[0010] Furthermore, in the atomization core liquid guide, the height of the micro groove is preferably within 0.1 mm.

[0011] Furthermore, in the atomizing core liquid-conducting liquid, it is preferred that the liquid-conducting liquid is a cylindrical structure or a plate structure.

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0032] When a component is referred to as being “fixed to” or “disposed on” another component, it may be directly or indirectly located on the other component. When a component is referred to as being “connected to” another component, it may be directly or indirectly connected to the other component.

[0033] The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution. The terms "first", "second", etc. are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0034] Embodiment 1, as Figure 1-Figure 4 As shown, an atomizing core liquid guide 2 is formed by overlapping multiple layers of liquid guide cloth 21. The liquid guide cloth 21 can be made of different materials, such as flax fiber, long-staple cotton fiber, spunlace non-woven fiber, mixed fiber, etc. At least one side of at least one layer of liquid guide cloth 21 has texture, so that at least two adjacent layers of liquid guide cloth 21 are not completely fitted to form micro grooves 22, and multiple micro grooves 22 are connected to form a liquid storage cavity. Superposition refers to spatial superposition, that is, the atomizing core liquid guiding liquid 2 is formed by stacking layers of liquid guiding cloth 21 in space; fitting refers to the contact between two objects, and there is no gap at the contact position. The texture of the present invention does not refer to the traditional pattern, but the liquid guiding cloth 21 is woven in the weaving process to form a depression or protrusion on the surface of the liquid guiding cloth 21, or some technical means are used to make the surface of the liquid guiding cloth 21 appear depressed or protruding, such as mold pressing, adjusting the textile parameter settings, extrusion and other technical means, at least one side of at least one layer of liquid guiding cloth 21 is depressed or protruded, and in the multiple layers of liquid guiding cloth 21 stacked together, due to the existence of the texture, at least two adjacent layers of liquid guiding cloth 21 are not completely The microgrooves 22 are formed by fitting together, and a plurality of microgrooves 22 are connected to form a liquid storage cavity, in which liquid is stored. The microgrooves 22 can store more liquid during actual use. A plurality of microgrooves 22 are connected to form a liquid storage cavity structure. Compared with the traditional structure of the liquid-conducting cloth 21 without microgrooves 22, the multi-layer liquid-conducting cloth 21 is provided. During the atomization process, when the liquid on the innermost liquid-conducting cloth 21 close to the heating element 3 is consumed, the liquid at other positions in the liquid-conducting cloth 21 will be transferred to the innermost liquid-conducting cloth 21 due to the capillary phenomenon. Since the position of the liquid storage cavity inside the liquid-conducting cloth 21 is closer to the oil tank outside the liquid-conducting cloth 21, the liquid stored in the liquid storage cavity can play an effect of rapid liquid supply, thereby improving the liquid conduction efficiency and optimizing the atomization effect.

[0035] The liquid-conducting fabric 21 includes at least one layer of vertical-striped liquid-conducting fabric 211 and / or at least one layer of horizontal-striped liquid-conducting fabric 212. Figure 5As shown, the vertical liquid-conducting cloth 211 is provided with lines arranged in an overall vertical direction, forming overall vertical microgrooves 22; the overall vertical arrangement means that the lines of the liquid-conducting cloth 21 as a whole extend from the upper end to the lower end, that is, the microgrooves 22 as a whole extend from the upper end to the lower end, but it is not required that each line is arranged from top to bottom, and branch lines may be extended outward on the basis of the vertical lines, or vertical lines and horizontal lines may be arranged alternately; as shown in FIG. Figure 6 As shown, the transverse liquid-conducting cloth 212 is provided with lines that are arranged in an overall transverse manner, forming an overall transverse microgroove 22. The overall transverse arrangement refers to the overall lines of the liquid-conducting cloth 21 extending from the left side to the right side, that is, the microgrooves 22 extend from the left side to the right side as a whole, but it is not required that each line is arranged from left to right, and it can also be a branch line extending outward on the basis of the transverse lines, or it can be a vertical line and a transverse line staggered arrangement. The atomizing core liquid-conducting cloth 21 composed of these two types of lines can be superimposed in a variety of ways, and can be composed of multiple layers of transverse liquid-conducting cloth 212, or multiple layers of vertical liquid-conducting cloth 211, or multiple layers of transverse liquid-conducting cloth 212 and vertical liquid-conducting cloth 211 are combined and superimposed to form.

[0036] Due to the different types of patterns of the liquid-conducting cloth 21, different microgrooves 22 can be formed through different arrangements: the vertical-striped liquid-conducting cloth 211 and the horizontal-striped liquid-conducting cloth 212 are staggered and overlapped, that is, a layer of vertical-striped liquid-conducting cloth 211 is overlapped with a layer of horizontal-striped liquid-conducting cloth 212, and they are repeatedly laminated to form a liquid-conducting body 2 with a layer of vertical microgrooves 22 and a layer of horizontal microgrooves 22, and the microgrooves 22 of each layer are connected to form a liquid storage cavity, and at this time, the liquid-conducting body 2 has multiple layers of liquid storage cavities; or half of the liquid-conducting cloth 21 in the liquid-conducting body 2 is the vertical-striped liquid-conducting cloth 211, and the other half is the horizontal-striped liquid-conducting cloth 212, that is, several layers of vertical-striped liquid-conducting cloth 211 with the same patterns are overlapped together, and several layers of horizontal-striped liquid-conducting cloth 212 with the same patterns are overlapped together, and then the two are overlapped together to form microgrooves 22 on the contact surface of the two, and at this time, the liquid-conducting body 2 has only one layer of microgrooves 22, that is, a liquid storage cavity is formed in the middle of the liquid-conducting body 2; or all of them are vertical-striped liquid-conducting cloth 211, The patterns are different or partially different. When the vertical liquid-conducting cloth 211 is overlapped, the protrusions or depressions are staggered, so that the protrusions or depressions of each layer of the vertical liquid-conducting cloth 211 do not completely overlap in radial projection, and at this time, vertical microgrooves 22 are formed. The different degrees of staggering can affect the size of the formed microgrooves 22, and further affect the size of the liquid storage cavity; or all are horizontal liquid-conducting cloth 212, the patterns are different or partially different. When the horizontal liquid-conducting cloth 212 is overlapped, the protrusions or depressions of each layer of the horizontal liquid-conducting cloth 212 are staggered, and the protrusions or depressions of each layer of the horizontal liquid-conducting cloth 212 do not completely overlap in radial projection, and at this time, horizontal microgrooves 22 are formed. The different degrees of staggering can affect the size of the formed microgrooves 22, and further affect the size of the liquid storage cavity; the size of the patterns is not limited, and the formation of the microgrooves 22 is not limited to the above-mentioned forms. The protrusions or depressions of the patterns are staggered to a certain extent to form different microgrooves 22, which will not be described in detail.

[0037] The liquid-conducting cloth 21 can be a liquid-conducting cloth 21 with texture on one side or a liquid-conducting cloth 21 with texture on both sides. Due to the difference in the structure of the liquid-conducting cloth 21, different microgrooves 22 can be formed by overlapping: one side of the liquid-conducting cloth 21 without texture is formed by laminating with one side of another liquid-conducting cloth 21 with texture, that is, a layer of liquid-conducting cloth 21 with texture on one side is repeatedly overlapped with a layer of liquid-conducting cloth 21 without texture, that is, microgrooves 22 are formed on the contact surfaces of the two liquid-conducting cloths 21, and the microgrooves 22 are connected to form a liquid storage cavity. At this time, the liquid-conducting cloth 2 has multiple layers of liquid storage cavities; or a layer of liquid-conducting cloth 21 with texture on one side is repeatedly overlapped with a layer of liquid-conducting cloth 21 with texture on both sides, at this time, the textured side of the single-layer textured liquid-conducting cloth 21 is in contact with any side of the double-layer textured liquid-conducting cloth 21, and the textures are staggered (that is, the depressions or protrusions on the surfaces of the two liquid-conducting cloths 21) The liquid guiding cloth 21 is not overlapped and pasted together), and the side without texture in the single-layer textured liquid guiding cloth 21 is in contact with any side of another double-layer textured liquid guiding cloth 21. At this time, multiple layers of microgrooves 22 can also be formed, and the microgrooves 22 are connected to form a liquid storage cavity. At this time, the liquid guiding body 2 also has multiple layers of liquid storage cavities; or half of the liquid guiding cloth 21 in the liquid guiding body 2 is single-sided textured, and the other half is double-sided textured liquid guiding cloth 21, that is, several layers of single-sided textured liquid guiding cloth 21 are overlapped together, and several layers of double-sided textured liquid guiding cloth 21 are overlapped together, and then the two are overlapped on the contact surface to form microgrooves 22. At this time, the liquid guiding body 2 has only one layer of microgrooves 22, that is, a liquid storage cavity is formed in the middle of the liquid guiding body 2; the size of the texture is not limited, and the formation of the microgrooves 22 is not limited to the above-mentioned form. The convex or concave parts of the texture are staggered to a certain extent to form different microgrooves 22, which will not be described in detail. The liquid-conducting cloth 21 is provided with 1-8 layers, the specific number of the liquid-conducting cloth 21 is not limited, and the arrangement positions of the microgrooves 22 between different layers are at least partially staggered in the radial direction. The staggered arrangement in the present application means that the microgrooves 22 formed when different layers of liquid-conducting cloth 21 are overlapped are staggered in radial position, which is not necessarily one-to-one corresponding. The different degrees of staggering can affect the size of the microgrooves 22, that is, the size of the liquid storage cavity.

[0038] The texture of the liquid-conducting cloth 21 is in consistent direction and regularly arranged, that is, the texture is a repeating unit with a certain regular arrangement, or the texture direction of the liquid-conducting cloth 21 is generally consistent. This makes it possible to use simpler technical means to achieve the desired texture when preparing the texture of the liquid-conducting cloth 21, and it is also simpler to overlap the liquid-conducting cloth 21, thereby saving production costs.

[0039] The height of the microgrooves 22 in the liquid guiding liquid 2 is within 0.1 mm. By controlling the height of the microgrooves 22 to control the size of the liquid storage cavity, the liquid guiding cloth 21 will be saturated when it absorbs liquid to a certain extent. When the liquid storage cavity is too large, the liquid guiding liquid 2 may be oversaturated, causing the liquid to overflow from the liquid guiding liquid 2, ultimately affecting the atomization effect.

[0040] like Figure 1-Figure 2 As shown, the liquid-conducting body 2 may be a cylindrical structure; Figure 3-Figure 4 According to the actual structure of the atomizer core, the liquid guide 2 can be cylindrical or plate-shaped, and its actual shape can be changed according to actual needs.

[0041] Since the formation of microgrooves is diverse, the forms of liquid storage cavities are also diverse. They can be evenly arranged on the contact surface of each layer of liquid-conducting cloth, or one liquid storage cavity can be arranged every other layer. They can be vertical or horizontal, which will not be described in detail here.

[0042] Example 1-1, as Figure 1 As shown, the liquid guiding material 2 is a tubular structure, and is formed by overlapping a horizontal liquid guiding cloth 212 and a vertical liquid guiding cloth 211, and the two liquid guiding cloths each occupy half. The inner side of the liquid guiding material 2 is the vertical liquid guiding cloth 211, and the outer side is the horizontal liquid guiding cloth 212. Micro grooves 22 are formed on the contact surface of the horizontal liquid guiding cloth 212 and the vertical liquid guiding cloth 211. Multiple micro grooves 22 are connected to form a liquid storage cavity. At this time, the liquid guiding material 2 has a layer of liquid storage cavity.

[0043] Embodiment 1-2, as Figure 2 As shown, the liquid guiding body 2 is a tubular structure, and the liquid guiding body 2 is formed by overlapping multiple layers of vertical-grained liquid guiding cloth 211. The vertical lines of each layer of vertical-grained liquid guiding cloth 211 are arranged in a staggered manner, that is, the depressions or protrusions on the surfaces of two adjacent liquid guiding cloths 21 are not overlapped and adhered together to form micro grooves 22. The micro grooves 22 of each layer are connected to form a liquid storage cavity. At this time, the liquid guiding body 2 has multiple layers of liquid storage cavities.

[0044] Embodiment 1-3, as Figure 3 As shown, the liquid guiding cloth 2 is a plate-like structure, and the liquid guiding cloth 2 is formed by overlapping a horizontal liquid guiding cloth 212 and a vertical liquid guiding cloth 211, and the two liquid guiding cloths each occupy half, the vertical liquid guiding cloth 211 has the same texture, and the horizontal liquid guiding cloth 212 has the same texture. Micro grooves 22 are formed on the contact surface between the innermost horizontal liquid guiding cloth 212 and the innermost vertical liquid guiding cloth 211, and multiple micro grooves 22 are connected to form a liquid storage cavity. At this time, the liquid guiding cloth 2 has a layer of liquid storage cavity.

[0045] Embodiment 1-4, as Figure 4 As shown, the liquid guiding device 2 is a plate-like structure, and the liquid guiding device 2 is formed by overlapping multiple layers of transverse liquid guiding cloth 212. The transverse lines of each layer of transverse liquid guiding cloth 212 are staggered, that is, the depressions or protrusions on the surfaces of two adjacent liquid guiding cloths 21 are not overlapped and adhered together to form micro grooves 22. The micro grooves 22 of each layer are connected to form a liquid storage cavity. At this time, the liquid guiding device 2 has multiple layers of liquid storage cavities.

[0046] Embodiment 2, as Figure 7-Figure 11As shown, a heating atomization core includes the liquid guide 2 in Example 1, a heating element 3 attached to the liquid guide 2, and the heating element 3 is connected to the electrode lead 4. When working, the electrode lead 4 supplies power to the heating element 3 to generate heat, so that the smoke liquid in the liquid guide 2 is atomized to form atomized steam, which is finally inhaled by the user.

[0047] like Figure 7-Figure 9 As shown, the heating element 3 includes a heating circuit in the middle with electrode leads 4 connected at both ends. It is generally made of alloys with high resistivity such as stainless steel, nickel-chromium, iron-chromium-aluminum, nickel-iron, etc. The heating element 3 can be divided into a cylindrical heating element 3 curled up from a flat mesh heating element 3, a heating element 3 made of spiral wire, and a heating element 3 formed by cutting and hollowing out a metal tube. The direction of its heating circuit can be roughly divided into three types, a heating element 3 that extends horizontally as a whole, a heating element 3 that extends vertically as a whole, or a heating element 3 with a mesh structure.

[0048] Example 2-1, as Figure 10-11 As shown, the heated atomizer core also includes an atomizer core shell 1, a liquid guide 2 is arranged in the atomizer core shell 1, a fixing member 5 for fixing the electrode is arranged in the atomizer core shell 1 below the liquid guide 2, and an air flow inlet hole 51 is opened in the fixing member 5. The heating element 3 is attached to the liquid guide 2, and the liquid guide 2 is arranged in the atomizer core shell. With the restraint of the atomizer core shell 1, the liquid guide 2 and the heating element 3 are fixed in the atomizer core shell 1. At the same time, the fixing part 5 fixes the electrode lead 4, thereby avoiding the problem that the heating circuit of the heating element 3 shakes together after the electrode lead 4 shakes under force, and solving the problem that the liquid guide 2 and the heating element 3 are in poor contact; the side wall of the atomizer core shell 1 is provided with a liquid guide hole 11, and the size of the liquid guide hole 11 controls the contact area between the liquid and the liquid guide 2. When working, the liquid enters the liquid guide 2 from the liquid guide hole 11 on the side wall of the atomizer core shell 1 and flows to the liquid guide 2. The electrode lead 4 supplies electricity and heat to the heating element 3, so that the smoke liquid in the liquid guide 2 is atomized to form atomized steam. At this time, the gas entering from the air flow inlet hole 51 brings the atomized steam into the air flow channel, which is finally inhaled by the user.

[0049] like Fig.11 As shown, a positioning groove 52 is provided on the outer periphery of the fixing member 5, and the electrode lead 4 is clamped in the positioning groove 52 and fixed. The shape of the cross section of the positioning groove 52 can be arc-shaped, U-shaped, V-shaped, square and the like, preferably V-shaped, with a large opening, easy to insert, and can completely clamp and fix the electrode lead 4. At least one positioning groove 52 is provided, and one is provided to fix the two electrode leads 4 together. When two positioning grooves 52 are provided, the two electrode leads 4 are clamped in different positioning grooves 52. A plurality of positioning grooves 52 are provided, and the plurality of positioning grooves 52 are evenly provided on the outer periphery of the fixing member 5, and the two electrode leads 4 are clamped in any two positioning grooves 52. Another embodiment is that the fixing member 5 is provided with a through fixing hole, and the electrode lead 4 is inserted into the fixing hole.

[0050] In Example 2-2, the heating circuit of the heating element 3 is correspondingly embedded in the concave texture of the liquid-conducting body 2 or between adjacent convex textures. The embedding in the text means that the heating circuit of the heating element 3 can be inserted as a whole into the concave texture of the liquid-conducting body 2 or between adjacent convex textures, or can be partially inserted into the concave texture of the liquid-conducting body 2 or between adjacent convex textures; when inserted as a whole, the heating circuit has the same texture as the liquid-conducting cloth 21. The area of ​​the heating element 3 embedded in the liquid-conducting body 2 is not the more the better. Too much area of ​​the heating element 3 embedded in the liquid-conducting body 2 will cause the heating element 3 to be completely soaked in the liquid of the liquid-conducting body 2. When atomization is working, the atomized vapor will be completely wrapped by the liquid, which may easily cause problems such as oil frying. Preferably, the area of ​​the heating element 3 embedded in the heat conductor accounts for 1 / 3-2 / 3 of the total area of ​​the heating circuit of the heating element 3. At this time, problems such as oil frying and burning are not likely to occur, and the heat of the heating element 3 can be utilized to the maximum extent in the atomization work, thereby improving the atomization effect, thereby improving the user's smoking experience.

[0051] In Example 2-3, the size of the heating wire diameter of the heating element 3, whether the extension direction of the heating circuit is consistent with the direction of the grain of the liquid guiding cloth 2, all have a certain influence on the atomization effect of the atomization core; the liquid guiding cloth 2 can form transverse grains and / or vertical grains after design and processing, that is, it has transverse microgrooves 22 and / or vertical microgrooves 22. When the liquid guiding cloth 2 and the heating element 3 are bonded, the direction of the grain is extremely important. When the transversely extending heating element 3 and the liquid guiding cloth 21 with vertical grains are bonded, the heating circuit of the heating element 3 is embedded in the liquid guiding cloth 2 with a smaller area; when the transversely extending heating element 3 and the liquid guiding cloth 2 with transverse grains are bonded, the heating circuit of the heating element 3 is embedded in the liquid guiding cotton with a larger area. When the wire diameter of the heating element 3 is relatively thick, for example, 0.2 mm or more, the extension direction of the heating circuit of the heating element 3 and the grain direction of the liquid-conducting body 2 are generally consistent with each other, such as the heating circuit of the heating element 3 extends horizontally, and the grain direction of the liquid-conducting body 2 is also horizontal, that is, the microgrooves 22 are horizontal microgrooves 22, so that the contact area between the heating element 3 and the liquid-conducting body 2 is larger, and the atomization area is increased. When the wire diameter of the heating element 3 is relatively thin, for example, the wire diameter is less than 0.15 mm, the extension direction of the heating circuit of the heating element 3 and the grain direction of the liquid-conducting body 2 are generally inconsistent with each other, such as the heating circuit of the heating element 3 extends horizontally, and the grain direction of the liquid-conducting body 2 is vertical, that is, the microgrooves 22 are vertical microgrooves 22, and the atomization effect of the atomization core will be better.
