Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to an atomizing component and an atomizer. Background Technology

[0002] Existing atomizers include atomizing components for atomizing the aerosol-generating matrix. These components typically consist of an atomizing tube, a liquid-guiding cotton, and an atomizing core (heating element). The atomizing tube has a liquid inlet, the liquid-guiding cotton is installed inside the tube, and the atomizing core is fixed to the liquid-guiding cotton. The liquid matrix is ​​immersed in the liquid-guiding cotton through the inlet and then transported to the atomizing core via the cotton. However, existing atomizing components suffer from uneven liquid inlet and delivery, and slow delivery speed, failing to provide the atomizing core with sufficient matrix when the heating element is operating continuously. Utility Model Content

[0003] The main purpose of this invention is to provide an atomizing component and atomizer that can solve the material leakage problem existing in the atomizer in the prior art.

[0004] To achieve the above objectives, this application provides an atomizing component, comprising:

[0005] The outer tube has at least one first liquid inlet hole;

[0006] An inner tube is disposed inside the outer tube. The inner tube is provided with a second liquid inlet and a third liquid inlet. The cross-sectional area of ​​the second liquid inlet is greater than or equal to the cross-sectional area of ​​the first liquid inlet.

[0007] A first liquid guiding medium is installed between the outer tube and the inner tube;

[0008] A second liquid guiding medium is installed inside the inner tube. A gas channel is formed on the second liquid guiding medium. The second liquid guiding medium extends at least partially through the third liquid inlet hole to the outside of the inner tube.

[0009] A heating element is installed in the gas channel. The heating element includes an atomizing part and at least two electrodes. The atomizing part has an arc-shaped cross-section. The opening of the atomizing part is away from the second liquid inlet hole. The two electrodes are located at both ends or on the inner wall of the atomizing part, respectively.

[0010] A porous first liquid-conducting medium rapidly absorbs liquid from the outside through a first liquid inlet. A porous second liquid-conducting medium comes into contact with the liquid from different directions through a second and a third liquid inlet, and slowly absorbs the liquid stored in the first liquid-conducting medium through capillary action, and transfers the liquid to the heating element. When the heating element is energized, it releases heat energy to atomize the liquid and form an aerosol. The aerosol is consumed through the gas channel when the user inhales.

[0011] In some embodiments, the second inlet is on the same side as the first inlet. It is desirable for liquid to pass rapidly through the second inlet and be absorbed by the second liquid guiding medium.

[0012] In some embodiments, the second liquid inlet and the third liquid inlet are respectively located on opposite sides of the inner tube. The atomizing section near the second liquid inlet allows for rapid liquid wetting, while the third liquid inlet serves as a supplement, directing liquid into a portion of the atomizing section away from the second liquid inlet.

[0013] In some embodiments, the atomizing assembly further includes a sealing tube disposed inside the inner tube. One end of the sealing tube is connected to the inner tube, and the other end of the sealing tube abuts against the second liquid guiding medium and is connected to the gas channel. A limiting groove is formed on the side of the inner tube away from the second liquid inlet, and the sealing tube closes part of the limiting groove to form the third liquid inlet.

[0014] In some embodiments, the cross-sectional area of ​​the third inlet hole is smaller than that of the second inlet hole.

[0015] In some embodiments, both the first and second liquid-conducting media are porous media, and the density of the first liquid-conducting media is less than that of the second liquid-conducting media. It is understood that the lower-density first liquid-conducting media has more pores, enabling it to absorb and release liquid quickly, while the higher-density second liquid-conducting media has fewer pores, resulting in slower liquid absorption and release compared to the first liquid-conducting media.

[0016] In some embodiments, the arc length of the atomizing section is greater than or equal to the diameter of the second liquid inlet.

[0017] On the other hand, this application also provides an atomizer that includes the atomizing components in any of the above embodiments.

[0018] Compared with the prior art, this utility model guides external liquid into the outer tube through the first liquid inlet hole, and uses the first liquid guiding medium with high absorption efficiency to quickly absorb the liquid. The second liquid guiding medium obtains more contact area with the liquid through the second liquid inlet hole, thereby allowing the atomizing part in contact with the liquid to have more contact area. At the same time, the second liquid guiding medium reduces the release rate of the liquid, avoiding the liquid being released too quickly due to the negative pressure generated when the user inhales the atomizer.

[0027] 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.

[0028] In the description of this application, unless otherwise expressly specified and defined, the terms "installation," "connection," "linking," "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 defined. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] On the one hand, this application provides an atomizing component, see [link to relevant documentation]. Figures 1 to 6The atomizing component includes an outer tube 1, an inner tube 3, a first liquid guiding medium 2, a second liquid guiding medium 4 having a gas channel 40, and a heating element 5. The inner tube 3 is installed inside the outer tube 1, the first liquid guiding medium 2 is installed between the outer tube 1 and the inner tube 3, the second liquid guiding medium 4 is installed inside the inner tube 3, and the heating element 5 is installed inside the gas channel 40.

[0030] Specifically, outer tube 1 has a hollow tube structure, see [link / reference]. Figure 3 As shown, the outer tube 1 is provided with at least one first liquid inlet hole 10, which is connected to the inner tube 3. The external liquid located in the atomizing component is stored in the first liquid guiding medium 2 through the first liquid inlet hole 10. It can be understood that the number of first liquid inlets 10 can be 2, 3, 4, or even more. Multiple first liquid inlets 10 are distributed circumferentially on the outer tube 1, and the first liquid guiding medium 2 can absorb liquid from different directions simultaneously, promoting the first liquid guiding medium 2 to quickly reach saturation.

[0031] See Figure 3 As shown, the inner tube 3 is a hollow tube structure, and is disposed inside the outer tube 1. The first liquid guiding medium 2 is sandwiched between the inner tube 3 and the outer tube 1. The inner tube 3 is provided with a second liquid inlet 30 and a third liquid inlet 31 that communicate with the interior of the inner tube 3. The second liquid inlet 30 is positioned opposite to the first liquid inlet 10. In addition, the cross-sectional area of ​​the second liquid inlet 30 is greater than or equal to the cross-sectional area of ​​the first liquid inlet 10, so that most of the liquid enters the inner tube 3 through the second liquid inlet 30 and is absorbed by the second liquid guiding medium 4.

[0032] The third liquid inlet 31 is located on the opposite side of the second liquid inlet 30. (Combined) Figure 4 As shown, in some embodiments, the third liquid inlet 31 can be a groove with a narrow opening, through which a portion of the second liquid guiding medium 4 is held.

[0033] The first liquid-conducting medium 2 is fixed between the inner tube 3 and the outer tube 1 by an interference fit, and absorbs external liquid through the first liquid inlet 10. Both the first liquid-conducting medium 2 and the second liquid-conducting medium 4 are porous structures, with pores forming liquid flow paths that allow liquid to remain and flow. Common porous structures include ceramics, cotton, foam, or fibers, such as loose fibers; or combinations thereof. The density of the first liquid-conducting medium 2 may be the same as or different from the density of the second liquid-conducting medium 4. In some embodiments, to quickly absorb liquid from outside the atomizing assembly, the liquid absorption rate of the first liquid-conducting medium 2 is greater than that of the second liquid-conducting medium 4.

[0034] refer to Figure 3As shown, the first liquid guiding medium 2 has a shape adapted to the internal channel of the outer tube 1, such as a column. The first liquid guiding medium 2 is provided with a mounting hole, and the inner tube 3 is assembled into the mounting hole. It can be understood that the distance between the inner tube 3 and the outer tube 1 is smaller than the diameter of the first liquid guiding medium 2, so that the first liquid guiding medium 2 is interference-fitted between the inner tube 3 and the outer tube 1.

[0035] The second liquid guiding medium 4 is installed inside the inner tube 3. In some examples, the second liquid guiding medium 4 is interference-fitted into the inner tube 3. See also Figure 4 As shown, the second liquid-conducting medium 4 is provided with a gas channel 40, and the heating element 5 is installed in the gas channel 40. The second liquid-conducting medium 4 extends at least partially through the third liquid inlet 31 to the outside of the inner tube 3, and the extended portion is engaged in the third liquid inlet 31 and abuts against the first liquid-conducting medium 2. Furthermore, the extended portion absorbs liquid from the first liquid-conducting medium 2 and diffuses into other passages of the second liquid-conducting medium 4 through capillary action.

[0036] The density of the first liquid-conducting medium 2 is less than that of the second liquid-conducting medium 4. Understandably, the first liquid-conducting medium 2, with its lower density, has more pores and can absorb and release liquid quickly, while the second liquid-conducting medium 4, with its higher density, has fewer pores and absorbs and releases liquid more slowly than the first liquid-conducting medium 2.

[0037] See Figure 2 As shown, the heating element 5 is installed within the gas channel 40, and is in close contact with the second liquid-conducting medium 4 to consume the liquid on the second liquid-conducting medium 4 to generate an aerosol. The heating element 5 includes an atomizing part and at least two electrodes 51. The atomizing part has electrically connected positive and negative terminals, and the two electrodes 51 have positive and negative terminals. Figure 5 As shown, the atomizing section is generally C-shaped with a superior arc-shaped cross-section. The arc length of the atomizing section is greater than or equal to the diameter of the second liquid inlet 30. The opening direction of the atomizing section is away from the second liquid inlet 30, and the superior arc surface of the atomizing section contacts the second liquid guiding medium 4 in the direction close to the second liquid guiding hole. In some embodiments, the electrode 51 is fixed on the side of the atomizing section away from the second liquid guiding medium 4.

[0038] The porous first liquid-conducting medium 2 rapidly absorbs liquid from the outside through the first liquid inlet 10. The porous second liquid-conducting medium 4 absorbs the liquid retained on the first liquid-conducting medium 2 from different directions through the second liquid inlet 30 and the third liquid inlet 31. The heating element 5 releases heat energy to atomize the liquid and form an aerosol when it is energized. The aerosol is consumed through the gas channel 40 when the user inhales.

[0039] The atomizing assembly also includes a hollow, sealed tube 6, which is disposed within the inner tube 3. For example... Figure 6As shown, one end of the closed tube 6 is connected to the inner tube 3, and the other end of the closed tube 6 abuts against the second liquid guiding medium 4 and is connected to the gas channel 40. The closed tube 6 closes part of the groove on the inner tube 3 to form a third liquid inlet 31. The cross-sectional area of ​​the third liquid inlet 31 is smaller than that of the second liquid inlet 30, reducing the amount of liquid passing through the third liquid inlet 31 and preventing excessive liquid from flowing into the non-atomizing area of ​​the atomizing section.

[0040] On the other hand, this application also provides an atomizer that includes the atomizing components in any of the above embodiments.

[0041] The atomizing component guides external liquid into the outer tube 1 through the first liquid inlet 10. The liquid is quickly absorbed by the first liquid guiding medium 2, which has a high liquid absorption efficiency. The second liquid guiding medium 4 obtains a larger contact area with the liquid through the second liquid inlet 30, so that the atomizing part in contact with the second liquid guiding medium 4 can be in almost complete contact with the liquid. At the same time, the second liquid guiding medium 4 reduces the release rate of the liquid, avoiding the liquid from being released too quickly due to the negative pressure generated when the user inhales the atomizer.

[0042] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
