[0003] However, in related art, the spring and support layer are typically secured together using plastic nails, with one end of the nail connected to the spring and the other end to the support layer. However, this method of securing the spring is less stable and can easily cause the spring to shift during use. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In this application, the terms "upper" and "lower" and other terms indicating positions or locations are based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0031] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to express a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "disposed" and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0033] Furthermore, the terms "first," "second," and the like are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0034] The structure of a mattress consists of four main parts: the fabric layer, the filling layer, the support layer, and the edge guard. The filling layer and the support layer are arranged sequentially along the thickness of the mattress, while the edge guard surrounds the outer perimeter of the filling layer and the support layer. The fabric layer covers the outer surfaces of the filling layer, the support layer, and the edge guard. The fabric layer determines the appearance and feel of the mattress, the filling layer determines the firmness and comfort of the mattress, the support layer determines the springiness of the mattress, and the edge guard provides support at the edges.

[0035] The support layer of a mattress is typically provided by springs, but in recent years, new materials have emerged, such as 3D cotton and 4D cotton. 3D cotton, also known as 3D upright cotton, features a sponge-like, three-dimensional structure of upright fibers or a honeycomb-like fiber mesh. 4D cotton is a material composed of densely intertwined synthetic fibers, forming a complex three-dimensional network structure. Both materials offer excellent elasticity and support, and are therefore used in mattress support layers. However, after prolonged use, they can cause sinkage, resulting in a decrease in support effectiveness.

[0036] To avoid the aforementioned issues, related technologies often incorporate springs into the support layer to create a modular mattress liner. Plastic nails are typically used to secure the springs to the support layer, with one end of the nail connected to the spring and the other to the support layer. However, this method of securing the springs is less stable, making it prone to spring displacement during use.

[0037] In view of this, embodiments of the present application disclose a mattress liner, a mattress having the same, and a bed. Multiple mounting holes are provided on the support layer of the mattress liner, and elastic members are disposed therein. The fiber filaments of the support layer located within the mounting holes are melted to form a connecting layer to connect the elastic members and the support layer. Compared to the method of separately providing fixing members, this arrangement helps to improve the stability of the connection between the elastic member and the support layer, thereby helping to improve the stability of the interior of the mattress and prevent the elastic member from shifting. Furthermore, by using the fiber filaments on the support layer to melt to form a connecting layer to secure the elastic member and the support layer, there is no need for additional fixing components, resulting in a simple structure and helping to simplify the assembly process of the mattress liner.

[0038] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0039] See also Figures 1 to 3 , Figure 1 is a schematic structural diagram of the support layer disclosed in the embodiment of this application, Figure 2 is a side view of the support layer disclosed in the embodiment of the present application, Figure 3 yes Figure 2 A partial enlarged view of point A in the middle. The mattress liner 100 disclosed in this application includes a support layer 1 and an elastic member 2. The support layer 1 is provided with a plurality of mounting holes 111, with fiber filaments 112 of the support layer 1 at least partially located within the mounting holes 111. The elastic member 2 is disposed within the mounting holes 111, and a connecting layer 3 is provided on the outer surface of the portion of the elastic member 2 located within the mounting holes 111. This connecting layer 3 is configured to secure the elastic member 2 to the inner wall of the mounting holes 111, thereby connecting the elastic member 2 and the support layer 1. The connecting layer 3 is formed by melting the fiber filaments 112 located within the mounting holes 111.

[0040] The mattress liner 100 disclosed in this application utilizes a connection layer 3 formed by melting fiber filaments 112 within mounting holes 111 of the support layer 1 to connect the elastic member 2 and the support layer 1. Compared to providing a separate connection member, such as a plastic nail, with one end connected to the elastic member 2 and the other end connected to the support layer 1, this method helps improve the connection stability between the elastic member 2 and the support layer 1, reduces or prevents displacement of the elastic member 2, and thus helps improve the stability of the mattress interior. Furthermore, the absence of additional fixing components helps simplify the structure of the mattress liner 100 and simplifies the assembly process of the mattress liner 100.

[0041] For example, the fiber filaments 112 may be melted by using a high-temperature flamethrower to quickly circle the mounting hole 111 , so that the fiber filaments 112 in the mounting hole 111 melt to form a connecting layer 3 to connect the elastic member 2 and the supporting layer 1 .

[0042] For some examples, see Figures 1 to 3 Considering that most mattress liners 100 are square, the support layer 1 is also square. Multiple mounting holes 111 are spaced apart along the length and width of the support layer 1. Each mounting hole 111 is provided with an elastic member 2. This arrangement of mounting holes 111 helps distribute pressure from various parts of the human body through the elastic members 2, thereby enhancing the support and service life of the support layer 1, and thus improving the support and service life of the mattress as a whole. Of course, as other examples, the mattress liner 100 can also be, for example, a circular mattress liner 100 or an oval mattress liner 100, in which case the support layer 1 is also circular or oval. Based on this, the mounting holes 111 can also be spaced apart along its diameter and in a direction parallel to its diameter.

[0043] In this embodiment, the mattress liner 100 is a square mattress liner 100 as a subsequent deployment method.

[0044] It is understood that the support layer 1 is composed of fiber filaments 112, and the fiber filaments 112 can be melted to form the connecting layer 3. Therefore, the material of the support layer 1 can be 3D cotton or 4D cotton. 3D cotton has good air permeability and uniform support, which helps to improve the air permeability of the support layer 1 and also helps to provide uniform support, improving the user's sleeping experience. 4D cotton has good elasticity and support, which helps to improve the support of the support layer 1 and effectively disperse pressure. This embodiment does not specifically limit this.

[0045] It can be understood that if the material of the support layer 1 is 3D cotton or 4D cotton, the material of the above-mentioned fiber filaments 112 can be polyester fiber, thermoplastic polyether / ester elastomer, thermoplastic silicone rubber, polyethylene or polyolefin elastomer, etc., and this embodiment does not make specific limitations on this.

[0046] It is understood that both 3D cotton and 4D cotton are materials composed of cross-arranged fiber filaments 112. The difference between the two is that 3D cotton is a three-dimensional mesh structure composed of two upper and lower surface layers and a middle portion of monofilaments. The two are woven into a mesh structure, and the middle layer is mainly composed of arc-shaped X-shaped cross-shaped monofilaments, which are arranged in parallel and cross-shaped. 4D cotton can be made of different types of synthetic fiber raw materials and has a multi-layer three-dimensional network structure formed by densely intertwined and interwoven fiber filaments 112. However, both materials are composed of arranged fiber filaments 112. The above-mentioned fiber filaments 112 in the mounting hole 111 are formed when the mounting hole 111 is provided on the support layer 1. Specifically, the mounting hole 111 can be formed by, for example, drilling a hole in the support layer 1. When the hole is opened in the support layer 1, some of the fiber filaments 112 of the support layer 1 will be located in the mounting hole 111. The fiber filaments 112 are trimmed so that they can adhere to the surface of the elastic member 2 in a molten state, thereby helping to fix the elastic member 2 and the support layer 1 through the molten fiber filaments 112.

[0047] It is understood that the above 3D cotton and 4D cotton materials are formed by filling with fiber filaments 112. The more the filling amount of fiber filaments 112 is, the stronger the support of the 3D cotton or 4D cotton is. For example, the thickness of 3D cotton is 2cm, and the filling amount of fiber filaments 112 can be 1250g / m 2 or 1600g / m 2 For example, the thickness of 4D cotton is 2cm, and the filling amount of the fiber 112 can be 1550g / m 2 or 2100g / m 2 This embodiment does not make any specific limitation on this.

[0048] Optionally, see Figures 1 to 3 The fiber filaments 112 are multiple in number, extending from the inner wall of the mounting hole 111 and arranged in a loop along the inner wall of the mounting hole 111. The arrangement of the fiber filaments 112 in a loop along the inner wall of the mounting hole 111 helps secure the fiber filaments 112 to the entire outer surface of the elastic member 2 after melting, thereby improving the connection stability between the elastic member 2 and the support layer 1, and thus improving the stability of the mattress liner 100. In addition, multiple fiber filaments 112 extend from the inner wall surface of the mounting hole 111, that is, one end of the fiber filament 112 is located in the supporting layer 1, and the other end is located in the mounting hole 111. The fiber filament 112 located in the mounting hole 111 is melted and fixed to the outer surface of the elastic member 2, and the other end of the fiber filament 112 is still located in the supporting layer 1, thereby realizing the connection between the elastic member 2 and the supporting layer 1. In this way, there is no need to set up additional fixing components, which helps to make the structure of the mattress liner 100 simpler and also helps to simplify the assembly process of the mattress liner 100.

[0049] For some examples, see Figures 1 to 3 The elastic member 2 is a spring, and the mounting hole 111 is a circular hole. The diameter of the mounting hole 111 is adapted to the outer diameter of the elastic member 2. The elastic member 2 is a spring. The spring has good support and can be adjusted in hardness and softness. This helps to improve the support of the support layer 1 by setting the spring in the mounting hole 111 on the support layer 1. It also helps to adjust the hardness of the elastic member 2 by setting springs of different models, thereby helping to adjust the hardness of the entire support layer 1 to meet the different usage requirements of users. In addition, the diameter of the mounting hole 111 is adapted to the outer diameter of the elastic member 2, which helps to make the connection between the mounting hole 111 and the elastic member 2 tighter, avoiding the elastic member 2 from shaking relative to the support layer 1 during the use of the mattress liner 100, helping to improve the stability of the mattress liner 100, and thus helping to improve the user experience.

[0050] It is understandable that the type of the above-mentioned spring can be an independent tube spring or an AGRO spring, etc., and this embodiment does not make any specific limitation on this.

[0051] It is understood that the material of the above-mentioned spring can be high-carbon steel, stainless steel, or titanium alloy. High-carbon steel has good hardness and wear resistance. Using high-carbon steel as the material of the spring helps to improve the hardness and wear resistance of the spring. Stainless steel has good corrosion resistance. Using stainless steel as the material of the spring helps to improve the corrosion resistance of the spring, thereby helping to increase the service life of the spring. Titanium alloy has high strength, good corrosion resistance, and is relatively light. Using titanium alloy as the material of the spring helps to improve the durability and lightness of the spring. This embodiment does not specifically limit this.

[0052] In some embodiments, the spring wire diameter includes at least one of 1.8 mm, 2.0 mm, and 2.2 mm. The spring wire diameter directly affects the spring's strength and load-bearing capacity. The larger the spring wire diameter, the higher the spring strength and the greater the load-bearing capacity. The strength relationship of the spring wire diameter is: 2.2 mm > 2.0 mm > 1.8 mm. The spring wire diameter can be selected based on the actual required support strength, and this embodiment does not impose any specific restrictions on this.

[0053] It is understandable that the support layer 1 is provided with a plurality of mounting holes 111, and springs are placed in the mounting holes 111. There are many different implementation methods for selecting the wire diameters of the plurality of springs. In one example, the wire diameters of the plurality of springs on the support layer 1 are the same. This arrangement helps to reduce the manufacturing cost and production complexity of the mattress liner 100. In another example, the wire diameters of the plurality of springs on the support layer 1 are different according to the region. For example, the spring with the largest wire diameter can be used for the position of the human buttocks, the spring with a smaller wire diameter can be used for the waist and legs, and the spring with the smallest wire diameter can be used for the position of the human head and feet. This method of using springs of different wire diameters in different regions helps to set springs of different elasticity according to different parts of the human body, so that each part of the body can be strongly supported, thereby helping to improve the user's sleeping comfort.

[0054] For some examples, see Figures 1 to 3 The height of the elastic member 2 is the same as the thickness of the support layer 1. This helps prevent the elastic member 2 from being higher than the thickness of the support layer 1, which could lead to direct contact between the body and the elastic member 2 and cause injury. It also helps prevent the elastic member 2 from being lower than the thickness of the support layer 1, which could result in insufficient support from the elastic member 2 to the support layer 1 and cause the support layer 1 to sag after a period of use.

[0055] It is understandable that the height of the spring may be greater than or equal to 10 cm, for example, 10 cm, 12 cm, 14 cm, 16 cm, or 18 cm, and the corresponding thickness of the support layer 1 may also be greater than or equal to 10 cm, for example, 10 cm, 12 cm, 14 cm, 16 cm, or 18 cm, etc. This embodiment does not specifically limit this.

[0056] For some examples, see Figures 1 to 3The support layer 1 includes multiple sublayers 11 along its thickness direction, and each sublayer 11 is provided with a mounting hole 111, and the mounting holes 111 on each sublayer 11 are all set through. Along the thickness direction of the support layer 1, the mounting holes 111 on each sublayer 11 are set in a one-to-one correspondence and are interconnected. Since the support layer 1 is composed of multiple sublayers 11 along its thickness direction, the overall thickness of the support layer 1 can be flexibly adjusted by increasing or decreasing the number of sublayers 11, which helps to flexibly adjust the support strength of the support layer 1. On the other hand, the number of sublayers 11 can also be adjusted to match the overall thickness of the support layer 1 with the height of the spring. For example, if the thickness of the sublayer 11 is 2 cm and the selected spring height is 10 cm, 5 layers of sublayers 11 can be set. If the spring height is increased to 12 cm, one layer of sublayer 11 can be added accordingly. In addition, the mounting holes 111 on each sublayer 11 are all set through, and the mounting holes 111 on each sublayer 11 are set one by one and connected to each other, which helps the spring to be set through the support layer 1 along the thickness direction of the support layer 1, and then helps the spring to better provide supporting force for the support layer 1, thereby helping to reduce or avoid the sinking of the support layer 1 after long-term use.

[0057] It is understandable that the material of each sub-layer 11 is the same, and can also be 3D cotton or 4D cotton, which will not be elaborated in this embodiment.

[0058] For some examples, see Figure 4 , Figure 4 Schematic diagram of the structure of the mattress liner disclosed in an embodiment of the present application. The mattress liner 100 further comprises a first layer 4 and a second layer 5, which are disposed at opposite ends of the support layer 1 along its thickness. The addition of the first layer 4 and the second layer 5 at opposite ends of the support layer 1 helps prevent dust and other debris from entering the mounting holes 111, thereby protecting the springs within the support layer 1 and improving the overall lifespan of the mattress liner 100. Furthermore, it helps prevent direct contact between the human body and the springs, which could cause injury.

[0059] In addition, the fabrics of the first layer 4 and the second layer 5 are the same as those of the support layer 1. That is, the fabrics of the first layer 4 and the second layer 5 can be 3D cotton or 4D cotton. This arrangement helps to avoid the situation where the fabrics of the additional first layer 4 and the second layer 5 are different from those of the support layer 1, thereby affecting the overall support of the mattress liner 100.

[0060] See also Figure 5 , Figure 5is a schematic diagram of the structure of a mattress disclosed in an embodiment of this application. Secondly, this application also discloses a mattress 200 comprising a fabric layer 201 and a mattress liner 100 as described in the first aspect above. The fabric layer 201 is disposed around the periphery of the mattress liner 100. The enveloping fabric layer 201 helps isolate dust from the air, protecting the mattress liner 100 within the mattress 200 and preventing wear and tear caused by direct contact between human skin and the mattress liner 100 structure.

[0061] It is understood that the fabric layer 201 can be one or more of knitted fabric, Tencel fabric, cotton and linen fabric, or bamboo fiber fabric. Knitted fabric has good air permeability and moisture absorption, is relatively affordable, and has good elasticity. Tencel fabric has good air permeability and moisture permeability, is more comfortable, and has good antibacterial properties. Cotton and linen fabric has an antistatic effect, is not easily deformed, absorbs sweat, and provides good comfort. Bamboo fiber fabric can effectively inhibit the growth of bacteria and mold, which helps maintain the hygiene of the mattress 200. It is also environmentally friendly and comfortable, and has good air permeability and moisture absorption. This embodiment does not specifically limit this.

[0063] In the third aspect, the present application also discloses a bed 300, the structure of which is as follows: Figure 6 As shown, Figure 6 3 is a structural diagram of a bed disclosed in an embodiment of the present application. The bed 300 comprises a bed body 301 and a mattress 200 as described in the second aspect above, the mattress being arranged on the bed body 301.
