Pillow
The present invention relates to a pillow and belongs to the technical field of bedding. The pillow comprises an outer pillow cover and a pillow core, wherein the pillow core is detachably filled in the outer pillow cover. The outer pillow cover comprises a first fabric layer and a second fabric layer, and a first phase-change material layer is arranged on an inner surface of the first fabric layer. The pillow core comprises an elastic material layer and a second phase-change material layer arranged on an outer surface of the elastic material layer. When the second phase-change material layer is close to the first phase-change material layer, the pillow can provide an extremely strong cooling effect. When the second phase-change material layer is far away from the first phase-change material layer, the pillow can provide a moderate cooling effect.
1 . A pillow, comprising an outer pillow cover and a pillow core, wherein the pillow core is detachably filled in the outer pillow cover, the outer pillow cover comprises a first fabric layer and a second fabric layer, and a first phase-change material layer is arranged on an inner surface of the first fabric layer, wherein the first phase-change material layer is discontinuous, wherein the first phase-change material layer comprises a plurality of hexagonal structures arranged in a honeycomb shape, wherein an interior of the hexagonal structure is filled with the first phase-change material, and an exterior of the hexagonal structure is not filled with the first phase-change material; and
the pillow core comprises an elastic material layer and a second phase-change material layer arranged on an outer surface of the elastic material layer.
2 . The pillow according to claim 1 , wherein a ratio of an area of a region filled with the first phase-change material to a total area of the inner surface of the first fabric layer is 30-90%.
3 . The pillow according to claim 1 , wherein the first fabric layer and the second fabric layer are connected by a support layer, the support layer is an annular structure with a thickness, and the first fabric layer, the second fabric layer and the support layer are enclosed to form a cavity adapted to accommodate the pillow core.
4 . The pillow according to claim 3 , wherein the support layer is made of sandwich mesh cloth, and a top and a bottom of the support layer are both provided with continuous piped edges.
5 . The pillow according to claim 1 , further comprising an inner pillow cover for accommodating the pillow core, wherein the inner pillow cover is detachably arranged within the outer pillow cover.
6 . The pillow according to claim 1 , wherein the second fabric layer comprises an elastic material strip that protrudes in a direction away from the outer pillow cover.
7 . The pillow according to claim 1 , wherein the pillow comprises in sequence:
a knitted nylon-spandex fabric layer, the first phase-change material layer, the second phase-change material layer, the elastic material layer and a knitted breathable fabric layer.
8 . The pillow according to claim 1 , wherein the pillow comprises in sequence:
a knitted nylon-spandex fabric layer, the first phase-change material layer, the elastic material layer, the second phase-change material layer and a knitted breathable fabric layer.
9 . The pillow according to claim 1 , wherein the pillow comprises in sequence:
a knitted nylon-spandex fabric layer, the first phase-change material layer, a first mesh fabric layer, the second phase-change material layer, the elastic material layer, a second mesh fabric layer and a knitted breathable fabric layer.
10 . The pillow according to claim 1 , wherein the pillow comprises in sequence:
a knitted nylon-spandex fabric layer, the first phase-change material layer, a first mesh fabric layer, the elastic material layer, the second phase-change material layer, a second mesh fabric layer and a knitted breathable fabric layer.
