Description

Technical Field

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

[0002] An aerosol-generating device is a device that generates an aerosol-generating article when heated but not combusted, generating an aerosol for inhalation by the user. The device typically includes a receiving cavity for at least partially accommodating the aerosol-generating article and an inlet for inserting the aerosol-generating article into the receiving cavity. One existing device also includes an end cap and a shielding cover movably disposed on the end cap. The inlet is formed on the end cap, and the shielding cover is exposed on the end cap, allowing the user to directly operate the shielding cover to move the shielding cover, thereby opening or blocking the inlet.

[0003] However, the maximum temperature at which the aerosol generating device heats the aerosol generating product is higher than 200°C. After the aerosol generating product is pulled out, the temperature at the entrance is relatively high. If the user directly drives the shielding cover provided on the end cover to cover the entrance with his hand, the entrance may easily face the user's hand during the driving process, thereby easily causing discomfort to the user. Utility Model Content

[0004] The purpose of the present application is to provide an aerosol generating device that can prevent the high temperature at the first inlet from causing a burning sensation and discomfort to the user.

[0005] At least one embodiment of the present application provides an aerosol generating device, comprising:

[0006] A housing is provided with a receiving cavity therein, and a display slot is provided on the housing;

[0007] a movable cover, movably disposed inside the housing;

[0008] an end cap connected to the housing, the end cap being provided with a first inlet for at least a portion of the aerosol-generating article to enter and be retained in the accommodating cavity; and

[0009] a drive assembly comprising an operating portion arranged in linkage with the movable cover, wherein at least a portion of the operating portion is exposed through the display slot, and the operating portion is configured to be operated by a user to drive the movable cover to move relative to the end cover between a first position and a second position;

[0010] The movable cover is configured to close the first entrance when located at the first position, and to open the first entrance and be blocked by the end cover when located at the second position.

[0011] As an example, the operation portion is configured to rotate about a longitudinal axis thereof under operation of a user, the longitudinal axis being parallel to a central axis of the accommodation cavity.

[0012] As an example, the operation portion is configured to rotate under operation of a user and drive the movable cover to move linearly.

[0013] As an example, the aerosol generating device further comprises a first support, the movable cover is disposed between the first support and the end cover, and a linear guide rail is disposed on the first support, the movable cover being slidably connected to the linear guide rail to move along the linear guide rail.

[0014] As an example, the drive assembly further comprises a transmission mechanism connected to the operation portion, the transmission mechanism being rotatably connected to the movable cover.

[0015] As an example, the transmission mechanism comprises a first drive arm, a second drive arm, and a sliding groove between the first drive arm and the second drive arm.

[0016] The movable cover comprises a connecting portion rotatably disposed in the sliding groove, and the transmission mechanism is configured to drive the movable cover to move to the second position by the first drive arm when the operation portion is rotated in a forward direction, and drive the movable cover to move to the first position by the second drive arm when the operation portion is rotated in a reverse direction.

[0017] As an example, one end of the sliding groove is closed, and the other end is open.

[0018] As an example, a stop portion is further disposed on the first support, the transmission mechanism is configured to be stopped by the linear guide rail when driving the movable cover to be located at the first position, and the movable cover is configured to be stopped by the stop portion when being driven to be located at the second position.

[0019] As an example, the aerosol generating device further comprises a damping member disposed on the first support or the end cover, and the damping member is connected to the movable cover to provide damping when the movable cover moves.

[0020] As an example, a first fixing column is disposed on the first support or the end cover, and a second fixing column is disposed on the movable cover.

[0021] The damping member includes a torsion spring, which includes an elastic body and a first elastic arm and a second elastic arm located at opposite ends of the elastic body. The first elastic arm is rotatably connected to the first fixed column, and the second elastic arm is rotatably connected to the second fixed column. Therefore, during the movement of the movable cover, the first elastic arm rotates around the first fixed column, and the second elastic arm rotates around the second fixed column.

[0022] As an example, the aerosol generating device further includes a detection sensor for detecting the position of the movable cover, a power supply and a heating component for heating the aerosol generating article to generate an aerosol, and the power supply is configured to stop providing electrical power to the heating component when the movable cover is located in a position other than the second position.

[0023] In the aerosol generating device provided in the above embodiments, at least a portion of the operating portion is exposed in the display slot on the shell, and the operating portion can be operated by the user, and then the operating portion can drive the movable cover to move between the first position and the second position under the operation of the user. When the movable cover is in the second position, the first entrance is opened and the movable cover is blocked by the end cover, so that when the user needs to close the first entrance, the user cannot directly operate the movable cover, and can avoid the first entrance because of the need to operate the transmission mechanism, thereby preventing the high temperature at the first entrance from causing discomfort to the user.

[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] The terms "first", "second" and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or suggesting relative importance or implicitly indicating the quantity or order of the indicated technical features. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative position relationship or movement situation between the various components under a certain specific posture (as shown in the accompanying drawings).

For example, a process, method, system, product or equipment that includes a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.

[0045] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0046] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0047] Please refer to Figure 1 and Figure 2 Some embodiments of the present application provide an aerosol generating device 100 , which can be used in conjunction with an aerosol generating article, so that the aerosol generating article generates aerosol.

[0048] An aerosol-generating article may include a mouthpiece, a connecting section, and an aerosol-generating substrate segment capable of generating an aerosol. The connecting section is positioned between the mouthpiece and the aerosol-generating substrate segment and is configured to direct the aerosol toward the mouthpiece. The mouthpiece is positioned to be held in a user's mouth, and the user can inhale the aerosol by sucking on the mouthpiece.

[0049] The aerosol-generating substrate segment of the aerosol-generating article may comprise an aerosol-generating substrate.

[0050] As used herein, the term "aerosol generating substrate" refers to a substrate that can release volatile substances to form an inhalable aerosol. The aerosol generating substrate may include a tobacco-containing material that contains volatile tobacco flavor compounds that are released from a substrate after heating. Specifically, the aerosol generating substrate may be an aerosol generating substrate containing tobacco, preferably an aerosol generating substrate containing solid tobacco. Alternatively, the aerosol generating substrate may include a non-tobacco material. The aerosol generating substrate may also include a liquid substrate stored in the aerosol substrate section. Suitable liquid substrates may include glycerol and propylene glycol. Suitable liquid substrates may also include nicotine, sweeteners, or cooling agents.

[0051] Optionally, the aerosol-generating substrate may contain additional tobacco or non-tobacco volatile flavor compounds that are released upon heating the aerosol-generating substrate. The aerosol-generating substrate may also contain microcapsules, for example, containing additional tobacco or non-tobacco volatile flavor compounds, and such microcapsules may melt during heating of the solid aerosol-generating substrate.

[0052] The aerosol-generating article may be a generally longitudinally extending rod-shaped structure. The mouthpiece may be disposed adjacent to a proximal end of the aerosol-generating article. The aerosol-generating substrate segment may be disposed adjacent to a distal end of the aerosol-generating article.

[0053] It should be noted that the inclusion of a mouthpiece and a connecting segment in the aerosol-generating article is optional and not mandatory. In some embodiments, the aerosol-generating article may only include an aerosol-generating substrate segment capable of generating an aerosol. In such embodiments, the aerosol-generating device may include a mouthpiece assembly for the user to hold in their mouth.

[0054] Please refer to Figure 2 and Figure 6 The aerosol-generating device 100 includes a housing 1. A housing 1 is provided within the housing 1 to receive at least a portion of an aerosol-generating article. In one example, when the aerosol-generating article is combined with the aerosol-generating device 100, the entire aerosol-generating substrate is located within the housing 11.

[0055] Please refer to Figures 2-4 The aerosol generating device 100 includes an end cap 2, and a first inlet 21 is provided on the end cap 2 for at least a portion of the aerosol generating product to enter the accommodating chamber 11. In some embodiments, reference may be made to Figure 2 The accommodating chamber 11 and the first inlet 21 are connected to each other, and the accommodating chamber 11 and the first inlet 21 are arranged longitudinally, so that at least a portion of the aerosol generating product can pass through the first inlet 21 longitudinally and enter the accommodating chamber 11 for retention.

[0056] Please refer to Figure 2 and Figure 4The aerosol-generating device 100 includes a movable cover 3. The movable cover 3 is configured to move relative to the first inlet 21, allowing the movable cover 3 to close or open the first inlet 21. When the movable cover 3 blocks the first inlet 21, the aerosol-generating product cannot enter the accommodating chamber 11 from the outside. The movable cover 3 also prevents dust or foreign matter from entering the accommodating chamber 11. When the movable cover 3 is removed from blocking the first inlet 21, the first inlet 21 is opened, allowing the aerosol-generating product to enter the accommodating chamber 11 from the outside.

[0057] In some embodiments, the movable cover 3 is configured to be movable in a lateral direction, and can close or open the first inlet 21 by moving in the lateral direction.

[0058] Preferably, the movement direction of the movable cover 3 is perpendicular to the arrangement direction of the accommodating cavity 11 and the first inlet 21. Figure 2 and Figure 4 In the illustrated embodiment, the movable cover 3 is configured to be movable in a transverse direction, and the accommodating cavity 11 and the first inlet 21 are arranged in a longitudinal direction.

[0059] Please refer to Figure 1 、 Figure 3 and Figure 4 The aerosol generating device 100 includes a drive assembly 4. The drive assembly 4 is configured to drive the movable cover 3 to move, thereby enabling the movable cover 3 to close or open the first inlet 21. Specifically, the drive assembly 4 includes an operating portion 41, at least partially exposed so as to be operable by a user. The operating portion 41 is interlocked with the movable cover 3, so that the user can drive the movable cover 3 to move relative to the first inlet 21 by actuating the operating portion 41, thereby enabling the movable cover 3 to close or open the first inlet 21.

[0060] More specifically, the user can drive the operating portion 41 to move the movable cover 31 between the first position and the second position relative to the end cover 2. When the movable cover 31 is in the first position, the first inlet 21 is closed; when the movable cover 31 is in the second position, the first inlet 21 is open.

[0061] In some embodiments, reference may be made to Figure 2 The movable cover 3 is movably arranged inside the shell 1, and when the movable cover 3 is located in the second position, the movable cover 3 is blocked by the end cover 2, so that the movable cover 3 is hidden when it is located in the second position, so that the user cannot drive the movable cover 3 to move to the first position by directly operating the movable cover 3.

[0062] You can refer to Figure 1 and Figure 6The housing 1 is provided with a display slot 12, through which at least a portion of the operating portion 41 is exposed. At least a portion of the operating portion 41 is disposed on a side wall of the aerosol generating device 100. Exposing at least a portion of the operating portion 41 through the display slot 12 on the housing 1 prevents the end cap 2 and / or the first inlet 21 thereon from being exposed to the user's hand when the user needs to move the movable cover 3.

[0063] In some embodiments, the operating portion 41 is configured to rotate in response to a user's operation, and the movable cover 3 moves between a first position and a second position in response to the rotation of the operating portion 41. Compared to enabling the operating portion to move laterally within the display slot, enabling the operating portion to rotate within the display slot not only shortens the lateral extension of the display slot but also allows the operating portion to more fully occupy the space of the display slot, thereby reducing the gap between the housing and the operating portion or reducing the idle space within the display slot. This helps improve the surface consistency and aesthetics of the aerosol generating device.

[0064] Furthermore, the operating portion 41 can be configured to rotate around a longitudinal axis passing through it under user operation, with the longitudinal axis being parallel to the central axis of the accommodating chamber 11. This allows the user to easily and single-handedly simultaneously grasp the aerosol generating device 100 and drive the operating portion 41 to rotate. In conventional aerosol generating devices, a movable cover is provided on the end cap. To move the movable cover, the user needs to grasp the aerosol generating device with one hand and use the other hand to actuate the movable cover. Therefore, by exposing at least a portion of the operating portion through the display slot on the housing, the user can also move the movable cover with a single hand.

[0065] The longitudinal axis may be collinear with the central axis of the operating portion 41 , or the longitudinal axis may be non-collinear with the central axis of the operating portion 41 but parallel to each other.

[0066] In some embodiments, the operating portion 41 can drive the movable cover 3 to move in a straight line.

[0067] In order to ensure that the movable cover 3 can move in a straight line, the aerosol generating device 100 may further include a linear guide rail 5 . The movable cover 3 is slidably connected to the linear guide rail 5 and can move along the linear guide rail 5 under the drive of the driving assembly 4 .

[0068] As an example, see Figure 2 The aerosol generating device 100 further includes a first bracket 6 , the movable cover 3 is disposed between the first bracket 5 and the end cover 2 , and at least a portion of the linear guide rail 5 is disposed on the first bracket 6 . At least a portion of the first bracket 6 is located within the housing 1 .

[0069] The first bracket 6 can be connected to the end cover to form an integrated structure, so that the end cover, the movable cover and the first bracket can be connected to the housing as a whole.

[0070] The first bracket 6 may be provided with a second inlet 61, which is arranged corresponding to the first inlet 21 and is located between the first inlet 21 and the accommodating chamber 11. The first inlet 21, the second inlet 61, and the accommodating chamber 11 may be arranged in a longitudinal sequence. At least a portion of the aerosol-generating article must pass through the first inlet 21 and the second inlet 61 in sequence before entering the accommodating chamber 11. When the movable cover 3 is in the first position, at least a portion of the movable cover 3 is located between the first inlet 21 and the second inlet 61, thereby blocking the second inlet 61 and blocking the passage between the first inlet 21 and the accommodating chamber 11 for the aerosol-generating article to pass through.

[0071] The linear guide rail 5 includes a first linear rail 51 and a second linear rail 52. The first linear rail 51 and the second linear rail 52 both extend in a straight line in the transverse direction, and the first linear rail 51 and the second linear rail 52 are parallel to each other. Figure 5 In the embodiment shown, the first linear track 51 and the second linear track 52 are both arranged on the first bracket 6, and the first linear track 51 and the second linear track 52 can be integrally formed with the first bracket 6; based on this, the end cover 2 can be a sheet structure with relatively flat inner and outer surfaces.

[0072] In some embodiments, the driving assembly 4 further includes a transmission mechanism 42 connected to the operating part 41 .

[0073] As an example, one end of the transmission mechanism 42 is rotatably connected to the operating portion 41 , and the other end of the transmission mechanism 42 is rotatably connected to the movable cover 3 , so that when the operating portion 41 rotates, the angle between the transmission mechanism 42 and the operating portion 41 changes.

[0074] Alternatively, as an example, you can refer to Figure 9 The transmission mechanism 42 is fixedly connected to the operating portion 41, so that when the operating portion 41 rotates, the transmission mechanism 42 rotates along with the operating portion 41, but the angle between the operating portion 41 and the transmission mechanism 42 remains unchanged. In this example, the transmission mechanism 42 can be integrally formed with the operating portion 41, but is not limited thereto.

[0075] In some embodiments, the transmission mechanism 42 is rotationally connected to the movable cover 3, so that when the transmission mechanism 42 rotates under the drive of the operating part 41, the transmission mechanism 42 can rotate relative to the movable cover 3, so that the movable cover 3 can move in a straight line under the constraint of the linear guide rail 5.

[0076] In some embodiments, reference may be made to Figure 7 and Figure 8The movable cover 3 includes a body 31 and a connecting portion 32 provided on the body 31. When the movable cover 3 is in the first position, the body 31 closes the first inlet 21, or at least a portion of the body 31 is located between the first inlet 21 and the second inlet 61. The connecting portion 32 is rotatably connected to the transmission mechanism 42.

[0077] There are many ways to realize the rotational connection between the connecting portion 32 and the transmission mechanism 42. For example, the connecting portion 32 and the transmission mechanism 42 can be rotationally connected by a hinge.

[0078] In such Figure 9 and Figure 10 In the illustrated embodiment, the transmission mechanism 42 includes a first drive arm 421, a second drive arm 422, and a slide slot 423 located between the first drive arm 421 and the second drive arm 422. The connecting portion 32 is rotatably disposed in the slide slot 423. The transmission mechanism 42 is configured such that when the operating portion 41 rotates in the forward direction X, the transmission mechanism 4 drives the movable cover 3 to the second position via the first drive arm 421. When the operating portion 3 rotates in the reverse direction, the transmission mechanism 4 drives the movable cover 3 to the first position via the second drive arm 421. During the forward and reverse rotations of the transmission mechanism 4, the connecting portion 32 slides along the slide slot 423 while rotating in the slide slot 423.

[0079] Furthermore, one end of the chute 423 is closed and the other end is open, so during assembly, the connecting portion 32 can be inserted into the chute 423 from the open end.

[0080] In some embodiments, when the movable cover 3 moves from the second position to the first position, the movable cover 3 and / or the driving assembly 4 can be stopped to prevent the movable cover 3 from continuing to move from the first position along the original movement direction. When the movable cover 3 moves from the first position to the second position, the movable cover 3 and / or the driving assembly 4 can be stopped to prevent the movable cover 3 from continuing to move from the second position along the original movement direction.

[0081] For example: you can refer to Figure 3 A stop portion 62 is also provided on the first bracket 6. The transmission mechanism 6 is configured so that when the movable cover 3 is driven to the first position, the transmission mechanism 42 is stopped by the linear guide rail 5. The movable cover 3 is configured so that when it is driven to the second position, the movable cover 3 is stopped by the stop portion 62.

[0082] More specifically, when the movable cover 3 is driven by the transmission mechanism 6 to be located at the first position, the first driving arm 421 of the transmission mechanism 42 can be stopped by the first linear guide rail 51, so that the transmission mechanism 42 cannot continue to rotate in the original rotating direction under the continuous driving of the operation part 41 in the original direction, and thus the movable cover 3 can stop moving at the first position. At this time, the end of the first driving arm 421 can be located between the first linear guide rail 51 and the second linear guide rail 52, and is spaced apart from the second linear guide rail 52.

[0083] The movable cover 3 is provided with a matching part 33 corresponding to the stop part 62, and when the movable cover 3 is driven by the transmission mechanism 4 to be located at the second position, the matching part 33 is stopped by the stop part 62, so that the movable cover 3 cannot continue to move in the original direction under the continuous rotation of the transmission mechanism 4 in the original direction, and thus the movable cover 3 can stop moving at the second position. The stop part 62 can be connected with the second linear guide rail 52. The stop part 62 can be arranged perpendicular to the second linear guide rail 52.

[0084] In some embodiments, the aerosol generating device 100 further comprises a damping member 7 arranged on the first support 6 or the end cover 2, and connected with the movable cover 3 to provide damping when the movable cover 3 moves. Based on the damping, the user can obtain the feeling of operating the driving assembly 4. At the same time, based on the damping, the movable cover 3 can be kept at the first position or the second position when the operation part 41 is not driven, so that the first inlet 21 is maintained in the open or closed state.

[0085] In the embodiments as shown in the drawings, Figures 3-8 In the embodiments as shown in the drawings,

[0086] The above arrangement makes the first elastic arm 72 rotate around the first fixed column 63 or the second elastic arm 73 rotate around the second fixed column 34, which lags behind the linear movement of the movable cover 3, so that the elastic body 71 can be elastically deformed and generate damping during the movement of the movable cover 3. The torsional spring can have the same shape when the movable cover 3 is located at the first position and when the movable cover 3 is located at the second position, or the included angle between the first elastic arm 72 and the second elastic arm 73 is equal.

[0087] During the movement of the movable cover 3, the first elastic arm 72 and the second elastic arm 73 can always be arranged non-collinearly.

[0088] In some embodiments, reference may be made to Figure 3 and Figure 7 The main body 31 of the movable cover 3 includes a first body 311 and a second body 312 arranged in a stepped shape. The second body 312 connects the first body 311 and the connecting portion 32. When the movable cover 3 is in the first position, the first body 311 closes the first inlet 21, or the first body 311 is located between the first inlet 21 and the second inlet 61.

[0089] The second fixing post 34 can be disposed on the second body 312. The second fixing post 34 can include a longitudinally extending columnar portion 341 and a hook portion 342 disposed at the end of the columnar portion 341. The hook portion 342 extends transversely. The end of the second elastic arm 73 is spirally disposed around the columnar portion 341, and the spiral end of the second elastic arm 73 is located between the hook portion and the second body 312. The hook portion 342 can prevent the spiral end of the second elastic arm 73 from detaching from the second fixing post 34. The height of the end surface of the hook portion 342 facing the end cap 2 can be less than or equal to the height of the surface of the first body 311 facing the end cap 2.

[0090] The first fixing column 72 can be set on the first bracket 6, and the first fixing column 72 can support the end cover 3. The end of the first elastic arm 72 is spirally arranged around the first fixing column 72, and the end cover 3 can prevent the spiral end of the first elastic arm 72 from detaching from the second fixing column 34.

[0091] In some embodiments, the Figure 3 As shown, when the movable cover 3 is in the first position, the elastic body 71 is arranged corresponding to the second body 312 of the movable cover 3. In some embodiments, the movable cover 3 may be positioned as shown in FIG. Figure 4 As shown, the movable cover 3 is located at the second position, and the elastic body 71 and the main body 31 of the movable cover 3 are staggered.

[0092] In some embodiments, the drive assembly 4 may be retained on the first bracket 6 .

[0093] For details, please refer to Figure 3 and Figure 4 The transmission mechanism 42 is disposed between the first bracket 6 and the end cover 2 , and the transmission mechanism 42 is configured to be able to rotate in the space between the first bracket 6 and the end cover 2 .

[0094] In such Figures 3-5 In the embodiment shown, the first bracket 6 may include an annular wall 64 and a bottom wall 65 located on the inner side of the annular wall 64, the annular wall 64 is connected to the end cover 2, and a retaining cavity is formed between the end cover 2 and the bottom wall 65, the transmission mechanism 42 is retained in the retaining cavity, and the movable cover 3 can be movably arranged in the retaining cavity.

[0095] You can refer to Figure 6A through hole 651 may be provided on the bottom wall 65 , and a portion of the operating portion 41 is located in the through hole 651 , so that the operating portion 41 is connected to the transmission mechanism 42 located in the holding cavity.

[0096] The first bracket 6 may further include an extension wall 66 disposed in the display slot 12 .

[0097] The operating portion 41 can be rotated around a longitudinal axis passing through the operating portion 41 under the operation of the user, so that the operating portion 41 can more fully occupy the space of the through slot.

[0098] In some embodiments, the linear guide rail 5 is disposed on the bottom wall 65. When the movable cover 3 is slidably connected to the linear guide rail 5, the movable cover 3 can be surrounded by the annular wall 64. At least a portion of the annular wall 64 can be exposed outside the end cover 2 and the housing 1. The linear guide rail 5, the annular wall 64, the bottom wall 65, and the extension wall 66 can be integrally formed.

[0099] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 further includes a heating component 8 and a power source 91 electrically connected to the heating component 8. The heating component 8 is used to heat the aerosol generating product to generate aerosol.

[0100] When the aerosol-generating substrate includes a liquid substrate stored in an aerosol substrate segment, the heating assembly 8 may include a liquid absorbing element and a heating element. The liquid absorbing element is configured to absorb the liquid substrate in the aerosol substrate segment and transfer the liquid substrate toward the heating element. The heating element is configured to release heat, thereby atomizing the liquid substrate to generate an aerosol.

[0101] Where the aerosol-generating substrate comprises a fixed substrate stored in an aerosol substrate segment, the heating assembly 8 may comprise an internal heating element, an external heating element and / or an air heating element.

[0102] The internal heating element is a heating element that is at least partially located inside the aerosol-generating substrate when the aerosol-generating device 100 is used in conjunction with an aerosol-generating article, thereby being able to internally heat the aerosol-generating substrate.

[0103] The external heating element is a heating element disposed outside the aerosol-generating substrate when the aerosol-generating device 100 is used in conjunction with an aerosol-generating article, so as to heat the aerosol-generating substrate externally. Figure 2The external heating element may comprise a tubular heating body 81 that can be disposed around at least a portion of the aerosol-generating article. Alternatively, for example, the external heating element may support the bottom or distal end of the aerosol-generating article, thereby heating the bottom or distal end of the aerosol-generating article.

[0104] The air heating element is a heating element that is arranged upstream of the aerosol generating product along the airflow direction and is used to heat the airflow passing through, thereby forming a high-temperature airflow, which then flows into the interior of the aerosol generating matrix, thereby utilizing the high-temperature airflow to heat the aerosol generating matrix.

[0105] The heating element may comprise a resistive material, an infrared coating and / or a susceptor.

[0106] The resistive material is capable of generating Joule heating when an electric current flows through it, and the resistive material can heat the aerosol-generating article primarily by heat conduction. Suitable resistive materials include, but are not limited to, semiconductors such as doped ceramics, conductive ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made from ceramic and metal materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include stainless steel, Constantan, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys, as well as superalloys based on nickel, iron, and cobalt, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys.

[0107] The infrared coating can radiate infrared radiation when thermally excited or when an electric current is passed through it. The infrared coating can heat the aerosol-forming substrate primarily through thermal radiation. The infrared coating can radiate infrared radiation with a wavelength of 0.75 μm to 1000 μm, preferably with a far-infrared radiation with a wavelength of 1.5 μm to 400 μm, and more preferably with a far-infrared radiation with a wavelength of 4 μm to 15 μm.

[0108] As used herein, the term "susceptor" refers to a material that can convert electromagnetic energy into heat. When placed within a varying electromagnetic field, eddy currents induced in the susceptor cause the susceptor to heat. In such embodiments, the susceptor is designed to engage a power supply assembly including a magnetic field generator. The magnetic field generator generates a varying magnetic field to heat the susceptor within the varying magnetic field. During use, the susceptor is placed within the varying magnetic field generated by the magnetic field generator. The magnetic field generator is electrically connected to the power supply assembly, which provides the magnetic field generator with current to generate the varying magnetic field. The magnetic field generator may include one or more induction coils that generate the varying magnetic field, and the one or more induction coils may surround the susceptor. In one embodiment, the aerosol generating device is capable of generating a varying magnetic field between 1 MHz and 30 MHz, such as between 2 MHz and 10 MHz, or between 5 MHz and 7 MHz. In one embodiment, the aerosol generating device is capable of generating a varying magnetic field having a field strength (H field) between 1 and 5 kA / m, such as between 2 kA / m and 3 kA / m, or approximately 2.5 kA / m.

[0109] The susceptor may comprise metal or carbon. In one embodiment, the susceptor may comprise a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In one embodiment, the susceptor comprises a nickel-iron alloy. In one embodiment, the susceptor comprises 400 series stainless steel, which includes 410, 420, or 430 grade stainless steel.

[0110] The power supply 91 may include any suitable battery, for example, a lithium battery. The aerosol generating device further includes a circuit board. The circuit board electrically connects the power supply 91 and the heating assembly 8. A controller or switch element on the circuit board can control the power supply 91 to output electrical power to the heating assembly 8.

[0111] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 further includes a second bracket 92. The second bracket 92 is provided with a mounting slot, into which at least a portion of the power supply 91 can be accommodated. The second bracket 92 can longitudinally support the first bracket 6 and / or the heating assembly 8. The second bracket 92 and the heating assembly 8 can be located within the housing 1.

[0112] In some embodiments, the aerosol generating device 100 further includes an interactive element 93 operable by a user, and the user controls the power supply 91 to provide electrical power to the heating assembly 8 by operating the interactive element 93. The interactive element 93 may be a button, a sliding switch, a touch screen, or a remote control.

[0113] In some embodiments, the aerosol-generating device 100 further comprises a detection sensor 94 for detecting the position of the movable cover 3, and when the movable cover 3 is not in the second position, the detection sensor 94 sends an instruction to the controller, so that the controller controls the power supply 91 to stop providing electric power to the heating assembly 8.

[0114] In other words, when the detection sensor 94 detects that the movable cover 4 is not in the second position, the power supply 91 is configured to be unable to provide electric power to the heating assembly 8, so as to prevent the user from triggering the interactive element 93 by mistake, so that the heating assembly 8 heats when there is no aerosol-generating article in the aerosol-generating device 100 when the first inlet 21 is closed.

[0115] In some embodiments, the movable cover 3 is provided with a magnetic member 35, which can include a magnet. The detection sensor 94 includes a Hall sensor 941 corresponding to the second position, and when the first inlet 21 is open, the movable cover 3 is in the second position, the magnetic member 35 interferes with the Hall sensor 941, so that at least one electrical parameter in the Hall sensor 941 changes, and the controller can determine whether the movable cover 3 is in the second position based on the change of the electrical parameter. If the movable cover 3 is not in the second position, the controller prohibits the power supply 91 from providing electric power to the heating assembly 8, and if the movable cover 3 is in the second position, the controller can control the power supply 91 to provide electric power to the heating assembly 8 under the further instruction of the interactive element 93.
