[0059] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] The terms "first", "second" and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or suggesting relative importance or implicitly indicating the quantity or order of the indicated technical features. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative position relationship or movement situation between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or equipment that includes a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.

[0061] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0062] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0063] Please refer to Figure 1 and Figure 2 The present application provides an embodiment of a power supply component 1 and an aerosol generating device 100 including the power supply component 1. The aerosol generating device 100 is a device capable of generating aerosol. The aerosol generating device 100 includes a power supply component 1 and an atomization component 2.

[0064] The atomizing assembly 2 includes one or more atomizers 21. The atomizer 21 may include one or more heating elements for releasing heat to heat the aerosol-forming substrate, causing the aerosol-forming substrate to generate an aerosol. The atomizer may also include one or more ultrasonic elements capable of high-frequency vibration under ultrasonic drive. The atomizer utilizes ultrasonic vibrations to atomize the aerosol-forming substrate to form an aerosol. Of course, the atomizer may also include other electrical components capable of generating an aerosol from the aerosol-forming substrate.

[0065] The atomizer 21 may also include a power-taking electrode electrically connected to an electrical element that causes the aerosol-generating matrix to generate an aerosol. The number of power-taking electrodes in an atomizer 21 may be at least 2. The atomizer 21 is electrically connected to the power supply component 1 through the power-taking electrode so that one or more electrical elements obtain voltage, current or electric power, and then the one or more electrical elements work to cause the aerosol-generating matrix to generate an aerosol.

[0066] The power supply assembly 1 includes A power supply electrodes 11. The power supply assembly 1 provides voltage, current, or electric power to an atomizer electrically connected thereto through at least some of the A power supply electrodes 11. A is an integer greater than 1. For example, A may be equal to 3.

[0067] It should be noted that, as described in this application, "a plurality of" refers to a number of two or more. Figure 4 and Figure 5 In the embodiment shown, the atomizing assembly includes two atomizers; or, in the embodiment shown Figure 8 and Figure 9 In the embodiment shown, the atomization assembly includes three atomizers.

[0068] In some embodiments, the atomizer 21 further includes a cup body 211, a storage chamber disposed within the cup body 211, and an aerosol-generating substrate stored in the storage chamber. The aerosol-generating substrates stored in the storage chambers of at least two atomizers 21 in the atomizer assembly 2 may be different. All atomizers 21 in the same atomizer assembly 2 may store the same aerosol-generating substrate. Different aerosol-generating substrates may have different flavors or fragrances.

[0069] In some embodiments, the aerosol-generating substrate may comprise a solid, the aerosol-generating substrate may comprise a paste, or the aerosol-generating substrate may comprise a liquid.

[0070] The aerosol-generating matrix may contain nicotine, which may include nicotine or nicotine salt. Nicotine has a nerve stimulating effect and is used to bring the user a sense of pleasure when smoking.

[0071] The aerosol-generating matrix may include a cooling agent, which can make the aerosol refreshing and cooling, thereby enhancing the throat-soothing effect. Cooling agents include, but are not limited to, at least one of N,2,3-trimethyl-2-isopropylbutyramide (WS-23), menthol, peppermint oil, and N-ethyl-p-menthyl-3-carboxamide (WS-3).

[0072] The aerosol-generating matrix may include a sweetener to enhance the sweetness of the aerosol and improve its flavor. Sweeteners include, but are not limited to, N-[N-(3,3-dimethylbutyl)]-L-α-aspartame-L-phenylalanine 1-methyl ester (also known as neotame). Sweeteners may also include, but are not limited to, one or more of sucralose, steviol glycosides, neotame, acesulfame potassium, aspartame, glycyrrhizin, saccharin sodium, cyclamate, and monk fruit sweetener.

[0073] The aerosol-generating matrix may include tobacco extract. The main components of tobacco extract include tobacco cellulose, tobacco leaf protein, and other substances with tobacco aroma, but do not contain nicotine or nicotine-like substances. Tobacco extract can enhance the similarity of smoke to traditional cigarette smoke, giving the aerosol a traditional cigarette flavor.

[0074] The aerosol-generating matrix may contain a flavoring agent that can reduce the irritation caused by the tobacco extract. The flavoring agent may include at least one of 2-acetylpyrazine, ethyl maltol, and methyl dihydrojasmonate. The flavoring agent may also include a throat-soothing ingredient. Such throat-soothing ingredients include, but are not limited to, at least one of eugenol, clove leaf oil, clove bud oil, Peruvian balsam oil, fenugreek tincture, star anise oil, vanilla bean tincture, tea polyphenols, lemon oil, and propylene glycol.

[0075] At least a portion of the wall of the cup body 211 may allow vision to pass through, or a window may be provided on the wall of the cup body 211 to allow the user to observe the amount of the aerosol-generating substrate in the storage cavity.

[0076] In some embodiments, the nebulizer 21 is provided with an air guide channel 212, which is used to guide the aerosol out of the nebulizer 21. The air guide channel 212 may pass through the storage cavity.

[0077] In some embodiments, reference may be made to Figure 6 The aerosol-generating substrate stored in the atomizer 21 is primarily liquid. The atomizer 21 may further include a liquid reservoir 213 disposed within the storage chamber. The liquid reservoir 213 is configured to absorb the liquid aerosol-generating substrate, thereby confining the liquid aerosol-generating substrate within the storage chamber within the liquid reservoir 213 and thereby preventing leakage of the liquid aerosol-generating substrate from the storage chamber. It should be noted that the liquid reservoir 213 is optional and not mandatory.

[0078] In some embodiments, the aerosol-generating substrate stored in the atomizer 21 is primarily liquid. The atomizer assembly 2 may include an adsorption element 214 and a heating element 215, with the heating element 215 disposed on the adsorption element 214. The adsorption element 214 may be a porous body for directing the liquid substrate into the heating range of the heating element. The porous body may be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body may be a porous ceramic or porous metal. The present application does not limit the structure and composition of the porous body.

[0079] It should be noted that it is optional for each atomizer 21 to include a storage chamber. In other embodiments, the aerosol generating device may include a common storage chamber, and multiple atomizers 21 may be in fluid communication with the common storage chamber, so that the heating elements 215 in the multiple atomizers 21 can cause the aerosol-generating substrate in the common storage chamber to evaporate into aerosol. The multiple atomizers 21 are independent of each other, and therefore the heating elements in the multiple atomizers 21 are independent of each other. Therefore, the amount of aerosol generated by the aerosol generating device can be changed by changing the atomizer 21 involved in atomizing the aerosol-generating substrate, or by increasing or decreasing the number of atomizers 21 involved in atomizing the aerosol-generating substrate.

[0080] The types of atomizer assemblies 2 include at least a first atomizer assembly 3 and a second atomizer assembly 4. The power supply assembly 1 is configured to be adaptable to the first atomizer assembly 3 and to provide electrical power to the first atomizer assembly 3, and also to be adaptable to the second atomizer assembly 4 and to provide electrical power to the second atomizer assembly 4. Therefore, the aerosol generating device 100 can include either the first atomizer assembly 3 or the second atomizer assembly 4.

[0081] The first atomizer assembly 3 and the second atomizer assembly 4 can be electrically connected to the power supply assembly 1 in a mutually exclusive manner. The first atomizer assembly 3 and the second atomizer assembly 4 cannot be electrically connected to the power supply assembly 1 at the same time. The first atomizer assembly 3 can replace the second atomizer assembly 4 in being electrically connected to the power supply assembly 1, and the second atomizer assembly 4 can also replace the first atomizer assembly 3 in being electrically connected to the power supply assembly 1. Thus, either the first atomizer assembly 3 or the second atomizer assembly 4 can be selected to be electrically connected to the power supply assembly 1.

[0082] For ease of description, the atomizer included in the first atomizer assembly 3 is defined as the first atomizer 31, and the atomizer included in the second atomizer assembly 4 is defined as the second atomizer 41. Furthermore, the heating element and power extraction electrode included in the first atomizer 31 are defined as the first heating element 311 and the first power extraction electrode 312, respectively; the heating element and power extraction electrode included in the second atomizer 41 are defined as the second heating element 411 and the second power extraction electrode 412, respectively.

[0083] The first heating element 311 and the second heating element 411 may have substantially the same heating resistance. The first heating element 311 and the second heating element 411 may have substantially the same heating area or heating track. The first heating element 311 and the second heating element 411 may both comprise a mesh structure.

[0084] The first atomizer 31 and the second atomizer 41 have different structural features. Specifically, the first heating elements 311 have M elements, and the first power-collecting electrodes 312 have B elements. The second heating elements 411 have N elements, and the first power-collecting electrodes 412 have C elements. Here, B and C are both integers greater than 1, with C < B ≤ A; M and N are both integers greater than 0, with M ≥ 2.

[0085] When the first atomizer 31 is electrically connected to the power supply assembly 1, the B first power-collecting electrodes 312 abut against the B power supply electrodes 11 in the power supply assembly in a one-to-one correspondence, and the first heating element 311 can release heat to cause the aerosol-generating substrate to generate an aerosol. Preferably, the first heating element 311 can release heat to cause the aerosol-generating substrate stored in the first atomizer 31 to generate an aerosol.

[0086] When the second atomizer 41 is electrically connected to the power supply assembly 1, the C second power-collecting electrodes 412 abut against the C power supply electrodes 11 in the power supply assembly 1 in a one-to-one correspondence, and the second heating element 411 can release heat to cause the aerosol-generating substrate to generate an aerosol. Preferably, the second heating element 411 can release heat to cause the aerosol-generating substrate stored in the second atomizer 41 to generate an aerosol.

[0087] N may be less than M, or the number of first heating elements 311 in the first atomizer 31 may be greater than the number of second heating elements 411 in the second atomizer 41. N may be equal to M, or the number of first heating elements 311 in the first atomizer 31 may be equal to the number of second heating elements 411 in the second atomizer 41. N may be greater than M, or the number of first heating elements 311 in the first atomizer 31 may be less than the number of second heating elements 411 in the second atomizer 41.

[0088] In some embodiments, the M first heating elements 311 in the first atomizer 31 simultaneously heat the aerosol-generating substrate. Compared to the N second heating elements 411 in the second atomizer 41 simultaneously heating the aerosol-generating substrate, the amount of aerosol generated per unit time by the first atomizer 31 is greater than the amount of aerosol generated per unit time by the second atomizer 41. Therefore, the first atomizer 31 and the second atomizer 41 can provide different sensory experiences for the user.

[0089] In some embodiments, the rated power of the first nebulizer 31 is greater than the rated power of the second nebulizer 41 , so that the amount of aerosol generated per unit time when the first nebulizer 31 is working is greater than the amount of aerosol generated per unit time when the second nebulizer 41 is working.

[0090] In some embodiments, reference may be made to Figure 4 and Figure 7 , there are two first heating elements 311 in the first atomizer 31, and three first power-taking electrodes 312; one of the first power-taking electrodes 312 is electrically connected to the two first heating elements 311 at the same time, and the other two first power-taking electrodes 312 are electrically connected to the two first heating elements 311 in a one-to-one correspondence. This allows the two first heating elements 311 to heat the aerosol-generating substrate separately or simultaneously. The two first heating elements 311 can use different electrical powers to heat the aerosol-generating substrate, or they can use the same aerosol-generating substrate to heat the aerosol-generating substrate. Based on this, N≥1, M=2, B=3, C=2, A≥3, and preferably the number A of power supply electrodes 11 is equal to 3.

[0091] In some embodiments, reference may be made to Figure 10, there are one or more second heating elements 411 in the second atomizer 41, and there are two second power-taking electrodes 412, that is, N≥1, C=2. The opposite ends of one or more second heating elements 411 are electrically connected to the two second power-taking electrodes 412 respectively. When there are multiple second heating elements 411, the multiple second heating elements 411 can only heat the aerosol-generating matrix at the same time. When there are multiple second heating elements 411, the multiple second heating elements 411 can be arranged in series or in parallel between the two second power-taking electrodes 412. In such a case Figure 10 In the illustrated embodiment, the second atomizer 41 has only one second heating element 411 , ie, N=1.

[0092] The adsorption element 214 in the first atomizer 31 is defined as the first adsorption element. In some embodiments, reference may be made to Figure 6 The M first heating elements 311 are staggered and arranged on the same first adsorption element, so as to increase the heating area of ​​the first atomizer 31 for heating the aerosol-generating substrate and increase the total contact area between the M first heating elements 311 and the first adsorption element, which helps to improve the aerosol generation efficiency.

[0093] In such Figure 6 In the illustrated embodiment, at least a portion of the first adsorption element is generally configured as a tubular body, with M first heating elements 311 disposed adjacent to the inner surface of the tubular body. The M first heating elements 311 may also be configured as tubular bodies, and the M first heating elements 311 may be sequentially arranged along the extension of the tubular body. The first adsorption element primarily adsorbs the aerosol-forming substrate from the storage chamber within the first atomizer 31 through its outer surface, then directs the aerosol-forming substrate to its inner surface for heating by the first heating element 311, generating an aerosol.

[0094] The adsorption element 214 in the second atomizer 41 is defined as a second adsorption element. When there are multiple second heating elements 411, the multiple second heating elements 411 are staggered and arranged on the same second adsorption element, so as to increase the heating area of ​​the second atomizer 41 for heating the aerosol-generating substrate and increase the total contact area between the multiple second heating elements 411 and the second adsorption element, which helps to improve the aerosol generation efficiency.

[0095] In some embodiments (not shown), the aerosol generating device includes both a first atomizer and a second atomizer. The first atomizer and the second atomizer can be electrically connected to the power supply assembly in a mutually exclusive manner by moving or rotating the first atomizer and the second atomizer relative to the power supply assembly, or by moving or rotating the power supply assembly.

[0096] In some embodiments, reference may be made to Figure 1, the first atomizer 31 and the second atomizer 41 are mutually exclusive in the aerosol generating device 100. In other words, when the aerosol generating device 100 has the first atomizer 31, the aerosol generating device 100 does not have the second atomizer 41; and when the aerosol generating device 100 has the second atomizer 41, the aerosol generating device 100 does not have the first atomizer 31. Based on this, the first atomizer 31 can be removably disposed in the aerosol generating device 100, so that after the first atomizer 31 is removed, the second atomizer 41 can be disposed in the aerosol generating device 100, and the second atomizer 41 occupies at least part of the space in the aerosol generating device 100 originally used to accommodate the first atomizer 31. And / or, the second atomizer can be removably disposed in the aerosol generating device, so that after the second atomizer 41 is removed, the first atomizer 31 can be disposed in the aerosol generating device 100, and the first atomizer 31 occupies at least part of the space in the aerosol generating device 100 originally used to accommodate the second atomizer 41.

[0097] In some embodiments, reference may be made to Figure 3-Figure 6 The first atomizing assembly 3 includes a plurality of first atomizers 31 , and the first atomizing assembly 3 is configured to be rotatable relative to the power supply assembly 1 so as to select at least one of the plurality of first atomizers 31 to be electrically connected to the power supply assembly 1 through rotation.

[0098] Therefore, when the aerosol-generating substrate in one of the first atomizers 31 is insufficient, the first atomizer assembly 3 can be rotated relative to the power supply assembly 1 to electrically connect the first atomizer 31 with more sufficient aerosol-generating substrate. Alternatively, when a different puff flavor is desired, the first atomizer assembly 3 can be rotated relative to the power supply assembly to switch the first atomizer 31 electrically connected to the power supply assembly 1.

[0099] Furthermore, the first atomizer assembly 3 also includes a first bracket 32, in which the plurality of first atomizers 31 are held. Specifically, the first bracket 32 ​​may include a plurality of first chambers 321 and a first partition 322 located between adjacent first chambers 321. The plurality of first atomizers 31 may be disposed in a one-to-one correspondence within the plurality of first chambers 321. The first bracket 32 ​​may also include a first base 323, which defines at least a portion of the boundaries of one or a pair of first chambers 321 and is used to support the first atomizers 31 within the first chambers 321. The first base 323 defines a through-hole 3231, into which a portion of the first atomizer 31 can be partially engaged, or at least a portion of the first power extraction electrode 312 of the first atomizer 31 can be exposed through the through-hole 3231. This allows the first power extraction electrode 312 to abut against the corresponding power supply electrode 11 when the first atomizer assembly 3 is rotated relative to the power supply assembly 1 to an appropriate position.

[0100] The first bracket 32 ​​may also include a lower docking column 324 connected to the first base 323 and extending back to the first base 323. The aerosol generating device 100 or the power supply component 1 includes a base 5, which can support the first atomization component 31, and a lower docking hole 51 is provided on the base 5. The lower docking column 324 is rotatably arranged in the lower docking hole 51, and the first atomization component 31 is configured to rotate around the central axis of the lower docking column 324 or the lower docking hole 51.

[0101] For further reference, Figure 11-12 The base 5 includes a flexible pad 52, a support plate 53 and a suction detector 54. A detection channel is also provided in the base, and the detection channel extends between the flexible pad 52 and the support plate 53. The power supply electrode 11 is fixed on the support plate 53, and the flexible pad 52 and the suction detector 54 are arranged on opposite sides of the support plate 53. A first through hole 521 is provided on the flexible pad 52, and a second through hole 531 and a third through hole 532 are provided on the support plate 53. The third through hole 532 fluidly connects the suction detector 54 and the detection channel. The second through hole 531 is provided upstream of the first through hole 521 and the detection channel to guide the external air to the first through hole 521 and the detection channel. The flexible pad 52 elastically abuts the atomizer 21 electrically connected to the power supply component 1, so that the first through hole 521 and the atomizer 21 electrically connected to the power supply component 1 are sealed.

[0102] The aerosol generating device 100 also includes an air inlet channel that fluidly connects the external air and the second through hole 531. The power supply assembly 1 also includes a power supply 12 and a circuit board 13. The power supply 12 can include any suitable battery. For example, the power supply 12 can include a lithium battery. Alternatively, the power supply 12 can include a rechargeable battery. Alternatively, the power supply 12 can include a disposable battery. The circuit board 13 is electrically connected to the power supply 12. A controller 131 on the circuit board 13 can control the power output of the power supply 12. The power supply electrode 11 is electrically connected to the circuit board 13.

[0103] When the atomizer 21 electrically connected to the power supply assembly 1 is inhaled, at least a portion of the air in the air inlet channel flows into the first through-hole 521 via the second through-hole 531. Simultaneously, the air in the third through-hole 532 flows into the first through-hole 521 via the detection channel. The air in the first through-hole 521 then flows into the atomizer 21, which is in sealed communication with the first through-hole 521. The puff detector 54 can detect the airflow or pressure in the third through-hole 532 and / or the detection channel. When the airflow or pressure in the third through-hole 532 and / or the detection channel reaches a threshold, or when the change in airflow or pressure reaches a threshold, the puff detector 54 determines that the atomizer 21, which is in sealed communication with the first through-hole 521, has been inhaled. Upon detecting a puff, the puff detector 54 can generate a puff signal. Based on this puff signal, the controller 131 can control the power supply 12 to provide electrical power to a corresponding one of the A power supply electrodes 11, thereby causing the atomizer 21 electrically connected to the power supply assembly 1 to generate aerosol.

[0104] When the atomizer 21 electrically connected to the power supply assembly 1 is not being inhaled, at least part of the air in the air inlet channel flows into the detection channel through the second through hole 531, and then flows to the suction detector 54 through the third through hole 532, thereby restoring the airflow or air pressure in the third through hole 532 and / or the detection channel to balance with the external air pressure.

[0105] The base 5 is used to support the atomizer assembly 2 in the longitudinal direction, and the detection channel extends laterally, so that the first through hole 521 and the third through hole 532 are staggered in the transverse direction, so as to prevent the air flow glue or condensation formed by the aerosol flowing back from the first through hole 521 from flowing into the third through hole 532, thereby preventing the aerosol and / or condensation from flowing to the puff detector 54, which helps the puff detector 54 maintain good sensitivity during long-term use.

[0106] In some embodiments, the front side of the flexible pad 52 is disposed toward the atomizing assembly 2, and the back side of the flexible pad 42 is disposed toward the supporting plate 53. Figure 8In the illustrated embodiment, the back of the flexible pad 52 has a guide groove 522. One end of the guide groove 522 is connected to the first through-hole 521, and the other end corresponds to the third through-hole 532 on the support plate 53. Airflow can flow along the guide groove 522 between the first through-hole 521 and the third through-hole 532. The guide groove 522 can partially define the boundaries of the detection channel, while the support plate 53 can define the remaining boundaries of the detection channel.

[0107] Preferably, the guide groove 522 extends non-linearly to increase the length of the airflow path between the first through hole 521 and the third through hole 532 , thereby preventing condensation formed by airflow glue or aerosol from flowing into the third through hole 532 .

[0108] Preferably, a condensation zone 523 is further provided on the back side of the flexible pad 52. The guide groove 522 passes through the condensation zone 523, and the width of the condensation zone 523 is greater than the width of the guide groove 522. The velocity of the reflowing aerosol is reduced as it flows along the guide groove 522 into the condensation zone 523, thereby helping the aerosol to more fully condense in the condensation zone 523 to form condensate, rather than continuing to flow in a gaseous state along the guide groove 522 and into the third through hole 532. The condensate formed by the aerosol in the condensation zone 523 and at least a portion of the condensate that flows back from the first through hole 521 and flows along the guide groove 522 into the condensation zone 523 can be retained in the condensation zone 523, thereby preventing the condensate from flowing along the guide groove 522 into the third through hole 532.

[0109] like Figure 8 In the illustrated embodiment, the flexible pad 52 is further provided with A retaining holes 524. The A power supply electrodes 11 are provided in a one-to-one correspondence with the A retaining holes 524, and at least a portion of the power supply electrode 11 is positioned with interference fit within the corresponding retaining hole 524. This creates a seal between the flexible pad 52 and the power supply electrode 11, preventing backflowing aerosol and condensed liquid formed by the aerosol from leaking along the sidewalls of the power supply electrode 11. The end of the power supply electrode 11 can protrude from the flexible pad 52, thereby being positioned within the accommodating cavity 61.

[0110] In some embodiments, reference may be made to Figure 2 and Figure 3 The base 5 is further provided with a first prompting mechanism 55, and the first bracket 32 ​​is provided with a second prompting mechanism 325. When the first prompting mechanism 55 and the second prompting mechanism 325 correspond to each other, the aerosol generating device 100 generates a sensory signal such as vibration or sound. Based on this sensory signal, the user can determine whether one or more first atomizers 31 in the first atomizing assembly 3 are electrically connected to the power supply assembly 1.

[0111] Furthermore, the first prompt mechanism 55 includes a bead, and the second prompt mechanism 325 includes a groove. When the first prompt mechanism 55 corresponds to the second prompt mechanism 325, a portion of the bead is embedded in the groove.

[0112] In some embodiments, reference may be made to Figure 2 and Figure 11 The aerosol generating device 100 further includes a housing 6 having an internal accommodating cavity 61. At least a portion of the power supply electrode 11 is exposed in the accommodating cavity 61. The first atomizer assembly 3 is configured to be removably disposed in the accommodating cavity 61. Therefore, the first atomizer assembly 3 can be removed from the accommodating cavity 61 as a whole, and then the second atomizer assembly 4 or a new first atomizer assembly 3 can be assembled into the accommodating cavity 61.

[0113] The base 5 or the flexible pad 52 may define a portion of the boundary of the accommodating cavity 61 . The bead may be exposed in the accommodating cavity 61 .

[0114] In some embodiments, reference may be made to Figure 1 and Figure 11 The aerosol generating device 100 further includes a mouthpiece assembly 7, which is connected to the housing 6 or is a component of the housing 6. The multiple first atomizers 31 in the first atomizer assembly 3 cannot all be in fluid communication with the air inlet 71 of the mouthpiece assembly 7 at the same time. Only some of the multiple first atomizers 31 in the first atomizer assembly 3 can be in fluid communication with the air inlet 71 of the mouthpiece assembly 7.

[0115] The first atomizer assembly 31 is configured to be rotatable relative to the nozzle assembly 7 so as to select at least one of the plurality of first atomizers 31 to be in fluid communication with the air inlet 71 of the nozzle assembly 7 through the rotation.

[0116] For example, the first atomizer assembly 3 is rotatably disposed in the accommodating chamber 61, so that the first atomizer assembly 3 can rotate relative to the housing 6. The mouthpiece assembly 7 and the power supply assembly 1 can remain relatively stationary relative to the housing 6. Thus, only the first atomizer assembly 3 can be driven to rotate within the accommodating chamber 61, thereby rotating the first atomizer assembly 3 relative to the power supply assembly 1 and the mouthpiece assembly simultaneously. This allows the first atomizer 311, which is electrically connected to the power supply assembly 1, to simultaneously be in fluid communication with the air inlet 71 of the mouthpiece assembly 7.

[0117] For further information, please refer to Figure 1 and Figure 2 A window corresponding to the accommodating cavity 61 is provided on the side wall of the shell 6, and a portion of the first atomizing assembly 31 can be exposed through the window for the user to operate to drive the first atomizing assembly 31 to rotate.

[0118] In such Figure 5 and Figure 11 In the illustrated embodiment, the first bracket 32 ​​may further include an upper docking post 326 connected to the first partition plate 322 and extending toward the nozzle assembly 7. The nozzle assembly 7 includes an upper docking hole 72. The upper docking post 326 is rotatably disposed in the upper docking hole 72. The first atomizer assembly 3 is configured to rotate about the central axis of the upper docking post 326 or the upper docking hole 72. The upper docking post 326 and the lower docking post 324 may be disposed along a common central axis.

[0119] Or for example, the nozzle assembly 7 is rotatably connected to the housing 6, and the power supply assembly 1 can rotate relative to the housing 6. The first atomizer assembly 3 is non-rotatable in the accommodating cavity 61, so that the first atomizer assembly 3 and the housing 6 can remain relatively stationary.

[0120] The power supply assembly 1 and the suction nozzle assembly 7 can be driven to rotate relative to the first atomizer assembly 3, so that one or more first atomizers 31 in the first atomizer assembly 3 are electrically connected to the power supply assembly 1 and fluidically connected to the air inlet 71 of the suction nozzle assembly 7.

[0121] Alternatively, the power supply assembly 1 and the suction nozzle assembly 7 may be driven simultaneously to rotate relative to the first atomizer assembly 3 , so that the first atomizer 31 electrically connected to the power supply assembly 1 can be in fluid communication with the air inlet 71 of the suction nozzle assembly 7 at the same time.

[0122] Alternatively, in some embodiments, the first atomizer assembly 3 includes a nozzle assembly 7. The nozzle assembly 7 is rotatably connected to the first bracket 32, so that the nozzle assembly 7 can be rotated relative to the first bracket 32 ​​to change the first atomizer 31 in fluid communication with the air inlet 71 of the nozzle assembly 7. Alternatively, the nozzle assembly 7 is a component of the first bracket 32, so that the air inlet 71 of the nozzle assembly 7 can be simultaneously in fluid communication with multiple first atomizers 31 in the first atomizer assembly 3.

[0123] Alternatively, in some embodiments, the aerosol generating device 100 further includes a mouthpiece assembly 7, which is connected to the housing 6 or is a component of the housing 6. The multiple first atomizers 31 in the first atomizing assembly 3 can all be in fluid communication with the inlet 71 of the mouthpiece assembly 7 at the same time.

[0124] In some embodiments, reference may be made to Figure 8 and Figure 9 The second atomizer assembly 4 includes multiple second atomizers 41. The second atomizer assembly 4 is configured to replace the first atomizer assembly 3 and be arranged in the accommodating cavity 61. It can rotate relative to the power supply assembly 1 so as to select at least one of the multiple second atomizers 41 to be electrically connected to the power supply assembly 1 through rotation.

[0125] In this embodiment, the accommodating cavity 61 can accommodate either the first atomizing assembly 3 or the second atomizing assembly 4 , but cannot accommodate both the first atomizing assembly 3 and the second atomizing assembly 4 at the same time.

[0126] In this embodiment, the second atomization assembly 4 can be removably disposed in the accommodating cavity 61 , so that the second atomization assembly 4 can be taken out from the accommodating cavity 61 .

[0127] The second atomizer assembly 4 also includes a second bracket 42, and a plurality of second atomizers 41 are retained in the second bracket 42. Specifically, the second bracket 42 may have a plurality of second chambers and a second partition plate located between two adjacent second chambers, and the plurality of second atomizers 41 may be arranged in a one-to-one correspondence in the plurality of second chambers. The second bracket 42 may also include a second base 421, which defines at least a portion of the boundary of one or a pair of second chambers, and the second base 421 is used to support the second atomizer 41 located in the second chamber. A through hole is provided on the second base 421, and a portion of the second atomizer 41 can be embedded in the corresponding through hole, or at least a portion of the second power electrode 412 of the second atomizer 41 can be exposed through the through hole, so that when the second atomizer assembly 4 is rotated to an appropriate position relative to the power supply assembly 1, the second power electrode 412 can be in contact with the corresponding power supply electrode 1.

[0128] The second bracket 42 can be rotatably connected to the base 5. The second bracket 42 can be rotatably connected to the nozzle assembly 7.

[0129] In some embodiments, reference may be made to Figure 8 The second bracket 42 is provided with a third prompting mechanism 422. When the second prompting mechanism 55 corresponds to the third prompting mechanism 422, the aerosol generating device 100 generates a sensory signal such as vibration or sound. Based on this sensory signal, the user can determine whether one or more second atomizers 41 in the second atomizing assembly 4 are electrically connected to the power supply assembly 1.

[0130] For further information, please refer to Figure 8 The third prompting mechanism 422 includes a groove. When the second prompting mechanism 55 corresponds to the third prompting mechanism 422, a portion of the bead of the second prompting mechanism 55 can be embedded in the groove.

[0131] In some embodiments, reference may be made to Figure 1 and Figure 2The aerosol generating device further includes a mouthpiece assembly 7, which is connected to the housing 6 or is an integral part of the housing 6. The multiple second atomizers 41 in the second atomizer assembly 4 cannot all be in fluid communication with the air inlet 71 of the mouthpiece assembly 7 at the same time. Only some of the multiple second atomizers 41 in the second atomizer assembly 4 can be in fluid communication with the air inlet 71 of the mouthpiece assembly 7.

[0132] The second atomizer assembly 4 is configured to be rotatable relative to the nozzle assembly 7 so as to select at least one of the plurality of second atomizers 41 to be in fluid communication with the air inlet 71 of the nozzle assembly 7 through the rotation.

[0133] In some embodiments, reference may be made to Figure 5 and Figure 9 The number of the first atomizers 31 in the first atomization assembly 3 is less than the number of the second atomizers 41 in the second atomization assembly 4. However, this is not limited thereto.

[0134] In some embodiments, reference may be made to Figure 2 The multiple power supply electrodes 11 are arranged in a non-linear manner. Preferably, the arrangement trajectory of the multiple power supply electrodes 11 at least partially coincides with the trajectory of the atomizer assembly 2 rotating relative to the power supply assembly 1.

[0135] In some embodiments, reference may be made to Figure 11 and Figure 14 The aerosol generating device further includes an air regulating switch 8, which is configured to adjust the air intake volume of the air intake channel. The second through hole 531 may be a component of the air intake channel.

[0136] The gas regulating switch 8 may include a base 81 and a plurality of air inlet holes 82 provided on the base 81. Figure 14 In the embodiment shown, there are three air inlet holes 82. Different air inlet holes 82 have different air inlet areas, so under the same suction force, the amount of air entering the second through hole 531 through different air inlet holes 82 is different.

[0137] The air regulating switch 8 is configured to be rotatable relative to the second through hole 531, so as to change the air inlet 82 correspondingly connected to the second through hole 531. Preferably, the plurality of air inlet holes 82 are in fluid communication with the second through hole 531 in a mutually exclusive manner.

[0138] The housing 6 may include a bottom cover 62, and the gas regulating switch 8 may be arranged on the bottom cover 62 and may rotate relative to the bottom cover 62. An arcuate through groove 621 may be provided on the bottom cover 62, and the gas regulating switch 8 also includes a protrusion 83, which is located in the arcuate through groove 621 and may rotate along the arcuate through groove 621, so that the rotation angle of the gas regulating switch 8 is limited by the extension length of the arcuate through groove 621. The protrusion 83 is configured to be operated by a user to drive the gas regulating switch 8 to rotate relative to the bottom cover 62. Figure 11 In the illustrated embodiment, one of the air inlet holes 82 passes through the protrusion 83 . Preferably, the air inlet hole 82 passing through the protrusion 83 is the air inlet hole 82 at the middle position among the multiple air inlet holes 82 on the regulating switch 8 .

[0139] In some embodiments, reference may be made to Figure 14 The inner side of the bottom cover 62 is also provided with an annular rib 622 and a first shift mechanism 623 disposed on the annular rib 622. The base 81 of the gas regulating switch 8 is rotatably disposed around the annular rib 622, and a second shift mechanism 84 is disposed on the base 81. The number of at least one of the first shift mechanisms 623 and the second shift mechanism 84 is equal to the number of air inlet holes 82. When the first shift mechanism 623 and the second shift mechanism 84 correspond to each other, the aerosol generating device 100 generates a sensory signal such as vibration or sound. Based on this sensory signal, the user can determine whether one or more of the multiple air inlet holes 82 are connected to the second through hole 531.

[0140] For further information, please refer to Figure 14 The first gear mechanism 623 includes an arched portion, and the second gear mechanism 84 includes a groove. When the first gear mechanism 623 corresponds to the second gear mechanism 84, a portion of the arched portion is embedded in the groove.

[0141] It can be seen from the above embodiments that the number of the first power extraction electrodes 312 of the first atomizer 31 and the number of the second power extraction electrodes 412 of the second atomizer 41 are different, but the first atomizer 31 and the second atomizer 41 can be electrically connected to the power supply component 1 mutually exclusively, so the power supply component 1 is compatible with the first atomizer 31 and the second atomizer 41, or is compatible with the first atomizer component 3 including the first atomizer 31 and the second atomizer component 4 including the second atomizer 41.

[0142] Based on this, in some embodiments of the present application, the power supply component 1 can identify the first atomizer 31 and the second atomizer 41, and then the controller 131 can control the distribution of the output electric power of the power supply 12 on the corresponding power supply electrode 11 to adapt to the first atomizer 31 or the second atomizer 41 electrically connected thereto and provide electric power thereto.

[0143] In some embodiments of the present application, when the first atomizer 31 is electrically connected to the power supply assembly 1, the power supply 12 can provide electrical power to all power supply electrodes 11 that are in contact with the B first power supply electrodes 312 of the first atomizer 31, and the idle power supply electrodes 11 in the power supply assembly 1 that are not in contact with the first power supply electrode 312 of the first atomizer 31 can be configured to be unable to obtain the electrical power provided by the power supply 12.

[0144] When the second atomizer 41 is electrically connected to the power supply component 1, the power supply 12 can provide electrical power to all power supply electrodes 11 that are in contact with the C second power supply electrodes 412 of the second atomizer 41. The idle power supply electrodes 412 in the power supply component 1 that are not in contact with the second power supply electrodes 412 of the second atomizer 41 can be configured to be unable to obtain the electrical power provided by the power supply 12.

[0145] The number of power supply electrodes 11 in the power supply assembly 1 that obtain power when electrically connected to the first atomizer 31 may be greater than the number of power supply electrodes 11 in the power supply assembly 1 that obtain power when electrically connected to the second atomizer 41. Alternatively, the number of idle power supply electrodes 11 in the power supply assembly 1 when electrically connected to the first atomizer 31 may be less than the number of idle power supply electrodes 11 in the power supply assembly 1 when electrically connected to the second atomizer 41.

[0146] In some embodiments, reference may be made to Figure 15 In the power supply component 1, some of the A power supply electrodes 11 are first electrodes 111, and the remaining power supply electrodes are second electrodes 112. The controller 131 is electrically connected to at least some of the A power supply electrodes 11, so that the controller 131 can obtain electrical parameters between at least some of the first electrodes 111 and the second electrodes 112 in the same circuit as the first electrode 111. The controller 131 is electrically connected to the power supply 12 and can control the power supply 12 to output electrical power to the circuit whose electrical parameters meet the threshold.

[0147] When the first atomizer 31 is electrically connected to the power supply assembly 1, X circuits can be formed between the first atomizer 31 and the power supply 12, each of which includes a first electrode 111 and a second electrode 112. When the second atomizer 41 is electrically connected to the power supply assembly 1, Y circuits can be formed between the second atomizer 41 and the power supply 12, each of which includes a first electrode 111 and a second electrode 112. This allows the controller 131 to obtain the electrical parameters and associate them with the atomizer 21 electrically connected to the power supply assembly 1. Here, X and Y are both integers, and 1≤Y<X.

[0148] In some embodiments, the first atomizer 31 includes a first identity chip carrying first identity information. When the first atomizer 31 is electrically connected to the power supply assembly 1, the first identity chip forms a circuit with the power supply 12 via a first electrode 111 and a second electrode 112. The electrical parameters acquired by the controller 131 can therefore be associated with the first identity information, and the controller 131 can identify the identity of the first atomizer 31 based on the electrical parameters.

[0149] Similarly, the second atomizer 41 includes a second identity chip carrying second identity information. When the second atomizer 41 is electrically connected to the power supply assembly 1, the second identity chip forms a circuit with the power supply 12 via a first electrode 111 and a second electrode 112. The electrical parameters acquired by the controller 131 can therefore be associated with the second identity information, and the controller 131 can identify the identity of the second atomizer 41 based on these electrical parameters. Because the first identity information is different from the second identity information, the controller 131 can distinguish between the first atomizer 31 and the second atomizer 41 based on the acquired electrical parameters.

[0150] In some embodiments, since each circuit between the atomizer 21 and the power supply 12 includes a first electrode 111 and a second electrode 112, the controller 131 can be configured to obtain the electrical parameters in each circuit formed between the atomizer 21 and the power supply 12. When the number of electrical parameters obtained by the controller 131 is X, the controller 131 can determine that the atomizer 21 electrically connected to the power supply assembly 1 is the first atomizer 31. When the number of electrical parameters obtained by the controller 131 is Y, the controller 131 can determine that the atomizer 21 electrically connected to the power supply assembly 1 is the second atomizer 41.

[0151] Specifically, when the first atomizer 31 is electrically connected to the power supply assembly 1, the controller 131 can obtain X electrical parameters based on the X circuits between the first atomizer 31 and the power supply 12. These X electrical parameters can correspond one-to-one with the X circuits. When the second atomizer 41 is electrically connected to the power supply assembly 1, the controller 131 can obtain Y electrical parameters based on the Y circuits between the second atomizer 41 and the power supply 12. These Y electrical parameters can correspond one-to-one with the Y circuits. The controller 131 can distinguish between the first atomizer 31 and the second atomizer 41 by identifying the number of electrical parameters it obtains.

[0152] Furthermore, the first atomizer 31 has M first heating elements 311. When the first atomizer 31 is electrically connected to the power supply assembly 1, an independent circuit is formed between each first heating element 311 and the power supply 12. In other words, M circuits can be formed between the M first heating elements 311 and the power supply 12.

[0153] Here, M may be smaller than X, or M may be equal to X. When X=M, each loop formed between the first atomizer 31 and the power source 12 includes a first heating element 311 .

[0154] And / or, the second atomizer 41 has N second heating elements 411. When the second atomizer 41 is electrically connected to the power supply assembly 1, an independent circuit is formed between each second heating element 411 and the power supply 12. In other words, N circuits can be formed between the N second heating elements 411 and the power supply 12.

[0155] N may be smaller than Y, or N may be equal to Y. When Y=N, each loop formed between the second atomizer 41 and the power source 12 includes a second heating element 411 .

[0156] In some embodiments, the first atomizer 31 includes B first power-collecting electrodes 312 , and the B first power-collecting electrodes 312 are electrically connected to M first heating elements 311 , so that when the first atomizer 31 is electrically connected to the power supply component 1 , the M first heating elements 311 can generate heat.

[0157] When the first atomizer 31 is electrically connected to the power supply assembly 1, some of the B first power-collecting electrodes 312 abut against the first electrode 111, and some abut against the second electrode 112. In the power supply assembly 1, among the B power supply electrodes 11 abutting against the first power-collecting electrode 312 in the first atomizer 31, each first electrode 111 can be electrically connected to a first heating element 311. As a result, among the B power supply electrodes 11 abutting against the first power-collecting electrode 311 in the first atomizer 31, there are M first electrodes 111 and BM second electrodes 112.

[0158] Among the B power supply electrodes 11 in the power supply assembly 1 that abut the first power extraction electrode 312 in the first atomizer 31, there can be only one second electrode 112, which is electrically connected to M first heating elements 311. In other words, BM = 1. M can be greater than 1, meaning there can be multiple first electrodes 111.

[0159] In some embodiments, the second atomizer 41 includes C second power electrodes 412 , which are electrically connected to N second heating elements 411 , so that when the second atomizer 41 is electrically connected to the power supply assembly 1 , the N second heating elements 411 can generate heat.

[0160] When the second atomizer 41 is electrically connected to the power supply assembly 1, some of the C second power-collecting electrodes 412 abut against the first electrode 111, and some abut against the second electrode 112. In the C power supply electrodes 11 in the power supply assembly 1 that abut against the second power-collecting electrode 412 in the second atomizer 41, each first electrode 111 can be electrically connected to a second heating element 412. As a result, in the C power supply electrodes 11 in the power supply assembly 1 that abut against the second power-collecting electrode 412 in the second atomizer 41, there are N first electrodes 111 and CN second electrodes 112.

[0161] Of the C power supply electrodes 11 in the power supply assembly 1 that abut the second power extraction electrode 412 in the second atomizer 41, there can be only one second electrode 112, which is electrically connected to N second heating elements 411. In other words, CN = 1. N can be greater than 1, meaning there can be multiple first electrodes 111.

[0162] One of the first electrode 111 and the second electrode 112 is used to be electrically connected to the positive electrode of the power source 12, and the other is used to be electrically connected to the negative electrode of the power source 12. In some embodiments of the present application, the first electrode 111 is used to be electrically connected to the positive electrode of the power source 12, and the second electrode 112 is used to be electrically connected to the negative electrode of the power source 12.

[0163] Furthermore, the controller 131 is electrically connected to the first electrode 111 to collect first electrical data. The electrical parameters between the first electrode 111 and the second electrode 112 in the same loop as the first electrode 111 include the first electrical data, or are associated with the first electrical data. The first electrical data may include voltage data at the first electrode 111, current data flowing through the first electrode 111, and / or the resistance value between the first electrode 111 and the corresponding second electrode 112. In some examples, when the first electrical data on a certain loop meets a threshold value, the controller 131 may control the power supply 12 to output electrical power to the loop or to the first electrode 111 on the loop. This enables the corresponding heating element 215 to generate heat.

[0164] In some embodiments, the power supply assembly 1 further includes sampling circuits 14, which are electrically connected one-to-one between the first electrode 111 and the positive electrode of the power supply 12, so that the sampling circuits 14 and the first electrodes 111 can be in the same circuit. The number of sampling circuits 14 is equal to the number of first electrodes 111. The controller 131 can collect the voltage of the sampling circuit 14 and / or the current flowing through the sampling circuit 14 based on the sampling circuit 14, and then combine the voltage and / or current with the first electrical data to obtain relevant electrical parameters through calculation.

[0165] As an example, the electrical parameters between the first electrode 111 corresponding to the sampling line 14 and the second electrode 112 in the same loop as the first electrode 111 include the resistance value Rx between the first electrode 111 corresponding to the sampling line 14 and the second electrode 112 in the same loop as the first electrode 111, Rx = (U1*R0) / (U-U1); wherein R0 is the resistance value of the sampling line 14; the first electrical data includes voltage data U1, which can be roughly the voltage between the first electrode 111 and the negative pole of the power supply; and U is the output voltage of the power supply 12.

[0166] As an example, the controller 131 is electrically connected to the second electrode 112 to collect second electrical data. The electrical parameters between the first electrode 111 corresponding to the sampling line 14 and the second electrode 112 in the same loop as the first electrode 111 include the resistance value Rx between the first electrode 111 corresponding to the sampling line 14 and the second electrode 112 in the same loop as the first electrode 111, where Rx = (ΔU*R0) / (U-ΔU). Where R0 is the resistance value of the sampling line 14; U is the output voltage of the power supply 12; ΔU = U2-U1. The first electrical data includes voltage data U1, and the second electrical data includes voltage data U2. ΔU is the voltage between the first electrode and the second electrode in the same loop. In some examples, ΔU is the total voltage value of one or more heating elements 215 connected between the first electrode 111 and the second electrode 112. The voltage data U2 can be approximately the voltage between the second electrode 112 and the negative terminal of the power supply 12.

[0167] As an example, a node between the sampling line 14 and the positive electrode of the power supply 12 is electrically connected to the controller 131 , so that the controller 131 can collect the third electrical data.

[0168] The electrical parameters between the first electrode 111 corresponding to the sampling line 14 and the second electrode 112 in the same circuit as the first electrode 111 include a resistance value Rx between the first electrode 111 corresponding to the sampling line 14 and the second electrode 112 in the same circuit as the first electrode 111, where Rx = R0*(U-ΔU′) / ΔU′; wherein R0 is the resistance value of the sampling line 14; U is the output voltage of the power supply 12; ΔU′ = U3-U1, the first electrical data includes voltage data U1, and the third electrical data includes voltage data U3. ΔU′ is the voltage between opposite ends of the sampling line 14. The voltage data U3 can be approximately the voltage between the node between the sampling line 14 and the positive electrode of the power supply 12 and the negative electrode of the power supply 12.

[0169] As an example, when the resistance value Rx satisfies: 0.5Ω≤Rx≤3Ω, the electrical parameter meets the threshold value. The controller 131 can control the power supply 12 to output electrical power to the relevant circuit or to the relevant first electrode 111, thereby enabling the corresponding heating element 215 to generate heat.

[0170] In some embodiments, reference may be made to Figure 15 The power supply component 1 also includes a power supply circuit 15, which is connected in parallel with the sampling circuit 14 in a one-to-one correspondence; a switching element Q is provided on both the power supply circuit 15 and the sampling circuit 14, and the controller 131 is electrically connected to the switching element Q to control the switching element Q to be turned on or off.

[0171] When the atomizer 21 is electrically connected to the power supply assembly 1, the controller 131 can control the switch element Q on the sampling circuit 14 to be turned on and the switch element Q on the power supply circuit 15 to be turned off, so as to collect corresponding electrical data and / or electrical parameters, thereby identifying the atomizer 21 electrically connected to the power supply assembly 1. The controller 131 can then control the switch element Q on the sampling circuit 14 to be turned off and the switch element Q on the power supply circuit 15 to be turned on, so that the power supply 12 outputs electrical power to the corresponding first electrode 11 through the power supply circuit 15, thereby generating a voltage to the atomizer 21 electrically connected to the power supply assembly 1, thereby generating an aerosol.

[0172] Preferably, the total resistance value of the power supply line 15 is smaller than the total resistance value of the sampling line 14. The total resistance value of the sampling line 14 may be between 1.6Ω and 10Ω.

[0173] In some embodiments, reference may be made to Figure 15 The power supply component 1 also includes a connection identification circuit 16, which is arranged in a one-to-one correspondence with the first electrode 111, so that when the first electrode 111 abuts the power-taking electrode, the electronically controlled sensory prompter in the aerosol generating device 100 is triggered to generate a sensory prompt signal. For example, when the first electrode 111 abuts the power-taking electrode, the display screen or LED on the aerosol generating device 100 will be lit.

[0174] When the first atomizer assembly 3 or the second atomizer assembly 4 rotates relative to the power supply assembly 1 , when the electronically controlled sensory indicator generates a prompt signal, it indicates that one of the atomizers 21 is electrically connected to the power supply assembly 1 .

[0175] More specifically, in Figure 2 and Figure 3 In the embodiment shown, part of the second prompt mechanism 325 is disposed between two adjacent first atomizers 31. During the relative rotation of the first atomizer assembly 3 and the power supply assembly 1:

[0176] When the first prompt mechanism 55 on the base 5 corresponds to the second prompt mechanism 325 between two adjacent first atomizers 31, although mechanical vibration and / or mechanical sound are generated, the power supply assembly 1 is not electrically connected to any of the first atomizers 31 in the first atomizer assembly 3. At the same time, because the first electrode 111 is not in contact with the power extraction electrode, the electronically controlled sensory prompter such as the display screen or LED on the aerosol generating device 100 cannot generate a prompt signal to prompt that the first atomizer 31 in the first atomizer assembly 3 is electrically connected to the power supply assembly 1.

[0177] If the first prompt mechanism 55 on the base 5 corresponds to the second prompt mechanism 325 associated with the first atomizer 31, not only mechanical vibration and / or mechanical sound will be generated, but also because the first electrode 111 is in contact with the power-taking electrode, the display screen or LED or other electrically controlled sensory prompter on the aerosol generating device 100 can generate a prompt signal to prompt that the first atomizer 31 in the first atomizing assembly 3 is electrically connected to the power supply assembly 1.

[0178] Similarly, in Figure 2 and Figure 8 In the embodiment shown, part of the third prompting mechanism 422 is disposed between two adjacent second atomizers 41. During the relative rotation of the second atomizer assembly 4 and the power supply assembly 1:

[0179] When the first prompt mechanism 55 on the base 5 corresponds to the third prompt mechanism 422 between two adjacent second atomizers 41, although mechanical vibration and / or sound are generated, the power supply assembly 1 is not electrically connected to any of the second atomizers 41 in the second atomizer assembly 4. At the same time, because the first electrode 111 is not in contact with the power extraction electrode, the electronically controlled sensory prompter such as the display screen or LED on the aerosol generating device 100 cannot generate a prompt signal to prompt that the second atomizer 41 in the first atomizer assembly 4 is electrically connected to the power supply assembly 1.

[0180] If the first prompt mechanism 55 on the base 5 corresponds to the third prompt mechanism 422 associated with the second atomizer 41, not only mechanical vibration and / or mechanical sound will be generated, but also because the first electrode 111 is in contact with the power-taking electrode, the display screen or LED or other electrically controlled sensory prompter on the aerosol generating device 100 can generate a prompt signal to prompt that the second atomizer 41 in the second atomizing assembly 4 is electrically connected to the power supply assembly 1.

[0181] The connection identification circuit 16 can be set outside the controller 131 and connected in parallel with the power supply circuit 15 in a one-to-one correspondence, so that when the switching element Q on the power supply circuit 15 is turned on, the corresponding connection identification circuit 16 is short-circuited, and the electronically controlled sensory prompter can immediately stop generating the prompt signal.

[0182] The connection identification circuit 16 may be a component of an internal circuit of the controller 131 .

[0183] The connection identification line 16 has a relatively large resistance, and its resistance value may be greater than 1000Ω, for example, its resistance value may be approximately 1 MΩ.

[0184] In some embodiments, the number of heating elements 215 in the first atomizer 31 is greater than the number of heating elements 215 in the second atomizer 41, and each heating element 215 is capable of operating with approximately the same electrical power. This ensures that the electrical power output by the power supply 13 when the power supply assembly 1 is electrically connected to the first atomizer 31 is greater than the electrical power output by the power supply 12 when the power supply assembly 1 is electrically connected to the second atomizer 41. Furthermore, / or, the electrical power obtained by the first atomizer 31 when the power supply assembly 1 is electrically connected to the first atomizer 31 is greater than the electrical power obtained by the second atomizer 41 when the power supply assembly 1 is electrically connected to the second atomizer 41.
