[0002] An atomizing device is used to atomize a liquid medium into an aerosol. It mainly includes an oil cup for storing the atomizing liquid and an atomizing component assembled within the oil cup. The atomizing component typically includes an oil guide and a heating wire mounted on one side of the oil guide. The oil guide directs the atomizing liquid from the oil cup to the heating wire, where it is atomized into an aerosol. However, in related technologies, the structure of the oil guide is not conducive to the conduction of the atomizing liquid, resulting in uneven distribution of the atomizing liquid during use. This can easily cause the heating wire to burn out, leading to coil clogging and affecting the quality of the atomizing device. Summary of the Invention

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] This embodiment provides an electronic atomizing device (not shown), including a battery rod and an atomizer, which are plugged into each other.

[0041] Among them, combined Figure 1-3 The atomizer includes an oil cup 1 and an atomizing assembly 2. The atomizing assembly 2 includes a bottom assembly 21, a top assembly 22 installed on the top of the bottom assembly 21, and an atomizing coil 23. The top assembly 22 is installed inside the oil cup 1 and is sealed to the inner wall of the oil cup 1. The bottom assembly 21 includes a base 211 installed on one end of the oil cup 1, and the atomizing coil 23 is clamped and positioned between the base 211 and the top assembly 22. The top assembly 22 is provided with a liquid inlet channel 2211 for supplying the atomized liquid in the oil cup 1 to the atomizing coil 23. The atomizing coil 23 includes a stacked planar heating wire 231 and an oil guide body 232, which is located between the top assembly 22 and the planar heating wire 231 and is connected to the liquid inlet channel 2211.

[0042] Further integration Figure 3-6 The oil guide body 232 is fitted and assembled with the planar heating wire 231. The oil guide body 232 includes a first side surface S1 and a second side surface S2 that are arranged opposite to each other and parallel to each other. The material texture of the oil guide body 232 extends along the longitudinal direction. The material texture is formed by the material forming the oil guide body 232 being arranged in the longitudinal direction. For example, when using fibrous material, the fibrous material is arranged along the longitudinal direction, and the fibrous material and the gaps between the fibrous materials together form the material texture.

[0043] When the wicking body 232 is assembled into the atomizer, it can be fitted to the planar heating wire 231. During the use of the atomizer, since the extension direction of the material of the wicking body 232 is in the longitudinal direction, the atomized liquid can be conducted along the extension direction of the material, which improves the conduction efficiency of the atomized liquid. This facilitates the conduction of the atomized liquid to the heating concentration area of ​​the planar heating wire 231, ensuring sufficient oil supply, preventing clogging, and improving the vaping experience.

[0044] Specifically, in this embodiment, the base 211 has an air inlet and includes a support portion. The middle part of the support portion has an opening communicating with the air inlet. The bottom assembly 21 also includes an electrode (not shown) passing through the support portion. The planar heating wire 231 includes a heating portion and a conductive portion extending laterally from both ends of the heating portion. The conductive portion is supported on the top surface of the support portion and electrically connected to the electrode. The heating portion is suspended at the opening of the support portion. The oil guide body 232 is fitted and assembled on the top surface of the planar heating wire 231. The top assembly 22 includes a bracket 221 sleeved on the base 211 and a silicone sealant 222 sealingly connected between the bracket 221 and the oil cup 1. The liquid inlet channel 2211 is disposed between the bracket 221 and the silicone sealant. The bracket 221 and the base 211 together clamp and fix the oil guide body 232. Furthermore, the oil guide body 232 covers the liquid inlet channel 2211 of the bracket 221. An atomization chamber is formed between the bracket 221 and the base 211. The oil cup 1 has an outlet channel communicating with the atomization chamber. When the atomizer is working, the atomized liquid in the oil cup 1 enters the oil guide body 232 through the liquid inlet channel 2211, and then is guided to the heating part of the planar heating wire 231 along the material texture of the oil guide body 232 and the surface texture of the oil guide body 232. The heating part atomizes the atomized liquid at the corresponding position of the oil guide body 232 into an aerosol in the atomization chamber. The aerosol is then exported through the bracket 221 and the outlet channel for the user to inhale.

[0045] Furthermore, the first side surface S1 and / or the second side surface S2 are provided with surface textures extending along the longitudinal direction. The surface textures in the longitudinal direction of the oil guide body 232 give the surface of the oil guide body 232 a concave-convex structure, which is not a completely flat surface. When it comes into contact with the flat heating wire 231, it has a larger contact area, better contact effect, and better atomization effect.

[0046] In this embodiment, the oil guide body 232 includes at least two oil guide layers stacked in the thickness direction, which is the normal direction of the first side surface S1. Each oil guide layer has surface textures extending along its longitudinal direction. The surface textures improve the adhesion between adjacent oil guide layers, thereby adjusting the oil guiding efficiency at the contact surface of adjacent oil guide layers. Specifically, the surface textures are preferably straight, and gaps are formed between adjacent surface textures of the same oil guide layer. The surface textures of the oil guide body 232 are embedded in the gaps between adjacent oil guide bodies 232. The surface textures are spaced apart in the width direction of the oil guide layer, and the width of the gaps between adjacent surface textures is preferably equal, thereby improving the oil guiding efficiency while ensuring the uniformity of oil guiding.

[0047] In some embodiments, the width of the gap between surface textures near the middle of the oil-guiding layer can be greater than the width of the gap between surface textures near the edge. This arrangement allows for different oil guiding efficiencies in different areas of the oil-guiding body 232. The heating part of the planar heating wire 231 is mainly located in the middle of the oil-guiding body 232. Therefore, by setting the width of the gap between surface textures in the middle to be larger, it is more conducive to the conduction of atomizing liquid to the area of ​​the heating part, thereby ensuring sufficient oil supply, preventing wicking, and improving the vaping experience. Of course, the width of the gap between surface textures can be adaptively adjusted according to the actual position of the heating part of the planar heating wire 231, as long as the width of the gap between surface textures in the concentrated heating area is greater than the width of the gap between surface textures in the heating edge area.

[0048] In this embodiment, the oil-conducting layer near the assembly side of the planar heating wire 231 has stronger temperature resistance and moisture retention than the oil-conducting layer far from the assembly side of the planar heating wire 231. The oil-conducting rate of the oil-conducting layer far from the assembly side of the planar heating wire 231 is faster than that of the oil-conducting layer near the assembly side of the planar heating wire 231. The saturated oil absorption per unit volume of the oil-conducting layer far from the assembly side of the planar heating wire 231 is greater than that of the oil-conducting layer near the assembly side of the planar heating wire 231.

[0049] After assembling the oil guide 232 and the planar heating wire 231, the oil guide layer closer to the assembly side of the planar heating wire 231 has stronger temperature resistance and moisture retention than the oil guide layer farther away from the assembly side. This makes it easier for the planar heating wire 231 to be wetted with atomizing oil, reducing the likelihood of dry burning. Furthermore, the oil guide layer in close contact with the planar heating wire 231 has stronger temperature resistance, making it less prone to wicking. In addition, the oil guide layer farther away from the assembly side of the planar heating wire 231 has a faster oil conduction rate than the oil guide layer closer to the assembly side of the planar heating wire 231. The saturated oil absorption per unit volume of the oil guide layer farther away from the assembly side of the planar heating wire 231 is greater than that of the oil guide layer closer to the assembly side of the planar heating wire 231. This allows the atomizing liquid in the oil cup 1 to be conducted to the planar heating wire 231 more quickly, ensuring oil supply and further reducing the risk of wicking.

[0050] Specifically, the oil guide body 232 includes a first oil guide layer 2321 and a second oil guide layer 2322 stacked on one side of the first oil guide layer 2321. Both the first oil guide layer 2321 and the second oil guide layer 2322 are two-layer spunlace nonwoven fabrics.

[0051] Preferably, the first oil-conducting layer 2321 can be made of at least one of viscose fiber, high-tenacity fiber, modal fiber, Tencel, lyocell fiber, Lenzing fiber, Asahi Kasei fiber, cupro fiber, binchotan charcoal, bamboo charcoal, etc., and the second oil-conducting layer 2322 can be made of at least one of cotton fiber, kapok fiber, hemp fiber, bamboo fiber, lotus fiber, tea fiber, aramid 1313, aramid 1414, polyimide, etc. In this embodiment, during assembly, the first oil-conducting layer 2321 and the planar heating wire 231 are assembled by plane-to-plane bonding. The second oil-conducting layer 2322 is located on the side of the first oil-conducting layer 2321 away from the planar heating wire 231, and the edge of the second oil-conducting layer 2322 is held in place by the bracket 221. It should be understood that the first oil-conducting layer 2321 has stronger temperature resistance and moisture retention than the second oil-conducting layer 2322, the oil conduction rate of the second oil-conducting layer 2322 is faster than that of the first oil-conducting layer 2321, and the saturated oil absorption per unit volume of the second oil-conducting layer 2322 is greater than that of the first oil-conducting layer 2321. It can be understood that by setting the materials of the first oil-conducting layer 2321 and the second oil-conducting layer 2322, the oil-conducting body 232 can have good heat resistance and good oil conduction ability to ensure oil supply and improve the suction experience.

[0052] Furthermore, the oil guide body 232 may also include a third oil guide layer 2323 stacked on the side opposite to the first oil guide layer 2321 of the second oil guide layer 2322. The first oil guide layer 2321 and the third oil guide layer 2323 are symmetrically arranged with respect to the second oil guide layer 2322, and the material of the third oil guide layer 2323 is the same as that of the first oil guide layer 2321. Preferably, the characteristics of the first oil-guiding layer 2321 and the third oil-guiding layer 2323 can be the same, that is, the oil-guiding body 232 does not have a front and back. When assembling the oil-guiding body 232 and the flat heating wire 231, both the first oil-guiding layer 2321 and the third oil-guiding layer 2323 can be assembled with the flat heating wire 231 by a plane-to-plane bonding method. Therefore, the oil-guiding body 232 does not need to be foolproof during assembly, which is more conducive to the automated assembly of the oil-guiding body 232. For example, both the first oil-guiding layer 2321 and the third oil-guiding layer 2323 can be made of two layers of linen non-woven fabric, and the second oil-guiding layer 2322 in the middle can be made of two layers of viscose non-woven fabric. This is conducive to automated production, and the spillage has little impact on the taste.

[0053] Furthermore, the total thickness of the oil guide 232 is within 0.5-2.0 mm, preferably 1.2-1.6 mm, and the basis weight of a single layer of nonwoven fabric is 40-120 g / m². 2 Preferred concentration: 60-75g / m 2 .

[0054] In some embodiments, the oil guide body 232 can be integrally molded and can be made of at least one of viscose fiber, high-tenacity fiber, modal fiber, Tencel, lyocell fiber, Lenzing fiber, Asahi Kasei Corporation, cupro fiber, binchotan charcoal, bamboo charcoal, cotton fiber, kapok fiber, hemp fiber, bamboo fiber, lotus fiber, tea fiber, aramid 1313, aramid 1414, polyimide, etc.

[0055] In some embodiments, the oil guide body 232 may also include more than three oil guide layers, such as four, five, or six oil guide layers. Each oil guide layer may include one, two, or three layers of spunlace nonwoven fabric, and no specific limitation is made on its structural form here.

[0056] In this embodiment, the compression percentage of the oil guide body 232 in the thickness direction is greater than 5% and less than 70%, and the thickness direction is the normal direction of the first side surface S1. The oil guide body 232 can expand and deform when absorbing oil. The compression percentage is: (thickness of the oil guide body 232 before compression - thickness of the oil guide body 232 after compression) / thickness of the oil guide body 232 before compression.

[0057] The wicking body 232 and the flat heating wire 231 are assembled by a planar-to-planar bonding method. That is, during assembly, the wicking body 232 will not put excessive pressure on the flat heating wire 231. Therefore, during the assembly process, the flat heating wire 231 will not deform excessively due to the squeezing of the wicking body 232, thus preventing uneven gaps between the two. Moreover, after assembly, the wicking body 232 can slightly expand and deform after absorbing the atomizing liquid. The side of the wicking body 232 near the flat heating wire 231 will bulge and contact the flat heating wire 231. This can eliminate errors in the height direction, making the wicking body 232 and the flat heating wire 231 fit tightly during operation, preventing local dry burning and scorching of the coil, thereby improving the quality of the electronic atomizer.

[0058] Preferably, the compression percentage of the oil guide body 232 is between 20% and 30%, such as 23%, 25%, 27%, etc. Using such a compression percentage parameter can make the oil guide body 232 more convenient and faster in the molding process. On the other hand, after the oil guide body 232 and the flat heating wire 231 are clamped and assembled by the base 211 and the bracket 221, the oil expansion amount of the oil guide body 232 is more appropriate. This can ensure the tightness of the fit between the oil guide body 232 and the flat heating wire 231 after absorbing oil, and can also make the squeezing force of the oil guide body 232 on the flat heating wire 231 moderate, so as not to cause excessive deformation of the flat heating wire 231, thereby improving the reliability of the atomizing core 23.

[0059] Furthermore, the wicking body 232 includes at least one fluffy area and an edge area surrounding each fluffy area, with the compression percentage of the edge area being less than that of the fluffy area. The edge area of ​​the wicking body 232 is more tightly compressed, achieving better oil control and preventing leakage, while the fluffy area can be used for the transmission of atomizing liquid, having a higher wicking rate, which is more conducive to the transmission of atomizing liquid through the wicking body 232 to the planar heating wire 231, thereby ensuring the supply of e-liquid and guaranteeing the vaping experience.

[0060] In this embodiment, the oil guide body 232 includes at least two oil guide portions 232a and a connecting portion 232b connecting each oil guide portion 232a. The oil guide portion 232a includes at least one fluffy area, the connecting portion 232b is a fluffy area, and the connecting portion 232b is integrated with the fluffy area in each oil guide portion 232a. Specifically, the bracket 221 has two symmetrical liquid inlet channels 2211, and the oil guide body 232 has a symmetrical structure, that is, the oil guide body 232 includes two symmetrically arranged oil guide parts 232a and a connecting part 232b connecting the oil guide parts 232a. When assembling the oil guide body 232, the two oil guide parts 232a are respectively arranged corresponding to the two liquid inlet channels 2211. The edge area of ​​the oil guide part 232a is clamped and fixed between the base 211 and the bracket 221. Since the edge area is pressed more tightly, the oil control and oil prevention performance is better. The fluffy area of ​​the oil guide part 232a is directly opposite the liquid inlet channel 2211, and the connecting part 232b is also a fluffy area. The heating part of the planar heating wire 231 is attached to one side of the connecting part 232b, which is more conducive to the conduction of atomizing liquid from both ends to the middle, thereby ensuring the oil supply of the heating part.

[0061] Preferably, the oil guide 232 is compressed by the base 211 and the top component 22 by 0-0.2mm. That is, there can be a compressive force between the oil guide 232 and the bracket 221. After the oil guide 232 absorbs oil and expands, it can be clamped and fixed stably by the base 211 and the top component 22. This can ensure that the oil guide 232 will not fall off between the base 211 and the top component 22 due to vibration during transportation or automated assembly of the atomizer.

[0062] Furthermore, a notch 232c is formed between the connecting portion 232b and the adjacent oil guiding portion 232a. Specifically, the oil guiding body 232 has two notches 232c, which are symmetrically arranged on opposite sides of the oil guiding body 232. The arrangement of the two notches 232c facilitates the conduction of the aerosol formed in the atomization chamber to the outlet channel. Preferably, the ratio of the dimension h3 of the notch 232c in the width direction to the width dimension h1 of the oil guiding body 232 can be 10%-20%, and the ratio of the dimension h4 of the notch 232c in the length direction to the length dimension h2 of the oil guiding body 232 can be 20%-45%. Using such ratio settings can simultaneously ensure the smooth conduction of aerosol and ensure that the middle part of the oil guiding body 232 has sufficient oil guiding structure, thereby improving the vaping experience.

[0063] In some embodiments, the oil guide body 232 may also include a connecting portion 232b and three, four, or five oil guide portions 232a connected to the outside of the connecting portion 232b. The bracket 221 is provided with liquid inlet channels 2211 corresponding to the oil guide portions 232a. The connecting portion 232b is a fluffy area, and the middle part of each oil guide portion 232a can be set as a fluffy area. The heating part of the planar heating wire 231 is attached to one side of the connecting portion 232b. Therefore, the atomizing liquid can be conducted to the connecting portion 232b through each oil guide portion 232a for heating and atomization by the planar heating wire 231.

[0064] Furthermore, the compression percentage of the fluffy zone can gradually decrease radially outward from its center. That is, the oil guiding performance in the middle of the fluffy zone is better than that in the outer part. Therefore, the middle part of the fluffy zone can be used to ensure the oil guiding performance, while the outer part of the fluffy zone is more conducive to oil control and leakage prevention because its oil guiding performance is relatively worse. In addition, since the compression percentage of the fluffy zone changes gradually, it can avoid the oil holding capacity and oil guiding rate differences in different areas of the oil guide body 232 being too obvious, thereby ensuring the uniformity of various properties of the oil guide body 232.

[0065] Furthermore, the ratio of the compression percentage of the fluffy region to the compression percentage of the edge region is within 1.5-10, preferably 2-3.

[0066] Furthermore, when the oil guide body 232 absorbs oil and expands, it is squeezed by the planar heating wire 231 to form an indentation of 0.01-0.2mm. Therefore, after absorbing oil, the oil guide body 232 is slightly higher than the contact surface of the planar heating wire 231, which can ensure that the surface of the heating wire facing the oil guide body 232 and its adjacent surfaces can contact the oil guide body 232, so as to output the atomized liquid to the three surfaces of the heating wire more quickly and ensure the atomization effect of the heating wire on the three surfaces.

[0067] Furthermore, the saturated oil absorption capacity of the oil guide 232 can be 600% to 1000%, where the saturated oil absorption capacity = (mass of the oil guide 232 after saturated oil absorption - mass of the oil guide 232 before oil absorption) / mass of the oil guide 232 before oil absorption. Preferably, the saturated oil absorption capacity is within 700%-800%, such as 725%, 750%, 775%, etc. Using the aforementioned parameter setting for the saturated oil absorption capacity ensures sufficient oil volume after the oil guide 232 absorbs oil, guaranteeing good atomization effect.
