[0002] The aerosol generating device is a type of product that utilizes the thermal effect of a heating body to heat the atomizing matrix disposed in its heating chamber so that the atomizing matrix generates an aerosol without burning. At present, there are many types of atomizing matrices on the market, and the sizes and structures of the atomizing matrices are different due to different models. For example, the two most popular models on the market are TEREA and NSCS. The length of NSCS is shorter than that of TEREA. For different types of atomizing matrices, the atomizing device needs to be set with corresponding structures and sizes. It is impossible to heat and atomize atomizing matrices of other sizes and shapes, resulting in users only being able to use the corresponding atomizing matrix after purchasing an atomizing device. As there are many types of atomizing matrices, users need to purchase corresponding atomizing devices when experiencing different atomizing matrices, which undoubtedly increases the user's usage cost and brings a bad user experience.

DETAILED DESCRIPTION

[0024] 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. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and 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 description in the specification and the general technical knowledge in the art.

[0025] 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.

[0026] 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).

[0027] 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.

[0028] refer to Figures 1 to 8 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] refer to Figures 1 to 3The 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.

[0033] refer to Figures 1 to 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 3 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 divides the accommodating space 311 into a heating chamber 3111 and an adjusting chamber 3112 along the direction of the mounting axis. A heating element 370 is provided on the inner wall of the heating chamber 3111, and the heating element 370 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 rotate around the mounting axis and drive the movable member 320 to reciprocate along 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] refer to Figure 6 and 7The driving member 330 includes a driving portion 331 and a transmission portion 332. The movable member 320 is movably mounted on one end of the transmission portion 332. The driving portion 331 is used to trigger the transmission portion 332 to rotate around the installation axis so that the movable member 320 moves linearly along the direction of the installation axis.

[0040] refer to Figure 6 and 7 The outer circumference of the transmission part 332 is provided with a thread 3321, and the movable part 320 is movably sleeved on the transmission part 332. The transmission part 332 can rotate around the installation axis to drive the movable part 320 to perform linear reciprocating motion along the installation axis. The mechanical transmission principle of the screw converting rotation into linear motion is used. The screw is used as the driving part 331 to convert the rotational motion of the driving part 331 into the linear motion of the movable part 320, thereby realizing the adjustment of the position of the movable part 320 and completing the adjustment of the extension length of the heating chamber 3111.

[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, the movable member 320 has a first heating position and a second heating position, and the driving member 330 has a first position and a second position. In the first state, the driving member 330 is located at the first position, the movable member 320 is located at the first heating position, and the heating element 370 is used to heat the first type of atomizing matrix (such as TEREA). In the second state, the driving member 330 is located at the second position, the movable member 320 is located at the second heating position, and the heating element 370 is used to heat the second type of atomizing matrix (such as NSCS).

[0043] refer to Figures 6 to 8The atomizer 300 further includes a detection circuit 350 and a detection switch 360. The detection switch 360 has a first detection position and a second detection position. When the driving part 331 triggers the transmission part 332 to rotate around the installation axis and drives the movable part 320 to move to the first heating position, the detection switch 360 is located in the first detection position. When the driving part 331 triggers the transmission part 332 to rotate around the installation axis and drives the movable part 320 to move to the second heating position, the detection switch 360 is located in the second detection position. The detection circuit 350 is used to detect the position of the detection switch 360 and output a circuit signal corresponding to the position of the detection switch 360 to trigger the working temperature corresponding to the circuit signal to heat the first type of atomization substrate or the second type of atomization substrate.

[0044] The detection circuit 360 is electrically connected to the control component 220. When the detection circuit 360 outputs a circuit signal corresponding to the first detection position, it can trigger the control component 220 to output an operating temperature (or combustion curve) corresponding to the operation of the first type of atomization matrix. When the detection circuit 360 outputs a circuit signal corresponding to the second detection position, it can trigger the control component 220 to output an operating temperature (or combustion curve) corresponding to the operation of the second type of atomization matrix.

[0045] It is defined that when the movable part 320 is located at the first heating position, the heating chamber 3111 has a first heating length S1, and when the movable part 320 is located at the second heating position, the heating chamber 3111 has a second heating length S2. 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 heating lengths correspond to the lengths of the matrix segments 430 of different types of atomization matrices 400.

[0046] In one embodiment, the value of S1 is greater than the value of S2, that is, when the movable part 320 is located at the first heating position, it can adapt to a larger atomized matrix 400 (such as TEREA), and when the movable part 320 is located at the second heating position, it can adapt to a smaller atomized matrix 400 (such as NSCS).

[0047] refer to Figure 6 and Figure 7 The driving part 331 is provided with a protrusion 3311 and a recess 3312 along a direction perpendicular to the installation axis. When the detection switch 360 is in the first detection position, at least part of the structure of the detection switch 360 is arranged in the recess 3312. When the detection switch 360 is in the second detection position, the protrusion 3311 squeezes the detection switch 360.

[0048] refer to Figure 8The detection switch 360 includes a movable portion 361, a movable groove 362 and an elastic portion (not shown in the figure). When the detection switch 360 is in the first detection position, the movable portion 361 extends out of the movable groove 362 and is arranged in the recessed portion 3312. When the detection switch 360 is in the second detection position, the protrusion 3311 squeezes the movable portion 361 so that the movable portion 361 retracts into the movable groove 362.

[0049] The elastic part is arranged between the movable part 361 and a part of the inner wall of the movable groove 362 . The elastic part has elastic restoring force when subjected to an applied force. The elastic part may be a spring or other elastic structure.

[0050] When the driving member 330 rotates and switches from the first position to the second position, the protrusion 3311 and the recessed portion 3312 also rotate synchronously. At this time, the protrusion 3311 rotates to a setting corresponding to the detection switch 360, and the protrusion 3311 squeezes the movable portion 361 back into the movable groove 362. The elastic portion is in a compressed state and has an elastic restoring force that allows the movable portion 361 to extend out of the movable groove 362. When the driving member 330 switches from the second position to the first position, the protrusion 3311 rotates to be offset from the detection switch 360, and the recessed portion 3312 rotates to a setting corresponding to the detection switch 360. Under the action of the elastic restoring force of the elastic portion, the movable portion 361 extends out of the movable groove 362 and is set in the recessed portion 3312.

[0051] It should be further explained that the above-mentioned movable part 361 can be retracted into the movable groove 362, which can be either a complete retraction or a partial retraction. At this time, the squeezing force of the protrusion 3311 and the elastic restoring force of the elastic part reach a balance, so that the movable part 361 is stable, thereby stabilizing the final output circuit signal.

[0052] In one embodiment, the recessed portion 3312 has an arcuate surface, which can provide a movement trajectory for the movable portion 361, so that the movable portion 361 can smoothly enter the recessed portion 3312 from the raised portion 3311, or move from the recessed portion 3312 to the raised portion 3311 and be squeezed.

[0053] refer to Figure 4 and 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 along the direction of the mounting axis. A movable slider 321 is provided on the side of the movable part 320. The movable slider 321 is movably arranged on the movable track 312.

[0054] In one embodiment, the heating element 370 is a cylindrical structure extending in the direction of the installation axis, which is used to heat the atomized matrix 400. The heating element 370 can be arranged in contact with the inner wall of the heating chamber 3111, and the atomized 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 in which a sheet-like heating structure is wound into a cylindrical shape, and electromagnetic heating can be used, or resistance heating can be used. The specific heat exchange method and heat exchange material have been disclosed in multiple existing patent documents, and will not be repeated here.

[0055] 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.

[0056] 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.

[0057] In one embodiment, the atomizer 300 further includes a mounting base 340, which is disposed at the second end 314 of the mounting bracket 310, and a portion of the structure of a driving portion 331 of the driving member 330 is disposed on the mounting base 340. In order to facilitate determination of whether the driving member 330 has been rotated into place, the mounting base 340 may further be provided with marks, such as marking positions corresponding to 0°, 90°, 180°, and 360° along the circumference of the driving portion 331. An arrow is disposed on the driving portion 331. In the initial position (such as the first position), the arrow points to 0°. When the generating device adapts to two types of atomization matrices 400, the switching from the first position to the second position is completed by rotating the driving portion 331 until the arrow points to 180°.

[0058] 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.
