Description

Technical Field

[0001] The present application relates to the technical field of atomization devices, and more particularly, to a convex multi-porous carbon atomization core and an electronic atomizer. Background Art

[0002] The atomization core is the core component of an electronic atomizer. Currently, the commonly used atomization cores in the market are multi-porous ceramic atomization cores and cotton cores. The multi-porous ceramic atomization core uses printing a metal thick film or inlaying a metal heating wire on the multi-porous ceramic as the heating element, which has problems such as a small atomization area, easy carbon accumulation and pore blockage, and easy peeling of the metal film or metal wire from the multi-porous ceramic. The cotton core uses a metal wire or metal mesh as the heating element, and conducts the e-liquid to the surface of the metal wire or metal mesh through the wicking cotton to achieve heating and atomization. Since the heating element is in direct contact with the wicking cotton, there is a problem of burning the cotton and clogging the core. At the same time, whether it is a ceramic atomization core or a cotton core, a metal material is used as the heating element, and the metal heating element is prone to metal ion release. The catalytic effect of the metal may also lead to an increase in harmful products, which is not conducive to harm reduction and produces strange tastes.

[0003] The multi-porous carbon atomization core overcomes the above disadvantages. The heating element of the multi-porous carbon atomization core is itself multi-porous carbon, which has a large atomization area and is not easy to accumulate carbon and block pores. The heating element of the multi-porous carbon atomization core and the multi-porous carbon matrix are of an integral structure, there is no interface, and it will not peel off. The multi-porous carbon itself has an oil-conducting function, and the heating element does not contact the cotton, so there is no problem of burning the cotton and clogging the core. The multi-porous carbon atomization core uses a carbon material as the heating element, without metal ion release, and there is no catalytic effect of the metal, which can reduce the release of harmful substances and improve the taste quality.

[0004] The porous carbon atomizing core is a new type of atomizing core under development and is not yet in use. Its structure and function are significantly different from those of ceramic cores and cotton cores, and it has many unknown characteristics. It is still in the process of being understood and explored. As the understanding of the porous carbon atomizing core deepens, its performance will be continuously optimized and improved, further promoting its application process. Practice has shown that for the porous carbon atomizing core, the setting method of the heating element has a huge impact on its overall performance. Previous patents have disclosed porous carbon atomizing cores with three heating element structures. One is the body heating type (CN219699047U), and this structure has problems such as serious heat consumption, low heating efficiency, and overheating of e-liquid. The second is the embedded structure (CN220423126U), where the heating element is arranged on the side wall of the groove that penetrates deep into the porous carbon and is perpendicular to the smoke outlet surface. There are problems such as poor smoke outlet and the inability to discharge smoke in a timely manner, and the amount of smoke is small. The third is that the heating element is arranged parallel to the surface of the porous carbon (CN220423126U), which is a uniform and continuous surface heating element. This structure has a better effect, smooth smoke outlet, and an increase in the amount of smoke, but the increase is not large enough, and the natural advantages of the porous carbon material are not fully utilized, and there is still much room for improvement. The heating element of the porous carbon atomizing core itself is also a porous structure, and it has the advantages of convenient setting of the heating element structure and the ability to make complex structures. According to the characteristics of the porous carbon material and the basic principle of atomization, further optimizing the heating element structure is of great significance for obtaining a porous carbon atomizing core with excellent performance. Summary of the Invention

[0005] An object of an embodiment of the present application is to provide a convex-platform type porous carbon atomizing core and an electronic atomizer, which can improve the atomization performance of the electronic atomizer.

[0006] In a first aspect, an embodiment of the present application provides a convex-platform type porous carbon atomizing core. The convex-platform type porous carbon atomizing core is integrally formed with porous carbon. The convex-platform type porous carbon atomizing core includes a base portion, a convex platform portion, a recessed portion, and an electrode portion. The convex platform portion is connected to the base portion, and the conductivity of the convex platform portion is higher than that of the base portion, so that the convex platform portion can concentrate current to form a heating element, and the electrode portion is connected to the convex platform portion.

[0007] In the above implementation process, the matrix part in the convex platform type porous carbon atomization core of the present application has low electrical conductivity and thermal conductivity, and it does not serve as a heat - generating atomization area, but only plays the functions of liquid absorption, liquid conduction, and heat insulation. The convex platform part has high electrical conductivity, so that the convex platform part can concentrate current to form a heating element. The present application optimizes the structure of the heating element to improve the performance of the atomization core. Among them, the convex platform part can increase the lateral smoke - emitting surface, thereby increasing the atomization area; the concave area is adjacent to the heating element, and its existence increases the oil - guiding channels owned by the heating element. At the same time, it can store the liquid derived from the porous structure. Under the action of surface tension, the atomized matter can quickly spread along the side surface of the convex platform part to the top of the convex platform part, promoting oil conduction. The concave area can also adjust the area of the convex platform, thereby adjusting the resistance and power density of the heating element, separating the temperature field, reducing heat diffusion, concentrating heat to improve the heating efficiency, and thus improving the atomization performance of the electronic atomizer.

[0008] In a possible implementation, the convex platform part includes at least one convex platform.

[0009] In a possible implementation, the concave part includes at least one concave area to form convex platforms, and the convex platforms and the concave areas are alternately distributed.

[0010] In the above implementation process, the convex platform part can increase the lateral smoke - emitting surface, thereby increasing the atomization area; the concave area is adjacent to the heating element, and the oil - guiding channels in the porous carbon below it can supply oil to the heating element adjacent to the convex platform. Its existence increases the oil - guiding channels owned by the heating element. At the same time, it can store the liquid derived from the porous structure. Under the action of surface tension, the atomized matter can quickly spread along the side surface of the convex platform part to the top, promoting oil conduction. The concave area can also adjust the area of the convex platform part, thereby adjusting the resistance and power density, separating the temperature field, reducing heat diffusion, concentrating heat to improve the heating efficiency, and thus improving the atomization performance of the electronic atomizer.

[0011] In a possible implementation, the height of the convex platform and the depth of the concave area are both 0.1 mm to 1 mm.

[0012] In the above implementation process, by making the depth of the concave area 0.1 mm to 1 mm, not only can the atomization area be enlarged, but also oil conduction can be promoted, heat capacity can be reduced, and heat diffusion can be decreased. If the depth is too small, the above - mentioned beneficial effects cannot be fully exerted. If the depth is too large, the liquid stored in the concave area is too far from the atomization surface at the top of the convex platform part, which not only cannot further promote oil conduction, but also reduces the strength of the atomization core.

[0013] In a possible implementation, the width of the convex platform is 0.1 mm to 5 mm, and the width of the concave area is 0.1 mm to 3 mm.

[0014] In the above implementation process, the width of the concave area is 0.1mm to 3mm, which can achieve the purpose of expanding the atomization area, promoting oil conduction, reducing heat capacity, and reducing heat diffusion. If the width is too small, the above beneficial effects cannot be fully exerted. If the width is too large, the liquid stored in the concave area is too far away from the boss part, which cannot further promote oil conduction and will increase the volume of the atomizer core, which is not conducive to miniaturization. At the same time, it increases heat capacity and leads to increased heat consumption.

[0015] In a possible embodiment, the boss-type porous carbon atomization core has an oil absorption surface for contacting the atomized material.

[0016] In a possible implementation, the boss-type porous carbon atomization core has a smoke outlet surface for releasing smoke, and the surface of the boss-type porous carbon atomization core where the bosses are located forms the smoke outlet surface, and the smoke outlet surface and the oil absorption surface are in relative positions.

[0017] In the above implementation process, the surface of the boss-type porous carbon atomizer core where the boss portion is located is the smoke outlet surface, and the smoke generated by atomization is guided out from the smoke outlet surface. The surface of the atomizer core opposite to the smoke outlet surface is the oil absorption surface, and the atomizer enters the atomizer core from the oil absorption surface and is conducted to the boss portion. By arranging the oil absorption surface and the smoke outlet surface opposite to each other, the oil guide path can be shortened, thereby increasing the liquid guide rate of the boss-type porous carbon atomizer core, and further improving the atomization effect of the atomizer.

[0018] In a possible implementation manner, the electrode portion includes two electrodes, a portion between the two electrodes on the same boss forms an atomization zone, and a surface of the atomization zone forms an atomization surface.

[0019] In a second aspect, an embodiment of the present application provides an electronic atomizer, which includes the boss-type porous carbon atomization core in the above embodiment.

[0020] In the above implementation process, the electronic atomizer of the present application has good atomization performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Please refer to Figures 1 - 3 , the present application provides a convex platform type porous carbon atomization core 100. The convex platform type porous carbon atomization core 100 is integrally formed by porous carbon. The convex platform type porous carbon atomization core 100 includes a base part 110, a convex platform part 120, a concave part 140 and an electrode part 130. The convex platform part 120 includes at least one convex platform. The concave part 140 includes at least one concave area. The convex platform part 120 is connected to the base part 110. At least one side of the convex platform is provided with a concave area to form the convex platform. The conductivity of the convex platform part 120 is higher than that of the base part 110, so that the atomization part can concentrate the current to form a heating element, and the electrode part 130 is connected to the convex platform part 120.

[0065] Optionally, the carbon content of the convex platform type porous carbon atomization core 100 is not less than 60%.

[0066] Optionally, the porosity of the convex platform type porous carbon atomization core 100 is 10% - 90%.

[0067] The porous structures of the base part 110 and the convex platform part 120 can endow it with good liquid absorption and liquid conduction capabilities, and at the same time have appropriate mechanical strength. The porous structure of the convex platform part 120 can ensure that the atomized substances therein are fully heated and atomized, improving the atomized smoke volume.

[0068] In some embodiments, the shape of the convex platform type porous carbon atomization core 100 includes a cuboid, a cube, a polyhedron, a cylinder or a hollow tube.

[0069] Optionally, the shape of the convex platform type porous carbon atomization core 100 is a cuboid or a hollow tube.

[0070] It should be noted that the shape of the convex platform porous carbon atomizing core 100 is not necessarily a strictly rectangular parallelepiped, cube, polyhedron, cylinder or hollow tube, but can be formed by machining or laser processing of a rectangular parallelepiped, cube, polyhedron, cylinder or hollow tube.

[0071] In some embodiments, the shape of the base portion 110 includes a rectangular parallelepiped, cube, polyhedron, cylinder or hollow tube.

[0072] Optionally, the shape of the base portion 110 is a rectangular parallelepiped or a hollow tube.

[0073] In some embodiments, the shape of the convex platform portion 120 includes a rectangular parallelepiped, cube, polyhedron, curved body or a combination thereof.

[0074] Optionally, the shape of the convex platform portion 120 is a rectangular parallelepiped or a curved body.

[0075] The convex platform portion 120 can be formed by machining or laser processing of porous carbon. The unprocessed part at the bottom is the base portion 110, and the processed part at the top is the convex platform portion 120. The space left after processing is the recessed area.

[0076] In some embodiments, the electrode portions 130 are disposed at both ends of the convex platform portion 120, and the electrode portions 130 are used to connect to an external circuit.

[0077] In some embodiments, the convex platform porous carbon atomizing core 100 includes one convex platform and two recessed areas, and the recessed areas are located on both sides of the convex platform portion 120.

[0078] The recessed area is adjacent to the heating element. The oil guiding channels in the porous carbon below it can supply oil to the heating element near the convex platform. Its existence increases the oil guiding channels owned by the heating element, and at the same time can store the liquid derived from the porous structure. Under the action of surface tension, the atomized matter can quickly diffuse along the side surface of the convex platform portion 120 to the atomizing portion to promote oil guiding. The recessed area can also adjust the area of the convex platform so as to adjust its resistance and power density, and separate the temperature field, reduce heat diffusion, concentrate heat to improve the heating efficiency, and thus improve the atomizing performance of the electronic atomizer 10.

[0079] In some embodiments, the convex platform porous carbon atomizing core 100 includes at least two convex platform portions 120 and at least one recessed area, and the convex platform portions 120 and the recessed areas are alternately distributed.

[0080] The boss portion 120 can increase the lateral atomization surface 123, thereby increasing the atomization area; the recessed area is adjacent to the heating element, and the oil guiding channels in the porous carbon below it can supply oil to the boss heating element in the vicinity. Its presence increases the oil guiding channels owned by the heating element, and at the same time can store the liquid derived from the porous structure. Under the action of surface tension, the atomized matter can quickly spread along the side of the boss to the top, promoting oil guiding. The recessed area can also adjust the area of the boss portion 120 so as to adjust its resistance and power density, and separate the temperature field, reduce heat diffusion, concentrate heat and improve the heating efficiency, thereby improving the atomization performance of the electronic atomizer 10.

[0081] In some embodiments, the width of the boss is 0.5 mm to 5 mm.

[0082] It should be noted that the width of the boss can be flexibly adjusted, so as to adjust the area and resistance value of the heating and atomization area 121, so that the atomization core can be applied to different types of electronic atomizers 10.

[0083] In some embodiments, the depth of the recessed area is 0.1 mm to 1 mm.

[0084] As an example, the depth of the recessed area can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm.

[0085] By making the depth of the recessed area 0.1 mm to 1 mm, not only can the atomization area be expanded, but also the oil guiding can be promoted, the heat capacity can be reduced, and the heat diffusion can be reduced. If the depth is too small, the above beneficial effects cannot be fully exerted. If the depth is too large, the liquid stored in the recessed area is too far from the atomization surface 122 at the top of the boss portion 120, which not only cannot further promote the oil guiding, but also reduces the strength of the atomization core.

[0086] In some embodiments, the width of the recessed area is 0.1 mm to 3 mm.

[0087] It should be noted that the width of the recessed area refers to the distance between two adjacent sides of two adjacent bosses or the distance between the side of the boss adjacent to the edge of the atomization core and the edge of the atomization core.

[0088] As an example, the width of the recessed area can be 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm.

[0089] By making the width of the recessed area 0.1 mm to 3 mm, the purposes of expanding the atomization area, promoting oil conduction, reducing the heat capacity, and reducing heat diffusion can be achieved. If the width is too small, the above beneficial effects cannot be fully exerted. If the width is too large, the liquid stored in the recessed area is too far from the boss portion 120, which cannot further promote oil conduction, and will also increase the volume of the atomization core, which is not conducive to miniaturization. At the same time, it increases the heat capacity, resulting in an increase in heat consumption.

[0090] In some embodiments, the base portion 110 has a smoke outlet surface 112 for releasing smoke and an oil absorption surface 111 in contact with the atomized substance. The oil absorption surface 111 and the smoke outlet surface 112 are oppositely arranged; the smoke outlet surface 112 is the surface of the boss-shaped porous carbon atomization core 100 where the boss heating element is located.

[0091] By arranging the smoke outlet surface 112 and the oil absorption surface 111 oppositely, the liquid conduction distance can be shortened, thereby improving the liquid conduction rate of the atomization core, and further improving the atomization effect of the electronic atomizer.

[0092] In some embodiments, the shape of the boss-shaped porous carbon atomization core 100 is a cuboid. The cuboid has two opposite surfaces, one of which is the oil absorption surface 111 and the other is the smoke outlet surface 112.

[0093] In some embodiments, the shape of the boss-shaped porous carbon atomization core 100 is a hollow tube. The atomization core includes an inner surface and an outer surface, and one of the inner surface and the outer surface is the oil absorption surface 111 and the other is the smoke outlet surface 112.

[0094] The base portion 110 in the boss-shaped porous carbon atomization core 100 of the present application has low electrical conductivity and thermal conductivity. It does not serve as a heating and atomizing area, but only plays the functions of liquid absorption, liquid conduction, and heat insulation. The boss portion 120 has high electrical conductivity so that it can concentrate current to form a heating element. The present application improves its performance by optimizing the structure of the atomization core. Among them, the boss portion 120 can increase the lateral atomization surface 123, thereby realizing an increase in the atomization area; the recessed area is adjacent to the heating element, and the oil conduction channels in the porous carbon below it can supply oil to the boss heating element in the vicinity. Its existence increases the oil conduction channels owned by the heating element, and at the same time can store the liquid exported by the porous carbon. Under the action of surface tension, the atomized substance can quickly diffuse along the side surface of the boss portion 120 to the top of the boss portion 120, promoting oil conduction. The recessed area can also adjust the area of the boss portion 120 to adjust the resistance and power density, and separate the temperature field, reduce heat diffusion, concentrate heat, and improve the heating efficiency, thereby improving the atomization performance of the electronic atomizer 10.

[0095] Among them, the convex platform and the concave structure have the following beneficial effects: (1) increasing the side atomization surface, thereby increasing the atomization area; (2) the concave area is adjacent to the convex platform heating element, and the porous carbon oil guiding channel below it can be utilized by the adjacent heating element, and its existence increases the oil guiding channels owned by the heating element; (3) the concave area can store the liquid derived from the porous structure. Under the action of surface tension, the atomized matter can quickly diffuse along the side surface of the convex platform portion 120 to the top atomization surface 122 of the convex platform portion 120, promoting oil guiding; (4) the concave area can adjust the area of the convex platform so as to adjust the resistance and power density; (5) separating the temperature field, reducing heat diffusion, concentrating heat to improve the heating efficiency, and further improving the atomization performance of the electronic atomizer 10.

[0096] The convex platform type porous carbon atomization core 100 of the present application can be prepared by the following method:

[0097] S1. Prepare porous carbon

[0098] Mix the carbon source precursor and the pore-forming agent, and then carry out solidification and carbonization treatment. During the process, the pore-forming agent is removed by dissolution washing or heating decomposition method to obtain a porous carbon blank.

[0099] S2. Process

[0100] Use methods such as mechanical processing and laser processing to form a convex platform structure and a concave area on the surface of the porous carbon blank.

[0101] Carry out carbonization or graphitization of the convex platform at a higher temperature through surface heat treatment or surface laser treatment, so that the resistivity of the convex platform portion 120 drops significantly to form a heating element.

[0102] Among them, the resistivity of the convex platform portion 120 is significantly reduced by surface heat treatment or surface laser treatment. This process does not change the structural form, still maintains the integration of the liquid absorption and liquid guiding part and the convex platform heating element, and keeps the convex platform heating element still in a porous structure. Therefore, the liquid absorption and liquid guiding channels of the heating element part can be ensured to be unobstructed, thereby greatly increasing the atomization channels and atomization area.

[0103] S3. Make electrodes

[0104] Use methods such as screen printing, pad printing, dispensing, brushing, coating, bonding, and welding to make electrodes on the surface of the convex platform portion 120.

[0105] The present application also provides an electronic atomizer 10, which includes the convex platform type porous carbon atomization core 100 in the above embodiment.

[0106] The electronic atomizer 10 of the present application has good atomization performance.
