[0002] In atomizers, the atomizer core is heated to convert the atomized matrix into a usable state. In conventional atomizers, the core's porous structure allows it to retain a certain amount of atomized matrix, ensuring a smooth atomization process. The core can store and conduct liquid through micropores, and can also lock in liquid through the flow resistance of the micropores, thereby preventing the risk of leakage. Summary of the Invention

[0003] In a first aspect of the present disclosure, a substrate for an atomizer core is provided. The substrate includes a first side arranged to face a liquid storage tank of an atomizer device; a second side arranged to face away from the first side; and a plurality of through-holes extending through the first and second sides to allow atomized substrate flowing from the first side to flow to the second side. Each through-hole includes a liquid-locking section, the cross-sectional area of which gradually decreases along an extension direction from the first side to the second side.

[0004] In some embodiments, the pore size ratio of the liquid locking segment is in the range of 5:1 to 1:1.

[0005] In some embodiments, the through hole includes a liquid inlet and a liquid outlet respectively located at ends in the extension direction, and the cross-sectional shapes of the liquid inlet and the liquid outlet are circular.

[0006] In some embodiments, the liquid inlet and the liquid outlet are arranged at both ends of the liquid locking section in the extension direction, and the cross-sectional area of the liquid inlet is larger than the cross-sectional area of the liquid outlet.

[0007] In some embodiments, each through hole further includes a liquid guiding segment formed upstream or downstream of the liquid locking segment.

[0008] In some embodiments, the liquid guiding section is formed downstream of the liquid locking section, and the cross-sectional area of the liquid guiding section remains unchanged or gradually increases along the extension direction.

[0009] In some embodiments, the aperture ratio of the liquid-conducting segment is in the range of 1:1 to 1:5.

[0010] In some embodiments, the length of the liquid locking section in the extension direction is greater than or equal to the length of the liquid guiding section in the extension direction.

[0011] In some embodiments, the liquid guiding section is arranged upstream of the liquid locking section, and the cross-sectional area of the liquid guiding section gradually increases along the extension direction.

[0012] In some embodiments, the length of the liquid locking section in the extension direction is less than or equal to the length of the liquid guiding section in the extension direction.

[0013] In some embodiments, the heat generating element further includes a plurality of air holes, and the plurality of air holes respectively correspond to corresponding through holes in the plurality of through holes.

[0014] A second aspect of the present disclosure provides an atomizer core, which includes a substrate according to the first aspect of the present disclosure and a heating element disposed on at least one of a first side and a second side of the substrate to heat an atomized substrate.

[0015] In a third aspect of the present disclosure, an atomization device is provided, comprising: an atomization core according to the second aspect of the present disclosure.

[0016] In an embodiment of the present disclosure, the substrate includes a first side, a second side, and a plurality of through holes. The first side faces the liquid storage tank of the atomizing device. The second side is opposite to the first side. A plurality of through holes penetrate the first side and the second side. The atomized matrix flowing in from the first side can flow to the second side. Each through hole includes a liquid locking section. The cross-sectional area of the liquid locking section gradually decreases along the extension direction from the first side to the second side. With this arrangement, the liquid locking section can increase the liquid storage amount of the atomized matrix in the through hole, thereby improving the supply capacity of the atomized matrix. At the same time, the cross-sectional area of the liquid locking section close to the second side is smaller, which can not only make the atomized matrix closer to the second side through capillary force, but also increase the flow resistance of the atomized matrix, thereby reducing the risk of leakage.

[0017] It should be understood that the content described in this content section is not intended to limit the key features or important features of the embodiments of the present disclosure, nor is it intended to limit the scope of the present disclosure.

[0028] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] As used herein, the term "including" and its variations represent open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based at least in part on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment." The terms "first," "second," etc. may refer to different or identical objects.

[0030] As mentioned above, the atomizer core can store and conduct liquid through the micropores, and can also lock the liquid through the flow resistance of the micropores, thereby avoiding the risk of leakage. In some conventional atomizer cores, if the cross-sectional area of the micropores is large, although the storage amount of the atomized matrix in the micropores can be increased, the excessive pore size will also lead to leakage risks. If the cross-sectional area of the micropores is small, although the leakage risk of the atomized matrix can be reduced, the insufficient storage amount of the atomized matrix in the micropores will affect the supply of the atomized matrix to the heating element, thereby affecting the atomization effect.

[0031] Embodiments of the present disclosure provide a substrate for an atomizer core, an atomizer core for an atomizer device, and an atomizer device. The atomizer core includes a substrate and a heating element. The substrate includes a first side, a second side, and a plurality of through holes. The first side faces the liquid storage tank of the atomizer device. The second side is opposite to the first side. A plurality of through holes pass through the first side and the second side. The atomized matrix flowing in from the first side can flow to the second side. Each through hole includes a liquid locking section. The cross-sectional area of the liquid locking section gradually decreases along the extension direction from the first side to the second side. The heating element is coupled to the substrate on the second side. The heating element can heat the atomized matrix on the second side. With this arrangement, the liquid locking section can increase the liquid storage amount of the atomized matrix in the through hole, thereby improving the supply capacity of the atomized matrix. At the same time, the cross-sectional area of the liquid locking section close to the second side is smaller, which can not only bring the atomized matrix closer to the second side through capillary force, but also increase the flow resistance of the atomized matrix, thereby reducing the risk of leakage.

[0032] The following will be combined Figures 1 to 8 To describe the principles of the present disclosure in detail, Figures 1 to 3 The structure of the atomizer core 100 of the first embodiment of the present disclosure is shown. Figure 4 The structure of the atomizer core 100 of the second embodiment of the present disclosure is shown. Figure 5 The structure of the atomizer core 100 of the third embodiment of the present disclosure is shown. Figure 6 The structure of the atomizer core 100 of the fourth embodiment of the present disclosure is shown. Figure 7 The structure of the atomizer core 100 of the fifth embodiment of the present disclosure is shown. Figure 8 The structure of the atomizer core 100 of the sixth embodiment of the present disclosure is shown. Figures 1 to 3 The principle of the atomizer core 100 of the first embodiment of the present disclosure will be described in detail.

[0033] like Figures 1 to 3 As shown, the atomizer core 100 includes a substrate 10 and a heating element 20. The substrate 10 serves as the foundational structure of the atomizer core 100 and a transmission channel for the atomized matrix. It can be made of dense materials such as silicon wafers, glass, or ceramics. The substrate 10 has excellent high-temperature resistance and anti-permeability capabilities, which can enhance the stability and service life of the atomizer core 100. Even in long-term high-temperature environments, the substrate 10 can maintain its structure without significant deformation or ablation.

[0034] like Figures 1 to 3As shown, the substrate 10 includes a first side 101, a second side 102, and a plurality of through holes 11. The first side 101 faces the liquid storage chamber 301 of the atomizing device 300 and can receive the atomized substrate in the liquid storage chamber 301. The second side 102 is opposite to the first side 101 and is close to the area where the heating element 20 is located. The plurality of through holes 11 penetrate the first side 101 and the second side 102. In this way, the atomized substrate in the liquid storage chamber 301 can flow from the first side 101 to the second side 102 via the plurality of through holes 11.

[0035] like Figures 1 to 3 As shown, each through hole 11 includes a liquid locking section 111. The cross-sectional area of the liquid locking section 111 gradually decreases along the extension direction from the first side 101 to the second side 102. The liquid locking section 111 has a larger inlet, which can provide a larger liquid storage space for the through hole 11, helping to store more atomized matrix in the through hole 11, thereby improving the continuous liquid supply capacity. As the liquid locking section 111 extends toward the second side 102, the cross-sectional area of the liquid locking section 111 gradually decreases. The liquid locking section 111 can form a tapered funnel structure. In this way, the end of the funnel increases the resistance of the atomized matrix during the flow process, thereby making it difficult for the atomized matrix to flow out due to external vibrations or changes in air pressure, which helps to improve the liquid locking ability of the through hole 11. In addition, due to the presence of capillary action, after entering the liquid locking section 111, the atomized matrix tends to move along the inner wall of the liquid locking section 111 to the narrower end, so that the atomized matrix can fully flow to the second side 102 of the atomizing core 100 before heating.

[0036] like Figures 1 to 3 As shown, the heating element 20 is coupled to the substrate 10 on the second side 102. As an example, the heating element 20 may include a heating sheet made of stainless steel, nickel, nickel-chromium alloy, titanium, or graphene. In this manner, the heating element 20 may be mounted on the second side 102 of the substrate 10 by bonding, welding, or other means.

[0037] As another example, a printing process can also be used to form a heating layer on the second side 102 of the substrate 10. For example, suitable metal powder (such as silver, copper, nickel, etc.) is selected as needed, and mixed with the carrier to prepare a slurry. The slurry is then coated on the surface of the substrate 10 by screen printing, gravure printing, etc. After printing is completed, it is dried and sintered under high temperature conditions to fuse the metal particles to form a dense and well-conductive heating layer. In some embodiments, the printed pattern can also be adjusted according to the heating requirements to ensure consistent atomization taste in different parts.

[0038] With this arrangement, the liquid-locking section 111 can increase the amount of liquid stored in the atomized substrate within the through-hole 11, thereby improving the supply capacity of the atomized substrate. Furthermore, the cross-sectional area of the end of the liquid-locking section 111 near the second side 102 is smaller. This not only draws the atomized substrate closer to the second side 102 through capillary force, but also increases the flow resistance of the atomized substrate, thereby increasing the liquid-locking capacity of the through-hole 11 and reducing the risk of leakage.

[0039] In some embodiments, as Figure 3 As shown, the through hole 11 includes a liquid inlet 1101 and a liquid discharge outlet 1102 respectively located at the ends of the extension direction. The liquid inlet 1101 is arranged on the first side 101 of the substrate 10, directly facing the liquid storage tank 301 of the atomizing device 300, and can receive the atomized matrix from the liquid storage tank 301. The liquid discharge outlet 1102 is located on the second side 102 of the substrate 10, and can discharge the atomized matrix stored in the liquid locking section 111 to facilitate heating and atomization. The cross-sectional area of the liquid inlet 1101 is larger than the cross-sectional area of the liquid discharge outlet 1102. In this way, the entire through hole 11 is funnel-shaped, which is not only conducive to the through hole 11 to absorb the atomized matrix from the liquid storage tank 301, but also can increase the resistance to the flow of the atomized matrix by the gradually narrowing channel, thereby improving the liquid locking ability and reducing the risk of leakage.

[0040] In some embodiments, the heating element 20 may be arranged on at least one of the first side 101 and the second side 102. That is, in some embodiments, the heating element 20 may be arranged on the second side 102 (classic layout). In some embodiments, the heating element 20 may be arranged on the first side 101. In addition, in some embodiments, the heating element 20 may be arranged on both the first side 101 and the second side 102. The following will focus on the classic layout in which the heating element 20 is arranged on the second side 102, and will also briefly explain the situation in which it is arranged on the first side 101 or on the first side 101 and the second side 102.

[0041] In this classic layout, the liquid locking section 111 of the through hole 11 plays a dual key role. First, the larger aperture portion close to the first side constitutes a micro liquid storage area that can cache a sufficient amount of atomized matrix. Secondly, its gradually smaller aperture close to the second side greatly enhances the capillary action. This capillary force will actively "pull" the atomized matrix to the surface of the heating element on the second side, ensuring continuous wetting of the atomizing surface. At the same time, the narrow aperture also increases the flow resistance of the liquid, effectively preventing the liquid from leaking from the second side under air pressure changes or vibrations. This is the core principle of "capillary traction and liquid locking to prevent leakage."

[0042] When the heating element is arranged on the first side, its core function is to stably and evenly heat the atomized matrix near the first side 101 and about to enter the through-hole 11, thereby significantly reducing its viscosity. This function is crucial for processing atomized matrices with high viscosity (viscosity unit value is above 10,000). After the viscosity is reduced, the fluidity of the liquid is greatly enhanced, and it can enter and flow through the through-hole 11 more easily and quickly. This ensures that the liquid supply channel to the second side 102 always remains unobstructed and efficient, fundamentally solving the problem of liquid supply delay or interruption caused by poor flow of high-viscosity liquids.

[0043] Furthermore, the heating element on the first side also serves as an atomizer. Heat is transferred from the first side 101 to the second side 102 through thermal conduction through the material of the substrate 10 itself. This means that when the atomized matrix flows to the outlet on the second side, it comes into contact not only with the residual heat of the preheated liquid itself, but also with the already heated substrate surface. This "double heating" effect makes it easier for the atomized matrix to reach its atomization point on the second side, achieving lower energy consumption and faster response.

[0044] In this mode, the tapered structure of the through hole 11 mainly plays its role in flow control and leak prevention, ensuring that the preheated and more fluid liquid can be supplied at a stable and controllable rate, while its narrow-diameter end can still effectively prevent accidental leakage of the liquid.

[0045] When the heating elements are arranged on both the first side 101 and the second side 102, the division of labor between the two groups of heating elements becomes clearer and more efficient. The heating element on the first side is capable of heating the atomized matrix to the optimal flow temperature, ensuring that even the liquid with the highest viscosity can be supplied to the second side smoothly and unimpeded. The heating element on the second side receives the preheated liquid that is stably supplied by the first side, and focuses on providing the thermal energy required for the final phase change, atomizing it with the highest efficiency. This division of labor of "first-level preheating and viscosity reduction, second-level precise atomization" makes the entire system respond quickly, work stably, and effectively improve energy efficiency, thereby improving the user experience.

[0046] In some embodiments, as Figure 3 As shown, the cross-sectional area of the liquid inlet 1101 is greater than the cross-sectional area of the liquid outlet 1102. The aperture ratio of the liquid locking section 111 can be in the range of 5:1 to 1:1. The aperture ratio of a tapered hole is a quantitative indicator used to describe the degree of tapering of a tapered hole. It is defined as the proportional relationship between the diameter of the widest part (large end) of the hole and the diameter of the narrowest part (small end). For non-circular cross-sections, the "aperture" referred to in this disclosure refers to the maximum length dimension that can define its boundary. For example, for a rectangular cross-section, the "aperture ratio" refers to the ratio of its corresponding side lengths.

[0047] As an example, the cross-sectional shape of the liquid inlet 1101 and the liquid discharge outlet 1102 of the through hole 11 can be circular, and the ratio of the diameter of the liquid inlet 1101 of the through hole 11 to the diameter of the liquid discharge outlet 1102 of the liquid locking section 111 is in the range of 5:1 to 1:1. In this way, the size of the liquid inlet 1101 is larger, which can increase the liquid storage capacity of the atomized substrate in the through hole 11. The size of the liquid discharge outlet 1102 of the liquid locking section 111 is smaller, which can increase the flow resistance of the atomized substrate, thereby increasing the liquid locking ability of the through hole 11.

[0048] In other embodiments, the cross-sectional shapes of the liquid inlet 1101 and the liquid outlet 1102 of the through hole 11 can be rectangular, square, or diamond, etc., and the ratio of the length of one side of the liquid inlet 1101 to the length of the corresponding side of the liquid outlet 1102 is in the range of 5:1 to 1:1.

[0049] In some embodiments, as Figure 1 and Figure 2 As shown, the heating element 20 further includes a plurality of air holes 21. The plurality of air holes 21 correspond to corresponding through holes 11 in the plurality of through holes 11. In this manner, the atomized substrate flowing from the through holes 11 to the second side 102 is heated and atomized by the heating element. The aerosol formed after atomization can then enter the inhalation channel along the plurality of air holes 21, thereby being consumed by the user.

[0050] The following will be combined Figure 4 The structure and combination of the atomizer core 100 of the second embodiment of the present disclosure are described in detail. Figures 1 to 3 A part of the structure of the first embodiment described is similar. In the following, the differences between them will be mainly described, and the same parts will not be repeated.

[0051] like Figure 4 As shown, each through hole 11 also includes a liquid conducting section 112. The liquid conducting section 112 is arranged downstream of the liquid locking section 111. That is to say, the liquid inlet 11 of the through hole 11 is the opening of the liquid locking section 111 on the first side 101, and the liquid discharge outlet 102 is the opening of the liquid conducting section 112 on the second side 102. The atomized matrix in the liquid storage chamber enters the liquid locking section 111 along the through hole 11, and then enters the liquid conducting section 112 from the liquid locking section 111. The liquid locking section 111 can increase the liquid storage amount of the atomized matrix in the through hole 11, thereby improving the atomization effect. The cross-sectional area of the liquid locking section 111 close to the second side 102 is smaller, and the capillary force can be used to make the atomized matrix easier to enter the liquid conducting section 112, so that the atomized matrix can flow smoothly to the heating element 20 for heating and atomization.

[0052] In some embodiments, as Figure 4As shown, the cross-sectional area of the liquid guiding section 112 remains constant along the extension direction. In this way, the flow channel of the liquid guiding section 112 is a flow channel with a constant diameter, which helps to maintain the uniformity and continuity of the flow of the atomized substrate.

[0053] The following will be combined Figure 5 The structure and combination of the atomizer core 100 of the third embodiment of the present disclosure are described in detail. Figure 4 A part of the structure of the second embodiment described is similar. In the following, the differences between them will be mainly described, and the same parts will not be repeated.

[0054] like Figure 5 As shown, the liquid guiding section 112 is arranged downstream of the liquid locking section 111. The atomized matrix in the liquid storage chamber enters the liquid locking section 111 along the through hole 11, and then enters the liquid guiding section 112 from the liquid locking section 111. The liquid locking section 111 can increase the liquid storage capacity of the atomized matrix in the through hole 11, thereby improving the atomization effect. The cross-sectional area of the liquid guiding section 112 gradually increases along the extension direction. In this way, the flow channel of the liquid guiding section 112 is an inverted funnel-shaped structure. The enlarged discharge outlet 1102 of the liquid guiding section 112 can reduce the flow velocity of the atomized matrix, so that it flows evenly to the surface of the heating element 20, which helps to improve the atomization effect of the heating element 20.

[0055] In some embodiments, as Figure 5 As shown, the liquid guiding section 112 includes an inlet near the liquid locking section 111 and an outlet near the second side 102 (i.e., the drainage outlet 1102 of the through hole). Since the cross-sectional area of the liquid guiding section 112 gradually increases along the extension direction from the first side 101 to the second side 102, the cross-sectional area of the inlet of the liquid guiding section 112 is smaller than the cross-sectional area of the drainage outlet 1102. As an example, the aperture ratio of the liquid guiding section 112 is in the range of 1:1 to 1:5. In the case where the cross-sectional shape of the inlet and outlet of the liquid guiding section 112 is circular, the ratio of the diameter of the inlet of the liquid guiding section 112 to the diameter of the outlet is in the range of 1:1 to 1:5. In this way, the enlarged drainage outlet 1102 of the liquid guiding section 112 can reduce the flow rate of the atomized substrate, thereby flowing evenly to the surface of the heating element 20, which helps to improve the atomization effect of the heating element 20.

[0056] In other embodiments, the cross-sectional shape of the liquid discharge outlet 1102 of the liquid guiding section 112 may also be rectangular, square, or diamond-shaped, and the ratio of the length of one side of the inlet of the liquid guiding section 112 to the length of the corresponding side of the liquid discharge outlet 1102 is in the range of 1:1 to 1:5.

[0057] In some embodiments, as Figure 5As shown, the length of the liquid-locking section 111 in the extension direction is equal to the length of the liquid-conducting section 112 in the extension direction. In this way, the liquid-locking section 111 and the liquid-conducting section 112 form two symmetrical funnel-shaped structures. The atomizer core 100 can not only improve the liquid-locking ability of the through hole 11 through the liquid-locking section 111, but also improve the uniformity of the flow of the atomized matrix to the surface of the heating element 20 through the liquid-conducting section 112.

[0058] The following will be combined Figure 6 The structure and combination of the atomizer core 100 of the fourth embodiment of the present disclosure are described in detail. Figure 5 A part of the structure of the third embodiment described is similar. In the following, the differences between them will be mainly described, and the same parts will not be repeated.

[0059] like Figure 6 As shown, the liquid guiding section 112 is arranged downstream of the liquid locking section 111. The atomized matrix in the liquid storage chamber enters the liquid locking section 111 along the through hole 11, and then enters the liquid guiding section 112 from the liquid locking section 111. The liquid locking section 111 can increase the liquid storage amount of the atomized matrix in the through hole 11, thereby improving the atomization effect. The cross-sectional area of the liquid guiding section 112 gradually increases along the extension direction. The length of the liquid locking section 111 in the extension direction may be greater than the length of the liquid guiding section 112 in the extension direction. For example, the ratio of the length of the liquid locking section 111 in the extension direction to the length of the liquid guiding section 112 in the extension direction may be in the range of 10:1 to 1:1. In this way, the liquid level height of the atomized matrix can be adjusted according to the performance of the atomized matrix, thereby realizing the functional adjustment of liquid storage and liquid supply in the through hole 11.

[0060] As an example, for a high-viscosity atomized substrate, the length of the liquid-locking section 111 in the extension direction can be less than or equal to the length of the liquid-conducting section 112 in the extension direction. High-viscosity liquids have poor fluidity, and shortening the length of the liquid-locking section 111 helps reduce resistance in the fluid transmission path, thereby allowing the high-viscosity atomized substrate to be promptly delivered to the heating element 20 for heating and atomization.

[0061] As an example, for a low-viscosity atomized substrate, the length of the liquid-locking section 111 in the extension direction is greater than the length of the liquid-conducting section 112 in the extension direction. Low-viscosity liquids have good fluidity and can flow quickly through the through-hole 11. By increasing the length of the liquid-locking section 111, the liquid storage capacity of the liquid-locking section 111 can be utilized to control the supply speed of the atomized substrate, preventing the atomized substrate from overflowing due to excessive flow rate.

[0062] The following will be combined Figure 7 The structure and combination of the atomizer core 100 of the fifth embodiment of the present disclosure are described in detail. Figures 1 to 3A part of the structure of the first embodiment described is similar. In the following, the differences between them will be mainly described, and the same parts will not be repeated.

[0063] like Figure 7 As shown, each through hole 11 further includes a liquid conducting section 112. The liquid conducting section 112 is disposed upstream of the liquid locking section 111. That is, the liquid inlet 1101 of the through hole 11 is the opening of the liquid conducting section 112 on the first side 101, and the liquid outlet 1102 is the opening of the liquid locking section 111 on the second side 102. The atomized substrate in the liquid storage chamber flows along the through hole 11 into the liquid conducting section 112, and then enters the liquid locking section 111 from the liquid conducting section 112.

[0064] like Figure 7 As shown, the cross-sectional area of the liquid-conducting section 112 gradually increases along the extension direction. In this way, the liquid-conducting section 112 and the liquid-locking section 111 can form an expanded liquid storage area in the middle of the through-hole 11, thereby increasing the liquid storage capacity of the through-hole 11. The cross-sectional area of the liquid-locking section 111 near the outlet of the second side 102 is smaller, which can utilize capillary action to stably transport the atomized substrate to the heating element 20.

[0065] The following will be combined Figure 8 The structure and combination of the atomizer core 100 of the sixth embodiment of the present disclosure are described in detail. Figure 7 The structure of the fifth embodiment is similar in part. Hereinafter, the differences between them will be mainly described, and the same parts will not be repeated.

[0066] like Figure 8 As shown, each through hole 11 also includes a liquid conducting section 112. The liquid conducting section 112 is arranged upstream of the liquid locking section 111. The atomized matrix in the liquid storage tank enters the liquid conducting section 112 along the through hole 11, and then enters the liquid locking section 111 from the liquid conducting section 112. The length of the liquid locking section 111 in the extension direction is less than or equal to the length of the liquid conducting section 112 in the extension direction. For example, the ratio of the length of the liquid locking section 111 in the extension direction to the length of the liquid conducting section 112 in the extension direction can be set to a range of 1:1 to 1:10. In this way, the cross-sectional area of the liquid conducting section 112 gradually increases along the extension direction, and an expanded liquid storage space can be formed, thereby increasing the liquid storage capacity inside the through hole 11. At the same time, the oil supply path of the atomized matrix from the liquid storage tank 301 to the heating element 20 can also be shortened, so that the atomized matrix can quickly reach the heating area, for example, it is suitable for a high-viscosity atomized matrix.

[0067] In one embodiment, the heating element 20 can also be coupled to the first side 101 of the substrate 10. In this arrangement, the heating element 20 directly contacts the atomized substrate in the oil storage tank 301. When the heating element 20 is powered on, it not only heats the atomized substrate about to enter the through-hole 11, but also preheats the entire atomized substrate near the first side 101.

[0068] This preheating brings significant technical advantages. First, it can effectively reduce the viscosity of the atomized matrix, especially for some high-viscosity atomized matrices. Reducing the viscosity can significantly enhance its fluidity, thereby passing through the liquid locking section 111 and the liquid guiding section 112 of the through hole 11 more quickly and smoothly, ensuring the efficiency of liquid supply to the atomization area and effectively avoiding the risk of dry burning caused by poor liquid supply. Secondly, the temperature of the preheated atomized matrix increases, which reduces the energy required to be absorbed when it is thoroughly atomized later, thereby speeding up the overall atomization response speed.

[0069] In some embodiments, the heating element may be arranged on both the first side 101 and the second side 102. For example, the atomizer core may include a first heating element and a second heating element. The first heating element is coupled to the first side 101 of the substrate 10, while the second heating element is coupled to the second side 102 of the substrate 10.

[0070] This collaborative working mode of double-sided heating can bring more outstanding technical effects. Efficient heating in stages: The first heating element acts as a preheating module, responsible for heating the atomized matrix to a preset temperature, effectively reducing its viscosity and preparing for final atomization. Subsequently, the atomized matrix with better fluidity enters the through-hole 11 and reaches the second side 102, where the second heating element, which serves as the main atomization module, performs the final heating and atomization. This division of labor makes the heating process more efficient and improves energy utilization.

[0071] Because the atomized matrix is fully preheated before reaching the primary atomization zone, the secondary heating element can focus more on providing the heat required for phase transition, making the atomization process more intense and complete. This produces a richer, fuller vapor and allows the flavor components in the atomized matrix to be more fully resolved, resulting in an unparalleled taste and richness.

[0072] The dual heating elements can be activated simultaneously or sequentially, and through precise power management, "instant atomization" can be achieved with almost no waiting. In scenarios where large vapor volumes are required, the two heating elements operate simultaneously at high power, providing powerful bursts of power to meet the user's pursuit of performance.

[0073] By arranging the heating elements 20 on different sides or both sides of the substrate 10 at the same time, the technical solution provided by the present disclosure is not limited to the original liquid guidance and liquid locking through structural optimization, but also greatly improves the adaptability of the atomizer core to liquids of different viscosities, atomization efficiency and user experience from the dimension of thermal management, demonstrating a high degree of design flexibility and performance advantages.

[0074] The present disclosure also provides an atomizing device 300. Figure 9 As shown, the atomizing device 300 includes a housing and any of the above-mentioned atomizing cores 100. The housing includes a liquid storage tank 301. The atomizing core 100 is fixed in the housing, and the first side 101 of the atomizing core 100 faces the liquid discharge port of the liquid storage tank 301.

[0075] In the atomizer core 100 of the atomizer device 300, the liquid-locking section 111 can increase the amount of liquid stored in the atomized substrate within the through-hole 11, thereby improving the supply capacity of the atomized substrate. Furthermore, the cross-sectional area of the end of the liquid-locking section 111 near the second side 102 is smaller. This not only draws the atomized substrate closer to the second side 102 through capillary force, but also increases the flow resistance of the atomized substrate, thereby increasing the liquid-locking capacity of the through-hole 11 and reducing the risk of leakage.
