Description

Technical Field

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

[0002] An aerosol generating device is a device that can atomize a liquid formulation to form an aerosol. In some exemplary prior art, the aerosol generating device includes a mouthpiece assembly, an atomizer assembly, and a power supply assembly. The mouthpiece assembly is provided with a positioning groove, and the atomizer assembly is provided with a positioning protrusion. The atomizer assembly can rotate relative to the mouthpiece assembly to selectively connect an atomizer in the atomizer assembly to the inhalation port of the mouthpiece assembly.

[0003] However, during the rotation of the atomizer assembly relative to the nozzle assembly, the positioning grooves and the positioning protrusions alternate between corresponding settings and mutually staggered settings. Obviously, when the positioning grooves and the positioning protrusions are in a mutually staggered setting, the gap between the nozzle assembly and the atomizer assembly will be significantly increased, thereby affecting the sealing performance between at least part of the atomizer in the atomizer assembly and the nozzle assembly.

[0056] Please refer to Figure 1 and Figure 2 The present application provides an embodiment of an aerosol generating device 100 , which includes a mouthpiece assembly 1 , a power supply assembly 3 and an atomization assembly 2 .

[0057] The atomization assembly 2 includes a plurality of atomizers 21 , each of which is configured to generate aerosol when receiving electrical power.

[0058] At least two of the multiple atomizers 21 can generate aerosols of different flavors. Of course, at least two of the multiple atomizers 21 can also generate aerosols of the same flavor.

[0059] It should be noted that, as used in this application, "a plurality" refers to a number of two or more. Figure 6 and Figure 7 In the illustrated embodiment, there are four atomizers 21 , but the present invention is not limited thereto.

[0060] In some embodiments, the atomizer 21 includes a cup body 211, which may have a storage chamber 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. The fragrance may include, but is not limited to, betel nut extract, menthol, peppermint, spearmint oil, or various fruity aroma components. The flavoring agent may include ingredients that can provide the user with various aromas or flavors. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited to this. 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 atomization.

[0061] At least two of the multiple atomizers 21 can contain different liquid matrices, including liquid matrices with different flavors or liquid matrices with different ingredients or proportions, thereby providing users with different sensory experiences by switching the atomizers 21. Of course, in some embodiments, at least two of the multiple atomizers 21 can contain the same liquid matrices.

[0062] You can refer to Figure 2 A liquid storage cotton 212 may be provided in the storage cavity to retain at least a portion of the liquid matrix in the liquid storage cotton 212. The liquid storage cotton 212 is provided to prevent leakage of the liquid matrix. The liquid storage cotton 212 is optional but not mandatory.

[0063] You can refer to Figure 2 The atomizer 21 may further include an atomizing core 213 , which is in fluid communication with the storage chamber or connected to the liquid storage cotton 212 . The atomizing core 213 is used to atomize the liquid matrix to generate an aerosol.

[0064] For example, 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 a liquid matrix and directing the liquid matrix into an atomization range of the heating element. The heating element is configured 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 liquid absorbing element form a single unit.

[0065] The atomizer 21 may further include a power extraction electrode 214 electrically connected to the atomizing core 213 in the atomizer 21 .

[0066] The power electrode 214 can be connected to the heating element to conduct current. The power electrode 214 is used to electrically connect to the power supply component 3. The atomizing core 213 obtains electrical power from the power supply component 3 through the power electrode 214, and then atomizes the liquid matrix to generate aerosol.

[0067] The power-taking electrode 214 may include a first power-taking electrode and a second power-taking electrode. The first power-taking electrode and the second power-taking electrode may be a positive electrode and a negative electrode, respectively, and may be electrically connected to the opposite ends of the heating element, and may be electrically connected to the positive and negative electrodes of the power supply 51, respectively, through the power supply component 3.

[0068] The atomizer 21 may further include a holder 217, which is engaged with the power extraction electrode 214 and is used to hold or support the power extraction electrode 214. The holder 217 may be connected to the end of the cup body 211. The power extraction electrode 214 may pass through the holder 217.

[0069] The atomizer 21 may further include an air inlet 216 fluidly connected to the atomizer core 213 . Air may enter the interior of the atomizer 21 through the air inlet 216 and then flow toward the atomizer core 213 .

[0070] The atomizer 21 may also have 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 of the atomizing core 213 is guided to the air outlet 215 via the air supply channel, and then enters the mouthpiece assembly 1 through the air outlet 215. The storage chamber can be arranged around the air supply channel, or the air supply channel can be arranged on one side of the storage chamber.

[0071] In one example, the atomizer 21 may have an atomizing compartment in fluid communication with the storage chamber, 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 is located between the air outlet and the atomizing compartment.

[0072] Alternatively, in another example, reference may be made to Figure 2 At least a portion of the atomizer core 213 is arranged in the air supply channel, and a liquid guide hole is opened on the air supply channel. The atomizer core 213 is fluidically connected to the storage chamber or connected to the liquid storage cotton 212 through the liquid guide hole. The liquid matrix in the storage chamber 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 to absorb and conduct the liquid matrix.

[0073] In some embodiments, 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, Figure 6 and Figure 7, multiple atomizers 21 can be arranged in an array in the horizontal direction, or arranged in the same ring in the horizontal direction.

[0074] In some embodiments, reference may be made to Figure 6 and Figure 7 The atomization assembly 2 further includes a holder 22 , which is used to hold a plurality of atomizers 21 .

[0075] 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.

[0076] 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.

[0077] In such Figure 6 and Figure 7 In the embodiment shown, the inner sides of the plurality of partition plates 221 may intersect. The plurality of partition plates 221 may be radially distributed. When the atomizer 21 is accommodated in the corresponding holding space 222, the atomizer 21 may be supported by the lifting portion 224.

[0078] A retaining wall 223 is provided outside the partition plate 221 . 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 the atomizer 21 from detaching from the holder 22 in the transverse direction.

[0079] You can refer to Figure 6 and Figure 7 The spacing between two adjacent retaining walls 223 is beneficial to reducing the material consumption of processing the retaining frame 22 and reducing costs, and is also beneficial to reducing the volume of the aerosol generating device, so that the aerosol generating device meets the development needs of miniaturization.

[0080] The power supply assembly 3 may include 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 may be a positive electrode and a negative electrode, respectively, and may be electrically connected to the positive and negative electrodes of the power source 5. When the power supply assembly 3 is aligned with the atomizer 21, the first power supply electrode 31 and the second power supply electrode 32 may contact the first power extraction electrode and the second power extraction electrode, respectively. The power supply assembly 3 is configured to selectively direct current to at least one of the multiple atomizers 21.

[0081] The power supply assembly 3 may further include a base 33 , and the first power supply electrode 31 and the second power supply electrode 32 may be fixed on the base 33 .

[0082] The base 33 can be used to atomize the assembly 2 in the longitudinal direction. Figure 2 In the illustrated embodiment, the power supply assembly 3 and the atomizer assembly 2 are arranged in the longitudinal direction, and the power supply 5 is arranged on one side of the atomizer assembly 2 and / or the power supply assembly 3 in the transverse direction.

[0083] The contact between the power supply component 3 and the power extraction electrode 214 may be elastic contact to increase the stability of the contact between the power supply component 3 and the power extraction electrode 214 .

[0084] In some embodiments, the power supply component 3 is elastic, for example, the first power supply electrode 31 and / or the second power supply electrode 32 is a spring needle, or for example, the first power supply electrode 31 and / or the second power supply electrode 32 includes a spring sheet, and the spring needle or spring sheet is used to elastically abut the power taking electrode 214.

[0085] In some embodiments, the mouthpiece assembly 1 can be simultaneously fluidically connected to at least one atomizer 21 in the atomizer assembly 2. The mouthpiece assembly 1 includes an inhalation port 113, through which aerosol generated by the atomizer 21 is released outside the aerosol generating device 100. Furthermore, at least a portion of the mouthpiece assembly 1 can be held in the mouth of a user, who inhales the aerosol released from the inhalation port 13 by inhaling the mouthpiece assembly 1.

[0086] In some embodiments, at least one nebulizer 21 in the nebulization assembly 2 can be selected to be in fluid communication with the air inlet 13 and / or electrically connected to the power supply assembly 3. The nebulizer 21 that is in fluid communication with the air inlet 13 and electrically connected to the power supply assembly 3 is defined as the target nebulizer. Therefore, at least one nebulizer 21 in the nebulization assembly 2 can be selected to be the target nebulizer.

[0087] For example, the atomizer assembly 2 is configured to rotate relative to the nozzle assembly 1 so that through the relative rotation between the two, one or more atomizers 21 can be selectively made to become the target atomizer, and the target atomizer can be fluidically connected to the air inlet 113, and the target atomizer can be electrically connected to the power supply assembly 3, so that the target atomizer can obtain electrical power and generate aerosol, and the aerosol generated by the target atomizer can be released to the outside through the air inlet 113.

[0088] It should be noted that selectively making one or more of the atomizers 21 the target atomizer by relative rotation between the atomizer assembly 2 and the suction nozzle assembly 1 is optional and not mandatory. One or more atomizers 21 can also be selected as the target atomizer by other methods. For example, the atomizer assembly 2 can be translated relative to the suction nozzle assembly 1 to selectively make one or more of the atomizers 21 the target atomizer; or, for example, the atomizer assembly 2 can remain relatively stationary relative to the suction nozzle assembly 1, and multiple atomizers 21 can be simultaneously in fluid communication with the suction port 113, and then the power supply assembly 3 can be rotated or translated relative to the atomizer assembly 2 to selectively make one or more of the atomizers 21 the target atomizer.

[0089] In some embodiments, reference may be made to Figure 6 and Figure 7 The atomizer assembly 2 is provided with a first positioning mechanism 23, and the aerosol generating device 100 further includes a second positioning mechanism 4. One of the first positioning mechanism 23 and the second positioning mechanism 3 comprises a recess, and the other comprises a projection. When the atomizer assembly 2 rotates relative to the mouthpiece assembly 1, the recess simultaneously rotates relative to the projection. When the projection and recess align, the aerosol generating device 100 generates a sensory signal indicating that one or more atomizers 21 have become target atomizers, thereby allowing the user to stop rotating the atomizer assembly 2 relative to the mouthpiece assembly 1.

[0090] However, during the rotation of the recess relative to the projection, the recess and projection can rotate from a mutually aligned position to a staggered position, or from a staggered position to a mutually aligned position. When the two are aligned, at least a portion of the projection can be located within the recess. When the two are staggered, the projection is located outside the recess. Thus, during the rotation of the recess relative to the projection, or during the rotation of the atomizer assembly 2 relative to the nozzle assembly 1, the atomizer assembly 2 will float in the longitudinal direction.

[0091] In existing aerosol generating devices, during the movement (including but not limited to rotation or translation) of the atomizer assembly relative to the mouthpiece assembly, the vertical height position of the mouthpiece assembly cannot be changed. Consequently, the vertical gap between the atomizer assembly and the mouthpiece assembly can change. When the vertical gap between the atomizer assembly and the mouthpiece assembly increases, the air outlet of the atomizer may communicate with the outside air, potentially disrupting the air pressure balance within the atomizer and causing leakage of the liquid matrix. Furthermore, this may increase the amount of air entering the storage chamber, causing oxidation of the liquid matrix.

[0092] In order to maintain a good seal between the atomizer assembly 2 and the nozzle assembly 1 during the process of selecting the target atomizer, in some embodiments, reference may be made to Figure 4 and Figure 5The nozzle assembly 1 includes a first part 11, a second part 12 and a first elastic member 13. The air inlet 113 is provided on the first part 11, the second part 12 abuts the atomizer assembly 2, and the second part 12 can fluidically connect the atomizer assembly 2 with the air inlet 113 on the first part 11, and the first elastic member 13 connects the first part 11 and the second part 12. Among them, the first elastic member 13 can undergo elastic deformation in the longitudinal direction and can provide elastic force based on the elastic deformation so that the second part 12 can float in the longitudinal direction. Thus, when the atomizer assembly 2 floats in the longitudinal direction, based on the mutual abutment between the atomizer assembly 2 and the second part 12, the second part 12 can float in the longitudinal direction along with the atomizer assembly 2. Thus, during the relative rotation of the atomizer assembly 2 and the nozzle assembly 1, the abutment force between the atomizer assembly 2 and the second part 12 in the longitudinal direction will not be reduced substantially, so that the abutment between the atomizer assembly 2 and the second part 12 can maintain a sealed abutment. In other words, the elastic force provided by the first elastic member 13 can enable the second portion 12 to maintain sealing contact with the atomizer assembly 2 in the longitudinal direction.

[0093] The nebulizer 21 may further include an end cap 218 connected to the proximal end of the cup body 211 and a flexible plug 219 retained on the end cap 218, wherein the flexible plug 219 is provided with the above-mentioned air outlet 215. When the recess and the protrusion are aligned, the flexible plug 219 elastically abuts the second portion 12, so that the flexible plug 219 can sealably abut the second portion 12. The first elastic member 13 can provide elastic force, increasing the abutting force between the flexible plug 219 and the second portion 12, making the sealing connection between the flexible plug 219 and the second portion 12 more reliable, further preventing the gas in the target nebulizer and the aerosol condensate flowing back from the mouthpiece assembly 1 from leaking from the second portion 12 and the flexible plug 219, and further preventing the outside gas or the gas and aerosol condensate in other nebulizers 21 from spreading from the second portion 12 and the flexible plug 219 to the air outlet 215 of the target nebulizer.

[0094] When the depression and the protrusion are staggered, the first elastic member 13 can continue to provide elastic force, so that the second part 12 continues to maintain a good sealing contact with the atomizer assembly 2 in the longitudinal direction, thereby continuing to prevent the gas in the target atomizer and the aerosol condensate flowing back from the mouthpiece assembly 1 from leaking from between the second part 12 and the flexible plug 219, and continue to prevent external gas or gas and aerosol condensate in other atomizers 21 from spreading from between the second part 12 and the flexible plug 219 to the air outlet 215 of the target atomizer.

[0095] In some embodiments, the protrusion comprises a rigid protrusion that does not significantly deform when squeezed. In some embodiments, the protrusion comprises an elastic protrusion that can yield when squeezed. The elastic protrusion may comprise a spring that is at least partially tilted. The elastic protrusion may be disposed on the spring. The elastic protrusion may comprise a spherical body or a hemispherical body, and may further comprise a flexible body connected to the spherical body or hemispherical body, wherein the flexible body deforms when squeezed.

[0096] In some embodiments, the atomizer assembly 2 is provided with a first track 24, and at least a portion of the first positioning mechanism 23 is provided on the first track 24; the aerosol generating device 100 further includes a second track 6, and at least a portion of the second positioning mechanism 4 is provided on the second track 6. During the relative rotation of the atomizer assembly 2 and the mouthpiece assembly 1, the protrusion rotates along the first track 24 or along the second track 6. When the protrusion and the recess are aligned, the longitudinal spacing between the first track 24 and the second track 6 is smaller than the longitudinal spacing between the first track 24 and the second track 6 when the protrusion and the recess are staggered. Furthermore, when the protrusion and the recess are aligned, the first track 24 and the second track 6 may contact each other, and when the protrusion and the recess are staggered, the first track 24 and the second track 6 are spaced apart from each other.

[0097] In some embodiments, the number of at least one of the first positioning mechanisms 23 on the first track 24 and the second positioning mechanisms 4 on the second track 6 is equal to the number of the atomizers 21 .

[0098] In some embodiments (not shown), a second positioning mechanism is provided on the mouthpiece assembly, and at least a portion of the first positioning mechanism on the atomizer assembly is positioned toward the mouthpiece assembly. When the atomizer assembly and the mouthpiece assembly are rotated relative to each other until corresponding protrusions are aligned with corresponding recesses, the aerosol generating device vibrates and may also emit an audible sound as a sensory signal to the user that the inhalation port is in fluid communication with one or more atomizers, or that a new target atomizer is in place.

[0099] In some embodiments, the atomizer assembly 2 is configured to rotate simultaneously relative to the mouthpiece assembly 1 and the power supply assembly 3. While the atomizer assembly 2 rotates relative to the mouthpiece assembly 1, the atomizer assembly 2 also rotates relative to the power supply assembly 3. Thus, through rotation, a new target atomizer replaces the original target atomizer and is fluidically connected to the air inlet 113. The new target atomizer can also replace the original target atomizer and be electrically connected to the power supply assembly 3.

[0100] In this embodiment, the power supply assembly 3 may be provided with a second positioning mechanism 4, and at least a portion of the first positioning mechanism 23 on the atomizer assembly 2 is disposed toward the power supply assembly 3. When the atomizer assembly 2 and the power supply assembly 3 rotate relative to each other until the corresponding protrusions are aligned with the corresponding recesses, the aerosol generating device 100 vibrates and may also emit a sound as a sensory signal to the user that the power supply assembly 3 is electrically connected to one or more atomizers 21, or to the user that a new target atomizer is in place.

[0101] As a typical example, you can parameter Figure 6 and Figure 7 The first positioning mechanism 23 includes a recess provided on the distal end of the holder 22 in the atomizer assembly 2 , and the second positioning mechanism 4 includes a protrusion provided on the base 33 in the power supply assembly 3 .

[0102] In some embodiments, reference may be made to Figure 1 and Figure 2 The aerosol generating device 100 further includes a housing 7, in which the atomizer assembly 2 is rotatably disposed. The mouthpiece assembly 1 and the power supply assembly 3 are both configured to be stationary relative to the housing 7. Therefore, by driving the atomizer assembly 2 to rotate within the housing 7, the atomizer assembly 2 can simultaneously rotate relative to the mouthpiece assembly 1 and the power supply assembly 3.

[0103] In such Figure 1 and Figure 3 In the illustrated embodiment, a window 71 is provided on the housing 7 , and at least a portion of the cup 211 of the target atomizer is disposed corresponding to the window 71 , so that the cup 211 of the target atomizer can be visually observed through the window 71 .

[0104] Furthermore, at least a portion of the sidewall of the cup body 211 of the nebulizer 21 may be transparent, allowing the user to observe the remaining amount of the liquid matrix in the storage chamber through the sidewall of the cup body 211 of the nebulizer 21. The two adjacent retaining walls 223 are spaced apart from each other so that the outside of the cup body 211 of the nebulizer 21 is exposed, so that the holder 22 does not block the view, allowing the user to observe the remaining amount of the liquid matrix in the storage chamber through the window on the housing 6 and the cup wall of the target nebulizer 21.

[0105] In some embodiments, the window 71 is configured to be passable, so that a user can operate the atomizer assembly 2 through the window 71 , thereby driving the atomizer assembly 2 to rotate in the housing 7 .

[0106] In some embodiments, reference may be made to Figure 2 The power supply assembly 3 is arranged in the shell 7, and the power supply assembly 3 and the atomization assembly 2 are arranged longitudinally in the shell.

[0107] In some embodiments, reference may be made to Figure 2 and Figure 6 The aerosol generating device 100 further includes an operating member 8 , which is configured for a user to operate and thereby drive the atomizing assembly 2 to rotate.

[0108] At least a portion of the operating member 8 is exposed outside the aerosol generating device 100 so as to be operable by a user.

[0109] In such Figure 2 、 Figure 6 and Figure 7 In the illustrated embodiment, the atomizer assembly 2, the power supply assembly 3 and the operating member 8 are arranged in sequence along the longitudinal direction. A first connecting column 225 is also provided at the distal end of the retaining frame 22. The operating member 8 includes an operating portion 81 for user operation and a second connecting column 82 connected to the operating portion 81. A through hole 331 is provided on the base 33. At least a portion of the first connecting column 225 and at least a portion of the second connecting column 82 can be rotatably arranged in the through hole 331, and the first connecting column 225 and the second connecting column 82 are connected in the through hole 331, so that the first connecting column 225 can rotate with the second connecting column 82, and then the operating portion 81 can drive the retaining frame 22 to rotate, and then the atomizer 21 retained in the retaining frame 22 can rotate together with the retaining frame 22.

[0110] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 further includes a second elastic member 9 , which connects the power supply assembly 3 and the operating member 8 or the housing 7 to provide elastic force so that the power supply assembly 3 floats in the longitudinal direction during the rotation relative to the atomizing assembly 2 .

[0111] The first elastic member 13 and the second elastic member 9 can be the same, for example, the first elastic member 13 and the second elastic member 9 can both be springs, or both be silicone members. The first elastic member 13 and the second elastic member 9 can also be different, for example, the first elastic member 13 can be a spring, and the second elastic member 9 can be a silicone member.

[0112] The elastic force provided by the second elastic member 9 can make the floating direction of the power supply assembly 3 in the longitudinal direction opposite to the floating direction of the atomizer assembly 2 in the longitudinal direction.

[0113] During the relative rotation of the atomizer assembly 2 and the power supply assembly 3, the protrusions and recesses change from being arranged in correspondence to being arranged in a staggered manner, or vice versa, causing the atomizer assembly 2 to float in the longitudinal direction. If the power supply assembly 3 were unable to float in the longitudinal direction, then when the protrusions and recesses were arranged in a staggered manner, the abutting force of the nozzle assembly 1 on the atomizer assembly 2 would be significantly increased, and the force between the atomizer assembly 2 and the base 33 would also be significantly increased, resulting in an increase in the friction between the atomizer assembly 2 and the base 33, or the friction applied to the protrusions. This would hinder the relative rotation of the atomizer assembly 2 and the power supply assembly 3 and would also easily wear the protrusions.

[0114] After the second elastic member 9 is set, when the protrusion and the recess are staggered, the atomizer assembly 2 moves in a direction away from the power supply assembly 3. The second elastic member 9 can be forced to contract when the force between the atomizer assembly 2 and the base 33 increases, so that the power supply assembly 3 moves in a direction away from the atomizer assembly 2, thereby reducing the abutment force between the atomizer assembly 2 and the base 33, and further reducing the friction between the atomizer assembly and the base 33 and the wear suffered by the protrusion. When the protrusion and the recess are set correspondingly, the atomizer assembly 2 moves in a direction close to the power supply assembly 3. The second elastic member 9 can rebound when the force between the atomizer assembly 2 and the base 33 decreases, so that the power supply assembly 3 moves in a direction close to the atomizer assembly 2. This not only increases the intensity of the sensory signal, but also helps prevent the atomizer assembly 2 from rotating, making the electrical connection between the target atomizer and the power supply assembly 3 more stable and preventing the target atomizer from being misaligned with the nozzle assembly 1, resulting in gas leakage between the target atomizer and the air inlet 113.

[0115] In such Figure 2 In the illustrated embodiment, the second elastic member 9 is disposed in the through hole 331 of the base 33 .

[0116] The aerosol generating device 100 may further include a power supply 51 and a circuit board 52. The power supply 51 may be any suitable battery, such as a lithium battery. The power supply 51 is electrically connected to the power supply assembly 3 to provide electrical 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 of the power supply 51 to the power supply assembly 3, or controlling other operations of the aerosol generating device.

[0117] The circuit board 52 is electrically connected to the first power supply electrode and the second power supply electrode. The first power supply electrode and the second power supply electrode are electrically connected to the positive electrode and the negative electrode of the power source 51 through the circuit board 52 .

[0118] The power supply 51 and the circuit board 52 may also be retained in the housing 7 . The circuit board 52 may be fixed to the base 33 .

[0119] It should be noted that, in other embodiments, the atomizer assembly is disposed in the housing and can remain relatively stationary with respect to the housing, the nozzle assembly is rotatably connected to the housing, the power supply assembly is rotatably disposed in the housing or the power supply assembly is rotatably connected to the housing, and the power supply assembly is arranged in linkage with the nozzle assembly. Thus, the nozzle assembly and the power supply assembly can be driven to rotate relative to the housing by operating the nozzle assembly or the power supply assembly, so that the nozzle assembly and the power supply assembly rotate relative to the atomizer assembly. Of course, an operating member can also be provided, and the user can operate the operating member to drive the nozzle assembly and the power supply assembly to rotate relative to the housing, so that the nozzle assembly and the power supply assembly rotate relative to the atomizer assembly.

[0120] In some embodiments, the atomizer assembly 2 is disposed in the housing 7, and the first portion 11 of the nozzle assembly 1 is connected to the proximal end of the housing 7. During the rotation of the atomizer assembly 2 relative to the nozzle assembly 1, the first portion 11 remains stationary relative to the housing 7, and the first elastic member 13 provides elastic force, causing the second portion 12 to float longitudinally relative to the housing 7.

[0121] The second portion 12 may be located inside the housing 7 and may be shielded by the first portion 11, thereby hiding the second portion 12. Therefore, when the second portion 12 floats in the longitudinal direction, the appearance of the aerosol generating device 100 is not affected.

[0122] The first portion 11 of the nozzle assembly 1 may be fixedly connected to the housing 7. The first portion 11 of the nozzle assembly 1 may be integrally formed with the housing 7.

[0123] In some embodiments, reference may be made to Figure 2 The second portion 12 includes a hollow flexible member 121 , the flexible member 121 elastically abuts against the first portion 11 , and the flexible member 121 fluidly connects the air inlet 113 and the target atomizer.

[0124] The flexible member 121 is elastic. Preferably, the flexible member 121 is made of silicone. When the first portion 11 is stationary relative to the housing 7 and the second portion 12 is floating longitudinally relative to the housing 7, the flexible member 121 can deform, maintaining a sealing contact with the first portion 11, thereby preventing condensate and aerosol from leaking through the connection between the flexible member 121 and the first portion 11.

[0125] In such Figure 2 、 Figure 4 and Figure 5In the illustrated embodiment, the second portion 12 further includes an abutting portion 122 for abutting the atomizer assembly 2. A through hole 1221 is defined in the abutting portion 122. The flexible member 121 is disposed between the abutting portion 122 and the first portion 11, and the through hole 1221 fluidically connects the target atomizer to the flexible member 121. Thus, the flexible member 121 is spaced apart from the atomizer assembly 2. During relative rotation between the atomizer assembly 2 and the nozzle assembly 1, lateral interference with the flexible member 121 is reduced, thereby maintaining a well-sealed connection between the flexible member 121 and the first portion 11.

[0126] The first part 11 may include a main body 111 and an air guide tube 115. The main body 111 may be provided with a mouthpiece 114 that can be held by the user's lips, and the air inlet 112 may be provided at the proximal end of the mouthpiece 114. The proximal end of the air guide tube 115 is connected to the mouthpiece 114 and communicates with the air inlet 113. The distal end of the air guide tube 115 is connected to the flexible member 121 in an interlocking manner, and the two are interference fit, so that a sealing connection is achieved between the air guide tube 115 and the flexible member 121. Figure 2 In the embodiment, the distal end of the airway tube 115 is inserted into the flexible member 121 with interference fit and is longitudinally supported by the step structure in the flexible member 121 , so that the airway tube 115 cannot pass through the flexible member 121 longitudinally.

[0127] On the side of the abutment portion 122 facing the first part 11, a first retaining wall 1222 can be provided corresponding to the through hole 1221. The first retaining wall 122 can be roughly annular or frame-shaped, and the flexible part 121 is surrounded by the first retaining wall 1222, so that the flexible part 121 is retained on the abutment portion 122.

[0128] The first elastic member 13 can be arranged between the abutment portion 122 and the main body 111 so that the first elastic member 13 is spaced apart from the atomizer assembly 2. On the side of the abutment portion 122 facing the first part 11, a second retaining wall 1223 and a third retaining wall 1224 can be provided. The second retaining wall 1223 and the third retaining wall 1224 can be concentric rings, wherein the third retaining wall 1224 is located on the inner side of the second retaining wall 1223, and the second retaining wall 1223 and the third retaining wall 1224 are spaced apart. The distal end of the first elastic member 13 is located between the second retaining wall 1223 and the third retaining wall 1224. The proximal end of the first elastic member 13 abuts the main body 111. The second retaining wall 1223 and the third retaining wall 1224 can enable the first elastic member 13 to mainly produce elastic deformation in the longitudinal direction when the atomizer assembly 2 and / or the second part 12 float in the longitudinal direction.

[0129] Please refer to Figure 1-Figure 3 The present application provides an embodiment of an aerosol generating device 100 , which includes a mouthpiece assembly 1 , a power supply assembly 3 , an atomization assembly 2 and a shell 7 .

[0130] The atomizing assembly 2 is disposed in the housing 7 , and the atomizing assembly 2 may be the atomizing assembly 2 provided in any of the above embodiments.

[0131] The nozzle assembly 1 is locked in the first position of the housing, and is configured to be unlocked from the housing 7 when the nozzle assembly 1 is in the second position so as to be rotatable relative to the housing.

[0132] The nozzle assembly 1 includes an air inlet 113 and a first elastic member 13. The first elastic member 13 is configured to provide elastic force to abut against the housing 7 or the atomizer assembly 2, so that the nozzle assembly 1 can be maintained in the first position and can be pressed to the second position. The nozzle assembly 1 can be the nozzle assembly 1 provided in any of the above embodiments.

[0133] In some embodiments, the mouthpiece assembly 1 is detachably connected to the housing 7 so that the mouthpiece assembly 1 can be removed from the housing 7. After the mouthpiece assembly 1 is removed, at least a portion of the atomizer 21 can be exposed. The atomizer 21 can be configured to be removable from the proximal end of the housing 7, so that after the mouthpiece assembly 1 is removed, the atomizer 21 with insufficient or depleted liquid matrix in the housing 7 can be removed, and then a new atomizer 21 can be loaded into the housing 7. Of course, after the mouthpiece assembly 1 is removed, one or more atomizers 21 of a new flavor can be used to replace one or more atomizers 21 in the housing 7.

[0134] The user can remove the nozzle assembly 1 from the proximal end of the housing 7 by operating the first portion 11. Therefore, the second portion 12 is movably connected to the first portion 11, so that the second portion 12 can float relative to the first portion 11 in the longitudinal direction and can be removed from the housing 7 together with the first portion 11.

[0135] Based on this, in some embodiments, reference may be made to Figure 4 and Figure 6 The first part 11 includes a first annular wall 112 connected to the main body 111, and the second part 12 includes a second annular wall 123 connected to the abutment portion 121. A hook portion 14 is provided on one of the first annular wall 112 and the second annular wall 123, and a groove portion 15 is provided on the other, and the hook portion 14 is configured to float longitudinally in the groove portion 15.

[0136] In some embodiments, reference may be made to Figure 2-Figure 5A protrusion 16 is provided on the side of the suction nozzle assembly 1, and a stop block 72 is provided on the inner wall of the shell 7; the stop block 72 includes a first side wall 721 extending toward the proximal end of the shell 7 and a second side wall 722 arranged away from the proximal end of the shell 7 and extending laterally, the protrusion 16 is configured to be movable along the first side wall 721 to a corresponding setting with the second side wall 722, and the first elastic member 13 is configured to provide elastic force so that the protrusion 16 and the second side wall 722 interfere with each other in the longitudinal direction.

[0137] When the second side wall 722 is located between the proximal end of the housing 7 and the protrusion 16 in the longitudinal direction, the suction nozzle assembly 1 cannot be removed from the housing 7 in the longitudinal direction.

[0138] When the second portion 12 floats in the longitudinal direction, the projection 16 and the second side wall 722 can maintain interference fit in the longitudinal direction based on the elastic force provided by the first elastic member 13 , thereby allowing the first portion 11 to remain stationary relative to the housing 7 in the longitudinal direction.

[0139] In some embodiments, reference may be made to Figure 3-Figure 5 The protrusion 16 includes a wide portion 161 and a narrow portion 162 disposed proximal to the wide portion 161. The stop block 72 also includes a third side wall 723. The second side wall 722 is located between the first side wall 721 and the third side wall 723. The protrusion 16 can rotate along the second side wall 722 to the end point (second position) of the second side wall 722. The first elastic member 13 is configured to provide an elastic force so that the wide portion 161 and the second side wall 722 have an interference fit in the longitudinal direction, and the narrow portion 162 is disposed corresponding to the third side wall 723. Therefore, under the elastic force of the first elastic member 13, the protrusion 16 is maintained in the first position, so that the nozzle assembly 1 and the housing 7 are locked and cannot rotate relative to each other.

[0140] In such Figure 6 and Figure 7 In the illustrated embodiment, the protrusion 16 is disposed on the first annular wall 112 .

[0141] Therefore, when the suction nozzle assembly 1 needs to be removed from the shell 7, it is necessary to first press the first part 11 so that the narrow part 162 on the protrusion 16 is staggered with the third side wall 723 in the longitudinal direction, so that the suction nozzle assembly 1 moves from the first position to the second position; when the narrow part 162 and the third side wall 723 are staggered in the longitudinal direction, that is, when the suction nozzle assembly 1 is in the second position, the wide part 161 is spaced apart from the second side wall 722; then rotate the first part 11, and the second part 12 can rotate with the first part 11, so that the protrusion 16 rotates along the second side wall 722 toward the direction of the first side wall 721; then, drag the first part 11 so that the first part 11 moves along the first side wall 721, and under the action of the hook 14, the second part 12 moves with the first part 11 until the suction nozzle assembly 1 is detached from the shell 7.

[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.
