Description

Technical Field

[0001] This utility model relates to the field of core technology, and in particular to a microporous ceramic atomizing core with a multi-film structure. Background Technology

[0002] Ceramic atomizing cores are functional structural ceramics made through high-temperature sintering processes. They contain a large number of micron- or submicron-sized pores inside or on the surface, and are characterized by high temperature resistance, high mechanical strength, and adjustable porosity. Their core function is to achieve uniform adsorption and efficient atomization of e-liquid through the capillary effect and surface tension of the microporous structure.

[0003] Traditional microporous ceramic atomizing cores rely on capillary force generated by the uniformly distributed micropores within the ceramic body for wicking. The working principle is as follows: liquid e-liquid is adsorbed onto the atomizing surface embedded with the heating element under capillary action, and then atomized after heating. The wicking process depends entirely on the inherent, uniform capillary force of the material, and cannot be actively or adaptively adjusted according to the required atomization volume. At high power, it is prone to "not drawing in enough e-liquid"; at low power or when stationary, it may become "oversaturated" due to continuous wicking, leading to leakage. The contact surface between the heating element and the ceramic is usually a two-dimensional plane or shallow groove, resulting in a limited atomization reaction area and concentrated heat, which can easily lead to excessively high local temperatures, affecting atomization uniformity and efficiency. The difference in thermal expansion coefficients between the ceramic substrate and the metal heating element generates shear stress at the interface during thermal cycling, which can easily lead to microcracks at the interface with long-term use, causing poor contact and decreased thermal efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that traditional microporous ceramic atomizing cores rely entirely on passive and uniform capillary force to guide oil, and cannot adaptively adjust according to atomization needs, resulting in insufficient oil supply and dry burning at high power, and oversaturation and leakage at low power; its two-dimensional planar heating structure causes heat concentration and uneven atomization, and at the same time, the difference in thermal expansion between ceramic and metal causes microcracks at the interface during hot and cold cycles, resulting in poor contact and thermal efficiency reduction.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A microporous ceramic atomizing core with a multi-film structure includes a first ceramic core sleeve and a second ceramic core sleeve that are interlocked with each other. Several sets of adsorption tubes are distributed at the bottom of the second ceramic core sleeve, and the several sets of adsorption tubes are used to enhance the adsorption of e-liquid. Several sets of oil guide tubes are distributed at the top of the first ceramic core sleeve, and the several sets of oil guide tubes are used to guide the upward flow of e-liquid. A heating module is placed in the first ceramic core sleeve. A middle ring is provided at the junction of the first ceramic core sleeve and the second ceramic core sleeve. A suspension sleeve is attached to the inner wall of the middle ring, and a suspension cavity is opened in the suspension sleeve.

[0006] The beneficial effects of this invention are as follows: Through the stepped oil guiding structure of the adsorption tube, the suspension cavity, and the oil guiding tube, a synergistic oil supply of capillary adsorption and gravity self-adaptation is achieved: During high-power atomization, the adsorption tube and the oil guiding tube form a rapid oil replenishment channel to prevent dry burning; when stationary or at low power, the suspension cavity can temporarily store excess e-liquid and use its weak capillary characteristics to block continuous self-inhalation, fundamentally preventing leakage. The use of three sets of linearly distributed and radially arranged multi-ring heating modules upgrades the traditional two-dimensional planar heating to a three-dimensional thermal field, greatly increasing the effective atomization area, making the heat load evenly distributed, avoiding local high-temperature clogging, and significantly improving atomization uniformity and efficiency.

[0007] Furthermore, the hovering cavity is used to temporarily store and e-liquid, and the two ends of the hovering sleeve are fitted with diaphragms, which are used for the insertion and installation of the adsorption tube and the oil guide tube.

[0008] Furthermore, the hovering sleeve has several sets of storage sacs distributed in a circle, and these sets of storage sacs are connected by heating wires. The heating wires are connected to connecting wires that extend to the heating module, and several sets of adsorption holes are distributed on the storage sacs.

[0009] Furthermore, a micron-sized capillary is connected to the adsorption tube, a protective ring is fastened to the outer ring of the membrane, and a conductive connector is connected to the adsorption tube through the membrane.

[0010] Furthermore, the heating module is arranged in three linear groups. The heating module includes heating rings, which are arranged in several groups. The heating rings are radially distributed from the inside to the outside, and the diameter of the heating rings increases from the inside to the outside. The centers of each heating ring overlap. Furthermore, several sets of heating rings are connected by extension tubes, with heating tungsten blocks inside the extension tubes. The innermost heating ring contains a heating module, which contains an electrically connected wireless signal module, a lithium battery pack, and a heater. Several sets of guide tubes are circumferentially installed on the outermost heating ring, with flashing lights installed at the ends of the guide tubes. The three sets of linear heating modules are connected by conductive tubes and a connecting light installed on the top.

[0011] Furthermore, the second ceramic core sleeve is circumferentially equipped with several sets of counterweights and a built-in gyroscope. Ear plates are fixed to the counterweights, and several sets of lifting holes are distributed on the ear plates.

[0012] Furthermore, the outer ring of the first ceramic core sleeve is equipped with several sets of temperature gauges, each with a built-in temperature sensor, and an expansion ring is integrated at the far end of the first and second ceramic core sleeves.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the flexible sandwich structure formed by the hovering sleeve and the diaphragm, as well as the expansion ring outside the ceramic core, jointly absorb the shear stress caused by the difference in thermal expansion coefficients between the ceramic substrate and the metal heating wire, effectively suppressing the generation of interface microcracks and ensuring the long-term stability and high thermal efficiency of the thermal contact interface.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0018] Example 1; as Figures 1-5As shown, it includes a first ceramic core sleeve 1 and a second ceramic core sleeve 2 that are interlocked with each other. The bottom of the second ceramic core sleeve 2 is provided with several sets of adsorption tubes 5, which are used to actively lift and adsorb e-liquid from the oil storage tank. The top of the first ceramic core sleeve 1 is provided with several sets of oil guide tubes 4, which are responsible for guiding the oil upward to the core heating area. The heating module 3 is placed inside the first ceramic core sleeve 1 and is the key component for generating heat to achieve atomization. At the junction of the first ceramic core sleeve 1 and the second ceramic core sleeve 2, a middle ring 102 is provided. A hovering sleeve 204 is tightly fitted to the inner wall of the middle ring 102. A hovering cavity 205 is opened inside the hovering sleeve 204. This cavity serves as a key buffer and temporary storage area in the oil circuit system, which can balance the oil supply demand under different power levels. A precision diaphragm 503 is fitted to each of the upper and lower end faces of the hovering sleeve 204. These two diaphragms 503 not only play a sealing role, but their specific structure also provides a channel and support for the insertion and installation of the bottom adsorption tube 5 and the top oil guide tube 4, together forming a preliminary and adjustable oil guide path.

[0019] During operation, the e-liquid is first adsorbed upwards by the capillary action generated by the adsorption tube 5 at the bottom of the second ceramic core sleeve 2. The micron-level capillary tube 501 connected to the adsorption tube 5 further enhances this capillary effect, ensuring the stability of the initial oil guiding. The oil then gathers and is temporarily stored in the suspension cavity 205 formed by the suspension sleeve 204. This suspension cavity 205 acts as an intelligent oil transfer station, which can dynamically adjust the amount of oil delivered to the upper oil guiding tube 4 through the diaphragms 503 at both ends according to the working status (power level) of the downstream heating module 3. Finally, the oil passes through the diaphragm 503 and enters the oil guiding tube 4 at the top of the first ceramic core sleeve 1, where it is precisely delivered to the heating module 3 to wait for atomization.

[0020] Example 2: Please refer to Figure 1 - Figure 6 Based on the multi-membrane 503 structure provided in Example 1, this example has enhanced functionality.

[0021] First, several sets of storage bladders 206 are added in a circular distribution on the hovering sleeve 204. These storage bladders 206 are interconnected by a surrounding heating wire 207, and the heating wire 207 extends to the main heating module 3 through a connecting wire 209, which can provide auxiliary heating to ensure that the oil maintains a suitable viscosity before entering the main heating zone. Each storage bladder 206 has numerous adsorption holes 208 distributed on its surface, which increases the contact area with the e-liquid and plays a role in secondary oil equalization and oil storage. Secondly, the heating module 3 adopts three linear arrangements, which constitute the core heat source of the system. Each heating module 3 contains several heating rings 301. These heating rings 301 are distributed radially from the inside to the outside, and their diameters increase sequentially. The centers of all heating rings 301 overlap each other, forming a broad and uniform three-dimensional heating surface. Each heating ring 301 is connected by an extension tube 302. A heating tungsten block is placed inside the extension tube 302 to ensure efficient heat conduction throughout the heating network. The core heating module 303 is integrated within the innermost heating ring 301. This module incorporates an electrically connected wireless signal module, a lithium battery pack, and a heater, enabling wireless communication and independent power supply for the atomizer core. A guide tube 304 is circumferentially mounted on the outermost heating ring 301. A flashing light 101 at its end and a top-mounted light 306 provide visual feedback on the operating status. Furthermore, this embodiment introduces an intelligent sensing and balancing system. Several counterweights 201 and their built-in gyroscope sensors (ADXRS645 model is recommended, which has a wide operating temperature range of -40°C to +175°C and excellent shock and vibration resistance, making it suitable for this high-temperature working environment) are installed on the outer ring of the second ceramic core sleeve 2. The ear plates 202 and their lifting holes 203 fixed on the counterweights 201 facilitate the installation and fixation of the overall structure. On the outer ring of the first ceramic core sleeve 1, several built-in temperature sensors (common NTC thermistors, such as the MF52 series) of temperature gauges 103 are installed for real-time monitoring of the atomizing core temperature. In addition, at the ends of the first ceramic core sleeve 1 and the second ceramic core sleeve 2 that are far apart, an expansion ring 104 is integrated. This structure is usually made of a flexible metal alloy (such as 304 stainless steel) or high-temperature resistant silicone rubber, and is used to absorb the dimensional changes caused by the difference in thermal expansion coefficients between ceramic and metal parts, and to relieve internal stress.

[0022] During operation, the gyroscope continuously monitors the attitude and motion of the atomizing core. This signal can be transmitted to the main unit via a wireless signal module to enable intelligent power-on and power-off functions such as "raise your hand to inhale". The temperature sensor provides real-time feedback on the heating zone temperature and works in conjunction with the main unit to achieve precise temperature control (TC) to prevent dry burning. The design of the storage bladder 206 and auxiliary heating wire 207 ensures that even under continuous high power output, sufficient oil supply can be guaranteed through preheating and additional oil storage. The radial three-dimensional heating ring 301 maximizes the heating area in contact with the oil, resulting in faster and more uniform atomization, which greatly improves the flavor and vapor production. The expansion ring 104 effectively compensates for the thermal expansion differences between materials through its own slight deformation when the entire system undergoes hot and cold cycles, protecting the internal precision structure and extending its service life.

[0023] The above working principle can be summarized as follows: through the multi-stage, adjustable oil guiding path formed by the adsorption tube 5, the hovering chamber 205 and the oil guiding tube 4, the limitation of the traditional atomizing core relying solely on passive capillary force is broken, and adaptive oil guiding according to power requirements is realized. Its core three-dimensional radial heating module 3 upgrades the traditional two-dimensional planar heating to three-dimensional spatial heating, which greatly improves thermal efficiency and atomization uniformity. The gyroscope and temperature sensor integrated on the ceramic core sleeve give the atomizing core sensing capabilities, laying the foundation for intelligent control and safety protection. The introduction of the expansion ring 104 solves the reliability problem caused by the mismatch of the thermal expansion coefficients of materials during long-term use from the perspective of structural mechanics. By employing a multi-diaphragm 503 structure for oil circuit management, a three-dimensional heating layout to improve atomization efficiency, and the active introduction of intelligent sensing and buffer structures to enhance overall performance and durability, this invention systematically solves the inherent defects of traditional ceramic atomizing cores in terms of oil guiding, heating, and structural reliability. The ceramic matrix is ​​preferably made of alumina ceramic with a purity of 95% or higher, sintered at temperatures above 1700°C to ensure the stability of its microporous structure, mechanical strength, and thermal stability. For the heating element, the heating ring 301 and heating wire 207 can be made of high-performance resistive materials such as nickel-chromium alloys (e.g., Cr20Ni80) or iron-chromium-aluminum alloys (e.g., AISI314). This ingenious combination of materials and structure contributes to the superior technical performance of this invention.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
