Description

Technical Field

[0001] This application relates to the field of atomization device technology, and in particular to an aerosol generating device. Background Technology

[0002] Aerosol generators heat the aerosol-generating matrix in the fuel tank, turning it into an aerosol for users to inhale. Typically, the atomizing core component in an aerosol generator comes into contact with the aerosol-generating matrix, which can easily lead to matrix deterioration or leakage. Current separation technologies for the atomizing core component and aerosol-generating matrix mostly involve one-time removal, meaning they cannot be separated again after removal, or they require additional toggle switches for separation, making the internal structure of the aerosol generator cumbersome and prone to malfunction. Summary of the Invention

[0003] Therefore, it is necessary to address the problem that most current separation technologies for atomizing core components and aerosol generation matrix involve one-time disassembly, which prevents them from being separated once removed, or the addition of a toggle switch to achieve separation, which makes the internal structure of the aerosol generation device cumbersome and prone to malfunction. In this regard, we need to provide an aerosol generation device.

[0004] An aerosol generating apparatus, comprising:

[0005] The housing assembly includes a housing body and a flow guide connected to the inner wall of the housing body, the flow guide having a through channel and an air intake structure communicating with the channel;

[0006] The atomizing core assembly passes through the channel and is connected to the flow guide;

[0007] A first seal is disposed between the flow guide and the housing body to form a liquid storage cavity surrounding the outer periphery of the channel. One of the flow guide and the first seal rotates relative to the other around the outer periphery of the channel so that the first seal exposes or blocks the air intake structure.

[0008] In one embodiment, along the height direction of the aerosol generating device, the outer shell body includes an upper shell and a middle shell, the inner wall of the upper shell is connected to the flow guide, the middle shell surrounds the outer periphery of the flow guide and is connected to the upper shell, the first sealing member is disposed between the flow guide and the middle shell, and the first sealing member, the upper shell and the middle shell together constitute the liquid storage cavity;

[0009] The middle shell is rotatably connected to one of the upper shell and the first sealing element.

[0010] In one embodiment, the aerosol generating device further includes a second seal disposed between the upper shell and the middle shell.

[0011] In one embodiment, the upper shell is provided with a first guide portion, and the middle shell is provided with a second guide portion that cooperates with the first guide portion. When the upper shell rotates relative to the middle shell, the flow guide rotates relative to the first seal, and the upper shell moves closer to or further away from the middle shell under the action of the first guide portion and the second guide portion, so as to compress or restore the volume of the liquid storage cavity.

[0012] In one embodiment, one of the first guide portion and the second guide portion is configured as a groove and the other is configured as a protrusion, the groove being disposed around the periphery of the channel and extending along the height direction of the aerosol generating device.

[0013] In one embodiment, the atomizing core assembly includes a liquid-guiding cotton, a support body, and a heating element. The support body is snapped into the channel of the flow guide. The outer peripheral surface of the support body has a first gap with the inner peripheral surface of the flow guide. The support body has a hollow portion communicating with the channel and a first opening communicating with the hollow portion. The first opening communicates with an air intake structure. The liquid-guiding cotton is located inside the hollow portion. The first opening is used to communicate with the air intake structure when the upper shell is close to the middle shell.

[0014] In one embodiment, the volume of the liquid-guiding cotton is V, the height of the portion of the support located within the first gap is H, the radius of the inner circumferential surface of the guide member is R1 along the radial direction of the aerosol generating device, the radius of the outer circumferential surface of the support is R2, the radius of the inner circumferential surface of the upper shell is R3, and the distance by which the upper shell approaches the middle shell along the height direction of the aerosol generating device is h, satisfying: .

[0015] In one embodiment, the upper shell includes a first stepped portion, and the middle shell includes a second stepped portion fitted within the first stepped portion. The first stepped portion has a first surface and an outer peripheral surface connected together, and the second stepped portion has a second surface and an inner peripheral surface connected together. The outer peripheral surface is provided with a first guide portion, and the inner peripheral surface is provided with a second guide portion. When the upper shell approaches the middle shell, the first surface gradually moves closer to the second surface, and when the upper shell moves away from the middle shell, the first surface gradually moves away from the second surface.

[0016] In one embodiment, when the upper shell is rotatably connected to the middle shell, one of the upper shell and the middle shell is provided with a second opening extending through its own thickness direction.

[0017] In one embodiment, the first seal comprises a seal body and a shielding structure connected together. The seal body is disposed between the flow guide and the outer shell body, and the shielding structure is disposed on the side of the seal body facing the liquid storage cavity. When the flow guide and the first seal rotate relative to each other, the shielding structure is used to expose or block the air intake structure.

[0018] The aforementioned aerosol generating device uses a flow guide to discharge the atomized aerosol generating matrix, and a storage chamber to store the aerosol generating matrix. The flow guide can be rotated relative to the first seal to the open position, exposing the air intake structure on the flow guide and thus connecting the air intake structure with the storage chamber. The aerosol generating matrix passes through the air intake structure and enters the atomizing core assembly through the channel of the flow guide. The flow guide can then be rotated again relative to the first seal to the locked position, blocking the air intake structure on the flow guide and isolating it from the storage chamber. This prevents the aerosol generating matrix from entering the atomizing core assembly, achieving separation between the aerosol generating matrix and the atomizing core assembly. Therefore, the aerosol generating device of this application allows for multiple switching between the states of the atomizing core assembly and the aerosol generating matrix, achieving multiple separations or contacts without the need for additional components. This simplifies the internal structure of the aerosol generating device and makes its control more sustainable and flexible. Attached Figure Description

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] Please see Figure 1 This application provides an aerosol generating apparatus 100. Please refer to [link / reference needed]. Figure 2 The aerosol generating device 100 includes a housing assembly, an atomizing core assembly 6, and a first sealing element 71. The housing assembly includes a housing body and a flow guide 5 connected to each other. The flow guide 5 has a through channel 51 and an air intake structure 52 communicating with the channel 51. The atomizing core assembly 6 passes through the channel 51 and is connected to the flow guide 5. (See also...) Figure 4 A first seal 71 is disposed between the guide member 5 and the outer casing to surround a liquid storage cavity 81 on the outer periphery of the channel. One of the guide member 5 and the first seal 71 rotates relative to the other around the outer periphery of the channel 51, thereby exposing or blocking the air intake structure 52, thus connecting or isolating the air intake structure 52 from the liquid storage cavity 81. The liquid storage cavity 81 stores the aerosol generating matrix. The aerosol generating device 100 has an open position U where the aerosol generating matrix and the atomizing core assembly 6 are in contact, and a locked position L where they are separated. When the guide member 5 rotates relative to the first seal 71 to the open position U, the aerosol generating matrix enters the atomizing core assembly 6 in the guide member 5 through the air intake structure 52. The atomizing core assembly 6 heats the aerosol generating matrix to generate aerosol, which is then absorbed by the user through the guide member 5. When the guide member 5 rotates relative to the first seal member 71 to the locked position L, the first seal member 71 isolates the atomizing core assembly 6 and the liquid storage chamber 81, thereby separating the aerosol generating matrix and the atomizing core assembly. Thus, by switching between the open position U and the locked position L, the aerosol generating device 100 can be in different states, allowing for repeated separation and contact. Furthermore, the aerosol generating device 100 of this application does not have a separate switching component, which simplifies the internal structure of the aerosol generating device 100, improves the space utilization of the aerosol generating device 100, and reduces the likelihood of malfunctions.

[0044] The relative rotation can be achieved in the following ways, but is not limited to: when the user uses the aerosol generating device 100, the first sealing member 71 is fixedly connected between the flow guide 5 and the outer shell body. The user rotates the outer shell body, causing the flow guide 5 to rotate relative to the first sealing member 71. Alternatively, the user rotates the first sealing member 71, causing the first sealing member 71 to rotate relative to the flow guide 5. The embodiments of this application are not limited to the ways in which the outer shell body and the flow guide 5 rotate.

[0045] The structure of the outer casing will be described below with specific embodiments: Please refer to Figure 1 The outer casing includes an upper shell 1, a middle shell 2, an outer tube 3, and a bottom cover 4. Along the height direction of the aerosol generating device 100, the top of the upper shell 1 has an outlet that communicates with the channel 51 of the guide member 5. The guide member 5 extends downwards from the top of the upper shell 1 toward the interior of the aerosol generating device 100, and symmetrical air inlet structures 52 are provided on both sides of the guide member 5. The air inlet structure 52 can be an air inlet hole or an air inlet slot, etc.

[0046] Please see Figure 4 The top of the upper shell 1 is fixedly connected to the flow guide 5, and the bottom is spaced apart on the outer periphery of the flow guide 5. The bottom of the upper shell 1 extends downward in a divergent manner away from the flow guide 5. The middle shell 2 is located on the outer periphery of the flow guide 5 and connected to the bottom of the upper shell 1. The first sealing member 71 is located between the flow guide 5 and the middle shell 2. The first sealing member 71, the upper shell 1, and the middle shell 2 together constitute the liquid storage cavity 81.

[0047] In one example, the upper shell 1 is fixedly connected to the middle shell 2, and the first seal 71 is rotatably connected to the middle shell 2. The user rotates the first seal 71, causing it to rotate relative to the guide member 5. Preferably, in another example, the upper shell 1 is rotatably connected to the middle shell 2, and the upper shell 1 drives the guide member 5 to rotate relative to the middle shell 2. Adding the middle shell 2 reduces friction between the upper shell 1 and the first seal 71 compared to direct contact rotation, thus reducing rotational resistance and allowing the user to rotate the aerosol generating device 100 more flexibly and easily.

[0048] Please see Figure 6 The degree to which the atomizing core component 6 is filled with the aerosol generating matrix affects whether the amount of aerosol generating matrix is ​​sufficient. A fast aerosol generating matrix flow rate ensures that the amount of aerosol generating matrix in each atomization by the atomizing core component 6 is sufficient. A slow aerosol generating matrix flow rate will result in the atomizing core component 6 not having enough aerosol generating matrix for atomization, leading to less aerosol production, scorching, and less aerosol causing an increase in air volume, making the aerosol weaker and affecting the user's taste.

[0049] In some embodiments, the upper shell 1 is provided with a first guide portion, and the middle shell 2 is provided with a second guide portion that cooperates with the first guide portion. When the upper shell 1 rotates relative to the middle shell 2, under the action of the first and second guide portions, the upper shell 1 moves closer to or further away from the middle shell 2 to compress or restore the volume of the liquid storage chamber 81, while exposing or blocking the air intake structure 52 with the first sealing member 71. Thus, when the air intake structure 52 is exposed, the aerosol generating matrix in the liquid storage chamber 81 can be quickly pressed into the atomizing core assembly 6, rapidly guiding the aerosol generating matrix, ensuring the atomization amount of the aerosol generating matrix, increasing the aerosol content, and reducing scorching and aerosol dilution that affect the user's taste.

[0050] In some embodiments, one of the first guide portion and the second guide portion is configured as a groove 12, and the other is configured as a protrusion 23. The groove 12 is disposed around the periphery of the channel and extends along the height direction of the channel. The rotation structure of the protrusion 23 and the groove 12 is simple and easy to operate. For example, the protrusion 23 can be a block protrusion, a circular protrusion, a conical protrusion, or a strip protrusion, etc. Correspondingly, the groove 12 can be a square groove, a cylindrical groove, a conical groove, or a strip groove, etc., which can be structures that cooperate with the formation of the protrusion 23. The number of protrusions 23 and grooves 12 can be one or more, and this embodiment does not specifically limit this.

[0051] The placement of the protrusion 23 and the groove 12 can be arranged in several ways, but is not limited to: For example, with the upper shell 1 having the groove 12 and the middle shell 2 having the protrusion 23, the groove 12 is located on the bottom surface of the upper shell 1, and the protrusion 23 is located on the top surface of the middle shell 2. Alternatively, the groove 12 is located on the outer peripheral surface 133 of the upper shell 1, and the protrusion 23 is located on the inner peripheral surface 243 of the middle shell 2. Or, in another arrangement, the groove 12 is located on the inner peripheral surface 243 of the upper shell 1, and the protrusion 23 is located on the outer peripheral surface 133 of the middle shell 2.

[0052] Please see Figure 10 and Figure 11 Preferably, in some embodiments, the outer peripheral surface 133 of the upper shell 1 is provided with a groove 12, and the inner peripheral surface 243 of the middle shell 2 is provided with a protrusion 23, so that the middle shell 2 is located on the outer periphery of the upper shell 1, which is beneficial to improving the appearance and decoration of the aerosol generating device 100.

[0053] Please see Figure 10In some embodiments, along the height direction of the aerosol generating device 100, the groove 12 on the outer peripheral surface 133 of the upper shell 1 gradually decreases. The groove 12 has a first end 121 and a second end 122 along its own extending direction, with the first end 121 being lower than the second end 122. The protrusion 23 moves along the groove 12 toward the first end 121 or the second end 122, causing the upper shell 1 to descend or rise relative to the middle shell 2, while the guide member 5 rotates to expose or block the air intake structure 52. In other words, when the protrusion 23 is located at the first end 121 of the groove 12, the aerosol generating device 100 is in the open position U, and the aerosol generating matrix is ​​in contact with the atomizing core assembly 6; when the protrusion 23 is located at the second end 122 of the groove 12, the aerosol generating device 100 is in the locked position L, and the aerosol generating matrix is ​​separated from the atomizing core assembly 6.

[0054] As the upper shell 1 rotates, it descends or rises to compress and restore the volume of the liquid storage chamber 81. Specifically, when the user rotates the upper shell 1 to switch it from the locked position L to the open position U, the protrusion 23 moves along the groove 12 from the second end 122 toward the first end 121. The upper shell 1 rotates relative to the middle shell 2 and descends simultaneously. Driven by the upper shell 1, the guide member 5 rotates relative to the first seal 71. The air intake structure 52 on the guide member 5 is offset from the first seal 71, exposing the air intake structure 52. The height of the liquid storage chamber 81 decreases, and the volume compression allows the aerosol generation matrix to be quickly pressed from the air intake structure 52 into the atomizing core assembly 6. The user can use the aerosol generation device 100 immediately without waiting.

[0055] When the user rotates the upper shell 1 to switch it from the open position U to the locked position L, the protrusion 23 moves along the groove 12 from the first end 121 towards the second end 122. The upper shell 1 rotates relative to the middle shell 2 and rises simultaneously. Driven by the upper shell 1, the guide member 5 rotates relative to the first seal 71. The air intake structure 52 on the guide member 5 coincides with the first seal 71, and the air intake structure 52 is blocked by the first seal 71, realizing the separation of the atomizing core assembly 6 and the aerosol atomizing matrix, reducing the leakage of the aerosol atomizing matrix. At the same time, the height of the liquid storage chamber 81 increases, and its volume recovers, preparing for the next rapid flow of aerosol atomizing matrix.

[0056] Please see Figure 10 The groove 12 of the upper shell 1 does not exceed half of the outer peripheral surface 133 of the upper shell 1 and is provided with a stop, so that the relative movement between the upper shell 1 and the middle shell 2 is less than 180°, so that when the guide 5 is rotated to the open state U, the air intake structure 52 is fully exposed and will not rotate excessively.

[0057] Please see Figure 7In some embodiments, the upper shell 1 includes a first stepped portion 13, and the middle shell 2 includes a second stepped portion 24. The first stepped portion 13 has a first surface 132 and an outer peripheral surface 133 connected together, and the second stepped portion 24 has a second surface 242 and an inner peripheral surface 243 connected together. When the protrusion 23 slides along the groove 12 toward the first end 121, the first surface 132 gradually approaches the second surface 242; when the protrusion 23 slides along the groove 12 toward the second end 122, the first surface 132 gradually moves away from the second surface 242. In other words, when the aerosol generating device 100 is in the open position, the protrusion 23 is located at the first end 121, and the first surface 132 is in contact with the second surface 242; when the aerosol generating device 100 is in the locked state, the protrusion 23 is located at the second end 122, and there is a gap between the first surface 132 and the second surface 242. That is, users can determine whether the aerosol generating device 100 is turned on by observing the contact state between the first surface 132 and the second surface 242 from the outside of the aerosol generating device 100, which is more intuitive and effective.

[0058] In some embodiments, please refer to Figure 7 The first stepped portion 13 of the upper shell 1 also includes a first outer surface 131 and a third surface 134 connected to each other. The first surface 132 is connected between the first outer surface 131 and the outer peripheral surface 133, and the third surface 134 is connected to the outer peripheral surface 133. The outer peripheral surface 133 is provided with a groove 12.

[0059] The middle shell 2 is a hollow columnar structure. In some embodiments, the second stepped portion 24 of the middle shell 2 further includes a second outer surface 241, a fourth surface 244, and a fifth surface 245 connected together. The second surface 242 connects the second outer surface 241 and the inner peripheral surface 243, and the fourth surface 244 connects the fifth surface 245 and the inner peripheral surface 243. The inner peripheral surface 243 is provided with a protrusion 23.

[0060] Please see Figure 11 Along the radial direction of the middle shell 2, a liquid injection structure 22 is provided penetrating the second outer surface 241 and the inner circumferential surface 243. The liquid injection structure 22 can be a liquid injection hole or a liquid injection groove, etc., for injecting the aerosol generation matrix into the liquid storage cavity 81. Please refer to Figure 9 The aerosol generating device 100 also includes a third seal 74, which is used to seal the liquid injection structure 22.

[0061] Please see Figure 7 When the aerosol generating device 100 is in the locked state, the upper shell 1 remains stationary relative to the middle shell 2. The outer peripheral surface 133 of the first step portion 13 is connected to the inner peripheral surface 243 of the second step portion 24. The first surface 132 of the first step portion 13 and the second surface 242 of the second step portion 24 have a first gap. The third surface 134 of the first step portion 13 and the fourth surface 244 of the second step portion 24 have a second gap. The first gap is equal to the second gap.

[0062] Please see Figure 7 When the aerosol generating device 100 is in the open position U, the upper shell 1 rotates and descends relative to the middle shell 2. The first surface 132 of the first step portion 13 and the second surface 242 of the second step portion 24 are connected, and the third surface 134 of the first step portion 13 and the fourth surface 244 of the second step portion 24 are connected. At the same time, the first outer surface 131 of the first step portion 13 and the second outer surface 241 of the second step portion 24 are connected, and the third surface 134 of the first step portion 13 is also connected to the fifth surface 245 of the second step portion 24.

[0063] Please see Figure 2 and Figure 7 In some embodiments, the aerosol generating device 100 further includes a second sealing element 72, which is disposed between the upper shell 1 and the middle shell 2. A fixing groove 73 is also provided on the side of the upper shell 1 or the middle shell 2 facing each other. The second sealing element 72 is tightly clamped within the fixing groove 73 to ensure an interference fit between the upper shell 1 and the middle shell 2, thereby improving the sealing performance of the aerosol generating device 100 while ensuring that the upper shell 1 can rotate.

[0064] Preferably, a fixing groove 73 is provided on the outer peripheral surface 133 of the upper shell 1. In the case of interference fit, the contact between each groove surface of the upper shell 1 in the fixing groove 73 and the second seal 72 increases the connection stability between the upper shell 1 and the second seal 72, while ensuring sealing performance, connection stability and rotation flexibility.

[0065] Please see Figure 11 In some embodiments, the middle shell 2 is further provided with a second opening 21 extending through its own thickness direction, and the second opening 21 is located near the protrusion 23. The second opening 21 is provided to buffer the compressive stress when the protrusion 23 is engaged in the groove 12, so that the protrusion 23 can be engaged in the groove 12 freely, ensuring that the relative movement of the upper shell 1 and the middle shell 2 can switch from the locked position L to the open position U, and can also switch back from the open position U to the locked position L.

[0066] For example, the second opening 21 can be provided in one, two or three quantities, and further, the second opening 21 can be provided on the left or right side, or the top or bottom side of the protrusion 23.

[0067] Please see Figure 10 The outer surface of the upper shell 1 is provided with a positioning structure 11. When the protrusion 23 is located at the second end 122 of the groove 12, the aerosol generating device 100 is in a state where the atomizing core component 6 and the aerosol matrix are isolated from each other, and the positioning structure 11 is aligned with the second opening 21 at this time. The positioning structure 11 serves as a visual alignment, making it easy for the user to observe whether the aerosol generating device 100 is in the above-mentioned state.

[0068] For example, the positioning structure 11 may be a groove 12 structure or a protrusion 23 structure, or a structure that is easy for the user to identify. The positioning structure 11 may be in the shape of a dot, a block, a strip, etc., and the number of positioning structures 11 may be one, two, or three, etc.

[0069] Please see Figure 10 Preferably, the second openings 21 are arranged in pairs, respectively located on the left and right sides of the protrusion 23 along the circumferential direction of the middle shell 2. The paired second openings 21 penetrate the second outer surface 241, the second surface 242, and the inner circumferential surface 243 of the second step portion 24. The positioning structure 11 is a pair of groove structures, spaced apart from each other, and the groove structures penetrate the first outer surface 131 and the first surface 132 of the first step portion 13.

[0070] Please see Figure 3 When the aerosol generating device 100 is in the locked position L, along the height direction of the aerosol generating device 100, the groove structure is located directly above the second opening 21, and each groove structure is aligned with one of the second openings 21 in the height direction. Along the height direction of the aerosol generating device 100, the groove structure has a first side and a second side arranged vertically opposite each other, and the second opening 21 has a third side and a fourth side arranged vertically opposite each other. At this time, the first side and the third side are axially aligned, and the second side and the fourth side are axially aligned. Therefore, whether the aerosol generating device 100 is in the locked position L can be determined by whether the positioning structure 11 is aligned with the second opening 21.

[0071] Please see Figure 2 The outer tube 3 of the aerosol generating device 100 is fitted onto the outer periphery of the middle shell 2, and the bottom cover 4 is connected to the bottom end of the outer tube 3 to seal it. The outer tube 3 is a metal tube with a receiving cavity to house the first sealing element 71, as well as the atomizing core assembly 6, absorbent cotton 82, battery cell 83, and bottom cover silicone plug 84. The bottom cover silicone plug 84 is sealed to the outer tube 3 and located on the side closest to the bottom cover 4.

The radius R2 of the outer peripheral surface 133 of the support body refers to the radius of the outer peripheral surface of the atomizing tube 623, and the height difference between the first end 121 and the second end 122 of the groove 12 of the upper shell 1 is calculated accordingly.

[0076] Please see Figure 5 Specifically, the atomizing core stopper 622 includes a cap 622a and a tube 622b, which together form a first hollow portion 622c. An air guide tube 621 passes through the first hollow portion 622c. The top end of the cap 622a is fixedly connected to the top end of the tube 622b, and the bottom end of the cap 622a extends in a divergent manner toward the bottom end of the tube 622b. A second gap 622d exists between the bottom end of the cap 622a and the tube 622b.

[0077] Please see Figure 5 The atomizing tube 623 has a second hollow portion 623a, and the top end of the atomizing tube 623 is snapped into a second gap 622d. A liquid-guiding cotton 61 is located at the bottom end of the tube portion 622b and within the second hollow portion 623a of the atomizing tube 623. A plastic support 624 is located at the bottom end of the liquid-guiding cotton 61 and also within the second hollow portion 623a of the atomizing tube 623.

[0078] Please see Figure 5 The plastic bracket 624 has a pipe extending through its height and a third hollow portion 624a, with the pipe and the third hollow portion 624a spaced apart. An annular groove is provided around the bottom of the plastic bracket 624 surrounding the third hollow portion 624a.

[0079] Please see Figure 5 The liquid-absorbing cotton 61 has a fourth hollow portion 61a, which is connected to the third hollow portion 624a. The heating mesh 632 is distributed along the inner circumference of the fourth hollow portion 61a.

[0080] Please see Figure 5 The absorbent cotton 82 is located at the bottom of the first sealing element 71 to prevent the aerosol generation matrix from seeping downwards. The absorbent cotton 82 has a notch and can be in the shape of an arc or a right angle for ventilation.

[0081] Please see Figure 5 In some embodiments, the first seal 71 includes a seal body 711 and a shielding structure 712 connected to each other. The shielding structure 712 is disposed on the top of the seal body 711. The outline dimension of the shielding structure 712 is larger than the outline dimension of the air intake structure 52. When the flow guiding mechanism rotates relative to the first seal 71, the shielding structure 712 is used to expose or block the air intake structure 52.

[0082] Please see Figure 5 The first sealing element 71 is connected between the flow guide 5, the middle shell 2, the outer tube 3, and the absorbent cotton 82. The sealing element body 711 has a fifth hollow portion 713, through which the flow guide 5 passes. The plastic bracket 624 is interference-fitted with the fifth hollow portion 713.

[0083] Please see Figure 5 The fifth hollow part 713 is provided with several raised ribs 714 on the contact surface with the guide member 5. The raised ribs 714 and the outer surface, bottom surface and inner circumferential surface 243 of the tube wall of the guide member 5 are press-fitted and sealed, so that the aerosol generation matrix can not only enter the liquid guiding cotton 61, but also enter and be stored in the gap between the guide member 5 and the atomizing tube 623.

[0084] Please see Figure 5 The contact surfaces of the first seal 71 with the middle shell 2 and the outer tube 3 are also provided with several raised ribs 714 for sealing. Please refer to [link / reference]. Figure 9The bottom end of the first sealing element 71 is provided with a ventilation groove 715 on the side facing the absorbent cotton 82 for ventilation.

[0085] The specific operating principle of the aerosol generating device 100 of this application will be described below: The user rotates the upper shell 1 of the aerosol generating device 100, causing the aerosol generating device 100 to change from the locked position L to the open position U. The upper shell 1 of the aerosol generating device 100 descends, and the guide member 5 rotates relative to the shielding structure 712 of the first sealing member 71, so as to expose the air intake structure 52 on the guide member 5 to the liquid storage chamber 81. At the same time, the volume of the liquid storage chamber 81 is compressed, so that the aerosol generating matrix is ​​quickly pressed into the gap between the atomizing tube 623 and the guide member 5, and at the same time, the aerosol generating matrix enters the liquid guiding cotton 61 through the air intake structure 52 and the first opening 65 of the atomizing tube 623.

[0086] Next, the user draws in the aerosol generating device 100, causing the external airflow of the aerosol generating device 100 to enter the receiving cavity of the outer tube 3 through the air inlet holes of the bottom cover 4 and the bottom cover silicone plug 84, and pass through the gap between the outer tube 3 and the battery cell 83 to enter the absorbent cotton 82, and then enter the ventilation groove 715 of the first sealing member 71, the fifth hollow part 713, the third hollow part 624a of the plastic bracket 624, and the fourth hollow part 61a of the liquid guiding cotton 61 to heat the aerosol generating matrix and atomize it, generating aerosol that is discharged through the air guide tube 621 and absorbed by the user.

[0087] After use, the user rotates the upper shell 1 again, causing the aerosol generator 100 to change from the open position U to the locked position L. The upper shell 1 of the aerosol generator 100 rises, and the guide member 5 rotates in the opposite direction to the blocking structure 712 of the first sealing member 71, blocking the air intake structure 52 on the guide member 5 and thus isolating the liquid storage chamber 81. Simultaneously, the volume of the liquid storage chamber 81 returns to normal, preparing for the user's next aerosol extraction.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
