The present disclosure relates to the technical field of inflatable mattresses, in particular to a dual-wall inflatable mattress.
An inflatable mattress refers to a mattress with strong flexibility and elasticity, which expands after inflation. It occupies a small area after deflation and folding, and is very easy to carry, so it can be used for outdoor play, family guest bed and other use scenarios. Although the inflatable mattress is convenient to use, because it is relying on the internal gas to support the volume of the mattress, in the event of sharp objects scratching the mattress, it is easy to leak air.
In order to reduce the impact of air leakage somewhere on the overall supporting force of the mattress, the current inflatable mattress, such as an independent air column inflatable mattress provided in 201610893716.8, provides a honeycomb column mattress. After the independent air column is inflated, under the action of the inflation one-way valve and the deflation one-way valve, the gas in the air column can be guaranteed not to flow backwards, so that each air column can maintain uniform air pressure. The applicant believes that this patent only provides a method for preventing air leakage of honeycomb column mattress, while the inflatable mattress is currently divided into honeycomb type and drawstring type, and the method of this patent cannot solve the problem of preventing air leakage of an integral air bag of the drawstring type mattress. When sharp objects are stuck to the side of the mattress, the air bag used to support the volume of the mattress will leak. Therefore, it is necessary to provide a drawstring mattress which can reduce the probability of air leakage.
In order to overcome the shortcomings of the prior art, the present disclosure aims to provide a dual-wall inflatable mattress to solve the problems mentioned in the background art.
In order to achieve the above purpose, the present disclosure adopts the following technical solution:
The outer circumferential sheet and the inner peripheral sheet serve as inner and outer walls, and air chambers are arranged inside the inner peripheral sheet and between the outer circumferential sheet and the inner peripheral sheet. When the peripheral sheet is scratched by a sharp object during use, the second air chamber leaks air, but the first air chamber normally supports the mattress, and the mattress does not sink suddenly, thereby effectively protecting the safety of a user.
Further, the first air chamber and the second air chamber are provided with air nozzles for inflating and deflating air. Each air chamber is inflated and deflated independently, and the air chambers are not communicated with each other, so that the air leakage phenomenon of a certain air chamber can be determined in time through the inflating state of the two air chambers.
Further, the side circumferential sheet is further provided with a plurality of connecting parts configured for a fixed connection between the outer peripheral sheet and the inner peripheral sheet.
By partially connecting the outer and inner peripheral sheets, the outer and inner peripheral sheets are made to expand within a reasonable range when the first and second air chambers are inflated, preventing excessive outward expansion of the first and second air chambers. At the same time, the double wall is more supportive around the mattress after inflation and can carry higher weight.
Furthermore, the connecting part is formed by hot-melt welding of the outer peripheral sheet and the inner peripheral sheet.
Furthermore, the connecting part is annular.
Further, a plurality of inner drawstrings are arranged in the first air chamber, and the inner drawstrings are hot-melt welded between the top sheet and the bottom sheet. The inner drawstring is provided so that the position of the top sheet and the bottom sheet remain within a reasonable range when the first air chamber is inflated, thereby preventing excessive outward expansion of the first air chamber.
Further, the inner peripheral sheet defines the annular second air chamber in the inner volume. The annular second air chamber prevents the expansion of the first air chamber, and when the first air chamber expands to a certain degree, the second air chamber limits the continued outward expansion of the first air chamber.
Furthermore, a circumference of the inner peripheral sheet is smaller than a circumference of the outer peripheral sheet. The outer perimeter sheet is pulled inward by the inner peripheral sheet and the connecting part after inflation, so that the outer perimeter sheet cannot be excessively deformed due to inflation, causing the side walls to bulge out into an oval shape.
Furthermore, either of the top sheet, the bottom sheet, the outer peripheral sheet and the inner peripheral sheet includes a flexible air-impermeable material.
Compared with the prior art, the present disclosure has the advantages that:
In order to more clearly illustrate the technical solution of the embodiments of the present disclosure, the following will briefly introduce the drawings that are desired to be used in the description of the embodiments. Obviously, the drawings in the following description are merely some embodiments of the present invention, and other drawings may also be obtained according to these drawings without exerting inventive effort by those ordinarily skilled in the art.

In order to explain the present disclosure more clearly, the present disclosure is further described in detail in combination with the embodiment and with reference to the drawings. It will be understood by those skilled in the art that the following detailed description is illustrative and not limiting and is not intended to limit the scope of protection of the present disclosure.
In the description of the present disclosure, it should be understood that, orientation or positional relationships indicated by terms such as “inner”, “outer”, “up”, “down” are based on the orientation or positional relationships shown in the drawings, for ease of description of the present disclosure and simplification of the description only, these terms do not indicate or imply that the apparatus or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be construed as limitations to the present disclosure. In addition, unless otherwise expressly specified and limited, the terms “mounted”, “connect” etc. should be understood in a broad sense, for example, they can be fixed connections, detachable connections or integral connections; mechanical connections or electrical connections; and direct connections or indirect connections through an intermediate medium, or can be the internal connectivity of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure will be understood according to the specific circumstances.
As shown in
The outer peripheral sheet 5 and the inner peripheral sheet 6 serve as inner and outer walls, and an air chamber is provided inside the inner peripheral sheet 6 and between the outer peripheral sheet 5 and the inner peripheral sheet 6. The first air chamber 7 is enclosed by the top sheet 1, the bottom sheet 2 and the inner peripheral sheet 6, and the second air chamber 8 is an annular air chamber enclosed by the top sheet 1, the bottom sheet 2, the outer peripheral sheet 5 and the inner peripheral sheet 6. When the peripheral sheet is scratched by sharp objects in use, the second air chamber 8 leaks air, but the first air chamber 7 can normally support the mattress, so that the mattress will not suddenly sag and the user can be protected.
In order to improve the supporting force of the side wall of the mattress, a plurality of connecting parts 3 are also arranged on the side circumferential sheet, and the connecting parts 3 are formed by hot-melt welding of the outer peripheral sheet and the inner peripheral sheet without blocking the air path in the second air chamber 8. In this embodiment, the connecting parts are annular and are arranged on the side circumferential sheet at equal intervals, which is used for the fixed connection between the outer peripheral sheet 5 and the inner peripheral sheet 6. At the same time, the double wall is more supportive around the mattress after inflation and can carry higher weight. By partially connecting the outer and inner peripheral sheets, the outer peripheral sheet 5 and the inner peripheral sheet 6 are made to expand within a reasonable range when the first air chamber 7 and the second air chamber 8 are inflated, preventing excessive outward expansion of the first air chamber 7 and the second air chamber 8.
When a circumference of the inner peripheral sheet 6 is smaller than a circumference of the outer peripheral sheet 5. The outer perimeter sheet 5 is pulled inward by the inner peripheral sheet 6 after inflation due to the presence of the connecting part 3, so that the outer perimeter sheet 5 is not excessively deformed by inflation, causing the side walls to bulge out into an oval shape.
Both the first air chamber 7 and the second air chamber 8 are provided with air nozzles for inflating and deflating air. The first air chamber 7 is provided with an air nozzle A9, and the second air chamber 8 is provided with an air nozzle B10, so that each air chamber is independently inflated and deflated. The air nozzle A9 is arranged on the connecting part 3 and directly communicates with the first air chamber 7 through the connecting part 3. The air nozzle B10 is arranged on the outer peripheral sheet 5 and directly communicates with the second air chamber 8 through the outer peripheral sheet 5. The air chambers are not communicated with each other, so that the air leakage phenomenon of a certain air chamber can be determined in time through the inflating state of the two air chambers. For example, the first air chamber 7 may be filled first, and if the volume of the second air chamber 8 becomes larger during the filling process, it means that the inner peripheral sheet 6 leaks air.
In addition, a plurality of inner drawstrings 4 are arranged in the first air chamber 7, and the inner drawstrings 4 are hot-melt welded between the top sheet 1 and the bottom sheet 2. The inner drawstring 4 is provided so that the position of the top sheet 1 and the bottom sheet 2 remain within a reasonable range when the first air chamber 7 is inflated, thereby preventing excessive outward expansion of the first air chamber 7.
Apparently, the above-mentioned embodiment of the present disclosure is only an example for more clearly explaining the present disclosure, instead of limiting the implementation mode of the present disclosure, for those of ordinary skill in the art, other changes or modifications in different forms can be made on the basis of the above description, and all implementation methods cannot be exhaustively enumerated here, and all obvious changes or modifications derived from the technical solution of the present disclosure are still within the protection scope of the present disclosure.
