DETAILED DESCRIPTION OF THE INVENTION

(7) In reference to the drawings, according to specific embodiments, the technical solution of the present invention is described clearly and completely below.

Embodiment 1

(8) The present invention discloses a cushion (see FIG. 1), which comprises: a cushion core 1 adopting blasted sponge, and an outer cover layer 2 wrapping the outer layer of the cushion core 1; and the outer cover layer 2 adopts a fiber material which is of a reticular structure. The novel cushion designed by the present invention, which adopts the blasted sponge structure, is convenient to wash directly with water and has super air permeability.ppi mentioned in the present invention is hole number per unit inch. The hardness of the blasted sponge in the present invention is 60 N to 80 N. The outer cover layer is provided with an opening 6, and the opening 6 can be opened and closed by a zipper. The cushion of the present invention is applicable to specific household products, such as seat cushions, pillows, waistrests, mattresses and headrests.

Embodiment 2

(9) The present invention discloses a cushion (see FIGS. 2, 3, 4, 5), which comprises: a cushion core 1 adopting blasted sponge, and an outer cover layer 2 wrapping the outer layer of the cushion core 1; and the outer cover layer 2 adopts a fiber material which is of a reticular structure. The novel cushion designed by the present invention, which adopts the blasted sponge structure, is convenient to wash directly with water and has super air permeability.

(10) The cushion core 1 comprises a main bearing area 4 and an auxiliary bearing area 5. The cushion further comprises a reinforcing skeleton 3, the reinforcing skeleton 3 comprises a plurality of bone bridges 11, and each bone bridge 11 comprises an arch base 12 and an arch bridge 14; the arch bases 12 are located at two side-by-side corners of one side of the cushion core 1, and are close to one side of the main bearing area 4; one end of each arch bridge 14 is connected to the arch base 12, and the other end extends to the diagonal opposite corner of the other side of the cushion core 1, and is close to one side of the auxiliary bearing area 5. The main bearing area 4 and the auxiliary bearing area 5 comprised by the arranged cushion core 1 and the reinforcing skeleton 3 are arranged differentially according to magnitudes of different borne forces. Moreover, the structure of the reinforcing skeleton 3 effectively prevents the defect that after conventional sponge is pressed to deform, the local sponge density of the stressed area is increased, as a result, the local density of the sponge of the area in actual use is high, hardness is increased, water permeability and air permeability become poor, elastic property is poor, and the comfort of the sponge in use will be decreased as well.

(11) The number of the bone bridges 11 is two, and the two bone bridges 11 are arranged crisscross intersected; and two hollow elastic pieces 15 which are superposed vertically are arranged under the intersection between the two bone bridges 11. As the two bone bridges 11 are arranged crisscross and the two hollow elastic pieces 15 which are superposed vertically are arranged under the intersection between the two bone bridges 11, the compression resistance of the main bearing area 4 is higher, and elasticity is better.

(12) Each hollow elastic piece 15 is a hexagonal hollow elastic plastic piece, and the elastic coefficient of the elastic plastic piece is 1.2 times the elastic coefficient of the blasted sponge. As the elastic coefficient which is 1.2 times is set, comfort is better.

(13) Each arch base 12 is provided with a plurality of arch holes 21. The arrangement of the plurality of arch holes 21 further reduces the weight of the arch base 12, and enhances compression resistance. Each arch bridge 14 is provided with a plurality of air-permeable slots 22. Each air-permeable slot 22 is rectangular. The arrangement of the rectangular air-permeable slots 22 effectively improves the air permeability of the local areas of the arch bridges 14. The outer cover layer is provided with an opening 6, and the opening 6 can be opened and closed by a zipper.

(14) When the present embodiment is implemented, the zipper can be opened to take out or install the cushion core, and thereby replacement can be carried out; during use, the arch bridges are upward, the arch bridge surfaces are fronts, the hips or the back of the head of a user press the main bearing area, and the legs or the neck press the auxiliary bearing area.

(15) Although the present invention has been disclosed above with the preferred embodiments, the preferred embodiments are not intended to limit the present invention. Any person killed in the art can utilize the method and technical content disclosed above to make possible alterations and modifications on the technical solution of the present invention without departing from the spirit and scope of the present invention, so any content not departing from the technical solution of the present invention, any simple modifications, equivalent changes and embellishments made on the above-mentioned embodiments according to the technical essence of the present invention, shall fall within the protection scope of the technical solution of the present invention.
