In other words, the aerosol-generating device 100 according to the embodiment of the present application mainly comprises a body 10 having a liquid storage chamber and a receiving chamber, an atomizing assembly 20 disposed in the receiving chamber, a lower cap 30 disposed on the body 10, and a sealing sleeve 40 detachably connected to the body 10. Wherein, the body 10 has a liquid storage cavity and a containing cavity, and the liquid storage cavity and the containing cavity can be distributed in the body 10 at intervals. A liquid substrate may be stored in the reservoir chamber and the atomizing assembly 20 may be mounted in the receiving chamber.

The atomizing assembly 20 can include a heat generating body that generates heat when energized to convert a portion of the liquid substrate into aerosol form. The heating element may be a heating wire, a heating sheet, a heating coating, etc., and is not limited herein.

And atomization component 20 still is equipped with the air current passageway, and the air current passageway can communicate stock solution chamber and hold the chamber. The liquid substrate in the liquid storage cavity can be guided to the position of the heating element in the atomizing assembly 20, so that aerosol can be generated, and the converted aerosol can be sent out through the airflow channel.

It should be noted that the lower cover 30 can be matched with the body 10, and the accommodating cavity of the body 10 can be closed by the lower cover 30, so that the atomizing assembly 20 can be fixed in the accommodating cavity.

In addition, a first air port 31 is provided on the lower cover 30, and the first air port 31 can be respectively communicated with the air flow channel and the external environment. That is, the airflow from the external environment may enter the airflow channel via the first air port 31 and enter the atomizing assembly 20.

Since the first air ports 31 are respectively communicated with the air flow passage and the external environment, the liquid substrate may flow out from the first air ports 31 to the external environment, or dust in the external environment may flow into the interior of the aerosol generating device 100 through the first air ports 31. The present application specifically detachably connects the sealing sleeve 40 with the body 10 by mating the body 10 and the sealing sleeve 40. When the sealing sleeve 40 is connected to the body 10, the first air port 31 can be closed by the sealing portion 41 of the sealing sleeve 40.

The sealing portion 41 is not limited to a plug fitting to the first air port 31, and the sealing portion 41 may be a plug or the like, but is not limited thereto. The shape of the first air port 31 is not limited herein. Moreover, the connection relationship between the sealing sleeve 40 and the first air port 31 includes but is not limited to sleeving, and may also be a connection manner such as clamping, screwing and the like.

When the sealing sleeve 41 is sleeved on the body 10, the sealing sleeve 41 can be movable between a first preset position and a second preset position. When the sealing sleeve 41 is located at the first predetermined position, the sealing portion 41 may be connected to the first air port 31, and the first air port 31 is sealed by the sealing portion 41 and isolated from the external environment. When the sealing sleeve 41 moves outward to the second preset position, the sealing sleeve 41 is separated from the body 10, and at this time, the first air port 31 is communicated with the external environment.

And under the condition that the sealing sleeve 41 is of a cavity structure with an open end, and the length of the sealing part 41 is limited, and the sealing sleeve 41 is located between the first preset position and the second preset position, the body 10 can penetrate through the open end to be located in the cavity, the lower cover 30 is also located in the cavity, the sealing part 41 is separated from the first air port 31, and at the moment, the first air port 31 is communicated with the cavity and can still be kept in an isolated state with the external environment.

It should be noted that the number of the first air ports 31 in the aerosol-generating device 100 of the present application is one or more. When the size of the lower cover 30 is limited, the number of the first air ports 31 may be set to one. By setting the number of the first ports 31 to one, quick assembly of the seal portion 41 and the first ports 31 can be facilitated. And when the size of the lower cover 30 is sufficient, the number of the first air ports 31 may be set to be plural.

Therefore, according to the aerosol-generating device 100 of the embodiment of the present application, the first air port 31 of the lower cap 30 is engaged with the sealing portion 41 of the sealing sleeve 40, so that the sealing effect of the aerosol-generating device 100 can be achieved, the liquid substrate can be prevented from flowing out through the first air port 31, the dust can be prevented from accumulating in the first air port 31, and the safety of the user during use can be ensured.

According to an embodiment of the present application, as shown in fig. 2 to 4, the first port 31 is a hole which is recessed inward along an end surface of the first end of the lower cover 30, and the first end of the sealing portion 41 can be inserted to the first port 31 through the first end of the first port 31. For example, when the lower cover 30 extends in the up-down direction, the end surface of the first end of the lower cover 30 may be the lower end surface thereof, and the recessed direction of the first air vent 31 may be upward along the thickness direction of the lower cover 30. By providing the first air port 31 as an inwardly recessed hole, it is possible to facilitate the rapid insertion of the sealing portion 41 into the first air port 31 from the open portion of the first air port 31, which is advantageous to improve the assembly efficiency between the body 20 and the sealing sleeve 40.

Here, the number of the first air ports 31 may correspond to the number of the sealing portions 41, for example, when the number of the first air ports 31 is one, the number of the sealing portions 41 may also be one. For the case of providing two or more first air ports 31, when one first air port 31 is provided, the sealing portion 41 can be aligned quickly, so that quick and accurate positioning can be realized without adjusting the direction and position of the body 10 all the time. After positioning, the sealing portion 41 may be quickly inserted into the first air port 31.

Note that, by providing the first air port 31 as a hole recessed inward along the end surface of the first end of the lower cover 30, automated assembly is facilitated. Specifically, when the assembly is performed by using an automated device, the first air port 31 and the sealing portion 41 may be first positioned by the automated device. After the positioning is completed, the relative movement between the sealing sleeve 40 and the body 10 is driven by an automated device until the sealing portion 41 is inserted into the first air port 31. If the first air port 31 is provided by adopting a protruding structure on the lower cover 30, not only the positioning difficulty between the first air port 31 and the sealing portion 41 is increased, but also it is not easy to insert the sealing portion 41 into the first air port 31 quickly, and the space required for the whole structure is also increased.

That is, by setting the first air port 31 as an inwardly recessed duct along the end surface of the first end of the lower cover 30, not only is the rapid insertion of the sealing portion 41 facilitated, but also the inwardly recessed design can greatly save space, so that the overall structure is more attractive and compact.

In some embodiments of the present application, as shown in fig. 2 to 4, the sealing part 41 is a columnar protrusion corresponding to the shape of the first air vent 31. For example, when the first gas port 31 is a cylindrical passage, the sealing portion 41 may be a cylindrical structure having the same shape as the first gas port 31. Through setting up sealing 41 to the structure corresponding with first gas port 31 shape, have simple structure, the production and processing of the sealing 41 of being convenient for has improved the assembly efficiency of sealing 41 and first gas port 31, has guaranteed the sealed effect of sealing 41 to first gas port 31.

Moreover, when the sealing portion 41 is a cylindrical protrusion corresponding to the shape of the first air port 31, the outer diameter of the sealing portion 41 may be larger than the inner diameter of the first air port 31, so as to achieve a better interference fit between the sealing portion 41 and the first air port 31, and further improve the sealing effect of the sealing portion 41 on the first air port 31. It should be noted that the cross section of the first air port 31 may be a continuous closed shape such as a polygon, a perfect circle, or an ellipse. And the shape of the cross section of the sealing portion 41 corresponds to the shape of the first air port 31, that is, when the cross section of the first air port 31 is polygonal, the cross section of the sealing portion 41 is also polygonal; when the cross section of the first air port 31 is a perfect circle, the cross section of the seal portion 41 is also a perfect circle; when the cross section of the first air port 31 is elliptical, the cross section of the seal portion 41 is also elliptical. That is, the shapes of the first air port 31 and the sealing portion 41 need to be matched, so that the sealing effect between the first air port 31 and the sealing portion 41 can be improved, and the matching between the first air port 31 and the sealing portion 41 can be realized.

According to an embodiment of the present application, as shown in fig. 2 to 4, the axial length of the sealing portion 41 is smaller than the axial length of the first port 31. Because the axial length of the sealing portion 41 is smaller than the axial length of the first air port 31, after the first end of the sealing portion 41 passes through the first end of the first air port 31 and is inserted into the first air port 31, a gap is formed between the first end of the sealing portion 41 and the plane where the second end of the first air port 31 is located, and the sealing portion 41 can be prevented from pressing and damaging structures near the second end of the first air port 31. It should be noted that the first end of the sealing portion 41 and the second end of the sealing portion 41 are respectively located in the axial direction of the sealing portion 41, and the first end of the first air port 31 and the second end of the first air port 31 are respectively located in the axial direction of the first air port 31.

Further, if the axial length of the seal portion 41 is set to be larger than the axial length of the first air port 31, the risk of tearing the seal portion 41 by pulling is also exacerbated.

Moreover, the axial length of the sealing portion 41 is set to be smaller than the axial length of the first air port 31, and when the sealing portion 41 is completely located in the first air port 31, the bottom wall of the sealing sleeve 40 can be stopped against the end surface of the first end of the lower cover 30, so as to further prevent the liquid medium from flowing out of the first air port 31 or prevent external dust from entering the first air port 31.

In some embodiments of the present application, the first gas port 31 and the sealing portion 41 are interference fit, as shown in fig. 3. That is, the outer diameter of the sealing portion 41 may be greater than the inner diameter of the first gas port 31, with the tolerance band of the first gas port 31 being below the tolerance band of the sealing portion 41. Through first gas port 31 and 41 interference fit of sealing to can guarantee that first gas port 31 and 41 complex are inseparabler, not only can prevent effectively that sealing 41 from droing from first gas port 31, can also reach and realize the better sealed effect.

In some embodiments of the present application, the first air port 31 has a polygonal cross-section with a transition section between two adjacent sides of the polygon.

That is, the first gas port 31 may be a polygonal pillar-shaped duct. The polygon can be a closed plane figure formed by sequentially connecting three or more line segments end to end. The planar pattern may be a regular polygon or a non-regular polygon, a convex polygon or a concave polygon, and the specific form of the planar pattern is not limited herein. For example, the cross section of the first air port 31 may be a regular hexagon, and the regular hexagon may be a convex hexagon. It should be noted that the direction of the cross section of the first air port 31 may be perpendicular to the axis of the first air port 31. For example, when the first air port 31 extends in a vertical direction, the cross section of the first air port 31 may extend in a horizontal direction.

Wherein, still be equipped with the transition face between two adjacent side of polygon prism, avoid sealing 41 to peg graft in the first gas port 31 in, produce great clearance between the interior wall face of the lateral surface on the sealing 41 and first gas port 31 to influence the sealed effect of sealing 41 to first gas port 31. Further, by providing the transition surface, the contact area between the inner wall surface of the first air port 31 and the seal portion 41 can be increased, and the frictional force between the first air port 31 and the seal portion 41 can be increased. The inner wall surface of the first air port 31 is an inner wall surface of the lower cover 30 corresponding to the position of the first air port 31.

In the present embodiment, by designing the first gas port 31 as a polygonal column-shaped duct, it is possible to prevent the frictional force between the sealing portion 41 and the inner wall surface of the first gas port 31 from being excessively small, resulting in the sealing portion 41 being easily detached from the first gas port 31.

In addition, two adjacent sides of the polygon may be straight sides or arc sides, and are not limited herein.

According to one embodiment of the application, the transition section is an arc-shaped section. That is, two adjacent sides of the cross section of the first air port 31 are connected by an arc-shaped section. By providing the transition section as an arc-shaped section, the transition between two adjacent sides of the cross section of the first air port 31 can be made more natural. And when the opening of segmental arc was towards the axis direction of first gas port 31, namely the segmental arc was crooked towards the axis direction of first gas port 31, can increase the area of the cross section of first gas port 31, thereby not only can make sealing 41 more easily fix a position with first gas port 31, be favorable to pegging graft sealing 41 to first gas port 31 in, and can also enlarge the speed of the fluid that flows in from first gas port 31, can also realize making user's experience comparatively comfortable suction resistance through the area that increases the cross section of first gas port 31 when first gas port 31 is as the air inlet. Moreover, the arc-shaped transition section can make the lines of the inner wall surface of the first air port 31 softer, and can effectively prevent the edges and corners of the inner wall surface of the first air port 31 from damaging the structural integrity of the sealing part 41 in the penetrating process of the sealing part 41. Further, the gap between the inner wall surface of the first port 31 and the outer wall surface of the seal portion 41 can be reduced by using the arc-shaped transition section, thereby improving the sealing effect of the seal portion 41 with respect to the first port 31.

Under the condition that the cross section of the first air port 31 is polygonal, and a transition section is arranged between two adjacent sides of the polygon, and under the condition that the transition section is an arc-shaped section, the outer diameter of the sealing part 41 can be larger than the inner diameter of the first air port 31, so that a good interference fit between the sealing part 41 and the first air port 31 is realized, and the sealing effect of the sealing part 41 on the first air port 31 is further improved.

According to an embodiment of the present application, as shown in fig. 5, the first port 31 is a circular hole, the first port 31 has a predetermined radial dimension, and a maximum radial dimension of at least a portion of the first end of the sealing portion 41 is greater than the predetermined radial dimension. In other words, the cross-section of the first gas port 31 may be circular, and the maximum radial dimension of at least a portion of the first end of the sealing portion 41 is greater than the radial dimension of the first gas port 31. By designing the maximum radial dimension of at least a part of the first end of the sealing portion 41 to be larger than the preset radial dimension, it is ensured that the interference fit between the sealing portion 41 and the inner wall surface of the first air port 31 can be better achieved, the sealing portion 41 can sufficiently fill the first air port 31, the liquid substrate is prevented from flowing out through the first air port 31, and dust is prevented from accumulating at the first air port 31. The circular hole may have a closed curve shape such as a perfect circle or an ellipse, and is not limited herein.

According to an embodiment of the application, the difference between the maximum radial dimension and the preset radial dimension ranges between 0.03mm and 0.08mm, inclusive. For example, the difference between the maximum radial dimension and the preset radial dimension may be 0.03mm, 0.05mm, or 0.08 mm.

In some embodiments of the present application, the first gas ports 31 have a diameter of 1.5mm to 3mm, inclusive. As shown in fig. 7, the L mark in the figure indicates the diameter. For example, the diameter of the first air port 31 may be 1.5mm, 2mm, 2.5mm, 3mm, etc., wherein the diameter of the first air port 31 may be selected according to the size of the lower cover 30. The larger the diameter of the first air port 31 is, the more convenient the positioning of the first air port and the sealing part 41 and the insertion of the first air port and the sealing part 41 are.

According to one embodiment of the present application, the depth of the first port 31 is between 1mm and 3mm, inclusive. As shown in fig. 7, the H mark in the figure indicates the depth. For example, the depth of the first air port 31 may be 1mm, 2mm, or 3mm, and the depth of the first air port 31 may be selected according to actual circumstances.

In some embodiments of the present application, the diameter of the first air port 31 is 1.5mm to 3mm, and the depth of the first air port 31 is 1mm to 3mm, which is advantageous for the automation of product assembly and provides a good structural strength for the sealing portion 41 of the sealing sleeve 40.

According to one embodiment of the application, at least a part of the outer side of the sealing portion 41 is provided with ribs. That is, beads may be provided on a certain position of the outer surface of the seal portion 41 or on the entire outer surface. When the bead portion is provided on a part of the outer surface of the seal portion 41, not only the sealing effect of the seal portion 41 with respect to the first air port 31 can be achieved, but also the assembly between the seal portion 41 and the first air port 31 can be facilitated. When the bead portions are provided at all positions of the outer surface of the seal portion 41, the sealing effect of the seal portion 41 with respect to the first air port 31 can be further improved, and the seal portion 41 and the lower cover 30 can be more firmly attached to each other.

In some embodiments of the present application, the bead extends in the circumferential direction of the seal portion 41. For example, the rib may be an annular protrusion and may be disposed on the outer periphery of the sealing portion 41, so that the sealing portion 41 can achieve a better sealing effect in the circumferential direction.

According to an embodiment of the present application, the sealing portion 41 is a soft material, has a characteristic of being easily deformed after being pressed, is easily inserted into the first air port 31, and can be rebounded after being inserted into the first air port 31, so that a contact area between the sealing portion 41 and an inner wall surface of the first air port 31 is further increased, and a sealing effect is improved.

According to one embodiment of the present application, the sealing sleeve 40 is an integrally formed piece. When the first air port 31 is packaged, it is not necessary to first pass a long plugging feature through the first air port 31, and then cut off the redundant part on the plugging feature and then install the limiting member on the body 10 to limit the plugging feature. The risk that the plugging feature piece is pulled and torn is high, redundant overlong parts need to be removed, and the defects that the production cost is increased, the operation method is complex, the assembly difficulty is high and the like are overcome. This application promotes the equipment convenience through improving the structural feature of seal cover 40 to make things convenient for aerosol to produce 100 products and accomplish automatic assembling process, realize mass production and reduce manufacturing cost.
