Description

Double-layer wall inflatable mattress

Technical Field

The utility model relates to the technical field of inflatable mattresses, in particular to a double-layer wall inflatable mattress.

Background

The inflatable mattress has stronger flexibility and elasticity, is inflated, occupies smaller area after being deflated and folded, is very easy to carry, and can be used for use scenes such as going out for carrying, making a guest bed at home, and the like. Although the inflatable mattress is convenient to use, because the inflatable mattress is supported by the air inside, the inflatable mattress is easy to leak air when the inflatable mattress is scratched by sharp objects.

In order to reduce the influence of air leakage at a certain position of the mattress on the whole supporting force of the mattress, an independent air column type air mattress provided by the prior air mattress, such as 201610893716.8, is provided, and after the independent air columns are inflated, the air in the air columns can be ensured not to flow backwards under the action of an inflation one-way valve and an deflation one-way valve, so that each air column can keep uniform air pressure. The applicant believes that this patent only provides a means of air-tightness for cellular column mattresses, and inflatable mattresses are currently classified as cellular and drawstring, which does not address air-tightness for drawstring integral airbags. When sharp objects are pricked to the sides of the mattress, the air bag used to support the mattress volume leaks. It is therefore desirable to provide a pull-down mattress that reduces the probability of air leakage.

Further, the connecting portion is annular.

Further, a plurality of inner pull straps are arranged in the first air chamber, and the inner pull straps are welded between the top sheet and the bottom sheet in a hot-melt mode. The inner pull straps are arranged so that the positions of the top sheet and the bottom sheet are kept within a reasonable range when the first air chamber is inflated, and the first air chamber is prevented from being excessively expanded outwards.

Further, the inner Zhou Pian separates the inner cavity into an annular second air chamber. The annular second air chamber can prevent the expansion of the first air chamber, and when the first air chamber expands to a certain degree, the second air chamber can limit the continuous expansion of the first air chamber.

Further, the circumference of the inner part Zhou Pian is smaller than that of the outer part Zhou Pian, and the outer peripheral piece is subjected to inward tension of the inner peripheral piece and the connecting part after inflation, so that the outer peripheral piece cannot be excessively deformed due to inflation, and the side wall bulges to be elliptical.

Still further, the top sheet, bottom sheet, outer peripheral sheet and inner Zhou Pian are all made of a flexible, air impermeable material.

Compared with the prior art, the utility model has the following beneficial effects:

the inflatable mattress adopts a double-layer wall body, and the support on the periphery of the mattress is stronger after inflation. Even if the outer peripheral piece breaks, the inner peripheral piece can keep the gas of the inner gas chamber from leaking, so that the safety of the product is improved. Meanwhile, the arrangement of the double-layer air chamber can also effectively reduce excessive deformation of the mattress during inflation, the inner pull belt can prevent the top sheet and the bottom sheet from being excessively expanded, and the second air chamber can prevent the inner Zhou Pian of the first air chamber from being excessively expanded.
