DETAILED DESCRIPTION

[0025] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods.

[0026] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0027] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0028] In the existing aerosol generating devices, one type of device corresponds to one type of atomizing matrix. When a different atomizing matrix is ​​used, the corresponding aerosol generating device needs to be replaced. The same aerosol generating device is not compatible with two or more types of atomizing matrices, which undoubtedly increases the purchase cost of the user and also brings troubles to the user in carrying and using when the user goes out. In order to solve this technical problem, the present application provides the following specific solutions.

[0029] refer to Figures 1 to 9 The present application provides an aerosol generating device (hereinafter referred to as the generating device) which can be used to heat the atomizing matrix 400 to generate an aerosol that can be used.

[0030] It should be noted that the term aerosol refers to a dispersion of solid particles or liquid particles in a gas. As used herein, "aerosol" can generally be used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form to an inhalable form containing suspended solid or liquid drug particles.

[0031] As used herein, the term "atomizing substrate 400" 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 atomizing substrates 400 are well known in the art and include, but are not limited to: polyols, such as triethylene glycol, 1,3-butylene glycol, 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.

[0032] The atomizing matrix 400 may include nicotine. The atomizing matrix 400 may include water. The atomizing matrix 400 may include glycerine (also known as glycerol) having a higher boiling point than nicotine. The atomizing matrix 400 may include propylene glycol. The atomizing matrix 400 may include plant-based materials. The atomizing matrix 400 may include a homogenized plant matrix material. The homogenized plant matrix material may contain volatile compounds. These compounds may be released from the atomizing matrix 400 when heated.

[0033] refer to Figure 1 The generating device comprises an outer shell 100, a main control assembly 200 and an atomizer 300, wherein the main control assembly 200 and the atomizer 300 are arranged in the outer shell 100, and the main control assembly 200 comprises a battery 210 and a control assembly 220, wherein the battery 210 can provide the atomizer 300 with the power required for operation, and the control assembly 220 can adjust the power of the battery 210 when it is working. The outer shell 100 can be understood as a collection of related components constituting the overall outer contour structure of the generating device, for example, the outer shell 100 can be constructed by combining one or more components, and a corresponding assembly structure is arranged inside or on the shell wall of the outer shell 100, so that other components of the generating device can be assembled in the outer shell 100, for example, the control circuit board and the battery 210 in the main control assembly 200 can be assembled inside the outer shell 100, and the operation buttons of the main control assembly 200 can be installed on the outer shell 100 in a manner of being exposed to the outer shell 100; with the help of the outer shell 100, the user can conveniently carry, move, operate and use the generating device.

[0034] refer to Figure 2 and 3 The atomizer 300 includes a mounting bracket 310, a movable member 320 and a driving member 330. The mounting bracket 310 has a mounting axis ( Figure 1 The mounting bracket 310 has a accommodating space 311 therein, and the accommodating space 311 is used to accommodate the atomizing matrix 400. The movable member 320 is movably arranged in the accommodating space 311, and the accommodating space 311 is divided into a heating chamber 3111 and an adjusting chamber 3112 along the direction of the mounting axis. The heating chamber 3111 is used to heat the atomizing matrix 400 to atomize it to form an aerosol. At least part of the structure of the atomizing matrix 400 is arranged in the heating chamber 3111. The driving member 330 is arranged on a side of the movable member 320 away from the atomizing matrix 400. The driving member 330 can reciprocate in a direction perpendicular to the mounting axis, and drive the movable member 320 to reciprocate in the direction of the mounting axis, so as to adjust the extension length of the adjusting chamber 3112 and the heating chamber 3111 along the direction of the mounting axis.

[0035] The mounting bracket 310 is arranged in the outer shell 100. The mounting bracket 310 is a symmetrical structure with a mounting axis in the center. The internal accommodating space 311 extends along the mounting axis and is also a symmetrical structure. In the extension direction of the mounting axis, the accommodating space 311 has an extension length. The atomizing matrix 400 and the movable part 320 can be distributed along the extension length. One end of the atomizing matrix 400 contacts the movable part 320, so that the movable part 320 and part of the cavity wall of the accommodating space 311 enclose a space for placing the atomizing matrix 400. Since the atomizing matrix 400 needs to be heated and atomized during use, the space is specified as a heating chamber 3111, and the remaining part of the accommodating space 311 is specified as an adjustment chamber 3112.

[0036] Usually, based on the different material forms, the atomized matrix 400 can be packaged by packaging materials, or it can be arranged in a container. Generally, the atomized matrix 400 has a certain extension length after molding. Along the direction of its extension length, the atomized matrix 400 includes a suction section 410, a flow guide section 420 and a matrix section 430. When used, the matrix section 430 is mainly heated and atomized to generate an aerosol. Therefore, when the atomized matrix 400 is arranged in the mounting bracket 310, the atomized matrix 400 is inserted into the heating chamber 3111 along the axial direction of the installation, and at least the matrix section 430 is ensured to be arranged in the heating chamber 3111.

[0037] However, there are many different types of atomizing substrates 400 in the prior art, such as the widely used TEREA and NSCS. TEREA is a product under the IQOS brand of Philip Morris International, with multiple flavors. It is a dedicated atomizing substrate 400 brand for ILUMA generation devices. NSCS cartridges: (Nature Smoke Cigarettes, Nscs) use a unique anaerobic heating technology to enable the heating area of ​​the atomizing substrate 400 to naturally produce aerosols under low oxygen conditions, diffuse to the aerobic area, and then extract the aerosols through air intake circulation. Compared with TEREA and NSCS, TEREA is shorter and NSCS is longer. After the two are shared in the same generation device, since the overall extension length of the accommodating space 311 remains unchanged, if the length of the heating chamber 3111 remains unchanged, it may cause the installed matrix segment 430 to have a part of the structure arranged outside the heating chamber 3111, resulting in part of the matrix segment 430 being unable to be heated and atomized, thereby causing waste.

[0038] By movably arranging the movable part 320 in the accommodating space 311 and moving the movable part 320 along the direction of the installation axis, it means that the partial structure constituting the heating chamber 3111 can be adjusted, so that the extension length of the heating chamber 3111 finally formed in the direction of the installation axis can be adjusted, and it can adapt to atomization matrices 400 of different sizes and types (extension lengths), thereby improving the compatibility and application range of the entire generating device, and making it convenient for users to experience different flavors on one generating device.

[0039] It should be further explained that, based on the moving direction of the movable part 320, the present embodiment is mainly suitable for being compatible with a variety of atomizing matrices 400 with different extension lengths. In other embodiments, if it is necessary to adapt to atomizing matrices 400 with different widths or thicknesses, it can also be achieved by adjusting the position of the movable part 320 and adjusting the moving direction to deform it. This deformation is relatively simple and will not be elaborated here.

[0040] refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The movable member 320 has a first inclined surface 321, and the driving member 330 has a second inclined surface 331. The first inclined surface 321 is tightly abutted against the second inclined surface 331. The first inclined surface 321 and the second inclined surface 331 can slide against each other, and the second inclined surface 331 can squeeze the first inclined surface 321 to make a linear reciprocating motion along the direction of the installation axis, so that the movable member 320 can make a linear reciprocating motion along the direction of the installation axis.

[0041] The movable member 320 is composed of a first portion in contact with the driving member 330 and a second portion enclosed with the inner wall of the mounting bracket 310 to form a heating chamber 3111. The first portion and the second portion may be an integral structure or two independent components. The first portion and the second portion are combined to form the movable member 320. Since a portion of the structure of the movable member 320 forms the heating chamber 3111, it will be in contact with high temperature. The entire portion of the movable member 320 is made of a high temperature resistant material. Of course, in order to save costs, only the first portion may be made of a high temperature resistant material.

[0042] In one embodiment, the generating device has a first state and a second state, referring to Figure 2 and Figure 3 The driving member 330 has a first position and a second position. When the driving member 330 is in the first position, the movable member 320 is located at the first heating position and can heat the first type of atomized substrate 400 (such as TEREA). When the driving member 330 is in the second position, the movable member 320 is located at the second heating position and can heat the second type of atomized substrate 400 (such as NSCS).

[0043] Based on the usage habits of the generating device, the mounting axis of the mounting bracket 310 is a straight line arranged along the vertical direction, and the movable member 320 and the driving member 330 are arranged in sequence along the vertical direction. That is, the movable member 320 is roughly arranged above the driving member 330, and in a natural state, the movable member 320 has the weight to move downward due to its own weight.

[0044] Since in the first position, the second inclined surface 331 gives an upward squeezing force to the first inclined surface 321 to support the movable part 320 to overcome its own weight and avoid moving downward, when the driving part 330 switches from the first position to the second position, the second inclined surface 331 moves synchronously, and the squeezing force of the second inclined surface 331 on the first inclined surface 321 disappears instantly (this is because after the second inclined surface 331 moves, it is not in contact with the first inclined surface 321 for a moment), and the movable part 320 moves downward under its own weight, so that the length of the heating chamber 3111 increases, and it can adapt to the second type of atomization matrix 400 with a larger length (such as NSCS); when the driving part 330 switches from the second position to the first position, the second inclined surface 331 moves synchronously, and provides an upward squeezing force to the first inclined surface 321, so that the movable part 320 can move upward along the direction of the installation axis, and the length of the heating chamber 3111 is reduced, which can adapt to the first type of atomization matrix 400 with a smaller length (such as TEREA).

[0045] Of course, in other embodiments, the movable part 320 can be directly pushed to realize the linear reciprocating motion of the movable part 320 along the direction of the installation axis. For example, a linear motor or cylinder that can provide linear power can be added, and the existing linear motor and cylinder can adjust their own stroke, so that the movable part 320 can be adjusted to move to different positions. Or, for example, a plurality of (including two or more) limit buckles are set in the mounting bracket 310 along the direction of its installation axis, and the movable part 320 is manually pushed to different limit buckles to realize that the movable part 320 is pushed and limited to different positions.

[0046] refer to Figure 5 In order to limit and guide the movement of the movable part 320 to avoid instability during movement and ultimately affect the heating and atomization effect of the atomized matrix 400, a movable track 312 is provided on the inner wall of the mounting bracket 310. The movable track 312 extends in the direction from the mounting axis. A movable slider 322 is provided on the side of the movable part 320. The movable track 312 is a groove structure that matches the size of the movable slider 322. The movable slider 322 is slidably set on the movable track 312. When the movable part 320 moves, it can move on the movable track 312 along with the movable slider 322.

[0047] Of course, in other embodiments, the design positions of the moving track 312 and the moving slider 322 can be reversed. For example, the moving track 312 is arranged on the movable member 320 , and the moving slider 322 is arranged on the mounting bracket 310 .

[0048] refer to Figure 8 and Fig. 9 The atomizer 300 further includes a mounting base 340, which is disposed at one end of the mounting bracket 310. A limiting groove 341 is disposed on the mounting base 340, and the limiting groove 341 extends in a direction perpendicular to the mounting axis. One end of the driving member 330 is movably disposed in the limiting groove 341, and the limiting groove 341 is used to limit the position of the driving member 330. If the driving member 330 has a first position and a second position, the two extreme positions of the extending direction of the limiting groove 341 are the first position and the second position, which facilitates the positioning of the driving member 330.

[0049] refer to Figure 4 The atomizer 300 also includes a detection circuit 350 and a lever 360. The lever 360 is connected to the driving member 330. The driving member 330 can drive the lever 360 to switch between different positions. The detection circuit 350 is used to detect the position of the lever 360 and output a circuit signal corresponding to the position of the lever 360. The detection circuit 350 is also electrically connected to the control component 220, and can trigger the control component 220 to output an operating temperature corresponding to the circuit signal, so as to heat and atomize different types of atomization substrates 400.

[0050] The lever 360 can also be replaced by a toggle switch, a detection switch, a micro switch, a push button switch, a magnetic induction switch, and other forms.

[0051] In one embodiment, the lever 360 has a first detection position and a second detection position. When the driving member 330 is in the first position, the lever 360 is located in the first detection position, the movable member 320 is located in the first heating position, and the heating chamber 3111 has a first heating length S1 (reference Figure 2 ), the detection circuit 350 outputs a first circuit signal corresponding to the first detection position, and triggers the control component 220 to output a first operating temperature (which may also be a combustion curve) corresponding to the first circuit signal, and the first operating temperature can heat the atomized first type of atomized matrix 400; when the driving member 330 is in the second position, the lever 360 is located at the second detection position, the movable member 320 is located at the second heating position, and the heating chamber 3111 has a second heating length S2 (reference Figure 3 ), the detection circuit 350 outputs a second circuit signal corresponding to the second detection position, and triggers the control component 220 to output a second operating temperature (which can also be a combustion curve) corresponding to the second circuit signal, and the second operating temperature can heat the atomized second type of atomization matrix 400.

[0052] In one embodiment, the first heating length S1 and the second heating length S2 are the distances between the top of the movable part 320 and the top of the heating chamber 3111 (the uppermost part when placed vertically according to usage habits), and the value of S1 is greater than the value of S2. The heating lengths correspond to the lengths of the matrix segments 430 of different types of atomization matrices 400.

[0053] Of course, in other embodiments, the lever 360 may also be provided with multiple detection positions, and accordingly may be compatible with multiple types of atomized substrates 400. The manner and principle of the control component 220 outputting the operating temperature corresponding to the circuit signal has been disclosed in other existing patent documents, and will not be described in detail here.

[0054] In one embodiment, a mounting groove 332 is provided on the side of the driving member 330, and the lever 360 is disposed in the mounting groove 332. The driving member 330 can synchronously drive the lever 360 to reciprocate in a direction perpendicular to the mounting axis so that the lever 360 can switch to different positions.

[0055] In one embodiment, a heating element 370 of a cylindrical structure is provided in the heating chamber 3111, and the heating element 370 extends in the direction of the installation axis to heat the atomizing matrix 400. The heating element 370 can be arranged in contact with the inner wall of the heating chamber 3111, and the atomizing matrix 400 is heated and atomized by circumferential heat exchange, and the heat exchange method includes airflow, thermal radiation or contact heat exchange. The heating element 370 can be formed by winding a plurality of heating wires, or it can be a heating element 370 with a sheet-like heating structure wound into a cylindrical shape, and can be heated by electromagnetic heating or by resistance heating. The specific heat exchange method and heat exchange material have been disclosed by multiple existing patent documents, and will not be described in detail here.

[0056] In order to ensure that the aerosol content and other aspects of the generating device are uniform and meet the requirements of users during use, the mounting bracket 310 includes a first end 313 and a second end 314 symmetrically arranged along its mounting axis, and the atomizing matrix 400 includes a matrix segment 430, which extends from the first end 313 into the heating chamber 3111, and a side of the matrix segment 430 close to the first end 313 is aligned with a side of the heating chamber 3111 close to the first end 313, and the movable member 320 and the driving member 330 are arranged at the second end.

[0057] It should be further explained that the mounting bracket 310 can adapt to the structural dimensions of the atomizing matrix 400, and is generally a straight tubular or strip-shaped structure, and the mounting axis is a line connecting the midpoints of the first end 313 and the second end 314, and is a straight line distributed in the direction from the first end 313 to the second end 314. Therefore, according to usage habits, the top of the matrix segment 430 of the atomizing matrix 400 is flush with the top of the heating chamber 3111 along the vertical direction. Of course, a certain installation error is allowed to exist, and the error does not exceed 2mm. Too large an error will affect the generation and content of aerosol.

[0058] In order to better trigger the movement of the driving member 330, a plurality of protrusions 333 are provided at one end of the driving member 330 away from the movable member 320. The protrusions 333 can drive the driving member 330 to reciprocate in a direction perpendicular to the installation axis. The protrusions 333 can protrude from the entire outer shell 100, providing the user with a fulcrum for operation.

[0059] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
