Abstract

The switch connector with an air flow direction switch function of the present invention comprises a combination seat and a controller. The combination seat comprises a connection part, a gas outlet part and a gas inlet part. The connection part can be coupled to the vessel. The controller is movably located at the combination seat relative to the combination seat between a first position and a second position. As the controller is at the first position, the air inputted into the gas inlet part can flow to the connection part, and the air cannot flow to the gas outlet part through the gas inlet part and the connection part. As the controller is at the second position, the air can flow to the gas outlet part through the connection part to be outputted. The air inputted into the gas inlet part can flow to the gas outlet part to be outputted, and the air cannot flow to the connection part through the gas inlet part. With the switch connector of the aforesaid structure, as the high pressure air in the vessel is not enough, it can be directly connected to the inflating pump to supplement the tire pressure.

Description

Gas storage device with switching airflow direction function and switching joint thereof

The invention mainly discloses a switching joint, in particular a switching joint having a function of switching airflow direction.

Generally, the tires on the market are basically divided into two types: inner tube type tires and tubeless type tires. The inner tube type tires have a layer of inner tubes for storing air inside the tires, and tubeless tires have no inner tubes, and the tires are directly used for the tires and wheels. Sealed inside, tubeless tires have been on the steam locomotive for many years, but the bicycle has not been adopted in order to take into account the weight, the convenience of the wheel steel wire weaving and the convenience of tire disassembly, until recently it began to Popularized in the market.

Although the overall weight of the tubeless tire is reduced, and the friction caused by the rolling between the inner tube and the outer tube and the resistance of the compressed inner tube are reduced, the rolling can be made smoother, but also because there is no inner tube, when the tire is damaged, the tire is replaced. When you want to re-inhale, if you use a normal pump to pump air, the air will leak again through the gap between the tire and the rim, making it difficult to fill.

For this reason, when the tubeless tire is generally inflated, the high-pressure gas cylinder is combined with the nozzle joint to inflate the tire. Because the high-pressure gas cylinder has high-pressure air, the air can be poured into the tire in a very short time. Before the air leaks through the gap between the tire casing and the rim, the high pressure air can squeeze the tire casing so that the tire casing closely abuts the rim, and the gap between the tire casing and the rim is sealed.

However, the above-mentioned filling method is very depleted of the user's financial resources, and the user needs to consume a high-pressure gas cylinder every time the pumping action is performed, and the high-pressure gas cylinder is a consumable item, and the user needs to pay more than the conventional conventional pump. A high cost can be achieved.
