[0002] In the use and design of seat cushions, a soft filling layer is usually provided on the seat cushion to provide better support and comfort, such as a sponge pad or a gel pad. The filling layer is generally laid over a large area on the backrest and seat cushion of the seat cushion. Although the above filling layer itself has certain heat absorption properties, it is composed of numerous tiny holes inside, and these holes are difficult to form a continuous heat transfer channel, causing the heat to stay in the filling layer for too long and not easy to dissipate. In addition, there is a large contact area between the seat cushion and the human body. The longer the sitting time, the more difficult it is for the heat to dissipate, which will cause the temperature of the seat cushion surface to become higher and higher, causing a feeling of stuffiness and discomfort to the user.

[0003] Therefore, a seat cushion with a heat dissipation channel is designed to keep the seat cool, clean and hygienic for a long time. Utility Model Content

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] As Figures 1 to 6 shown, a seat cushion with a heat dissipation function includes a seat cushion body 1. The seat cushion body 1 is divided into a backrest part 2, a lumbar support part 3, and a seat cushion part 4. A first filling layer 201 is laid on the backrest part 2. A plurality of first heat dissipation channels 202 are provided on the top surface of the first filling layer 201. Both ends of the first heat dissipation channels 202 communicate with the peripheral wall of the first filling layer 201. A second filling layer 401 is laid on the seat cushion part 4. A plurality of second heat dissipation channels 402 are provided on the top surface of the second filling layer 401. Both ends of the second heat dissipation channels 402 communicate with the peripheral wall of the second filling layer 401. Both the first filling layer 201 and the second filling layer 401 are composed of a gel pad 5 and a plurality of air holes 6; the air holes 6 are arranged in a honeycomb shape; both the first heat dissipation channels 202 and the second heat dissipation channels 402 are symmetrically arranged and are arc-shaped and extendedly provided on the gel pad 5; the first heat dissipation channels 202 extend upward to the upper edge of the seat cushion body 1 and downward to the lumbar support part 3; the second heat dissipation channels 402 extend backward to the lumbar support part 3 and forward to the front edge of the seat cushion body 1; heat dissipation holes 7 are symmetrically opened on the lumbar support part; a raised part 8 is formed by the upward bulge in the middle of the front edge of the seat cushion part 4, and both sides of the raised part 8 extend outward in an arc shape to form a recessed part 9; the upper edge of the backrest part extends backward in an arc shape to form a stretching part 10, and both sides of the stretching part 10 extend forward in an arc shape to form a wrapping part 11.

[0024] The present utility model sets the first filling layer 201 and the second filling layer 401 as gel materials, and arranges the gel pads 5 in a honeycomb pattern to form a plurality of honeycomb-shaped air holes 6. While the gel itself has heat absorption performance, the setting of the plurality of air holes 6 helps air circulation, reduces the stuffy feeling during long sitting, and also reduces sweat accumulation, and can still keep cool after long-term use; a plurality of first heat dissipation channels 202 and second heat dissipation channels 402 are respectively formed on the first filling layer 201 and the second filling layer 401. Then, the heat of the two parts can be preliminarily dissipated through the air holes 6 on the gel pad 5, and the heat accumulated after long sitting will flow outwards sequentially along the first heat dissipation channel 202 and the second heat dissipation channel 402, thereby taking away the heat, reducing the temperature of the surface of the seat cushion body 1, keeping the seat cushion body 1 dry after long sitting, and achieving effective heat dissipation; and heat dissipation holes 7 are symmetrically formed on the lumbar support part, and the heat dissipation holes 7 can enable the air inside the seat cushion to communicate with the outside, including the heat flowing downward through the heat dissipation channel from the backrest 2 and the heat flowing backward from the seat cushion part 4, effectively reducing the stuffy feeling of the waist and back, keeping the surface of the backrest cool, and improving the comfort of use.

[0025] Embodiment 2

[0026] As Figures 1 to 6 shown, a seat cushion with a heat dissipation function includes a seat cushion body 1. The side of the seat cushion body 1 forms an "L" shape to conform to the sitting posture of the human body. At the same time, the seat cushion body 1 is divided into three parts, namely, a backrest 2 for supporting and contacting the back, a lumbar support part 3 for supporting and contacting the waist, and a seat cushion part 4 for supporting and contacting the buttocks, and the heat dissipation of the three parts is processed separately. Since the buttocks and the waist are the main parts of the human body that bear pressure in the sitting posture, a first filling layer 201 and a second filling layer 401 are respectively laid on the positions of the backrest 2 and the seat cushion part 4 close to the human contact surface for processing the comfort of the positions with a large contact area, and relieve the pain and discomfort caused by excessive local pressure by dispersing the pressure; a good filling layer can support the waist, reduce the force exerted by the waist, relieve the pressure on the sciatic nerve, reduce the force on the sciatic nerve, and reduce the negative impact of long-term sitting on the body, such as lumbar pain and sciatic nerve pain; it can also improve the comfort of the sitting posture, reduce the fatigue of the buttocks and thighs, improve blood circulation, and prevent the occurrence of diseases such as varicose veins and hemorrhoids.

[0027] The first filling layer 201 and the second filling layer 401 are made of a variety of materials, such as common sponges, gels, etc. When the material for preparing the filling layer is a sponge, due to its good elasticity and softness, it can closely fit the human body curve, providing comfortable support for the buttocks and waist; a suitable sponge can also provide good support for the waist, maintaining the normal physiological curvature of the waist, reducing the stress on the waist, reducing fatigue, and improving the comfort of sitting posture. However, considering that sponges are prone to heat absorption, which causes the temperature of the surface of the seat cushion body 1 to rise and is inconvenient for heat dissipation. Furthermore, when the user sits for a long time, the sponge is difficult to ventilate through breathable materials because it is always wrapped in the outer fabric, extremely prone to bacteria and odors, unable to keep the seat cushion fresh, clean, and hygienic, and is likely to cause discomfort and harm to the body over time. In addition, the sponge will collapse after sitting for a long time, making it inconvenient for long-term use. Therefore, in this embodiment, gel is specifically selected as the material for preparing the filling layer. It is understandable that the preparer can also make a choice according to requirements.

[0028] When the filling layer uses gel as the preparation material, it can relieve the stuffy feeling generated by the human body after sitting for a long time through its inherent cool touch. At the same time, its excellent support and resilience enable the seat cushion body 1 to quickly return to its original state even after long-term use, maintaining the durability and comfort of the seat cushion body 1; moreover, due to the hydrophobicity of the gel, it only needs to be wiped with a wet cloth during cleaning, and the two cooperate to keep the seat cushion body 1 clean and fresh, reducing bacteria growth and odor generation.

[0029] Embodiment 3

[0030] In Embodiment 2, it is mentioned that "the filling layer uses gel as the preparation material", which can keep the seat cushion body 1 clean and fresh and bring comfort to the human body. However, the filling layers provided on the backrest 2 and the seat part 4 are all laid in a large, integral piece. When the entire weight of the human body presses on the gel pad 5, even though it has good heat absorption performance itself, after sitting for a long time, the generated heat will stay on the surface of the gel and still cannot be quickly dissipated into the external air, which will cause the temperature of the seat cushion surface to rise, bringing a stuffy and uncomfortable feeling to the user. Therefore, the gel pad 5 is also arranged in a honeycomb pattern, forming multiple honeycomb-shaped pores 6, which helps air circulation and reduces sweat accumulation.

[0031] Moreover, the honeycomb arrangement design enables the gel pad 5 to have a large number of air holes 6, which helps air circulation, reduces the stuffy feeling during long periods of sitting, and also reduces sweat accumulation. It can remain cool after long-term use, reduce bacterial growth and odor generation, and the occurrence of hemorrhoids after prolonged sitting. On this basis, a plurality of first heat dissipation channels 202 and second heat dissipation channels 402 are respectively provided on the top surfaces of the first filling layer 201 and the second filling layer 401 (i.e., the gel pad 5). Furthermore, both ends of the first heat dissipation channel 202 communicate with the peripheral wall of the first filling layer 201, and both ends of the second heat dissipation channel 402 communicate with the peripheral wall of the second filling layer 401. When a person sits upright on the seat cushion body 1 normally, the back contacts the first filling layer 201 on the backrest 2, and the buttocks contact the second filling layer 401 on the seat cushion part 4. After prolonged sitting, the heat accumulated in the two parts can flow out through the first heat dissipation channel 202 and the second heat dissipation channel 402. Among them, the first heat dissipation channel 202 and the second heat dissipation channel 402 are both symmetrically arranged left and right, and are successively arranged as channels a, b, c, d. Channel a is symmetrically arranged on the outermost side, channel d is symmetrically arranged on the innermost side, and channels a, b, c, d are all arc-shaped extensions along the direction of the gel pad 5; channels a, b, c, d located on the first filling layer 201 all extend upward to the upper edge of the seat cushion body 1 and downward to the lumbar support part 3, while channels a, b, c, d located on the second filling layer 401 all extend backward to the lumbar support part 3 and forward to the front edge of the seat cushion body 1. That is, when a person sits upright on the seat cushion body 1 normally, the back contacts the backrest 2, and the buttocks contact the seat cushion part 4. The heat of the two parts can be initially dissipated through the air holes 6 on the gel pad 5. After prolonged sitting, the accumulated heat will flow out successively along the heat dissipation channels (i.e., channels a, b, c, d), thereby taking away the heat, reducing the temperature on the surface of the seat cushion body 1, keeping the seat cushion body 1 dry after prolonged sitting, and reducing bacterial growth.

[0032] Furthermore, heat dissipation holes 7 are symmetrically provided on the support part. The heat dissipation holes 7 can enable the air inside the seat cushion to communicate with the outside, including the heat flowing downward through the heat dissipation channels from the backrest 2 and the heat flowing backward from the seat cushion part 4, effectively reducing the stuffy feeling in the waist and back, keeping the surface of the backrest cool, and improving the comfort of use.

[0033] It can be understood that the number of heat dissipation channels can determine the heat dissipation effect. The more heat dissipation channels, the better the heat dissipation effect; but correspondingly, the more heat dissipation channels are provided, the fewer support points there are, and it cannot provide a good and comfortable support feeling for the human body and cannot meet the basic needs of users. Therefore, neither the number nor the position of the heat dissipation channels is limited, and it can be designed according to the actual needs of the seat cushion body 1.

[0034] Embodiment 4

[0035] While the seat cushion body 1 satisfies effective heat dissipation, the seat cushion body 1 can also be modified to conform to the ergonomic principle, and to a certain extent, it can play a role in correcting the sitting posture of the human body.

[0036] Among them, the front edge of the seat cushion part 4 is set in a "ω shape", that is, both left and right ends extend upward while showing a tendency to curl inward. At the same time, the middle part of the front edge of the seat cushion part 4 bulges upward to form a raised part 8. Both sides of the raised part 8 cooperate with the outer edge of the seat cushion part 4 to form 2 recesses 9 for supporting the thigh parts of the human body. When the human body is sitting on the seat cushion, the thighs will be respectively located in the recesses 9, and the middle raised part 8 can form a certain distance between the thighs, effectively preventing the human body from having improper sitting postures such as crossing legs or sitting cross-legged. The left and right sides of the backrest part 2 extend forward in an arc, and together with the lumbar support part 3, they present a wrapped design to form a wrapped part 11; at the same time, the upper edge of the backrest part forms an arc-shaped extension backward to form a stretching part 10. Then, when the human body sits on the seat cushion and leans the back on the backrest part, the support part can support the waist of the human body, and at the same time, the entire back relies on the backrest part for support. According to the spinal alignment of the human body, the higher the stretching part 10, the more backward the back will be stretched, and the upper edge of the stretching part 10 can perfectly fit the alignment of the human back, providing correct and comfortable sitting posture support.
