Description

Technical Field

[0001] This invention relates to the field of electronic atomizing devices, and in particular to an atomizing component. Furthermore, this invention also relates to an electronic atomizing device comprising the aforementioned atomizing component. Background Technology

[0002] Currently, the atomizing components of electronic atomizing devices on the market are basically divided into two types: flexible atomizing cores formed by combining oil-wicking cotton and heating elements, and hard atomizing cores formed by sintering heating elements and ceramic bodies. Each of the two atomization methods has its own characteristics.

[0003] However, in flexible atomizing core structures composed of wicking cotton and heating elements, whether the spiral heating wire is wound around the wicking cotton, wrapped around the wicking cotton, or the flat heating element is directly attached to the wicking cotton in a separate manner, the wicking cotton, being relatively soft, experiences compression when it is tightly bonded to the heating element. This compression can easily deform the heating element, resulting in poor stability of the bond between the wicking cotton and the heating element, potentially leading to two problems. First, if the wicking cotton and heating element are tightly bonded, the heating wire may be deformed due to compression, causing damage or short circuits; the thickness of the wicking cotton may also become uneven after compression, resulting in inconsistent e-liquid storage rates and a poor flavor. Second, if the wicking cotton and heating element are loosely bonded, they may not adhere completely, leading to areas where e-liquid is not atomized and causing dry burning.

[0004] In summary, how to effectively solve the problems of structural stability and deformation resistance of atomizing components is an urgent issue that needs to be addressed by those skilled in the art. Summary of the Invention

Detailed Implementation

[0040] The core of this invention is to provide an atomizing component with strong resistance to deformation and good stability of the heating wire, thereby improving atomization efficiency; another core aspect of this invention is to provide an electronic atomizing device including the above-mentioned atomizing component, which has the same beneficial effects as the atomizing component.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of the heating element provided in one embodiment of the present invention; Figure 2 This is a front structural diagram of the atomizing component provided in one embodiment of the present invention; Figure 3 for Figure 2 A schematic diagram of the rear structure; Figure 4 and Figure 5 This is a front structural schematic diagram of the atomizing component provided in some other embodiments of the present invention.

[0043] In one specific embodiment, the atomizing component provided by the present invention includes:

[0044] A flat heating element 1 and a flexible porous body 2 integrally injection molded with the heating element 1;

[0045] The flexible porous body 2 includes a main liquid region 21 and a covering region 22 connected to a portion of the side of the main liquid region 21;

[0046] The heating element 1 includes a heating part 11 and a connecting part 12 connected to the side of the heating part 11. The heating part 11 is attached to and exposed on one side of the main liquid area 21, and the connecting part 12 is at least partially embedded in the covering area 22.

[0047] In the above structure, the atomizing component includes a heating element 1 and a flexible porous body 2. The heating element 1 is flat and is a metal sheet made of metal material by stamping or etching.

[0048] The heating element 1 includes a heating part 11 and a connecting part 12. The heating part 11 is the main heating area and is the main heating element 11. The connecting part 12 is connected to the side of the heating part 11. The connecting part 12 is used to assist the heating part 11 in supporting and fixing it. Of course, the connecting part 12 can also be used to connect to an external power source.

[0049] The flexible porous body 2 includes a main liquid region 21 and a coating region 22. The coating region 22 is connected to a portion of the side of the main liquid region 21, and the main liquid region 21 and the coating region 22 are a single unit. Optionally, the flexible porous body 2 is porous cotton, which has good oil storage properties and low cost.

[0050] Furthermore, the flexible porous body 2 and the heating element 1 are integrally injection molded, with the heating part 11 attached to and exposed on one side of the main liquid area 21, and the connecting part 12 at least partially embedded in the covering area 22, so that the flexible porous body 2 and the heating element 1 are embedded and tightly attached to form a whole, with a stable structure. The heating element 1 and the flexible porous body 2 are not prone to displacement, which improves the deformation resistance of the heating element 1. The heating element 1 has good stability and improves the atomization efficiency.

[0051] Based on the above specific implementation, the covering area 22 is arranged continuously or intermittently around the outer periphery of the main liquid area 21, and the covering area 22 encloses the atomizing channel 3 on the side of the main liquid area 21 facing the heating part 11.

[0052] In practical applications, the coating area 22 is arranged around the outer periphery of the main liquid area 21. The coating area 22 encloses the atomization channel 3 on the side of the main liquid area 21 facing the heating part 11, and the heating part 11 is exposed and not covered in the coating area 22.

[0053] The coating region 22 can be continuously or intermittently surrounding the outer periphery of the dominant liquid region 21. For example, as... Figure 5 As shown, when the cross-section of the main liquid region 21 is rectangular, the main liquid region 21 is surrounded by a covering region 22. It is understood that in some embodiments, the covering region 22 may be discontinuous on each side of the main liquid region 21, such as... Figure 2 and Figure 4 As shown.

[0054] The covering area 22 also has an oil storage function. When the e-liquid in the central main liquid area 21 is consumed, the covering area 22 replenishes the e-liquid in the main liquid area 21. The replenishment efficiency is better than that of non-single-sided covering. The heating element 1 has flexible porous bodies 2 on both sides, which facilitates fixing and sealing with other components. It has better sealing performance than the single-sided flexible porous body 2 covering the heating wire. The double-sided flexible porous body 2 can also reduce heat dissipation outward, which is beneficial to improving atomization efficiency.

[0055] Based on the above specific embodiments, the atomizing channel 3 extends through to the opposite two sides of the flexible porous body 2.

[0056] In practical applications, the connecting part 12 can be completely wrapped, leaving only one side of the heating part 11 covered by the flexible porous body 2. At this time, the bonding force between the heating wire and the flexible porous body 2 is well fixed and has strong stability.

[0057] To make the delivery of aerosols and nicotine more effective, the connecting part 12 may not be fully wrapped with cotton, leaving the atomization channel 3 open. The atomization channel 3 can ensure that TPM, aerosols and nicotine can pass through smoothly.

[0058] Specifically, the covering area 22 forms a through-atomization channel 3 on opposite sides, meaning the covering area 22 connects to opposite sides of the main liquid area 21, while no covering area 22 is provided on the other pair of opposite sides of the main liquid area 21. In this case, the covering area 22 can still replenish the e-liquid in the main liquid area 21, with a replenishment efficiency better than single-sided covering. The heating element 1 has flexible porous bodies 2 on both sides, facilitating fixation and sealing with other components, providing better sealing than single-sided flexible porous bodies 2 covering the heating wire. The double-sided flexible porous bodies 2 also reduce heat dissipation outwards, improving atomization efficiency. Simultaneously, the flow resistance of the aerosol formed by the atomization of the heating element 1 during atomization helps reduce draw resistance.

[0059] In the process of implementing this application, the inventors discovered that, compared with the related technology, when the flat heating element 1 and the flexible porous body 2 are attached in a separable (split-type) manner, a rigid support sheet needs to be added to the side of the heating element 1 facing away from the flexible porous body 2 to support the heating element 1 and the flexible porous body 2. In this case, the flexible porous body 2, the heating element 1 and the support sheet are stacked in sequence. The support member reduces the deformation of the flexible porous body 2 and the heating element 1 when they are assembled into the atomizer, thereby solving the problem that the flexible porous body 2 and the heating element 1 cannot be fully attached due to deformation.

[0060] When applying the technical solution provided in the embodiments of the present invention, since the heating element 1 and the flexible porous body are injection molded as one piece with reliable bonding and good stability, the heating element 1 is not easily deformed, thus eliminating the need for rigid support components. The rubber-coated steel sheet is eliminated, and the device is fixed by the adhesion of cotton on both sides, resulting in a good bonding effect. Simultaneously, the non-bonded sides also form the airway sides, improving oil storage and supply efficiency, reducing heat leakage, and reducing noise. This allows the aerosol generated by atomization to enter the airway without loss, improving atomization efficiency and providing a stronger user experience. The flexible porous body 2 is more tightly bonded to the heating element 1, with consistent thickness and oil storage rate throughout, resulting in better flavor. The heating element 1 is embedded in the flexible porous body 2, maintaining e-liquid atomization in the heating area, preventing dry burning and scorching, and extending the service life of the heating element 1. This reduces the assembly cost of the heating element 1 and the flexible porous body 2, saving time. Based on the above specific embodiments, as... Figure 6 As shown, Figure 6 A schematic diagram shows the structure where the coating area 22 and the main liquid area 21, facing away from the heating element 1, are flush with the coating area 22. The side of the main liquid area 21 facing away from the heating element 1, flush with the coating area 22, is the liquid absorption surface, used for fluid communication with the lower oil channel of the atomizer's liquid storage chamber. During injection molding and installation, the surface mating with this surface is a single plane, facilitating processing and assembly; the relatively thick connection between the main liquid area 21 and the coating area 22 increases strength and improves the deformation resistance of the heating element 1.

[0061] In some specific embodiments, based on any of the above embodiments, in a first direction parallel to the heating element 1, the connecting portion 12 includes electrode portions 121 connected to both sides of the heating element 11.

[0062] In a direction parallel to the heating element 1 and the same as or different from the first direction, a covering area 22 is provided on each side of the main liquid region 21, and each electrode part 121 is at least partially located in the covering area 22.

[0063] In practical applications, the connecting part 12 includes an electrode part 121, which is connected to both sides of the heating part 11. The electrode part 121 is parallel to the heating part 11, and optionally, both sides are flush and have the same thickness.

[0064] When the main liquid region 21 has a covering region 22 on each side, the covering region 22 is parallel to the heating element 1. The areas of the electrode part 121 and the covering region 22 can overlap or partially overlap. That is, when the electrode part 121 is in a first direction parallel to the heating element 1 and the covering region 22 is in a direction parallel to the heating element 1 and the same or different from the first direction, if they do not overlap, each electrode part 121 is at least partially located within the covering region 22; when they overlap, the electrode part 121 is covered within the covering region 22. The double-sided flexible porous body 2 provides support and protection for the electrode part 121, improves the deformation resistance of the electrode part 121, and facilitates fixing with other components.

[0065] Based on the above specific embodiments, in a second direction parallel to the heating element 1 and intersecting the first direction, electrode portions 121 are respectively provided on both sides of the heating element 11, and the two ends of the electrode portions 121 extend into the covering area 22 along the first direction. At this time, the electrode portions 121 and the covering area 22 are perpendicular, and the end portion of each electrode portion 121 is located within the covering area 22. The end portion of the electrode portion 121 is a vulnerable part, and the covering area 22 supports and protects the end portion of the electrode portion 121, improving the deformation resistance of the end of the electrode portion 121, reducing damage to the electrode portion 121, and facilitating fixation with other components. The first direction and the second direction can be perpendicular to each other. The first direction can be the length direction of the flexible porous body 2, and the second direction can be the width direction of the flexible porous body 2, or the first direction can be the width direction of the flexible porous body 2, and the second direction can be the length direction of the flexible porous body 2. This application does not impose specific limitations on this. It should be noted that in some other embodiments, the first direction and the second direction can be set at an angle of less than 90°.

[0066] Based on the above specific embodiments, in the first direction, the ends of the two electrode portions 121 that are far apart from each other are respectively connected to welding portions 122. The welding portions 122 are located outside the covering area 22 and are connected to external components. The welding portions 122 are exposed outside the covering area 22, which facilitates welding connection with external components.

[0067] Based on the above specific embodiments, in the first direction, the connecting part 12 further includes a support part 13 connected to both sides of the heating part 11, with one end of the support part 13 away from the heating part 11 located in the corresponding covering area 22 on both sides.

[0068] In practical applications, the connecting part 12 also includes a support part 13. The support part 13 is connected to both sides of the heating part 11 in the first direction. The end of the support part 13 away from the heating part 11 is located in the corresponding covering area 22 on both sides. The covering area 22 covers and protects the end of the support part 13 away from the heating part 11, thereby improving the deformation resistance of the support part 13.

[0069] In some specific embodiments, based on any of the above embodiments, the connecting part 12 is provided with a cotton-pulling hole 14. The flexible porous body 2 of the covering area 22 is connected to the part on the other side of the connecting part 12 through the cotton-pulling hole 14. The body is covered with cotton on both sides and can be fixed by the cotton-pulling hole 14 on the heating wire in the middle. This allows the cotton on the top and bottom to pass through the empty cotton-pulling hole 14 to form a whole, thereby increasing the bonding force between the cotton and the heating wire. This makes the bonding force strong and less likely to separate and curl up, causing the core to become sticky. This improves the reliability of the combination between the flexible porous body 2 and the heating element 1 and the liquid transmission capacity on both sides of the covering area 22, thereby giving the user a better experience.

[0070] Optionally, there can be one or more cotton-pulling holes 14, which can be on the wider electrode portions 121 at both ends or on the thinner support portions 13. The diameter of the cotton-pulling holes 14 is any value from 0.01 to 0.5 mm, including the end values. Preferably, the diameter of the cotton-pulling holes 14 is 0.02 to 0.05 mm, for example, 0.04 mm. The cotton-pulling holes 14 are evenly distributed along the connecting portion 12, which uniformly improves the reliability of the connection between the flexible porous body 2 and the heating element 1.

[0071] In some specific embodiments, based on any of the above embodiments, the density of the coating region 22 is higher than the density of the dominant liquid region 21.

[0072] In practical applications, the density of the flexible porous body 2 in the covering area 22 and the main liquid area 21 can be the same or different, and can be set differently. For example, the main liquid area 21 in the middle can be low in density and fluffy, which is conducive to oil conduction and does not easily cause the core to stick; the density of the surrounding covering area 22 is greater than that of the main liquid area 21 for sealing, and the liquid-locking ability of the edge of the flexible porous body 2 prevents the flexible porous body 2 from leaking from the edge area.

[0073] Based on the above specific embodiments, the material of the main liquid area 21 is linen nonwoven fabric, and the material of the covering area 22 is viscose nonwoven fabric.

[0074] In practical applications, the materials selected for the flexible porous body 2 in the covering area 22 and the main liquid area 21 can also be different. The main liquid area 21 in the middle is made of high-temperature resistant material, such as flax nonwoven fabric, which is not easy to clog the core; the surrounding covering area 22 is made of high oil storage capacity material, such as viscose nonwoven fabric, which is conducive to oil storage and timely replenishment.

[0075] In some specific embodiments, such as Figure 7 , Figure 7 A cross-sectional structural diagram is shown of a flexible porous body 2 having a first part 201 and a second part 202 respectively on opposite sides of the heating element 1. Based on any of the above embodiments, the heating element 1 has opposing first and second surfaces;

[0076] The flexible porous body 2 includes a first part 201 injection-molded on a first surface and a second part 202 injection-molded on a second surface. In the projection of the first part 201 in the direction perpendicular to the heating element 1, the area of ​​the first part 201 is larger than the area of ​​the second part 202, and the overlapping area of ​​the first part 201 and the second part 202 forms a covering area 22, and the non-overlapping area of ​​the first part 201 and the second part 202 forms a dominant liquid area 21.

[0077] In practical applications, the thicknesses of the covering area 22 and the main liquid area 21 are different. The thickness of the covering area 22 is the sum of the thicknesses of the first part 201 and the second part 202, while the thickness of the main liquid area 21 is the thickness of the first part 201. The covering area 22 protrudes from the main liquid area 21 in the second part 202 of the heating element 1 by the height of the second part 202. The thickness of the heating wire is generally 0.06-0.15mm, and the protrusion height should be at least greater than the thickness of the heating wire to completely cover it, preferably within the range of 0.5-1.5mm.

[0078] Based on the above specific embodiments, the first part 201 is made of cotton fiber; the second part 202 is made of polyester fiber.

[0079] In practical applications, the first part 201 and the second part 202 can be made of different materials. The first part 201 is made of oil-wicking cotton, which is mainly made of cotton fiber. It wicks oil quickly and has a higher temperature resistance than polyester. The second part 202 is made of ordinary oil-storing cotton, which is mainly made of polyester fiber and has a large oil storage capacity.

[0080] In some specific embodiments, such as Figure 8 , Figure 8A cross-sectional structural diagram is shown for both the first part 201 and the second part 202, which include an inner cotton layer 2001 and an outer cotton layer 2002. Based on the above specific embodiments, both the first part 201 and the second part 202 include an integral cotton layer with at least two layers of cotton. The cotton layer on the side of the first part 201 and the second part 202 closest to the heating element 1 is the inner cotton layer 2001, and the side of the inner cotton layer 2001 away from the heating element 1 is the outer cotton layer 2002. The high temperature resistance of the inner cotton layer 2001 is higher than that of the outer cotton layer 2002. For example, the inner cotton layer 2001 is made of cotton fiber material, and the outer layer is made of polyester fiber, which can further improve the high temperature resistance of the side of the first part 201 and the second part 202 in contact with the heating element 1 and prevent the cotton quilt from burning.

[0081] Based on the above specific embodiments, the porosity of the second part 202 is less than that of the first part 201.

[0082] In practical applications, when the cotton padding is located on the upper and lower sides of the heating wire, it can be a flexible porous body 2 of the same material but with different porosities. The second part 202 has a small porosity and is relatively densely compressed, which can improve the efficiency of oil storage and supply, reduce heat leakage, and reduce noise. The first part 201 has a large porosity and is relatively loosely compressed, which can quickly guide oil through the air passage and ensure the replenishment of e-liquid when the heating wire is working.
