Nonwoven eye pad

Abstract

This invention proposes a nonwoven eye pad, comprising: an eye pad and an edge seal located on the outer side of the eye pad; and a pressure hole formed by thermal extrusion in the middle of the eye pad and the edge seal. The eye pad is composed of multiple layers of cotton nonwoven fabric. The edge seal and the pressure hole cooperate to provide a fulcrum for the eye pad when it is pulled. When the eye pad is pulled, the multiple layers of cotton nonwoven fabric unfold along the interlayer gaps, and the pressure hole holds the surrounding fibers to limit the elongation of the eye pad. Through the cooperation of the edge seal and the pressure hole, the eye pad has a fulcrum when under force. When the eye pad is pulled outward, the multiple layers of nonwoven fabric will unfold along the interlayer gaps to increase the area. Because the fibers at the pressure hole are tightly pressed together by the arc-shaped tip, the strength is higher than that of the surrounding area. It can hold the adjacent fibers like a fixed stake, generating an inward pulling force to prevent the fibers from becoming loose or breaking under pulling.

Description

Technical Field

[0001] This invention relates to the field of eye pads, and more particularly to a nonwoven eye pad. Background Technology

[0002] Most eye pads on the market are made by die-cutting single or multiple layers of material, and mainly serve to cover and adhere to the skin.

[0003] However, existing eye pads are mostly designed with fixed sizes, which makes them poorly adaptable to different eye sockets. They are also prone to fiber breakage or structural deformation when stretched, resulting in a short lifespan. Existing pneumatic eye pads have a simple internal structure, and after inflation, they can only expand as a whole, making it difficult to form a precise arc-shaped protrusion according to the depth of the eye socket. This results in a gap between the middle of the eye pad and the eyeball, and insufficient fit. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a non-woven eye pad.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a non-woven fabric eye pad, comprising: Eye pads and the sealing edge located on the outside of the eye pads; It also includes a pressure hole formed by hot extrusion in the middle of the eye pad and the edge seal. The eye pad is composed of multiple layers of cotton non-woven fabric. The edge seal and the pressure hole work together to provide a fulcrum for the eye pad. When the eye pad is stretched, the multiple layers of cotton non-woven fabric unfold along the gaps between the layers, and the pressure hole pulls the surrounding fibers to limit the elongation of the eye pad.

[0006] Preferably, the eye pad is oval-shaped to fit the human eye, and the pressure hole is a circular recess.

[0007] Preferably, the eye pad has an air bladder inside for supporting it, and the surface of the air bladder is connected to an air tube and an air supply bottle for inflation.

[0008] Preferably, the airbag has an inner square tube inside. When the airbag is filled with air, the gas enters the inner square tube and supports it. The inner square tube then pushes the surface of the eye pad into an arc-shaped protrusion to conform to the contour of the human eye.

[0009] Preferably, the airbag has an outer square tube inside, and the surfaces of the outer and inner square tubes have folding edges for folding. The middle of the folding edge has a circular groove for air intake, and the edge of the circular groove has a support column for support.

[0010] Preferably, the width of the outer square tube is smaller than the width of the inner square tube. The outer square tube is used to support the edge of the airbag, and the protruding inner square tube lifts the surface of the eye pad through the airbag to form an arc-shaped protrusion that fits the contour of the human eye.

[0011] Preferably, the surface of the airbag is provided with a middle ring, and the inside of the middle ring is provided with a middle plate. When the airbag is inflated, the middle ring and the inside of the middle plate are inflated to fit the contour of the eye.

[0012] Preferably, the connection between the airbag and the middle ring is provided with an outer ring, the connection between the middle plate and the middle ring is provided with an inner ring, the surface of the outer ring is provided with a single-pass tube connecting the airbag and the middle ring, the surfaces of the outer ring and the inner ring are provided with a double-pass tube connecting the airbag and the middle plate, and the inside of the double-pass tube and the single-pass tube is provided with an elastic pad that allows unidirectional fluid movement.

[0013] Preferably, the inside of the single-pass tube is provided with a fixed plate, the surface of the fixed plate is provided with air holes for ventilation, and the surface of the fixed plate is provided with connecting posts for pushing open the elastic pad.

[0014] Preferably, the surface of the connecting post is provided with protrusions. When the connecting post moves, the protrusions expand the elastic pad, and gas passes through the gap in the middle of the protrusions.

[0015] Compared with the prior art, the beneficial effects of the present invention include: through the combination of edge sealing and pressing holes, the eye pad has a fulcrum when subjected to force. When the eye pad is pulled outward, the multi-layer non-woven fabric will unfold along the gaps between the layers to increase the area; because the fibers at the pressing holes are tightly pressed together by the arc-shaped tips, the strength is higher than that of the surrounding area, which can hold the adjacent fibers like a fixed stake, generating an inward pulling force to prevent the fibers from becoming loose or broken under pulling. By setting a square tube with folded edges and support columns in the airbag, precise control of the shape of the eye pad is achieved. The inner square tube is wider than the outer square tube, which can push the middle of the eye pad into an arc protrusion, which fits perfectly into the eye socket. With the dual-channel and single-channel airbag, the user only needs to squeeze different parts of the airbag to independently change the protrusion height of the middle ring and the middle plate to fit the user's eye socket.

[0028] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Example 1 According to one embodiment of the present invention, Figures 1-2As shown, this eye pad includes an eye pad 1 and an edge seal 2. The edge seal 2 is formed by hot extrusion and is located at the outer edge of the eye pad 1. The eye pad 1 and the edge seal 2 are located in the middle. The eye pad 1 is formed by hot extrusion. The eye pad 1 is made of multiple layers of cotton non-woven fabric. The multiple layers of cotton non-woven fabric are stacked together. When stretched, the non-woven fabric will unfold, thereby changing the overall size of the eye pad 1.

[0031] The eye pad 1 is made into an oval shape to fit the human eye, and the pressure hole 3 is a circular concave structure, which can not only fix the shape of the middle of the eye pad, but also fit the middle of the eye when used, making it more comfortable to wear.

[0032] Since the perforation 3 is hot-pressed by the arc-shaped tip, the structural strength of the perforation 3 is higher than that of the adjacent fibers. When the non-woven fabric in the middle of the eye pad is pulled apart, the perforation 3 pulls the adjacent fibers, limiting the elongation of the eye pad 1 and ensuring that the eye pad 1 will not be pulled apart during the pulling process.

[0033] With the cooperation of edge sealing 2 and pressing holes 3, the eye pad 1 has a fulcrum when subjected to force. When the eye pad 1 is pulled outward, the original stacked layers of non-woven fabric will unfold along the gaps between the layers, making the overall area of ​​the eye pad 1 larger. Since the pressing holes 3 are extruded by high temperature with arc-shaped tips, they are stronger than the surrounding area. When the non-woven fabric is pulled outward, the pressing holes 3 will tightly hold the adjacent fibers, generating an inward pulling force to prevent the fibers from becoming too loose or being directly torn under the pull. At the same time, it also limits the eye pad 1 from being stretched too long, preventing the entire structure from falling apart.

[0034] Example 2 According to Example 1, Figures 1-6 As shown in the figure, this embodiment also has an air bladder 6 inside the eye pad 1. The air bladder 6 is used to support the eye pad 1. The surface of the air bladder 6 is connected to the air tube 4 and the air supply bottle 5. The air supply bottle 5 and the air tube 4 can inflate the air bladder 6.

[0035] The airbag 6 has an inner square tube 8 and an outer square tube 7 inside. Both the outer square tube 7 and the inner square tube 8 have folded edges 23 on their surfaces. The folded edges 23 can fold and unfold as the airbag 6 is inflated and deflated. There is a circular groove 10 in the middle of the folded edge 23. Gas can enter the square tube 8 and the outer square tube 7 through the circular groove 10. There are support columns 9 on the edge of the circular groove 10. The support columns 9 can support the circular groove 10 and prevent the groove from collapsing. After the gas enters the square tube 8 and the outer square tube 7, the internal pressure of the square tube 8 and the outer square tube 7 increases, and the support column 9 is stretched and lengthened. The folded plate 23 deforms and stretches, increasing the width of the square tube 8 and the outer square tube 7, and lifting the airbag 6. When the gas pressure inside the square tube 8 and the outer square tube 7 decreases, the support column 9 returns to its original shape, pulling the middle part of the folded edge 23, and the square tube 8 and the outer square tube 7 are folded.

[0036] The outer square tube 7 is narrower than the inner square tube 8. The outer square tube 7 is used to support the edge of the airbag 6. After the airbag 6 is filled with gas, the gas enters the inner square tube 8 and supports the inner square tube 8. The inner square tube 8 pushes the surface of the eye pad 1 into an arc-shaped protrusion that conforms to the contour of the human eye.

[0037] By incorporating an inner square tube 8 and an outer square tube 7 with folded edges 23 and support columns 9 inside the airbag 6, the shape of the eye pad 1 can be supported and folded. When gas is inflated into the airbag 6 and penetrates into the inner square tube 8 and outer square tube 7, the air pressure increases and enters the interior of the inner square tube 8 and outer square tube 7, stretching the support column 9 and tearing open the folded edges 23, causing the width of the square tube to increase rapidly, thereby lifting the airbag 6. The support column 9, like a skeleton, expands the air intake channel, preventing the channel from collapsing under pressure. This ensures that airflow can smoothly enter every position of the inner square tube 8 and the outer square tube 7, keeping the support force uniform. Since the inner square tube 8 is wider than the outer square tube 7, the inner square tube 8 can push the middle position of the eye pad 1 higher, forming an arc-shaped protrusion 21, which fits perfectly into the contour of the human eye. When the air is released, the pressure decreases, and the originally elongated support column 9 automatically retracts, pulling the middle part of the folding edge 23 inward, causing the inner square tube 8 and the outer square tube 7 to fold and flatten as a whole.

[0038] Example 3 According to Example 1, Example 2, Figures 1-11 As shown in the figure, this embodiment also has a middle ring 11 disposed on the surface of the airbag 6. The middle ring 11 has a middle plate 14 inside. When the airbag 6 is inflated, gas will enter the middle ring 11 and the middle plate 14, and after expansion, it will fit the contour of the eye.

[0039] An outer ring 12 is fixed at the connection between the airbag 6 and the middle ring 11, and an inner ring 13 is fixed at the connection between the middle plate 14 and the middle ring 11. A single-pass tube 16 passes through the surface of the outer ring 12, connecting the airbag 6 and the middle ring 11. A double-pass tube 15 passes through the surfaces of the outer ring 12 and the inner ring 13, connecting the airbag 6 and the middle plate 14. Both the double-pass tube 15 and the single-pass tube 16 have elastic pads 22 inside. The elastic pads 22 only allow gas to flow in one direction to prevent gas backflow.

[0040] A fixed plate 18 is fixed inside the single-pass tube 16. The surface of the fixed plate 18 has air holes 19 and a connecting post 20. The connecting post 20 can push open the elastic pad 22. The surface of the connecting post 20 has protrusions 21. When the airbag 6 is inflated, the gas pushes the fixed plate 18, causing the fixed plate 18 to deform and move the connecting post 20. The protrusions 21 open the elastic pad 22, allowing the gas to pass through the gaps between the protrusions 21 and enter the interior of the middle ring 11 and the middle plate 14. If the air pressure is too low, the fixed plate... 18. The original shape is restored, the connecting column 20 is disengaged from the elastic pad 22, the middle plate 14, the air bag 6 and the inner ring 13 form the inner box 17, the elastic pad 22 is inclined relative to the single channel 16 and the double channel 15, so that the gas enters the middle ring 11 or the inner box 17 from the air bag 6, so that the elastic pad 22 can be pushed open. When the gas moves from the middle ring 11 or the inner box 17 to the air bag 6, the elastic pad 22 is squeezed by the gas. Since the elastic pad 22 is inclined, the elastic pad 22 is squeezed and blocks the gas from passing through.

[0041] Since the dual channels 15 and the single channel 16 are respectively located at both ends of the airbag 6, the air inside the airbag 6 can be forced into the middle ring 11 or the inner box 17 by squeezing one end of the airbag 6 according to the user's needs, thereby changing the protrusion height of the middle ring 11 and the middle plate 14 according to the user's eye socket.

[0042] 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.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
