The material pattern is formed by arranging the materials forming the oil guide 232 in the longitudinal direction, for example, when the fiber materials are used, the fiber materials are arranged along the longitudinal direction, and the fiber materials and the gaps between the fiber materials form the material pattern together.

When the oil guide body 232 is assembled into the atomizer, the plane heating wires 231 can be attached and assembled, and in the using process of the atomizer, as the extending direction of the material of the oil guide body 232 is in the longitudinal direction, i.e. atomized liquid can be conducted along the extending direction of the material, the conducting efficiency of the atomized liquid is improved, the atomized liquid is conductive to the heating concentrated area of the plane heating wires 231, the oil supply is sufficient, the core is not easy to paste, and the suction experience is facilitated.

Further, the first side S1 and/or the second side S2 are provided with surface textures extending in the longitudinal direction. The surface of the oil guide body 232 is provided with surface patterns in the longitudinal direction, so that the surface of the oil guide body 232 is provided with a concave-convex structure, is not a complete plane, and has a larger laminating area when the plane heating wires 231 are contacted, the laminating effect is better, and the atomization effect is better.

In this embodiment, the oil guide 232 includes at least two oil guide layers stacked in a thickness direction, the thickness direction is a normal direction of the first side surface S1, and each oil guide layer has a surface pattern extending along a longitudinal direction thereof.

Further, the oil guiding body 232 may further include a third oil guiding layer 2323 stacked on the second oil guiding layer 2322 and facing away from the first oil guiding layer 2321, where the first oil guiding layer 2321 and the third oil guiding layer 2323 are symmetrically disposed relative to the second oil guiding layer 2322, and the material of the third oil guiding layer 2323 is the same as that of the first oil guiding layer 2321. Preferably, the characteristics of the first oil guiding layer 2321 and the third oil guiding layer 2323 may be the same, that is, the oil guiding body 232 does not have front and back sides, when the oil guiding body 232 and the planar heating wire 231 are assembled, the first oil guiding layer 2321 and the third oil guiding layer 2323 can be assembled by the planar and planar heating wire 231 in a planar attached mode, so that the oil guiding body 232 does not need to be foolproof during assembly, and automatic assembly of the oil guiding body 232 is more facilitated, for example, the first oil guiding layer 2321 and the third oil guiding layer 2323 can both adopt two layers of flax non-woven fabrics, the second oil guiding layer 2322 located in the middle can adopt two layers of viscose non-woven fabrics, which is favorable for automatic production, and the influence on the mouth feel is not great.

Further, a notch 232c is formed between the connecting portion 232b and the adjacent oil guiding portion 232 a. Specifically, the oil guiding body 232 has two notches 232c, the two notches 232c are symmetrically disposed on two opposite sides of the oil guiding body 232, the arrangement of the two notches 232c is beneficial to conducting aerosol formed in the atomization cavity to the guiding channel, preferably, the ratio of the dimension h3 of the notch 232c in the width direction of the oil guiding body 232 to the width dimension h1 of the oil guiding body 232 can be 10% -20%, the ratio of the dimension h4 of the notch 232c in the length direction of the oil guiding body 232 to the length dimension h2 of the oil guiding body 232 can be 20% -45%, and by adopting such ratio setting, the smoothness of aerosol conduction can be ensured at the same time, and the middle part of the oil guiding body 232 is guaranteed to have a sufficient oil guiding structure, so that the suction experience is improved.

Further, the compression percentage of the fluffy region may be gradually reduced from the center to the outside in the radial direction, that is, the oil guiding performance of the middle part of the fluffy region is better than that of the outer part of the fluffy region, so that the middle part of the fluffy region may be used for ensuring the oil guiding performance, the periphery of the fluffy region is more beneficial to oil control and leakage prevention due to relatively poorer oil guiding performance, and in addition, the compression percentage of the fluffy region is gradually changed, so that the oil holding capacity and the oil guiding rate difference at different positions of the similar region of the oil guiding body 232 are prevented from being too obvious, thereby ensuring the uniformity of various performances of the oil guiding body 232.
