. The positioning block 12 has a first positioning hole 121 and a second positioning hole 122 spaced apart. The first pin 112 can extend through the first positioning hole 121, and the second pin 113 can extend through the second positioning hole 122, so that the positioning block 12 can provide initial fixation for the first pin 112 and the second pin 113. During the assembly of the atomizing core 11 and the electrode assembly 2, the positioning block 12 can prevent damage to the connection between the first pin 112 and the second pin 113 and the heating element 111 due to external pulling, thus helping to improve the reliability of the atomizing core 11.

[0087] In this embodiment, the first pin 112 of the atomizing core 11 is connected to the first electrode 21 of the electrode assembly 2, and the second pin 113 is connected to the second electrode 22 of the electrode assembly 2. When the atomizer 10 rotates about its own axis relative to the aerosol generating host 20, the fixedly connected atomizing core 11 and electrode assembly 2 rotate synchronously. At this time, the electrode assembly 2 can continuously conduct the circuit with the power supply assembly 210. At this time, the first electrode 21 can maintain rotational sliding contact with the first power supply assembly, and the second electrode 22 can maintain rotational sliding contact with the second power supply assembly.

[0088] Please see Figure 6 Both the first pin 112 and the second pin 113 have a bent portion 110, wherein the bent portion 110 of the first pin 112 is connected to the first electrode 21, and the bent portion 110 of the second pin 113 is connected to the second electrode 22.

[0089] The bending portion 110 includes a connected bending section 1101 and a conductive section 1102. Both the first pin 112 and the second pin 113 include extensions for connecting the bending portion 110 and the heating element 111. The bending section 1101 connects the extension and the conductive section 1102. The conductive section 1102 of the first pin 112 is used to contact the first electrode 21, and the conductive section 1102 of the second pin 113 is used to contact the second electrode 22, thereby achieving circuit connection between the atomizing core 11 and the electrode assembly 2.

[0090] Specifically, the conductive section 1102 can be a straight line or a curved structure, and the bent section is a non-straight line structure connecting the conductive section 1102 and the extension, used to achieve a transition connection between the conductive section 1102 and the extension.

The atomizing component 1 can pass through the first base body 31 and contact the second base body 32 to cooperate with the mounting base 3. The electrode component 2 is assembled on the second base body 32, and the first base body 31 and the second base body 32 are connected to realize the electrical connection between the atomizing component 1 and the electrode component 2.

[0093] The first sealing sleeve 61 of the sealing assembly 6 is fitted onto the first seat 31, and the second sealing sleeve 62 is fitted onto the second seat 32, so as to ensure that when the fixed seat 3 is assembled into the first housing 5, the first seat 31 can be sealed with the inner wall of the first housing 5 through the first sealing sleeve 61, and the second seat 32 can be sealed with the inner wall of the first housing 5 through the second sealing sleeve 62.

[0094] Please see Figure 7 The second seat 32 has an air inlet 321. When the user inhales through the nozzle assembly 7, the gas can flow through the air inlet 321 into the first air passage of the atomizing assembly 1, and carry a certain amount of aerosol out through the second air passage. The seat connector 33 avoids the aforementioned air inlet 321.

[0095] Specifically, the outer peripheral sidewall of the second housing 32 is also provided with a buckle 322 and a positioning boss 323. The inner wall of the first housing 5 is formed with a groove (not shown in the figure) that cooperates with the buckle 322. The fixing seat 3 can be engaged with the first housing 5 through the mutually cooperating buckle 322 and groove. The end face of the first housing 5 is provided with a positioning groove (not marked in the figure) that cooperates with the positioning boss 323. When the first housing 5 and the fixing seat 3 are assembled in place, the positioning boss 323 is precisely positioned and engaged with the positioning groove.

[0096] Please see Figure 8 The second body 32 of the fixing base 3 has a mounting hole 301 and a mounting groove 302. The mounting groove 302 is recessed on the side of the second body 32 facing away from the first body 31, and is used to limit the installation of the electrode assembly 2. The mounting hole 301 communicates with the mounting groove 302, allowing the first pin 112 and the second pin 113 of the atomizing core 11 to pass through and be electrically connected to the electrode assembly 2 located in the mounting groove 302. In the axial direction, the end of the second body 32 of the fixing base 3 facing away from the atomizing assembly 1 has a first end face 303, that is, the end of the second body 32 facing away from the first body 31 has a first end face 303. The first end face 303 is arranged around the mounting groove 302 and is located on the outer side of the mounting groove 302 in the radial direction.

[0097] Specifically, along the axial direction of the atomizer 10, a first limiting member 3021 and a second limiting member 3022 are protruding in the mounting groove 302. Both the first limiting member 3021 and the second limiting member 3022 are annular protrusions and are coaxially arranged.

[0098] Please see Figure 9 The first limiting member 3021 is located outside the second limiting member 3022. The first limiting member 3021 and the second limiting member 3022 cooperate to divide the mounting groove 302 into a first mounting groove 3023, a connecting groove 3025 and a second mounting groove 3024. The connecting groove 3025 is located between the first mounting groove 3023 and the second mounting groove 3024 and is connected to the mounting through hole 301. The first mounting groove 3023 is arranged around the outer periphery of the connecting groove 3025.

[0099] Specifically, the radial outer wall of the first limiting member 3021, the circumferential inner wall of the mounting groove 302, and the axial inner wall of the mounting groove 302 together form the first mounting groove 3023, and the inner wall of the second limiting member 3022 together with the bottom wall 30241 forms the second mounting groove 3024; the space between the first limiting member 3021 and the second limiting member 3022 constitutes a connecting groove 3025 that communicates with the mounting through hole 301. The first pin 112 and the second pin 113 can extend into the first mounting groove 3023 and the second mounting groove 3024 respectively through the connecting groove 3025 to achieve electrical connection with the first electrode 21 installed in the first mounting groove 3023 and the second electrode 22 installed in the second mounting groove 3024.

[0100] Specifically, at least a portion of the bent portion 110 of the first pin 112 connected to the first electrode 21 is located in the first mounting groove 3023, and at least a portion of the bent portion 110 of the second pin 113 connected to the second electrode 22 is located in the second mounting groove 3024.

[0101] In some embodiments, the first limiting member 3021 is recessed with a first clearance groove 30211 on the side facing the first mounting groove 3023, and the second limiting member 3022 is recessed with a second clearance groove 30221 on the side facing the second mounting groove 3024. Please refer to [link to relevant documentation]. Figure 9 .

[0102] In some embodiments, the axial end of the first limiting member 3021 is recessed with a first guide groove 30212, which can connect the first mounting groove 3023 and the connecting groove 3025 radially.

[0103] Specifically, one end of the first guide groove 30212 is connected to the connecting groove 3025, and the other end is radially connected to the first clearance groove 30211 formed in the first mounting groove 3023.

[0104] It should be noted that radial connection means that the two ends of the first guide groove 30212 extend to the opposite side walls of the first limiting member 3021, and the extension direction is not required to be parallel to the radial direction. The specific extension direction can be set as needed. Generally, it is a straight groove extending radially. Of course, it can also be an inclined groove at a certain angle to the radial direction.

[0105] Similarly, the axial end of the second limiting member 3022 is recessed with a second guide groove 30222, which radially connects the second mounting groove 3024 and the connecting groove 3025. (See also...) Figure 9 The two ends of the second guide groove 30222 are respectively connected to the second clearance groove 30221 and the connecting groove 3025.

[0106] To facilitate installation, in some embodiments, the first guide groove 30212 and the second guide groove 30222 can be offset circumferentially along the fixing base 3. This structural arrangement can also effectively prevent the first pin 112 and the second pin 113 from contacting each other and short-circuiting within the connecting groove 3025.

[0107] Please refer to the assembly structure of atomizing component 1 and mounting base 3. Figure 10 and Figure 11 .

[0108] Please see Figure 10 Along the axial direction of the atomizer 10, the orthographic projection of the heating element 111 on the fixed base 3 does not coincide with the orthographic projection of the mounting hole 301 on the fixed base 3.

[0109] This structure helps prevent the liquid aerosol matrix from flowing directly along the surface of the heating element 111 to the mounting perforation 301, and further to the connecting groove 3025 through the mounting perforation 301, thereby improving the sealing performance of the atomizer 10 to some extent.

[0110] Please see Figure 10 A limiting protrusion ring 324 is provided on the outer periphery of the mounting hole 301. The limiting protrusion ring 324 is located on the side of the second base 32 facing away from the electrode assembly 2 and is arranged around the mounting hole 301.

[0111] The inner wall of the limiting protrusion ring 324 is a smooth curved surface, and the inner wall of the limiting protrusion ring 324 smoothly transitions with the inner wall of the mounting hole 301, so as to better guide the first pin 112 and the second pin 113 through the mounting hole 301 and assemble them with the fixing seat 3.

[0112] In this embodiment, along the axial direction of the atomizer 10, the bent section 1101 of the first pin 112 is disposed opposite to the end of the first limiting member 3021, and the bent section 1101 of the second pin 113 is disposed opposite to the end of the second limiting member 3022; the conductive section 1102 of the first pin 112 extends into the first mounting groove 3023 to abut against the first electrode member 21; the conductive section 1102 of the second pin 113 extends into the second mounting groove 3024 to abut against the second electrode member 22.

[0113] Please see Figure 11 The bent section 1101 of the first pin 112 is located in the first guide groove 30212, and the conductive section 1102 extends into the first mounting groove 3023 through the first clearance groove 30211.

[0114] It should be noted that the bent section 1101 of the first pin 112 can be set to correspond to the first guide groove 30212, or it can be set to partially or completely pass through the first guide groove 30212.

[0115] Specifically, the assembly method of the second pin 113 is the same as that of the first pin 112. Its bent section 1101 is located in the second guide groove 30222, and the conductive section 1102 extends into the second mounting groove 3024 through the second clearance groove 30221.

[0116] The first electrode 21 in electrode assembly 2 can be mounted to the fixing base 3 through the first mounting groove 3023, and the second electrode 22 can be mounted to the fixing base 3 through the second mounting groove 3024. With the insertion of the first electrode 21, the conductive section 1102 of the first pin 112 can press against the first electrode 21, achieving abutment between the first pin 112 and the first electrode 21, ensuring a robust and reliable electrical connection between them. Similarly, with the insertion of the second electrode 22, the conductive section 1102 of the second pin 113 can press against the second electrode 22, achieving abutment between the second pin 113 and the second electrode 22.

[0117] In this embodiment, the reliability of the assembly of the atomizing core 11 and the electrode assembly 2 can be improved by having the pins and electrode components abut against each other, thus avoiding defects such as poor contact between the two.

[0118] Figure 12 This is a schematic diagram of the structure of the electrode assembly 2 provided in the embodiments of this application. Figure 13 This is a partial cross-sectional structural diagram of the atomizer 10 provided in an embodiment of this application. Figure 14 for Figure 13 Enlarged view of the structure of region B in the middle.

[0119] Please see Figure 12 The first electrode 21 has an overall ring structure, and the second electrode 22 is a columnar structure that passes through the first electrode 21. In this embodiment, the first electrode 21 can be fixedly connected to the fixing base 3 through the first mounting groove 3023, and the second electrode 22 can be fixedly connected to the fixing base 3 through the second mounting groove 3024.

[0120] Specifically, the outer periphery of the first electrode 21 has a first sidewall 2101, a stepped surface 2103, and a second sidewall 2102 connected radially therein, wherein the radial dimension of the first sidewall 2101 is smaller than the radial dimension of the second sidewall 2102, and the stepped surface 2103 connects the first sidewall 2101 and the second sidewall 2102. When the first electrode 21 is connected to the fixing base 3 via the first mounting groove 3023, the first electrode 21 can be press-fitted with the radial sidewall of the first mounting groove 3023 through the first sidewall 2101.

[0121] To further improve the assembly firmness, in this embodiment, a fixing protrusion is provided on a portion of the surface of the first sidewall 2101. In this case, the first sidewall 2101 can be press-fitted with the first mounting groove 3023 via the aforementioned fixing protrusion.

[0122] Specifically, the fixing protrusion can be an annular protrusion extending circumferentially along the first electrode 21.

[0123] Please see Figure 13 and Figure 14 When the stepped surface 2103 in the first electrode 21 comes into contact with the first end face 303 of the fixed seat 3, it indicates that the first electrode 21 has been assembled with the fixed seat 3.

[0124] In order to improve the sealing performance between the first electrode 21 and the fixed seat 3 and prevent the aerosol matrix from leaking out through the gap between the electrode and the fixed seat 3, a first groove 21011 is provided on the first side wall 2101.

[0125] The atomizer 10 also includes a first sealing ring 4, which is fitted onto the first electrode 21 through a first groove 21011 to seal against the mounting base 3.

[0126] When the first electrode 21 is assembled to the fixing seat 3, the first sealing ring 4 can undergo a certain deformation under the compression of external force. At this time, the two radial sides of the first sealing ring 4 can abut against the inner walls of the first groove 21011 and the first mounting groove 3023 respectively, thus having good sealing performance.

[0127] Please see Figure 12 Along the axial direction of the second electrode 22, the second electrode 22 includes a first main body portion 221 and a second main body portion 222 connected together. A second groove 2221 is recessed on the outer periphery of the second main body portion 222. The insulating sealing ring 23 mentioned above can be fitted onto the second main body portion 222 through the second groove 2221.

[0128] The second electrode 22 can be interference-fitted with the second mounting groove 3024 through the first main body 221. At this time, the second main body 222 is located outside the second mounting groove 3024 and can be insulated and sealed with the first electrode 21 through the insulating sealing ring 23.

[0129] To further improve its assembly firmness, in this embodiment, a positioning member 2211 is provided on the outer periphery of the first main body 221, and the first main body 221 is radially interference-fitted with the second mounting groove 3024 through the positioning member 2211.

[0130] Specifically, the positioning element 2211 can be a ring structure extending circumferentially along the first main body 221.

[0131] After assembly, the positioning component 2211 can generate continuous radial pressure through the elastic deformation of the material, thereby achieving fixation with the fixed base 3.

[0132] Please see Figure 12 The positioning ring has a guide slope 22111 on the side facing the bottom wall 30241, and the guide slope 22111 is inclined toward the second main body 222 in a radial direction outward from the axis of the first main body 221.

[0133] Please see Figure 13 and Figure 14 When the axial end of the first main body 221 in the second electrode 22 abuts against the bottom wall 30241 of the second mounting groove 3024, it indicates that the second electrode 22 has been assembled with the fixing seat 3.

[0134] After the second electrode 22 is assembled, the insulating sealing ring 23 can abut against the first electrode 21 and the second electrode 22 on both sides in the radial direction, so as to achieve a firm assembly of the first electrode 21 and the second electrode 22 and improve the sealing performance between the first electrode 21 and the second electrode 22.

[0135] Specifically, both the first sealing ring 4 and the insulating sealing ring 23 mentioned above are annular structures made of materials such as silicone.

[0136] It should be noted that both the first electrode 21 and the second electrode 22 can be made of materials with good conductivity to reduce the contact resistance between the electrode assembly 2 and the atomizing core 11 and the power supply assembly 210.

[0137] Specifically, both the first electrode 21 and the second electrode 22 can be made of brass and have their surfaces plated with gold.

[0138] When assembling the aforementioned mounting base 3 and electrode assembly 2, the first sealing sleeve 61 and the second sealing sleeve 62 in the sealing assembly 6 need to be installed onto the first base 31 and the second base 32 respectively, and then the mounting base 3 is installed into the first housing 5. The first sealing sleeve 61 can achieve a sealing fit with the atomizing assembly 1 and the inner wall of the first housing 5, thereby ensuring that the aerosol matrix in the liquid storage chamber 501 will not leak out through the gap between the mounting base 3 and the atomizing assembly 1 and the first housing 5. The second sealing sleeve 62 can achieve a secondary seal on the inner wall of the mounting base 3 and the first housing 5 to further improve the sealing effect.

[0139] The first pin 112 and the second pin 113 in the atomizing assembly 1 can be bent to form a bent portion 110, which cooperates with the first limiting member 3021 and the second limiting member 3022 on the mounting base 3. The conductive section 1102 in the first pin 112 can extend into the first mounting groove 3023, and the second conductive section 1102 in the second pin 113 can extend into the second mounting groove 3024. The electrode assembly 2 can then be assembled onto the mounting base 3.

[0140] First, the first electrode 21, which is fitted with the first sealing ring 4, is installed into the first mounting groove 3023. The first electrode 21 can achieve circuit conduction with the first pin 112 by compression interference contact. Then, the second electrode 22, which is fitted with the insulating sealing ring 23, is installed into the second mounting groove 3024. The second electrode 22 can achieve circuit conduction with the second pin 113 by compression interference contact.

[0141] It is understood that the atomizer 10 provided in this application embodiment can reduce the difficulty of conducting with the power supply component 210 of the aerosol generating host 20 through the specially constructed first electrode 21 and second electrode 22, thereby achieving omnidirectional assembly and power supply conduction between the atomizer 10 and the aerosol generating host 20. At this time, the atomizer 10 can rotate to any angle around its own axis without affecting the circuit conduction between the atomizer 10 and the aerosol generating host 20. When assembling the atomizer 10 and the aerosol generating host 20 to prepare the aerosol generating device 100, the assembly difficulty of the aerosol generating device 100 can be effectively reduced, and its assembly efficiency improved. In addition, the atomizer 10 also has the advantages of simple structure and good sealing performance.
