Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization, in particular to a spliced atomization core, a preparation method thereof, a welding positioning mold and an atomization device. BACKGROUND

[0002] Mesh core (grid-shaped atomization core) is widely used in various electronic cigarette supply chain markets due to its advantages of fast heating speed, large contact area, uniform atomization, etc. Etched mesh core, as a processing type of mesh core, is obtained by etching stainless steel, nickel-chromium-iron, iron-chromium-aluminum, etc. into a grid shape through etching process, which is widely used in existing disposable electronic cigarette products. In addition, some grid-shaped atomization cores are obtained based on stamping forming process or CNC process.

[0003] Although the mesh core has various performance advantages for tobacco tar atomization, the special structure of the mesh core makes it very difficult to combine with the oil guiding cotton for production and assembly, the assembly positioning is poor, it is difficult to realize automatic production, the assembly position is uneven, and the same product may have different smoking tastes due to assembly problems.

[0004] To solve the assembly problem of the mesh core, a round steel rod is usually used to assist in the mesh core assembly process, the mesh core is attached to the steel rod to press the mesh core into a circular shape, and a layer of oil guiding cotton is wrapped outside the mesh core to form an atomization module. Although the application of the above process solves the forming and assembly problem of the mesh core to some extent, the steel rod must exist throughout the assembly process of the atomization module in order to maintain the circular shape of the mesh core, which causes great material waste, and the assembly method is affected by the precision of manual or machine in the production process.

[0044] In order to have a clearer understanding of the technical features, objectives and effects of the application, the specific embodiments of the application will be described in detail with reference to the drawings.​​​​

[0045] Reference Figure 1 and Figure 2 The spliced atomizing core 1 of some embodiments of the present application comprises at least two single mesh assemblies 10, and the at least two single mesh assemblies 10 are sequentially connected to form a cylindrical body.

[0046] Each single mesh assembly 10 is flat when unfolded. When two or more single mesh assemblies 10 are connected end to end, each single mesh assembly 10 is bent to form an arc shape, so that the plurality of arc-shaped single mesh assemblies 10 are connected end to end to form a cylindrical spliced atomizing core 1. The cylindrical atomizing core structure is stable, and the liquid guide can be directly filled in the inside (inner ring space) of the atomizing core or wrapped around the outer periphery of the atomizing core when assembled to form an atomizing module, without the need to insert a steel rod for assistance during assembly.

[0047] Each single mesh assembly 10 can include a heating mesh 11 and a conductive pin 12. In the atomizing core formed by splicing the single mesh assemblies 10, the conductive pin 12 extends outward along the axial direction of the cylindrical atomizing core, and is used to connect with a power supply device to make the heating mesh 11 generate heat and produce a large amount of Joule heat, which can atomize the atomizing liquid into aerosol.

[0048] Of course, the conductive pin 12 can also be included in at least two single mesh assemblies 10, that is, at least one single mesh assembly 10 includes a heating mesh 11 but does not include a conductive pin 12, and the remaining single mesh assemblies 10 include a heating mesh 11 and a conductive pin 12. For the atomizing core formed by splicing two single mesh assemblies 10, at least two conductive pins 12 corresponding to the positive and negative electrodes respectively, the two conductive pins 12 can be connected to the two heating meshes 11 respectively, or connected to one heating mesh 11. For the atomizing core formed by splicing three or more single mesh assemblies 10, at least two conductive pins 12 corresponding to the positive and negative electrodes respectively, the two conductive pins 12 can be connected to the two heating meshes 11 respectively or connected to one heating mesh 11, wherein the heating mesh 11 of one single mesh assembly 10 does not have a conductive pin 12, but is electrically connected to the conductive pin 12 through the adjacent connected heating mesh 11.

[0049] The heating mesh 11 is made of a material with a certain resistivity, including but not limited to stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, etc.; the material of the conductive pin 12 can be pure Ni, pure copper or other high-conductivity metal or alloy materials.

[0050] Specifically, referring to Figure 2 and Figure 3The heating net 11 has opposite first and second ends, the first end is provided with a first sawtooth part 111, and the second end is provided with a second sawtooth part 112, the second sawtooth part 112 is matched with the first sawtooth part 111, that is, the two can be matched in concave-convex. Each single net assembly 10 is configured such that the tooth shape of the first sawtooth part 111 at the first end can be docked with the second sawtooth part 112 at the second end.

[0051] When two heating nets 11 are spliced, the first sawtooth part 111 on the first end of one heating net 11 is embedded and docked with the second sawtooth part 112 on the second end of the other heating net 11, which not only helps the accurate docking between the heating nets 11, but also strengthens the stability of the docking between the heating nets 11, avoiding relative movement misplacement.

[0052] The first sawtooth part 111 includes a plurality of sawteeth, and the second sawtooth part 112 also includes a plurality of sawteeth, the shapes of the sawteeth of the first sawtooth part 111 and the second sawtooth part 112 can be triangular, arc-shaped or square-shaped, etc., so that the first sawtooth part 111 and the second sawtooth part 112 can be but are not limited to triangular sawteeth, wave-shaped sawteeth or square-shaped sawteeth. Of course, the first sawtooth part 111 can also be a combination of triangular sawteeth, wave-shaped sawteeth and square-shaped sawteeth, and the second sawtooth part 112 is correspondingly arranged with the first sawtooth part 111.

[0053] In Figure 2 and Figure 3 The conductive pin 12 is fixed at the first end of the heating net 11, the length direction of the conductive pin 12 is parallel to the length direction of the first end of the heating net 11. Further, the first end of the heating net 11 is stacked on a surface of the conductive pin 12 and can be fixed by welding, so that the first sawtooth part 111 on the first end is also located on a surface of the conductive pin 12, so that the surface of the conductive pin 12 also serves as a docking bearing surface, and the second sawtooth part 112 of the other heating net 11 can be abutted on the docking bearing surface of the conductive pin 12 while being docked with the first sawtooth part 111.

[0054] In each adjacent connected two single net assemblies 10, the second end of one heating net 11 is embedded and docked with the first sawtooth part 111 of the other heating net 11 in the circumferential direction of the cylindrical body. When the conductive pin 12 is connected to the first end of the heating net 11, the structure after the second sawtooth part 112 and the first sawtooth part 111 are docked is also fixed on the conductive pin 12.

[0055] Further, as Figure 3As shown, the heating net 11 also has another two opposite ends, which are a third end and a fourth end. The third end and the fourth end are respectively provided with a plurality of outwardly extending heat conduction portions 113, and the heat conduction portions 113 are provided with fixing teeth 114, which can be inserted into the liquid guide member to relatively fix the liquid guide member and the heating net 11, avoid random sliding during use or assembly to the atomization device, and ensure the consistency of the atomization effect of the atomization device.

[0056] The fixing teeth 114 on the heating net 11 have an inclination angle, and the fixing teeth 114 with the inclination angle are inserted into the liquid guide member, so that the atomization core is fixed in position in the cotton and is in closer contact with the liquid guide member.

[0057] The heat conduction portion 113 can be a strip structure, and the fixing teeth 114 are arranged on at least one side edge of the heat conduction portion 113, such as Figure 3 opposite sides of the heat conduction portion 113. The fixing teeth can also be arranged on the outer side of the heat conduction portion 113 away from the heating net 11 as needed.

[0058] The fixing teeth 114 on each side edge of the heat conduction portion 113 can be, but are not limited to, triangular sawteeth, wavy sawteeth or square sawteeth, or a combination of triangular sawteeth, wavy sawteeth and square sawteeth.

[0059] In the single-net assembly 10 of the present application, the heating net 11 can include a heating area 110, two connecting areas 120 formed at opposite ends of the heating area 110, and two heat conduction areas 130 formed at another two opposite ends of the heating area 110 according to functions. The first end and the second end of the heating net 11 form the connecting areas 120, respectively, and the third end and the fourth end of the heating net 11 form the heat conduction areas 130, respectively.

[0060] The heating area 110 is the main part of the heating net 11 and is in a grid shape, which can be Figure 3 a rhombic grid as shown, or other polygons such as a quadrilateral grid, a circular grid or an elliptical grid, or a combination of the above grid structures. The heating area 110 is a joule heat generation area, and generates a large amount of heat after being electrified. The heat can be spread to the surrounding area through the heat conduction areas 130 under the action of heat conduction, so as to expand the overall atomization area of the heating net 11. The connecting areas 120 of the heating net 11 are used to connect the conductive pins 12 and the connection between the heating net 11.

[0061] In Figure 2 and Figure 3In the illustrated embodiment, the first and second ends of the heating mesh 11 are respectively formed by edge heating strips of the heating area 110, and the first serrated portion 111 and the second serrated portion 112 are respectively formed on the side edges of the edge heating strips on the corresponding sides. After the two heating meshes 11 are joined together by the first serrated portion 111 and the second serrated portion 112, the edge heating strip where the first serrated portion 111 is located and the edge heating strip where the second serrated portion 112 is located can be joined to form a complete rectangular strip structure.

[0062] like Figure 1 and Figure 2 As shown, preferably, the spliced ​​atomizing core 1 includes two single-mesh components 10, which are connected end-to-end to form a... Figure 1 The cylindrical atomizing core shown.

[0063] During connection, the previous single network component 10 (such as...) Figure 2 The second end of the heating mesh 11 of the single mesh component 10 on the right side of the middle is connected to the next single mesh component 10 (such as...). Figure 2 The first ends of the heating mesh 11 of the single mesh assembly 10 on the left side are fitted together, that is, the second serrated portion 112 of the second end is fitted with the first serrated portion 111 of the first end through a concave-convex fit. The fitting is performed on the conductive pin 12 of the latter single mesh assembly 10. Then, the two single mesh assemblies 10 are bent so that the second end of the heating mesh 11 of the latter single mesh assembly 10 is fitted together with the first end of the heating mesh 11 of the former single mesh assembly 10, that is, the second serrated portion 112 of the second end of the latter heating mesh 11 is fitted with the first serrated portion 111 of the first end of the former heating mesh 11 through a concave-convex fit. The fitting is performed on the conductive pin 12 of the former single mesh assembly 10. In this way, the two single mesh assemblies 10 are joined together to form a cylindrical atomizing core.

[0064] like Figure 4 As shown, in other embodiments, the first end of the heating mesh 11 of each single mesh assembly 10 is C-shaped in the transverse direction, and the first serrated portion 111 is provided on the two outward ends of the C-shape; the second end of the heating mesh 11 is C-shaped in the transverse direction, and the second serrated portion 112 is provided on the two outward ends of the C-shape.

[0065] A conductive pin 12 is provided between two adjacent single-network components 10. The first end and the second end of the C-shape are connected to each other through the first serrated part 111 and the second serrated part 112 to form a closed cylindrical shape that can surround the conductive pin 12.

[0066] Specifically, as preferred, each single mesh assembly 10 can include one conductive pin 12, and the conductive pin 12 of each single mesh assembly 10 can be fixed inside the C-shaped first end of the heating mesh 11. When two single mesh assemblies 10 are connected to form a cylindrical atomizing core, the second end of the heating mesh 11 of the former single mesh assembly 10 and the first end of the heating mesh 11 of the latter single mesh assembly 10 are embedded and connected to each other, i.e., the first sawtooth part 111 of the first end and the second sawtooth part 112 of the second end are embedded and connected to each other, so that the first end and the second end form a circular structure, and the conductive pin 12 of the latter single mesh assembly 10 is also wrapped inside. The second end of the heating mesh 11 of the latter single mesh assembly 10 and the first end of the heating mesh 11 of the former single mesh assembly 10 are embedded and connected to each other, i.e., the second sawtooth part 112 of the second end of the latter heating mesh 11 and the first sawtooth part 111 of the first end of the former heating mesh 11 are embedded and connected to each other, so that the second end and the first end form a circular structure, and the conductive pin 12 of the former single mesh assembly 10 is also wrapped inside.

[0067] In combination Figures 1 to 7 , the method for manufacturing the spliced atomizing core of the present application can include the following steps:

[0068] S1, providing at least two single mesh assemblies 10, and connecting the at least two single mesh assemblies 10 in sequence to form a spliced module, as shown in the structure of Figure 2 .

[0069] Among the opposite two ends of the spliced module, one end is the first end of one heating mesh 11 with a conductive pin 12 and a first sawtooth part 111 (such as the right side in Figure 2 ), and the other end is the second end of another heating mesh 11 with a second sawtooth part 112 (such as the left side in Figure 2 ).

[0070] S2, providing a welding positioning mold 20.

[0071] As shown in Figure 5 and Figure 6 , the mold cavity of the welding positioning mold 20 is a cylindrical cavity 21 (the radial cross section is circular), and the side surface of the welding positioning mold 20 is provided with a welding opening 22 that communicates and extends axially along the cylindrical cavity 21, and the inner surface of the cylindrical cavity 21 is provided with at least one positioning groove 23 parallel to the welding opening 22.

[0072] The positioning groove 23 is arranged according to the conductive pin 12, so as to accommodate and position the conductive pin 12 therein. For example, when the conductive pin 12 is a square pin, the positioning groove 23 is a square groove; when the conductive pin 12 is a round pin, the positioning groove 23 is a round groove.

[0073] S3. Place the splicing module into the cylindrical cavity 21 of the welding positioning mold 20, and position one conductive pin 12 on the splicing module into the positioning groove 23. The two sides of the splicing module are spliced ​​together at the welding opening 22 under the pressure of the mold.

[0074] by Figure 2 Taking a splicing module with two single mesh components 10 as an example, when it is placed into the cylindrical cavity 21 of the welding positioning mold 20, the conductive pin 12 located in the middle is accommodated and positioned in the positioning groove 23 of the cylindrical cavity 21. The other parts of the two single mesh components 10 are attached to the inner surface of the cylindrical cavity 21, while the opposite ends of the single mesh components 10 (i.e., the first serrated part 111 and the second serrated part 112) are spliced ​​at the welding opening 22.

[0075] The splicing module can be placed into the welding positioning mold 20 as follows:

[0076] In one embodiment, at least one end of the cylindrical cavity 21 is open. The splicing module is bent to correspond to the inner circumference of the cylindrical cavity 21 and inserted into it from the open end, moving inward along the axial direction of the cylindrical cavity 21 until it is in place. In the in-place state, the conductive pin 12 located in the middle of the splicing module is received and positioned in the positioning groove 23 of the cylindrical cavity 21. The other parts of the splicing module are attached to the inner surface of the cylindrical cavity 21, while the first serrated portion 111 and the second serrated portion 112 at opposite ends of the splicing module are joined at the welding opening 22 under the extrusion of the mold.

[0077] In another embodiment, the welding positioning mold 20 can be formed by docking two unit molds in the axial direction; the two unit molds can be disassembled after docking, which facilitates the removal of the assembled atomizing core. In step S3, one end of the splicing module is inserted into the cylindrical cavity 21 through the welding opening 22 of the welding positioning mold 20, and moves along the inner circumferential surface of the cylindrical cavity 21 until the first serrated portion 111 and the second serrated portion 112 at both ends of the splicing module are joined at the welding opening 22 under the pressure of the mold. At the same time, the conductive pin 12 located in the middle of the splicing module is accommodated and positioned in the positioning groove 23 of the cylindrical cavity 21.

[0078] S4. Weld the two ends of the splicing module at the welding opening 22, so that the second serrated part 112 and the first serrated part 111 at the splicing point are connected as one unit and fixed on the conductive pin 12. Welding can be performed by laser welding or spot welding.

[0079] refer to Figure 4 When the first and second ends of the heating mesh 11 of each single mesh component 10 are both C-shaped, the step of sequentially connecting each single mesh component 10 to form a splicing module in the above preparation method may specifically include:

[0080] The first end of one of the single mesh assemblies 10 provided with the conductive pin 12 is butted and welded with the second end of the adjacent single mesh assembly 10 not provided with the conductive pin 12 through the first serration 111 and the second serration 112, so that the conductive pin 12 is surrounded between the serrations of the two adjacent single mesh assemblies 10 (i.e. between the first serration 111 and the second serration 112), thereby the single mesh assemblies 10 are connected to form the spliced module.

[0081] The step of splicing the opposite ends of the spliced module at the welding opening further comprises:

[0082] The first end of one of the single mesh assemblies 10 provided with the conductive pin 12 is butted and welded with the second end of the adjacent single mesh assembly 10 not provided with the conductive pin 12 through the serrations (i.e. the first serration 111 and the second serration 112) at the welding opening 22 of the welding positioning mold 20, and then connected by welding, thereby forming a cylindrical atomizing core.

[0083] The cylindrical atomizing core (i.e. the spliced atomizing core 1) prepared by the above preparation method can be moved along the axial direction of the cylindrical cavity 21 and slid out of the open end of the welding positioning mold 20 when it is separated from the welding positioning mold 20. Alternatively, when the welding positioning mold 20 is formed by butting two unit molds in the axial direction, the two unit molds can be disassembled, and at this time the cylindrical atomizing core can be taken out.

[0084] The spliced atomizing core 1 of the present application is assembled with the liquid guide to form an atomizing module, which is suitable for use in an atomizing device or an electronic cigarette.

[0085] As shown in Figure 8 , in the atomizing module, the liquid guide 30 is filled in the inside of the spliced atomizing core 1 or wrapped around the outer periphery of the spliced atomizing core 1. When the spliced atomizing core 1 has the fixing teeth 114, the fixing teeth 114 are inserted into the liquid guide 30, so that the spliced atomizing core 1 is relatively fixed with the liquid guide 30.

[0086] In combination Figure 3 and Figure 8 , in the spliced atomizing core 1, the fixing teeth 114 on the heating mesh 11 form an included angle with the heating mesh 11, i.e. the fixing teeth 114 have a certain inclination angle on the heating mesh 11. After the liquid guide 30 is filled in the spliced atomizing core 1, the fixing teeth 114 with the inclination angle are inserted into the liquid guide 30, so that the atomizing core is fixed in position in the cotton and is in closer contact with the liquid guide 30, thereby ensuring that the external tobacco tar enters the surface of the atomizing core more smoothly through the liquid guide 30 during use.

[0087] The liquid guide 30 can be a liquid guiding cotton made of cotton material, or a liquid guide made of porous material such as fiber.

[0088] Further, with reference toFigure 8 and Figure 9 The atomization module of the present application can further include a liquid storage cotton 40, which is wrapped around the outer periphery of the spliced atomization core 1, and the liquid guide 30 and the liquid storage cotton 40 form an inner and outer wrapping to the spliced atomization core 1. The fixing teeth 114 on the heating net 11 can also be inserted into the liquid storage cotton 40, so that the spliced atomization core 1 is relatively fixed with the liquid storage cotton 40, thereby forming a relatively fixed module of the liquid guide 30, the spliced atomization core 1 and the liquid storage cotton 40, avoiding random sliding during use or assembly to the atomization device, and ensuring the consistency of the atomization effect of the atomization device.

[0089] Further, referring to Figure 1 and Figure 1 The atomization device of the present application includes the above spliced atomization core 1.
