[0048] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the atomizing core 100 in existing related technologies. Figure 1 The heating mesh is set in a planar shape on one side of the ceramic substrate 1. Due to the limited area of the heating mesh, the atomization area on the atomizing core 100 is small, which in turn affects the atomization efficiency of the atomizing device.
[0049] Please see Figures 2-4 , Figure 2 This is a schematic diagram of the structure of the atomizing core 100 provided in the embodiments of this application. Figure 3 This is a schematic diagram of the structure of the substrate 1 provided in an embodiment of this application. Figure 3 This is a front view schematic diagram of the atomizing core 100 provided in an embodiment of this application. For ease of description below, the following orientations are defined: the atomizing core 100 can be calibrated using the following three mutually perpendicular axes: the X-axis, the Y-axis, and the Z-axis. Wherein, as... Figure 2 As shown, the X-axis is defined as the width direction of the atomizing core 100, the Y-axis is defined as the length direction of the atomizing core 100, and the Z-axis is defined as the height direction of the atomizing core 100.
[0050] Please see Figure 2 The atomizing core 100 in this embodiment includes a substrate 1 and a heating element 2. The substrate 1 includes a first side 11 and a second side 12 facing each other. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 The diagram illustrates a first side surface 11 and a second side surface 12 arranged opposite each other along the Z-axis. A heating groove 13 recessed towards the second side surface 12 is formed on the first side surface 11. (See also...) Figure 2 The heating element 2 is installed in the heating tank 13 and the shape of the heating element 2 matches the shape of the heating tank 13.
[0051] In one example, see Figure 3 The heating tank 13 is along the first direction (i.e. Figure 3 The heating groove 13 extends along the Y-axis direction, and the two ends of the extension direction of the heating groove 13 are respectively connected to the end face of the corresponding side of the base 1. The heating element 2 is installed on the groove surface of the heating groove 13, which can be understood as the heating element 2 covering the groove surface of the heating groove 13.
[0052] In this embodiment, the shape of the heating element 2 matches the shape of the heating groove 13. This can be understood as the shape of the heating element 2 being bent being exactly the same as the shape of the heating groove 13, or the shape of the heating element 2 being bent being approximately the same as the shape of the heating groove 13.
[0053] In one example, the heating groove 13 is located along a cross-section perpendicular to the first direction (i.e., Figure 3 The shape of the cross section (parallel to XOZ) is square or trapezoidal, etc.
[0054] In one example, the cross-sectional shape of the heating groove 13 along the direction perpendicular to the first direction is at least partially arc-shaped. That is, it can be understood that the cross-sectional shape of the heating groove 13 can be partially arc-shaped, or the cross-sectional shape of the heating groove 13 can be entirely arc-shaped.
[0055] In one example, the cross-sectional shape of the heating groove 13 is an arc, a U-shaped arc, or a wave shape composed of multiple arcs. It is worth noting that the arc shape, the U-shaped arc, and the wave shape composed of multiple arcs can all be referred to as the arc shape mentioned in the embodiments of this application.
[0056] In one example, when the cross-sectional shape of the heating tank 13 is arc-shaped, the cross-sectional shape of the heating tank 13 is a dominant arc shape, a minor arc shape, or a semi-circular arc shape. Here, a dominant arc refers to an arc with a central angle greater than 180°, a minor arc refers to an arc with a central angle less than 180°, and a semi-circular arc refers to an arc with a central angle equal to 180°.
[0057] It is worth noting that when the cross-sectional shape of the heating groove 13 is square or trapezoidal, the heating element 2 is formed in a square or trapezoidal shape because its shape matches the shape of the heating groove 13. For the square or trapezoidal heating element 2, the stress at the bending part of the heating element 2 is large, and improper bending can easily damage the heating element 2. When the cross-sectional shape of the heating groove 13 is arc-shaped, the heating element 2 is not easily damaged when bending.
[0058] In one example, the substrate 1 is made of porous ceramic material; in other examples, the substrate 1 is made of porous fiber material.
[0059] In one example, the base 1 is cast, and the heating element 2 is fixed on the base 1 during the casting process.
[0060] In one example, the atomizing core 100 also includes a pin 3 connected to the heating element 2; see [link to relevant documentation]. Figure 2 The diagram illustrates two pins 3 connected to the heating element 2. Pins 3 are used for electrical connection to the power supply. When current flows through the heating element 2, the heating element 2 converts electrical energy into heat energy, causing the heating element 2 to heat up. In other examples, an electrical connection plate is provided on the first side 11 of the substrate 1. The two electrical connection plates are respectively connected to the two ends of the heating element 2 along the bending direction. The two electrodes of the atomizing device abut against the electrical connection plates to realize the electrical connection between the atomizing core 100 and the power supply.
[0061] In one example, the heating element 2 is a heating mesh, wherein the heating mesh is a mesh structure formed by heating wires through weaving, winding or welding.
[0062] When the atomizing core 100 provided in this embodiment is applied to an atomizer, the aerosol matrix in the atomizer can seep into and flow to the heating element 2 through the second side 12. The heating element 2 heats the aerosol matrix, causing it to evaporate. The heating element 2 is placed in the heating groove 13, which can increase the area of the heating element 2. The larger the area of the heating element 2, the larger the contact area with the heated object, and the more heat is transferred per unit time, thereby accelerating the evaporation of the aerosol matrix.
[0063] In this embodiment, by setting a heating groove 13 on the substrate 1, installing the heating element 2 in the heating groove 13 and setting the shape of the heating element 2 to match the shape of the heating groove 13, the area of the heating element 2 can be increased, thereby increasing the heating speed of the atomizing core 100 and improving the atomization efficiency of the atomizing device.
[0064] Regarding the shape of the second side surface 12 of the substrate 1, in one embodiment, please refer to... Figure 2 The second side 12 of the substrate 1 is a plane. It is worth noting that the plane mentioned in this embodiment is relative to the current technological level, rather than an absolute and strict definition in a mathematical sense. The plane mentioned in this embodiment is allowed to have a small deviation and can be approximately plane.
[0065] In this embodiment, by setting the second side 12 of the substrate 1 to be a plane, the structure of the substrate 1 is simplified; when the substrate 1 is formed by casting, casting the planar second side 12 also helps to simplify the structure of the casting mold.
[0066] Regarding the shape of the second side surface 12 of the substrate 1, in one embodiment, please refer to... Figure 5 , Figure 7 as well as Figure 9 The second side surface 12 of the substrate 1 has protrusions and / or depressions, which can be understood as the second side surface 12 of the substrate 1 being non-planar. For example, the second side surface 12 is wavy or trapezoidal, etc. It is worth noting that the second side surface 12 of the substrate 1 is set to be non-planar in this embodiment, mainly from two perspectives: first, to increase the area of the second side surface 12; and second, to minimize the distance between the second side surface 12 and the first side surface 11.
[0067] Regarding increasing the area of the second side 12, as mentioned above, the aerosol matrix in the atomizer can penetrate through the second side 12 and flow to the heating element 2. The larger the area of the second side 12, the greater the contact area with the aerosol matrix, which in turn helps to increase the oil guiding speed of the substrate 1 and improve the atomization efficiency of the atomizing device.
[0068] In order to reduce the distance between the second side 12 and the first side 11, the aerosol matrix in the atomizer penetrates through the second side 12, passes through the substrate 1, and reaches the heating element 2. When the distance between the second side 12 and the first side 11 is reduced, it is beneficial to reduce the travel of the aerosol matrix in the substrate 1, which in turn is beneficial to improve the oil guiding speed of the substrate 1.
[0069] It is worth noting that reducing the distance between the second side 12 and the first side 11 refers to the case where the second side 12 is planar. In some examples, by setting the second side 12 to be non-planar, the distance between a portion of the second side 12 and the first side 11 can be reduced.
[0070] When the second side 12 is designed to be non-planar, its area is usually increased compared to the case where the second side 12 is planar. Therefore, when the second side 12 of the base 1 is designed to be non-planar, the shape of the second side 12 can be set to only increase the area of the second side 12, or the shape of the second side 12 can be set to simultaneously increase the area of the second side 12 and decrease the distance between the second side 12 and the first side 11.
[0071] In this embodiment, by setting the second side 12 of the substrate 1 to be non-planar, the atomization efficiency of the atomizing device is improved.
[0072] In one embodiment, please refer to Figure 5 and Figure 6 The second side surface 12 of the substrate 1 is an arc surface.
[0073] A circular arc surface refers to a curved surface formed by moving along a specific path (such as a straight line or circle) or rotating about an axis, using a circular arc as its generatrix. See also... Figure 5 This illustrates that the second side 12 extends in a direction parallel to the Y-axis. Of course, the second side 12 can also be set to extend in a direction parallel to the X-axis.
[0074] In one example, the cross-section of the second side 12 (referring to the cross-section parallel to) Figure 5 The cross-section of ZOX is semi-circular, inferior arc, or superior arc.
[0075] In one example, see Figure 5 Along the extension direction perpendicular to the heating tank 13 (i.e. Figure 5 (in the direction of the X-axis), the middle region of the second side 12 protrudes in a direction away from the first side 11.
[0076] In this embodiment, by setting the second side surface 12 as an arc surface, compared with the case where the second side surface 12 is a plane, the area of the second side surface 12 can be increased, which is conducive to improving the oil guiding speed of the substrate 1; when the substrate 1 is formed by casting, casting the arc-shaped second side surface 12 is also conducive to simplifying the structure of the casting mold.
[0077] In one embodiment, the second side surface 12 is an arc surface, and along the extension direction perpendicular to the heating groove 13, the central region of the second side surface 12 is recessed towards the first side surface 11.
[0078] In this embodiment, by setting the second side surface 12 as an arc surface, compared to the case where the second side surface 12 is flat, the area of the second side surface 12 can be increased, thereby improving the oil guiding speed of the substrate 1; by setting the second side surface 12 to be concave towards the first side surface 11, the distance between the second side surface 12 and the first side surface 11 can be reduced, further improving the oil guiding speed of the substrate 1; when the substrate 1 is formed by casting, casting the arc-shaped second side surface 12 also helps to simplify the structure of the casting mold.
[0079] In one embodiment, please refer to Figure 7 and Figure 9 A groove 14 is formed on the second side 12 that is recessed toward the first side 11.
[0080] In one example, see Figure 7 The second side surface 12 is a plane, that is, a groove 14 is provided on the planar second side surface 12; in other examples, please refer to Figure 9 The second side surface 12 is an arc surface, that is, a groove 14 can be provided on the arc-shaped second side surface 12.
[0081] In one example, see Figure 7 and Figure 9 In some examples, there is one groove 14; in others, multiple non-connected grooves 14 are provided on the second side 12.
[0082] In one example, the bottom surface of the groove 14 is a plane; in other examples, protrusions and / or depressions are formed on the bottom surface of the groove 14, that is, the bottom surface of the groove 14 is not a plane.
[0083] In one example, the groove 14 may be shaped as a direction, a circle, a trapezoid, or so on.
[0084] In this embodiment, by providing a groove 14 recessed towards the first side 11 on the second side 12, the distance between the bottom surface of the groove 14 and the first side 11 is reduced, which can help reduce the travel of the aerosol matrix in the substrate 1, thereby helping to improve the oil guiding speed of the substrate 1.
[0085] In one embodiment, a pin 3 is connected to the heating element 2, and the pin 3 is at least partially embedded in the substrate 1.
[0086] In one example, the heating element 2 includes an inner side and an outer side. The outer side of the heating element is connected to the heating groove 13. The pins 3 are disposed on the outer side of the heating element 2. The two pins 3 are respectively close to the two ends of the heating element 2 along the bending direction. Due to the positional relationship between the heating element 2, the base 1, and the pins 3, the pins 3 can be at least partially embedded in the base 1.
[0087] In this embodiment, by setting the pin 3 to be at least partially embedded in the substrate 1, it is beneficial for the pin 3 to be stably fixed on the heating element 2.
[0088] In one embodiment, please refer to Figure 2 , Figure 5 , Figure 7 as well as Figure 9 The extension direction of the portion of pin 3 exposed outside the substrate 1 is parallel to the extension direction of the heating element 2, wherein the extension direction of the heating element 2 is along the X-axis direction in the figure; or, please refer to Figure 11 The portion of pin 3 exposed outside the substrate 1 is bent in a direction away from the substrate 1.
[0089] In one example, see Figure 12 Pin 3 includes a first segment 31 and a second segment 32. One end of the first segment 31 is connected to the second segment 32. The first segment 31 is connected to the heating element 2 and is located inside the base 1. The first segment 31 and the second segment 32 can be configured to be in a straight line, or, see [link to relevant documentation]. Figure 12 An angle can be set between the first segment 31 and the second segment 32, for example, the angle between the first segment 31 and the second segment 32 is about 90°.
[0090] In this embodiment, when the extension direction of the portion of the pin 3 protruding from the substrate 1 is parallel to the extension direction of the heating element 2, it is convenient for the atomizing core 100 to be connected to the electrode located on its horizontal side; when the pin 3 is bent away from the substrate 1, it is convenient for the atomizing core 100 to be connected to the electrode located below it.
[0091] In one embodiment, please refer to Figure 10 A portion of the first side 11 is recessed toward the second side 12 to form a stepped structure 112, and one end of the pin 3 protrudes through the stepped structure 112.
[0092] In one example, see Figure 11The first side surface 11 includes two side regions 111, which are located on both sides of the heating tank 13. The side regions 111 include a first region 1111, a second region 1112, and a third region 1113. The first region 1111 and the second region 1112 are along a first direction. Figure 11 The components are arranged sequentially along the Y-axis. The third region 1113 connects the first region 1111 and the second region 1112. The second region 1112 is recessed towards the second side surface 12. This means that, when the second side surface 12 is planar, the distance between the second region 1112 and the second side surface 12 is less than the distance between the first region 1111 and the second side surface 12, creating a stepped structure 112 on the side surface 111. The pin 3 passes through the third region 1113 and exits the substrate 1. In other embodiments, the side surface 111 is planar, meaning the stepped structure 112 is not provided on the side surface 111, and the two pins 3 pass through the end face of the substrate 1.
[0093] Please see Figure 12 A notch 21 is provided on the heating element 2 to accommodate the recess of the second region 1112 toward the second side 12, so that the heating element 2 fits the groove surface of the heating groove 13 at all points.
