[0038] 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.

[0039] 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.

[0040] 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.

[0041] Embodiment 1, as Figure 1-Figure 7As shown, a heated atomizer core includes an atomizer core shell 30, a cylindrical liquid guide 33 is arranged in the atomizer core shell 30, a heating element 31 is attached to the inner wall of the liquid guide 33, and the heating element 31 is connected to the electrode 32; a liquid guide hole 301 for guiding the liquid 33 is arranged on the side wall of the atomizer core shell 30, and one or more liquid guide holes 301 are arranged, and the number is not specifically limited; the liquid guide 33 is a cylindrical structure formed by overlapping and rolling multiple layers of liquid guide cloth, and the liquid guide cloth includes at least one layer of vertical-striped liquid guide cloth 332 and / or at least one layer of horizontal-striped liquid guide cloth 331, and the overlapping position of the horizontal-striped liquid guide cloth 331 and the vertical-striped liquid guide cloth 332 is not limited, and can be arranged on the inner side to fit the heating element 31, or in the middle, and of course can also be arranged The liquid-guiding cloth 331 is arranged on the outside and in contact with the liquid-guiding hole 301; each layer of the liquid-guiding cloth can be a horizontal liquid-guiding cloth 331, or each layer can be a vertical liquid-guiding cloth 332, and of course, both horizontal liquid-guiding cloth 331 and vertical liquid-guiding cloth 332 can be provided. Preferably, the vertical liquid-guiding cloth 331 is arranged on the innermost side and fits the heating element 31, and the horizontal liquid-guiding cloth 331 is arranged on the outermost side and in contact with the liquid-guiding hole 301; the vertical liquid-guiding cloth 332 is provided with microgrooves and / or microridges formed by the overall vertical arrangement of the lines; the horizontal liquid-guiding cloth 331 is provided with microgrooves and / or microridges formed by the overall horizontal arrangement of the lines; a fixing part 34 for fixing the electrode 32 is provided in the atomization core shell 30 below the liquid-guiding body 33, and the fixing part 34 is provided with an air flow inlet hole 341. During operation, liquid enters the liquid guiding liquid 33 from the liquid guiding hole 301 on the side wall of the atomizer core shell 30, flows to the transverse liquid guiding cloth 331 on the outside of the liquid guiding liquid 33, and the liquid flows circumferentially along the transverse micro-ridges and micro-grooves and penetrates into the vertical liquid guiding cloth 332 of the inner layer. The heating element 31 is embedded in the micro-grooves and between the micro-ridges on the vertical liquid guiding cloth 332. The electrode 32 supplies power to the heating element 31 for heating, so that the smoke liquid in the liquid guiding liquid 33 is atomized to form atomized steam. At this time, the gas entering from the air flow inlet hole 341 brings the atomized steam into the air flow channel, which is finally inhaled by the user.

[0042] like Figure 15-18 As shown, the vertical liquid-guiding cloth 332 is generally arranged vertically. The overall vertical arrangement means that the overall lines of the liquid-guiding cloth extend from the upper end to the lower end, but it is not required that each line is set from top to bottom. It can also be a branch line extending outward on the basis of the vertical lines, or the vertical lines and horizontal lines can be staggered. The vertical liquid-guiding cloth 332 has lines arranged generally vertically, which can make the formed micro grooves and micro ridges become vertical installation channels. The vertical heating circuit of the heating element 31 can be slightly embedded in this channel, thereby increasing the contact area between the heating element 31 and the liquid-guiding body 33. Figure 8-Figure 14As shown, the overall horizontal arrangement of the liquid-guiding cloth 331 is horizontal. The overall horizontal arrangement means that the overall texture of the liquid-guiding cloth extends from the left to the right, but it is not required that each texture is arranged from left to right. It can also be a branch texture extending outward on the basis of the horizontal texture, or the vertical texture and the horizontal texture can be staggered. The overall horizontal arrangement of the texture of the liquid-guiding cloth 331 can form microgrooves and microridges. The microgrooves and microridges form capillary gaps, which become horizontal liquid-guiding channels. The conduction rate of the liquid along the horizontal microridges and microgrooves is higher than that in other directions, which can better guide the liquid to the surroundings, so that the liquid-guiding liquid 33 conducts liquid evenly, improves the liquid conduction efficiency and atomization effect, and enhances the user's smoking experience.

[0043] The heating element 31 can be a heating sheet made of metal, which is wound into a column to fit the inner wall of the heat conductor. It is generally made of stainless steel, nickel-chromium, iron-chromium-aluminum, nickel-iron and other alloys with high resistivity. The thickness can be between 0.03-0.2mm, and the specific thickness is not limited. The heating circuit and the electrode 32 can be formed by cutting or corrosion technology, and the welding electrode 32 lead is used to contact the external electrode 32. The end of the electrode 32 lead that extends out is preferably with an insulating skin, and the material of the lead can be pure nickel or copper wire with silver plating. In addition, a fixing part 34 is also provided, and the fixing part 34 can fix the electrode 32 lead to prevent the extended lead from being subjected to force, causing the internal heating element 31 to move, resulting in poor contact with the conductive liquid 33.

[0044] The vertical liquid-guiding cloth 332 is provided with 1-6 layers, and the specific number of layers is not limited. The overlapping manner of the multiple layers of the vertical liquid-guiding cloth 332 is as follows: the arrangement position of the lines of each layer of the vertical liquid-guiding cloth 332 corresponds at least partially in the radial direction. The correspondence here means that the vertical lines between the layers of the vertical liquid-guiding cloth 332 correspond one to one in shape and position, and are the same or substantially the same in size, so that the heating circuit of the heating element 31 is at least partially embedded in the micro-grooves of the lines or between adjacent micro-ridges. The correspondence here can be partial correspondence, and of course it can also be full correspondence; in this way, the contact area between the heating element 31 and the vertical liquid-guiding cloth 332 can be increased, that is, the atomization area of ​​the atomization surface is increased, so that the smoke liquid in the liquid-guiding body 33 can be atomized to a greater extent, thereby improving the atomization effect.

[0045] In some embodiments, the vertical liquid-guiding fabric 332 and the horizontal liquid-guiding fabric 331 may be arranged in various ways, such as Figure 8-Figure 19 As shown, the lines provided on the vertical liquid-conducting cloth 332 and the horizontal liquid-conducting cloth 331 are straight lines, curved lines, or a combination of at least one of them. Fig.10 , Fig.17 The single straight lines shown are arranged in a regular array, or they can be Fig.12 The irregular bifurcated pattern composed of straight lines shown in the figure can be as follows Fig. 9, Fig.16 The straight lines shown above form a broken line. The lines of the lines are not necessarily straight lines. They can be Fig.11 The wave shape formed by the curves shown, or Fig.13 The combination of straight lines and curves shown in the figure does not necessarily have to be a continuous linear distribution, but can also be as follows Figure 8 , Fig.18 As shown in the long strip distribution; or as Fig.14 The criss-cross curve type shown can of course also be a criss-cross straight line type; the direction of the broken line and curved line patterns has more liquid storage space than the straight line patterns, which can ensure sufficient oil supply during continuous working suction; when in use, the direction of the patterns only needs to meet the design principles, and the shape and arrangement of the patterns are not specifically limited. The design principle is: the patterns of the liquid-guiding cloth in contact with the heating element 31 are generally vertical, and the patterns of the liquid-guiding cloth in contact with the liquid-guiding hole 301 on the outside are generally horizontal.

[0046] There are multiple implementations for the arrangement of the lines of the vertical liquid-conducting cloth 332 and the horizontal liquid-conducting cloth 331. The lines on the vertical liquid-conducting cloth 332 are at least partially through from the top to the bottom, and the lines on the horizontal liquid-conducting cloth 331 are at least partially through from one end to the other end. The vertical lines of the vertical liquid-conducting cloth 332 are arranged to form micro-ridges or micro-grooves on the liquid-conducting cloth that fit the vertical heating circuit of the heating element 31. In order to increase the contact area between the two, at least a part of the lines of the liquid-conducting cloth are through from the top to the bottom, and the rest of the lines can be horizontal or oblique; of course, all the lines can also be through from the top to the bottom.

[0047] In some embodiments, the patterns on the vertical liquid-guiding cloth 332 are at least partially consistent with the shape of the heating element 31 , that is, the heating circuit of the heating element 31 is at least partially embedded in the micro-grooves of the patterns or between adjacent micro-ridges, thereby increasing the atomization area of ​​the heating element 31 and the vertical liquid-guiding cloth 332 .

[0048] In some embodiments, the transverse liquid-conducting cloth 331 is provided with 1-6 layers, and the multi-layer transverse liquid-conducting cloth 331 is overlapped in the following manners: the arrangement positions of the lines of each layer of the transverse liquid-conducting cloth 331 correspond at least partially in the radial direction, and the correspondence here means that the transverse lines of each layer of the liquid-conducting cloth correspond one to one in shape and position, and are the same or substantially the same in size, and the correspondence here may be partial correspondence, or of course, may be full correspondence; or the arrangement positions of the lines of adjacent layers of the transverse liquid-conducting cloth 331 are at least partially staggered in the radial direction, and the staggered arrangement here means that the microgrooves or microribs formed by the transverse lines of adjacent transverse liquid-conducting cloths 331 are staggered in position, that is, the protrusions of the microribs or microgrooves of the transverse lines of the transverse liquid-conducting cloth 331 are stuck in the grooves of the microribs or microgrooves of the transverse lines of the adjacent layer of the liquid-conducting cloth, so that the liquid conduction rate is accelerated, and the staggering here may be partial staggering, or of course, may be full staggering.

[0049] In some embodiments, the horizontal lines of the horizontal liquid-guiding cloth 331 and the vertical lines of the vertical liquid-guiding cloth 332 can be understood as micro-ridges or micro-grooves on the surface of the liquid-guiding cloth, and the concave-convex width of a single layer of liquid-guiding cloth is less than 0.5 mm and the depth is less than 0.1 mm. By controlling the height and spacing of the micro-ridges or micro-grooves to control the size of the liquid storage volume, the liquid-guiding liquid 33 will be saturated when the liquid adsorbed to a certain extent, avoiding the problem of oversaturation of the liquid-guiding liquid 33 and solving the problem of liquid overflowing from the liquid-guiding liquid 33 and ultimately affecting the atomization effect.

[0050] In some embodiments, the lines of the horizontally striped liquid-guiding cloth 331 radiate to both sides with the liquid-guiding hole 301 as the center. Such a configuration allows the liquid entering the liquid-guiding hole 301 to be quickly guided around both sides after entering the liquid-guiding cloth; or the density of the lines of the horizontally striped liquid-guiding cloth 331 near the liquid-guiding hole 301 is greater than the density at other positions. Such a configuration allows the liquid entering the liquid-guiding hole 301 to be guided around with the liquid-guiding hole 301 as the center point; or the lines of the horizontally striped liquid-guiding cloth 331 are evenly arranged horizontally.

[0051] The atomizer core housing 30 is a straight-cylindrical structure. Since the shape of the liquid-conducting liquid 33 is cylindrical, the atomizer core housing 30 is designed as a straight-cylindrical housing to match the liquid-conducting liquid 33. This can better fix the liquid-conducting liquid 33. The liquid-conducting liquid 33 formed by curling multiple layers of liquid-conducting cloth can be fixed inside the mounting housing. In some specific embodiments, in order to save costs, a metal tube is cut and formed. The metal tube has a tubular structure and a liquid-conducting hole 301 is provided on the side for liquid to enter.

[0052] In some embodiments, the atomizer core housing 30 can be formed by slotting the side of a tubular metal to facilitate the installation of the liquid guide 33 and the heating element 31. Preferably, a vertical groove 302 is provided on the side wall of the atomizer core housing 30. Figure 2As shown, the open end of the heating element 31 faces the horizontal interfaces of the rolled multi-layer liquid-conducting cloth, and the horizontal interfaces of the multi-layer liquid-conducting cloth are just inserted into the vertical groove 302 for fixing, so that the heating circuit in the heating element 31 can better fit the liquid-conducting liquid 33, improve the atomization effect, and avoid the problem that the horizontal interfaces of the multi-layer liquid-conducting cloth cannot fit well with the heating element 31. Of course, the side wall of the atomizer core shell 30 may not have grooves, such as Figure 1 , Figure 7 As shown, the rolled multi-layer liquid-conducting cloth is fixed in the inner cavity of the atomizer.

[0053] In some embodiments, Figure 3 , Figure 6 As shown, at least two vertical grooves 302 are provided on the side wall of the atomizer core housing 30, and both ends of the rolled multi-layer liquid-conducting cloth are fixed in one of the vertical grooves 302; or as shown in FIG. Figure 4 As shown, the multi-layer liquid-conducting cloth is provided with multiple sections, and the ends of two adjacent sections of the multi-layer liquid-conducting cloth are both inserted into a vertical groove 302 and fixed.

[0054] In some embodiments, the atomizer core shell 30 is a straight cylinder, and the two transverse ends of the multi-layer liquid-conducting cloth are connected one by one to form a plurality of overlapping cylindrical structures; or the two transverse ends of the multi-layer liquid-conducting cloth are integrally abutted to form an integral cylindrical structure; that is, the cylindrical liquid-conducting liquid 33 is fixed in the inner cavity of the straight-cylindrical atomizer core shell 30.

[0055] In some embodiments, the vertical liquid-guiding cloth 332 is woven from flax cotton fibers; the horizontal liquid-guiding cloth 331 is woven from spunlace non-woven fibers. The use of flax cotton fibers can withstand high temperatures, and the part in contact with the heating element 31 is not easily carbonized, and the service life will be longer. The vertical pattern is set to match the heating circuit structure of the heating element 31. The vertical direction can make the heating element 31 slightly embedded in the vertical liquid-guiding cloth 332 to increase the contact area. The use of non-woven fabric is due to the good liquid-guiding performance of non-woven fabrics. Setting it on the outside of the liquid-guiding liquid 33 can make the smoke oil more quickly guided to the heating element 31 on the inside. The use of horizontal patterns is that the horizontal patterns have horizontal microgrooves or microribs, so that a larger capillary gap is formed at the microgrooves or microribs of the horizontal liquid-guiding cloth 331. The conduction rate of the liquid along the microgrooves is higher than that in other directions. The liquid in the liquid inlet hole can be better guided to the circumferential direction, so that the columnar liquid-guiding liquid 33 is evenly fed.

[0056] In some implementations, the lower portion of the electrode 32 is bent and attached to the inner wall of the atomizer core housing 30 , the shape of the fixing member 34 matches the atomizer core housing 30 , and the electrode 32 is squeezed and fixed by the fixing member 34 ; or the fixing member 34 is an elastic member, and the electrode 32 is squeezed and fixed to the atomizer core housing 30 by the fixing member 34 .

[0057] In some embodiments, the outer wall of the fixing member 34 is provided with a groove, and the electrode 32 can be just snapped into the groove, and the fixing member 34 is fixed in the atomizer core housing 30; or the fixing member 34 is provided with a through fixing hole, and the electrode 32 is installed in the fixing hole and fixed.

Other structures in the heating atomization mechanism can adopt the existing technology, which will not be described in detail here.
