Description

Technical Field

[0001] This utility model relates to the field of memory foam technology, and more specifically to a high-elasticity gradient composite memory foam. Background Technology

[0002] Current memory foam typically uses multiple layers of memory foam with gradually decreasing softness from top to bottom, bonded together in a gradient composite (fixed using spray adhesive or liquid adhesive). The softer memory foam at the top provides a good feel and comfort, while the firmer memory foam at the bottom provides sufficient support to better adapt to the curves of the human body, reduce pressure, and improve comfort; and the bottom layer uses a firmer memory foam material to provide strong support for the body. Although the existing "as described in application number: CN201921475317.5, a spring cushion wrapped with memory foam" states that "two pieces of memory foam are connected to each other by springs to increase their elasticity. When the surface is compressed, the springs provide support and can quickly rebound, promote blood circulation, reduce pressure on the lumbar spine, and relieve fatigue," the overall rebound position is relatively limited and the effect is not good. Utility Model Content

[0003] The purpose of this utility model is to provide a highly elastic gradient composite memory foam in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a high-elasticity gradient composite memory foam, which includes a cotton body, and the cotton body includes a first cotton layer, a second cotton layer and a third cotton layer that are sequentially bonded and fixed from bottom to top. The softness of the first cotton layer, the second cotton layer, and the third cotton layer increases sequentially. It also includes a projectile-assisting assembly, which includes a first spring, a second spring, and a third spring fixed from bottom to top, as well as a lower cavity, a through cavity, and an upper cavity that are connected to each other. The lower cavity is located at the top of the first cotton layer, the through cavity passes through both the top and bottom ends of the second cotton layer, and the upper cavity is located at the bottom end of the third cotton layer. The first spring is pressed tightly against the lower cavity, the second spring is pressed tightly against the through cavity, and the third spring is pressed tightly against the upper cavity. The spring constants of the first spring, the second spring, and the third spring decrease sequentially.

[0005] As a preferred embodiment of this invention, the elastic support component is provided in multiple sets and is evenly distributed within the cotton body.

[0006] In a preferred embodiment of this utility model, the first spring, the second spring, and the third spring are all cylindrical helical springs.

[0007] As a preferred embodiment of the present invention, a support layer is respectively attached and fixed between the first cotton layer and the second cotton layer, and between the second cotton layer and the third cotton layer.

[0008] As a preferred embodiment of this invention, the support layer is a nylon mesh layer.

[0009] The beneficial effects of this utility model are as follows: The deformation of the first, second, and third springs drives the synchronous deformation of the first, second, and third cotton layers, thereby improving resilience. Furthermore, the spring constants of the first, second, and third springs decrease sequentially, corresponding to the sequential increase in softness of the first, second, and third cotton layers. This allows for one-to-one matching and deformation coordination, resulting in better overall comfort during rebound. Attached Figure Description

[0012] like Figure 1 As shown, this utility model proposes: a high-elasticity gradient composite memory foam, including a cotton body, the cotton body including a first cotton layer 1, a second cotton layer 2 and a third cotton layer 3 that are sequentially bonded and fixed from bottom to top, thereby forming a gradient composite memory foam; The softness of the first cotton layer 1, the second cotton layer 2, and the third cotton layer 3 increases sequentially; the third cotton layer 3 provides a good feel and comfort, while the firmer first cotton layer 1 and the second cotton layer 2 below provide sufficient support, better adapt to the curves of the human body, reduce pressure, and improve comfort; and the first cotton layer 1 and the second cotton layer 2 use memory foam material with high firmness, which can provide strong support for the body. It also includes a projectile-assisting component 4, which includes a first spring 41, a second spring 42 and a third spring 43 fixed from bottom to top, and a lower cavity 44, a through cavity 45 and an upper cavity 46 connected in series. The lower cavity 44 is located at the top of the first cotton layer 1, the through cavity 45 penetrates the top and bottom ends of the second cotton layer 2, and the upper cavity 46 is located at the bottom end of the third cotton layer 3. The first spring 41 is pressed tightly against the lower cavity 44, the second spring 42 is pressed tightly against the through cavity 45, and the third spring 43 is pressed tightly against the upper cavity 46. The spring constants of the first spring 41, the second spring 42, and the third spring 43 decrease sequentially. The three regions of the first cotton layer 1, the second cotton layer 2, and the third cotton layer 3 are respectively provided with a lower cavity 44, a through cavity 45, and an upper cavity 46 to provide space for the first spring 41, the second spring 42, and the third spring 43 to be placed in them respectively. The fitting position can be fixed by adhesive connection. The deformation of the first spring 41, the second spring 42, and the third spring 43 will drive the synchronous deformation of the first cotton layer 1, the second cotton layer 2, and the third cotton layer 3 respectively, thereby improving the resilience. Furthermore, the deformation of the first spring 41, the second spring 42, and the third spring 43 under the same force is different, which corresponds to the increasing softness of the first cotton layer 1, the second cotton layer 2, and the third cotton layer 3. They can be used in a one-to-one correspondence to coordinate deformation (e.g., the third spring 43 with larger deformation drives the softer third cotton layer 3 to deform), which also improves the overall comfort during rebound. Spring constant: the degree of deformation of the first spring 41, the second spring 42 and the third spring 43 when subjected to external force.

[0013] Among them, the elastic support component 4 is provided in multiple sets and is evenly distributed in the cotton body, with reasonable positions to improve the overall comfort when applying pressure.

[0014] Among them, the first spring 41, the second spring 42 and the third spring 43 are all cylindrical helical springs, which provide a rebound effect after compression deformation. The lower cavity 44, the through cavity 45 and the upper cavity 46 are fixed by the outer periphery of the cylindrical helical spring. At this time, under the compression deformation of the cylindrical helical spring, the first cotton layer 1, the second cotton layer 2 or the third cotton layer 3 can be driven to deform evenly, and the overall rebound stability is good.

[0015] Among them, the first cotton layer 1 and the second cotton layer 2, and the second cotton layer 2 and the third cotton layer 3 are respectively bonded and fixed with a surface support layer 5; the surface support layer 5 is a nylon mesh layer, which serves as an intermediate connecting layer to fix the first cotton layer 1 and the second cotton layer 2, and the second cotton layer 2 and the third cotton layer 3, thereby limiting the overall outward expansion deformation, providing a more vertical compression deformation, further improving stability, and protecting the first cotton layer 1, the second cotton layer 2 and the third cotton layer 3 from the deformation tension.

[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
