Abstract

This utility model belongs to the field of inflatable mattress technology, specifically relating to an inflatable mattress with a perforated reflective film. It includes an inflatable mattress body with an inflation cavity inside. Within the inflation cavity, there are reinforcing ribs and a perforated reflective film. The edges of the perforated reflective film are connected to the inner wall of the inflation cavity, and several perforations are provided on the perforated reflective film. Several reinforcing ribs are independent of each other; the upper end of each reinforcing rib is connected to the inner top wall of the inflation cavity, and the lower end of each reinforcing rib passes through the corresponding perforation and connects to the inner bottom wall of the inflation cavity.

Description

Technical Field

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

[0002] In existing inflatable mattresses, a reflective film is often installed inside to reflect heat radiation, thereby improving thermal insulation performance. For example, patent CN116616580A discloses an inflatable mattress with a reflective heat insulation film, including an upper air barrier film, a lower air barrier film, a reflective heat insulation film, an upper baffle, and a lower baffle; an air bladder cavity is formed between the upper and lower air barrier films; the reflective heat insulation film is disposed within the air bladder cavity; multiple upper baffles are disposed between the reflective heat insulation film and the upper air barrier film; multiple lower baffles are disposed between the reflective heat insulation film and the lower air barrier film; and multiple intermediate supporting baffles are disposed between adjacent layers of reflective heat insulation film.

[0003] However, in this structure, the upper and lower baffles require welding at the reflective film, which is difficult to perform. When using an array of tie rods, the welding workload is large, resulting in high labor costs. Therefore, it is necessary to design an inflatable cushion structure that allows the tie rods to pass through the reflective film, thereby reducing the welding workload. Utility Model Content

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

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

[0006] An inflatable mat with a perforated reflective film includes an inflatable mat body with an inflation cavity inside; a tie rod and a perforated reflective film are provided inside the inflation cavity; the edges of the perforated reflective film are connected to the inner wall of the inflation cavity, and a plurality of perforations are provided on the perforated reflective film; the tie rods are independent of each other, the upper end of the tie rod is connected to the inner top wall of the inflation cavity, and the lower end of the tie rod passes through the corresponding perforation and is connected to the inner bottom wall of the inflation cavity.

[0007] As an alternative or supplement to the above structure: the number of the perforated reflective films is one or more; when there are multiple perforated reflective films, the perforated reflective films are arranged at intervals from top to bottom.

[0008] As an alternative or supplement to the above structure, there are two perforated reflective films.

[0009] As an alternative or supplement to the above structure: the main body of the inflatable pad includes a top fabric, side wall fabrics and a bottom fabric; the top fabric is located above the bottom fabric, and the side wall fabrics are connected between the edges of the top fabric and the bottom fabric, and the three together form the inflatable cavity.

[0010] As an alternative or supplement to the above structure: the upper end of the tie rod is fused to the top fabric, the upper end of the tie rod is fused to the bottom fabric, and the edges around the perforated reflective film are fused to the side wall fabric.

[0011] As an alternative or supplement to the above structure: the tie rod is O-shaped or I-shaped, and the hollow hole is rectangular or elongated, with each tie rod passing through one hollow hole.

[0012] As an alternative or supplement to the above structure: several tie rods are distributed in a rectangular array.

[0013] As an alternative or supplement to the above structure: the vertical sides of each tie rod are oriented in the same direction or perpendicular to each other.

[0014] The beneficial effects of this utility model are as follows: In this solution, the perforated reflective film is placed in the middle of the inflation cavity, which can reflect the heat radiated by the human body and at the same time reduce the air flow in the inflation cavity, thereby improving the heat preservation performance of the inflation pad; at the same time, since there is no need to weld between the tie rods and between the tie rods and the perforated reflective film, the amount of welding work is reduced, the number of welding points is reduced, and the production efficiency is improved.

[0022] 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.

[0023] like Figures 1 to 5 As shown, this embodiment designs an inflatable cushion with a perforated reflective film 3, including an inflatable cushion body.

[0024] The inflatable pad body includes a top fabric 1, side wall fabrics 2, and a bottom fabric 6. The top fabric 1 is located above the bottom fabric 6, and the side wall fabrics 2 connect the edges of the top fabric 1 and the bottom fabric 6. The top fabric 1, side wall fabrics 2, and bottom fabric 6 together form an inflation cavity, which is located inside the inflatable pad body. An inflation nozzle 5 with a one-way valve is installed on the side wall fabric 2, allowing inflation and deflating of the inflation cavity. The top fabric 1, side wall fabrics 2, and bottom fabric 6 can be made of fabric with a coating (TPU coating or PVC coating) on ​​one side. The coating is located on the inside of the fabric, ensuring that the coating is on the inner wall of the inflation cavity after the inflatable pad body is manufactured.

[0025] A perforated reflective film 3 is installed inside the inflation chamber. Several perforations are provided on the perforated reflective film 3. The number of perforated reflective films 3 is one or more, generally two. Figure 2 As shown; when there are multiple perforated reflective films 3, the perforated reflective films 3 are arranged at intervals from top to bottom. The edges of each perforated reflective film 3 are connected to the inner wall of the inflation chamber, that is: the edges of the perforated reflective film 3 are fused to the side wall fabric 2.

[0026] A series of tie rods 4 are installed inside the inflation chamber. Each tie rod 4 is independent of the others. The upper end of each tie rod 4 is connected to the inner top wall of the inflation chamber, and the lower end of each tie rod 4 passes through a corresponding perforated hole and is connected to the inner bottom wall of the inflation chamber. The upper ends of the tie rods 4 are fused to the top fabric 1 and the bottom fabric 6. The edges of the perforated reflective film 3 are fused to the side wall fabric 2. The tie rods 4 can be made of a thin film (TPU film or PVC film), or they can be made of a fabric or non-woven fabric with a coating (TPU coating or PVC coating) on ​​one side. The coating on the tie rod 4 faces the coating on the top fabric 1, the side wall fabric 2, and the bottom fabric 6, thus facilitating heat fusion welding.

[0027] The tension bar 4 can be O-shaped, such as... Figure 1-5 As shown, the tie rod 4 can also be I-shaped (not shown in the figure). When the tie rod 4 is O-shaped, the hollow hole is rectangular. At this time, the tread marks on the top fabric 1 and the bottom fabric 6 are rectangular. When the tie rod 4 is I-shaped, the hollow hole is elongated. Each tie rod 4 passes through a corresponding hollow hole. At this time, the tread marks on the top fabric 1 and the bottom fabric 6 are elongated.

[0028] Several reinforcing ribs 4 are arranged in a rectangular array, and the perforated holes on the perforated reflective film 3 are also arranged in a rectangular array, with each perforated hole corresponding to the previous one.

[0029] The vertical sides of each tie rod 4 face the same direction (e.g., Figure 2 As shown in the figure, the vertical sides of each tie rod 4 can also be perpendicular to each other (not shown in the figure).

[0030] 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.
