[0029] Embodiment 1

[0030] Refer to Figure 1 , a partitioned high-warmth twill-patterned lattice down comforter core, including an upper layer 1 located above, a middle layer 2 located in the middle, and a lower layer 3 located below.

[0031] The middle layer 2 is composed of a bottom cloth 21, a transverse vertical lining 22, and a longitudinal vertical lining 23. The transverse vertical lining 22 and the longitudinal vertical lining 23 intersect horizontally and vertically, dividing the space above the bottom cloth 21 into multiple squares. The lower edges of the transverse vertical lining 22 and the longitudinal vertical lining 23 are connected to the bottom cloth 21; the upper layer 1 is provided with twill patterns 11, and the twill patterns 11 are directly opposite to the squares one by one. Down is filled between the upper layer 1 and the middle layer 2. First, by setting multiple twill patterns 11 filled with down, the effect of fluffiness and warmth retention is achieved; secondly, by setting the transverse vertical lining 22 and the longitudinal vertical lining 23 in the middle layer 2, the transverse vertical lining 22 and the longitudinal vertical lining 23 intersect horizontally and vertically to enclose multiple squares. By setting the squares, the internal space of the squares is larger, more down can be filled, and more air can be effectively stored, further improving the effect of fluffiness and warmth retention.

[0032] There are a total of 72 squares, and the squares are arranged in a matrix of 8 rows and 9 columns each; to prevent the down from moving during use, thereby maintaining the warmth retention and comfort of the quilt.

[0033] Each of the twill patterns 11 has four sides, and at least one pair of pressed pleats 12 is provided on each side; because the pair of pressed pleats 12 are provided on the twill patterns 11, the soft elasticity of the twill patterns 11 is improved, and the comfort of the down comforter core is improved.

[0034] On each of the four sides of the twisted lattice 11, there are two pairs of pressed pleats 12, and the distance between the two pairs of pressed pleats 12 is 2 cm; this further ensures the soft elasticity of the twisted lattice 11.

[0035] The four sides of the twisted lattice 11 are respectively stitched to connect the four sides of the square grid; the twisted lattice 11 and the square grid can be stitched together to fill more down, and the quilt core will not shift during use, maintaining the warmth and comfort of the quilt.

[0036] Both the transverse vertical lining 22 and the longitudinal vertical lining 23 are internally provided with hollow cavities, and the hollow cavities are filled with polyurethane sponge; the polyurethane sponge provides good softness and comfort, making the quilt fit the body better during use and enhancing the overall sleep experience.

[0037] During use, the upper layer 1 is stitched to the middle layer 2. There are vertical linings arranged in a grid on the upper side of the middle layer 2. There are a total of seventy-two grids in an eight-by-nine arrangement. By setting the grids, the internal space of the grids is larger, more down can be filled, more air can be effectively stored, achieving a more fluffy and warm effect. The lining strips of polyurethane sponge provide good softness and comfort, making the quilt fit the body better during use and enhancing the overall sleep experience. And there are 8 pairs of pressed pleats 12 on the twisted lattice 11 on the upper layer 1, and two pairs of pressed pleats 12 are arranged on each stitched surface of the twisted lattice 11, making the twisted lattice 11 in a naturally raised state, improving the soft elasticity of the twisted lattice 11 and the comfort of the down quilt core. Then the inner cloth is stitched below the middle layer 2, and the outer contours of the upper layer 1 and the inner cloth are stitched together to ensure that the down will not leak and extend the service life of the down quilt core.

[0038] Embodiment 2

[0039] Refer to Figure 1 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0040] Part of the lower layer 3 is made of a heat storage honeycomb-shaped far-infrared heating fabric 31; the heat storage honeycomb-shaped far-infrared heating fabric 31 can continuously and stably release far-infrared rays after absorbing energy, can effectively retain heat, reduce heat loss, so that the fabric can maintain a warm effect more durably after heating. The honeycomb-shaped design makes the air flow more smoothly inside the fabric, thereby improving breathability, reducing the sense of stuffiness, and enhancing wearing comfort.

[0041] The lower layer 3 is sequentially divided into a first zone, a second zone, a third zone, a fourth zone, and a fifth zone from the head side to the foot side of the quilt cover. The second zone and the fourth zone are made of a heat storage honeycomb-shaped far-infrared heating fabric 31. The heat storage honeycomb-shaped far-infrared heating fabric 31 can make the areas covering the feet and chest warmer, achieving a better zoned warming effect and effectively solving the pain points of people who are afraid of cold in the feet and chest.

[0042] The length of the first zone is the same as the length of the fifth zone. The lengths of the second zone, the third zone, and the fourth zone are the same. The length of the first zone is equal to half of the length of the second zone, and the length of the first zone is equal to the length of the square grid. This ensures that the warming areas can effectively cover the feet and chest areas, improving the zoned warming effect.

[0043] The four sides of the lower layer 3, the four sides of the bottom cloth 21, and the four sides of the upper layer 1 are respectively sewn together. This ensures that the down will not leak and extends the service life of the down quilt core.

[0044] The lower layer 3 includes an antibacterial fiber cloth layer. The heat storage honeycomb-shaped far-infrared heating fabric 31 is adhered to the antibacterial fiber cloth layer at the second zone and the fourth zone, and the heat storage honeycomb-shaped far-infrared heating fabric 31 is located on the side away from the middle layer 2. The antibacterial fiber cloth layer has antibacterial properties, which can effectively inhibit the growth of microorganisms such as bacteria and fungi, thereby reducing the risk of allergies and infections and providing a more hygienic sleep environment.

[0045] The lower layer 3 is sewn by double-layer fabrics. The sewing threads are strip-shaped and arranged at equal intervals, so that the space between the two-layer fabrics is divided into strip-shaped cells 32. The length of the strip-shaped cell 32 is equal to the length of the first zone, and the strip-shaped cell 32 is filled with down. Filling down in the lower layer 3 also increases the body-hugging comfort of the down quilt core.

[0046] Outer vertical linings are provided at the four sides of the lower layer 3 or the four sides of the upper layer 1, and the four sides of the upper layer 1 and the four sides of the lower layer 3 are connected through the outer vertical linings. By setting the outer vertical linings, the upper layer 1 and the lower layer 3 are connected into a whole. The outer vertical linings enable the periphery of the down quilt core to be filled with enough down, ensuring the warmth retention of the quilt core.

[0047] The height of the horizontal vertical lining 22 is the same as the height of the vertical vertical lining 23. The height of the outer vertical lining is not less than two-thirds of the height of the horizontal vertical lining 22. The thickness of the down filled between the upper layer 1 and the bottom cloth 21 is not greater than 1.5 times the height of the horizontal vertical lining 22. This ensures that the down quilt core can be filled with enough down, effectively store more air, and further improve the fluffy and warm effect.

[0048] When in use, the lower layer 3 includes an antibacterial fiber cloth layer. The antibacterial fiber cloth layer has antibacterial properties and can effectively inhibit the growth of microorganisms such as bacteria and fungi, thereby reducing the risks of allergies and infections and providing a more hygienic sleeping environment. On the second area and the fourth area of the lower layer 3, a heat storage honeycomb-shaped far-infrared heating fabric 31 is stitched on the antibacterial fiber cloth layer. The heat storage honeycomb-shaped far-infrared heating fabric 31 can continuously and stably release far-infrared rays after absorbing energy, effectively retain heat, reduce heat loss, and enable the fabric to maintain a warm effect for a longer time after heating. The honeycomb design allows air to flow more smoothly within the fabric, thereby improving breathability, reducing stuffiness, and enhancing wearing comfort. The lower layer 3 is stitched by a double-layer fabric, and down is also filled in the lower layer 3 to increase the close-fitting comfort of the duvet core.
