In specific application, the air valve assembly can be integrally installed on the inflatable cushion, and users can rapidly inflate inflatable products by repeatedly pressing the air storage bag. By arranging the first check valve and the second check valve, the inflatable product can be quickly inflated, and at the same time, the air of the inflatable product can be prevented from leaking to the outside during the inflation process, thus improving the air tightness of the inflatable product. ## Claims ### Claim 1 An air valve assembly comprising: an air storage bag; and at least one first check valve communicated with the air storage bag, wherein an air inlet of said first check valve is communicated with the external environment, and an air outlet of said first check valve is communicated with the air storage bag; and at least one second check valve communicated with the air storage bag, wherein an air inlet of said second check valve is communicated with the air storage bag, and an air outlet of said second check valve is communicated with a chamber of an inflatable product; a shell, wherein said at least one first check valve and said at least one second check valve are both arranged on said shell; a buffer air chamber arranged in said shell, and said buffer air chamber is communicated with said air storage bag, said at least one first check valve and said at least one second check valve are communicated through said buffer air chamber, and said shell is arranged in said buffer air chamber of said inflatable product; and wherein, said air storage bag is formed by an air-tight and elastic sheet protruding from one side to the other, and said air storage bag has an edge with a first groove and a second groove, and said first check valve and said second check valve are respectively arranged in said first groove and said second groove. ### Claim 2 (depends on 1) The air valve assembly according to claim 1, wherein hot-melt components are sleeved on the outer walls of said first check valve and said second check valve, and said hot-melt components are fixedly arranged in said shell. ### Claim 3 (depends on 2) The air valve assembly according to claim 2, wherein said hot-melt component comprises a first sleeve and a second sleeve which are clamped with each other, and said first check valve or said second check valve is embedded between said first sleeve and said second sleeve. ### Claim 4 (depends on 3) The air valve assembly according to claim 3, wherein an end of said at least one first check valve and an end of said at least one second check valve are both provided with snap rings, and said first sleeve and said second sleeve are respectively provided with a first clamping groove and a second clamping groove which are matched with both ends of said snap rings. ### Claim 5 (depends on 2) The air valve assembly according to claim 2, wherein said hot-melt component and said shell are both made of hot-melt materials, said at least one first check valve and said at least one second check valve are both made of elastic silica gel; and said at least one first check valve and said at least one second check valve are bonded to said hot-melt component, and said hot-melt component is hot-melt connected with said shell. ### Claim 6 (depends on 1) The air valve assembly according to claim 1, wherein said at least one first check valve comprises a valve body connector, which has a hollow structure; and a valve body is arranged in said valve body connector, and said valve body comprises a circular air inlet and a conical air outlet, and a ball is arranged in said air outlet; and wherein, one end of said valve body connector close to said air outlet is provided with a resisting part for preventing said valve body and said ball from slipping out of said valve body connector. ### Claim 7 (depends on 6) The air valve assembly according to claim 6, wherein said air inlet of said valve body is also provided with a tail part for preventing said valve body from falling out of said valve body connector. ### Claim 8 (depends on 6) The air valve assembly according to claim 6, wherein said valve body is made of a hard material; and said valve body connector is made of a flexible hot-melt material.
