Specific embodiments

[0034] The present application will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of these features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0035] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are essential components and / or sequences.

[0036] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0037] In existing aerosol generating devices, one model of the device corresponds to the use of one type of aerosol generating substrate. When replacing different aerosol generating substrates, it is necessary to replace the corresponding aerosol generating device. The same aerosol generating device cannot be compatible with two or more types of aerosol generating substrates, which undoubtedly increases the purchase cost for users and also causes trouble in carrying and using for users when they go out. To solve this technical problem, the present application provides the following specific solutions.

[0038] The present application provides an aerosol generating device (hereinafter referred to as the generating device), which can be used to heat an aerosol generating substrate A to generate an aerosol that can be used.

[0039] It should be noted that the aerosol referred to in the terms means a dispersion of solid particles or liquid particles in a gas. As used herein, "aerosol" generally can be used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0040] As used herein, the term "aerosol generating substrate A" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that substantially resists thermal degradation at the operating temperature of the system) during use. Suitable aerosol generating substrates 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 glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0041] The aerosol - generating substrate A may include nicotine. The aerosol - generating substrate A may include water. The aerosol - generating substrate A may include glycerol (also known as propanetriol) which has a boiling point higher than that of nicotine. The aerosol - generating substrate A may include propylene glycol. The aerosol - generating substrate A may include plant - based materials. The aerosol - generating substrate A may include a homogeneous plant matrix material. The homogeneous plant matrix material may contain volatile compounds. These compounds may be released from the aerosol - generating substrate A when heated.

[0042] Reference Figures 1 to 12 , the generating device includes a housing 100, a receiving channel 200, a heating component 300, a contact member 400, and a driving component 500. The receiving channel 200 is formed within the housing 100. The receiving channel 200 has opposite first and second ends 210 and 220. The first end 210 is for inserting the aerosol - generating substrate A, and the receiving channel 200 is for placing the aerosol - generating substrate A. The heating component 300 is configured to form a part of the receiving channel 200. The contact member 400 is disposed at the second end 220. The contact member 400 is configured to contact the aerosol - generating substrate A. The driving component 500 is configured to drive the contact member 400 to move so as to adjust the distance between the contact member 400 and the heating component 300.

[0043] Since the position movement of the contact member 400 can adjust the distance between the contact member 400 and the heating component 300, thus defining different insertion depths of the aerosol - generating substrate A into the receiving channel 200 (i.e., the distance between the end face of the first end 210 and the end face of the contact member 400 facing the first end 210). Since different models of the aerosol - generating substrate A have different sizes (especially different lengths), the generating device can be compatible with different models of the aerosol - generating substrate A, improving the adaptability of the generating device and also reducing the usage cost for customers.

[0044] Please refer to Figures 3 to 5 , the driving component 500 includes a driving member 510 and a guiding member 520. The contact member 400 is movably connected to the driving member 510. The contact member 400 is movably connected to the guiding member 520. The guiding member 520 is provided with a spiral track 521. The contact member 400 is provided with a slider 410. The driving member 510 is provided with a guiding groove 5121. The slider 410 passes through the guiding groove 5121 and is movably connected to the spiral track 521.

[0045] Specifically, the abutting member 400, the driving member 510, and the guiding member 520 are coaxially arranged. The driving member 510 and the guiding member 520 are disposed substantially along the axial direction. The driving member 510 is sleeved on the abutting member 400. At least a part of the structure of the abutting member 400 is disposed inside the driving member 510, and the two can slide relative to each other and are guided in motion through the guiding groove 5121. The guiding member 520 is disposed outside the abutting member 400 and the driving member 510. When the driving member 510 rotates about its own axis, the abutting member 400 moves along the spiral track 521 on the guiding member 520 and is simultaneously guided by the guiding groove 5121 on the driving member 510, thereby changing the distance between the abutting member 400 and the heating assembly 300 to adapt to the insertion depths of aerosol-generating substrates A of different models.

[0046] Generally, based on different material forms, the aerosol-generating substrate A can be packaged in a shaped package or disposed in a container. Generally, after being formed, the aerosol-generating substrate A has a certain extended length. Along the direction of its extended length, the aerosol-generating substrate A includes a suction section, a diversion section, and a matrix section. During use, the matrix section is mainly heated and atomized to generate aerosol. Therefore, when the aerosol-generating substrate A is inserted into the accommodation channel 200, the aerosol-generating substrate A is inserted along the direction from the first end 210 to the second end 220, and at least the matrix section is ensured to be disposed in a part of the accommodation channel 200 formed by the heating assembly 300.

[0047] However, there are many different types of aerosol-generating substrates A in the prior art, such as the widely used TEREA and NSCS. TEREA is a product under the IQOS brand of Philip Morris International and has multiple flavors. It is a dedicated aerosol-generating substrate A brand for the ILUMA generating device. NSCS cartridges: (Nature Smoke Cigarettes, Nscs) adopt a unique anaerobic heating technology, enabling the aerosol-generating substrate A to naturally generate aerosol in a low-oxygen state in the heating area, diffuse into the aerobic area, and then extract the aerosol through the intake air flow. Compared with TEREA, TEREA is shorter in length and NSCS is longer. After using them together in the same generating device, since the length of the accommodation channel 200 remains unchanged, some matrix sections of different models of aerosol-generating substrates A cannot be heated and atomized after being inserted, resulting in waste.

[0048] Please refer to Figure 1 and Figure 2, the driving component 500 can drive the abutting component 400 to move in the direction from the first end 210 to the second end 220, so that the abutting component 400 reciprocates between the first position and the second position; at the first position, there is a first distance S1 between the heating component 300 and the abutting component 400; at the second position, there is a second distance S2 between the heating component 300 and the abutting component 400; the second distance S2 is greater than the first distance S1. The abutting component 400 reciprocates between the first position and the second position, that is, the abutting component 400 can reciprocate between the regions defined by the first position and the second position, and can adapt to at least two or more models of the aerosol generation substrate A.

[0049] It should be noted that the distances between the heating component 300 and the abutting component 400 mentioned above refer to the lengths of the connecting lines between the midpoints of the end faces of the heating component 300 facing the second end 220 and the midpoints of the end faces of the abutting component 400 facing the first end 210. The heating component 300 and the abutting component 400 are coaxially arranged, and this distance is also the straight-line distance between the two end faces.

[0050] Of course, in order to ensure the stable position of the abutting component 400, in one embodiment, the abutting component 400 can only move to the first position or the second position, and the slider 410 moves to two extreme positions in the trajectory defined by the spiral track 521, so that the abutting component 400 is positioned at the first position or the second position.

[0051] Please refer to Figures 4 to 6 , the driving member 510 includes a driving part 511 and a transmission part 512, and the driving part 511 is connected to the transmission part 512; the abutting component 400 is movably connected to the transmission part 512; a guiding groove 5121 is provided at one end of the transmission part 512 away from the driving part 511; the driving part 511 drives the transmission part 512 to rotate around the axis of the transmission part 512, driving the abutting component 400 to move along the guiding groove 5121, so that the abutting component 400 reciprocates between the first position and the second position.

[0052] Please refer to Figure 6 and Figure 7 , the driving part 511 and the transmission part 512 are coaxially arranged; the driving part 511 is detachably connected to the transmission part 512; a first clamping part 5111 is provided on the side of the driving part 511 opposite to the transmission part 512, and a second clamping part 5122 is provided on the side of the transmission part 512 opposite to the driving part 511, and the first clamping part 5111 and the second clamping part 5122 are clamped to realize the clamping of the driving part 511 and the transmission part 512. One of the first clamping part 5111 and the second clamping part 5122 is a convex structure, and the other is a groove 5123 structure, and the groove 5123 structure is engaged with the convex structure, which is convenient for the assembly, disassembly and maintenance of the driving part 511 and the transmission part 512.

[0053] Of course, in other embodiments, the driving part 511 and the transmission part 512 may also be integrally formed structures, which can reduce parts and costs.

[0054] Please refer to Figures 9 to 11 , the aerosol generating device further includes a detection switch 600. When the transmission part 512 rotates, it can drive the detection switch 600 to switch between a first detection position and a second detection position; at the first detection position, the transmission part 512 presses the detection switch 600, and the abutting part 400 moves to the first position; at the second detection position, the transmission part 512 releases the detection switch 600, and the abutting part 400 moves to the second position.

[0055] In one embodiment, a groove 5123 is provided at one end of the transmission part 512 close to the driving part 511. At the second detection position, at least part of the structure of the detection switch 600 is disposed in the groove 5123.

[0056] Please refer to Figures 9 to 11 , the detection switch 600 includes a movable part 610 and a movable groove 620. At the first detection position, the movable part 610 is disposed in the movable groove 620; at the second detection position, the movable part 610 extends out of the movable groove 620, and at least part of the structure of the movable part 610 is disposed in the groove 5123.

[0057] In one embodiment, the guiding groove 5121 is a linear guiding groove 5121 extending along the direction from the second end 220 to the first end 210, so that the abutting part 400 moves stably in a straight line along the linear guiding groove 5121 and ensures smooth movement.

[0058] Please refer to Figure 4 , the slider 410 includes a first protrusion 411 and a second protrusion 412 symmetrically arranged along the axis of the abutting part 400, and the spiral track 521 includes a first spiral groove 5211 and a second spiral groove 5212 symmetrically arranged along the axis of the guiding part 520. The first protrusion 411 is movably connected to the first spiral groove 5211, and the second protrusion 412 is movably connected to the second spiral groove 5212; the trajectories of the first spiral groove 5211 and the second spiral groove 5212 are both cylindrical helical lines around the side wall of the guiding part 520.

[0059] It should be noted that the definition of a cylindrical helix is that a moving point moves uniformly along the generatrix of a cylindrical surface, and at the same time, the generatrix rotates uniformly around the axis of the cylindrical surface. The trajectory of this compound movement of the point is called a cylindrical helix, which is a common spiral curve.

[0060] In one embodiment, the heating assembly 300 includes a heating tube body 310 and a heating element 320. The heating tube body 310 has a hollow structure, and its inner cavity forms part of the accommodating channel 200. The heating element 320 is disposed in a fitting manner on the inner side wall of the heating tube body 310. The heating element 320 is energized to generate heat for heating and baking the aerosol generating substrate A.

The mounting bracket 700 includes a mounting base 710 and a connecting member 720. The mounting base 710 and the connecting member 720 are sequentially arranged along the direction from the first end 210 to the second end 220. The installation space 730 is formed within the mounting base 710, and the connecting member 720 is used to achieve the fixed connection between the mounting base 710 and the outer housing 100.

[0062] The generating device further includes a main control assembly 800 disposed within the outer housing 100. The main control assembly 800 includes a battery and a control component. The battery can provide the power required for the heating assembly to operate, and the control component can adjust the power when the battery is working. The outer housing 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 housing 100 can be assembled by combining one or more components, and corresponding assembly structures are provided inside or on the shell wall of the outer housing 100 to assemble other components of the generating device to the outer housing 100. For example, the control circuit board, battery, detection circuit, etc. in the main control assembly can be assembled inside the outer housing 100, and the operation buttons of the main control assembly 800 can be installed on the outer housing 100 in a manner that is exposed outside the outer housing 100; with the help of the outer housing 100, users can conveniently carry, move, operate, and use the generating device.

[0063] Further, the detection switch is electrically connected to the detection circuit in the control component. The detection circuit is used to detect the position of the detection switch 600 and output a circuit signal corresponding to the position of the detection switch 600 to trigger a working temperature corresponding to the circuit signal for heating different types of aerosol generating substrates.

[0064] The above uses specific examples to elaborate on the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the technical field to which the present application pertains, based on the idea of the present application, several simple deductions, deformations, or substitutions can also be made.
