Description

Technical Field

[0001] The present application relates to the technical field of electronic cigarettes, and in particular to an atomization structure and an electronic cigarette. Background Art

[0002] Existing boat-shaped atomizer structures are typically fixed with a connecting rod. This requires a metal rod as a framework, around which the heating wire is spirally wound, and then the entire structure is placed in the e-liquid. The heating wire itself is flexible and has no fixed shape, so it relies on the central metal rod for mechanical support and defines the final heating shape, such as the boat shape. This structure results in slower e-liquid atomization when the heating wire is heated. Summary of the Invention

[0028] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0029] In traditional boat-shaped heating cores, the heating wire is wrapped around a metal rod and directly immersed in the e-liquid, with the e-liquid being directed to the heating wire via a cotton wick. This type of heating core is complex, with the heating wire, cotton wick, and e-liquid guide tube tightly integrated, making cleaning difficult and slow. Therefore, this application provides an atomization structure that allows for rapid e-liquid atomization.

[0030] See Figures 1 to 4 The present application provides an atomization structure, comprising: a shell 100, an oil storage chamber 200 and a heating wire 300. The oil storage chamber 200 is housed in the shell 100, and is used to store tobacco oil. The oil storage chamber 200 is separated from the bottom plate of the shell 100, and the oil storage chamber 200 has a through hole 201 for allowing tobacco oil to flow to the bottom plate of the shell 100. The heating wire 300 is arranged on the bottom plate of the shell 100, and the plane where the heating wire 300 is located is parallel to the plane where the bottom plate of the shell 100 is located. The heating wire 300 is used to heat the tobacco oil on the bottom plate of the shell 100. In some feasible implementations, the height direction of the shell 100 is the Z-axis direction, the length direction of the shell 100 is the X-axis direction, and the width direction of the shell 100 is the Y-axis direction.

[0031] The housing 100 is the skeleton and outer shell of the entire atomization structure. Its main function is to protect and secure internal components, such as the oil storage chamber 200 and the heating wire 300. The housing 100 is preferably made of stainless steel or aluminum alloy to provide sufficient structural strength and durability. Furthermore, the outer surface of the housing 100 can be anodized or sandblasted to enhance its wear resistance and aesthetics. The housing 100 can also be made of lightweight, low-cost engineering plastics, such as polycarbonate.

[0032] The material of the oil storage chamber 200 is a porous structure that does not chemically react with the nicotine, propylene glycol, glycerin, flavoring, and other components in the e-liquid. This not only prevents the production of harmful substances or changes in the flavor of the e-liquid, but also allows the e-liquid stored in the oil storage chamber 200 to flow through the through hole 201 to the bottom plate of the housing 100. For example, the oil storage chamber 200 can be made of ceramic. Figure 3 The bottom surface of the oil storage chamber 200 has a plurality of small elongated through holes 201 to ensure that the volume of the smoke oil flowing to the bottom plate of the housing 100 is small and the speed of being heated and atomized by the heating wire 300 is also fast. Figure 2The housing 100 and the oil storage chamber 200 are separated, and a certain gap exists between the heating wire 300 and the bottom surface of the oil storage chamber 200. When the user is not using the atomization structure, the heating wire 300 is not heated, and a certain air pressure exists in the gap, which prevents the tobacco oil in the oil storage chamber 200 from flowing through the through hole 201 on the bottom surface of the oil storage chamber to the bottom plate of the housing 100. When the user uses the atomization structure, the user inhales the gas, which creates a certain negative pressure in the gap. Under the combined action of the negative pressure and gravity, the tobacco oil flows from the through hole 201 on the bottom surface of the oil storage chamber 200 to the bottom plate of the housing 100, and is heated into smoke gas by the heating wire 300 on the bottom plate of the housing 100. This structure avoids the waste of tobacco oil and ensures that the tobacco oil heated by the heating wire 300 when the user uses the atomization structure is fresh tobacco oil, thereby improving the user experience.

[0033] The heating wire 300 is used to heat the e-liquid on the bottom plate of the housing 100, atomizing the e-liquid to produce smoke. The heating wire 300 is preferably made of an iron-chromium-aluminum alloy or a nickel-chromium alloy. The iron-chromium-aluminum alloy heating wire 300 exhibits excellent oxidation resistance, high strength at high temperatures, and high resistivity. The nickel-chromium alloy heating wire 300 exhibits a fast response, rapid atomization of the e-liquid, and stable heat generation.

[0034] The plane where the heating wire 300 lies is the plane where any cross section of the heating wire 300 lies in the thickness direction, and the plane where the bottom plate of the housing 100 lies is the plane where any cross section of the bottom plate lies in the thickness direction. In one feasible implementation, the plane where the bottom plate of the housing 100 lies and the plane where the heating wire lies are not absolutely parallel. Due to manufacturing process limitations or other reasons, there may be an angle between the plane where the heating wire 300 lies and the plane where the bottom plate of the housing 100 lies, and the angle range is [0°, 10°].

[0035] Compared to the traditional boat-shaped heating core, the heating wire 300 in the present application is tightly attached to the bottom plate of the shell 100. When the heating wire 300 is heated, the heat of the heating wire 300 will be quickly transferred to the bottom plate surface of the entire shell 100, forming a heating plane with a very uniform temperature distribution. The smoke oil in the oil storage chamber 200 flows through the through hole 201 to the bottom plate surface of the shell 100 where the heating wire 300 is located. The smoke oil is heated on the entire plane, the atomization process is more consistent, and the atomization speed is also faster, which can bring a softer, fuller, and less odorous taste experience. In addition, the heating wire 300 is fixed to the bottom plate of the shell 100, and there is no need for metal rods and cotton cores. The overall structure is stronger and simpler. When cleaning the atomization structure, the user can directly replace the bottom plate of the entire shell 100, and it is relatively easy to clean the carbon deposits on the bottom plate surface of the shell 100.

[0036] See Figure 5, in the projection in the height direction of the shell 100, the heating wire 300 at least partially overlaps with the bottom surface of the oil storage chamber 200. The heating wire 300 is located directly below the bottom surface of the oil storage chamber 200. When the smoke oil flows to the bottom plate of the shell 100 through the through hole 201 under the combined action of negative pressure and gravity, it can directly contact the heating wire 300 on the bottom plate of the shell 100. In this process, no additional oil guide device is required, which reduces the resistance of the oil guide path, and the smoke oil can be supplied to the heating area on the bottom plate of the shell 100 more promptly and more adequately. When the heating wire 300 coincides with the bottom surface of the oil storage chamber 200, the smoke oil flowing out of the oil storage chamber 200 can immediately contact the uniform heating plane of the bottom plate of the shell 100, making the entire heating process more uniform and the smoke oil atomization speed faster.

[0037] See Figure 4 and Figure 5 The atomization structure also includes a first connector 301 and a second connector 302, both of which are connected to the bottom plate of the shell 100, and the heating wire 300 is connected between the first connector 301 and the second connector 302. The first connector 301 and the second connector 302 are tightly connected to the surface of the bottom plate of the shell 100, for example, by large-area welding, or by screw connection, or by snap connection. The heating wire 300 is connected between the first connector 301 and the second connector 302, and the terminals of the heating wire 300 only need to contact the first connector 301 and the second connector 302 or be simply welded, and the mechanical stress it is subjected to is shared and absorbed by the first connector 301 and the second connector 302. Even if the heating wire 300 moves slightly due to thermal expansion and contraction, it will not directly pull the fragile solder joints, eliminating faults such as intermittent or non-operation caused by cold soldering or desoldering. In some feasible implementations, the first connector 301, the second connector 302, and the heating wire 300 are an integrated structure. The conductive material is poured into a mold and then the excess portion is removed to form the connected first connector 301, the second connector 302, and the heating wire 300. The first connector 301 and the second connector 302 can serve as electrodes to power the heating wire 300. The first connector 301 and the second connector 302 have a large connection area with the bottom plate of the housing 100. For example, using copper pillars or wide metal sheets as the first connector 301 and the second connector 302 results in a low and stable connection resistance. The heating wire 300 can simply be connected between these two low-resistance electrodes, which can make the resistance performance of the heating wire 300 more consistent and the power output more stable.

[0038] See Figure 4 and Figure 5The atomizer structure also includes multiple heating wires 300, which are arranged in parallel between the first connector 301 and the second connector 302. The multiple heating wires 300 are spaced apart between the first connector 301 and the second connector 302, creating a certain gap and layering between the multiple heating wires 300. When the e-liquid flows from the through-hole 201 of the oil storage chamber 200 to the heating wires 300 on the bottom plate of the housing 100, the e-liquid at different locations is heated simultaneously by different heating wires, ensuring more comprehensive and uniform heating of the e-liquid. In terms of circuitry, the parallel connection of multiple heating wires 300 reduces the total resistance of the parallel circuit while maintaining the same total voltage, thereby increasing the total power. This increased power is distributed to each individual heating wire 300, so each heating wire 300 only needs to bear a portion of the total power, which means that the actual operating temperature and current density of each heating wire 300 are reduced. This lower operating temperature effectively slows the oxidation and wear of the heating wires 300, significantly extending the service life of the entire atomizer structure.

[0039] In some feasible implementations, the first connector 301 and the second connector 302 are parallel. One of the first connector 301 and the second connector 302 can serve as the positive electrode of the circuit in which the heating wire 300 is located, and the other of the first connector 301 and the second connector 302 can serve as the negative electrode of the circuit in which the heating wire 300 is located. The first connector 301 and the second connector 302 are parallel, so that the length of the conductive path from the connection point of the first connector 301 and the second connector 302 to the end of multiple parallel heating wires 300 is basically the same, and the resistance difference is smaller. The current will naturally and evenly flow through each heating wire 300, ensuring that each heating wire 300 can obtain almost the same current and power, avoiding the phenomenon of some heating wires 300 overheating while others are not hot due to uneven current. This makes the taste and output of the smoke produced by the atomization structure very stable, and there will be no sudden changes in temperature. Furthermore, since the first connecting member 301 and the second connecting member 302 are parallel and the distance between them is constant, a very stable and consistent tensioning force is provided for the heating wire 300. All the heating wires 300 are tensioned on a plane at the same height. The heating wires 300 at least cover most of the bottom plate of the shell 100, so that the heating conditions of the e-liquid reaching the bottom plate of the shell 100 are consistent, thereby ensuring a uniform taste.

[0040] In some feasible implementations, the heating wire 300 is wavy. This wavy heating wire 300 significantly increases its length and surface area within a limited space, thereby improving thermal efficiency and achieving more uniform heating. The flat, wavy heating wire 300, positioned on the bottom plate of the housing 100, increases the contact area between the e-liquid and the heating wire 300, resulting in more efficient heat transfer and increased atomization speed.

[0041] See Figures 5 to 7 The atomization structure further includes a plurality of fixing members 400, which surround the heating wire 300 and are all connected to the inner wall of the housing 100. A portion of the fixing members 400 is connected to the first connecting member 301, and another portion of the fixing members 400 is connected to the second connecting member 302. The fixing members 400 can be elastic buckles or brackets, which are fixed to the inner wall of the housing 100 at one end by welding or screws, and connected to the first connecting member 301 and the second connecting member 302 at the other end. Figure 5 and Figure 6 The schematic diagram of the connection between the fixing member 400 and the first connecting member 301 is the same as the schematic diagram of the connection between the fixing member 400 and the second connecting member 302. Figure 1 The fixing part 400 may also be a ceramic bracket, which is injection-molded or formed by a precision mold. The ceramic bracket is designed with slots or holes for passing through and fixing the first connector 301 and the second connector 302, as well as metal inserts for connecting the first connector 301 and the second connector 302; the fixing part 400 may also be an engineering plastic bracket, which is injection-molded using high-temperature resistant engineering plastic. The engineering plastic bracket is designed with slots to fix the first connector 301 and the second connector 302, and is connected to the first connector 301 and the second connector 302 by metal springs or conductive plastics. By surrounding and fixing the heating wire 300 from all sides, a plurality of fixing parts 400 is used to ensure that the heating wire 300 can be tightly attached to the bottom plate of the shell 100 without warping, thereby avoiding dry burning or sudden changes in taste caused by displacement of the heating wire 300.

[0042] In some feasible implementations, the oil storage chamber 200 and the shell 100 are an integrated structure. The oil storage chamber 200 and the shell 100 are not two independent parts assembled together, but are formed at one time through a mold, sharing the same part of the material. The oil storage chamber 200 and the shell 100 can be integrally molded of plastic, and liquid engineering plastic is injected into a mold with a cavity of the oil storage chamber 200. After cooling and opening the mold, a complete shell 100 and the internal oil storage chamber 200 are formed. The oil storage chamber 200 and the shell 100 can also be integrally molded of ceramics. Through ceramic molding techniques such as powder metallurgy or gel injection molding, ceramic powder is mixed with a binder and molded in a mold. Then, it is sintered at high temperature to densify the ceramic particles, and finally a ceramic shell 100 with an oil storage cavity is formed. The integrated design of the oil storage chamber 200 and the shell 100 eliminates the problem of oil leakage caused by loose joints, aging or deformation of parts. It also makes the internal structure more compact, eliminating the need to reserve additional space to accommodate a separate oil cup, allowing the entire atomization structure to be made smaller and thinner.

[0043] In some feasible implementations, the housing 100 has an airway interface for outputting the gas generated by the heated e-liquid to the outside of the housing 100. The airway interface can be located on the outer wall of the housing 100 and connected to the airway outside the housing 100. When the e-liquid is heated, the smoke generated by the heating wire 300 enters the airway outside the housing 100 through the airway interface, allowing the user to inhale the smoke gas generated by the atomized e-liquid.

[0044] The present application also provides an electronic cigarette, comprising an airway and Figure 1 In the atomization structure shown, the air duct is used to transport the gas generated by the atomization structure. One end of the air duct is connected to the air duct interface on the atomization structure shell 100, and the other end of the air duct is connected to the mouthpiece, and the user inhales the smoke gas through the mouthpiece. When the user inhales, the smoke in the oil storage chamber 200 reaches the bottom plate of the shell 100 through the through hole 201 on the bottom surface of the oil storage chamber 200. The heating wire 300 heats the smoke oil that reaches the bottom plate of the shell 100, causing the smoke oil to be atomized to produce gas. External air enters from the opening of the oil storage chamber 200. When the air flows through the heating wire 300, it carries away the smoke gas generated by the heating. The smoke passes through the air duct and finally enters the user's mouth from the mouthpiece. In the atomization structure of the electronic cigarette provided in this application, multiple heating wires 300 are integrated into the plane where the bottom plate of the shell 100 is located, which increases the heating area of ​​the smoke oil, so that the smoke oil that reaches the bottom plate of the shell 100 can be quickly atomized, thereby improving the user experience. Furthermore, the atomization structure of the electronic cigarette provided in the present application does not require the use of a connecting rod and a cotton core, and has a simpler structure, thereby improving the production efficiency of the electronic cigarette and reducing the production cost of the electronic cigarette.
