Description

Technical Field

[0001] The present invention relates to the technical field of inflatable products, and in particular to an inflation structure, an inflatable product, and a manufacturing method of an inflatable product. Background Art

[0002] In order to improve the thermal insulation coefficient of the air cushion (Thermal insulance, with the unit of (m²K) / W in the International System of Units) in the inflatable products on the market, hollow fiber cotton is usually added inside the air cushion to reduce the heat convection inside the air cushion.

[0003] Hollow fiber cotton is a high-warmth floc cotton product, with the raw material being polyester filament. It takes thick hollow fibers as the main trunk, and synthetically winds fine hollow fibers around the thick trunk to produce a dendritic structure like down. In the unfolded state, it can form a large number of air chambers with a volume smaller than that of water molecules. These air chambers can retain the heat emitted by the body. However, when hollow fiber cotton is used in the manufacturing and use process of the inflatable cushion, it is in a compressed or incompletely unfolded state, so that the excellent heat insulation performance of the material cannot be fully exerted.

[0004] Moreover, when a reflective layer is provided in the inflatable product, when it is pressed by pressure during use, the reflective layer is slightly distorted and is likely to emit a relatively large noise, affecting the user experience of those with light sleep. Summary of the Invention

[0005] The purpose of the present invention is to provide an inflation structure, an inflatable product, and a manufacturing method of an inflatable product to solve the technical problems that the heat insulation performance of the inflatable product cannot be fully exerted, and the reflective layer provided in the inflatable product is prone to generate noise and affect the user's sleep.

[0006] In a first aspect, the present invention provides an inflation structure, including a first layer and a second layer; a plurality of baffles are provided between the first layer and the second layer, and adjacent two of the baffles form a first tubular cavity between the first layer and the second layer, and a composite material is provided in the first tubular cavity;

[0007] The composite material includes a plurality of fillers stacked in sequence 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.

[0008] In an optional embodiment, the materials of the first layer, the second layer, and the baffles are one of a textile with a PVC coating, a textile with a TPU coating, a PVC film, and a TPU film.

[0009] In an optional embodiment, the filler is hollow fiber cotton.

[0012] In an alternative embodiment, a composite material is disposed in the second tubular cavity.

[0013] A composite material is disposed between the first layer and the second layer of the inflatable structure of the present invention. The composite material is respectively stretched by the first layer and the second layer. The stretched filler adheres to the upper and lower surfaces of the reflective layer like two spring structures. When external vibrations are conducted to the reflective layer, they will all be attenuated; therefore, the reflective layer can stably remain in the central position between the first layer and the second layer all the time and will not make a noisy sound due to distortion;

[0014] Similarly, due to the connection of the composite material with the first layer and the second layer respectively, the composite material is in a stretched state, increasing the volume percentage occupied by the filler in the first tubular cavity and bringing the excellent performance of the filler into play.

[0031] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] Embodiment

[0033] Refer to Figures 1 - 2; The present invention provides an inflatable structure, which includes a first layer 100 and a second layer 200; a plurality of baffles 600 are arranged between the first layer 100 and 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, and a composite material 300 is arranged in the first tubular cavity 400;

[0034] The composite material 300 includes a plurality of fillers 301 stacked in sequence from top to bottom, a reflective layer 302 is arranged 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.

[0035] In some embodiments, a plurality of baffles 600 are arranged 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. 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 can also be the width direction of the inflatable structure.

[0036] 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 arranged at each of the upper and lower ends of the reflective layer 302. The composite material 300 is connected to the first layer 100 and the second layer 200 through the fillers 301 respectively; when the inflatable structure is in an inflated state, the distance between the first layer 100 and the second layer 200 is larger, and the first layer 100 and the second layer 200 are respectively stretched at both ends of the composite material 300, so that the fillers 301 are in a stretched state. The stretched fillers 301 are attached to the upper and lower surfaces of the reflective layer 302 like two spring structures. When external vibration is transmitted to the reflective layer 302, it will be attenuated; therefore, the reflection can always be stably in the central position between the first layer 100 and the second layer 200 and will not make a noisy sound 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 in the central position and is generally in a horizontal state.

[0037] Similarly, due to the connection between the fillers 301 and the first layer 100 and the second layer 200, the fillers 301 are in a stretched state, which increases the volume percentage occupied by the fillers 301 in the first tubular cavity 400 and gives full play to the excellent performance of the fillers 301.

[0038] Among them, the filler 301 can be connected to the reflective layer 302 through a vinyl acetate-ethylene copolymer emulsion.

[0039] Reference Figure 1 , the first layer 100 is above the second layer 200, and the reflective layer 302 is horizontal.

[0040] In an alternative embodiment, the materials of the first layer 100, the second layer 200, and the baffle 600 are one of a fabric with a PVC coating, a fabric with a TPU coating, a PVC film, and a TPU film.

[0041] In an alternative embodiment, the filling 301 is hollow fiber cotton.

[0042] In an alternative embodiment, the reflective layer 302 is an aluminized PET film or aluminum foil; the filling 301 is adhered to the reflective layer 302.

[0043] The filling 301 is generally hollow fiber cotton; the first layer 100 and the second layer 200 are made of a fabric with a PVC coating; the reflective layer 302 is an aluminized PET film, which has good performance in reducing human body heat radiation and a very low gram weight per square meter; the baffle 600 is made of a fabric with a 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 generally use the same material, and the connection between the baffle 600 and the first layer 100 and the second layer 200 can also use chemical reactions.

[0044] In an alternative embodiment, the edge of the first layer 100 is connected to the edge of the second layer 200, connection cavities 800 communicating with the first tubular cavity 400 are formed at both ends in the length direction of the first tubular cavity 400, and second tubular cavities 500 are formed on both sides in the length direction of the first tubular cavity 400.

[0045] In order to enable the inflatable structure to inflate and deflate multiple first tubular cavities 400 and multiple second tubular cavities 500 simultaneously with only one air nozzle 700; connection cavities 800 are formed at both ends of the inflatable structure in the length direction of the first tubular cavity 400; at least one connection cavity 800 is provided at one end of the inflatable structure in the length direction, and the air nozzle 700 is provided on the first layer 100 or the second layer 200. The airflow entering the air nozzle 700 can enter the connection cavity 800, and then the airflow enters the first tubular cavity 400 and the second tubular cavity 500 through the connection cavity 800; for the flow rate of the airflow, generally one connection cavity 800 is provided at each end of the inflatable structure in the length direction; when the second tubular cavity 500 is not inserted into the composite material 300, that is, after the airflow enters the connection cavity 800 from the air nozzle 700, the airflow flows along the connection cavity 800, passes through the second tubular cavity 500 and flows to both ends of the first tubular cavity 400, thereby increasing the speed of inflating the inflatable structure.

[0046] A composite material 300 is provided between the first layer 100 and the second layer 200 of the inflatable structure of the present invention. The composite material 300 is respectively stretched by the first layer 100 and the second layer 200. After stretching, the 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 will all be attenuated; therefore, the reflective layer 302 can always be stably located at the central position between the first layer 100 and the second layer 200 and will not make a noisy sound due to distortion;

[0047] Similarly, due to the connection of the composite material 300 with the first layer 100 and the second layer 200 respectively, the composite material 300 is in a stretched state, increasing the volume percentage occupied by the filler 301 in the first tubular cavity 400 and giving full play to the excellent heat insulation performance of the filler 301.

[0048] Refer to Figures 3 - 4 The present invention also provides an inflatable product, including the inflatable structure described in any one of the foregoing embodiments.

[0049] In an alternative embodiment, it further includes an air nozzle 700. The air nozzle 700 is provided on the first layer 100 or the second layer 200, and the air nozzle 700 is communicated with the connection cavity 800.

[0050] The present invention also provides an inflatable product. The inflatable product adopts the above-mentioned inflatable structure, and thus has all the beneficial effects of the inflatable structure.

[0051] Refer to Figure 5 The present invention provides a method for manufacturing an inflatable product, including the following steps:

[0052] 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;

[0053] S2. Insert the composite material 300 into the first tubular cavity 400 and make the reflective layer 302 horizontal;

[0054] S3. Heat outside the first layer 100 to melt the coating on the inner wall of the first tubular cavity 400, and weld the upper end of the composite material 300 to the first layer 100; heat outside the second layer 200 to melt the coating on the inner wall of the first tubular cavity 400, and weld the lower end of the composite material 300 to the second layer 200;

[0055] S4. Weld the edge of the first layer 100 and the edge of the second layer 200 together.

[0056] In an alternative embodiment, before step S1, there is also S0: Bond the filler 301 to the reflective layer 302 to form the composite material 300.

[0057] The composite material 300 may include one reflective layer 302, two reflective layers 302 or multiple reflective layers 302. The reflective layer 302 is arranged between adjacent two fillers 301. The composite material 300 can be mass-produced during the production process.

[0058] The manufacturing method of the inflatable product first composes 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, realizing simple mass production.

[0059] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
