Description

Technical Field

[0001] This application relates to the field of atomizing equipment technology, and in particular to liquid guiding mechanisms and their processing devices and methods. Background Technology

[0002] Atomizers are mainly used to atomize liquids. An atomizer includes a liquid storage mechanism, an atomizing mechanism, and a liquid guide. The liquid guide is located between the liquid storage mechanism and the atomizing mechanism to separate the chambers of the two mechanisms. After the liquid guide draws liquid from the liquid storage mechanism, it needs to maintain the adsorption state of the liquid to prevent leakage and quickly supply the stored liquid to the atomizing mechanism.

[0003] However, to enhance the liquid-locking effect, the liquid guiding component usually needs to adopt a high-density design. If the density is too high, the liquid guiding will not be smooth, affecting the atomization effect; if the density is too low, both the adsorption and liquid-locking capacity will decrease, and there will be a risk of leakage. Moreover, the larger the cross-sectional area of ​​the liquid guiding component, the higher the requirements for liquid guiding and liquid-locking performance will be, and it is difficult to balance the liquid-locking and liquid guiding effects. Summary of the Invention

[0004] Therefore, it is necessary to provide a liquid guiding mechanism and its processing device and processing method to address the problem of the difficulty in balancing the liquid guiding and liquid locking effects of liquid guiding components.

[0005] The liquid guiding mechanism provided in the first aspect of this application includes:

[0018] The processing apparatus for the liquid guiding mechanism provided in the second aspect of this application is used to process the liquid guiding mechanism described above. The liquid guiding body includes at least two stacked liquid guiding layers. In two adjacent liquid guiding layers, the density of the liquid guiding layer closer to the first position is less than the density of the liquid guiding layer farther from the first position.

[0020] In one embodiment, the processing device of the liquid guiding mechanism further includes a heating mechanism for heating the liquid guiding body. The heating mechanism is connected to the tube body and is located at a first position on the liquid guiding body. The temperature of the heating mechanism gradually increases along the conveying direction of the raw material in the liquid guiding layer.

[0021] In one embodiment, at least two tubes are provided, and a gap is provided between adjacent two tubes to form the conveying channel.

[0022] In one embodiment, the processing device of the liquid guiding mechanism further includes a partition plate, which is arranged along the axial direction of the tube body and connected between two adjacent tube bodies. At least two partition plates are arranged along the circumference of the tube body so that the conveying channel forms at least two conveying zones.

[0023] The processing method for the liquid guiding mechanism provided in the third aspect of this application, based on the above-described processing apparatus for the liquid guiding mechanism, includes:

[0024] Obtain the layer density of each liquid-conducting layer;

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0055] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0056] See Figure 1-2 The liquid guiding mechanism provided in the first aspect of this application includes a liquid guiding body 1, which has an inner cavity 13. The liquid guiding 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 atomizing mechanism. The density of the liquid guiding body 1 gradually increases from the first position 11 to the second position 12 to form a gradual liquid absorption channel, so that the liquid in the liquid guiding body 1 can flow along the liquid absorption channel. The overall density variation range of the liquid guiding body 1 can be determined by the mass and volume of the liquid guiding body 1.

[0057] With 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-conducting body 1 or at different positions on the liquid-conducting body 1. When the first position 11 and the second position 12 are located on the inner and outer sides of the liquid-conducting body 1, the density of the liquid-conducting body 1 can gradually increase from the outside to the inside, or the density of the liquid-conducting 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 strengthens. The liquid in the liquid guiding body 1 forms a flow trend from the first position 11 to the second position 12, i.e., a gradual liquid absorption channel. The liquid in the liquid storage mechanism gradually flows from the first position 11 to the second position 12 along the gradual liquid absorption channel, supplying the atomizing mechanism for atomization. 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 effectively adsorb and lock the liquid, reducing the leakage of liquid to the atomizing mechanism. This better balances the liquid locking and liquid guiding effects, and can adapt to different positions of the liquid guiding body for the liquid storage mechanism and the atomizing mechanism, making it more flexible to use and solving the problem of balancing the liquid guiding and liquid locking effects of the liquid guiding component.

[0058] See Figure 1 , Figure 1A cross-sectional schematic diagram of a liquid guiding mechanism is shown. Optionally, the first position 11 is located on the outside of 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 storage mechanism gradually flows from the outside of the liquid guiding body 1 to its inner cavity 13 along the gradual liquid absorption channel, supplying the atomizing mechanism for atomization. The liquid guiding speed of the liquid guiding body 1 is significantly improved, and the density of the inner side of the liquid guiding body 1 is higher, which can effectively adsorb and lock the liquid, reducing the leakage of liquid to the atomizing mechanism, thereby better balancing the liquid locking and liquid guiding effects, and also adapting to the need for a larger cross-sectional area of ​​the liquid guiding component.

[0059] See Figure 2 , Figure 2 A cross-sectional schematic diagram of another liquid guiding mechanism is shown. Optionally, 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 outer side 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 atomizing mechanism can be connected to the outer side 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 storage mechanism flows from the inner cavity 13 of the liquid guiding body 1 to the outside along the gradual liquid absorption channel, supplying the atomizing mechanism for atomization. The liquid guiding speed of the liquid guiding body 1 is significantly improved, and the higher density on the outer side of the liquid guiding body 1 can effectively adsorb and lock the liquid, reducing the leakage of liquid to the atomizing mechanism, thereby better balancing the liquid locking and guiding effects. Meanwhile, the outer wall area of ​​the liquid guiding body 1 is much larger than the inner wall area of ​​the liquid guiding body 1, and the liquid storage capacity on the outer side of the liquid guiding body 1 is much larger than the liquid storage capacity on the inner side. The interaction between the atomizing mechanism and the outer wall of the larger liquid guiding body 1 can enhance the atomization effect and increase the flow rate of the atomizing gas when the heating temperature and other conditions are constant.

[0060] See Figure 1-2In some embodiments, the liquid-conducting body 1 has a liquid-conducting direction, pointing from the first position 11 to the second position 12, meaning that 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 permeate layer by layer. In two adjacent liquid-conducting layers 14, the density of the liquid-conducting layer 14 closer to the first position 11 is less than the density of the liquid-conducting layer 14 farther from the first position 11. With this configuration, this embodiment designs the liquid-conducting body 1 as a multi-layered stepped structure, enabling the liquid to flow layer by layer from the first position 11 to the second position 12, thus achieving rapid liquid-conducting operation and facilitating the processing of the liquid-conducting body 1.

[0061] In this embodiment, the thickness of each liquid-conducting layer 14 can be equal, or the thickness of the liquid-conducting layer 14 can gradually increase along the liquid-conducting direction to enhance the capillary effect and improve the liquid absorption and conduction effect. Two, three, or four liquid-conducting layers 14 can be optionally provided, and the design can be selected according to the application requirements. The liquid suitable for the liquid-conducting body 1 can be, but is not limited to, oil or water.

[0062] See Figure 1 The liquid-conducting body 1 may include four liquid-conducting layers 14, which are stacked from the outside to the inside and are respectively denoted as liquid-conducting layer 14a, liquid-conducting layer 14b, liquid-conducting layer 14c, and liquid-conducting layer 14d. The density of liquid-conducting layer 14a is denoted as ρ1, the density of liquid-conducting layer 14b is denoted as ρ2, the density of liquid-conducting layer 14c is denoted as ρ3, and the density of liquid-conducting layer 14d is denoted as ρ4. When the first position 11 is located on the outside of the liquid-conducting body 1 and the second position 12 is located in the inner cavity 13 of the liquid-conducting body 1, ρ1 < ρ2 < ρ3 < ρ4. When the first position 11 is located in the inner cavity 13 of the liquid-conducting body 1 and the second position 12 is located on the outside of the liquid-conducting body 1, ρ1 > ρ2 > ρ3 > ρ4.

[0063] In some embodiments, the liquid-conducting body 1 is configured as a cylinder, and the inner cavity 13 is arranged along the axial direction of the liquid-conducting body 1 to make the liquid-conducting process inside and outside the liquid-conducting body 1 more uniform. The liquid-conducting layer 14 is arranged circumferentially along the inner cavity 13, and the inner cavity 13 may be a cylindrical chamber, and the cross-sectional profile of the inner cavity 13 may be similar to the cross-sectional profile of the outer side of the liquid-conducting body 1. The inner cavity 13 may extend through both ends of the liquid-conducting body 1 to facilitate the installation of a liquid storage mechanism or an atomizing mechanism, and also to facilitate air or liquid passage.

[0064] The cross-section of the liquid guiding body 1 may be, but is not limited to, circular or polygonal. The polygonal shape may be, but is not limited to, square, rectangular or hexagonal. Of course, the liquid guiding body 1 may also be provided with protrusions and / or recesses, and the protrusions and recesses are provided along the axial direction of the liquid guiding body 1.

[0065] See Figure 3In some embodiments, the liquid-conducting body 1 may be made of multiple composite fibers 15 connected together. The fiber structure of the composite fibers 15 includes a core-sheath composite structure, a semi-enclosed composite structure, or an island-type composite structure, which has three-dimensional curl, high fluffiness and coverage, and has a good adsorption effect on liquids.

[0066] In some embodiments, the composite fiber 15 includes a first fiber filament and a second fiber filament, which are interconnected. The melting point difference between the first and second fiber filaments is 30°C-90°C to facilitate the molding of the liquid-conducting body 1. It should be specifically noted that if the melting point difference between the first and second fiber filaments is too large, the extra-long fiber filaments required for production will be difficult to process with additional crimping. Low processing temperatures result in insignificant crimping, while high temperatures cause the low-melting-point fibers to melt, easily sticking to the equipment and resulting in defective products. If the melting point difference between the first and second fiber filaments is small, although the fiber filaments are easier to process, the processing temperature range is narrow when multiple sets of first and second fiber filaments are extruded to form the liquid-conducting body 1. At a certain temperature, both the first and second fiber filaments melt or soften, making it impossible to mold into parts, also easily resulting in defective products.

[0067] In some embodiments, the 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 first fiber filament can be greater than that of the second fiber filament. The first fiber filament with a high melting point can play a supporting role, while the second fiber filament with a low melting point can contact and bond with adjacent fibers, playing 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 that of the second fiber filament with a low melting point, which has better strength, so that the liquid-conducting body 1 has good liquid absorption while not being easily deformed.

[0068] In some embodiments, the fiber diameters of the first and second fibers are 10 micrometers to 100 micrometers, and the liquid-conducting body 1 has 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 spatial structure in which solid fibers and air are interwoven. When the density remains constant, 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 and second fibers to be 10 micrometers to 100 micrometers can give the liquid-conducting body 1 a better pore morphology, so that the liquid-conducting body 1 has a better liquid absorption effect.

[0069] In some embodiments, the porosity of the liquid-conducting body 1 ranges from 80% to 99% to achieve better liquid conduction rate and oil retention. Specifically, the liquid-conducting body 1 can be configured with different porosities for a given volume by combining the fiber diameter and fiber quantity 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 micrometers, and the fiber quantity can be designed to be 0.075 grams per cubic centimeter. Based on 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%. The liquid-conducting body 1 can be configured as an oil-retaining cotton, and its volume range can be selected from 0.2 cubic centimeters to 20 cubic centimeters. Depending on the desired liquid conduction and retention effect, 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.

[0070] In some embodiments, 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 first fiber filament and the second fiber filament are made of different materials so that the first fiber filament and the second fiber filament form different melting point temperature differences, and the materials are easy to process.

[0071] See Figure 3-4 The second aspect of this application provides a processing apparatus for a liquid guiding mechanism, used to process the aforementioned liquid guiding mechanism. The liquid guiding mechanism includes a liquid guiding body 1, which includes at least two stacked liquid guiding layers 14. In two adjacent liquid guiding layers 14, the density of the liquid guiding layer 14 closer to the first position 11 is less than the density of the liquid guiding layer 14 farther from the first position 11. The processing apparatus for the liquid guiding mechanism includes a pipe body 2 and at least two conveying channels 21. The conveying channels 21 are disposed within the pipe body 2 and are arranged along the axial direction of the pipe body 2 to facilitate the conveying of the raw material of the liquid guiding layer 14 along the axial direction of the pipe body 2. The number of conveying channels 21 corresponds to the number of liquid guiding layers 14, and each conveying channel 21 is used to convey raw materials of different densities corresponding to different liquid guiding layers 14.

[0072] With this configuration, when the liquid guiding mechanism needs to be processed, raw materials of different densities can be placed in each conveying channel 21 according to the design density requirements of the liquid guiding layer 14. After processing, the raw materials in each conveying channel 21 will form a liquid guiding layer 14 of the corresponding density. In this embodiment, by setting multiple conveying channels 21 to process the liquid guiding body 1 in layers, the layering between each liquid guiding layer 14 can be more clearly defined, and the density of each liquid guiding layer 14 can be more uniform, making the liquid guiding and liquid locking effects of the processed liquid guiding body 1 more accurate and balanced.

[0073] The number of conveying channels 21 and liquid guiding layers 14 can correspond one-to-one, or at least two liquid guiding layers 14 can correspond to one conveying channel 21. For example, when the liquid guiding body 1 includes four liquid guiding layers 14, there can be two conveying channels 21, with each pair of liquid guiding layers 14 corresponding to one conveying channel 21, or there can be four conveying channels 21, with each liquid guiding layer 14 corresponding to one conveying channel 21.

[0074] See Figure 3-4 In some embodiments, the processing apparatus of the liquid guiding mechanism further includes a heating mechanism 3, which heats the liquid guiding body 1 to allow the raw material within the liquid guiding body 1 to expand and adhere. The heating mechanism 3 is connected to the tube body 2, meaning it can be supported by the tube body 2. The heating mechanism 3 is positioned at a first position 11 of the liquid guiding body 1, so that it is close to the liquid guiding body 1 with lower density, creating a temperature difference between the first position 11 and the second position 12. The liquid guiding body 1 at the first position 11 expands first, followed by the liquid guiding body 1 at the second position 12, resulting in a varying density gradient from the first position 11 to the second position 12 for each liquid guiding layer 14. The temperature of the heating mechanism 3 gradually increases along the conveying direction of the raw material in the liquid guiding layer 14. The conveying channel 21 can have an inlet and an outlet, which can be located at both ends of the tube body 2. The conveying direction of the raw material in the liquid guiding layer 14 can be from the inlet to the outlet. In this embodiment, by gradually heating the raw material of the liquid guiding layer 14, the raw material of the liquid guiding layer 14 can be gradually expanded, curled and then gradually bonded, which can make the density of each liquid guiding layer 14 more uniform, so as to make the liquid guiding and liquid locking operation of the processed liquid guiding body 1 more accurate.

[0075] In this embodiment, the heating mechanism 3 may be, but is not limited to, a heating tube or a heating plate. The heating mechanism 3 may include multiple heating sections, each of which may be arranged circumferentially along the tube body 2, and the multiple heating sections may be distributed axially along the tube body 2. Specifically, the heating mechanism 3 may include at least a first heating section 31 and a second heating section 32. The first heating section 31 may be used to heat and pre-expand and curl the raw material of the liquid guiding layer 14, and the second heating section 32 may be used to heat and bond the raw material of the liquid guiding layer 14.

[0076] See Figure 1 and Figure 4 In some embodiments, at least two tubes 2 are provided, and the at least two tubes 2 are nested together. In the at least two nested tubes 2, a gap is provided between adjacent tubes 2 to form a conveying channel 21 so that the conveying channel 21 corresponds to the outline of the liquid guiding layer 14, so that the positions of each liquid guiding layer 14 are more corresponding after processing.

[0077] In this embodiment, each tube 2 can be coaxially arranged to make the thickness of each liquid guiding layer 14 more uniform. The circumferential contours of the inner and outer sides of the delivery channel 21 are the same as the circumferential contours of the inner and outer sides of the liquid guiding layer 14. The circumferential contours of the delivery channel 21 can be, but are not limited to, circular or polygonal.

[0078] See Figure 3-4 In some embodiments, the processing device of the liquid guiding mechanism further includes a partition 22, which is arranged along the axial direction of the tube body 2 to maintain consistency with the conveying direction of the liquid guiding layer 14 and reduce positional interference between the two. The partition 22 is connected between two adjacent tube bodies 2, that is, the two sides of the partition 22 are respectively connected to the sidewalls of the two adjacent tube bodies 2 to separate the conveying channel 21 between the two adjacent tube bodies 2. At least two partitions 22 are arranged along the circumference of the tube body 2 so that the conveying channel 21 forms at least two conveying partitions 211, which facilitates the variable density design of parts with complex cross-sections.

[0079] In this embodiment, each liquid guiding layer 14 can also be divided into at least two liquid guiding strips. Conveying zones 211 are correspondingly set with the liquid guiding strips. Each conveying zone 211 can be used to convey the raw material of the corresponding liquid guiding strip, so that multiple liquid guiding strips of the liquid guiding layer 14 can be heated and processed separately within the corresponding conveying zone 211. This results in a large heating area, uniform heating, and easier expansion and bonding of the liquid guiding layer 14 to the corresponding density, leading to more accurate density processing of the liquid guiding layer 14. Furthermore, by diverting the raw material of each liquid guiding layer 14 through multiple conveying zones 211, the possibility of a large amount of raw material entering the conveying channel 21 and causing blockages is reduced. (See also...) Figure 5 The pipe body 2 is provided with multiple connection points, which can be used to connect the partition 22 to the pipe body 2.

[0080] See Figure 2-3 In some embodiments, the processing device of the liquid guiding mechanism may also include a pressing mold 4, which can be connected to the outlet of the tube body 2 for pressing and molding the expanded material formed by heating, expanding and bonding the raw material of the liquid guiding layer 14, thereby forming finished parts.

[0081] See Figure 1-4 and Figure 6 The processing method for the liquid guiding mechanism provided in the third aspect of this application, based on the above-described processing apparatus for the liquid guiding mechanism, includes:

[0082] The layer density of each liquid guiding layer 14 is obtained. That is, according to the liquid guiding and liquid locking requirements of the liquid guiding body 1, the liquid guiding and liquid locking requirements of each liquid guiding layer 14 can be allocated, and the layer density corresponding to each liquid guiding layer 14 can be matched. Each liquid guiding layer 14 can be processed as a single layer and then combined, or multiple layers can be processed uniformly.

[0083] According to the layer density of each liquid guiding layer 14, the raw material of the liquid guiding layer 14 is allocated to the corresponding conveying channel 21 to perform layer division of the liquid guiding body 1. That is, by putting different amounts of raw material of the liquid guiding layer 14 into each conveying channel 21, the raw material of the liquid guiding layer 14 expands and adheres to form a liquid guiding layer 14 of corresponding density, so that the layer density of the liquid guiding layer 14 is more controllable.

[0084] The raw materials of the liquid guiding layer 14 are heated, and the raw materials of the liquid guiding layer 14 are expanded and bonded together by heating.

[0085] With this configuration, this embodiment distributes different numbers of raw materials for the liquid guiding layer 14 in multiple conveying channels 21 and processes them by heating to form liquid guiding layers 14 with corresponding layer densities. Liquid guiding layers 14 with different layer densities are stacked and combined to form a liquid guiding body 1 with variable density. This makes processing convenient, and the layer density in each liquid guiding layer 14 can form the corresponding required density, so that the density change of the liquid guiding body 1 is more regular. The processed liquid guiding body 1 can better achieve the required liquid guiding and liquid locking effects, which facilitates the balance of the liquid guiding and liquid locking effects of the liquid guiding body 1.

[0086] In some embodiments, obtaining the layer density of the liquid-conducting layer 14 includes:

[0087] By obtaining the overall density variation range of the liquid-conducting body 1, the threshold of the overall density variation range required by the liquid-conducting body 1 can be determined based on the liquid-conducting and liquid-locking requirements of the liquid-conducting body 1.

[0088] Based on the overall density variation range, the layer density of each liquid-conducting layer 14 is determined. That is, based on 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 divided numerically from high to low to form segmented thresholds. The number of segmented thresholds corresponds one-to-one with the number of liquid-conducting layers 14. The layer density of each liquid-conducting layer 14 is selected within the corresponding segmented threshold so that the processed liquid-conducting layers 14 can be combined to meet the liquid-conducting and liquid-locking requirements of the liquid-conducting body 1.

[0089] In some embodiments, the layering of the fluid-conducting body 1 includes:

[0090] The raw material configuration of the liquid guiding layer 14 is fiber filament, which can be configured as the above-mentioned composite fiber 15, or it can be configured as a fiber structure composed of multiple single-material fibers, as long as it can meet the manufacturing needs of the liquid guiding layer 14.

[0091] Based on the layer density of the liquid guiding layer 14, the number of fiber filaments in each conveying channel 21 is determined. Specifically, the layer density of the liquid guiding layer 14 can be directly selected as needed, or it can be calculated based on the required volume and mass of the liquid guiding layer 14. Let the number of fiber filaments be N, the straight weight of a single fiber filament be m, the shrinkage ratio of the fiber filament be η, and the layer density of the liquid guiding layer 14 be ρ. The formula for calculating the number of fiber filaments N is:

[0092] N = ρ / m × η;

[0093] The number of fiber filaments corresponding to the liquid guiding layer 14 can be obtained by the above formula. Then, the fiber filaments can be distributed into each conveying channel 21. Optionally, the fiber filaments can be equally distributed into each conveying channel 21, or the difference in the number of fiber filaments in each conveying channel 21 needs to be within a preset range so that the layer density of the liquid guiding layer 14 meets the usage requirements.

[0094] In some embodiments, heating the raw material in the liquid guiding layer 14 includes:

[0095] The raw material of the liquid guiding layer 14 is heated in segments along its own conveying path. The heating temperature of the raw material of the liquid guiding 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 guiding layer 14. The liquid guiding layer 14 is relatively long. Multiple temperature zones can make the liquid guiding layer 14 more uniformly heated and can also make the liquid guiding layer 14 expand and bond in segments.

[0096] In this embodiment, 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, forming a larger expansion gap. The temperature of the liquid-conducting layer 14 with a higher layer density far away from the heating position is lower, and the raw material will expand later, forming a smaller expansion gap. This allows each liquid-conducting layer 14 to also form a density gradient that changes from the first position 11 to the second position 12.

[0097] In some embodiments, segmented heating of the raw material in the liquid guiding layer 14 along its own transport path includes:

[0098] The material conveying path of the liquid guiding layer 14 is divided into a first heating section and a second heating section. The heating temperature range of the first heating section is 60℃-160℃, which can adapt to the characteristics of the fiber material and make the fiber easier to form pre-expanded curls. The heating temperature range of the second heating section is 120℃-220℃, which can adapt to the characteristics of the fiber material and make the low melting point part of the fiber easier to vitrify and bond.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
