[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410813273.1, filed on June 21, 2024, entitled "Aerosol Generating Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0004] An aerosol generating device is a device that can atomize liquid preparations to form an aerosol. However, in some exemplary prior art, there are aerosol generating devices that include multiple selectable atomizers. For example, a typical aerosol generating device includes a power supply component and an atomizing component with multiple atomizers. By rotating the atomizing component relative to the power supply component, one of the atomizers in the atomizing component is electrically connected to the output electrode of the power supply component, thereby enabling the atomizer to be activated and generate an aerosol when powered on.

[0005] However, when rotating the atomizing component relative to the power component, the user needs to use both hands. Specifically, the user needs to hold the power component with one hand and then rotate the atomizing component with the other hand, which makes switching atomizers complicated.

[0006] Application content

[0007] The purpose of this application is to provide an atomizing device that simplifies the operation of changing the atomizer electrically connected to the power supply component.

[0008] At least one embodiment of this application provides an aerosol generating device, comprising:

[0009] Power supply components;

[0010] An atomizing assembly, including a plurality of atomizers, is configured to rotate relative to the power supply assembly to change the atomizers electrically connected to the power supply assembly by rotation; and

[0011] The driving component includes an operating part for user operation and a first toothed pin linked to the operating part, wherein the first toothed pin is configured to move from a first position to a second position under the drive of the operating part;

[0012] The power supply component or the atomizing component includes a first inclined surface. During at least a portion of the travel of the first toothed foot moving from the first position to the second position, the first toothed foot abuts against the first inclined surface and slides along the first inclined surface, causing the power supply component and the atomizing component to rotate relative to each other.

[0013] As an example, the aerosol generating device also includes a reset component;

[0014] The reset assembly includes an actuator movable between a third position and a fourth position. The actuator is linked to the first tooth, such that the first tooth is reset to the first position during at least a portion of the travel of the actuator as it moves from the fourth position to the third position.

[0015] As an example, the power supply component or the atomizing component further includes a second inclined surface, and the actuating member is provided with a second tooth. The second tooth abuts against the second inclined surface and slides along the second inclined surface during at least a part of the stroke of the actuating member moving from the fourth position to the third position, so that the power supply component and the atomizing component continue to rotate relative to each other in the original rotation direction.

[0016] As an example, when the first tooth abuts against the first inclined plane, the second tooth is spaced apart from the second inclined plane; and / or

[0017] When the second tooth foot abuts against the second inclined surface, the first tooth foot is spaced apart from the first inclined surface.

[0018] As an example, the atomizing assembly also includes a support for holding the plurality of atomizers, the support having an interference portion;

[0019] The first inclined surface and the second inclined surface are formed on the interference portion, and the first tooth and the second tooth are located on opposite sides of the interference portion.

[0020] As an example, the support also includes a central tube, with a plurality of atomizers arranged around the central tube, and the rotation axis of the atomizing assembly coinciding with the central axis of the central tube;

[0021] The actuator is movably disposed inside the central tube; and / or

[0022] The first tooth is movably disposed inside the central tube.

[0023] As an example, the interference portion further includes a first stop surface for abutting against the first tooth foot located at the second position.

[0024] As an example, the interference portion further includes a second stop surface for abutting against the second tooth foot located at the third position.

[0025] As an example, when the first tooth moves from the first position to the second position, the power supply component and the atomizing component rotate relative to each other by a first angle. When the actuating component moves from the fourth position to the third position, the power supply component and the atomizing component rotate relative to each other by a second angle. The sum of the first angle and the second angle θ satisfies: θ = 360° / n, where n is the number of atomizers.

[0026] As an example, the first angle is smaller than the second angle.

[0027] As an example, the length of the second inclined plane is greater than the length of the first inclined plane; or

[0028] The length of the second inclined plane is less than the length of the first inclined plane.

[0029] As an example, the reset assembly also includes an elastic element, one end of which is connected to the actuating element and the other end of which is connected to the atomizing assembly or the power supply assembly. The elastic element is used to provide elastic force to keep the actuating element in the third position.

[0030] As an example, the drive assembly further includes a drive rod connected to the operating part, the first tooth being disposed on the drive rod, and the drive rod connecting the actuator, such that during at least a portion of the travel of the first tooth moving from the first position to the second position, the drive rod pushes the actuator from the third position to the fourth position.

[0031] As an example, the aerosol generating device further includes a mouthpiece assembly, the atomizing assembly being configured to rotate relative to the mouthpiece assembly to change the atomizer in fluid communication with the mouthpiece assembly by rotating relative to the mouthpiece assembly.

[0032] As an example, the atomizing device includes a housing, the atomizing component is rotatably disposed within the housing, and the nozzle assembly is connected to the housing, such that the atomizing component can rotate synchronously relative to the power supply component and the nozzle assembly; or

[0033] The nozzle assembly is connected to the power supply assembly, so that the power supply assembly and the nozzle assembly can rotate synchronously relative to the atomizing assembly.

[0034] As an example, the operating part and the suction nozzle assembly are located on opposite sides of the housing.

[0035] As an example, the atomizing component includes the first inclined surface, the driving component includes a driving rod connected to the operating part, and the first tooth is disposed on the driving rod;

[0036] The power supply assembly includes a mounting base, a power supply electrode disposed on the mounting base, and a through hole formed on the mounting base. The power supply electrode is detachably electrically connected to one of the atomizers in the atomizing assembly. The inner wall of the through hole includes an anti-rotation stop wall. A portion of the drive rod interferes with the anti-rotation stop wall in the through hole to prevent the first tooth from rotating relative to the power supply assembly when it moves between the first position and the second position.

[0037] As an example, the drive rod has a protrusion, a portion of which is located in the through hole and interferes with the anti-rotation stop wall, and the end of the protrusion forms the first tooth.

[0038] As an example, the second inclined plane includes a plurality of inclined surfaces that are inclined in the same direction and distributed around each other.

[0039] At least one embodiment of this application provides an aerosol generating device, comprising:

[0040] Power supply component, having power supply electrodes;

[0041] An atomizing assembly, including a first atomizer and a second atomizer, is configured to rotate relative to the power supply assembly;

[0042] The driving component includes an operating part that provides user operation, the operating part being capable of linearly moving from a first position to a second position based on the user operation;

[0043] A reset component, configured in conjunction with the operating part, is used to provide a drive to return the operating part from the second position to the first position and to hold the operating part in the first position.

[0044] The reset component can cooperate with the atomizing component during the reset stroke to drive it to rotate; when the operating part is in the first position, the first atomizer is electrically connected to the power supply electrode; when the operating part is moved from the first position to the second position by user operation and is driven back to the first position by the reset component, the reset component can drive the atomizing component to rotate by a predetermined angle, so that the second atomizer corresponds to the position of the power supply electrode and maintains electrical connection.

[0045] The atomizing device provided in the above embodiments includes a power supply component, a drive component, and an atomizing component with multiple atomizers. The atomizing component is configured to rotate relative to the power supply component to change the atomizer electrically connected to the power supply component. The drive component includes an operating part for user operation and a first toothed foot linked to the operating part. The first toothed foot is configured to move from a first position to a second position under the drive of the operating part. The atomizing component or the power supply component further includes a first inclined surface. During at least a portion of the stroke of the first toothed foot moving from the first position to the second position, the first toothed foot abuts against and slides along the first inclined surface, causing the atomizing component or the power supply component with the first inclined surface to rotate. The power supply component and the atomizing component thus rotate relative to each other. Therefore, the user can operate the atomizing device with one hand to change the atomizer electrically connected to the power supply component. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0061] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements. When an element is referred to as being "connected to" another element, it can be directly connected to the other element, or there may be one or more intervening elements.

[0062] Referring to Figures 1-3, an embodiment of this application provides an aerosol generating device, a power supply component 1, and an atomizing component 2 having a plurality of atomizers 21. The atomizing component 2 is configured to rotate relative to the power supply component 1 so as to change the atomizers 21 electrically connected to the power supply component 1 by rotation. Based on this, the plurality of atomizers 21 can be arranged in a ring.

[0063] As indicated in this application, "multiple" refers to two or more. In the embodiment shown in FIG7, the atomizing assembly 2 includes four atomizers 21 arranged in a ring.

[0064] At least two of the multiple atomizers 21 can be used to contain different liquid matrices, including solutions with different flavors or solutions with different ingredients and proportions. Of course, in some embodiments, all atomizers 21 can contain the same liquid matrices.

[0065] The liquid matrix may contain a liquid containing tobacco-based substances with volatile tobacco aroma components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavorings, etc., but are not limited to these. Flavorings may contain ingredients that can provide users with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamins A, B, C, and E, but are not limited to these. Based on the different properties of the liquid matrix, the aerosol generating device can be used in different fields, such as medical and electronic aerosol atomization.

[0066] The atomizer 21 includes a liquid cup 211 for containing a liquid matrix and an atomizing core in fluid communication with the liquid cup 211. The atomizing core atomizes the liquid matrix, causing it to generate an aerosol. The atomizing core may include a liquid-absorbing element and a heating element. The liquid-absorbing element may include a porous body or fiber, capable of absorbing the liquid matrix and guiding it to the atomization range of the heating element. The heating element atomizes at least a portion of the liquid matrix on the liquid-absorbing element, forming an aerosol. The heating element may be integrated with the liquid-absorbing element, thus forming a single unit. In some embodiments, the liquid cup 211 has a liquid-retaining cotton, in which the liquid matrix is ​​adsorbed and retained. The liquid-retaining cotton is optional, not mandatory.

[0067] At least a portion of the wall of the liquid cup 211 may be transparent, allowing the user to observe the remaining amount of liquid matrix inside the liquid cup 211 through the wall of the liquid cup 211.

[0068] In one embodiment, the atomizing device further includes a housing 6, and the atomizing component 2 can be disposed within the housing 6. At least a portion of the housing 6 has a viewing window 61, which includes a lens or a through-hole, allowing the viewer to observe the liquid cup 211 through the viewing window 61. When at least a portion of the wall of the liquid cup 211 is transparent, the viewer can sequentially observe the remaining amount of liquid matrix inside the liquid cup 211 through the housing and the liquid cup 211. There can be one or more viewing windows 61. In the embodiment shown in FIG. 1, there is one viewing window 61, and this viewing window 61 is provided corresponding to the atomizer 21 electrically connected to the power supply component 1. This allows the viewer to observe the remaining amount of liquid matrix in the atomizer 21 to determine whether it is necessary to change the atomizer 21 electrically connected to the power supply component 1.

[0069] Each of the atomizers 21 described above may further include an airway tube in fluid communication with the atomizing core, the airway tube being used to deliver aerosol. In one example, the atomizer 21 may have an atomizing compartment in fluid communication with the liquid cup 211, the atomizing core 112 being housed in the atomizing compartment, and the airway tube being in fluid communication with the atomizing compartment; alternatively, in another example, at least a portion of the atomizing core 112 is arranged in the airway tube.

[0070] Each of the atomizers 21 described above may also include a power-collecting electrode 212, and the heating element generates heat by drawing power from the power-collecting electrode 212. The power-collecting electrode 212 may include a positive electrode and a negative electrode, and the positive electrode and the negative electrode may be electrically connected to the opposite ends of the heating element, respectively.

[0071] The power supply assembly 1 includes a power supply electrode 11. When the atomizer 21 is electrically connected to the power supply assembly 1, the power-taking electrode 212 of the atomizer 21 is electrically connected to the power supply electrode 11 of the power supply assembly 1. Specifically, the power supply electrode 11 includes a positive electrode and a negative electrode. When the power-taking electrode 212 of the atomizer 21 is electrically connected to the power supply electrode 11 of the power supply assembly 1, the positive and negative electrodes of the atomizer 21 respectively abut against the positive and negative electrodes of the power supply assembly 1. Thus, the electrical connection between the atomizer 21 and the power supply assembly 1 is disconnectable, facilitating the replacement of the atomizer 21 electrically connected to the power supply assembly 1.

[0072] In some embodiments, the number of power supply electrodes 11 is less than the number of atomizers 21, such that the power supply electrodes 11 cannot be electrically connected to all atomizers 21 in the atomization assembly 2 at the same time. Preferably, there is only one set of power supply electrodes 11, so the power supply assembly 1 can only be electrically connected to one atomizer 21 in the atomization assembly 2 at a time.

[0073] In one embodiment, referring to FIG3, the aerosol generating device further includes a power supply 7 and a controller. The two electrodes of the power supply 7 are electrically connected to the positive and negative electrodes of the power supply component 1, respectively. The controller controls the power output of the power supply 7, for example, controlling the power supply 7 to provide power to the power supply component 1, and thus to provide power to the atomizer 21 electrically connected to the power supply component 1, causing the atomizer 21 to atomize the liquid matrix and generate aerosol. The controller can also control other operations of the aerosol generating device, such as controlling the identification information of the atomizer 21 electrically connected to the power supply component 1 and adjusting the power output of the power supply 7 to the power supply component 1 based on the identification information, or controlling sensory cues such as lights, motors, and players in the aerosol generating device to generate sensory cues. The power supply 7 can include any suitable battery, such as a rechargeable battery, or a disposable battery.

[0074] In the embodiment shown in Figure 3, the power supply 7 and the circuit board carrying the controller are housed within the housing, with the power supply 7 positioned on one side of the atomizing component 2, thus arranged side-by-side with it. Of course, in other embodiments, the power supply can also be positioned on one side of the atomizing component, thus arranged longitudinally with it. Furthermore, referring to Figure 3, in other embodiments, the housing surrounding the power supply 7 and the housing 6 surrounding the atomizing component 2 may not be the same housing.

[0075] In one embodiment, referring to Figures 2 and 4, the aerosol generating device further includes a driving component 3. The driving component 3 includes an operating part 31 and a first toothed foot 33 linked to the operating part 31. The first toothed foot 33 is configured to move between a first position and a second position under the drive of the operating part 31. The power supply component 1 or the atomizing component 2 includes a first inclined surface 2211. During at least a portion of the stroke in which the first toothed foot 33 moves from the first position to the second position, the first toothed foot 33 abuts against the first inclined surface 2211 and slides along the first inclined surface 2211. The first inclined surface 2211 thus rotates so that the first toothed foot 33 can continue to move to the second position, causing the power supply component 1 or the atomizing component 2 with the first inclined surface 2211 to rotate. The power supply component 1 and the atomizing component 2 thus rotate relative to each other, realizing the switching of the atomizer 21 in the atomizing component 2 that is electrically connected to the power supply component 1.

[0076] In a first aspect of this application, the first inclined surface 2211 is a component of the atomizing component 2, such that during at least a portion of the travel of the first tooth 33 from the first position to the second position, the first tooth 33 drives the atomizing component 2 to rotate. Preferably, the power supply component 1 remains stationary during the rotation of the atomizing component 2. Of course, during the rotation of the atomizing component 2, the power supply component 1 may also rotate at a different speed or in a different direction than the atomizing component 2.

[0077] In a second aspect of this application, the first inclined surface is a component of the power supply assembly, such that during at least a portion of the travel of the first tooth from the first position to the second position, the first tooth drives the power supply assembly to rotate. Preferably, the atomizing assembly remains stationary during the rotation of the power supply assembly. Of course, the atomizing assembly may also rotate at a different speed or in a different direction than the power supply assembly during the rotation of the power supply assembly.

[0078] Since the second aspect has roughly the same principle and idea as the first aspect, the components, structures, shapes or materials that enable the relative rotation of the atomizing component and the power supply component in the first aspect can also be applied to the second aspect. This application will focus on the first aspect and only briefly describe the second aspect. The following is a detailed description of the first aspect.

[0079] In one embodiment, referring to Figures 2 and 3, the aerosol generating device further includes a reset component 4, which is used to reset the first tooth 33 from the second position to the first position, so that the operating part 31 can drive the first tooth 33 to move from the first position to the second position again, and the first tooth 33 can thus drive the atomizing component 2 to rotate again.

[0080] Specifically, the reset component 4 includes an actuator 41 that can move between a third position and a fourth position. The actuator 41 is linked to the first tooth 33, such that the first tooth 33 is reset to the first position during at least a portion of the travel of the actuator 41 as it moves from the fourth position to the third position.

[0081] The reset assembly 4 may further include an elastic element 42, one end of which is connected to the actuating element 41, and the other end is connected to the atomizing assembly 2 or the power supply assembly 1, or the other end is connected to other fixing components. Thus, the elastic element 42 can deform during the movement of the actuating element 41 between the third and fourth positions. The elastic element 42 provides elastic force to hold the actuating element 41 in the third position, and under the action of the elastic element 42, the actuating element 41 can automatically move from the fourth position to the third position, thereby enabling the first tooth 33 to automatically reset from the second position to the first position.

[0082] In one embodiment, during at least a portion of the travel of the actuator 41 from the fourth position to the third position, the actuator 41 can interfere with the atomizing component 2 and drive the atomizing component 2 to continue rotating in the original rotation direction. For example, during at least a portion of the travel of the first tooth 33 from the first position to the second position, the atomizing component 2 rotates clockwise by a first angle θ1. During at least a portion of the travel of the actuator 41 from the fourth position to the third position, the atomizing component 2 continues to rotate clockwise and rotates by a second angle θ2. Therefore, when the operation unit 31 completes one operation, the first tooth 33 moves from the first position to the second position, and then resets from the second position to the first position under the action of the actuator 41. During this process, the total angle θ of the clockwise rotation of the atomizing component 2 is the sum of the first angle θ1 and the second angle θ2. In other words, when the operation unit 31 completes one operation, the angle θ of the rotation of the atomizing component 2 relative to the power supply component 1 is the sum of the first angle θ1 and the second angle θ2.

[0083] By rotating the atomizing component 2 by a second angle θ2 during at least part of the stroke of the actuating member 41 from the fourth position to the third position, the first angle θ1 and the slope extension length of the first inclined surface 2211 can be reduced, which can shorten the stroke trajectory between the first position and the second position and is beneficial to the miniaturization of the aerosol generating device.

[0084] Based on this, as an example, θ = 360° / n, where n is the number of atomizers 21, so that when the operation unit 31 is operated once, the atomizers 21 in the atomizing assembly 2 that are electrically connected to the power supply assembly 1 can be changed. For example, when there are four atomizers 21 arranged in a ring, the phase angle between two adjacent atomizers 21 is 90°. Therefore, the atomizing assembly 2 needs to rotate N*90° relative to the power supply assembly 1 to change the atomizers 21 that are electrically connected to the power supply assembly 1, where N = 1, 2, or 3; and θ = 90°, so that when the operation unit 31 is operated once, the atomizers 21 in the atomizing assembly 2 that are electrically connected to the power supply assembly 1 can be changed.

[0085] Furthermore, the first angle θ1 can be greater than the second angle θ2, and of course, the first angle θ1 can also be less than or equal to the second angle θ2.

[0086] As an example, referring to Figures 2 and 5, the power supply component 1 or the atomizing component 2 further includes a second inclined surface 2212. The actuating member 41 is provided with a second tooth 43. During at least part of the stroke of the actuating member 41 from the fourth position to the third position, the second tooth 43 abuts against the second inclined surface 2212 and slides along the second inclined surface 2212. The second inclined surface 2212 thus rotates so that the second tooth 43 can continue to move to the third position, so that the power supply component 1 or the atomizing component 2 with the second inclined surface 2212 continues to rotate in the original rotation direction. Therefore, the power supply component 1 and the atomizing component 2 continue to rotate relative to each other in the original rotation direction, realizing the transformation of the atomizer 21 in the atomizing component 2 that is electrically connected to the power supply component 1.

[0087] In one embodiment, referring to Figures 4 and 5, the length of the first inclined plane 2211 is different from the length of the second inclined plane 2212. As an example, if the length of the second inclined plane 2212 is greater than the length of the first inclined plane 2211, the length of the trajectory along which the second tooth 43 slides on the second inclined plane 2212 can therefore be greater than the length of the trajectory along which the first tooth 33 slides on the first inclined plane 2211, and thus the first angle θ1 can be greater than the second angle θ2. Alternatively, if the length of the second inclined plane 2212 is less than the length of the first inclined plane 2211, the length of the trajectory along which the second tooth 43 slides on the second inclined plane 2212 can therefore be less than the length of the trajectory along which the first tooth 33 slides on the first inclined plane 2211, and thus the first angle θ1 can be less than the second angle θ2. Wherein, when the first inclined plane 2211 includes a single inclined surface, the inclined plane length of the first inclined plane 2211 refers to the track extension length of that single inclined surface in the first inclined plane 2211; when the first inclined plane 2211 includes multiple inclined surfaces, the inclined plane length of the first inclined plane 2211 refers to the track extension length of a single inclined surface in the first inclined plane 2211. Similarly, the inclined plane length of the second inclined plane 2212 is also like this.

[0088] In one embodiment, referring to Figures 4 and 5, the first inclined surface 2211 and the second inclined surface 2212 are offset in the direction of rotation of the atomizing component 2. Thus, after the first tooth 33 slides along the first inclined surface 2211 to rotate the atomizing component 2 by a preset angle, a second inclined surface 2212 can be aligned with the second tooth 43. Therefore, during at least part of the stroke of the actuator 41 moving from the fourth position to the third position, the second tooth 43 can abut against the second inclined surface 2212 and slide along the second inclined surface 2212, thereby driving the atomizing component 2 to rotate.

[0089] When the first tooth 33 abuts against the first inclined surface 2211, the second tooth 43 can be spaced apart from the second inclined surface 2212. This prevents the atomizing component 2 or the power supply component 1 with the first inclined surface 2211 from rotating when the first tooth 33 drives it to do so, and also prevents the elastic member 42 connected to the atomizing component 41 from twisting. Conversely, when the second tooth 43 abuts against the second inclined surface 2212, the first tooth 33 can be spaced apart from the first inclined surface 2211. This prevents the first tooth 33 from obstructing the rotation of the atomizing component 2 or the power supply component 1 with the second inclined surface 2212 when the second tooth 43 drives it to do so, and also prevents the operating part 31 connected to the first tooth 33 from rotating.

[0090] In one embodiment, referring to Figures 2, 3, and 8, the drive assembly 3 further includes a drive rod 32 connected to the operation unit 31. A first tooth 33 is disposed on the drive rod 32, and the drive rod 32 is connected to the actuator 41. Thus, during at least a portion of the stroke in which the first tooth 33 moves from the first position to the second position, the drive rod 32 pushes the actuator 41 from the third position to the fourth position. Therefore, the operation unit 31 can be used to move the actuator 41 from the third position to the fourth position, and during at least a portion of the stroke in which the actuator 41 moves from the fourth position to the third position, the actuator 41 can push the drive rod 32 to move the first tooth 33 from the second position to the first position, and the drive rod 32 can drive the operation unit 31 to reset.

[0091] Furthermore, during at least a portion of the travel of the first tooth 33 from the first position to the second position, the drive rod 32 drives the actuator 41 to gradually move away from the second inclined plane 2212. When the first tooth 33 is in the second position, the actuator 41 can be in the fourth position, such that the second tooth 43 is spaced apart from the second inclined plane 2212. During at least a portion of the travel of the actuator 41 from the fourth position to the third position, the actuator 41 drives the drive rod 32 to gradually move the first tooth 33 away from the first inclined plane 2211. When the second tooth 43 is in the third position, the first tooth 33 can be in the first position, such that the first tooth 33 is spaced apart from the first inclined plane 2211.

[0092] In the embodiments shown in Figures 8 and 9, a portion of the drive rod 32 is nested within the actuating member 41, and the drive rod 32 and the actuating member 41 are fixed together by a snap-fit ​​connection. Specifically, the drive rod 32 is provided with a latching protrusion 321, and the actuating member 41 is provided with a latching groove 411. When a portion of the drive rod 32 is nested within the actuating member 41, the latching protrusion 321 is snapped into the latching groove 411, thereby preventing the drive rod 32 and the actuating member 41 from separating.

[0093] In one embodiment, the atomizing component 2 further includes an interference portion 221, on which both the first inclined surface 2211 and the second inclined surface 2212 are formed. Therefore, during at least a portion of the travel from the first position to the second position, the first tooth 33 interferes with the interference portion 221 by sliding along the first inclined surface 2211. During at least a portion of the travel of the actuating member 41 from the fourth position to the third position, it interferes with the interference portion 221 by sliding along the second inclined surface 2212.

[0094] As an example, referring to Figures 4 and 5, the first tooth 33 and the second tooth 43 are located on opposite sides of the interference portion 221, and the first inclined surface 2211 and the second inclined surface 2212 are formed on opposite sides of the interference portion 221. In this example, the inclination directions of the first inclined surface 2211 and the second inclined surface 2212 are opposite, so that the rotation direction of the atomizing component 2 when the first tooth 33 slides along the first inclined surface 2211 is the same as the rotation direction of the atomizing component 2 when the second tooth 43 slides along the second inclined surface 2212.

[0095] As an example, referring to Figure 5, the interference portion 221 further includes a second stop surface 2214. The second stop surface 2214 abuts against the second tooth foot 43 located in the third position, preventing the second tooth foot 43 from continuing to move along the second inclined plane 2212 in the original direction and from undergoing further longitudinal positional changes when it moves to the third position. The second tooth foot 43 can be approximately wedge-shaped, and the shape formed by the combination of the second stop surface 2214 and the second inclined plane 2212 can also be wedge-shaped. When the second tooth foot 43 is in the third position, the two opposing surfaces on the second tooth foot 43 can be respectively positioned towards the second inclined plane 2212 and the second stop surface 2214. The second stop surface 2214 and the second inclined plane 2212 can have different slopes, with the slope of the second stop surface 2214 being greater than that of the second inclined plane 2212. The second stop surface 2214 can be approximately parallel to the longitudinal direction.

[0096] Furthermore, the second inclined surface 2212 includes multiple inclined surfaces, which are inclined in the same direction and distributed around each other. A second stop surface 2214 is provided between two adjacent inclined surfaces in the second inclined surface 2212. When the first tooth 33 is in the first position, the second tooth 43 corresponds to one of the inclined surfaces in the second inclined surface 2212 and abuts against the second stop surface 2214 that cooperates with the inclined surface. During at least a part of the stroke in which the first tooth 33 moves from the first position to the second position, the actuating member 41 disengages from the third position, and the atomizing component 2 rotates by a first angle θ1, so that the second tooth 43 corresponds to another adjacent inclined surface. During at least a part of the stroke in which the actuating member 41 moves from the fourth position to the third position, the second tooth 43 abuts against the other adjacent inclined surface and slides along the other adjacent inclined surface, so that the atomizing component 2 continues to rotate in the original rotation direction.

[0097] There may be only one second toothed foot 43, but preferably there are multiple second toothed feet 43. Multiple second toothed feet 43 can simultaneously abut against different inclined surfaces of the second inclined surface 2212 and can simultaneously slide along different inclined surfaces of the second inclined surface 2212.

[0098] When the second inclined surface 2212 includes multiple inclined surfaces that are inclined in the same direction and distributed around each other, the inclined surface corresponding to the second tooth 43 in the second inclined surface 2212 changes once every time the atomizing component 2 rotates by a first angle θ1.

[0099] When the second stop surface 2214 between two adjacent inclined surfaces of the second inclined surface 2212 abuts against the second tooth 43, the interference portion 221 locks the actuator 41, preventing the interference portion 221 and the actuator 41 from rotating relative to each other. Simultaneously, it prevents the atomizing assembly 2 and the power supply assembly 1 from rotating relative to each other. Therefore, this third position can also be called the locked position. When the second tooth 43 disengages from the second stop surface 2214, the locking of the interference portion 221 on the actuator 41 is released, allowing the interference portion 221 and the actuator 41 to rotate relative to each other. Therefore, under the interaction of the first tooth 33 and the interference portion 221, the atomizing assembly 2 with the interference portion 221 can rotate by a first angle θ1, causing the second tooth 43 to pass over the second stop surface 2214 and align with another adjacent second stop surface 2214. When the actuator 41 is in the fourth position, the actuator 41 and the second stop surface 2214 are spaced apart. Therefore, this fourth position can also be called the unlocked position.

[0100] Therefore, in some embodiments, driven by the operating unit 31, the actuator 41 moves from the locked position to the unlocked position. When the actuator 41 is in the locked position, it can interlock with the interference part 221, preventing the power supply component 1 or the atomizing component 2 with the interference part 221 from rotating relative to the actuator 41, and also preventing the power supply component 1 and the atomizing component 2 from rotating relative to each other. During at least a portion of the stroke of the actuator 41 moving from the unlocked position to the locked position, the actuator 4 can drive the power supply component 1 or the atomizing component 2 with the interference part 221 to rotate, causing the power supply component 1 and the atomizing component 2 to rotate relative to each other. In this embodiment, the operating unit 31 is mainly used to drive the actuator 41 from the locked position to the unlocked position to unlock it. During the process of the actuator 41 moving from the locked position to the unlocked position, it is preferable that the atomizing component 2 and the power supply component 1 can rotate relative to each other, but this relative rotation is optional rather than mandatory. In this embodiment, the elastic member 42 is used to automatically move the actuating member 41 from the unlocked position to the locked position, and the actuating member 41 interferes with the interference portion 221 under the drive of the elastic member 42, so that the atomizing component 2 or the power supply component 1 with the interference portion 221 rotates, and the atomizing component 2 and the power supply component 1 rotate relative to each other.

[0101] As an example, referring to Figure 4, the interference portion 221 further includes a first stop surface 2213. The first stop surface 2213 abuts against the first tooth 33 located in the second position, preventing the first tooth 33 from continuing to move along the first inclined surface 2211 and from undergoing further longitudinal positional changes when it moves to the second position. The first tooth 33 is approximately wedge-shaped, and the shape formed by the combination of the first stop surface 2213 and the first inclined surface 2211 can also be wedge-shaped. When the first tooth 33 is in the second position, the two opposing surfaces on the first tooth 33 can be respectively positioned towards the first inclined surface 2211 and the first stop surface 2213. The first stop surface 2213 and the first inclined surface 2211 can have approximately the same slope, and the first stop surface 2213 and the first inclined surface 2211 can be arranged axially symmetrically or surface symmetrically.

[0102] Furthermore, the first inclined surface 2211 may include a plurality of inclined surfaces that are inclined in the same direction and distributed around each other. A first stop surface 2213 is provided between two adjacent inclined surfaces in the first inclined surface 2211. When the second tooth 43 is in the third position, the first tooth 33 corresponds to one of the inclined surfaces in the first inclined surface 2211 and abuts against the first stop surface 2213 that cooperates with the inclined surface. During at least a part of the stroke in which the second tooth 43 moves from the fourth position to the third position, the first tooth 33 disengages from the second position, and the atomizing component 2 rotates by a second angle θ2, so that the first tooth 33 corresponds to another adjacent inclined surface. Thus, in the next operation of the operating unit 31, during at least a part of the stroke in which the first tooth 33 moves from the first position to the second position, the first tooth 33 abuts against the other adjacent inclined surface and slides along the other adjacent inclined surface, causing the atomizing component 2 to rotate.

[0103] The number of first toothed feet 33 can be exactly one, but preferably there are multiple first toothed feet 33. Multiple first toothed feet 33 can simultaneously abut against different inclined surfaces in the first inclined surface 2211 and can slide simultaneously along different inclined surfaces in the first inclined surface 2211. This allows the inclined surface in the first inclined surface 2211 corresponding to the first toothed foot 33 to change once for every second angle θ2 rotated by the atomizing component 2.

[0104] In one embodiment, referring to Figures 4 and 5, the aerosol generating device includes a support 22 for holding a plurality of the atomizers 21, and an interference portion 221 is a component of the support 22, so that at least one of the first tooth 33 and the actuating member 41 can drive the support 22 to rotate.

[0105] Furthermore, referring to Figures 2 and 4-6, the bracket 22 also includes a central tube 222, with multiple atomizers 21 arranged around the central tube 222, and the rotation axis of the atomizing component 2 coincides with the central axis of the central tube 222.

[0106] The actuator 41 is movably disposed inside the central tube 222. During at least a portion of the travel of the actuator 41 between the third and fourth positions, the actuator 41 can move inside the central tube 222 along the central axis of the central tube 222, and the central tube 222 can guide the movement of the actuator 41; and / or, the first tooth 33 is movably disposed inside the central tube 222. During at least a portion of the travel of the first tooth 33 between the first and second positions, the first tooth 33 can move inside the central tube 222 along the central axis of the central tube 222, and the central tube 222 can guide the movement of the first tooth 33.

[0107] In one embodiment, the central tube 222 extends longitudinally, the first position and the second position are offset longitudinally, the third position and the fourth position are offset longitudinally, the second position and the third position can be offset longitudinally, and the first position, the second position, the third position and the fourth position can be arranged sequentially along the longitudinal direction.

[0108] The actuator 41 can move helically between the third and fourth positions, preferably moving linearly along the longitudinal direction between the third and fourth positions. The first tooth 33 can move helically between the first and second positions, preferably moving linearly along the longitudinal direction between the first and second positions.

[0109] In one embodiment, referring to Figures 4 and 5, the interference portion 221 is disposed inside the central tube 222, so that both the second position and the third position are located in the central tube 222.

[0110] The support 22 may also include multiple partitions 223, which are radially connected to the central tube 222. A receiving space 224 exists between two adjacent partitions 223, and each receiving space 224 holds an atomizer 21. The support 22 may also include a bracket 225 for supporting the bottom of the atomizer 21, allowing the atomizer 21 to be held within its corresponding receiving space 224.

[0111] In the embodiment shown in Figure 2, the atomizing component 2 further includes a fixing member 23, which is at least partially disposed within the central tube 222 and can be snapped into the central tube 222, thereby allowing the fixing member 23 to remain relatively stationary with respect to the central tube 222 or the support 22. An elastic member 42 is connected to the fixing member 23, and an actuating member 41 is rotatably connected to the fixing member 23. Preferably, the elastic member 42 includes a spring, which can be spirally disposed around the actuating member 41. In the embodiment shown in Figure 2, the fixing member 23 is fixedly connected to the central tube 222 after the reset component 4 is assembled into the interior of the central tube 222.

[0112] In one embodiment, referring to Figures 1-3, the aerosol generating device further includes a mouthpiece assembly 5, independent of the drive assembly 3. The mouthpiece assembly 5 includes a mouthpiece 51, which a user can hold in their mouth to draw aerosol generated by the atomizer 21, which is in fluid communication with the mouthpiece assembly 5. The mouthpiece assembly 5 may be in fluid communication only with a portion of the atomizer 21 in the atomizing assembly 2; for example, the mouthpiece assembly 5 may be in fluid communication only with the atomizer 21 in the atomizing assembly 2 that is electrically connected to the power supply assembly 1. The atomizing assembly 2 is configured to rotate relative to the mouthpiece assembly 5 to change the atomizer 21 in fluid communication with the mouthpiece assembly 5 by rotating relative to the mouthpiece assembly 5.

[0113] Based on this, as an example, referring to Figure 2, the atomizing component 2 is rotatably disposed within the housing 6, and the mouthpiece assembly 5 is connected to the housing 6. When the driving component 3 and the reset component 4 drive the atomizing component 2 to rotate, the atomizing component 2 can rotate within the housing 6, while the mouthpiece assembly 5 and the power supply component 1 do not rotate relative to the housing 6. This allows the atomizing component 2 to rotate synchronously relative to the power supply component 1 and the mouthpiece assembly 5. Therefore, through a single operation of the operating unit 31, the atomizer 21 electrically connected to the power supply component 1 can be changed, and the atomizer 21 fluidly connected to the mouthpiece assembly 5 can also be changed. Furthermore, the atomizer 21 electrically connected to the power supply component 1 can simultaneously be fluidly connected to the mouthpiece assembly 5. In this example, there may be no connection between the power supply component 1 and the mouthpiece assembly 5.

[0114] Alternatively, as an example, the power supply component 1 and the mouthpiece component 5 are connected so that the power supply component 1 and the mouthpiece component 5 can remain synchronized in the direction of rotation of the atomizing component 2, so that when the driving component 3 and the reset component 4 drive the atomizing component 2 to rotate, the atomizing component 2 can rotate synchronously relative to the power supply component 1 and the mouthpiece component 5.

[0115] In the second case, the nozzle assembly 5 can be connected to the power supply assembly 1. When the drive assembly 3 and the reset assembly 4 drive the power supply assembly 1 to rotate, the power supply assembly 1 and the nozzle assembly 5 can rotate synchronously relative to the outer shell 6, or can rotate synchronously relative to the atomizing assembly 2.

[0116] It should be noted that in other embodiments, the mouthpiece is in fluid communication with all the atomizers in the atomizing assembly, and the mouthpiece assembly is connected to the atomizing assembly, so that the mouthpiece assembly and the atomizing assembly can move or remain stationary synchronously.

[0117] In one embodiment, at least a portion of the operating part 31 is exposed outside the housing 6 for user operation. The user can push the operating part 31 by pressing or sliding it, causing the operating part 31 to displace the first toothed foot 33 and the actuator 41 via the drive rod 32. In the embodiment shown in FIG. 2, the operating part 31 and the suction nozzle assembly 5 are located on opposite sides of the housing 6. In this embodiment, the user can push the operating part 31 by pressing it. Preferably, when the user presses the operating part 31, the operating part 31 can undergo longitudinal displacement or move linearly in the longitudinal direction, thereby reducing the longitudinal distance between the operating part 31 and the suction nozzle assembly 5. The first toothed foot 33 thus moves from a first position to a second position, and the actuator 41 can subsequently move from a third position to a fourth position. In other embodiments, at least a portion of the operating part 31 is exposed from the side wall of the housing 6 and can slide longitudinally relative to the housing 6. Therefore, when the user pushes the operating part 31 longitudinally, the longitudinal distance between the operating part 31 and the suction nozzle assembly 5 decreases.

[0118] It should be noted that the mouthpiece assembly and the drive assembly are independent and optional, not mandatory. For example, in one embodiment, the operating part includes a mouthpiece, which is in fluid communication with at least one atomizer in the atomizing assembly. Therefore, the user can push the mouthpiece to move the first tooth from a first position to a second position, causing the atomizing assembly or the power supply assembly to rotate, thereby changing the atomizer electrically connected to the power supply assembly by rotating the atomizing assembly and the power supply assembly relative to each other.

[0119] Furthermore, the power supply component and the atomizing component are arranged longitudinally, and the first tooth is configured to move longitudinally between a first position and a second position, thus enabling the first tooth to move linearly between the first and second positions. The power supply component is configured to move longitudinally relative to the atomizing component; for example, the power supply component is movably disposed within the housing and can move longitudinally within the housing, changing the longitudinal distance between the power supply component and the atomizing component. When the longitudinal distance between the power supply component and the atomizing component is large, the contact force between the power supply electrode and the atomizing component decreases, or there is no contact between the power supply electrode and the atomizing component. This reduces the frictional force borne by the power supply electrode when the atomizing component and the power supply component rotate relative to each other, which helps to reduce wear on the power supply electrode and prevent deformation of the power supply electrode.

[0120] Furthermore, the power supply component is linked to the mouthpiece or the drive rod. When the user pushes the mouthpiece, the first tooth moves longitudinally from the first position to the second position. Simultaneously, the longitudinal position of the power supply component changes, increasing the longitudinal distance between the power supply component and the atomizing component. As the power supply component changes position, the first tooth drives the atomizing component to rotate, thus pushing the mouthpiece. While the atomizing component and the power supply component rotate relative to each other, the longitudinal distance between them gradually increases. When the reset component resets the mouthpiece, the actuating element drives the atomizing component to continue rotating in the original direction, while the longitudinal distance between the atomizing component and the power supply component gradually decreases. When the actuating element returns to the third position, the mouthpiece resets, and the power supply electrode of the power supply component abuts against the corresponding power-taking electrode of the atomizer. Preferably, the power supply electrode of the power supply component and the corresponding power-taking electrode of the atomizer are in elastic contact.

[0121] In one embodiment, referring to Figures 2, 3, and 10, the first tooth 33 can drive the atomizing assembly 2 to rotate. The power supply assembly 1 includes a mounting base 12, a power supply electrode 11 disposed on the mounting base 12, and a through hole 13 opened on the mounting base 12. The power supply electrode 11 is detachably electrically connected to an atomizer 21 in the atomizing assembly 2. The inner wall of the through hole 13 includes an anti-rotation stop wall 131. A portion of the drive rod 32 interferes with the anti-rotation stop wall 131 in the through hole 13 to prevent the drive rod 32 from rotating relative to the power supply assembly 1 when the first tooth 33 moves between the first position and the second position, so that the first tooth 33 moves in a straight line between the first position and the second position.

[0122] Furthermore, the drive rod 32 has a protrusion 34, a portion of which is located in the through hole 13 and interferes with the anti-rotation stop wall 131. The end of the protrusion 34 forms a first tooth 33. When there are multiple first teeth 33, there are multiple protrusions 34. In the embodiment shown in Figures 7-10, there are four protrusions 34, and the through hole 13 is approximately a cross-shaped hole.

[0123] In the embodiment shown in FIG2, the power supply component 1 is disposed between the operation part 31 and the first tooth 33. In other embodiments, the operation part 31 may be located between the power supply component 1 and the first tooth 33.

[0124] In the embodiments shown in Figures 3 and 9, the power supply assembly 1 further includes an air hole 14 disposed on the mounting base 12, the air hole 14 being in fluid communication with the outside and an atomizer 21 electrically connected to the power supply electrode 11. The air hole 14 may be disposed between the two power supply electrodes 11.

[0125] In some embodiments, the user operates the operation part 31 of the drive component 3, causing one or more components of the drive component 3 (including the operation part 31) to move linearly from a first position to a second position. The reset component 4, based on its linkage with one or more components of the drive component 3, can drive one or more components of the drive component 3 that have deviated from their initial position in the linear direction to reset, for example, causing the operation part 31 and / or the first tooth 33 to return to the first position. During a user's operation of the operation part 31, i.e., during the process of one or more components of the drive component 3 moving linearly from the first position to the second position and then resetting along the reset stroke to the initial position, at least one of the drive component 3 and the reset component 4 can drive the atomizing component 2 to rotate relative to the power supply component 1. Here, linear movement refers to linear movement, and the linear direction is a straight line.

[0126] For example, the reset component 4 can cooperate with the atomizing component 2 during the reset stroke to drive the atomizing component 2 to rotate; when the operation unit 31 is in the first position, the first atomizer in the atomizing component 2 is electrically connected to the power supply electrode 11, so the first atomizer can atomize the liquid matrix to produce a mist when the power supply 7 provides power; when the operation unit 31 is moved from the first position to the second position by user operation and is driven by the reset component 4 to return to the first position, the reset component 4 can drive the atomizing component 2 to rotate by a predetermined angle, such as rotating by a second angle θ2, so that the second atomizer in the atomizing component 2, which is different from the first atomizer, corresponds to the position of the power supply electrode 11 and maintains electrical connection, so the second atomizer can atomize the liquid matrix to produce a mist when the power supply 7 provides power.

[0127] Preferably, when the user completes an operation on the operating unit, both the driving component 3 and the reset component 4 can drive the atomizing component 2 to rotate relative to the power supply component 1.

[0128] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
