Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic cigarette technology, and in particular relates to an atomizing heating mesh, an electronic atomizing device, and an electronic cigarette. Background Technology
[0002] The principle of thermal atomization is to rapidly heat the liquid on the surface of the liquid-conducting cotton to the azeotropic temperature range through a mesh heating element, and then carry the atomized droplets out through airflow. Existing mesh heating elements are generally made of alloy sheets with high resistivity, which are processed into a mesh structure through stamping and chemical etching. The transverse wavy alloy filaments are generally composed of 6-10 V-shaped structures, with longitudinal fine lines extending from the bottom and top of the transverse V-shapes. If there are two or more transverse wavy lines, multiple sets of hexagonal hole structures are formed on the mesh heating element. The width and thickness of the longitudinal and transverse wavy filaments are evenly distributed. The whole can be heated quickly, is corrosion resistant, and can be adapted to various heating power and atomization amount design requirements. However, since the heat conduction in the middle part of the heating area is only through the heat transfer zone connected to it, while the heat conduction in the heating areas on both sides can also be quickly conducted to the non-heated edges and electrode leads (i.e., conductive electrodes) in addition to the heat transfer zone connected to it, the existing mesh heating elements generally have the following problems: uneven temperature distribution of the mesh heating elements (the temperature in the middle of the mesh heating element is relatively high, while the temperature on both sides is relatively low), which makes the oil-guiding cotton in the middle of the atomizer prone to aging (and the high temperature in the middle can easily cause thermal decomposition of the atomized liquid, forming harmful substances). In addition, the surface of the existing heating mesh is flat, which makes the surface area in contact with the oil-guiding cotton small, which is not conducive to improving atomization efficiency and the even distribution of heat. Utility Model Content
[0003] To solve the above-mentioned technical problems, one of the objectives of this utility model is to provide an atomizing heating mesh with a simple structure and a large specific surface area.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: an atomizing heating mesh, comprising:
[0005] Two conductive electrodes are provided, which are arranged longitudinally and spaced apart laterally.
[0006] A heating mesh section is disposed between the two conductive electrodes, and its two sides are connected to or integrally formed with the two conductive electrodes;
[0007] The surface of the heating mesh is rough.
[0008] The beneficial effects of this utility model are as follows: by setting a rough surface on the entire heating mesh, the specific surface area of the heating mesh is increased. This not only helps to improve heat dissipation and avoid local high temperatures, but also increases the contact area between the heating mesh and the oil-guiding cotton, thereby resulting in better atomization.
[0009] Based on the above solution, the present invention can be further improved as follows:
[0010] Furthermore, the heating mesh section includes:
[0011] The heating element has two heating elements, which are arranged laterally between the two conductive electrodes and longitudinally spaced between the two conductive electrodes. The two ends of each heating element are electrically connected to the two conductive electrodes respectively.
[0012] The heat dissipation section includes multiple first heat dissipation sections and multiple second heat dissipation sections. On the side of each of the two heat dissipation sections that are opposite to each other, multiple first heat dissipation sections are arranged longitudinally and spaced laterally. Each first heat dissipation section is connected to or integrally formed with the corresponding heat dissipation section. Between each of the two heat dissipation sections, multiple second heat dissipation sections are arranged longitudinally and spaced laterally. The two ends of each second heat dissipation section are connected to or integrally formed with the two heat dissipation sections respectively.
[0013] Both the heating element and the heat dissipation element have rough surfaces.
[0014] The beneficial effects of the above technical solution are as follows: the second heat dissipation part is connected with the two heat-generating parts to form a mesh structure, and the first heat dissipation part and the second heat dissipation part work together to dissipate heat from the heat-generating parts. This allows the heat to be quickly diffused to the oil-wicking cotton, and avoids the local heat accumulation that leads to high temperature and aging of the oil-wicking cotton.
[0015] Furthermore, the heating element is wavy.
[0016] The beneficial effects of the above technical solution are that it increases the specific surface area of the heating element and makes the length of the entire heating mesh adjustable in the transverse direction.
[0017] Furthermore, the two heating elements are a first heating element and a second heating element, with the peak of the first heating element aligned with the trough of the second heating element, and the peak of the second heating element aligned with the trough of the first heating element.
[0018] The beneficial effect of the above technical solution is that it makes the structure of the entire heating mesh more aesthetically pleasing.
[0019] Furthermore, the first heat dissipation part is provided at both the peak of the first heating part and the trough of the second heating part; and / or the trough of the first heating part and the peak of the second heating part are connected by the second heat dissipation part at their alignment.
[0020] The beneficial effects of the above technical solution are that it makes the entire heating mesh structure aesthetically pleasing and provides excellent heat dissipation.
[0021] Furthermore, the width of the plurality of first heat dissipation parts located in the middle in the horizontal direction is greater than the width of the remaining plurality of first heat dissipation parts; and / or the width of the plurality of second heat dissipation parts located in the middle in the horizontal direction is greater than the width of the remaining plurality of second heat dissipation parts.
[0022] The beneficial effect of the above technical solution is that it makes the heat dissipation effect of the heating mesh in the middle of the horizontal direction better, and avoids the temperature in the middle being higher than that on both sides, which would cause the oil-guiding cotton to age.
[0023] Furthermore, the heat dissipation part is rectangular, trapezoidal, or T-shaped.
[0024] The advantages of the above technical solution are that it has a simple structure and good heat dissipation.
[0025] Furthermore, the surface roughness R of the heating mesh is 2-3 μm.
[0026] The beneficial effect of the above technical solution is that it increases the specific surface area while meeting the performance requirements.
[0027] The second objective of this invention is to provide an electronic atomizing device with a simple structure and good atomization effect.

[0039] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0040] This embodiment provides an electronic cigarette, including an electronic atomizing device, and another embodiment provides an electronic atomizing device including an atomizing heating mesh, such as... Figures 1-4 As shown, the core improvement of this embodiment lies in providing an atomizing heating mesh, which includes a conductive electrode 1 and a heating mesh 2. Two conductive electrodes 1 are provided, arranged longitudinally and spaced laterally. The heating mesh 2 is disposed between the two conductive electrodes 1, and its two sides are connected to or integrally formed with the two conductive electrodes 1. The surface of the heating mesh 2 is roughened. By making the entire surface of the heating mesh roughened, the specific surface area of the heating mesh is increased. This improves heat dissipation and avoids localized high temperatures, and also increases the contact area between the heating mesh and the oil-guiding cotton, resulting in better atomization.
[0041] like Figure 1As shown, the heating mesh section 2 includes two heating elements 21, which are arranged laterally between the two conductive electrodes 1 and longitudinally spaced between them. Each heating element 21 has two ends electrically connected to the two conductive electrodes 1. The heating mesh section 2 also includes a heat dissipation section 22, comprising multiple first heat dissipation elements 22a and multiple second heat dissipation elements 22b. On the opposite sides of the two heating elements 21, multiple first heat dissipation elements 22a are longitudinally arranged and laterally spaced. Each first heat dissipation element 22a is connected to or integrally formed with a corresponding heating element 21. Between each heating element 21, multiple second heat dissipation elements 22b are longitudinally arranged and laterally spaced. Each second heat dissipation element 22b has two ends connected to or integrally formed with the two heating elements 21. The surfaces of both the heating elements 21 and the heat dissipation sections 22 are rough surfaces. This allows the second heat dissipation section to connect with the two heating sections to form a mesh structure, while the first and second heat dissipation sections work together to dissipate heat from the heating sections. This allows the heat to spread quickly to the oil-wicking cotton and prevents local heat accumulation that could lead to high temperatures and cause the oil-wicking cotton to age.
[0042] like Figure 1 As shown, the heating element 21 is wavy, which increases the specific surface area of the heating element and makes the length of the entire heating mesh adjustable in the lateral direction. The two heating elements 21 are the first heating element 21a and the second heating element 21b. The peak of the first heating element 21a is aligned with the trough of the second heating element 21b, and the peak of the second heating element 21b is aligned with the trough of the first heating element 21a, which makes the structure of the entire heating mesh more aesthetically pleasing.
[0043] The first heat dissipation part 22a is provided at the peak of the first heating part 21a and the trough of the second heating part 21b; the second heat dissipation part 22b is connected at the trough of the first heating part 21a and the peak of the second heating part 21b where they are aligned with each other, so that the structure of the entire heating mesh is aesthetically pleasing and its heat dissipation effect is good.
[0044] The width of the multiple first heat dissipation sections 22a located in the middle horizontally is greater than the width of the remaining multiple first heat dissipation sections 22a (preferably, the width of the multiple first heat dissipation sections 22a located in the middle horizontally is 2-5 times the width of the remaining first heat dissipation sections 22a); the width of the multiple second heat dissipation sections 22b located in the middle horizontally is greater than the width of the remaining multiple second heat dissipation sections 22b (preferably, the width of the multiple second heat dissipation sections 22b located in the middle horizontally is 2-5 times the width of the remaining second heat dissipation sections 22b); this makes the heat dissipation effect of the heating mesh section better in the middle region horizontally, and avoids the temperature in the middle being higher than the temperature on both sides, which would cause the oil-guiding cotton to age.
[0045] The heat dissipation part 22 is rectangular, trapezoidal, or T-shaped; it has a simple structure and good heat dissipation effect.
[0046] The surface roughness Ra of the heating mesh 2 is 2-3 μm, which increases the specific surface area while meeting performance requirements.
[0047] like Figure 1 As shown, two heating elements, two conductive electrodes, and multiple second heat dissipation elements together form a plurality of sequentially distributed hexagonal frames. The first and second heat dissipation elements corresponding to the two hexagonal frames on each side are widened. The first and second heat dissipation elements located in the middle can be rectangular (e.g., ...). Figure 1 (as shown), trapezoidal (as shown) Figure 2 As shown and Figure 3 ), T-shaped ( Figure 4 The first heat dissipation section is T-shaped, while the second heat dissipation section consists of two T-shaped sections joined together. This can be achieved by at least one of the following or any combination: (e.g., a rectangle with a tapered waist). Figure 3 (Second heat dissipation section) or waist expansion (such as) Figure 2 (Second heat dissipation section).
[0048] in, Figures 1-4 Both the first and second heat dissipation sections with the shading in the middle are widened.
[0049] In this embodiment, the heating element of the heating mesh has a lower resistance, while the central region along its length generates more heat and its temperature is significantly higher than that at its ends. To avoid uneven temperature distribution throughout the heating mesh, it is necessary to improve the heat dissipation performance of the central region. Therefore, in this embodiment, the surfaces of the central region of the heating element and the multiple heat dissipation elements located in the center are roughened (e.g., ...). Figures 1-4 The areas with filled shadows are roughened.
[0050] In this embodiment, the roughening treatment of the heating mesh can be achieved through laser etching, sandblasting, or other methods. After roughening, the heating mesh can carry more liquid on both sides of the central region, thereby balancing the atomization temperature.
[0051] In this embodiment, the first heat dissipation section of the heating mesh does not form a closed loop, so no current flows through it and it does not participate in the heating process. It only serves as a support and heat dissipation function. The second heat dissipation section connects the two heating sections. Although it has resistance and forms a current loop, the potential difference between the two ends of each section of the second heat dissipation section is close to 0, forming a balanced bridge. Basically no current flows through it, so there is no heating phenomenon. It also serves as a heat dissipation and support function.
[0052] In this embodiment, the e-liquid on the surface of the heating mesh directly affects the achievement of a balanced and stable atomization temperature during the atomization process. Currently, the material of the heating mesh can be a nickel-chromium alloy, an iron-chromium-aluminum alloy, a titanium alloy, or stainless steel, and the material of the conductive electrode can be nickel or aluminum alloy (its diameter can be 0.2-0.5 mm). The metal is smelted, hot-rolled, and cold-rolled into a thin metal strip, and then fully etched (etching depth 2-4 μm; surface roughness Ra: 2-3 μm; etched surface is a uniform and fine uneven surface) or stamped into a metal mesh.
[0053] In this embodiment, the heating mesh has good atomization temperature consistency, which can avoid dry burning and burning of the cotton; at the same time, the continuous generation of smoke during the customer's inhalation is extended, improving the taste of the smoke.
[0054] This embodiment also provides six different specifications of atomizing heating mesh, with the comparative example being existing conventional heating mesh (such as...). Figure 5 As shown in Table 1), the width of the heat dissipation part is consistent and is 0.15 mm. Its surface roughness is 0.15 μm and its resistance is 0.8246 Ω. In Examples 1 to 7, the multiple first heat dissipation parts and multiple second heat dissipation parts in the middle are widened as shown in Table 1. At the same time, the surface roughness and resistance values are also as shown in Table 1. The atomized heating mesh of the comparative example and the examples were heated and tested. The temperature at eight points (points a, b, c, d, e, f, g, and h) was measured (the heating mesh is taken as having a structure with eight hexagonal holes). The specific results are shown in Table 2. The schematic diagrams of Examples 1 to 7 are shown in Table 2. Figure 1 As shown.

[0058] Table 2
[0059]
[0060] As shown in Table 1, although the heat dissipation section in the middle of each example is widened, its resistance and power remain basically unchanged. By detecting the temperature at each trough of the first heating section and the atomization temperature, it was found that the temperature at points c, d, e and f in the central area is significantly reduced. It can be seen that by increasing the surface area of the heat dissipation section, the temperature of the entire heating mesh can be made relatively uniform.
[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
