[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] According to an embodiment of the present utility model, an elastic soft pad made of plant fibers is provided.

[0023] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners. As Figures 1-4 shown, an elastic soft pad made of plant fibers according to an embodiment of the present utility model includes a plant fiber cushion core 1 and a wrapper 2. The plant fiber cushion core 1 is formed by laminating and hot-pressing a plurality of unit plant fiber layers 7 in sequence, and a plurality of flat tubes 8 are arranged at equal intervals between adjacent unit plant fiber layers 7. A non-stick coating 10 is coated on the surface of each flat tube 8, and a pulling convex block 9 is integrally formed at one end of each flat tube 8. The outer surface of the plant fiber cushion core 1 is sleeved with a wrapper 2, and a sponge layer 5 is sewn on the inner surface of the wrapper 2. A plurality of eyelid holes 6 are formed between adjacent two unit plant fiber layers 7 through the flat tubes 8. By using a flat tube 8 with a cross-section of an eyelid structure, compared with the prior art, in order to prevent the hollow tube from being crushed under pressure, its diameter will be reduced as much as possible, resulting in a smaller inner diameter of the cavity, and thus the overall elastic performance of the elastic soft pad made of plant fibers is lower than that of the plant fiber cushion core 1 proposed in this application. The reason is that the flat tube 8 has a higher pressure-bearing performance than the cylindrical hollow tube and can form larger-sized eyelid holes 6 to improve the elastic effect. In order to further improve the elastic performance, an elastic body made of silica gel or rubber can also be filled in the eyelid holes 6;

[0024] In one embodiment, an installation strip opening 3 is provided on the wrapper 2, and a shading piece 4 covers the periphery of the installation strip opening 3. The shading piece 4 is sewn and connected to the outer surface of the wrapper 2, and one end of the shading piece 4 facing the installation strip opening 3 is reserved with an opening. The length of the installation strip opening 3 matches the width of the plant fiber cushion core 1. Through the settings of the installation strip opening 3 and the shading piece 4, it is easy to install the wrapper 2 and improve the aesthetics.

[0025] In one embodiment, a plurality of eyelid holes 6 are provided in the plant fiber cushion core 1, and the plurality of eyelid holes 6 are distributed between several unit plant fiber layers 7. Through the plurality of eyelid holes 6, a multi-layer and multi-group eyelid hole 6 structure is formed, so that the overall plant fiber cushion core 1 is in a hollow structure, improving the elastic effect.

[0026] In one embodiment, the non-stick coating 10 is made of Teflon or polytetrafluoroethylene. By providing the non-stick coating 10, the surface smoothness of the flat tube 8 can be improved, and adhesion to the glue liquid filled inside the plant fiber cushion core 1 can be avoided.

[0027] In one embodiment, a pulling convex block 9 is provided on each of the two sides of the flat tube 8, and the thickness of the two pulling convex blocks 9 is less than the thickness of two adjacent unit plant fiber layers 7. By providing the pulling convex block 9, it is easy to pull the flat tube 8 out of the eyelid hole 6.

[0028] In one embodiment, both ends of the flat tube 8 are open structures, and the length of the flat tube 8 is adapted to the size of the plant fiber cushion core 1. Through the flat tube 8 with open ends at both ends, it is easy to discharge the air inside the flat tube 8 during the hot pressing stage.

[0029] Working principle:

[0030] During use, by inserting the plant fiber cushion core 1 into the installation strip opening 3 provided on the surface of the wrapper 2, the wrapper 2 is wrapped around the outer surface of the plant fiber cushion core 1. By combining the multi-layer eyelid holes 6 of the plant fiber cushion core 1 and the sponge layer 5 on the inner surface of the wrapper 2, the elastic performance of the plant fiber soft cushion can be easily improved. During the production stage of the plant fiber cushion core 1, since the plant fiber cushion core 1 is formed by sequentially hot pressing several stacked unit plant fiber layers 7, and several flat tubes 8 are equidistantly laid between two adjacent unit plant fiber layers 7 as components for forming the eyelid holes 6. On the one hand, the flat tube 8 has a good deformation effect under force, avoiding the phenomenon of overpressure and fragmentation. On the other hand, by providing the pulling convex block 9 and the non-stick coating 10, adhesion to the glue liquid filled inside the plant fiber cushion core 1 is avoided to the greatest extent, and it is easy to pull out of the eyelid hole 6, facilitating the formation of the eyelid hole 6, and it is easy to add an elastic body into the eyelid hole 6 to improve the elastic performance of the plant fiber elastic soft cushion.
