Abstract
Description
Technical Field
[0001] Example embodiments of the present disclosure generally relate to the field of atomizing devices, and particularly to substrates for atomizing cores, atomizing cores, and atomizing devices. Background Art
[0002] An atomizing device is a device that atomizes an atomizing matrix. The atomizing matrix passes through a porous atomizing core in the atomizing device and is heated by a heating device (such as a resistance wire, etc.) in the atomizing core, so that the atomizing matrix is atomized.
[0003] Existing atomizing cores mostly use porous ceramics. However, during the atomizing process, harmful substances in the porous ceramics are easily carried out by the atomized smoke of the atomizing matrix, thus causing certain potential safety hazards. Summary of the Invention
[0004] In a first aspect of the present disclosure, a substrate for an atomizing core is provided. The substrate includes: a body; and at least one through-hole region and at least one slit region, which are arranged to be alternately arranged on the surface of the body at least along the length direction or the width direction of the body; wherein each through-hole region in the at least one through-hole region includes: a plurality of through-hole channels, which are formed through the body and are adapted to allow the atomizing matrix to flow from a first side of the body to a second side opposite to the first side of the body, and each slit region in the at least one slit region includes: a plurality of slit channels, which are arranged through the body and are adapted to allow the atomizing matrix to flow from the first side of the body to the second side, and the cross-sectional shape of each slit channel in the plurality of slit channels is in a slit shape.
[0005] In some embodiments, each slit channel in the plurality of slit channels is formed by an oval hole.
[0006] In some embodiments, the at least one through-hole region includes two through-hole regions, and the at least one slit region includes one slit region, and one slit region is arranged between the two through-hole regions.
[0007] In some embodiments, there is an included angle with a predetermined angle between the length direction of the cross-section of the slit channel and the length direction of the body.
[0008] In some embodiments, the diameter of each through-hole channel in the plurality of through-hole channels is in the range of 10 - 300 μm.
[0009] In some embodiments, the hole pitch between adjacent through-hole channels in the plurality of through-hole channels is in the range of 10 - 300 μm.
[0010] In some embodiments, the length of the cross-sectional shape of the slit channel is in the range of 10 - 3000 μm; and / or the width of the cross-section of the slit channel is in the range of 10 - 300 μm.
[0011] In some embodiments, the substrate is made of any one of single-crystal material, polycrystalline material, glass, and dense ceramic.
[0012] By forming a plurality of through-hole channels and a plurality of slit channels in the body of the substrate and adjusting the positions of the plurality of through-hole channels and the plurality of slit channels on the body, the flow rate of the atomization matrix in the substrate can be more accurately controlled, ensuring the delivery rate and liquid supply capacity of the atomization matrix, reducing the dry burning of the atomization surface, and enabling the atomization device to have a higher atomization amount. In addition, since the width of the slit is narrow, the occurrence of liquid leakage can also be reduced.
[0013] In a second aspect of the present disclosure, an atomization core is provided. The atomization core includes: a substrate provided according to the first aspect of the present disclosure; a heating film coupled to a second side of the body of the substrate and adapted to heat the atomization matrix to atomize the atomization matrix after being energized; and a pair of heating electrodes respectively disposed at two ends of the body of the substrate in the length direction and coupled to the heating film.
[0014] In a third aspect of the present disclosure, an atomization device is provided. The atomization device includes: the atomization core provided according to the second aspect of the present disclosure.

[0022] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.
[0023] It should be noted that the titles of any sections / subsections provided herein are not restrictive. Various embodiments are described throughout this document, and any type of embodiment can be included under any section / subsection. In addition, the embodiments described in any section / subsection can be combined with any other embodiments described in the same section / subsection and / or different sections / subsections in any manner.
[0024] In the description of the embodiments of the present disclosure, the term "comprising" and its like terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "an embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". There may also be other explicit and implicit definitions hereinafter. The terms "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions hereinafter.
[0025] As briefly mentioned above, when the atomizing core made of porous ceramic material works, harmful substances inside the porous ceramic are likely to be emitted to the outside along with the atomized smoke. When the user inhales the atomized smoke, the harmful substances in the porous ceramic are easily inhaled together, thus posing a certain safety hazard.
[0026] There are also some atomizing cores made of dense materials such as glass in the prior art, and multiple circular holes arranged in an array formed on the atomizing core are used to allow the atomizing matrix to flow through the atomizing core. Such an atomizing core has higher safety compared to the atomizing core made of porous ceramic material, but it is difficult to accurately control the speed of the atomizing matrix passing through the atomizing core. If the diameter of the circular hole is small, the downward liquid supply speed of the atomizing matrix cannot be guaranteed, making the atomizing device prone to dry burning due to insufficient liquid supply. If the diameter of the circular hole is large, there is a risk of liquid leakage.
[0027] A substrate for an atomization core, an atomization core, and an atomization device provided according to the present disclosure are used to solve or at least partially solve the above-mentioned problems and other potential problems existing in the traditional solutions. According to an embodiment of the present disclosure, by forming a plurality of through-hole channels and a plurality of slit channels on the body of the substrate and adjusting the positions of the plurality of through-hole channels and the plurality of slit channels on the body, the flow rate of the atomization matrix on the substrate can be controlled more accurately. In this way, the delivery rate and liquid supply capacity of the atomization matrix can be reliably ensured, the dry burning of the atomization surface can be reduced, and the atomization device has a higher atomization amount (TPM). In addition, since the width of the slit is relatively narrow, the occurrence of liquid leakage can also be reduced.
[0028] Figure 1 FIG. shows a schematic diagram of the overall structure of a substrate for an atomization core according to an embodiment of the present disclosure. As Figure 1 shown, the atomization core according to an embodiment of the present disclosure generally includes: a substrate, a heating film 2 disposed on one side of the substrate, and a pair of heating electrodes 3 respectively disposed at both ends in the length direction of the substrate. The heating film 2 can be formed on the surface of the body 1 by means such as sputtering. The heating electrode 3 is used to apply a voltage to both ends of the heating film 2. The heating film 2 generates heat under the action of the voltage applied by the heating electrode 3, thereby heating the atomization matrix, and thus realizing the atomization process of the atomization device.
[0029] Figure 2A 、 Figure 2B 、 Figure 3A 、 Figure 3B FIGS. respectively show front views of the substrate in some embodiments of the present disclosure. As Figures 2A to 3B shown, the substrate includes a body 1, at least one through-hole area 11 disposed on the body 1, and at least one slit area 12. Each through-hole area 11 in the at least one through-hole area 11 includes a plurality of through-hole channels 111. The through-hole channels 111 penetrate through opposite sides of the body 1. Similarly, each slit area 12 in the at least one slit area 12 includes a plurality of slit channels 121. The slit channels 121 also penetrate through opposite sides of the body 1. The through-hole channels 111 and the slit channels 121 can enable the atomization matrix to flow from the side of the body 1 facing away from the heating film (also referred to as the first side of the body 1) to the side of the body 1 coupled with the heating film (also referred to as the second side of the body 1) through the through-hole channels 111 (or the slit channels 121). After the atomization matrix flows from the first side of the body 1 to the second side of the body 1, it is heated by the heating film and atomized.
[0030] In some embodiments, the body 1 may be a rectangular plate-like structure. For example, the body 1 may be a rectangle with a length of 6 mm and a width of 3 mm. In some alternative embodiments, the body 1 may also be circular or any other appropriate polygon.
[0031] The body 1 can be prepared from a dense material by cutting, grinding, etc. For example, in some embodiments, the body 1 can be made of glass. In some alternative embodiments, the body 1 can also be made of single-crystal materials, polycrystal materials, or dense ceramic materials, etc.
[0032] The cross-section of each slit channel 121 perpendicular to the axis is slit-shaped or strip-shaped. For example, in some embodiments, the slit channel 121 can be formed by an oval hole. The oval hole herein refers to a hole whose two ends in the extending direction are arc-shaped and the middle is a parallel line for the cross-sectional shape. For example, the two ends of the arc can be semi-circular. In some alternative embodiments, the arcs at both ends can also be arcs formed by connecting multiple straight lines or curves. In some alternative embodiments, the cross-section of the slit channel 121 can also be oval, rectangular, etc.
[0033] In some embodiments, the length of the cross-section of each slit channel 121 can be in the range of 10 - 3000 μm. In some other embodiments, the width of the cross-section of each slit channel 121 can be within 10 - 300 μm. In some embodiments, the length of the cross-section of the slit channel 121 is greater than the width of the cross-section. For example, the length of the cross-section of the slit channel 121 can be 50 μm and the width can be 10 μm. Thus, not only the speed of the atomization matrix flowing through the body 1 is increased, but also the leakage of the atomization matrix is reduced due to the narrow width of the slit.
[0034] In some embodiments, the cross-section (hereinafter also referred to as the cross-section) of the through-hole channel 111 perpendicular to the axis can be circular. In some alternative embodiments, the cross-section of the through-hole channel 111 can also be triangular, square, regular hexagonal, etc. In some embodiments, when the cross-section of the through-hole channel 111 is circular, the aperture of the through-hole channel 111 is in the range of 10 - 300 μm. In some other embodiments, the hole pitch between adjacent through-hole channels 111 can be in the range of 10 - 300 μm. It should be understood that the hole pitch between adjacent through-hole channels 111 should be greater than the sum of the radii of the two corresponding through-hole channels 111, so as to ensure the integrity of the through-hole channel 111 and avoid the situation that the through-hole channel 111 becomes too large due to the overlap of two through-hole channels 111, resulting in the leakage of the atomization matrix.
[0035] In some embodiments, there is a predetermined angle between the length direction of the cross-section of the slit channel 121 and the length direction of the body 1. For example, the angle between the length direction of the cross-section of the slit channel 121 and the length direction of the body 1 is 0°, 30°, 45°, 60°, 90°, etc. For example, in Figure 2A and Figure 3A the example shown, the angle between the length direction of the cross-section of the slit channel 121 and the length direction of the body 1 is 0°. InFigure 2B and Figure 3B In the example shown, the angle between the longitudinal direction of the cross-section of the slit channel 121 and the longitudinal direction of the body 1 is 90°.
[0036] In some other embodiments, the included angle between the longitudinal direction of the cross-section of each of the plurality of slit channels 121 in the slit region 12 and the longitudinal direction of the body 1 may be the same (that is, the longitudinal directions of the cross-sections of the plurality of slit channels 121 may be parallel), or may be staggered by a predetermined angle (the longitudinal directions of the cross-sections of the plurality of slit channels 121 are not parallel). For example, in some embodiments, the longitudinal direction of the cross-section of a part of the slit channels 121 in the slit region 12 has an included angle of 0° with the longitudinal direction of the body 1. The longitudinal direction of the cross-section of another part of the slit channels 121 has an included angle of 90° with the longitudinal direction of the body 1.
[0037] In some embodiments, the apertures of the plurality of through-hole channels 111 in each through-hole region 11 may be the same, and in some other embodiments, the apertures of the plurality of through-hole channels 111 in the through-hole region 11 may also be different.
[0038] In some embodiments, the plurality of through-hole channels 111 in each through-hole region 11 are uniformly distributed inside the through-hole region 11. That is, the hole pitch between any two adjacent through-hole channels 111 in the through-hole region 11 is equal. In some other embodiments, the hole pitch between two adjacent through-hole channels 111 in each through-hole region 11 may also be unequal. For example, in some embodiments, the hole pitch of the adjacent through-hole channels 111 gradually increases from the middle of the body 1 to both ends in the longitudinal direction.
[0039] In some embodiments, the plurality of through-hole channels 111 in the through-hole region 11 are distributed inside the through-hole region 11 in a rectangular dot matrix manner. In some other embodiments, the plurality of through-hole channels 111 in the through-hole region 11 may also be distributed inside the through-hole region 11 in a regular triangular dot matrix or a regular hexagonal matrix, etc.
[0040] As Figure 2A , Figure 2B shown, in some embodiments, at least one slit region 12 includes one slit region 12, and at least one through-hole region 11 includes two through-hole regions 11. One slit region 12 and two through-hole regions 11 are arranged along the longitudinal direction of the body 1, and one slit region 12 is located between the two through-hole regions 11. In this arrangement, the slit channel 121 is located in the middle of the longitudinal direction of the body 1, and at the same time, the liquid flow rate in the middle region of the body 1 is the largest, which is beneficial to balancing the excessively high temperature caused by the relatively slow heat dissipation in the middle region compared with the surrounding areas, so that the temperature of the entire atomization surface is more uniform as a whole.
[0041] AsFigure 3A , Figure 3B As shown in Figure 3B , in some other embodiments, at least one slit region 12 includes two slit regions 12, at least one through-hole region 11 includes one through-hole region 11, the two slit regions 12 and the one through-hole region 11 are arranged along the length direction of the body 1, and the one through-hole region 11 is located between the two slit regions 12.
[0042] In some embodiments, at least one slit region 12 and at least one through-hole region 11 may be alternately arranged along the length direction or the width direction of the body 1. In some alternative embodiments, the arrangement direction of at least one slit region 12 and at least one through-hole region 11 may also have a predetermined angle with the length direction or the width direction of the body 1.
[0043] The various implementations of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed implementations. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described implementations. The selection of the terms used herein is intended to best explain the principles of the implementations, the practical application, or the improvement of the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the various implementation manners disclosed herein.
