[0035] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0036] It should be noted that the titles of any sections / subsections provided herein are not restrictive. Various embodiments are described throughout this article, and any type of embodiment may be included under any section / subsection. In addition, the embodiments described in any section / subsection may be combined in any manner with any other embodiments described in the same section / subsection and / or different sections / subsections.

[0037] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may be included below. The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.

[0038] As briefly mentioned above, in a cold environment, the viscosity of the atomized matrix increases. When the viscosity of the atomized matrix is ​​too high (for example, the viscosity of the atomized matrix is ​​greater than 1000 cP), it is difficult for the atomized matrix to pass through the porous structure in the atomized substrate and reach the heating device, thereby resulting in insufficient liquid supply to the heating device, and the heating device is prone to dry burning.

[0039] According to the present disclosure, an atomizer core for an atomizer device and an atomizer device are provided to solve or at least partially solve the above-mentioned problems and other potential problems existing in traditional solutions. According to an embodiment of the present disclosure, by covering the heating film on the suction side, the atomization side and the inner circumference of multiple through holes of the substrate, and by providing at least a cutting groove on the heating film, the heating film is divided into different functional areas according to needs. When a pair of electrodes are energized, the preheating zone on the suction side of the substrate works, thereby generating waste heat for the atomization matrix. After the atomization matrix is ​​heated, the viscosity decreases, so that it can smoothly pass through the through holes of the substrate and flow to the atomization side. Thereby, the stability of the liquid supply of the atomizer device is improved, the continuity of atomization is improved, and the situation where the heating element is dry-burned and the heating element is damaged is reduced.

[0040] Figures 1 to 3 The three-dimensional view, cross-sectional view and exploded view of the atomizing device 200 are shown respectively. Figures 1 to 3 As shown, the atomization device 200 includes an oil cup 80 and an atomization core assembly. The oil cup 80 includes a liquid outlet 81, a receiving chamber 82, and an inlet 83. The receiving chamber 82 is suitable for receiving an atomization matrix, the liquid outlet 81 is suitable for allowing the atomization matrix in the receiving chamber 82 to flow to the inlet side 11 of the atomization core 100, and the inlet 83 is suitable for discharging the atomized gas after the atomization matrix is ​​heated. The atomization core assembly is coupled to the oil cup 80, and the liquid outlet 81 of the oil cup 80 is connected to the liquid supply port 22 of the atomization core assembly.

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

[0042] In this way, after the atomized matrix flows out of the liquid outlet 81 of the oil cup 80, it can directly enter the liquid supply port 22 of the atomizer core assembly, which can ensure that the atomized matrix can flow smoothly between the oil cup 80 and the atomizer core 100, and realize a continuous atomization process. When the atomizer core assembly is powered on, the temperature of the heating film arranged at least on the suction side 11 of the substrate increases, and the atomized matrix on the suction side 11 can be preheated to improve the fluidity of the atomized matrix. The preheated atomized matrix is ​​more likely to contact the heating film 14 and enter the multiple through holes of the substrate, which is conducive to the heating and atomization of the atomized matrix, and can avoid the phenomenon of dry burning of the atomizer core 100.

[0043] In some embodiments, Figures 1 to 3 As shown, the atomizing device 200 further includes a sealing ring 90. The sealing ring 90 is disposed between the oil cup 80 and the atomizing seat 20 to improve the sealing between the two. In this way, when the atomizing seat 20 is coupled with the oil cup 80, the atomized matrix in the oil cup 80 can be prevented from leaking along the connection position between the atomizing seat 20 and the oil cup 80.

[0044] Figure 4 1 shows an exploded view of an atomizer core assembly according to an embodiment of the present disclosure. Figure 4 As shown, the atomizer core assembly is at least composed of an atomizer seat 20, a sealing gasket 30, an atomizer core 100 and a pair of power supply terminals 40. The atomizer seat 20 has a mounting groove 21, which is used to fix and position other components, such as fixing the atomizer core 100 and the sealing gasket 30. At the same time, the atomizer seat 20 is also provided with a liquid supply port 22, which can be connected to a receiving cavity 82 specifically used to store atomized substrates (such as the receiving cavity 82 of the oil cup 80 mentioned below), which can ensure that the atomized substrate flows smoothly from the receiving cavity 82 into the mounting groove 21 and contacts the atomizer core 100.

[0045] The sealing gasket 30 is installed in the mounting groove 21 of the atomizer seat 20. The function of the sealing gasket 30 is to ensure the airtightness inside the entire atomizer core assembly to prevent leakage of the atomized matrix or entry of external impurities. The atomizer core 100 is tightly fixed in the mounting groove 21 by the sealing gasket 30, which not only maintains structural stability but also ensures a good sealing effect.

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

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

[0048] In some embodiments, Figure 4 As shown, the atomizer core assembly also includes a flow stabilizer 60. The flow stabilizer 60 is arranged in the mounting groove 21 and is located between the sealing pad 30 and the inhalation side 11 of the atomizer core 100. The flow stabilizer 60 can ensure that the atomized matrix flows to the atomizer core 100 at a uniform and stable rate, avoiding the instantaneous over-concentrated or over-thin atomization effect caused by uneven liquid supply. Stable liquid supply is conducive to the continuous and uniform evaporation of the atomized matrix by the atomizer core 100, producing aerosols of consistent quality, which can enhance the user's taste experience. During the atomization process, if the atomized matrix directly impacts the atomizer core 100, it may cause droplets to splash, resulting in local overheating, burning or producing bad taste. The flow stabilizer 60 reduces splashing by guiding the liquid to contact the heating surface smoothly and orderly, thereby ensuring 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 steam to liquid droplets) by adjusting the contact area, contact method or liquid flow rate between the atomizing matrix and the atomizing core 100, thereby meeting the user's demand for steam fullness and avoiding mouth and nose discomfort or condensation problems caused by excessive humidity.

[0049] In some embodiments, the flow stabilizer 60 includes at least one of a flow stabilizer cotton, a ceramic pore, a metal mesh, or a bellows.

[0050] In some embodiments, Figure 4 As shown, the atomizer core assembly further includes a flat gasket 70 . The flat gasket 70 is arranged in the mounting groove 21 and located between the sealing gasket 30 and the flow stabilizer 60 , and the flat gasket 70 includes a liquid inlet 71 , which is suitable for allowing the atomized substrate to flow to the flow stabilizer 60 .

[0051] like Figure 4As shown, the flat pad 70 is provided with a liquid inlet hole 71, and the liquid inlet hole 71 can allow the atomized matrix in the accommodating cavity 82 to 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 prevent the flow stabilizing member 60 from being deformed after being soaked in the atomized matrix for a long time, thereby enhancing the flow stabilizing effect.

[0052] The following will be combined Figures 5 to 12 To describe the atomizer core according to an embodiment of the present disclosure. Figure 5 The front structural diagram of the atomizer core according to some embodiments of the present disclosure is shown. Figure 6 FIG. 1 shows a schematic diagram of the back structure of the atomizer core relative to the front according to some embodiments of the present disclosure. Figure 5 and Figure 6 As shown, the atomizer core of the embodiment of the present disclosure generally includes a substrate 1, a pair of electrodes 2, and a heating element coupled to the substrate 1. The substrate 1 carries an atomizing substrate, and the heating element is used to heat the atomizing substrate and atomize the atomizing substrate.

[0053] like Figure 5 and Figure 6 As shown, the substrate 1 includes an inhalation side 11 and an atomization side 12. The inhalation side 11 is arranged adjacent to a accommodating cavity for accommodating an atomization substrate in an atomization device (also referred to as being arranged on the back of the atomization core), and the atomization side 12 is arranged on the side of the substrate 1 facing away from the inhalation side 11 (also referred to as being arranged on the front of the atomization core). The substrate 1 also includes a plurality of through holes 13, which are distributed in a lattice shape on the surface of the substrate 1. The through holes 13 are configured to pass through from the inhalation side 11 to the atomization side 12, so that the atomization substrate can flow from the inhalation side 11 to the atomization side 12 through the through holes 13, and in this process, the atomization substrate is heated and atomized by the heating element coupled to the substrate 1.

[0054] In some embodiments, the cross section of the substrate 1 perpendicular to the normal line can be rectangular, circular or any other appropriate polygon. The following mainly introduces the rectangular substrate 1. However, it should be understood that the substrates 1 with other cross sections are similar and will not be described in detail here. In some embodiments, multiple substrates 1 can be obtained by shearing a piece of profile. In some alternative embodiments, the substrates 1 can also be processed separately.

[0055] The heating element includes a heating diaphragm arranged between a pair of electrodes 2. In some embodiments, a pair of electrodes 2 are respectively arranged at both ends of the length direction of the substrate 1 and are suitable for supplying power to the heating diaphragm when the pair of electrodes 2 are energized, so that at least a portion of the heating diaphragm is heated, and the atomization matrix is ​​preheated and / or the atomization matrix is ​​atomized. The heating diaphragm is attached to at least one of the inner surfaces of the suction side 11, the atomization side 12 and the multiple through holes 13 of the atomization substrate 1. In some embodiments, the heating diaphragm is attached to the inner surfaces of the suction side 11, the atomization side 12 and the multiple through holes 13 of the substrate 1 by electroplating or the like, so that the heating diaphragm is continuously attached to the suction side 11, the atomization side 12 and the inner surfaces of the through holes 13. In this way, the heating diaphragm located on the atomization side 12 is electrically connected to the heating diaphragm located on the inner surface of the through hole 13 through the portion of the heating diaphragm located on the suction side 11.

[0056] The atomization core also includes a plurality of isolation grooves. The isolation groove is at least formed on the heating diaphragm and runs through the heating diaphragm to cut off the electrical connection of the heating diaphragms on both sides of the isolation groove, thereby separating the heating diaphragm into a plurality of regions different from the conduction state of the electrode 2. For example, some regions are in a conduction state, that is, the electrical connection between the electrode and the region can be conducted, and some regions are in a non-conducting state, that is, the electrical connection between the electrode and the corresponding region is disconnected. For example, in some embodiments, the isolation groove can separate the heating diaphragm into a first region and a second region, and during the period when a pair of electrodes 2 supply power to the heating diaphragm, the current passes through the first region to heat the first region. Due to the separation of the isolation groove, no current passes through the second region, so that the second region does not heat (that is, different from the conduction state of the electrode 2). In some embodiments, the isolation groove can be arranged to extend along the length direction or width direction of the substrate 1, and the isolation groove is arranged between adjacent rows or columns of a plurality of through holes 13 in a lattice shape.

[0057] In some embodiments, the isolation groove can also be formed on the heating film and the substrate 1 at the same time to reduce the processing accuracy of the isolation groove, and at the same time improve the stability of the isolation groove in separating different regions. In some embodiments, the isolation groove can be formed by mechanical cutting or laser cutting. In other embodiments, the isolation groove can also be formed by etching.

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

[0059] The plurality of cutting grooves include at least one pair of first grooves 3, the first grooves 3 are arranged on the suction side 11 of the substrate 1, and a predetermined distance is separated between two first grooves 3 in a pair of first grooves 3, so that a preheating zone 14 is formed between the two first grooves 3, and the heating film in the preheating zone 14 can generate heat after being energized, thereby heating the atomized matrix located on the suction side 11 of the substrate 1, thereby reducing the viscosity of the atomized matrix, so that the atomized matrix 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 a pair of first grooves 3 are arranged parallel to each other along the width direction of the substrate 1 perpendicular to the length direction.

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

[0061] In some embodiments, the isolation groove further includes at least one third groove 5, which is arranged between a pair of second grooves 4 and extends to the two second grooves 4 respectively, and the third groove 5 divides the connection area into two power supply areas 15 respectively close to a pair of electrodes 2. The heating film in the power supply area 15 is electrically connected to the corresponding electrode 2, and the heating film in the power supply area 15 is also electrically connected to the heating film in the preheating area 14 in the suction side 11 through the heating film 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 are powered on, the heating film in the preheating area 14 is electrically connected to the electrode 2 through the heating films of the two power supply areas 15 on the atomization side 12, thereby causing the heating film in the preheating area 14 to be turned on and generate heat.

[0062] In some embodiments, the isolation grooves include a pair of third grooves 5, which are arranged along the length direction of the substrate 1 and are separated by a predetermined interval, so that the pair of third grooves 5 are respectively arranged close to the corresponding electrodes 2. The pair of third grooves 5 separate the connection area into power supply areas 15 respectively 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 of the preheating area 14 through the heating films of the two power supply areas 15.

[0063] like Figure 5 and Figure 6As shown, in some embodiments, the isolation grooves include two pairs of first grooves 3 and fourth grooves 6 arranged on the suction side 11, and two pairs of second grooves 4 and two pairs of third grooves 5 arranged on 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 correspond to the two pairs of second grooves 4, and each pair of third grooves 5 is respectively 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 diaphragms in the two power supply areas 15 are coupled to a pair of electrodes 2 respectively, power can be supplied to the heating diaphragm in the preheating area 14 arranged on the suction side 11. After the heating diaphragm in the preheating area 14 is energized, the atomized matrix is ​​heated, so that the viscosity of the atomized matrix is ​​reduced after being preheated, so that it can flow more smoothly from the suction side 11 to the atomization side 12 through the through hole 13. The fourth groove 6 is arranged between the two pairs of first grooves 3, and the two ends of the fourth groove 6 extend to the two adjacent pairs of first grooves 3 respectively.

[0065] The fourth slot 6 is suitable for isolating the heating film between the two pairs of first slots 3, so that the heating film between the two adjacent pairs of first slots 3 is open circuit, so that during the period when the electrode 2 is powered, the heating film between the two adjacent pairs of first slots 3 does not work, thereby controlling the preheating effect of the heating film on the atomized substrate, and further controlling the flow speed of the atomized substrate to the atomization side 12. The heating film between the two pairs of second slots 4 on the atomization side 12, because both ends are coupled to a pair of electrodes 2 respectively, after the pair of electrodes 2 are powered, the heating film between the two pairs of second slots 4 heats up and atomizes the atomized substrate flowing to the atomization side 12 through the through hole 13.

[0066] Figure 7 The front structural schematic diagram of the atomizer core according to some other embodiments of the present disclosure is shown. Figure 8 FIG. 2 shows a schematic diagram of the back structure of the atomizer core relative to the front 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 on the suction side 11, and four pairs of second grooves 4 and four third grooves 5 arranged on the atomization side 12. The two pairs of first grooves 3 are arranged along the width direction of the substrate 1, and the four pairs of second grooves 4 are grouped in pairs, and each group of second grooves 4 is respectively aligned with a pair of first grooves 3 along the discovery direction, and two pairs of second grooves 4 in each group of second grooves 4 are arranged along the length direction of the substrate 1 and are close to a pair of electrodes 2 respectively.

[0067] The four third slots 5 are respectively arranged between the four pairs of second slots 4, and the third slots 5 extend respectively to a pair of second slots 4. Thus, the third slots 5 separate a power supply area 15 in the connection area between the pair of second slots 4, and the power supply area 15 is arranged on the side of the third slot 5 close to the corresponding electrode 2. Thus, the electrode 2 can supply power to the heating diaphragm of the preheating area 14 of the suction side 11 through the heating diaphragm of the power supply area 15.

[0068] Fig. 9 The front structural schematic diagram of the atomizer core according to some other embodiments of the present disclosure is shown. Fig.10 FIG. 2 shows a schematic diagram of the back structure of the atomizer core relative to the front according to some other embodiments of the present disclosure. Fig. 9 and Fig.10 As shown, in some embodiments, the isolation grooves include a pair of first grooves 3 arranged on the suction side 11, a pair of second grooves 4 and a third groove 5 arranged on the atomization side 12. The pair of first grooves 3 are arranged in 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 zone 14 in the middle of the substrate 1.

[0069] The third groove 5 is arranged between a pair of second grooves 4, and the two ends of the third groove 5 extend toward the two second grooves 4 respectively. The third groove 5 is suitable for dividing the connection area between a pair of second grooves 4 into two power supply areas 15. Similar to other embodiments, the heating membranes in the two power supply areas 15 are respectively coupled with the corresponding electrodes 2, so that when the electrodes 2 are connected, the heating membrane in the preheating area 14 located on the suction side 11 works under the connection of the heating membranes in the two power supply areas 15, thereby preheating the atomization matrix. On the other hand, while the heating membrane in the power supply area 15 is connected to the heating membrane in the preheating area 14, the heating membrane in the power supply area 15 itself can also generate heat, thereby atomizing the atomization matrix flowing to the atomization side 12.

[0070] Fig.11 The front structural schematic diagram of the atomizer core according to some other embodiments of the present disclosure is shown. Fig.12 FIG. 2 shows a schematic diagram of the back structure of the atomizer core relative to the front according to some other embodiments of the present disclosure. Fig.11 and Fig.12 As shown, in some embodiments, the isolation grooves include a pair of first grooves 3 and a pair of fifth grooves 7 arranged on the suction side 11, and a pair of second grooves 4 and a pair of third grooves 5 arranged on the atomization side 12. The first grooves 3 extend along the length direction of the substrate 1 and the pair of first grooves 3 are arranged at intervals along the width direction of the substrate 1. The fifth grooves 7 extend along the width direction of the substrate 1 and the pair of fifth grooves 7 are arranged along the length direction of the substrate 1.

[0071] In this way, a pair of first grooves 3 and a pair of fifth grooves 7 are connected end to end in sequence and spliced ​​into a roughly rectangular frame. The pair of first grooves 3 and the pair of fifth grooves 7 together separate the heat-conducting membrane of the atomization side 12 to form a preheating zone 14 located in the rectangular frame. Similarly, the second grooves 4 arranged on the suction side 11 extend along the length direction of the substrate 1 and the pair of second grooves 4 are arranged at intervals along the width direction of the substrate 1. The third grooves 5 extend along the width direction of the substrate 1 and the pair of third grooves 5 are arranged along the length direction of the substrate 1.

[0072] A pair of third grooves 5 is arranged between a pair of fifth grooves 7, so that the heating film of the connection area separated by the pair of third grooves 5 can be connected to the heating film of the preheating area 14 through the heating film on the inner surface of the through hole 13, so that the heating film of the preheating area 14 can work and at least heat the atomized substrate after the pair of electrodes 2 are energized. In some embodiments, the heating power of the preheating area 14 can also be appropriately increased, so that the atomized 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.
