[0001] This application claims the priority to Chinese Patent Application No. 202311792502.8 filed on Dec. 22, 2023, and entitled “SUBSTRATE FOR ATOMIZING CORE, ATOMIZING CORE AND ATOMIZING APPARATUS” , which is hereby incorporated by reference in its entirety.FIELD
[0002] Example embodiments of the present disclosure generally relate to the field of atomizing apparatus, and in particular, to a substrate for an atomizing core, an atomizing core, and an atomizing apparatus.BACKGROUND
[0003] An atomizing apparatus is an apparatus for atomizing an aerosol precursor. The aerosol precursor passes through a porous atomization core in the atomizing apparatus, and is heated by a heating apparatus (such as a resistance wire) in the atomizing core, so that the aerosol precursor is atomized.
[0004] The existing atomizing core mostly uses a porous ceramic. However, in the process of atomization, harmful substances in the porous ceramic are easily carried out by the smoke after the atomization of the aerosol precursor, thereby causing a certain safety hazard.SUMMARY
[0005] In a first aspect of the present disclosure, a substrate for an atomizing core is provided. The substrate comprises: a body; at least one through-hole region and at least one slit region arranged to be alternately arranged on a surface of the body at least in a length direction or a width direction of the body ; wherein each of the at least one through-hole region comprises: a plurality of through-hole channels formed through the body and adapted to allow an aerosol precursor to flow from a first side of the body to a second side of the body opposite the first side, and each of the at least one slit region comprises: a plurality of slit channels arranged penetrating through the body and adapted to allow the aerosol precursor to flow from the first side to the second side of the body , and wherein a cross section shape of each of the plurality of slit channels is slit-shaped.
[0006] In some embodiments, each of the plurality of slit channels is formed by a waist-shaped hole.
[0007] In some embodiments, the at least one through-hole region comprises two through-hole regions , and the at least one slit region comprises one slit region , wherein the one slit region is arranged between the two through-hole regions.
[0008] In some embodiments, there is a predetermined angle formed between a length direction of the cross section of the slit channel and a length direction of the body.
[0009] In some embodiments, each of the plurality of through-hole channels has a diameter in a range of 10-300 μm.
[0010] In some embodiments, a hole distance between adjacent through-hole channels in the plurality of through-hole channels ranges from 10-300 μm.
[0011] In some embodiments, a length of the cross section shape of the slit channel is in a range of 10-3000 μm; and / or a width of the cross section shape of the slit channel is in a range of 10-300 μm.
[0012] In some embodiments, a material of the substrate is any one of a monocrystalline material, a polycrystalline material, a glass and dense ceramic.
[0013] By providing a plurality of through-hole channels and a plurality of slit channels on a body of a substrate, and adjusting positions of the plurality of through-hole channels and the plurality of slit channels on the body, a flow speed of an aerosol precursor in the substrate can be controlled more accurately, thereby ensuring a delivery speed and a liquid supply capacity of the aerosol precursor, reducing the situation of dry burning on an atomizing surface, and enabling an atomizing apparatus to have a higher Total Particulate Matter. In addition, due to the narrow width of the slit, the occurrence of aerosol precursor leakage can be reduced.
[0014] In a second aspect of the present disclosure, an atomizing core is provided. The atomizing core comprises: a substrate of the first aspect of the present disclosure; a heating film coupled to a second side of a body of the substrate and adapted to heat an aerosol precursor after being electrified to atomize the aerosol precursor; and a pair of heating electrodes respectively arranged to two ends of the body of the substrate in a length direction and coupled to the heating film.
[0015] In a third aspect of the present disclosure, an atomizing apparatus is provided. The atomizing apparatus comprises: an atomizing core of the second aspect of the present disclosure.

Other features of the present disclosure will become readily understood from the following description.BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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 may be implemented in various forms and should not be construed as limited to embodiments set forth herein, but rather, these embodiments are provided for a thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for illustrative purposes and are not intended to limit the scope of the present disclosure.
[0024] It should be noted that the headings of any section / subsection provided herein are not limiting. Various embodiments are described throughout herein, and any type of embodiment can be included under any section / subsection. Furthermore, 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.
[0025] In the description of embodiments of the present disclosure, the term "including" and the like should be understood as open-ended including, that is, "including but not limited to" . The term "based on" should be read as "based at least in part on" . The term "one embodiment" or "the embodiment" should be read as "at least one embodiment" . The term "some embodiments" should be understood as "at least some embodiments" . Other explicit and implicit definitions may also be included below. The terms "first" , "second" , etc. may refer to different or identical objects. Other explicit and implicit definitions may also be included below.
[0026] As mentioned briefly above, when the atomizing core made of the porous ceramic material operates, it is easy for the harmful substances inside the porous ceramic to be released to the outside along with the atomized smoke, and when a user inhales the atomized smoke, the harmful substances in the porous ceramic are easily sucked together, thereby producing certain safety risks.
[0027] There are also some prior art atomizing cores made of a dense material such as glass, and the aerosol precursor is allowed to flow through the atomizing core by forming a plurality of circular holes arranged in an array on the atomizing core. Such an atomizing core has higher safety than an atomizing core made of a porous ceramic material, but it is difficult to accurately control the speed at which an aerosol precursor passes through the atomizing core. If the diameter of the circular hole is relatively small, the liquid discharging speed of the aerosol precursor cannot be ensured, so that the atomization apparatus is easy to dry burning due to insufficient liquid supply. If the diameter of the circular hole is large, there is a risk of leakage.
[0028] The present disclosure provides a substrate for an atomizing core, an atomizing core, and an atomizing apparatus to solve, or at least partially solve, the described problems and other potential problems existing in the conventional solutions. According to the embodiments of the present disclosure, by providing a plurality of through-hole channels and a plurality of slit channels on a body of a substrate, and adjusting positions of the plurality of through-hole channels and the plurality of slit channels on the body, a flow speed of an aerosol precursor in the substrate can be controlled more accurately, thereby ensuring a delivery speed and a liquid supply capacity of the aerosol precursor, reducing the situation of dry burning on an atomizing surface, and enabling an atomizing apparatus to have a higher Total Particulate Matter (TPM) . In addition, due to the narrow width of the slit, the occurrence of aerosol precursor leakage can be reduced.
[0029] FIG. 1 illustrates an overall structure schematic view of a substrate for an atomizing core according to some embodiments of the present disclosure. As shown in FIG. 1, the atomizing core according to embodiments of the present disclosure generally comprises: a substrate, a heating film 2 arranged on one side of the substrate, and a pair of heating electrodes 3 respectively arranged at two ends in a length direction of the substrate. The heating film 2 can be formed on the surface of the body 1 by, for example, electroplating, and the heating electrodes 3 are used to apply a voltage to both ends of the heating film 2. The heating film 2 generates heat under the action of a voltage applied by the heating electrodes 3 so as to heat the aerosol precursor, thereby realizing the atomizing process of the atomizing apparatus.
[0030] FIGS. 2A, 2B, 3A, and 3B respectively illustrate front views of a substrate in some embodiments of the present disclosure. As shown in FIGS. 2A to 3B, the substrate comprises a body 1, at least one through-hole region 11 disposed on the body 1 and at least one slit region 12 disposed on the body 1. Each of the at least one through-hole region 11 comprises a plurality of through-hole channels 111, and the through-hole channels 111 penetrate through two opposite sides of the body 1. Similarly, each of the at least one slit region 12 comprises a plurality of slit channels 121, and the slit channels 121 also penetrate through two opposite sides of the body 1. The through-hole channel 111 and the slit channel 121 can allow the aerosol precursor to flow from a side of the body 1 facing away from the heating film 2 (also referred to as a first side of the body 1) to a side of the body 1 coupled with the heating film 2 (also referred to as a second side of the body 1) through the through-hole channel 111 (or the slit channel 121) . The aerosol precursor is heated by heating film 2 and atomized after flowing from the first side of the body 1 to the second side of the body 1.
[0031] In some embodiments, the body 1 can be a rectangular plate-like structure, for example, the body 1 can be a rectangle with a length of 6 millimeters and a width of 3 millimeters. In some alternative embodiments, the body 1 can also be circular or any other suitable polygonal shape.
[0032] The body 1 can be made of 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 a single crystal material, a polycrystalline material, or a dense ceramic material, etc.
[0033] The cross section of each of the slit channel 121 perpendicular to the axis has a slit shape or an elongated shape. For example, in some embodiments, the slit channels 121 can be formed by waist-shaped holes. The waist-shaped hole herein refers to a hole whose cross section shape is arc-shaped with two ends in an extending direction , and parallel lines in the middle. For example, the arc-shaped at the two ends can be a semicircle. In some alternative embodiments, the arc-shaped at the two ends can also be an arc-shaped formed by connecting a plurality of straight lines or curved lines. In some alternate embodiments, the cross section of the slit channels 121 can also be oval, rectangular, etc.
[0034] In some embodiments, the length of the cross section of each of the slit channels 121 can be in a range of 10-3000 μm. In other embodiments, the cross section width of each of the slit channels 121 can be in a range of 10-300 μm. In some embodiments, the length of the cross section of the slit channel 121 is longer 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 aerosol precursor flowing through the body 1 is accelerated, but also the leakage of the atomized substrate is reduced due to the narrow width of the slit.
[0035] In some embodiments, the cross section of the through-hole channel 111 perpendicular to the axis (hereinafter also referred to as cross section) can be circular. In some alternative embodiments, the cross section of the through-hole channels 111 can also be triangular, square, regular hexagon, etc. In some embodiments, if the cross section of the through-hole channel 111 is circular, the diameter of the through-hole channel 111 is in a range of 10-300 μm. In some other embodiments, the hole distance of adjacent through-hole channels 111 can be in a range of 10-300 μm.It should be understood that the hole distance between adjacent through-hole channels 111 should be greater than the sum of the radii of the two corresponding through-hole channels 111, thereby ensuring the integrity of the through-hole channels 111, so as to avoid the case where the through-hole channels 111 are excessively large due to the overlap of the two through-hole channels 111 and the aerosol precursor leaks.
[0036] In some embodiments, there is a predetermined angle formed between the length direction of the cross section of the slit channel 121 and the length direction of the body 1. For example, there are angles of 0 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, etc., between the length direction of the cross section of the slit channel 121 and the length direction of the body 1. For example, in the example shown in FIG. 2A and FIG. 3A, 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 degrees. In the examples shown in FIGS. 2B and 3B, the angle between the length direction of the cross section of the slit channel 121 and the longitudinal direction of the body 1 is 90 degrees.
[0037] In some other embodiments, an angle between a length direction of a cross section of each of the plurality of slit channels 121 in the slit region 12 and the length direction of the body 1 can be the same (that is to say, the length directions of the cross sections of the plurality of slit channels 121 can be parallel) , and can also be staggered by a predetermined angle (the length directions of the cross sections of the plurality of slit channels 121 are not parallel) . For example, in some embodiments, the length direction of the cross section of a portion of the slit channels 121 within the slit region 12 and the length direction of the body 1 have an included angle of 0℃. A length direction of a cross section of the other part of the slit channel 121 forms an angle of 90 degrees with the length direction of the body 1.
[0038] In some embodiments, the apertures of the plurality of through-hole channels 111 within each through-hole region 11 can be the same. In some other embodiments, the apertures of the plurality of through-hole channels 111 within the through-hole region 11 can also be different.
[0039] In some embodiments, the plurality of through-hole channels 111 within each through-hole region 11 are evenly distributed inside the through-hole region 11. That is to say, the hole distances between any two adjacent through-hole channels 111 in the through-hole region 11 are equal, and in some other embodiments, the hole distances between two adjacent through-hole channels 111 in each through-hole region 11 can also be different. For example, in some embodiments, the hole distance between the adjacent through-hole channels 111 is gradually increased from the middle portion to the two ends along the length direction of the body 1.
[0040] In some embodiments, the plurality of through-hole channels 111 within the through-hole region 11 are distributed in a rectangular lattice inside the through-hole region 11. In other embodiments, the plurality of through-hole channels 111 within the through-hole region 11 can also be distributed in a triangular lattice or a hexagonal lattice inside the through-hole region11.
[0041] As shown in FIG. 2A and FIG. 2B, in some embodiments, the at least one slit region 12 comprises one slit region 12, and the at least one through-hole region 11 comprises two through-hole regions 11. The one slit region 12 and the two through-hole regions 11 are arranged along the length 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 body 1 in the length direction, and at the same time, the volume of the liquid drainage in the middle of the body 1 is the maximum, which helps to balance the excessively high temperature caused by slow heat dissipation of the middle relative to the periphery, so that the temperature of the whole atomization surface is more uniform as a whole.
[0042] As shown in FIG. 3A and FIG. 3B, in some other embodiments, the at least one slit region 12 comprises two slit regions 12, the at least one through-hole region 11 comprises 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.
[0043] In some embodiments, the at least one slit region 12 and the at least one through-hole region 11 can be alternately arranged in a length direction or a width direction of the body 1. In some alternative embodiments, the arrangement direction of the at least one slit region 12 and the at least one through-hole region 11 can also have a predetermined angle with the length direction or the width direction of the body 1.
[0044] Having described implementations of the disclosure above, the foregoing description is exemplary, not exhaustive, and is not limited to the implementations disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the implementations described. The choice of terms used herein is intended to best explain the principles of the implementations, the practical application, or improvements to technologies in the marketplace, or to enable others of ordinary skill in the art to understand the implementations disclosed herein.
