[0034] The following will be combined with the drawings Figures 1-5 And the technical scheme of the utility model is further illustrated by the specific embodiment.

[0035] Please refer to Figure 1 The utility model embodiment provides a sofa, including sofa body 1. Among them, sofa body 1 mainly includes seat frame 11, backrest 12 and armrest 13 and the like components, backrest 12 and armrest 13 are fixedly set on seat frame 11, to constitute integral frame structure, here not to the specific setting mode of sofa body 1 make superfluous repetition.

[0036] Combined Figure 2 Sofa body 1 has soft pad 2. Optionally, soft pad 2 can be installed on the back cushion, seat frame 11 and armrest 13 respectively, and soft pad 2 has a flexible support layer 21 for providing flexible support to the human body; in the embodiment, the flexible support layer 21 adopts a sponge layer structure, the sponge layer has good support rebound function, and can well adapt to the actual use demand; in other embodiments, a layer structure with flexible support function such as silica gel, rubber, memory cotton can also be used, and this is not specifically limited, as long as a layer structure that can provide flexible support effect is used, it should be regarded as the equivalent replacement means of the present scheme.

[0037] On this basis, refer to Figure 3 And Figure 4In order to provide a suitable temperature for the sofa when in use, the constant temperature adjusting sofa further comprises a fiber layer 3 and a plurality of microcapsule pieces 4. Taking the soft cushion 2 arranged on the seat frame 11 as an example, the fiber layer 3 is embedded in the soft cushion 2 and connected with the flexible support layer 21. It needs to be explained that the connection here can be direct connection or indirect connection, and the specific connection mode of the flexible support layer 21 and the fiber layer 3 will not be described here. Exemplarily, when direct connection is adopted, only a mounting cavity needs to be arranged in the flexible support layer 21, and the fiber layer 3 is filled into the mounting cavity, and the flexible support layer 21 and the fiber layer 3 are directly attached together, so that the setting of the fiber layer 3 is completed.

[0038] At the same time, the microcapsule pieces 4 are implanted in the fiber layer 3. The microcapsule pieces 4 can be hollow spherical structures, and the microcapsule pieces 4 have a containing cavity filled with a thermally sensitive phase change medium 5. The thermally sensitive phase change medium 5 can absorb or release heat based on the ambient temperature. Specifically, the thermally sensitive phase change medium 5 (Thermally Sensitive Phase Change Materials, abbreviated as PCMs) is a kind of material that can undergo phase change (such as the transition between solid and liquid) within a specific temperature range. They store or release heat energy through physical state changes. The core characteristic is the heat absorption and release behavior near the phase change temperature. For example, when the material is heated to the phase change temperature, it will change from solid to liquid (or from liquid to gas), and during this process, a large amount of heat will be absorbed, which is called latent heat absorption. When the material cools down, the material will change from liquid to solid (or from gas to liquid), and release heat, which is called latent heat release.

[0039] In the above embodiment, by implanting the microcapsule pieces 4 in the fiber layer 3, the fiber has the function of absorbing, storing and releasing heat in the form of latent heat. At this time, by using the heat absorption and release function of the thermally sensitive phase change medium 5, the temperature of the soft cushion 2 can be adjusted when the indoor temperature changes. On the one hand, it does not need to be connected to electricity and other energy sources to achieve the purpose of constant temperature. On the other hand, the thermally sensitive phase change medium 5 can effectively maintain the stability of the surface temperature of the soft cushion 2, and the temperature adjusting effect has reliable persistence.

[0040] In the embodiments of the present application, with reference to Figure 4 and Figure 5 In order to realize the temperature control function of the fiber layer 3, the fiber layer 3 comprises a first sub-face layer 31 and a second sub-face layer 32, and the first sub-face layer 31 and the second sub-face layer 32 can be knitted by using knitting lines. At this time, the use of knitting forming can make the fiber layer 3 have soft properties, and the fiber layer 3 can be bent and deformed, and can adapt to more complex installation conditions.

[0041] The first sub-face layer 31 and the second sub-face layer 32 are connected by sewing the edges of the two layers to each other when they are arranged, at this time, the fiber layer 3 is formed, and at this time, the first sub-face layer 31 and the second sub-face layer 32 are parallel to each other, and the mounting gap is formed between the second sub-face layer 32 and the second sub-face layer 32, which provides a mounting space for the microcapsule 4.

[0042] Further, the microcapsule 4 is arranged in multiple, and the specific number of microcapsules can be arranged according to actual needs, and the specific number is not limited herein; the plurality of microcapsules 4 are arranged in the mounting gap, and the microcapsule 4 is embedded in the mounting gap, so as to realize the installation of the microcapsule 4.

[0043] It should be explained that the spacing space formed between the woven wires should be smaller than the size of the microcapsule 4, so as to avoid the microcapsule 4 from being loosened from the first sub-face layer 31 and the second sub-face layer 32, at this time, the microcapsule 4 in the displacement mounting gap is stably implanted, and the surrounding air is temperature-controlled and adjusted by the heat-sensitive phase change medium 5, so as to make the fiber layer 3 have the function of temperature control and adjustment to the outside.

In this embodiment, the heat conducting layer 6 adopts an aluminum foil layer as an example. Based on the use scenario of this embodiment, the aluminum foil layer has good bending flexibility and good plasticity, which well meets the actual application requirements.

[0046] Specifically, in order to realize the basic heat conduction effect, the opposite sides of the aluminum foil layer are closely attached to the surfaces of the flexible support layer 21 and the fiber layer 3 when the heat conducting layer 6 is arranged.
