Description

Technical Field

[0001] This utility model belongs to the field of air bed technology, specifically relating to an air bed with the function of reducing heat conduction. Background Technology

[0002] Inflatable mattresses are widely used in daily life due to their softness, lightness, ease of use, and small space occupation when folded up. However, inflatable mattresses have an air chamber, and the movement of air within this chamber can easily cause heat loss, resulting in poor insulation. When a person uses an inflatable mattress, some heat is directly dissipated through the surface of the mattress into the air inside the chamber, while the rest is dissipated through thermal radiation. Because conventional inflatable mattresses cannot effectively block heat conduction, they suffer from rapid heat loss and poor insulation during use. Therefore, it is necessary to design an inflatable mattress structure that can reduce heat conduction. Utility Model Content

[0006] A horizontal reflective cloth is provided inside the inflation chamber; the edges of the horizontal reflective cloth are fixedly connected to the side cloth; the horizontal reflective cloth has several perforations, and the vertical tie rod passes through the perforations.

[0007] The inflation chamber is also provided with an oblique reflective cloth, which is located above the horizontal reflective cloth and its surface is inclined to the horizontal reflective cloth; the lower edge of the oblique reflective cloth is fixedly connected to the horizontal reflective cloth, and the upper edge of the oblique reflective cloth is fixedly connected to the side cloth.

[0008] As an alternative or supplement to the above structure, the vertical tie rod is in the shape of a ring or a C.

[0009] As an alternative or supplement to the above structure: when the vertical tie rod is circular, the hollow hole is rectangular; when the vertical tie rod is C-shaped, the hollow hole is elongated.

[0010] As an alternative or supplement to the above structure: the oblique reflective fabric is long and narrow, and one oblique reflective fabric is provided around each of the four sides of the horizontal reflective fabric; the four oblique reflective fabrics are not connected to each other, or the four oblique reflective fabrics are connected end to end to form a square basin-shaped structure that is larger at the top and smaller at the bottom. As an alternative or supplement to the above structure: the parts that need to be fixedly connected between the top fabric, bottom fabric, side fabric, horizontal reflective fabric and oblique reflective fabric are all connected by welding.

[0011] As an alternative or supplement to the above structure: both the horizontal reflective fabric and the oblique reflective fabric are made of non-woven composite aluminum insulation fabric or non-woven composite cotton insulation fabric.

[0012] As an alternative or supplement to the above structure, its manufacturing process includes the following steps:

[0013] A: Lay the horizontal reflective fabric with perforations onto the welding platform, and place the oblique reflective fabric at the edge of the horizontal reflective fabric; weld the two together by hot pressing or high-frequency process, and weld the oblique lower edge of the oblique reflective fabric to the horizontal reflective fabric.

[0014] B: Lay the base fabric flat on the welding platform, and lay the horizontal reflective fabric welded in step A on top of the base fabric.

[0015] C: Pass the lower ends of several vertical tie rods through the perforations of the horizontal reflective fabric and weld them together with the base fabric;

[0016] D: Place the first mold above the horizontal reflective fabric after welding in step B, and place the annular side fabric inside the first mold; at the upper edge of the first mold, weld the side fabric together with the upper edge of the oblique reflective fabric; at the lower edge of the first mold, weld the side fabric together with the edge of the horizontal reflective fabric.

[0017] E: Replace the first mold with the second mold, which is taller, so that the upper edge of the side wall is placed at the upper edge of the second mold and the lower edge is placed at the lower edge of the second mold; place the top fabric above the second mold, and fix the upper end of the vertical tie rod to the top fabric; at the upper edge of the second mold, weld the upper edge of the side fabric to the upper edge of the top fabric together; at the lower edge of the second mold, weld the lower edge of the side fabric to the edge of the bottom fabric together.

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

[0020] 1. In this solution, the air chamber inside the air bed can be divided into upper and lower layers by using oblique and horizontal reflective cloths, which can slow down the air flow inside the air chamber, thereby reducing heat loss caused by air flow and thus reducing heat conduction efficiency.

They can reflect the heat generated by the human body in the form of heat radiation. Furthermore, the structure of the horizontal reflective fabric and the four oblique reflective fabrics together forms a basin-shaped structure, which allows the heat radiation to be concentrated in the middle of the mattress after reflection, further reducing heat conduction and improving heat preservation performance.

[0034] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the 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.

[0035] Example 1

[0036] like Figures 1 to 5 as well as Figure 10 As shown, this embodiment designs an air bed with heat conduction reduction function, including components such as top cloth 1, bottom cloth 2, side cloth 4, vertical tie rod 6, oblique reflective cloth 3, and horizontal reflective cloth 5.

[0037] The top fabric 1, side fabrics 4, and bottom fabric 2 are all rectangular, breathable fabrics, typically made of TPU-coated material. The top fabric 1 is positioned above the bottom fabric 2. The side fabrics 4 are connected between the edges of the top fabric 1 and the bottom fabric 2. The upper edge of the side fabric 4 is fused to the edge of the top fabric 1, and the lower edge of the side fabric 4 is fused to the edge of the bottom fabric 2. An air chamber is formed between the top fabric 1, bottom fabric 2, and side fabrics 4. An inflation nozzle is provided on the side fabric 4. After inflation into the air chamber through the inflation nozzle, the air bed expands for use.

[0038] Vertical tie rods 6 are installed inside the inflation chamber. The vertical tie rods 6 can be circular (as shown in the figure) or C-shaped (not shown in the figure). Several vertical tie rods 6 are distributed in a rectangular array inside the inflation chamber. The upper end of each vertical tie rod 6 is fixedly connected to the top fabric 1, and the lower end of each vertical tie rod 6 is fixedly connected to the bottom fabric 2. The vertical tie rods 6 can pull the top fabric 1 and the bottom fabric 2 closer together, thereby achieving the shaping of the air bed and the control of its height.

[0039] A horizontal reflective fabric 5 is installed inside the inflation chamber; the edges of the horizontal reflective fabric 5 are fixedly connected to the side fabric 4. The horizontal reflective fabric 5 not only divides the inflation chamber into upper and lower layers, slowing down the airflow within the inflation chamber, thereby mitigating heat loss caused by airflow and reducing heat conduction efficiency, but also, the horizontal reflective fabric 5 can be made of materials that reflect heat radiation, such as non-woven composite aluminum insulation fabric or non-woven composite cotton insulation fabric, which can reflect the heat generated by the human body in the form of thermal radiation, further reducing heat conduction and improving insulation performance.

[0040] Several perforations are provided on the horizontal reflective fabric 5 so that the vertical tie rod 6 can pass through the perforations; when the vertical tie rod 6 is circular, the perforations are rectangular, as shown in the figure; when the vertical tie rod 6 is C-shaped, the perforations are elongated, not shown in the figure.

[0041] The air-filled cavity also contains an oblique reflective fabric 3, which is positioned above the horizontal reflective fabric 5, with its surface inclined towards the horizontal reflective fabric 5. The lower edge of the oblique reflective fabric 3 is fixedly connected to the horizontal reflective fabric 5, and the upper edge of the oblique reflective fabric 3 is fixedly connected to the side fabric 4. The oblique reflective fabric 3 is made of non-woven composite aluminum insulation fabric or non-woven composite cotton insulation fabric, thus reflecting heat radiation. The horizontal reflective fabric 5 and the four oblique reflective fabrics 3 can cooperate to form a basin-shaped structure, allowing heat radiation to be concentrated in the center of the mattress after reflection, reducing heat conduction and improving insulation performance.

[0042] The oblique reflective cloth 3 is elongated, and one oblique reflective cloth 3 is arranged around each of the four sides of the horizontal reflective cloth 5; the four oblique reflective cloths 3 are not connected to each other, as shown in the figure (e.g.) Figure 3 , 4 As shown), or, four pieces of diagonally reflective fabric are connected end to end to form a square basin-shaped structure that is larger at the top and smaller at the bottom (as shown). Figure 9 (As shown). When the oblique reflective cloth 3 forms a square basin shape, the four corners of the oblique reflective cloth 3 have arc-shaped chamfers, and at the same time, the mouth end of the oblique reflective cloth 3 is larger than the bottom end.

[0043] All the parts that need to be fixedly connected among the above-mentioned top fabric 1, bottom fabric 2, side fabric 4, horizontal reflective fabric 5 and oblique reflective fabric 3 can be connected by welding.

[0044] In addition, since the four sides of the horizontal reflective cloth 5 are fixedly connected to the side cloth 4, while the side cloth 4 is used to tension the horizontal reflective cloth 5, the horizontal reflective cloth 5 also pulls the side cloth inward, thereby achieving the shaping of the side wall, reducing the degree of outward bulging of the side wall, improving the stability of the air bed, and reducing the shaking of the air bed during use.

[0045] Example 2

[0046] like Figures 1 to 8 As shown, the production process of the air-filled bed in Example 1 includes the following steps:

[0047] A: Lay the horizontal reflective fabric 5 with perforations onto the welding platform, and place the oblique reflective fabric 3 at the edge of the horizontal reflective fabric 5; weld the two together by hot pressing or high frequency process, and weld the oblique lower edge 31 of the oblique reflective fabric 3 to the horizontal reflective fabric 5.

[0048] B: Lay the base fabric 2 flat on the welding platform, and lay the horizontal reflective fabric 5 after welding in step A on top of the base fabric 2.

[0049] C: Pass the lower ends of several vertical tie rods 6 through the perforations of the horizontal reflective fabric 5 and weld them together with the base fabric 2;

[0050] D: Place the first mold 7 above the horizontal reflective fabric 5 welded in step B, and place the annular side fabric 4 inside the first mold 7, as follows. Figure 7 As shown; at the upper edge of the first mold 7, the side fabric 4 is fused together with the upper edge of the oblique reflective fabric 3; at the lower edge of the first mold 7, the side fabric 4 is fused together with the edge of the horizontal reflective fabric 5.

[0051] E: Replace the first mold 7 with the taller second mold 9, so that the upper edge of the sidewall is positioned at the upper edge of the second mold 9 and the lower edge is positioned at the lower edge of the second mold, as shown. Figure 8 As shown; place the top fabric 1 above the second mold 9, and fix the upper end of the vertical tie rod 6 to the top fabric 1 (weld); at the upper edge of the second mold 9, weld the upper edge of the side fabric 4 to the upper edge of the top fabric 1 together; at the lower edge of the second mold 9, weld the lower edge of the side fabric 4 to the edge of the bottom fabric 2 together.

[0052] F: Remove the second mold 9, install the air nozzle on the side fabric 4, and then trim the welded parts.

[0053] The first mold 7 can be adopted as follows: Figure 6 The structure shown has the following characteristics: the height of the first mold 7 is 0.3 to 0.5 times the height of the side fabric 4; the second mold 9 has the same structure as the first mold 7, but the height of the second mold 9 is 0.7 to 0.9 times the height of the side fabric 4.

[0054] 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.
