[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese application entitled “Aerosol Generating Device” filed with the China National Intellectual Property Administration on February 2, 2024, with application number 202410163320.2, the entire contents of which are incorporated herein by reference. Technical Field

[0004] An aerosol-generating device is a device that atomizes a liquid formulation to form an aerosol. In some exemplary prior art, the aerosol-generating device includes a mouthpiece, an atomizer assembly, and a power supply assembly. The mouthpiece is connected to the atomizer assembly, and an electrode of the power supply assembly abuts the atomizer assembly. The atomizer assembly includes multiple atomizers. The atomizer assembly is rotated relative to the power supply assembly to sequentially position the multiple atomizers relative to the electrode. When the atomizers are relative to the electrode, the atomizers are electrically connected to the power supply assembly.

[0057] 1-12 , an embodiment of the present application provides an aerosol generating device, which includes a power supply component 3 and an atomization component 2 .

[0058] The atomizer assembly 2 includes multiple independent atomizers 21, each configured to operate independently when powered. The atomizer 21 includes a main body, which may include a storage chamber 211 capable of accommodating a liquid matrix. The amount of liquid matrix stored in each atomizer 21 may not exceed 5 ml, for example, approximately 2 ml. The liquid matrix may include a liquid containing a tobacco substance containing volatile tobacco flavor components, or a liquid containing a non-tobacco substance. The liquid matrix may include water, a medicinal solution, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture. Flavoring agents may include, but are not limited to, betel nut extract, menthol, peppermint, spearmint oil, and various fruit-flavored ingredients. Flavoring agents may include ingredients that provide a variety of aromas or flavors to the user. The vitamin mixture may include, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. Based on the different properties of the liquid matrix, the aerosol generating device can be used in different fields, such as medical treatment and electronic aerosol generation.

[0059] The term "plurality" refers to two or more. In the embodiment shown in Figures 2 and 3, there are five atomizers 21, but this is not limiting. At least two of the multiple atomizers 21 can be used to contain different liquid matrices. These different liquid matrices may include liquid matrices with different flavors or ingredients or ratios. This allows users to experience different sensory experiences by switching between atomizers 21. Of course, in one embodiment, all atomizers 21 can contain the same liquid matrices.

[0060] 4 to 6 , a liquid storage sponge 212 may be provided in the storage chamber 211 to retain at least a portion of the liquid matrix in the liquid storage sponge 212 . The provision of the liquid storage sponge 212 prevents leakage of the liquid matrix. The liquid storage sponge 212 is optional but not mandatory.

[0061] Referring to Figure 9, each atomizer 21 may also include an atomizer core 213. The atomizer core 213 is in fluid communication with the storage chamber 211 or connected to the liquid storage cotton 212. The atomizer core 213 is used to atomize the liquid matrix to generate an aerosol. The atomizer core 213 may include a liquid absorbing element and a heating element. The liquid absorbing element may be a porous body or fiber. The liquid absorbing element is capable of absorbing the liquid matrix and can guide the liquid matrix into the atomization range of the heating element; the heating element is used to atomize at least part of the liquid matrix on the liquid absorbing element to form an aerosol. The heating element can be combined with the liquid absorbing element so that the heating element and the liquid absorbing element form a whole.

[0062] Each atomizer 21 may also include a power supply assembly 214 electrically connected to the atomizer core 213 in the atomizer 21. Specifically, the power supply assembly 214 is connected to the heating element to conduct current. The power supply assembly 214 is electrically connected to the power supply assembly 3. The atomizer core 213 obtains power from the power supply assembly 3 through the power supply assembly 214, and then atomizes the liquid matrix to produce an aerosol.

[0063] The power collection component 214 may include a first power collection electrode 2141 and a second power collection electrode 2142. The first power collection electrode 2141 and the second power collection electrode 2142 can be a positive electrode and a negative electrode respectively, which can be electrically connected to the opposite ends of the heating element respectively, and can be electrically connected to the positive and negative electrodes of the power supply 51 respectively through the power supply component 3.

[0064] Each atomizer 21 may further include a retaining seat 217, which engages with the power extraction assembly 214 and is used to retain or support the power extraction assembly 214. The retaining seat 217 may be connected to the end of the main body. The power extraction assembly 214 may pass through the retaining seat 217. The retaining seat 217 includes a first surface 2171 disposed toward the power supply assembly 3.

[0065] Each atomizer 21 may further include an air inlet 216 fluidly connected to the atomizer core 213 . Air enters the interior of the atomizer 21 through the air inlet 216 and then flows toward the atomizer core 213 .

[0066] Each atomizer 21 may further include an air supply channel and an air outlet 215 . The air supply channel fluid connects the atomizing core 213 and the air outlet 215 . The aerosol generated by atomization by the atomizing core 213 is guided to the air outlet 215 via the air supply channel, and then enters the mouthpiece 1 through the air outlet 215 . The storage chamber 211 may be arranged around the air supply channel, or the air supply channel may be arranged on one side of the storage chamber 211 .

[0067] In one example, the atomizer 21 may have an atomizing compartment in fluid communication with the storage chamber 211 , the atomizing core 213 is accommodated in the atomizing compartment, the air supply channel is in fluid communication with the atomizing compartment, and the storage chamber 211 is located between the air outlet 215 and the atomizing compartment.

[0068] Alternatively, in another example, referring to Figure 9, at least a portion of the atomizer core 213 is arranged in the air supply channel, and a liquid guide hole is provided on the air supply channel. The atomizer core 213 is fluidically connected to the storage chamber 211 or connected to the liquid storage cotton 212 through the liquid guide hole. The liquid matrix in the storage chamber 211 or the liquid storage cotton 212 can pass through the liquid guide hole to be absorbed by the liquid absorption element and atomized by the heating element, or a portion of the liquid absorption element can pass through the liquid guide hole into the storage chamber 211 to absorb and conduct the liquid matrix.

[0069] In one embodiment, the plurality of atomizers 21 are distributed in the transverse direction. For example, the plurality of atomizers 21 can be arranged in a straight line in the transverse direction. For example, referring to Figures 2 and 3 , the plurality of atomizers 21 can be arranged in an array in the transverse direction, or in the same annular shape in the transverse direction.

[0070] In one embodiment, referring to FIG. 7 and FIG. 10 , the atomization assembly 2 further includes a holder 22 , and the holder 22 is used to hold a plurality of atomizers 21 .

[0071] Specifically, the holder 22 may include one or more partition plates 221. The one or more partition plates 221 allow the multiple atomizers 21 to be spaced apart from each other. Two adjacent atomizers 21 may be separated by at least one partition plate 221. A holding space 222 may be defined between two adjacent partition plates 221. Each holding space 222 may accommodate at least a portion of an atomizer 21.

[0072] The holder 22 may include a lifting portion 224, which may extend laterally to support the atomizer 21 so that the corresponding atomizer 21 can be retained in the corresponding retaining space 222. The lifting portion 224 may support the corresponding atomizer 21 by abutting at least a portion of the first surface 2171 of the retaining seat 217.

[0073] In the embodiment shown in Figures 11 and 12, the holder 22 includes a central column 225, the supporting portion 224 includes a supporting frame 2241, and a plurality of partition plates 221 are radially distributed between the central column 225 and the supporting frame 2241. The supporting frame 2241 can simultaneously support the ends of the plurality of partition plates 221. When the atomizer 21 is accommodated in the corresponding holding space 222, at least a portion of the first surface 2171 of the atomizer 21 is supported by the supporting frame 2241.

[0074] A retaining wall 223 is provided on the side of the partition plate 221 opposite the central column 225. The retaining wall 223 defines at least a portion of the outer boundary of the holding space 222. The retaining wall 223 is used to stop the atomizer 21 and prevent it from laterally separating from the holder 22. Referring to Figures 3, 11, and 12, adjacent retaining walls 223 are spaced apart from each other, and at least a portion of the retaining wall 223 is embedded between adjacent atomizers 21. This not only helps reduce material consumption and costs in manufacturing the holder 22, but also helps reduce the size of the aerosol generating device, enabling the aerosol generating device to meet the development demand for miniaturization.

[0075] In the embodiment shown in Figures 11 and 12, the lifting portion 224 includes a lifting plate 2242, which can simultaneously support the ends of multiple partition plates 221. The lifting plate 2242 extends in the transverse direction and can simultaneously support at least a portion of the first surface 2171 of multiple atomizers 21. The central column 225 extends in the longitudinal direction, and one end of the central column 225 is connected to the lifting plate 2242.

[0076] The lifting plate 2242 and the lifting frame 2241 are spaced apart from each other. Under the action of multiple partition plates 221, the space between the lifting plate 2242 and the lifting frame 2241 is divided into multiple positioning spaces. The bosses 2172 of the retaining seats 217 of multiple atomizers 21 are fixed in the positioning spaces one by one, and the power collection component 214 of the atomizer 21 is exposed through the open positioning space, so that the power collection component 214 can contact and separate from the power supply component 3.

[0077] The lifting portion 224, the partition plate 221 and the central column 225 can be integrally injection molded. It should be noted that it is optional for the lifting portion 224 to include both the lifting frame 2241 and the lifting plate 2242. In other embodiments, the lifting portion 224 includes either the lifting plate 2242 or the lifting frame 2241.

[0078] The power supply assembly 3 includes a first power supply electrode 31 and a second power supply electrode 32. The first power supply electrode 31 and the second power supply electrode 32 can be a positive electrode and a negative electrode, respectively, and can be electrically connected to the positive and negative electrodes of a power source. When the power supply assembly 3 corresponds to an atomizer 21, the first power supply electrode 31 and the second power supply electrode 32 can contact the first power extraction electrode 2141 and the second power extraction electrode 2142, respectively. The power supply assembly 3 is configured to selectively direct current to at least one of the multiple atomizers 21.

[0079] The contact between the power supply component 3 and the power extraction component 214 can be elastic to increase the stability of the contact between the power supply component 3 and the power extraction component 214. In one embodiment, the power supply component 3 is elastic, for example, the first power supply electrode 31 and / or the second power supply electrode 32 are elastic pins, or the first power supply electrode 31 and / or the second power supply electrode 32 include elastic sheets, which are used to elastically abut the power extraction component 214.

[0080] In one embodiment, the aerosol generating device includes a shell 6, the interior of the shell 6 has a chamber, and the atomization assembly 2 is at least partially accommodated in the chamber. Naturally, the holding space 222 is also at least partially located in the chamber. At least part of the inner wall of the shell 6 can define a partial boundary of the holding space 222, and the side wall of the atomizer 21 can contact the inner wall of the shell 6.

[0081] At least a portion of the power supply component 3 can be staggered with respect to the cavity and accommodated inside the housing 6 . Of course, in other embodiments, at least a portion of the power supply component 3 can also be located in the cavity.

[0082] At least a portion of the sidewall of the main body of the atomizer 21 may be transparent, allowing the user to observe the remaining amount of liquid matrix in the storage chamber 211 through the sidewall of the main body of the atomizer 21. At least a portion of the housing 6 may be transparent, and the adjacent retaining walls 223 are spaced apart so that the sidewall of the main body of the atomizer 21 facing the housing 6 can be exposed outside the holder 22, so that the holder 22 does not block the view, allowing the user to observe the remaining amount of liquid matrix in the storage chamber 211 through the housing 6 and the sidewall of the atomizer 21 in turn.

[0083] The aerosol generating device includes a power supply 51 and a circuit board 52. The power supply 51 can be any suitable battery, such as a lithium battery. The power supply 51 is electrically connected to the power supply assembly 3 to provide power to the atomizer assembly 2 via the power supply assembly 3. The circuit board 52 includes a control circuit or controller for controlling the power output of the power supply 51, such as controlling the power output from the power supply 51 to the power supply assembly 3, or controlling other operations of the aerosol generating device.

[0084] The housing 6 has a proximal end and a distal end. The aerosol generating device includes a mouthpiece 1, which can be fluidically connected to at least one atomizer 21 at a time. At least a portion of the mouthpiece 1 can be held in the mouth of a user, who inhales the aerosol by suctioning the mouthpiece 1. In the embodiment shown in Figures 2-4, the mouthpiece 1 is connected to the housing 6 and disposed at the proximal end of the housing 6. In other embodiments, the mouthpiece 1 can be integrally formed with the housing 6, such that the mouthpiece 1 is defined by the proximal end of the housing 6.

[0085] The power supply 51 and the circuit board 52 are held in the housing 6. In the embodiment shown in FIG4 , the power supply 51 and the atomizer assembly 2 are arranged side by side in the transverse direction, and the circuit board 52 is arranged longitudinally below the power supply 51 or below the atomizer assembly 2.

[0086] In one embodiment, the atomizer assembly 2 and the power supply assembly 3 can rotate relative to each other along a preset trajectory. By making the atomizer assembly 2 and the power supply assembly 3 move relative to each other, the power supply assembly 3 is made to correspond to the power supply assembly 214 of different atomizers 21, thereby electrically connecting the power supply assembly 3 to different atomizers 21. Therefore, through the relative movement of the atomizer assembly 2 and the power supply assembly 3, the user can select the atomizer 21 electrically connected to the power supply assembly 3 or select the atomizer 21 currently in the working position. The atomizer 21 in the working position can generate aerosol or can generate aerosol under further operation of the user. The atomizer 21 in the non-working position can only generate aerosol or can only generate aerosol under further operation of the user after its power supply assembly 214 corresponds to the power supply assembly 3.

[0087] At least part of the atomizer assembly 2 or the power supply assembly 3 is exposed outside the housing 6 , so that the user can directly drive the atomizer assembly 2 or directly drive the power supply assembly 3 to cause relative displacement between the atomizer assembly 2 and the power supply assembly 3 .

[0088] However, in one embodiment of the present application, the user can drive other components of the aerosol generating device, and use these other components to drive the atomizing assembly 2 or the power supply assembly 3 to move, thereby causing the atomizing assembly 2 and the power supply assembly 3 to move relative to each other. The other component may be the mouthpiece 1 or the drive assembly 4.

[0089] It should be noted that when multiple atomizers 21 are arranged in a straight line in the horizontal direction, the trajectory along which the atomizer assembly 2 and the power supply assembly 3 can move relative to each other is a straight line, i.e., a straight line preset trajectory. When multiple atomizers 21 are arranged in the horizontal direction on the same circumference, the trajectory along which the atomizer assembly 2 and the power supply assembly 3 can move relative to each other is an arc or a circle, i.e., an arc or a circle preset trajectory. When the atomizer assembly 2 and the power supply assembly 3 can rotate 360° relative to each other, the preset trajectory is a circle. When the angle of relative rotation of the atomizer assembly 2 and the power supply assembly 3 is less than 360°, the preset trajectory is an arc.

[0090] In order to reduce the user's fingers touching the mouthpiece 1 and keep the mouthpiece 1 clean and hygienic, and to facilitate the use of the aerosol generating device, it is preferred to use a driving component 4 to drive the power supply component 3 and the atomizing component 2 to move relative to each other along a preset trajectory.

[0091] Based on this, referring to Figures 1 to 4, the aerosol generating device includes a drive assembly 4. The drive assembly 4 includes a drive portion 41. The surface of the drive portion 41 includes a first portion exposed outside the shell 6 and a second portion hidden in the shell 6. The first portion can be operated by the user, and the user can operate the first portion to drive the drive portion 41 to rotate. By rotating the drive portion 41, the first and second portions of the drive portion 41 are interchangeable. Specifically, as the drive portion 41 rotates, the first portion originally exposed outside the shell 6 will be rotated to be hidden in the shell 6, thereby changing from the first portion to the second portion, and the second portion originally hidden in the shell 6 will be exposed outside the shell 6, thereby changing from the second portion to the first portion. It should be noted that in other embodiments, the surface of the drive portion 41 can be completely exposed outside the shell 6.

[0092] The driving portion 41 includes a rotating wheel 411 with a portion of its surface exposed outside the housing 6 to provide for user operation. The rotating wheel 411 may include a surface with teeth to facilitate user operation.

[0093] The driving assembly 4 includes a first connecting portion 42 connected to the driving portion 41. The first connecting portion 42 is connected to the atomizing assembly 2 or the power supply assembly 3, so that when the driving portion 41 rotates, the first connecting portion 42 can drive one of the atomizing assembly 2 and the power supply assembly 3 to rotate, or drive the atomizing assembly 2 and the power supply assembly 3 to rotate at different speeds or directions, thereby causing the atomizing assembly 2 and the power supply assembly 3 to rotate relative to each other.

[0094] When the power supply component 3 corresponds to the power supply component 214 of one of the atomizers 21, the power supply component 3 contacts and is electrically connected to the power supply component 214 of the atomizer 21. When the driving part 41 rotates a preset angle, the power supply component 3 corresponds to the power supply component 214 of the other atomizer 21, and contacts and is electrically connected to the power supply component 214 of the other atomizer 21. The atomizer 21 that was previously electrically connected to the power supply component 3 can now be electrically disconnected from the power supply component 3.

[0095] According to a first aspect of the present application, the atomization assembly 2 and the aerosol generating device provided in some embodiments can reduce the wear of the power supply assembly 3 .

[0096] Specifically, the power collection components 214 of the multiple atomizers 21 are arranged at intervals along the preset trajectory. Among the multiple power collection components 214, a recessed space 24 is provided between at least two adjacent power collection components 214. The recessed space 24 and the power collection components 214 are both arranged on the preset trajectory along which the power supply component 3 rotates relative to the atomizer component 2. During the movement of the atomizer component 2 along the preset trajectory, when the power collection component 214 corresponds to the power supply component 3 of one of the atomizers 21, the power collection component 214 is in electrical contact with the power supply component 3. When the power supply component 3 corresponds to the recessed space 24, the contact force between the atomizer component 2 and the power supply component 3 is reduced, or the atomizer component 2 and the power supply component 3 are separated.

[0097] Thus, during the relative movement of the atomizer assembly 2 and the power supply assembly 3 along a straight preset trajectory or along an arc or circular preset trajectory, the power supply assembly 3 contacts the atomizer assembly 2 during part of the stroke, and the contact force between the power supply assembly 3 and the atomizer assembly 2 is reduced or the two are separated during the remaining stroke. This can reduce the friction between the power supply assembly 3 and the atomizer assembly 2, or shorten the time and stroke of the power supply assembly being rubbed, thereby reducing wear on the power supply assembly 3 and relieving fatigue of the power supply assembly 3, helping to maintain a stable electrical connection and improving the user experience. Furthermore, directly driving the drive assembly 4 can cause the power supply assembly 3 and the atomizer assembly 2 to rotate relative to each other along the preset trajectory, which is simple to operate and easy to use.

[0098] In one embodiment, the power taking component 214 protrudes from the retaining seat 217 toward one end of the power supply component 3, and the two adjacent power taking components 214 are spaced apart from each other, so that a recessed space 24 is formed between the two adjacent power taking components 214, so that the power supply component 214 moves from the power taking component 214 corresponding to one atomizer 21 to the power taking component 214 corresponding to the other atomizer 21 during at least part of the stroke, and the friction between the power supply component 3 and the atomization component 2 is reduced, or the two are separated and have no contact with each other.

[0099] In one embodiment, the atomizer 21 helps define at least a portion of the boundary of the recessed space 24 .

[0100] For example, referring to Figure 7 , a first surface 2171 on the holder 217 of the atomizer 21 surrounds at least a portion of the power extraction assembly 214, and the first surface 217 defines at least a portion of the boundary of the recessed space 24. In the embodiments shown in Figures 8 and 9 , the end surface of the power extraction assembly 214 facing the power supply assembly 3 is not coplanar with the first surface 2171. Instead, the end of the power extraction assembly 214 facing the power supply assembly 3 protrudes relative to the first surface 2171. The first surface 2171 can be a smooth plane, but is not limited thereto.

[0101] Furthermore, the retaining seat 217 also includes a boss 2172. The first surface 2171 is arranged around at least a portion of the boss 2172 and is recessed relative to the boss 2172, so that the boss 2172 protrudes from the first surface 2171. The boss 2172 includes a second surface 21721 arranged facing the power supply component 3. The power extraction component 214 penetrates the boss 2172, so that at least the end face of the power extraction component 214 facing the power supply component 3 is exposed, and the end face of the power extraction component 214 facing the power supply component 3 can be flush with the second surface 21721. In other embodiments, the end of the power extraction component 214 facing the power supply component 3 can protrude from the second surface 21721, so that a step structure is formed between the end and the second surface 21721, and at least a portion of the power extraction component 214 is exposed on the second surface 21721.

[0102] Please refer to Figure 4. The atomizer component 2 and the power supply component 3 are arranged in the longitudinal direction. When the power supply component 3 is elastic, in order to ensure that the power supply component 214 and the power supply component 3 can be elastically abutted, during the relative movement of the power supply component 3 and the atomizer component 2 along the preset trajectory, the maximum deformation of the power supply component 3 in the longitudinal direction can be less than the longitudinal spacing between the first surface 2171 and the second surface 21721, so that when the power supply component 3 corresponds to the first surface 2171, the power supply component can return to its natural height, and there can be a gap between the power supply component 3 and the first surface 2171, so that the two are not in contact. The longitudinal spacing between the first surface 2171 and the second surface 21721 can be designed based on the maximum deformation of the power supply component 3 in the longitudinal direction, or the longitudinal spacing between the first surface 2171 and the second surface 21721 can be used to select an adapted power supply component 3.

[0103] The boss 2172 protrudes relative to the first surface 2171, and thus has a side surface. The side surface can define a partial boundary of the recessed space 24 and connect the first surface 2171 and the second surface 21721. The inclined surface located on the predetermined trajectory can be an inclined surface 21722. Therefore, when the power supply component 3 moves from the position corresponding to the recessed space 24 to the position corresponding to the power extraction component 214, the inclined surface 21722 can guide the end of the elastic power supply component 3 to move to abut against the second surface 21721, preventing the end of the power supply component 3 from being stopped by the side surface of the boss 2172.

[0104] The first power extraction electrode 2141 and the second power extraction electrode 2142 in the power extraction assembly 214 can be positioned adjacent to the edge of the second surface 21721. The air inlet 216 of the atomizer 21 can extend through the boss 2172. The first power extraction electrode 2141, the second power extraction electrode 2142, and the air inlet 216 can be arranged in a triangular shape on the second surface 21721. The air inlet 216 can be positioned outside or within the predetermined trajectory.

[0105] In one embodiment, the retainer 22 participates in defining at least a portion of the boundary of the recessed space 24 .

[0106] For example, the lifting portion 224 defines at least a portion of the boundary of the recessed space 24. Specifically, in one embodiment, referring to FIG. 7 , the power extraction components 214 of the multiple atomizers 21 are arranged around the lifting plate 2242. The surface of the lifting plate 2242 facing away from the power supply component 3 abuts at least a portion of the first surface 2171, and the sidewalls of the lifting plate 2242 define a portion of the boundary of the recessed space 24. In one example, a portion of the sidewalls of the lifting plate 2242 abuts the side of the boss 2172, while the remaining sidewalls of the lifting plate 2242 can define a portion of the boundary of the recessed space 24.

[0107] The supporting frame 2241 is arranged around the power supply components 214 of multiple atomizers 21. The inward side wall of the supporting frame 2241 can extend longitudinally and define the local boundary of the recessed space 24. The side wall of the supporting plate 2242 is arranged opposite to the inward side wall of the supporting frame 2241.

[0108] 7 , the partition plate 221 is exposed toward the end of the power supply assembly 3, and this end defines a partial boundary of the recessed space 24. The end surface of the partition plate 221 facing the power supply assembly 3 can be coplanar with the first surface 2171, and two adjacent first surfaces 2171 can be separated by a partition plate 221.

[0109] In the embodiment shown in FIG. 2 and FIG. 7 , the preset track is an arc-shaped or circular preset track, there are multiple recessed spaces 24 , and the multiple recessed spaces 24 and the multiple power extraction components 214 are alternately arranged along the preset track.

[0110] In one embodiment, the aerosol generating device includes a base 7, and the power supply assembly 3 is fixed to the base 7. Specifically, the first power supply electrode 31 and the second power supply electrode 32 in the power supply assembly 3 are fixed to the base 7. Therefore, when the atomizer assembly 2 and the power supply assembly 3 rotate relative to each other, the atomizer assembly 2 can also rotate relative to the base 7.

[0111] 4 , the base 7 includes an air guide 73 , and the interior of the air guide 73 includes a first air hole 731 . By rotating the atomizer assembly 2 relative to the base 7 , the first air hole 731 is made to correspond to the air inlet 216 of a different atomizer 21 , thereby switching the atomizer 21 in fluid communication with the first air hole 216 .

[0112] To enhance the puffing experience and prevent the gas in the atomizer 21 in the non-operating position from entering the air inlet 216 of the atomizer 21 in the operating position during puffing, the air guide 73 elastically abuts the corresponding atomizer 21, thereby forming a sealed connection with the atomizer 21, isolating the air inlet 216 from the air inlet 216 of the atomizer 21 in the non-operating position. When the air inlet 216 passes through the second surface 21721 and is in fluid communication with the air guide 73, the air guide 73 elastically abuts the second surface 21721.

[0113] When the user inhales the mouthpiece 1 , at least part of the air entering the aerosol generating device enters the corresponding air inlet 216 through the first air hole 731 .

[0114] The recessed space 24 and the air inlet 216 of each atomizer 21 can be arranged on the moving trajectory of the relative movement of the air guide 73 and the atomizer assembly 2, so that when the base 7 and the atomizer assembly 2 rotate relative to each other by an angle, the air guide 73 can correspond to the air inlet 216, thereby being fluidly connected to the air inlet 216. When the base 7 and the atomizer assembly 2 rotate relative to each other by another angle or the base 7 and the atomizer assembly 2 continue to move relative to each other, the air guide 73 can correspond to the recessed space 24, so that the abutment force between the air guide 73 and the atomizer assembly 2 is reduced or the two are separated and contactless, so as to reduce the friction between the air guide 73 and the atomizer assembly 2 or reduce the friction time and friction stroke between the air guide 73 and the atomizer assembly 2, which is beneficial for preventing the air guide 73 from being worn, and is beneficial for maintaining the sealing connection between the first air hole 731 and the corresponding air inlet 216, and can also reduce the resistance when the base 7 or the power supply assembly 3 and the atomizer assembly 2 rotate relative to each other.

[0115] In one embodiment, the base 7 is a component of the circuit board 52. In one embodiment, the circuit board 52 is fixed on the base 7.

[0116] It should be noted that in the first aspect of the present application, the driving component 4 is optional but not mandatory, and can directly drive the atomizing component 2 or directly drive the power supply component 3, so that the atomizing component 2 and the power supply component 3 move relative to each other along a preset trajectory.

[0117] In a second aspect of the present application, in some embodiments of the aerosol generating device, the atomizer assembly 2 is disposed between the mouthpiece 1 and the drive assembly 4, and the drive assembly 4 is connected to the atomizer assembly 2. The drive assembly 4 drives the atomizer assembly 2 to move relative to the power supply assembly 3 or relative to the mouthpiece 1. Therefore, a large gap exists between the drive assembly 4 and the mouthpiece 1, preventing the user from touching the mouthpiece 1 while the drive assembly 4 is rotating, thereby ensuring that the mouthpiece 1 remains clean and hygienic.

[0118] 4 and 5 , the driving assembly 4 includes a first connecting portion 42 , and the atomizing assembly 2 includes a second connecting portion 23 . The first connecting portion 42 is connected to the second connecting portion 23 , thereby connecting the driving assembly 4 to the atomizing assembly 2 .

[0119] 4 , the drive assembly 4 is disposed adjacent to the distal end of the housing 6. Furthermore, the nozzle 1 and the drive assembly 4 may be disposed at opposite ends of the housing 6.

[0120] In one embodiment, referring to FIG. 4 , the air outlet 215 of the atomizer 21 in the working position can be fluidically connected to the mouthpiece 1 , while the air outlet 215 of the atomizer 21 in the non-working position is blocked, so that when the user draws on the mouthpiece 1 , the user mainly inhales the aerosol generated by the atomizer 21 in the working position.

[0121] Based on this, as an example, the mouthpiece 1 is connected to the housing 6. When the drive assembly 4 drives the atomizer assembly 2 to rotate relative to the power supply assembly 3, the atomizer assembly 2 also rotates relative to the mouthpiece 1. The rotation of the atomizer assembly 2 relative to the mouthpiece 1 switches the atomizer 21 in fluid communication with the mouthpiece 1. The rotation of the atomizer assembly 2 relative to the power supply assembly 3 switches the atomizer 21 electrically connected to the power supply assembly 3. Thus, by driving the atomizer assembly 2 to rotate by the drive assembly 4, the mouthpiece 1 can maintain fluid communication with the atomizer 21 in the working position, and the power supply assembly 3 can also maintain electrical connection with the atomizer 21 in the working position.

[0122] In one embodiment, at least a portion of the atomizer assembly 2 is rotatably disposed within a chamber within the housing 6, and at least a portion of the atomizer assembly 2 can be concealed within the chamber, making it inaccessible. The drive assembly 4 can drive the atomizer assembly 2 to rotate within the chamber. By rotating the atomizer assembly 2 within the chamber, the atomizer 21 is alternately positioned between operating positions.

[0123] In one embodiment, referring to FIG. 4 , at least a portion of the base 7 is disposed between the drive assembly 4 and the atomizer assembly 2 , or at least a portion of the base 7 is disposed between the nozzle 1 and the drive assembly 4 .

[0124] Based on this, as an example, the atomizer assembly 2 and the drive assembly 4 are connected to each other through the connection between the first connecting portion 42 and the second connecting portion 23. A through hole 74 is formed on the base 7, and the first connecting portion 42 and / or the second connecting portion 23 passes through the through hole 74 and can rotate in the through hole 74.

[0125] In the embodiment shown in Figures 5, 10, and 11, the first connecting portion 42 and the second connecting portion 23 are nested and connected. Furthermore, the first connecting portion 42 includes a columnar portion 422 and a sleeve 421 disposed around the columnar portion 422. Both the columnar portion 422 and the sleeve 421 extend longitudinally, with a docking space 423 defined between the sleeve 421 and the columnar portion 422. The second connecting portion 23 includes a base and a docking portion. The base is positioned between the support plate 2242 and the docking portion. The base and docking portion may be integrally formed, and there may not be a clear demarcation between them. The columnar portion 422 of the first connecting portion 42 is embedded in the second connecting portion 23, with the end of the columnar portion 422 extending through the docking portion and positioned within the base. The docking portion of the second connecting portion 23 can be embedded in the docking space 423. The second connecting portion 23 can be connected to the support plate 2242. The second connecting portion 23 can be a component of the retaining frame 22. The second connecting portion 23 can be coaxial with the center column 225. The second connecting portion 23 can be an extension of the central column 225, and is connected to the second connecting portion 23 through the first connecting portion 42, so that the central column 225 is interference-connected with the drive assembly 4. When the drive assembly 4 drives the atomizer assembly 2 to rotate, the atomizer assembly 2 rotates around the central axis in the central column 225.

[0126] To prevent the first connection portion 42 and the second connection portion 23 from separating from each other in the longitudinal direction, the first connection portion 42 is snap-fitted to the second connection portion 23. For example, referring to Figures 5, 10, and 11, the second connection portion 23 is provided with a protrusion 231, which can be located on the docking portion, and the first connection portion 42 is provided with a bayonet 424, which can be provided on the sleeve 421. When the first connection portion 42 and the second connection portion 23 are connected, the protrusion 231 is located in the bayonet 424 and interferes with the bayonet 424, so that the first connection portion 42 and the second connection portion 23 cannot be separated in the longitudinal direction. For example, referring to Figures 10 and 11, the second connection portion 23 is provided with a slot 232, and the first connection portion 42 is provided with a block 425. When the first connection portion 42 and the second connection portion 23 are connected, the block 425 is embedded in the slot 232, so that the first connection portion 42 and the second connection portion 23 cannot be separated in the longitudinal direction.

[0127] To prevent the first connecting portion 42 and the second connecting portion 23 from rotating relative to each other, at least a portion of the first connecting portion 42 or at least a portion of the docking space 424 or at least a portion of the second connecting portion 23 is configured as a non-circular structure, as shown in, for example, FIG5, FIG10 and FIG11.

[0128] As an example, referring to Figure 4 , the base 7 has a fluid channel therein, which circulates and connects the outside air and at least one atomizer 21. The trajectory indicated by the arrow in Figure 4 is the trajectory of air entering the atomizer 21 and the nozzle 1 along the fluid channel.

[0129] Specifically, a first air hole 731 is provided on the base 7, and the first air hole 731 is an opening at one end of the fluid channel (air flow outlet), which is arranged toward the atomizer assembly 2. A second air hole 75 is also provided on the base 7, and the second air hole 75 is an opening at the other end of the fluid channel (air flow inlet). When inhaling, air enters the fluid channel through the second air hole 75, and then enters the corresponding atomizer 21 through the first air hole 731.

[0130] A liquid storage space 43 is defined between the drive portion 41 and the first connecting portion 42 of the drive assembly 4. The second air holes 75 are positioned toward the liquid storage space 43, thereby establishing fluid communication between the liquid storage space 43 and the atomizer assembly 2. If liquid in the base 7 leaks through the second air holes 75, it will flow into the liquid storage space 43 of the rotating assembly 4, thereby preventing the liquid from leaking out of the aerosol generating device. In this embodiment, the drive assembly 4 can be operated by the user, rotating the atomizer assembly 2 under the user's operation, while also storing liquid and preventing it from leaking out of the aerosol generating device.

[0131] Furthermore, the first pores 731 and the second pores 75 are staggered in the transverse direction to prevent the condensate or liquid matrix entering from the first pores 731 from directly entering the second pores 75 , thereby preventing the condensate or liquid matrix from leaking through the second pores 75 .

[0132] Furthermore, the base 7 includes a first support plate 71 and a second support plate 72 connected to each other. The air guide 73 and the power supply assembly 3 are engaged with the first support plate 71. Second air holes 75 are provided on the second support plate 72. A gap is defined between the first support plate 71 and the second support plate 72. Part of the gap forms a fluid channel, which is partially used to collect and store incoming condensate or liquid matrix.

[0133] In a third aspect of the present application, in some embodiments of the aerosol generating device, the atomizer assembly 2 is disposed between the mouthpiece 1 and the drive assembly 4, and the drive assembly 4 is connected to the mouthpiece 1. The drive assembly 4 drives the mouthpiece 1 to move relative to the atomizer assembly 2 to switch the atomizer 21 in fluid communication with the mouthpiece 1. Based on this third aspect, the atomizer assembly 2 can be configured to be movable relative to the power supply assembly 3, or can be configured to be immovable relative to the power supply assembly 3.

[0134] In a fourth aspect of the present application, there is provided a method for unlocking the protection lock of the aerosol generating device by relative movement of the atomizing component 2 and the power supply component 3.

[0135] The protection lock is electrically connected to the power supply 51 and / or the circuit board 52. The controller can control the automatic locking and unlocking of the protection lock. Only after the protection lock of the aerosol generating device is unlocked can the aerosol generating device function normally and generate aerosol. The protection lock is provided to prevent unauthorized or inappropriate persons from using the aerosol generating device. The protection lock can automatically lock when the aerosol generating device is in standby or dormant mode.

[0136] Based on the fourth aspect, in one embodiment, after the atomizer assembly 2 and the power supply assembly 3 rotate relative to each other in one direction, for example, in a clockwise direction, or in a counterclockwise direction, and at least three atomizers 21 are electrically connected to the power supply assembly 3 in sequence, the controller controls the protection lock to be unlocked.

[0137] In one embodiment, the protection lock is unlocked by rotating the atomizer assembly 2 and the power supply assembly 3 back and forth relative to each other. Specifically, after the atomizer assembly 2 and the power supply assembly 3 rotate relative to each other in one direction, electrically connecting at least one atomizer 21 to the power supply assembly 3, and then rotating relative to each other in the opposite direction, electrically connecting at least one atomizer 21 to the power supply assembly 3, the protection lock is unlocked.

[0138] A fifth aspect of the present application provides a method for unlocking a protection lock on an aerosol generating device by entering a password. Specifically, the aerosol generating device includes a keypad or a display capable of displaying a keyboard, the keypad or display being electrically connected to a power source and / or a circuit board, and a controller capable of receiving commands input via the keypad or display and responding based on the commands. After a user enters the unlock password via the keypad or display, the controller controls the unlocking of the protection lock.

[0139] Based on the first, second, or third aspects of the present application, when the atomizer assembly 2 is capable of rotating relative to the housing 6, in one embodiment, with reference to FIG. 2 , the retaining frame 22 further includes a first stopper 25, and the housing 6 is provided with a second stopper 61. The first stopper 25 and the second stopper 61 engage with each other when in correspondence, thereby preventing the atomizer assembly 2 from rotating relative to the housing 6. In the embodiment shown in FIG. 2 , the first stopper 25 is provided on the lifting frame 2241, and the second stopper 61 includes a groove, which may be a longitudinally extending strip groove, but is not limited thereto. When at least one atomizer 21 is in the working position, the first stopper 25 corresponds to the second stopper 61, and at least a portion of the first stopper 25 is embedded in the second stopper 61. In other embodiments, the first stopper 25 may be provided on the retaining wall 223.

[0140] The groove in the second stop member 61 has two inclined walls arranged opposite to each other, and the two inclined walls are arranged along the direction of rotation of the atomizer assembly 2 relative to the shell 6, which can guide the first stop member 25 out of the groove, so that when the user provides a larger force to operate the drive assembly 4, the atomizer assembly 2 can overcome the resistance of the interaction between the first stop member 25 and the second stop member 61, thereby rotating relative to the shell 6.

[0141] In one embodiment, when the first stopper 25 cooperates with the second stopper 61 , vibration or sound can be generated to prompt the user that at least one atomizer 21 has been moved to the working position.

[0142] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. 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.
