Description

Technical Field

[0001] This utility model relates to the field of biomimetic fiber structure technology, and in particular to an environmentally friendly, multi-purpose biomimetic fiber structure. Background Technology

[0002] Currently, various fabrics require the use of fibers in their production process. Fibers mainly include natural fibers and man-made fibers, with man-made fibers becoming the mainstream.

[0003] A search revealed Chinese Patent Publication No. CN219621332U, which discloses an environmentally friendly multi-purpose biomimetic fiber structure, comprising an environmentally friendly multi-purpose biomimetic fiber monofilament. The monofilament includes a hollow filament, a polyester core wrapped around the hollow filament, and a sheath wrapped around the polyester core. One end of the monofilament is connected to a protrusion, with a grooved block bolted inside the protrusion and a sealing block slidably connected to the outside of the grooved block. The hollow structure allows for the formation of an insulating air layer inside the monofilament. Furthermore, the protrusion structure allows for the injection of hot air into the monofilament as needed, accelerating its expansion and making the resulting fabric denser, locking in heat and reducing heat loss.

[0004] However, this technical solution still has the following drawbacks when in use:

[0005] (1) When this technical solution is used, the worm gear inside the adjustment mechanism is actively rotated to block the hole of the protrusion to avoid heat loss during the non-hot air injection stage. Such a design cannot achieve automatic control, especially when the airflow needs to be adjusted frequently, the manual operation is inefficient.

[0006] (2) During the hot air injection process, the technical solution does not have a pressure balance structure. When air is discharged by relying solely on the air pores inside the fiber structure, it cannot be matched with the hot air blower with atmospheric flow. When the internal air pressure rises too quickly during the hot air heating process, it will cause the fiber to burst or the sealing structure to be damaged. Summary of the Invention

[0007] In order to solve one or more technical problems existing in the prior art, one of the purposes of this application is to provide an automatic opening and closing gas pipeline passage adapted to a hot air blower, which does not require manual intervention and significantly improves operating efficiency.

[0008] The second objective of this application is to provide an upper threaded stop that can help to quickly expel internal cold air, thereby preventing the fibers from bursting due to excessively rapid hot air injection.

[0009] To address the aforementioned technical problems, the following technical solutions are adopted to achieve one and two objectives of this application:

[0010] An environmentally friendly, multi-purpose biomimetic fiber structure includes: an environmentally friendly biomimetic fiber monofilament, wherein the environmentally friendly biomimetic fiber monofilament includes an inner hollow filament, an outer sheath is provided on the outside of the inner hollow filament, and a central polyester core is filled between the inner hollow filament and the outer sheath.

[0011] The environmentally friendly biomimetic fiber monofilament is fixedly connected to a connecting vent housing on its side. A spring mounting cavity is opened on the inner side of the connecting vent housing. Side connecting vent holes are symmetrically opened on both sides of the spring mounting cavity. An upper connecting vent hole is opened above the spring mounting cavity, extending through to the top of the connecting vent housing. Reinforcing rings are symmetrically fixedly connected to both sides of the connecting vent housing. A support spring is fixedly connected to the bottom wall of the spring mounting cavity. A rubber sealing block is fixedly connected to the upper end of the support spring. Two sets of venting grooves are symmetrically opened above the rubber sealing block. An upper threaded stop block is provided above the upper connecting vent hole.

[0012] Preferably, the side-connecting air hole is adapted to and communicates with the inner side of the internal hollow filament.

[0013] Preferably, the inner side of the reinforcing ring is fixedly connected to the outer side of the corresponding environmentally friendly biomimetic fiber monofilament.

[0014] Preferably, the rubber sealing block is a splicing design of two sets of cylinders that are narrow at the top and wide at the bottom. The size of the narrow cylinder at the top of the rubber sealing block is adapted to the size of the upper connecting vent hole, and the vent groove is only opened on the outer side of the narrow cylinder at the top of the rubber sealing block.

[0015] Preferably, when the support spring naturally elongates without being subjected to external force, the lower wide-mouth cylinder of the rubber sealing block is tightly attached to the top wall of the spring mounting cavity, sealing the lower end of the upper connecting air hole.

[0016] Preferably, the upper connecting vent has an internal thread on its inner side, the upper threaded block has four sets of slots on its outer side that are adapted to the vent groove, and the upper threaded block has an external thread on its outer side that is adapted to the internal thread on the inner side of the upper connecting vent.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1): In this utility model, the gas pipeline passage is automatically opened when hot gas is injected and automatically closed when hot gas is shut off, without the need for manual intervention, which significantly improves the efficiency of operation and avoids the tediousness and error of manual adjustment.

[0019] (2): In this utility model, by screwing in the upper threaded stop and pressing down the rubber sealing block, the internal cold air can be quickly discharged, avoiding fiber expansion and cracking due to excessive hot air injection rate. The cooperation of multiple sets of connecting ventilation shells and upper threaded stop blocks supports simultaneous heating and exhaust of multiple fibers, adapting to the needs of large-scale production.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] Example: Refer to Figures 1 to 4 In this embodiment of the present invention, an environmentally friendly multi-purpose biomimetic fiber structure includes: an environmentally friendly biomimetic fiber monofilament 1, the environmentally friendly biomimetic fiber monofilament 1 including an inner hollow filament 11, an outer sheath 13 disposed on the outside of the inner hollow filament 11, and a central polyester core 12 filled between the inner hollow filament 11 and the outer sheath 13.

[0029] An environmentally friendly biomimetic fiber monofilament 1 is fixedly connected to a connecting ventilated housing 2 on its side. A spring mounting cavity 3 is opened on the inner side of the connecting ventilated housing 2. Side connecting vents 4 are symmetrically opened on both sides of the spring mounting cavity 3. An upper connecting vent 5 is opened above the spring mounting cavity 3, extending through to the top of the connecting ventilated housing 2. Reinforcing rings 6 are symmetrically fixedly connected to both sides of the connecting ventilated housing 2. A support spring 7 is fixedly connected to the lower bottom wall of the spring mounting cavity 3. A rubber sealing block 8 is fixedly connected to the upper end of the support spring 7. Two sets of venting grooves 9 are symmetrically opened above the rubber sealing block 8. An upper threaded stop 10 is set above the upper connecting vent 5. When an external hot air blower passes through the upper connecting vent 5 into the interior... When hot air is injected into the hollow filament 11, the hot air sequentially heats the inner hollow filament 11, the middle polyester core 12, and the outer sheath 13. The middle polyester core 12 expands due to heat, pushing the outer sheath 13 to expand, increasing the density between fibers. The connecting vent housing 2 is connected to the inner hollow filament 11 through the side connecting air hole 4. The elastic force of the supporting spring 7 keeps the rubber sealing block 8 tightly attached to the top of the spring mounting cavity 3 under normal conditions, blocking the airflow. When hot air is injected, the airflow will press down on the rubber sealing block 8 to open the vent groove 9, and the hot air enters the inner hollow filament 11 through the side connecting air hole 4. After the air supply stops, the spring resets and automatically seals, achieving precise control of fiber expansion and contraction without manual operation.

[0030] The side-connecting air hole 4 is adapted to and connected to the inner side of the internal hollow filament 11. The connection between the side-connecting air hole 4 and the internal hollow filament 11 allows hot air to flow directly into the hollow cavity, avoiding heat loss at the connection point. The hot air is evenly distributed in the axial space of the internal hollow filament 11 through the side-connecting air hole 4, causing the central polyester core 12 to expand evenly under heat, avoiding local overheating and deformation of the fiber, and improving the heat conduction efficiency.

[0031] The inner side of the reinforcing ring 6 is fixedly connected to the outer side of the corresponding environmentally friendly biomimetic fiber monofilament 1. The reinforcing ring 6 is fixed to the outer side of the environmentally friendly biomimetic fiber monofilament 1 by mechanical snap-fit, which enhances the bonding strength between the ventilated shell 2 and the fiber. When the fiber expands due to heat, the reinforcing ring 6 counteracts the shear force generated by the radial expansion of the central polyester core 12, prevents the shell from falling off, and ensures the airtightness between the side connecting air hole 4 and the internal hollow filament 11.

[0032] The rubber sealing block 8 is a splicing design of two sets of cylinders that are narrow at the top and wide at the bottom. The size of the narrow cylinder at the top of the rubber sealing block 8 is adapted to the size of the upper connecting air hole 5. The air vent 9 is only opened on the outer side of the narrow cylinder at the top of the rubber sealing block 8. When the support spring 7 is compressed, the stepped structure of the rubber sealing block 8 causes the lower wide cylinder to detach from the top wall of the spring mounting cavity 3, forming an airflow channel. At the same time, the symmetrical distribution of the air vent 9 balances the air pressure and prevents the sealing block from tilting and getting stuck.

[0033] The upper connecting vent 5 has an internal thread on its inner side, and the upper threaded stop 10 has four sets of slots on its outer side that are compatible with the vent groove 9. The upper threaded stop 10 also has an external thread on its outer side that is compatible with the internal thread on the inner side of the upper connecting vent 5. When it is necessary to discharge the internal cold air, the upper threaded stop 10 is screwed in and the rubber sealing block 8 is pressed down. The cold air flows through the side connecting vent 4 into the vent groove 9 and is discharged from the slot of the upper threaded stop 10. The threaded connection ensures that the sealing block is in a stable downward state. The slot and the vent groove 9 are aligned to form a directional exhaust path, realizing bidirectional control of the airflow. This avoids the fiber pores from bursting due to the excessively fast rate of hot air entering the interior.

[0034] The working principle of this utility model is as follows: In the initial state, the elastic force of the supporting spring 7 makes the rubber sealing block 8 tightly adhere to the top of the spring mounting cavity 3, blocking the airflow channel between the upper connecting air hole 5 and the side connecting air hole 4. The environmentally friendly biomimetic fiber monofilament 1 is in an uninflated state, and the internal hollow filament 11, the middle polyester core 12 and the outer skin 13 maintain their initial shape, with low density between fibers.

[0035] When entering the hot air injection stage, the pipe of the external hot air blower is tightly connected to the upper connecting vent 5. When the hot air in the pipe is discharged, it will press down the rubber sealing block 8, causing the support spring 7 to compress. The lower wide cylinder of the rubber sealing block 8 is separated from the top wall of the spring mounting cavity 3, forming an airflow channel. The hot air enters the spring mounting cavity 3 through the upper connecting vent 5, flows to the side connecting vent 4 through the vent groove 9, and is finally evenly distributed in the axial space of the internal hollow filament 11. The hot air heats the internal hollow filament 11, the middle polyester core 12 and the outer skin 13 in sequence. The middle polyester core 12 expands when heated, pushing the outer skin 13 to expand, increasing the density between fibers and improving the heat preservation performance.

[0036] The stepped structure of the rubber sealing block 8 forms a stable airflow channel when the support spring 7 is compressed. The symmetrical distribution of the vent grooves 9 balances the air pressure and prevents the sealing block from tilting and getting stuck. By adjusting the airflow rate of the hot air blower, the expansion range of the internal hollow filaments 11 is controlled, so as to prevent the fibers from being damaged due to excessive expansion caused by the inability of gas to be discharged.

[0037] When a large airflow is needed to rapidly heat the environmentally friendly biomimetic fiber monofilament 1, the upper threaded block 10 above the connecting air hole 5 of other groups that are not connected to the hot air blower can be tightened to press down the rubber sealing block 8, compress the support spring 7, and open the airflow channel. At this time, the cold airflow in the hollow filament 11 enters the ventilation groove 9 through the side connecting air hole 4 and is discharged from the slot of the upper threaded block 10. The threaded connection ensures that the sealing block is in a stable downward state. The slot is aligned with the ventilation groove 9 to form a directional exhaust path, avoiding fiber expansion and cracking due to excessive hot air entry rate.

[0038] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
