DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] The terms "first", "second", "third", etc., in the embodiments of the present application are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implying the number of the technical features indicated. Thus, the features defined with "first", "second", "third" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed or can optionally include other steps or units inherent to the process, method, product or device.

[0029] Reference to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] The present application provides an atomizing core 100, referring to FIG. 1 to FIG. 2, FIG. 1 is a structural schematic diagram of an embodiment of the atomizing core provided by the present application, and FIG. 2 is an exploded structural schematic diagram of the atomizing core shown in FIG. 1.

[0031] The atomizing core 100 includes a fixed tube 10, a heating element 20 and a plurality of liquid guiding layers 30, the heating element 20 is arranged in the fixed tube 10; the plurality of liquid guiding layers 30 are annularly arranged on the outer periphery of the heating element 20 and located between the heating element 20 and the fixed tube 10, the plurality of liquid guiding layers 30 have at least two different heat-resistant temperatures, wherein the heat-resistant temperature of the liquid guiding layer 30 in contact with the heating element 20 is 180-450℃, and the heat-resistant temperature of the liquid guiding layer 30 in contact with the fixed tube 10 is lower than that of the liquid guiding layer 30 in contact with the heating element 20.

[0032] The heat-resistant temperature of the liquid guiding layer 30 in contact with the heating element 20 can be specifically 180℃, 200℃, 220℃, 250℃, 280℃, 320℃, 340℃, 360℃, 400℃ or 450℃.

[0033] The heat-resistant temperature of the liquid guiding layer 30 in contact with the heating element 20 is relatively high. For example, if the boiling point of the aerosol substrate atomized by the heating element 20 is 200 DEG C, the heat-resistant temperature of the liquid guiding layer 30 in contact with the heating element 20 can be selected as 210 DEG C or 230 DEG C, which is higher than the boiling point temperature. In this way, when the liquid guiding layer 30 is wetted by the liquid, the liquid guiding layer 30 can be prevented from being burnt by the heating element 20, and the aerosol substrate can be atomized at the same time, so that the taste of the generated aerosol can be improved. The heat-resistant temperature of the liquid guiding layer 30 far away from the heating element 20 can be relatively low. In this way, the liquid guiding layer 30 far away from the heating element 20 can be made of a material with better liquid guiding property, so that the liquid guiding efficiency of the multi-layer liquid guiding layer 30 can be improved, and the risk of dry burning caused by low liquid guiding efficiency can be reduced. In this way, the problems of aerosol taste caused by burnt taste due to atomization can be effectively avoided, and the reduction degree of the original taste of the aerosol substrate expressed by the atomizing core provided by the application can be higher.

[0034] Preferably, the heat-resistant temperature of the liquid guiding layer 30 in contact with the heating element 20 is 220 DEG C to 370 DEG C. This range can be suitable for the boiling point temperature of most aerosol substrates during atomization, and can also prevent the liquid guiding layer 30 from being burnt. In addition, the material with high performance and suitable liquid guiding rate can be selected to make the liquid guiding layer 30.

[0035] Further, the multi-layer liquid guiding layer 30 has at least two different textures. The liquid guiding layer 30 in contact with the heating element 20 has a vertical texture, and the extension direction of the vertical texture is parallel to the axial direction of the fixed tube 10.

[0036] The multi-layer liquid guiding layer 30 is formed with a ventilation hole 311 coaxial with the fixed tube 10. The heating element 20 is arranged on the wall surface of the ventilation hole 311, and the heating element 20 is used to atomize the aerosol substrate conducted by the multi-layer liquid guiding layer 30 and generate aerosol in the ventilation hole 311.

[0037] The fixed tube 10 is tubular and used to support the heating element 20 and the multi-layer liquid guiding layer 30. The heating element 20 and the multi-layer liquid guiding layer 30 both have elasticity. The elasticity of the heating element 20 can make the multi-layer liquid guiding layer 30 also fixed in the fixed tube 10.

[0038] In the application, the side wall of the fixed tube 10 is provided with a liquid inlet groove 12, and the multi-layer liquid guiding layer 30 covers the liquid inlet groove 12. The aerosol substrate can enter the multi-layer liquid guiding layer 30 through the liquid inlet groove 12, that is, the liquid inlet groove 12 is used for liquid inlet.

[0039] In some embodiments, the liquid guiding layer 30 is cylindrical, so that it can be completely accommodated in the fixed tube 10.

[0040] In the embodiment, the side wall of the fixed tube 10 is further provided with a clamping groove 14, and the end of the multi-layer liquid guide layer 30 is clamped in the clamping groove 14, so that the end of the liquid guide layer 30 is also exposed outside the fixed tube 10, the liquid inlet area of the liquid guide layer 30 can be further increased, and the liquid supply to the multi-layer liquid guide layer 30 is more sufficient.

[0041] Specifically, the liquid guide layer 30 includes an integral structure of a surrounding part 301 and guide parts 302 at both ends of the surrounding part 301, wherein the surrounding part 301 is attached to the outer periphery of the heating element 20, the guide parts 302 are bent and connected opposite to the surrounding part 301 and extend outward, and the guide parts 302 at both ends of the surrounding part 301 are stacked and clamped in the clamping groove 14, so that the guide parts 302 can serve as a new liquid supply path, and the guide parts 302 also serve as connecting parts connected with the clamping groove 14, thereby further fastening the positions of the multi-layer liquid guide layer 30 and the heating element 20.

[0042] Further, the guide parts 302 can also extend outside the fixed tube 10, further increasing the liquid supply area, which can directly contact the liquid storage cotton in the liquid storage compartment to improve the liquid supply efficiency.

[0043] In the embodiment, the length of the clamping groove 14 in the axial direction is greater than the length of the liquid inlet groove 12, and the clamping groove 14 is formed with an opening 140 at the end of the fixed tube 10, the end of the multi-layer liquid guide layer 30 enters the clamping groove 14 from the opening 140 and is clamped in the clamping groove 14, that is, the guide parts 302 enter the clamping groove 14 from the opening 140 and are clamped in the clamping groove 14.

[0044] By setting the length of the clamping groove 14 in the axial direction to be greater than the length of the liquid inlet groove 12, and the surrounding part 301 covering the liquid inlet groove 12, it can be ensured that the liquid guide layer 30 covers the liquid inlet groove 12, avoiding leakage of aerosol matrix.

[0045] The heating element 20 is a heating net, which can include a first heating net 21 and a second heating net 22 arranged in the axial direction of the fixed tube 10, the first heating net 21 and the second heating net 22 are wound in a circumferential direction to form a cylindrical structure, and the first heating net 21 and the second heating net 22 each include a plurality of heating units arranged in a row, which can be diamond-shaped units, rectangular units or triangular units, etc., and the heating units and edge extensions on the heating net are used for heating to atomize the aerosol matrix conducted from the multi-layer liquid guide layer 30.

[0046] In the embodiment, the shaping hole surrounded by the heating element 20 is a substantially circular hole, which can improve the flowability of the aerosol passing through and prevent the aerosol from being retained in the air passage of the circular hole to cause insufficient aroma expression of the aerosol; the heating element 20 is located between the two ends of the liquid guide layer 30 in the axial direction, and the distance between the heating element 20 and the liquid guide layer 30 in the axial direction is 2-50 mm; preferably, the distance between the heating element 20 and the liquid guide layer 30 in the axial direction is 3-15 mm.

[0047] The distance between the heating element 20 and the liquid guide layer 30 in the axial direction can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 10 mm, 12 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm or 50 mm.

[0048] The shaping hole surrounded by the heating element 20 is a substantially circular hole, and the distance between the heating element 20 and the liquid guide layer 30 is further set to 2-50 mm, which can be 2 mm, 5 mm, 12 mm, 15 mm, 20 mm, 30 mm, 40 mm or 50 mm, so as to avoid the collapse of the excess part of the liquid guide layer 30 when the aerosol substrate is filled, thereby avoiding affecting the aerosol discharge and the taste of the aerosol.

[0049] Alternatively, the shaping hole surrounded by the heating element 20 can also be a rectangular hole, which is not limited in the application.

[0050] The multi-layer liquid guide layer 30 is arranged in a stacked manner, and the multi-layer liquid guide layer 30 includes at least two layers of liquid guide layers 30. Each layer of liquid guide layer 30 can have different textures, or the textures of two or three layers of liquid guide layers 30 are the same, which is not limited in the application.

[0051] The liquid guide layer 30 can be made of fiber, cotton or silk, etc., which can form various textures due to different manufacturing processes. The liquid guide layers 30 with different textures have differences in liquid guiding rate and permeability, etc. The sorting of the liquid guide layers 30 with different textures can improve the atomization performance of the atomization core 100.

[0052] The texture gap between the textures formed by the liquid guide layer 30 is more conducive to the liquid guiding and the passage of flavoring substances in the aerosol substrate relative to the material of the liquid guide layer 30 itself, and the liquid guide layer 30 in contact with the heating element 20 has a vertical texture, the extension direction of the vertical texture is parallel to the axial direction of the fixed tube 30, so that the vertical texture can play a guiding role, and the atomization core 100 is usually used in a vertical posture, and the axial direction of the fixed tube 30 is basically the same as the vertical direction in use, and the heating unit on the heating element 20 is in close contact with the surface of the liquid guide layer 30, and the vertical texture of the liquid guide layer 20 helps to accelerate the flow of the aerosol substrate to the heating unit of the heating element 20 in use, reduces the interception and retention of flavoring substances in the aerosol substrate in the liquid guide layer 30, improves the taste reduction degree of the aerosol generated by the atomization core 100, so that the taste of the generated aerosol is closer to the designed taste, and the expression of the original taste of the aerosol substrate is more sufficient.

[0053] Further, the multi-layer liquid guide layer 30 is further provided with other textures different from the vertical texture, so as to adjust the liquid guiding rate of the aerosol substrate in the multi-layer liquid guide layer 30 through the arrangement of the other textures, so as to avoid the risk of large liquid leakage of the atomization core 100 due to too fast liquid supply. Therefore, the atomization core 100 provided in the present application considers the liquid supply rate, liquid leakage risk and taste reduction degree of the aerosol, so that the atomization core 100 provided in the present application has appropriate liquid supply rate, small liquid leakage risk and high taste reduction degree of the aerosol.

[0054] Specifically, the liquid guide layer 30 in contact with the fixed tube 10 and the liquid guide layer 30 in contact with the heating element 20 have different textures, which can relatively reduce the liquid inlet rate of the multi-layer liquid guide layer 30, so as to moderate the liquid supply rate of the multi-layer liquid guide layer 30 and avoid the problem of large liquid leakage risk caused by too fast liquid supply.

[0055] The liquid guide layer 30 in contact with the fixed tube 10 can have a grid texture or a cross texture, and the extension direction of the vertical texture is perpendicular to the extension direction of the cross texture. Both the grid texture and the cross texture can reduce the liquid inlet rate relative to the vertical texture, so as to avoid the problem of large liquid leakage risk caused by too fast liquid supply, and the passage rate of the flavoring substances is also high, which can make the flavoring substances more easily pass through, and help to improve the taste reduction degree of the aerosol.

[0056] For example, the liquid guide layer 30 in contact with the fixed tube 10 has a cross texture, and the cross texture is perpendicular to the axial direction. The liquid guide layer 30 will relatively allow the aerosol substrate to flow to the heating element 20 along the texture gap, and the liquid guide layer 30 has a relatively blocking effect on the aerosol substrate flowing in the axial direction, so that the liquid inlet rate of the liquid guide layer 30 as a whole will be reduced, thereby avoiding the problem of increased liquid leakage risk caused by too fast liquid supply.

[0057] The liquid-conducting layer 30 with a grid texture can also reduce the liquid inlet rate compared to the liquid-conducting layer 30 with a vertical stripe texture, and the aerosol matrix has stronger fluidity and penetration rate of flavor substances in the liquid-conducting layer 30 with a grid texture, which can avoid the phenomenon of poor taste or insufficient aroma of the aerosol caused by the adsorption of too many flavor substances in the aerosol matrix.

[0058] In this embodiment, the multi-layer liquid-conducting layer 30 has at least vertical stripes, a grid texture and a horizontal stripe texture. The liquid-conducting layer 30 in contact with the fixed tube 10 has a horizontal stripe texture, and the liquid-conducting layer 30 with a grid texture is located between the liquid-conducting layer 30 with a vertical stripe texture and the liquid-conducting layer 30 with a horizontal stripe texture.

[0059] By arranging different liquid-conducting layers 30 with vertical, grid, and horizontal textures in sequence, various indicators such as liquid supply rate, leakage risk, and aerosol taste restoration can be further taken into account, so that the atomizer core 100 provided in the present application has an appropriate liquid supply rate, a low leakage risk, and a high aerosol taste restoration.

[0060] Furthermore, the bulk density of the liquid-conducting layer 30 having vertical grain texture is 40-75 g / m 2 , preferably 55-70g / m 2 The bulk density of the liquid-conducting layer 30 having a grid texture is 50-75g / m 2 , preferably 55-65g / m 2 The bulk density of the liquid-conducting layer 30 having a horizontal texture is 40-85g / m 2 , preferably 45-75g / m2.

[0061] The bulk density of the liquid-conducting layer 30 with vertical grain texture may be 40 g / m 2 , 45g / m 2 / m 2 , 50g / m 2 , 55g / m 2 , 60g / m 2 , 65g / m 2 70gm 2 or 75g / m 2 The bulk density of the liquid-conducting layer 30 having a grid texture may be 50 g / m 2 , 55g / m 2 , 60g / m 2 , 65g / m 2 , 70g / m 2 or 75g / m 2 The bulk density of the liquid-conducting layer 30 having a horizontal texture may be 40 g / m 2 , 45g / m 2 , 50g / m 2, 55g / m 2 , 60g / m 2 , 65g / m 2 , 70g / m 2 , 75g / m 2 , 80g / m 2 , or 85g / m 2 .

[0062] Excessive bulk density will result in insufficient penetration of flavor substances in the aerosol substrate, affecting the taste reduction degree of the generated aerosol, and too small bulk density will result in excessive liquid leakage rate of the atomizing core 100. Therefore, by limiting the bulk density of the liquid guide layer 30 of each texture type, the liquid supply rate, liquid leakage risk, and taste reduction degree of the aerosol of the atomizing core 100 can be further optimized.

[0063] Further, the material of the liquid guide layer 30 with vertical texture is natural fiber, which can be cotton or flax, etc. The material of the liquid guide layer 30 with grid texture is silk cotton, wood pulp cotton or organic cotton. The material of the liquid guide layer 30 with horizontal texture is non-woven fabric, silk, wood pulp cotton, polylactic acid (PLA) or polyethylene terephthalate (PET). These materials have high liquid guide rate and high permeability to flavor substances in the aerosol substrate, which is beneficial to improve the taste reduction degree of the aerosol, and can also guide the aerosol substrate well to ensure sufficient liquid supply to the heating element 20.

[0064] The specific number of layers of the multi-layer liquid guide layer 30 can be 2, 3, 4, 5, 6, 7, 8 or 9, etc. The present application does not make specific limitation on this.

[0065] For example, the multi-layer liquid guide layer 30 includes five layers of liquid guide layer 30, which are respectively named as first layer 31, second layer 32, third layer 33, fourth layer 34 and fifth layer 35 from the direction close to the heating element 20 to the direction away from the heating element 20. The first layer 31 and the second layer 32 are liquid guide layers 30 with vertical texture, the third layer 33 and the fourth layer 34 are liquid guide layers 30 with grid texture, and the fifth layer 35 is a liquid guide layer 30 with horizontal texture.

[0066] For example, the multi-layer liquid guide layer 30 includes six, seven or eight layers of liquid guide layer 30, wherein the first two layers close to the heating element 20 are liquid guide layers 30 with vertical texture, the last two layers away from the heating element 20 are liquid guide layers 30 with horizontal texture, and the remaining middle layers are liquid guide layers 30 with grid texture.

[0067] Table 1 is a statistical data table of the taste of the aerosol with the number of layers of the liquid guide layer 30 as the statistical variable, and the pore diameter of the ventilation hole 311 and the total thickness of the liquid guide layer 30 as the constant value.

[0068] Table 1

[0069] From the analysis of Table 1, it can be known that when the pore diameter of the ventilation hole 311 is 2.2mm to 2.7mm, the total thickness of the liquid guide layer 30 is 0.2mm to 1.5mm, and the total layer number of the liquid guide layer 30 is in the range of 2 to 6, the generated aerosol has the best taste indicators, can emit fragrance and sweetness, and has the highest taste restoration degree.

[0070] Table 2 below is a statistical data table of the taste of the aerosol with the texture distribution of the liquid guide layer 30 as a statistical variable, and the pore diameter of the ventilation hole 311 and the total thickness of the liquid guide layer 30 as fixed values.

[0071] Table 2

[0072] From the analysis of Table 2, it can be known that when the pore diameter of the ventilation hole 311 is 2.2mm to 2.7mm, the total thickness of the liquid guide layer 30 is 0.2mm to 1.5mm, and the texture distribution of the liquid guide layer 30 is vertical lines, grid lines and horizontal lines, the generated aerosol has the best taste indicators, can emit fragrance and sweetness, and has the highest taste restoration degree.

[0073] Based on this, the application also provides an assembly method of the atomizing core 100, which is the atomizing core 100 as described above. Referring to FIG. 3, which is a flowchart of the assembly method of the atomizing core provided by the application, the assembly method of the atomizing core 100 comprises:

[0074] Step 10: stacking the multiple liquid guide layers in order and stacking the heating element on the multiple liquid guide layers, wherein the multiple liquid guide layers and the heating element are both in the form of a flat plate.

[0075] The liquid guide layers 30 with different texture types are stacked in order, and the heating element 20 is stacked on the multiple liquid guide layers 30. The heating unit of the heating element 20 is located between the two ends of the liquid guide layer 30, so that the multiple liquid guide layers 30 and the heating element 20 are stacked in the form of a flat plate.

[0076] Step 20: placing a shaping rod at the center position of the heating element, and winding the multiple liquid guide layers and the heating element on the shaping rod together, and stacking the multiple liquid guide layers at the two ends along the circumference of the shaping plate.

[0077] The shaping rod 101 can be a round rod. By winding the multiple liquid guide layers 30 and the heating element 20 on the shaping rod 101 together, the shaping hole formed by the heating element 20 can be basically a round hole. Further, the multiple liquid guide layers 30 are stacked at the two ends along the circumference of the shaping rod 101, that is, the guide portions 302 are stacked to be clamped in the clamping groove 14.

[0078] Step 30: the shaping rod, the heating element and the multi-layer liquid guide layer are inserted into the fixing tube, and the end of the multi-layer liquid guide layer is clamped in the clamping groove of the fixing tube.

[0079] That is, after the guide part 302 is clamped in the clamping groove 14 of the fixing tube 10, the shaping rod 101 is pulled out to form the atomization core 100 as described above, wherein the liquid guide layer 30 also covers the liquid inlet groove 12. Through the assembly method, the atomization core 100 can be conveniently assembled.

[0080] Referring to FIG. 4, FIG. 4 is a structural schematic diagram of an embodiment of an electronic atomization device provided by the present application.

[0081] Based on this, the present application further provides an atomizer 200, which comprises the atomization core 100 as described above. The liquid storage cavity in the atomizer 200 is used to store the aerosol substrate, and the atomization core 100 is at least partially located in the liquid storage cavity, so that the aerosol substrate can enter the atomization core 100 to supply liquid to the heating element 20. The atomizer 200 is a replaceable atomizer, and the atomizer 200 is detachably connected with the main machine 301 of the electronic atomization device, and the main machine 301 supplies power to the atomizer 200.

[0082] As shown in FIG. 4, the present application further provides an electronic atomization device 300, which comprises the atomization core 100 as described above or the atomizer 200 as described above. The electronic atomization device 300 comprises the main machine 301 and the atomizer 200 as described above, and the main machine 301 supplies power to the atomizer 200. The main machine 210 and the atomizer 100 can be detachably connected or in an integrated structure.

[0083] Different from the prior art, the application discloses an electronic atomization device, an atomizer, an atomizing core and an assembling method thereof. The texture gap between the textures formed by the liquid guide layer is more conducive to guiding the liquid and passing the flavoring substances in the aerosol substrate than the material of the liquid guide layer itself. By arranging the liquid guide layer in contact with the heating element to have vertical texture, the extension direction of the vertical texture is parallel to the axial direction of the fixed tube. Therefore, the vertical texture can play a guiding role. The atomizing core is usually used in a vertical posture. In use, the axial direction of the fixed tube is basically the same as the vertical direction. The heating unit on the heating element is in close contact with the surface of the liquid guide layer. In use, the vertical texture of the liquid guide layer helps to accelerate the flow of the aerosol substrate to the heating unit of the heating element, reduces the interception and retention of the flavoring substances in the aerosol substrate in the liquid guide layer, improves the taste reduction degree of the aerosol generated by the atomizing core, and makes the taste of the generated aerosol closer to the designed taste, and the expression of the original taste of the aerosol substrate is more sufficient. Further, the multi-layer liquid guide layer is further provided with other textures different from the vertical texture, so as to adjust the liquid guiding rate of the aerosol substrate in the multi-layer liquid guide layer by arranging the other textures, so as to avoid the risk of liquid leakage of the atomizing core caused by too fast liquid supply. Therefore, the atomizing core provided in the application considers the consideration of the liquid supply rate, the liquid leakage risk and the taste reduction degree of the aerosol, so that the atomizing core provided in the application has appropriate liquid supply rate, small liquid leakage risk and high taste reduction degree of the aerosol.

[0084] Further, by limiting the heat-resistant temperature of the liquid guide layer in contact with the heating element to be relatively high, the liquid guide layer can be prevented from being burned by the heating element when it is soaked with liquid, and the aerosol substrate can be atomized at the same time, so as to improve the taste of the generated aerosol. The heat-resistant temperature of the liquid guide layer away from the heating element can be set to be relatively low, so that the liquid guide layer away from the heating element can be selected to have better liquid guiding property under the condition that the requirement for the heat-resistant temperature is relatively low, so as to improve the liquid guiding efficiency of the multi-layer liquid guide layer and reduce the risk of dry burning caused by low liquid guiding efficiency. Therefore, by the above measures, the problem of abnormal taste of the aerosol caused by the burnt taste of the atomization can be effectively avoided, and the reduction degree of the expression of the original taste of the aerosol substrate by the atomizing core is higher.

[0085] The above is only an embodiment of the application, and does not limit the patent scope of the application. Any equivalent structure or equivalent process transformation based on the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the application.
