[0038] 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 conductive element 20 of the atomizer 100.
[0039] 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.
[0040] 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.
[0041] It should be noted that the specific type of the aerosol generating device 1000 provided by the embodiments of the present application is not limited. For example, the aerosol generating device 1000 can be a medical atomization equipment, can also be an air humidifier, and can also be an electronic cigarette or other atomization equipment.
[0042] In an aspect, the present application provides an atomizer 100, please refer to Figures 3 to 6 The atomizer 100 includes a mouth end 50, a bottom end 60, an atomizing core 10, and a conductive piece 20. The bottom end 60 is opposite to the mouth end 50. An atomizing surface 112 faces the mouth end 50. The mouth end 50 is located between the atomizing core 10 and the bottom end 60. The conductive piece 20 is electrically connected with an electrical connector 13.
[0043] For example, the conductive piece 20 can be a needle or an elastic sheet.
[0044] For example, the conductive piece 20 directly or indirectly abuts against the electrical connector 13 to achieve electrical connection between the conductive piece 20 and the electrical connector 13.
[0045] In an aspect, the present application provides an atomizing core 10, please refer to Figures 4 to 9 The atomizing core 10 includes a base 11, a heating piece 12, and an electrical connector 13. The base 11 includes a liquid absorbing surface 111, an atomizing surface 112, and at least two perforations 113, both ends of each perforation 113 penetrating through the atomizing surface 112 and the liquid absorbing surface 111 respectively. The base 11 is used to guide the aerosol generating substrate from the liquid absorbing surface 111 to the atomizing surface 112. The heating piece 12 is arranged on the atomizing surface 112. The heating piece 12 includes a heating portion 126 and electrode portions 125 located at both ends of the heating portion 126, and each electrode portion 125 corresponds to a perforation 113. Each electrode portion 125 includes a fixed portion 121 corresponding to the perforation 113. The electrical connector 13 is arranged in the perforation 113. The electrical connector 13 and the fixed portion 121 are in an integral structure.
[0046] An end of the electrical connector 13 away from the heating piece 12 is used to electrically connect with the conductive piece 20 of the atomizer 100.
[0047] For example, the mouth end 50 refers to an end of the atomizer 100 close to a user when the user uses the aerosol generating device 1000, and the bottom end 60 refers to an end of the atomizer 100 away from the user when the user uses the aerosol generating device 1000.
[0048] For example, please refer to Figure 2 and Figure 3 The mouth end 50 is the top end of the atomizer 100, and the bottom end 60 is the bottom end of the atomizer 100.
[0049] Here, the atomization face 112 of the atomization core 10 faces the mouth end 50 (the atomization core 10 atomizes upward), that is, the aerosol generated by the atomization of the aerosol generating substrate by the atomization face 112 can directly flow to the mouth end 50, and the aerosol does not need to be bent to finally reach the user, thereby the aerosol loss can be reduced, and the mouthfeel explosion and atomization efficiency can be improved.
[0050] Exemplarily, the atomizer 100 comprises an air outlet channel 30 for discharging the aerosol atomized by the atomization core 10.
[0051] Exemplarily, the atomizer 100 further comprises a liquid storage cavity 40 for storing the aerosol generating substrate, and the liquid storage cavity 40 is in liquid communication with the liquid suction face 111. That is, the aerosol generating substrate in the liquid storage cavity 40 is guided to the atomization face 112 through the liquid suction face 111, and the aerosol generating substrate is atomized by the heating element 12 to generate aerosol, and the aerosol generated during heating and atomization is guided by the upward airflow and directly discharged through the air outlet channel 30 to be inhaled by the user, thereby reducing the loss caused by the diversion of the aerosol.
[0052] Exemplarily, the atomizer 100 further comprises an air exchange channel, the aerosol generating substrate in the liquid storage cavity 40 is atomized by the atomization core 10 to generate aerosol, and after the aerosol generating substrate in the liquid storage cavity 40 is consumed, external gas enters the liquid storage cavity 40 through the air exchange channel to balance the pressure in the liquid storage cavity 40.
[0053] Exemplarily, as shown in Figure 3 , the atomization face 112 faces the air outlet channel 30, that is, the atomization face 112 faces the top.
[0054] The atomization core 10 comprises a heating element 12, and the heating element 12 generates heat to heat and atomize the aerosol generating substrate.
[0055] It should be noted that the specific structure of the heating element 12 is not limited herein, and the heating element 12 includes but is not limited to a heating sheet, a heating film, a heating net, etc.
[0056] The specific shape of the heating element 12 is not limited herein, and the heating element 12 includes but is not limited to a flat plate, a cylinder, a bowl-like shape, etc.
[0057] Exemplarily, referring to Figure 3 , the atomizer 100 is provided with an air outlet tube extending along the height direction of the atomizer 100, and the air outlet tube forms the air outlet channel 30 inside. One end of the air outlet of the air outlet channel 30 (the end of the air outlet channel 30 away from the atomization core) is the mouth end 50.
[0058] In some embodiments, the atomizer 100 comprises a suction nozzle arranged at the end of the air outlet tube away from the atomizing core 10, and the user inhales the aerosol discharged through the air outlet channel 30 through the suction nozzle. The end of the atomizer 100 provided with the suction nozzle is the suction nozzle end 50.
[0059] Of course, in other embodiments, the atomizer 100 can also be provided without a suction nozzle.
[0060] Exemplarily, the base body 11 can be a ceramic body.
[0061] Here, by adopting the one-piece structure of the electric connecting piece 13 and the fixing part 121, the bonding force between the electric connecting piece 13 and the heating piece 12 can be improved, and the electric connecting piece 13 is not easy to be separated from the heating piece 12. In addition, it is beneficial to reduce the number of components, thereby improving the assembly efficiency. Furthermore, it can also improve the situation that the electric connecting piece 13 pushes the heating piece 12 away from the atomizing surface 112 due to manufacturing tolerance or assembly.
[0062] In the aerosol-generating device 1000, the electrically conductive piece 20 of the atomizer 100 is directly in contact with the power supply assembly 200 to achieve electrical connection. In the related art, by adopting the special-shaped electric connecting piece 13 to bypass the base body 11 from the side of the base body 11 to reach the atomizing surface 112 electrode, it can cause poor sealing of the atomizing core 10, thereby possibly causing the possibility of air and liquid leakage.
[0063] The base body 11 of the atomizing core 10 provided by the embodiments of the present application is provided with a perforation 113, the two ends of the perforation 113 respectively penetrate the atomizing surface 112 and the liquid suction surface 111, and the electric connecting piece 13 is arranged in the perforation 113. In this way, the electrically conductive piece 20 of the atomizer 100 can be arranged on one side of the liquid suction surface 111 to achieve electrical connection with the heating piece 12. That is, the atomizing surface 112 can be arranged to face the suction nozzle end 50, so that the aerosol generated by the aerosol-generating substrate is directly released to the suction nozzle end 50 without turning, which is beneficial to reduce the loss of aerosol and improve the atomization efficiency. In addition, by adopting the one-piece structure of the electric connecting piece 13 and the fixing part 121, it is beneficial to improve the situation that the electric connecting piece 13 pushes the heating piece 12 away from the atomizing surface 112 due to manufacturing tolerance or assembly, thereby improving the assembly yield and assembly efficiency of the atomizing core 10, that is, improving the stability of the electrical connection of the atomizing core 10, and further improving the reliability of the atomizing core 10, especially the reliability of the electrical connection of the atomizing core 10 of the upward atomizing aerosol-generating device 1000.
[0064] Exemplarily, the heating piece 12 comprises a heating part 126 and electrode parts 125 located at both ends of the heating part 126, the electrode parts 125 correspond one-to-one to the perforations 113, and each electrode part 125 comprises a fixing part 121 corresponding to the perforation 113.
[0065] Exemplarily, the heating element 12 is an integrally formed metal sheet, and the fixing portion 121 is partially hollowed out. The fixing portion 121 and the electrical connecting element 13 are sintered and integrally formed.
[0066] Since the heating element 12 is an integrally formed metal sheet, the number of components can be reduced, the assembly efficiency of the atomizing core 10 can be improved, and the reliability of the heating element 12 can also be improved.
[0067] Exemplarily, the fixing portion 121 is configured to be formed by hollowing out part of the electrode portion 125.
[0068] That is, by hollowing out part of the electrode portion 125 to form the fixing portion 121, the integrally formed structure of the fixing portion 121 and the electrode portion 125 is achieved, thereby improving the overall structural strength of the heating element 12.
[0069] The fixing portion 121 and the electrical connecting element 13 are sintered and integrally formed, which is conducive to further improving the bonding force between the electrical connecting element 13 and the heating element 12.
[0070] It can be understood that in the embodiment in which the atomizing face 112 of the atomizing core 10 faces the mouthpiece end 50 (the atomizing core 10 atomizes upward), during the process in which the electrical connecting element 13 passes through the base body 11 to be electrically connected with the heating element 12 (such as mesh, thick film, thin film, etc.), due to the tolerances in the machining processes of the base body 11, the conductive element 20, the electrical connecting element 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, and there is a problem that the electrical connecting element 13 and the heating element 12 are difficult to be tightly assembled, and the heating element 12 may be pushed out of the atomizing face 112 by the electrical connecting element 13 or the bonding force is poor, thereby causing the assembly yield between the electrical connecting element 13 and the heating element 12 to be low, and the atomizing core 10 to fail.
[0071] The base 11 of the atomizing core 10 provided by the embodiment of the present application is provided with a through hole 113, two ends of the through hole 113 respectively penetrate the atomizing surface 112 and the liquid suction surface 111, and the electric connecting piece 13 is arranged in the through hole 113. In this way, the conductive piece 20 of the atomizer 100 can be arranged on one side of the liquid suction surface 111 to realize the electrical connection with the heating element 12. That is, the atomizing surface 112 can be arranged towards the mouth end 50 (the air outlet channel 30) to make the aerosol generated by the atomization of the aerosol generating substrate directly released to the mouth end 50 without turning, which is beneficial to reduce the loss of the aerosol, improve the taste explosion and the atomization efficiency. In addition, the heating element 12 is arranged to include at least one fixed part 121, and the fixed part 121 has a certain elasticity. In this way, a certain tolerance can exist when the electric connecting piece 13 is electrically connected with the fixed part 121, that is, the elastic deformation of the fixed part 121 can be released, which is beneficial to improve the situation that the electric connecting piece 13 pushes the heating element 12 away from the atomizing surface 112 due to the manufacturing tolerance or assembly, that is, to improve the stability of the electrical connection of the atomizing core 10, thereby improving the reliability of the atomizing core 10 and the assembly efficiency of the atomizing core 10.
[0072] In some embodiments, referring to Figures 4 to 6 The projection of the fixed part 121 on the atomizing surface 112 overlaps with the projection of the through hole 113.
[0073] That is, at least part of the structure of the fixed part 121 extends above the through hole 113, which is beneficial to the contact with the electric connecting piece 13.
[0074] Exemplarily, the projection of the fixed part 121 on the atomizing surface 112 overlaps with the projection of the electric connecting piece 13 to realize the electrical connection between the electric connecting piece 13 and the fixed part 121.
[0075] Exemplarily, the electric connecting piece 13 can be in a columnar shape, the columnar electric connecting piece 13 is arranged in the base 11, and two ends of the electric connecting piece 13 are respectively electrically connected with the fixed part 121 on one side of the atomizing surface 112 and the conductive piece 20 on one side of the liquid suction surface 111. That is, the electric connecting piece 13 penetrates the base 11 to realize the electrical connection between the heating element 12 and the conductive piece 20, and the heating element 12 realizes the electrical connection with the power supply assembly 200 through the conductive piece 20.
[0076] Exemplarily, the material of the electric connecting piece 13 can be gold, silver, copper or an alloy thereof, a stainless steel alloy, an iron-chromium-aluminum alloy, etc.
[0077] In this embodiment, by setting the projection of the fixing portion 121 and the projection of the through hole 113 to have an overlapping region, while realizing the electrical connection between the electrical connecting piece 13 and the fixing portion 121, i.e. at least part of the structure of the fixing portion 121 extends above the through hole 113 and is connected with the electrical connecting piece 13, it is beneficial to reduce the difficulty of forming the electrical connecting piece 13 and improve the stability of the electrical connection between the electrical connecting piece 13 and the fixing portion 121.
[0078] It should be noted that the cross-sectional shape of the through hole 113 is not limited here. Exemplarily, the cross-sectional shape of the through hole 113 can be circular, square, etc., and of course can also be other regular or irregular patterns.
[0079] Exemplarily, the cross-sectional shape of the through hole 113 is adapted to the shape of the electrical connecting piece 13.
[0080] Exemplarily, the cross-sectional shape of the through hole 113 is circular, which is adapted to the existing circular conductive piece 20, while improving the reliability of the electrical connection between the electrical connecting piece 13 and the conductive piece 20, it also improves the assembly efficiency.
[0081] In some embodiments, the maximum size of the projection of the through hole 113 on the atomizing face 112 is in the range of 0.5mm to 5mm.
[0082] The maximum size of the projection of the through hole 113 on the atomizing face 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.
[0083] Exemplarily, in the embodiment where the projection of the through hole 113 is circular, the maximum size of the projection of the through hole 113 on the atomizing face 112 is the aperture of the through hole 113, in the embodiment where the projection of the through hole 113 is rectangular, the maximum size of the projection of the through hole 113 on the atomizing face 112 is the diagonal of the projection of the through hole 113, and in the embodiment where the projection of the through hole 113 is other irregular patterns, the maximum size of the projection of the through hole 113 on the atomizing face 112 is the distance between the two most distant points of the projection.
[0084] Here, by setting the maximum size of the projection of the through hole 113 on the atomizing face 112 to be in the range of 0.5mm to 5mm, while improving the reliability of the electrical connection between the electrical connecting piece 13 and the fixing portion 121 and the conductive piece 20, it also to some extent improves the problem of reducing the structural strength of the base body 11 due to the through hole 113 being too large.
[0085] It should be noted that there are many structural forms of the fixing portion 121, as long as it can produce elastic deformation.
[0086] In some embodiments, referring to Figures 4 to 5 The heating element 12 includes an avoiding hole 124, one end of the fixing portion 121 is connected to the hole wall of the avoiding hole 124, and the other end extends towards the center of the avoiding hole 124.
[0087] That is, the fixing portion 121 forms an elastic cantilever by extending towards the center of the avoiding hole 124.
[0088] The specific forming manner of the heating element 12 is not limited here, and exemplarily, the heating element 12 can be formed by cutting a metal sheet.
[0089] Exemplarily, the avoiding hole 124 of the heating element 12 can be formed by hollowing out.
[0090] Here, by connecting one end of the fixing portion 121 to the hole wall of the avoiding hole 124 and extending the other end towards the center of the avoiding hole 124, a cantilever structure is formed, which facilitates the elastic deformation of the electrical connecting piece 13 when the electrical connecting piece 13 is electrically connected to the fixing portion 121, thereby improving the connection reliability between the electrical connecting piece 13 and the fixing portion 121.
[0091] Exemplarily, the width of the fixing portion 121 is in the range of 0.1mm to 1mm, which enables the fixing portion 121 to have a certain elasticity while also having a certain structural strength.
[0092] Exemplarily, the thickness of the fixing portion 121 is the same as the thickness of other regions of the heating element 12 except the fixing portion 121, which facilitates molding. Of course, the thickness of the fixing portion 121 can also be different from the thickness of other regions of the heating element 12 except the fixing portion 121, for example, the thickness of the fixing portion 121 is less than the thickness of other regions of the heating element 12 except the fixing portion 121.
[0093] Exemplarily, the length of the fixing portion 121 does not exceed the size of the avoiding hole 124.
[0094] Exemplarily, one end of the fixing portion 121 is connected to the hole wall of the avoiding hole 124, and the other end is a free end.
[0095] In some embodiments, at least part of the fixing portion 121 extends along a curve in the direction from the hole wall of the avoiding hole 124 to the center of the avoiding hole 124.
[0096] At least part of the fixing portion 121 extending along a curve means that the fixing portion 121 can be partially curved, and the other part can be straight, or the fixing portion 121 can be entirely curved.
[0097] That is, the fixed portion 121 can be a curved type, or a comprehensive type including both a curved type and a straight type.
[0098] It can be understood that the fixed portion 121 has different shapes, and the corresponding elastic deformation is also different. By setting at least part of the fixed portion 121 to extend along a curve under the same width, length and thickness, the elastic deformation of the fixed portion 121 is improved, thereby further improving the connection reliability between the electric connecting piece 13 and the fixed portion 121.
[0099] Here, the fixed portion 121 can be a horizontal cantilever structure, or an inclined cantilever structure.
[0100] It should be noted that the horizontal cantilever structure means that the heat generating piece 12 is in a flat plate structure, that is, the fixed portion 121 and other areas of the heat generating piece 12 except the fixed portion 121 are located in the same plane. The inclined cantilever structure means that at least part of the fixed portion 121 is arranged inclined to other areas of the heat generating piece 12 except the fixed portion 121.
[0101] In some embodiments, referring to Figure 4 , the fixed portion 121 includes a first connecting segment 122 and a second connecting segment 123. One end of the first connecting segment 122 is connected to the hole wall of the avoiding hole 124, and the other end extends towards the center of the avoiding hole 124 and is connected to the second connecting segment 123. The second connecting segment 123 extends away from one end of the first connecting segment 122 towards the direction of the through hole 113.
[0102] That is, the fixed portion 121 is a bent structure.
[0103] For example, the first connecting segment 122 extends in a horizontal direction, and the second connecting segment 123 extends in a vertical direction.
[0104] Here, by setting the fixed portion 121 to include the first connecting segment 122 and the second connecting segment 123, and by setting one end of the second connecting segment 123 away from the first connecting segment 122 to extend towards the direction of the through hole 113, the second connecting segment 123 is embedded in the electric connecting piece 13, thereby forming an effect similar to embedding a rivet, which is conducive to further enhancing the bonding force between the electric connecting piece 13 and the heat generating piece 12.
[0105] In some embodiments, referring to Figures 4 to 6 , the electric connecting piece 13 is configured to be formed by filling at least the through hole 113 with conductive paste.
[0106] That is, the electric connecting piece 13 can be formed by filling at least the through hole 113 with conductive paste in a grouting manner.
[0107] The phrase that the electrically conductive paste is filled at least in the through hole 113 means that the electrically conductive paste can be filled only in the through hole 113, or the electrically conductive paste can be filled in the through hole 113 and the avoiding hole 124 to jointly form the electric connection piece 13.
[0108] Exemplarily, the electrically conductive paste can be silver paste.
[0109] Here, by configuring the electric connection piece 13 to be formed by filling the electrically conductive paste at least in the through hole 113, the manufacturing process is simple, and it is beneficial to further enhance the bonding force between the electric connection piece 13 and the heat generating piece 12.
[0110] In some embodiments, referring to Figure 6 At least part of the structure of the fixing part 121 is embedded in the electrically conductive paste.
[0111] Exemplarily, the second connecting section 123 of the fixing part 121 is embedded in the electrically conductive paste.
[0112] Here, by configuring the fixing part 121 to include the first connecting section 122 and the second connecting section 123, and by configuring the second connecting section 123 to extend away from the one end of the first connecting section 122 towards the direction of the through hole 113, it is convenient for the second connecting section 123 to be embedded in the electrically conductive paste, thereby forming an effect similar to embedding a rivet, and it is beneficial to further enhance the bonding force between the electric connection piece 13 and the heat generating piece 12.
[0113] In some embodiments, referring to Figure 4 The projection of the through hole 113 is located in the projection range of the avoiding hole 124 on the atomization surface 112.
[0114] That is, the projection size of the through hole 113 is smaller than the projection size of the avoiding hole 124.
[0115] Here, by configuring the projection of the through hole 113 to be located in the projection range of the avoiding hole 124, in this way, when assembling the electric connection piece 13, it can be avoided that the electric connection piece 13 is pushed against the area of the heat generating piece 12 other than the fixing part 121, in this way, to a certain extent, it can be avoided that the electric connection piece 13 pushes the heat generating piece 12 out of the atomization surface 112, and it is beneficial to further improve the assembly yield between the electric connection piece 13 and the heat generating piece 12.
[0116] In some embodiments, referring to Figure 4 Each avoiding hole 124 corresponds to multiple fixing parts 121, and each fixing part 121 is arranged along the circumferential direction of the avoiding hole 124.
[0117] Exemplarily, the number of the avoiding holes 124 corresponds to the number of the electrode parts 125 one by one.
[0118] Here, the structure of the fixing portion 121 corresponding to each of the avoiding holes 124 can be the same or different.
[0119] Exemplarily, the fixing portions 121 are uniformly arranged along the circumferential direction of the avoiding holes 124.
[0120] In this embodiment, by arranging each of the avoiding holes 124 to correspond to multiple fixing portions 121, and arranging the fixing portions 121 along the circumferential direction of the avoiding holes 124 at intervals, the connection reliability of the electric connecting piece 13 and the heat generating piece 12 can be further improved.
[0121] In some embodiments, referring to Figure 6 , the size of the electric connecting piece 13 along the direction from the liquid suction surface 111 to the atomization surface 112 is greater than or equal to the size of the base body 11.
[0122] The direction from the liquid suction surface 111 to the atomization surface 112 refers to the thickness direction of the base body 11.
[0123] The size of the electric connecting piece 13 along the direction from the liquid suction surface 111 to the atomization surface 112 is greater than or equal to the size of the base body 11, that is, the size of the electric connecting piece 13 along the direction from the liquid suction surface 111 to the atomization surface 112 is greater than or equal to the thickness of the base body 11.
[0124] Here, by arranging the size of the electric connecting piece 13 to be greater than or equal to the size of the base body 11 along the direction from the liquid suction surface 111 to the atomization surface 112, the electric connecting piece 13 can be in contact with the fixing portion 121 and the conductive piece 20.
[0125] In some embodiments, the electric connecting piece 13 is provided with a connecting portion at one end close to the liquid suction surface 111, and the maximum size of the projection of the connecting portion on the liquid suction surface 111 is greater than the maximum size of the projection of the through hole 113.
[0126] Here, by arranging the maximum size of the projection of the connecting portion to be greater than the maximum size of the projection of the through hole 113 on the liquid suction surface 111, the connecting portion can be prevented from extending into the through hole 113, thereby improving the assembly efficiency and the electrical connection reliability of the electric connecting piece 13 and the conductive piece 20.
[0127] In some embodiments, referring to Figures 4 to 6 , the electric connecting piece 13 protrudes from the atomization surface 112, or the electric connecting piece 13 is flush with the atomization surface 112.
[0128] In embodiments in which the fixing portion 121 is not arranged to be inclined towards the through hole 113, if the electric connecting piece 13 does not protrude from the atomization surface 112, the connection of the electric connecting piece 13 and the fixing portion 121 is not facilitated.
[0129] 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.
[0130] 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 connect the electrical connector 13 to the fixing part 121. Furthermore, the fixing 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.
[0131] 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.
[0132] 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.
[0133] 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.
[0134] 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 conducive to the connection between the electrical connector 13 and the fixing 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.
[0135] 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.
[0136] 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.
[0137] For example, the electrode portion 125 may be provided with a plurality of openings, the openings surrounding the periphery of the fixing portion 121, that is, the openings surrounding the periphery of the clearance hole 124.
[0138] 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.
[0139] 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.
[0140] 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.
[0141] 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.
[0142] Since the heating wire 1261 is provided with retaining rings 1262 on both sides, it is beneficial to improve the bonding force between the heating part 126 and the substrate, thereby improving the bonding force between the heating element 12 and the substrate 11. Furthermore, by setting the opening in the retaining rings 1262, it is beneficial to further improve the bonding force between the heating element 12 and the substrate 11.
[0143] In other embodiments, the heating element 12 is integrally formed with the substrate 11. This helps reduce the number of parts, improves assembly efficiency, and enhances the bonding force between the heating element 12 and the substrate 11.
