In an embodiment, the heat generating area 11d is formed by protruding at least a part of the second surface 11b, the heat generating area 11d includes heat generating surfaces 11e facing different directions, and the liquid guiding holes 11c are provided on the substrate 11, so that when the projection area of the heat generating surfaces 11e on the second surface 11b is fixed, the heat generating area 11d is formed by protruding at least a part of the second surface 11b, the heat generating area 11d includes heat generating surfaces 11e facing different directions, the total area of the heat generating surfaces 11e is increased, the distribution area of the aerosol generating substrate on the heat generating surfaces 11e is larger, the heat exchange area of the aerosol generating substrate can be increased, the atomization amount can be increased, the aerosol generating substrate can be heated more uniformly, the content of harmful substances generated by local high temperature of the aerosol generating substrate can be reduced, and the use experience can be effectively improved.

In one embodiment, the heating surfaces 11e are parallel to the corresponding liquid inlet surface 11g, so that the liquid inlet is kept uniform and stable, and the atomizing core 10 can heat the atomized aerosol generating substrate more uniformly.

The fact that the heat generating surface 11e is parallel to the corresponding liquid inlet surface 11g means that all points on the heat generating surface 11e are equal to the distance from the corresponding liquid inlet surface 11g, and the heat generating surface 11e and the corresponding liquid inlet surface 11g may be flat surfaces or curved surfaces.

The heat generating surface 11e is parallel to the corresponding liquid inlet surface 11g, and the liquid guide hole 11c is provided substantially perpendicular to the heat generating surface 11e and the liquid inlet surface 11g.

In an embodiment, the liquid guiding holes 11c are orderly arranged, on the one hand, compared with the holes arranged in disorder, the number of the orderly arranged liquid guiding holes 11c and the like can be designed and calculated, the guiding effect of the substrate 11 on the aerosol generating substrate is more controllable, and the production consistency of the product can be improved, in other words, in the mass production, the liquid guiding holes 11c of different substrates 11 are basically consistent, so that the heating effect of the heating bodies 12 delivered from the same batch tends to be consistent.

The disordered arrangement refers to random generation of holes, and no rule is set. The ordered arrangement means that the plurality of liquid guiding holes 11c are arranged according to a set rule. Ordered arrangements include, but are not limited to, array arrangements. For example, in one embodiment, the array arrangement may be a one-dimensional array arrangement of the plurality of liquid guiding holes 11c, that is, the plurality of liquid guiding holes 11c are arranged at intervals in one direction.

For example, the heat generating film is aluminum, gold, silver, copper, nichrome, iron-chromium-aluminum alloy, nickel, platinum, or titanium, or the like.

The resistance value of the heat generating film may be set according to the need, and in this application, the resistance value of the heat generating film is between 0.2Ω (ohm) and 0.8Ω, for example. Therefore, the heating film can be heated up quickly and can be matched with the power supply assembly well.

In one embodiment, referring to fig. 3 and 4, the heating surfaces 11e are symmetrically disposed along the center of the base 11. In this way, the atomizing core 10 can heat the atomized aerosol generating substrate more uniformly, and in addition, the heating surfaces 11e are symmetrically arranged along the center of the substrate 11, so that the heating surfaces 11e and the liquid inlet surface 11g of the atomizing core 10 are arranged at equal intervals, and the uniformity and stability of liquid inlet are further maintained.

In one embodiment, referring to fig. 1 to 4, a groove 11f is formed in at least a portion of the first surface 11a, and the liquid inlet 11g is disposed on a wall surface of the groove 11 f. On the one hand, the grooves 11f can temporarily store aerosol-generating substrates, so that not only can a large amount of aerosol-generating substrates from the liquid storage cavity 100a be reduced to directly impact the atomizing core 10 to play a role in slow flow, but also the pre-stored aerosol-generating substrates can be played, and the flow guiding area can be increased so as to be timely supplemented to the heating surface 11e.

In an embodiment, please continue to refer to fig. 1 to 4, the outline shape of the heating area is a triangular prism shape, and at least two sides of the triangular prism are heating surfaces 11e. That is, the liquid guiding holes 11c on at least two heating surfaces 11e face different directions, that is, the atomizing core 10 has different oriented atomizing angles, so that the atomized aerosol can be sprayed in different directions, and the opposite impact of the aerosol with the air flow flowing from the outside can be reduced to a certain extent.

In an embodiment, referring to fig. 1 to 4, the heat generating region 11d includes two heat generating surfaces 11e, and the distance between the two heat generating surfaces 11e gradually decreases with distance from the second surface 11 b. That is, the two heating surfaces 11e gradually approach each other along with being far away from the second surface 11b, so that the liquid guiding holes 11c are beneficial to being arranged towards the direction approximately perpendicular to the heating surfaces 11e, that is, when the substrate 11 is horizontally placed and the heating area 11d faces downwards, both atomization angles of the atomization core 10 face to two sides, so that atomized aerosol can be reduced to be directly sprayed downwards, the opposite impact of the aerosol and air flow flowing in from the outside can be reduced to a certain extent, the air flow flowing in from the outside can be more beneficial to carrying the aerosol atomized from different atomization angles out, and the smoke quantity is improved.

In one embodiment, referring to fig. 1 to 4, two heating surfaces 11e intersect at an end far from the second surface 11 b. That is, the heat generating region 11d is a triangular prism, at least two sides of the triangular prism are heat generating surfaces 11e, the atomization core 10 increases the total heat generating area, and the opposite impact of aerosol with the air flow flowing in from the outside can be reduced to some extent.

In one embodiment, the outline shape of the heat generating region 11d is cylindrical, and at least part of the outer side surface of the cylindrical shape is the heat generating surface 11e. The column shape includes but is not limited to cuboid, square, cylinder etc., and this application is exemplified by the cuboid, and the heating area 11d of cuboid has four lateral surfaces, a bottom surface and a top surface, and when the bottom surface overlaps with the second surface 11b, part or all in four lateral surfaces and the top surface of cuboid can all be regarded as heating surface 11e, not only can reduce the design degree of difficulty of heating surface 11e, can also show the total area that increases heating surface 11e, show the promotion atomizing volume. The outline shape of the heat generating region 11d refers to the outline shape of the heat generating region 11d in a multidimensional space.

It should be noted that, the top surface of the cuboid may be rounded or designed to be a cambered surface and smoothly connected to the side surface, so as to further increase the total area of the heat generating surface 11e.

In one embodiment, the heating surface 11e is a curved surface, and the curvature of the curved surface is not zero, so that the ratio of the curved heating surface 11e to the radiating surface is relatively large relative to the planar heating body 12, which improves the heat utilization rate, and the radiating surface corresponds to the liquid inlet surface 11g. In addition, the curved heating surface 11e has a wider atomization angle, so when the heating area 11d faces downwards, the atomized aerosol is reduced to be directly sprayed downwards, so that the opposite impact of the aerosol and the air flow flowing in from the outside can be reduced to a certain extent, the air flow flowing in from the outside is more favorable for bringing the aerosol atomized from different atomization angles out, and the smoke quantity is further improved.

Illustratively, the outline shape of the heat generating region 11d is spherical, and the heat generating surface 11e constitutes at least a partial spherical surface. Therefore, the ratio of the heating surface 11e to the radiating surface is relatively large, the heat utilization rate is improved, and the atomization amount is improved.

In one embodiment, the outline shape of the heat generating region 11d is a paraboloid, hyperboloid or ellipsoid. The heating areas 11d with the shapes can be arranged as the curved heating surfaces 11e on the outer side surfaces, so that the ratio of the curved heating surfaces 11e to the radiating surfaces is relatively large, the heat utilization rate is improved, the smoke quantity is improved, and a good atomization effect is achieved.

It will be appreciated that too small a pore size of the liquid guiding hole 11c can reduce the liquid feeding rate but limit the liquid feeding rate, while too large a pore size of the liquid guiding hole 11c can increase the liquid feeding rate but also risk liquid leakage, so that in one embodiment, the pore size of the liquid guiding hole 11c is 20 μm-100 μm, i.e. the pore size of the liquid guiding hole 11c is between 20 μm-100 μm. Exemplary liquid-conducting apertures 11c have a pore size of 20 μm, 21 μm, 22 μm, 25 μm, 30 μm, 35 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 85 μm, 90 μm, 97 μm or 100 μm, etc. Thus, the aperture of the liquid guide hole 11c is moderate, so that the liquid supply efficiency is high, and the risk of liquid leakage can be avoided.

It will be appreciated that although the porosity of the heat-generating surface 11e is too large to increase the liquid supply amount, the structural strength of the substrate 11 is poor, and the porosity of the heat-generating surface 11e is too small to increase the structural strength but has the problem of insufficient liquid supply amount, and in this embodiment, referring to the figure, the porosity of the heat-generating surface 11e is 20% -50%, that is, the porosity of the heat-generating surface 11e is between 20% -50%. Illustratively, the heating surface 11e has a porosity of 20%, 20.5%, 21%, 22%, 25%, 30%, 35%, 40%, 45%, 50%, or the like. In this way, the porosity of the heat generating surface 11e is moderate, so that not only can the liquid supply amount be ensured to be large, but also the structural strength of the substrate 11 can be ensured to be large.

It will be appreciated that too long a length of the liquid guiding hole 11c may easily result in slower liquid supply, while too short a length of the liquid guiding hole 11c may easily leak liquid, and thus, in one embodiment, referring to the drawings, the length of the liquid guiding hole 11c is between 0.1mm and 10mm. Exemplary liquid transfer apertures 11c are 0.1mm, 0.15mm, 0.2mm, 0.5mm, 1.0mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm, 7.0mm, 8.0mm, 8.5mm, 8.7mm, 9.0mm, 10.0mm, etc. Thus, the length of the liquid guide hole 11c is moderate, so that the liquid substrate from the liquid inlet surface 11g can flow to the heating surface 11e in time, and the risk of liquid leakage can be avoided.

In one embodiment, referring to fig. 5, the air outlet channels 110a and the heat generating surface 11e are disposed obliquely, i.e. the air outlet channels 110a are not perpendicular to the heat generating surface 11e. Therefore, the air flow flowing in from the outside is beneficial to bringing the aerosol atomized from different atomization angles out, and the smoke quantity is further improved.

In an embodiment, referring to fig. 5, the electronic atomization device includes an air inlet channel 110b communicating with the outside, and an air flow from the outside can enter the atomization cavity 120a through the air inlet channel 110b, wherein the air inlet channel 110b is inclined to the heating surface 11e, i.e. the air inlet channel 110b is not perpendicular to the heating surface 11e. The air inlet channel 110b extends along the axial direction of the electronic atomizing device, that is, the external airflow flows into the atomizing cavity 120a along the axial direction, so that when the heating area 11d faces downwards, the liquid guide holes 11c with different orientations on the heating surface 11e are not sprayed towards the air inlet channel 110b, but are sprayed towards the side surface of the air inlet channel 110b, so that atomized aerosol is favorably reduced to be directly sprayed downwards, the offset of the aerosol with the airflow flowing in from the outside can be reduced to a certain extent, the airflow flowing in from the outside is favorably brought out of the aerosol atomized from different atomizing angles, and the smoke quantity is further improved.

In this way, the aerosol in the atomization cavity 120a enters the air guide channel 120b through the air vent 120e, and then enters the air outlet channel 110a through the open end 120c of the atomization cavity 120a, so that not only is the space effectively utilized, but also the use by users is facilitated.

Referring to fig. 5, the housing 110 and the atomizing base 120 together form an air inlet channel 110b, an air outlet channel 110a is connected to the top end of the atomizing chamber 120a, and the air inlet channel 110b is connected to the bottom end of the atomizing chamber 120 a. That is, the inlet passage 110b is located at the bottom side of the atomizing chamber 120a, and the outlet passage 110a is located at the top side of the atomizing chamber 120 a. Alternatively, one end of the air outlet passage 110a communicates with the open end 120c of the air guide passage 120b shown in some of the foregoing embodiments, and the other end of the air outlet passage 110a communicates with the suction nozzle to perform the suction process.

In one embodiment, the number of the liquid inlet channels is plural. Illustratively, the number of feed channels is 2. Thus, the aerosol generating substrate in the liquid storage cavity 100a is conveniently conveyed to the atomization core 10 through the liquid inlet channels for heating and atomization, so that atomization efficiency is improved, and the situation that liquid absorption of the atomization core 10 is blocked due to blockage of any one liquid inlet channel can be avoided, so that dry combustion of the atomization core 10 is caused.

Each liquid inlet channel is symmetrically distributed along the central axis of the air outlet channel 110a, so that the interference of the liquid discharging among the liquid inlet channels can be avoided, and the smoothness of the liquid discharging can be improved.
