Detailed Description

In order to facilitate an understanding of the present application, the present application will be described in more detail below with reference to the accompanying drawings and detailed description.

In some embodiments, the aerosol-generating device may comprise two or more parts that are separate or replaceable from each other, which when combined form a complete combined use state of the aerosol-generating device and are operable by a respective user to generate an aerosol.

In some embodiments, the aerosol-generating device may be selectively used in conjunction 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 configured to cooperate with either of the first type of consumer product or the second type of consumer product selectively to produce an aerosol.

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

In some embodiments, the aerosol-generating device may comprise a controller capable of controlling the initiation of heating of a first type of consumer product in accordance with a first power output mode and capable of controlling the initiation of heating of either a second type of consumer product in accordance with a second power output mode.

In some embodiments, the first type of consumer product may comprise a liquid matrix which, in use, vaporises at least one component to produce an aerosol when heated. In some embodiments, the liquid matrix may include glycerin, propylene glycol, or the like, which can be heated to vaporize to generate an aerosol.

In some embodiments, the second type of consumer product may comprise a solid aerosol-generating article that is formed into an aerosol for inhalation by heating the solid aerosol-generating article, volatilizing or releasing at least one component of the solid aerosol-generating article.

In some embodiments, the solid aerosol-generating article preferably employs a tobacco-containing material that releases volatile compounds from a matrix upon heating; or may be a non-tobacco material capable of being heated and thereafter adapted for electrical heating for smoking. In some specific embodiments, the aerosol-generating article preferably employs a solid substrate, which may comprise one or more of a powder, granules, shredded strips, ribbons or flakes of one or more of vanilla leaves, dried flowers, volatilizable flavored herbal crops, tobacco leaves, reconstituted tobacco, expanded tobacco; alternatively, the solid substrate may contain additional volatile flavour compounds, either tobacco or non-tobacco, to be released when the substrate is heated. And in some embodiments, the aerosol-generating article may be configured to be a shape resembling a cigarette, or resembling the shape of a capsule, etc.

Fig. 1 to 3 show schematic views of an aerosol-generating device of a particular embodiment, comprising several components arranged within an outer body or housing (which may be referred to as a housing). The overall design of the outer body or housing may vary, and the pattern or configuration of the outer body, which may define the overall size and shape of the aerosol-generating device, may vary. Generally, the elongate body may be formed from a single unitary housing, or the elongate housing may be formed from two or more separable bodies.

For example, the aerosol-generating device may have a power supply mechanism 400 at one end, the power supply mechanism 400 being provided with a housing containing one or more reusable components (e.g., a secondary battery such as a rechargeable battery and/or a rechargeable supercapacitor, and various electronics for controlling the operation of the article).

Fig. 1 to 3 in particular show schematic views of an aerosol-generating device of an embodiment in which the aerosol-generating device comprises:

a housing 10 substantially defining an outer surface of the aerosol-generating device, having longitudinally opposed proximal and distal ends 110, 120; in use, the proximal end 110 is an end that facilitates the handling of the aerosol-generating article 1000 and heating and drawing; distal end 120 is the end remote from the user.

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

As shown in fig. 1, the housing 10 includes:

a first housing 11 and a second housing 12 arranged in order in the longitudinal direction; wherein the first housing 11 is adjacent to and defines a proximal end 110 and the second housing 12 is adjacent to and defines a distal end 120. In some embodiments, the first housing 11 encloses and defines a space inside the heating portion; the second housing 12 surrounds and defines an inner space of the power supply mechanism 400. And as shown in fig. 1-3, the first housing 11 is removable or detachable from the second housing 12 so that the internal heating mechanism 200 and atomizer 300 are exposed or revealed upon removal.

As shown in fig. 1-3, the first housing 11 of the housing 10 of the aerosol-generating device defines a first opening 111 at the proximal end 110 through which first opening 111 a user can removably receive an aerosol-generating article 1000 within the aerosol-generating device. For example, when inhalation is required, a user receives the aerosol-generating article 1000 through the first opening 111 into the aerosol-generating device and operates the aerosol-generating device to heat the aerosol-generating article 1000 to generate an aerosol for inhalation; when the suction is completed, the user removes the aerosol-generating article 1000 from the aerosol-generating device from the first opening 111. In particular, the operation of receiving or removing the aerosol-generating article 1000 from the first opening 111 in the aerosol-generating device is performed in a longitudinal direction of the aerosol-generating device, for example as indicated by arrow P1 in fig. 2.

As shown in fig. 1 to 3, the housing 10 of the aerosol-generating device is provided with a movable shielding element 112 at the proximal end 110; the shielding member 112 is movable in the width direction with respect to the housing 10 as indicated by an arrow P2 in fig. 2, thereby opening or closing the first opening 111. When it is desired to receive the aerosol-generating article 1000 in the aerosol-generating device for heating, the user opens the first opening 111 by moving the shielding element 112, thereby enabling the user to receive the aerosol-generating article 1000 in the heating mechanism 200 through the first opening 111 for heating. According to the figures, when the aerosol-generating article 1000 is received within an aerosol-generating device for heating, a portion of the aerosol-generating article 1000, such as a filter mouthpiece, is located or exposed to the outside of the aerosol-generating device for facilitating the user's inhalation.

As shown in fig. 3 to 6, 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 a user can detach or separate them from the power supply mechanism 400, respectively.

By the above detachable connection, the first housing 11 is connected to the power supply mechanism 400 or detached from the power supply mechanism 400 to form different connection states, wherein the heating mechanism 200 and the atomizer 300 are enclosed and surrounded or covered in the first connection state, and the heating mechanism 200 and the atomizer 300 are opened or exposed in the second connection state.

Or in other alternative implementations, the first housing 11 may also change the arrangement of 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 uncover the heating mechanism 200/atomizer 300 by movement.

Meanwhile, when the first housing 11 covers or encloses or surrounds the heating mechanism 200 and the atomizer 300, the heating mechanism 200 and the atomizer 300 are shielded from being detached or removed from the power supply mechanism 400 by user operation; and when the first housing 11 exposes or reveals the heating mechanism 200 and the atomizer 300, the user can be allowed to operate to detach or remove the heating mechanism 200 and the atomizer 300 from the power supply mechanism 400.
