Description

Technical Field

[0001] This utility model relates to the field of bedding technology, and in particular to a heat-storing and temperature-locking down comforter structure. Background Technology

[0002] Down comforters hold an important place among winter thermal products due to their lightweight, warmth, and breathability. As a natural animal protein fiber, down's unique spherical structure and densely packed tiny pores give it excellent heat retention properties, effectively absorbing heat emitted by the body and insulating against the intrusion of cold air, thus providing a comfortable sleeping environment.

[0003] However, existing down comforters still have many shortcomings in their structural design, seriously affecting their heat retention and user experience. Specifically, traditional down comforters mostly use a flat-seam construction, which limits the natural fluffiness of the down clusters, resulting in a limited air layer thickness inside the comforter and making it difficult to form a stable and efficient static air insulation layer. In actual use, due to the movement of the body during sleep, especially in the head and foot areas, frequent body movements cause airflow disturbances inside the comforter, disrupting the stability of the local temperature field and making it easy for heat to dissipate, significantly reducing the warmth retention effect. In addition, existing down comforters usually lack an effective three-dimensional support structure on the sides, making them prone to sagging during use. This not only affects the overall aesthetics and comfort of the comforter, but more importantly, the sagging sides create channels for cold air to penetrate, further exacerbating heat loss and reducing the overall warmth retention performance of the down comforter. These structural defects make existing down comforters perform poorly in providing a continuous and stable warmth effect, failing to fully utilize the excellent heat retention properties of down itself. To address these issues, existing technologies urgently need improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat-storing and temperature-locking down comforter structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a heat-storing and temperature-locking down comforter structure, comprising:

[0006] The duvet cover defines the internal space used to fill the down.

[0007] The pleated areas are located at the head and tail of the quilt cover;

[0008] The quilt side is provided on both sides of the quilt surface, and the lower surface of the quilt side is provided with a raised support area;

[0009] Multiple partitions are installed in the interior space of the quilt, and the multiple partitions divide the interior space into multiple units.

[0010] This technical solution provides a basic down comforter structure. By introducing pleated areas, raised support areas on the sides, and internal mesh, it effectively improves the loft of the down, prevents heat loss, and provides side support, thereby achieving excellent heat storage and temperature retention effects.

[0011] Furthermore, the folded area has an elastic shrinkage ratio of 3:1 to 5:1 and forms a continuous wavy fold structure.

[0012] This technical solution ensures that the folded areas have appropriate elasticity and deformation capacity at the head and tail of the quilt, effectively adapting to human movement, maintaining a stable air layer, and further enhancing the warmth retention effect.

[0013] More specifically, the side is a hollow body, and the raised support area is a filling material located inside the side.

[0014] This technical solution provides lightweight and effective three-dimensional support for the sides of down comforters, preventing them from collapsing, while the filling effectively isolates cold air penetration, improving overall warmth retention.

[0015] Preferably, the wavelength of the wavy pleated structure is 15mm to 25mm and the wave height is 8mm to 12mm.

[0016] This technical solution allows for precise control of the shape of the wavy pleats, maximizing the loft of the down while providing comfort, thus forming a highly efficient static air insulation layer.

[0017] In some implementations, the side is made of a down-proof, high-count fabric.

[0018] This technical solution effectively prevents down from escaping from the sides of the comforter, maintains the integrity and uniform distribution of down inside the comforter, extends the product's lifespan, and preserves its warmth.

[0019] Furthermore, the quilt cover includes an upper fabric and a lower fabric, with the internal space defined between the upper fabric and the lower fabric.

[0020] This technical solution clearly defines the down filling area, ensuring the structural stability of the down comforter and the effective storage of the down.

[0021] Preferably, multiple meshes are connected between the upper fabric and the lower fabric.

[0022] This technical solution ensures the fixation and stability of the insulation net inside the quilt, effectively preventing down displacement and accumulation, and maintaining the independent insulation effect of each unit.

[0023] In some implementations, the surface is a rectangular structure.

[0024] This technical solution provides a quilt shape that conforms to conventional usage habits and production standards, making it easy to manufacture and use in daily life.

[0025] More specifically, the pleated area is located on two opposite sides of the quilt cover, and the quilt side is located on the other two opposite sides of the quilt cover.

[0026] This technical solution allows for the rational arrangement of folded areas and sides of the quilt, enabling them to provide optimal warmth and support on a rectangular quilt body, covering areas prone to heat loss and collapse.

[0027] Furthermore, multiple meshes divide the interior space into multiple three-dimensional box-shaped units.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The heat-storing and temperature-locking down comforter structure disclosed in this utility model addresses the problems of limited loft, easy heat loss, and insufficient side support in existing down comforters. Through innovative structural design, it significantly improves the heat-storing and temperature-locking effect and user experience of down comforters.

[0030] Specifically, existing down comforters mostly use a flat-seam construction, which restricts the natural lofting space of the down clusters, resulting in a limited thickness of the internal air layer and making it difficult to form a stable and efficient static air insulation layer. This invention, by setting multiple mesh panels inside the comforter surface, divides the internal space into multiple independent units, effectively restricting the movement and accumulation of down. This allows the down clusters to fully loft, forming a stable and thick static air insulation layer, thereby significantly improving the overall warmth retention of the down comforter.

[0031] Furthermore, to address the issues of airflow disturbance and heat loss within the quilt caused by human activity during sleep, this invention incorporates pleated areas at the head and foot of the quilt. These pleated areas adapt to body movement and, through their structural characteristics, effectively buffer and absorb internal airflow disturbances, maintaining the stability of the local temperature field, thereby reducing heat loss and ensuring continuous warmth inside the quilt.

[0032] Furthermore, existing down comforters typically lack effective three-dimensional support structures on their sides, making them prone to collapse and creating channels for cold air to penetrate. This invention provides side panels on both sides of the comforter surface, with raised support areas on the lower surface of these side panels. These raised support areas provide solid three-dimensional support for the comforter sides, effectively preventing collapse. This not only maintains the comforter's aesthetics and comfort but, more importantly, effectively blocks the intrusion of external cold air, eliminating channels for cold air penetration and further locking in heat within the comforter, significantly improving the overall heat storage and temperature retention capacity of the down comforter.

[0033] In summary, this utility model overcomes the defects of existing down comforters through multiple structural optimizations, such as the internal mesh of the comforter cover, the pleated areas at the head and tail of the comforter, and the raised support areas on the sides. It achieves maximum down loft, stabilizes the internal temperature field, and effectively isolates external cold air, thus providing a down comforter structure with better heat storage and temperature locking effect and a more comfortable user experience.

[0038] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0039] Existing traditional down comforters, due to the conventional flat-seam filling process, compress the naturally fluffy space of the down clusters, resulting in a limited air layer thickness and difficulty in forming a stable static air insulation layer. Frequent human activity at the head and foot of the comforter generates airflow disturbances, disrupting the stability of the local temperature field. Furthermore, conventional comforters lack a three-dimensional support structure on the sides, making them prone to collapse during use, thus creating channels for cold air penetration and severely impacting the comforter's warmth and comfort. For example, in cold winters, when a user uses a traditional down comforter, the unstable internal air layer and the airflow generated by movement at the head, foot, and sides cause rapid heat loss, often leaving the user feeling localized areas lack warmth or even experiencing a cold draft. This significantly reduces the comforter's heat retention and insulation capabilities. To address these issues, this application proposes a heat-retaining and heat-locking down comforter structure, aiming to effectively solve the problems of insufficient warmth retention and easy heat loss in existing down comforters. This structure, through the arrangement of the comforter surface 1, pleated area 2, comforter side 3, raised support area 4, and multiple meshes 6, works synergistically to optimize the internal structure and edge support of the down comforter, thereby significantly improving its heat storage and temperature retention effect.

[0040] like Figures 1 to 3 The heat-storing and temperature-locking structure of a down comforter shown includes:

[0041] 1. The 1.0 surface defines the internal space for filling with down.

[0042] The pleated area 2 is set in the head and tail areas of the quilt cover 1;

[0043] The side 3 is provided on both sides of the quilt surface 1, and the lower surface of the side 3 is provided with a raised support area 4.

[0044] Multiple partitions 6 are set in the internal space of the cover 1, and the multiple partitions 6 divide the internal space into multiple units.

[0045] The heat-storing and temperature-locking down comforter structure of this application solves the problems of existing technologies by having its components work synergistically to form a highly efficient warmth-preserving system. Specifically, the comforter surface 1, as the main body of the down comforter, contains the down and is the foundation for warmth preservation. When a user covers themselves with the down comforter, the heat emitted by the body is absorbed and stored by the down layer. However, traditional down comforters are prone to gaps and airflow in the head and foot areas due to user movement. This application addresses this by setting pleated areas 2 in the head and foot areas of the comforter surface 1, allowing these areas to better conform to the user's body curves, reducing gaps between the comforter and the body, thereby effectively reducing air convection speed. This creates a "Venturi effect" area, making it difficult for heat to dissipate and improving the warmth preservation effect in local areas. At the same time, the raised support area 4 set on the sides 3 and the lower surface of the comforter plays a key role in solving the problem of cold air penetration. The sides of traditional down comforters are usually relatively flat, making it difficult to effectively block cold air. The raised support area 4 of this application increases the edge thickness of the comforter side 3, forming a three-dimensional enclosure structure. When the edge of the comforter contacts the user's body or mattress, this raised support area 4 forms an effective "warm room barrier," blocking cold air from entering the comforter and significantly improving the warmth retention of the comforter edge. Furthermore, the multiple meshes 6 within the comforter surface 1 are crucial for maintaining the even distribution of down and reducing internal airflow. The warmth retention of a down comforter largely depends on the loft and uniformity of the down. Without the meshes 6, the down easily moves and accumulates within the internal space, resulting in sparse down in some areas and reduced warmth. By dividing the internal space into multiple units with the meshes 6, the down comforter is confined within its respective units, ensuring even distribution of down even when the user turns over or shakes the comforter, guaranteeing consistent warmth retention throughout the entire comforter. More importantly, these meshes 6 effectively restrict air convection inside the down comforter, reducing heat loss through airflow and thus further enhancing the down comforter's heat retention and temperature locking capabilities. In summary, the down comforter structure of this application, through the ingenious combination and synergistic effect of the comforter surface 1, the pleated area 2, the comforter sides 3, the raised support area 4, and multiple meshes 6, addresses the shortcomings of existing down comforters in terms of warmth, structural stability, and comfort from multiple dimensions, achieving superior heat retention and temperature locking effects and providing users with a warmer and more comfortable sleep experience.

[0046] As one embodiment of this utility model, the pleated area 2 has an elastic shrinkage ratio of 3:1 to 5:1 and forms a continuous wavy pleated structure.

[0047] The elastic contraction ratio of the pleated area 2 refers to the ratio of its length in a fully stretched state to its length in a naturally contracted state, and this ratio is set to 3:1 to 5:1. Specifically, when the pleated area 2 is stretched, its length can reach 3 to 5 times its natural length. This design aims to ensure that the pleated area 2 can fully stretch to adapt to different head or foot postures when used, while effectively contracting when relaxed to form a close fit. Furthermore, the pleated area 2 is designed to form a continuous wavy pleated structure. This wavy structure is not a simple fold, but rather a smooth, continuous curved shape that provides a uniform elastic distribution and helps to form tiny air cavities within the pleats, further enhancing insulation performance.

[0048] This application's solution effectively solves the problems of insufficient fit and heat loss that may exist in traditional pleated areas by designing the pleated area 2 with a specific elastic shrinkage ratio of 3:1 to 5:1 and forming a continuous wavy pleated structure. Specifically, when the user lies down, the pleated area 2 can adaptively expand and contract according to the shape and posture of the head or feet. Its high elastic shrinkage ratio ensures that the comforter can tightly wrap these areas, eliminating or significantly reducing gaps between the comforter and the body. At the same time, the continuous wavy pleated structure not only provides a soft fit but also forms multiple tiny air layers inside the pleats. These air layers can effectively block heat conduction, thereby significantly improving the heat storage and heat retention capacity of the down comforter and preventing heat loss from the head and foot areas.

[0049] In one embodiment of this utility model, the side 3 is a hollow body, and the raised support area 4 is a filling material disposed inside the side 3.

[0050] The solution proposed in this application effectively solves the problems of insufficient stability and easy displacement of the raised support area 4 by designing the quilt side 3 as a hollow structure and using the raised support area 4 as its internal filling material. Because the raised support area 4 is firmly housed within the internal space of the quilt side 3, its shape and position remain stable, ensuring that the quilt can continuously provide uniform and reliable raised support during use, avoiding a decrease in comfort or poor support effect caused by the displacement of the support.

[0051] As one embodiment of this utility model, the wavelength of the wave-shaped pleated structure is 15mm to 25mm, and the wave height is 8mm to 12mm.

[0052] This application's solution, by limiting the wavelength and wave height of the wavy pleated structure, enables the pleated area 2 to more effectively capture and store heat emitted by the human body. When the wavelength is too short, the pleats become too dense, which reduces airflow and affects heat storage; when the wavelength is too long, the number of pleats decreases, and the heat storage capacity also declines. Similarly, when the wave height is too low, the increase in surface area provided by the pleats is limited, and the heat storage effect is not obvious; when the wave height is too high, the pleats become stiff, affecting the feel and comfort of the down comforter. Therefore, this application achieves the optimal balance between heat storage effect and comfort by limiting the wavelength to the range of 15mm to 25mm and the wave height to the range of 8mm to 12mm.

[0053] As one embodiment of this utility model, the side 3 is made of down-proof high-count fabric 5.

[0054] Among them, the down-proof high-count fabric 5 refers to a textile fabric with high density and high thread count. This type of fabric typically has excellent down-proof properties and can effectively prevent down from escaping from the side 3 of the comforter. Specifically, the down-proof high-count fabric 5 can achieve this through the following methods:

[0055] Use high-count yarn: Use fine and dense yarn to increase the fabric's tightness and reduce the gaps that allow down to penetrate.

[0056] Special weaving techniques: Employing special weaving processes, such as jacquard weaving or satin weaving, further enhances the down-proof properties of the fabric.

[0057] Apply a coating: Apply a down-proof coating to the fabric surface to form a physical barrier and prevent down from penetrating.

[0058] The solution proposed in this application, by using a high-count down-proof fabric 5 to fabricate the side 3 of the comforter, effectively solves the problem of down feathers escaping from the side 3, ensuring the cleanliness and comfort of the down comforter. Because the high-count down-proof fabric 5 has a high density and tight structure, it effectively prevents down feathers from penetrating the fabric, thus preventing them from escaping from the side 3.

[0059] As one embodiment of this utility model, the quilt cover 1 includes an upper fabric and a lower fabric, and the internal space is defined between the upper fabric and the lower fabric.

[0060] The top and bottom layers can be made of different materials and using different processes. For example, the top layer can be made of a soft, skin-friendly material, while the bottom layer can be made of a down-proof material, thus comprehensively improving the quality of the down comforter. Specifically, the top layer can be made of high-count cotton, silk, or other materials to provide a comfortable feel; the bottom layer can be made of high-density down-proof fabric to prevent down from penetrating.

[0061] The solution proposed in this application is effective in preventing down penetration because the double-layer fabric structure adds a physical barrier. Even if a small amount of down penetrates one layer of fabric, it will be blocked by the other layer, thus preventing the down from directly exiting the comforter surface. It is precisely because of this dual protection mechanism that down comforters have better down-proof performance and a longer service life.

[0062] The above technical solutions effectively address the issue of down penetration in single-layer comforters, improving their quality and lifespan. Furthermore, by selecting different fabric materials, the comfort and functionality of down comforters can be further enhanced to meet the needs of diverse consumers.

[0063] In one embodiment of this utility model, multiple meshes 6 are connected between the upper and lower fabric layers.

[0064] The function of the mesh 6 is to separate and secure the down, preventing uneven distribution within the internal space. In a preferred embodiment, the mesh 6 can be connected between the upper and lower fabrics by heat fusion or sewing to form a robust connection structure. Furthermore, the mesh size of the mesh 6 can be adjusted according to actual needs to accommodate different types of down and varying fill densities.

[0065] The solution proposed in this application connects the upper and lower fabric layers using multiple meshes 6, effectively solving the problem of uneven down distribution. Specifically, the meshes 6 divide the internal space into multiple independent units, restricting the free movement of the down and ensuring its even distribution within each unit. This prevents down from piling up at the head or foot of the comforter or creating gaps at the edges, thereby improving the overall warmth retention.

[0066] In one embodiment of this utility model, the outer surface 1 is a rectangular structure.

[0067] In one embodiment of this utility model, the pleated area 2 is provided on two opposite sides of the quilt surface 1, and the quilt side 3 is provided on the other two opposite sides of the quilt surface 1.

[0068] As one embodiment of this utility model, multiple partitions 6 divide the internal space into multiple three-dimensional box-shaped units.

[0069] The three-dimensional box-shaped unit refers to a three-dimensional space with a certain height and depth, which can better accommodate and fix the down feathers, preventing them from shifting and clumping. Specifically, these box-shaped units can be implemented in various ways, such as by setting the mesh 6 as a three-dimensional structure with a certain height, or by adding connectors between the meshes 6.

[0070] The solution proposed in this application divides the internal space into multiple three-dimensional box-shaped units, allowing the down to be distributed more evenly within the interior space of the duvet cover 1. Since each box-shaped unit has a certain amount of space, the down will not easily shift or clump together, thus ensuring the overall warmth performance of the duvet cover 1. Furthermore, the three-dimensional box-shaped units also increase the loft of the duvet cover 1, improving sleep comfort.

[0071] The above technical solution effectively prevents down from shifting and gathering, ensuring the overall warmth of the duvet cover 1 and improving sleep comfort. Compared with traditional planar partitioning methods, the three-dimensional box-shaped unit structure of this application can better fix the down, making it less susceptible to displacement due to external forces, thereby ensuring the long-term performance of the duvet cover 1.

[0072] Working principle of this utility model:

[0073] The comforter cover 1, as the main body of the down comforter, contains down and is the foundation for warmth. When a user covers themselves with the comforter, the heat emitted by the body is absorbed and stored by the down layer. However, traditional down comforters are prone to gaps and airflow in the head and foot areas due to user movement. This application addresses this by creating pleated areas 2 in the head and foot areas of the comforter cover 1, allowing these areas to better conform to the user's body curves, reducing gaps between the comforter and the body, and effectively reducing air convection speed. This creates a "Venturi effect" zone, making it less likely for heat to dissipate and improving the warmth of the local area. Simultaneously, the raised support area 4 on the sides 3 and its underside plays a crucial role in solving the problem of cold air penetration. The sides of traditional down comforters are usually relatively flat, making it difficult to effectively block cold air. The raised support area 4 in this application increases the edge thickness of the sides 3, forming a three-dimensional enclosure structure. When the edge of the comforter comes into contact with the user's body or mattress, this raised support area 4 forms an effective "warm room barrier," blocking cold air from entering the comforter and significantly improving its warmth. Furthermore, the multiple meshes 6 within the comforter surface 1 are crucial for maintaining the even distribution of down and reducing internal airflow. The warmth of a down comforter largely depends on the loft and uniformity of the down. Without the meshes 6, the down easily moves and accumulates within the comforter, resulting in sparse down in some areas and reduced warmth. By dividing the internal space into multiple units with the meshes 6, the down is confined within each unit, ensuring even distribution evenly even when the user turns over or shakes the comforter, guaranteeing consistent warmth throughout the entire comforter. More importantly, these meshes 6 effectively restrict air convection within the comforter, reducing heat loss through airflow and further enhancing its heat retention capacity. In summary, the down comforter structure of this application, through the ingenious combination and synergistic effect of the comforter surface 1, the pleated area 2, the comforter side 3, the raised support area 4, and multiple meshes 6, solves the shortcomings of existing down comforters in terms of warmth retention, structural stability, and comfort from multiple dimensions, achieving a better heat storage and temperature locking effect, and providing users with a warmer and more comfortable sleep experience.
