[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202210392078.7 filed with the Chinese Patent Office on April 14, 2022, entitled “Inflatable Structure, Inflatable Product and Method for Making Inflatable Product,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of inflatable products, and in particular to an inflatable structure, an inflatable product, and a method for manufacturing an inflatable product. Background Art

[0004] In order to improve the thermal insulation coefficient of the air cushion (Thermal insulation, the unit under the international standard system is (m 2 K) / W), hollow fiber cotton is usually added inside the air cushion to reduce heat convection inside the air cushion.

[0005] Hollow fiber cotton is a highly warm cotton product. Its raw material is polyester yarn, with thick hollow fiber as the main trunk, and fine hollow fibers are synthetically wrapped around the thick trunk to produce a down-like tree structure. When unfolded, it can form a large number of air chambers smaller than water molecules. These air chambers can retain the heat emitted by the body. However, when hollow fiber cotton is used in the manufacture and use of inflatable cushions, it is in a compressed or unable to fully unfold state, which makes it impossible to fully utilize the material's high-quality thermal insulation properties.

[0006] In addition, a reflective layer is set inside the inflatable product. When in use, the pressure is squeezed onto the reflective layer, and the reflective layer is slightly distorted, which can easily make a loud noise and affect the user experience of light sleepers.

[0007] Summary of the Invention

[0008] The purpose of this application is to provide an inflatable structure, an inflatable product and a method for manufacturing an inflatable product, so as to solve the technical problems that the thermal insulation performance of the inflatable product cannot be fully exerted, and the reflective layer provided in the inflatable product is prone to generate noise, affecting the user's sleep.

[0009] In a first aspect, the present application provides an inflatable structure comprising a first layer and a second layer; a plurality of baffles are disposed between the first layer and the second layer, wherein two adjacent baffles form a first tubular cavity between the first layer and the second layer, and a composite material is disposed in the first tubular cavity;

[0010] The composite material includes a plurality of fillers stacked sequentially from top to bottom, a reflective layer is provided between two adjacent fillers, the upper end of the composite material is connected to the first layer, and the lower end of the composite material is connected to the second layer.

[0011] In an optional embodiment, the first layer, the second layer, and the baffle are made of one of a textile with a PVC coating, a textile with a TPU coating, a PVC film, and a TPU film.

[0012] In an optional embodiment, the filler is hollow fiber cotton.

[0013] In an optional embodiment, the reflective layer is an aluminized PET film or aluminum foil; and the filler is adhered to the reflective layer.

[0015] In an optional embodiment, a composite material is disposed in the second tubular cavity.

[0016] The inflatable structure of the present invention comprises a composite material disposed between the first and second layers. The composite material is stretched by the first and second layers, respectively. The stretched filler adheres to the upper and lower surfaces of the reflective layer like two spring structures. When external vibrations are transmitted to the reflective layer, they are absorbed. As a result, the reflective layer remains stably positioned in the center between the first and second layers, without generating noise due to distortion.

[0017] Likewise, due to the connection between the composite material and the first layer and the second layer, the composite material is in a stretched state, which increases the volume percentage of the filler in the first tubular cavity and enables the excellent performance of the filler to be brought into play.

[0034] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] Example

[0036] 1-2 ; the present application provides an inflatable structure, comprising a first layer 100 and a second layer 200 ; a plurality of baffles 600 are disposed between the first layer 100 and the second layer 200 , wherein two adjacent baffles 600 form a first tubular cavity 400 between the first layer 100 and the second layer 200 , and a composite material 300 is disposed in the first tubular cavity 400 ;

[0037] The composite material 300 includes a plurality of fillers 301 stacked sequentially from top to bottom, a reflective layer 302 is provided between two adjacent fillers 301 , the upper end of the composite material 300 is connected to the first layer 100 , and the lower end of the composite material 300 is connected to the second layer 200 .

[0038] In some embodiments, a plurality of baffles 600 are provided between the first layer 100 and the second layer 200; one end of the plurality of baffles 600 is connected to the first layer 100 and the other end is connected to the second layer 200, and two adjacent baffles 600 form a first tubular cavity 400 between the first layer 100 and the second layer 200. Generally, the length direction of the first tubular cavity 400 is the length direction of the inflatable structure, and the length direction of the first tubular cavity 400 may also be the width direction of the inflatable structure.

[0039] The composite material 300 can be inserted into the first tubular cavity 400. The composite material 300 generally includes at least two fillers 301 and a reflective layer 302. A filler 301 is provided at the upper and lower ends of the reflective layer 302, respectively. The composite material 300 is connected to the first layer 100 and the second layer 200 through the fillers 301. When the inflatable structure is inflated, the distance between the first layer 100 and the second layer 200 is large. The first layer 100 and the second layer 200 are stretched at both ends of the composite material 300, causing the fillers 301 to be stretched. The stretched fillers 301 adhere to the upper and lower surfaces of the reflective layer 302 like two spring structures. When external vibrations are transmitted to the reflective layer 302, they are attenuated. Therefore, the reflection can be stably and continuously located at the center between the first layer 100 and the second layer 200, without generating noise due to distortion. The fillers 301 on both sides of the reflective layer 302 of the composite material 300 are generally symmetrically arranged, so that the reflective layer 302 is located in the center and is generally horizontal.

[0040] Likewise, due to the connection between the filler 301 and the first layer 100 and the second layer 200 , the filler 301 is in a stretched state, which increases the volume percentage of the filler 301 in the first tubular cavity 400 and enables the excellent performance of the filler 301 to be brought into play.

[0041] The filler 301 may be connected to the reflective layer 302 via vinyl acetate-ethylene copolymer emulsion.

[0042] 1 , the first layer 100 is located above the second layer 200 , and the reflective layer 302 is horizontal.

[0043] In an optional embodiment, the first layer 100, the second layer 200, and the baffle 600 are made of one of a textile with a PVC coating, a textile with a TPU coating, a PVC film, and a TPU film.

[0044] In an optional embodiment, the filler 301 is hollow fiber cotton.

[0045] In an optional embodiment, the reflective layer 302 is an aluminized PET film or aluminum foil; and the filler 301 is adhered to the reflective layer 302 .

[0046] The filler 301 is generally hollow fiber cotton; the first layer 100 and the second layer 200 are made of textile with PVC coating; the reflective layer 302 is made of aluminized PET film, which has a good performance in reducing human body heat radiation and has a very low gram weight per square meter; the baffle 600 is made of textile with PVC coating; when the baffle 600 needs to be connected to the first layer 100 and the second layer 200, the PVC coating on the baffle 600 is melted by heating, thereby realizing the welding of the baffle 600 to the first layer 100 and the second layer 200. The first layer 100, the second layer 200 and the baffle 600 are generally made of the same material, and the connection between the baffle 600 and the first layer 100 and the second layer 200 can also be achieved by chemical reaction.

[0047] In an optional embodiment, the edge of the first layer 100 is connected to the edge of the second layer 200, and a connecting cavity 800 connected to the first tubular cavity 400 is formed at both ends of the first tubular cavity 400 in the longitudinal direction, and a second tubular cavity 500 is formed on both sides of the first tubular cavity 400 in the longitudinal direction.

[0048] In order to enable the inflatable structure to simultaneously inflate and deflate multiple first tubular cavities 400 and multiple second tubular cavities 500, a single air nozzle 700 is provided. Connecting cavities 800 are formed at both ends of the inflatable structure along the length of the first tubular cavity 400. The connecting cavity 800 is provided at at least one end of the inflatable structure along the length. The air nozzle 700 is provided on the first layer 100 or the second layer 200. The airflow entering through the air nozzle 700 can enter the connecting cavity 800, and then the airflow enters the first tubular cavity 400 and the second tubular cavity 500 through the connecting cavity 800. To increase the flow rate of the airflow, a connecting cavity 800 is generally provided at each end of the inflatable structure along the length. When the second tubular cavity 500 is not inserted into the composite material 300, that is, when the airflow enters the connecting cavity 800 from the air nozzle 700, the airflow flows along the connecting cavity 800, through the second tubular cavity 500, and flows to both ends of the first tubular cavity 400, thereby increasing the speed at which the airflow inflates the inflatable structure.

[0049] The composite material 300 is disposed between the first layer 100 and the second layer 200 of the inflatable structure of the present application. The composite material 300 is stretched by the first layer 100 and the second layer 200, respectively. The stretched filler 301 adheres to the upper and lower surfaces of the reflective layer 302 like two spring structures. When external vibrations are transmitted to the reflective layer 302, they are absorbed. As a result, the reflective layer 302 can be stably positioned in the center between the first layer 100 and the second layer 200, without generating noise due to distortion.

[0050] Similarly, due to the connection between the composite material 300 and the first layer 100 and the second layer 200 respectively, the composite material 300 is in a stretched state, which increases the volume percentage of the filler 301 in the first tubular cavity 400 and enables the excellent thermal insulation performance of the filler 301 to be brought into play.

[0051] 3-4 , the present application further provides an inflatable product, comprising the inflatable structure described in any one of the aforementioned embodiments.

[0052] In an optional embodiment, an air nozzle 700 is further included. The air nozzle 700 is disposed on the first layer 100 or the second layer 200 , and the air nozzle 700 is communicated with the connecting cavity 800 .

[0053] The present application also provides an inflatable product, which adopts the above-mentioned inflatable structure and thus has all the beneficial effects of the inflatable structure.

[0054] 5 , the present application provides a method for manufacturing an inflatable product, comprising the following steps:

[0055] S1. Weld the upper and lower ends of multiple baffles 600 to the first layer 100 and the second layer 200 respectively to form multiple first tubular cavities 400;

[0056] S2. Insert the composite material 300 into the first tubular cavity 400, and make the reflective layer 302 horizontal;

[0057] S3. Heat the outer surface of the first layer 100 to melt the coating on the inner wall of the first tubular cavity 400, thereby welding the upper end of the composite material 300 to the first layer 100; heat the outer surface of the second layer 200 to melt the coating on the inner wall of the first tubular cavity 400, thereby welding the lower end of the composite material 300 to the second layer 200;

[0058] S4. Weld the edge of the first layer 100 and the edge of the second layer 200 together.

[0059] In an optional embodiment, before step S1 , the step further includes S0 : bonding the filler 301 to the reflective layer 302 to form the composite material 300 .

[0060] The composite material 300 may include one reflective layer 302 , two reflective layers 302 or multiple reflective layers 302 , and the reflective layer 302 is disposed between two adjacent fillers 301 . The composite material 300 may be mass-produced during the production process.

[0061] The manufacturing method of the inflatable product firstly composites the filler 301 and the reflective layer 302, and then combines the composite material 300 with the first layer 100 and the second layer 200, thereby realizing simple mass production.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
