Abstract

The application is suitable for the technical field of aerosol generating devices, and provides an atomization assembly and an atomization device. The atomization assembly comprises an atomization core and a liquid storage structure. The atomization core has a heating body. The liquid storage structure is sleeved on the outer periphery of the atomization core. The porosity of the liquid storage structure increases along the direction from far to close to the heating body. The above structure design not only enables the aerosol substrate in the liquid storage structure to fully permeate into the atomization core and be atomized by the heating body of the atomization core, thereby reducing the residual amount of the aerosol substrate in the liquid storage structure, but also ensures that the aerosol substrate around the atomization core is sufficient, thereby avoiding dry burning of the heating body due to liquid supply lag.

Description

Technical Field

[0001] This application belongs to the technical field of aerosol generation devices, and more specifically, relates to an atomizing component and atomizing device. Background Technology

[0002] The atomizing component is the core functional unit in an atomizing device that converts the aerosol matrix into aerosol. In related technologies, the atomizing component includes an atomizing core and a liquid storage structure. The liquid storage structure surrounds the atomizing core and absorbs the aerosol matrix through capillary action, conducting it to the heating element inside the atomizing core to maintain a continuous liquid supply.

[0003] However, the aerosol matrix in the liquid storage structure experiences significant resistance during transport, preventing it from fully entering the atomizing core for atomization. Utility Model Content

[0004] The purpose of this application is to provide an atomizing component and atomizing device, which aims to solve the technical problem in the related art that the aerosol matrix in the liquid storage structure cannot fully enter the atomizing core for atomization.

[0005] To achieve the above objectives, according to one aspect of this application, an atomizing component is provided, including an atomizing core and a liquid storage structure. The atomizing core has a heating element, and the liquid storage structure is sleeved on the outer periphery of the atomizing core. The pore density of the liquid storage structure increases from the direction away from the heating element to the direction closer to the heating element.

[0006] According to another aspect of this application, an atomizing device is provided, including an atomizing shell, a power supply component, and the aforementioned atomizing component. The atomizing core, a liquid storage structure, and the power supply component are disposed inside the atomizing shell, and the power supply component is electrically connected to the atomizing component.

[0007] The beneficial effect of the atomizing component provided in this application is that the liquid storage structure near the heating element adopts a high pore density design, while the liquid storage structure far from the heating element adopts a low pore density design. This structural design makes the liquid storage structure a gradient structure.

[0008] On the one hand, the high-porosity sections of the liquid reservoir are closer to the heating element, resulting in lower resistance to aerosol matrix transmission. This facilitates rapid penetration of the aerosol matrix into the heating element of the atomizer core, ensuring sufficient penetration and atomization of the aerosol matrix within the reservoir, thus reducing residual aerosol matrix. Simultaneously, it ensures ample aerosol matrix around the atomizer core, preventing dry burning of the heating element due to delayed liquid supply, thus guaranteeing optimal flavor and extending the atomizer core's lifespan. Furthermore, the rapid wicking properties of the high-porosity sections of the liquid reservoir allow the aerosol matrix to penetrate more quickly to the vicinity of the atomizer core after initial use or prolonged inactivity, reducing cavitation and improving startup response speed.

[0009] On the other hand, the low-porosity sections of the liquid storage structure are further away from the heating element. Their surface tension constrains the slow release of the aerosol matrix, preventing localized saturation of the heating element due to excessively rapid permeation. Simultaneously, the lower-porosity sections of the liquid storage structure exhibit stronger capillary action, enabling unidirectional transport of the aerosol matrix towards the heating element and suppressing backflow caused by pressure changes or tilting.

[0010] On the other hand, the gradient transmission of the liquid storage structure avoids local accumulation or shortage of aerosol matrix in the liquid storage structure, which not only makes the distribution of aerosol matrix around the atomizing core more uniform, but also improves the consistency of aerosol concentration generated during atomization and improves the stability of taste when the user inhales.

Therefore, they should not be construed as limitations on this application.

"And / or" in this application is merely a description of the relationship between the related objects, indicating that there can be three relationships.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] As described in the background section, the atomizing component is the core functional unit in an atomizing device that converts an aerosol matrix into an aerosol. In related technologies, the atomizing component includes an atomizing core and a liquid storage structure. The liquid storage structure surrounds the atomizing core and absorbs the aerosol matrix through capillary action, conducting it to the heating element within the atomizing core to maintain a continuous liquid supply. However, the aerosol matrix in the liquid storage structure experiences significant resistance during transport, preventing it from fully entering the atomizing core for atomization.

[0035] Reference Figures 1 to 8 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides an atomizing component, which includes an atomizing core 100 and a liquid storage structure 200. The atomizing core 100 has a heating element 110, and the liquid storage structure 200 is sleeved on the outer periphery of the atomizing core 100. The pore density of the liquid storage structure 200 increases from the direction away from the heating element to the direction closer to the heating element.

[0036] In this embodiment, the heating element 110 is shaped as a filament, mesh, sheet, rod, column, or a combination of these shapes. The heating element 110 is made of metal, ceramic, graphene, or other materials. The liquid storage structure 200 surrounds the atomizing core 100, and the liquid storage structure 200 is made of any one of the following: liquid storage cotton, porous aerogel, non-woven fabric, fiber bundle, microporous ceramic, or other liquid storage media.

[0037] In this application, the liquid storage structure 200 near the heating element 110 adopts a high pore density design, while the liquid storage structure 200 away from the heating element 110 adopts a low pore density design. This structural design makes the liquid storage structure 200 form a gradient structure.

[0038] On the one hand, the high-porosity portion of the liquid storage structure 200 is closer to the heating element 110, resulting in lower resistance to aerosol matrix transmission. This facilitates rapid penetration of the aerosol matrix into the heating element 110 of the atomizing core 100. This not only allows the aerosol matrix within the liquid storage structure 200 to fully penetrate into the atomizing core 100 and be atomized by the heating element 110, reducing residual aerosol matrix within the liquid storage structure 200, but also ensures sufficient aerosol matrix around the atomizing core 100, preventing dry burning of the heating element 110 due to delayed liquid supply, thus ensuring optimal atomized flavor and extending the lifespan of the atomizing core 100. Furthermore, the rapid oil-conducting characteristics of the high-porosity portion of the liquid storage structure 200 allow the aerosol matrix to penetrate more quickly to the vicinity of the atomizing core 100 after initial use or prolonged resting, reducing dry suction and improving start-up response speed.

[0039] On the other hand, the low-porosity sections of the liquid storage structure 200 are further away from the heating element 110. Their surface tension constrains the slow release of the aerosol matrix, preventing localized saturation of the heating element 110 due to excessively rapid permeation of the aerosol matrix. Simultaneously, the lower-porosity sections of the liquid storage structure 200 exhibit stronger capillary action, enabling unidirectional transport of the aerosol matrix towards the heating element 110 and suppressing backflow of the aerosol matrix caused by pressure changes or tilting.

[0040] On the other hand, the gradient transmission of the liquid storage structure 200 avoids local accumulation or shortage of aerosol matrix in the liquid storage structure 200, which not only makes the distribution of aerosol matrix around the atomizing core 100 more uniform, but also improves the consistency of aerosol concentration generated during atomization and improves the stability of taste when the user inhales.

[0041] Reference Figures 1 to 8 In one embodiment, the heating element 110 is arranged along a first direction, and the liquid storage structure 200 includes a plurality of liquid storage areas 210 arranged sequentially along a second direction. The second direction is parallel to the first direction, intersects the first direction, or is the circumferential direction of the liquid storage structure 200. Among two adjacent liquid storage areas 210, the one closer to the heating element 110 is the first liquid storage area 210a, and the other is the second liquid storage area 210b. The pore density of the first liquid storage area 210a is higher than that of the second liquid storage area 210b.

[0042] In this embodiment, the first direction is a straight line. The first direction can refer to the positive direction or the negative direction. The first direction shown in the accompanying drawings is only an illustration. The length direction of the heating element 110 is parallel to the first direction, and the atomizing core 100 is arranged along the first direction as a whole. That is, the length direction of the entire structure of the atomizing core 100 is parallel to the first direction. The length direction of the liquid storage structure 200 is parallel to the first direction; the liquid storage area 210 is a liquid storage layer or a liquid storage block, and the extension length of two adjacent liquid storage areas 210 in the second direction is equal, and there is no gap between two adjacent liquid storage areas 210. The liquid storage areas 210 are integrally formed parts; it is understood that the liquid storage areas 210 may not be arranged sequentially along the second direction, but may be arranged irregularly, for example, a part of the structure of the first liquid storage area 210a may be inserted into the second liquid storage area 210b; when the liquid storage areas 210 are arranged sequentially along the second direction, the extension length of two adjacent liquid storage areas 210 in the second direction may also be different, and there may be gaps between two adjacent liquid storage areas 210. When the second direction is parallel to or intersects the first direction, the second direction is a straight line. The second direction can refer to the positive direction of the second direction or the opposite direction of the second direction. The second direction shown in the attached figure is only a schematic diagram. When the second direction is the circumferential direction of the liquid storage structure, the second direction is the direction along the tangent of the circumferential surface of the liquid storage structure, and the second direction is a curved direction.

[0043] Furthermore, the prefixes "first" and "second" preceding "liquid storage area 210" are merely names; among multiple liquid storage areas 210, the liquid storage area 210 located between two liquid storage areas 210 can be either the first liquid storage area 210a or the second liquid storage area 210b, depending on the comparison object, and is not specifically limited here.

[0044] In this application, the first liquid storage region 210a near the heating element 110 adopts a high pore density design, and the second liquid storage region 210b far away from the heating element 110 adopts a low pore density design. This structural design makes the liquid storage structure 200 form a gradient structure.

[0045] Reference Figure 3 , Figure 5 , Figure 7 as well as Figure 8 In one embodiment, the second direction is perpendicular to the first direction. In this embodiment, the liquid storage structure 200 is cylindrical in shape, and the second direction is parallel to the radial direction of the liquid storage structure 200. The radial direction of the liquid storage structure 200 refers to the radial direction from the central axis of the liquid storage structure 200 to the outer peripheral surface of the liquid storage structure 200, and this direction is perpendicular to the axial direction of the liquid storage structure 200. Of two adjacent liquid storage areas 210, the one closer to the overall structure of the atomizing core 100 is the first liquid storage area 210a, and the one farther from the overall structure of the atomizing core 100 is the second liquid storage area 210b. The second liquid storage area 210b surrounds the first liquid storage area 210a. It is understood that the angle between the second direction and the first direction can also be an acute angle.

[0046] The design, with the second direction perpendicular to the first direction, ensures that multiple liquid storage zones 210 are evenly distributed along a direction perpendicular to the length of the heating element 110. This not only aligns the aerosol matrix's transmission path with the length of the heating element 110, effectively reducing transmission resistance and improving transmission speed and efficiency, but also promotes uniform circumferential penetration of the aerosol matrix around the heating element 110, ensuring a uniform distribution of the aerosol matrix and improving the atomized taste. Furthermore, it eliminates the need for tilted stacking of the liquid storage zones 210, resulting in tighter interlayer bonding between adjacent zones and reducing the size of the atomizing component; it also simplifies the processing technology and reduces manufacturing difficulty.

[0047] Reference Figure 7 and Figure 8 In one embodiment, the liquid storage area 210 is provided with at least one first liquid guiding hole 210c, and the diameter and / or number of holes of the first liquid guiding hole 210c on the first liquid storage area 210a is greater than the diameter and / or number of holes of the first liquid guiding hole 210c on the second liquid storage area 210b.

[0048] In this embodiment, the difference in pore density between the first liquid storage region 210a and the second liquid storage region 210b can be achieved by different numbers of first liquid guiding holes 210c on both regions, different pore diameters of the first liquid guiding holes 210c on both regions, or different numbers and diameters of the first liquid guiding holes 210c on both regions. It is understood that the change in pore density of the liquid storage region 210 can also be achieved during the manufacturing of the liquid storage region 210 by changing the raw material particle size or sintering aid ratio, or by adding composite filler materials. It can also be achieved by intervening in the molding process, by post-processing (such as chemical etching or dissolution pore-forming), or by directly stacking high-pore-density materials and low-pore-density materials alternately.

[0049] On the one hand, by using differences in pore size and / or number of pores to form a gradient structure, the design of large pore size and / or high number of pores in the liquid storage area 210 near the atomizing core 100 can effectively reduce the permeation resistance of the aerosol matrix and achieve rapid liquid conduction, thereby meeting the liquid supply requirements of the heating element 110; the design of small pore size and / or low number of pores in the liquid storage area 210 away from the atomizing core 100 can increase resistance through surface tension, thereby constraining the release rate of the aerosol matrix and thus avoiding local saturation of the heating element 110.

[0050] On the other hand, the pore density of the liquid storage zone 210 can be directly changed by the difference in pore size and / or pore number, without relying on the pore structure of the material itself, making the manufacturing process more flexible and helping to meet different usage requirements.

[0051] Reference Figure 9 In one embodiment, the first liquid guiding hole 210c extends along a first direction. In this embodiment, the extending direction of the first liquid guiding hole 210c is parallel to the first direction, and the first liquid guiding hole 210c is disposed on one of two end faces of the liquid storage structure 200 that are disposed opposite to each other along the first direction. It can be understood that the angle between the extending direction of the first liquid guiding hole 210c and the first direction can also be an acute angle.

[0052] The first liquid guiding hole 210c extends along the first direction, which not only works in conjunction with the multi-layer liquid storage area 210 to form a vertical conduction channel, increasing the rate at which the aerosol matrix is ​​transported to the heating element 110, but also shortens the straight-line transmission distance of the aerosol matrix from the outer layer of the liquid storage structure 200 to the heating element 110, reducing path resistance and improving the liquid supply response speed. In addition, it also reduces the manufacturing difficulty.

[0053] Reference Figure 8In one embodiment, the first liquid guiding hole 210c extends along the second direction. In this embodiment, the extending direction of the first liquid guiding hole 210c is parallel to the second direction. It is understood that the angle between the extending direction of the first liquid guiding hole 210c and the second direction can also be an acute angle.

[0054] The first liquid guiding hole 210c extends along the second direction, which not only enables the lateral conduction of the aerosol matrix within the same liquid storage area 210, balancing the liquid level difference in each circumferential region and avoiding local accumulation or shortage, but also, as the aerosol matrix flows through adjacent liquid storage areas 210, the gradient change in pore size and / or number of pores creates a pressure difference driving the aerosol matrix to overcome surface tension and permeate into the heating element 110.

[0055] Reference Figure 9 In one embodiment, the first liquid guiding hole 210c penetrates the liquid storage area 210. In this embodiment, the first liquid guiding hole 210c penetrates the liquid storage area 210 along a first direction or a second direction; it is understood that the first liquid guiding hole 210c may also be a blind hole extending along the first direction or the second direction.

[0056] The through-holes create a fully permeable path, reducing the transport resistance of the aerosol matrix and enabling it to quickly pass through the storage zone 210, effectively improving the conduction velocity of the aerosol matrix. Simultaneously, the through-holes allow for the removal of internal residues through backflushing and other methods, reducing cleaning difficulty.

[0057] Reference Figure 9 In one embodiment, a plurality of first liquid guiding holes 210c on the liquid storage area 210 are arranged along the circumference of the liquid storage area 210.

[0058] In this embodiment, a plurality of first liquid guiding holes 210c are uniformly arranged along the circumference of the liquid storage area 210; it can be understood that the spacing between any two adjacent first liquid guiding holes 210c in the three first liquid guiding holes 210c arranged in sequence may also be different.

[0059] The multiple circumferentially distributed first liquid guiding holes 210c not only enable the aerosol matrix to be synchronously conducted along the circumferential direction of the liquid storage area 210, avoiding local flow concentration and achieving uniform liquid guiding at 360°, thus reducing the risk of local dry burning of the heating element 110, but also prevent the aerosol matrix from being deflected due to the unidirectional distribution of the first liquid guiding holes 210c, thereby enhancing the stability of aerosol matrix transport.

[0060] Reference Figure 8In one embodiment, the first liquid guiding hole 210c extends circumferentially along the storage area 210. In this embodiment, the first liquid guiding hole 210c is an annular hole with both ends connected. In the above case, the storage area 210 may have only one first liquid guiding hole 210c. In this case, the diameter of the first liquid guiding hole 210c in the first storage area 210a is larger than the diameter of the first liquid guiding hole 210c in the second storage area 210b. The storage area 210 may also have multiple first liquid guiding holes 210c, and the diameters of the multiple first liquid guiding holes 210c are equal. In this case, the number of first liquid guiding holes 210c in the first storage area 210a is greater than the number of first liquid guiding holes 210c in the second storage area 210b.

[0061] The first liquid guiding hole 210c extends circumferentially along the liquid storage area 210, which not only connects different areas of the same liquid storage area 210, avoiding liquid level differences caused by local suction or uneven liquid storage, but also prevents leakage caused by dry burning or accumulation in a certain area due to a shortage of aerosol matrix. At the same time, it also enables the aerosol matrix to form a ring flow around the liquid storage area 210, ensuring that the amount of liquid received by each point around the heating element 110 is consistent, thus ensuring the consistency of the atomized taste.

[0062] Reference Figure 7 and Figure 8 In one embodiment, the diameters of any two first liquid guiding holes 210c are equal, and the number of first liquid guiding holes 210c on the first liquid storage region 210a is greater than the number of first liquid guiding holes 210c on the second liquid storage region 210b. It is understood that the number of first liquid guiding holes 210c on the first liquid storage region 210a can also be the same as the number of first liquid guiding holes 210c on the second liquid storage region 210b, while the diameter of the first liquid guiding holes 210c on the first liquid storage region 210a is greater than the diameter of the first liquid guiding holes 210c on the second liquid storage region 210b.

[0063] Uniform orifice diameter avoids stress concentration caused by differences in orifice diameter; at the same time, it can reduce mold specifications, reduce processing difficulty and cost, simplify processing technology, and improve processing efficiency. In addition, the gradient design of the number of orifices improves the liquid conduction efficiency through the porous design of the first liquid storage area 210a while ensuring the structural strength of the liquid storage area 210.

[0064] Reference Figures 3 to 5 as well as Figure 9In one embodiment, the atomizing core 100 includes an atomizing outer cover 120 arranged along a first direction, and a heating element 110 is disposed inside the atomizing outer cover 120. The outer surface of the atomizing outer cover 120 is provided with a liquid inlet hole 121 that connects the inside and outside of the atomizing outer cover 120. The liquid storage area 210 includes a plurality of liquid storage portions 211 arranged sequentially along the first direction. Among two adjacent liquid storage portions 211, the one closer to the liquid inlet hole 121 is the first liquid storage portion 211a, and the other farther away from the liquid inlet hole 121 is the second liquid storage portion 211b. The pore density of the first liquid storage portion 211a is higher than that of the second liquid storage portion 211b.

[0065] In this embodiment, the length direction of the atomizing cover 120 is parallel to the first direction, the heating element 110 is installed inside the atomizing cover 120, the extension direction of the liquid inlet hole 121 is parallel to the first direction, and the liquid inlet hole 121 is a through hole penetrating the atomizing cover 120. The liquid storage portion 211 has a ring-shaped or strip-shaped structure. Two adjacent liquid storage portions 211 in the same liquid storage area 210 have the same extension direction in the first direction, and any two liquid storage portions 211 in the same liquid storage area 210 are coaxially arranged. Furthermore, there are no gaps between adjacent liquid storage portions 211 in the same liquid storage area 210, and the multiple liquid storage portions 211 are integrally formed. It is understood that the multiple liquid storage portions 211 may not be arranged sequentially along the first direction, but rather irregularly. For example, a portion of the structure of the first liquid storage portion 211a may be inserted into the second liquid storage portion 211b. When the multiple liquid storage portions 211 are arranged sequentially along the first direction, the extension lengths of two adjacent liquid storage portions 211 in the first direction may also be different, and there may be gaps between adjacent liquid storage portions 211 in the same liquid storage area 210. Furthermore, the prefixes "first" and "second" preceding "liquid reservoir 211" are merely names; among multiple liquid reservoirs 211, the liquid reservoir 211 located between two liquid reservoirs 211 can be either the first liquid reservoir 211a or the second liquid reservoir 211b, depending on the comparison object, and is not specifically limited here.

[0066] Based on multiple liquid storage zones 210, the first liquid storage portion 211a near the liquid inlet 121 in this application adopts a high pore density design, while the second liquid storage portion 211b far from the liquid inlet 121 adopts a low pore density design. This structural design makes the liquid storage zone 210 form a gradient structure.

[0067] On the one hand, the first liquid storage section 211a with high porosity is closer to the liquid inlet 121, which has less resistance to the transmission of the aerosol matrix. This allows the aerosol matrix to quickly permeate towards the liquid inlet 121. This not only allows the aerosol matrix in the liquid storage area 210 to enter the atomizing cover 120 through the liquid inlet 121 and be atomized by the heating element 110, further reducing the residual amount of aerosol matrix in the liquid storage area 210, but also further ensures that there is sufficient aerosol matrix entering the atomizing cover 120 through the liquid inlet 121. This avoids the heating element 110 from dry burning due to delayed liquid supply, ensuring the atomized taste and extending the service life of the atomizing core 100.

[0068] On the other hand, the second liquid storage section 211b with low porosity is further away from the liquid inlet 121. It constrains the aerosol matrix from depositing too quickly downwards through surface tension, further reducing the amount of aerosol matrix remaining at the end of the liquid storage area 210.

[0069] On the other hand, multiple liquid storage sections 211 can simultaneously supply liquid to the area around the atomizing cover 120, so that the aerosol matrix is ​​evenly distributed around the atomizing cover 120, ensuring the stability of the atomized taste.

[0070] Reference Figure 9 In one embodiment, the liquid storage portion 211 is provided with at least one second liquid guiding hole 211c, and the diameter and / or number of holes of the second liquid guiding hole 211c on the first liquid storage portion 211a is greater than the diameter and / or number of holes of the second liquid guiding hole 211c on the second liquid storage portion 211b.

[0071] In this embodiment, the difference in pore density between the first liquid storage portion 211a and the second liquid storage portion 211b can be achieved by different numbers of second liquid guiding holes 211c on both, different pore diameters of the second liquid guiding holes 211c on both, or different numbers and diameters of the second liquid guiding holes 211c on both. It is understood that the change in pore density of the liquid storage portion 211 can also be achieved during the manufacturing of the liquid storage portion 211 by changing the raw material particle size or sintering aid ratio, or by adding composite filler materials. It can also be achieved by intervening in the molding process, by post-processing (such as chemical etching or dissolution pore-forming), or by directly stacking high-pore-density materials and low-pore-density materials alternately.

[0072] On the one hand, by using the difference in pore size and / or number of pores to form a gradient structure in the liquid storage area 210, the design of the large pore size and / or high number of pores in the liquid storage part 211 near the liquid inlet 121 can effectively reduce the permeation resistance of the aerosol matrix and achieve rapid liquid conduction, thereby meeting the liquid supply requirements of the heating element 110; the design of the small pore size and / or low number of pores in the liquid storage part 211 far from the liquid inlet 121 can constrain the aerosol matrix from depositing downwards too quickly through surface tension, further reducing the amount of aerosol matrix remaining at the end of the liquid storage area 210.

[0073] On the other hand, the pore density of the liquid storage part 211 can be directly changed by the difference in pore size and / or pore number, without relying on the pore structure of the material itself, making the manufacturing process more flexible and helping to meet different usage requirements.

[0074] In one embodiment, the second liquid guiding hole 211c extends along a first direction. In this embodiment, the extending direction of the second liquid guiding hole 211c is parallel to the first direction. It is understood that the angle between the extending direction of the second liquid guiding hole 211c and the first direction can also be an acute angle.

[0075] The second liquid guiding hole 211c extends along the first direction and is aligned with the direction of the liquid inlet hole 121, which shortens the conduction distance of the aerosol matrix from the liquid storage part 211 to the liquid inlet hole 121 and improves the liquid guiding efficiency.

[0076] In one embodiment, the second liquid guiding hole 211c extends along a second direction. In this embodiment, the extending direction of the second liquid guiding hole 211c is parallel to the second direction. It is understood that the angle between the extending direction of the second liquid guiding hole 211c and the second direction can also be an acute angle.

[0077] The second liquid guiding hole 211c extends along the second direction, which can not only balance the lateral liquid level difference of the liquid storage part 211 and prevent local aerosol matrix accumulation or shortage, but also disperse the stress concentration caused by the difference in pore size in the liquid storage part 211, and enhance the strength of the overall structure.

[0078] Reference Figure 9 In one embodiment, the second liquid guiding hole 211c penetrates the liquid storage portion 211. In this embodiment, the second liquid guiding hole 211c penetrates the liquid storage portion 211 along a first direction or a second direction; it is understood that the second liquid guiding hole 211c may also be a blind hole extending along the first direction or the second direction.

[0079] The through-holes create a fully permeable path, reducing the transport resistance of the aerosol matrix and enabling it to quickly pass through the liquid storage section 211, effectively improving the conduction speed of the aerosol matrix. Simultaneously, the through-holes allow for the removal of internal residues through methods such as backflushing, reducing cleaning difficulty.

[0080] Reference Figure 9 In one embodiment, a plurality of second liquid guiding holes 211c on the liquid storage portion 211 are arranged along the circumference of the liquid storage portion 211.

[0081] In this embodiment, a plurality of second liquid guiding holes 211c are uniformly arranged along the circumference of the liquid storage portion 211; it is understood that the spacing between any two adjacent second liquid guiding holes 211c in the three sequentially arranged second liquid guiding holes 211c may also be different.

[0082] The multiple circumferentially distributed second liquid guiding holes 211c not only enable the aerosol matrix to be synchronously conducted along the circumferential direction of the liquid storage part 211, avoiding local flow concentration and achieving uniform liquid guiding at 360°, thus reducing the risk of local dry burning of the heating element 110, but also prevent the aerosol matrix from being deflected due to the unidirectional distribution of the second liquid guiding holes 211c, thereby enhancing the stability of aerosol matrix transport.

[0083] Reference Figure 9 In one embodiment, the second liquid guiding hole 211c extends circumferentially along the liquid storage portion 211. In this embodiment, the second liquid guiding hole 211c is an annular hole with both ends connected. In the above case, the liquid storage portion 211 may be provided with only one second liquid guiding hole 211c. In this case, the diameter of the second liquid guiding hole 211c in the first liquid storage portion 211a is larger than the diameter of the second liquid guiding hole 211c in the second liquid storage portion 211b. The liquid storage portion 211 may also be provided with multiple second liquid guiding holes 211c, and the diameters of the multiple second liquid guiding holes 211c are equal. In this case, the number of second liquid guiding holes 211c in the first liquid storage portion 211a is greater than the number of second liquid guiding holes 211c in the second liquid storage portion 211b.

[0084] The second liquid guiding hole 211c extends circumferentially along the liquid storage section 211, which not only connects different areas of the same liquid storage section 211, avoiding liquid level differences caused by local suction or uneven liquid storage, but also prevents leakage caused by dry burning or accumulation in a certain area due to a shortage of aerosol matrix. At the same time, it also enables the aerosol matrix to form a ring flow around the liquid storage section 211, ensuring that the amount of liquid received by each point around the heating element 110 is consistent, thus ensuring the consistency of the atomized taste.

[0085] Reference Figure 9In one embodiment, the diameters of any two second liquid guiding holes 211c are equal, and the number of second liquid guiding holes 211c on the first liquid storage portion 211a is greater than the number of second liquid guiding holes 211c on the second liquid storage portion 211b. It is understood that the number of second liquid guiding holes 211c on the first liquid storage portion 211a can also be the same as the number of second liquid guiding holes 211c on the second liquid storage portion 211b, while the diameter of the second liquid guiding holes 211c on the first liquid storage portion 211a is greater than the diameter of the second liquid guiding holes 211c on the second liquid storage portion 211b.

[0086] Uniform orifice diameter avoids stress concentration caused by differences in orifice diameter; at the same time, it can reduce mold specifications, reduce processing difficulty and cost, simplify processing technology, and improve processing efficiency. In addition, the gradient design of the number of orifices improves the liquid conduction efficiency through the porous design of the first liquid storage part 211a while ensuring the structural strength of the liquid storage part 211.

[0087] Reference Figure 4 and Figure 5 In one embodiment, there are multiple liquid inlet holes 121, which are spaced apart circumferentially along the atomizing cover 120.

[0088] In this embodiment, there are four liquid inlet holes 121. It is understood that the number of liquid inlet holes 121 can also be other numbers, depending on the actual needs.

[0089] The circumferentially distributed liquid inlet holes 121 ensure uniform introduction of the aerosol matrix from the outer periphery of the atomizing cover 120, preventing localized oversaturation or uneven liquid supply to the heating element 110 caused by single-point liquid inlet, and ensuring uniform distribution of the aerosol matrix around the heating element 110. Simultaneously, multiple liquid inlet holes 121 introduce liquid at the same time, increasing the liquid guiding speed, reducing liquid supply lag, and lowering the risk of dry burning. Furthermore, if a single liquid inlet hole 121 becomes clogged with impurities, the other liquid inlet holes 121 can still maintain normal liquid intake, improving the anti-clogging capability and reliability of the atomizing core 100.

[0090] Reference Figure 3 as well as Figures 7 to 13 In one embodiment, the heating element 110 has an annular structure and a notch 111; the liquid storage portion 211 includes a plurality of liquid storage sections 2111 arranged sequentially along the circumference of the liquid storage portion 211, and one of two adjacent liquid storage sections 2111 is closer to the heating element 110 as the first liquid storage section 2111a, and the other is farther away from the heating element 110 as the second liquid storage section 2111b, and the pore density of the first liquid storage section 2111a is higher than that of the second liquid storage section 2111b.

[0091] In this embodiment, the heating element 110 and the liquid storage portion 211 are coaxially arranged, and the heating element 110 is mesh-shaped with an arc of less than 2π (i.e., a central angle of less than 360°). It can be understood that the heating element 110 and the liquid storage portion 211 may also be coaxially arranged. In a plurality of liquid storage sections 2111, the extension directions of two adjacent liquid storage sections 2111 in the circumferential direction of the liquid storage portion 211 are equal, and there are no gaps between two adjacent liquid storage sections 2111 in the same liquid storage portion 211. The plurality of liquid storage sections 2111 are integrally formed. It is understood that the plurality of liquid storage sections 2111 may not be arranged sequentially along the circumferential direction of the liquid storage portion 211, but may be arranged irregularly. For example, part of the structure of the first liquid storage section 2111a may be inserted into the second liquid storage section 2111b. When the plurality of liquid storage sections 2111 are arranged sequentially along the circumferential direction of the liquid storage portion 211, the extension lengths of two adjacent liquid storage sections 2111 in the circumferential direction of the liquid storage portion 211 may be different, and there may be gaps between two adjacent liquid storage sections 2111 in the same liquid storage portion 211. Furthermore, the prefixes "first" and "second" preceding "storage segment 2111" are merely names; among multiple storage segments 2111, the storage segment 2111 located between two storage segments 2111 can be either the first storage segment 2111 or the second storage segment 2111b, depending on the comparison object, and is not specifically limited here.

[0092] Based on multiple liquid storage sections 2111, the first liquid storage section 2111a near the heating element 110 in this application adopts a high pore density design, and the second liquid storage section 2111b far from the heating element 110 adopts a low pore density design. This structural design makes the liquid storage part 211 form a gradient structure.

[0093] On the one hand, the first liquid storage section 2111a with high porosity is closer to the heating element 110, and its transmission resistance to the aerosol matrix is ​​small, which promotes the rapid penetration of the aerosol matrix towards the heating element 110. This not only allows the aerosol matrix in the liquid storage area 210 to enter the atomizing cover 120 through the liquid inlet hole 121 and be atomized by the heating element 110, but also further reduces the residual amount of aerosol matrix in the liquid storage area 210. At the same time, it also further ensures that there is enough aerosol matrix entering the atomizing cover 120, improves the atomization efficiency, avoids the heating element 110 from dry burning due to liquid supply lag, ensures the atomized taste, and extends the service life of the atomizing core 100.

[0094] On the other hand, the second liquid storage section 2111b with low porosity is further away from the heating element 110. It uses surface tension to constrain the slow release of the aerosol matrix, thus avoiding the phenomenon of local saturation of the heating element 110 due to the aerosol matrix penetrating into the heating element 110 too quickly.

[0095] On the other hand, multiple liquid storage sections 2111 can simultaneously supply liquid to the area around the heating element 110, so that the aerosol matrix is ​​evenly distributed around the heating element 110, ensuring the stability of the atomized taste.

[0096] Reference Figure 7 , Figure 10 as well as Figure 11 In one embodiment, the liquid storage section 2111 is provided with at least one third liquid guiding hole 2111c, and the diameter and / or number of the third liquid guiding hole 2111c on the first liquid storage section 2111a is greater than the diameter and / or number of the third liquid guiding hole 2111c on the second liquid storage section 2111b.

[0097] In this embodiment, the difference in pore density between the first liquid storage section 2111a and the second liquid storage section 2111b can be achieved by different numbers of third liquid guiding holes 2111c on both sections, different pore diameters of the third liquid guiding holes 2111c on both sections, or different numbers and diameters of the third liquid guiding holes 2111c on both sections. It is understood that the change in pore density of the liquid storage section 2111 can also be achieved during the manufacturing of the liquid storage section 2111 by changing the raw material particle size or the proportion of sintering aids, or by adding composite filler materials. It can also be achieved by intervening in the molding process, by post-processing (such as chemical etching or dissolution pore-forming), or by directly stacking high-pore-density materials and low-pore-density materials alternately.

[0098] On the one hand, by using the difference in pore size and / or number of pores to form a gradient structure, the design of the large pore size and / or high number of pores in the liquid storage section 2111 close to the heating element 110 can effectively reduce the permeation resistance of the aerosol matrix and achieve rapid liquid conduction, thereby meeting the liquid supply requirements of the heating element 110; the design of the small pore size and / or low number of pores in the liquid storage section 2111 far from the heating element 110 can constrain the slow release of the aerosol matrix through surface tension, avoiding the phenomenon of local saturation of the heating element 110 due to the aerosol matrix permeating into the heating element 110 too quickly.

[0099] On the other hand, the pore density of the liquid storage section 2111 can be directly changed by the difference in pore size and / or pore number, without relying on the pore structure of the material itself, making the manufacturing process more flexible and helping to meet different usage requirements.

[0100] Reference Figure 7 , Figure 10 as well as Figure 11In one embodiment, the third liquid guiding hole 2111c extends along a first direction. In this embodiment, the extending direction of the third liquid guiding hole 2111c is parallel to the first direction. It is understood that the angle between the extending direction of the third liquid guiding hole 2111c and the first direction can also be an acute angle.

[0101] The third liquid guiding hole 2111c extends along the first direction and is aligned with the length direction of the heating element 110. This shortens the straight-line transmission distance of the aerosol matrix from the liquid storage section 2111 to the heating element 110, reduces path resistance, and improves the liquid supply response speed. In addition, it also reduces manufacturing difficulty.

[0102] In one embodiment, the third liquid guiding hole 2111c extends along the second direction. In this embodiment, the extending direction of the third liquid guiding hole 2111c is parallel to the second direction. It is understood that the angle between the extending direction of the third liquid guiding hole 2111c and the second direction can also be an acute angle.

[0103] The third liquid guiding hole 2111c extends along the second direction, which can not only balance the lateral liquid level difference of the liquid storage section 2111 and prevent local aerosol matrix accumulation or shortage, but also disperse the stress concentration caused by the difference in pore size in the liquid storage section 2111, and enhance the strength of the overall structure.

[0104] Reference Figure 7 , Figure 10 as well as Figure 11 In one embodiment, the third liquid guiding hole 2111c penetrates the liquid storage section 2111. In this embodiment, the third liquid guiding hole 2111c penetrates the liquid storage section 2111 along a first direction or a second direction; it is understood that the third liquid guiding hole 2111c may also be a blind hole extending along the first direction or the second direction.

[0105] The through-holes create a fully permeable path, reducing the transport resistance of the aerosol matrix and enabling it to quickly pass through the liquid storage section 2111, effectively improving the conduction speed of the aerosol matrix. Simultaneously, the through-holes allow for the removal of internal residues through backflushing and other methods, reducing cleaning difficulty.

[0106] Reference Figure 7 , Figure 10 as well as Figure 11 In one embodiment, a plurality of third liquid guiding holes 2111c on the liquid storage section 2111 are arranged along the circumference of the liquid storage section 2111.

[0107] In this embodiment, a plurality of third liquid guiding holes 2111c are uniformly arranged along the circumference of the liquid storage section 2111; it can be understood that the spacing between any two adjacent third liquid guiding holes 2111c in the three third liquid guiding holes 2111c arranged in sequence may also be different.

[0108] The multiple circumferentially distributed third liquid guiding holes 2111c not only enable the aerosol matrix to be synchronously conducted along the circumferential direction of the liquid storage section 2111, avoiding local flow concentration and achieving 360° uniform liquid guiding, thus reducing the risk of local dry burning of the heating element 110, but also prevent the aerosol matrix from being deflected due to the unidirectional distribution of the third liquid guiding holes 2111c, thereby enhancing the stability of aerosol matrix transport.

[0109] In one embodiment, the third liquid guiding hole 2111c extends circumferentially along the liquid storage section 2111. In this embodiment, the third liquid guiding hole 2111c is an arc-shaped hole. In the above case, the liquid storage section 2111 may be provided with only one third liquid guiding hole 2111c. In this case, the diameter of the third liquid guiding hole 2111c of the first liquid storage section 2111a is larger than the diameter of the third liquid guiding hole 2111c of the second liquid storage section 2111b. The liquid storage section 2111 may also be provided with multiple third liquid guiding holes 2111c, and the diameters of the multiple third liquid guiding holes 2111c are equal. In this case, the number of third liquid guiding holes 2111c of the first liquid storage section 2111a is greater than the number of third liquid guiding holes 2111c of the second liquid storage section 2111b.

[0110] The third liquid guiding hole 2111c extends circumferentially along the liquid storage section 2111, which not only connects different areas of the same liquid storage section 2111, avoiding liquid level differences caused by local suction or uneven liquid storage, but also prevents leakage caused by dry burning or accumulation in a certain area due to a shortage of aerosol matrix. At the same time, it also enables the aerosol matrix to form a ring flow around the liquid storage section 211, ensuring that the amount of liquid received by each point around the heating element 110 is consistent, thus ensuring the consistency of the atomized taste.

[0111] Reference Figure 7 , Figure 10 as well as Figure 11 In one embodiment, the diameters of any two third liquid guiding holes 2111c are equal, and the number of third liquid guiding holes 2111c on the first liquid storage section 2111a is greater than the number of third liquid guiding holes 2111c on the second liquid storage section 2111b. It is understood that the number of third liquid guiding holes 2111c on the first liquid storage section 2111a can also be the same as the number of third liquid guiding holes 2111c on the second liquid storage section 2111b, while the diameter of the third liquid guiding holes 2111c on the first liquid storage section 2111a is greater than the diameter of the third liquid guiding holes 2111c on the second liquid storage section 2111b.

[0112] Uniform orifice diameter avoids stress concentration caused by differences in orifice diameter; at the same time, it can reduce mold specifications, reduce processing difficulty and cost, simplify processing technology, and improve processing efficiency. In addition, the gradient design of the number of orifices improves the liquid guiding efficiency through the multi-hole design of the first liquid storage section 2111a while ensuring the structural strength of the liquid storage section 2111.

[0113] Reference Figures 8 to 10 In one specific embodiment, the liquid storage structure 200 includes a plurality of liquid storage areas 210 uniformly arranged along a second direction, which is perpendicular to the first direction. A first liquid guiding hole 210c penetrates the liquid storage area 210 along the first direction, and any two first liquid guiding holes 210c have the same diameter. The liquid storage area 210 includes a plurality of liquid storage portions 211 uniformly arranged along the first direction. A second liquid guiding hole 211c is an annular hole extending circumferentially along the liquid storage portion 211, communicating with the first liquid guiding hole 210c, and any two second liquid guiding holes 211c have the same diameter. The liquid storage portion 211 includes a plurality of liquid storage segments 2111 uniformly arranged circumferentially along the liquid storage portion 211, and a third liquid guiding hole 2111c is the first liquid guiding hole 210c.

[0114] It is understood that the liquid storage structure 200 may only include multiple liquid storage areas 210 uniformly arranged along the second direction, and the liquid storage areas 210 are no longer divided into multiple liquid storage parts 211. In one case, the second direction is parallel to the first direction, in which case the one of two adjacent liquid storage areas 210 closer to the liquid inlet 121 is the first liquid storage area 210a, and the one farther away from the liquid inlet 121 is the second liquid storage area 210b. In another case, the second direction is perpendicular to the first direction, in which case the one of two adjacent liquid storage areas 210 closer to the atomizing cover 120 is the first liquid storage area 210a, and the one farther away from the atomizing cover 120 is the second liquid storage area 210b. In yet another case, the second direction is the circumferential direction of the liquid storage structure 200, in which case the one of two adjacent liquid storage areas 210 closer to the heating element 110 is the first liquid storage area 210a, and the one farther away from the heating element 110 is the second liquid storage area 210b.

[0115] In the three cases described above, the first liquid guiding hole 210c can extend along the first direction, the second direction, or the circumference of the liquid storage area 210. Furthermore, the liquid storage area 210 can also be provided with liquid guiding holes whose extension direction is different from that of the first liquid guiding hole 210c. These will not be listed individually here, as long as they ensure rapid penetration of the aerosol matrix into the heating element 110.

[0116] It is understood that the liquid storage area 210 may include a plurality of liquid storage portions 211 uniformly arranged along the first direction, and the liquid storage portions 211 are no longer divided into multiple liquid storage segments 2111; in this case, the second liquid guiding hole 211c may extend along the first direction, or along the second direction, or along the circumference of the liquid storage portion 211.

[0117] It is understood that the liquid storage portion 211 may include a plurality of liquid storage sections 2111 uniformly arranged circumferentially along the liquid storage portion 211. In this case, the third liquid guiding hole 2111c may extend along the first direction, or along the second direction, or along the circumferential direction of the liquid storage section 2111.

[0118] Furthermore, the extension directions of the first liquid guiding hole 210c, the second liquid guiding hole 211c, and the third liquid guiding hole 2111c can be parallel, collinear, or perpendicular to each other; at the same time, the first liquid guiding hole 210c, the second liquid guiding hole 211c, and the third liquid guiding hole 2111c can be the same hole.

[0119] Reference Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 11 as well as Figure 13 In one embodiment, the atomizing core 100 further includes a liquid-guiding cotton 130, which is disposed inside the atomizing cover 120 along a first direction and wraps around the heating element 110; the liquid-guiding cotton 130 has a protruding portion 131 that protrudes outward toward the outside of the atomizing cover 120, the protruding portion 131 covers the notch 111 and contacts the liquid storage structure 200.

[0120] In this embodiment, the length direction of the liquid-guiding cotton 130 is parallel to the first direction and wraps and fixes the heating element 110; the protruding part 131 is a cotton-cutting opening, which completely covers the notch 111 and is in interference contact with the liquid storage structure 200.

[0121] The liquid-guiding cotton 130 is in direct contact with the liquid storage structure 200 through its protruding portion 131, which shortens the transmission path of the aerosol matrix and improves transmission efficiency and speed. In addition, the atomizing assembly also includes a liquid storage cup 300, and the liquid-guiding cotton 130 and the atomizing core 100 are all disposed within the liquid storage cup 300.

[0122] Reference Figures 1 to 13 According to another aspect of this application, embodiments of this application also provide an atomizing device, which further includes an atomizing shell 400, a power supply component 1000 and the aforementioned atomizing component. The atomizing core 100, the liquid storage structure 200 and the power supply component 1000 are disposed within the atomizing shell 400, and the power supply component 1000 is electrically connected to the atomizing component.

[0123] In this embodiment, the length direction of the atomizing shell 400 is parallel to the first direction. Furthermore, a nozzle 500 is provided on the atomizing shell 400, and the nozzle 500 communicates with the interior of the atomizing shell 400. The atomizing device also includes a fiberglass tube 600, an upper sealing silicone, an upper absorbent cotton 700, a lower sealing silicone 800, and an atomizing base 900; the fiberglass tube 600 is disposed on the atomizing core 100, and the atomizing channel in the atomizing core 100 is connected to the nozzle 500 through the fiberglass tube 600; the upper sealing silicone is disposed inside the atomizing shell 400 and located between the atomizing component and the nozzle 500, and the upper absorbent cotton 700 is disposed on the surface of the upper sealing silicone near the nozzle 500; the lower sealing silicone 800 is disposed inside the atomizing shell 400 and located on the side of the atomizing component away from the nozzle 500, and the atomizing base 900 is disposed on the lower sealing silicone 800 for supporting the atomizing component.

[0124] In summary, implementing the atomizing component and atomizing device provided in this embodiment has at least the following beneficial technical effects: In this application, the first liquid storage area 210a near the heating element 110 adopts a high pore density design, and the second liquid storage area 210b far from the heating element 110 adopts a low pore density design. This structural design makes the liquid storage structure 200 form a gradient structure.

[0125] On the one hand, the high-porosity first liquid storage zone 210a is closer to the heating element 110, resulting in lower resistance to aerosol matrix transmission. This facilitates rapid penetration of the aerosol matrix into the heating element 110 of the atomizing core 100. This not only allows the aerosol matrix within the liquid storage structure 200 to fully penetrate into the atomizing core 100 and be atomized by the heating element 110, reducing residual aerosol matrix within the liquid storage structure 200, but also ensures sufficient aerosol matrix around the atomizing core 100, preventing dry burning of the heating element 110 due to delayed liquid supply, thus ensuring optimal atomized flavor and extending the lifespan of the atomizing core 100. Furthermore, the rapid oil-conducting characteristics of the high-porosity first liquid storage zone 210a allow the aerosol matrix to penetrate more quickly to the vicinity of the atomizing core 100 after initial use or prolonged resting, reducing dry suction and improving start-up response speed.

[0126] On the other hand, the second liquid storage region 210b with low porosity is further away from the heating element 110. It constrains the slow release of the aerosol matrix through surface tension, preventing local saturation of the heating element 110 due to excessively rapid permeation of the aerosol matrix. Simultaneously, the lower porosity of the second liquid storage region 210b enhances capillary action, enabling unidirectional transport of the aerosol matrix towards the heating element 110 and suppressing backflow of the aerosol matrix caused by pressure changes or tilting.

[0127] On the other hand, the gradient transmission of the liquid storage structure 200 avoids local accumulation or shortage of aerosol matrix in the liquid storage structure 200, which not only makes the distribution of aerosol matrix around the atomizing core 100 more uniform, but also improves the consistency of aerosol concentration generated during atomization and improves the stability of taste when the user inhales.

[0128] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
