Description

Technical Field

[0001] The invention belongs to the technical field of air-filled beds, and in particular relates to an air-filled bed with a function of reducing heat conduction. Background Art

[0002] Inflatable beds are widely used in our daily lives due to their advantages such as being soft, lightweight, easy to use, and taking up little space when stored. Inflatable beds have an air chamber inside, and when air flows inside the chamber, heat is easily lost, resulting in low thermal insulation. When the human body uses an inflatable bed, some of the heat is dissipated directly into the air in the chamber through the surface of the bed, while the other part is dissipated through thermal radiation. Because conventional inflatable beds cannot effectively block the conduction of heat outward, the inflatable bed loses heat quickly and has poor thermal insulation when in use. Therefore, it is necessary to design an inflatable bed structure that can reduce heat conduction. Summary of the Invention

[0003] In order to solve the above problems existing in the prior art, this solution provides an inflatable bed with the function of reducing heat conduction.

[0004] The technical solution adopted in the present invention is:

[0005] An inflatable bed with a heat conduction reduction function comprises a top fabric, a bottom fabric, side fabrics, and vertical ties; the top fabric is disposed above the bottom fabric, the side fabrics are connected between the edges of the top fabric and the bottom fabric, and an inflatable cavity is formed between the top fabric, the bottom fabric, and the side fabrics; a plurality of vertical ties are distributed in the inflatable cavity in a rectangular array, with the upper ends of the vertical ties fixedly connected to the top fabric and the lower ends fixedly connected to the bottom fabric;

[0006] A horizontal reflective cloth is provided in the inflatable cavity; the edges of the horizontal reflective cloth are fixedly connected to the side cloths; a plurality of hollow holes are provided on the horizontal reflective cloth, and the vertical tie bars pass through the hollow holes;

[0007] An oblique reflective cloth is also provided in the inflation cavity. The oblique reflective cloth is located above the horizontal reflective cloth, and the cloth surface is inclined to the horizontal reflective cloth. The oblique lower edge of the oblique reflective cloth is fixedly connected to the horizontal reflective cloth, and the oblique 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 reinforcement is ring-shaped or C-shaped.

[0009] As an alternative or supplement to the above structure: when the vertical tie bars are circular, the hollow holes are rectangular; when the vertical tie bars are C-shaped, the hollow holes are long strips;

[0010] As an alternative or supplement to the above structure: the oblique reflective cloth is long and narrow, with a piece of oblique reflective cloth placed around each of the four sides of the horizontal reflective cloth; the four oblique reflective cloths are either unconnected or connected end-to-end to form a square basin-shaped structure with a larger top and a smaller bottom. As an alternative or supplement to the above structure: the top cloth, bottom cloth, side cloths, horizontal reflective cloth, and oblique reflective cloth components are all connected by welding where fixed connections are required.

[0011] As an alternative or supplement to the above structure: the horizontal reflective cloth and the oblique reflective cloth are both 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 production process includes the following steps:

[0013] A: Lay the horizontal reflective cloth with hollow holes on the welding platform, and place the oblique reflective cloth on the edge of the horizontal reflective cloth. Use heat pressing or high-frequency technology to weld the two together, welding the lower oblique edge of the oblique reflective cloth to the horizontal reflective cloth.

[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 bars through the hollow holes of the horizontal reflective fabric and weld them to the base fabric;

[0016] D: Place the first mold above the horizontal reflective cloth welded in step B, with the annular side panels inside the first mold; weld the side panels to the upper oblique edge of the oblique reflective cloth at the upper edge of the first mold; weld the side panels to the edge of the horizontal reflective cloth at the lower edge of the first mold;

[0017] E: Replace the first mold with a taller second mold, 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 cloth above the second mold, and fix the upper end of the vertical tie rod to the top cloth; at the upper edge of the second mold, weld the upper edge of the side cloth to the upper edge of the top cloth; at the lower edge of the second mold, weld the lower edge of the side cloth to the edge of the bottom cloth.

[0018] As an alternative or supplement to the above structure: the height of the first mold is 0.3 to 0.5 times the height of the side cloth; the height of the second mold is 0.7 to 0.9 times the height of the side cloth.

[0019] The beneficial effects of the present invention are:

[0020] 1. In this solution, the oblique reflective cloth and the horizontal reflective cloth can separate the air chamber in the inflatable bed into two layers, which can slow down the air flow in the air chamber, thereby alleviating the heat loss caused by the air flow and reducing the heat conduction efficiency.

[0021] 2. In addition, the oblique reflective cloth and the horizontal reflective cloth are made of materials that can reflect thermal radiation, which can reflect the heat generated by the human body in the form of thermal radiation. Moreover, since the horizontal reflective cloth and the four oblique reflective cloths cooperate to form a basin-shaped structure, the thermal radiation can be concentrated in the middle of the mattress after reflection, further reducing heat conduction and improving thermal insulation performance.

[0034] 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.

[0035] Example 1

[0036] like Figures 1 to 5 as well as Figure 10 As shown, this embodiment designs an inflatable bed with the function of reducing heat conduction, including a top cloth 1, a bottom cloth 2, a side cloth 4, vertical reinforcements 6, an oblique reflective cloth 3, a horizontal reflective cloth 5 and other components.

[0037] The top fabric 1, side fabrics 4, and bottom fabric 2 are all rectangular, breathable fabrics, typically made of TPU-coated fabric. The top fabric 1 is positioned above the bottom fabric 2, with the side fabrics 4 connected between the edges of the top fabric 1 and the bottom fabric 2. The upper edges of the side fabrics 4 are welded to the edges of the top fabric 1, and the lower edges of the side fabrics 4 are welded to the edges 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 installed on the side fabrics 4. When air is injected into the cavity through the nozzle, the airbed expands for ease of use.

[0038] Vertical tie bars 6 are positioned within the inflatable chamber. These tie bars can be circular (as shown) or C-shaped (not shown). Several tie bars 6 are arranged in a rectangular array within the inflatable chamber. The upper end of each tie bar 6 is fixedly connected to the top fabric 1, and the lower end of each tie bar 6 is fixedly connected to the bottom fabric 2. The tie bars 6 pull the top fabric 1 and bottom fabric 2 closer together, thereby achieving the desired shape of the inflatable mattress and controlling its height.

[0039] A horizontal reflective fabric 5 is disposed within the plenum chamber; its edges are fixedly connected to the side fabric 4. The horizontal reflective fabric 5 not only divides the plenum chamber into two layers, slowing air flow within the chamber and thereby alleviating heat loss and reduced heat conduction efficiency, but can also be made of a heat-reflecting material such as a non-woven composite aluminum insulation fabric or a non-woven composite cotton insulation fabric. This material can reflect heat generated by the human body in the form of thermal radiation, further reducing heat conduction and improving thermal insulation performance.

[0040] A plurality of hollow holes are provided on the horizontal reflective cloth 5 so that the vertical ties 6 can pass through the hollow holes. When the vertical ties 6 are circular, the hollow holes are rectangular, as shown in the figure. When the vertical ties 6 are C-shaped, the hollow holes are long strips, which are not shown in the figure.

[0041] The inflatable chamber is also equipped with an oblique reflective fabric 3, positioned above the horizontal reflective fabric 5. The oblique reflective fabric 3 is angled relative to the horizontal reflective fabric 5. The oblique lower edge of the oblique reflective fabric 3 is fixedly connected to the horizontal reflective fabric 5, while the oblique upper edge of the oblique reflective fabric 3 is fixedly connected to the side fabric 4. The oblique reflective fabric 3 is made of either a non-woven composite aluminum insulation fabric or a non-woven composite cotton insulation fabric to reflect thermal radiation. The horizontal reflective fabric 5 and the four oblique reflective fabrics 3 form a basin-like structure, concentrating the reflected thermal radiation toward the center of the mattress, reducing heat conduction and improving thermal insulation performance.

[0042] The oblique reflection cloth 3 is in the shape of a long strip, and one oblique reflection cloth 3 is provided on each of the four sides of the horizontal reflection cloth 5; the four oblique reflection cloths 3 are not connected to each other, as shown in the figure ( Figure 3 、 4 Alternatively, four oblique reflective cloths 3 are connected end to end to form a square basin-shaped structure with a larger top and a smaller bottom (as shown in FIG. Figure 9 When the oblique reflecting cloth 3 is formed into a square basin shape, the four corners of the oblique reflecting cloth 3 have arc-shaped chamfers, and at the same time, the basin opening end of the oblique reflecting cloth 3 is larger than the basin bottom end.

[0043] The top cloth 1, bottom cloth 2, side cloth 4, horizontal reflective cloth 5 and oblique reflective cloth 3 and other components that need to be fixedly connected can all 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 shaping the side wall, reducing the outward bulging degree of the side wall, improving the stability of the inflatable bed, and reducing the shaking of the inflatable bed during use.

[0045] Example 2

[0046] like Figures 1 to 8 As shown, when the inflatable bed in Example 1 is produced, the production process includes the following steps:

[0047] A: Lay the horizontal reflective cloth 5 with hollow holes on the welding platform, and place the oblique reflective cloth 3 on the edge of the horizontal reflective cloth 5. Use heat pressing or high-frequency welding to weld the oblique lower edge 31 of the oblique reflective cloth 3 to the horizontal reflective cloth 5.

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

[0049] C: Pass the lower ends of several vertical ribs 6 through the hollow holes of the horizontal reflective fabric 5 and weld them to the base fabric 2;

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

[0051] E: Replace the first mold 7 with the second mold 9 with a higher height, so that the upper edge of the side wall is placed at the upper edge of the second mold 9 and the lower edge is placed at the lower edge of the second mold, as shown in FIG. Figure 8 As shown; the top cloth 1 is placed above the second mold 9, and the upper ends of the vertical ribs 6 are fixedly connected (welded) to the top cloth 1; at the upper edge of the second mold 9, the upper edges of the side cloth 4 are welded to the upper edges of the top cloth 1; at the lower edge of the second mold 9, the lower edges of the side cloth 4 are welded to the edges of the bottom cloth 2;

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

[0053] The first mold 7 can be made of Figure 6 In the structure shown, the height of the first mold 7 is 0.3 to 0.5 times the height of the side cloth 4; the second mold 9 adopts 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 cloth 4.

[0054] 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.
