[0002] An aerosol generating device is a device that can atomize a liquid preparation to form an aerosol. However, in some exemplary prior arts, there is an aerosol generating device comprising a plurality of selectively usable atomizers. In order to reduce the use cost of the aerosol generating device, it is necessary to replace the atomizer when the smoke oil in the atomizer is exhausted. For example, a typical aerosol generating device includes a nozzle assembly, an atomizer assembly having a plurality of atomizers, and a power supply assembly. The power supply assembly can only be electrically connected to one of the atomizers that is connected to the nozzle assembly at the same time to provide power for the atomizer to atomize the smoke oil to generate an aerosol. Among them, the nozzle assembly is detachably connected to the atomizer assembly to expose the atomizer in the atomizer assembly by removing the nozzle assembly, so as to replace the atomizer in which the smoke oil in the atomizer assembly is exhausted, and after removing the nozzle assembly, the nozzle assembly is reconnected to the atomizer assembly in a new assembly orientation, so that the atomizer connected to the nozzle assembly can be switched.

[0064] Please refer to Figure 1-Figure 17 An embodiment of the present application provides an aerosol generating device, which includes a housing 4 and an atomizing module 2 having a plurality of atomizers 21 , wherein at least a portion of the atomizing module 2 is disposed in the housing 4 .

[0065] As used herein, "plurality" refers to two or more. Figure 7 In the embodiment shown, the atomization module 2 includes five atomizers 21, which are arranged in a ring. Fig.15 In the illustrated embodiment, the atomization module 2 includes four atomizers 21 in total, and the four atomizers 21 are arranged in a ring shape in the transverse direction.

[0066] At least two of the multiple atomizers 21 can be used to accommodate different aerosol generating matrices. Different aerosol generating matrices include solutions with different flavors or solutions with different components and proportions. Of course, in some embodiments, the aerosol generating matrices accommodated in all the atomizers 21 can be the same.

[0067] Wherein, aerosol generation matrix can comprise the liquid containing tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.Aerosol generation matrix can comprise water, liquid medicine, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture etc., and spices can comprise betel nut extract, menthol, European mint, green mint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide various fragrance or local flavor to the user.Vitamin mixture can be the mixture that is mixed with at least one in vitamin A, vitamin B, vitamin C and vitamin E, but is not limited to this.Based on the different attributes of aerosol generation matrix, aerosol generating device can be used for different fields, such as, medical treatment, electronic aerosol atomization etc.

[0068] The atomizer 21 includes a liquid cup 211 and an atomizing core 213 in a liquid storage chamber. The liquid storage chamber is used to accommodate the liquid cup 211 of the aerosol generating matrix, and the atomizing core 213 is connected to the liquid storage chamber by liquid conduction, so that the aerosol generating matrix in the liquid storage chamber can flow to the atomizing core 213, and the atomizing core 213 is used to atomize the aerosol generating matrix, so that the aerosol generating matrix generates an aerosol. The atomizing core 213 may include a liquid absorbing element and a heating element. The liquid absorbing element may include a porous body or fiber, which can absorb the aerosol generating matrix and can guide the aerosol generating matrix to the atomization range of the heating element; the heating element is used to atomize at least part of the aerosol generating matrix on the liquid absorbing element to form an aerosol. The heating element can be combined with the liquid absorbing element, so that the heating element can form a whole with the heating element. In some embodiments, there is a liquid storage cotton in the liquid cup 211, and the aerosol generating matrix is ​​adsorbed in the liquid storage cotton and is retained in the liquid cup 211. Of course, the liquid storage cotton is optional and not mandatory.

[0069] At least a portion of the wall of the liquid cup 211 may be transparent, so that a user can observe the remaining amount of the aerosol generating substrate inside the liquid cup 211 through the wall of the liquid cup 211 .

[0070] In one embodiment, at least a portion of the housing 4 has a window 41, and the window 41 includes a lens or a through hole, so that the user can observe the liquid cup 211 through the window 41. When at least a portion of the wall of the liquid cup 211 is transparent, the user can observe the remaining amount of the aerosol generating substrate inside the liquid cup 211 through the housing 4 and the liquid cup 211 in sequence. The window 41 may have one or more windows. Figure 1In the illustrated embodiment, there is one window 41, and the window 41 is arranged corresponding to the atomizer 21 electrically connected to the power supply component 3, so that the remaining amount of the aerosol generating matrix in the atomizer 21 can be observed to determine whether the atomizer 21 electrically connected to the power supply component 3 needs to be replaced.

[0071] The atomizer 21 also has an air flow channel 214, and the atomizer core 213 is arranged in the air flow channel 214. The atomizer 21 also includes a sealing cover 212, which is sealedly connected to the liquid cup 211. The air flow channel 214 passes through the sealing cover 212, and the aerosol generated by the atomization core 213 atomizing the aerosol generating matrix passes through the hole on the sealing cover 212 and then flows out of the atomizer 21.

[0072] Specifically, the nebulizer 21 may further include an airway tube, which defines at least a portion of the boundary of the airflow channel 214. In one example, the nebulizer 21 may include an atomizing compartment in fluid communication with the liquid cup 211, the atomizing core 112 is accommodated in the atomizing compartment, and the airway tube is in fluid communication with the atomizing compartment; alternatively, in another example, reference may be made to Figure 1 , at least a portion of the atomizer core 112 is arranged in the airway tube.

[0073] In one embodiment, the end of the airway tube is connected to the sealing cover 212, and the sealing cover 212 defines a part of the boundary of the airway channel.

[0074] The atomizer 21 may further include a power-taking electrode, and the heating element generates heat when powered by obtaining current from the power-taking electrode. The power-taking electrode may include a positive electrode and a negative electrode, and the positive electrode and the negative electrode may be electrically connected to opposite ends of the heating element, respectively.

[0075] In some embodiments, the aerosol generating device further includes a nozzle module 1, the nozzle module 1 includes a nozzle assembly 11 and an air guide assembly 12, the nozzle assembly 11 is provided with an air inlet 111, a user can hold at least a portion of the nozzle assembly 11 in his mouth, and inhale the aerosol generated by the atomizer 21 that is fluidically connected to the nozzle assembly 11 through the air inlet 111.

[0076] The air guide component 12 is disposed between the air inlet 111 and the atomizer 21 in the atomization module 2, and is used to provide an air guide channel 15 for air-conducting communication between one or more atomizers 21 in the atomization module 2 and the air inlet 111. The air guide component 12 may have one or more air guide channels 15.

[0077] In one embodiment, at the same time, only one air guide channel 15 on the air guide assembly 12 can be in air-conducting communication with the air inlet 111, and the air guide assembly 12 is configured to be rotatable relative to the suction nozzle assembly 11, and the air guide channel 15 in air-conducting communication with the air inlet 111 is changed by relative rotation of the air guide assembly 12 and the suction nozzle assembly 11, and then the air inlet 111 is communicated with the air flow channel 214 of at least one atomizer 21 through the air guide channel 15, and the number of atomizers 21 in the atomization module 2 that are in communication with the air inlet 111 through the air guide channel 15 is less than the number of atomizers 21. Preferably, at the same time, only one atomizer 21 of the atomization module 2 can be in communication with the air inlet 111 through the air guide channel 15.

[0078] In one embodiment, the air guide assembly 12 is configured to be rotatable relative to the atomization module 2, so as to change the atomizer 21 connected to the air inlet 111 through the air guide channel 15 through the rotation. In this embodiment, when the number of air guide channels 15 is less than the number of atomizers 21, for example, when there is only one air guide channel 15, one or more air guide channels 15 on the air guide assembly 12 can be connected to the air inlet 111 at the same time.

[0079] In one embodiment, the air guide assembly 12 is configured to be rotatable relative to the nozzle assembly 11 and the atomization module 2 at the same time, so as to change the atomizer 21 connected to the air inlet 111 through the air guide channel 15 through the rotation.

[0080] In one embodiment, the air guide assembly 12 is configured to rotate synchronously with the atomization module 2. In this embodiment, it is preferred that there are multiple air guide channels 15, and the multiple air guide channels 15 are in air-conducting communication with the multiple atomizers 21 in a one-to-one correspondence, and the number of air guide channels 15 on the air guide assembly 12 that are in air-conducting communication with the air inlet 111 is less than the number of air guide channels 15, so that when the air guide assembly 12 and the atomization module 2 rotate synchronously relative to the nozzle assembly 11, the atomizer 21 in air-conducting communication with the air inlet 111 can be changed. Preferably, when the air guide assembly 12 can rotate synchronously with the atomization module 2, only one air guide channel 15 is in air-conducting communication with the air inlet 111 and one atomizer 21 in the atomization module 2, so that only one atomizer 21 can be connected to the air inlet 111 through the air guide channel 15 at the same time.

[0081] Specifically, the air guide assembly 12 has an interference portion 16 that can interfere with the atomizer module 2 to prevent the two from rotating relative to each other. The interference portion 16 interferes with the atomizer module 2, so that the air guide assembly 12 can rotate synchronously with the atomizer module 2. The air guide assembly 12 and the atomizer module 2 can therefore rotate synchronously relative to the suction nozzle assembly 11, thereby switching the atomizer 21 connected to the suction port 111. At the same time, the suction nozzle assembly 11 is connected to the housing 4, so that at least a portion of the atomizer module 2 is rotatably disposed in the housing 4.

[0082] Thus, when the atomizer module 2 rotates in the shell 4, the air guide component 12 can rotate synchronously relative to the shell 4, so that the air guide channel 15 and the air flow channel 214 of the atomizer 21 connected thereto can always remain connected and remain relatively still when the atomizer module 2 rotates relative to the shell 4. In other words, when the atomizer module 2 rotates relative to the shell 4, the air flow channel 214 of the atomizer 21 always maintains fluid communication with the same air guide channel 15 on the air guide component 12.

[0083] In an existing aerosol generating device, when the atomization module rotates, the atomization module and the nozzle module will rotate relative to each other. Therefore, the sealing cover on the atomizer in the atomization module will be deformed or lifted due to the lateral friction force provided by the nozzle module, affecting the sealing connection between the sealing cover and the liquid cup, thereby affecting the air pressure in the liquid storage chamber or causing the aerosol generating matrix in the liquid storage chamber to leak.

[0084] However, in this embodiment of the present application, the air guide assembly 12 in the nozzle module 1, which is connected to the atomizer module 2, can rotate relative to the housing 4 synchronously with the atomizer module 2, which not only helps to reduce the wear on the sealing cover 212, but also helps to reduce the interference of the nozzle module 1 on the sealing cover 212 in the lateral direction of the atomizer 21 when the atomizer module 2 rotates, so that the sealing cover 212 and the liquid cup 211 maintain a good sealing connection effect.

[0085] Furthermore, the nozzle assembly 11 is removably connected to the housing 4, so that the atomization module 2 in the housing 4 can be exposed by removing the nozzle assembly 11 and the air guide assembly 12, and the atomization module 2 or the atomizer 21 can be replaced.

[0086] Furthermore, the nozzle module 1 is removably connected to the housing 4 as a whole, and the nozzle module 1 is removably connected to the atomizer module 2 as a whole. When the nozzle module 1 is connected to the housing 4, at least part of the nozzle module 1 is exposed to the outside, so that the nozzle module 1 can be held in the mouth of the user and can be removed from the housing 4 by the user. After the nozzle module 1 is removed, at least part of the atomizer module 2 is exposed, so the atomizer module 2 or the atomizer 21 can be replaced. After the nozzle module 1 is removed, the air guide assembly 12 having the air guide channel 15 and the nozzle assembly 11 having the air inlet 111 are removed at the same time.

[0087] In order to ensure that the nozzle assembly 11 and the air guide assembly 12 remain connected and prevent the nozzle assembly 11 from being separated from the air guide assembly 12, so that the nozzle assembly 11 and the air guide assembly 12 can be removed from the housing 4 synchronously, in one embodiment, reference can be made to Figure 1 , Figure 6 , Figure 7 and Fig.14The nozzle module 1 also includes a connecting piece 13 having an anti-detachment portion 131, the connecting piece 13 connects the nozzle assembly 11 and the air guide assembly 12, and the anti-detachment portion 131 is rotatably interfered with the nozzle assembly 11 or the air guide assembly 12 to prevent the nozzle assembly 11 from being separated from the air guide assembly 12, and when the connecting piece 12 connects the nozzle assembly 11 and the air guide assembly 12, the nozzle assembly 11 and the air guide assembly 12 can still rotate relative to each other.

[0088] In some embodiments, the aerosol generating device further includes a power supply component 3, which includes a power supply electrode. When the atomizer 21 is electrically connected to the power supply component 3, the power supply electrode 211 of the atomizer 21 is electrically connected to the power supply electrode of the power supply component 3. Specifically, the power supply electrode includes a positive electrode and a negative electrode. When the power supply electrode 211 of the atomizer 21 is electrically connected to the power supply electrode of the power supply component 3, the positive electrode and the negative electrode of the atomizer 21 are respectively abutted against the positive electrode and the negative electrode of the power supply component 3, so that the electrical connection between the atomizer 21 and the power supply component 3 is disconnectable, so as to facilitate the change of the atomizer 21 electrically connected to the power supply component 3. The power supply electrode can be an elastic electrode that can elastically abut against the power supply electrode.

[0089] As an example, the number of power supply electrodes may be equal to the number of atomizers 21, so that the power supply assembly 3 can be electrically connected to all atomizers 21 at the same time. In this example, the aerosol generating device further includes a plurality of airflow switches corresponding to the plurality of atomizers 21. When the user draws air from the inhalation port, the airflow switch is used to detect the change of airflow or air pressure in the airflow channel of the corresponding atomizer 21, so as to determine whether the airflow channel is connected to the inhalation port based on the change of the airflow or air pressure. If so, the control power supply 7 provides power to the atomizer 21 through the power supply assembly 3.

[0090] Alternatively, as an example, the number of power supply electrodes is less than the number of atomizers 21, so that the power supply component 3 cannot be electrically connected to all atomizers 21 in the atomization module 2 at the same time. Preferably, there is one and only one set of power supply electrodes, so the power supply component 3 can only be electrically connected to one of the atomizers 21 in the atomization module 2 at the same time. Based on this, in one embodiment, the atomization module 2 is configured to be rotatable relative to the power supply component 3, so that the atomizer 21 electrically connected to the power supply component 3 is changed by the relative rotation of the atomization module 2 and the power supply component 3.

[0091] In one embodiment, reference may be made to Figure 1The aerosol generating device further includes a power source 7 and a controller, wherein two electrodes of the power source 7 are electrically connected to the positive electrode and the negative electrode of the power supply component 3, respectively, and the controller is used to control the power output of the power source 7, for example, to control the power source 7 to provide power to the power supply component 3, and then to provide power to the atomizer 21 electrically connected to the power supply component 3, so that the atomizer 21 atomizes the aerosol generating matrix to generate an aerosol. The controller can also control other operations of the aerosol generating device, such as controlling the identification of the identity information of the atomizer 21 electrically connected to the power supply component 3 and adjusting the power output of the power source 7 to the power supply component 3 based on the identity information, or, for example, controlling the sensory prompters such as lights, motors, and players in the aerosol generating device to generate sensory prompt signals, etc. Among them, the power source 7 can include any suitable battery, for example, a rechargeable battery, and of course, a disposable battery.

[0092] In such Figure 1 and Figure 2 In the embodiment shown, the power supply 7 and the circuit board carrying the controller are arranged in the housing 4, and the power supply 7 is arranged on one side of the atomization module 2 in the horizontal direction, so as to be arranged in parallel with the atomization module 2. Of course, in other embodiments, the power supply 7 can also be arranged on one side of the atomization module 2 in the longitudinal direction, so as to be arranged in the longitudinal direction with the atomization module 2. And in other embodiments, reference can be made to Fig.15 The housing disposed on the periphery of the power source 7 and the housing 4 disposed on the periphery of the atomization module 2 may not be the same housing.

[0093] In one embodiment, reference may be made to Figure 2 and Fig.14 , the power supply assembly 3 includes a mounting seat 31, and the power supply electrode 33 is arranged on the mounting seat 31. The power supply assembly 3 also includes an air hole 32 arranged on the mounting seat 31, and the air hole 32 fluid is connected to the outside and the air flow channel of the atomizer 21 electrically connected to the power supply electrode. The air hole 32 can be arranged between two power supply electrodes 33. A prompt mechanism 6 can be arranged on the mounting seat 31, and when the atomization module 2 rotates relative to the power supply assembly 3 until one of the atomizers 21 is electrically connected to the power supply assembly 3, the prompt mechanism 6 sends a prompt signal, and the prompt signal includes a sound signal and / or a vibration signal. In the case Figure 1 In the illustrated embodiment, the prompting mechanism 6 includes a hard component having a spherical surface and a soft component elastically connected to the hard component.

[0094] In one embodiment, reference may be made to Figure 1 The aerosol generating device further comprises a driving assembly 5 , at least part of which is exposed outside the housing 4 for user operation. The user can drive the atomization module 2 to rotate in the housing 4 by operating the driving assembly 5 .

[0095] The driving assembly 5 may include a rotating operating part 51 that is at least partially exposed outside the outer shell 4, and also include a connecting rod 52 connecting the rotating operating part 51 and the atomization module 2. The user drives the atomization module 2 to rotate in the outer shell 4 by rotating the rotating operating part 51, thereby causing the atomization module 2 to rotate relative to the power supply assembly 3 and realizing the transformation of the atomizer 21 electrically connected to the power supply assembly 3.

[0096] The rotating operation part 51 and the atomization module 2 can be arranged on opposite sides of the mounting seat 31 . Based on this, a through hole is opened on the mounting seat 31 , and a part of the connecting rod 52 is movably arranged in the through hole.

[0097] It should be noted that the drive assembly 5 is optional but not mandatory. Fig.11 At least part of the atomization module 2 is exposed to the outside, and the user can operate the exposed part of the atomization module 2 to rotate the atomization module 2 relative to the power supply assembly 3 and / or the suction nozzle assembly 11.

[0098] In one embodiment, the air guide assembly 12 is rotatably connected to the suction nozzle assembly 11, so that the air guide channel 15 connected to the suction port 111 is changed by the relative rotation of the air guide assembly 12 and the suction nozzle assembly 11. In order to prevent the suction nozzle mouthpiece 11 from rotating with the air guide assembly 12 when the air guide assembly 12 rotates synchronously with the atomization module 2, it can be referred to Figure 2 A stopper 42 is provided on the housing 4 , and the stopper 42 interferes with the nozzle assembly 11 to prevent the nozzle assembly 11 from rotating when the atomization module 2 rotates.

[0099] For a more specific example, see Figure 1 and Figure 4 The nozzle assembly 11 includes a shell 112, and at least a part of the air guide assembly 12 is accommodated in the shell 112. In other words, at least a part of the air guide assembly 12 can rotate in the shell 112. The nozzle assembly 11 is detachably connected to the housing 4 through the shell 112.

[0100] The housing 112 can be connected to the housing 4 by snapping to achieve the detachability or removability between the two and achieve the housing 112 and the housing 4 to be relatively stationary when the atomization module 2 rotates. The housing 112 and the housing 4 can be connected by a latch, so that the housing 112 and the housing 4 can be detachable or removable after the latch is removed or moved, and achieve the housing 112 and the housing 4 to be relatively stationary when the atomization module 2 rotates.

[0101] In such Figure 1 and Figure 7In the illustrated embodiment, the nozzle assembly 11 and the atomization module 2 are arranged longitudinally, and a first groove 43 and a second groove 44 which are interconnected but extend in different directions are provided on one of the shell 112 and the outer shell 4, and a block 1121 is provided on the other. When the shell 112 and the outer shell 4 are assembled with each other, the block 1121 first slides along the first groove 43 to correspond to the second groove 44, and then the shell 112 and the outer shell 4 are rotated relative to each other, so that the block 1121 slides along the second groove 44 until the block 1121 interferes with the stopper 42 or the second groove 44 interferes with the stopper 42. Thus, under the interference fit between the block 1121 and the second groove 44, the shell 112 cannot move longitudinally along the outer shell 4, and at the same time, under the stopper 42, the shell 112 cannot rotate circumferentially along the outer shell 4, and the outer shell 4 and the nozzle assembly 11 are therefore locked with each other.

[0102] In the process of removing the nozzle module 1 from the shell 4, a force is first provided to overcome the interference of the stopper 42 on the shell 112, and then the shell 112 and the shell 4 are rotated relative to each other, so that the block 1121 is rotated to correspond to the first groove 43, and then the block 1121 is made to slide along the first groove 43, and finally the nozzle assembly 11 drives the air guide assembly 12 to separate from the shell 4 and the atomization module 2.

[0103] The first groove 43 may extend in the longitudinal direction, and the second groove 44 may extend in the circumferential direction. Preferably, the stopper 42 is disposed in the second groove 44, so that the block 1121 is disposed on the housing 112, and when the housing 4 and the housing 112 are locked with each other, the engaging portion on the block 1121 is snap-connected with the stopper 42 in the second groove.

[0104] When the nozzle assembly 11 rotates relative to the housing 4 , the air guide assembly 12 and the atomization module 2 can remain relatively still with respect to the housing 4 .

[0105] In one embodiment, reference may be made to Figure 1-Figure 14 The air guide assembly 12 includes a support member 121, and the nozzle assembly 11 or the air guide assembly 12 also includes a flexible member 122. At least a portion of the flexible member 122 is disposed around the periphery of the air guide channel 15 and elastically abuts against the housing 112 and the support member 121, so that the air inlet 111 is sealedly connected to one of the air guide channels 15. Therefore, at the same time, the air inlet 111 can be fluidically connected to the air flow channel 214 of only one atomizer 21, while the air flow channels 214 of other atomizers 21 can be airtightly isolated outside the air inlet 111 by the flexible member 122.

[0106] It should be noted that the flexible member 122 may be a component of the nozzle assembly 11, or may be a component of the air guide assembly 12. Fig.14In the embodiment shown, the flexible member 122 is a component of the nozzle assembly 11, so when the atomizer module 2 rotates, the air guide assembly 12 or the support member 121 can rotate relative to the flexible member 122, while the flexible member 122 and the housing 112 and the air inlet 111 remain relatively stationary; Figure 1 and Figure 7 In the illustrated embodiment, the flexible member 122 is a component of the air guide assembly 12 , so when the atomization module 2 rotates, the flexible member 122 can rotate relative to the air inlet 111 and the housing 112 .

[0107] The flexible member 122 may be made of a flexible material and may be elastic, for example, the flexible member 122 may include silicone or rubber. As an example, the flexible member 122 is a component of the nozzle assembly 11, a portion of the flexible member 122 is located between the support member 121 and the air inlet 111, and the flexible member 122 has an air guide hole, which seals and connects the air inlet 111 and an air guide channel 15 provided on the support member 121. As an example, the flexible member 122 is a component of the nozzle assembly 11, and the flexible member 122 has a plurality of air guide holes, one of which is a through hole and is fluidly connected to the air inlet 111, and the remaining air guide holes may be blind holes, or of course through holes, and when the atomization module 2 and the air guide assembly 12 stop rotating, the plurality of air guide holes are arranged one-to-one with the plurality of air guide channels provided on the support member 121. As an example, the flexible member 122 is a component of the air guide component 12, and has a plurality of air guide holes on the flexible member 122, which are arranged one-to-one around at least a portion of the plurality of air guide channels 15, or at least a portion of the plurality of air guide channels 15 pass through the plurality of air guide holes one-to-one.

[0108] As an example, see Fig.10, the flexible member 122 is partially arranged between the air inlet 111 and the support member 121, and partially arranged between the support member 121 and the atomizer 21 and abuts the sealing cover 212 of the atomizer 21. In this example, the sealing cover 212 may include an injection molded part, whose hardness is greater than the hardness of the flexible member 122, and the flexible member 122 abuts the injection molded part and the two are elastically abutted, so that the air flow channel 214 in the atomization module 2 is sealed and connected with the air guide channel 15 on the support member 121 in a one-to-one correspondence. In this example, the injection molded part in the sealing cover 212 can be integrally formed with the liquid cup 211 to increase the sealing effect and prevent the sealing cover 212 from being separated from the liquid cup 121; or, the injection molded part in the sealing cover 212 can be connected to the liquid cup 211 by assembly. In order to prevent leakage of the aerosol generating matrix, the sealing cover 212 also includes a flexible plug, at least part of which is located inside the liquid cup 211 and seals the injection molded part and the liquid cup 211. Alternatively, in other examples, a portion of the flexible member 122 is disposed between the support member 121 and the nebulizer 21 and abuts against a flexible plug of the nebulizer 21, the flexible plug seals one end of the liquid storage chamber and prevents leakage of the aerosol generating matrix from between the flexible plug and the liquid cup 211. In this example, the sealing cover 212 does not include an injection molded part, and the flexible plug is made of a flexible material, such as silicone.

[0109] The hardness of the support member 121 is greater than that of the flexible member 122, and the support member 121 may include plastic, metal or wood. A plurality of air guide channels 15 may pass through the support member 121. Figure 1 and Figure 7 In the embodiment shown, when the nozzle module 1 is assembled and connected with the housing 4, the support member 121 abuts against the sealing cover 212 of the corresponding atomizer 21. Figure 1 and Figure 7 In the illustrated embodiment, the sealing cover 212 includes a flexible plug, which is made of a flexible material and has elasticity, for example, the flexible plug may include silicone or rubber. The flexible plug seals one end of the liquid storage cavity and prevents the aerosol generating matrix from leaking between the flexible plug and the liquid cup 211 by interference fit with the liquid cup 211. The support member 121 elastically abuts against the flexible plug, so that the airflow channel 214 in the atomization module 2 is sealed and connected to the air guide channel 15 on the support member 121 in a one-to-one correspondence.

[0110] In such Figure 5In the illustrated embodiment, the flexible member 122 is a component of the air guide assembly 12, the support member 121 has a plurality of first tubular portions 1211, the flexible member 122 has a plurality of second tubular portions 1221, at least a portion of the first tubular portion 1211 is inserted in a corresponding second tubular portion 1221, or at least a portion of the second tubular portion 1221 is inserted in a corresponding first tubular portion 1211. In this way, a fixed connection between the flexible member 122 and the support member 121 is achieved, so that the flexible member 122 and the support member 121 can remain relatively still.

[0111] In this embodiment, a partial boundary of each air-guiding channel 15 may be defined by the first tubular body 1211, and the remaining boundary may be defined by the corresponding second tubular body 1221. Of course, the boundary of each air-guiding channel 15 may also be completely defined by the corresponding second tubular portion 1221.

[0112] In this embodiment, an end of at least one second tubular body 1221 elastically abuts against the suction nozzle assembly 11 , so that the suction port 111 is in sealing communication with one of the second tubular bodies 1221 .

[0113] In one embodiment, reference may be made to Figure 1 and Figure 4 The air guide component 12 is provided with a guide groove 1213, which extends toward the sealing cover 212 and extends to the end of the air guide component 12. The guide groove 1213 is used to guide the aerosol condensate formed in the air guide channel 15 to discharge the condensate from the air guide channel 15, prevent the condensate from accumulating in the air guide channel 15, and prevent the user from inhaling the condensate into the oral cavity. Figure 1 and Figure 4 In the illustrated embodiment, the guide groove 1213 is disposed on the inner wall of the first tubular body 1211, and can guide the condensate to the airflow channel 214 in communication with the first tubular body 1211. Under the sealing connection between the corresponding sealing cover 212 and the first tubular body 1211, the condensate can be prevented from leaking out of the first tubular body 1211 and the atomizer 21. Among them, one guide groove 1213 can be disposed on the inner side of one first tubular body 1211, or a plurality of guide grooves 1213 can be disposed. The guide groove 1213 can extend longitudinally in the first tubular body 1211, and the extension length can be greater than 1 / 2 of the longitudinal length of the first tubular body 1211.

[0114] In one embodiment, reference may be made to Figure 1 and Figure 7 The flexible member 122 is a component of the air guide component 12 , and a portion of the flexible member 122 is located between the shell 112 and the support member 121 , and provides a sealed connection between the shell 112 and the support member 121 .

[0115] In another embodiment, reference may be made to Fig.14 The nozzle module 1 further includes a sealing ring 19 , which is disposed around the support member 121 and is located between the shell 112 and the support member 121 to provide a sealed connection between the shell 112 and the support member 121 .

[0116] In one embodiment, reference may be made to Figure 1 and Figure 7 A connecting member 13 is provided for connecting the nozzle assembly 11 and the air guide assembly 12 so that the nozzle assembly 11 and the air guide assembly 12 are inseparable from each other and can rotate relative to each other. The connecting member 13 is independent of the nozzle assembly and the air guide assembly 12, and the connecting member 13 is non-rotatably connected to one of the nozzle assembly 11 and the air guide assembly 12, and is rotatably connected to the other of the two. The anti-detachment portion 131 has two groups, which are respectively used to prevent the nozzle assembly 11 and the air guide assembly 12 from detaching from the connecting member 13, so that the nozzle assembly 11 and the air guide assembly 12 can remain connected to the connecting member 13.

[0117] Specifically, please refer to Figure 1 and Figure 7 , the connecting member 13 includes a first connecting portion and a second connecting portion, the first connecting portion is connected to the support member 121, and the second connecting portion is connected to the suction nozzle assembly 11. The structure on the support member 121 connected to the first connecting portion is non-circular, and the first connecting portion is also non-circular, so that when the first connecting portion is connected to the support member 121, the two can rotate and stop synchronously. The second connecting portion is rotatably connected to the suction nozzle assembly. More specifically, the shell 112 of the suction nozzle assembly 11 has a longitudinally extending docking column 1122, and the second connecting portion is rotatably connected to the docking column 1122, including the second connecting portion being rotatably arranged in the docking column 1122, or including at least a part of the docking column 1122 being rotatably arranged in the second connecting portion. It should be noted that in other examples, the first connecting portion is rotatably connected to the support member 121, and the second connecting portion is non-rotatably connected to the suction nozzle assembly 11, so that the connecting member 13 can remain relatively stationary with the suction nozzle assembly 11.

[0118] As an example, see Figure 12-Figure 17 The connecting member 13 is a component of one of the nozzle assembly 11 and the air guide assembly 12, and is rotatably connected to the other of the two. At least one anti-detachment portion 131 can be hook-shaped, abutting against the one rotatably connected thereto to prevent the nozzle assembly 11 and the air guide assembly 12 from being separated from each other.

[0119] Specifically, please refer to Figure 12-Figure 17, the support member 121 has a circular hole 1212 at its center, the connector 13 is integrally formed with the housing 112, extends in the longitudinal direction, and passes through at least part of the circular hole 1212 on the support member 121, and the end of the connector 13 has an anti-slip portion 131, the anti-slip portion 131 hooks the support member 121, so that at least part of the connector 13 can rotate in the circular hole 1212, and the support member 121 is kept connected to the housing 112 through the anti-slip portion 131. It should be noted that in other examples, the nozzle assembly 11 is provided with a plate having a circular hole at its center, the connector 13 is integrally formed with the support member 121, extends in the longitudinal direction, and passes through at least part of the circular hole on the plate, the end of the connector 13 has an anti-slip portion 131, the anti-slip portion 131 hooks the plate, so that at least part of the connector 13 can rotate in the circular hole, and the support member 121 is kept connected to the nozzle assembly 11 through the anti-slip portion 131.

[0120] In such Figure 1 , Figure 7 , Fig.10 and Fig.15 In the illustrated embodiment, the air inlet 111 is disposed offset from the central axis of the suction nozzle assembly 11 .

[0121] Since the air guide component 12 needs to rotate synchronously with the atomization module 2, and the air guide component 12 needs to be detachably connected to the atomization module 2, the air guide component 12 and the atomization module 2 can be connected in an embedded detachable connection manner. The so-called embedded detachable connection manner means that one of the air guide component 12 and the atomization module 2 is embedded in the other, so that the air guide component 12 and the atomization module 2 can rotate synchronously, and at the same time, the embedded part can be withdrawn, so that the air guide component 12 and the atomization module 2 can be separated from each other.

[0122] In one embodiment, reference may be made to Figure 1-Figure 9 , the part of the atomizer module 2 extends to the interference part 16 embedded in the support member 121, and can be separated to interfere with the interference part 16 of the support member 121. By extending the part of the atomizer module 2 to be embedded in the interference part 16 of the support member 121, it is prevented that the air guide component 12 interferes with the sealing cover 212 of the atomizer 21 during the process of removing the nozzle module 1 from the atomizer module 2, and it can prevent the sealing cover 212 from being damaged or even separated from the liquid cup 211 under the drive of the air guide component 12, which is conducive to the sealing cover 212 continuing to stably maintain a good connection with the liquid cup 211 during the process of removing the nozzle module 1 from the atomizer module 2.

[0123] For example, see Figure 1-Figure 6, an interference portion 16 is provided on the support member 121, and the atomization module 2 further comprises a plurality of partition plates 22, at least one atomizer 21 is retained between two adjacent partition plates 22, and at least one partition plate 22 extends to be embedded in the interference portion 16, and can be detachably interfered with the support member 121. Thus, when the end of the partition plate 22 is embedded in the interference portion 16, when the atomization module 2 rotates in the housing 4, the partition plate 22 can drive the support member 121 to rotate with the atomization module 2 by interference cooperation with the support member 121, so that the air guide component 12 rotates synchronously with the atomization module 2 and the air guide component 12 rotates relative to the suction nozzle component 11. The air guide component 12 and the atomization module 2 are arranged longitudinally, and when the air guide component 12 is moved away from the atomization module 2 longitudinally, the end of the partition plate 22 can withdraw from the interference portion 16, and the air guide component 12 can therefore be separated from the atomization module 2. The interference portion 16 may include a hole or a slot disposed on the support member 121, and the hole or slot may be a through hole or a through slot that penetrates the support member 121, or the hole or slot may be a blind hole or a blind slot that does not penetrate the support member 121. The interference portion 16 may be disposed offset from the center of the support member 121, so that no matter what the shape of the interference portion 16 is, the support member 121 can be driven to rotate by the partition plate 22 when the partition plate 22 is embedded therein. Figure 3 and Figure 4 In the illustrated embodiment, the interference portion 16 comprises a strip-shaped groove disposed offset from the center of the support member 121. Figure 2 and Figure 6 In the illustrated embodiment, the end of each partition plate 22 extends to a height exceeding the end of the atomizer 21, and there are multiple interference portions 16, which are arranged one-to-one corresponding to the multiple partition plates 22, so that when the nozzle module 1 and the housing 4 are locked with each other, the ends of the multiple partition plates 22 can be inserted into the interference portions 16 one-to-one, thereby being embedded in the interference portions 16 and interfering with the air guide assembly 12.

[0124] On this basis, the atomization module 2 may further include a center rod 23, the rotation axis of the atomization module 2 coincides with the central axis of the center rod 23, and a plurality of atomizers 21 are arranged around the center rod 23. A plurality of partition plates 22 are radially connected to the center rod 23, a circular rotating hole 17 may be provided on the support member 121 corresponding to the center rod 23, the end of the center rod 23 extends to be inserted into the circular rotating hole 17, and can rotate in the circular rotating hole 17, the cooperation between the center rod 23 and the circular rotating hole 17 is conducive to coinciding the rotation axis of the air guide component 12 with the central axis of the air guide component 12.

[0125] Or, for example, see Figure 7-Figure 9, the atomization module 2 further includes a center rod 23, the rotation axis of the atomization module 2 coincides with the central axis of the center rod 23, and a plurality of atomizers 21 are arranged around the center rod 23; wherein, a non-circular hole 18 is provided on the support member 121, the interference portion 16 includes the non-circular hole 18, the end of the center rod 23 is non-circular, the end of the center rod 23 is embedded in the non-circular hole 18, and can be detachably interfered with the nozzle module 1. The non-circular end of the center rod 23 cooperates with the non-circular hole 18 on the support member 121 so that the center rod 23 and the support member 121 cannot rotate relative to each other, so when the atomization module 2 rotates in the housing 4, the center rod 23 can drive the support member 121 to rotate, so that the air guide assembly 12 rotates synchronously with the atomization module 2 and the air guide assembly 12 rotates relative to the nozzle assembly 11. The shape of the non-circular end of the center rod 23 can be the same as the non-circular hole 18 on the support member 121, for example, both are elliptical, quadrilateral, triangle, star-shaped, cross-shaped, or the residual shape after a part of the circle is cut off. Figure 7 In the illustrated embodiment, the atomization module 2 may also include a plurality of partition plates 22 , and at least one atomizer 21 may be retained between two adjacent partition plates 22 , but there may be no connection between the partition plates 22 and the air guide assembly 12 .

[0126] In combination with one or more examples or embodiments described above, when it is necessary to remove the nozzle module 1 to expose the atomizer module 2 in order to replace the atomizer module 2 or the atomizer 21: the nozzle assembly 11 can be first rotated relative to the housing 4 along the second groove 44. At this time, the nozzle assembly 11 rotates relative to the air guide assembly 12, and a part of the atomizer module 2 is still embedded in the air guide assembly 12, so that the air guide assembly 12 and the atomizer module 2 remain relatively stationary, and the air guide assembly 12 can also remain relatively stationary with the housing 4; then, the nozzle assembly 11 is moved relative to the housing 4 along the first groove 43. Under the action of the connecting member 13, the air guide assembly 12 and the nozzle assembly 11 are synchronously moved away from the atomizer module 2 under the guidance of the first groove 43. Finally, the nozzle module 1 can be removed from the housing 4, and the air guide assembly 12 can be completely separated from the atomizer module 2. Similarly, when it is necessary to assemble the nozzle module 1 with the shell 4: the nozzle assembly 11 can be first moved relative to the shell 4 along the first groove 43, and under the action of the connecting piece 13 or the mutual connection between the nozzle assembly 11 and the air guide assembly 12, the air guide assembly 12 and the nozzle assembly 11 are synchronously guided by the first groove 43 to approach the atomization module 2, so that a part of the atomization module 2 is gradually embedded in the interference portion 16 and interferes with the air guide assembly 12; then, the nozzle assembly 11 is rotated relative to the shell 4 along the second groove 44, at which time a part of the atomization module 2 is still embedded in the air guide assembly 12, so that the air guide assembly 12 and the atomization module 2 remain relatively stationary, so that when the nozzle assembly 11 rotates along the second groove 44, the nozzle assembly 11 can rotate relative to the air guide assembly 12, and at the same time, the air guide assembly 12 can also remain relatively stationary with the shell 4 until the nozzle assembly 11 and the shell 4 are locked with each other.

[0127] In one embodiment, reference may be made to Figure 10-Figure 17 The support member 121 has an insert 14, which extends into the interior of the atomization module 2 and is detachably interfered with the atomization module 2. The interference portion 16 may include the insert 14.

[0128] For example, see Figure 10-13 The insert 14 can be detachably embedded between two adjacent atomizers 21 and can be clamped by the outer side walls of the two adjacent atomizers 21 .

[0129] Specifically, the insert 14 is generally sheet-shaped, the atomizer module 2 may include a plurality of partitions 22, at least one atomizer 21 is held between two adjacent partitions 22, and the height of the partition 22 in the longitudinal direction is lower than the height of the atomizer 21, so that part of the interval between two adjacent atomizers 21 is filled with the partition 22, and part of the interval is vacant, the insert 14 is arranged corresponding to the vacant interval, and when the nozzle module 1 and the housing 4 are locked with each other, at least part of the insert 14 is embedded in the vacant interval. The thickness of the sheet-shaped insert 14 may be substantially equal to the thickness of the partition 22.

[0130] Thus, when the insert 14 is at least partially embedded in the vacant interval, when the atomizer module 2 rotates in the housing 4, the atomizer 21 can drive the support member 121 to rotate together with the atomizer module 2 through interference fit with the insert 14, so that the air guide component 12 rotates synchronously with the atomizer module 2 and the air guide component 12 rotates relative to the nozzle component 11. The air guide component 12 and the atomizer module 2 are arranged longitudinally. When the air guide component 12 is moved away from the atomizer module 2 longitudinally, the end of the insert 14 can withdraw from the corresponding vacant interval, and the air guide component 12 can therefore be separated from the atomizer module 2. Figure 10-13 In the illustrated embodiment, there are multiple inserts 14 and multiple empty intervals, and the multiple empty intervals are arranged one-to-one with the multiple inserts 14, so that when the nozzle module 1 and the shell 4 are locked with each other, the multiple inserts 14 can be inserted into the empty intervals one-to-one, so as to be embedded in the atomization module 2 and interfere with the atomization module 2.

[0131] Or for example, not shown in the figure, the insert includes a first tubular body or a second tubular body, and the first tubular body or the second tubular body is partially embedded in the hole of the sealing cover, so that the first tubular body or the second tubular body is sealedly connected to the air flow channel of the corresponding atomizer, and at the same time, the interference fit between the first tubular body or the second tubular body and the inner side wall of the corresponding sealing cover enables the air guide assembly and the atomization module to rotate synchronously.

[0132] Or, for example, see Figure 14-17 The atomization module 2 further includes a plurality of partition plates 22 , at least one atomizer 21 is held between two adjacent partition plates 22 , at least one partition plate 22 is provided with a receiving portion 221 , and the insert 14 can be detachably embedded in the receiving portion 221 .

[0133] In such Fig.15 In the illustrated embodiment, the receiving portion 221 includes a groove provided on the partition plate 22, and the shape of the end of the insert 14 is adapted to the shape of the groove and can be embedded in the groove. When at least part of the insert 14 is embedded in the groove, when the atomization module 2 rotates in the housing 4, the partition plate 22 can drive the support member 121 to rotate with the atomization module 2 through interference fit with the insert 14, so that the air guide assembly 12 rotates synchronously with the atomization module 2 and the air guide assembly 12 rotates relative to the nozzle assembly 11. When the nozzle module 1 is removed from the housing 4, the insert 14 is separated from the groove and the atomization module 2.

[0134] In this embodiment, the insert 14 and the outer side wall of the sealing cover 212 can be spaced apart and non-contacting, so that when the insert 14 is separated from the atomization module 2, it will not interfere with the sealing cover 212 of the atomizer 21 in the lateral direction of the atomizer 21, which is conducive to the sealing cover 212 to maintain a stable and good connection with the liquid cup 211.

[0135] Or for example, not shown, the atomizer module 2 includes a central rod 23, the rotation axis of the atomizer module 2 coincides with the central axis of the central rod 23, and a plurality of atomizers 21 are arranged around the central rod 23, the end of the central rod 23 is provided with a non-circular hole, at least one insert 14 on the air guide assembly 12 is non-circular, and the non-circular insert 14 extends to be detachably embedded in the non-circular hole of the central rod 23. When at least part of the insert 14 is embedded in the non-circular hole, when the atomizer module 2 rotates in the housing 4, the central rod 23 can drive the support member 121 to rotate with the atomizer module 2 by interference fit with the insert 14, so that the air guide assembly 12 rotates synchronously with the atomizer module 2 and the air guide assembly 12 rotates relative to the nozzle assembly 11. When the nozzle module 1 is removed from the housing 4, the insert 14 is separated from the non-circular hole of the central rod 23 and the atomizer module 2.

[0136] In combination with one or more examples or embodiments described above, when it is necessary to remove the nozzle module 1 to expose the atomizer module 2 to replace the atomizer module 2 or the atomizer 21: the nozzle assembly 11 can be first rotated relative to the housing 4 along the second groove 44, at which time the nozzle assembly 11 rotates relative to the air guide assembly 12, and a portion of the insert 14 on the air guide assembly 12 is still embedded in the atomizer module 2, so that the air guide assembly 12 and the atomizer module 2 remain relatively stationary at this time, and the air guide assembly 12 can also remain relatively stationary with the housing 4; then, the nozzle assembly 11 is moved relative to the housing 4 along the first groove 43, and under the action of the connecting member 13, the air guide assembly 12 and the nozzle assembly 11 are synchronously moved away from the atomizer module 2 under the guidance of the first groove 43, and finally the nozzle module 1 can be removed from the housing 4, and the air guide assembly 12 can be completely separated from the atomizer module 4. Similarly, when it is necessary to assemble the nozzle module 1 with the shell 4: the nozzle assembly 11 can be first moved relative to the shell 4 along the first groove 43, and under the action of the connecting member 13 or the mutual connection between the nozzle assembly 11 and the air guide assembly 12, the air guide assembly 12 and the nozzle assembly 11 are synchronously guided by the first groove 43 to approach the atomization module 2, so that a part of the embedding member 14 on the air guide assembly 12 is gradually embedded in the atomization module 2 and interferes with the atomization module 2; then, the nozzle assembly 11 is rotated relative to the shell 4 along the second groove 44, at which time at least a part of the embedding member 14 is still embedded in the atomization module 2, so that the air guide assembly 12 and the atomization module 2 remain relatively stationary, so that the nozzle assembly 11 can rotate relative to the air guide assembly 12, and at the same time, the air guide assembly 12 can also remain relatively stationary with the shell 4 until the nozzle assembly 11 and the shell 4 are locked with each other.

[0137] When the atomization module 2 includes both the partition plate 22 and the center rod 23 , the partition plate 22 and the center rod 23 can be integrally injection molded.

[0138] The present application also provides an aerosol generating device, which can be referred to Figure 1-Figure 9In the aerosol generating device, the nozzle module 1 is removably connected to the atomizer module 2, and the nozzle module 1 and the atomizer module 2 are embedded in interference fit, so that at least part of the nozzle module 1 can remain relatively still with the atomizer module 2, and the nozzle module 1 abuts the sealing cover 212 and is spaced apart from the side wall of the sealing cover 212, and the side wall includes the outer side wall of the sealing cover 212 and the inner side wall of the sealing cover 212, so that the nozzle module 1 has no contact interference with the sealing cover 212 in the lateral direction of the atomizer 21. Therefore, it can be avoided that the nozzle module 1 interferes with the sealing cover 212 of the atomizer 21 during the process of removing the nozzle module 1 from the atomizer module 2, and it can be prevented that the sealing cover 212 is damaged or even separated from the liquid cup 211 under the drive of the nozzle module 1, which is conducive to the sealing cover 212 continuing to be stably and well connected with the liquid cup 211 during the process of removing the nozzle module 1 from the atomizer module 2. In this embodiment, it is optional and not necessary that the atomization module 2 is rotatably arranged in the housing 4 .
