Description

Technical Field

[0001] This utility model relates to the field of soft pads, and more particularly to a self-breathing elastic soft pad. Background Technology

[0002] Soft cushions, including seat cushions, chair cushions, crawling mats, and yoga mats, are common household items that primarily serve to relieve pressure and provide comfort. Currently, these products are mainly made from soft materials, including sponge, polyurethane foam, EVA foam, silicone, gel, thermoplastic elastomers (TPE), linen, or 3D perforated fibers, all combined with different fabrics as an outer layer. Soft cushions primarily improve user comfort by increasing the contact area through the deformation of the filling material, thus providing cushioning. Soft cushions generally require softness, cushioning, breathability, and heating or cooling properties. For summer soft cushion products, consumers are particularly concerned about breathability and cooling effects.

[0003] Currently, most cushion fillings have poor thermal conductivity. With prolonged use, body heat is difficult to dissipate, increasing the seat surface temperature. Simultaneously, the moist heat from perspiration cannot escape promptly, leading to a damp and hot seat surface, resulting in decreased user comfort and even skin problems. Therefore, designing a cushion product with long-lasting cooling and a dry seat surface is crucial for improving user experience, especially for those who sit for long periods.

[0004] Recently, the market demand for summer cushion products has primarily focused on using honeycomb silicone materials, porous silicone, and cooling gel filling materials, combined with cooling fabrics to improve breathability and a cooling sensation. Currently, a utility model patent for a "Silicone Cooling Seat Cushion, Patent No.: CN212995675U" discloses a composite structure combining hexagonal porous honeycomb silicone material with cooling gel, which is considered to achieve both breathability and a cooling sensation, improving the comfort of the cushion.

[0005] The existing soft cushion products have the following design problems: (1) The hexagonal honeycomb holes are non-connected holes. After contact with the body, these non-connected holes will be blocked and become closed holes, resulting in poor air circulation; (2) The hexagonal holes have a mesh of hole walls. These hole walls will be severely deformed under the pressure of the body, increasing the hardness of the material. At the same time, the effective contact area between the hole walls and the body is small, resulting in increased local contact pressure on the body, which will cause indentations on the skin after the user sits for a long time; Secondly, the existing soft cushion products do not take into account the problem of sweat vapor generated by the body. The increased humidity of the seat surface caused by sweating will also affect the user's comfort. Utility Model Content

[0006] The purpose of this invention is to provide a self-breathing elastic rubber soft mat that is not only soft in texture and can distribute body weight when pressed on, but also has the functions of breathability, ventilation, cooling, and sweat absorption. It can be used as a seat cushion, crawling mat, sports mat, yoga mat and other soft mat products, significantly improving the user's comfort.

[0007] To achieve the above objectives, this utility model provides a self-breathing elastic rubber cushion, which utilizes material and structural characteristics to relieve pressure, reduce temperature, and decrease humidity. The cushion includes a cushion body, which includes a self-breathing elastic rubber layer with cooling and moisture self-balancing functions and a three-dimensional interconnected 3D knitted air layer. The 3D knitted air layer is disposed on at least one side of the self-breathing elastic rubber layer.

[0008] As a further improvement of this utility model, the self-breathing elastic adhesive layer is a resin-based composite material with thermal conductivity, water absorption, and softness. The resin-based composite material is a high thermal conductivity soft colloid material with a thermal conductivity greater than 0.5 W / m·K. The resin-based composite material contains hydrophilic structural units, which can reversibly physical adsorb water or water vapor. When the external humidity is greater than the physical equilibrium of the resin-based composite material, the resin-based composite material absorbs external moisture. When the external humidity is lower than the physical equilibrium of the resin-based composite material, the resin-based composite material releases the internally adsorbed water into the outside air.

[0009] As a further improvement of this utility model, the 3D knitted air layer consists of two layers, which are respectively disposed on both sides of the self-breathing elastic rubber layer. The 3D knitted air layer can maintain a three-dimensional interconnected structure under pressure, which can absorb external pressure impact and provide shock absorption function, and can also retain a continuous through-hole structure to maintain air circulation channels.

[0010] As a further improvement of this utility model, the main body of the cushion also includes a waterproof fabric and a bottom fabric, with the waterproof fabric, 3D knitted air layer, self-breathing elastic adhesive layer, 3D knitted air layer and bottom fabric arranged in sequence from top to bottom.

[0011] As a further improvement of this utility model, the bottom surface of the bottom material is provided with anti-slip particles.

[0012] As a further improvement of this utility model, the cushion also includes an annular edge seal, which covers the outer edge of the cushion body.

[0013] As a further improvement of this utility model, the thickness of the 3D knitted air layer is 0.5-10mm; the thickness of the self-breathing elastic adhesive layer is 0.5-10mm.

[0014] As a further improvement of this utility model, the breathable elastic adhesive layer is bonded to the 3D knitted air layer by the self-adhesive ability of the self-breathable elastic adhesive surface.

[0015] Beneficial effects

[0016] Compared with the prior art, the advantages of the self-breathing elastic rubber pad of this utility model are:

[0017] 1. Under external pressure, the 3D knitted air layer and self-breathing elastic gel of the cushion undergo elastic deformation to form a soft and shock-absorbing contact surface, reducing body pressure and improving comfort. In addition, due to the interconnected gap structure of the 3D knitted air layer, it can still maintain good connection under external pressure, thus forming an air passage between the body and the seat surface, improving the breathability of the seat surface.

[0018] 2. When a person is pressed on the self-breathing elastic cushion, some of the sweat vapor produced by their body is discharged from the seat surface through the air passage in the 3D knitted air layer. More importantly, most of the sweat vapor reaches the surface of the self-breathing elastic layer through the gaps in the 3D knitted air layer. The self-breathing elastic layer can quickly absorb the sweat vapor, thereby reducing the humidity of the seat surface and keeping the seat surface dry.

[0019] 3. Since the absorption of moisture by the self-breathing elastic layer is a physical process, when the human body leaves the cushion, there is no more sweat vapor produced by the human body on the seat surface, and the air humidity is low, the sweat vapor absorbed by the self-breathing elastic layer will be released back into the air, maintaining the stability of the self-breathing elastic pigment in the cushion and preventing it from being damaged due to continuous absorption of sweat vapor.

[0025] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] Example

[0027] The specific embodiments of this utility model are as follows: Figures 1 to 3 As shown, a self-breathing elastic rubber cushion utilizes material and structural characteristics to relieve pressure, reduce temperature, and decrease humidity. The cushion includes a main body, which comprises a self-breathing elastic rubber layer 3 with cooling and moisture self-balancing functions, and a three-dimensionally interconnected 3D knitted air layer 2. The 3D knitted air layer 2 is disposed on at least one side of the self-breathing elastic rubber layer 3. When the 3D knitted air layer is a single layer and the cushion is in contact with the human body, the 3D knitted air layer 2 is positioned on the side of the cushion closer to the human body. For example, when the cushion is used as a seat cushion, the 3D knitted air layer 2 is located above the self-breathing elastic rubber layer 3; when the cushion is used as a backrest cushion, the 3D knitted air layer 2 is located between the back of the human body and the self-breathing elastic rubber layer 3.

[0028] In this embodiment, the self-breathing elastic rubber cushion is a seat cushion, and the 3D knitted air layer 2 consists of two layers, which are respectively disposed on the upper and lower sides of the self-breathing elastic rubber layer 3.

[0029] The self-breathing elastic adhesive layer 3 is a resin-based composite material with thermal conductivity, water absorption, and flexibility. This resin-based composite material is a highly thermally conductive soft gel material with a thermal conductivity greater than 0.5 W / m·K. The resin-based composite material contains hydrophilic structural units, specifically hydrophilic functional groups. These hydrophilic structural units can reversibly adsorb water or water vapor. When the external humidity is higher than the physical equilibrium of the resin-based composite material, it absorbs external moisture; when the external humidity is lower than the physical equilibrium of the resin-based composite material, it releases the adsorbed water into the outside air.

[0030] The 3D knitted air layer 2 consists of two layers, which are respectively set on both sides of the self-breathing elastic rubber layer 3. The 3D knitted air layer 2 can maintain a three-dimensional interconnected structure under pressure, which can absorb external pressure impact and provide shock absorption function, and can also retain a continuous through-hole structure to maintain air circulation channels.

[0031] The main body of the cushion also includes a waterproof fabric 1 and a bottom fabric 5. The waterproof fabric 1, the 3D knitted air layer 2, the self-breathing elastic layer 3, the 3D knitted air layer 2 and the bottom fabric 5 are arranged in order from top to bottom.

[0032] The bottom surface of the bottom material 5 is evenly covered with multiple silicone anti-slip particles 6, which can increase the contact friction between the soft pad and the surface below (such as the top surface of the stool) and prevent the soft pad from slipping and affecting its use.

[0033] The cushion also includes an annular edge seal 4, which covers the outer edge of the cushion body, providing stability and aesthetic integrity to the entire multi-layer structure.

[0034] The self-breathing elastic layer 3 is a resin-based composite material, specifically using the gel damping shock-absorbing material described in document CN118725193A. This material has excellent thermal conductivity, allowing for rapid heat conduction and a noticeable cooling sensation upon contact with the body. Secondly, it effectively absorbs sweat vapor exhaled from the body, thereby controlling the humidity of the skin surface and maintaining a consistently dry feel, preventing stuffiness and dampness. Furthermore, the material possesses good flexibility, effectively resisting impact and absorbing energy. Therefore, as a filling material in cushioning systems, it can be used as a structural shock-absorbing material, effectively alleviating the pressure of body weight on the seat surface and improving the comfort of the cushion.

[0035] The 3D knitted air layer 2 is made of polyester fiber knitted fabric. The 3D knitted air layer 2 has a three-dimensional interconnected structure, including gaps that connect all outer surfaces (including sides, top, and bottom) and its internal space. It has high breathability, the fabric is soft and comfortable, and it maintains its three-dimensional interconnected structure even after compression, preserving breathability. The 3D knitted air layer 2 not only provides good support, preventing collapse under external pressure, but also has excellent breathability; even under pressure, the internal air layer remains interconnected, maintaining breathability. The 3D knitted air layer 2 can use air layer fabrics disclosed in documents such as CN216040071U and CN218857858U.

[0036] The thickness of the 3D knitted air layer 2 is 0.5-10mm. The thickness of the self-breathing elastic adhesive layer 3 is 0.5-10mm.

[0037] In this embodiment, the breathable elastic adhesive layer 3 is bonded to the 3D knitted air layer 2 by the self-adhesive ability of the breathable elastic adhesive surface.

[0038] Waterproof fabric 1 is a polyester fiber textile with a waterproof surface treatment, which provides waterproofing while retaining the ventilation and breathability of the fiber textile.

[0039] The bottom material 5 has excellent abrasion resistance and structural strength, which improves the structural stability of the cushion under lateral shear forces during use.

[0040] like Figure 3As shown, when a person sits on the cushion, the cushion is subjected to pressure, and the 3D knitted air layer 2 and the self-breathing elastic layer 3 of the cushion deform to form a soft and shock-absorbing contact surface, reducing the pressure on the body and improving comfort. In addition, due to the interconnected gap structure of the 3D knitted air layer 2, it can still maintain good connection under external pressure, thus forming an air passage between the body and the seat surface, improving the breathability of the seat surface.

[0041] Some of the sweat vapor produced by the user's body is expelled from the seat surface through air channels in the 3D knitted air layer 2, while most of the sweat vapor reaches the upper surface of the self-breathing elastic layer 3 through the gaps in the 3D knitted air layer 2. The self-breathing elastic layer can quickly absorb sweat vapor, thereby reducing the humidity of the seat surface and keeping it dry. The seat surface is the part of the cushion that comes into contact with the human body.

[0042] Since the absorption of moisture by the self-breathing elastic layer 3 is a physical process, when the human body leaves the cushion, there is no more sweat vapor generated by the human body on the seat surface, and the air humidity is low, the sweat vapor absorbed by the self-breathing elastic layer 3 will be released back into the air, maintaining the stability of the self-breathing elastic pigment in the cushion and preventing it from being damaged due to continuous absorption of sweat vapor.

[0043] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
