The atomizing carrier 10 is used for attaching an atomized liquid such as an atomized liquid, and the heating element 20 heats under the action of an external power supply to atomize the atomized liquid attached to the surface of the atomizing carrier 10.

The atomizing carrier 10 has a first end face 10a, a second end face 10b provided opposite to the first end face 10a, and peripheral side faces, and groove structures 10c penetrating the first end face 10a and the second end face 10b are formed on the opposite peripheral side faces to be recessed inward, the groove structures 10c being for passing atomizing gas. The atomizing carrier 10 is mounted in a ventilation structure of the aerosol generating device, and in general, the atomizing carrier 10 has a cubic structure, and in a use state, the first end face 10a and the second end face 10b of the atomizing carrier 10 are end faces perpendicular to a flow direction of the atomizing gas, and the peripheral side faces are side faces parallel to the flow direction of the atomizing gas. Accordingly, the groove structures 10c formed on the opposite peripheral sides and the fitting of the aerosol generating device, for example, the groove structures 10c and the inner wall of the ventilation structure enclose an atomizing passage in which the atomizing gas is heated from the atomized liquid to atomize the formed aerosol, and then discharged to the outside by the ventilation structure. And, the groove structures 10c are respectively opened on the two opposite peripheral sides, that is, the notch orientations of the groove structures 10c are opposite.

The heating elements 20 are disposed on the groove walls of the corresponding groove structures 10c. Here, the atomized liquid adheres to the groove wall of the groove structure 10c of the atomizing carrier 10, and the atomized liquid is atomized and lifted in the groove structure 10c by the heating action of the heating element 20. Of course, the first end surface 10a, the second end surface 10b and the peripheral side wall of the atomizing carrier 10, which is not provided with the groove structure 10c, can also be used as an adsorption surface of the atomized liquid, and meanwhile, the atomizing carrier 10 is made of porous materials, for example, the atomizing carrier 10 is made of ceramic materials, so that the atomized liquid has a certain storage capacity, and is helpful for continuously atomizing and rising the atomized gas, and avoiding the phenomenon of dry burning. Wherein the porous material includes, but is not limited to, porous ceramics, porous glass, porous metal, cotton, fiber or a composite material composed of at least two of the above.

In general, the atomizing carrier 10 has a cubic structure, and can be assembled with an aerosol generating device adapted thereto, and of course, the shape and structure of the atomizing carrier 10 are not limited according to actual use conditions, so as to be adapted to the aerosol generating device.

Illustratively, the atomizing carrier 10 has a columnar structure, and the columnar structure has a circular, elliptical, square, or the like cross-sectional shape in the radial direction. Of course, the cross-sectional shape of the columnar structure in the radial direction may also be an irregular polygonal structure, for example, a star shape or the like, depending on the design of the internal structure of the ventilation structure of the aerosol-generating device.

Meanwhile, the concave shape of the groove structures 10c formed in the direction parallel to the first end face 10a or the second end face 10b is not limited, and the size of the concave shape of the two groove structures 10c may not be limited.

Illustratively, to facilitate the placement of the heater 20 and the adequate contact with the heater 20, the bottom walls of the grooves of the groove structure 10c are planar to meet the need for adequate contact with the heater 20, and the side walls of the groove structure 10c may also be similarly placed for the heater 20. Of course, the bottom wall of the groove structure 10c is also an arc surface according to the shape design of the heating element 20, or a pit or a protrusion is formed on the bottom wall of the groove structure 10c to adapt to the shape structure of the current heating element 20.

Illustratively, the concave shapes of the two groove structures 10c are identical, and the magnitudes of the concave shapes are also identical. Alternatively, the concave shapes of the two groove structures 10c are the same, however, there is a difference in the magnitudes of the concave shapes of the two groove structures 10c.

In the assembled state with the aerosol generating device, the first end surface 10a and the second end surface 10b of the atomizing carrier 10 are perpendicular or substantially perpendicular to the flow direction of the atomizing gas, i.e., the extending direction of the groove structure 10c is the flow direction of the atomizing gas.

The aerosol generating assembly 100 provided by the application forms a groove structure 10c penetrating through the first end face 10a and the second end face 10b on any two opposite peripheral side faces of the aerosol generating carrier 10, namely, the aerosol generating assembly 100 is provided with two atomizing channels for heating and atomizing an atomized liquid to form aerosol and enabling the aerosol to pass through, the groove structure 10c is provided with a larger surface area, the heating body 20 is convenient to install and set, and meanwhile, when the aerosol generating assembly 100 is assembled in an aerosol generating device, the groove structure 10c does not reduce the atomizing surface area due to the assembling space. And, the extending direction of the groove structure 10c is the flow direction of the atomizing gas, so that the transmission path of the atomizing gas is shortened, and the energy consumption of the atomizing gas is reduced. In summary, the atomization amount of the atomized gas generated by the aerosol generating assembly 100 is larger, the transmission path is not turned, the whole transmission process is smoother, the probability of condensation of the atomized gas in the transmission process is further reduced, and the sustainability of the atomization effect is ensured.

Referring to fig. 4, in one embodiment, the atomizing carrier 10 has a circular outline in a cross-sectional direction parallel to the first end face 10a, and it is understood that the atomizing carrier 10 has a cylindrical structure, and can be used to adapt to a ventilation structure in which the radial cross-section of the aerosol generating device is also circular. The groove structure 10c is open on the arc-shaped circumferential side of the atomizing carrier 10. That is, the peripheral side surface of the atomizing carrier 10 in the present embodiment is a continuous whole surface, and therefore, the groove structure 10c can be formed to be recessed inward at any two opposite positions of the peripheral side surface. The walls of the two groove structures 10c are enclosed with the inner wall of the ventilation structure to form an atomization channel.

Referring to fig. 3 and 5, in one embodiment, the outline of the atomizing carrier 10 in the cross-sectional direction parallel to the first end face 10a is a polygonal structure, and it is understood that the polygonal structure may be square, diamond, regular hexagon, etc., and the atomizing carrier 10 is also adapted to a ventilation structure having the same cross-sectional shape. In this embodiment, there are a plurality of peripheral sides of the atomizing carrier 10, and the transition between two adjacent peripheral sides also belongs to the peripheral sides of the atomizing carrier 10, so that the groove structure 10c can be formed on the peripheral sides or the top corners of the atomizing carrier 10, where the top corners are the transition between two adjacent peripheral sides.

Illustratively, as shown in fig. 3, the atomizing carrier 10 has a square outline in a cross-sectional direction parallel to the first end face 10a, and is provided with corresponding groove structures 10c at opposite vertex angles.

As shown in fig. 5, the atomizing carrier 10 has a regular octagonal outer shape in a cross-sectional direction parallel to the first end face 10a, and corresponding groove structures 10c are provided on the opposite peripheral side faces.

Specifically, referring to fig. 1, the polygonal structure is rectangular, and the number of the groove structures 10c is two; each groove structure 10c is respectively formed on two opposite peripheral sides of the atomizing carrier 10. It will be appreciated that when the concave shapes of the two groove structures 10c are the same, the magnitudes of the concave shapes are the same, and the shape of the groove structures 10c in the cross-sectional direction of the first end face 10a is of the "]" type, and the two groove structures 10c are symmetrical about the central axis of the aerosol-generating device, the shape of the aerosol-generating device 10 in the cross-sectional direction of the first end face 10a is of the "H" type, or, approximately, the "H" type, then the cross-sectional shape of the aerosol-generating device 10 is of the "H" type, the overall structural strength is high, particularly the compressive strength in the direction of the peripheral side face of the non-opened groove structure 10c is higher, and the Zhou Cemian of the two non-opened groove structures 10c are flat and parallel, so as to be adapted to the ventilation structure of the aerosol-generating device. Of course, in embodiments thereof, the concave shape of the two groove structures 10c, the size of the concave shape, and the specific placement positions of the two groove structures 10c may be adjusted accordingly.

Referring to fig. 6 and 11, the heat generating body 20 includes a connection portion 21 and two heat generating portions 22 connected to opposite ends of the connection portion 21, each heat generating portion 22 being located at a corresponding groove structure 10c.

It is understood that the connecting portion 21 and the two heat generating portions 22 form an integral structure, that is, three are connected in series. In the unassembled state with the atomizing carrier 10, the connecting portion 21 and the two heat generating portions 22 are arranged in a straight line, which is convenient for production and manufacture, for example, by a punching or etching process. In this way, the manufacturing accuracy of the connection portion 21 and the heat generating portion 22 is controllable, and the heat generating power of the connection portion 21 and the heat generating portion 22 can be adjusted according to the use requirement. For example, the areas, thicknesses, shape structures, and the like of the heat generating portion 22 and the connecting portion 21 are adjusted. When assembled with the atomizing carrier 10, the two heating parts 22 are bent in opposite directions to form a substantially U-shaped structure with the connecting part 21, and at this time, the connecting part 21 can be embedded into the atomizing carrier 10 and penetrate through the bottom walls of the two opposite groove structures 10c, and the connection stability of the whole heating body 20 and the atomizing carrier 10 is improved by utilizing the connection relation between the connecting part 21 and the atomizing carrier 10.

Of course, the connection portion 21 may be provided astride the atomizing carrier 10. That is, the connecting portion 21 is at least partially provided astride the first end surface 10a or the second end surface 10b. At this time, the connection portion 21 may be located above the first end face 10a or the second end face 10b of the atomizing carrier 10, not in contact with the first end face 10a or the second end face 10b, or may abut against the first end face 10a or the second end face 10b, or even the connection portion 21 may be partially embedded in the first end face 10a or the second end face 10b.

In this way, when the first end surface 10a or the second end surface 10b is the air inlet end of the groove structure 10c, the connection portion 21 can preheat the air entering the groove structure 10c, so that the supercooled air is prevented from cooling the heating portion 22, and the heating temperature of the heating portion 22 can be maintained within a certain range.

When the first end surface 10a or the second end surface 10b is the air outlet end of the groove structure 10c, the condensation phenomenon occurs due to the sudden drop of the air temperature when the aerosol formed in the groove structure 10c flows out, and the formed condensate is heated and atomized again by the connecting portion 21, so that the occurrence probability of the condensation phenomenon at the air outlet end of the atomized carrier 10 is reduced.

If the first end surface 10a or the second end surface 10b is the liquid suction surface in direct contact with the atomized medium, the connection portion 21 can preheat the atomized medium on the liquid suction surface, so that the fluidity of the atomized medium is improved, the dry burning phenomenon is reduced, and meanwhile, components with lower atomization temperature in the atomized medium can be atomized at the connection portion 21 to form aerogel, so that the composition of the final aerogel can be enriched, and the sucking taste is improved.

Referring to fig. 3, specifically, in one embodiment, the distance from the groove side wall of the groove structure 10c to the adjacent side wall of the atomizing carrier 10 is T1, the distance between the groove bottom walls of the two groove structures 10c is T2, and T2 is greater than T1. It will be appreciated that in the present embodiment, the shape of the groove structure 10c in the cross-sectional direction of the first end face 10a is "]", and the shape structure of the atomizing carrier 10 in the cross-sectional direction of the first end face 10a is square. Here, it is defined that the direction in which the atomizing carrier 10 is provided with the groove structure 10c is a length direction and the direction in which the atomizing carrier 10 is not provided with the groove structure 10c is a width direction, then the atomizing carrier 10 is composed of an abdomen portion and two wing portions protruding on the abdomen portion in the width direction of the atomizing carrier 10, and the thickness of the wing portions is T1 and the thickness of the abdomen portion is T2. When T2 is greater than T1, can guarantee the structural strength of the wing portion of atomizing carrier 10, be convenient for produce and make and the required assembly holding power of atomizing carrier 10, and then promote the structural strength of whole atomizing carrier 10.

Specifically, T2 is more than or equal to 1.5mm, and T1 is more than or equal to 0.8mm. It will be understood that when the thickness of the abdomen portion of the atomizing carrier 10 is 1.5mm or more and the thickness of the wing portion is 0.8mm or more, the liquid guiding surface area of the atomizing carrier 10 is larger and the area of the groove inner surface of the groove structure 10c is relatively reduced on the basis of ensuring the overall structural strength of the atomizing carrier 10, wherein the area of the groove inner surface of the groove structure 10c is the atomization generation area of the atomizing carrier 10, and thus, the liquid guiding surface area of the atomizing carrier 10 is larger than the atomization generation area on the whole, and the occurrence of the phenomenon of "dry burning" caused by insufficient liquid supply can be avoided.

Referring to fig. 3, specifically, the groove width T3 of the groove structure 10c is greater than the groove depth T4 of the groove structure 10c. It will be appreciated that the groove structure 10c forms a wide and shallow channel on the peripheral side of the atomizing carrier 10, so that the junction of the wing portion and the web portion of the atomizing carrier 10 has a higher structural strength and is less likely to break at the junction. And, the groove width of the groove structure 10c is wider, if the groove bottom wall of the groove structure 10c is used as the installation surface of the heating body 20, then the heating area of the atomizing carrier 10 is relatively larger, the whole atomizing carrier 10 heats more uniformly, and meanwhile, the heating body 20 can obtain a larger installation surface, so that the installation is more convenient.

Referring to fig. 2, in one embodiment, the heat generating body 20 has a heat generating region 20a, and a height H2 of the heat generating region 20a is greater than one half of a height H1 of the atomizing carrier 10 in an extending direction of the groove structure 10c. It will be appreciated that the larger the heat generating region 20a of the heat generating body 20, the larger the heat generating area itself, so that heat can be transferred to the atomizing carrier 10.

For example, the heat generating body 20 may be a heat generating sheet formed by an etching or punching process. When the atomizing carrier 10 is made of ceramic, the heat generating sheet may be pre-installed with the blank of the atomizing carrier 10, and then the heat generating sheet and the blank of the atomizing carrier 10 are sintered simultaneously to form the aerosol generating assembly 100.

Alternatively, the heat-generating body 20 may be provided with a heat-conductive paste on the atomizing carrier 10 by a coating or printing process, and at this time, the atomizing carrier 10 may be a ceramic carrier after sintering molding.

Referring to fig. 6, in one embodiment, the heating element 20 includes a connection portion 21 and two heating portions 22 connected to the connection portion 21, the heating portions 22 are disposed in the groove structures 10c in a one-to-one correspondence, and the connection portion 21 penetrates through the atomizing carrier 10 to bottom walls of the two groove structures 10c and is connected to a same end of the two heating portions 22. As can be appreciated, the connection portion 21 is connected in series with the two heat generating portions 22, and the ends of the two heat generating portions 22 away from the connection portion 21 are electrically connected to the positive electrode and the negative electrode of the power supply battery, respectively, so as to ensure the heat generation of the heat generating portions 22. The connection portion 21 penetrates through the atomizing carrier 10 and penetrates through the bottom walls of the two opposite groove structures 10c, so that all or most of the connection portion 21 is limited by the atomizing carrier 10, after the atomizing carrier 10 is sintered and hardened, the connection portion 21 is limited by the atomizing carrier 10 and cannot be separated from the atomizing carrier 10 in the direction from the first end face 10a toward the second end face 10b, and the connection portion 21 cannot be separated from the atomizing carrier 10 in the opening direction of the two groove structures 10c when the two heating portions 22 are abutted against the groove walls of the corresponding groove structures 10c, and finally, the heating element 20 can be stably arranged on the atomizing carrier 10.

Referring to fig. 1 and 6, in one embodiment, at least one heat generating portion 22 is tiled on the bottom wall of the corresponding groove structure 10c. It will be appreciated that the bottom wall of the recess structure 10c is adapted to the shape and configuration of the heat generating portion 22. For example, in order to facilitate the heat-generating portion 22 being laid in the groove structure 10c and being sufficiently contacted with the heat-generating portion 22 of the heat-generating body 20 to the groove structure 10c, the bottom wall of the groove structure 10c may be a plane, and the heat-generating portion 22 may be a sheet structure, so as to satisfy the sufficient contact between the two and avoid the occurrence of warpage or unevenness. Of course, the bottom wall of the recess structure 10c may be adapted according to the shape of the heat generating portion 22 of the heat generating body 20. For example, the heat generating portion 22 is provided in an arc-shaped structure, and then the bottom wall of the groove structure 10c may also be designed as a corresponding arc surface.

One of the heating parts 22 can be arranged on the bottom wall of the groove structure 10c in a tiling manner, and the two heating parts 22 can be tiled on the bottom wall of the corresponding groove structure 10c, and meanwhile, the shape design of the two heating parts 22 is matched with the bottom wall of the groove structure 10c, and the two heating parts can be identical or the same.

Alternatively, at least a portion of the at least one heat generating portion 22 is embedded in the bottom wall of the corresponding groove structure 10c in a direction perpendicular to the bottom wall of the groove structure 10c. It should be understood that the heat generating portion 22 is embedded in the bottom wall of the groove structure 10c, that is, the plane thereof is perpendicular to the plane of the bottom wall of the groove structure 10c, and it should be noted that the perpendicular is not strictly an absolute perpendicular, but a perpendicular relationship defined during the machining process, so that a corresponding error is allowed.

One of the heating parts 22 may be vertically embedded on the bottom wall of the groove structure 10c, or both the two heating parts 22 may be vertically embedded on the bottom wall of the corresponding groove structure 10c, and meanwhile, the partial embedding means that the heating part 22 is locally located in the bottom wall of the groove structure 10c, and the local part only needs to belong to the heating part 22, and the area embedded in the bottom wall of the groove structure 10c is not limited. Of course, the heat generating portion 22 may also be completely embedded in the bottom wall of the recess structure 10c, i.e. in the atomizing carrier 10.

Referring to fig. 1, in an embodiment, when the groove structure 10c has a bottom wall and a side wall surrounding the bottom wall, the heat generating portion 22 may be selectively laid on the bottom wall of the groove structure 10c, and the heat generating portion 22 extends toward the side wall of the groove structure 10c and is embedded in the side wall of the groove structure 10c or a connection between the side wall of the groove structure 10c and the bottom wall of the groove structure 10c. It can be appreciated that the heat generating portion 22 may be selectively connected and fixed to the side wall of the groove structure 10c or the connection between the side wall and the bottom wall in a plane parallel to the bottom wall of the groove structure 10c, so as to reduce the warpage of the heat generating portion 22 beyond the bottom wall of the groove structure 10c, and improve the stability of the heat generating portion 22 in the groove structure 10c.

Specifically, referring to fig. 1, when the groove structure 10c has opposite sidewalls, then opposite sides of the heat generating portion 22 in a flat state extend toward the sidewalls of the corresponding groove structure 10c. It will be appreciated that at least two opposite sides of the heat generating portion 22 are in connection with the side wall of the recess structure 10c or the connection between the side wall and the bottom wall thereof, so that the connection between the heat generating portion 22 and the wall of the recess structure 10c is stable.

In one embodiment, the peripheral side has at least one liquid suction surface in contact with the atomizing liquid. It will be appreciated that when the atomizing carrier 10 has a circular shape in the cross-sectional direction parallel to the first end face 10a, the peripheral side face of the atomizing carrier 10 is a continuous whole face, and the liquid suction face is formed on the peripheral side face where the groove structure 10c is not provided.

For example, when the atomizing carrier 10 has a cylindrical structure, its outline in the cross-sectional direction parallel to the first end face 10a is a circular structure, and at this time, the liquid suction face is on an arc-shaped peripheral side face where the groove structure 10c is not provided. In the example, the number of liquid-absorbing surfaces is also two and is arranged opposite to each other, so that the liquid-absorbing surface of the atomizing carrier 10 corresponds to the atomized liquid inlet of the aerosol generating device.

For example, when the atomizing carrier 10 is of a cubic structure, its outline in a cross-sectional direction parallel to the first end face 10a is square, and the groove structure 10c is opened on the peripheral side face of the atomizing carrier 10. Then, two of the opposite peripheral sides are provided with groove structures 10c, and the other two opposite peripheral sides are liquid suction surfaces.

For example, when the atomizing carrier 10 is of a cubic structure, its outline in the cross-sectional direction parallel to the first end face 10a is square, and the groove structure 10c is opened on the apex angle of the atomizing carrier 10. That is, if the recess structures 10c are formed at two opposite vertex angles, then the atomizing carrier 10 still has four peripheral sides at this time, and therefore, one or several of the peripheral sides may be selected as the liquid suction surface.

Alternatively, in other embodiments, the first end surface 10a and/or the second end surface 10b act as a meniscus in contact with the atomizing liquid. It will be appreciated that the aerosol generating assembly 100, when assembled with an aerosol generating device, may have an aerosol inlet port in communication with the first end face 10a and/or the second end face 10b, i.e. the aerosol may be in direct or indirect contact with the first end face 10a and/or the second end face 10b by the aerosol inlet port.

Alternatively, in other embodiments, at least one peripheral side of the atomizing carrier 10 may be selected as a liquid-absorbing surface in contact with the atomizing liquid, and the first end surface 10a and/or the second end surface 10b may be selected as a liquid-absorbing surface in contact with the atomizing liquid.

For example, when the atomizing carrier 10 has a cylindrical structure, both end surfaces, i.e., the first end surface and the second end surface 10b, of the atomizing carrier 10 may be selectively used as the liquid suction surface, and at the same time, the arc-shaped peripheral side surface not provided with the groove structure 10c may be selectively used as the liquid suction surface.

Alternatively, the peripheral side of the atomizing carrier 10 serves as a liquid suction surface in contact with the atomized liquid.

Referring to fig. 7 to 10, in one embodiment, a liquid collecting structure 10d is formed on the liquid suction surface of the atomizing carrier 10. Here, the liquid-collecting structure 10d further adsorbs and gathers the atomized liquid.

It will be appreciated that the liquid collecting structure 10d can increase the total amount of adhering atomized liquid on the liquid suction surface. The liquid-collecting structure 10d can collect liquid from several angles:

the liquid collecting structure 10d can increase the contact area between the liquid suction surface and the atomized liquid. For example, the liquid collecting structure 10d is a convex portion or a concave portion formed on the liquid suction surface, and forming a plurality of convex portions or concave portions on the liquid suction surface further increases the liquid suction area, that is, can collect more total amount of atomized liquid, than the liquid suction surface is for a liquid suction surface opposite to the liquid inlet hole. Here, the convex portions are not limited to the structures of the convex teeth, convex ribs, and the like, and the concave portions are not limited to the pits, grooves, and the like.

The coalescing structure 10d may provide a reservoir of aerosol to increase the total amount of aerosol on the aerosol generating assembly 100. For example, the liquid collecting structure 10d is a liquid collecting member formed on the liquid suction surface, and the liquid collecting member may be made of a capillary material, such as a cotton material, or the like. In this way, the liquid collecting member collects the atomized liquid and then conveys the atomized liquid to the liquid suction surface.

Referring to fig. 7, in one embodiment, the liquid collecting structure 10d is a non-planar structure formed on the liquid absorbing surface. It will be appreciated that the liquid collecting structure 10d is integrally formed with the liquid suction surface, i.e., the non-planar structure is integrally formed with the liquid suction surface, and can allow the liquid suction area to be increased. The non-planar structure is a structure opposite to the planar structure, that is, a structure capable of causing the liquid-absorbent area to be in a state of the non-planar structure may be referred to as a non-planar structure.

Specifically, the non-planar structure may be a protrusion and/or a recess formed on the liquid-absorbent surface, wherein the protrusion may be a protrusion, a bead, or the like, and the recess may be a depression, a groove, or the like. The shape and structure of the convex portions and concave portions are not limited, the number is not limited, and the positions of the convex portions and concave portions on the liquid suction surface are not limited. For example, a plurality of convex portions may be formed on the liquid surface in an array, a plurality of concave portions may be formed on the liquid surface in an array, or a plurality of concave portions and convex portions may be formed on the liquid surface in an array.

Referring to fig. 8, in one embodiment, the liquid collecting structure 10d is a concave structure or a convex structure formed on the liquid suction surface. Similarly, the concave surface structure or the convex surface structure and the liquid absorbing surface are integrally formed, and the convex surface structure or the concave surface structure can increase the area of the liquid absorbing surface. The convex structure is a structure protruding from the liquid suction surface and extending outwards. Here, the convex structure is not limited in the convex position and convex shape on the liquid suction surface. For example, the convex structure may be convex in the middle of the liquid suction surface, and the cross section of the convex structure in the protruding direction is arc-shaped. It should be understood that the concave structure is opposite to the convex structure in the protruding direction, and the concave structure is formed by recessing the liquid absorbing surface inward, for example, the concave structure may be concavely disposed in the middle of the liquid absorbing surface, and the section of the concave structure in the recessing direction is arc-shaped.

Referring to fig. 8, in one embodiment, the atomizing carrier 10 has two opposite liquid suction surfaces, a convex structure is respectively disposed in the middle of two opposite outward surfaces of the two liquid suction surfaces, and the two convex structures are symmetrical about the symmetry center of the two liquid suction surfaces, so that the two liquid suction surfaces protrude outwards to form an outwards convex arc surface, and compared with the planar liquid suction surface, the contact area between the outwards convex arc liquid suction surface and the oil is larger, and more oil can be adsorbed and accumulated in unit time, so that the liquid supply amount of the aerosol generating assembly 100 is greater than or equal to the atomization amount thereof.

Referring to fig. 9, in another embodiment, the atomizing carrier 10 has two opposite liquid suction surfaces, a concave structure is respectively disposed in the middle of two opposite outward surfaces of the two liquid suction surfaces, and the two concave structures are symmetrical about the symmetry center of the two liquid suction surfaces, so that the two liquid suction surfaces are concave inward to form a concave arc surface, and compared with the planar liquid suction surface, the contact area between the concave arc liquid suction surface and the oil is larger, and more oil can be adsorbed and accumulated in unit time, so that the liquid supply amount of the aerosol generating assembly 100 is greater than or equal to the atomization amount thereof. At the same time, the distance that the liquid suction surface conveys the atomized liquid to the middle area of the atomized carrier 10 is shortened, so that the aerosol generating assembly 100 can provide enough atomized liquid when in operation, and the problem of dry burning caused by insufficient liquid supply is prevented. In addition, because the temperature of the area defined by the atomizing carrier 10 between the bottom walls of the two groove structures 10c is relatively high due to the concave portion formed by the concave portion of the liquid suction surface toward the middle of the atomizing carrier 10, the liquid suction surface is concave in the direction of the area, so that the temperature of the middle position of the atomizing carrier 10 can transfer the redundant heat to the atomized liquid and preheat the atomized liquid, the fluidity of the atomized liquid can be improved, and meanwhile, the problem of dry burning caused by the overhigh local temperature is also prevented.

Referring to fig. 10, in one embodiment, the liquid collecting structure 10d is a groove array formed on the liquid suction surface, that is, the liquid collecting structure 10d has a groove array formed by a plurality of concave portions. It will be appreciated that the array of slots is a structure of slots distributed in an array and, therefore, the form of the array distribution is not limited. For example, the groove structures may be spaced apart along the width or length of the liquid surface; alternatively, each groove structure is arranged at intervals along the width and length directions of the liquid suction surface; or, each groove structure is arranged at intervals along the direction forming an included angle with the width or length direction of the liquid suction surface; or, each groove structure takes the center of the liquid suction surface as the center of the circle, and is arranged in concentric circles at intervals. Meanwhile, the shape and structure of the groove array are not limited. For example, the cross-section of the slot structure of the slot array may be square, triangular, trapezoidal, or circular arc, etc. The groove structure of the groove array may be a groove structure penetrating the liquid surface along the width or length of the liquid surface, or may be a non-penetrating groove structure.

Preferably, referring to fig. 10, in one embodiment, the atomizing carrier 10 has two oppositely disposed liquid suction levels, with an array of grooves formed on opposite outward facing surfaces of the two liquid suction levels, respectively. The groove arrays are arranged at intervals along the length direction of the liquid suction surface, and the cross section of the groove structure of the groove arrays forms an arc shape. Thus, the area of the liquid suction surface is increased by the groove array, and meanwhile, each groove structure of the groove array has the function of storing oil. In particular, the installation position of the aerosol generating assembly 100 in the aerosol generating device is in an upright state, so that when the extending direction of the groove array on the liquid suction surface is the same as the height direction of the aerosol generating device, the aerosol generating assembly is attached to the oil liquid on the liquid suction surface, and can flow along the groove structure of the groove array under the action of gravity, which is more beneficial to improving the speed of the oil liquid in the oil bin of the aerosol generating device attached to the surface of the atomization carrier 10, and the oil liquid can continuously supplement the atomization carrier 10 to provide the liquid supply amount of the atomization carrier 10 in unit time.

Embodiments of the present application also provide an aerosol-generating device comprising the aerosol-generating assembly 100 described above.

According to the aerosol generating device, on the basis of the aerosol generating assembly 100, the aerosol generating device obtains higher atomization amount in unit time, and the experience effect of a user is better.

Referring to fig. 11, in some embodiments, the aerosol generating device includes a liquid storage cavity, a vent pipe 200 disposed in the liquid storage cavity, an air flow channel is defined in the vent pipe 200, oil inlet holes 201 communicating the liquid storage cavity and the air flow channel are formed on opposite side walls of the vent pipe 200, the aerosol generating assembly 100 is installed in the vent pipe 200, and a peripheral side surface of the aerosol generating assembly 100, which is not provided with the groove structure 10c, corresponds to the corresponding oil inlet holes 201, and atomized liquid in the liquid storage cavity enters the vent pipe 200 through the oil inlet holes 201 and is adhered to the peripheral side surface. The groove surface of the groove structure 10c and the inner wall of the ventilation pipe 200 are enclosed to form an atomization channel, the heating body 20 heats the atomization carrier 10, and the atomized liquid is heated and atomized in the groove structure 10c and is discharged to the outside from the outlet of the ventilation pipe 200.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
