[0035] At present, the duvet has become the lightest and warmest type of quilt core in bedding products. The duvet is highly regarded for its excellent warmth retention, lightness, and breathability. The good warmth retention of the duvet is because its filling, down, has a unique spherical fiber structure. Each down filament is composed of many overlapping scales, and each scale is hollow. This hollow scale structure enables down to hold a large amount of static air. Air itself does not conduct heat, and down also hinders air convection, so down forms a natural heat insulation and warmth retention barrier outside the human body to block the flow of hot and cold air.
[0036] Currently, the common styles and processes of duvets on the market mainly include box quilting and through-cut quilting. Both of these processes form a duvet by quilting the down between two layers of fabric. The box quilting process divides the duvet core into multiple boxes, and the down is filled in multiple boxes. In actual use, due to the down filling in the boxes and bulging, the duvet core is only easy to bend at the quilting seams, and the boxes of the duvet core are not easy to bend due to the expansion of the down, resulting in a weak wrapping effect on the human body when using the duvet.
[0037] Especially at the shoulder and neck positions on both sides of the human body, the box-shaped duvet cannot fit closely with the human body, and air leakage is likely to occur. In the actual use scenario of the duvet, many people will encounter the situation of not being warm due to air leakage on both sides of the shoulders during sleep, so they will turn and press the duvet on both sides of the shoulder and neck under their bodies.
[0038] In view of the above situation, the present application provides a partitioned warmth retention duvet core to improve the wrapping effect of the duvet core on the human body, and further improve the warmth retention effect of the duvet core. The following combines Figure 1 - Figure 2 , and details the basic structure, working principle, and technical effects achieved by the partitioned warmth retention duvet core provided by the present application.
[0039] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural view of the partitioned warmth retention duvet core in the embodiment of the present application, Figure 2 and Figure 1 is a cross-sectional view of the partitioned warmth retention duvet core in the embodiment of the present application. As shown in Figure 2As shown, in this embodiment, the partitioned thermal insulation duvet core includes an upper layer 100, a lower layer 200, and a filling material. The upper layer 100 and the lower layer 200 are disposed opposite to each other. In this embodiment, the edges of the upper layer 100 and the lower layer 200 are directly stitched and connected, so as to form a filling cavity for accommodating the filling material between the upper layer 100 and the lower layer 200. In other embodiments, according to different design styles and different usage scenarios of the duvet core, the edges of the upper layer 100 and the lower layer 200 can also be stitched and connected in a standing height style. At this time, the height of the standing height is selected to be 1 cm - 10 cm according to the design requirements.
[0040] Please refer to Figure 1 and Figure 2 , in this embodiment, a first standing strip 300 and a second standing strip 400 are disposed between the upper layer 100 and the lower layer 200. Multiple first standing strips 300 are arranged at intervals along the length direction of the duvet core. Both sides of the multiple first standing strips 300 are respectively connected to the upper layer 100 and the lower layer 200. Multiple second standing strips 400 are connected and arranged between two adjacent first standing strips 300. The multiple second standing strips 400 are arranged at intervals. The length directions of the multiple second standing strips 400 are all perpendicular to the length direction of the first standing strip 300, and both sides of the second standing strip 400 are respectively connected to the upper layer 100 and the lower layer 200. Thus, the first standing strip 300 and the second standing strip 400 divide the filling cavity into multiple square grid chambers.
[0041] Furthermore, in order to improve the wrapping property of the duvet core, and thus improve the thermal insulation property of the duvet core. Please refer to Figure 1 , the multiple square grid chambers include multiple thermal insulation chambers 500 and multiple wrapping chambers 600. The multiple thermal insulation chambers 500 are located in the middle of the duvet core. The multiple wrapping chambers 600 are distributed on both sides of the multiple thermal insulation chambers 500. The length and width dimensions of the thermal insulation chambers 500 are larger than the length and width dimensions of the wrapping chambers 600, that is, the volume of the thermal insulation chambers 500 is larger than the volume of the wrapping chambers 600. Filling materials are filled in both the thermal insulation chambers 500 and the wrapping chambers 600. The thermal insulation chambers 500 located in the middle of the duvet core have a large volume and can be filled with more filling materials, having a good thermal insulation effect; while the quilting at the wrapping chambers 600 on both sides of the duvet core is denser, and the duvet core is easily bent along the quilting, so that the wrapping property at the wrapping chambers 600 on both sides of the duvet core is better. Thus, the duvet core in this embodiment has both thermal insulation property and wrapping property, improving the comfort and thermal insulation property of the user during use.
[0042] During the use of the down comforter core, the heat preservation cavity 500 is located directly above the human body, and the wrapping cavity 600 is located on both sides of the user's shoulder and neck. The down comforter core is prone to bending along the quilting, so that multiple wrapping cavities 600 in the shape of dense small squares wrap around the turning parts on both sides of the user's shoulders and necks, making the wrapping of the two sides of the down comforter core on the user's shoulders and necks stronger. Thus, it improves the situation that the wrapping on both sides of the user's shoulders and necks is not strong and air leakage is easy to occur when using the current square vertical-lined down comforter, and enhances the heat preservation effect of the down comforter core.
[0043] Please refer to Figure 1 and Figure 2 For further improvement, the length direction of the heat preservation cavity 500 is consistent with the width direction of the down comforter core. Multiple heat preservation cavities 500 are arranged side by side along the length direction of the filling cavity. In this embodiment, two columns of heat preservation cavities 500 are arranged side by side along the width direction of the down comforter core. The wrapping cavities 600 are distributed on both sides of the two rows of heat preservation cavities 500, and the length direction of the wrapping cavities 600 is arranged along the length direction of the down comforter core. The length direction of the wrapping cavities 600 is consistent with the length direction of the down comforter core, so that the distance between adjacent first vertical-lined strips 300 in the width direction of the down comforter core is smaller, and thus the bending radius of the wrapping cavity 600 area of the down comforter core is smaller, further enhancing the wrapping property of the down comforter core, and then enhancing the heat preservation performance of the down comforter core.
[0044] Please refer to Figure 1 and Figure 2 For further improvement, the wrapping cavities 600 on both sides of the same vertical-lined strip are arranged staggeredly. The staggeredly arranged wrapping cavities 600 can effectively prevent the filling secondary materials from moving left and right during use, reducing the possibility of the down comforter core losing its fluff and resulting in a decline in the heat preservation performance of the down comforter core.
[0045] In Figure 1 In a more specific embodiment shown, the length of the second vertical-lined strip 400 at the side wall of the heat preservation cavity 500 is 60 cm - 80 cm, that is, the length of the heat preservation cavity 500 is 60 cm - 80 cm. Since there are two rows of heat preservation cavities 500 arranged side by side, the width of the overall heat preservation cavity 500 area is 120 cm - 160 cm. The heat preservation cavity 500 has a large volume and can accommodate more fillers, making the heat preservation area have good heat preservation performance. The length of the second vertical-lined strip 400 at the side wall of the wrapping cavity 600 is 15 cm - 25 cm, that is, the width of the wrapping cavity 600 is 15 cm - 25 cm, making the quilting gap at the wrapping cavity 600 of the down comforter core small, facilitating the bending of the down comforter core at the wrapping cavity 600 and then fitting to the human body.
[0046] In traditional down comforter cores, due to the lack of filling materials at the quilting areas, there are problems with poor heat preservation at the quilting areas. In this embodiment, since there are multiple first vertical lining strips 300 and second vertical lining strips 400 provided in the down comforter core, and there is a lack of filling materials at the first vertical lining strips 300 and the second vertical lining strips 400, the heat preservation at the first vertical lining strips 300 and the second vertical lining strips 400 is also lacking. Based on this, please refer to Figure 1 and Figure 2 , at both ends of the second vertical lining strip 400 on the upper layer 100, folding pleats 700 are provided. The pleating method is a single-sided pleat. The width of the folding pleats 700 is 0.5 cm - 10 cm. The setting of the folding pleats 700 forms multiple arches on the upper layer 100 of the down comforter core, thereby increasing the internal space of the down comforter core, and further enabling an increase in the filling amount of the down comforter core and improving the heat preservation effect of the down comforter core. At the same time, the fabric folded out by the folding pleats 700 will block the first vertical lining strip 300, thereby changing the layer structure at the relative position of the upper layer 100 and the first vertical lining strip 300, and forming an air flow heat storage groove at the relative position of the upper layer 100 and the first vertical lining strip 300. The air flow heat storage groove part can accommodate a certain amount of air, playing a similar role to that of the down in fixing air for heat preservation. In other embodiments, down can also be filled in the air flow heat storage groove formed by the pleats, further improving the heat preservation effect of the down comforter core and improving the disadvantage of poor heat preservation at the quilting areas in traditional down comforter cores.
[0047] Furthermore, since the pleating process is carried out on the upper layer 100 in this embodiment, the fabric used for the upper layer 100 in this embodiment is 105% - 150% of the fabric used for the upper layer 100 in the normal vertical lining process or the cut-through process, and the extra part of the fabric serves as the pleated part necessary for the pleating process.
[0048] Furthermore, in this embodiment, the fabrics used for the upper layer 100 and the lower layer 200 of the down comforter core are one or two of cotton fabrics, polyester-cotton fabrics, polyester fabrics, etc. The specific materials can be selected according to the product positioning. The fabrics used for the first vertical lining strip 300 and the second vertical lining strip 400 are one of polyester fabrics, cotton fabrics, nylon fabrics, etc. The filling material in the down comforter core is one or several of grey goose down, grey duck down, white goose down, white duck down, etc. The specific filling is selected according to the actual design requirements.
[0049] The working principle of a partitioned thermal insulation down comforter core is as follows: A first vertical lining strip 300 and a second vertical lining strip 400 are provided between the upper layer 100 and the lower layer 200, dividing the down comforter core into a middle thermal insulation cavity 500 and wrapping cavities 600 located on both sides of the thermal insulation cavity 500. The thermal insulation cavity 500 has a large volume and a large amount of filled down, resulting in good thermal insulation effect at the thermal insulation cavity 500 of the down comforter core; The quilting at the wrapping cavity 600 of the down comforter core is denser, facilitating bending at the wrapping cavity 600 and conforming to the human body, improving the wrapping property on both sides of the down comforter core, and thus enhancing the thermal insulation performance of the down comforter core.
[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
