Description

Technical Field

[0002] An aerosol generating device is a device that can atomize a liquid preparation to form an aerosol. However, in some exemplary prior arts, the aerosol generating device has multiple atomizers for storing liquid preparations, and the multiple atomizers can provide aerosols to users in turn. However, if the user does not switch the atomizer in time during use, the atomizer in the working position may dry burn due to too low liquid matrix content. If the atomizer is switched too early, the liquid matrix in the atomizer may not be fully utilized and wasted. Summary of the invention

[0003] The embodiment of the present application provides an aerosol generating device, which can identify the usage parameters of the nebulizer, so that the usage of the nebulizer can be identified.

[0009] In one example, the control circuit is further configured to stop the power supply component from providing power to the atomizer, or provide an indication, when the usage parameter of the atomizer is lower than a threshold value or exceeds a preset threshold range.

[0010] In one example, the identity information includes an impedance of the identity circuit, and different identity circuits have different impedances.

[0011] In one example, the aerosol generating device further includes a sensory prompter configured to generate a sensory prompt signal when a usage parameter of the nebulizer reaches a threshold value.

[0012] In one example, the usage parameter includes the accumulated or remaining usage time of the atomizer;

[0013] Alternatively, the usage parameter includes the accumulated or remaining number of puffs of the nebulizer.

[0014] In one example, the identity circuit is disposed on the power supply component.

[0015] In one example, the identity circuit is disposed on the atomizer assembly.

[0016] In one example, the power supply component includes a power supply and a circuit board, the circuit board has a power supply module, and the power supply component is configured to output power to the atomizer through the power supply module.

[0017] In one example, the identity circuit is arranged on the atomizer assembly, the number of the power supply modules is less than the number of the atomizers, and the circuit board is configured to be rotatable relative to the atomizer assembly.

[0018] In one example, there are multiple power supply modules, and each of the atomizers is electrically connected to a different power supply module;

[0019] The aerosol generating device further comprises a conductive member, which is configured to be driven to simultaneously change position relative to the circuit board and the atomizing assembly so as to selectively connect to one of the plurality of power supply modules.

[0020] In one example, the conductive component is configured to establish a conductive path between the power supply module selectively connected thereto and the corresponding atomizer, so that the atomizer is in a standby state or a working state.

[0021] In one example, the power supply module includes a first electrode group and a second electrode group associated with each other, the power supply module outputs power through the first electrode group, and the conductive member is configured to abut the power supply module having the second electrode group by abutting the second electrode group;

[0022] When the conductive member abuts against the power supply module, at least two electrodes in the second electrode group in the power supply module are connected to each other.

[0023] In one example, the recognition circuit and the identity circuit are both disposed on the circuit board.

[0024] In one example, the circuit board has an anode terminal and a cathode terminal, a plurality of the power supply modules are connected in parallel between the anode terminal and the cathode terminal, and the power supply is configured to provide power to the circuit board through the anode terminal and the cathode terminal.

[0028] The controller is configured to obtain a second electrical parameter of the detection resistor, and determine whether an abnormality occurs in the second circuit based on the second electrical parameter;

[0029] The controller is further configured to control at most one of the first switch and the second switch to be turned on, and to control the first switch to be turned on when it is determined that the second line is normal.

[0030] In one example, a plurality of the atomizers are connected to a common cathode, and the controller is configured to control the second switch to be turned on when the identity information of the identity circuit is identified, and control the first switch to be turned on after the identity information of the identity circuit is identified.

[0031] In the above-mentioned aerosol generating device, multiple atomizers respectively have identity circuits corresponding to them, and different identity circuits carry different identity information. The control circuit can identify different atomizers by identifying the identity information, and then can obtain the usage parameters of the corresponding atomizer, so that the usage of the atomizer can be identified, which helps the user to make a correct judgment on whether to switch the atomizer.

[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or suggesting the quantity or order of the indicated technical features relative to importance or implicitly indicating. 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 between the components under a certain specific posture (as shown in the accompanying drawings), and 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 comprising 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.

[0060] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0061] 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 a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be one or more central elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0062] Please refer to Figure 1-11 , an embodiment of the present application provides an aerosol generating device, the aerosol generating device includes a conductive member 1, a power supply component 3 and an atomizing component 2 having a plurality of atomizers 21. The conductive member 1 can be driven so that the conductive member 1 can change its position, so that the conductive member 1 can be used to select an atomizer 21 electrically connected to the power supply component 3, so that the power supply component 3 can provide power to the atomizer 21 selected by the conductive member 1, so that the selected atomizer 21 can generate an aerosol. It should be noted that the "electrical connection" and "electrical conduction" described in the present application are two different concepts. "Electrical connection" means that the conductive line between the two elements is connected, and there is a premise that current flows from one element to another. "Electrical conduction" means that current is flowing from one element to another.

[0063] Atomizer assembly 2 includes multiple independent atomizers 21, each atomizer 21 is configured to work independently when obtaining power, and a storage chamber 211 capable of accommodating a liquid matrix may be provided in atomizer 21, and the liquid matrix stored in each atomizer 21 may not exceed 5ml, for example, may be approximately 2ml. The liquid matrix may include a liquid containing a tobacco substance containing a volatile tobacco flavor component, or may be a liquid containing a non-tobacco substance. The liquid matrix may include water, liquid medicine, solvent, ethanol, plant extract, spices, flavoring agents or vitamin mixtures, etc., and spices may include betel nut extract, menthol, peppermint, green mint oil, various fruity fragrance components, etc., but are not limited thereto. Flavoring agents may include components that may provide various fragrances or flavors to the user. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C and vitamin E, but are not limited thereto. Based on the different properties of the liquid matrix, the aerosol generating device may be used in different fields, such as medical treatment, electronic aerosol atomization, etc.

[0064] The term "plurality" refers to two or more than two. Figure 4 and Figure 8 In the illustrated embodiment, there are four atomizers 21, but the present invention is not limited thereto. At least two atomizers 21 among the plurality of atomizers 21 can be used to contain different liquid matrices, and the different liquid matrices include liquid matrices with different flavors or liquid matrices with different ingredients and proportions, so that different sensory experiences can be provided to the user by switching the atomizers 21. Of course, in one embodiment, the liquid matrices contained in all the atomizers 21 can be the same.

[0065] Each atomizer 21 may also include an atomizer core 212, which is in fluid communication with the storage chamber 211, and is used to atomize the liquid matrix so that the liquid matrix generates an aerosol. The atomizer core 212 may include a liquid absorbing element and a heating element, and the liquid absorbing element may be a porous body or fiber, which can absorb the liquid matrix and guide the liquid matrix to the atomization range of the heating element; the heating element is used to atomize at least part of the liquid matrix on the liquid absorbing element to form an aerosol. The heating element may be combined with the liquid absorbing element so that the heating element can form a whole with the heating element.

[0066] Each atomizer 21 may also have an air supply channel 213, which provides at least a portion of the air flow channel for fluid communication between the atomizer core 212 and the mouthpiece assembly 4. The aerosol generated by atomization of the atomizer core 212 enters the mouthpiece assembly 4 through the air flow channel. The storage cavity 211 may be arranged around the air supply channel 213, or the air supply channel 213 may be arranged on one side of the storage cavity 211. At least a portion of the mouthpiece assembly 4 may be held in the mouth of a user, and the user inhales the aerosol by inhaling the mouthpiece assembly.

[0067] In one example, the atomizer 21 may have an atomizing compartment fluidly connected to the storage chamber 211, the atomizing core 212 is contained in the atomizing compartment, the air supply channel 213 is fluidly connected to the atomizing compartment, and the storage chamber 211 is located between the nozzle assembly 4 and the atomizing compartment. For example, the nozzle assembly 4 is located above the storage chamber 211, and the atomizing compartment is located below the storage chamber 211.

[0068] Alternatively, in another example, reference may be made to Figure 3 At least part of the atomizer core 212 is arranged in the air supply channel 213. A liquid conducting hole is provided on the air supply channel 213. The atomizer core 212 is fluidically connected to the storage chamber 211 through the liquid conducting hole. The liquid matrix in the storage chamber 211 can pass through the liquid conducting hole to be absorbed by the liquid absorption element and atomized by the heating element, or part of the liquid absorption element can pass through the liquid conducting hole into the storage chamber 211 to absorb and conduct the liquid matrix.

[0069] Please refer to Figure 3 Each atomizer 21 may further include a first flexible member 214 having a first air channel 2141, the first flexible member 214 is disposed adjacent to the mouthpiece assembly 4, the first air channel 2141 is in fluid communication with the atomizer core 212 in the atomizer 21, that is, the first air channel 2141 provides at least a portion of the air flow channel connecting the atomizer core 212 and the mouthpiece assembly 4, and the first flexible member 214 may seal the upper end of the corresponding storage chamber 211. In one example, the first air channel 2141 is in fluid communication with the air channel tube 213, and the first air channel 2141 is in fluid communication with the atomizer core 212 through the air supply channel 213, and the upper end of the air supply channel 213 is fixed by the first flexible member 214, for example, the upper end of the air supply channel 213 is embedded in the flexible member 214 and fixed while being communicated with the first channel 2141.

[0070] Please refer to Figure 3 Each atomizer 21 may further include a second flexible member 215 having a second air passage 2151, the second flexible member 215 being disposed at an end opposite to the first flexible member 214, and the second flexible member 215 may seal the lower end of the corresponding storage chamber 211, and the storage chamber 211 is located between the first flexible member 214 and the second flexible member 215. The second air passage 2151 is in fluid communication with the atomizer core 212 in the atomizer 21, and air outside the atomizer 21 may enter the air supply channel 213 through the second air passage 2151, and volatiles formed by atomizing the liquid matrix of the atomizer core 212 are combined with air entering from the second air passage 2151 to form an aerosol.

[0071] You can refer to Figure 2, the power supply assembly 3 includes a power supply 31 and a circuit board 32. The power supply 31 may include any suitable battery. The battery may be a rechargeable battery, or the battery may be a disposable battery. In one embodiment, the battery is a lithium-ion battery. Alternatively, the battery may be a nickel metal hydride battery, a nickel cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or a lithium polymer battery.

[0072] The circuit board 32 has one or more control circuits, which can control the power output by the battery, for example, making the battery output AC current or DC current, or making the battery output current or voltage in the form of pulses.

[0073] The circuit board 32 has a plurality of power supply modules 321, and the power supply assembly 3 provides power to the corresponding atomizer 21 through the power supply modules 321. In one example, the number of power supply modules 321 is less than the atomizer 21, so the atomizer 21 and the power supply module 321 can be relatively moved or relatively rotated to make the power supply module 321 switch the atomizer 21 electrically connected thereto. In one example, the number of power supply modules 321 can be more than the atomizer 21. In one example, there are a plurality of power supply modules 321, and the number of power supply modules 321 is equal to the number of atomizers 21, so that the plurality of power supply modules 321 and the plurality of atomizers can be electrically connected one-to-one or associated one-to-one, and each atomizer 21 can be electrically connected to a different power supply module 321, respectively.

[0074] Based on the first aspect of the present application, multiple atomizers 21 are electrically connected to multiple power supply modules in a one-to-one correspondence, and after the aerosol generating device is assembled, the atomizer 21 is configured so that the power supply module 321 electrically connected thereto cannot be switched, and the aerosol generating device is configured so that all the atomizers 21 cannot work at the same time to generate aerosol, and at the same time only some of the atomizers 21 can draw power from the power supply module 321 associated therewith and generate aerosol.

[0075] Based on this, in one embodiment, switch elements corresponding to multiple power supply modules 321 are set, and the user can control the selected switch element by inputting instructions, so that the power supply module 321 corresponding to the switch element can provide power to the corresponding atomizer 21, so that the corresponding atomizer 21 can obtain power to start working and enter the standby state or working state.

[0076] It should be noted that the "standby state" of the atomizer described in the present application means that as long as the power supply provides power to the power supply module, the power supply module can provide power to the corresponding atomizer. In other words, the atomizer in the standby state needs to wait for further instructions, and the further instructions are used to allow the power supply to provide power to the corresponding atomizer through the power supply module. After receiving the further instructions, the atomizer can enter the working state. The further instructions can be the user's puffing action, or other. For example, when the atomizer is in the standby state, the user can input a start instruction through the instruction input component (the instruction input component includes but is not limited to a puffing detector, a key switch, a sliding switch, a touch switch, an induction switch, a remote control switch or a touch screen, etc.), and the power supply component makes the power supply electrically conductive with the corresponding power supply module based on the start instruction, so that the power supply component can provide power to the corresponding atomizer through the power supply module, so that the atomizer is in a working state and generates an aerosol.

[0077] The "working state" of the atomizer described in the present application means that the power source is already providing power to the corresponding atomizer through the power supply module, and the atomizer is in a state of using power to generate aerosol.

[0078] Alternatively, in another embodiment, each power supply module 321 includes a first electrode group 322 and a second electrode group 323, and multiple atomizers 21 are electrically connected to different first electrode groups 322, respectively. The power supply module 321 is configured to output power to the atomizer 21 associated therewith through the first electrode group 322 contained therein.

[0079] Among them, the first electrode group 322 and the second electrode group 323 in the same power supply module 321 are associated with each other, that is, the electrical connection between the electrodes in the second electrode group 323 or the impedance of the line between the electrodes in the second electrode group 323, etc., will affect whether the line between the associated first electrode group 322 and the power supply 31 is disconnected, or whether the power supply 31 can output power through the first electrode group 322 associated with the second electrode group 323. For example, when the connection between the two electrodes in the second electrode group 323 is disconnected, the first electrode group 322 associated with the second electrode group 323 is therefore disconnected from the line between the power supply 31, so that the power supply 31 cannot provide power to the first electrode group 322, nor can it output power to the corresponding atomizer assembly 2 through the first electrode group 322.

[0080] As an example, multiple atomizers 21 are electrically connected to multiple first electrode groups 322 in a one-to-one correspondence. When the power supply component 3 outputs power through one of the first electrode groups 322, the atomizer 21 electrically connected to the first electrode group 322 can draw power from the first electrode group 322, so that the atomizer 21 starts working and enters a working state. The heating element in the atomizer 21 can atomize the liquid gas, and then the atomizer 21 can generate an aerosol.

[0081] Each atomizer 21 may include a third electrode group 216, and the number of electrodes in the third electrode group 216 may be equal to the number of electrodes in the first electrode group 322 electrically connected to the atomizer 21. Figure 12-14 In the embodiment shown, the number of electrodes in the third electrode group 316 and the number of electrodes in the first electrode group 322 are both two. Fig.16 In the illustrated embodiment, the number of electrodes in the third electrode group 216 and the number of electrodes in the first electrode group 322 are both three. The electrodes in the third electrode group 216 can be connected one-to-one with the electrodes in the first electrode group 322 electrically connected to the atomizer 21, and the connection can be detachably connected, such as elastically abutting, or the connection can be inseparable, such as welding.

[0082] Alternatively, the atomizer 21 does not include the third electrode group 216 . Instead, each atomizer 21 further includes a lead wire connected to the heating element. The lead wire extends outside the atomizer 21 and is then electrically connected to the corresponding first electrode group 322 .

[0083] You can refer to Figure 3 The atomizer assembly 2 is connected to the circuit board 32 so that the atomizer assembly 2 and the circuit board 32 cannot rotate relative to each other.

[0084] More specifically, the atomizer assembly 2 includes a first bracket 22, and a plurality of atomizers 21 are fixed on the first bracket 22, so that the plurality of atomizers 21 simultaneously remain relatively stationary with the first bracket 22. The power supply assembly 3 includes a second bracket 33, and a circuit board 32 can be combined with the second bracket 33, so that the circuit board 32 can remain relatively stationary with the second bracket 33.

[0085] As an example, the second bracket 33 has an anti-rotation member 34 extending to be inserted into the atomizer assembly 2, or the first bracket 22 has an anti-rotation member extending to be inserted into the power supply assembly 3, or the first bracket 22 and the second bracket 33 are integrally formed. Thus, the first bracket 22 and the second bracket 33 cannot rotate relative to each other, so that the atomizer 21 and the circuit board 32 cannot rotate relative to each other.

[0086] like Figure 3 As shown, the anti-rotation member 34 may pass through the circuit board 32 .

[0087] In such Figure 3 In the illustrated embodiment, the anti-rotation member 34 has a third air passage 341, the anti-rotation member 34 extends from the second bracket 33, one end of which is inserted into the second flexible member 215 of the atomizer 21 correspondingly arranged thereto, and the third air passage 341 in the anti-rotation member 34 is in fluid communication with the second air passage 2151 in the second flexible member 215, and air enters the second air passage 2151 through the third air passage 341, and then enters the air supply channel 213. There may be a plurality of anti-rotation members 33 having the third air passage 341, and at least two anti-rotation members 34 are respectively inserted into two different atomizers 21, so that the third air passages 341 in different anti-rotation members 34 are in fluid communication with different air supply channels 213, respectively.

[0088] As an example, see Fig. 9 The aerosol generating device further comprises a threaded connector, wherein the threaded connector 5 connects the first bracket 22 and the second bracket 33, so that the first bracket 22 and the second bracket 33 are fixed to each other and cannot rotate relative to each other.

[0089] The threaded connector 5 can be threadedly connected to both the first connector 22 and the second connector 33. The threaded connector 5 can connect the centers of the first bracket 22 and the second bracket 33. The second bracket 33 can have an anti-rotation member 34 as shown in the above embodiment, and the threaded connector 5 can pass through the anti-rotation member 34. The threaded connector 5 can be spaced apart from the atomizer 21.

[0090] The power source 31 may be fixed on the second bracket 33. Part of the second bracket 33 may form a component of the housing of the aerosol generating device, that is, part of the second bracket 33 may be exposed to the outside and may be grasped or touched by a user.

[0091] Please refer to Figure 5-Figure 8The aerosol generating device further comprises a conductive member 1, which is configured to rotate relative to the circuit board 32 and the atomizing assembly 2 at the same time, so that the conductive member 1 can be selectively connected to at least one of the power supply modules 321, or the conductive member 1 can be driven to change the position of the conductive member 1 so that the conductive member 1 can be sequentially abutted with multiple power supply modules 321, and the conductive member 1 can be rotated so that the conductive member 1 can switch the power supply module 321 abutted with it. When the power supply module 321 is abutted by the conductive member, the conductive member 1 can establish a conductive path between the power supply module 321 selected to be connected with it and the corresponding atomizer 21, so that the atomizer 21 associated with the power supply module 321 is in a standby state or a working state, so that the conductive member 1 can be rotated to abut against different power supply modules 321, or to abut against different power supply modules 321 in turn, so that different atomizers 21 can be in a standby state or a working state, so that the user can select the atomizer 21 in a standby state or a working state to generate aerosol after receiving further instructions or directly.

[0092] The conductive component 1 may abut against the power supply module 321 by abutting against the second electrode group 323 in the power supply module 321 .

[0093] As an example, see Fig.13 When the second electrode group 323 is abutted by the conductive member 1, the conductive member 1 is connected in series between the associated first electrode group 322 / atomizer 21 and the power source 31. Therefore, when the power source 31 outputs power to the atomizer 21 through the first electrode group 322, the output current / voltage of the power source 31 must be transmitted to the corresponding first electrode group 322 through the conductive member 1; when the conductive member 1 is removed from the second electrode group 323, the line between the power source 31 and the first electrode group 322 associated with the second electrode group 323 is disconnected.

[0094] There can be only one conductive member 1, or the conductive member 1 can only abut against one of the second electrode groups 323 at the same time, so that only one atomizer 21 among the multiple atomizers 21 can be in the standby state or in the working state at the same time.

[0095] It should be noted that having only one conductive component 1 is optional but not mandatory, and it is optional but not mandatory that the conductive component 1 abuts only one of the second electrode groups 323 at the same time. In other embodiments, there may be multiple conductive components 1, or the conductive component 1 can abut multiple second electrode groups 323 at the same time, so that the power supply 31 can provide power to multiple power supply modules 321 at the same time, so that multiple atomizers 21 can be in standby state or working state at the same time.

[0096] As an example, the conductive member 1 may rotate relative to the first bracket 22 and the second bracket 33 at the same time, but the conductive member 1 and the first bracket 22 and the second bracket 33 may be spaced apart from each other.

[0097] As an example, see Figure 2 The conductive component 1 is rotatably connected to the first bracket 22 and / or the second bracket 33, so that the conductive component 1 can rotate relative to the first bracket 22 and the second bracket 33 at the same time.

[0098] Based on this, we can refer to Fig.11 The conductive member 1 may be provided with a first positioning mechanism 11, and the first bracket 22 or the second bracket 33 may be provided with a second positioning mechanism 35. When the conductive member 1 abuts against at least one second electrode group 323, the first positioning mechanism 11 and the second positioning mechanism 35 are interlocked to prevent the conductive member 1 from continuing to rotate relative to the first bracket 22 and / or the second bracket 33, thereby ensuring that the conductive member 1 maintains a stable electrical connection with the corresponding second electrode group 323, and ensuring that the power supply 31 can stably provide power to the first electrode group 322 associated with the second electrode group.

[0099] There are many ways to release the interlock between the first positioning mechanism 11 and the second positioning mechanism 35 . One way is to provide a greater force to drive the conductive component 1 to rotate relative to the first bracket 22 and / or the second bracket 33 .

[0100] Or based on this, you can refer to Fig.11 The conductive member 1 may be provided with a first positioning mechanism 11, the first bracket 22 or the second bracket 33 may be provided with a second positioning mechanism 35, and the first positioning mechanism 11 may be rotated to correspond to the second positioning mechanism 35, for example, the first positioning mechanism 11 may be rotated to fit with the second positioning mechanism 35. The aerosol generating device is configured to generate a sensory prompt signal when the first positioning mechanism 11 is rotated to correspond to the second positioning mechanism 35, so as to prompt that the conductive member 1 is in contact with at least one of the second electrode groups 323.

[0101] The sensory prompt signal may be one or more of sound, light, and vibration. The sensory prompt signal may be a vibration signal or a sound signal generated when the first positioning mechanism 11 is rotated to engage with the second positioning mechanism 35. Alternatively, the signal acquisition circuit on the circuit board 32 may generate an electrical parameter change when the first positioning mechanism 11 is rotated to correspond to the second positioning mechanism 35, and then the control circuit may control the LED light, the player, or the motor to generate one or more of the signals of sound, light, and vibration based on the change of the electrical parameter.

[0102] As an example, see Figure 2The aerosol generating device also includes a connecting member 12, the conductive component 1 is held on the connecting member 12, and the conductive component 1 can rotate synchronously with the connecting member 12, a first accommodating chamber 14 is formed inside the connecting member 12, at least a part of the atomizer assembly 2 is accommodated in the first accommodating chamber 14, and the atomizer assembly 2 accommodated in the first accommodating chamber 14 cannot rotate relative to the circuit board 32 in the first accommodating chamber 14.

[0103] Based on the second aspect of the present application, the nozzle assembly 4 is configured to be rotatable relative to the atomizer assembly 2. When the nozzle assembly 4 is rotated relative to the atomizer assembly 2, the atomizer 21 connected to the fluid of the nozzle assembly 4 can be switched, so that the air supply channels 213 of different atomizers 21 can be connected to the fluid of the nozzle assembly 4 through rotation.

[0104] Based on this, in one example, you can refer to Figure 3 The mouthpiece assembly 4 includes an airway tube 41. When the user holds at least a portion of the mouthpiece assembly 4, the first end of the airway tube 41 is in the user's mouth, and the second end opposite to the first end is arranged in the direction of the atomizer assembly 2. The aerosol generating device is provided with a partition 121, which extends in the radial direction of the atomizer assembly 1, and the partition 121 is between the airway tube 41 and the atomizer assembly 2. Part of the partition 121 is open, so that at least one of the multiple atomizers 21 can be in fluid communication with the airway tube 41, and at the same time, the partition 121 can simultaneously block the airflow channel between the remaining one or more atomizers 21 and the airway tube 41.

[0105] For more specific information, please refer to Figure 3 , the first airway 2141 on the first flexible member 214 of one of the atomizers 21 is not blocked by the partition 121, so the atomizer 21 is in fluid communication with the mouthpiece assembly 4, and the aerosol generated by the atomizer 21 can be transferred to the airway tube 41 by the airflow channel, and then inhaled into the mouthpiece by the user. The first flexible members 214 of the remaining atomizers 21 are all elastically lower than the partition 121, so that the first airways 2141 of the first flexible members 214 on these atomizers 21 are sealed or blocked by the partition 121. Therefore, at the same time, only one atomizer 21 of the multiple atomizers 21 can be in fluid communication with the mouthpiece assembly 4, and the remaining atomizers 21 are in a closed state.

[0106] In one example, refer to Figure 3 The nozzle assembly 4 is configured to be statically connected to the connecting piece 12, so that the conductive component 1 can rotate together with the nozzle assembly 4 relative to the circuit board 32 and the atomizer assembly 2. Therefore, when the nozzle assembly 4 is rotated, while the nozzle assembly 4 selects the atomizer 21 in fluid communication with it, the conductive component 1 can select the second electrode group 323 to abut against it; and vice versa.

[0107] It can be arranged so that the atomizer 21 corresponding to the second electrode group 323 abutting against the conductive member 1 and the atomizer 21 in fluid communication with the mouthpiece assembly 4 are the same atomizer 21, so that a rotation operation can make the first electrode group 322 associated with the second electrode group 323 provide power to the corresponding atomizer 21, so that the atomizer 21 is in a working state, and at the same time, the aerosol generated by the atomizer 21 can be introduced into the mouthpiece assembly 4 through the airflow channel and finally inhaled into the mouthpiece by the user.

[0108] When the nozzle assembly 4 is statically connected to the conductive member 1, the conductive member 1 can be driven to rotate relative to the atomizer assembly 2 and the circuit board 32 by driving the nozzle assembly 4 to rotate. Alternatively, the nozzle assembly 4 can be driven to rotate relative to the atomizer assembly 2 by driving the conductive member 1 to rotate.

[0109] More specifically, the conductive component 1 can be made of a conductive material, the conductive component 1 abuts against the second electrode group 323 , and the connecting member 12 connects the conductive component 1 and the nozzle assembly 4 .

[0110] At least part of the connector 12 and the conductive member 1 may be made of the same material. At least part of the connector 12 may be made of an insulating material. The connector 12 and the conductive member 1 may be formed into an integral structure by an insert injection molding process. The connector 12 and the conductive member 1 may be integrally stamped. The conductive member 1 may be combined with the connector 12 in an assembled manner, for example, the conductive member 1 may be snap-connected to the connector 12, or embeddedly connected, etc.

[0111] As an example, see Figure 6 and Figure 8 The conductive member 1 is made of metal, such as copper, and has a contact pin 131 and a main body 132. The main body 132 is used to connect with the connector 12. The contact pin 131 is configured to contact with the power supply module 3231. The contact pin 131 can rotate synchronously with the connector 12 through the main body 132. The contact pin 131 and the main body 132 can be integrally formed. Please refer to Figure 6 The main body 132 may be configured in a ring shape, which is a closed shape, and the abutting foot 131 extends toward the inner side of the ring. Figure 8 The main body 132 may be configured to be an arc shape, which is a curved but not closed shape, and the abutting foot 131 extends toward the inner side of the arc shape. It should be noted that the main body 132 may also be in other shapes.

[0112] The number of the abutting pins 131 and the number of electrodes in the second electrode group 323 may be equal, and each abutting pin 131 may abut against each electrode in the second electrode group 323 in a one-to-one correspondence. Figure 6In the example shown, the number of the abutting pins 131 is two, and correspondingly, the number of electrodes in the second electrode group 323 is also two. Figure 8 In the example shown, the number of the abutting pins 131 is three, and correspondingly, the number of electrodes in the second electrode group 323 is also three.

[0113] The abutment between the abutment pin 131 and the power supply module 321 may be elastic abutment to ensure that the electrical connection between the conductive member 1 and the corresponding power supply module 321 is stable. Based on this, the abutment pin 131 and / or the electrodes in the second electrode group 323 have elasticity. For example, the abutment pin 131 may include a spring sheet and a contact point disposed on the spring sheet for abutting the power supply module.

[0114] The connector 12 may have a first accommodating cavity 14 for accommodating at least part of the atomizer assembly. The first accommodating cavity 14 may be disposed between the nozzle assembly 4 and the circuit board 32 .

[0115] The connecting member 12 may have a second accommodating cavity 15 inside, and at least a part of the suction nozzle assembly 4 may be accommodated in the second accommodating cavity 15, and the suction nozzle assembly 4 is configured to be unable to rotate in the second accommodating cavity 15. Figure 5 In the illustrated embodiment, a portion of the connecting member 12 forms the partition 121 described in any of the above embodiments, and the partition 121 defines at least a portion of the boundary of the bottom of the second accommodating cavity 15 .

[0116] In one example, refer to Figure 2 and Figure 5 The aerosol generating device further comprises a rotating member 16, at least a portion of which may extend into the interior of the atomizing assembly 2, and the rotating member 6 is configured to rotate relative to the atomizing assembly 2. The nozzle assembly 4 and the conductive member 1 are both statically connected to the rotating member 6, so that when the rotating member 6 rotates relative to the atomizing assembly 2, the nozzle assembly 4 and the conductive member 1 also rotate relative to the atomizing assembly 2.

[0117] The nozzle assembly 4 can be driven to rotate to drive the rotating member 6 to rotate, and then the rotating member 6 can drive the conductive member 1 to rotate. Alternatively, the conductive member 1 can be driven to rotate to drive the rotating member 6 to rotate, and then the nozzle assembly 4 can be driven to rotate by the rotating member 6. Alternatively, the atomizer assembly 2 is arranged around the rotating member 6.

[0118] Thus, the conductive component 1 can rotate together with the suction nozzle assembly 4 relative to the circuit board 32 and the atomizer assembly 2. Therefore, when the suction nozzle assembly 4 is rotated, while the suction nozzle assembly 4 selects the atomizer 21 in fluid communication with it, the conductive component 1 can select the second electrode group 323 to abut against it; and vice versa.

[0119] In such Figure 2In the illustrated embodiment, one end of the rotating member 6 is statically connected to the nozzle assembly 4 , and the other end of the rotating member 6 passes through the atomizer assembly 2 and is rotatably connected to the power supply assembly 3 . The conductive component 1 is disposed on the periphery of the rotating member 6 .

[0120] It should be noted that the rotating member 6 is optional but not mandatory. Fig. 9 In the illustrated embodiment, no rotating member capable of rotating along with the suction nozzle assembly 4 is provided on the inner side of the atomizing assembly 2 .

[0121] Based on the third aspect of the present application, the nozzle assembly 4 is configured to be in fluid communication with the air supply channels of a plurality of atomizers 21 at the same time.

[0122] Based on the third aspect, as an example, the nozzle assembly 4 is configured to be able to rotate relative to the atomizer assembly 2, but when the nozzle assembly 4 rotates relative to the atomizer assembly 2, it does not affect the simultaneous fluid communication between the nozzle assembly 4 and the air supply channels of the multiple atomizers 21. Based on this, the conductive member 1 can be statically connected to the nozzle assembly 4, so that the conductive member 1 can rotate relative to the atomizer assembly 2 together with the nozzle assembly 4. Or based on this, the rotation of the conductive member 1 relative to the atomizer assembly 4 and the rotation of the nozzle assembly 4 relative to the atomizer assembly 2 are independent and unrelated, and there may be no connection or transmission relationship between the nozzle assembly 4 and the conductive member 1.

[0123] Based on the third aspect, as an example, the nozzle assembly 4 is configured to be unable to rotate relative to the atomization assembly 4 and the circuit board 32 .

[0124] As the fourth aspect of the present application, the aerosol generating device also includes a puff detector 7 for detecting whether the aerosol generating device is puffed. The puff detector 7 is connected to the circuit board 32. The circuit board 32 is configured to control the power supply 31 to output power to the corresponding atomizer 21 through the power supply module 321 abutted by the switch component 1 when the puff detector 7 detects that the aerosol generating device is puffed, thereby causing the atomizer to generate aerosol.

[0125] Based on the fourth aspect, as an example, the aerosol generating device has an air inlet channel inside, and the air inlet channel fluid connects the air outside the aerosol generating device and the air supply channel of the atomizer 21. When the aerosol generating device is inhaled, the air outside the aerosol generating device enters the air supply channel 213 through the air inlet channel, and the air flow rate, air flow direction or air pressure in the air inlet channel will change.

[0126] The position where the puff detector 7 is arranged is connected to the fluid of the air intake channel, or the puff detector 7 is arranged in the air intake channel. The puff detector 7 is configured to detect the flow rate and direction of the air or to detect the air pressure. Therefore, when the aerosol generating device is puffed, the puff detector 7 can generate electrical parameter changes due to the changes in the air flow rate, air flow direction or air pressure at its position, thereby judging whether the aerosol generating device is puffed based on the electrical parameter changes.

[0127] The puff detector 7 can constitute a start switch for the power supply 31 to provide power to the atomizer assembly 2. When the conductive component 1 has been in contact with at least one power supply module 321, that is, the atomizer 21 is already in standby mode, if the user inhales the aerosol generating device, the puff detector 7 can detect the puff due to the change in electrical parameters generated by the puff. The circuit board 32 controls the power supply 31 to provide power to the power supply module 321 based on the result of the puff detection. The power supply module 321 then provides power to the corresponding atomizer through the first electrode group 322 therein, so that the atomizer 21 is in working state and generates aerosol. After the puff stops, based on the detection result of the puff detector 7, the circuit board 32 controls the automatic interruption of the power supply 31 to provide power to the power supply module 321, so that the corresponding atomizer 21 stops continuing to generate aerosol.

[0128] The air intake passage can be fluidly connected to the air supply passages 213 of multiple atomizers 21 at the same time, and when the puff detector 7 is constructed as a starting switch for the power supply 31 to provide power to the atomizer assembly 2, if the position where the puff detector 7 is set is fluidly connected to the air intake passage, or the puff detector 7 is set in the air intake passage, only one puff detector 7 is needed to enable the power supply 31 to output power to the corresponding atomizer 21 through the power supply module 321 abutted by the switch component 1.

[0129] It should be noted that the puff detector 7 constituting the start switch for the power supply 21 to provide power to the atomizer assembly 2 is optional but not mandatory. The start command can also be input through other command input components (command input components include but are not limited to push switches, sliding switches, touch switches, induction switches, remote control switches or touch screens, etc.) to enable the power supply 31 to output power to the corresponding atomizer 21 through the power supply module 321 abutted by the switch component 1.

[0130] Based on the fifth aspect of the present application, each atomizer 21 or each power supply module 321 in the aerosol generating device has unique identity information. The circuit on the circuit board 32 can identify the identity information and distinguish different atomizers 21 or power supply modules 321 based on different identity information. Then, the circuit on the circuit board 32 can correspondingly record, store and use the status, properties or usage level, remaining service life and other usage parameters of different atomizers 21 or power supply modules 321.

[0131] The circuit board 32 has an identification circuit, and the identification circuit is configured to identify the identity information of the power supply module 321 or the atomizer 21 when the conductive member 1 abuts against at least one power supply module 321, and then identify the power supply module 321 or the atomizer 21. The control circuit is configured to obtain the identification result of the identification circuit, thereby determining the power supply module 321 or the atomizer 21 to which power is provided based on the identification result, and simultaneously obtain the use parameters of the determined power supply module 321 or the atomizer 21.

[0132] Based on this, the aerosol generating device includes a plurality of identity circuits, and the plurality of identity circuits are associated with a plurality of power supply modules 321 or a plurality of atomizers 21 in a one-to-one correspondence. Different identity circuits carry different identity information. For example, each identity circuit has identity information for identifying the corresponding power supply module 321 or atomizer 21. Different power supply modules 321 or atomizers 21 can be identified by the identity circuit, so the identification circuit can identify the power supply module 321 or atomizer 21 corresponding to the identity information by identifying the identity information. In one example, the identity information includes the impedance of the identity circuit corresponding thereto, and the impedance includes at least one of reactance, capacitive reactance, and inductive reactance. Different identity circuits have different impedances, so the identification circuit can identify the identity circuit by identifying the impedance of different identity circuits, and identify the power supply module 321 or atomizer 21 associated with the identity circuit.

[0133] You can refer to Fig.14 and Fig.16 , the identity circuit has an identification resistor Rx. For the convenience of description, the following description is only based on four power supply modules, and the four power supply modules 321 are respectively defined as the first power supply module, the second power supply module, the third power supply module and the fourth power supply module. The identity circuits corresponding to the four power supply modules are the first identity circuit, the second identity circuit, the third identity circuit and the fourth identity circuit. The identification resistors on the first identity circuit, the second identity circuit, the third identity circuit and the fourth identity circuit are the first identification resistor R1, the second identification resistor R2, the third identification resistor R3 and the fourth identification resistor R4, respectively. The impedances of the first identification resistor R1, the second identification resistor R2, the third identification resistor R3 and the fourth identification resistor R4 are different.

[0134] As an example, see Figure 14-16The identity circuit is connected in parallel with at least part of the power supply module 321 associated therewith, or with the atomizer 21 associated therewith, or with the heating element in the atomizer 21 associated therewith, so that when the identity circuit is in operation, it does not affect the voltage output by the power supply module 321 to the corresponding atomizer 21, or does not affect the voltage obtained by the atomizer 21 from the corresponding power supply module 321, or does not affect the working voltage of the heating element in the atomizer 21. It is intended not to affect the electrical power of the heating element in the atomizer 21 to atomize the liquid matrix.

[0135] For more specific information, please refer to Figure 14-16 , the identity circuit and the second electrode group 323 in the power supply module 321 associated therewith can be connected in series, so when the conductive member 1 abuts against the second electrode group 323, at least two electrodes in the second electrode group 323 are electrically connected, at this time, the conductive member 1 is connected in series with the identity circuit, and the conductive member 1 is connected in series with the first electrode group 322 at the same time, and the identity circuit is connected in parallel with the first electrode group 322. Thus, when the conductive member 1 is rotated to abut against at least one second electrode group 323, the identity circuit associated with the second electrode group 323 is therefore electrically connected to the identification circuit on the circuit board 32, so that the identification circuit can start to identify the identity circuit, and the circuit board 32 starts to record and store the corresponding data of the associated power supply module 321 and / or the atomizer 21. When the conductive member 1 is rotated to be separated from the second electrode group 323 in the power supply module 321, the line between the identification circuit and the identity circuit associated with the power supply module 321 is disconnected, and the identification circuit stops recording the use parameters of the power supply module 321 and / or the atomizer 21. In this example, the identity circuit is connected in series with the second electrode group 323 and in parallel with the first electrode group 322, so that the operation of the identity circuit does not affect the power output by the first electrode group 322 to the atomizer 21, and further does not affect the electric power of the heating element in the atomizer 21 to atomize the liquid matrix.

[0136] It should be noted that other circuit connection methods can also be used to ensure that the identity circuit does not affect the electrical power of the heating element in the atomizer 21 to atomize the liquid matrix when it is running. This application will not illustrate each of them here.

[0137] As an example, the identity circuit is arranged on the circuit board 32. Each power supply module 321 is uniquely connected to the identity circuit. The identification circuit on the circuit board 32 includes a controller MCU and a sampling resistor R5. The controller MCU is configured to obtain a first electrical parameter of the sampling resistor R5, which may be a voltage across the sampling resistor R5 or a current flowing through the sampling resistor R5. Then, based on the first electrical parameter of the sampling resistor R5, the controller MCU obtains the identity information of the identity circuit corresponding to the power supply module 321 being abutted by the conductive member 1, for example, the impedance of the identity circuit corresponding to the power supply module 321 being abutted by the conductive member 1 is calculated based on the first electrical parameter of the sampling resistor R5.

[0138] For more specific information, please refer to Fig.15 , the identity circuit can be connected in series with the sampling resistor R5, so that the controller MCU can calculate the voltage on the identity circuit based on the voltage division on the sampling resistor R5, and then calculate the impedance of the identity circuit. The calculation formula can be roughly as follows: Among them, r5 is the resistance value of the sampling resistor, U5 is the voltage across the sampling resistor, Ux=U-U5, U is the total voltage applied to the corresponding power supply module 321, and rx is the impedance of the identification resistor on each identity circuit. In other words, the impedance rx of the first identification resistor R1 on the first identity circuit is r1, the impedance rx of the second identification resistor R2 on the second identity circuit is r2, the impedance rx of the third identification resistor R3 on the third identity circuit is r3, and the impedance rx of the fourth identification resistor R4 on the fourth identity circuit is r4.

[0139] Multiple identity circuits are connected in parallel so as not to interfere with each other. The circuit board 32 may have only one identification circuit; or may have only one sampling resistor R5, so multiple identity circuits can be connected in series with the same sampling resistor R5. Alternatively, the circuit board 32 may have multiple sampling resistors R5, and the multiple sampling resistors R5 are connected in series with the multiple identity circuits in a one-to-one correspondence.

[0140] The circuit where the identity circuit is located is defined as the first circuit, and the first electrode group 322 can be set on a second circuit in parallel with the first circuit. The heating element in the atomizer 21 is electrically connected between two electrodes in the first electrode group 322, so that the heating element in the atomizer 21 is connected in parallel with the first circuit, and the resistance value of the second circuit includes the resistance value of the heating element in the atomizer 21.

[0141] Therefore, the resistance value of the first circuit can be much greater than the resistance value of the second circuit, for example, the resistance value of the first circuit can be at least 800 times greater than the resistance value of the second circuit, so that the first circuit is almost short-circuited by the second circuit, or the first circuit is almost open-circuited, thereby reducing the power consumption of the first circuit.

[0142] In one example, the resistance value of the heating element of the atomizer 21 is between 0.75Ω and 1.5Ω, the resistance value on the second circuit is less than 3Ω, and the resistance value r5 of the sampling resistor R5 is about 300KΩ.

[0143] In one example, the resistance value of the heating element of the atomizer 21 is between 0.75Ω-1.5Ω, and the resistance value of the identification resistor Rx in the identity resistor is between 0.8KΩ-30KΩ. For example, the resistance value r1 of the first identification resistor R1 on the first identity circuit may be approximately 1KΩ, the resistance value r2 of the second identification resistor R2 on the second identity circuit may be approximately 1.5KΩ, the resistance value r3 of the third identification resistor R3 on the third identity circuit may be approximately 3KΩ, and the resistance value r4 of the fourth identification resistor R4 on the fourth identity circuit may be approximately 25.5KΩ.

[0144] In one example, refer to Fig.15 , the second circuit also has a detection resistor R6, the detection resistor R6 and the heating element of the atomizer 21 are connected in series on the second circuit, the controller 21 is configured to detect the second electrical parameter of the detection resistor R6, the second electrical parameter can be the voltage across the detection resistor R6 or the current flowing through the detection resistor R6, and judge whether the second circuit or the atomizer 21 is abnormal based on the second electrical parameter of the detection resistor R6, for example, the voltage provided by the power supply module 321 to the atomizer 21 is obtained based on the second electrical parameter of the detection resistor R6, and then the control circuit can judge whether the atomizer 21 is short-circuited or open-circuited based on the voltage provided by the power supply module 321 to the atomizer 21. The control circuit can make a corresponding response when an abnormality occurs in the second circuit or the atomizer 21 (such as a short circuit or open circuit), for example, controlling the aerosol generating device to send an alarm signal, or controlling the termination of the electrical conduction between the power supply 31 and the power supply module 321, so as to protect the atomizer 21 and / or the power supply module 321 from short circuit or open circuit. When the second electrical parameter of the detection resistor R6 is normal, the first switch Q1 can be controlled to be turned on.

[0145] Based on this, we can refer to Fig.15 The second circuit is provided with a first switch Q1 and a second switch Q2, the second switch Q2 is connected in series with the detection resistor R6, and the second switch Q2 and the detection resistor R6 connected in series are connected in parallel with the first switch Q1 as a whole, so when one of the first switch Q1 and the second switch Q2 is turned on, the second circuit is turned on, and the power supply 31 can provide power to the corresponding atomizer 21, and when the first switch Q1 is turned on, the detection resistor R6 is short-circuited.

[0146] Therefore, when the atomizer 21 needs to be short-circuited or open-circuited, the first switch Q1 can be turned off and the second switch Q2 can be turned on. At other times, the second switch Q2 can be turned off and the first switch Q1 can be turned on to reduce energy consumption on the second circuit.

[0147] The first switch Q1 and the second switch Q2 may both be connected to the controller MCU, and the controller MCU may control the first switch Q1 to be turned on or off, and the controller MCU may control the second switch Q2 to be turned on or off.

[0148] In one example, refer to Figure 14-16 The circuit board 32 has an anode terminal VCC and a cathode terminal GND, and multiple power supply modules 321 are connected in parallel between the anode terminal VCC and the cathode terminal GND. The power supply 31 provides power to the power supply modules 321 through the anode terminal VCC and the cathode terminal GND.

[0149] As an example, Fig.15 As shown, the controller MCU can be connected to the anode side of the detection resistor R6, and the cathode side of the detection resistor R6 is connected to the cathode end GND, so that the controller MCU can detect the voltage across the two ends of the detection resistor R6.

[0150] As an example, Fig.15 As shown, multiple atomizers 21 connected to the circuit board 32 can share a cathode, one end of multiple identity circuits can be connected to a common anode, and the other end is connected to the cathode end GND through the sampling resistor R5. The controller MCU can be connected to the anode side of the sampling resistor R5, and the cathode side of the sampling resistor R5 is connected to the cathode end GND, so that the controller MCU can detect the voltage across the sampling resistor R5.

[0151] Since multiple atomizers 21 are connected with a common cathode, or since the atomizer 21 and the sampling resistor R5 are connected with a common cathode, in order to prevent the current backflow on the first circuit from causing the inability to identify the identity circuit, when the identification circuit needs to identify the identity circuit, the controller MCU can control the second switch Q2 to be turned on and the first switch Q1 to be turned off; after the identity circuit is identified and the identity of the corresponding power supply module 321 or the atomizer 21 is confirmed, the controller MCU can control the first switch Q1 to be turned on and the second switch Q2 to be turned off.

[0152] After the controller MCU confirms the identity of the power supply module 321 abutted by the conductive component 1, or after the controller MCU confirms the identity of the atomizer 21 associated with the power supply module 321 abutted by the conductive component 1, the controller MCU can control the control circuit on the circuit board 32 to collect the usage parameters of the power supply module 321 or the atomizer 21, and the usage parameters include the cumulative usage time, the remaining usage time, the cumulative number of puffs or the remaining number of puffs, etc. The usage parameters can be used to determine whether the liquid matrix in the corresponding atomizer 21 is exhausted, the remaining service life, etc., or whether it is necessary to switch the power supply module 321 abutted by the conductive component 1.

[0153] The control circuit may also be configured to stop the power supply component 3 from providing power to the atomizer 21 , or provide an indication, when the usage parameter of the atomizer 21 is lower than a threshold value or exceeds a preset threshold range.

[0154] When the usage parameters include the cumulative number of puffs, the puff detector 7 can assist the control circuit in detecting whether the aerosol generating device is puffed. The control circuit can accumulate the number of puffs according to the detection result of the puff detector 7 to form a cumulative number of puffs. When the cumulative number of puffs reaches a threshold, the control circuit can control the sensory prompter to respond to prompt the user. At the same time, the control circuit can control the electrical disconnection between the power supply 31 and the power supply module 321, so that the power supply 31 cannot output power to the atomizer 21 through the power supply module 321.

[0155] When the usage parameter includes the remaining number of puffs, a storage unit corresponding to each power supply module 321 or atomizer 21 is further provided in the circuit board 32, and the total number of puffs that can be puffed of the atomizer 21 is stored in the storage unit, wherein the remaining number of puffs is the difference between the total number of puffs that can be puffed and the cumulative number of puffs. When the remaining number of puffs is reduced to a threshold value, the control circuit can control the sensory prompter to respond to prompt the user, and at the same time, the control circuit can control the electrical disconnection between the power supply 31 and the power supply module, so that the power supply 31 cannot output power to the atomizer 31 through the power supply module 321.

[0156] When the usage parameters include the accumulated usage time, the control circuit can obtain the accumulated time of the power output by the corresponding first electrode group 322, and the accumulated time can be used as the basis for determining the accumulated usage time. When the accumulated usage time reaches a threshold, the control circuit can control the sensory prompter to respond to prompt the user. At the same time, the control circuit can control the electrical disconnection between the power supply 31 and the power supply module 321, so that the power supply 31 cannot output power to the atomizer 21 through the power supply module 321.

[0157] When the usage parameters include the remaining usage time, the circuit board 32 is further provided with a storage unit corresponding to each power supply module 321 or the atomizer 21, and the total usable time of the atomizer 21 is stored in the storage unit, wherein the remaining usage time is the difference between the total usable time and the cumulative usage time, and when the remaining usage time is reduced to a threshold value, the control circuit can control the sensory prompter to respond to prompt the user, and at the same time the control circuit can control the electrical disconnection between the power supply 31 and the power supply module 321, so that the power supply 31 cannot output power to the atomizer 21 through the power supply module 321.

[0158] It should be noted that the usage parameter may also be other parameters that can indicate the usage data or usage level of the corresponding power supply module 321 or the atomizer 21, or the usage parameter may be a parameter used to indicate the amount of liquid matrix in the storage chamber 211 or the remaining amount of liquid matrix in the storage chamber 211.

[0159] When the control circuit detects that the atomizer 21 corresponding to a certain identity information is unable to continue to generate aerosol or reaches a condition that needs to be switched, the sensory prompter is controlled to respond to prompt the user. At the same time, the control circuit can control the electrical disconnection between the power supply 31 and the power supply module 321, so that the power supply 31 cannot output power to the atomizer 21 through the power supply module 321.

[0160] By rotating the conductive component 1 relative to the atomizer assembly 2 and the circuit board 32, when the conductive component 1 is rotated to abut against the power supply module 321 that has been abutted, if the atomizer 21 associated with the power supply module 321 has previously reached a condition where it can no longer generate aerosol or needs to be switched, then after the atomizer 21 is identified by the identification circuit through the identity circuit associated with the atomizer 21, the control circuit can immediately control the sensory prompter to respond again to prompt the user, and at the same time the control circuit can control the electrical disconnection between the power supply 31 and the power supply module 321, so that the power supply 31 cannot output power to the atomizer 21 through the power supply module 321.

[0161] It should be noted that, in other embodiments, reference may be made to Fig.16 The identity circuit may be disposed in the atomizer 21. The identity circuit may be connected in parallel with the heating element in the atomizer 21. Alternatively, in other embodiments, the identification circuit may be disposed in the atomizer 21. Alternatively, in other embodiments, both the identity circuit and the identification circuit may be disposed in the atomizer 21.

[0162] It should be noted that, in other embodiments, the number of power supply modules 321 on the circuit board 32 is less than the number of atomizers 21, for example, there are four atomizers 21, but there is only one power supply module 321. Therefore, only part of the atomizers 21 can be electrically connected to the power supply module 321. Therefore, the power supply module 321 can switch to be electrically connected to the atomizer 21 electrically connected thereto by making the atomizer assembly 2 and the circuit board 32 move relative to each other. In this embodiment, the identity circuit is arranged on the atomizer assembly 2, and the identification circuit can be arranged on the circuit board 32 or can be arranged on the atomizer assembly 2. When the power supply module 321 is moved to be electrically connected with the atomizer 21 in the atomizer assembly 2, the control circuit can control the identification circuit to perform identity information identification on the atomizer 21 to identify the usage parameters of the atomizer 21, and after completing the identity identification, the control circuit can control the recording and storage of the usage parameters of the atomizer 21. When the usage parameters of the atomizer 21 reach a preset value, the control circuit can control the sensory prompter to respond to prompt the user. At the same time, the control circuit can control the electrical disconnection between the power supply 31 and the power supply module 321, so that the power supply 31 cannot output power to the atomizer 21 through the power supply module 321.

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