Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ceramic atomizing cores, in particular to a novel porous film ceramic atomizing core nested structure. Background Art
[0002] At present, the e-cigarette market is basically dominated by cotton mesh core structure atomizer cores, thick film atomizer cores or embedded atomizer cores. The atomization principle is that the tiny metal circuit (achieved by etching, stamping or printing processes) is resistively heated after the current flows, so that the smoke liquid is atomized. This working mode will make the temperature around the circuit too high and the temperature of the ceramic surface too low, which will cause uneven temperature distribution on the entire atomization surface, poor taste, and even excessive aldehydes. Therefore, a new type of porous film ceramic atomizer core embedded structure is needed.
[0003] In the existing technology, when the oil-conducting ceramic atomizer core is idle, the sealing cover can be rotated so that the sealing ring is nested in the mouthpiece tube inside the cigarette tube, blocking the mouthpiece tube to prevent external dust or dirt from entering the mouthpiece. However, there is insufficient oil supply capacity, resulting in the inability to meet the atomization needs of large-capacity and high-power electronic cigarettes. Utility Model Content

[0022] 2. In the present invention, the roughness of the surface of the porous ceramic body is reduced by the thin film coating transition layer, so that the thin film heating layer has good continuity, which is convenient for adjusting and controlling the thickness of the thin film heating layer. The thin film coating transition layer can also block the sodium and potassium ions of the porous ceramic body from diffusing into the thin film heating layer under the action of the electric field, thereby enhancing the stability of the resistance of the thin film heating layer. In addition, the thin film coating transition layer can adjust the stress matching between the thin film heating layer and the surface of the porous ceramic body, enhance the adhesion between the thin film heating layer and the porous ceramic body, so that the thin film heating layer is firmly bonded to the porous ceramic body, thereby improving the stability and reliability of the working performance of the thin film heating layer and extending the service life of the atomization core.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a novel porous film ceramic atomization core nested structure, including a porous ceramic base 1, the porous ceramic base 1 has mounting holes 3 on both sides of the upper left and right sides, and the porous ceramic base 1 has a mounting slot 2 on the middle part, through which the smoke oil can be stored, and a ceramic atomization chip assembly is arranged inside the mounting slot 2 to meet the atomization requirements of large-capacity and high-power electronic cigarettes. The ceramic atomization chip assembly includes a porous film ceramic atomization chip 5, which is fixedly connected to the inside of the mounting slot 2. The porous film ceramic atomization chip 5 is installed through the mounting slot 2 to improve the oil delivery efficiency. Rate, ejector pin contact springs 4 are provided on both sides of the upper left and right sides of the porous film ceramic atomization chip 5, the porous film ceramic atomization chip 5 includes a porous ceramic body 6, the upper part of the porous ceramic body 6 is fixedly connected with a thin film coating transition layer 7, the upper part of the thin film coating transition layer 7 is fixedly connected with a thin film heating layer 8, and the lower part of the two ejector pin contact springs 4 away from each other is provided with a protrusion, the protrusion is slidably connected to the inside of the mounting hole 3, and the ejector pin contact spring 4 is installed through the protrusion and the mounting hole 3. When the assembled ceramic atomization core is assembled to the cigarette cartridge, the ejector pin contact spring 4 contacts the protective film layer with the ejector pin through the ejector pin contact spring 4 to prevent it from being crushed by the ejector pin.
[0037] The electronic cigarette oil enters the interior through the bottom of the porous ceramic base 1. The porous structure of this design not only allows the smoke oil to slowly penetrate through the tiny holes of the base, but also plays a role in filtering and evenly distributing the smoke oil. The adsorption properties of the porous ceramic material enable the smoke oil to be evenly transferred to the interior of the base without the phenomenon of excessive or insufficient local oil. The smoke oil enters the mounting groove 2 through the porous ceramic base 1. The mounting groove 2 is equivalent to a smoke oil storage area, which can ensure the continuous supply of smoke oil and avoid the phenomenon of insufficient oil supply in a short time. As the porous ceramic base 1 continuously introduces smoke oil, the smoke oil in the mounting groove 2 can always provide a steady supply of liquid for the atomization core, ensuring that the porous film ceramic atomization chip 5 is always in an oil-immersed state. This continuous immersion The design not only maintains the working efficiency of the atomization core, but also prevents problems such as dry burning. The design of the porous ceramic body 6 allows the smoke oil to be further transferred from the mounting groove 2 to the thin film heating layer 8. The porous ceramic material has a high capillary effect, so that the smoke oil can be effectively adsorbed and transferred to the heating layer. The porous structure also ensures the uniform distribution of the smoke oil before entering the heating layer, avoiding local overheating or insufficient oil supply. When the smoke oil passes through the porous ceramic body 6 to the thin film heating layer 8, the heating layer will heat up rapidly. The thin film heating layer 8 uses high thermal conductivity materials such as gold, silver, and platinum. It can reach the required temperature in a shorter time and maintain uniform heat distribution. Under the action of high temperature, nicotine, flavors and other ingredients in the smoke oil will quickly vaporize to produce uniform and delicate steam for users to inhale.
[0038] Reference Figure 2-Figure 4The porous ceramic base 1 is made of porous ceramic material, and the thin film coating transition layer 7 is made of titanium-aluminum alloy material, and one or more of titanium, zirconium, titanium-aluminum alloy, titanium-zirconium alloy, titanium-molybdenum alloy, titanium-niobium alloy, iron-aluminum alloy and tantalum-aluminum alloy can be selected. The thin film heating layer 8 is made of gold-silver-platinum alloy material, and copper layer, iron layer, nickel layer, chromium layer, gold layer, silver layer, platinum layer, palladium layer, molybdenum layer and other metal layers can be selected, as well as gold-silver alloy layer, gold-platinum alloy layer, gold-silver-platinum alloy layer, silver-palladium alloy layer, silver-platinum alloy layer, palladium-copper alloy layer, palladium-silver alloy layer, and nickel-chromium alloy layer. The porous ceramic body 6 is made of porous ceramic material, and the ejector pin contact spring 4 is made of palladium-silver alloy material, and titanium, copper, iron, nickel, chromium, gold, silver, platinum, palladium, molybdenum and other metal layers can be selected, as well as gold-silver alloy, gold-platinum alloy, gold-silver-platinum alloy, silver-palladium alloy, silver-platinum alloy, palladium-copper alloy, palladium-silver alloy, and nickel-chromium alloy layer.
[0039] By using porous ceramic materials and alloys such as gold, silver, platinum, palladium and silver, electronic cigarettes can achieve higher efficiency and stability in the process of oil transmission and heating. The porous ceramic base 1 and the porous ceramic body 6 ensure the continuous supply and uniform transmission of the oil, while the gold, silver and platinum alloy heating layer provides fast and uniform heating effect to ensure that the oil is fully atomized. At the same time, the excellent electrical contact performance of the palladium-silver alloy ensures a stable power supply for the entire system, ensuring the high efficiency and long life of the equipment.
[0040] Reference Figure 4-10 An oil guide groove 9 is provided at the bottom of the porous ceramic base 1 .
[0041] The electronic cigarette oil enters the porous ceramic base 1 from the oil guide groove 9 at the bottom, and is transferred from the porous ceramic base 1 to the upper mounting groove 2 through the porous structure inside the ceramic base.
[0042] Working principle: When the electronic cigarette oil needs to be atomized, the electronic cigarette oil enters the porous ceramic base 1 through the bottom of the porous ceramic base 1, and is then transferred to the inside of the mounting groove 2 through the porous structure inside the porous ceramic base 1. The mounting groove 2 continuously stores the oil, so that the porous film ceramic atomization chip 5 is always immersed in the electronic cigarette oil. The porous ceramic body 6 then transfers the electronic cigarette oil to the thin film heating layer 8, and the nicotine electronic cigarette oil is atomized through the thin film heating layer 8, thereby realizing the porous film ceramic atomization core nested structure to effectively supply oil to the heating plate, solving the atomization needs of large-capacity and high-power electronic cigarettes.
