Electronic atomization devices generally have an atomization core, and the atomization core includes an aspirating liquid and a heating element. The aspirating liquid can be connected to the liquid storage space of the atomized liquid, so that the atomized liquid in the liquid storage space can penetrate out from the side of the aspirating liquid.

[0042] The heating body 100 includes a heating element 110 and an electrode portion 120 connected to the heating element 110. The heating element 110 includes a heating portion and a first embedded portion 1101; the electrode portion 120 includes an electrode body 121 and a second embedded portion 1201; the first embedded portion 1101 and the second embedded portion 1201 are both used to be inserted into a preset liquid absorbing liquid (for details, refer to the liquid absorbing liquid 200 described later).

[0043] In this embodiment, the heating element 100 may include two electrode portions 120 , and the two electrode portions 120 are respectively connected to opposite ends of the heating element 110 .

[0044] The heating element 110 may be bent multiple times to form multiple first linear units 111 and multiple first embedded parts 1101, and two adjacent first linear units 111 may be connected via the first embedded parts 1101. The multiple first linear units 111 may constitute the heating part of the heating element 100.

[0047] Alternatively, in other embodiments, the heating element 110 may be bent multiple times to form multiple first linear units 111 and multiple second linear units 112. That is, the heating element 100 does not include the third linear unit 113. The first embedded portion 1101 may include two second linear units 112, wherein one end of each of the two second linear units 112 may be connected to each other at an angle, and the other end of each of the two second linear units 112 is connected to the two first linear units 111, respectively.

[0048] In this embodiment, the electrode part 120 further includes an electrode body 121, the electrode body 121 is connected to the heating element 110 and is used to connect to the connecting wire, and the second embedded part 1201 can be connected to the electrode body 121. In one embodiment, the second embedded part 1201 is integrally formed with the electrode body 121. The second embedded part 1201 can stably fix the electrode body 121 on the absorbent liquid, avoiding the problem of breakage or poor contact between the electrode body 121 and the connecting wire due to the loosening of the electrode body 121.

[0049] Among them, the plurality of first linear units 111 and the electrode bodies 121 in the two electrode parts 120 can all be arranged on the first plane. For example, the plurality of first linear units 111 and the electrode bodies 121 in the two electrode parts 120 are all sheet-shaped, all arranged on the first plane and all parallel to the first plane. The plurality of third linear units 113 are arranged in a fourth plane that is parallel to the first plane and arranged at intervals. That is, the center lines of the plurality of first linear units 111 in the heating element 110 can all be arranged in the first plane; the center lines of the plurality of third linear units 113 in the heating element 110 can all be arranged in the fourth plane, and the first plane and the fourth plane are parallel and arranged at intervals. The plurality of second linear units 112 in the heating element 110 can connect the plurality of first linear units 111 and the plurality of third linear units 113. Specifically, the opposite ends of each second linear unit 112 can 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 arranged to be located in the second plane, and the plurality of second linear units 112 located at the other end of the first linear unit 111 may be arranged to be located in the third plane.

[0050] In this embodiment, the height of the first embedded portion 1101 may be equal to or approximately equal to the length of the second linear unit 112, wherein the height of the first embedded portion 1101 may be 0.5-4 mm, for example, may be set to 0.5 mm, 1 mm, 2 mm, 3 mm and 4 mm.

[0051] Further, in this embodiment, when the heating element 110 is bent multiple times to form a plurality of first linear units 111, a plurality of second linear units 112, and a plurality of third linear units 113, a bending portion may 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 bending portion is 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 between the first linear unit 111 and the second linear unit 112 may be a bending portion, and the bending angle of the bending portion may be 10° to 170°, wherein the bending angle of the bending portion may preferably be 80° to 100°, for example, the bending angle of the bending portion between the first linear unit 111 and the second linear unit 112 may be set to 80°, 90°, or 100°. In a preferred embodiment, the bending angle of the bending portion may be an obtuse angle.

[0052] The angle between the first embedded portion 1101 and the first plane may be the same as or complementary to the angle between the first embedded portion 1101 and the first linear unit 111. The angle between the first embedded 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 angle between the first embedded portion 1101 and the first plane is 10° to 90°.

[0053] Furthermore, the angle between the second embedded portion 1201 and the electrode body 121 can be the same as the bending angle of the bending portion between the second embedded portion 1201 and the electrode body 121, wherein the angle between the second embedded portion 1201 and the electrode body 121 can also be an obtuse angle and can be set to 90°~170°, that is, the angle between the second embedded portion 1201 and the first plane can also be 10°~90°.

[0054] In this embodiment, the angle between the first embedded portion 1101 and the first plane and the angle between the second embedded portion 1201 and the first plane can be set to be the same, and the first embedded portion 1101 and the second embedded portion 1201 located on the same side of the heating element 110 can be set in the same plane or respectively set in two parallel and spaced planes.

[0055] In other embodiments, the angle between the first embedded portion 1101 and the first plane and the angle between the second embedded portion 1201 and the first plane can also be set to be different, that is, the planes where the first embedded portion 1101 and the second embedded portion 1201 are located intersect, at this time, the stability of the heating element 110 embedded in the liquid absorbent can be further improved.

[0056] Optionally, the second embedded portion 1201 may be rectangular, square, triangular or I-shaped as a whole.

[0057] Furthermore, in this embodiment, a plurality of second embedded portions 1201 may be disposed on each electrode body 121 , wherein the plurality of second embedded portions 1201 may be respectively disposed at different side ends of the electrode body 121 and connected to the edge of the electrode body 121 .

[0058] In this embodiment, two second embedded parts 1201 are provided on each electrode body 121, and the two second embedded parts 1201 are respectively provided on opposite sides of the electrode body 121. In other embodiments, the second embedded part 1201 can also be connected to the edge of one side of the electrode body 121 away from the heating element 110. Optionally, at least two second embedded parts 1201 can be installed on each side of the electrode body 121 (the side not connected to the heating element 110). Among them, each second embedded part 1201 can be provided with a through hole 1202.

[0059] In this embodiment, the heating element 110 and the electrode part 120 can also be integrally formed. For example, the heating element 100 can be made of a metal sheet, and the metal sheet is stamped and then bent to form the heating element 100 as described above.

[0060] Alternatively, the heating element 110 and the electrode portion 120 may be independent structures, and the two may be fixedly connected by welding or the like to form the heating element 100 .

[0061] Among them, the heating element 110 can be a metal strip or a metal wire, and the cross-section of the heating element 110 can be any one of circular, square, rectangular, elliptical and other shapes. In other embodiments, the cross-section of the heating element 110 can also be a regular polygon such as a regular hexagon or a regular octagon.

[0062] Furthermore, in this embodiment, the heating element 110 can be a metal strip or a metal wire, or can also be a patterned metal sheet. The heating element 110 can 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 kama alloy, or can also be made of a mixture of at least two of them.

[0063] When the heating element 110 is a metal strip or a metal wire, the diameter of the cross section of the heating element 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 heating element 110 is a metal sheet, the heating element 110 may be a metal sheet with a thickness in the range of 0.01 mm to 2 mm.

[0064] When the heating element 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 can be set within the range of 0.1 mm to 5 mm. For example, the length of each bent portion can be set to 0.1 mm, 2.5 mm or 5 mm, etc.

[0065] As described in the above embodiments, the heating element 110 with a three-dimensional structure is formed by multiple bending. In other embodiments, the heating element 110 with a three-dimensional structure can also be obtained by one or more methods such as mold stamping, casting, mechanical weaving, chemical etching, etc.

[0066] Alternatively, in other embodiments, a plurality of heating elements 110 may be mechanically woven into a mesh structure, and then the formed mesh heating element is bent to form a heating element 110 having a three-dimensional structure.

[0067] Alternatively, multiple sub-heating elements with smaller diameters may be used to form a larger diameter heating element 110 by winding, bonding or welding. Then, the larger diameter heating element 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.

[0068] Please refer to further Figure 1 In this embodiment, a plurality of micropores 101 may be provided on the heating element 110, wherein the micropores 101 may be through holes or blind holes provided on the heating element 110. The stability of the combination between the heating element 110 and the absorbent liquid and the uniformity of heat conduction may be improved by providing the micropores 101. Furthermore, the micropores 101 may expose part of the absorbent liquid, so that the liquid to be heated may penetrate from the surface of the absorbent liquid exposed through the micropores 101, so as to better uniformly heat the liquid to be heated.

[0069] There may be a plurality of micropores 101, and the plurality of micropores 101 may be arranged in sequence at equal intervals along the length direction of the heating element 110. In this embodiment, the plurality of micropores 101 may be arranged on the first linear unit 111, the second linear unit 112, or the third linear unit 113; in other embodiments, the plurality of micropores 101 may be arranged on the first linear unit 111, the second linear unit 112, and the third linear unit 113.

[0070] When the microhole 101 formed on the heating element 110 is a through hole, the through hole may be a circular hole, and the diameter of the through hole may be set to 0.01-1.00 mm, for example, the diameter of the through hole may be set to 0.01 mm, 0.5 mm or 1 mm.

[0071] When the microhole 101 opened on the heating element 110 is a blind hole, the blind hole can be a circular hole or a rectangular hole; when the blind hole is a circular hole, the diameter of the blind hole can be set to 0.01-1.00 mm, and when the blind hole is a rectangular hole, the width of the blind hole can be set to 0.01-1.00 mm, and the length can be set to 0.10-2.00 mm.

[0072] The distance between two adjacent microholes 101 may be set to be 0.03 mm to 1.00 mm.

[0073] Therefore, in the present embodiment, a plurality of through holes are provided on the heating unit of the heating element 110, so that the stability of the combination between the heating element 110 and the liquid absorbing material can be further improved, so that the heat emitted by the heating element 110 can be evenly diffused into the liquid absorbing material, thereby preventing the problem of excessively high local temperature of the heating element 110 caused by heat accumulation in a local area of ​​the heating element 110 due to poor contact with the liquid absorbing material, and at the same time, ensuring that the liquid absorbing material can be heated up quickly and evenly, thereby improving the atomization effect of the atomized liquid.

[0074] See also Figure 2-Figure 4 , Figure 2 It is a structural schematic diagram of an embodiment of the atomizer core provided by the present application; Figure 3 yes Figure 2 An exploded view of the atomizer core shown; Figure 4 yes Figure 2 The schematic diagram of the structure of the atomizer core after rotating 180° is shown.

[0075] The atomizing core 20 includes a liquid absorbing agent 200 and a heating element 100. The atomizing core 20 can be used to heat the atomizing liquid, thereby atomizing the atomizing liquid.

[0076] The absorbing liquid 200 may be provided with a plurality of tiny holes to form a porous body, and the atomized liquid may enter the absorbing liquid 200 through the tiny holes, or the atomized liquid may penetrate from one side of the absorbing liquid 200 to the other side through the tiny holes. Among them, the plurality of tiny holes in the absorbing liquid 200 may also play a storage role for the atomized liquid. The heating element 100 is partially buried in the absorbing liquid 200. The absorbing liquid 200 includes an atomizing surface 201 and a absorbing liquid surface 202. The absorbing liquid surface 202 may contact with the atomized liquid so that the atomized liquid enters the absorbing liquid 200 from the surface. The atomized liquid in the absorbing liquid 200 may be further transferred from the absorbing liquid surface 202 side to the atomizing surface 201 side, so that it may be heated and atomized on the atomizing surface 201 side.

[0077] The material of the absorbent liquid 200 may be porous ceramics. Specifically, the material of the absorbent liquid 200 is any one or more of aluminum oxide, silicon oxide, silicon nitride, silicate and silicon carbide.

[0078] Specifically, a powder material (or slurry) of a mixture of any one or more materials selected from aluminum oxide, silicon oxide, silicon nitride, silicate and silicon carbide can be used to form a blank of the absorbent liquid 200, and then the heating element 100 can be at least partially buried in the pre-blank. By heating and sintering, the absorbent liquid 200 partially burying the heating element 100 can be formed, and the heating element 100 and the absorbent liquid 200 can be tightly combined.

[0079] The shape and size of the liquid absorbent 200 are not limited and can be selected as needed.

[0080] In this embodiment, specifically, the liquid absorbing body 200 includes a bottom wall 210 and a side wall connected to one side of the bottom wall 210, the heating element 100 can be embedded in the liquid absorbing body 200, and the first embedded portion 1101 of the heating element 100 can be arranged corresponding to the side wall, so that the atomized liquid close to the side of the side wall can be preheated through the first embedded portion 1101.

[0081] 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 storage tank 211 . The first embedded portion 1101 may pass through the bottom wall 210 and be partially inserted into the annular side wall 220 .

[0082] The atomizing surface 201 can be arranged on the outer surface of the bottom wall 210, and the first embedded portion 1101 and the second embedded portion 1201 of the heating element 100 can be inserted into the liquid absorbing liquid 200 from the side of the atomizing surface. Specifically, the plurality of first linear units 111 and the electrode body 121 of the heating element 100 are all embedded in the bottom wall 210. The first embedded portion 1101 can pass through the bottom wall 210 and be partially inserted into the annular side wall 220, and the second embedded portion 1201 is all accommodated in the bottom wall 210.

[0083] In this embodiment, by partially embedding the first embedded portion 1101 of the heating element 100 into the annular side wall 220, the atomized liquid on one side of the liquid absorption surface 202 can be preheated. When the viscosity of the atomized liquid is high, the atomized liquid can be preheated to improve its fluidity, so that the atomized liquid can enter the absorption liquid 200 from the absorption liquid surface 202 more quickly, and the transmission rate of the atomized liquid in the absorption liquid 200 to the atomizing surface 201 can be increased, so that the atomized liquid on one side of the atomizing surface 201 can be replenished in time to avoid the problem of dry burning of the atomizing core 100.

[0084] The outer surface of the bottom wall 210 on the side away from the annular side wall 220 is the atomization surface 201 of the absorbing liquid 200, and the atomized liquid can be heated and atomized at the position of the atomization surface 201. The side of the annular side wall 220 of the absorbing liquid 200 away from the bottom wall 210 can contact with the atomized liquid to form a liquid absorbing surface 202, so that the atomized liquid can enter the absorbing liquid 200 from the liquid absorbing surface, and can penetrate from the atomization surface 201 of the bottom wall 210. When the atomized liquid penetrates from the atomization surface 201, the portion of the heating element 100 located outside the absorbing liquid 200 can heat and atomize the penetrated atomized liquid.

[0085] The opening of the liquid storage tank 211 is arranged on the side of the annular side wall 220 away from the bottom wall 210, and the opening of the liquid storage tank 211 can allow the atomized liquid to enter the liquid storage tank 211. Therefore, the inner wall of the liquid storage tank 211 can also constitute the liquid absorption surface of the liquid absorption liquid 200. By providing the liquid storage tank 211, the area of ​​the liquid absorption surface 202 can be increased, thereby increasing the contact area between the atomized liquid and the liquid absorption liquid 200, and further facilitating the atomized liquid to penetrate into the liquid absorption liquid 200.

[0087] The outer contour of the annular side wall 220 can be roughly rectangular, and the first embedded parts 1101 on opposite sides of the heating element 100 can be respectively inserted into the partial side walls corresponding to the two opposite long sides of the annular side wall 220. The first embedded parts 1101 can be embedded in the partial side walls corresponding to the two opposite long sides of the annular side wall 220.

[0088] In this embodiment, by burying the heating element 100 in the absorbing liquid 200, the heating element 100 can be closely fitted with the absorbing liquid 200, thereby improving the uniformity of heat conduction of the heating element 100; at the same time, by burying the heating element 100 in the absorbing liquid 200, in the process of the atomized liquid permeating from the absorbing liquid surface to the atomizing surface, the heating element 100 can also preheat the atomized liquid in the absorbing liquid 200, thereby making the temperature of the atomized liquid uniformly increased, thereby improving the atomization effect of the atomized liquid. Among them, by inserting the first embedded portion 1101 of the heating element 110 into the annular side wall 220, the liquid to be atomized in the liquid storage tank 211 can also be preheated, thereby further improving the atomization effect of the atomized liquid.

[0089] In this embodiment, further, the atomization effect of the atomized liquid can be further improved by configuring the heating element 100 as a three-dimensional structure.

[0090] Further, such as Figure 6 The heating element 100 is shown buried in the liquid absorbing body 200. Specifically, the exposed surfaces of the plurality of first linear units 111 and the electrode body 121 may be flush with the outer surface of the bottom wall 210.

[0091] Alternatively, see Figure 8 In other embodiments, the heating element 100 may also be disposed partially beyond the outer surface of the bottom wall 210 .

[0092] In this embodiment, a protrusion 212 is further provided on the inner surface of the bottom wall 210, and the protrusion 212 can be connected to the annular side wall 220. Among them, the protrusion 212 can be arranged parallel to the short side of the annular side wall 220, and the opposite sides of the protrusion 212 can be respectively connected to the partial side walls corresponding to the two opposite long sides of the annular side wall 220. By providing the protrusion 212, the protrusion 212 can be immersed in the liquid to be atomized in the liquid storage tank 211. The protrusion 212 can transfer the heat of the annular side wall 220 and / or the bottom wall 210 to the liquid to be atomized in the liquid storage tank 211 faster and more evenly, preheat the liquid to be atomized in the liquid storage tank 211, thereby further improving the atomization effect of the atomized liquid.

[0093] Optionally, 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.

[0094] Please refer to further Figure 1 and Figure 2 .

[0095] In this embodiment, the two electrode bodies 121 of the heating element 100 can respectively constitute the positive and negative electrodes of the heating element 110. By electrically connecting the two electrode bodies 121 to the positive and negative electrodes of an external power source, the heating element 210 can be powered, thereby causing the heating element 210 to generate heat.

[0096] Among them, a through groove 1202 can also be set on the second embedded part 1201. When the second embedded part 1201 is buried in the blank of the absorbent liquid 200, the powder material or slurry that forms the absorbent liquid 200 can enter the through groove 1202. After the sintering and fixing of the blank of the absorbent liquid 200 is completed, the combination stability of the heating element 100 and the absorbent liquid 200 can be further improved.

[0097] For further information, please refer to Figure 6In this embodiment, the thickness L1 of the bottom wall 210 is 0.5-4 mm; the height L2 of the annular side wall 220 is 0.5-4 mm, and the wall thickness of the annular side wall 220 is greater than 0.8 mm;

[0098] Furthermore, the present application also provides an atomizer. Figure 9-11 . Fig. 9 It is a structural schematic diagram of an embodiment of an atomizer provided by the present application; Fig.10 yes Fig. 9 A cross-sectional view of the atomizer shown; Fig.11 yes Fig.10 A partial enlarged view of the atomizer in area II is shown.

[0099] The atomizer 30 includes an atomizing sleeve 310 , a mounting seat 320 and an atomizing core 20 .

[0100] The atomizing sleeve 310 has a liquid storage chamber 312 , and a ventilation tube 314 is arranged inside the atomizing sleeve 310 . The liquid storage chamber 312 is used to store the atomizing liquid, and the ventilation tube 314 is used to guide the smoke to the user's mouth.

[0101] The mounting seat 320 has a first pressure regulating channel 322, a liquid inlet chamber 321 and a smoke outlet 323. The first pressure regulating channel 322 is arranged in a circuitous manner on the peripheral side of the liquid inlet chamber 321. The mounting seat 320 is embedded in the atomizing sleeve 310, and the first pressure regulating channel 322 and the liquid inlet chamber 321 are both connected to the liquid storage chamber 312. The liquid inlet chamber 321 guides the atomized liquid to the atomizing core 20 so that the atomizing core 20 can atomize 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.

[0102] The atomizer core 20 is connected to one end of the mounting seat 320 away from the liquid storage chamber 312 and blocks the liquid chamber 321 , so that a liquid storage space is formed by the atomizer sleeve 310 , the mounting seat 320 and the atomizer core 20 . After the atomized liquid is stored in the liquid storage space, the atomized liquid seals the first pressure regulating channel 322 .

[0103] When the external air pressure changes or suction causes the air pressure in the liquid storage chamber 312 to lose balance with the external air pressure, for example, when the air pressure in the liquid storage chamber 312 is too high, the atomized liquid may leak from between the mounting seat 320 and the inner wall of the atomizing sleeve 310, or leak from the atomizing core 20, or leak from the connection between the atomizing core 20 and the mounting seat 320. Alternatively, when the air pressure in the liquid storage chamber 312 is too low, the atomized liquid may not flow smoothly due to the pressure difference between the inside and outside of the liquid storage chamber 312, and the atomizing core 20 may easily cause a burning smell during operation due to insufficient liquid supply, which brings a bad suction experience to the user.

[0104] Furthermore, the present application also provides an electronic atomization device. Fig.12 , FIG12 is a schematic structural diagram of an embodiment of an electronic atomization device provided in the present application.

[0105] The electronic atomization device 40 includes an atomizer 30 and a main body component 410. The atomizer 30 can be used to store atomized liquid and atomize the atomized liquid to form smoke that can be inhaled by the user. The atomizer 30 can be installed on the main body component 410. A power supply component is arranged in the main body component 410. When the atomizer 30 is installed on the main body component 410, the positive and negative poles of the power supply component in the main body component 410 can be electrically connected to the two electrode bodies 121 respectively, so that a power supply circuit can be formed to supply power to the heating element 110.

[0106] In summary, it is easy for a person skilled in the art to understand that the beneficial effects of the present application are: by burying the heating element in the liquid absorption liquid, the heating element can be closely fitted with the liquid absorption liquid, thereby improving the uniformity of the heat conduction of the heating element; at the same time, by burying the heating element in the liquid absorption liquid, in the process of the atomized liquid entering the liquid absorption liquid from the side of the main body away from the bottom wall and penetrating from the outer surface of the bottom wall, the heating element can also preheat the atomized liquid in the liquid absorption liquid, thereby making the temperature of the atomized liquid uniformly increased, thereby improving the atomization effect of the atomized liquid. Further, by embedding the first embedded portion of the heating element in the annular side wall, the atomized liquid on one side of the liquid absorption surface can be preheated. When the viscosity of the atomized liquid is high, the atomized liquid can be preheated to improve its fluidity, thereby enabling the atomized liquid to enter the liquid absorption liquid more quickly from the liquid absorption surface, and the transmission rate of the atomized liquid in the liquid absorption liquid to the atomizing surface can be increased, thereby replenishing the atomized liquid on one side of the atomizing surface in time to avoid the problem of dry burning of the atomizing core.
