Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an atomizing component and its electronic cigarette. Background Technology

[0002] Electronic atomization technology involves heating a liquid substance to its boiling point to produce vapor, which then mixes with air to form an aerosol. Atomizing components typically consist of a heating element and a liquid conductor. The heating element generates heat when electricity is applied, while the liquid conductor conducts the liquid. Currently, electronic atomization is primarily used in the e-cigarette industry; however, with the development of this technology, its applications extend beyond e-cigarettes, encompassing medical, beauty, and daily necessities fields such as steam beauty devices and home humidifiers, demonstrating a wide range of applications. Currently, the industry mainly uses porous ceramics and liquid-conducting cotton as the liquid-conducting materials. Both materials have their advantages and disadvantages. Porous ceramics offer advantages such as good structural strength and ease of assembly, but their inconsistent micropore size and uncontrollable micropore size distribution lead to numerous shortcomings in practical applications. Liquid-conducting cotton is currently the most widely used material in the e-cigarette industry, but it has low temperature resistance, is prone to shrinkage and carbonization, and its microporous structure is affected by compression, resulting in uncontrollable oil conduction rates. Furthermore, its consistency is poor during mass production, and it is significantly affected by process factors. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an atomizing component and its electronic cigarette; the liquid guiding structure of the atomizing component is controllable, simple, stable and reliable.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] The atomizing component includes a liquid guiding sheet and a heating sheet; the liquid guiding sheet is a sheet-like body with multiple micropores; the heating sheet has multiple mesh-like parts, which are connected by connecting parts; the connecting parts are bent so that the mesh-like parts are opposite to each other; the liquid guiding sheet is attached to the outside of the mesh-like parts and corresponds to the micropore area of ​​the liquid guiding sheet.

[0006] The heating element has two mesh sections, which are parallel to each other after the connecting part is bent.

[0007] The heating element has four mesh sections, and the connecting part is bent to form two relatively parallel planes, with two mesh sections on each plane.

[0008] The micropores are provided in the mesh section; the micropore diameter range is 1-100um, preferably 3-20um.

[0009] The electronic cigarette also includes an oil tank and a silicone base; the atomizing component is inserted into the silicone base; the silicone base is set in the oil tank; the side of the silicone base is provided with an oil inlet corresponding to the micropores of the liquid guiding plate, and the e-liquid in the oil tank can seep into the mesh part of the heating element through the oil inlet and the micropores.

[0010] The silicone seat has an axial groove extending downwards from the top; the atomizing component is axially inserted into the groove.

[0011] This invention utilizes laser-induced etching to create multiple micron-sized micropores on a dense glass or ceramic sheet, employing these micropores as liquid channels. A heating element with heating circuitry is then formed on a planar metal sheet using etching, stamping, or laser techniques. This heating element is then attached to the microporous glass sheet, using the micropores to guide the liquid and the heating element to atomize the vapor. The micropore size of this atomizing component is controllable, allowing for the selection of different pore sizes based on different atomizing liquids, ensuring stability and reliability. Compared to traditional oil-retaining cotton and porous ceramics, the flavor is purer. The atomizing component possesses a certain strength and dimensional accuracy, and is simple, convenient, and reliable to assemble. The atomizing component can be bent at any angle through the heating element's connection point, similar to the principle of a folding screen. The heating element is made of metal, and with the glass sheet as support, a thinner heating element can be used compared to cotton-based atomizing cores, supporting lower power. The heating element is bent into a double-sided structure, with vertical airflow for atomized vapor, resulting in superior flavor and atomization volume compared to horizontal placement and single-sided heating structures. Both the heating element and the microporous glass sheet are planar structures, which can be mass-produced in an array and then cut into individual units, resulting in high production efficiency and high dimensional accuracy.

[0028] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.

[0029] like Figures 1 to 15 As shown, the atomizing component of this utility model includes a liquid guiding sheet 1 and a heating element 2.

[0030] The liquid guiding sheet 1 can form multiple micropores 11 on a glass substrate. The thickness of the glass substrate is generally between 0.1-3 mm, preferably 0.4-1.0 mm, and the material can be silica glass or borate glass, etc.; or a ceramic substrate can also be used. The substrate material must have characteristics such as high temperature resistance, insulation, and supporting strength. Multiple micron-sized pores are formed on the substrate through processing, with a pore size ranging from 1-100 μm, preferably 3-20 μm. The size of the micropores 11 is not absolute. If the substrate sheet is thicker, the selected pore size needs to be larger, and if the substrate sheet is thinner, it can be smaller. Or, if the viscosity and surface tension of the atomized liquid are different, different thicknesses and micropore sizes can be selected. The micropores 11 can be processed by laser forming or laser-induced etching. The principle is to change the material at the substrate by laser energy, and then remove the part of the material treated by the laser energy by a corresponding etching solution to form micropores. The size of the micropores 11 can be adjusted by adjusting the size of the laser beam. The distribution of micropores can be a regular, linear distribution or an irregular distribution, such as more micropores in the heating area and fewer in other areas, or micropores of different sizes and densities depending on the temperature of the heating area.

[0031] The heating element 2 has multiple mesh-like sections 21, which are connected by connecting sections 22. Specifically, the heating element 2 is a sheet structure with heating circuitry formed from a metal sheet through etching, laser cutting, or stamping. The material is generally made of iron-chromium-aluminum alloy, nickel-based alloy, stainless steel, titanium, or titanium alloy. The sheet thickness is typically between 0.005-0.2 mm. After removing certain areas, the thinner sections of the heating element have higher resistance. When current passes through, heat is generated due to the resistance heating effect; the atomization area typically requires a temperature of 200-300℃.

[0032] The atomizing component of this invention consists of at least two microporous glass substrates and one heating element 2. The glass substrates are spaced apart and connected by a connecting part 22 of the heating element. Micropores 11 are formed on the glass substrates to guide oil, and the glass substrates support the heating element 2 to prevent deformation. The heating element 2 has hollowed-out heating circuits, and the heating element 2 generates heat to atomize the e-liquid seeping from the micropores 11. The heating element 2 connects the two glass substrates. The connection between the heating element 2 and the glass substrates can be achieved by bonding, welding, laser welding, or other methods.

[0033] After the liquid guide plate 1 and the heating element 2 of the atomizing assembly are bonded together, the middle part can be bent and deformed through the connecting part 22 of the heating element 2, so that the heating elements are facing each other. The outer side is the oil inlet surface, and the surface of the heating element that is bonded to the microporous glass sheet is the atomizing surface. The heating areas of the heating elements 2 are facing each other, and the glass sheets are preferably parallel, but they can also be at a certain angle.

[0034] like Figures 11 to 15As shown, the atomizing component can be composed of different numbers of heating elements 2, or it can be bent by the connecting part 22 to form different shapes of atomizing components.

[0035] See Figure 10 As shown, the electronic cigarette of this utility model also includes an oil tank 3 and a silicone seat 4. An axial groove 41 is formed in the center of the silicone seat 4, extending downwards from the top. The atomizing component is axially inserted into the groove 41. The silicone seat 4 is disposed within the oil tank 3; an oil inlet 42 is provided on the side of the silicone seat 4 corresponding to the micropores 11 of the liquid guiding plate 1, allowing e-liquid in the oil tank 3 to seep into the mesh portion 21 of the heating element 2 through the oil inlet 42 and the micropores 11, thereby forming an oil supply path for the heating element 2.

[0036] The aforementioned sealing seat 4 is made of silicone material, or it can be made of high-temperature resistant plastic, liquid silicone or ceramic through in-mold injection molding.

[0037] After the atomizing component is installed in the sealing seat 4, only the oil inlet surface of the heating element 2 contacts the e-liquid, while the other parts are sealed. The e-liquid passes through the micropores of the glass plate to reach the atomizing surface and is heated into atomized vapor by the heating element 2. When inhaling, air enters from below, is atomized by the heating element 2, and is then drawn out as atomized vapor from the mouthpiece 31 formed at the top of the oil tank 3.

[0038] The structure of the remaining parts of the electronic cigarette of this utility model only needs to be adapted to the aforementioned structure; for those skilled in the art, it can be achieved without creative effort; therefore, it will not be described in detail here.
