Description

Technical Field

[0001] This utility model belongs to the field of inflatable cushion technology, specifically relating to a sponge inflatable cushion with an added reflective film. Background Technology

[0002] Traditional inflatable foam mattresses typically consist of a single sheet of foam bonded to a bottom layer material to form a stable, sealed structure. When in use, the mattress is inflated to create a full foam cavity. However, this simple foam cavity structure, when used outdoors, relies solely on the foam to insulate against the body's heat radiation and the cold air from the ground. The foam's porous nature allows for strong convection currents within the cavity, leading to significant heat loss.

[0003] In order to reduce the convection of hot and cold air inside the inflatable product, thereby reducing heat loss and improving the product's heat insulation performance, it is necessary to design an inflatable pad with built-in sponge containing reflective material. Utility Model Content

[0023] 1. This solution uses multiple layers of sponge and adds a reflective film between the sponges, thereby using the reflective film to block the heat radiation from the human body, thus improving the product's heat preservation effect;

[0024] 2. Due to the low weight of the reflective film, its weight accounts for only 2.5%-4% of the entire inflatable pad, which will not have a significant impact on the overall weight of the inflatable pad and has little impact on portability, but significantly improves the warmth retention effect.

[0025] 3. The thickness of the reflective film is 20um±1um, which will not significantly affect the thickness of the inflatable pad;

[0044] The composite filler includes two layers of sponge 2, namely a first sponge 2A and a second sponge 2B; the thickness of the first sponge 2A is less than the thickness of the second sponge 2B, and the sponges 2 overlap vertically; a reflective film 3 is provided between adjacent layers of sponge 2, and the two sides of the reflective film 3 are fused to the corresponding sponge 2; the upper surface of the composite filler is fused to the top fabric 1, and the lower surface of the composite filler is fused to the bottom fabric 5.

[0045] A reflective film 3 can be provided above the uppermost sponge 2 (i.e., the first sponge 2A) of the combined filling body, and a reflective film 3 can be provided below the lowermost sponge 2 (i.e., the second sponge 2B) of the combined filling body. By increasing the number of reflective films 3, the heat reflection and heat blocking effect can be improved, and the convection of air between different layers of sponge 2 can be reduced.

[0046] The reflective film 3 is a thin film with a metal coating. The reflective film 3 can be an aluminum-coated film (such as aluminum-coated non-woven fabric). TPU coating, PVC coating or adhesive coating are provided on both sides of the reflective film 3. The adhesive can be an existing product that can bond the reflective film 3 to the sponge 2. The top fabric 1 and the bottom fabric 5 are made of fabric, TPU film or PVC film. When the top fabric 1 and the bottom fabric 5 are fabric, TPU coating or PVC coating is provided on the side of the top fabric 1 and the bottom fabric 5 facing the sponge 2.

[0047] Example 2

[0048] like Figure 2 As shown, based on Embodiment 1, the production line for the inflatable cushion body includes a material preparation area, a welding area, a cooling area, and an edge sealing area. The material preparation area is used to place rolls of top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B, and reflective film 3. The welding area is equipped with two heating and pressurizing devices, one above the other, for hot-melt welding of the overlapping top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B, and reflective film 3. The cooling area has a cooling box, where the top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B, and reflective film 3 are cooled by air after being welded. The edge sealing area has an outer frame mold, where the top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B, and reflective film 3 are cut and placed into the outer frame mold to facilitate welding the edges of the top fabric 1 to the edges of the bottom fabric 5.

[0049] The manufacturing process of the inflatable cushion body includes the following steps:

[0050] Material preparation: Place the rolls of top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B and reflective film 3 into the material preparation area, and extend the ends of the rolls.

[0051] Welding: After the top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B and reflective film 3 are led out, they pass between two heating and pressurizing devices and achieve hot melt welding;

[0052] Cooling: The part of the top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B and reflective film 3 after being fused together is introduced into the cooling box and cooled by the cold air flow in the cooling box.

[0053] Edge sealing: Place the cut portions of top fabric 1, bottom fabric 5, first sponge 2A, second sponge 2B and reflective film 3 into the outer frame mold, and manually weld the edges of the top fabric 1 to the edges of the bottom fabric 5.

[0054] Example 3

[0055] Based on the structure of Example 1, such as Figure 1 , 4 As shown in Figures 6 and 7, the second sponge 2B has a horizontal hole 6 that penetrates the second sponge 2B horizontally. By creating a hole in the second sponge 2B, the weight of the second sponge 2B can be effectively reduced, thereby reducing the overall weight of the inflatable pad.

[0056] A filling strip, such as a down strip 8, can be provided inside the horizontal hole 6. Figure 6 As shown, the filling strip can be a cotton strip 9, such as... Figure 7 As shown.

[0057] In addition, several vertical holes are provided on the first sponge 2A, such as...

[0062] A reflective film 3 can be provided above the uppermost sponge 2 (i.e., the first sponge 2A) of the combined filling body, and a reflective film 3 can be provided below the lowermost sponge 2 (i.e., the third sponge 2C) of the combined filling body, thereby increasing the amount of heat reflection and heat blocking effect by increasing the number of reflective films 3.

[0063] The reflective film 3 is a thin film with a metal coating. The reflective film 3 can be an aluminum-coated film (such as aluminum-coated non-woven fabric). TPU coating, PVC coating or adhesive coating are provided on both sides of the reflective film 3. The top fabric 1 and the bottom fabric 5 are made of fabric, TPU film or PVC film. When the top fabric 1 and the bottom fabric 5 are fabrics, TPU coating or PVC coating is provided on the side of the top fabric 1 and the bottom fabric 5 facing the sponge 2.

Figure 11 (As shown).

[0068] The reflective film 3 is a thin film with a metal coating, and TPU coating, PVC coating, or adhesive coating are provided on both sides of the reflective film 3; the reflective strip 7 adopts the same structure as the reflective film 3; the top fabric 1 and the bottom fabric 5 are made of fabric, TPU film, or PVC film. When the top fabric 1 and the bottom fabric 5 are fabric, a TPU coating or PVC coating is provided on the side of the top fabric 1 and the bottom fabric 5 facing the sponge 2.
