Description

A multi-layer reflective heat insulation film inflatable cushion Technical Field

[0001] The utility model belongs to the technical field of inflatable cushions, and in particular relates to a multi-layer reflective heat-insulating film type inflatable cushion. Background Art

[0002] In the existing inflatable mattress structure, the inflatable bed with an aluminum-plated film has an integral internal baffle, and the upper and lower sides of the baffle are respectively connected to the upper and lower inner walls of the airbag cavity, while the aluminum-plated film can only be fixed to the upper and lower inner walls of the airbag cavity. Since the product form of the inflatable bed is achieved through the concave and convex shape of the inner wall of the airbag cavity, different product forms of the inflatable bed often require the design of special production steps to adapt to the position of the aluminum-plated film.

[0003] The patented technology with patent number CN116616580A discloses an inflatable cushion with a reflective insulation film. The reflective insulation film is arranged at the center of the airbag cavity of the inflatable cushion. Therefore, when the surface of the inflatable cushion product is shaped, there is no need to consider the position of the reflective insulation film. Only the position of the baffle needs to be designed. In this way, inflatable cushion products with different surface shapes can have more unified production steps, simplify production and improve production efficiency.

[0004] However, in this patented technology, when n layers of multi-layer reflective insulation film are set, n-1 layers of baffles are often also required. This will produce more welding connection points, consume a large number of baffles, generate a lot of manpower loss and cost, and affect production efficiency.

Modes for Carrying Out the Invention

[0026] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.

[0027] Example 1

[0028] As shown in Figures 1 to 4, this embodiment designs a multi-layer reflective insulation film inflatable cushion, which includes an upper layer 1 and a lower layer 9. The outer peripheries of the upper layer 1 and the lower layer 9 are directly welded together or welded together through a surrounding cloth, thereby forming an airbag cavity inside the inflatable cushion.

[0029] A vertical partition and a reflective heat-insulating auxiliary film are provided in the airbag cavity of the inflatable cushion; the upper side of the vertical partition is welded to the upper layer 1 of the inflatable cushion, and the lower side of the vertical partition is welded to the lower layer 9 of the inflatable cushion; a plurality of vertical partitions divide the airbag cavity into a plurality of transversely arranged compartments.

[0030] The vertical partitions include one or more baffles, each equipped with a plurality of protruding teeth. The reflective insulation secondary film is provided with through-holes 10, through which the protruding teeth pass, placing the reflective insulation secondary film in the center of the corresponding baffle. By placing the reflective insulation secondary film on the protruding teeth, the number of baffles used can be reduced, thereby reducing labor and costs associated with welding and processing the baffles, thereby improving production efficiency. This also facilitates the use of more reflective insulation film, thereby enhancing the reflective insulation effect.

[0031] An upper reflective insulation film 2 is disposed between the upper side of the vertical baffle and the upper layer 1. When the upper reflective insulation film 2 is made of a material that is not heat-melt-weldable, a through hole 10 is provided in the upper reflective insulation film 2. The upper side of the vertical baffle is welded to the upper layer 1 at the through hole 10 of the upper reflective insulation film 2. When the upper reflective insulation film 2 is made of a material that is heat-melt-weldable, the upper side of the vertical baffle is directly welded to the upper layer 1 and the upper reflective insulation film 2. A lower reflective insulation film 6 is disposed between the lower side of the vertical baffle and the lower layer 9. When the lower reflective insulation film 6 is made of a material that is not heat-melt-weldable, a through hole 10 is provided in the lower reflective insulation film 6. The lower side of the vertical baffle is welded to the lower layer 9 at the through hole 10 of the lower reflective insulation film 6. When the lower reflective insulation film 6 is made of a material that is heat-melt-weldable, the lower side of the vertical baffle is directly welded to the lower layer 9 and the lower reflective insulation film 6.

[0032] When the vertical partition includes multiple baffles, an intermediate reflective insulation film 4 is arranged between two vertically adjacent baffles. When the intermediate reflective insulation film 4 is made of a material that cannot be hot-melt welded, the intermediate reflective insulation film 4 is provided with a through hole 10, and the adjacent baffles are welded together at the through hole 10 of the intermediate reflective insulation film 4; when the intermediate reflective insulation film 4 is made of a material that can be hot-melt welded, the adjacent baffles are directly welded to the intermediate reflective insulation film 4.

[0033] When the upper reflective insulation film 2, the lower reflective insulation film 6, the intermediate reflective insulation film 4, etc. are made of materials that can be hot-melt welded, materials such as aluminum-plated non-woven fabrics can be selected; when the upper reflective insulation film 2, the lower reflective insulation film 6, the intermediate reflective insulation film 4, etc. are made of materials that cannot be hot-melt welded, materials such as PET aluminum-plated film can be selected.

[0034] When the vertical partition includes two baffles:

[0035] The two baffles are an upper baffle 7 and a lower baffle 8, the tips of the convex teeth of the upper baffle 7 are facing upward, and the tips of the convex teeth of the lower baffle 8 are facing downward; the reflective heat insulation sub-film includes an upper reflective heat insulation sub-film 3 and a lower reflective heat insulation sub-film 5; the upper reflective heat insulation sub-film 3 is placed in the middle of the upper baffle 7, and the lower reflective heat insulation sub-film 5 is placed in the middle of the lower baffle 8.

[0036] Both the upper baffle 7 and the lower baffle 8 have a first folded edge 11 and a second folded edge 12; the first folded edge 11 is located at the tooth tip of the convex tooth, and the second folded edge 12 is located on the side of the baffle away from the convex tooth; the first folded edge 11 is used for welding connection with the adjacent baffle, the upper layer 1 or the lower layer 9, and the second folded edge 12 is used for welding connection with the adjacent baffle, the upper layer 1 or the lower layer 9.

[0037] The second folded edge 12 of the upper baffle 7 and the second folded edge 12 of the lower baffle 8 are welded together at the through hole 10 of the middle reflective insulation film 4, the convex teeth of the upper baffle 7 pass through the through hole 10 of the upper reflective insulation auxiliary film 3, and the first folded edge 11 of the upper baffle 7 is welded together with the upper layer 1 at the through hole 10 of the upper reflective insulation film 2; the convex teeth of the lower baffle 8 pass through the through hole 10 of the lower reflective insulation auxiliary film 5, and the first folded edge 11 of the lower baffle 8 and the lower layer 9 are welded together at the through hole 10 of the lower reflective insulation film 6.

[0038] The protruding teeth can be trapezoidal, with the short sides facing outward. The through-holes 10 in the upper and lower reflective insulation films 3 and 5 fit snugly into the waist of the trapezoidal teeth. When the same trapezoidal protruding teeth connect multiple layers of reflective insulation films, films with different through-hole lengths are attached at different heights in the middle of the protruding teeth. The through-hole lengths of the reflective insulation films can be varied to adjust their position on the baffle, further increasing the number of reflective insulation films. Space between adjacent reflective insulation films is required to reduce thermal radiation, convection, and overall insulation performance.

[0039] When the upper reflective insulation film 2 is provided on the lower side of the upper layer 1, a portion of the first folded edge 11 abuts against the edge of the through hole 10 of the upper reflective insulation film 2. When the lower reflective insulation film 6 is provided on the upper side of the lower layer 9, a portion of the first folded edge 11 at the convex tooth tip of the lower baffle 8 abuts against the edge of the through hole 10 of the lower reflective insulation film 6.

[0040] In addition, it should be noted that multiple baffles are provided in the length direction or width direction of the inflatable cushion.

[0041] The above embodiments are merely examples for the purpose of illustrating the present invention clearly and are not intended to limit the embodiments. It is not necessary and impossible to enumerate all embodiments here. Obvious changes or modifications derived therefrom are still within the scope of protection of this technology.
