This solution provides a one-way valve (air return valve) in fluid communication from the ambient atmosphere into the system, which when there is a leak in the air tightness of the system, replenishes air from the ambient atmosphere into the system, allowing the inflated deformed stretched structure to still fill it sufficiently and quickly, as shown in figure 1, by a simple cross-cut 245 in the moulded balloon connected to a small hole 240 as a control for varying air flow. Orifice 240 valve 235 in closed mode₁For slow release. Open cross cut 245 valve 235 in open mode₂For increased air intake. The mechanism also ensures that the amount of air removed from the air bag is greater than the minimum required to activate the bounce air bag, and any excess air volume can be safely diverted through the air return valve and reduce the air pressure which can increase the risk of damage, for improving the performance of the plastic bounce air bag and reducing the risk of damage thereto.

However, the one-way valve is formed on an inflatable deformation stretching structure, higher requirements are provided for the mould, the material elasticity and the forming precision, the design space of a product is limited, the manufacturing cost and the yield are restricted, a designer actively researches and innovates based on practical experience and professional knowledge which are rich for many years in the design and manufacture of the product and the application of the theory, and an one-way air return mechanism with a novel structure is designed on a plastic bounce air bag, so that the one-way air return mechanism has higher practicability. Through continuous research and design, and after repeated trial production of samples and improvement, the utility model is finally created to ensure practical value.
