Description

Technical Field

[0001] The utility model relates to the technical field of sofa cushions, in particular to a slow-changing pressure sofa cushion. Background Art

[0002] Nowadays, sofas have become very popular in home life and office places. In order to improve the comfort of sofas, sofa cushions are generally placed on sofas.

[0003] Traditional sofa cushions are mostly composed of a surface fabric and internal fillers, and the elasticity of the sofa cushion is mainly controlled by the fillers. When sitting on the sofa cushion, the pressure on the buttocks is relatively fixed. Therefore, sitting on the sofa cushion for a long time will cause poor blood circulation and poor comfort. Content of the Utility Model

[0004] The utility model provides a slow-changing pressure sofa cushion to solve the above technical deficiencies. When sitting on it, the pressure values in different areas will slowly change, and the pressure change speeds in different areas are different.

[0005] The utility model discloses a slow-changing pressure sofa cushion, which includes a bottom cloth, a top cloth and a cushion core structure. The top cloth is arranged on the upper side of the bottom cloth, and the cushion core structure is arranged between the top cloth and the bottom cloth. The four sides of the top cloth and the bottom cloth are stitched and fixed. The cushion core structure includes a first plastic layer and a second plastic layer. The second plastic layer is located on the upper side of the first plastic layer. The first plastic layer and the second plastic layer are fixed by hot ironing. Uniformly arranged buffer cavities are formed between the first plastic layer and the second plastic layer. The front and rear buffer cavities are sequentially communicated through connecting channels, and from both sides to the middle direction, the width of the connecting channels connecting the buffer cavities gradually becomes larger. The buffer cavities are filled with liquid, and the filled liquid should ensure that there is no air residue in the buffer cavities and the filling amount is less than the full filling state.

[0006] When in use, when the buttocks sit on the rear side of the sofa cushion and the legs press on the front side of the sofa cushion, the pressure at the middle position of the buttocks is relatively large, the pressure at the edge position of the buttocks is relatively small, and the pressure on the legs is smaller compared to the pressure on the buttocks. Therefore, the liquid in the rear buffer cavity will be slowly squeezed into the front buffer cavity, and the pressure on the buttocks will slowly decrease. Since the width of the connecting channels connecting the buffer cavities gradually becomes larger from both sides to the middle direction, the pressure reduction speed at the middle position of the buttocks is greater than that at both sides of the buttocks. At this time, the force on the buttocks will slowly transfer from the middle to both sides. When the pressure at the middle position of the buttocks reaches the minimum, the liquid in the buffer cavity at the middle position of the buttocks will no longer be squeezed into the front buffer cavity, while the liquid in the buffer cavities on both sides of the buttocks is still being squeezed into the front buffer cavity. At this time, the force on the buttocks will slowly transfer from both sides to the middle, and finally the force is evenly distributed. The transfer of the force-bearing part of the buttocks during this period is beneficial to the blood circulation of the buttocks, and finally the overall force is evenly distributed.

[0007] Preferably, the buffer cavity is a rectangular buffer cavity, and the arrangement is more compact and flat.

[0008] Preferably, the buffer cavities are distributed in three rows and six columns. From both sides to the middle, the widths of the connecting channels connecting the buffer cavities are 0.5 mm, 0.75 mm, and 1 mm in sequence.

[0009] In order to be softer when sitting, a cotton layer is arranged between the cushion core structure and the top cloth.

[0010] For a variable-pressure sofa cushion obtained by the present utility model, the beneficial effects are as follows: when sitting on it, the liquid in the rear buffer cavity will be slowly squeezed into the front buffer cavity, the pressure on the buttocks will slowly decrease, and the force on the buttocks will slowly transfer from the middle to both sides and then from both sides to the middle, and finally the force is evenly distributed. During this period, the transfer of the force-bearing part on the buttocks is beneficial to the blood circulation of the buttocks. Description of the Drawings

[0015] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to describe in detail the specific implementation manners, structures, features, and effects according to the present utility model as follows.

[0016] Embodiment 1:

[0017] As Figures 1 to 4As shown in the figure, the utility model discloses a slow-changing pressure sofa cushion, which comprises a bottom cloth 2, a top cloth 1 and a cushion core structure. The top cloth 1 is arranged on the upper side of the bottom cloth 2, and the cushion core structure is arranged between the top cloth 1 and the bottom cloth 2. The peripheries of the top cloth 1 and the bottom cloth 2 are stitched and fixed. The cushion core structure comprises a first plastic layer and a second plastic layer. The second plastic layer is located on the upper side of the first plastic layer. The first plastic layer and the second plastic layer are fixed by hot ironing. A rectangular buffer cavity 4 distributed in three rows and six columns is formed between the first plastic layer and the second plastic layer. The front and rear buffer cavities 4 are sequentially communicated through a connecting channel 5. And from both sides to the middle direction, the widths of the connecting channels 5 connecting the buffer cavities 4 are 0.5 mm, 0.75 mm and 1 mm in sequence. The buffer cavity 4 is filled with liquid. The filled liquid should make there be no air residue in the buffer cavity 4 and the filling amount is less than the full filling state. A cotton layer 3 is arranged between the cushion core structure and the top cloth 1.

[0018] When in use, when the buttocks sit on the rear side of the sofa cushion and the legs press on the front side of the sofa cushion, the pressure at the middle position of the buttocks is relatively large, the pressure at the edge position of the buttocks is relatively small, and the pressure of the legs is even smaller compared with the pressure of the buttocks. Therefore, the liquid in the rear buffer cavity 4 will be slowly squeezed into the front buffer cavity 4, and the pressure of the buttocks will slowly decrease. Since the width of the connecting channel 5 connecting the buffer cavities 4 gradually increases from both sides to the middle direction, the speed of the pressure decrease at the middle position of the buttocks is greater than the speed of the pressure decrease at both sides of the buttocks. At this time, the force on the buttocks will slowly transfer from the middle to both sides. When the pressure at the middle position of the buttocks reaches the minimum, the liquid in the buffer cavity 4 at the middle position of the buttocks will no longer be squeezed into the front buffer cavity 4, while the liquid in the buffer cavities 4 at both sides of the buttocks is still being squeezed into the front buffer cavity 4. At this time, the force on the buttocks will slowly transfer from both sides to the middle, and finally the force is evenly distributed. During this period, the transfer of the force-bearing part of the buttocks is beneficial to the blood circulation of the buttocks, and finally the overall force is evenly distributed.
