[0002] At present, when people use vacuum storage bags to organize clothes in daily life, they need to use air pumps to pump air, and when using inflatable toys such as swimming rings, they need to use inflatable tubes with large nozzles to inflate. To inflate with an air cylinder with an air needle, since there is currently no air cylinder that can pump air and inflate a variety of inflatable products, many people often need to buy three types of air cylinders at home, which is a waste of money and expensive to carry and store. kind of hard

The invention discloses a deflating and inflating three-functional air pump of front side suction type. The deflating and inflating three-functional air pump of front side suction type comprises a cylinder body, a handle, a push rod, a one-way exhaust valve, an air needle for inflating a ball, an inflating nozzle for inflating a swimming ring, a balloon and other inflatable toys, a back cylinder cover, and a piston positioned in the cylinder body and connected with the push rod, wherein a tubular lug boss extending outwards by a certain length is processed at the front end of the cylinder body; the air needle is in sealed connection with an inner hole of the tubular lug boss through threaded connection; the inflating nozzle is sleeved on the outer part of the tubular lug boss and is in sealed connection with the tubular lug boss; an air suction pipe extending outwards is processed on the side wall of the front end of the cylinder body; and a one-way inlet valve is arranged in the air suction pipe. Only one air pump is required to deflate air and inflate the swimming ring, the ball and other products, so that the deflating and inflating three-functional air pump of front side suction type is economical and labor-saving, and is more convenient to store.
Description
technical field [0001] The invention relates to an inflator, in particular to a front-side suction three-function pumping and charging device which can not only pump air for a vacuum storage bag, but also inflate toys with large nozzles such as swimming rings, and inflate small nozzles such as balls. pump. Background technique [0002] At present, when people use vacuum storage bags to organize clothes in daily life, they need to use air pumps to pump air, and when using inflatable toys such as swimming rings, they need to use inflatable tubes with large nozzles to inflate. To inflate with an air cylinder with an air needle, since there is currently no air cylinder that can pump air and inflate a variety of inflatable products, many people often need to buy three types of air cylinders at home, which is a waste of money and expensive to carry and store. kind of hard. Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
