Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to an aerosol generating device. Background Technology

[0002] Aerosol generating devices are used to generate aerosols for users to inhale.

[0003] In related technologies, some aerosol generating devices are equipped with multiple atomizers, which can produce aerosols of different flavors for users to inhale. By setting a movable mouthpiece, users can change the position of the mouthpiece so that the channels inside the mouthpiece connect with different atomizers, thereby selecting different flavors of aerosol.

[0004] During the process of inhaling aerosols, some aerosols will condense in the channels inside the mouthpiece. When the user changes the position of the mouthpiece, the condensate may leak onto the outer surface of the aerosol generating device, which is not conducive to the user's operating experience. At the same time, after the mouthpiece position is switched, the condensate may mix with other flavored aerosols, which is not conducive to the user's inhalation experience. Utility Model Content

[0005] In view of this, the present invention aims to provide an aerosol generating device that can achieve flavor switching without changing the position of the mouthpiece as a whole.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0026] In some embodiments, one of the nozzle and the switching assembly is provided with a plurality of stop grooves and the other is provided with an elastic member. The stop grooves are spaced apart along the movement direction of the switching assembly, and one side of the stop groove is open. At least a portion of the elastic member is capable of elastic deformation in the open direction of the stop groove, so that at least a portion of the elastic member can be inserted into or detached from the stop groove through the open position of the stop groove. In the first working state, at least a portion of the elastic member is inserted into one stop groove, and in the second working state, at least a portion of the elastic member is inserted into another stop groove.

[0027] In some embodiments, one of the nozzle and the switching assembly is provided with a limiting groove, and the other is provided with a limiting protrusion. The limiting groove extends along the movement direction of the switching assembly, and one side of the limiting groove is open. At least a portion of the limiting protrusion is embedded in the limiting groove through the open position of the limiting groove.

[0049] This application provides an aerosol generating device, see below. Figures 1 to 5 The aerosol generating device includes a mouthpiece 10, a switching assembly 20, and multiple atomizers 30.

[0050] The atomizer 30 includes a through airflow channel 30a.

[0051] The nozzle 10 is provided with a through discharge channel 10a, which is connected to the outside of the aerosol generating device.

[0052] The switching component 20 is provided with a blocking part 20a and multiple through flow channels 20b. The switching component 20 includes a first working state and a second working state. In the first working state, the blocking part 20a blocks part of the airflow channel 30a, and another part of the airflow channel 30a is connected to the discharge channel 10a through the flow channel 20b. In the second working state, each airflow channel 30a is connected to the discharge channel 10a through the flow channel 20b.

[0053] The switching component 20 is rotatably configured relative to the mouthpiece 10 and the atomizer 30 to switch between a first operating state and a second operating state.

[0054] The switching component 20 is rotatable relative to the mouthpiece 10 and the atomizer 30, meaning that the user can drive the switching component 20 to rotate directly or through other devices, so as to change the position and orientation of the switching component 20 relative to the aerosol generating device mouthpiece 10 and the atomizer 30.

[0055] The airflow channel 30a is provided with an airflow inlet for airflow to enter from outside the aerosol generating device and an airflow outlet for airflow to exit, so that airflow can pass through the airflow channel 30a.

[0056] The atomizer 30 stores an aerosol generating matrix. The atomizer 30 can atomize the aerosol generating matrix. The atomized aerosol generating matrix enters the airflow channel 30a and mixes with the airflow to form an aerosol before being discharged from the aerosol generating device for the user to inhale.

[0057] The mouthpiece 10 is used by the user to inhale the aerosol during the inhalation process, and the outlet formed by the discharge channel 10a and the external connection of the aerosol generating device can be connected to the user's oral cavity.

[0058] In the first working state, the airflow in a part of the airflow channel 30a is blocked by the shielding part 20a and cannot enter the discharge channel 10a. The other part of the airflow channel 30a is connected to the discharge channel 10a through the flow passage 20b, so that the aerosol in the part of the airflow channel 30a can be inhaled by the user through the mouthpiece 10.

[0059] It should be noted that, in the first working state, the number of airflow channels 30a blocked by the blocking part 20a can be one or more, such as two, three, four, five, etc.; the number of airflow channels 30a connected by the flow channel 20b can be one or more, such as two, three, four, five, etc.

[0060] In the second working state, all airflow channels 30a are connected to the exhaust channel 10a through the flow channel 20b, so that all atomizers 30 can generate aerosols simultaneously for the user to inhale.

[0061] The aerosol generating device in this embodiment allows the user to switch between a first and second operating state via the movable switching component 20, which facilitates the selection of different types of aerosols and enriches user choices. The blocking effect of the shielding part 20a reduces the probability of condensate formed from the aerosol in the isolated airflow channel 30a in the first operating state entering the discharge channel 10a, thus reducing the probability of condensate flowing out of the aerosol generating device and the probability of condensate mixing with aerosols generated by other atomizers 30, thereby improving the user experience. The rotational design reduces the space required for the switching component 20 during operation, making the aerosol generating device more compact.

[0062] In some embodiments, the switching component 20 includes multiple different first operating states, in which the airflow channel 30a isolated by the shielding portion 20a is different from the exhaust channel 10a.

[0063] It is understandable that in the first working state and the second working state, the switching component 20 rotates to different positions respectively.

[0064] In some embodiments, see Figure 6 and Figure 7 The switching assembly 20 includes a roller 21 and a first seal 22. The roller 21 is rotatably connected to the nozzle assembly 10. The first seal 22 is located on one side of the roller 21 along the extension direction of the rotation axis 20c of the roller 21. The roller 21 and the first seal 22 are anti-rotationally engaged. The roller 21 is provided with a first flow hole 21a that extends through it in the axial direction. The first seal 22 is provided with a second flow hole 22a that extends through it in the axial direction of the roller 21. The second flow hole 22a communicates with at least a portion of the first flow hole 21a to form a flow channel 20b. A portion of the first seal 22 forms a blocking portion 20a.

[0065] The user can drive the roller 21 to rotate directly or through other devices.

[0066] The roller 21 is rotatably connected to the mouthpiece 10, which makes it possible to switch components 20 without additional disassembly or assembly during the process of disassembling one or more atomizers 30.

[0067] The roller 21 is anti-rotationally engaged with the first seal 22, allowing the first seal 22 to rotate with the roller 21.

[0068] The roller 21 and the first seal 22 can be made of different materials. On the one hand, this helps to improve the structural strength of the roller 21 and reduce the probability that it will deform during the rotation process and fail to accurately reach the position of the first working state and the position of the second working state. On the other hand, the first seal 22 can be made of a material with lower hardness so as to improve the sealing performance by generating deformation.

[0069] In some embodiments, see Figure 6 and Figure 7 The first seal 22 is located on the side of the roller 21 near the atomizer 30. The first seal 22 can reduce the risk of aerosol spreading to other parts of the aerosol generating device through the roller 21 and the atomizer 30.

[0070] The specific material of the first sealing element 22 can be silicone, rubber, etc.

[0071] The roller 21 can be made of engineering plastics, metals, etc.

[0072] It is understandable that the multiple first flow holes 21a are rotationally symmetrical about the rotation axis 20c; the multiple second flow holes 22a are rotationally symmetrical about the rotation axis 20c.

[0073] In some embodiments, the number of first flow holes 21a is greater than the number of second flow holes 22a. The second flow holes 22a communicate with a portion of the first flow holes 21a to form a flow channel 20b. That is, a portion of the first flow holes 21a is sealed and blocked by the first seal 22. In the first and second working states, no airflow passes through these first flow holes 21a. This simplifies the manufacturing process of the first flow holes 21a in the manufacturing process of the roller 21.

[0074] It is understandable that during the rotation of the first seal 22 with the roller 21, the first seal 22 will rotate relative to the atomizer 30, thereby generating friction between the first seal 22 and the atomizer 30.

[0075] In some embodiments, see Figure 4 and Figure 6 The first sealing element 22 includes a first sealing body 221 and a plurality of first sealing skirts 222. The first sealing body 221 is anti-rotatingly engaged with the roller 21. The second flow hole 22a is provided on the first sealing body 221. The first sealing body 221 is spaced apart from the atomizer 30. The first sealing skirts 222 are arranged around the edge of the second flow hole 22a opening on the side facing the atomizer 30. The first sealing skirts 222 are clamped between the first sealing body 221 and the atomizer 30 along the axial direction of the roller 21.

[0076] The first sealing body 221 is engaged with the roller 21 to prevent rotation, thereby allowing the first sealing element 22 to rotate with the roller 21.

[0077] The first sealing skirt 222 surrounds the edge of the opening of the second flow hole 22a to form an annular structure.

[0078] The atomizer 30 contacts the first sealing skirt 222 but not the first sealing body 221. This helps to reduce the contact area between the first sealing element 22 and the atomizer 30, reducing the friction between them and reducing the resistance encountered during the rotation of the switching assembly 20.

[0079] This helps to improve the airtightness between the airflow channel 30a and the connected discharge channel 10a, and reduces the probability of aerosol diffusion to other parts of the aerosol generating device in the first and second working states.

[0080] It is understandable that the first sealing skirt 222 can undergo elastic deformation along the extension direction of the rotation axis 20c so that the first sealing skirt 222 can maintain a sealing fit with the atomizer 30.

[0081] It is understood that in the first working state, a portion of the first sealing skirt 222 surrounds the edge of the airflow outlet of a portion of the airflow channel 30a; in the second working state, the edge of the airflow outlet of each airflow channel 30a is surrounded by a first sealing skirt 222.

[0082] In some embodiments, the first sealing skirt 222 and the first sealing body 221 are an integral structure.

[0083] In some embodiments, see Figure 4 Along the extension direction of the rotation axis 20c towards the atomizer 30, the first sealing skirt 222 gradually expands. This facilitates the deformation of the first sealing skirt 222 away from the second flow hole 22a in the direction perpendicular to the extension direction of the rotation axis 20c, reducing the probability of the first sealing skirt 222 blocking the second flow hole 22a and improving airflow efficiency.

[0084] In some embodiments, see Figure 6 The first sealing element 22 includes a first sealing body 221 and a second sealing skirt 223. The second sealing skirt 223 is arranged around the edge of the shielding part 20a facing the atomizer 30. The second sealing skirt 223 is sandwiched between the first sealing body 221 and the atomizer 30 along the axial direction of the roller 21.

[0085] The atomizer 30 contacts the second sealing skirt 223 but not the first sealing body 221. This helps to reduce the contact area between the first seal 22 and the atomizer 30, reducing the friction between them and reducing the resistance encountered during the rotation of the switching assembly 20.

[0086] This helps reduce the probability that condensate in the airflow channel 30a, which is not connected to the nozzle 10, will diffuse into the aerosol generating device through the gap between the first sealing body 221 and the atomizer 30 in the first working state.

[0087] Understandably, the second sealing skirt 223 can undergo elastic deformation along the extension direction of the rotation axis 20c so that the second sealing skirt 223 can maintain a sealing fit with the atomizer 30.

[0088] It is understood that the first seal 22 includes at least one of the first sealing skirt 222 and the second sealing skirt 223.

[0089] In some embodiments, see Figure 1 , Figure 2 and Figure 8 The nozzle component 10 also includes a mounting groove 10b and a mounting through hole 10c. The mounting groove 10b communicates with the discharge channel 10a on one side along the axial direction of the switching assembly 20 and is open on the other side. The mounting through hole 10c is located on one side of the mounting groove 10b along the radial direction of the switching assembly 20 and communicates with the outside of the mounting groove 10b and the aerosol generating device. A portion of the switching assembly 20 is located in the mounting groove 10b and a portion is located in the mounting through hole 10c.

[0090] Thus, by installing the through hole 10c, the user can apply force from outside the aerosol generating device to a portion of the switching component 20 located within the through hole 10c to drive the switching component 20 to rotate, which is beneficial for the user to operate with one hand and improves operational convenience.

[0091] It is understandable that the switching component 20 may extend out of the aerosol generating device without extending through the mounting hole 10c, or it may extend out of the aerosol generating device in part through the mounting hole 10c.

[0092] In some embodiments, see Figure 7 The roller 21 includes a main body 211 and a sub-assembly 212. The main body 211 is anti-rotationally engaged with the first seal 22. The main body 211 can be inserted into the mounting groove 10b through the open position of the mounting groove 10b. At least a portion of the sub-assembly 212 can pass through the mounting through hole 10c and be connected to the main body 211.

[0093] By installing the through hole 10c, the user can drive the sub-assembly 212, which in turn drives the main body 211 and the first seal 22 to rotate.

[0094] During the assembly of the aerosol generating device, the first sealing element 22 and the main body 211, which are assembled together, can be rotatably connected to the nozzle element 10 through the open position of the mounting groove 10b. Then, the sub-assembly element 212 is connected to the main body 211 from the outside through the mounting through hole 10c. This helps to reduce the size of the mounting groove 10b, making the structure of the aerosol generating device more compact.

[0095] In some embodiments, the main body 211 and the sub-component 212 are detachably connected to facilitate subsequent disassembly and assembly of the aerosol generating device for maintenance and cleaning.

[0096] In some embodiments, there are two mounting holes 10c located on opposite sides of the nozzle 10 extending perpendicularly to the rotation axis 20c, in order to improve the convenience of the user driving the switching assembly 20.

[0097] In some embodiments, the peripheral edge of the roller 21 is provided with different types of markings so that the user can observe specific markings through the mounting through-hole 10c to determine whether the switching component 20 is in a first operating state or a second operating state.

[0098] The type of markings set on the roller 21 is not limited, such as different colors, patterns, structures, etc.

[0099] In some embodiments, see Figure 4 and Figure 9 The aerosol generating device includes a second sealing member 40, which is sandwiched between the nozzle member 10 and the switching assembly 20 along the axial direction of the switching assembly 20 and is sealed to both. The second sealing member 40 and the nozzle member 10 are anti-rotationally fitted. The second sealing member 40 is provided with a plurality of third flow holes 40a that pass through the switching assembly 20 along the axial direction. The third flow holes 40a are connected to the discharge channel 10a and are configured in a one-to-one correspondence with the airflow channel 30a. In the first working state, a portion of the airflow channel 20b is connected to a portion of the third flow holes 40a. In the second working state, each third flow hole 40a is connected to the airflow channel 20b.

[0100] In other words, the second seal 40 will not rotate with the switching component 20 during the rotation process.

[0101] In the first operating state, a portion of the aerosol discharged by the atomizer 30 can enter the discharge channel through a portion of the airflow channel 20b and a portion of the flow holes; in the second operating state, the aerosol discharged by each atomizer 30 can enter the discharge channel through each airflow channel 20b and each flow hole respectively.

[0102] Thus, the second seal 40 helps to reduce the probability of aerosols diffusing into other areas of the aerosol generating device through the gap between the nozzle 10 and the switching assembly 20 in both the first and second operating states.

[0103] The specific material of the second seal 40 can be silicone, rubber, etc.

[0104] Understandably, the second seal 40 is fixed to the nozzle 10.

[0105] For example, see Figure 4 and Figure 8 The nozzle component 10 also includes a positioning groove 10d. The positioning groove 10d is connected to the discharge channel 10a on one side along the axial direction of the switching component 20 and is open on the other side. The projection of the positioning groove 10d along the axial direction of the switching component 20 is elliptical and the projection of the second seal 40 along the axial direction of the switching component 20 is also elliptical. The second seal 40 is sealed and fitted to the inner wall of the positioning groove 10d along the radial direction of the rotation axis 20c of the switching component 20, thereby making the second seal 40 stop and cooperate with the nozzle component 10.

[0106] In some embodiments, see Figure 4 and Figure 9 The second sealing element 40 includes a second sealing body 41 and a plurality of third sealing skirts 42. The second sealing body 41 is anti-rotationally engaged with the suction nozzle 10. A third flow hole 40a is provided on the second sealing body 41. The third sealing skirts 42 are arranged around the edge of the opening of the third flow hole 40a on the side facing the switching assembly 20. The third sealing skirts 42 are sandwiched between the switching assembly 20 and the second sealing body 41 along the axial direction of the switching assembly 20.

[0107] The switching component 20 contacts the third sealing skirt 42 but not the second sealing body 41. This helps to reduce the contact area between the second seal 40 and the atomizer 30, reducing the friction between them and reducing the resistance encountered during the rotation of the switching component 20.

[0108] The third sealing skirt 42 reduces the probability of condensate and aerosols diffusing from the gap between the third seal and the switching assembly 20 to other parts of the aerosol generating device.

[0109] Understandably, the third sealing skirt 42 can elastically deform along the extension direction of the rotation axis 20c so that the third sealing skirt 42 can maintain a sealing fit with the atomizer 30.

[0110] Understandably, in the first operating state, the third sealing skirt 42 surrounds the edge of one end opening of the partial first sub-channel 20ba; in the second operating state, the third sealing skirt 42 surrounds the edge of one end opening of the partial second sub-channel 20bb.

[0111] In some embodiments, see Figure 4 Along the extension direction of the rotation axis 20c towards the atomizer 30, the third sealing skirt 42 gradually expands. This facilitates the deformation of the third sealing skirt 42 away from the third flow hole 40a in the direction perpendicular to the extension direction of the rotation axis 20c, reducing the probability of the third sealing skirt 42 blocking the third flow hole 40a and improving airflow efficiency.

[0112] In some embodiments, see Figure 4 , Figure 6 and Figure 7 The flow channel 20b includes a first sub-channel 20ba and a second sub-channel 20bb. There are multiple first sub-channels 20ba, and each first sub-channel 20ba is rotationally symmetrical about at least a portion of the blocking part 20a about the rotation axis 20c of the switching component 20. There are multiple second sub-channels 20bb, and each second sub-channel 20bb is rotationally symmetrical about the rotation axis 20c of the switching component 20.

[0113] In the first working state, part of the first sub-channel 20ba is connected to part of the airflow channel 30a.

[0114] In the second working state, each airflow channel 30a is connected to the discharge channel 10a via the second sub-channel 20bb.

[0115] Each first sub-channel 20ba is rotationally symmetrical with the shielding part 20a, such that in the first working state, the first sub-channel 20ba is connected to a part of the airflow channel 30a, and the shielding part 20a, which is rotationally symmetrical with it, isolates another part of the airflow channel 30a from the exhaust channel 10a.

[0116] Each second sub-channel 20bb is rotationally symmetrical to each other, so that each second sub-channel 20bb can connect to any airflow channel 30a in the second working state, thereby reducing the angle of rotation required for the switching component 20 to switch to the second working state.

[0117] It is understood that the air outlets of each airflow channel 30a are rotationally symmetrical to each other, and the axis of symmetry is the same as the rotation axis 20c of the switching component 20.

[0118] In some embodiments, there are multiple blocking portions 20a, and each blocking portion 20a is respectively configured to correspond to each first sub-channel 20ba; in other embodiments, there is only one blocking portion 20a, and different parts of the blocking portion 20a are respectively configured to correspond to each first sub-channel 20ba.

[0119] It is understandable that there are multiple first flow holes 21a. A portion of the first flow holes 21a and the second flow holes 22a connected to them form a first sub-channel 20ba, and another portion of the first flow holes 21a and the second flow holes 22a connected to them form a second sub-channel 20bb.

[0120] In some embodiments, see Figure 3 The discharge channel 10a includes a confluence channel 10aa and a plurality of collection channels 10ab. The outlet of each collection channel 10ab is connected to the inlet of the confluence channel 10aa. The outlet of the confluence channel 10aa is connected to the outside of the aerosol generating device. Each collection channel 10ab is connected to a third flow hole 40a, so that multiple types of aerosols can be mixed together in the second working state.

[0121] In some embodiments, see Figure 4 , Figure 7 and Figure 10 One of the nozzle component 10 and the switching assembly 20 is provided with a plurality of stop grooves 20d, and the other is provided with an elastic member. The stop grooves 20d are spaced apart along the movement direction of the switching assembly 20, and one side of the stop groove 20d is open. The elastic member in the nozzle component 10 and the switching assembly 20 is capable of elastic deformation in the open direction of the stop groove 20d, so that the elastic member can be inserted into or removed from the stop groove 20d through the open position of the stop groove 20d. In the first working state, the elastic member is inserted into one stop groove 20d, and in the second working state, the elastic member is inserted into another stop groove 20d.

[0122] During the movement of the switching assembly 20, the inner wall of the stop groove 20d into which the elastic member is embedded can abut against the elastic member along the movement direction of the switching assembly 20 and apply force to it, thereby driving the elastic member to disengage from the open position of the stop groove 20d until the elastic member moves relative to the switching assembly 20 to the open position of the next stop groove 20d and is embedded in the stop groove 20d.

[0123] In this way, on the one hand, the stop groove 20d can play a certain limiting role, reducing the probability of the switching component 20 moving under its own gravity and external forces; on the other hand, the elastic element entering and exiting different stop grooves 20d multiple times will bring corresponding force feedback and vibration feedback, which will help users intuitively feel that the switching component 20 has moved, thus improving the user experience.

[0124] In some embodiments, see Figure 7 The switching component 20 is active in the direction of its rotation, and multiple stop grooves 20d are circumferentially spaced along the rotation axis 20c of the switching component 20. The opening of the stop grooves 20d can be axial along the rotation axis 20c or radial along the rotation axis 20c.

[0125] The specific structural form of the elastic element is not limited.

[0126] In some embodiments, see Figure 10 The elastic element is an elastic protrusion 11.

[0127] The material of the elastic protrusion 11 can be rubber, silicone, plastic, etc.

[0128] In some embodiments, see Figure 4 and Figure 7 The aerosol generating device includes a spring sheet 50, which is fixed to one of the nozzle 10 and the switching assembly 20. The spring sheet 50 includes a deformable part that can elastically deform in the opening direction of the stop groove 20d, and the deformable part forms an elastic element.

[0129] One of the nozzle assembly 10 and the switching assembly 20 is detachably connected to the spring 50, which can be replaced individually after its elasticity weakens, without the need for additional disassembly and assembly of the nozzle assembly 10 and the switching assembly.

[0130] The specific material of the shrapnel 50 can be stainless steel, plastic, etc.

[0131] In some embodiments, see Figure 4 , Figure 7 and Figure 10 One of the nozzle component 10 and the switching component 20 is provided with a limiting groove 20e, and the other is provided with a limiting protrusion 51. The limiting groove 20e extends along the movement direction of the switching component 20. One side of the limiting groove 20e is open. At least a portion of the limiting protrusion 51 is embedded in the limiting groove 20e through the open position of the limiting groove 20e. In the first working state, the limiting protrusion 51 abuts against the inner wall of one side of the limiting groove 20e along the movement direction of the switching component 20. In the second working state, the limiting protrusion 51 abuts against the inner wall of the other side of the limiting groove 20e along the movement direction of the switching component 20.

[0132] In this way, by abutting against the inner wall of the limiting protrusion 51 and the limiting groove 20e, the limiting protrusion 51 can no longer move, which helps the user to know whether the switching component 20 is in the first working state or the second working state, thus improving the user's operating experience.

[0133] In some embodiments, see Figure 7The direction of movement of the switching component 20 is its rotation direction, and the limiting groove 20e extends circumferentially along the rotation axis 20c of the switching component 20.

[0134] In some embodiments, see Figure 2 and Figure 3 The arrangement direction of the multiple atomizers 30 is the first direction. The mouthpiece 10 also includes a mounting groove 10b and a mounting through hole 10c. The mounting through hole 10c is located on at least one side of the mounting groove 10b in the second direction and communicates with the outside of the aerosol generating device. The extension direction of the rotation axis 20c of the switching component 20, the first direction and the second direction are perpendicular to each other. At least a part of the switching component 20 is located in the mounting groove 10b and partially passes through the mounting through hole 10c.

[0135] This allows the outer contour of the aerosol generating device to be larger in the first direction than in the second direction, making it easier for a portion of the switching component 20 to extend beyond the nozzle 10 through the mounting through hole 10c, and for the user to hold the aerosol generating device with one hand and turn the switching component 20 during use.

[0136] In some embodiments, see Figure 3 The atomizer 30 includes an additional storage chamber 31 and an atomizing component 32. The additional storage chamber 31 is provided with a through-through transfer channel 31a, and the atomizing component 32 is provided with an atomizing channel 32a. The atomizing channel 32a and the transfer channel 31a are connected to form at least a portion of the airflow channel 30a. The transfer channel 31a can be connected to the flow channel 20b.

[0137] The additional storage compartment 31 is provided with an additional storage chamber 31b, which is used to store the aerosol generation matrix. The transfer channel 31a is isolated from the additional storage chamber 31b.

[0138] The atomizing component 32 is provided with an atomizing core and a main storage chamber. The main storage chamber is used to store the aerosol generation matrix. The main storage chamber is in fluid communication with the atomizing core. The atomizing core can atomize the aerosol generation matrix by means of heating or other methods. The atomized aerosol generation matrix enters the atomizing channel 32a and mixes with the airflow in the atomizing channel 32a to form an aerosol.

[0139] The aerosol discharged from the atomization channel 32a has a high temperature. After passing through the transfer channel 31a, the temperature of the aerosol drops before entering the flow channel 20b. This helps to reduce the rapid aging of the components in the switching assembly 20 due to high temperature and other reasons, and helps to extend the service life of the switching assembly 20.

[0140] Understandably, the additional storage chamber 31 is removable so that a new additional storage chamber 31 can be replaced with an old additional storage chamber 31 that has depleted the aerosol generation matrix.

[0141] In some embodiments, the aerosol generating device includes multiple airflow controllers, each electrically connected to a separate atomizing component 32.

[0142] The airflow controller is used to sense changes in parameters such as airflow and air pressure inside the aerosol generating device, so as to control the operation or stop of the atomizing component 32, thereby controlling the timing of the atomizing component 32 atomizing the aerosol generating matrix.

[0143] The airflow controller corresponds one-to-one with each atomizing component 32, thereby facilitating the control of the atomizer 30 connected to the exhaust channel 10a in the first working state and the control of all atomizers 30 in the second working state to meet the user's needs.
