Description

Technical Field

[0001] This utility model relates to the field of sponge pad technology, and more specifically to a breathable porous composite sponge pad. Background Technology

[0002] Sponge pads are a common type of soft filling material, usually made of polyurethane foam or similar materials. They have good elasticity and shock absorption, and can provide comfortable support and cushioning. They can be used in furniture such as sofas, chairs, and mattresses to increase comfort when sitting or lying down.

[0003] The existing sponge pads, as shown in application number CN202421681906.X, "A High-Elastic Latex Sponge Pad", improve breathability by opening through holes in the upper and lower sponge pads, and allow air to pass through the vents on the silicone block.

[0004] The aforementioned high-elastic latex sponge pad, although it can be breathed from top to side through ventilation channels to improve heat conduction and dissipation, has the disadvantage of poor breathability due to possible pore blockage caused by deformation (especially when pressure is applied to one position for a long time) when using soft sponge materials designed to provide comfort. Utility Model Content

[0005] The purpose of this utility model is to provide a breathable porous composite sponge pad in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes a breathable porous composite sponge pad, including a pad body and a heat dissipation cavity provided thereon. The top and bottom ends of the pad body are respectively attached and fixed with a surface layer, and the top of the pad body is connected to the outer periphery of the pad body through the heat dissipation cavity.

[0008] It also includes a bamboo charcoal fiber filling layer located inside the heat dissipation cavity;

[0009] The surface layer is breathable and is made of ice silk fiber.

[0010] As a preferred technical solution of this utility model, it also includes a fixed edge layer that is attached and fixed to the outer periphery of the pad body, and the fixed edge layer is breathable.

[0011] In a preferred embodiment of this invention, the edge-fixing layer is a polyester fiber layer.

[0012] As a preferred technical solution of this utility model, the pad body includes an upper sponge layer and a lower sponge layer arranged vertically, and a supporting sponge layer that is adhered and fixed between the upper sponge layer and the lower sponge layer;

[0013] The heat dissipation cavity includes multiple sets of through holes evenly distributed at the top of the upper sponge layer and an inner cavity provided on the supporting sponge layer.

[0014] Multiple sets of through holes penetrate the bottom of the upper sponge layer, and the outer periphery of the supporting sponge layer is connected to the multiple sets of through holes through the inner cavity. The top of the upper sponge layer and the bottom of the lower sponge layer are respectively attached to the fixed surface layer.

[0015] As a preferred embodiment of this invention, the softness of the supporting layer is less than that of the upper and lower sponge layers.

[0016] As a preferred technical solution of this utility model, the supporting cotton layer includes an upper interlayer and a lower interlayer that are fixed together. A grid cavity is formed between the upper interlayer and the lower interlayer. The top of the upper interlayer is provided with a connecting hole that communicates with the grid cavity. There are multiple sets of connecting holes, and each of them corresponds to and communicates with a series of through holes. The multiple sets of connecting holes and the grid cavity constitute an inner cavity.

[0017] As a preferred technical solution of this utility model, the supporting layer further includes multiple sets of inserts at the top of the upper interlayer and multiple sets of slots that correspond one-to-one for inserting the multiple sets of inserts. The multiple sets of slots are located at the bottom of the upper sponge layer, and the multiple sets of inserts are located one-to-one at the top of the multiple sets of connecting holes, with the connecting holes penetrating the inserts.

[0018] As a preferred embodiment of this invention, the supporting layer further includes a filling layer, which is a bamboo charcoal fiber filling layer.

[0019] The beneficial effects of this utility model are as follows:

[0020] By inserting the bamboo charcoal fiber filling layer into the heat dissipation cavity, a certain degree of support can be provided to increase the stability of the heat dissipation cavity under pressure, thereby enhancing breathability and heat dissipation. The bamboo charcoal fiber filling layer can also provide moisture absorption and perspiration wicking function and has a certain degree of thermal conductivity, which can promote the diffusion and dissipation of heat. The solid surface layer, which is made of ice silk fiber layer or linen fiber layer, provides thermal conductivity to transfer heat to the bamboo charcoal fiber filling layer and has good moisture absorption and perspiration wicking performance, which can improve the coolness to the touch.

[0026] like Figures 1-4 As shown, this utility model proposes: a breathable porous composite sponge pad, including a pad body and a heat dissipation cavity provided thereon, with a solid surface layer 5 respectively attached and fixed at the top and bottom ends of the pad body, and the top of the pad body communicating with the outer periphery of the pad body through the heat dissipation cavity;

[0027] It also includes a bamboo charcoal fiber filling layer inside the heat dissipation cavity; after the bamboo charcoal fiber filling layer is placed into the heat dissipation cavity, it can provide a certain support to increase the stability of the heat dissipation cavity under pressure, and enhance the temperature of air permeability.

[0028] Meanwhile, the bamboo charcoal fiber filling layer has excellent moisture absorption and perspiration wicking properties, which can absorb odors; the bamboo charcoal fiber filling layer itself has a certain degree of thermal conductivity, which can promote the diffusion and dissipation of heat.

[0029] The surface layer 5 is breathable and is made of ice silk fiber or linen fiber, which has a cool touch and can improve the coolness and comfort during use, making the sponge pad more suitable for summer; the surface layer 5 can be fixed by spray adhesive.

[0030] It also includes a retaining layer 6 that is attached and fixed to the outer periphery of the pad. The retaining layer 6 is breathable. The retaining layer 6 can be fixed by spraying adhesive to protect the outer periphery of the pad.

[0031] Among them, the edge-fixing layer 6 is a polyester fiber layer, which has good durability.

[0032] Specifically: The pad body includes an upper sponge layer 1 and a lower sponge layer 2 arranged vertically, and a support sponge layer 3 that is attached and fixed between the upper sponge layer 1 and the lower sponge layer 2, that is, the upper sponge layer 1, the support sponge layer 3 and the lower sponge layer 2 are attached and fixed from top to bottom.

[0033] Specifically: The heat dissipation cavity includes multiple sets of through holes 4 evenly distributed at the top of the upper sponge layer 1 and an inner cavity provided on the supporting sponge layer 3;

[0034] Multiple sets of through holes 4 penetrate the bottom end of the upper sponge layer 1, and the outer periphery of the supporting sponge layer 3 is connected to the multiple sets of through holes 4 through the inner cavity. The top end of the upper sponge layer 1 and the bottom end of the lower sponge layer 2 are respectively attached to the fixed surface layer 5; that is, the inner cavity connects the outer periphery of the supporting sponge layer 3 and the top end of the supporting sponge layer 3 and is connected to the through hole 4 at the top end of the supporting sponge layer 3.

[0035] Among them, the softness of the supporting layer 3 is smaller than that of the upper sponge layer 1 and the lower sponge layer 2; that is, the supporting layer 3 can also be a sponge, but its density is greater than that of the upper sponge layer 1 and the lower sponge layer 2, which can provide better support to reduce the deformation of the inner cavity after being compressed.

[0036] The specific structure of the supporting layer 3 is shown below:

[0037] The supporting layer 3 includes an upper interlayer 31 and a lower interlayer 32 that are attached and fixed together. A mesh cavity 33 is formed between the upper interlayer 31 and the lower interlayer 32. The top of the upper interlayer 31 is provided with a connecting hole 34 that communicates with the mesh cavity 33. Multiple sets of connecting holes 34 are provided, and they are connected one-to-one with multiple sets of through holes 4. The multiple sets of connecting holes 34 and the mesh cavity 33 constitute the inner cavity. The mesh cavity 33 is used to allow air to pass through and to connect the front, back, left and right outer edges of the supporting layer 3. That is, the multiple sets of through holes 4 can provide communication in multiple directions around the supporting layer 3 to improve air permeability. Moreover, the structure of the upper interlayer 31 and the lower interlayer 32 being separated and connected as a whole facilitates the production of the inner cavity. The connection position can be fixed by spraying adhesive.

[0038] Furthermore, the supporting layer 3 also includes multiple sets of inserts 35 at the top of the upper interlayer 31 and multiple sets of slots 36 corresponding to each other for inserts 35 to fit into. The multiple sets of slots 36 are located at the bottom of the upper sponge layer 1, and the multiple sets of inserts 35 are located at the top of multiple sets of connecting holes 34, with the connecting holes 34 penetrating the inserts 35. The inserts 35 are fixed at the top of the upper interlayer 31 and at the position corresponding to the connecting holes 34 (the fixing method can be adhesive or integral formation). The slots 36 are set at the bottom of the upper sponge layer 1. This can improve the positional accuracy during assembly. In particular, the greater rigidity of the inserts 35 can reduce the deformation of the connecting holes 34 to better connect to the through holes 4, thereby improving the breathability stability.

[0039] Furthermore, the supporting layer 3 also includes a filling layer 37, which is a bamboo charcoal fiber filling layer; the filling layer 37 is located in the aforementioned mesh cavity 33, multiple sets of through holes 4 and multiple sets of connecting holes 34.

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.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
