[0004] An aerosol-generating device is a device that atomizes a liquid formulation to form an aerosol. In some exemplary prior art, the aerosol-generating device includes an atomizer assembly and a power supply assembly. An electrode of the power supply assembly abuts the atomizer assembly. When the atomizer and the electrode are facing each other, the atomizer and the power supply assembly are electrically connected. The atomizer assembly includes multiple atomizers, and the atomizer assembly is rotated relative to the power supply assembly to sequentially bring the multiple atomizers into facing each other.

[0064] 1-11 , an embodiment of the present application provides an aerosol generating device, which includes a power supply component 3 , an atomizing component 2 , and a rotating component 4 .

[0065] The atomizer assembly 2 includes multiple independent atomizers 21, each configured to operate independently when powered. Each atomizer 21 may include a storage chamber 211 capable of accommodating a liquid matrix. The amount of liquid matrix stored in each atomizer 21 may not exceed 5 ml, for example, approximately 2 ml. The liquid matrix may include a liquid containing a tobacco substance containing volatile tobacco flavor components, or a liquid containing a non-tobacco substance. The liquid matrix may include water, a medicinal solution, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. Flavoring agents may include, but are not limited to, betel nut extract, menthol, peppermint, spearmint oil, or various fruit-flavored ingredients. Flavoring agents may include ingredients that provide the user with various aromas or flavors. The vitamin mixture may include, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. Based on the different properties of the liquid matrix, the aerosol generating device can be used in different fields, such as medical treatment and electronic aerosol generation.

[0066] The term "plurality" refers to two or more. In the embodiments shown in Figures 4 and 5 , there are five atomizers 21, but this is not limiting. At least two of the multiple atomizers 21 can be used to contain different liquid matrices. These different liquid matrices may include liquid matrices with different flavors or ingredients or proportions. This allows users to experience different sensory experiences by switching between atomizers 21. Of course, in one embodiment, all atomizers 21 can contain the same liquid matrices.

[0067] 3 , a liquid storage sponge 212 may be provided in the storage cavity 211 to retain at least a portion of the liquid matrix in the liquid storage sponge 212. The provision of the liquid storage sponge 212 prevents leakage of the liquid matrix. The liquid storage sponge 212 is optional but not mandatory.

[0068] Referring to Figures 3 and 11, each atomizer 21 may also have an atomizer core 213. The atomizer core 213 is in fluid communication with the storage chamber 211 or connected to the liquid storage cotton 212. The atomizer core 213 is used to atomize the liquid matrix to generate an aerosol. The atomizer core 213 may include a liquid absorbing element 2131 and a heating element 2132. The liquid absorbing element 2131 may be a porous body or fiber. The liquid absorbing element 2131 can absorb the liquid matrix and can guide the liquid matrix into the atomization range of the heating element 2132; the heating element 2132 is used to atomize at least part of the liquid matrix on the liquid absorbing element 2131 to form an aerosol. The heating element 2132 can be combined with the liquid absorbing element 2131 so that the heating element 2132 can form a whole with the liquid absorbing element 2131.

[0069] Each atomizer 21 may further include a first electrode 214 and a second electrode 215 , which are electrically connected to the heating element 2132 . The first electrode 214 and the second electrode 215 are used to be electrically connected to the power supply component 3 to draw power from the power supply component 3 to provide heat for the heating element 2132 .

[0070] In the embodiment shown in FIG11 , the second electrode 215 is disposed around the first electrode 214, with an insulating member 216 disposed between the first electrode 214 and the second electrode 215. Specifically, the second electrode 215 may be configured in a tubular shape, and the insulating member 216 connects the first electrode 214 and the second electrode 215 and retains at least a portion of the first electrode 214 within the tubular second electrode 215.

[0071] In one example, referring to FIG. 11 , each atomizer 21 further includes a first wire 217 electrically connecting the heating element 2132 and the first electrode 214, with an insulating gap between the first wire 217 and the second electrode 215. At least a portion of the first wire 217 can be disposed within the tubular second electrode 215. The end of the first wire 217 can be clamped between the insulating member 216 and the first electrode 214 to maintain electrical connection with the first electrode 214. It should be noted that the first wire 217 can also maintain electrical connection with the first electrode 214 through other means, such as welding.

[0072] In one example, referring to FIG. 3 , each atomizer 21 may further include a second wire 218 electrically connecting the heating element 2132 and the second electrode 215, with an insulating gap between the second wire 218 and the first electrode 214. At least a portion of the second wire 218 may be disposed within the tubular second electrode 215. The end of the second wire 218 may be clamped between the insulating member 216 and the second electrode 215 to maintain electrical connection with the second electrode 215. It should be noted that the second wire 218 may also maintain electrical connection with the second electrode 215 through other means, such as welding.

[0073] 11 , the first electrode 214 and the second electrode 215 are distributed in the transverse direction, and the second electrode 215 encompasses the first electrode 214. In other examples, the first electrode 214 and the second electrode 215 are distributed in the transverse direction and do not encompass each other.

[0074] Each atomizer 21 may further include an air inlet fluidically connected to the atomizer core 213. Air enters the interior of the atomizer 21 through the air inlet and then flows toward the atomizer core 213. The air inlet may penetrate the side wall of the atomizer 21. The air inlet may penetrate the bottom wall of the atomizer 21 and be disposed toward the power supply assembly 3. The air inlet may penetrate the first electrode 214 or the second electrode 215. The air inlet may penetrate the insulating member 216 between the first electrode 214 and the second electrode 215.

[0075] At least a portion of the side wall of the atomizer 21 may be transparent, so that a user can observe the remaining amount of the liquid matrix in the storage chamber 211 through the side wall of the atomizer 21 .

[0076] Each atomizer 21 may also have an air supply channel and an air outlet 219. The air supply channel fluid connects the atomizing core 213 and the air outlet 219. The aerosol generated by atomization of the atomizing core 213 is guided to the air outlet 219 via the air supply channel. The storage chamber 211 can be arranged around the air supply channel, or the air supply channel can be arranged on one side of the storage chamber 211.

[0077] In one example, the atomizer 21 may have an atomizing compartment in fluid communication with the storage chamber 211 , the atomizing core 213 is accommodated in the atomizing compartment, the air supply channel is in fluid communication with the atomizing compartment, and the storage chamber 211 is located between the air outlet 219 and the atomizing compartment.

[0078] Alternatively, in another example, referring to Figure 11, at least a portion of the atomizer core 213 is arranged in the air supply channel, and a liquid guide hole is provided on the air supply channel. The atomizer core 213 is fluidically connected to the storage chamber 211 or connected to the liquid storage cotton 212 through the liquid guide hole. The liquid matrix in the storage chamber 211 or the liquid storage cotton 212 can pass through the liquid guide hole and be absorbed by the liquid absorption element 2131 and atomized by the heating element 2132, or a portion of the liquid absorption element 2131 can pass through the liquid guide hole into the storage chamber 211 to absorb and conduct the liquid matrix.

[0079] In one embodiment, referring to Figures 4 and 5 , the multiple atomizers 21 are distributed in the horizontal direction. For example, the multiple atomizers 21 can be arranged in a straight line in the horizontal direction. For example, referring to Figures 4 and 5 , the multiple atomizers 21 can be arranged in an array in the horizontal direction, or in the same circular shape in the horizontal direction.

[0080] In one embodiment, referring to Figures 4, 5, 7, and 9, the atomizer assembly 2 further includes a holder 22, which is used to hold a plurality of atomizers 21. Specifically, the holder 22 may include a plurality of partition plates 221 and a plurality of holding spaces 222. The plurality of atomizers 21 may be held in the plurality of holding spaces 222 in a one-to-one correspondence. The plurality of holding spaces 222 may be separated by a plurality of partition plates 221 in pairs, and the plurality of atomizers 21 may be separated by a plurality of partition plates 221 in pairs.

[0081] The holder 22 may include a housing 223 that surrounds the plurality of atomizers 21. The partition plate 221 may form an integral structure with the housing 223, for example, by integral injection molding. At least a portion of the housing 223 may be transparent, allowing a user to observe the remaining amount of liquid substrate within the storage chamber 211 through the sidewalls of the housing 223 and the atomizer 21.

[0082] The rotating assembly 4 can rotate relative to the power supply assembly 3 or the atomizer assembly 2, and during the rotation of the rotating assembly 3, at least a portion of the power supply assembly 2 or at least one atomizer 21 moves in the longitudinal direction. The longitudinal direction is perpendicular to the transverse direction, and the rotating assembly 4 and the atomizer assembly 2 are in different positions in the longitudinal direction. When at least a portion of the power supply assembly 3 and the atomizer 21 moves in the longitudinal direction or when the two move in opposite directions in the longitudinal direction, the distance between the two can be increased or decreased. In one embodiment, the rotation axis of the rotating assembly 4 is parallel to the longitudinal direction, and therefore, the rotation plane of the rotating assembly 4 and the moving direction of the atomizer 21 can be perpendicular to each other.

[0083] When the rotating assembly 4 rotates by the first preset angle, at least one atomizer 21 and the power supply assembly 3 approach each other in the longitudinal direction until they abut against each other, thereby being electrically connected to each other, and at least one of the remaining atomizers 21 moves away from the power supply assembly 3 in the longitudinal direction, thereby being spaced apart from each other, so that when the rotating assembly 4 rotates by the first preset angle, at least one atomizer 21 can replace another or other atomizers 21 to abut against the power supply assembly 3.

[0084] In one embodiment, when the rotating assembly 4 rotates by a first predetermined angle, only one of the plurality of atomizers 21 abuts against the power supply assembly 3 , and the remaining atomizers 21 are spaced apart from the power supply assembly 3 .

[0085] In one embodiment, referring to Figures 4 and 5 , multiple atomizers 21 are arranged horizontally in a circle, and the rotating assembly 4 is capable of rotating along a single direction through multiple first preset angles. Each time the rotating assembly 4 rotates through a first preset angle, at least one atomizer 21 can replace another or more atomizers 21 in electrical connection with the power supply assembly 3. The magnitude of the first preset angle can be related to the number of atomizers 21. For example, when there are two atomizers 21, the first preset angle can be 180°. For example, when there are four atomizers 21, the first preset angle can be 90°. For example, when there are five atomizers 21, the first preset angle can be 72°.

[0086] The rotating assembly 4 can be rotated in only one direction. The rotating assembly 4 can be rotated in one direction and in the opposite direction. The rotating assembly 4 can be rotated 360 degrees.

[0087] By rotating the rotating assembly 4, at least a portion of the power supply assembly 3 or at least one atomizer 21 is moved longitudinally, rather than rotating the atomizing assembly 2 relative to the power supply assembly 3, thereby preventing the power supply assembly 3 from being worn.

[0088] In a first aspect of the present application, when the rotating assembly 4 rotates, it can cause one or more atomizers 21 to move longitudinally. During the rotation of the rotating assembly 4, the rotating assembly 4 can drive at least one atomizer 21 to move longitudinally from a first position to a second position, and the atomizer 21 can be maintained in the second position by the rotating assembly 4 so that it abuts the power supply assembly 3. The rotating assembly 4 can also drive different atomizers 21 from the first position to the second position through the rotation process, thereby selecting different atomizers 21 to be electrically connected to the power supply assembly 3.

[0089] Based on this, in one embodiment, the atomizer 21 is configured to be movable longitudinally between a first position and a second position, and the rotating assembly 4 includes a pushing member 41, which is used to push the corresponding atomizer 21 from the first position to the second position, and the pushing member 41 is made to correspond to different atomizers 21 by rotating the rotating assembly 4; wherein the atomizer 21 pushed to the second position is electrically connected to the power supply assembly 3.

[0090] When the atomizer 21 is electrically connected to the power supply assembly 3 , the atomizer 21 can generate aerosol, or when the user turns on the power switch or under further operation of the user, the atomizer 21 can generate aerosol.

[0091] The atomizer 21, which is currently offset from the pushing member 41, can remain in the first position or return to the first position from the second position because it is not affected by the rotating assembly 3. The atomizer 21 in the first position is spaced apart from the power supply assembly 3, and the electrical connection between the atomizer 21 and the power supply assembly 3 is disconnected.

[0092] In the embodiment shown in Figures 2 and 3 , the upper end of one of the atomizers 21 is abutted by the pushing member 41, causing the atomizer 21 to be in the second position, and the first electrode 214 and the second electrode 215 provided at the lower end of the atomizer 21 respectively abut the first continuous electrode 31 and the second continuous electrode 32 of the power supply assembly 3. The other atomizer 21 shown in Figures 2 and 3 does not correspond to the pushing member 41 and is in the first position, spaced apart from the power supply assembly 3.

[0093] When the atomizer 21 moves between the first position and the second position, the atomizer 21 can be slidably connected to the retaining member 22 or the corresponding partition plate 221. The retaining member 22 can have a limiting or guiding function to prevent the atomizer 21 from shifting in the lateral direction during the longitudinal movement. The retaining member 22 can have an anti-rotation structure to prevent one or more atomizers 21 from rotating during the rotation of the rotating assembly 4. To prevent rotation, the retaining space 222 can be designed into a non-circular shape and / or the sidewall of the atomizer 21 can be designed into a non-circular profile.

[0094] In one embodiment, referring to Figures 3 and 8 , the rotating assembly 4 is configured to be movable longitudinally between a third position and a fourth position during rotation. In Figure 3 , the rotating assembly 4 is in the fourth position, while in Figure 4 , the rotating assembly 4 is in the third position. Figure 8 shows the atomizer 21, both those associated with the push member 41 and those not associated with the push member 41, in the first position.

[0095] When the rotating assembly 4 moves from the third position to the fourth position, the pushing member 41 pushes the at least one atomizer 21 from the first position to the second position.

[0096] The direction of movement of the rotating assembly 4 from the third position to the fourth position can be the same as the direction of movement of the atomizer 21 from the first position to the second position. When the rotating assembly 4 is in the fourth position, the pushing member 41 can directly contact and abut the corresponding atomizer 21, thereby maintaining the atomizer 21 in the second position and maintaining a stable electrical connection between the atomizer 21 and the power supply assembly 3.

[0097] In one embodiment, referring to Figures 2 and 10 , the aerosol generating device further comprises a first return mechanism 6 , which is elastically connected to the rotating assembly 4 to provide a force to maintain the rotating assembly 4 in the fourth position, thereby preventing the rotating assembly 4 from unexpectedly moving out of the fourth position. When the rotating assembly 4 is in the third position, the first return mechanism 6 can be elastically connected to the rotating assembly 4 to apply at least one force toward the fourth position, thereby urging the rotating assembly 4 to move from the third position toward the fourth position.

[0098] The first reset mechanism 6 can include at least one of a spring, rubber, silicone, or sponge. When the rotating assembly 4 is in the fourth position, the elastic component in the first reset mechanism 6 can be in an elastically deformed state, such as an elastically compressed state or an elastically stretched state. When the rotating assembly 4 is in the third position, the elastic component in the first reset mechanism 6 is subjected to an increased degree of elastic deformation, such as an increased degree of elastic compression or an increased degree of elastic stretching. Of course, in this example, when the rotating assembly 4 is in the fourth position, the elastic component in the first reset mechanism 6 can be in a natural state, while when the rotating assembly 4 is in the third position, the elastic component in the first reset mechanism 6 is subjected to an elastically deformed state, such as an elastically compressed state or an elastically stretched state.

[0099] The first reset mechanism 6 can be arranged inside the rotating assembly 4 so as not to occupy the space of the holder 22 , so that the holder 22 can accommodate more atomizers 21 or the atomizer 21 held by the holder 22 can have a larger volume or capacity.

[0100] In one example, referring to FIG. 2 and FIG. 10 , the atomizing assembly 2 includes a connecting portion 23 connected to the retaining member 22 , and the rotating assembly 4 includes a main body 42 having a through hole.

[0101] The lateral dimension of the connecting portion 23 is smaller than the lateral dimension of the through hole, so that the connecting portion 23 can rotatably pass through the through hole. For example, the outer diameter of the connecting portion 23 can be smaller than or equal to the inner diameter of the through hole, so that when the rotating assembly 4 rotates relative to the atomizing assembly 2, the connecting portion 23 can rotate in the through hole. Preferably, the through hole is located at the center of the main body 42, and the central axis of the through hole is collinear with the rotation axis of the rotating assembly 4.

[0102] The connecting portion 23 is movable longitudinally relative to the through hole, allowing the rotating assembly 4 to move between the third and fourth positions. The connecting portion 23 includes an end cap 233 , and at least a portion of the first return mechanism 6 is disposed between the end cap 233 and the main body 42 , so as to apply at least one force to the rotating assembly 4 in the direction of the fourth position when the rotating assembly 4 is in the third position.

[0103] Specifically, referring to Figures 2 and 10, the connecting portion 23 includes a first connecting portion 231 and a second connecting portion 232 that are connected to each other. The first connecting portion 231 is connected to the retaining member 22, and the second connecting portion 232 has an end cap 233. The main body 42 is disposed between the end cap 233 and the retaining member 22, and at least one of the first connecting portion 231 and the second connecting portion 232 passes through a through hole in the main body 42. The lateral dimension of the end cap 233 can be larger than the lateral dimension of the through hole to prevent the second connecting portion 232 from exiting the rotating assembly 4 and preventing the rotating assembly 4 from separating from the atomizing assembly 2.

[0104] In the embodiment shown in Figures 2 and 10, the elastic component in the first reset mechanism 6 is a spring, which is arranged inside the rotating assembly 4, and the main body 42 is located between the spring and the retaining member 22. The spring surrounds the periphery of the connecting portion 23, and when the rotating assembly 4 is in the third position, the spring is in an elastically compressed state.

[0105] In one embodiment, as shown in Figures 6 and 7, the rotating assembly 4 includes a first protrusion 43 and a first recessed portion 44 that is recessed relative to the first protrusion 43, and the retaining member 22 includes a second protrusion 224. When the rotating assembly 4 is in the fourth position, at least a portion of the second protrusion 224 is embedded in the first recessed portion 44, so that the rotating assembly 4 and the atomizing assembly 2 are interlocked to prevent relative rotation between the two. When the rotating assembly 4 is in the third position, as shown in Figure 8, the second protrusion 224 is disengaged from the first recessed portion 44, so that the interlock between the rotating assembly 4 and the atomizing assembly 2 is released, so that the rotating assembly 4 can rotate relative to the atomizing assembly 2 under the action of an external force.

[0106] The interlocking between the rotating assembly 4 and the atomizing assembly 2 prevents the rotating assembly 4 from rotating unexpectedly, thereby ensuring that the pushing member 41 can relatively stably abut the current atomizer 21, so that the current atomizer 21 can maintain a relatively stable electrical connection with the power supply assembly 3.

[0107] In the embodiment shown in Figure 7, the retaining member 22 also has a second recessed portion 225 that is recessed relative to the second protrusion 224, and at least a portion of the second protrusion 224 is embedded in the first recessed portion 44, and at least a portion of the first protrusion 43 is embedded in the second recessed portion 225.

[0108] In one embodiment, when the rotating assembly 4 rotates through a second predetermined angle, the pushing member 41 is rotated to be positioned between two adjacent atomizers 21, and the first protrusion 43 abuts the second protrusion 224. Furthermore, when the rotating assembly 4 rotates through a second predetermined angle to a third position, the first protrusion 43 abuts the second protrusion 224, thereby maintaining the rotating assembly 4 in the third position. At this point, the pushing member 41 is no longer aligned with any atomizer 21, allowing all atomizers 21 to be simultaneously in the first position.

[0109] The fourth position of the rotating assembly 4 and the second position of at least one atomizer 21 are defined as the initial position of the rotating assembly 4. Rotating the rotating assembly 4 by a first preset angle enables another atomizer 21 or a plurality of atomizers 21 to replace the previous atomizer 21 and be electrically connected to the power supply assembly 3. Rotating the rotating assembly 4 by a second preset angle enables all atomizers 21 to be spaced apart from the power supply assembly 3, thereby disconnecting all atomizers 21 from the power supply assembly 3. The second preset angle may be smaller than the first preset angle. The direction of rotating the rotating assembly 4 by the first preset angle may be the same as the direction of rotating the rotating assembly 4 by the second preset angle, for example, both rotation directions may be clockwise.

[0110] In one embodiment, referring to Figure 3, the pushing member 41 has an air flow channel 411 inside, and the atomizer 21 located in the second position is connected to the air flow channel 411 inside the pushing member 41. The outside air can enter the corresponding atomizer 21 through the air flow channel 411, or the air flow in the atomizer 21 can enter the user's mouth through the air flow channel 411.

[0111] The atomizer 21 in the second position and the pushing member 41 can elastically abut against each other, so that the connection between the atomizer 21 and the air flow channel 411 is a sealed connection, preventing other atomizers 21 that do not correspond to the pushing member 41 from communicating with the air flow channel 411, which is beneficial for improving the puffing taste.

[0112] As an example, the push member 41 is made of a flexible material, such as silicone or rubber. Referring to FIG3 , the push member 41 can be generally tubular, with a mounting hole 45 formed on the main body 42 of the rotating assembly 4, into which the push member 41 is embedded and fixed. A portion of the push member 41 extends longitudinally and is positioned between the main body 42 and the retaining member 22 , such that the end (first end) of this portion of the push member 41 can elastically abut the atomizer 21 . Another portion of the push member 41 extends longitudinally and protrudes relative to the main body 42 , forming a stepped structure between the end (second end) of the other portion of the push member 41 and the bottom of the main body 42 . The airflow channel 411 longitudinally extends through the push member 41 , connecting the first end and the second end.

[0113] In the embodiment shown in FIG3 , when the pushing member 41 corresponds to an atomizer 21 , the air flow channel 411 in the pushing member 41 is directly opposite to the air outlet 219 of the atomizer 21 and is fluidically connected thereto. The air flow channel 411 in the pushing member 41 can even be coaxial with the air outlet 219 of the atomizer 21 .

[0114] When the pushing member 41 is rotated to be located between two adjacent atomizers 21, the air flow channel 411 in the pushing member 41 and the air outlets 219 of the two atomizers 21 are staggered. In the longitudinal projection, there is no overlap between the projection of the air flow channel 411 in the pushing member 41 and the projection of the air outlets 219 of the two atomizers 21.

[0115] In one embodiment, as shown in Figures 2 and 3 , the aerosol generating device further includes a mouthpiece 1, at least a portion of which can be held in the mouth of a user, who inhales the aerosol by suctioning the mouthpiece 1. A rotating assembly 4 is disposed between the atomizing assembly 2 and the mouthpiece 1, and an airflow channel 411 in the pushing member 41 communicates with the mouthpiece 1.

[0116] In one example, referring to Figure 3 , the second end of the push member 41 is free and spaced apart from the mouthpiece 1. Aerosol from the atomizer 21 can be directed into the rotating assembly 4 via the airflow channel 411 in the push member 41, and then into the mouthpiece 1. The main body 42 of the rotating assembly 4 defines a cavity 46, which connects the mouthpiece 1 and the airflow channel 411 in the push member 41. This cavity 46 can also store condensate formed by condensation of the aerosol. The stepped structure between the second end and the bottom of the main body 42 prevents condensate stored at the bottom of the cavity 46 from entering the airflow channel 411 through the opening at the second end.

[0117] It should be noted that, in other examples, the atomizing assembly 2 may be disposed between the mouthpiece 1 and the rotating assembly 4 , so that the aerosol generated by the atomizer 21 can enter the mouthpiece 1 without passing through the rotating assembly 4 .

[0118] In one embodiment, when the rotating assembly 4 changes position by rotating, or when the rotating assembly 4 is moved to the third position, the atomizer 21 previously corresponding to the pushing member 41 and located at the second position can automatically return from the second position to the first position.

[0119] For example, referring to FIG. 2 and FIG. 9 , the aerosol generating device further includes a second reset mechanism 7 , which elastically abuts against the atomizer 21 in the second position to provide a force to move the atomizer 21 from the second position to the first position.

[0120] As an example, referring to Figures 2 and 9, the second reset mechanism 7 includes a fixing portion 71 connected to the retaining member 22 and a plurality of springs 72 connected to the fixing portion 71. Each atomizer 21 has at least one spring 72 correspondingly arranged therewith. When the atomizer 21 is pushed from the second position, the at least one spring 72 elastically abuts the atomizer 21 and provides at least one force to the atomizer 21 in the direction of the first position. When the force applied by the pushing member 41 on the atomizer 21 decreases or disappears, the spring 72 of the second reset mechanism 7 can rebound the atomizer 21 in the second position to the first position, so that the atomizer 21 is spaced apart from the power supply assembly 3, thereby disconnecting the electrical connection between the atomizer 21 and the power supply assembly 3.

[0121] As an example, the second reset mechanism 7 elastically abuts the atomizer 21 located in the first position to maintain the atomizer 21 in the first position, preventing the atomizer 21 from automatically moving from the first position to the second position without being abutted by the pushing member 41, so that only the atomizer 21 abutted by the pushing mechanism 41 can be located in the second position.

[0122] As an example, the spring piece 72 of the second reset mechanism 7 and the pushing member 41 are located on opposite sides of the atomizer assembly 2 .

[0123] In one embodiment, referring to Figures 2-5 , the power supply assembly 3 includes a first continuous electrode 31, which is electrically connected to the positive terminal of the power supply. The first continuous electrode 31 extends horizontally and is continuous. Different atomizers 21 pushed to the second position can respectively abut different positions of the first continuous electrode 31, thereby electrically connecting to the first continuous electrode 31. When multiple atomizers 21 are arranged in a straight line in the horizontal direction, the first continuous electrode 31 can be a strip electrode, which can be straight or wavy. When multiple atomizers 21 are arranged in the same circle in the horizontal direction, the first continuous electrode 31 can be a ring electrode, which can be a closed ring, such as an "O" shape, or an open ring, such as a "C" shape.

[0124] In one embodiment, referring to FIG. 5 , the first continuous electrode 31 includes a first base 311 and a plurality of first conductive sheets 312 disposed on the first base 311 and corresponding one-to-one with the atomizers 21. An atomizer 21 pushed to the second position elastically abuts against its corresponding first conductive sheet 312. The plurality of first conductive sheets 312 are electrically connected to one another via the first base 311, so that any atomizer 21 abutting against any first conductive sheet 312 can be electrically connected to the first base 311. The first conductive sheets 312 can be elastic.

[0125] In one embodiment, referring to Figures 2-5 , the power supply assembly 3 includes a second continuous electrode 32 , which is electrically connected to the negative terminal of the power supply. The second continuous electrode 32 extends horizontally and is continuous. Different atomizers 21 pushed to the second position can respectively abut different positions of the second continuous electrode 32 , thereby electrically connecting to the second continuous electrode 32 . When multiple atomizers 21 are arranged in a straight line in the horizontal direction, the second continuous electrode 32 can be a strip-shaped electrode. When multiple atomizers 21 are arranged in a circular shape in the horizontal direction, the second continuous electrode 32 can be a ring-shaped electrode.

[0126] In one embodiment, referring to FIG. 5 , the second continuous electrode 32 includes a second base 321 and a plurality of second conductive sheets 322 disposed on the second base 321 and corresponding one-to-one with the atomizers 21. An atomizer 21 pushed to the second position elastically abuts against its corresponding second conductive sheet 322. The plurality of second conductive sheets 322 are electrically connected to one another via the second base 321, so that any atomizer 21 abutting against any second conductive sheet 322 can be electrically connected to the second base 321. The second conductive sheets 322 can be elastic.

[0127] In one embodiment, referring to FIG. 5 , the first continuous electrode 31 and the second continuous electrode 32 are both ring electrodes.

[0128] In one embodiment, the aerosol generating device includes a power supply assembly 5, which is electrically connected to a power supply assembly 3 to provide power to the atomizer assembly 2 via the power supply assembly 3. The power supply assembly 5 includes a power supply and a circuit board. The power supply can be any suitable battery, such as a lithium battery. The circuit board can include one or more controllers for controlling the output of the power supply, such as controlling the power supply to the atomizer assembly 2 or controlling other operations of the aerosol generating device. The power supply assembly 3 can be fixed to the circuit board.

[0129] In a second aspect of the present application, when the rotating assembly 4 rotates, it can cause a portion of the power supply assembly 3 to move longitudinally. Thus, by rotating the rotating assembly 4, a portion of the power supply assembly 3 is moved longitudinally until it abuts at least one atomizer 21, while another portion or portions of the power supply assembly 3 are moved longitudinally until they are disconnected from the atomizer 21 they were originally abutting.

[0130] In one embodiment (not shown), the power supply assembly includes a plurality of power supply members corresponding to the plurality of atomizers, each of which is configured to be movable longitudinally. The rotation assembly includes a push member configured to push the corresponding power supply member to electrically connect to the corresponding atomizer. The rotation assembly rotates to align the push members with different power supply members.

[0131] In the first aspect of the present application, when the rotating assembly 4 rotates, the pushing member 41 can push the corresponding atomizer 21 to move longitudinally until it is electrically connected to the power supply assembly 3. When the atomizer 21 moves longitudinally, the power supply assembly 3 can remain in its original position. In the second aspect of the present application, when the rotating assembly 4 rotates, the pushing member 41 can push the corresponding power supply member to move longitudinally until it is electrically connected to the corresponding atomizer 21. When the power supply member moves longitudinally, the atomizer 21 can remain in its original position. In one embodiment, when the rotating assembly rotates, the corresponding atomizer 21 and the power supply member can both move longitudinally, and preferably, the directions of their longitudinal movement are opposite.

[0132] Based on the first aspect or the second aspect, in one embodiment, the atomizing assembly 2 is disposed between the suction nozzle 1 and the rotating assembly 4 , or the rotating assembly 4 is disposed between the atomizing assembly 2 and the suction nozzle 1 .

[0133] The suction nozzle 1 can be directly or indirectly connected to the rotating assembly 4. As an example, the suction nozzle 1 can rotate together with the rotating assembly 4. As an example, the rotating assembly 4 can rotate relative to the suction nozzle 1, that is, when the rotating assembly 4 rotates, the suction nozzle 1 may not rotate.

[0134] 5 , the rotating assembly 4 includes a rotating drive portion 47 , at least part of which is exposed on the surface of the aerosol generating device. The user can manually drive the rotating drive portion 47 to rotate the rotating assembly 4 .

Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
