Description

Technical Field

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

[0002] An aerosol-generating device is a device capable of atomizing an aerosol-generating formulation to form an aerosol. Some exemplary prior art examples include aerosol-generating devices comprising multiple, selectable atomizers. For example, a typical aerosol-generating device includes a power supply assembly and an atomizer assembly having multiple atomizers. By rotating the atomizer assembly relative to the power supply assembly, one of the atomizers in the atomizer assembly is electrically connected to an output electrode of the power supply assembly, thereby enabling the atomizer to be activated and generate aerosol when powered on.

[0003] There are multiple wave points on the power supply assembly and multiple grooves on the atomizer assembly. When the atomizer assembly and the power supply assembly rotate relative to each other until the wave points and the grooves are engaged, vibration or clicking sound will be generated to remind the user that an atomizer is electrically connected to the output electrode of the power supply assembly.

[0004] However, when the atomizer assembly and the power supply assembly are rotated relative to each other, the wave points will be worn, and after multiple rotations, the tactile feedback prompts generated when the wave points and the grooves are engaged will be reduced. As a result, during the relative rotation of the atomizer assembly and the power supply assembly, the user cannot clearly and accurately determine whether the atomizer is electrically connected to the output electrode.

[0051] Please refer to Figure 1-Figure 3 An embodiment of the present application provides an aerosol generating device 100, comprising a power supply component 1 and an atomizing component 2 having a plurality of atomizers 21, wherein the atomizing component 2 is configured to rotate relative to the power supply component 1 so as to select at least one of the plurality of atomizers 21 to be electrically connected to the power supply component 1 by rotation.

[0052] As used in this application, "plurality" refers to two or more. Figure 8 In the illustrated embodiment, the atomization assembly 2 includes four atomizers 21 , which are arranged in a ring shape.

[0053] At least two of the multiple atomizers 21 can be used to accommodate different liquid matrices. The different liquid matrices include solutions with different flavors or solutions with different ingredients and proportions. Of course, in some embodiments, all the atomizers 21 can accommodate the same liquid matrix.

[0054] Wherein, the liquid matrix can comprise the liquid containing tobacco substance that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco substance.The liquid matrix can comprise water, liquid medicine, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture etc., and spices can comprise betel nut extract, menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide various fragrance or local flavor to the user.The vitamin mixture can be the mixture that is mixed with at least one in vitamin A, vitamin B, vitamin C and vitamin E, but is not limited to this.Based on the different properties of liquid matrix, aerosol generating device can be used for different fields, such as, medical treatment, electronic aerosol atomization etc.

[0055] The nebulizer 21 includes a liquid cup 211 for holding a liquid matrix and an atomizing core 212 in fluid communication with the liquid cup 211. The atomizing core 212 is used to atomize the liquid matrix, producing an aerosol. In some embodiments, the atomizing core 212 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 directing the liquid matrix into the atomization range of the heating element. The heating element is used to atomize at least a portion of the liquid matrix on the liquid absorbing element to form an aerosol. The heating element may be integrated with the liquid absorbing element so that the heating element and the heating element form a single unit. In some embodiments, the liquid cup 211 includes a liquid reservoir 213, into which the liquid matrix is ​​absorbed and thereby retained within the liquid cup 211. Of course, the liquid reservoir 213 is optional and not required. In some embodiments, the atomizing core 212 may include an ultrasonic generating element, so that the atomizing core 212 can utilize ultrasonic waves to atomize the liquid matrix to form an aerosol.

[0056] At least a portion of the wall of the liquid cup 211 may be transparent, so that a user can observe the remaining amount of the liquid matrix inside the liquid cup 211 through the wall of the liquid cup 211 .

[0057] Each of the above-mentioned nebulizers 21 may further include an airway tube 214, which is in fluid communication with the atomizing core 212 and is used to transmit the aerosol. In one example, the nebulizer 21 may include an atomizing compartment in fluid communication with the liquid cup 211, with the atomizing core 112 housed in the atomizing compartment, and the airway tube 214 in fluid communication with the atomizing compartment; alternatively, in another example, at least a portion of the atomizing core 112 is disposed in the airway tube 214.

[0058] Each of the above-mentioned atomizers 21 may further include a power-taking electrode 215 , and the atomizing core 212 operates by drawing power from the power-taking electrode 215 . The power-taking electrode 215 may include a positive electrode and a negative electrode, and the positive electrode and the negative electrode may be electrically connected to opposite ends of the atomizing core, respectively.

[0059] The power supply assembly 1 includes an output electrode 11. When the atomizer 21 is electrically connected to the power supply assembly 1, the power extraction electrode 215 of the atomizer 21 is electrically connected to the output electrode 11 of the power supply assembly 1. Specifically, the output electrode 11 includes a positive electrode and a negative electrode. When the power extraction electrode 215 of the atomizer 21 is electrically connected to the output electrode 11 of the power supply assembly 1, the positive electrode and negative electrode of the atomizer 21 abut against the positive electrode and negative electrode of the power supply assembly 1, respectively. Thus, the electrical connection between the atomizer 21 and the power supply assembly 1 is disconnectable, thereby facilitating the replacement of the atomizer 21 electrically connected to the power supply assembly 1.

[0060] In some embodiments, the number of output electrodes 11 is less than the number of atomizers 21, so that the output electrodes 11 cannot be electrically connected to all atomizers 21 in the atomizer assembly 2 at the same time. Preferably, there is one and only one set of output electrodes 11, so that the power supply assembly 1 can only be electrically connected to one atomizer 21 in the atomizer assembly 2 at a time.

[0061] In one embodiment, reference may be made to Figure 2 The power supply component 1 also includes a power supply 13 and a circuit board 12. The two electrodes of the power supply 13 are electrically connected to the positive electrode and the negative electrode of the output electrode 11 respectively. The circuit board 12 may have a controller, which is used to control the power output of the power supply 13, for example, controlling the power supply 13 to provide power to the output electrode 11, and then providing power to the atomizer 21 electrically connected to the output electrode 11, so that the atomizer 21 atomizes the liquid matrix to produce an 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 13 to the output electrode 11 based on the identity information, or for example controlling the sensory prompters such as lights, motors, players, etc. in the aerosol generating device to generate sensory prompt signals. Among them, the power supply 13 can include any suitable battery, for example, it can include a rechargeable battery, and of course it can also include a disposable battery.

[0062] In some embodiments, reference may be made to Figure 1-Figure 3 The aerosol generating device further includes a drive assembly 3, which includes an operating portion 31 and a first movable member 32 interlocked with the operating portion 31. The operating portion 31 can be operated by a user, and the user can drive the first movable member 32 to rotate by operating the operating portion 31. The power supply assembly or the atomization assembly is interlocked with the operating portion 31, and the operating portion 31 drives one of the power supply assembly 1 and the atomization assembly 2 to rotate relative to each other, thereby selecting at least one of the multiple atomizers 21 to be electrically connected to the power supply assembly 1.

[0063] In some embodiments, the aerosol generating device 100 further includes a tactile feedback mechanism for providing tactile feedback to prompt the user that at least one of the plurality of atomizers 21 is electrically connected to the power supply assembly 1 .

[0064] More specifically, the tactile feedback mechanism includes a first movable member 31 and a second movable member 22. The first movable member 31 is arranged in linkage with the operating portion 31 and can rotate under the drive of the operating portion 31. The second movable member 22 is restricted from rotating. Among them, at least one of the first movable member 32 and the second movable member 22 has an abutment portion that can maintain contact with the other, and the abutment portion is configured to have undulations, so that when the first movable member 31 is driven to rotate by the operating portion 31, the second movable member 22 can move between the first position and the second position along with the undulations of the abutment portion. Preferably, the second movable member 22 can move linearly between the first position and the second position.

[0065] Since one of the first movable member 32 and the second movable member 22 maintains contact with the other through the abutment portion, the other can move along the undulating abutment portion when the first movable member 31 rotates. The other can move from the undulating valley to the undulating peak along the abutment portion. The other can move along the undulating peak to the undulating valley. The difference between the undulating valley and the undulating peak can be fed back to the user through the operating portion 31 to provide an obvious operating feel. Based on this, the tactile feedback mechanism prompts the user that at least one of the multiple atomizers 21 is electrically connected to the power supply component 1.

[0066] It should be noted that the abutting portion having undulations means that the abutting portion includes a non-circular and non-spherical abutting surface or a non-planar abutting surface, so that a part of the abutting surface of the abutting portion is obviously concave or obviously convex relative to the other part of the abutting surface.

[0067] The first movable member 32 is disposed during at least a portion of the relative rotational travel between the power supply assembly 1 and the atomizer assembly 2, and is capable of rotating relative to the second movable member 22. The undulating abutment creates torsional damping between the first movable member 32 and the second movable member 22, thereby providing drive damping and a variable operating feel for the operating portion 31. Based on this varying operating feel, the user can clearly and accurately determine whether the atomizer 21 is electrically connected to the power supply assembly 1.

[0068] In some embodiments, the operating portion 31 is linked to the first movable member 32 , so that the operating portion 31 can drive the first movable member 32 to rotate, or the first movable member 32 can rotate synchronously with the operating portion 31 , so that the first movable member 32 can rotate relative to the second movable member 22 .

[0069] In some embodiments, reference may be made to Figure 5 、 Figure 6 、 Figure 10-12 The abutment portion includes a plurality of first protrusions 321 arranged alternately on the first movable member 32. During at least part of the stroke in which the power supply assembly 1 and the atomizer assembly 2 rotate relative to each other, the second movable member 22 rotates relative to the first movable member 32, and at least a portion of the second movable member 22 moves along at least one first protrusion 321 from one side of the first protrusion 321 to the other side of the first protrusion 321.

[0070] The valley bottom of the abutting portion may include a portion located between two adjacent first protrusions 321 on the first movable member 32 , and this portion is referred to as a first valley bottom 222 .

[0071] As an example, when at least a portion of the second movable member 22 is located between two adjacent first protrusions 321, it can contact the two adjacent first protrusions 321 at the same time; in this example, during the rotation of the second movable member 22 relative to the first movable member 32, the second movable member 22 can always have no contact with at least one first valley bottom 222; of course, during the rotation of the second movable member 22 relative to the first movable member 32, the second movable member 22 can also contact each first valley bottom 222 simultaneously or sequentially.

[0072] As an example, when at least a portion of the second movable member 22 is located between two adjacent first protrusions 321 and simultaneously contacts the two adjacent first protrusions 321, the second movable member 22 is located in the first position, so that when the second movable member 22 is reset to the first position from the second position or from a position between the first position and the second position, it can provide the user with an obvious sense of pause or blockage.

[0073] As an example, when at least a portion of the second movable member 22 contacts the first valley bottom 222 , the second movable member 22 is located at the first position.

[0074] As an example, at least a portion of the second movable member 22 can slide downhill along the side wall of the first protrusion 321 for a distance, and then be abutted by the first valley bottom 222 adjacent to the side wall of the first protrusion 321 or by another first protrusion 321 opposite to the side wall of the first protrusion 321.

[0075] As an example, at least a portion of the second movable member 22 may slide uphill along the side wall of the first protrusion 321 for a distance and then contact the peak of the first protrusion 321 .

[0076] As an example, when at least a portion of the second movable member 22 contacts the peak of the first protrusion 321, the second movable member 22 is in the second position. A first protrusion 321 is located between two adjacent first valleys 222. Thus, as at least a portion of the second movable member 32 moves along at least one first protrusion 321 from one side of the first protrusion 321 to the other side of the first protrusion 321, the second movable member 32 may move from the first position to the second position, and then return from the second position to the first position.

[0077] As an example, the first movable member 32 is configured to be rotatable 360°. The plurality of first protrusions 321 on the first movable member 32 are evenly arranged along a circle, such that the angles between any two adjacent first protrusions 321 are substantially equal.

[0078] In some embodiments, reference may be made to Figure 5 、 Figure 6 and Figure 13 The abutment portion includes a plurality of second protrusions 221 arranged alternately on the second movable member 22. During at least part of the relative rotation of the power supply assembly 1 and the atomizer assembly 2, the first movable member 32 rotates relative to the second movable member 22, and at least a portion of the first movable member 32 moves along at least one second protrusion 221 from one side of the second protrusion 221 to the other side of the second protrusion 221.

[0079] The valley bottom of the abutting portion may include a portion located between two adjacent second protrusions 221 on the second movable member 22 , and this portion is referred to as a second valley bottom 322 .

[0080] As an example, when at least a portion of the first movable member 32 is located between two adjacent second protrusions 221, it can contact the two adjacent second protrusions 221 at the same time; in this example, during the rotation of the first movable member 32 relative to the second movable member 22, the first movable member 32 can always have no contact with at least one second valley bottom 322; of course, during the rotation of the first movable member 32 relative to the second movable member 22, the first movable member 32 can also contact each second valley bottom 322 simultaneously or sequentially.

[0081] As an example, when at least a portion of the first movable member 32 is located between two adjacent second protrusions 221 and simultaneously contacts the two adjacent second protrusions 221, the second movable member 22 is located in the first position, so that when the second movable member 22 is reset to the first position from the second position or from a position between the first position and the second position, it can provide the user with an obvious sense of pause or blockage.

[0082] As an example, when at least a portion of the first movable member 32 contacts the second valley bottom 322 , the second movable member 22 is located at the first position.

[0083] As an example, at least a portion of the first movable member 32 can slide downhill along the side wall of the second protrusion 221 for a distance, and then be abutted by the second valley bottom 322 adjacent to the side wall of the second protrusion 221 or by another second protrusion 221 opposite to the side wall of the second protrusion 221.

[0084] As an example, at least a portion of the first movable member 32 may slide uphill along the side wall of the second protrusion 221 for a certain distance and then contact the peak of the second protrusion 221 .

[0085] As an example, when at least a portion of the first movable member 32 contacts the peak of the second protrusion 221, the second movable member 22 is in the second position. A second protrusion 221 is located between two adjacent second valleys 322. Thus, as at least a portion of the first movable member 32 moves along at least one second protrusion 221 from one side of the second protrusion 221 to the other side of the second protrusion 221, the second movable member 32 may move from the first position to the second position, and then return from the second position to the first position.

[0086] As an example, the first movable member 32 is configured to be rotatable 360°. The plurality of second protrusions 221 on the second movable member 22 are evenly arranged along a circle, such that the angles between any two adjacent second protrusions 221 are substantially equal.

[0087] In some embodiments, reference may be made to Figure 10-13 The first movable member 32 and the second movable member 22 are non-coaxially arranged. The movement trajectory of the second movable member 22 between the first position and the second position may intersect the central axis 2X of the first movable member 32; for example, the movement trajectory of the second movable member 22 between the first position and the second position may be approximately perpendicular to the central axis 2X of the first movable member 32. The central axis 1X of the second movable member 22 may intersect the central axis 2X of the first movable member 32; for example, the central axis 1X of the second movable member 22 may be approximately perpendicular to the central axis 2X of the first movable member 32.

[0088] In some embodiments, reference may be made to Figure 5 and Figure 6 The first movable member 32 and the second movable member 22 are coaxially arranged. The central axis of the first movable member 32 can be arranged collinearly with the central axis of the second movable member 22. Alternatively, the first movable member 32 can rotate about the central axis of the second movable member 22. Alternatively, the central axis of the first movable member 32 can be arranged collinearly with the central axis of the movement trajectory of the second movable member 22 between the first position and the second position.

[0089] Furthermore, the first movable member 32 includes a plurality of first protrusions 321, and / or the second movable member 22 includes a plurality of second protrusions 221, so that when the first movable member 32 rotates, the first movable member 32 can switch between an engaged state and a non-engaged state with the second movable member 22. For example, at least one of the first movable member 32 and the second movable member 22 can be a gear structure. For example, one of the first movable member 32 and the second movable member 22 is a gear and the other is a rack. In the example Figure 5 and Figure 6 In the illustrated embodiment, the first movable member 32 and the second movable member 22 are both face gear structures.

[0090] In some embodiments, when the first movable member 32 is engaged with the second movable member 22, the second movable member 32 is located at the first position. When the first movable member 32 is not engaged with the second movable member 22, the second movable member 32 is located at the second position.

[0091] When the first movable member 32 and the second movable member 22 are in meshing state, the first protrusion 321 may abut against the second valley bottom 222 , or the first protrusion 321 may be located between two adjacent second protrusions 221 and contact the two second protrusions 221 at the same time.

[0092] Alternatively, when the first movable member 32 and the second movable member 22 are in engagement, the second protrusion 221 may abut against the first valley 322 , or the second protrusion 221 may be located between two adjacent first protrusions 321 and contact the two first protrusions 321 simultaneously.

[0093] When the first movable member 32 and the second movable member 22 are in a non-engaged state, the peak of the first protrusion 321 may abut against the peak of the second protrusion 221 .

[0094] It should be noted that the first valley bottom 322 may be a non-planar surface, a line, or a point. The second valley bottom 222 may be a non-planar surface, a line, or a point. The peak of the first raised portion 321 may be a non-planar surface, a partially planar surface, a line, or a point. The peak of the second raised portion 221 may be a non-planar surface, a partially planar surface, a line, or a point.

[0095] In some embodiments, the tactile feedback mechanism further includes an elastic member 23, which is configured to provide elastic force to the second movable member 22, thereby maintaining the second movable member 22 in the first position. Alternatively, the elastic member 23 is configured to provide torsional damping during the movement of the second movable member 22 from the first position to the second position. The elastic member 23 helps promote the automatic return of the second movable member 22 to the first position.

[0096] The elastic member 223 may be located on a side of the second movable member 22 facing away from the first movable member 32 .

[0097] When the first movable member 32 is driven by the operating portion 31 and the first movable member 32 rotates around the central axis or the rotation shaft of the first movable member 32 , the elastic member 223 can elastically extend or contract on the central axis of the first movable member 32 .

[0098] For example, the user operates the operating portion 31 to drive the first movable member 32 to rotate, so that the first protrusion 321 slides uphill along the side wall of the second protrusion 221, or the second protrusion 221 slides uphill along the side wall of the first protrusion 321, so that the first movable member 32 and the second movable member 22 gradually change from a mutually engaged state to a non-engaged state. During this process, the second movable member 22 is restricted from rotating, so that the second movable member 22 moves along the central axis of the first movable member 32 in a direction away from the first movable member 32, and the elastic member 23 is then in the first movable member 32. Elastic contraction occurs on the central axis of the movable member 32, causing the drive damping to gradually increase. When the first movable member 32 and the second movable member 22 are in a non-engaged state, the drive damping reaches its maximum. When the first movable member 32 is further driven to rotate, the first protrusion 321 slides downhill along the side wall of the second protrusion 221, or the second protrusion 221 slides downhill along the side wall of the first protrusion 321, releasing the elastic potential energy of the elastic member 23. The elastic restoring force of the elastic member 23 can cause the first movable member 32 and the second movable member 22 to transform from a non-engaged state to an engaged state. When the first movable member 32 and the second movable member 22 are in an engaged state, the second movable member 22 is located in the first position, and the first movable member 32 and the second movable member 22 can be interlocked.

[0099] When the first movable member 32 and the second movable member 22 are in a non-engaged state, the elastic member 23 may be in an elastically compressed state.

[0100] When the first movable member 32 and the second movable member 22 are in the meshing state, the elastic member 23 can still be in the elastically compressed state. Of course, it can also be in the naturally extended state.

[0101] The second protrusion 221 may have two side walls disposed opposite to each other, and the first movable member 32 may slide uphill along one of the two side walls and slide downhill along the other side wall. The two side walls may have substantially equal inclinations and lengths.

[0102] The first protrusion 321 may have two side walls disposed opposite to each other, and the second movable member 22 may slide uphill along one of the two side walls and slide downhill along the other side wall. The two side walls may have substantially equal inclinations and lengths.

[0103] In some embodiments, the second movable member 22 is configured to be disposed on one of the power supply assembly 1 and the atomizer assembly 2 and to be rotatable relative to the other. Thus, in at least a portion of the stroke in which the power supply assembly 1 and the atomizer assembly 2 rotate relative to each other, the second movable member 22 can cause one of the power supply assembly 1 and the atomizer assembly 2 to rotate synchronously. Furthermore, when the second movable member 22 rotates relative to the first movable member 32, the second movable member 22 can interfere with the first movable member 32 in the lateral direction. The lateral interference fit between the second movable member 22 and the first movable member 32 can provide drive damping for the operating portion 31. The lateral direction is a direction perpendicular to the longitudinal direction, and movement occurring in a plane perpendicular to the longitudinal direction can also be referred to as movement occurring in the lateral direction.

[0104] In some embodiments, the aerosol generating device further comprises a mouthpiece assembly 4, at least a portion of which can be held between the lips of a user, and the user can inhale the aerosol / aerosol mist generated by the atomizing assembly 4 by inhaling the mouthpiece assembly 4. Therefore, during use of the aerosol generating device, the mouthpiece assembly 4 needs to be in fluid communication with at least one atomizer 21 in the atomizing assembly 2, so that the aerosol / aerosol mist in the airway tube 214 of the at least one atomizer 21 in the atomizing assembly 2 can be inhaled into the user's oral cavity through the inhalation port of the mouthpiece assembly 4.

[0105] In some embodiments, not all atomizers 21 of the atomizer assembly 2 can be in fluid communication with the mouthpiece assembly 4 at the same time. Only some of the atomizers 21 can be in fluid communication with the air inlet of the mouthpiece assembly 4 at the same time. Preferably, only one atomizer 21 can be in fluid communication with the air inlet of the mouthpiece assembly 4 at the same time. Therefore, after replacing the atomizer 21 electrically connected to the power supply assembly 1, it is necessary to also ensure that the atomizer 21 electrically connected to the power supply assembly 1 is in fluid communication with the mouthpiece assembly 4.

[0106] Based on this, in some embodiments, the operating portion 31 is configured to drive the suction nozzle assembly 4 and the atomizer assembly 2 to rotate relative to each other, so as to change the atomizer 21 in fluid communication with the suction nozzle assembly 4 .

[0107] In some embodiments, reference may be made to Figure 3The operating portion 31 is configured to be linked to both the power supply assembly 1 and the nozzle assembly 4, so that while the operating portion 31 drives the power supply assembly 1 to rotate relative to the atomizer assembly 2 to change the atomizer 21 electrically connected to the power supply assembly 1, it also drives the nozzle assembly 4 to rotate relative to the atomizer assembly 2 to change the atomizer 21 in fluid communication with the nozzle assembly 4. In other words, the user can perform an operation on the operating portion 31 to cause the nozzle assembly 4 and the power supply assembly 1 to rotate relative to the atomizer assembly 2 at the same time, thereby changing the atomizer 21 electrically connected to the power supply assembly 1 while also causing the atomizer 21 electrically connected to the power supply assembly 1 to be in fluid communication with the nozzle assembly 4. In this embodiment, the nozzle assembly 4 can rotate simultaneously with the power supply assembly 1; alternatively, the nozzle assembly 4 can remain relatively stationary with the power supply assembly 1.

[0108] In some embodiments, reference may be made to Figure 2 and Figure 3 The atomizer assembly 2 is located between the operating portion 31 and the suction nozzle assembly 4, thereby preventing the user from touching the suction nozzle assembly 4 during operation, which helps to keep the suction nozzle assembly 4 clean and hygienic.

[0109] You can refer to Figure 3 and Figure 9 The atomizer assembly 2 includes a central tube 241, and a plurality of atomizers 21 are distributed around the periphery of the central tube 241. The drive assembly 3 also includes a drive rod 33 that is linked to the operating portion 31. The drive rod 33 rotatably passes through the central tube 241 and is connected to the nozzle assembly 4.

[0110] Driven by the operating unit 31, the driving rod 33 can drive the nozzle assembly 4 to rotate relative to the atomizer assembly 2. The central axis of the atomizer assembly 2 can be collinear with the central axis of the central tube 241. Multiple atomizers 21 can be evenly arranged around the periphery of the central tube 241. Alternatively, at least two atomizers 21 can be arranged symmetrically with the central axis of the central tube 241 as the axis of symmetry.

[0111] In some embodiments, reference may be made to Figure 8 and Figure 9The atomizer assembly 2 also includes a bracket 24 having a bottom frame 242 and a partition plate 243. There may be multiple partition plates 243, and the multiple partition plates 243 provide multiple accommodation spaces in the bracket 24, each of which can accommodate an atomizer 21. Two adjacent atomizers 21 may be separated by a partition plate 243. The bottom frame 242 is used to support multiple atomizers 21, so that the multiple atomizers 21 can be kept in the corresponding accommodation spaces. The bottom frame 242 may have a through hole 2421, or the bottom frame 242 may have multiple through holes 2421 corresponding to the multiple atomizers 21. The power-taking electrode 215 on the atomizer 21 can be exposed through the through hole 2421, so that during the relative rotation of the atomizer assembly 2 and the power supply assembly 1, the output electrode 11 of the power supply assembly 1 can abut against and separate from the power-taking electrode 215 on the atomizer 21.

[0112] The central tube 241 may be a component of the bracket 24. A plurality of partition plates 243 may be radially connected to the outer wall of the central tube 241. The central tube 241 may be integrally injection molded with the partition plates 243 and the bottom frame 242. The longitudinal length of the central tube 241 may be greater than the longitudinal length of the partition plates 243. The central tube 241 may include a first portion and a second portion that are coaxial with each other, the first portion and the second portion being located on opposite sides of the bottom frame 242, and the first portion may be disposed closer to the nozzle assembly 4. The drive rod 33 may rotatably pass through the second portion and the first portion in sequence, and then be connected to the nozzle assembly 4.

[0113] When the driving rod 33 rotates inside the central tube 241 , the driving rod 33 rotates relative to the central tube 241 and the bracket 24 , and also rotates relative to the plurality of atomizers 21 .

[0114] In some embodiments, the second movable member 22 is fixedly connected to the central tube 241 or the bracket 24, and the first movable member 32 is connected to the operating portion 31 or to the power supply assembly 1, so that the operating portion 31 can drive the first movable member 32 and the power supply assembly 1 to rotate relative to the atomizer assembly 2 at the same time. Based on this, the atomizer assembly 2 or the power supply assembly 1 is configured to be movable in the longitudinal direction, so that when the first movable member 32 moves along the side wall of the second protrusion 221 of the second movable member 22, or when the second movable member 22 moves along the side wall of the first protrusion 321 of the first movable member 32, the atomizer assembly 2 moves longitudinally in a direction away from the power supply assembly 1, so that the distance between the atomizer assembly 2 and the power supply assembly 1 gradually increases, thereby preventing the output electrode 11 from being worn during at least part of the process of the atomizer assembly 2 rotating relative to the power supply assembly 1. In this embodiment, the second movable member 32 can be integrally injection molded with the bracket 24.

[0115] In some embodiments, reference may be made to Figure 3The center tube 241 has a cavity 2411 inside, and the second movable member 22 is non-rotatably disposed in the cavity 2411, while the driving rod 33 rotatably passes through the second movable member 22. Specifically, the second movable member 22 and the center tube 241 are independently formed.

[0116] There are many ways to prevent the second moving member 22 from rotating in the cavity 2411 of the central tube 241. For example, Figure 5 and Figure 8 , the cross sections of the second movable member 22 and the accommodating cavity 2411 can be non-circular.

[0117] Furthermore, the second movable member 22 can be configured to move longitudinally within the cavity 2411. The elastic member 23 can be located within the central tube 241 and can be disposed on a side of the second movable member 22 facing away from the first movable member 32. Thus, the elastic member 23 can elastically deform longitudinally within the central tube 241. When the first movable member 32 moves along the sidewall of the second protrusion 221 of the second movable member 22, or when the second movable member 22 moves along the sidewall of the first protrusion 321 of the first movable member 32, the second movable member 22 can move longitudinally within the cavity 2411.

[0118] The elastic member 23 may include a spring, for example, a coil spring, and the driving rod 33 may rotatably pass through the coil spring. The elastic member 23 may be made of silicone.

[0119] The center tube 241 may have an abutment portion 2412 therein, one end of the elastic member 23 abuts the abutment portion 2412 and the other end abuts the second movable member 22 or is connected to the second movable member 22. The cavity 2411 may be located in the second portion of the center tube 241.

[0120] In some embodiments, reference may be made to Figure 3 and Figure 5 The driving assembly 3 also includes a laterally extending support portion 34 , the driving rod 33 is arranged perpendicular to the support portion 34 and connected to the support portion 34 , the first movable member 32 is non-rotatably connected to the support portion 34 , and the first movable member 32 is arranged around the driving rod 33 .

[0121] The driving rod 33 and the supporting portion 34 can be integrally injection molded. Figure 5-Figure 7 In the illustrated embodiment, the first movable member 32 has at least one boss 323, and the support portion 34 is provided with a mounting hole 341. The boss 323 is engaged with the mounting hole 341, thereby preventing the first movable member 32 from rotating relative to the support portion 34 and, consequently, the first movable member 32 from rotating relative to the drive rod 33. In other embodiments, the first movable member 32 and the support portion 34 may be integrally injection molded.

[0122] In some embodiments, reference may be made to Figure 3 The drive assembly 3 further includes a first housing 35, and the atomizer assembly 2 further includes a second housing 25. The first housing 35 is rotatably connected to the second housing 25. The operating portion 31 is disposed on the first housing 35 and exposed outside the second housing 25. The plurality of atomizers 21 are disposed within the second housing 25. Thus, a user can operate the operating portion 31 to drive the first housing 35 to rotate relative to the second housing 25. The method for operating the operating portion 31 can be to drive the operating portion 31 to rotate.

[0123] In one embodiment, at least a portion of the second housing 25 has a viewing window, which includes a lens or a through-hole, so that the liquid cup 211 can be observed through the viewing window. When the wall of the liquid cup 211 is at least partially transparent, the remaining amount of liquid matrix in the liquid cup 211 can be observed sequentially through the second housing 25 and the liquid cup 211. There can be one or more viewing windows.

[0124] In some embodiments, the support portion 34 is located within the first housing 35 and divides the space inside the first housing 35 into a first receiving compartment and a second receiving compartment, wherein the first movable member 32 is located in the second receiving compartment. At least a portion of the power supply 13 can be received in the first receiving compartment.

[0125] In some embodiments, reference may be made to Figure 2 and Figure 3 The output electrode 11 is electrically connected to the circuit board 12, and the power supply 13 is electrically connected to the circuit board 12. The circuit board 12 can be fixed to the first housing 35. For example, the circuit board 12 can be located inside the first housing 35, or the end of the first housing 35 can support the circuit board 12. This allows the second storage compartment to be located between the circuit board 12 and the support portion 34. Based on this, the second portion of the central tube 241 can rotatably pass through the circuit board 12. Furthermore, the output electrode 11 can be fixed to the circuit board 12.

[0126] In some embodiments, reference may be made to Figure 3 and Figure 4 The power supply component 1 also includes an airflow detector 14 fixed on the circuit board 12 for detecting suction. When it is detected that the airflow change caused by the user's suction exceeds a threshold, the airflow detector 14 can supply power to the output electrode 11 through the power supply 13, so that the atomizer 21 electrically connected to the output electrode 11 can obtain power to atomize the liquid matrix.

[0127] It should be noted that, in other embodiments, the second movable member 22 is independently provided with the atomizer assembly 2, so that when the user actuates the operating portion 31, the second movable member 22 can move independently with the atomizer assembly 2. In other embodiments, the second movable member 22 is independently provided with the power supply assembly 1, so that when the user actuates the operating portion 31, the second movable member 22 can move independently with the power supply assembly 1.

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