Description

Spliced ​​atomizer core and preparation method thereof, welding positioning mold and atomizer device Technical Field

[0001] The present invention relates to the field of atomization technology, and in particular to a spliced ​​atomization core and a preparation method thereof, a welding positioning mold and an atomization device. Background Art

[0002] Mesh cores (grid-like atomizer cores) are widely used across various e-cigarette supply chains due to their advantages, including fast heating, large contact area, and uniform atomization. Etched mesh cores, a type of mesh core processing method, are created by etching thin sheets of stainless steel, nickel-chromium-iron, or iron-chromium-aluminum into a grid-like shape. They are widely used in existing disposable e-cigarette products. Additionally, some mesh-like atomizer cores are produced using stamping or CNC processes.

[0003] Although using mesh core for e-liquid atomization has many performance advantages, the special structure of the mesh core makes it very difficult to produce and assemble it in combination with the oil-guide cotton. The assembly position is poor, making it difficult to achieve automated production. The assembly position is uneven, and assembly problems can easily lead to inconsistent puffing taste in the same product.

[0004] To address the mesh core assembly problem, a round steel rod is typically used during the assembly process. By fitting the mesh core and the rod together, the mesh core is pressed into a round shape. A layer of oil-conducting cotton is then wrapped around the mesh core to form the atomizer module. While this process solves the mesh core assembly problem to some extent, the steel rod must be present throughout the entire atomizer module assembly process to maintain the mesh core's circular shape, resulting in significant material waste. Furthermore, this assembly method is subject to the precision of both manual and machine control during production. Summary of the Invention

[0044] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0045] 1 and 2 , a spliced ​​atomizer core 1 according to some embodiments of the present invention includes at least two single mesh components 10 , and the at least two single mesh components 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 joined end to end, each single mesh assembly 10 is bent and deformed into an arc. Consequently, multiple arc-shaped single mesh assemblies 10, when joined end to end, form a cylindrical spliced ​​atomizer core 1. The cylindrical atomizer core is structurally stable and can be assembled with a liquid guide, either by directly filling the interior of the atomizer core (inner ring space) or wrapping the liquid guide around the outer circumference of the atomizer core to form an atomizer module. This eliminates the need for inserting a steel rod into the atomizer core during assembly.

[0047] Each single mesh assembly 10 includes a heating mesh 11 and a conductive pin 12. In the atomizer core formed by splicing the single mesh assemblies 10, the conductive pin 12 extends outward along the axial direction of the cylindrical atomizer core and is used to connect to a power supply. When the heating mesh 11 is energized, it heats up, generating a large amount of Joule heat, which can atomize the atomized liquid into an aerosol.

[0048] Of course, the conductive pins 12 may also be included in at least two single-net components 10, that is, at least one single-net component 10 includes a heating net 11 but does not include a conductive pin 12, and the remaining single-net components 10 include a heating net 11 and a conductive pin 12. For an atomizer core formed by splicing two single-net components 10, there are at least two conductive pins 12 corresponding to the positive and negative poles, respectively. The two conductive pins 12 can be connected to the two heating nets 11, or to one heating net 11. For an atomizer core formed by splicing three or more single-net components 10, there are at least two conductive pins 12 corresponding to the positive and negative poles, respectively. The two conductive pins 12 can be connected to the two heating nets 11, or to one heating net 11. Among them, the heating net 11 of a single-net component 10 does not have a conductive pin 12, but is conductively connected to the conductive pin 12 through its adjacent heating net 11.

[0049] The heating network 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 conductive pin 12 can be made of pure Ni, pure copper or other metals or alloys with high electrical conductivity.

[0050] Specifically, referring to Figures 2 and 3, the heating net 11 has a first end and a second end opposite each other. The first end is provided with a first serrated portion 111, and the second end is provided with a second serrated portion 112. The second serrated portion 112 is adapted to the first serrated portion 111, that is, the two can be matched in a concave and convex manner. Each single net assembly 10 is configured so that the tooth shape of the first serrated portion 111 at the first end can mate with the second serrated portion 112 at the second end.

[0051] When two heating nets 11 are spliced ​​together, the first serrated portion 111 on the first end of one heating net 11 is engaged with the second serrated portion 112 on the second end of the other heating net 11. This not only helps to accurately connect the heating nets 11, but also enhances the stability of the connection between the heating nets 11 and avoids relative movement and dislocation.

[0052] The first serration portion 111 includes a plurality of serrations, and the second serration portion 112 also includes a plurality of serrations. The serrations of the first serration portion 111 and the second serration portion 112 can be triangular, arc-shaped, or square-shaped, respectively. Thus, the first serration portion 111 and the second serration portion 112 can be, but are not limited to, triangular serrations, wavy serrations, or square serrations. Of course, the first serration portion 111 can also be a combination of triangular serrations, wavy serrations, and square serrations, and the second serration portion 112 is disposed correspondingly to the first serration portion 111.

[0053] In the embodiments shown in Figures 2 and 3, the conductive pin 12 is fixed to the first end of the heating net 11, and the length direction of the conductive pin 12 is parallel to the length direction of the first end of the heating net 11. Furthermore, the first end of the heating net 11 is superimposed on a surface of the conductive pin 12 and can be fixed by welding. In this way, the first serration 111 on the first end is also correspondingly 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. The second serration 112 of another heating net 11 can abut against the docking bearing surface of the conductive pin 12 and dock with the first serration 111 at the same time.

[0054] In each pair of adjacent single-net assemblies 10, the second end of one heating net 11, with its second serrations 112, engages and butts with the first serrations 111 of the other heating net 11 along the circumferential direction of the cylindrical body. When the conductive pin 12 is connected to the first end of the heating net 11, the mating structure of the second serrations 112 and the first serrations 111 is also secured to the conductive pin 12.

[0055] Furthermore, as shown in FIG3 , the heating network 11 has two opposing ends, namely a third end and a fourth end. Each of the third and fourth ends is provided with a plurality of outwardly extending heat conducting portions 113 . Each heat conducting portion 113 is provided with fixing teeth 114 . These fixing teeth 114 can be inserted into the liquid guide member to relatively fix the liquid guide member and the heating network 11 , preventing random sliding during use or assembly in the atomizing device, thereby ensuring a consistent atomization effect of the atomizing device.

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

[0057] The heat conducting portion 113 may be a strip structure, and the fixing teeth 114 are provided on at least one side of the heat conducting portion 113, such as two opposite sides of the heat conducting portion 113 in Figure 3. The outer side of the heat conducting portion 113 away from the heating network 11 may also be provided with fixing teeth as needed.

[0058] The fixed teeth 114 on each side of the heat conducting portion 113 may be, but are not limited to, triangular saw teeth, wavy saw teeth, or square saw teeth, or may be a combination of triangular saw teeth, wavy saw teeth, and square saw teeth.

[0059] In the single-net assembly 10 of the present invention, the heating net 11 can be functionally divided into a heating zone 110, two connection zones 120 formed at opposite ends of the heating zone 110, and two heat conduction zones 130 formed at other opposite ends of the heating zone 110. The first and second ends of the heating net 11 respectively form the connection zones 120, and the third and fourth ends of the heating net 11 respectively form the heat conduction zones 130.

[0060] The heating area 110 is the main part of the heating net 11 and is in a grid shape. It can be a grid composed of diamond grids as shown in Figure 3, or it can be composed of other polygons such as quadrilateral grids, circular grids or elliptical grids, or it can be a grid structure composed of multiple combinations of the above. The heating area 110 is a Joule heat generation area. After power is turned on, the heating area 110 generates a large amount of heat. The heat can be dissipated to the surrounding area through the heat conduction area 130 under the action of heat conduction, thereby expanding the overall atomization area of ​​the heating net 11. The connection area 120 of the heating net 11 is used to connect the conductive pins 12 and the heating net 11.

[0061] In the embodiments shown in Figures 2 and 3 , the first and second ends of the heating net 11 are formed by edge heating strips of the heating area 110, respectively. The first and second serrated portions 111, 112 are formed on the sides of the corresponding edge heating strips. When the two heating nets 11 are docked together via the first and second serrated portions 111, 112, the edge heating strips where the first and second serrated portions 111 are located are docked with each other to form a complete rectangular strip structure.

[0062] As shown in FIG. 1 and FIG. 2 , preferably, the spliced ​​atomizer core 1 includes two single-net components 10 , which are connected end to end to form the cylindrical atomizer core shown in FIG. 1 .

[0063] During connection, the second end of the heating mesh 11 of the preceding single-mesh assembly 10 (the single-mesh assembly 10 on the right in Figure 2 ) is mated with the first end of the heating mesh 11 of the succeeding single-mesh assembly 10 (the single-mesh assembly 10 on the left in Figure 2 ). Specifically, the second serrations 112 of the second end are mated with the first serrations 111 of the first end through a concave-convex fit. This mating occurs at the conductive pin 12 of the succeeding single-mesh assembly 10. Then, the two single-mesh assemblies 10 are bent, and the second end of the heating mesh 11 of the succeeding single-mesh assembly 10 is mated with the first end of the heating mesh 11 of the preceding single-mesh assembly 10. Specifically, the second serrations 112 of the second end of the succeeding heating mesh 11 are mated with the first serrations 111 of the first end of the preceding heating mesh 11 through a concave-convex fit. This mating occurs at the conductive pin 12 of the preceding single-mesh assembly 10. In this manner, the two single-mesh assemblies 10 are joined to form a cylindrical atomizer core.

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

[0065] A conductive pin 12 is provided between two adjacent single mesh components 10 , and the first and second ends of the C-shape are butted against each other through the first and second serrated portions 111 , 112 , forming a closed cylindrical shape that can enclose the conductive pin 12 .

[0066] Specifically, as a preference, each single mesh assembly 10 may include a conductive pin 12, and the conductive pin 12 of each single mesh assembly 10 may be fixed inside the first end of the C-shaped heating mesh 11. When two single mesh assemblies 10 are connected to form a cylindrical atomizer core, the second end of the heating mesh 11 of the preceding single mesh assembly 10 and the first end of the heating mesh 11 of the succeeding single mesh assembly 10 are interlocked and docked with each other, that is, the first serrated portion 111 of the first end and the second serrated portion 112 of the second end are interlocked and docked with each other, so that the first end and the second end form a circular structure, while also enclosing the conductive pin 12 of the succeeding single mesh assembly 10 therein. The second end of the heating net 11 of the subsequent single-net component 10 is engaged with the first end of the heating net 11 of the previous single-net component 10, that is, the second serrated portion 112 of the second end of the subsequent heating net 11 is engaged with the first serrated portion 111 of the first end of the previous heating net 11, so that the second end and the first end form a circular structure, and at the same time, the conductive pin 12 of the previous single-net component 10 is enclosed therein.

[0067] 1 to 7 , the method for preparing the spliced ​​atomizer core of the present invention may include the following steps:

[0068] S1. Provide at least two single-net components 10, and connect the at least two single-net components 10 in sequence to form a splicing module, as shown in the structure of FIG2 .

[0069] Of the two opposite ends of the splicing module, one end is the first end of a heating net 11 with a conductive pin 12 and a first serrated portion 111 (as shown on the right side in Figure 2), and the other end is the second end of another heating net 11 with a second serrated portion 112 (as shown on the left side in Figure 2).

[0070] S2. Provide a welding positioning mold 20.

[0071] As shown in Figures 5 and 6, the mold cavity of the welding positioning mold 20 is a cylindrical cavity 21 (the radial cross-section is circular), and a welding opening 22 is provided on the side of the welding positioning mold 20, which is connected and extends axially along the cylindrical cavity 21. 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 configured according to the conductive pin 12 to accommodate and position the conductive pin 12. 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 place a conductive pin 12 on the splicing module into the positioning groove 23 for positioning. The opposite sides of the splicing module are spliced ​​at the welding opening 22 under the extrusion of the mold.

[0074] Taking the splicing module with two single mesh components 10 shown in Figure 2 as an example, when placed into the cylindrical cavity 21 of the welding and positioning mold 20, the conductive pin 12 located in the center is received and positioned within the positioning groove 23 of the circular cavity 21. The remaining portions of the two single mesh components 10 are attached to the inner surface of the cylindrical cavity 21, while the opposing ends of the single mesh components 10 (i.e., the first serrated portion 111 and the second serrated portion 112) are spliced ​​at the welding opening 22.

[0075] The splicing module is 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 the cylindrical cavity 21 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 center of the splicing module is accommodated and positioned within the positioning groove 23 of the cylindrical cavity 21. The rest of the splicing module fits against the inner surface of the cylindrical cavity 21, and the first and second serrated portions 111, 112 at opposite ends of the splicing module are spliced ​​together 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 is convenient for removing the atomizer core that has been spliced. In step S3, one end of the splicing module is passed through the welding opening 22 of the welding positioning mold 20 into the cylindrical cavity 21 and moved along the inner circumferential surface of the cylindrical cavity 21 until the first serrations 111 and the second serrations 112 at both ends of the splicing module are spliced ​​at the welding opening 22 under the extrusion 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 serrations 112 and the first serrations 111 at the splicing are connected as one and fixed to the conductive pin 12. Welding can be done by laser welding or butt welding.

[0079] 4 , when the first end and the second end of the heating net 11 of each single net assembly 10 are both C-shaped, in the above-mentioned preparation method, the steps of sequentially connecting the single net assemblies 10 to form a splicing module may specifically include:

[0080] The first end of one of the single mesh components 10 having a conductive pin 12 is butt-jointed and welded to the second end of the adjacent single mesh component 10 not having a 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 components 10 (i.e., between the first serration 111 and the second serration 112), thereby connecting the above-mentioned single mesh components 10 to form a splicing module.

[0081] The step of joining the opposite ends of the splicing module at the welding openings may further include:

[0082] The first end of one of the single mesh components 10 with the conductive pin 12 is connected to the second end of the adjacent single mesh component 10 without the conductive pin 12 through the serrated portion (i.e., the first serrated portion 111 and the second serrated portion 112) at the welding opening 22 of the welding positioning mold 20, and then connected into one by welding to form a cylindrical atomizing core.

[0083] The cylindrical atomizer core (i.e., the spliced ​​atomizer core 1) produced by the above-described preparation method can be removed from the welding and positioning mold 20 by moving axially along the cylindrical cavity 21 and sliding out of the open end of the welding and positioning mold 20. Alternatively, if the welding and positioning mold 20 is formed by axially butting two unit molds together, the two unit molds can be disassembled to remove the cylindrical atomizer core.

[0084] After the spliced ​​atomizer core 1 of the present invention is assembled with the liquid guide member, an atomizer module is formed, which is suitable for use in an atomizer device or an electronic cigarette.

[0085] As shown in Figure 8, in the atomizer module, the liquid guide 30 fills the interior of the spliced ​​atomizer core 1 or wraps around the outer periphery of the spliced ​​atomizer core 1. When the spliced ​​atomizer core 1 has fixed teeth 114, the fixed teeth 114 are inserted into the liquid guide 30 to fix the spliced ​​atomizer core 1 and the liquid guide 30 relative to each other.

[0086] 3 and 8 , in the spliced ​​atomizer core 1, the fixed teeth 114 on the heating mesh 11 form an angle with the heating mesh 11, meaning the fixed teeth 114 have a certain tilt angle on the heating mesh 11. After the spliced ​​atomizer core 1 is filled with the liquid guide 30, the fixed teeth 114 with the tilt angle will be inserted into the liquid guide 30, which fixes the atomizer core in place within the cotton and provides closer contact with the liquid guide 30, ensuring that external e-liquid flows smoothly through the liquid guide 30 into the atomizer core surface during use.

[0087] The liquid-conducting member 30 can be a liquid-conducting cotton made of cotton material, or a liquid-conducting member made of porous materials such as fibers.

[0088] Furthermore, referring to Figures 8 and 9, the atomization module of the present invention may also include a liquid storage cotton 40, which is wrapped around the outer periphery of the spliced ​​atomization core 1. The liquid guide 30 and the liquid storage cotton 40 form an inner and outer wrapping of the spliced ​​atomization core 1. The fixing teeth 114 on the heating network 11 can also be inserted into the liquid storage cotton 40, so that the spliced ​​atomization core 1 and the liquid storage cotton 40 are relatively fixed. Thus, the liquid guide 30, the spliced ​​atomization core 1, and the liquid storage cotton 40 form a relatively fixed module, avoiding random sliding during use or assembly to the atomization device, and ensuring the consistency of the atomization effect of the atomization device.

[0089] Furthermore, referring to Figures 1 and 2 , the atomizer device of the present invention includes the above-mentioned spliced ​​atomizer core 1. Alternatively, referring to Figures 8 to 10 , the spliced ​​atomizer core 1 is used in the atomizer device as an atomizer module.
