本发明中导油体与现有技术相比，有益效果在于：Compared with the prior art, the oil guide body in the present invention has the beneficial effects of:
将导油体和平面发热丝装配后，由于靠近平面发热丝装配侧的导油层的耐温能力和保湿能力均强于远离平面发热丝装配侧的导油层，可以使得平面发热丝易于浸润于雾化油，更不容易出现干烧现象，而且，由于和平面发热丝贴紧的导油层耐温能力强，更不容易糊芯；此外，由于远离平面发热丝装配侧的导油层的导油速率快于靠近平面发热丝装配侧的导油层，远离平面发热丝装配侧的导油层的单位体积饱和吸油量大于靠近靠近平面发热丝装配侧的导油层，可以使得油杯内的雾化液更快地传导到平面发热丝处，保证供油量，进一步地降低了糊芯的风险。After the oil guide body and the flat heating wire are assembled, since the oil guide layer near the plane heating wire assembly side has stronger temperature resistance and moisture retention than the oil guide layer away from the plane heating wire assembly side, the plane heating wire can be easily soaked in the atomized oil, and dry burning is less likely to occur. Moreover, because the oil guide layer close to the plane heating wire has a strong temperature resistance, it is less likely to burn the core; The saturated oil absorption per unit volume of the oil guide layer on the side is greater than that of the oil guide layer near the assembly side of the flat heating wire, which can make the atomized liquid in the oil cup transfer to the flat heating wire faster, ensure the oil supply, and further reduce the risk of core burnt.

将导油体232和平面发热丝231装配后，由于靠近平面发热丝231装配侧的导油层的耐温能力和保湿能力均强于远离平面发热丝231装配侧的导油层，可以使得平面发热丝231易于浸润于雾化油，更不容易出现干烧现象，而且，由于和平面发热丝231贴紧的导油层耐温能力强，更不容易糊芯；此外，由于远离平面发热丝231装配侧的导油层的导油速率快于靠近平面发热丝231装配侧的导油层，远离平面发热丝231装配侧的导油层的单位体积饱和吸油量大于靠近靠近平面发热丝231装配侧的导油层，可以使得油杯1内的雾化液更快地传导到平面发热丝231处，保证供油量，进一步地降低了糊芯的风险。After the oil guiding body 232 and the flat heating wire 231 are assembled, since the oil guiding layer close to the flat heating wire 231 has better temperature resistance and moisture retention than the oil guiding layer away from the flat heating wire 231, the flat heating wire 231 is easy to soak in the atomized oil, and dry burning is less likely to occur. Moreover, because the oil guiding layer close to the flat heating wire 231 has a strong temperature resistance, it is less likely to burn the core; The oil transfer rate is faster than that of the oil transfer layer near the assembly side of the flat heating wire 231, and the saturated oil absorption per unit volume of the oil transfer layer far away from the assembly side of the flat heating wire 231 is greater than that of the oil transfer layer near the assembly side of the flat heating wire 231, which can make the atomized liquid in the oil cup 1 be transferred to the flat heating wire 231 faster, ensure the oil supply, and further reduce the risk of core burnt.

在一些实施例中，导油体232可以一体成型，导油体232可以由黏胶纤维、富强纤维、莫代尔纤维、天丝、莱赛尔纤维、兰精纤维、旭化成纤维、铜氨纤维、备长炭、竹炭、棉纤维、木棉纤维、麻纤维、竹纤维、莲纤维、茶纤维，芳纶1313、芳纶1414、聚酰亚胺等中的至少一种制成。In some embodiments, the oil guide body 232 can be integrally formed, and the oil guide body 232 can be made of at least one of viscose fiber, rich fiber, modal fiber, Tencel, lyocell fiber, Lenzing fiber, Asahi Kasei fiber, cupro ammonia fiber, Bincho charcoal, bamboo charcoal, cotton fiber, kapok fiber, hemp fiber, bamboo fiber, lotus fiber, tea fiber, aramid 1313, aramid 1414, polyimide and the like.
在一些实施例中，导油体232也可以包括不止三层的导油层，例如，包括四层、五层、六层导油层等设置方式，并且，每一导油层均可以包括一层、两层或三层等的水刺无纺布设置形式，在此并不对其结构形式做具体的限定。In some embodiments, the oil-guiding body 232 may also include more than three oil-guiding layers, for example, including four, five, six-layer oil-guiding layers, etc., and each oil-guiding layer may include one, two, or three layers of spunlace non-woven fabrics, and the structural form is not specifically limited here.
在本实施例中，导油体232在厚度方向的压缩百分比大于5％且小于70％，厚度方向为第一侧面S1的法线方向，导油体232在吸油时可膨胀变形，其中，压缩百分比＝(导油体232压缩前厚度-导油体232压缩后厚度)/导油体232压缩前厚度。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 S1, and the oil guide body 232 can expand and deform when absorbing oil, wherein, the compression percentage=(thickness of the oil guide body 232 before compression−the thickness of the oil guide body 232 after compression)/the thickness of the oil guide body 232 before compression.
导油体232和平面发热丝231通过平面和平面贴合装配的方式，即在装配时导油体232并不会给平面发热丝231造成过大的压力，因此，装配过程中平面发热丝231并不会因为受到导油体232的挤压而变形过度从而造成两者之间间隙不均匀的现象，而且，装配完成后导油体232吸收雾化液后可以轻微膨胀变形，导油体232的靠近平面发热丝231的侧面会鼓起而与平面发热丝231接触，这样可以消除高度方向的误差，使工作过程中的导油体232和平面发热丝231贴合紧密，不会出现局部干烧而糊芯的现象，从而提升电子雾化器的质量。The oil guide body 232 and the plane heating wire 231 are assembled by means of plane and plane fit, that is, the oil guide body 232 will not cause excessive pressure to the plane heating wire 231 during assembly, therefore, the plane heating wire 231 will not be excessively deformed due to being squeezed by the oil guide body 232 during the assembly process, resulting in an uneven gap between the two. It bulges and contacts the flat heating wire 231, which can eliminate the error in the height direction, so that the oil guide body 232 and the flat heating wire 231 fit closely during the working process, and there will be no phenomenon of local dry burning and core burnt, thereby improving the quality of the electronic atomizer.
优选的，导油体232的压缩百分比在20％-30％之间，例如23％、25％、27％等等，采用这样的压缩百分比参数一方面可以使得导油体232在成型过程中更加方便快捷，另一方面导油体232和平面发热丝231被底座211和支架221夹持装配之后，导油体232吸油膨胀量更为合适，可以保证导油体232吸油后和平面发热丝231之间的贴合紧密度，又可以使导油体232对平面发热丝231的挤压力适中，不会导致平面发热丝231过度变形，从而提升雾化芯23的可靠程度。Preferably, the compression percentage of the oil guide body 232 is between 20%-30%, such as 23%, 25%, 27% and so on. On the one hand, adopting such a compression percentage parameter can make the oil guide body 232 more convenient and quick during the molding process; The tightness of the fit can also make the pressure of the oil guide body 232 on the flat heating wire 231 moderate, and will not cause excessive deformation of the flat heating wire 231 , thereby improving the reliability of the atomizing core 23 .
进一步地，导油体232包括至少一蓬松区、以及围合于各蓬松区外的边缘区，边缘区的压缩百分比小于蓬松区的压缩百分比。导油体232的边缘区压合更加紧密，可以达到更好的控油防止漏液的效果，而蓬松区可以用于雾化液的传输，具有更高的导油速率，更有利于雾化液经过导油体232传输到平面发热丝231，从而保证供油量，以保证抽吸体验。Further, the oil guiding body 232 includes at least one fluffy area, and an edge area surrounding each fluffy area, and the compression percentage of the edge area is smaller than the compression percentage of the fluffy area. The edge area of the oil guide body 232 is more tightly pressed, which can achieve better oil control and prevent liquid leakage, while the fluffy area can be used for the transmission of atomized liquid, has a higher oil transfer rate, and is more conducive to the transfer of atomized liquid through the oil guide body 232 to the flat heating wire 231, so as to ensure the oil supply and ensure the suction experience.
在本实施例中，导油体232包括至少两导油部232a及连接于各导油部232a之间的连接部232b，导油部232a包括至少一蓬松区，连接部232b为蓬松区，且连接部232b与各导油部232a内的蓬松区连为一体。具体的，支架221上开设对称的两进液通道2211，导油体232为对称结构，即导油体232包括对称设置的两导油部232a和连接于导油部232a之间的连接部232b，在装配导油体232时，两导油部232a分别和两进液通道2211对应设置，导油部232a的边缘区被夹持固定于底座211和支架221之间，由于边缘区被压合得更加紧密，控油防油性能更好，而导油部232a的蓬松区正对于进液通道2211，且连接部232b也为蓬松区，平面发热丝231的发热部贴合在连接部232b的一侧，因此更有利于雾化液从两端向中部传导，从而保证发热部的供油量。In this embodiment, the oil guiding body 232 includes at least two oil guiding parts 232a and a connecting part 232b connected between each oil guiding part 232a, the oil guiding part 232a includes at least one fluffy area, the connecting part 232b is a fluffy area, and the connecting part 232b is integrated with the fluffy area in each oil guiding part 232a. Specifically, two symmetrical liquid inlet passages 2211 are provided on the bracket 221, 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 connected between the oil guide parts 232a. 1, because the edge area is pressed more tightly, the oil control and oil resistance performance is better, and the fluffy area of the oil guide part 232a is facing the liquid inlet channel 2211, and the connecting part 232b is also a fluffy area, and the heating part of the flat heating wire 231 is attached to one side of the connecting part 232b, so it is more conducive to the conduction of the atomized liquid from both ends to the middle, so as to ensure the oil supply of the heating part.
优选的，导油体232被底座211和顶部组件22挤压压缩0-0.2mm。即导油体232和支架221之间可以有挤压力度，在导油体232吸油膨胀后导油体232可以被底座211和顶部组件22夹持固定稳定，可以确保雾化器在运输途中、自动化组装过程中因振动而使导油体232从底座211和顶部组件22之间脱落。Preferably, the oil guiding body 232 is squeezed and compressed by 0-0.2 mm by the base 211 and the top component 22 . That is, there can be a pressing force between the oil guide body 232 and the bracket 221. After the oil guide body 232 absorbs oil and expands, the oil guide body 232 can be clamped and fixed by the base 211 and the top assembly 22, which can ensure that the oil guide body 232 falls off from between the base 211 and the top assembly 22 due to vibration during transportation and automatic assembly of the atomizer.
进一步地，连接部232b和相邻的导油部232a之间形成缺口232c。具体的，导油体232具有两个缺口232c，两缺口232c对称地设置于导油体232相对的两侧，两个缺口232c的设置利于气溶胶经其传导到导出通道，优选的，缺口232c在导油体232宽度方向上的尺寸h3和导油体232的宽度尺寸h1的比值可以为10％-20％，缺口232c在导油体232长度方向上的尺寸h4和导油体232的长度尺寸h2的比值可以为20％-45％，采用这样的比值设定可以同时保证气溶胶传导的通畅性，保证导油体232的中部具有足够的导油结构，从而提升抽吸体验。Further, a gap 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, and the two notches 232c are arranged symmetrically on opposite sides of the oil guiding body 232. The arrangement of the two notches 232c facilitates the conduction of the aerosol to the outlet channel through them. The ratio of the dimension h4 on the top to the length dimension h2 of the oil guide body 232 can be 20%-45%. Using such a ratio setting can simultaneously ensure the smooth conduction of the aerosol and ensure that the middle part of the oil guide body 232 has a sufficient oil guide structure, thereby improving the suction experience.
在一些实施例中，导油体232也可以包括一个连接部232b以及三个、四个、五个等连接于连接部232b的外侧的导油部232a，支架221设置和导油部232a一一对应的进液通道2211，连接部232b为蓬松区，各导油部232a的中部均可以设置为蓬松区，平面发热丝231的发热部贴设于连接部232b的一侧，因此，雾化液可以通过各导油部232a传导至连接部232b，以供平面发热丝231加热雾化。In some embodiments, the oil guiding body 232 may also include a connecting portion 232b and three, four, five, etc. oil guiding portions 232a connected to the outside of the connecting portion 232b. The bracket 221 is provided with a liquid inlet channel 2211 corresponding to the oil guiding portion 232a. The connecting portion 232b is a fluffy area, and the middle of each oil guiding portion 232a can be set as a fluffy area. Therefore, the atomizing liquid can be conducted to the connecting portion 232b through each oil guide portion 232a, so as to be heated and atomized by the planar heating wire 231.
进一步地，蓬松区的压缩百分比可以自其中心径向朝外逐渐缩小，即蓬松区的中部的导油性能相对于其外部的导油性能更好，因此，蓬松区的中部可以用于保证导油性能，蓬松区的外围由于导油性能相对来说更差更有利于控油防漏，此外，由于蓬松区的压缩百分比是逐渐变化的，可以避免导油体232相近区域不同处的持油量以及导油速率差异过于明显，从而保证导油体232的各种性能的均匀性。Further, the compression percentage of the fluffy region can gradually decrease radially outward from the center, that is, the oil-conducting performance of the middle part of the fluffy region is better than that of the outer part, therefore, the middle part of the fluffy region can be used to ensure the oil-conducting performance, and the periphery of the fluffy region is more conducive to oil control and leakage prevention due to relatively poorer oil-conducting performance. In addition, because the compression percentage of the fluffy region changes gradually, it can avoid the oil holding capacity and the oil transfer rate difference in different parts of the oil-guiding body 232. 2 Uniformity of various properties.
进一步地，蓬松区的压缩百分比和边缘区的压缩百分比的比值在1.5-10内，优选为2-3。Further, the ratio of the compression percentage of the fluffy area to the compression percentage of the edge area is within 1.5-10, preferably 2-3.
进一步地，导油体232吸油膨胀时被平面发热丝231挤压形成0.01-0.2mm的压痕，因此，导油体232吸油后微高出平面发热丝231的接触面，可以保证发热丝的正对于导油体232的面以及其相邻面可以和导油体232接触，以便更快向发热丝三个面输出雾化液，保证发热丝在三个面的雾化效果。Furthermore, when the oil guide body 232 absorbs oil and expands, it is squeezed by the flat heating wire 231 to form an indentation of 0.01-0.2mm. Therefore, the oil guide body 232 is slightly higher than the contact surface of the plane heating wire 231 after absorbing oil, which can ensure that the surface of the heating wire facing the oil guide body 232 and its adjacent surface can contact the oil guide body 232, so as to output the atomized liquid to the three sides of the heating wire faster, and ensure the atomization effect of the heating wire on the three surfaces.
进一步地，导油体232的饱和吸油量可以为600％～1000％，其中，饱和吸油量＝(导油体232饱和吸油后质量-导油体232吸油前质量)/导油体232吸油前质量。优选的，饱和吸油量在700％-800％内，如725％、750％、775％等。采用前述饱和吸油量的参数设置可以使导油体232吸油后油量充足，保证雾化效果的良好。Further, the saturated oil absorption of the oil guide 232 can be 600%-1000%, wherein, the saturated oil absorption=(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 is within 700%-800%, such as 725%, 750%, 775% and so on. Adopting the parameter setting of the aforementioned saturated oil absorption amount can make the oil amount sufficient after the oil guide body 232 absorbs oil, and ensure a good atomization effect.
在本实施例中，导油体232的材料纹路沿着纵长方向延伸，第一侧面S1和/或第二侧面S2设置有沿着纵长方向延伸的表面纹。In this embodiment, the material lines of the oil guiding body 232 extend along the lengthwise direction, and the first side S1 and/or the second side S2 are provided with surface lines extending along the lengthwise direction.
导油体232在装配到雾化器中时，可以和平面发热丝231贴合装配，在雾化器的使用过程中，由于导油体232本身材质的延伸方向在纵长方向，即雾化液可以沿着材质的延伸方向传导，提升了雾化液的传导效率，有利于雾化液向平面发热丝231的发热集中区域传导，保证供油充足，不易糊芯，利于抽吸体验。此外，导油体232的表面设置有纵长方向上的表面纹，使得导油体232的表面具有凹凸结构，并非完全的平面，和平面发热丝231接触时具有更大的贴合面积，贴合效果更好，雾化效果更佳。When the oil guide body 232 is assembled into the atomizer, it can be fitted with the flat heating wire 231. During the use of the atomizer, since the material of the oil guide body 232 extends in the longitudinal direction, the atomized liquid can be conducted along the extending direction of the material, which improves the conduction efficiency of the atomized liquid and is conducive to the conduction of the atomized liquid to the heating concentrated area of the planar heating wire 231, ensuring sufficient oil supply, and is not easy to burn the core, which is good for the suction experience. In addition, the surface of the oil guide body 232 is provided with surface lines in the longitudinal direction, so that the surface of the oil guide body 232 has a concave-convex structure, not a complete plane, and has a larger bonding area when in contact with the flat heating wire 231, better bonding effect, and better atomization effect.
在本实施例中，各导油层的表面均设有沿着其纵长方向延伸的表面纹。表面纹的设置可以提高相邻导油层之间的贴合程度，从而调整相邻导油层的接触面处的导油效率。具体的，表面纹优选为直线状，并且，同一导油层的相邻的表面纹之间形成间隙，导油体232的表面纹嵌置于其相邻的导油体232的间隙中，各表面纹在导油层的宽度方向间隔排列，相邻的表面纹之间的间隙的宽度优选为相等，从而可以在提升导油效率的同时保证导油的均匀性。In this embodiment, the surface of each oil-conducting layer is provided with surface textures extending along its longitudinal direction. The setting of the surface texture can improve the bonding degree between the adjacent oil-conducting layers, thereby adjusting the oil-conducting efficiency at the contact surface of the adjacent oil-conducting layers. Specifically, the surface textures are preferably linear, and gaps are formed between adjacent surface textures of the same oil-guiding layer, and the surface textures of the oil-guiding body 232 are embedded in the gaps between its adjacent oil-guiding bodies 232. The surface textures are arranged at intervals in the width direction of the oil-guiding layer, and the widths of the gaps between adjacent surface textures are preferably equal, so that the oil-guiding uniformity can be guaranteed while improving the oil-guiding efficiency.
在一些实施例中，可以为靠近导油层中部的表面纹之间的间隙的宽度大于靠近边缘处的表面纹之间的间隙的宽度，采用这样的设置方式可以使得导油体232不同区域的导油效率不同，平面发热丝231的发热部主要位于导油体232的中部，因此，通过将中部的表面纹之间的间隙的宽度设置得更大更有利于雾化液传导至发热部的区域，从而保证供油的充足，不易糊芯，利于抽吸体验，当然，根据平面发热丝231的发热部的实际位置，表面纹之间的间隙的宽度大小可以适应性调整，只要保证发热集中区域的表面纹间隙的宽度大于发热边缘区域的表面纹间隙的宽度即可。In some embodiments, the width of the gap between the surface grooves near the middle of the oil-guiding layer is greater than the width of the gap between the surface grooves near the edge. Such an arrangement can make the oil-guiding efficiency in different regions of the oil-guiding body 232 different. The heating part of the planar heating wire 231 is mainly located in the middle of the oil-guiding body 232. Therefore, setting the width of the gap between the surface grooves in the middle to be larger is more conducive to the conduction of the atomized liquid to the heating part, thereby ensuring sufficient oil supply, not easy to burn the core, and facilitating the suction experience. Of course, according to the actual position of the heating part of the planar heating wire 231, the width of the gap between the surface grooves can be adjusted adaptively, as long as the width of the surface groove gap in the heating concentrated area is greater than the width of the surface groove gap in the heating edge area.
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其它实施例的相关描述。In the above-mentioned embodiments, the descriptions of each embodiment have their own emphases, and for parts not described in detail in a certain embodiment, reference may be made to relevant descriptions of other embodiments.
