Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bedding, and more specifically, to a heat storage and warmth-keeping down quilt core. Background Art
[0002] A down quilt is a quilt filled with down, which is the lightest and warmest quilt core category among current bedding products. With its excellent warmth retention, lightness, and breathability, the down quilt has become the first choice for more and more people pursuing high-quality sleep. Currently, most of the styles and processing techniques of down quilts on the market mainly use through-cut quilting, which wraps the down in two layers of fabric to form a down quilt through quilting.
[0003] The through-cut quilting process directly stitches two layers of fabric together, and the cross-sectional shape of the quilt core is flat, greatly reducing the internal space of the quilt, limiting the stretching space of the down in the quilt core, and thus resulting in poor heat storage and warmth-keeping effects of the down quilt. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a heat storage and warmth-keeping down quilt core, which can improve the heat storage and warmth-keeping effects of the down quilt.
[0005] The embodiments of the utility model are implemented as follows:
[0006] In a first aspect, the utility model provides a heat storage and warmth-keeping down quilt core, including:
[0007] A lower layer and an upper layer arranged opposite to each other;
[0008] A first vertical lining strip, and a plurality of first vertical lining strips are arranged in parallel and at intervals between the lower layer and the upper layer;
[0009] A second vertical lining strip, and a plurality of second vertical lining strips are arranged at intervals between two adjacent first vertical lining strips;
[0010] Wherein, the first vertical lining strip and the second vertical lining strip separate a plurality of filling cavities between the upper layer and the lower layer. The first vertical lining strip and the second vertical lining strip have different heights, causing the upper layer to arch at positions corresponding to the filling cavities, forming an arched cavity communicating with the filling cavities, and the filling cavities are filled with heat-preserving materials.
[0011] In an alternative embodiment, the filling cavities on both sides of the same first vertical lining strip are arranged in a staggered manner.
[0012] In an alternative embodiment, the height difference between the first vertical lining strip and the second vertical lining strip is 0.5 cm - 1.5 cm.
[0013] In an alternative embodiment, pleats are provided at the four corners of the upper layer corresponding to the filling cavities.
[0014] In an alternative embodiment, the width of the pleat is 1 cm - 4 cm.
[0015] In an alternative embodiment, the edge of the upper layer is stitched or connected in a standing height style to the edge of the lower layer, and the standing height is 1 cm - 10 cm.
[0016] In an alternative embodiment, the heat-insulating material includes one or more of grey goose down, grey duck down, white goose down, and white duck down.
[0017] The beneficial effects of the embodiments of the present utility model are as follows:
[0018] 1. An arched bulge is provided at the top of each filling cavity, forming an arched cavity communicating with the lifting cavity. The arched cavity increases the volume of the filling cavity, enabling the duvet to be filled with more down, improving the down filling amount of the duvet, and thus enhancing the heat storage and heat preservation effect of the duvet.
[0019] 2. The arched cavity provides a better unfolding space for the heat-insulating material in the filling cavity. Under the same down filling amount, the down in this application can unfold better compared to the down in the traditional square vertical lining process, thereby storing and fixing more air and forming a heat-insulating layer that effectively prevents heat dissipation, further enhancing the heat storage and heat preservation effect of the entire quilt core.

[0032] At present, the down comforter has become the lightest and warmest comforter filling category in bedding. The down comforter is highly regarded for its excellent warmth retention, lightness, and breathability. The good warmth retention of the down comforter is due to the unique spherical fiber structure of its filling, down. Each filament of down 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. Thus, down forms a natural heat insulation and retention barrier outside the human body that impedes the flow of hot and cold air. Based on this, the warmth retention effect of down is mainly related to the down filling amount and the loft of the down.
[0033] Most of the common styles and processes of down comforters on the market currently are mainly square quilting and through-cut. Both of these processes form a down comforter by quilting down between two layers of fabric. For the through-cut process down comforter, the upper layer of fabric is directly sewn to the lower layer of fabric. The cross-sectional shape of the finished down comforter is flat, which results in a small filling space inside the down comforter, a small down filling amount, and at the same time, the down cannot be effectively stretched inside the flat comforter core, thereby leading to poor warmth retention performance of the finished down comforter. For the square quilting process down comforter, the quilting process down comforter improves the defect of the spatial shape of the through-cut process by adding quilting fabric at the quilting seams of the comforter core, making the cross-sectional shape of the comforter core rectangular. However, in the quilting process, although the filling space inside the down comforter has increased compared to the through-cut process, limited by the cross-sectional shape of the down comforter of the comforter core, the filling space of the down comforter core is also limited.
[0034] In view of the above situation, the present application provides a heat storage and warmth retention down comforter core for increasing the down filling amount of the down comforter core and improving the stretching effect of the down, thereby enhancing the warmth retention effect of the down comforter.
[0035] The following combines the drawings to introduce in detail the basic structure, working principle, and achieved technical effects of the heat storage and warmth retention down comforter core provided by the present application.
[0036] Please refer to Figure 1 and Figure 2 , this embodiment provides a heat storage and warmth retention down comforter core, including a lower layer 110 and an upper layer 120. The lower layer 110 and the upper layer 120 are disposed opposite to each other, and the length and width dimensions of the lower layer 110 correspond to the designed length and width dimensions of the down comforter. The fabric used for the upper layer 120 and the lower layer is one or two of cotton fabric, polyester-cotton fabric, polyester fabric, etc. In this embodiment, the edge of the upper layer 120 and the edge of the lower layer 110 are directly connected by fabric sewing; in other embodiments, the edge of the upper layer 120 and the edge of the lower layer 110 can be connected by a standing height style. According to the different designed dimensions of the down comforter, the height of the standing height is 1 cm - 10 cm. Through the connection and sewing of the lower layer 110 and the upper layer 120, the basic frame structure of the down comforter core is formed.
[0037] Please refer to Figure 1 and Figure 2 , furthermore, the thermal insulation down comforter core further includes a first vertical lining strip 210 and a second vertical lining strip 220. The fabrics used for the first vertical lining strip 210 and the second vertical lining strip 220 are one of polyester fabric, pure cotton fabric, nylon fabric, etc. A plurality of first vertical lining strips 210 are connected between the lower layer 110 and the upper layer 120. The first vertical lining strips 210 are all arranged along the width direction of the lower layer 110, and the plurality of first vertical lining strips 210 are arranged at equal intervals. A plurality of second vertical lining strips 220 are connected between two adjacent first vertical lining strips 210. The two side edges of the second vertical lining strip 220 are respectively connected to the lower layer 110 and the upper layer 120, and the plurality of second vertical lining strips 220 are also arranged at equal intervals.
[0038] Please refer to Figure 2 and Figure 3 , the arrangement of the first vertical lining strip 210 and the second vertical lining strip 220 divides a plurality of rectangular filling cavities 230 between the lower layer 110 and the lower layer 110. The filling cavities 230 are used for filling thermal insulation materials, and the thermal insulation materials include one or more of grey goose down, grey duck down, white goose down, and white duck down. Furthermore, the heights of the first vertical lining strip 210 and the second vertical lining strip 220 are different, so that the upper layer 120 arches at the top of the filling cavity 230, making the top of the filling cavity 230 arched, and an arched cavity 240 communicating with the filling cavity 230 is formed on the filling cavity 230.
[0039] In this embodiment, according to the different design sizes of the down comforter core, the length of the first vertical lining strip 210 is 180 cm - 250 cm, and the height of the first vertical lining strip 210 is 2 cm - 3.5 cm; the length of the second vertical lining strip 220 is 20 cm - 30 cm, and the height of the second vertical lining strip 220 is 0.8 cm - 1.5 cm. The height of the first vertical lining strip 210 is 0.5 cm - 1.5 cm higher than the height of the second vertical lining strip 220, so as to form a plurality of arched cavities 240 corresponding to the filling cavities 230 at the top of the upper layer 120. In other embodiments, it is also possible to set the height of the second vertical lining strip 220 to be 0.5 cm - 1.5 m higher than the height of the first vertical lining strip 210. At this time, arched cavities 240 will also be formed on the upper layer 120 and at the top of each filling cavity 230.
[0040] Compared with the traditional eiderdown quilt, the eiderdown quilt core in the embodiment of the present application is provided with arched bulges on the upper layer 120, forming an arched cavity 240 communicating with the filling cavity 230. The arched cavity 240 expands the volume of the filling cavity 230, thereby improving the filling amount of the eiderdown quilt core. At the same time, when the filling cavity 230 is filled with enough eiderdown, the arched cavity 240 on the upper layer can provide a better unfolding space for the thermal insulation material, so that the fluff filaments of the thermal insulation material can be better unfolded. The fully extended thermal insulation material is used to store and fix more air, and form a thermal insulation layer that effectively prevents heat dissipation, thereby improving the heat storage and insulation effect of the entire quilt core.
[0041] In order to facilitate the processing of multiple arched bulges on the upper layer 120, pleats are processed at the four corners of the upper layer 120 and located at the filling cavity 230. The pleating method of each pleat is a single-sided pleat, and the pleating width is 1 cm - 4 cm, that is, the upper layer 120 above the four corners of the filling cavity 230 is folded upward by 1 cm - 4 cm. By processing multiple pleats on the upper layer 120, multiple arched cavities 240 are formed on the upper layer 120. Further, due to the pleats processed on the upper layer 120, the fabric used for the upper layer 120 in the embodiment of the present application is 105% - 150% of the fabric used in the normal upright lining process or the cut-through process, and the extra fabric is used for the pleating part necessary for the pleating process.
[0042] When the current square upright lining process eiderdown quilt is filled with eiderdown, generally, holes are opened along the length direction of the eiderdown quilt on the upright lining, and the filling tube is inserted into the eiderdown quilt through the holes, and the filling tube is gradually withdrawn as the filling progresses, and then the eiderdown is introduced into multiple squares of the eiderdown quilt. However, due to the holes opened along the length direction of the eiderdown quilt on the upright lining, during the use of the eiderdown quilt, the eiderdown is likely to move between the squares along the length direction of the eiderdown quilt, thereby affecting the thermal insulation performance of the eiderdown quilt.
[0043] Based on this, please refer to Figure 1 and Figure 3 , the second upright lining strip 220 is arranged in a staggered manner on both sides of the same first upright lining strip 210, that is, the filling cavities 230 located on both sides of the same first upright lining strip 210 are arranged in a staggered manner. In the embodiment of the present application, the filling cavities 230 are arranged in a staggered manner on both sides of the first upright lining strip 210. When the eiderdown quilt is filled with eiderdown, only through holes can be opened on multiple second upright lining strips 220, and the filling tube is inserted into the eiderdown quilt along the width direction of the eiderdown quilt for filling during filling. Since the first upright lining strip 210 is complete in this embodiment, and the filling cavities 230 are distributed in a staggered manner on both sides of the first upright lining strip 210, the down fibers cannot move along the length direction of the eiderdown quilt, improving the defect that the down fibers are likely to move during the daily use of the eiderdown quilt.
[0044] The working principle of the heat storage and thermal insulation down comforter core is as follows: An arched bulge is provided at the top of each square filling cavity 230 to form an arched cavity 240 communicating with the filling cavity 230. The arched cavity 240 increases the volume of the filling cavity 230, which is used to increase the amount of down filled in the comforter. At the same time, under the condition of the same amount of down filled, the upper arched cavity 240 in this application can provide a better unfolding space for the thermal insulation material, so that the fluff filaments of the thermal insulation material can be better unfolded to store and fix more air, and form a thermal insulation layer that effectively prevents heat dissipation, thereby improving the heat storage and thermal insulation effect of the entire comforter core.
[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
