Description

Technical Field

[0001] This invention belongs to the field of inflatable pad technology, specifically relating to an inflatable pad with a reflective film. Background Technology

[0002] An inflatable mattress generally refers to an inflated air mattress that can be used with a tent to provide a sleeping place during outdoor activities. Current inflatable mattresses often require an aluminum bubble mattress for insulation. However, carrying both an aluminum bubble mattress and an inflatable mattress during outdoor activities often takes up a lot of space in a vehicle, and the smooth surface of the aluminum bubble mattress can easily cause slippage during use, affecting the user experience and insulation effectiveness.

[0003] Therefore, it is necessary to design a structure that combines the functions of bubble aluminum pads and inflatable pads. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this solution provides an inflatable cushion with a reflective film.

[0005] The technical solution adopted in this invention is as follows:

[0006] An inflatable pad with a reflective film includes an upper layer, a lower layer, an upper hot-melt film, and an upper reflective film. The edges of the upper layer and the lower layer are hot-melt connected together, forming an inflation cavity between the upper and lower layers. The upper hot-melt film is hot-melt welded to the inner surface of the upper layer, forming several strip-shaped first interlayer spaces between them. Several strip-shaped upper reflective films are disposed within the first interlayer spaces. Several strip-shaped baffle membranes are disposed within the inflation cavity. The baffle membranes divide the inflation cavity into several strip-shaped compartments, with the upper reflective film located above the corresponding compartment.

[0007] As an alternative structure or supplementary design for the above-mentioned inflatable pad: a first welding line is formed at the welding point between the upper hot melt film and the upper layer; the upper edge of the baffle diaphragm is hot melt connected to the first welding line, and the first welding line is pulled towards the inside of the inflation cavity.

[0008] As an alternative structure or supplementary design for the above-mentioned inflatable cushion: the upper edge of the baffle diaphragm is bent to form a first bent edge, and the first bent edge is hot-melted and welded to the upper hot-melt film; at both ends of the upper reflective film, the upper hot-melt film and the upper surface layer are hot-melted and welded to form a first fixed weld point.

[0009] As an alternative structure or supplementary design for the above-mentioned inflatable pad: no upper hot melt film and upper reflective film are provided above the cavity near the perimeter of the upper layer.

[0010] As an alternative structure or supplementary design for the above-mentioned inflatable pad: the inflatable pad also includes a lower hot melt film and a lower reflective film; the lower hot melt film is hot melt welded to the inner surface of the lower layer, and forms several strip-shaped second interlayer spaces between the two, and several strip-shaped lower reflective films are disposed in the second interlayer spaces.

[0011] As an alternative structure or supplementary design for the above-mentioned inflatable pad: a second welding line is formed at the weld between the lower hot melt film and the lower layer; the lower edge of the baffle diaphragm is hot melt connected to the second welding line, and the second welding line is pulled towards the inside of the inflation cavity.

[0012] As an alternative structure or supplementary design for the above-mentioned inflatable cushion: the lower edge of the baffle diaphragm is bent to form a second bent edge, and the second bent edge is hot-melted and welded to the lower hot-melt film; at both ends of the lower reflective film, the lower hot-melt film and the lower layer are hot-melted and welded to form a second fixed weld point.

[0013] As an alternative structure or supplementary design for the above-mentioned inflatable pad: no upper hot melt film and upper reflective film are provided above the cavity near the perimeter of the upper layer.

[0014] As an alternative structure or supplementary design for the above-mentioned inflatable pad: both the upper and lower reflective films are made of aluminum film, non-woven fabric-based reflective film, or glass reflective film.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. In this solution, a reflective film is installed on the inner layer of the inflatable pad. This allows the heat radiation generated by the human body to be reflected by the reflective film when the inflatable pad is in use, thereby improving the heat preservation effect. At the same time, since the reflective film is embedded inside the inflatable pad, there is no need to carry an extra bubble aluminum pad when going outdoors, reducing the burden of carrying materials when traveling.

[0017] 2. In this solution, the reflective film is cut into several strip structures, with fixed welding points at both ends and welding lines on both sides, which enables a higher fault tolerance rate when the surface layer, reflective film, and hot melt film are misaligned; effectively reducing the difficulty of manufacturing inflatable cushions.

[0024] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, this embodiment designs an inflatable pad with a reflective film, including an upper layer 1, a lower layer 5, an upper hot melt film 3, an upper reflective film 2, a lower hot melt film 7, and a lower reflective film 6.

[0027] Both the upper layer 1 and the lower layer 5 are made of airtight and heat-fusible fabric, or they can be made of airtight fabric with an internal heat-fusible coating. The edges of the upper layer 1 and the lower layer 5 are heat-fusibly connected, forming an inflation cavity between them. When sufficient air is filled into the cavity, the upper layer 1 inflates upwards, facilitating sleeping and resting for the user. An inflation valve for inflating the cavity and a deflation valve for releasing air from the cavity can be heat-fused onto either the upper layer 1 or the lower layer 5. Existing structures can be used for the inflation and deflation valves, which will not be detailed here.

[0028] The upper hot-melt film 3 is hot-melt welded to the inner surface of the upper layer 1, forming several strip-shaped first interlayer spaces between them; several strip-shaped upper reflective films 2 are disposed within the first interlayer spaces; several strip-shaped baffle diaphragms 4 are disposed within the inflation cavity; the baffle diaphragms 4 divide the inflation cavity into several strip-shaped compartments, each compartment being interconnected at its end, or each baffle diaphragm 4 having through holes to allow interconnection between the compartments. The upper reflective film 2 is located above the corresponding compartment, and since the upper layer 1 arches upwards above the compartment when the inflation cavity is inflated, the middle parts of the upper reflective film 2 and the upper hot-melt film 3 also arch upwards, with the upper reflective film 2 located on the inner arc side of the upper layer 1.

[0029] A first welding line is formed at the weld between the upper hot melt film 3 and the upper layer 1; the upper edge of the baffle diaphragm 4 is hot melt connected to the first welding line and pulls the first welding line toward the inside of the inflation cavity; at both ends of the upper reflective film 2, the upper hot melt film 3 and the upper layer 1 are hot melt welded to form a first fixed weld point, which is located on the outer side of the end of the upper reflective film 2, and the first fixed weld points at both ends of the upper reflective film 2 confine the upper reflective film 2 between the two.

[0030] The upper edge of the baffle diaphragm 4 is bent to form a first bent edge, which is hot-melted and welded to the upper hot-melt film 3. The first bent edge can increase the contact area between the baffle diaphragm 4 and the upper hot-melt film 3, thereby improving the connection strength between the two. In addition, since the upper hot-melt film 3 above the cavity is arched when it is in the inflation state, the bending angle between the first bent edge and the baffle diaphragm 4 is greater than 90°.

[0031] The upper hot melt film 3 and the upper reflective film 2 may not be installed above the cavity at the edge of the upper layer 1.

[0032] The lower hot-melt film 7 is hot-melt welded to the inner surface of the lower layer 5, forming several strip-shaped second interlayer spaces between them. Several strip-shaped lower reflective films 6 are disposed within the second interlayer spaces. The lower reflective films 6 can effectively block cold air from under the inflatable pad, thereby further ensuring the heat preservation effect of the inflatable pad.

[0033] A second weld line is formed at the weld between the lower hot melt film 7 and the lower layer 5; the lower edge of the baffle diaphragm 4 is hot-melted and connected to the second weld line, and the second weld line is pulled towards the inside of the inflation cavity. At both ends of the lower reflective film 6, the lower hot melt film and the lower layer 5 are hot-melted and welded to form a second fixed weld point. The second fixed weld point is located on the outer side of the end of the lower reflective film 6, and the second fixed weld points at both ends of the lower reflective film 2 confine the lower reflective film 2 between the two.

[0034] The lower edge of the baffle diaphragm 4 is bent to form a second bent edge, which is then hot-melt welded to the lower hot-melt film 7. The lower hot-melt film 7 and the lower reflective film 6 are not disposed below the cavity near the perimeter of the lower layer 5. Both the upper reflective film 2 and the lower reflective film 6 are made of aluminum film, non-woven fabric-based reflective film, or glass reflective film.

[0035] In this embodiment, the upper reflective film 2 and the lower reflective film 6, which are set in the inner layer of the inflatable pad, can effectively replace the aluminum bubble pad and ensure the heat preservation effect, reducing the burden of carrying materials when traveling. The reflective film is cut into several strip structures, with its two ends limited by fixed welding points and the two sides limited by welding lines, so that the surface layer, reflective film and hot melt film have a higher fault tolerance rate when misalignment occurs; effectively reducing the difficulty of manufacturing the inflatable pad.

[0036] Example 2

[0037] The manufacturing method of the inflatable cushion described in Example 1 includes the following steps:

[0038] S1: Cut the raw material of the reflective film to form an upper reflective film 2 and a lower reflective film 6 of a specified size;

[0039] S2: The upper layer 1, the upper reflective film 2 and the upper hot melt film 3 are stacked and laid flat on the operating table. At the outer ends of the upper reflective film 2, the upper hot melt film 3 and the upper layer 1 are hot melt welded to form the first fixed weld point, and the upper reflective film 2 is limited by the two first fixed weld points.

[0040] S3: Lay the lower layer 5, the lower reflective film 6 and the lower hot melt film 7 on the operating table in sequence. At the outer ends of the lower reflective film 6, heat melt the lower hot melt film 7 and the lower layer 5 to form a second fixed weld point, and use the two second fixed weld points to limit the position of the lower reflective film 2.

[0041] S4: The bent portion of the upper edge of the baffle diaphragm 4, the upper layer 1 and the upper reflective film 2 are heat-melted and welded together to form a first weld line; the bent portion of the lower edge of the baffle diaphragm 4, the lower layer 5 and the lower reflective film 6 are heat-melted and welded together to form a second weld line;

[0042] S5: Finally, the outer periphery of the upper layer 1 and the lower layer 5 are heat-fused together to form a complete and closed air-filled cavity.

[0043] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
