Description

TECHNICAL FIELD

[0001] The present application relates to the field of aerosol generation technology, in particular to an aerosol generating device. BACKGROUND

[0002] An aerosol generating device is a device capable of atomizing an aerosol generating material to form an aerosol. In some exemplary prior art, there is an aerosol generating device comprising a mouthpiece assembly and an atomization assembly comprising a plurality of atomizers, the mouthpiece assembly comprising a base and a mouthpiece disposed on the base, the atomization assembly and the mouthpiece assembly interfering with each other in a transverse direction so as to interlock to prevent relative rotation of the atomization assembly and the mouthpiece assembly, and at this time one of the atomizers is in fluid communication with the mouthpiece, when it is necessary to change the atomizer in fluid communication with the mouthpiece, the user needs to lift the mouthpiece assembly to release the transverse interference between the two, and then rotate the mouthpiece assembly relative to the atomization assembly, thereby changing the atomizer in fluid communication with the mouthpiece of the mouthpiece assembly.

[0003] Since only one of the atomizers is allowed to be in fluid communication with the mouthpiece at the same time, the mouthpiece is disposed at a position deviated from the center of the base so that the central axis of the mouthpiece and the central axis of the atomizer in fluid communication with the mouthpiece are arranged in line when the mouthpiece assembly and the atomization assembly are interlocked.

[0004] However, during the process of lifting the mouthpiece assembly to unlock and rotating the mouthpiece assembly relative to the atomization assembly, since the upward displacement stroke of the mouthpiece assembly is small and the base of the mouthpiece assembly is inclined due to uneven force on the eccentric lifting, the problem that part of the base has escaped from the transverse interference with the atomization assembly and the other part still has transverse interference with the atomization assembly occurs, causing the user to easily jam or operate unsmoothly during the switching of the atomizers, thereby affecting the user's operation feeling. SUMMARY

[0022] The main body further includes a support assembly rotatably assembled with the rotating part.

[0023] The base body is configured to be supported by the support assembly when in the first position, and the first surface is substantially flush with a proximal end of the stop edge.

[0024] As an example, the base body includes a base plate, the base plate includes a first surface and a second surface arranged oppositely, and the operating part is arranged on the first surface.

[0025] The main body further includes a support assembly rotatably assembled with the rotating part, and the support assembly includes a support surface extending transversely, and the second surface is arranged to face the support surface.

[0026] When the base body is in the first position, the second surface is parallel to the support surface.

[0027] As an example, the support assembly is provided with a plurality of air guiding passages, each of which is in fluid communication with one of the atomizers, and the air inlet is configured to be in fluid communication with one of the air guiding passages and the atomizer corresponding to the air guiding passage when the base body is in the first position.

[0032] As an example, the through holes include first through holes arranged towards the mouthpiece, and the second surface is provided with an annular convex rib, the annular convex rib is located in one of the first through holes when the base body is in the first position, and an outer diameter of the annular convex rib is smaller than a hole diameter of the first through holes.

[0055] Please refer to Figures 1-4 Some embodiments of the present application provide an aerosol generating device 100, which includes a main body 2 and a mouthpiece 1. The main body 2 includes a plurality of atomizers 21, which can generate aerosol in a working state. The mouthpiece 1 has a suction port 11, and at least a part of the mouthpiece 1 can be held by the user's mouth. When the user holds the mouthpiece 1, the suction port 11 is arranged towards the inside of the user's oral cavity, so that the user can suck the aerosol generated by the atomizer 21 by sucking the mouthpiece 1.

[0056] It should be noted that "a plurality of" as described in the present application means two or more. For example, please refer to Figure 2The body 2 can include two atomizers 21 arranged in a first direction in a lateral direction, or, not shown, the body can include three atomizers arranged in an equilateral triangle in a lateral direction, or, not shown, the body can include more than three atomizers arranged evenly around a central axis of the body in a lateral direction.

[0057] In some embodiments, the atomizer 21 includes a storage cavity for storing the aerosol generating substrate, and further includes an atomizing core 211 for atomizing, evaporating or overflowing the flavoring components in the aerosol generating substrate.

[0058] In some embodiments, the aerosol generating substrate includes a liquid substrate, which can include a liquid containing a tobacco-containing substance having volatile tobacco flavoring components, or a liquid containing a non-tobacco substance. The liquid substrate can include water, a medicinal liquid, a solvent, ethanol, a plant extract, a flavoring, a flavoring agent, or a vitamin mixture, etc. The flavoring can include betel extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but is not limited thereto. The flavoring agent includes components that can provide various flavors or tastes to a user. The vitamin mixture can be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. Based on different properties of the liquid substrate, the aerosol substrate reservoir can be used in different fields, such as medical, electronic aerosol atomization, etc.

[0059] In some embodiments, the body 2 can further include a liquid storage cotton 212 disposed in the storage cavity 111, the liquid storage cotton 212 being used to absorb the liquid substrate and helping to confine the liquid substrate in the liquid storage cotton 212, thereby preventing the liquid substrate from leaking from the storage cavity 111. It should be noted that the liquid storage cotton 212 is optional.

[0060] In some embodiments, the aerosol generating substrates stored in at least two atomizers 21 are different, so that the two atomizers 21 can generate aerosols with different tastes when working. In some embodiments, the aerosol generating substrates stored in all atomizers 21 are the same, so that each atomizer 21 can generate aerosols with the same taste when working.

[0061] As an exemplary embodiment, the atomizing core 211 can include a liquid absorbing element and a heating element disposed on the liquid absorbing element. The liquid absorbing element can be a porous body for guiding the liquid substrate into the atomizing range of the heating element. The heating element is used to heat the atomized aerosol substrate to generate an aerosol. The porous body can be a fiber, such as a cotton fiber, a polypropylene fiber, a polyester fiber, or a nylon fiber, etc. The porous body can be a porous ceramic or a porous metal, and the present application does not limit the structure and composition of the porous body.

[0062] As an exemplary embodiment, the atomizing core 211 can include an ultrasonic element capable of high-frequency vibration under ultrasonic driving, and the atomizing core atomizes the liquid substrate to form an aerosol by ultrasonic vibration. Of course, the atomizing core can also include other elements capable of atomizing the liquid substrate to form an aerosol.

[0063] In some embodiments, the plurality of atomizers 21 can be arranged in the housing 22 in a manner that is visible to the user, for example, in a manner that is visible to the user through the housing 22. Figure 1 The main body 2 further includes a housing 22 in which the plurality of atomizers 21 are accommodated. At least part of the side wall of the housing 22 can be configured to be visually penetrable so that the one or more atomizers 21 therein can be observed. For example, at least part of the side wall of the housing 22 can be made of glass or a transparent injection-molded part. Or for example, a window that is not blocked is provided on the side wall of the housing 22, and the user can touch the one or more atomizers 21 therein through the window. It should be noted that the at least part of the side wall of the housing 22 being visually penetrable is optional but not mandatory.

[0064] In some embodiments, the aerosol-generating device 100 is configured such that, in a use state, only one atomizer 21 or part of the plurality of atomizers 21 can be in fluid communication with the suction port 11 on the mouthpiece 1. The mouthpiece 1 is configured to be rotatable relative to the main body 2, so that by relative rotation between the two, the one or more atomizers 21 in fluid communication with the suction port 11 can be changed, so that the suction taste can be changed, or when the atomizer 21 in fluid communication with the suction port 11 is insufficient in aerosol-generating substrate, the atomizer 21 that is relatively sufficient in aerosol-generating substrate can be changed to be in fluid communication with the suction port 11.

[0065] Further, the mouthpiece 1 includes a base 13 configured to be movable relative to the main body 2 in a longitudinal direction between a first position and a second position. When the base 13 is in the first position, the mouthpiece 1 and the main body 2 are assembled such that the suction port 11 can be in fluid communication with one of the atomizers 21 or part of the plurality of atomizers 21, while preventing the atomizer 21 in fluid communication with the suction port 11 from being changed. When the base 13 is in the second position, the mouthpiece 1 can be rotated relative to the main body 1 in a transverse direction, and the one or more atomizers 21 in fluid communication with the suction port 11 can be changed by relative rotation between the mouthpiece 1 and the main body 2 in the transverse direction.

[0066] As an exemplary embodiment, when the base 13 is in the first position, the mouthpiece 1 is configured to be unable to rotate or move relative to the main body 2 in the transverse direction, so as to prevent the atomizer 21 in fluid communication with the suction port 11 from being changed.

[0067] Alternatively, as an exemplary embodiment, when the base 13 is in the first position, the mouthpiece 1 can rotate or move laterally relative to the body 2. However, the rotation angle or movement stroke of the mouthpiece 1 relative to the body 2 is limited, preventing the switching of one or more atomizers 21 in fluid communication with the inhalation port 11. For example, when the base 13 is in the first position, the mouthpiece 1 can rotate or move laterally between a working position and a locked position. In the working position, the inhalation port 11 is in fluid communication with one of the atomizers 21 or with some of the atomizers 21; in the locked position, the air passage between the inhalation port 11 and all the atomizers 21 is disconnected, thus preventing fluid communication with any of the atomizers 21. When the mouthpiece 1 moves from the locked position to the working position, the inhalation port 11 is once again in fluid communication with one or more of the atomizers 21.

[0068] In some embodiments, reference may be made to Figure 2 , Figure 5 and Figure 6 The mouthpiece 1 includes an operating part 12 having an air inlet 11. The operating part 12 is configured to be operated by a user to drive the base 13 to move longitudinally from a first position to a second position, and to drive the mouthpiece 1 to rotate laterally relative to the body 2 when the base 13 is in the second position, thereby changing one or more atomizers 21 that are in fluid communication with the air inlet 11.

[0069] In some embodiments, reference may be made to Figure 1 and Figure 2 The proximal end of the housing 22 has a longitudinally extending stop edge 2211. When the base 13 is in the first position, the stop edge 2211 is used to interfere laterally with the side edge of the base 13 to prevent the atomizer 21 in fluid communication with the inhalation port 11 from changing. When the base 13 is in the first position, the stop edge 2211 can be positioned close to the side edge of the base 13 to prevent the mouthpiece 1 from rotating or moving laterally relative to the body 2. When the base 13 is in the first position, the stop edge 2211 can have an appropriate gap with the side edge of the base 13, so that the mouthpiece 1 can rotate or move laterally with limited range relative to the body 2, preventing the atomizer 21 in fluid communication with the inhalation port 11 from changing.

[0070] In some embodiments, reference may be made to Figure 1 , Figure 2 and Figure 7The stop edge 2211 includes an annular structure that encloses a surrounding space having a non-circular cross-section. When the base 13 is in the first position, the annular structure is disposed around at least partially the periphery of the base 13, or at least partially the base 13 is received within the surrounding space enclosed by the stop edge 2211, such that at least partially of the side edge of the base 13 is located inside the annular structure, and at least partially of the side edge of the base 13 is shielded by the stop edge 2211. When the base 13 is in the second position, refer to... Figure 4 The side edge of the base 13 is located outside the surrounding space enclosed by the stop edge 2211, so that the mouthpiece 1 can rotate laterally relative to the body 2, thereby changing the atomizer 21 that is in fluid communication with the inhalation port 11.

[0071] The substrate 13 includes a first surface 1311 disposed opposite to the main body 2, and the operating part 12 is disposed on the first surface 1311. In some embodiments, reference can be made to... Figure 1 and Figure 6 The first surface 1311 is generally a planar structure extending laterally, and the stop edge 2211 has a generally uniform longitudinal height. When the base 13 is in the first position, the first surface 1311 is basically flush with the proximal end of the stop edge 2211, so that the first surface 1311 is located inside the annular structure or within the surrounding space enclosed by the stop edge 2211.

[0072] In some embodiments, reference may be made to Figure 1 and Figure 2 The minimum longitudinal height of the stop edge 2211 is greater than or equal to the maximum side edge height of the base 13, so that when the base 13 is in the first position, the stop edge 2211 can cover the side edge of the base 13 in the longitudinal direction, thus hiding the side edge of the base 13. In this embodiment, the first surface 1311 can be a planar structure extending in the transverse direction, and at least a portion of the first surface 1311 can also be an arc-shaped surface or a spherical surface. In this embodiment, the first surface 1311 can be located inside the annular structure, and at least a portion of the first surface 1311 can also protrude beyond the surrounding range of the annular structure and thus be located outside the annular structure. In this embodiment, it is preferable that the stop edge 2211 has a substantially uniform longitudinal height, so that the longitudinal height of the stop edge 2211 is substantially equal at all points.

[0073] In some embodiments, reference may be made to Figure 2 , Figure 5 and Figure 6The side edge of the base 13 includes a first side edge 132 and a second side edge 133, the height of the first side edge 132 is greater than the height of the second side edge 133. The base 13 has a first end portion 1B and a second end portion 2B opposite to each other, and the first side edge 132 and the second side edge 133 extend between the first end portion 1B and the second end portion 2B. The central axis 1A of the operation portion 12 is located between the central axis 2A of the base 13 and the first end portion 1B of the base 13, the first side edge 132 is located at or adjacent to the first end portion 1B, and the second side edge 133 is located at or adjacent to the second end portion 2B.

[0074] Since the central axis 1A of the operation portion 12 is located between the central axis 1B of the base 13 and the first end portion 1B of the base 13, during the movement of the base 13 along the longitudinal direction from the first position to the second position by the user operating the operation portion 12, the first end portion 1B of the base 13 will be tilted relative to the second end portion 2B along the longitudinal direction, so that the base 13 will be tilted as shown in Figure 3 and Figure 4 The side edge of the second end portion 2B and the side edge of the base 13 adjacent to the second end portion 2B have relatively small longitudinal height, i.e., the second side edge 133 has a height smaller than that of the first side edge 132, so that when the base 13 is located at the second position, the first end portion 1B and the second end portion 2B can both be moved out of the transverse interference range of the stop edge 2211, or the first side edge 132 and the second side edge 133 are both out of interference with the stop edge 2211, so that the mouthpiece 1 can be rotated smoothly and not jammed relative to the main body 2, which helps to improve the user's operation fluency of switching the atomizer 21.

[0075] In some embodiments, not shown, the base has a non-uniform thickness, the thickness of the base at the first end portion is greater than the thickness of the base at the second end portion, so that the height of the side edge of the base at the first end portion is greater than the height of the side edge of the base at the second end portion. The base can have a second surface opposite to the first surface. At least part of the second surface can be a slope, and the closer the base corresponding to the slope is to the second end portion, the smaller the thickness of the base can be. The second surface can include stepped surfaces, and the closer the stepped surface is to the second end portion, the smaller the thickness of the corresponding base can be.

[0076] In some embodiments, reference can be made to Figure 5 and Figure 6The base 13 includes a substrate 131 having a first surface 1311 and a second surface 1312 opposite to each other, and the operation portion 12 is disposed on the first surface 1311. An edge of the second surface 1312 is provided with a first ridge 1321, and at least a part of the first side 132 is located on the first ridge 1321.

Preferably, the first ridge 1321 is flush with the side surface of the substrate 131 at the corresponding position, but is not limited thereto.

[0077] The height of the first side 132 is increased by the first ridge 1321, so that the height of the at least part of the first side 132 is greater than the thickness of the substrate 131 and greater than the height of the second side 132. In this embodiment, the substrate 131 can have a relatively uniform thickness, and the thickness of the substrate 131 at the first end 1B can be equal to the thickness of the substrate 131 at the second end 2B, but is not limited thereto.

The first portion, the second portion and the third portion can be an integral structure. In some embodiments, the height of the first ridge 1321 is substantially uniform in the extension direction thereof. For example, the first portion, the second portion and the third portion can have substantially the same height in the longitudinal direction, and the first ridge 1321 can have a uniform height.

[0081] In some embodiments, referring to Figure 5At least a portion of the height of the second side edge 133 is substantially equal to the thickness of the substrate 131 at the location corresponding to the second side edge 133, wherein the thickness of the substrate 131 at a certain point is equal to the longitudinal spacing between the first surface 1311 and the second surface 1312 at that point. In other words, a portion of the side surface of the substrate 131 constitutes at least a portion of the second side edge 133. Figure 5 In the embodiment shown, the side surface of the second end 2B of the substrate 131 constitutes at least a portion of the second side edge 133.

[0082] In some embodiments, reference may be made to Figure 5 The second side edge 133 includes a second protruding ridge 1331 disposed on the edge adjacent to the second surface 1312, and at least a portion of the second side edge 133 is located on the second protruding ridge 1331. The height of at least a portion of the second side edge 133 includes the sum of the height of the second protruding ridge 1331 and the thickness of the substrate 131 at the corresponding location of the second protruding ridge 1331; and the height of the second protruding ridge 1331 is less than the height of the first protruding ridge 1321. In this embodiment, the substrate 131 may have a relatively uniform thickness, but is not limited thereto.

[0083] In such Figure 5 In the illustrated embodiment, the second protrusion 1331 includes a fourth portion and a fifth portion located on opposite sides of the second end 2B, and the fourth and fifth portions may both be disposed adjacent to the second end 2B. The fourth and fifth portions may have the same extending direction and / or extending length in the lateral direction. The fourth and fifth portions may be symmetrically disposed. The portions on the substrate 131 corresponding to the fourth and fifth portions may have equal thickness.

[0084] In some embodiments, reference may be made to Figure 5 The height of the second protruding ridge 1331 gradually decreases along the direction toward the second end 2B of the base 13 to form an inclined surface. Please refer to... Figure 5 The second portion of the first protruding ridge 1321 and the fourth portion of the second protruding ridge 1331 are located on the same side of the second surface 1312, with the fourth portion being taller as it is closer to the second portion. The lateral extension length of the fourth portion along the edge of the second surface 1312 can be less than or equal to the lateral extension length of the second portion along the edge of the second surface 1312. The third portion of the first protruding ridge 1321 and the fifth portion of the second protruding ridge 1331 are located on the same side of the second surface 1312, with the fifth portion being taller as it is closer to the third portion. The lateral extension length of the fifth portion along the edge of the second surface 1312 can be less than or equal to the lateral extension length of the third portion along the edge of the second surface 1312.

[0085] The fourth portion can be connected to the second portion. The third portion can be connected to the fifth portion. The first protrusion 1321 and the second protrusion 1331 can be connected to each other. The first protrusion 1321 and the second protrusion 1331 can be integrally formed. Preferably, the substrate 131, the first protrusion 1321 and the second protrusion 1331 are integrally formed. Preferably, the main body 13 and the operation portion 12 are integrally formed.

[0086] It should be noted that the second protrusion 1331 can have a higher height closer to the first protrusion 1321, which is optional but not necessary. In other embodiments, the second protrusion 1331 can have a uniform height, so that the second protrusion 1331 can have a substantially equal height at different positions.

[0087] In some embodiments, the mouthpiece 1 can comprise an inhalation tube 14, and the inhalation port 11 can be configured to be in fluid communication with one of the atomizers 21 through the inhalation tube 14 when the main body 13 is in the first position. The central axis of the inhalation tube 14 and / or the inhalation port 11 can be arranged in line with the central axis 1A of the operation portion 12. Figure 2

[0088] The aerosol generating device can be configured such that only one of the atomizers 21 can be in fluid communication with the inhalation port 11 when the main body 13 is in the first position, and the central axis of the atomizer 21 can be arranged in line with the central axis of the inhalation tube 14 and / or the inhalation port 11.

[0089] In some embodiments, the main body 13 can be configured to have a non-circular cross section, and the annular structure of the stopper 2211 can enclose a surrounding space having a non-circular cross section. Thus, when the main body 13 is in the first position, the main body 13 having a non-circular cross section is surrounded and limited by the non-circular stopper 2211, so that the main body 13 cannot be rotated relative to the main body 2 to change the atomizer 21 in fluid communication with the inhalation port 11. The non-circular shape can include an elliptical shape, a rectangular shape, a square shape, a triangular shape, a regular pentagonal shape, or a petal shape, etc. Figure 1 In embodiments as shown in

[0090] and Figure 1 , the annular space of the stopper 2211 can have a substantially elliptical or rectangular cross section. The substrate 131 of the main body 13 can have a substantially elliptical or rectangular shape. Preferably, the side of the main body 13 is arranged adjacent to the inner wall of the annular structure when the main body 13 is in the first position. Figure 2

[0091] ​​In some embodiments, the proximal end of the suction tube 14 is connected to the suction port 11, and the distal end of the suction tube 14 is configured to be outside the surrounding space of the stop edge 2211 when the base 13 is in the second position. The distance R0 between the central axis of the suction tube 14 and the central axis 2A of the base 13 satisfies: L-R1≤R0≤L+R1, where L is the minimum distance between the inner walls of the stop edge 2211, and R1 is half the inner diameter of the suction tube 14. This prevents interference between the stop edge 2211 and the suction tube 14 in the lateral direction during the rotation of the mouthpiece 1 relative to the body 2, and also helps to make the body 2 flatter.

[0092] When the inlet 11 is rotated to the middle position between two adjacent atomizers 21 and the drive operation unit 12 is stopped, it can be referred to Figure 9 The stop edge 2211 can support the mouthpiece 1 and keep the mouthpiece 1 in a second position here. The stop edge 2211 can abut against the distal end of the suction pipe 14 or be spaced apart from the distal end of the suction pipe 14.

[0093] In some embodiments, reference may be made to Figure 2 and Figure 4 The nozzle 1 also includes a rotating part 15 disposed on the base 13, the rotating part 15 being rotatably connected to the main body 2, and the nozzle 1 being configured to rotate about the central axis of the rotating part 15 when the base 13 is in the second position.

[0094] The central axis of the rotating part 15 and the central axis 1A of the operating part 12 can be non-collinearly arranged, so that when the nozzle 1 rotates relative to the main body 2, the operating part 12 or the central axis 1A of the operating part 12 can rotate around the central axis of the rotating part 15.

[0095] The central axis of the rotating part 15 can be collinear with the central axis 2A of the base 13. Thus, when the nozzle 1 rotates relative to the main body 2, the operating part 12 or the central axis 1A of the operating part 12 can rotate around the central axis 2A of the base 13.

[0096] In some embodiments, reference may be made to Figure 2 and Figure 4 The main body 2 also includes a support assembly 23 rotatably assembled with the rotating part 15; when the base 13 is in the first position, the support assembly 23 can support the base 13. When the base 13 is in the first position, the support assembly 23 can be spaced apart from the base 13 in the longitudinal direction.

[0097] The support assembly 23 may include a support plate 231, which may have a laterally extending support surface 2311, with the second surface 1312 of the substrate 131 facing the support surface 2311. In some examples, when the substrate 13 is in a first position, the second surface 1312 and the support surface 2311 are parallel to each other, such that the longitudinal spacing between the corresponding points on the second surface 1312 and the support surface 2311 is approximately equal. Both the second surface 1312 and the support surface 2311 may be approximately planar.

[0098] In some embodiments, reference may be made to Figure 2 The support assembly 23 is disposed between the atomizer 21 and the mouthpiece 1. When the base 13 is in the first position, the mouthpiece 1 is indirectly fluidly connected to one of the atomizers 21 through the support assembly 23.

[0099] For example, the support assembly 23 has multiple air channels, which are fluidly connected to multiple atomizers 21 in a one-to-one correspondence. The inlet 11 is configured to be fluidly connected to the atomizer 21 corresponding to one of the air channels when the base 13 is in the first position. The support assembly 23 also includes through holes 2321, a support plate 231, and a sealing member 232 held on the support plate 231. There are multiple through holes 2321, which are disposed on one or more sealing members 232, and the multiple through holes 2321 respectively constitute at least a portion of the multiple air channels. At least a portion of the sealing member 232 is located between the support plate 231 and the mouthpiece 1, and when the base 13 is in the first position, it elastically abuts against the mouthpiece 1 to make the inlet 11 fluidly connected to one of the air channels in a sealed manner.

[0100] Furthermore, you can refer to Figure 2 and Figure 8 The atomizer 21 also includes a liquid cup 214, a sealing plug 215, and an air delivery tube 213. A storage chamber for storing the aerosol generation matrix is ​​located within the liquid cup 214. The sealing plug 215 is positioned near the proximal end of the liquid cup 214 to prevent leakage of the aerosol generation matrix from the proximal end of the liquid cup 214. The sealing plug 215 has a through hole 2151 that is fluidly connected to the air delivery channel. The proximal end of the air delivery tube 213 can be sealed to the sealing plug 215 and is fluidly connected to the through hole 2151. The atomizing core 211 can be disposed inside or outside the air delivery tube 213, and the atomizing core 211 is fluidly connected to the air delivery tube 213. Thus, the aerosol generated at the atomizing core 211 can flow through the air delivery tube 213 into the through hole 2151, then into the air delivery channel, and finally into the inhalation port 11.

[0101] The sealing plug 215 can support the support component 23 in the longitudinal direction.

[0102] The sealing plug 215 can be provided with an airflow passage 2152 fluidly connecting the storage cavity and the through hole 2151, for balancing the air pressure between the storage cavity and the through hole 2151.

[0103] When the base 13 is in the first position, the air guide passage fluidly connecting the air inlet 11, the through hole 2151 of the atomizer 21 and the air guide tube 213 can be coaxially arranged.

[0104] During the process that the base 13 is in the second position and the mouthpiece 1 rotates relative to the main body 2, the support assembly 23 can shield the sealing plug 215 to protect the sealing plug 215 from moving or being pulled out.

[0105] In some embodiments, referring to Figure 7 and Figure 8 , the through hole 2321 on the sealing member 232 includes a first through hole 1C arranged towards the mouthpiece 1, and the outer diameter of the distal end of the air guide tube 14 is smaller than the hole diameter of the first through hole 1C. When the base 13 is in the first position, the distal end of the air guide tube 14 is located in one of the first through holes 1C. Thus, the distal end of the air guide tube 14 is in clearance fit with the wall defining the first through hole 1C to prevent the sealing member 232 from moving longitudinally during the movement of the base 14 from the first position to the second position, and to facilitate the air guide tube 14 and the sealing member 232 to be separated and combined more easily during the movement of the base 13 between the first position and the second position.

[0106] In some embodiments, referring to Figure 5 and Figure 8 , the sealing member 232 includes annular convex ribs 4C arranged at least partially around the first through hole, and the distal end of the air guide tube 14 has a first annular shoulder 141, which is elastically abutted by one of the annular convex ribs 4C when the base 13 is in the first position, so that the annular seal is formed between the air guide tube 14 and the sealing member 232.

[0107] In some embodiments, referring to Figure 7 , the through hole 2321 further includes a second through hole 2C arranged for the atomizer 21, the first through hole 1C and the second through hole 2C are in communication and coaxially arranged, the hole diameter of the first through hole 1C is larger than that of the second through hole 2C, and the sealing member 232 forms a second annular shoulder 3C between the first through hole 1C and the second through hole 2C. When the base 13 is in the first position, the distal end of the air guide tube 14 contacts the second annular shoulder 3C. Alternatively, when the base 13 is in the first position, the distal end of the air guide tube 14 elastically abuts the second annular shoulder 3C, so that the annular seal is formed between the air guide tube 14 and the sealing member 232.

[0108] In some embodiments, reference can be made to Figure 2 When the base 13 is in the first position, the at least one annular protrusion 4C elastically abuts against the second surface 1312, so that an annular seal is formed between the base 13 and the air guiding passage which is not in fluid communication with the air inlet 11.

[0109] In some embodiments, reference can be made to Figure 5 The second surface 1312 is provided with an annular protrusion 16, which is located in one of the first through holes 1C when the base 13 is in the first position, and the outer diameter of the annular protrusion 16 is smaller than the hole diameter of the first through hole 1C. Thus, the annular protrusion 16 is in clearance fit with the wall defining the first through hole 1C, so as to prevent the sealing member 232 from moving in the longitudinal direction during the movement of the base 13 from the first position to the second position, and to facilitate the annular protrusion 16 and the sealing member 232 to be separated and combined more easily during the movement of the base 13 between the first position and the second position.

[0110] In some embodiments, reference can be made to Figure 2 and Figure 7 When the base 13 is in the first position, the annular protrusion 16 contacts the second annular shoulder 3C. Alternatively, when the base 13 is in the first position, the annular protrusion 16 elastically abuts against the second annular shoulder 3C, so that an annular seal is formed between the annular protrusion 16 and the sealing member 232.

[0111] In some embodiments, reference can be made to Figure 7 and Figure 8 The support plate 231 is provided with a liquid accumulation groove 2312, which is located between the stopper 2211 and the sealing member 232. The liquid accumulation groove 2312 can be used to accumulate at least part of the condensed liquid formed by the condensation of the aerosol on the mouthpiece 1.

[0112] Further, the support plate 231 is provided with a longitudinally extending retaining wall 2313, at least a part of the retaining wall 2313 protrudes out of the support surface 2311 towards the mouthpiece 1, and the retaining wall 2313 is annularly arranged around the periphery of the sealing member 232, so that the sealing member 232 can be fixed on the support plate 231. The liquid accumulation groove 2312 is located between the retaining wall 2313 and the stopper 2211.

[0113] In some embodiments, reference can be made to Figure 2 and Figure 8 The support plate 231 is provided with a longitudinally extending positioning wall 2314, and at least a part of the first protrusion 1321 is located between the stopper 2211 and the positioning wall 2314 when the base 13 is in the first position, and preferably the inner side of the first protrusion 1321 is located adjacent to the positioning wall 2314. The corner of the proximal end of the positioning wall 2314 towards the stopper 2211 can be a rounded corner or an inclined corner.

[0114] In some embodiments, reference may be made to Figure 2 , Figure 4 and Figure 8 The aerosol generating device 100 also includes a reset member 3, which acts between the nozzle 1 and the main body 2 to keep the base 13 in a first position. The reset member 3 can also provide a force to cause the distal end of the suction pipe 14 to abut against the seal 232 and cause the seal 232 to undergo elastic deformation, thereby forming a sealing connection between the suction pipe 14 and the seal 232.

[0115] The reset element 3 may include an elastic element, such as a spring or torsion spring. In one embodiment, refer to... Figure 2 The rotating part 15 connects the main body 2 and the mouthpiece 1 via an elastic element. Specifically, the mouthpiece 1 also includes an anti-detachment part 17 disposed on the rotating part 15. A hollow columnar body 233 is disposed on the support plate 231, and at least a portion of the rotating part 15 is rotatably disposed within the columnar body 233. The interior of the columnar body 233 has an anti-detachment protrusion. When the base 13 is in the first position, the anti-detachment part 17 and the anti-detachment protrusion are spaced apart longitudinally. When the base 13 is moved longitudinally from the first position, the anti-detachment part 17 can move to interfere with the anti-detachment protrusion longitudinally. Due to the obstruction of the anti-detachment protrusion, the rotating part 15 cannot be driven by the user to detach from the main body 2 longitudinally. The elastic element may be disposed inside the columnar body 233.

[0116] When it is necessary to rotate the mouthpiece 1 relative to the main body 2, the operating part 12 can first overcome the elastic force of the elastic member and drive the base 13 to move longitudinally from the first position to the second position; then, continue to overcome the elastic force of the elastic member and drive the mouthpiece 1 to rotate at an appropriate angle so that the base 13 and the stop edge 2211 are spatially intersected; then, the mouthpiece 1 can be placed on the stop edge 2211, so that the stop edge 2211 supports the mouthpiece 1 longitudinally, thereby overcoming the longitudinal elastic force through the longitudinal support of the mouthpiece 1 by the stop edge 2211. After that, the user can mainly overcome the sliding friction between the mouthpiece 1 and the stop edge 2211 to rotate the mouthpiece 1 relative to the main body 2. Finally, the base 13 is returned from the second position to the first position, so that the inhalation port 11 on the mouthpiece 1 is in fluid communication with another atomizer 21.

[0117] In some embodiments, reference may be made to Figure 1 The housing 22 includes a first housing 221 and a second housing 222. A stop 2211 is disposed on the first housing 221. The first housing 221 is connected to the proximal end of the second housing 222. The atomizer 21 can be mainly surrounded by the second housing 222.

[0118] The support assembly 23 can be connected to the first housing 221 such that the support assembly 23 is integrated with the first housing 221. The support plate 231 in the support assembly 23 can be integrally formed with the first housing 221.

[0119] The first housing 221 can be detachably connected to the second housing 222. After the first housing 221 is removed from the second housing 222 or the above-mentioned integrated structure is removed, the atomizer 21 is exposed, so that the atomizer 21 can be taken out and replaced.

[0120] In some embodiments, reference can be made to Figure 2 The aerosol-generating device 100 further includes a power supply assembly 4 disposed in the housing 22. The power supply assembly 4 is electrically connected to the atomizer 21 in fluid communication with the air inlet 11 to provide power for the atomizer 21 to generate aerosol. The power supply assembly 4 can include a power source. The power source can include any suitable battery. For example, the power source can include a lithium battery. Alternatively, for example, the power source can include a rechargeable battery. Alternatively, for example, the power source can include a disposable battery. The power supply assembly 4 can further include a circuit board electrically connected to the power source for controlling the power output of the power source.

[0121] It should be noted that the central axis 2A of the base 13 in any of the above embodiments can be arranged in line with the barycentric line of the base 13, or can be arranged non-in-line with the barycentric line of the base 13.

[0122] It should be noted that the central axis 1A of the operation portion 12 in any of the above embodiments can be arranged in line with the barycentric line of the operation portion 12, or can be arranged non-in-line with the barycentric line of the operation portion 12.

[0123] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification, and further, for those skilled in the art, can be improved or changed according to the above description, and all these improvements and changes should belong to the protection scope of the claims attached to the present application.
