Example 1

As shown in fig. 1, for the present invention, an atomizing core for an electronic atomizing device includes a heat generating portion 1, and the atomizing core further includes at least one liquid guiding portion 2 connected to the heat generating portion 1, and a plurality of liquid guiding grooves 20 having capillary force and arranged in parallel at intervals are formed on the surface of the liquid guiding portion 2. The number of the liquid guiding grooves 20 may be two or more, and is not particularly limited herein. Accordingly, the width of the fluid sink 20 may be between 50 microns and 1000 microns; the depth of the liquid guiding groove can be between 50 micrometers and 1000 micrometers, and the specific size of the liquid guiding groove 20 can be adjusted according to the set number and the actual situation, and is not limited in particular.

As shown in fig. 2, in one embodiment, at least one of the heat generating portion 1 and the liquid guiding portion 2 is a unitary structure, that is, the atomizing core is integrally sintered, the material of the heat generating portion 1 has a conductive function, and is made of a macroscopically uniform material, a microscopically single-phase conductive material, or a multi-phase conductive material formed by uniformly mixing multi-phase materials. Therefore, the conductive materials of the heating part 1 and the liquid guide part 2 can be selected from metal, metal glass, metal ceramic or conductive ceramic composite oxide, and the resistance value can be adjusted by regulating and controlling the content of each component. Of course, the heating part 1 and the liquid guiding part 2 can be connected by other processes, for example, the heating part 1 is the innermost layer, which can be a heating circuit or a whole plate surface heating; when the heating part 1 is compact and whole, it can be used as both heating body and supporter to provide mechanical strength support for atomizing core. One side or both sides of the heating portion 1 are liquid guiding portions 2, and the heating portion 1 and the liquid guiding portions 2 can be connected by adhesion or the like, and can be adjusted according to actual conditions, which is not limited herein.

As shown in fig. 3, the number of liquid guide portions 2 may be one, that is, only the liquid guide portion 2 on the heat generating portion 1 side may be included. In another embodiment, the number of the liquid guide parts 2 can be two, and double-sided atomization is adopted, so that the remarkable advantage of large atomization amount is achieved. Specifically, the liquid guiding part 2 includes a first liquid guiding part 21 and a second liquid guiding part 22 disposed on two opposite sides of the heat generating part 1 in the width direction, the liquid guiding grooves 20 are respectively disposed on the first liquid guiding part 21 and the second liquid guiding part 22 in parallel at intervals, that is, a plurality of liquid guiding grooves 20 with capillary force are formed on the surface of the first liquid guiding part 21 in parallel at intervals, and likewise, a plurality of liquid guiding grooves 20 with capillary force are also formed on the surface of the second liquid guiding part 22 in parallel at intervals, and the liquid guiding part 2 can simultaneously realize liquid guiding, liquid storing and atomizing functions.

Further, the shape of the liquid guiding portion 2 is preferably a square shape, but may be other shapes as necessary; it is understood that the shape and size of the heat generating part 1 and the liquid guiding part 2 may be the same, and are not limited herein. 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 aim is to improve the atomization speed and meet the rapid atomization function. The middle heating part 1 is designed to have high resistance, and the two side liquid guiding parts 2 are designed to have low resistance, so as to prevent the heating part 1 from being burnt; when the power supply is switched on, the heating part 1 in the middle has large resistance to play a main heating role, and the liquid guide parts 2 on the two sides have small resistance to play a secondary heating role; especially, when the local oil supply is insufficient in the liquid guide parts 2 at two sides, the design of the gradient resistor can effectively avoid the dry burning of the heating part 1. 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.

Further, the first electrode 41 and the second electrode 42 are respectively disposed on two opposite sides of the heat generating portion 1 in the longitudinal direction, and the heat generating portion 1 generates heat by conducting electricity between the first electrode 41 and the second electrode 42. The first electrode 41, the second electrode 42 and the liquid guiding groove 20 are arranged in parallel, in this embodiment, the electrodes are arranged on the end face of the heating part 1, so that the main heating part 1 of the atomizing core is positioned in the middle of the heating part 1, especially in the liquid guiding groove 20 which is symmetrically distributed on both sides, where the current path is narrowest and the heating value is largest. In addition, the heat generation area and the atomization area can be controlled by adjusting the setting height of the electrode. Understandably, the first electrode 41 and the second electrode 42 comprise a positive electrode and a negative electrode with opposite polarities, and if the first electrode 41 is the positive electrode, the second electrode 42 is the negative electrode; conversely, if the first electrode 41 is a negative electrode, the second electrode 42 is a positive 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 heat generating area, and the liquid guiding groove 20 with capillary force of the liquid guiding part 2 generates 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, the liquid guide grooves 20 of the first liquid guide part 21 and the liquid guide grooves 20 of the second liquid guide part 22 are symmetrically arranged. In some embodiments, the liquid guiding grooves 20 of the first liquid guiding portion 21 and the liquid guiding grooves 20 of the second liquid guiding portion 22 are arranged in staggered rows. Preferably, the atomization liquid is symmetrically arranged, so that when the atomization liquid generates heat, the atomization liquid is mainly positioned in a heating area in the middle of the heating part 1, the heat flow density is more concentrated, and the temperature rising rate is higher.

As shown in fig. 6, further, the atomizing core further includes a connecting portion 8 for fixing or sealing, the connecting portion 8 extends along the axial direction of the liquid guiding portion 2, and the connecting portion 8 is also formed with a liquid guiding groove 20 extending along the axial direction. The connection 8 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 as short as possible, that is, the height of the connection portion 8 should be smaller than the height of the liquid guide portion 2, and the height of the connection portion 8 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, the connecting portion 8 is further provided with the heat insulating groove 81, the heat insulating groove 81 crosses the plurality of liquid guide grooves 20, and both ends in the longitudinal direction thereof are positioned in the connecting portion 8, that is, the length of the heat insulating groove 81 is smaller than that of the connecting portion 8, and the heat insulating groove 81 does not penetrate in the transverse longitudinal direction of the connecting portion 8. Specifically, the setting width of the heat insulation groove 81 is less than or equal to 1 mm, so as to ensure that the atomized liquid in the liquid storage cavity 5 can be adsorbed to the liquid guide groove 20 by capillary force to complete atomization.

Further, the heat generating part 1 may be a compact structure, i.e., the heat generating part 1 may adopt a compact substrate. In other embodiments, the heat generating part 1 may be a porous structure with certain porosity and pore size, i.e. the heat generating part 1 may adopt a porous matrix, such as porous ceramic; specifically, the porosity of the porous matrix may be between 0 and 80%, with pore diameters in the range of 10 to 100 μm. The heat generating part 1 with the porous structure can reduce the overall heat capacity of the atomizing core, thereby improving the atomizing rate and the mist consumption ratio; the oil guide speed can be improved by matching with a plurality of liquid guide grooves 20 formed on the surface of the liquid guide part 2; and the heating part 1 adopts a porous structure, so that the heating part 1 positioned between the liquid guide grooves 20 can participate in atomization when liquid is atomized, and the atomization amount can be improved.

Further, the material of the heat generating portion 1 is metal, cermet, metallic glass, or conductive ceramic and composite oxide thereof. Further, the cermet is prepared by compounding at least one of metal or metal alloy and a ceramic material. Specifically, the ceramic material may include at least one of alumina, zirconia, silica, yttria, lanthana, ceria, and magnesia.

Further, this atomizing core is vertical type atomizing core, and a plurality of liquid guide grooves 20 all extend the setting from bottom to top along longitudinal direction. The atomizing core is arranged in a vertical structure, the liquid guiding grooves 20 on the liquid guiding parts 2 at two sides of the heating part 1 can be regarded as liquid storing channels, the liquid storing channels only store atomizing liquid required during atomization, and the heating part 1 can be regarded as an integrated heating plane. During atomization, the atomized liquid in the liquid guide groove 20 can be atomized sufficiently under ideal conditions, and high reduction degree of the aroma of the atomized liquid can be realized. The vertically arranged liquid guide groove 20 can greatly accelerate the oiling rate, so that atomized liquid can be supplied among all parts in time in the pumping process; in addition, the vertical liquid guide groove 20 enables the liquid guide part 2 to be in a semi-hollow state, so that the overall heat capacity of the atomizing core can be effectively reduced, and the atomizing efficiency is improved.
