Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and more specifically, to a ceramic atomizing core and heating element connection structure. Background Technology

[0002] Ceramic atomizing cores are the core components of electronic cigarettes, medical atomization devices, and other similar devices. They are widely used due to their excellent oil conductivity and chemical stability. Their working principle is as follows: heating elements (such as metal wires or alloy films) that are pressed, welded, or bonded to one side of the ceramic core body generate heat through electricity, causing the liquid adsorbed by the ceramic core to be atomized into an aerosol, thus meeting the needs of smoke generation or drug delivery.

[0003] Since the heating element is set on only one side of the ceramic atomizing core, it causes uneven heating of the ceramic core surface, affecting the atomization quality. It also causes nearly half of the heat of the heating element to be lost into the air, resulting in slow ceramic heating and delayed atomization start-up, which weakens the vaping experience. At the same time, the three traditional connection methods of pressing, welding and bonding all have defects. Under long-term hot and cold cycles and vibration, the pressing is prone to loosening, the welding core cracks and the bonding is prone to aging, which can cause the heating element to fall off, posing a safety hazard and reducing the durability of the equipment.

[0004] In summary, to improve the atomization quality, vaping experience, and reliability of ceramic atomizing cores, it is necessary to address the uneven heating and heat loss caused by the unilateral placement of the heating element, as well as the problem of easy detachment of the three traditional connection methods: pressing, welding, and bonding. This will enable ceramic atomizing cores to heat up faster, atomize more stably, and be safer and more durable for long-term use. Utility Model Content

[0005] The present invention provides a ceramic atomizing core and heating element connection structure, which aims to solve the problems of uneven heating and heat loss caused by the unilateral setting of the heating element, as well as the easy detachment of the three traditional connection methods of pressing, welding and bonding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ceramic atomizing core and heating element connection structure, comprising a lower ceramic substrate, an upper ceramic substrate disposed on the upper side of the lower ceramic substrate, a lower recessed groove disposed on the lower ceramic substrate, an upper recessed groove disposed on the upper ceramic substrate, a heating element inserted into the lower recessed groove and the upper recessed groove, two placement grooves disposed on the lower ceramic substrate and communicating with the lower recessed groove, positioning plates inserted into the placement grooves, two wire outlets disposed on the upper ceramic substrate and correspondingly communicating with the placement grooves, wires passing through the wire outlets, and a combined connection mechanism disposed on the lower ceramic substrate and the upper ceramic substrate, wherein the heating element and the two positioning plates are electrically connected, the two wires are electrically connected to the corresponding positioning plates respectively, and the combined connection mechanism is used to connect the lower ceramic substrate and the upper ceramic substrate.

[0007] In a preferred embodiment, both the lower ceramic substrate and the upper ceramic substrate are rectangular blocks, and their sides are symmetrically inclined.

[0008] In a preferred embodiment, the heating element consists of a plurality of circular heating elements with notches and a connecting heating element for connecting two adjacent circular heating elements, both of which are made of iron-chromium-aluminum alloy.

[0009] In a preferred embodiment, the combined connection mechanism includes a positioning module installed on the lower ceramic substrate and the upper ceramic substrate, and a locking module installed on the input end of the positioning module. The locking module drives the lower ceramic substrate and the upper ceramic substrate to combine and fix each other through the positioning module.

[0010] In a preferred embodiment, the positioning module includes four positioning holes symmetrically arranged on the upper ceramic substrate and positioning posts movably disposed in each positioning hole, with each positioning post fixedly connected to the lower ceramic substrate.

[0011] In a preferred embodiment, the locking module includes an enlarged hole formed on the upper ceramic substrate and communicating with each positioning hole, a threaded post set in each enlarged hole, an internal threaded sleeve threaded to the outside of each threaded post, and a rotating auxiliary buckle fixedly connected to the outside of the internal threaded sleeve, wherein each threaded post is fixedly connected to the corresponding positioning post.

[0012] In a preferred embodiment, the bottom of the positioning plate is fixedly connected with multiple pins, and the mounting groove is provided with a socket adapted to the insertion of each pin.

[0013] In a preferred embodiment, a locking frame is fixedly connected to the lower ceramic substrate, and a locking groove adapted to the insertion of the locking frame is provided on the upper ceramic substrate.

[0014] The beneficial effects of this utility model are as follows: This invention conceals the heating element within a closed space formed by the lower and upper recesses of the upper and lower ceramic substrates. It also employs a mesh-like spiral structure composed of a notched circular heating element and connecting heating elements. This significantly reduces heat loss to the air, thereby improving heat utilization and shortening the atomization start-up delay. Simultaneously, it allows for more uniform heating coverage to control the temperature difference on the surface of the ceramic core. Furthermore, it isolates the heating element from liquid erosion and friction, enhancing its durability and improving atomization quality and vaping experience.

[0015] This utility model uses a pre-connected wire positioning plate, positioning post and locking frame for dual positioning, combined with a threaded locking assembly mechanism, to quickly and accurately complete assembly without professional tools to improve mass production efficiency. The resulting triple fixing structure can offset thermal expansion and contraction and equipment vibration, greatly reducing the shedding rate of the heating element after long-term use, while preventing liquid from seeping into the circuit, thus improving the overall reliability and safety of the equipment.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Refer to the instruction manual appendix Figures 1 to 7A ceramic atomizing core and heating element connection structure includes a lower ceramic substrate 1, an upper ceramic substrate 2 disposed on the upper side of the lower ceramic substrate 1, a lower recessed groove 3 opened on the lower ceramic substrate 1, an upper recessed groove 4 opened on the upper ceramic substrate 2, a heating element 5 inserted into the lower recessed groove 3 and the upper recessed groove 4, two placement grooves 6 opened on the lower ceramic substrate 1 and communicating with the lower recessed groove 3, positioning plates 7 inserted into the placement grooves 6, two wire outlet holes 8 opened on the upper ceramic substrate 2 and correspondingly communicating with the placement grooves 6, wires 10 passing through the wire outlet holes 8, and a combined connection mechanism disposed on the lower ceramic substrate 1 and the upper ceramic substrate 2. The heating element 5 and the two positioning plates 7 are electrically connected, and the two wires 10 are electrically connected to the corresponding positioning plates 7 respectively. The combined connection mechanism is used to connect the lower ceramic substrate 1 and the upper ceramic substrate 2.

[0026] It should be noted that the heating element 5 is completely enclosed within the closed space formed by the lower storage groove 3 and the upper storage groove 4, which minimizes heat loss to the air and significantly improves heat utilization compared to the traditional single-sided surface. The positioning plate 7 is electrically connected to the heating element 5, which can assist in heating and evenly conduct heat to the interior of the ceramic core, avoiding local overheating caused by a single heating element 5. When the wire 10 is led out through the wire outlet hole 8, the inner wall of the hole is rounded to prevent the wire 10 from being damaged by friction with the ceramic edge due to vibration. At the same time, the wire outlet hole 8 and the wire 10 are filled with high-temperature resistant sealant to prevent atomized liquid from seeping in and affecting the circuit. The combined connection mechanism replaces the traditional crimping and welding methods, structurally solving the problem of the heating element 5 being prone to falling off after long-term use.

[0027] Refer to the instruction manual appendix Figure 1 Both the lower ceramic substrate 1 and the upper ceramic substrate 2 are rectangular blocks, and their sides are symmetrical inclined surfaces.

[0028] It should be noted that the side tilt angles of the lower ceramic substrate 1 and the upper ceramic substrate 2 are set at 15-20°. This angle design increases the overall surface area of ​​the core by 25%-30% compared to the straight-edge structure. The larger surface area allows the atomized aerosol to spread quickly on the surface, reducing local smoke accumulation and increasing the amount of smoke during a single inhale. At the same time, the tilted surface can guide the liquid to flow evenly along the surface, avoiding liquid residue at the edge of the core, reducing the problem of incomplete atomization caused by liquid accumulation, and further optimizing the inhale experience.

[0029] Refer to the instruction manual appendix Figure 3 The heating element 5 consists of multiple circular heating elements 501 with notches and a connecting heating element 502 for connecting two adjacent circular heating elements 501, both of which are made of iron-chromium-aluminum alloy.

[0030] It should be noted that adjacent heating elements 501 are connected in series with heating elements 502 to form a mesh spiral heating structure, covering a large heating area inside the ceramic core; the iron-chromium-aluminum alloy material can withstand temperatures above 600℃ and is not easily oxidized when subjected to atomization working temperatures of 180-220℃ for a long time, and the resistance value fluctuation is controlled within ±2%, which can ensure stable heating power and avoid fluctuations in atomization volume caused by the performance degradation of heating element 5.

[0031] Another alternative embodiment based on the design of heating element 5: The original heating element 5, consisting of a "circular heating element 501 with a notch + connecting heating element 502", can be replaced with a "double-helix wavy heating strip" structure. Specifically, the heating element 5 is formed by bending a single iron-chromium-aluminum alloy wire (0.2mm in diameter) into a double-helix wavy shape. The helix diameter is 3mm, the spacing between adjacent helices is 1.5mm, and the height difference between the peaks and troughs of the wave is 0.8mm. Both ends of the heating strip extend into the mounting groove 6 and are electrically connected to the positioning plate 7. In this structure, the heating element 5 forms an internal shape... The three-dimensional heating network provides a larger coverage area than the original embodiment, and the double-helix design allows heat to diffuse in both radial and axial directions within the ceramic core, avoiding the problem of localized heat concentration that is common with circular heating elements. The wavy crests can fit tightly against the internal groove walls, improving heat conduction efficiency compared to the original embodiment and further shortening the atomization start-up delay. At the same time, the single heating strip reduces the number of splicing points connecting the heating elements 502, reducing the risk of contact resistance fluctuations. Even after long-term use, the resistance value fluctuation can still be controlled within ±1.5%, resulting in better heating stability.

[0032] Refer to the instruction manual appendix Figure 2 The combined connection mechanism includes a positioning module installed on the lower ceramic substrate 1 and the upper ceramic substrate 2, and a locking module installed on the input end of the positioning module. The locking module drives the lower ceramic substrate 1 and the upper ceramic substrate 2 to combine and fix each other through the positioning module.

[0033] It should be noted that the positioning module first achieves the initial alignment of the lower ceramic substrate 1 and the upper ceramic substrate 2, ensuring that the lower storage groove 3 and the upper storage groove 4 are precisely connected, preventing the heating element 5 from shifting or deforming under pressure during the splicing process; the locking module provides a continuous and adjustable fixing force based on the positioning, so that the gap between the upper and lower cores after splicing is less than 0.05mm. This can not only prevent the atomized liquid from seeping into the storage groove and affecting the heating element 5, but also offset the slight deformation caused by the hot and cold cycle, prevent cracking at the core splicing point, and improve the durability of the overall structure.

[0034] Refer to the instruction manual appendix Figures 4 to 5 The positioning module includes four positioning holes 902 symmetrically arranged on the upper ceramic substrate 2 and positioning posts 901 movably disposed in each positioning hole 902, and each positioning post 901 is fixedly connected to the lower ceramic substrate 1.

[0035] It should be noted that the four positioning holes 902 and the positioning posts 901 are arranged in a rectangular pattern. The rectangular layout has higher positioning accuracy than other distribution methods, which can ensure that the alignment error between the lower recessed groove 3 and the upper recessed groove 4 is less than 0.02mm when the upper ceramic substrate 2 is closed. The heating element 5 can be completely attached to the groove wall, avoiding the heating element 5 being partially suspended and heat conduction being blocked due to misalignment of the groove. The top of the positioning post 901 is hemispherical. When it is inserted into the positioning hole 902, it can guide the core to automatically correct its position, reduce the assembly difficulty, and improve the assembly efficiency during mass production.

[0036] Refer to the instruction manual appendix Figures 4 to 7 The locking module includes an enlarged hole 903 opened on the upper ceramic substrate 2 and connected to each positioning hole 902, a threaded post 904 disposed in each enlarged hole 903, an inner threaded sleeve 905 threadedly connected to the outside of each threaded post 904, and a rotating auxiliary buckle 906 fixedly connected to the outside of the inner threaded sleeve 905. Each threaded post 904 is fixedly connected to the corresponding positioning post 901.

[0037] It should be noted that the rotating auxiliary buckle 906 on the internal threaded sleeve 905 can assist in tightening, and can be tightened by hand without tools to achieve quick locking, which is suitable for efficient assembly during mass production; the threaded head 904 and the positioning post 901 are integrally formed to avoid loosening of the connection caused by the splicing structure, and ensure that the locking force can be stably transmitted to the upper and lower cores, further improving the reliability of the connection.

[0038] Another feasible embodiment based on the combined connection mechanism design: the original positioning module of "positioning pin 901 + threaded locking" can be replaced with a "magnetic positioning pin + elastic buckle" structure. Specifically, four cylindrical magnetic positioning pins (2mm in diameter, 3mm in length, with built-in neodymium iron boron magnetic cores) are fixedly connected to the lower ceramic substrate 1. Four matching magnetic positioning holes (3mm deep, with a 0.3μm thick iron-nickel alloy layer plated on the hole wall) are opened at corresponding positions on the upper ceramic substrate 2. At the same time, two elastic buckles (made of ceramic matrix composite material, with a deformation stroke of 0.5mm) are symmetrically arranged on the edge of the lower ceramic substrate 1. Two snap-fit ​​grooves (1mm deep) are opened at corresponding positions on the ceramic substrate 2. During assembly, the magnetic positioning pin and the magnetic positioning hole are quickly positioned by magnetic attraction (positioning error ≤0.03mm). The elastic snap-fit ​​automatically snaps into the snap-fit ​​groove to achieve secondary fixation. Locking can be completed without rotating the internal thread sleeve 905. Compared with the original embodiment, this structure significantly shortens the assembly time and avoids the problem of thread stripping after long-term use of threaded connections. It is more suitable for high-frequency disassembly and assembly scenarios. At the same time, the dual fixation of magnetic attraction and snap-fit ​​can still ensure that the gap between the upper and lower cores is ≤0.05mm, which does not affect the sealing effect of the heating element 5.

[0039] Refer to the instruction manual appendix Figures 3 to 4The bottom of the positioning plate 7 is fixedly connected with multiple insertion posts 11, and the mounting groove 6 is provided with insertion holes 12 adapted to each insertion post 11.

[0040] It should be noted that the insertion post 11 at the bottom of the positioning plate 7 can prevent the positioning plate 7 from rotating or shifting in the placement groove 6 due to vibration or thermal expansion and contraction; the inner wall of the insertion hole 12 is plated with a 0.5μm thick nickel layer, which can reduce the contact resistance between the insertion post 11 and the insertion hole 12, making the current conduction between the positioning plate 7 and the heating element 5 smoother, avoiding the problem of local heating and increased energy consumption caused by excessive contact resistance; the mating gap between the insertion post 11 and the insertion hole 12 is controlled at 0.01mm to ensure that the positioning plate 7 is in close contact with the lower ceramic substrate 1 and improve the heat conduction efficiency.

[0041] Refer to the instruction manual appendix Figures 5 to 6 A locking frame 13 is fixedly connected to the lower ceramic substrate 1, and a locking groove 14 adapted to the locking frame 13 is provided on the upper ceramic substrate 2.

[0042] It should be noted that the height of the locking frame 13 is perfectly matched with the depth of the locking groove 14. After locking, the frame and the groove wall fit tightly together to form a ring-shaped sealing structure, which can effectively prevent the atomized liquid from leaking from the splicing gap between the upper ceramic substrate 1 and the lower ceramic substrate 2, and avoid liquid seeping into the circuit and causing malfunctions. At the same time, the locking frame 13 is made of elastic ceramic material (with 5% zirconium oxide added), which has slight deformation capability and can compensate for the slight expansion and contraction of the core during hot and cold cycles, preventing the frame or groove from cracking due to rigid splicing. Together with the positioning module and the locking module, a "triple fixation" structure is formed, which further reduces the risk of the heating element 5 falling off.

[0043] Working principle: I. Assembly and Connection Steps 1. Place the heating element 5 in the lower recess 3 of the lower ceramic substrate 1, and then insert the positioning plate 7 into the insertion hole 12 of the placement groove 6 through the bottom insertion post 11 so that the positioning plate 7 and the heating element 5 form a stable electrical contact. Then, pass two wires 10 through the two outlet holes 8 of the upper ceramic substrate 2 from the top. 2. Further align the positioning post 901 of the lower ceramic substrate 1 with the positioning hole 902 of the upper ceramic substrate 2, and at the same time, let the locking frame 13 of the lower ceramic substrate 1 engage with the locking groove 14 of the upper ceramic substrate 2 to complete the initial splicing and positioning of the upper and lower cores. 3. Rotate the rotating auxiliary buckle 906 inside the enlarged hole 903 of the upper ceramic substrate 2 to drive the inner threaded sleeve 905 to tighten with the threaded column head 904, locking the lower ceramic substrate 1 and the upper ceramic substrate 2 into a whole. At this time, the heating element 5 is completely wrapped in the lower groove 3 and the upper groove 4. 4. Finally, fill the gap between the outlet hole 8 and the wire 10 with high-temperature resistant sealant to prevent the atomized liquid from seeping in, and complete the assembly.

[0044] II. Usage Process 1. Insert the assembled ceramic atomizing core into the atomizing device, so that the surface of the core comes into contact with the oil guiding structure of the device, ensuring that the liquid can penetrate evenly to the surfaces of the lower ceramic substrate 1 and the upper ceramic substrate 2; 2. After the equipment is powered on, the current is conducted to the positioning plate 7 through the wire 10, which then drives the heating element 5 to heat up. The heating element 5 is enclosed by the lower storage groove 3 and the upper storage groove 4, and the heat is efficiently conducted to the ceramic core. 3. After absorbing heat, the ceramic core atomizes the liquid permeating its surface into an aerosol. The increased surface area of ​​the inclined surface accelerates the diffusion of smoke. At the same time, the combined connection structure prevents the heating element 5 from falling off due to hot and cold cycles, thus achieving stable and efficient atomization output.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
