One side of the wire 231, and the edge of the second oil-guiding layer 2322 is pressed against by the bracket 221. It should be understood that the temperature resistance and moisture retention capacity of the first oil-guiding layer 2321 are stronger than that of the second oil-guiding layer 2322, and the second oil-guiding layer 2322 The oil-conducting rate of 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. The setting can make the oil guiding body 232 have good heat resistance and good oil guiding ability, so as to ensure the oil supply and improve the suction experience.

The oil-guiding body 232 may also include a third oil-guiding layer 2323 stacked on the side of the second oil-guiding layer 2322 away from the first oil-guiding layer 2321 , the first oil-guiding layer 2321 and the third oil-guiding layer 2323 are arranged symmetrically with respect to the second oil-guiding layer 2322 , the material of the third oil-guiding layer 2323 is the same as that of the first oil-guiding layer 2321 . 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 has no positive and negative points. The oil layer 2323 can be assembled with the flat heating wire 231 by plane and plane bonding, therefore, the oil guide body 232 does not need to be fool-proof during assembly, which is more conducive to the automatic assembly of the oil guide body 232, for example, the first oil guide layer 2321 Both the second oil-guiding layer 2322 and the third oil-guiding layer 2323 can adopt two layers of flax non-woven fabrics, and the second oil-guiding layer 2322 in the middle can adopt two layers of viscose non-woven fabrics, which is conducive to automatic production and has little impact on taste if scattered.

The total thickness of the oil guiding body 232 is within 0.5-2.0 mm, for example, 1.2-1.6 mm, and the weight of the single-layer non-woven fabric is 40-120 g/m2, for example, 60-75 g/m2.

In some embodiments, the oil guide body 232 can be integrally formed, and the oil guide body 232 can be made of viscose fiber, rich fiber, modal fiber, tencel, lyocell fiber, Lenzing fiber, Asahi Kasei fiber, cupro ammonia fiber, Long charcoal, bamboo charcoal, cotton fiber, kapok fiber, hemp fiber, bamboo fiber, lotus fiber, tea fiber, at least one of aramid 1313, aramid 1414, polyimide and the like.

In some embodiments, the oil guide body 232 may also include more than three oil guide layers, for example, including four, five, six oil guide layers, etc., and each oil guide layer may include one, two or more oil guide layers. The arrangement form of the spunlace nonwoven fabric such as one layer or three layers is not specifically limited here.

In this embodiment, the compression percentage of the oil guide body 232 in the thickness direction is greater than 5% and less than 70%, 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 Percentage = (thickness of oil guide body 232 before compression - thickness of oil guide body 232 after compression) / thickness of oil guide body 232 before compression, and the thickness of oil guide body after compression is after applying a pressure of 3000~4000N/ ^m2 to the oil guide body Measured.

The oil guide body 232 and the plane heating wire 231 are assembled by plane and plane, 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 It will not be excessively deformed due to being squeezed by the oil guide body 232, resulting in uneven gap between the two. Moreover, after the assembly is completed, the oil guide body 232 can slightly expand and deform after absorbing the atomized liquid, and the oil guide body 232 The side near the plane heating wire 231 will bulge and contact the plane heating wire 231, which can eliminate the error in the height direction, so that the oil guide body 232 and the plane heating wire 231 in the working process are closely bonded, and local dryness will not occur. The phenomenon of burning and burning the core, thus improving the quality of the electronic atomizer.

The compression percentage of the oil guide body 232 is between 20%-30%, such as 23%, 25%, 27%, etc. Using such a compression percentage parameter can make the oil guide body 232 more convenient and quicker in the molding process on the one hand On the other hand, after the oil guide body 232 and the plane heating wire 231 are clamped and assembled by the base 211 and the bracket 221, the oil-absorbing expansion of the oil guide body 232 is more appropriate, which can ensure that the oil guide body 232 and the plane heating wire 231 are in contact with each other after absorbing oil. The tightness of bonding 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.

The oil guiding body 232 includes at least one fluffy area, and edge areas 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 pressed more tightly, which can achieve better oil control and prevent liquid leakage, while the fluffy area can be used for the transmission of atomized liquid, which has a higher oil conduction rate and is more conducive to the atomized liquid The oil is transmitted to the flat heating wire 231 through the oil guide body 232, so as to ensure the amount of oil supplied and ensure the suction experience.

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 portion 232b is integrally connected with the fluffy area in each oil guiding portion 232a. Specifically, two symmetrical liquid inlet passages 2211 are opened on the bracket 221, and the oil guiding body 232 has a symmetrical structure, that is, the oil guiding body 232 includes two symmetrically arranged oil guiding parts 232a and a connecting part 232b connected between the oil guiding parts 232a. When assembling the oil guiding body 232, the two oil guiding parts 232a are arranged correspondingly to the two liquid inlet passages 2211 respectively, and the edge area of the oil guiding part 232a is clamped and fixed between the base 211 and the bracket 221. Since the edge areas are pressed together 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 plane heating wire 231 is attached to a part of the connecting part 232b. side, so it is more conducive to the transfer of atomized liquid from both ends to the middle, so as to ensure the oil supply of the heating part.

The oil guiding body 232 is squeezed and compressed by 0-0.2 mm by the base 211 and the top assembly 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 component 22, which can ensure that the atomizer is in transit. During the automatic assembly process, the oil guiding body 232 falls off from between the base 211 and the top assembly 22 due to vibration.

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 gaps 232c, and the two gaps 232c are symmetrically arranged on opposite sides of the oil guiding body 232. The ratio of the dimension h3 in the width direction of the oil body 232 to the width dimension h1 of the oil guide body 232 can be 10%-20%, the size h4 of the notch 232c in the length direction of the oil guide body 232 and the length dimension h2 of the oil guide body 232 The ratio 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.

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. Corresponding to the liquid inlet channel 2211, the connecting part 232b is a fluffy area, and the middle part of each oil guide part 232a can be set as a fluffy area, and the heating part of the plane heating wire 231 is attached to one side of the connecting part 232b. Therefore, the atomized liquid The oil can be conducted to the connection part 232b through each oil guide part 232a, so as to be heated and atomized by the planar heating wire 231.

The compression percentage of the fluffy region can gradually decrease radially outward from its center, that is, the oil conduction performance of the middle part of the fluffy region is better than that of its outer part, therefore, the middle part of the fluffy region can be used to ensure the oil conduction performance, The periphery of the fluffy area is relatively poorer in oil conduction performance, which is more conducive to oil control and leakage prevention. In addition, since the compression percentage of the fluffy area changes gradually, it can avoid the oil holding capacity and oil conduction at different places in the vicinity of the oil guide body 232. The speed difference is too obvious, so as to ensure the uniformity of various performances of the oil guide body 232 .

The ratio of the percent compression of the fluffy region to the percent compression of the edge region is within 1.5-10, for example 2-3.

When the oil guide body 232 absorbs oil and expands, it is squeezed by the flat heating wire 231 to form an indentation of 0.01-0.2 mm. 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 heating wire is directly facing the guide wire. The surface of the oil body 232 and its adjacent surfaces can be in contact with the oil guide body 232, so as to output the atomized liquid to the three surfaces of the heating wire faster, and ensure the atomization effect of the heating wire on the three surfaces.

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. The saturated oil absorption is within 700%-800%, such as 725%, 750%, 775%, etc. 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.

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.

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, that is, the atomization The liquid can be conducted along the extension 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 flat heating wire 231, ensuring sufficient oil supply, not easy to burn the core, and conducive to 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, which is not completely flat, and has a larger bonding area when it contacts with the flat heating wire 231. The combination effect is better, and the atomization effect is better.

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 texture can be linear, and a gap is formed between adjacent surface textures of the same oil-guiding layer, and the surface texture of the oil-guiding body 232 is embedded in the gap between its adjacent oil-guiding bodies 232, and each surface The grooves are arranged at intervals in the width direction of the oil-conducting layer, and the widths of the gaps between adjacent surface grooves can be equal, so that the oil-conducting efficiency can be improved while the oil-conducting uniformity can be ensured.

In some embodiments, the width of the gap between the surface grooves near the middle of the oil-guiding layer may be greater than the width of the gap between the surface grooves near the edge. Such an arrangement can make the guides in different regions of the oil-guiding body 232 The oil efficiency is different. The heating part of the plane heating wire 231 is mainly located in the middle of the oil guide body 232. Therefore, setting the width of the gap between the surface lines in the middle to be larger is more conducive to the conduction of the atomized liquid to the heating part. , so as to ensure sufficient oil supply, it is not easy to burn the core, and it is beneficial to 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 lines can be adjusted adaptively, as long as the heating concentration area is ensured It is enough that the width of the gap between the surface grains is larger than the width of the gap between the surface grains in the heating edge region.
