[0002] The atomizing device is a device that atomizes the atomizing substrate. The atomizing substrate passes through the 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 substrate is atomized.
[0003] The existing atomizer cores are mostly made of porous ceramics. However, during the atomization process, harmful substances in the porous ceramics are easily carried out by the atomized smoke of the atomization matrix, thus causing certain safety hazards. Utility Model Content
[0004] In a first aspect of the present disclosure, a substrate for an atomizer core is provided. The substrate comprises: a body; and at least one through-hole area and at least one slit area, 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 area in at least one through-hole area comprises: a plurality of through-hole channels, which are formed through the body and are suitable for allowing an atomized substrate to flow from a first side of the body to a second side opposite to the first side of the body, and each slit area in at least one slit area comprises: a plurality of slit channels, which are arranged through the body and are suitable for allowing an atomized substrate to flow from a first side of the body to a second side, and the cross-sectional shape of each of the plurality of slit channels is slit-shaped.
[0005] In some embodiments, each of the plurality of slot channels is formed by a waist-shaped 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 the one slit region is disposed between the two through-hole regions.
[0007] In some embodiments, a length direction of a cross section of the slit channel and a length direction of the body have an included angle of a predetermined angle.
[0008] In some embodiments, each through-via channel of the plurality of through-via channels has a diameter in the range of 10-300 μm.
[0009] In some embodiments, a pitch between adjacent through-via channels in the plurality of through-via 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-sectional shape 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 opening 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 speed of the atomized matrix in the substrate can be more accurately controlled, the conveying speed and liquid supply capacity of the atomized matrix can be ensured, the dry burning of the atomized surface can be reduced, and the atomization device can have a higher atomization amount. In addition, since the width of the slit is narrow, the occurrence of liquid leakage can also be reduced.

The atomizer core comprises: a substrate provided according to 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 atomizing matrix to atomize the atomizing matrix after power is supplied; and a pair of heating electrodes, respectively arranged at both ends of the body of the substrate in a length direction and coupled to the heating film.

[0022] 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.

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 terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.
[0025] As briefly mentioned above, when the atomizer core is made of porous ceramic material, it is easy for the harmful substances inside the porous ceramic to be easily released to the outside along with the atomized smoke. When the user inhales the atomized smoke, it is easy to inhale the harmful substances in the porous ceramic together, thus creating certain safety hazards.
[0026] There are also some prior arts that use atomizer cores made of dense materials such as glass, and allow the atomized matrix to flow through the atomizer core through a plurality of circular holes arranged in an array formed on the atomizer core. Although such an atomizer core is safer than an atomizer core made of porous ceramic material, it is difficult to accurately control the speed at which the atomized matrix passes through the atomizer core. If the diameter of the circular hole is small, the liquid flow rate of the atomized matrix cannot be guaranteed, making the atomizer device prone to dry burning due to insufficient liquid supply. If the diameter of the circular hole is large, there is a risk of leakage.
[0027] According to the present disclosure, a substrate for an atomizer core, an atomizer core and an atomizer device are provided to solve or at least partially solve the above-mentioned problems and other potential problems existing in the traditional solution. According to the embodiment of the present disclosure, by opening 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 speed of the atomized matrix on the substrate can be more accurately controlled. In this way, the conveying speed and liquid supply capacity of the atomized matrix can be reliably guaranteed, the dry burning of the atomization surface can be reduced, and the atomizer device has a higher atomization volume (TPM). In addition, due to the narrow width of the slit, the occurrence of liquid leakage can also be reduced.
[0028] Figure 1 The overall structure schematic diagram of the substrate used for the atomizer core in the embodiment of the present disclosure is shown. Figure 1 As shown, the atomizer core of the embodiment of the present disclosure generally includes: a substrate, a heating film 2 arranged on one side of the substrate, and a pair of heating electrodes 3 respectively arranged at both ends of the length direction of the substrate. The heating film 2 can be formed on the surface of the body 1 by a method 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, thereby realizing the atomization process of the atomization device.
[0029] Figure 2A , Figure 2B , Figure 3A , Figure 3B 1 and 2 show front views of substrates in some embodiments of the present disclosure. FIG. 2A to FIG. 3B As shown, the substrate includes a body 1, at least one through-hole area 11 and at least one slit area 12 arranged on the body 1. 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 run through two 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 run through two opposite sides of the body 1. The through-hole channels 111 and the slit channels 121 can allow the atomized substrate to flow from the side of the body 1 away from the heating film (also referred to as the first side of the body 1) through the through-hole channels 111 (or the slit channels 121) to the side of the body 1 coupled with the heating film (also referred to as the second side of the body 1). After the atomized substrate 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 a circle or any other appropriate polygon.
[0031] 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.
[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 a waist-shaped hole. The waist-shaped hole in this article refers to a hole with arcs at both ends of the extension direction and parallel lines in the middle for the cross-sectional shape. For example, the arcs at both ends can be semicircular. 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 elliptical, rectangular, etc.
[0033] In some embodiments, the length of the cross section of each slit channel 121 may be in the range of 10-3000 μm. In other embodiments, the width of the cross section of each slit channel 121 may be in the range of 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 may be 50 μm, and the width may be 10 μm. Thus, not only the speed at which the atomized matrix flows through the body 1 is accelerated, but also the leakage of the atomized 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 a triangle, a square, a regular hexagon, 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 spacing of adjacent through-hole channels 111 can be in the range of 10-300 μm. It should be understood that the hole spacing between adjacent through-hole channels 111 should be greater than the radius and of the corresponding two through-hole channels 111, thereby ensuring the integrity of the through-hole channel 111, thereby avoiding the situation where the through-hole channel 111 is too large due to the overlap of the two through-hole channels 111, and causing the leakage of the atomized matrix.
[0035] In some embodiments, a predetermined angle is left between the length direction of the cross section of the slit channel 121 and the length direction of the body 1. For example, the length direction of the cross section of the slit channel 121 and the length direction of the body 1 have an angle of 0°, 30°, 45°, 60°, 90°, etc. Figure 2A and Figure 3A In 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°. Figure 2B and Figure 3B In 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 90°.
[0036] In some other embodiments, the angle between the length direction of the cross section of each of the multiple slit channels 121 in the slit area 12 and the length direction of the body 1 may be the same (that is, the length directions of the cross sections of each of the multiple slit channels 121 may be parallel), or may be staggered at a predetermined angle (the length directions of the cross sections of each of the multiple 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 in the slit area 12 has an angle of 0° with the length direction of the body 1. The length direction of the cross section of another portion of the slit channels 121 has an angle of 90° with the length 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 be different.
[0038] In some embodiments, the plurality of through-hole channels 111 in each through-hole region 11 are evenly distributed inside the through-hole region 11. That is, the hole spacing between any two adjacent through-hole channels 111 in the through-hole region 11 is equal. In some other embodiments, the hole spacing between any two adjacent through-hole channels 111 in each through-hole region 11 may also be unequal. For example, in some embodiments, the hole spacing between adjacent through-hole channels 111 gradually increases from the middle of the body 1 to both ends in the length direction.
[0039] In some embodiments, the plurality of through-hole channels 111 in 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 in the through-hole region 11 may also be distributed in a regular triangle lattice or a regular hexagonal matrix.
[0040] like Figure 2A , Figure 2B As shown, in some embodiments, at least one slit area 12 includes one slit area 12, and at least one through hole area 11 includes two through hole areas 11. One slit area 12 and two through hole areas 11 are arranged along the length direction of the body 1, and one slit area 12 is located between the two through hole areas 11. In this arrangement, the slit channel 121 is located in the middle of the length direction of the body 1, and the amount of liquid in the middle area of the body 1 is the largest, which is conducive to balancing the excessively high temperature caused by the slower heat dissipation of the middle area relative to the periphery, so that the temperature of the entire atomization surface is more uniform as a whole.
[0041] like Figure 3A , Figure 3B As shown, in some other embodiments, at least one slit area 12 includes two slit areas 12, at least one through hole area 11 includes one through hole area 11, the two slit areas 12 and one through hole area 11 are arranged along the length direction of the body 1, and one through hole area 11 is located between the two slit areas 12.
[0042] In some embodiments, at least one slit area 12 and at least one through hole area 11 may be alternately arranged along the length direction or width direction of the body 1. In some alternative embodiments, the arrangement direction of at least one slit area 12 and at least one through hole area 11 may also leave a predetermined angle with the length direction or width direction of the body 1.

Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described implementations. The selection of terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the various implementations disclosed herein.
