Referring to fig. 3, 6, 8-11, in one embodiment provided herein, an air intake 40 is provided at the bottom end of the housing assembly 10, i.e., on the end cap 12. A portion of the area of the first cavity 121 of the end cap 12 forms an air guide cavity 122, and the air flow enters the air guide cavity 122 through the air inlet 40. One end of the first air inlet hole 322 on the second sealing plug 32 is communicated with the air guide cavity 122, the other end of the first air inlet hole 322 is communicated with the inner cavity of the bracket 22, the external air flow enters the atomizing cavity 25 of the atomizing core unit 20 through the air inlet 40 and the air guide cavity 122, the aerosol formed in the atomizing cavity 25 sequentially enters the first air outlet hole 311 on the first sealing plug 32 through the inner cavity of the sleeve 23, and the second air outlet hole 331 on the first liquid absorbing element 33 finally enters the nozzle opening 130 to be absorbed by the user.

In order to prevent condensate from overflowing from the air inlet 40, a second liquid absorbing member 41 is provided inside the air guide chamber 122, and the second liquid absorbing member 41 is preferably made of a material such as cellucotton, sponge, or the like having a capillary structure. The second wicking element 41 can fill most of the air conducting chamber 122 while vent holes 411 are provided in the second wicking element 41 to prevent air flow from affecting the interior of the aerosolizing chamber 25. This air vent 411 staggers along the vertical projection plane of perpendicular to casing and the open end of support 22 along the vertical projection plane of casing 11 at least partially to under the prerequisite of guaranteeing that outside air current can smoothly get into atomizing chamber 25, thereby avoid the condensate that produces in atomizing chamber 25 directly to get into air vent 411 through the open end of support 22 and absorbed by second imbibition element 41, further, air inlet 40 is along the vertical projection and the air vent 411 on second imbibition element 41 of being staggered, avoid the condensate directly to overflow to air inlet 40 through air vent 411. It will be appreciated that condensate flowing through the open end of the holder 22 will be absorbed directly by the second wicking element 41. Meanwhile, the airflow sensing switch assembly 43 is arranged at the right side of the second liquid suction element 41, the air inlet end of the air inlet column on the sealing sleeve 432 is completely staggered with the atomizing chamber 25, the second liquid suction element 41 is arranged in the middle, and condensate is difficult to flow into the airflow sensing switch 431 through the air inlet column of the sealing sleeve 432.

Since the air inflow of the air inlet 40 may directly affect the suction resistance of the aerosol-generating device, in an embodiment provided in the present application, the air adjustment assembly 60 is disposed at the air inlet 40, the air adjustment assembly 60 can block at least a portion of the air inlet 40, and the air adjustment assembly can move relative to the end cover 12, so as to adjust the air inlet cross-sectional area of the air flow passage allowed by the air inlet 40, and therefore when the air adjustment assembly 60 is located at different positions, the air inflow at the air inlet 40 is different. Meanwhile, in order to avoid the operational interference of the circulation adjustment mode to the user, in one example provided in the present application, the aerosol-generating device is configured to have only a two-stage air adjustment mode, which corresponds to a one-stage air adjustment mode when the air adjustment assembly 60 is in the first position, as shown with reference to fig. 9; when the air regulating assembly 60 is in the second position, corresponding to the two-stage air regulating mode, referring to fig. 8, the user does not consider the correspondence between other positions of the air regulating assembly 60 and the intake air amount. For convenience of description, in the embodiment of the present application, the primary air conditioning mode is corresponding to a small air intake amount mode, and the corresponding aerosol has a larger suction resistance; the secondary air regulation mode is corresponding to a large air inflow mode, and the corresponding aerosol has small suction resistance. Further, the air inlet 40 includes a first air inlet 401 and a second air inlet 402, when the air regulating assembly is in the first position, the first air inlet 401 is in a fully open state, and the second air inlet 402 is in a closed state; when the air adjustment assembly 60 is in the second position, the second air inlet 402 is in a fully open state and the first air inlet 401 is in a closed state. The air inlet cross-sectional areas of the first air inlet 401 and the second air inlet 402 are different, in one example, the first air inlet 401 includes one air inlet hole, and the second air inlet 402 includes two air inlet holes, wherein the air inlet cross-sectional areas of the two air inlet holes of the second air inlet can be the same or different, but the sum of the air inlet cross-sectional areas of the two air inlet holes is larger than the air inlet cross-sectional area of the air inlet hole of the first air inlet. It will be appreciated that the air inlets 40 and corresponding air regulating assemblies 60 described above may be arranged in a plurality of groups, for example two, three or four groups, etc., in order to further enhance the air regulating capabilities of the aerosol-generating device. Any one group of the air adjusting components can realize two-stage air adjusting functions, and different suction resistance can be realized by adjusting the positions of the air adjusting components of some groups. For some aerosol-generating devices with adjustable heating power, several air intake modes need to be set in order to match different heating powers with different suction resistances, thereby improving the amount of smoke. Aerosol generating devices with a single heating mode, such as disposable aerosol generating devices, generally have only one heating power, so that a simple two-stage airflow mode is only required to be configured, and a one-stage air inlet mode can be selected for users who prefer large suction resistance; for users who prefer a small suction resistance, the two-stage intake mode may be selected.

The specific air adjustment mode of the air adjustment assembly 60 can be set to be rotating or sliding. For a cylindrical aerosol-generating device, provision for rotational air-conditioning is preferred. For non-cylindrical aerosol-generating devices, such as box-shaped or flat aerosol-generating devices, the rotary air adjustment assembly is inconvenient to install and therefore needs to be provided as a sliding air adjustment assembly. The specific structure and operation of the air conditioning assembly 60 will now be described, taking a box-shaped aerosol generating device as an example. The air regulating assembly 60 mainly comprises a sliding member 61, at least part of the sliding member 61 is exposed out of the outer surface of the aerosol generating device, and the position of the sliding member is changed by applying force to the exposed part of the sliding member. In order to avoid the exposed portion of the slider 61 from detracting from the aesthetics of the major face of the housing of the aerosol-generating device, in a preferred embodiment the air regulating assembly 60 is mounted on the end cap, and the end face of the air regulating assembly 60 is no higher than the end face of the end cap. A groove is provided in the end cap 12 and a slider 61 is mounted in the groove of the end cap 12. Further, a sliding groove 123 is formed in a part of the bottom wall of the groove, the sliding groove 123 is open, the two sides of the sliding part are provided with the clamping pieces 62, and the clamping pieces 62 are clamped on the end faces of the two sides of the sliding groove 123. The length over which the slider 61 can move is the length of the chute 123. The two end walls of the sliding slot 123 stop the slider 61 from sliding further by limiting the two catches 62 on the slider 61. When the sliding member 61 abuts against one end of the sliding slot 123, the air adjustment assembly 60 is in the first position, and the first air inlet 401 is fully opened, and the second air inlet 402 is blocked by the sliding member. When the sliding member 61 abuts against the other end of the sliding slot 123, the air adjustment assembly 60 is in the second position, and the first air inlet 401 is completely blocked by the sliding member, and the second air inlet 402 is completely opened.

Referring to fig. 10, in order to facilitate the application of force by the user, the outer surface of the sliding member 61 is provided with anti-slip lines, which are provided as a plurality of convex structures. In order to enhance the touch feeling of the user during the movement of the slider, a flexible element 63 is disposed between the slider 61 and the end cap 12, the flexible element 63 is preferably made of silicone material, the user can apply enough pushing force to the slider 61, and the flexible element 63 has enough deformation space, so that the slider 61 can be pressed by enough force without generating reaction force to the user, and the touch feeling of the air adjustment assembly 60 is improved.

In order to further improve the use experience of the aerosol generating device, the second liquid absorption element 41 is arranged close to the air inlet 40, and the second liquid absorption element 41 is a porous element and has a loose porous structure, so that sound waves reaching the second liquid absorption element can be buffered and absorbed, the sound waves of noise generated by air flow can not be reflected out after the air flow passes through the plane of the second liquid absorption element, and therefore a user can not hear the noise generated by the air flow in time under the air inlet mode using large air inflow.

In one embodiment provided by the present application, since the air regulating assembly 60 is disposed at the bottom end face of the aerosol generating device, and the top end face of the slider of the air regulating assembly 60 does not exceed the bottom end face of the end cap, the air regulating assembly does not affect the overall aesthetic appearance of the aerosol generating device. Although the air regulating assembly is arranged at a relatively hidden position, the air regulating assembly 60 is only provided with a two-stage airflow mode, namely when the air regulating assembly 60 is at the first position, which is equivalent to the leftmost side of the stroke of the sliding member 61, the aerosol generating device is in a one-stage airflow mode, and the suction resistance is large; when the air adjustment assembly 60 is moved to the second position, corresponding to the rightmost side formed by the slider 61, the aerosol-generating device is in the secondary airflow mode with less resistance to draw. In the whole air adjusting process, a user does not need to observe or think, the operation is simple and convenient, and even if the primary user uses the air adjusting device for the first time, the operation mode of the air adjusting assembly 60 can be rapidly mastered. It will be appreciated that the air regulating assembly 60 may be disposed at other positions of the housing assembly, and the air input amount of each stage of the airflow pattern may be optimally set according to the internal structure of the aerosol generating device, which is not limited herein.

It should be noted that the description and drawings of the present application illustrate preferred embodiments of the present application, but are not limited to the embodiments described in the present application, and further, those skilled in the art can make modifications or changes according to the above description, and all such modifications and changes should fall within the scope of the claims appended to the present application.
