These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. Or a known electronic atomization device that can generate an aerosol by heating a vaporized liquid and tobacco or other non-tobacco product separately and simultaneously; and the separately generated aerosols are mixed to form a mixed aerosol and then delivered to the user.

And in some embodiments, the aerosol-generating product can be configured to be similar to a cigarette stick, or similar to a capsule, etc.

Figures 1 to 3 show schematic diagrams of an aerosol generating device of a particular embodiment, 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.

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).

Specifically, Figures 1 to 3 show schematic diagrams of an aerosol generating device according to an embodiment. In this embodiment, the aerosol generating device includes:

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.

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

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

The first housing 11 and the second housing 12 are sequentially arranged in the longitudinal direction; wherein the first housing 11 is close to and defines the proximal end 110, and the second housing 12 is close to and defines the distal end 120. In some embodiments, the first housing 11 surrounds and defines the space of the heating part; the second housing 12 surrounds and defines the internal space of the power supply mechanism 400. And as shown in FIGS. 1 to 3, 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.

As shown in FIGS. 1 to 3 , 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 article 1000 in the aerosol generating device through the first opening 111. For example, when inhalation is required, the user accommodates the aerosol generating article 1000 in the aerosol generating device through the first opening 111, and operates the aerosol generating device to heat the aerosol generating article 1000 to generate aerosol for inhalation; when the inhalation is completed, the user removes the aerosol generating article 1000 from the aerosol generating device through the first opening 111. Specifically, the operation of receiving the aerosol generating article 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, such as shown by the arrow P1 in FIG. 2 .

As shown in FIGS. 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 element 112 can move relative to the housing 10 in the width direction, as shown by arrow P2 in FIG. 2 , so as to open or close the first opening 111. 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.

According to FIGS. 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 the user can detach or separate them from the power mechanism 400 , respectively.

Through the above detachable connection method, 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 in the first connection state In the middle, 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 or exposed or exposed.

The first housing 11 is movably arranged so as to cover or reveal the heating mechanism 200/atomizer 300 by moving.

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.
