[0040] In one embodiment of the present invention, Figure 1-8As shown, a spring mattress with a double-layer spring combination includes an anti-tear layer 1, an antibacterial layer 2, an elastic thermal insulation layer 3, a flexible support layer 4, a dynamic support layer 5, a reinforcement layer 6, a buffer layer 7, a main support layer 8, a filling layer 9, a transition layer 10, a dustproof layer 11, a breathable layer 12 and a connecting component; the anti-tear layer 1, the antibacterial layer 2, the elastic thermal insulation layer 3, the elastic support layer 4, the dynamic support layer 5, the reinforcement layer 6, the buffer layer 7, the main support layer 8, the filling layer 9, the transition layer 10, the dustproof layer 11 and the breathable layer 12 are arranged in order from top to bottom; the connecting component The connecting assembly is used to connect the anti-tear layer 1, the antibacterial layer 2, the elastic thermal insulation layer 3, the elastic support layer 4, the dynamic support layer 5, the reinforcement layer 6, the buffer layer 7, the main support layer 8, the filling layer 9, the transition layer 10, the dustproof layer 11 and the breathable layer 12; the main support layer 8 includes an elastic fitting layer 81 and an elastic support layer 82; the elastic fitting layer 81 is installed on the top of the elastic support layer 82, the elastic fitting layer 81 is used to fit the physiological curve of the human body, and the elastic support layer 82 is used to ensure the elasticity of the mattress and prevent the mattress from sinking.In this embodiment, the tear-proof layer 1, the antibacterial layer 2, the elastic thermal insulation layer 3, the elastic support layer 4, the dynamic support layer 5, the reinforcement layer 6, the buffer layer 7, the main support layer 8, the filling layer 9, the transition layer 10, the dustproof layer 11 and the breathable layer 12 are arranged in sequence from top to bottom and connected with the connecting assembly without the need for glue connection, thereby achieving the purpose of environmentally friendly connection. Furthermore, the main support layer 8 is divided into an upper elastic fitting layer 81, which is designed with different elasticities according to the body curve of the human body, so that it conforms to the physiological curve of the human body and improves sleep quality. The support layer 82 is the core support layer, which plays the main supporting role. High-elastic springs are used to prevent the mattress from sinking and collapsing. Specifically, the tear-resistant layer 1 has sufficient tearing strength to avoid seams or tearing damage. The antibacterial layer 2 can inhibit the breeding of bacteria and mites, and provide preliminary moisture absorption and buffering. The elastic thermal insulation layer 3 realizes elastic support and temperature and humidity regulation to achieve warmth and constant temperature. The flexible support layer 4 provides the mattress with a buffering function with both soft touch and support. The dynamic support layer 5 dynamically adjusts the support force according to body movements, and reduces resistance by 50% when turning over, reducing sleep interruptions; for the waist, knees and other parts that are easily suspended The invention relates to a mattress which is a mattress that has been layed on the ground for a long time and has a plurality of layers of mattress cover, wherein the mattress cover is provided with ... , dynamic support layer 5, reinforcement layer 6, buffer layer 7, main support layer 8, elastic fitting layer 81, elastic support layer 82, filling layer 9, transition layer 10, dustproof layer 11, breathable layer 12 and connecting components, to achieve glue-free and environmentally friendly production, less odor, and through the three-dimensional structure design of anti-slip surface, multi-layer buffering, core support and bottom layer breathable, it achieves multi-layer functional coordination, which is conducive to improving the comfort of product use, and adopts a double-layer elastic structure, which not only enables the mattress to fit the physiological curve of the human body, but also ensures the mattress's anti-deformation ability, so that the mattress has both wrapping feeling and support, and prevents the single elastic structure from causing the mattress to be too hard or too soft.

[0041] like Figure 1-4As shown, the main support layer 8 also includes an isolation layer 83, and the isolation layer 83 is arranged between the elastic bonding layer 81 and the elastic support layer 83; the elastic bonding layer 81 includes a first elastic component 811, and the first elastic component 811 is a four-leaf clover-shaped structure. A plurality of first elastic components 811 are evenly arranged in an array along a rectangular structure, and adjacent two elastic components 811 are connected to each other; the first elastic component 811 includes four first elastic members 812 and four first cloth bags, and the periphery of each first elastic member 812 is The first cloth bags are respectively provided, and the ends of the four first elastic members 812 are respectively connected to each other through the corresponding first cloth bags; the elastic bonding layer 81 is provided with a head and neck area 813, a shoulder area 814, a waist area 815, a hip area 816 and a leg area 817 in sequence along its length direction; the elastic compression amount of the head and neck area 813, the elastic compression amount of the shoulder area 814, the elastic compression amount of the leg area 817, the elastic compression amount of the waist area 815 and the elastic compression amount of the hip area 816 decrease gradually in sequence.In this embodiment, the first elastic member 812 is a spring of leaf-shaped structure, and each of the first elastic components 811 is composed of four first elastic members 812 and four first cloth bags. The four cloth bags are respectively sleeved on the outer periphery of the corresponding first elastic member 812, and then the ends of the four first elastic members 812 are sequentially connected along the circumferential direction to form a first elastic component 811 with a four-leaf clover shape structure. The two adjacent first elastic components 811 are connected by the first cloth bags on the outer periphery of the two first elastic members 812. Specifically, the two first cloth bags can be connected by ultrasonic stitching along the stitching, or the two cloth bags can be connected by melting. It should be noted that the melting method is used. The connection bag is a thermoplastic plastic bag, and a plurality of first elastic components 811 in a four-leaf clover shape are evenly arrayed along a rectangular structure and connected to each other, which is beneficial to improving the structural stability of the elastic bonding layer 81. The isolation layer 83 is arranged between the elastic bonding layer 81 and the elastic support layer 83, so that the elastic bonding layer 81 can be placed stably. The isolation layer 83 is made of soft sponge. Furthermore, along the length direction of the mattress, that is, from the head to the foot of the bed, a head and neck area 813, a shoulder area 814, a waist area 815, a hip area 816 and a leg area 817 are respectively provided. The compression amount of the first elastic member 812 corresponding to different areas is different. Specifically, the head and neck area 8 The spring compression of 13 is the largest, the head is light, the natural lordosis of the cervical spine is small, and soft and fitting support is required. It is easy to deform when under the pressure of the head weight, and the compression can reach 3-5cm. The head is wrapped by large deformation to avoid compressing the cervical spine. The spring compression of the shoulder area 814 is second, the shoulder width is large, the muscles are thicker, and the support and shoulder sinking requirements need to be balanced. The spring stiffness is slightly higher than that of the head and neck area, and the compression is about 2-3cm, which can make the shoulders sink moderately and support the upper back curve to prevent scoliosis. The spring compression of the leg area 817 is medium, the leg weight is medium, and the knees need soft support when they bend naturally to avoid leg muscle tension. The compression is about 1.5-2.5cm, which adapts to the leg curve. The weight of the calves and thighs is distributed to maintain a natural knee flexion angle. The spring compression amount of the waist area 815 is relatively small, and the lumbar lordosis curvature is large. It is necessary to resist the weight of the upper body to prevent the waist from being suspended in the air and causing lumbar muscle strain. The compression amount is about 1-2cm, and rigid support is provided through small deformation to maintain the physiological curvature of the lumbar spine and avoid excessive sinking. The spring compression amount of the hip area 816 is the smallest. The hip is the load-bearing core of the human body, and the bones are protruding, so strong support is required to disperse the pressure. The compression amount is ≤1cm, and the ischial tuberosity is supported with high hardness to prevent the hip from sinking too much and causing spinal deformation, while avoiding pelvic tilt. The above design can make the elastic fitting layer 81 conform to the physiological curve of the human body, ensure healthy sleep, and improve sleep quality.

[0042] like Figure 1-6As shown, the elastic support layer 82 includes a second elastic component 821 and a connecting strip 823. The second elastic component 821 is a four-leaf clover-shaped structure. Multiple second elastic components 821 are evenly arrayed along the rectangular structure. Two adjacent elastic components 821 are connected to each other. The multiple second elastic components 821 on the outermost periphery of the same side are connected by the connecting strip 823; the second elastic component 821 includes four second elastic members 822 and four second cloth bags. The outer periphery of each second elastic member 822 is respectively covered with the second cloth bag, and the ends of the four second elastic members 822 are respectively connected to each other through the corresponding second cloth bags. In this embodiment, the number of the connecting strips 823 is eight, and the four sides of the elastic supporting layer 82 are connected by the connecting strips 823 respectively. Specifically, the tops of the multiple second elastic components 821 on the outermost periphery are connected by four connecting strips 823, and the bottoms of the multiple second elastic components 821 on the outermost periphery are connected by four connecting strips 823. The second cloth bag on the outermost periphery is sewn with corresponding mounting holes to facilitate the passage of the connecting strips 823. Finally, the connecting strips 823 are welded together from head to tail. The connecting strips 104 play a reinforcing role and make the main supporting layer 10 more integrated. The second elastic member 822 is a spring with a leaf-shaped structure. Each of the second elastic components 821 is composed of four second elastic members 822 and four second cloth bags. The four cloth bags are respectively sleeved on the outer periphery of the corresponding second elastic member 822, and then the ends of the four second elastic members 822 are connected in sequence along the circumferential direction to form a second elastic component 821 with a four-leaf clover shape structure. The two adjacent second elastic components 821 are connected by the second cloth bags on the outer periphery of the two second elastic members 822. Specifically, the two second cloth bags can be connected by ultrasonic stitching along the stitching, and the two cloth bags can also be connected by melting. It should be noted that the cloth bag using the melting connection method is a thermoplastic plastic cloth bag, and multiple second elastic components 821 with a four-leaf clover shape structure are evenly arrayed along the rectangular structure and connected to each other, which is beneficial to improving the structural stability of the elastic support layer 82.

[0043] like Figure 1-2As shown, the connection assembly includes a first connector 131; the tear-proof layer 1, the antibacterial layer 2, the elastic thermal insulation layer 3, the flexible support layer 4, the dynamic support layer 5, the reinforcement layer 6, the buffer layer 7, the main support layer 8, the filling layer 9, the transition layer 10, the dust-proof layer 11 and the breathable layer 12 are connected by the first connector 131. In this embodiment, the first connector 131 is an I-shaped structure, such as the I-shaped connector of a clothing tag. When connecting the upper and lower adjacent layers, after placing the dust-proof layer 11 on top of the breathable layer 12, a needle gun is used to drive the bottom end of the first connector 131 from the top of the dust-proof layer 11 and through the dust-proof layer 11 and the breathable layer 12, so that the bottom end of the first connector 131 passes through the bottom of the breathable layer 12, thereby achieving the connection between the dust-proof layer 11 and the breathable layer 12, and so on. Then, the transition layer 10 is placed The top of the dust-proof layer 11 is then connected to the transition layer 10 and the dust-proof layer 11 by using a needle gun, and the first connecting piece 131 is then driven in to connect the transition layer 10 and the dust-proof layer 11 until the multi-layer structure of the mattress is completely connected. Specifically, two adjacent layers are connected using a corresponding number of first connecting pieces 131 according to process requirements and connection stability. For example, the dust-proof layer 11 and the breathable layer 12 are connected using multiple first connecting pieces 131 to ensure the stability of the connection. Similarly, the transition layer 10 and the dust-proof layer 11 are also connected using the same number of first connecting pieces 131.

[0044] like Figure 8 As shown, the connection assembly includes a third connection member 133, one end of the third connection member 133 is installed on the top of the anti-tear layer 1, and the other end of the third connection member 133 passes through the anti-tear layer 1, the antibacterial layer 2, the elastic thermal insulation layer 3, the flexible support layer 4, the dynamic support layer 5, the reinforcement layer 6, the buffer layer 7, the main support layer 8, the filling layer 9, the transition layer 10, the dustproof layer 11 and the breathable layer 12 in sequence, and is installed at the bottom of the breathable layer 12. Specifically, the third connection member 133 is a rope, and the number of the third connection members 133 is as follows: According to the process settings, during installation, one end of the third connecting piece 133 is installed on the top of the anti-tear layer 1, and a knot is tied at the top of the third connecting piece 133, so that it cannot fall out from the top of the anti-tear layer 1, and the other end of the third connecting piece 133 passes through the anti-tear layer 1, antibacterial layer 2, elastic thermal insulation layer 3, flexible support layer 4, dynamic support layer 5, reinforcement layer 6, buffer layer 7, main support layer 8, filling layer 9, transition layer 10, dustproof layer 11 and breathable layer 12 in sequence, and is installed at the bottom of the breathable layer 12, and a knot is tied at the bottom end of the third connecting piece 133, so that it cannot fall out from the bottom of the breathable layer 12.

[0045] like Figure 1-2 and Figure 7As shown, the tear-proof layer 1 includes a woven bottom layer 11, an intermediate layer 12 and a surface layer 13, wherein the intermediate layer 12 is located between the bottom layer 11 and the surface layer 13; the bottom layer 11 adopts the same weft yarn thickness, and the surface layer 13 adopts an increased weft yarn thickness, the portion where the surface layer is separated from the bottom layer forms a raised area 14, and the area where the surface layer and the bottom layer are interwoven forms a non-raised area 15; the intermediate layer 12 adopts polyester high-elastic yarn; the weft yarn used in the surface layer 13 is thicker than the weft yarn used in the bottom layer 11, and the thickness ratio is 3:1, and the weft yarn used in the intermediate layer 12 is thicker than the weft yarn used in the bottom layer 11, and the thickness ratio is greater than 10:1. In this embodiment, the middle layer 12 is located between the bottom layer 11 and the surface layer 13, and the surface layer 13 is located at the top layer of the fabric. There are two structures between the surface layer 13, the middle layer 12 and the bottom layer 11, namely, separation and interweaving. The separation part is a layered structure and a raised area 14 is formed on the surface of the fabric. The interweaving part is a single-layer structure and a non-raised area 15 is formed on the surface of the fabric. The surface layer, the middle layer and the bottom layer are woven into an integral structure at the non-raised area 15. The surface layer warp and the bottom layer warp at the boundary of the raised area 14 are merged into a warp, wherein the surface layer weft is below the warp, and the bottom layer weft is above the warp. The bottom layer weft and the surface layer weft clamp the warp above and below. The weft of the surface layer in the raised area 14 is added with reinforcing wire side by side. In the weft of the surface layer in the raised area 14, the reinforcing wire and the surface layer weft are kept in parallel, the middle layer weft is independent, and the bottom layer weft is independent The fabric forms a three-layer structure of a surface layer, a middle layer and a bottom layer at the corresponding raised area 14, and the fabric forms a surface layer, a middle layer and a bottom layer at the corresponding non-raised area 15, which are woven into an integrated structure. The bottom layer adopts the same weft yarn thickness, and the surface layer adopts an increased weft yarn thickness. The weft yarn used in the surface layer and the weft yarn used in the bottom layer are 3:1 in thickness ratio. The weft yarn used in the middle layer is thicker than the weft yarn used in the bottom layer, and the thickness ratio is greater than 10:1. Specifically, the weft yarn used in the bottom layer is 150D, the weft yarn used in the surface layer is 300D, and the weft yarn used in the middle layer is 1800D. The weft yarn of the surface layer and the weft yarn of the bottom layer are the same yarn, and the weft yarn of the middle layer 12 is made of polyester high elastic yarn. The surface layer warp yarn at the boundary of the raised area 14 and the bottom layer warp yarn are merged into a warp yarn, wherein the surface layer weft yarn is below the warp yarn, and the bottom layer weft yarn is above the warp yarn, and the bottom layer weft yarn and the surface layer weft yarn clamp the warp yarn above and below. Preferably, the non-raised area 15 of the fabric includes a dense weft area and a sparse weft area. The wefts in the dense weft area are closely arranged side by side and woven with the warp threads into a plain stitch structure. The sparse weft area is a grid structure. The adjacent multiple weft threads in the sparse weft area are put together into one strand and woven with the warp threads into a plain stitch structure.In this embodiment, the tear-proof layer 1 separates the surface layer, the middle layer and the bottom layer, and uses polyester high-elastic yarn as the middle layer, so that the fabric forms a raised structure 14 at the layered position, so that the fabric has a surface with a three-dimensional texture pattern. At the same time, the surface layer adopts an increased weft yarn thickness, so that the layered surface layer has sufficient tear resistance to avoid the occurrence of seams or tearing damage; the surface layer adopts an increased weft yarn thickness, and adopts a structure in which the warp yarns are merged into one strand at the boundary of the jacquard, so that the jacquard boundary strength is improved. At the same time, the raised area 14 on the surface of the fabric has a clear boundary, which increases the texture of the texture and makes the three-dimensional effect more prominent. In this way, a richer three-dimensional texture effect can be obtained, and by adding reinforcing yarns at the weft yarns of the surface layer, the fabric has a better tear resistance. In this way, at the raised area, the surface layer becomes the surface of the fabric as a single layer, and has sufficient tear resistance.

[0046] like Figure 1-2 As shown, the antibacterial layer 2 is made of antibacterial cotton, and the elastic thermal insulation layer 3 is made of wool. In this embodiment, the antibacterial layer 2 is made of antibacterial soft cotton, and antibacterial agents (such as silver ions, nano zinc oxide, etc.) are added to inhibit the growth of bacteria and mites. It is suitable for people with sensitive skin or allergies. The soft cotton material has a slight resilience, which can initially relieve body pressure and provide initial moisture absorption and buffering. Cotton fibers are naturally moisture-absorbent and breathable. Combined with antibacterial treatment, they reduce the reproduction of microorganisms in humid environments. The elastic thermal insulation layer 3 is made of wool, which uses the natural properties of wool to achieve elastic support and temperature and humidity regulation. The wool fiber has its own curling structure, providing "Q-elastic" resilience, supporting the body while maintaining flexibility. Natural wool has good thermal insulation properties. Wool is a natural fiber, and the active oxygen treatment has no chemical residue, which is in line with the concept of environmental protection.

[0047] like Figure 1-2 As shown, the flexible support layer 4 is made of latex sponge, and the dynamic support layer 5 is made of sponge. In this embodiment, the support feedback is improved by the high elasticity of latex, and the air permeability is enhanced at the same time. The honeycomb structure of natural latex provides uniform support and strong resilience, which is suitable for preventing spinal deformation. The sponge structure is light and thin, and can quickly conduct heat to avoid stuffiness near the spring layer. The natural antibacterial property of latex (oak protein) further strengthens the antibacterial ability of the mattress. The dynamic support layer 5 forms a three-dimensional mesh structure inside the sponge through a special weaving or molding process. This structure is similar to the frame structure in a building, with support units in all directions. When subjected to body pressure, the pressure will be dispersed and transmitted along the three-dimensional structure. It can be flexibly deformed with body movements to adapt to different sleeping positions such as turning over and lying on the side, reducing sleep interruptions. The material is light but the support force is concentrated, providing targeted support for easily suspended parts such as the waist and neck.

[0048] like Figure 1-2As shown, the reinforcement layer 6 is made of a multi-colored transitional fabric, and the cushioning layer 7 is made of sponge. In this embodiment, the multi-colored transitional fabric layer serves as a transition layer within the comfort layer, connecting materials of different densities to prevent slippage or collapse between layers. The sponge layer is a high-density sponge that absorbs pressure from various parts of the body, especially creating a wrapping effect on prominent areas such as the hips and shoulders. The sponge's porous structure absorbs friction noise when turning over.

[0049] like Figure 1-2 As shown, the filling layer 9 is made of fiber cotton, and the transition layer 10 is made of soft cotton. In this embodiment, the filling layer 9 is made of fiber cotton. The filling layer 9 is used to fill the gaps, cushion the touch of the springs, and enhance comfort. The fiber cotton is fluffy and soft, which can wrap around the edges of the springs to avoid a rough feeling. The air layer between the fibers improves the breathability of the mattress base and prevents the bottom from getting wet. Environmentally friendly fibers (such as recycled polyester fibers) can reduce costs and meet the environmental protection positioning of glue-free mattresses. The transition layer 10 is made of soft cotton and serves as a transition between the main support layer and the lower area, further softening the support hardness. The high-density material enhances the support strength of the mattress edge to prevent the edge from collapsing when sitting or lying down.

[0050] like Figure 1-2 As shown, the dustproof layer 11 is made of non-woven fabric, and the breathable layer 12 is made of mesh fabric. In this embodiment, the fine pores of the non-woven fabric can block tiny particles while allowing air to pass through, keeping the interior clean and protecting the spring layer from contamination. The mesh structure of the mesh fabric provides air circulation channels under the mattress, preventing long-term contact with the bed frame from causing dampness. The bottom mesh fabric has a slight anti-slip texture, which can fix the mattress to the bed frame and enhance the wear resistance of the bottom layer.
