Description

Inflatable cushion structure

The present invention relates to an inflatable cushion structure, in particular to providing an inflatable cushion with multiple interlayers to achieve thermal insulation performance.

Press, general inflatable mattresses are used outdoors, such as mountain climbing, outdoor outings, etc., and can be deflated and inflated for the user's convenience to carry and use. Please refer to the first picture, where the inflatable mattress The air cushion 10 is mainly covered with a mutually bondable and airtight adhesive film layer (TPU) in the upper and lower surface layers 11 and 12, and is sealed and fused around the upper and lower surface layers 11 and 12 by a welding machine. Bonded to form a plurality of parallel and connected air channels 13, and an air valve 14 is provided on one side of the inflatable cushion 10. Through the air intake of the air valve 14, the air can flow through the air channels 13 and fill the entire inflatable cushion. 10, the inflatable cushion 10 is made elastic, so that the user can lie down when mountain climbing or in the wild. In order to achieve the effect of keeping warm, some operators fill the airway 13 with thermal insulation materials, such as down, fluff, etc. Light objects such as cotton batting can achieve the effect of keeping warm. However, the fluff, cotton batting and other light objects are filled in the air passage 13. Due to the circulation of air, the fluff, cotton batting and other light objects cannot be fixed in the same position. As a result, the thermal insulation material in the inflatable cushion 10 is unevenly filled, thereby causing poor thermal insulation effect and affecting the inflation speed.

For this reason, the creator of this case has been engaged in the design and manufacturing of inflatable mattresses for many years.

An inflatable cushion with a gap formed between the upper and lower surface layers of the air cushion to slow down the flow of air in the airway to achieve a warming effect.

Another purpose of this invention is to provide an isolation material group in each air channel through the inflatable cushion. The isolation material group is made of soft materials such as aluminum film or polyester film material to form an isolation material group. It is an inflatable mattress that is bendable and has high reflectivity and low absorptivity to effectively reduce temperature radiation and achieve a thermal insulation effect.

In order to achieve the above purpose, this invention mainly forms a plurality of parallel and connected air channels in an inflatable cushion. The air channels are equipped with a connecting piece set. The connecting piece set is mainly made of TPU or other plastic soft materials. It is composed of a connecting piece and a second connecting piece. The first connecting piece is positioned on the left side of the airway. The first connecting piece has its first upper and lower adhesive parts above it and the inner rubber film layer of the upper and lower surfaces of the inflatable cushion ( TPU) is sintered and positioned, and a plurality of first transverse slots arranged at intervals up and down are provided on the first connecting piece, and the second connecting piece is positioned on the right side of the airway, with the second connecting piece above it The two upper and lower bonding parts are fused and positioned with the upper and lower surface inner rubber film layers (TPU) of the inflatable cushion, and a plurality of second transverse slots arranged at intervals up and down are provided on the second connecting piece, and the isolation The material group is composed of a plurality of isolation diaphragms.
