Abstract

A fusion structure, an inflatable product having the fusion structure, a manufacturing method thereof, and a rapidly produced inflatable product having a covering layer simultaneously positioned with an inflatable body are provided. The fusion structure of the inflatable product includes a fusion unit, and the fusion unit includes a target fusion layer, a first fusion reinforcement layer and a first auxiliary fusion layer which are fused together. The fusion reinforcement layer and the auxiliary fusion layer are alternately disposed at a side of the target fusion layer, while the outermost layers of two sides of the fusion unit are the target fusion layer and the auxiliary fusion layer. Alternatively, the fusion reinforcement layer and the auxiliary fusion layer are alternately disposed at two sides of the target fusion layer, while the outermost layers of two sides of the fusion unit are auxiliary fusion layers.

Claims3

Dependent claims

An inflatable product comprising:

a first sheet;
and
a second sheet;
wherein the first sheet and the second sheet are connected by a fusion structure;
the fusion structure comprises at least one fusion unit;
the fusion unit comprises a target fusion layer, at least one fusion reinforcement layer and at least one auxiliary fusion layer which are fused together;
the fusion reinforcement layer and the auxiliary fusion layer are alternately disposed at a side of the target fusion layer, or both the fusion reinforcement layer and the auxiliary fusion layer are alternately disposed at each of two sides of the target fusion layer;
a material of the target fusion layer is the same as or compatible with that of the auxiliary fusion layer;
wherein an air chamber is formed between the first sheet and the second sheet, an anti-stretch sheet is disposed within and/or outside the air chamber, and the anti-stretch sheet is fixed to the fusion structure for covering the air chamber or being covered by the air chamber;
wherein the fusion unit comprises a target fusion layer, a second auxiliary fusion layer, a first fusion reinforcement layer and a first auxiliary fusion layer which are sequentially arranged;
a portion of the first fusion reinforcement layer is wrapped by a cloth and is then fixed to the anti-stretch sheet by sewing;
the target fusion layer, the second auxiliary fusion layer, an unwrapped portion of the first fusion reinforcement layer that is not wrapped by the cloth, and the first auxiliary fusion layer are connected by fusion, and the anti-stretch sheet covers the target fusion layer.
