[0035] Embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While several embodiments of the present disclosure are illustrated, it is to be understood that the present disclosure is not to be limited to the precise embodiments and that various changes and modifications can be effected therein by one skilled in the art. It should be understood that the drawings and detailed description thereto are not intended to limit the scope of the present disclosure, but are merely intended to illustrate exemplary aspects of the present disclosure.

[0036] It is to be noted that the headings provided herein are for convenience only and are not to be taken as limiting the disclosure. Various embodiments are described throughout this document, and any type of embodiment can be included under any section. Furthermore, embodiments described in any section can be combined with any other embodiment described in the same section and / or a different section in any manner.

[0037] In the description of embodiments of the disclosure, the term "includes" and its derivatives are to be construed as open-ended, i.e., to the effect that "includes but is not limited to". The term "based on" is to be construed as "based at least in part on". The term "one embodiment" or "the embodiment" are to be construed as "at least one embodiment". The term "some embodiments" is to be construed as "at least some embodiments". Other explicit and implicit definitions can also be included below. The terms "first", "second", etc. can refer to different or the same objects. Other explicit and implicit definitions can also be included below.

[0038] As briefly mentioned before, in cold environment, the viscosity of the atomized substrate rises. When the viscosity of the atomized substrate is too large (e.g. the viscosity of the atomized substrate is greater than 1000 cP), the atomized substrate will be difficult to pass through the porous mechanism in the atomization substrate and reach the heating device, thereby causing insufficient supply of the heating device, and the heating device is prone to dry burning.

[0039] According to the atomization core for an atomization device and the atomization device provided by the disclosure, the above-mentioned problems and other potential problems existing in the conventional solutions are solved or at least partially solved. According to the embodiments of the disclosure, the heating film is covered on the suction side, the atomization side and the inner circumferential surface of the plurality of through holes of the substrate, and the cutting groove is opened on at least the heating film, so as to separate the heating film into different functional areas according to the needs. When a pair of electrodes is energized, the preheating area on the suction side of the substrate works, thereby preheating the atomized substrate. After the atomized substrate is heated, the viscosity of the atomized substrate is reduced, so that the atomized substrate can flow smoothly to the atomization side through the through hole of the substrate. In this way, the stability of the liquid supply of the atomization device is improved, the continuity of the atomization is improved, and the damage to the heating body caused by dry burning of the heating body is reduced.

[0040] Figures 1 to 3 The perspective view, the sectional view and the exploded view of the atomization device 200 are shown respectively. As shown in the perspective view, the sectional view and the exploded view, the atomization device 200 includes an oil cup 80 and an atomization core assembly. The oil cup 80 includes a liquid outlet 81, a containing cavity 82 and a suction inlet 83. The containing cavity 82 is adapted to contain the atomized substrate, the liquid outlet 81 is adapted to supply the atomized substrate in the containing cavity 82 to the suction side 11 of the atomization core 100, and the suction inlet 83 is adapted to discharge the atomized gas after the atomized substrate is heated. The atomization core assembly is coupled to the oil cup 80, and the liquid outlet 81 of the oil cup 80 is in communication with the liquid supply port 22 of the atomization core assembly. Figures 1 to 3 The perspective view, the sectional view and the exploded view of the atomization device 200 are shown respectively. As shown in the perspective view, the sectional view and the exploded view, the atomization device 200 includes an oil cup 80 and an atomization core assembly. The oil cup 80 includes a liquid outlet 81, a containing cavity 82 and a suction inlet 83. The containing cavity 82 is adapted to contain the atomized substrate, the liquid outlet 81 is adapted to supply the atomized substrate in the containing cavity 82 to the suction side 11 of the atomization core 100, and the suction inlet 83 is adapted to discharge the atomized gas after the atomized substrate is heated. The atomization core assembly is coupled to the oil cup 80, and the liquid outlet 81 of the oil cup 80 is in communication with the liquid supply port 22 of the atomization core assembly.

[0041] As shown in Figures 1 to 3 , the accommodating cavity 82 is designed to be suitable for the shape and size of the atomized substrate. The outlet 81 ensures that the atomized substrate can flow from the accommodating cavity 82 of the oil cup 80 to the suction side 11 of the atomization core 100, providing raw materials for the subsequent atomization process. When the user uses the atomization device 200, the user will inhale the atomized and heated gas through the inhalation port 83. The outlet 81 of the oil cup 80 is in communication with the liquid supply port 22 of the atomization core assembly.

[0042] In this way, the atomized substrate flowing out of the outlet 81 of the oil cup 80 can directly enter the liquid supply port 22 of the atomization core assembly, which can ensure smooth flow of the atomized substrate between the oil cup 80 and the atomization core 100, and realize continuous atomization. When the atomization core assembly is powered on, the temperature of the heating film sheet arranged at least on the suction side 11 of the substrate can preheat the atomized substrate on the suction side 11 to improve the flowability of the atomized substrate. The preheated atomized substrate is more likely to contact the heating film sheet 14 and enter the plurality of through holes of the substrate, which helps the heating and atomization of the atomized substrate and can avoid the phenomenon of dry burning of the atomization core 100.

[0043] In some embodiments, as shown in Figures 1 to 3 , the atomization device 200 further comprises a sealing ring 90. The sealing ring 90 is arranged between the oil cup 80 and the atomization seat 20, which can improve the sealing between the two. In this way, when the atomization seat 20 is coupled with the oil cup 80, the atomized substrate in the oil cup 80 can be prevented from leaking along the connection position of the atomization seat 20 and the oil cup 80.

[0044] Figure 4 An exploded view of the atomization core assembly according to an embodiment of the present disclosure is shown. As shown in Figure 4 , the atomization core assembly is composed of at least the atomization seat 20, the sealing gasket 30, the atomization core 100, and a pair of power supply terminals 40. The atomization seat 20 has a mounting groove 21 for fixing and positioning other components, such as the atomization core 100 and the sealing gasket 30. At the same time, the atomization seat 20 is also provided with a liquid supply port 22, which can be connected with an accommodating cavity 82 specially used for storing the atomized substrate (for example, the accommodating cavity 82 of the oil cup 80 mentioned below), which can ensure that the atomized substrate flows smoothly from the accommodating cavity 82 into the mounting groove 21 and contacts the atomization core 100.

[0045] The sealing gasket 30 is mounted in the mounting groove 21 of the atomization seat 20, and the sealing gasket 30 functions to ensure the air tightness of the entire atomization core assembly, preventing the atomized substrate from leaking or external impurities from entering. The atomization core 100 is tightly fixed in the mounting groove 21 by the sealing gasket 30, which not only maintains the structural stability but also ensures good sealing effect.

[0046] In some embodiments, asFigure 4 As shown, the atomization core assembly further includes a base 50. The base 50 is coupled to the atomization seat 20 and the pair of power supply terminals 40, and can support the pair of power supply terminals 40 against the atomization core 100.

[0047] As shown, the atomization seat 20 is provided with the base 50 on the side facing the power supply terminals 40, and the base 50 and the atomization seat 20 can be detachably connected by a buckle structure or screws, etc. The base 50 is provided with a positioning structure, and the two power supply terminals 40 are connected to the positioning structure. In this way, when the base 50 and the atomization seat 20 are coupled, the base 50 can support the two power supply terminals 40 against the atomization core 100, and can ensure the stability of the circuit connection. Figure 4

[0048] As shown, the atomization core assembly further includes a flow stabilizer 60. The flow stabilizer 60 is arranged in the installation groove 21 and located between the sealing gasket 30 and the suction side 11 of the atomization core 100. The flow stabilizer 60 can ensure that the atomization substrate flows to the atomization core 100 at a uniform and stable rate, avoiding the instantaneous over-concentration or over-dilution of the atomization effect caused by uneven liquid supply. Stable liquid supply is conducive to the continuous and uniform evaporation of the atomization substrate by the atomization core 100, producing aerosols of consistent quality, which can improve the user's taste experience. During the atomization process, if the atomization substrate directly impacts the atomization core 100, it may cause liquid droplets to splash, resulting in local overheating, burning or producing bad taste. The flow stabilizer 60 guides the liquid to contact the heating surface gently and orderly, reduces the splashing phenomenon, and ensures the cleanliness and efficiency of the atomization process. Furthermore, the flow stabilizer 60 indirectly affects the humidity of the generated aerosol (i.e. the ratio of vapor to liquid droplets) by adjusting the contact area, contact method or liquid flow rate of the atomization substrate and the atomization core 100, which can meet the user's demand for vapor fullness, and can avoid the discomfort or condensation problem caused by too high humidity. Figure 4

[0049] In some embodiments, the flow stabilizer 60 includes at least one of flow stabilizing cotton, ceramic channels, metal mesh or corrugated tubes.

[0050] As shown, the atomization core assembly further includes a flat pad 70. The flat pad 70 is arranged in the installation groove 21 and located between the sealing gasket 30 and the flow stabilizer 60, and the flat pad 70 includes a liquid inlet hole 71 adapted for the atomization substrate to flow to the flow stabilizer 60. Figure 4

[0051] As shown, the atomization core assembly further includes a flat pad 70. The flat pad 70 is arranged in the installation groove 21 and located between the sealing gasket 30 and the flow stabilizer 60, and the flat pad 70 includes a liquid inlet hole 71 adapted for the atomization substrate to flow to the flow stabilizer 60. Figure 4 ​​​As shown, the flat pad 70 is provided with an inlet hole 71, which can make the atomized substrate in the containing cavity 82 flow to the flow stabilizing member 60. The shape and size of the flat pad 70 are adapted to the shape and size of the atomizing core 100. On the one hand, the flat pad 70 can fix the flow stabilizing member 60 and the atomizing core 100 in the atomizing position. On the other hand, the flat pad 70 can avoid the flow stabilizing member 60 from being deformed after being soaked in the atomized substrate for a long time, thereby enhancing the flow stabilization effect.

[0052] The atomizing core according to the embodiments of the present disclosure will be described below in combination with Figures 5 to 12 . Figure 5 A front structure schematic diagram of the atomizing core according to some embodiments of the present disclosure is shown, Figure 6 A back structure schematic diagram of the atomizing core relative to the front according to some embodiments of the present disclosure is shown. As Figure 5 and Figure 6 shown, the atomizing core of the embodiments of the present disclosure generally comprises a substrate 1, a pair of electrodes 2, and a heating body coupled on the substrate 1. The substrate 1 carries an atomized substrate, and the heating body is used to heat and atomize the atomized substrate.

[0053] As Figure 5 and Figure 6 shown, the substrate 1 comprises an inhalation side 11 and an atomization side 12. The inhalation side 11 is arranged adjacent to a containing cavity in the atomizing device for containing the atomized substrate (also referred to as being arranged on the back of the atomizing core), and the atomization side 12 is arranged on the side of the substrate 1 opposite to the inhalation side 11 (also referred to as being arranged on the front of the atomizing core). The substrate 1 further comprises a plurality of through holes 13, which are distributed on the surface of the substrate 1 in a dot matrix manner. The through holes 13 are configured to pass through from the inhalation side 11 to the atomization side 12, so that the atomized substrate can flow from the inhalation side 11 to the atomization side 12 through the through holes 13, in the process, the atomized substrate is heated and atomized by the heating body coupled on the substrate 1.

[0054] In some embodiments, the cross section of the substrate 1 perpendicular to the normal line can be rectangular, circular, or other arbitrary polygon, and hereinafter the rectangular substrate 1 will be mainly introduced. However, it should be understood that the substrate 1 with other cross sections is also similar, which will not be described here again. In some embodiments, the plurality of substrates 1 can be obtained by shearing a profile. In some alternative embodiments, the substrate 1 can also be separately processed.

[0055] The heating element includes a heating film sheet arranged between the pair of electrodes 2. In some embodiments, the pair of electrodes 2 are arranged at both ends of the length direction of the substrate 1 respectively and are adapted to supply power to the heating film sheet when the pair of electrodes 2 are energized, so that at least a part of the heating film sheet is heated to preheat and / or atomize the atomization substrate. The heating film sheet is attached to at least one of the suction side 11, the atomization side 12 and the inner surface of the plurality of through holes 13 of the atomization substrate 1. In some embodiments, the heating film sheet is attached to the suction side 11, the atomization side 12 and the inner surface of the plurality of through holes 13 of the substrate 1 by electroplating or the like, so that the heating film sheet is continuously attached to the suction side 11, the atomization side 12 and the inner surface of the through holes 13. In this way, the heating film sheet is electrically connected between the atomization side 12 and the part of the heating film sheet on the suction side 11 through the inner surface of the through hole 13.

[0056] The atomization core further includes a plurality of isolation grooves. The isolation grooves are formed on and through the heating film sheet to cut off the electrical connection between the heating film sheet on both sides of the isolation grooves, so as to separate the heating film sheet into a plurality of regions with different conduction states with the electrodes 2. For example, some regions are in a conduction state, i.e., the electrical connection between the electrodes and the regions can be conducted, while some regions are in a non-conduction state, i.e., the electrical connection between the electrodes and the corresponding regions is disconnected. For example, in some embodiments, the isolation grooves can separate the heating film sheet into a first region and a second region, and during the period when the pair of electrodes 2 supply power to the heating film sheet, the current passes through the first region to heat the first region. Due to the separation by the isolation grooves, the second region has no current passing through, so that the second region is not heated (i.e., the conduction state with the electrodes 2 is different). In some embodiments, the isolation grooves can be arranged to extend along the length direction or the width direction of the substrate 1, and the isolation grooves are arranged between adjacent rows or columns of the plurality of through holes 13 in a dot matrix manner.

[0057] In some embodiments, the isolation grooves can also be formed on the heating film sheet and the substrate 1 at the same time, so as to reduce the processing precision of the isolation grooves and also improve the stability of the separation of different regions by the isolation grooves. In some embodiments, the isolation grooves can be formed by mechanical cutting or laser cutting. In other embodiments, the isolation grooves can also be formed by etching or the like.

[0058] In some embodiments, one end of the isolation grooves can extend to the edge of the substrate 1 and be flush with the edge of the substrate 1. In this way, when a plurality of substrates 1 are processed from a complete silicon wafer or glass substrate, the difficulty of opening the isolation grooves can be reduced and the processing flow can be simplified.

[0059] The plurality of cutting grooves comprises at least one pair of first grooves 3, the first grooves 3 are arranged on the suction side 11 of the substrate 1, and the two first grooves 3 in the pair of first grooves 3 are spaced apart by a predetermined distance, so that a preheating area 14 is formed between the two first grooves 3, the heating film pieces located in the preheating area 14 can heat up after being powered on, thereby heating the atomized substrate on the suction side 11 of the substrate 1, thereby reducing the viscosity of the atomized substrate, so that the atomized substrate can flow more smoothly from the through hole 13 to the atomization side 12 of the substrate 1. In some embodiments, the first grooves 3 can extend along the length direction of the substrate 1, and the two first grooves 3 in the pair of first grooves 3 are arranged parallel to each other along the width direction perpendicular to the length direction of the substrate 1.

[0060] In some embodiments, the isolation groove further comprises at least one pair of second grooves 4, the at least one pair of second grooves 4 are arranged on the atomization side 12 of the substrate 1 and are respectively aligned with the at least one pair of first grooves 3 arranged on the suction side 11 along the normal direction perpendicular to the plane on which the substrate 1 is located. The two second grooves 4 in the pair of second grooves 4 are spaced apart by a predetermined distance, so that a connecting area corresponding to the preheating area 14 can be formed between the two second grooves 4.

[0061] In some embodiments, the isolation groove further comprises at least one third groove 5, the third groove 5 is arranged between the pair of second grooves 4 and respectively extends to the two second grooves 4, and the third groove 5 separates the connecting area into two power supply areas 15 respectively close to the pair of electrodes 2. The heating film pieces in the power supply area 15 are electrically connected to the corresponding electrodes 2, and the heating film pieces in the power supply area 15 are also electrically connected to the heating film pieces in the preheating area 14 on the suction side 11 through the heating film pieces attached to the inner surface of the through hole 13 in the power supply area 15. In this way, when the pair of electrodes 2 is powered on, the heating film pieces in the preheating area 14 are electrically connected to the electrodes 2 through the heating film pieces in the two power supply areas 15 on the atomization side 12, thereby causing the heating film pieces in the preheating area 14 to be turned on and heated.

[0062] In some embodiments, the isolation groove comprises a pair of third grooves 5, the pair of third grooves 5 are arranged along the length direction of the substrate 1 and are spaced apart by a predetermined distance between the pair of third grooves 5, so that the pair of third grooves 5 are arranged close to the corresponding electrodes 2. The pair of third grooves 5 separates the connecting area into the power supply areas 15 arranged on both sides of the pair of third grooves 5. In this way, the pair of electrodes 2 can supply power to the heating film pieces in the preheating area 14 through the heating film pieces in the two power supply areas 15.

[0063] As Figure 5 and Figure 6As shown, in some embodiments, the isolation grooves include two pairs of first grooves 3 and fourth grooves 6 arranged at the inhalation side 11, and two pairs of second grooves 4 and two pairs of third grooves 5 arranged at the atomization side 12. The two pairs of first grooves 3 are respectively spaced apart by a predetermined distance along the width direction of the substrate 1, and the two pairs of second grooves 4 are respectively aligned with the two pairs of first grooves 3 along the normal direction. The two pairs of third grooves 5 respectively correspond to the two pairs of second grooves 4, and each pair of third grooves 5 is arranged between the corresponding pair of second grooves 4, thereby separating two power supply areas 15 in the connection area between the pair of second grooves 4.

[0064] After the heating film pieces in the two power supply areas 15 are respectively coupled with a pair of electrodes 2, the heating film pieces of the preheating area 14 arranged at the inhalation side 11 can be powered. After the heating film pieces of the preheating area 14 are powered, the atomization substrate is heated, so that the viscosity of the atomization substrate is reduced after being preheated, thereby enabling the atomization substrate to flow more smoothly from the inhalation side 11 to the atomization side 12 through the through hole 13. The fourth grooves 6 are arranged between the two pairs of first grooves 3, and the two ends of the fourth grooves 6 respectively extend to the adjacent two pairs of first grooves 3.

[0065] The fourth grooves 6 are adapted to isolate the heating film pieces between the two pairs of first grooves 3, so that the heating film pieces between the adjacent two pairs of first grooves 3 are open circuit, thereby the heating film pieces between the adjacent two pairs of first grooves 3 do not work during the power supply of the electrodes 2, thereby the preheating effect of the heating film pieces on the atomization substrate can be controlled, and the flow speed of the atomization substrate to the atomization side 12 can be further controlled. The heating film pieces between the two pairs of second grooves 4 at the atomization side 12 are respectively coupled with a pair of electrodes 2 at the two ends, so that the heating film pieces between the two pairs of second grooves 4 are heated after a pair of electrodes 2 is powered, and the atomization substrate flowing to the atomization side 12 through the through hole 13 is atomized.

[0066] Figure 7 As shown in the front view structural schematic diagram of the atomization core according to some other embodiments of the present disclosure, Figure 8 As shown in the back view structural schematic diagram of the atomization core relative to the front view according to some other embodiments of the present disclosure, Figure 7 and Figure 8 As shown, in some embodiments, the isolation grooves include two pairs of first grooves 3 and fourth grooves 6 arranged at the inhalation side 11, and two pairs of second grooves 4 and two pairs of third grooves 5 arranged at the atomization side 12. The two pairs of first grooves 3 are respectively spaced apart by a predetermined distance along the width direction of the substrate 1, and the two pairs of second grooves 4 are respectively aligned with the two pairs of first grooves 3 along the normal direction. The two pairs of third grooves 5 respectively correspond to the two pairs of second grooves 4, and each pair of third grooves 5 is arranged between the corresponding pair of second grooves 4, thereby separating two power supply areas 15 in the connection area between the pair of second grooves 4.

[0067] The four third grooves 5 are arranged between the four pairs of second grooves 4 respectively, and the third grooves 5 extend to a pair of second grooves 4 respectively. Thus, the third grooves 5 divide the connecting area between a pair of second grooves 4 into a power supply area 15, which is arranged at the side of the third groove 5 close to the corresponding electrode 2. Thus, the electrode 2 can supply power to the heating film of the preheating area 14 of the inhalation side 11 through the heating film of the power supply area 15.

[0068] Figure 9 Fig. 2 shows a schematic diagram of the front structure of an atomizing core according to some other embodiments of the present disclosure, Figure 10 Fig. 3 shows a schematic diagram of the back structure of an atomizing core relative to the front according to some other embodiments of the present disclosure. As shown in Figure 9 and Figure 10 As shown in some embodiments, the isolation groove includes a pair of first grooves 3 arranged at the inhalation side 11, a pair of second grooves 4 arranged at the atomization side 12, and a third groove 5. The pair of first grooves 3 is arranged at the middle of the width direction of the substrate 1, and the two first grooves 3 in the pair of first grooves 3 are separated by a predetermined distance, so that the two first grooves 3 form a preheating area 14 at the middle of the substrate 1.

[0069] The third groove 5 is arranged between the pair of second grooves 4, and the two ends of the third groove 5 extend to the two second grooves 4 respectively. The third groove 5 is adapted to divide the connecting area between the pair of second grooves 4 into two power supply areas 15, and similar to other embodiments, the heating films in the two power supply areas 15 are coupled with the corresponding electrodes 2 respectively, so that when the electrodes 2 are turned on, the heating film of the preheating area 14 at the inhalation side 11 works under the connection of the heating films of the two power supply areas 15, thereby preheating the atomization substrate. On the other hand, while the heating films of the power supply areas 15 are connected to the heating films of the preheating area 14, the heating films of the power supply areas 15 can also heat up by themselves, thereby atomizing the atomization substrate flowing to the atomization side 12.

[0070] Figure 11 Fig. 2 shows a schematic diagram of the front structure of an atomizing core according to some other embodiments of the present disclosure, Figure 12 Fig. 3 shows a schematic diagram of the back structure of an atomizing core relative to the front according to some other embodiments of the present disclosure. As shown in Figure 11 and Figure 12 As shown in some embodiments, the isolation groove includes a pair of first grooves 3 arranged at the inhalation side 11, a pair of second grooves 4 arranged at the atomization side 12, and a third groove 5. The pair of first grooves 3 is arranged at the middle of the width direction of the substrate 1, and the two first grooves 3 in the pair of first grooves 3 are separated by a predetermined distance, so that the two first grooves 3 form a preheating area 14 at the middle of the substrate 1.

[0071] In this way, the pair of first slots 3 and the pair of fifth slots 7 are connected end to end in sequence and form a substantially rectangular frame. The pair of first slots 3 and the pair of fifth slots 7 together divide the heat conductive film on the atomization side 12 to form a preheating area 14 within the rectangular frame. Similarly, the second slots 4 arranged on the suction side 11 extend along the length of the substrate 1 and the pair of second slots 4 are arranged along the width of the substrate 1. The third slots 5 extend along the width of the substrate 1 and the pair of third slots 5 are arranged along the length of the substrate 1.

[0072] The pair of third slots 5 are arranged between the pair of fifth slots 7, so that the heating film in the connection area divided by the pair of third slots 5 can be connected to the heating film in the preheating area 14 through the heating film on the inner surface of the through hole 13, thereby allowing the heating film in the preheating area 14 to work and at least heat the atomization substrate after the pair of electrodes 2 are powered on. In some embodiments, the heating power of the preheating area 14 can also be appropriately increased, so that the atomization substrate is directly atomized on the suction side 11 of the substrate 1 and flows to the atomization side 12 of the substrate 1 through the through hole 13.
