Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically to an aerosol generation apparatus. Background Technology

[0002] Aerosol generating devices utilize the thermal effect of a heating element to heat aerosol generating products placed within its heating chamber, thereby generating aerosols without combustion. Currently, aerosol generating devices are generally only applicable to one type of aerosol generating product, and each aerosol generating product corresponds to a specific heating curve. Therefore, different heating curves and different aerosol generating devices are required when heating different types of aerosol generating products, which undoubtedly increases the user's operating costs and leads to a poor user experience. Utility Model Content

[0003] This application provides an aerosol generating device that is compatible with different types of aerosol generating products, thereby improving the user experience.

[0004] This application provides an aerosol generating device, including a housing, a heating body, a movable base, a rotating assembly, and a limiting bracket. The heating body is disposed within the housing and has a heating cavity for accommodating and heating the aerosol generating product to generate aerosol. The movable base is disposed within the housing and movably disposed on one side of the heating body, together with the heating body defining the heating cavity. At least a portion of the rotating assembly is disposed within the housing and movably connected to the movable base. The rotating assembly is capable of rotating about its own axis to drive the movable base to move along the axial direction of the heating cavity, thereby changing the extension length of the heating cavity. The rotating assembly has an assembly cavity. The limiting bracket is fixedly disposed within the housing, and at least a portion of the limiting bracket is inserted into the assembly cavity to restrict the movement of the rotating assembly along the axial direction of the heating cavity.

[0005] In an optional embodiment, the aerosol generating device further includes an active switch and a control board. The active switch is disposed on one side of the rotating assembly, and the rotating assembly can drive the active switch to switch to different states. The control board is electrically connected to both the active switch and the heating body, and is used to trigger the heating body to operate according to a preset heating curve corresponding to the state of the active switch.

[0006] In an optional embodiment, the rotating assembly includes a rotating disk and a linkage rod; the linkage rod has a first end and a second end disposed opposite to each other along its axial direction, the first end is threaded on the outside and is movably connected to the movable base, and the second end is connected to the rotating disk and forms the assembly cavity.

[0007] In an optional embodiment, the limiting bracket is provided with a first cavity and a second cavity continuously along the axial direction of the linkage rod from the first end to the second end. The inner diameter of the second cavity is smaller than the inner diameter of the first cavity, so as to form a stepped structure between the first cavity and the second cavity. A limiting protrusion is provided on the circumference of the second end. When the second end is inserted into the second cavity, the limiting protrusion is engaged with the stepped structure.

[0008] In an optional embodiment, the edge of the rotating disk is recessed radially inward to form a groove and a protrusion, the groove and the protrusion intersect to define a movement path, and the movable switch is movable along the movement path to achieve switching between different states.

[0009] In an optional embodiment, the movement path includes a middle position and a first limit position and a second limit position disposed on both sides of the middle position. When the active switch moves to the first limit position, the active switch is in a first state; when the active switch moves to the middle position, the active switch is in a second state; and when the active switch moves to the second limit position, the active switch is in a third state.

[0010] In an optional embodiment, the movement path is a parabola, an arc, or a broken line.

[0011] In an optional embodiment, a movable groove extends through one side of the outer casing, and a toggle lever is provided on the rotating assembly. The toggle lever passes through the movable groove and extends to the outside of the outer casing to drive the rotating assembly to rotate.

[0012] In an optional embodiment, the active switch includes one of a micro switch, a toggle switch, and an electromagnetic switch.

[0013] In an optional embodiment, the aerosol generating device further includes a mounting bracket, which is disposed outside the movable base and the rotating assembly. The mounting bracket has a movable track along the axial direction of the heating chamber, and the movable base has a movable block that is slidably connected to the movable track.

[0014] The aerosol generating device according to the above embodiments includes an outer shell, a heating body, a movable base, a rotating component, and a limiting bracket. The heating body has a heating cavity for accommodating and heating the aerosol-generated product. The movable base and the rotating component work together to change the extension length of the heating cavity, thereby enabling compatibility with different models and specifications of aerosol-generated products, improving the adaptability of the generating device, reducing user costs, and thus improving the user experience. Due to the setting of the limiting bracket, the rotating component can only rotate around its own axis and cannot move along the axis of the heating cavity, thereby effectively ensuring the stability of the internal structure of the production device and ensuring the consistency of the heating cavity extension length corresponding to the same specification of aerosol-generated product, thus ensuring the normal operation of the generating device and improving its service life.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0026] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0027] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0028] In existing aerosol generating devices, each model corresponds to one type of atomizing matrix. When switching to a different atomizing matrix, the corresponding aerosol generating device must be replaced. The same aerosol generating device cannot be compatible with two or more types of atomizing matrices, which undoubtedly increases the user's purchase cost and causes inconvenience for users when traveling. To solve this technical problem, this application provides the following specific solution.

[0029] This application provides an aerosol generating device (hereinafter referred to as the generating device), which can be used to heat the aerosol generating product A to generate an aerosol that can be inhaled and used by a user.

[0030] It should be noted that the term "aerosol" in this context refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used herein can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0031] As used herein, the term "aerosol-generating article A" refers to any suitable compound or mixture of compounds that facilitates the formation of aerosols (e.g., stable aerosols that are substantially resistant to thermal degradation at the operating temperature of the system) during use. Suitable aerosol-generating articles A are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate.

[0032] Aerosol-generating article A may include nicotine. Aerosol-generating article A may include water. Aerosol-generating article A may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Aerosol-generating article A may include propylene glycol. Aerosol-generating article A may include plant-based materials. Aerosol-generating article A may include homogeneous plant substrate. The homogeneous plant substrate may contain volatile compounds. These compounds may be released from aerosol-generating article A upon heating.

[0033] Please see Figures 1 to 9The generating device includes a housing 100, a heating body 200, a movable base 300, a rotating assembly 400, and a limiting bracket 500. The heating body 200 is the main structure in the generating device that performs the heating function. It is disposed within the housing 100 and is used to heat the aerosol generating product A to generate aerosol. The heating body 200 has a heating cavity 210 for accommodating the aerosol generating product A. The movable base 300 is disposed within the housing 100 and is movably disposed on one side of the heating body 200. Together with the heating body 200, it defines the heating cavity 210. When the aerosol generating product A is loaded into the heating cavity 210, the end of the movable base 300 abuts against the end of the aerosol generating product A to restrict and fix it. A fixed aerosol generating product A; at least a portion of the rotating component 400 is disposed within the outer casing 100 and is movably connected to the movable base 300. The rotating component 400 is capable of rotating around its own axis to drive the movable base 300 to move along the axis B of the heating chamber 210, thereby changing the extension length of the heating chamber 210; the rotating component 400 is provided with an assembly cavity 410; a limiting bracket 500 is fixedly disposed within the outer casing 100, and at least a portion of the limiting bracket 500 is inserted into the assembly cavity 410 to limit the movement of the rotating component 400 along the axis B of the heating chamber 210.

[0034] The outer shell 100 can be understood as a collection of related components that constitute the overall outer contour structure of the generating device. For example, the outer shell 100 can be assembled from one or more components, and corresponding assembly structures are provided inside the outer shell 100 or on its shell wall to assemble other components of the generating device into the outer shell 100. For example, the heating body 200, the movable base 300, and the rotating component 400 can be placed inside the outer shell 100. They can be assembled into a single structure and then assembled together inside the outer shell 100, or they can be placed sequentially inside the outer shell 100 and connected as a single unit. Of course, based on the functions of the heating body 200, the movable base, and the rotating component 400, at least a portion of the rotating component 400 is disposed inside the outer shell 100, and at least a portion is exposed outside the outer shell 100, so as to facilitate the rotation of the rotating component 400. The outer casing 100 prevents direct contact between the user and the high-temperature heating element 200 when the device is held in hand, thus avoiding burns. Simultaneously, the outer casing 100 also provides insulation, improving the thermal efficiency of the heating element 200. Furthermore, the outer casing 100 allows users to easily carry, move, operate, and use the device.

[0035] Generally, after molding, aerosol-generating product A is a slender cylindrical or near-cylindrical shape with a certain extension length. Along its extension length, aerosol-generating product A includes a functional section, an intermediate section, and a matrix section. During use, the matrix section is primarily heated and atomized to generate aerosols. Therefore, when loading aerosol-generating product A into the generating device, it is inserted along the axis B of the heating chamber 210, with the matrix section completely contained within the heating chamber 210 to ensure sufficient atomization of the matrix and avoid waste.

[0036] However, there are many different types of aerosol-generating products (A) in existing technologies, such as the widely used TEREA and NSCS. TEREA is a product under Philip Morris International's IQOS brand, offering multiple flavors, and is the dedicated aerosol-generating product A brand for the ILUMA generating device. NSCS (Nature Smoke Cigarettes, Nscs) uses a unique anaerobic heating technology, allowing the heating zone of the aerosol-generating product A to naturally generate aerosols in a low-oxygen state, which diffuses into the aerobic area, and then the aerosols are extracted through airflow. Compared to NSCS, TEREA is shorter and NSCS is longer. Since the heating chamber 210 in the generating device has a fixed length, in order to accommodate aerosol generated products A of different lengths, if the heating chamber 210 is set according to the longer aerosol generated product A, the heat utilization rate will be reduced. If it is set according to the shorter aerosol generated product A, the matrix segment of the longer aerosol generated product A cannot be completely accommodated in the heating chamber 210. Therefore, the existing generating device cannot simultaneously accommodate two or more specifications of aerosol generated product A, which increases the user's operating cost.

[0037] To solve the above problems, the length of the heating chamber 210 is adjusted by the cooperation of the movable base 300 and the rotating component 400, thereby achieving compatibility with aerosol-generated products A of different specifications. Specifically, the movable base 300 and the heating body 200 together define the heating chamber 210, and the movable base 300 can move along the axis B of the heating chamber 210 under the action of the rotating component 400, thereby changing the extension length of the heating chamber 210, so that the heating chamber 210 can be used for aerosol-generated products A of different specifications.

[0038] To further ensure the movement of the movable base 300 along the axis B of the heating chamber 210 and reduce the influence of movement in other directions, a limiting bracket 500 is provided inside the outer shell 100. At least a portion of the limiting bracket 500 can be inserted into the assembly cavity 410 of the rotating component 400 to cooperate with the outer shell 100 to restrict the movement of the rotating component 400 along the axis B of the heating chamber 210. This ensures that the rotating component 400 can only rotate around its own axis, thereby driving the movable base 300 to move stably along the axis B of the heating chamber 210. It also ensures that the extension length of the heating chamber 210 corresponding to the same specification of aerosol generated product A is consistent throughout the movement of the movable base 300. This avoids situations where the installation position of the same specification of aerosol generated product A is inconsistent due to inconsistent extension lengths, resulting in uneven atomization of the matrix section or the generation of odors from other structures being baked. This ensures the normal operation of the generating device and extends its service life.

[0039] In practical applications, the movable base 300 and the heating cavity 210 are coaxially arranged, which effectively ensures that the length of the heating cavity 210 can be changed when the movable base 300 moves along the axial direction B of the heating cavity 210. Furthermore, the rotating component 400 is also coaxially arranged with the movable base 300 and the heating cavity 210, which simplifies operation and structure.

[0040] In some embodiments, the aerosol generating device further includes an active switch 600 and a control board 700. The active switch 600 is disposed on one side of the rotating assembly 400. When the rotating assembly 400 drives the movable base 300 to move, it can synchronously drive the active switch 600 to switch to different states. The control board 700 is electrically connected to both the active switch 600 and the heating body 200, and is used to trigger the heating body 200 to operate according to a preset heating curve corresponding to the state of the active switch 600. Specifically, the control board 700 is provided with a corresponding control circuit. The active switch 600 and the heating body 200 are both electrically connected to the control circuit. The active switch 600 can be the input terminal of the control circuit, and the heating body 200 can be the output terminal of the control circuit. When the active switch 600 is driven to different states by the rotating assembly 400, the control circuit outputs a circuit signal corresponding to that state, triggering the input of different currents or voltages at the heating body 200, changing the heating power or heating temperature at the heating body 200, thereby triggering the heating body 200 to operate according to the preset heating curve corresponding to the state of the active switch 600.

[0041] In practical applications, since different aerosol-generated products A not only have different lengths, but also correspond to different preset heating curves, the rotation of the rotating component 400 synchronously drives the movable base 300 to move upward along its axis and the state switching of the movable switch 600. Therefore, the movable base 300 can be set at one end of the axial direction of the rotating component 400, and the movable switch 600 can be set on one side of the circumference of the rotating component 400.

[0042] Please see Figure 3 and Figure 4 In some embodiments, the rotating assembly 400 includes a rotating disk 420 and a linkage rod 430. The linkage rod 430 has a first end 431 and a second end 432 arranged opposite each other along its axial direction. The first end 431 is threaded on the outside and is movably connected to the movable base 300. Since the first end 431 of the linkage rod 430 is threaded on the outside and the movable base 300 is movably connected to the first end 431, the movable base 300 is driven to move along the axis B of the heating chamber 210 by means of the rotation of the rotating assembly 400, and linear reciprocating motion can be realized. This allows the heating chamber 210 to be switched to different lengths repeatedly. Moreover, the mechanical principle of this structure is mature and helps to simplify the structure and processing of the production device.

[0043] In some embodiments, the second end 432 of the linkage rod 430 is connected to the rotating disk 420 to form an assembly cavity 410. At least a portion of the limiting bracket 500 is inserted into the assembly cavity 410 and is interference-fitted with the assembly cavity 410 to limit the rotation disk 420. In this embodiment, the linkage rod 430 and the rotating disk 420 can be an integrally formed structure.

[0044] In other embodiments, to facilitate the assembly of the rotating disk 420 and the linkage rod 430, the rotating disk 420 and the linkage rod 430 can be separate structures. The rotating disk 420 is hollow in the middle, and the linkage rod 430 is inserted into the rotating disk 420, forming an assembly cavity 410 between the rotating disk 420 and the linkage rod 430 to install the limiting bracket 500. Specifically, the linkage rod 430 and the rotating disk 420 can be detachably connected by a threaded connection or a snap-fit ​​connection. Of course, in other embodiments, connecting parts, such as screws or bolts, can be provided to connect the linkage rod 430 and the rotating disk 420.

[0045] Please continue reading. Figure 4In some embodiments, the limiting bracket 500 is provided with a first cavity 510 and a second cavity 520 continuously along the axial direction of the linkage rod 430 from the first end 431 to the second end 432. The inner diameter of the second cavity 520 is smaller than the inner diameter of the first cavity 510, so as to form a stepped structure 530 between the first cavity 510 and the second cavity 520. A limiting protrusion 440 is provided on the circumference of the second end 432. When the second end 432 is inserted into the second cavity 520, the limiting protrusion 440 is engaged with the stepped structure 530. Through the cooperation of the limiting protrusion 440 and the stepped structure 530, the limiting of the rotating disk 420 and the linkage rod 430 in the direction of axis B of the heating cavity 210 is further realized. Specifically, the limiting protrusion 440 can be formed as an annular protrusion around the circumference of the second end 432, or it can be a protrusion, protrusion point or protrusion strip symmetrically arranged on both radial sides of the second end 432. The cross-section of the limiting protrusion 440 in the direction of axis B of the heating cavity 210 can be semi-circular, triangular, rectangular or other irregular structure.

[0046] Please see Figure 5 and Figure 6 In some embodiments, the edge of the rotating disk 420 is recessed radially inward to form a groove 421 and a protrusion 422. The groove 421 and the protrusion 422 intersect to define a movement path 423. The active switch 600 can move along the movement path 423 to switch between different states. Specifically, the active switch 600 can reciprocate along the movement path 423 under the drive of the rotating assembly 400 (or the rotating disk 420). When it moves to different positions on the movement path 423, the active switch 600 switches to different states accordingly.

[0047] Please continue reading. Figure 6 and Figure 7In some embodiments, the moving path 423 includes an intermediate position 4231 and a first limit position 4232 and a second limit position 4233 disposed on both sides of the intermediate position 4231. When the active switch 600 moves to the first limit position 4232, the active switch 600 is in a first state; when the active switch 600 moves to the intermediate position 4231, the active switch 600 is in a second state; and when the active switch 600 moves to the second limit position 4233, the active switch 600 is in a third state. Specifically, in the first state, the movable base 300 is located in the first position, the heating chamber 210 has a first extension length, and the heating body 200 operates according to a first preset heating curve, which is applicable to the first type of aerosol generating product A; in the second state, the movable base 300 is located in the second position, the heating chamber 210 has a second extension length, and the heating body 200 can be used to operate or not operate according to the second preset heating curve for the second type of aerosol generating product A; in the third state, the movable base 300 is located in the third position, the heating chamber 210 has a third extension length, and the heating body 200 operates according to the third preset heating curve, which is applicable to the third type of aerosol generating product A.

[0048] In practical applications, since the commonly used aerosol generating products A are TEREA and NSCS as mentioned above, which correspond to two different extension lengths of the heating chamber 210, the active switch 600 can be set to be inactive when it is in the second state. Of course, when the types of aerosol generating products A are increased to three or more, the moving path 423 can correspond to three or more positions, and these three or more positions correspond to three or more states of the active switch 600, each of which is an active state, and can be used to heat one type of aerosol generating product A.

[0049] In some embodiments, the movement path 423 is a parabola, an arc, or a broken line. Each parabola, arc, or broken line has at least one lowest position, which is the middle position 4231. The two ends of the movement path 423 are the first limit position 4232 and the second limit position 4233. The parabola, arc, or broken line is an unclosed structure with an opening facing the active switch 600. Correspondingly, its lowest position is the position closest to the center of the rotating disk 420. Specifically, when the movement path 423 where the groove 421 and the protrusion 422 intersect is a parabola, its shape can be a sine or cosine function graph of one period. When the movement path 423 is an arc, the arc can be a semicircle or a "U" shape. The movement path 423 can also be a broken line. For example, the movement path 423 is a two-broken line structure, roughly forming a "V" shape. The opening of the "V" shape faces the active switch 600, its closed end is the middle position 4231, and the ends of the opening are the first limit position 4232 and the second limit position 4233, as shown. Figure 7 As shown, in the first state, the active switch 600 is in the first limit position 4232; in the second state, the active switch 600 is in the middle position 4231; and in the third state, the active switch 600 is in the second limit position 4233.

[0050] Please see Figure 9 In some embodiments, a movable groove 110 extends through one side of the outer casing 100, and a toggle lever 450 is provided on the rotating assembly 400. The toggle lever 450 passes through the movable groove 110 and extends to the outside of the outer casing 100 to drive the rotating assembly 400 to rotate. Specifically, the toggle lever 450 is set on the circumference of the rotating disk 420 and extends to the outside of the outer shell 100 through the movable groove 110. The movable groove 110 is an arc-shaped groove structure set along the outer shell 100. The angle corresponding to the arc-shaped groove is the same as the angle of the moving path 423. The two ends of the arc-shaped groove correspond to the first limit position 4232 and the second limit position 4233 of the moving path 423, and the middle part of the arc-shaped groove corresponds to the middle position 4231 of the moving path 423. Thus, by setting the toggle lever 450, not only can the rotating component 400 be driven, and the movable base 300 and the movable switch 600 be moved, but the current state of the generating device can also be conveniently viewed from the outside of the outer shell 100, i.e., adapting to the first aerosol generating product A or the second aerosol generating product A.

[0051] In some embodiments, the active switch 600 includes one of a micro switch, a toggle switch, and an electromagnetic switch. The active switch 600 can be activated by external force and switched to different states. In specific applications, it is not limited to the above three types; other active switches 600 that can achieve this purpose may also be used.

[0052] In some embodiments, the aerosol generating device further includes a mounting bracket 800, which is disposed outside the movable base 300 and the rotating assembly, and is also disposed inside the outer casing 100. The mounting bracket 800 abuts against the outer casing 100 and the heating body 200, thereby preventing movement of the components within the outer casing 100. A movable track 810 is provided on the mounting bracket 800 along the axis B of the heating cavity 210, and a movable block 310 is provided on the movable base 300. The movable block 310 is slidably connected to the movable track 810. The movable track 810 further limits the movement trajectory of the movable base 300, ensuring stable operation along the axis B of the heating cavity 210.

[0053] In some embodiments, the generating device further includes a display screen 900, which is electrically connected to the control board 700. The display screen 900 can not only display the status of the active switch 600, but also display the preset heating curve of the heating body 200, so that the user can understand the working status of the generating device.

[0054] Specifically, when the active switch 600 is in the second state (fully open state), the active base 300 is in the second position, the heating cavity 210 has a second extension length, the control board 700 can send a signal of "0", and the display screen 900 does not display a symbol. At this time, the generation state is not working. After the clockwise rotating component 400 rotates, it drives the active base 300 to move in the direction away from the heating body 200 along the axis B of the heating cavity 210, so that the active base 300 is in the first position, the heating cavity 210 has a first extension length, the active switch 600 switches to the first state (closed state), the control board 700 can send a signal of "1", and the display screen 900 displays a "CC" symbol. At this time, it is applicable to TEREA, and it is heated by the first preset heating curve.
