Description

[0002] With the rapid development of atomization technology, atomization products such as electronic cigarettes have become a part of people's daily life. As one of the common atomization core materials, cotton core has attracted widespread attention for its good liquid absorption and cost advantages. At present, the cotton core on the market generally uses a heating mesh with pins at both ends, which is curled and placed on the inner wall of the oil-conducting cotton layer. The pins extend to the lower end and are placed on the inner and outer walls of the silicone tube respectively. Then the formed oil-conducting cotton and heating mesh are placed in the atomization tube. Since the volume of the oil-conducting cotton layer will expand after the oil is injected, and the mesh is thin, especially the conductive sheets on both sides of the heating mesh, it is easy to deform under the extrusion of the oil-conducting cotton layer, resulting in poor electronic cigarette atomization effect.

[0023] To make the purposes, technical solutions and advantages of the disclosed embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0025] The electronic cigarette includes a battery module (not shown in the figure), an oil cup assembly (not shown in the figure) and an atomization assembly 100. The atomization assembly 100 and the oil cup assembly are combined to form an atomizer body. The oil cup assembly contains e-liquid. The atomization assembly 100 is fixed in the middle of the oil cup. The atomization assembly 100 can heat and atomize the e-liquid to generate smoke. An integrated cotton is also filled on the outer peripheral side of the atomization assembly 100. The integrated cotton is a plant fiber with strong oil absorption ability. The e-liquid is locked in the integrated cotton, reducing the fluidity of the e-liquid and the risk of liquid leakage from the atomization device.

[0026] The present disclosure provides an atomization assembly including an atomization bracket 3 with a hollow interior, a liquid guide 2 and a heating mesh 1. The atomization bracket 3 is a cylindrical tube with a hollow interior. The heating mesh 1 is laid flat on the inner side wall of the liquid guide 2. The liquid guide 2 is formed by laminating several layers of sheet-shaped cotton cloth. The liquid guide 2 and the heating mesh 1 are curled into a C shape and embedded in the atomization bracket 3. A plurality of oil inlet holes 31 are provided at intervals along the outer peripheral side of the middle part of the atomization bracket 3. The oil inlet holes 31 are communicated with the oil cup. The cotton cloth has a good liquid guiding rate due to its large porosity, so the e-liquid in the oil cup can be transmitted to the heating mesh 1.

[0027] Please refer to Figure 2 and Figure 3, the heating mesh 1 includes an upper heating monomer 11 and a lower heating monomer 12 which are distributed vertically, a common conductive part 13, a first conductive part 14, a second conductive part 15, a common pin 17 and two independent pins 18. The common pin 17 is vertically installed on the common conductive part 13. The common conductive part 13 is arranged at the same end of the upper and lower heating monomers, and connects and combines these two heating monomers together. The second conductive part 15 is arranged at one end of the upper heating monomer 11 away from the common conductive part 13, and the second conductive part 15 is arranged at one end of the lower heating monomer 12 away from the common conductive part 13. A number of first hollow parts 143 are provided on the first conductive part 14 and / or the second conductive part 15. The two independent pins 18 are respectively fixed on the first conductive part 14 and the second conductive part 15, and these two independent pins 18 are staggeredly distributed. The first conductive part 14 and the second conductive part 15 are metal sheets, and a plurality of hollow parts are provided on the metal sheets. The hollow parts provide expansion space for the liquid conductor 2 after oil injection, so as to slow down the problem that the heating mesh 1 is deformed due to the expansion and extrusion of the liquid conductor 2, and further ensure the atomization effect of the electronic cigarette.

[0028] The two heating monomers arranged vertically can be heated alternately, generating less carbon deposition than a single heating monomer, effectively alleviating the problem of carbon deposition on the heating mesh 1, and also extending the service life of the atomization component 100; the two heating meshes 1 can also be heated simultaneously, increasing the heating area and improving the atomization amount. The single-shot mode and the dual-shot mode expand the working mode of the heating mesh 1, solving the problem of the single heating method of the existing single heating monomer.

[0029] In one embodiment, the upper heating monomer 11 and the lower heating monomer 12 have the same size, shape and resistance value to ensure the consistency of the atomization effect when the two heating monomers work independently. As Figure 3 shown, the width of the first conductive part 14 is greater than the width of the second conductive part 15, and the two independent pins 18 arranged on these two conductive parts extend downward and are spaced apart. That is, without changing the heating area of the two heating monomers, by changing the widths of the first conductive part 14 and the second conductive part 15, and making the two independent pins 18 respectively at the outermost ends of the first conductive part 14 and the second conductive part 15, the spaced distribution of the two independent pins 18 is realized, so as to reduce the risk of short circuit between the independent pins 18 and not affect the heating effect when switching the heating mesh 1.

[0030] In one embodiment, the first conductive part 14 includes two spaced-apart and vertically arranged conductive segments 141 and a plurality of connecting segments 142 disposed between the two conductive segments 141. The plurality of connecting segments 142 are spaced apart along the height direction of the conductive segments 141, and each connecting segment 142 is perpendicular to the two conductive segments 141 respectively. Then, the two conductive segments 141 and the plurality of connecting segments 142 enclose a rectangular first hollow part 143, and one of the independent pins 18 is welded to the outermost conductive segment 141. A plurality of first hollow parts 143 are provided on the first conductive part 14, so that the expanded partial liquid guide 2 can be embedded into the first hollow part 143, thereby slowing down the deformation of the heating mesh 1 caused by the excessive expansion and extrusion of the liquid guide 2. The first hollow part 143 can increase the oil inlet area and improve the overall oil inlet speed of the atomization assembly 100. Of course, in some embodiments, a plurality of hollow holes can also be formed on the second conductive part 15, and the shape of the hollow holes is not limited to a rectangle, and can also be a circle, an ellipse, a quadrilateral, a triangle, etc.

[0031] Further, a plurality of second hollow parts 16 are spaced apart on the common conductive part 13. The hollow parts provide an expansion space for the liquid guide 2 after oil injection, thereby slowing down the problem of deformation of the heating mesh 1 caused by the expansion and extrusion of the liquid guide 2, and further ensuring the atomization effect of the electronic cigarette.

[0032] The above are only the specific embodiments of the present invention, enabling those skilled in the art to understand or implement the present disclosure. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
