Description

Technical Field

[0001] This utility model relates to the field of seat cushions, and in particular to a cooling seat cushion. Background Technology

[0002] When the weather temperature rises, sitting in a chair for a long time will cause heat to accumulate between the body and the chair surface. The temperature of the buttocks and back area will rise and produce sweat, thus creating a hot and humid environment for the skin of the buttocks and back. A hot and humid environment makes it difficult for people to concentrate at work, and may also cause some skin diseases such as prickly heat and eczema.

[0003] Currently, there are many chairs and cushions with fans on the market. Their working principle involves a fan generating airflow that is blown out through a perforated seat surface. This airflow is directed towards the buttocks and back to accelerate the evaporation of sweat from the skin, thus cooling it. However, this method of cooling the skin through airflow is not very effective when applied to chairs. The seat surface reduces the amount of air reaching the upper part of the seat. Due to structural limitations, the seat needs an air-guiding frame and must be made of a certain thickness of cotton, sponge, or foam to improve comfort. This reduces the amount of air reaching the upper part of the seat and coming into contact with the skin, thus affecting the cooling effect. Even if some chairs have additional ventilation holes to increase the airflow area, most of the area in contact with the body is still the seat surface. Furthermore, the poor breathability of this contact area can lead to heat buildup after prolonged sitting, resulting in poor cooling. Utility Model Content

[0031] like Figures 1 to 3As shown, an embodiment of the present invention provides a cooling seat cushion, comprising a seat cushion body 1, which includes a top layer 11 and an airflow channel. The top layer 11 is in direct contact with the human body and includes a heat-conducting component 3 for conducting body heat. A fan mounting part 2 is also provided on the seat cushion body for mounting a fan 21. The fan 21 provides active airflow into the airflow channel, which guides the active airflow across the surface of the heat-conducting component 3, thereby carrying away the heat emitted from the surface of the heat-conducting component 3 and accelerating heat dissipation. With this cooling seat cushion, when a user sits on the surface, the heat-conducting component 3 of the top layer 11 can quickly conduct heat from the user's buttocks, thus providing a cooling sensation. Furthermore, the active airflow continuously dissipates heat from the heat-conducting component 3, ensuring timely removal of the heat conducted by the component. This prevents heat accumulation between the seat cushion surface and the user's buttocks, reducing the temperature between the body and the seat cushion surface compared to ordinary seat cushions during prolonged sitting, and reducing sweating of the buttocks.

[0032] To enhance the cooling effect, it is preferable to have a height difference in the heat-conducting component 3, thereby directing heat away from the seat surface and the human body. Furthermore, active airflow is used to accelerate heat dissipation from the heat-conducting component 3, ensuring continuous and rapid heat removal from the seat surface. Specifically, such as... Figure 2 As shown, in one embodiment, the cushion body 1 includes a base 12 connected below the top layer 11, and an internal space 13 of the cushion body 1 is formed between the base 12 and the top layer 11. A fan mounting part 2 is disposed on the base 12 and is in fluid communication with the internal space 13, and the fan blows active airflow into the internal space 13. A support frame 14 supporting the top layer 11 is disposed in the internal space 13, and an air guiding structure (not shown in the figure) is disposed on the support frame 14 to guide the active airflow to flow more evenly in the internal space 13. The heat-conducting element 3 includes a support part 31 for supporting the human body and an extension part 32 connected to the support part 31 and extending toward the internal space 13 below the top layer 11. Since the temperature between the human body and the cushion surface is high, the support part 31 is used to conduct heat dissipated from the human buttock area, realize heat exchange between the heat-conducting element 3 and the human buttock, and transfer heat to the lower-temperature end of the extension part 32. By accelerating the airflow on the surface of the extension 32 through active airflow, the heat conducted by the extension 32 is dissipated into the internal space 13 and quickly dissipated with the active airflow.

[0033] Preferably, the upper surface of the support portion 31 extends substantially along a plane, which increases the heat conduction area between it and the human body, improving heat dissipation and cooling effect. In this embodiment, the heat-conducting element 3 can be made of a highly thermally conductive metal material, such as aluminum, copper, or aluminum alloy, or a highly thermally conductive composite material, such as thermally conductive plastic. To improve comfort, the top layer 11 also includes a soft pad 4, which is positioned above the support frame 14 and between the support frame 14 and the heat-conducting element 3. The soft pad 4 can be made of compressible sponge, foam, or soft rubber to improve the comfort of the user when sitting on the cushion surface. Furthermore, it is preferable that a plurality of support portions 31 are provided and spaced apart from each other on the plane of the top layer 11, and each support portion 31 is connected to its own extension portion 32. The support portions 31 are separated by the soft pad 4, which improves the softness of the top layer 11, facilitates the top layer 11 to conform to the human buttocks and deforms when changing sitting posture, thereby improving comfort.

[0034] In this embodiment, a groove is provided above the cushion 4, and the support part 31 can be fixed in the groove by adhesive. The air guiding structure on the support frame 14 is configured as several air guiding grooves, and a first airflow channel 8 for active airflow is formed in the air guiding grooves. The extension part 32 of the heat-conducting element 3 extends into the first airflow channel 8 and contacts the active airflow, thereby conducting and dissipating the heat between the cushion surface and the human body into the first airflow channel 8, so that the cushion surface can bring a continuous cooling sensation to the user. The cushion body 1 is also provided with an exhaust hole for the active airflow to be discharged, and the exhaust hole can be provided through the side of the cushion body 1.

[0035] like Figures 3-6 As shown, in another embodiment, the top layer 11 includes a base 5 placed on a support frame 14. A plurality of support blocks 51 extend from the base 5 toward the human body, spaced apart from each other. The upper surfaces of the support blocks 51 together form a first surface 16 on the top layer 11 for supporting the human body. In this embodiment, a heat-conducting element 3 covers the surfaces of the support blocks 51 and the upper surface of the base 5. The portion covering the first surface 16 constitutes the support portion 31 of the heat-conducting element 3, and the portion covering the sidewalls of the support blocks 51 and the base 5 constitutes the extension portion 32 of the heat-conducting element 3. Since the first surface 16 is located above the base 5, a height difference is formed between the support portion 31 and the extension portion 32 of the heat-conducting element 3. The support portion 31 can conduct heat between the human buttocks and the surface of the cushion to the extension portion 32 (see reference). Figure 6The dashed arrows indicate the direction of heat conduction, thus providing a cooling sensation to the seat surface. Furthermore, in this embodiment, the sidewalls of adjacent support blocks 51 and the base 5 located in the gap between the sidewalls together form a second airflow channel 7 for active airflow. The active airflow flowing in the second airflow channel 7 can carry away the heat conducted by the extension 32, thereby accelerating the heat conduction away from the support 31, improving the cooling effect of the seat surface and ensuring a continuous cooling sensation.

[0036] In use, the first surface 16 is the surface on which the seat cushion body 1 actually supports the human body. Preferably, the upper surface of the support block 51 extends substantially along the plane to increase the heat conduction area between it and the human body. Figure 5 and Figure 6 As shown, in this embodiment, the base 5 and the support block 51 are integrally formed and can be made of materials such as foam or rubber. The heat-conducting component 3 is a cooling fabric 6 made of a high thermal conductivity material and is covered on the surfaces of the base 5 and the support block 51 by adhesive. It should be noted that there are many types of cooling fabrics on the market. Classified by the principle of achieving cooling, some cooling fabrics reduce the contact area with the human body through ultra-fine fibers to produce an instantaneous cooling sensation, some cooling fabrics stimulate human skin receptors through a menthol coating to produce a pseudo-cooling sensation, some utilize fiber structure optimization to increase the fabric's moisture absorption and perspiration to accelerate sweat evaporation and produce a cooling sensation, and some use thermally conductive fibers to improve the thermal conductivity of the fabric to conduct heat from the body surface to the outside to produce a cooling sensation, such as adding thermally conductive fillers such as mineral powder and graphene to make thermally conductive fibers to improve the thermal conductivity of the fabric. In this embodiment, the heat-conducting component 3 specifically refers to a high thermal conductivity cooling fabric made of thermally conductive fibers. The cooling fabric 6 conducts heat away from the surface of the cushion, and combined with active airflow heat dissipation, the cushion produces a continuous cooling sensation.

[0037] In this embodiment, the cushion body 1 also includes a base 12 connected below the top layer 11, forming an internal space 13 between the base 12 and the top layer 11. A fan mounting part 2 is disposed on the base 12 and is in fluid communication with the internal space 13, blowing active airflow into the internal space 13. A connecting hole 9 is also provided through the base 5 located at the gap between the support blocks 51, connecting the second airflow channel 7 and the internal space 13. The active airflow can reach above the top layer 11 from the internal space 13 through the connecting hole 9 and flow in the gap between the side walls of the support blocks 51. In this embodiment, several connecting holes 9 are provided and evenly arranged on the cushion surface. When a person sits on the top layer 11, the active airflow flows in the second airflow channel 7 and also contacts the person. The active airflow laterally transmits the heat from the area 17 covered by the person's buttocks on the cushion surface to the area not covered by the person's buttocks along a direction generally parallel to the cushion plane, facilitating the dissipation of heat conducted by the heat-conducting component 3 and improving the cooling effect of the heat-conducting component 3. In addition, the heat-conducting component 3 can also consist of only the base 5 and the support block 51, which are integrally made of a thermally conductive material, such as thermally conductive gel. In this case, the upper surface of the support block 51 constitutes the support portion 31 of the heat-conducting component 3, and the sidewall of the support block 51 and the upper surface of the base 5 constitute the extension portion 32 of the heat-conducting component 3. Thermally conductive gel is a thermally conductive material made by adding fillers with high thermal conductivity, such as metal oxides, graphene, and ceramic particles, to ordinary gels such as silicone gel, epoxy resin, and polyurethane. Depending on the formulation and preparation process of the thermally conductive gel, the surface of the heat-conducting component 3, consisting of the base 5 and the support block 51 made of thermally conductive gel, may sometimes have natural adhesion. Therefore, a fabric layer 6, such as woven fabric, can be bonded to the surface of the base 5 and the support block 51 to encapsulate them. Alternatively, thermally conductive silicone can be used to integrally make the base 5 and the support block 51, and other thermally conductive materials can also be used.

[0038] The cooling seat cushion of this embodiment provides a method for reducing the temperature between the human buttocks and the support. By setting a heat-conducting element 3 on the top layer 11 of the support that is in contact with the human body, when the human body sits on the surface of the support, the support conducts heat away from the human skin surface; and by setting interconnected grooves 7 on the surface of the support, the heat-conducting element 3 extends into the grooves. The airflow provided by the fan conducts the human body heat conducted on the surface of the support through the grooves to the area of ​​the support surface not covered by the human buttocks, and finally dissipates into the air.

[0039] like Figure 8 As shown, you can also refer to Figure 4In addition to the above, this application also provides a simple cooling seat cushion, including a base 12 and a top layer 11 connected to the base 12, forming an internal space 13 between the base 12 and the top layer 11. A fan mounting package, fluidly communicating with the internal space 13, is connected to the bottom front end of the base 12. The fan mounting package has a first zipper opening 10, through which the fan can be inserted or removed. An air fiber pad 14 is disposed in the internal space 13 as a support frame; the porous air fiber pad also serves as an air guiding structure. A second zipper opening 15 is provided on the base 12, through which the air fiber pad can be inserted or removed from the internal space 13. The top layer 11 includes a base 5 and a plurality of support blocks 51 extending from the base 5 toward the human body, the support blocks 51 being spaced apart from each other. The base 5 and the support blocks 51 are integrally made of thermally conductive gel, and the top layer 11 also includes an encapsulating fabric layer 6 adhered to the surfaces of the base 5 and the support blocks 51. The upper surface of the support block 51 extends along the plane, and the edge of each support block 51 extends from its upper surface in a direction away from the human body. The edges of adjacent support blocks 51 are connected to form interconnected grooves 7 on the surface of the top layer 11. Several connecting holes 9 are provided through the grooves 7 to connect to the internal space 13. The active airflow generated by the fan passes through the air fiber pad and the connecting holes 9 and flows into the grooves. With this cooling cushion, the user can remove the fan and air fiber pad, and then fold the remaining cushion body 1 for easy carrying and transportation. Furthermore, the folded cushion body 1 can be refrigerated before inserting the fan and air fiber pad for even better cooling effect.
