Description

Technical Field

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

[0002] An aerosol generating device is a device that can generate smoke from a tobacco product without combustion. In an existing aerosol generating device, it includes an end cap with a cigarette insertion port, a central heating element, and a cigarette holder. The tobacco product is inserted into the cigarette holder through the cigarette insertion port. A clamping portion is provided in the cigarette insertion port to clamp the tobacco product to prevent the tobacco product from being pulled out of the aerosol generating device when the user sucks on the mouthpiece of the tobacco product. The cigarette holder is loosely fitted with the tobacco product, and the cigarette holder can move up and down. When it moves upward, it can carry the tobacco product to move relative to the heating element, thereby preventing the tobacco product from breaking during the process of separating from the heating element.

[0003] During the use by the user, it is necessary to first make the cigarette holder carry the tobacco product to move upward, and then grasp the tobacco product to pull the tobacco product out of the cigarette holder. If the tobacco product is directly pulled when it is necessary to pull out the tobacco from the aerosol generating device, the tobacco product will break during the process of separating from the heating element.

[0004] However, when it is necessary to pull out the tobacco from the aerosol generating device, the inertial operation of the user is to directly grasp the tobacco product and pull it upward. Therefore, the existing method of using the aerosol generating device is contrary to the inertial operation of the user, resulting in a poor user experience and easy misoperation. Summary of the Utility Model

[0005] One of the purposes of the present application is to provide an aerosol generating device that conforms to the operating inertia of the user, so that the user has a better use experience.

[0006] An aerosol generating device provided by an embodiment of the present application includes:

[0007] A heating element;

[0008] A bracket; and

[0009] A moving assembly configured to be movable between a first position and a second position relative to the heating element. The moving assembly includes a clamping member and a receiving tube for receiving at least a part of the aerosol generating article. When the moving assembly is in the first position, at least a part of the heating element is located inside the receiving tube to insert into the aerosol generating article for heating;

[0010] The clamping member comprises a first operating portion and a first clamping portion for clamping the aerosol-generating article, wherein the first operating portion is configured to be slidably connected to the bracket and change its circumferential position during at least a portion of the movement of the moving assembly relative to the heating element;

[0011] The first clamping portion is arranged in linkage with the first operating portion, and the position and / or shape of the first clamping portion changes as the position of the first operating portion in the circumferential direction changes;

[0012] Wherein, when the movable component is located at the first position, there is a first distance between the first clamping portion and the central axis of the accommodating tube; when the movable component is located at the second position, there is a second distance between the first clamping portion and the central axis of the accommodating tube, and the first distance is smaller than the second distance.

[0013] As an example, a heating element;

[0014] stents; and

[0015] a moving assembly configured to be movable relative to the heating element between a first position and a second position, the moving assembly comprising a clamping member and a receiving tube for receiving at least a portion of the aerosol-generating article, wherein when the moving assembly is in the first position, at least a portion of the heating element is located within the receiving tube so as to be inserted into the aerosol-generating article for heating;

[0016] The clamping member comprises a first operating portion and a first clamping portion for clamping the aerosol-generating article, wherein the first operating portion is configured to be slidably connected to the bracket and change its circumferential position during at least a portion of the movement of the moving assembly relative to the heating element;

[0017] The first clamping portion is arranged in linkage with the first operating portion, and the position and / or shape of the first clamping portion changes as the position of the first operating portion in the circumferential direction changes;

[0018] Wherein, when the movable component is located at the first position, there is a first distance between the first clamping portion and the central axis of the accommodating tube; when the movable component is located at the second position, there is a second distance between the first clamping portion and the central axis of the accommodating tube, and the first distance is smaller than the second distance.

[0019] As an example, the travel of the moving assembly between the first position and the second position includes a first travel segment and a second travel segment, and along the direction in which the aerosol-generating article is removed from the containing tube, the first travel segment is located upstream of the second travel segment; wherein

[0020] When the moving component moves along the first section of the stroke, the distance between the first clamping portion and the central axis of the receiving tube remains substantially unchanged; when the moving component moves along the second section of the stroke, the distance between the first clamping portion and the central axis of the receiving tube gradually changes; and / or

[0021] When the moving component moves along the first section of the stroke, the position of the first operating portion in the circumferential direction of the receiving tube remains substantially unchanged, and when the moving component moves along the first section of the stroke, the position of the first operating portion in the circumferential direction of the receiving tube gradually changes.

[0022] As an example, the heating element extends longitudinally, the bracket includes a guiding groove having a first edge, the first edge includes a holding section extending substantially longitudinally and an expanding section extending obliquely or spirally, and at least a part of the first operating portion is located in the guiding groove;

[0023] When the moving component moves along the first section of the stroke, the first operating portion moves along the holding section;

[0024] When the moving component moves along the second section of the stroke, the first operating portion moves along the expanding section.

[0025] As an example, the guiding groove is a through groove or a blind groove.

[0026] As an example, a part of the clamping member is bent to form an elastic bent corner portion, and the bent corner portion connects the first operating portion through the first clamping portion to provide an elastic force through the first clamping portion, so that the first operating portion abuts against the first edge; and / or

[0027] At least a part of the first clamping portion extends in a curved manner and is connected to the first operating portion to provide an elastic force for the first operating portion to abut against the first edge.

[0028] As an example, the clamping member further includes a connecting portion connected to the receiving tube, the clamping member includes an elastic bent corner portion, and the first clamping portion and the connecting portion respectively extend from opposite ends of the bent corner portion;

[0029] When the moving component moves along the second section of the stroke, the first clamping portion rotates relative to the connecting portion, thereby changing the angle and elastic tension of the bent corner portion;

[0030] Wherein, the angle of the bent corner portion when the moving component moves along the holding section stroke is smaller than the angle when the moving component moves along the expanding section stroke.

[0031] As an example, a strip-shaped groove is formed in the wall of the receiving tube, one end of the first operating part is movably connected to the bracket, and the other end passes through the strip-shaped groove and is connected to the first clamping part;

[0032] The strip-shaped groove extends along the circumferential direction of the receiving tube, and during at least part of the stroke of the moving assembly moving between the first position and the second position, the first operating part is displaced along the strip-shaped groove.

[0033] As an example, the proximal end of the receiving tube has an opening allowing the aerosol-generating article to be inserted, the receiving tube has a first receiving cavity and a second receiving cavity for receiving the aerosol-generating article, the inner diameter of the first receiving cavity is larger than that of the second receiving cavity, and the first receiving cavity is located between the opening and the second receiving cavity;

[0034] The first clamping part is located in the first receiving cavity, and when the moving assembly is in the second position, the second spacing is greater than or equal to the receiving radius of the second receiving cavity.

[0035] As an example, the inner wall of the receiving tube has a support platform, and the support platform is located at the boundary between the first receiving cavity and the second receiving cavity;

[0036] When the moving assembly is in the first position, at least part of the first clamping part is spaced from the support platform;

[0037] When the moving assembly is in the second position, the first clamping part is supported by the support platform.

[0038] As an example, when the moving assembly is in the first position, the first spacing is less than the receiving radius of the second receiving cavity.

[0039] As an example, the clamping member further includes a second operating part and a second clamping part for clamping the aerosol-generating article, the second operating part is configured to be slidably connected to the bracket during at least part of the stroke of the moving assembly moving relative to the heating element, and the position in the circumferential direction changes;

[0040] The second clamping part is linked with the second operating part, and the position and / or shape of the second clamping part change with the change of the position of the second operating part in the circumferential direction;

[0041] The spacing between the second clamping part and the central axis of the receiving tube when the moving assembly is in the first position is less than the spacing between the second clamping part and the central axis of the receiving tube when the moving assembly is in the second position.

[0042] As an example, when the moving component is in the first position, there is a first distance between the second clamping portion and the central axis of the receiving cavity, and when the moving component is in the second position, there is a second distance between the second clamping portion and the central axis of the receiving cavity.

[0043] As an example, the first clamping portion and the second clamping portion are located on opposite sides inside the receiving tube, and the first clamping portion and the second clamping portion are configured to have opposite moving directions or deformation directions.

[0044] As an example, the clamping member further includes a connecting portion connected to the receiving tube, and the first clamping portion and the second clamping portion are symmetrically arranged and are respectively connected to opposite ends of the connecting portion.

[0045] As an example, the aerosol generating device further includes a stop portion, and when the moving component is in the second position, the stop portion abuts against the moving component.

[0046] As an example, the bracket has a receiving cavity, and at least a part of the receiving tube is movably arranged in the receiving cavity;

[0047] The aerosol generating device further includes a fixing seat, the fixing seat is connected to the bracket and defines a part of the boundary of the receiving cavity, and one end of the heating element is fixed on the fixing seat;

[0048] When the moving component is in the first position, the fixing seat supports the receiving tube, and / or the bracket supports the first operating portion.

[0049] An aerosol generating device provided by an embodiment of the present application includes:

[0050] A heating element; and

[0051] A moving component configured to be movable relative to the heating element between a first position and a second position, the moving component includes a clamping member and a receiving tube for at least partially accommodating an aerosol generating article. When the moving component is in the first position, at least a part of the heating element is located inside the receiving tube to insert into the aerosol generating article for heating, and the moving stroke of the moving component between the first position and the second position includes a first stroke and a second stroke. Along the direction in which the aerosol generating article is removed from the receiving tube, the first stroke is located upstream of the second stroke;

[0052] The clamping member includes a first clamping portion for clamping the aerosol generating product. When the moving component moves along the first stroke, the distance between the first clamping portion and the central axis of the containing tube basically remains unchanged at a first distance; when the moving component moves along the second stroke, the distance between the first clamping portion and the central axis of the containing tube is greater than the first distance.

[0053] As an example, along the direction of removing the aerosol-generating article from the containing tube, the first position is the starting point of the first stroke; and / or

[0054] The second position is an end point of the second stroke along the direction in which the aerosol-generating article is removed from the containing tube.

[0055] As an example, along the direction in which the aerosol-generating article is removed from the containing tube, when the moving assembly moves along the second stroke, the distance between the first clamping portion and the central axis of the containing tube gradually increases.

[0056] The above aerosol generating device includes a bracket, a moving component and a heating element for heating the aerosol generating product. The moving component can move between a first position and a second position relative to the heating element, and the moving component includes a clamping member and a accommodating tube for accommodating at least part of the aerosol generating product. The clamping member includes a first operating part and a first clamping part for clamping the aerosol generating product. During at least part of the stroke of the moving component moving relative to the heating element, the first operating part is slidably connected to the bracket and its circumferential position changes. The first clamping part is linked to the first operating part, and the position and / or shape of the first clamping part changes with the change of the circumferential position of the first operating part; when the moving component is in the first position, there is a first distance between the first clamping part and the central axis of the accommodating tube, and when the moving component is in the second position, there is a second distance between the first clamping part and the central axis of the accommodating tube, and the first distance is smaller than the second distance.

[0057] Therefore, when the movable assembly is in the first position where the heating element heats the aerosol-generating product, the first clamping portion exerts a greater clamping force on the aerosol-generating product. Thus, when the user directly operates the aerosol-generating product in the direction of removing the aerosol-generating product from the housing tube, the movable assembly can move along with the aerosol-generating product, thereby loosening the adhesion between the aerosol-generating product and the heating element, thereby effectively preventing the aerosol-generating product from breaking. When the movable assembly is in the second position, the first clamping portion exerts a smaller or no clamping force on the aerosol-generating product, thereby facilitating the removal of the aerosol-generating product from the housing tube. Therefore, the user can use the aerosol-generating device according to their operating habits, providing a better user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0084] The terms "first", "second", and "third" in the present application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity or order of the indicated technical features. All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship or movement situation between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0085] Referring to "embodiments" herein means that a specific feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0086] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element, or there may be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0087] Please refer to Figure 1 and Figure 2 , some embodiments of the present application provide an aerosol generating device, which is a device capable of generating an aerosol from an aerosol generating article 1 without combustion.

[0088] As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming substrate 11 that is capable of releasing aerosol-formable volatile compounds when reaching a certain temperature. Compared with the aerosol generated by burning or pyrolytic degradation of the aerosol-forming substrate, the aerosol formed by heating the aerosol-forming substrate may contain fewer known harmful components. In some embodiments, the aerosol-generating article 1 is removably coupled to an aerosol-generating device. The aerosol-generating article 1 can be disposable or reusable.

[0089] The aerosol-forming substrate 11 may comprise a solid aerosol-forming substrate. The solid aerosol-forming substrate may comprise a tobacco-containing material that contains volatile tobacco flavor compounds released from the substrate upon heating. The solid aerosol-forming substrate may comprise a non-tobacco material. The solid aerosol-forming substrate may comprise a tobacco-containing material and a tobacco-free material. When the aerosol-forming substrate is a solid aerosol-forming substrate, the aerosol-generating article may be a smoking block, a cigarette, a smoking rod, or a cigar, etc.

[0090] In some embodiments, the aerosol-generating article 1 further comprises a mouthpiece 12. When the aerosol-generating article 1 is coupled to the aerosol-generating device, the mouthpiece 12 is exposed outside the aerosol-generating device for the user's mouth to hold. The user inhales the aerosol generated in the aerosol-forming substrate 11 by sucking on the mouthpiece 12. The user can also operate the part of the aerosol-generating article 1 that is exposed outside the aerosol-generating device, such as pulling up the mouthpiece 12 in the pulling-out direction and then removing the aerosol-generating article 1 from the aerosol-generating device.

[0091] In some embodiments of the present application, please refer to Figure 1 and Figure 2 , the aerosol-generating device comprises a heating element 2 and a holder 3. One end of the heating element 2 is fixed on the holder 3. When the aerosol-generating article 1 is coupled to the aerosol-generating device, at least a part of the heating element 2 is inserted into the aerosol-generating article 1, so that the heating element 2 can heat the aerosol-generating article 1 inside the aerosol-generating article 1, causing the aerosol-generating article 1 to generate aerosol. Based on this, the heating element 2 can generally be needle-shaped, sheet-shaped, or rod-shaped with a conical top extending along the longitudinal direction Y. Of course, it can also be other shapes.

[0092] In some examples, the heating element 2 includes a resistive material that can generate Joule heat when obtaining a voltage or current. 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 of ceramic materials 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 nickel-based, iron-based, and cobalt-based superalloys, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys.

[0093] The resistive material can form a resistive coating or a resistive heating track coated on a substrate, or the resistive material can form an electrothermal wire or an electrothermal mesh.

[0094] In some examples, the heating element 2 includes a substrate and an infrared material coated on the substrate. The infrared material can radiate infrared rays when being excited or when obtaining a voltage or current, for example, emitting infrared rays of 0.75 μm to 1000 μm, preferably emitting far-infrared rays of 1.5 μm to 400 μm, or preferably emitting far-infrared rays of 8 μm to 15 μm.

[0095] In some examples, the heating element 2 includes a susceptor. As used herein, the term "susceptor" refers to a material that can convert electromagnetic energy into heat. When located in a changing electromagnetic field, eddy currents induced in the susceptor cause heating of the susceptor. Among them, the susceptor can include metal or carbon. In one embodiment, the susceptor may include a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In one embodiment, the susceptor includes a nickel-iron alloy. In one embodiment, the susceptor includes a 400 series stainless steel, and the 400 series stainless steel includes grade 410 or grade 420 or grade 430 stainless steel.

[0096] When the heating element 2 includes a susceptor, the aerosol generating device further includes a magnetic field generator. The magnetic field generator is electrically connected to a power supply assembly, and the power supply assembly provides a current for the magnetic field generator to generate a changing magnetic field. When the susceptor is located in the changing magnetic field generated by the magnetic field generator, heat can be generated. The magnetic field generator may include one or more induction coils that generate a changing magnetic field, and the one or more induction coils can surround the susceptor.

[0097] It should be noted that the aerosol generating device may include one or more heating elements. At least a part of one heating element is used to heat the aerosol generating article inside the aerosol generating article, while other heating elements may heat the aerosol generating article outside the aerosol generating article, or heat the aerosol generating article by heating air and then using the hot air.

[0098] In some embodiments of the present application, please refer to Figure 1 and Figure 2 , the aerosol generating device includes a moving component 4, and the moving component 4 is arranged to be movable between a first position and a second position relative to the heating element 2.

[0099] Reference may be made to Figures 1 - 3 , the moving component 4 includes a receiving tube 41, and the inside of the receiving tube 41 has a receiving cavity 411 extending longitudinally in the Y direction. When the aerosol generating article 1 is coupled to the aerosol generating device, at least a part of the aerosol generating article 1 is located in the receiving cavity 411. The proximal end of the receiving tube 41 has an opening, and the aerosol generating article 1 is inserted into the receiving cavity 411 through the opening. The distal end of the receiving tube 4 or the inside of the receiving tube 41 has a base 412. When the aerosol generating article 1 is coupled to the aerosol generating device, the base 412 supports the bottom of the aerosol generating article 1, wherein the bottom of the aerosol generating article 1 is disposed opposite to the mouthpiece 12 of the aerosol generating article 1.

[0100] The receiving tube 4, as a component of the moving component 4, can thus move relative to the heating element 2. For example, the receiving tube 41 can move between a first position and a second position relative to the heating element 2 along a longitudinal track, or for example, the receiving tube 41 can move between a first position and a second position relative to the heating element 2 along a spiral track.

[0101] By moving the receiving tube 41 relative to the heating element 2, the depth at which the heating element 2 is inserted into the receiving cavity 411 is changed, and thus the depth at which the heating element 2 is inserted into the aerosol generating article 1 is changed. And in at least a part of the stroke where the depth at which the heating element 2 is inserted into the aerosol generating article 1 is reduced, the base 412 of the receiving tube 41 can keep supporting the bottom of the aerosol generating article 1, so that on the one hand, the aerosol generating article 1 can be prevented from breaking, and on the other hand, the adhesion between the heating element 2 and the aerosol generating article 1 can be loosened or released, facilitating the removal of the aerosol generating article 1 from the aerosol generating device and the removal of the receiving tube 41.

[0102] When the moving component 4 is in the first position, at least a part of the heating element 2 passes through the through hole 4121 on the base 412 of the receiving tube 41 and is located in the receiving cavity 411. At this time, the heating element 2 can generate heat to heat the aerosol generating article 1 in the receiving cavity 411. When the moving component 4 is in the second position, a part of the heating element 2 may still be located in the receiving cavity 411. Of course, the heating element 2 may also be located outside the receiving cavity 411; the distance between the receiving tube 41 and the fixed seat 3 when the moving component 4 is in the second position is greater than the distance between the receiving tube 41 and the fixed seat 3 when the moving component 4 is in the first position.

[0103] In some embodiments of the present application, reference may be made to Figures 4 - 6 , the moving component 4 further includes a clamping member 42 having a first clamping portion 421, so that the clamping member 42 can move relative to the heating element 2. For example, when the moving component 4 moves between the first position and the second position, the first clamping portion 421 has a movement component along the longitudinal direction Y; for example, when the moving component 4 moves between the first position and the low temperature position, the first clamping portion 421 can have a displacement relative to the heating element 2 in the longitudinal direction Y.

[0104] Reference may be made to Figure 11 and Figure 15 , at least a part of the first clamping portion 421 is located in the receiving cavity 411 for clamping the aerosol generating article 1. When the moving component 4 is in the first position, there is a first distance L1 between the first clamping portion 421 and the central axis of the receiving tube 41 / receiving cavity 411. When the moving component 4 is in the second position, there is a second distance L2 between the first clamping portion 421 and the central axis of the receiving tube 41 / receiving cavity 411, and the first distance L1 is less than the second distance L2. Therefore, the clamping force of the first clamping portion 421 on the aerosol generating article 1 when the moving component 4 is in the first position is greater than the clamping force of the first clamping portion 421 on the aerosol generating article 1 when the moving component 4 is in the second position. In other words, the tightness between the moving component 4 and the aerosol generating article 1 when the moving component 4 is in the first position is greater than the tightness between the moving component 4 and the aerosol generating article 1 when the moving component 4 is in the second position.

[0105] When the user operates the part of the aerosol-generating article 1 that is exposed outside the aerosol-generating device, such as the mouthpiece, when the moving component 4 is in the first position, it helps the moving component 4 to overcome its own gravity and then move relative to the heating element 2 together with the aerosol-generating article 1, so that the receiving tube 41 maintains the support and protection of the aerosol-generating article 1, thereby preventing the aerosol-generating article 1 from breaking and loosening or releasing the adhesion between the heating element 2 and the aerosol-generating article 1. When the moving component 4 is in the second position, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 is reduced, and the adhesion between the heating element 2 and the aerosol-generating article 1 has been loosened or released, so that the user can easily move the aerosol-generating article 1 relative to the moving component 4, and then gradually remove it from the receiving tube 41.

[0106] Preferably, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 when the moving component 4 is in the first position is greater than the gravity of the moving component 4 itself; and the clamping force of the first clamping portion 421 on the aerosol-generating article 1 when the moving component 4 is in the second position can be greater than or equal to the gravity of the moving component 4 itself, can also be less than the gravity of the moving component 4 itself, or can even have no clamping force on the aerosol-generating article 1.

[0107] In some embodiments of the present application, the moving stroke of the moving component 4 between the first position and the second position includes a first stroke and a second stroke. Along the direction in which the aerosol-generating article 1 is removed from the receiving tube 41, the first stroke is upstream of the second stroke, that is, when the removal component 4 moves from the first position to the second position, the moving component 4 first moves along the first stroke and then moves along the second stroke.

[0108] Among them, when the moving component 4 moves along the first stroke, the distance between the first clamping portion 421 and the central axis of the receiving tube 41 basically remains the first distance L1 unchanged. Thus, when the moving component 4 moves along the first stroke, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 basically remains unchanged, so as to ensure that when the user operates the part of the aerosol-generating article 1 that is exposed outside the aerosol-generating device, such as the mouthpiece, during the movement of the moving component 4 along the first stroke, the receiving tube 41 can remain relatively stationary with the aerosol-generating article 1, and the receiving tube 41 can move relative to the heating element 2 synchronously with the aerosol-generating article 1, which helps to ensure that during the process that the displacement of the aerosol-generating article 1 in the longitudinal direction Y reaches a certain length, the receiving tube 41 can stably support and protect the aerosol-generating article 1, thereby relatively fully reducing the resistance of the heating element 2 to the aerosol-generating article 1 and preventing the aerosol-generating article 1 from breaking during the subsequent removal process.

[0109] When the moving component 4 moves along the first section of the stroke, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 remains greater than the gravity of the moving component 4.

[0110] When the moving component 4 moves along the second section of the stroke, the distance between the first clamping portion 421 and the central axis of the receiving tube 41 is greater than the first distance L1. Thus, during the process of the moving component 4 moving along the second section of the stroke, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 is relatively small.

[0111] As an example, during at least a part of the process when the moving component 4 moves along the second section of the stroke, due to the relatively small clamping force of the first clamping portion 421 on the aerosol-generating article 1, the moving speed of the moving component 4 is less than the moving speed of the aerosol-generating article 1. Thus, during the process of the moving component 4 moving along the second section of the stroke, the aerosol-generating article 1 begins to move relative to the moving component 4 and thus begins to separate from the moving component 4. As an example, the moving speed of the moving component 4 is equal to the moving speed of the aerosol-generating article 1, so that during the process of the moving component 4 moving along the second section of the stroke, the aerosol-generating article 1 and the moving component 4 still remain synchronized.

[0112] As an example, during at least a part of the process when the moving component 4 moves along the second section of the stroke, the distance between the first clamping portion 421 and the central axis of the receiving tube 41 gradually changes, and the clamping force of the first clamping portion 421 on the aerosol-generating article 1 changes accordingly.

[0113] Furthermore, along the direction in which the aerosol-generating article 1 is removed from the receiving tube 41, when the moving component 4 moves along the second section of the stroke, the distance between the first clamping portion 421 and the central axis of the receiving tube 41 gradually increases. Thus, along the direction in which the aerosol-generating article 1 is removed from the receiving tube 41, when the moving component 4 moves along the second section of the stroke, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 gradually decreases.

[0114] Even further, along the direction in which the aerosol-generating article 1 is removed from the receiving tube 41, when the moving component 4 moves along the second section of the stroke, the minimum distance between the first clamping portion 421 and the central axis of the receiving tube 41 is greater than or equal to the first distance L1. Thus, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 when the moving component 4 moves along the first section of the stroke is greater than or equal to the maximum clamping force of the first clamping portion 41 on the aerosol-generating article 1 when the moving component 4 moves along the second section of the stroke.

[0115] As an example, along the direction in which the aerosol-generating article 1 is removed from the receiving tube 41, the first position is the starting point of the first section of the stroke. As an example, along the direction in which the aerosol-generating article 1 is removed from the receiving tube 41, the second position is the end point of the second section of the stroke.

[0116] In an embodiment of the present application, the track length of the first stroke is less than the track length of the second stroke. In an embodiment of the present application, the component of the track length of the first stroke in the longitudinal direction Y is less than the component of the track length of the second stroke in the longitudinal direction Y. In an embodiment of the present application, when the moving component 4 moves along the first stroke and / or the second stroke, the receiving tube 41 moves along the longitudinal direction Y.

[0117] It should be noted that, in one example, the first stroke and the second stroke may be continuous. Alternatively, in another example, there may also be a third stroke between the first stroke and the second stroke. In one example, there is also a fourth stroke between the first position and the first stroke. In one example, there is also a fifth stroke between the second position and the second stroke.

[0118] It should be noted that the first stroke is optional rather than mandatory.

[0119] In an embodiment of the present application, the first spacing L1 can be made less than the second spacing L2 by making the shape of the first clamping portion 421 when the moving component 4 is in the first position different from the shape when the moving component 4 is in the second position. And / or, the first spacing L1 can be made less than the second spacing L2 by making the position of the first clamping portion 421 when the moving component 4 is in the first position different from the position when the moving component 4 is in the second position.

[0120] Based on this, in some embodiments, the clamping member 42 further includes a first operating portion 422. During at least part of the stroke when the moving component 4 moves relative to the heating element 2, the position of the first operating portion 422 changes in the circumferential direction Z. The first operating portion 422 is linked with the first clamping portion 421 so as to change the shape and / or position of the first clamping portion 421 by changing the position of the first operating portion 422 in the circumferential direction Z, thereby changing the spacing between the first clamping portion 421 and the central axis of the receiving tube 41 or the receiving cavity 411.

[0121] Among them, the first operating portion 422 can be hidden in the aerosol generating device so that the user cannot directly operate the first operating portion 422. Specifically, reference can be made to Figures 7 - 9 and Figures 12 - 14 , the aerosol generating device further includes a bracket 5. During at least part of the stroke when the moving component 5 moves relative to the heating element 2, the first operating portion 422 is slidably connected to the bracket 5. Thus, the bracket 5 can guide and limit the movement of the first operating portion 422, and the shape and / or position of the first clamping portion 421 can be changed through the interference fit between the bracket 5 and the first operating portion 422.

[0122] As an example, reference can be made toFigure 7 , Figure 8 and Figure 13 , the bracket 5 includes a guiding groove 51 having a first edge 511. The first edge 511 includes a holding section 5111 extending substantially longitudinally and an expanding section 5112 extending obliquely or spirally. At least a part of the first operating portion 422 is located in the guiding groove 51.

[0123] When the moving assembly 4 moves along the first stroke, the first operating portion 422 moves along the holding section 5111. Thus, when the moving assembly 4 moves along the first stroke, the position of the first operating portion 422 in the circumferential direction Z remains substantially unchanged. Therefore, the distance between the first clamping portion 421 and the central axis of the receiving tube 41 can remain substantially unchanged, and the clamping force of the first clamping portion 421 on the aerosol-generating article 1 remains substantially unchanged.

[0124] When the moving assembly 4 moves along the second stroke, the first operating portion 422 moves along the expanding section 5112. Thus, when the moving assembly 4 moves along the second stroke, the position of the first operating portion 422 in the circumferential direction Z gradually changes. Therefore, the distance between the first clamping portion 421 and the central axis of the receiving tube 41 gradually changes, and the clamping force of the first clamping portion 421 on the aerosol-generating article 1 gradually changes.

[0125] Along the direction in which the aerosol-generating article 1 is removed from the receiving tube 41, when the moving assembly 4 moves along the second stroke, the displacement amount of the first operating portion 422 in the circumferential direction Z gradually increases. Therefore, the distance between the first clamping portion 421 and the central axis of the receiving tube 41 gradually increases, and the clamping force of the first clamping portion 421 on the aerosol-generating article 1 gradually decreases.

[0126] In Figure 8 the illustrated embodiment, the extending length of the holding section 5111 is less than that of the expanding section 5112, but this is not limiting.

[0127] In Figure 8 the illustrated embodiment, the distal end of the guiding groove 51 has a stop wall 5113. When the moving assembly 4 is in the first position, the fixing seat 3 supports the receiving tube 41, and / or the stop wall 5113 supports the first operating portion 422 to prevent the moving assembly 4 from continuing to move along the direction from the second position to the first position. In other words, when the moving assembly 4 is in the first position, the fixing seat 3 supports the receiving tube 41, and / or the bracket 5 supports the first operating portion 422.

[0128] In Figure 7In the illustrated embodiment, the holder 5 includes a receiving tube 52 having a receiving cavity 521 therein. At least a part of the receiving tube 41 is movably disposed in the receiving cavity 521. A guiding groove 51 is formed in the tube wall of the receiving tube 52, which may be a through groove that penetrates the tube wall of the receiving tube 52 and communicates the inside and outside of the receiving tube 52. Of course, the guiding groove 51 may be a blind groove, which may be formed by recessing from the inner surface of the tube wall of the receiving tube 52. The provision of the blind groove can keep the tube wall of the receiving tube 52 in good integrity and prevent the aerosol generated by the aerosol generating article 1 from leaking through the tube wall of the receiving tube 52.

[0129] Preferably, the fixing seat 3 is connected to the holder 5, and the fixing seat 3 defines at least part of the boundary of the bottom of the receiving cavity 521. More preferably, the connection between the fixing seat 3 and the receiving tube 52 is a sealed connection to prevent the aerosol and the condensate formed by the aerosol condensation from leaking from the connection between the fixing seat 3 and the receiving tube 52.

[0130] In Figure 12 In the illustrated embodiment, the aerosol generating device further includes a stop portion 61. When the moving assembly 4 is in the second position, the stop portion 61 abuts against the moving assembly 4 to prevent the moving assembly 4 from being removed from the aerosol generating device or from the receiving tube 52, so that the moving assembly 4 is hidden inside the aerosol generating device when in the first position and the second position. It should be noted that it is optional rather than necessary that the moving assembly 4 is non-removably disposed inside the aerosol generating device or inside the receiving tube 52, and it is optional rather than necessary that the moving assembly 4 is hidden inside the aerosol generating device when in the first position and the second position.

[0131] Furthermore, the aerosol generating device further includes an end cap 6. An insertion hole 62 for inserting the aerosol generating article 1 into the receiving tube 41 is formed in the end cap 6. The stop portion 61 is provided on the end cap 6 or integrally formed with the end cap 6.

[0132] Preferably, the end cap 6 is hermetically connected to the holder 5 to prevent the aerosol or the condensate formed by the aerosol from leaking from the connection between the holder 5 and the end cap 6.

[0133] As an example, the aerosol generating device has an air flow channel for guiding the outside air into the distal end of the receiving tube 41, and at least part of the air flow channel may be provided between the receiving tube 41 and the receiving tube 52. Further, the insertion hole 62 communicates the outside with the air flow channel. The outside air enters the air flow channel through the insertion hole 62, then flows through the air flow channel to the distal end of the receiving cavity 411, and then enters the aerosol generating article 1 from the bottom of the aerosol generating article 1.

[0134] As an example, the inner wall of the receiving tube 41 has a groove 413. When the aerosol-generating article 1 is coupled to the receiving tube 41, the air flow is unobstructed in the groove 413, enabling the groove 413 to guide the outside air to the distal end of the receiving tube 41, and then the air enters the aerosol-generating article 1 from the bottom of the aerosol-generating article 1.

[0135] As an example, reference may be made to Figure 7 and Figure 16 such that the receiving tube 41 is slidably connected to the receiving tube 52. Specifically, a slide rail 414 is provided on one of the receiving tube 41 and the receiving tube 52, and a sliding portion 53 is provided on the other. The sliding portion 53 is slidably connected to the slide rail 414. The slide rail 414 is configured to guide the moving direction when the receiving tube 41 and the receiving tube 52 move relative to each other, enabling the receiving tube 41 to move relative to the heating element 2 in the receiving tube 52 along a preset track. Preferably, the slide rail 414 extends along the longitudinal direction Y, such that the receiving tube 41 moves relative to the bracket 5 and the heating element 2 along the longitudinal direction Y. Thus, when the user operates the part of the aerosol-generating article 1 that is exposed outside the aerosol-generating device, the aerosol-generating article 1 can be directly moved relative to the aerosol-generating device along the longitudinal direction Y.

[0136] In some embodiments of the present application, the first operation portion 422 can automatically adapt to the change of the first edge 511. Based on this, the first operation portion 422 elastically abuts against the first edge 511.

[0137] As an example, reference may be made to Figure 4 and Figure 5 such that a locally bent portion of the clamping member 42 forms an elastic bent angle portion 426. The bent angle portion 426 is connected to the first operation portion 422 through the first clamping portion 412 to provide an elastic force through the first clamping portion 412, so that the first operation portion 422 remains in abutment with the first edge 511.

[0138] Further, the clamping member 42 further includes a connecting portion 423. The connecting portion 423 remains connected to the receiving tube 41. The first clamping portion 421 and the connecting portion 423 extend from opposite ends of the bending angle portion 426 respectively. When the moving assembly 4 moves along the second stroke, the expanding section 5112 extends obliquely or spirally. Therefore, the position of the first operating portion 421 changes in the longitudinal direction Y, and the first operating portion 422 remains in contact with the expanding section 5112 under the action of elastic force. Thus, the first operating portion 422 keeps moving along the expanding section 5112, so that the position of the first operating portion 422 also changes in the circumferential direction Z. As a result, the first clamping portion 421 rotates relative to the connecting portion 423, thereby not only changing the position of the first clamping portion 421, but also changing the angle θ and elastic tension of the bending angle portion 426. The changed elastic tension continues to act on the first operating portion 422 through the first clamping portion 421, so that the first operating portion 422 continues to maintain elastic contact with the expanding section 5112. Thus, the first operating portion 422 can automatically adapt to the oblique extension or spiral extension of the expanding section 5112.

[0139] As an example, reference may be made to Figure 4 and Figure 5 , at least a part of the first clamping portion 421 extends in a curved manner and is connected to the first operating portion 422 to provide an elastic force for the first operating portion 422 to remain in contact with the first edge 511. When the moving assembly 4 moves along the second stroke, the elastic tension of the first clamping portion 421 changes, so that the curvature of the first clamping portion 421 changes and the shape changes, making the first operating portion 421 remain in elastic contact with the expanding section 5112 and being able to automatically adapt to the oblique extension or spiral extension of the expanding section 5112.

[0140] Preferably, at least a part of the first clamping portion 421 of the clamping member 42 extends in a curved manner. At the same time, opposite ends of the first clamping portion 421 are respectively connected to the first operating portion 422 and the connecting portion 423. The bracket 5 provides a force through the first operating portion 422, and the receiving tube 41 provides a force through the connecting portion 423, so that the first clamping portion 421 clamps the aerosol generating article 1. Preferably, at least a part of the first clamping portion 421 of the clamping member 42 extends in a curved manner. At the same time, the clamping member further includes a bending angle portion 426, and the bending angle portion 426 is arranged between the first clamping portion 421 and the connecting portion 423.

[0141] In some embodiments of the present application, reference may be made to Figure 10 and Figure 16, a strip-shaped groove 415 is formed in the wall of the receiving tube 41. One end of the first operating portion 421 is movably connected to the bracket 5, and the other end passes through the strip-shaped groove 415 and is connected to the first clamping portion 421. The strip-shaped groove 415 extends along the circumferential direction of the receiving cavity 411. During at least part of the stroke of the moving assembly 4 moving between the first position and the second position, the first operating portion 421 is displaced along the strip-shaped groove 415. Specifically, when the moving assembly 4 moves along the first stroke, the first operating portion 421 moves along the holding section 5111, and the position of the first operating portion 422 in the strip-shaped groove 415 remains substantially unchanged; when the moving assembly 4 moves along the second stroke, the first operating portion 422 moves along the expanding section 5112, and the first operating portion 422 is displaced circumferentially along the Z direction in the strip-shaped groove 415.

[0142] In some embodiments of the present application, reference may be made to Figure 12 , the receiving tube 41 has a first receiving cavity 4111 and a second receiving cavity 4112 for receiving the aerosol-generating article 1. The first receiving cavity 4111 is located between the opening at the proximal end of the receiving tube 41 and the second receiving cavity 4112. The first clamping portion 421 is located in the first receiving cavity 4111, and when the moving assembly 4 is in the second position, the second distance L2 is greater than or equal to the receiving radius (minimum radius) of the second receiving cavity 4222. Therefore, when the moving assembly 4 is in the second position, the clamping force of the first clamping portion 421 on the aerosol-generating article 1 is less than the clamping force of the receiving tube 41 on the aerosol-generating article 1; or, when the moving assembly 4 is in the second position, the first clamping portion 421 is spaced apart from or slightly contacts the aerosol-generating article 1. In other words, when the moving assembly 4 is in the second position, the second distance L2 is greater than or equal to the radius of the aerosol-generating article 1, so that the first clamping portion 421 loses the clamping effect on the aerosol-generating article 1 or has a slightly clamping effect.

[0143] Furthermore, reference may be made to Figures 9 - 12 , the inner wall of the receiving tube 41 has a support platform 416, and the support platform 416 is located at the boundary between the first receiving cavity 4111 and the second receiving cavity 4112. When the moving assembly 4 is in the first position, reference may be made to Figure 11 , at least a part of the first clamping portion 421 is spaced apart from the support platform 416, so that the first distance L1 is less than the receiving radius of the second receiving cavity 4112 or less than the radius of the aerosol-generating article 1. When the moving assembly 4 is in the second position, reference may be made to Figure 14 , the first clamping portion 421 is supported by the support platform 416.

[0144] In some embodiments of the present application, reference may be made to Figure 5 and Figure 6, the clamping member 42 further includes a second operating portion 425 and a second clamping portion 424 for clamping the aerosol generating article 1. The second operating portion 425 is configured to be slidably connected to the bracket 5 during at least a part of the stroke of the moving assembly 4 moving relative to the heating element 2, and its position in the circumferential direction Z changes; the second clamping portion 424 is linked with the second operating portion 425, and the position and / or shape of the second clamping portion 424 changes as the position of the second operating portion 425 in the circumferential direction Z changes; when the moving assembly 4 is in the first position, the distance between the second clamping portion 424 and the central axis of the receiving cavity 411 is smaller than the distance between the second clamping portion 424 and the central axis of the receiving cavity 411 when the moving assembly 4 is in the second position.

[0145] Further, when the moving assembly 4 is in the first position, there is a first distance L1 between the second clamping portion 424 and the central axis of the receiving cavity 411, which is equal to the distance between the first clamping portion 421 and the central axis of the receiving cavity 411; when the moving assembly 4 is in the second position, there is a second distance L2 between the second clamping portion 424 and the central axis of the receiving cavity 411, which is equal to the distance between the first clamping portion 421 and the central axis of the receiving cavity 411.

[0146] In one example, reference may be made to Figures 9 - 11 , the first clamping portion 421 and the second clamping portion 424 are located on opposite sides inside the receiving tube 41. During at least a part of the stroke of the moving assembly 4 moving between the first position and the second position, the moving directions or deformation directions of the first clamping portion 421 and the second clamping portion 424 are opposite, wherein the first clamping portion 421 and the second clamping portion 424 can move or deform simultaneously, or can move or deform non-simultaneously. In other examples, the first clamping portion 421 and the second clamping portion 424 can be located on the same side of the receiving cavity 411. During at least a part of the stroke of the moving assembly 4 moving between the first position and the second position, the first clamping portion 421 and the second clamping portion 424 can have the same moving direction or deformation direction.

[0147] In one example, the clamping member 42 further includes a connecting portion 423 that remains connected to the receiving tube 41. The first clamping portion 421 and the second clamping portion 424 are symmetrically arranged and are respectively connected to opposite ends of the connecting portion 423. Further, reference may be made to Figures 4 - 6 , the clamping member 42 is an integrally formed plastic part, or an integrally formed metal wire, metal sheet or metal strip. Reference may be made to Figure 6 , the longitudinal section of the clamping member 42 can be generally in the shape of "(" or "<". In the embodiments shown in Figure 5 and Figure 6 , the clamping member 42 is configured in an axisymmetric shape.

[0148] In some embodiments of the present application, reference may be made toFigures 4 - 6 The clamping member 42 includes a second clamping portion 424 for clamping the aerosol generating article 1. When the moving assembly 4 moves along the first stroke, the distance between the second clamping portion 424 and the central axis of the receiving tube 41 remains substantially the first distance unchanged; when the moving assembly 4 moves along the second stroke, the distance between the second clamping portion 424 and the central axis of the receiving tube 41 is greater than the first distance.

[0149] In Figure 10 , Figure 16 and Figure 17 In the embodiments shown, a first retaining member 417 and a second retaining member 418 are provided on the receiving tube 41. The first retaining member 417 and the second retaining member 418 are spaced apart. A retaining groove 4181 is provided on the side of the second retaining member 418 facing away from the receiving cavity 411. At least a part of the connecting portion 423 of the clamping member 42 is embedded in the retaining groove 4181 for retention. A part of the clamping member 42 passes through the gap between the first retaining member 417 and the second retaining member 418, and the first clamping portion 421 of the clamping member 42 is located on the side of the first retaining member facing the receiving cavity 411.

[0150] Furthermore, both the first retaining member 417 and the second retaining member 418 define part of the boundary of the first receiving cavity 4111, and the support platform 416 defines the distal boundary of the gap between the first retaining member 417 and the second retaining member 418. The proximal end of the gap between the first retaining member 417 and the second retaining member 418 is open, so that when connecting the clamping member 42 to the receiving tube 41, the clamping member 42 can be assembled from the proximal end of the receiving tube 41 in the direction of the position where the support platform 416 is located.

[0151] When the clamping member 42 has the Figure 4 shown structure, the connection steps of the connecting member 42 and the receiving tube 41 may include: first, at least a part of the first operating portion 422 passes from the inside out through the strip-shaped groove 415, and then a part of the clamping member 42, such as the bent corner portion 426, enters the gap from the proximal end of the gap between the first retaining member 417 and the second retaining member 418, and then at least a part of the connecting portion 423 is embedded in the retaining groove 4181 of the second retaining member 418. The second retaining member 418 can stop the connecting portion 423 to prevent the connecting portion 423 from entering the receiving cavity 411. Therefore, the clamping member 42 can be conveniently connected to the receiving tube 41.

[0152] Wherein, the bent corner portion 426 may be located between the first retaining member and the second retaining member and be supported by the support platform 416.

[0153] When the clamping member 42 is Figure 5 or Figure 6When in the structure shown, the receiving tube 41 further includes a third retaining member 419, the third retaining member 419 is spaced apart from the second retaining member 418, the third retaining member 419 defines a partial boundary of the first receiving cavity 4111, and the support platform 416 defines the distal boundary of the gap between the third retaining member 419 and the second retaining member 418, and the proximal end of the gap between the third retaining member 419 and the second retaining member 418 is open. The connection step of the connecting member 42 to the receiving tube 41 may include:

[0154] First, at least a part of the first operating portion 423 and the second operating portion 425 passes through the strip-shaped groove 415 from the inside to the outside, and then a part of the clamping member 42, such as the bent corner portion 426, enters the gap between the first retaining member 417 and the second retaining member 418 from the gap, and another part of the clamping member 42, such as another bent corner portion 426, enters the gap from the proximal end of the gap between the third retaining member 419 and the second retaining member 418, and then at least a part of the connecting portion 423 is embedded in the retaining groove 4181 of the second retaining member 418. Therefore, the clamping member 42 can be more conveniently connected to the receiving tube 41.

[0155] Please refer to Figure 1 and Figure 2 , the aerosol generating device further includes a power source 7 and a circuit board 8. The power source 7 is used to provide power for the heating element 2 to generate heat or to provide power for the magnetic field generator. The power source 7 can be any suitable battery. In one embodiment, the battery is a lithium-ion battery.
