Pumps can be bought in supermarkets, grocery stores and auto repair shops.
The inflator is an air pump, which sucks air into the storage area by pulling, and then injects or supplements the air needed by various tires and some ball games by pushing.
The traditional vertical inflator is the most common inflator, which has the effect of rapid inflation and is relatively easy and labor-saving. Almost all the previous 28 big bars used this pump.
