An object of the utility model is to provide a high density sponge of breathing freely to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a high-density breathable sponge comprises a first high-density sponge layer and a second high-density sponge layer; a first cavity and a second cavity are arranged between the first high-density sponge layer and the second high-density sponge layer at intervals; the first cavity and the second cavity are filled with fiber yarns made of ethylene-vinyl acetate copolymer, and the fiber yarns are of a net structure.

As the utility model discloses a preferred technical scheme: and the second high-density sponge layer is also provided with air holes.

As the utility model discloses a preferred technical scheme: and the air holes are filled with air-permeable materials.

As the utility model discloses a preferred technical scheme: the air holes are filled with spices.

As the utility model discloses a preferred technical scheme: the first cavity is arranged in an elliptical shape.

As the utility model discloses a preferred technical scheme: the second cavity is arranged in a circle.

As the utility model discloses a preferred technical scheme: the first cavity is tangent to the second cavity end to end, and an exhaust area is formed between the first cavity and the second cavity.

As the utility model discloses an preferred technical scheme: the first high-density sponge layer and the second high-density sponge layer are sewn on the side faces of the first cavity and the second cavity.

Adopt above-mentioned technical scheme, the beneficial effects of the utility model are that: through the mode, the air permeability of the sponge is enhanced while the hardness of the original sponge is ensured, and particularly, the sponge has lasting non-deforming elasticity due to the adoption of the fiber yarns made of the ethylene-vinyl acetate copolymer; therefore, the problem that the mattress made of the existing sponge is easy to deform after being used for a long time is solved.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrated; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1, the present invention provides an embodiment: a high-density breathable sponge comprises a first high-density sponge layer 1 and a second high-density sponge layer 4; a first cavity 2 and a second cavity 3 are arranged between the first high-density sponge layer 1 and the second high-density sponge layer 4 at intervals; the first cavity 2 and the second cavity 3 are filled with fiber yarns made of ethylene-vinyl acetate copolymer, and the fiber yarns are of a net structure.

In conclusion, the sponge can ensure the hardness of the original sponge and enhance the air permeability of the sponge, and particularly, the sponge has lasting and non-deforming elasticity due to the adoption of the cellosilk made of the ethylene-vinyl acetate copolymer; thus solving the problem that the mattress can not deform after being used for a long time when being made into a mattress.

In order to further enhance the air permeability of the second high-density sponge layer 4, air holes 5 are further formed in the second high-density sponge layer 4, wherein the air holes 5 are uniformly distributed in the second high-density sponge layer 4.

Because the bleeder vent 5 intussuseption is filled with ventilative material, consequently can utilize ventilative material such as conventional sponge, can also promote its gas permeability when realizing hair filtration, especially, when adopting the material with first high density sponge layer 1 is filled bleeder vent 5, still has the bearing capacity of strengthening first high density sponge layer 1 when realizing above-mentioned effect.

On the basis of the scheme, as the air holes 5 are filled with spices, for example, when the sponge is made into a mattress, the air holes 5 can be filled with some spices which are helpful for sleeping, such as lavender, origanum vulgaris, sage and the like; when the sponge is made into insole, the air holes 5 can be filled with deodorizing and dehumidifying material.

Because the first cavity 2 is oval, the supporting capacity of the first cavity 2 for two high-density sponge layers can be enlarged, and the filling of the fiber yarns is facilitated. Simultaneously the second cavity 3 sets to circular and the first cavity 2 of ellipse shape and mutually supports, and then makes the support ability and the adaptability of this sponge all obtain improving.

Furthermore, the first cavity 2 and the second cavity 3 are tangent end to end, an exhaust area 6 is formed between the first cavity 2 and the second cavity 3, and when the air holes 5 introduce air into the exhaust area 6, the air permeability of the sponge can be improved.

In order to ensure the stability of the sponge structure, the first high-density sponge layer 1 and the second high-density sponge layer 4 are sewn on the side surfaces of the first cavity 2 and the second cavity 3. Because the first high-density sponge layer 1 and the second high-density sponge layer 4 are fixed together by utilizing a sewing mode, the first high-density sponge layer 1 and the second high-density sponge layer 4 can be taken down from the two cavities, and the first high-density sponge layer 1 and the second high-density sponge layer 4 can be disassembled and assembled conveniently by the mode. Thereby facilitating the cleaning and disinfection of the sponge. Especially, the decomposition of the organic silicon is convenient for complete exposure to the sun.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
