Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an atomizing core and an electronic cigarette. Background Technology

[0002] Electronic cigarettes, also known as virtual cigarettes, are a common type of electronic product that simulates traditional cigarettes. They primarily produce "smoke" by atomizing e-liquid. Because e-cigarette liquids or pastes do not contain harmful substances such as nicotine or tar, they serve as a smoking cessation aid or a substitute for traditional cigarettes. Common e-cigarette atomizing coil structures include vertical cotton wick structures, flat ceramic wick structures, and horizontal cotton wick structures.

[0003] Horizontal cotton wick atomizer coils have been gradually phased out of the market due to severe leakage. Vertical cotton wick atomizer coils have the advantages of long atomization life and good hole feel, but the cotton wicks are easily deformed during assembly, making it difficult for personnel to ensure the consistency of the atomizer coils during assembly, resulting in inconsistent hole feel in the atomized vapor. In addition, the vertical cotton wick atomizer coil structure of liquid e-liquid atomizers is more complex and more expensive. Flat ceramic wick atomizer coils are small in size and easy to assemble, but ceramic wicks have a relatively short life and can generally only be used in 2ml atomizers. Utility Model Content

Detailed Implementation

[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Please see Figures 1-8 In this embodiment of the present invention, an atomizing core 100 includes:

[0032] The mesh fixing bracket 1 has two mounting holes 11 that pass through its top and bottom;

[0033] Metal electrode 2, there are two metal electrodes 2, and the two metal electrodes 2 are respectively inserted into the two mounting holes 11;

[0034] Oil-wicking cotton 3 is placed on top of the mesh fixing bracket 1;

[0035] The mesh heating wire 4 is disposed between the oil-guiding cotton 3 and the mesh fixing bracket 1. The mesh heating wire 4 includes a mesh-shaped heating part 41 and heating wire tabs 42 connected to both ends of the heating part 41. The two heating wire tabs 42 are respectively connected to the metal electrode 2.

[0036] The heating wire tabs 42 on the mesh heating wire 4 are connected to the metal electrode 2 by welding and / or riveting. When the atomizing core 100 is working, the current is evenly conducted to the mesh heating wire 4 through the metal electrode 2. After the mesh heating wire 4 becomes conductive, the heating part 41 starts to heat up and atomize the atomizing liquid on the oil-wicking cotton 3 into smoke. The heating part 41 is mesh-shaped, which ensures that the atomizing core 100 is heated evenly during operation, and that the atomizing liquid is fully atomized. The oil-wicking cotton 3 is in close contact with the mesh heating wire 4, which can ensure that the atomizing liquid on the mesh heating wire 4 is always adequately supplied, thus ensuring that the taste of the atomized smoke remains consistent.

[0037] An atomizing hole 12 is provided at the top center of the mesh fixing bracket 1, extending to the bottom of the mesh fixing bracket 1. The smoke generated by atomization can flow out quickly through the atomizing hole 12.

[0038] In order to better fix the heating wire 4 of the mesh to the mesh fixing bracket 1, the top of the mesh fixing bracket 1 is provided with multiple limiting blocks 13 on the outer periphery of the mounting hole 11, and the multiple limiting blocks 13 form a mounting position, in which the heating wire tab 42 is set.

[0039] The heating element 41 includes a plurality of rhomboid heating elements 43. At least one side of each heating element 43 is connected to an adjacent heating element 43 to form the heating element 41. Each heating element 43 has an opening 44 extending through its top and bottom in the middle. The opening 44 divides the heating element 43 into a first heat-conducting part 45 and a second heat-conducting part 46. A heat-conducting strip 47 is provided at the connection between the first heat-conducting part 45 and the second heat-conducting part 46. The two ends of the opening 44 form an included angle of 25° to 30°. There are 5 heating elements 43. Except for the heating elements at the end and the beginning, which are connected to the adjacent heating elements on only one side, the other heating elements are connected to the adjacent heating elements 43 on both sides. The heating elements 43 have the same shape to ensure uniform heating and facilitate complete heating. Furthermore, the smoke generated by atomization can flow out quickly through the opening 44. In addition, the heat-conducting strip 47 is provided so that when the power is on, the heat generated by the heating elements 43 will be transferred to the heat-conducting strip 47, increasing the heating area and improving the atomization effect.

[0040] This utility model also provides an electronic cigarette 200, including an electronic cigarette body 5 and an atomizing core 100 as described above. The electronic cigarette body 5 has an atomizing liquid chamber 51 and a smoke outlet chamber 52. Below the smoke outlet chamber 52, the electronic cigarette body 5 also has an atomizing shell, which includes an upper shell 53 and a lower shell 54. The upper shell 53 and the lower shell 54 are engaged to form an atomizing chamber 55. The upper shell 53 has a smoke outlet channel 56 communicating with the atomizing chamber 55. The top center of the upper shell 53 has an opening for the smoke outlet channel 56. The upper shell 53 has a smoke outlet 57 and a smoke outlet chamber 52 that communicates with the smoke outlet 57. The inner top wall of the upper shell 53 is provided with an installation groove 58 that communicates with the atomizing chamber 55. The atomizing core 100 is placed in the installation groove 58. The top of the upper shell 53 and on both sides of the smoke outlet 57 are provided with liquid inlet holes 59 that communicate with the installation groove 58. The atomizing liquid chamber 51 communicates with the liquid inlet holes 59. The lower shell 54 is provided with two conductive electrodes 510, which are respectively connected to the two metal electrodes 2 of the atomizing core 100.

[0041] During use, the atomizing liquid stored in the atomizing liquid chamber 51 enters the mounting groove 58 through the liquid inlet hole 59, wetting the oil-guiding cotton 3. The atomizing core 100 is turned on and the current is conducted to the mesh heating wire 4 through the metal electrode 2. After the mesh heating wire 4 becomes conductive, the heating part 41 starts to heat up and atomizes the atomizing liquid on the oil-guiding cotton 3 into smoke. The smoke generated by atomization enters the atomizing chamber 55 through the atomizing hole 12, then flows into the smoke outlet chamber 52 through the smoke outlet duct 56 and the smoke outlet hole 57, and finally flows out through the smoke outlet chamber 52.

[0042] In order to better connect the upper shell 53 and the lower shell 54, slots 511 are provided on both sides of the upper shell 53. The slots 511 contain right-angled trapezoidal locking blocks 512. The top sides of the lower shell 54 are provided with plug blocks 513 for inserting and engaging with the slots 511. The plug blocks 513 are provided with slots 514 for engaging with the locking blocks 512.

[0043] The top of the upper shell 53 is provided with a top cover 515, and the outer periphery of the top cover 515 is provided with a sealing protrusion 516. The top of the top cover 515 is provided with a clearance hole 517 that exposes the smoke outlet 57 and the liquid inlet 59. The outer periphery of the lower shell 54 is provided with multiple circumferential grooves, and a sealing ring 518 is fitted inside the circumferential grooves. Through the arrangement of the top cover 515, the sealing protrusion 516 and the sealing ring 518, the sealing performance between the upper shell 53 and the electronic cigarette body 5, as well as between the lower shell 54 and the electronic cigarette body 5, can be improved.
