[0001] Related applications

[0002] This application claims priority to Chinese patent application number 202311422022.2, filed on October 27, 2023, entitled “Liquid-conducting mechanism and its processing device and processing method,” the full text of which is hereby incorporated by reference. Technical Field

[0003] The present application relates to the technical field of atomization equipment, and in particular to a liquid guiding mechanism and a processing device and method thereof. Background Art

[0004] A nebulizer is primarily used to atomize liquids. It consists of a liquid storage mechanism, an atomizing mechanism, and a liquid guide. The liquid guide is located between the liquid storage and atomizing mechanisms to separate the chambers of the two mechanisms. After absorbing liquid from the liquid storage mechanism, the liquid guide needs to maintain the liquid adsorption state to prevent leakage and quickly supply the stored liquid to the atomizing mechanism.

[0005] However, to enhance liquid retention, high-density designs are often required for liquid guides. Too high a density can hinder liquid flow and affect atomization; too low a density can reduce liquid absorption and retention, leading to the risk of leakage. Furthermore, the larger the cross-sectional area of ​​the liquid guide, the higher the requirements for liquid guidance and retention, making it difficult to strike a balance between liquid retention and guidance.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0062] Referring to Figures 1-2, embodiments of the present application provide a liquid guide mechanism, including a liquid guide body 1 having an inner cavity 13. The liquid guide body 1 is provided with a first position 11 and a second position 12. The first position 11 is used to connect to a liquid storage mechanism, and the second position 12 is used to connect to an atomization mechanism. The density of the liquid guide body 1 gradually increases from the first position 11 to the second position 12 to form a gradual liquid aspiration channel, so that the liquid in the liquid guide body 1 can form a flow trend along the liquid aspiration channel. The overall density variation range of the liquid guide body 1 can be determined by the mass and volume of the liquid guide body 1.

[0063] In this configuration, the first position 11 and the second position 12 can be, but are not limited to, located on the inner and outer sides of the liquid-guiding body 1 or at different positions on the liquid-guiding body 1. When the first position 11 and the second position 12 are located on the inner and outer sides of the liquid-guiding body 1, the density of the liquid-guiding body 1 can gradually increase from the outside to the inside, or the density of the liquid-guiding body 1 can also gradually increase from the inside to the outside. From the first position 11 to the second position 12, the density of the liquid guiding body 1 gradually increases, and the capillary effect gradually increases. The liquid in the liquid guiding body 1 forms a flow trend from the first position 11 to the second position 12, that is, a gradual liquid suction channel. The liquid in the liquid storage mechanism gradually flows from the first position 11 to the second position 12 along the gradual liquid suction channel to supply the atomization mechanism for atomization operation. The liquid guiding speed of the liquid guiding body 1 is significantly improved, and the density at the second position 12 of the liquid guiding body 1 is higher, which can well absorb and lock the liquid, reduce the leakage of liquid to the atomization mechanism, thereby better balancing the locking and guiding effects, and can adapt to the installation of the liquid storage mechanism and the atomization mechanism at different positions on the liquid guiding body, which is more flexible to use and solves the problem of the difficult balance between the guiding and locking effects of the liquid guiding part.

[0064] Referring to FIG1 , FIG1 shows a schematic cross-sectional view of a liquid guiding mechanism. Exemplarily, the first position 11 is located outside the liquid guiding body 1, and the second position 12 is located in the inner cavity 13 of the liquid guiding body 1, that is, the liquid storage mechanism can be connected to the outside of the liquid guiding body 1, and the atomizing mechanism can be connected to the inner cavity 13 of the liquid guiding body 1. In this arrangement, the density of the liquid guiding body 1 gradually increases from the outside to the inside, and the capillary effect gradually increases, so that the liquid in the liquid guiding body 1 forms a flow trend from the outside to the inside. The liquid in the liquid storage mechanism gradually flows from the outside of the liquid guiding body 1 to its inner cavity 13 along the gradual liquid suction channel, supplying the atomizing mechanism for atomization operation. The liquid guiding speed of the liquid guiding body 1 is significantly improved, and the density inside the liquid guiding body 1 is higher, which can effectively absorb and lock the liquid, reducing the situation where the liquid leaks to the atomizing mechanism, thereby better balancing the liquid locking and liquid guiding effects, and can also adapt to the needs of a larger cross-sectional area of ​​the liquid guiding member.

[0065] Refer to Figure 2, which shows a cross-sectional schematic diagram of another liquid guiding mechanism. Exemplarily, the first position 11 is located in the inner cavity 13 of the liquid guiding body 1, and the second position 12 is located on the outside of the liquid guiding body 1, that is, the liquid storage mechanism can be connected to the inner cavity 13 of the liquid guiding body 1, and the atomization mechanism can be connected to the outside of the liquid guiding body 1. In this arrangement, the density of the liquid guiding body 1 gradually increases from the inside to the outside, and the capillary effect gradually increases, so that the liquid in the liquid guiding body 1 forms a flow trend from the inside to the outside. The liquid in the liquid storage mechanism gradually flows from the inner cavity 13 of the liquid guiding body 1 to the outside along the gradual liquid suction channel to supply the atomization mechanism for atomization operation. The liquid guiding speed of the liquid guiding body 1 is significantly improved, and the density of the outer side of the liquid guiding body 1 is higher, which can well absorb and lock the liquid, reduce the situation where the liquid leaks to the atomization mechanism, and thus better balance the liquid locking and liquid guiding effects. At the same time, the outer wall area of ​​the liquid-conducting body 1 is much larger than the inner wall area of ​​the liquid-conducting body 1, and the liquid storage capacity on the outer side of the liquid-conducting body 1 can be much larger than the liquid storage capacity on the inner side. The atomization mechanism interacts with the outer wall of the liquid-conducting body 1 with a larger area. When other conditions such as the heating temperature are constant, the atomization effect can be enhanced and the flow rate of the atomized gas can be increased.

[0066] Referring to Figures 1-2, in one embodiment, the liquid-conducting body 1 has a liquid-conducting direction, which points from the first position 11 to the second position 12, that is, the liquid in the liquid-conducting body 1 flows from the first position 11 to the second position 12. The liquid-conducting body 1 includes at least two liquid-conducting layers 14, which are stacked along the liquid-conducting direction to form a density gradient, allowing the liquid to penetrate layer by layer. Of the two adjacent liquid-conducting layers 14, the density of the liquid-conducting layer 14 closer to the first position 11 is lower than the density of the liquid-conducting layer 14 farther from the first position 11. In this manner, the liquid-conducting body 1 is designed in this embodiment as a stacked multi-layered stepped structure, which enables the liquid to flow layer by layer from the first position 11 of the liquid-conducting body 1 to the second position 12, thereby achieving both rapid liquid-conducting operation and facilitating processing of the liquid-conducting body 1.

[0067] For example, the thickness of each liquid-conducting layer 14 can be equal, or the thickness of each liquid-conducting layer 14 can gradually increase along the liquid-conducting direction to enhance the capillary effect and improve liquid absorption and liquid-conducting performance. Two, three, or four liquid-conducting layers 14 can be optionally provided, and the design can be selected based on usage requirements. Liquids suitable for the liquid-conducting body 1 include, but are not limited to, oil or water.

[0068] Referring to FIG. 1 , the liquid-conducting body 1 may include four liquid-conducting layers 14, which are stacked from outside to inside and are designated as liquid-conducting layer 14a, liquid-conducting layer 14b, liquid-conducting layer 14c, and liquid-conducting layer 14d, respectively. The density of liquid-conducting layer 14a is designated as ρ1, the density of liquid-conducting layer 14b is designated as ρ2, the density of liquid-conducting layer 14c is designated as ρ3, and the density of liquid-conducting layer 14d is designated as ρ4. When the first position 11 is located outside the liquid-conducting body 1 and the second position 12 is located within the inner cavity 13 of the liquid-conducting body 1, ρ1 < ρ2 < ρ3 < ρ4. When the first position 11 is located within the inner cavity 13 of the liquid-conducting body 1 and the second position 12 is located outside the liquid-conducting body 1, ρ1 > ρ2 > ρ3 > ρ4.

[0069] In one embodiment, the liquid-conducting body 1 is configured as a cylinder, with an inner cavity 13 arranged axially along the liquid-conducting body 1 to ensure more uniform liquid conduction within and outside the liquid-conducting body 1. A liquid-conducting layer 14 is arranged circumferentially along the inner cavity 13. The inner cavity 13 can be a cylindrical chamber, and the cross-sectional profile of the inner cavity 13 can be similar to the cross-sectional profile of the outer surface of the liquid-conducting body 1. The inner cavity 13 can extend through both ends of the liquid-conducting body 1 to facilitate the installation of a liquid storage mechanism or atomization mechanism, and also to facilitate ventilation or liquid flow.

[0070] Among them, the cross-section of the liquid-conducting body 1 can be but not limited to a circle or a polygon, and the polygon can be but not limited to a square, a rectangle or a hexagon. Of course, the liquid-conducting body 1 can also be provided with a raised portion and / or a recessed portion, and the raised portion and the recessed portion are both arranged along the axial direction of the liquid-conducting body 1.

[0071] Referring to Figure 3, in one embodiment, the liquid-conducting body 1 can be made by connecting multiple composite fibers 15. The fiber structure of the composite fiber 15 includes a skin-core composite structure, a half-wrapped composite structure or an island-type composite structure, which has three-dimensional curling, high fluffiness and covering properties, and has a good adsorption effect on liquids.

[0072] In one embodiment, the composite fiber 15 includes a first fiber filament and a second fiber filament, the first fiber filament and the second fiber filament are connected to each other, and the temperature difference between the melting points of the materials of the first fiber filament and the second fiber filament is in the range of 30°C-90°C, so as to facilitate the molding and processing of the liquid-conducting body 1. It should be specifically explained here that if the temperature difference between the melting points of the materials of the first fiber filament and the second fiber filament is too large, it will be difficult to process the super-long fiber filaments required for the production of the first fiber filament and the second fiber filament when the curling is added. The processing temperature is low and the curling is not obvious. The high temperature will cause the low-melting-point fiber to partially melt, which is very easy to stick to the equipment and cause defective products. If the temperature difference between the melting points of the materials of the first fiber filament and the second fiber filament is small, although the fiber filaments are easier to process, when multiple groups of the first fiber filament and the second fiber filament are extruded to form the liquid-conducting body 1, the process temperature processing range is small. When a certain temperature is reached, the materials of the first fiber filament and the second fiber filament are melted or softened and cannot be molded into parts, and defective products are also likely to appear.

[0073] In one embodiment, the material volume ratio of the first fiber filament to the second fiber filament is in the range of 5:5-8:2. Specifically, the melting point of the material of the first fiber filament may be greater than the melting point of the material of the second fiber filament. The first fiber filament with a high melting point can play a supporting role, and the second fiber filament with a low melting point can contact and bond with adjacent fibers to play a connecting role. The volume ratio of the first fiber filament to the second fiber filament is 5:5-8:2, that is, 1:1-4:1. The volume of the first fiber filament with a high melting point is equal to or greater than the volume of the second fiber filament with a low melting point, and has good strength, so that the liquid-conducting body 1 has good liquid absorption and is not easy to deform.

[0074] In one embodiment, the fiber diameters of the first fiber filament and the second fiber filament are 10 microns to 100 microns, and the liquid-conducting body 1 is a porous structure. When the mass is the same, that is, the volume and density are the same, the interior of the liquid-conducting body 1 is a microscopic space structure in which solid fibers and air are interlaced. When the density remains unchanged, the fiber diameter can determine the number and size of the internal pores of the liquid-conducting body 1. Designing the fiber diameters of the first fiber filament and the second fiber filament to be 10 microns to 100 microns can enable the liquid-conducting body 1 to have a better pore morphology, so that the liquid-conducting body 1 has a better liquid absorption effect.

[0075] In one embodiment, the porosity of the liquid-conducting body 1 is in the range of 80%-99%, so that the liquid-conducting body 1 has a better liquid-conducting rate and oil-locking property. Specifically, the liquid-conducting body 1 can be combined with different porosities of a certain volume of liquid-conducting body 1 by matching the fiber diameter and fiber number of the composite fiber 15 structure. For example, for a liquid-conducting body 1 with a volume of 10 cubic centimeters, the fiber diameter of the composite fiber 15 structure can be designed to be 20 microns, and the fiber number can be designed to be 0.075 grams per cubic centimeter. According to the weight and volume of the composite fiber 15 structure, the porosity of the liquid-conducting body 1 can be determined to be approximately 93%. Among them, the liquid-conducting body 1 can be configured as oil-storage cotton, and the volume range of the liquid-conducting body 1 can be selected from 0.2 cubic centimeters to 20 cubic centimeters. According to the required liquid-conducting and liquid-storing effects, the density range of the liquid-conducting body 1 can be selected from 0.04 grams per cubic centimeter to 0.2 grams per cubic centimeter.

[0076] In one embodiment, the material of the first fiber filament includes one or more of polypropylene, polyethylene, polyethylene terephthalate, polyamide and polylactic acid; the material of the second fiber filament includes one or more of polypropylene, polyethylene, polyethylene terephthalate, polyamide and polylactic acid. The materials of the first fiber filament and the second fiber filament are different so that the first fiber filament and the second fiber filament form a different melting point temperature difference, and the material is easy to process.

[0077] Referring to Figures 3-4, an embodiment of the second aspect of the present application provides a processing device for a liquid-conducting mechanism, which is used to process the aforementioned liquid-conducting mechanism. The liquid-conducting mechanism includes a liquid-conducting body 1, which includes at least two stacked liquid-conducting layers 14. Of the two adjacent liquid-conducting layers 14, the density of the liquid-conducting layer 14 closer to the first position 11 is lower than the density of the liquid-conducting layer 14 farther from the first position 11. The processing device for the liquid-conducting mechanism includes a tube body 2 and at least two delivery channels 21. The delivery channels 21 are disposed within the tube body 2 and are arranged axially along the tube body 2 to facilitate the axial delivery of raw materials for the liquid-conducting layers 14. The delivery channels 21 are provided to correspond to the number of liquid-conducting layers 14, and each delivery channel 21 is used to transport raw materials of different densities corresponding to different liquid-conducting layers 14.

[0078] With this arrangement, when the liquid-guiding mechanism needs to be processed, raw materials of different densities can be placed in each delivery channel 21 according to the design density of the liquid-guiding layer 14. The raw materials in each delivery channel 21 will form a liquid-guiding layer 14 of the corresponding density after processing. In this embodiment, by providing multiple delivery channels 21 to perform layered processing on the liquid-guiding body 1, the stratification between the liquid-guiding layers 14 can be more clearly defined, the density of each liquid-guiding layer 14 is more uniform, and the liquid-guiding and liquid-locking effects of the processed liquid-guiding body 1 are more accurate and balanced.

[0079] Among them, the number of delivery channels 21 and the number of liquid-conducting layers 14 can correspond one to one, or at least two liquid-conducting layers 14 can correspond to one delivery channel 21. For example, when the liquid-conducting body 1 includes four liquid-conducting layers 14, two delivery channels 21 can be provided, and one delivery channel 21 can correspond to every two liquid-conducting layers 14, or four delivery channels 21 can be provided, and each liquid-conducting layer 14 corresponds to a delivery channel 21.

[0080] Referring to Figures 3-4 , in one embodiment, the processing apparatus for a liquid-conducting mechanism further includes a heating mechanism 3 for heating the liquid-conducting body 1 to expand and bond the raw materials within the liquid-conducting body 1. The heating mechanism 3 is connected to the tube 2, meaning that the heating mechanism 3 can be supported by the tube 2. The heating mechanism 3 is positioned at a first location 11 of the liquid-conducting body 1, such that the heating mechanism 3 is close to a location of the liquid-conducting body 1 with a lower density. This creates a temperature difference between the first location 11 and the second location 12 of the liquid-conducting body 1. The liquid-conducting body 1 at the first location 11 expands first, while the liquid-conducting body 1 at the second location 12 expands later. This results in a variable density gradient in each liquid-conducting layer 14 from the first location 11 to the second location 12. The temperature of the heating mechanism 3 gradually increases along the direction in which the raw materials in the liquid-conducting layer 14 are conveyed. Specifically, the conveying channel 21 can have an input port and an output port, which can be located at either end of the tube 2. The direction in which the raw materials in the liquid-conducting layer 14 are conveyed can be from the input port to the output port. In this embodiment, by gradually heating the raw material of the liquid-conducting layer 14, the raw material of the liquid-conducting layer 14 can be gradually expanded and curled and then gradually bonded together, so that the density of each liquid-conducting layer 14 can be more uniform, so that the liquid-conducting and liquid-locking operations of the processed liquid-conducting body 1 can be more accurate.

[0081] For example, the heating mechanism 3 can be, but is not limited to, a heating tube or a heating plate. The heating mechanism 3 can include multiple heating segments, each of which can be arranged along the circumference of the tube body 2. The multiple heating segments can be distributed along the axial direction of the tube body 2. Specifically, the heating mechanism 3 can include at least a first heating segment 31 and a second heating segment 32. The first heating segment 31 can be used to heat the raw material of the liquid-conducting layer 14 for pre-expansion and curling, and the second heating segment 32 can be used to heat and bond the raw material of the liquid-conducting layer 14.

[0082] 1 and 4 , in one embodiment, at least two tube bodies 2 are provided, and the at least two tube bodies 2 are nested with each other. In the at least two nested tube bodies 2, a spacing is provided between two adjacent tube bodies 2 to form a delivery channel 21, so that the delivery channel 21 corresponds to the contour of the liquid-conducting layer 14, so that the positions of the liquid-conducting layers 14 after processing are more corresponding to each other.

[0083] For example, the tubes 2 can be coaxially arranged to make the thickness of each liquid-conducting layer 14 more uniform. The inner and outer circumferential contours of the delivery channel 21 are the same as the inner and outer circumferential contours of the liquid-conducting layer 14. The circumferential contour of the delivery channel 21 can be, but is not limited to, circular or polygonal.

[0084] Referring to Figures 3-4 , in one embodiment, the processing apparatus for the liquid-conducting mechanism further includes a partition 22, which is positioned axially along the tube 2 to align with the conveying direction of the liquid-conducting layer 14 and reduce positional interference between the two. The partition 22 is connected between two adjacent tubes 2, with the two sides of the partition 22 respectively connected to the sidewalls of the two adjacent tubes 2 to separate the conveying channel 21 between the two adjacent tubes 2. At least two partitions 22 are provided along the circumference of the tube 2, forming at least two conveying partitions 211 in the conveying channel 21, facilitating variable density design for parts with complex cross-sections.

[0085] Exemplarily, each liquid-conducting layer 14 can also be divided into at least two liquid-conducting strips, and the conveying partitions 211 are set in a one-to-one correspondence with the liquid-conducting strips. Each conveying partition 211 can be used to convey the raw materials of the corresponding liquid-conducting strip, so that the multiple liquid-conducting strips of the liquid-conducting layer 14 can be heated and processed separately in the corresponding conveying partitions 211. The large heating area and uniform heating make it easier for the liquid-conducting layer 14 to expand and bond to the corresponding density, making the density processing of the liquid-conducting layer 14 more accurate. In addition, the raw materials of each liquid-conducting layer 14 are diverted by multiple conveying partitions 211, reducing the situation where a large amount of raw materials enter the conveying channel 21 at the same time, which is easy to cause blockage. Referring to Figure 5, a plurality of connection points are provided on the tube body 2, and the connection points can be used to connect the partition 22 to the tube body 2.

[0086] Referring to Figures 2-3, in one embodiment, the processing device of the liquid-conducting mechanism may further include a pressing mold 4, which can be connected to the discharge port of the tube body 2 to press and mold the expanded material formed by heating, expanding and bonding the raw materials of the liquid-conducting layer 14, thereby forming a finished part.

[0087] 1-4 and 6 , an embodiment of the third aspect of the present application provides a method for processing a liquid guiding mechanism. Based on the above-mentioned processing device for the liquid guiding mechanism, the method for processing the liquid guiding mechanism includes:

[0088] The layer density of each liquid-conducting layer 14 is obtained, that is, according to the liquid-conducting and liquid-locking requirements of the liquid-conducting body 1, the liquid-conducting and liquid-locking requirements of each liquid-conducting layer 14 can be allocated, and the layer density corresponding to each liquid-conducting layer 14 can be matched. Each liquid-conducting layer 14 can be combined after single-layer processing, or can be processed uniformly in multiple layers.

[0089] According to the layer density of each liquid-conducting layer 14, the raw materials of the liquid-conducting layer 14 are distributed to the corresponding delivery channels 21 to perform layer division of the liquid-conducting body 1. That is, by placing different amounts of raw materials of the liquid-conducting layer 14 into each delivery channel 21, the raw materials of the liquid-conducting layer 14 are expanded and bonded to form liquid-conducting layers 14 of corresponding density, so that the layer density of the liquid-conducting layer 14 is more controllable.

[0090] The raw materials of the liquid conducting layer 14 are heated, and the raw materials of the liquid conducting layer 14 are expanded and bonded to each other by heating and increasing the temperature.

[0091] In this arrangement, by distributing different quantities of raw materials of the liquid-conducting layer 14 in multiple conveying channels 21 and performing heat processing to form liquid-conducting layers 14 with corresponding layer densities, the liquid-conducting layers 14 with different layer densities are stacked and combined with each other to form a liquid-conducting body 1 with variable density. The processing is convenient, and the layer density in each liquid-conducting layer 14 can form a corresponding required density, so that the density change of the liquid-conducting body 1 is more regular. The processed liquid-conducting body 1 can better achieve the required liquid-conducting and liquid-locking effects, which is convenient for balancing the liquid-conducting and liquid-locking effects of the liquid-conducting body 1.

[0092] In one embodiment, obtaining the layer density of the liquid conducting layer 14 includes:

[0093] The overall density variation range of the liquid guiding body 1 is obtained, and the threshold value of the overall density variation range required by the liquid guiding body 1 can be determined first according to the liquid guiding and liquid locking requirements of the liquid guiding body 1 .

[0094] The layer density of each liquid-conducting layer 14 is determined according to the overall density variation range. That is, according to the threshold of the overall density variation range required by the liquid-conducting body 1, the threshold of the overall density variation range can be numerically divided from high to low to form segmented thresholds. The number of segmented thresholds corresponds to the number of liquid-conducting layers 14 one by one. The layer density of each liquid-conducting layer 14 is selected within the corresponding segmented threshold so that the combination of the processed liquid-conducting layers 14 can meet the liquid-conducting and liquid-locking requirements of the liquid-conducting body 1.

[0095] In one embodiment, the layered division of the liquid-conducting body 1 includes:

[0096] The raw material of the liquid conducting layer 14 is fiber filaments, which can be configured as the composite fibers 15 mentioned above, or as a fiber structure composed of multiple single-material fibers, as long as the production requirements of the liquid conducting layer 14 are met.

[0097] The number of fiber filaments in each delivery channel 21 is determined based on the layer density of the liquid-conducting layer 14. Specifically, the layer density of the liquid-conducting layer 14 can be directly selected as needed, or calculated based on the required volume and mass of the liquid-conducting layer 14. The number of fiber filaments is denoted as N, the linear weight of a single fiber filament is denoted as m, the corresponding shrinkage ratio of the fiber filament is denoted as η, and the layer density of the liquid-conducting layer 14 is denoted as ρ. The formula for calculating the number of fiber filaments N can be:

[0098] N=ρ / m×η

[0099] By using the above formula, the number of fiber filaments corresponding to the liquid-conducting layer 14 can be obtained, and then the fiber filaments can be distributed to each delivery channel 21. For example, the fiber filaments can be equally divided into each delivery channel 21, or the difference in the number of fiber filaments in each delivery channel 21 needs to be within a preset range, so that the layer density of the liquid-conducting layer 14 can meet the usage requirements.

[0100] In one embodiment, heating the raw material of the liquid conducting layer 14 includes:

[0101] The raw material of the liquid-conducting layer 14 is heated in sections along its own conveying path. The heating temperature of the raw material of the liquid-conducting layer 14 gradually increases along the conveying direction. That is, different temperature zones can be formed on the conveying path of the raw material of the liquid-conducting layer 14. The liquid-conducting layer 14 is long, and the multiple temperature zones can make the heating of the liquid-conducting layer 14 more uniform, and can also make the liquid-conducting layer 14 expand and bond in sections.

[0102] Exemplarily, the heating position can be located at the first position 11 of the liquid-conducting body 1, that is, the heating position can be close to the liquid-conducting layer 14 with a lower layer density, so that a temperature difference is formed between the liquid-conducting layers 14. The temperature of the liquid-conducting layer 14 with a lower layer density close to the heating position is higher, and the raw material will expand first to form a larger expansion gap. The temperature of the liquid-conducting layer 14 with a higher layer density away from the heating position is lower, and the raw material will expand later to form a smaller expansion gap, so that each liquid-conducting layer 14 can also form a density gradient changing from the first position 11 to the second position 12.

[0103] In one embodiment, heating the raw material of the liquid conducting layer 14 in sections along its conveying path includes:

[0104] The feed path for the liquid-conducting layer 14 is divided into a first heating section and a second heating section. The heating temperature in the first heating section ranges from 60°C to 160°C, adapting to the characteristics of the fiber material and facilitating pre-expansion and curling of the fibers. The heating temperature in the second heating section ranges from 120°C to 220°C, adapting to the characteristics of the fiber material and facilitating vitrification and bonding of the low-melting-point portion of the fiber.

[0105] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
