Description

[0001] The present application belongs to the technical field of electronic atomization devices, and in particular, relates to an electronic atomization device and an atomizer and an atomization core thereof. Background Art

[0002] Existing electronic atomization devices such as electronic cigarettes can usually atomize atomized liquids such as smoke oil. Usually, a ceramic base 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 one side of the ceramic base. A heating element can usually be set on the side of the ceramic base away from the liquid storage space of the atomized liquid to heat and atomize the permeated atomized liquid.

[0003] However, the existing metal heating element is embedded on the surface of the ceramic base and then sintered together. Due to the difference in thermal conductivity between the heating element and the ceramic base, the heating element may separate slightly from the ceramic after heating, resulting in uneven heating temperature when heating the atomized liquid in subsequent use, which leads to poor atomization effect of the atomized liquid, and in severe cases, burnt smell and odor. In addition, for atomized liquid with higher viscosity, the liquid conduction rate of the ceramic base will decrease, resulting in insufficient supply of atomized liquid on the ceramic surface where the heating element is set, resulting in dry burning.

[0042] See also Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of the atomizer core provided by the present application; Figure 2 yes Figure 1 A schematic diagram of the structure of the heating element in the atomizer core is shown.

[0043] The atomizing core 10 includes an imbibing liquid 100 and a heating element 200. The atomizing core 10 can be used to heat the atomizing liquid, thereby atomizing the atomizing liquid.

[0044] A plurality of micropores are formed in the absorbing liquid 100, through which the atomized liquid can enter the absorbing liquid 100, or the atomized liquid can penetrate from one side to the other side of the absorbing liquid 100 through the micropores. The plurality of micropores in the absorbing liquid 100 can also store the atomized liquid. The heating element 200 is partially buried in the absorbing liquid 100.

[0045] The liquid-absorbing body 100 may be a sintered porous body, specifically, a ceramic porous body. It is understandable that in some other embodiments, the sintered porous body may not be limited to a ceramic porous body, for example, it may be a glass porous body or a glass-ceramic porous body.

[0046] The material of the absorbent liquid 100 may be any one or more of aluminum oxide, silicon oxide, silicon nitride, silicate and silicon carbide.

[0047] 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 100, and then the heating element 200 can be at least partially buried in the pre-blank. By heating and sintering, the absorbent liquid 100 partially encapsulating the heating element 200 can be formed, and the heating element 200 is tightly combined with the absorbent liquid 100.

[0048] The shape and size of the liquid absorbing liquid 100 are not limited and can be selected as needed. In the present embodiment, specifically, the liquid absorbing liquid 100 includes a main body 102 that is roughly in the shape of a rectangular parallelepiped, such as a terraced shape, and a boss portion 101 disposed on the bottom surface of the main body 102. The heating element 200 can be partially buried in the boss portion 101. The portion of the heating element 200 located outside the liquid absorbing liquid 100 can be disposed on one side of the top surface of the boss portion 101 (i.e., the side of the boss portion 101 away from the main body 102). In the present embodiment, the liquid absorbing liquid 100 is an integrally formed structure.

[0049] Among them, the top surface of the boss portion 101 of the absorbing liquid 100 is the atomizing surface 1001 of the absorbing liquid 100, and the surface on the other side of the absorbing liquid 100 opposite to the atomizing surface 1001 can be represented as the absorbing surface 1002 of the absorbing liquid 100, wherein the absorbing surface 1002 of the absorbing liquid 100 can be in contact with the atomized liquid, so that the atomized liquid can enter the absorbing liquid 100 from the side of the main body 102 away from the boss portion 101, and can penetrate from the top surface of the boss portion 101 (that is, the atomized liquid can penetrate the absorbing liquid 100 through the absorbing surface 1002 of the absorbing liquid 100 and then penetrate from the atomizing surface 1001 of the absorbing liquid 100). When the atomized liquid penetrates from the top surface of the boss portion 101, the part of the heating element 200 located outside the absorbing liquid 100 can heat and atomize the penetrated atomized liquid. Furthermore, a groove may be provided on a side of the main body 102 of the liquid absorbing member 100 away from the boss 101 for accommodating the atomized liquid.

[0050] In this embodiment, by burying the heating element 200 in the absorbing liquid 100, the heating element 200 can be closely attached to the absorbing liquid 100, thereby improving the uniformity of heat conduction of the heating element 200; at the same time, by burying the heating element 200 in the absorbing liquid 100, in the process that the atomized liquid enters the absorbing liquid 100 from the side of the main body 102 away from the boss portion 101 and penetrates from the top surface of the boss portion 101, the heating element 200 can also preheat the atomized liquid in the absorbing liquid 100, thereby making the temperature of the atomized liquid uniformly increased, thereby improving the atomization effect of the atomized liquid. And for the atomized liquid with high viscosity, the part of the heating element 200 buried in the absorbing liquid 100 can reduce the viscosity of the atomized liquid by preheating the atomized liquid, thereby improving the fluidity and preventing dry burning due to insufficient liquid supply to the atomizing surface.

[0051] In this embodiment, further, the atomization effect of the atomized liquid can be further improved by configuring the heating element 200 as a three-dimensional structure.

[0052] Please refer to Figure 2 .

[0053] In this embodiment, the heating element 200 may include a heating element 210, a first connecting element 220 and a second connecting element 230. The first connecting element 220 and the second connecting element 230 may be connected to opposite ends of the heating element 210, respectively.

[0054] The heating element 210 may include a first heating portion 211 and a second heating portion connected to each other.

[0055] Among them, the number of the first heating part 211 and the second heating part can both be one, one end of the first heating part 211 can be connected to the first connecting member 220, and the other end is connected to the second heating part, and the end of the second heating part away from the first heating part 211 is connected to the second connecting member 230.

[0056] Alternatively, the number of the first heating parts 211 may be at least two, wherein the two first heating parts 211 may be connected to the first connecting member 220 and the second connecting member 230 respectively, and the second heating part may be connected in series between the two first heating parts 211 .

[0057] Specifically, the second heating portion may include at least two first sub-heating portions 212 and second sub-heating portions 213. Two ends of the first sub-heating portion 212 are connected to the first heating portion 211 and the second sub-heating portion 213, respectively.

[0058] In this embodiment, the heating element 210 can be a linear heating unit, and the first heating part 211 and the second sub-heating part 213 are both in a straight line. The heating element 210 can be bent multiple times to form a plurality of first heating parts 211, a plurality of first sub-heating parts 212, and a plurality of second sub-heating parts 213. Among them, the plurality of second sub-heating parts 213 are buried in the liquid absorbing liquid 100, that is, the side of each second sub-heating part 213 is completely covered by the porous ceramic material of the liquid absorbing liquid 100, and the end is connected to the adjacent first sub-heating part 212.

[0059] In this embodiment, when the heating element 210 is bent multiple times to form a plurality of first heating parts 211, a plurality of first sub-heating parts 212, and a plurality of second sub-heating parts 213, a bending part can be formed between two connected heating parts (the first heating part 211, the first sub-heating part 212, or the second sub-heating part 213), and the bending angle of the bending part is 10° to 170°. For example, taking the connected first heating part 211 and the first sub-heating part 212 as an example, the first heating part 211 and the first sub-heating part 212 are both linear, and the connection between the first heating part 211 and the first sub-heating part 212 can be a bending part, and the bending angle of the bending part can be 10° to 170°, wherein the preferred bending angle of the bending part can be 80° to 100°, for example, the bending angle of the bending part between the first heating part 211 and the first sub-heating part 212 can be set to 80°, 90° or 100°. In a preferred embodiment, the bending angle of the bending portion can be set to 90°. The heating element 210 can be a metal strip or a metal wire, and the cross section of the heating element 210 can be any one of a circle, a square, a rectangle, an ellipse, etc. In other embodiments, the cross section of the heating element 210 can also be a regular polygon such as a regular hexagon or a regular octagon.

[0060] In this embodiment, the heating element 210 forms a three-dimensional structure. Among them, the multiple first heating parts 211 in the heating element 210 can be arranged in the first plane, and the multiple second sub-heating parts 213 are arranged in the second plane spaced apart from the first plane, wherein, in a preferred embodiment, the first plane and the second plane can be parallel and spaced apart. That is, the center lines of the multiple first heating parts 211 in the heating element 210 can be arranged in the first plane; the center lines of the multiple second sub-heating parts 213 in the heating element 210 can be arranged in the second plane, and the first plane and the second plane are parallel and spaced apart. The multiple first sub-heating parts 212 in the heating element 210 can connect the multiple first heating parts 211 and the multiple second sub-heating parts 213. Specifically, the opposite ends of each first sub-heating part 212 can be connected to the first heating part 211 and the second sub-heating part 213, respectively.

[0061] In this embodiment, a plurality of first heating parts 211 are arranged in parallel and at intervals in the first plane. A plurality of second sub-heating parts 213 are arranged in a second plane parallel to the first plane, and a plurality of first sub-heating parts 212 can be arranged in a third plane perpendicular to the first plane. Among them, since the first heating part 211 can be a linear heating element, both opposite ends of which can be connected to the second heating part, the number of third planes can be set to two, so that the first sub-heating parts 212 on the opposite sides of the first heating part 211 are respectively located in these two third planes; wherein, the two third planes can also be arranged at intervals and in parallel.

[0062] In this embodiment, the first plane is the plane where the atomized surface 1001 is located.

[0063] Furthermore, in this embodiment, the heating element 210 can be a metal strip or a metal wire, or can also be a patterned metal sheet. The heating element 210 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.

[0064] When the heating element 210 is a metal strip or a metal wire, the diameter of the cross section of the heating element 210 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 210 is a metal sheet, the heating element 210 may be a metal sheet with a thickness in the range of 0.01 mm to 2 mm.

[0065] When the heating element 210 is bent to form a plurality of first heating parts 211, a plurality of first sub-heating parts 212 and a plurality of second sub-heating parts 213, 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.

[0066] As described in the above embodiment, the heating element 210 with a three-dimensional structure is formed by multiple bending. In other embodiments, the heating element 210 with a three-dimensional structure can also be obtained by one or more methods such as mold stamping, casting, mechanical weaving, chemical etching, etc.

[0067] Alternatively, in other embodiments, a plurality of heating elements 210 may be mechanically woven into a mesh structure, and then the mesh heating elements are bent to form a heating element 210 having a three-dimensional structure.

[0068] Alternatively, multiple sub-linear heating elements with smaller diameters may be used to form a heating element 210 with a larger diameter by winding, bonding or welding. Then, the heating element 210 with a larger diameter is bent to form a three-dimensional structure having multiple first heating parts 211, multiple first sub-heating parts 212 and multiple second sub-heating parts 213.

[0069] See also Figure 3-Figure 4 . Figure 3 yes Figure 1 A schematic structural diagram of another embodiment of the atomizer core is shown; Figure 4 yes Figure 3 A schematic diagram of the structure of the heating element in the atomizer core is shown.

[0070] In this embodiment, a through hole 2101 may also be provided on the heating unit (including the first heating part 211, the first sub-heating part 212 and / or the second sub-heating part 213) of the heating element 210. There may be multiple through holes 2101, and the multiple through holes 2101 may be arranged at equal intervals in sequence along the length direction of the heating unit. In this solution, the through holes 2101 may be provided on the first heating part 211, the first sub-heating part 212 and the second sub-heating part 213. In its embodiment, the multiple through holes 2101 may be provided on the first heating part 211, the first sub-heating part 212 or the second sub-heating part 213.

[0071] In this embodiment, the first sub-heating portion 212 or the second sub-heating portion 213 constitutes a U-shaped second heating portion. In other embodiments, the second heating portion may also be V-shaped (i.e., two first sub-heating portions 212 are directly connected, and the second sub-heating portion 213 is omitted). In other embodiments, the second heating portion may also be arc-shaped.

[0072] Therefore, in the present embodiment, a plurality of through holes are provided on the heating unit of the heating element 210, so that the stability of the combination between the heating element 210 and the absorbing liquid 100 can be further improved, so that the heat emitted by the heating element 210 can be evenly diffused into the absorbing liquid 100, thereby preventing the problem of excessively high local temperature of the heating element 210 caused by heat accumulation in a local area of ​​the heating element 210 due to poor contact with the absorbing liquid 100, and at the same time ensuring that the absorbing liquid 100 can be quickly and evenly heated, thereby improving the atomization effect of the atomized liquid.

[0073] Among them, it should be noted that, in this embodiment, a through hole 2101 is opened on the heating element 210 to improve the stability of the combination of the heating element 210 and the absorbent liquid 100, and the uniformity of heat conduction; in its embodiment, a plurality of blind holes can also be opened on the heating unit of the heating element 210, and similarly, a plurality of blind holes can also be arranged in sequence at equal intervals along the length direction of the heating element 210.

[0074] When the heating element 210 has a through hole 2101 , the through hole 2101 may be a circular hole, and the diameter of the through hole 2101 may be set to 0.01-1.00 mm, for example, the diameter of the through hole 2101 may be set to 0.01 mm, 0.5 mm or 1 mm.

[0075] When a blind hole is opened on the heating element 210, 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.

[0076] The distance between two adjacent through holes 2101 (or blind holes) can be set to 0.03 mm to 1.00 mm.

[0077] Furthermore, as described above, the heating element 200 is partially buried in the absorbent liquid 100. Specifically, the second sub-heating portion 213 and at least part of the first sub-heating portion 212 may be buried in the absorbent liquid 100. That is, the first heating portion 211 of the heating element 210 may be fully or partially exposed outside the absorbent liquid 100, the second sub-heating portion 213 is buried in the absorbent liquid 100, and the first sub-heating portion 212 may also be fully or partially buried in the absorbent liquid 100. When the first sub-heating portion 212 is partially buried in the absorbent liquid 100, it means that the part close to the connection end of the first sub-heating portion 212 and the second sub-heating portion 213 is buried in the absorbent liquid 100.

[0078] In the present embodiment, a plurality of second sub-heating parts 213 are all buried in the liquid absorbing liquid 100, and a plurality of first sub-heating parts 212 are inserted into the liquid absorbing liquid 100 and one end is exposed and connected to the first heating part 211. A plurality of first heating parts 211 are all exposed and arranged on the top surface of the boss part 101. Optionally, a plurality of first heating parts 211 can be arranged on one side of the atomizing surface 1001 in the liquid absorbing liquid 100 and contact the atomizing surface 1001. The atomizing surface 1001 can be a plane, so that the consistency of the atomization heating of the atomizing surface 1001 by the first heating part 211 can be increased, thereby improving the atomization efficiency. Similarly, the liquid absorbing surface 1002 can also be a plane to achieve better consistency in the liquid conduction rate of the atomized liquid.

[0079] Therefore, the partial heating element 200 located in the absorbing liquid 100 can preheat the atomized liquid in the absorbing liquid 100, while the partial heating element 200 located outside the absorbing liquid 100 can further heat the preheated atomized liquid that permeates from the absorbing liquid 100, so that the atomized liquid can be quickly and evenly atomized.

[0080] Please refer to further Figure 2 or Figure 4 .

[0081] In this embodiment, the first connecting member 220 and the second connecting member 230 of the heating element 200 can be two heating electrode plates. The first connecting member 220 and the second connecting member 230 can be respectively connected to the opposite ends of the heating element 210 to form the positive and negative poles of the heating element 210. By arranging connecting wires on the first connecting member 220 and the second connecting member 230, the heating element 210 can be electrically connected to an external power source, so that the heating element 210 can be powered, thereby causing the heating element 210 to generate heat.

[0082] Specifically, the first connector 220 and the second connector 230 may both include an electrode sheet 221 and a support sheet 222. The electrode sheets 221 of the first connector 220 and the second connector 230 may be respectively connected to opposite ends of the heating element 210. The electrode sheet 221 may be arranged on the same plane as the first heating portion 211, that is, the center line of the electrode sheet 221 is located in the first plane, and one end of the support sheet 222 is connected to the electrode sheet 221, and the other end extends in a direction close to the second plane.

[0083] In this embodiment, the heating element 200 can be partially embedded in the blank of the absorbent liquid 100 by gradually embedding the support sheet 222 away from the electrode sheet 221 into the blank of the absorbent liquid 100 .

[0084] Among them, a through groove 2221 can also be set on the support sheet 222. When the support sheet 222 is gradually buried in the blank of the absorbent liquid 100, the powder material or slurry forming the absorbent liquid 100 can enter the through groove 2221. After the sintering and fixing of the blank of the absorbent liquid 100 is completed, the combination stability of the heating element 200 and the absorbent liquid 100 can be further improved.

[0085] In this embodiment, the first connecting member 220 or the second connecting member 230 may include at least two supporting sheets 222 , and the two supporting sheets 222 may be respectively connected to opposite ends of the electrode sheet 221 .

[0086] It should be noted that the electrode sheet 221 and the support sheet 222 of the first connecting member 220 and the second connecting member 230 can be formed as one piece, wherein specifically, a sheet material can be formed first, and then the opposite ends of the sheet material can be bent, wherein the opposite ends of the bent sheet material can constitute the support sheet 222, and the middle area of ​​the sheet material can constitute the electrode sheet 221.

[0087] Alternatively, in other embodiments, the electrode sheet 221 and the support sheet 222 of the first connecting member 220 and the second connecting member 230 can be formed separately, wherein the support sheet 222 can be fixedly connected to the opposite ends of the electrode sheet 221 by bonding or welding, thereby forming the first connecting member 220 or the second connecting member 230.

[0088] Furthermore, the present application also provides an atomizer. Figure 5-Figure 7 . Figure 5 It is a structural schematic diagram of an embodiment of an atomizer provided by the present application; Figure 6 yes Figure 5 A cross-sectional view of the atomizer shown; Figure 7 yes Figure 6 A partial enlarged view of the atomizer in area A is shown.

[0089] The atomizer 30 includes an atomizing sleeve 310 , a mounting seat 320 and an atomizing core 10 .

[0090] 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.

[0091] 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 10, so that the atomizing core 10 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.

[0092] The atomizer core 10 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 10 . After the atomized liquid is stored in the liquid storage space, the atomized liquid seals the first pressure regulating channel 322 .

[0093] 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 10, or leak from the connection between the atomizing core 10 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 10 may easily cause a burning smell during operation due to insufficient liquid supply, which brings a bad suction experience to the user.

[0094] Furthermore, the present application also provides an electronic atomization device. Figure 8 , Figure 8 It is a structural schematic diagram of an embodiment of an electronic atomization device provided in the present application.

[0095] 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 sheets 221 of the first connector 220 and the second connector 230 respectively, so that a power supply circuit can be formed to supply power to the heating element 210.

[0096] In summary, it is easy for those skilled in the art to understand that the beneficial effects of the present application are: by burying the heating element in the absorbent liquid, the heating element and the absorbent liquid can be closely fitted, so that the heat generated by the heating element can be quickly transferred to the absorbent liquid, thereby preventing the heating element from being too hot, ensuring that the ceramic substrate heats up quickly, and distributing the heat on the surface of the absorbent liquid, so that the surface temperature of the heating surface of the absorbent liquid is uniform, without the phenomenon of local excessive temperature; at the same time, by bending the heating element into a three-dimensional structure, the atomized liquid in the absorbent liquid can be preheated by the heating element, so that the temperature of the atomized liquid can be uniform. The heating element is lifted evenly, thereby improving the atomization effect of the atomized liquid. This solution has a good heating effect for atomized liquid with high viscosity and poor fluidity. By arranging multiple through holes on the heating element, the contact area between the heating element and the liquid absorbing material can be increased, so that the heat emitted by the heating element can be evenly and quickly diffused into the liquid absorbing material, thereby preventing the local area of ​​the linear heating element from accumulating heat due to poor contact with the liquid absorbing material, thereby preventing the problem of excessive local temperature of the linear heating element. At the same time, it can ensure that the liquid absorbing material can be quickly and evenly heated, thereby improving the atomization effect of the atomized liquid.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
