Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomizing core, atomizer, and aerosol generating device. Background Technology

[0002] Aerosol generating devices typically include an atomizer and a power supply component electrically connected to the atomizer. Driven by the power supply component, the atomizer heats and atomizes the aerosol generating matrix stored in the reservoir, forming an aerosol for the user. The heating element usually includes a substrate and a heating element, with the heating element positioned on the atomization surface of the substrate. Electrodes connecting to the power supply circuit are located on both sides of the heating element on the atomization surface of the heating element. The power supply is generally located below the heating element. For aerosol generating devices with the atomization surface facing the mouthpiece, related technologies suffer from low assembly yield of the atomizer core or leakage issues, thus reducing the reliability of the atomizer core. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide an atomizing core, an atomizer, and an aerosol generating device, which is beneficial to improving the reliability of electrical connections, especially improving the reliability of the electrical connection of the atomizing core of the upward atomizing aerosol generating device.

[0004] Therefore, a first aspect of the embodiments of this application provides an atomizing core for use in an atomizer, comprising:

[0005] The substrate includes a liquid-absorbing surface, an atomizing surface, and a perforation. The two ends of the perforation penetrate the atomizing surface and the liquid-absorbing surface, respectively. The substrate is used to guide the aerosol generation matrix from the liquid-absorbing surface to the atomizing surface.

[0006] A heating element is disposed on the atomizing surface, and the heating element includes at least one elastic portion, the elastic portion corresponding to the perforation;

[0007] An electrical connector is provided through the through hole, one end of which is electrically connected to the elastic part, and the other end is used to be electrically connected to the atomizer's pin.

[0008] In some embodiments, the heating element is an integrally formed metal sheet, the heating element includes a heating part and two electrode parts, both of which are connected to the heating part, and each electrode part has at least one elastic part.

[0009] In some embodiments, the elastic portion is constructed by hollowing out a portion of the electrode portion.

[0010] In some embodiments, the projection of the elastic portion onto the atomizing surface overlaps with the projection of the perforation.

[0011] In some embodiments, the maximum size of the projection of the perforation onto the atomizing surface is in the range of 0.5 mm to 5 mm.

[0012] In some embodiments, the heating element includes a clearance hole, one end of the elastic portion is connected to the wall of the clearance hole, and the other end extends toward the center of the clearance hole.

[0013] In some embodiments, the projection of the perforation is located within the projection range of the avoidance hole on the atomizing surface.

[0014] In some embodiments, at least a portion of the elastic portion extends along a curve in the direction from the wall of the clearance hole to the center of the clearance hole.

[0015] In some embodiments, each of the clearance holes corresponds to a plurality of the elastic portions, and the elastic portions are arranged at circumferential intervals along the clearance hole.

[0016] In some embodiments, the size of the electrical connector is greater than or equal to the size of the substrate along the direction from the liquid absorption surface to the atomizing surface.

[0017] In some embodiments, the electrical connector has a connecting portion at one end near the liquid-absorbing surface, which projects onto the liquid-absorbing surface. The maximum size of the projection of the connecting portion is greater than the maximum size of the projection of the perforation.

[0018] In some embodiments, the electrical connector protrudes from the atomizing surface, or the electrical connector is flush with the atomizing surface.

[0019] In some embodiments, the height difference between the electrical connector and the atomizing surface is in the range of 0 to 0.5 mm.

[0020] In some embodiments, the atomizing core further includes a seal for sealing the gap between the electrical connector and the wall of the perforation.

[0021] In some embodiments, the seal fills the gap between the circumferential sidewall of the electrical connector and the wall of the perforation.

[0022] In some embodiments, the electrical connector has a sealing element around at least one end along the direction from the liquid-absorbing surface to the atomizing surface.

[0023] In some embodiments, the heating element is provided with multiple openings, and the atomizing core further includes an adhesive layer. The heating element and the atomizing surface are bonded together by the adhesive layer, and at least a portion of the adhesive layer fills the openings.

[0024] In some embodiments, the heating element includes a plurality of heating wires and a plurality of fixed rings located on both sides of the plurality of heating wires, and the opening is disposed in the fixed rings.

[0025] A second aspect of this application provides an atomizer, comprising:

[0026] The nozzle end;

[0027] The bottom end is opposite to the nozzle end;

[0028] The atomizing core described above has its atomizing surface facing the mouthpiece end;

[0029] The ejector pin is located between the atomizing core and the bottom end, and the ejector pin is electrically connected to the electrical connector.

[0030] In some embodiments, the ejector pin directly or indirectly abuts against the electrical connector.

[0031] A second aspect of this application provides an aerosol generating apparatus, including a power supply component and the atomizer described above, wherein the power supply component is electrically connected to the pin of the atomizer.

[0032] The atomizing core substrate provided in this embodiment has perforations, with the atomizing surface and the liquid absorption surface penetrating through the two ends of the perforations respectively. Electrical connectors are inserted through these perforations. This allows the atomizer's ejector pin to be positioned on one side of the liquid absorption surface for electrical connection with the heating element. In other words, by aligning the atomizing surface towards the exhaust channel, the aerosol-generating matrix can be directly released into the exhaust channel by the atomized aerosol without needing to be turned, thus reducing aerosol loss and improving atomization efficiency. Furthermore, by including at least one elastic portion in the heating element, a certain tolerance is allowed when the electrical connector is electrically connected to the elastic portion. This allows for release through elastic deformation of the elastic portion, mitigating situations where the electrical connector pushes the heating element away from the atomizing surface due to manufacturing tolerances or assembly issues. This improves the assembly yield between the electrical connector and the heating element, as well as the assembly efficiency of the atomizing core, thereby enhancing the reliability of the atomizing core.

[0042] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0043] In the description of the embodiments in this application, it should be noted that the terms "top," "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 and attached Figure 3 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to 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 limiting the embodiments of this application. The application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] One aspect of this application provides an aerosol generating apparatus 1000. Please refer to [link to relevant documentation]. Figures 1 to 3 The aerosol generating device 1000 includes a power supply assembly 200 and an atomizer 100 provided in any embodiment of this application. The power supply assembly 200 is electrically connected to the ejector pin 20 of the atomizer 100.

[0045] In some embodiments, the atomizer 100 and the power supply assembly 200 can be mechanically and electrically connected together axially. Further, the atomizer 100 and the power supply assembly 200 can be connected together in a detachable manner using magnetic connections, threaded connections, snap-fit ​​connections, or other similar methods. Both the atomizer 100 and the power supply assembly 200 can be replaced or upgraded individually, reducing replacement costs and saving user expenses. Of course, in other embodiments, the atomizer 100 and the power supply assembly 200 can also be connected together in a non-detachable manner.

[0046] Furthermore, the atomizer 100 and / or power assembly 200 are not limited to being cylindrical; they can also be other shapes such as elliptical cylinders, square boxes, or polygonal cylinders. For example, in this embodiment, the cross-section at the lower end of the atomizer 100 is approximately elliptical, while the cross-section at the upper part of the atomizer 100 is approximately flat.

[0047] It should be noted that the specific type of the aerosol generating device 1000 provided in this application embodiment is not limited. For example, the aerosol generating device 1000 can be a medical nebulizer, an air humidifier, or an electronic cigarette or other nebulizer.

[0048] One aspect of this application provides an atomizer 100; please refer to... Figures 2 to 5 The atomizer 100 includes a mouthpiece end 50, a bottom end 60, an atomizing coil 10, and a tip pin 20. The bottom end 60 is opposite to the mouthpiece end 50. The atomizing surface 112 faces the mouthpiece end 50. The tip pin 20 is located between the atomizing coil 10 and the bottom end 60. The tip pin 20 is electrically connected to the electrical connector 13.

[0049] For example, the ejector pin 20 directly or indirectly abuts against the electrical connector 13 to achieve an electrical connection between the ejector pin 20 and the electrical connector 13.

[0050] One aspect of this application provides an atomizing core 10; please refer to... Figures 4 to 7 The atomizing core 10 includes a substrate 11, a heating element 12, and an electrical connector 13. The substrate 11 includes a liquid-absorbing surface 111, an atomizing surface 112, and a perforation 113, with both ends of the perforation 113 penetrating the atomizing surface 112 and the liquid-absorbing surface 111, respectively. The substrate 11 guides the aerosol-generating matrix from the liquid-absorbing surface 111 to the atomizing surface 112. The heating element 12 is disposed on the atomizing surface 112 and includes at least one elastic portion 121. The elastic portion 121 corresponds to the perforation 113. The electrical connector 13 passes through the perforation 113, with one end electrically connected to the elastic portion 121 and the other end electrically connected to the pin 20 of the atomizer 100.

[0051] For example, the mouthpiece end 50 refers to the end of the atomizer 100 closest to the user when using the aerosol generating device 1000, and the bottom end 60 refers to the end of the atomizer 100 furthest from the user when using the aerosol generating device 1000. For example, please refer to... Figure 2 and Figure 3 The mouthpiece end 50 is the top of the atomizer 100, and the bottom end 60 is the bottom of the atomizer 100.

[0052] Here, the atomizing surface 112 of the atomizing core 10 faces the mouthpiece end 50 (the atomizing core 10 atomizes upwards). In other words, the aerosol generated by the atomizing surface 112 atomizing the aerosol generation matrix can flow directly to the mouthpiece end 50. The aerosol does not need to bend before finally reaching the user. This reduces aerosol loss and improves the flavor explosion and atomization efficiency.

[0053] For example, the atomizer 100 includes an air outlet channel 30 for discharging the aerosol generated by the atomizing core 10.

[0054] For example, the atomizer 100 also includes a liquid storage chamber 40 for storing the aerosol generation matrix, and the liquid storage chamber 40 is in liquid communication with the liquid absorption surface 111. That is, the aerosol generation matrix in the liquid storage chamber 40 is guided to the atomizing surface 112 through the liquid absorption surface 111, and the heating element 12 atomizes the aerosol generation matrix to generate aerosol. The aerosol generated during heating and atomization is guided by the upward airflow and directly discharged through the air outlet channel 30 and drawn in by the user, reducing the loss caused by aerosol deflection.

[0055] For example, the atomizer 100 also includes a ventilation channel. The aerosol generating matrix in the liquid storage chamber 40 is atomized by the atomizing core 10 to generate aerosol. After the aerosol generating matrix in the liquid storage chamber 40 is consumed, external gas enters the liquid storage chamber 40 through the ventilation channel to balance the pressure in the liquid storage chamber 40.

[0056] The atomizing core 10 includes a heating element 12, which generates heat to heat and atomize the aerosol generating matrix.

[0057] It should be noted that the specific structure of the heating element 12 is not limited here. The heating element 12 may include, but is not limited to, heating sheets, heating films, heating meshes, etc.

[0058] The specific shape of the heating element 12 is not limited here. The heating element 12 may be flat, cylindrical, or bowl-shaped.

[0059] For example, please refer to Figure 3The atomizer 100 is provided with an air outlet tube that extends along the height of the atomizer 100, and an air outlet channel 30 is formed inside the air outlet tube. One end of the air outlet of the air outlet channel 30 (the end of the air outlet channel 30 away from the atomizing core) is the mouthpiece end 50.

[0060] In some embodiments, the atomizer 100 includes a mouthpiece disposed at the end of the air outlet tube away from the atomizing core 10, through which the user inhales the aerosol discharged through the air outlet channel 30. The end of the atomizer 100 with the mouthpiece is the mouthpiece end 50.

[0061] Of course, in other embodiments, the atomizer 100 may not have a mouthpiece.

[0062] For example, the heating element 12 includes at least one elastic part 121, which is similar to a buffer structure and has a certain elasticity.

[0063] The heating element 12 includes at least one elastic part 121, meaning that the heating element 12 may include one elastic part 121 or multiple elastic parts 121.

[0064] In the embodiments of this application, "multiple" refers to two or more items.

[0065] For example, the heating element 12 includes a heating part 126 and an electrode part 125. The electrode part 125 is used to electrically connect with the ejector pin 20 and includes an elastic part 121.

[0066] For example, there are two electrode portions 125, which are disposed at opposite ends of the heating portion 126.

[0067] For example, the heating element 12 is an integrally formed metal sheet. The heating element 12 includes a heating part 126 and two electrode parts 125. Both electrode parts 125 are connected to the heating part 126, and each electrode part 125 has at least one elastic part.

[0068] Each electrode portion 125 may be provided with one elastic portion 121 or multiple elastic portions 121.

[0069] Since the heating element 12 is a one-piece molded metal sheet, it helps to reduce the number of parts, improve the assembly efficiency of the atomizing core 10, and also improve the reliability of the heating element 12.

[0070] For example, the elastic portion 121 is constructed by hollowing out a portion of the electrode portion 125.

[0071] In other words, by hollowing out a portion of the electrode portion 125 to form the elastic portion 121, the elastic portion 121 and the electrode portion 125 are integrally formed, thereby improving the overall structural strength of the heating element 12.

[0072] For example, the substrate 11 may be a ceramic body.

[0073] It is understandable that in embodiments where the atomizing surface 112 of the atomizing core 10 faces the mouthpiece end 50 (the atomizing core 10 atomizes upwards), during the process of the electrical connector 13 passing through the substrate 11 and electrically connecting to the heating element 12 (such as mesh, thick film, thin film, etc.), due to the tolerances in the processing technology of the substrate 11, the ejector pin 20, the electrical connector 13 and / or the heating element 12, and the tolerances in the bonding process of the heating element 12, the overall system tolerance is large. This results in the difficulty of tightly assembling the electrical connector 13 and the heating element 12, and the possibility that the heating element 12 may be pushed out of the atomizing surface 112 by the electrical connector 13 or the bonding force may be poor. This leads to a low yield rate in the assembly between the electrical connector 13 and the heating element 12, and the failure of the atomizing core 10.

[0074] By configuring the heating element 12 to include at least one elastic part 121, and the elastic part 121 having a certain elasticity, a certain tolerance is allowed when the electrical connector 13 passes through the base 11 and is electrically connected to the elastic part 121. That is, the tolerance can be released by the elastic deformation of the elastic part 121, thereby improving the assembly yield between the electrical connector 13 and the heating element 12, that is, improving the stability of the electrical connection of the atomizing core 10, and thus improving the reliability of the atomizing core 10.

[0075] In the aerosol generating device 1000, the power supply component 200 is electrically connected to the atomizer 100 by direct contact with the pin 20. When the atomizing surface 112 faces the mouthpiece end 50, in related technologies, the atomizing surface 112 electrode is reached by using a non-standard electrical connector 13 that bypasses the substrate 11 from the side of the substrate 11. This may result in poor sealing of the atomizing core 10, which may lead to the possibility of air or liquid leakage.

[0076] The atomizing core 10 provided in this embodiment has a perforation 113, with the two ends of the perforation 113 penetrating the atomizing surface 112 and the liquid absorption surface 111, respectively. The electrical connector 13 is inserted through the perforation 113. In this way, the pin 20 of the atomizer 100 can be set on one side of the liquid absorption surface 111 to achieve electrical connection with the heating element 12. That is, by setting the atomizing surface 112 toward the mouthpiece end 50, the aerosol generating matrix can be directly released into the air outlet channel 30 by the atomized aerosol without turning, which helps to reduce aerosol loss, improve the flavor burst and atomization efficiency. Furthermore, by configuring the heating element 12 to include at least one elastic portion 121, and the elastic portion 121 having a certain elasticity, a certain tolerance is allowed when the electrical connector 13 is electrically connected to the elastic portion 121. That is, the elastic portion 121 can be released through elastic deformation. This helps to improve the situation where the electrical connector 13 pushes the heating element 12 away from the atomizing surface 112 due to manufacturing tolerances or assembly. This can improve the assembly yield between the electrical connector 13 and the heating element 12 and the assembly efficiency of the atomizing core 10, that is, improve the stability of the electrical connection of the atomizing core 10, and thus improve the reliability of the atomizing core 10.

[0077] In some embodiments, please refer to Figures 4 to 6 When projected onto the atomizing surface 112, the projection of the elastic part 121 overlaps with the projection of the perforation 113.

[0078] In other words, at least a portion of the structure of the elastic part 121 extends above the perforation 113 to facilitate contact with the electrical connector 13.

[0079] For example, when projected onto the atomizing surface 112, the projection of the elastic part 121 overlaps with the projection of the electrical connector 13 to achieve an electrical connection between the electrical connector 13 and the elastic part 121.

[0080] For example, the electrical connector 13 may be columnar, with the columnar electrical connector 13 passing through the base 11. The two ends of the electrical connector 13 are electrically connected to the elastic portion 121 located on one side of the atomizing surface 112 and to the ejector pin 20 located on one side of the liquid absorption surface 111, respectively. That is, the electrical connector 13 passes through the base 11 to realize the electrical connection between the heating element 12 and the ejector pin 20, and the heating element 12 is then electrically connected to the power supply assembly 200 through the ejector pin 20.

[0081] For example, the material of the electrical connector 13 may be gold, silver, copper or their alloys, stainless steel alloys, iron-chromium-aluminum alloys, etc.

[0082] In this embodiment, by setting the projection of the elastic part 121 and the projection of the perforation 113 to have an overlapping area, while realizing the electrical connection between the electrical connector 13 and the elastic part 121, that is, at least a part of the structure of the elastic part 121 extends to the top of the perforation 113 and connects with the electrical connector 13, it is beneficial to reduce the molding difficulty of the electrical connector 13 and improve the stability of the electrical connection between the electrical connector 13 and the elastic part 121.

[0083] It should be noted that the cross-sectional shape of the perforation 113 is not limited here. For example, the cross-sectional shape of the perforation 113 can be circular, square, etc., and of course, it can also be other regular or irregular shapes.

[0084] For example, the cross-sectional shape of the perforation 113 is adapted to the shape of the electrical connector 13.

[0085] For example, the cross-sectional shape of the perforation 113 is circular, which is compatible with the existing circular ejector pin 20. This improves the reliability of the electrical connection between the electrical connector 13 and the ejector pin 20, while also improving assembly efficiency.

[0086] In some embodiments, the maximum size of the projection of the perforation 113 onto the atomizing surface 112 is in the range of 0.5 mm to 5 mm.

[0087] The maximum size of the projection of the perforation 113 on the atomizing surface 112 can be 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, 2.7mm, 3mm, 3.5mm, 3.8mm, 4mm, 4.2mm, 4.5mm, 4.8mm, 5mm, etc.

[0088] For example, in an embodiment where the projection of the perforation 113 is circular, the maximum size of the projection of the perforation 113 on the atomizing surface 112 is the aperture of the perforation 113; in an embodiment where the projection of the perforation 113 is rectangular, the maximum size of the projection of the perforation 113 on the atomizing surface 112 is the diagonal of the projection of the perforation 113; and in an embodiment where the projection of the perforation 113 is other irregular shapes, the maximum size of the projection of the perforation 113 on the atomizing surface 112 is the distance between the two farthest points of the projection.

[0089] Here, by setting the maximum size of the projection of the perforation 113 on the atomizing surface 112 to be in the range of 0.5mm to 5mm, the reliability of the electrical connection between the electrical connector 13 and the elastic part 121 and the ejector pin 20 is improved, and to a certain extent, the problem of reduced structural strength of the substrate 11 due to excessively large perforations 113 is also improved.

[0090] It should be noted that the elastic part 121 can have various structural forms, as long as it can produce elastic deformation.

[0091] In some embodiments, please refer to Figures 4 to 5 The heating element 12 includes a clearance hole 124, one end of the elastic part 121 is connected to the hole wall of the clearance hole 124, and the other end extends toward the center of the clearance hole 124.

[0092] In other words, the elastic portion 121 extends toward the center of the clearance hole 124 to form an elastic cantilever.

[0093] The specific forming method of the heating element 12 is not limited here. For example, the heating element 12 can be formed by cutting a metal sheet.

[0094] For example, the heating element 12 may be formed by hollowing out to create a clearance hole 124.

[0095] Here, by connecting one end of the elastic part 121 to the wall of the clearance hole 124 and extending the other end toward the center of the clearance hole 124, a cantilever structure is formed, which facilitates the elastic deformation of the electrical connector 13 when it is electrically connected to the elastic part 121, thereby improving the connection reliability between the electrical connector 13 and the elastic part 121.

[0096] For example, the width of the elastic part 121 is in the range of 0.1 mm to 1 mm, so that the elastic part 121 has a certain elasticity while also having a certain structural strength.

[0097] For example, the thickness of the elastic portion 121 is the same as the thickness of the other regions of the heating element 12 excluding the elastic portion 121, which facilitates molding. Of course, the thickness of the elastic portion 121 may also be different from the thickness of the other regions of the heating element 12 excluding the elastic portion 121; for example, the thickness of the elastic portion 121 may be less than the thickness of the other regions of the heating element 12 excluding the elastic portion 121.

[0098] For example, the length of the elastic portion 121 does not exceed the size of the clearance hole 124.

[0099] For example, one end of the elastic part 121 is connected to the wall of the clearance hole 124, and the other end is a free end.

[0100] In some embodiments, please refer to Figure 7 At least a portion of the elastic portion 121 extends along a curve in the direction from the wall of the clearance hole 124 to the center of the clearance hole 124.

[0101] The phrase "at least a portion of the elastic part 121 extends along a curve" means that the elastic part 121 may have a portion that is curved and another portion that is straight. Alternatively, the elastic part 121 may have a whole region that is curved.

[0102] In other words, the elastic part 121 can be curved or a combination of curved and straight types.

[0103] It is understandable that different shapes of the elastic part 121 result in different elastic deformations. With the same width, length and thickness, setting at least a portion of the elastic part 121 to extend along a curve can improve the elastic deformation of the elastic part 121, thereby further improving the connection reliability between the electrical connector 13 and the elastic part 121.

[0104] Here, the elastic part 121 can be a horizontal cantilever structure or an inclined cantilever structure.

[0105] It should be noted that a horizontal cantilever structure refers to a heating element 12 having a flat plate structure, meaning that the elastic part 121 and other areas of the heating element 12, excluding the elastic part 121, are all located in the same plane. An inclined cantilever structure refers to a structure in which at least a portion of the elastic part 121 is inclined relative to other areas of the heating element 12, excluding the elastic part 121.

[0106] In some embodiments, please refer to Figures 4 to 5 The projection of the perforation 113 is located within the projection range of the clearance hole 124 on the atomizing surface 112.

[0107] In other words, the projected size of the perforation 113 is smaller than the projected size of the clearance hole 124.

[0108] Here, by setting the projection of the perforation 113 to be within the projection range of the clearance hole 124, when assembling the electrical connector 13, it is possible to avoid the electrical connector 13 hitting the area of ​​the heating element 12 other than the elastic part 121. In this way, to a certain extent, it is possible to avoid the situation where the electrical connector 13 pushes the heating element 12 out of the atomizing surface 112, which is conducive to further improving the assembly yield between the electrical connector 13 and the heating element 12.

[0109] In some embodiments, please refer to Figures 4 to 5 Each clearance hole 124 corresponds to multiple elastic parts 121, and each elastic part 121 is arranged at intervals along the circumference of the clearance hole 124.

[0110] For example, the number of clearance holes 124 corresponds one-to-one with the number of electrode portions 125.

[0111] Here, the structure of the elastic part 121 corresponding to each clearance hole 124 can be the same or different.

[0112] For example, each elastic part 121 is uniformly arranged along the circumference of the clearance hole 124.

[0113] In this embodiment, by setting each clearance hole 124 as a corresponding multiple elastic parts 121, and the elastic parts 121 are arranged at intervals along the circumferential direction of the clearance hole 124, it is beneficial to further improve the connection reliability between the electrical connector 13 and the heating element 12.

[0114] In some embodiments, the size of the electrical connector 13 is greater than or equal to the size of the substrate 11 along the direction from the liquid absorption surface 111 to the atomizing surface 112.

[0115] The direction from the liquid absorption surface 111 to the atomizing surface 112 refers to the thickness direction of the substrate 11.

[0116] Along the direction from the liquid absorption surface 111 to the atomizing surface 112, the size of the electrical connector 13 is greater than or equal to the size of the substrate 11. That is, the size of the electrical connector 13 along the direction from the liquid absorption surface 111 to the atomizing surface 112 is greater than or equal to the thickness of the substrate 11.

[0117] Here, along the direction from the liquid absorption surface 111 to the atomizing surface 112, the size of the electrical connector 13 is set to be greater than or equal to the size of the base 11, so that the electrical connector 13 can contact the elastic part 121 and the ejector pin 20.

[0118] In some embodiments, the electrical connector 13 is provided with a connecting portion at one end near the liquid absorption surface 111, which is projected onto the liquid absorption surface 111. The maximum size of the projection of the connecting portion is greater than the maximum size of the projection of the perforation 113.

[0119] Here, by projecting the maximum size of the projection of the connecting part onto the liquid absorption surface 111, which is larger than the maximum size of the projection of the perforation 113, the connecting part can be prevented from extending into the perforation 113, thereby improving the assembly efficiency of the electrical connector 13 and the ejector pin 20 and the reliability of the electrical connection.

[0120] In some embodiments, the electrical connector 13 protrudes from the atomizing surface 112, or the electrical connector 13 is flush with the atomizing surface 112.

[0121] In embodiments where the elastic portion 121 is not inclined toward the perforation 113, if the electrical connector 13 does not protrude from the atomizing surface 112, it is not conducive to the connection between the electrical connector 13 and the elastic portion 121.

[0122] For example, the end face of the electrical connector 13 is higher than the atomizing surface 112 of the substrate 11, but lower than the surface of the heating element 12 on the side opposite to the atomizing surface 112.

[0123] In this embodiment, by having the electrical connector 13 protrude from the atomizing surface 112, or by having the electrical connector 13 flush with the atomizing surface 112, it is beneficial to achieve the connection between the electrical connector 13 and the elastic part 121. Furthermore, the elastic part 121 does not need to be tilted toward the through hole 113, which helps to simplify the structure of the heating element 12 and reduce manufacturing costs.

[0124] In some embodiments, the height difference between the electrical connector 13 and the atomizing surface 112 is in the range of 0 to 0.5 mm.

[0125] In other words, the height of the electrical connector 13 protruding from the atomizing surface 112 can be in the range of 0 to 0.5 mm.

[0126] The height difference between the electrical connector 13 and the atomizing surface 112 can be 0, 0.05mm, 0.1mm, 0.12mm, 0.15mm, 0.18mm, 0.2mm, 0.25mm, 0.28mm, 0.3mm, 0.32mm, 0.35mm, 0.36mm, 0.4mm, 0.45mm, 0.47mm, 0.5mm, etc.

[0127] Here, by setting the height of the electrical connector 13 protruding from the atomizing surface 112 to be in the range of 0 to 0.5 mm, it is not only beneficial to realize the connection between the electrical connector 13 and the elastic part 121, but also to a certain extent to avoid the situation where the electrical connector 13 pushes the heating element 12 out of the atomizing surface 112, which is conducive to further improving the assembly yield between the electrical connector 13 and the heating element 12.

[0128] In some embodiments, please refer to Figures 5 to 6 The atomizing core 10 also includes a seal 14, which is used to seal the gap between the electrical connector 13 and the wall of the perforation 113.

[0129] It should be noted that there are multiple ways in which the seal 14 can be used to seal the gap between the electrical connector 13 and the hole wall of the through hole 113.

[0130] For example, the seal 14 may be a gap filled between the circumferential sidewall of the electrical connector 13 and the wall of the perforation 113.

[0131] This can be achieved by filling the entire gap between the circumferential sidewall of the electrical connector 13 and the hole wall of the perforation 113 with sealing material to form a seal 14; or by filling a portion of the gap between the circumferential sidewall of the electrical connector 13 and the hole wall of the perforation 113 with sealing material to form a seal 14, as long as it can limit the flow of aerosol generation matrix from the gap between the circumferential sidewall of the electrical connector 13 and the hole wall of the perforation 113.

[0132] For example, at least one end of the electrical connector 13 along the direction from the liquid absorption surface 111 to the atomizing surface 112 is provided with a sealing ring 14.

[0133] In other words, the seal 14 can be a single ring only at the end of the electrical connector 13. For example, a single ring of seal 14 can be provided at the end of the electrical connector 13 near the liquid absorption surface 111, or a single ring of seal 14 can be provided at the end of the electrical connector 13 near the atomizing surface 112, or a single ring of seal 14 can be provided at both the end of the electrical connector 13 near the liquid absorption surface 111 and the end near the atomizing surface 112.

[0134] For example, the seal 14 may be a sealing ring or the like.

[0135] For example, the material of the seal 14 may be silicone.

[0136] For example, a sealant may be filled between the circumferential sidewall of the electrical connector 13 and the perforation 113 to form a seal 14.

[0137] Here, the paste can be a conductive paste, a glass paste, etc.

[0138] In this embodiment, by filling the gap between the circumferential sidewall of the electrical connector 13 and the perforation 113 with a sealant 14 to seal the gap between the circumferential sidewall of the electrical connector 13 and the perforation 113, the flow of aerosol generation matrix from the gap between the circumferential sidewall of the electrical connector 13 and the perforation 113 can be improved, which is beneficial to improving the sealing performance of the atomizing core 10.

[0139] In some embodiments, the heating element 12 is provided with a plurality of openings, and the atomizing core 10 further includes an adhesive layer. The heating element 12 and the atomizing surface 112 are bonded together by the adhesive layer, and at least part of the adhesive layer fills the openings.

[0140] The heating element 12 is bonded to the atomizing surface 112 through an adhesive layer. In other words, the heating element 12 is bonded to the substrate 11 through an adhesive layer, and the connection structure is simple and reliable.

[0141] For example, the electrode portion 125 may be provided with a plurality of openings, the openings surrounding the periphery of the elastic portion 121, that is, the openings surrounding the periphery of the clearance hole 124.

[0142] For example, the opening can be a blind hole, that is, the opening does not penetrate the heating element 12, or it can be a through hole 113, that is, the opening penetrates the heating element 12.

[0143] In embodiments where the opening is a blind hole, it can be an opening formed by a recess on the side of the heating element 12 facing the atomizing surface 112.

[0144] Here, by providing multiple openings in the heating element 12, when the heating element 12 and the atomizing surface 112 are bonded together by the adhesive layer, the adhesive material penetrates into the openings, forming a rivet-like effect between the heating element 12 and the substrate 11, thereby improving the bonding force between the heating element 12 and the substrate 11.

[0145] In some embodiments, the heating element 126 includes a plurality of heating wires 1261 and a plurality of fixed rings 1262 located on both sides of the plurality of heating wires 1261, with openings provided in the fixed rings 1262.

[0146] Because retaining rings 1262 are provided on both sides of the heating wire 1261, it is beneficial to improve the bonding force between the heating element 126 and the substrate, thereby improving the bonding force between the heating element 12 and the substrate 11. Furthermore, by providing openings in the retaining rings 1262, the bonding force between the heating element 12 and the substrate 11 is further improved. In other embodiments, the heating element 12 and the substrate 11 are integrally formed. This helps reduce the number of parts, improves assembly efficiency, and simultaneously enhances the bonding force between the heating element 12 and the substrate 11.

[0147] The following is a brief description of two specific embodiments with reference to the accompanying drawings.

[0152] For example, a ceramic substrate 11 and a heating element 12 are integrally formed by sintering a ceramic green body and a heating element 12 together. The heating element 12 has a clearance hole 124 with an elastic portion 121.

An electrical connector 13 is assembled into the through hole 113, and a sealing material, such as a conductive paste or glass paste, is filled into the gap between the through hole 113 and the electrical connector 13. The sealing material is then sintered and cured to form a sealant 14.
