As shown in fig. 1, for the utility model discloses an atomizing core for electronic atomization device, including the portion of generating heat 1 that can electrically conduct, this atomizing core is still including connecting in the portion of generating heat 1 both sides can electrically conduct lead liquid portion 2, and lead liquid portion 2 and inhale the atomized liquid to the portion of generating heat 1 through capillary force and atomize, leads liquid portion 2 specifically including setting up the first liquid portion 21 and the second liquid portion 22 of leading in the relative both sides of the thickness direction of the portion of generating heat 1, adopts two-sided atomizing, has the big advantage that is makeed to atomize volume, and the liquid portion 2 of leading that is in both sides has generates heat, leads oil, oil storage and atomization function. The resistance value of the liquid guide part 2 is higher than that of the heating part 1, and the heating part 1 positioned at the middle is low in resistance value and plays a main heating role; first liquid guide portion 21 and second liquid guide portion 22 located on both sides of heat generating portion 1 are high in resistance value and function as auxiliary heat generation. Understandably, in some embodiments, the atomizing core may include an electrically conductive liquid conducting portion disposed on only one side of the heat generating portion 1, which may be adjusted according to practical situations, and is not limited herein.

Further, a first electrode 31 and a second electrode 32 are respectively disposed on opposite sides of the heat generating portion 1 in the longitudinal direction, and the heat generating portion 1 and the liquid guiding portion 2 are electrically conducted between the first electrode 31 and the second electrode 32 to generate heat. Specifically, the heat generating portion 1 includes a first side surface 101 and a second side surface 102 opposed to each other in the longitudinal direction, the first electrode 31 is provided on the first side surface 101, and the second electrode 32 is provided on the second side surface 102. Understandably, the first electrode 31 and the second electrode 32 comprise a positive electrode and a negative electrode with opposite polarities, and if the first electrode 31 is the positive electrode, the second electrode 32 is the negative electrode; conversely, if the first electrode 31 is a negative electrode, the second electrode 32 is a positive electrode. In addition, the heat generation area and the atomization area can be controlled by adjusting the setting height of the electrode.

In other embodiments, the heat generating portion 1 includes an electromagnetic heating unit, and the heat generating portion 1 generates heat by electromagnetic induction of the electromagnetic heating unit. The heat generating part 1 and/or the liquid guiding part 2 may be made of a material that can be heated by electromagnetic induction, and the atomizing core generates heat by electromagnetic induction without changing its form and structure, and accordingly, an electrode structure may be omitted. Specifically, the heat generating part 1 is placed right in the middle of the circumferential magnetic field, so that the heat generating part 1 is a main induction heating area, and the liquid guide part 2 generates relatively less heat. When the heating part 1 and the liquid guiding part 2 are made of materials capable of being heated by electromagnetic induction, the electromagnetic induction heating can be realized according to the set magnetic permeability, the middle heating part 1 still has the main heating function, and the liquid guiding part 2 has the auxiliary heating function.

Further, for the heat generating portion 1 in which the middle is surface heat generation, the structure of the heat generating portion 1 may be a dense structure or a porous structure, and specifically, the heat generating portion 1 may be a heat generating circuit (e.g., a thick film heat generating circuit), a heat generating wire, a dense full-surface heat generating layer, or a full-surface heat generating layer having a porous structure. When the middle heating part 1 is a compact full-page heating layer, the middle heating part can also provide strength support for the atomizing core. Specifically, the heat generating member 1 may be made of metal, cermet, metallic glass, or conductive ceramic and composite oxide thereof. The metal ceramic is prepared by compounding at least one of metal or metal alloy and a ceramic material, wherein the ceramic material has the functions of resistance adjustment and strength enhancement, and the ceramic material can be at least one of aluminum oxide, zirconium oxide, silicon oxide, yttrium oxide, lanthanum oxide, cerium oxide and magnesium oxide. By controlling the length-diameter ratio, the thickness and the porosity of the liquid guide part 2, the atomization amount in one suction process and the atomized liquid replenishing rate can be controlled.

Further, the shape of the liquid guiding portion 2 is preferably a square shape, but may be other shapes as necessary; understandably, the shape of the heat generating portion 1 may be similar to or different from the shape of the liquid guiding portion 2, and the size of the liquid guiding portion 2 may be the same as that of the heat generating portion 1, to achieve an efficient atomization effect. When the liquid guide part 2 is of a porous structure, the porosity of the liquid guide part can be between 30 and 80 percent, and the pore diameter range is between 10 and 100 mu m; the porous structure has high through-hole rate and provides a channel for the conduction of atomized liquid and the release of aerosol.

Further, the atomizing core also comprises a connecting part 7 for fixing or sealing, and the connecting part 7 extends axially along the liquid guide part 2. The connecting portion 7 is a non-fogging area, which is mainly used for fixing or sealing. In order to improve the energy efficiency and the atomization rate, it is necessary to minimize the heat transfer to the non-atomization region, and therefore the height of the non-atomization region should be shortened as much as possible, that is, the height of the connection part 7 should be smaller than the height of the liquid guide part 2, and the height of the connection part 7 should be as small as possible.

In consideration of the fact that the height of the non-atomization area is reduced, the sealing failure risk is caused, and the atomization area and the non-atomization area can be hollowed out. Therefore, as shown in fig. 4, the connecting portion 7 is further provided with the heat insulating groove 71, both ends in the longitudinal direction of the heat insulating groove 71 are positioned in the connecting portion 7, that is, the length of the heat insulating groove 71 is smaller than the length of the connecting portion 7, and the heat insulating groove 71 does not penetrate in the transverse longitudinal direction of the connecting portion 7. Specifically, the width of the heat insulation groove 71 is less than or equal to 1 mm, so as to ensure that the atomized liquid in the liquid storage chamber 4 can be adsorbed to the liquid guide groove by capillary force to complete atomization.

When the power is turned on, the middle heating part 1 has a small resistance and plays a primary heating role, and the liquid guide parts 2 on both sides have a large resistance and play a secondary heating role. The liquid guide parts 2 on two sides are designed to have certain resistance, so that the liquid guide parts have a heating function, the atomizing speed is increased, and the quick atomizing function of the electronic atomizing device is met. The heating part 1 in the middle is designed to have low resistance, the liquid guiding parts 2 on two sides are designed to have high resistance, the aim is to prevent the atomizing core from being burnt dry, and particularly when the local oil supply inside the liquid guiding parts 2 on two sides is insufficient, the design of the gradient resistor can effectively avoid the atomizing core from being burnt dry. If the resistance is designed to be uniform, dry burning is inevitable when the oil supply of the liquid guide portion 2 is locally insufficient.

Furthermore, the atomizing core can be a vertical atomizing core, the atomizing core is arranged in a vertical structure, and the heating part 1 can be regarded as an integrated heating plane; during atomization, the atomized liquid in the liquid guide part 2 can be atomized sufficiently, high reduction degree of the aroma of the atomized liquid can be realized, and contact between fresh atomized liquid and the heating part 1 can be reduced.

In order to further improve the energy utilization rate and completely remove the ineffective heating area, the oil guide piece 5 can be selected as liquid guide cotton, so that the atomization core and the cotton are in soft contact. At this moment, the atomizing core only needs to be fixed and need not consider sealedly, and the cotton serves as stock solution chamber 4 and plays stock solution and the sealed leak protection liquid function of lock liquid.
