[0039] The present embodiment provides an electronic atomization device (not shown), comprising a battery rod and an atomizer, the atomizer and the battery rod are plug-connected.

[0040] Among them, in combination Figures 1-3 The atomizer comprises an oil cup 1 and an atomization assembly 2, the atomization assembly 2 comprises a bottom assembly 21, a top assembly 22 mounted to the top end of the bottom assembly 21, and an atomization core 23; the top assembly 22 is mounted into the oil cup 1 and is in sealing connection with the inner wall of the oil cup 1; the bottom assembly 21 comprises a base 211 mounted to one end of the oil cup 1, and the atomization core 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 providing the atomization liquid in the oil cup 1 to the atomization core 23; the atomization core 23 comprises a planar heating wire 231 and an oil guide body 232 stacked together, the oil guide body 232 is located between the top assembly 22 and the planar heating wire 231 and is connected with the liquid inlet channel 2211.

[0041] Specifically, in the embodiment, the base 211 has an air inlet hole, the base 211 comprises a support portion, the middle portion of the support portion has an opening in communication with the air inlet hole, the bottom assembly 21 further comprises an electrode (not shown) arranged in the support portion, the planar heating wire 231 comprises a heating portion and a conductive portion extending along the two ends of the heating portion in the transverse direction, the conductive portion is carried 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 attached and assembled on the top surface of the planar heating wire 231, the top assembly 22 comprises a bracket 221 sleeved on the base 211 and a silica gel sealing member 222 sealingly connected between the bracket 221 and the oil cup 1, the liquid inlet channel 2211 is arranged in the bracket 221 and the sealing silica gel member, the bracket 221 and the base 211 jointly clamp and fix the oil guide body 232, and the oil guide body 232 covers the liquid inlet channel 2211 of the bracket 221, the bracket 221 and the base 211 form an atomization cavity therebetween, and the oil cup 1 has a guide-out channel in communication with the atomization cavity. When the atomizer works, 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 portion of the planar heating wire 231 along the oil guide body 232, the heating portion atomizes the atomized liquid at the corresponding position of the oil guide body 232 to form aerosol, and the aerosol is guided out through the bracket 221 and the guide-out channel for the user to smoke.

[0042] Further, in combination with Figure 3 The oil guide body 232 is attached and assembled with the planar heating wire 231, the oil guide body 232 comprises a first side surface S1 and a second side surface S2 arranged oppositely and parallelly, 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 surface S1, and the oil guide body 232 can be deformed by swelling when absorbing oil, wherein the compression percentage = (the 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.

[0043] The oil guide body 232 and the planar heating wire 231 are attached and assembled by the planar and planar attachment mode, that is, the oil guide body 232 does not cause excessive pressure to the planar heating wire 231 during assembly, therefore, the planar heating wire 231 does not deform excessively due to the extrusion of the oil guide body 232 during assembly, so as to cause the uneven gap between the two. Moreover, after assembly is completed, the oil guide body 232 can be slightly deformed by swelling after absorbing the atomized liquid, the side surface of the oil guide body 232 close to the planar heating wire 231 can be bulged to contact the planar heating wire 231, so as to eliminate the error in the height direction, so that the oil guide body 232 and the planar heating wire 231 are closely attached during work, and the local dry burning and core burning phenomenon is avoided, so as to improve the quality of the electronic atomizer.

[0044] Preferably, 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, on the one hand, the oil guide body 232 can be more convenient and fast during the molding process, and on the other hand, after the oil guide body 232 and the planar heating wire 231 are clamped and assembled by the base 211 and the support 221, the oil guide body 232 has a more appropriate oil absorption expansion amount, which can ensure the close fit between the oil guide body 232 and the planar heating wire 231 after oil absorption, and can also make the extrusion force of the oil guide body 232 on the planar heating wire 231 moderate, so as not to cause excessive deformation of the planar heating wire 231, thereby improving the reliability of the atomizing core 23.

[0045] Further, the oil guide 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 less than that of the fluffy area. The edge area of the oil guide body 232 is compressed more tightly, which can achieve a better oil control effect and prevent liquid leakage, while the fluffy area can be used for the transmission of atomized liquid, has a higher oil guide rate, and is more conducive to the transmission of atomized liquid through the oil guide body 232 to the planar heating wire 231, thereby ensuring the oil supply amount to ensure the suction experience.

[0046] In the embodiment, the oil guide body 232 includes at least two oil guide portions 232a and a connecting portion 232b connected between the oil guide portions 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 support 221 is provided with two symmetrical liquid inlet channels 2211, the oil guide body 232 is a symmetrical structure, i.e., the oil guide body 232 includes two symmetrical oil guide portions 232a and a connecting portion 232b connected between the oil guide portions 232a, when the oil guide body 232 is assembled, the two oil guide portions 232a are respectively arranged corresponding to the two liquid inlet channels 2211, and the edge area of the oil guide portion 232a is clamped and fixed between the base 211 and the support 221. Since the edge area is compressed more tightly, the oil control performance is better, while the fluffy area of the oil guide portion 232a is opposite to the liquid inlet channel 2211, and the connecting portion 232b is also a fluffy area, and the heating portion of the planar heating wire 231 is attached to one side of the connecting portion 232b, so it is more conducive to the conduction of atomized liquid from both ends to the middle, thereby ensuring the oil supply amount of the heating portion.

[0047] Preferably, the oil guide body 232 is extruded and compressed by 0-0.2mm by the base 211 and the top assembly 22. That is, there can be an extrusion force between the oil guide body 232 and the support 221, and after the oil guide body 232 is expanded by absorbing oil, the oil guide body 232 can be clamped and fixed stably by the base 211 and the top assembly 22, which can ensure that the atomizer does not fall off from the base 211 and the top assembly 22 due to vibration during transportation and automatic assembly process.

[0048] 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 gaps 232c, which are symmetrically arranged on opposite sides of the oil guiding body 232. The arrangement of the two gaps 232c facilitates the conduction of the aerosol formed in the atomization cavity to the guiding channel. Preferably, the ratio of the size h3 of the gap 232c in the width direction of the oil guiding body 232 to the width size h1 of the oil guiding body 232 can be 10%-20%, and the ratio of the size h4 of the gap 232c in the length direction of the oil guiding body 232 to the length size h2 of the oil guiding body 232 can be 20%-45%. The adoption of such ratio can ensure the smoothness of the conduction of the aerosol and the sufficient oil guiding structure of the middle part of the oil guiding body 232, thereby improving the smoking experience.

[0049] In some embodiments, the oil guiding body 232 can also include one connecting portion 232b and three, four, five or more oil guiding portions 232a connected to the outer side of the connecting portion 232b. The support 221 is provided with one liquid inlet channel 2211 corresponding to each oil guiding portion 232a. The connecting portion 232b is a fluffy area, and the middle part of each oil guiding portion 232a can also be arranged as a fluffy area. The heating portion of the planar heating wire 231 is arranged on one side of the connecting portion 232b. Therefore, the atomized liquid can be conducted to the connecting portion 232b through each oil guiding portion 232a for heating and atomization by the planar heating wire 231.

[0050] Further, the compression percentage of the fluffy area can gradually decrease from the center to the outside, i.e., the oil guiding performance of the middle part of the fluffy area is better than that of the outer part. Therefore, the middle part of the fluffy area can be used to ensure the oil guiding performance, and the outer part of the fluffy area is more suitable for oil control and leakage prevention due to the relatively poor oil guiding performance. In addition, since the compression percentage of the fluffy area gradually changes, the difference between the oil holding capacity and the oil guiding rate of the adjacent areas of the oil guiding body 232 can be avoided, thereby ensuring the uniformity of various performances of the oil guiding body 232.

[0051] 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.

[0052] Further, when the oil guiding body 232 is expanded by absorbing oil and is pressed by the planar heating wire 231, a 0.01-0.2mm indentation is formed. Therefore, the oil guiding body 232 can slightly protrude from the contact surface of the planar heating wire 231 after absorbing oil. The surface of the heating wire opposite to the oil guiding body 232 and the adjacent surface can contact the oil guiding body 232, so as to more quickly output the atomized liquid to the three surfaces of the heating wire and ensure the atomization effect of the heating wire on the three surfaces.

[0053] Further, the saturated oil absorption of the oil guide body 232 can be 600% to 1000%, wherein the saturated oil absorption = (mass of the oil guide body 232 after saturated oil absorption - mass of the oil guide body 232 before oil absorption) / mass of the oil guide body 232 before oil absorption. Preferably, the saturated oil absorption is within 700% to 800%, such as 725%, 750%, 775%, etc. The parameter setting of the foregoing saturated oil absorption can make the oil guide body 232 have sufficient oil after oil absorption, and ensure good atomization effect.

[0054] Further, the material lines of the oil guide body 232 extend along the longitudinal direction, and the first side surface S1 and / or the second side surface S2 are provided with surface lines extending along the longitudinal direction.

[0055] When the oil guide body 232 is assembled into the atomizer, it can be assembled in close contact with the planar heating wire 231. During use of the atomizer, since the extension direction of the material of the oil guide body 232 is in the longitudinal direction, i.e., the atomized liquid can conduct along the extension direction of the material, it is beneficial for the atomized liquid to conduct to the heating concentrated area of the planar heating wire 231, ensuring sufficient oil supply and preventing the wick from being burnt out, and facilitating the smoking 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, and is not a complete plane. When the oil guide body 232 is in contact with the planar heating wire 231, it has a larger contact area and better close contact effect, and the atomization effect is better.

[0056] In the present embodiment, the oil guide body 232 includes at least two oil guide layers stacked in the thickness direction, and the thickness direction is the normal direction of the first side surface S1. The surface of each oil guide layer is provided with surface lines extending along the longitudinal direction thereof. The arrangement of the surface lines can improve the close contact degree between adjacent oil guide layers, thereby adjusting the oil guiding efficiency at the contact surface of adjacent oil guide layers. Specifically, the surface lines are preferably linear, and adjacent surface lines of the same oil guide layer form a gap. The surface lines of the oil guide body 232 are embedded in the gap of the adjacent oil guide body 232. Each surface line is arranged in the width direction of the oil guide layer, and the width of the gap between adjacent surface lines is preferably equal, so that the oil guiding efficiency can be improved while ensuring the uniformity of oil guiding.

[0057] In some embodiments, the width of the gap between the surface lines near the middle of the oil guide layer is greater than the width of the gap between the surface lines near the edge. In this way, the oil guiding efficiency of different regions of the oil guide body 232 can be made different. The heating part of the planar heating wire 231 is mainly located in the middle of the oil guide body 232. Therefore, by setting the width of the gap between the surface lines in the middle to be greater, the atomized liquid is more conducive to being conducted to the region of the heating part, thereby ensuring sufficient oil supply and preventing core sticking, and improving the smoking 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 width of the gap between the surface lines in the heating concentrated region is greater than the width of the gap between the surface lines in the heating edge region.

[0058] In the present embodiment, the temperature resistance and moisture retention of the oil guide layer near the assembly side of the planar heating wire 231 are stronger than those of the oil guide layer away from the assembly side of the planar heating wire 231. The oil guiding rate of the oil guide layer away from the assembly side of the planar heating wire 231 is faster than that of the oil guide layer near the assembly side of the planar heating wire 231. The unit volume saturated oil absorption of the oil guide layer away from the assembly side of the planar heating wire 231 is greater than that of the oil guide layer near the assembly side of the planar heating wire 231.

[0059] After the oil guide body 232 and the planar heating wire 231 are assembled, since the temperature resistance and moisture retention of the oil guide layer near the assembly side of the planar heating wire 231 are stronger than those of the oil guide layer away from the assembly side of the planar heating wire 231, the planar heating wire 231 is easy to be soaked in the atomized oil and is less likely to dry out. Moreover, since the temperature resistance of the oil guide layer close to the planar heating wire 231 is strong, the risk of core sticking is further reduced. In addition, since the oil guiding rate of the oil guide layer away from the assembly side of the planar heating wire 231 is faster than that of the oil guide layer near the assembly side of the planar heating wire 231, and the unit volume saturated oil absorption of the oil guide layer away from the assembly side of the planar heating wire 231 is greater than that of the oil guide layer near the assembly side of the planar heating wire 231, the atomized liquid in the oil cup 1 can be more quickly conducted to the planar heating wire 231, thereby ensuring the oil supply and further reducing the risk of core sticking.

[0060] Further, 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.

[0061] Preferably, the first oil guide layer 2321 can be made of at least one of viscose fiber, strong fiber, modal fiber, Tencel, Lyocell fiber, ramie fiber, Asahi Kasei fiber, cuprammonium fiber, Kozo carbon fiber, bamboo charcoal, etc., and the second oil guide 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, when assembling, the first oil guide layer 2321 and the planar heating wire 231 are assembled by the planar and planar lamination method, the second oil guide layer 2322 is located on the side of the first oil guide layer 2321 away from the planar heating wire 231, and the edge of the second oil guide layer 2322 is tightly pressed by the support 221. It should be understood that the temperature resistance and moisture retention of the first oil guide layer 2321 are stronger than those of the second oil guide layer 2322, the oil guiding rate of the second oil guide layer 2322 is faster than that of the first oil guide layer 2321, and the unit volume saturated oil absorption of the second oil guide layer 2322 is greater than that of the first oil guide layer 2321. It can be understood that by setting the materials of the first oil guide layer 2321 and the second oil guide layer 2322, the oil guide body 232 can have good heat resistance and good oil guiding capacity to ensure the oil supply and improve the smoking experience.

[0062] Further, the oil guide body 232 can further include a third oil guide layer 2323 stacked on the side of the second oil guide layer 2322 away from the first oil guide layer 2321, the first oil guide layer 2321 and the third oil guide layer 2323 are symmetrically arranged relative 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 first oil guide layer 2321 and the third oil guide layer 2323 can have the same properties, i.e., the oil guide body 232 has no front and back, and when assembling the oil guide body 232 and the planar heating wire 231, the first oil guide layer 2321 and the third oil guide layer 2323 can be assembled with the planar heating wire 231 by the planar and planar lamination method. Therefore, the oil guide body 232 does not need to be prevented from being assembled, which is more conducive to the automatic assembly of the oil guide body 232.
