Problems solved by technology
[0002] At present, the swimming ring is a ring body, which is inflated or filled with non-inflatable materials. Once the inflated swimming ring is punctured, it can no longer provide floats, and the safety is poor; while the internal filling of non-inflatable materials is generally rigid foam. Materials or soft foaming materials, etc., the hard foam is relatively hard, the ring body jacket has no support, and the comfort is poor; and the soft foaming material cannot be formed on the curved or convex part of the surface due to technological reasons. The function is relatively single, and the appearance is not beautiful; in addition, the surface coating layer of the existing non-inflatable swimming ring is impermeable and breathable. In order to prevent internal water accumulation, it is necessary to poke several drainage holes on the coating layer

Abstract
The invention relates to a non-inflatable swimming ring with a multi-layer structure. The non-inflatable swimming ring with the multi-layer structure comprises a ring body. The ring body comprises aninner non-inflatable foaming material and an outer wrapping layer. The inner non-inflatable foaming material is a rigid foaming material and a soft foaming material, the rigid foaming material and thesoft foaming material are layered upwards and downwards in a laminated mode, and the uppermost layer is the rigid foaming material. The inner non-inflatable foaming material is wrapped by the wrapping layer. According to the non-inflatable swimming ring with the multi-layer structure, various shapes can be achieved, and the ring can be deformed to a certain extent. The non-inflatable swimming ring with the multi-layer structure has the characteristics of comfort, reliability and beauty.
