Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of aerosol generation, and in particular to an aerosol generating device. Background Art

[0002] An aerosol generating device is a device that can atomize a liquid preparation to form an aerosol. The aerosol generating device includes a power supply assembly and an atomizing assembly. The atomizing assembly has an atomizer. Since the liquid matrix stored in the atomizer cannot exceed 2ML, the number of puffs of the aerosol generating device is small, which brings a bad user experience. In some exemplary prior arts, in order to increase the number of puffs, a plurality of atomizers are provided in the atomizing assembly, and the atomizing assembly can rotate relative to the power supply assembly. By rotating, different atomizers in the atomizing assembly are electrically connected to the power supply assembly in turn, so that the atomizers in the atomizing assembly can work in turn and generate aerosol for the user to inhale.

[0003] However, the existing aerosol generating devices with multiple atomizers have the following defects: First, during the relative rotation process, the electrodes of the power supply assembly will be worn, thereby affecting the electrical connection between the electrodes and the next atomizer; Second, the user needs to remember the previous rotation direction and rotation angle, otherwise it is easy to cause the power supply assembly to be electrically connected again to the atomizer that was previously electrically connected and the liquid matrix has been exhausted through rotation.

[0016] As an example, a first viewing window is provided on the second shell, and the mark includes a second viewing window provided on the first shell. When the atomizer assembly is received in the receiving chamber, the second viewing window is arranged toward the first viewing window, so that at least a portion of the atomizer received in the working chamber is visible.

[0017] As an example, the atomizer includes a third shell and a liquid storage chamber located inside the third shell and used to store a liquid matrix. The third shell is at least partially transparent, so that at least a portion of the liquid storage chamber is visible.

[0018] As an example, the atomization assembly further includes a support member, which is detachably connected to the first shell and is used to support at least two atomizers so that the at least two atomizers are respectively maintained in the working chamber and the storage chamber.

[0019] As an example, the atomizer includes a power collection electrode, the power supply module includes a power supply electrode, and a through hole is opened on the support member, and the through hole is arranged corresponding to the power collection electrode so that the power collection electrode is exposed; when the atomization assembly is connected to the second shell, the power collection electrode and the power supply electrode abut against each other.

[0020] As an example, the support member includes a base and an operating portion, the base is detachably connected to the first shell, and the operating portion is connected to the base;

[0043] Please refer to Figure 1-Figure 5 An embodiment of the present application provides an aerosol generating device, including a main body component 2 and an atomizing component 1. The main body component 2 includes a power supply module, and the atomizing component 1 includes at least two atomizers 11, wherein the atomizer 11 electrically connected to the power supply module can generate aerosol.

[0044] In one embodiment, the atomizer 11 includes a third housing 111 and a liquid storage chamber 112 disposed inside the third housing 111 for storing a liquid matrix. The liquid matrix may include a liquid containing a tobacco substance containing a volatile tobacco flavor component, and may also include a liquid of a non-tobacco substance. The liquid matrix may include water, a liquid medicine, a solvent, ethanol, a plant extract, a flavor, a flavoring agent, or a vitamin mixture, etc. The flavoring agent may include betel nut extract, menthol, peppermint, green mint oil, various fruity flavor components, etc., but is not limited thereto. The flavoring agent may include components that can 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 is not limited thereto. Depending on the liquid, the atomizer may be used in different fields, such as medical treatment, electronic aerosol atomization, etc. At least a portion of the third housing 111 may be transparent, so that at least a portion of the liquid storage chamber is visible, so that it is convenient for the user to observe the remaining amount of the liquid matrix in the liquid storage chamber and to judge whether the liquid matrix in the liquid storage chamber is exhausted.

[0045] In one embodiment, the atomizer 11 includes an atomizing core 113, which is in fluid communication with the liquid storage chamber 112 and is used to be electrically connected to the power supply module, and can atomize the liquid matrix when power is obtained. The atomizing core 113 includes a wicking element and a heating element, and the heating element is arranged on the wicking element. The wicking element is in fluid communication with the liquid storage chamber 112, and the wicking element has capillaries or micropores, so that the liquid matrix can be adsorbed from the liquid storage chamber 112 and the liquid matrix is ​​conducted to the heating range of the heating element, so that the liquid matrix is ​​heated and atomized by the heating body to form an aerosol. The wicking element may include porous ceramics, porous glass substrates, porous plastic substrates, or porous metal substrates, etc. The wicking element may include cotton or fiber, etc. The heating element may include a heating film, a heating circuit, a heating coil, a heating sheet, or a heating net, etc.

[0046] In one embodiment, the atomizer 11 includes an air guide tube 114, which is fluidically connected to the atomizer core and is used to guide the aerosol generated by the atomizer core 113 out of the atomizer 11 for the user to inhale. At least a portion of the air guide tube 114 can pass through the liquid storage chamber 113, but is not limited thereto. There can be only one air guide tube 114. There can be multiple air guide tubes 114, for example, two, and at least a portion of the liquid storage chamber 112 is located between the two air guide tubes 114.

[0047] In one embodiment, the atomizer 11 includes an air inlet channel 115 fluidly connected to the atomizer core 113. External air flows to the atomizer core 113 through the air inlet channel 115 and then combines with the aerosol generated by the atomizer core 113, so that the aerosol forms an aerosol, which can be inhaled by the user.

[0048] In one embodiment, the atomizer 11 includes a power-taking electrode 116 electrically connected to the atomizer core 113, and the atomizer 11 is electrically connected to the power supply module through the power-taking electrode 116. The power-taking electrode 116 may include a positive power-taking electrode and a negative power-taking electrode, and the positive power-taking electrode and the negative power-taking electrode are electrically connected to opposite ends of the heating element correspondingly, so as to provide voltage to the heating element.

[0049] In one embodiment, the power supply module includes a power supply electrode 21, and the power supply module is electrically connected to the atomizer 11 through the power supply electrode 21. Specifically, when the power supply module is electrically connected to the atomizer 11, the power supply electrode 21 is electrically connected to the power extraction electrode 116. The power supply electrode 21 may include a positive power supply electrode and a negative power supply electrode. When the power supply electrode 21 is electrically connected to the power extraction electrode 116, the positive power supply electrode and the negative power supply electrode are electrically connected to the positive power extraction electrode and the negative power extraction electrode respectively.

[0050] In one embodiment, the power supply module includes a power supply 22, which is electrically connected to the power supply electrode 21, and outputs power to the atomizer 11 through the power supply electrode 21. The positive power supply electrode and the negative power supply electrode are electrically connected to the positive output electrode and the negative output electrode of the power supply 22 respectively. The power supply 22 can be any suitable power source, such as a DC source, such as a battery. In one embodiment, the power supply 22 is a lithium-ion battery. Alternatively, the power supply 22 can 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.

[0051] The power supply module may further include a control circuit, which may have one or more controllers, and the controller may be used to protect the battery or control the power output of the battery, etc. The controller may control the overall operation of the aerosol generating device.

[0052] The aerosol generating device provided as one of the exemplary embodiments of the present application has a plurality of atomizers 11, that is, at least two atomizers 11, and at least two atomizers 11 can work independently of each other and can generate aerosol independently of each other. The structural features of at least two atomizers 11 can be exactly the same. The liquid matrix stored in at least two atomizers 11 can be the same, so that aerosols of the same flavor can be generated. In some alternative embodiments, the liquid matrix stored in at least two atomizers 11 can be different, so that aerosols of different flavors can be generated. The capacity of the liquid storage chamber 112 in at least two atomizers 11 can be the same. The capacity of the liquid storage chamber in at least two atomizers 11 can be different. By providing multiple atomizers 11, the total number of puffs of the aerosol generating device is increased.

[0053] Based on this, please refer to Figure 1 , Figure 7 and Figure 8The atomizer assembly 1 further comprises a first shell 12, wherein the first shell 12 has a working chamber 121 and a storage chamber 122 arranged at intervals, at least one atomizer 11 among the plurality of atomizers 11 is removably received in the working chamber 121, at least one atomizer 11 among the plurality of atomizers 11 is removably received in the storage chamber 122, and the atomizer 11 received in the working chamber 121 and the atomizer 11 received in the storage chamber 122 are interchangeable, so that a user can make the plurality of atomizers 11 be received in the working chamber 121 in turn.

[0054] Among them, the power supply module is electrically connected to the atomizer 11 received in the working chamber 121. The user can electrically connect different atomizers 11 to the power supply module by replacing the atomizer 11 originally received in the working chamber 121 with the atomizer 11 originally received in the reserve chamber 122. Therefore, when the user needs to switch the smoking flavor or the liquid matrix in an atomizer 11 is exhausted, the atomizer 11 in the working chamber 121 can be removed, and the atomizer 11 in the reserve chamber 122 can be moved to the working chamber 121, so that the aerosol generating device can continue to be inhaled. Especially when the user cannot obtain a new atomizer or cannot obtain a new aerosol generating device from the outside world, the atomizer 11 in the reserve chamber 122 is allowed to enter the working chamber 121 and be electrically connected to the power supply module to continue to generate aerosol, which can significantly improve the user's usage experience. The atomizer 11 removed from the working chamber 121 can replace the atomizer 11 moved into the working chamber 121 from the reserve chamber 122, and be accommodated and maintained in the reserve chamber 122; of course, the user can also discard the atomizer 11 removed from the working chamber 121 and whose liquid matrix has been exhausted.

[0055] For further information, please refer to Figure 2 The main body component 2 is used to support or receive the atomizer component 1. The main body component 2 also includes a first positioning portion 241. The first positioning portion 241 interferes with the atomizer component 1 to prevent the atomizer component 1 from rotating relative to the power supply module, so that the working chamber 121 can correspond to the corresponding position of the power supply module, for example, the power-taking electrode 116 of the atomizer 11 in the working chamber 121 can correspond to the power supply electrode 21; and it can also prevent the power supply electrode 21 from being worn, so that the power supply electrode 21 can maintain a stable and reliable electrical connection with the new atomizer 11 after being electrically connected to different atomizers 11 for multiple times, and maintain a low contact resistance.

[0056] In one embodiment, reference may be made to Figure 2The atomizer assembly 1 further includes a mouthpiece 13 that can be held by a user, and the mouthpiece 13 is in fluid communication with the atomizer 11 received in the working chamber 121. The atomizer 11 received in the storage chamber 122 and the mouthpiece 13 can be isolated from each other, so that when the user draws on the mouthpiece 13, the outside air mainly enters the mouthpiece 13 through the atomizer 11 in the working chamber 121, or only the aerosol generated by the atomizer 11 in the working chamber 121 can enter the mouthpiece 13.

[0057] The nozzle 13 can be connected to the first shell 12. As an example, the nozzle 13 is detachably connected to the first shell 12, so that after the nozzle 13 is removed from the first shell 12, the working chamber 121 and the storage chamber 122 are opened, and the user can take out the atomizers 11 in the working chamber 121 and the storage chamber 122, thereby exchanging at least one atomizer 11 in the working chamber 121 with at least one atomizer 11 in the storage chamber 122. Of course, the user can also replace the original atomizer 11 in the atomization assembly 1 with a new atomizer 11 and keep it in the first shell 12. As an example, you can refer to Figure 5-Figure 7 The first shell 12 and the mouthpiece 13 are integrally formed or inseparably connected, so that when the atomizer 11 in the working chamber 121 and the storage chamber 122 are interchanged, the mouthpiece 13 and the first shell 12 can remain connected.

[0058] In one embodiment, reference may be made to Figure 2 The atomizer assembly 1 is detachably connected to the main body assembly 2. The detachable connection between the atomizer assembly 1 and the main body assembly 2 can be a snap connection, a twist connection, a magnetic connection, or a threaded connection. After the atomizer assembly 1 is separated from the main body assembly 2, the user can take out the atomizers 11 in the working chamber 121 and the storage chamber 122, and then exchange at least one atomizer 11 in the working chamber 121 with at least one atomizer 11 in the storage chamber 122. Of course, the user can replace the original atomizer 11 in the atomizer assembly 1 with a new atomizer 11 and keep it in the first housing 12.

[0059] For example, see Figure 2 and Figure 3 The main body assembly 2 includes a second shell 25 having a receiving chamber 251. When the atomizer assembly 1 is connected to the main body assembly 2, at least a portion of the atomizer assembly 1 is arranged in the receiving chamber 251, and the atomizer assembly 1 is configured to be removable from the receiving chamber 251 so as to interchange the atomizer 11 received in the working chamber 121 with the atomizer 11 received in the storage chamber 122 after removal.

[0060] As an example, see Figure 2The first housing 12 is provided with a fixing portion 123, and the first positioning portion 241 is provided on the second housing 25. When the atomizer assembly 1 is received in the receiving chamber 251, the first positioning portion 241 interferes with the fixing portion 123, thereby preventing the atomizer assembly 1 from rotating in the receiving chamber 251. When the atomizer assembly 1 is received in the receiving chamber 251, the nozzle 13 is exposed outside the receiving chamber 251 for the user to inhale.

[0061] Furthermore, the detachable connection between the atomizer assembly 1 and the main body assembly 2 is a snap connection or a twist connection between the first shell 12 and the second shell 25. Specifically, the upper end of the receiving chamber 251 is open for the atomizer assembly 1 to enter, and the second shell 25 is also provided with a second positioning portion 242. When the atomizer assembly 1 is received in the receiving chamber 251, the second positioning portion 242 is located above the fixing portion 123 and interferes with the fixing portion 123 to prevent the atomizer assembly 1 from being removed from the receiving chamber 251, thereby ensuring that when the user holds the suction nozzle 13 to inhale, the atomizer 11 in the working chamber 121 can maintain a stable electrical connection with the power supply module, and can prevent the electrical connection between the atomizer assembly 1 and the power supply module from being disconnected during the inhalation process.

[0062] In order to facilitate the atomizer assembly 1 to be received in the receiving chamber 251 and removed from the receiving chamber 251, the detachable connection between the atomizer assembly 1 and the main body assembly 2 is preferably a screw-on connection between the first shell 12 and the second shell 25. Figure 2 , the second housing 25 has a first slide groove 23 and a second slide groove 24 which are cross-arranged. One end of the first slide groove 23 extends to the upper end of the second housing 25 or is arranged adjacent to the upper end of the second housing 25, and the other end is communicated with the second slide groove 24, so that in the process of receiving the atomizer assembly 1 in the receiving chamber 251, the first slide 23 can guide the fixing portion 123 to slide into the second slide groove 24, and in the process of removing the atomizer assembly 1 from the receiving chamber 251, the fixing portion 123 slides out of the second slide groove 24, and then slides along the first slide groove 23, and finally the atomizer assembly 1 is separated from the receiving chamber 251.

[0063] The first slide groove 23 and the second slide groove 24 can be perpendicular to each other. For example, the first slide groove 23 extends along the axial direction of the receiving cavity 251, and its extension direction is parallel to the axial direction of the receiving cavity 251, while the second slide groove 24 extends along the inner surface of the second shell 25 to form an arc groove.

[0064] The intersection angle between the first slide groove 23 and the second slide groove 24 can be an obtuse angle. For example, the first slide groove 23 extends obliquely, and its extension direction intersects with the axial direction of the receiving cavity 251 so that the extension direction of the first slide groove 23 and the axial direction of the receiving cavity 251 are not parallel to each other, while the second slide groove 24 extends along the circumference of the second shell 25.

[0065] The first positioning portion 241 and the second positioning portion 242 define a portion of the boundary of the second sliding groove 24 . When the fixing portion 123 is located in the second sliding groove 24 , it can interfere with the first positioning portion 241 and the second positioning portion 242 at the same time.

[0066] In such Figure 2 In the illustrated embodiment, one end of the second sliding groove 24 is connected to the first sliding groove 23 , and the other end is a first positioning portion 241 .

[0067] In one embodiment, reference may be made to Figure 2 , the inner wall of the receiving chamber 251 defined by the second shell 25 is circular. It should be noted that the inner wall of the receiving chamber 251 defined by the second shell 25 is optional and not mandatory. In other embodiments of the present application, the inner wall of the receiving chamber defined by the second shell 25 is non-circular, such as an ellipse or a polygon, that is, the first positioning portion 241 can be at least part of the inner wall of the receiving chamber 251 defined by the second shell 25, so that at least part of the inner wall of the second shell 25 can interfere with and stop the atomizer assembly 1 to prevent the atomizer assembly 1 from rotating. When the inner wall of the receiving chamber 251 defined by the second shell 25 is non-circular, the outer wall of the first shell 12 can also be non-circular, that is, the fixing portion 123 can be at least part of the outer wall of the first shell 12, so that at least part of the outer wall of the first shell 12 can be interfered with and stopped by the main assembly 2 to prevent the atomizer assembly 1 from rotating. The shape of the first shell 12 can match the shape of the receiving chamber 251.

[0068] Alternatively, in some other embodiments, the first positioning portion 241 includes an axially extending guide rail arranged on the inner wall of the second shell 25, and when the atomizer assembly 1 enters from the upper end of the receiving chamber 251, the guide rail is slidably connected to the atomizer assembly 1, so that the atomizer assembly 1 enters the receiving chamber 251 and is maintained in a preset orientation (for example, an orientation in which the working chamber 121 corresponds to the power supply electrode 21 of the power supply assembly), and after the atomizer assembly 1 is assembled to the preset position of the receiving chamber 251, the atomizer 11 in the working chamber 121 is electrically connected to the power supply electrode 21 of the power supply assembly, and the guide rail maintains an interference fit with the atomizer assembly 1 to prevent the atomizer assembly 1 from rotating relative to the power supply module in the receiving chamber 251. Furthermore, after the atomizer assembly 1 is assembled to the preset position of the receiving chamber 251, the atomizer assembly 1 and the main body assembly 2 are snap-fitted, interference-fitted, or magnetically fitted to prevent the atomizer assembly 1 from exiting the receiving chamber, so that after the atomizer assembly 1 moves axially to the preset position along the guide rail, the atomizer assembly 1 can be locked in the receiving chamber 251 without rotating the atomizer assembly 1 in the receiving chamber 251.

[0069] In one example, the guide rail includes a first strip groove formed on the inner wall of the second shell 25, and correspondingly, a first convex strip is provided on the outer wall of the first shell 12, and when the atomizer assembly 1 enters from the upper end of the receiving chamber 251, the first convex strip is located in the first strip groove and slides along the first strip groove. In one example, the guide rail includes a second convex strip formed on the inner wall of the second shell 25, and correspondingly, a second strip groove is provided on the outer wall of the first shell 12, and when the atomizer assembly 1 enters from the upper end of the receiving chamber 251, the second convex strip is located in the second strip groove and slides along the second strip groove. The strip groove may be a blind groove, or may be a through groove penetrating the shell wall.

[0070] Alternatively, in some other embodiments, the first positioning portion 241 includes a first magnetic member disposed on the main assembly 2, and the fixing portion 123 in the atomizer assembly 1 includes a second magnetic member. When the atomizer assembly 1 is located in the receiving chamber 251, there is a magnetic force of mutual attraction or repulsion between the first magnetic member and the second magnetic member. The magnetic force is conducive to the atomizer assembly 1 automatically adjusting its orientation during the process of entering the receiving chamber 251, and helps to make the working chamber 121 correspond to the power supply electrode 21 of the power supply assembly, and after the atomizer 11 in the working chamber 121 is electrically connected to the power supply electrode 21 of the power supply assembly, the magnetic force can prevent the atomizer assembly 1 from rotating relative to the power supply module. Preferably, the magnetic force between the first magnetic member and the second magnetic member is a magnetic attraction force, so that the magnetic force can also prevent the atomizer assembly 1 from exiting the receiving chamber 251.

[0071] The first magnetic member may be a ferromagnetic member that can be attracted by a magnet, or may be a magnet or an electromagnet. The second magnetic member may be a ferromagnetic member that can be attracted by a magnet, or may be a magnet or an electromagnet. The first magnetic member may be held on the bracket 26. The second magnetic member may be held on the support member 15.

[0072] It should be noted that the first positioning portion 241 may also be other components or structural features, which are not listed one by one in this application.

[0073] In one embodiment, reference may be made to Figure 7 and Figure 8 , a mark 14 for distinguishing the working chamber 121 from the reserve chamber 122 is provided in the atomizer assembly 1, or the working chamber 121 and the reserve chamber 122 are constructed differently, for example, the cross-sectional shapes or opening shapes of the two are different, so that after the user takes out the atomizer 11 in the working chamber 121 and the atomizer 11 in the reserve chamber 122, before the atomizer 11 is installed into the first shell 12 again, the user can quickly distinguish the working chamber 121 and the reserve chamber 122, and then correctly install the corresponding atomizer 11 into the working chamber 121 and the reserve chamber 122, which can effectively avoid memory confusion and prevent the atomizer 11 taken out from the working chamber 121 from being installed into the working chamber 121 again.

[0074] When the third shell 111 is at least partially transparent so that the liquid storage chamber 112 is at least partially visible, the user can identify the atomizer 11 that can be loaded into the working chamber 121 by observing the remaining amount of liquid matrix in the atomizer 11 or observing whether the liquid matrix in the liquid storage chamber 112 has been exhausted.

[0075] Each atomizer 11 in the atomizer assembly 1 has a number or color representing its identity, and the user can use the number or color to identify the atomizer 11 that has been loaded into the working chamber 121 and the atomizer 11 that has not been loaded into the working chamber 121, or to identify the atomizer 11 that has just been taken out of the working chamber 121 and the atomizer 11 that has just been taken out of the reserve chamber 122. For example, after the user has just taken out the No. 1 atomizer 11 from the working chamber 121 and the No. 2 atomizer 11 from the reserve chamber 122, the user will not confuse the No. 1 atomizer 11 with the No. 2 atomizer 11, thereby preventing the No. 1 atomizer 11 from being loaded into the working chamber 121 again.

[0076] As an example, see Figure 7 and Figure 8 The mark 14 includes a second window 141 opened on the first shell 12 . The second window 141 is set corresponding to the working chamber 121 . The working chamber 121 can be observed through the second window 141 . The user can identify the working chamber 121 through the second window 141 .

[0077] Furthermore, a first viewing window 252 is formed on the second shell 25 . When the atomizer assembly 1 is received in the receiving chamber 251 , the second viewing window 141 is disposed toward the first viewing window 252 , so that at least a portion of the atomizer 11 received in the working chamber 121 is visible.

[0078] There may be no window on the first shell 12 corresponding to the storage cavity 122 , or the window on the first shell 12 corresponding to the storage cavity 122 may have a different size or shape from the second window 141 .

[0079] As an example, the mark 14 includes at least one of a protrusion 142, a groove, a character, and a graphic provided on the first shell.

[0080] In such Figure 8 In the illustrated embodiment, the marker 14 may further include a tubular body 143 extending in the working chamber 121, the tubular body 143 fluid being connected to the mouthpiece 13, and after the atomizer 11 is loaded into the working chamber 121, the tubular body 143 fluid is connected to the atomizer 11, so that the atomizer 11 received in the working chamber 121 is connected to the mouthpiece 13 through the tubular body 143 fluid.

[0081] In one embodiment, the atomizer assembly 1 further includes a support member 15, which is detachably connected to the first shell 12. The detachable connection between the support member 15 and the first shell 12 may be a snap connection, a twist connection, a magnetic connection, or a threaded connection. Figure 4 and Figure 5 In the described embodiment, a snap protrusion 154 is provided on the support member 15 , and a snap groove 124 is provided on the first shell 12 . When the support member 154 is connected to the first shell 15 , the snap protrusion 154 is embedded in the snap groove 124 and snap-connected with the snap groove 124 .

[0082] The support member 15 is used to support the plurality of atomizers 11 so that the plurality of atomizers 11 are kept in the working chamber 121 and the storage chamber 122. When the atomizer assembly 1 is separated from the main assembly 2, the support member 15 can prevent the atomizer 11 from falling from the working chamber 121 and the storage chamber 122, so that after the atomizer assembly 1 is separated from the main assembly 2, before the support member 15 is removed, the plurality of atomizers 11 can continue to be orderly kept in the original position without falling.

[0083] When the atomizer 11 needs to be removed from the first housing 12 , the support member 15 needs to be removed first to open the working chamber 121 and the storage chamber 122 .

[0084] In one example, refer to Figure 5 and Figure 6 The support member 15 is provided with a through hole 151, and the through hole 151 is arranged corresponding to the power-taking electrode 116 of the atomizer 11 received in the working chamber 121, so that the power-taking electrode 116 is exposed; when the atomizer assembly 1 is connected to the second shell 25, the power-taking electrode 116 and the power supply electrode 21 abut against each other. Preferably, the mutual abutment between the power-taking electrode 116 and the power supply electrode 25 is elastic. The power-taking electrodes 116 of the multiple atomizers 11 arranged in the first shell 12 can all be exposed through the through hole 151; in the case Figure 4 In the illustrated embodiment, there are a plurality of through holes 151, and the power-taking electrodes 116 of the plurality of atomizers 11 disposed in the first housing 12 are respectively exposed through different through holes 151. Of course, only the power-taking electrodes 116 of the atomizers 11 located in the working chamber 121 may be allowed to be exposed through the through holes 151, while the power-taking electrodes 116 of the atomizers 11 located in the storage chamber 122 are hidden by being blocked by the support member 15.

[0085] In such Figure 4 and Figure 5In the illustrated embodiment, a protrusion 142 is provided on the first shell 12, and an alignment groove 155 is provided on the support member 15. By aligning the protrusion 142 with the alignment groove 155, after the support member 15 is connected to the first shell 12, the power-taking electrode 116 of the atomizer 11 received in the working chamber 121 can correspond to the through hole 151, so that the power-taking electrode 116 can be exposed through the through hole 151 without being blocked by the support member 15. Of course, other methods can also be used to connect the support member 15 and the first shell 12 to each other at a preset angle and position.

[0086] In order to facilitate the user to operate the support member 15, the support member 15 is removed from the first housing 12. Figure 5 and Figure 6 In the illustrated embodiment, the support member 15 includes a base 152 and an operating portion 153. The base 152 is detachably connected to the first shell 12, and the operating portion 153 is connected to the base 152 and at least partially extends outside the first shell 12. When the atomizer assembly 1 is separated from the main assembly 2, the operating portion 153 is exposed for user operation. The user operates the operating portion 153 to apply force to the operating portion 153, thereby driving the support member 15 to separate from the first shell 12 through the operating portion 153. The operating portion 153 can be a handle that can be directly grasped by the user. Figure 5 and Figure 6 In the illustrated embodiment, the through hole 151 is opened on the base 152 .

[0087] In one example, refer to Figure 1 , Figure 2 and Fig. 9 The main assembly 2 includes a bracket 26 , and a clearance space 261 is provided on the bracket 26 corresponding to the operating part 153 . When the atomizer assembly 1 is connected to the main assembly 2 , the bracket 26 supports the base 152 , and at least a part of the operating part 153 is located in the clearance space 261 .

[0088] Furthermore, the power supply electrode 21 is fixed on the bracket 26. Based on this, in some embodiments, the first positioning portion 241 is disposed on the bracket 26, and the first positioning portion 241 prevents the atomization assembly from rotating relative to the bracket by interfering with the support member 15.

[0089] In such Figure 2 and Figure 8 In the illustrated embodiment, an air hole 262 is provided on the bracket 26 , and the air hole 262 is fluidically connected to the atomizer 11 received in the working chamber 121 . Most of the air entering the aerosol generating device needs to pass through the air hole 262 and then enter the atomizer 11 received in the working chamber 121 .

[0090] A hollow flexible member 27 is also fixed to the bracket 26. A part of the flexible member 27 is located in the air hole 262 and is interference fit with the bracket 26. Most of the air entering the aerosol generating device needs to pass through the hollow flexible member 27 and then enter the atomizer 11 received in the working chamber 121. When the atomizer assembly 1 is received in the receiving chamber 251, the flexible member 27 elastically abuts against the atomizer 11 received in the working chamber 121, so that the hollow flexible member 27 is sealedly connected to the air inlet channel 115 of the atomizer 11, which can prevent the air passing through the hollow flexible member 27 from leaking out of the atomizer 11 and prevent other atomizers 11 from being in fluid communication with the atomizer 11.

[0091] In one embodiment, reference may be made to Figure 7 and Figure 8 There are a plurality of storage chambers 122, and each storage chamber 122 is configured to receive only one atomizer.

[0092] In one embodiment, reference may be made to Figure 7 and Figure 8 , the working chamber 121 can only receive one atomizer 11 .

[0093] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. 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.
