[0041] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0045] Please see Figure 1 and Figure 2 The atomizing device provided in the embodiments of this application will now be described. The atomizing device includes a power supply assembly 100, a mouthpiece assembly 200, and a cartridge replacement assembly 300. The mouthpiece assembly 200 is connected to the power supply assembly 100. The power supply assembly 100 can accommodate multiple atomizers 2. The cartridge replacement assembly 300 is installed on the power supply assembly 100 and can drive the atomizers 2 to slide along the axial direction of the atomizing device to switch between a non-use position M1 and a use position M2.

[0046] in, Figure 2 The direction indicated by the middle arrow is the axial direction of the atomizer, and M1 and M2 are the schematic positions of the two workstations of atomizer 2.

[0047] Additionally, it should be noted that for the atomizer 2 to activate, three conditions must be met simultaneously: air intake connection, air exhaust connection, and electrical connection. The non-use position M1 refers to a position where the atomizer 2 does not simultaneously possess these three conditions. The use position refers to a position where the atomizer 2 simultaneously possesses both air intake and air exhaust connections, and the atomizer 2 is electrically connected to the power supply component 100. The power supply component 100 supplies power to the atomizer 2, enabling it to heat and atomize the internal atomizing medium to form an aerosol. The generated aerosol can then flow out through the mouthpiece assembly 200.

[0048] The atomizing device in this embodiment has a power supply assembly 100 capable of accommodating multiple atomizers 2. The flavors of each atomizer 2 can be the same or different, allowing the atomizing device to carry multiple atomizers 2 to meet the user's vaping needs and increasing the user's choice of flavor. Simultaneously, the cartridge replacement assembly 300 can drive the atomizer 2 to slide along the axial direction of the atomizing device to switch between a non-use position and a use position. The movement of the atomizer 2 is simple, and cartridge replacement is convenient. Furthermore, since the atomizer 2 slides along the axial direction of the atomizing device to achieve cartridge replacement, the problem of the atomizer 2 scratching the electrodes due to movement perpendicular to the axial direction of the atomizing device can be avoided.

[0049] In one embodiment, see Figures 2 to 4 The cartridge replacement assembly 300 includes multiple cartridge replacement units 3000, each cartridge replacement unit 3000 being installed on the power supply assembly 100. Each cartridge replacement unit 3000 can slide along the axial direction of the atomizing device on the power supply assembly 100 and has a first position P1 and a second position P2. The cartridge replacement unit 3000 sliding between the first position P1 and the second position P2 can drive the atomizer 2 to switch between the non-use position M1 and the use position M2.

[0050] Specifically, the number of cartridge changing units 3000 is the same as the number of atomizers 2, and each cartridge changing unit 3000 is configured in a one-to-one correspondence with an atomizer 2. The cartridge changing unit 3000 has a first position P1 and a second position P2. When the cartridge changing unit 3000 is in the first position P1, the atomizer 2 is in the non-use position M1; when the cartridge changing unit 3000 slides to the second position P2, the cartridge changing unit 3000 moves the atomizer 2 to the use position M2.

[0051] In this embodiment, multiple cartridge changing units 3000 distinguish each atomizer 2, thereby making the movement of each atomizer 2 relatively independent, so that only a portion of the atomizer 2 is in use position M2 at any given time. In addition, the sliding of the cartridge changing unit 3000 drives the sliding of the atomizer 2, which improves the sliding stability of the atomizer 2.

[0052] In one embodiment, the cartridge replacement unit 3000 forms an axially synchronous sliding connection with the atomizer 2 along the axial direction of the atomizing device. This axially synchronous sliding connection means that the cartridge replacement unit 3000 and the atomizer 2 are designed with a connecting structure or a limiting structure, allowing the cartridge replacement unit 3000 to slide synchronously with the atomizer 2 along the axial direction of the atomizing device, thus enabling the cartridge replacement unit 3000 to slide along the axial direction of the atomizing device with the atomizer 2. Specifically, the cartridge replacement unit 3000 may form an axially synchronous sliding connection with the atomizer 2 through axial abutment and limiting; alternatively, the cartridge replacement unit 3000 may also form a snap-fit ​​connection with the atomizer 2 to achieve a synchronous sliding connection. Furthermore, the cartridge replacement unit 3000 may cover at least a portion of the outer periphery of the atomizer 2 to axially limit the atomizer 2, thereby ensuring the sliding stability of the atomizer 2. Alternatively, the power supply assembly 100 may also limit the circumferential direction of the atomizer 2 to ensure its sliding stability.

[0053] In one embodiment, see Figure 3 and Figure 4 When the reloading unit 3000 located in the first position P1 slides from the first position P1 to the second position P2, it can trigger the reloading unit 3000 located in the second position P2 to return to the first position P1.

[0054] Specifically, such as Figure 3 and Figure 4 Initially, the right-side refill unit 3000 is in position P1, and the left-side refill unit 3000 is in position P2. Correspondingly, the right-side atomizer 2 is in non-use position M1, and the left-side atomizer 2 is in use position M2. When the right-side refill unit 3000 slides from position P1 to position P2, it triggers the left-side refill unit 3000 to return to position P1, thereby causing the left-side atomizer 2 to return to non-use position M2.

[0055] This design allows users to switch atomizer 2 from its unused position M1 to its used position M2 simply by sliding the left-side refill unit 3000 from its first position P1 to its second position P2. The atomizer 2 on the right side will then automatically return to its unused position M1 via the right-side refill unit 3000. This eliminates the need for the user to first switch the right-side atomizer 2 to its unused position M1 using the right-side refill unit 3000 and then switch the left-side atomizer 2 to its used position M2 using the left-side refill unit 3000. This reduces the difficulty of use, simplifies operation, and improves the user experience.

[0056] In one embodiment, see Figures 2 to 4The power supply assembly 100 includes a limiting member 350 and an axial reset member 360. The limiting member 350 restricts the reloading unit 3000 located at the second position P2 from sliding towards the first position P1. When the reloading unit 3000 located at the first position P1 slides from the first position P1 to the second position P2, it can drive the limiting member 350 to move, so that the limiting member 350 releases the limiting member from the reloading unit 3000 located at the second position P2. The axial reset member 360 is used to push the reloading unit 3000 back to the first position P1 when the limiting member is released.

[0057] Similarly, for ease of description, let's use... Figures 2 to 4 Taking two refill units 3000 as an example, in the initial state, the refill unit 3000 on the right is in position 1 P1, and the refill unit 3000 on the left is in position 2 P2. Correspondingly, the atomizer 2 on the right is in the non-use position M1, and the atomizer 2 on the left is in the use position M2. The principle is the same when there are more than two refill units 3000.

[0058] Among them, the right-side cartridge replacement unit 3000 can drive the limiting member 350 to move. Specifically, when the right-side cartridge replacement unit 3000 slides from the first position P1 to the second position P2 along the axis of the atomizing device, it can drive the limiting member 350 to rotate or move so that the limiting member 350 releases the restriction on the left-side cartridge replacement unit 3000.

[0059] In this embodiment, the limiting member 350 restricts the left-side cartridge replacement unit 3000 from sliding towards the first position P1, thus keeping the left-side cartridge replacement unit 3000 in the second position P2. This keeps the left-side atomizer 2 in the usage position M2, ensuring the stability of the atomizer 2 in the usage position. Simultaneously, the sliding of the right-side cartridge replacement unit 3000 drives the limiting member 350 to move, releasing it from its restriction on the left-side cartridge replacement unit 3000. This ingenious structural design and movement relationship between the cartridge replacement unit 3000 and the limiting member 350 enables the triggering of the limiting member 350. Furthermore, the axial reset member 360 allows the left-side cartridge replacement unit 3000 to automatically reset to the first position P1 after being released from its restriction, eliminating the need for manual reset and simplifying user operation, thus improving the user experience. Understandably, in other embodiments of this application, a structural design can be used between the left and right reloading units 3000 to allow the right reloading unit 3000 to directly limit the left reloading unit 3000 and to contact the limiting effect on the left reloading unit 3000 during sliding. Alternatively, other structures of the power supply assembly 100 can also limit the reloading unit 3000; this is not the only possible approach.

[0060] The left-side cartridge replacement unit 3000 abuts against the limiting member 350 and the axial reset member 360 along the axial direction of the atomizing device. The axial limiting member 350 can abut the left-side cartridge replacement unit 3000 against the limiting member 350 to ensure the stability of the cartridge replacement unit 3000 in the second position P2.

[0061] In one embodiment, see Figures 2 to 4 The limiting member 350 is rotatably disposed between each of the changing assemblies 300. When the changing unit 3000 located at the first position P1 slides from the first position P1 to the second position P2, it can drive the limiting member 350 to rotate so that the limiting member 350 releases the limiting member 350 from the changing unit 3000 located at the second position P2. The limiting member 350 is connected to a rotation reset member 370 for rotating and resetting the limiting member 350.

[0062] By rotatably positioning the limiting member 350 between each reloading unit 3000, a limiting connection can be formed between the same limiting member 350 and multiple reloading units 3000, reducing the number of limiting members 350 and the space occupied. Only one reloading unit 3000 is in the second position P2 at any given time. When one of the reloading units 3000 moves from the first position P1 to the second position P2, it drives the limiting member 350 to rotate forward by a preset angle. When the reloading unit 3000 moves to the second position P2, the limiting member 350 will rotate backward by a preset angle under the action of the rotation reset member 370 to reset, thereby enabling the limiting member 350 to re-limit the reloading unit 3000 in the second position P2.

[0063] In one embodiment, see Figure 3 , Figures 5 to 7 Each limiting member 350 has a limiting part 351 corresponding to the position of each cartridge changing assembly 300. The limiting part 351 includes a first limiting surface 3511, a second limiting surface 3512, and a connecting surface 3513. The first limiting surface 3511 and the second limiting surface 3512 are arranged opposite to each other along the axial direction of the atomizing device, and the connecting surface 3513 connects the first limiting surface 3511 and the second limiting surface 3512. Figure 7As shown, the reloading unit 3000 is provided with a mating part 312. The mating part 312 located at the first position P1 is limited to the first limiting surface 3511, and the mating part 312 located at the second position P2 is limited to the second limiting surface 3512. When the reloading unit 3000 slides from the first position P1 to the second position P2, the mating part 312 abuts against the first limiting surface 3511 to push the limiting member 350 to rotate forward by a preset angle until the mating part 312 abuts against the connecting surface 3513, so that the reloading unit 3000 located at the second position P1... The mating part 312 of 2 disengages circumferentially from the second limiting surface 3512, and the changing unit 3000 located in the second position P2 is axially reset under the action of the axial reset member 360; when the mating part 312 continues to slide axially to disengage from the connecting surface 3513, the rotating reset member 370 drives the limiting member 350 to reverse the preset angle and reset, so that the mating part 312 located in the first position P1 is engaged with the first limiting surface 3511, and the mating part 312 located in the second position P2 is engaged with the second limiting surface 3512.

[0064] For details, please refer to Figure 7The first limiting surface 3511 is an inclined surface that forms an angle with the axis of the atomizing device. The mating part 312 has a first mating surface 3121 that fits and abuts against the first limiting surface 3511. When the refilling unit 3000 is in the first position P1, the mating part 312 is located on the side of the first limiting surface 3511 away from the second limiting surface 3512. The first mating surface 3121 of the mating part 312 abuts against the first limiting surface 3511, thereby restricting the refilling unit 3000 from moving towards the second position P2 through the first limiting surface 3511. When the user drives the reloading unit 3000 to move from the first position P1 to the second position P2, the first mating surface 3121 abuts against the first limiting surface 3511. Since both the first mating surface 3121 and the first limiting surface 3511 are inclined surfaces, they can push the limiting member 350 to rotate in the forward direction. When the limiting member 350 rotates in the forward direction by a preset angle, the sliding mating part 312 corresponds exactly to the position of the connecting surface 3513, and the mating part 312 located at the second position P2 also corresponds exactly to the position of the connecting surface 3513. The axial limiting of the mating part 312 by the limiting part 351 is canceled, and the reloading unit 3000 can be reset to the first position P1 under the action of the axial reset member 360. Furthermore, when the user continues to push the cartridge replacement unit 3000 along the axial direction of the atomizer, the sliding mating part 312 disengages from the connecting surface 3513 along the axial direction, and the circumferential restriction of the sliding mating part 312 on the connecting surface 3513 is canceled. The limiting member 350 can rotate in the opposite direction by a preset angle under the action of the rotating reset member, thereby resetting the limiting member 350. Then, the sliding mating part 312 is limited to the second limiting surface 3512, which means that the cartridge replacement unit 3000 after sliding down is kept in the second position P2, and the sliding mating part 312 after sliding up is limited to the first limiting surface 3511, which means that the cartridge replacement unit 3000 after sliding up is kept in the first position P1.

[0065] For details, please refer to Figure 4 and Figure 7 The second limiting surface 3512 is a plane perpendicular to the axis of the atomizing device. The axial reset member 360 abuts against the side of the cartridge replacement assembly 300 away from the second limiting surface 3512. The second limiting surface 3512 and the axial reset member 360 abut against the opposite sides of the cartridge replacement assembly 300 located at the second position P2, so as to jointly keep the cartridge replacement assembly 300 located at the second position P2 in the second position P2.

[0066] In one embodiment, the connecting surface 3513 is located on the opposite side of the first limiting surface 3511 and the second limiting surface 3512 along the circumferential direction of the limiting member 350, so that when the limiting member 350 is pushed to rotate a preset angle in the positive direction, the sliding mating part 312 and the sliding mating part 312 are exactly at the position of the connecting surface 3513 along the circumferential direction.

[0067] In one embodiment, see Figure 6 Each limiting member 350 has a groove 352 corresponding to each limiting part 351. The first limiting surface 3511, the connecting surface 3513 and the second limiting surface 3512 are part of the inner wall of the groove 352. The mating part 312 located at the first position P1 and the mating part 312 located at the second position P2 are respectively housed in different grooves 352. The grooves 352 guide, house and limit the mating part 312 to prevent the mating part 312 from detaching from the limiting member 350.

[0068] In one embodiment, see Figure 6 The groove 352 passes through the end of the limiting member 350 away from the nozzle assembly 200, so that the mating part 312 can be slid into the groove 352 during assembly.

[0069] In one embodiment, see Figure 2 , Figure 3 and Figure 8 The power supply assembly 100 includes a main housing 110 and a first bracket 120. Each atomizer 2 is housed in the main housing 110, and a cartridge replacement unit 3000 is slidably mounted on the main housing 110. A rotating shaft 1111 extends downward from the top center of the main housing 110. A limiting member 350 is rotatably sleeved on the rotating shaft 1111. A rotation reset member 370 is a torsion spring and is sleeved on the rotating shaft 1111. The first bracket 120 is installed in the main housing 110 and is detachably connected to the main housing 110. The limiting member 350 abuts axially between the rotation reset member 370 and the first bracket 120, and the rotation reset member 370 is connected to the limiting member 350 to provide a pre-tension force for the limiting member 350 to rotate in the opposite direction. In this embodiment, the rotatable installation of the limiting member 350 within the main housing 110 is achieved through the mutually detachable connection between the main housing 110 and the first bracket 120. This simplifies the structure of the limiting member 350, making it easy to assemble and disassemble, and also simplifies the structure of the main housing 110. It is understood that in other embodiments of this application, the axial limiting of the limiting member 350 can also be achieved by providing a convex ring and an annular groove between the limiting member 350 and the rotating shaft 1111. In this case, the axial limiting of the limiting member 350 through the first bracket 120 is not necessary, and this is not the only possible embodiment.

[0070] In one embodiment, the first bracket 120 is fixed to the main housing 110 by a snap-fit ​​mechanism. For details, please refer to [link to relevant documentation]. Figure 8 and Figure 9A first locking block 124 is formed on the outer peripheral wall of the first bracket 120, and a first locking groove 1112 is formed on the inner peripheral wall of the main housing 110. The first locking block 124 is engaged in the first locking groove 1112 to form a locking connection between the first bracket 120 and the main housing 110. It can be understood that in other embodiments of this application, the first bracket 120 can also be installed in other ways, such as by screw locking, or other structures can be used to form axial and circumferential limiting of the first bracket 120 in the main housing 110, thereby fixing the first bracket 120 in the main housing 110.

[0071] In one embodiment, see Figure 3 and Figure 7 The reloading unit 3000 extends with an elastic arm 313, and the power supply assembly 100 has a slot 125. The elastic arms 313 of each reloading unit 3000 are inserted into the slot 125. When the reloading unit 3000 slides from the first position P1 to the second position P2, the elastic arm 313 can be inserted from the slot opening 1251 of the slot 125 into the bottom 1252 of the slot 125, and the cross-sectional area of ​​the bottom 1252 is less than the sum of the cross-sectional areas of the two elastic arms 313.

[0072] The cross-sectional area of ​​the bottom of the tank 1252 refers to the cross-sectional area of ​​the bottom of the tank 1252 along the axis perpendicular to the atomizing device, which is also the inner diameter of the bottom of the tank 1252.

[0073] The elastic arm 313 is elastic and includes a fixed end 3132 and a movable end 3131. The fixed end 3132 is integrally connected to the cartridge changing assembly 300, and the movable end 3131 is the end of the elastic arm 313 facing away from the cartridge changing assembly 300. The movable end 3131 is inserted into the slot 125. The cross-sectional area of ​​the elastic arm 313 refers to the cross-sectional area of ​​the movable end 3131 of the elastic arm 313 along the axis perpendicular to the atomizing device.

[0074] If the cross-sectional area of ​​the slot bottom 1252 is less than the sum of the cross-sectional areas of the two elastic arms 313, then only one elastic arm 313 of the cartridge replacement unit 3000 can be inserted into the slot bottom 1252 of the slot 125 at a time, which means that only one cartridge replacement component 300 is in the second position P2 at a time, and only one atomizer 2 is in the working position at a time.

[0075] like Figure 3In practical applications, in the initial state after assembly, the left-side reloading unit 3000 is in the second position P2, with its elastic arm 313 inserted into the bottom 1252 of the slot 125; the remaining reloading components 300 are in the first position P1, with their elastic arms 313 inserted into the opening 1251 of the slot 125. When the right-side reloading unit 3000 slides from the first position P1 to the second position P2, it triggers the left-side reloading unit 3000 to reset from the second position P2 to the first position P1. At this time, the elastic arm 313 of the left-side reloading unit 3000 resets from the bottom 1252 of the slot 125 to the opening 1251 of the slot 125, and the elastic arm 313 of the right-side reloading unit 3000 inserts from the opening 1251 of the slot 125 into the bottom 1252 of the slot 125.

[0076] In one embodiment, see Figure 3 The axial direction of the slot 125 is parallel to the axial direction of the atomizing device. The slot 125 includes a slot opening 1251 and a slot bottom 1252, which are connected along the axial direction of the atomizing device. The inner diameter of the slot opening 1251 is larger than the inner diameter of the slot bottom 1252, and the inner diameter of the slot opening 1251 is larger than the sum of the cross-sectional areas of the elastic arms 313 of each cartridge replacement unit 3000, so that the elastic arms 313 of each cartridge replacement unit 3000 can be inserted into the slot opening 1251. When the cartridge replacement unit 3000 slides from the first position P1 to the second position P2, due to the elastic deformation capability of the elastic arm 313, the elastic arm 313 can be inserted from the edge of the slot opening 1251 of the slot 125 to the center of the slot bottom 1252, thereby occupying the position of the slot bottom 1252 of the slot 125.

[0077] In one embodiment, see Figure 3 , Figure 6 and Figure 8 The cartridge replacement unit 3000 extends with a connecting arm 314. An elastic arm 313 is integrally connected to the connecting arm 314. The elastic arm 313 extends along the axial direction of the atomizing device. The connecting arm 314 is perpendicular to or at an angle to the elastic arm 313. The elastic arm 313 is inserted into a slot 125. A clearance groove 1221 is formed in the wall of the slot 125, extending along the axial direction of the atomizing device and penetrating the top end face of the slot wall. When the elastic arm 313 slides in the slot 125, the connecting arm 314 slides in the clearance groove 1221. The connecting arm 314 allows the elastic arm 313 to be inserted into the slot 125 along the axial direction of the atomizing device.

[0078] In one embodiment, see Figure 3The slot 125 is located at the center of each reloading unit 3000, that is, each reloading unit 3000 is surrounded in the slot 125. The elastic arm 313 is formed on the side of the reloading unit 3000 facing the slot 125. After the slot 125 and each reloading unit 3000 are assembled, the elastic arm 313 of each reloading unit 3000 is inserted into the slot 125 respectively.

[0079] In one embodiment, see Figure 3 and Figure 8 The slot 125 is formed at the center of the first bracket 120. Since the first bracket 120 is snapped and fixed in the main housing 110, the position of the slot 125 remains fixed, so that when the replacement unit 3000 slides, it can slide from the slot opening 1251 to the slot bottom 1252, or from the slot bottom 1252 to the slot opening 1251.

[0080] In one embodiment, see Figure 8 The first support 120 includes a first surrounding plate 121, a first central column 122, and a plurality of first partitions 123. The first surrounding plate 121 surrounds the periphery of the first central column 122 and is attached to the inner circumferential wall of the main housing 110 and engaged by a first locking block 124 and a first locking groove 1112. The first partitions 123 are distributed sequentially at intervals along the circumference of the first central column 122 and are respectively connected between the first central column 122 and the first surrounding plate 121. A slot 125 is formed at the top center of the first central column 122. The first surrounding plate 121 and the first partitions 123 enclose a plurality of insertion spaces for the atomizer 2 to pass through. In addition, the first central column 122 can also abut against the end of the limiting member 350 opposite to the rotating reset member 370, so as to form an axial limiting together with the rotating reset member 370 in the limiting member 350.

[0081] In one embodiment, see Figure 7 In the inner cavity of the main housing 110, a third partition 1115 is formed at the position corresponding to each of the first partitions 123. Each of the first partitions 123 and each of the third partitions 1115 are one-to-one and abut against each other along the axial direction of the atomizing device. In this way, the inner peripheral wall of the main housing 110, each of the third partitions 1115, each of the first partitions 123 and the first central column 122 together form a circumferential limit on the cartridge changing unit 3000 to ensure the sliding stability of the cartridge changing unit 3000.

[0082] In one embodiment, see Figure 2 and Figure 3The nozzle assembly 200 has a first air outlet 211 and a plurality of air outlet channels 221 respectively connected to the first air outlet 211. Each air outlet channel 221 is connected to the first air outlet 211. The cartridge replacement unit 3000 includes an air outlet pipe 315, which is connected to the second air outlet 21 of the atomizer 2. The air outlet pipe 315 is slidably inserted into the air outlet channel 221 and is connected to the first air outlet 211.

[0083] In this embodiment, during the sliding process of the cartridge replacement unit 3000, each air outlet pipe 315 is configured in a one-to-one correspondence with each air outlet channel 221. The air outlet pipe 315 slides in the air outlet channel 221, and the air outlet pipe 315 always remains connected to the first air outlet 211, so that each atomizer 2 always remains connected to the first air outlet 211, without the need to switch the air outlet state of the atomizer 2.

[0084] In one embodiment, see Figure 2 and Figure 3 The nozzle assembly 200 includes a nozzle 210 and a nozzle seal 220. A first air outlet 211 is formed in the nozzle 210, and each air outlet 221 is formed in the nozzle seal 220. The nozzle seal 220 is press-fitted between the inner side of the nozzle 210 and the main housing 110 of the power assembly 100. Please refer to [link / reference]. Figure 3 and Figure 8 The main housing 110 is provided with mounting ports 1113 for each air outlet pipe 315. Each air outlet pipe 315 is correspondingly arranged with each air outlet channel 221 of the mouthpiece seal 220. The air outlet pipe 315 is inserted into the air outlet channel 221 of the mouthpiece seal 220 through the mounting port 1113. The mouthpiece seal 220 ensures the sealing of the connection between the mouthpiece 210 and the main housing 110, and ensures the sealing of the insertion of the air outlet pipes 315, thereby ensuring the sealing of the communication between the second air outlet 21 of the atomizer 2 and the first air outlet 211 of the mouthpiece 210.

[0085] In one embodiment, see Figure 3 Each nozzle seal 220 has a flange 222 extending from the position of each mounting port 1113. The flange 222 surrounds the end face of the air outlet 221. Each flange 222 is sealed and inserted into the mounting port 1113. The air outlet pipe 315 is inserted into the air outlet 221 via the flange 222.

[0086] In another embodiment of this application, it can also be designed so that only the atomizer 2 in the usage position is connected to the first air outlet 211 at any given time. Specifically, the air outlet pipe 315 is disconnected from the first air outlet 211 in the first position P1; the air outlet pipe 315 is connected to the first air outlet 211 in the second position P2. That is, only when the air outlet pipe 315 is in the second position P2 can the air outlet pipe 315 be connected to the first air outlet 211, and only then can the atomizer 2 be connected to the first air outlet 211 through the air outlet pipe 315, thereby ensuring that only the air outlet of the atomizer 2 in the usage position can be connected. This can reduce cross-contamination of flavors between the atomizers 2.

[0087] For details, please refer to Figure 10 The air outlet 221 includes a first air outlet section 2211 and a second air outlet section 2212. The first air outlet section 2211 and the second air outlet section 2212 are connected through an interface 2213. The air outlet pipe 315 is connected to the first air outlet 211. The air outlet pipe 315 is inserted into the first air outlet section 2211. When the air outlet pipe 315 is in the first position P1, the air outlet pipe 315 blocks the interface 2213, and the atomizer 2 is disconnected from the first air outlet 211. When the air outlet pipe 315 is in the second position P2, the air outlet pipe 315 is offset from the interface 2213, and the air outlet pipe 315 can be connected to the second air outlet section 2212 through the interface 2213, thereby connecting the atomizer 2 to the first air outlet 211.

[0088] In one embodiment, see Figure 3 and Figure 6 The cartridge replacement unit 3000 includes an air outlet connector 310, which includes a sleeve portion 311 and an air outlet pipe 315. The sleeve portion 311 is fitted onto the outside of the end of the atomizer 2 near the mouthpiece 210. The air outlet pipe 315 passes through the center of the end of the sleeve portion 311 facing the mouthpiece 210 and is integrally connected to the sleeve portion 311. One end of the air outlet pipe 315 is inserted into the air outlet channel 221, and the other end of the air outlet pipe 315 is press-fitted into the mouthpiece 210, thereby forming a sealed connection between the air outlet pipe 315 and the second air outlet 21.

[0089] Please see Figure 2 The atomizer 2 has an outlet seal 22 corresponding to the second outlet 21. Specifically, the other end of the outlet pipe 315 is inserted into the outlet seal 22 to form a sealed connection between the outlet pipe 315 and the second outlet 21. Simultaneously, the interference fit between the outlet pipe 315 and the outlet seal 22 establishes the positioning and connection between the outlet connector 310 and the atomizer 2, allowing the outlet connector 310 to slide within the power assembly 100. It is understood that in other embodiments of this application, where structurally permissible, the sleeve 311 may cover the entire axial position of the atomizer 2; this is not a unique limitation.

[0090] In one embodiment, see Figure 5 A mating portion 312 is formed on the outer wall of the sleeve portion 311 facing the limiting member 350. A connecting arm 314 and an elastic arm 313 are formed on the outer wall of the sleeve portion 311 facing the slot 125. The mating portion 312 and the elastic arm 313 are spaced apart along the axial direction of the atomizing device, so that the mating portion 312 and the elastic arm 313 can respectively mate with the slot 125 and the limiting member 350 which abut against each other along the axial direction of the atomizing device.

[0091] In one embodiment, see Figures 2 to 4 The cartridge changing unit 3000 also includes a slider 320, which is at least partially exposed outside the power supply assembly 100. By sliding the slider 320, the cartridge changing unit 3000 can be moved within the power supply assembly 100. By sliding the slider 320 outside the power supply assembly 100, the cartridge changing unit 3000 and the atomizer 2 can be moved along the axial direction of the atomizing device within the power supply assembly 100, allowing the atomizer 2 to switch between the active and inactive positions, making operation convenient.

[0092] Specifically, the slider 320 is connected to the air outlet connector 310, and the air outlet connector 310 and the atomizer 2 are moved by sliding the slider 320.

[0093] In one embodiment, see Figure 3 and Figure 8 The sliding button 320 includes a sliding plate 321 slidably disposed outside the main housing 110 and a hook 322 formed on the sliding plate 321. A sliding groove 1114 is formed on the side wall of the main housing 110, and a second locking groove 3111 is formed on the side wall of the sleeve portion 311. The hook 322 is engaged in the second locking groove 3111 via the sliding groove 1114, thereby forming a connection between the sliding button 320 and the sleeve portion 311. During the sliding of the sliding button 320, the connecting part between the hook 322 and the sliding plate 321 can slide in the sliding groove 1114, which not only guides the sliding of the sliding button 320, but also ensures the stability of the sliding of the sliding button 320. It is understood that in other embodiments of this application, the sliding button 320 and the sleeve portion 311 can also be connected by other means, such as interference fit, welding, or locking connection by fasteners.

[0094] In one embodiment, see Figure 3 Two hooks 322 are formed on the slide plate 321, and a positioning post 323 is provided between the two hooks 322. A positioning hole 3112 is formed on the side wall of the sleeve part 311. The positioning post 323 is inserted into the positioning hole 3112 to form a positioning between the slide button 320 and the sleeve part 311.

[0095] In one embodiment, see Figure 1 The main housing 110 has a roughly square cross-section and can accommodate four atomizers 2 arranged in a square shape. Four sliding buttons 320 are provided on the surface of the main housing 110, each sliding button 320 being located at one of the four corners of the main housing 110, and the four corners of the main housing 110 are rounded. In this arrangement, the sliding buttons 320 are not located on the side walls of the main housing 110, but rather at the corners, thus avoiding any obtrusive appearance and ensuring that the placement of the sliding buttons 320 does not affect the overall aesthetics of the atomizing device. It is understood that in other embodiments of this application, the main housing 110 may also have other shapes, such as circular, elliptical, flat, or other irregular shapes; the main housing 110 may accommodate two, three, five, or more atomizers 2, which may be arranged in a circular or irregular shape. Of course, the sliding buttons 320 may also be located on the side of the main housing 110; this is not a limitation.

[0096] In one embodiment, see Figure 2 and Figure 11 The cartridge replacement unit 3000 also includes an air intake pipe 331 connected to the atomizer 2; the power supply assembly 100 has an air intake channel 1321; the air intake pipe 331 is disconnected from the air intake channel 1321 when it is in the first position P1, and connected to the air intake channel 1321 when it is in the second position P2.

[0097] Specifically, when the air intake pipe 331 is in the first position P1, it is disconnected from the air intake channel 1321, thus disconnecting the atomizer 2 in the non-use position from the air intake channel 1321; when the air intake pipe 331 is in the second position P2, it is connected to the air intake channel 1321, thus connecting the atomizer 2 in the use position to the air intake channel 1321, thereby ensuring that only the atomizer 2 in the use position has air intake connection, preventing cross-contamination of flavors between the atomizers 2.

[0098] In one embodiment, see Figure 2 and Figure 11 The cartridge replacement unit 3000 includes an air intake connector 330, which is at least sleeved on the end of the atomizer 2 away from the mouthpiece assembly 200 and abuts against the atomizer 2 along the axial direction of the atomizing device. When the atomizer 2 slides down, it can drive the air intake connector 330 to slide down. The air intake connector 330 includes an air intake pipe 331.

[0099] In one embodiment, see Figure 2 and Figure 11The power supply assembly 100 includes a second bracket 130 and an assembly seal 140. The second bracket 130 is fixedly installed in the main housing 110. The second bracket 130 forms an installation cavity 1311 and an air intake duct 1321. The air intake duct 1321 is connected to the bottom of the installation cavity 1311. The assembly seal 140 is interference-fitted into the installation cavity 1311. The assembly seal 140 and the second bracket 130 together form an air chamber 133, which communicates with the air intake duct 1321. The air intake connector 330 is slidably disposed in the mounting cavity 1311. When the air intake pipe 331 is in the first position P1, the air intake pipe 331 is sealed in the assembly seal 140, and the air intake pipe 331 is not connected to the air chamber 133, thereby preventing the air intake pipe 331 from connecting with the air intake channel 1321. When the air intake pipe 331 is in the second position P2, the air intake pipe 331 is inserted into the air chamber 133 and connects with the air chamber 133, thereby connecting the air intake pipe 331 with the air intake channel 1321. In this embodiment, the second bracket 130 can support the assembly seal 140 for installation and form the air intake channel 1321 and the mounting cavity 1311, and can also support and guide the sliding of the air intake connector 330. In addition, the assembly seal 140 can form a sealed connection between the air intake pipe 331 and the air intake channel 1321, ensuring that the atomizer 2 and the air intake channel 1321 are sealed and connected.

[0100] In one embodiment, see Figure 11 and Figure 12 The end of the air intake pipe 331 facing away from the nozzle 210 is closed, and a first through hole 3311 is formed on the side wall of the air intake pipe 331. The mounting seal 140 forms an insertion hole 141 corresponding to each air intake pipe 331, and the air intake pipe 331 is slidably inserted into the insertion hole 141. When the air intake pipe 331 is in the first position P1, the first through hole 3311 of the air intake pipe 331 abuts against the inner wall of the mounting seal 140, and the air intake pipe 331 is not connected to the air chamber 133. When the air intake pipe 331 is in the second position P2, the air intake pipe 331 extends into the air chamber 133, and the first through hole 3311 of the air intake pipe 331 is connected to the air chamber 133, thereby forming a connection between the air intake pipe 331 and the air intake channel 1321.

[0101] Optionally, the number of first through holes 3311 can be one or more, and each first through hole 3311 is distributed sequentially at intervals along the circumference of the intake pipe 331. It can be understood that in other embodiments of this application, each first through hole 3311 may also be distributed along the axial direction of the intake pipe 331, or each first through hole 3311 may be distributed along both the axial and circumferential directions of the intake pipe 331.

[0102] In addition, a sealing ring 1411 is provided on the inner wall of the insertion hole 141. The sealing ring 1411 abuts against the outer peripheral wall of the air intake pipe 331, thereby ensuring the sealing performance of the insertion between the air intake pipe 331 and the assembly seal 140.

[0103] In one embodiment, see Figure 11 , Figure 13 and Figure 14 The second bracket 130 includes a main body 131 and an extension tube 132. A mounting cavity 1311 is formed in the main body 131. The outer peripheral wall of the main body 131 is fitted and interlocked with the inner peripheral wall of the main housing 110. A second through hole is formed at the bottom of the main body 131. The extension tube 132 extends from the bottom of the main body 131 in a direction away from the main body 131, corresponding to the position of the second through hole. An air intake duct 1321 is formed in the extension tube 132 and communicates with the mounting cavity 1311 through the second through hole. An assembly seal 140 is interference-fitted into the main body 131, and the outer peripheral wall of the assembly seal 140 is interference-fitted with the inner peripheral wall of the main body 131.

[0104] In one embodiment, see Figure 11 The power supply assembly 100 also includes a bottom cover 113, which is installed at the bottom opening of the main housing 110. A first air inlet 1131 is formed on the bottom cover 113, which is connected to the air inlet 1321. External air enters the atomizer 2 through the first air inlet 1131, the air inlet 1321, the air chamber 133 and the air inlet pipe 331.

[0105] In one embodiment, see Figure 11 and Figure 15 A sealing sleeve 150 is abutted between the bottom cover 113 and the extension tube 132. The sealing sleeve 150 is fitted outside the extension tube 132 and is interference-fitted with the bottom cover 113, thereby forming a sealed connection between the first air inlet 1131 and the air intake duct 1321.

[0106] In one embodiment, see Figure 13 and Figure 15 The second bracket 130 includes two extension tubes 132, which are spaced apart and connected to the main body 131. A sealing sleeve 150 abuts between the two extension tubes 132 and the bottom cover 113. The sealing sleeve 150 has two third connection ports 151 corresponding to the two extension tubes 132, which are connected to two air intakes 1321. The bottom cover 113 has a first air intake 1131 corresponding to one of the extension tubes 132 and a through groove corresponding to the other extension tube 132. An air regulating switch 160 is installed in the through groove and slides in it. A second air hole 161 is formed on the air regulating switch 160. By sliding the air regulating switch 160, the mating area between the second air hole 161 and the third connection port 151 is adjusted, thereby adjusting the air intake volume.

[0107] In one embodiment, see Figure 11 and Figure 14 The bottom center of the main body 131 is provided with a mounting post 134, and the center of the assembly seal 140 is formed with a mounting hole (not shown in the figure). The assembly seal 140 is sleeved on the mounting post 134 through the mounting hole.

[0108] In one embodiment, see Figure 11 and Figure 14 The main body 131 has multiple limiting blocks 135 protruding from its bottom periphery. The periphery of the mounting seal 140 facing away from the nozzle 210 abuts against each limiting block 135. The main body 131 is also equipped with a pressing member 170, which presses against the side of the mounting seal 140 facing away from the limiting blocks 135. The pressing member 170 is engaged with the main body 131. The pressing member 170 and the limiting blocks 135 limit the mounting seal 140 along the axial direction of the atomizing device.

[0109] In one embodiment, see Figure 11 and Figure 12 The air intake connector 330 also includes a base plate 332 and a second enclosure plate 333. A third through hole 3321 is formed on the base plate 332. An air intake pipe 331 extends from the side of the base plate 332 away from the mouthpiece 210 towards the mouthpiece 210, and the air intake pipe 331 communicates with the third through hole 3321. The second enclosure plate 333 extends from the edge of the base plate 332 away from the air intake pipe 331 towards the mouthpiece 210. After assembly, the end of the atomizer 2 with the second air intake port abuts against the base plate 332, and the second air intake port of the atomizer 2 communicates with the air intake pipe 331 through the third through hole 3321. Additionally, the second enclosure plate 333 also serves to circumferentially limit the end of the atomizer 2 with the second air intake port to ensure the axial sliding stability of the atomizer 2.

[0110] In one embodiment, see Figure 11 and Figures 16 to 18 The pressure member 170 includes a second central post 171 and a plurality of second partitions 172. The second central post 171 abuts against the assembly seal 140. Each second partition 172 is distributed around the second central post 171. One end of each second partition 172 is integrally connected to the second central post 171, and the other end of each second partition 172 abuts against the inner wall of the main body 131. The second central post 171, two adjacent second partitions 172, and the main body 131 together enclose an active space for the functional limiting air intake docking member 330. The outer wall of the air intake docking member 330 is slidably fitted to the second central post 171 and two adjacent second partitions 172, thereby allowing the air intake docking member 330 to be circumferentially limited and axially slidably guided by the second central post 171 and the two second partitions 172.

[0111] In one embodiment, see Figures 16 to 18The pressing component 170 also includes a plurality of first abutting plates 173, each first abutting plate 173 being formed on the side of each second partition 172 away from the bottom plate 332. The first abutting plates 173 extend from the opposite sides of the second partition 172 toward the sliding cavity. In this way, the first abutting plates 173 can limit the sliding of the air intake docking component 330 toward the suction nozzle 210, preventing the air intake docking component 330 from sliding out of the main body 131.

[0112] In one embodiment, see Figure 14 , Figures 16 to 18 The pressing component 170 also includes a second abutment plate 174, which is formed on the side of the second partition plate 172 facing away from the second central post 171. A top-through receiving groove 1314 is formed on the inner wall of the main body 131 corresponding to the position of the second abutment plate 174. A second locking block 1741 is formed on the second abutment plate 174, and a third locking groove 1312 is formed on the inner wall of the main body 131. During assembly, the second abutment plate 174 is inserted into the receiving groove 1314 from the end of the main body 131 facing the suction nozzle 210 until the second locking block 1741 engages with the third locking groove 1312, thereby ensuring the installation stability of the pressing component 170 in the main body 131.

[0113] Optionally, a second abutment plate 174 may be provided on each of the second partitions 172, or a second abutment plate 174 may be provided on some of the second partitions 172.

[0114] In one embodiment, see Figure 12 , Figure 14 and Figure 18 The air intake connector 330 also includes a limiting plate 334, which extends from the bottom plate 332 away from the side of the air intake pipe 331. The limiting plate 334 is positioned opposite to the second enclosure plate 333. The main body 131 forms a limiting groove 1313 corresponding to the position of the limiting plate 334. The limiting plate 334 slides along the axial direction of the atomizing device and is inserted into the limiting groove 1313. The limiting plate 334 and the limiting groove 1313 can guide and limit the axial sliding of the air intake connector 330.

[0115] In one embodiment, see Figure 11 The base plate 332 has a recessed mounting groove 3322 on the side opposite to the air intake pipe 331. An air intake seal 340 is installed in the mounting groove 3322. The air intake seal 340 has a second connection port 341 and abuts against the base plate 332 and the atomizer 2. The second connection port 341 connects the second air intake port and the third through hole 3321. The air intake seal 340 ensures the sealing of the connection between the air intake pipe 331 and the atomizer 2.

[0116] In one embodiment, see Figure 11, Figure 12 , Figure 14 and Figure 17 The air intake connector 330 also includes a plug post 335. A plug tube 136 protrudes from the second bracket 130. The axial reset member 360 is a cylindrical spring, housed within the plug tube 136. The plug post 335 is inserted into the plug tube 136, and the axial reset member 360 is sleeved on the plug post 335. The axial reset member 360 abuts against the bottom of the plug post 335 and the plug tube 136 along the axial direction of the atomizing device. This insertion of the plug post 335 and the plug tube 136 increases the sliding stability of the air intake connector 330 within the second bracket 130. It also positions and compresses the axial reset member 360, ensuring stable extension and contraction along the axial direction of the atomizing device. Understandably, in other embodiments of this application, the axial reset member 360 may also be a spring clip, or it may directly abut against the air intake connector 330 and the second bracket 130; this is not a limiting factor.

[0117] In another embodiment of this application, the air intake pipe 331 and the air intake channel 1321 can always be kept in communication. In this case, it is not necessary to close the end of the air intake pipe 331 away from the nozzle 210, so as to ensure that the air intake pipe 331 and the air intake channel 1321 are always in communication.

[0118] In one embodiment, see Figure 17 and Figure 18 The power supply assembly 100 includes multiple sets of electrodes 181, each set of electrodes 181 corresponding to one atomizer 2. Atomizer 2 in the usage position is electrically connected to its corresponding electrode 181. In other words, only atomizer 2 in the usage position can be powered, thereby heating and atomizing its internal atomizing medium to form an aerosol; other atomizers 2 not in the usage position cannot be powered. In this embodiment, by sliding the atomizer 2 along the axial direction of the atomizing device to establish or disconnect the electrical connection between the atomizer 2 and the electrode 181, not only is precise axial alignment of the electrode 181 and the atomizer 2 ensured, but the sliding of the atomizer 2 also prevents friction with the electrode 181, thus preventing wear on the electrode 181.

[0119] In one embodiment, see Figure 17 and Figure 18 Each set of electrodes 181 is mounted on the second bracket 130, and the second bracket 130 is fixedly mounted in the main housing 110, thereby ensuring that the position of each set of electrodes 181 is fixed. The connection between the electrode 181 and the atomizer 2 can be switched by simply sliding the atomizer 2.

[0120] In one embodiment, see Figure 14 and Figure 18The second support 130 has multiple electrode mounting portions 137, and each group of electrodes 181 is mounted on the electrode mounting portion 137. Specifically, the electrode 181 is an electrode post, and the electrode mounting portion 137 protrudes from the bottom wall of the main body 131 and is cylindrical.

[0121] In one embodiment, see Figure 2 The power supply assembly 100 also includes an electronic control unit 180, which includes a circuit board 182 and a battery 183. The battery 183 is electrically connected to the circuit board 182. The battery 183 and the circuit board 182 are installed in the main housing 110 and located between the bottom cover 113 and the second bracket 130. The electrode mounting portion 137 has mounting holes 142 extending axially through both ends. The electrode 181 is installed in the mounting holes 142, and the bottom end of the electrode 181 is electrically connected to the circuit board 182 through a wire.

[0122] In one embodiment, the assembly seal 140 has clearance holes at the positions of each electrode mounting part 137 and each positioning post 323, and the assembly seal 140 is interference-fitted onto each electrode mounting part 137 and each positioning post 323.

[0123] In one embodiment, see Figure 11 The power supply assembly 100 also includes an airflow sensor 184, which is electrically connected to the circuit board 182. The airflow sensor 184 is connected to the air intake 1321, the air chamber 133, or the air intake pipe 331. The airflow sensor 184 is used to detect the airflow when the user inhales through the mouthpiece 210 and feeds the detection result back to the circuit board 182. The circuit board 182 powers the atomizer 2 through the electrode 181, thereby causing the atomizer 2 to heat and atomize to form an aerosol.

[0124] In one embodiment, see Figure 11 The mounting post 134 has a receiving cavity on the side opposite to the mounting cavity 1311. The receiving cavity is connected to the air cavity 133 through the side wall of the mounting post 134. The airflow sensor 184 is installed in the receiving cavity. The airflow sensor 184 can detect the airflow in the air cavity 133 and feed it back to the circuit board 182.

[0125] Specifically, the sidewall of the mounting column 134 is provided with a plurality of fourth air holes 1341 arranged circumferentially. Each fourth air hole 1341 is connected to the accommodating cavity. An airflow sealing element 185 is installed in the accommodating cavity. An airflow sensor 184 is installed in the airflow sealing element 185 and is connected to the accommodating cavity through the airflow sealing element 185.

[0126] In one embodiment, see Figure 1The main housing 110 includes an upper housing 111 and a lower housing 112, which are vertically joined together. A bottom cover 113 is snapped into the lower housing 112, and a nozzle assembly 200 is snapped into the upper housing 111. A first bracket 120 and a second bracket 130 are respectively installed in the upper housing 111 and the lower housing 112. The first bracket 120 is snapped into the upper housing 111, and the second bracket 130 is snapped into both the upper housing 111 and the lower housing 112, thus forming a secure connection between the upper housing 111 and the lower housing 112. After assembly, the first bracket 120 and the second bracket 130 abut against each other along the axial direction of the atomizing device, and the first bracket 120 abuts against the pressure member 170.

[0127] In one embodiment, see Figure 14 The sidewall of the second bracket 130 includes an elastic portion 139, on which a third locking block 1392 is formed. A fourth locking groove 1116 is formed on the upper housing 111, and the third locking block 1392 engages with the fourth locking groove 1116. Furthermore, the elastic portion 139 has a protruding protrusion 1391, and the lower housing 112 has a relief groove corresponding to the position of the protrusion 1391. The protrusion 1391 extends to the outside via the relief groove, allowing the user to press the protrusion 1391 from the outside, thereby unlocking the engagement between the second bracket 130 and the upper housing 111.

[0128] On the other hand, this application also provides an aerosol generating device, including a plurality of atomizers 2 and an atomizing device, with at least one atomizer 2 housed in the atomizing device. Through the aforementioned atomizing device arrangement, this aerosol generating device can carry multiple atomizers 2, and can carry atomizers 2 with different flavors, thereby meeting the needs of different users for large inhalations and multiple flavors. In use, one or more atomizers 2 can be placed in the atomizing device.

[0129] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
