Description

Technical Field

[0001] This utility model relates to the field of sofa cushion technology, and in particular to a heat-dissipating sofa cushion. Background Technology

[0002] Most sofa cushions on the market currently employ a single-structure design, commonly including pure sponge cushions, pure cotton / linen fabric-covered cushions, or single-liquid cushions. While pure sponge cushions offer a degree of softness and support, the poor breathability of sponge means that heat generated in contact with the body during prolonged use is difficult to dissipate quickly, leading to localized overheating and sweating, especially in summer or warm environments, severely impacting user comfort. While pure cotton / linen fabric-covered cushions offer some breathability, their heat dissipation performance is limited if the internal filling remains traditional sponge, failing to meet users' needs for efficient heat dissipation. Furthermore, while single-layer liquid seat cushions offer some advantages in heat dissipation, the fluidity of the liquid results in insufficient support, leading to a less comfortable seating experience. Liquid seat cushions are also prone to leakage under pressure, resulting in a shorter lifespan. Additionally, most existing seat cushions do not employ a layered support plate structure, leading to poor overall structural stability. Over time, they are susceptible to deformation and collapse, affecting not only appearance but also further reducing comfort, making it difficult to achieve a balance between heat dissipation, support, and structural stability.

[0003] Therefore, it is necessary to provide a heat-dissipating sofa cushion to solve the above-mentioned technical problems. Utility Model Content

[0004] This invention provides a heat-dissipating sofa cushion, which solves the problem of poor heat dissipation in the prior art.

[0005] To address the aforementioned technical problems, this utility model provides a heat-dissipating sofa cushion. The core of the cushion consists of a first support plate and a second support plate, which are arranged parallel to each other vertically, serving as the basic support frame for the cushion. This arrangement provides a stable foundation for the subsequent installation of other components and ensures the overall structural balance of the cushion. A first cotton-linen woven sleeve is adhesively fixed to the upper surface of the first support plate. This adhesive connection ensures the stability between the first cotton-linen woven sleeve and the first support plate, preventing displacement during use. The first cotton-linen woven sleeve has a bag-like structure, with an internal cavity that precisely accommodates a sponge pad. The sponge pad is tightly fitted to the inner wall of the first cotton-linen woven sleeve and positioned above the first support plate. This tight fit allows the sponge pad to deform evenly under pressure. Simultaneously, the first cotton-linen woven sleeve prevents the sponge pad from directly contacting the human body, reducing wear and tear and improving tactile feedback. Correspondingly, on the upper surface of the second support plate, a second cotton and linen woven cover is also fixed by adhesive. The second cotton and linen woven cover is also bag-shaped, with a liquid seat cushion placed inside the cavity. The liquid seat cushion fills the internal space of the second cotton and linen woven cover and is positioned above the second support plate. The adhesive fixation ensures a stable connection between the second cotton and linen woven cover and the second support plate. The design of filling the cavity with liquid ensures the heat dissipation area of ​​the liquid seat cushion, thereby improving heat dissipation efficiency. In practical use, the first support plate provides a stable bottom support for the first cotton-linen woven cover and the sponge pad, preventing the sponge pad from shifting or collapsing excessively due to pressure. The sponge pad deforms when the user sits down due to its own elasticity, dispersing the pressure to the first support plate. The second support plate supports and positions the second cotton-linen woven cover and the liquid seat cushion. After absorbing body heat, the liquid seat cushion can dissipate heat through the breathable structure of the second cotton-linen woven cover. The second support plate can prevent the liquid seat cushion from deforming excessively due to gravity or external pressure, ensuring stable heat dissipation. At the same time, the first and second support plates work together to maintain the overall shape of the seat cushion. The combination of the two makes the support of the sponge pad and the heat dissipation of the liquid seat cushion complementary, greatly improving the overall performance of the seat cushion.

[0006] Preferably, Velcro fasteners are fixed to the upper surfaces of the first and second support plates, respectively. The Velcro fasteners are sheet-like and evenly distributed on the edges and center of the support plate surfaces. This edge and center distribution allows for more comprehensive subsequent connections and avoids unstable local connections. Correspondingly, Velcro fasteners are fixed to the lower surfaces of the first and second cotton-linen woven sleeves (the side in contact with the first support plate) and the second cotton-linen woven sleeves (the side in contact with the second support plate), respectively. The position and size of the Velcro fasteners are perfectly matched with the Velcro fasteners on the support plates. This compatibility is key to achieving a stable connection. Through the adhesive cooperation of the Velcro fasteners and the Velcro fasteners, the detachable connection between the first cotton-linen woven sleeve and the first support plate, and the second cotton-linen woven sleeve and the second support plate can be easily achieved. During use, the Velcro fasteners quickly and easily secure the cotton-linen woven cover to the support plate, ensuring that the cover will not detach from the support plate due to body movement, effectively guaranteeing the stability of the seat cushion structure. When cleaning or replacing the cover, simply pull the Velcro fasteners to separate them, and the cover can be easily removed, offering extremely convenient operation. Simultaneously, the Velcro connection ensures a tight fit between the cover and the support plate, preventing gaps that could cause displacement of the internal foam pad or liquid cushion, indirectly guaranteeing the support effect of the foam pad and the heat dissipation effect of the liquid cushion. Furthermore, the removable feature means that if the cover is damaged, the entire seat cushion does not need to be replaced, extending the lifespan of each component and significantly reducing maintenance costs.

[0007] Preferably, the first and second support plates are connected by a spring. One end of the spring is fixedly connected to the lower surface of the first support plate, and the other end is fixedly connected to the upper surface of the second support plate. The spring is perpendicular to the space between the two support plates. This perpendicular connection allows the spring to expand and contract evenly under force, avoiding uneven force distribution due to angular deviations. When a user sits down, body pressure is transmitted to the first support plate, which compresses the spring downwards. The spring generates an upward reaction force through its elasticity. This reaction force effectively buffers the pressure, reducing the impact of the body on the seat cushion and thus improving seating comfort. At the same time, the limited range of spring expansion and contraction restricts the distance between the first and second support plates, preventing the two support plates from getting too close and causing excessive compression of the internal sponge pad and liquid cushion. This ensures the elastic recovery ability of the sponge pad and the normal shape of the liquid cushion, maintaining the support and heat dissipation of the seat cushion. Furthermore, when the user stands up, the elasticity of the spring can also cause the first support plate to return to its original position, allowing the seat cushion to quickly return to its initial shape, preventing deformation from affecting subsequent use and extending the overall lifespan of the seat cushion.

[0008] Preferably, both the first and second cotton-linen woven covers have replacement openings on their sides. The length of the replacement opening is slightly less than half the circumference of the side of the woven cover. This length design meets the needs of removing and inserting the sponge pad and liquid seat cushion, while avoiding the overall structural stability of the woven cover due to an excessively large opening. A zipper is fitted at the edge of the replacement opening, and the zipper strap is sewn to the edge of the replacement opening. This sewing ensures the stability of the connection between the zipper and the woven cover. The zipper pull can slide along the zipper strap to open and close the replacement opening. When the zipper is closed, it seals the replacement opening, preventing the sponge pad inside the first cotton-linen woven cover and the liquid seat cushion inside the second cotton-linen woven cover from falling out of the replacement opening, ensuring the stability of the component position. When the sponge pad ages or the liquid seat cushion leaks and needs to be replaced, the zipper pull can be slid open to remove the old component and insert the new component through the replacement opening. The operation is convenient and requires no professional tools. At the same time, the zipper's sealing function reduces the amount of external dust and impurities entering the woven cover through the replacement opening, keeping the sponge pad and liquid seat clean and preventing dirt buildup from affecting performance and hygiene, thus indirectly ensuring the user experience of the seat.

[0009] Preferably, multiple springs are installed between the first and second support plates. All springs are of the same specification, ensuring uniform expansion and contraction under stress and preventing uneven support due to performance differences. The springs are distributed at equal intervals between the two support plates, forming a uniform support array. This uniform distribution ensures the support force covers the entire support plate area. Each spring is fixedly connected at both ends to the lower surface of the first support plate and the upper surface of the second support plate, respectively, preventing them from detaching under stress. During use, the multiple equally spaced springs evenly transmit the pressure on the first support plate to the second support plate, preventing deformation and damage due to excessive localized stress. This also ensures the first support plate remains horizontal under pressure, preventing tilting and providing a stable seating experience for the user, avoiding discomfort caused by tilting. The evenly distributed springs also form a stable elastic support system, improving the overall resistance to deformation of the cushion, preventing localized collapse after prolonged use, and extending the cushion's lifespan. Furthermore, in conjunction with the sponge pad, which provides soft support and the springs provide elastic cushioning, the overall support and comfort of the cushion are further enhanced.

[0010] Preferably, the liquid seat cushion consists of a PVC outer shell and an internal liquid. The PVC outer shell is a sealed, flexible, bag-like structure. The sealed design prevents internal liquid leakage, while its flexibility allows the liquid seat cushion to better conform to the contours of the human body. The internal cavity of the PVC outer shell is completely filled with liquid, and the liquid is in close contact with the inner wall of the PVC outer shell without any obvious gaps. This gap-free design allows the liquid to quickly transfer heat when absorbing it, avoiding any impact on heat conduction efficiency due to gaps. Furthermore, the PVC outer shell is entirely placed inside the second cotton-linen woven sleeve, fitting snugly against its inner wall. This snug fit allows for better heat transfer from the liquid seat cushion to the second cotton-linen woven sleeve. In practical use, the PVC outer shell seals the internal liquid, preventing leakage and ensuring the normal use of the liquid seat cushion. The internal liquid has excellent thermal conductivity; when the human body comes into contact with the PVC outer shell, the liquid quickly absorbs body heat and transfers it through the PVC outer shell to the external second cotton-linen woven sleeve. The breathable structure of the second cotton-linen woven sleeve then dissipates the heat into the air, achieving efficient heat dissipation. Meanwhile, the flexibility of the PVC cover allows the liquid cushion to adapt to the contours of the human body, improving its fit and enhancing seating comfort. The fluidity of the liquid further disperses the pressure exerted by the body. Combined with the support of the second support plate and the cushioning effect of the spring, this enhances the overall support of the cushion, providing both heat dissipation and support.

[0011] Compared with related technologies, the heat-dissipating sofa cushion provided by this utility model has the following beneficial effects: Compared to existing technologies, this heat-dissipating sofa cushion consists of a first support plate and a second support plate. A sponge pad is placed inside a first cotton-linen woven cover adhered to the surface of the first support plate, and a liquid cushion is placed inside a second cotton-linen woven cover adhered to the surface of the second support plate. This structural design effectively balances the cushion's heat dissipation, support, and structural stability, overcoming the shortcomings of existing single-structure cushions. On one hand, the sponge pad provides users with excellent softness and support, ensuring comfortable seating and avoiding poor seating comfort due to insufficient support. On the other hand, the liquid cushion has excellent heat dissipation performance, quickly absorbing and dissipating heat generated at the contact points between the body and the cushion, alleviating localized temperature increases and sweating, especially in summer or warm environments, significantly improving user comfort. Simultaneously, the first and second support plates enhance the overall structural stability of the cushion, effectively preventing deformation and collapse after long-term use, extending the cushion's lifespan, and breaking the dilemma of existing cushions struggling to balance heat dissipation, support, and structural stability.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0016] Please refer to the following: Figure 1-4A heat-dissipating sofa cushion is disclosed. The core of the cushion consists of a first support plate 2 and a second support plate 3, which are arranged parallel to each other vertically, serving as the basic support frame for the cushion. This arrangement provides a stable foundation for the installation of subsequent components and ensures the overall structural balance of the cushion. A first cotton-linen woven sleeve 4 is adhesively fixed to the upper surface of the first support plate 2. This adhesive connection ensures the stability between the first cotton-linen woven sleeve 4 and the first support plate 2, preventing displacement during use. The first cotton-linen woven sleeve 4 has a bag-like structure, with an internal cavity that precisely accommodates a sponge pad 7. The sponge pad 7 is tightly fitted to the inner wall of the first cotton-linen woven sleeve 4 and is positioned above the first support plate 2. This tight fit allows the sponge pad 7 to deform evenly under pressure. Simultaneously, the first cotton-linen woven sleeve 4 prevents the sponge pad 7 from directly contacting the human body, reducing wear and tear and improving the tactile feel. Correspondingly, on the upper surface of the second support plate 3, a second cotton and linen woven sleeve 5 is also fixed by adhesive. The second cotton and linen woven sleeve 5 is also bag-shaped, with a liquid seat cushion 9 placed in the internal cavity. The liquid seat cushion 9 fills the internal space of the second cotton and linen woven sleeve 5 and is positioned above the second support plate 3. The adhesive fixation ensures a stable connection between the second cotton and linen woven sleeve 5 and the second support plate 3. The design of filling the cavity with liquid ensures the heat dissipation area of ​​the liquid seat cushion 9, thereby improving the heat dissipation efficiency. In practical use, the first support plate 2 provides a stable bottom support for the first cotton and linen woven cover 4 and the sponge pad 7, preventing the sponge pad 7 from excessively shifting or collapsing due to pressure. The sponge pad 7 deforms when the user sits down due to its own elasticity, dispersing and transferring pressure to the first support plate 2. The second support plate 3 provides support and positioning for the second cotton and linen woven cover 5 and the liquid seat cushion 9. After absorbing body heat, the liquid seat cushion 9 can dissipate heat through the breathable structure of the second cotton and linen woven cover 5. The second support plate 3 can prevent the liquid seat cushion 9 from excessively deforming due to gravity or external pressure, ensuring stable heat dissipation. At the same time, the first support plate 2 and the second support plate 3 together maintain the overall shape of the seat cushion. The two work together to make the support of the sponge pad 7 and the heat dissipation of the liquid seat cushion 9 complementary, greatly improving the overall performance of the seat cushion. Example

[0017] Please refer to the following: Figure 1-4On the upper surfaces of the first support plate 2 and the second support plate 3, Velcro 10s are fixed respectively. The Velcro 10s are sheet-like and evenly distributed on the edges and center of the support plate surfaces. The distribution on the edges and center allows for more comprehensive subsequent connections and avoids unstable local connections. Correspondingly, on the lower surfaces of the first cotton-linen woven sleeve 4 (the side in contact with the first support plate 2) and the lower surfaces of the second cotton-linen woven sleeve 5 (the side in contact with the second support plate 3), Velcro males are fixed respectively. The position and size of the Velcro males are perfectly matched with the Velcro 10s on the support plates. This compatibility is the key to achieving a stable connection. Through the adhesive cooperation of the Velcro males and Velcro females 10s, the first cotton-linen woven sleeve 4 and the first support plate 2, and the second cotton-linen woven sleeve 5 and the second support plate 3 can be easily detachably connected. During use, the Velcro fasteners 10 and 10 quickly secure the cotton-linen woven cover to the support plate, ensuring that the cover will not detach from the support plate due to body movement, effectively guaranteeing the stability of the seat cushion structure. When cleaning or replacing the cover, simply pull the Velcro fasteners 10 to separate them, making the cover easy to remove – extremely convenient. Simultaneously, the Velcro connection ensures a tight fit between the cover and the support plate, preventing gaps that could cause displacement of the internal foam pad 7 or liquid seat cushion 9. This indirectly guarantees the support effect of the foam pad 7 and the heat dissipation effect of the liquid seat cushion 9. Furthermore, the removable feature means that the entire seat cushion does not need to be replaced when the cover is damaged, extending the lifespan of each component and significantly reducing maintenance costs. Example

[0018] Please refer to the following: Figure 1-4 The first support plate 2 and the second support plate 3 are connected by a spring 8. One end of the spring 8 is fixedly connected to the lower surface of the first support plate 2, and the other end is fixedly connected to the upper surface of the second support plate 3. The spring 8 is perpendicular to the space between the two support plates. This perpendicular connection allows the spring 8 to expand and contract evenly when under force, avoiding uneven force due to angular deviation. When the user sits down, the body pressure is transmitted to the first support plate 2, which compresses the spring 8 downward. The spring 8 generates an upward reaction force through its own elasticity. This reaction force can effectively buffer the pressure, reduce the impact of the human body on the seat cushion, and thus improve the comfort of sitting. At the same time, the limited range of expansion and contraction of the spring 8 can limit the change in distance between the first support plate 2 and the second support plate 3, preventing the two support plates from getting too close and causing excessive compression of the internal sponge pad 7 and liquid seat cushion 9. This ensures the elastic recovery ability of the sponge pad 7 and the normal shape of the liquid seat cushion 9, maintaining the support and heat dissipation of the seat cushion. In addition, when the user gets up, the elasticity of the spring 8 can also drive the first support plate 2 to reset, so that the seat cushion can quickly return to its initial shape, avoid the inability to recover due to deformation and affect subsequent use, and extend the overall service life of the seat cushion. Example

[0019] Please refer to the following: Figure 1-4 Both the first cotton-linen woven cover 4 and the second cotton-linen woven cover 5 have replacement openings on their sides. The length of the replacement opening is slightly less than half the circumference of the side of the woven cover. This length design meets the needs of removing and inserting the sponge pad 7 and the liquid seat cushion 9, while avoiding the overall structural stability of the woven cover due to an excessively large opening. A zipper 6 is fitted at the edge of the replacement opening. The zipper 6 is sewn and fixed to the edge of the replacement opening, ensuring the stability of the connection between the zipper 6 and the woven cover. The zipper pull can slide along the zipper pull to open and close the replacement opening. When the zipper 6 is closed, it seals the replacement opening, preventing the sponge pad 7 inside the first cotton-linen woven cover 4 and the liquid seat cushion 9 inside the second cotton-linen woven cover 5 from falling out of the replacement opening, ensuring the stability of the component positions. When the sponge pad 7 ages or the liquid seat cushion 9 leaks and needs to be replaced, the zipper 6 can be opened by sliding the zipper pull, allowing the old component to be removed and the new component to be inserted through the replacement opening. The operation is convenient and requires no professional tools. Meanwhile, the sealing effect of zipper 6 can reduce the entry of external dust and impurities into the woven cover through the replacement port, keeping the sponge pad 7 and liquid seat cushion 9 clean, avoiding the impact of dirt accumulation on performance and hygiene, and indirectly ensuring the user experience of the seat cushion. Example

[0020] Please refer to the following: Figure 1-4 Multiple springs 8 are installed between the first support plate 2 and the second support plate 3. All springs 8 are of the same specification. The uniform specification ensures that the expansion and contraction performance of each spring 8 is the same when subjected to force, avoiding uneven support due to performance differences. The multiple springs 8 are distributed between the two support plates at equal distances, with the spacing between adjacent springs 8 being the same, forming a uniform support array. The uniform distribution allows the support force to cover the entire support plate area. The two ends of each spring 8 are fixedly connected to the lower surface of the first support plate 2 and the upper surface of the second support plate 3, respectively. The fixed connection ensures that the spring 8 will not fall off when subjected to force. During use, multiple equidistantly distributed springs 8 can evenly transmit the pressure on the first support plate 2 to the second support plate 3, preventing deformation and damage caused by excessive force on some springs 8. At the same time, it ensures that the first support plate 2 remains horizontal when under pressure, preventing tilting and ensuring a stable seating experience for the user, avoiding physical discomfort caused by tilting. The evenly distributed springs 8 can also form a stable elastic support system, improving the overall anti-deformation ability of the seat cushion, preventing local collapse after long-term use, and extending the service life of the seat cushion. At the same time, in conjunction with the sponge pad 7, the sponge pad 7 provides soft support and the springs 8 provide elastic cushioning, further enhancing the support and comfort of the seat cushion. Example

[0021] Please refer to the following: Figure 1-4The liquid cushion 9 consists of a PVC outer shell and an internal liquid. The PVC outer shell is a sealed, flexible, bag-like structure. The sealed design prevents internal liquid leakage, while its flexibility allows the liquid cushion 9 to better conform to the contours of the human body. The internal cavity of the PVC outer shell is completely filled with liquid, ensuring close contact between the liquid and the inner wall of the PVC outer shell without any noticeable gaps. This gap-free design allows for rapid heat transfer when the liquid absorbs heat, avoiding any impact on heat conduction efficiency due to gaps. Furthermore, the PVC outer shell is entirely placed inside the second cotton-linen woven sleeve 5, fitting snugly against its inner wall. This close fit allows for better heat transfer from the liquid cushion 9 to the second cotton-linen woven sleeve 5. In actual use, the PVC outer shell seals the internal liquid, preventing leakage and ensuring the normal operation of the liquid cushion 9. The internal liquid has excellent thermal conductivity; when the human body comes into contact with the PVC outer shell, the liquid quickly absorbs body heat and transfers it through the PVC outer shell to the external second cotton-linen woven sleeve 5. The breathable structure of the second cotton-linen woven sleeve 5 then dissipates the heat into the air, achieving efficient heat dissipation. Meanwhile, the flexibility of the PVC cover allows the liquid cushion 9 to adapt to the contours of the human body, improving its fit and enhancing seating comfort. The fluidity of the liquid further disperses the pressure applied by the human body. Combined with the support of the second support plate 3 and the cushioning effect of the spring 8, the overall support effect of the cushion is improved, achieving dual protection of heat dissipation and support.

[0022] The working principle of the heat-dissipating sofa cushion provided by this utility model is as follows: When a user sits on the cushion, their body weight is first transferred to the first cotton-linen woven sleeve 4 on the surface of the first support plate 2, and then to the internal sponge pad 7. The sponge pad 7, with its good elasticity and support, adapts to the user's body contours, closely conforming to the body curves and distributing pressure, providing a soft and stable seating experience. Simultaneously, the first and second support plates 2 and 3, acting as a skeletal structure, bear and transmit pressure, preventing excessive compression and deformation of the sponge pad 7 and the liquid cushion 9, maintaining the overall structural shape and stability of the cushion. During use, the heat generated at the contact points between the user's body and the cushion is quickly absorbed by the liquid cushion 9 inside the second cotton-linen woven sleeve 5 on the surface of the second support plate 3. The liquid, with its good thermal conductivity and fluidity, evenly distributes the heat to all areas of the liquid cushion 9, increasing contact with the outside environment. The second cotton-linen woven cover 5 has a large contact area, and its breathable cotton-linen material accelerates the dissipation of heat from the surface of the liquid seat cushion 9, allowing heat to quickly escape from the outside of the cushion, preventing heat accumulation, effectively reducing local temperature and sweating, and maintaining a comfortable usage temperature environment. In addition, the Velcro 10 on the surface of the first support plate 2 and the second support plate 3 are tightly attached to the Velcro male on the surface of the first and second cotton-linen woven covers 5, ensuring that the cotton-linen woven covers are firmly connected to the support plates and preventing the woven covers from shifting or falling off during use. When it is necessary to clean or replace the woven covers, the user only needs to gently tear to separate the Velcro male and Velcro female 10 to remove the woven covers. After cleaning or replacing with a new woven cover, align and press to complete the installation. The operation is convenient and efficient, providing convenience for daily maintenance while ensuring the cleanliness and integrity of the seat cushion for long-term use.
