Title:
AIR VALVE ASSEMBLY AND INFLATABLE CUSHION
Document Type and Number:
WIPO Patent Application WO/2022/198727
Kind Code:
A1
Abstract:
An air valve assembly, comprising: an air storage bag (750); a first one-way valve (200), there being at least one first one-way valve, an air inlet being communicated with the external environment, and an air outlet being communicated with the air storage bag (750); and a second one-way valve (300), there being at least one second one-way valve, an air inlet being communicated with the air storage bag (750), and an air outlet being communicated with a chamber of an inflatable product. When the air valve assembly is specifically applied, the air valve assembly can be integrally mounted on the inflatable product, and a user can rapidly inflate the inflatable product by repeatedly pressing the air storage bag (750). In the air valve assembly, the first one-way valve (200) and the second one-way valve (300) work in conjunction with each other, so that while it is ensured that the inflatable product is rapidly inflated, air in the inflation product is prevented from leaking to the outside in the inflation process, thereby improving the air tightness of the inflatable product.
