[0021] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0022] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0023] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0024] This application discloses a liquid guiding component 100, which is used in an atomizing device. The liquid guiding component 100 has a multi-layer composite structure. A solid aerosol matrix 211 is added to the middle layer of the liquid guiding component 100 so that during the use of the atomizing device, the solid aerosol matrix 211 in the liquid guiding component 100 is heated to restore the original taste of the solid aerosol matrix and improve the taste of the atomizing device.

[0025] Please refer to the liquid guiding component 100 in this embodiment of the application. Figure 1 , Figure 2 and Figure 3 The liquid guiding component 100 includes an atomizing part 1, a conductive medium 2, and a liquid guiding part 3 arranged sequentially along its thickness direction. The atomizing part 1 includes a first fiber layer 11, which includes a mesh structure formed by interlacing first fibers. The conductive medium 2 includes a mixing layer 21, which includes a mesh structure formed by interlacing second fibers and a solid aerosol matrix 211. The liquid guiding part 3 includes a second fiber layer 31, which includes a mesh structure formed by interlacing third fibers. The conductive medium 2 is sandwiched and composited between the atomizing part 1 and the conductive part 3 in the thickness direction of the liquid guiding component 100. In this way, the outer mesh structure formed by the interlacing of the first fiber and the second fiber respectively wraps the middle mesh structure formed by the interlacing of the second fiber and the solid aerosol matrix 211, thereby reducing the probability of the solid aerosol matrix 211 falling off in the intermediate conductive medium 2. Furthermore, in the liquid guiding component 100 of this application, the solid aerosol matrix 211 is added to the mesh structure of the mixing layer 21 in the conductive medium 2. During the use of the liquid guiding component 100 in the atomizing device, the solid aerosol matrix 211 in the liquid guiding component 100 is heated to generate aerosol. After mixing with the aerosol generated by the heating of the atomizing liquid, it helps to restore the taste of the solid aerosol matrix itself and can improve the taste of the atomizing device.

[0026] In some embodiments, the first fiber in the atomizing section 1, the second fiber in the conductive medium 2, and the third fiber in the liquid guiding section 3 can all be natural fibers or chemical fibers, or they can be mixed fibers of natural and chemical fibers, such as one or more of cotton fibers, hemp fibers, wood pulp fibers, viscose fibers, cupro fibers, lyocell fibers, and Wyleffer fibers. Of course, in other embodiments, the first, second, and third fibers can also be mixed with other high-performance fibers and characteristic fibers to improve the liquid conductivity and high-temperature resistance of the processed atomizing section 1, conductive medium 2, and liquid guiding section 3.

[0027] In some embodiments, the solid aerosol matrix 211 in the mixing layer 21 of the conductive medium 2 can be selected according to the application scenario. For example, in the field of electronic cigarettes, the solid aerosol matrix 211 can be made of tobacco, mint or other flavorings that can improve the flavor of aerosols, or a mixture of tobacco and flavorings can also be used; in the medical field, the solid aerosol matrix 211 can be made of medicinal materials such as honeysuckle and isatis root.

[0028] For the mesh structures in the first fiber layer 11 of the atomizing section 1 and the second fiber layer 31 of the liquid guiding section 3, the first fiber and the third fiber can be uniformly spread on the mesh curtain by airflow to form corresponding mesh structures, or they can be oriented by combing and then formed by laying the mesh. For the mesh structure of the mixing layer 21 in the conductive medium 2, the solid aerosol matrix 211 and the second fiber can also be formed into a mesh by airflow or mechanical combing.

[0029] Before the first and third fibers are interwoven into a network structure, and before the second fiber and the solid aerosol matrix 211 are interwoven into a network structure, the first, second, and third fibers and the solid aerosol matrix 211 need to be pretreated respectively. The pretreatment process for the first, second, and third fibers is the same as the pretreatment process for fiber web formation in the processing of liquid guiding components in the prior art.

[0030] In some embodiments, please refer to Figures 1 to 3 In the mesh structure of the mixing layer 21 in the conductive medium 2, the solid aerosol matrix 211 includes a fibrous matrix, a granular matrix, or a mixed matrix of fibrous matrix and granular matrix. The solid aerosol matrix 211 needs to be dried and screened before forming the mesh. After the cleaned solid aerosol matrix 211 is dried, its moisture content needs to be controlled between 1% and 10%. Then the dried solid aerosol matrix 211 is screened.

[0031] In embodiments where the solid aerosol matrix 211 includes tobacco, the selected fibrous matrix tobacco shreds need to have a length of 1 mm to 5 mm and an aspect ratio greater than 10; in another embodiment, the selected granular matrix tobacco particles need to have an average diameter of 0.2 mm to 1 mm. Alternatively, in other embodiments, the length of the tobacco shreds can be greater than 5 mm or less than 1 mm, the aspect ratio can be less than or equal to 10, and the average diameter of the tobacco particles can be less than 0.2 mm or greater than 1 mm, to ensure that the tobacco shreds and / or tobacco particles do not easily detach from the network structure formed by the interweaving of the tobacco shreds and / or tobacco particles with the second fiber. Other solid aerosol matrices 211 can also adopt the above screening conditions.

[0032] In some embodiments, before the solid aerosol matrix 211 is interwoven with the second fiber to form a web, the solid aerosol matrix 211 needs to undergo an expansion treatment to increase the surface area of ​​the solid aerosol matrix 211, so that the solid aerosol matrix 211 has better adsorption and liquid conductivity, and at the same time, the solid aerosol matrix 211 can release its original flavor more fully during the heating process.

[0033] In some embodiments, the second fiber and the solid aerosol matrix 211 are uniformly mixed in the mixing layer 21, and the mass ratio of the solid aerosol matrix 211 to the entire mixing layer 21 is greater than or equal to 30%, with the maximum mass ratio being sufficient to allow the solid aerosol matrix 211 and the second fiber to be properly laid out. In some embodiments, the mass ratio of the solid aerosol matrix 211 to the mixing layer 21 can reach 60%-75%, provided that the solid aerosol matrix 211 does not fall off from the mixing layer 21.

[0034] In some embodiments, please refer to Figure 3 The conductive medium 2 also includes a third fiber layer 22, which comprises a mesh structure formed by interlacing fourth fibers. The material of the fourth fiber is the same as that of the first, second, and third fibers. The processing steps for the fourth fiber to interlaced into a mesh structure are the same as those for the first fiber layer 11 and the third fiber layer 22 to interlaced into meshes. The mixing layer 21 and the third fiber layer 22 in the conductive medium 2 are stacked in the thickness direction of the liquid guiding component 100 to increase the liquid guiding rate of the conductive medium 2 while reducing the probability of solid aerosol matrix 211 falling off from the mixing layer 21. Furthermore, the number of mixing layers 21 in the conductive medium 2 is greater than the number of third fiber layers 22 to ensure the content of solid aerosol matrix 211 in the conductive matrix.

[0035] In some embodiments, the conductive medium 2 includes only a mixing layer 21, and the mixing layer 21 has multiple layers, which are stacked in the thickness direction of the liquid guiding element 100.

[0036] In some embodiments, after the first fiber layer 11, the mixed layer 21, the second fiber layer 31, and the third fiber layer 22 are interwoven into a web, the first fiber layer 11, the mixed layer 21, the third fiber layer 22, and the second fiber layer 31 are laid into a web and then hydroentangled and shaped to form a stable liquid-conducting component 100. Alternatively, the first fiber layer 11, the multilayer mixed layer 21, and the second fiber layer 31 are laid into a web and then hydroentangled and shaped to form a stable liquid-conducting component 100. In other embodiments, the first fiber layer 11, the mixed layer 21, the third fiber layer 22, and the second fiber layer 31; or the first fiber layer 11, the multilayer mixed layer 21, and the second fiber layer 31 can also be formed into the liquid-conducting component 100 by adhesive bonding.

[0037] In some embodiments, please refer to Figures 1 to 3 The liquid guiding component 100 is formed by a semi-cross-laid mesh method. The laying direction of at least one of the first fiber layer 11 and the second fiber layer 31 is arranged to cross the laying direction of the mixing layer 21, so as to reduce the probability of solid aerosol matrix 211 falling off in the mixing layer 21.

[0038] In one embodiment, the laying directions of the first fiber layer 11 and the second fiber layer 31 may both intersect with the laying direction of the mixed layer 21. During the web laying process, both the first fiber layer 11 and the second fiber layer 31 can be laid in a straight-lay manner, while the mixed layer 21 is laid in an interleaved manner. The laying direction of the first fiber layer 11 is the extension direction of most of the carded first fibers, and the laying direction of the second fiber layer 31 is the extension direction of most of the carded third fibers. Please refer to [reference needed]. Figures 1 to 3 The arrows in the first fiber layer 11 and the second fiber layer 31 indicate the direction of the fiber layer; similarly, the laying direction of the mixed layer 21 is the extension direction of most of the combed second fibers and most of the solid aerosol matrix 211 in the mixed layer 21. Please refer to [reference needed]. Figures 1 to 3 The arrows in the mixed layer 21 indicate the direction. The laying direction of the first fiber layer 11 and the second fiber layer 31 is the same as the moving direction of the mesh curtain. The mixed layer 21 is laid in an interlaced manner to ensure that the laying direction of the mixed layer 21 is intersected with the laying direction of the first fiber layer 11 and the laying direction of the second fiber layer 31.

[0039] Of course, in other embodiments, if the solid aerosol matrix 211 does not fall off from the liquid guide 100, at least one of the first fiber layer 11 and the second fiber layer 31 and the mixing layer 21 can be laid in a straight manner, and the laying direction of at least one of the first fiber layer 11 and the second fiber layer 31 is the same as the laying direction of the mixing layer 21.

[0040] In some embodiments, in order to increase the content of solid aerosol matrix 211 in the liquid guiding component 100 without increasing the probability of solid aerosol matrix 211 falling off from the liquid guiding component 100, the number of mixing layers 21 can be two, three or more, and the structure, composition and mass ratio of solid aerosol matrix 211 to the second fiber of each mixing layer 21 are equal.

[0041] Multiple hybrid layers 21 are sandwiched between the first fiber layer 11 and the second fiber layer 31 in their thickness direction. During the web laying process, both the first fiber layer 11 and the second fiber layer 31 are laid in a straight-lay manner. Please refer to [reference needed]. Figure 1 and Figure 2Each mixing layer 21 is laid in an interleaved manner, with adjacent mixing layers 21 having different laying directions in the thickness direction. For example, during the laying process of different mixing layers 21, the discharge speed of the mixing layers 21 can be changed to make the discharge speed of adjacent mixing layers 21 different, thus achieving different extension directions for most of the second fibers and solid aerosol matrix 211 in adjacent mixing layers 21 on the mesh screen; or, during the laying process of different mixing layers 21, the discharge speed of the mesh screen can be changed to ensure that most of the second fibers and solid aerosol matrix 211 in different mixing layers 21 have different extension directions. This setting of different laying directions for adjacent mixing layers 21 helps reduce the probability of solid aerosol matrix 211 falling off the mixing layer 21.

[0042] In some embodiments, to further reduce the probability of the immobilized aerosol matrix 21 detaching from the liquid guiding component 100 and to increase the liquid guiding rate of the liquid guiding component 100, please refer to... Figure 3 In the conductive medium 2 located between the first fiber layer 11 and the second fiber layer 31, the mixing layer 21 and the third fiber layer 22 are stacked in the thickness direction of the liquid guiding component 100. The mixing layer 21 can be staggered with the third fiber layer 22 or several mixing layers 21 can be located between two adjacent third fiber layers 22, and the number of mixing layers 21 is greater than the number of third fiber layers 22, so as to ensure the content of solid aerosol matrix 211 in the conductive medium 2. The laying direction of the mixing layer 21 is different from that of the adjacent third fiber layer 22. Similarly, the laying direction of the adjacent mixing layer 21 and the adjacent third fiber layer 22 can be different by changing the discharge speed of the mixing layer 21 and the third fiber layer 22 or the discharge speed of the screen.

[0043] In some embodiments, the first fiber layer 11, the second fiber layer 31, and multiple mixed layers 21, or possibly multiple third fiber layers 22, are hydroentangled and then shaped. The hydroentangled liquid guide 100 needs to undergo a high-temperature rolling process. The high-temperature rolling conditions are: a pressing strength range of 5 MPa to 15 MPa and a temperature of 90°C to 110°C. The liquid guide 100 after the high-temperature rolling process also needs to undergo a drying process to ensure the structural stability and liquid absorption performance of the liquid guide 100.

[0044] The present application will be further described in detail below through specific embodiments and comparative examples. The following embodiments and comparative examples are only for further illustration of the present application and should not be construed as limiting the present application. In this embodiment or comparative example, unless otherwise specified, the instruments used are all commercially available, and the experimental operations are all carried out in accordance with the product instructions and conventional test specifications.

[0045] (1) Preparation of the liquid guiding component in the examples and comparative examples:

[0046] Example 1: After washing and drying the tobacco, the water content in the tobacco was controlled to be 8%. Tobacco particles with an average diameter of 0.5 mm were screened out from the tobacco. The above tobacco particles, accounting for 40% by mass, were mixed evenly with Lyocell fiber material and interwoven into a mesh structure to form a mixed layer. This mixed layer was laid out with the first fiber layer and the second fiber layer, which were respectively formed by interweaving Lyocell fiber material, in an interlaced manner. After hydroentangling, it was subjected to high-temperature roll pressing under a pressure of 8 MPa and a temperature of 105°C. After drying, a liquid guiding part was obtained.

[0047] Example 2: After washing and drying the tobacco, the water content in the tobacco was controlled to be 8%. Tobacco shreds with a length of 3mm to 5mm and an aspect ratio of 20 were selected from the tobacco. The above tobacco shreds with a mass ratio of 40% were mixed evenly with Lyocell fiber material and woven into a mesh structure to form a mixed layer. This mixed layer was laid in an interlaced manner with the first fiber layer and the second fiber layer formed by Lyocell fiber material, respectively. After hydroentangling, it was subjected to high-temperature roll pressing under a pressure of 8MPa and a temperature of 105℃. After drying, a liquid guiding part was obtained.

[0048] Example 3: After washing and drying the tobacco, the water content in the tobacco was controlled to be 8%. Tobacco shreds with a length of 3mm to 5mm and an aspect ratio of 20 were selected from the tobacco. The above tobacco shreds with a mass ratio of 60% were mixed evenly with Lyocell fiber material and woven into a mesh structure to form a mixed layer. This mixed layer was laid in an interlaced manner with the first fiber layer and the second fiber layer formed by Lyocell fiber material, respectively. After hydroentangling, it was subjected to high-temperature roll pressing under a pressure of 8MPa and a temperature of 105℃. After drying, a liquid guiding part was obtained.

[0049] Comparative Example 1: Lyocell fiber material is interwoven to form a mesh structure. The three-layer mesh structure is laid out in an interlaced manner and hydroentangled. It is then subjected to high-temperature roll pressing under a pressure of 8MPa and a temperature of 105℃. After drying, a liquid guiding component is obtained. The liquid guiding component is then cut and applied to an atomizing device.

[0050] Comparative Example 2: After cleaning and drying the tobacco, the water content in the tobacco was controlled to be 8%. Tobacco particles with an average diameter of 0.05 mm were screened out from the tobacco. The above tobacco particles, accounting for 40% by mass, were mixed evenly with Lyocell fiber material and interwoven into a mesh structure to form a mixed layer. This mixed layer was laid out with the first fiber layer and the second fiber layer, which were respectively formed by interweaving Lyocell fiber material, in an interlaced manner. After hydroentangling, it was subjected to high-temperature roll pressing under a pressure of 8 MPa and a temperature of 105°C. After drying, a liquid guiding part was obtained.

[0051] Comparative Example 3: After washing and drying the tobacco, the water content in the tobacco was controlled to be 8%. Tobacco particles with an average diameter of 2 mm were screened out from the tobacco. The above tobacco particles, accounting for 40% by mass, were mixed evenly with Lyocell fiber material and interwoven into a mesh structure to form a mixed layer. This mixed layer was laid out with the first fiber layer and the second fiber layer, which were respectively formed by interweaving Lyocell fiber material, in an interlaced manner. After hydroentangling, it was subjected to high-temperature roll pressing under a pressure of 8 MPa and a temperature of 105°C. After drying, the product was obtained as a liquid guide.

[0052] (2) Smoking sensation and spillage test

[0053] The liquid guiding components in Examples 1 to 3 and Comparative Examples 1 to 3 were immersed in a 1:1 mixture of propylene glycol and glycerol and kept at 120°C for 8 hours. The presence of loose tobacco shreds or tobacco particles in the solution was then checked.

[0054] After cutting the above-mentioned liquid guiding component, it was installed into the same atomizing device. The heating wire circuit was set to 1.2Ω. A taste test was conducted, and the score was 1-5 points, with 5 points being the full score. The higher the score, the higher the tobacco intensity and the closer the smoking taste is to the smoking taste produced by directly heating traditional tobacco.

[0055] The test results are shown in the table below:

[0056]

[0057]

[0058] As shown in the table above, the liquid guides in Examples 1 and 2, which have tobacco particles added to the middle layer, have higher inhalation scores compared to the liquid guide in Comparative Example 1, which does not have tobacco particles added, thus resulting in a better taste for the corresponding atomizing devices. Similarly, the liquid guides in Examples 2 and 3, which have tobacco shreds added to the middle mixing layer, have higher inhalation scores compared to the liquid guide in Comparative Example 1, which does not have tobacco shreds added, thus resulting in a better taste for the corresponding atomizing devices.

[0059] The liquid guide in Comparative Example 3 has a lower smoking score compared to the liquid guides in Examples 1 and 2. This is because the excessively large average diameter of the tobacco particles in the liquid guide results in a burnt taste, reducing the overall flavor. In Comparative Example 2, although some tobacco particles are scattered compared to the liquid guides in Examples 1 and 3, this does not affect the smoking experience. This is because a smaller average diameter of the tobacco particles in the liquid guide results in a better smoking experience for the corresponding atomizing device. The liquid guide in Example 2 has a higher smoking score compared to the liquid guide in Example 1. Therefore, a higher tobacco content in the liquid guide results in a better smoking experience for the corresponding atomizing device.

[0060] The embodiments of this application also provide an atomizing device, which includes a heating element (not shown in the figure) and a liquid guiding element 100 as described in any of the above embodiments. The liquid guiding element 100 is installed in the atomizing chamber of the atomizing device, and the heating element is installed on the liquid guiding element 100 and in contact with the atomizing part 1 on the liquid guiding element 100. In the thickness direction of the liquid guiding element 100, the surface in contact with the heating element is the atomizing surface, which is located in the atomizing part 1. The surface opposite to the atomizing surface is the liquid guiding surface, which is located in the liquid guiding part 3. The liquid guiding surface is used to contact the liquid atomizing matrix in the liquid storage chamber of the atomizing device. The atomizing surface and the heating element are located in the atomizing chamber. The liquid guiding surface is used to guide the liquid atomizing matrix in the liquid storage chamber to the atomizing surface. The heating element can heat the liquid atomizing matrix that is guided to the atomizing surface to generate an aerosol.

[0061] In some embodiments, the liquid guiding component 100 is wound around the outer peripheral surface of a generally cylindrical heating element (not shown in the figure). Then, the heating element and the wound liquid guiding component 100 are inserted into an atomizing tube (not shown in the figure). The position of the liquid guiding component 100 is restricted by the annular space between the atomizing tube and the heating element. After absorbing liquid, the liquid guiding component 100 expands and adheres to the inner wall of the atomizing tube and the outer surface of the heating element, which can effectively prevent the liquid guiding component 100 from falling out of the atomizing chamber. The liquid guiding surface is the outer peripheral surface of the liquid guiding component 100, and the atomizing surface is the inner peripheral surface of the liquid guiding component.

[0062] In some embodiments, the liquid guiding component 100 is fixed in the atomizing chamber by a fixing component, such as a fixing frame. The surface of the liquid guiding component 100 that is in fluid communication with the liquid storage chamber in its thickness direction is the liquid guiding surface, and the surface arranged opposite to the liquid guiding surface is the atomizing surface. The heating element is fixed on the atomizing surface.

[0063] In some embodiments, in the liquid guiding component 100, the first fiber in the atomizing section 1 that contacts the heating element is made of natural fiber, such as at least one of cotton fiber, hemp fiber, wood pulp fiber, and ramie fiber; the second and fourth fibers in the conductive medium 2 near the atomizing surface in the thickness direction of the liquid guiding component 100 can also be made of the above-mentioned natural fibers. Because natural fibers have better overall performance in terms of oil absorption, thermal conductivity, and high-temperature resistance than chemical fibers, natural fibers, when formed or located near the atomizing surface, are less prone to deformation or scorching, and do not release harmful substances at high temperatures, thus helping to improve the taste of the atomizing device while extending the service life of the liquid guiding component 100.

[0064] In the thickness direction of the liquid guiding component 100, the third and fourth fibers that are close to or form the liquid guiding surface can be selected as natural fibers or chemical fibers according to different requirements.

[0065] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
