[0167] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0168] One embodiment of the present application provides an aerosol generating device for generating aerosol. In some embodiments, the aerosol generating device may include two or more parts that are separated or replaced from each other, which, when combined, form a complete combined use state of the aerosol generating device and can generate aerosol in response to user operations.

[0169] In some embodiments, the aerosol generating device can be selectively used in combination with at least two types of consumer products of different types to form an aerosol. For example, in some embodiments, the aerosol generating device can be selectively used with any one of the first type of consumer products or the second type of consumer products to form an aerosol generating device to generate an aerosol.

[0170] In some embodiments, the aerosol generating device is configured to simultaneously receive both the first type of consumer product or the second type of consumer product and heat them simultaneously to generate an aerosol.

[0171] In some embodiments, the aerosol generating device may comprise a controller capable of controlling the activation of heating of a first type of consumer product in a first power output mode and the activation of heating of a second type of consumer product in a second power output mode.

[0172] In some embodiments, the first type of consumer product may include a liquid matrix, and in use, at least one component of the liquid matrix vaporizes to generate an aerosol when heated. In some embodiments, the liquid matrix may include glycerin, propylene glycol, etc., which can be heated and vaporized to generate an aerosol.

[0173] In some embodiments, the second type of consumer product may include a solid aerosol-generating article, which is heated to form an aerosol for inhalation by volatilizing or releasing at least one component of the solid aerosol-generating article.

[0174] In some embodiments, the solid aerosol-generating product preferably uses a tobacco-containing material that releases volatile compounds from the matrix when heated; or it can also be a non-tobacco material that can be heated and suitable for electric heating and smoking. In some specific embodiments, the aerosol-generating product preferably uses a solid matrix, which can include one or more of powders, particles, fragments, strips, or flakes of one or more of vanilla leaves, dried flowers, volatile aroma herbal crops, tobacco leaves, homogenized tobacco, and expanded tobacco; or, the solid matrix can contain additional tobacco or non-tobacco volatile aroma compounds to be released when the matrix is ​​heated. And in some embodiments, the aerosol-generating product can be configured to be similar to a cigarette stick, or similar to a capsule, etc.

[0175] Figures 1 to 3 A schematic diagram of an aerosol generating device of a specific embodiment is shown, comprising several components disposed within an outer body or housing (which may be referred to as a shell). The overall design of the outer body or housing may vary, and the type or configuration of the outer body that may define the overall size and shape of the aerosol generating device may vary. Typically, the elongated body may be formed from a single integral shell, or the elongated shell may be formed from two or more separable bodies.

[0176] For example, the aerosol generating device may have a power supply mechanism 400 at one end having a housing containing one or more reusable components (e.g., a battery such as a rechargeable battery and / or a rechargeable supercapacitor, and various electronic devices for controlling the operation of the article).

[0177] Specifically Figures 1 to 3 A schematic diagram of an aerosol generating device according to an embodiment is shown, in which the aerosol generating device comprises:

[0178] The housing 10 basically defines the outer surface of the aerosol generating device, and has a proximal end 110 and a distal end 120 opposite to each other along the length direction; in use, the proximal end 110 is an end that is convenient for operating to accommodate the aerosol generating product 1000 and heat and inhale; the distal end 120 is an end away from the user.

[0179] In some examples, housing 10 may be formed of a metal or alloy such as stainless steel, aluminum, etc. Other suitable materials include various plastics (eg, polycarbonate), metal-plating over plastic, ceramics, and the like.

[0180] according to Figure 1 As shown, the housing 10 comprises:

[0181] The first shell 11 and the second shell 12 are arranged in sequence along the longitudinal direction; wherein the first shell 11 is close to and defines the proximal end 110, and the second shell 12 is close to and defines the distal end 120. In some embodiments, the first shell 11 surrounds and defines the space of the heating part; the second shell 12 surrounds and defines the internal space of the power supply mechanism 400. And in Figures 1 to 3 As shown, the first housing 11 can be removed or disassembled from the second housing 12, so that the internal heating mechanism 200 and the atomizer 300 are exposed or revealed after removal.

[0182] according to Figures 1 to 3 As shown, the first shell 11 of the housing 10 of the aerosol generating device defines a first opening 111 at the proximal end 110, and the user can removably accommodate the aerosol generating product 1000 in the aerosol generating device through the first opening 111. For example, when inhalation is required, the user accommodates the aerosol generating product 1000 in the aerosol generating device through the first opening 111, and operates the aerosol generating device to heat the aerosol generating product 1000 to generate aerosol for inhalation; when the inhalation is completed, the user removes the aerosol generating product 1000 from the aerosol generating device through the first opening 111. Specifically, the operation of receiving the aerosol generating product 1000 from the aerosol generating device or removing it from the first opening 111 is performed along the longitudinal direction of the aerosol generating device, for example Figure 2 As shown by the arrow P1.

[0183] according to Figures 1 to 3 As shown, the housing 10 of the aerosol generating device is provided with a movable shielding element 112 at the proximal end 110; the shielding element 112 can move relative to the housing 10 along the width direction, such as Figure 2As shown by the arrow P2 in the middle, the first opening 111 is opened or closed. When the aerosol generating product 1000 needs to be received in the aerosol generating device for heating, the user opens the first opening 111 by moving the shielding element 112, so that the user can receive the aerosol generating product 1000 through the first opening 111 in the heating mechanism 200 for heating. As shown in the figure, when the aerosol generating product 1000 is received in the aerosol generating device for heating, a part of the aerosol generating product 1000, such as the filter mouthpiece, is located or exposed outside the aerosol generating device, so as to facilitate the user to inhale.

[0184] according to Figures 3 to 6 As shown, after the first housing 11 is removed, the heating mechanism 200 and the atomizer 300 assembled in the first housing 11 are exposed, so that the user can detach or separate them from the power mechanism 400, respectively.

[0185] Through the above detachable connection method, the first shell 11 is connected to the power supply mechanism 400 or detached from the power supply mechanism 400 to form different connection states, wherein in the first connection state, the heating mechanism 200 and the atomizer 300 are surrounded and covered, and in the second connection state, the heating mechanism 200 and the atomizer 300 are opened, exposed or exposed.

[0186] Alternatively, in other variable implementations, the first housing 11 can also change the arrangement in the first connection state and the second connection state described above by moving in the longitudinal direction relative to the power supply mechanism 400. The first housing 11 is movably arranged so as to cover or reveal the heating mechanism 200 / atomizer 300 by moving.

[0187] At the same time, when the first shell 11 covers or surrounds or surrounds the heating mechanism 200 and the atomizer 300, the heating mechanism 200 and the atomizer 300 are blocked and cannot be disassembled or removed from the power mechanism 400 by the user; and when the first shell 11 exposes or reveals the heating mechanism 200 and the atomizer 300, the user can be allowed to disassemble or remove the heating mechanism 200 and the atomizer 300 from the power mechanism 400.

[0188] according to Figures 3 to 6 As shown, the aerosol generating device also includes:

[0189] The first side 130 and the second side 140 are opposite to each other in the width direction; the longitudinally extending heating mechanism 200 is arranged near the first side 130, and the atomizer 300 is arranged near the second side 140. And, when the first housing 11 is in a disassembled position or a moved position from the power mechanism 400, the exposed atomizer 300 can be removed or disassembled along the width direction of the aerosol generating device, thereby the second side 140.

[0190] Accordingly Figures 3 to 10 As shown, the power supply mechanism 400 is provided with:

[0191] The bracket 13 protrudes or extends from the power supply mechanism 400 toward the proximal end 110; after assembly, the bracket 13 is covered by the first housing 11. Specifically, the bracket 13 has a connecting structure 133 such as a convex protrusion for connecting with a slot on the first housing 11, so that the first housing 11 is stably connected to the bracket 13 and will not be loosened from the second housing 12.

[0192] In use, the bracket 13 is used to support or install the heating mechanism 200 and the atomizer 300. Figures 3 to 6 As shown, the bracket 13 is provided with a screw hole 132 at the upper end facing the proximal end 110 .

[0264] In some specific embodiments, the MCU controller on the first circuit board 122 controls the second circuit board 160 to provide power to the heating mechanism 200 to heat the aerosol generating article 1000 to generate the second aerosol according to the input signal of the input element 113. And specifically, for example, the applicant provides a variety of modes and content details about heating the aerosol generating article 1000 according to the heating curve of the predetermined time in Chinese patent application CN112335940A, etc., and the above documents are fully incorporated herein by reference.

[0265] In some specific embodiments, the MCU controller on the first circuit board 122 controls the third circuit board 170 to provide power to the atomizer 300 for heating in a constant power output mode according to the user's puffing action sensed by the airflow sensor 150. Specifically, for example, the applicant provides a constant power supply mode and content details for heating atomization in Chinese patent application CN115067564A, etc., and the above-mentioned documents are incorporated herein by reference in their entirety. Or in some other implementations, power output can also be provided in a constant temperature mode.

[0266] And in some embodiments, the MCU controller controls the supply of power to the heating mechanism 200 and the atomizer 300 to be performed independently and simultaneously, or the supply of power to the heating mechanism 200 and the atomizer 300 at the same time does not affect each other.

For example, in some specific embodiments, the storage amount of the liquid matrix in the liquid storage chamber 315 of the atomizer 300 is substantially equal to the amount of liquid matrix that the atomizer assembly needs to consume when the user heats 10 aerosol generating products 1000 through the heating mechanism 200 for inhalation. That is, the storage amount of the liquid matrix in the liquid storage chamber 315 for heating and atomization by the heating element 390 can be sufficient to match the user's inhalation of 10 aerosol generating products 1000; or it can be more, such as 15.
