Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomizing device and an electronic cigarette. Background Technology

[0002] Atomizing devices atomize a matrix into an aerosol using an atomizing component. The aerosol flows out from the mouthpiece and is inhaled by the user. In conventional atomizing devices, after the atomizing matrix is ​​injected, the atomizing component remains immersed in it. Over time, this can lead to a decrease in the atomizing component's oil absorption capacity, affecting not only the taste of the atomized matrix but also increasing the risk of matrix leakage during long-term storage or transportation. Utility Model Content

[0003] The main purpose of this application is to propose an atomizing device and an electronic cigarette to solve the technical problem of atomizing components being immersed in e-liquid for a long time.

[0004] To achieve the above objectives, a first aspect of this application provides an atomizing device, the atomizing device comprising:

[0005] The shell has an oil storage cavity for storing the atomizing matrix, and a nozzle is formed on the upper part of the shell;

[0006] An atomizing component is disposed in an oil storage chamber. The atomizing component includes a support member, an oil guide member, and a heating member arranged sequentially from the outside to the inside. The support member has a liquid inlet hole. The atomizing matrix enters the interior of the atomizing component through the liquid inlet hole and comes into contact with the oil guide member and the heating member.

[0007] A closure element is disposed on the support element, and the closure element is deformable to open or close the liquid inlet.

[0008] In some embodiments, the closure is made of at least two layers of materials with different coefficients of thermal expansion.

[0009] In some embodiments, the closure is a double-layered metal sheet.

[0010] In some embodiments, the closure includes a fixed portion and a deformable portion connected together. The fixed portion is fixedly connected to the support member, and the deformable portion is capable of deforming to open or close the liquid inlet. The deformable portion has an arched portion that arches toward the direction away from the liquid inlet.

[0011] In some embodiments, the deformable portion further includes a contraction portion, wherein the deformable portion narrows on both sides near the fixed portion to form a contraction portion.

[0012] In some embodiments, the ratio of the minimum width of the contraction portion to the maximum width of the arched portion is not greater than 0.7 and not less than 0.3.

[0013] In some embodiments, each layer of the closure is a one-piece molded structure.

[0014] In some embodiments, there are multiple liquid inlet holes, and the number of sealing members is the same as the number of liquid inlet holes. Each sealing member is provided in a one-to-one correspondence with the liquid inlet hole. Each sealing member has a unique deformation temperature. The deformation temperature corresponding to at least one sealing member is a first deformation temperature, and the deformation temperature corresponding to at least one sealing member is a second deformation temperature. The first deformation temperature is higher than the second deformation temperature.

[0015] In some embodiments, the sealing member corresponding to the first deformation temperature is provided with a liquid inlet having a first aperture, and the sealing member corresponding to the second deformation temperature is provided with a liquid inlet having a second aperture, wherein the first aperture is larger than the second aperture.

[0016] A second aspect of this application provides an electronic cigarette, characterized in that it comprises:

[0017] An electronic control device; and an atomizing device according to any one of the first aspects above, wherein the atomizing device is electrically connected to the electronic control device.

[0018] Compared with the prior art, this application provides an atomizing device. By setting the related structural design of the sealing component and its arched and contracted parts, the sealing component can suddenly undergo large deformation, thereby quickly responding to the deformation triggering condition and opening or closing the liquid inlet in time. In addition, this application also sets the sealing component with different deformation temperatures and sets different liquid inlet orifice diameters corresponding to different deformation temperatures, etc., so as to gradually open liquid inlets with different orifice diameters according to actual needs, thereby realizing more reasonable liquid inlet control of the atomizing component.

[0024] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] Nebulizers can be used in various fields, such as medical nebulization, beauty nebulization, and cigarette replacement. They primarily work by heating a nebulizing matrix to generate an aerosol, which can be a liquid matrix containing or without nicotine. A nebulizer typically includes a storage chamber for storing the nebulizing matrix and an atomizing component for heating and atomizing the matrix to generate an aerosol.

[0027] like Figures 1 to 3As shown, this application provides an atomizing device, which includes a housing 1, an atomizing component, and a sealing member 7. The housing 1 has an oil storage chamber 2 inside, used to store the atomizing matrix, and a nozzle is formed on the upper part of the housing. The atomizing component is disposed within the oil storage chamber 2 and is used to introduce the atomizing matrix stored in the oil storage chamber 2 into its interior and heat and atomize it to generate an aerosol. Specifically, the atomizing assembly includes a support member 3, an oil guide member 4, and a heating member 5 arranged sequentially from the outside to the inside. The support member 3 is fixedly connected to the housing 1 and supports the oil guide member 4 disposed inside it. The oil guide member 4 can be a hollow cylindrical oil guide cotton. The heating member 5 is disposed inside the oil guide member 4. The heating member 5 can be a heating wire or a heating mesh, etc., without specific limitations. The support member 3 has a liquid inlet hole 6. The atomizing matrix stored in the oil storage chamber 2 enters the atomizing assembly through the liquid inlet hole 6, and then comes into contact with the oil guide member 4, and then into contact with the heating member 5, and is finally heated by the heating member 5 to generate an aerosol. A sealing member 7 is disposed on the outer surface of the support member 3. Specifically, the sealing member 7 can cover the liquid inlet hole 6 on the support member 3, so that it can open or close the liquid inlet hole 6 by deformation.

[0028] When the atomizing device is not in operation, the sealing member 7 can seal the liquid inlet 6, thereby isolating the interior of the atomizing component from the atomizing matrix stored in the oil storage chamber 2. This design prevents the internal components of the atomizing component (such as the oil guide 4) from being constantly immersed in the atomizing matrix, thus maintaining the oil absorption of the atomizing component and the taste of the atomized matrix. It also reduces the likelihood of atomizing matrix leakage during long-term storage or transportation. When the atomizing device is in operation, conditions can trigger the deformation of the sealing member 7. For example, when the atomizing device is in operation, the heating effect of the heating element 5 causes the inner side of the sealing member 7 to reach a certain temperature and deform. Specifically, the deformation of the sealing member 7 can bend and spring open in the direction away from its corresponding liquid inlet 6, thus automatically opening the liquid inlet 6, releasing the isolation between the interior of the atomizing component and the atomizing matrix stored in the oil storage chamber 2, allowing sufficient atomizing matrix to enter the atomizing component and be atomized when the atomizing device is in operation.

[0029] In some embodiments, the sealing element 7 is made of at least two layers of materials with different coefficients of thermal expansion. This arrangement allows temperature to act as a trigger for deformation of the sealing element 7, thereby automatically opening the liquid inlet 6 when the atomizing device is in operation. For example, the sealing element 7 is made of two layers of materials with different coefficients of thermal expansion, where the inner layer has a higher coefficient of thermal expansion than the outer layer. When the inner layer of the sealing element 7 is heated by the heating element 5, its expansion is greater than that of the outer layer, causing the sealing element 7 to bend and spring open in a direction away from its corresponding liquid inlet 6. Specifically, the sealing element 7 can be a double-layered metal sheet.

[0030] See Figure 3To enable the sealing member 7 to respond quickly and accurately to the deformation temperature, and to directly and rapidly generate a large deformation upon reaching the deformation temperature on its inner side instead of undergoing slow deformation, in some embodiments, the sealing member 7 includes a connected fixing part 71 and a deformation part 72. The fixing part 71 is fixedly connected to the support member 72, and the deformation part 72 can deform to open or close the liquid inlet 6. Specifically, the deformation part 72 has an arched part 722 that arches outward from the direction opposite to the liquid inlet. Due to the arched part 722, when the inner temperature of the sealing member 7 reaches the deformation temperature, unlike the slow warping deformation that occurs with ordinary flat sheets, the arched part 722 instantly and directly generates a large outward deformation, thereby quickly opening the liquid inlet 6 to achieve timely liquid entry.

[0031] Furthermore, the deformable portion 72 may also have a contraction portion 721, wherein the width of the deformable portion 72 near the fixed portion 71 narrows to form the contraction portion 721. Understandably, by providing the contraction portion 721, when the inner temperature of the closure 7 reaches the deformation temperature, the contraction portion 721 makes it easier for the arched portion 722 to fold outwards and tilt in a direction away from the liquid inlet 6. In some embodiments, the minimum width of the contraction portion is set to a ratio of no more than 0.7 and no less than 0.3 to the maximum width of the arched portion, thereby providing a better deformation effect for the closure 7.

[0032] At the same time, each layer of the closure 7 can be set as an integral molding structure, so that the closure 7 is not prone to fatigue fracture after multiple deformations.

[0033] In some embodiments, in order to enable the atomizing component to achieve more reasonable liquid inlet control, there are multiple liquid inlet holes 6, and the number of sealing members 7 is the same as the number of liquid inlet holes 6. The sealing members 7 are arranged in a one-to-one correspondence with the liquid inlet holes 6. Each sealing member 7 has a unique deformation temperature. The deformation temperature corresponding to at least one sealing member 7 is the first deformation temperature, and the deformation temperature corresponding to at least one sealing member 7 is the second deformation temperature. The first deformation temperature is higher than the second deformation temperature.

[0034] Specifically, when the inner temperature of the seal 7 reaches its corresponding deformation temperature, the seal 7 will deform. Therefore, by setting a seal-related structural design with different deformation temperatures, this application can gradually open the liquid inlet according to actual needs, thereby achieving more reasonable liquid inlet control of the atomizing component. In actual use, the amount of atomizing matrix required by the user to replenish varies significantly depending on the usage scenario. For example, when a user is bored, they may only take one puff, while when a user has a high demand for inhalation, they may take large, continuous puffs. The amount of atomizing matrix required for these two scenarios differs significantly. To address this, the above-mentioned design allows the second deformation temperature to be reached when the user takes the first or first few puffs, thus quickly opening the liquid inlet 6 to replenish the atomizing matrix. As the user continues to inhale, the temperature continues to rise to reach the first deformation temperature, thereby opening more liquid inlets 6 to replenish sufficient atomizing matrix into the atomizing component.

[0035] Furthermore, for the atomizing device of this application, the sealing member 7 corresponding to the first deformation temperature can be configured with a liquid inlet 6 having a first aperture, and the sealing member 7 corresponding to the second deformation temperature can be configured with a liquid inlet 6 having a second aperture, wherein the first aperture is larger than the second aperture. It is easily understood that the above configuration allows the second deformation temperature to be reached when the user inhales for the first few puffs, thereby quickly opening the smaller liquid inlet 6 to replenish an appropriate amount of atomizing matrix. When the user continues to inhale, the temperature continues to rise to reach the first deformation temperature, subsequently opening a larger liquid inlet 6 to quickly replenish sufficient atomizing matrix into the atomizing component, thereby achieving more reasonable liquid inlet control of the atomizing component.

[0036] This application also proposes an electronic cigarette, which includes an electronic control device and an atomizing device, wherein the atomizing device is electrically connected to the electronic control device. The specific structure of the atomizing device is as described in the above embodiments. Since this atomizing device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.
