  "textContent": "An air inflation-deflation valve includes an inflation head, a rubber seat, an inner sleeve, a shell, a first elastic part, a plug chamber, an air inlet rubber plug, a second elastic part and an air outlet rubber plug. When the air inflation-deflation valve is in use, the inflation head is inserted into a rubber chamber to contact an air port, external air enters an air passage, pushing open the air inlet rubber plug, and then enters inner chambers of inflatable products. After inflation, the second elastic part blocks the air passage. During deflation, the inflation head drives the rubber seat and inner sleeve to move, causing the air outlet port to open, thus the air is discharged through the inflation head. An overall structure of the air inflation-deflation valve is simple, easy to use, quick for inflation and deflation, and meets needs of various inflatable products.",
