[0047] Currently, ceramic heating elements are widely used in the atomization cores of electronic atomization devices. The ceramic heating element includes a ceramic liquid-inlet base and a metal heating element fixed to the surface of the ceramic liquid-inlet base. The aerosol matrix is transported to the metal heating body by the capillary action of the liquid-absorbing holes on the ceramic liquid-inlet base, and the metal heating element heats the aerosol matrix to atomize it. The metal heating element is formed with an electrode sheet connected to the battery in the electronic atomizer through an electrode conductor. However, in the prior art, the flat surface of the electrode sheet and the end of the electrode conductor are connected in a contact-type conductive manner, resulting in a small conductive contact area and prone to structural contact instability.
[0048] To address these issues, the present application proposes a heating element. This design forms a recess on the electrical contact surface of an electrode connector, allowing the end of the electrode conductor to be embedded within the recess. The recess acts as a contact limiter for the electrode conductor, improving the structural stability between the electrode conductor and the connector. Furthermore, embedding the electrode conductor within the recess increases the conductive contact area and enhances conductive stability.
[0049] refer to Figure 5 、 Figure 6 , an embodiment of the present application provides an electronic atomization device 100 , including an atomizer 300 and a battery assembly 2 for powering the atomizer 300 .
[0050] refer to Figure 3 、 Figure 5 In some embodiments, the atomizer 300 includes an atomizing shell 1 having a liquid storage tank 101 and an atomizing core 3 disposed in the atomizing shell 101; the atomizing core 3 is used to heat and atomize the aerosol matrix in the liquid storage tank 101; the atomizing core 3 includes a liquid inlet substrate 4 and a heating element 5, and the liquid inlet substrate 4 has a liquid inlet surface 401 and an atomizing surface 402 that are opposite to each other.
[0051] Specifically, the battery assembly 2 includes a battery 201 and an electrode conductor 202 electrically connected to the battery 201. The end of the electrode conductor 202, remote from the battery 201, contacts the atomizer core 3 for electrical conductivity. The electrode conductor 202 may be, but is not limited to, an electrical connector such as a spring pin or a plug. The battery 201 supplies power to the atomizer core 3 via the electrode conductor 202. The atomizer core 3 is electrically connected to the liquid inlet of the liquid reservoir 101. When energized, the atomizer core 3 heats and atomizes the aerosol matrix to generate atomized gas for the user to inhale.
[0052] It is understood that the electronic atomization device 100 of the present application can be a replaceable electronic atomization device 100, that is, the atomizer 300 and the battery assembly 2 are detachably connected. Alternatively, the electronic atomization device of the present application can also be a disposable electronic atomization device 100, that is, the atomizer 300 and the battery assembly 2 are not detachably connected. This is not specifically limited here, as long as the battery 201 can power the atomization core 3.
[0053] In some embodiments, the liquid inlet substrate 4 is a porous ceramic body, and the liquid inlet surface 401 of the liquid inlet substrate 4 is connected to the liquid storage tank 101 in the atomizing shell 1. The porous structure of the liquid inlet substrate 4 forms a capillary action to transport the aerosol matrix to the atomizing surface 402 of the liquid inlet body 2. Figure 3 、 Figure 6 The heating element 5 is electrically connected to the electrode conductor 202 . When the heating element 5 is powered on, it generates heat to effectively heat and atomize the aerosol matrix on the atomization surface 402 .
[0054] It can be understood that the heating element 5 and the electrode conductor 202 are in contact conduction; Figure 6 In the electronic atomization device 100 of the present application, the upper end of the electrode conductor 202 abuts against the heating element 5 to achieve electrical connection between the two.
[0055] refer to Figure 1 、 Figure 2In some embodiments, the heating element 5 includes a heating body 501 and an electrode connector 502 provided on the heating body 501; the electrode connector 502 forms an electrical contact surface 6; the electrode connector 502 forms a recess 7 on the electrical contact surface 6, and the end of the electrode conductor 202 can be embedded in the recess 7.
[0056] Specifically, the heating element 1 is a metal body, and the number of the electrode connectors 502 is at least two. The two spaced-apart electrode connectors 502 serve as two electrodes of the heating element 5 and are electrically connected to the electrode conductor 202 respectively, thereby energizing and heating the heating body 501 therebetween.
[0057] The electrode connector 502 is a sheet or plate-like structure, and the recess 7 is a depression or groove formed on the electrical contact surface 6. When the electrode conductor 202 is electrically connected to the electrode connector 502, the end of the electrode conductor 202 can be embedded in the recess 7. The recess 7 can serve as a contact limiter for the electrode conductor 202, thereby improving the structural stability between the electrode conductor 202 and the electrode connector 502. Furthermore, the embedding of the electrode conductor 202 in the recess 7 changes the conductive contact method from the original planar contact method to an embedded method, which can effectively increase the conductive contact area and improve conductive stability.
[0058] Here, there is no limitation on the specific forming method of the recess 7 structure, as long as the end of the electrode conductor 202 can be embedded in the recess 7.
[0059] For example, the electrode connector 502 can be a thin sheet-like structure, with recesses 7 formed on the electrical contact surface 6 by processing and deforming a portion of the electrode connector 502 in its thickness direction, while a corresponding protrusion forms on the side facing away from the electrical contact surface 6. Alternatively, the electrode connector 502 can be a plate-like structure with a certain thickness, with recesses 7 formed by directly cutting grooves in the electrical contact surface 6.
[0060] There are two or more electrode connectors 502 . All of the electrode connectors 502 can be processed so that each electrode connector 502 has a recess 7 . Alternatively, only one or several of the electrode connectors 502 can be selectively processed so that a portion of the electrode connectors 502 has a recess 7 .
[0061] refer to Figure 1 、 Figure 2 In some embodiments, the electrode connector 502 is a sheet-like structure. The electrode connector 502 has a connecting surface 8 facing away from the electrical contact surface 6 . A convex portion 9 corresponding to the concave portion 7 is formed on the connecting surface 8 .
[0062] As can be understood, the connection surface 8 is in close contact with the atomizing surface 402 of the liquid-inlet substrate 4. The electrode connector 502 is a thin metal sheet, utilizing its ductility. Therefore, by deforming a portion of the electrode connector 502 in the thickness direction, a recess 7 is formed on the electrical contact surface 6. The portion of the connection surface 8 corresponding to the recess 7 is then protruded to form a protrusion 9. By forming the protrusion 9 on the connection surface 8 and the recess 7 on the electrical contact surface 6 simultaneously, the thickness of the electrode connector 502 does not need to be changed, resulting in an ingenious structural design and wide adaptability.
[0063] refer to Figure 3 、 Figure 4 In some embodiments, the liquid inlet substrate 4 is formed with an embedding groove 10 on the atomizing surface 402 , and the protrusion 9 on the electrode connecting surface 8 is embedded in the embedding groove 10 .
[0064] Specifically, the liquid inlet base 4 is a ceramic body, which is formed in a mold. During the molding process, the liquid inlet base 4 is combined with the heating element 5 in the mold. After molding, the connection surface 8 of the electrode connector 502 is tightly connected to the atomizing surface 402 of the liquid inlet body 2, and the electrical contact surface 6 and recess 7 are exposed to the outside. The connection between the heating element 1 and the liquid inlet body 2 is tight and stable, and the structure is stable.
[0065] Understandably, reference Figure 4 Since a protrusion 9 is formed on the connecting surface 8 of the electrode connector 502, a corresponding embedding groove 10 will be formed on the atomizing surface 402 of the liquid inlet substrate 4 during the molding process of the liquid inlet substrate 4 and the heating element 5, and the protrusion 9 is tightly embedded in the embedding groove 10.
[0066] Then, the protrusion 9 cooperates with the embedding groove 10 to increase the connection area between the electrode connector 502 and the liquid inlet matrix 4, so that the connection between the electrode connector 502 and the liquid inlet matrix 4 is more firmly established, thereby improving the structural stability.
[0067] refer to Figure 2 、 Figure 3 In some embodiments, the recess 7 has a concave surface 701 , and the end of the electrode conductor 202 has a contact surface 11 ; the concave surface 701 is configured to fit with the contact surface 11 .
[0068] Specifically, the abutting surface 11 of the electrode conductor 202 can be, but is not limited to, a spherical arc surface, a rectangular plane, a conical surface, etc.; the shape structure of the recess 7 is set to be compatible with the abutting surface 11 of the electrode conductor 202, so that when the electrode conductor 202 is embedded in the recess 7, the abutting surface 11 of the electrode conductor 202 will fit tightly with the concave surface 701, so that the electrode conductor 202 is in close contact with the electrode connector 502, and can effectively increase the conductive contact area and improve the conductive stability.
[0069] refer to Figure 2 、 Figure 7 In some embodiments, the abutting surface 11 is a spherical arc surface, and the concave surface 701 is set to a spherical concave surface.
[0070] It can be understood that the abutting surface 11 is a spherical arc surface, and the concave surface 701 is correspondingly set to a spherical concave surface, so that the contact between the abutting surface 11 of the electrode conductor 202 and the concave surface 701 is more closely fitted. The spherical contact has a large contact surface and the force is evenly dispersed, thereby improving the conductive stability.
[0071] In some embodiments, electrode connectors 502 are respectively provided at two opposite ends of the heating body 501 , and recesses 7 are formed on the electrical contact surfaces 6 of the two electrode connectors 502 .
[0072] Specifically, the present embodiment includes two electrode connectors 502, each located at either end of the heating body 501 and forming a positive and negative electrode for electrical connection to the external electrode conductor 202. Furthermore, a recess 7 is formed on each of the two electrode connectors 502, ensuring good electrical conductivity and stability between the electrode connectors 502 and the electrode conductor 202.
[0073] refer to Figure 1 、 Figure 2 In some embodiments, the heating body 501 includes a plurality of heating wires 5011 connected to each other in an interlaced manner and meshes 5012 formed between the heating wires 5011 , and the meshes 5012 are circular, elliptical, prismatic, triangular or polygonal in shape.
[0074] It can be understood that the heating body 501 can be a mesh metal heating element, also known as a mesh heating net. In some embodiments, the heating body 501 can be designed with a honeycomb, prismatic or rectangular pattern structure as required to better atomize the aerosol to generate the matrix, and the resistance value and heat concentration of the heating body can be adjusted by controlling the pattern size.
[0075] In some embodiments, the electrode connector 502 and the heating body 501 are integrally formed.
[0076] The electrode connector 502 and the heating body 501 are both made of metal, and the heating element 5 can be made from a whole piece of metal sheet through chemical etching, stamping, laser / mechanical engraving, etc. to form the electrode connector 502 and the heating body 501, with good structural integrity and stable structure.
[0077] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
