Abstract

The present utility model proposes a three-layer inflatable cushion, which comprises three layers of air cushions and is composed of at least five layers of fabrics, which are in sequence: a top layer, a first inner layer, a spacer layer, a second inner layer and a bottom layer. Through holes are evenly distributed on the spacer layer. Middle parts of the first inner layer and the second inner layer are joined at the positions of the through holes to form internal joint points. Middle parts of the top layer and the first inner layer are joined at positions not aligned with the through holes to form top joint points. Middle parts of the bottom layer and the second inner layer are joined at positions not aligned with the through holes to form bottom joint points. Peripheral parts of the top layer, the first inner layer, the spacer layer, the second inner layer and the bottom layer are press-fit and joined, and provided with air nozzles. The present utility model has three layers of air cushions which have a good heat retention performance, and is provided with an spacer layer that has through holes, which may prevent the top layer and another layer or the bottom layer and another layer from being mistakenly joined to form joint points when the top layer is joined with the first inner layer and the bottom layer is joined with the second inner layer.

Description

A three-layer inflatable cushion

technical field

The utility model relates to a three-layer inflatable cushion.

Background technique

The inflatable mattress is an inflated air mattress, which can be used indoors and outdoors. Outdoors, it can be used with a tent. A single air mattress or inflatable mattress can be folded and packed in a travel bag after the gas is exhausted. It is easy to carry. Due to its small size and light weight, the small air cushion is more convenient to carry around, and can be used to sit down and rest at any time. The air mattress is inflated and placed in the tent when resting at night. As a mattress, it is moisture-proof and comfortable. The reconnaissance air bed matched with the military tent is the best application example.

technical problem

At present, the inflatable cushions on the market are simple in structure. Generally, the internal air chamber is tubular and single-layer. Although the people and the ground are isolated, in the inflatable cushion, the heat radiation emitted by the human body and the cold air on the ground still form direct convection. , which greatly reduces the heat preservation effect. If the number of layers of the air cushion is increased, the heat preservation performance can be improved. However, correspondingly, the weight of the air cushion will also increase, which will increase the burden on the carrier.
