The heating wires are made into a spring-like structure, and then the heating wires are embedded in the ceramics to heat the ceramics, thereby atomizing the aerosol matrix to produce aerosols. Since the porosity of the ceramics has the effect of intercepting or adsorbing the flavor substances in the aerosol matrix, after the aerosol matrix is ​​atomized into an aerosol, the taste of the aerosol varies greatly, especially the expression of the aerosol taste is incomplete, so there is a big difference between the taste of the aerosol and the original taste of the aerosol matrix.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0026] The present application provides an atomizer core 100, see Figure 1 to Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of the atomizer core provided by the present application. Figure 2 yes Figure 1 Schematic diagram of the explosion structure of the atomizer core shown.

[0027] The atomizer core 100 includes a fixed tube 10, a heating element 20 and a multi-layer liquid-conducting layer 30. The heating element 20 is arranged in the fixed tube 10; the multi-layer liquid-conducting layer 30 is arranged around the outer periphery of the heating element 20 and is located between the heating element 20 and the fixed tube 10. The multi-layer liquid-conducting layer 30 has at least two different heat-resistant temperatures, wherein the heat-resistant temperature of the liquid-conducting layer 30 in contact with the heating element 20 is 180°C-450°C, and the heat-resistant temperature of the liquid-conducting layer 30 in contact with the fixed tube 10 is lower than the heat-resistant temperature of the liquid-conducting layer 30 in contact with the heating element 20.

[0028] The heat-resistant temperature of the liquid-conducting layer 30 in contact with the heating element 20 may specifically be 180°C, 200°C, 220°C, 250°C, 280°C, 320°C, 340°C, 360°C, 400°C or 450°C.

[0029] The heat-resistant temperature of the liquid-conducting layer 30 in contact with the heating element 20 is relatively high. For example, the boiling point of the aerosol matrix atomized by the heating element 20 is 200°C. The heat-resistant temperature of the liquid-conducting layer 30 in contact with the heating element 20 can be 210°C or 230°C, which is higher than the boiling point, so that when the liquid-conducting layer 30 is infiltrated with liquid, it is prevented from being burned by the heating element 20. At the same time, the aerosol matrix can also be atomized, which can improve the taste of the generated aerosol. The heat-resistant temperature of the liquid layer 30 can be set lower, so that the liquid-conducting layer 30 far away from the heating element 20 can select a material with better liquid conductivity when the requirement for the heat-resistant temperature is relatively low, so as to improve the liquid-conducting efficiency of the multi-layer liquid-conducting layer 30 and reduce the risk of dry burning caused by low liquid-conducting efficiency; thus, these measures can effectively avoid the problem of aerosol taste odor caused by burnt taste caused by atomization, so that the atomization core provided in the present application can have a higher degree of restoration of the original taste expression of the aerosol matrix.

[0030] Preferably, the heat-resistant temperature of the liquid-conducting layer 30 in contact with the heating element 20 is 220°C-370°C, which is applicable to the boiling point temperature of most aerosol matrices during atomization, and can prevent the liquid-conducting layer 30 from being burned. It is also convenient to select a material with high cost-effectiveness and suitable liquid conductivity to make the liquid-conducting layer 30.

[0031] Furthermore, the multi-layer liquid-conducting layer 30 has at least two different textures, wherein the liquid-conducting layer 30 in contact with the heating element 20 has a vertical texture, and the extending direction of the vertical texture is parallel to the axial direction of the fixing tube 10 .

[0032] The multi-layer liquid-conducting layer 30 is formed with a vent hole 311 , which is coaxial with the fixed tube 10 . The heating element 20 is arranged on the wall of the vent hole 311 . The heating element 20 is used to atomize the aerosol matrix conducted through the multi-layer liquid-conducting layer 30 and generate aerosol in the vent hole 311 .

[0033] The fixing tube 10 is tubular and used to support the heating element 20 and the multi-layer liquid-conducting layer 30 ; the heating element 20 and the multi-layer liquid-conducting layer 30 both have a certain elasticity, and the elasticity of the heating element 20 allows the multi-layer liquid-conducting layer 30 to be fixed in the fixing tube 10 as well.

[0034] In the present application, a liquid inlet groove 12 is provided on the side wall of the fixed tube 10 , and the multi-layer liquid conducting layer 30 covers the liquid inlet groove 12 , and the aerosol matrix can enter the multi-layer liquid conducting layer 30 through the liquid inlet groove 12 , that is, the liquid inlet groove 12 is used for liquid inlet.

[0035] In some embodiments, the liquid-conducting layer 30 is cylindrical so that it can be completely accommodated in the fixing tube 10 .

[0036] In this 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-conducting layer 30 is clamped in the clamping groove 14, so that the end of the liquid-conducting layer 30 is also exposed outside the fixed tube 10, which can further increase the liquid inlet area of ​​the liquid-conducting layer 30, so that the liquid supply to the multi-layer liquid-conducting layer 30 is more sufficient.

[0037] Specifically, the liquid conducting layer 30 includes a surrounding portion 301 of an integral structure and guide portions 302 located at both ends of the surrounding portion 301, wherein the surrounding portion 301 is attached to the outer periphery of the heating element 20, and the guide portion 302 is relatively bent and connected to the surrounding portion 301 and extends outward, and the guide portions 302 located at both ends of the surrounding portion 301 are stacked and clamped in the clamping groove 14, so that the guide portion 302 can be used as a new liquid supply path, and the guide portion 302 is also connected to the clamping groove 14 as a connecting member, thereby further tightening the position of the multi-layer liquid conducting layer 30 and the heating element 20.

[0038] Furthermore, the guide portion 302 can also extend outside the fixed tube 10 to further increase the liquid supply area, and it can directly contact the liquid storage cotton in the liquid storage bin to improve the liquid supply efficiency.

[0039] In this embodiment, the length of the clamping groove 14 along 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-conducting layer 30 enters the clamping groove 14 from the opening 140 and is clamped in the clamping groove 14, that is, the guide portion 302 enters the clamping groove 14 from the opening 140 and is clamped in the clamping groove 14.

[0040] 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 portion 301 covering the liquid inlet groove 12 , it can be ensured that the liquid guiding layer 30 covers the liquid inlet groove 12 to prevent leakage of the aerosol matrix.

[0041] The heating element 20 is a heating net, which may include a first heating net 21 and a second heating net 22 arranged along the axial direction of the fixed tube 10. The first heating net 21 and the second heating net 22 are wound circumferentially to form a cylindrical structure. The first heating net 21 and the second heating net 22 both include a plurality of arranged heating units, which may be diamond units, rectangular units or triangular units, etc. The heating units and edge extensions on the heating nets are used to generate heat to atomize the aerosol matrix conducted from the multi-layer liquid-conducting layer 30.

[0042] In this embodiment, the shaped hole surrounded by the heating element 20 is basically a circular hole, which can improve the fluidity of the aerosol and prevent the aerosol from being retained in the airway of the circular hole and causing insufficient expression of the aerosol aroma; the heating element 20 is relatively located between the two ends of the liquid guiding layer 30 in the axial direction, and the distance formed between the end of the heating element 20 and the liquid guiding layer 30 in the axial direction is 2-50mm; preferably, the distance formed between the end of the heating element 20 and the liquid guiding layer 30 in the axial direction is 3-15mm.

[0043] The distance formed end to end between the heating element 20 and the liquid guiding layer 30 in the axial direction can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm or 50mm.

[0044] The shaping hole surrounded by the heating element 20 is basically a circular hole, and the end-to-end distance between the heating element 20 and the liquid-conducting layer 30 is further set to 2-50 mm, specifically 2 mm, 5 mm, 12 mm, 15 mm, 20 mm, 30 mm, 40 mm or 50 mm, which can avoid the excess portion of the liquid-conducting layer 30 from collapsing when it is full of aerosol matrix, thereby avoiding affecting the aerosol discharge and the taste of the aerosol.

[0045] Optionally, the shaped hole surrounded by the heating element 20 can also be a rectangular hole, and the present application does not make specific restrictions on this. The multi-layer liquid-conducting layer 30 is stacked, and the multi-layer liquid-conducting layer 30 includes at least two layers of liquid-conducting layers 30, each layer of liquid-conducting layer 30 can have a different texture, or there are two or three layers of liquid-conducting layers 30 with the same texture, and the present application does not make specific restrictions on this.

[0046] The liquid conducting layer 30 may be made of materials such as fiber, cotton or silk, and may have a variety of textures due to different manufacturing processes. The liquid conducting layers 30 with different textures have differences in liquid conductivity and transmittance. By sorting the liquid conducting layers 30 with different textures, the atomization performance of the atomization core 100 can be improved.

[0047] The texture gaps between the textures formed by the liquid guiding layer 30 are easier to guide liquid and pass the aroma substances in the aerosol matrix than the material of the liquid guiding layer 30 itself, and 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 30, so the vertical texture can play a guiding role, and the atomizer core 100 is usually used in a vertical posture. When in use, the axial direction of the fixed tube 30 is basically the same as the vertical direction, and the heating unit on the heating element 20 is closely attached to the surface of the liquid guiding layer 30. When in use, the vertical texture of the liquid guiding layer 20 helps to speed up the flow of the aerosol matrix to the heating unit of the heating element 20, reduce the aroma substances in the aerosol matrix being intercepted and retained in the liquid guiding layer 30, and improve the taste restoration of the aerosol generated by the atomizer core 100, so that the taste of the generated aerosol can be closer to the designed taste, and the original taste of the aerosol matrix is ​​more fully expressed.

[0048] Furthermore, the multi-layer liquid-conducting layer 30 is also provided with other textures different from the vertical grain textures, so as to adjust the liquid conduction rate of the aerosol matrix in the multi-layer liquid-conducting layer 30 by setting other textures, so as to avoid a greater risk of leakage of the atomizer core 100 due to too fast liquid supply. Therefore, the atomizer core 100 provided in the present application takes into account various indicators such as liquid supply rate, leakage risk and aerosol taste restoration through the texture setting of the multi-layer liquid-conducting layer 30, so that the atomizer core 100 provided in the present application has an appropriate liquid supply rate, a small leakage risk and a high aerosol taste restoration.

[0049] Specifically, the liquid conducting layer 30 in contact with the fixed tube 10 and the liquid conducting 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 conducting layer 30, so that the liquid supply rate of the multi-layer liquid conducting layer 30 is moderate, avoiding the problem of high risk of leakage caused by too fast liquid supply.

[0050] The liquid guide layer 30 in contact with the fixed tube 10 may have a grid texture or a horizontal stripe texture, and the extension direction of the vertical stripes is perpendicular to the extension direction of the horizontal stripes. Both the grid texture and the horizontal stripe texture can reduce the liquid inlet rate relative to the vertical stripe texture to avoid the risk of leakage caused by too fast liquid supply, and the passing rate of the flavor substance is also higher, which can make the flavor substance pass more easily, helping to improve the taste restoration of the aerosol.

[0051] For example, the liquid-conducting layer 30 in contact with the fixed tube 10 has a transverse texture, which is relatively perpendicular to the axial direction. The liquid-conducting layer 30 will relatively allow the aerosol matrix to supply liquid to the heating element 20 along the texture gap. The liquid-conducting layer 30 has a relatively blocking effect on the aerosol matrix flowing along the axial direction. Therefore, the liquid inlet rate of this liquid-conducting layer 30 will be reduced as a whole, thereby avoiding an increased risk of leakage due to too fast liquid supply.

[0052] 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 fluidity of the aerosol matrix in the liquid-conducting layer 30 with a grid texture and the penetration rate of the aroma substances are stronger, which can avoid the phenomenon of poor taste or insufficient aroma of the aerosol caused by the adsorption of too many aroma substances in the aerosol matrix.

[0053] In this embodiment, the multi-layer liquid-conducting layer 30 has at least vertical stripes, grid texture and horizontal stripes. The liquid-conducting layer 30 in contact with the fixed tube 10 has horizontal stripes, and the liquid-conducting layer 30 with the grid texture is located between the liquid-conducting layer 30 with the vertical stripes and the liquid-conducting layer 30 with the horizontal stripes.

[0054] 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.

[0055] Furthermore, the bulk density of the liquid-conducting layer 30 having a vertical 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 50-75 g / m 2 , preferably 55-65g / m 2 The bulk density of the liquid-conducting layer 30 having a horizontal texture is 40-85 g / m 2 , preferably 45-75g / m 2 .

[0056] The bulk density of the liquid-conducting layer 30 with vertical stripes may be 40 g / m 2 , 45g / m 2 , 50g / 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 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 .

[0057] Too large a volume density will result in insufficient penetration of the flavor substances in the aerosol matrix, affecting the taste restoration of the generated aerosol. Too small a volume density will result in excessive leakage rate of the atomizer core 100. Therefore, the present application further optimizes the liquid supply rate, leakage risk and taste restoration of the atomizer core 100 by limiting the volume density of the liquid guide layer 30 of each texture type.

[0058] Furthermore, the liquid conducting layer 30 with vertical stripes is made of natural fiber, which may be cotton or linen, etc. The liquid conducting layer 30 with grid texture is made of silk cotton, wood pulp cotton or organic cotton, and the liquid conducting layer 30 with horizontal stripes is made of non-woven fabric, silk, wood pulp cotton, polylactic acid (PLA) or polyethylene terephthalate (PET). These materials have high liquid conduction rate and high permeability to flavor substances in the aerosol matrix, which is beneficial to improving the aerosol taste restoration degree, and can also well guide the aerosol matrix to ensure sufficient liquid supply to the heating element 20.

[0059] The specific number of layers of the multi-layer liquid-conducting layer 30 can be 2 layers, 3 layers, 4 layers, 5 layers, 6 layers, 7 layers, 8 layers or 9 layers, etc., and this application does not make any specific limitation on this.

[0060] For example, the multi-layer liquid-conducting layer 30 includes five liquid-conducting layers 30, which are respectively named as the first layer 31, the second layer 32, the third layer 33, the fourth layer 34 and the fifth layer 35 from the direction close to the heat-generating element 20 to the direction away from the heat-generating element 20, wherein the first layer 31 and the second layer 32 are liquid-conducting layers 30 with vertical stripes, the third layer 33 and the fourth layer 34 are liquid-conducting layers 30 with grid textures, and the fifth layer 35 is a liquid-conducting layer 30 with horizontal stripes.

[0061] For example, the multi-layer liquid-conducting layer 30 includes six, seven or eight layers of liquid-conducting layers 30, wherein the first two layers close to the heating element 20 are liquid-conducting layers 30 with vertical stripes, the last two layers away from the heating element 20 are liquid-conducting layers 30 with horizontal stripes, and the remaining intermediate layers are liquid-conducting layers 30 with grid textures.

[0062] Table 1 is a statistical table showing the effect of the number of liquid-conducting layers 30 on the mouthfeel of the aerosol when the statistical variables are the number of layers of the liquid-conducting layer 30 and the diameter of the vent holes 311 and the total thickness of the liquid-conducting layer 30 are constant values.

[0063]

[0064] Table 1

[0065] From the analysis of Table 1, it can be seen that when the aperture of the vent hole 311 is 2.2 mm to 2.7 mm, the total thickness of the liquid conducting layer 30 is 0.2 mm to 1.5 mm, and the total number of layers of the liquid conducting layer 30 is in the range of 2 to 6 layers, the generated aerosol has the best taste indicators, can produce fragrance and sweetness, and has the highest taste restoration.

[0066] Table 2 below is a statistical table showing the effect of the texture distribution of the liquid-conducting layer 30 on the mouthfeel of the aerosol when the statistical variable is the texture distribution of the liquid-conducting layer 30 and the aperture of the vent 311 and the total thickness of the liquid-conducting layer 30 are constant values.

[0067]

[0068] Table 2

[0069] From the analysis in Table 2, it can be seen that when the aperture of the ventilation hole 311 is 2.2 mm to 2.7 mm, and the total thickness of the liquid conducting layer 30 is 0.2 mm to 1.5 mm, the texture distribution of the liquid conducting layer 30 is vertical stripes, grid stripes and horizontal stripes, and the generated aerosol has the best taste indicators, can produce fragrance and sweetness, and has the highest taste restoration.

[0070] Based on this, the present application also provides an assembly method of an atomizer core 100, wherein the atomizer core 100 is the atomizer core 100 as described above. Figure 3 , Figure 3 : is a schematic diagram of the flow of the atomizer core assembly method provided in the present application. The assembly method of the atomizer core 100 includes:

[0071] Step 10: Stack the multiple liquid-conducting layers in order and stack the heating element on the multiple liquid-conducting layers, wherein the multiple liquid-conducting layers and the heating element are both in a flat plate shape.

[0072] The liquid-conducting layers 30 with various texture types are stacked in order, and the heating element 20 is stacked on the multi-layer liquid-conducting layers 30, and the heating unit of the heating element 20 is located between the two ends of the liquid-conducting layers 30, so that the multi-layer liquid-conducting layers 30 and the heating element 20 are stacked in a flat plate shape.

[0073] Step 20: Place the shaping rod at the center of the heating element, and wind the multi-layer liquid-conducting layer and the heating element together on the shaping rod, and overlap the multi-layer liquid-conducting layer at both ends along the circumference of the shaping plate.

[0074] The shaping rod 101 can be a round rod. By winding the multi-layer liquid-conducting layer 30 and the heating element 20 together on the shaping rod 101, the shaping hole formed by the heating element 20 can be basically a round hole; further, the multi-layer liquid-conducting layer 30 is overlapped at both ends along the circumference of the shaping rod 101, so that the guide parts 302 are overlapped, so as to facilitate clamping in the clamping groove 14.

[0075] Step 30: Insert the shaping rod, the heating element wound on the shaping rod, and the multi-layer liquid-conducting layer into the fixing tube, wherein the end of the multi-layer liquid-conducting layer is clamped in the clamping groove of the fixing tube.

[0076] That is, after the guide portion 302 is clamped on the clamping groove 14 of the fixing tube 10 , the shaping rod 101 is pulled out to form the atomizer core 100 as described above, wherein the liquid guide layer 30 is also sealed into the liquid tank 12 . The atomizer core 100 can be conveniently assembled by this assembly method.

[0077] See also Figure 4 , Figure 4 It is a structural schematic diagram of an embodiment of the electronic atomization device provided in the present application.

[0078] Based on this, the present application also provides an atomizer 200, which includes the atomizer core 100 as described above. The liquid storage chamber in the atomizer 200 is used to store the aerosol matrix, and the atomizer core 100 is at least partially located in the liquid storage chamber, so that the aerosol matrix can enter the atomizer core 100 to supply liquid to the heating element 20. The atomizer 200 is a replaceable atomizer, and the atomizer 200 is detachably connected to the host 301 in the electronic atomization device, and the host 301 supplies power to the atomizer 200.

[0079] like Figure 4 As shown, the present application also provides an electronic atomization device 300, which includes the atomization core 100 as described above or the atomizer 200 as described above. The electronic atomization device 300 includes a host 301 and the atomizer 200 as described above, and the host 301 supplies power to the atomizer 200. The host 210 and the atomizer 100 can be detachably connected or an integrated structure.

[0080] The texture gaps between the textures formed by the liquid-conducting layer are easier to conduct liquid and pass the aroma substances in the aerosol matrix than the material of the liquid-conducting layer itself. The liquid-conducting layer in contact with the heating element is provided with a vertical texture, and the extension direction of the vertical texture is parallel to the axial direction of the fixed tube, so that the vertical texture can play a guiding role, and the atomizer core is usually used in a vertical posture. When in use, the axial direction of the fixed tube is basically the same as the vertical direction, and the heating unit on the heating element is closely attached to the surface of the liquid-conducting layer. When in use, the vertical texture of the liquid-conducting layer helps to speed up the flow of the aerosol matrix to the heating unit of the heating element, reduce the aroma substances in the aerosol matrix from being intercepted and retained in the liquid-conducting layer, and improve the atomization. The mouthfeel restoration of the aerosol generated by the core makes the mouthfeel of the generated aerosol closer to the designed mouthfeel and expresses the original taste of the aerosol matrix more fully; further, other textures different from the vertical grain texture are provided in the multi-layer liquid conducting layer to adjust the liquid conduction rate of the aerosol matrix in the multi-layer liquid conducting layer by setting other textures, so as to avoid a large risk of leakage of the atomizer core due to too fast liquid supply. Therefore, the atomizer core provided in the present application takes into account various indicators such as liquid supply rate, leakage risk and mouthfeel restoration of the aerosol through the texture setting of the multi-layer liquid conducting layer, so that the atomizer core provided in the present application has an appropriate liquid supply rate, a small risk of leakage and a high mouthfeel restoration of the aerosol.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
