[0023] Please refer to FIG. 1, which is a structural schematic diagram of one embodiment of a heating member according to the present application.

[0024] The heating element 100 includes a heat generating member 110 and an electrode portion 120 connected to the heat generating member 110. The heat generating member 110 includes a heat generating portion and a first fitting portion 1101, and the electrode portion 120 includes an electrode body 121 and a second fitting portion 1201, and both the first fitting portion 1101 and the second fitting portion 1201 are used for insertion into a liquid absorber provided in advance (see liquid absorber 200 described later for details).

[0025] In this embodiment, the heating member 100 may include two electrode portions 120, which are connected to opposite ends of the heat generating member 110 respectively.

[0026] The heat generating member 110 may be bent multiple times to form multiple first linear units 111 and multiple first recesses 1101, and two adjacent first linear units 111 may be connected via the first recesses 1101. The multiple first linear units 111 may constitute the heat generating portion of the heating member 100.

[0027] In this embodiment, the multiple first linear units 111 may all be arranged to be located within a first plane, the first fitting portions 1101 are all connected to opposite ends of the multiple first linear units 111, and the first fitting portions 110 at opposite ends of the first linear units 111 may be arranged to be located within a second plane and a third plane, respectively, and the second plane and the third plane both intersect with the first plane.

[0028] Furthermore, each first recess 1101 may further include at least one second linear unit 112 and a third linear unit 113. The multiple third linear units 113 are embedded in the liquid-absorbing material, that is, the sides of each third linear unit 113 are all covered by the liquid-absorbing porous ceramic material, and the ends are connected to the adjacent second linear units 112.

[0029] Or, in another embodiment, the heat generating member 110 may be bent multiple times to form a plurality of first linear units 111 and a plurality of second linear units 112. That is, the heat generating member 100 does not include a third linear unit 113. The first recess 1101 may include two second linear units 112, and one ends of the two second linear units 112 may be connected to each other to form an included angle, and the other ends of the two second linear units 112 are connected to the two first linear units 111, respectively.

[0030] In this embodiment, the electrode unit 120 further includes an electrode body 121, which is connected to the heat generating member 110 and is used to connect to a connecting wire, and the second fitting portion 1201 may be connected to the electrode body 121. In one embodiment, the second fitting portion 1201 and the electrode body 121 are integrally formed. The second fitting portion 1201 stably fixes the electrode body 121 to the liquid absorption, and prevents the electrode body 121 and the connecting wire from breaking or contact failure due to the loosening of the electrode body 121.

[0031] The first linear units 111 and the electrode bodies 121 of the two electrode units 120 may all be provided on a first plane, for example, the first linear units 111 and the electrode bodies 121 of the two electrode units 120 are all sheet-shaped, all provided on a first plane, and all parallel to the first plane. The third linear units 113 are provided in a fourth plane parallel to the first plane and spaced apart from each other. That is, the central connection lines of the first linear units 111 of the heat generating member 110 may all be provided in the first plane, and the central connection lines of the third linear units 113 of the heat generating member 110 may all be provided in the fourth plane, and the first plane and the fourth plane are parallel to each other and spaced apart from each other. The second linear units 112 of the heat generating member 110 can connect the first linear units 111 and the third linear units 113. Specifically, opposite ends of each second linear unit 112 may be connected to the first linear unit 111 and the third linear unit 113, respectively. The plurality of second linear units 112 located at one end of the first linear unit 111 may be provided to be positioned in a second plane, and the plurality of second linear units 112 located at the other end of the first linear unit 111 may be provided to be positioned in a third plane.

[0032] In this embodiment, the height of the first fitting portion 1101 may be equal or approximately equal to the length of the second linear unit 112, and the height of the first fitting portion 1101 may be 0.5 to 4 mm, and may be set, for example, to 0.5 mm, 1 mm, 2 mm, 3 mm, and 4 mm.

[0033] Furthermore, in this embodiment, when the heat generating member 110 is bent a plurality of first linear units 111, a plurality of second linear units 112, and a plurality of third linear units 113 by bending the heat generating member 110 a plurality of times, a bent portion can be formed between two connected linear units (the first linear unit 111, the second linear unit 112, or the third linear unit 113), and the bending angle of the bent portion can be 10° to 170°. For example, taking the connected first linear unit 111 and the second linear unit 112 as an example, the first linear unit 111 and the second linear unit 112 are both linear, and the connection portion of the first linear unit 111 and the second linear unit 112 can be a bent portion, and the bending angle of the bent portion can be 10° to 170°, and preferably, the bending angle of the bent portion can be 80° to 100°, and for example, the bending angle of the bent portion between the first linear unit 111 and the second linear unit 112 can be set to 80°, 90°, or 100°. In one preferred embodiment, the bend angle of the bend may be an obtuse angle.

[0034] The included angle between the first fitting portion 1101 and the first plane may be the same as the included angle between the first fitting portion 1101 and the first linear unit 111, or may be a supplementary angle. The included angle between the first fitting portion 1101 and the first linear unit 111 may be set to 90° to 170°, for example, 90°, 100°, 110°, 130°, or 170°. That is, the included angle between the first fitting portion 1101 and the first plane is indicated as 10° to 90°.

[0035] Furthermore, the included angle between the second fitting portion 1201 and the electrode body 121 may be the same as the bending angle of the bending portion between the second fitting portion 1201 and the electrode body 121, and the included angle between the second fitting portion 1201 and the electrode body 121 may similarly be an obtuse angle and may be set to 90° to 170°, that is, the included angle between the second fitting portion 1201 and the first plane may similarly be 10° to 90°.

[0036] In this embodiment, the included angle between the first fitting portion 1101 and the first plane may be set to be the same as the included angle between the second fitting portion 1201 and the first plane, and the first fitting portion 1101 and the second fitting portion 1201 located on the same side of the heat generating member 110 may be provided in the same plane, or may be provided in two parallel planes spaced apart from each other.

[0037] In other embodiments, the included angle between the first fitting portion 1101 and the first plane may be set to be different from the included angle between the second fitting portion 1201 and the first plane, i.e., the planes on which the first fitting portion 1101 and the second fitting portion 1201 are located intersect, and in this case, the stability of the heat-generating member 110 being fitted into the liquid absorbent can be further improved.

[0038] Alternatively, the second recess 1201 may be generally rectangular, square, triangular, or C-shaped.

[0039] Furthermore, in this embodiment, each electrode body 121 may be provided with a plurality of second fitting portions 1201, and the plurality of second fitting portions 1201 may be provided at different side ends of the electrode body 121 and connected to the edges of the electrode body 121.

[0040] In this embodiment, two second fitting portions 1201 are provided in each electrode body 121, and the two second fitting portions 1201 are provided on opposite sides of the electrode body 121. In another embodiment, the second fitting portion 1201 may be similarly connected to one edge of the electrode body 121 that is away from the heat generating member 110. Alternatively, at least two second fitting portions 1201 may be attached to each side edge (side edge not connected to the heat generating member 110) of the electrode body 121. Each second fitting portion 1201 may be provided with a through hole 1202.

[0041] In this embodiment, the heat generating member 110 and the electrode portion 120 may be integrally molded. For example, the heating member 100 may be manufactured from a metal sheet, and the heating member 100 as described above can be formed by pressing the metal sheet and then bending the same.

[0042] Alternatively, the heat generating member 110 and the electrode part 120 may be independent structures, and the two may be fixedly connected by a method such as welding, thereby forming the heating member 100.

[0043] The heat generating member 110 may be a metal strip or wire, and the cross-section of the heat generating member 110 may be any one of the shapes such as a circle, a square, a rectangle, an ellipse, etc., and in other embodiments, the cross-section of the heat generating member 110 may be a regular polygon such as a regular hexagon or a regular octagon.

[0044] Furthermore, in this embodiment, the heat generating member 110 may be a metal strip or wire, or may be a patterned metal sheet. The heat generating member 110 may be made of any one of metal alloys such as iron-chromium alloy, iron-chromium-aluminum alloy, iron-chromium-nickel alloy, chromium-nickel alloy, titanium alloy, stainless steel alloy, and Karma alloy, or may be made of a mixture of at least two of them.

[0045] When the heat generating member 110 is a metal strip or wire, the diameter of the cross section of the heat generating member 110 may be in the range of 0.02 mm to 1.00 mm, for example, 0.02 mm, 0.5 mm, or 1 mm. When the heat generating member 110 is a metal sheet, the heat generating member 110 may be a metal sheet having a thickness in the range of 0.01 mm to 2 mm.

[0046] When heat generating member 110 is bent to form a plurality of first linear units 111, a plurality of second linear units 112, and a plurality of third linear units 113, the length of each bent portion may be set within a range of 0.1 mm to 5 mm, for example, the length of each bent portion may be set to 0.1 mm, 2.5 mm, 5 mm, or the like.

[0047] As described in the above embodiment, the heat generating member 110 having a three-dimensional structure is formed by bending it multiple times, and in other embodiments, the heat generating member 110 having a three-dimensional structure may be obtained by one or more methods such as die pressing, casting, machine knitting, chemical etching, etc.

[0048] Alternatively, in another embodiment, the plurality of heat generating members 110 may be formed into a mesh structure by machine knitting, and then the formed mesh-like heat generating element may be subjected to a bending process to form a heat generating member 110 having a three-dimensional structure.

[0049] Alternatively, multiple sub-heat generating members having small diameters may be used and wound, glued, or welded to form a large diameter heat generating member 110. Next, the large diameter heat generating member 110 is bent to form a three-dimensional structure having multiple first linear units 111, multiple second linear units 112, and multiple third linear units 113.

[0050] 1, in this embodiment, the heat generating member 110 may be provided with a plurality of micro-holes 101, and the micro-holes 101 may be through-holes or blind holes provided in the heat generating member 110. By providing the micro-holes 101, it is possible to improve the bonding stability between the heat generating member 110 and the liquid absorbent, and the uniformity of heat conduction. Furthermore, by providing the micro-holes 101, it is possible to expose a part of the liquid absorbent, and the liquid to be heated can be infiltrated and discharged from the liquid absorbent through the surface exposed by the micro-holes 101, thereby more uniformly heating the liquid to be heated.

[0051] The number of micro-holes 101 may be multiple, and the multiple micro-holes 101 may be arranged at equal intervals in the longitudinal direction of the heat generating member 110. In this embodiment, the multiple micro-holes 101 may be arranged in the first linear unit 111, the second linear unit 112, or the third linear unit 113, and in other embodiments, the first linear unit 111, the second linear unit 112, and the third linear unit 113 may all have multiple micro-holes 101.

[0052] When the micro-holes 101 provided in the heat generating component 110 are through-holes, the through-holes may be circular holes, and the diameter of the through-holes may be set to 0.01 to 1.00 mm, for example, the diameter of the through-holes may be set to 0.01 mm, 0.5 mm, or 1 mm.

[0053] When the micro holes 101 provided in the heat generating member 110 are blind holes, the blind holes may be circular or rectangular. When the blind holes are circular, the diameter of the blind holes may be set to 0.01 to 1.00 mm, and when the blind holes are rectangular, the width of the blind holes may be set to 0.01 to 1.00 mm and the length may be set to 0.10 to 2.00 mm.

[0054] The distance between two adjacent micropores 101 may be set to 0.03 mm to 1.00 mm.

[0055] Therefore, in this embodiment, by providing multiple through holes in the heating unit of the heat-generating member 110, the bonding stability between the heat-generating member 110 and the liquid absorber can be further improved, and the heat generated by the heat-generating member 110 can be evenly diffused to the liquid absorber, thereby preventing the occurrence of heat accumulation due to poor contact between local areas of the heat-generating member 110 and the liquid absorber, which in turn prevents the occurrence of problems such as the local temperature of the heat-generating member 110 being too high, and at the same time ensuring that the liquid absorber can be heated quickly and evenly, thereby improving the atomization effect of the atomized liquid.

[0056] 2 to 4, FIG. 2 is a structural schematic diagram of one embodiment of the atomizing core according to the present application, FIG. 3 is an exploded view of the atomizing core shown in FIG. 2, and FIG. 4 is a structural schematic diagram of the atomizing core shown in FIG. 2 rotated 180°.

[0057] The atomizing core 20 includes a liquid absorber 200 and a heating member 100. The atomizing core 20 can be used to heat the atomized liquid, thereby atomizing the atomized liquid.

[0058] The liquid absorption 200 may be provided with a plurality of micropores or may have a plurality of micropores, thereby forming a porous body, through which the atomized liquid can enter the liquid absorption 200 through the micropores, or the atomized liquid can permeate from one side of the liquid absorption 200 to the other side through the micropores. The plurality of micropores in the liquid absorption 200 can further play a role of storage for the atomized liquid. The heating member 100 is partially embedded in the liquid absorption 200. The liquid absorption 200 includes an atomizing surface 201 and a liquid absorption surface 202. The liquid absorption surface 202 can contact the atomized liquid and allow the atomized liquid to enter the liquid absorption 200 from the surface. The atomized liquid in the liquid absorption 200 can be further transferred from one side of the liquid absorption surface 202 to one side of the atomizing surface 201, so that it can be heated and atomized on one side of the atomizing surface 201.

[0059] The material of the liquid absorber 200 may be a porous ceramic. Specifically, the material of the liquid absorber 200 is any one or more of aluminum oxide, silicon oxide, silicon nitride, silicate, and silicon carbide.

[0060] Specifically, first, a powder (or slurry) of a mixture of any one or more materials selected from aluminum oxide, silicon oxide, silicon nitride, silicate, and silicon carbide is used to form a raw material for the liquid-absorbing material 200, and then the heating member 100 is at least partially embedded in the preliminary raw material. The liquid-absorbing material 200 is then formed by heating and sintering, in which the heating member 100 is partially embedded, and the heating member 100 and the liquid-absorbing material 200 are brought into close contact with each other.

[0061] The shape and size of the liquid-absorbing member 200 are not limited and can be selected as needed.

[0062] In this embodiment, specifically, the liquid absorber 200 includes a bottom wall 210 and a side wall connected to one side of the bottom wall 210, the heating member 100 may be fitted into the liquid absorber 200, and the first fitting portion 1101 of the heating member 100 may be provided corresponding to the side wall, so that the atomized liquid close to one side of the side wall can be pre-heated by the first fitting portion 1101.

[0063] The side wall may be an annular side wall 220, which may be connected to one side of the bottom wall 210 and surround the bottom wall 210 to form a liquid collection groove 211. The first recess 1101 may pass through the bottom wall 210 and be partially inserted into the annular side wall 220.

[0064] The atomization surface 201 may be provided on the outer surface of the bottom wall 210, and the first recess 1101 and the second recess 1201 of the heating member 100 may be inserted into the liquid absorber 200 from one side of the atomization surface. Specifically, the first linear units 111 and the electrode body 121 of the heating member 100 are both inserted into the bottom wall 210. The first recess 1101 may penetrate the bottom wall 210 and be partially inserted into the annular side wall 220, and the second recess 1201 is accommodated in the bottom wall 210.

[0065] In this embodiment, by partially fitting the first fitting portion 1101 of the heating member 100 into the annular side wall 220, the atomized liquid on one side of the liquid-absorbing surface 202 can be preheated. When the viscosity of the atomized liquid is high, the atomized liquid can be preheated and its fluidity can be improved, so that the atomized liquid can be quickly introduced from the liquid-absorbing surface 202 into the liquid-absorbing 200, and the speed at which the atomized liquid in the liquid-absorbing 200 is transferred to the atomizing surface 201 can be improved, so that the atomized liquid on one side of the atomizing surface 201 can be promptly replenished, and the problem of dry combustion occurring in the atomizing core 100 can be avoided.

[0066] The outer surface of one side of the bottom wall 210 facing away from the annular side wall 220 is the atomization surface 201 of the liquid absorption 200, and the atomized liquid can be heated and atomized at the position of the atomization surface 201. The surface of the annular side wall 220 of the liquid absorption 200 facing away from the bottom wall 210 can contact the atomized liquid to form the liquid absorption surface 202, and the atomized liquid can enter the liquid absorption 200 from the liquid absorption surface, and can permeate out from the atomization surface 201 of the bottom wall 210. When the atomized liquid permeates out from the atomization surface 201, the part of the heating member 100 located outside the liquid absorption 200 can heat and atomize the atomized liquid that permeates out.

[0067] The opening of the liquid storage groove 211 is provided on one side of the annular side wall 220 away from the bottom wall 210, and the opening of the liquid storage groove 211 can put the atomized liquid into the liquid storage groove 211, and therefore the inner wall of the liquid storage groove 211 can also form the liquid absorbing surface of the liquid absorber 200.

The protrusion 212 can conduct the heat of the annular side wall 220 and / or the bottom wall 210 to the liquid to be atomized in the liquid storage groove 211 more quickly and more uniformly, and preheat the liquid to be atomized in the liquid storage groove 211, thereby further improving the atomization effect of the atomized liquid.

[0075] Alternatively, the number of the protrusions 212 may be at least two, and two adjacent protrusions 212 may be spaced apart to form a V-shaped groove or an arc-shaped groove.

[0076] With further reference to FIGS.

[0077] In this embodiment, the two electrode bodies 121 of the heating member 100 can respectively constitute the positive and negative poles of the heat generating member 110, and by electrically connecting the two electrode bodies 121 to the positive and negative poles of an external power source, power can be supplied to the heat generating element 210, thereby causing the heat generating element 210 to generate heat.

[0078] The second fitting portion 1201 may further be provided with a through groove 1202, and when the second fitting portion 1201 is embedded in the material of the liquid absorbent 200, the powder or slurry forming the liquid absorbent 200 can enter the through groove 1202, so that after the sintering fixation of the liquid absorbent 200 to the material is completed, the bonding stability between the heating member 100 and the liquid absorbent 200 can be further improved.

[0079] Further, referring to FIG. 6, in this embodiment, the thickness size L1 of the bottom wall 210 is 0.5 to 4 mm, the height L2 of the annular side wall 220 is 0.5 to 4 mm, and the thickness of the annular side wall 220 is greater than 0.8 mm; Furthermore, the present application further provides an atomizer.

[0080] The atomizer 30 includes an atomizing sleeve 310 , a mounting base 320 and an atomizing core 20 .

[0081] The atomizing sleeve 310 has a liquid storage cavity 312, and a ventilation tube 314 is provided inside the atomizing sleeve 310, the liquid storage cavity 312 is used for storing the atomized liquid, and the ventilation tube 314 is used for guiding the smoke to the user's mouth.

[0082] The mounting base 320 has a first pressure regulating passage 322, an injection cavity 321 and a smoke outlet 323. The first pressure regulating passage 322 is arranged around the injection cavity 321. The mounting base 320 is fitted into the atomizing sleeve 310. The first pressure regulating passage 322 and the injection cavity 321 are both connected to the storage cavity 312. The injection cavity 321 guides the atomized liquid to the atomizing core 20, which atomizes the atomized liquid to form smoke. The ventilation pipe 314 is connected to the smoke outlet 323 to guide the smoke to the user's mouth through the smoke outlet 323.

[0083] The atomizing core 20 is connected to one end opposite to the storage cavity 312 of the mounting base 320 and seals the injection cavity 321, thereby forming a storage space by the atomizing sleeve 310, the mounting base 320 and the atomizing core 20. After the atomized liquid is stored in the storage space, the atomized liquid seals the first pressure regulating passage 322.

[0084] When the balance between the air pressure in the liquid storage cavity 312 and the outside air pressure is lost due to a change in the external air pressure or suction, for example, when the air pressure in the liquid storage cavity 312 is too high, the atomized liquid may leak between the mounting base 320 and the inner wall of the atomizing sleeve 310, or the atomized liquid may leak from the atomizing core 20, or the atomized liquid may leak from the connection between the atomizing core 20 and the mounting base 320. Or, when the air pressure in the liquid storage cavity 312 is too low, the flow of the atomized liquid may not be smooth due to the influence of the pressure difference between the inside and outside of the liquid storage cavity 312, and the atomizing core 20 may not be supplied with enough liquid, which is likely to cause a burning smell during operation, bringing a bad suction experience to the user.

[0085] In addition, the present application further provides an electronic atomization device. Please refer to Fig. 12, which is a structural schematic diagram of an embodiment of the electronic atomization device of the present application.

A power supply assembly is provided in the main body assembly 410. When the atomizer 30 is attached to the main body assembly 410, the positive and negative poles of the power supply assembly in the main body assembly 410 are electrically connected to the two electrode bodies 121, respectively, to form a power supply circuit to supply power to the heat-generating member 110.

Furthermore, by embedding the first fitting part of the heating element in the annular side wall, the atomized liquid on one side of the liquid absorption surface can be preheated, and when the viscosity of the atomized liquid is high, the atomized liquid can be preheated and its fluidity can be improved, so that the atomized liquid can quickly enter the liquid absorption from the liquid absorption surface, and the speed at which the atomized liquid in the liquid absorption is transferred to the atomization surface can be improved, so that the atomized liquid on one side of the atomization surface can be timely replenished to avoid the problem of dry burning occurring in the atomization core.
