Description

Technical Field

[0002] At present, the liquid guide parts used in electronic atomization devices are mostly made of oil-conducting cotton wrapped around the heating wire. The liquid guide parts are generally made of natural cellulose or regenerated cellulose, such as cotton fiber, hemp fiber, bamboo fiber, viscose fiber, lyocell fiber, etc. These fiber materials generally have insufficient heat resistance. When the temperature of the heating wire exceeds 250°C, there will be obvious decomposition and carbonization. Some fiber materials will even decompose and carbonize at around 200°C, and the heat resistance is poor. After the fiber is carbonized, the surface composition and structure of the liquid guide parts are changed, which greatly affects its liquid guide performance, causing the atomization core to fail, and then the suction taste of the electronic atomization device will become worse, and the life span will also be greatly reduced.

[0030] See also Figure 1 to Figure 2 Some embodiments of the present application provide a liquid guiding member for use in an electronic atomization device (not shown), wherein the liquid guiding member includes at least one layer of heat-resistant fiber cotton layer 1, and at least one side of the liquid guiding member is composed of the heat-resistant fiber cotton layer 1.

[0031] The heat-resistant fiber cotton layer 1 of the liquid-conducting component of the present application has a thermal decomposition temperature of ≥400° C., a moisture regain of ≥5%, and a porosity of ≥85%.

[0032] The liquid-conducting part provided by the present application is composed of a heat-resistant fiber cotton layer 1 on at least one side. When in use, the side with the heat-resistant fiber cotton layer can directly contact the heating element of the electronic atomization device, and the thermal decomposition temperature of the heat-resistant fiber cotton layer reaches above 400°C, ensuring that the heat-resistant fiber cotton layer will not be easily decomposed and carbonized at around 400°C, significantly improving the heat resistance of the liquid-conducting part, ensuring the liquid-conducting effect, and improving the atomization suction taste. Moreover, the moisture regain of the heat-resistant fiber cotton layer of the liquid-conducting part provided by the present application is above 5% and the porosity is above 85%, so that the heat-resistant fiber cotton layer has good wettability with the atomization matrix, which can meet the requirements of the transmission and liquid-conducting performance of the atomization matrix under high temperature (above 300°C), and improve the efficiency of the heat-resistant fiber cotton layer in adsorbing and transmitting the atomization matrix, thereby improving the atomization effect of the atomization core under high temperature conditions, and ensuring the atomization suction taste of the electronic cigarette. In addition, the liquid guide member provided in the present application can directly contact the heating element of the electronic atomization device through its side having the heat-resistant fiber cotton layer. Under the same atomization conditions, the liquid guide member of the present application has a longer service life and can withstand the use requirements of the atomization device at higher power.

[0033] In some embodiments, the heat-resistant fiber cotton layer 1 of the liquid-conducting component of the present application is an aromatic sulfone fiber cotton layer, a polybenzimidazole fiber cotton layer, or a polybenzimidazole-aromatic ether sulfone fiber cotton layer.

[0034] It can be understood that the heat-resistant fiber cotton layer 1 of the liquid-conducting component can be provided with only one layer or multiple layers. The multiple layers of heat-resistant fiber cotton layers 1 can be fiber cotton layers of the same kind or fiber cotton layers of different kinds. The multiple layers of heat-resistant fiber cotton layers 1 can be stacked in sequence of the same kind or different kinds, or can be arranged at intervals of the same kind. The present application does not make any limitation on this. It is sufficient to ensure that at least one side of the liquid-conducting component is composed of the heat-resistant fiber cotton layer 1 and contacts the heating element through the heat-resistant fiber cotton layer 1.

[0035] The liquid-conducting part provided in the present application directly contacts the heating element of the atomizing device through the heat-resistant fiber cotton layer 1, and the heat-resistant fiber cotton layer 1 includes at least one of an aromatic sulfone fiber cotton layer, a polybenzimidazole fiber cotton layer, and a polybenzimidazole-aromatic ether sulfone fiber cotton layer, so that the heat-resistant fiber cotton layer 1 has the high-temperature resistance of one or more of the above-mentioned synthetic fibers, and can increase the thermal decomposition temperature of the heat-resistant fiber cotton layer 1 to above 400°C, ensuring that the heat-resistant fiber cotton layer 1 will not easily decompose and carbonize at around 400°C, thereby improving the heat resistance of the liquid-conducting part, ensuring the liquid-conducting effect, and improving the atomizing suction taste. Moreover, the high-temperature resistant fiber cotton layer of the liquid-conducting part provided in the present application has good wettability with the atomizing matrix, which can meet the requirements for the transmission and liquid-conducting performance of the atomizing matrix under high temperature (above 300°C), ensuring the liquid-conducting and atomizing effects. In addition, the liquid guide member provided in the present application directly contacts the heating element of the atomization device through the heat-resistant fiber cotton layer 1. Under the same atomization conditions, the liquid guide member of the present application has a longer service life and can withstand the use requirements of the atomization device at higher power.

[0036] In some embodiments, the aramid fiber cotton layer is made of aramid fiber, and its molecular structure includes

[0037] At least one of; wherein, the value range of n1-n5 is between 50 and 200, and the value range of m is between 50 and 200. When the heat-resistant fiber cotton layer 1 of the liquid-conducting part of the present application is made of aromatic sulfone fiber, the number of repeating units in its molecular structure is controlled between 50 and 200, which can bring better heat resistance and ensure that the liquid-conducting part will not easily decompose and carbonize at about 400°C.

[0038] In some embodiments, the aramid fiber cotton layer may contain only one of the structures in the above-mentioned aramid fiber molecular structure formula, or may contain two or more structures at the same time, and this application does not limit this. When the aramid fiber cotton layer contains multiple structures in the above-mentioned aramid fiber molecular structure formula, the content and addition ratio of each aramid fiber molecular structure in the heat-resistant fiber cotton layer 1 can be adjusted accordingly based on the corresponding characteristics of each fiber molecular structure and the actual needs of the liquid guide, and this application does not limit this.

[0039] Aromatic sulfone fiber is composed of polysulfoneamide. When heated in hot air at 300°C for 100 hours, the strength loss is less than 5%. It has excellent electrical insulation and heat resistance, high flame retardancy, a limiting oxygen index of more than 30%, and good chemical stability. It is an excellent special heat-resistant fiber material. The heat-resistant fiber cotton layer 1 is set as an aromatic sulfone fiber cotton layer, which can ensure that the liquid-conducting part will not undergo obvious decomposition and carbonization at an atomization temperature of about 400°C, thereby improving the high temperature resistance of the liquid-conducting part of the present application. In addition, the wettability of the aromatic sulfone fiber cotton layer is higher than that of the aramid fiber cotton layer, which can meet the requirements of the transmission and liquid-conducting performance of the atomization matrix under high temperature conditions, ensure the liquid-conducting and atomization effects, improve its service life and withstand the use requirements of the atomization device at higher power.

[0040] In some embodiments, the polybenzimidazole fiber cotton layer is made of polybenzimidazole fiber, and its molecular structure includes Among them, the value range of n6 is between 65 and 200. When the heat-resistant fiber cotton layer 1 of the liquid-conducting part of the present application is made of polybenzimidazole fiber, the number of repeating units in its molecular structure is controlled between 65 and 200, which can bring better heat resistance and ensure that the liquid-conducting part will not easily decompose and carbonize at about 400°C.

[0041] Polybenzimidazole fiber is a heterocyclic polymer heat-resistant fiber that is non-flammable in air and burns slowly in oxygen. It still has good structural stability under flames and high temperatures (300°C), can be used for a short time at 500°C, and has good wettability and chemical stability. It is an excellent special heat-resistant fiber material. The heat-resistant fiber cotton layer 1 is set as a polybenzimidazole fiber cotton layer, which can ensure that the liquid guide part will not undergo obvious decomposition and carbonization at an atomization temperature of about 400°C, thereby improving the heat resistance and liquid conduction performance of the liquid guide part of the present application, and improving its service life and the ability to withstand the use requirements of the atomization device at higher power.

[0042] In some embodiments, the polybenzimidazole-aryl ether sulfone fiber cotton layer is made of polybenzimidazole-aryl ether sulfone fiber, and its molecular structure includes Among them, the value range of n7 is between 60 and 150. When the heat-resistant fiber cotton layer 1 of the liquid-conducting part of the present application is made of polybenzimidazole-aryl ether sulfone fiber, the number of repeating units in its molecular structure is controlled between 60 and 150, which can bring better heat resistance and ensure that the liquid-conducting part will not easily decompose and carbonize at about 400°C.

[0043] The repeating units of polybenzimidazole-aryl ether sulfone fiber contain both polybenzimidazole and aryl ether sulfone, and have the characteristics of both polybenzimidazole and aryl ether sulfone, so that it has good high temperature stability, chemical stability and wettability, and higher mechanical strength, and is an excellent special heat-resistant fiber material. The heat-resistant fiber cotton layer 1 is set as a polybenzimidazole-aryl ether sulfone fiber cotton layer, which can ensure that the liquid guide part will not undergo obvious decomposition and carbonization at an atomization temperature of about 400°C, thereby improving the heat resistance and liquid conduction performance of the liquid guide part of the present application, and also significantly improving the mechanical strength of the liquid guide part, increasing its service life and the requirement to withstand the use of the atomization device at higher power.

[0044] The thickness of the heat-resistant fiber cotton layer 1 is preferably not less than 0.2 mm to ensure that the heat-resistant fiber cotton layer 1 has sufficient thickness to withstand the high temperature of the heating element without decomposition and carbonization.

[0045] In some embodiments, the liquid guide of the present application is an integrated structure, which is composed of a single layer of heat-resistant fiber cotton layer 1, that is, the entire liquid guide is a single layer of thickened heat-resistant fiber cotton. Alternatively, the liquid guide of the present application can also be an integrated structure formed by stacking multiple layers of heat-resistant fiber cotton layers 1 in sequence, that is, multiple layers of heat-resistant fiber cotton layers 1 are stacked and fixed as a whole.

[0046] In some other embodiments, the liquid-conducting component of the present application can be configured as a split structure, formed by stacking multiple layers of heat-resistant fiber cotton layers 1.

[0047] The liquid-conducting component of the present application can be an integrated structure consisting of a single-layer thickened heat-resistant fiber cotton layer 1, or an integrated structure consisting of multiple layers of heat-resistant fiber cotton layers 1 stacked on top of each other, and the present application does not make any limitation on this.

[0048] The integrated structure of the liquid guide piece is easy to process into various shapes to adapt to the atomizer cores of different structures of the atomizer device. When the liquid guide piece is an integrated structure composed entirely of the heat-resistant fiber cotton layer 1, its two opposite sides are both composed of the heat-resistant fiber cotton layer 1, so that any one of the two opposite sides of the liquid guide piece can be used as an atomization surface and directly contact the heating element, and even the heating element can be arranged on the two opposite sides of the liquid guide piece at the same time, so that the contact position between the liquid guide piece and the heating element is more flexible, and the diversity of the atomizer core structure design is improved.

[0049] The liquid-guiding component with a split structure can adaptively adjust the type, thickness, and stacking method of each layer of heat-resistant fiber cotton layer according to the structural design of different atomizer cores and actual atomization requirements, thereby flexibly changing the overall liquid-guiding performance and atomization effect of the liquid-guiding component to meet the use requirements of different types of atomization devices.

[0050] When the liquid-conducting component has multiple layers of heat-resistant fiber cotton layers, each layer can be all aromatic sulfone fiber cotton layers, or all polybenzimidazole fiber cotton layers, or all polybenzimidazole-aromatic ether sulfone fiber cotton layers, that is, the multiple layers of heat-resistant fiber cotton layers of the liquid-conducting component can be the same special fiber cotton layers.

[0051] In some embodiments, the multiple layers of heat-resistant fiber cotton layers of the liquid-conducting part can also be different types of special fiber cotton layers. For example, the liquid-conducting part can have both an aromatic sulfone fiber cotton layer and a polybenzimidazole fiber cotton layer; or the liquid-conducting part has both an aromatic sulfone fiber cotton layer and a polybenzimidazole-aryl ether sulfone fiber cotton layer; or the liquid-conducting part has both a polybenzimidazole fiber cotton layer and a polybenzimidazole-aryl ether sulfone fiber cotton layer; or the liquid-conducting part has both an aromatic sulfone fiber cotton layer, a polybenzimidazole fiber cotton layer, and a polybenzimidazole-aryl ether sulfone fiber cotton layer. As to whether the different types of heat-resistant fiber cotton layers are stacked in sequence of the same type or different types, this application does not limit this, and can be adjusted accordingly according to the different liquid-conducting properties of the liquid-conducting part and the requirements of atomization use.

[0052] For example, the heat-resistant fiber cotton layer 1 on the side of the liquid-conducting part contacting the heating element can be set to a polybenzimidazole-aryl ether sulfone fiber cotton layer, after which the polybenzimidazole-aryl ether sulfone fiber cotton layer can be continuously stacked, or the aromatic sulfone fiber cotton layer or the polybenzimidazole fiber cotton layer can be stacked. Alternatively, the heat-resistant fiber cotton layer 1 on the side of the liquid-conducting part contacting the heating element can also be set to a polybenzimidazole fiber cotton layer, after which the polybenzimidazole fiber cotton layer can be continuously stacked, or the aromatic sulfone fiber cotton layer or the polybenzimidazole-aryl ether sulfone fiber cotton layer can be stacked. Alternatively, the heat-resistant fiber cotton layer 1 on the side of the liquid-conducting part contacting the heating element can also be set to an aromatic sulfone fiber cotton layer, after which the aromatic sulfone fiber cotton layer can be continuously stacked, or the polybenzimidazole fiber cotton layer or the polybenzimidazole-aryl ether sulfone fiber cotton layer can be stacked.

[0053] See also Figure 1 to Figure 2 In some embodiments, the liquid conducting member of the present application further comprises at least one layer of liquid conducting fiber cotton layer 2, and the liquid conducting fiber cotton layer 2 is stacked with the heat-resistant fiber cotton layer 1. The liquid conducting fiber cotton layer 2 is a natural cellulose fiber cotton layer or a regenerated cellulose fiber cotton layer.

[0054] The liquid-conducting fiber cotton layer 2 is set as a natural cellulose fiber cotton layer or a regenerated cellulose fiber cotton layer. Compared with the heat-resistant fiber cotton layer 1, its heat resistance is relatively poor. It will decompose and carbonize when in direct contact with the heating element under high temperature conditions of 300°C. It is not suitable as an atomization layer of the liquid-conducting element to directly contact the heating element. However, its wettability to the atomization matrix is ​​higher than that of the heat-resistant fiber cotton layer 1, the liquid-conducting effect is better, and the production and manufacturing costs are relatively lower, which is suitable for large-scale use.

[0055] Natural cellulose fibers include plant fibers and animal fibers. Common plant fibers include but are not limited to hemp fibers, cotton fibers, mercerized cotton fibers, bamboo fibers, etc., and animal fibers include silk, wool, etc. Common regenerated cellulose fibers include but are not limited to viscose fibers, strong fibers, modal fibers, lyocell fibers, velvet fibers, cuprammonium fibers, etc. The fiber material of the liquid-conducting fiber cotton layer 2 of the liquid-conducting part of the present application can be selected accordingly according to actual use requirements, and the present application does not limit this. The above-mentioned natural and regenerated fiber materials can have a good infiltration effect with the atomization matrix, and after being made into a hollow structure fiber, the liquid storage capacity and liquid conduction effect of the liquid-conducting fiber cotton layer can be further improved.

[0056] In some embodiments, the moisture regain of the liquid-conducting fiber cotton layer 2 is ≥10%, and the porosity is ≥90%.

[0057] The liquid-conducting fiber cotton layer 2 of the liquid-conducting component provided in the present application has good wettability. On this basis, combined with the optimized selection of the regain and porosity of the liquid-conducting fiber cotton layer 2 in the present application, the liquid-conducting fiber cotton layer 2 of the liquid-conducting component of the present application has better wettability and liquid-conducting performance than the heat-resistant fiber cotton layer 1, further improving the overall liquid-conducting capacity of the liquid-conducting component and achieving a better atomization effect.

[0058] See also Figures 3 to 5 The liquid-conducting component provided by the present application comprises a liquid-conducting fiber cotton layer 2, the fiber of which is a hollow structural fiber 20. The interior of the hollow structural fiber 20 is provided with at least one channel 201 axially penetrating therein. The channel 201 inside the fiber plays a role in storing atomized matrix and rapidly transmitting atomized matrix along the channel direction during the liquid-conducting process, and can significantly improve the porosity of the liquid-conducting fiber cotton layer 2 and increase the liquid storage capacity. Combined with the present application's optimized selection of the regain and porosity of the liquid-conducting fiber cotton layer 2, the liquid-conducting fiber cotton layer 2 of the liquid-conducting component of the present application has better wettability and liquid-conducting performance, can absorb and store more atomized matrix during the liquid-conducting process, and has a faster liquid-conducting speed and higher efficiency, thereby satisfying the atomized matrix supply demand when the atomizing device is inhaled in large gulps, and improving the atomized suction taste.

[0059] See also Figures 3 to 5 The hollow structural fibers 20 constituting the liquid-conducting fiber cotton layer 2 of the present application may be hollow cylindrical fibers (such as Figure 4), or a hollow regular or irregular strip-shaped polyhedral fiber, wherein a single fiber may have only one channel 201 penetrating the fiber body (as shown in Figure 3 and Figure 4 ), and may also have multiple channels 201 that penetrate the fiber body (as shown in Figure 5 As shown in ), the channels 201 may be arranged in parallel or partially cross-connected, which is not limited in the present application.

[0060] It can be understood that the more channels 201 there are inside the hollow structural fiber 20, the more atomized matrix can be stored under the same volume, and the porosity of the liquid-conducting fiber cotton layer 2 and the wettability to the atomized matrix can be further improved, thereby bringing better liquid storage and liquid conduction effects.

[0061] The liquid-conducting component of the present application includes at least one layer of liquid-conducting fiber cotton layer 2. The single-layer or multi-layer liquid-conducting fiber cotton layer 2 absorbs the atomized matrix and evenly and efficiently transfers the atomized matrix to the heat-resistant fiber cotton layer 1 and the heating element. Compared with the design of completely adopting the high-temperature resistant fiber layer, it not only improves the liquid storage capacity and liquid conduction efficiency of the liquid-conducting component and ensures the atomization and smoking effect of the electronic cigarette, but also can significantly reduce the manufacturing cost of the liquid-conducting component, thereby reducing the selling price of the atomizing core and the atomizing device used therewith, which is conducive to improving the market competitiveness of electronic cigarette products.

[0062] In some embodiments, the liquid-conducting fiber cotton layer 2 and the heat-resistant fiber cotton layer 1 can be stacked as a liquid-conducting part with an integral structure or a liquid-conducting part with a split structure. This application does not limit this, as long as it meets the actual use needs. For example, one side of the liquid-conducting part can be set to one or more layers of the heat-resistant fiber cotton layer 1, the middle part of the liquid-conducting part can be stacked with a layer of liquid-conducting fiber cotton layer 2 or multiple layers of liquid-conducting fiber cotton layers 2 can be stacked in sequence, and the other side of the liquid-conducting part can also be set to one or more layers of the heat-resistant fiber cotton layer 1. In this way, a liquid-conducting part with an integral structure or a split structure having heat-resistant fiber cotton layers 1 on both sides can be formed, so that both sides of the liquid-conducting part can be used as atomizing surfaces to directly contact the heating element.

[0063] In some embodiments, one side of the liquid-conducting component can also be set as one or more layers of heat-resistant fiber cotton layer 1, and then a layer of liquid-conducting fiber cotton layer 2 is stacked or multiple layers of liquid-conducting fiber cotton layer 2 are stacked in sequence, so that the other side of the liquid-conducting component is composed of liquid-conducting fiber cotton layer 2. In this way, a liquid-conducting component with a one-piece structure or a split structure having a heat-resistant fiber cotton layer 1 on one side can be formed, and the liquid-conducting component uses one side with the heat-resistant fiber cotton layer 1 as the atomizing surface and directly contacts the heating element, and the other side of the liquid-conducting component with the liquid-conducting fiber cotton layer 2 can be used as a liquid inlet surface for adsorbing the atomized matrix, and the atomized matrix is ​​evenly and efficiently transmitted to the heat-resistant fiber cotton layer 1 and the heating element through the single or multiple layers of liquid-conducting fiber cotton layer 2.

[0064] The side of the liquid-conducting part that contacts the heating element is preferably stacked with two or more layers of heat-resistant fiber cotton layers 1, so that the side of the liquid-conducting part that contacts the heating element can ensure better heat resistance. Of course, the more layers of heat-resistant fiber cotton layers 1 are set, the higher the cost. Therefore, under the premise of meeting the heat resistance requirements, the number of layers of heat-resistant fiber cotton layers 1 in the liquid-conducting part can be minimized. Of course, multiple layers of heat-resistant fiber cotton layers can also be replaced with a single-layer thickened heat-resistant fiber cotton layer, so that the single-layer thickened heat-resistant fiber cotton layer has the same heat resistance and liquid-conducting effect as the multiple layers of heat-resistant fiber cotton layers.

[0065] In some embodiments, the porosity of the liquid-conducting fiber cotton layer 2 is preferably above 93%. Since the liquid-conducting fiber cotton layer 2 is made of hollow structural fibers 20, it has good wettability and good adsorption and transmission capabilities for the atomized matrix. Combined with the optimization of the porosity of the liquid-conducting fiber cotton layer 2 itself in the present application, the wettability and liquid-conducting efficiency of the liquid-conducting fiber cotton layer 2 can be further improved, thereby improving its ability to adsorb and transmit the atomized matrix, bringing better liquid-conducting effects.

[0066] In some embodiments, the liquid-conducting component of the present application is an integrated structure formed by stacking a heat-resistant fiber cotton layer 1 and a liquid-conducting fiber cotton layer 2, or is a separate structure formed by stacking a heat-resistant fiber cotton layer 1 and a liquid-conducting fiber cotton layer 2.

[0067] The integrated structure of the liquid guide is not only easy to process into various shapes to adapt to the atomizer cores of different structures of the atomizer device, but also can reduce the risk of the liquid guide falling off between layers during installation, transportation, and use, thereby improving the production yield and working stability of the atomizer core of the atomizer device. In addition, the integrated structure of the liquid guide is easy to control the consistency of product thickness and gram weight, reducing the risk of core sticking caused by uneven thickness of the liquid guide, which is conducive to extending the service life of the liquid guide.

[0068] The liquid-conducting component with a split structure can achieve various changes in the overlapping methods between layers. On the one hand, according to the structural characteristics of the atomizer core, the overall thickness of the liquid-conducting component can be adjusted by adding or reducing the heat-resistant fiber cotton layer 1 or the liquid-conducting fiber cotton layer 2, thereby improving the adaptability of the liquid-conducting component to different atomizer cores. On the other hand, the heat resistance, wettability, liquid storage performance, liquid conduction performance and mechanical strength of the overall liquid-conducting component can be adjusted by multiple overlapping methods of different types of fiber cotton layers between the multiple layers of heat-resistant fiber cotton layers 1 and the multiple layers of liquid-conducting fiber cotton layers 2, thereby achieving variable adjustment of the characteristics of the liquid-conducting component to adapt to the atomization usage requirements of different atomization devices.

[0069] See also Figure 6 to Figure 7In some embodiments, at least one side of the liquid-conducting fiber cotton layer 2 is provided with convex or concave overall horizontal or vertical lines 21, and these lines 21 and the surface of the adjacent liquid-conducting fiber cotton layer 2 or the lines 21, or between the surface of the adjacent heat-resistant fiber cotton layer 1, or between the surface of the adjacent liquid-conducting fiber cotton layer 2 or the lines 21 and the surface of the adjacent heat-resistant fiber cotton layer 1, form an overall horizontal or vertical or mesh liquid-conducting groove.

[0070] It can be understood that the overall horizontal or vertical lines 21 can be set only on one side of the liquid-conducting fiber cotton layer 2, or can be set on two opposite sides of the liquid-conducting fiber cotton layer 2 at the same time; the lines 21 on the opposite sides of the same liquid-conducting fiber cotton layer 2 can be the same or different, and this application does not limit this. The overall vertical lines 21 refer to the lines 21 on the surface of the liquid-conducting fiber cotton layer 2 as a whole extending from the upper end to the lower end, but it is not required that each line 21 is set from top to bottom, and it can also be a branch line 21 extending outward on the basis of the vertical lines 21, or it can be a vertical line 21 and a horizontal line 21 staggered arrangement. The overall horizontal lines 21 refer to the lines 21 on the surface of the liquid-conducting fiber cotton layer 2 as a whole extending from the left side to the right side, but it is not required that each line 21 is set from left to right, and it can also be a branch line 21 extending outward on the basis of the horizontal lines 21, or it can be a vertical line 21 and a horizontal line 21 staggered arrangement.

[0071] Due to the different arrangements of the patterns 21, the liquid-conducting fiber cotton layer 2 can be roughly divided into a vertical-line liquid-conducting fiber cotton layer 2 and a horizontal-line liquid-conducting fiber cotton layer 2. These two types of liquid-conducting fiber cotton layers 2 with different pattern 21 characteristics can be combined in a variety of different overlapping ways to form liquid-conducting parts with different liquid-conducting groove characteristics, thereby achieving variable adjustment of the liquid-conducting performance of the liquid-conducting parts.

[0072] Since the lines 21 are convexly or concavely arranged on the surface of the liquid-conducting fiber cotton layer 2, after two adjacent layers of liquid-conducting fiber cotton or the liquid-conducting fiber cotton layer 2 and the adjacent heat-resistant fiber cotton layer 1 are superimposed, the lines 21 and the fiber cotton layer surface, or the lines 21 and the lines 21, will be superimposed to form an overall horizontal or vertical or mesh liquid-conducting groove. In this way, different forms of liquid-conducting grooves will be formed between multiple layers of liquid-conducting fiber cotton layers 2, or between the liquid-conducting fiber cotton layer 2 and the adjacent heat-resistant fiber cotton layer 1 due to different superposition methods. These liquid-conducting grooves can not only store more atomized substrates, but also can quickly and efficiently transfer the atomized substrates to different positions of the liquid-conducting parts based on the extension path and arrangement characteristics of the liquid-conducting grooves, thereby significantly improving the liquid-conducting uniformity and liquid-conducting efficiency of the liquid-conducting parts, thereby improving the atomization and smoking effect of the atomization core, and improving the atomization and smoking taste of the electronic cigarette.

[0073] The lines 21 on the liquid-conducting fiber cotton layer 2 are in the same direction and arranged regularly, that is, the lines 21 are repeating units with a certain regular arrangement, or the lines 21 of the liquid-conducting fiber cotton layer 2 are in the same direction overall. This makes it possible to use simpler technical means to achieve the desired lines 21 when preparing the lines 21 of the liquid-conducting fiber cotton layer 2, and it is also simpler to stack multiple layers of liquid-conducting fiber cotton layers 2, thereby saving production costs.

[0074] See also Figure 6 to Figure 7 In some embodiments, the heat-resistant fiber cotton layer 1 of the liquid guide of the present application is provided with an embedding groove 11 on one side contacting the heating element, and the heating element is at least partially embedded in the embedding groove 11. The liquid guide of the present application fixes and embeds the heating element through the embedding groove 11 provided on the heat-resistant fiber cotton layer 1. On the one hand, it can improve the reliability and stability of the fixed contact between the liquid guide and the heating element, prevent the heating element from being separated from the liquid guide in the event of vibration or falling, and ensure the reliability of the use of the atomization core. On the other hand, it can also increase the effective contact area between the liquid guide and the heating part of the heating element, thereby increasing the atomization amount of the atomization matrix per unit time, improving the richness of the atomization smoke of the atomization matrix, and then improving the atomization smoking taste.

[0075] It can be understood that the engaging grooves 11 can be provided on all the heat-resistant fiber cotton layers 1 of the liquid-conducting component, thereby achieving the structural consistency of the heat-resistant fiber cotton layers 1 and facilitating the overlapping of the liquid-conducting component.

[0076] See also Figure 7 In some embodiments, a plurality of liquid conducting blind holes 12 are arranged on the heat-resistant fiber cotton layer 1 of the liquid conducting component of the present application, and these liquid conducting blind holes 12 extend from the side of the heat-resistant fiber cotton layer 1 away from the heating element to the inside of the heat-resistant fiber cotton layer 1.

[0077] The heat-resistant fiber cotton layer 1 of the liquid-conducting part of the present application is provided with liquid-conducting blind holes 12, which can further improve the wettability and improve the liquid storage and liquid-conducting capabilities of the heat-resistant fiber cotton layer 1. Because the liquid-conducting blind holes 12 extend from the side away from the heating element to the inside of the heat-resistant fiber cotton layer 1, the atomized matrix on the liquid-conducting fiber cotton layer 2 can be directly and efficiently transmitted to the atomizing surface side of the liquid-conducting part through each liquid-conducting blind hole 12, thereby improving the liquid-conducting efficiency, increasing the atomization amount of the atomized matrix per unit time, improving the richness of the atomized smoke, and thus improving the atomized smoking taste. In addition, the liquid guide blind hole 12 is a hole that does not completely penetrate the two opposite sides of the heat-resistant fiber cotton layer 1. It extends inward from the side facing away from the heating element, so that the liquid guide blind hole 12 will not destroy the structural consistency of the side of the heat-resistant fiber cotton layer 1 that contacts the heating element, and can play a "oil locking" effect on the atomized matrix, preventing excessive atomized matrix from leaking to the atomizing surface side of the liquid guide component through the liquid guide blind hole 12, avoiding "oil leakage" of the atomization core, and preventing the unatomized atomized matrix from being sucked into the mouth of the smoker along with the atomized smoke, thereby ensuring the atomization effect and improving the smoking taste.

[0078] The liquid-conducting blind holes 12 can be evenly distributed on the heat-resistant fiber cotton layer 1, so that the atomized matrix on the liquid-conducting fiber cotton layer 2 can be evenly distributed on the heat-resistant fiber cotton layer 1 through these liquid-conducting blind holes 12, so as to improve the overall liquid-conducting uniformity of the liquid-conducting component. In addition, the liquid-conducting blind holes 12 can also be designed to be compatible with the extension and arrangement characteristics of the liquid-conducting grooves formed by the lines 21 between the heat-resistant fiber cotton layer 1 and the liquid-conducting fiber cotton layer 2, so that the atomized matrix in the liquid-conducting grooves between the heat-resistant fiber cotton layer 1 and the liquid-conducting fiber cotton layer 2 can be directly transferred to the heat-resistant fiber cotton layer 1 through the corresponding liquid-conducting blind holes 12, thereby improving the efficiency of the atomized matrix being transmitted to the atomizing surface side of the liquid-conducting component and increasing the atomization amount of the atomized matrix per unit time.

[0079] It can be understood that the liquid conducting blind hole 12 can be set to extend inwardly perpendicular to the surface of the heat-resistant fiber cotton layer 1, or can be set to extend inwardly in an inclined manner. The present application does not limit this, as long as the use requirements are met.

[0080] See also Figures 8 to 9 In some embodiments, the liquid guide member of the present application further includes at least one layer of liquid-absorbing fiber cotton layer 3, and the liquid-absorbing fiber cotton layer 3 is sequentially stacked with the liquid-conducting fiber cotton layer 2 and the heat-resistant fiber cotton layer 1, so that the liquid-conducting fiber cotton layer 2 is located between the heat-resistant fiber cotton layer 1 and the liquid-absorbing fiber cotton layer 3. That is, the liquid guide member of the present application is substantially composed of three parts: a stacked high-temperature resistant part (composed of the heat-resistant fiber cotton layer 1 stacked in sequence), an intermediate part (composed of the liquid-conducting fiber cotton layer 2 stacked in sequence), and a liquid-absorbing part (composed of the liquid-absorbing fiber cotton layer 3 stacked in sequence).

[0081] The liquid-absorbent fiber cotton layer 3 is made of natural cellulose fibers or regenerated cellulose fibers.

[0082] In some embodiments, the moisture regain of the liquid-absorbent fiber cotton layer is ≥12% and the porosity is ≥85%.

[0083] The liquid-conducting component of the present application contacts the heating element with the outer surface of its high-temperature resistant part having the heat-resistant fiber cotton layer 1, contacts and absorbs the atomized matrix with the outer surface of its liquid-absorbing part having the liquid-absorbing fiber cotton layer 3, connects the liquid-absorbing part and the high-temperature resistant part of the liquid-conducting component with its middle part having the liquid-conducting fiber cotton layer 2, and acts as an intermediate medium to transfer the atomized matrix adsorbed by the liquid-absorbing fiber cotton layer 3 to the heat-resistant fiber cotton layer 1.

[0084] The liquid-absorbing fiber cotton layer 3 of the liquid-conducting component of the present application is made of natural or regenerated cellulose fibers, so that the liquid-absorbing fiber cotton layer 3 has good wettability to the atomized matrix, can quickly and efficiently absorb the atomized matrix through the liquid-absorbing part, and transfer the atomized matrix to the liquid-conducting fiber cotton layer 2 in the middle part, and then under the liquid storage and liquid-conducting effects of the liquid-conducting fiber cotton layer 2, a sufficient amount of atomized matrix is ​​transferred to the heat-resistant fiber cotton layer 1 in the high-temperature resistant part in a shorter time for heating and atomization, thereby further improving the liquid-conducting efficiency and atomization effect of the liquid-conducting component of the present application.

[0085] Natural cellulose fibers include plant fibers and animal fibers. Common plant fibers include but are not limited to hemp fibers, cotton fibers, mercerized cotton fibers, bamboo fibers, etc., and animal fibers include silk, wool, etc. Common regenerated cellulose fibers include but are not limited to viscose fibers, strong fibers, modal fibers, lyocell fibers, velvet fibers, cuprammonium fibers, etc. As for which fiber material is specifically selected to make the liquid-absorbing fiber cotton layer 3, it can be selected accordingly according to actual use requirements, and this application does not limit this. The above-mentioned fiber materials can have a good infiltration effect with the atomized matrix, which can ensure that the liquid-absorbing fiber cotton layer 3 has a good infiltration effect.

[0086] It can be understood that the heat-resistant fiber cotton layer 1, the liquid-conducting fiber cotton layer 2 and the liquid-absorbent fiber cotton layer 3 can be either spunlace cotton or needle-punched cotton. This application does not limit this, as long as it meets the actual use needs.

[0087] See also Figures 10 to 12 In some embodiments, the liquid-absorbent fiber cotton layer 3 is made of solid structural fibers 30. The solid structural fibers 30 may be solid cylindrical fibers (not shown) or solid regular or irregular strip-shaped polyhedral fibers, which is not limited in the present application.

[0088] The cross section of a single solid structural fiber 30 is preferably cross-shaped (eg Fig.10 ), trilobate (as shown in Fig.11 ), pentagonal (as shown in Fig.12 The solid structural fibers 30 constituting the liquid-absorbent fiber cotton layer 3 have at least one axially extending protrusion (not shown) on the outside, so that the solid structural fibers 30 have a larger surface area than ordinary cylindrical fibers, thereby enabling the liquid-absorbent fiber cotton layer 3 of the liquid-conducting component of the present application to absorb more atomized matrix per unit time and have better liquid absorption performance.

[0089] In some embodiments, the porosity of the liquid-absorbing fiber cotton layer 3 of the liquid-conducting member of the present application is preferably above 90%. Since the liquid-absorbing fiber cotton layer 3 is made of the solid structural fiber 30 with the above-mentioned cross-section having an outwardly protruding portion, it itself has better wettability and stronger adsorption capacity for the atomized matrix. Combined with the optimized selection of the porosity of the liquid-absorbing fiber cotton layer 3 of the present application, the wettability of the liquid-absorbing fiber cotton layer 3 can be further improved, thereby bringing about a better liquid absorption effect.

[0090] In some embodiments, the liquid-conducting component of the present application is an integrated structure formed by stacking a heat-resistant fiber cotton layer 1, a liquid-conducting fiber cotton layer 2, and a liquid-absorbent fiber cotton layer 3 in sequence, or a split structure formed by stacking a heat-resistant fiber cotton layer 1, a liquid-conducting fiber cotton layer 2, and a liquid-absorbent fiber cotton layer 3 in sequence.

[0091] The integrated structure of the liquid guide is not only easy to process into various shapes to adapt to the atomizer cores of different structures of the atomizer device, but also can reduce the risk of the liquid guide falling off between layers during installation, transportation, and use, thereby improving the production yield and working stability of the atomizer core of the atomizer device. In addition, the integrated structure of the liquid guide is easy to control the consistency of product thickness and gram weight, reducing the risk of core sticking caused by uneven thickness of the liquid guide, which is conducive to extending the service life of the liquid guide.

[0092] The liquid-conducting component with a split structure can achieve various changes in the overlapping methods between layers. On the one hand, according to the structural characteristics of the atomizer core, the overall thickness of the liquid-conducting component can be adjusted by adding or reducing the heat-resistant fiber cotton layer 1 or the liquid-conducting fiber cotton layer 2 or the liquid-absorbing fiber cotton layer 3, thereby improving the adaptability of the liquid-conducting component to different atomizer cores. On the other hand, through multiple overlapping methods of different types of fiber cotton layers between the multiple layers of heat-resistant fiber cotton layers 1, the multiple layers of liquid-conducting fiber cotton layers 2 and the multiple layers of liquid-absorbing fiber cotton layers 3, the overall heat resistance, wettability, liquid storage performance, liquid conduction performance, liquid absorption performance and mechanical strength of the liquid-conducting component can be adjusted, thereby achieving variable adjustment of the characteristics of the liquid-conducting component to adapt to the atomization usage requirements of different atomization devices.

[0093] In some embodiments, the total stacking thickness of the heat-resistant fiber cotton layer 1 accounts for 15% to 25% of the overall thickness of the liquid-conducting part of the present application, the total stacking thickness of the liquid-conducting fiber cotton layer 2 accounts for 45% to 70% of the overall thickness of the liquid-conducting part of the present application, and the total stacking thickness of the liquid-absorbent fiber cotton layer 3 accounts for 15% to 30% of the overall thickness of the liquid-conducting part of the present application. The "total stacking thickness" mentioned in the present application refers to the overall thickness of the same type of fiber cotton layers in the liquid-conducting part after they are stacked in sequence, for example: the total stacking thickness of the heat-resistant fiber cotton layer 1 refers to the overall thickness of all the heat-resistant fiber cotton layers 1 in the liquid-conducting part after they are stacked in sequence; the total stacking thickness of the liquid-conducting fiber cotton layer 2 refers to the overall thickness of all the liquid-conducting fiber cotton layers 2 in the liquid-conducting part after they are stacked in sequence; the total stacking thickness of the liquid-absorbent fiber cotton layer 3 refers to the overall thickness of all the liquid-absorbent fiber cotton layers 3 in the liquid-conducting part after they are stacked in sequence.

[0094] The liquid-conducting component of the present application optimizes and adjusts the thickness of the high-temperature resistant part composed of the heat-resistant fiber cotton layer 1, the middle part composed of the liquid-conducting fiber cotton layer 2, and the liquid-absorbing part composed of the liquid-absorbing fiber cotton layer 3, so that the thickness of each part of the liquid-conducting component is reasonably distributed within the allowable range of the overall thickness of the design. On the premise of meeting the high-temperature resistance requirements of the liquid-conducting component, the overall liquid storage, liquid conduction and liquid absorption performance of the liquid-conducting component is improved to the greatest extent, so that the liquid-conducting component of the present application has excellent liquid conduction performance, thereby bringing about a better atomization effect.

[0095] The liquid guide member provided in the present application can be configured as a block structure or a plate structure, or can be rolled into a columnar structure or a tubular structure, etc. The present application does not limit this, and it only needs to meet the structural and usage requirements of different atomizer cores.

[0096] In some embodiments, the present application also provides an electronic atomization device (not shown), the electronic atomization device includes a shell and an atomization core, the shell is provided with a liquid storage tank for storing the atomization matrix and an air flow channel for discharging the atomized gas, wherein the atomization core is arranged in the shell and is connected to the liquid storage tank. The atomization core includes a liquid guide member of any one of the above contents of the present application, and a heating element, and the heating element is attached to the side of the liquid guide member having a heat-resistant fiber cotton layer. When in use, the liquid guide member introduces the atomization matrix into the atomization core, so that the heating element of the atomization core heats and atomizes the atomization matrix to obtain atomized gas, and the atomized gas is finally discharged through the air flow channel for the user to inhale.

[0097] The overall shape of the liquid-conducting component of the present application can be designed according to the actual structure of the atomization core. For example, the liquid-conducting component can be set to a block structure or a plate structure, or it can be rolled into a columnar structure or a tubular structure, and the side with the heat-resistant fiber cotton layer 1 contacts the heating element, and the side with the liquid-absorbing fiber cotton layer 3 contacts the liquid outlet of the liquid storage tank, so that the atomizing matrix in the liquid storage tank of the electronic atomization device of the present application can be directly adsorbed by the liquid-absorbing part formed by the liquid-absorbing fiber cotton layer 3 and transferred to the liquid-conducting fiber cotton layer 2 in the middle part, and then transferred to the heat-resistant fiber cotton layer 1 in the high-temperature resistant part through the liquid-conducting fiber cotton layer 2, and finally the atomizing matrix is ​​heated by the heating element on the side of the liquid-conducting component with the heat-resistant fiber cotton layer 1 and atomized, and the gas generated by the atomization is discharged through the air flow channel together with the intake air flow and sent to the user's mouth for inhalation.

[0098] After adopting the above technical solution, the atomization device of the present application can bring better atomization and smoking effect, significantly improve the smoking taste, and enhance the user experience.

[0099] The above specific examples are used to illustrate the technical solution of this application, which is only used to help understand the content of this application and is not intended to limit this application. For technicians in the technical field to which this application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of this application.
