Description

Technical Field

[0001] This utility model relates to the field of wind-controlled temperature mattress technology, and more specifically, to an energy-saving and environmentally friendly mattress with multi-dimensional cooling. Background Technology

[0002] A mattress is an item used to ensure that users get a healthy and comfortable sleep. There are many types of mattress materials, and mattresses made of different materials can provide different sleep effects. In the case of existing mattresses, in seasons with high temperature or humidity, especially in summer, mattresses are prone to feeling stuffy or sticky, which is not conducive to the user's sleep quality.

[0003] The most common type of mattress with a cooling effect is the water-filled mattress. It has a water-filled chamber inside the mattress. Before use, the water-filled mattress is placed in a low-temperature environment and used after it has cooled to a certain temperature. This cooling method is low in cost. However, because the heat capacity of the water-filled mattress is limited, after a period of use in a room temperature environment, the temperature of the mattress will be close to room temperature and it will not be able to continue to cool down. In addition, because it needs to be placed in a low-temperature environment before use, it is very inconvenient to move the water-filled mattress frequently. At the same time, the water-filled mattress has a high moisture content, which can easily breed bacteria and is not environmentally friendly. Long-term use may affect the user's health.

[0004] To address the aforementioned issues, existing patents disclose a mattress with a cooling device (Publication No.: CN206295163U, Publication Date: 20170704). This solution uses temperature and humidity sensors located on the mattress surface to obtain ambient temperature and humidity data. A controller drives an air conditioner and fan to regulate the ambient temperature, achieving a good cooling effect. However, this cooling technology has the following drawbacks: 1. It requires electricity and consumes energy; 2. The motor generates significant noise; 3. At higher temperatures, the airflow from the fan is too hot, resulting in poor cooling performance.

[0005] On the other hand, while air conditioning is effective in cooling the bedroom, it consumes a lot of energy due to the large cooling area it covers.

[0006] In summary, there is an urgent need for an environmentally friendly cooling pad that is energy-efficient and does not easily breed bacteria or other microorganisms.

[0007] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0056] Example 1

[0057] Figure 1 This is a structural schematic diagram of the energy-saving and environmentally friendly pad for multi-dimensional cooling provided in an embodiment of the present invention. Figure 2 for Figure 1 A perspective structural diagram of an energy-saving and environmentally friendly mat that provides multi-dimensional cooling. Figure 12 for Figure 1 A schematic diagram of the cooling pad body of an energy-saving and environmentally friendly pad that provides multi-dimensional cooling. Figure 17 for Figure 1 A schematic diagram showing the disassembled structure of the multi-dimensional cooling energy-saving and environmentally friendly pad. Please refer to the diagram. Figure 1 , Figure 2 , Figure 12 , Figure 17 The energy-saving and environmentally friendly multi-dimensional cooling pad provided in this embodiment includes an air supply unit 1 and a cooling pad body 2. The air supply unit 1 is installed at the corners of the cooling pad body 2. The cooling pad body 2 includes a bottom layer 21, a hollow structure airflow layer 22, a partitioned ventilation and heat dissipation layer 23, and a top layer 24. The bottom layer 21, the hollow structure airflow layer 22, the partitioned ventilation and heat dissipation layer 23, and the top layer 24 are sequentially stacked and sewn together with edging 25. The air supply unit 1 includes a fan 11, and the air outlet 111 of the fan 11 is connected to the hollow structure airflow layer 22. The partitioned ventilation and heat dissipation layer 23 has multiple ventilation areas 231, and the ventilation areas 231 have dense ventilation holes 232. The partitioned ventilation and heat dissipation layer 23 has multiple large ventilation holes 233 at both corners away from the air supply unit 1.

[0058] The surface layer 24 includes a cooling surface material 241 and a mesh fabric 242 sewn together at both ends of the cooling surface material 241 away from the air supply unit 1.

[0059] It should be noted that the surface layer 24 is spliced ​​at the two corners by the cooling surface material 241 and the mesh fabric 242, so that the air blown out from the ventilation holes 233 at the corners can be smoothly blown out from the mesh fabric 242 above the ventilation holes 233.

[0060] This utility model's multi-dimensional cooling energy-saving and environmentally friendly mat, when in use, blown by the fan 11 passes through the hollow structure airflow layer 22. A small portion of the airflow is dispersed to the surface layer 24 through the dense ventilation holes 232 on the ventilation area 231, giving the person lying on the surface layer 24 a slight cooling sensation. At the same time, most of the airflow passes through the hollow structure airflow layer 22 and is blown out through the large ventilation holes 233 at the corners of the ventilation area 231 via the mesh fabric 242. Some of the body heat of the person lying on the surface layer 24 enters the hollow structure airflow layer 22 through the surface layer 24. The air blown out through the large ventilation holes 233 of the hollow structure airflow layer 22 carries away the heat that has entered the hollow structure airflow layer 22. This multi-dimensional cooling effect is significant, and a satisfactory cooling effect can be achieved with a relatively low-power fan 11. Compared with existing technologies, it is significantly energy-saving. At the same time, the flowing airflow also has dehumidifying, sterilizing, and environmentally friendly functions.

[0061] Further reference Figure 1 The ventilation area 231 of this utility model is divided into a shoulder ventilation area, a back ventilation area, a buttock ventilation area and a leg ventilation area; the leg ventilation area is close to the air supply unit 1.

[0062] Furthermore, the hollow structure airflow layer 22 is a warp-knitted spacer fabric layer.

[0063] It should be noted that warp-knitted spacer fabrics are produced on double-needle-bed warp knitting machines, featuring a three-dimensional mesh structure with six-sided ventilation. The main advantages of warp-knitted spacer fabrics include excellent breathability and moisture permeability; the fabric's stiffness and elasticity can be adjusted by using different monofilaments; they offer good pressure dispersion, alleviating excessive localized pressure; and they are easy and convenient to recycle after disposal, causing no environmental pollution and contributing to energy conservation and environmental protection. Different raw materials and finishing processes can be used during production to achieve different hand feels and other functions, such as antibacterial and health-promoting properties.

[0064] Furthermore, the cooling material 241 is a nylon cooling fabric, or a polyethylene fiber blended cooling fabric, or a chemical fiber cooling fabric impregnated with a PCM phase material cooling finishing agent.

[0065] It should be noted that nylon fabric, also known as polyamide fiber, is a general term for thermoplastic resins containing repeating amide groups —[NHCO]— in their molecular backbone. Commonly used nylon / polyamide fibers can be divided into two main categories: one is obtained by direct condensation polymerization of diamine and diacid, such as nylon 66; the other is obtained by lactam condensation polymerization or ring-opening polymerization, such as nylon 6. These two types of fibers are mainly used for spinning synthetic fibers, and their most prominent advantages are that their abrasion resistance is higher than all other fibers and their thermal conductivity is also very high (the higher the thermal conductivity of the fabric material, the more obvious the cooling sensation). Polyethylene fiber blended fabrics utilize its fast heat conduction and smooth surface properties to bring a continuous cooling sensation; and the thermal conductivity of polyethylene fibers is the highest among common fibers.

[0066] It's worth noting that the moisture absorption of nylon fabric also affects the cooling sensation. For example, good moisture absorption utilizes water's high thermal conductivity to transfer heat away when the body sweats. Additionally, in nylon or polyethylene fiber blends, the irregular cross-sectional structure of some fibers can improve their heat transfer performance. These cross-sectional structures can enhance the fiber's sweat-wicking properties, thus increasing the cooling sensation.

[0067] In addition, the cooling sensation of synthetic fiber fabrics treated with PCM phase change material cooling finishing agent is affected by the finishing agent; specifically, the cooling finishing agent (LURCA-C99) is a textile temperature regulating agent developed by utilizing the theory of latent heat exchange, etc. PCM phase change material is a substance that changes phase with temperature (as the temperature rises, the substance changes from solid to liquid) and provides latent heat. During the phase change process, the phase change material can absorb or release a large amount of heat energy, while the temperature of the phase change material itself remains unchanged.

[0068] The xylitol and higher aliphatic hydrocarbon microcapsules it contains have a phase transition temperature slightly lower than body surface temperature (e.g., 28 degrees, 33 degrees, etc.), which can give people a cool and comfortable feeling.

[0069] It should be noted that the cooling-feeling processed fabrics are suitable for cooling-feeling home textiles, cooling-feeling masks, cooling-feeling non-woven fabrics, etc. After processing, the surface temperature of the textiles is suitable, making people feel cool and comfortable; they are non-toxic to the human body, non-irritating to the skin, meet environmental protection requirements, have no allergic reactions, and are easy to use.

[0070] Figure 18 for Figure 1 A schematic diagram of the planar structure of the energy-saving and environmentally friendly mat that provides multi-dimensional cooling. Please refer to... Figure 18 The cooling material 241 is a sandwich fabric 243 with a three-dimensional mesh structure, or it is made by splicing sandwich fabric 243 onto areas of the cooling fabric corresponding to the breathable area 231 (e.g., Figure 18 (As shown).

[0071] It should be noted that sandwich fabric 243 is a synthetic fabric woven by a warp knitting machine, consisting of three sides: top, middle, and bottom. Sandwich fabric 243 has the following main characteristics:

[0072] 1. Excellent breathability and moderate adjustment ability; its three-dimensional mesh structure earns it the reputation of a "breathable" fabric. Compared to other flat fabrics, Sandwich Fabric 243 offers superior breathability, maintaining a comfortable and dry surface through air circulation. 2. Unique elasticity; the mesh structure of Sandwich Fabric 243 undergoes high-temperature setting during production. When subjected to external force, it extends in the direction of the force, and when the tension decreases and is removed, the mesh returns to its original shape. The material maintains a certain elongation in both the horizontal and vertical directions without loosening or deforming. 3. Durable and wear-resistant, never pills; Sandwich Fabric 243 is made from tens of thousands of high-molecular synthetic fiber yarns refined from petroleum. It is warp-knitted using a knitting method, making it not only strong enough to withstand high-intensity tension and tearing but also smooth and comfortable. 4. Anti-mildew and antibacterial; the material undergoes anti-mildew and antibacterial treatment, inhibiting bacterial growth. 5. Easy to wash and dry; Sandwich fabric 243 is suitable for hand washing, machine washing, and dry cleaning, and is easy to clean; Three-layer breathable structure, ventilated and easy to dry.

[0073] This utility model's multi-dimensional cooling energy-saving and environmentally friendly mat uses a fan 11 and a cooling surface material 241 to cool down in multiple dimensions, resulting in a significant cooling effect. A relatively small fan 11 can achieve a satisfactory cooling effect, and compared with existing technologies, it is significantly more energy-efficient. At the same time, the flowing air also has dehumidifying, sterilizing and environmentally friendly functions.

[0075] It should be noted that by passing the stud 123 through the connecting hole, a stable connection is achieved between the soft material of the cooling pad body 2 and the hard material of the air supply unit 1; compared with traditional sewing and ultrasonic welding, the structure of this utility model by passing the stud through the connecting hole is simple and stable.

Figure 13 , Figure 14 , Figure 15 , Figure 16The hollow structure airflow layer 22 of this utility model includes an upper support plate 221, a lower support plate 222, a middle support pipe 223, and a surrounding edge 224; the upper support plate 221 and the lower support plate 222 are arranged in parallel and spaced apart, and the surrounding edge 224 is connected to the four sides of the upper support plate 221 and the lower support plate 222; a hollow cavity 225 is formed between the upper support plate 221, the lower support plate 222, and the surrounding edge 224. 25 is connected to the air outlet 111 of the fan 11; multiple rows of ventilation holes 226 are provided on the upper support plate 221, and corner air outlets 228 are provided at the two corners of the upper support plate 221 away from the ventilation holes 226; the ventilation holes 226 and the corner air outlets 228 are respectively aligned with the ventilation holes 232 and the ventilation holes 233; multiple middle support pipes 223 are connected between the upper support plate 221 and the lower support plate 222.

[0083] As can be seen from the above description, the advantages of this utility model are:

[0084] This utility model's multi-dimensional cooling energy-saving and environmentally friendly mat, when in use, blown by the fan 11 through the hollow structure airflow layer 22, a small portion of the air is dispersed to the surface layer 24 through the dense ventilation holes 232 on the ventilation area 231, giving the person lying on the surface layer 24 a slight cooling sensation; at the same time, most of the air is blown out through the large ventilation holes 233 at the corners of the ventilation area 231 through the hollow structure airflow layer 22; some of the body heat of the person lying on the surface layer 24 enters the hollow structure airflow layer 22 through the surface layer 24; the air blown out through the large ventilation holes 233 through the hollow structure airflow layer 22 carries away the heat that has entered the hollow structure airflow layer 22. This multi-dimensional cooling effect is significant, and a satisfactory cooling effect can be achieved with a relatively low-power fan 11, resulting in significant energy savings compared to existing technologies; simultaneously, the flowing air also has dehumidifying, sterilizing, and environmentally friendly functions.

[0085] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
