[0024] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific implementation mode of the present application is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] In the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] Atomizers can be used in different fields, such as medical atomization, cosmetic atomization, and cigarette replacement, etc. They mainly generate aerosols by heating atomization substrates, which can be liquid substrates containing nicotine or not. Atomizers generally include a liquid storage chamber and an atomization component, wherein the liquid storage chamber is used to store the atomization substrate, and the atomization component is used to heat and atomize the atomization substrate to generate aerosols.

[0027] like Figures 1 to 3As shown, an atomizing device is provided in the present application, and the atomizing device includes a housing 1, an atomizing assembly and a closure 7. Among them, an oil storage chamber 2 is formed inside the housing 1, and the oil storage chamber 2 is used to store the atomizing matrix; the atomizing assembly is arranged in the oil storage chamber 2, and is used to introduce the atomizing matrix stored in the oil storage chamber 2 into the interior thereof 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 arranged inside it, the oil guide member 4 can be a hollow cylindrical oil guide cotton inside, and the oil guide member 4 is provided with a heating member 5 inside, and the heating member 5 can be a heating wire or a heating net, etc., without specific restrictions, and a liquid inlet hole 6 is opened on the support member 3, and the atomizing matrix stored in the oil storage chamber 2 enters the interior of the atomizing assembly through the liquid inlet hole 6, and then contacts with the oil guide member 4, and contacts with the heating member 5 through the oil guide member 4, and finally is heated by the heating member 5 to be atomized to generate an aerosol. The closing member 7 is disposed on the outer surface of the supporting member 3 . Specifically, the closing member 7 can cover the liquid inlet hole 6 opened on the supporting member 3 , so that the liquid inlet hole 6 can be opened or closed by deforming.

[0028] When the atomizer is not working, the closure 7 can close the liquid inlet hole 6, thereby isolating the inside of the atomizer assembly from the atomized matrix stored in the oil storage chamber 2. Such a setting can prevent the internal components of the atomizer assembly (such as the oil guide 4, etc.) from being immersed in the atomized matrix, thereby maintaining the oil absorption of the atomizer assembly and the taste of the atomized matrix after atomization, and it is not easy to leak the atomized matrix during long-term storage or transportation. When the atomizer is working, the conditions for the deformation of the closure 7 can be triggered. For example, when the atomizer is working, the heating effect of the heating element 5 causes the inside of the closure 7 to reach a certain temperature and deform. Specifically, the deformation of the closure 7 can be bent and bounced in the direction away from the corresponding liquid inlet hole 6, so that the liquid inlet hole 6 can be automatically opened, and the isolation between the inside of the atomizer assembly and the atomized matrix stored in the oil storage chamber 2 can be released, so that when the atomizer is working, sufficient atomized matrix can enter the atomizer assembly and be atomized.

[0029] In some embodiments, the closure member 7 is made of at least two layers of materials with different thermal expansion coefficients. Such a setting can make the temperature a condition for triggering the deformation of the closure member 7, so as to realize the automatic opening of the liquid inlet hole 6 when the atomizer is working. For example, the closure member 7 is made of two layers of materials with different thermal expansion coefficients, the thermal expansion coefficient of the inner layer material is greater than the thermal expansion coefficient of the outer layer material, and the inner layer of the closure member 7 expands more than the outer layer after being heated by the heating element 5, which will cause the closure member 7 to bend and bounce away from the corresponding liquid inlet hole 6. Specifically, the closure member 7 can be a double-layer metal sheet.

[0030] See also Figure 3In order to enable the closure member 7 to respond quickly and accurately to the deformation temperature, the closure member 7 directly and quickly produces a large deformation instead of slow deformation after the temperature inside the closure member 7 reaches the deformation temperature. In some embodiments, the closure member 7 includes a connected fixing portion 71 and a deformation portion 72, wherein the fixing portion 71 is fixedly connected to the support member 72, and the deformation portion 72 can be deformed to open or close the liquid inlet hole 6. Specifically, the deformation portion 72 has an arched portion 722 that arches in a direction away from the liquid inlet hole. By setting the arched portion 722, when the temperature inside the closure member 7 reaches the deformation temperature, unlike the slow warping deformation that occurs in an ordinary flat sheet, the arched portion 722 will instantly and directly produce a large deformation that turns outward, thereby quickly opening the liquid inlet hole 6 to achieve timely liquid inlet.

[0031] Furthermore, the deformation portion 72 may also have a contraction portion 721, and the width of the deformation portion 72 near one end of the fixing portion 71 is contracted and narrowed to form the contraction portion 721. It can be understood that, through the setting of the contraction portion 721, when the inner temperature of the closure member 7 reaches the deformation temperature, the contraction portion 721 makes it easier for the arched portion 722 to turn outward and warp in a direction away from the liquid inlet hole 6. In some embodiments, the minimum width of the contraction portion is set to a ratio of not more than 0.7 and not less than 0.3 to the maximum width of the arched portion, thereby providing a better deformation effect for the closure member 7.

[0032] At the same time, each layer of the sealing member 7 can also be set as an integrally formed structure, so that the sealing member 7 is not prone to fatigue fracture after multiple deformations.

[0033] In some embodiments, in order to enable the atomization component to achieve more reasonable liquid inlet control, there are multiple liquid inlet holes 6, the number of the closures 7 is consistent with the number of the liquid inlet holes 6, and the closures 7 are arranged one-to-one with the liquid inlet holes 6; each of the closures 7 corresponds to a unique deformation temperature, and the deformation temperature corresponding to at least one closure 7 is a first deformation temperature, and the deformation temperature corresponding to at least one closure 7 is a second deformation temperature, and the first deformation temperature is higher than the second deformation temperature.

[0034] Specifically, when the inner temperature of the closure 7 reaches its corresponding deformation temperature, the closure 7 will be deformed. Therefore, the present application can gradually open the liquid inlet hole according to actual needs by setting the relevant structural design of the closure with different deformation temperatures, thereby realizing a more reasonable liquid inlet control of the atomizer assembly. In actual use, there are obvious differences in the amount of atomized matrix required to be supplemented when the user sucks in different use scenarios. For example, when the user occasionally feels bored, he only sucks a mouthful, and when the user has a higher suction demand, he continues to suck in large mouthfuls. There are obvious differences in the amount of atomized matrix required to be supplemented between the two. In view of this situation, the above-mentioned setting can reach the second deformation temperature when the user sucks the first mouthful or the first few mouthfuls, so as to quickly open the liquid inlet hole 6 to supplement the atomized matrix. When the user continues to suck, the temperature continues to rise to reach the first deformation temperature, and then open more liquid inlet holes 6 to supplement a sufficient amount of atomized matrix inside the atomizer assembly.

[0035] Further, for the atomization device of the present application, the closure member 7 corresponding to the deformation temperature of the first deformation temperature can be set corresponding to the liquid inlet hole 6 with a first aperture, and the closure member 7 corresponding to the deformation temperature of the second deformation temperature can be set corresponding to the liquid inlet hole 6 with a second aperture, and the first aperture is larger than the second aperture. It is easy to understand that the above setting can reach the second deformation temperature when the user takes the first or first few puffs, thereby quickly opening the smaller liquid inlet hole 6 to replenish an appropriate amount of atomized matrix. When the user continues to inhale, the temperature continues to rise to reach the first deformation temperature, and then opens a larger liquid inlet hole 6 to quickly replenish a sufficient amount of atomized matrix into the atomization component, thereby achieving a more reasonable liquid inlet control of the atomization component.
