Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device, an atomization component for the electronic atomization device, and a liquid guiding element. Background Technology

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material may be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are aerosol-providing articles, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). Known electronic atomizing devices have a reservoir capable of holding 2 mL of liquid matrix, and an atomizing assembly consisting of a cylindrical capillary element surrounding a heating element to draw in the liquid matrix and atomize it to generate an aerosol. The capillary element is formed by multiple layers, such as 3-4 layers of fiber cotton, wound around the cylindrical heating element, serving to transfer the liquid matrix from the reservoir to the heating element while also preventing leakage of the liquid matrix through the capillary element via capillary adsorption. When the volume of the reservoir is further increased to a larger value, such as 10 mL, the capillary adsorption of the capillary liquid guiding element cannot prevent the liquid matrix in the reservoir from leaking out through the capillary liquid guiding element.

Additionally, the inner surface of the main housing 10 has retaining ribs 115 located within the reservoir 12.

[0120] In this embodiment, the complete airflow channel is defined by multiple components. Specifically, according to... Figures 2 to 6 As shown, the airflow path includes: external air entering from the air inlet 23 passes through the air hole 61 of the second base 60 and the annular lead wire isolation element 50 before entering the tubular element 11, and then passes through the atomizing assembly and / or heating element 40 and carries aerosol from the tubular element 11 and air pipe 114 to the air outlet 113 where it is inhaled.

[0121] In this embodiment, the complete airflow channel indicated by arrow R2 is defined by the second base 60, lead wire isolation element 50, heating element 40, tubular element 11, and air pipe 114, forming a flow path for air to exit from the air inlet 23 through the heating element 40 to the air outlet 113. Furthermore, after assembly, the resistance heating portion of the heating element 40 is exposed to the airflow channel to release aerosol into it.

[0122] See Figures 2 to 6 As shown, the atomizer 100 also includes:

[0123] A porous absorber element 70 is disposed between the end cap 20 and the second base 60. The porous absorber element 70 is made of a porous fiber or similar material. The porous absorber element 70 is arranged around the airflow channel and / or the air inlet 23 to absorb aerosol condensate or liquid matrix seeping from the airflow channel to the air inlet 23. The porous absorber element 70 has a clearance hole 71; after assembly, the clearance hole 71 provides an air connection between the air hole 61 of the second base 60 and the air inlet 23.

[0124] according to Figures 3 to 8 As shown, the atomizer 100 also includes:

[0125] A ventilation channel is connected between the air inlet 23 and the liquid storage chamber 12 to regulate the pressure inside the liquid storage chamber 12.

[0126] according to Figures 3 to 8 As shown, and Figure 6 As shown by arrows R31 and R32, the ventilation channel includes:

[0127] An air recess 25 is formed on the second side surface of the end cap 20; after assembly, the air recess 25 is connected to the air inlet 23 and / or airflow channel through a porous absorption element 70.

[0128] Specifically, the end cap 20 has a pin 24 for insertion into the second base 60; an air groove 25 extends to the pin 24. The second base 60 also defines a pin hole 67 through which the pin 24 of the end cap 20 passes. The pin hole 67 extends to the surface of the second base 60 facing the first base 80.

[0129] according to Figures 3 to 8 As shown, and Figure 6 As shown by arrows R31 and R32, the ventilation channel also includes:

[0130] A ventilation slot or slit 112 is disposed on the tubular element 11. In this embodiment, the ventilation slot or slit 112 is connected to a liquid perforation 111; specifically, the ventilation slot or slit 112 extends from the liquid perforation 111 away from the proximal end 110. The ventilation slot or slit 112 does not extend to the end of the tubular element 11.

[0131] In one embodiment, the ventilation slot or slit 112 spans the central hole 81 of the first base 80 and communicates with the air recess 25.

[0132] During use, according to Figure 6As shown by arrows R31 and R32, when the negative pressure in the liquid storage chamber 121 exceeds a predetermined threshold, air enters the liquid storage chamber 121 sequentially through the air groove 25 and the ventilation groove or slit 112, thereby relieving the negative pressure in the liquid storage chamber 121. When a supersaturated liquid matrix is ​​injected into the liquid storage chamber 12 during production or when the pressure inside the liquid storage chamber 12 is greater than the external pressure during use, the liquid matrix in the liquid storage chamber 12 will seep outward through the ventilation channel in the direction indicated by arrows R32 and R31 to balance the pressure difference between the liquid storage chamber 12 and the outside.

[0133] In this embodiment, the ventilation slot or slit 112 and the air recess 25 are staggered in the longitudinal direction of the atomizer 100. According to... Figure 8 As shown, an air communication groove 66 is arranged on the surface of the second base 60 facing the first base 80; the air communication groove 66 is arranged around the insertion groove 65. Figure 8 As shown, the longitudinally staggered ventilation slots or slits 112 and the air grooves 25 are connected by the air communication channel 66. The air communication channel 66 has a plurality of spaced protrusions 68; when a supersaturated liquid matrix is ​​injected into the liquid storage chamber 12 during production or when the pressure inside the liquid storage chamber 12 is greater than the external pressure during use, the protrusions 68 can block the liquid matrix that seeps outward into the air communication channel 66.

[0134] In some embodiments, a portion of the ventilation channel is formed or defined between the first base 60 and the end cap 20. For example, a portion of the ventilation channel defined by the air recess 25 is formed or defined between the first base 60 and the end cap 20.

[0135] In some embodiments, a portion of the ventilation passage is formed on the tubular element 11. For example, a portion of the ventilation passage defined by the ventilation slot or slit 112 is formed or defined on the tubular element 11.

[0136] In some embodiments, the ventilation passage spans across the first base 80 and / or the second base 60.

[0137] In some embodiments, the width and / or depth of the ventilation slot or slit 112 and / or air recess 25 are approximately between 0.2 and 2.0 mm.

[0138] In some embodiments, a portion of the ventilation groove or slit 112 of the ventilation channel flows over the first side surface of the liquid guiding element 30. The first side surface of the liquid guiding element 30 does not completely cover the ventilation groove or slit 112.

[0139] In this embodiment, the volume of the reservoir 12 is greater than 3 mL. For example, the volume of the reservoir 12 may be between 5 and 20 mL. In a specific embodiment, the volume of the reservoir 12 is 10 mL, which can store approximately 10 mL of liquid matrix.

[0140] In this embodiment, the liquid storage chamber 12 is not filled or arranged with capillary adsorption elements, so the liquid matrix is ​​not adsorbed and retained in the liquid storage chamber 12 by capillary adsorption elements.

[0141] In the embodiments, the viscosity of the liquid matrix at room temperature is between 70 mPa·s and 400 mPa·s.

[0142] In this embodiment, the tubular element 11 is made of stainless steel. Furthermore, the tubular element 11 made of stainless steel has a wall thickness of approximately 0.15 to 0.25 mm.

[0143] In one embodiment, the tubular element 11 has an inner diameter of 5.8–9 mm; in another embodiment, the tubular element 11 has an inner diameter of 6–8 mm. In a specific embodiment, the tubular element 11 has an outer diameter of 6.2–7.0 mm. In this embodiment, the tubular element 11 has an increased diameter compared to the stainless steel tube of the product with the 2 mL reservoir 12.

[0144] In some embodiments, the liquid guiding element 30 includes more liquid guiding layers and has a larger outer diameter. In one embodiment, the liquid guiding element 30 is wound from a capillary element comprising 7 to 15 liquid guiding layers; or, the liquid guiding element 30 comprises 7 to 15 liquid guiding layers. In some embodiments, the liquid guiding element 30 has an outer diameter of 6 to 9 mm.

[0145] In some embodiments, the ratio of the number of liquid-conducting layers in the liquid-conducting element 30 to the volume of the liquid storage chamber 12 is between 0.7 and 5:1, with units of layers / mL. More preferably, the ratio is between 0.8 and 3:1. More preferably, the ratio is between 0.8 and 1.5:1. In a more preferred embodiment, the ratio is between 0.9 and 1.2:1.

[0146] In some embodiments, the ratio of the inner diameter of the tubular element 11 to the number of liquid guiding layers in the liquid guiding element 30 is between 0.4 and 1.5:1, with the unit being mm / layer.

[0147] In a more preferred embodiment, the liquid guiding element 30 includes 9 to 12 liquid guiding layers.

[0148] For example in Figure 9 A schematic diagram of a liquid guiding element 30 according to one embodiment is shown. Figure 10 An exploded schematic diagram of the 12 liquid-conducting layers before the liquid-conducting element 30 is wound is shown; according to Figure 9 and Figure 10As shown, in this embodiment, the liquid guiding element 30 includes 12 liquid guiding layers.

[0149] In some embodiments, each liquid-conducting layer in the liquid-conducting element 30 has a thickness of approximately 0.2 to 0.5 mm. In some specific embodiments, each liquid-conducting layer in the liquid-conducting element 30 is prepared from a fibrous material through a textile process. For example, in some embodiments, the liquid-conducting layer is prepared from cotton fibers, flax fibers, silk fibers, non-woven fibers, wood pulp fibers, etc., through textile processing. Typically, in embodiments, the liquid-conducting layer has a thickness of 0.3 to 0.45 mm.

[0150] exist Figure 9 and Figure 10 In this embodiment, the liquid-conducting element 30 includes: liquid-conducting layers 311, 312, 313, 314, 315, 316, 317, 318, 319, 320, 321, and a heating layer 322 arranged sequentially from the outside to the inside. In this embodiment, the multiple liquid-conducting layers of the liquid-conducting element 30 are sequentially stacked or laminated together. Furthermore, the multiple liquid-conducting layers of the liquid-conducting element 30 are arranged continuously, rather than separated or spaced apart; or any two adjacent liquid-conducting layers of the liquid-conducting element 30 are in contact and bonded together, without any stainless steel tube, ceramic tube, or the like separating or partitioning them.

[0151] In the embodiments, for example Figures 11 to 12 As shown, the cylindrical liquid-conducting element 30 is prepared by winding multiple liquid-conducting layers. Figure 11 As shown, before winding, the two ends of multiple liquid-conducting layers are connected or stacked and anchored together by bonding or mechanical pressing to form a first fixed region 3100 and a second fixed region 3200 at both ends, which are used to provide retention and positioning for equipment or fixtures when the multiple liquid-conducting layers are wound into a cylindrical shape. Figure 11 As shown, because the first fixed region 3100 and the second fixed region 3200 mechanically press or bond multiple liquid guiding layers, the thickness of the first fixed region 3100 and the second fixed region 3200 is greater than the thickness of other unpressed or unbonded regions; the other unpressed or unbonded regions are relatively loose. According to... Figure 12 As shown, after multiple liquid-conducting layers are wound into a cylindrical shape, the first fixing region 3100 and the second fixing region 3200 extend radially outward and are located outside the main body of the cylindrical shape; the first fixing region 3100 and the second fixing region 3200 can be trimmed and removed as excess parts. In the preparation process, as... Figure 11As shown, by using scissors or a cutter along the cutting line S1, the excess portion extending radially outward after winding, i.e., the first fixing region 3100 and the second fixing region 3200, is cut or removed, and the cylindrical main body portion is obtained as a cylindrical liquid guiding element 30. And according to... Figure 9 and Figure 12 As shown, in the prepared liquid-conducting element 30, the liquid-conducting element 30 has a longitudinally extending joint gap 3300 extending through the liquid-conducting element 30; specifically, the joint gap 3300 is formed by the incomplete adhesion between the first fixing region 3100 and the second fixing region 3200 during the winding process. The joint gap 3300 extends from the first side surface of the liquid-conducting element 30 to the second side surface; this joint gap 3300 can be used to provide expansion space after the liquid-conducting element 30 is impregnated with a liquid matrix. Specifically, the joint gap 3300 is formed by the incomplete adhesion between the first fixing region 3100 and the second fixing region 3200 during the winding process.

[0152] In some embodiments, the plurality of liquid-conducting layers of the liquid-conducting element 30 include at least:

[0153] At least one first rapid liquid-conducting layer, such as liquid-conducting layer 311, is configured to absorb the liquid matrix more rapidly on the outside of the liquid-conducting element 30. The absorption and transfer rate of the liquid matrix by the first rapid liquid-conducting layer, such as liquid-conducting layer 311, is greater than the absorption and transfer rate of the liquid matrix by the other liquid-conducting layers of the liquid-conducting element 30. In some embodiments, the first rapid liquid-conducting layer, such as liquid-conducting layer 311, is made of wood pulp fibers and / or silk fibers and / or nonwoven fibers capable of relatively rapid liquid conduction; or, the first rapid liquid-conducting layer, such as liquid-conducting layer 311, is a wood pulp fiber layer and / or a silk fiber layer and / or a nonwoven fiber layer. Alternatively, the first rapid liquid-conducting layer, such as liquid-conducting layer 311, is located near or defines a first side surface of the liquid-conducting element 30 for rapid absorption of the liquid matrix.

[0154] In some embodiments, the first rapid liquid-conducting layer, such as liquid-conducting layer 311, prepared by weaving wood pulp fibers and / or silk fibers and / or nonwoven fibers has a basis weight of 40 g / m³. 2 ~80g / m 2 .

[0155] "Gram weight" is a standard term in the textile chemical industry. For textile fabrics, gram weight refers to the weight of the fabric per square meter. The gram weight of a textile fabric limits its thickness. Generally, the higher the gram weight, the thicker the fabric. Typical textile fabric thicknesses range from approximately 0.08 mm to 1.2 mm. Specifically, 10 g / m²... 2 Up to 50g / m 2 The weight corresponds to a thickness of 0.08 mm to 0.3 mm, 50 g / m². 2 Up to 100g / m2 The weight corresponds to a thickness of 0.3 mm to 0.5 mm, and so on, up to 420 g / m². 2 The weight corresponds to a thickness of 1.2 mm.

[0156] In some embodiments, the liquid guiding element 30 includes at least:

[0157] At least one second rapid liquid-conducting layer, such as liquid-conducting layer 312, absorbs and transfers the liquid matrix as quickly as possible near the outer side; and at least one second rapid liquid-conducting layer, such as liquid-conducting layer 312, is located within the first rapid liquid-conducting layer, such as liquid-conducting layer 311; or, at least one second rapid liquid-conducting layer, such as liquid-conducting layer 312, is arranged immediately adjacent to the inner side of the first rapid liquid-conducting layer, such as liquid-conducting layer 311.

[0158] In this embodiment, the second rapid liquid-conducting layer, such as liquid-conducting layer 312, is prepared from the same fibrous material as the first rapid liquid-conducting layer, such as liquid-conducting layer 311, for example, wood pulp fiber or silk fiber, thereby enabling relatively rapid transfer of the liquid matrix. Accordingly, the basis weight of the second rapid liquid-conducting layer, such as liquid-conducting layer 312, is 40 g / m³. 2 ~80g / m 2 .

[0159] In some specific embodiments, the basis weight of the first rapid liquid-conducting layer, such as liquid-conducting layer 311, and the second rapid liquid-conducting layer, such as liquid-conducting layer 312, is 60 g / m³. 2 .

[0160] In some embodiments, the first rapid liquid-conducting layer, such as liquid-conducting layer 311, and the second rapid liquid-conducting layer, such as liquid-conducting layer 312, are configured as a mesh with openings, the presence of which is advantageous for increasing the liquid-conducting rate; for example, the openings are formed by needle punching during textile manufacturing. In embodiments, the pore size and / or number and / or open area of ​​the mesh on the first rapid liquid-conducting layer, such as liquid-conducting layer 311, is greater than the pore size and / or number and / or open area of ​​the mesh on the second rapid liquid-conducting layer, such as liquid-conducting layer 312; this is advantageous for decreasing the liquid-conducting rate sequentially from the outside to the inside. In use, the liquid-conducting rate of the first rapid liquid-conducting layer, such as liquid-conducting layer 311, is greater than the liquid-conducting rate of the second rapid liquid-conducting layer, such as liquid-conducting layer 312.

[0161] In some specific embodiments, the mesh size of the first rapid liquid guiding layer, such as liquid guiding layer 311, is approximately 1 to 2 mm; the mesh size of the second rapid liquid guiding layer, such as liquid guiding layer 312, is approximately 0.5 to 1.2 mm.

[0162] exist Figure 10 In the illustrated embodiment, a first indentation pattern is arranged on the first rapid liquid guiding layer, such as liquid guiding layer 311, or the second rapid liquid guiding layer, such as liquid guiding layer 312.

[0163] The "dented texture" described above refers to the visible dented texture formed at the increased spacing between fibers during the textile fabric preparation process, through hydroentangling or roller pressing. This results in a non-uniform fiber layer. The width of these dented textures is less than 1 mm, approximately between 0.1 and 0.5 mm. In the embodiment, in the wound liquid-guiding element 30, the first dented texture extends circumferentially along the first rapid liquid-guiding layer, such as liquid-guiding layer 311, or the second rapid liquid-guiding layer, such as liquid-guiding layer 312. After circumferential unfolding, the first dented texture extends along the length direction.

[0164] In some embodiments, the fluid guiding element 30 further includes at least:

[0165] Multiple third rapid liquid-conducting layers, such as liquid-conducting layers 313, 314, and 315, are provided. Second rapid liquid-conducting layers, such as liquid-conducting layers 313, 314, and 315, are located inside and adjacent to the first rapid liquid-conducting layer (e.g., liquid-conducting layer 311) and the second rapid liquid-conducting layer (e.g., liquid-conducting layer 312). The multiple third rapid liquid-conducting layers are used to transfer the liquid matrix absorbed by the first rapid liquid-conducting layer and the second rapid liquid-conducting layer inwards.

[0166] In some embodiments, the third rapid liquid-conducting layer is prepared from wood pulp fibers or silk fibers with good ability to transfer and absorb liquid matrix. Alternatively, the third rapid liquid-conducting layer, such as liquid-conducting layer 313, liquid-conducting layer 314, and liquid-conducting layer 315, is a wood pulp fiber layer or a silk fiber layer. In some embodiments, the basis weight of the third rapid liquid-conducting layer, such as liquid-conducting layer 313, liquid-conducting layer 314, and liquid-conducting layer 315, is 40–80 g / m³. 2 In some specific embodiments, the basis weight of the third rapid liquid-conducting layer, such as liquid-conducting layer 313, liquid-conducting layer 314, and liquid-conducting layer 315, is 60 g / m³. 2 .

[0167] In some embodiments, the third rapid liquid-conducting layers, such as liquid-conducting layers 313, 314, and 315, do not have mesh openings, and therefore the liquid-conducting rate of the third rapid liquid-conducting layer is lower than that of the first rapid liquid-conducting layer, such as liquid-conducting layer 311, or the second rapid liquid-conducting layer, such as liquid-conducting layer 312. In other embodiments, the third rapid liquid-conducting layers, such as liquid-conducting layers 313, 314, and 315, do not have indentations or grooves, and therefore the liquid-conducting rate of the third rapid liquid-conducting layer is lower than that of the first rapid liquid-conducting layer, such as liquid-conducting layer 311, or the second rapid liquid-conducting layer, such as liquid-conducting layer 312.

[0168] Alternatively, in some embodiments, the third rapid fluid-conducting layer is not necessary.

Furthermore, when the heated layer 322 is wetted with a liquid matrix, it can withstand a temperature of at least 350°C, which is advantageous for enabling the product to meet the requirements of the national standard "Electronic Cigarettes" (GB 41700-2022).

[0171] In some embodiments, the heat-receiving layer 322 is woven from heat-resistant flax fibers, Australian cotton fibers, or nylon fibers. Alternatively, the heat-receiving layer 322 is a flax fiber layer. In some embodiments, the heat-receiving layer 322 has a density of 70 g / m³. 2 Up to 90g / m 2 The basis weight; in some specific embodiments, the basis weight of the heat-receiving layer 322 is 75 g / m³. 2 .

[0172] In some embodiments, a second indentation pattern is arranged on the heated layer 322. In this embodiment, the second indentation pattern forms an angle with the first indentation pattern, and thus they are not parallel. More preferably, the second indentation pattern is arranged perpendicular to the first indentation pattern. Specifically, the second indentation pattern extends along the axial direction of the liquid guiding element 30, and when unfolded, the second indentation pattern on the heated layer 322 extends along the length direction.

[0173] In some embodiments, the fluid guiding element 30 further includes at least:

[0174] A liquid-retaining conductive layer 321 is located outside and adjacent to the heated layer 322. The liquid-retaining conductive layer 321 has mesh-like openings, thus giving it a mesh-like structure. In embodiments, the mesh-like openings in the conductive layer 321 are used to buffer or store the liquid matrix; or the conductive layer 321 is configured as a liquid storage layer or a liquid matrix buffer layer. When the heating element 40, integrated with the heated layer 322, starts heating and atomizing the liquid matrix, the conductive layer 321 can quickly replenish the buffered or stored liquid matrix to the heated layer 322, preventing excessive instantaneous consumption of the liquid matrix on the heated layer 322, which could lead to dry burning or gelatinization.

[0175] In some embodiments, the capacity or amount of liquid matrix absorbed, buffered, or stored by the liquid-conducting layer 321 is greater than the capacity or amount of liquid matrix absorbed, buffered, or stored by the heating layer 322. In some embodiments, the pore size of the mesh in the liquid-conducting layer 321 is approximately between 0.5 mm and 2.5 mm.

[0176] In some embodiments, the liquid-conducting layer 321 is prepared from wood pulp fibers or silk fibers with good ability to transfer and absorb liquid matrix. Alternatively, the liquid-conducting layer 321 is a wood pulp fiber layer or a silk fiber layer. In some embodiments, the basis weight of the liquid-conducting layer 321 is 40 g / m³. 2 ~80g / m 2 In some specific embodiments, the basis weight of the liquid guiding layer 321 is 60 g / m³. 2 .

[0177] In some embodiments, the liquid-conducting layer 321 has a third indentation pattern formed or has a third indentation pattern; the third indentation pattern forms an angle with the second indentation pattern on the heated layer 322, and thus they are not parallel. More preferably, the third indentation pattern is arranged perpendicular to the second indentation pattern. Specifically, when wound, the third indentation pattern of the liquid-conducting layer 321 extends along the axial direction of the liquid-conducting element 30; when unwound, the third indentation pattern of the liquid-conducting layer 321 extends along the width direction, and the second indentation pattern on the heated layer 322 extends along the length direction.

The liquid-conducting layer 316 is a deceleration layer used to reduce or slow down the rate at which the liquid matrix is ​​transferred from the liquid-conducting layer 312 to the heating layer 322. The liquid conduction rate of the liquid-conducting layer 316 is lower than that of the first rapidly conducting liquid layer, such as liquid-conducting layer 311, and / or the second rapidly conducting liquid layer, such as liquid-conducting layer 312.

[0180] In some embodiments, the liquid-conducting layer 316, serving as a deceleration layer, is prepared from flax, Australian cotton, or nylon fibers with a lower liquid conduction rate than wood pulp fibers and / or silk fibers. Alternatively, the liquid-conducting layer 316, serving as a deceleration layer, is a flax fiber layer, an Australian cotton fiber layer, or a nylon fiber layer. In some embodiments, the liquid-conducting layer 316 has a liquid conduction rate of 70 g / m³. 2 Up to 90g / m 2 The basis weight; in some specific embodiments, the basis weight of the liquid guiding layer 316 is 75 g / m³. 2 .

Furthermore, after winding, the fourth indentation pattern extends circumferentially along the fluid guiding element 30.

[0182] In some embodiments, the fluid guiding element 30 further includes at least:

[0183] At least one or more liquid guiding layers, such as liquid guiding layers 317, 318, 319 and 320, which are also used for flavor and / or sweetness adjustment, are arranged between liquid guiding layer 316, which serves as a deceleration layer and heating layer 322; or, more specifically, liquid guiding layers, such as liquid guiding layers 317, 318, 319 and 320, which are also used for flavor and / or sweetness adjustment, are arranged between liquid guiding layer 316 of the deceleration layer and liquid guiding layer 321 of the deceleration layer.

[0184] In embodiments, these flavor and / or sweetness-modifying liquid-conducting layers, such as liquid-conducting layers 317, 318, 319, and 320, are advantageous in adsorbing or filtering the components of flavorings and / or flavor additives in a liquid matrix, thereby enhancing or improving the flavor or sweetness of the aerosols atomized from the heated layer 322.

[0186] In some embodiments, the liquid guiding layers with flavor and / or sweetness adjustment, such as liquid guiding layers 317, 318, 319 and 320, are not mesh-like.

[0187] In some embodiments, the liquid guiding layers 317, 318, and 319, which have flavor and / or sweetness adjustment, include a fifth indentation pattern disposed thereon; the fifth indentation pattern is curved and corrugated. After winding, the fifth indentation pattern forms an angle with both the axial and circumferential directions of the liquid guiding element 30. The liquid guiding layer 320, which has flavor and / or sweetness adjustment, has a sixth indentation pattern; after winding, the sixth indentation pattern on the liquid guiding layer 320 extends circumferentially along the liquid guiding element 30.

[0188] In some embodiments, the temperature resistance of liquid-conducting layer 320, which has fragrance and / or sweetness adjustment, is greater than that of liquid-conducting layers 317, 318, or 319. In some specific embodiments, liquid-conducting layer 320 is made of nylon fibers that can withstand temperatures of at least 150°C; liquid-conducting layers 317, 318, or 319 are made of cotton fibers or nonwoven fibers with lower temperature resistance than nylon fibers.

[0189] The following shows the test results of the liquid guiding element 30 with the above 12 liquid guiding layers in the use of the atomizer 100 in some embodiments; wherein the test is to inject e-liquid into the 3mL capacity reservoir 12 of the atomizer 100, and then perform vaping tests at a predetermined frequency for 3 days until the e-liquid is consumed within 3 days, and then collect various vaping data and leakage / dry burning data of the atomizer 100 product.

[0190]

[0191]

[0192] Based on the test results of the numerous samples above, the liquid guiding element 30, which has a fast liquid guiding layer, a deceleration layer such as liquid guiding layer 316, and a liquid storage layer such as liquid guiding layer 321, can basically deliver e-liquid to the innermost heating layer 322 in a balanced manner during use. It avoids issues of splattering and leakage, as well as dry burning and burnt coils. Furthermore, the liquid guiding element 30 with flavor and / or sweetness adjustment layers such as liquid guiding layers 317, 318, 319, and 320 maintains a relatively balanced aroma throughout each puff, with no significant decrease in aroma or flavor, at least in the latter part of the puff.
