Further, the power supply module 2 includes the power supply 22, and the power supply 22 may include any suitable battery, for example, may include a lithium battery, a rechargeable battery, or a single-use battery.

In some embodiments, a quantity of pairs of power supply electrodes 21 is less than a quantity of atomization cores 11, so that only one or only some of the atomization cores 11 can be electrically connected to the power supply electrodes 21, and establish a power supply path with the power supply 22 based on the power supply electrodes 21.

Further, the power supply electrode 21 is configured to be capable of rotating relative to the atomization module 1, to select an atomization core 11 to be electrically connected to the power supply electrode 21.

The power supply module 2 is configured to be capable of rotating relative to the atomization module 1. The second connection component 23 and the first connection component 312 may be connected to keep the suction nozzle module 3 on a side of the atomization module 1.

Further, an interference structure is disposed on the first connection component 312 and/or the second connection component 23, a connection between the first connection component 312 and the second connection component 23 has an unlocked state and a locked state, and the first connection component 312 and the second connection component 23 can keep connected in both the unlocked state and the locked state.

Furthermore, the first connection component 312 and the second connection component 23 are capable of keeping relative rotation in the unlocked state, and rotation between the first connection component 312 and the second connection component 23 can be restricted in the locked state by the interference structure, for the power supply electrode 21 and the suction port 311 or the air guiding channel 321 to synchronously rotate relative to the atomization module 1.

Therefore, the suction nozzle module 3 may be randomly connected to the power supply module 2 or the atomization module 1. Then, the first connection component 312 and the second connection component 23 are rotated relative to each other, for the first connection component 312 and the second connection component 23 to automatically change from the unlocked state to the locked state, so that the power supply electrode 21 of the power supply module 2 can rotate synchronously with the suction port 311 or the air guiding channel 321 of the suction nozzle module 3 relative to the atomization module 1, helping improve assembly efficiency.

In some embodiments, a first magnetic component 33 is disposed on the first connection component 312, a second magnetic component 24 is disposed on the second connection component 23, and the first connection component 312 and the second connection component 23 keep connected through magnetic attraction between the first magnetic component 33 and the second magnetic component 24. In addition, when the first connection component 312 and the second connection component 23 are in the unlocked state, the first connection component 312 and the second connection component 23 can be kept in a rotatable connection through magnetic attraction between the first magnetic component 33 and the second magnetic component 24.

Further, the power supply module 2 rotates relative to the atomization module 1 around a central axis of the first magnetic component 33 or the second magnetic component 24, to prevent deviation of a central axis of the suction nozzle module 3 during rotation of the power supply module 2 relative to the atomization module 1.

In some embodiments, when the first connection component 312 and the second connection component 23 are in the locked state, the power supply electrode 21 is electrically connected to one of the atomization cores 11, and the atomization core 11 is also in communication with the air guiding channel 321 and/or the suction port 311.

In some embodiments, at least a part of the second connection component 23 passes through the atomization module 1, and the atomization module 1 is capable of rotating around a central axis of the second connection component 23. In this case, the power supply electrode 21 and the suction nozzle module 3 may be disposed on two opposite sides of the atomization module 1.

In some embodiments, the interference structure includes a first insertion groove 3121 and a first insertion portion 231. One of the first connection component 312 and the second connection component 23 is provided with the first insertion groove 3121, and the other includes the first insertion portion 231. When the first connection component 312 and the second connection component 23 are in the unlocked state, the first insertion portion 231 is not inserted into the first insertion groove 3121. When the first connection component 312 and the second connection component 23 are in the locked state, the first insertion portion 231 is inserted into the first insertion groove 3121.

Specifically, when the first connection component 312 and the second connection component 23 are in the unlocked state, the first insertion groove 3121 and the first insertion portion 231 are not aligned, so that the first insertion portion 231 is not inserted into the first insertion groove 3121. When the first connection component 312 and the second connection component 23 are in the locked state, the first insertion groove 3121 and the first insertion portion 231 are aligned, so that the first insertion portion 231 can be inserted into the first insertion groove 3121.

In some embodiments, the first insertion portion 231 is of a non-centrosymmetric structure or is in a non-centrosymmetric shape, so that the first insertion portion 231 after rotating around a point by 180° cannot coincide with the first insertion portion 231 before the rotation. The first insertion groove 3121 is of a non-centrosymmetric structure or is in a non-centrosymmetric shape, so that the first insertion groove 3121 after rotating around a point by 180° cannot coincide with the first insertion groove 3121 before the rotation. Therefore, the first insertion groove 3121 and the first insertion portion 231 have a unique alignment angle.

When the first insertion portion 231 is inserted into the first insertion groove 3121, the atomization core electrically connected to the power supply electrode 21 is also in communication with the suction port.

In some embodiments, the first connection component 312 is configured to be capable of rotating relative to the second connection component 23 when the first insertion portion 231 is not inserted into the first insertion groove 3121, so that the first insertion portion 231 and the first insertion groove 3121 can be aligned through relative rotation of the first connection component 312 and the second connection component 23.

Further, when the first insertion portion 231 is inserted into the first insertion groove 3121, the first connection component 312 and the second connection component 23 form an interference fit in a transverse direction, so that the first connection component 312 and the second connection component 23 can rotate synchronously, and then the power supply electrode 21 and the suction port 311 or the air guiding channel can synchronously rotate relative to the atomization module 1. Therefore, after the first insertion portion 231 is inserted into the first insertion groove 3121, if the atomization module 1 is driven to rotate relative to the power supply electrode 21, the atomization core 11 electrically connected to the power supply electrode 21 and the atomization core 11 in communication with the suction port 311 can be changed at the same time, and the atomization core 11 electrically connected to the power supply electrode 21 is the same as the atomization core 11 in communication with the suction port 311.

Therefore, the suction nozzle module 3 may be randomly connected to the power supply module 2 or the atomization module 1. If the first insertion portion 231 is not aligned with the first insertion groove 3121, the first connection component 312 and the second connection component 23 may be rotated relative to each other to align the first insertion portion 231 with the first insertion groove 3121. After the first insertion portion 231 and the first insertion groove 3121 are aligned, the first insertion portion 231 is inserted into the first insertion groove 3121, to enable the first connection component 312 and the second connection component 23 to form an interference fit and keep synchronous rotation. Then, the power supply module 2 may be operated or the suction nozzle module 3 may be operated or another operation component may be operated to enable the power supply electrode 21 and the suction port 311 or the air guiding channel 321 to synchronously rotate relative to the atomization module 1.

In some embodiments, after the first insertion portion 231 and the first insertion groove 3121 are aligned, the first insertion portion 231 is configured to be capable of being automatically inserted into the first insertion groove 3121.

For example, the suction nozzle module 3 includes the first magnetic component 33, the power supply module 2 or the atomization module 1 is provided with the second magnetic component 24, and the second magnetic component 24 is configured to magnetically attract the first magnetic component 33 to enable the first insertion portion 231 to be automatically inserted into the first insertion groove 3121 when the first insertion portion 231 and the first insertion groove 3121 are rotated to be aligned.

Therefore, because both the first insertion portion 231 and the first insertion groove 3121 are of a non-centrosymmetric structure or in a non-centrosymmetric shape, the first insertion groove 3121 and the first insertion portion 231 have a unique alignment angle or interference fit angle. After the first insertion portion 231 and the first insertion groove 3121 are aligned through relative rotation, the first insertion portion 231 can be automatically inserted into the first insertion groove 3121 through magnetic attraction between the first magnetic component 33 and the second magnetic component 24. In this case, the atomization core 11 electrically connected to the power supply electrode 21 is also in communication with the suction port 311.

Both the first magnetic component 33 and the second magnetic component 24 may include a magnet. One of the first magnetic component 33 and the second magnetic component 24 may include a magnet, and the other may include a magnetic product that can be magnetically attracted by the magnet, for example, may include an iron plate or an iron block.

In some embodiments, as shown in FIG. 5, the first magnetic component 33 is kept on the first connection component 312. In some embodiments, as shown in FIG. 3, the second magnetic component 24 is kept on the second connection component 23.

Further, the connection component including the first insertion portion 231 has a first retention groove 232 for retaining the magnetic component, and the connection component including the first insertion groove 3121 has a second retention groove 3122 for retaining the magnetic component. Further, the first insertion groove 3121 is configured to be in communication with the second retention groove 3122 and provide a channel for the corresponding magnetic component to enter the second retention groove 3122, so that the corresponding magnetic component can pass through the first insertion groove 3121 and then enter the second retention groove 3122 to be retained.

For example, as shown in FIG. 6, the first connection component 312 is provided with the first insertion groove 3121, and then the first connection component 312 is further provided with the second retention groove 3122. The first magnetic component 33 may be retained in the second retention groove 3122 and then retained on the first connection component 312. An area of the first insertion groove 3121 is greater than or equal to an area of the second retention groove 3122, so that the first magnetic component 22 can pass through the first insertion groove 3121 and be assembled into the second retention groove 3122, and then be retained in the second retention groove 3122.

For example, as shown in FIG. 4, the second connection component 23 includes the first insertion portion 231, and then the second connection component 231 is provided with the first retention groove 232. The second magnetic component 24 may be retained in the first retention groove 232 and then retained on the second connection component 23. Further, the first retention groove 232 is provided on the first insertion portion 231, so that when the first insertion portion 231 is inserted into the first insertion groove 3121, at least a part of the second magnetic component 24 is also located in the first insertion groove 3121. Furthermore, an end that is of the first retention groove 232 and that faces the suction nozzle module 2 is open, for assembly of the second magnetic component 24.

In the embodiment shown in FIG. 2, when the first insertion portion 231 is inserted into the first insertion groove 3121, the first magnetic component 33 and the second magnetic component 24 are disposed face-to-face, and may be in direct contact.

In some embodiments, as shown in FIG. 4 and FIG. 5, one of the first connection component 312 and the second connection component 23 is provided with a protruding tooth 3123, the other is provided with a tooth groove 233, and when the first insertion portion 231 is inserted into the first insertion groove 3121, the protruding tooth 3123 is located in the tooth groove 233, for the first connection component 312 and the second connection component 23 to be engaged, so that the first connection component 312 and the second connection component 23 can rotate synchronously.

For example, the first connection component 312 includes the protruding tooth 3123. The protruding tooth 3123 may be disposed in the first insertion groove 3121 and spaced apart from a groove wall of the first insertion groove 3121. Alternatively, as shown in FIG. 5, the protruding tooth 3123 may be located in the first insertion groove 3121 and connected to a groove wall of the first insertion groove 3121.

The second connection component 23 includes the tooth groove 233. As shown in FIG. 4, the tooth groove 233 may be recessed inward from an outer side wall of the first insertion portion 231, or may be recessed, in a direction away from the suction nozzle module 3, from an end surface that is of the second connection component 231 and that faces the suction nozzle module 3.

The protruding tooth 3123 and the corresponding tooth groove 233 may have matching sizes, to reduce lateral play of the protruding tooth 3123 inserted into the tooth groove 233.

There may be same quantities of protruding teeth 3123 and tooth grooves 233.

There may be only one protruding tooth 3123 and one corresponding tooth groove 233, or there may be only one tooth groove 233 and one corresponding protruding tooth 3123, so that the first insertion groove 3121 and the first insertion portion 231 are of a non-centrosymmetric structure or in a non-centrosymmetric shape.

There may be a plurality of protruding teeth 3123 and a plurality of corresponding tooth grooves 233. In an example, at least two protruding teeth 3123 have different shapes or sizes, so that the first insertion groove 3121 is of a non-centrosymmetric structure or in a non-centrosymmetric shape. Correspondingly, at least two tooth grooves 233 have different shapes or sizes, so that the first insertion portion 231 is of a non-centrosymmetric structure or in a non-centrosymmetric shape. In an example, the plurality of protruding teeth 3123 are distributed in the first insertion groove 3121 in a non-centrosymmetric manner. Correspondingly, the plurality of tooth grooves 233 are distributed on the first insertion portion 231 in a non-centrosymmetric manner.

In some embodiments, as shown in FIG. 5, a part of a groove wall of the first insertion groove 3121 is a planar groove wall 3124, a part of an outer side wall of the first insertion portion 231 is a planar side wall 234, and when the first insertion portion 231 is inserted into the first insertion groove 3121, the planar side wall 234 faces the planar groove wall 3124. In this case, the first insertion groove 3121 is a non-circular groove, and the first insertion portion 231 has a non-circular cross-section, so that when the first insertion portion 231 is inserted into the first insertion groove 3121, the first connection component 312 and the second connection component 23 can form an interference fit in a transverse direction, and then the first connection component 312 and the second connection component 23 can rotate synchronously.

There may be only one planar groove wall 3124 and one planar side wall 234, so that the first insertion groove 3121 and the first insertion portion 231 are of a non-centrosymmetric structure or in a non-centrosymmetric shape.

There may be a plurality of planar groove walls 3124 and/or a plurality of planar side walls 234. However, a distribution or shape of one or more planar groove walls 3124 allows the first insertion groove 3121 to be of a non-centrosymmetric structure or in a non-centrosymmetric shape, and a distribution or shape of one or more planar side walls 234 allows the first insertion portion 231 to be of a non-centrosymmetric structure or in a non-centrosymmetric shape.

In some embodiments, not shown in the figure, the suction nozzle module includes a first part and a second part. The first part includes the suction port, and the first part is configured to keep a static correspondence with the atomization module. The second part includes the air guiding channel and the first connection component, so that the air guiding channel can keep a static correspondence with the first connection component. A quantity of air guiding channels is less than a quantity of air guiding tubes (for example, there may be only one air guiding channel). Moreover, the second part and the first part are rotatably connected, so that the power supply electrode and the second part can synchronously rotate relative to the atomization module and the suction port, to select the air guiding tube to be in communication with the air guiding channel. The air guiding tube in communication with the air guiding channel may be in communication with the suction port through the air guiding channel, and the atomization core corresponding to the air guiding tube in communication with the air guiding channel is electrically connected to the power supply electrode. When the power supply electrode is driven to rotate relative to the atomization module, the power supply electrode may further rotate relative to the first part at the same time, and the second part including the first connection component can synchronously rotate with the power supply electrode, so that the second part can rotate relative to the first part and the atomization module at the same time. Therefore, in a process of selecting the air guiding tube to be in communication with the air guiding channel, the atomization module and the first part including the suction port can keep static together.

In some embodiments, as shown in FIG. 6 and FIG. 7, the suction nozzle module 3 includes a first part 31 and a second part 32, the first part 31 includes the first connection component 312 and the suction port 311, the second part 32 is provided with a plurality of air guiding channels 321 that are in communication with the plurality of air guiding tubes 13 in a one-to-one correspondence, and the first part 31 is configured to be rotatably connected to the second part 32, to select, through rotation, the air guiding channel 321 to be in communication with the suction port 311. The atomization core 11 corresponding to the air guiding channel 321 in communication with the suction port 311 is also electrically connected to the power supply electrode 21, so that the atomization core 11 can obtain electric power to generate an aerosol, and the generated aerosol can be guided to the suction port 311 through the corresponding air guiding tube 13 and air guiding channel 321.

Further, the second part 32 and the atomization module 1 form an interference fit in a transverse direction, so that the second part 32 can keep a static correspondence with the atomization module 1. In this case, when the first insertion portion 231 is inserted into the first insertion groove 3121, the power supply electrode 21 and the first part 31 including the first connection component 312 may synchronously rotate relative to the atomization module 1 and the second part 32.

When the power supply electrode 21 is driven to rotate relative to the atomization module 1, the power supply electrode 21 may further rotate relative to the second part 32 at the same time, and the first part 31 including the first connection component 312 can synchronously rotate with the power supply electrode 21, so that the first part 31 can rotate relative to the second part 32 and the atomization module 1 at the same time. Therefore, in a process of selecting the air guiding channel 321 to be in communication with the suction port 311, the atomization module 1 and the second part 32 including the air guiding channel 321 can keep static together.

Furthermore, as shown in FIG. 4 and FIG. 5, one of the atomization module 1 and the second part 32 is provided with a second insertion groove 17, and the other includes a second insertion portion 34. When the first insertion portion 231 is inserted into the first insertion groove 3121, at least a part of the second insertion portion 34 is inserted into the second insertion groove 17, so that the atomization module 1 and the second part 32 form an interference fit in a transverse direction.

When the first insertion portion 231 is not inserted into the first insertion groove 3121, at least a part of the second insertion portion 34 may also be inserted into the second insertion groove 17. This helps keep the suction nozzle module 3 and the atomization module 1 connected in a process in which the first connection component 312 and the second connection component 23 rotate relative to each other.

In the embodiment shown in FIG. 2, the second part 32 is located between the first part 31 and the atomization module 1, the second part 32 is provided with a through hole, at least a part of the first connection component 312 is disposed in the through hole, and the second part 32 is configured to be rotatable around the first connection component 312.

In the embodiment shown in FIG. 7, the first connection component 312 is provided with an anti-detachment portion 3125, at least a part of the second part 32 is rotatably disposed between the suction port 311 and the anti-detachment portion 3125, and the anti-detachment portion 3125 is configured to prevent detachment of the second part 32 from the first part 31. Further, the first part 31 further includes a base 313 and a suction nozzle 314 connected to the base 313, the suction port 311 is provided on the suction nozzle 314, the first connection component 312 is connected to the base 313 and is located on a side that is of the base 313 and that faces away from the suction nozzle 314, and at least a part of the second part 32 is rotatably disposed between the base 313 and the anti-detachment portion 3125.

In some embodiments, the suction nozzle module 3 is removably connected to the power supply module 2, accommodation space 251 is constructed between the suction nozzle module 3 and the power supply module 2 when the suction nozzle module 3 and the power supply module 2 are connected, the accommodation space 251 is provided to removably accommodate the atomization module 1, and the atomization module 1 is configured to be irremovably kept in the accommodation space 251 when the suction nozzle module 3 and the power supply module 2 are connected. Therefore, only after the suction nozzle module 3 is removed from the power supply module 2, the atomization module 1 can be removed from the power supply module 2, or a new atomization module 1 can be connected to the power supply module 2.

The suction nozzle module 3 and the power supply module 2 can implement a removable connection between the suction nozzle module 3 and the power supply module 2 through magnetic attraction between the first magnetic component 33 and the second magnetic component 24.

It may be understood that the suction nozzle module 3 may also be connected to the atomization module 1 in a removable manner, so that the suction nozzle module 3, the atomization module 1, and the power supply module 2 can be separated from each other and can be assembled with each other.

In some embodiments, as shown in FIG. 3, the power supply module 2 further includes a first outer shell 25 with accommodation space 251 inside, the first outer shell 25 is provided with an assembly hole, and the atomization module 1 is configured to be capable of being assembled into the accommodation space 251 and being removed from the accommodation space 251 through the assembly hole; and the suction nozzle module 3 and the power supply module 2 are removably connected, and the assembly hole is obstructed when the suction nozzle module 3 is connected to the power supply module 2. Therefore, when the suction nozzle module 3 and the power supply module 2 are connected, removal of the atomization module 1 from the accommodation space 251 can be prevented and assembly of the atomization module 1 into the accommodation space 251 can be prevented.

In some embodiments, when the atomization module 1 is located in the accommodation space 251, the atomization module 1 may rotate relative to the first outer shell 25, so that the atomization module 1 can be rotatably accommodated in the first outer shell 25.

In some embodiments, when the atomization module 1 is located in the accommodation space 251, the atomization module 1 and the first outer shell 25 form an interference fit in a transverse direction, for the atomization module 1 and the first outer shell 25 to synchronously rotate relative to the second connection component 23 and the power supply electrode 21.

In some embodiments, the suction nozzle module 3 is configured to keep connected with the power supply module 2 or the atomization module 1 through magnetic attraction between the first magnetic component 33 and the second magnetic component 24 in a process in which the first connection component 312 rotates relative to the second connection component 23. In addition, when the first insertion portion 231 is not inserted into the first insertion groove 3121, there is a first distance between the suction port 311 and the atomization module 1. When the first insertion portion 231 is inserted into the first insertion groove 3121, there is a second distance between the suction port 311 and the atomization module 1. The first distance is greater than the second distance.

Therefore, in a case that the first insertion portion 231 is not inserted into the first insertion groove 3121, the first connection component 312 is rotated relative to the second connection component 23, so that the first connection component 312 and the second connection component 23 are aligned. Then, the first insertion portion 231 is automatically inserted into the first insertion groove 3121. A sound and vibration generated during insertion serve as an insertion indication signal, and a change from the first distance to the second distance can also generate a visual signal to indicate whether the first insertion portion 231 has been inserted into the first insertion groove 3121.

In some embodiments, as shown in FIG. 5, the suction nozzle module 3 has a shoulder 35. When the first insertion portion 231 is not inserted into the first insertion groove 3121, an end portion that is of the first outer shell 25 and that is adjacent to the suction nozzle module 3 has a large gap with the shoulder 35 in a longitudinal direction, and the shoulder 35 is located outside the first outer shell 25. When the first insertion portion 231 is inserted into the first insertion groove 3121, the end portion that is of the first outer shell 25 and that is adjacent to the suction nozzle module 3 contacts the shoulder 35 in the longitudinal direction, or has a small gap with the shoulder 35 in the longitudinal direction, so that a part of the suction nozzle module 3 is kept outside the first outer shell 25, for a user to hold. The user can observe a longitudinal distance between the shoulder 25 and the end portion that is of the first outer shell 25 and that is adjacent to the suction nozzle module 3, to determine whether the first insertion portion 231 is inserted into the first insertion groove 3121.

In some embodiments, when the first insertion portion 231 is not inserted into the first insertion groove 3121, a part of the second part 32 of the suction nozzle module 3 is exposed outside the first outer shell 25. When the first insertion portion 231 is inserted into the first insertion groove 3121, the suction nozzle module 3 descends, and the second part 32 of the suction nozzle module 3 is completely concealed in the first outer shell 25.

In some embodiments, as shown in FIG. 2 and FIG. 8, the power supply module 2 further includes a first support 26 and a connection column 27 extending in a longitudinal direction in the accommodation space 251. The power supply electrode 21 is held on the first support 26, so that the power supply electrode 21 can keep a static correspondence with the first support 26. The connection column 27 connects the first support 26 and the second connection component 23. The first support 26 and the second connection component 23 may be located at two opposite ends of the connection column 27.

When the atomization module 1 is located in the accommodation space 251, at least a part of the connection column 27 is rotatably disposed inside the atomization module 1, so that the atomization module 1 can rotate around the connection column 27, or the connection column 27 can rotate inside the atomization module 1.

Preferably, the first support 26 and the connection column 27 are integrally formed by injection molding.

In some embodiments, as shown in FIG. 2 and FIG. 8, the power supply module 2 further includes a second support 28 rotatably connected to the first support 26 and a hollow tube 29 that is connected to the second support 28 and that extends in the longitudinal direction in the accommodation space 251, so that the hollow tube 29 can keep a static correspondence with the second support 28. Preferably, the hollow tube 29 and the second support 28 are integrally formed by injection molding.

The connection column 27 is rotatably connected to the second connection component 23 through the hollow tube 29. When the atomization module 1 is located in the accommodation space 251, the atomization module 1 and the second support 28 form an interference fit in the transverse direction, for the atomization module 1, the second support 28, and the hollow tube 29 to synchronously rotate relative to the connection column 27 and the power supply electrode 21.

The hollow tube 29 is disposed between the first support 26 and the second connection component 23, and the hollow tube 29 is configured to be capable of blocking the second connection component 23 and the first support 26, to prevent the connection column 27 from exiting the hollow tube 29. In this case, the first support 26 and the second support 28 can keep connected, so that detachment of the second support 28 from the first support 26 can be prevented or detachment of the hollow tube 29 from the connection column 27 can be prevented when the atomization module 1 is removed from the accommodation space 251.

Further, an outer radius of the second connection component is greater than an inner radius of the hollow tube. The radius is defined as a maximum distance between a center and an edge. The connection column may be connected to the second connection component through assembly. Specifically, after the hollow tube is sleeved on the connection column, the connection column is connected to the second connection component.

In some embodiments, at least a part of the second support 28 is disposed in the first outer shell 25, and the second support 28 and the first outer shell 25 form an interference fit in a transverse direction, so that the second support 28, the hollow tube 29, and the first outer shell 25 can synchronously rotate relative to the connection column 27. The second support 28 and the first outer shell 25 may be integrally formed through insert molding. The second support 28 may be at least partially fitted into the first outer shell 25 by riveting and be integrated with the first outer shell 25.

One of the first support 26 and the second support 28 may be provided with a protrusion, and the other may be provided with a groove. In a process of relative rotation of the first support 26 and the second support 28, when the protrusion is rotated to the corresponding groove, vibration and/or a sound is generated, to indicate that the power supply electrode 21 has been electrically connected to one or more atomization cores 11. In addition, an interference fit between the protrusion and the groove in a transverse direction can provide resistance to rotation of the first support 26 relative to the second support 28, to prevent an electrical disconnection between the power supply electrode 21 and the corresponding atomization core 11 in an unexpected case.

In some embodiments, as shown in FIG. 3 and FIG. 4, the power supply module 2 further includes a second outer shell 30, at least a part of the first support 26 is held in the second outer shell 30, and the power supply 22 may also be held in the second outer shell 30. The first outer shell 25 may rotate relative to the second outer shell 30.

It should be noted that the specification and the accompanying drawings of this application provide preferred embodiments of this application, but are not limited to the embodiments described in this specification. Further, a person of ordinary skill in the art may make improvements or variations according to the foregoing descriptions, and all these improvements and variations shall fall within the protection scope of the claims of this application.
